Description

Technical Field

[0001] This utility model belongs to the field of blister box processing, and in particular relates to a blister box unloading and stacking device. Background Technology

[0002] Blister boxes can be used to load products, protecting them from dust and facilitating their transport and storage. They ensure that products remain clean and intact before use. Blister boxes are lightweight, thin, and easy to process and shape, and can package and hold any irregularly shaped products.

[0003] After the blister packs are manufactured, they are typically stacked using a palletizing device. Existing palletizing devices generally consist of suction cups and a palletizing rack, with the rack capable of vertical movement. During stacking, the suction cups transfer the blister packs one by one to the palletizing rack. Because the blister packs are relatively thin, once a certain number of packs have accumulated on the rack, it moves downwards one station. While this method can complete the palletizing process, it cannot guarantee that the stacked blister packs will be neatly arranged, resulting in poor stacking quality. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a blister box unloading and stacking device, which aims to solve the problem that existing blister box unloading and stacking devices cannot ensure the neat stacking of stacked blister boxes, resulting in poor stacking quality.

[0005] The present invention adopts the following technical solution:

[0006] The blister box unloading and stacking device includes a base frame with a partition dividing it into left and right unloading sections. A vertically movable unloading rack is located within each unloading section on the base frame. The base frame has blocking mechanisms on its left, right, and front sides, with the front blocking mechanism capable of lateral sliding. Each blocking mechanism includes an inner and outer sliding block and a vertical frame, with the sliding block slidably installed and the vertical frame fixedly installed. A baffle is provided on the sliding block, and an adjusting plate slides vertically on the vertical frame. Several sets of support rods are rotatably mounted on the front of the adjusting plate from top to bottom, with the other ends of the support rods rotatably mounted at corresponding positions on the baffle. An adjusting screw is rotatably mounted on the vertical frame, with an adjusting screw sleeve fitted onto it. The adjusting screw sleeve is connected to the back of the adjusting plate. An adjusting motor for driving the adjusting screw rotation is also provided on the vertical frame.

[0007] Furthermore, the unloading rack has a clearance opening on the baffle on the same side.

[0008] Furthermore, the bottom of the front baffle mechanism is a slide plate, which is slidably mounted on the base frame. The base frame is equipped with a sliding cylinder, and the drive shaft of the sliding cylinder is connected to the slide plate.

[0009] Furthermore, a pair of left and right lifting screws are rotatably mounted on the base frame, and a lifting screw sleeve is fitted on the lifting screw. The unloading frame is slidably mounted on the base frame, and the back of the unloading frame is connected to the lifting screw sleeve. A driven pulley is provided at the bottom of the lifting screw, and a lifting motor is provided at the bottom of the base frame. The drive shaft of the lifting motor is provided with a driving pulley, and a belt is fitted between the driving pulley and the driven pulley.

[0010] Furthermore, the bottom surface of the base frame has stepped fixing grooves corresponding to each belt. A connecting shaft is provided in the fixing groove, and the connecting shaft is narrow at the top and wide at the bottom. A fixing nut is screwed into the top of the connecting shaft, and the fixing nut installs the connecting shaft in the fixing groove. A pressure wheel is rotatably provided below the connecting shaft, and the pressure wheel abuts against the belt.

[0011] The beneficial effects of this utility model are as follows: When the produced blister boxes arrive at the unloading position via conveyor, the unloading suction cup adheres to the blister boxes and moves them toward the unloading area on the same side. At this time, the unloading rack is at its highest position. After the unloading suction cup transfers the current blister box to the unloading rack, it continues to transfer the next blister box into the unloading area. The next blister box is then stacked on top of the current blister box. Because the blister boxes are relatively thin, during the stacking process, the unloading suction cup transfers a certain number of blister boxes and stacks them onto the unloading rack on the same side. The unloading rack then moves downward a short distance. After that, the unloading suction cup transfers a certain number of blister boxes and stacks them into the unloading area in turn. This cycle continues until the unloading area is full. Finally, the stack of blister boxes in the unloading area is transferred to the packaging station for packaging. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0017] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0018] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0019] Combination Figure 1-2 As shown, the blister box unloading and stacking device includes a base frame 1, on which a partition 2 is provided, dividing the base frame 1 into left and right unloading sections. A vertically movable unloading rack 3 is provided on the base frame 1 within each unloading section. Material blocking mechanisms are provided on the left, right, and front sides of the base frame 1, such as... Figure 1 The left-side material blocking mechanism is marked as 241, the right-side material blocking mechanism as 242, and the front-side material blocking mechanism as 243. The front-side material blocking mechanism 243 can slide laterally. This mechanism includes an inner and outer sliding block 4 and a vertical frame 5. The sliding block 4 is slidably installed, while the vertical frame 5 is fixedly installed. A baffle 6 is provided on the sliding block 4. An adjusting plate 7 is vertically slidably installed on the vertical frame 5. Several sets of support rods 8 are rotatably mounted on the front of the adjusting plate 7 from top to bottom. The other end of each support rod 8 is rotatably mounted on the corresponding position of the baffle 6. An adjusting screw 9 is rotatably mounted on the vertical frame 5. An adjusting screw sleeve 10 is fitted onto the adjusting screw 9 and connected to the back of the adjusting plate 7. An adjusting motor 11 for driving the adjusting screw 9 to rotate is also provided on the vertical frame 5.

