Description

Technical Field

[0001] This utility model relates to the field of material supply technology, and in particular to a pallet feeding device. Background Technology

[0002] Current industrial manufacturing is gradually moving towards automated manufacturing. However, in many cases, the assembly of products still requires manual transfer of materials, which is inefficient. In automated processing, robotic arms are the main processing devices, but they require a fixed feeding method to complete tasks with high precision. If workers are used to feed materials, it will lead to increased costs and low efficiency.

[0003] The existing method for pallet feeders still relies on manual feeding. Materials are placed in a pallet, which is then positioned in the gripper area of ​​a robotic arm. After the material in the pallet is removed, a manual person removes it and replaces it with a new pallet containing material for the robotic arm to feed. This manual feeding method requires human observation of the material usage. Once the material in a pallet is removed by the robotic arm, a person must immediately place the new pallet back into the gripper area for the robotic arm to pick up more material. This not only makes pallet replacement inefficient but also results in inaccurate pallet placement due to manual placement, affecting the robotic arm's gripping accuracy and causing missed pickups. From the perspective of processing efficiency and quality, manually replacing pallets is clearly unacceptable.

[0004] Therefore, it is necessary to propose a technical means to solve the above-mentioned defects. Utility Model Content

[0032] Please see Figures 1 to 11 A pallet feeding device, comprising

[0033] The workbench 10 is provided with a first storage component 20 for loading a full material pallet, a second storage component 30 for loading an empty material pallet, and a limiting component 40 for limiting and fixing the full material pallet.

[0034] The first transfer assembly 50 is used to carry the pallet so that the pallet can be moved as needed between the first storage assembly 20, the second storage assembly 30 and the limiting assembly 40.

[0035] The second transfer assembly 60 is used to transfer a full pallet located in the first storage assembly 20 to the first transfer assembly 50, and to transfer an empty pallet located in the second transfer assembly 60 to the second storage assembly 30.

[0036] Specifically, in this embodiment, during operation, the second material transfer component 60 transfers the full pallet located in the first material storage component 20 to the first material transfer component 50. Then, the full pallet moves to the limiting component 40 under the transfer of the first material transfer component 50. The limiting component 40 then limits and fixes the full pallet. After the limiting and fixing, the external robot arm picks up and delivers the material in the full pallet. After the delivery is completed, the limiting component 40 resets and releases the empty pallet. Then, the empty pallet moves to the second material storage component 30 under the drive of the first transfer component. The second material transfer component 60 transfers the empty pallet into the second material storage component 30, thus completing one workflow. After the full pallets in the first material storage component 20 have been transferred, or the empty pallets in the second material storage component 30 have reached the storage limit, the staff can promptly replenish the full pallets in the first material storage component 20, or continue to transfer the empty pallets in the second material storage component 30.

[0037] The pallet feeding device of this utility model, through the arrangement of a first material storage component 20, a second material storage component 30, a limiting component 40, a first material transfer component 50 and a second material transfer component 60, can realize continuous material feeding of pallets, greatly improve industrial production efficiency, and is suitable for industrial applications.

[0038] In one specific embodiment, the first material transfer component 50 includes two conveying rails 501 mounted on the workbench 10 and arranged side by side; in the working state, the tray is located above the two conveying rails 501, and its two ends are supported by the two conveying rails 501 respectively, and move under the drive of the two conveying rails 501; the first material storage component 20, the second material storage component 30 and the limiting component 40 are arranged sequentially along the conveying direction of the conveying rails 501.

[0039] In this embodiment, the conveying track 501 includes a mounting frame 502, first drive wheels 503 mounted at both ends of the mounting frame 502, a drive belt 504 connected to the two first drive wheels 503, a second drive wheel 505 mounted between the two first drive wheels 503 and connected to the drive belt 504, and a first motor 506 connected to the second drive wheel 505 for driving the second drive belt 504 to rotate. Specifically, during operation, the first motor 506 drives the second drive wheel 505 to rotate, thereby causing the drive belt 504 to rotate in cooperation with the two first drive wheels 503, thus moving the tray placed above the drive belt 504 as needed. Furthermore, the drive belts 504 are respectively mounted on the sides of the two mounting frames 502 that are close to each other. The first motor 506 is mounted between the two mounting frames 502, which makes the structure compact and saves space.

