Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to an automatic tray changing machine. Background Technology

[0002] An automatic tray changer is a specialized mechanical device used to automatically exchange empty and full trays, aiming to improve the automation level of material turnover on the production line. However, a significant portion of existing automatic tray changers on the market currently have overly simplistic overall structural designs and low functional integration, resulting in noticeable process breaks during task execution. These devices often fail to smoothly and seamlessly complete a series of key automated actions, including the automatic feeding and precise positioning of empty trays, the rotation and collection of trays at the workstation, and the final stacking and storage of full-loaded trays. Because these processes rely on manual intervention or involve pauses, they not only reduce the overall efficiency of the production line but also limit the flexibility and reliability of the equipment. Therefore, their low overall automation level is a prominent issue, making it difficult to meet the stringent requirements of modern intelligent manufacturing workshops for high-efficiency and continuous production, necessitating a comprehensive upgrade through mechanical structure optimization. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides an automatic tray changing machine, the specific technical solution of which is as follows: An automatic tray changing machine includes a frame, a belt conveyor, a tray rotation mechanism, an empty tray stacking mechanism, a tray rotation and repositioning mechanism, a tray temporary placement platform, a tray pushing mechanism, and a full tray stacking mechanism. The belt conveyor and tray rotation mechanism are installed at the front of the frame. The belt conveyor drives the belt to the tray rotation mechanism, which in turn drives the tray to rotate and rewind the belt. The empty tray stacking mechanism is installed above the frame, where multiple empty trays are stacked. The tray rotation and repositioning mechanism and the tray temporary placement platform are installed inside the frame. The tray rotation and repositioning mechanism is located below the empty tray stacking mechanism, and the tray temporary placement platform is also located below it. The tray rotation and repositioning mechanism drives the trays from the empty tray stacking mechanism to sequentially enter the tray rotation mechanism and the tray temporary placement platform. The tray pushing mechanism pushes the trays from the tray temporary placement platform to the full tray stacking mechanism.

[0004] As a preferred embodiment of this utility model, the empty material tray stacking mechanism includes a limiting plate, a bearing cylinder, and a bearing plate. There are multiple limiting plates installed above the frame, and the multiple limiting plates surround to form a material tray receiving area. An empty groove is provided above the frame, and multiple bearing cylinders are installed on the side of the empty groove. The piston rod of the bearing cylinder is connected to the bearing plate, and the bearing plate extends into the material tray receiving area to carry the empty material tray.

[0005] As a preferred embodiment of this utility model, the material tray rotation and repositioning mechanism includes a rotary power mechanism, a large turntable, a material tray clamping mechanism, a slide rail assembly, a shaft core, a limit bearing, a fixed clamping plate, and a pushing mechanism. The rotary power mechanism drives the large turntable to rotate. The large turntable is slidably mounted with the material tray clamping mechanism via the slide rail assembly. There are multiple material tray clamping mechanisms distributed circumferentially around the central axis of the large turntable. The center of the large turntable is rotatably connected to the center of the fixed clamping plate via the shaft core. A bearing is fitted between the shaft core and the fixed clamping plate, allowing relative rotation between the large turntable and the fixed clamping plate. A limit bearing is installed at the inner end of the material tray clamping mechanism. The fixed clamping plate has a limit groove and an ejection groove. The limit bearing is located in the limit groove, and the limit groove communicates with the ejection groove. When the material tray clamping mechanism rotates to the position where the limit bearing faces the ejection groove, the pushing mechanism drives the material tray clamping mechanism to move along the slide rail assembly closer to the material tray.

[0006] As a preferred embodiment of this utility model, the material tray clamping mechanism includes a movable seat, a bushing, a petal-shaped air shaft, a push rod, a small bearing, a bushing, a connecting sleeve, and an opening and closing power component. A limiting bearing is installed at the end of the movable seat, a bushing is installed in front of the movable seat, and a petal-shaped air shaft is installed in front of the bushing. The bushing contains two small bearings, and the bushing is located between the two small bearings. The rear end of the connecting sleeve is fitted inside the small bearings, and the front end of the connecting sleeve is connected to the petal-shaped air shaft. The outer circumference of the petal-shaped air shaft is provided with multiple dividing grooves, which are circumferentially distributed around the central axis of the petal-shaped air shaft. A push rod is movably installed inside the petal-shaped air shaft. The opening and closing power component drives the push rod to move back and forth. The opening and closing power component is a cylinder. The front end of the push rod has a tapered surface. The push rod drives the petal-shaped air shaft to expand and clamp the center of the material tray.

[0007] As a preferred embodiment of this utility model, the pushing mechanism includes a fixed base, a longitudinal pushing cylinder, a longitudinal pushing block, a longitudinal limiting cylinder, a longitudinal limiting head, a transverse pushing cylinder, and a transverse pushing block. The longitudinal pushing cylinder is installed on the side of the fixed base. The longitudinal pushing cylinder drives the longitudinal pushing block to push the material tray clamping mechanism to move longitudinally. The longitudinal limiting cylinder drives the longitudinal limiting head to move longitudinally. The longitudinal limiting head is lower than the longitudinal pushing block by one material tray height. The transverse pushing cylinder is installed at the fixed base. The transverse pushing cylinder drives the transverse pushing block to push the material tray clamping mechanism to move transversely. The longitudinal pushing block moves away from the fixed clamping plate, and the transverse pushing block can move into or out of the fixed clamping plate.

