[0040] Below, the invention is explained in more detail with reference to the drawings. Thereby shows:

[0054] The housing 100 of apparatus 1, which is shown only schematically, preferably includes doors or windows that can be opened by sliding or hinged devices to access the relevant parts of apparatus 1 for setting, configuration and/or maintenance. Preferably, the side shown is accessible and the processing stages L1, L2, L3 are accessible from above.
[0055] Each of the processing stages L1, L2, L3 in this preferred embodiment of the apparatus 1 comprises two tool modules 2, which are equipped with interacting tool parts 211, 221 (see
[0056] The apparatus 1 comprises a transport system 4 (see
[0057] Below as an example tool modules 2 are described, which are provided for cutting flat objects. Likewise, tool modules 2 can be used to crease, perforate or otherwise process flat objects.
[0058] On the flat object 9 shown in
[0059] Depending on the cuts to be made, it is therefore possible that cut-off object parts 91, 92 can be moved to the next processing stage L2, L3, T or moved downwards. The deflection of the object parts 91, 92 can be done by sliders or advantageously by the tool modules 2 themselves.
[0060] The user can decide how the flat object 9 should be processed. Depending on the selected working process, apparatus 1 has to be configured. For this purpose, apparatus 1 is to be equipped with the appropriate tool modules 2, 2A, which are then moved to the positions where a cut is to be made by driving setting shafts 38, 39 in each processing stage L1, L2, L3. The processing stages L1, L2, L3 are to be equipped with the required number of tool modules 2 according to the defined cutting pattern. One or two tool modules 2 can be inserted in the shown apparatus. If further tool modules 2 are to be inserted, a corresponding number of additional setting shafts is required.
[0061] It is described below that tool modules 2 can be configured so that according to the selected configuration the separated object parts 91, 92 are forwarded to the next processing stage L2; L3, T or moved downwards and away.
[0062] As an example, it is shown that the tool module 2A executes the longitudinal cut S1, which separates the object parts 91, 92 from each other. The object part 91 is the separated edge of sheet 9, which should be led downwards and away. The object part 92 is a longitudinal strip that is divided into individual cards in the fourth processing stage T.
[0063] The fourth processing stage T serves therefore for making transverse cuts, in particular to separate the front and back edges of sheet 9 and to separate the longitudinal strips into individual cards K4. As an example, the cutting line Q1 is shown, along which the back edge of paper sheet 9 is cut off.
[0064] A control unit 8 is provided to monitor and control the processes taking into account the current configuration of apparatus 1. Sensors 81 are used to check which tool modules 2 are used. The identification can be optically, magnetically or electromagnetically. An identification program ensures that the tool modules 2 are moved aside to the sensors 81 and identified there. As soon as the configuration of the apparatus 1 with the tool modules 2 is determined, the tool modules 2 are moved according to the instructions selected by the user to the corresponding positions where the longitudinal cuts are to be made. For this purpose, the setting motors 61, 62 are operated by the control unit 8. Then the transport system 4 is activated with the main motor 45. For the correct execution of the longitudinal cuts and cross sections, additional sensors are preferably provided, which detect the position of the paper sheet 9 and control the processing stages L1, L2, L3, T accordingly.
[0065] The processing stages L1, L2, L3, T are held by a rack or chassis 10 of apparatus 1, which has a front mounting plate 11 and a rear mounting plate 12 connected by cross bars 13.
[0066]
[0067] The processing stage L3 has a front bearing plate 51 and a rear bearing plate 52, between which a lower and an upper drive shaft 28, 29; a lower and an upper setting shaft 38, 39; and a lower and an upper conveyor roller 41, 42 are rotatably mounted. The lower and upper drive shafts 28, 29 are supported on both sides in drive shaft bearings 280, 290. The lower and upper setting shaft 38, 39 are supported on both sides by setting shaft bearings 380, 390. In addition, a guide rail 37 is held stable between the front and rear bearing plate 51, 52.
[0068] As shown in
[0069]
[0070] Furthermore it is shown that the fourth processing stage T can be driven by an auxiliary belt 400.
[0071]
[0072]
[0073]
[0074] The upper and lower drive shafts 28, 29 can be pulled out of the unit 1, while the tool modules 2 rest on the corresponding tool carriers 3. For this purpose, a locking part 55 is released by turning a locking element 56 and is pushed aside and thereby released from a lower locking piece 289 provided on the front of the lower drive shaft 28 and from an upper locking piece 299 provided on the front of the upper drive shaft 29. The locking of the lower and upper drive shafts 28, 29 is thereby released so that they can be pulled out axially from the apparatus 1.
[0075]
[0076] The steps for removing the tool modules 2 are marked A, B and C. In step A (see
[0077]
[0078]
[0079]
[0080]
[0081] Each of the tool modules 2 has a five-part casing 7 with a central shell 71, to which a lower bearing shell 72 and an upper bearing shell 73 can be connected or screwed on one side and a lower guide shell 74 and an upper guide shell 75 on the other side.
[0082] As shown in
[0083] The lower and upper bearing shell 72, 73 are screwed to one side of the central shell 71. On the other side, the lower guide shell 74, which has a lower bearing opening 740, is inserted and screwed into the lower receiving chamber 7111. The upper guide shell 75, which has an upper bearing opening 750, is inserted and screwed into the upper receiving chamber 7121. The lower guide shell 74 and the upper guide shell 75 limit an output channel, which can be designed as required by the design of the guide shells 74, 75, e.g. an output channel which extends approximately straight or downward. Depending on the requirements, a lower and upper guide shell 74, 75 can be connected to the central shell 71 to define an output channel as required for the planned machining process.
[0084] The section through the second tool module 2 in parallel to the drive shafts 28, 29 in
[0085] The lower tool part 211 and the lower guide wheel 212 as well as the upper tool part 221 and the upper guide wheel 222 are therefore connected to each other in a stable way and are arranged close to each other. The flat object 9 is stably guided in one plane by the guide wheels 212, 222 and can therefore be precisely machined by the adjacent tool parts 211, 221.
[0086]
[0087] The tool module 2 is mounted on a tool carrier 3, which comprises the carriage 31 with the receiving channel 310 and the receiving part 32.
[0088]
[0089]
[0090]
[0091]
[0092] It is shown that the input channel 251 adjoins the working channel 252, which in turn adjoins the connecting bridge 715, which separates the first output channel 253 from the second output channel 254. Symbolically, different courses of the first output channel 253, 253 are shown.
