Definitions
- the invention relates to a shaping device for producing a component carrier tape by forming component pockets in a raw tape.
- Component carrier tapes are used to transfer electronic components, for example memory chips, chips with integrated circuits, resistors, capacitors etc. from the manufacturer of the components to the processor of the components assembles new products to transport.
- a component carrier tape comprises a plurality of pockets, which are arranged one behind the other on the tape over its length and serve as receptacles for the components.
- the component carrier tape typically consists of a thermoplastic material in which the pockets are formed. Different shaping devices are available for shaping the pockets when producing the component carrier tape from a raw tape.
- the raw strip is first heated and then passed over a molding wheel that has depressions.
- the heated strip is pressed into the mold recesses of the molding wheel by compressed air using a nozzle.
- the depressions of the molding wheel are often evacuated, so that the vacuum created thereby also pulls the warm raw strip into the mold.
- the belt cools, the pockets formed in this way solidify.
- the pockets are formed in a continuous sequence in rotary molding devices, the pockets are formed in a cyclical process sequence in press-forming devices.
- Such shaping devices comprise a shaping tool with a stamp and a die, between which the previously heated raw strip is introduced in a first step, the component carrier strip formed in the previous cycle being removed from the shaping tool at the same time. Then the mold is closed in the next step, whereby the pockets are pressed into the raw strip. Then the cycle repeats. When the band cools down, the shaped pockets solidify.
- a press-forming device for producing component carrier tape in which a molding tool for shaping the pockets is used. finds, is described for example in EP 0 809 925.
- the molding tool comprises a stationary die, which is therefore not moved during the manufacturing process, and a movable stamp for shaping the component pockets.
- a machine for producing component carrier strip can process a certain throughput of raw strip per hour.
- the production of component carrier tape can be increased by either increasing the number of machines or the throughput of the machines.
- State-of-the-art machines with molding wheels or molding tools for shaping the pockets in the component carrier belt create a throughput of up to approximately 340 m of belt per hour.
- the person skilled in the art therefore has the task of providing a device for shaping component carrier tape, with which higher tape speeds can be achieved.
- the shaping device for producing a component carrier tape by forming component pockets in a raw tape comprises a molding tool with two half parts arranged above and below the continuous raw tape, wherein a first half part comprises a movably mounted die, which can be displaced in the direction of the raw strip or during the opening process away from the raw strip by means of a closing and opening device, and fixes the raw strip in the closed state of the molding tool and
- a second half part comprises a movably mounted stamp which can be displaced in the direction of the raw strip or during the opening process away from the raw strip by means of a closing and opening device and which forms the component pockets in the fixed raw strip and
- a transport device for transporting the raw strip to be machined and the finished component carrier strip in the opened state of the molding tool in and out of the molding tool.
- the invention is based on the following considerations:
- the maximum possible belt speed is determined on the one hand by the number of possible strokes of the molding tool and the number of pockets produced per stroke.
- the number of pockets that can be formed per stroke in turn depends on the pocket size. Since a certain force is required to form a pocket, only a certain number of pockets can be formed with a certain pressing force of the molding tool, which pockets take up a certain length of the band.
- the claimed tape length is called the index length.
- index lengths of 56 mm are common, for large pockets index lengths of 144 mm per stroke.
- the machines need for a stroke according to the prior art, approx. 1.5 seconds, which, for example with an index length of 144 mm per stroke, leads to a processing speed (belt speed) of approx. 340 m / h.
- the manufacturing process can be further accelerated with the molding device according to the invention, which comprises both a movable plunger and a movably mounted die.
- the molding device according to the invention which comprises both a movable plunger and a movably mounted die.
- particularly high closing forces can be transmitted via a movably mounted die.
- a high clamping force allows the mold to accelerate quickly when closing and thus enables a large number of strokes per hour.
- the large closing force allows many component pockets to be formed with one closing operation, so that the molding tool can be equipped with many stamps over a long index length. Both the high acceleration of the forming tool and the many stamps make it possible to increase the processing speed when forming the pockets. There is no need for a conventional ejection device.
- the punch and die are each connected to a separate locking device, so that the punch and the die can exert different forces on the raw strip when the component pockets are formed.
- the closing and opening devices of the stamp and the die are at least indirectly operatively connected to one another, so that a coordination of the movements of the punch and die is possible during the production of the component pockets.
- the movement sequences are coordinated such that the raw strip remains in its plane during the entire manufacturing process, that is to say is not moved relative to the components of the molding tool. This enables a particularly high level of precision to be achieved during the molding process, since slipping of the raw strip in the molding tool is avoided.
- the closing device preferably comprises a compression spring, in particular a pneumatic spring.
- the pneumatic spring has less mass than other springs, for example a spiral or leaf or torsion spring, as a result of which the acceleration of the mold when opening and closing and thus the number of strokes per hour can be increased further.
- Belt speeds of 700 m / h or more can be achieved in this way.
- the pneumatic spring comprises a compressed air bellows to which compressed air is applied.
- This embodiment can be designed with particularly low mass. It also facilitates access to the working area of the mold, for example for maintenance purposes or for changing the die and stamp. By venting the bellows, for which e.g. If a venting device is provided, the closing force can be reduced, so that the molding tool can be opened without great effort.
- Adjusting the compressed air pressure enables the closing force of the closing device to be easily adjusted, as a result of which the shaping device easily meets changing requirements, such as the thickness of the band or the dimensions of the component pockets to be formed can be adjusted.
- the opening device comprises a shaft and a cam disk arranged on the shaft and driven by it.
- the driven cam disk enables the mold to be opened cyclically against the closing force of the closing device in a simple manner.
- a separate cam wheel can be assigned to the punch and the die, which means that different movements for the punch and die can be realized.
- the opening devices of the stamp and the die are preferably connected to one another in an articulated manner. because the movement sequences of the components can be coordinated particularly easily.
- stamp is arranged below the raw strip. In practice, this arrangement provides particularly precise results in the molding process.
- a peripheral edge of the die forms a support for the longitudinal straps of the raw strip.
- a work plate of the molding tool which has a cutout opening for the stamp, functions as a counter-support for the raw strip. This prevents the raw strip from slipping during the manufacturing process.
- a fixing plate floating on the work plate via spring elements forms the counter-support. The slight play of the spring elements of approx. 0.2 to 0.3 mm allows. it compensates for differences in thickness in the raw strip and leads to a more even distribution of the applied compressive forces.
- the shaping device is characterized in that the shaping tool comprises a heating device for heating the raw strip and / or a punching device for producing a control hole in the bottom of the component pockets.
- the heating enables the component bags to be hot-pressed when the component carrier tape is being manufactured, and the control hole when the finished component carrier tape is used later enables the component bags to be checked when filling or emptying.
- the heating device and / or the perforating device can be implemented in separate, cyclically closing and opening tools, the tools imparting a closing pressure.
- Each tool is equipped with a closing device for supplying the closing pressure and an opening device for opening the tool, the closing device being a compression spring for generating the Includes closing pressure and the opening device is designed to open the mold against the closing pressure.
- the separate design of the tools makes it possible to assign an individual closing pressure to each tool.
- the closing pressure of the heating tool can, for example, be lower than that of the molding tool.
- the component carrier tape is usually not yet completely cold again at the time of the perforation.
- the remaining heat can lead to complications when forming the control hole.
- the omission of that area of the raw strip in which the control hole will be formed later helps to avoid these complications. It is therefore particularly advantageous if the heating device is designed such that it does not heat that area of the raw strip that forms the bottom area of the component pocket in the finished component carrier strip, into which the punching device makes the control hole.
- the molding device has a synchronizing device for synchronizing the transport device with the cyclical opening and closing of the molding tool, the heating device and the punching device, so that the work processes of the molding device run as synchronously as possible.
- the transport device can comprise a drive for imparting a gradual advance to the component carrier belt or the raw belt.
- the synchronizing device can be implemented by a trigger arranged on the shaft to trigger the advance steps.
