Description

Technical Field

[0001] This utility model relates to an automated production equipment in the packaging field, specifically a plastic tray suction mechanism. Background Technology

[0002] With the development and modernization of manufacturing, the automation level of production lines has gradually increased, thus placing higher demands on production efficiency, safety, and stability. Plastic pallets play an important role in many production and logistics processes. They are often used for product packaging, storage, and transportation, playing a crucial role in ensuring product safety and integrity. However, one often overlooked but vital aspect is the process of picking up plastic pallets.

[0003] In traditional production environments, the handling of plastic pallets largely relies on manual labor. Workers must manually remove pallets one by one from large stacks and place them onto the production line. This method presents several significant problems:

[0004] 1. Inefficient: The speed of manual pallet retrieval is limited by human strength and manual operation, making it difficult to meet the continuous supply requirements of high-speed production lines.

[0005] 2. Safety hazards: Manually handling pallets may cause worker injuries, especially in continuous and repetitive operations, which can easily lead to fatigue and operational errors.

[0006] 3. Inconsistency issues: Inconsistencies in the way and speed of manual operation can lead to production line stagnation or accumulated errors.

[0007] 4. Cost issues: Long hours of manual operation increase labor costs and may require more training and management.

[0008] To address these issues, some manufacturers have attempted semi-automated plastic tray picking methods. While this reduces the need for manual tray handling, it still requires human intervention, especially when trays are not stacked neatly, are overstacked, or become jammed. Therefore, a highly efficient, stable, and automated plastic tray picking mechanism has become a pressing problem in the manufacturing industry. This mechanism must not only achieve fast and accurate picking but also possess sufficient stability and robustness to adapt to various production environments and handle potential anomalies. Utility Model Content

[0009] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a plastic tray suction and holding mechanism that is simple in structure, easy to use, and capable of automatically picking up and placing trays.

[0010] The objective of this utility model is achieved in the following way: a plastic tray suction mechanism, characterized in that: it includes a main frame and a tray supply mechanism and a tray suction mechanism disposed thereon, wherein:

[0011] The pallet supply mechanism includes a guide trough, the front end of which is an open outlet, and a baffle is provided on the side wall of the outlet. Several stacked pallets are placed in the guide trough and are restricted within the guide trough by the baffle.

[0012] The pallet supply mechanism includes a first rotating shaft rotatably mounted on the main frame. The first rotating shaft is connected to a swing shaft via a drive arm. Slide rails are provided at both ends of the swing shaft. The slide rails are connected to guide rails oscillatingly mounted on the main frame. The first rotating shaft is driven to rotate by a power mechanism, which in turn drives the swing shaft to oscillate.

[0013] The swing shaft is equipped with a suction cup. When the swing shaft moves to the discharge port, it picks up the tray. When the swing shaft moves to the unloading station, the suction cup releases the tray.

[0014] The feed trough is inclined, with the front lower than the back.

[0015] A pressure plate is slidably installed inside the guide trough. The pressure plate is located at the rear end of the guide trough and always pushes the tray forward.

[0016] The drive arm consists of at least two parts, which are symmetrically installed between the first rotating shaft and the swing shaft. The drive arm is equipped with a connecting arm that is connected to the power mechanism.

[0017] The power mechanism is a rotatable power wheel mounted on the main frame. A crank arm is connected to the power wheel, and one end of the crank arm is hinged to the connecting arm through a connecting rod. When the power wheel rotates, it drives the drive arm to swing through the crank arm and connecting rod.

[0018] The drive pulley is driven by a drive motor.

[0019] A suction cup frame is mounted on the swing shaft via a suction cup cylinder, and the suction cup is mounted on the suction cup frame.

[0020] At least two suction cup cylinders are provided, which are symmetrically mounted on the swing shaft.

[0021] The guide rail is rotatably mounted on the main frame via a hinge shaft.

[0022] The guide rail has several guide wheels on its end face, and a guide area is formed between the guide wheels. The guide rail is slidably installed in the guide area.

[0023] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness. 2. The automated pallet supply mechanism, through components such as a swing shaft and suction cups, accurately picks up and places plastic pallets, achieving continuous and uninterrupted material supply and effectively improving production efficiency. 3. The inclined design of the guide chute, with its lower front and higher rear, combined with the internal pressure plate, ensures that the plastic pallets can always move forward smoothly and stably during the operation of the mechanism, reducing material picking obstacles caused by uneven pallet stacking.

[0024] 4. The power mechanism drives the swing shaft to oscillate via connecting rods and linkages, achieving automatic pallet pickup and placement, ensuring consistency in operation and reducing human error. 5. Fully automated operation reduces the need for workers to directly participate in pallet handling, significantly lowering the risk of workplace injuries caused by repetitive labor. 6. The suction cup cylinder design allows for fine-tuning of the suction cup frame as needed, providing high operational flexibility. Furthermore, the rotatable guide rail and guide wheel design enhance the mechanism's adaptability to different production environments. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings. A plastic tray suction mechanism, characterized in that: it includes a main frame 1 and a tray supply mechanism and a tray suction mechanism disposed thereon, wherein:

[0031] The pallet supply mechanism includes a guide trough 2, the front end of which is an open outlet, and a baffle 21 is provided on the side wall of the outlet. Several stacked pallets 3 are placed in the guide trough 2 and are restricted within the guide trough 2 by the baffle 21.

