Definitions
- the invention relates to a knife holder for circular knives for longitudinally dividing material webs, in particular made of paper or plastic film, the circular knife being adjustable.
- a pressure-medium-operated knife holder for slitter-cutting machines which requires a single piston for the lowering movement and side adjustment, the circular knife being adjustable in the lateral direction by mechanical movement deflection, specifically via a side stop, the one Tilting the circular knife shift around a pivot point on the extended piston rod causes.
- a knife holder of this type proves to be disadvantageous in that the positioning movement cannot be controlled in a variable manner, but is predefined on the basis of the structural design.
- double cutter heads were used, as are known for example from DE-U-1 992 832, which have the disadvantage of a large overall width.
- the invention is therefore based on the object of providing a knife holder for circular knives which has a high degree of rigidity and good functional reliability with the smallest possible overall width and enables the circular knife to be reliably positioned relative to the lower knife.
- a knife holder for circular knives for longitudinally dividing material webs which has a base body which can be connected to a knife bar and which is assigned at least one displaceably mounted guide rod which is connected at one end to an actuator and which is connected to the other End is connected via a joint to at least one swivel arm, on which a cutter head with a rotatably mounted circular knife is arranged and which is connected to an actuating means.
- the knife holders are fixed to the knife bars with their base body at predetermined intervals, which depend on the desired cutting width.
- the circular knife which is rotatably mounted on the cutter head, is fed in that the guide rod, which is displaceably mounted in the base body, is moved via a pneumatic or hydraulic actuator, for example, in the direction of a lower knife assigned to the circular knife, so that the circular knife plunges into the intended groove of the lower knife.
- a pneumatic or hydraulic actuator for example, in the direction of a lower knife assigned to the circular knife, so that the circular knife plunges into the intended groove of the lower knife.
- the circular knife is turned against the lower knife to ensure a clean scissor cut.
- the lateral adjustment of the circular knife is achieved in that the knife head is arranged on a swivel arm which is connected to the guide is connected. When the specified immersion depth is reached, the swivel arm is adjusted via an actuating means so that the circular knife comes into contact with the shear bar of the lower knife.
- two guide rods are provided, as a result of which the cutting pressure that occurs is absorbed by the two guide rods in a torsion-resistant manner and the knife holder as a whole has a high degree of rigidity. Furthermore, the design of the knife holder according to the invention also distributes the load on the guides of the guide rods, as a result of which they are exposed to less wear. If the two guide rods are connected to a piston, it is achieved that the guide rods are actuated with the same pressure.
- the joint is arranged above the cutter head.
- the actuating means is arranged on the base body. It proves to be advantageous here that on the one hand the actuating means can be arranged in the base body, as a result of which the knife holder has a small overall width and the base body is designed as a unit with the actuating means. On the other hand, it is possible for the actuating means to be arranged outside of the base body, which ensures that training and adjustment work on the actuating means can be carried out more easily because of the easier accessibility by the operating personnel.
- the actuating means by a piston-cylinder unit is formed, which is connected to a pressure medium supply.
- the actuating means can be a pneumatic and / or hydraulic piston-cylinder unit which is connected to a pressure medium supply line.
- the setting of the circular knife can be realized, for example, in the form of a sequence control, the guide rod first being moved into an end position by pressure on a piston connected to the guide rod, and that the piston-cylinder unit of the actuating means is pressurized when the end position is reached, which moves the swivel arm so far that the circular knife comes to rest on the lower knife.
- the actuating means is assigned a return spring.
- the return spring can on the one hand hold the swivel arm in a basic position, i. H. in an undeflected position, and on the other hand it serves to push the swivel arm back into the basic position by means of the return spring when the circular knife is lifted from the lower knife after the piston-cylinder unit of the actuating means is no longer pressurized.
- the swivel arm is divided in the region of the joint, the swivel arm parts being releasably connected to one another.
- the assembly formed from the cutter head and the lower swivel arm part can be completely replaced, for example for maintenance and repair purposes.
- Due to the knife holder designed according to the invention it is also no longer necessary for the knife head to have a piston-cylinder unit as an adjusting element for lateral adjustment of the circular knife.
- the detachable connection of the swivel arm parts can take place, for example, via a guide with locking means, for example a dovetail guide. It is also possible for the swivel arm parts to be connected to one another. be screwed, with all connection options ensuring a play-free connection of the swivel arm parts.