- the shaping device has a cutting device, which is arranged downstream of the shaping tool and a transport direction of the raw or component carrier tape and is designed to divide the shaped component carrier tape in the longitudinal direction.
- the molding tool is preferably designed det, at least two in the longitudinal direction of the component carrier tape side by side arranged component pockets into the component carrier band, so that at least two rows of component pockets arranged next to each other are created on the component carrier band.
- the cutting device is preferably arranged relative to the molding tool in such a way that the cutting device divides the component carrier tape in the longitudinal direction between the component pockets formed next to one another. In this way, several component carrier tapes can be produced from one raw strip, so that the production of such component carrier tapes can take place particularly quickly and efficiently.

- FIG. 2a the molding device in a schematic side view
- FIG. 2b shows an alternative embodiment of the molding device in a schematic side view
- FIG. 3 shows a further embodiment of the molding device in a schematic front view
- Figure 4 shows a further embodiment of the molding device in a perspective view
- FIG. 5 is another perspective view of the embodiment shown in Figure 4.
- the structure and function of the device according to the invention for forming a component carrier tape 1 will now be described with reference to FIGS. 1a and 1b.
- the device comprises a molding tool 9 and a transport device 5, 7 for transporting the component carrier tape 1.
- the transport device 5, 7 can, for example, be a toothed wheel with teeth for engagement in the index holes of the tape (the index holes represent a perforation in a side strip of the tape ) include and can be designed to guide the tape at the same time.
- It also includes a motor, in the exemplary embodiment a servo motor (not shown), which provides the belt 1 with a gradual advance.
- the molding tool 9 comprises two half parts 36, 38 with a punch 17 and a die 19, between which the component carrier tape 1 is passed.
- the feed device 5, 7 feeds the component carrier belt 1.
- this molding tool 9 is closed (FIG. 1b) as soon as there is a section of the raw belt 2 in which the component pockets 3 are formed are located between the stamp 17 and the die 19.
- Both the punch 17 and the die 19 are movably supported and are moved in the direction of the raw strip 2 or moved away from the raw strip 2 by an opening and closing device 40, 42 during the manufacturing process.
- the movement of the two components of the molding tool 9 is coordinated with one another in such a way that the raw strip 2 is not pressed out of its transport plane.
- a counter-receptacle is formed by a fixing plate 48 applied to a work plate 46 of the molding device.
- spring elements 50 are arranged in suitable cutouts in the two parts.
- the spring elements allow a play of approx. 0.2 to 0.3 mm between the work plate 46 and the fixing plate 48.
- the small play of the spring elements 50 allows differences in thickness in the raw strip 2 to be compensated for and leads to a more even distribution of the compressive forces that are applied.
- Work plate 46 and fixing plate 48 have a cutout opening through which the stamp 17 can pass.
- FIG. 2a shows a side view of the molding device in the area of the molding tool 9 in a special embodiment, in which, for simplicity, the representation of the work plate 46 or the fixing plate 48 has been omitted.
- the mold 9 is closed by a pneumatic spring connected to the plunger 17 and the die 19, each of which comprises a compressed air bellows 11.1, 11.2 loaded with compressed air.
- the compressed air bellows 11.1, 11.2 are therefore part of the closing device of the molding tool 9.
- an adjusting device not shown in the figures
- the pressure of the compressed air in the bellows 11.1, 11.2 can be varied and thus the spring force of the compressed air spring formed by the compressed air bellows 11.1, 11.2 can be set. len. This can be useful, for example, if raw strips 2 with different strip thicknesses are used. According to DIN standard IEC 286 III, strip thicknesses between 0.3 and 0.6 mm are possible.
- the punch 17 and the die 19 are connected to one another in an articulated manner via two levers 25 and a joint 27 (FIG. 2a).

- the shaft 15, on which the cam plate 13 is arranged is driven by a three-phase motor with adjustable speed, so that the cam plate 13 rotates at a certain frequency.
- the levers 25 are always pressed against the circumferential surface of the cam plate 13 by the pressure force of the compressed air bellows 11.1, 11.2.
- the rotation of the cam disc 13 therefore results in a pincer-shaped opening and closing movement of the molding tool 9, the largest opening of the molding tool 9, ie the greatest spread of the levers 25, being given by the large semiaxis of the ellipse and the smallest opening being the small semi-axis.
- the elliptical shape of the cam plate 13 is chosen here only to simplify the illustration. It goes without saying that the shape of the circumferential surface of the cam disk 13 can be selected differently depending on the actual movement sequence. In addition, it is possible to provide a separate cam disk for each lever 25 instead of a common cam disk 13. However, this complicates the coordination of the movements.
- the bellows 11.1, 11.2 can be vented, for example, via the adjusting device for adjusting the air pressure or via a specially provided venting device. After the bellows 11.1, 11.2 have been vented, the lever 25 can be lifted off the cam disk 3 without great effort.

Downstream of the molding tool 9 is a hole device 23 with which 3 holes are made in the bottoms of the molded component pockets, through which the filling state of the pocket can be determined later when the component pockets 3 are filled or emptied.
- Both the heating device 21 and the perforating device 23, like the molding tool 9, are designed such that they go through a cycle of opening and closing.
- a synchronizing device (not shown) which synchronizes the cycles of the heating device 21, the molding tool 9 and the punching device 23 with the transport of the band 2 through the transport device 5, 7 in such a way that the band 2 is transported further when the heating device 21, the mold 9 and the punch device 23 are open.
- the synchronizing device is also present if the molding device is only equipped with a molding tool 9 but not with a heating device 21 or perforating device 23.
- the synchronization of the molding tool 9 with the heating device 21 and the punching device 23 is provided in that the cam disks assigned to them are arranged on a common shaft 15.
- the opening and closing of the heating device 21 and the punching device 23 is carried out in the same way as the opening and closing of the molding tool 9.
- the closing force generated by the compressed air bellows 11 can be lower than that of the compressed air bellows 11.1, 11.2 of the molding tool 9.
- the heating device 21 does not require a high closing force.
- the closing force is adjusted, as in the mold 9, by adjusting the compressed air with which the compressed air bellows 11 is acted upon.
- an adjusting device (not shown) is provided, with which the compressed air pressure of each bellows 11 can be adjusted individually.

- Base plates 12, 12 'for the bellows 11.1, 11.2, 11 are provided at the ends of the levers 25 remote from the joints 27a and 27b.
- the base plate 12 ′ has a smaller diameter than the base plate 12 because it is assigned to the heating device 21.
- the heating device 21 only requires a lower closing force than the molding tool 9. Therefore, the bellows 11 for the heating device 21 only need to apply a lower maximum closing force than the bellows 11.1, 11.2 for the molding tool 9. Accordingly, they can be compared to the bellows 11.1, 11.2 have smaller dimensions for the molding tool 9.
- cam plates 13a and 13b are assigned to each pair of levers 27a, 27b, one for each lever.
- the cam disks are driven by a shaft 15, which in turn is driven by the three-phase motor 30.

FORMVORRICHTUNG ZUR HERSTELLUNG EINES KOMPONENTENTRAGERBANDES FÜR ELEKTRONISCHE BAUTEILEMOLDING DEVICE FOR PRODUCING A COMPONENT CARRIER TAPE FOR ELECTRONIC COMPONENTS
Die Erfindung betrifft eine Formvorrichtung zur Herstellung eines Kom- ponententrägerbandes durch Formen von Komponententaschen in einem Rohband.The invention relates to a shaping device for producing a component carrier tape by forming component pockets in a raw tape.
Komponententrägerbänder werden dazu verwendet, elektronische Komponenten, beispielsweise Speicherchips, Chips mit integrierten Schaltkreisen, Widerstände, Kondensatoren etc. vom Hersteller der Komponenten zum Verarbeiter der Komponenten, der die Komponenten zu neuen Produkten zusammenbaut, zu transportieren. Zur Aufnahme der Komponenten umfasst ein solches Komponententrägerband eine Vielzahl von Taschen, die auf dem Band über dessen Länge verteilt hintereinander angeordnet sind und als Aufnahmen für die Komponenten die- nen.Component carrier tapes are used to transfer electronic components, for example memory chips, chips with integrated circuits, resistors, capacitors etc. from the manufacturer of the components to the processor of the components assembles new products to transport. To hold the components, such a component carrier tape comprises a plurality of pockets, which are arranged one behind the other on the tape over its length and serve as receptacles for the components.
