Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] In the present invention, for example, in order to analyze or test a liquid under test such as blood, the above liquid is added to perform a dispensing process as a pretreatment. The present invention relates to a belt conveyor type test tube transport device used for transporting a test tube from one place to another place.

[Prior Art] FIG. 4 is a front view showing the configuration of a conventional belt conveyor type test tube transporting device of this type, and FIG. 5 is a partially cut-away view of a cylindrical rack for holding test tubes in the above device. FIG. In FIGS. 4 and 5, reference numeral 1 is a belt conveyor, which is driven and moved in a direction perpendicular to the paper surface by a small motor (not shown). Reference numerals 2 and 3 are a pair of guide rails, which are arranged on both sides of the belt conveyor 1 so as to face each other, and are arranged in parallel along the conveyance direction of the conveyor 1. Reference numeral 4 denotes a cylindrical rack for holding the test tube, which is made of synthetic resin or the like, and has an annular engagement groove 4a and a stopper engagement groove 4b for preventing falling, which are provided on the outer peripheral surface thereof. Thus, in this cylindrical rack 4, the annular engaging groove 4a for preventing the tipping is engaged with the guide edges 2a and 3a provided at the upper end portions of the guide rails 2 and 3 by the conveyor belt 1 and the paper surface. It can be transported in a direction perpendicular to. Note that the stopper engagement groove 4b temporarily moves the cylindrical rack group subsequent to the predetermined cylindrical rack 4 during the transportation when a large number of cylindrical racks 4 are continuously transported by the belt conveyor 1. It is a groove for inserting a rod-shaped stopper when it becomes necessary to stop it. A test tube insertion hole 4c and a bottom penetrating small hole 4d are provided in the axial center of the cylindrical rack 4 so that the test tube 5 can be stably inserted into the insertion hole 4c. Reference numeral 5a is a plug for closing the opening of the test tube.

[Problems to be Solved by the Invention] In the conventional belt conveyor type test tube transporting device having the above-mentioned configuration, the annular engaging groove 4a of the cylindrical rack 4 is provided on each of the guide edges 2a and 3a of the guide rails 2 and 3. Since they are engaged, there is no risk of the cylindrical rack 4 falling over. However, the cylindrical rack 4 vibrates or resonates on the rack mounting surface of the belt conveyor 1 due to the vibration of the belt conveyor 1 during conveyance. In particular, when the test tube 5 is inserted in the cylindrical rack 4, the test tube 5 is united with the cylindrical rack 4 and the center of gravity is increased, so that the vibrations and the like are amplified. Therefore, there is a problem in that the conveyance cannot be performed stably. As means for suppressing the above-mentioned vibration and the like, the gap between the guide edges 2a and 3a and the annular engagement groove 4a is made small, or the cylindrical rack 4 is pressed by a spring onto the rack mounting surface of the belt conveyor 1. The means of can be considered. However, if the above means is taken, running resistance will occur in the cylindrical rack 4, and various problems will newly occur.

Therefore, the object of the present invention is to minimize vibration and resonance of the cylindrical rack during transportation, to perform stable test tube transportation, and to prevent running resistance from occurring in the cylindrical rack. An object of the present invention is to provide a belt-conveyor type test tube transfer device capable of various transfers.

[Means for Solving the Problems] In order to solve the above problems and achieve the object, the following means were taken. That is, a guide rail is arranged along the conveyance direction of the belt conveyor, and with respect to this guide rail,
A cylindrical rack for holding a test tube is provided so as to be conveyed by the belt conveyor in a state where an annular engaging portion provided on the outer peripheral surface is engaged. Then, a first magnetic attraction member such as a disk-shaped permanent magnet is provided on the bottom surface of the cylindrical rack. Further, in parallel with the rack mounting surface of the belt on the belt conveyor, and facing the first magnetic attraction member with a minute gap therebetween so that a magnetic attraction force acts between the first magnetic attraction member. As described above, a second magnetic attraction member such as a soft magnetic iron plate is provided.

[Operation] As a result of taking the above means, the following operation occurs. The cylindrical rack for holding the test tube is adsorbed in a “perfect” close contact state on the rack mounting surface of the belt conveyor by the magnetic attraction force of the first magnetic attraction member and the second magnetic attraction member. Therefore, vibration and resonance of the cylindrical rack during transportation can be suppressed to a minimum, and the test tube can be transported stably. Further, since the first magnetic adsorbent and the second magnetic adsorbent are arranged so as to face each other with a minute gap therebetween, the magnetic attractive force itself is reduced as compared with the case where both are directly adhered. However, sliding friction does not occur between them. Therefore, there is no risk of running resistance in the cylindrical rack, and smooth transportation is possible.

