Definitions

  • the invention relates to a device for adjusting the position of a packaging material web, in particular the web center of the packaging material web, to a reference in a packaging machine according to the preamble of claim 1. Furthermore, the invention relates to a method for adjusting the position of a packaging material web, preferably by means of a device according to the invention and a packaging machine in the form of a tubular bag machine with a device according to the invention.
  • a device is known from DE 10 2011 003 666 A1 known.
  • the device arranged in the feed region of a packaging material web in the region of a tubular bag machine comprises a device which aligns the packaging material web with the forming tube of the tubular bag machine by displacing the packaging web in a direction extending transversely to the transport direction of the packaging material web.
  • a device for adjusting the web center of a packaging material web in which the device has a plurality of deflection or transport rollers around which the packaging material web is guided.
  • rollers are arranged on a pivoting frame which is pivotable about an axis arranged perpendicular to the transport direction of the packaging material web and thereby influences the direction of the conveyed packaging material web.
  • a pivoting frame which is pivotable about an axis arranged perpendicular to the transport direction of the packaging material web and thereby influences the direction of the conveyed packaging material web.
  • the devices known from the prior art have in common that they have only a single device for influencing the position of the packaging material web or its web center. This has the consequence that, ever according to the tolerance layer of the conveyed packaging material web and other circumstances, the packaging material web in the region of the (single) device in its conveying direction must be changed relatively strong, in particular to align the web center of the packaging material web with a reference point of the packaging machine. This means a relatively high mechanical load on the material of the packaging material web, which can be critical especially for relatively thin packaging materials, so that there is a risk of tearing the packaging material web.
  • the invention has the object, a device for adjusting the position of a packaging material web, in particular the web center of the packaging material web to form a reference in a packaging machine according to the preamble of claim 1 such that at relatively low mechanical stress the material of the packaging material web the greatest possible influence on the position or the web center of the packaging material web is made possible to a reference of a packaging machine.
  • critical packaging materials should also be relatively easy to handle on a packaging machine with regard to influencing the web center.
  • the two devices each have a central position and two end positions, and when the control device in approaching the first or second device to an end position the other device such controls that the former device can be moved back towards its middle position , This avoids, in particular, that should one of the devices already be in the region of their end position, a further additional adjustment in the direction of the end position is not possible, or can only be done to a certain extent. It is, so to speak, a self-aligning system.
  • the first device is part of a carrier device in which the packaging material web is stored in the form of a packaging material roll.
  • the design of the first device is therefore relatively simple in terms of device technology, since the already conventionally provided carrier device for storing the packaging material web only has to be designed to be displaceable in a direction transverse to the transport direction of the packaging material web in order to form the first device.
  • such a design of the first device allows relatively large tolerances with regard to the positioning of the packaging material roll on the carrier device, since the desired position of the packaging material web on the carrier device can be set by the first device within a wide range.
  • the second device comprises a pivotable about an axis rotary frame, and that a first distance between the two devices is greater than a second distance between the second device and a forming device of the packaging machine, in the region of the reference is arranged ,
  • a first distance between the two devices is greater than a second distance between the second device and a forming device of the packaging machine, in the region of the reference is arranged ,
  • a slight deviation of the web center is achieved for reference at the critical point of the packaging machine, since between the second device and the reference only a small conveying distance for the Packing material web is provided.
  • a particularly preferred embodiment of the invention provides that a device for measuring web tension acting in the transverse direction of the packaging material web is provided between the two devices, and that a control device controls the two devices as a function of the detected web tension of the packaging material web.
  • a control device controls the two devices as a function of the detected web tension of the packaging material web.
  • a sensor system for detecting the position of the packaging material web is arranged between the second device and the forming device of the packaging machine.
  • the control device of the packaging machine then controls the two devices as a function of the detected position of the packaging material web.
  • the invention also includes a packaging machine in the form of a tubular bag machine with a device according to the invention for adjusting the position, in particular the web center of the packaging material web, to a reference.
  • the invention comprises a method for adjusting the position, in particular the web center of a packaging material web, to a reference in a packaging machine, preferably using a device according to the invention, in which two, in the transport direction of the packaging material spaced separate means for influencing the position of the packaging material web are provided , as well as a control device for Control of the two devices, which controls the two devices to achieve a desired position in response to a detected actual position of the packaging material web.

