Definitions

  • the invention relates to a device or units for processing sheet material or the like, in particular substrate materials.
  • sheet-like materials can consist of paper, plastics or the like and are of relatively great flexibility, so that they can be folded without breaking or can be closely curved with a radius of a few millimeters without permanent permanent deformation.
  • the material can be fed as a web from a storage unit, for example a roll and / or folded-layer storage unit, and can be subjected to successive different treatments or processing steps in a single or several workstations, for example in such a way that individual and separate sheet layers are created at the end , which in turn can be combined in several layers. In the case of multiple layers, the individual layers can run through the device jointly or almost congruently despite different processing.
  • the layer material can also be fed to the device in the form of individual sheet layers or blanks or as a strand of sheet layers.

  • prefabricated or separately manufactured product parts such as viewing window films, longitudinal strips or the like, can be brought together with the layer material.
  • Sheet layers or web sections can also be brought together, e.g. overlapping each other or almost flush to form multiple sets, or finished articles or products can be placed in a packaging and thereby packed.
  • Driven tools are usually required for the treatments mentioned, but work stations can also be provided in which treatment does not require a tool drive, but only the conveying movement of the sheet material, such as e.g. when folding, merging, deflecting or turning.
  • any work units should be interchangeable or interchangeable with others, and the number of existing work units or the length of the facility should be changeable. Since the work units and, if applicable, funding are usually to be driven in a mutual dependency or jointly, the associated drive or control means should also be able to be changed in a corresponding manner.
  • the base frame which mainly determines the fixed assignment of the work units and their spacing above the floor and may contain drive and control means.
  • the invention has for its object to provide a device, in particular a work unit and / or a base unit, in which disadvantages of known designs can be avoided and advantages of the type mentioned can be achieved, in particular by simple assembly or interchangeability, a diverse structure of individual pre-assembled or essentially ready-to-use modules should be possible.
  • At least one subunit of the respective work unit is designed as a slide-in unit which has guide and support means such that it can be brought together with the base frame and supported by it from a state completely separated from the base frame and then guided on the base frame until it can be moved into its working position, after which the insert is to be fixed in its working position by tensioning or the like relative to the base frame.
  • the insertion direction is expediently transverse or at right angles to the conveying direction, approximately parallel to the associated running plane of the layer material and / or the insertion direction deviates from the vertical, an approximately horizontal insertion direction being particularly expedient.

  • the insert is expedient essentially completely above the top of the base frame, so that there is an approximately parallel or horizontal separating plane between them, in the area of which the interlocking assembly coupling members of the insert and base frame are located.
  • the guide or coupling members of the slide-in unit can thereby lie on the bottom outside thereof, while the corresponding members of the base frame can lie on its top side.
  • centering, clamping or adjusting means with which the insert as a whole is to be aligned and fixed in relation to the base frame.
  • the insert is expediently detachable or easily detachable and attachable like other assemblies of the device.
  • This is to be understood as releasable or attachable, which is non-destructive, the actuation in the working position or in the disassembled position is freely accessible from the outside, the actuation of which is essentially drive-free or tool-free or possible by hand, the releasable connection being at least partially can be self-engaging due to the insertion movement or self-disengaging due to the opposite extension movement.
  • the above-mentioned links are advantageously designed so that the insert can initially carry out the insertion movement essentially continuously or steplessly without or with side guidance relative to the base frame, then towards the end of the insertion movement by centering or the like in or against the insertion direction under its weight is locked that an increased to overcome the rest Thrust is required, according to which the slide-in is adjustable in several directions in comparison to the slide-in travel and finally fixed in the adjusted position relative to the base frame.

  • the insert is expediently designed such that its underside or its members form a standing surface with which the insert can be placed on a flat shelf without damage to any components and thus stored. If the slide-in unit has protruding, rolling and track-holding running elements on its underside, it can be moved easily on the base frame as well as on the shelf as a carriage and can thus be brought into any desired position. At least three or at most four running elements lying at the corners of an imaginary rectangle can provide the only weight support for the insert relative to the base frame or the standing surface and / or can form skids for transverse displacement of the insert relative to each of the mentioned standing surfaces.
  • the respective insert expediently has a rigidly pre-assembled frame with plate-shaped side walls at the ends, the side walls being stiffened with respect to one another by rigid connections and the frame or side walls being used for fastening or for storing tools which are in side and / or longitudinal view of the device are all completely outside the base frame and at a distance from it.

  • the working unit expediently forms, for example, a gap-shaped passage for the layer material between its frame cheeks, in which this layer material is guided or treated in the associated conveying plane or processed in a continuous pass.
