In addition, the disposing operation by fitting can be performed stably and quickly with one touch by stably maintaining the assembled posture of the idler rollers 16, 26 and the friction idler rollers 17, 27 and the case body 40. Will be.

When the idle rollers 16, 26 and the friction idle rollers 17, 27 are disengaged from the conveyor frames 12, 22, the case body 40 is moved after the movable locking portion 46 is moved inward against the elasticity. By pulling it upward, it can be done easily and quickly.

Further, the idle rollers 16, 26 with respect to the case body 40 disposed on the conveyor frames 12, 22 are provided.

At the time of operation, that is, at the time of the sorting operation, the conveyed object 5 conveyed on the conveyer line 2 by the conveyer 1 is sorted into a sliding roller conveyor 8 at a predetermined position. 5 can be transported from the curved path 10 to the straight path 20 while sliding.

The sliding on the curved path 10 first slides linearly on the straight path section 10A, and then slides along the curve on the curved path section 10B. A centrifugal force acts on the transferred object 5, and the transferred object 5 tends to move toward the outer path portion.

At this time, since the friction idler rollers 17 are arranged in the outer path portion, the friction idler rollers 17 are moved toward the outer path portion by a sufficient frictional resistance force. The transferred object 5 can be braked, so that the transferred object 5 can be prevented from colliding with the guide body 50 or the side frame portion 13. At this time, since the outer peripheral surface of the friction ring body 33 is formed on the annular uneven surface 34, the above-described braking action is further promoted.

As a result, the transported object 5 slides smoothly on the curved path 10 without colliding with the guide body 50 and the side frame portion 13 and without jumping over the guide body 50 and the side frame portion 13. I can make it. In addition, the curve conveyor section 11 can reduce the width of the path, and can reduce the size and cost of the conveyor.

The shape (size, weight) of the transferred object 5
Some of the transferred objects 5 may come into contact with the guide body 50 or the side frame portion 13 due to a change in the position of entering the curved path 10 or the like.
Since the movement toward the outer path portion side is braked by the group, the contact is performed with a small impact force.

The transported object 5 that has slid on the curved path 10 in this way subsequently enters the linear path 20 and is slid. At this time, the sliding on the straight path 20 is performed while being shifted to one side, that is, the working section 52 side, depending on the direction (inclination) of the idle roller group 26 in both the zones S1 and S2. When the transported object 5 approaches the working unit 52 side sufficiently, since the friction idler rollers 27 are arranged in this path, the friction idlers 27 have sufficient frictional resistance. Thus, the transported object 5 that attempts to move in a direction closer to that can be braked, so that the transported object 5 can be prevented from colliding with the guide body 50 or the side frame portion 23.

The transported object 5 further slid toward the width
Is that the friction idler rollers 27 are arranged so that the roller axis is orthogonal to the direction of the linear path 20,
Together with the braking described above, they will be aligned along the direction of the straight path 20. At this time, since the outer peripheral surface of the friction ring body 33 is formed in the annular uneven surface 34, the above-described braking action and alignment action are further promoted.

The shape (size, weight) of the transferred object 5
A part of the transferred object 5 may come into contact with the guide body 50 or the side frame portion 23 due to a change in the position of entering the linear path 20 or the like.
Since the movement is braked by the group, the contact is made with a small impact force.

The object 5 is brought closer to the working section 52 by the above-mentioned sliding of the object 5 toward the width, and aligned. Therefore, various operations as required by the operator of the operation unit 52 can be suitably performed. For example, the work of taking out the transferred object 5 can be easily performed, the label attached to the side surface of the transferred object 5 and the printed matter can be easily and accurately observed, and the chute 5 of the transferred object 5 can be easily read.
Movement to one side can be easily performed.
