This is also an indication. In the illustrated example, the locking devices ig are two engaging pawls 31 pivotally mounted on the operating frame 17 by bolts 30, respectively. Engagement claw 3
/ can be rotated between a locked position shown by a solid line in the drawing and a non-locked position shown by a dashed line. In the locking position, the engaging pawl 3/ protrudes from the side surface of the working punch 17 and its locking surface 32 is approximately perpendicular to the long axis of the working punch 17. In the non-engaging position, the engaging claw 3
/ is within the area defined by both sides of the working punch 17.

Therefore, when the engagement claw 31 is in the engagement position, the loading platform/
, can be engaged with the corner of load/4' on a or 3, but if it is in the uncoupled position, it can pass through the space between the aligned loads/4 (without contacting the load). It is.

In this way, in order to open and close the engaging claw 3/ of the engaging device/g and operate it to the engaged position or the non-engaged position according to the operation of the operating punch/7, the following device is constructed. A locking device control device is provided.

A locking piece 33 is fixed to each engaging claw 3/ by welding or the like, and both ends of a biasing device 3'l, which is a spring, are fixed to the locking piece 33. The biasing device J'l is configured to bias the engaging claws 3/ apart from each other and into the locking position by a spring action. The opening degree of the engaging claws 3/ is limited by a stopper 33 between the engaging claws 31 fixed on the operating frame 17.

On the operating frame 17, there are provided a locking member 3A that is slidably provided relative to the actuation (rlX/7) and an electromagnetic solenoid 37 that operates the locking member 36. The tip of the plunger 39 is connected to the tail end of the latching member 36.The latching member 3B slides in the axial direction by a bearing iii fixed to the operative punch/7. The tip of the latch claw is provided with a latch claw '%/ and the bearing l.
A compression spring is provided between the IO and the IO. The latching claw lI/ engages the latching piece 33 of the engagement device ig when the engagement claw 31 of the engagement device ig is in the non-engaged position shown by the dashed line in FIG. It is movable between a latching position where it is held in a non-latching position and a non-latching position where it retreats from the latching position and the latching piece 33 cannot be latched. The compression spring '12 is the latching member 3
When the electromagnetic solenoid 37 is energized, the latching member 36 is moved back from the latching position to the non-latching position against the biasing force of the compression spring 112. I can do it.

Furthermore, strikers 11, 3 are provided on each of the loading platforms 1 to 3 at positions that contact the engaging claws 31 of the engaging device/g that is in the locking position when the operating punch 17 reaches the protruding position. is fixed. The striker 1I3 can contact the cam surface of the engagement claw '31 and rotate the engagement claw 3/ from the engagement position to the non-engaged position. Immediately before the engaging claw 31 reaches the non-locking position, the latching piece 33 of the engaging claw 31 and the latching member 3
6 may come into contact with the latching claw ll/, but the latching piece J
Since the contact surfaces of 3 and latching claw 1/ are inclined with respect to their relative movement direction, latching member 36 is retracted against its compression spring force and pushed to the non-latching position. This does not prevent the engaging claw 3/ from reaching the locking position. After the latching piece 33 passes the latching claw F/, the latching member, ? 6 is returned to the latching portion 1iJe by the compression spring 4t, so that the engagement claw 3/ can be held in the engagement position.

The locking device control device further includes a heavy source, a relay, and a heavy source for controlling the operation of the electric motor for driving the operating frame and the electromagnetic solenoid 37 for operating the latch member according to the position of the operating frame.
It includes 14 electrical circuits including switches, etc. Such electrical circuits can be easily designed by those skilled in the art.

This electric circuit may be one that manually controls the operation of the locking device 1f using a manual switch, or one that automatically controls the operation using a limit switch installed at an appropriate position. It is also possible to operate automatically in conjunction with the operation of the elevator.

The conveying device of the present invention constructed in this manner can be operated as follows. Loads such as loaded trolleys or empty trolleys/4! First, they are distributed on one of the loading tables as shown in FIGS. 3 and 9. The movable loading platform 13 is stopped on the loading platform, and the electric motor/9 is driven to move the operating frame 17 toward the protruding position. At this time, the electromagnetic solenoid 37 on the operating frame 17 is deenergized and the latching member 36 is in the latching position, holding the engaging pawl 31 in the non-latching position, so the operating frame 17 moves between the loads. It can be moved toward the protruding position while being guided by the guide device Koda. When the operating frame 7 reaches the protruding position, the engaging claw 3 at the tip enters between the striker 73, and the tip of the operating frame 7 hits a limit switch (not shown), causing the operating frame 17 to move. Driving electric motor/? stop. Next, the electric motor /q is reversely rotated and the electromagnetic solenoid 37 is energized at the same time. Then, as the operating frame 17 moves toward the retracted position, the engagement pawl 3/ comes out from between the strikers 73 and is opened by the spring 3 to reach the engagement position. The three engaging surfaces of the engaging claw 3/ in the engaging position engage with the load/l and the operating frame/

In this state, the movable loading platform 13 can be moved to any of the other loading platforms. In the illustrated example, the movable cargo platform 3 is an elevator car, which can be raised and lowered and stopped at each platform in the same manner as a known elevator.

The moving loading platform 13 stopped at the desired loading platform, Mr. Electric.
is energized to move the operating frame 17 from the retracted position to the extended position. At this time, the electromagnetic solenoid may remain energized or deenergized.

The load/data is pushed by the horizontal member 27 on the operating frame lt and is pushed out onto the loading platform together with the operating frame 17.

When the operating frame 17 reaches the protruding position, the engaging claw 3/
The cam surface 1III of the striker 11 and 7 hits the non-coupling position 16. , and is held in the unlatched position by the hooking member 36. In this state, the tip of the 11fb rod/7 hits the limit switch again and activates the electric 4+H/
9 is stopped and reversed to retract the operating frame/7. At this time, the engaging claw 3/ of the operating frame /7 remains in the non-engaging position, so it is not engaged with the load/lI and is pulled into the movable loading platform/3 while leaving the load/da on the loading platform. Can be pulled into position. This state is the same as the state in which the operating frame/7 initially moves toward the protruding position. In this way, the conveying device,
It can be operated repeatedly.
