Description

Technology Field

[0001] The present invention relates to a linear alignment device and method for a drug supply feeder, wherein the feeder comprises a combination of a rotating disk, a middle drum having a storage surface having a certain height around its circumference when the rotating disk is positioned at an inner diameter and having a support surface along the circumference of its upper portion, and an outer drum having a friction surface located on the outer side of the middle drum and extending to the support surface, wherein the rotating disk, the middle drum, and the outer drum are installed to rotate relative to each other to align drugs. Background Technology

[0002] Generally, pharmaceuticals widely used for the diagnosis, treatment, and prevention of diseases include pills made by compressing powdered or crystalline medicinal materials into a specific shape, and capsules filled with powder, granules, liquid, suspension, or mucus to prevent the medicine from deteriorating and to make it easier to take.

[0003] In particular, pills and capsules are not only preferred by patients because they have accurate dosages and are very convenient for taking, carrying, and storing, but pharmaceutical companies are also mass-producing them due to these advantages.

[0004] Since pharmaceuticals such as pills and capsules are mass-produced through automated processes, rather than defects caused by ingredients or dosage, the exterior is partially damaged due to the discharge process, for example, contact or impact between pills or capsules, and as a result, many defective products are produced.

[0005] Therefore, a tablet sorter was installed at the final stage of the pharmaceutical production process to inspect for external damage to the tablets through the inspector's visual inspection and sensing means (not shown).

[0006] In relation to such technology, the technology of a purification supply device is disclosed in the prior art patent No. 1216534 by the applicant of the present invention, and its configuration, as shown in FIG. 1, includes a rotating plate (110) that is inclined and rotates as a power transmission part, a linear transfer plate (150) that is inclined downward toward the outer diameter side in the circumferential direction and rotates as a power transmission part while maintaining the same horizontal plane as the top dead center of the rotating plate (110), and a fixing block (170) installed to be detachably attached to the outer diameter side of the linear transfer plate (150).

[0007] And, the above-mentioned linear transfer plate (150) is formed with an inclined surface (151) and a horizontal surface (155) and is installed to have the same number of rotations and direction of rotation as the rotating plate, thereby facilitating the movement of tablets (T) fed by centrifugal force, and allowing the tablets (T) to be placed along the circumference by the inclined surface (151) so as to be stably moved in a linear fashion.

[0008] However, the above-mentioned tablet supply device has the disadvantage that it is difficult to accurately align drugs with various shapes, making it difficult to supply the drugs accurately, and that the drugs are damaged by impact from falling when the alignment is abnormal, and that the efficiency of the next process, the inspection process, is reduced due to inaccurate supply. The problem to be solved

[0009] The objective of the present invention, which aims to improve upon the aforementioned conventional problems, is to provide a linear alignment device and method for a drug supply feeder that enables rapid supply by accurately aligning the drug in the circumferential direction regardless of the drug formulation, prevents damage to the drug caused by impact from falling, prevents a decrease in inspection efficiency caused by inaccurate tablet supply, and enables automatic alignment by adjusting a constant rotational speed according to the drug formulation. means of solving the problem

[0010] To achieve the above objective, the present invention provides a feeder

[0011] rotating disk

[0013] It is composed of a combination of outer drums having a friction surface extending from the outer side of the intermediate drum and a support surface, and

[0014] The above-mentioned rotating disk, intermediate drum, and outer drum are installed to rotate relative to each other, thereby providing a linear alignment device for a drug supply feeder.

[0015] In addition, a linear alignment device for a drug supply feeder is provided, wherein a pad having a positioning groove corresponding to the supplied drug is detachably connected to the periphery of the edge of the inner disk.

[0016] Additionally, a cover frame is further mounted on the upper part of the feeder, which is supported by a frame and on which a camera, etc. is mounted, and the cover frame has a fixed jaw integrally protruding therefrom having a spacing adjustment surface that maintains a horizontal state with respect to the support surface, thereby providing a linear alignment device for a drug supply feeder.

[0017] In addition, the above-mentioned outer drum is replaced by a rotating block connected to a cover frame fixed to the frame so as to be rotatable, thereby providing a linear alignment device for a drug supply feeder.

