Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet end face aligning apparatus for simultaneously cutting laminated sheets.

[0002]

2. Description of the Related Art The following technique is known as a conventional technique relating to a sheet stack aligning device.

(A) JP-B-44-27249 (B) JP-B-44-9061 (C) JP-B-54-24790 (D) JP-A-57-141355 (E) JP-A 58-193851 gazette (f) JP-A-1-203131 gazette Among these, (b), (c), (d) and (e) are four cases in which the seat is curling in order to invert the seat almost vertically, There is also a problem that when the sheets are inverted, the sheets are bent and it becomes impossible to align them.

Further, in (a) and (f), when the laminated sheets are of a flat type and the number of laminated sheets is large, the separating effect of the sheets by air blow is limited to the upper layer portion, and air is introduced to the lower layer sheet. There was a problem that the sheets could not be sorted out without the loosening effect. Further, for example, if the sheet laminates are subjected to corner round processing without being aligned, the sheet photosensitive material film may not be processed into a bad shape, which may hinder the loading and conveying of the sheet photosensitive material film to the processing device.

[0005]

If the sheet is inverted almost vertically, the curl or the like is emphasized and the sheet is bent and turned over, so that the end faces are not aligned and the alignment becomes extremely poor.

Further, when a large number of laminated sheets are laid flat, even if the laminated sheets are mechanically vibrated or rocked, the sheets are aligned only in the upper layer portion and in the lower layer portion. It is the current situation that the roles of are not effective and they cannot be arranged.

In such a state, the cutting quality of the sheet and the corner cut of the corner are inferior, and the transportability and the storability are also deteriorated.

An object of the present invention is to eliminate such problems and to provide a stable aligning device to remarkably improve the cutting quality of the sheet laminate.

[0009]

The object of the present invention is to shake an end face of a laminated body in a device for vibrating and aligning a sheet laminated body in which a plurality of sheets are stacked on the inclined base. This is achieved by an aligning device for a sheet laminated body, which is provided with an air blowing mechanism that blows air while moving.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is a side sectional view of FIG. 1, FIG. 2 which is an AA view in FIG. 1, a front view of a nozzle rocking portion of FIG. 3, and a side view thereof. This will be described with reference to FIG. 5, which is a side view of another embodiment of the nozzle rocking portion.

The inclined base 102 on which the sheet laminated body 141 is placed is fixed on the frame 101 at an inclination of about 45 ° with respect to the horizontal plane, and serves as an air table.

The inclined base 102 is provided with fixed guides 107 at two positions on each side so that when the sheet stack 141 is placed, two adjacent sides of the sheet stack 141 serve as a reference. Has been.

On a frame 101, guide rails 106 are provided in parallel at four places, slide blocks 105 are fitted, the slide blocks 105 are fixed to a vibrating table 104, and each side of the sheet laminated body 141 is attached to the vibrating table 104. The claws 103 are fixedly attached so as to correspond to two places. Shaking table 104
Is provided with a cam follower 124, and the vibrating table 104 is reciprocated by a contactor 123 at the tip of an arm 122 that is swung by a cam (not shown) around a support shaft 121 that contacts the cam follower. That is, the forward movement is performed by the arm being lifted by the cam, and the backward movement is performed by the elastic body 13 by the gravity and the spring 133 fitted on the guide pin 132.
It is done by being pushed back through 1. Two such vibrating tables 104 are provided so as to correspond to two adjacent sides of the sheet laminate 141.

The tilting table 102 is provided with a notch 109 so that the claw 103 of the vibrating table 104 can sufficiently contact the lowest sheet of the sheet stack.

Even if such a vibration device is attached, the alignment is not perfect. That is, if the sheet laminates are not separated one by one, the frictional force between the sheets is strongly deviated, and the sheets remain detached, and the alignment of the entire sheet laminates cannot be expected.

Therefore, an air nozzle for sorting is provided so as to blow air on the side surface of the sheet laminated body, and the air nozzle 135 is provided so as to swing from the upper layer to the lower layer of the sheet laminated body. The air nozzle 135 is a claw 103 on the vibrating table.
Correspond to the opposite sides of the contacting sides.

By driving the vibrating table 104 while swinging the air nozzle 135 from the upper layer to the lower layer, the sheet loosening effect and the sheet interleaving effect are mutually interpolated, so that accurate alignment can be achieved at once. In such a state, the sheet laminated body 141 is pressed from the upper layer portion and clamped so that the corners of the sheet laminated body 141 are simultaneously rounded so that the corners can be accurately and accurately rounded.

As shown in the front view of FIG. 3 and the side view of FIG. 4, the nozzle oscillating portion is the rotary shaft 1 of the rotary actuator 137.
An air nozzle 135 having an air pipe 139 is attached to the other end of an arm 136, one end of which is fixed to 37A, to move between the upper and lower layers of the sheet stack.

FIG. 5 is a side view of another embodiment,
Instead of the rotary actuator 137, the air nozzle 135 joined to the air tube 139 is attached to the tip of the plunger rod 138A of the air cylinder 138, and the plunger rod is moved up and down to reciprocate between the upper layer and the lower layer for uniform handling. It is carried out.

[0020]

According to the present invention, the sheet laminates can be aligned accurately in a short time, and the cutting work and the corner cutting work after the alignment can be easily and accurately performed, thereby improving the productivity and the cutting work. The quality has improved dramatically.
