Description

Technical Field

[0001] This invention relates to the field of automatic feeding technology, and in particular to a batch feeding device. Background Technology

[0002] Workpieces often have coatings on their surfaces after auxiliary product processing. To improve the quality of subsequent processes, sandblasting is typically used to clean the workpiece surface. Currently, common sandblasting equipment is usually used in conjunction with a conveyor line. Workpieces are placed on the conveyor line manually or by a robotic arm and then enter the sandblasting area to complete the cleaning process.

[0003] However, manual material loading is labor-intensive, and its efficiency is affected by personnel fatigue and skill level. It is also not conducive to the stable control of production rhythm. Although robotic arms can reduce labor costs, most still use a single-piece sequential gripping and placing mode, and the material loading rhythm is difficult to match the operating requirements of high-speed conveyor lines, thus limiting the improvement of overall production efficiency.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

[0005] The purpose of this invention is to provide a batch feeding device to greatly improve feeding efficiency.

[0006] The objective of this invention is achieved through the following technical solution: a batch feeding device, comprising: The tray dispensing device stores several trays containing workpieces to be cleaned and can dispense the trays one by one. The material tray transfer device includes a first material tray transfer line arranged along the Y-axis and a transfer platform located below the first material tray transfer line. The first material tray transfer line is used to receive the material tray issued by the tray issuing device and transfer it to a first position. The material transfer device includes a workpiece conveyor line and a side-pushing mechanism. The workpiece conveyor line is arranged along the X-axis direction, with its input end located on one side of the first material tray transfer line in the X-axis direction, and its output end connected to the conveyor line of the sandblasting equipment. A tray collection device is used to collect empty trays. The material tray has at least one storage compartment along the Y-axis, and each storage compartment has several workpieces placed side by side along the X-axis. When the material tray is moved to the first position, the transfer platform is adapted to lift the material tray, the side pushing mechanism is adapted to push the entire row of workpieces from the material tray into the workpiece conveying line along the X-axis, and the transfer platform is adapted to transfer the empty material tray to the second position and place it in the receiving device.

[0007] Furthermore, the issuing device includes: The material frame has open sides on both sides in the Y-axis direction, and the inner cavity of the material frame is provided with multiple sets of support components for carrying material trays at intervals along the Z-axis direction. A material frame lifting module is connected to the material frame drive to drive the material frame to move up and down along the Z-axis; The material tray feeding line is arranged along the Y-axis direction and passes through the material frame; The material frame can rise to its initial position, so that the material tray loading line is located below the bottommost support component, and the material frame can drive the support components to descend one by one to below the material tray loading line, so that the material trays on each support component are placed one by one on the material tray loading line.

[0008] Furthermore, the support assembly includes two support members at the same horizontal height and respectively connected to both sides of the inner cavity of the material frame in the X-axis direction. The two support members cooperate to support the material tray, and the material tray loading line is located between the two support members.

[0009] Furthermore, the transfer platform includes: The platform is used to support the material tray; The transfer module has a base at its output end; A platform lifting module is mounted on the base and is connected to the platform body via a transmission mechanism. The transfer module is adapted to drive the platform to move along the Y-axis to the first position or the second position, and the platform lifting module is adapted to drive the platform to descend along the Z-axis to avoid obstructing the flow of the material tray on the first material tray transfer line, or to rise along the Z-axis to lift the material tray.

[0010] Furthermore, the closing device includes: The second material tray conveyor line is arranged along the Y-axis direction and is located below the first material tray conveyor line; The first lifting platform is located at the second position. When the material tray moves to the second position, the first lifting platform can rise to support the material tray and drive the material tray to fall, so as to place the material tray on the second material tray transfer line.

[0011] Furthermore, the transfer platform includes a platform for supporting the material tray, the platform comprising: Base plate; Support bars are connected to the base plate. There are two support bars, which are respectively located on both sides of the base plate in the X-axis direction. The support bars extend out of the base plate along the conveying direction of the first material tray flow line. The part of the support bar outside the base plate is used to support the material tray. When the tray moves to the second position along with the platform, the first lifting platform is adapted to rise between the two support bars to support the tray.

