Definitions
- 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 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 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.
- control device can precisely determine the moment to cut the web.
- the longitudinal-cutting device 12 contains two disc-shaped knives 26 which have been fixed on a horizontal shaft 27 opposite supports 28.
- the shaft 27 which is borne in the side walls 10 is driven by a motor 29.
- the cross-cutting device 13 contains two horizontal knives directed crosswise to the side walls 10, namely a fixed knife 30 and a knife 31 which can move with regard to the latter.
- the knife 31 works in conjuction with a cam disc 32 which can push this knife against the action of a spring 33 against the fixed knife 30 to cut the web 6.
- the cam disc 32 is fixed on a shaft 34 which is driven by a stepping motor 35.
- the folding device 14 also contains two flattening elements 42 which have been mounted under the guide 36 on both sides of the theoretically vertical plane through the pivoting axis of the guide 36, at the same height, in a rotatable manner between the lower ends of the side walls 10. These elements 42 extend parallel to the pivoting axis of the guide 36. Perpendicular to their rotating axis, these flattening elements 42 have a practically half circle shaped section whereby one element 42 has been turned 180 degrees with regard to the other.
- the two rotatable flattening elements 42 are driven by stepping motors 43.
- the belt-conveyer 5 of the collecting device 3 consists of an actual endless belt which runs over two rolls 45 borne in the frame 4, with the topmost belt portion 44 horizontally.
- One of the rolls 45 is driven by a motor 46.
- This control device is also connected to a photo detector 47 which is mounted right above the cross-cutting device 13 and which can detects marks which have been applied on the web 6 by the printing device.
- the web 6 is inserted between the guide plate 22 and the endless belts 23 with the pins through the perforations along the edges of the web 6.
- 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.
- the cam disc 32 is rotated one turn which results in the moveable knife 31 being pushed against the fixed knife 30 and the web 6 being cut.
- the control device 20 orders the motors 25 and 29 to stop such that the web 6 comes to a standstill.
- the cut-off web part drops in the slot 39.
- the control device 20 controls the stepping motor 41 such that the guide 36 pivots to and fro as a result of which this web part is laid in a zigzag manner on the belt-conveyer 5 which is hold stationary or on a stack which has already been placed upon it. Successively, the folds are pressed on either side by the flattening elements 42 which are rotated by the motors 43 at the same speed.
- 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 web When a not folded continuous web 6 is treated, the web may be folded with the upside of the sheets of forms upside after folding or downside after folding. So, if e.g. the web is printed on one side, the device can fold the web so that the printed side of the first form of the folded web is downside or is upside.
- the two flattening elements 42 can be adjusted in the height with regard to the guide 36 as they are mounted between the lower parts of the side walls 10 which are not fixed to the rest and which can be adjusted in the heigth with regard to the rest by means of cylinder piston mechanisms 48.
- 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 element 42 has been provided with a slot 49 in the longitudinal direction which opens on its outer surface, as represented in figure 4.
- the device provided with the workstation 2 according to the embodiment in figure 4 can supply stacks with one or more folded web parts as well as stackes with loose sheets.
- 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 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 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.
