Description

Technical Field

[0001] This utility model belongs to the field of encoder machines, specifically relating to a belt-type encoder machine. Background Technology

[0002] In the modern manufacturing environment, the efficiency of the production line is directly related to the competitiveness and profitability of enterprises. With the increasing demands for product quality and the growing demand for personalized customization in the global market, manufacturing enterprises face the dual pressure of ensuring mass production while also taking into account small-batch diversified production.

[0003] Currently, traditional factories still rely heavily on workers to manually handle and arrange products. This not only increases labor costs but is also susceptible to human factors such as fatigue and negligence, leading to higher error rates. Furthermore, while some factories use semi-automated equipment that can reduce labor intensity to some extent, it often requires additional adjustments when handling products of different shapes, sizes, or weights, limiting its application. Therefore, these methods suffer from inefficiency, lack of flexibility, and susceptibility to human error. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a belt-type palletizer that can realize the automated handling and arrangement of different types of products, significantly improve work efficiency and ensure product quality.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a belt-type palletizer for placing several products processed by external equipment into a pallet in sequence, including: a frame on which a conveyor belt is configured;

[0006] The machine includes a gripping mechanism and a lifting mechanism. The gripping mechanism is mounted on the frame and located above the conveyor belt. The movable end of the gripping mechanism is connected to a gripper and a magnetic block with a height difference. The gripping mechanism can drive the gripper and the magnetic block to flip and change position so that they can grip or attract products of different shapes when they extend out of the frame. The lifting mechanism is located at the end of the conveyor belt and can be lifted vertically to support the products on the gripper or the magnetic block.

[0007] A positioning mechanism and a pushing mechanism are provided on the conveyor belt. The pushing mechanism is used to push the product on the lifting mechanism into the conveyor belt, and the positioning mechanism guides and restricts the product to the end of the conveyor belt away from the lifting mechanism.

[0008] A transfer mechanism is provided inside the frame, which is used to grab the products at the end of the conveyor belt and place them sequentially into the tray.

[0009] In the aforementioned belt-type stacking machine, the movable end of the gripping mechanism is connected to a bracket, the gripper is located on the top wall of the bracket, and a gripping groove for moving and adhering to the product is formed in the gripper; the magnetic blocks are symmetrically arranged on the bottom wall of the bracket, and there is a height difference between them and the conveyor belt.

[0010] In the aforementioned belt-type winding machine, the lifting mechanism includes a lifting cylinder and a lifting plate. The lifting cylinder is disposed at the end of the conveyor belt, and the lifting plate is connected to the output end of the lifting cylinder. A clearance slope is formed at the end of the lifting plate, and the clearance slope is movably close to the bend of the conveyor belt so that the top wall of the lifting plate is flush with the top wall of the conveyor belt.

[0011] In the aforementioned belt-type encoder, the gripping mechanism further includes:

[0012] A movable frame is movably mounted on the frame.

[0013] A first material transfer module is mounted on the movable frame, and a mounting bracket is connected to the movable end of the first material transfer module.

[0014] The drive unit and the rotating shaft are provided. The drive unit is mounted on the mounting bracket, which extends outward to form a mounting base. The rotating shaft is movably disposed within the mounting base, and a pneumatic finger is connected to one end of the rotating shaft. A bracket is connected to the pneumatic finger, and the other end of the rotating shaft is connected to the output end of the drive unit via a coupling.

[0015] In the above-mentioned belt-type stacking machine, the pushing mechanism includes a pushing cylinder and a pushing plate. The pushing cylinder is installed on the side wall of the conveyor belt, and the pushing plate is connected to the output end of the pushing cylinder, for pushing the product on the lifting plate into the conveyor belt.

[0016] In the aforementioned belt-type encoder, the positioning mechanism includes:

[0017] The guide member is connected to the movable frame, and the conveyor belt is rotatably mounted on the extended frame. The guide member and the conveyor belt together form a guide cavity, and the guide member can move relative to the extended frame to adjust the size of the guide cavity for the product to pass through.

