Definitions
- the invention relates to a method for transporting a sequence of small-parts containers in a warehouse under a horizontal removal opening of an assembly table, in particular for printed circuit boards.
- DE 31 14 032 C2 discloses a method for transporting a sequence of small parts containers to a removal opening, in which a bearing located below the working level of the assembly table is moved in such a way that the small parts container contains the small parts required for processing comes to lie below the removal opening.
- the containers are arranged in a fixed order when they are brought in, so that very short access times are only possible if small parts that are required one after the other are accommodated in adjacent containers.
- Another known method for transporting small parts containers (brochure from ROYONIC, RHS D 851 A 11/83), which is used in an assembly table with a storage area with small parts containers running around in its rear area.
- the object of the invention is to create a method for transporting a sequence of small-parts containers to a removal opening, with which very short delivery times for successive containers can be achieved largely independently of the spatial arrangement of the small-parts containers in a warehouse permit.
- the invention solves this problem based on the method defined above in that at least one of the small parts containers in the warehouse is determined by a program control according to a request, that an access element of a loading and unloading device and the warehouse are moved relative to each other and thereby the access organ is guided to the parking space of the specific small parts container, that this container is removed from the warehouse and moved with the loading and unloading device and a transport arrangement with at least two transport tracks to the removal opening, that after removal of a predetermined number of small parts of the containers via the transport arrangement and the loading and unloading device to an empty parking space in the warehouse selected by the program control and this position is stored.
- a major advantage of the method is that because of the loading and unloading device and the transport arrangement formed, divided transport path from the warehouse to the removal opening, the transport arrangement can be utilized as a buffer by, for example, during movement in the transport arrangement and des necessary dwelling of a small parts container under the removal opening at least one further, subsequently required small parts container is conveyed by means of the loading and unloading device to the transport arrangement.
- the design of the transport arrangement can be varied according to the desired working method.
- the supply and removal of the small parts containers to and from the removal opening can take place from one or more sides as well as on several levels. If it is useful to shorten the transport time, each transport track can be used alternately in one or both directions as required. However, it is to be regarded as particularly advantageous that each small parts container (6) is brought back to the removal opening (8) via a transport track (9a) and to the loading and unloading device (10) via a transport track (9b).
- a certain number of empty parking spaces in the warehouse makes it easier for the program control to shorten the route taken by the access organ. For example, a small-parts container that is no longer needed is taken to an empty parking space that is as close as possible to the storage space for the next container to be fetched.
- the arrangement for carrying out the method is characterized in that the mounting table with removal opening is immediately adjacent to the warehouse, that the access element of the loading and unloading device can be guided to any parking space and to the transport arrangement, that the transport arrangement between removal opening and loading and Unloading device is located and that the program control of the loading and unloading device and the transport arrangement is assigned.
- Such an arrangement offers the advantage of very short transport routes or deployment times.
- the time that Access organ needed to reach a specific parking space can be further shortened if the bearing is movable - especially linearly be ⁇ movable in the horizontal direction - is. Thus, it can be moved towards the access organ, for example, halfway.
- the transport arrangement is designed in such a way that it lies outside the area of the printed circuit board to be assembled, the ergonomically favorable arrangement of a horizontal removal opening in the immediate vicinity of the printed circuit board to be assembled can be achieved with a program-controlled cutting and bending tool be combined.
- a loading and unloading device and at least one transport track are assigned to each sub-storage facility.
- a connecting device between the stores in order to prevent the occurrence of an overcrowding of an individual part store and not to disturb the work process at the removal opening.
- This connecting device is preferably equipped with a drivable conveyor device.
- Each transport arrangement preferably contains a transport device which corresponds to at least one transport track.
- a horizontally circulating conveyor belt is chosen to connect the supply position and the removal opening, this conveyor belt can both feed and remove small parts containers.
- a single transport device thus corresponds to two transport tracks, as a result of which the transport arrangement is mechanically simplified.
- the degree of automation of the arrangement for carrying out the method according to the invention can be further increased if empty small parts containers are detected by means of weighing devices; Using the program control, the empty containers can then be replaced with full ones when using an automatic loading system.
- FIG. 1 shows a perspective view of a first arrangement for carrying out the method according to the invention
- FIG. 2 shows the outline of a second arrangement for carrying out the method according to the invention
- FIG. 3 shows the top view of the second arrangement.
- FIG. 1 represents a Be Services ⁇ place for printed circuit boards 1. They are fed into stacking containers 2 via a conveyor 3 and a stack lift 4. An operator removes the printed circuit board 1 and places it in the working position of the mounting table 5.
- the components are located located in small parts containers 6, which are taken below the working level from a warehouse 7 to a Ent ⁇ opening 8 of the placement table 5.
- the small-parts containers 6 are fed in via an upper transport track 9a and removed via a lower transport track 9b.