[0018] Furthermore, the above-mentioned rotating disk, intermediate drum, and outer drum are installed to rotate individually through different motors, and a linear alignment device for a drug supply feeder is provided in which the rotational speed is individually controlled by a signal from a camera mounted on a cover frame and a control unit connected to the camera.

[0019] Meanwhile, the present invention is installed such that the rotating disk, the intermediate drum, and the outer drum are each separated and can rotate relative to each other, and

[0020] The side of the drug placed on the upper support surface of the middle drum is supported by the friction surface of the outer drum by the centrifugal force of the rotating disk, and

[0024] Hereinafter, embodiments of the present invention will be described in detail based on the attached drawings.

[0025] As illustrated in FIGS. 2 to 9, the feeder (100) for supplying purified liquid according to the present invention is composed of a combination of a rotating disk (110), an intermediate drum (130), and an outer drum (150).

[0026] At this time, the rotating disk (110), the intermediate drum (130), and the outer drum (150) are installed to rotate individually through their respective power transmission units (500).

[0027] In addition, the power transmission unit (500) comprises a combination of a motor that supplies power, a gear or shaft coupling provided on a rotating disk, an intermediate drum, and an outer drum to transmit power through the motor, and a bearing provided to allow free rotation.

[0028] Additionally, the rotation disk (110) is installed so that its rotation center axis (111) is positioned at an angle to the frame (300) to rotate at an angle.

[0029] And, the above intermediate drum (130) is formed in a U-shape having a support surface (133) that slopes downward along the upper circumference, while having an arc-shaped storage surface (131) that has a certain height around the circumference when a rotating disk (110) is located inside.

[0030] Furthermore, the outer drum (150) is supported on the upper or outer side of the middle drum (130), and a friction surface (151) of a certain height extending to the support surface (133) is integrally formed.

[0031] At this time, the continuously extending support surface and friction surface are installed to have an overall L-shape.

[0033] Meanwhile, a pad (120) having a positioning groove (121) corresponding to the supplied medicine may be attached to the periphery of the above-mentioned rotating disk (110) so as to be detachable.

[0034] Additionally, a cover frame (500) on which a camera, etc. is mounted while being supported by a frame (300) may be further mounted on the upper part of the feeder (100).

[0035] At this time, the camera (C) is installed to photograph the state of the supplied medicine, and the captured image is supplied to a control unit in which a program is pre-stored to individually control the rotational speeds of each motor that rotates the rotating disk (110), the intermediate drum (130), and the outer drum (150) according to the state in which the medicine is placed, and the rotational speeds of the rotating disk (110), the intermediate drum (130), and the outer drum (150) are controlled by the processing signal of the control unit.

[0036] Additionally, the outer drum (150) may be replaced with a configuration in which it is not installed individually but is installed to rotate freely on a rotating block (570) provided on one side of the cover frame.

[0037] At this time, the outer drum (150) is installed to rotate through a power transmission unit on the cover frame as shown in FIG. 9.

[0038] Additionally, the above cover frame (500) may further protrude a fixing jaw (540) having a spacing adjustment surface (541) that maintains a horizontal state with respect to the support surface.

[0040] On the other hand, the present invention is configured such that the rotating disk (110), the intermediate drum (130), and the outer drum (150) are each installed separately to enable individual operation, and are installed to enable relative rotation of each other by means of a power transmission unit separately provided for each.

[0041] And, the above-mentioned rotating disk (110) is positioned at an angle so that the medicine is aligned and is placed on the support surface (133) of the intermediate drum (130) at the same height as the maximum point by centrifugal force, and its side is supported by the friction surface (151) of the outer drum (150) which is located in the vertical direction and is the side of the support surface (133).

[0042] At this time, the shape of the drug introduced into the intermediate drum is captured by a camera (C), and the rotation speeds of the intermediate drum and the outer drum are individually controlled by a rotation signal from a control unit connected thereto.

[0043] In addition, the above-mentioned drug is aligned by rotating the drug in the forward or reverse direction as shown in FIG. 4a and 4b through relative rotational motion of the middle drum and the outer drum as described above.

