Description

Technical area

The present invention relates to devices and methods for punching out packaging produced in at least one film. The invention also relates to packaging machines which include the devices mentioned.

State of the art

Packaging machines are out of the EP 1 598 276 B1 , EP 2 447 171 B1 as well as from the DE 20 2008 013 659 U1 known. These packaging machines are film packaging machines in which packaging troughs are formed in a first film, the so-called lower film, with the aid of a deep-drawing process. The troughs are then filled with a content such as food. After filling the wells, they are covered with a second film, the so-called upper film, and then welded to the lower film. The packages produced and sealed in this way are then cut out of the films with the aid of a cutting tool.

From the DE 20 2008 013 659 U1 a packaging machine is known which comprises at least one cutting knife for cutting the packaging produced in the films. The at least one cutting knife has a cutting edge. The cutting edge has at least one interruption. During the cutting process, a retaining web or a connection to the film web (the film scrap lattice) remains at the point of the at least one interruption. The packaging thus remains connected to the residual film grid via the retaining webs / connections and a subsequent breaking-out process is necessary in order to finally separate the cut-out packaging from the film. One advantage of this technology is that the cut-out packaging can be transported out of the cutting station or the cutting tool in a simple manner together with the scrap skeleton. However, considerable problems can arise if the contents of the packaging are heavy and the thin retaining webs are excessively stressed. This is because there is then the risk that retaining webs cannot hold the weight of the contents and tear in the cutting tool or during transport to the stripping station. The packaging machine then has to be stopped, which interrupts the production cycle. In addition, there is a risk that retaining webs in the stripping station will not be cut through evenly and cleanly, as a result of which the appearance of the packaging will suffer.

It is therefore the object of the present invention to provide a device for punching or cutting out packaging produced in at least one film, which can be integrated into conventional packaging machines, is simple and inexpensive and overcomes the above-mentioned disadvantages of the prior art.

Brief outline of the invention

To achieve at least the above-mentioned objects, according to one aspect, a device for punching out packaging produced in at least one film is provided, the device comprising: a punching tool comprising a punching die and a counter-punching plate, the punching die having at least one cutting line which has the contour of the simulates at least one packaging, so that the at least one packaging is punched out of the at least one film in one punching stroke; and a holding device which is provided for temporarily holding the at least one punched-out packaging after the punching-out process and then transferring it to a transfer device or a packaging receiving device.

In the description, the terms “punching out” and “cutting out” are used synonymously.

According to the present invention, the punching tool is designed in such a way that it completely punches out (or cuts out) the at least one packaging. This means that the at least one packaging does not have any retaining webs or connections to the residual film lattice after the punching process. The completely punched out at least one packaging is temporarily (i.e. temporarily) held by the holding device so that the at least one packaging does not remain in the punching tool. The holding device is also designed to hold the at least one punched-out packaging until a transfer device is positioned in the punching tool to take over the at least one punched-out packaging, or the packaging can be fed to a packaging receiving device.

The punching form of the punching tool can have at least one cutting line. Furthermore, the punching die can comprise a carrier plate for receiving the at least one cutting line. The at least one cutting line can be designed as at least one steel strip line. The at least one cutting line can be arranged on the carrier plate in such a way that it reproduces the contour of the at least one packaging to be punched out. Furthermore, the die (and the counter die plate) be designed in such a way that they can simultaneously punch several packagings from the film with one punching stroke.

The counter-punching plate can have recesses or openings into which the shaped (for example deep-drawn) packaging can protrude during the punching process.

The punching mold and / or the counter-punching plate of the punching tool that interacts with the punching mold can be movably mounted in the device. According to a variant, the punching die with the at least one cutting line can be arranged above the counter punching plate. According to another variant, the counter punching plate can be arranged above the punching die with the at least one cutting line. Regardless of the specific spatial arrangement of the punching die and the counter-punching plate, the punching form and / or the counter-punching plate can be movably mounted in the device in such a way that the punching form and the counter-punching plate can be moved towards one another during a punching process in order to create at least one film arranged between the punching form and the counter-punching plate to be punched (or cut out) with packaging. This process is called closing the punching tool. After completion of the punching process, the punching die and the counter punching plate can be moved apart again in order to be able to remove the at least one punched-out packaging from the punching tool. This process is called opening the punching tool.

