Definitions

  • the invention relates to a device for producing sacks of tubular material, which comprises woven plastic tape fabric, according to the preamble of claim 1, and a method for producing sacks according to the preamble of claim 11.
  • Such devices are known and have been available on the market for a long time. These devices typically include a tube forming apparatus for making and providing a tubular material. It may also be present only a Schlauchabwickelvorraum. This is usually equipped with a material wrap on which tubular material is wound. From this material wrap the material is usually withdrawn continuously in the longitudinal direction.
  • the fabric hose provided by the hose forming apparatus or by the hose unwinding apparatus is fed to the cross cutter, which separates the fabric hose into individual pieces of hose.
  • the pieces of hose are transferred to a transport device.
  • a change of the original transport direction in which the tube or pieces of tubing were transported in the direction of their longitudinal axes, takes place in a new transport direction, so that the tube pieces are no longer transported in the direction of their tube longitudinal axis, but transversely thereto, so that the ends of the hose pieces for the purpose of Anformung the floors laterally accessible are.
  • the original and the new transport direction of the hose or hose piece are perpendicular to each other.
  • the tubular fabric material which may also be coated, is singulated into pieces of tubing.
  • the tubing In the manufacture of tubing, the tubing is progressively advanced in its longitudinal direction by one length of tubing.
  • a compensation device in the form of at least one movable deflection bar is provided between the material winding and the separating device.
  • a piece of hose is separated from the hose, so separated. This is usually done with a cutting tool such as a knife.
  • Said material wrap often comprises a fabric tube made of a circular woven material. The tube produced on a round loom is flattened after its manufacture and provided with a coating, which ensures that parts of the hose piece can be welded together without the stretched fabric being damaged and losing its strength.
  • the hose forming apparatus forms tubular material by stacking the edges of the web of material and joining them together, for example by means of a plastic extrudate. In this process, both the flat web and the hose are transported in the longitudinal direction.
  • the tubular material consists of two superimposed material webs, which may each consist of several layers.
  • the said hose-forming device may additionally be capable of inserting gussets. Gusseted bags have advantages when stacked when filled. Producing tubing made of woven and coated sheet material has the great advantage that no coating material protrudes laterally beyond the edges of the flat tube, as is often the case when flat laid, tubular woven tubing is coated. Supernatant coating material leads often errors in the manufacture of bags from pieces of tubing.
  • the piece of hose produced in the manner described is taken over by at least one transport device in order to spend it in the individual processing stations. After separation, the pieces of hose are no longer transported in the longitudinal direction, but in the transverse direction.
  • transverse direction it is meant that the pieces of tubing are now transported 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.
  • the fabric hose provided by the hose-forming device is fed to the cross-cutting device, which separates the fabric hose into individual pieces of hose.
  • the pieces of hose are transferred to a transport device.
  • a change of the original transport direction in which the tube or pieces of tubing were transported in the direction of their longitudinal axes, takes place in a new transport direction, so that the tube pieces are no longer transported in the direction of their tube longitudinal axis, but transversely thereto, so that the ends of the hose pieces are laterally accessible for the purpose of molding the floors.
  • the original and the new transport direction of the hose or hose piece are perpendicular to each other. For this reason, the tube forming apparatus and the above-mentioned processing stations are also arranged perpendicular to each other.
  • a generic device is from the CH 425 434 A known, which comprises an unwinding, from which tubular material is unwound and singulated into pieces of tubing, wherein the tubular material is first transported in the tube extension direction. After separation, the pieces of hose are transported transversely to their longitudinal direction.
  • the vertical arrangement of the hose forming device to the processing stations is disadvantageous.
  • the floor space of production halls is usually rectangular and therefore such an arrangement is space consuming.
  • the US 3,871,270 discloses a bag-making device in which the transport direction in the tube-forming device and in the bottom-forming device are arranged parallel to each other. After separation of the tube into pieces of tubing, these pieces of tubing are rotated 90 degrees within another conveyor so that they can be transversely transported within the bottom forming device. This further transport device is mechanically very complex and also also requires a large footprint.
  • the object of the present invention is therefore to propose a device for the production of bags of tubular material, which can be constructed to save space.
  • the hose forming device conveys the tubular material along the tube longitudinal axis. Since the processing stations have to reach the ends of the individual pieces of hose, it is advantageous to the hose pieces transversely to the longitudinal axis to the processing stations transport. Therefore, it is provided according to the invention that at least one deflecting device is provided between the hose forming device and the bottom forming device, with which the tubular material is deflected before the cross cutting in a new transport direction, which extends at least partially transverse to the original transport direction.
