Friction driven swing conveyor

Abstract

The invention provides a friction driving type trolley conveyor which can make a trolley vertical structure compact, save space for conveyor installation in a horizontally bent region, and certainly convey a conveyed article. The friction driving type trolley conveyor 10 has guide rollers 12a and 12a and travel wheels 12b and 12b travelling in a hollow conveyance rail 11 along a conveyance line L. The trolley conveyor 10 comprises many conveyance trolleys 12 that carry the conveyed article W and move along the hollow conveyance rail 11, a passive bar 13 for connection pivoted to the rear end pivot section 12f of a precedent conveyance trolley 12 and the front end pivot section 12e of a following conveyance trolley 12 in a bridged state, and a friction driving means 15 for slidably moving the passive bar 13 for connection. The passive bar 13 circumferentially moves in the horizontally bent region of the conveyance line L while projecting from an inner peripheral side slit 11d of the hollow conveyance rail 11, and straightly moves in the hollow conveyance rail 11 in a linear region of the conveyance line L.

Description

technical field [0001] The present invention relates to a hoisting conveyor for hanging and conveying objects, in particular to a hoisting conveyor for conveying the main body of an automobile by hanging from a ceiling on an automobile production line, and used for conveying to various processes such as a welding process and a painting process. technical background [0002] In the past, the friction-driven lifting conveyor for hanging and conveying the conveyed objects, as shown in Fig. 7 and even Fig. 9, consists of the following parts: a conveying guide rail 31 with a circular cross section extending along the conveying line L, A plurality of J-shaped guide rail suspension parts 32 that carry the lower part of the aforementioned conveying guide rail 31 at predetermined intervals, a plurality of inverted J-shaped hook parts 33 that slide longitudinally along the upper part of the aforementioned conveying guide rail 31 on the guide rail, and horizontal frames on the aforement...

AI Technical Summary

Problems solved by technology

[0009] Therefore, in order to achieve the compactness of the installation space of the conveyor, if the radius of curvature of the horizontal bending area is reduced, the driven rod 34 for conveyance will protrude greatly from the arc track of the guide rail 31, which may cause unstable conveyance or loss of conveyance balance or contact with the surrounding area. There is a problem that the radius of curvature of the horizontal bending area cannot be reduced due to the contact collision of the configuration object, etc.
