As shown in FIGS. 5 and 10, on both sides of the main body frame 1, branch conveyors 54A, 53B forming branch paths 53A, 53B inclined outward and downward with respect to the main transport path 21. 54B
Is provided. Here, the branch conveyors 54A and 54B have a large number of rollers 55, and the ends of these rollers 55 are located in the step 2c of the upper frame material 2 and in a state where they are sufficiently close to the vertical members 2a. Be placed. The outward dovetail groove 7d of the upper frame member 2 can be used for connection with the branch conveyors 54A and 54B. 56 indicates an article.

When assembling the movable body 60, first, a pair of rubber bodies 62 are set on the shoe body 61. This can be performed by fitting the rubber body 62 into the through portion 66 from the side. The fitting is performed until the outside of the rubber body 62 comes into contact with the side surface of the shoe main body 61, and at this time, the vertical groove 74 is fitted to the vertical piece 67 or the horizontal piece 68, whereby the rubber body 62 is It is positioned between the outer periphery and the center. Further, in the rubber body 62, the vertical hole 75 matches the through hole 72, and the horizontal groove 74 is exposed inside. Next, the cover body 63 is set so as to cover the front and upper surfaces of the shoe main body 61. This set includes an engagement piece
This can be achieved by engaging the locking hole 70 with the locking hole 70 against elasticity.In this case, the vertical piece 77 engages with the horizontal groove 74 from above, and the fitting portion 78 passes through the vertical hole 76. By fitting into the through hole 72, the rubber body 62 is prevented from coming off.

Next, the operation of conveying and branching the article 56 in the above embodiment will be described.

By driving the electric motor 13 of the driving device 12 and rotating the hollow shaft of the speed reducer 14, the sprocket 17 is forcibly rotated via the driving shaft 11 fitted inside the hollow shaft, thereby
The guide rail 19 can be moved by being supported and guided by guide rails 22 and 23.
Accordingly, the group of rollers 20 circulates, so that the article 56 supplied on the roller 20 at the start end is conveyed on the main conveyance path 21. At this time, the movable body 60 that moves integrally with the roller 20 group is
By being guided by 0, 40, it reciprocates in the width direction via the sliding guide portion 69, or moves linearly along the main transport path 21.

That is, for example, the guide roller 64 guided by the one-side starting end guide portion 31A is guided straight when the sorting device 52A is in the linear sorting posture, and straightly moves without receiving the guiding action, and thereafter the end guide portion 34A Will be guided to. As a result, the movable body 60 does not act on the article 56, and the article 56 is transported in a straight line on the main transport path 21. The same applies to the opposite side, and the guide roller 64 of the starting end guide portion 31B is moved from the sorting device 52B to the end guide portion 3B.
It will move to 4B.

The guide roller 64 guided by the one-side starting end guide portion 31A is guided inclining inward when the distribution device 52A is in the inclined distribution posture, and is moved inward by being guided by the inward movement guide portion 32A. , Upper switching device 50
The outer moving guide 33B moves to the outer moving guide 33B, and is moved outward by being guided by the outer moving guide 33B.
You will be guided to 4B. With this, the movable body 60 group,
While moving in the transport direction, it crosses the main transport path 21, thereby laterally pressing the article 56 via the friction contact surface 72, and passing the article 56 to the outer branch conveyor 87B. . The same applies to the opposite side, and the starting end guide portion 31
The guide roller 64 of B is guided by the sorting device 52B, the inner moving guide portion 32B, the upper switching device 50, the outer moving guide portion 33A, and the terminal guide portion 34A, and passes the article 56 to the branch conveyor 54A. At this time, the article 56 on the roller 20 is
It climbs over the upright section 2a supporting 19 and then rides on the roller 55 located on the step 2c.

The roller 20, which has reached the ends of the end guide portions 34A, 34B as described above, is guided by the ring bodies 48A, 48B, reverses, and is guided by the inner moving guide portions 41A, 41B to be moved to the center of the width. You. After being distributed to the left and right by the lower switching device 51 (to be described later), it is moved outward by the guidance of the outer moving guides 42A and 42B, and then guided by the wheels 47A and 47B to be inverted, and then to the starting end guide. Moved to either 31A or 31B.

In the above embodiment, the upper frame material 2 and the lower frame material 3
However, the lower frame material 3 may be a side plate or a side frame.

Effects of the Invention According to the present invention having the above-described configuration, assembly of the movable body can be easily performed by fitting the rubber body to the shoe body from the side and then mounting the cover body to the shoe body from above. And can be easily performed. At this time, the rubber body can be positioned in the horizontal, vertical and horizontal directions by fitting and abutting on the shoe body, and the rubber body comes off by fitting the fitting part of the cover from above. Stopping can be performed, so that it can be firmly fixed to the shoe body side.