- the small parts container 6 required in each case is determined by a program control which controls a loading and unloading device 10 to its position in the warehouse 7 .
- the loading and unloading device 10 consists of two linearly movable parts, the horizontal part 10a and the vertical part 10b.
- the vertical part 10b contains two access organs, the. are assigned to both transport paths 9a, 9b.
- the upper access organ now removes the container 6 determined by the program control from the store.
- the loading and unloading device 10 a provision ment position approached at which the small parts container 6 is transferred to the transport path 9a.
- the lower access element takes over a small parts container 6 from the lower transport track 9b in order to bring it back to the store 7. While the upper transport track 9a brings the small parts container 6 that has just been brought to the removal opening 8, the loading and unloading device 10 fetches the next one and brings the one that is no longer required to an empty storage space in the warehouse 7.
- the position of the parked container 6, which is new in most cases, is saved.
- the delivery time specified by the operation of the loading and unloading device 10 is on average shorter than the time required by the operator of the loading table 5 for the loading of a printed circuit board 1 with the components from a container 6. This makes it possible to use several Line up small parts container 6 on the transport path 9a. Thus the loading time of the operator is not lengthened by the preparation time for the small parts container 6 .
- a monitor 11 informs the operator of the number of small parts to be removed. To do this, it takes about three seconds on average and can then use the foot switch 12 to replace the small parts container 6 . This results in an average availability time for the loading and unloading device 10 of less than three seconds.
- a luminous pointer 13 which is also guided by the program control, indicates to the operator the position of the small parts on the printed circuit board 1 to be fitted. Below the printed circuit board 1 there is a cutting and bending tool (not shown). This shortens the connecting wires of the small parts and bends them so that they do not come out of the solder bath during the onward transport of the printed circuit board 1 PCB 1 can fall. Since the printed circuit boards 1 have different sizes, 14 mask inserts are stored on a shelf for adaptation.
- Empty small parts containers 6 can be detected by a weighing device, for example in the vertical part 10b.
- the program control then regulates the exchange of empty containers 6 for full ones with the aid of an external loading system. This exchange takes place via the side of the bearing 7 facing away from the mounting table 5.
- simpler solutions to this problem are also conceivable. If, for example, the original number of small parts in a container 6 is stored in the program control, then by subtracting the number of small parts removed, the program control can determine the time for filling the corresponding container 6 .
- Two assembly tables can also be arranged on the same side of a shared warehouse. With correspondingly rapid movements of the loading and unloading device 10, it can be used to supply both placement tables—preferably arranged opposite one another.
- the second exemplary embodiment shown in FIGS. 2 and 3 differs from the first essentially by a two-part store 7a, 7b and a transport arrangement which further shortens the availability times of the individual small parts containers 6 due to flexible operation.
- Each of the two sub-warehouses 7a, 7b has its own loading and unloading device 10--shown only for sub-warehouse 7a--assigned to one access organ each.
- the transport arrangement consists of two transport paths 9, which lead to the removal opening 8 from two opposite sides. The special feature of this arrangement is that now each of the two transport paths 9 small parts container 6 can supply or discharge, either independently or in combination.
- the program control determines the direction of transport depending on whether small parts containers 6 have to be fetched from the right part store 7b or the left part store 7a. If a small parts container 6 is brought under the removal opening 8 from the left, for example, it is advantageous to transport it away to the right if the next one also comes from the left. However, if the next one is already on the right, the small parts container 6 must be moved to an empty parking space on the left. In order to be able to maintain this working method with only a slight oversupply of empty parking spaces, an additional connecting device 15 is required. This ensures compensation by enabling small parts containers 6 to be moved from one sub-storage facility 7a or 7b directly to the other transport animals.
- the small-parts containers 6 can be returned to any empty parking space, and their position is also stored by the program control.
- the removal opening 8 is twice as long and is provided with a sliding cover. From two sides, the small-parts containers 6 are supplied from two part stores 7a, 7b via two transport tracks 9a, 9b each, as well as removed. The part of the removal opening 8 required in each case is released by the sliding cover.
- the transport arrangement and the connector 15, devices can be used in the exemplary embodiments, as shown in the prospectus "Modular Handling System” from Siemens, MCH 01810.8310.
- the loading and unloading devices 10 can consist, for example, of so-called “gantry loaders”, such as she shows on page 3.
- the transport tracks 9, 9a, 9b of the transport arrangement and the connecting device 15 can be "portal axes" according to page 6. It is also by no means mandatory to arrange the bearing 7, 7a, 7b in a linear manner.
- a rotatable and pivotable arm as the loading and unloading device 10 it is also possible to set it up along part of an arc of a circle.
- Assembly tables according to the invention are particularly suitable for assembling small series of printed circuit boards and for repairing and replenishing automatically processed printed circuit boards.