[0012] Furthermore, the tray receiving device includes a tray receiving mechanism connected to the output end of the second tray conveyor line, the tray receiving mechanism being used to receive and stack the trays output by the second tray conveyor line.

[0013] Furthermore, the closing mechanism includes: The frame has internal storage cavities. A roller line is located near the top of the storage cavity. The roller line is an inclined line with a high end and a low end in the Y-axis direction. The high end of the roller line is connected to the output end of the second material tray transfer line, and the material tray can flow from the high end to the low end of the roller line. Second lifting platform; A closing trolley, including a closing frame, is capable of being pushed into the storage cavity and positioning the second lifting platform corresponding to the closing frame; The second lifting platform is adapted to stack and receive the trays at the lower end of the roller line and gradually descend, and the receiving frame is adapted to accommodate the trays stacked and descending on the second lifting platform.

[0014] Furthermore, the roller line includes: A substrate is connected to the inner wall of the storage cavity; A first line is disposed on the substrate and is used to support and transport a tray. The first line has a high end and a low end. The high end of the first line is connected to the output end of the second tray conveyor line. The second line has a high end and a low end. The high end of the second line is not higher than the low end of the first line and is connected to the low end of the first line. The second line includes two sets of second roller assemblies arranged opposite to each other along the X-axis. A feeding drive is disposed on the substrate, and the feeding drive corresponds one-to-one with the second line body, and its output end is connected to the second line body; The second lifting platform is located in the lower area between the two sets of the second roller assemblies. The two sets of the second roller assemblies can move away from each other along the X-axis under the drive of the feeding drive to make the material tray detach from the second line body, or move closer to each other to support the material tray.

[0015] Furthermore, the substrate is rotatably connected to the storage cavity about the X-axis, and the roller line includes an adjustment drive that can push or pull the substrate to rotate in order to adjust the tilt of the roller line.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts the above-mentioned structure, using a tray pre-loaded with multiple workpieces as a unit for continuous supply, and a side-push mechanism pushes the entire row of workpieces into the workpiece conveyor line at one time, which significantly increases the number of materials loaded in a single action, thereby breaking through the speed limit of the traditional single-piece gripping and releasing mode, and can perfectly match the capacity requirements of the high-speed sandblasting conveyor line, achieving a doubling of production efficiency; At the same time, the closed-loop automation of the entire process from tray distribution, transfer positioning, material pushing and loading to empty tray recycling not only completely replaces manual labor, eliminating the fluctuation of cycle time and quality risks caused by personnel fatigue and operational differences, ensuring the stability of the production cycle, but also significantly reduces labor costs; In addition, the workpieces are transferred in a row by the side-push mechanism in the lifted tray, and the workpieces can flow into the workpiece conveyor line continuously and closely together, which greatly reduces the positioning error and the risk of collision and jamming compared with the gripping and releasing of the robotic arm, improves the reliability of the loading process, and further ensures the continuous and smooth operation of the entire production line.

It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0027] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0028] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] Please see Figure 1 and Figure 3 As shown, a batch feeding device corresponding to a preferred embodiment of the present invention includes: a tray issuing device 100, which stores a plurality of trays 500 containing workpieces 520 to be cleaned, and is capable of issuing trays 500 one by one; a tray transfer device 200, including a first tray transfer line 210 arranged along the Y-axis and a transfer platform 220 located below the first tray transfer line 210, the first tray transfer line 210 being used to receive trays 500 issued by the tray issuing device 100 and transfer them to a first position; and a material transfer device 300, including a workpiece conveyor line 310 and a side-pushing mechanism 320, the workpiece conveyor line 310 being arranged along the X-axis, its input end being located at... The first material tray transfer line 210 is located on one side of the X-axis direction, and its output end is connected to the conveyor line of the sandblasting equipment. The tray receiving device 400 is used to collect empty material trays 500. The material tray 500 is provided with at least one storage compartment 510 along the Y-axis direction. Each storage compartment 510 has several workpieces 520 placed side by side along the X-axis direction. When the material tray 500 is moved to the first position, the transfer platform 220 is adapted to lift the material tray 500, and the side pushing mechanism 320 is adapted to push the entire row of workpieces 520 from the material tray 500 into the workpiece conveyor line 310 along the X-axis direction. The transfer platform 220 is also adapted to transfer the empty material tray 500 to the second position and place it in the tray receiving device 400.

