Description

Additive injection device for pharmaceutical containers

[0001] The present invention relates to an additive dosing device for a pharmaceutical container. More specifically, the present invention relates to an additive dosing device for a pharmaceutical container that can minimize feeding errors in additives during the feeding process and simplify the overall structure and control method.

[0002] Pharmaceuticals manufactured by pharmaceutical companies are diverse, and are supplied to users in various dosage forms, each tailored to their intended use or intended use. In particular, considering ease of use and ease of mass production, most pharmaceuticals are manufactured as tablets (or "pills") or capsules. After counting the dosage, they are typically packaged in pharmaceutical containers and supplied to users.

[0003] To distribute pharmaceuticals in packaged form, a pharmaceutical packaging device has been developed that places the pharmaceuticals in pharmaceutical containers and packages them. This device automates the entire pharmaceutical packaging process, including container washing, drug loading, antioxidant application, and capping.

[0004] These pharmaceutical packaging devices are configured to perform various processes, such as a container supply process for supplying pharmaceutical containers, a cleaning process for air-cleaning the inside of the pharmaceutical containers, a process for adding additives such as antioxidants to the inside of the pharmaceutical containers to prevent denaturation of the pharmaceuticals, a process for quantitatively counting pharmaceuticals and adding them to the pharmaceutical containers, and a process for fastening the caps on the pharmaceutical containers. Each process is performed in an automated manner by separately manufactured individual process devices.

[0005] The individual process devices used in these pharmaceutical packaging processes are manufactured in various forms depending on the circumstances of each pharmaceutical company. Among these individual process devices, the devices that inject additives such as antioxidants into the pharmaceutical container are manufactured in a wide variety of ways depending on the type of pharmaceutical container and the type of additive.

[0006] The additive injection device of such a pharmaceutical container generally includes an additive supply unit that supplies the additive, a discharge unit that discharges the additive toward the pharmaceutical container so that the additive is injected into the pharmaceutical container, and a feeding unit that continuously transports the additive supplied through the additive supply unit and feeds it to the discharge unit.

[0007] The configuration of the feeding section that feeds the additive to the discharge section is a very important configuration that can ensure the stability of the entire additive injection process. However, conventional additive injection devices often fail to continuously and smoothly feed the additive during the additive feeding process, resulting in feeding errors. In particular, even when normal feeding is not performed and a feeding error occurs, the operating state of the feeding section is maintained, resulting in frequent problems such as additives overflowing to the outside, contamination, making it impossible to use, or causing the device to malfunction.

[0008] [Prior Art Literature]

[0009] [Patent Document]

[0010] (Patent Document 1) Korean Patent No. 10-1946895

[0011] The present invention was invented to solve the problems of the prior art, and the purpose of the present invention is to provide an additive injection device for a pharmaceutical container that can sequentially align and feed a plurality of additives along a circular feeding path without a separate alignment means, minimize feeding errors for additives during the feeding process, and simplify the overall structure and control method.

[0012] Another object of the present invention is to provide an additive injection device for a pharmaceutical container that can prevent contamination or damage to the additive by allowing the additive to move normally even when an abnormal feeding state such as an over-feeding state occurs, and can maintain a more stable operating state by allowing normal feeding operation to be performed again after a certain period of time when the abnormal feeding state is resolved without stopping the feeding device.

[0013] The present invention provides an additive injection device for a pharmaceutical container, which injects an additive into a pharmaceutical container in a pharmaceutical packaging process of inserting a pharmaceutical into a pharmaceutical container and packaging the pharmaceutical, the device comprising: a base frame formed so that a pharmaceutical container is seated on an upper surface; a supply module arranged on the upper part of the base frame to supply an additive; a feeding module that aligns and transports the additive supplied from the supply module along a circular feeding path and sequentially feeds the additive through a feeding duct connected to one side of the feeding path; a discharge module that receives the additives sequentially fed from the feeding module and discharges them one by one so that they are injected into a pharmaceutical container; and a control unit that controls the operation of the supply module, the feeding module, and the discharge module.

