Description

[Detailed Description of the Invention] (a) Technical Field of the Invention This invention provides a method for stacking a plurality of cases containing parts, etc., in order to measure the characteristics of the parts, etc.
This invention relates to an individual case sending method that ensures that each case is sent to a case receiver when cases are sent out one by one.

(b) Prior art and problems The configuration of the prior art will be explained with reference to FIGS. 1 and 4.

First, the configuration of each part will be explained.

1A to 1D are cases, 2A and 2B are stoppers,
3A and 3B are stopper drive mechanisms, 4A and 4B are guides, 5A and 5B are case holders, 6 is a moving table, 7
A and 7B are stoppers, 8A and 8B are stopper drive mechanisms, and 9A and 9B are shafts.

In the case 1A, components such as semiconductors are housed in a fixed orientation.

The guide 4A and the guide 4B are held at a distance that allows the case 1A to be accommodated, and the case 1A is accommodated in the guide 4A and the guide 4B.

Case 1 placed inside guide 4A and guide 4B
A plurality of other cases 1B to 1D are stacked on top of A.

That is, a plurality of cases 1B to 1D are housed in the guides 4A and 4B in the same direction, with the case 1A at the lowest position.

Figure 1 shows cases 1A to 1D being guided by guides 4A and 4.
This figure shows the state maintained during period B.

The lowest case 1A is as shown in Figure 1.
Case 1B, which is one level above case 1A, is supported by stopper 2A and stopper 2B, and case 1B is supported by stopper 7 in FIG.
It is held by A and 7B.

The stopper drive mechanism 3A is composed of, for example, a cylinder, and drives the stopper 2A shown in FIG. 1 with a piston or the like. Stopper 2B and stopper drive mechanism 3
Do the same for relationship B.

Further, the relationship between the stoppers 7A, 7B and the stopper drive mechanisms 8A, 8B can be configured in a similar manner.

When the stopper drive mechanisms 3A and 3B shown in Fig. 1 are driven to release the stoppers 2A and 2B shown in Fig. 1, the case 1A is moved by gravity to the case receiver 5A,
Fall into 5B.

Case 1A dropped into case receivers 5A and 5B
The shaft 9 is driven by a drive mechanism (not shown).
Using A and 9B as guides, the entire moving table 6 is moved.

Next, by driving the stopper drive mechanisms 3A and 3B to operate the stoppers 2A and 2B again, and releasing the stoppers 7A and 7B shown in FIG. 4, the case 1B shown in FIG. 1 will be supported at the lowest position. become.

By repeating this operation, the lowest cases can be dropped onto the case receivers 5A and 5B one after another, and by controlling the moving table 6, the cases can be sent out individually. .

However, such an individual feeding mechanism has the following problems.

When the stopper drive mechanisms 3A and 3B are simultaneously driven to drop the case 1A, one end of the case 1A hits the edge of the case receiver 5A or the case 5B.
The orientation of the case 1A may change during the fall.

If the orientation of the case 1A is involved, the orientation of the case 1A must be confirmed in order to take out the parts etc. housed in the case 1A, which increases the number of work steps.

(c) Purpose of the invention This invention has a mechanism as shown in FIGS. 1 and 4,
The purpose is to prevent the orientation of the case from changing when the case is dropped onto the case receiver 6 by releasing the stoppers 2A, 2B.

(d) Embodiments of the Invention A method for individually feeding cases according to the present invention will be explained with reference to FIGS. 1 to 3.

FIG. 1 shows a state in which the stoppers 2A and 2B support the lower end of the case 1A.

FIG. 2 shows a state in which only the stopper 2A is released in the direction of the arrow and one end of the case 1A is dropped into the case receiver 5A.

Figure 3 shows the stopper 2 with one end of the case 1A inserted into the case receiver 5A as shown in Figure 2.
This shows the state in which B is released in the direction of the arrow.

In the state shown in FIG. 2, the other end of the case 1A is supported by the stopper 2B, so even if the edge of the case 1A hits the case receiver 5A, the direction will not change.

That is, this invention does not release the stoppers 2A and 2B simultaneously, but releases the stoppers 2A and 2B individually, so that when the case 1A or the like is dropped onto the cases 5A or 5B, the direction of the case 1A or the like changes. I tried to avoid it.

(e) Effects of the Invention According to this invention, the stopper 2A is released and the stopper 2B is released after one end of the case 1A etc. enters the case receiver 5A.
Even if the case 1A and the like are dropped onto the case receivers 5A and 5B, the orientation of the case 1A and the like can be prevented from changing.
