Problems to be Solved by the Invention According to the conventional method described above, one carrier can only transport one door, resulting in inefficient transport.

An object of the present invention is to provide a suspension conveyance device using pallets that can stably convey a plurality of plate-like objects at the same time.

Means for Solving the Problems In order to solve the above problems, the hanging conveyance device using pallets according to the present invention is provided with a movable body that is supported and guided by rails and can freely run on a fixed path. A hanger is provided which has a plurality of pairs of left and right upward engaging tools in the front-rear direction, and has an engaged tool that can be freely engaged and disengaged between the left and right pairs of engaging tools, and a plurality of engagement tools are arranged in parallel in the front-rear direction with respect to the hanger. A pallet is provided on which a plate-like object can be placed vertically.

According to the configuration of the present invention, the let, which supports the plate-like object through the receiving tool, is stabilized on the hanger side by engaging the engaged tool between the left and right pair of engaging tools. Furthermore, a plurality of pallets can be supported in the longitudinal direction of the hanger.

Embodiment An embodiment of the present invention will be described below based on the drawings.

In FIGS. 1 and 2, 1 is a movable body that is supported and guided by rails 2 and can freely run on a fixed path 3.
It is composed of a power trolley 4, a load trolley 5, and a frame 6. The rail 2 is supported on the ceiling beam 8 side via a bracket 7. The power trolley 4 has a drive wheel body 1 attached to the top of a trolley body 9 to be placed on the top surface of the rail 2.
0, and a traveling drive device 11 which is provided on the trolley body 9 and can be freely driven in forward and reverse directions to operate in conjunction with this drive wheel body 10.
and a guide roller 12 provided on the trolley body 9 to face the side surface of the rail 2. The load trolley 5 also includes a driven wheel 14 attached to the upper part of the trolley body 13 to be placed on the upper surface of the rail 2, and a guide roller 15 provided on the trolley body 13 to face the side surface of the rail 2. configured. A power supply device 16 is disposed on the side surface of the rail 2 over the entire length, and the power trolley 4
A current collector 17 is provided on the trolley body 9. The frame 6 is connected to the lower end sides of both trolleys 4 and 5 via trunnion pins 18 and 19, respectively. A hanger 20 is attached to the lower part of the movable body 1, and the hanger 20 has a plurality of left and right pairs of upward engaging members 21A, 21B in the front and back direction. That is, the hanger 20 has a pair of front and rear gate-shaped members 22 when viewed from the front, and the top frame portions of these gate-shaped members 22 are fixed to the frame 6. And between the front and rear lower ends of both gate-shaped members 22, receiving members 23A, 23
B is attached, and the pin-shaped engaging members 21A, 21B are protruded from the upper surfaces of these receiving members 23A, 23B at predetermined pitches P in the front-rear direction. Stopper pieces 24 are provided at the front and rear ends of the receiving members 23A and 23B.
A and 24B are attached. Reference numeral 25 denotes a long plate-shaped pallet, the width W of which is set slightly shorter than the predetermined pitch P. At both ends of the pallet 25, in the center of the width W, there are a pair of left and right engaging tools 21A,
Hole-shaped engaged tools 26A, 2 that can be freely engaged and detached between 21B
6B is provided. In this embodiment, the engagement tool 2
Pin-shaped items as 1A and 21B, engaged tool 26
Although hole-shaped holes are shown as A and 26B, they may be reversed, or other means for engaging and disengaging in the vertical direction may be used. A car door 27, which is an example of a plate-like object, is mounted on the upper surface of the pallet 25.
A lower end receiver 28 and a side receiver 29 are provided to support the lower end receiver 28 and the side receiver 29.

In FIGS. 3 and 4, a slat conveyor 35 supports and conveys a body 36. Said fixed route 3
The rails 2 forming the slat conveyor 35 are branched, run along both sides of the slat conveyor 35, and join together after a certain distance of separation. Here, one of the branch paths is for the left door, and the other is for the right door. An upper elevating rail 38 is provided at the starting end of the two divided sections via an upper elevating device 37, and a lower elevating rail 40 is provided at the end portion via a lower elevating device 39. A relay rail 41 is fixed between the two lifting devices 37 and 38 at an intermediate position in the vertical direction with respect to the rail 2 arranged near the ceiling. The starting and ending ends of both the lifting rails 38 and 40 can be selectively connected to the rail 2 and the relay rail 41 by raising and lowering them. A pallet holder 43 is placed below the relay rail 41 via a lift device 42.
will be provided.

Next, the operation of the above embodiment will be explained.

The movable body 1 is a driving wheel body 1 by a traveling drive device 11.
By rotating the robot 0, it is supported and guided by the rails 2 and travels on a fixed route 3. The movable body 1 with the empty hanger 20 is branched and transferred to the slat conveyor 35.
After traveling along the upper elevation rail 38, the vehicle reaches its upper limit. And upper lifting rail 38
By descending and connecting to the relay rail 41, the movable body 1 travels from the upper elevating rail 38 to the relay rail 41. The movable body 1 on the relay rail 41 is stopped after passing through the lift device 42. In this state, a predetermined number of pallets 25 are placed in parallel on the pallet holder 43 of the lift device 42, with the direction of the width W being the front-rear direction (the moving direction of the movable body). Then, the door 27 is removed from the body 36 conveyed on the slat conveyor 35, and the door 27 is stacked on the pallet 25 via both receivers 28, 29. With all the pallets 25 loaded with doors 27, these pallet groups 25 are lifted via a pallet holder 43 which is raised by the operation of a lift device 42. Next, the movable body 1 is moved backward, and the receiving members 23A and 23B of the hanger 20 are pushed into the lower part of the pallet group 25. Then, by moving the lift device 42 downward, the receiving materials 23A, 2 on both sides of the pallet 25 group are
3B, but at that time the engaging tool 21
The engaged tools 26A and 26B engage with the pallets A and 21B from above, and the pallets 25 are positioned. Next, the movable body 1 is moved forward,
Move onto the lower elevating rail 40 at the lower limit.
Then, as the lower elevating rail 40 rises and connects to the rail 2, the movable body 1 moves to the lower elevating rail 40.
From then on, it transfers to rail 2 and travels to the next process.

Note that the unloading operation via the pallet 25 may be carried out individually one by one, and the loading may also be carried out one by one.

Effects of the Invention According to the present invention having the above configuration, the pallet that supports the plate-like object through the receiver can be moved toward the hanger side by engaging the engaged tool between the left and right pair of engagement tools. It can be stably supported, and moreover, a plurality of pallets can be supported in the front and rear directions of the hanger. This allows a single movable body to transport a plurality of plate-like objects at the same time efficiently and stably.
