Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a precious metal processing device and its stacking mechanism. Background Technology

[0002] In the recycling, refining, and jewelry manufacturing processes of precious metals (such as gold, silver, and platinum), palletizing is typically required after a series of processing operations for subsequent transportation and storage. Existing palletizing devices generally fall into two categories: mobile palletizing devices, such as palletizing robots, which can perform palletizing operations at different workstations, but require high-performance robots with complex structures and high costs; and fixed palletizing devices, which have relatively simple structures but can usually only perform palletizing operations at a single workstation. When multiple palletizing workstations exist, a palletizing device needs to be installed for each workstation, which also increases production costs.

[0003] Therefore, how to balance multi-station palletizing and production costs has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides a precious metal processing device and its stacking mechanism to solve the above problems.

[0005] On the one hand, this application provides a palletizing mechanism, including a machine base and a feeding component and a palletizing component disposed on the machine base, wherein the machine base is provided with a material discharge port, and the palletizing mechanism forms a plurality of palletizing spaces below the material discharge port; The palletizing assembly includes a gripper, a first palletizing driver, and a second palletizing driver. The gripper is used to grip materials. The first palletizing driver is connected to the gripper and is used to drive the gripper to move vertically in the longitudinal direction. The second palletizing driver is connected to the gripper and is used to drive the gripper to move horizontally in the transverse direction. The longitudinal direction and the transverse direction are perpendicular to each other. A plurality of palletizing spaces are arranged along the transverse direction. The feeding assembly can move relative to the gripper to transport the materials to the gripper.

[0006] On the other hand, this application also provides a precious metal processing apparatus, including the palletizing mechanism described above.

[0007] The palletizing mechanism provided by this utility model allows the gripper to move downwards under the drive of the first palletizing driver, carrying material through the discharge port into the palletizing space to complete the palletizing operation. A horizontally arranged palletizing space is formed below the discharge port. The second palletizing driver can drive the gripper to move horizontally, thus enabling the gripper to move from one palletizing space to another, achieving palletizing operations in different spaces. The palletizing assembly can achieve palletizing operations in different spaces through two palletizing drivers, eliminating the need for a separate palletizing assembly for each space. This allows the palletizing mechanism to perform palletizing operations in different spaces while maintaining a relatively simple overall structure and reducing production costs.

Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0011] It should be noted that all directional indicators (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0012] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.

[0013] Please see Figures 1 to 6 This utility model provides a palletizing mechanism 100 for a precious metal processing apparatus. The palletizing mechanism 100 includes a machine base 10, a feeding assembly 12, and a palletizing assembly 14. The machine base 10 supports the feeding assembly 12 and the palletizing assembly 14, and has a through-hole 16 for material 200 to pass through. A palletizing space is formed below the feeding hole 16 for palletizing the material 200. The feeding assembly 12 is mounted on the machine base 10 and can move relative to the machine base 10, and is used to move the material 200 to the palletizing assembly 14. The palletizing assembly 14 grips the material 200 and moves it. The palletizing assembly 14 can move the material 200 downwards from above the feeding hole 16, through the feeding hole 16, and into the palletizing space, so as to palletize the material 200 within the palletizing space. In an optional example, the material 200 is a pallet containing processed precious metal, and the palletizing assembly 14 grips the pallet and pallets it.

[0014] The palletizing assembly 14 includes a gripper 18, a first palletizing drive 20, and a second palletizing drive 22. The gripper 18 grips the material 200 and moves it along with the material 200. The first palletizing drive 20 is connected to the gripper 18 and drives the gripper 18 to move up and down along the longitudinal direction Y, thereby moving the gripped material 200 along the longitudinal direction Y. When the gripper 18 moves downward under the action of the first palletizing drive 20, it can move the material 200 downward together and pass through the material drop port 16, so that the material 200 enters the palletizing space. The gripper 18 releases the material 200 and stores the material 200 in the palletizing space. Then it rises and grips the transported material 200 again. After repeating this action, multiple materials 200 can be stacked in the palletizing space to complete the palletizing operation.