Description
Verfahren zum Transportieren von Kleinteile-Behältern unter eine Entnahmeöffnung eines BestücktischesMethod for transporting small parts containers under a removal opening of an assembly table
Die Erfindung betrifft ein Verfahren zum Transportieren einer Abfolge von Kleinteile-Behältern eines Lagers unter eine horizontale Entnahmeöffnung eines Bestücktisches, ins¬ besondere für Leiterplatten.The invention relates to a method for transporting a sequence of small-parts containers in a warehouse under a horizontal removal opening of an assembly table, in particular for printed circuit boards.
Trotz der immer weiteren Verbreitung von Bestückungsautoma¬ ten für Leiterplatten sind manuelle Bestücktische immer noch von Bedeutung. Einerseits sind gewisse Bauteile aufgrund ihrer Form und Größe nach wie vor nicht vollautomatisch ver¬ arbeitbar, andererseits ist manuelle Bestückung bei kleinen Serien rationeller als automatische. Auch der Austausch ein¬ zelner, fehlerhafter Bauteile, die bei der Fertigungskon- trolle entdeckt werden, erfolgt zumeist manuell.Despite the increasing spread of automatic placement machines for printed circuit boards, manual placement tables are still important. On the one hand, certain components still cannot be processed fully automatically due to their shape and size, on the other hand, manual assembly is more efficient than automatic for small series. The replacement of individual faulty components, which are discovered during production control, is mostly done manually.
Der DE 31 14 032 C2 ist ein Verfahren zum Transportieren einer Abfolge von Kleinteile-Behältern zu einer Entnahme¬ öffnung entnehmbar, bei dem ein unterhalb der Arbeitsebene des Bestückungstisches befindliches Lager so bewegt wird, daß der Kleinteile-Behälter mit den jeweils zur Verarbeitung benötigten Kleinteilen unterhalb der Entnahmeöffnung zu lie¬ gen kommt. In dem beweglichen Lager sind die Behälter mit ihrem Einbringen in einer festen Reihenfolge angeordnet, so daß sehr kurze Zugriffszeiten nur dann möglich sind, wenn nacheinander benötigte Kleinteile in benachbarten Behältern untergebracht sind. Entsprechendes gilt für ein anderes bekanntes Verfahren zum Transportieren von Kleinteile-Behältern (Prospekt der Firma ROYONIC, RHS D 851 A 11/83), das bei einem Bestücktisch mit einem in seinem hinteren Bereich umlaufenden Lager mit Kleinteile-Behältern angewendet wird.DE 31 14 032 C2 discloses a method for transporting a sequence of small parts containers to a removal opening, in which a bearing located below the working level of the assembly table is moved in such a way that the small parts container contains the small parts required for processing comes to lie below the removal opening. In the movable store, the containers are arranged in a fixed order when they are brought in, so that very short access times are only possible if small parts that are required one after the other are accommodated in adjacent containers. The same applies to another known method for transporting small parts containers (brochure from ROYONIC, RHS D 851 A 11/83), which is used in an assembly table with a storage area with small parts containers running around in its rear area.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Transportieren einer Abfolge von Kleinteile-Behältern zu einer Entnahmeöffnung zu schaffen, mit dem sich, weitgehend unabhängig von der räumlichen Einordnung der Kleinteile-Be¬ hälter in einem Lager, sehr kurze Bereitstellungszeiten für aufeinanderfolgende Behälter erzielen lassen.The object of the invention is to create a method for transporting a sequence of small-parts containers to a removal opening, with which very short delivery times for successive containers can be achieved largely independently of the spatial arrangement of the small-parts containers in a warehouse permit.
Die Erfindung löst diese Aufgabe ausgehend von dem eingangs definierten Verfahren dadurch, daß jeweils mindestens einer der im Lager befindlichen Kleinteile-Behälter von einer Programmsteuerung einer Anforderung entsprechend bestimmt wird, daß ein Zugriffsorgan einer Be- und En'tladeeinrichtung und das Lager relativ zueinander bewegt werden und dadurch das Zugriffsorgan zum Abstellplatz des bestimmten Kleinteile- Behälters geführt wird, daß dieser Behälter dem Lager ent¬ nommen und mit der Be- und Entladeeinrichtung, sowie einer Transportanordnung mit mindestens zwei Transportbahnen zur Entnahmeöffnung bewegt wird, daß nach Entnahme einer vorbe- stimmten Anzahl von Kleinteilen der Behälter über die Transportanordnung und die Be-und Entladeeinrichtung zu einem leeren, von der Programmsteuerung ausgewählten Abstell¬ platz im Lager gebracht und diese Position gespeichert wird.The invention solves this problem based on the method defined above in that at least one of the small parts containers in the warehouse is determined by a program control according to a request, that an access element of a loading and unloading device and the warehouse are moved relative to each other and thereby the access organ is guided to the parking space of the specific small parts container, that this container is removed from the warehouse and moved with the loading and unloading device and a transport arrangement with at least two transport tracks to the removal opening, that after removal of a predetermined number of small parts of the containers via the transport arrangement and the loading and unloading device to an empty parking space in the warehouse selected by the program control and this position is stored.
