Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a positioning device for conveying sheet material.

Generally, when a sheet material cut to a predetermined size is transported from a stacker in which the sheet material is stored, through a washing machine, to a press machine, and then press-processed, the sheet material is accurately cut into the press machine. Since it is necessary to set the sheet material to a certain position, a device is used to position the sheet material after cleaning.

Conventionally, such a device is arranged at the lower front end of the inclined chute by pressing the rear end of sheet materials of various lengths carried along the inclined chute with a single claw member. The sheet material is positioned by pressing the front end of the sheet material against the stopper section, and the pressing operation by the claw member is usually performed by moving the claw member forward and backward with a cylinder. Depending on the length of the material, positioning may not be possible within the stroke range of the cylinder, and it is necessary to provide a separate adjustment mechanism for such cases.

The present invention has been developed in view of these points, and it is possible to position the sheet material with good workability without providing a special adjustment mechanism and regardless of the length of the sheet material carried along the inclined chute. It is an object of the present invention to provide a positioning device for conveying sheet material that can be used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a positioning device for conveying sheet materials A, which is used to transport sheet materials A of various lengths along an inclined chute 2 consisting of a pair of inclined members installed in parallel.
By pressing the rear end of the slanted chute 2, the stopper part 2a disposed at the front of the lower end of the inclined chute 2 can be opened.
Positioning is performed by pressing the front end against the

On the lower side of the inclined chute 2, upper and lower guide rails 3, 4 (guide members) are arranged along the inclined chute 2. The front and rear ends of the guide rails 3 and 4 are installed between fixing members 5 and 6 that are fixed to the inclined chute 2 so as to project downward.

Reference numeral 7 designates a movable member, which includes a support portion 7a that is long in the chute direction of the inclined chute 2, a front protrusion portion 7b that protrudes downward from the support portion 7a, and a rear protrusion portion 7c. Only the upper guide rail 3 of the guide rails 3 and 4 is inserted through the rear protrusion 7c, so that the movable member 7 is movably supported by the guide rails 3 and 4.

Reference numeral 8 denotes a claw member, which is swingably supported by the support portion 7a of the movable member 7 at a predetermined interval along the chute direction of the inclined chute 2.

Each pawl member 8 has a front portion 8 with respect to the pivot 8a.
The rear portion 8c is made heavier than the rear portion 8c, so that it is always biased to a locking position (see FIG. 1) where the rear end of the sheet material A can be pressed. That is, the claw member 8
is pivotally supported in a downwardly rearward direction, and its front end slightly protrudes from the upper surface 2a of the inclined chute 2. Therefore, when the sheet material A passes upward, the weight of the sheet material A (self-weight) causes the sheet material A to be held at a position (see the front claw member 8 in FIG. 2).
is swayed by.

Reference numeral 9 denotes a cylinder means, which includes an air cylinder 10 consisting of a piston rod 10a whose tip is connected and fixed to the lower end of the front protrusion 7b of the movable member 7, and a cylinder body 10b, and an engagement member 11 to which the base end of the cylinder body 10b is connected. It is composed of.
Guide rails 3 and 4 are slidably inserted through the engaging member 11.

A fixed stopper member 12 is fixed to the lower side of the inclined chute 2 so as to be able to come into contact with the engaging member 11, thereby regulating the lowering position of the movable member 7 on the guide rails 3 and 4. It's getting old.

Reference numeral 13 denotes a base, on which a fixed member 5 is rotatably supported by a support bracket 14 erected at the rear thereof, and an air cylinder 15 attached at the front thereof is connected to a tilting chute via a link mechanism 16. 2 is connected to the front. Thereby, by operating the air cylinder 15, the front portion of the inclined chute 2 can be rotated upward, and the inclined chute 2 can be brought into a substantially horizontal state.

With the above configuration, the sheet material A carried onto the inclined chute 2 moves downward along the inclined chute 2 due to its own weight, and the stopper part 2
abuttingly engages with a. In that case, when the sheet material A passes upward, the claw member 8 is rotated clockwise by the weight of the sheet material A, and reaches a position where it does not lock the sheet material A, and after passing, the claw member 8 is rotated counterclockwise due to the balance of the forces, and the front end becomes a locking position where the rear end of the sheet material A can be pressed.

Subsequently, when the air cylinder 10 is actuated to cause the piston rod 10a to protrude, the movable member 7 moves along the guide rails 3 and 4.
The claw member 8 engages with the carried sheet material A at its rear end.

Furthermore, when the piston rod 10a is projected in the air cylinder 10, the engagement between the engagement member 11 and the fixed stopper member 12 is released, and the engagement member 11 moves rearward (upward) along the guide rails 3, 4. However, the cylinder means 9 and the movable member 7 are pressed by their own weight.

By the pressing operation, the sheet material A is set at a predetermined position by the cooperative action of the stopper portion 2a and the claw member 8.

When the air cylinder 15 is operated to bring the inclined chute 2 into a substantially horizontal state, it can be accurately set at a fixed position for the next step by means of suction conveyance means (not shown).

Since the present invention is configured as described above, it has an excellent practical effect in that the sheet material can be positioned with good workability regardless of the length of the sheet material carried along the inclined chute.
