DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the conveyor diverter of the present invention will be described below with reference to the drawings. In the conveyor diverter of the present invention, for example, a paddle 21 as shown in FIG. 1 is attached to the discharger 5 so that even if a load is going to pass through the gap C, the steel belt 1 can be reliably discharged. It is a thing. Therefore, the operation of the diverter of each of the embodiments described later is the same as the operation of the conventional diverter. That is, for example, in FIGS.
The diverter shown in FIG. 1 includes a plate-shaped discharging tool 20 extending along the extending direction of the steel belt 1. One end of the discharging tool 20 in the axial direction is fixed to the rotary shaft 4 and the rotary shaft 4 is rotated about the center of rotation. Drive device 3 between the non-emission position A and the emission position B as
It swings when driven by. 1 and 2, the drive device 3 employs a motor, but the drive device 3 is not limited to the motor, and various types such as an air cylinder may be employed, and the drive device 3 and the rotary shaft 4 are connected to each other. The mechanism is not limited to the illustrated crank mechanism. 1 and 2, members and the like that are the same as or equivalent to the members and the like shown in FIG. 12 are given the same reference numerals.

Discharge tool 2 in the diverter of the first embodiment
0 will be described below mainly with reference to FIGS. 3 and 4.
The discharger 20 is composed of the above-described conventional discharger 5 and a paddle 21 attached to the discharger 5. When the paddle 21 is not attached as in the conventional case, the abutting surface 5a of the discharging tool 5 with which the conveyed goods are brought into contact has gravity at two positions at both ends in the axial direction of the discharging tool 5 over the width W of the discharging tool 5. A guide 22 having, for example, a dovetail shape extending in the direction is fixed by, for example, a screw. The paddle 21 has a width dimension larger than the width W and has a plate shape that covers the entire contact surface 5a of the discharger 5, and has a dovetail groove shape that slidably engages with the guide 22 in the direction of gravity. The engaging portion 23 is formed corresponding to the guide 22.

Such a paddle 21 is attached to the contact surface 5a of the discharging tool 5 by engaging the engaging portion 23 with the guide 22. The paddle 21 attached to the discharger 5 can slide in the gravity direction but cannot move the discharger 5 in the axial direction. Therefore, the paddle 21 is guided by the guide 22 and falls in the direction of gravity due to its own weight, and the end surface 21 of the paddle 21 facing the luggage mounting surface 1a of the steel belt 1 is stopped.
a and the load carrying surface 1a come into contact with each other, and the fall of the paddle 21 is stopped. Therefore, the paddle 21 swings by the drive device 3 together with the discharging tool 5 with respect to the conveyed steel belt 1 while pressingly contacting the luggage mounting surface 1a by its own weight.
Further, even when the steel belt 1 flaps in the direction of the arrow 7, the paddle 21 can move in the gravity direction by following the flap of the steel belt 1 by freely moving in the gravity direction.

Since the end surface 21a of the paddle 21 is constantly in pressure contact with the luggage mounting surface 1a in this way, the material forming the paddle 21 has a small coefficient of friction, a small specific gravity, and an appropriate rigidity. Since it is necessary to satisfy the conditions, the most preferable ultra high molecular weight polyethylene material (UHMW-P
E), MC nylon material having similar properties, polyfluorinated ethylene material generally called Teflon (trademark), and the like can be used. The same material as the paddle 21 may be used for the guide 22.

By attaching such a paddle 21 to the discharging tool 5, the discharging tool 5 and the luggage mounting surface 1a are conventionally interposed through the clearance C, but the paddle 21 is always in pressure contact with the luggage mounting surface 1a. Therefore, even if the load passes through the clearance C or is difficult to fit in the clearance C, the load can be reliably discharged from the steel belt 1 by contacting the load contact surface 21b of the paddle 21 and swinging the discharging tool 20.

Next, a second embodiment will be described. In the above-described first embodiment, the paddle 21 is a single plate-shaped member, and the discharging tool 5 is used.
The discharge tool 30 of this embodiment is formed by dividing the paddle 21 into a plurality of pieces in the axial direction of the discharge tool 5, as shown in FIG.

Two are formed adjacent to each other inside the respective guides 22, but the installation location and number of the springs 41 are not limited to this, and can be changed according to conditions such as pressing force. A spring support tool 43 that supports one end of the spring 41 is fixed to the discharge tool 5 at the end of the opening 42 on the side opposite to the luggage placement surface in the longitudinal direction. On the other hand, the other end of the spring 41 is fixed to the counter contact surface 21c of the paddle 21 via a spring support tool 44.

Since the spring 41 is provided in this manner, the paddle 21 is pressed against the luggage mounting surface 1a by its own weight and the urging force of the spring 41. Therefore, the followability of the paddle 21 with respect to the flapping of the steel belt 1 is improved, the gap between the paddle 21 and the luggage mounting surface 1a is reduced, and the thin luggage is more reliably wiped from the steel belt 1. Can be issued.

Further, if there is a sufficient space for installing the spring 41, the spring 41 may be provided in each paddle 31 in the second embodiment.
With such a configuration, even when unevenness locally occurs on the steel belt 1, the paddle 31 can more reliably follow the unevenness, and the paddle 31 and the load carrying surface 1a are prevented from moving. The occurrence of a gap is reduced, and a thin load can be reliably discharged from the steel belt 1.