[0030] This invention employs the aforementioned structure, using a tray 500 pre-loaded with multiple workpieces 520 as a unit for continuous supply. A side-push mechanism 320 pushes the entire row of workpieces 520 into the workpiece conveyor line 310 in one go, significantly increasing the number of parts fed in a single operation. This breaks through the speed limit of the traditional single-piece gripping and releasing mode, perfectly matching the capacity requirements of high-speed sandblasting conveyor lines and achieving a doubling of production efficiency. Simultaneously, the entire closed-loop automation process, from tray 500 dispensing, transfer positioning, material pushing, to empty tray retrieval, not only completely replaces manual labor, eliminating rhythm fluctuations and quality risks caused by personnel fatigue and operational differences, ensuring stable production rhythm, but also significantly reduces labor costs. Furthermore, the workpieces 520 are transferred in a row within the lifted tray 500 by the side-push mechanism 320, allowing them to flow continuously and closely into the workpiece conveyor line 310. Compared to robotic gripping and releasing, this significantly reduces positioning errors and the risk of collisions and jamming, improving the reliability of the feeding process and further ensuring the continuous and smooth operation of the entire production line.

[0031] Furthermore, referring to Figure 2 As shown, the tray feeding device 100 includes a material frame 110, a material frame lifting module 120, and a tray feeding line 130. The material frame lifting module 120 is connected to the material frame 110 in a transmission manner. The material frame lifting module 120 is a linear module arranged along the Z-axis direction, which can drive the material frame 110 to rise and fall along the Z-axis direction.

[0032] The material frame 110 has open sides on both sides in the Y-axis direction. Multiple sets of support assemblies 140 are spaced apart in the inner cavity of the material frame 110 along the Z-axis direction. Each support assembly 140 includes two support members 141 at the same horizontal height, respectively connected to both sides of the inner cavity of the material frame 110 in the X-axis direction to support the material trays 500. Several material trays 500 can be loaded into the material frame 110 from one of the open sides along the Y-axis direction and correspondingly supported on each support assembly 140. Preferably, in this embodiment, each support assembly 140 can support multiple material trays 500, and the multiple material trays 500 are arranged side-by-side along the Y-axis direction.

[0033] The material tray loading line 130 is a conventional belt conveyor line, arranged along the Y-axis. The material tray loading line 130 passes through the material frame 110, which can rise to its initial position, placing the material tray loading line 130 below the bottom support assembly 140. This facilitates the loading of the material tray 500 into the material frame 110 by operators or robots. The two support members 141 of the support assembly 140 are located outside the material tray loading line 130 in the X-axis direction to prevent the material tray loading line 130 from obstructing the lifting and lowering of the material frame 110. When the material frame 110 is fully loaded with the material tray 500, the material frame lifting module 120 can drive the material frame 110 to descend, so that the bottommost material tray 500 is placed on the material tray loading line 130. The material tray loading line 130 drives the material tray 500 to move out of the material frame 110 from the other open side of the material frame 110 along the Y-axis direction and convey it to the material tray transfer device 200. Then the material frame 110 can continue to descend to continue to place the material tray 500 on the material tray loading line 130.

