Abstract

(57) [Summary] (Corrected) [Purpose] Providing a reverse conveyor line unit on a belt conveyor that conveys in a fixed direction, and provides a simple conveyor that can convey in both forward and reverse directions with a single conveyor. To do. [Structure] The unit of the reverse conveying line includes a roller 21 and frames 22 and 23, which are hollow pipes and are freely rotatable.
So that the side plates 24 and 25 support each other.
Is screwed to the frames 22 and 23. A piano wire 26 for connecting the units to each other is provided at one end of the unit. Notches 27 are provided at both ends of the frame 22, and are fixed to a line for fixing the unit with a string so that the unit does not flow on the belt conveyor. The roller 21 absorbs the vertical fluctuations of the belt of the belt conveyor and rotates, so that reverse conveyance is possible.

[Industrial applications]

 The present invention relates to a conveyor, and more specifically, to a conveyor that can convey an item in the opposite direction by using a belt conveyer that conveys in a certain direction.

[0002]

[Prior art]

 With conventional conveyors, when goods are conveyed in the reverse direction, the conveyor can be rotated in the reverse direction, another conveyor that can be conveyed in the reverse direction can be provided, or the conveyor itself can be looped. Had to take. However, if the conveyor is conveyed in the reverse direction, the work in the forward direction must be interrupted, and if another conveyor for conveying in the reverse direction is provided, the capital investment will be too expensive and the looped conveyor will be used. However, there is still a problem that the equipment will be large even if it is installed. Therefore, the present invention provides a simple conveyor that can be transported in both forward and reverse directions with one conveyor by providing a portion that can be transported in the opposite direction using the same conveyor that transports in one direction. is there.

【Example】

 FIG. 1 is an overview of the device of the present invention. In the figure, 10 is a well-known belt conveyor, which advances in the direction of the arrow. Reference numeral 20 is a reverse conveying line of the present invention, which conveys in a direction opposite to the direction of the arrow. FIG. 2 is an assembly drawing of a unit of the reverse conveying line. As shown in the figure, the rollers 21 made of hollow pipes and the frames 22, 23 are sandwiched between the side plates 24, 25 made by bending an iron plate into an L-shape so that both side plates are made by the frames 22, 23. Screw it in. A piano wire 26 for connecting the units is provided at one end of the unit. Notches 27 are provided at both ends of the frame fitting 22. As shown in FIG. 1, the notch portion 27 is for fixing with a cord to the fixing wire 11 so as not to flow on the belt conveyor 10. In FIG. 2, reference numeral 28 is a protrusion (a tapping screw is used in the present invention) for preventing the roller from flowing, and its diameter is smaller than the diameter of the hollow portion of the hollow pipe 21. This is because the vertical movement of the belt of the belt conveyor is absorbed and all the rollers rotate as shown in the cross-sectional view of FIG. 3, but a hollow pipe is used as shown in FIG. Alternatively, the screw may be rotated about the center of the roller. The heights of the side plates 24 and 25 are higher than that of the roller 21 so that the conveyed product does not fall from the rollers. Also, considering the case where the belt 10 comes into contact with the side plates, the lower ends of the side plates 24 and 25 are coated with Teflon-treated resin 29 to reduce the friction, but a small pulley may be provided.

When extending the line for reverse transport, a similar transport unit is prepared, and the notch 27 of the frame 22 is hooked on the piano wire of the transport unit at the preceding stage to be locked. In the same way, several pieces are connected and used. In the present embodiment, the case where the cutout portion provided in the frame is used as the locking piece and the piano wire is used as the locked piece has been described, but it goes without saying that the invention is not limited to this.

【effect】

 According to the present invention, one belt conveyor can be provided with a line that can be conveyed in the opposite direction, and the same belt conveyor is used to return the material and jig to the previous process against the flow of the belt conveyor. It is possible to effectively use the production line, and it is possible to significantly increase the production capacity with a simple method.
