Definitions

  • the invention relates to a device for producing sacks of pieces of hose, which preferably comprise woven fabric of stretched plastic tape according to the preamble of claim 1 and a method according to the preamble of claim 11.
  • the result was the task to improve the apparatus and method for the production of sacks in such a way that the bursting of filled bags is avoided.
  • the object is achieved by a device according to claim 1 and a method according to claim 11.
  • a transfer device with which areas of both walls of one end can be moved by more than 90 degrees around the Bodenfalzkante.
  • This device serves to fold back the end of the piece of tubing around the fold edge.
  • an embossing element and a counter element act on the end of the tube piece, wherein these two elements are in touching contact with the same wall of the tube piece.
  • the two elements act on the two different sides of the fold line.
  • the tube piece ends are folded over in the regions of the fold lines by 180 degrees and pressed against each other, so that the fold line is formed stronger.
  • the folding by means of the transfer device can serve to already convert the hose piece end by almost 180 degrees, so that the hose piece end without interference enters the area between embossing element and counter element.
  • the present invention was based on the finding that the embossing element according to the WO 2010/054955 With its rather sharp edge, the fabric has been badly damaged, so that it could no longer withstand the burdens of falling and is torn.
  • the embossing device according to the present invention acts only by applying a strong pressure to the folding line. In this case, the embossing element and counter element bear against the sharp edge with a significantly larger surface on the hose piece, so that damage and thus weakening of the fabric are avoided.
  • no disadvantages have become apparent to which the said transfer device substantially contributes.
  • the embossing element and the associated counter element comprise rollers.
  • the hose piece end runs, wherein the fold line preferably extends centrally of the rollers.
  • the embossing element and / or the counter element is associated with a drive, with which said element or the two said elements are driven at a peripheral speed which is greater than the transport speed of the hose pieces.
  • This slightly greater speed is referred to as "overfeed".
  • the drive can be an independent motor for the embossing element and / or the counter element, which can be synchronized with the main drive of the device.
  • both elements can be driven by its own drive.
  • the drive can also be done by the main drive of the machine, which preferably also drives the transport device for the hose pieces. Between the drive and the said elements then a transmission gear is provided.
  • the overfeed serves to tighten the length of tubing in the direction of transport, so that no wrinkles occur and these may be imprinted into the tubing.
  • the drive is on the counter element.
  • Embossing element and counter element can be provided to produce the frictional engagement on their surfaces with O-rings, which are raised relative to the peripheral surfaces.
  • the embossing element or the counter element can be adjusted with a force applying device against the other element.
  • the element which can be subjected to a force is preferably the embossing element.
  • the engageable element is preferably mounted in one end of a lever arm, on the other end of the Kraftbeaufschlagungs nails acts.
  • the force application device may be a spring element, a piston-cylinder unit or a simple mass, which is under the influence of gravity include. By a suitable choice of force, the fold line can be impressed sufficiently strong, without the tissue is damaged.
  • a folding element In order to set the folded edge before the embossing device acts on the folded edge, a folding element is provided, which has a folding edge defining the working edge. This working edge runs parallel to the transport direction of the hose pieces.
  • a further guide element is provided as part of the transfer device, with which the end of the hose piece can be folded around the working edge of the folding element. In this way, the end of the tube piece can already be largely folded back on itself.
  • the folding element extends wedge-shaped up to the folded edge of the hose piece.
  • the guide element is arranged inclined to the transport direction of the hose pieces, wherein it overlaps with the folding element in the course of transport.
  • the folding element is associated with a tension element, with which causes the hose piece material is pulled against the working edge of the folding element, so that the folded edge is formed at the predetermined position of the hose piece.
  • the tension element may be a roller whose axis of rotation is inclined both against the extension direction of the hose piece and against the transport plane thereof. The pulling element can be acted upon by a force, so that it is pressed against the folding element.
