Definitions

  • the invention relates to a device for the continuous destacking of web-like goods according to the preamble of claim 1 and a method for the continuous destacking of web-like goods according to the preamble of claim 10.
  • Destacking means the layered and zigzag-shaped depositing of web-like goods on grates, pallets or transport trolleys.
  • the goods are passed through a reciprocating table arm, which places the goods in a zigzag shape on the support.
  • a slidable or mobile table table for example in the form of a carriage, is generally used as the base.
  • the underlay is removed, the stacked goods are unloaded and the empty table table is positioned again under the stacker.
  • the known arrangements all have the disadvantage that the machine upstream of the scraper must be stopped during the unloading process of the stacked goods. Due to the constant interruptions, the productivity of the machine upstream of the scraper is severely impaired. On the one hand, the machine is not in use for a relatively long period of time, on the other hand, frequent stopping complicates the design of the machine and shortens its service life.
  • a device for folding and cutting paper webs is known from US Pat. No. 4,908,010, in which the subsequent paper web is paneled onto the knife during the cutting process, as a result of which the device can be operated continuously. Problems arise in particular when used with textiles if the cutting knife tears parts of the fabric out of the stack when it is pulled back. The transfer of the stack from the knife to the support table can be complicated in such devices.
  • the aim of the invention is to avoid the disadvantages of the known, in particular to provide a device for the continuous destacking of web-like goods, which eliminates the need to stop the machine upstream of the destacker and which enables reliable destacking.
  • Another object of the invention is to provide a method for the continuous destacking of web-like goods, which allows destacking without stopping the machine upstream of the destacker and which enables a uniform destacking.
  • the device according to the invention for stacking web-shaped Goods consist of a table table and a table arm arranged above it and have additional auxiliary storage means for continuous stacking.
  • the auxiliary storage means can be inserted in an insertion direction between the table arm and the table table and are provided with an insertion end face.
  • the insertion end is understood to mean that part of the auxiliary storage means which is first inserted between the table arm and the table table.
  • the auxiliary storage means are provided with at least one recess which extends in the direction of insertion from the insertion end. Thanks to these recesses, the contact area between the auxiliary storage means and the stacked goods can be reduced.
  • the auxiliary storage means consist of a rake.
  • the recesses are formed by the spaces between the individual bars of the rake.
  • flat auxiliary storage means which have only one or two cutouts which extend in the insertion direction.
  • the table table is also provided with upwardly directed support elements which are complementary to the recesses in the auxiliary storage means so that they can penetrate them.
  • the table table can be raised (or the auxiliary storage means lowered) so that the carrier elements penetrate the cutouts of the auxiliary storage means and support the stacked goods.
  • the auxiliary storage means can then simply be pulled out between the stack of goods and the table, since they are no longer in direct contact with the web. It is for the functioning of the inventive Device the number and shape of the recesses of minor importance. It is essential that the cutouts extend from the insertion end of the auxiliary storage means in the insertion direction.
  • the carrier elements of a particularly advantageous table table are also movably arranged.
  • the carrier elements can be designed, for example, in the form of circumferential bands. These belts can be moved to unload the table so that the stack of goods can be brought from the table to a storage position next to it. In such cases, the carrier elements perform a function both when the stack of goods is taken over from the auxiliary storage means and when the goods are handed over for further processing, for example for packaging or transport.
  • the sheet-like goods are guided through the pendulum-like movable table arm onto the table table. Due to the pendulum movement of the table arm, the sheet-like goods are stacked on the table table in layers, zigzag-like.
  • the auxiliary storage means are inserted between the stack of goods and the table arm.
  • the auxiliary storage means take over the function of the table table for a certain time.
  • the table with the stack of goods can therefore be removed and unloaded from the stacker without having to interrupt the destacking process.
  • the table When the table has been emptied, it can be repositioned directly below the auxiliary storage means and the new stack of goods placed on the auxiliary storage means can be transferred to the table.
  • the stacking device also has a cutting device with which the stacked goods are unloaded before the table is unloaded can be separated from the next lane.
  • a particularly advantageous exemplary embodiment results if the table table and / or the auxiliary storage means are arranged such that they can be adjusted in height. It can thereby be achieved that the surface of the stacked goods is always kept at the same height in relation to the table arm. Both the table table and the auxiliary depositing means are advantageously moved down during the destacking.
  • the boarding device also has a feed unit for covering the auxiliary storage means with a flat base.
  • the auxiliary storage means in particular a rake, are covered with a flat surface by the feed device.
  • the underlay can preferably consist of cardboard.
  • a carton can also be placed on the top of the stacked goods with the feed unit. This is preferably done shortly after the auxiliary storage means have taken over the function of the table table.
  • a particularly advantageous exemplary embodiment results if the table table is arranged to be displaceable from a table position into an unloading position.
  • the method according to the invention for the continuous destacking of web-like goods is characterized in that the board table is replaced by auxiliary storage means during the unloading of the boarded goods.
  • a first step web-shaped goods are usually placed on a table table.
  • the auxiliary storage means take over the function of the table table.
  • the table with the stacked goods can be removed from the stacker without having to interrupt the destacking process and the machine upstream of the stacker must therefore be switched off.
  • the goods are placed on the auxiliary storage means.