The holding device can be arranged in the punching tool. According to a variant, the holding device can be arranged in the punching die. The holding device can be arranged within the at least one cutting line of the punching die. According to an alternative variant, the holding device can be arranged on the counter punching plate. The arrangement of the holding device on the punching die or the counter-punching plate can cause the completely punched-out packaging (s) to be carried along with the holding device when the punching tool is opened. If the holding device is arranged on the die, the at least one packaging is carried along with the die when the die is opened. If the holding device is arranged on the counter-punching plate, the at least one punched-out packaging is carried along with the counter-punching plate when the punching tool is opened.

The holding device can be designed in the form of a vacuum device. The vacuum device can be actuatable (can be activated and deactivated). By activating the vacuum device, a vacuum can be built up by which the punched-out packaging (s) is / are held on the holding device. By deactivating the holding device, the negative pressure can be reduced again, as a result of which the packaging (s) held on the holding device detach / detach from the holding device.

The device can furthermore comprise a transfer device. The transfer device can be designed to take over the at least one punched-out packaging from the holding device and to convey it out of the punching tool. For this purpose, the transfer device can be movably mounted in the device and can be moved back and forth between a first position located inside the punching tool and a second position located outside the punching tool. In the first position, the transfer device can be located between the punching die and the counter-punching plate in order to take over the punched-out packaging (s) from the holding device. The transfer device can only move to the first position when the punching tool is open. In the second position, the transfer device can be located outside the tool in order to transfer the punched-out packaging (s) to a further conveying unit or a packaging receiving unit. The transfer unit can remain in the second position while the punching tool is closed.

Instead of the above-described transfer unit, which removes the packaging (s) from the punching tool after each punching cycle, the device can comprise a packaging receiving device which is arranged below the punching tool (the lower tool component). The lower tool component can be movably mounted here. It can be moved back and forth between a punching position and a release position. In the punching position, the lower tool component interacts with the upper tool component in order to punch the at least one packaging. In the release position, the packaging receiving device located below becomes accessible to the holding device arranged on the upper tool component, so that the holding device can drop the at least one package into the packaging receiving device located below. According to one implementation, the lower tool component can be the counter punching plate. Correspondingly, the upper tool component is the punching die on which the holding device is arranged. According to an alternative implementation, the lower tool component can be the die. Correspondingly, the upper tool component is the counter punching plate on which the holding device is arranged.

According to a further aspect, a device for punching out packaging produced in at least one film is provided. The device comprises a punching tool with a punching mold and a counter-punching plate cooperating with the punching form, the punching mold being arranged below the counter-punching plate and having at least two sections which are each provided for punching out and for temporarily receiving the at least one packaging. The cutting die is movably mounted in the device (for example horizontally displaceable or horizontally pivotable) and can be moved back and forth between two positions in such a way that: (a) in a first position the first cutting die section comes into contact with the at least one film and the counter-cutting plate, to punch at least one packaging from the film and receive it, and (b) in a second position the second die section comes into contact with the at least one film and the counter-punching plate in order to punch at least one further packaging from the film and receive it, and at the same time the first die section is moved away from the at least one film and the counter-die plate, so that the packaging received in the first die section can be removed.

With each new punching cycle, the punching form changes its position, so that it is possible to punch alternately with the first punching form section and with the second cutting form section. By dividing the die into the first die section and the second die section as described, it is possible to punch at least one package from the film with each die cutting cycle and at the same time remove packaging from a previous die cycle from the die.

According to a further aspect, a device for punching out packaging produced in at least one film is provided. The device comprises a punching tool with a punching die and a counter-punching plate that interacts with the punching die during the punching process. The counter-punching plate is arranged below the punching die and has at least one recess or an opening which is provided for temporarily receiving the at least one packaging. The counter-punching plate is also movably mounted and can be moved back and forth between two positions in such a way that: (a) in a first position the counter-punching plate comes into contact with the at least one film and the cutting die in order to punch at least one package from the film and receive it , and (b) in a second position the counter-punching plate is moved away from the cutting die, so that the packaging received in the counter-punching plate can be removed.