Ein wesentlicher Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß aufgrund des von der Be- und Entladeein¬ richtung und der Transportanordnung gebildeten, unterteilten Transportweges vom Lager zur Entnahmeöffnung die Transport¬ anordnung als Puffer ausgenutzt werden kann, indem beispiels- weise während der Bewegung in der Transportanordnung und des notwendigen Verweilens eines Kleinteile-Behälters unter der Entnahmeöffnung mindestens ein weiterer, anschließend be¬ nötigter Kleinteile-Behälter mittels der Be- und Entlade¬ einrichtung zur Transportanordnung befördert wird.A major advantage of the method is that because of the loading and unloading device and the transport arrangement formed, divided transport path from the warehouse to the removal opening, the transport arrangement can be utilized as a buffer by, for example, during movement in the transport arrangement and des necessary dwelling of a small parts container under the removal opening at least one further, subsequently required small parts container is conveyed by means of the loading and unloading device to the transport arrangement.
Die Ausgestaltung der Transportanordnung ist entsprechend dem gewünschten Arbeitsverfahren variierbar. Die Zu- und Abfuhr der Kleinteile-Behälter zur und von der Entnahmeöff¬ nung kann von einer oder mehreren Seiten ebenso wie in mehreren Ebenen erfolgen. Wenn es der Verkürzung der Trans¬ portzeit dienlich ist, kann jede Transportbahn nach Bedarf in einer oder beiden Richtungen abwechselnd genutzt werden. Als besonders vorteilhaft ist jedoch anzusehen, daß jeder Kleinteile-Behälter (6) über eine Transportbahn (9a) zu der Entnahmeöffnung (8) und über eine Transportbahn (9b) zur Be- und Entladeeinrichtung (10) zurückgebracht wird.The design of the transport arrangement can be varied according to the desired working method. The supply and removal of the small parts containers to and from the removal opening can take place from one or more sides as well as on several levels. If it is useful to shorten the transport time, each transport track can be used alternately in one or both directions as required. However, it is to be regarded as particularly advantageous that each small parts container (6) is brought back to the removal opening (8) via a transport track (9a) and to the loading and unloading device (10) via a transport track (9b).
Eine gewisse Zahl von leeren Abstellplätzen im Lager erleich¬ tert es der Programmsteuerung, den Fahrtweg des Zugriffs- organs zu verkürzen. Beispielsweise wird ein nicht mehr benötigter Kleinteile-Behälter zu einem leeren Abstellplatz gebracht, der dem Lagerplatz des nächsten zu holenden Be¬ hälters möglichst naheliegt.A certain number of empty parking spaces in the warehouse makes it easier for the program control to shorten the route taken by the access organ. For example, a small-parts container that is no longer needed is taken to an empty parking space that is as close as possible to the storage space for the next container to be fetched.
Die Anordnung zur Durchführung des Verfahrens ist dadurch gekennzeichnet, daß dem Bestücktisch mit Entnahmeöffnung das Lager unmittelbar benachbart ist, daß das Zugriffsorgan der Be- und Entladeeinrichtung zu jedem beliebigen Abstellplatz und zur Transportanordnung führbar ist, daß die Transport- anordnung zwischen Entnahmeöffnung und Be- und Entladeein¬ richtung liegt und daß die Programmsteuerung der Be- und Ent¬ ladeeinrichtung und der Transportanordnung zugeordnet ist.The arrangement for carrying out the method is characterized in that the mounting table with removal opening is immediately adjacent to the warehouse, that the access element of the loading and unloading device can be guided to any parking space and to the transport arrangement, that the transport arrangement between removal opening and loading and Unloading device is located and that the program control of the loading and unloading device and the transport arrangement is assigned.