[0008] As a preferred embodiment of this utility model, the material tray temporary placement platform is lower than the material tray rotation mechanism, the material tray pushing mechanism includes a material tray pushing cylinder and a push plate, and the full material tray stacking mechanism is located in front of the material tray temporary placement platform. The material tray pushing cylinder drives the push plate to move so that the material tray on the material tray temporary placement platform is transferred to the full material tray stacking mechanism.

[0009] As a preferred embodiment of this utility model, the full-load tray stacking mechanism includes a lifting platform and a servo lifting mechanism. The lifting platform is located in front of the tray temporary placement platform, and the servo lifting mechanism drives the lifting platform to move up and down.

[0010] Beneficial effects: When this utility model of automatic tray changing machine is working, multiple empty trays are stacked in the empty tray stacking mechanism. The tray rotation and repositioning mechanism drives the trays in the empty tray stacking mechanism to rotate and enter the tray rotation mechanism in front. The material belt conveying mechanism drives the material belt to the tray rotation mechanism. The tray rotation mechanism drives the tray to rotate and wind up the material belt. After the tray is full of material belt, the tray rotation and repositioning mechanism drives the tray to rotate and enter the tray temporary placement platform. The tray pushing mechanism pushes the tray on the tray temporary placement platform to transfer it to the full tray stacking mechanism. The above actions are repeated to complete the collection of multiple trays. The process is seamlessly connected, with a high degree of automation, which significantly improves production efficiency and meets actual needs. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] like Figure 1 and 2 As shown, an automatic tray changing machine includes a frame 1, a belt conveying mechanism 2, a tray rotating mechanism 3, an empty tray stacking mechanism 4, a tray rotation and repositioning mechanism 5, a tray temporary placement platform 6, a tray pushing mechanism 7, and a full tray stacking mechanism 8. The belt conveying mechanism 2 and the tray rotating mechanism 3 are installed at the front of the frame 1. These are common mechanisms in tray changing machines. The belt conveying mechanism 2 drives the belt to the tray rotating mechanism 3, and the tray rotating mechanism 3 drives the tray to rotate and rewind the belt. The machine is mounted on top of the frame 1. An empty material tray stacking mechanism 4 is installed, in which multiple empty material trays are stacked. Inside the frame 1, a material tray rotation and transfer mechanism 5 and a material tray temporary platform 6 are installed. The material tray rotation and transfer mechanism 5 is located below the empty material tray stacking mechanism 4, and the material tray temporary platform 6 is located below the material tray rotation and transfer mechanism 5. The material tray rotation and transfer mechanism 5 drives the material trays of the empty material tray stacking mechanism 4 to enter the material tray rotation mechanism 3 and the material tray temporary platform 6 in sequence. The material tray pushing mechanism 2 pushes the material trays on the material tray temporary platform 6 to transfer them to the full material tray stacking mechanism 8.

[0016] like Figure 3As shown, the empty material tray stacking mechanism 4 includes a limiting plate 41, a bearing cylinder 42, and a bearing plate 43. There are multiple limiting plates 41 installed above the frame 1. The multiple limiting plates 41 surround to form a material tray receiving area. An empty groove 1a is provided above the frame 1. Multiple bearing cylinders 42 are installed on the side of the empty groove 1a. The piston rod of the bearing cylinder 32 is connected to the bearing plate 43. The bearing plate 43 extends into the material tray receiving area to carry the empty material trays. Multiple empty material trays are stacked in the material tray receiving area. The bottom material tray is carried by the bearing plate 43. After the material tray clamping mechanism clamps the material tray, the bearing cylinder 42 drives the bearing plate 43 to retract, and the bottom material tray can be detached from the empty groove 1a.

[0017] like Figure 4 and 5 As shown, the material tray rotation and repositioning mechanism 5 includes a rotary power mechanism 51, a large turntable 52, a material tray clamping mechanism 53, a slide rail assembly 54, a shaft core 55, a limit bearing 56, a fixed clamping plate 57, and a pushing mechanism 58. The rotary power mechanism 51 drives the large turntable 52 to rotate. The large turntable 52 is slidably mounted with the material tray clamping mechanism 53 via the slide rail assembly 54. The slide rail assembly 54 consists of common slide rails and sliders. There are multiple material tray clamping mechanisms 53, which are distributed circumferentially around the central axis of the large turntable 52. The center of the large turntable 52 is rotatably connected to the center of the fixed clamping plate 57 via the shaft core 55. A bearing is fitted between the shaft core 55 and the fixed clamping plate 57, so that the large turntable 52 and the fixed clamping plate 57 can be... When relative rotation occurs, the large turntable 52 will not cause the fixed clamping plate 57 to rotate. The inner end of the material tray clamping mechanism 53 is equipped with a limit bearing 56. The fixed clamping plate 57 is provided with a limit circular groove 571 and an ejection groove 572. The limit bearing 56 is located in the limit circular groove 571 and can limit the position of the material tray clamping mechanism 53. The limit circular groove 571 communicates with the ejection groove 572. When the material tray clamping mechanism 53 rotates to the position where the limit bearing 56 faces the ejection groove 572, the pushing mechanism 58 drives the material tray clamping mechanism 53 to move along the slide rail assembly 54 and approach the material tray. In this embodiment, the material tray clamping mechanism 53 has 4 positions that can transfer the material tray to the empty material tray, the loading material tray, the full material tray, the empty station, etc.

