[Detailed description of the invention] [Field of industrial application] The present invention relates to a fishing line feeding device for a colony transplanting device, and more specifically, it removes the curl of the fishing line wound around a reel so that it is always in a straight state. It is possible to supply fishing lines, and by realizing this function without complicating the mechanism, and by simplifying the drive mechanism, it is possible to prevent the scattering of dust containing germs and fine metal powder, etc. that occur when the device components are driven. The present invention relates to a fishing line feeding device that prevents contamination caused by these substances.

[Conventional technology]

Screening work is indispensable as a method for collecting useful microorganisms, and devices that automate this work, so-called colony transplant devices, are known, for example, as disclosed in Japanese Patent Application Laid-Open No. 58-201976. .

This device has a structure in which a culture shear dish and a test shear dish are placed on an XY stage, and a pick-up section for performing bacterial fishing is placed above the shear dish. The pick-up section mainly consists of a wire reel wound with fishing line made of gold, aluminum, glass fiber, etc., a feeder, and a clamper. During fishing operations, a thin line as a fishing line is fed out from the wire reel by the feeder. After fixing with a clamper, the tip of the fishing line is cut by a cutter located at the bottom of the fishing bacteria device, and the cut fishing line tip is heated and melted to form a ball-shaped fishing bacteria part, and the fishing bacteria are removed. The department will carry out fishing fungi.

[Problem that the invention attempts to solve]

However, with this device, the fishing line is supplied wound on a wire reel, so the fishing line tends to curl, and this curling tendency is difficult to remove by simply pulling the fishing line. There was a problem in that the end of the fishing line could not be accurately positioned in the colony.

[Means for solving problems]

The present invention was developed in view of the current situation, and it is possible to reliably remove the curl of the fishing line that is fed out from the reel and supply a straight fishing line. The object of the present invention is to provide a fishing line feeding device that can be realized without complication, has fewer moving parts, and can minimize contamination caused by scattering of dust containing germs and fine metal powder caused by the driving of device members. It is.

The present invention that achieves the above object has the following configuration. That is, a fishing line wound around a reel is let out for a predetermined length, the tip of the fishing line is used as a fishing bacteria part, and the colony is bacteria-fished by the fishing bacteria part, and the tip is cut off after the fishing bacteria work. In a fishing line feeding device for a colony transplanting device that feeds out new fishing bacteria, a traction means consisting of a pair of rollers installed opposite to each other is provided on the tip side of the fishing line, and the fishing line is moved between the two rollers. The fishing line is forcibly let out as the roller rotates while being held between the reel body and the reel side, and there is a mechanism on the reel body or the reel side to suppress the amount of the fishing line being let out when the fishing line is forcibly let out by the traction means. The traction means and the braking means constitute a tension control mechanism for the fishing line, and between the traction means and the braking means, a position through which the fishing line passes, It is characterized by being provided with heating means for curl correction.

[Effect]

The fishing line feeding device configured as described above rotates the roller that holds the tip of the fishing line by a predetermined amount while regulating the feeding operation of the fishing line wound on the reel using a braking means. By forcibly pulling and stretching the fishing line to apply appropriate tension to the fishing line, and passing the fishing line under this tension through a heating means, the fishing line is annealed and straightened. It measures the Letting out the fishing line is
This is done with a simple mechanism that simply rotates a pair of rollers holding the fishing line between them, so the fishing line can be continuously fed out while tension is constantly applied to the fishing line. Since the number of moving parts is extremely small, there is almost no scattering of dust containing germs, fine metal powder, etc., and contamination by germs not intended for use can be prevented as much as possible.

〔Example〕

Next, details of the present invention will be explained based on illustrated embodiments. FIG. 1A is a front view of an embodiment of the fishing line feeding device according to the present invention, FIG. 1B is an enlarged view of the main part of the embodiment, and FIG. The device of this embodiment constitutes a part of a colony transplant device, and when used as a colony transplant device, in addition to the fishing line supply device shown in the figure, a fishing line cutting device, an XY stage, an imaging device, an image processing device, etc. is necessary.

