A frame body 21 is vertically connected to one end of the support rod 15 on the sorter 2 side,
A mounting table 8 is provided on the frame body 21 and protrudes toward the sorter 2 side.
A stop plate 22 that can slide on the upper part is provided, and a sleeve 17 is fitted near one end of the support rod 15, and the ram 12 is connected to a joint 18 that connects the sleeves 17. 21 and the sleeve 17, one end of the link 23 is pivotally fixed to the sleeve 17, and the other end of the link 23 is provided to protrude perpendicularly to the frame 21. 24, the ring body 25 is provided with a frame body 27 and a push plate 26 which overlap with the frame body 21 and the stop plate 22, and when the ram 12 is extended from the cylinder 11. , first, the stop plate 22 stops the flow of the conveyed object 7, and then,
A conveyed object alignment device characterized in that a push plate 26 pushes a plurality of conveyed objects 7 on a mounting table 8 to one side. It is composed of

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

1 is a front view, FIG. 2 is a rear view, FIG. 3 is a right side view, and FIGS. 4 and 5 are plan views.

1 is a conveyed object alignment device, 2 is a sorter, and 3 is a conveyance device. The conveyance object alignment device 1 is fixedly installed on a floor surface 5 at a side near a joint 4 between the sorter 2 and the conveyance device 3 with a predetermined distance therebetween. The conveying device 3 has a conveyor 6 consisting of a plurality of stages of belts or rollers, and each of these conveyors 6 carries articles 7 placed on its upper surface at regular intervals and conveys them. The sorter 2 consists of a frame erected on the floor 5 at the end of the conveyor 3, and a mounting table 8 in contact with each conveyor 6 is supported horizontally.

Therefore, the conveyed object alignment device 1 will be explained in detail.
Reference numeral 9 denotes a base, and the base 9 is made of angle material to form a box frame body, and a pedestal 10 is stretched on one side of its upper part. Reference numeral 11 denotes a cylinder, and the cylinder 11 is fixed to the pedestal 10. Reference numeral 12 denotes a ram, which engages with the cylinder 11 and has a connecting portion 13 connected to its protruding end. Reference numeral 14 denotes guide blocks, and the guide blocks 14 are fixed to the pedestal 10 in pairs. Reference numeral 15 denotes support rods which are fitted into the guide blocks 14 and are movable parallel to the ram 12. Reference numeral 16 denotes a stopper, and the stopper 16 is a ring body fitted onto the support rod 15, and is fixed to the support rod 15 by a pin 16a. 17 is a sleeve; the sleeve 17
consists of a cylindrical body fitted into the support rod 15. 1
Reference numeral 8 denotes a joint, and the joint 18 integrally connects the sleeve 17 and each connecting portion 13. 19 is a spring, and the spring 19 is attached to the sleeve 1.
The support rod 15 is fitted into the end of the support rod 15 protruding from the support rod 7 . Reference numeral 21 denotes a frame body, which is fixed perpendicularly to the ends of the support rods 15, and is made of an angle material or the like. Reference numeral 22 denotes a stop plate, and the stop plate 22 is made of a plate that is fixed at right angles to the frame 21 and protrudes toward the sorter 2 side at a predetermined length. Facing the shelf. 23
One end of the link 23 is pivotally supported by the sleeve 17, and the other end is pivotally fixed to a ring body 25 that can be fitted into a guide rod 24 that projects perpendicularly to the frame body 21. Reference numeral 26 denotes a push plate, and the push plate 26 is fixed to a frame body 27 having substantially the same configuration as the frame body 21 and in a position that overlaps with the stop plate 22. The frame body 27 is fixed to the ring body 25. Reference numeral 28 denotes an adjustment screw that is used to adjust the height of the base 9 that is installed and fixed on the floor surface 5.

The cylinder 11 is connected to a suitable fluid supply source, and a solenoid valve is interposed in a part of the fluid supply source. The solenoid valve is electrically connected to a timer or limit switch that opens and closes at regular intervals. The limit switch is configured to operate, for example, when a predetermined number of the last conveyed objects 7 are placed on the mounting table 8.

Next, the operation of the present invention will be explained based on the above embodiment.

As shown in FIG. 4, when a predetermined number of objects 7 are placed on each mounting table 8 of the sorter 2, a limit switch or the like operates to open a solenoid valve (not shown), and the ram 12 of the cylinder 11 moves into the sorter. Projects to the 2nd side. When the ram 12 moves, the stop plate 22 and the push plate 26 simultaneously enter the joint 4 between the sorter 2 and the conveyance device 3 in an overlapping state, and the stop plate 22 prevents the movement of the conveyed items 7 on the conveyance device 3. to stop. Next, stop plate 22
When the support rod 1 stops moving the conveyed object 7,
5 is fully extended, the stopper 15a comes into contact with the end face of the guide block 14a, and the movement of the support rod 15 is stopped. At this time, the ram 12 has not yet fully extended and still has some movement distance left. Therefore, when the ram 12 is fully extended, the support rod 15 cannot move, but the sleeve 17, which is integral with the ram 12,
It moves to the frame body 21 side against the force of 9. Therefore, the link 23 moves the ring body 25 along the guide rod 24 away from the frame body 21. Therefore,
The frame body 27, which is integral with the ring body 25, moves away from the frame body 2 and moves the push plate 26 upward in FIG. Therefore, a predetermined number of objects 7 separated by the stop plate 22 and the push plate 26 on the mounting table 8 are pushed upward in the drawing. Therefore, by providing a stopper 8a at the end of the pushed conveyance object 7 in the moving direction, the predetermined number of conveyance objects 7 can be
As shown in FIG. 5, they are closely aligned and shifted in the sorter 2.

In the above embodiment, the stop plate 22 and the push plate 26 have a multi-stage structure, but this is due to the fact that the sorter 2 has a multi-stage structure. good.

According to the present invention described above, when the number of transported objects 7 that are sequentially stored reaches a predetermined number at the terminal of an automatic transport line that transfers transported objects at regular intervals, the stop plate 22 and the push plate 26 are moved. They are inserted into the terminal of the conveyance device 3 as one body to stop the movement of the conveyance objects 7 on the conveyance device 3, while the push plate 26 aligns a predetermined number of conveyance objects 7 already stored in the sorter 2. Since the two operations of clumping and clumping can be performed with one driving source, the work of manually gathering the objects 7 into predetermined numbers at the end of the automatic transfer line is omitted, reducing the labor burden. In addition, when applied to an automatic conveyance line arranged in multiple stages, it can be configured as a single conveyed object alignment device with multiple stop plates and push plates that advance and retreat from each loading table, greatly improving work efficiency. While the structure is simple, the structure is simple and economical.
