Definitions

  • the invention relates to a device for forming gaps between web sections of a web of paper or a similar material that is folded in a zigzag shape, divided by separating cuts and moved along a conveying path.
  • DE-OS 37 38 139 discloses a generic zigzag folding principle with the formation of folding loops in a shingled formation from previously separated material webs of defined length, the folding loops then starting with the stack formation in the gap formation phase between successive material webs Pass over folds along the lines of weakness and finally form discrete stacks of zigzag folded web sections.
  • the invention has for its object to perfect the process of gap formation so that it fits smoothly into the workflow even at high throughput speed of the folding loops.
  • the conveyor line is provided with a periodically actuated acceleration means which detects the web section to be separated from the web and leads in the conveying direction up to the region of the separating cut to the trailing web.
  • the acceleration means is formed by conveyor belts which are integrated in the conveyor section and run parallel to one another and are arranged in the region of a separating cut with rows which are offset with respect to one another in terms of their start and end in an initial position are provided by suction openings, the conveyor belt having the row of suction openings leading in the conveying direction, together with the downstream units of the machine, being switchable from a normal to a faster conveying speed by means of an acceleration drive and vice versa.
  • the arrangement is such that the rows of the suction openings of the middle conveyor belt and an outer conveyor belt are offset in the conveying direction to the rows of the suction openings of the other outer conveyor belt, wherein according to additional configurations the one outer conveyor belt is provided with control means permitting permanent suction air, on the other hand, the other outer conveyor belt and the middle conveyor belt are periodically provided with control means which let the suction air through or block the suction air.
  • the advantage achieved by the invention is that the gap formation system integrated into the normal movement of the conveyor line using only control technology means a practically mass-free acceleration and deceleration of the conveyor belts which take over both the normal transport and the pulling of the gaps.
  • the gap formation system thus optimally adapts to any web throughput speed or leaves room for a further increase in the web speed to be expected in the future.
  • FIGS. 1 only part of a multi-use (ie several parallel conveyor tracks) operated overall system for the production of zigzag folded webs of paper or the like is shown, of which an endless web 1 obtained by longitudinal separation from a multi-wide paper web can be seen.
  • the paper web 1 consisting of adjacent web sections, delimited by transverse weakening lines, in particular perforations, is placed in successive folding loops 2 according to FIGS.
  • the folding loops are formed here by rolling over each web section with the web section adjoining this, as a result of different speeds of belts 3 and 4, so that each folding loop 2 consists of two web sections.
  • material webs 7 of a defined length separated from the endless web 1 before the folding loop is formed by means of a circumferential cross cutter 6.
  • Such material webs 7 obtained by separation along a section line 8 symbolized in FIGS. 2a, 2b now run immediately after the formation of the folding loops, immediately one after the other, in a conveyor line 9, the structure and different working positions of which are shown in FIGS. 2 to 5. It is now important to form a distance or a gap L between the leading material web 7a and the following material web 7b during the conveying in the direction of arrow 11, as can be seen in FIGS. 3a, 3b, and then the To enable the formation and removal of discrete stacks of zigzag folded web sections.
  • the conveyor line 9 is provided with three parallel conveyor belts 11, 12, 13, of which the outer conveyor belts 11, 13 are driven at a constant basic speed and by which the central conveyor belt 12, deviating from the basic speed, is designed as an accelerating means which is actuated periodically by means of an acceleration drive in the form of a motor 14 and a differential 16.
  • suction openings 17 are included in all three conveyor belts 11, 12, 13. The suction openings 17 each form a first row 18 in groups of three in the outer conveyor belt 11, a second row 19 in the middle conveyor belt 12 and a third one in the outer conveyor belt 13 Row 21 of suction openings.
  • the rows of suction openings 19, 21 of the central conveyor belt 12 and of the outer conveyor belt 13 are arranged offset in a starting position to the row of suction openings 18 of the other outer conveyor belt 11.
  • the suction openings 17 communicate with corresponding suction chambers 22 on the underside, which are controlled by valves 23, 24, 26 for the conveyor belts 11, 12, 13.
  • the middle conveyor belt 12 can also be returned to an initial position alternately with the acceleration drive 14, 16 by means of a deceleration drive formed by a motor 27 and a differential 28.
  • the three suction chambers 22 of the conveyor belts 11, 12, 13 in the open switching state of the valves 23, 24, 26 are connected to a vacuum source 37, for example the suction side of a blower.
  • the valves 24 and 26 are assigned switching elements in the form of storage elements 38 and 39, respectively.
  • Accelerator motor 14 and deceleration motor 27 are also assigned memory elements 41 and 42, respectively.
  • a main drive motor 43 of the machine drives all conveyor elements, such as.
  • Rotary pulse generators 44, 46, 47 for example of the type IG 17 ABO OO 10-E4-M3-OP from SICO, FRG and timing relays 48, 49, 51, are used to activate the valves and drives mentioned or to set and delete the associated memory elements. 52, which are connected upstream of the respective storage elements.
  • the mode of operation of the device according to FIGS. 2-6 is as follows:
  • the control cycle for the conveyor belts 11, 12, 13 begins according to FIGS. 2, 2b at the moment when the cutting line 8 of the separating cut produced by the cross cutter 6 according to FIG. 1 changes the position between the suction opening rows 18 and 19, 21 of the conveyor belts 11 and 12, 13 reached according to FIG.
  • This point in time is determined by a pulse shift of the rotary pulse generator 44 from the cut cut of the cross cutter to the aforementioned position of the cut line 8 in accordance with the respectively desired, separated web length or number of web loops.
  • the control 39 of the memory 39 set in a previous control cycle is erased by a control pulse of the rotary pulse generator 44 and the valve 26 is closed by a drop in its output signal, and thus the rows 21 of the suction openings of the conveyor belt 13 are ineffective.
  • the valves 23, 24 through the previous control cycle opened and the rows 18 and 19 of the suction openings of the conveyor belts 11, 12 are acted upon by suction air.
  • the memory 41 is also set via the timing relay 51, the output signal of which sets the acceleration motor 14 into operation after the valve closes.
  • the trailing material web 7b which is gripped by the rearwardly displaced, activated row 18 of suction openings of the conveyor belt 11, is advanced by the main drive motor 43 at the basic or normal speed of the outer conveyor belts 11, 13, while the leading material web 7a is held is activated by the activated row 19 of the suction openings of the middle conveyor belt 12, which is driven faster by the acceleration drive 14, 16 relative to the conveyor belts 11, 13, to the distance of a defined gap L according to FIGS. 3a, 3b from the following material web 7b.
  • the subsequent units in the form of the stacking station 29 or the conveyor belts 31 leading to this are driven at this higher speed.
  • a number of pulses corresponding to the desired gap L is counted or advanced by the rotary pulse generator 46 assigned to the acceleration motor 14.
  • the valve 24 of the middle conveyor belt 12 is closed by signaling the rotary pulse generator 46 to the delete input of the memory 38 and by simultaneous signaling to the delete input of the memory 41, the acceleration drive 14, 16 of the conveyor belt 12 stopped and also the subsequent units 31, 29 reset to the normal speed. According to the position shown in FIGS.