[0018] The rotary power mechanism 51 includes a motor, a synchronous belt drive assembly, a rotary shaft, and a flange shaft. The motor drives the rotary shaft to rotate through the synchronous belt drive assembly, which consists of a common synchronous belt and a synchronous pulley. The rotary shaft is fixedly connected to the axis of the large turntable 52 through the flange shaft. When the rotary shaft rotates, it will drive the large turntable 52 to rotate.

[0019] like Figure 6 and 7As shown, the material tray clamping mechanism 53 includes a movable seat 531, a bushing 532, a petal-shaped air shaft 533, a push rod 534, and an opening and closing power component 535. A limit bearing 56 is installed at the end of the movable seat 531, and a bushing 532 is installed in front of the movable seat 531. A petal-shaped air shaft 533 is installed in front of the bushing 532. The petal-shaped air shaft 533 has multiple partition grooves on its outer periphery, which are circumferentially distributed around the central axis of the petal-shaped air shaft 533. The push rod 534 is movably mounted inside the petal-shaped air shaft 533. The opening and closing power component 535 drives the push rod to move back and forth. The opening and closing power component is a cylinder. The front end of the push rod 534 has a tapered surface. The push rod 534 drives the petal-shaped air shaft 533 to expand and clamp the center of the material tray. In addition, the tray clamping mechanism includes a small bearing 536, a bushing 537, and a connecting sleeve 538. The small bearing 536 and bushing 537 are housed inside the bushing 532. There are two small bearings, and the bushing is located between the two small bearings. The rear end of the connecting sleeve 538 is fitted inside the small bearing 536, and the front end of the connecting sleeve 538 is connected to the petal-shaped air shaft 533. The petal-shaped air shaft 533 has an expansion hole 533a at its center. The inner diameter of the expansion hole 533a is smaller than the outer diameter of the push rod 534. The push rod 534 extends into the expansion hole 533a, causing the petal-shaped air shaft to expand and thus clamp the tray. The opening and closing power component 535 drives the push rod to move backward to reset, thereby removing the tray. The mechanical drive structure is stable and reliable.

[0020] like Figure 8 and 9 As shown, the pushing mechanism 58 includes a fixed base 581, a longitudinal pushing cylinder 582, a longitudinal pushing block 583, a longitudinal limiting cylinder 584, a longitudinal limiting head 585, a transverse pushing cylinder 586, and a transverse pushing block 587. The fixed base 581 can be fixedly installed on the machine frame via a connecting rod. The longitudinal pushing cylinder 582 is installed on the side of the fixed base 581. The longitudinal pushing cylinder 582 drives the longitudinal pushing block 583 to push the material tray clamping mechanism to move longitudinally. The longitudinal limiting cylinder 584 drives the longitudinal limiting head to move longitudinally. The longitudinal limiting head 585 is lower than the longitudinal pushing block by one tray height. When taking trays stacked together from above, one tray can be taken to prevent the trays on the upper layer from falling. A transverse pushing cylinder 586 is installed at the fixed base 581. The transverse pushing cylinder 586 drives the transverse pushing block to push the tray clamping mechanism to move laterally. The longitudinal pushing block moves away from the fixed clamping plate 57. The transverse pushing block can move into or out of the fixed clamping plate 57. The longitudinal pushing block can be used to push and take empty trays. The transverse pushing block can be used to push and take trays that are full of material.

[0021] like Figure 10As shown, the material tray temporary placement platform 6 is lower than the material tray rotation mechanism 3 to ensure that the material tray rotation and transfer mechanism 5 will not interfere with the rotation of the material tray. The material tray pushing mechanism 7 includes a material tray pushing cylinder and a push plate. The full material tray stacking mechanism 8 is located in front of the material tray temporary placement platform 6. The material tray pushing cylinder drives the push plate to move, so that the material tray on the material tray temporary placement platform moves forward and is transferred to the full material tray stacking mechanism 8. In addition, the full material tray stacking mechanism 8 includes a lifting platform 81 and a servo lifting mechanism 82. The lifting platform 81 is located in front of the material tray temporary placement platform 6. The servo lifting mechanism drives the lifting platform to move up and down, so that multiple material trays are stacked together.

[0022] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be considered that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the protection scope of the present utility model.
