Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slitter machine KpL that cuts wide roll paper and other sheet-like materials into narrow widths, an O slitter machine that relates to a device that moves and fixes a cutting blade to a desired position, and particularly a slitter machine that cuts wide roll paper and other sheet-like materials into narrow widths. For cutting paper and resin films, there are two types of blades: a receiving blade with a large number of blades arranged at regular intervals without gaps, and a cutting blade that is fitted on the shaft and fixed at a position facing any receiving blade. As shown in FIG. 1, the wide roll material (3) is sequentially rewound, and the roller CB)
(B) while passing between the cutting blade (1) and the receiving blade f21 to cut it into a narrow width, and then cut it into a narrow width again with the axis FC+
There is one that is designed to be rolled up.

In the past, when changing the cutting width of roll paper, etc., the cutting blades had to be manually operated one by one.
This was troublesome as there was a risk of injury due to the sharp cutting blade.

In addition, some machines have a cutting blade attached to a movable table that can be moved independently, but with such machines, the moving parts are large-scale, making it difficult to maintain accuracy, and the cutting blade is difficult to maintain due to the size of the moving parts. The disadvantage was that the arrangement of the blades was restricted and they could not be arranged at close intervals.

In view of these points, the present invention mechanically moves only the cutting blade, which was previously done by hand, without impairing the functions of conventional machines, and allows it to be firmly placed in the desired position. We devised a moving device that can be fixed in place.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cutting blade moving device for a slick machine according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a side view schematically showing the slitter machine of the present invention;
FIG. 2 is a front view schematically showing the cutting blade, the receiving blade, and the cutting blade moving device.

The cutting blade +11 is attached to a cutting blade holder (3), which is fixed at an arbitrary position on the cutting blade shaft (4). for example,
As shown in Figure 3, the cutting blade (1) is fixed and the cutting blade shaft (
An eccentric groove (6) is carved on the inner circumferential surface of the cylindrical holug main body (5) that is loosely fitted into the key (7) that can be fitted into the large diameter portion of the eccentric groove (6). is held on the cutting blade shaft (4). By rotating the main body (5), the key (7) is bitten into the eccentric groove and can be fixed at any position on the cutting blade shaft. In Fig. 3, (8) is a narrower groove within the eccentric groove (6);
A spring (9) that engages with the key (7) is located inside to hold the key (7) on the cutting blade shaft (4).

On the other hand, a large number of receiving blades (2) are arranged (for example, at 5% intervals) on a receiving blade axis (lO) fixed parallel to the cutting blade axis (4), and cutting blade f11 corresponds to any receiving blade. It is possible.

A cutting blade shaft (4) supporting the cutting blade (1) is supported by an arm (11), and the base end of this arm O+1 is fixed to a swing shaft f121. Therefore the oscillating motor Its)
By rotating the swing shaft 112), the cutting blade shaft (
4), and when moving the cutting blade fil, use the receiving blade (2).
) so that it is possible to break the bond with (Two-dot chain line in Fig. 2) In addition to these, a cutting blade moving means that moves parallel to the cutting blade axis (4) is provided.

This moving means has both ends with arms +141 and Q41.
A spline shaft row supported by and arranged parallel to the cutting blade axis, a feed screw (Iφ and a cutting blade holder (3)
It consists of a gripping device Qη that grips the.

The gripping device aη is capable of sliding along the spline shaft 0υ, while the gripping device aη is movable along the spline shaft (10).
This allows the gripping device Qη to be tilted up and down.

The gripping device αη is screwed onto a feed screw f+61 rotated by a motor (19), and can be moved left and right.

The gripping device that grips the cutting blade holder can have any structure as long as it can grip the cutting blade holder so that it does not rotate. It can be provided with two gripping means for gripping both sides.

That is, the gripping device shown in FIG. 4 has a spline shaft f16).
A pair of pawls (2) that move in the axial direction of the spline shaft by means of a cylinder round and grip both end surfaces of the cutting blade holder (3) are attached to the main body of the gripping part fitted with the feed screw (1φ).
, @, and a pair of claws (2) and (c) which are fixed to the grip main body □□□, are opened and closed vertically by a cylinder (2), and grip the circumferential side of the cutting blade holder. . In the drawing (261 is the guide shaft of the claw).

A gear is loosely fitted to the swing shaft 1121 at the left end in FIG. This gear is a clutch
K engages with the gear (c) which is engaged with and disengaged from the cutting blade shaft (4), and is rotated in one direction by the cylinder 4, thereby rotating the cutting blade shaft (4) in a fixed direction. And the cutting blade shaft (4)
This is for releasing the fixation of the cutting blade holder held by the gripping device αη by rotating the holding device αη.

On the other hand, the swing shaft (the right end of 121 has a clutch) engages the gear 02, which is engaged and disengaged from the cutting blade shaft (4), and is rotated by the cylinder (to) in the opposite direction to the above case. The gear is loosely fitted. This serves to tighten the cutting blade holder.

Next, the operation of the slick machine having the above structure will be explained.

