Definitions

  • the invention relates to a method for changing the transport direction in a transport device of flat workpieces, in particular hose sections, according to the preamble of claim 1 and a device according to the preamble of claim 5.
  • Such methods and devices are often used in sack making apparatus in which pieces of tubing are singulated from a tube web which are then further processed into sacks.
  • the tube web consists of a fabric tube.
  • the tube web is also understood as a juxtaposition of flat workpieces, which are to be separated. But it is also possible to supply already isolated pieces of hose of the device.
  • hose pieces are known and available for a long time on the market.
  • these devices initially comprise a separating device in order to separate a supplied fabric hose, which may also be coated, into hose pieces.
  • hose pieces consist of two superimposed material webs, which can each consist of several layers.
  • the tube is advanced cyclically in its longitudinal direction in each case by a length of hose piece in a first transport direction. The feed takes place in the direction of the tube axis. Subsequently, a piece of hose is separated from the hose, so separated. This is usually done with a cutting tool such as a knife.
  • a cutting tool such as a knife.
  • other separation methods and the associated facilities are conceivable.
  • each tube piece produced in this way is taken over in the device for changing the transport direction of at least one transfer device.
  • This transfer device is arranged downstream of a transport device, with which the pieces of hose can be brought into the individual processing stations. Transfer device and transport device can be combined to form a single transport device.
  • transverse direction it is meant that the pieces of tubing are now transportable transversely to their longitudinal extent so as to obtain unimpeded access to both ends of the pieces of tubing in the further steps of making bags.
  • a previously separated piece of tubing is fed transversely to its longitudinal axis by means of a suitable means of transport (for example double belt conveyor) to a pre-breaking station.
  • a forming die is lowered perpendicular to the transport direction of the hose pieces on the hose pieces.
  • the corner folds of the opened bottom of the sack, which is formed in the subsequent bottom opening station, are later located on the folded edge created in this case.
  • a valve is placed on the open bottom on a bottom opening in the valve dispensing station.
  • the bag is later filled with a suitable filling member.
  • Zulegestation the bottom opening of the bag is folded, so that subsequently in the ground cover sheet station by welding the bottom opening thereof with a bottom cover sheet of the bag is completed.
  • the transport device which holds the pieces of tubing from the support surface onto which the pieces of tubing were discharged, takes over and transversely transported to the longitudinal axes and supplies to the processing stations.
  • the piece of tubing Before a piece of hose can be taken over by a conveyor in the transverse direction on its transverse transport plane, the piece of tubing must first rest with its side region on the transverse transport plane, so that it can be detected by a so-called transfer device, such as a driving shoe.
  • This driver leads the hose piece to a conveyor - for example, a conveyor belt - which then brings the hose piece successively to the individual processing stations.
  • this transport plane often includes interference edges, against which the bag is pushed or pushed. As a result, the bag is compressed, possibly even damaged and a subsequent, proper onward transport of the bag is difficult.
  • the object of the present invention is therefore to propose a device for changing the transport direction, which reduces the above-mentioned disadvantages.
  • a following flat workpiece is advanced at least by a certain distance ( ⁇ z), while the workpiece in progress continues to move in the second transport direction (x) by a distance ( ⁇ x) which is smaller than the workpiece width (B) is transported.
  • the workpiece running ahead can now be transported away from the transfer device in the second transport direction (x). After a transport distance which is smaller than the workpiece width, the following workpiece can be advanced in the first transport direction (z).
  • the time required for the advance workpiece to be completely removed from the support by the transfer device can thus be used to further advance the hose and to produce the following length of hose by severing it from the hose. So it does not have to wait until the forward running workpiece has completely released the support surface. In this way, the subsequent workpiece can be transported immediately in the second transport direction (x) of the transfer device when the forward running workpiece has been carried away. The distance between the two workpieces can therefore be kept very small if necessary. In the same time interval, a larger number of workpieces can be removed from the transfer device compared to the method according to the prior art. After removal, the workpieces, so the pieces of hose, to bags processed, so that each time interval, a larger number of bags can be completed.
  • the workpiece ahead should still fully cover the interfering edges when the subsequent workpiece passes over the interfering edges. But it is not harmful if the workpiece already partially releases the interference edges.
  • the feed of the subsequent workpiece can start immediately, as soon as the transfer device has taken the advance running workpiece. If the leading workpiece releases the interfering edges completely, the following workpiece should already be advanced so far that it has already covered the interfering edges with its leading end.