[0020] Blister boxes can be used to load and protect products from dust, facilitating product transportation and storage, and ensuring that products remain clean and intact before use. Once the blister boxes are manufactured, this device can be used to unload and stack them.

[0021] This device includes a base frame with a partition inside, dividing the base frame into left and right unloading sections. Each unloading section contains an unloading rack that can move up and down. In practice, unloading suction cups are installed above both unloading sections, and each unloading rack can independently perform material stacking work according to the actual situation of the production line, without interfering with each other.

[0022] In this structure, the unloading rack serves as a carrier for receiving blister boxes. When a finished blister box is conveyed to the unloading position, the unloading suction cup picks up the blister box and moves it towards the unloading area on the same side. At this time, the unloading rack is at its highest position. After the unloading suction cup transfers the current blister box to the unloading rack, it continues to transfer the next blister box into the unloading area, stacking the next blister box on top of the current one. Because the blister boxes are relatively thin, during the stacking process, the unloading suction cup transfers a certain number of blister boxes and stacks them on the unloading rack on the same side. The unloading rack then moves downwards a short distance, and the unloading suction cup continues to transfer and stack a certain number of blister boxes into the unloading area. This cycle continues until the unloading area is full. Finally, the stack of blister boxes in the unloading area is transferred to the packaging station for packaging.

[0023] In this structure, the size of the feeding zone is matched to the size of the blister box. This ensures greater stability during the feeding and stacking process and results in neater stacking. In practice, the size of the two feeding zones can be adjusted by changing the lateral position of the left and right sets of baffles to accommodate blister boxes of different sizes. Furthermore, during stacking, the front baffle moves towards the two feeding zones at regular intervals, leveling the stacked blister boxes and improving their neatness and stacking quality.

[0024] When adjusting the size of the two feeding zones by changing the lateral position of the left and right sets of baffles, to reduce the size of the feeding zone to accommodate a smaller blister box, the two adjusting motors start working. These motors drive the adjusting screw to rotate, causing the adjusting screw sleeve to move upwards along the screw, and the adjusting plate to move upwards accordingly. As the adjusting plate moves upwards, the support rod on it pushes the baffle on the same side to slide inwards. During this inward sliding of the two sets of baffles, the size of the two feeding zones gradually decreases until the adjustment is complete. In practice, the left and right sets of baffles can also be adjusted independently.

[0025] In this device, such as Figure 1 The bottom of the front baffle mechanism 243 is a slide plate 12, which is slidably mounted on the base frame 1. The base frame 1 is provided with a sliding cylinder 13, and the drive shaft of the sliding cylinder 13 is connected to the slide plate 12.

[0026] During the stacking process of blister packs, the front baffle levels the stacked blister packs on the left and right unloading racks at regular intervals. During this leveling process, the front baffle mechanism switches between the two positions via a sliding cylinder. Once switched into position, the front baffle moves longitudinally toward the unloading rack on the same side, leveling the stacked blister packs there. Similarly, when the front baffle needs to move longitudinally, the front adjusting motor drives the adjusting screw to rotate, and the corresponding adjusting screw sleeve moves along the height of the adjusting screw, causing the front baffle to move longitudinally toward the unloading rack on the same side.

[0027] In the diagram, the left and right baffle mechanisms each have two baffles, while the front baffle mechanism has one baffle. The unloading rack 3 has a clearance opening 14 corresponding to the baffle 6 on the same side. During the movement of the baffle, the clearance opening helps to avoid obstruct the baffle.

[0028] As a specific structure, such as Figure 3 The base frame 1 is rotatably equipped with a pair of left and right lifting screws 15, and a lifting screw sleeve 16 is fitted on the lifting screw 15. The unloading frame 3 is slidably installed on the base frame 1, and the back of the unloading frame 3 is connected to the lifting screw sleeve 16. The bottom of the lifting screw 15 is provided with a driven pulley 17. The bottom of the base frame 1 is provided with a lifting motor 18. The drive shaft of the lifting motor 18 is provided with a driving pulley 19. A belt 20 is fitted between the driving pulley 19 and the driven pulley 17.

[0029] In this device, the two unloading racks can move up and down independently without interfering with each other. When the unloading rack moves vertically, the lifting motor on the same side starts working and drives the drive pulley to rotate. Under the linkage of the belt, the lifting screw rotates, and the lifting screw sleeve moves vertically along the height direction of the lifting screw, and the unloading rack moves vertically accordingly.

[0030] In addition, such as Figure 4 The bottom surface of the base frame 1 has a stepped fixing groove 21 corresponding to each belt 20. A connecting shaft 22 is provided in the fixing groove 21. The connecting shaft 22 is narrow at the top and wide at the bottom. A fixing nut (not shown in the figure) is screwed into the top of the connecting shaft 22. The fixing nut installs the connecting shaft 22 in the fixing groove 21. A pressure wheel 23 is rotatably provided below the connecting shaft 22. The pressure wheel 23 abuts against the belt 20.

[0031] In this structure, the fixing groove 21 includes a short groove 211, within which a shallow groove 212 is formed. In practice, the belt tension can be changed by adjusting the installation position of the pressure roller. Under the preload of the pressure roller, the belt rotates more stably. To adjust the installation position of the pressure roller, first loosen the fixing nut, then move the pressure roller. During the movement of the pressure roller, the connecting shaft moves within the fixing groove. After the pressure roller is adjusted, tighten the fixing nut.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
