Description

Description: TECHNICAL FIELD The present invention relates to a transport device that enables transport in multiple dimensions, and more specifically, a plurality of transport blocks are connected to form a transport body, and the transport body is transported. The present invention relates to a multidimensional transport device provided so that a side and a return side are located above and below in a transfer path.

In a conventional transfer device of this type, a large number of transfer blocks that are connected in a string are contacted and supported by a surface with respect to a support surface of a liner that guides the transfer block. Is done by sliding the support surface of the liner.

Therefore, when the conventional transporting apparatus is used, since a large number of transporting blocks and the liner supporting surface are in surface contact with each other, a large horsepower is required to drive the transporting body.

Lubricating oil is required in order to improve the slippage between the multiple transport blocks and the liner support surface.

The use of lubricating oil between a large number of transport blocks and the liner support surface limits its use in transporting foodstuffs and the like.

The contact surfaces between a large number of transport blocks and the liner supporting surface are heavily worn and easily damaged.

If foreign matter enters the contact surface between a large number of transport blocks and the liner support surface, it is difficult to remove the foreign matter, resulting in a failure.

It had some drawbacks and was not very practical.

SUMMARY OF THE INVENTION The present invention is intended to eliminate the drawbacks of these conventional apparatuses, and is two rollers whose axial directions are orthogonal to the lower surfaces of the left and right sides of each of the transport blocks forming the transport body. Are provided in the U-shaped liner provided corresponding to the vertical position along the inside of the left and right guide plates in the transfer path formed by providing the left and right guide plates in parallel with each other. By supporting a roller having a horizontal axis in the transport block, the linear movement in each transport block forming the transport is performed by the U-shaped liners provided above and below the left and right in the transfer path. It will be done by the rolling contact of the rollers inside, the transport side of the carrier,