  • 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 of a fabric 3 forming a fabric tube in a unwinding device 4. Then, the tube 2 can experience the so-called opening in the opening station 5. In this case, the fabric tube is guided around an inner tool, which separates the two layers from each other, so that the layers, if they were glued together in one of the manufacturing steps of the hose, 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 ground rectangles 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 details of a bottom opening station 8 in a device according to the invention
  • the tube pieces 13 are transported flat by means of a transport device in the direction x on the surface of a support 14, for example on the surface of a table, ie substantially horizontal.
  • the transport preferably takes place at a uniform speed, ie in a continuous transport.
  • To open one end 15 of the tube piece this end is first brought from the horizontal position to a vertical position. To allow this folding, the hose piece must be counteracted.
  • the hose piece 13 is threaded under a folding element representing the counter position.
  • This folding element 16 is firmly attached to the machine frame or on the support. This means that the tube pieces 13 move relative to the folding element.
  • an additional transport device for example a conveyor belt 30, is provided below the folding belt (see FIGS. 6 to 9 ).
  • a conveyor belt 30 In the region of the folding element 16, one or more rollers may be provided to press the respective piece of hose to the conveyor belt 30 can.
  • a guide element 17 for example a baffle.
  • This baffle is shaped that the end 15 of the tube piece 13 beyond the fold line 27 (which represents the bottom center line) is successively brought into a vertical position.
  • the tube piece 13 passes to the actual bottom opening device 18, which is shown only schematically in this figure.
  • the tube piece passes through the embossing device 26.
  • the end 15 of the tube piece 13 is further transferred by one or more guide elements 25, so that it is folded back onto the tube piece.
  • the folding back particularly concerns the area near the fold line, while the other areas may remain in a vertical position. This is particularly advantageous because the entire end must be in a vertical position again for the bottom opening.
  • the tube piece 13 passes the pair of rollers, which is formed from a stamping element 28 and a counter-element 29.
  • the opening of the second end 15 'of the tube piece 13 takes place in the same way.
  • the embossing device is the same.
  • the processing of the second end 15 ' is, however, offset for processing the first end 15.
  • the first end is already opened in the bottom opening device 18, while the second end 15' is guided under the folding belt 16 '.
  • the open bottom 19 ' is generated in the manner described above.
  • the embossing device 26' Before the tube piece 13 reaches the second bottom opening device 18 ', it passes through the embossing device 26'.
  • a staggered arrangement of the components is advantageous when producing bags with very small center spacings should be.
  • the embossing means 26, 26 ' may be arranged offset from one another.
  • One possible arrangement would be that the (second) embossing device 26 'is arranged opposite the (first) bottom opening device 18.
  • the piece of tubing with open bottoms 19, 19 ' is present, wherein all components of the opened bottoms are located substantially in the plane of the support 14.
  • a particular aspect of the bottom opening station 8 is the fact that each bottom opening device 18, 18 'is supplied with torque by its own drive. This is illustrated by the motor 22 on the bottom opening device 18. The corresponding motor on the bottom opening device 18 'is not visible in the illustrated view.
  • the motor of a bottom opening device 18, 18 ' primarily supplies the suction bars with a drive torque, so that they can move the material layers away from one another. Also, the spreading elements are powered by this engine with torque.
  • These drives of the floor opening devices 18, 18 ' can each drive one or both rollers 28, 29 of the embossing devices 26, 26' via a transmission.
  • FIG. 3 Now shows the view III - III from the FIG. 2 and thus details of the embossing device 26. In this view, however, was omitted for the sake of clarity on the presentation of hose pieces.
  • the support 14, the folding element 16 and the guide element 17 can be seen.
  • a further guide piece 31 is arranged, which prevents a return of the end of the hose piece in the region of its folded edge.
  • the guide member 25 is mounted on the guide piece 31, which can be done for example by means of screws.
  • the guide member 25 is followed by a pull roller 32, with which the end of the hose piece are pulled substantially in the extension direction of the hose pieces z, so that they touch the working edge 33 of the folding member 16. If this contact was not ensured, the positionally accurate introduction of the folded edges could not be guaranteed.
