Definitions

  • the invention relates to a device with tool modules for processing, in particular for cutting, flat objects, such as paper sheets, cardboard, or plastic films.
  • [3] discloses processing modules with tool modules for cutting sheets of paper, which have an upper housing part for holding an upper rotary blade and a lower housing part for holding a lower rotary blade.
  • the upper and lower housing parts of the tool modules are detachably connected to one another by a connecting plate.
  • the rotary blades are supported on one side in such a way that their cutting edges interact peripherally and can divide a sheet of paper passed between the housing parts.
  • Two bearing shafts are passed through the upper housing part and a drive shaft is passed through the lower housing part and the lower rotary blade.
  • the lower rotary blade is therefore driven and causes the upper rotary blade to rotate during operation.
  • the machining module in question is removed from the device.
  • Screws are then loosened from bearing elements on the machining module so that the two bearing shafts and the drive shaft can be removed from the machining module and neither inserted in order to remove and reinsert the tool modules that are held manually during this process.
  • the tool modules When inserting the bearing shafts and the drive shaft, the tool modules must be held in the appropriate positions while the drive shaft and the two adjusting shafts are inserted.
  • the bearing elements are then screwed back on and the processing module is reinstalled.
  • the process for exchanging the tool modules therefore includes numerous work steps that require technical knowledge, skill and a relatively large amount of time.
  • the tool modules can be moved to any position along the bearing shafts and the drive shaft by means of a threaded shaft.
  • the housing of the tool modules includes a forked wheel, which is pierced by the threaded shaft and which can be rotated automatically by means of a drive motor, and can thereby move along the threaded shaft together with the tool module.
  • the tool module must therefore be equipped with a drive motor and fed with electrical energy so that automatic displacement is made possible.
  • the automated tool modules are therefore designed to be relatively complex. It should also be noted that to replace the automated tool modules, the threaded shaft must also be loosened and reassembled, which increases the effort accordingly.
  • the object of the present invention is therefore to create an improved device with tool modules for processing, in particular for cutting, flat objects.
  • the device should be simple in design, require little maintenance and be configured and operated with little effort.
  • the disassembly and assembly of the tool modules should be easy to carry out with little effort. Maintenance work or changes in the configuration of the device for carrying out different machining operations should be able to be carried out quickly and easily with only a few work steps.
  • the device is intended to allow the guiding and processing of the flat objects to be carried out with high precision and high quality.
  • the cuts should be made precisely, while the flat objects are treated gently.
  • a high processing quality should be achieved without having to make adjustments beforehand.
  • the tool module is placed on a tool carrier which can be displaced parallel to the one or parallel to the lower and the upper drive shaft by means of a rotatably mounted actuating shaft and which has at least one holding element which serves to detachably hold the tool module.
  • One or the lower and upper drive shaft can thus be released from the coupled tool module or from a plurality of tool modules coupled thereto, while the tool module or the tool modules are held by the associated tool carrier (see Fig. 2b ). Since the control shafts are connected to the tool carriers, the tool modules can be changed without removing the control shafts. The tool modules can therefore be released by the at least one drive shaft or the lower and the upper drive shaft are pulled out of the device.
  • the drive shafts can be pulled out of the device from the front, for example, without the tool modules held by the tool carriers having to be held otherwise, for example with one hand.
  • one or the lower and the upper drive shaft is rotatably and displaceably held in a front bearing plate on the front side and in a rear bearing plate on the rear side.
  • the one or the lower and the upper drive shaft are preferably provided on the front side with a closure piece which can be detachably coupled to a closure part held by the front bearing plate.
  • the rotatably mounted drive shafts are therefore held axially immovable.
  • the drive shafts can be conveniently pulled out of the device on the front and the tool modules can thereby be released.
  • the drive shafts can be conveniently pulled out of the device on the front and the tool modules can thereby be released.
  • the tool modules can now be conveniently gripped, detached from the tool carriers and, e.g. after carrying out maintenance work or reconfiguration, the tool carriers are reinserted.
  • the drive shafts can be pushed back into the device and coupled with the newly inserted tool modules. This process can also be carried out conveniently. If the drive shafts are axially guided, this can be done by simple axial displacement.
  • the exchange of tool modules can therefore be carried out sequentially in a few steps by selective access to individual parts of the device. Simultaneous access to several parts of the device, e.g. It is not necessary to hold the tool modules while the drive shafts are being pulled out or pushed in.
  • the position of the tool modules can be adjusted by actuating the adjusting shafts or motors connected to the adjusting shafts, as a result of which the tool carriers and the tool modules held with them can be moved automatically to the desired positions in order to fulfill the intended tasks there.
  • the tool carrier in a preferred embodiment comprises a slide part which can be displaced along a guide rail which is aligned parallel to the actuating shaft and parallel to one or the lower and the upper drive shaft.
  • the slide part is supported on the guide rail and / or positively connected to the guide rail.
  • the slide part preferably has a receiving channel on the side facing the guide rail, into which the guide rail can be inserted.
  • the receiving channel and the guide rail preferably have cross sections which correspond to one another and which engage in one another in a form-fitting manner.
  • the guide rail has a T-shaped cross section, which is held in a form-fitting manner within the receiving channel.
  • the tool holder is therefore kept stable.
  • the tool modules are operated, they are supported by the tool holder, so that the machining processes, in particular cutting processes, can be carried out precisely.
  • the tool carrier can have any holding elements by means of which the tool modules can be held reliably, preferably without play.
  • the tool carrier has a collar into which a base provided on the underside of the tool module can be inserted.
