Description

Technical Field

[0001] This utility model relates to the field of pallet manufacturing technology, specifically to a device for stacking blister pallets in both forward and reverse directions. Background Technology

[0002] Blister trays are plastic packaging containers made using vacuum forming technology, primarily using materials such as PET and PVC. They are lightweight, durable, shockproof, and moisture-proof. Their structure can precisely conform to the shape of products and are widely used in industries such as electronics, food, and pharmaceuticals. They combine protection and display functions, support customized designs, and are environmentally friendly and recyclable, making them an ideal choice for efficient transportation and warehousing. In the production of blister trays, after forming and demolding, the trays need to be handled, stacked, and packaged using a vacuum forming mechanism. However, when stacking blister trays, due to their thin walls, the stacked trays fit together very closely, making them difficult for consumers to separate, causing inconvenience.

[0005] Furthermore, the upper end of the rotating base is a grooved wheel mechanism, which can rotate 180° intermittently, and the conveyor belt is installed on the grooved wheel mechanism.

[0006] Furthermore, the grooved wheel mechanism includes a dial and a grooved wheel. The dial is provided with two pins and an arc-shaped boss. The grooved wheel is provided with four grooves and four arc-shaped notches arranged in a circular array. The grooves and arc-shaped notches are alternately arranged. The diameter of the pins corresponds to the width of the grooves. The outer contour of the arc-shaped boss corresponds to the contour of the arc-shaped notches. The two pins can be slidably connected in adjacent grooves of the four grooves and continuously rotate the grooved wheel 180°. The arc-shaped boss can continuously slide and abut against the arc-shaped notches 180° and keep the grooved wheel stationary. The rotation of the grooved wheel 180° and the stationary position of the grooved wheel are alternated. The conveyor belt is installed on the grooved wheel.

[0016] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0017] like Figure 1-3 As shown, a forward and reverse stacking device for blister trays includes a rotating base 1, a conveyor belt 9, a lifting mechanism 2, a traversing mechanism 3, and an adsorption mechanism. The conveyor belt 9 is mounted on the rotating base 1, the lifting mechanism 2 is mounted on the side of the rotating base 1, the front end of the lifting mechanism 2 is a lifting plate 201, the traversing mechanism 3 is mounted on the lifting plate 201, the front end of the traversing mechanism 3 is a sliding plate 301, the adsorption mechanism is mounted on the sliding plate 301, and the output end of the adsorption mechanism is a suction head 7, which faces downward and is located above the conveyor belt 9. The device is controlled by the lifting mechanism 2 and the traversing mechanism 3. The suction head 7 of the suction mechanism moves above the blister tray and descends, sucking up the blister tray and then transporting it onto the conveyor belt 9. At this time, the rotating base 1 drives the blister tray to rotate 180°. During this period, the suction mechanism continues to transport new blister trays for stacking, forming a structure of alternating forward and reverse stacking on the conveyor belt 9. Due to the asymmetry at both ends of the blister trays, after the blister trays are stacked, the upper blister tray will not completely sink into the lower blister tray, avoiding complete adhesion between the blister trays and making it easy to separate the blister trays during use.

[0018] In the above embodiment, the upper end of the rotating base 1 is a Geneva mechanism, which can rotate intermittently by 180°. The conveyor belt 9 is installed on the Geneva mechanism. The Geneva mechanism has the advantages of simple structure, reliable operation, and smooth movement. When applied to this device, it can replace the working mode of the motor frequently starting and stopping to drive the conveyor belt 9 to rotate intermittently by 180° under the transmission mode, thus avoiding motor burnout. At the same time, the starting and stopping impact of the Geneva mechanism is small, and when it drives the conveyor belt 9 to rotate, it has almost no effect on the blister tray, thus avoiding displacement of the blister tray during rotation, which would lead to inaccurate stacking of the blister tray. The Geneva mechanism includes a motor, a dial 11, and a Geneva wheel 10. The motor is built into the rotating base 1, and its output end is connected to the dial 11. The dial 11 has two pins 12 and an arc-shaped boss 13. The Geneva wheel 10 has four circumferentially arranged grooves 1002 and four arc-shaped notches 1001, with the grooves 1002 and notches 1001 alternating. The diameter of the pins 12 corresponds to the width of the grooves 1002, and the outer contour of the arc-shaped boss 13 corresponds to the contour of the arc-shaped notches 1001. The arc-shaped boss 13 and the arc-shaped notches 1001 are equivalent to the locking arc in the Geneva mechanism. By adjusting the structure, position and corresponding parameters using technical means, the two pins 12 can be slidably connected to the adjacent slides 1002 in the four slides 1002 and continuously rotate the groove wheel 10 to 180°. The arc-shaped boss 13 can continuously slide and abut against the arc-shaped notch 1001 to 180° and keep the groove wheel 10 stationary. The rotation of the groove wheel 10 to 180° and the keeping of the groove wheel 10 stationary are alternated, so that the conveyor belt 9 installed on the groove wheel 10 rotates intermittently by 180°. Without stopping the motor, the continuous forward and reverse stacking action of automatically rotating 180° for each layer of the blister tray is stacked is realized.