Typischerweise besteht das Komponententrägerband aus einem thermoplastischen Material, in dem die Taschen ausgeformt sind. Zum Ausformen der Taschen beim Herstellen des Komponententrägerbandes aus einem Rohband stehen unterschiedliche Formvorrichtungen zur Verfügung.The component carrier tape typically consists of a thermoplastic material in which the pockets are formed. Different shaping devices are available for shaping the pockets when producing the component carrier tape from a raw tape.
In Rotationsformvorrichtungen wird das Rohband zuerst erwärmt und dann über ein Formrad geführt, das Vertiefungen aufweist. Mittels einer Düse wird das erwärmte Band per Druckluft in die Formvertiefungen des Formrades gepresst. Gleichzeitig werden häufig die Vertiefungen des Formrades evakuiert, so dass das dadurch entstehende Vakuum das warme Rohband zusätzlich in die Form zieht. Mit Erkalten des Bandes verfestigen sich die so ausgeformten Taschen.In rotary molding devices, the raw strip is first heated and then passed over a molding wheel that has depressions. The heated strip is pressed into the mold recesses of the molding wheel by compressed air using a nozzle. At the same time, the depressions of the molding wheel are often evacuated, so that the vacuum created thereby also pulls the warm raw strip into the mold. When the belt cools, the pockets formed in this way solidify.
Während in Rotationsformvorrichtungen das Bilden der Taschen in einem kontinuierlichen Ablauf geschieht, erfolgt in Pressformvorrichtungen das Formen der Taschen in einem zyklischen Prozessablauf. Derartige Formvorrichtungen umfassen ein Formwerkzeug mit einem Stempel und einer Matrize, zwischen die das zuvor erwärmte Rohband in einem ersten Schritt eingeführt wird, wobei gleichzeitig das im vorangegangenen Zyklus ausgeformte Komponententrägerband aus dem Formwerkzeug entfernt wird. Danach wird im nächsten Schritt das Formwerkzeug geschlossen, wodurch die Taschen in das Rohband gepresst werden. Danach wiederholt sich der Zyklus. Mit Erkalten des Bandes verfestigen sich dann die ausgeformten Taschen.While the pockets are formed in a continuous sequence in rotary molding devices, the pockets are formed in a cyclical process sequence in press-forming devices. Such shaping devices comprise a shaping tool with a stamp and a die, between which the previously heated raw strip is introduced in a first step, the component carrier strip formed in the previous cycle being removed from the shaping tool at the same time. Then the mold is closed in the next step, whereby the pockets are pressed into the raw strip. Then the cycle repeats. When the band cools down, the shaped pockets solidify.
Eine Pressformvorrichtung zum Herstellen von Komponententräger- band, in der ein Formwerkzeug zum Ausformen der Taschen Verwen- dung findet, ist beispielsweise in EP 0 809 925 beschrieben. Das Formwerkzeug umfasst eine stationäre Matrize, die während des Herstellungsprozesses also nicht bewegt wird, und einen beweglichen Stempel zur Ausformung der Komponententaschen.A press-forming device for producing component carrier tape, in which a molding tool for shaping the pockets is used. finds, is described for example in EP 0 809 925. The molding tool comprises a stationary die, which is therefore not moved during the manufacturing process, and a movable stamp for shaping the component pockets.
Aufgrund der großen Mengen an elektronischen Komponenten, die weltweit produziert und transportiert werden, benötigt die Industrie solche Komponententrägerbänder in großen Mengen. Es besteht daher ein Bedarf, große Mengen an Komponententrägerband kostengünstig zu produzieren.Due to the large quantities of electronic components that are produced and transported worldwide, the industry needs such component carrier tapes in large quantities. There is therefore a need to produce large quantities of component carrier tape inexpensively.
Eine Maschine zum Herstellen von Komponententrägerband kann einen bestimmten Durchsatz an Rohband pro Stunde bearbeiten. Die Produktion von Komponententrägerband lässt sich dadurch erhöhen, dass entweder die Anzahl der Maschinen erhöht wird oder der Durchsatz der Maschinen.A machine for producing component carrier strip can process a certain throughput of raw strip per hour. The production of component carrier tape can be increased by either increasing the number of machines or the throughput of the machines.
Maschinen nach Stand der Technik mit Formrädem oder Formwerkzeugen zum Ausformen der Taschen im Komponententrägerband schaffen einen Durchsatz bis zu etwa 340 m Band pro Stunde.State-of-the-art machines with molding wheels or molding tools for shaping the pockets in the component carrier belt create a throughput of up to approximately 340 m of belt per hour.
Dem Fachmann stellt sich daher die Aufgabe, eine Vorrichtung zum Formen von Komponententrägerband zur Verfügung zu stellen, mit der sich höhere Bandgeschwindigkeiten erzielen lassen.The person skilled in the art therefore has the task of providing a device for shaping component carrier tape, with which higher tape speeds can be achieved.
Diese Aufgabe wird durch eine Formvorrichtung nach Anspruch 1 gelöst. Die Unteransprüche enthalten weitere vorteilhafte Ausgestaltungen der vorliegenden Erfindung.This object is achieved by a molding device according to claim 1. The subclaims contain further advantageous refinements of the present invention.
Gemäß Anspruch 1 umfasst die Formvorrichtung zur Herstellung eines Komponententrägerbandes durch Formen von Komponententaschen in einem Rohband ein Formwerkzeug mit zwei oberhalb und unterhalb des durchlaufenden Rohbandes angeordneten Halbteilen, wobei - ein erstes Halbteil eine beweglich gelagerte Matrize umfasst, die mittels einer Schließ- und Offnungseinrichtung beim Schließvorgang in Richtung des Rohbands bzw. beim Öffnungsvorgang vom Rohband weg verlagerbar ist und im geschlossenen Zu- stand des Formwerkzeugs das Rohband festlegt undAccording to claim 1, the shaping device for producing a component carrier tape by forming component pockets in a raw tape comprises a molding tool with two half parts arranged above and below the continuous raw tape, wherein a first half part comprises a movably mounted die, which can be displaced in the direction of the raw strip or during the opening process away from the raw strip by means of a closing and opening device, and fixes the raw strip in the closed state of the molding tool and
- ein zweites Halbteil einen beweglich gelagerten Stempel umfasst, der mittels einer Schließ- und Öffnungseinrichtung beim Formvorgang in Richtung des Rohbandes bzw. beim Öffnungsvorgang vom Rohband weg verlagerbar ist und die Komponen- tentaschen im festgelegten Rohband ausformt und- A second half part comprises a movably mounted stamp which can be displaced in the direction of the raw strip or during the opening process away from the raw strip by means of a closing and opening device and which forms the component pockets in the fixed raw strip and
eine Transporteinrichtung zum Transportieren des zu bearbeitenden Rohbandes und des fertigen Komponententrägerbandes im geöffneten Zustand des Formwerkzeugs in das bzw. aus dem Formwerkzeug.a transport device for transporting the raw strip to be machined and the finished component carrier strip in the opened state of the molding tool in and out of the molding tool.
Der Erfindung liegen die folgenden Überlegungen zugrunde:The invention is based on the following considerations:
Mit dem Formrad lassen sich nur relativ geringe Bandbreiten bearbeiten und nur relativ kleine Taschen erzeugen. Große Taschen werden daher durch Warmpressen mittels Formwerkzeugen hergestellt.With the form wheel, only relatively small bandwidths can be processed and only relatively small pockets can be produced. Large bags are therefore made by hot pressing using molding tools.
