Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated component production, and specifically relates to a stacking mechanism for prefabricated components. Background Art

[0002] Prefabricated components refer to concrete products processed and produced in factories in a standardized and mechanized manner. Corresponding traditional cast-in-place concrete requires on-site formwork making, on-site pouring, and on-site curing. In order to reduce the space occupied by prefabricated components and facilitate transportation, prefabricated components are usually stacked using stacking equipment after demolding.

[0003] However, existing stacking equipment for prefabricated components usually stacks by lifting with mechanical claws. Since it is necessary to lift concrete prefabricated component plates, there are certain safety hazards in the operation process. At the same time, high-precision mechanical claws are costly, and the stacking speed is slow. Also, during the transportation of prefabricated components, if the position is offset, it will affect the grasping of the mechanical claws. Summary of the Invention

Detailed implementation manners

[0038] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0039] As Figure 1 , Figure 2 , Figure 6 , Figure 8 , Figure 10 As shown in

[0040] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 10 , Figure 11As shown, the palletizing structure 2 includes a support base 201. The support base 201 is provided at the end of the conveying table 1. A first motor 202 is installed on each side of the support base 201. A driving disk 204 is installed on the output shaft of the first motor 202. A cylindrical structure is provided on the side of the driving disk 204. A lifting arm 205 is rotatably connected to each side of the support base 201. A first sliding groove 206 is formed in the middle of the lifting arm 205. The cylindrical structure on the side of the driving disk 204 is slidably connected to the lifting arm 205 through the first sliding groove 206. A lifting plate 203 is slidably connected to each side of the support base 201. A second sliding groove 207 is formed in the lifting plate 203. The end of the lifting arm 205 is slidably connected to the lifting plate 203 through the second sliding groove 207;

[0041] The cylindrical structure on the side of the driving disk 204 slides in the first sliding groove 206 in the middle of the lifting arm 205, which will cause the lifting arm 205 to swing up and down around the rotating shaft within a certain angle range. The end of the lifting arm 205 slides with the lifting plate 203 through the second sliding groove 207, and finally drives the lifting plate 203 to lift or contract. The cross section of the lifting plate 203 is in a "T" shape. When the prefabricated part is conveyed to the support base 201 and the lifting plate 203 is lifted at the same time, the edge parts of the two lifting plates 203 will lift the prefabricated part to a certain height, and then the lifted prefabricated part is supported and fixed by the support structure 7. The lifting plate 203 falls back at the same time, and then the conveying table 1 continues to convey the prefabricated part until the prefabricated part is moved to the bottom side of the previous prefabricated part. The driving disk 204 continues to rotate and stack the prefabricated parts. Since the lifting height of the prefabricated part is small, the palletizing process is safer and more efficient.

[0042] Specifically, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 10 、 Figure 15 shown, the limiting structure 5 includes limiting side plates 501. A limiting side plate 501 is slidably connected to each side of the support base 201. A first lead screw 502 is rotatably connected to the middle of the support base 201. A threaded block 504 is threadedly connected to the first lead screw 502. A connecting rod 503 is rotatably connected to each side of the threaded block 504. The other end of the connecting rod 503 is rotatably connected to the limiting side plate 501 provided on the same side. A blocking rod 506 is slidably connected to the top side of the support base 201. The blocking rod 506 is in a "T" shape. An adjusting threaded tube 505 is rotatably connected to the support base 201. The end of the blocking rod 506 is threadedly connected to the inside of the adjusting threaded tube 505;

[0043] The limiting side plates 501 located on both sides of the support base 201 can limit both sides of the precast member, improving the stability of palletizing. For precast members of different specifications, during the palletizing operation, the user can rotate the first lead screw 502 at the end of the support base 201. When the first lead screw 502 rotates, it drives the threaded block 504 to move to one side. At the same time, the connecting rods 503 rotating on both sides of the threaded block 504 push or pull the limiting side plates 501 on both sides, thereby realizing the adjustment of the distance between the limiting side plates 501 to adapt to the palletizing of precast members of different widths. At the same time, in order to ensure that the lifting plate 203 can support the middle position of the precast member during the palletizing process, the user can also rotate the adjusting threaded tube 505 according to the length of the precast member to change the position of the end of the blocking rod 506 on the support base 201. When the precast member is conveyed to the support base 201, it will be blocked by the blocking rod 506 to a specified position to ensure the stability when the lifting plate 203 lifts the precast member.

