[0001] The present invention belongs to the technical field of automatic pallet production, and particularly relates to an automatic production line for pallets. Background Art

[0002] In the field of automatic pallet production, the automation level of existing production equipment still has significant deficiencies. For example, during the transfer and stacking of pallets, the traditional stacking line design usually focuses on standardized products, such as the stacking of boxes and bagged goods. It relies on robotic arms, conveyor belts, and basic sensors. However, in the pallet production process, due to the structural diversity and size flexibility requirements of the pallets themselves, it is difficult for existing systems to achieve full automation and still rely on manual intervention. Especially during the pallet grasping and stacking process, manual adjustment or intervention is required, thus reducing the production efficiency of pallets.

[0003] The information disclosed in this background art section is only intended to increase the understanding of the overall background of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Invention

Detailed Embodiments

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Such as Figures 1-3As shown in the figure, the automated production line of the tray in an embodiment of the present invention includes an injection molding machine 1, a material receiving mechanism 2, a material picking robot arm 3, a trimming mechanism 4, and a stacking mechanism 5. The injection molding machine 1 is used to produce trays. The material receiving mechanism 2 is arranged downstream of the injection molding machine 1. The material picking robot arm 3 is arranged on the injection molding machine 1 and is used to move the tray from the injection molding machine 1 to the material receiving mechanism 2. The trimming mechanism 4 is arranged downstream of the material receiving mechanism 2 and is used to trim the sprue of the tray. The stacking mechanism 5 is arranged downstream of the trimming mechanism 4 and is used to stack multiple trimmed trays.

[0022] The stacking mechanism 5 includes: a stacking roller conveyor 51, a gantry 52, and two stacking rods 53. The stacking roller conveyor 51 is used to carry the trays trimmed by the trimming mechanism 4. The gantry 52 is arranged above the stacking roller conveyor 51. The two stacking rods 53 are connected to the gantry 52 and extend along the length direction of the stacking roller conveyor 51 and are respectively arranged on both sides of the stacking roller conveyor 51. The two stacking rods 53 can approach or move away from each other to clamp or release the tray. The stacking rod 53 can move up and down along the gantry 52 to stack the trays.

[0023] The working principle of the automated production line of the tray is as follows: The injection molding machine 1 produces trays through the injection molding process. The material picking robot arm 3 takes out the tray and places it on the material receiving mechanism 2. The material receiving mechanism 2 conveys the tray to the trimming mechanism 4, and the trimming mechanism 4 trims the sprue on the tray and cuts off the excess sprue. Then the tray is conveyed to the stacking roller conveyor 51 of the stacking mechanism 5. The two stacking rods 53 approach each other to clamp the tray and move upward along the gantry 52 to lift the tray. When the next tray moves to the stacking roller conveyor 51, the stacking rod 53 clamps the tray and moves downward to place the clamped tray on the surface of the tray on the stacking roller conveyor 51, thereby realizing the stacking of two trays. Then, the two stacking rods 53 move away from each other and continue to move downward to reach the bottom tray. Next, the two stacking rods 53 approach each other to clamp the bottom tray and move upward to lift the two stacked trays together. When the next tray moves to the stacking roller conveyor 51, the two stacked trays are placed on the surface of this tray. And so on, realizing the stacking of multiple trays.

[0024] In the above embodiment, the automated production line of the tray of the present invention realizes the automated production of trays by integrating the material receiving mechanism 2, the material picking robot arm 3, the trimming mechanism 4, and the stacking mechanism 5 without manual intervention. The stacking mechanism 5 can realize the automatic stacking of trays. Compared with stacking using a robot arm, the accuracy is better, and the stacked trays are not easily offset.

[0025] In one embodiment, as Figure 3As shown in the figure, a moving frame 54 is provided on the gantry 52. The moving frame 54 is slidably arranged on the gantry 52 in the up-and-down direction. The moving frame 54 is connected to the stacking rod 53 and can drive the stacking rod 53 to move up and down along the height direction of the gantry 52. The moving frame 54 drives the stacking rod 53 to move up and down, so as to realize the lifting of the pallet and stack multiple pallets.

[0026] Guide rods 55 are arranged on the moving frame 54 along its width direction. Two stacking rods 53 are slidably arranged on the guide rods 55 to approach or move away from each other. When it is necessary to clamp the pallet, the two stacking rods 53 approach each other to clamp the pallet, and then driven by the moving frame 54, the pallet is driven to move upward, waiting for another pallet to move to the lower part of this pallet. When another pallet moves into place, the moving frame 54 moves downward, places the pallet clamped by the stacking rods 53 on the other pallet below, and then the two stacking rods 53 move away from each other and clamp on both sides of the other pallet. The stacking of more pallets can repeat the foregoing operations to realize the stacking of pallets.

[0027] In an embodiment, the moving frame 54 and the stacking rod 53 can be driven by a cylinder 56. For example, as Figure 4 shown, the moving frame 54 realizes up-and-down movement through a first cylinder 56 arranged on the gantry 52. The stacking rod 53 realizes approaching or moving away from each other through a second cylinder 57 arranged on the moving frame 54.