Werden die Taschen mittels Warmpressen hergestellt, so findet, wie oben bereits beschrieben, ein zyklischer Prozessablauf statt. Die maxi- mal mögliche Bandgeschwindigkeit wird dabei zum einen durch die Anzahl der pro Zeiteinheit möglichen Hübe des Formwerkzeuges sowie der Anzahl pro Hub erzeugten Taschen bestimmt. Die Anzahl der pro Hub ausformbaren Taschen hängt wiederum von der Taschengröße ab. Da zum Ausformen einer Tasche jeweils eine bestimmte Kraft nötig ist, kann mit einer bestimmten Presskraft des Formwerkzeugs lediglich eine bestimmte Anzahl Taschen ausgeformt werden, die eine bestimmte Länge des Bandes beanspruchen. Die beanspruchte Bandlänge wird Indexlänge genannt. Beim Herstellen von kleinen Taschen sind beispielsweise Indexlängen von 56 mm, bei großen Taschen Indexlängen von 144 mm pro Hub üblich. Für einen Hub benötigen die Maschinen nach Stand der Technik ca. 1 ,5 Sekunden, was beispielsweise bei einer Indexlänge von 144 mm pro Hub zu einer Verarbeitungsgeschwindigkeit (Bandgeschwindigkeit) von ca. 340 m/h führt.If the bags are manufactured using hot pressing, a cyclical process sequence takes place, as already described above. The maximum possible belt speed is determined on the one hand by the number of possible strokes of the molding tool and the number of pockets produced per stroke. The number of pockets that can be formed per stroke in turn depends on the pocket size. Since a certain force is required to form a pocket, only a certain number of pockets can be formed with a certain pressing force of the molding tool, which pockets take up a certain length of the band. The claimed tape length is called the index length. When manufacturing small pockets, for example, index lengths of 56 mm are common, for large pockets index lengths of 144 mm per stroke. The machines need for a stroke according to the prior art, approx. 1.5 seconds, which, for example with an index length of 144 mm per stroke, leads to a processing speed (belt speed) of approx. 340 m / h.
Mit der erfindungsgemäßen Formvorrichtung, die sowohl einen beweg- lieh gelagerten Stempel als auch eine beweglich gelagerte Matrize umfasst, lässt der Herstellungsprozess weiter beschleunigen. Überraschender Weise hat sich nämlich gezeigt, dass über eine beweglich gelagerte Matrize besonders hohe Schließkräfte übertragbar sind. Eine große Schließkraft erlaubt eine hohe Beschleunigung des Formwerk- zeuges beim Schließen und ermöglicht somit eine große Anzahl Hübe pro Stunde. Außerdem gestattet es die große Schließkraft, viele Komponententaschen mit einem Schließvorgang zu formen, so dass das Formwerkzeug auf einer großen Indexlänge mit vielen Stempeln ausgestattet werden kann. Sowohl die hohe Beschleunigung des Form- Werkzeuges als auch die vielen Stempel, ermöglichen es, die Verarbeitungsgeschwindigkeit beim Formen der Taschen zu erhöhen. Auf eine Auswurfvorrichtung konventioneller Art kann verzichtet werden.The manufacturing process can be further accelerated with the molding device according to the invention, which comprises both a movable plunger and a movably mounted die. Surprisingly, it has been shown that particularly high closing forces can be transmitted via a movably mounted die. A high clamping force allows the mold to accelerate quickly when closing and thus enables a large number of strokes per hour. In addition, the large closing force allows many component pockets to be formed with one closing operation, so that the molding tool can be equipped with many stamps over a long index length. Both the high acceleration of the forming tool and the many stamps make it possible to increase the processing speed when forming the pockets. There is no need for a conventional ejection device.
In einer Ausgestaltung der Erfindung sind Stempel und Matrize, mit jeweils einer gesonderter Schließeinrichtung verbunden ist, so dass der Stempel und die Matrize beim Formen der Komponententaschen unterschiedliche Kräfte auf das Rohband ausüben können.In one embodiment of the invention, the punch and die are each connected to a separate locking device, so that the punch and the die can exert different forces on the raw strip when the component pockets are formed.
Weiterhin ist bevorzugt, dass die Schließ- und Öffnungseinrichtungen des Stempels und der Matrize zumindest mittelbar miteinander wirkverbunden sind, so dass eine Koordination der Bewegungsabläufe von Stempel und Matrize während der Herstellung der Komponententaschen möglich ist. Insbesondere sind die Bewegungsabläufe so abgestimmt, dass das Rohband während des gesamten Herstellungsprozesses in seiner Ebene verweilt, also nicht relativ zu den Komponenten des Formwerkzeugs bewegt wird. Hierdurch kann eine besonders hohe Prä- zision beim Formvorgang erreicht werden, denn ein Verrutschen des Rohbandes im Formwerkzeug wird vermieden. Vorzugsweise umfasst die Schließeinrichtung als Stellglied eine Druckfeder, insbesondere eine pneumatische Feder. Die pneumatische Feder weist gegenüber anderen Federn, beispielsweise einer Spiral- oder Blatt- oder Torsionsfeder, weniger Masse auf, wodurch die Beschleuni- gung des Formwerkzeugs beim Öffnen und Schließen und somit die Zahl der Hübe pro Stunde weiter erhöht werden kann. Bandgeschwindigkeiten von 700 m/h oder mehr sind so realisierbar.It is further preferred that the closing and opening devices of the stamp and the die are at least indirectly operatively connected to one another, so that a coordination of the movements of the punch and die is possible during the production of the component pockets. In particular, the movement sequences are coordinated such that the raw strip remains in its plane during the entire manufacturing process, that is to say is not moved relative to the components of the molding tool. This enables a particularly high level of precision to be achieved during the molding process, since slipping of the raw strip in the molding tool is avoided. As an actuator, the closing device preferably comprises a compression spring, in particular a pneumatic spring. The pneumatic spring has less mass than other springs, for example a spiral or leaf or torsion spring, as a result of which the acceleration of the mold when opening and closing and thus the number of strokes per hour can be increased further. Belt speeds of 700 m / h or more can be achieved in this way.
In einer Ausgestaltung der pneumatischen Feder umfasst diese einen mit Pressluft beaufschlagten Pressluftbalg. Diese Ausführungsform kann besonders massearm ausgestaltet werden. Sie erleichtert außerdem die Zugänglichkeit zum Arbeitsbereich des Formwerkzeuges, beispielsweise zu Wartungszwecken oder zum Wechseln von Matrize und Stempel. Durch Entlüften der Bälge, wofür z.B. eine Entlüftungseinrichtung vorgesehen ist, lässt sich die Schließkraft abbauen, so dass sich das Form- Werkzeug ohne großen Kraftaufwand öffnen lässt.In one configuration of the pneumatic spring, it comprises a compressed air bellows to which compressed air is applied. This embodiment can be designed with particularly low mass. It also facilitates access to the working area of the mold, for example for maintenance purposes or for changing the die and stamp. By venting the bellows, for which e.g. If a venting device is provided, the closing force can be reduced, so that the molding tool can be opened without great effort.
Als vorteilhaft erweist es sich, wenn eine EinStelleinrichtung zum Einstellen des im Pressluftbalg herrschenden Pressluftdrucks vorhanden ist. Das Einstellen des Pressluftdruckes ermöglicht ein einfaches Einstellen der Schließkraft der Schließeinrichtung, wodurch die Formvorrichtung leicht an wechselnde Anforderungen, wie z.B. die Dicke des Bandes oder die Abmessungen der zu formenden Komponententaschen ange- passt werden kann.It proves to be advantageous if an adjustment device for adjusting the compressed air pressure prevailing in the compressed air bellows is present. Adjusting the compressed air pressure enables the closing force of the closing device to be easily adjusted, as a result of which the shaping device easily meets changing requirements, such as the thickness of the band or the dimensions of the component pockets to be formed can be adjusted.
