Definitions

  • the invention relates to a device for the production and stacking of web sections of paper, cellulose, non-woven fabrics or the like folded once or several times in the transverse direction with the features from the preamble of patent claim 1.
  • Such devices are known per se (see e.g. DE-PS 30 42 519 and DE-PS 32 27 270) and are used primarily for the production of paper or tissue napkins.
  • a disadvantage of the known devices is that, since no interruption in the manufacturing process can be accepted after the completion of a stack, special and generally complex devices must be provided, through which the continuous stack produced by the folding device intervenes, for the production of individual stacks predetermined number of pieces.
  • the object underlying the invention was to design a device of the type mentioned above so that the construction and stacking of the web sections can be carried out without separating an endless stack, with little design effort, which has the advantage that the device can be constructed very compactly can and no complex additional devices for stack separation are necessary.
  • the basic idea of the invention is to assign the same cutting roller to a second folding roller connected downstream of the first folding roller and to control the gripping device of the first folding roller by means of the control device in such a way that the two folding rollers take effect alternately in such a way that the web sections of each form when a first stack is formed removed from the first folding roller and fed to the stack and when the first stack is finished the gripping device of the first folding roller is switched off, so that the web sections then pass through to the second folding roller, are removed from it and are removed to form a second stack.
  • the first stack can be fed to the packaging machine, for example.
  • the gripping device of the first folding roller is switched on again and the next stack is formed again by means of the first folding roller. In this way it is achieved that the folder does not produce an endless stack but individual stacks that can be removed without complex additional devices.
  • the control device can be designed to be purely mechanical, in particular in the case of mechanical gripping devices, that is to say, for example, folding jaws on the folding rollers. These can be controlled, for example, via a curve.
  • counting devices can be arranged on the stacking devices, each of which brings about the switchover after a predetermined number of path sections have been deposited.
  • the gripping devices on the two folding rollers are as Suction slit nozzles formed, which can be acted upon by negative pressure.
  • a mechanical or mechanical-pneumatic control can in principle be used.
  • a longitudinal folding device can be connected upstream in the inventive device of the cross-cutting device, so that web sections are produced which are folded in the longitudinal direction and in the transverse direction, as is customary, for example, in the case of napkins.
  • the longitudinal folding device can be preceded by further devices by means of which the web drawn off from a parent roll is, for example, satinized, printed and embossed.
  • the device according to the invention can be used in a particularly advantageous manner for the production and stacking of web sections folded once in the transverse direction, as explained in more detail below with reference to an exemplary embodiment.
  • the device can be modified using known device parts so that the production and stacking of web sections folded several times in the transverse direction is also possible. This can be done, for example, in such a way that both the first folding roller and the second folding roller are followed by further folding rollers, which pull off a web section that is picked up by the first or second folding roller, is folded once and carried along in the transverse direction, and again pulls it along the detection line fold in the transverse direction. In this way, web sections folded twice or more in the transverse direction can be produced and fed to the stacking devices.
  • a paper or cellulose web 1 is drawn off from a mother roll in a manner not specifically shown, satinized, printed and embossed and fed via a triangular folding sheet 3 to a folding machine designated overall by reference number 2.
  • the web 1 folded in the middle by the triangular folded sheet 3 is first fed through guide rollers 4 and a preferred pair of rollers 5-6 to a cross cutter which consists of a knife roller provided with knives 9 and a cutting roller 8 opposite it with counter knives 10 .
  • This cross cutter cuts the web 1 in the transverse direction so that individual web sections 11 are formed.
  • the jacket of the cutting roller 8 is in itself Known and not specifically shown way provided with suction openings which are subjected to negative pressure, so that the web sections 11 adhere to the cutting roller 8 after cross cutting and are conveyed further in the circumferential direction.
  • a first folding roller 12 is initially arranged, in the lateral surface of which gripping devices designed as suction slot nozzles 13 are arranged.
  • the web sections 11 are each gripped in the middle by the suction slit nozzles 13 during the rotation of the rollers 8 and 12 and are pulled off by the cutting roller 8, wherein they are folded along the detection line, that is to say in the transverse direction of the web.
  • the web sections 16 folded in this way run into a belt section which consists of an upper belt 14 which is guided around the first folding roller 12 and a lower belt 15 opposite the underside of the upper belt 14. Between these belts 14 and 15, which can be designed as round belts, the folded web sections 16 are introduced and removed in the horizontal direction.
  • the upper belt 14 can each consist of several round belts distributed over the web width.
  • the web sections 16 are fed to an ejection device 17 which has a plurality of pivotable fingers, by means of which the web sections 16 clamped in between the belts 14 and 15, through which the lower web 15 leading only at the edge parts is pushed out downwards and one on a lowerable stacking table 32 forming stack 18 are fed.
  • the gripping devices of the first folding roller 12, designed as suction slit nozzles 13, can, as will be explained in more detail below, be switched off in their effect. This shutdown occurs when the stack 18 is a has reached a certain number.
  • a counting device known per se, which is not specifically shown, for example having counting quantity wheels, can be arranged on the stacking device, which causes the gripping devices 13 to be switched off when a certain number of path sections 16 is reached via a control device.
  • the gripping devices 13 of the first folding roller 12 are switched off, the web pieces 11 are no longer pulled off the first folding roller 12, but continue to run on the circumference of the cutting roller 8 into the region of a second folding roller 19, which is seen in the direction of rotation of the cutting roller 8, the first folding roller 12 is connected downstream.
