Definitions

  • the invention concerns a device for separating a web into parts and for stacking said parts, possibly after folding, said device comprising a workstation with a supporting structure and with a web-transporting device, a separating device and a folding device, mounted on the supporting structure and further comprising a collecting device for collecting the web parts into stacks, said collecting device being situated under the workstation and comprising a portion which is at least horizontally movable with regard to the workstation and means for moving this portion.
  • the folding device used hereby contains known means for laying down web parts in a zigzag manner on a platform or on web parts already present on this platform and elements for flattening the folds. Also, these flattening elements must be situated practically at the height of the platform or the stack already placed upon it. Since the stack becomes ever higher as more of a web part or more web parts are put on the platform, it should be possible to move the workstation and the platform with regard to one another.
  • a device of this kind is known from EP-A-0 187 344.
  • the workstation is stationary while the platform is movable up and down. Before a stack is formed on the platform, it is raised against the workstation. As the stack becomes higher, the platform is lowered. When the stack is sufficiently high, the platform is lowered to the height of a horizontally movable portion of the collecting device. By means of a mechanism, the stack is finally pushed from the platform on two said movable portion.
  • the distance between the platform and the workstation is relatively large and larger than the height of the highest stack which should be collected by the collecting device. If however only a small stack is required, after formation of the stack, the platform has still be lowered over a relatively large distance to the level of the horizontally movable portion, which implies a loss of time.
  • the mechanism to push the stack from the platform makes the construction of the device more complicated and also this pushing off requires extra time.
  • the separating device is a device for tearing apart the web.
  • This tearing device comprises a mechanism for retaining the web and drive means situated upstreams for moving the web in the backward direction. To permit tearing apart, the web has to be pre-perforated in the crosswise direction.
  • this known device can only treat a pre-folded web provided with perforations along the folding lines. As for each tearing the web movement has to be reversed, the formation of stacks of separate forms from a web is very time-consuming, as the web has to be teared on each folding line.
  • the invention aims to provide a remedy to the above- mentioned disadvantages and to provide a device for separating a web into parts and for stacking said parts, possibly after folding, according to the invention which has a relatively simple construction but which is fast-working, also when stacks of separate forms are desired, and which does not require a pre-folding or pre-perforating in the crosswise direction of the web.
  • the separating device is a cross-cutting device and the workstation is movably up and down above the horizontally movable portion of the collecting device, such that a stack is formed directly on this portion and the device comprises means for moving the workstation up and down as a function of the height of the stack formed on the movable portion.
  • a device for folding and stacking a web wherein the folding device alone is movable up and down in function of the height of a stack formed on a stationary platform is known as such from US-A-4 504 051.
  • This device does not comprise any means for separating the web and it can only be used to form stacks from a prefolded web. Difficulties appear when the memory of the folds is lost.
  • the folding device does only comprise guiding means but no flattening elements.
  • DE-A-3 346 841 discloses a device for refolding a prefolded web and stacking it on a stationary support. It does not comprise any means for separating the web.
  • the folding device is comprised of an upper part and a lower part which are movable with respect to each other in the vertical direction. When a stack is formed on the stationary platform, the lower part is moved upwards with respect to the upper part as a function of the increasing height of the stack.
  • the folding device can be put in and out operation.
  • the device can also easily stack loose sheets, which of course must not be folded.
  • the device then also contains a rotating element to collect a sheet from the folding device put out of operation and to lay down on the collecting device or the stack which has already been formed thereon, said rotating element being mounted on the supporting structure in a movable manner and being situated in one position at or under the lower end of the folding device put out of operation.
  • the folding device comprises a guide for the web parts which is suspended to the supporting structure in a pivotable manner around the horizontal axis, means to pivote this guide to and fro, two movable flattening elements which are mounted under the pivotable guide, on both sides of a vertical plane through the pivotating axis of the guide, and means to drive the flattening elements.
  • the device comprises a control device for controlling at least the cross-cutting device whereas the workstation contains a detector to detect marks applied on the web, which detector is connected to the control device.
  • the control device can precisely determine the moment to cut the web.
  • Other characteristics and advantages of the invention will become clear from the following description of a device for separating a web into parts and for stacking said parts, possibly after folding. This description is given by way of example only and without being limitative in any way.

  • the control device orders the starting of the stepping motor 25 as a result of which the web is moved downwards by the belts 23.
  • the motors 29, 41 and 43 are started.
  • the edges with perforations are cut off from the strip 6 by the longitudinal-cutting device 12.
  • the photo detector 47 has detected a mark or a random predetermined number of marks and the control device 20 has received corresponding signals
  • the latter orders the starting of the motor 35.

  • One or more web parts with a predetermined length can be laid down on one and the same stack.
  • the control device 20 orders the belt-conveyer 5 to move over a restricted distance by temporarily activating the stepping motor 46. Immediately thereafter, the device 20 moves the workstation 2 in its lowest position, just above the belt-conveyer 5, by activating the stepping motor 18 in the required revolving direction.
  • the guide 36 hangs vertically.
  • the control device 20 not only controls the starting of the motor 41 but determines also the direction of the pivoting movement when starting according to the choice of the user. Referring to figure 3, the guide 36 can thus be moved first to the right or first to the left.
  • the web 6 fed to the device may be pre-folded or not, the following possibilities are open.

  • one of the two flattening elements 42 can be horizontally moved as far as the vertical plane through the pivoting axis of the guide 36.
  • this removable flattening element 42 in the last-mentioned position no longer forms a flattening element but a rotating element to collect a sheet from the stationary guide 36 and to rotate this sheet down on the belt-conveyer 5 or on the sheets which have already been laid down upon it.

  • the removable lower ends of the side walls 10 are pushed upward towards the rest of the side walls and the movable flattening element 42 is placed symmetrically with regard to the other flattening element 42 with regard to the vertical plane through the pivoting axis of the guide 36.
  • the device works entirely as described above whereby the folding device 14 is activated or in other words the guide 36 pivots to and fro and the two elements 42 are flattening.
  • the folding device 14 For supplying loose, unfolded sheets, the folding device 14 must be switched off, which implies that it must be no longer possible to fold anything. To this end the guide 36 stands still in the vertical position. The movable flattening element 42 must be further rotated however, and the other flattening element 42 may be further rotated, but these elements 42 do no longer flatten. Moreover, the movable flattening element 42 must be placed under the guide 36 as represented in figure 4. Naturally, the control device 20 controls the cross-cutting device 13 such that the sheets are cut from the web 6 at the required length. These sheets frop through the slot 39 and are collected in the slot of the removable element 42 which does not function as a flattening element but as a rotating element and lays down the collected sheets on a stack.
  • the devices described above have a relatively simple construction. As the workstation 2 can be moved up and down and are stacking directly onto the belt-conveyer 5, successive stacks can be formed very fast one after the other such that the device can work very quickly.
  • the web 6 to be fed to the device may but must not be pre-folded or crosswise pre-perforated.
  • the successive stacks have not necessarily to be separated, or in other words the top sheet of a first sheet may be connected by web material to the lowermost sheet of the next stack.
  • the control device 20 has of course to control the stepping motor 35 of the cross-cutting device 13 accordingly so that the web 6 is not cut between the stacks which should be connected to each other.
  • the collecting device must not necessarily have a belt-conveyer.
  • Other transport devices with horizontally removable part such as for example a removable table, can be used.
  • the transport device of the workstation must not necessarily have pin tractors either.
  • the transport can also take place by means of pressure rolls, in which case the web must not be provided with perforations along its edges and the longitudinal-cutting device is of course redundant.
