6, upper and lower support carts 7 and 8 are respectively arranged via guide pieces 9 and 10 so as to be movable in the width direction, and an upper support 12 having a top slitter 11 at the tip is mounted on the upper support cart 7 in height. A lower support tool 14 for supporting the bottom slitter 13 is placed on the lower support carriage 8 which is adjustable in position, and a drive motor 15 is attached to the upper support carriage 7 and rotated by the drive motor 15. The driven pinion 16 is meshed with a rack 17 extending in the longitudinal direction of the upper frame 3 (width direction of the paper 1), and the vertical support carriages 7 and 8 are extended by push rods 18 so that the vertical support carriage 7 is moved. Lock mechanism that can connect and release 8 and 19
Is provided to make the slitter 2 movable. still,
In the figure, reference numeral 20 denotes a guide roll for guiding the paper 1.

A plurality of sets of the slitters 2 are arranged in the width direction of the paper 1, and the push rod 18 of the lock mechanism 19 of each slitter 2 is extended to extend the pusher 18 while the paper 1 is not passed through.
7, 8 are integrally connected, each drive motor 15 is driven to adjust the distance between the slitters 2, and then the push rods 18 are contracted to allow the paper 1 to flow between the top slitters 11 and the bottom slitters 13. It is designed to be cut vertically to an appropriate width.
Regarding the slitter 2 which is not used, the upper support 12 is raised to allow the top slitter 11 to escape upward.

Further, in the type without the lock mechanism 19 (the paper is always left on the line), the drive motor 15, the pinion 16 and the rack 17 as the traveling mechanism are also required for the lower support carriage 8 of the bottom slitter 13. Become.

[Problems to be Solved by the Invention] However, in the slitter 2 as described above, it is necessary to provide the drive motor 15 for each unit, which has drawbacks that the weight increases and the cost also increases. Was there.

In view of the above situation, the present invention aims to provide a slitter moving device that can position a plurality of sets of slits with one driving device and that can reduce weight and cost.

[Means for Solving the Problems] The present invention provides a plurality of top slitter supporting carriages having top slitters so as to be movable along a top slitter frame extending in the paper width direction and a plurality of bottom slitters. In a moving device of the slitter, wherein the bottom slitter support carriage is movably arranged along the bottom slitter frame extending in the paper width direction, the support frames are installed at positions on both width ends of the paper. On the support frame,
Two rod-shaped members that are located opposite to the paper and extend in the paper width direction are slidably arranged in the paper width direction, and at least one ends of both rod-shaped members are connected to each other, and both rod-shaped members are connected to each other. An actuator for moving integrally in the paper width direction is provided, and the top slitter support carriage is provided with a clamp mechanism capable of gripping and releasing the rod body on the top slitter side, and the bottom slitter support carriage is provided with the paper. Is provided with a clamp mechanism capable of gripping and releasing the rod-shaped body on the bottom slitter side, and the support frame is positioned on either one of the front and back sides of the paper and extends in the paper width direction. Of the rod-shaped body is slidably arranged in the paper width direction, an actuator for moving the rod-shaped body in the paper width direction is connected to one end of the rod-shaped body, and is connected to the side where the rod-shaped body is arranged. A supporting mechanism for gripping and releasing the rod-shaped body is provided on either one of the top and bottom slitter supporting carriages, and the top and bottom slitter supporting carriages are provided on the top and bottom slitter supporting carriages. It is characterized in that a lock mechanism capable of connecting and releasing the support cart is provided.

[Operation] Therefore, when one actuator is driven, the two rod-shaped bodies connected to each other move in the paper width direction, and at that time, the two rod-shaped bodies are moved by the clamp mechanism of the support cart for the top slitter and the bottom slitter of each slitter. If you hold the
A pair of top slitter and bottom slitter can be positioned at the same time, and a plurality of sets of slitters can be positioned at the same time.

Also, in the case where only one rod-shaped body is provided, the top carriage and the bottom slitter support carriages are connected by the lock mechanism in a state where the paper is not passed through, and either the top slitter or the bottom slitter support carriage is connected. If a plurality of sets of slitters are simultaneously positioned by gripping the rod-shaped body by the crank mechanism and moving the rod-shaped body in the paper width direction by driving one actuator.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the present invention, in which the same reference numerals as in FIG. 3 denote the same parts.

Support frames 21 and 21 are installed at positions on both sides of the width of the paper 1, and the support frames 21 and 21 are positioned above and below the support frames 21 and 21 at the upper and lower positions of the paper 1 and extend in parallel with the width direction of the paper 1. The rod-shaped members 22, 23 are slidably inserted in the width direction of the paper 1 via bearings 24, 25, and both ends of the rod-shaped members 22, 23 are connected by plates 26, 27, respectively. In the center of the paper 1, the tip of a lot 29 of an actuator 28 such as a hydraulic cylinder arranged in the width direction of the paper 1 is pivotally mounted, and a position detector 42 for detecting the expansion / contraction amount of the actuator 28 is arranged. The rod-shaped members 22 and 23 can be integrally moved in the width direction of the paper 1 by the expansion and contraction drive of 28.

