Description

Technical Field

[0001] This invention relates to the field of steel strand production technology, specifically to an automatic material stacking device for pads. Background Technology

[0002] Steel strand is a steel product made of multiple steel wires twisted together. The surface of carbon steel can be coated with zinc, zinc-aluminum alloy, aluminum, copper, epoxy resin, etc., as needed. During the production process, steel strand needs to be protected by padding.

[0003] In the current production process, the pallets are dropped one by one onto the ground, requiring manual sorting and counting, which consumes a lot of time and manpower, resulting in low production efficiency. Moreover, the pallets often overlap during transportation, causing transportation chaos and affecting production efficiency.

[0004] To address the aforementioned shortcomings, a technical solution is provided. Summary of the Invention

[0005] The technical problem to be solved by this invention is as follows:

[0006] In the current production process, the pallets are dropped one by one onto the ground, requiring manual sorting and counting, which consumes a lot of time and manpower, resulting in low production efficiency. Moreover, the pallets often overlap during transportation, causing transportation chaos and affecting production efficiency.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] An automatic pallet stacking device includes symmetrically arranged support plates. Conveying components for conveying pallets are symmetrically arranged on opposite sides of the two support plates. A separating component for controlling the spacing between the two conveying components is arranged between them. A collecting component for collecting pallets is arranged on one side of each conveying component. A counting component for counting pallets is arranged between the conveying component and the collecting component.

[0009] The separating assembly includes a separating box located below a pad, with an opening at the top of the separating box. A lifting plate is slidably arranged inside the separating box, with an opening extending through the middle of the lifting plate. Separating rollers are rotatably arranged in the middle of the lifting plate via several rotating shafts, with the rotating speeds of the several separating rollers being different. A driving mechanism for driving the separating rollers to rotate is provided on the lifting plate.

[0010] Furthermore, an adjusting cylinder and a positioning cylinder are fixedly installed on the side of the support plate away from the conveying component. The output end of the adjusting cylinder is fixedly connected to the conveying component, and the output end of the positioning cylinder passes through the support plate and is fixedly installed with a positioning plate.

[0011] Furthermore, the conveying assembly includes a conveying platform, with conveying gears rotatably mounted at both ends of one side of the conveying platform. A conveying chain meshes between the two conveying gears, and conveying plates are fixedly mounted on the surface of the conveying chain. A conveying motor is fixedly mounted on one side of the conveying platform, and the output end of the conveying motor is fixedly connected to one of the conveying gears.

[0012] Furthermore, a number of guide wheels are fixedly installed on the top of the conveyor platform, and a number of tension wheels are fixedly installed on the bottom of the conveyor platform. Both the guide wheels and the tension wheels mesh with the inner side of the conveyor chain.

[0013] Furthermore, the driving mechanism includes several driving gears fixedly disposed on the outside of corresponding rotating shafts, and a transmission gear meshing between adjacent driving gears. The transmission gear is rotatably disposed on the lifting plate. The diameters of the driving gears and the transmission gears are all different. A driving motor is fixedly disposed on the lifting plate, and the output end of the driving motor is fixedly connected to one of the rotating shafts.

[0014] Furthermore, the bottom of the lifting plate is provided with a lifting mechanism for driving the lifting plate to rise and fall. The lifting mechanism includes lifting cylinders symmetrically fixed inside the partition box. A sliding plate is fixedly provided at the output end of the lifting cylinder. A lifting shaft is hinged between the sliding plate and the lifting plate.

[0015] Furthermore, the material collection assembly includes a rotatable material collection plate, the bottom of which is provided with a rotating mechanism for driving the material collection plate to rotate, and a plurality of material collection seats are fixedly provided on the top of the material collection plate. The plurality of material collection seats are arranged in a circular array on the top of the material collection plate. The top of the material collection seat is provided with an opening, and the material collection seat is provided with a storage mechanism for closing the top of the material collection seat.

[0016] Furthermore, the rotating mechanism includes a base disposed below the collecting plate, the collecting plate being rotatably mounted on the base, and a rotating motor being fixedly disposed inside the base for driving the collecting plate to rotate on the base.