[Embodiment] FIGS. 1 to 3 are views showing an embodiment of the present invention, FIG. 1 is a partially cutaway perspective view showing the constitution of the apparatus main body, and FIG. 2 shows the same constitution. The front view shown in FIG. 3 and FIG. 3 are side views showing the structure of the cylindrical rack 4 partially broken away. The fourth
The same parts as those in FIGS. 5 and 5 are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIGS. 1 to 3, on the bottom surface of the cylindrical rack 4 for holding the test tube, a disk-shaped permanent magnet 14 as a first magnetic attraction member is flush with the bottom surface of the cylindrical rack 4. It is buried so that it becomes "state." The magnet 14 may have a ring shape or the like.

On the other hand, as shown in FIG. 1 and FIG. 2, the belt conveyor of this embodiment includes a belt conveyor 11 and a belt conveyor 1.
It is divided into two parts. A soft magnetic iron plate 13 as a second magnetic attraction member is arranged between the two-divided belt conveyors 11 and 12. The surface of the iron plate 13 is designed to be G lower than the rack mounting surfaces of the two-divided belt conveyors 11 and 12. Thus, the iron plate 13 and the magnet 14 provided on the bottom surface of the cylindrical rack 4 placed on the two-divided belt conveyors 11 and 12 have a magnetic attraction force so that a magnetic attraction force acts between them.
They are arranged parallel to the rack mounting surfaces of 1 and 12. Moreover, it is arranged so as to face the magnet 14 with a minute gap G therebetween.

In addition, as shown in FIG. 1, the test tube 5 containing the liquid L to be tested is attached to the belt conveyer 11,
A mechanism (not shown) for automatically inserting / removing the cylindrical rack 4 on 12 is attached as shown by arrows A and B.

Next, the function and effect of the apparatus of this embodiment configured as described above will be described. When the test tube 5 is inserted into the cylindrical rack 4 as indicated by arrow B in FIG. 1 and a motor (not shown) is operated, the belt conveyors 11 and 12 are transferred and driven in the direction of arrow C. Then, the belt conveyors 11 and 12
The cylindrical rack 4 mounted on the rack mounting surface is also transported in the direction of arrow C. At this time, the cylindrical rack 4 is attracted to the rack mounting surfaces of the belt conveyors 11 and 12 in a “perfect” close contact state by the magnetic attraction between the magnet 14 and the iron plate 13. Therefore, the vibration and resonance of the cylindrical rack 4 during traveling can be suppressed to the minimum. As a result, the test tube can be stably transported. Further, since the magnet 14 and the iron plate 13 are arranged so as to face each other with a minute gap G therebetween, the magnetic attraction force itself is reduced as compared with the case where the both are directly adhered, but sliding friction occurs between them. There is no such thing. Therefore, the cylindrical rack 4
There is no risk of running resistance, and smooth transportation is possible.

The present invention is not limited to the above embodiment.
For example, in the above embodiment, the magnet 14 is used as the first magnetic attraction member and the iron plate 13 is used as the second magnetic attraction member, but the relationship between the magnet and the iron plate may be reversed. Both may be composed of magnets. Further, in the above-described embodiment, the engaging groove 4a formed of an annular concave groove is used as the annular engaging portion.
The guide edge 2 of the guide rails 2 and 3
Although an example of engaging with a and 3a has been shown, an engaging protrusion formed of an annular ridge is provided as an annular engaging portion, and the engaging protrusion is engaged with the guide groove provided in the guide rails 2 and 3. May be. Further, in the above-mentioned embodiment, the belt conveyor is divided into two and the iron plate 13 is arranged in the middle thereof, but a long iron plate may be arranged on both sides or one side of the belt conveyor. Of course, various modifications can be made without departing from the spirit of the invention.

[Advantage of the Invention] According to the present invention, a first magnetic attraction member made of a magnet or the like is provided on the bottom surface of a cylindrical rack, and a second magnetic attraction member made of an iron plate or the like is provided in parallel with the rack mounting surface of the belt conveyor. Since the cylindrical rack is attracted to the rack mounting surface of the belt conveyor by the magnetic attraction force of both members,
A belt that can suppress vibration and resonance of the cylindrical rack during transportation to the minimum, can stably transport the test tube, and there is no risk of running resistance in the cylindrical rack, and a smooth transport belt. A conveyor-type test tube carrier can be provided.