The fishing line supply device includes a pedestal 1 that is elongated in the vertical direction.
A support arm 2 is connected to the upper part of the support arm 2.
A reel 5 on which a fishing line 4, which is a monofilament made of synthetic resin, is wound is attached to the base 1 via a mounting mechanism 3, and a traction means 6 for reeling out the fishing line 4 is provided at the lower part of the pedestal 1. A heating means 7 through which the fishing line 4 can be inserted is provided between the reel 5 and the traction means 6. still,
In this example, synthetic resin wire was used as the fishing line, but
Using metal wires such as platinum or aluminum,
Glass fibers can also be used.

As shown in the figure, the mounting mechanism 3 includes a hollow shaft body 9 having a threaded portion 8 at one end passed through the support arm 2, and a locking nut 10 screwed into the threaded portion 8 to attach the hollow shaft body 9. It is fixed to the support arm 2, and the reel 5 is rotatably fitted onto the hollow shaft body 9. The hollow shaft body 9 has a locking head 11 on the base end side.
A screw hole 13 with a threaded portion 12 carved on the inner surface is formed on the distal end side, and a shaft body 15 is inserted through which a collar 14 for preventing slippage is formed on the outer surface of the distal end side.

On the other hand, from the opposite side of reel 5 (right side in the figure),
A reel fixing screw 17 having a knob part 16 is screwed into the screw hole 13 of the shaft body 15 with the inner surface of the knob part 16 in contact with the reel side surface 18. A spring 19 is interposed between the locking head 11 of the shaft body 15 and the base 1, and the grip portion 16 is pulled by the restoring force of the spring 19 in the direction of the arrow in the figure. An appropriate frictional force is applied to the rotation of the reel 5 at the contact surface between the inner surface and the reel side surface 18. This frictional force functions to suppress the fishing line 4 from being let out by the traction means 6, thereby imparting tension to the fishing line 4 and tensioning the fishing line between the reel 5 and the traction means 6. The state is maintained.

The traction means 6 includes a pair of rollers 2 arranged opposite to each other.
A motor 21 is associated with one of the rollers 0 and 20, and the fishing line 4 is held between the rollers 20 and 20 and sent downward, thereby making it possible to feed out the fishing line 4 in units of a predetermined length. A guide pipe 22 is arranged at the bottom of the pulling means 6, and by inserting the fishing line 4 that has passed between the rollers 20 and 20 into the guide pipe 22, the end of the fishing line is moved vertically downward. It guides you accurately.

The heating means 7 is interposed between the reel 5 and the pulling means 6 and heats the fishing line 4 passing between the two.
This is to remove the curl of the fishing line 4 while the fishing line 4 passes through the heating means 7, and in the illustrated example, a hollow heater 23 that is elongated in the direction of movement of the fishing line 4 is used. The heating temperature and heating time by the hollow heater 23 are appropriately determined depending on the material of the fishing line 4.
In addition, what is shown as 24 in the figure is an L-shaped guide for guiding the fishing line 4 to the hollow heater 23.

Although what has been shown above is one embodiment of the present invention, other mechanisms may be used as the braking means, heating means and traction means 6. For example, as a braking means, instead of applying a frictional force to the rotating mechanism of the reel 5, a pair of opposing rollers is provided between the reel 5 and the heating means 7, and the fishing line 4 is inserted between the rollers. At the same time as allowing the fishing line 4 to pass, it is considered that the amount of the fishing line 4 that is fed out may be suppressed by applying a spring pressure or the like to the rotating shaft of the roller to restrict its rotation. Further, the heating means 7 may also have other shapes as long as it can uniformly heat the fishing line 4 along the length of the fishing line.

