Description

[Detailed description of the invention] "Purpose of invention" a　Industrial use portion The present invention relates to a belt conveyor with a curved conveyance path.

b. Conventional technology None cannot be reciprocated.

"Structure of the Invention" a Means for Solving the Problems The upper end of the diagonal roll is diagonally disposed below the horizontal roll or the rubbing member in close proximity to the outer end of the horizontal roll or the rubbing member. By forming a pair of roll units, an endless conveyor belt is hung in a U-shape over a horizontal roll or a sliding member and an oblique roll, and by arranging multiple roll units at bends in the conveyor line, continuous conveyor belts are formed. An object of the present invention is to provide a belt conveyor having a conveyance path that is flexible and bends freely, and conveys a workpiece in an arbitrary direction.

b Effects and Examples According to the invention, therefore, the conveyor belt box, f
At the bending point of the belt, the conveyor belt is pulled down to the lower diagonal roll while rubbing against one horizontal roll or rubbing member, and the conveyor belt is pulled up toward the other horizontal roll or sliding member to advance the conveyor belt. The gap between the upper pair of horizontal rolls or sliding members is almost filled by the thickness of the conveyor belt that is lowered and the conveyor belt that is pulled up, and the workpiece is almost level-shifted. This allows it to pass through bends without any hindrance in a stable manner.

Below, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in Figures to Figure 5, the corners of the frame-shaped frame fil at the end of one conveyor line are cut out diagonally by 6 degrees to form roll pivot walls (la) (1a), and each roll Another roll pivot wall (1b) made of K angle material of the frame (1) is vertically pitched and fixed to the pivot wall (1a). A U-shaped cut is made in the upper part of each roll receiving and receiving wall (1a), and the cut is bent outward to form one bearing (2), and a roll pivot wall ( 1a), two bearings +3+ +3+ are placed horizontally side by side at a predetermined interval, and a parallel line is cut upward from the lower end face of the other roll support wall (1b). The bearing, 2) is bent in the same direction as the bending direction of the wall serving as one part to form two bearings (2a) (2a), and the two wall soil parts of the roll pivot wall (1b) are bent as described above. Each bearing (3
), four bearings (3a) facing each other are installed in parallel. By mounting the diagonal roll (4) diagonally across the bearings (2) and (2a), and arranging the horizontal rolls t51 +5+... in parallel across the bearings (3) (3a) with a gap G maintained. Form a roll unit. horizontal roll i5)
K As another alternative embodiment, as shown in FIG. 3, a cross-sectional sliding member (6) is formed, and the rounded sides are opposed to each other, and the roll unit is arranged in parallel with a gap G maintained. As an example of a pond with a single diagonal roll, the central axis of a conical roll (4a) is tilted and the shaft is supported by bearings (2) and (2a), as shown in Fig. 4. As shown in FIGS. 6 and 7, an endless conveyor belt (7) traveling from direction A is placed at both ends of the conveyor line, and the rubbing members (6) are bent in a dogleg shape. Another sliding member (6a) having a shape is guided by one oblique side and folded in half at right angles and downwards, and then guided by the other oblique side and folded in half at right angles and upwards, 180 degrees in direction B. It is also possible to use a belt conveyor with a conveying path for switching and advancing, in which case the conveyor belt (7
) is provided at a position directly above the baffle plate (8) with a slight interval between the baffle plates (8) and the workpieces conveyed from direction A to the baffle plate (18+).
It is possible to transfer the robot to the conveyance path in the direction B. Also, as shown in Figure 8, there are two conveyor belts extending over horizontal rolls (5) (5)! 7++7! Two diagonal rolls (not shown) are provided independently below the horizontal roll tel j51 in order to run the conveyor line back and forth. The conveyor belt (7) traveling from the A direction is rotated by a -degree angle to run in the A' direction, then turned 180 degrees in the B direction, and further applied in the B' direction. One conveyor belt (
1) is circulated back and forth in the input direction and B' direction,
The conveyor belt (1) is a device for which the applicant previously applied for a patent (Japanese Patent Application No. 57-196410), which allows the conveyor line to be extended and contracted and to be easily laid. For installation, use the box (9
), and then the conveyor belt (1) is loosened and sent out. Further, as shown in Fig. 9, the angle formed by the respective axes of the pair of horizontal rolls +5) i5) is maintained at an acute angle, and the angle of inclination of each diagonal roll (4) is made shallow, that is, an appropriate angle approaching the horizontal line is maintained. By forming the roll units held at an inclination in multiple stages, the conveyor belt (7) can be circulated in a polygonal or circular direction. In addition, in FIG. 1, by installing one roll unit, the conveyor line can be rotated by (a) degrees.

"Effects of the Invention" Since the present invention is constructed in this manner, the conveyor belt (1
) is freely rotated in any direction by a roll unit consisting of a pair of horizontal rolls i5 +5) and an oblique roll (4) provided diagonally below the horizontal roll (5), A desired conveyor line can be formed simply and easily. When a large number of roll units in which the tilt angle of the diagonal rolls (4) is shallow are arranged, the conveyor line can be formed into a shape close to a circle. At each bend in the conveyor line, the conveyor belt (7
) is the gap G formed between the horizontal rolls L51 +51
Since the surface of the conveyor belt (7) is always facing upward, the workpiece is reliably transferred onto the conveyor belt (7) running in a different direction at the bending point, and the workpiece can be transferred to the conveyor belt (7) running in a different direction at the bending point. There is no risk of collision due to traffic congestion, and the workpiece can be smoothly transferred onto the conveyor belt (1) running in a different direction without causing shock, so there is no risk of the workpiece falling over in a standing state. This ensures stable transportation.

As described above, the present invention is an excellent and useful invention that has a robust structure, no failures, reliable operation, and is easy to manufacture.