Detailed description

In connection with the 1 is now a method according to the invention 100 for punching out packaging produced in at least one film (eg lower film and upper film). The process can be carried out with a punching device, as will be described in more detail in the following figures.

In a first step S110 a punching tool with a punching die and a counter punching plate and a holding device arranged in the punching tool are provided.

In a subsequent second step S120 the at least one film is positioned between the punching die and the counter-punching plate. The at least one film can comprise a lower film and an upper film, the lower film containing the at least one shaped packaging (ie one or more packaging) and the upper film being provided for covering and sealing the shaped packaging (s).

In a further step S130 the punching tool is closed, ie the punching die and the counter-punching plate are moved towards each other and come into contact, so that the punching form presses the at least one film against the counter-punching plate and punches (or cuts out) the at least one packaging from the at least one film.

In a further step S140 the holding device is activated (actuated) in order to hold the at least one punched-out packaging.

In a further step S150 the punching tool is opened, the at least one punched-out packaging being held in the punching tool with the aid of the holding device when the punching tool is opened.

In a further step S160 the holding device is deactivated in order to transfer the at least one packaging into a packaging receiving device or a transfer device that can be positioned in the punching tool.

With the method according to the invention 100 the at least one packaging can thus be completely punched out of the at least one film. No holding bars or connections to the scrap foil are necessary. At the same time, the at least one punched-out packaging is temporarily (that is, for a limited time) held with the holding device and is fed to a transfer device or a packaging receiving device with the punching tool open. A new punching cycle can then begin, with the method steps described above being repeated.

In connection with the 2a and 2 B becomes a punching device 1 for a packaging machine for the execution of the in connection with the 1 described procedure 100 further described. The device 1 is for punching out at least one film 1000 produced packaging 1200 intended. With at least one packaging 1200 It can be food packaging which consists of a lower film and an upper film, with packaging trays for receiving food being formed in the lower film, and the upper film being provided for closing the packaging trays.

The punching device 1 includes a punching tool 10 comprising a die 12th and a counter punching plate 18th . The die 12th includes a support plate 13th with at least one cutting line 14th . The at least one cutting line 14th is like this on the carrier plate 13th arranged that it follows the contour of the at least one packaging to be punched out 1200 replicates. The counter punching plate 18th can have at least one recess or at least one opening (in the 2a and 2 B not shown), in which the at least one package during the punching process 1200 can protrude.

As also from the 2a As can be seen, includes the punching device 1 a holding device 16 . The holding device 16 is on the die 12th arranged. You can within the at least one cutting line 14th be arranged. The holding device 16 can be designed as a vacuum device (or suction device). It can be controlled by a control device (in the 2a and 2 B not shown) can be optionally activated and deactivated. By activating the holding device 16 there is a negative pressure (or suction force) on the cutting die 12th generated, whereby the die-cut packaging 1200 on the holding device 16 (and thus on the die 12th ) is temporarily held (see 2 B) . By deactivating the holding device 16 the generated negative pressure (or the suction force) is reduced again, which causes the packaging 1200 from the holding device 16 releases and to an underlying transfer device 20th is passed.

The device 1 further comprises the transfer device 20th . The transfer facility 20th is provided for the at least one punched-out packaging 1200 from the punching tool 10 to transport. This is what the transfer device is for 20th movable in the device 1 stored (see Storage 22nd in 2a and arrow 24 , which the directions of movement of the transfer device 20th indicates. The transfer facility 20th is movably mounted in such a way that it is between a first position in which the transfer device 20th inside the punching tool 10 is positioned (see 2 B -> solid representation of the transfer device 20th ), and a second position in which the transfer device 20th outside the punching tool 10 is positioned ( please refer 2 B -> dashed representation of the transfer device 20th ), can be moved back and forth. In the embodiment shown is the transfer device 20th designed as a (horizontally) movable table.

In connection with the 2a and 2 B becomes the operation of the punching device 1 further described within a punching cycle.

The punch cycle begins when the punch tool closes 10 after the at least one slide 1000 with the at least one packaging to be punched out 1200 between the die 12th and the counter punching plate 18th was ordered (see 2a) . The transfer facility 20th is in its second position outside the punching tool 10 . By closing the punching tool 10 will be the at least one slide 1200 pressed against the counter punching plate and along the at least one cutting line 14th (completely) severed. What remains is a cohesive scrap film 1100 coming out of the punching tool 10 is led out and on a spool 1400 is wound up. In the 2a is to the left of the punch 10 the foil 1000 with the packaging still to be punched out 1200 shown. To the right of the punching tool 10 is the foil scrap lattice 1100 indicated, wherein the holes generated by the punching process in the film scrap lattice 1100 are not shown.

