JPH05264540A - Drum container for automatic urine analyzer - Google Patents

Abstract

PURPOSE:To carry a test paper into a gap in a pawl within a drum by eliminating warping thereof. CONSTITUTION:A round or angular bar 11 as long as a test paper 8 is put into a drum 1 and the drum is turned so as to carry the test paper to a pawl part 9 within the drum by a rotating force or the like of the round bar turning the round bar together with the test paper in the drum. The round or angular bar is made of metal such as brass. The bar presses on the test paper by own gravity to get the test paper warped variously straightened thereby allowing the carrying thereof smoothly into the gap of the pawl part within the drum.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a test strip taking-out mechanism, a drum container internal structure and a test strip taking-out method in an automatic urine analyzer.

[0002]

2. Description of the Related Art In a conventional apparatus, since only the test paper is stored in the drum, the action of pushing the test paper into the inner claw of the drum is performed by the rotational force of the drum and the weight of the other test paper.

[0003]

The above-mentioned prior art does not smoothly take out any test paper, and there is a problem that the test paper take-out rate decreases as the warpage increases from 2 mm to 3 mm. there were.

An object of the present invention is to eliminate the warp of the test paper and carry it into the gap of the claw inside the drum.

[0005]

In order to achieve the above object, a round bar or a square bar having the same length as the test paper is put in the drum, and the drum is rotated to form the round bar together with the test paper in the drum. While rolling, the test paper is carried to the claw inside the drum by its rotational force. Also, by making round bars and square bars with metal such as brass, their own weight becomes a weight and overlaps with the test paper, and the test paper with various sleds is stretched straight and smoothly in the gap between the claws in the drum. It is intended to be carried to. Further, the round bar having the same length as the test paper also has an action of arranging the test papers in various directions in the drum in a relatively parallel manner.

[0006]

[Function] Dimensions (outer diameter) of round bars, square bars, etc. that can be inserted in the drum
Since it is larger than the gap size of the claw in the drum, the round bar does not enter the gap of the claw instead of the test paper and the test paper does not come out. Further, since the length of the round bar or the like is not shorter than the inner diameter of the drum, the round bar does not stand or lie down while the drum is rotating, so that the test paper take-out operation does not malfunction.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. Test Paper Retrieval Mechanism FIG. 1 is composed of a drum container (1) for storing the test paper, a drum base (2) for fixing and rotating the drum container, and a sorter rack mechanism (3) for feeding the test paper one by one. The drum container and the sorter rack mechanism are connected to the drive motors (6) and (7) by timing belts (4) and (5). While rotating the drum container, the test papers (8) are hooked one by one on the drum inner pawls (9) and dropped onto the sorter rack. The dropped test papers are sent out one by one by the rack groove (10).

It is a feature of the present invention that a round bar or a square bar is put in the drum container in the above mechanism. As shown in FIG. 2, the round bar (11) is placed in the drum container (1) and rotated. As shown in FIG. 3, a round bar (1
1) moves while rotating left and right, hits the end of the test strip (8) and pushes the test strip into the inner claw (9) of the drum. Further, as shown in FIG. 4, since the round bar is placed on the test paper (8), the warp of the test paper is straightened by the weight of the round bar and is smoothly fed to the inner claw portion (9) of the drum.

By repeating the above operation, the test paper with large warp could not be taken out from the drum container until now, but the round bar makes the taking out smooth.

[0010]

According to the present invention, the sled of the test paper is round bar,
By removing the square bar due to its own weight and carrying it smoothly to the claw inside the drum, the test paper can be taken out easily. Further, since the rod is simply put in the drum, a complicated mechanism is not required, and the performance of the mechanism can be improved economically and inexpensively.
