Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is used in the field of transferring powdery or granular materials, cardboard boxes and the like.

(b) Prior art A conventional conveyor device, in particular, a support body of a conveyor main body and a chain are connected to each other as shown in FIG.
A large-diameter upper hole (02) and a small-diameter lower hole (03) are provided in (01), and a bolt (04) through which both the holes (02) and (03) are inserted is attached to a chain (0
5) The support body (01) is screwed into the L-shaped mounting portion (06).
To the chain (05), and to prevent the part of the load on the support from being caught in the upper hole (02) and the powder particles from entering the upper hole (02). 07) is fitted.

However, in the above structure, it is necessary to attach two kinds of members, a bolt and a rubber lid, in order to connect the support to the chain, which increases the number of manufacturing steps and the storage of the members is very troublesome.

(c) Problems to be Solved by the Invention The present invention is to solve the problems as described above, and a connecting bolt for connecting a support to a chain is formed with a large-diameter head portion and a small-diameter screw portion. When the threaded portion is screwed into the chain side, the head portion closes the upper hole.

(d) Means for Solving the Problems In the present invention, a pair of left and right endless chains are provided between a pair of front and rear sprockets, and an L-shaped mounting portion having a screw hole inside each chain. And a support body having a rectangular cross section for supporting luggage on the upper surface of the pair of left and right mounting portions, and a large diameter at both ends of the support body at positions facing the screw holes of the mounting portion. Upper hole and a small-diameter lower hole are provided, and the support body is provided with an engaging bolt composed of a head portion and a screw portion, and the head portion closes the upper hole and the lower surface thereof abuts the lower surface of the support body. The present invention relates to a conveyor device in which the upper surface is made to coincide with the upper surface of the support body, and the screw portion penetrates the lower hole and is screwed into the screw hole.

(e) Example An example will be described 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 vehicle.
Is a box-shaped body provided on the vehicle body (2), a door (3) is provided behind the body (1), and a canopy (4) is provided above it.

(5) is a conveyor device provided below the body (1), and this conveyor device will be described below. (6) and (6) are front and rear sprockets, and a drive motor (7) is connected to the front sprockets (6).

A pair of left and right endless chains (8) and (8) are stretched around the pair of sprockets (6) and (6).
The conveyor body (9) is attached to (8) and (8), and the chain
The conveyor body (9) can be moved back and forth by driving (8) and (8).

The conveyor body (9) comprises a plurality of supports (10).
It is composed of a plurality of shielding members (11) for shielding the gap between the (10). As shown in FIG. 2, the support (10) has a rectangular cross section and extends in the left-right direction.
The L-shaped attachment part (12) extending downward from a part of the chains (8) and (8) is fixed, and the flat upper surface (13) supports the luggage. There is. Further, the support (10) ...
The holding portions (14) open to the upper and lower sides are respectively provided on the front and rear surfaces.

The shielding member (11) extends in the left-right direction so as to have substantially the same length as the support body (10), and its cross section is as shown in FIG. It has a mold and has a flexible part (15) which is flexible at the center and slightly bent, and front and rear ends are hard parts (16) which can be fitted to the holding parts (14), (14). ) And (16). Further, the position of the shielding member (11) when the hard parts (16), (16) are fitted to the holding parts (14), (14) matches the pitch diameter of the sprockets (6), (6). Therefore, the flexible portion (15) at the center of the shielding member (11) can be flexed with little variation.

FIGS. 2 to 4 show the connecting structure of the support (10) and the chain (8).
7) and a lower hole (18) having a small diameter are formed, and a screw hole (19) of the mounting portion (12) is made to face below the lower hole (18).

A connecting bolt (2) connecting the support (10) and the chain (8)
0) is composed of a head portion (21) having substantially the same diameter as the upper hole (17) and a screw portion (22) having a diameter slightly smaller than that of the lower hole (18). (10) By bringing the lower surface into contact with the lower surface, the upper surface of the supporting member is aligned with the upper surface of the support body (10), and the screw portion (22) is attached to the lower hole (1).
8) is penetrated and screwed into the screw hole (19) of the mounting portion (12), and in this state, the head portion (21) closes the upper hole (17).

In addition, a hexagonal hole (23) is provided in the center of the upper surface of the head (21), and a connecting bolt is inserted by inserting a hexagonal wrench into the hexagonal hole (23).
(20) can be rotated.

Reference numeral (24) is a guide plate provided on the inner wall of the body (1).

(25) is a cradle for the conveyor body (9). The present invention is configured as described above, and the operation will be described next.First, when transporting a cardboard box or the like, the door (3) of the body (1) is opened and the load is placed on the conveyor main body (9). By moving the conveyor body (9) forward by the motor (7), the load is moved forward, and at the same time, the load is transferred to the conveyor body.
Place them on (9) in sequence, finally close the door (3) and transport to the destination. When the vehicle arrives at the destination, the doors (3) are opened and the conveyor body (9) is moved backward, so that the loads can be sequentially unloaded.

At this time, since the upper surfaces (13) of the supports (10) ... are flat, the luggage can be supported in a stable state.

Next, when transporting powdered particles, etc., open the canopy (4),
The granular material is loaded on the conveyor body (9), and when the body (1) is full, the canopy (4) is closed and the powder is transported to the destination.

When the vehicle arrives at the destination, the door (3) is opened and the conveyor body (9) is moved backward, so that the granular material or the like can be sequentially unloaded.

At that time, a shield member (11) is provided between the support bodies (10) of the conveyor body (9), and the upper hole (17) is the head of the coupling bolt (20). Since it is closed at 21), there is no risk of powder particles spilling, and even when the conveyor body (9) moves in an arc at the front and rear ends, the shielding member (11)
Since the flexible part (15) is formed in ......, it can move smoothly in an arc.

When replacing the support (10) due to deformation, etc., rotate the connecting bolt (20) from above and rotate the connecting bolt (2).
The old support (10) with the 0) …… removed from the mounting section (12) ……
Is replaced with a new support (10).
By rotating the lower surface of the head (21) of the support (20) until it comes into contact with the lower surface of the support (10), the support (10) can be replaced.

(f) Effects of the Invention As described above, according to the present invention, when the connecting bolt for connecting the support body to the chain is formed by the head portion and the screw portion, and the support body is connected to the chain side by the screw portion, the head portion is It is only necessary to rotate the lower surface until it comes into contact with the lower surface of the support, and the head part closes the upper hole of the support when it is joined, so that the work of attaching the support to the chain becomes very easy and There is no possibility of catching luggage or spilling of powder or granules due to opening of the upper hole, and the storage of the members becomes easy.
