Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cleaner device for a distribution tray in a drug volume dividing device.

[Conventional technology and its problems]

Conventionally, as shown in FIG. 3, a volume dispenser for medicines or the like proposed by Japanese Patent Laid-Open Publication No. Sho 50-91497 is provided on the upper surface of an annular dispenser tray 1 which is rotationally driven in one direction, along the periphery thereof. A concave groove 1a having an arc-shaped cross section is provided, and the concave groove 1a is provided on the upper portion of the distribution tray 1.
It is configured by providing a medicine supplying means 2 for supplying a medicine to 1a and a medicine taking-out means 3 for approaching and separating from a distribution tray, and supplying the medicine to the distribution tray 1 rotated at a constant speed to form a groove on the concave groove 1a. The medicine is uniformly distributed and deposited, and the medicine thus taken out is taken out quantitatively by the medicine taking-out means 3.

In the above capacity dividing device, if the medicine remains attached to the distribution dish after the medicine is taken out, in a continuous capacity dividing operation, an undesired mixed state of the remaining medicine and the medicine to be divided next is generated. There is a problem that occurs and impairs the medicinal effect.

In particular, some of the divided medicines have different properties, and some of them have a high adhesiveness and may adhere strongly to the surface of the distribution dish 1.

To solve such a problem, Japanese Patent Application Laid-Open No. 61-71833 proposes a device for mechanically scraping and discharging solid matter deposited in a container. In this device, a rotary brush is attached to the lower end of a suction extraction pipe, and the rotary brush and the extraction pipe are three-dimensionally moved to scrape and deposit the deposits by suction.

However, although the above-mentioned discharging device is effective for the deposits stationary in the container, it does not have a structure for taking out the chemicals from the surface of the continuously rotating distribution dish, so that the cleaning of the distribution dish is not possible. There is a problem that tends to be enough. That is, even if the medicine is scraped off from the distribution tray by the rotating brush, the medicine scraped off moves together with the distribution tray due to the rotation of the distribution tray and cannot be sufficiently sucked into the extraction tube. In order to completely aspirate the drug, it is necessary to increase the length of the withdrawal tube in the rotating direction of the distribution dish, but this causes a problem of increasing the size of the device.

Further, in the above proposed discharging device, the brush is attached to the vertical rotation shaft so that the brush is rotated about the vertical shaft, but the rotary brush having the above structure is pressed from above into the concave groove of the distribution dish. In this case, there is a problem that the rotation of the rotary brush scatters the drug scraped off and the drug is deposited on the surface of the cleaned groove.

Therefore, this device can mechanically scrape the surface of the distribution dish to remove the adhering drug from the continuously rotating distribution plate, and scatter the scraped drug on the surface of other concave grooves. The aim is to provide a cleaner device that does not run out.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention provides a suction tube that can be moved up and down with respect to the distribution tray in the upper part of the distribution tray, and the suction tube at the tip of the suction tube with respect to the rotation direction of the distribution tray. A rotary brush that rotates in a direction orthogonal to each other, and the outer peripheral shape of the rotary brush is a circular shape corresponding to the arc of the concave groove, and the outer peripheral surface of the rotary brush is the surface of the concave groove at the processing position of the suction pipe. It is formed so as to be in close contact with and in sliding contact with, and on the side surface of the inner suction chamber of the suction tube on the rear side in the rotation direction of the distribution dish, the lower surface has an arc shape, and the lower surface is the surface of the concave groove at the lowered position of the suction tube. A blocking plate that slidably contacts with is provided.

[Operation] In the above structure, the suction tube is lowered onto the distribution dish from which the medicine is taken out by the medicine taking-out means, and the rotary brush and the closing plate are brought into sliding contact with the surface of the groove.

When the rotating brush is rotated while rotating the distribution dish in this state, the drug adhering to the concave groove is scraped off by the rubbing of the rotating brush and sucked. Further, when the scraped medicine tries to move together with the distribution dish, the closing plate fitted in the concave groove stops the backward movement of the medicine and surely sucks it into the suction tube.

In the above structure, since the medicine is scraped off by the rotation of the rotary brush in the direction perpendicular to the rotation direction of the distribution dish, the scraped medicine is not scattered on the cleaned concave groove, and it is ensured. Cleaning can be done.

The disc 11 is formed with a diameter corresponding to the concave surface of the distribution dish 1, and is attached so as to be orthogonal to the rotation direction of the distribution dish 1. On one side of the disc 11, a drug scraping plate 14 is provided.
Is installed. In this take-out means 3, the disk 11 moves up and down on the distribution tray 1, and the disk 11 fits into the concave groove 1a of the distribution tray at the lowered stop position.

As shown in FIG. 2 and FIG. 4 to FIG. 6, the cleaner device 4 can rotate a suction pipe 16 whose rear end communicates with an air suction device through a pipe 15 to the rear part of the rotary shaft 6. The rotary brush 19 is mounted in the suction chamber 17 inside the tip of the suction pipe 16 via the rotary shaft 18. This rotating shaft 18 has a pulley 20
The belt 22 is hung between the pulley 20 and a pulley 21a connected to the brush driving motor 21 fixed to the suction pipe 16 so that the rotation of the motor 21 is transmitted to the rotating brush 19. ing.