  • the device 10 comprises a first device 21, which is realized by the carrier device 15.
  • the first device 21 has an adjusting drive, not shown, which makes it possible for the carrier device 15, and thus also for the carrier device 15, to be realized stockpiled packaging material web 1 to move in the direction of the double arrow 22 in a direction perpendicular to the transport direction 23 of the packaging material web 1 direction.
  • the first device 21 comprises at least a first sensor 24, which detects, for example, a web edge 3, 3 'of the packaging material web 1, from which a control device 50 in knowledge of the width of the packaging material web 1 on the exact position of the packaging material web 1 and der Brumitte. 2 , 2 'in the region of the support means 15 closes.
  • the device 10 comprises at a distance A 1 to the first device 21, a second device 26, which has a rotating frame 27 with conveying or deflection rollers, which serves to convey the packaging material web 1. It is essential that the rotating frame 27 about an axis 28 which is perpendicular to the plane of the Fig. 1 runs, is pivotally mounted in the direction of the double arrow 29.
  • the second device 26 is also coupled to the control device 50 in order on the one hand to supply the control device 50 with the position of the second device 26 or its angular position as an input value, and on the other hand by the control device 50 to drive the rotary frame 27 in the axis 28 Position in a desired position.
  • the web center 2 of the packaging material web 1 can be influenced in relation to the reference line 103 of the forming shoulder 102.
  • the second device 26 is located at a distance A 2 to the forming shoulder 102, which in contrast to the representation of Fig. 1 and 2 is significantly less than the distance A 1 between the two devices 21, 26th
  • a sensor system 30 with web edge sensors 31, 32 is provided between the second device 26 and the forming shoulder 102, the signals of which are also supplied to the control device 50 as input values.
  • a deflection roller 33 which feeds the packaging material web 1 to the forming shoulder 102, is also shown by way of example.

  • the transport of the packaging material web 1 from the carrier device 15 to the forming shoulder 102 can take place either continuously or clocked, or in a mixed form, wherein in a partial area between the carrier device 15 and the forming shoulder 102 a buffer area with so-called Dancer rollers is arranged, which allows a balance between a cyclic and a continuous promotion of the packaging material web 1.
  • a device 35 for detecting material properties of the packaging material web 1 is arranged in the region between the two devices 21 and 26.
  • a tension profile of the web tension of the packaging material web 1 can be determined transversely to the transport direction 23 of the packaging material web 1.
  • the device 10 described so far for adjusting the web center 2 of the packaging material web 1 to the reference line 103 of the tubular bag machine 100 can be operated in various operating modes.
  • a first mode of operation is explained, in which the solid state of the web edges 3 and 4 shows the end state of the position of the packaging material web 1 to be reached, in which the web center 2 is aligned with the reference line 103.
  • the dashed representation of the packaging material web 1 ', an initial state with web edges 3', 4 ' is shown, in which between the web center 2 in the final state and the web center 2' in the initial state, a lateral deviation a is present.
  • the position of the packaging material web 1 on the carrier device 15 is first determined by means of the at least one first sensor 24, and then (with knowledge of the width of the packaging material web 1) the adjustably arranged carrier device 15 or the first Device 21 controlled by the control device 50 such that the packaging material web 1 in the illustrated embodiment in the plane of the Fig. 1 is moved from right to left until the actual position of the packaging material web 1 coincides with the desired position, in which the web center 2 is aligned with the reference line 103. Aligning the web center 2, 2 'with the reference line 103 takes place as a function of the web speed of the packaging material web 1 and further, packaging-specific properties.
  • Fig. 3a is shown by the course of the curve X over the time t, the change of the web center 2 'to the referenced web center 2 (curve Y).
  • the course of the control signal for the first device 21 can be recognized by the curve Z.
  • the compensation of the mentioned bow error of the packaging material web 1 is basically compensated for solely by the first device 21, but is favored or accelerated by the second device 26.
  • a second mode of operation is shown, which may occur during production in an already established state of the packaging material web 1 in the already aligned state of the web center 2 to the reference line 103. Since the second device 26 is arranged at a relatively small distance A 2 to the forming shoulder 102 and to the reference line 103 on the forming shoulder 102, it can happen inter alia that the second device 26 is already pivoted so strongly about the axis 28 that this is close to the edge of their work area, which should be represented by the dashed representation of the rotating frame 27 is located. In this case, a further correction of the web center 2 is no longer possible with a deviation a detected by the sensor device 30 in said direction.
  • the second means 26 in order to avoid pauses in production, it is desirable for the second means 26 to be (re) pivoted from the dashed representation back to a middle position, from which deviations a of the web center 2 with respect to the reference line 103 are compensated in both directions by the second means 26 can be.
  • This is done by the first device 21 shifting the carrier device 15 to the right from the position shown by the dashed representation, so that the second device 26 can be swiveled back relative to its angle to the axis 28 in the direction of its middle position.
  • the operation of this second mode of operation is through the Fig. 3b clarified. It is shown that the actual position and the desired position of the web center 2 (curve X) is aligned with the reference line 103 during the entire time.
  • curve Y the control signal for the first device 21 is illustrated, which after a certain time, a return of the second device 26 allows in its center position, which is illustrated by the curve Z (control signal of the second device 26).
  • the device 10 described so far can be modified or modified in many ways, without departing from the objects of the independent claims.
  • the application of the device 10 should not be limited to tubular bag machines 100, but can also be used in other packaging machines. It can also be provided that when the first device 21 approaches one of its lateral end positions in analogy to that in connection with FIG Fig. 2 and 3b explained mode, the second device 26 is driven such that the first device 21 can be moved again in the direction of its central position.
