Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stack placement position correcting device in a feeder that supplies a stack of sheet materials to a press machine.

Conventionally, this type of stack feeder has an endless belt or chain shape, and the stacks are placed on a pallet and transported onto the stack feeder using a forklift or the like, and then transported and fed toward a press machine. It is known that it was made to look like this.

On the other hand, when transporting a stack to a press machine, it is necessary to position the stack in a direction perpendicular to the transport direction. If the stacks are placed in the same position, the stacks will be misaligned in the direction perpendicular to the transport direction.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to provide a stack placement position correction device for a stack feeder that can correct the position of the stack in a direction perpendicular to the conveying direction to the correct position. It is.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of the stack feeder A, in which a chain 3 is wound around sprockets 2 and 2' provided at both ends of a frame 1, and one sprocket 2 is rotated by a drive source (not shown). It is configured.

As shown in FIG. 3, the chain 3 has unit links 4 pivotally connected by pins 5. Blocks 6 are provided in the unit chain 4 at predetermined intervals, and these blocks 6 connect stacks B to each other. The stack B is conveyed and supplied to a press machine (not shown) by contacting the pallet 7 placed thereon.

At the stack placement (loading) position in the frame 1, a pair of back gauges 8.8 which also serve as stoppers for preventing load collapse are fixedly installed, and at a position opposite to the pair of back gauges 8.8, a stack placement position correction device C is installed. is provided.

The stack placement position correcting device C is constructed as follows.

Guide rail 10 perpendicular to the stack conveyance direction
A main body 11 is slidably provided via rollers 12, and a movable part 1 of an evacuation cylinder 13 is attached to the main body 11.
3a, and the lock pin 15 is connected to the guide rail 1 using the lock cylinder 14 provided on the main body 11.
It is designed so that it can be fitted into first and second lock holes 16 ₁ and 16 ₂ formed at 0.0.

The main body 11 includes a pair of moving bodies 17 ₁ , 17 ₂
is provided movably via the feed screw rod 18,
Each moving body 17 has a holding plate (front gauge) 1.
9 is the guide hole 20. It is movably mounted via a guide rod 21, and a correction cylinder 22 is provided across the holding plate 19 and the movable body 17.

After placing the stack B together with the pallet 7 on the chain 3, the evacuation cylinder 13 moves the main body 11 to a corrected position close to the chain 3, and the lock cylinder 14 moves the lock pin 1 to the correct position.
5 into the first lock hole ₁₆₁ to fix the main body 11 in that position.

Thereafter, the pair of presser plates 19 are moved toward the stack B by the pair of correction cylinders 22, and the stack B is moved to correct the placement position.

At this time, as shown in FIG.
₁ , 17 _{and 2} are moved to predetermined positions depending on the shape and size of the stack B, and when the pair of correction cylinders 22 are stroked to the stroke end, the stack B is moved to a predetermined position by the pair of holding plates 19 and 19. The position is adjusted accordingly.

After the position correction is completed, lock cylinder 1 is
4, pull out the lock pin 15 from the first lock hole ₁₆₁ , move the main body 11 along the guide rail 10 using the retracting cylinder 13 to the retracted position, and then use the lock cylinder 14 again to insert the lock pin 15 into the second lock hole _162. and lock it in place.

As a result, the pair of presser plates 19 are separated from the stack B, and there is no problem in transporting the stack B.

The present invention is as described above, and the evacuation cylinder 13
At the same time, the main body 11 is moved toward the stack feeder side, and each holding plate 19 is moved forward toward the back gauge 8 by the correction cylinder 22, so that the pallet 7 is
By pressing the upper stack B against the back gauge 8 using the presser plate 19, the position of the stack B in the direction orthogonal to the conveyance direction can be accurately corrected to a predetermined position.

Furthermore, since each movable body can move independently relative to the main body 11, the position of each presser plate 19 can be changed depending on the shape and size of the stack B before the position is corrected by the correction cylinder 22. Even if the stack B has an irregular shape, the position of the stack B in the direction orthogonal to the conveyance direction can be accurately corrected to a predetermined position by moving the holding plate 19 forward by each correction cylinder 22.

Further, since the main body 11 can be moved in the direction away from the stack feeder by the evacuation cylinder 13 to the evacuation position, each presser plate 19 can be separated from the stack B by setting the main body 11 to the evacuation position. Therefore, when the positions of the respective presser plates 19 are varied by more than the reciprocating stroke of the correction cylinder 22, the presser plate 19 located on the rear side in the conveyance direction can be prevented from interfering with the stack B when the stack B is conveyed.

In other words, the position of each moving body is set in advance according to the shape and size of the stack, and the position of each moving body is set in advance according to the shape and size of the stack.
The presser plate 19 is reciprocated to correct the position and the correction is completed, but the reciprocating stroke of the presser plate 19 is short, and if the difference in position of the presser plate is larger than this stroke, the correction cylinder 22 is used to correct the position of the presser plate 19. Even if it moves back and separates from stack B, one presser plate will still be in a position where it will interfere with stack B.
If the stack B is conveyed in this state, the stack B and one of the presser plates will interfere and the position of the stack B will shift, but as described above, move the main body 11 in the direction away from the stack feeder to the evacuation position. This makes it possible to separate each presser plate from the stack B and prevent them from interfering with each other during conveyance.

Furthermore, by fitting the lock pin 15 into either the first lock hole ₁₆₁ or the second lock hole ₁₆₂ in the lock cylinder 14, the main body 11 can be fixed at a position moved toward the stack feeder side, and the correction cylinder 22
This prevents the main body 11 from moving when moving the presser plate toward the back gauge 8 to correct the position of the stack B, making it possible to reliably correct the position. The main body 11 can be fixed in the retracted position by fitting into either one of the lock holes ₁ and ₂ , and the main body 11 can be moved to the stack feeder side when transporting the stack B. This can ultimately prevent the holding plate from interfering with the stack B due to movement.
