Description

[Detailed description of the invention] Separating the web into parts and stacking the parts after folding as necessary sleeping device The present invention separates the web into multiple parts and folds the parts as necessary. and a stacking device, said device comprising a support structure and a web feeding device. a work station having a separator, and a separation device mounted on the support structure. comprising a folding device, further accumulating said web portions into a stack; an accumulating device, said accumulating device;

located below said work station and at least It consists of a horizontally movable part and a device for moving this part.

Such devices are often installed after the printing device, especially in series. There are many. The folding device used for this purpose folds the web part into a zigzag pattern on a table. , or already exists on this platform and its fold flattening component. It is equipped with a well-known device for laying over the web section. In addition, these planarization configuration elements The material is actually located at the height of the said platform or the stack already placed on it. I have to be there. Stacking is when one web section or multiple web sections You can also move the work station and the table relative to each other as they are placed on the table. Must be possible.

A device of this type is known from EP-A-0187344. This known In this case, the work station is stationary and the platform can be moved up and down. pile up Before the mold is formed on the platform, the platform is raised relative to the work station. The accumulation is The higher the height, the lower the pedestal (becomes. If the stack is quite high, the pedestal will The height of the moving parts is lowered. This actuation mechanism allows the stacking to finally occur between the two pushed out from the base of the movable part of.

To form a relatively high stack, the distance between the platform and the work station is , relatively thick (larger than the tallest stack accumulated by the accumulator). However, if a low stack is required, the platform is relatively large after the stack is formed. Descend the distance to the height of the horizontal movement part. This means a loss of time. This structure of pressing the layers makes the structure of the device even more complicated, and this extrusion is It also requires extra time.

Moreover, in this known device, the separating device is a device for tearing the web. The cracking device consists of a mechanism that holds the web and a mechanism located upstream of the web that moves backwards. It consists of a fixed drive unit. The web has transverse perforations for tearing. must be included. In fact, this known device can Simply tear off the pre-folded web with thin edges. for each tear The motion of the web must be reversed so that the web is not torn at the fold line. Forming stacks that are separate from the web is not recommended because It always takes time.

It is an object of the invention to overcome the above-mentioned disadvantages and to provide a relatively simple construction but rapid operation. Pre-folding or pre-folding can also be used when separate stacking is required. The present invention does not require perforations in the transverse direction of the web. To provide a device for separating and stacking the parts after folding as necessary. That's true.

For this purpose, a stack is formed directly on the part where the accumulator moves horizontally and the main The working station as a function of the height of the stack formed on the moving part of the device The separating device is a transverse cutting device, and the work A station can be moved up and down above the horizontal movement device.

The folding device moves up and down as a function of the height of the stack formed on a stationary platform. Web folding and stacking devices that are independently movable in It is known from No. A-4504,051. This device is a web separating device. It is used to form a stack from pre-folded webs. It is only used. Difficulties are seen when the crease marks disappear. On top of that , this folding device only consists of a guiding device without a flattening device.

The blade 31 is a cam disc 32 The cam disc 32 operates in connection with the fixed blade 3 for cutting the web 6. The blade 31 is pressed against the fixed blade 30 against the action of the blade 0.

The cam disc 32 is fixed to a shaft 34 driven by a step motor 35. ing.

The folding device 14 is an inducer that pivots two parallel downward facing plates 37 back and forth. The two plates are provided with a conductive portion 36 between the side walls 10. mutually attached to the top by means of a mounting 038 which is pivotably suspended about the horizontal axis of the is connected to. The upper part of the slot 39 between the plates 37 is located between the blades 30 and 31. It is located directly below the gap. A guide roll 40 is provided at the lower end of the plate 37. It is. One of the ports 38 is attached to a step motor 41 that rotates in both directions. more driven.

The folding device 14 also includes two flattening components 42, the components 42 are provided at the same height on both sides of a theoretically perpendicular plane passing through the rotation axis of the guiding part 36. It is mounted below the guiding part 36 so as to be rotatable between the lower ends of the wall 10. these The element 42 extends parallel to the axis of axial rotation of the guide section 36. flattening these The components 42 are approximately semicircular in cross section perpendicular to their axis of rotation and are 18 mm apart from each other. It is rotated by 0°. These two flattening components 42 are connected to a step motor 43. more driven.

The belt conveyor 5 of the accumulating device 3 carries the rolls 45 supported on the pedestal 4 to the top. The upper part 44 consists of an endless belt running horizontally. roll 4 5 is driven by a step motor 43.

Not only motor 18 but also motors 25, 29, 35° 41, 43 and 46 are rotated. ! 21 is connected to the control device 20.

This control device is also connected to a photodetector 47, which detector is connected to the transverse cutting device 13. It is mounted directly above and detects marks made on the web 6 by a printing device.

The web 6 is connected to the guide plate 2 by means of bins passing through perforations along both ends of the web. 2 and the endless belt 23. When the device is switched on , the controller commands the start of the step motor 25, so that the web 23 to move downward. At the same time, motors 29, 41 and 43 are also started.

The perforated edges are cut from the web 6 by a longitudinal cutting device 12. light detection The controller 47 detects a mark or a predetermined number of marks at random, and the control device 20 responds accordingly. Upon receiving this signal, device 20 instructs motor 35 to start. the result , the cam disk 32 rotates once, and the movable blade 31 presses against the fixed blade 30. , the web 6 is cut. During this cutting operation, the control device 20 causes the web 6 to stop. This instructs motors 25 and 29 to stop.