[0014] In addition, the additive injection device of the pharmaceutical container further includes a feeding detection means for detecting a feeding state of the additive by the feeding module; and a feeding blocking means mounted on the feeding module and operating to block the additive from flowing into the feeding duct from the feeding path, and the control unit can receive a detection signal from the feeding detection means and control the operation of the feeding blocking means according to the received detection signal.

[0015] At this time, the feeding module includes an outer rotating ring formed in a hollow cylindrical shape with an upper surface forming the feeding path and rotating around a vertical axis; an outer rotating driving unit that rotates the outer rotating ring; an inner rotating plate formed in a circular shape with one surface such that the outer peripheral surface contacts or is arranged close to the inner peripheral surface of the outer rotating ring and is arranged on a plane perpendicular to the vertical axis and an inclined axis, and rotates around the inclined axis; an inner rotating driving unit that rotates the inner rotating plate; and an upper guide body that is arranged on the upper portion of the outer rotating ring to guide the additive while surrounding the external space of the feeding path, and to which the feeding duct is coupled on one side, wherein the additive supplied by the supply module can move to the upper surface of the outer rotating ring while rotating together with the inner rotating plate on the upper surface of the inner rotating plate and be introduced into the feeding duct along the feeding path.

[0016] Additionally, an inlet guide portion may be formed on one side of the upper guide body to guide the additive on the feeding path to flow into the feeding duct.

[0017] In addition, the upper surface of the inner rotating plate is formed to be inclined downward from the inclined axis toward the outer end, and a point located at the uppermost end of the circumferential outer end can be arranged to have the same height as the upper surface of the outer rotating ring.

[0018] Additionally, the upper surface of the inner rotating plate may be arranged so that an area adjacent to the inclined axis is positioned higher than the upper surface of the outer rotating ring.

[0019] Additionally, the feeding duct may be arranged in a tangential direction of the feeding path so that the additive is introduced into the feeding duct during the process of being transported along the feeding path, and may be arranged to be inclined downward toward the discharge module.

[0020] Additionally, the feeding detection means may be configured to detect the inflow status of the additive flowing into the feeding duct.

[0021] In addition, the feeding blocking means may be mounted on the upper guide body so as to be positioned forward from the inlet of the feeding duct and configured to switch the feeding path for the additive, and the additive may be configured to move from the feeding path to the inner rotating plate as the feeding blocking means operates.

[0022] In addition, the feeding blocking means includes a blocking body having one end rotatably coupled to the upper guide body about a vertical hinge axis so as to protrude in a direction blocking the feeding path from the upper guide body or to be introduced in a direction opening the feeding path; and an actuator that rotates the blocking body about the vertical hinge axis, wherein the blocking body may be formed such that an inner protruding surface guides the additive from the feeding path to the inner rotary plate while protruding and rotating from the upper guide body.

[0023] According to the present invention, a plurality of additives can be sequentially aligned and fed along a circular feeding path without a separate alignment means through a vertically arranged outer rotating ring and an inclined inner rotating plate, thereby minimizing feeding errors for additives and simplifying the overall structure and control method because a separate alignment means is unnecessary.

[0024] In addition, by providing a means to detect an abnormal feeding state, block the inflow of feeding, and circulate the additive, even if an abnormal feeding state such as an over-concentrated feeding state occurs, the additive can move normally, thereby preventing contamination or damage to the additive, and when the abnormal feeding state is resolved after a certain period of time without stopping the feeding device, normal feeding operation can be performed again, thereby maintaining the stable operation state of the entire device.

[0033] An additive injection device for a pharmaceutical container according to one embodiment of the present invention is a device for injecting an additive (20) such as an antioxidant into a pharmaceutical container (10) in a pharmaceutical packaging process of inserting a pharmaceutical into a pharmaceutical container (10) and packaging the pharmaceutical, and is configured to include a base frame (100), a supply module (200), a feeding module (300), and a discharge module (400).

