Description

Technical Field

[0001] This utility model belongs to the technical field of automated packaging equipment for ointment-type pharmaceuticals, and particularly relates to the insertion mechanism of a tube filling device. Background Technology

[0002] In pharmaceutical ointment production lines, after filling and sealing, the tubes need to be neatly and vertically placed into tube boxes for storage and transportation. Traditionally, this is done manually, which is inefficient, difficult to guarantee hygiene standards, and has high labor costs.

[0003] In the prior art, some automated feeding or sorting devices have emerged. For example, prior art with publication number CN117842694A discloses a cannula feeding fixture, which uses negative pressure grippers to pick up materials from a feeding cart, then uses pneumatic grippers to transfer them to a corrugated rack for leveling, and finally uses feeding grippers to punch holes for feeding. Although this device achieves automated material picking and leveling, its technical field focuses on the pre-punching treatment of medical cannulas. Its feeding action after leveling does not involve vertically placing the tubular material into the box, and its structural layout cannot solve the problem of picking up materials from a specific flipping mechanism and avoiding motion interference.

[0004] Another prior art publication, CN115744260A, discloses a propellant tube sorting device that uses a pushing, pitch-changing, and gripping mechanism to sort propellant tubes and densely place them into a receiving hopper. This device is mainly used in the field of ammunition preparation, and its core lies in pitch-changing to achieve high-density boxing. However, it does not involve transferring the flexible tubes from the flipping station and executing a specific interference-avoiding motion path of "vertical upward - horizontal movement - vertical downward" to meet the specific requirements of tube insertion into the box.

[0005] In summary, existing technologies lack an automated tube insertion mechanism specifically designed for ointment tube packaging in the pharmaceutical industry that can efficiently and without interference complete the process from the flipping station to the tube box. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, a tube insertion mechanism for a flexible tube filling device is provided, which is compact in structure, precise in action, efficient in operation, and can effectively avoid interference with the upstream flipping mechanism.

[0007] To solve the above-mentioned technical problems, this utility model provides: a tube insertion mechanism for a soft tube filling device, including a mechanism support frame, a main mounting plate on the mechanism support frame, a moving mechanism on the main mounting plate, and the moving direction of the moving mechanism being parallel to the upper surface of the main mounting plate;

[0008] The moving mechanism includes a first support plate and a first drive assembly that drives the first support plate to move in a direction parallel to the main mounting plate;

[0009] The first support plate is provided with a claw picking and placing mechanism, and the moving direction of the claw picking and placing mechanism is perpendicular to the upper surface of the first support plate.

[0010] The front end of the main mounting plate is also equipped with a hose insertion mechanism.

[0011] The clamping mechanism includes a clamping jaw assembly for clamping the end of the hose, and the hose loading mechanism includes a hose placement slot for receiving the inverted hose and placing it into the hose box.

[0012] The hose tail is clamped by the gripper mechanism, and then the hose is moved by the moving mechanism to invert the hose into the hose box mechanism. Finally, the hose is placed into the hose box by the hose box mechanism.

[0013] In one feasible embodiment, the moving mechanism includes a pair of guide rails mounted on a main mounting plate, each guide rail having a slider, and a first support plate fixed to the slider.

[0014] In one feasible embodiment, the claw pick-and-place mechanism includes a claw support frame that is vertically mounted on a first support plate, the front end of the claw support frame having a claw support plate, and the lower part of the claw support plate being connected to the output end of a telescopic cylinder.

[0015] A servo motor-driven linear actuator is fixed on the chuck support plate, a chuck base is fixed on the servo motor-driven linear actuator, and a chuck assembly with the chuck opening facing downwards is fixed on the chuck base.

[0016] In one feasible embodiment, the jaw assembly includes several jaw units arranged evenly, each jaw unit including a pneumatic two-finger gripper, the end of which is provided with a clamping claw.

[0017] In an implementable manner, the hose insertion mechanism includes a pair of vertically extending and downwardly retracting second telescopic cylinders located at the front end of the main mounting plate. Each second telescopic cylinder is connected to a connecting rod, which extends forward to form an extension arm. A hose placement groove is provided between the extension arms.

[0018] The second telescopic cylinder is used to drive the hose placement slot to move vertically so that the hose can be placed into the hose box.

[0019] In one feasible embodiment, the hose placement groove includes vertical end rods fixed to the extension arm, a retaining plate between the vertical end rods that restricts the position of the embedded hose, and baffles protecting the hose provided before and after the retaining plate.

[0020] The beneficial effects of this utility model are as follows:

[0021] By combining the vertical movement of the gripper pick-and-place mechanism, the horizontal movement of the moving mechanism, and the vertical movement of the hose insertion mechanism, a precise path for the hose to be "vertically gripped, vertically lifted, horizontally transferred, and vertically placed into the box" is achieved, completely avoiding motion interference with the upstream flipping mechanism.

[0022] Furthermore, the combination of a servo motor-driven linear actuator and a pneumatic gripper ensures fast and precise gripping and movement. In conjunction with the guide rail slider mechanism, it guarantees the stability and reliability of the mechanism under high-speed operation (up to 180 pieces / minute or more).

