Conveying Machine Device

Abstract

The invention provides a conveying machine device. A support frame (1) is composed of a plurality of connection rods connecting a plurality of carts in a rotary manner. The carts can move with the guidance of a guide rail (10) arranged along the conveying path (A) and can separate in the conveying direction (E). A continuous to-be-fricated face (A) is formed on the outer surface of the cart and the connection rods, covering the conveying direction (E). In a downstream inclined path part (B), forceless braking components (B1, B2) pressing a friction roll(2) on the to-be-fricated face (1A). At the same time, the support frame (1) is made move automaticaly through gravity. A high position horizontal path part (C1) more adjacent to the upstream side than the downstream inclined path and a low-position horizontal path part (C2) that is more adjacent to the downstream side than the downstream inclined path (B). The support frame (10) is driven through power at the same time that the driving roll (7) is pressed on the to-be-fricated face (1A).

Description

technical field [0001] The present invention relates to a conveyor device for moving a carriage along a conveyance path including a descending inclined path portion, and more particularly to a conveyor for automatically traveling the carriage by gravity without using a drive device in the descending inclined path portion device. Background technique [0002] On a production line for conveying objects with a relatively large shape and weight, such as automobiles, a conveyor device that transports the pallets on which the above-mentioned objects can move along the guide rails is used, on a relatively steep inclined path The conveyance of the above-mentioned bracket generally uses the accumulation type trolley conveyor (for example, refer to the [ 0011], [0033] and [0056]) [0003] In addition, in order to achieve cost reduction and space saving, there is a device that automatically travels the carriage by gravity without using a drive device in the downward inclined path por...

AI Technical Summary

Problems solved by technology

[0006] Although the above-mentioned product-and-free trolley conveyor can transport the above-mentioned brackets along a relatively steep inclined path, on the opposite side, it is composed of a power transmission chain, a power trolley, a trolley rail guiding the power trolley, a tensioning part, a large-diameter A large-scale device composed of a driving sprocket and a driven sprocket, etc., so the manufacturing cost and installation space increase (for example, refer to paragraph [0036] of Patent Document 1)

[0007] On the other hand, the conveyor device of Patent Document 2 can automatically run the carriage by gravity along the conveyance path including the descending inclined path portion without using a driving device, so that cost reduction and space saving can be realized. On the other hand, even when there is no need to store the pallets in the downward inclined path, and the pallets are only conveyed from a higher conveying height to a lower conveying height, the pallets are repeatedly accelerated and decelerated. Since it moves while moving, there is a disadvantage that the deceleration operation time is insufficient in the downward slope path part with a steep angle, and it is difficult to maintain the carriage at a constant speed.