In einer weiteren Ausgestaltung der Erfindung umfasst die Öffnungseinrichtung eine Welle und eine auf der Welle angeordnete und von dieser angetriebene Kurvenscheibe. Die angetrieben Kurvenscheibe ermöglicht in einfach durchzuführender Weise das zyklische Öffnen des Formwerkzeuges gegen die Schließkraft der Schließeinrichtung. Dabei können dem Stempel und der Matrize jeweils eine eigenes Kurvenrad zugeordnet sein, wodurch sich unterschiedliche Bewegungsabläufe für Stempel und Matrize realisieren lassen. Vorzugsweise sind aber der Öffnungseinrichtungen des Stempels und der Matrize gelenkig miteinander verbun- den, denn so lassen sich die Bewegungsabläufe der Komponenten besonders einfach koordinieren.In a further embodiment of the invention, the opening device comprises a shaft and a cam disk arranged on the shaft and driven by it. The driven cam disk enables the mold to be opened cyclically against the closing force of the closing device in a simple manner. A separate cam wheel can be assigned to the punch and the die, which means that different movements for the punch and die can be realized. However, the opening devices of the stamp and the die are preferably connected to one another in an articulated manner. because the movement sequences of the components can be coordinated particularly easily.
Ferner ist bevorzugt, wenn der Stempel unterhalb des Rohbandes angeordnet ist. In der Praxis liefert diese Anordnung besonders präzise Ergebnisse beim Formprozess.It is further preferred if the stamp is arranged below the raw strip. In practice, this arrangement provides particularly precise results in the molding process.
Ein umlaufender Rand der Matrize bildet im geschlossenen Zustand des Formwerkzeugs eine Auflage für die Längsgurte des Rohbandes. Als günstig hat es sich erwiesen, wenn eine Werkplatte des Formwerkzeugs, die eine Ausschnittsöffnung für den Stempel aufweist, als Ge- genauflage für das Rohband fungiert. Hierdurch wird ein Verrutschen des Rohbandes während des Herstellungsprozesses vermieden. Vorzugsweise bildet eine über Federelemente auf der Werkplatte schwimmend gelagerte Fixierplatte die Gegenauflage. Das geringe Spiel der Federelemente von ca. 0,2 bis 0,3 mm erlaubt. es Dickenunterschiede im Rohband zu kompensieren und führt zu einer gleichmäßigeren Verteilung der ansetzenden Druckkräfte.When the mold is closed, a peripheral edge of the die forms a support for the longitudinal straps of the raw strip. It has proven to be advantageous if a work plate of the molding tool, which has a cutout opening for the stamp, functions as a counter-support for the raw strip. This prevents the raw strip from slipping during the manufacturing process. Preferably, a fixing plate floating on the work plate via spring elements forms the counter-support. The slight play of the spring elements of approx. 0.2 to 0.3 mm allows. it compensates for differences in thickness in the raw strip and leads to a more even distribution of the applied compressive forces.
In noch einer weiteren Ausgestaltung der Erfindung zeichnet sich die Formvorrichtung dadurch aus, dass das Formwerkzeug eine Heizvorrichtung zum Heizen des Rohbandes und/oder eine Lochvorrichtung zum Erzeugen eines Kontrollloches im Boden der Komponententaschen umfasst. Das Heizen ermöglicht das Warmpressen der Komponententaschen beim Herstellen des Komponententrägerbandes, das Kontrollloch bei der späteren Verwendung des fertigen Komponententrägerbandes die Kontrolle der Komponententaschen beim Befüllen oder Entleeren.In yet another embodiment of the invention, the shaping device is characterized in that the shaping tool comprises a heating device for heating the raw strip and / or a punching device for producing a control hole in the bottom of the component pockets. The heating enables the component bags to be hot-pressed when the component carrier tape is being manufactured, and the control hole when the finished component carrier tape is used later enables the component bags to be checked when filling or emptying.
Die Heizvorrichtung und/oder die Lochvorrichtung können in getrennten, sich zyklisch schließenden und öffnenden Werkzeugen realisiert sein, wobei die Werkzeuge einen Schließdruck vermitteln. Jedes Werkzeug ist dabei mit einer Schließeinrichtung zum Zuführen des Schließdrucks und einer Öffnungseinrichtung zum Öffnen des Werkzeugs ausgestattet, wobei die Schließeinrichtung eine Druckfeder zum Erzeugen des Schließdrucks umfasst und die Öffnungseinrichtung zum Öffnen des Formwerkzeuges gegen den Schließdruck ausgelegt ist. Die getrennte Ausgestaltung der Werkzeuge ermöglicht es, jedem Werkzeug einen individuellen Schließdruck zuzuordnen. Der Schließdruck des Heizwerk- zeuges kann beispielsweise niedriger sein als der des Formwerkzeuges.The heating device and / or the perforating device can be implemented in separate, cyclically closing and opening tools, the tools imparting a closing pressure. Each tool is equipped with a closing device for supplying the closing pressure and an opening device for opening the tool, the closing device being a compression spring for generating the Includes closing pressure and the opening device is designed to open the mold against the closing pressure. The separate design of the tools makes it possible to assign an individual closing pressure to each tool. The closing pressure of the heating tool can, for example, be lower than that of the molding tool.
Das Komponententrägerband ist zum Zeitpunkt der Lochung üblicherweise noch nicht wieder vollständig erkaltet. Die verbleibende Restwärme kann zu Komplikationen beim Bilden des Kontrollloches führen. Das Aussparen desjenigen Bereiches des Rohbandes, in dem später das Kontrollloch gebildet werden wird, hilft diese Komplikationen zu vermeiden. Vorteilhaft ist es daher insbesondere, wenn die Heizvorrichtung derart ausgebildet ist, dass sie denjenigen Bereich des Rohbandes nicht heizt, der im fertigen Komponententrägerband den Bodenbereich der Komponententasche bildet, in den die Lochvorrichtung das Kontrollloch einbringt.The component carrier tape is usually not yet completely cold again at the time of the perforation. The remaining heat can lead to complications when forming the control hole. The omission of that area of the raw strip in which the control hole will be formed later helps to avoid these complications. It is therefore particularly advantageous if the heating device is designed such that it does not heat that area of the raw strip that forms the bottom area of the component pocket in the finished component carrier strip, into which the punching device makes the control hole.
Es ist vorteilhaft, wenn die Formvorrichtung eine Synchronisiereinrichtung zum Synchronisieren der Transporteinrichtung mit dem zyklischen Öffnen und Schließen des Formwerkzeuges, der Heizeinrichtung und der Lochvorrichtung aufweist, damit die Arbeitsabläufe der Formvorrich- tung möglichst synchron ablaufen.It is advantageous if the molding device has a synchronizing device for synchronizing the transport device with the cyclical opening and closing of the molding tool, the heating device and the punching device, so that the work processes of the molding device run as synchronously as possible.
Die Transporteinrichtung kann einen Antrieb zum Vermitteln eines schrittweisen Vortriebs an das Komponententrägerband bzw. das Rohband umfassen. In diesem Fall lässt sich die Synchronisiereinrichtung durch einen auf der Welle angeordneten Auslöser zu Auslösen der Vor- triebsschritte realisieren.The transport device can comprise a drive for imparting a gradual advance to the component carrier belt or the raw belt. In this case, the synchronizing device can be implemented by a trigger arranged on the shaft to trigger the advance steps.
