Description

Syringe test device

[0001] The present invention relates to a syringe inspection device.

[0002] A syringe inspection device is a device that helps workers inspect the inside of a syringe for foreign substances and the appearance of the liquid.

[0003] Through the syringe inspection device, multiple syringes are transported to the inspection area, where the worker can inspect the inside of the syringe to determine whether there are any unsuitable foreign substances and whether there are any abnormalities on the exterior of the syringe, thereby selecting defective products.

[0004] The inspection area can be divided into two inspection stations and a background board can be installed to ensure good identification of foreign substances.

[0005] Additionally, each inspection station is equipped with lighting and a magnifying glass to assist workers in inspecting products.

[0006] The purpose of the present invention is to provide a syringe inspection device that can more clearly determine whether the amount of drug in a syringe is correct or the state of the drug.

[0007] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned herein will be clearly understood by workers from the description below.

[0008] The embodiment is a syringe inspection device having an inlet section, a first transfer section, a first inspection section, a second transfer section, a second inspection section, and a third transfer section arranged in that order along a movement path of a syringe, wherein the inlet section includes a rail that supports a flange of a body of the syringe and supplies the syringe to the first transfer section in an upright state, and the first transfer section includes a first rotation section, a second rotation section, and a third rotation section that are arranged spaced apart from each other, and the first circumference of the first rotation section and the second circumference of the second rotation section are arranged to overlap in a first region, and the second circumference of the second rotation section and the third circumference of the third rotation section are arranged to overlap in a second region, so that the syringe is supplied to the first inspection section through the first region and the second region, and the inlet section includes a plurality of lifting blocks, a conveyor belt connecting the first inspection section and the lifting blocks, and a first opening / closing section arranged in front of the first lifting block arranged at the lowermost end among the plurality of lifting blocks, and the first The opening and closing portion may be arranged to be movable in the vertical direction, so as to block the inlet toward the first lifting block to prevent the syringe from entering the first lifting block, or to open the inlet toward the first lifting block to allow the syringe to enter the first lifting block, thereby providing a syringe inspection device.

[0009] The above-mentioned input section includes a second opening section arranged at the rear of a second lifting block arranged at the uppermost end among the plurality of lifting blocks, and the second opening section is arranged to be movable in the vertical direction, so as to block an inlet toward the conveyor belt to prevent a syringe from entering the conveyor belt or open an inlet toward the conveyor belt to allow a syringe to enter the conveyor belt.

[0010] The second transport unit can pick up the syringe that has been inspected in the first inspection unit and move the syringe to the second inspection unit in an inverted state.

[0011] The first rotating part includes a first driving part, a first rotating plate connected to the first driving part, and a plurality of first holders arranged on the first rotating plate, and one of the plurality of first holders can be aligned to the input area and at the same time, another of the plurality of first holders can be aligned to the first area.

[0012] The second rotating part includes a second driving part, a second rotating plate connected to the second driving part, a plurality of second holders arranged with the second rotating plate, and a third driving part connected to the second rotating plate to move the second rotating plate up and down, and the second holder can be aligned to overlap with the first holder.

[0013] The third rotating part may include a fourth driving part, a third rotating plate connected to the fourth driving part, a plurality of third holders connected to the third rotating plate, and a rotating driving part that rotates the third holder.

[0014] The above rotary drive unit includes a first drive unit and a second drive unit arranged on the third circumference, the first drive unit being arranged at a third point corresponding to the second inspection unit, and the second drive unit being arranged between the second area and the third point.

[0015] The above second transfer unit is a multi-axis arm, and can hold the syringe in the first transfer unit and transfer it to the third transfer unit.

[0016] When a defective signal for the syringe is input from the first inspection unit, the syringe can be picked up by the first transport unit and moved to a defective product discharge area.

[0017] The fourth transfer unit is a multi-axis arm, and when a defective signal for the syringe is input from the second inspection unit, the second transfer unit can grip the syringe and move it to a defective product discharge area.

[0018] According to an embodiment, a worker can directly observe the state of the drug solution inside a syringe with the naked eye, and through a process of inspecting while the syringe is upright and a process of inspecting while the syringe is inverted, it provides an advantageous effect of being able to more clearly determine whether the amount of drug solution in the syringe is correct or the state of the drug solution.

[0019] According to an embodiment, there is an advantage in that the syringes flowing into the lifting block from the inlet are blocked or unblocked at regular intervals to align the syringes in the left-right direction (x) in the lifting block.

