Description

[Detailed explanation of the invention] (Industrial application field) This invention is based on a developed wet disc film that is attached and rotated at high speed (so-called spin squeeze) to remove the developed film that is attached to the disc film. This invention relates to a liquid draining device for quickly centrifuging liquid components.

(Prior art) This type of liquid draining device has a structure in which the motor section, magazine section, and tank section can be separated from each other for operational purposes, and the shaft of the magazine section on which the disk film is attached is efficiently rotated at high speed by a small motor. In this system, the rotational force of the motor shaft is transmitted by engaging the shaft part at a location away from the axis, and a bearing is used in the bearing part of the shaft to ensure smooth rotation.

However, using a bearing in the bearing part increases costs, and to improve this, it is possible to use a metal part (bearing), but the metal part can be easily damaged due to the influence of the drug in the developing solution. A resin metal (bearing) is used to prevent corrosion, and a gap is provided between the bearing and the shaft to avoid seizure due to frictional resistance during high-speed rotation.

This play due to the gap in the resin metal (bearing) part causes the shaft to run out during rotation, and this vibration not only impedes efficient, smooth high-speed rotation, but also causes uneven wear in the metal (bearing) part. It also had the disadvantage of generating vibration and noise.

(Problem to be solved by the invention) This invention fixes the shaft of the disc film liquid drainer during high-speed rotation without affecting the rotational force (frictional resistance).
The purpose is to eliminate runout when the shaft rotates, eliminate the uneven bearing phenomenon, vibration, and noise, realize efficient high-speed rotation transmission, and improve the draining efficiency of this type of equipment. do.

(Means for solving the problem) This idea involves a shaft supported by a metal (bearing) part, engaged with the motor at an eccentric part so as to face inside the liquid draining tank, and a disk film attached to the tip of the shaft to rotate it. In a device that removes liquid by centrifugal force, there is a
Rotary plates facing each other are provided, and a fitting part consisting of a protrusion is provided at the center (on the axis) of one rotating plate surface, and a fitting part consisting of a protrusion is provided oppositely at the center (on the axis) of the other rotating plate surface.
are each provided with a fitting portion consisting of a receiving hole, and a hooking portion consisting of an elbow plate is provided at the eccentric portion on one rotary plate surface, and a pin is provided at the eccentric portion on the opposite rotary plate surface. The two protrude from each other, and the mating parts are mated against each other on the same axis, so that when rotating, the engaging part on the motor shaft side hooks the engaging part on the shaft side horizontally in the direction of rotation. The spin-squeeze mechanism in the disk film development processing apparatus, which is characterized by the following characteristics, prevents the shaft from shaking during rotation, and realizes smooth and efficient high-speed rotation transmission.

(Function) By fitting the fitting portions of the shaft and the motor shaft provided on the opposing rotary plate surfaces in abutting manner on the same axis, and fitting the fixed motor shaft to the shaft, Completely prevents vibration with respect to the axis when the shaft rotates.

The engaging part on the shaft faces the engaging part on the motor shaft at the eccentric part during rotation, and the engaging part on the shaft is hooked horizontally in the direction of rotation and pushed around to rotate the shaft, so it rotates without causing unnecessary frictional resistance. In addition to being able to efficiently transmit power, just by fitting the motor shaft and shaft and starting, the engaging part of the motor shaft naturally engages with the engaging part of the shaft, immediately transmitting rotational force. .

Moreover, since the shaft rotates at the same rotation speed as the motor shaft and rotates synchronously in the same direction, frictional resistance is prevented from occurring at the fitting portions.

(Example) Next, a specific example of the spin squeeze mechanism according to this invention will be described with reference to the drawings.

Fig. 1 is a partially cutaway perspective view of a disk film development processing apparatus that can implement this invention;
The figure shows an exploded perspective view of the main parts of the same. In the figure, 1 is a liquid draining device, which is made up of a motor section 2, a magazine section 6, and a liquid draining tank section 13.

The motor part 2 has a rotating plate 3 fixed on the rotating shaft of a motor 2a installed in a case 2b with one side open, and a protrusion 5 made of an elastic material such as rubber in the center of the surface of the rotating plate 3. Each elbow plate 4 is provided in a protruding manner.

