Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a loading/unloading device comprising a pair of shirt conveyors.

[Conventional technology and its issues]

Conventionally, as one type of shirt torque conveyor, a device is known in which conveyor frames stacked in multiple stages move in and out of each other to expand and contract to form a predetermined length (see, for example, Japanese Utility Model Publication No. 54-41514). Also, a boxcar loading work device (for example, a boxcar loading device in which a belt conveyor is attached to a cart that runs on rails, and the belt conveyors are rotated or raised upwards and downwards)
44111) and as shown in Figure 8,
．． A portable telescoping belt conveyor is known in which a shirt conveyor consisting of second and third conveyor frames 2, 3, 4 is mounted on a truck l.

To explain this portable telescoping belt conveyor further, wheels 5, 5, etc. are attached to the trolley 1 so that it can be moved to any location, and the base of the first conveyor frame 2 is connected to the trolley. The first conveyor frame 2 is pivotally supported via a bracket 6 to be able to move up and down, and its tip is supported by a bendable support 7 relative to the truck 1, so that the first conveyor frame 2 can be moved up and down.

However, since such a portable telescoping belt conveyor is a low-profile cart 1, it is convenient to load and unload cargo onto the base end of the shirt belt conveyor, but it is difficult to find a place to place the baggage and to unload the baggage. If the location changes, the direction of the cart must be changed each time, and this change is particularly difficult because the cart is not self-propelled.

Therefore, it is conceivable to apply a normal trunk to this trolley, but the truck bed will be higher than the ground, making it inconvenient to load and unload from the base end of the shirttle conveyor, so such an idea remains unchanged. Cannot be hired.

[Means to solve the problem]

Therefore, the present invention was created in order to eliminate the disadvantages of these conventional examples, and its gist is to provide a rotating frame that is rotatably installed on a truck, and a rotating frame that is provided at the upper end of the rotating frame. A loading/unloading device comprising a substantially horizontal intermediate belt conveyor, and a pair of shirt conveyors facing oppositely to each other across the intermediate belt conveyor and pivotally connected to the revolving frame so as to be able to move up and down. It's in the device.

This shirt conveyor is suitable for use as a truck loader (a truck loading machine) or a shirt conveyor for loading into a warehouse.

Now, in these figures, 10 is a truck, 11 is a chassis frame for its loading platform, and 12 is an outrigger that can extend from the chassis frame 11 to the left and right. A frame 14 is mounted, and this rotating frame 14 is equipped with a rotating device 14.
It is possible to turn by a.

A first shirt torque conveyor 15 and a second shirt torque conveyor 16 are mounted on the upper end of the revolving frame 14 in opposite directions and are movable up and down. This first
The shirt conveyor 15 is the first one. second and third conveyor frames 23a;

23b and 24c are configured to be able to freely slide on each other, and the tip of the first conveyor frame 23a is supported by an undulation cylinder 17 pivotally connected to the revolving frame 14. Therefore, the first shirt conveyor 15
performs an upward and downward movement by the expansion and contraction of this undulating cylinder 17. Further, the second shirt conveyor 16 is connected to the first shirt conveyor 16. Second.
and third conveyor frames 24a, 24b, 24c
The first conveyor frame 24a is configured such that it can freely slide on each other, and the tip of the first conveyor frame 24a is supported by another undulating cylinder 18 that is pivotally connected to the swing frame 14.

In addition, 1. A movable nose plate 19 is attached to the tip of the second shirt torque conveyor 15, 16, respectively.

A horizontal intermediate belt conveyor 20 is provided between the first and second shirt conveyors 15 and 16. That is, in FIGS. 4 and 5, intermediate belt conveyor boots υ-21 and 22 are attached to the upper surface of the revolving frame 14, and these pulleys 21
．． A conveyor belt 30 is suspended around 22. Also,
First conveyor frames 23a and 24a are pivoted around the axis of intermediate belt conveyor pulleys 21 and 22, shirt conveyor pulleys 25 and 26 are attached to these first conveyor frames 23a and 24a, and these An ISl and a second conveyor belt 31, 32 are suspended around pulleys 25, 26, respectively. therefore,
The first conveyor frames 23a, 24a move up and down with the intermediate belt conveyor pulleys 21.22 as pivot points due to the expansion and contraction of the above-mentioned undulation cylinders 17.18.

Also, these first conveyor frames 23a.

As shown in FIGS. 6 and 7, brackets 27, 27, etc. are fixed to the outside of the revolving frame 14, and the brackets 24a are arranged at the axis positions of the shuttle conveyor pulleys 25, 26 in these brackets 27. One conveyor frame 23a, 24a may be pivotally connected.