[0018] A limiting block and a detector are disposed on the extension frame. The limiting block is located at the end of the guide cavity along its length and has an anti-detachment groove formed within it. The product in the guide cavity can be conveyed to the anti-detachment groove via the conveyor belt. The detector is used to detect the position of the product to give the transfer mechanism a signal to grasp the product.

[0019] In the above-mentioned belt-type encoder, the guide includes a first limiting plate and a second limiting plate. Both the first limiting plate and the second limiting plate have extension plates formed on them. The extension plates have waist-shaped holes. Fasteners are installed on the extension frame. The fasteners can pass through the waist-shaped holes and connect to the extension frame when the first limiting plate and the second limiting plate are close to or far apart.

[0020] In the aforementioned belt-type encoder, the transfer mechanism includes:

[0021] The second material transfer module is mounted on the frame;

[0022] The machine includes a lifting platform and a gripper. The lifting platform is connected to the movable end of the second material transfer module, and the gripper is connected to the lifting platform. The frame is also equipped with several feeding belts that hold the material trays. The gripper is used to grip the products in the anti-detachment groove and transfer them to the material tray.

[0023] In the aforementioned belt-type encoder, the side wall of the movable frame is provided with a guide rail along its length, and the frame is provided with a plurality of guide blocks along the horizontal direction, the guide rail being movably engaged with the guide blocks.

[0024] In the aforementioned belt-type palletizer, the movable frame is further provided with a fixed bracket, and an electronic scale located at the end of the conveyor belt is installed on the fixed bracket. The electronic scale is used to detect the weight of the product to be placed into the pallet.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The present invention provides a belt-type stacking machine that utilizes a flip-up gripping mechanism. This equipment can easily handle products of various shapes and materials without frequent tool changes or settings adjustments, thereby reducing production costs. Through the integrated design of lifting, positioning, pushing and transferring multiple functions, the time loss in intermediate links is reduced, the product turnover speed is accelerated, and the output rate of the entire production line is improved. This effectively avoids product damage caused by human factors and ensures the consistency of the quality of each finished product.

[0027] (2) By means of the movable snap-fit ​​between the guide block and the guide rail, the entire mobile frame and all its components can be retracted into the frame (i.e. away from external equipment), thus providing enough space for workers to change molds for external equipment. The overall structure is simple and the operation is convenient and quick.

[0028] (3) The design of the electronic scale further enables the weight detection of the products to be placed, ensuring that each product meets the required usage requirements and effectively guaranteeing the product qualification rate. Attached Figure Description

[0042] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0043] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. Example

[0044] like Figures 1 to 7 As shown, this utility model discloses a belt-type palletizing machine for sequentially placing several products processed by external equipment into a material tray 110. It includes: a frame 1 with a conveyor belt 10 mounted on it; a gripping mechanism 2 and a lifting mechanism 3. The gripping mechanism 2 is mounted on the frame 1 and located above the conveyor belt 10. The movable end of the gripping mechanism 2 is connected to a gripper 20 and a magnetic block 21 arranged at a height difference. The gripping mechanism 2 can drive the gripper 20 and the magnetic block 21 to flip and change positions, so that when they extend out of the frame 1, they can correspondingly grip or attract products of different shapes. The product is shaped like a claw; the lifting mechanism 3 is located at the end of the conveyor belt 10 and can be lifted vertically to carry the product on the gripper 20 or magnetic block 21; the positioning mechanism 4 and the pushing mechanism 5 are located on the conveyor belt 10. The pushing mechanism 5 is used to push the product on the lifting mechanism 3 into the conveyor belt 10, and the positioning mechanism 4 guides and restricts the product to the end of the conveyor belt 10 away from the lifting mechanism 3; the transfer mechanism 6 is located in the frame 1. The transfer mechanism 6 is used to grab the product at the end of the conveyor belt 10 and place it into the tray 110 in sequence.