[0028] Preferably, clamping plates 531 are arranged at intervals on the side of the stacking rod 53 close to the stacking roller path 51. The clamping plates 531 extend towards the stacking roller path 51. When the stacking rod 53 clamps the pallet, the clamping plates 531 can be inserted into the socket of the pallet and abutted against the inner wall of the pallet to prevent the pallet from falling off between the two stacking rods 53 during the lifting process.

[0029] In an embodiment, the receiving mechanism 2 includes: a receiving roller path 21 and a first blocking plate 22. The receiving roller path 21 is inclined and arranged on one side of the injection molding machine 1. The pallet can be conveyed along the receiving roller path 21 to the shearing mechanism 4. For example, one end of the receiving roller path 21 close to the injection molding machine 1 is higher than its end close to the shearing mechanism 4. After the pallet is placed on the receiving roller path 21, it can slide to the shearing mechanism 4 by relying on its own gravity. The first blocking plate 22 is arranged at the end of the receiving roller path 21 to control the frequency of the pallet entering the shearing mechanism 4 and avoid excessive impact when the pallet slides from the receiving roller path 21 to the shearing mechanism 4, causing damage to itself and the shearing mechanism 4.

[0030] Preferably, the first baffle 22 can move up and down relative to the material receiving roller path 21 to block the tray from entering the material cutting mechanism 4. For example, when the tray is placed in front of the material receiving roller path 21, the first baffle 22 moves upward relative to the material receiving roller path 21 and protrudes above the upper surface of the material receiving roller path 21. The tray slides downward from the top of the material receiving roller path 21 to the end of the material receiving roller path 21 and is blocked by the first baffle 22. Then, the first baffle 22 descends below the upper surface of the material receiving roller path 21, and the tray can enter the material cutting mechanism 4 through it.

[0031] The first baffle 22 can be driven to move up and down, for example, by a cylinder or the like, which is a conventional means in the art and will not be elaborated here.

[0032] There are many gates that need to be removed on the trays produced by injection molding. The material cutting mechanism 4 of the automatic production line for the trays of the present invention can effectively remove the gates on the trays. As Figure 2 shown, the material cutting mechanism 4 includes: a material cutting roller path 41, a material cutting head 42, and a carrying bracket 43. The material cutting roller path 41 is used to carry and convey the trays. One end of the material cutting roller path 41 is connected to the material receiving roller path 21, and the other end is connected to the stacking roller path 51, thereby realizing the transfer of the trays between various mechanisms. The material cutting head 42 is arranged above the material cutting roller path 41 and is used to cut off the gates on the trays. The carrying bracket 43 is arranged above the material cutting roller path 41, and the material cutting head 42 is movably arranged on the carrying bracket 43. For example, the carrying bracket 43 can include two support rods perpendicular to each other, and the two support rods can slide relative to each other. The material cutting head 42 slides on one of the support rods, thereby realizing the movement on the tray to cut off multiple gates on the surface of the tray.

[0033] Furthermore, the material cutting mechanism 4 further includes a waste recycling pipe fitting 45, which is connected to the material cutting head 42 through a hose (the hose is not shown in the figure) and is used to discharge the cut-off gates. For example, after the material cutting head 42 cuts off the gate and sends it into the hose, the waste recycling pipe fitting 45 uses a suction machine to suck away the cut-off gate through the hose and discharge it to a designated waste recycling place, avoiding the interference of the trimmed gates on the production line.

[0034] Preferably, a liftable second baffle 44 is arranged on the material cutting roller path 41 to block the tray from entering the stacking mechanism 5. For example, when the tray is on the material cutting roller path 41, the second baffle 44 rises and protrudes above the upper surface of the material cutting roller path 41 to block the tray and prevent it from entering the stacking roller path 51. After the material cutting head 42 cuts off the gates on the tray, the second baffle 44 descends below the upper surface of the material cutting roller path 41, and the tray enters the stacking roller path 51 along the material cutting roller path 41. The second baffle 44 can be driven to move up and down, for example, by a cylinder or the like, which is a conventional means in the art and will not be elaborated here.

[0035] In one embodiment, the automated production line of the tray may further be provided with a laser coding machine 6 for printing relevant information on the tray. Preferably, the laser coding machine 6 is arranged on the side of the trimming roller path 41. Since the time for sprue trimming is relatively longer than that of other steps and laser coding also requires a certain amount of time, arranging the laser coding machine 6 on the side of the trimming roller path 41 can utilize the time for sprue trimming to perform coding, thereby improving the overall efficiency of tray production.

[0036] It can be understood that the injection molding machine 1, the material receiving mechanism 2, the material picking robotic arm 3, the trimming mechanism 4, and the stacking mechanism 5 can be equipped with control devices for operation control and can be coordinated with a variety of sensors to achieve production operations such as the connection of processes and the positioning of trays, which will not be elaborated here.

[0037] In summary, the automated production line of the tray of the present invention realizes the automated production of trays by integrating the material receiving mechanism 2, the material picking robotic arm 3, the trimming mechanism 4, and the stacking mechanism 5, without manual intervention, thereby improving the production efficiency of the entire production line. The stacking mechanism 5 can achieve automatic stacking of trays by setting stacking rods 53. Compared with using a robotic arm to stack trays, the stacking mechanism 5 has better accuracy and the stacked trays are not easily offset.