[0034] Here, the additive (20) may be an antioxidant that is added to prevent the denaturation of the pharmaceutical product added to the pharmaceutical container (10), and in addition, another product other than the pharmaceutical product that can be added to the pharmaceutical container (10) may be added. In this case, the additive (20) refers to a solid product, not a liquid product.

[0035] The base frame (100) is a configuration that supports the entire device and is configured in a form in which a plurality of frames and plates, etc. are combined. A container fixing portion (110) capable of fixing a pharmaceutical container (10) is formed on the upper surface of the base frame (100). Two container fixing portions (110) may be formed so that two pharmaceutical containers (10) can be fixed at the same time. The container fixing portion (110) is configured so that the pharmaceutical container (10) is continuously and repeatedly supplied through a separate container supply device (not shown) as the addition of an additive (20) to the pharmaceutical container (10) is completed.

[0036] The supply module (200) is configured to be arranged on the upper part of the base frame (100) and to supply additives (20), and includes a storage case (210) in the form of an upper open container capable of storing a plurality of additives (20) supplied by workers or the like, as illustrated in FIG. 1, and a supply duct (220) formed on one side of the storage case (210) so as to supply a plurality of additives (20) to the feeding module (300). Although not illustrated, a supply device (not illustrated) may be provided inside the storage case (210) to supply some of the additives (20) stored in the storage case (210) to the feeding module (300) through the supply duct (220), and such a supply device may be configured to operate automatically at a set interval or at a set time interval by a user's operation according to a set cycle. The supply device may be configured in a form in which a supply plate (not shown) that can push the additive (20) into the supply duct (220) moves up and down, and may also be applied in various forms that can push the additive (20) into the supply duct (220).

[0037] The feeding module (300) transports the additive (20) supplied from the supply module (200) by aligning it along a circular feeding path (301), and sequentially feeds the additive (20) through a feeding duct (310) connected to one side of the feeding path (301).

[0038] The dispensing module (400) receives additives (20) sequentially fed from the feeding module (300) and dispenses them one by one so that they are injected into the pharmaceutical container (10). The dispensing module (400) is connected to the feeding duct (310) to receive the additives (20), and has a dispensing port (410) formed at the bottom through which the additives (20) can be dispensed one by one. The dispensing port (410) can be arranged vertically above each container fixing portion (110) so that the additives (20) are injected into the pharmaceutical containers (10) fixed to the two container fixing portions (110). Inside the discharge module (400), a transfer passage (not shown) is formed that can transfer the additive (20) received from the feeding duct (310) to the discharge port (410) by its own weight. One end of the transfer passage is connected to the feeding duct (310), and the middle section can be formed to branch into two and be connected to two discharge ports (410), respectively. A distributor (not shown) that can distribute the additive (20) to the two discharge ports (410) can be provided in the branch section of the transfer passage, and a discharge operation plate (not shown) that operates to discharge the additive (20) one by one in response to the supply speed of the pharmaceutical container (10) can be mounted on the two discharge ports (410). The discharge operation plate can be configured to keep the discharge port (410) closed and move to open the discharge port (410) only when it is desired to discharge the additive (20). The discharge operating plate may be configured to slide by a separate discharge driving unit (not shown).

[0039] These supply modules (200), feeding modules (300) and discharge modules (400) can be controlled through separate control units (not shown), and in particular, the discharge module (400) must be controlled in conjunction with the supply speed of the pharmaceutical container (10) so that the additive (20) can be normally injected into the pharmaceutical container (10).

[0040] Meanwhile, the additive injection device according to one embodiment of the present invention may further include a feeding detection means (320) that detects the feeding state of the additive (20) by the feeding module (300), and a feeding blocking means (330) that is mounted on the feeding module (300) and operates to block the additive (20) from flowing into the feeding duct (310) from the feeding path (301), and a detailed description thereof will be described later with reference to FIG. 6.

[0041] According to this structure, a plurality of additives (20) supplied to the feeding module (300) through the supply module (200) are transported in an aligned state along a circular feeding path (301) through the feeding module (300), introduced into the feeding duct (310), and delivered from the feeding duct (310) to the discharge module (400) to be discharged one by one to be injected into the pharmaceutical container (10).