[0045] In this solution, for processing external equipment, different shaped products can be manufactured by changing molds, such as cylindrical and convex / concave products. After the product processing in the external equipment is completed, before the gripping mechanism 2 extends the gripper 20 and magnetic block 21 out of the frame 1, appropriate adjustments need to be made according to the different types and shapes of the products. For example, when gripping a cylindrical product, simply adjust the gripper 20 to be below the magnetic block 21 to ensure that the gripper 20 directly and firmly grips the product; similarly, when dealing with convex / concave products... The magnetic block 21 flips to be below the gripper 20. When the gripping mechanism 2 drives the magnetic block 21 to extend out of the frame 1 and approach the equipment, the magnetic block 21 can be used to adsorb and grip the product, adapting to products of different shapes or materials (metal / non-metal). Because of this, the gripper 20 and magnetic block 21 with their height difference, along with the flipping and repositioning mechanism, allow the same equipment to handle multiple types of products without frequent tool changes, improving equipment versatility, reducing the risk of product damage, and effectively minimizing downtime for adjustments due to product type changes, maintaining continuous production line operation. As the lifting mechanism 3 moves vertically, the gripping mechanism 2 transfers the product above the lifting mechanism 3. Once the lifting mechanism 3 is flush with the surface of the conveyor belt 10, the pushing mechanism 5 smoothly pushes the product onto the conveyor belt 10. This process avoids direct placement of the product, preventing collisions and damage between the product and the conveyor belt 10. With the cooperation of the conveyor belt 10 and the positioning mechanism 4, each product can be accurately moved to the designated position so that the transfer mechanism 6 can quickly and accurately place the product into the tray 110 after grasping it, which greatly improves the overall efficiency of the production line. The fully automated design simplifies the operation process, reduces the degree of dependence on manual labor, effectively avoids product damage caused by human factors, and ensures the consistency of the quality of each finished product.

[0046] The movable end of the gripping mechanism 2 is connected to the bracket 22, the gripper 20 is located on the top wall of the bracket 22, and a gripping groove 200 for moving and sticking to the product is formed in the gripper 20; the magnetic block 21 is symmetrically arranged on the bottom wall of the bracket 22, and there is a height difference between it and the conveyor belt 10.

[0047] like Figure 2 and Figure 3As shown, when handling non-magnetic products or products unsuitable for magnetic adsorption, the gripping mechanism 2 flips to a position where the grippers 20 face downwards. At this point, the grippers 20 firmly hold the product through their internal clamping grooves 200, ensuring it won't slip during transport. The close fit design reduces the risk of product shaking or falling off during transport, ensuring operational safety and reliability; it also avoids surface damage caused by excessive pressure, maintaining the product's appearance quality. For metal or convex / concave products, this embodiment uses the strong magnetic force of the magnetic block 21 to firmly attract the product. The height difference ensures that the magnetic block 21 can be smoothly lifted after attracting the product without touching the conveyor belt 10 or other components. Therefore, the combined use of the magnetic block 21 and the grippers 20 allows the same palletizer to handle multiple types of products, enhancing its versatility and flexibility. It also allows for flexible switching between gripper 20 mode and magnetic attraction mode, effectively ensuring the overall efficiency of the production line. Preferably, in this embodiment, a rubber pad 201 can be detachably connected in the clamping groove 200, so as to further ensure that the quality of the gripped product is not damaged.

[0048] The lifting mechanism 3 includes a lifting cylinder 30 and a lifting plate 31. The lifting cylinder 30 is disposed at the end of the conveyor belt 10. The lifting plate 31 is connected to the output end of the lifting cylinder 30. A clearance slope 310 is formed at the end of the lifting plate 31. The clearance slope 310 is movably attached to the bend of the conveyor belt 10 so that the top wall of the lifting plate 31 is flush with the top wall of the conveyor belt 10.

