Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a cleaner device for divided masses in a rotary distribution device.

[Conventional technology]

A large number of divided masses extending in the radial direction of the distributor are formed in an annular shape on the outer periphery of a circular distributor that is rotationally driven in one direction, and when the distributor is rotated, a fixed amount can be distributed within the required number of divided masses. supply drugs,
There has been a rotary dispensing device in which the opening/closing lids of the lower openings of the divided cells are sequentially opened at a position in front of the supply position in the rotational direction, and the medicine inside is discharged downwards (Utility Model No. 56- (See Publication No. 53001).

In the above-mentioned rotary dispensing device, the properties of the chemicals handled are different, and some of the chemicals are highly adhesive, so when the opening/closing lid is opened to discharge the chemicals in the divided compartments, In some cases, medicine may remain in the divided cells, and if the next medicine is supplied in this state, the remaining medicines will mix, which is extremely problematic.

In order to solve this problem, the applicant of the present invention attempted to remove the remaining drug by opening the opening/closing lid at the bottom of the divided compartment and applying an absorbing force inside the divided compartment from the opening.

[The problem that the idea attempts to solve]

However, in the method of removing the residual drug by suction, if the drug is strongly adhered to the inner surface of the divided mass and the upper surface of the opening/closing lid, there is a problem in that it is not possible to completely remove the adhered substances.

The object of this invention is to provide a cleaner device that can reliably remove deposits from the inner surfaces of the divided boxes and the upper surface of the opening/closing lid.

[Means to solve the problem]

In order to solve the above problem, in this invention, a lid opening/closing mechanism is provided that opens the opening/closing lid at a position on the front side in the rotational direction from the medicine discharge position, and the upper and lower ends are supported around the distributor. A first arm is provided with an arm support shaft, is supported so as to be able to rise and fall freely along this arm support shaft, and is moved up and down by an elevating mechanism.
The rear end of a second arm is swingably connected to the tip of the arm, and the second arm has a tip that faces above the divided square with the opening/closing lid opened, and a rear end of the second arm that faces both sides of the divided square. a rotation mechanism that rotatably supports a rod-shaped flexible cleaning tool having an outer diameter that can be contacted with the cleaning tool; a cam mechanism that rotates the first arm around an arm support shaft; A configuration was adopted that included a cam mechanism that allowed the arm to swing at a predetermined angle.

[Effect]

In the cleaner device having the above configuration,
When the opening/closing lid is opened by the lid opening/closing mechanism, the first
The arm is lowered and a cleaning tool that rotates in one direction is inserted into one end within the divided mass. When the lower end of the cleaning tool comes down to the position where it touches the top surface of the opening/closing lid,
The first arm is rotated about the arm support shaft by the operation of the cam mechanism, and at the same time, the second arm is oscillated by the operation of the cam mechanism, and the cleaning tool is moved toward the other end of the divided mass.

In this way, the cleaning tool that rotates in one direction moves from one end of the divided compartment to the other end while being inserted into the divided compartment, so it adheres to the inner surface of the divided compartment and the top surface of the opening/closing lid. The deposits are removed by contact with the cleaning tool.

〔Example〕

As shown in the figure, on the outer periphery of the circular distributor 1, a large number of divided squares 2 extending in the radial direction of the circular distributor 1 are formed in an annular shape. As shown in FIG. 1, the end portion is rotatably supported by a pin 4 and pulled up by a spring 5 to close the lower opening of the divided mass 2.

The distributor 1 is rotated in the direction of the arrow in FIG. 2 by a rotary drive device (not shown), and during the rotation, the drug is supplied into the required number of divided cells 2 by a drug supply device (not shown). . Further, the medicine in the divided mass 2 is dropped and discharged at a predetermined position by opening the opening/closing lid 3.

The distributor 1 may be rotated intermittently using the formation pitch of the divided masses 2 as a feeding pitch, or may be rotated in one direction at a constant speed. In the illustrated embodiment, it is rotated in one direction at a constant speed.

As shown in FIG. 1, an opening/closing guide 6 for guiding the movement of the end extending inward from the rotational support portion of the opening/closing lid 3 is provided at a position in front of the drug discharge position in the divided mass 2 in the rotational direction.

1 is provided. As shown in FIG. 2, the rotating frame 11 has two guide rods 12 parallel to the arm support shaft 10, and the end of the first arm 13 is slidable along the guide rods 12 and the arm support shaft 10. is supported by The first arm 13 extends long in the tangential direction of the outer circumference of the distributor 1,
A shaft 14 provided at the rear end of the second arm 15 is rotatably supported at its tip. 2nd arm 1
Reference numeral 5 extends in the radial direction of the circular distributor 1, and a cleaning tool 16 is attached to the distal end facing above the outer end of the divided mass 2. This cleaning tool 16 is made of a flexible material such as sponge, and its outer diameter is larger than the maximum width of the divided mass 2.

