Definitions

  • the invention relates to a device for producing sacks, which can be transported transversely to their direction of extent by the device, according to the preamble of claim 1 and a method according to the preamble of claim 13.
  • Such devices are known and have been available on the market for a long time. As a rule, they initially comprise a separating device in order to separate a supplied hose into pieces of hose.
  • This tube preferably comprises woven fabric of stretched plastic tape, which may also be coated.
  • the isolated pieces of hose consist of two superposed material webs.
  • the hose pieces are taken over by at least one transport device in order to spend them in the individual processing stations.
  • One of these processing stations is the so-called bottom opening station.
  • at least one end of a piece of tubing is pulled open, so that a bottom can be molded onto this wound-up end.
  • both ends of a piece of hose are processed in this way.
  • a device with which such sacks are produced is in the DE 195 02 251 A1 disclosed.
  • the pieces of tubing are moved forward in the cycle mode, being transported flat lying transversely to their main axis, so that laterally arranged processing means can handle both ends of the piece of tubing.
  • the hose pieces are stopped.
  • the upper layer is raised at the ends of the hose piece by means of a nipple, so that a horizontally in the direction of the main axis slidable sheet between the two layers of material of the hose section can be retracted.
  • the lower material layer of the hose section is held in place by negative pressure on the table on which the hose section rests during transport.
  • the upper material layer is folded back by the insertion of the sheet, forming corner impacts on the outside of the upper material layer. After folding, the sheet is pulled back and transported the bag on. As a result, the hose pieces are successively taken over by a further transport device, which feeds them in a uniform speed, ie continuously, a bottom closure device.
  • said device has a number of disadvantages with respect to the fixation of the open bottoms. Particularly serious is the time required to fix the open floors within the opening station. According to the DE 195 02 251 A1 is intended to transport the piece of hose until after the open bottom is fixed. This period may even be an upper limit to the performance of the entire sack making apparatus.
  • pressing means act on the opened trays during the further transport, whereby, however, the folded edges have already been determined in a pre-breaking station.
  • a pressing means designed as a pressure roller pair for pressing the opened floors.
  • at least one means of transport is provided, with which the Hose piece after opening one end of this piece of hose and before the action of the pressing means in the transport direction (x) is further transportable.
  • the DE 0 698 687 shows a similar device.
  • the DE 1 273 315 discloses a still improved device which presses the second triangular pockets more reliable by a hold-down bar acts on the second triangular pockets.
  • the object of the present invention is therefore to propose an apparatus and a method for the production of sacks with which or with which the opened trays are to be fixed faster.
  • the object is achieved by a device with characterizing features of claim 1 and by a method having the features of the characterizing part of claim 13. Accordingly, it is provided, the pressure roller (23, 23 ') with the counter-layer a gap with an adjustable, but fixed gap After opening at least one end of the hose piece, this can thus be transported immediately further, so that space can be quickly created in the floor opening station for another hose piece to its at least one end to be able to open. Ultimately, with this measure, the performance, ie the number of bags completed per unit time significantly increase.
  • the pressing means is designed as a rotatable pressure roller.
  • Such pressure rollers have various advantages.
  • the DE 195 02 251 teaches to make forming dies lowerable and liftable. For this purpose, however, a great mechanical effort must be operated. In the cited document Druckstoffkolbenzylinderüen be proposed. Furthermore, it is in a device according to the DE 195 02 251 disadvantageous that the forming dies must have the shape of the Eckeinplo to work effectively. In a format change, therefore, the replacement of the forming dies is necessary. These disadvantages are reduced by the provision of pressure rollers.
  • a pressure roller The operation of a pressure roller is the following: The opened bottom is threaded under the pressure roller. The pressure roller can then exert a pressing pressure on the ground and fix it in this way. Such a roller does not need to be lowered or raised, which is why the mechanical effort for fixing the floors can be omitted. A nip roll can be placed near the bottom opening station so that the bottom has no opportunity to fold back. As soon as the bottom is fully opened, it can be fed to the pressure roller by further movement with the means of transport.
  • the invention has an effect if the hose pieces are not intermittently, as in the DE 195 02 251 A1 is described, but be transported continuously within the device for the production of sacks. If the mold punches proposed in the cited publication were to be adapted to a continuous transport, the mechanical outlay would even be much greater.