Eine derartige Anordnung bietet den Vorteil sehr kurzer Transportwege bzw. Bereitstellungszeiten. Die Zeit, die das Zugriffsorgan benötigt, um einen bestimmten Abstellplatz zu erreichen, kann weiter verkürzt werden, wenn das Lager bewegbar - insbesondere in horizontaler Richtung linear be¬ wegbar - ist. Somit kann es dem Zugriffsorgan beispielsweise auf halbem Fahrtweg entgegengefahren werden. Wird die Trans¬ portanordnung so ausgestaltet, daß sie außerhalb des Bereiches der zu bestückenden Leiterplatte lilegt, so kann die ergo- nomisch günstige Anordnung einer horizontalen Entnahmeöff¬ nung in unmittelbarer Nachbarschaft der zu bestückenden Lei- terplatte mit einem programmgesteuerten Schneide- und Biege¬ werkzeug kombiniert werden.Such an arrangement offers the advantage of very short transport routes or deployment times. The time that Access organ needed to reach a specific parking space, can be further shortened if the bearing is movable - especially linearly be¬ movable in the horizontal direction - is. Thus, it can be moved towards the access organ, for example, halfway. If the transport arrangement is designed in such a way that it lies outside the area of the printed circuit board to be assembled, the ergonomically favorable arrangement of a horizontal removal opening in the immediate vicinity of the printed circuit board to be assembled can be achieved with a program-controlled cutting and bending tool be combined.
Bei einer großen Anzahl benötigter Kleinteile-Behälter ist es sinnvoll, mehrere Teillager einzurichten. Dadurch werden überlange Fahrtwege vermieden. Um bei dieser Anordnung Wahl¬ freiheit beim Abtransport nicht mehr benötigter Behälter zu gewährleisten, ist jedem Teillager eine Be- und Entlädeein¬ richtung und mindestens eine Transportbahn zugeordnet. Dar¬ über hinaus ist es vorteilhaft, eine Verbindungseinrichtung zwischen den Lagern einzurichten, um das Auftreten einer Überbelegung eines einzelnen Teillagers zu verhindern und den Arbeitsablauf an der Entnahmeöffnung nicht zu stören. Vorzugsweise wird diese Verbindungseinrichtung mit einer antreibbareπ Fördereinrichtung ausgestattet.If a large number of small parts containers are required, it makes sense to set up several part stores. This avoids overly long journeys. In order to ensure freedom of choice with this arrangement when removing containers that are no longer required, a loading and unloading device and at least one transport track are assigned to each sub-storage facility. In addition, it is advantageous to set up a connecting device between the stores in order to prevent the occurrence of an overcrowding of an individual part store and not to disturb the work process at the removal opening. This connecting device is preferably equipped with a drivable conveyor device.
Jede Transportanordnung beinhaltet vorzugsweise eine Trans¬ porteinrichtung, die mindestens einer Transportbahn ent¬ spricht. Wird aber ein horizontal umlaufendes Förderband zur Verbindung von Bereitstellungsposition und Entnahmeöffnung gewählt, so kann dieses Förderband Kleinteile-Behälter sowohl zu- als auch abführen. Damit entspricht eine einzige Transporteinrichtung zwei Transportbahnen, wodurch die Transportanordnung mechanisch vereinfacht ist. Der Automa¬ tisierungsgrad der Anordnung zur Druchführung des erfin- dungsgemäßen Verfahrens läßt sich weiter erhöhen, wenn mittels Wägeeinrichtungen leere Kleinteile-Behälter erkannt werden; mittels der Programmsteuerung können dann bei Einsatz einer automatischen Beschickungsanlage die leeren Behälter durch volle ersetzt werden.Each transport arrangement preferably contains a transport device which corresponds to at least one transport track. However, if a horizontally circulating conveyor belt is chosen to connect the supply position and the removal opening, this conveyor belt can both feed and remove small parts containers. A single transport device thus corresponds to two transport tracks, as a result of which the transport arrangement is mechanically simplified. The degree of automation of the arrangement for carrying out the method according to the invention can be further increased if empty small parts containers are detected by means of weighing devices; Using the program control, the empty containers can then be replaced with full ones when using an automatic loading system.
Zur Erläuterung der Erfindung mit Hilfe von Ausführungsbei¬ spielen wird nachfolgend auf die figürlichen Darstellungen Bezug genommen. Es zeigen:To explain the invention with the help of exemplary embodiments, reference is made below to the figurative representations. Show it:
Figur 1 eine erste Anordnung zur Durchführung des erfin- dungsgemäßen Verfahrens in perspektivischer Darstellung, Figur 2 den Grundriß einer zweiten Anordnung zur Durchfüh¬ rung des erfindungsgemäßen Verfahrens und Figur 3 die Aufsicht der zweiten Anordnung.1 shows a perspective view of a first arrangement for carrying out the method according to the invention, FIG. 2 shows the outline of a second arrangement for carrying out the method according to the invention, and FIG. 3 shows the top view of the second arrangement.