  • the workpiece in advance is transported further by a distance ( ⁇ x) which is smaller than the workpiece width reduced by the distance of the ends of the interfering edge facing the workpieces from the leading side edge of the workpiece during its transport in the second transport direction.
  • parts of the preceding workpiece and / or at least part of the following workpiece is displaced by means for displacement relative to the plane in which the workpiece lies, the direction of displacement comprising a component which is orthogonal to this level runs.
  • the side edge, which runs ahead in the transport in the second transport direction slightly raised.
  • the hose piece can thus contactlessly over the interference edges be guided. This is particularly desirable when there is no advance workpiece that could cover the clutter edges.
  • the absence of a workpiece occurs, for example, when a workpiece is ejected from the production process due to an error or when production is started.
  • the present invention also relates to a device for changing the transport direction of successive workpieces.
  • a device achieves the abovementioned object by means for changing the spatial position of a flat workpiece with which the following flat workpiece can be advanced by a specific distance ( ⁇ z), while the workpiece ahead is moved by the transfer device by a distance ( ⁇ x), which is smaller than the workpiece width, in the second transport direction (x) is further transportable.
  • Part of such a device may for example be a feed device, which then already advances the hose or the already isolated piece of hose, while the leading piece of tubing still covers said transport plane, in particular Störkanten.
  • the movements of the two flat workpieces are coordinated, for example, by means of a geared connection between the feed device and the transfer device and / or by means of a control or regulating device.
  • the vote is made so that the transported in its longitudinal direction hose piece, at least almost, has reached its takeover position, while parts of the advance hose section still covers areas of the transport plane.
  • the means for changing the spatial position include means for displacing the end of the flat workpiece and / or the leading end of the following workpiece relative to the plane in which said ends are initially located, wherein the direction of the displacement comprises a component which is orthogonal to the plane.
  • the idea of this inventive development is thus, for example, the end of the flat workpiece, in the present case, the trailing end of a piece of tubing, out of the plane in which this end and the leading end of the subsequent workpiece are initially to bring out.
  • the subsequent workpiece may be the tube, from which only later, after one of said ends was brought out of said plane, is singulated into a piece of tubing.
  • the plane from which one of the two said ends is displaceable out may be defined by a support plane on which the two ends are placed or rest.
  • This support plane may be a component of a cutting device with which a piece of tubing is separated from the advanced tube, which, as already described, can be the subsequent flat workpiece. After this separation process, the severed tube section represents the flat workpiece, while the remaining tube then represents the subsequent flat workpiece. It it is clear that the cut produces the end of the flat workpiece and the leading end of the subsequent flat workpiece.
  • the support plane can therefore be the counter-position of the cutting blade.
  • the support plane comprises a groove which extends transversely to the longitudinal axis of the workpieces. In this groove, the cutting blade can be performed during the cutting process.
  • the device according to the invention thus ensures that the leading end of the tube or the already isolated piece of tubing is guided on or above the leading piece of tubing and can not touch the transport plane.
  • various technical elements are advantageously provided, which are explained in more detail below and in the physical description.
  • a pusher element is provided, with which the end of the flat workpiece, so for example, the end of the hose piece, in a region below the plane on which the end initially rests, can be pressed.
  • This area can be a free space at the side or below the support level.
  • the support plane viewed in cross-section, hook-shaped profile, so that below the said support plane, a free space is arranged.
  • the pusher element can then be arranged so that it can reach into this free space.
  • the pusher element may comprise a pneumatic piston cylinder, with which a pusher finger or a pusher bar is movable.
  • the pusher finger or the pusher bar then come into contact with it in an area of the hose piece, this area not resting on the level. If the pusher element is moved, the end of the hose piece thus flips off and slides along a side surface of the support element comprising the support plane until the end reaches the free space and aligns itself again due to restoring forces.
  • said free space wherein the pusher element is advantageously arranged so that the restoring forces are still supported and the hose piece as straight as possible aligns. This avoids errors in the formation of a bottom at this end of the hose piece.
  • the said device comprises at least regions of the support surface, which regions are displaceable or adjustable relative to the transfer device and / or to its transport surface.
