Abstract
In order to provide a method and a disc cutter machine for carrying out the method with which the previously strenuous blade receiver exchange is simplified and facilitated, it is provided that the blade receiver (8) to be exchanged is tilted up by means of a tilting arrangement (19) with its end facing the outer side of the disc cutter, received by a guide (27) and drawn out substantially in the radial direction along the guide from the region of the disc cutter (6) and then the new blade receiver is inserted along the guide into the disc cutter.
Claims15
A method for exchanging a blade receiver in a disc cutter machine having a rotatable disc cutter with an axis and a periphery, the disc cutter including a blade receiver to be exchanged which is located in a radially extending position between the axis and the periphery of the disc cutter, the method comprising:
- (a) mechanically tilting up a peripherally located end of the blade receiver;
- (b) positioning a guide substantially radially with respect to the disc cutter for receiving the peripherally located end of the tilted blade receiver;
- (c) withdrawing the blade receiver from the disc cutter by drawing the tilted blade receiver away from the disc cutter along the guide, substantially in a radial direction with respect to the disc cutter;
- and
- (d) inserting a new blade receiver into the disc cutter by guiding the new blade receiver along said guide into said radially extending position between the axis and the periphery of the disc cutter.
In combination:
- (a) a disc cutter machine having a rotatable disc cutter with an axis and a periphery, the disc cutter including an exchangeable blade receiver in a radially extending position between the axis and the periphery of the disc cutter, and
- (b) means for exchanging the blade receiver, including means for tilting up a peripherally located end of the blade receiver, a blade receiver guide and means for supporting the blade receiver guide in a substantially radial position with respect to the disc cutter for receiving the peripherally located end of the blade receiver when tilted up, and for supporting and guiding a tilted blade receiver during substantially radial withdrawal of the blade receiver from, or insertion of a blade receiver into, the disc cutter.
