In addition, a support roller 14 that is fitted into a support rail 13 provided along the movement path 2 and rolls in the support rail 13 is provided on one side of each transport body 1.

A belt conveyor 16 for discharging the load 15 to the rear in the moving direction A of the carrier 1 is provided above the respective carriers 1. As shown in FIGS. 1 and 2, the belt conveyor 16 includes a pair of front and rear idler rollers 17a and 17b opposed in the direction of the movement path 2, and both idler rollers 17a and 17b.
A belt 18 (an example of an endless rotating body) that is wound between and supports and transports the load 15, and a rotating shaft 19 that is integrally provided at both ends of the idle rollers 17 a and 17 b via a bearing 20. It comprises a pair of left and right conveyor frames 21 which are freely rotatably supported. On one side of the back of the belt 18, a belt
A projection 22 for preventing the meandering of 18 is formed over the entire circumference, and the projection 22 is engaged with a groove 23 formed over the entire circumference of the idle rollers 17a and 17b.

On the other side of the surface of the belt 18,
A large number of engaged projections 26 (an example of an engaged body) are provided at predetermined intervals over the entire circumference of the belt 18. Further, at a plurality of sorting positions 28 set on the upper linear path portion 2a of the moving path 2, there are provided engaging protrusions 29 (which can be disengaged from the engaged protrusions 26 in the moving direction A of the carrier 1). Engaging body) is provided. The three engaging projections 29 are provided on the lifting block 31 which is raised and lowered by the air cylinder 30 and the like in the direction of the movement path 2. The elevating block 31 moves up and down between an engaging position A where the engaging protrusion 29 engages with the engaged protrusion 26 and a retracting position B where the engaging protrusion 29 is disengaged from the engaged protrusion 26.

As shown in FIG. 2, the outer side surface of the conveyor frame 21 on one side has a smaller force than the engaging force between the engaging projection 29 and the engaged projection 26, so that the moving path 2 A brake torque limiter 32 (an example of a brake device) that regulates the rotation of the rotating shaft 19 of the front idler roller 17a in the direction is provided. The brake torque limiter 32 is
When a torque equal to or more than a predetermined value is generated in the front idler roller 17a in the direction of the movement path 2, the rotation shaft 19 of the idler roller 17a is unlocked. The predetermined value of the torque is set to be equal to or less than the torque generated in the idle roller 17a when the engaging projection 29 and the engaged projection 26 are engaged.

A plurality of protrusions 33 are formed on the surface of the belt 18 to prevent the load 15 from dropping and to push the load 15 out in the width direction. As shown in FIGS. 3 and 4,
On the table 34 provided on the support frame 8, a plurality of receiving boxes 35 for receiving the load 15 discharged and dropped from each carrier 1 are arranged.

The operation of the above configuration will be described below.
The plurality of connected traveling bodies 3 are driven by the linear motor 12.
The vehicle travels while being supported and guided by the traveling rails 5 and 6 via the wheels 4, whereby each transport body 1 moves on the moving path 2,
The load 15 placed on the belt conveyor 16 is transported on the movement path 2 by the movement of the transport body 1.

At this time, as shown in FIG. 2, since the brake torque limiter 32 regulates the rotation of the rotating shaft 19 of the front idler roller 17a, the belt 18 of the belt conveyor 16 is fixed, and It does not rotate easily. Also, as shown in FIG. 1, the load 15 is a pair of front and rear protrusions on the movement route 2.
Since the load 15 is placed on the belt conveyor 16 between the positions 33, the load 15 can be prevented from dropping to the front and rear of the belt conveyor 16.

When the load 15 reaches the target sorting position 28, as shown in FIG. 6, the air cylinder 30 is actuated, and the elevating block 31 is lowered to the engagement position A, and the engagement protrusion 29 Engages with the engaged projection 26 from above, and the transport body 1 further moves in this state. With the movement of the carrier 1,

With the movement of the conveyor 1, the belt 18 rotates in the direction of arrow B and the idle rollers 17a and 17b also rotate, so that the load 15 is discharged to the rear of the belt conveyor 16 as shown in FIG. As shown in FIGS. 10 and 11, it is received in a predetermined receiving box 35 and sorted.

At this time, as the belt 18 rotates, the belt 18
Even if the surface of the sheet 15 slips with respect to the load 15, the front protrusion 50a on the loading side S forcibly pushes the load 15 to the rear of the belt conveyor 16, so that the load 15 is reliably discharged.

As described above, since an electric motor for driving the belt conveyor 16 which has been conventionally required for each transport body 1 is no longer required, a power supply device such as a power supply rail or a current collector is not required, and the cost is reduced. In addition, the structure can be simplified.

After the load 15 has been delivered to the rear of the belt conveyor 16, when the front engaged roller 42a reaches the rear end of the belt conveyor 16, as shown in FIG. The piece 49 rotates from the engagement position A, switches to the retreat position B, separates from the engaged roller 42a, and forms a part of the guide rail 40. As a result, as shown in FIG. 10, the empty carrier 1 moves from the upper straight path section 2a of the moving path 2 to the lower linear path section 2b via one arcuate path section 2d.

As shown in FIG. 13, when the front engaged roller 42a reaches the rear end of the belt conveyor 16 due to the rotation of the belt 18, the rear engaged roller 42b The belt 16 moves from the rear end of the conveyor 16 to the front and rear intermediate portion on the opposite side to the loading side S, and the remaining engaged rollers 42c are moved from the front and rear intermediate portion on the opposite side of the loading side S of the belt conveyor 16 to the belt conveyor. To move to the front end of the belt conveyor 16, the engaged rollers 42a, 42b, and 42c always stand by at the front and rear ends of the belt conveyor 16 and at the front and rear intermediate portions opposite to the loading side S, respectively.
