Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention has a structure in which a large number of freely rotating rollers are arranged in parallel and mounted on an arbitrary position on a roller conveyor for moving a load placed thereon, and a load moving on the conveyor is desired. Relates to a stopper that stops at the position.

[0002]

2. Description of the Related Art A roller conveyor is one in which a plurality of rollers are arranged in parallel and rotatably mounted on a frame, and a load placed on the rollers is moved by utilizing the free rotation of the rollers. Many of these roller conveyors are portable and used by transporting them to an arbitrary position, and there are also cases where two or more units are arranged in series to form a long moving system path, so there is no stopper at both ends. Is normal.

[0003]

As described above, since the conventional roller conveyor does not have a stopper, when a load placed on the roller conveyor is pushed and moved, there is a risk of inertial dropping from the end of the conveyor.

For this reason, conventionally, a metal piece or a wood piece is inserted between the rollers at the position where the load is desired to be stopped, and it is projected onto the conveyor, and this is used as a stopper. However, when a metal piece or a piece of wood is inserted as a stopper as described above, there is a risk that it may come off due to vibration during collision with luggage, or the luggage or rollers may be damaged.

An object of the present invention is to provide a stopper which can be easily mounted on a roller conveyor in order to solve the above problems and which is not likely to come off due to an impact.

[0006]

In order to solve the above-mentioned problems, the present invention provides an upward piece integrally with the front end of a main body which is placed on the front and rear rollers of a roller conveyor, and is attached to and detached from the front surface of the upward piece. The lower end of the freely fixed front plate is tilted backward so as to contact the front lower part of the front roller to form a diagonal piece, and the lower surface of the main body can be moved back and forth between the front and rear rollers to any position. That is, the downward piece that can be fixed at the position is provided.

[0007]

The present invention has the above-mentioned construction, and is convenient for storage and transportation because the main body, the front plate, and the downward facing piece are separated from each other and are not bulky.

Further, when mounting on the conveyor, the main body with the front plate fixed is placed on the conveyor, and the downward piece mounted on the main body so as to move back and forth is the roller on the rear side of the front plate and the roller behind it. Put in between.

After the stopper of the present invention is mounted on the roller conveyor as described above, when the load is placed on the front part of the conveyor and pushed toward the stopper, the load moves on the conveyor and stops at the stopper. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in the drawings, reference numeral 1 is a main body made of a steel plate or the like, the front portion of which is bent upward to form an upward piece 2. Reference numeral 3 is a front plate made of the same material as the main body 1, and bolts 4 inserted into the upward pieces 2 and a plurality of holes provided in the front plate 3
And the nut 5 to fix it by tightening it via a spring washer.

The lower end of the front plate 3 is inclined rearward to form an inclined piece 6. Reference numeral 9 denotes a downward piece made of the same material as that of the main body 1, and an upper portion thereof is bent backward to form a horizontal mounting portion 10, and the mounting portion 10 is provided with an elongated hole 11 in the front-rear direction.

Further, the main body 1 is provided with a rectangular opening 12 into which the downward piece 9 is inserted, and a bolt 13 into the elongated hole 11 is fixed on the main body 1 behind the main body 1 by means such as caulking.

In addition, slanting downwardly inclined edges 14 are formed on both sides of the mounting portion 10. The mounting portion 10 is placed on the main body 1, the bolt 13 is inserted into the elongated hole 11, the downward piece 9 is projected downward from the opening 12, and the wing nut 15 is screwed into and fixed to the bolt 13.

FIG. 1 shows a state in which the stopper of the above embodiment is mounted on the roller conveyor 16. Reference numeral 17 is a frame, and 19 is a plurality of rollers rotatably mounted on a plurality of bearings on both upper sides of the frame 17. The main body 1 to which the front plate 3 is fixed is placed on two rollers 19.

The lower piece 9 of the lower part of the main body 1 is adjusted in position so as to enter between the front and rear rollers 19 and the wing nut 1 is adjusted.
Fix with 5. In this state, when the load 20 is placed on the conveyor 16 and moved in the direction of the arrow, the load 20 contacts the front plate 3 protruding above the roller 19 and stops.

The stopper mounted on the conveyor 16 as described above becomes three parts of the main body 1, the front plate 3 and the downward piece 9 by removing the bolt 4 and the nut 5 and the wing nut 15. Further, the position of the downward piece 9 is adjusted for the rollers 19 having different pitches.

[0017]

[Effect] Since the present invention is constituted by the three parts of the main body, the front plate and the downward piece as described above, it is easy to assemble and disassemble, and also easy to install on the roller conveyor.

Further, when the front plate is attached to the conveyor, the lower part of the front plate and the diagonal piece contact from the front side to the front lower side of the front roller, and the rear downward piece is located at the rear side of the front roller. Even if the luggage hits the stopper, there is no risk of it slipping back and forth or coming off.