On the other hand, the upper and lower support carriages 7 and 8 of each slitter 2 are integrally formed with clamp mechanisms 30 and 31 capable of gripping and releasing the rod-shaped bodies 22 and 23, respectively. The clamp mechanisms 30 and 31 respectively extend arm portions 32 and 33 from the upper and lower support carriages 7 and 8, respectively, and the rod-shaped bodies 22 and 23 penetrate the tip portions of the arm portions 32 and 33 with a slight gap. While forming holes 34 and 35, slits 36 and 37 reaching from the tip of the arm portions 32 and 33 to the holes 34 and 35 are formed, and the rod-shaped bodies 22 and 23 are further provided at the tip portions of the arm portions 32 and 33.
Of the clamp cylinders 38, 39 extending in the radial direction of the rods 40, 41 of the clamp cylinders 38, 39.
The rods 40 and 41 are fixed to the ends of the arms 32 and 33 so that the rods 22 and 23 are gripped when the cylinders 38 and 39 contract, and are released when the cylinders 38 and 39 extend. There is.

 Next, the operation of the above embodiment will be described.

First, when the clamp cylinders 38 and 39 of the crank mechanisms 30 and 31 of each slitter 2 for which the position adjustment in the width direction is performed are contracted, the slits 36 and 37 are narrowed down, and the holes 34 and 35 are reduced. The gaps formed between the rods 34 and 35 and the rod-shaped members 22 and 23 disappear, and the rod-shaped members 22 and 23 are gripped by the clamp mechanisms 30 and 31.

In this state, when the actuator 28 is expanded and contracted, the rod-shaped members 22 and 23 move in the width direction of the paper 1, and only the slitter 2 holding the rod-shaped members 22 and 23 by the clamp mechanisms 30 and 31 has the rod-shaped members. It moves in the width direction of the paper 1 together with the bodies 22 and 23. At this time, the expansion / contraction amount of the actuator 28 is monitored by the position detector 42. When the expansion / contraction amount reaches a set value, the actuator 28 is stopped by the detection signal from the position detector 42, and the rod-shaped body 22 , 23 are held at that position, and the slitter 2 is positioned.

Further, when the movement amount of each slitter 2 for which the position adjustment is to be performed is different, the expansion / contraction amount of the actuator 28 is set in multiple stages, and each time the expansion / contraction amount reaches each set value, The actuator 28 is once stopped, only the clamp mechanisms 30 and 31 of the slitter 2 corresponding to the set value are released, and the actuator 28 is expanded and contracted again.
Hereinafter, the same operation may be repeated. Further, in this case, instead of the position detector 42, a position detector (not shown) is provided on any one of the upper and lower supporting carriages 7 and 8 of each slitter 2, and the one or several slitters 2 are provided. Each time the position detector provided in the slitter detects that the paper has reached a predetermined position in the width direction of the paper 1, a stop signal is issued to the actuator 28, and after the actuator 28 is stopped, the clamp of the slitter 2 is performed. It is also possible to release only the mechanisms 30 and 31 and drive the actuator 28 again, and thereafter repeat the same operation to arrange each slitter 2 at a predetermined position in the width direction of the paper 1.

On the other hand, in the above embodiment, since the lock mechanism 19 as shown in FIG. 3 of the upper and lower supporting carriages 7 and 8 is not necessary, the slitter 2 can be moved even when the paper 1 is still passed through the slitter 2. However, in the case of targeting only the batch type one, either one of the rod-shaped bodies 22 and 23 is omitted, and a clamp mechanism 30 or 31 for gripping the omitted rod-shaped bodies 22 or 23. Alternatively, the lock mechanism 19 as shown in FIG. 3 may be provided on the upper and lower support carts 7, 8.

In this way, the drive motor for each slitter 2 is different from the conventional one.
Since it is not necessary to provide 15, it is possible to reduce the weight of the entire device and reduce the cost.

The device for moving the slitter of the present invention is not limited to the above-described embodiment, and the top slitter 11 and the bottom slitter 13 are not limited to those arranged vertically but may be arranged horizontally or inclined. That can also be applied to
The clamp mechanisms 30 and 31 are always released, and instead of holding the rod-shaped bodies 22 and 23 only when the clamp cylinders 38 and 39 contract, the rod-shaped bodies 22 and 23 are always urged by elastic members such as springs.
Needless to say, various changes can be made without departing from the gist of the present invention, such that the clamp cylinders 38 and 39 can be released only when the clamp cylinders 38 and 39 are extended.

[Effects of the Invention] As described above, according to the moving device of the slitter of the present invention, it is possible to position a plurality of sets of slitters only by driving one actuator, and the control device is greatly simplified. Therefore, there is an excellent effect that the weight of the device can be reduced and the cost can be reduced.
