Claims (1)

[Claims for Utility Model Registration] (1) A plurality of shape-retaining rollers are arranged by disposing a plurality of support devices pivoted on substantially the same circumference at appropriate intervals, and passing the rollers through a rounding device. An endless belt rolled into a pipe shape is rolled out flat at two drums, front and back, which are spaced apart from each other. In a pipe conveyor that transports objects by passing them through the device, on the return journey, (a) a pipe is formed by rolling upwards both ends of the returning belt, which is folded back from the end of the conveyor's outgoing journey and unfolded flat; (b) A rounding device arranged in parallel at a predetermined interval in the traveling direction of the belt and abutting on the outer circumferential surface of the pipe-shaped return belt at an angle in the same direction as the tangential direction; (c) a twisting device that gradually twists the return belt by 180 degrees around the longitudinal axis of the belt so that the overlapping side end thereof is placed upward while maintaining the pipe shape; (c) located above the pipe-shaped return belt; an opening device that forcibly opens the overlapping side end at a certain angle; (d) an object supply device installed directly above the opening device that supplies the object to be transported to the opening of the returning belt; and (e) an opening. (f) a support device similar to that used in the outward path of the conveyor, which allows the pipe-shaped return belt wrapped around the conveyed object to pass through the conveyor belt while maintaining its shape for a predetermined distance; , (g) a first unfolding device that unfolds the pipe-shaped homeward belt flatly; (h) a conveyed object discharge device that discharges the conveyed object on the flatly expanded homeward belt; (i) the conveyed object. (j) a rounding device that rolls up both ends of the flat return belt which has been discharged and becomes empty into a pipe shape; A twisting device that gradually twists the belt by 180 degrees around the axis in the traveling direction so as to move downward, and a second unfolding device that unfolds the returning belt whose overlapping side end is located downward into a flat state. A reciprocating pipe conveyor characterized by the following: (2) A torsion roller is attached to the pivot piece of a pivot fitting consisting of a base piece and a pair of pivot pieces that are connected in parallel to each other in a direction perpendicular to the base piece at both ends of the base piece. is pivotally mounted, and the base piece is attached to a support device on which the pipe-shaped return belt runs, with a twisting roller device capable of adjusting the inclination angle of the twisting roller in a direction perpendicular to the traveling direction of the return belt. A reciprocating pipe conveyor according to claim (1) of the utility model registration claim. (3) Hold the torsion roller with the bolt and nut,
Utility model registration claim No. 2, characterized in that the tilt angle is adjustable and attached to a support device.
The reciprocating pipe conveyor described in ). (4) An inclination angle adjustment lever is integrally attached to the base piece of the pivot fitting of the torsion roller, and the inclination angle of the torsion roller can be adjusted using the inclination angle adjustment lever. A reciprocating pipe conveyor according to claim (2) of the utility model registration claim.