[0015] The second palletizing drive 22 is connected to the gripper 18 and is used to drive the gripper 18 to extend and retract along the horizontal X direction. The horizontal X direction and the vertical Y direction are two mutually perpendicular directions. In an optional example, the vertical Y direction is the vertical direction, and the horizontal X direction is a horizontal direction, such as the front-back direction or the left-right direction. Multiple stacking spaces are formed below the material inlet 16, arranged along the horizontal X direction. When the second stacking drive 22 drives the gripper 18 to move along the horizontal X direction, the gripper 18 can move from one stacking space to another, thereby moving the material 200 to another stacking space. Therefore, after the stacking assembly 14 completes the stacking operation in one stacking space under the action of the first stacking drive 20, the second stacking drive 22 can move the gripper 18 from that stacking space to another stacking space, and complete the stacking operation in the other stacking space under the action of the first stacking drive 20. In this way, the stacking assembly 14 can achieve stacking operation in different stacking spaces with the cooperation of the two stacking drives, without the need to set up a stacking assembly 14 for each stacking space. This makes the stacking mechanism 100 able to perform stacking operations in different stacking spaces while keeping the overall structure relatively simple and reducing production costs.

[0016] The specific types of the first palletizing drive component 20 and the second palletizing drive component 22 are not limited. For example, they can be motors, cylinders, hydraulic cylinders, etc., as long as they can drive the gripper 18 to perform mechanical movement. When the first palletizing drive component 20 drives the gripper 18 to move up and down in the longitudinal Y direction, the gripper 18 can drive the second palletizing drive component 22 to move together, or it can move relative to the second palletizing drive component 22. That is, the gripper 18 and the second palletizing drive component 22 can be in a relatively fixed relationship or in a movable cooperation relationship in the longitudinal Y direction. Similarly, when the second palletizing drive component 22 drives the gripper 18 to move forward and backward in the transverse X direction, the gripper 18 can drive the first palletizing drive component 20 to move together, or it can move relative to the first palletizing drive component 20.

[0017] The gripper 18 can grip the material 200 by clamping, magnetic attraction, or snap-fit, as long as the gripper 18 can move the material 200.

[0018] The specific number of palletizing spaces can be set according to actual conditions and needs, such as two, three or more. In one optional example, the number of palletizing spaces is two.

[0019] Optionally, a trailer or pallet can be installed below the material inlet 16. The material 200 can be stacked and stored on the trailer or pallet. After the stacking is completed, the material 200 can be transferred by the trailer or pallet.

[0020] In one embodiment, the palletizing assembly 14 includes a palletizing mounting frame 24, which is fixed relative to the machine base 10 in the longitudinal Y direction, thus preventing movement of the palletizing mounting frame 24 relative to the machine base 10 in the longitudinal Y direction. The palletizing mounting frame 24 is movably connected to the machine base 10 in the transverse X direction, allowing movement of the palletizing mounting frame 24 relative to the machine base 10 in the transverse X direction. A gripper 18 and a low-level palletizing drive are both mounted on the palletizing mounting frame 24. A second palletizing drive 22 is mounted on the machine base 10 and connected to the palletizing mounting frame 24. The second palletizing drive 22 drives the palletizing mounting frame 24 to move relative to the machine base 10 in the transverse X direction, thereby causing the gripper 18 and the first palletizing drive 20 to move in the transverse X direction. The first palletizing drive 20 and the gripper 18 are kept relatively fixed in the transverse X direction, and the two can move together in the transverse X direction. The first palletizing drive 20 drives the gripper 18 to move relative to the palletizing mounting frame 24 and the second palletizing drive 22 in the longitudinal Y direction, which can effectively avoid the problem of mutual interference when the first palletizing drive 20 and the second palletizing drive 22 drive the gripper 18 to move in different directions.

[0021] Optionally, a slide rail is fixedly installed on the machine base 10, extending along the transverse X direction. A slider is fixedly installed on the palletizing mounting frame 24, and the slider slides in cooperation with the slide rail, thereby forming a movable connection between the palletizing mounting frame 24 and the machine base 10 in the transverse X direction. The second palletizing drive component 22 includes a cylinder, and the piston of the cylinder is fixed relative to the palletizing mounting frame 24 in the transverse X direction. When the piston of the cylinder performs telescopic movement, it can drive the palletizing mounting frame 24, the gripper 18 on the palletizing mounting frame 24, and the first palletizing drive component 20 to move together.