[0045] The operation of the present invention, configured as described above, is explained.

[0046] As shown in FIGS. 2 to 9, the feeder (100) of the present invention is composed of a combination of a rotating disk (110), an intermediate drum (130), and an outer drum (150), and the rotating disk (110), the intermediate drum (130), and the outer drum (150) are installed to rotate individually through their respective power transmission units (500) to enable relative rotation, thereby controlling the direction of the drug when it is injected by adjusting the rotational force, and is installed to move in a straight line in the forward direction.

[0047] That is, as shown in FIG. 4a, if the medicine being fed into the intermediate drum (130) is abnormally fed while rotated counterclockwise by the centrifugal force of the rotating disk (110), the rotation speed of the outer drum (150) is increased faster than the rotation speed of the intermediate drum (130) to rotate the medicine clockwise so that the medicine is supported and transported normally.

[0048] In addition, as shown in FIG. 4b, if the medicine being fed into the intermediate drum (130) is abnormally fed while rotated clockwise by the centrifugal force of the rotating disk (110), the rotation speed of the intermediate drum (130) is increased faster than the rotation speed of the outer drum (150) to rotate the medicine counterclockwise so that the medicine is supported and transported normally.

[0049] And, when the above-mentioned drug is aligned by the state rotation of the intermediate drum (130) and the outer drum (150), the frame (300) itself supporting the intermediate drum (130) and the outer drum (150) is also supported by the casing (900) and is supported through a vibration unit (980) or a fine height adjustment unit (970) so that vibration can be applied or the inclination can be adjusted, thereby enabling rapid alignment.

[0050] At this time, the fine height adjustment unit (970) is composed of a vibration motor, and the fine height adjustment unit (970) is composed of a solenoid, etc., and is configured to adjust only the left and right angles around the center.

[0051] In addition, the rotating disk (110), the intermediate drum (130), and the outer drum (150) are each rotated individually through a different power transmission unit (500), and the power transmission unit (500) is composed of a combination of a motor that supplies power, a gear or shaft coupling provided on the rotating disk, the intermediate drum, and the outer drum to transmit power through the motor, and a bearing provided to allow free rotation, thereby enabling adjustment of the desired rotational speed.

[0052] At this time, the state of the chemical supplied to the intermediate drum as described above is captured through a camera, and a program for individually controlling the rotational speed of each motor according to the state of the chemical supplied as described above is installed to be stored in the control unit in advance so that the rotational speed is individually controlled according to the state of the chemical.

[0053] And, the camera is mounted on a cover frame (500) that is positioned on the upper part of the feeder (100) and supported by a frame (300).

[0054] In addition, the rotating disk (110) is installed so that its rotational center axis (111) is positioned at an angle to the frame (300) to rotate, so that the chemical supplied to the bottom dead center is fed into the intermediate drum when it is at the top dead center.

[0055] And, the intermediate drum (130) is formed in a U-shape having a support surface (133) that slopes downward along the upper circumference while having an arc-shaped storage surface (131) that has a certain height around the circumference when a rotating disk (110) is positioned inside, and the outer drum (150) corresponding to the intermediate drum is formed in an L-shape having a friction surface (151) of a certain height that is integrally formed and extends to the support surface (133) and is supported on the upper or outer side of the intermediate drum (130), so as to rotate and move in alignment while supporting the medicine.

[0056] Meanwhile, a pad (120) having a positioning groove (121) corresponding to the supplied medicine may be detachably connected to the periphery of the above-mentioned rotating disk (110) so as to ensure that the state in which the medicine is placed is constant, thereby enabling accurate injection.

[0058] Meanwhile, the outer drum (150) can be replaced with a configuration in which it is not individually installed on the outer side of the middle drum but is integrally provided in a rotating block (570) installed on one side of the cover frame, and the same effect can be achieved, and the outer drum provided in the rotating block (570) is also rotated through a power transmission unit separately provided in the cover frame.

[0059] In addition, the above cover frame (500) has a fixing jaw (540) that protrudes further, having a spacing adjustment surface (541) that maintains a horizontal state with the support surface, so that the injected medicine is accurately supported and prevents it from falling during movement.
