Abstract

(57) [Summary] [PROBLEMS] The present invention requires automatic unmanned sampling from a plugged bottle and sending of sample water to the analyzer main body in order to make the BOD automatic analyzer an unmanned operation device. is there. In order to automatically take a sample from this flask, automatically remove the stopper from the flask and automatically remove the stopper. . That is the issue. The present invention has a mechanism in which a holding plate is placed on the head of a blanket, a sliding plate is inserted under the neck of the stopper starting from the holding plate, and the sliding plate is vertically pulled up by an air cylinder. In addition, the head of the blank bottle stopper is held by a plate with a spring. Further, a guide plate is provided below the stopper opening mechanism. In addition, the material of the stopper of the bottle will be made of Teflon. The problem was solved by things like that.

Description

[Detailed description of the invention]   [0001] [Technical field to which the invention belongs] The present invention relates to an automatic analyzer for analyzing BOD (biochemical oxygen consumption). Automatic analyzer that performs BOD analysis unattended on holidays such as Saturday and Sunday Automatically removes the stopper from the culture bottle (hereafter referred to as "Franbin") for culturing the sample. The present invention relates to a device for returning the stopper in a specific manner.   [0002] [Prior art] In BOD analysis, a large amount of blisters are automatically handled and the sample water in them is automatically removed. Saturday because there is no automatic bottle opener required to collect water An automatic analyzer that performs BOD analysis unattended on holidays such as Sunday has not been developed . In addition, since the bottle is made of glass and the stopper is also made of glass, there is no problem of damage. Nobody thought of an automatic bottle opening mechanism. In addition, automatically remove plugs There was no idea of returning.   [0003] [Problems to be solved by the invention] In order to make the BOD automatic analyzer an unmanned operation device, the sample It is necessary to automate from where the fee is taken. For that, for culture Samples are automatically collected from the plugged blanks and sent to the analyzer. Need to water. To automatically sample water from this bottle, It is necessary to automatically remove the stopper automatically. Pull the plug off and let it stand by After the BOD analysis is completed, return the stopper to the original flask and return to the final step with the stopper in the stoppered state. Is done. Therefore, the stopper of the balloon is automatically removed automatically and automatically after analysis. Devising a mechanism to return to the empty bottle, usually both the empty bottle and the stopper are made of glass Therefore, it is an issue to take anticipated damage measures.   [0004] [Means for Solving the Problems] In the present invention, a holding plate is placed on the head of the bottle, A mechanism to insert an id plate and lift it vertically by an air cylinder was adopted. In addition, the head of the blanket stopper is held by a plate with a spring. Further, a guide plate is provided below the stopper opening mechanism. Next, in the bottle The material is made of tephro (substance name is polytetrafluoroethylene). To things Therefore, the problem was solved.   [0005] [Embodiment of the invention] In the present invention, the starting point of pulling out the stopper is first applied to the blank head at I decided to. Insert the slide plate into the gap between the top of the bottle and the stopper Place the slide plate on the lower part of the neck of the I decided to pull it out vertically. Furanbin is developed by our company in the pre-process. 4 samples are diluted at the same time by an automatic dilution device and sent to the BOD automatic analysis process. Therefore, four specimens were simultaneously extracted for four specimens. This number can be 3 or 4 However, it is set as an appropriate number of automatic analyzers. The stopper is pulled out Therefore, the head of the stopper may be spring loaded It was structured to be held down by This makes it easy to return the stopper to the original bottle You can do it. Next, adjust the position of the bubble to the stopper automatic withdrawal mechanism. The adjustment is performed by three-dimensional movement of the cassette on the top and bottom and left and right. However, the bottles in the cassette are arranged in a dish-shaped metal cassette of 24 pieces. The center of the fragrance may be slightly shifted due to the degree of A guide plate was provided below to correct the position of the bottle. In addition, damage Various materials other than glass were examined to minimize them, but the accident rate and analysis accuracy were affected. The material of the stopper was made of Teflon because it does not affect. Unmanned and automatic Stable pull-out became possible.   [0006] 【Example】 Hereinafter, an embodiment will be described with reference to the accompanying drawings. In Fig. 1, the blank holding plate In (11), four openings are provided on a plane. The size of the opening is the maximum diameter of the stopper It must be sufficiently large and smaller than the maximum diameter of the head of the balloon. In addition, holding plate ( 11) is a slide rail (3) of an upper pull-out mechanism having an air cylinder (1). Connected via slide receiver (9). The bottle opener (8) is a gourd-shaped flat When the plug has passed through the plug in the vertical direction with the opening having a large opening, Ride and insert the head of the stopper into the smaller opening. It is structured to be pulled up by the air cylinder (1). This bottle opener (8 ) Is provided with a plug head holding plate (7) with a plug holding spring (6). Figure 2 FIG. 2 shows a cross-sectional view of the mechanism. FIG. 2 shows a state in which a bottle opener is inserted in the process I. . In step II, unplug the plug and lower the bubble to move it laterally. Indicates the machine status. FIG. 3 shows the opening of the bottle opener plate (8) and the bulge holder plate (11). And the relationship between the stopper and the head of the bottle. In FIG. 3, step I is the opening of the opener. This shows a state where the stopper of the bulb has been passed through to the part having a larger diameter. Step II is bottle opener The plate is slid and fitted into the smaller opening. Bottle opener in this state The plug can be withdrawn by lifting the plate vertically.   [0007] [Effect of the invention] As described above, the automatic bottle opener of the present invention is assembled with the BOD automatic analyzer. It was possible to make unmanned driving on holidays possible. Of course the BOD Automated analyzers are able to assemble lots of analytes on normal work days. This can be used as labor-saving equipment.