[0049] like Figure 2 As shown, when the magnetic block 21 or gripper 20 grabs the product from the external device and moves it above the lifting plate 31, the lifting cylinder 30 can then drive the lifting plate 31 along... Figure 2 The lifting plate 31 moves vertically upwards. When it reaches the predetermined position (i.e., the lifting plate 31 lifts the product), the magnetic block 21 or gripper 20 releases the product and moves away from the lifting plate 31. Then, the lifting cylinder 30 lowers the lifting plate 31. During this process, the clearance slope 310 gradually approaches the bend of the conveyor belt 10, ensuring that the movement trajectory of the lifting plate 31 is smooth and unobstructed. As the top wall of the lifting plate is fully aligned with the top wall of the conveyor belt 10, a continuous plane is formed. It is precisely because of the seamless connection between the lifting plate 31 and the conveyor belt 10 that the product can be smoothly transferred from the lifting plate 31 to the conveyor belt 10, effectively avoiding jamming or jumping that would affect the quality of the product.

[0050] The pushing mechanism 5 includes a pushing cylinder 50 and a pushing plate 51. The pushing cylinder 50 is installed on the side wall of the conveyor belt 10, and the pushing plate 51 is connected to the output end of the pushing cylinder 50, which is used to push the product on the lifting plate 31 into the conveyor belt 10.

[0051] More preferably, such as Figure 2 As shown, in this embodiment, the moving direction of the pusher plate 51 is parallel to the moving direction of the conveyor belt 10. As the lifting plate 31 and the conveyor belt 10 are placed side by side, the pusher cylinder 50 can drive the pusher plate 51 to move from the outside of the conveyor belt 10 to the inside of the conveyor belt 10. During this process, the movement speed and force of the pusher plate 51 are precisely controlled to ensure that the product is transferred smoothly and safely onto the conveyor belt 10. Once the product has completely left the lifting plate 31 and entered the conveyor belt 10, the pusher cylinder 50 immediately stops, and the pusher plate 51 quickly returns to its initial position to prepare for the next operation. The whole process is fast and efficient, ensuring the smooth connection of the product loading action and ensuring that the speed of the production line is not affected.

[0052] The gripping mechanism 2 also includes: a movable frame 23, movably mounted on the frame 1; a first material transfer module 24, mounted on the movable frame 23, with a mounting frame 25 connected to the movable end of the first material transfer module 24; a drive component 26 and a rotating shaft 27, the drive component 26 being mounted on the mounting frame 25, the mounting frame 25 extending outward to a mounting base 250, the rotating shaft 27 being movably mounted within the mounting base 250, and a pneumatic finger 28 being connected to one end of the rotating shaft 27, a bracket 22 being connected to the pneumatic finger 28, and the other end of the rotating shaft 27 being connected to the output end of the drive component 26 via a coupling 29.

[0053] like Figures 1 to 3 As shown, after the external equipment finishes processing the required product, the drive unit 26 can adjust the relative position of the magnetic block 21 and the gripper 20 according to the instructions of the control system (not shown in the figure). Specifically, after the drive unit 26 is started, it drives the rotating shaft 27 to rotate through the coupling 29, causing the pneumatic finger 28 and its support 22 to flip and change position. Since the gripper 20 and the magnetic block 21 are distributed on the upper and lower sides of the support 22, the gripping method can be matched to the shape of the product to be gripped by this rotation. This design allows the gripping mechanism 2 to complete the conversion between the gripper 20 and the magnetic block 21 in a short time, improving the response speed and adaptability of the equipment. During the gripping process, the first material transfer module 24 drives the mounting frame 25 and all its components to move in the vertical and horizontal directions, which can extend the magnetic block 21 and the gripper 20 out of the conveyor belt 10 and bring them closer to the external equipment. This realizes the free movement of the gripping mechanism 2 in multiple dimensions, expands its operating range, is suitable for production lines with different layouts, and also ensures stable gripping of the processed products.

[0054] Preferably, in this embodiment, a dust removal nozzle 234 can also be installed on the movable frame 23. By aligning the dust removal nozzle 234 with the gripper 20 and the magnetic block 21, the component and the product it grips can be dusted and shavings removed, effectively preventing the product from being affected by impurities or waste and its stability when gripped.

