FIG. 2 is a schematic exploded view of the operation of adjusting the movable side plate, and a partly omitted plan view taken along the line II-II of FIG. 1, and FIG. 3 is a perspective view of a schematic device for continuously implementing the present invention. FIG.

First, before describing the device of the present invention in detail, each member of the rack applied to the present invention will be described in more detail with reference to FIGS. (10,1
0a) is a panel P engraved on a fixed movable side plate (4, 5).
The parallel groove for support, (14) is a long member such as a channel member for supporting both side plates, and sliders are provided at both ends of this member (14) attached to the outside of the movable side plate. (3) is a column which is provided between the upper and lower plates (1, 2) on the opposite side of the fixed side plate. (11) and (21) are rotating vertical and horizontal axes passed between adjacent pinions, and (22) and (25) are racks engraved on horizontal and vertical planes of the rack rail, respectively, and horizontal pinions (8) respectively. And vertical pinion (9). (28) is an enlarged portion of a tension rod protruding from the fixing piece (26) inscribed in the upper and lower plates through the elongated hole (6), and is engaged with and removed from the elongated hole by pivoting of the lever (32).

The movable side plate engaging and disengaging device is mounted as an assembly on a table (70) reciprocating on a gantry (40) sideways, that is, toward a rack to be adjusted. The gantry houses a uniaxial movement mechanism using a motor and a ball screw, whereby the table (70) reciprocates. Hydraulic cylinder in assembly (4
1) reciprocating shaft from (pneumatic, hydraulic, etc.)
That is, the rod (42) is connected to the link mechanism (4) via the bearing (43).
4) has reached the base (45). A pair of fulcrums at the base (46,
From 46a), a plurality of single nodes of the same shape are connected symmetrically up and down via a fulcrum. Horizontal single bar (47), fulcrum (48), vertical single bar (49),
The terminal fulcrum (50), the diagonally upward single articulation (51), and the fulcrum (52) reach the open-ended gripper (53). It is pivotally connected to an arm (56) projecting inward from (55). The plate (55) and the gripper (5
3) is pivotally connected to a rod (57) extending from the plate and a fulcrum (58). Thus, the plate piece (55) is pivotally symmetrically connected to the lower link mechanism (members are given the same numbers with a). A pusher (60, 60a) projects forward from substantially the center of the plate piece. The position of the pusher is the long member of rack (7) (14)
Is provided at a position corresponding to the mounting position. (61) is a sensor attached to the table (70), which moves the table toward the movable side plate and checks the position of the side plate. The confirmation is transmitted to the moving mechanism via the electronic element (62) to stop the movement of the table.

The holding device includes a pair of rotary actuators (65, 65a) on both sides of the fluid pressure cylinder (41),
Holding arms (66, 66a) and rods (67, 6) connecting them
7a), and these mechanisms are attached to the table (70) and reciprocate with the table. The actuator is rotated by 90 degrees in response to a command to lower the arm (66) from the upright position shown by (66a) to the horizontal position shown by (66). (FIG. 2). Since the position of the arm cooperates with the pusher (60) as described later, it is desirable that the arm is at the same height as the pusher.

Starting the table, stopping by sensing with a sensor,
Also, since the automatic operation of sequentially performing the backward movement, the actuation of the fluid pressure cylinder actuator, and the movement thereof can be performed without the inventor of the skilled artisan, details of the electric circuit, the fluid pressure system diagram, etc. Is omitted.

Next, the rack (7) is placed on the conveyor (71), transferred to the adjusting device (73) beyond the input sensor position (72), and stopped (FIG. 3). As described above, since the outer surface of the movable side plate faces the device (73), the table (70) accommodated in the main body (74) enters the rack and is moved by the sensor (61). When the position is confirmed and stopped, the reciprocating shaft (42) moves forward by the action of the fluid pressure cylinder (41),
Accordingly, the pusher (60) is pressed against the outer surface of the side plate (5). At this time, the gripper (53) grips the rack pivot lever (32). When the shaft (42) is further advanced, the upper and lower link mechanisms move to the position symmetrical with the imaginary line in the lower part of FIG. 1, and the gripper (53a) reaches the position (53b). The side plate (5) is disengaged from the upper and lower plates (1, 2) by tilting the 32) to the (32m) position. At this point, since the rods (67, 67a) of the holding device have already extended from the outside of the rack pillars (3) to both sides of the side plate (5), the rods are rotated by the action of the actuators (65, 65a). By the movement, each of the holding arms (66, 66a) rotates to the state of the arm (66), and holds the side plate (5) in cooperation with the pusher (60, 60a). In this case, as described above, it is preferable that the pressing tool does not directly contact the side plate (5) but abuts on the long member (14) of the side plate to be pushed. Thus, after holding the pusher and the holding arm, the table is moved by the transmission mechanism in the gantry to move the side plate (5) to an appropriate position with respect to the fixed side plate along the rack rail, and then perform the above operations. Move it back to fix the movable side plate and discharge it via the conveyor.

〔The invention's effect〕

As described above, the method and apparatus of the present invention perform the engagement and disengagement of the movable side plate on the inner surface of the rack, so that there is no complicated operation conventionally performed from the outside of the rack as in the operation of this type of apparatus. In addition, the movable side plate is extremely reliably moved by the joint action of the pusher and the holding arm by operation from the outside of the side plate,
In addition to being accurate, no operation means is added on the opposite side of the movable side plate, particularly on the outside of the fixed side plate.