[0044] Specifically, as Figure 4 、 Figure 8 、 Figure 9 、 Figure 15 shown, the support structure 7 includes an inclined surface support rod 701. The side surface of the limiting side plate 501 is slidably connected to the inclined surface support rod 701. The side surface of the inclined surface support rod 701 is an inclined surface structure. A second spring 702 is fixedly connected between the inclined surface support rod 701 and the limiting side plate 501. An inclined groove 703 is formed at the bottom side of the inclined surface support rod 701. A traction rod 704 is slidably connected to the inner side of the limiting side plate 501. The top protrusion of the traction rod 704 is slidably connected to the inclined surface support rod 701 through the inclined groove 703. A driving gear 705 is engaged with the bottom side of the traction rod 704. The driving gear 705 is rotatably connected to the limiting side plate 501. A torsion spring 706 is fixedly connected between the driving gear 705 and the limiting side plate 501;

[0045] After the lifting plate 203 lifts the prefabricated component to a certain height, in order to maintain the height of the current prefabricated component, an inclined surface support rod 701 is provided on the side of the limit side plate 501. When the prefabricated component passes by the inclined surface support rod 701 during the lifting process, due to the effect of the inclined surface, the inclined surface support rod 701 is forced to retract, and the prefabricated component passes over the inclined surface support rod 701. The inclined surface support rod 701 pops up again under the push of the second spring 702 and supports the lifted prefabricated component, so that the lifting plate 203 can lift and stack the next prefabricated component. On the other hand, an inclined groove 703 is opened at the bottom side of the inclined surface support rod 701. After the stacking of the prefabricated components is completed, the user can move the lifting rod to the bottom side of the prefabricated component for support through the motor. At this time, the driving gear 705 is rotated, the driving gear 705 drives the traction rod 704 to slide, and the convex block on the top side of the traction rod 704 can drive the inclined surface support rod 701 to retract through the inclined surface structure. At this time, the entire palletizing can be lowered through the lifting plate 203, which is convenient for transferring and transporting the palletizing.

[0046] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 12 , Figure 13 , Figure 14 shown, the conveying structure 3 includes a driving guide roller 301. One end of the conveying table 1 close to the support seat 201 is rotatably connected with a driving guide roller 301. The conveying table 1 is sequentially and equidistantly rotatably connected with a plurality of driven rollers 303 on the side of the driving guide roller 301. Tooth-shaped grooves are provided at the ends of the driving guide roller 301 and the driven rollers 303. A synchronous belt 304 is sleeved and engaged at the ends of the driving guide roller 301 and the plurality of driven rollers 303. A second motor 302 is installed on the side of the conveying table 1, and the output shaft of the second motor 302 is fixedly connected with the end of the driving guide roller 301 through a coupling;

[0047] When the second motor 302 installed on the side of the conveying table 1 drives the driving guide roller 301 to rotate, by means of the rotation of the synchronous belt 304, all the driven rollers 303 can be driven to rotate synchronously. After the prefabricated component is placed on the conveying table 1, it can be conveyed towards the support seat 201 to perform the palletizing operation.

[0048] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 11As shown in the figure, the connecting structure 4 includes a driving roller 402. Two driving rollers 402 are rotatably connected to the middle of the support base 201. A plurality of support rollers 403 are arranged between the two driving rollers 402. A conveyor belt 401 is sleeved between the two driving rollers 402. The support rollers 403 are in contact with the inner side of the conveyor belt 401. The surface of the conveyor belt 401 is horizontally tangent to the driving guide roller 301. One connecting block 409 is fixedly connected to each side of the conveying table 1. An opening is provided at the end of the connecting block 409. One clamping block 410 is slidably connected to each side of the support base 201. A first spring 411 is fixedly connected between the clamping block 410 and the support base 201. The end of the clamping block 410 is engaged with the end of the connecting block 409 through the opening. A second toothed ring 406 is fixedly connected to each end of the driving roller 402. A first toothed ring 404 is fixedly connected to each side of the driving guide roller 301. A reversing gear 405 is meshed between the first toothed ring 404 and the second toothed ring 406. The reversing gear 405 is rotatably connected to the support base 201. A release rod 407 passes through the middle of the driving roller 402. The two ends of the release rod 407 are rotatably connected to both sides of the support base 201. A receiving hole 408 is provided at the end of the release rod 407. A hemispherical protrusion is provided on the side of the clamping block 410. The protrusion structure on the side of the clamping block 410 is in contact with the release rod 407 through the receiving hole 408;

