Description

Individual tablet feeding device {TABLET FEEDER}

The present invention relates to an individual tablet feeding device, and more particularly, to an individual tablet feeding device capable of accurately classifying individual tablets and supplying them to a packaging machine regardless of the shape of the tablet.

In general, tablet-type drugs (circle, hereinafter collectively referred to as tablets) are manufactured as pills or capsules, and are usually counted in a quantity and put into various packaging materials (for example, stick-type containers, medicine bottles, etc.) and then packaged. It is shipped through the process.

These tablets, such as tablets, are counted and injected quantitatively, but are quantitatively injected into various facilities through an automated tablet individual supply device for speed and workability.

Specifically, the conventional tablet individual supply device causes the tablets supplied through the hopper to be transported with vibration through a tray connected with the vibration means, and the tablets falling downward from the end of the tray are counted through a count detection sensor. It is a configuration in which quantitative injection is made.

However, according to the conventional tablet individual supply device, not only it takes a lot of time to count the tablets, there is a high risk of a quantitative supply error due to a malfunction of the sensor, and the counting means and the vibration means for transferring the tablets according to the operation of the facility. Since the operation of the lamp must be temporarily stopped, there is a problem in that the continuity of the quantitative supply is deteriorated.

In addition, conventionally, there is a problem that the vibration of the vibrating means linked to the tray is not well transmitted to the tray, so that the transfer of tablets for counting is not performed smoothly, and the tablets conveyed from the end of the tray are splashed due to a drop shock due to vibration. There is a problem in that it is not put into the correct position, and it is difficult to control the tablet to be supplied quantitatively to the correct position when the facility is operated at high speed.

As a prior art for solving the above problems, there are registered patent No. 10-0759726, published patent No. 10-2004-0078000, etc.

Next, the discharge block 20 is fixed and installed at the lower part of the hopper, communicates with the tablet discharge port 21 at the lower end, to the upper side of the discharge port 21, and is installed to a predetermined height of the storage unit 11 It has a pipe (22).

Specifically, the discharge port 21 is a hole formed to have a predetermined length up and down, and part or all of the discharge pipe 22 is fitted and coupled to the discharge port 21, wherein the discharge pipe 22 has an upper end having a predetermined length or more It is installed so as to protrude upward from the upper surface of the discharge block 20.

At this time, there is no limit to the number of discharge ports 21 and discharge pipes 22, but it is preferable that a plurality of discharge ports 21 and discharge pipes 22 are provided at predetermined intervals in the left and right length direction of the discharge block 20. .

In addition, an identification groove 23 is provided at the front and/or rear of the discharge block 20 to enable internal identification of the discharge port 21,

At both sides of the discharge port 21, a guide hole 24 through which the guide rod 33 of the input block 30 is inserted and slidably coupled is provided through vertically.

In addition, the discharge block 20 includes an opening/closing plate 25 for opening and closing the discharge port 21 to discharge individual tablets T.

The opening/closing plate 25 opens and closes the lower opening of the discharge port 21, and the front and rear moving blocks 26 and 27 penetrate the front and rear surfaces of the discharge block 20 and are connected to both ends of the guide bar 28. The opening and closing plate 25 is coupled and connected from the lower surface of the rear moving block 27 toward the front, and the opening and closing plate 25 passes through the discharge port 21 according to the forward and backward movement of the moving blocks 27 through a cylinder or the like. Open and close.

Of course, the specific structure or method for the opening and closing operation of the opening and closing plate 25 in the present invention may be different.

For example, a method in which the discharge hole 21 is opened and closed through the left and right movement of the opening and closing plate by providing a discharge hole in the opening and closing plate corresponding to the left and right length of the discharge block 20,

Alternatively, a method of opening/closing the discharge port 21 through one direction rotation of the opening/closing plate by providing a plurality of discharge holes along the circumferential direction may be considered.

Subsequently, the input block 30 is installed to elevate and descend from the storage unit 11, and includes a slide hole 31 through which the discharge pipe 22 is inserted, and when the descent is completed, the discharge pipe 22 The upper end of the slide hole 31 protrudes upward, and when the ascending is completed, the upper end of the discharge pipe 22 is accommodated in the slide hole 31, so that one of the tablets of the storage unit 11 when ascending and descending Into the discharge pipe 22.