[0022] The palletizing mounting frame 24 includes a sliding part 26 and a mounting part 28 fixed relative to the sliding part 26. The sliding part 26 is located on the outer side of the material discharge port 16 in the transverse direction X. The sliding part 26 is slidably engaged with the machine base 10. Optionally, the sliding part 26 and the machine base 10 are slidably engaged by a slider and a slide rail. The second palletizing drive member 22 is connected to the sliding part 26 to drive the sliding part 26 to slide relative to the machine base 10 in the transverse direction X, and to drive the mounting part 28 to move together. The mounting part 28 extends in the longitudinal direction Y and passes through the material discharge port 16. The gripper 18 is movably mounted on the mounting part 28. The first palletizing drive member 20 is located on the top of the mounting part 28 and is used to drive the gripper 18 to move up and down relative to the mounting part 28.

[0023] In one embodiment, the gripper 18 includes a clamping drive 30 and two grippers 32 respectively disposed on opposite sides of the clamping drive 30. A first stacking drive 20 is connected to the clamping drive 30 to drive the clamping drive 30 to perform lifting and lowering movements, and the clamping drive 30 drives the gripper to perform lifting and lowering movements together. The two grippers 32 are located on opposite sides of the clamping drive 30 and are connected to the clamping drive 30 for transmission, so that the two grippers 32 can move closer to each other or further apart under the action of the clamping drive 30. When the two grippers 32 move closer to each other, they can clamp the material 200, thereby driving the material 200 to move together. When the two grippers 32 move further apart, they can release the material 200, thereby placing the material 200 on the corresponding stacking position.

[0024] The two grippers 32 can move closer or further apart by rotating or by extending or retracting. In an optional example, the gripping drive 30 is a double-rod cylinder. The double-rod cylinder is connected to the two grippers 32 through different pistons. The two grippers 32 can extend or retract under the action of the pistons, thereby moving closer or further apart.

[0025] The inner side of the gripper 32 is provided with a groove 34, which is U-shaped. When the gripper 32 clamps the material 200, the gripper 32 can form a concave-convex fit with the material 200 through the groove 34. That is, a part of the material 200 is inserted into the groove 34, thereby forming a concave-convex fit. In this way, the gripper 18 can not only limit the material 200 in the longitudinal Y direction through the clamping force of the gripper 32, but also limit the material 200 in the longitudinal Y direction through the concave-convex fit. The gripper 18 makes the movement of the material 200 more stable and reliable, reducing the risk of the material 200 falling off the gripper 18.

[0026] In one embodiment, the palletizing mechanism 100 further includes two support members 36, which are located on opposite sides of the material inlet 16 and arranged perpendicular to the transverse X and longitudinal Y directions. For example, when the longitudinal Y is vertical and the transverse X is front-to-back, the two support members 36 are spaced apart in the left-to-right direction. The feeding assembly 12 is used to transport the material 200 to the support members 36, where the material 200 is supported by the two support members 36. The second palletizing drive 22 can drive the gripper 18 to move in the transverse X direction toward or away from the support members 36. After the feeding assembly 12 transports the material 200 to the support members 36, the second palletizing drive 22 can drive the gripper 18 to move toward the support members 36. After the gripper 18 grasps the material 200, it can move away from the support members 36 under the action of the second palletizing drive 22, thus separating the material 200 from the support members 36.

[0027] The distance between the two support members 36 is adjustable. When the distance between the two support members 36 decreases and is less than the width of the material 200, the two support members 36 can be used to support the material 200. When the distance between the two support members 36 increases and is greater than the width of the material 200, the material 200 separates from the support members 36. At this time, the gripper 18 can drive the material 200 to move downward between the two support members 36.

[0028] Each support member 36 includes a support portion 38 and a support drive member 40. Two support portions 38 are spaced apart and opposite to each other and are used to support the material 200. The support drive member 40 is connected to the support portion 38. The two support portions 38 can move closer to each other or further away from each other under the drive of the two support drive members 40. That is, when the support drive member 40 drives the corresponding support portion 38 to move towards the other support portion 38, the distance between the two support portions 38 decreases to support the material 200. When the support drive member 40 drives the corresponding support portion 38 to move away from the other support portion 38, the distance between the two support portions 38 increases to release the material 200. Since the two support parts 38 can move closer or further apart under the action of the support drive member 40, when it is necessary to support the material 200, the two support parts 38 can be moved closer together first. After the gripper 18 grips the material 200 on the support part 38, the two support parts 38 can be driven to move further apart, so that the material 200 and the support member 36 are freed from interference in the longitudinal Y direction. This allows the gripper 18 to drive the material 200 to move downward from the position between the two support members 36. Therefore, a palletizing area can be set below the part of the discharge port 16 located between the two support members 36, which can make full use of the space under the machine 10 and help reduce the overall volume of the palletizing mechanism 100.