The cut web portion falls into the slot 39. The control device 20 is a step motor 41 to pivot the guiding portion 36 back and forth, so that this portion of the web , on a belt conveyor that is kept stationary or already on the belt. It is laid out in a zigzag pattern on top of the stacks placed on it.

Subsequently, the fold is flattened and rotated at the same speed by the motor 43. Either side of the elements 4'1 and I is pressed.

The stack above the top 44 of the belt of the endless belt conveyor becomes taller. and a flattening configuration to compress the folds of the zigzag web section. The control device 20 is installed at the work station so that the element 42 is always at the required height. The step motor 18 is activated to instruct the robot to ascend. One or more of the predetermined lengths The upper web portion can be laid in one identical stack.

Once the stack reaches a certain height, e.g. Once detected by counting the number of parts, folds or sheets, the control device 2 0, the belt conveyor 5 is constrained by temporarily operating the step motor 46. Instruct the driver to move the specified distance. Immediately thereafter, the device 20 operates the step motor 1 8 in the desired direction of rotation, and move the work station 2 to the center of the belt conveyor 5. Move to its lowest position above.

When the reciprocating shaft rotation movement of the guiding part 36 of the folding device 14 starts, the guiding part 36 is vertically moved. hang directly. The control device 20 not only controls the starting of the motor 41, but also controls the starting of the motor 41. When initiated by user selection, the direction of shaft rotation is also determined. Therefore, regarding Figure 3, However, the guiding part 36 can be moved first to the right or first to the left. outfit Considering whether the web 6 sent to the station is folded in advance or not, the following possibilities are considered. There is a potential. When the pre-folded web 6 is folded again, the same and crease Refolded with the same fold as the trace or the folded web is upstream of the device The marks are stacked upside down relative to the initial stack so that they can be stacked on the conveyor belt. The remaining crease will be reversed. When a continuous unfolded web 6 is processed , the web is folded top side up in the initial sheet format after folding, or Or, it will be folded downward after being folded.

Thus, for example, if the web is printed on one side, the first version of the folded web The printed side is either on the bottom or on the top.

The method of the embodiment of work station 2 shown in FIG. The folding device 14 differs from the embodiments in the previous figures in that the folding device 14 has a different structure. Different from the method.

In particular, if the flattening component 42 is not fixed to the rest and the cylinder-piston mechanism mounted between the lower parts of the side walls 10 adjustable in height with respect to the rest. Therefore, the two flattening components 42 can be adjusted in height with respect to the guiding part 36. I can do it. Moreover, one of the two flattening components 42 passes through the axis of rotation of the guiding section 36. It is possible to move horizontally up to a vertical plane. In fact, it is located in the last mentioned position. The movable flattening component 42 no longer forms a flattening component, but The conveyor belt is collected from the stationary guide section 36 and placed on the belt conveyor 5 or above. A rotating component that rotates and drops a sheet onto a sheet placed on a conveyor. It is. To this end, this movable component 42 is moved as shown in FIG. It is provided with a narrow hole 49 opening in the vertical direction on its outer surface.

This device with a working station 2 according to the embodiment of FIG. Feeds the separated web sections into the stack and also feeds the loose sheets into the stack You can.

To feed the folded web section, the movable lower end of the side wall IO The movable flattening component 42 is pushed upwardly towards the It is located symmetrically to the other flattening components with respect to the vertical plane passing through the axis of rotation. Device works perfectly as described above, the folding device is driven, in other words the guide part 3 6 pivots back and forth, and the two components 42 flatten.

The folding device 14 is turned off in order to supply loose, unfolded sheets. This means that the device 14 can no longer be folded in any way. It means no. For this reason, the guiding part 36 remains in a vertical position. Ru. However, the movable flattening component 42 must be rotated further. However, these components 42 no longer flatten. Moreover, a movable flattening structure Component 42 must be located below guide portion 36, as shown in FIG. Must be. Naturally, the control is such that the sheet is cut from the web 6 at a predetermined length. The device 20 controls the transverse cutting device 13 . These sheets are dropped through the slot 39. It is lowered and collected into the slot of the movable component 42. This component 42 is flattened Acts as a rotating component rather than a component, stacking the accumulated sheets Lay it on top (.

The device described above is of relatively simple construction. Work station 2 is up and down moving and stacking directly onto the belt conveyor 5, which allows the device to work very quickly. Successive stacks are formed one after the other fairly rapidly. Web 6 sent to the device may be pre-folded or laterally perforated; It shouldn't be.

Consecutive stacks do not necessarily have to be separated; in other words, the first stack The top sheet of the stack should be connected with the bottom sheet of the next stack with the nibs. I can do that. Of course, the webs 6 must be connected to each other. The control device 20 controls the steps of the transverse cutting device 13 so that they are not cut between the stacks. motor 35 must be controlled.

The present invention is in no way restricted to the embodiments described above. more than that , among other things, the form, composition, structure, and parts used to embody the present invention. Many modifications, as far as numbers are concerned, can be made to the scheme of the embodiments described above. However, this does not depart from the scope of the invention.

In particular, the accumulating device does not necessarily have to include a belt conveyor. For example, Other feeding devices with horizontally movable parts, such as movable platforms, may be used. Can be done.

The carriage of the work station does not necessarily have to have a bin puller. sheet Feeding can also be done by pressure rolls, in which case the web is provided with perforations along the edges. There must be no holes formed, and of course the longitudinal cutting device is redundant. be.