The rotating shaft 18 is arranged so as to be orthogonal to the radial direction of the distribution tray 1, and thus the rotating brush 19 is rotated in a direction orthogonal to the rotation direction of the distribution tray 1.

A roller 23 is provided at the rear end of the suction pipe 16, and a pawl cam 24 is mounted on the hoisting shaft 9 so as to face the roller 23. The pawl cam 24 is rotated by driving the motor 8. Then, due to the abutment of the claw cam 24 and the roller 23, the suction tube 16 is
Like the take-out means 3, the rotary shaft 6 oscillates around the fulcrum.

The contact position between the claw cam 24 and the roller 23 is set to the undulating arm 10
It is set so as to be out of phase with the contact position between the roller 13 and the claw cam 12, and when the undulating arm 10 descends and the disk 11 of the take-out means 3 contacts the distribution tray 1, the suction tube 16 is It is located in the middle of the downward movement, and after the disk 11 contacts the distribution tray 1, the rotary brush 19 contacts the distribution tray 1 after a predetermined interval.

The suction chamber 17 is formed in a disk container shape so as to house the rotating brush 19, and a suction port 25 is provided on the lower surface along the shape of the distribution dish 1. Further, a closing plate 26 such as a synthetic resin plate is attached to an end surface 17a of the suction chamber 17 on the rear side with respect to the rotation direction of the distribution tray 1, and the lower surface of the closing plate 26 is at a lowering stop position of the suction pipe 16. It contacts the concave groove 1a of the distribution dish 1 and is formed in an arc shape so as to match the surface shape of the concave groove 1a.

The rotating brush 19 has brushes 28 on the outer peripheral surface of the disk 27 at predetermined intervals.
The outer peripheral shape formed at the tip of each brush 28 is formed in a circular shape so as to match the diameter of the circular arc in the concave groove 1a of the distribution tray 1. Further, a part of the lower side of the brush 28 protrudes from the suction port 25 of the suction chamber 17 to the outside, and is fitted into the distribution tray 1 at the lowering stop position of the suction pipe 16.

This embodiment has the above-mentioned structure, and its operation will be described below.

As shown in FIG. 1, when the medicine is evenly distributed and accumulated on the distribution tray 1 and then the medicine is divided and taken out, the motor 8 is rotated while the distribution tray 1 is rotated in one direction at a constant speed. Is driven to rotate the shaft 9 for raising and lowering, and the medicine take-out means 3 and the cleaner device 4 are lowered. In this case, the motor 7 is driven to rotate the disk 11 of the extracting means 3 and the brush driving motor 21 is driven to rotate the rotary brush 19, and at the same time, the inside of the suction pipe 16 is sucked by the air suction device. .

After the disc 11 of the take-out means 3 comes into contact with the concave groove 1a of the distribution tray 1 due to the phase shift provided between the claw cams 12 and 24 as described above, a rotary brush is provided with a predetermined interval. 19 and the closing plate 26 contact. That is, first, the disk 11 is fitted into the concave groove 1a of the distribution tray 1 to stop the moving medicine, and the scraping plate 14 scrapes the medicine and discharges it to the discharge chute 27.
After the surface portion of the distribution tray 1 from which the medicine has been taken out moves backward, the rotary brush 19 comes into contact with the surface of the concave groove 1a to start cleaning. Therefore, the chemicals deposited by the cleaner device 4 are not inadvertently sucked.

The surface of the concave groove 1a from which the medicine is taken out by the taking-out means 3 is
In the cleaner device 4, the rotating brush 19 mechanically brushes the adhered medicine to scrape it off, and the medicine is sucked by the air suction of the suction chamber 17.
In addition, a blocking plate 26 is provided behind the suction port 25 and has a concave groove 1 a in the distribution tray 1.
Since the medicine rubbed off by the rotating brush 19 is stopped from moving backward by the closing plate 26, all the medicine rubbed off by the rotating brush 19 is sucked into the suction chamber 17.

Furthermore, as shown in FIG.
Since it rotates in a direction orthogonal to the rotation direction of the drug, the drug in the concave groove 1a is scraped off to the outside in the radial direction of the distribution dish 1, and is sucked into the suction pipe 15 through the suction chamber 17. Therefore, the medicine adhering to the surface of the distribution dish 1 can be reliably removed, and it is possible to prevent the residual medicine and the medicine to be divided next to be mixed on the distribution tray 1.

When the distribution tray 1 makes almost one rotation and the entire surface thereof is clean run, the motor 8 is reversely rotated to raise the take-out means 3 and the cleaner device 4, and the distribution work is started again.

In addition, in the embodiment, the cleaner device 4 and the take-out means 3 are provided on the same rotary shaft 6 so as to be raised and lowered, but the cleaner device 4 may be provided on the table 5 separately from the take-out means 3.
