The empty moving carriage transferred to the lower-stage chain conveyor is sent to the loading-side lifter side at high speed. At this time, the carry-in-side lifter is moved down to the level of the lower chain conveyor after being transferred to the cradle side of the moving carriage.

Therefore, the empty moving carriage sent by the lower chain conveyor is transferred onto the carry-in lifter by the lower chain conveyor. At this time, since the piston of the cylinder mechanism of the carry-in side lifter is in the contracted state, the locking piece is not locked by the locking piece locking mechanism with the locking projection of the movable carriage. In this way, after the transfer of the moving carriage onto the carry-in lifter is completed, the carry-in lifter rises again to match the level of the upper chain conveyor.

Then, in the same manner as described above, the constituent members for the housing unit are carried into the empty moving carriage on the carry-in side lifter, and the same operation is repeated thereafter, whereby the predetermined steps are repeated.

Next, the operation of the carrier device 10 according to this embodiment will be described.

With the empty mobile carriage 100 placed on the loading-side lifter 31 in the raised position, the mobile carriage 1
The components for the housing unit are carried in on 00. When this loading is completed, the cylinder mechanism 32 of the loading side lifter 31 is driven, and the moving piece 10 is moved by the locking piece 46.
The locking protrusion 103 in the middle part of 0 is pushed, and the moving carriage 100
The leading end side of is transferred to the upper side of the pedestal 11. On this occasion,
Since the operating speed of the cylinder mechanism 32 is faster than the speed of the first chain conveyor 12 on the upper loading side, the moving carriage 100 newly loaded onto the cradle 11 side is a moving dolly connected to each other on the cradle 11. Of the 100, the rearmost moving carriage 100 is abutted, and the connecting mechanism 105 connects both moving carriages 100.

For the connection, the rearmost moving carriage 1 is connected to the shaft member 107 of the moving carriage 100 pushed by the cylinder mechanism 32.
00 hooks 106 are engaged against the biasing force of springs 108. Further, the position where the connection is made is a position where the delivery of the moving carriage 100 by the cylinder mechanism 32 of the carry-in side lifter 31 is completed, and the moving carriage 1
00 is no longer pushed to the cradle 11 side.

Of the moving carriages 100 placed on the upper side of the receiving table 11, the second moving carriage 100 from the top is shown.
The one locking member 13 of the first chain conveyor 12 on the upper carrying-in side is locked to the locking member 103 in the middle thereof,
It is being slowly moved to the unloading side. When the transfer of the second moving carriage 100 by the one locking member 13 is completed, the cam 111 is positioned below the second moving carriage 100, and the follower 109 engages with the cam 111. By doing so, the hook 106 rotates in the clockwise direction in FIG. 3 against the tension spring 108, and the connection mechanism 105 can be detached. In this state, the chain conveyor 1
When the other locking member 13 of No. 2 is locked to the locking protrusion 103 at the middle portion of the third moving carriage 100, the second moving carriage 100 is in turn moved by the third moving carriage 100. It will be pushed and move forward. By the pressing by the third moving carriage 100, the tip end side of the second moving carriage 100 is positioned above the unloading side second chain conveyor 14 from the middle portion. As a result, the locking projection 103 at the middle portion is provided on the second chain conveyor 14 on the carry-out side.
6 is located in front of the unloading side.

When the chain conveyor 14 continues to be driven in this state, the locking member 16 abuts on the locking projection 103 of the moving carriage 100 to move the leading moving carriage 100 to the unloading lifter 51 side at high speed. It will be towed. At this time, since the connecting mechanism 105 between the leading moving carriage 100 and the second moving carriage 100 is detachable as described above,
The moving carriage 100 on the leading side is smoothly separated from the second moving carriage 100, passes through the second chain conveyor 14, and the tip side thereof is quickly transferred onto the carry-out lifter 51. When the moving carriage 100 is transferred, the moving piece 1 is attached to the locking piece 56 of the cylinder mechanism 52 on the lifter 51.
00, the locking projections 102 and 103 on the unloading side and the intermediate portion of the sheet 00 abut. However, as is clear from FIG. 7, this abutting direction is a direction in which the locking piece 56 is laid down against the compression spring 57, so that the locking piece 56 becomes an obstacle to carrying-in of the movable carriage 100. There is no such thing.

