Abstract

PURPOSE:To simplify the configuration of a TL badge magazine supplying mechanism for measurement of radiation exposure and provide certain operations by forming a recess at the bottom of the magazine, combining a stepped stationary table with a moving table, and by moving the magazine. CONSTITUTION:A magazine 1 is arranged on a fixed stage 6 and a moving stage 7, which is moved ahead by a motor, not illustrated. The advance of this moving stage 7 transfers the magazine 1 to the fixed stage 6 situated one stage lower one by one. When the feed is finished, the magazine 1 is sent out to an automatic measuring gauge by a delivery collection gear 8. When measurement is finished, the magazine 1 is collected, and pushed by the next magazine 1 and moves to a collection finish sensing plate 9. This cycle of operations is performed repeatedly. This accomplishes simple construction and sure supply.

Description

Detailed Description of the Invention To Industrial Application Field 2-7 The present invention is directed to an automatic measuring device that measures magazines containing TL badges one by one in order to measure, for example, TL badges for measuring radiation exposure dose using an automatic machine. It is a mechanism for supplying

In addition, it can be widely used as a feeding mechanism for rod-shaped and plate-shaped objects.

Conventional technology The conventional feeding mechanism is a belt type shown in FIG. 9(a).

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 system, when it comes to simply moving the magazine,
It was considered to use a simple method (belt or chain method) or a claw method with good movement position accuracy, but automatic devices do not have to collect the magazine, and the magazine is moved in the other direction after being supplied. In order to make it easier, it was necessary that the magazines be fed on a flat surface so that the fed magazines and the collected magazines would not interfere with each other, and a new mechanism that was simple and operated reliably was needed.

3 H/ Means for Solving the Problems In order to solve the above problems, the magazine supply mechanism of the present invention includes a pair of stair-shaped fixing bases to which a bar-shaped or plate-shaped magazine is fixed, and a movable staircase. The magazine is equipped with a mechanism for moving the magazine by the combined operation of movable bases, and has four parts formed on the bottom surface of the magazine.

Operation In the above configuration, when the magazine is placed on the fixed base and the movable base is moved, the movable base pushes the lower corner of the magazine and pushes out the magazine. When the movable base is returned to its original position, the magazine gets caught on the stairs of the fixed base, and the magazine does not return.

Example Examples of the present invention will be described below.

FIG. 1 shows a magazine 1, and 2 is a component insertion section. As shown in FIG. 2, the magazine 1 has a recess 3 formed in its bottom surface. 4 is a rack tooth type acid part.

FIG. 3 shows a device using a magazine supply mechanism, in which 5 is an upper base plate, 6 is a stair-shaped fixed stage fixed to the upper base plate 6, and 7 is a stair-shaped fixed stage movably provided on the upper base plate 6. In the movable stage, 8 is a sending and collecting gear, and 9 is a collection completion detection plate.

In the above configuration, the magazine 1 is arranged on the fixed stage 6 and the movable stage 7, and is in the state shown in FIGS. 4 and 5. Next, when the motor in the device is rotated, the movable stage 7 moves,
Supply magazine 1 to the lower stage. The magazine 1 that has been completely supplied is sent out to the automatic measuring device by the sending and collecting gear 8, and is recovered after the measurement is completed. Recovered magazine 1
For example, it is pushed by the next magazine 1 to be supplied and moves in the direction of the collection completion detection plate 9. By repeating the above operations, all magazines 1 can be fed.

The above-described feeding process of the magazine 1 is illustrated in FIG. 6.

That is, FIG. 6(a) shows the supply start state, FIG. 6(b) shows the supply movement state, and FIG. 6(C) shows the movement completion state.
FIG. 6(d) shows the state in which the movable stage 7 is returned.

5B-7 FIG. 7 is an enlarged view of FIG. In this state, the inclination is small, and the rear lower part of the magazine 1 is reliably pushed by the movable stage 7, so that the magazine 1 is reliably fed.

In addition, Fig. 8 (a), (b), (C), (
d) and (Q) respectively show examples in which the same effect as when the recess 3 is formed on the bottom of the magazine 1 is obtained, and Fig. 8 (a) shows an example in which the claw 11 is attached downward by the spring 12. FIG. 8(b) shows the one with the plate spring 13 on the bottom surface, FIG. 8(C) shows the pin 14 with the spring 15 pushing it downward, and FIG. 8(d) shows the magazine 1. The magazine 1 is divided at the center and connected by a hinge mechanism 16, and the center of gravity of the magazine 1 (see Fig. 8) is located at the rear.

Effects of the Invention As is clear from the above description, according to the present invention, by providing the recessed portion in the bottom surface of the magazine, the magazine can be reliably fed by the movable stage.