At the bottom of the bracket 9, a transmission shaft 17 rotatably driven by a motor is connected to the arm support shaft 1.
0, and the rotation of the transmission shaft 17 is
Arm support shaft 10 via a pair of bevel gears 18
is transmitted to. Further, the rotation of the arm support shaft 10 is transmitted to the cleaning tool 16 via a gear transmission mechanism 19 provided inside the first arm 13 and the second arm 15 (see FIG. 1).

The first arm 13 is rotated by a first cam mechanism X around the arm support shaft 10 by a set angle. As shown in FIG. 3, the first cam mechanism X has a surface cam 20 attached to a transmission shaft 17, and
A push rod 21 is provided between the cam surface of the rotary frame 11 and one guide rod 13 of the rotary frame 11, and as the surface cam 20 rotates, the push rod 21 is moved in the axial direction, and the first arm 13 is moved together with the rotary frame 11. Support shaft 1
I try to rotate it around 0.

Note that 22 in FIG. 3 indicates a spring that deflects the rotating frame 11 in one direction and presses the end of the push rod 21 against the surface cam 20.

Further, the first arm 13 is raised and lowered by the raising and lowering mechanism Y. As shown in FIG. 1, the elevating mechanism Y has a disk 25 fixed to the tip of a drive shaft 23 which is rotatably supported by a bracket 9 and through which rotation of the transmission shaft 17 is transmitted via a gear mechanism 24. An eccentric pin 26 provided on the outer periphery of the disc 25 is connected to the first arm 13 by a crank rod 27, so that the rotation of the disc 25 causes the first arm 13 to move up and down.

Furthermore, the second arm 15 is oscillated about the shaft 14 by the second cam mechanism Z. As shown in FIGS. 1 and 2, the second cam mechanism Z includes a cam follower attached to one end of a deflection arm 29 on the outer periphery of a cam 28 that is attached to the upper part of the arm support shaft 10 and rotates together with the arm support shaft 10. A pin 32 provided on the upper surface of the first arm 13 is inserted into a long hole 31 formed in the longitudinal center of the deflection arm 29, so that the deflection arm 29 is slidably supported. Further, the other end of the deflection arm 29 is connected to the second arm 15 via a pin 34,
Due to the rotation of the cam 28, the second
The arm 15 is made to swing at a predetermined angle.

Note that 33 represents a spring that deflects the second arm 15 in one direction and brings the cam follower 30 at the end of the deflection arm 29 into contact with the cam 28 .

The cleaner device shown in the embodiment has the above-mentioned structure, and its operation will be explained next.

Now, when the transmission shaft 17 is rotated by the drive of the motor, the rotation of the transmission shaft 17 is transmitted to the arm support shaft 10, and from there to the cleaning tool 16 via the gear transmission mechanism 19. As a result, the cleaning tool 16 rotates in one direction.

Further, since the rotation of the transmission shaft 17 is transmitted to the drive shaft 23, the eccentric pin 26 of the disc 25 attached to the end thereof rotates around the drive shaft 23, and the first
The arm 13 moves up and down along the arm support shaft 10 and the guide rod 12. When the cleaning tool 16 is lowered, the distributor 1 rotates the cleaning tool 16 in one direction.
The cleaning tool 16 is lowered in a timely manner so as to enter the outer end of the divided mass 2.

Further, as the arm support shaft 10 rotates, the cam 28 attached to the upper end moves the deflecting arm 29 in the longitudinal direction, so the second arm 15 rotates about the connecting pin 14, moving the cleaning tool 16 to the distributor. The arm support shaft 10 is moved in the direction of rotation of the arm support shaft 10 by the action of the surface cam 20 attached to the transmission shaft 17.
The rotating frame 11 rotates around the center, and the cleaning tool 16 moves in the radial direction of the distributor 1.

In the embodiment, the cleaning tool 16 moves in the direction of rotation of the circular distributor 1 in the lowered position towards the center of the circular distributor 1, and then rises and moves in the direction of rotation of the circular distributor 1 in the raised position. The cleaning tool 16 is moved in a well-timed manner so as to move in a direction opposite to the direction of the cleaning tool 16 and away from the circular distributor 1.

On the other hand, when the circular dispenser 1 is rotated in the direction of the arrow in FIG. 2, the ends of the opening/closing lids 3 of the divided squares 2 move along the opening/closing guides 6, so that the opening/closing lids 3 are opened.

Therefore, when the circular distributor 1 is rotated, when the transmission shaft 17 is rotated and suction force is applied to the suction hose 7 at the same time, the inner and outer ends of the divided mass 2 held in an open state by the opening/closing guide 6 The cleaning tool 16 descends toward , the lower end hits the upper surface of the open/close lid 3 , and then moves toward the inner end of the divided mass 2 .

Therefore, the deposits on the inner surface of the divided mass 2 and the upper surface of the opening/closing lid 3 are removed by contact with the cleaning tool 16, and the deposits falling downward are sucked by the suction hose 7. When the cleaning tool 16 moves to a position where it comes into contact with the inner end of the divided mass 2, the cleaning tool 16 moves above the divided mass 2, moves toward the outside of the distributor 1 in the raised position, and then It descends again toward the next divided square 2, and sequentially cleans the divided squares 2 that are opened by the opening/closing guide 6.
