Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to an automatic empty material tray recycling mechanism. Background Technology

[0002] Existing automated production lines generally use trays to carry and transfer parts. After production is completed, a large number of empty trays need to be collected and reused. Traditional empty tray recycling mechanisms mostly use basic conveying and stacking methods, lacking precise control over the empty trays before they enter the stacking area.

[0003] In actual operation, when the empty material tray reaches the recycling area via the conveyor belt, due to factors such as running inertia, braking error or the dimensional tolerance of the empty tray itself, a certain lateral positional offset often occurs, that is, the empty tray fails to be precisely centered.

[0004] This positional offset makes it highly susceptible to interference and jamming with the inner wall, guide rails, or stacking mechanism of the collection bin when the empty tray is pushed or lifted into it. Once jamming occurs, the recycling mechanism will stop operating, severely affecting the automation efficiency and stable operation of the entire production line, becoming a key technical bottleneck that urgently needs to be solved in the automatic empty tray recycling mechanism.

[0005] Therefore, this utility model proposes an automatic empty tray recycling mechanism to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the automatic empty tray recycling mechanism, such as the empty tray may be misaligned at the end of the conveying process, jamming during recycling, and lack of effective buffering and blocking mechanisms during stacking, this utility model aims to provide an automatic empty tray recycling mechanism with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an automatic empty material tray recycling mechanism, including: a tray collection bin, a conveyor belt fixedly connected to one side of the tray collection bin, an installation plate supported and connected to the bottom of the conveyor belt by a connecting column, a lifting and blocking mechanism disposed at the bottom of the tray collection bin, and multiple stacking locking mechanisms fixedly connected to the inner walls on both sides of the tray collection bin.

[0008] The mounting plate is equipped with a clamping positioning mechanism on its top. The clamping positioning mechanism includes: a drive motor, a rotating plate, two pull rods, two clamps, two slide rails, and two sliders.

[0009] The output end of the drive motor is fixedly connected to the center of the rotating plate, and one end of two pull rods is rotatably connected to the edge of the rotating plate. The other ends of the two pull rods are rotatably connected to corresponding clamps. The bottom of the clamps is slidably engaged with two slide rails on the top of the mounting plate via sliders, so that the drive motor drives the clamps to reciprocate synchronously along the slide rails. This linkage combination structure of rotating plate-pull rod-slide rail can accurately adjust the empty material tray to the center position, which is the core structure for achieving precise positioning in this solution.

[0010] Preferably, the lifting and blocking mechanism includes a cylinder and an L-shaped plate. The cylinder is fixedly disposed at the bottom of the inner part of the collection bin, and the output end of the cylinder is fixedly connected to the L-shaped plate. During the lifting process, the vertical surface of the L-shaped plate simultaneously blocks the front side of the conveyor belt, realizing the integrated function of lifting and blocking.

[0011] Preferably, the stacking locking mechanism includes a mounting shell, a spring, a guide post, a limiting plate, and a receiving block. The mounting shell is fixedly connected to the inside of the side wall of the tray storage compartment. The limiting plate is slidably disposed inside the mounting shell. The spring is disposed inside the mounting shell and abuts against the limiting plate. The receiving block is fixedly connected to the side of the limiting plate away from the spring and extends through the mounting shell into the inside of the tray storage compartment.

[0012] Preferably, the spring is sleeved on the outside of the guide post, and the guide post is fixedly connected to the side of the limiting plate near the spring, providing stable sliding guidance for the spring and the limiting plate.

[0013] Preferably, the middle position of the pull rod is rotatably connected to both sides of the mounting plate, one end of the pull rod is connected to the rotating plate, and the other end of the pull rod is connected to the clamp, which further ensures the stability of the synchronous movement of the clamp.

[0014] Preferably, the front and rear sides of the tray collection compartment are fixedly connected with abutment plates to limit the forward and backward movement range of the empty trays.