[0034] Furthermore, referring to Figures 3 to 5 As shown, the input end of the first tray transfer line 210 is connected to the output end of the tray loading line 130 to receive the tray 500 flowing out of the tray loading line 130 and transport it to the first position. The storage compartment 510 has an open side on the side closer to the workpiece conveyor line 310 in the X-axis direction. When the tray 500 moves to the first position, the transfer platform 220 is adapted to lift the tray 500, so that the open side of one of the storage compartments 510 is connected to the input end of the workpiece conveyor line 310. The side pushing mechanism 320 is adapted to push the entire row of workpieces 520 from the tray 500 into the workpiece conveyor line 310 in the X-axis direction, and then the workpiece conveyor line 310 transports the row of workpieces 520 to the conveyor line of the sandblasting equipment. When the tray 500 is provided with multiple storage compartments 510, whenever a workpiece 520 in one storage compartment 510 is pushed away, the transfer platform 220 can drive the tray 500 to move along the Y-axis, so that another storage compartment 510 containing a workpiece 520 can be connected to the workpiece conveyor line 310. After the tray 500 is completely empty, the transfer platform 220 is adapted to transfer the empty tray 500 to a second position and place it in the receiving device 400.

[0035] By adopting the above structure, the workpiece 520 can be efficiently and continuously transported to the conveyor line of the sandblasting equipment, thereby improving the feeding efficiency.

[0036] In the actual cleaning process, only the two sides and top of workpiece 520 in the Y-axis direction need to be cleaned, while the two sides in the X-axis direction do not need to be cleaned. Workpiece 520 is loaded using a side-push method, allowing adjacent workpieces 520 to abut against each other on their X-axis sides, thus avoiding the sandblasting equipment cleaning the X-axis sides of workpiece 520. However, one side of the workpiece 520 at each end in the X-axis direction is not shielded and is still susceptible to over-cleaning.

[0037] Preferably, the first workpiece 520 of the first material tray 500 flowing out in the material frame 110 is replaced with an auxiliary part that has the same outline and size as the workpiece 520, and the last workpiece 520 of the last material tray 500 flowing out is also replaced with an auxiliary part. The auxiliary part can block the sides of the workpieces 520 at both ends in the X-axis direction, so as to prevent the sides of the workpieces 520 at both ends in the X-axis direction from being cleaned.

[0038] Furthermore, the first material tray transfer line 210 is a conventional belt conveyor line, which is provided with a first blocking member 211 at the first position. When the material tray 500 transfers to the first position, the first blocking member 211 can block the material tray 500 and keep it in the first position.

[0039] The transfer platform 220 includes a platform body 221, a transfer module 222, and a platform lifting module 223. The transfer module 222 is a linear module arranged along the Y-axis direction, and its output end is provided with a base 2221. The platform lifting module 223 is disposed on the base 2221 and is a linear cylinder arranged along the Z-axis direction. The platform body 221 is connected to the platform lifting module 223 in a transmission manner. The platform body 221 is adapted to descend along the Z-axis direction under the drive of the platform lifting module 223 so as not to obstruct the flow of the material tray 500 on the first material tray transfer line 210, or to rise along the Z-axis direction to support the material tray 500.

[0040] The platform 221 includes a base plate 2211 and two support bars 2212 connected to the base plate 2211. The support bars 2212 are located on opposite sides of the base plate 2211 along the X-axis. The support bars 2212 extend beyond the base plate 2211 along the conveying direction of the first material tray conveyor line 210. The portion of the support bar 2212 outside the base plate 2211 supports the material tray 500. A second blocking member 2213 is provided at the extended end of the support bar 2212. When the platform 221 rises to support the material tray 500, the second blocking member 2213 can block the material tray 500 in the conveying direction of the first material tray conveyor line 210.

[0041] Furthermore, the workpiece conveyor line 310 is a conventional belt conveyor line, which has first baffles 330 on both sides in the Y-axis direction. The workpiece 520 flowing on the workpiece conveyor line 310 is limited between the first baffles 330 on both sides to ensure that it moves into the conveyor line of the sandblasting equipment in a preset posture.

[0042] The material transfer device 300 includes a width adjustment component 340 that is pulsatorically connected to the first baffle 330. The width adjustment component 340 can drive the first baffles 330 on both sides to move towards or away from each other along the Y-axis to adjust the distance between them and adapt to workpieces 520 of different sizes. The width adjustment component 340 can use a lead screw structure or a cylinder to drive the first baffle 330, which will not be described in detail here.

