By appropriately moving the accumulation conveyor 47 up and down, it can be opposed to the transport conveyor 1 or the gate conveyor 48 so as to be close to and lined up in series.

Next, the operation of the branching conveyance device of the above embodiment will be explained.

Next, the operation of the refractive conveyance device having the branching device will be explained.

Baggage 49 transported by gate conveyor 48
is supplied to the accumulation conveyor 47, and then from the accumulation conveyor 47 to the conveyor 1
is supplied to

As shown in FIGS. 1 to 3, the branching truck 2 is stopped at a position where the movable chute 24 is lined up in series between the relay chute 22 and the chute 25,
and tilting the branch conveyor 4 so that its distal end is located upstream of the conveyor rather than its proximal end;
When the conveyor belt 21 of the transport conveyor 1 and the conveyor belt 14 of the branch conveyor 4 are driven in circulation in the direction of the arrow, the cargo conveyed by the transport conveyor 1 is received by the branch conveyor 4, and the branch conveyor 4 transfers it to one of the relays. It is supplied to the movable chute 24 via the chute 22, and then slides on the movable chute 24 and one branch supply chute 25 to be transferred to the branch conveyor 41.
Alternatively, it is supplied to the baggage receiving department, etc.

Furthermore, as shown in FIG.
is disposed above the downstream end of the transfer conveyor in the relay chute 23, and in this state, when the conveyor belt 14 of the branch conveyor 4 is circulated in the direction of the arrow, the cargo conveyed by the transfer conveyor 1 is transferred to the branch conveyor. 4, and is supplied by the branch conveyor 4 to the other branch supply chute 26 via another relay chute 23, and then slides on the chute 26 and is supplied to the branch conveyor 41 or the baggage receiving section, etc. be done.

When carrying out this invention, a swing drive device consisting of a worm and a worm wheel rotated by an electric motor with a speed reducer may be used as the switching drive device 5.

In the case of the above embodiment, the storage conveyor 47
can receive the baggage 49 from the gate conveyor 48, so that the baggage conveyance efficiency can be improved.

According to this invention, one end of the branching conveyor 4, which is cyclically driven in the forward and reverse directions by the branching conveyor drive device 3, is attached to the branching cart 2 that runs along the side of the conveyor 1, with the branching conveyor 4 centered on the vertical axis. The branching conveyor 4 is rotatably attached to the top surface of the conveyor 1, and the branching conveyor 4 is arranged at a slightly higher level than the upper surface of the conveyor 1. Since a switching drive device 5 is provided for
This is a simple process in which the branching cart 2 is stopped at an appropriate position in the longitudinal direction of the conveyor 1, the branching conveyor 4 is tilted forward or backward in the longitudinal direction of the conveyor, and the branching conveyor 4 is driven to circulate in one direction or the other. By performing this operation, it is possible to branch and convey the cargo, which is conveyed by the conveyor 1 from the rear to the front, in any direction to the left or right of the conveyor 1 at any position in the longitudinal direction of the conveyor 1. , and the cargo can be continuously branched and conveyed at arbitrary positions. In particular, in the case of the present invention, the conveyor 1 can be moved up and down by a lifting drive device, and the width direction of the conveyor 1 can be moved up and down. On both sides of the conveyor, a large number of branch supply chutes 25 and 26 are arranged at intervals in the longitudinal direction of the conveyor and are provided in multiple stages in the vertical direction. Effects such as being able to branch-convey loads from the conveyor 1 to the branch supply chutes 25 and 26 at the positions can be obtained.