[0042] Looking at the configuration of the feeding module (300) in more detail, the feeding module (300) includes an outer rotating ring (340) formed in a hollow cylindrical shape so that the upper surface forms a feeding path (301) and rotates around a vertical axis (C1), an outer rotating drive unit (350) that rotates the outer rotating ring (340), an inner rotating plate (360) that is formed in a circular shape on one side so that the outer peripheral surface contacts or is arranged close to the inner peripheral surface of the outer rotating ring (340) and is arranged on a plane perpendicular to the vertical axis (C1) and an inclined axis (C2) that rotates around the inclined axis (C2), an inner rotating drive unit (370) that rotates the inner rotating plate (360), and an upper guide body (380) that is arranged on the upper part of the outer rotating ring (340) to surround the outer space of the feeding path (301) and guide the additive (20) and has a feeding duct (310) coupled to one side. It is composed of.

[0043] The outer rotation ring (340) is formed in a hollow cylindrical shape so that the upper surface forms a feeding path (301), and a support plate (341) for supporting the outer rotation ring (340) is coupled to the lower part to rotate together with the outer rotation ring (340). The center of the support plate (341) is formed in an open shape so that the inclined axis (C2) of the inner rotation plate (360) passes through it. The outer rotation drive unit (350) includes a drive motor (351) and a power transmission means (352) for transmitting the rotational force of the drive motor (351) to the support plate (341) and the outer rotation ring (340), and the power transmission means (352) may be configured in a form in which a gear connected to the motor shaft of the drive motor (351) and a gear connected to the lower part of the support plate (341) are meshed with each other. Of course, it can be changed into various other forms.

[0044] As illustrated in FIG. 5, the inner rotating plate (360) is arranged on a perpendicular plane of an inclined axis (C2) inclined with respect to a vertical axis (C1) in the shape of a disk on the lower surface, and rotates around the inclined axis (C2), and the upper surface is formed to have an inclined surface in the form of a shape that slopes downward as it goes outward from the central region adjacent to the inclined axis (C2). A central shaft (361) parallel to the inclined axis (C2) is penetrated and connected to the central part of the inner rotating plate (360), and an internal rotating drive unit (370) is coupled to the central shaft (361) to rotate and drive the central shaft (361). The internal rotating drive unit (370) may include a driving motor (371) and a motor rotating shaft (372) that rotates by the driving motor (371). The motor rotating shaft (372) is arranged parallel to the inclined axis (C2) and has one end coupled to the central shaft (361). Accordingly, when the driving motor (371) rotates, the motor rotation axis (372) and the center shaft (361) rotate around the inclined axis (C2), and together with this, the internal rotation plate (360) rotates around the inclined axis (C2).

[0045] According to this structure, the outer rotating ring (340) has a horizontal upper surface and rotates around a vertical axis (C1), and the inner rotating plate (360) is arranged to be inclined inside the outer rotating ring (340) and rotates around an inclined axis (C2). At this time, the inner rotating plate (360) is arranged so that the point located at the uppermost end of the circumference of the outer end is at the same height as the upper surface of the outer rotating ring (340), as illustrated in FIG. 5. In addition, the upper surface of the inner rotating plate (360) is formed to be inclined downward from the central region toward the outer end, and the central region of the upper surface of the inner rotating plate (360) adjacent to the inclined axis (C2) is arranged to be higher than the upper surface of the outer rotating ring (340).

[0046] The upper guide body (380) may be formed in a shape having a circular through hole formed in the center with a roughly flat plate shape, and the inner circumference of the through hole surrounds the outer space of the feeding path (301) formed in the outer rotating ring (340) to guide the additive (20). A feeding duct (310) is coupled to one side of the upper guide body (380), and the additive (20) moving along the feeding path (301) is introduced into the feeding duct (310). An inlet guide portion (381) may be formed on one side of the upper guide body (380) to guide the additive (20) on the feeding path (301) to be introduced into the feeding duct (310), and the additive (20) can be introduced into the feeding duct (310) more smoothly by the inlet guide portion (381). At this time, the feeding duct (310) is arranged in the tangential direction of the feeding path (301) as shown in FIG. 4 so that the additive (20) is smoothly introduced into the feeding duct (310) during the process of being transported along the feeding path (301), and is arranged to be inclined downward toward the discharge module (400) so that the introduced additive (20) is transferred to the discharge module (400) by its own weight.

