Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention is used in the field of transporting powder and granular materials, cardboard boxes, and the like.

(b) Conventional technology Conventional conveyor devices have an endless chain that spans the front and rear sprockets, a plurality of supports each having a rectangular cross section are attached to this chain in parallel, and gaps are provided between each support. This allows for smooth arc movement at the front and rear ends.

(c) Problems to be solved by the invention However, with the above structure, it is possible to transfer cardboard boxes, bags, etc., but when transferring powder or granules, etc., it is possible to transfer between the supports. Because of this, a separate conveyor device had to be used, resulting in very poor work efficiency.

(d) Means for Solving the Problems The present invention provides a pair of left and right endless chains extending between a pair of front and rear sprockets, and a support member and a shielding member are provided between the pair of chains for each pitch of the chain. A holding part opening upward is provided on the front and rear surfaces of the support body, and the connecting parts of the front and rear ends of the shielding member are fitted into this holding part, and the front and rear ends of the shielding member are attached to the chain. This invention relates to a conveyor device that is located at the axis of each pin.

(e) Embodiment An embodiment will be explained below with reference to the drawings. Fig. 1 shows a state in which the conveyor device of the present invention is attached to a freight car. 1 is a box-shaped body provided on the car body 2; A door 3 is provided at the rear of the body 1, and a canopy 4 is provided above.

Reference numeral 5 denotes a conveyor device provided at the bottom of the body 1, and this conveyor device will be explained below.

6, 6 are sprockets provided at the front and rear, and the front sprocket 6 is connected to a driving motor 7.

Endless chains 8, 8 are stretched between the pair of sprockets 6, 6, and these chains 8, 8
A conveyor main body 9 is attached between them, and the conveyor main body 9 can be moved back and forth by driving the chains 8, 8.

The conveyor main body 9 includes a plurality of supporting bodies 10 and a plurality of shielding members 1 for shielding gaps between the supporting bodies 10.
1..., supporting body 10... and shielding member 1
1... are attached alternately to each pitch of the chains 8, 8.

As shown in FIG. 4, the supports 10 have a rectangular cross section and extend in the left-right direction, and L-shaped mounting portions 12 extending downward from part of the chains 8, 8 are fixed to the lower portions of both ends. The flat upper surface 13 supports the cargo.

Furthermore, holding portions 14 that open upward are provided on the front and rear surfaces of the supports 10, respectively.

The shielding members 11 are made of a somewhat flexible material and extend in the left-right direction to have approximately the same length as the supports 10.

The cross section has a shape as shown in FIG. 4, with a flat portion 15 at the center and connecting portions 16, 16 at the front and rear ends that can be fitted into the holding portions 14, 14.

Further, the connecting parts 16, 16 are connected to the holding parts 14, 1
4, the front and rear ends of the flat portion 15 are located on the extension line of the axis 0 of each pin 17 of the chains 8, 8, and the conveyor body 9 is positioned at the sprockets 6, 6. The distance () between the front and rear ends of the flat portion 15 does not change even if the flat portion 15 is shaped like an arc.

In other words, only the connecting portion between the flat portion 15 and the connecting portion 16 of the shielding member 11 is bent, and no tensile or compressive force is applied to the flat portion 15 and the connecting portion 16. . 18 is a guide plate provided on the inner wall of the body 1.

19 is a cradle for the conveyor body 9.

The present invention has the above-mentioned structure, and its operation will be explained next. First, when transporting a cardboard box or the like, the door 3 of the body 1 is opened, the cargo is placed on the conveyor main body 9, and the motor 7 is used to convey the cargo. By moving the main body 9 forward, the cargo is moved forward, and at the same time, the cargo is sequentially placed on the conveyor main body 9, and finally the door 3 is closed and the cargo is transported to the destination.

When the destination is reached, the baggage can be unloaded one by one by opening the door 3 and moving the conveyor main body 9 backward.

At this time, since the upper surface 13 of the support body 10 is flat, the load can be stably supported.

Next, when transporting powder or granules, etc., open the canopy 4, load the powder onto the conveyor body 9, and when the inside of the body 1 is full, close the canopy 4 and transport it to the destination. .

Upon arrival at the destination, the powder and granules can be unloaded one by one by opening the door 3 and moving the conveyor main body 9 backward.

At this time, since the shielding member 11 is provided between the supports 10 of the conveyor main body 9, there is no fear that powder or granules will spill from between the supports 10. Even when moving, the front and rear ends of the flat parts 15 of the shielding members 11 are located on the extension line of the axis 0 of each pin 17 of the chains 8, 8, so the distance between the front and rear ends of the flat parts 15 ( ) is always constant, and only the bending is applied to the connecting portion between the flat portions 15 and the connecting portions 16, and no tensile or compressive force acts on the flat portions 15 and the connecting portions 16, and the connecting portion 16... are fitted into the holding portion 14, but this fitting will not come off.

(g) Effects of the Invention As described above, the present invention alternately attaches supports and shielding members to each pitch of the chain, positions the front and rear ends of the flat portions of the shielding members at the axis of each pin of the chain, Since the connecting part of the shielding member and the holding part of the support body are fitted together, it is possible to transport powder and granular materials as well as transporting cardboard boxes, etc., which increases work efficiency. Even during movement, no tensile or compressive force is applied to the flat portion or the joint portion of the shielding member, and the fitting between the joint portion and the holding portion will not come off.
