Definitions

  • the present invention relates to a processing machine and to a method by which workpieces, for example packaging material made of cardboard or similar materials, can be processed.
  • Such processing machines such as board cutting machines, equipped with longitudinal and transverse tools.
  • longitudinal and transverse tools With these longitudinal and transverse tools blanks of variable blank type and dimensions with a lot size ⁇ 1 can be produced.
  • such machines can not produce Laschenok nicks, in which a piece of the carton blank is cut out flat. It is therefore state of the art to produce simple cuts in the packaging material instead of the mentioned tabs.
  • tab clearances improve process reliability in the case of further mechanical processing of the blanks, for example with so-called carton erectors.
  • carton erectors improve process reliability in the case of further mechanical processing of the blanks, for example with so-called carton erectors.
  • the folded out of the blank package is visually appealing.
  • punching tools are used in the prior art. Such punches are specially manufactured for specific dimensions and types of packaging material to be processed, and are relatively expensive. Furthermore, it results from the use of stamping tools the disadvantage that these specify the arrangement and geometry of the Laschenoknnitte. As a result, such devices are not flexible to new requirements adjustable.
  • the aim of the present invention is to provide a processing machine and a method by means of which, among other things, tab clearances can be realized in a more flexible and cost-effective manner.
  • the first cutting device is combined with a transverse tool, and the second cutting device with a longitudinal tool.
  • the material of the workpieces may comprise or consist of cardboard.
  • the material is not necessarily on a paperboard and / or paper material limited, but in principle relates to any foldable material into which a tab-free cut can be introduced.
  • the present invention relates to a processing machine according to claim 1.
  • a cutting processing tab free cutting
  • this processing machine it is possible with this processing machine to produce packaging in small batch production or batch size ⁇ 1 cost.
  • these can be introduced without tool change and additional costs during the production of the package blank, regardless of the type of packaging and its size. Since the cutting devices for producing a tab clearance can be delivered on demand, packaging blanks can also be produced without tab clearances. Accordingly, the present machine has a very high flexibility.
  • the cutting knife pair has two circular cutting blades arranged in parallel in the second direction, which are preferably guided in a common axis extending in the second direction.
  • a pressure roller may be provided, which is preferably guided with at least one of the cutting blade of the cutting blade pair on a common axis.

Furthermore, it is ensured that no slippage occurs between the workpiece and a guide and / or conveying device (eg conveying roller) provided underneath the workpiece.
  • the pressure rollers and the pair of cutting blades of the longitudinal tools are provided in mirror image in the second direction.
  • the pressure rollers have away from each other.

  • the second cutting device can be attached to the cutting tool pair with the longitudinal tool.
  • the cross tool / longitudinal tool can be shared by the first and second cutting device. This relates in particular to the positioning of the punching blade of the first cutting device and the positioning of the cutting blade pair of the second cutting device.
  • the first cutting device with the punching knife can perform a machining on the workpiece on a certain line, which is also used by the transverse tool for cutting, grooves and / or perforations.
  • the second cutting device may also perform machining along a line that is also used by the first longitudinal tool for cutting, creasing and / or perforating.
  • the cutting blade pair of the second cutting device can extend substantially in a processing line with the tool of the longitudinal tool. This means, for example, that the cutting blades of the cutting knife pair mirrored to Machining line of the tool of the longitudinal tool are aligned. Also, one of the blades could be along the processing line or close to it while the other is aligned parallel to it.

  • the processing machine may comprise a conveyor roller, with which the workpiece is moved relative to the transverse tool, the longitudinal tool and the first and second cutting device. This arrangement allows rapid processing of workpieces.
  • two longitudinal tools and two second cutting devices are provided as an assembly.
  • the two longitudinal tools and the two second cutting devices can be provided at defined positions, which usually define a distance of tabs.
  • the first cutting device with the Punching knife is attached to a cross tool so that the punch blade can perform a machining substantially on a processing line of the tool of the cross tool. Accordingly, a common movement of the combined with the cross tool first cutting device can be used for a machining.
