BLADE HOLDER WITH ADJUSTING SLIDE

Abstract

A blade holder (1) for a longitudinal cutting machine includes a rotatably mounted blade head (3) for holding a circular blade (4) and at least one locking device (2). At least one actuator actuates an element of the blade holder (1), and a moveably mounted adjusting slide (5) positions the blade head (3) on the longitudinal cutting machine. The adjusting slide (5) for positioning of the blade head (3) is moveable from a starting position to a positioning point. With the blade holder, materials can be cut perfectly with high precision. In particular, materials such as tissue, non-woven materials, paper, OLED film, displays, battery film, lithium batteries, aluminum, copper film, anodes, and cathodes can be cut.

Claims

1. A blade holder (1) for a longitudinal cutting machine, comprising: a rotatably mounted blade head (3) for holding a circular blade (4); at least one locking device; at least one actuator for actuation of an element of the blade holder (1); and a movably mounted adjusting slide (5) for positioning the blade head (3) relative to the longitudinal cutting machine, wherein the adjusting slide (5) is moveable for positioning of the blade head (3) from a starting position to a positioning point, and wherein the adjusting slide (5) is coupled with a locking device, the locking device being configured to prevent actuation of the blade holder (1) as soon as the adjusting slide (5) is moved out from the starting position.

2. The blade holder (1) according to claim 1, wherein locking takes place mechanically when the adjusting slide (5) is moved out of the starting position.

3. The blade holder (1) according to claim 1, wherein locking takes place electrically and/or electronically when the adjusting slide (5) is moved out of the starting position.

4. The blade holder (1) according to claim 1, wherein locking takes place pneumatically when the adjusting slide (5) is moved out of the starting position.

5. The blade holder (1) according to claim 1, further comprising a switch (2), wherein the switch is configured to be activated by the adjusting slide (5) as soon as the adjusting slide (5) is moved out from the starting position, wherein the switch (2) in an activated state triggers locking.

6. The blade holder (1) according to claim 1, wherein locking interrupts an energy supply to at least one actuator of the blade holder (1).

7. The blade holder (1) according to claim 1, wherein the blade holder (3) is linearly adjustable in the direction of an axis of rotation of the blade holder (3).

8. The blade holder (1) according to claim 1, wherein the blade head (3) is adjustable transverse to an axis of rotation of the blade head (3).

9. The blade holder (1) according to claim 1, wherein the adjusting slide (5) is pivotably mounted.

10. A longitudinal cutting machine with a plurality of blade holders (1) according to claim 1, wherein the blade holders (1) are held as upper blades on a continuous traverse of the longitudinal cutting machine and each of the multiple blade holders (1) is associated with at least one lower blade.

11. The longitudinal cutting machine according to claim 10, wherein actuation of the entire cutting machine is prevented when the adjusting slide (5) of an individual blade holder (1) is moved out of the starting position.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The invention and the technical field are described next with reference to the figures. In the figures:

[0023] FIG. 1 shows a perspective view of a blade holder with an adjusting slide in a starting position;

[0024] FIG. 2 shows a side view of the blade holder according to FIG. 1;

[0025] FIG. 3 shows a perspective view of the blade holder with the adjusting slide pivoted out from the starting position; and

[0026] FIG. 4 shows a side view of the blade holder according to FIG. 3.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] The blade holder 1 shown in the figures includes a locking device (not shown), with which the blade holder 1 is displaceable along a traverse (not shown) of a longitudinal cutting machine and which can be fixed to this traverse.

[0028] The blade holder 1 also includes a blade head 3, to which a circular blade 4 is attached. The blade head can be lowered by means of an actuator.

[0029] The blade holder 1 also includes an adjusting slide 5 for positioning the blade holder 1 on the traverse. In this connection, the adjusting slide 5 has a contact element 6, whose relative vertical position corresponds with the position of the cutting edge of the circular blade 4. The starting position of the adjusting slide 5 is shown in FIGS. 1 and 2.

[0030] For positioning of the blade holder 1 on the traverse, the adjusting slide 5 is pivoted downward, so that the contact element 6 can be brought into contact with a cutting edge of a lower blade (not shown) (see FIGS. 3 and 4). As soon as the blade holder 1 is positioned on the transverse by contact of the contact element 6 on the cutting edge of the lower blade, it can be fixed by means of a locking device. For the cutting process, the blade head 5 is lowered by means of the actuator.

[0031] Locking is now provided, which is activated by means of a switch 2 as soon as the adjusting slide 5 is pivoted out of the starting position shown in the figures. The switch 2 is thereby coupled with the actuator, such that lowering of the blade head 3 with an activated switch 2 is prevented.

[0032] The features of the subject matter of this invention set forth in the above description, the patent claims, the abstract and the drawings can be used individually and in any desired combination for the realization of the invention in its various embodiments.

[0033] The present invention is, of course, in no way restricted to the specific disclosure of the specification and drawings, but also encompasses any modifications within the scope of the appended claims.