In 2 B becomes the punching tool 10 opened after the punching process. That means the die 12th and the counter punching plate 18th be moved apart. The opening and closing of the punching tool 10 can be realized by either cutting the die 12th or the counter punching plate 18th or both components of the punching tool 10 (vertically) movable in the device 1 are stored. As in 2 B can be seen by activating the holding device 16 the at least one die-cut packaging 1200 on the die 12th held. The holding device 16 prevents the at least one completely punched-out packaging 1200 when opening the tool 10 in the tool 10 remains lying uncontrollably. After opening the punching tool 10 becomes the transfer facility 20th between the counter punching plate 18th and the die 12th positioned. The one above the transfer device 10 lying and from the holding device 16 held at least one package 1200 , can now be sent to the transfer device 20th be handed over. This is done by deactivating the holding device 16 . The transfer device can then 20th in their second, outside the punching tool 10 horizontal position (dashed representation in the 2 B) and thus the punched-out packaging 1200 from the punching tool 10 removed.

The foil 1000 can now be retraced (i.e. in the representations of the 2a / 2b can be moved to the right), so that at least one new packaging to be punched out 1200 in the tool 10 is positioned. The punching cycle described above can then be repeated.

In connection with the 3a and 3b is now another punching device 1a for a packaging machine that is used to carry out the in the 1 described procedure is provided. The punching device 1a differs from that in the 2a and 2 B punching device described 1 essentially that in the punching tool 10a the counter punching plate 18th over the die 12th is arranged. Furthermore, the holding device 16 on the counter punching plate 18th arranged. The holding device 16 is again implemented in the form of a vacuum device (or suction device). It is designed to work on the die 12th facing surface of the counter punching plate 18th to generate a holding force (suction force) around the at least one completely punched-out packaging 1200 on the counter punching plate 18th to keep. How Stanzform works 12th , Counter punching plate 18th , Holding device 16 and transfer device 20th corresponds to the functionality of the corresponding components in connection with the 2a and 2 B punching device described 1 .

The punching out of the at least one package 1200 from the slide 1000 and removing the at least one punched-out packaging 1200 from the punching tool 10a takes place analogously to the device 1 in the 2a and 2 B . In other words, the punching tool is used first 10a closed to the at least one packaging 1200 from the at least one film 1000 (completely) punched out. The transfer facility 20th is located in your outside of the punching tool during the punching process 10a lying second position. The punching tool is then used 10a opened by moving apart, whereby when opening the punching tool 10a the at least one die-cut packaging 1200 with the help of the holding device 16 on the counter punching plate 18th is recorded (see 3b) . The transfer device can then 20th between the counter punching plate 18th and the underlying die 12th be positioned (first position of the transfer device 20th ). By deactivating the holding device 16 can the packaging 1200 away from the counter punching plate 18th loosen and on the transfer device 20th be filed. The transfer device can then 20th from the punching tool 10 moved to their second position (dashed line in the 3b) .

In connection with the 4a and 4b becomes another punching device 1b for a packaging machine that is used to carry out the in the 1 described procedure is provided. The punching device 1b includes a punching tool 10b . The punching tool 10b includes a die 12th with at least one cutting line 14th , as in connection with 1a described. It is also in the stamping form 12th a holding device 16 arranged, which is designed and functions in the same way as in connection with the 2a and 2 B described. Reference is made to the corresponding description above.

The main difference between the punching device 1b and those in the 2a and 2 B is that the counter punching plate 18th is horizontally moveable (see Storage 18a ) and below the counter punching plate 18th a package receiving device 19th is provided. The counter punching plate 18th can choose between a first position, the so-called punching position (see 4a) , and a second position, the so-called release position (see 4b) to be moved back and forth. The counter-punching plate is in place during the punching process 18th in the punching position (see 4a) . It works with the die above 12th together in such a way that they are in the punching tool 10b located at least one packaging 1200 (completely) punched out. When open (see 4b) becomes the counter punching plate 18th move into the release position, whereby the underlying packaging receiving device 19th is released. The by the holding device 16 on the die 12th held at least one package 1200 can now by deactivating the holding device 16 be dropped (see 4b -> dashed representation). The packaging 1200 falls directly into the packaging receiving device below 19th . Then the counter punching plate 18th can be moved back to the punching position and a new punching cycle can begin.

