Japanese Patent No. 3894750

  The configuration of the conveyor device described above is significant in that the belt tension can be easily adjusted while realizing simplification and downsizing of the structure. However, in this configuration, assuming that the driven pulley is moved in the longitudinal direction of the side frame when adjusting the belt tension, the bearing fixing plate must be provided with a notch portion having a sufficient length. It was necessary to make the length of the bearing larger than the width of the bearing. Therefore, in order to avoid contact with the drive pulley of the adjacent conveyor device, there is room for improvement in that the interval between the conveyor devices must be increased.

  In addition, the pressing force from the positioning bolt and the tension from the belt are mainly applied to the bearing, but in the conventional configuration, the direction of the fixing bolt screwed into the bearing fixing plate is relative to the direction of these forces. There was a problem of crossing. Therefore, in order to prevent damage to the bearing, there is room for improvement in that the strength of the bearing must be ensured.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a conveyor device that can reduce the interval between devices and can prevent damage to bearings.

In this conveyor apparatus, the bearing is fixed to the end surface of the side frame in a state where the support member faces the end surface of the side frame. This reduces the amount of protrusion of the base plate from the end face of the side frame, as compared to the conventional configuration in which the bearing is fixed to the bearing fixing plate that protrudes from the end face of the side frame. It becomes possible. Therefore, the space | interval between adjacent conveyor apparatuses can be narrowed. Further, in this conveyor device, the direction of the pressing force from the positioning bolt acting on the bearing, the direction of the tension from the belt, and the direction of the fixing bolt are all in the longitudinal direction of the side frame. It is possible to prevent excessive force from being applied. Therefore, damage to the bearing can be prevented.

Moreover, it is preferable that the support member is provided with a stopper that is provided so as to project to the bearing side and that contacts the support member and the base plate . Thereby, since a support member and a base plate contact | abut with sufficient area, a bearing can slide stably along a base plate. Further, since the stability of the bearing on the base plate is increased, the workability when adjusting the belt tension can be improved.

In addition, a predetermined number of shims are arranged between the head of the fixing bolt and the end surface of the side frame and between the end surface of the side frame and the support member . It is preferable to have a notch through which at least the bolt can be inserted . In this case, since the shim can be stored near the bearing, the shim can be prevented from being lost. Further, when adjusting the belt tension, the number of shims arranged between the head of the fixing bolt and the end face of the side frame, the end face of the side frame, and the support member are not changed without changing the total number of shims. By changing the number of shims arranged between them, it is not necessary to change the length of the fixing bolt.
