The purpose is to provide compatibility.

It is necessary to automate medication administration to store a specified number of tablets of a specified drug type in the same package from among various types of tablets with different specifications. In addition, tablet feeding machines (similar to sorting machines) that conform to the specifications of the target tablets are arranged, each tablet is stored in these machines, and the necessary tablet feeding machines are activated when dispensing the tablets. It is necessary to release and feed a predetermined number of tablets of each type to the packaging mechanism.

However, this tablet feeding machine is compact and accommodates a large number of tablets in a relatively narrow case, so it is inconvenient to replenish tablets within the case, and it is not compatible with changes in tablet types. This is something that could not have happened.

This invention prevents the above-mentioned drawbacks by making the cup part that accommodates the tablets removable and interchangeable.

Alternatively, a plurality of shock absorbing seats 16 made of anti-vibration rubber are installed directly by cutting out the necessary portion of the shelf board 3, and a motor 12 is further attached to this, and the motor shaft 121 is inserted into the center hole. 112.

As the motor 12, a type that can control the rotation angle, such as a pulse motor, is used.

A shaft joint 13 is provided at the shaft end of the motor shaft 121, and one or more magnet pieces 14 of permanent magnets are attached to appropriate positions of the fitting portion 111.

This shaft joint 13 and its related parts will be described later for convenience.

A ring-shaped charger base 40 made of an insulating material is attached to the peripheral wall of the tablet drop hole 113, and a rechargeable light emitter 41 made of a microbulb and a rechargeable light receiver 42 made of a phototransistor are opposed to the photoelectric terminal seat 40. It is installed and constitutes a photoelectric type fall counter 4.

The cup part 2 includes a cup body 21 that fits into the force pump holder 11, a transmission system consisting of a transmission shaft 22 and a shaft coupling 23, a control system for the tablet O such as an alignment board 24, a partition plate 25, and other accessories. Consists of mechanisms.

The cup body 21 is roughly divided into a bottom part 211 and a cylindrical hopper part 215 connected to the top part. 2121 is carved into the fitting part 212, and the bottom part 211 has a center hole 213 and a tablet drop hole 21.
4 is the center hole 112 of the cup holder 11 and the tablet drop hole 11
It is drilled corresponding to 3.

A magnet piece 26 made of permanent magnets with polar directions opposite to each other and attracted to each other is attached to the loose fitting part 212 at a position corresponding to the magnet piece 14 to prevent the fitting with the base part 1. It is a mustard fastening that is secure and does not interfere with attachment and detachment.

The hopper part 215 has a cylindrical inner chamber in which the alignment board 24 and the transmission shaft 22 as its drive system are housed.
A shaft coupling 23 is coupled to the shaft end of the transmission shaft 22 on the center hole 213 side.

As shown in FIG. 2, the alignment plate 24 includes a cylinder 240 into which the transmission shaft 22 is fitted, a conical top surface 241 consisting of a stepped inclined surface provided on the top surface, and a conical top surface 241 that protrudes radially around the entire circumference of the bottom. A large number of alignment holes 243 passing through the projecting pieces 242 in the vertical direction are arranged at equal intervals by the projecting pieces 242.

The alignment hole 243 has a hole diameter that allows the tablets O to be used to pass through one at a time, and that does not allow a plurality of tablets O to collide with each other and obstruct passage, that is, the hole diameter is such that the tablets O do not clog. Select.

As the transmission shaft 22 rotates, the alignment plate 24 also rotates, and the tablets O accommodated in the hopper part 215 are agitated by the step of the conical top surface 241.
The tablet O introduced into the gap between the cylinder body 240, that is, the annular cavity 29, enters the alignment hole 243, and enters the tablet drop hole 214 due to the rotation of the transmission shaft 22.
14, 113, and 32 to the outside of the container, are counted by the falling number counter 4, slide down along the drug guide plate 5, and are collected into a packaging mechanism (not shown).

The motor shaft 121 and the transmission shaft 22 are connected by a shaft coupling 13.23 provided at each shaft end.

It is necessary that the shaft couplings 13, 23 be connected by simple pressing and immediately separated by pulling out, and that reliable rotational transmission be achieved.

For this purpose, a friction coupling mechanism, a clutch coupling mechanism, or a dog coupling mechanism can be used, although in the illustrated embodiment a spline coupling mechanism is used.

That is, a floating hole 1211 is formed in the motor shaft 121, into which a spline shaft type shaft joint 13 is loosely fitted, and is loosely fitted so that it can be raised and lowered by a retaining pin 131 inserted through the floating hole 1211. Shaft coupling 13 and motor 12

Therefore, according to the illustrated mechanism, when the cup part 2 is pulled upward, the shaft joint 13 is easily separated from the shaft joint 23, and when the cup part 2 is placed on the cup holder 11, the center of the shaft is As soon as the splines match even if the shaft joint 13 is pressed down for a while, and even if they do not match, as soon as the splines start rotating, the motor shaft 121 moves upward into the shaft joint 23 to ensure a secure connection. The rotation is faithfully transmitted to the transmission shaft 22 and alignment plate 24.

A partition plate 25 that advances and retreats into the hopper part 215 to open and close the passage to the tablet drop hole 214 is inserted into the cup body 21 at a position directly above the tablet drop hole 214, and is inserted into the cup body 21 at a position directly above the alignment hole 243. This is pushed in to ensure that the tablets O enter the tablet drop hole 214 only from the side in sequence and fall one by one, and to prevent the tablets O from accidentally falling when being carried. It is a large number of tablets.
This is pulled out and used only in special cases, such as when objects are allowed to fall continuously.

In the figure, 27 is a handle provided for carrying the cup portion 2, and 28 is a lid that covers the hopper portion 215.

Care must be taken to prevent misuse by attaching markings for each standard of the tablet O, such as coloring and letters, to appropriate places on the cup portion 2.

The preparation platform 1 is mounted in multiple rows on shelves 3 in the case of a medication dispensing machine, and is provided with a common drug guide plate 5, as well as a common wiring duct 6, where all motors Control wiring is provided at 12 and connected to the control mechanism.

In the above interchangeable tablet feeding machine, when the cup part 2 is placed on the table part 1 and the groove 2121 and the center rod 1111 are aligned, the fitting parts 111, 212 are located at a position where the tablet drop holes 113, 214 are aligned with each other. are fitted into each other and the shaft coupling 12.23
are connected to each other, and the cup portion 2 is held in this fitted state by the magnetic attraction force of the magnet pieces 14 and 26.

Then, when the motor 12 is driven, the alignment plate 24 is rotated in one direction, and the tablets O accommodated in the hopper part 215 are stirred by the step of the conical top surface 241 while moving between the hopper part 215 and the cylinder body 240. The tablet is introduced into the gap between the tablets and the annular cavity 29, enters the alignment hole 243, is conveyed in the circumferential direction by the protruding piece 242, and enters the tablet drop hole 214.
