Definitions

  • the invention relates to a method for connecting material webs of packaging material, namely a web start of a web of material wound as a bobbin - new bobbin - new web - with a web end of a web of material - runoff web running off from another bobbin - drain bobbin -, the web start of the new web by Puller on the circumference of the new bobbin is grasped, pulled off and connected in the region of a connecting unit to the end of the runway by gluing or the like. Furthermore, the invention relates to a device for performing the method.
  • the invention is concerned with the handling of wrapped, web-shaped packaging material (bobbins) made of paper, tinfoil or polyfoils in connection with packaging machines. It is a matter of performing an automatic change of the bobbins even with powerful packaging machines, that is, connecting a new, "full” bobbin (new bobbin) to the running material web (run-off path).
  • the invention has for its object to ensure a reliable connection of the new track of a new bobbin to the runway with the help of simple organs.
  • the method according to the invention is characterized in that the new web is pulled by the pull-off member while pulling off a web section in a conveying cycle up to or beyond the area of the connecting unit and held until it connects to the run-off web.
  • the puller designed in the sense of the invention is preferably a swivel arm which can be moved back and forth in the vertical plane and which has a holder at the free end, in particular a take-up roller having suction bores. This captures an end piece of the new web and fixes it by winding and suction air. It is important that the puller grips the new web on the new web, pulls it off and transports it to the position for connection to the runway.
  • the pulling device or the holder for the new web is accordingly conveyed with the new web through the connecting unit and held in a position which is favorable for the connecting process.
  • the new web and the runway are pressed against one another, severed together and then connected to one another to form a continuous web.
  • the pulling device then returns to the starting position.
  • FIG. 1 an embodiment of a web connecting device is shown, which is used in connection with a packaging machine.
  • this unit can be used in cigarette packaging machines.
  • the material webs to be handled consist of packaging material, for example of paper, plastic or tinfoil.
  • the packaging machine With continuous conveyance, the packaging machine is supplied with a running material web, that is to say a running web 10. This is subtracted from a bobbin, namely from a drain bobbin 11. A second, "full" bobbin, ie a new bobbin 12, is kept ready. After the drain bobbin 11 has been used up, it is a matter of connecting a new track 13 to be pulled off the new bobbin 12 to the drain track 10.
  • the two bobbins namely drain bobbins 11 and new bobbins 12, are rotatably mounted on a two-armed rocker 14 and are preferably driven by a motor. Free ends of the rocker 14 are designed as a fork 15. This facilitates the feeding of new, full bobbins to the web connecting device.
  • the rocker 14 is rotated into an upright position to accommodate a new bobbin.
  • a support pin 16, 17 is pivotally mounted for receiving a bobbin.
  • the support pins 16, 17 In a horizontally directed position, that is to say transversely to the rocker 14, the support pins 16, 17 are in the working position.
  • the material webs can be pulled off the respective bobbin.
  • the support pin 16 or 17 of the fork 15 which is directed upwards is pivoted into an upright position. A new bobbin can now be placed on the support pins 16, 17 from above.
  • Two sub-assemblies belong to the rail connection device.
  • a connection unit 18 is provided, which establishes the connection between the runway 10 and the new path 13.
  • the drain bobbin 11 is monitored by suitable, known monitoring bodies with regard to the remaining size.
  • the connection of the new runway 13 to the runway 10 is prepared in good time.
  • the rocker 14 is in an obliquely directed position, in which the drain bobbin 11 is at the bottom and the new bobbin 12 is at the top. It is now a matter of detecting a front end 19 of the new web 13 and feeding it to the connecting unit 18.
  • a puller 20 is provided for this. This is designed here as a swivel arm 21, which is in the vertical plane between a receiving position (shown in dashed lines) on the new bobbin 12 and a transfer position in the area of the connecting unit 18 can be moved back and forth.
  • a receiving head for the front end 19, in the present exemplary embodiment a rotatable receiving roller 22.
  • This is provided with a plurality of radially directed suction bores 23 which are connected to a vacuum source.
  • the new web 13 is detachable, namely by means of a peel-off adhesive, connected to an underlying winding layer 24 of the new bobbin 12.
  • the attachment of an area of the new track 13 facing the front end 19 is selected such that an exposed, ie non-attached end piece 25 of, for example, several centimeters in length is formed.
  • the free end piece 25 can also be formed by an adhesive strip 26 with which the front end 19 of the new web 13 is fastened to the winding layer 24.
  • the adhesive strip 26 has an adhesive area 27 which fixes the front end 19 and the adhesive-free end piece 25.
  • the new web 13 is connected to the winding layer 24 by adhesive 28. This is attached at a distance from the front end 19 so that the free end piece 25 is formed.