[0047] According to this structure, the upper surface of the outer rotating ring (340) of the feeding module (300) forms a circular feeding path (301), and a plurality of additives (20) supplied from the supply module (200) are transported along the feeding path (301) and introduced into the feeding duct (310).

[0048] Looking at it in more detail, the additive (20) supplied through the supply duct (220) of the supply module (200) is supplied to the upper surface of the inner rotary plate (360) of the feeding module (300). The additives (20) located on the upper surface of the inner rotary plate (360) rotate together with the inner rotary plate (360) as shown in FIG. 4, and during the rotation process, they move to the outer end by centrifugal force, etc., and move from the outer end to the upper surface of the outer rotary ring (340), and thereafter, they rotate together with the outer rotary ring (340) on the upper surface of the outer rotary ring (340) and move along the feeding path (301) and are introduced into the feeding duct (310). As shown in Fig. 5, the inner rotating plate (360) is arranged to be inclined and rotates around the inclined axis (C2), and the upper surface of the inner rotating plate (360) is inclined downward from the central region toward the outer end, so that the additive (20) located on the inner rotating plate (360) moves to the outer end not only by centrifugal force but also by its own weight during the rotation process.

[0049] In addition, since the point located at the uppermost end of the outer circumference of the inner rotating plate (360) is arranged to be at the same height as the upper surface of the outer rotating ring (340), the additive (20) that rotates together with the inner rotating plate (360) moves to the upper surface of the outer rotating ring (340) at the point where the upper surface of the inner rotating plate (360) and the upper surface of the outer rotating ring (340) are at the same height. That is, the additive (20) rotates together with the inner rotating plate (360) and sequentially moves to the upper surface of the outer rotating ring (340) at the point where the upper surface of the inner rotating plate (360) and the upper surface of the outer rotating ring (340) are at the same height. If the additive (20) that has not moved to the upper surface of the outer rotating ring (340) at that point rotates together with the inner rotating plate (360) once again and arrives at that point again to move to the upper surface of the outer rotating ring (340). Of course, if it fails to move to the upper surface of the outer rotating ring (340) again, it rotates repeatedly together with the inner rotating plate (360). That is, the additives (20) located on the inner rotating plate (360) rotate repeatedly together with the inner rotating plate (360) and sequentially move to the upper surface of the outer rotating ring (340) one by one as they arrive at the corresponding point.

[0050] According to this structure, the additive (20) sequentially moves from the inner rotating plate (360) to the upper surface of the outer rotating ring (340), then rotates together with the outer rotating ring (340) and moves along the feeding path (301), and then flows into the feeding duct (310) arranged on the feeding path (301).

[0051] Accordingly, the feeding module (300) according to one embodiment of the present invention can sequentially align a plurality of additives (20) along a circular feeding path (301) without a separate alignment means, and can minimize feeding errors of the additives (20) during the feeding process by transporting them in this aligned state and allowing them to flow into the feeding duct (310). In addition, since a separate additive alignment means is unnecessary, the structure and control method can be simplified.

[0052] Meanwhile, as described above, the additive injection device according to one embodiment of the present invention is equipped with a feeding detection means (320) and a feeding blocking means (330). The configuration thereof will be examined below with reference to FIG. 6.

[0053] Figure 6 is an operating state diagram schematically illustrating the operating state of a feeding blocking means according to one embodiment of the present invention.

[0054] The feeding detection means (320) detects the feeding status of the additive (20) by the feeding module (300), and the feeding blocking means (330) is mounted on the feeding module (300) and operates to block the additive (20) from flowing into the feeding duct (310) from the feeding path (301). The control unit receives a detection signal from the feeding detection means (320) and controls the operation of the feeding blocking means (330) so that it operates according to the received detection signal.

