Description

Technical Field

[0001] This utility model belongs to the technical field of injectable drug packaging equipment, specifically relating to an automatic cartoning device for small-volume injectable drugs. Background Technology

[0002] On packaging production lines for small-volume injectables (such as ampoules and vials), each injectable needs to be individually filled into a plastic inner tray, and then the inner tray is placed into an outer paper packaging box. Currently, the process of individually filling the inner tray with injectables is mostly done manually, resulting in low efficiency and high labor intensity. While some existing automated equipment can automate the filling process, its complex structure and high cost make it undesirable. Therefore, there is an urgent need for a simple, automated cartoning device for small-volume injectables that can individually fill the inner tray with small-volume injectables, reducing labor intensity and improving production efficiency. Utility Model Content

[0003] This invention addresses the shortcomings of the prior art by providing a simple automatic boxing device for small-volume injections, which can pack small-volume injections one by one into the inner tray, reducing labor intensity and improving production efficiency.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: An automatic cartoning device for small-volume injections includes a conveying mechanism for conveying inner trays, a dispensing mechanism located above the conveying mechanism, and a controller. The dispensing mechanism includes a storage box for storing injections and a rotating dispensing assembly for separating injections one by one. The rotating dispensing assembly includes a housing, a dispensing roller horizontally rotatably connected within the housing, and a dispensing motor for driving the dispensing roller to rotate. The outer circumferential surface of the dispensing roller has multiple accommodating slots evenly distributed circumferentially to accommodate individual injections. The upper and lower sides of the housing are respectively provided with an inlet and an outlet. The inlet is connected to the dispensing port located at the bottom of the storage box. The conveying mechanism is also provided with a detection sensor for detecting whether the inner tray has reached the dispensing position of the dispensing mechanism. The detection sensor, the conveying mechanism, and the dispensing mechanism are all electrically connected to the controller.

[0005] Preferably, the detection sensor includes an infrared transmitter and an infrared receiver disposed opposite to each other on both sides of the conveying mechanism.

[0006] Preferably, a support frame is provided above the conveying mechanism, the unloading mechanism is provided on the support frame, and the support frame is provided with a discharge hole that matches the discharge port.

[0007] Preferably, the support frame is provided with a guide cylinder connected to the material drop hole at its lower part.

[0008] Preferably, the storage box has an internal accommodating cavity, and the lower part of the accommodating cavity has a funnel-shaped structure that gradually narrows from top to bottom.

[0009] Preferably, the front sidewall of the storage box is a detachable movable plate, and the two sides of the movable plate are provided with backward-bent portions, which are connected to the sidewall of the storage box by screws.

[0010] Preferably, the housing includes a fixed part and a movable part, one end of the dispensing roller is rotatably connected to the movable part, and the other end is rotatably connected to the fixed part.

[0011] Preferably, the storage box and the housing are connected by screws or bolts.

[0012] Preferably, the conveying mechanism includes a frame, a conveyor belt rotatably connected to the frame, and a conveyor motor for driving the conveyor belt.

[0013] Preferably, the surface of the conveyor belt is provided with a positioning groove that matches the inner tray.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes the rotation of a distributing roller to sequentially distribute the injections from the storage box into uniformly spaced grooves on its outer surface. With the assistance of a detection sensor, a conveyor belt propels the inner tray forward at a uniform speed, synchronized with the rotation of the distributing roller. This allows the injections to sequentially fall from the grooves through the discharge holes and guide cylinder into the slots of the inner tray, achieving automatic positioning of the inner tray and automatic continuous dispensing of the injections. This replaces traditional manual operation, improving production efficiency and reducing labor intensity. Furthermore, this invention features a simple structure with few parts, making it easy to manufacture, install, and maintain, thus reducing equipment manufacturing and subsequent maintenance costs.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] like Figure 1 As shown, an automatic cartoning device for small-volume injections includes a conveying mechanism for conveying inner trays, a feeding mechanism located above the conveying mechanism, and a controller 1. The conveying mechanism includes a frame 10, a conveyor belt 11 rotatably connected to the frame, and a conveying motor 12 for driving the conveyor belt. The surface of the conveyor belt is provided with positioning grooves 13 that match the inner trays 14 to prevent the inner trays from shifting on the conveyor belt and to ensure the stability and accuracy of the cartoning operation.

