And the test tube stand extruded plate is protruded from the slide groove, slides and pushes out the lowermost test tube stand, and descends while placing the remaining test tube stand on the upper part thereof, Thereafter, the robot is retreated backward in a state where it is drawn into the lower side of the mounting table, and then performs a rising motion.

[Operation] According to the above configuration, the extruded plate protrudes from the slide groove and slides to push out the lowermost test tube stand forward from the plurality of stacked test tube stands and to test the remaining test tube stand. It can be placed on the upper part of the extruded tube stand and lowered, and as a result, damage and noise due to the drop of the remaining test tube stand can be prevented. Further, a plurality of test tube stands can be simultaneously extruded with a simple configuration.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a preferred embodiment of a test tube stand supply apparatus according to the present invention.

In FIG. 1, a plurality of test tube stands 10 are stacked and stored in a stacker case 32 mounted on a mounting table 30.

The mounting table 30 is formed with a slide groove 30A along the test tube feeding direction shown in the direction A → B in the figure. Here, the slide groove 30A is for sliding an extrusion plate 34 described later. The length is formed from the lower portion of the stacker case 32 to a predetermined distance behind the stacker case 32. The predetermined distance is the stacker case 32
At the rear of the slide groove 30A to allow the extrusion plate 34 to protrude from the slide groove 30A. Further, the slide groove 30A is formed slightly forward of the stacker case 32 so that the test tube stand 10 can be pushed sufficiently forward from the stacker case 32.

 Next, a mechanism for driving the push plate 34 will be described.

In the figure, reference numeral 40 denotes an air cylinder for moving the pushing plate 34 back and forth, and the air cylinder 40 is provided with a base provided below the pushing plate 34 via a forward / backward moving shaft 42.
Transferred to 44.

An air cylinder 46 for vertically moving the extrusion plate 34 is disposed on the base 44, and the air cylinder 46 is fixed to the other end of the vertical movement shaft 48 by vertically moving the vertical movement shaft 48. The extruded plate 34 moves up and down.

Next, the operation of the device according to the present invention shown in FIG. 1 will be described with reference to FIG.

In FIG. 2, as shown in FIG.
34 is projected upward from the slide groove 30A, and is further slid forward.

As shown in (B), when the extruding plate 34 is slid forward, the lowermost test tube stand 10 is pushed forward. Here, the amount of protrusion of the extrusion plate 34 upward is set to be substantially the same as the height of the test tube stand.

As shown in (C), when the bottom test tube stand 10 is extruded forward, each test tube stand left above is placed on the test tube stand mounting surface 34B formed flat on the upper part of the extruded plate 34. Is placed. In this case, as described above, since the extruded plate 34 has a projection amount substantially equal to the height of the test tube stand,
The test tube stand above the step is placed on the extruded plate 34 smoothly without dropping abruptly downward. And
The extruded plate 34 descends as shown in (C), and as a result, the remaining test tube stand is stably mounted on the mounting table 30 as shown in (D). After that, the extruding plate 34 is
Of the slide groove 30A
And the above process is repeated.

As described above, according to the device according to the present invention, after extruding the bottom test stand, the remaining test stand is extruded.
Since the test tube stand can be transferred to the test tube stand mounting surface 34B formed on the upper part of the test tube stand, the test tube stand supply can be performed stably without damaging the test tube stand.

Next, the overall configuration of the embodiment of the test tube stand supply device according to the present invention will be described with reference to FIGS. 3 to 5.

In FIG. 3, in this apparatus, it is possible to integrally move up to ten extruding parts 52 provided with extruding plates 34,
It constitutes a continuous extrusion mechanism.

In FIG. 3, one of the extruding sections 52 out of 10
It is shown.

That is, the base 50 fixed via the front-rear movement shaft 42 from the air cylinder 40 for performing the back-and-forth movement includes ten extrusion units.
52 are aligned with their respective extrusion directions parallel.
Here, the base 50 is supported by slide guides 43-1 and 43-2 arranged in parallel via a longitudinal movement shaft 42 connected to the air cylinder 40. The pushing section 52 is provided with an air cylinder 46.
The extruding plate 34 arranged on the upper side can be moved up and down via 48.

Therefore, in the second embodiment, the air cylinder 40
Moves, the base 50 moves forward, which results in 10
The extruding section 52 of the table will simultaneously push the test tube stand forward.

Therefore, in the apparatus of the second embodiment, the pushing section 10
There is an advantage that only one air cylinder 40 is required to move back and forth with respect to the table.

Here, the speed controller 40a provided on the base 50 side of the air cylinder 40 adjusts the power of the air cylinder 40 to control the speed of its forward movement. In the present embodiment, the speed controller 40a is configured by an air valve having an electromagnetic valve.

FIG. 4 shows a specific structure of the extruding section 52 shown in FIG.

In FIG. 4, the extruded plate 34, which is the upper part of the extruded portion 52,
It has a frame 54 fixed to the air cylinder 46, and a cover 56 mounted on the frame 54 so as to be able to move slightly back and forth.

That is, in the case where the extruded plate 34 is brought into contact with the test tube stand, it is preferable to provide an impact absorbing means in order not to give an impact relating to the contact to the test tube stand. A spring 58 for elastically connecting the cover 54 and the cover 56 performs the operation.

The spring 58 has one end fixed to the cover 56 and the other end connected to the frame 54 through a long hole 56A formed in the cover 56.
Is fixed to a pin 60 that passes through a pin hole 54A formed in the hole.

That is, the cover 56 is always urged forward by the spring 58 with respect to the frame 54. As a result, when the cover 56 comes into contact with the test tube stand, the cover 56 is pushed back slightly backward. The shock is sufficiently absorbed.

In the figure, 62 is an overload detection switch,
It is fixed to the front part of the frame 54 via 64.

The operation of the overload detection switch 62 will be described with reference to FIG.

The overload detection switch 62 is connected to the head 6 via the arm 62a.
The head 62b is normally engaged with a notch 56B provided in the cover 56 by the upward urging action of the arm 62a.

However, as shown in FIG. 5, when the cover 56 is urged extremely rearward with respect to the frame 54 due to some obstacle, the head 62b comes off from the notch 56B, and at this time, the angle of the arm 62a , An overload is detected.

That is, even when the test tube stand is clogged halfway due to some kind of trouble, such a detection means can detect an overload, and can stop the test tube more quickly.

In this embodiment, the stacker case 32 shown in FIG. 1 is provided with a detector for detecting a position where the test tube stand is stored, and the stacker case 32 has no test tube stand. If the alarm has occurred, a predetermined alarm is output. Here, it is preferable to provide, for example, a light reflection type detector or a switch as shown in FIG. 5 as the detector for detecting the presence of the test tube stand.

As described above, according to the device of the present invention, it is possible to smoothly supply a test tube stand without damaging the test tube stand and without generating noise, and particularly in the stacker case 32. This has the effect that a large number of test tube stands can be stacked upward.

It is also possible to attach an elastic member to the test tube stand abutting surface of the extruded plate 34, or to attach an elastic member to the upper test tube stand mounting surface of the extruded plate 34 similarly. Can be relieved.

[Effects of the Invention] As described above, according to the test tube stand supply device according to the present invention, when the lowest test tube stand is extruded from a plurality of stacked test tube stands, the remaining test tube stand is extruded. It is possible to reliably prevent the test tube stand from being damaged and noise caused by the falling of the test tube stand, and it is possible to smoothly supply the test tube stand.

Therefore, from the above, in the stacker case, it is possible to increase the amount of the test tube stands to be stacked, and to reduce the number of times of artificial supply of the test tube stands to the stacker case.