[0043] The side-pushing mechanism 320 is located above the first material tray conveyor line 210 and includes a side-pushing component 321, a side-pushing module 322, and a first lifting drive component 323. The side-pushing module 322 is a linear module arranged along the X-axis, and the first lifting drive component 323 is a linear cylinder arranged along the Z-axis, which is drivenly connected to the side-pushing module 322. The side-pushing component 321 is drivenly connected to the first lifting drive component 323. When the material tray 500 flows to the first position, the side-pushing component 321 can descend under the drive of the first lifting drive component 323 to correspond to the storage compartment 510. Then, the side-pushing module 322 drives the side-pushing component 321 to move along the X-axis to push the workpiece 520 in the storage compartment 510 into the workpiece conveyor line 310.

[0044] Furthermore, referring to Figure 4 and Figure 6 As shown, the receiving device 400 includes a second tray conveyor line 410 and a first lifting platform 420. The second tray conveyor line 410 is located below the first tray conveyor line 210 and is a belt conveyor line arranged along the Y-axis. The first lifting platform 420 is an electric or pneumatic platform, which is correspondingly located at the second position. When the platform body 221 moves the tray 500 to the second position, the first lifting platform 420 can rise through the clearance area between the two support bars 2212 and support the tray 500 on the platform body 221. After the platform body 221 moves away from the second position, the first lifting platform 420 can lower the tray 500 to place the tray 500 on the second tray conveyor line 410, and then the second tray conveyor line 410 unloads the tray 500.

[0045] In addition, refer to Figures 6 to 8 As shown, the tray receiving device 400 also includes a tray receiving mechanism 430 connected to the output end of the second tray transfer line 410. The tray receiving mechanism 430 is used to receive and stack the trays 500 output by the second tray transfer line 410.

[0046] The closing mechanism 430 includes a frame 431, a roller line 432, a second lifting platform 433, and a closing cart 434. A storage cavity 4311 is formed inside the frame 431, and the roller line 432 is installed near the top of the storage cavity 4311. The roller line 432 is an inclined line with a high end and a low end in the Y-axis direction. The high end of the roller line 432 connects to the output end of the second tray transfer line 410, and the trays 500 flowing into the roller line 432 from the second tray transfer line 410 can move towards the low end of the roller line 432 under gravity. A third blocking member 4327 is provided at the low end of the roller line 432 to block the trays 500 on the roller line 432.

[0047] The roller conveyor 432 includes a base plate 4321, a first conveyor body 4322, a feeding drive 4323, and a second conveyor body 4324. The base plate 4321 is connected to the inner wall of the storage cavity 4311, and the first conveyor body 4322 is disposed on the base plate 4321 for supporting and conveying the tray 500. The first conveyor body 4322 has a high end and a low end, and the high end of the first conveyor body 4322 is connected to the output end of the second tray conveyor line 410. The first conveyor body 4322 includes two sets of first roller assemblies arranged opposite each other along the X-axis direction, and the two sets of first roller assemblies cooperate to support and convey the tray 500.

[0048] The second feed line 4324 has a high end and a low end. The high end of the second feed line 4324 is not higher than the low end of the first feed line 4322 and is connected to the low end of the first feed line 4322. The second feed line 4324 includes two sets of second roller assemblies arranged opposite each other along the X-axis. The two sets of second roller assemblies cooperate to support and rotate the material tray 500.

[0049] Both the first roller assembly and the second roller assembly include a roller plate 4325 and rollers 4326 rotatably spaced on the roller plate 4325. The height of each roller 4326 gradually decreases in the direction from one end of the roller line 432 near the second tray flow line 410 to the other end. A third blocking member 4327 is connected to the substrate 4321. The tray 500 flowing out of the first line 4322 can flow into the second line 4324 and is ultimately blocked by the third blocking member 4327.

[0050] A feeding drive 4323 is disposed on the substrate 4321. It is a linear cylinder arranged along the X-axis. The feeding drive 4323 corresponds one-to-one with the second roller assembly, and the output end of the feeding drive 4323 is connected to the roller plate 4325 of the second roller assembly. The two sets of second roller assemblies can move away from each other along the X-axis under the drive of the feeding drive 4323, so that the tray 500 is disengaged from the second line body 4324, or move closer to each other to support the tray 500. Preferably, the substrate 4321 is provided with a second baffle 4328 on the outer side of the first line body 4322 and the second line body 4324 to limit the tray 500 in the X-axis direction.