[0015] Preferably, the rotating plate is rotatably disposed on the top of the mounting plate and located between the two slide rails. This arrangement is beneficial to the symmetry of the power transmission of the drive motor.

[0016] Preferably, there are four connecting columns, and the bottom of each connecting column is fixedly connected to the mounting plate, ensuring the stability of the entire positioning mechanism base platform.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting up a synchronous clamping and positioning mechanism composed of a drive motor, a rotating plate, a pull rod, a slider and a slide rail, the precise centering positioning of the empty material tray is achieved, which solves the problem of the empty tray conveying end position offset in the prior art, which easily leads to jamming or poor recycling, and improves the stability and automation of recycling.

[0018] 2. In this utility model, by setting an L-shaped plate driven by a cylinder, the L-shaped plate has the functions of lifting and bearing and physical blocking, which solves the problem that the recycling mechanism in the prior art cannot effectively block the interference of subsequent incoming materials when transferring empty discs, making the transfer process of empty discs safer and more reliable, and avoiding collisions and blockages.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figures 1 to 4 This utility model provides an automatic empty tray recycling mechanism, which aims to solve the problems in the prior art where the empty tray may be misaligned at the end of the conveying process, resulting in jamming or poor recycling, as well as the lack of an effective buffering and blocking mechanism.

[0022] like Figure 1 and Figure 2 As shown, the automatic empty tray recycling mechanism includes a tray collection bin 1 and a conveyor belt 2 fixedly connected to one side of the tray collection bin 1. The tray collection bin 1 serves as the core carrier for recycling empty trays 3, while the conveyor belt 2 serves as the main conveying channel for the empty trays 3. The bottom of the conveyor belt 2 is supported by four connecting columns 6 and connected to a mounting plate 5.

[0023] A clamping positioning mechanism is provided on the top of the mounting plate 5. This mechanism is the core component for achieving precise centering of the empty disk. It includes a drive motor 11, a rotating plate 10, two pull rods 12, two clamps 9, two slide rails 7, and two sliders 8. The output end of the drive motor 11 is fixedly connected to the center of the rotating plate 10. The rotating plate 10 is rotatably positioned on the top of the mounting plate 5 and located between the two slide rails 7. The rotation of the rotating plate 10 is the power input for the synchronous movement of the clamps 9. The edge of the rotating plate 10 is rotatably connected to one end of the two pull rods 12, and the other end of the pull rods 12 is rotatably connected to the corresponding clamps 9. The bottom of the clamps 9 is fixedly connected to the sliders 8, which slide in contact with the slide rails 7 on the top of the mounting plate 5. This converts the rotational motion of the rotating plate 10 into the reciprocating synchronous linear movement of the clamps 9 along the slide rails 7, achieving stable clamping and positioning of the empty disk 3. The middle positions of the pull rods 12 are rotatably connected to both sides of the mounting plate 5, further stabilizing the movement trajectory of the pull rods 12.

[0024] The bottom of the tray collection compartment 1 is equipped with a lifting and blocking mechanism. This mechanism is used to vertically send an empty tray 3 into the tray collection compartment 1 after it has been positioned, and temporarily block the entry of subsequent empty trays 3 to prevent interference. Multiple stacking locking mechanisms are fixedly connected to the inner walls of both sides of the tray collection compartment 1. These mechanisms provide elastic cushioning and automatic stacking support for the entering empty trays 3. In addition, abutment plates 4 are fixedly connected to the front and rear sides of the tray collection compartment 1 to limit the forward and backward movement range of the empty trays 3.

[0025] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the automatic empty material tray recycling mechanism also includes a lifting and blocking mechanism, and the lifting and blocking mechanism forms a specific structural cooperation and connection relationship with the collection tray 1.