[0020] According to an embodiment, there is an advantage in that syringes fed from a lifting block to a conveyor belt are blocked or unblocked at regular intervals so that the syringes can be easily placed on a rail heading to a first transport section.

[0048] Hereinafter, embodiments of the present invention will be described with reference to drawings schematically illustrating embodiments of the present invention. In the drawings, variations in the shapes depicted may be expected, for example, depending on manufacturing techniques and / or tolerances. Therefore, embodiments of the present invention should not be construed as limited to the specific shapes of the regions depicted herein, but should include, for example, variations in shapes resulting from manufacturing processes.

[0049] Fig. 1 is a perspective view illustrating a syringe inspection device according to an embodiment.

[0050] Below, in the drawing, the x-axis represents the left-right direction of the syringe inspection device, the y-axis represents the front-back direction of the syringe inspection device, and the z-axis represents the up-down direction of the syringe inspection device.

[0051] Referring to FIGS. 1 and 2, the syringe inspection device according to the embodiment may include an injection unit (100), a first transfer unit (200), a first inspection unit (300), a second transfer unit (400), a second inspection unit (500), and a third transfer unit (600).

[0052] The syringe to be inspected is moved from right to left in the drawing based on the left-right direction (x). In the drawing, it is positioned in the order of the first inspection section (300) and the second inspection section (500) from right to left.

[0053] The first transfer unit (200) is located between the input unit (100) and the first inspection unit (300). The second transfer unit (400) is located between the first inspection unit (300) and the second inspection unit (500).

[0054] Syringes are sequentially supplied to the first transfer unit (200) through the input unit (100). The first transfer unit (200) transfers the syringes to the first inspection unit (300). In the first inspection unit (300), the inspection is performed with the syringes in an upright state. In the first inspection unit (300), the syringes that have completed the initial inspection are supplied to the second inspection unit (500) through the second transfer unit (400). The syringes supplied to the second inspection unit (500) are inspected in an upright state. The syringes that have completed the inspection through the second inspection unit (500) are supplied to the discharge unit (700) through the third transfer unit (600). In this way, the syringes (10) that have completed two inspections are transferred to the next process through the discharge unit (700).

[0055]

[0056] Figure 2 is a perspective view showing the input section (100).

[0057] Referring to FIG. 2, the input unit (100) is a device that supplies syringes in an upright state to the first transfer unit (200) and the first inspection unit (300). The input unit (100) includes a plurality of lifting blocks (110). The lifting blocks (110) are configured to transport the syringes to a conveyor belt (120). The lifting blocks (110) have a bar shape that is arranged long in the left-right direction (x). The plurality of lifting blocks (110) are arranged in the front-back direction (y) and are sequentially arranged at intervals in the vertical direction (z).

[0058] Syringes are placed on each lifting block (110). At this time, the syringes are laid down in the left-right direction (x) in the same direction as the arrangement of the lifting block (110).

[0059] The lifting blocks (110) rotate in the up-and-down direction (z) by a driving device and transport the syringes (10) to the conveyor belt (120).

[0060] The syringes (10) are moved to the upper lifting block (110) along the up-and-down circular rotation of the lifting block (110) and transported to the uppermost conveyor belt (120 in FIG. 3). Since the syringes (10) are laid down, their stability is higher than when they are standing, so they do not fall off the lifting block (110), thereby increasing the transport efficiency of the syringes (10).

[0061] A conveyor belt (120) is located at the top of the input section (100). The conveyor belt (120) circulates and transfers the syringes (10) received from the lifting block (110) to the rail (150). The syringes (10) on the conveyor belt (120) are transferred to the rail (150) on the conveyor belt (120) while lying horizontally. The rail (150) is connected to the first inspection section (300). The rail (150) guides the syringes to the first inspection section (300) in an upright state.

[0062] The rail (150) is formed with a gap to guide the syringe to be seated on the rail (150) in an upright state.

[0063] When a syringe, which is transported while lying down in the left-right direction (x) in the same direction as the arrangement of the lifting block (110), reaches the rail (150), the body of the syringe containing the liquid is heavier than the plunger of the syringe, so the body of the syringe falls between the gaps of the rail (150). At this time, since the flange part (the part protruding outward from the body) of the syringe body is caught on the rail (150), the plunger part of the syringe is established in a state in which it is exposed to the upper side of the rail (150).

[0064]

[0065] FIG. 3 is a drawing showing an input unit (100) including a first opening unit (130) and a second opening unit (140), FIG. 4 is a drawing showing the operation of the first opening unit (130), and FIG. 5 is a drawing showing the operation of the second opening unit (140).