  • the hose can be conveyed already in the direction corresponding to the position of the hose pieces, which is necessary for the subsequent processing of the hose pieces.
  • a hose unwinding device may also be arranged according to the invention.
  • a particularly preferred embodiment of the invention includes that the deflection device, with which the tubular material is deflected, in its position variable, in particular in the original transport direction of the tubular material is displaceable.
  • the edge layer of different widths of material hoses can be adapted to the cross-cutting or separating device.
  • the middle layer regardless of the hose width, is usually the same.
  • the transport device however, the hose pieces are detected on its front side edge, so that not the center line, but the leading edge, regardless of the hose width, must assume a constant position. This is achieved particularly easily by the displaceability of the deflection device.
  • a plurality of deflection elements are provided, which are variable in their inclination angle relative to the transport direction of the tubular web. Also in this way, the position of the leading edge can be adjusted.
  • the deflecting device can advantageously be a per se known air turning bar.
  • the air turning bar may include holes that are exposed to air, so that the tubular material can be guided without contact over the turning bar.
  • the separating device and the deflection device are vertically spaced from each other.
  • the deflection device is arranged above the separating device.
  • the deflection device can also be positioned below the separating device. This makes it possible for the hose delivery device and the further hose piece processing stations to be constructed or arranged directly one behind the other - in a line. In this case, the geometric hose and hose center line are in line, which also avoids unnecessary space consumption.
  • the transport direction of the tube by means of only one, in the transport direction of the tube obliquely arranged deflecting device is changed. It is particularly advantageous if the deflecting device is arranged above the separating device. By means of transport rollers whose axes of rotation are arranged transversely to the transport direction of the tube, the latter can be passed to the level of the separating device.
  • the hose-forming device comprises a storage device which is arranged in the transport direction of the hose in front of the deflection device.
  • the storage device With the storage device, tubular material previously generated by the tube forming device is storable.
  • the individual processing stations in particular the hose-separating device
  • the individual processing stations can be further supplied with tubular material without the sack production having to be stopped.
  • further tubing can be stored when the processing stations need to be stopped.
  • the hose-forming device comprises a winding with which the previously prepared tubular material can be wound into a winding.
  • the tube forming apparatus can operate "offline" - that is, without supplying tubular material to the processing stations.
  • the processing stations can also be fed by a unwinding device with tubular material.
  • the unwinding device comprises a coil of tubular material and is not connected to the hose forming device.
  • the material wrap may have previously been produced by the tube forming device.
  • the device for producing sacks can therefore be operated in two alternative ways of working.
  • the cross-cutting device is used directly with tubular material from the Hose forming device supplied.
  • the sack making device is supplied, as described above, by a separate tubing reel that can be produced by the hose forming device in the manner described.
  • the said components of the device for the production of sacks can be operated with the greatest possible flexibility. This flexibility is particularly required, for example, during maintenance work on individual components of the device for producing sacks.
  • the hose delivery device comprises a device for detecting material defects. Due to the device for material defect detection faulty hose areas are recognizable.
  • the faulty hose areas can be leaky seams. These may arise, for example, in the case of faulty bonding of the material web edges in the hose forming device.
  • defective hose areas can also be fabric defects or coating defects of the flat material, which is made into a tubular material. Even a wrong hose width can be recognized as a defective hose area.
  • a separation separator is provided behind the tube separating device. With this separating softener pieces of hose, which have faulty areas, can be discharged.
  • a control device which can be supplied via a suitable data line data from the device for material defect detection.
  • This information is information about the defective areas of the tubular material described above.
  • the device for detecting material defects is advantageously arranged in front of the separating device. Behind the separating device is advantageously located directly the separation.
  • the Ausscheideweiche is activated by the control device, when the device for material defect detection detected a defective area (and this the control unit transmitted) and the respective tube section has been singled.
  • the transport device now takes the elimination separator the hose section.
  • the defective piece of hose is discharged before it can reach the individual processing stations and can be processed into a sack. With this timely discharge defective hose pieces can therefore be saved a lot of energy and time, because faulty hose pieces are not processed until the bag.
  • the Fig. 1 schematically shows individual steps for processing a fabric tube to bags, as done in sack making devices 1.
  • the tube forming device 13 comprises a coil 3 containing sheet material 14.
