Definitions

  • the invention relates to a slicing machine with a depositing device for depositing sliced food, e.g. Sausage, in a depositing position, in which a welding station of a packaging device is provided, which comprises a base plate with an electrically heatable welding wire or strip and a removable Anpressteil for pressing and marginal welding of at least two plastic material enveloping the clippings.
  • a welding station of a packaging device which comprises a base plate with an electrically heatable welding wire or strip and a removable Anpressteil for pressing and marginal welding of at least two plastic material enveloping the clippings.
  • From the EP 849177 A is a slicing machine with packaging known, in which a cold cut fully automatically placed on a film and this is covered with another film. From the depositing position, the cold cuts arrive at a welding station in which the foils are pressed by means of a lifting frame against a welding frame for edge-side welding. In a further development, the welding station was moved to the storage position. The tray has around the rectangular support sheet for the cold cuts around four superscript and folding against the carrier film bars. If the cold cuts are deposited on the carrier foil, then a cover foil is placed over it. The strips fold to the center and press the edge of the two films down against a heating wire, which performs the edge welding of the two enveloping the slices of film.
  • the invention aims to provide the packaging directly on the To produce slicing machine and to evacuate.
  • the pressing part is designed as a suction cup with a Anpressrand, which is in connection with a vacuum device that the suction cup in guides horizontally from a retracted waiting position during the slicing and depositing process, preferably under a chain frame of the depositor through the depositing position is movable and that for evacuating and pressing the plastic films on the base plate approximately parallel to the rotating welding wire or -band an elastically compressible frame made of airtight material, eg made of sponge rubber, the Anpressrand is opposite and while moving and placing the suction cup a space bounded laterally as a vacuum chamber.
  • a vacuum device that the suction cup in guides horizontally from a retracted waiting position during the slicing and depositing process, preferably under a chain frame of the depositor through the depositing position is movable and that for evacuating and pressing the plastic films on the base plate approximately parallel to the rotating welding wire or -band an elastically compressible frame made of airtight material, eg made of sponge
  • the suction cup for example, includes a rectangular frame as Anpressrand, which surrounds a cup-shaped depression plate edge similar, is initially outside the storage position, so as not to hinder the depositing process. Only after completion of the cold cuts, the suction cup is positioned above the cold cuts. The cold cuts lie on the plastic film as a carrier film and is covered by a second plastic film loosely. As soon as the suction cup lowers against this arrangement and the edge of the suction cup rests on the compressible frame, the evacuation begins. The negative pressure pulls the suction cup against the base plate, and in the end position, the pressing edge presses the two foils against the heating wire for welding. The negative pressure also causes an evacuation of the area between the plastic films. The vacuum remains after welding, since the welding takes place without gaps.
  • the slicing machine has a chain frame for conveying the sliced slices away from the circular blade in the direction of the depositing tray.
  • a racket engages behind the chains of the chain frame and throws the discs in the depositing position.
  • An object of the invention is the slicing machine as Counter unit as compact as possible, even with an integrated evacuating packaging device.
  • it is expedient for the movement of the movable in and out of the Ablegeposition suction cup when their guides reduce the vertical distance of Anpress presses the base plate to the touchdown of the Anpressrandes on the compressible frame in the depositing position and the suction cup in this position in the vertical direction the lowering is released when sucking.
  • the suction cup formed with a substantially rectangular outer contour can run as a slide in both sides lateral linear guides, which are angled over the depositing position in the direction of this. So it is the suction cup moved back and forth, at the end of the forward movement, the lowering and placing the suction cup on this frame, here, for example, on a sponge rubber. As mentioned, this forms the vacuum chamber in which evacuates the suction cup moves against the base plate.
  • a further frame of airtight material preferably with a higher deformation resistance, is provided concentrically to the compressible frame for increasing the vacuum until the plastic films are welded.
  • a further frame of airtight material preferably with a higher deformation resistance
  • the Anpressrandes against the plastic films and against the welding wire with high pressure in the final phase must be evacuated so strong until both frames are compressed.
  • both the contact pressure during welding and the height of the vacuum in the packaging to be welded can be predetermined.
  • a particular embodiment is characterized in that the suction cup is selectively slidable over one of two base plates and the two base plates are each movable between the depositing position and a welding position.
  • a cold cut can be placed on a base plate, while the finished cold cuts on the second base plate by means of the suction cup to an evacuated, welded Pack is processed.
  • This design saves time and increases the efficiency of the evacuated slicing machine for the counter operation.
  • a membrane body is provided, which undergoes a spatial expansion with increasing evacuation.
  • the vacuum-expanding membrane pad additionally ensures that during the evacuation, air is spread between the two layers of film enveloping the sliced product from the center in the direction of the film edge in order to ensure as complete evacuation as possible.
  • a "squeezing" of the juice contained is undesirable.
  • the membrane body is connected via a free cross-section with the ambient air, preferably a shut-off device is provided.
  • the shut-off device can be controlled either manually by manual valve or automatically with solenoid valve and pressure sensor, the contact pressure.
  • Under the free cross-section can also be understood a hole in the suction cup, which can be kept with a finger when reaching the desired extent of the membrane.
