Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging technology, specifically a cartoning machine applied to pharmaceutical packaging. Background Technology

[0002] Pharmaceutical packaging refers to the process of using appropriate materials or containers and packaging technology to dispense (fill), seal, pack, and label semi-finished or finished pharmaceutical preparations, thereby providing quality assurance, trademark identification, and instructions for the pharmaceutical products.

[0003] Currently, when packaging medicines, multiple sealed medicine boxes need to be grasped as a whole, placed into a carton, and then sent to a sealing machine for sealing. Existing technology mostly uses suction cups to grasp medicine boxes. However, since the size of the suction cup is fixed, while the size of the medicine box can change, the suction cup cannot adjust the suction force according to the weight of the medicine box. When the medicine box is heavy, it will detach from the suction cup, which will affect the packaging process. Utility Model Content

[0004] The purpose of this invention is to provide a cartoning machine for pharmaceutical packaging, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cartoning machine for pharmaceutical packaging, used to place pharmaceuticals into cartons, includes a first conveyor belt and a second conveyor belt. A traction assembly is installed between the first and second conveyor belts. An adsorption assembly is installed on the traction assembly. The adsorption assembly includes a first vacuum suction cup, a second vacuum suction cup, a first connecting plate, and a second connecting plate. The first vacuum suction cup is fixedly installed on the first connecting plate, and the first connecting plate is installed on the traction assembly. The second connecting plate is fixedly installed on the first connecting plate. The second vacuum suction cup is vertically slidably connected to the side of the second connecting plate. A drive assembly connects the second vacuum suction cup and the second connecting plate.

[0007] Preferably, the drive assembly includes a traction rod, a rack, a gear, a support arm, and a bracket. The bracket is fixedly mounted on the second connecting plate. The traction rod is vertically fixedly connected to the traction assembly. The rack is fixedly mounted on the side wall of the traction rod. One end of the support arm is hinged to the second vacuum suction cup, and the other end of the support arm is fixedly mounted on the gear. The gear is rotatably connected inside the bracket and engages with the rack.

[0008] Preferably, the adsorption assembly further includes a spring and a telescopic rod, both of which are fixedly connected between the traction assembly and the first connecting plate.

[0009] Preferably, the traction assembly includes a top plate, a motor, a base, a machine base, and an electric slide. The base is fixedly installed between the first conveyor belt and the second conveyor belt. The motor is fixedly installed at the bottom of the base. The machine base is rotatably connected to the top of the base via the motor. The electric slide is fixedly installed on the machine base. The top plate is fixedly installed on the slider of the electric slide. The top ends of the traction rod, spring, and telescopic rod are all fixedly connected to the bottom of the top plate.

[0010] Preferably, the adsorption assembly further includes a guide rod, the bottom end of which is fixedly connected to a first connecting plate, and the top end of which is vertically slidably connected to a top plate.

[0011] Preferably, a limiting ring is fixedly installed on the guide rod, and the top surface of the limiting ring abuts against the bottom surface of the top plate.

[0012] Preferably, a counterweight is fixedly installed on the side of the second vacuum suction cup, and the overall center of gravity of the second vacuum suction cup and the counterweight is located directly below the hinge point between the second vacuum suction cup and the support arm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model uses a first suction cup to grip and hold the medicine box. When the weight of the medicine box exceeds the spring force, the drive component can drive the second suction cup to descend and contact the top surface of the medicine box, thus gripping and holding the medicine box. Through the cooperation of the first and second suction cups, the suction force on heavier medicine boxes is increased, thereby achieving stable loading of heavier medicine boxes.

[0021] 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.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution:

[0023] A cartoning machine for pharmaceutical packaging, used to place pharmaceuticals into cartons 3, includes a first conveyor belt 1 and a second conveyor belt 2. A traction assembly 5 is installed between the first conveyor belt 1 and the second conveyor belt 2. An adsorption assembly 6 is installed on the traction assembly 5. The adsorption assembly 6 includes a first vacuum suction cup 61, a second vacuum suction cup 62, a first connecting plate 63, and a second connecting plate 64. The first vacuum suction cup 61 is fixedly installed on the first connecting plate 63, and the first connecting plate 63 is installed on the traction assembly 5. The second connecting plate 64 is fixedly installed on the first connecting plate 63. The second vacuum suction cup 62 is vertically slidably connected to the side of the second connecting plate 64. A drive assembly 7 is connected between the second vacuum suction cup 62 and the second connecting plate 64.