[0017] Furthermore, the storage mechanism includes a storage plate slidably disposed on one side of the material collection seat, a rack fixedly disposed on one side of the storage plate, a storage motor disposed on the material collection seat, and a storage gear meshing with the rack fixedly disposed at the output end of the storage motor.

[0018] Furthermore, the counting component includes a laser emitter located at the top, and a laser receiver disposed below the laser emitter. The laser emitter and the laser receiver are symmetrically arranged vertically about the conveying component as an axis. The counting component is electrically connected to the rotating mechanism and the storage mechanism.

[0019] The beneficial effects of this invention are:

[0020] In this invention, the separation component allows the lifting cylinder to control the movement of the sliding plate, which, in conjunction with the lifting shaft, drives the lifting plate to rise and fall within the separation box. This causes several separating rollers to rise and fall, contacting the bottom of the corresponding pads. A drive motor controls one of the rotating shafts to rotate, which, in conjunction with several drive gears and transmission gears, drives several rotating shafts to rotate synchronously, thus achieving synchronous rotation of the separating rollers. Since the diameters of the drive gears and transmission gears are different, the rotation speeds of the separating rollers are different, and the rotation direction of the separating rollers is opposite to the conveying direction of the pads. This causes the separating rollers to slow down the corresponding pads, resulting in different conveying speeds of the pads on the conveying component. This creates a certain gap between the pads, which on the one hand prevents material overlap and ensures that the pads are conveyed in an orderly manner, and on the other hand facilitates automatic counting of the pads later, improving production efficiency.

[0021] By configuring the material collection component and the counting component, the pad moves between the laser emitter and the laser receiver during the conveying and unloading process. The laser emitted by the laser emitter is interrupted by the laser receiver, and the counting component counts once. When the number of pads counted reaches a preset quantity, the counting component controls the rotating motor to drive the material collection plate to rotate, thereby replacing it with another material collection seat for storage. The counting component simultaneously controls the receiving motor to drive the receiving gear to rotate, which in turn engages with the rack to drive the receiving plate to extend and close the top of the material collection seat, realizing the storage and preservation of the pad. It also realizes automatic counting and material collection of the pads, improving production efficiency and saving production time. The setting of the separator component makes the counting component count more accurate, improving production efficiency. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-9 The present invention provides a technical solution:

[0035] An automatic pallet stacking device includes symmetrically arranged support plates 1. Conveying components 2 for conveying pallets are symmetrically arranged on opposite sides of the two support plates 1. The distance between the two conveying components 2 is adjustable to convey pallets of different specifications. A separating component 3 for controlling the distance between the pallets is arranged between the two conveying components 2. A collecting component 4 for collecting pallets is arranged on one side of each conveying component 2. A counting component 5 for counting pallets is arranged between the conveying component 2 and the collecting component 4.

[0036] Please see Figure 3An adjusting cylinder 101 and a positioning cylinder 102 are fixedly installed on the side of the support plate 1 away from the conveying assembly 2. The output end of the adjusting cylinder 101 is fixedly connected to the conveying assembly 2, and the output end of the positioning cylinder 102 passes through the support plate 1 and is fixedly installed with a positioning plate 103. The positioning plate 103 is used to limit the pads conveyed on the conveying assembly 2, thereby ensuring the accurate conveying path of the pads and preventing the pads from slipping off the conveying assembly 2. The setting of two adjusting cylinders 101 allows the distance between the two conveying assemblies 2 to be adjusted. Combined with the positioning cylinder 102 controlling the distance between the two positioning plates 103, the conveying assembly 2 can meet the conveying requirements of pads of different specifications, thereby improving the applicability of the device.

[0037] Please see Figure 4 The conveying assembly 2 includes a conveying platform 201. Conveying gears 202 are rotatably mounted at both ends of one side of the conveying platform 201. A conveying chain 203 meshes between the two conveying gears 202. Conveying plates are fixedly mounted on the surface of the conveying chain 203. The conveying plates are used to convey the pads. A conveying motor 204 is fixedly mounted on one side of the conveying platform 201. The output end of the conveying motor 204 is fixedly connected to one of the conveying gears 202.

