Elevating conveyance device

Abstract

The present invention proposes an elevating conveyance device with improved versatility which can be utilized for transferring an automobile body in an automobile assembly line, etc., and according to a first aspect of the invention, the elevating conveyance device includes a multistage extensible column, a transfer means, and an extending and contracting drive mechanism, where the multistage extensible column includes a fixed column portion, one or more mid-stage elevating column portions, and a final-stage elevating portion, the transfer means is provided on the final-stage elevating portion, and the extending and contracting drive mechanism includes a counter weight supported on the fixed column portion movably vertically in a range of the height of the fixed column portion, a winding transmission tool which applies the gravity of the counter weight upward to the next mid-stage elevating column portion, an elevating drive means which drives and elevates the next mid-stage elevatingcolumn portion with respect to the fixed column portion, and winding transmission tools which convert an upward movement of the mid-stage elevating column portion into an upward movement of the next mid-stage elevating column portion or final-stage elevating portion.

Description

technical field [0001] The present invention relates to an elevating and conveying device that can be utilized for transferring automobile bodies in an automobile assembly line, and the like. Background technique [0002] As the lifting and conveying device that can be used for the transfer of automobile body etc., it is known that there is a device for loading a transfer mechanism that can move forward and backward in the horizontal direction on the lifting table of the table lifter form; As described, a descending lifter-type device in which a moving mechanism capable of advancing and retreating in the horizontal direction is mounted on a lifting body that can be raised and lowered along the pillar. In addition, lifting transport devices in the form of articulated robots are known which can be used for transfer devices. [0003] The elevating and conveying device in the form of a table lifter and the elevating and conveying device for transfer in the form of a multi-joint...

AI Technical Summary

Problems solved by technology

[0003] The elevating and conveying device in the form of a table lifter and the elevating and conveying device for transfer in the form of a multi-joint robot do not need to be designed and arranged in any respect, as long as it is a solid floor, they can be installed freely and used flexibly. If the transfer point is small, it cannot be used flexibly

However, in the lifting transport device for transfer in the form of an articulated robot, the degree of freedom of the transfer path is high, but there is a disadvantage that the cost of equipment is greatly increased.

In contrast to this situation, in the lifting and conveying device in the form of a descending lifter described in Japanese Patent Application Laid-Open No. 58-92221, the head is increased, but the top of the pillar must be connected and supported with the beams on the patio side, and it cannot be simply installed on the floor

Namely, has the disadvantage of lacking versatility
