Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a device for handling tablets or similar shaped articles, and a posture control feeding device for flat cylindrical articles that is fed from the supply side to the processing side in a stable posture. Regarding

(Prior Art) Conventionally, in providing a drug to a patient based on a prescription, a pharmacy such as a hospital / clinic sometimes divides one drug into further divided doses according to the prescription. In this case, if the tablets were manually divided into tablets one by one, the operation would be hindered, or the tablets could not be divided correctly and could not be crushed and could not be used. In addition, a device that can easily divide a tablet by putting it on a machine has been developed because it becomes impossible to administer a drug by absorbing moisture from the cross section unless the drug is divided immediately before the drug is administered.

In such a device, it is necessary to position the tablets in a flat state and supply them one by one to the cutting operation position of the tablets. Therefore, the posture of the tablets is corrected before being fed one by one from the feeder and supplied to the cutting operation site by the cutter. As a means for allowing the thus-supplied tablets to be sent to a target position in a predetermined posture, a method in which the tablets are fluffed on the upper side of a moving passage (for example, Japanese Patent Laid-Open No. 2-29257). Or a method in which a tablet is tilted by contact on the upper side of a moving passage so that the tablet cannot be delivered unless it collapses and passes through a gap (for example, JP-A-63-192442).
It is known by the publication).

(Problem to be Solved) In the tablet posture control means in the tablet dividing device as described above, for example, according to the brush-like posture control method, the function of the brush portion for control deteriorates during frequent use. However, when the tablet is fed from the feeder, the tablet rolls without being flattened and is fed into the transport mechanism as it is, which is likely to cause inconvenience. Further, the fixed attitude control means has a drawback that when the tablet is caught in the gate portion, the passage is blocked at the portion and the subsequent tablet cannot be delivered. Such a problem occurs not only in the tablet cutting / dividing device but also in a device in which the tablet or the like needs to be moved in a stable state with its flat surface facing upward.

According to the present invention, in order to solve such a problem, when a tablet or an article having a similar shape is flattened and supplied to a target portion, the tablet or the article is intermittently supplied. Posture control device capable of reliably sending out a flat columnar article to be held in a flat state without obstructing the passage by a posture correcting mechanism that rotates up and down and without deteriorating the function even after long-term operation To provide.

(Means for Solving the Problem) In order to achieve the above-mentioned object, a posture control feeding device for a flat cylindrical article according to the present invention sequentially feeds a flat cylindrical article from a supply side to a next process in a stable posture. In the apparatus, a pair of feed rollers including an upper feed roller and a lower feed roller is provided on the lower end side of the first chute having a required inclination angle, and the flat cylindrical article has a thickness between the pair of feed rollers. The lower feed roller is arranged so that a slightly larger gap is formed, and the distance between the gap and the upper surface of the lower end of the first chute is not less than the diameter of the flat columnar article. Second on the downstream side of
Arrange a press roller that can move up and down freely above the chute of
A feed belt is wound between the pressing roller and the upper feed roller, and the driving force is transmitted so that the peripheral speeds of the feed belt and the lower feed roller are synchronized. It is a feature.

(Operation) The device of the present invention is arranged such that if a flat columnar article to be processed is intermittently supplied on the upstream side of a pair of feed rollers arranged so that a required gap is formed between the pair of feed rollers. Since the distance between the gap and the upper surface of the lower end of the first chute is set to be equal to or larger than the diameter of the flat cylindrical article, the flat cylindrical article to be processed must be provided on either peripheral surface (upper side) of both feed rollers. The feed belt is wound around the feed roller), and the movement of the peripheral surface of the feed roller causes the feed roller to be drawn into the gap between the feed rollers and is fed as it is to the downstream side. In particular, the flat cylindrical article rolled on the upper surface of the first chute and fed to the lower feed roller comes into contact with the peripheral surface of the lower feed roller and is always in a recumbent state to be scooped up. The contact area with the peripheral surface of the lower feed roller becomes large, and it is positively guided between the upper and lower feed rollers and fed out in a flat state. Then, on the downstream side of both the feed rollers, the feed belt wound around the upper feed roller is projected, and the vertically movable presser roller is lifted up to pass therethrough. The cylindrical article is arranged in a flat state, slides down the upper surface of the second chute, and is sent to the next step.

(Effect of the Invention) According to the device of the present invention, the flat cylindrical article to be processed can be positively controlled and sent out by the two rotating upper and lower curved surfaces, so that the flat surface faces upward. Even if the object to be processed is like a tablet without damaging the function of the control unit, it will not be damaged for attitude control, and the attitude should be adjusted to a flat state to ensure the next step. Can be sent to.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.
It is as follows.