  • an elastically compressible pad is provided, which preferably has a convex contour, with its thickness decreases from the center in the direction of the edge ,
  • This variant provides a similar function with simple means. If the pad is made of a particularly soft, sponge-like material, the pad can in the welding position - without slices and films - quite extend to the base plate.
  • FIG. 1 shows a side view of a slicing machine
  • Fig. 2 is a plan view
  • Fig. 3 as a detail one half of a suction cup against a base plate with Thomasgutusionn between plastic films
  • Fig. 4 the arrangement of FIG. 3 during evacuation and Fig. 5, the arrangement according to Fig. 3 and 4 during the subsequent welding of the evacuated pack.
  • a chain frame 4 is arranged with horizontally guided parallel chains, by means of The spikes (spikes) positioned on the chains pick up each clippings disc after the cutting operation and transport them near a depositing position 5.
  • An unillustrated racket throws the Thomasgutierin each in the direction of arrow 6 on a provided in the depositing position 5 base plate 7. As known, the Thomasgutusionn are overlapping in a row on the base plate 7 by varying the conveying path.
  • a carriage-like in guides 12, 13 provided in the direction of the depositing position 5 movable suction cup 14.
  • the guides 12, 13, which are realized by two rails, extending under the chain frame 4 through and limit the base plate 7 side.
  • the suction cup 14 itself points from a flat circumferential Anpressrand 15 starting on an upwardly shaped shell-like dome 16, which finally comes to lie like a bell over the cold cuts 10 (Fig. 3).
  • the Anpressrand 15 carries laterally guide rollers 17 which run in or on the guides 12, 13. If the suction cup 14, which has a reversing feed and return drive, not shown, moves from the retracted waiting position shown in Fig. 1 on the base plate 7, then approaches the suction cup 14 of the base plate 7, because the guides 12, 13 angled there are.
  • the base plate 7 has in its base a rectangular circumferential welding wire 18 or a welding band and further on the ground via at least one frame 19 (Figure 2) of compressible airtight material (such as sponge rubber).
  • Figure 2 of compressible airtight material (such as sponge rubber).
  • Fig. 3 two such airtight, compressible frame 19, 20 are shown in concentric arrangement.
  • the pressing edge 15 of the suction cup 14 finally touches the frame 19 (FIG. 4).
  • the suction cup 14 is connected to a vacuum pump 21 and to a vacuum vessel 22 via a valve 23.
  • the valve 23 solenoid valve with electrical control
  • the base plate 7 and the frame 19 vacuum chamber abruptly a negative pressure.
  • the consequence of this is a compression of the frame 19 against the deformation resistance.
  • the suction cup 14 approaches even more of the baseplate 7.
  • the compression of the second frame 20 eventually requires additional strain work and, therefore, a further increase in the vacuum.
  • the remaining air is thus removed from the area between the two plastic films 8, 9 and the cold cuts 10.
  • the height of the vacuum is determined here by the deformation resistance of the frames 19, 20 to be overcome.
  • the suction cup 14 After venting the vacuum chamber, the suction cup 14 jumps due to the expansion of the frame 20 and 19 and upon activation of the feed and retraction drive of the suction cup 14 this is raised backwards to the left and finally brought back into the waiting position (Fig. The vacuum-packed cold cuts can be removed. A new cold cuts is laid and the cycle can start again.
  • the base plastic film 8 can be laid by hand or with a sucking swivel arm on the base plate 7.
  • the covering plastic film 9 can be placed by hand or also fully automatically.
  • FIGS. 3 to 5 a membrane 24 is provided.
  • the diaphragm 24 arranged underneath the dome 16 is in its starting position.
  • the valve 25 is open.
  • air is extracted from the suction cup. Air flows into the membrane 24 via the opened valve 25. It can be seen from FIG. 4 that the membrane 24 is already in contact with the plastic film 9 in the middle of the packaging.
  • the membrane 24 applies more and more to the plastic film 9, while still extinguishing existing air from the cold cuts 10 out.
  • squeezing the juice out of the meat can be ensured by controlling the contact pressure of the membrane 24 by timely closing the air supply with the valve 25.
  • the interior of the membrane 24 communicates with a hose 26 and the valve 25 in connection.
  • the tube 26 and the valve 25 and a non-illustrated, compressible pad may be provided which according to the Membrane 24 in Fig. 4 has a convex contour to safely strip residual air from the center of the film 9 in the direction of the edge of the film 9.
  • the slicing machine has remained unchanged in its dimensions compared to the basic model without evacuating packaging device.
  • This counter unit should be operated within the customer's field of vision, so that the freshness of the ordered cut and the process of vacuum packaging are immediately visible to the customer.
  • a double-acting embodiment comprises guides 12, 13, which are about one third longer and with which the base plate 7 - and in Fig. 1 and 2 right next to this - a second base plate is rigidly connected.
  • the entire unit consisting of guides 12, 13, suction cup 14 and the two linearly juxtaposed base plates is linearly displaceable. This makes it possible to move back for evacuation by means of the suction cup 14 and for welding to the entire unit to the left, so that the free base plate is in the storage position 5. While the first pack is welded, a new cold cuts can be stored at the same time.
  • a slicing machine with such a double-acting embodiment can be used particularly efficiently.