[0055] The positioning mechanism 4 includes: a guide 40, an extension frame 230 connected to the movable frame 23, a conveyor belt 10 rotatably mounted on the extension frame 230, the guide 40 and the conveyor belt 10 together forming a guide cavity 403, and the guide 40 can move relative to the extension frame 230 to adjust the size of the guide cavity 403 for the product to pass through; a limiting block 41 and a detector 42, mounted on the extension frame 230, the limiting block 41 being located at the end of the guide cavity 403 in the length direction, and an anti-detachment groove 410 being formed in the limiting block 41, the product in the guide cavity 403 being transported to the anti-detachment groove 410 by the conveyor belt 10; and the detector 42 being used to detect the position of the product to give the transfer mechanism 6 a signal to grab the product.

[0056] like Figure 4 As shown, in this embodiment, the rotation of the conveyor belt 10 is also achieved by the cooperation of a motor and a synchronous belt, which are commonly used in mechanical structures. As the pusher plate 51 pushes the product from the lifting plate 31 into the conveyor belt 10, the conveyor belt 10 can drive the product to move to the other end. During this process, the product can enter the guide cavity 403 in advance until it reaches the limiting block 41 at the end of the guide cavity 403. The guide cavity 403 ensures that the product moves steadily along the predetermined path and avoids deviation or jamming. The anti-detachment groove 410 design allows the product to slide smoothly into it and is restricted by the limiting block 41 to prevent it from moving further or falling off, which provides a guarantee for the stable gripping of the product by the subsequent transfer mechanism 6. Since the detector 42 monitors the position of the product in the limiting block 41 in real time, once it is confirmed that the product has completely entered the anti-detachment groove 410, the detector 42 immediately sends a signal to the control system. The control system starts the transfer mechanism 6 to perform the next operation (i.e., grab the product from the anti-detachment groove 410 and place it into the material tray 110) according to the received signal.

[0057] The guide member 40 includes a first limiting plate 400 and a second limiting plate 401. An extension plate 404 is formed on both the first limiting plate 400 and the second limiting plate 401. An oblong hole 404a is provided in the extension plate 404. A fastener is installed on the extension frame 230. The fastener can pass through the oblong hole 404a and be connected to the extension frame 230 when the first limiting plate 400 and the second limiting plate 401 are close to or far apart.

[0058] Furthermore, such as Figures 4 to 5As shown, in this embodiment, the first limiting plate 400 and the second limiting plate 401 are both set along the direction of movement of the conveyor belt 10, while the extension plate 404 is perpendicular to the limiting plates in the horizontal direction. By adjusting the distance between the first limiting plate 400 and the second limiting plate 401, it is ensured that each product can accurately reach the designated position according to the predetermined path (i.e., the formed guide cavity 403), reducing operational errors caused by position deviations. It should be noted that in this embodiment, the limiting plates after position adjustment can be locked on the extension frame 230 by fasteners (not shown in the drawings) connected at different positions of the waist-shaped hole 404a. That is, the first limiting plate 400 and the second limiting plate 401 will not move with the conveyor belt 10, ensuring the stability and reliability of the limiting plates in guiding and limiting the products. The overall structure is relatively simple, providing great convenience when adjusting the relative position of the two limiting plates. Preferably, the fasteners in this embodiment can be replaced by screws, bolts, or other connecting components.

[0059] More preferably, such as Figures 4 to 5 As shown, in this embodiment, guide blocks 402 are formed at the ends of the first limiting plate 400 and the second limiting plate 401 away from the limiting block 41. The two guide blocks 402 are arranged in the shape of a flared mouth, with the larger end of the flared mouth facing the lifting plate 31, so that the product pushed into the conveyor belt 10 by the lifting plate 31 can smoothly enter between the first limiting plate 400 and the second limiting plate 401, effectively preventing the product from getting stuck during the conveying process and ensuring the overall efficiency of the entire production line.

[0060] The transfer mechanism 6 includes: a second transfer module 60, which is mounted on the frame 1; a lifting platform 61 and a gripper 62. The lifting platform 61 is connected to the movable end of the second transfer module 60, and the gripper 62 is connected to the lifting platform 61. The frame 1 is also equipped with several feeding belts 11 that hold material trays 110. The gripper 62 is used to grip the products in the anti-detachment groove 410 and transfer them to the material tray 110.