FIG. 1 and FIG. 2 show a main part of a posture control feeding device 10 used in a tablet dividing machine for dividing a tablet into two pieces. Attitude control sending device 10 is parallel to the required distance 2
A pair of support plates 11 and 11 rotatably supports a pair of upper and lower feed rollers 12 and 13, and a feed belt 14 formed of a flat belt is wound around the upper feed roller 12 as shown in the drawing, The press roller 15 which is freely movable in the vertical direction is provided on the side of the feed belt 14
It is arranged to be wrapped around. The gap B formed between the feed rollers 12 and 13 (strictly, formed by the outer surface of the feed belt 14 wound around the upper feed roller 12 and the peripheral surface of the lower feed roller 13) is flat to handle. The thickness is set to be slightly larger than the thickness of the cylindrical article (specifically, tablet A). The distance between the gap between the feed rollers 12 and 13 and the lower end of the chute upper surface 21, which will be described later, is set to be equal to or greater than the diameter of the flat cylindrical article (tablet A). Reference numerals 16 and 16 'are staples that keep the support plates 11 and 11 at constant intervals. The pressing roller 15 is composed of both support plates 11, 11.
In a free state between them, the feed belt 14 is arranged so that tension acts on the feed belt 14 by its own weight. Alternatively, as another supporting means of the press roller 15, an arc hole drawn with a required radius with respect to the shaft center of the lower feed roller 13 is provided in the support plate, and the shaft end of the press roller 15 is engaged with the arc hole. Then, it may be rotatably supported in a vertically movable state.

The feed rollers 12 and 13 are designed to rotate in the direction of the arrow in FIG. 1 by being given a driving force from the outside through gears 17 and 17 'attached to the ends of the shafts 12' and 13 '. There is. Of course, the feed belt wrapped around the upper feed roller 12
14 also rotates in the same manner.

As shown in FIG. 1, the posture control delivery device 10 thus configured has the upper and lower feed rollers 12, 1 at the upstream portion of the tablet supply chute (second chute) 20 to be handled.
The gap B formed by 3 is assembled and used so as to be located at a position higher than the upper surface of the chute 20. In addition, the upper surface 21 of the chute 20 on the upstream side of the attitude control delivery device 10
It is preferable that the tip be lower than the downstream side.

Specific examples used by being incorporated in the tablet dividing machine are shown in FIGS. 4 and 5.

The above attitude control delivery device 10 is incorporated in the upper part of the box-shaped gas 30 and in the upstream part of the chute 20 which is attached at a front downward slope.

One tablet is intermittently provided on the upper side of the space (18) formed by the upper surface (21) of the chute (first chute) located on the upstream side of the posture control feeding device (10) and the feeding rollers (12, 13). A well-known tablet feeder 60 is provided on the machine body 25 so that A can be delivered, and the tablets A delivered from the tablet feeder 60 are dropped and supplied to the space 18. Power from a drive motor (not shown) of the tablet pinching / conveying mechanism 30 and the cutting mechanism 40 (both of which will be described later) is branched to both the feed rollers 12 and 13, and the ends of the roller shafts 12 'and 13' are separated. It is adapted to be driven via gears 17, 17 '. The space 18 is provided by the tablet feeder 60 described above.
When the tablets A are supplied one by one, the tablets A dropped on the chute upper surface 21 roll on the chute upper surface 21 and come into contact with the peripheral surface of the lower feed roller 13 as shown in FIG. 3A. At this time, if the tablet A comes into contact with the peripheral surface of the feed roller 13 on a flat surface, it is introduced into the gap B between the upper and lower feed rollers 12 and 13 so that it can be scooped up (see FIG. 3b). After A has passed through the gap B, it is kept in a flat state on the chute 20 on the downstream side by the pressing force of the pressing roller 15 on the downstream side acting on the feed belt 14, and is then adjusted in posture. And sent on the chute 20 to the next step.

If the tablet A dropped and supplied to the space 18 is in the upright state and the peripheral surface is in contact with the peripheral surface of the lower feed roller 13, the tablet A contacted by the rotation of the feed roller 13 At the moment when the posture becomes unstable and falls, the posture is adjusted and guided to the gap portion B between the feed rollers 12 and 13 in the above-described manner, and is fed to the downstream side. Further, even when the tablet A falls from the feeder 60 and comes into contact with the upper feed roller 12, if the tablet A falls to both feed rollers 12 and 13, the posture is adjusted and fed by the same procedure as described above. Therefore, the gap B is not blocked by the tablet A.

The tablet A delivered to the chute 20 is a tablet pinching / conveying mechanism 30 constituted by symmetrically arranging endless conveying belts 31 on both sides below the chute 20 extending from the lower end thereof.
Move to department. Then, the tablet A has a conveyor belt 3 which is set in advance so that the tablet A can be clamped according to the diameter of the tablet A.
It is pinched from both sides by 1,31 and conveyed to the cutting position. At the downstream position of the sandwiching and conveying mechanism 30, the processed tablets A are
The cutter 42 descends only when the sheet is sent, and the cutting mechanism 40 is provided between the cutter 42 and the pedestal 44 to cut the tablet A to be processed.
When the tablet A is pinched and conveyed to the cutting position by the cutter supporting arm of the cutting mechanism 40 arranged above the cutting position by the rotary cam 46 driven in association with the driving of the conveyor belt 31. A cutter 42 attached to the lower end of the tip 41 is pushed down via an operation piece 43 controlled by a solenoid 45 attached to the cutter support arm 41, and the conveyor belts 31, 31
The tablet A sandwiched by is divided into two sides. In the figure, reference numeral 32 is a supporting member for the conveyor belt drive section of the conveyor mechanism,
