[0001]

BACKGROUND OF THE INVENTION The present invention relates to a positioning device for positioning a work conveyed by a conveyor.

[0002]

2. Description of the Related Art Conventionally, in a positioning device of this type, when positioning is performed in a direction perpendicular to a flow direction of a conveyor, positioning is performed with reference to a positioning member extending in the flow direction of the conveyor. Further, when there are a plurality of reference positions, a device such as a positioning unit is required.

[0003]

However, there has been a problem that positioning by a positioning unit or the like requires complicated control and is expensive. Therefore, an object of the present invention is to provide a positioning device that can set a plurality of reference positions with a simple structure.

[0004]

According to the positioning device of the present invention, a pair of opposing positioning members extending in the flow direction of the conveyor are driven by pistons and cylinders so as to be able to advance and retreat in a direction perpendicular to the flow direction. And one of
Stopper pin arranged base outside the position-decided Me member
And the stopper pin is connected to the one positioning member.
Is moved up and down the path where the
The member can be prevented from retreating .

[0005]

[Function] One piston / cylinder is contracted, and the flowing work is moved toward one positioning member to the other piston.
By pressing in cylinder can first positioning relative to the one of the positioning member. Also the other fixie
And a down cylinder is contracted, by pressing the flowed workpiece on one of the piston and cylinder to the other of the positioning member side, it is a second positioning relative to the other positioning member. Further, after one piston / cylinder is extended, the stopper pin is protruded, and the flowing work is pushed toward one positioning member by the other piston / cylinder. In this case, the third positioning can be performed based on the one positioning member at this position without the one positioning member abutting on the stopper pin and retreating further.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A positioning device according to an embodiment of the present invention will be described with reference to FIGS. This positioning device is attached to a conveyor 1 that conveys an object such as a panel to an apparatus such as an edge pasting machine. That is, a pair of pistons
Cylinders 2 and 3 are provided. These piston-cylinder 2,3 diameter, stroke differ, one piston
The pressing force of the emission cylinder 2 and the other piston-cylinder 3
Is set smaller than the pressing force. Positioning members 4 and 5 are attached to the distal ends of the pistons 2 and 3, and are integrally fixed to bases 6 and 7 disposed outside the positioning members 4 and 5 . The positioning members 4 and 5
They extend in the flow direction of the conveyor 1 and face each other.
A belt 13 driven by a motor 12 is attached to the opposing surface, and guide rods 14 project from the back surface of the opposing surface. In FIG. 3, the guide rod 14 is omitted.

[0007] One of the pistons 6
A base 6 to which the cylinder 2 is fixed is connected to a moving column 20 of the edging machine, and a guide 9 guided by a linear way 8.
Is fixed. The linear way 8 has a rail shape extending in a direction perpendicular to the flow direction of the conveyor 1. The base 6 further supports a vertically movable stopper pin 10 via an inverted L-shaped support portion 11. The stopper pin 10 is a path through which one of the positioning members 4 advances and retreats.
And lifting the, during descent, protruding between the positioning member 4 and the base 6. Holes 15 for guiding the guide rods 14 of the positioning member 4 are formed in the base 6 .

The base 7 to which the other piston / cylinder 3 is fixed is screwed to a threaded rod 16 in the same direction as the linear way 8. The screw rod 16 is operated by an operation handle 17. 1
A lock handle 8 fixes the rotation of the threaded bar 16.
The conveyor 1 is driven by a motor 19. Next, the operation of the positioning device will be described. In advance,
The position of the base 9 is adjusted by sliding the guide 9, and the position of the base 7 is adjusted by operating the operation handle 17. In this state, the work is conveyed by the conveyor 1 to the edge applying machine via the positioning device. Also,
4 to 6, dashed lines C and D indicate the positioning
4 shows the position when the female members 4 and 5 are retracted to the maximum.

Here, when performing the first positioning based on one positioning member 4, as shown in FIG. 4, one piston / cylinder 2 is contracted , and one positioning is performed.
The member 4 is fixed at the position C. Then, the flowing work is pushed by the positioning member 5 toward the one positioning member 4 by extending the other piston / cylinder 3 and positioned. Conversely, when performing the second positioning based on the other positioning member 5, as shown in FIG. 5, the other piston / cylinder 3 is contracted, and the other piston / cylinder 3 is contracted .
The positioning member 5 is fixed at the position D. Then, the workpiece that has flowed is extended by one of the pistons / cylinders 2 so that the positioning piece 4 is used for the other positioning member 5.
Push to the side to position. Further, the work that has come into contact with the positioning members 4 and 5 is smoothly sent to the edge applying machine by driving the belt 13.

Further, in the case of performing the third positioning for passing the work through the edge pasting machine, the work is set so as to be located at the center as shown in FIG. In this case, first, one piston / cylinder 2 is extended to position the positioning member 4.
And then lower the stopper pin 10 to lower the base 6
And the positioning member 4 (FIG. 3) . afterwards,
The other piston / cylinder 3 is extended, and the work is pushed by the positioning member 5. At this time, since the other piston / cylinder 3 has a larger pressing force ,
The cylinder 2 is pushed back, and the positioning member 4 comes into contact with the stopper pin 10 and does not retreat any more. As a result, the workpiece is positioned near the center of the conveyor 1 and can be passed through the edge pasting machine. After the stopper pin 10 is lowered, one piston / cylinder 2 may be contracted to bring the positioning member 4 into contact with the stopper pin 10 and the other piston / cylinder 3 may push the work. According to this procedure, it is not necessary to change the pressing force of the piston / cylinder 2, 3.

In this embodiment, three types of positioning can be performed as described above. Moreover, the main configuration is two pistons
Cylinder 2 and 3 is because it is not inexpensive and simple configuration of stopper pin 10. In addition, since the guide 9 is elongated , the end of the base 6 remote from the guide 9 is A
It is difficult to swing in the direction. In addition, the moving column 20 of the rimping machine
As a result, since the linear way 8 is driven and assisted, swinging in the B direction is unlikely to occur even if the linear way 8 is uniaxial, but a configuration in which a plurality of linear ways 8 may be provided. Further, the positioning members 4 and 5 are moved in parallel to the bases 6 and 7 by the guide rods 14.

The positioning device can be applied to devices other than the edge pasting machine, such as a device for applying a decorative material for a panel.
The bases 6 and 7 are guided by the linear way 8 and the threaded bar 16, but may be guided by other means.

[0013]

According to the positioning device of the present invention, one of the pistons and cylinders is contracted, and the flowing work is extended by the other piston and cylinder toward one of the positioning members and pressed by the positioning member. Thereby, the first positioning based on one positioning member can be performed. Further, by contracting the other piston cylinder, the flowed workpiece by stretching one of the piston-cylinder to the other of the positioning member side by pressing its positioning member, first the basis of the other positioning member 2 Can be positioned. Further, after one piston / cylinder is extended, the stopper pin is protruded, and the flowing work is pushed toward one positioning member by the other piston / cylinder. In this case, the third positioning can be performed based on the one positioning member at this position without the one positioning member abutting on the stopper pin and retreating further. As described above, three types of positioning are possible, and since the configuration is simple such as two pistons / cylinders provided with positioning members and stopper pins, it can be provided at low cost.
