Definitions

  • the invention relates to a method and a device for producing individual stacks consisting of a zigzag folded material web according to the preamble of claim 1 and claim 5.
  • a separating device in which two conveyor roller pairs are arranged adjacent to one another and are driven in the same direction and at the same speed for advancing the material web.
  • the rear pair of rollers seen in the conveying direction is now stopped, while the other pair of rollers continues to convey the material web.
  • this device is less for applications in which the material web is moved at high speed and often has to be separated, because of the frequent rapid acceleration of said one pair of rollers after each cutting operation suitable.
  • this one pair of rollers must also exert a certain pressure on the material web during conveying in order to be able to clamp it sufficiently strongly when it is stopped. In the case of thin material webs, this is difficult and can lead to damage to the material web.
  • the present invention is based on the object of creating a method and a device which, in addition to a safe separation of the material web along predetermined separation lines, also enables problem-free stack formation with structurally simple means even at high working speeds.
  • the separation point does not change its position during the separation, that is the rear edge of the material web part to be stacked has a precisely defined position, which facilitates the subsequent controlled zigzag folding and placing on the stack.
  • the stack forming process is interrupted until the finished stack has been carried away and the stack forming device is again ready to form a new stack.
  • a part of the continuously occurring material web is preferably temporarily stored in a buffer memory which, after the material web has been separated, can be reduced to its desired height again by briefly increasing the working speed.
  • elements of the feed device for the material web can be used, which simplifies the construction.
  • the material web 2 e.g. made of paper for printers of EDP systems, has perforation lines running along their edges, into which the teeth of a conveyor element 4 driven by the motor 3 engage.
  • the material web 2 has, at regular intervals corresponding to the width of the stack 1 to be formed, perforation lines running transversely along which the folding takes place during stack formation and on which the material web has been pre-folded in an upstream folding device 6.
  • the pre-folding along the transverse perforation lines makes folding easier during the manufacture of the stack 1 and also ensures the exact and easy separation of the material web along such a perforation line.
  • a folding device suitable for use in the device according to the invention is described in more detail in DE-OS 33 44 260.
  • the driven conveyor element 4 removes the material web 2 from the intermediate stack 7, which forms a buffer for the workflow, via a deflection roller 5 pulled and fed a conveyor roller 8 also driven by the drive 3.
  • the material web 2 is deflected vertically downwards by a guide by means of at least one rotating pressure roller 9, past a clamping strip 10, to an oscillating guide 12 which, by its oscillating movement, folds the material web in a known manner on the lifting table 14 in a manner known per se to form the stack 1.
  • the mentioned terminal strip 10, which is fixed, is opposite a movable terminal strip 11, which can be pressed against the fixed terminal strip 10 by a controlled linear actuator 13 in order to be able to hold the material web.
  • the vibration guide 12 has two guide plates 15, 16 which run parallel to one another and between which the material web is guided.
  • semicircular pressing elements 18, 19 are provided in the region of the stacking and folding edges, which are fastened on a shaft 20, 21 rotating synchronously with the oscillating drive of the oscillating guide, not shown. These pressing elements 18, 19 alternately hold the folded edges 22, 23 down on the stack when the material web is folded, so that high working speeds are possible when the material web is folded alternately, ie in a zigzag fashion.
  • the movement control of the folded tray on the table 14 is supported at the beginning of the stack formation by one of the blowing nozzles 24, 25, depending on the direction in which the folding begins.
  • a lifting drive 25 automatically exhausts the lifting table 14.
  • the formed stack 1 is separated from the subsequent material web 2 on the basis of a material web 2 attached, for example printed or perforated marking, which is detected by a signal generator 27 provided on the web guide.
  • the signal then emitted by the signal generator triggers a sequence of preprogrammed operations.
  • the drive 3 for the conveying element 4 and the conveying roller 8 as well as the drive for the vibrating guide 12 and the pressing elements 18, 19 are switched off, but with a delay until the pre-folded perforation line on which the separation is to take place has passed the terminal strip 10 .
  • a thrust drive 28 then moves a conveyor roller 30 driving in the opposite direction into contact with the material web, in the contact area of the conveyor roller 8, so that the material web is moved back.
  • the intended severing point or transverse perforation line has passed through the terminal strip 10 again, this comes into effect through the pressing movement of the opposing terminal strip 11 and holds the material web 2 in place so that it breaks at the intended point 32.
  • 3 shows the moment shortly after the separation with the contact position of the conveyor roller 30 and the terminal strip 11.
  • the lifting table is designed as a conveyor table in that it has endless belts guided over rollers 34, 35.
  • One of the rollers carries a gearwheel 36 which, after the lifting table has been lowered, also to the level of a stationary second conveyor belt 37 a driven second gear 38 engages so that the conveyor belt is transported and the stack is correspondingly transported away from the lifting table 14.
  • a second signal transmitter 40 arranged at the beginning of the second conveyor track signals the transfer of the stack 1 to the second conveyor belt to the drive control of the lifting table 14 in order to bring it back into its upper starting position. After this position has been reached, the conveying of the material web and the device 12, 18, 19, 24, 25 for stack formation are put into operation again until a new marking passes the signal generator 27 and the sequence described is repeated.
  • the upstream folding device 6 does not have to be switched off during the stoppage of the conveyance of the material strip 2, since a stack is also formed there.
  • This intermediate stack 7 acts as a buffer for the continuous refeeding of the material web starting from a supply roll, not shown. Since the folding device 6 forms the stack from the bottom up and is placed on a table 42, the relatively large space above the table 42 provides a large buffer volume. After the conveyor is switched on again, the intermediate stack, which has grown in the meantime, is reduced again by an initially increased working speed of the conveyor and the formation of the stack 1. It goes without saying that suitable control devices are available for this purpose, which also control the height of the intermediate stack.
  • the workflow can also be buffered by another buffer Type, for example, be made according to the representation in Fig. 2.
  • This intermediate storage 44 has two rows 45, 46 of deflecting rollers over which the material web is guided in a meandering manner in the form of successive loops.
  • the upper row 45 of deflecting rollers has fixed axes of rotation, while the deflecting rollers of the lower row 46 are mounted in a frame 48 which is mounted on vertical guides 49, 50, for example under their own weight, depending on the required length of the material web 2 stored in the intermediate store 44, is movable up and down.
  • the state with a large stored length of the material strip 2 is shown by chain lines 51.
  • the material web is stopped at a precisely predetermined location before the severing, so that the perforation line at which the severing is to take place comes to a standstill between the pair of strips 10, 11 and the pair of rollers 8, 9, the pair of strips can be closed immediately to hold the material web in a jammed position, and the brief return transport by means of the then pressed-on conveyor roller immediately causes the separation at this perforation line.
