Description

[Detailed Description of the Invention] The present invention relates to a culture medium smoothing device, and more particularly to an automatic smoothing device that smooths the top surface of a culture medium after dispensing it into a shear dish.

Generally, the culture medium dispensed into a shear dish is solidified by blowing cold air as appropriate, but in the past, this solidification was simply carried out by static conveyance.
As a result of solidification while the culture medium is not spread evenly within the shear dish, it is inevitable that defects such as donut formation, in which a depression is formed in the center, and cut-off phenomenon, in which depressions are formed in the periphery, often occur. It was hot.

Therefore, the inventor of the present invention has made extensive studies to resolve such conventional defects, and has found that by transporting the shear dish with a slight tilt after dispensing the medium,
The present invention has devised a medium smoothing device in which the top surface of the medium is a smooth surface.

That is, the present invention is a culture medium smoothing device characterized in that guide rails for supporting and guiding a shear dish are installed on both sides of a chain conveyor for conveying a shear dish, and projections are appropriately formed on both guide rails.

The present invention will be further explained below along with drawings showing one embodiment thereof.

Reference numeral 1 denotes a chain conveyor for conveying a shear dish, and a pair of guide rails 2 for supporting and guiding the shear dish are installed on both sides of the chain conveyor. This guide rail 2 is composed of a horizontal guide part 3 that supports the outer bottom part of the shear tray 6, and a vertical guide part 4 that supports the outer wall part of the shear tray 6. It is installed so that it is at the same position as the top surface of the Note that the guide rail 2 may have an L-shaped end surface when the devices of the present invention are installed in a single row, but when multiple devices are installed in parallel, two guide rails, a horizontal guide member and a vertical guide member, may be used.
A layered structure is advantageous because a single guide rail can be used on both the left and right sides as guide rails.

Reference numeral 5 denotes a protrusion formed on the guide rail 2, which is formed so as to protrude slightly upward from the horizontal guide portion 3 of the guide rail 2. The shape of this protrusion may be any shape as long as it does not stop the shear conveyance, in other words, the shear 6 can climb over it, but it is preferable to make it arcuate or trapezoidal with a gentle slope. Preferably, the degree of protrusion is the same as that of the horizontal guide portion 3.
It is effective to set it at a distance of about 3 to 8 mm from the top surface.
The protrusions 2 may be formed on the guide rail 2 at appropriate intervals, but in this case, if they are formed alternately on the left and right guide rails at intervals equivalent to one shear plate, the shear plate 6 can be tilted. Since it is possible to transport the shears while changing their direction to some extent,
This is advantageous because the medium can be smoothed more effectively. Note that the protrusions 2 may be a simple plate when the devices of the present invention are installed in a single row, but when multiple devices are installed in parallel, it is recommended that the protrusions 2 have a concave structure that fits downwardly into the guide rail 2. Advantageously, the projections can each be used as a projection.

As described above, the present invention is constructed. According to the present invention, the shear tray 6 is appropriately tilted during conveyance by the protrusion 5 formed on the guide rail 2, so that the dispensed medium is The particles are averaged in the shear tray 6 and solidified to form a smooth surface, thereby preventing the production of defective products as in the past.