[0061] like Figures 4 to 5 As shown, once the product reaches the anti-detachment groove 410 and the control system receives the corresponding signal, the second transfer module 60 can move freely in the horizontal and vertical directions. Then, the lifting platform 61 aligns the gripper 62 with the product to be gripped. As the gripper 62 extends and grips the product, the second transfer module 60 can move the gripper 62 along the set path to the top of the unloading belt 11 using a secondary action. During this process, the lifting platform 61 remains stable to ensure that the product will not fall off due to shaking. As the lifting platform 61 descends and the gripper 62 approaches the target tray 110, the gripper 62 releases, and the product is gently placed in the tray 110, completing one complete transfer operation. The entire process is repeated to ensure the continuous operation of the production line.

[0062] Preferably, in this embodiment, both the first transfer module 24 and the second transfer module 60 are composed of a horizontal linear guide rail and a vertical linear guide rail. The vertical linear guide rail is connected to the output end of the horizontal linear guide rail, and the lifting platform 61 and the mounting bracket 25 can be connected to the output end of the vertical linear guide rail. Through the cooperation between the two, the required function is achieved. More preferably, this embodiment also includes a slider and a slide rail structure (see reference...). Figure 2 The cooperation between the slider and the slide rail further enhances the stability of the lifting platform 61 and the mounting frame 25 during vertical movement, effectively preventing the lifting platform 61 or the mounting frame 25 from tilting or swaying, which would affect the accuracy and stability of the components gripping the product.

[0063] More preferably, the gripping component 62 in this embodiment can be used in two interchangeable structures, such as... Figure 6 As shown, the gripper 62 includes a gripping cylinder 620 mounted on the lifting platform 61 and symmetrically arranged gripping arms 621. The gripping cylinder 620 drives the two gripping arms 621 to move closer or further apart, thus completing the gripping and releasing of the product; similarly, as... Figure 7 As shown, the gripper 62 uses a lifting cylinder 622 in conjunction with a strong magnetic block 623 to achieve stable gripping of metal products. The two methods can be adapted and adjusted according to actual processing and usage requirements, effectively improving the flexibility of the palletizer during operation.

[0064] More preferably, such as Figures 4 to 5 As shown, in this embodiment, a guide rail 231 is provided along the length of the side wall of the movable frame 23, and several guide blocks 12 are provided along the horizontal direction of the frame 1. The guide rail 231 is movably engaged with the guide blocks 12. It should be noted that in this embodiment, the gripping mechanism 2, lifting mechanism 3, positioning mechanism 4, and pushing mechanism 5 are all located on the frame 1 at a position higher than the installation position of the aforementioned unloading belt 11. Therefore, relying on the cooperation of the guide blocks 12 and the guide rail 231, the movable frame 23 and all the mechanisms on it can move relative to the frame 1 (i.e., along the length of the frame 1). Figure 1 (Moving back and forth in the left and right directions) As the conveyor belt 10 and various mechanisms retract along the frame 1, the distance between the stacking machine and external equipment is increased, so as to provide enough space for workers to change molds on external equipment, making the operation more convenient and faster. Example

[0065] More preferably, such as Figure 4As shown, this second embodiment is an improvement on the first embodiment. Specifically, the movable frame 23 in this second embodiment is also equipped with a fixed bracket 232. An electronic scale 233 located at the end of the conveyor belt 10 is installed on the fixed bracket 232. When the product reaches the anti-detachment groove 410, the gripping member 62 can grip the product and pre-transfer it to the electronic scale 233. The electronic scale 233 can be used to detect whether the weight of the product meets the required usage requirements. If the product meets the requirements, it can be transferred to the material tray 110 of the unloading belt 11 by the gripping member 62 again. If the product does not meet the requirements, the gripping member 62 can grip the product and transfer it to the outside of the frame 1 for storage or rework via the unloading tray 13 set at an inclination inside the frame 1.

[0066] It should be noted that the driving component 26 in this embodiment can be replaced by other driving devices such as stepper motors and servo motors.

[0067] It should be noted that in this invention, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
