Embodiments of the present invention will be described below.

FIG. 1 is an elevational view showing an embodiment of a bogie handling device according to the present invention. FIG. 2 is a plan view of the bogie handling device shown in FIG.
FIG. 3 is a side view of the bogie handling apparatus shown in FIG. 1, and FIG. 4 is an elevation view (elevation viewed from the back side of FIG. 1) of the bogie.

In these drawings, reference numeral 1 denotes a bogie having a plurality of wheels 12 attached to a lower portion of a base 11; 2 a support for supporting the lower portion of the base 11 and the wheels 12; The support 2 supports a part of the wheels 12 (121) of the plurality of wheels 12, and the lower part of the base 11 of the trolley 1 is supported by the support 2. The trolley 1 is raised by the support 2 supporting the lower part of the base 11 of the trolley 1 and the wheels 121, being supported between the wheels 121 supported and the wheels 122 not supported by the support 2. It can be (handled). Reference numeral 4 denotes a chain conveyor for transporting the carriage 1, and a lifter 3 is provided at a downstream end of the chain conveyor 4. Reference numeral 5 denotes a fork device for taking out the carriage 1 raised by the lifter 3.

To explain each part in the above embodiment, the cart 1 is a rectangular base 11 for mounting articles.
A plurality of (four) wheels (swing casters rotatable in a planar direction) 12 are attached to the lower part of the base 11, and a bar-shaped article fall prevention body 13 And is configured to be able to move a floor or the like in a desired direction by human power. Base 1
Reference numeral 1 denotes a plate-like body or a plate-like body having a central portion formed in a net shape.

The support base 2 is a part (two) of four wheels 12 (wheels located in the upstream direction of the chain conveyor 4) of the four wheels 12 attached to the base 11 of the carriage 1.
21 are supported by a pair of wheel support portions 21, respectively, and the lower part of the base 11 of the carriage 1 is supported by the wheel 121 supported by the wheel support portion 21 and the wheel not supported by the support base 2 (the chain conveyor 4). And two pairs of base support portions 22 at left and right edges between the two wheels 122 located in the downstream direction. Note that the wheel support 21 is formed in a planar shape, and the base support 22 is formed in a line segment. The difference in height between the wheel support 21 and the base support 22 is as follows:
This corresponds to the mounting height of the wheel 12.

The lifter 3 is provided with a pantograph-type elevating mechanism so as to elevate and lower the support table 2, and is disposed at a downstream end of the chain conveyor 4, and is provided at a downstream end of the chain conveyor 4. The trolley 1 transported up to this point is lifted via the support base 2 and taken out by the fork device 5.

Further, the chain conveyor 4 transports the cart 1 by tact feeding, and a plurality of (for example, 7) carts 1
And a drive chain conveyor for transporting the carriage 1 to the downstream end by tact feed.

The fork device 5 is a device for taking out the carriage 1 lifted by the lifter 3, and is mounted on a traverser 51 which moves in a direction perpendicular to the direction of transport of the chain conveyor 4, and is installed in the traverser 51. The stored fork device 5 is configured to move forward and backward in the direction of the chain conveyor 4.

Next, the operation of the truck handling apparatus of the above embodiment will be described. An operator introduces the conveyor (not shown)
When the cart 1 is supplied above, the operation of the introduction conveyor is automatically started. When the operation of the introduction conveyor is started, the carriages 1 are started to be transferred one by one to the upstream side of the chain conveyor 4 via the introduction conveyor.

When the transfer of the truck 1 is started to the upstream side of the chain conveyor 4, the chain conveyor 4 is adapted to convey the truck 1 by tact feeding, so that the chain conveyor 4 is operated and the transfer is started. When the cart 1 is completely transferred to the chain conveyor 4, it stops.

Similarly, when the next carriage 1 is started to be transferred to the upstream side of the chain conveyor 4,
Is operated again, and stops when the truck 1 whose transfer has been started is completely transferred to the chain conveyor 4. Similarly, a plurality of (for example, seven) carts 1 are pooled on the chain conveyor 4.

When the seven trucks 1 are pooled on the chain conveyor 4, the chain conveyor 4 is operated until the downstream truck 1 reaches the downstream end of the chain conveyor 4, and
The seven carts 1 each advance in the downstream direction.

When the truck 1 on the downstream side reaches the downstream end of the chain conveyor 4, the lifter 3 is operated, and the truck 1 located at the downstream end of the chain conveyor 4 is moved to the base 11 via the support base 2. And the wheel 121 is supported and lifted. At this time, the four wheels 12 attached to the base 11 of the cart 1
Of the wheels (wheels located in the upstream direction of the chain conveyor 4) 121 are a pair of wheel support portions 2 of the support base 2.
1 and the lower part of the base 11 of the carriage 1 has wheels 121 supported by the wheel support 21 and wheels not supported by the support 2 (located in the downstream direction of the chain conveyor 4). 2 wheels) 1
At two locations on the left and right edges between the base 22 and the base 22, the pair of base supports 22 of the support base 2 are supported.

When the bogie 1 located at the downstream end of the chain conveyor 4 is lifted up, the fork device 5 stored in the traverser 51 advances in the direction of the chain conveyor 4, and the lifted bogie 1 It is inserted into the space formed below.

When the fork device 5 is inserted into the space formed below the lifted truck 1, the lifter 3 descends, and the lower portion of the base 11 of the truck 1 is supported by the fork device 5 during the downward movement. Thereby, the cart 1 is transferred onto the fork device 5.

When the trolley 1 is transferred onto the fork device 5, the fork device 5 retreats, and the trolley 1
1 is stored (transferred) and taken out.

When the carriage 1 located at the downstream end of the chain conveyor 4 is taken out, the chain conveyor 4 is operated until the next carriage 1 reaches the downstream end of the chain conveyor 4, and the next carriage 1 is moved to the next position. When the vehicle reaches the downstream end of the carriage 4, the lifter 3 similarly operates the next bogie 1
Is lifted up and taken out by the fork device 5.

The embodiment of the present invention has been described above.
The truck handling device of the present invention is not limited to these. For example, it can be handled even when the bogie is a unicycle.

The shape and size of the support 2 (the wheel support 21 and the base support 22) may be appropriately designed according to the shape and size of the truck 1. If appropriately designed, a plurality of types of trolleys 1 can be handled by one type of support 2.

When handling a plurality of types of trolleys 1 having different dimensions (heights) of the wheels 12, the sub-lifter (for raising and lowering the base support 22) can be moved up and down integrally with the wheel support 21. With such provision, the difference in height between the wheel support portion 21 and the base support portion 22 can be appropriately changed according to the size (height) of the wheel 12.

[0030]

Since the bogie handling device of the present invention is constructed as described above, the bogie can be lifted (handled) by the supporting base supporting the lower part of the base of the bogie and the wheels, and Can be transferred (taken out) by a fork device or the like without using a pallet or the like.
