ローラーとの間に設けられる伝動機構の改良に関

収する必要があつた。(B) Prior Art In a roller conveyor device, rotational force is transmitted from a drive shaft to each roller using a belt. However, in a belt drive device, when an excessive load is placed on the driven roller or an action is taken to stop its rotation, a tension exceeding a predetermined value is generated in the belt. In this situation, it was necessary to absorb the excess tension somewhere in the transmission mechanism.

過大張力を吸収する構成（特公昭49−45836号公
報）が知られている。 As a conventional technique, a configuration is known in which a transmission belt simply rotates idly between a pulley or roller of a drive shaft to absorb the excessive tension.
In addition, as an improved device for this configuration, the drive shaft and pulley are not fixedly attached, but a small gap is created between the shaft and the pulley, and as a result, it is necessary to drive the individual rollers linked to the pulley. There is a known structure (Japanese Patent Publication No. 49-45836) in which each pulley slides when the torque exceeds a predetermined value to absorb the excessive tension.

いという欠点があつた。(c) Problems to be solved by this invention The conventional method of simply installing a transmission belt between a pulley and a roller with an appropriate tension has the disadvantage that the friction force is strong when the transmission belt spins idly, resulting in severe wear of the transmission belt. Ta. In addition, if a small gap is provided between the drive shaft and the pulley, the tension of the transmission belt must be relatively strong, resulting in a short belt life.

The drive shaft 3 is entirely formed so that its cross section is partially circular, and is rotated by a motor 8. Reference numeral 4 denotes a pulley, and the shape of the central hole into which the drive shaft 3 fits is the same as the cross section of the drive shaft 3 . The pulley 4 is provided under each driven roller 1, and a transmission belt 6 is mounted between the pulley 4 and the groove 5 of each driven roller 1. The transmission belt 6 is an endless belt made of an elastic material, and one end is attached to the pulley 4, and the other end is twisted at an appropriate angle and attached to the groove 5 of the driven roller 1. The transmission belt 6 has a sliding portion 7 having a smaller coefficient of friction than the main body of the transmission belt 6 over a length of at least 1/2 or more of the circumference of the pulley 4 in a part thereof.

ある。(E) Function The roller conveyor device rotates a drive shaft 3 using a motor, and rotates each driven roller 1 at a constant speed via a large number of pulleys 4 and a transmission belt 6 on the drive shaft 3. At this time, the rotation of the drive shaft 3 is the same as the rotation speed of the pulley 4 and the driven roller 1.

常な状態にもどると伝動ベルト６は再びプーリー
４と被動ローラー１との間を回り始める。 When the rotation of the driven roller 1 stops due to an excessive load encountered during work, the sliding portion 7 of the transmission belt 6 comes to the position of the pulley 4, and the transmission belt 6 moves approximately 1/1/2 of the way from the pulley 4.
When the transmission belt 6 is wrapped around two circumferences, the pulley 4 and the sliding portion 7 of the transmission belt 6 slip, and the transmission belt 6 becomes in a slip state and stops rotating. Further, when the load on the driven roller 1 returns to a normal state, the transmission belt 6 starts rotating between the pulley 4 and the driven roller 1 again.

吹付け等で設けてもよい。(F) Embodiment A roller conveyor device has a large number of driven rollers 1 rotatably installed on a conveyor rail 2, and a drive shaft 3 is provided below the driven rollers 1 along the moving direction of the cargo. The drive shaft 3 is entirely formed so that its cross section is partially circular, and is rotated by a motor 8. Reference numeral 4 denotes a pulley, and the shape of the central hole into which the drive shaft 3 fits is the same as the cross section of the drive shaft 3 . The pulley 4 is provided under each driven roller 1, and a transmission belt 6 is mounted between the pulley 4 and the groove 5 of each driven roller 1. The transmission belt 6 is an endless belt made of an elastic material, and one end is attached to the pulley 4, and the other end is twisted at an appropriate angle and attached to the groove 5 of the driven roller 1. This angle is 90° for straight sections of the conveyor, and an appropriate angle within 90° for curved sections. The transmission belt 6 is formed of an annular round rope, and a steel coil spring 7 is wound around a part of the rope. The length of this coil spring 7 is configured to be at least 1/2 or more of the circumferential length of the pulley 4. As another embodiment, a material having a coefficient of friction smaller than that of the material of the main body of the power transmission belt 6 may be provided by pasting or spraying.