[0049] In order to facilitate the transfer of the prefabricated parts from the conveying table 1 to the support base 201, the conveying table 1 and the support base 201 can be quickly connected. A pulley structure is provided at the bottom side of the support base 201 for convenient movement. During operation, the user needs to move the support base 201 to the end of the conveying table 1 and slide the end of the support base 201 between the connecting blocks 409 on both sides. At this time, the clamping block 410 will be engaged with the clamping block 410 arranged on the side of the support base 201. With the connection between the support base 201 and the conveying table 1, the reversing gear 405 at the end of the support base 201 will be engaged with the first toothed ring 404 on the driving guide roller 301. Thus, when the conveying table 1 starts to convey the prefabricated parts, the driving guide roller 301 will drive the driving roller 402 to rotate through the reversing gear 405 and the second toothed ring 406 at the same time, and the driving roller 402 will further drive the conveyor belt 401 to rotate, so that the prefabricated parts will continue to move at the same speed after being conveyed to the support base 201 until they are in contact with the blocking rod 506, and finally are lifted and stacked. On the other hand, after the palletizing work is completed, the user can rotate the release rod 407, so that the hemispherical protrusion on the side of the clamping block 410 disengages from the receiving hole 408 on the release rod 407. At this time, the clamping block 410 retracts and releases the engagement state with the connecting block 409. At this time, the support base 201 can be separated from the conveying table 1 to unload the prefabricated part palletizing.

[0050] Specifically, as Figure 1 , Figure 12 , Figure 13 , Figure 14 shown, the guiding structure 6 includes a mounting rod 601. One mounting rod 601 is rotatably connected to each side of the conveying table 1. A guiding wheel 602 is rotatably connected to the end of the mounting rod 601. A tooth groove 603 is formed on the bottom side of the guiding wheel 602. The guiding wheel 602 meshes with a first bevel gear 604 through the tooth groove 603. The first bevel gear 604 is rotatably connected to the mounting rod 601. A second bevel gear 605 meshes with the side surface of the first bevel gear 604. The second bevel gear 605 is fixedly connected to the end of the corresponding driven roller 303. A resisting rod 606 is vertically and fixedly connected to the bottom end of the mounting rod 601. A limiting groove 607 is formed in each side inside the conveying table 1. The conveying table 1 is slidably connected with a threaded slider 608 through the limiting groove 607. The end of the threaded slider 608 is slidably connected to the side surface of the resisting rod 606. A second lead screw 609 is rotatably connected to the middle of the conveying table 1. The thread directions on both sides of the second lead screw 609 are opposite. The two sides of the second lead screw 609 are respectively threadedly connected to the threaded sliders 608 arranged on the same side;

[0051] In order to ensure that the prefabricated parts are arranged neatly while moving on the conveying table 1, a guiding wheel 602 is provided on each side of the conveying table 1. The guiding wheel 602 is rotatably connected to the mounting rod 601. The mounting rod 601 can rotate with respect to the conveying table 1. When the driven roller 303 rotates, the guiding wheel 602 will be driven to rotate through the first bevel gear 604 and the second bevel gear 605. In this way, when the prefabricated parts pass between the guiding wheels 602 on both sides, the rotating guiding wheels 602 will adjust the placement positions of the prefabricated parts to ensure subsequent neat stacking. On the other hand, for prefabricated parts of different widths, the user can rotate the second lead screw 609, so that the positions of the threaded sliders 608 on both sides of the second lead screw 609 change. Due to the resisting effect of the threaded sliders 608, the maximum rotation angle of the mounting rod 601 will change. Through the rotation effect of the driving roller 402, the mounting rod 601 will automatically rotate to the maximum rotation angle, thereby realizing the adjustment of the distance between the two guiding wheels 602 and making the use more flexible.