In connection with the 5 is now a further method according to the invention 500 for punching out in at least one film 1000 (e.g. lower film and upper film) produced packaging 1200 described. The procedure 500 can for example with a punching device 1c as in the 6a and 6b are shown. The procedure 500 and the device 1c are discussed together below.

In a first step S510 becomes a punching tool 10c with a die 12c and a counter punching plate 18c provided. The counter punching plate 18c is below the die 12c arranged and has at least one recess or an opening 17c on which for (temporarily) receiving the at least one packaging 1200 is provided. Furthermore, the counter punching plate is in the punching device 1c designed to be moveable (see bearing elements 15c and 15d in the 6a) .

The die 12c has a support plate 13th with cutting lines 14th on. The cutting lines 14th and carrier plate 13th can be designed in the same way as in connection with the punching device 1 in the 2a and 2 B described. In particular are the cutting lines 14th on the carrier plate 13th arranged in such a way that it follows the contour of the at least one packaging to be punched out 1200 replicate (see 6a) .

In a subsequent second step S520 will be the at least one slide 1000 with at least one packaging 1200 between the die 12c and the counter punching plate 18c positioned (see 6a) . The at least one slide 1000 may comprise a lower film and an upper film, the lower film comprising the at least one shaped packaging 1200 and the top film is provided for covering and sealing the molded packaging (s).

In a further step S530 becomes the punching tool 10c closed so that the cutting die 12c with the at least one foil 1000 and the counter punching plate 18c comes into contact with the at least one packaging 1200 from the at least one film 1000 to punch. (please refer 6b -> packaging shown in dashed lines).

In a further step S540 becomes the punching tool 10c reopened (ie the counter punching plate 18c and the die 12c are moved apart in the vertical direction), so that the in the at least one breakthrough 17c the counter punching plate 18c recorded packaging 1200 can be taken.

According to one implementation of the step S540 becomes the counter punching plate 18c after opening the punching tool 10c tilted downwards. The tilting movement is in the at least one breakthrough 17c the counter punching plate 18c recorded at least one packaging 1200 from the counter punching plate 18c ejected. It can fall into an underlying packaging receiving device.

In the in the 6a and 6b punching device shown 1c the tilting movement is caused by the bearing elements 15c and 15d realized. The counter punching plate 18c is at one end of the plate (left end in the 6a and 6b) around an axis of rotation 15c pivoted. The counter punching plate is located at its opposite end 18c at a displaceable bearing element 15d on. By moving the bearing element 15d outwards (to the right in the 6a) becomes the support of the counter punching plate 18c on the bearing element 15d withdrawn. Due to the force of gravity, the counter punching plate tilts 18c downward. The tilting mechanism described is only an example. Other implementations of the tilting mechanism are conceivable, such as, for example, a hydraulically, pneumatically or an electromechanically controlled tilting mechanism.

To support the ejection process of the at least one package 1200 the punching device can have at least one ejector device (hereinafter referred to as ejector element 11c called) include. The at least one ejection element 11c is arranged in such a way that there is at least one opening during the tilting process 17c penetrates and thus in the at least one breakthrough 17c ejects picked up packaging (s).

In connection with the 7th is now a further method according to the invention 700 for punching out in at least one film 1000 (e.g. lower film and upper film) produced packaging 1200 described. The procedure 700 can for example with a punching device 1d as in the 8a to 8c are shown. The procedure 700 and the device 1d are discussed together below.

In a first step S710 becomes a punching tool 10d with a die 12d and a counter punching plate 18d provided, the die 12d below the counter punching plate 18d is arranged and at least two sections 12e and 12f has (see 8c ). Each of the sections 12e and 12f has at least one cutting line 14th on which the contour of the at least one packaging to be punched out 1200 replicates. The cutting lines 14th both sections are on the carrier plate 13th the die 12d arranged.