[0029] Optionally, the support drive component 40 is a cylinder. The cylinder is mounted on the machine base 10 through a support plate, so that the cylinder is suspended relative to the machine base 10. The piston of the cylinder is connected to the support part 38, thereby driving the support part 38 to perform telescopic movement, so that the two support parts 38 move closer to each other or further away from each other.

[0030] Each support member 36 also includes multiple bearings 42 disposed inside the support portion 38, where "inner" refers to the two opposing sides of the two support portions 38. The multiple bearings 42 are rotatably mounted on the support portion 38 and arranged sequentially along the transverse X direction. The support portion 38 supports the material 200 through the bearings 42. The feeding assembly 12 moves the material 200 to the two support members 36 along the transverse X direction. When the feeding assembly 12 moves the material 200 along the transverse X direction, the material 200 slides on the bearings 42, causing the bearings 42 to rotate relative to the support portion 38, thereby reducing the friction between the material 200 and the support member 36 and facilitating the feeding assembly 12 to transport the material 200 to the corresponding position on the support member 36.

[0031] In an alternative example, the precious metal processing apparatus includes a conveyor line located on the side of the support 36 away from the gripper 18, and the conveyor line transports material 200 in a transverse direction X. A blocking structure is provided at one end of the conveyor line near the support 36 to prevent the material 200 from falling off the conveyor line. Once the two supports 36 move closer together to support the material 200, the blocking structure is released, and the feeding assembly 12 can transport the material 200 from the conveyor line to the corresponding position on the support 36. The blocking structure can be a cylinder; when the piston of the cylinder extends, the cylinder blocks the material 200; when the piston retracts, the cylinder no longer blocks the material 200.

[0032] In one embodiment, the feeding assembly 12 includes a feeding member 44, a first feeding drive member 46, and a second feeding drive member 48. The feeding member 44 is used to connect with the material 200 and drive the material 200 to move. The feeding member 44 and the gripper 18 are arranged along the transverse X direction, respectively located on opposite sides of the support member 36, and both can move relative to the support member 36 along the transverse X direction. The feeding member 44 can move towards the support member 36 to transport the material 200 to the support member 36, and the gripper 18 can move towards the support member 36 to grip the material 200 on the support member 36.

[0033] The first feeding drive 46 is connected to the feeding member 44 to drive the feeding member 44 to move up and down in the longitudinal direction Y. When the feeding member 44 moves upward, it can connect with the material 200, and when it moves downward, it can disconnect from the material 200. The second feeding drive 48 is used to drive the feeding member 44 to move forward and backward in the transverse direction X, so that the feeding member 44 moves closer to or away from the support member 36. When the feeding member 44 moves in the direction closer to the support member 36, it can transport the material 200 to the support member 36.

[0034] During the material transport process, the feeding assembly 12 first moves the feeding component 44 laterally (X) to the position of the material 200 under the action of the second feeding drive 48. Then, the first feeding drive 46 drives the feeding component 44 upward, connecting the feeding component 44 with the material 200. Next, the second feeding drive 48 moves the feeding component 44 towards the support member 36, and together with the connected material 200, moves towards the support member 36, transporting the material 200 to the position of the material 200. After the support member 36 is in the corresponding position (i.e., the position where the gripper 32 can grasp the material 200), the first feeding drive member 46 drives the feeding member 44 to move downward, so that the feeding member 44 is separated from the material 200. At this time, the material 200 is supported by the two support members 36. Then, the second feeding drive member 48 drives the feeding member 44 to move away from the support member 36, so that the feeding member 44 is moved away from the material 200. The gripper 32 will not be affected by the feeding component 12 during the process of grasping and transferring the material 200.