  • the table table is returned to its original position and takes over the stack that was stacked on the auxiliary storage means. In this way, a continuous stacking cycle is created, which eliminates the need to stop the upstream machine.
  • the auxiliary storage means have cutouts which extend from the insertion end in the insertion direction.
  • the auxiliary storage means also have at least one support element projecting upwards.
  • the table table is raised and / or the auxiliary storage means is lowered, so that the support elements of the table table penetrate the cutouts of the auxiliary storage means from below and lift the goods placed on the auxiliary storage means.
  • the auxiliary storage means are relieved of the stored goods and can simply be pulled out laterally between the carrier elements.
  • the stacked goods are separated from the subsequent web shortly before the table table is replaced in its function by the auxiliary storage means.
  • a single stack is always initially stacked on the auxiliary storage means and subsequently handed over to the table.
  • a particularly advantageous exemplary embodiment of the method results if the table table is lowered during the destacking, so that the top level of the stack of de-clad goods is kept at a constant height. With such a method, a particularly regular layering of the web-like goods is achieved due to the constant distance between the table arm and the stack.
  • the table is lowered during destacking, it is advantageous to lower the auxiliary storage means during the destacking.
  • the auxiliary storage means are located before they take over the function of the table slightly above the upper surface of the stack of goods lying on the table. After taking over the function of the table table, the auxiliary storage means are also lowered in such a way that the upper level of the stack placed on them remains at a constant height. After emptying, the table table is positioned in such a way that it comes to rest in the auxiliary storage means from below. The transfer of the stacked stack from the auxiliary storage means to the table is particularly easy.
  • a particularly simple unloading of the table table is obtained if the table table can be moved from a table position to an unloading position for unloading the stacked goods.
  • the auxiliary storage means are inserted between the table arm and the upper level of the stack on the table table before the table table is unloaded.
  • the auxiliary storage means are covered with a flat, stable base before they take over the function of the table table.
  • the web-shaped goods are therefore not stacked directly on the auxiliary storage means, but on a support lying thereon.
  • the stacked goods remain on the fixed documents during the transfer to the table table and the unloading process from the table table.
  • the use of such a solid support ensures that the bottom layer of the stacked goods remains flat even when the auxiliary storage means are pulled out from under the stack.
  • the solid base plate offers protection against wrinkles, crumpling or tearing, but also against dirt through the auxiliary filing means.
  • FIG. 1 shows a device 1 for stacking sheet-like goods on a table table 2.
  • the device 1 has a pendulum-like, swingable table arm 3 for depositing the sheet-like goods in zigzag-shaped layers on the table table 2.
  • the zigzag-shaped stored goods form a stack of goods 4.
  • the device 1 also has a cutting device 6 for separating the stack of goods 4 from the subsequent web-shaped goods and auxiliary storage means 5.
  • the auxiliary storage means 5 are horizontally displaceably attached to a height-adjustable bracket 10.
  • the auxiliary storage means also have cutouts 15 (only indicated schematically in FIGS. 1 to 5), which extend from the insertion face S of the auxiliary storage means 5 in the insertion direction R.
  • the table table 2 is also arranged to be adjustable in height.
  • the auxiliary storage means 5 can be inserted horizontally between the upper level of the stack of goods 4 and the table arm 3.
  • the device 1 also has a feed device 11 for covering the auxiliary storage means 5 with flat, stable documents 8.
  • FIG. 1 represents the initial step of a table cycle.
  • a table cycle is understood to mean the placing of a stack of goods 4 on the table table 2 with subsequent emptying of the table table 2.
  • the sheet-like goods are placed with the table arm 3 in a zigzag shape on the table table 2, while the table table 2 is lowered.
  • the lowering speed is selected so that the upper level of the stack of goods 4 placed in relation to the table arm 3 remains at a constant height.
  • the auxiliary storage means are supplied with a feed device with stable, flat documents 8 documented.
  • FIG. 2 shows the device from FIG. 1 shortly after the height H of the stack 4 deposited on the table table 2 has reached a desired value.
  • the auxiliary storage means 5 are inserted horizontally between the stack of goods 4 and the table arm 3 shortly after the stack of goods 4 has been separated from the subsequent web by a cutting device 6.
  • the subsequent web of material is now placed in a further stack of goods 4 'on the auxiliary storage means 5 or on the base 8 lying thereon.
  • the height-adjustable holder 10, to which the auxiliary storage means 5 are attached, is lowered in such a way that the upper level 13 'of the stack of goods 4' placed on the auxiliary storage means 5 'remains at a constant height with respect to the table arm 3.
  • the table table 2 is moved with the goods stack 4 from a table position T into an unloading position E (see FIG. 3).
  • the panel table 2 can be mounted on a trolley 12.
  • the upper level 13 of the stack of goods 4 can be covered with a flat support 8 'made of cardboard after the auxiliary storage means 5 take over the function of the table table.
  • the stack of goods is limited on both sides.
  • FIG. 3 shows schematically how the stack of goods 4 together with the base 8 is removed from the stacking table 2, while the next stack of goods 4 'is placed on the auxiliary storage means 5.
  • the table table 2 is moved back to its original position.
  • Figure 4 shows how the table 2 is positioned directly in the auxiliary storage means 5.