[0026] Please refer to the following carefully. Figure 2 and Figure 4The core structure is described in detail below: The lifting and blocking mechanism includes a cylinder 18 and an L-shaped plate 19. The cylinder 18 is fixedly installed at the bottom of the tray collection compartment 1, and its function is to provide vertical lifting power. The output end of the cylinder 18 is fixedly connected to the L-shaped plate 19. The L-shaped plate 19 has a horizontal surface and a vertical surface. The horizontal surface is used to support the positioned empty tray 3 and lifts the empty tray 3 upward by extending the cylinder 18. The vertical surface simultaneously blocks the front side of the conveyor belt 2 during the upward movement of the L-shaped plate 19, achieving physical blocking and ensuring that subsequent empty trays will not enter the positioning area and cause interference during the transfer of the empty tray 3.

[0027] Meanwhile, this system is also equipped with multiple stacking locking mechanisms, which are used to buffer and stably receive empty disk 3 after it enters the collection bin 1. Please refer to... Figure 2 and Figure 3 The stacking locking mechanism includes a mounting shell 13, a spring 14, a guide post 15, a limiting plate 16, and a receiving block 17. The mounting shell 13 is fixedly connected to the inner walls of both sides of the tray compartment 1, serving as a mounting carrier for the internal components. The spring 14 is disposed inside the mounting shell 13, with one end abutting against the limiting plate 16. The limiting plate 16 is slidably disposed inside the mounting shell 13 to withstand impact forces and compression. The spring 14 is sleeved on the outer side of the guide post 15, which is fixedly connected to the side of the limiting plate 16 near the spring 14. The function of the guide post 15 is to provide precise sliding guidance for the spring 14 and the limiting plate 16, preventing displacement. The receiving block 17 is fixedly connected to the side of the limiting plate 16 away from the spring 14 and extends through the mounting shell 13 into the inside of the tray hopper 1. The receiving block 17 has a sloping structure. When the empty tray 3 moves upward, its edge squeezes the receiving block 17, causing it to retract inward and compress the spring 14, thus achieving a buffering effect. After the empty tray 3 has completely passed through, the spring 14 pops out the receiving block 17, thereby automatically locking and receiving the empty tray 3 to complete the stacking. This spring-receiving block cooperation structure ensures that the empty tray 3 is effectively protected when entering the hopper and achieves self-locking stacking.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, the L-shaped plate 19 in the lifting and blocking mechanism has a horizontal surface for supporting the empty tray 3. The vertical surface of the L-shaped plate 19 is simultaneously blocked on the front side of the conveyor belt 2 during the process of the cylinder 18 driving the empty tray upward. This L-shaped plate structure ensures that during the single recycling and transfer of the empty tray 3, subsequent empty trays will not enter the positioning area and cause interference, thus ensuring the stability and reliability of the transfer process.

[0029] In another preferred embodiment, the stacking locking mechanism includes a mounting shell 13, a spring 14, a guide post 15, a limiting plate 16, and a receiving block 17. The mounting shell 13 is fixedly connected to the inside of the side wall of the tray collection compartment 1. The limiting plate 16 is slidably disposed inside the mounting shell 13. The spring 14 is disposed inside the mounting shell 13, with one end of the spring 14 abutting against the limiting plate 16. The receiving block 17 is fixedly connected to the side of the limiting plate 16 away from the spring 14 and extends through the mounting shell 13 into the inside of the tray collection compartment 1. The elastic deformation of the spring 14 buffers the impact force on the empty tray 3, and the receiving block 17 stably supports and stacks the empty tray 3.

[0030] As another preferred embodiment, in order to provide precise sliding guidance for the spring 14 and the limiting plate 16, the spring 14 is sleeved on the outside of the guide post 15, and the guide post 15 is fixedly connected to the side of the limiting plate 16 near the spring 14. The guide post 15 effectively prevents the limiting plate 16 from deviating or getting stuck when it slides under force, ensuring the reliable operation of the buffer and locking mechanism.

