Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeding device for rod-shaped or plate-shaped objects, and particularly to a feeding device useful for feeding / moving a magazine, for example, radiation exposure. It is a supply device for measuring TL badges for dose measurement with an automatic machine and supplying magazines containing TL badges one by one to an automatic measuring device.

2. Description of the Related Art A conventional feeding device is a belt system shown in FIG.
There are many methods such as the chain method shown in FIG. 9 (b) and the claw method shown in FIG. 9 (c).

Problems to be Solved by the Invention In the conventional method, the simple method (belt, chain method) or the claw method with high movement position accuracy may be used for moving the magazine, but in the automatic device, Since the magazines are also collected, it is also necessary that the magazines after being supplied are supplied on a flat surface so that they can be moved in the other direction easily, and that the supplied magazines and the collected magazines do not interfere with each other. We needed a new device that was simple and reliable.

Means for Solving the Problems In order to solve the above problems, a supply device of the present invention is a fixed stair-shaped fixed base, and is provided in parallel to the fixed base and is slid on the front and rear of the stairs in a planar manner. A stairs-shaped movable table that moves, each stair part of the movable table is provided at least corresponding to each stair part of the fixed table, and the front and rear of each stair part of the fixed table and the movable table. The arrangement of directions is the same direction, the height of each stair part of the movable table is lower than the height of the stair part of the fixed table to which each stair part of the movable table corresponds before the movement, and the movable table after the movement. Is higher than the height of the corresponding stairs of the fixed base.

In addition, a magazine that moves on the fixed base and the movable base is provided, and when the magazine is located over the stairway part before the movement and the stairway part after the movement during the movement of the magazine, The rising part rising from the stair part to the stair part one step higher and the magazine come into contact with each other,
A recess is provided on the bottom surface of the magazine so that the rising portion pushes the magazine.

Further, a recess is formed on the bottom surface of the magazine by using at least one of a spring, a pin and a hinge mechanism.

Further, the center of gravity of the magazine is provided on the rising portion side.

Action In the above configuration, when the supply target is placed on the fixed base and the movable base is moved, the movable base pushes the supply target and pushes out the supply target. Next, when the movable table is returned to its original position, the supply target is caught on the stairs of the fixed base and the supply target does not return.

Further, when the magazine is supplied, since the concave portion is provided on the bottom surface of the magazine and the center of gravity of the magazine is provided on the rising portion side which rises from the step portion before moving to the step portion one step higher, When the magazine is located across the stairs part before the movement and the stairs part after the movement, the rising part rising from the stairs part before the movement to the stairs part one step higher and the magazine come into contact with each other,
The rising portion pushes the magazine, so that it is possible to prevent the stairway portion of the movable table from sneaking under the magazine and hindering the supply and movement of the magazine.

Example One example of the present invention will be described below.

FIG. 1 shows a magazine 1 and 2 is a component insertion portion.
As shown in FIG. 2, the magazine 1 has a recess 3 formed on the bottom surface. Reference numeral 4 is a rack tooth forming part.

FIG. 3 shows a magazine supply device, 5 is an upper base plate, 7 is a step-like fixing base fixed to the upper base plate 5,
Reference numeral 6 is a stair-shaped movable base movably provided on the upper base plate 5, 8 is a sending and collecting gear, and 9 is a collection completion detecting plate.

In the above structure, the magazine 1 is arranged on the fixed base 7 and the movable base 6 to be in the state shown in FIGS. 4 and 5.
Next, when the motor in the apparatus is rotated, the movable table 6 moves and the magazine 1 is supplied to the lower stage. The supplied magazine 1 is sent to the automatic measuring device by the sending-out and collecting gear 8 and is collected after the measurement is completed. The recovered magazine 1 is pushed by the magazine 1 to be supplied next and moves toward the recovery completion detecting plate 9. By repeating the above operation, all magazines 1 can be supplied.

The above-mentioned supply process of the magazine 1 is illustrated in FIG.

That is, FIG. 6 (a) shows the state of the supply start,
FIG. 6 (b) shows the supply movement state, FIG. 6 (c) shows the movement completion state, and FIG. 6 (d) shows the state where the movable table 6 is returned. The movable table is slid in the direction of the arrow shown in FIG. 6 (the front-back direction of the stairs).

FIG. 7 is an enlarged view of FIG. 6 (b). Due to the recess 3 formed on the bottom surface of the magazine 1,
When the magazine 1 is pushed by the movable table 6, the inclination becomes small. Therefore, the rear lower portion of the magazine 1 is reliably pushed by the movable table 6, and the magazine 1 is reliably fed.

8 (a), (b), (c), (d),
(E) shows examples in which the same effects as those obtained when the concave portion 3 is formed on the bottom surface of the magazine 1 are obtained.
FIG. 8A shows a claw 11 biased downward by a spring 12, FIG. 8B shows a leaf spring 13 provided on the lower surface, and FIG. 8C shows a pin 14 downward by a spring 15. FIG. 8 (d) shows a case in which the magazine 1 is divided at the central portion and is connected by the hinge mechanism 16, and FIG. 8 (e) shows a case in which the center of gravity of the magazine 1 is provided at the rear.

Although the present embodiment has been described using the magazine supply device, the present invention is not limited to the magazine supply, and it goes without saying that the present invention can be used for supplying other objects.

EFFECTS OF THE INVENTION As is apparent from the above description, according to the present invention, when the supply target is placed on the fixed base and the movable base is moved, the movable base pushes the supply target, pushes out the supply target, and moves. When the table is returned to its original position, the supply target is caught on the stairs of the fixed base and the supply target does not return.

Further, when the magazine is supplied, since the concave portion is provided on the bottom surface of the magazine and the center of gravity of the magazine is provided on the rising portion side which rises from the step portion before moving to the step portion one step higher, When the magazine is located across the stairs part before the movement and the stairs part after the movement, the rising part rising from the stairs part before the movement to the stairs part one step higher and the magazine come into contact with each other,
Since the rising portion pushes the magazine, it is possible to prevent the stairway portion of the movable table from sneaking under the magazine and hindering the supply / movement of the magazine.

As described above, according to the present invention, the supply target can be moved only by sliding the movable table in the plane direction, and it is not necessary to move the movable table itself in the vertical direction. An operating supply device can be provided.
