Roller chain conveyors, which convey various raw materials, intermediate products, and final products, have rollers rotatably held on a spindle that connects a pair of left and right link plates, and many of these are connected in a chain. The link plate is driven at the required speed by placing the conveyed object on it.

よう小ローラ２を嵌め込んだものがある。 As a roller chain conveyor like this,
For example, as shown in FIG. 3, the front and rear portions of a pair of left and right inner plates 5' are fixed at a constant interval by bushings 6, and a pin 1 is rotatably inserted into each bushing 6. At both ends of 1, the front and rear parts of a pair of outer plates 5'' are rotatably held, linking a large number of inner and outer plates in a chain, and on the other hand, there is a bush 6 and a pin 1 inserted therein. is the supporting shaft, and the large outer diameter cylindrical part 3 is attached to this.
b and a small outer diameter cylindrical portion 3 integrally formed on both sides thereof.
A large roller 3 consisting of a is rotatably mounted, and a small roller 2 is mounted on the outer peripheral surface of the small outer diameter cylindrical portion 3a so as to be rotatable between the inner surface of the inner plate 5' and the side surface of the large outer diameter cylindrical portion 3b. There are some that have been fitted.

る。 According to such roller chain conveyor,
When a conveyed object (not shown) is loaded onto the large roller 3, the inner circumferential surface of the small roller 2 rotating in contact with the rail 4 comes into pressure contact with the outer circumferential surface of the small outer diameter cylindrical portion 3a, and its rotational force is transmitted to the large roller 3, so the large roller 3 rotates according to the diameter ratio of the large outer diameter cylindrical portion 3b and the small roller 3a, and conveyance can be performed at a speed faster than the advancing speed of the link plate 5. Also, when the conveyed object is forcibly stopped temporarily, the large roller 3 is moved to the small roller 2.
Since the conveyed object overcomes the rotational frictional force with the large roller 3 and comes to a standstill, the conveyed object can be stopped without being rubbed on the large roller 3.

A large roller 16 is sandwiched between the pins 12 via a friction plate 15, and a nut 17 is attached to the threaded portion of the pin 13 via a compression spring S. According to this brake roller, the sides of the large roller 16 are held between the two friction plates 15 by the repulsive force of the compression spring S, so the large roller 16
The rotational force of is regulated by frictional force.

However, such a brake roller has a problem that the position of the large roller 16 with respect to the rail 10 and other structures are completely different from those of the roller chain conveyor (see FIG. 3), so that they cannot be used in combination. Also, this brake roller has large rollers 16 on both sides of the rail 10.
The conveyor has a structure in which the pins 13 and 13 protrude greatly, and it is necessary to cover almost the entire conveyor with a storage frame (not shown) in consideration of safety during use, which increases the size of the conveyor and makes it difficult to use in a narrow space. There is a problem that.

The brake roller according to the present invention configured as described above has a compact structure in which small rollers are arranged on both sides of a large roller, and since the small rollers rotate freely, it is movable on the rail. The elastic force of the spring causes the dividing surfaces of the large roller to separate in the axial direction, so the outer surface of the small outer diameter cylindrical portion of the large roller comes into pressure contact with the inner surface of the link plate, and the frictional force prevents the rotation of the large roller. Regulated. Therefore, the inertial force acting on the conveyed object on the large roller is absorbed by the large roller, and the conveyed object can respond well to the movement of the link plate.