In einer besonders bevorzugten Ausführungsvariante weist die Formvorrichtung eine Schneidvorrichtung auf, die dem Formwerkzeug ein Transportrichtung des Roh- bzw. Komponententrägerbandes nachgeordnet und ausgebildet ist, das geformte Komponententrägerband in Längsrichtung zu teilen. Das Formwerkzeug ist vorzugsweise ausgebil- det, wenigstens zwei bezüglich der Längsrichtung des Komponententrägerbandes seitlich nebeneinander angeordnete Komponententaschen in das Komponententrägerband zu formen, so dass auf dem Komponententrägerband wenigstens zwei nebeneinander angeordnete Reihen von Komponententaschen geschaffen werden. Vorzugsweise ist hierbei die Schneidvorrichtung relativ zum Formwerkzeug derart angeordnet, dass die Schneidvorrichtung das Komponententrägerband zwischen den nebeneinander geformten Komponententaschen in Längsrichtung teilt. Auf die Weise können aus einem Rohband mehrere Komponententräger- bänder hergestellt werden, so dass die Herstellung solcher Komponen- tenträgerbänder besonders schnell und effizient erfolgen kann.In a particularly preferred embodiment variant, the shaping device has a cutting device, which is arranged downstream of the shaping tool and a transport direction of the raw or component carrier tape and is designed to divide the shaped component carrier tape in the longitudinal direction. The molding tool is preferably designed det, at least two in the longitudinal direction of the component carrier tape side by side arranged component pockets into the component carrier band, so that at least two rows of component pockets arranged next to each other are created on the component carrier band. The cutting device is preferably arranged relative to the molding tool in such a way that the cutting device divides the component carrier tape in the longitudinal direction between the component pockets formed next to one another. In this way, several component carrier tapes can be produced from one raw strip, so that the production of such component carrier tapes can take place particularly quickly and efficiently.
Weitere Merkmale und Vorteile der Erfindung lassen sich den Unteransprüchen entnehmen und werden nachfolgend anhand eines detaillierten Ausführungsbeispiels unter Bezugnahme auf die beiliegenden Zeichnungen näher erläutert. Es zeigen:Further features and advantages of the invention can be found in the subclaims and are explained in more detail below on the basis of a detailed exemplary embodiment with reference to the accompanying drawings.

Figur 5 eine weitere perspektivische Ansicht der in Figur 4 gezeigten Ausführungsform. Anhand der Figuren 1a und 1b wird nun der Aufbau und die Funktion der erfindungsgemäßen Vorrichtung zum Formen eines Komponententrägerbandes 1 beschrieben. Die Vorrichtung umfasst ein Formwerkzeug 9 und eine Transporteinrichtung 5, 7 zum Transportieren des Komponen- tenträgerbandes 1. Die Transporteinrichtung 5, 7 kann beispielsweise ein Zahnrad mit Zähnen zum Eingriff in die Indexlöcher des Bandes (die Indexlöcher stellen eine Lochung in einem Seitenstreifen des Bandes dar) umfassen und kann gleichzeitig zum Führen des Bandes ausgelegt sein. Sie umfasst außerdem einen Motor, im Ausführungsbeispiel einen Servomotor (nicht dargestellt), der dem Band 1 einen schrittweisen Vortrieb vermittelt.Figure 5 is another perspective view of the embodiment shown in Figure 4. The structure and function of the device according to the invention for forming a component carrier tape 1 will now be described with reference to FIGS. 1a and 1b. The device comprises a molding tool 9 and a transport device 5, 7 for transporting the component carrier tape 1. The transport device 5, 7 can, for example, be a toothed wheel with teeth for engagement in the index holes of the tape (the index holes represent a perforation in a side strip of the tape ) include and can be designed to guide the tape at the same time. It also includes a motor, in the exemplary embodiment a servo motor (not shown), which provides the belt 1 with a gradual advance.
Das Formwerkzeug 9 umfasst zwei Halbteile 36, 38 mit einen Stempel 17 und einer Matrize 19, zwischen denen das Komponententrägerband 1 hindurch geführt ist. Den Vorschub des Komponententrägerbandes 1 vermittelt die Transporteinrichtung 5, 7. Zum Ausformen der Komponententaschen 3, die ebenfalls im Schnitt dargestellt sind, wird dieses Formwerkzeug 9 geschlossen (Figur 1b), sobald sich ein Abschnitt des Rohbandes 2, in dem die Komponententaschen 3 ausgeformt werden sollen, zwischen dem Stempel 17 und der Matrize 19 befindet.The molding tool 9 comprises two half parts 36, 38 with a punch 17 and a die 19, between which the component carrier tape 1 is passed. The feed device 5, 7 feeds the component carrier belt 1. To form the component pockets 3, which are also shown in section, this molding tool 9 is closed (FIG. 1b) as soon as there is a section of the raw belt 2 in which the component pockets 3 are formed are located between the stamp 17 and the die 19.
Sowohl Stempel 17 als auch Matrize 19 sind beweglich gelagert und werden durch je eine Öffnungs- und Schließeinrichtung 40, 42 während des Herstellungsprozesses in Richtung des Rohbandes 2 bewegt bzw. vom Rohband 2 wieder weggefahren. Die Bewegung der beiden Komponenten des Formwerkzeugs 9 ist dabei so aufeinander abgestimmt, dass das Rohband 2 nicht aus seiner Transportebene herausgedrückt wird.Both the punch 17 and the die 19 are movably supported and are moved in the direction of the raw strip 2 or moved away from the raw strip 2 by an opening and closing device 40, 42 during the manufacturing process. The movement of the two components of the molding tool 9 is coordinated with one another in such a way that the raw strip 2 is not pressed out of its transport plane.
Ein umlaufender Rand 44 der Matrize 19 liegt im geschlossenen Zustand des Formwerkzeugs 9 an einer Oberseite des Rohbandes 2 an und legt damit die Bereiche des Rohbandes 2 fest, die beim Formvor- gang nicht gedehnt werden sollen. Eine Gegenaufnahme bildet eine auf einer Werkplatte 46 der Formvorrichtung aufgebrachte Fixierplatte 48. Auf der der Werkplatte 46 zugewandten Seite der Fixierplatte 48 sind in geeigneten Aussparungen der beiden Teile Federelemente 50 angeordnet. Die Federelemente gewähren ein Spiel von ca. 0,2 bis 0,3 mm zwischen der Werkplatte 46 und der Fixierplatte 48. Das geringe Spiel der Federelemente 50 erlaubt es Dickenunterschiede im Rohband 2 zu kompensieren und führt zu einer gleichmäßigeren Verteilung der ansetzenden Druckkräfte. Werkplatte 46 und Fixierplatte 48 weisen eine Ausschnittsöffnung auf, durch die der Stempel 17 hindurchtreten kann.In the closed state of the molding tool 9, a peripheral edge 44 of the die 19 lies against an upper side of the raw strip 2 and thus defines the regions of the raw strip 2 which are not to be stretched during the molding process. A counter-receptacle is formed by a fixing plate 48 applied to a work plate 46 of the molding device. On the side of the fixing plate 48 facing the work plate 46, spring elements 50 are arranged in suitable cutouts in the two parts. The spring elements allow a play of approx. 0.2 to 0.3 mm between the work plate 46 and the fixing plate 48. The small play of the spring elements 50 allows differences in thickness in the raw strip 2 to be compensated for and leads to a more even distribution of the compressive forces that are applied. Work plate 46 and fixing plate 48 have a cutout opening through which the stamp 17 can pass.
Figur 2a zeigt eine Seitenansicht der Formvorrichtung im Bereich des Formwerkzeugs 9 in einer speziellen Ausführungsform, bei der zur Vereinfachung auf die Darstellung der Werkplatte 46 bzw. der Fixierplatte 48 verzichtet wurde. Das Schließen des Formwerkzeuges 9 wird durch je eine mit dem Stempel 17 und der Matrize 19 verbundene Pneumatikfeder bewerkstelligt, die jeweils einen mit Pressluft beaufschlagten Pressluftbalg 11.1, 11.2 umfassen. Die Pressluftbälge 11.1, 11.2 sind also Teil der Schließeinrichtung des Formwerkzeugs 9. Mittels einer in den Figuren nicht dargestellten Einsteilvorrichtung lässt sich der Druck der Pressluft in den Bälgen 11.1 , 11.2 variieren und somit die Federkraft der von den Pressluftbälgen 11.1 , 11.2 gebildeten Druckluftfeder einstel- len. Dies kann zum Beispiel sinnvoll sein, wenn Rohbänder 2 mit verschiedenen Banddicken verwendet werden. Gemäß DIN-Norm IEC 286 III sind Banddicken zwischen 0,3 und 0,6 mm möglich.FIG. 2a shows a side view of the molding device in the area of the molding tool 9 in a special embodiment, in which, for simplicity, the representation of the work plate 46 or the fixing plate 48 has been omitted. The mold 9 is closed by a pneumatic spring connected to the plunger 17 and the die 19, each of which comprises a compressed air bellows 11.1, 11.2 loaded with compressed air. The compressed air bellows 11.1, 11.2 are therefore part of the closing device of the molding tool 9. By means of an adjusting device (not shown in the figures), the pressure of the compressed air in the bellows 11.1, 11.2 can be varied and thus the spring force of the compressed air spring formed by the compressed air bellows 11.1, 11.2 can be set. len. This can be useful, for example, if raw strips 2 with different strip thicknesses are used. According to DIN standard IEC 286 III, strip thicknesses between 0.3 and 0.6 mm are possible.