  • the web-shaped material 14 is fed in the transport direction x 'a hose forming portion 28.
  • the web-shaped material is folded back on itself in a known manner and the edges glued or welded together, so that a material tube 2 is formed.
  • the tube 2 undergoes the so-called opening in the Opening station 5.
  • the fabric hose is guided around an inner tool around which separates the two layers, so that the layers, if they were glued together in one of the manufacturing steps of the tube 2, separate. Only with separate layers can it be ensured that the following production steps can be carried out properly. Subsequently, the separate material layers of the tube 2 are placed again on each other.
  • the tubular material web 2 is a deflection device, preferably at least one turning bar 17, supplied.
  • the turning bar 17 is displaceable in the direction of the double arrow 15.
  • the material hose 2 is directed from the original transport direction x 'in the transport direction y and fed to a cross-cutting device 6, which separates the fabric tube into individual tube pieces 16.
  • the tube pieces 16 are transported transversely to their tube longitudinal axis in the transport direction x, so that the ends of the tube pieces for the purpose of Anformung the bottoms of the respective processing stations are laterally accessible.
  • the transport direction x 'of the tubular material 2 and the transport direction x of the tube piece 16 are parallel.
  • 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.
  • the conclusion of the actual Sackherstellreaes forms the application of a ground 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 FIG. 2 shows a plan view of the turning bar 17.
  • the turning bar can be rotatably mounted on a holder 24 on a support frame 18.
  • the holding frame 18 is in the embodiment shown here in a plane which is parallel to the direction of movement of the tubular material 2. Below the holding frame 18 slides 20, 27 are mounted, which engage in rails 19 ( FIG. 3 ).
  • the holding frame 18 is movable by means of the carriages 20, 27 on the rails 19.
  • the carriage 27 is extended in the direction z.
  • a spindle nut is incorporated, in which a spindle 21 engages.
  • the spindle 21 is rotatable by means of the motor 23.
  • the holding frame - By rotation of the spindle 21, which engages in the spindle nut of the extended carriage 27, the holding frame - and thus also rotatably mounted on the turning bar 17 - in the direction x 'and -x' movable. Due to the mobility of the turning bar parallel to the direction of movement of the tubular material 2 (in the direction x 'and -x'), the edge position of different widths of material hoses can be adapted to the cross-cutting or separating device 6.
  • the spindle motor 23 is connected to a control device 25 via a suitable data line 26. In the control device, the width dimensions of the material hoses to be processed can already be stored. However, manual entry of these width dimensions is also possible.
  • control device 25 controls the spindle motor 23 due to the width dimension of the tubular material such that the Turning bar 17 in the direction x 'is moved until the edge position of the tubular material is adapted to the cross-cutting or separating device 6.
  • FIG. 4 shows the side view of a hose forming device 13.
  • the web-shaped material 14 is unwound from a roll 3 and fed to a hose forming region 28 not described in detail, in which 28 the web-shaped material 14 is processed into tubular material 2. Subsequently, the tubular material passes through guide rollers 22 to the turning bar 17. Alternatively, even in the so-called off-line mode web material can be wound on a winding 4.
  • the material hose 2 is guided by means of the turning bar 17 from the original transport direction x 'in the transport direction y and fed to a cross-cutting device 6, which separates the fabric tube into individual tube pieces 16. You can use the FIG. 4 recognize that the turning bar is in a plane above the cross-cutting device.
  • the separating or cross-cutting device 6 can also be supplied by a separate material winding 29 with tubular material.
  • the bag making apparatus can be operated in two modes of operation. In the so-called “inline mode”, the cross-cutting device 6 is supplied directly from the hose-forming device 13 - via the turning bar 17 - with web-shaped material. In the so-called “offline mode”, the cross-cutting device is supplied by a separate winding 29 with tubular material. The tubular material may have previously been made by the tube forming device 13 and wound into a coil 4. In this case, the bag 4 would then be brought to the position of the roll 29 for bag production.
  • both sides of the machine can be reached by the operators of the bag making device without having to circulate the entire machine.
  • This is particularly advantageous because with the succession of the tube forming device 13 and the individual piece piece machining stations the overall machine length is enlarged.
  • the position of the passage directly next to the separating or cross-cutting device 6 is advantageous because the operator can more easily access the cross-cutting device 6 and, for example, can eliminate material compression.
  • both tubing wraps 4 and 29 can be reached by the operator. This is advantageous both in the case of errors occurring as well as in a Materialwickel Touch.