[0055] More specifically, the feeding detection means (320) is formed to detect the inflow status of the additive (20) flowing into the feeding duct (310). For example, it may be provided with an inlet detection sensor (321) that is positioned on the upper portion of the internal rotating plate (360) adjacent to the feeding duct (310) to detect the inflow status of the additive (20) flowing into the feeding duct (310), and a duct detection sensor (322) that is mounted on one side of the feeding duct (310) to detect how much of the additive (20) has flowed into the internal space of the feeding duct (310) or whether it is moving normally. The inlet detection sensor (321) and the duct detection sensor (322) may be applied as an optical sensor that can detect the presence or absence of the additive (20) using light, and various other types of sensors may also be applied.

[0056] In the case of the inlet detection sensor (321), it can be configured to detect the amount of additive (20) that has not been introduced into the feeding duct (310) near the inlet (311) of the feeding duct (310). If the additive (20) introduction state into the feeding duct (310) is overcrowded, the additive (20) can no longer be introduced into the feeding duct (310) and remains outside the inlet (311) of the feeding duct (310), so if this is detected, it is possible to determine whether the current feeding state is normal. Similarly, the duct detection sensor (322) can determine an error or overcrowding state of the feeding state by detecting whether the additive (20) is moving normally in the internal space of the feeding duct (310).

[0057] In this way, when the feeding state is determined to be overcrowded through the feeding detection means (320), the control unit controls the operation of the feeding blocking means (330).

[0058] The feeding blocking means (330) is mounted on the upper guide body (380) so as to be positioned forward from the inlet (311) of the feeding duct (310) and operates to switch the feeding path for the additive (20). When the feeding blocking means (330) operates, the additive (20) can be configured to move from the feeding path (301) to the internal rotary plate (360). In this way, when the additive (20) moves from the feeding path (301) to the internal rotary plate (360) by the operation of the feeding blocking means (330), the additive (20) repeatedly rotates together with the internal rotary plate (360) and then moves back to the feeding path (301), and then circulates back to the internal rotary plate (360) by the feeding blocking means (330). That is, the inflow of the additive (20) into the feeding duct (310) is blocked until the blocking operation of the feeding blocking means (330) is released, and in this state, the additive (20) is repeatedly rotated together with the internal rotating plate (360).

[0059] According to this structure, even if an abnormal feeding condition such as an over-fed condition occurs, the additive (20) can rotate together with the internal rotating plate (360) and move normally, so that the additive (20) can be prevented from overflowing to the outside and becoming contaminated or damaged, and when the over-fed condition is resolved after a certain period of time without stopping the feeding device, the blocking operation of the feeding blocking means (330) can be released so that normal feeding operation can be performed again.

[0060] The feeding blocking means (330) may be configured to include a blocking body (331) that is rotatably connected to the upper guide body (380) about a vertical hinge axis (332) so that one end thereof protrudes from the upper guide body (380) in a direction that blocks the feeding path (301) or is introduced in a direction that opens the feeding path (301), and an actuator (333) that rotates the blocking body (331) about the vertical hinge axis (332).

[0061] At this time, the blocking body (331) may be formed to have an inclined surface in an inclined direction with respect to the feeding path (301) so that the inner protruding surface (334) guides the additive (20) from the feeding path (301) to the inner rotating plate (360) while protruding and rotating from the upper guide body (380). More specifically, the inclined surface may be formed in a shape having a concave curve so as to more smoothly switch the movement path of the additive (20).

[0062] Figure 6 (a) shows a state in which the feeding blocking means (330) is not operating, and Figure 6 (b) shows a state in which the feeding blocking means (330) is operating. When the feeding blocking means (330) operates, the additive (20) moves from the feeding path (301) to the inner rotating plate (360) near the inlet (311) of the feeding duct (310) by the inner protrusion (334) of the blocking body (331).