[0051] The substrate 4321 has a hollow structure in the area between the two sets of second lines 4324. The second lifting platform 433 is located in the lower area between the two sets of second lines 4324. It can receive the trays 500 that detach from the second lines 4324 and gradually lower them so that the trays 500 gradually stack on the second lifting platform 433. The second lifting platform 433 is an electric lifting platform to ensure its lifting accuracy.

[0052] The storage cavity 4311 is an openable and closable structure. When the storage cavity 4311 is opened, the closing carriage 434 can be pushed into the storage cavity 4311. The closing carriage 434 has a closing frame 4341. The bottom of the closing frame 4341 has a support structure. The top of the closing frame 4341 is open, and its side facing the second lifting platform 433 is also open. After the receiving cart 434 is pushed to the preset position of the storage cavity 4311, the second lifting platform 433 enters the receiving frame 4341 through the side of the receiving frame 4341. The top of the receiving frame 4341 is correspondingly located below the hollow structure. As the second lifting platform 433 descends, the stacked trays 500 on it can gradually move from the top of the receiving frame 4341 into the receiving frame 4341 until the second lifting platform 433 descends to the support structure of the receiving frame 4341. At this time, the receiving cart 434 is fully loaded and can be moved out of the storage cavity 4311 to facilitate the transfer of the trays 500.

[0053] Preferably, a hinge 435, such as a hinge, is provided between the substrate 4321 on the side away from the second tray transfer line 410 in the Y-axis direction and the storage cavity 4311, so that the substrate 4321 can rotate around the X-axis. The roller line 432 also includes an adjustment drive 436, which is a linear cylinder. Its output end is hinged to the substrate 4321, and its main body is hinged to the inner wall of the storage cavity 4311. The adjustment drive 436 can push or pull the substrate 4321 to rotate, so as to adjust the inclination of the roller line 432. When the material tray 500 needs to be transferred, the output end of the drive unit 436 is extended to increase the inclination of the roller line 432, so as to better receive and transfer the material tray 500. When the material tray 500 needs to be lowered to the second lifting platform 433, the output end of the drive unit 436 is retracted to reduce the inclination of the roller line 432, so that the material tray 500 can be placed more stably on the second lifting platform 433.

[0054] The working process of the batch feeding equipment of the present invention is as follows: The tray dispensing device 100 lowers the tray 500 containing the workpieces 520 to be cleaned; the first tray transfer line 210 receives the tray 500 and transfers it to the first position; the transfer platform 220 lifts the tray 500 so that one of the storage compartments 510 of the tray 500 is connected to the input end of the workpiece conveyor line 310; the side pushing mechanism 320 pushes the entire row of workpieces 520 in the storage compartment 510 into the workpiece conveyor line 310; then the transfer platform 220 drives the tray 500 to move slightly so that the other storage compartment 510 is connected to the input end of the workpiece conveyor line 310, so that the side pushing mechanism 320 performs a side pushing operation again until the tray 500 is empty. Then the transfer platform 220 transfers the tray 500 to the second position, while the workpiece conveyor line 310 continues to receive the tray 500; when the empty tray 500 is transferred to the second position... In position two, the first lifting platform 420 rises to support the tray 500, the transfer platform 220 moves back to position one to continue lifting the incoming tray 500, and the first lifting platform 420 descends to place the tray 500 on the second tray transfer line 410; the second tray transfer line 410 drives the tray 500 to the roller line 432, and the tray 500 flows from the high end to the low end of the roller line 432 under the action of gravity; then the second lifting platform 433 rises to the low end of the roller line 432, the roller line 432 releases the tray 500 at the low end, so that the tray 500 is supported by the second lifting platform 433; whenever the second lifting platform 433 receives a tray 500, it descends by the height of one tray 500, so that the trays 500 are gradually stacked on the second lifting platform 433, and placed into the receiving cart 434 under the action of the descending action of the second lifting platform 433.
