Definitions
- the invention relates to a cutting machine, in particular Tread cutting machine, with at least one on a knife carriage Achieving a feed movement linearly movable and by a motor rotating driven cutting knife according to the preamble of claim 1.
- a cross-cutting device for textile webs is known from the generic DE 38 06 645 C2, which has a rotating, disc-shaped cutting knife.
- the Cutting knife is mounted on a knife carriage, which is used to achieve a Feed movement is linear.
- the motor for driving the Cutting knife is permanently mounted outside the knife carriage and is by an as Endless belt designed torque transmission means with drive technology coupled to the cutting knife.
- To be able to move the knife carriage is a additional endless belt provided, which is also from an outside of the Knife carriage arranged motor can be driven and the fixed to the Knife carriage is clamped.
- the object of the invention is to provide a cutting machine of the generic type to improve in that a highly dynamic feed movement of Knife carriage is guaranteed with a long service life of the drive system, wherein the construction effort required for this should be comparatively low.
- the present invention is based on the knowledge that the mass of the Usually designed as an electric motor drive system for the rotating Cutting knife the essential determining factor for the total mass of the Knife carriage in the usual design.
- the invention resolves from the idea that the drive motor is absolutely on the knife carriage arranged and must be moved together with it, and sees instead that the knife drive motor is outside the knife carriage, i.e. stationary is arranged.
- a torque transmission means is provided which is characterized by that part of the torque transmission means that is with the knife carriage must be moved, has a significantly lower mass than the stationary installed motor. This will drastically reduce the overall weight of the Knife carriage accessible. This weight reduction in turn enables one considerable improvement in the dynamics of the feed movement, since the forces for Accelerating or braking the knife carriage correspondingly significantly less fail.
- the torque transmission means is a means for transmission trained by tensile forces, for example as a chain, rope or belt.
- the formation of the torque transmission means as circumferential toothed belt with which a corresponding toothed pulley interacts, which is arranged on the drive shaft of the cutting knife.
- the Torque transmission means or the toothed belt is arranged so that it or it runs over the knife carriage and its direction of movement outside the Knife carriage essentially parallel to the feed movement of the Cutting knife, that is parallel to the direction of travel of the knife carriage. So that is the knife carriage along the extent of the torque transmission means slidable without interrupting the torque transmission must be accepted at any time.
- the speed of the cutting knife is kept constantly constant. This can be done accomplish particularly simply in that an actual value detection of Knife speed occurs and this signal to a speed control of the motor is given.
- a speed control it is also possible to control the knife speed be provided, the motor of the knife depending on the target value of the Feed speed, the feed direction and the gear ratio of the Timing belt is controlled.
- the invention brings a drastic reduction in mechanical loads on the belt drive (e.g. toothed belt) due to Acceleration forces (no change in the knife speed) with itself. This works especially because of the high number of cutting processes, e.g. at 7 million Piece / year is significantly dependent on the security of trouble-free operation without Repairs.
- the cutting machine according to the invention with a Vibrating device is equipped, by means of which the cutting knife through a Tilting movement can be brought from the cutting position into a neutral position and vice versa.
- a can be used to actuate this oscillating device Hydraulic or pneumatic cylinder system can be provided.
- Hydraulic or pneumatic cylinder system can be provided.
- the tilting movement takes place thereby about an axis which is essentially coaxial to the direction of movement of the Torque transmission means is aligned. This causes it to tip over only for a corresponding slight twisting of the Torque transmission means that is easily tolerable and neither Torque transmission interferes, even to an impairment of the Torque transmission means itself leads.
- an adjusting device for adjusting the Cutting angle of the cutting knife provided, which is also, for example, by a hydraulic or pneumatic cylinder system can be actuated.
- the cutting machine shown schematically in Figure 1 is for the cutting of Tread provided in the manufacture of vehicle tires.
- the Treads are from the right over a conveyor belt 13 to the cutting area of the Cutting machine transported and divided there across the direction of transport.
- the cut off sections of the tread are each after cutting over a system of conveyor rollers 14 transported for further processing.
- the centerpiece the cutting machine consists of the knife carriage 1, the exact structure of which the top view of Figure 2 can be seen better.
- the knife carriage 1 is using a motor-driven linear unit, for example with a spindle drive is provided, movable on a portal-like superstructure that extends across the the conveyor track 13 and the conveyor rollers 14 formed transport path.
- a rotating knife 8 is arranged, the cutting plane the tread is inclined obliquely to the transport plane, as can be seen from FIG.
- the linear unit generates a feed movement for the cutting process, which is directed across the transport plane of the tread. This creates Portions of the tread, which each have a wedge-shaped at their ends Have cut surface.
- the entire knife carriage 1 and the linear unit can be pivoted about a pivot axis 9 so that the cutting angle the respective Needs can be adjusted. Because such a change of attitude only rarely has to be done, this setting is preferably manual vorappelbar.
- the tread to be cut is cut through during cutting one by means of e.g. pneumatic pressure cylinder system 11 actuated Hold down fixed in position.
- the rotating knife 8 is standing on the knife carriage 1 at the lower end arranged knife shaft attached, according to the desired Cutting angle is slightly inclined to the vertical.
- a toothed disc 4 is connected to the knife shaft in a rotationally fixed manner.
- the Drive motor 2, preferably an electric motor, is stationary in the left part of the portal-like superstructure arranged, as can be seen from Figure 2.
- the engine 2 is on its drive shaft with a drive roller 3, which has a rotating Timing belt 7 drives.
- the toothed belt 7 extends straight from the drive roller 3 to to a deflection roller 5 on the opposite right side of the portal-like Superstructure, is deflected there on a deflection roller 5 by 180 ° and runs over the Knife carriage 1 back to drive roller 3.
- the timing belt is located over a circumferential angle of (in the illustrated embodiment) more than 90 ° in Engagement with the pulley 4.
- the knife carriage 1 must Execution of a cutting process in each case returned to its starting position become. So that the continuously rotating knife 8 at such an idle stroke Reaching the starting position not just through the cutting area transported tread damaged, the rotating knife 8 from his Cutting position swiveled into a neutral position.
- swivel cylinder 10 provided that the knife 8 with the knife shaft and the toothed disk 4 by a Swivel axis 9 pivots so that the knife 8 comes out of engagement and safely can be driven over the tread.
- the inventive arrangement of the drive motor at a point outside of the moving knife carriage it is possible to change the weight of the knife carriage about 40% compared to the conventional construction of tread cutting machines to reduce, which provides an arrangement of the motor on the knife carriage.
- As a result of the drastic weight savings and by keeping the weight constant Knife speed are the forces for accelerating or braking the Knife carriage significantly lower. This makes it possible to set the speed for the method of the knife carriage, especially during an empty stroke Reaching the starting position to increase significantly, so that the Performance of the entire cutting machine can be increased significantly.