  • the puller 20 grasps the free end piece 25 and then pulls a web section 29 from the new bobbin 12 while releasing the adhesive connection.
  • the procedure for receiving the new web 13 is similar if it is fixed with an adhesive strip 26 (FIG. 2).
  • the pick-up roller 22 is provided with a plurality of suction bores 23 for securely gripping the end piece 25, particularly in the central region, namely with two closely spaced rings of suction bores 23, in particular in the region of the adhesive strip 26.
  • the head that is to say the take-up roller 22 is moved until it rests on the peripheral surface of the new bobbin 12.
  • This is now driven in rotation, specifically in the unwinding direction, that is to say in the direction of the withdrawal movement of the new web 13 in accordance with the direction arrow 30.
  • the take-up roller 22 is driven in a correspondingly rotating manner in the opposite direction. The rotary movements are carried out until the free end piece 25 abuts the circumference of the take-up roller 22 and is gripped by the suction bores 23 (FIG. 5). A pulling force is now exerted on the end piece 25 and the adhesive connection until a sufficient track piece is gripped by the take-up roll 22.
  • the puller or its swivel arm 21 is now moved in the direction of the connecting unit 18 and beyond it.
  • the pulling-off movement of the new web 13 or of the web section 29 goes so far that it lies against the underside of a pressure plate 31 of the connecting unit 18 (position according to FIG. 8).
  • the new track 13 or the track section 29 provided for connection to the run-off track 10 is accordingly moved by the pulling member 20 in one movement cycle from the pick-up position on the new reel 12 to the end position in the area of the connecting unit 18.
  • the web section 29 is held in the correct position by the pulling member 20.
  • the new bobbin 12 can also be driven by a motor in the direction of rotation.
  • the plane of movement of the swivel arm 21 lies outside of or next to the connecting unit 18.
  • the connecting unit 18 has the task of forming a path end 32 of the run-off path 10 and a path start 33 of the new path 13, to position it in an exact relative position, namely immediately adjacent to one another, and then to connect it to one another.
  • runway 10 and new runway 12 are placed next to one another in the region of the connecting unit and severed together.
  • web end 32 and web start 33 lie directly next to one another.
  • Runway 10 and new runway 13 can thus be connected to one another without gaps.
  • the special design of the connecting unit and the feeding of the new web 13 to it in one movement cycle of the pulling device 20 enables the new web 13 or the web section 29 to be transferred to the connecting unit 18 in an exact position. In this way, the exact position can be achieved of the separating cut can be determined by the webs. This is important if the material webs have a print, for example that of a blank for packaging.
  • Both lanes, that is to say runway 10 and new lane 13 can be controlled by suitable sensors 34, 35, which are assigned to each lane, with the aid of print marks. The printed marks sensed by the sensors 34, 35 generate a control signal on drive elements for the webs in such a way that they are stopped in the exact position in the area of the connecting unit 18.
  • the connecting unit 18 consists of the pressure plate 31 and a counter-pressure element, namely a pressure piece 36 on the free side of the runway 10, that is, below.
  • the support piece 39 can be moved up and down with the pressure piece 36 and the deflection rollers 37, 38.
  • a lower position corresponds to the working position during the removal of the runway 10 (dashed line in FIG. 1). In this position, the web section 29 of the new web 13 can be moved into the region of the connecting unit 18 in the manner described.
  • the run-off track 10 on the downward side or on the side facing the packaging machine is pressed by the pressure piece 36 against the new track 13 and with it onto the pressure plate 31.
  • the runway 10 is now stopped.
  • the processing machine (packaging machine) can continue to run.
  • the required web material is drawn from a web store 40, which is designed here as a multiple rocker.
  • the processing machine is operated with reduced power during this phase (crawl gear).
  • a cutting knife 41 is moved across the webs.
  • the separating knife 41 runs in a groove 42 of the pressure plate 31.
  • the separating knife 41 is attached here to a carriage 43 which can be moved on transverse guide rods 44.
  • the remaining web parts resulting from the separating cut are held in the predetermined position within the connecting unit 18.
  • the divided web section 29 of the new web 13 is held on the pressure plate 31 by suction air, which is generated via bores 46 on the downward contact surface of the pressure plate 31.
  • a section facing the take-up roll 22 is held together with the remaining runway 10 by the pressure piece 36.
  • a strip encoder 48 which can be moved up and down is attached to the support piece 39.
  • it is a swiveling arm with a transverse arm and a holding surface 49 for the connecting strip.
  • the strip dispenser 48 In the lower position of the pressure piece 36, the strip dispenser 48 is loaded with a new connecting strip.