Zum Öffnen des Formwerkzeuges 9 gegen die von den Pressluftbälgen 11.1 , 11.2 erzeugte Schließkraft sind der Stempel 17 und die Matrize 19 über zwei Hebel 25 und ein Gelenk 27 gelenkig miteinander verbunden (Figur 2a). Zwischen den Hebeln 25 befindet sich eine auf einer Welle 15 angeordnete und von dieser angetriebene Kurvenscheibe 13. Die Umfangsfläche der Kurvenscheibe 13 besitzt beispielsweise eine elliptische Form. Die Welle 15, auf der die Kurvenscheibe 13 angeordnet ist, wird von einem Drehstrommotor mit regelbarer Drehzahl angetrieben, so dass die Kurvenscheibe 13 mit einer bestimmten Frequenz rotiert. Dabei werden die Hebel 25 immer durch die Druckkraft der Pressluftbälge 11.1 , 11.2 gegen die Umfangsfläche der Kurvenscheibe 13 gepresst. Aus der Rotation der Kurvenscheibe 13 resultiert daher eine zangenför- mige sich öffnende und schließende Bewegung des Formwerkzeuges 9, wobei die größte Öffnung des Formwerkzeuges 9, d. h. die größte Spreizung der Hebel 25, durch die große Halbachse der Ellipse gegeben ist und die geringste Öffnung durch die kleine Halbachse. Die ellipsen- förmige Form der Kurvenscheibe 13 ist hier lediglich zur Vereinfachung der Darstellung gewählt. Es versteht sich, dass die Form der Umfangs- fläche der Kurvenscheibe 13 je nach tatsächlichem Bewegungsablauf verschieden gewählt sein kann. Außerdem ist es möglich, statt einer gemeinsamen Kurvenscheibe 13 für beide Hebel 25 jeweils eine eigene Kurvenscheibe vorzusehen. Dies erschwert aber die Koordination der Bewegungsabläufe.To open the mold 9 against the closing force generated by the compressed air bellows 11.1, 11.2, the punch 17 and the die 19 are connected to one another in an articulated manner via two levers 25 and a joint 27 (FIG. 2a). Between the levers 25 there is a cam disk 13 which is arranged on a shaft 15 and is driven by it. The circumferential surface of the cam disk 13 has, for example, an elliptical shape. The shaft 15, on which the cam plate 13 is arranged, is driven by a three-phase motor with adjustable speed, so that the cam plate 13 rotates at a certain frequency. there the levers 25 are always pressed against the circumferential surface of the cam plate 13 by the pressure force of the compressed air bellows 11.1, 11.2. The rotation of the cam disc 13 therefore results in a pincer-shaped opening and closing movement of the molding tool 9, the largest opening of the molding tool 9, ie the greatest spread of the levers 25, being given by the large semiaxis of the ellipse and the smallest opening being the small semi-axis. The elliptical shape of the cam plate 13 is chosen here only to simplify the illustration. It goes without saying that the shape of the circumferential surface of the cam disk 13 can be selected differently depending on the actual movement sequence. In addition, it is possible to provide a separate cam disk for each lever 25 instead of a common cam disk 13. However, this complicates the coordination of the movements.
Zum Warten des Formwerkzeuges 9 oder zum Auswechseln der Matrize 19 oder des Stempels 17 können die Bälge 11.1 , 11.2 beispielsweise über die Einsteilvorrichtung zum Einstellen des Luftdrucks oder über eine eigens vorgesehene Entlüftungseinrichtung entlüftet werden. Nach dem Entlüften der Bälge 11.1 , 11.2 könne die Hebel 25 ohne großen Kraftaufwand von der Kurvenscheibel 3 abgehoben werden.To maintain the mold 9 or to replace the die 19 or the stamp 17, the bellows 11.1, 11.2 can be vented, for example, via the adjusting device for adjusting the air pressure or via a specially provided venting device. After the bellows 11.1, 11.2 have been vented, the lever 25 can be lifted off the cam disk 3 without great effort.
Das vom Gelenk 27 entfernte Ende des Hebel 25, und damit die an diesem Ende fixierte Matrize 19 bzw. der an diesem Ende fixierte Stempel 17, führen im Betrieb eine Bewegung aus, die auf eine Kreisbahn liegt. Um den Stempel 17 und die Matrize 19 eine geradlinige Bewegung aus- führen zu lassen, ist in der in Figur 2b dargestellten alternativen Ausführungsform eine Geradeführung vorgesehen. Diese umfasst eine gerade Führungsstange 10, von der die Matrize 19 und der Stempel 17 linear geführt sind. Außerdem ist im Bereich des vom Gelenk entfernten Endes des Hebels 25 sowie im Bereich der Matrize 19 jeweils ein Gelenk 14, 16 vorhanden, zwischen denen sich eine kurze Stange befindet, um die kreisförmige Bewegung des Hebelendes auszugleichen. Zu dem glei- - lo ¬The end of the lever 25 remote from the joint 27, and thus the die 19 fixed at this end or the punch 17 fixed at this end, perform a movement in operation which lies on a circular path. In order to have the punch 17 and the die 19 perform a linear movement, a straight guide is provided in the alternative embodiment shown in FIG. 2b. This comprises a straight guide rod 10, of which the die 19 and the punch 17 are guided linearly. In addition, in the region of the end of the lever 25 remote from the joint and in the region of the die 19 there is a joint 14, 16 between which there is a short rod in order to compensate for the circular movement of the lever end. To the same - lo ¬
chen Zweck ist am Stempel 17 ebenfalls ein Gelenk 14 vorhanden, dass über eine Stange gelenkig mit dem Hebel 25 verbunden ist.Chen purpose, there is also a joint 14 on the punch 17, which is articulated to the lever 25 via a rod.
Eine alternative Ausführungsform der Vorrichtung zum Formen von Komponententrägerband 1 ist in Figur 3 dargestellt. Die in Figur 3 dar- gestellte Vorrichtung umfasst außer dem Formwerkzeug 9 noch eine Heizvorrichtung 21, mit der das Rohband 2 erwärmt wird, bevor es dem Formwerkzeug 9 zugeführt wird. Dem Formwerkzeug 9 nachgeordnet ist eine Lochvorrichtung 23, mit der in die Böden der ausgeformten Komponententaschen 3 Löcher eingebracht werden, durch die später beim Befüllen oder Entleeren der Komponententaschen 3 der Füllzustand der Tasche bestimmt werden kann.An alternative embodiment of the device for forming component carrier tape 1 is shown in FIG. In addition to the molding tool 9, the device shown in FIG. 3 also comprises a heating device 21 with which the raw strip 2 is heated before it is fed to the molding tool 9. Downstream of the molding tool 9 is a hole device 23 with which 3 holes are made in the bottoms of the molded component pockets, through which the filling state of the pocket can be determined later when the component pockets 3 are filled or emptied.
