Definitions
- the invention relates to a machine which processes a material web in cycles, in particular a machine for producing bags or the like from a plastic film web, with a compensating device which receives a predetermined web length, to which the web is continuously fed by a pair of feed rollers and from which a predetermined web length by means of a pair of feed rollers is withdrawn discontinuously.
- a machine of the aforementioned type is known, for example, from British patent application 2 156 320.
- a dancer roller or a dancer arm is used to ensure the material balance between the continuous web feed and the discontinuous web removal by means of a dancer roller or a dancer arm.
- it is not possible to avoid web tension strikes in the material web which is disadvantageous in particular in the case of plastic film webs.
- web tension is too high, web sections of the material web connected to one another, for example via perforation weld seams, are inadmissibly pulled apart, as a result of which the weld seam quality is considerably impaired. This is often noticeable even with relatively small web tensions, since the plastic film web in the area of the perforation weld seams just applied is still at a higher temperature and is therefore more or less plasticized.
- the invention has for its object to provide a cyclically processing a material web machine, in particular a machine for the production of bags or the like from a plastic film web, of the type mentioned, in which a stepwise web length compensation without significant web tension increase is ensured with comparatively simple means and enables a constant, selectable web tension behind the compensation device.
- the guiding of the web in a loose sag in the compensation device prevents the web tension from occurring during the web length compensation between the continuous and the discontinuous movement. Furthermore, the material web can be guided exactly and fed with a preselectable web tension to the pair of take-off rolls for the subsequent, cyclically working processing station.
- Figure 1 shows schematically a side view of part of a machine for producing bags from a plastic film web with the compensating device.
- the machine partially shown in FIG. 1 is used to produce bags from a plastic film web 1.
- the plastic film web 1 is continuously fed to a compensating device 4 by a pair of feed rollers 2, 3.
- the feed roller pair 2, 3 is continuously driven by a motor 23, so that the web 1 is continuously fed to the compensating device 4 arranged downstream.
- the compensation device 4 begins with a suction belt conveyor 5, which consists of individual parallel suction belts 6, which are guided around deflection rollers 7, 8. At least one of the deflecting rollers 7, 8 is driven continuously, preferably at a slightly higher transport speed than the transport speed of the feed rollers 2, 3, so that the web 1 is guided tightly.
- a suction box 9 is arranged between the two runs of the suction belts 6, which can be acted upon by negative pressure. The web 1 resting on the suction belts 6 is sucked in and held by suction openings in the suction belts 6.
- the suction belt conveyor 5 is arranged obliquely downwards in the web running direction, as shown in FIG. 1.
- the end of the compensating device 4 is formed by a second suction belt conveyor 10, which is arranged at a distance from the first suction belt conveyor 5 and runs obliquely upward in the web running direction.
- the suction belt conveyor 10 also contains individual, rotating suction belts 11, which are guided around Umienkwalzen 12, 13. Below the conveying strands of the suction belts 11 is a Suction box 24 is arranged, from which the web 1 is sucked through suction openings in the suction belts 11 so that it rests without slip.
- the suction belt conveyor 10 is driven intermittently by a servo motor 14. The web 1 thus leaves the compensating device 4 discontinuously.
- the web 1 is guided in a loose sag 15 between the two suction belt conveyors 5, 10. Since the feed is continuously carried out and withdrawn discontinuously, the sag 15 changes in time with the withdrawal of the web 1. Two possible sag 15 are shown in FIG.
- the changing sag 15 is detected with a sensor 16, preferably a contactless sensor.
- the feed of the feed rollers 2, 3 is controlled by a control device, not shown.
- the suction belt conveyor 10 is mounted in a rotating frame. This makes it possible to position the edges of the running web 1 exactly.
- a probe 17 is arranged at a distance behind the intermittently driven suction belt conveyor 10, which determines the position of the web edges.
- a sensor 18 is arranged behind the second suction belt conveyor 10 and serves to detect the web tension.
- the web tension between the suction belt conveyor 10 and a pair of take-off rollers 19, 20 arranged at a distance behind it is regulated.
- the extraction roller pair 19, 20 is also driven by a servo motor 21 and feeds the web 1 discontinuously to a subsequent processing device, here a welding device 22, in which perforation weld seams ' are produced in the web 1.
- the plastic film web 1 is withdrawn from the pair of take-off rollers 19, 20 and the suction belt conveyor 10 in cycles from the continuous suction belt conveyor 5.
- the intermittently driven suction belt conveyor 10 is driven synchronously with the cycle of the pair of draw rollers 19, 20.
- the web tension between the suction belt conveyor 10 and the Draw-off roller pair 19, 20 is set to a constant, predetermined value by means of the sensor 18.
- the suction belt conveyor 10 is rotated so that the edges of the web 1 run exactly in the desired area.
- a web section of a predetermined length is drawn off from the pair of draw rollers 19, 20 and the suction belt conveyor 10, while the pair of feed rollers 2, 3 and the first suction belt conveyor 5 continuously convey the web into the compensation device 4.
- the changing sag 15 of the web 1 in the compensating device 4 is detected by the sensor 16 and the speed of the feed rollers 2, 3 is controlled as a function thereof.
- the design of the compensating device 4 according to the invention has the advantage that the discontinuous removal of the plastic film web 1 from the compensating device 4 does not lead to any significant web tension fluctuation, and secondly, a constant, selectable web tension can be set behind the compensating device 4 and in front of the pair of draw-off rollers 19, 20 ,