[0040] In one specific embodiment, the first storage assembly 20 includes a first cylinder 201 and a clamping plate 202; the first cylinder 201 is symmetrically installed on the opposite side of the mounting bracket 502, with its power output end facing the inner side of the two mounting brackets 502; the clamping plate 202 is installed on the power output end of the first cylinder 201; the second storage assembly 30 includes a connecting seat 301, a rotating shaft 302, and a rocker 303; the connecting seat 301 is symmetrically installed on the opposite side of the two mounting brackets 502; the rotating shaft 302 is installed on the opposite side of the two connecting seats 301, and is rotatably connected to the connecting seats 301; the rocker 303 is installed on the rotating shaft 302; the second material transfer assembly 60 includes a bracket 601 and a first lifting unit; the bracket 601 is installed on the two mounting brackets 502 and is located below the clamping plate 202 and the rocker 303; the first lifting unit is installed below the worktable 10 and is connected to the bracket 601, for driving the bracket 601 to move vertically.

[0041] Specifically, in this embodiment, under normal conditions, the first cylinder 201 drives the clamping plate 202 to output towards the inner side of the two mounting brackets 502. Full material trays are stacked on top of the two symmetrically arranged clamping plates 202, with the two ends of the bottom full material tray 601 supported by the clamping plates 202. Empty material trays 601 are stacked on top of the two symmetrically arranged rocker arms 303, with the two ends of the bottom empty material tray supported by the rocker arms 303. During operation, the first lifting unit drives the tray 601 to move upwards, causing the tray 601 to move and contact the bottom full material tray 601. At this time, the first... A cylinder 201 drives the clamping plate 202 to retract, thus removing the support from the bottom full pallet. The support then shifts to the bracket 601. At this time, the first lifting unit controls the bracket 601 to descend, causing the bottom full pallet and its bracket 601 to descend together. After descending to one pallet unit, the first cylinder 201 drives the clamping plate 202 to extend, allowing it to support the full pallet again. The clamping plate 202 then supports the full pallet in the second row from the bottom. The bottommost full pallet continues to be supported by the bracket 601 and the first lifting unit. Driven by the first lifting unit, the material moves downwards until both ends are placed on the two transmission belts 504. The transmission belts 504 then continue to support the material, completing the process of picking up and transferring the full pallet to the transmission belts 504. The transmission belts 504 then transfer the full pallet to the limiting component 40 for positioning and fixing. After the external robot finishes picking up the material, the transmission belts 504 transfer it to the workstation of the second storage component 30. At this time, the empty pallet is located between the symmetrically arranged connecting seats 301. Then, the bracket 601 moves upwards driven by the first lifting unit, supporting the empty bracket 601 so that... As the empty pallet moves away from the drive belt 504, its end contacts the bottom of the rocker arm 303. During the upward movement, the rocker arm 303 is driven to rotate upward via the rotating shaft 302. When the bracket 601 lifts the empty pallet to a certain height, the empty pallet separates from the rocker arm 303, and the rocker arm 303 rotates downward to reset. At this time, the bracket 601 moves downward under the drive of the first lifting unit. During the downward movement, the end of the empty pallet is supported by the rocker arm 303, thus separating from the bracket 601. This completes the transfer of the empty pallet.

[0042] Furthermore, two first cylinders 201 are arranged side by side on the same mounting bracket 502 so that when supporting the full material pallet, the four ends of the full material pallet can be effectively supported, thereby improving the stability of the support.

[0043] Furthermore, two connecting seats 301 are arranged side by side on the same mounting bracket 502 so that when supporting the empty material pallet, the four ends of the empty material pallet can be effectively supported, thereby improving the stability of the support.

[0044] Furthermore, the bottom of the bracket 601 is provided with a slot for the card plate 202 to engage, so that after the stacked full pallets move down one pallet unit under the drive of the bracket 601, the card plate 202 can effectively engage into the slot of the full pallet in the second row of the bottom layer, thereby supporting the full pallet and the full pallets on it.

[0045] Furthermore, the pallet 202 and the rocker 303 are at the same height. During operation, when the empty pallet moves to the work position of the second storage component 30, that is, between the two symmetrically arranged connecting seats 301, the first lifting unit drives the bracket 601 to move upward, so that the empty pallet contacts the rocker 303. At this time, the bracket 601 also contacts the bottom full pallet. As the bracket 601 continues to move upward, the empty pallet pushes away the rocker 303. At this time, the bracket 601 also drives the stacked full pallets on it to move upward until they are completely separated from the rocker 303. Then the first lifting unit... The unit drives the abutment bracket 601 downwards. During the downward movement of the bracket 601, the rocker arm 303 prevents the empty pallet from moving downwards with the bracket 601, thus effectively separating it from the bracket 601. Due to the first cylinder 201 and the clamping plate 202, the bottom full pallet moves downwards with the bracket 601, while the remaining full pallets remain stably stacked and limited above the clamping plate 202. In this embodiment, through the above-mentioned configuration, the picking and dropping of full pallets can be completed during the transfer and stacking of empty pallets, improving industrial efficiency and making it suitable for industrial applications.