[0052] When the present invention is in use, first, in order to ensure the safety, stability and efficiency during the palletizing process of prefabricated components, the palletizing structure 2 stacks the prefabricated components in a bottom-side stacking manner. During use, the support base 201 is moved to the end of the conveying table 1 through the pulleys at the bottom of the support base 201. As the prefabricated components are conveyed onto the support base 201, the first motors 202 on both sides of the support base 201 are electrically connected to an external power source and started simultaneously. At this time, the first motors 202 drive the driving disks 204 to start rotating. Since the right end of the lifting arm 205 is rotatably connected to the support base 201 through a rotating shaft, and the columnar structure on the side of the driving disk 204 slides in the first chute 206 in the middle of the lifting arm 205, the lifting arm 205 will swing up and down around the rotating shaft within a certain angle range. The end of the lifting arm 205 slides through the second chute 207 with the lifting plate 203, and finally drives the lifting plate 203 to lift or contract. The cross-section of the lifting plate 203 is in a "T" shape. When the prefabricated components are conveyed onto the support base 201 and the lifting plate 203 is lifted at the same time, the edge parts of the two lifting plates 203 will lift the prefabricated components to a certain height, and then the lifted prefabricated components are supported and fixed by the support structure 7. The lifting plate 203 falls back at the same time, and then the conveying table 1 continues to convey the prefabricated components until the prefabricated components are moved to the bottom side of the previous prefabricated component. The driving disk 204 continues to rotate and stacks the prefabricated components. Since the lifting height of the prefabricated components is small, the palletizing process is safer and more efficient. The limit side plates 501 located on both sides of the support base 201 can limit the two sides of the prefabricated components and improve the stability of palletizing. For prefabricated components of different specifications, during the palletizing operation, the user can rotate the first lead screw 502 at the end of the support base 201. When the first lead screw 502 rotates, it will drive the threaded block 504 to move to one side, and at the same time, the connecting rods 503 rotating on both sides of the threaded block 504 will push or pull the two limit side plates 501, thereby realizing the adjustment of the distance between the limit side plates 501 to adapt to the palletizing of prefabricated components of different widths. At the same time, in order to ensure that the lifting plate 203 can support the middle position of the prefabricated component during the palletizing process, the user can also rotate the adjusting threaded tube 505 according to the length of the prefabricated component to change the position of the end of the blocking rod 506 on the support base 201. When the prefabricated component is conveyed onto the support base 201, it will be blocked by the blocking rod 506 to a specified position to ensure the stability when the lifting plate 203 lifts the prefabricated component.After the lifting plate 203 lifts the prefabricated component to a certain height, in order to maintain the height of the current prefabricated component, an inclined surface support rod 701 is provided on the side of the limit side plate 501. When the prefabricated component passes by the inclined surface support rod 701 during the lifting process, due to the effect of the inclined surface, the inclined surface support rod 701 is forced to retract, and the prefabricated component passes over the inclined surface support rod 701. The inclined surface support rod 701 pops out again under the push of the second spring 702 and supports the lifted prefabricated component, so that the lifting plate 203 can lift and stack the next prefabricated component. On the other hand, an inclined groove 703 is provided at the bottom side of the inclined surface support rod 701. When the stacking of the prefabricated components is completed, the user can move the lifting rod to the bottom side of the prefabricated component for support through the motor. At this time, the driving gear 705 is rotated, the driving gear 705 drives the traction rod 704 to slide, and the convex block on the top side of the traction rod 704 can drive the inclined surface support rod 701 to retract through the inclined surface structure. At this time, the entire pallet can be lowered through the lifting plate 203, which is convenient for transferring and transporting the pallet. A second motor 302 is installed on the side of the conveying table 1. While the second motor 302 drives the driving guide roller 301 to rotate, through the rotation of the synchronous belt 304, all the driven rollers 303 can be driven to rotate synchronously. After placing the prefabricated component on the conveying table 1, it can be conveyed in the direction of the support seat 201 to perform the palletizing operation. In order to facilitate the transfer of the prefabricated component from the conveying table 1 to the support seat 201, the conveying table 1 and the support seat 201 can be quickly connected. A pulley structure is provided at the bottom side of the support seat 201 for convenient movement. During operation, the user needs to move the support seat 201 to the end of the conveying table 1 and slide the end of the support seat 201 between the connecting blocks 409 on both sides. At this time, the clamping block 410 will engage with the clamping block 410 provided on the side of the support seat 201. With the connection between the support seat 201 and the conveying table 1, the reversing gear 405 at the end of the support seat 201 will engage with the first tooth ring 404 on the driving guide roller 301. Thus, when the conveying table 1 starts to convey the prefabricated component, the driving guide roller 301 will drive the transmission roller 402 to rotate through the reversing gear 405 and the second tooth ring 406 at the same time, and the transmission roller 402 will further drive the conveyor belt 401 to rotate, so that after the prefabricated component is conveyed to the support seat 201, it will continue to move at the same speed until it abuts against the blocking rod 506, and finally is lifted and stacked. On the other hand, after the palletizing work is completed, the user can rotate the release rod 407, so that the hemispherical protrusion on the side of the clamping block 410 disengages from the receiving hole 408 on the release rod 407. At this time, the clamping block 410 retracts and releases the clamping state with the connecting block 409. At this time, the support seat 201 can be separated from the conveying table 1 to unload the prefabricated component pallet.In order to ensure that the preforms are arranged neatly while moving on the conveyor 1, a guide wheel 602 is provided on both sides of the conveyor 1. The guide wheel 602 is rotatably connected to the mounting rod 601. The mounting rod 601 and the conveyor 1 can rotate. When the driven roller 303 rotates, the guide wheel 602 is driven to rotate through the first bevel gear 604 and the second bevel gear 605. In this way, when the preforms pass between the guide wheels 602 on both sides, the rotating guide wheels 602 will adjust the placement of the preforms to ensure that the subsequent stacking is neat. On the other hand, for preforms of different widths, the user can rotate the second screw rod 609 to change the position of the threaded sliders 608 on both sides of the second screw rod 609. Due to the interference of the threaded slider 608, the maximum rotation angle of the mounting rod 601 will change, and through the rotation effect of the transmission roller 402, the mounting rod 601 will automatically rotate to the maximum rotation angle, so that the distance between the two guide wheels 602 can be adjusted, making the use more flexible.