Die in Figur 1 dargestellte Anordnung stellt einen Bestück¬ platz für Leiterplatten 1 dar. Deren Zufuhr erfolgt in Stapelbehältern 2 über eine Fördereinrichtung 3 und einen Stapellift 4. Eine Bedienpersoπ entnimmt die Leiterplatte 1 und legt sie in die Arbeitsposition des Bestücktisches 5. Die Bauteile befinden sich in Kleinteile-Behältern 6, die unterhalb des Arbeitsniveaus aus einem Lager 7 zu einer Ent¬ nahmeöffnung 8 des Bestücktisches 5 gebracht werden. Die Zufuhr der Kleinteile-Behälter 6 erfolgt über eine obere Transportbahn 9a und deren Abfuhr über eine untere Transport- bahn 9b. Der jeweils benötigte Kleinteile-Behälter 6 wird von einer Programmsteuerung festgelegt, die eine Be- und Entladeeinrichtung 10 zu dessen Position im Lager 7 steuert. Die Be- und Entladeeinrichtung 10 besteht aus zwei jeweils linear verfahrbaren Teilen, dem Horizontalteil 10a und dem Vertikalteil 10b. Dadurch ist jede Lageposition erreichbar. Der Vertikalteil 10b enthält zwei Zugriffsorgane, die den . beiden Transportbahnen 9a, 9b zugeordnet sind. Somit ent¬ nimmt nun das obere Zugriffsorgan den von der Programm¬ steuerung bestimmten Behälter 6 aus dem Lager. Anschließend wird von der Be- und Entladeeinrichtung 10 eine Bereitstel- lungsposition angefahren, an der der Kleinteile-Behälter 6 an die Transportbahn 9a übergeben wird. Gegebenenfalls über¬ nimmt das untere Zugriffsorgan einen Kleinteile-Behälter 6 von der unteren Transportbahn 9b, um ihn ins Lager 7 zurück- zubringen. Während die obere Transportbahn 9a den eben ge¬ brachten Kleinteile-Behälter 6 zur Entnahmeöffnung 8 bringt, holt die Be- und Entlageeinrichtung 10 den nächstfolgenden und bringt den nicht mehr benötigten an einen leeren Ab¬ stellplatz des Lagers 7. Dieser wird gleichfalls von der Programmsteuerung bestimmt und so gewählt, daß er möglichst nahe am nächsten benötigten Kleinteile-Behälter 6 liegt. Die, in den meisten Fällen neue, Position des abgestellten Behälters 6 wird gespeichert. Die durch die Arbeitsweise der Be- und Entladeeinrichtung 10 vorgegebene Bereitstellungszeit ist im Mittel kürzer als die von der Bedienperson des Be¬ stücktisches 5 benötigte Zeit für die Bestückung einer Lei¬ terplatte 1 mit den Bauteilen aus einem Behälter 6. Dadurch ist es möglich, mehrere Kleinteile-Behälter 6 auf der Trans¬ portbahn 9a aufzureihen. Somit wird die Bestückzeit der Be- dienperson nicht durch die Bereitstellungszeit für Kleinteile- Behälter 6 verlängert.The arrangement shown in Figure 1 represents a Bestück¬ place for printed circuit boards 1. They are fed into stacking containers 2 via a conveyor 3 and a stack lift 4. An operator removes the printed circuit board 1 and places it in the working position of the mounting table 5. The components are located located in small parts containers 6, which are taken below the working level from a warehouse 7 to a Ent¬ opening 8 of the placement table 5. The small-parts containers 6 are fed in via an upper transport track 9a and removed via a lower transport track 9b. The small parts container 6 required in each case is determined by a program control which controls a loading and unloading device 10 to its position in the warehouse 7 . The loading and unloading device 10 consists of two linearly movable parts, the horizontal part 10a and the vertical part 10b. This means that every position can be reached. The vertical part 10b contains two access organs, the. are assigned to both transport paths 9a, 9b. Thus, the upper access organ now removes the container 6 determined by the program control from the store. Subsequently, from the loading and unloading device 10 a provision ment position approached at which the small parts container 6 is transferred to the transport path 9a. If necessary, the lower access element takes over a small parts container 6 from the lower transport track 9b in order to bring it back to the store 7. While the upper transport track 9a brings the small parts container 6 that has just been brought to the removal opening 8, the loading and unloading device 10 fetches the next one and brings the one that is no longer required to an empty storage space in the warehouse 7. This is also controlled by the program control determined and chosen so that it is as close as possible to the next required small parts container 6. The position of the parked container 6, which is new in most cases, is saved. The delivery time specified by the operation of the loading and unloading device 10 is on average shorter than the time required by the operator of the loading table 5 for the loading of a printed circuit board 1 with the components from a container 6. This makes it possible to use several Line up small parts container 6 on the transport path 9a. Thus the loading time of the operator is not lengthened by the preparation time for the small parts container 6 .