[0035] Optionally, the feeding component 44 connects to the material 200 via a plug-in connection, a snap-fit ​​connection, or a magnetic connection, as long as the feeding component 44 can move the material 200 together. In an optional example, the material 200 has a slot near its edge, and the top of the feeding component 44 can be inserted into or removed from the slot under the action of the first feeding drive component 46, thereby achieving connection and separation between the feeding component 44 and the material 200. The feeding component 44 and the material 200 are plugged in; the feeding component 44 can connect to the material 200 when it rises and disconnect from the material 200 when it falls. The connection and disconnection operations are simple, allowing the feeding component 44 to transport the material 200.

[0036] The specific types of the first feeding drive 46 and the second feeding drive 48 are not limited, such as motors, cylinders, hydraulic cylinders, etc. In an optional example, both the first feeding drive 46 and the second feeding drive 48 are cylinders, and the feeding member 44 is driven to reciprocate in the longitudinal Y or transverse X direction by the extension and retraction of the piston.

[0037] The feeding assembly 12 also includes a feeding mounting frame 50, which is movable relative to the machine base 10 in the transverse X direction and remains relatively fixed to the machine base 10 in the longitudinal Y direction. A first feeding drive 46 and a feeding component 44 are both mounted on the mounting frame. The first feeding drive 46 drives the feeding component 44 to move up and down relative to the mounting frame. A second feeding drive 48 is connected to the feeding mounting frame 50 and drives the feeding mounting frame 50 to move relative to the machine base 10 in the transverse X direction, thereby moving the feeding component 44 and the first feeding drive 46 together. By assembling the first feeding drive 46 and the second feeding drive 48 together using the feeding mounting frame 50, mutual interference can be avoided when the first feeding drive 46 and the second feeding drive 48 drive the feeding component 44 to move in different directions.

[0038] The second feeding drive 48 is a cylinder. The cylinder barrel is fixed on the machine base 10. The feeding mounting bracket 50 is movably engaged with the cylinder barrel, for example, through a slider and a slide rail. The piston of the cylinder is connected to the feeding mounting bracket 50 to drive the mounting bracket to slide relative to the cylinder barrel in the lateral X direction, and drive the feeding component 44 and the first feeding drive 46 to move.

[0039] In one embodiment, two stacking spaces are formed below the material discharge port 16. One stacking space is located between the two support members 36 and is defined as the first stacking space. The first stacking space is relatively close to the conveyor line of the precious metal processing device. The other stacking space is located on the side of the first stacking space away from the conveyor line and is defined as the second stacking space. One end of the conveyor line is located near the support member 36. After the conveyor line transports the material 200 to the end near the support member 36, it first blocks the material 200 through a blocking structure, and then the support drive member 40 drives the two support parts 38 to move closer to each other. When the support parts 38 move to the position to support the material 200, the blocking structure is released from the material 200. The feeding part 44 rises under the action of the first feeding drive member 46 and inserts into the slot of the material 200. Then, under the action of the second feeding drive member 48, it moves away from the conveyor line and moves the material 200 together. After the feeding part 44 transports the material 200 to the corresponding position of the support member 36, the first feeding drive member 46 drives the feeding part 44 to descend, so that the top of the feeding part 44 exits from the slot. Then, under the drive of the second feeding drive member 48, it moves towards the conveyor line, so that the feeding part 44 moves away from the bottom of the material 200. At this time, the material 200 is located above the first stacking space. The gripper 18 moves toward the material 200 under the drive of the second palletizing drive 22. After the gripper 18 clamps the material 200, the two support parts 38 move away from each other and separate from the material 200. Under the drive of the first palletizing drive 20, the gripper 18 moves the material 200 downward and stacks the material 200 in the first palletizing space. Then, the gripper 18 is driven upward by the first palletizing drive 20 to prepare for the next gripping of the material 200. The above operation is repeated. After the palletizing operation in the first palletizing space is completed, after the gripper 18 clamps the material 200, it moves from above the first palletizing space to above the second palletizing space under the drive of the second palletizing drive 22, and at the same time moves the material 200 to above the second palletizing space. Then, the material 200 is stacked in the second palletizing space until the palletizing operation in the second palletizing space is completed.

[0040] This utility model also provides a precious metal processing apparatus, including a conveyor line and a palletizing mechanism 100. The specific structure of the palletizing mechanism 100 can be referred to the description of the above embodiments. Since the precious metal processing apparatus adopts the above-described palletizing mechanism 100, it has at least all the beneficial effects brought about by the palletizing mechanism 100 in the above embodiments, which will not be elaborated here.

[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