[0066] Referring to FIGS. 3 to 5, the injection unit (100) may include a first opening / closing unit (130) and a second opening / closing unit (140). The first opening / closing unit (130) is a device that guides the syringes to be aligned in a lying state in the left-right direction (x) rather than in the front-back direction (y) when the syringes are injected into the injection unit (100).

[0067] The first opening / closing unit (130) may include a plate and a driving device for moving the plate. The plate of the first opening / closing unit (130) is shaped like a bar that extends in the left-right direction (x) like the lifting block (110) and is positioned in front of the first lifting block (110A) located at the bottom among the plurality of lifting blocks. The plate of the first opening / closing unit (130) can move in the vertical direction (z).

[0068] First, the first opening (130) blocks the entrance toward the first lifting block (110A) and guides the syringes (S) to be aligned in a lying state in the left-right direction (x) in front of the first lifting block (110A).

[0069] Thereafter, after a certain period of time, the first opening / closing part (130) moves downward to open the inlet (E1) toward the first lifting block (110A). When the first opening / closing part (130) opens the inlet (E1), the syringes (S) that were aligned in a state of being laid down in the left-right direction (x) at the inlet (E1) enter the first lifting block (110A).

[0070] The second opening / closing unit (140) may include a plate and a driving device for moving the plate. The plate of the second opening / closing unit (140) has a long bar shape extending in the left-right direction (x) like the lifting block (110) and is located behind the second lifting block (110B) located at the top among the plurality of lifting blocks. In addition, the plate of the second opening / closing unit (140) is located at the entrance (E2) of the conveyor belt (120). The plate of the second opening / closing unit (140) can move in the vertical direction (z).

[0071] First, the second opening (140) blocks the entrance (E2) toward the conveyor belt (120) and serves to temporarily block the syringes (S) in front of the second lifting block (110B) to prevent too many syringes (S) from entering the conveyor belt (120). If too many syringes (S) enter the conveyor belt (120), the syringes (S) will not be able to settle on the rail (150), so this needs to be prevented.

[0072] While the second opening (140) blocks the syringes (S) facing the conveyor belt (120), after a certain period of time, the second opening (140) moves upward to open the inlet (E2) facing the conveyor belt (120). When the inlet (E2) of the conveyor belt (120) is opened, the syringes (S) blocked by the second opening (140) enter the conveyor belt (120).

[0073]

[0074] FIG. 6 is a drawing showing the first rotation part (210) and the second rotation part (220) of the first transfer part (200), FIG. 7 is a plan view showing a syringe (S) being transferred from the input part (100) to the first rotation part (210) of the first transfer part (200), and FIG. 8 is a side view showing a syringe (S) being transferred from the input part (100) to the first rotation part (210) of the first transfer part (200).

[0075] Referring to FIGS. 6 to 8, the first transfer unit (200) includes a first rotation unit (210). The first rotation unit (210) may include a first driving unit (211), a first rotation plate (212), and a first holder (213).

[0076] The first driving unit (211) is connected to the first rotary plate (212) and rotates the first rotary plate (212). A plurality of first holders (213) may be arranged on the first rotary plate (212). The first rotary plate (212) may be an annular member.

[0077] The first holder (213) may be positioned near the edge of the first rotary plate (212). For example, four first holders (213) may be positioned at equal intervals in the circumferential direction with respect to the center of the first rotary plate (212). When the first rotary plate (212) rotates, the first holders (213) also rotate.

[0078] The first transport unit (200) includes a second rotating unit (220). The second rotating unit (220) may include a second driving unit (221), a second rotating plate (222), a second holder (223), and a third driving unit (224).

[0079] The second driving unit (221) is connected to the second rotary plate (222) and rotates the second rotary plate (222). A plurality of second holders (223) may be arranged on the second rotary plate (222). The second rotary plate (222) may be a square member, but is not limited thereto. The second holders (223) may be arranged at each end of the second rotary plate (222). For example, two second holders (223) may be arranged at each end of the second rotary plate (222).

[0080] The third driving unit (224) is connected to the second rotary plate (222) and can move the second rotary plate (222) in the up-and-down direction (z).

[0081]

[0082] Figure 9 is a plan view showing a state in which the first rotation part (210) of the first transfer part (200) rotates, and Figure 10 is a side view showing a state in which the first rotation part (210) of the first transfer part (200) rotates.