[0024] Please see Figures 1 to 3 This embodiment consists of two parallel conveyor belts, namely the first conveyor belt 1 and the second conveyor belt 2. The first conveyor belt 1 is used to transport the medicine box 4, and the second conveyor belt 2 is used to transport the carton 3. A traction component 5 is installed between the two, and an adsorption component 6 is suspended on the traction component 5 to grab the medicine box 4 and transfer it to the carton 3. The adsorption component 6 includes a first vacuum suction cup 61 and a second vacuum suction cup 62, which work together to accommodate medicine boxes 4 of different weights.

[0025] The drive assembly 7 includes a traction rod 71, a rack 72, a gear 73, a support arm 74, and a bracket 75. The bracket 75 is fixedly mounted on the second connecting plate 64. The traction rod 71 is vertically fixedly connected to the traction assembly 5. The rack 72 is fixedly mounted on the side wall of the traction rod 71. One end of the support arm 74 is hinged to the second vacuum suction cup 62, and the other end of the support arm 74 is fixedly mounted on the gear 73. The gear 73 is rotatably connected inside the bracket 75 and cooperates with the rack 72.

[0026] Please see Figure 5 When the traction rod 71 moves upward, the traction rod 71 can drive the rack part 72 to move synchronously. At this time, the rack part 72 can drive the gear 73 to rotate, which in turn causes the gear 73 to drive the support arm 74 to rotate, so that one end of the support arm 74 can drive the second vacuum suction cup 62 to descend, so that the second vacuum suction cup 62 can adsorb and fix the medicine box 4.

[0027] The adsorption assembly 6 also includes a spring 65 and a telescopic rod 66, both of which are fixedly connected between the traction assembly 5 and the first connecting plate 63.

[0028] The traction assembly 5 includes a top plate 51, a motor 52, a base 53, a base 54, and an electric slide 55. The base 53 is fixedly installed between the first conveyor belt 1 and the second conveyor belt 2. The motor 52 is fixedly installed at the bottom of the base 53. The base 54 is rotatably connected to the top of the base 53 via the motor 52. The electric slide 55 is fixedly installed on the base 54. The top plate 51 is fixedly installed on the slider of the electric slide 55. The top ends of the traction rod 71, the spring 65, and the telescopic rod 66 are all fixedly connected to the bottom of the top plate 51.

[0029] Please see Figure 3 Motor 52 drives base 54 to rotate, and base 54 drives top plate 51 to rotate synchronously via electric slide 55, which in turn drives adsorption assembly 6 to rotate synchronously, so as to transfer the adsorbed and fixed medicine box 4 from the first conveyor belt 1 to the second conveyor belt 2 for boxing. Electric slide 55 drives top plate 51 to move down, causing first connecting plate 63 and first vacuum suction cup 61 to contact medicine box 4. If the weight of medicine box 4 is less than the preset elastic force of spring 65, spring 65 remains extended, and only the first vacuum suction cup 61 is in contact with the medicine box 4. When the top plate 51 of the medicine box 4 is lifted, the first vacuum suction cup 61 lifts the medicine box 4 and transfers it to the carton 3. When the weight of the medicine box 4 exceeds the elastic force of the spring 65, the first connecting plate 63 will stretch the spring 65 when it is lifted. At this time, the first connecting plate 63 will also drive the drive rod to move synchronously. The rack part 72 of the traction rod 71 pushes the gear 73 to rotate, which drives the support arm 74 to press down the second vacuum suction cup 62. The second vacuum suction cup 62 descends to contact the top surface of the medicine box 4 and is simultaneously adsorbed with the first vacuum suction cup 61, providing dual suction.

[0030] The adsorption assembly 6 also includes a guide rod 67. The bottom end of the guide rod 67 is fixedly connected to the first connecting plate 63, and the top end of the guide rod 67 is vertically slidably connected to the top plate 51. A limiting ring 9 is fixedly installed on the guide rod 67, and the top surface of the limiting ring 9 abuts against the bottom surface of the top plate 51.

[0031] Please see Figure 4 When the top plate 51 is pressed down, the top plate 51 can drive the first vacuum suction cup to contact the medicine box 4 through the first connecting plate 63. Due to the presence of the limiting ring 9, the top plate 51 cannot continue to press down the first vacuum suction cup.

[0032] A counterweight 8 is fixedly installed on the side of the second vacuum suction cup 62. The overall center of gravity of the second vacuum suction cup 62 and the counterweight 8 is located directly below the hinge point between the second vacuum suction cup 62 and the support arm 74.

[0033] Please see Figure 5 During the rotation of the second vacuum suction cup 62, the support arm 74 ensures that the second vacuum suction cup 62 remains vertical, so that the second vacuum suction cup 62 can contact the top surface of the medicine box 4.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