Locking protrusion 103 at the intermediate portion of the movable carriage 100
When the state exceeds the locking piece 56, the transportation of the leading moving carriage 100 by the second chain conveyor 14 is completed. When the cylinder mechanism 52 of the carry-out side lifter 51 is operated in this state, the locking piece 56 is locked by the locking projection 103 in the middle part of the moving carriage 100 by the action of the spring 57, and the piston rod 54 is locked. With the advancement, the moving carriage 100 is transferred to its stroke end, and the transfer is completed.

In this way, the moving carriage 100 on the leading side is
When the sheet is completely transferred onto the carry-out side lifter 51 and stopped at a predetermined position, the assembled components are carried out from the movable carriage 100 on the carry-out side lifter 51, and the movable carriage 100 becomes empty. In this state, the carry-out side lifter 51 is lowered to the level of the lower chain conveyor 17.

The lower-stage chain conveyor 17 is driven counterclockwise in FIG. 1, and the right end side thereof is the loading-side locking projection 1 of the moving carriage 100 placed on the loading-side lifter 51.
It is located to the right of 01. As a result, when the chain conveyor 17 is driven, the locking member 18 of the pair of locking members 18, 19 located on the carry-in side is brought into contact with the carry-in-side locking projection 101 of the moving carriage 100. Mobile trolley 10
0 is transferred to the lower side chain conveyor 17 side.

The lower-stage chain conveyor 17 picks up the movable carriage 100 from above the carry-out side lifter 51, and transfers it to the carry-in side of the lower chain conveyor 17 as it travels. At this carry-in side position, as the chain conveyor 17 rotates, the engagement of the one locking member 18 with the locking projection 101 is released, and the other locking member 19 is now locked in the middle part. The movable carriage 100 is further conveyed to the carry-in side lifter 31 side by coming into contact with the protrusion 103. On this occasion,
The carry-in-side lifter 31 is provided on the moving carriage 100 as described above.
After being sent to the upper stage side of the cradle 11, it is previously lowered to the level of the lower stage side, so that the movable carriage 100 sent out by the lower chain conveyor 17 is transferred onto the carry-in lifter 31.

The piston rod 34 of the cylinder mechanism 32 is used to transfer the movable carriage 100 to the loading lifter 31 side.
Are in a reduced state. Therefore, the locking piece 36 is in the laid state as shown by the solid line in FIG. 6 due to the action of the locking piece non-locking mechanism 41. Therefore, by the transfer of the movable carriage 100 by the chain conveyor 17, the loading protrusions 101 and 103 on the loading side and the intermediate portion are loaded onto the lifter 31 to a predetermined position without being locked by the locking pieces 36. It will be. When the movable carriage 100 is completely transferred onto the carry-in side lifter 31, the lifter 31 is lifted again to match the level of the upper stage side.

In this way, when the empty moving carriage 100 is placed on the lifter 31 and is positioned at the upper level, the constituent members for the housing unit are again carried onto the moving carriage 100, and the above steps are repeated. And then the moving carriage 100
Is carried. During this transportation, the housing unit constituent members are assembled on the upper movable carriage 100.

Incidentally, each chain conveyor 12, 14, 17
Is controlled by a rotary encoder provided in the drive motor of each chain conveyor 12, 14, 17 and a control device such as a computer, and the drive control of each cylinder mechanism 32, 52 is performed by a limit switch and the above-mentioned. It is performed by the control device.

That is, by arranging the chain conveyors 12, 14 and 17 on the upper stage and the lower stage of the cradle 11 respectively, and arranging the lifters 31 and 51 on the carry-in side and the carry-out side of the cradle 11, respectively, the movable carriage 100 is moved.
Therefore, by appropriately setting the length of the pedestal 11, the line for circulating the moving carriage 100 can be easily formed by a required length.

Further, the chain conveyor 12 of the receiving stand 11,
14, 17 and the cylinder mechanisms 32 and 52 of the carry-in side and carry-out side lifters 31 and 51, respectively, at a predetermined speed, and
Since they are driven with their operation timings adjusted to each other, the transfer of the mobile carriage 100 can be carried out very smoothly.
Moreover, the speed of the first chain conveyor 12 on the upper stage side is slowed down, and the second chain conveyor 14 on the carry-out side and the carry-in side,
Since the driving speed of the cylinder mechanisms 32, 52 of the carry-out side lifters 31, 51 is increased, the connection and disconnection of the moving carriage 100 can be performed extremely smoothly.

Further, the transfer of the movable carriage 100 is performed by the locking members 13, 14 provided on the respective chain conveyors 12, 14, 17.