[0083] As illustrated in FIGS. 9 and 10, when the first rotary plate (212) rotates, the first holder (213) located in the injection area (K) rotates and moves out of the injection area (K), and a new first holder (213) without a syringe (S) is aligned to the injection area (K). Then, the first holder (213) to which another syringe (S) is fixed is aligned to the first area (P1).

[0084] The second turntable (222) may be positioned above the first turntable (212). Another syringe (S) may be fixed to the second holder (223) of the second turntable (222), and the second holder (223) aligned to the first area (P1) is empty.

[0085]

[0086] Fig. 11 is a drawing showing the third rotation part (230) of the first transfer part (200), and Fig. 12 is a plan view showing the first transfer part (200).

[0087] Referring to FIGS. 11 and 12, the third rotating part (230) is positioned behind the first inspection part (300). The third rotating part (230) may include a fourth driving part (231), a third rotating plate (232), a third holder (233), and a rotating driving part (234).

[0088] The fourth driving unit (231) is connected to the third rotating plate (232) and rotates the third rotating plate (232). A plurality of third holders (233) may be arranged on the third rotating plate (232). The third rotating plate (232) may be an annular member, but is not limited thereto.

[0089] The third holder (233) may be positioned near the edge of the third rotating plate (232). For example, four third holders (233) may be positioned at equal intervals in the circumferential direction with respect to the center of the third rotating plate (232). When the third rotating plate (232) rotates, the third holders (233) also rotate.

[0090] Meanwhile, the third holder (233) can be arranged to be rotatably positioned with respect to the third rotary plate (232). The direction of the rotation axis of the third holder (233) can be parallel to the direction of the rotation axis of the third rotary plate (232), and the third holder (233) can be rotated by the rotation drive unit (234). Accordingly, the third rotary plate (232) also rotates with respect to the central axis of the third rotary plate (232), and the third holder (233) rotates by the rotation drive unit (234).

[0091] The first circumference (O1) of the first rotating part (210) and the second circumference (O2) of the second rotating part (220) are arranged to overlap in the first region (P1). In addition, the second circumference (O2) of the second rotating part (220) and the third circumference (O3) of the third rotating part (230) are arranged to overlap in the second region (P2).

[0092] Meanwhile, the rotary drive unit (234) may include a first drive unit (234a) and a second drive unit (234b).

[0093] The first driving unit (234a) and the second driving unit (234b) are each disposed on the third circumference (O3). That is, the rotary driving unit (234) rotates the third holder (233) with the first driving unit (234a) and the second driving unit (234b) being disposed on the third rotary plate (232).

[0094] The second drive unit (234b) is aligned with the first inspection unit (300).

[0095] The first driving unit (234a) rotates the syringe (S) faster than the rotation speed of the second driving unit (234b) before the syringe (S) is aligned to the first inspection section (300). This is to increase the accuracy of the inspection of the syringe (S) by suspending foreign substances contained in the liquid solution of the syringe (S). The first driving unit (234a) is connected to the third holder (233), and when the first driving unit (234a) rotates, the third holder (233) also rotates. When the third holder (233) rotates, the syringe (S) fixed to the third holder (233) rotates, so that foreign substances contained in the liquid solution inside float, making it easier to observe.

[0096] The second driving unit (234b) rotates the syringe (S) at a lower speed than the rotation speed of the first driving unit (234a) while the syringe (S) is aligned to the first inspection section (300). The second driving unit (234b) rotates at a relatively lower speed than the first driving unit (234a) to slowly rotate the syringe (S) aligned to the first inspection section (300). This is to ensure the ease of inspection of the syringe (S) by the operator with the naked eye.

[0097] The second driving unit (234b) is connected to the third holder (233) located behind the first inspection unit (300), and when the second driving unit (234b) rotates, the third holder (233) also rotates. When the third holder (233) rotates, the syringe (S) fixed to the third holder (233) rotates.

[0098] In the first region (P1), with the syringe (S2) aligned, the second rotary plate (222) waits. At this time, the second holder (223) of the second rotary plate (222) holds and fixes the syringe (S3). In the second region (P2), the syringe (S4) fixed to the third holder (233) is aligned (Fig. 12).

[0099]

[0100] Figure 13 is a drawing showing a state in which a syringe (S0) is supplied to an injection unit (100), and Figure 14 is a drawing showing a state in which a third rotation unit (230) rotates.