Under normal operating conditions, as shown in Figures 1 and 2 (solid lines), the material to be cut, such as roll paper, passes between the cutting blade i11 and the dream blade (2), cutting it into a narrow width. It has been cut.

When changing the cutting width of roll paper, etc., first rotate the swing shaft (121) using the swing motor a, and turn the arm (
Raise the cutting blade shaft (4) supported by the cutting blade fl) and the receiving blade (2
) is solved.

At this time, the cutting blade holder (3
). [Figure 5 (a)] Then, the motor (181) of the spline shaft (151) is driven to lower the gripping device 0η located at the dotted line position in Figure 1 to the solid line position,
Align it with the position of the rising cutting blade axis. [Figure 5 (b)] Next, operate the cylinder of the gripping device 07), and use the claws (c) and (a) to grip the circumferential side of the cutting blade holder (3) and hold it so that it does not rotate. . [Figure 5 (c)] In this state, operate the clutch (c) to connect the cutting blade shaft (4) and gear □□□, then operate the cylinder (to) and rotate the gear to perform cutting. The blade shaft (4) rotates, causing a relative rotational movement between the cutting blade holder (3) held by the claws (8) and (a) of the gripping device 0η and the cutting blade shaft, and the cutting blade The holder is untightened. [See Figure 5]
)] At this time, the cutting blade holder (3) can freely slide along the cutting blade axis.

Next, the clamping of the claws (2) is released, and the cylinder circle of the gripping device 0η is activated to clamp both ends of the cutting blade holder (3) with the claws (3).

[Fig. 5 (e)] While holding the cutting blade holder (3) between the claws, drive the feed screw 0φ by the motor (I) and press the gripping device 071.
Move the cutting blade holder (
3) slides on the cutting blade shaft (4) and moves together with the gripping device O'71. [Figure 5 (f)] Cutting blade holder (3)
After moving the blade to the desired position, the cylinder reactivates the claws (24) of the gripping device aη, and the cutting blade holder (3) is moved to the desired position.
Hold it firmly so that it does not rotate. [Figure 5 (G)] After that, the clutch (31) is operated to connect the gear 02 and the cutting blade shaft (4), and the gear is rotated around the cylinder and engaged with it. The cutting blade shaft (4) is rotated through the gear (4) in the opposite direction to that shown in Fig. 5, and the cutting blade holder is rotated through the cutting blade shaft (4).
) on top to secure it. [Example in Figure 5] Cutting blade holder (
When the tightening of 3) is completed, release the clamping of the claws (4 and 4), and drive the spline shaft (1υ motor) to raise the gripping device (171 [Figure 5 (S)]).
The gripping device θ is driven by driving the motor 0 (2) of the feed screw αυ.
Return η to the reference position. [FIG. 5(B)] By repeating the above operation as many times as necessary for the cutting blades, the entire arrangement of the cutting blades is completed. When the arrangement of the cutting blade is completed, the swing motor Oj is driven to rotate the arm (11), and the cutting blade shaft (4) supported by this is moved as shown by the solid line in Figure 2. , return to the working position where the cutting blade and receiving blade are engaged.

At this time, the clutch (0I) is disengaged, and the cutting blade shaft (4) is driven to rotate by, for example, another power mechanism via the gears (TO), (TO).

In the illustrated embodiment, a feed screw α turret is used as a moving means for the gripping device 071, but it may be indexed from side to side using a chain or wire, for example.

Also, gripping device a? 1 is designed to grip the cutting blade holder in two places, one on both ends and one on the circumference, but if it can be used to securely grip the cutting blade holder in a predetermined position and prevent it from rotating, 1 is suitable. There may be two gripping means.

Furthermore, in order to relatively rotate the cutting blade holder fixed by the gripping device and the cutting blade shaft to tighten and release the cutting blade holder, a release tool is attached to the left end of the swing shaft and the cutting blade shaft. Although a tightening mechanism is provided separately at the right end, this mechanism may be replaced by a single rotating mechanism. In that case, there is a possibility that the gripping device, the cutting blade holder, or the clutch may slip, and it would be desirable to provide a means to detect whether the gripping device is securely tightened or released, and to respond accordingly.

Note that the present invention may be applied to a cutting blade holder of a type that is fixed by a relative rotation operation with respect to the cutting blade shaft. For example, Patent No. 1170074 (Japanese Patent Publication No. 57-5
No. 5660), a locking pawl that can slide along a groove cut in the axial direction of the cutting blade shaft is built into the cutting blade holder, and this is biased in the rotational direction by a spring to perform cutting. It can also be applied to a device in which the locking pawl is locked in a large number of circumferential grooves carved at small intervals on the blade axis.

In this case, as soon as the gripping device is released, the cutting blade holder is fixed by the action of the spring, so the tightening mechanism corresponds to the clutch (31) to the cylinder (to) in the previously illustrated embodiment. becomes unnecessary.

According to the cutting blade moving device for a slick machine of the present invention, the cutting blade can be moved without directly touching the cutting blade, which is extremely safe and efficient. Since manual work is eliminated, the positioning of the cutting blade can be performed automatically, accurately, and quickly by controlling a series of operations in a program.
