[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer line applied to, for example, transfer of heavy goods in a factory.

[0002]

2. Description of the Related Art FIG. 3 is an explanatory view of a conventional roller line used for transporting heavy goods in a factory. In the figure, a conventional roller line is provided with a rigid base 02 on a floor surface 01 so that a heavy work 07 can be transported, and a plurality of sprocket-equipped rollers 04 installed on the base 02 via bearings 03. The work 07 on the roller 04 is conveyed by rotating the roller 04 via a chain 06 by a motor 05 equipped with a speed reducer provided on the gantry 02.

[0003]

In the conventional roller line as described above, it is difficult for a person or a vehicle to cross the roller line because the gantry 02 and the like are provided so as to protrude from the floor surface. In addition, a hoist is required to transfer the heavy work 07 on the roller line. In addition, when the roller line is looped, it is necessary to provide a sloped roller at the corner of the roller line or use a traverser, and the manufacturing cost is high because the roller line has a large structure. Becomes

[0004]

The transport line of the present invention is:
A roller chain provided in a loop groove on the floor surface and rotating, a plate attached to the roller chain to form a lid for the groove, a frame provided on an upper surface of the plate ,
The stopper provided at the tip of the frame is engaged with the
And a carriage that is pulled by the plate and moves on the floor .

[0005]

In the above, the load loaded on the carriage is transported.
If you want to use
After engaging with the frame provided on the upper surface of the roller chain,
To move the truck by pulling it with the plate,
Transfer the load. The roller chain is placed on the floor near the groove.
Because it is connected to a plate that slides on the surface,
It does not fray and this plate is a roller chain
To cover the upper part of the groove,
The lid is provided on the entire surface, and the floor surface is flat.

[0006]

1 and 2 are explanatory views of a transfer line according to an embodiment of the present invention. In the drawing, the transfer line according to the present embodiment is used for transferring a heavy object in a factory, etc., and has a concave shape formed of an angle 2a and a joint plate 2b on a floor surface 1 so that a heavy work 6 can be transferred. The groove 2 is provided in a loop shape, and a roller chain 3 with a plate 3a is provided in the groove 2 in a loop shape so that the plate 3a of the roller chain 3 serves as a groove cover, and a splot 4a for driving the roller chain 3 is provided. Is provided under the floor 1a with a speed reducer. A cylindrical or rectangular frame 3b for pulling the cart 5 is appropriately provided on the plate 3a of the roller chain 3, and a slide-type stopper 5e is provided in front of the cart 5 so as to be engageable with the frame 3b. ing. The cart 5 has turning wheels 5a in the front and fixed wheels 5b in the rear, and the plate 3a of the roller chain 3
It is set on the upper frame 3b via a stopper 5e. In the figure, reference numeral 5c denotes a bracket, 5d denotes a pipe, and 5f denotes a handle.

When the workpiece 6 is transported by this transport line, the carriage 5 on which the workpiece 6 is loaded is moved on the plate 3a of the roller chain 3 and the stopper 5e in front of the carriage 5 is moved onto the plate 3a of the roller chain 3. Set in the frame 3b. Then, by operating a motor 4 with a speed reducer for driving the roller chain 3, the splat 4a rotates to move the roller chain 3, and the carriage 5 is pulled to a predetermined position to convey the work 6. After transporting the work 6, the carriage 5 is pulled to the original position by the roller chain 3,
By removing the stopper 5e of the carriage 5 from the frame 3b,
Is released from the plate 3a of the roller chain 3.

[0008] In the conventional roller line, it is difficult for a person or a vehicle to cross the roller line because a gantry or the like is provided to protrude from the floor surface, and a heavy work is transferred on the roller line. When a roller line is to be looped, it is necessary to provide a sloped roller at the corner of the roller line or to use a traverser, etc. However, in the present transport line, a groove 2 is formed in a loop on the floor 1 and a roller chain 3 with a plate 3a is provided in the groove 2 to form a plate 3a of the roller chain 3. Is a groove cover, and a motor 4 equipped with a speed reducer to which a splat 4a for driving the roller chain 3 is attached is mounted under the floor 1a.
And a carriage 5 on which the work 6 and the like are loaded is set on the plate 3a of the roller chain 3.
By adopting a structure in which the carriage 5 for transporting the work 6 is pulled by the loop-shaped roller chain 3 buried in the floor 1, it is possible to cope with the transport in the linear portion and the corner portion with a simple structure.
People and vehicles can cross the transport line, which is safe and the working environment is improved. In addition, when the carriage 5 is released by the towing unit, it becomes free, and the work 6 can be replaced with the carriage 6 on the transport line without using a hoist. Also,
By having the most simplified structure, there is an advantage that it can be manufactured at low cost.

[0009]

[Effects of the Invention] The transport line according to the present invention is configured as described above, and since the transport line does not protrude from the floor surface and the floor surface is flat, people and vehicles can easily cross the transport line. In addition, it is possible to transfer heavy objects together with the bogies on the roller line without using a hoist, and it is not necessary to provide a gradient at the corner of the transfer line or use a traverser etc. Is simplified and the manufacturing cost is reduced.