[0021] The feeding mechanism includes a storage box 2 for storing injections and a rotary dispensing assembly for separating the injections one by one. The rotary dispensing assembly includes a housing 3, a dispensing roller 4 horizontally rotatably connected inside the housing, and a dispensing motor 5 for driving the dispensing roller. Multiple receiving slots 401 for accommodating individual injections are evenly distributed circumferentially on the outer circumferential surface of the dispensing roller. The distance between any two adjacent receiving slots is less than the outer diameter of the injection. The housing has an inlet 301 and an outlet 302 on its upper and lower sides, respectively. The inlet is connected to the outlet 201 located at the bottom of the storage box. The storage box and the housing are assembled using screws or bolts. Figures 2 to 5 As shown, in this embodiment, the storage box and the shell are connected by bolts.

[0022] The housing includes a fixed part 303 and a movable part 304 for easy disassembly and maintenance. The two ends of the dispensing roller are rotatably connected to the movable and fixed parts respectively via bearings. The fixed part, movable part, and support frame are all assembled and connected using screws or bolts. The gap between the dispensing roller and the housing is smaller than the outer diameter of the injection to prevent material jamming. The conveying mechanism is also equipped with a detection sensor to check whether the inner tray has reached the dispensing position of the dispensing mechanism. The detection sensor includes an infrared transmitter 6 and an infrared receiver 7 positioned opposite each other on both sides of the conveying mechanism. The detection sensor, conveying mechanism, and dispensing mechanism are all electrically connected to the controller. A support frame 8 is located above the conveying mechanism, combined with… Figure 7 As shown, the feeding mechanism is mounted on a support frame, which has a discharge hole 801 that matches the discharge port. Below the support frame, there is a guide cylinder 9 that is connected to the discharge hole.

[0023] The injectable solutions to be packaged are stacked in a storage box with an open top. The injectable solutions enter the uppermost receiving slot through the discharge port at the bottom and the inlet at the top of the casing. As the dispensing motor drives the dispensing roller to rotate slowly, the injectable solutions sequentially enter the receiving slots around the dispensing roller. The conveying mechanism transports the inner tray. When it reaches the support frame (the dispensing position of the dispensing mechanism), the detection sensor sends a signal to the controller (PLC controller), which controls the dispensing motor to drive the dispensing roller to rotate a fixed angle. In this embodiment, the dispensing roller has 8 receiving slots. Each rotation is 45°. The receiving slot containing the injectable solutions rotates to the discharge port. The injectable solutions fall into the inner tray after passing through the discharge hole and the guide cylinder, thus realizing the dispensing, dispensing, and dropping of the injectable solutions.

[0024] like Figure 6As shown, the storage box has an internal receiving cavity 202. The lower part of the receiving cavity has a funnel-shaped structure that gradually narrows from top to bottom, facilitating the sequential entry of the injection into the discharge port under the action of gravity. The front side wall of the storage box is a detachable movable plate 203. The two sides of the movable plate have backward-bent bending parts 204. The bending parts are connected to the side wall 205 of the storage box by screws, which facilitates both disassembly and assembly, as well as the filling of the injection into the storage box.

[0025] The working process of this utility model is as follows: S1, the dispensing motor 5 drives the dispensing roller 4 to rotate, and the uppermost empty receiving groove 401 will rotate to the position aligned with the discharge port 201 of the storage box 2. At this time, the bottommost injection 15 of the storage box 2 falls into the receiving groove 401 under the action of gravity. As the dispensing roller 4 continues to rotate, the receiving groove 401 carrying the injection gradually turns downward. S2, the conveyor motor 12 drives the conveyor belt 11 carrying the inner tray 14 to move to the side of the feeding mechanism. When the inner tray 14 moves to the preset position below the feeding mechanism, the detection sensor installed on the frame 10 sends a signal to the controller 1. S3. After receiving the signal, the controller 1 sends a command to the dispensing motor 5 to drive the dispensing roller 4 in step S1 to rotate by a fixed angle (45° in this embodiment). At this time, the injection 15 in the lowermost receiving groove 401 falls out of the receiving groove 401 under its own gravity and falls smoothly and accurately into the designated slot of the inner tray box 14 below through the dropping hole 801 and the guide cylinder 9. S4, the conveying speed of the inner tray 14 on the conveyor belt 11 is synchronized with the rotational feeding speed of the dispensing roller 4, and the injection 15 is sequentially dispensed into each slot of the inner tray 14. When the inner tray 14 leaves the detection position of the detection sensor, the dispensing motor 5 stops, and the dispensing and dispensing work of one inner tray 14 is completed. S5, when the next empty inner tray 14 is delivered to the detection position of the detection sensor, the process of S2-S4 is repeated, thereby realizing fully automatic and continuous boxing operation.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
