Trolley conveying device

Abstract

The present invention provides a trolley conveying device which does not require a transportation device or a conveying path between a loading side transportation device and an unloading side transportation device for the empty trolley. The trolley conveying device is provided with the following components: a non-automatic conveying object trolley (1) which supports the conveying object (W) and can move along a rail (R) that forms a conveying line (L); a non-automatic operator trolley (2) which is separated from the conveying object trolley (1) and is provided with a supporting plate (21) for seating of an operator; a trolley driving mechanism (3) which drives the trolley; a combination mechanism (4) which combines the conveying object trolley (1) with the operator trolley (2) at an upstream side of an operation process (P1); a separation mechanism (5) which separates the conveying object trolley (1) from the operator trolley (2) at a downstream side of an operation process (P2); and a withdrawing mechanism (6) which withdraws the operator trolley (2) that is separated by the separation mechanism (5) to the upstream side of the operation process (P1).

Description

technical field [0001] The present invention relates to a trolley conveying device for conveying a non-self-propelled trolley supporting a conveyed object along a rail, and more particularly to a conveying line in which an operator rides on a trolley to perform work on the conveyed object. The trolley conveying device used in the Background technique [0002] As a trolley conveying device that transports a non-self-propelled trolley that supports a conveyed object along a rail, there is a device that supports a long conveyed object and runs on a curved path with a small curvature radius. A non-self-propelled movable body that connects 4 trolleys (guided devices) with 3 frame bodies to support the conveyed objects in a curved manner, and engages the trolleys with the rails, and the rails form a linear path. The elliptical ring-shaped predetermined path composed of the front and rear movable bodies and the curved path portion is provided with a propulsive force by a friction ...

Problems solved by technology

[0011] In addition, although it is not shown in FIG. 10 of Patent Document 2, in order to transfer the empty trolley to the unloading cart, the conveyed object is transferred from the upstream side line and the conveyed object is transferred to the above-mentioned dedicated cart by the loading side transfer device. To receive the conveyed objects by side-shifting the device, the same number of conveying lines and conveying devices as the number of trolleys in the above-mentioned circular predetermined path are required, so the cost increases, occupying expensive factory space, and due to the above-mentioned conveying Due to the space constraints of the line, it may not be possible to meet the demand for increasing the number of trolleys in the above-mentioned circular predetermined path in order to meet the expansion of production.