  • the second folding roller 19 also has gripping devices in its outer surface which are designed as suction slot nozzles 20. Through the suction slit nozzles 20, the web sections 11 are gripped in the middle, similar to the first folding roller 12, pulled off the cutting roller 8 and thereby folded along the detection line, that is to say in the transverse direction to the web.
  • the second folding roller 19 is followed by a belt section with an upper belt 21 consisting of a plurality of round belts distributed over the web width and a lower belt 22 also consisting of round belts engaging on the edge parts of the web sections 24.
  • This belt section is analogous to that of the belts 14 and 15 existing belt section constructed and the web sections 24 folded in the transverse direction are inserted between the belts 21 and 22, conveyed further in the horizontal direction and fed to a stack 25 by means of an ejection device 23, which is constructed analogously to the ejection device 17.
  • the gripping devices 13 of the first folding roller 12 are switched on again.
  • the stack 18 has been removed by means of a transport device described below.
  • the web sections 11 are again taken over by the first folding roller 12 and a new stack 18 is formed in the manner described above.
  • a switch is again made to the second folding roller 19.
  • the device enables the production of individual packages in any desired number of pieces.
  • the first folding roller 12 is shown in a position in which the gripping device 13 is switched on and a web section 11 in its center M is gripped by the gripping device 13 designed as a suction slot nozzle.
  • a vacuum chamber 26 is arranged inside the jacket of the first folding roller 12, into which the suction slot nozzles 13 arranged in the jacket open.
  • the vacuum chamber is connected to a suction device (not shown) via connecting channels 27 and a longitudinal channel 28 arranged in the roller axis 29 which is fixed relative to the jacket.
  • Between the inner surface of the jacket of the first suction roller 12 and the vacuum space 26 is one together with the Arranged roller axis through an angle predetermined by the directions A and B, not rotating with the jacket aperture 31.
  • This diaphragm which extends in the circumferential direction, has a cutout 30 which extends over an angular range of approximately 90 °. Only when the sow g slit nozzles 13 are located in the area of the section 30, they are applied from the negative pressure chamber 26 with out vacuum.
  • the diaphragm 31 is firmly connected to the roller axis 29 and both are by means of a pivot element 38 from the position shown in FIG. 3, in which the pivot element 38 points in direction A; 4, in which the pivoting element 38 points in the direction B. In the position shown in FIG.
  • the cutout 30 of the diaphragm 31 extends from a point directly in front of the suction slot nozzle 13, which just covers the center M of the web section 11, to a point offset by approximately 90 ° in the direction of rotation.
  • the suction slot nozzle 13 is acted upon by vacuum from the vacuum chamber 26 at the point at which it lies directly opposite the web section 11, so that the web section 11 is gripped, pulled off and folded in the manner indicated above. It is held by the suction slot nozzle 13 while the folding roller 12 continues to rotate until the suction slot nozzle 13 is covered by the lower edge of the diaphragm 31 in FIG. 3 after passing through an angle of somewhat less than 90 °. At this moment, there is no longer any vacuum at the suction slot nozzle 13 and the folded web section 11 is released after it has already entered between the belts 14 and 15, which are not shown in FIG. 3.
  • the pivoting element 38 is brought into the position shown in FIG. 4, in which the cutout 30 of the diaphragm 31 is rotated to such an extent that the suction slit nozzle 13 is only subjected to negative pressure from the negative pressure space 26 when it is above the direct contact point has run out with the cutting roller 8 on the straight CD.
  • the distance of the suction slit nozzle 13 from the web section 11 resting on the cutting roller 8 is then already so great that suction of the web section 11 is no longer possible. Rather, the web section 11 continues to run until it comes into the area of the second folding roller 19, the gripping device 20 of which is switched on, and is only pulled off the cutting roller 8 there.
  • the gripping devices 20 of the second folding roller 19 are likewise designed as suction slot nozzles, but need not be able to be switched off. This means that an aperture can be arranged inside, which is designed analogously to the aperture 31 with a cutout 30 which extends over an angular range of approximately 230 °. However, this aperture does not have to be pivotable.
  • the swivel element 38 can be connected to a mechanical, pneumatic or electronic control device, which is not specifically shown.
  • the pivoting element 38 can be actuated by means of a pneumatic cylinder which is pressurized shortly before the switching time. The exact timing of the control, which must be adhered to very precisely, can then be determined in that a locking device controlled by a control cam releases the pivoting of the pivoting element 38 by the pneumatic cylinder.
  • the manner in which the stacks formed are discharged is described below with reference to FIG. 5.
  • the explanation relates to the stack 18 formed by the ejection device 17 on the stacking table 32.
  • An analog device is also used to remove the stack 25.
  • the stacks 18 and 25 are deposited on the surface 33 of a common filing table 34 after their completion.
  • the surface 33 of the storage table 34 is at the level of the lower end position of the stacking table 32.
  • a conveyor device constructed as a double chain system 35 with vertically standing drivers 36 is arranged, by means of which the stack 18 is pushed off the stacking table 32 and conveyed onto a packaging machine chain , on which the stacks are then fed by carriers 37 of the packaging machine, not shown in detail.
  • FIG. 2 A total of three units 2.1, 2.2 and 2.3 are arranged in a common machine stand 39, each of which has a cross cutter and a folding machine of the type described with reference to FIG. 1. The same reference numerals are therefore used in FIG. 2, which are distinguished by the indices ".1", “.2” and ".3".
  • the three units 2.1, 2.2 and 2.3 work on the same storage table 34 ', from which the stacks are fed to a common packing machine.
