Definitions

  • the invention relates to a method and an apparatus for sharpening the Cutting knife of a chipper. It is particularly about Knife ring chipper for processing wood into chips that are industrial can be further processed, for example as a starting material for Chipboard.
  • Such chippers have a knife ring that has a variety of Carrying knife packs.
  • the knife packs are arranged such that the Cutting the knives run parallel to the axis of the knife ring.
  • she each include a cutting knife with its cutting edge protruding inwards, and a clamping plate to which the knife is fixed by screwing.
  • a rotor rotates inside the knife.
  • a Wood chips flow introduced, which from the rotor to the outside against the cutting edges the knife is thrown.
  • the desired chip thickness results from the distance between the knife the so-called wear plates, which in turn are part of the knife ring are.
  • Knife basket can be rotated around its own axis.
  • the blunt knives are released from their clamp holder in the knife basket and on the to Regrinding the knives necessary work board set.
  • Then be the knives are ground and then tightened again in the knife basket.
  • the Grinding is carried out using a grinding tool which has one or more Includes grinding wheels.
  • the grinder moves parallel to the axis of the Knife body. If the tool has several grinding wheels, these are arranged side by side and all in use at the same time.
  • the knife ring will now rotated after each grinding cycle until the knives are complete are sharpened.
  • Machines of this type have proven themselves in principle. Your construction effort is however, high, and with it the manufacturing costs of the chip material. In addition, the machine can only be used when the machine is operating correctly and completely operate certain types of knife rings efficiently.
  • the invention has for its object a method and an apparatus to develop with which a perfect, quick and rational sharpening the worn knife can be reached, and with what also the technological requirements for the quality of the shredding are met, even if the operation is not trouble-free. Furthermore should The knives of different knife ring types are also sharpened in a rational way can be. Finally, the manufacturing cost of the product is said to be Chip material should be as low as possible.
  • the knife ring is removed from the knife ring chipper.
  • the knife packs are dismantled, i.e. the individual knife is removed from its clamping plate separated, and sharpened.
  • Important process steps are the intermediate storage of the blunt and the sharpened knives in a buffer station.
  • This has the advantage that the Sharpening process can be decoupled from the assembly process and thus a lower cycle time is reached. Cycle time is the time for entering a blunt knife pack until a sharp knife pack is issued from the Investment.
  • This procedure of disassembling or assembling the knife pack has the further advantage that the resinification between knife and Clamping plate can be removed during cleaning after dismantling and each depending on the state of wear of the cutting blades, they are removed and replaced can be.
  • the blunt knives are fed to a grinding device, the one certain dimension grinds or after a wear measurement of the Cutting knife contour can independently determine the grinding size.
  • the sharpening process could also be carried out by other cutting, thermal or physico-chemical processes can be realized. Grinding one single knife is more time consuming, but gives the possibility of individual grinding dimension input. This has the advantage that the knife is longer remains in the production cycle before it is too small is removed. The operating hours per knife are clear elevated. With a number of, for example, 60 cutting knives in one Knife ring can thus reduce the cost per knife ring.
  • the Clamping plate is not replaced in the entire process and is replaced online by the Processing line passed through. Exceptions are heavily worn out Clamping plates that are replaced manually by the operator.
  • the knives are stored in the buffer station with a certain inclination, to avoid a possible tilting of the knives with each other. Through the Inclination, the center of gravity of the knives is shifted, creating a safe Stacking the various wide knives is ensured.
  • An adjusting device takes the knife packs over specified Pick-up points that differ depending on the type of knife ring and the Knife package can be adapted. This has the advantage of being low Conversion effort any type of knife package can be processed with the system can and thus guarantees a high degree of flexibility towards the customer can be. It is also possible to have components consisting of several Components to machine with this machine.
  • the clamping plate is disengaged throughout Assembly process clamped firmly on an assembly slide. Because of the very exact drive of the assembly carriage can high adjustment accuracy for the Setting the knife board can be achieved.
  • the device according to the invention is designed accordingly that with it The inventive method can be carried out.
  • the receiving device enables the knife ring to clock its axis of rotation by a certain angle or to let it rotate continuously.
  • the clock frequency of the ring can be set individually by Operator can be set before and during disassembly or assembly.
  • the operator's workplace is based on workplace design guidelines aligned.
  • the delivery or take-up belt for the knife packages is at the operator's working height. This design of the workplace enables fatigue-free and body-friendly work for the operator.
  • the processing machine works as follows:
  • the knife ring is removed from the knife ring chipper and into a Receiving device 1 used and fixed.
  • the operator makes the necessary default settings (knife board, Cycle frequency, grinding dimension), dismantles the knife packs and places them on Conveyor belt that conveys them to the processing machine.
  • Knife packages thoroughly cleaned and brought into their processing position.
  • the Cutting knives point upwards.
  • the conveyor system 7 takes the individual Knife package and places it on an adjustment slide 8.1.
  • the adjustment slide 8.1 is or translationally moved within the adjustment unit 8 positioned and has additional functions to hold and fix the Knife pack and the clamping plate.
  • the knife pack is now over corresponding recordings 8.2 fixed and tensioned. After that, the position of the Square screws determined and the adjustment slide 8.1 to the position of the Feed screwdriver 8.3 driven.
  • the sharpened knife package is released from the adjusting slide 8.1 and removed from the conveyor system 7. After that, it will be on handover 12 filed and fed to a further knife package magazine 13. There it will be stored and turned to its mounting position (cutting knife is below). The The sharpened knife package is now from the Knife package magazine 13 outsourced and the operator on a conveyor belt 14 provided in the receiving position.