- the cutter head has a bearing bracket which is detachably connected to the swivel arm.
- a bearing bracket which is detachably connected to the swivel arm.
- the lateral adjustment of the circular knife against the lower knife is achieved by the knife holder designed according to the invention, it is not necessary, as was previously the case, to design the knife head with a piston-cylinder unit as an adjusting element.
- the connection can be made, for example, via a guide with locking means, for example a dovetail guide, or it is also possible for the bearing bracket to be screwed to the swivel arm.
- FIG. 1 is a partially sectioned side view of a first embodiment of a knife holder for circular knives
- FIG. 2 shows a partially sectioned front view of a first embodiment of the knife holder according to FIG. 1,
- FIG. 3 shows a partially sectioned side view of a further embodiment of a knife holder for circular knives
- Fig. 4 is a partially sectioned front view of a double knife head.
- FIG. 1 shows a partially sectioned side view of a first embodiment of a knife holder 1 for a circular knife 2 with a base body 3, which is attached to a knife bar (not shown) by means of gill means and a Fastening groove 4 can be determined.
- the base body 3 has two parallel guides 5 with guide bushes 6, 5 guide rods 7.1, 7.2 being slidably mounted in the guides.
- the base body 3 is connected to a housing 8 which is designed as a cylinder and in which a piston unit 9 connected to the guide rods 7.1, 7.2 is displaceably guided, the housing 8 being closed off with a cover 10.
- the cover 10 has a connection element 11 for a pressure medium line 12.1, by means of which pressure medium is introduced into a pressure distribution chamber 13, so that the piston 9 executes a lowering movement in the direction of the arrow X, as a result of which the circular knife 2 is immersed in a groove 14 of a lower knife 15.
- a compression spring 16 is arranged, which serves to move a cutter head 17 in the depressurized state in the direction of the arrow Y and to hold it in the rest position.
- the cutter head 17 with the rotatably mounted circular knife 2 is arranged on a cross member 18, the cross member 18 being pivotally mounted on an articulated rod 19 which is mounted in the ends of the guide rods 7.1, 7.2.
- a pivot arm 30 is mounted on the articulated rod 19 and is formed by a cross member 18 and an actuating arm 20, the cutter head 17 being arranged at one end of the cross member 18.
- the actuating means 21 shown in dashed lines engages at one end of the actuating arm 20, wherein a deflection of the actuating arm 20 by the actuating means 21 causes a deflection of the cutter head 17 in the opposite direction.
- FIG. 2 shows a partially sectioned front view of a first embodiment of the knife holder according to FIG. 1 with a base body 3, in which guide rods 7.1, 7.2, not shown, are slidably mounted, at the end of which the articulated rod 19 is mounted.
- the cutter head 17 with the rotatably mounted circular knife 2 has a bearing bracket 26 on which a bearing 27 is arranged and which is detachably connected to the cross member 18 by means of a dovetail guide 28.
- the cutter head 17 is inserted with the bearing bracket 26 into the dovetail guide. and can then be fixed using screws, for example.
- Fig. 3 shows a partially sectioned side view of a modified embodiment according to FIG. 1, wherein the cross member 18, on which the cutter head 17 is arranged, is mounted on the articulated rod 19 connected to the guide rods 7.1, 7.2.
- the actuating arm 20, which is connected to the crossmember 18, is arranged outside the base body 3 and can be pivoted via an actuation means 21 arranged on the outside of the base body 3.
- the crossmember 18 is deflected and thus the circular knife 2 is brought into contact with the groove flank 25 (not shown).
- Fig. 4 shows a partially sectioned front view of a further embodiment of the knife holder, wherein an articulated rod 19 is connected to the guide rods, not shown, similar to the embodiment in Fig. 1, on which two pivot arms 30.1, 30.2 are pivotally mounted relative to each other, each having a cutter head 17.1 , 17.2.
- the swivel arms 30.1, 30.2 are formed from an upper swivel arm part 31.1, 31.2 and a lower swivel arm part 32.1, 32.2, the swivel arm parts 31, 32 being releasably connected to one another without play.
- the connection of the swivel arm parts 31, 32 takes place below the joint 19 via a guide 33.1, 33.2, which is dovetail-shaped.
- the swivel arm parts 31, 32 are additionally fixed in the area of the dovetail guide 33 by means of locking means (not shown in more detail).