  • the axis of rotation of the pressure roller runs parallel to the extension direction of the hose pieces.
  • the open bottom of the tube pieces is thus guided by the transport under the pressure roller, wherein, as described above, the transport direction is transverse to the extension direction of the tube pieces.
  • the pressure roller may then be mounted stationary with respect to the device. It does not need to be moved relative to the manufacturing device during operation. This minimizes the mechanical effort.
  • the pressure roller extends at least completely over the entire width of the open end of a piece of hose.
  • the width means the width of the floor rectangle, which is often referred to as floor square, viewed in the extension direction of the hose section. This ensures that the pressure roller rolls on all sections of the folding edges of the Eckeinelle and thus optimally fixed the Eckeinelle and consequently the complete open end.
  • the width of the pressure roller should be greater than the width of the bottom rectangle of the bag with the largest possible producible on the device bottom width.
  • the present invention and in particular the latter embodiment, has particular advantages.
  • the pressure roller with the counter-layer forms a gap with an adjustable, but fixed gap, through which at least parts of the open bottom can be guided.
  • the gap size is adjustable but, if set, firm.
  • the pressure roller is then adjustable so that several superimposed layers of material, which are usually connected to each other via folding edges, are pressed. Overall, a very high contact pressure can be provided by such a fixed arrangement.
  • the pressure roller is rotatably mounted in at least one lever arm, which is itself pivotally mounted in the machine frame or in attachments of the machine frame is particularly advantageous.
  • the lever arm can be fixed, for example clamped, to an axle which can be firmly and non-rotatably connected to the machine frame.
  • the pressure roller can also be mounted in another way in a positioning device, with which the pressure roller is movable relative to the counter-position.
  • a positioning device with which the pressure roller is movable relative to the counter-position.
  • the pressure roller is mounted in at least one carriage, which is displaceable on rails.
  • Other adjusting devices are conceivable.
  • the counter-layer can be formed in different embodiments in different ways.
  • the counter-layer comprises a bearing surface on which the pieces of tubing rest during their transport through the device for making sacks. The open floors are thus pressed in the gap between the pressure roller and the support surface, the latter may be a table-like plate.
  • the counter-layer may comprise at least one counter-pressure roller. This counter-pressure roller is preferably rotatable in order to prevent a displacement of the material layers of the opened bottom against each other. But it is also conceivable, both embodiments mentioned to combine to provide a uniform contact pressure over the entire bottom width, even if there is a different number of material layers in the different areas.
  • the peripheral surface of the pressure roller at least partially has a steel surface or a rubberized surface.
  • the at least one counterpressure roller may also comprise such surface materials.
  • the drive can be a motor that drives a pressure roller and a counter-pressure roller.
  • the drive can also be responsible for the drive of the pressure roller upstream floor opening station.
  • the main drive of the entire device for the production of sacks can be used as a drive. Further drive configurations are conceivable. If pressure rollers and / or counter-pressure rollers are present at both ends of the hose pieces, the rollers can be driven at the respective end, independently of the rollers at the other end of the hose piece.
  • the Fig. 1 schematically shows individual steps for processing a fabric tube to bags, as done in bag making device 1.
  • the fabric tube 2 is fed to the sack manufacturing device 1. This advantageously takes place by unwinding the fabric tube forming a roll 3 in a unwinding device 4. Subsequently, the tube 2 experiences the so-called opening in the separation station 5.
  • the fabric tube is guided around an inner tool which separates the two layers, so that the layers, if they were glued together in one of the manufacturing steps of the tube, separate. Only with separate layers can it be ensured that the following production steps can be carried out properly. Afterwards, the separate material layers of the hose are put back on top of each other.
  • the fabric tube is now fed to the cross-cutting device 6, which separates the fabric tube into individual pieces of hose.
  • both ends of each tube piece are opened and the so-called bottom squares are laid.
  • valve station 9 a valve is placed and secured on one of the two open ends.
  • the open floors are now closed in the bottom closing station 10, wherein two tabs are placed on each other and permanently connected to each other, for example by welding.