[0101] Fig. 13 illustrates a state in which a syringe (S0) is supplied to a first holder (213) located in an injection area (K) through a rail (150). The first rotary plate (212) rotates, and the syringe (S1) located in the injection area (K) moves 90 degrees to a lower position of the first rotary plate (212) based on Fig. 13, and the syringe (S2) located in the lower position moves to the first area (P1).

[0102] Referring to FIGS. 12, 13, and 14, when the first rotary plate (212) of the first rotary part (210) rotates and the syringe (S2) is aligned in the first area (P1), the third rotary part (230) rotates and the empty third holder (233) is positioned in the second area (P2). (FIG. 14) The syringe (S4) in the second area (P2) moves toward the first driving unit (234a) and is aligned by the first driving unit (234a) and rotates at high speed. The second rotary plate (222) waits while fixing the syringe (S3) (FIG. 14).

[0103]

[0104] FIG. 15 is a plan view illustrating a process in which a syringe (S) of a first rotating part (210) is transported to a third rotating part (230) through a second rotating part (220), and FIG. 16 is a side view illustrating a process in which a syringe (S) of a first rotating part (210) is transported to a third rotating part (230) through a second rotating part (220).

[0105] Referring to FIGS. 14, 15 and 16, a syringe (S2) is aligned in the first region (P1), and an empty third holder (233) is aligned in the second region (FIG. 14). At this time, a syringe (S3) is fixed to the second holder (223) positioned on one side of the second rotary plate (222), and the second holder (223) positioned on the other side of the second rotary plate (222) is empty (FIG. 14).

[0106] Then, the second rotary plate (222) of the second rotary part (220) rotates (Fig. 15). As the second rotary plate (222) rotates, the second holder (223) on one side that is empty is aligned to the first area (P1), and the second holder (223) on the opposite side where the syringe (S3) is fixed is aligned to the second area (P2) (Fig. 15). Thereafter, the second rotary plate (222) moves downward by the third driving part (224) (Fig. 16). When the second rotary plate (222) moves downward, in the first area (P1), the empty second holder (223) grips the syringe (S2) fixed to the first holder (213). And the syringe (S3) fixed to the second holder (223) is fixed to the empty third holder (233).

[0107] And a syringe (S0) can be supplied through a rail (150) to the injection area (K) and fixed to an empty first holder (213).

[0109] Figure 17 is a side view showing a state in which the second rotating plate (222) moves upward.

[0110] Referring to Fig. 17, thereafter, when the second rotary plate (222) rises, the syringe (S2) that was in the first holder (213) in the first area (P1) rises together while being fixed to the second holder (223). Then, at the second point (P2), the syringe (S3) that was in the second holder (223) is transported to the third holder (233) and fixed to the third holder (233), and the second holder (223) rises in an empty state.

[0111] Figure 18 is a plan view showing the rotation of the third rotary plate (232) after the upward movement of the second rotary plate (222).

[0112] Referring to Fig. 18, the second rotary plate (222) moves upward and then rotates to maintain a standby state. Then, the second holder (223) that was holding the syringe (S2) above the first region (P1) rotates and moves toward the second region (P2).

[0113] And a new first holder (213) is positioned in the first area (P1) and a new syringe (S1) is positioned in the first area (P1).

[0114] As the third turntable (232) rotates, the syringe (S3) in the third holder (233) of the second area (P2) is aligned to the position of the first driving unit (234a), and an empty third holder (233) is positioned in the second area (P2).

[0116] Figure 19 is a drawing illustrating the first inspection unit (300) and the second inspection unit (500).

[0117] Referring to FIGS. 18 and 19, the syringe (S4) aligned in the first inspection unit (300) rotates at a low speed. The first inspection unit (300) may be equipped with a transparent lens (not shown) placed between the worker and the syringe of the first transfer unit (200) and a first background plate (not shown) placed behind the syringe (S). By magnifying the syringes (S4) through the first inspection unit (300), the worker can easily visually check the capacity or condition of the drug solution contained inside the syringe (S4) and the presence of floating substances.

[0118] The first background plate (not shown) of the first inspection section (300) provides a background and / or light to the inspection area so that the operator can easily visually check the volume or condition of the drug contained within the syringe (S4). The volume or condition of the drug contained within the syringe (S) can be easily checked by light from the light inserted within the first inspection section (300).

[0119] At this time, the first background plate of the first inspection unit (300) may be a white background plate for detecting black-colored foreign substances. In addition, the second background plate (not shown) of the second inspection unit (500) described later may be a black background plate for detecting white-colored foreign substances. In addition, the colors of the first background plate of the first inspection unit (300) and the second background plate of the second inspection unit (500) may be interchanged.

