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.

However, with the above structure, it is possible to transport cardboard boxes, paper, etc., but when transporting powder and granules, etc., a separate conveyor device is required because the spillage spills from the gaps between the supports. There was a problem that the work efficiency was very low.

(c) Problems to be solved by the invention The present invention solves the above-mentioned problems.
A shielding member having an elastic part that can be expanded and contracted at least in the center is provided in the gap between each support.

(d) Means for Solving the Problems The present invention provides a chain that spans between a pair of front and rear sprockets, a plurality of supports that extend in the left and right direction are attached to the chain at appropriate intervals, and has a flat upper surface, and flat mounting parts are provided above the front and rear surfaces thereof, and a flat shielding member having an elastic part that can be expanded and contracted at least in the center is bolted between the mounting parts. This invention relates to a conveyor device in which the upper surface of the shielding member is lower than the upper surface of the support, and the bolts are vertically attached from above.

(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 below 1, and this conveyor device will be explained below.

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

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 to the chain 8,
8, the conveyor body 9 can be moved back and forth.

The conveyor main body 9 is composed of a plurality of supports 10 and a plurality of shielding members 11 for shielding gaps between the supports 10.

As shown in FIG. 3, the supports 10 have a rectangular cross-section and extend in the left-right direction, and are provided with L-shaped mounting portions 12 at the lower portions of both ends that extend downward from a portion of the chains 8, 8. is fixed so that the flat upper surface 13 supports the cargo. Further, above the front and rear surfaces of the support body 10, a flat mounting portion 1 is provided.
4 and 14 are provided, respectively.

The shielding member 11 extends in the left-right direction to have approximately the same length as the support 10, and has a flat plate-like cross section as shown in FIG. The front and rear ends have hard parts 16, 16, and the hard parts 16, 16 are connected to supports 10, 10.
Bolts 17 are fixed to the mounting parts 14, 14 of
The upper surface of the shielding member 11 is positioned slightly below the upper surface 13 of the support body 10, and bolts 17 are attached vertically from above.

Furthermore, the position of the shielding member 11 when the hard parts 16, 16 are attached to the mounting parts 14, 14 is made to match the pitch diameter 18 of the sprockets 6, 6, so that fluctuations in expansion and contraction of the elastic part 15 can be reduced. .

19 is a guide plate provided on the inner wall of the body 1. 20 is a cradle for the conveyor main body 9.

In addition, in the embodiment, an elastic part is provided in the center as a shielding member.
Although it has a structure with hard parts at both ends, the same effect can be obtained even if the whole is made of an elastic member and both ends are bolted to the support side via a press plate. .

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 arriving at the destination, 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 surfaces 13 of the supports 10 are flat, the cargo can be stably supported.

Further, the upper surface of the shielding member 11... is connected to the support body 10...
Since it is lower than the upper surface 13, the shielding member 1
1... will not directly hit the cargo, and the shielding member 11... will not be damaged.

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 a shielding member 11 is provided between the supports 10 of the conveyor body 9, there is no fear that powder or granules will spill from between the supports 10, and the conveyor body at the front and rear ends Even when 9 moves in an arc, the elastic part 15 expands and contracts, so it can move smoothly in an arc.

(f) Effects of the Invention As described above, the present invention provides a shielding member having an elastic portion at least in the center between a plurality of supports attached to a chain, so that powder and granular materials are prevented from being collected while transporting cardboard boxes and the like. It also becomes possible to transport it, increasing work efficiency.

Further, since the shielding member has an elastic portion, each support can be smoothly moved in an arc.

Furthermore, when transporting cargo, since the upper surface of the shielding member is lower than the upper surface of the support, the shielding member does not directly hit the cargo and the shielding member is not damaged.

Further, the flat shielding member is bolted to the flat mounting portion, and since the bolts are vertically mounted from above, the shielding member can be easily mounted. Furthermore, since the upper surface of the support body is flat, it is possible to support the load in a stable state.