Ein Monitor 11 informiert die Bedienperson über die Anzahl der zu entnehmenden Kleinteile. Dazu benötigt sie im Schnitt etwa drei Sekunden und kann anschließend mit Hilfe des Fu߬ schalters 12 für den Austausch des Kleinteile-Behälters 6 sorgen. Daraus ergibt sich eine mittlere Bereitstellungszeit für die Be- und Entladeeinrichtung 10 von weniger als drei Sekunden. Ein gleichfalls von der Programmsteuerung geführ- ter Leuchtzeiger 13 bezeichnet der Bedienperson die Position der Kleinteile auf der zu bestückenden Leiterplatte 1. Unter der Leiterplatte 1 befindet sich ein nicht dargestelltes Schneide- und Biegewerkzeug. Dieses kürzt die Anschlußdrähte der Kleinteile und biegt sie, damit sie während des Weiter- transportes der Leiterplatte 1 zu einem Lötbad nicht aus der Leiterplatte 1 fallen können. Da die Leiterplatten 1 unter¬ schiedliche Größen aufweisen, sind in einem Regal 14 Masken¬ einsätze zur Anpassung aufbewahrt.A monitor 11 informs the operator of the number of small parts to be removed. To do this, it takes about three seconds on average and can then use the foot switch 12 to replace the small parts container 6 . This results in an average availability time for the loading and unloading device 10 of less than three seconds. A luminous pointer 13, which is also guided by the program control, indicates to the operator the position of the small parts on the printed circuit board 1 to be fitted. Below the printed circuit board 1 there is a cutting and bending tool (not shown). This shortens the connecting wires of the small parts and bends them so that they do not come out of the solder bath during the onward transport of the printed circuit board 1 PCB 1 can fall. Since the printed circuit boards 1 have different sizes, 14 mask inserts are stored on a shelf for adaptation.
Leere Kleinteile-Behälter 6 können durch eine Wägeeinrich¬ tung beispielsweise im Vertikalteil 10b erkannt werden. Die Programmsteuerung regelt dann den Austausch leerer Behälter 6 gegen volle mit Hilfe einer externen Beschickungsanlage. Dieser Austausch erfolgt über die dem Bestücktisch 5 abge- wandte Seite des Lagers 7. Es sind aber auch einfachere Lösungen dieses Problems denkbar. Ist beispielsweise die ursprüngliche Anzahl der Kleinteile in einem Behälter 6 in der Programmsteuerung gespeichert, so kann diese durch Subtrahieren der Zahl der entnommenen Kleinteile den Zeit- punkt zum Auffüllen des entsprechenden Behälters 6 veran¬ lassen.Empty small parts containers 6 can be detected by a weighing device, for example in the vertical part 10b. The program control then regulates the exchange of empty containers 6 for full ones with the aid of an external loading system. This exchange takes place via the side of the bearing 7 facing away from the mounting table 5. However, simpler solutions to this problem are also conceivable. If, for example, the original number of small parts in a container 6 is stored in the program control, then by subtracting the number of small parts removed, the program control can determine the time for filling the corresponding container 6 .
Es können auch zwei Bestücktische an derselben Seite eines gemeinsamen Lagers angeordnet sein. Bei entsprechend schnellen Verfahrbeweguπgen der Be- und Entladeeinrichtung 10 kann diese zur Versorgung beider - vorzugsweise einander gegenüberstehend angeordneten - Bestücktische eingesetzt werden.Two assembly tables can also be arranged on the same side of a shared warehouse. With correspondingly rapid movements of the loading and unloading device 10, it can be used to supply both placement tables—preferably arranged opposite one another.
Das in den Figuren 2 und 3 dargestellte zweite Ausführungs¬ beispiel unterscheidet sich vom ersten im wesentlichen durch ein zweigeteiltes Lager 7a, 7b und eine Transportanordnung, die durch flexible Arbeitsweise die Bereitstelluπgszeiten der einzelnen Kleiπteile-Behälter 6 weiter verkürzt. Jedem der beiden Teillager 7a, 7b ist eine eigene Be- und Entlade¬ einrichtung 10 - nur für das Teillager 7a dargestellt - mit jeweils einem Zugriffsorgaπ zugeordnet. Die Transportaπord- nung besteht aus zwei Transportbahnen 9, die von zwei ein¬ ander gegenüberliegenden Seiten zur Entnahmeöffnuπg 8 füh- ren. Das Besondere an dieser Anordnung ist, daß nunmehr jede der beiden Transportbahnen 9 Kleinteile-Behälter 6 zu- oder auch abführen kann, entweder voneinander unabhängig oder im Zusammenspiel. Die Programmsteuerung bestimmt, jenachdem, ob Kleinteile-Behälter 6 aus dem rechten 7b oder linken Teil- lager 7a geholt werden müssen, die Transportrichtung. Wenn ein Kleinteile-Behälter 6 beispielsweise von links unter die Entnahmeöffnung 8 gebracht wird, ist es vorteilhaft, ihn nach rechts abzutransportieren, wenn der nächste gleichfalls von links kommt. Falls der nächste aber bereits rechts be- reitsteht, muß der Kleinteile-Behälter 6 wiederum