[0032] The pallet supply mechanism includes a first rotating shaft 4 rotatably mounted on the main frame 1. The first rotating shaft 4 is connected to a swing shaft 6 via a drive arm 5. Slide rails 61 are provided at both ends of the swing shaft 6. The slide rails 61 are connected to guide rails 7 oscillatingly mounted on the main frame 1. The first rotating shaft 4 is driven to rotate by a power mechanism, which in turn drives the swing shaft 6 to oscillate.

[0033] The swing shaft 6 is equipped with a suction cup 8. When the swing shaft 6 moves to the discharge port, it picks up the tray 3. When the swing shaft 6 moves to the discharge station, the suction cup 8 releases the tray 3.

[0034] The feed trough 2 is inclined in a way that is shorter in the front and higher in the back.

[0035] A pressure plate 22 is slidably installed inside the guide trough 2. The pressure plate 22 is located at the rear end of the guide trough 2 and always pushes the tray 3 forward.

[0036] The drive arm 5 is provided in at least two parts, which are symmetrically installed between the first rotating shaft 4 and the swing shaft 6. The drive arm 5 is provided with a connecting arm 51 connected to the power mechanism.

[0037] The power mechanism is a power wheel 11 that is rotatably mounted on the main frame 1. A crank arm 12 is connected to the power wheel 11. One end of the crank arm 12 is hinged to the connecting arm 51 through a connecting rod 13. When the power wheel 11 rotates, it drives the drive arm 5 to swing through the crank arm 12 and the connecting rod 13.

[0038] The power wheel 11 is a pulley, which is connected to the drive pulley 16 via a transmission belt 15. The drive pulley 16 is driven by a drive motor 17.

[0039] A suction cup frame 82 is mounted on the swing shaft 6 via a suction cup cylinder 81, and the suction cup 8 is mounted on the suction cup frame 82.

[0040] At least two suction cylinders 81 are provided and are symmetrically mounted on the rocker shaft 6.

[0041] The guide rail 7 is rotatably mounted on the main frame 1 via a hinge shaft 71.

[0042] The guide rail 7 has several guide wheels 72 on its end face, and a guide area is formed between the guide wheels 72. The guide rail 7 is slidably installed in the guide area.

[0043] Working principle: When production begins, plastic trays 3 are stacked and placed into the guide chute 2. This guide chute 2 is designed to be lower at the front and higher at the back, allowing the plastic trays to slide naturally to the front end under gravity. Furthermore, there is a pressure plate 22 inside the guide chute 2, which holds the tray at the very rear of the chute and continuously propels it forward. This design not only ensures a continuous supply of plastic trays but also eliminates the risk of tray failure due to jamming or improper stacking.

[0044] Furthermore, it also includes a power and drive mechanism: its power source originates from a drive motor 17, which drives the active pulley 16, and then rotates the pulley 14, i.e., our power wheel 11, through the transmission belt 15. When the power wheel rotates, the drive arm 5 is swayed by the connection structure of the crank arm 12 and the connecting rod 13. This entire linkage design ensures the smooth transmission of power, allowing the swing shaft 6 to swing accurately and continuously. A suction cup 8 is fixed on the swing shaft 6. When it moves to the discharge port position of the guide trough, the suction cup is activated and tightly adsorbs the plastic tray 3 through the structure of the suction cup frame 82 and the suction cup cylinder 81. Subsequently, the suction cup cylinder 81 retracts, and the suction cup pulls the tray at the bottom outward. The suction cup, under its own deformation, breaks free from the restraint of the baffle and is taken out of the guide trough. The swing shaft continues its movement to the designated placement position, at which point the suction cup releases the plastic tray, completing a complete suction and placement process.

[0045] To ensure the smooth movement of the rocker shaft 6, the mechanism is designed with a guide rail 7, which is mounted to the main frame 1 via a hinge shaft 71. Furthermore, a guide wheel 72 is provided at the end of the guide rail, providing additional stability and guidance for the rocker shaft, ensuring the accuracy of overall operation.

[0046] Compared with traditional technologies, the structure in this case has the following advantages: 1. High efficiency: Compared with traditional manual or semi-automatic methods, this mechanism achieves fully automated material handling, significantly improving production efficiency. 2. Stability: The design of the guide chute, continuous pressure plate advancement, and precise power transmission ensure a continuous and stable pallet supply. 3. Economy: Simplified operation process reduces reliance on workers, resulting in significant savings in labor costs over long-term operation. 4. Safety: Fully automated operation reduces direct interaction between workers and machines, thereby reducing the risk of workplace injuries. Simultaneously, it ensures the continuity, stability, and safety of production, while also bringing significant economic benefits, thus making it widely applicable.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