In a subsequent second step S720 will be the at least one slide 1000 (with at least one packaging 1200 ) between the die 12d and the counter punching plate 18d positioned. The at least one slide 1000 can comprise a lower film and an upper film, the lower film containing the at least one shaped packaging and the upper film for covering and sealing the shaped packaging (s) 1200 is provided.

In a further step S730 becomes the die 12d moved to a first punching position and then the punching tool 10d closed so that the cutting die 12d with their first die section 12e with the at least one foil 1000 and the counter punching plate 18d comes into contact with the at least one packaging 1200 from the slide 1000 to punch. The at least one die-cut packaging 1200 remains in the die 12d . To ensure that the at least one package stays safe 1200 in the die 10d to enable the die cutting die 10d with a holding device 16 be equipped. The holding device can be designed as a vacuum device, which is in the punching die 10d is integrated and optionally a negative pressure (suction force) on the at least one package 1200 exercises in order to hold them in place temporarily.

In a subsequent step S740 becomes the punching tool 10d open (see 8b) , when opening the punching tool 10d the at least one die-cut packaging 1200 in the first die section 12e the die 12th remains (or by means of a holding device 16 is held).

In a further step S750 becomes the die 12d moved to a second punching position and then closed again so that the punching die 12d with their second die section 12f with the at least one foil 1000 and the counter punching plate 18d comes in contact to at least one more packaging 1200 from the at least one film 1000 to punch and record. This second punching with the second punching die section 12f is in the 8c shown, which is a schematic plan view of the device 1d shows. As from the 8c it shows the movement of the die 12d between successive punching cycles horizontally and transversely to the course of the at least one film 1000 .

In a further step S760 becomes the one in the first die section 12e recorded at least one package removed while the cutting die 12d with their second die section 12f the foil punches. In other words, the steps can S750 and S760 run at the same time. This configuration is in the 8c shown in which the second die section 12f below the at least one film 1000 lies to packaging 1200 punch out during the first die section 12e outside of the at least one slide 1000 and thus for the removal of the previously punched out packaging 1200 becomes accessible.

The advantage of this implementation is that an external holding device and transfer device can be dispensed with. By moving the die back and forth 12d relative to the at least one film 1000 (and the counter punching plate 18d) can pack with each new punching stroke 1200 be punched out and at the same time the packaging punched out with the previous punching stroke 1200 can be removed.

In connection with the 9 now becomes a packaging machine 2000 described which one of the punching devices described above 1 , 1a , 1b , 1c , 1d includes.

The packaging machine 2000 includes a forming station 3 , a filling station 5 , a sealing station 7th and one of the punching devices described above 1 , 1a , 1b , 1c , 1d . The packaging machine also includes 2000 an unwinding device 1300 , which is intended to store and unroll a roll of film and the forming station 3 to feed. On the opposite side includes the packaging machine 2000 a winder 1400 . The take-up device 1400 is intended to do this after punching out the packaging 1200 generated foil scrap lattice 1100 to wind up.

The following is how the packaging machine works 2000 further described. With each punching cycle, the film is removed from the unwinding device 1300 first of all the forming station 3 fed. The forming station 3 is designed to have packaging hollows in the film 1000 to shape. This can be done, for example, by a deep-drawing process. The one in the slide 1000 The packaging produced is then sent to the filling station 5 fed. The filling station 5 fills the shaped packaging trays with a content to be packaged (e.g. food). Then the slide 1000 with the packaging 1200 the sealing station 7th fed. In the sealing station 7th are the open-topped packaging 1200 with the help of another slide 1000 (the so-called upper film) covered and sealed. Following are the slides 1000 (Lower film and upper film) together with the packaging 1200 moved on to the punching station / punching device. In the punching device 1 , 1a , 1b , 1c , 1d will be the packaging 1200 from the slides 1000 completely punched out, as in connection with the 1 to 8c described above. The remaining foil scrap lattice 1100 is on the output side of the winder 1400 fed, which winds up the foil scrap lattice.

The devices and methods described here have the advantage that packaging punched out of a film can be safely and quickly removed from the punching tool. The technology according to the invention makes it possible to dispense with the implementation of retaining webs or connections between the packaging and the scrap skeleton.