Sowohl die Heizvorrichtung 21 als auch die Lochvorrichtung 23 sind wie das Formwerkzeug 9 so ausgestaltet, dass sie einen Zyklus aus Öffnen und Schließen durchlaufen. Es ist eine Synchronisiereinrichtung (nicht dargestellt) vorhanden, die die Zyklen der Heizvorrichtung 21, des Formwerkzeugs 9 und der Lochvorrichtung 23 derart mit dem Transport des Bandes 2 durch die Transporteinrichtung 5, 7 synchronisiert, dass das Band 2 dann weitertransportiert wird, wenn die Heizvorrichtung 21 , das Formwerkzeugs 9 und die Lochvorrichtung 23 geöffnet sind. Die Synchronisiereinrichtung ist auch vorhanden, wenn die Formvorrichtung lediglich mit einem Formwerkzeug 9 aber nicht mit einer Heizvorrichtung 21 oder Lochvorrichtung 23 ausgestattet ist.Both the heating device 21 and the perforating device 23, like the molding tool 9, are designed such that they go through a cycle of opening and closing. There is a synchronizing device (not shown) which synchronizes the cycles of the heating device 21, the molding tool 9 and the punching device 23 with the transport of the band 2 through the transport device 5, 7 in such a way that the band 2 is transported further when the heating device 21, the mold 9 and the punch device 23 are open. The synchronizing device is also present if the molding device is only equipped with a molding tool 9 but not with a heating device 21 or perforating device 23.
Die Synchronisation des Formwerkzeugs 9 mit der Heizvorrichtung 21 und der Lochvorrichtung 23 ist dadurch gegeben, dass die ihnen zuge- ordneten Kurvenscheiben auf einer gemeinsamen Welle 15 angeordnet sind.The synchronization of the molding tool 9 with the heating device 21 and the punching device 23 is provided in that the cam disks assigned to them are arranged on a common shaft 15.
Das Öffnen und Schließen der Heizvorrichtung 21 und der Lochvorrichtung 23 erfolgt auf die gleiche Weise wie das Öffnen und Schließen des Formwerkzeuges 9. Dabei kann jedoch die von den Pressluftbälgen 11 erzeugte Schließkraft geringer sein als die der Pressluftbälge 11.1, 11.2 des Formwerkzeugs 9. Insbesondere die Heizvorrichtung 21 benötigt keine hohe Schließkraft. Das Einstellen der Schließkraft erfolgt bei der Heizvorrichtung 21 und der Lochvorrichtung 23 wie beim Formwerkzeug 9 durch das Einstellen der Pressluft, mit der der Pressluftbalg 11 beauf- schlagt wird. Dazu ist eine Einstellvorrichtung (nicht dargestellt) vorgesehen, mit der sich der Pressluftdruck jedes Balges 11 individuell einstellen lässt.The opening and closing of the heating device 21 and the punching device 23 is carried out in the same way as the opening and closing of the molding tool 9. However, the closing force generated by the compressed air bellows 11 can be lower than that of the compressed air bellows 11.1, 11.2 of the molding tool 9. In particular, the heating device 21 does not require a high closing force. In the heating device 21 and the punching device 23, the closing force is adjusted, as in the mold 9, by adjusting the compressed air with which the compressed air bellows 11 is acted upon. For this purpose, an adjusting device (not shown) is provided, with which the compressed air pressure of each bellows 11 can be adjusted individually.
Ein weiteres Ausführungsbeispiel für die erfindungsgemäße Vorrichtung ist in den Figuren 4 und 5 gezeigt. Die darin gezeigte Vorrichtung ist mit einem Formwerkzeug 9, einer Heizvorrichtung 21 und einer Lochvorrichtung 23 ausgestattet. Entsprechend sind in Figur 4 drei Paare aus Hebeln 25 zu erkennen, die jeweils über zwei Gelenke 27a, 27b und eine Verbindungsstange 28 miteinander verbunden sind. An den von den Gelenken 27a und 27b entfernten Enden der Hebel 25 sind Grundplat- ten 12, 12' für die Bälge 11.1 , 11.2, 11 vorhanden. Die Grundplatte 12' hat einen geringeren Durchmesser als die Grundplatte 12, da sie der Heizvorrichtung 21 zugeordnet ist. Die Heizvorrichtung 21 benötigt jedoch nur eine geringere Schließkraft als das Formwerkzeug 9. Deswegen brauchen die Bälge 11 für die Heizvorrichtung 21 nur eine geringere maximale Schließkraft aufzubringen, als die Bälge 11.1, 11.2 für das Formwerkzeug 9. Entsprechend können sie gegenüber den Bälgen 11.1, 11.2 für das Formwerkzeug 9 geringere Abmessungen aufweisen.Another exemplary embodiment of the device according to the invention is shown in FIGS. 4 and 5. The device shown therein is equipped with a molding tool 9, a heating device 21 and a punching device 23. Accordingly, three pairs of levers 25 can be seen in FIG. 4, each of which is connected to one another via two joints 27a, 27b and a connecting rod 28. Base plates 12, 12 'for the bellows 11.1, 11.2, 11 are provided at the ends of the levers 25 remote from the joints 27a and 27b. The base plate 12 ′ has a smaller diameter than the base plate 12 because it is assigned to the heating device 21. However, the heating device 21 only requires a lower closing force than the molding tool 9. Therefore, the bellows 11 for the heating device 21 only need to apply a lower maximum closing force than the bellows 11.1, 11.2 for the molding tool 9. Accordingly, they can be compared to the bellows 11.1, 11.2 have smaller dimensions for the molding tool 9.
Zum Öffnen der Hebel 25 sind jedem Hebelpaar 27a, 27b zwei Kurvenscheiben 13a und 13b zugeordnet, jeweils eine für pro Hebel. Die Kur- venscheiben werden durch eine Welle 15 angetrieben, die wiederum vom Drehstrommotor 30 angetrieben wird. Auf der Welle 15 ist ein Auslöser in Form eines Stiftes (nicht dargestellt) angeordnet, der, wenn er sich an einem Signalaufnehmer (ebenfalls nicht dargestellt) vorbei bewegt, ein Signal für die Synchronisationseinrichtung zum Synchronisie- ren der Bandtransports mit der Bewegung des Formwerkzeugs 9, der Heiz- 21 sowie der Lochvorrichtung 23 erzeugt. Als Teil der Transporteinrichtung ist in Figur 4 die Walzenkombination 5' zu erkennen.To open the levers 25, two cam plates 13a and 13b are assigned to each pair of levers 27a, 27b, one for each lever. The cam disks are driven by a shaft 15, which in turn is driven by the three-phase motor 30. A trigger in the form of a pin (not shown) is arranged on the shaft 15 and, when it moves past a signal pickup (also not shown), a signal for the synchronization device for synchronizing the belt transport with the movement of the molding tool 9 , the Heating 21 and the hole device 23 generated. The roller combination 5 'can be seen in FIG. 4 as part of the transport device.
Figur 5 zeigt eine perspektivische Vorderansicht der Maschine aus Figur 4. Vom Formwerkzeug 9, der Heizvorrichtung 21 und der Lochvorrich- tung 23 sind in Figur 5 lediglich die Halteplatten zum Befestigen der entsprechenden Werkzeuge dargestellt.FIG. 5 shows a perspective front view of the machine from FIG. 4. Of the shaping tool 9, the heating device 21 and the hole device 23, only the holding plates for fastening the corresponding tools are shown in FIG.
In Figur 5 sind zu erkennen: die Gelenke 14 und 16 sowie die Führungsstangen 10 der Geradeführung des Formwerkzeuges 9, der Heizvorrichtung 21 und der Lochvorrichtung 23, außerdem die Walzenkombination 5' und ein Vortriebsrad 7' der Antriebseinrichtung zum Antreiben des Bandes. Zum Antreiben des Vortriebsrades 7' kann beispielsweise ein Servomotor vorgesehen sein. Ebenfalls zu erkennen ist eine Prüfvorrichtung 31 , die die fertigen Komponententaschen auf Fehler prüft. In Figure 5 can be seen: the joints 14 and 16 and the guide rods 10 of the straight guide of the mold 9, the heating device 21 and the punching device 23, also the roller combination 5 'and a driving wheel 7' of the drive device for driving the belt. For example, a servo motor can be provided to drive the driving wheel 7 '. A test device 31 can also be seen, which checks the finished component pockets for defects.