[0023] The entire system is specifically designed for the pharmaceutical industry's tube packaging, featuring an easy-to-clean and maintain structure that meets GMP requirements. The unique design of the tube loading mechanism ensures stable tube positioning and neat placement within the box during transfer and descent.

[0024] By integrating and controlling the actions of each cylinder, servo motor, and sensor through PLC, the entire process from grabbing to placing into the box is automated, significantly improving production efficiency and automation level. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1 and Figure 2The diagram shows a schematic of the insertion mechanism of the flexible tube filling device of this utility model. It can be seen that the insertion mechanism of the flexible tube filling device includes a mechanism support frame 1, which provides a stable mounting base for the entire mechanism. A main mounting plate 2 is provided on the mechanism support frame 1, and a moving mechanism 3 is provided on the main mounting plate 2. The moving direction of the moving mechanism 3 is parallel to the upper surface of the main mounting plate 2. The moving mechanism 3 includes a first support plate 31 and a first driving assembly 33 that drives the first support plate 31 to move horizontally in a direction parallel to the main mounting plate 2. A claw picking and placing mechanism 4 is provided on the first support plate 31, and the moving direction of the claw picking and placing mechanism 4 is perpendicular to the upper surface of the first support plate 31. A flexible tube insertion mechanism 5 is also provided at the front end of the main mounting plate 2. The claw picking and placing mechanism 4 includes a claw assembly 45 for clamping the tail of the flexible tube, and the flexible tube insertion mechanism 5 includes a flexible tube placement groove 53 for receiving inverted flexible tubes and placing them into a flexible tube box.

[0030] The moving mechanism 3 includes a pair of guide rails 30 mounted on the main mounting plate 2, each guide rail 30 having a slider 32, and a first support plate 31 fixed on the slider 32.

[0031] The claw pick-and-place mechanism 4 includes a claw support frame 41 that is vertically mounted on the first support plate 31. The front end of the claw support frame 41 has a claw support plate 42, and the lower part of the claw support plate 42 is connected to the output end of the first drive assembly 33.

[0032] The first drive component 33 is a servo motor with a synchronous belt or lead screw, or a rodless cylinder. Its output end is connected to the claw support plate 42. By acting on the claw support plate 42, the horizontal movement of the first support plate 31 can be precisely controlled.

[0033] A servo motor-driven linear actuator 43 is fixed on the gripper support plate 42. A gripper base 44 is fixed on the servo motor-driven linear actuator 43. A gripper assembly 45 with the gripper opening facing downwards is fixed on the gripper base 44. The gripper assembly 45 includes several evenly arranged gripper units, each gripper unit including a pneumatic two-finger gripper, with a clamping claw at its end. The linear actuator 43 can finely adjust the vertical position of the gripper assembly 45 to ensure the accuracy of the gripping position.

[0034] At the front end of the main mounting plate 2, away from the mechanism support frame 1, a hose insertion mechanism 5 is provided. The hose insertion mechanism 5 includes a pair of vertically extending and downward-retracting second telescopic cylinders 51 located at the front end of the main mounting plate 2. The second telescopic cylinders 51 drive the hose placement groove 53 to move vertically to place the hose into the hose box. Each second telescopic cylinder 51 is connected to a connecting rod, which extends forward to form an extension arm 52. A hose placement groove 53 is provided between the extension arms 52. The hose placement groove 53 includes vertical end rods 530 fixed to the extension arms 52. A retaining plate 531 is provided between the vertical end rods to restrict the position of the inserted hose. The retaining plate 531 has multiple slots that match the shape of the hose to be packaged, used to restrict the position of the hose. Baffles 532 are also provided on the front and rear sides of the retaining plate 531 to prevent the hose from accidentally falling off during transfer.

[0035] Initially, the moving mechanism 3 is in the rear position, and the gripper mechanism 4 is in the lower gripping position under the action of the linear actuator 43. After the upstream flipping mechanism delivers the hose to the gripping station, the pneumatic two-finger gripper of the gripper assembly 45 actuates to clamp the tail of the hose.

[0036] Subsequently, the linear actuator 43 actuates, driving the gripper pick-and-place mechanism 4 to move vertically upward, lifting the hose out of the flipping box of the flipping mechanism. This vertical upward movement path effectively avoids collision and interference with the flipping mechanism.

[0037] After the hose is completely removed from the interference zone, the first drive component 33 of the moving mechanism 3 is activated, driving the first support plate 31 and the entire claw picking and placing mechanism 4 to move forward (towards the hose entering the box mechanism 5) horizontally.

[0038] When the hose is moved to the hose placement slot 53 of the hose loading mechanism 5, the linear actuator 43 of the gripper picking and placing mechanism 4 drives the gripper group 45 to move downward, inverting the hose and accurately placing it into the slot of the hose placement slot 53, and then the pneumatic two-finger gripper releases.

[0039] Finally, the second telescopic cylinder 51 of the hose insertion mechanism 5 actuates, driving the entire hose placement slot 53 to move vertically downwards until the hose is completely placed into the hose box below. Then, the second telescopic cylinder 51 retracts, ready for the next feeding. The entire process is controlled by a PLC program, repeating cyclically to achieve high-speed automated production.

[0040] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