[0120] In the first inspection section (300), the syringe (S4) is in an upright position. At this time, the upright position means a state in which the body of the syringe (S4) containing the drug solution is positioned at the bottom and the plunger of the syringe (S) is positioned at the top.

[0121]

[0122] Figure 20 is a drawing showing the operating state after the inspection is completed in the first inspection unit (300).

[0123] Referring to Fig. 20, a syringe (S4) that has completed inspection in the first inspection section (300) moves to the third area (P3). A new syringe (S3) is aligned in the first inspection section (300). A second transfer section (400) is located in the third area (P3). The second transfer section (400) may be a multi-axis arm.

[0124] Figure 21 is a drawing illustrating a process of discharging a defective syringe (S4).

[0125] Referring to Fig. 21, a button may be provided near the first inspection section (300). If a worker discovers a defective syringe (S4) in the inspection area, the worker may press the button. When the user presses the button and a defective signal is generated, the second transport section (400) picks up the syringe (S4) determined to be defective in the third area (P3) and transports it to the defective product discharge area (T) for discharge.

[0126] FIG. 22 is a drawing illustrating a process of transporting a syringe (S) from a first inspection unit (300) to a second inspection unit (500), and FIGS. 23 and 24 are drawings illustrating a process of transporting a syringe (S) from a second transfer unit (400) to a third transfer unit (600).

[0127] Referring to Fig. 22, if no defects are found in the syringe (S) in the first inspection unit (300), the syringe (S4) of the first inspection unit (300) is transported to the second inspection unit (500). The second transport unit (400) grips the syringe (S) in the third area (P3) and transports the syringe (S4) to the fourth area (P4) of the third transport unit (600). The configuration of the third transport unit (600) is the same as that of the third rotation unit (230).

[0128] The second inspection unit (500) is configured to include a transparent lens, so as to magnify the syringes (S) that have entered the inspection area, so that the operator can easily visually check the amount or state of the drug contained inside the syringes (S). The second background plate (not shown) of the second inspection unit (500) also provides a background and / or light to the inspection area so that the operator can easily visually check the amount or state of the drug contained inside the syringes (S). The second background plate (not shown) of the second inspection unit (500) may be a black background plate that detects white-colored foreign substances. The first background plate (not shown) of the first inspection unit (300) is exemplified as a white background plate that detects black-colored foreign substances, and the second background plate (not shown) of the second inspection unit (500) is exemplified as a black background plate that detects white-colored foreign substances. The present invention is not limited thereto, and the first background plate of the first inspection unit (300) may be a black background plate for detecting white-colored foreign substances, and the second background plate of the second inspection unit (500) may be a white background plate for detecting black-colored foreign substances.

[0129] The syringe (S) is mounted in an inverted state in the empty holder of the third transfer unit (600) by the second transfer unit (400). At this time, the inverted state means a state in which the body of the syringe (S) containing the liquid is positioned at the top and the plunger of the syringe (S) is positioned at the bottom.

[0130] If the second inspection unit (500) determines that the syringe is defective and the worker presses the button in the second inspection unit (500), the fourth transfer unit (800) in the form of a multi-axis arm can pick up the syringe (S) from the third transfer unit (600) and discharge it to the defective product discharge area (T). Syringes (S) that are not found to be defective in the second inspection unit (500) can be discharged to the discharge unit (700) through the fourth transfer unit (800). Here, the fourth transfer unit (800) may be a multi-axis arm.

[0131] Referring to FIGS. 23 and 24, the second transfer unit (400) is implemented in the form of a multi-axis robot arm to directly grip the syringe (S4) of the third rotary plate (232) of the first transfer unit (200) and transfer it to the third transfer unit (600). At this time, the second transfer unit (400) switches the syringe (S4) from an upright state to an inverted state and transfers it to the third transfer unit (600). At this time, the inverted state means a state in which the body of the syringe (S) containing the liquid solution is positioned at the upper side and the plunger of the syringe (S) is positioned at the lower side. Through the second transfer unit (400) in the form of a multi-axis arm, there is an advantage in that the syringe (S4) is naturally switched from an upright state to an inverted state during the process of being transferred from the third rotary plate (232) of the first transfer unit (200) to the third transfer unit (600).

[0132] Above, specific embodiments of the syringe inspection device of the present invention have been described, but it is obvious that various modifications are possible within the scope of the present invention.