[0019] The adsorption mechanism includes a crossbeam 4, a support 6, an air pump 5, and suction heads 7. One end of the crossbeam 4 is mounted on a sliding plate 301. The air pump 5 and the support 6 are respectively mounted on the crossbeam 4. The suction heads 7 are mounted on the support 6, and the suction heads 7 are connected to the air pump 5 via an air pipe 8. The suction heads 7 are linearly arrayed on the support 6, and the support 6 is linearly arrayed on the crossbeam 4, allowing for the simultaneous handling of multiple sets of blister trays. The support 6 has a horizontal groove 601 in the middle, and the suction heads 7 are located in the horizontal groove 601. The suction heads 7 can be adjusted in position and fixed to the support 6 by nuts 704 to ensure that the suction heads 7 are aligned with the center of the blister tray during operation, ensuring even force distribution during handling. The suction head 7 includes an air cylinder 701, a spring 702, and a suction nozzle 703. The air cylinder 701 is located in the transverse groove 601 and is fixed to the bracket 6 by a nut 704. An air chamber is provided inside the air cylinder 701. The upper end of the suction nozzle 703 is slidably connected to and communicates with the air chamber, and the lower end of the suction nozzle 703 extends downwards out of the air chamber. The spring 702 is located in the air chamber at the upper end of the suction nozzle 703. One end of the air pipe 8 is connected to the air pump 5, and the other end is connected to the air chamber. Under the action of the lifting mechanism 2, before the suction head 7 moves downwards to absorb the blister tray, the suction nozzle 703 first... When the nozzle 703 contacts the blister tray, the spring 702 located in the air chamber is compressed, providing a buffer for the nozzle 703 to contact the blister tray, avoiding damage to the blister tray or causing the blister tray to deviate from its position; when the nozzle 7 lifts the blister tray upwards, the spring 702 pushes the nozzle 703 open; when the blister tray is transported to the conveyor belt 9 for stacking, the spring 702 also provides a certain buffer for the stacking work, avoiding the blister tray from being pressed down and causing the spacing between the stacked blister trays to be too small, and also avoiding the impact of the downward pressure on the neatly stacked blister trays and causing them to deviate from their position.

[0020] Description of the working principle of this utility model:

[0021] After the blister tray is formed and demolded, it is located in the buffer area of ​​the previous process on the same production line. The lifting mechanism 2 and the transverse mechanism 3 of this device jointly move the suction mechanism above the blister tray. Then, the lifting mechanism 2 drives the suction head 7 to descend, and the suction mechanism provides negative pressure to suck up the blister tray. Subsequently, the lifting mechanism 2 lifts it up and the transverse mechanism 3 transports it laterally to the top of the conveyor belt 9. Finally, it descends and releases, placing the blister tray on the conveyor belt 9. After each set of blister trays is stacked, the grooved wheel mechanism drives the conveyor belt 9 to rotate 180° to perform forward and reverse stacking operations, avoiding complete adhesion between the blister trays and making them easy to separate during use. When a certain number of blister trays are stacked, the conveyor belt 9 starts and transports the layered blister trays longitudinally to the terminal packaging area, where the forward and reverse stacking operations of the next batch of blister trays can then be carried out.