Specifically, the slide hole 31 has a hole shape formed through vertically to be shorter than the length of the discharge pipe 22 protruding upward of the discharge block 20, and the discharge pipe 22 is formed on the inner circumferential surface of the slide hole 31. ) Can be added to reduce the friction with the bushing.

This slide hole 31 is formed in a circular shape whose diameter corresponds to the individual size (outer diameter or length, etc.) of the tablet T, so that only one tablet can be inserted into the slide hole 31 do.

In addition, the input block 30 is composed of a guide inclined surface 32 formed so that the upper surfaces of both sides of the slide hole 31 are inclined downward toward the slide hole 31.

This input block 30 seals the lower opening of the storage unit 11 so that the tablets of the storage unit 11 are stored on the storage unit 11,

Therefore, in the state where the input block 30 descends and the discharge pipe 22 protrudes above the slide hole 31, some of the tablets (T) are directly put into the discharge pipe 22 individually and fall to the discharge port 21. And, the remaining part of the tablets (T) remain in the storage unit 11 in a state that cannot be put into the discharge pipe (22).

And when the input block 30 is raised so that the discharge pipe 22 is accommodated in the slide hole 31, the input block 30 pushes up the tablets that could not be added, and at this time, both sides of the slide hole 31 One of the tablets T slides by its own weight by the guide inclined surface 32 provided in the inclined surface 32 and falls into the discharge pipe 22 and then falls to the discharge port 21.

When the raising and lowering of the input block 30 is repeated, the tablets of the storage unit 11 are put into the discharge pipe 22 one by one each time the input block 30 is raised, and the tablets of the storage unit 11 are separately Without the need for alignment, the tablets T are individually stacked and stacked on the discharge pipe 22 and the discharge port 21 individually.

In this state, when the opening and closing plate 25 is repeatedly moved back and forth according to the operation speed of the packaging machine P, the tablets arranged in a row on the discharge pipe 22 and the discharge port 21 open the opening and closing plate 25 Each time it is operated, it is dropped and discharged one by one and supplied to the packaging machine (P).

Therefore, it is possible to quantitatively count and supply individual tablets through operation counting of the opening/closing plate 25 without adding a separate sensor.

Meanwhile, the lifting means 40 for raising and lowering the input block 30 can be implemented by operating a cylinder, etc.

In the present invention, as the lifting means 40, so that the lifting and descending of the input block 30 is smoothly and continuously performed without intermediate stop so that the individual input of the tablet T can be repeated at the same interval,

The driving cam 42 rotated by the motor 41,

Including a driven shaft 43 whose one end is hinged to one surface of the input block 30 and the other end is hinged to a position biased toward one side from the center of the driving cam 42,

When the drive cam 42 is rotated, the input block 30 is elevated and lowered by elevating the driven shaft 43.

Specifically, in the motor 41 installed at the rear (or front) of the hopper 10, the rotation shaft 41a is coupled to the center of the driving cam 42, so that the driving cam 42 is at a constant speed when the motor 41 is operated. It rotates in one direction.

In addition, the driven shaft 43 is rotatably coupled from the rear of the input block 30 through a first rotation shaft 43a provided at one end (upper end) through the guide groove 13 back and forth, and the other end The second rotation shaft 42a provided at the (bottom) can be rotated in a displaced position biased toward one side from the front center of the driving cam 42 so that it is not arranged on the same line with the rotation shaft 41a of the motor 41 Are combined.

Therefore, when the driving cam 42 rotates in one direction by the motor 41, the second rotation shaft 42a rotates together around the rotation shaft 41a and the vertical height is displaced,

According to the height displacement of the second rotation shaft 42a, both ends of the driven shaft 43 rotate left and right around the first and second rotation shafts 43a, 42a, and the entire driven shaft 43 ascends and descends. Thus, the lifting and lowering of the input block 30 is repeatedly performed at the same speed.

In the present invention of this configuration, even if the tablets (T) are not in a complete spherical shape, individual tablets (T) can be classified one by one from the tablets stored in a large amount and supplied to the packaging machine (P) in sequence, and the elevating and descending of the input block 30 It is possible to improve the continuity, accuracy, and operational stability of the quantitative supply of tablets (T) through discharging after aligning the tablets in a row.

In the above description of the present invention, the device for supplying individual tablets has been mainly described with reference to the accompanying drawings, but the present invention can be variously modified, changed, and substituted by those skilled in the art, and such modifications, changes and substitutions are the scope of the present invention.