[0031] As another preferred embodiment, in order to achieve synchronous and stable movement of the clamps 9, the two sides of the mounting plate 5 are rotatably connected to the middle position of the pull rod 12. One end of the pull rod 12 is connected to the rotating plate 10, and the other end of the pull rod 12 is connected to the clamps 9. This connection method, through the rotation of the rotating plate 10, makes the pull rods 12 on both sides and the clamps 9 form geometric constraints, ensuring the synchronous relative movement of the two clamps 9.

[0032] As another preferred embodiment, the front and rear sides of the collection tray 1 are fixedly connected with abutment plates 4. The abutment plates 4 are located at both ends of the conveying path of the empty tray 3 and are used to limit the forward and backward movement range of the empty tray 3. Together with the clamp positioning mechanism, the empty tray can be accurately positioned in three-dimensional space.

[0033] In another preferred embodiment, the rotating plate 10 is rotatably disposed on the top of the mounting plate 5 and located between the two slide rails 7. This central arrangement allows the power of the drive motor 11 to be transmitted evenly and symmetrically to the pull rods 12 on both sides, which is the key layout for realizing the synchronous movement of the clamps 9 on both sides.

[0034] In another preferred embodiment, the bottom of the conveyor belt 2 is supported and connected to the mounting plate 5 by four connecting columns 6. The four connecting columns 6 provide stable four-point support for the mounting plate 5, ensuring the stability of the entire clamp positioning mechanism and the basic platform of the conveyor belt 2.

[0035] Working principle: When empty disk 3 needs to be retrieved, the conveyor belt 2 transports the empty disk 3 to the designated positioning area located below the disk collection bin 1.

[0036] The drive motor 11 starts and drives the rotating plate 10, which is fixedly connected to its output end, to rotate. The rotation of the rotating plate 10 causes two pull rods 12 connected to its edge to pull the two clamps 9 to move synchronously relative to each other along the slide rail 7. Since the bottom of the clamps 9 is slidably engaged with the slide rail 7 by the slider 8, this synchronous movement ensures that the force exerted by the clamps 9 on the empty plate 3 is uniform and symmetrical, accurately adjusting the empty plate 3 to the center position and effectively avoiding jamming problems caused by the offset of the empty plate 3.

[0037] After the empty tray 3 is positioned, the L-shaped plate 19 below it is ready to receive the empty tray 3. When the cylinder 18 is started, its output end drives the fixedly connected L-shaped plate 19 to rise upward, transporting the empty tray 3 to the designated height inside the tray collection bin 1. At the same time, the vertical surface of the L-shaped plate 19 simultaneously blocks the front side of the conveyor belt 2, preventing subsequent empty trays 3 from entering the positioning area, ensuring that the current transfer process is not disturbed.

[0038] During the lifting process, the empty tray 3 will come into contact with and apply pressure to the receiving blocks 17 on both sides of the inner wall of the tray collection compartment 1. After the receiving blocks 17 are subjected to force, they push the fixedly connected limiting plate 16 to slide along the inside of the mounting shell 13, compressing the spring 14 behind it. The elastic deformation of the spring 14 converts the impact force of the empty tray 3 into elastic potential energy, achieving a buffering effect and preventing the empty tray 3 from being damaged by hard contact with the compartment body. When the empty tray 3 has completely passed the height of the receiving blocks 17, the spring 14 gradually returns to its original position and pushes the limiting plate 16 and the receiving blocks 17 back into their original positions, so that the receiving blocks 17 extending into the tray collection compartment 1 always maintain stable support for the empty tray 3, completing the automatic stacking.

[0039] After the empty tray 3 is stably received, the cylinder 18 drives the L-shaped plate 19 to return downward and disengage from the empty tray 3. At the same time, the vertical surface of the L-shaped plate 19 leaves the front side of the conveyor belt 2, and the mechanism completes the cycle. After the next empty tray 3 enters the positioning area, the above process is repeated.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
