Definitions

  • the invention relates to a device for producing sacks of hose pieces according to the preamble of claim 1.
  • Such devices are known and available on the market for a long time.
  • 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 superposed material webs, which can each consist of several layers.
  • the tube is cyclically advanced in its longitudinal direction in each case by a length of hose piece.
  • 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.
  • each tube piece produced in this way is taken over by at least one transport device in order to transport it into the individual processing stations.
  • transverse direction is meant that the pieces of hose now be transported transversely to its longitudinal extent, to obtain in the further steps for the production of bags unhindered access to both ends of the hose pieces.
  • a previously separated piece of hose along its longitudinal axis by means of a suitable means of transport are guided 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 fold edge created.
  • a valve is placed on the open bottom on a bottom opening in the valve dispensing station. Through this valve, the bag is later filled with a suitable filling member.
  • a suction spreader system is used to place an open cross floor.
  • This comprises at least one revolving tool, in particular a pair of sickles, for spreading open the ends of the hose pieces which were previously opened over the suckers and for aligning the corner folds which thereby form.
  • the tool cuts out both the front and the rear pocket of the soil.
  • the operation of this suction spreader and in particular of the rotating tool, in particular sickle pair results from the DE 1 753 634 A ,
  • a piece of hose 1 is formed of a fabric of stretched plastic tape, which extends to the solid boundary lines 2. Beyond the boundary lines 2, the polymer extends in an edge region 3. The position of the Hose section within the device is determined by the outer edge of the polymer.
  • FIG. 1a the ideal case is shown in which the fabric corresponds exactly to the desired width and a uniform supernatant 3 is formed on both sides by the coating polymer.
  • the manufactured tube sections will often deviate from this ideal case. Different deviations are also in the FIG. 1 shown. That's how it shows FIG. 1b the condition in which the tissue is too wide.
  • the dashed line would be the ideal line in FIG. 1 is shown.
  • the solid line 2 shows the actual borderline of the ribbon fabric, which deviates from the ideal width.
  • a sucker spreader system is used to open the hose ends and form an open bottom square.
  • the setting of the spreading station depends on the hose width, more precisely on the fabric hose width without a laminate overhang, ie without a protrusion of the coating polymer. If there are fluctuations in the fabric hose width, as shown above with reference to the real pieces of hose originating from the production, the optimized setting is lost, whereby the quality of the opened bottom square suffers and leads to problems in the further processing. Also moving the fabric hose as in Figure 1d shown here can lead to corresponding problems.
  • this object is achieved by a device for producing sacks of hose pieces having the features of claim 1.
  • At least one sensor is arranged in the transport path, by means of which the exact position of at least one of the edges of the tube pieces formed by the tissue can be detected. Furthermore, means are provided which control the movement sequences in the at least one subsequent bottom opening station according to the detected position of the edge of the tube sections influence.
  • exactly the orientation of the edge region formed by the plastic ribbon fabric can be determined by means of a sensor. This position can be transmitted via suitable means of the subsequent floor opening station, there to tune the movements for opening the floor on the exact alignment of the edge formed by the plastic tape fabric.
  • the senor detects at least the position of the rear edge of the plastic ribbon fabric, wherein the movement of the rotating tools for spreading the previously opened ends of the hose pieces is adapted to the position of this edge.
  • the senor further recognizes the position of the front edge of the plastic ribbon fabric, wherein the movement of the rotating tools for spreading the previously opened ends of the hose pieces is adapted to the position of this edge.
  • the rotating tools for spreading the previously opened ends of the hose pieces are moved so that they first come into engagement with the front edge of the hose piece, this spreading, then in contact with the hose piece on this slide and then briefly come out of engagement with the hose piece before or in the area of the rear edge.
  • the tools are then moved so that they then slide into contact with the hose piece on this, at a speed which is below the transport speed of the hose pieces on the conveyor belt.
  • the rotating tools for spreading open the previously opened ends of the hose pieces with a predetermined speed profile emotional.
  • the speed profile can correspond to a uniform movement.
  • the velocity profile will provide different velocities, especially for the phases in which the tools are out of contact or in contact with a piece of tubing.
  • the movement profile of the rotating tools for spreading open the previously opened ends of the tube pieces to the position of the at least one edge of the plastic ribbon fabric is particularly preferably adapted.
  • the movement of the tools may be slowed down before they come into contact with the hose piece.
  • the front edge of the plastic ribbon fabric is in front of the normal position, the movement of the tools before they come into contact with the hose piece can be accelerated.
  • the at least one sensor above and / or below the transport path in the transport direction, which extends transversely to the extension direction of the hose piece, may be arranged.
  • Two sensors are particularly advantageously arranged next to one another such that they can detect a side edge of the tubular piece formed by the tissue. As a result, the exact alignment of the respective side edge formed by the ribbon fabric is detectable. With a corresponding passage of the hose can thus be accurately detected and the width of the hose.
  • the at least one sensor above and / or below the transport path in the transport direction, which runs along the direction of extension of the hose piece may be arranged.