The magazine section 6 supports a shaft 7 vertically and slidably in a light-shielded state with a bearing 8 made of resin metal at the upper part.A rotary plate 10 facing the rotary plate 3 is fixed to the upper part of the shaft 7. A receiving hole 9 into which the protrusion 5 is fitted is provided at the center of the 10th surface, and a pin 11 is protruded from the eccentric portion so as to be hooked to the elbow plate 4 in the horizontal direction.

After attaching the disk films 12, 12 to the lower part of the shaft 7 of the magazine section 6, a rotary motion transmission member connected to a motor built in the processor main body (not shown) is hooked to the pin 11 of the magazine section 6.
The magazine section 6 is connected to a processing tank (not shown) and performs a series of development processing. After that, magazine section 6
is removed from the processing tank, and the disc films 12, 12 wetted with the processing liquid are placed in the liquid draining tank part 13 and mounted.

The protrusion 5 of the motor section 2 is fitted into the receiving hole 9 of the magazine section 6 to connect the magazine section 6 to the motor section 2, and the pin 1 with which the elbow plate 4 faces when the motor is started.
1 horizontally in the direction of rotation, while controlling the runout due to play in the bearing shaft 8 of the shaft 7.
The rotational force of the motor 2a is transmitted to the shaft 7 to rotate it efficiently, and the processing liquid adhering to the disk film 12 is detached by centrifugal force.

In the above embodiment, the elbow plate 4 is connected to the motor section 2.
Although the explanation has been given on the case where the arm plate 4 and the pin 11 as the engaging parts in this invention are provided protruding widely across the surface of the rotary plate 3, the magazine part 6 is rotating plate 1
The same effect can be obtained by providing narrow protrusions opposite to each other on the rotational orbit of the pin 11 on the zero plane.
Of course, the functions and effects of the elbow plate 4 or pin 11 of the engaging part, and the protrusion 5 or receiving hole 9 of the fitting part are the same regardless of whether they are provided on either of the rotary plates 3 or 10.

In addition, we have discussed a method in which the disk film 12 attached to the lower part of the shaft 7 of the magazine section 6 is developed in a processing tank (not shown) and then separately attached to the liquid draining tank section 13. After the final processing is completed, the processing liquid in the processing tank is drained, and the motor section 2 is installed at the top of the magazine section 6 in that state.
A method is also possible in which the liquid components adhering to the disk film 12 are separated by bonding.

(Effects of the invention) As explained above, the disk film developer draining device of this invention has a fitting part (bearing part) that connects and supports the shaft part to the motor shaft part in abutting manner, and a part that transfers the rotational force of the motor shaft to the shaft part. The engaging parts for transmitting information to the parts are provided separately on each other's rotary plates, eccentric to the shaft center, and the engaging parts are mounted on each other's rotating plates so that the engaging parts engage horizontally along the rotational direction as the motor shaft rotates. It is characterized by its prominent location.

Therefore, the motor shaft part and the shaft part that are fitted and connected by the engaging parts that are spaced apart from the axis and protrude on the same rotational orbit facing each other, the engaging part on the motor shaft side that rotates when the motor is started is connected to the shaft part. Because the transmission is transmitted by automatically and reliably engaging and pushing the side engaging parts, it is possible to easily and efficiently transmit rotational force without causing frictional resistance on the mutually contacting surfaces unlike when fitted or connected. To easily and reliably connect and separate a motor shaft part and a shaft part without the trouble of engaging each other's engaging parts, thereby increasing the efficiency of liquid draining work.

In particular, the fitting part (bearing part) that connects and supports the motor shaft part and the shaft part avoids the influence of frictional resistance from the engaging part that transmits rotational force, and the motor shaft part and the shaft part are fitted in a butt-like manner. In this state, they rotate in the same direction and at the same rotational speed, as if on the same body axis, so no rotational frictional resistance occurs. As a result, the fitting parts fit tightly together during rotation, preventing the shaft from swinging, resulting in extremely smooth, light, and high-speed rotation.This improves the efficiency of removing liquid (water) from the disk film by utilizing centrifugal force.
It also increases durability without loosening and rattling even after long-term use.

Furthermore, this fitting configuration makes it possible to fully utilize the gap (play) provided between the motor shaft and the metal (bearing) part of the shaft.
This greatly helps to suppress uneven wear, vibration, and noise in the metal (bearing) part.

It has many effects in the spin squeeze mechanism of disk film.