  • the axis of rotation of the tension roller is inclined. In this case, it comprises a component in the -x direction, in the z direction and also in the y direction.
  • the peripheral surface is parallel to the inclined surface 34 of the folding element 16 (see FIG. 6 ).
  • the piece of tubing 13 runs into the gap between the embossing roller 28 and the counter-roller 29.
  • the counter-roller 29 is driven via a tension element, for example via a toothed belt 35, by a drive with overfeed.
  • the toothed belt 35 transmits its driving force to a gear 41, which is fixedly connected to the roller 29.
  • the embossing roller 28 presses against the peripheral surface of the counter-roller 29 with a defined force.
  • the embossing roller 28 is freely rotatably mounted in one end of a lever arm 36.
  • the lever arm 36 in turn is rotatably mounted in a frame-fixed support 37.
  • the second end of the lever arm 36 is connected to a piston-cylinder unit 38, which applies a force, which is represented by the arrow F.
  • the piston-cylinder unit can be operated with compressed air, whereby the air pressure can be about 3 bar. Due to the mentioned Force, the fold line 27 can be embossed sufficiently well without the material of the hose pieces 13 is damaged.
  • the embossing roller 28 is advantageously also driven, which is based on the FIG. 4 is explained in more detail. If this were not the case, it would first have to be accelerated by a piece of hose 13, but this could result in damage to this piece of hose. However, the drive of the embossing roller 28 takes place via a frictional engagement with the counter-roller 29. Both rollers 28 and 29 have on their outer circumference in each case an O-ring 39 and 40, which roll on each other. The O-rings are arranged so that they do not come into contact with the hose piece 13 (see FIG. 9 ). When a piece of tubing 13 is in the roll nip, as shown in FIG. 9 is shown, the contact between the O-rings can be canceled.
  • FIG. 5 shows the view IV - IV from the FIG. 3 ,
  • the obliquely arranged to the transport direction x guide member 25 can be seen, which overlaps the folding element 16 in the course of the transport direction x.
  • the tension roller 32 and their arrangement in the room are clearly visible.
  • FIGS. 6 to 9 show different, in the FIG. 3 shown views, each now the hose piece 13 is shown. With these figures, the sequence of functions for embossing the fold line 27 is illustrated.
  • the FIG. 6 shows still the horizontally disposed end 15 of the hose piece 13, after it has been threaded under the folding member 16. In dashed line, the edge 42 of the tube piece 13 can be seen, on which the upper wall 43 and the lower wall 44 are connected to each other.
  • the tube piece 13 is transported by means of the transport device 45, which, for example, comprises the tube piece 13 between two transport belts 46 and 47 circulating at transport speed.
  • the transport device 45 which, for example, comprises the tube piece 13 between two transport belts 46 and 47 circulating at transport speed.
  • a further conveyor belt 30 may be provided here. It is the wedge-shaped shape of the folding element 16 can be seen, which includes the working edge 33 at its thinnest point, which determines the position of the later folded edge 27. The location of the fold edge is shown by the broken line 48.
  • the hose piece 13 is already in the region of the guide element 17.
  • FIG. 8 shows the situation in which the guide member 25 has acted on the end 15 of the hose piece 13 and further folded around the working edge 33 of the folding element 16.
  • the angle at which the end is folded is more than 90 degrees, preferably more than 135, in particular more than 150 degrees. Also visible is the guide piece 31, which prevents rolling of the folded edge 27 on the outside, that is, counter to the direction z. Regions of the end 15 can be held in a vertical position by means not shown guide means.
  • FIG. 9 shows the action of the embossing roller 28 and the counter-roller 29 on the wall 44 of the hose piece 13.
  • the embossing roller 28 touches the wall 44, which can be considered here as part of the end 15 of the hose piece 13, while the counter-roller on the wall 44 of the hose piece 13 acts. Between these two effective areas, the folded edge 27 is arranged. The wall 43 is not touched by the rollers 28, 29.