  • two sensors may advantageously be arranged opposite one another in relation to the conveyed hose piece in such a way that they can detect the opposite side edges of the hose piece formed by the fabric.
  • the means for influencing the movements in the bottom opening station of actuators, via the motor, the movements of the tools necessary for the formation of the soil, in particular the rotating sickle pair are adapted to the exact detected position of the fabric edge of the tube section.
  • the movement generated by the actuators with the movement of another drive, which generates a drive movement of the necessary tools for forming the soil, in particular the rotating tools are superimposed, the further drive advantageously generates a nonuniform drive movement via a mechanical non-uniformity gear.
  • the means for influencing the movement sequences in the bottom opening station may consist of control commands which serve in a system control for the control of servomotors used as individual drives of the tools necessary for forming the bottom, in particular of the revolving sickle pair.
  • the invention makes use of the fact that, on the one hand, the plastic ribbon fabric is opaque, while the coating consisting of the polymer is translucent.
  • optical sensors are therefore used to detect the tissue edges. These advantageously have a light source and a light receiver, between which the pieces of tubing are passed, so as to accurately detect the side edges formed by the opaque plastic ribbon fabric.
  • a light source for the optical sensors are particularly suitable lasers with which the translucent polymer layer can be illuminated.
  • one or more capacitive and / or mechanical sensors may be used to detect the at least one edge of the plastic ribbon fabric.
  • the device according to the invention may have the components described in the introduction with respect to the prior art and / or be constructed and / or operated as described above with respect to the prior art.
  • means for adapting the length of the bottom cover sheets to the detected width of the fabric of the tube sections may be present.
  • the exact position of at least one of the edges of the hose pieces formed by the fabric is detected and the movement sequences for laying the open cross base are adapted to the detected position of the commercial edge.
  • the method is preferably carried out as already described in more detail above with regard to the device according to the invention.
  • a device may be used to carry out the method, as has been described above.
  • FIG. 1 schematically shows individual steps for processing a fabric tube 1 into sacks, as they take place in the sack manufacturing device 10 according to the invention.
  • the fabric tube 12 is fed to the sack manufacturing device 10. This is done in an advantageous manner by unwinding a fabric 14 forming a fabric tube in an unwinding 16. Subsequently, the tube 12 undergoes the so-called opening in the opening station 18. 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 tube, 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 hose are put back on top of each other.
  • the fabric tube is then fed to the cross-cutting device 20, which separates the fabric tube into individual tube pieces. Subsequently, a change of the original transport direction z, in which the hose or the hose pieces were transported in the direction of their longitudinal axes, in the new transport direction x, so that the hose pieces are now no longer transported in the direction of z tube longitudinal axis, but transversely thereto, so the ends of the pieces of tubing are laterally accessible for the purpose of forming the bottoms.
  • both ends of each tube piece are opened and the so-called bottom squares are laid.
  • a valve is placed on one of the two open ends and fastened.
  • the open floors are now closed in the bottom closing station 26, wherein two tabs are stacked. These can then be connected to each other permanently, for example by welding.
  • the completion of the actual sack manufacturing process forms the application of a bottom cover sheet on the floors in the cover sheet station 28.
  • the cover sheets can also be welded.
  • the finished bags are then placed on the one stack of sacks 30 and transported away from there on unspecified manner.
  • two optical sensors 32 and 34 are provided, via which the exact position of the edges of the plastic ribbon fabric (compare lines 2 in FIGS FIGS. 1 ) is determined.
  • the corresponding sensors 32 and 34 are arranged in the device 10 in the region of the edges of the tube pieces 1, while they are still transported in the direction z of their tube longitudinal axis.
  • the two respectively in the edge region of these pieces of hose opposite sensors so the exact positioning of the edges and thus the exact width of the hose pieces during transport of the hose pieces in the transport direction z are detected.
  • These data are forwarded to the actuators at the bottom opening station 22 in a manner not shown here.
  • the speed of the tool can be reduced or increased in dependence on the position of the rear edge of the fabric of a piece of hose determined by the sensor, while the tool is in contact with the piece of hose in order to adapt the tool movement to the position of the edge.
  • the speed of the tool can be reduced or increased depending on the determined by the sensor position of the front edge of the fabric of a piece of tubing before the tool comes into contact with the hose piece to adjust the tool movement to the position of the edge ,
  • FIG. 3 An alternative embodiment of the invention results from the FIG. 3 , There is a slightly modified device 10 is shown, but is constructed substantially similar. Here, the individual stations 40 are pulled apart to form the cross bottoms.
  • the piece of tubing 1 to be processed is conveyed in a manner not shown here, first in the direction of the arrow z, that is to say in the direction of the tube longitudinal axis.
  • the transport direction z in which the hose or the hose piece was conveyed, was changed to the new transport direction x.
  • two sensors 36 and 38 arranged next to one another are located above the transport plane of the hose piece 1 transported in the direction x.