  • locking elements can be provided that allow the tool modules to be locked in the tool carriers and released again with the action of force.
  • the base can be enclosed by an elastic ring which can snap into a circumferential groove or into groove elements on the inside of the collar.
  • Magnetic elements are preferably provided on the tool module and on the associated tool carrier, which attract each other.
  • the tool carrier can, for example, be provided with at least one permanent magnet which interacts with ferromagnetic or paramagnetic elements of the tool module.
  • the permanent magnet can also be connected to the tool module.
  • the tool module and the tool carrier can each be provided with a permanent magnet, but this is associated with somewhat more effort.
  • the holding elements are preferably used in combination.
  • the mechanical holding elements are preferably used for the form-fitting lateral holding and supporting the tool module, while the at least one magnetic holding element has the effect that the tool modules can only be lifted vertically with the appropriate effort.
  • the tool module has a lower module part with a lower tool part, which is detachably coupled to the lower drive shaft, and an upper module part with an upper tool part, which is detachably coupled to the upper drive shaft.
  • the lower tool part and the upper tool part preferably have identical diameters, which are selected such that the lower tool part can act on the flat object from below and the upper tool part from above.
  • the processing of the flat object e.g. of a sheet of paper is done with the greatest precision when the flat object is aligned in one plane.
  • the action of the tool parts on the flat object can deform it, so that the quality of the processing of the flat object is impaired.
  • the invention provides that the lower tool module has at least one lower guide wheel which is detachably coupled to the lower drive shaft, and that the upper tool module has at least one upper guide wheel which is detachably coupled to the upper drive shaft.
  • the lower and the upper guide wheel preferably have identical diameters which are selected such that the lower guide wheel can act on the flat object from below and the upper guide wheel from above. Since the guide wheels are only a short distance of e.g. Are shifted 5 mm to 25 mm relative to the tool parts, it is ensured that the flat object in the area of the tool parts is guided in one plane. The flat object held in one plane can therefore be processed with maximum precision.
  • the lower module part preferably has at least one lower rotary body which holds the lower tool part and / or the lower guide wheel and which has a lower drive channel, within which the lower drive shaft is positively, but is held axially displaceable.
  • the upper module part preferably has at least one upper rotary body which holds the upper tool part and / or the upper guide wheel and which has an upper drive channel within which the upper drive shaft is held in a form-fitting manner but axially displaceably.
  • The, for example, annular tool parts can therefore be adapted to the rotating body, which in turn interacts with the associated drive shaft in a form-fitting manner. In this way For example, tool parts that are normally made of high-quality materials can have simpler and smaller dimensions.
  • Flat objects can be grooved, perforated or cut.
  • Different configured tool modules can be used so that different machining processes can be combined.
  • the device according to the invention can be designed and used particularly advantageously for cutting flat objects.
  • the lower and the upper tool part are designed as rotating blades or rotating blades.
  • the rotary blades have peripheral cutting edges, which can act on the flat objects from above and below. The cutting edges preferably overlap so that the flat object can be completely severed. It is also possible for only one of the blades to penetrate the transport plane along which the flat objects are transported.
  • the rotary blades can be designed identically and have identical functions. However, the blades can be designed in any way so that cutting processes and shearing processes can be carried out. Both tool parts or both rotary blades are preferably driven directly. However, one of the tool parts can also be used as a follower.
  • the tool module has a casing with a central shell, which has a lower central shell part provided with a lower central opening and an upper central shell part provided with an upper central opening.
  • the central shell parts are connected to one another in one piece by a connecting web.
  • the connecting web connects in the transport direction on the input side to a working channel into which the lower tool part arranged in the lower central opening and the upper tool part arranged in the upper central opening project peripherally.
  • the connecting web connects on the output side to a first output channel on its underside and to a second output channel on its top side.
  • Flat objects that are transported in the transport direction through an input channel into the tool module are cut open in the working channel and separated into two object parts, of which the first object part through the first output channel and the second object part through the second output channel are routed away.
  • the one-piece connection of the two central shell parts results in a precise arrangement of the tool parts and the guide rollers.
  • the flat objects can be processed precisely without the need for adjustments beforehand. Due to the one-piece construction of the central shell part, it can be machined with little effort, without further assembly work subsequently being required.
  • the lower and the upper central shell part can also be manufactured separately and releasably connected to one another by mechanical elements. For high-precision devices, however, one-piece central shell parts are preferred.
  • separated object parts can be processed further or also taken away.
  • An object part, which forms the edge of a flat object, is usually not processed further, but is carried away as waste. Such waste is usually carried down into a container which is emptied from time to time.
  • the tool modules are therefore to be designed according to the work process or purpose. Conventionally, therefore, tool modules that are used to cut the edge sections and tool modules that are used to make longitudinal cuts are provided.
  • a conventional cutting device is therefore ordered with a large number of tool modules, each of which has a specific purpose and which are used selectively. This is associated with a corresponding cost for the manufacture, procurement and storage of the numerous tool modules.
  • the invention provides that the lower central shell part has a lower receiving space in which a lower guide shell is fastened, and that the upper central shell part has an upper receiving space in which an upper guide shell is arranged. It is further provided that the lower guide shell and the upper guide shell limit the first output channel through which an object part is led away or continued.

  • a tool module can therefore be converted in just a few minutes by replacing the guide shells.
  • the user of the device therefore does not have to have a large number of tool modules available, but can do so Adapt tool modules to a current machining process within a short time by exchanging the guide shell.