nach links auf einen leeren Abstellplatz gebracht werden. Um diese Ar¬ beitsweise bei einem nur geringen Überangebot an leeren Abstellplätzen aufrechterhalten zu können, benötigt man eine zusätzliche Verbindungseinrichtung 15. Diese sorgt für Aus- gleich, indem sie ermöglicht, Kleinteile-Behälter 6 von einem Teillager 7a oder 7b direkt zu dem anderen zu transpor¬ tieren.The second exemplary embodiment shown in FIGS. 2 and 3 differs from the first essentially by a two-part store 7a, 7b and a transport arrangement which further shortens the availability times of the individual small parts containers 6 due to flexible operation. Each of the two sub-warehouses 7a, 7b has its own loading and unloading device 10--shown only for sub-warehouse 7a--assigned to one access organ each. The transport arrangement consists of two transport paths 9, which lead to the removal opening 8 from two opposite sides. The special feature of this arrangement is that now each of the two transport paths 9 small parts container 6 can supply or discharge, either independently or in combination. The program control determines the direction of transport depending on whether small parts containers 6 have to be fetched from the right part store 7b or the left part store 7a. If a small parts container 6 is brought under the removal opening 8 from the left, for example, it is advantageous to transport it away to the right if the next one also comes from the left. However, if the next one is already on the right, the small parts container 6 must be moved to an empty parking space on the left. In order to be able to maintain this working method with only a slight oversupply of empty parking spaces, an additional connecting device 15 is required. This ensures compensation by enabling small parts containers 6 to be moved from one sub-storage facility 7a or 7b directly to the other transport animals.
Auch bei diesem zweiten Ausführungsbeispiel der Erfindung sind die Kleinteile-Behälter 6 in jeden beliebigen, leerem Abstellplatz zurückbringbar, ihre Position wird ebenfalls von der Programmsteuerung gespeichert. In einer Kombination beider Ausführungsbeispiele ist die Entnahmeöffnung 8 doppelt so lang und mit einem Schiebedeckel versehen. Von zwei Seiten werden die Kleinteile-Behälter 6 aus zwei Teil¬ lagern 7a, 7b über je zwei Transportbahnen 9a, 9b sowohl zu-, als auch abgeführt. Der jeweils benötigte Teil der Entnahme¬ öffnung 8 wird vom Schiebedeckel freigegeben.In this second exemplary embodiment of the invention, too, the small-parts containers 6 can be returned to any empty parking space, and their position is also stored by the program control. In a combination of both exemplary embodiments, the removal opening 8 is twice as long and is provided with a sliding cover. From two sides, the small-parts containers 6 are supplied from two part stores 7a, 7b via two transport tracks 9a, 9b each, as well as removed. The part of the removal opening 8 required in each case is released by the sliding cover.
Zum Aufbau der Be- und Entladeeinrichtung 10, der Transport¬ anordnung und des Verbinders 15 sind in den Ausführungsbei¬ spielen Einrichtungen verwendbar, wie sie im Prospekt "Modu¬ lares Handhabungssystem" der Firma Siemens, MCH 01810.8310., gezeigt sind. Die Be- und Entladeeinrichtungen 10 können beispielsweise aus sogenannten "Portalladern" bestehen, wie sie Seite 3 zeigt. Die Transportbahnen 9, 9a, 9b der Trans¬ portanordnung und die Verbiπdungseinrichtung 15 können "Portalachsen" gemäß Seite 6 sein. Es ist auch keineswegs zwingend, das Lager 7, 7a, 7b linear anzuordnen. Bei Ver- wendung eines dreh- und schwenkbaren Armes als Be- und Ent¬ ladeeinrichtung 10 kann auch eine Aufstellung entlang eines Teils eines Kreisbogens gewählt werden.To set up the loading and unloading device 10, the transport arrangement and the connector 15, devices can be used in the exemplary embodiments, as shown in the prospectus "Modular Handling System" from Siemens, MCH 01810.8310. The loading and unloading devices 10 can consist, for example, of so-called “gantry loaders”, such as she shows on page 3. The transport tracks 9, 9a, 9b of the transport arrangement and the connecting device 15 can be "portal axes" according to page 6. It is also by no means mandatory to arrange the bearing 7, 7a, 7b in a linear manner. When using a rotatable and pivotable arm as the loading and unloading device 10, it is also possible to set it up along part of an arc of a circle.
Bestücktische gemäß der Erfindung eignen sich besonders zur Bestückung kleiner Serien von Leiterplatten sowie zur Repa¬ ratur und Nachbestückung von automatisch verarbeiteten Lei¬ terplatten. Assembly tables according to the invention are particularly suitable for assembling small series of printed circuit boards and for repairing and replenishing automatically processed printed circuit boards.