  • the first piece of tubing When starting a machine, such as a bag making machine, which comprises the device according to the invention, the first piece of tubing naturally has no leading piece of tubing, which could cover the interference edges. Accordingly, it is provided that the first piece of tubing is guided on a displaced or displaced support surface, while it is sufficient for the subsequent tubing pieces or for the subsequent tube that they are discharged on the advancing piece of tubing, while the support surface remains in a rest position.
  • a so-called "first piece of tubing” can also occur during production if a piece of tubing is removed from the transport path immediately after its separation, which can take place if there is a defect in the piece of tubing, for example a material defect. Such a piece of tubing no longer needs to be further processed into a bag if it subsequently has to be treated as broke due to the defect.
  • the support surface can be moved to a position in which it is located above the transport plane, so that the transport plane is shielded for the hose piece to be pushed forward.
  • At least areas of the support surface are designed height adjustable.
  • support surface is meant that surface on which the bags rest during their transport path in their longitudinal direction.
  • a height-adjustable support surface can thus be moved, for example, orthogonal to the transport plane of the transfer device.
  • the movement can also be of any kind, the movement direction comprising an orthogonal component.
  • the support surface facing the transfer device is particularly advantageous if the height-adjustable areas of the support surface facing the transfer device.
  • the support surface is divided into two, wherein the transport plane of the transfer device facing part is adjustable in height or displaceable or movable.
  • the height-adjustable regions of the support surface are pivotable about a rotation axis which runs parallel to the first transport direction.
  • the height-adjustable support surface is folded up, so to speak, from the transport plane and encloses an angle with this plane.
  • This is advantageous because the piece of tubing is thereby bent up along a line parallel to its direction of extension and accordingly the parts which protrude laterally beyond the folded-up region of the support surface do not extend very far down but are rather kept horizontal. Therefore, the adjustment angle does not need to be particularly large.
  • the height offset between the height-adjustable support surface and the transport plane can be 10 mm, if the hose piece with about one quarter to one third of its surface laterally beyond the support surface protrudes.
  • the adjustment angle is advantageously between 0 ° and 45 °, but preferably between 10 ° and 20 °.
  • the device for changing the transport direction of the sacks for adjusting the height-adjustable regions comprises a suitable drive device.
  • This drive device may be a reciprocating cylinder, preferably a piston-cylinder unit operable with compressed air.
  • a piston-cylinder unit which can be operated with compressed air has the advantage of rapid adjustability.
  • 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 is advantageously done by unwinding a fabric tube forming a roll 3 in a unwinding device 4. Subsequently, the tube 2 experiences the so-called opening in the opening 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 2 is now fed to the cross-cutting device 6, which separates the fabric tube into individual flat workpieces or hose pieces 22.
  • both ends of each flat workpiece 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.
  • the conclusion of the actual Sack manufacturing process forms the application of a bottom cover sheet on the floors in the cover sheet station 11.
  • the cover sheets can also be welded.
  • the finished bags are then placed on the bag stack 12 and transported away from there on unspecified manner.

  • the separated piece of tubing 22 is taken from the transfer device 24, which is either already the actual transport device for transferring the tube pieces 22 in the individual stations to form sacks or the pieces of hose to the actual Transport device transfers.
  • Two successive pieces of hose 22 are transported in the direction x spaced from each other. This spacing is achieved in that the transfer device, which may comprise at least two transport belts 25, only detect the hose pieces 22 with contact elements 26 which are arranged at regular intervals on the transport belt. However, it is sufficient to detect the tube pieces 22 in the region of the side edges 18, which represent the leading edges during transport in the direction x.
  • This transport table 20 is, as can be seen, divided into two, wherein the two parts are displaceable relative to each other in the direction z. In this way, the transport table can be adapted to different hose section lengths. However, this has the consequence that the tube 2 would collide with its front edge 14 during the feed against the inner edge of the right table part.
  • the transport table 20 may, however, by design also include further cuts 27 which may form interference edges.
  • the support surface 13 is divided into a fixed part and a height-adjustable part 15.

  • a discharged tube section 22 is shown, which rests on the support 13 and the height-adjustable region 15. Just before this piece of hose 22 is taken by the contact elements 26, the height-adjustable portion 15 must be lowered. After the contact elements 26 have grasped the tube piece 22 and have already pulled it forward in the direction x for a short distance, the tube 2 can already be advanced again by means of the feed device 19. In the FIG. 4 this is shown. It can be seen that, with further preference of the tube piece 22, this part of the transport table 20 covers, so that the tube 2 can be advanced without interference and damage.