[0046] Furthermore, the upper end of the connecting seat 301 near the mounting bracket 502 is provided with a mounting groove 304; the rotating shaft 302 is rotatably installed in the mounting groove 304, the rocker 303 is installed on the rotating shaft 302, and the lower part of the free end of the rocker 303 is provided with an inclined surface 305 for the empty material pallet to abut against. By setting the inclined surface 305, the empty material pallet can effectively push the rocker 303 to swing upward through the rotating shaft 302.

[0047] In one specific embodiment, the first lifting unit includes a first lifting plate 602 installed below the workbench 10, a transmission screw 603 connected to the first lifting plate 602 for driving the first lifting plate 602 to rise and fall vertically during rotation, a second motor 604 connected to the transmission screw 603 for driving the transmission screw 603 to rotate, and a connecting column 605 connected to the first lifting plate 602 and the bracket 601 for rising and falling with the first lifting plate 602, thereby driving the bracket 601 to rise and fall as needed. Specifically, in this embodiment, the second motor 604 drives the transmission screw 603 to rotate, thereby driving the first lifting plate 602 to rise and fall as needed, thereby driving the bracket 601 to rise and fall as needed through the connecting column 605. It should be noted that this setting is a traditional screw drive, designed to drive the bracket 601 to rise and fall digitally as needed, so this structural setting will not be described in detail. Those skilled in the art can also use other technical means to drive the bracket 601 to rise and fall vertically, such as connecting the bracket 601 with a cylinder to drive the bracket 601 to rise and fall vertically.

[0048] In one specific embodiment, the limiting component 40 includes a second lifting plate 401 installed between two mounting brackets 502 and located at the end of the mounting brackets 502, a second lifting unit installed below the second lifting plate 401 for driving the second lifting plate 401 to rise and fall, and a pressing plate 402 symmetrically installed at the ends of the two mounting brackets 502 for pressing against the upper part of the tray when the second lifting plate 401 moves upward to drive the tray upward. Specifically, in this embodiment, during operation, when the full pallet moves to the end of the mounting frame 502 under the drive of the conveyor belt, the full pallet is located between the pressure plate 402 and the second lifting plate 401. Then, the second lifting unit pushes the second lifting plate 401 upward so that it abuts against the full pallet and drives the full pallet upward to disengage from the conveyor belt until the upper part of the full pallet abuts against the pressure plate, thereby making the full pallet reach the limit and fix. After the external robot arm finishes picking up the material from the full pallet, the second lifting unit drives the second lifting plate 401 downward so that the empty pallet after picking up the material returns to the conveyor belt and moves to the work position of the second storage component 30 under the drive of the conveyor belt.

[0049] In one specific embodiment, the second lifting unit includes a second cylinder 403 installed below the second lifting plate 401 for driving the second lifting plate 401 to rise and fall.

[0050] In one specific embodiment, a sensor assembly is also included; the sensor assembly includes a first sensor 701 arranged along the mounting bracket 502 for monitoring the position of the tray. Specifically, two first sensors 701 are arranged along the length of the mounting bracket 502 and installed on the inner side of the mounting bracket 502. The two first sensors 701 are respectively installed on one side of the first cylinder 201 and one side of the connecting seat 301 for monitoring the position of the tray moving to the first storage assembly 20 and the second storage assembly 30, so as to indicate the operation of the second transfer assembly 60.

[0051] Furthermore, the sensor assembly also includes a second sensor 702 adjacent to one side of the first cylinder 201, and a third sensor 703 adjacent to and above the connecting seat 301. Specifically, the second sensor 702 monitors the presence or absence of the bottom full pallet; when the bottom full pallet has been moved, it notifies the staff to replenish the full pallet. The third sensor 703 monitors the presence or absence of the top empty pallet; when the second storage assembly 30 reaches the maximum load capacity of the empty pallet, it notifies the staff to remove the empty pallet. Specifically, the first sensor 701, the second sensor 702, and the third sensor 703 are all photoelectric sensors.

[0052] The pallet feeding device of this utility model, through the arrangement of a first material storage component 20, a second material storage component 30, a limiting component 40, a first material transfer component 50 and a second material transfer component 60, can realize continuous material feeding of pallets, greatly improve industrial production efficiency, and is suitable for industrial applications.

[0053] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