The operating mode of the illustrated fishing line feeding device is shown below. The fishing line 4 is fed out by rotating the rollers 20, 20 by a predetermined angle every time the transplantation work of colonies of the same bacterial species is completed. The reel 5 on which the fishing line 4 is wound has a reel fixing screw 17 on its side surface that is tightened against the spring pressure of a spring 19.
Since the inner surfaces of the rollers 20 and 20 are in contact with each other, a braking force is always acting on the rotational movement of the reel 5. Therefore, the reel 5 and the roller 20,
This is done by maintaining a straight line without slack for 20 minutes.

The fishing line 4 passes through a hollow heater 23 before passing between the rollers 20, 20, and while the fishing line 4 moves inside the hollow heater 23, it is uniformly heated and annealed. When the fishing line 4 is moved, tension is applied to the fishing line 4, so that the fishing line 4 after passing through the hollow heater 23 has no curling tendency. The straightened fishing line 4 passes through the guide pipe 22, is led out from the lower end of the guide pipe 22, and its end is positioned at a predetermined colony. Note that since the fishing line 4 is straight, the guide pipe 22 can pass through it smoothly.

When a new end of the fishing line is supplied in this way, the end is used for fishing, and when the bacteria of the same species is finished, the end of the fishing line is cut off with a cutter (not shown) and discarded. Then, a new fishing line is sent out again.

When the fishing line 4 wound around the reel 5 runs out, remove the reel fixing screw 16, replace the reel 5, and tighten the reel fixing screw 16 again to fix the reel 5 in a state where it is pressed from the side. It is something.

The fishing line feeding device according to the present embodiment includes a hollow heater 23 disposed between the reel 5 and rollers 20, 20 serving as the traction means 6, and applies tension to the fishing line 4 when the fishing line 4 is let out and maintains the state. Since the underlying fishing line is heated by the hollow heater 23 to perform the annealing treatment, the curl of the fishing line is reliably removed at the stage of being supplied to the rollers 20, 20.

Since the reel fixing screw 17, which prevents the reel 5 from coming off, is given the function of a braking means for controlling the amount of fishing line that is fed out, the braking means can be connected to the fishing line at the same time as the reel 5 is replaced. This makes it extremely easy to set up the device when replacing the reel. Further, since a hollow heater is used as the heating means, it is possible to uniformly heat the fishing line, and there is no fear that the fishing line will bend after hardening, and the fishing line can be reliably straightened.

[Effect of idea]

The fishing line feeding device of the present invention is provided with a traction means consisting of a pair of rollers installed opposite each other in front of the fishing line in the moving direction, and the fishing line is held between the two rollers as the rollers rotate. The reel body or the reel side is provided with a braking means for suppressing the amount of the fishing line that is forcibly fed out by the traction means, and the traction means is configured to be forcibly let out. and the braking means constitute a tension control mechanism for the fishing line, and a heating means for annealing is provided between the traction means and the braking means at a position through which the fishing line passes. Since it is configured,
It is possible to remove the curl of the fishing line while the fishing line moves from the reel to the traction means, and it is possible to always supply the fishing line end in a straight state, making it possible to position the fishing line end in the colony. Accuracy increases dramatically. In particular, since a moderate tension is applied to the heated fishing line, the straightness of the straightened fishing line is extremely excellent.

Furthermore, since the fishing line is decurled by the heating means and is also sterilized at the same time, it is possible to maintain the end of the fishing line in a sterile state, and highly reliable screening operations can be performed.

The fishing line is fed out using a simple mechanism that simply rotates a pair of rollers holding the fishing line between them, so the fishing line can be fed out continuously while maintaining constant tension on the fishing line. can. Since the number of moving parts is extremely small, there is almost no scattering of dust containing germs, fine metal powder, etc., and contamination by germs and the like that are not intended for use can be prevented as much as possible. Furthermore, the amount of fishing line being fed out can be easily changed by simply changing the amount of rotation of the roller, making it easy to control the amount of fishing line consumed. Furthermore, since the mechanism is simple, there are fewer failures and the device cost is low.

Furthermore, since the fishing line straightening process can be carried out by simply adding braking means and heating means to the fishing line feed mechanism of a conventional fishing line feeding device, it is easy to apply this process to conventional devices. The addition of functions has almost no effect on the product price.