[0038] The top of the conveyor platform 201 is fixedly equipped with several guide wheels 205, and the bottom of the conveyor platform 201 is fixedly equipped with several tension wheels 206. Both the guide wheels 205 and the tension wheels 206 mesh with the inner side of the conveyor chain 203. Through the arrangement of the conveyor assembly 2, the conveyor motor 204 drives one of the conveyor gears 202 to rotate, which in turn drives the conveyor chain 203 to move. The two ends of the pad are respectively placed on the two conveyor chains 203 on both sides, thus completing the conveying process of the pad. The guide wheels 205 are used to support and guide the conveying of the pad, and the tension wheels 206 are used to ensure the tension of the conveyor chain 203 and improve the conveying stability.

[0039] Please see Figures 5-6 The separating assembly 3 includes a separating box 301 located below the pad. The top of the separating box 301 has an opening, and a lifting plate 302 is slidably disposed inside the separating box 301. The lifting plate 302 has an opening through its middle section, and separating rollers 303 are rotatably disposed on the middle section of the lifting plate 302 via several rotating shafts. The rotating speeds of the separating rollers 303 are different, and a driving mechanism for driving the rotating separating rollers 303 is provided on the lifting plate 302. The rotation direction of the separating rollers 303 is opposite to the conveying direction of the pad. By having several separating rollers 303 contact several pads, the corresponding pads are slowed down, resulting in different conveying speeds of the several pads on the conveying assembly 2, thus creating gaps between the several pads.

[0040] The driving mechanism includes several driving gears 304 fixedly mounted on the outside of corresponding rotating shafts. Adjacent driving gears 304 are meshed with transmission gears 305. The transmission gears 305 are rotatably mounted on the lifting plate 302. The diameters of the driving gears 304 and the transmission gears 305 are all different, thereby ensuring that the rotation speed of each rotating shaft is different. A driving motor 306 is fixedly mounted on the lifting plate 302, and the output end of the driving motor 306 is fixedly connected to one of the rotating shafts.

[0041] The bottom of the lifting plate 302 is provided with a lifting mechanism for driving the lifting plate 302 to rise and fall. The lifting mechanism includes lifting cylinders 307 symmetrically fixed inside the partition box 301. A sliding plate is fixedly provided at the output end of the lifting cylinder 307. A lifting shaft 308 is hinged between the sliding plate and the lifting plate 302. The lifting mechanism can drive several partition rollers 303 to rise and fall so that they contact the bottom of the pad. The separation component 3 controls the movement of the sliding plate via the lifting cylinder 307, which in turn drives the lifting plate 302 to rise and fall within the separation box 301 via the lifting shaft 308. This causes the separation rollers 303 to rise and fall, contacting the bottom of the corresponding pads. The drive motor 306 controls one of the rotating shafts to rotate, which in turn drives the rotating shafts to rotate synchronously via the drive gears 304 and transmission gears 305. This results in the synchronous rotation of the separation rollers 303. Since the diameters of the drive gears 304 and transmission gears 305 are different, the rotation speeds of the separation rollers 303 are different. Furthermore, the rotation direction of the separation rollers 303 is opposite to the conveying direction of the pads, causing the separation rollers 303 to slow down the corresponding pads. This results in different conveying speeds of the pads on the conveying component 2, creating a certain gap between the pads. This helps to prevent material overlap and ensures that the pads are conveyed in an orderly manner. It also facilitates automatic counting of the pads later, improving production efficiency.

[0042] Please see Figures 7-9 The material collection assembly 4 includes a rotatable material collection plate 401. A rotating mechanism for driving the material collection plate 401 to rotate is provided at the bottom of the material collection plate 401. A plurality of material collection seats 402 are fixedly provided on the top of the material collection plate 401, arranged in a circular array on the top of the material collection plate 401. Each material collection seat 402 has an opening at its top and a storage mechanism for closing its top.

[0043] The rotating mechanism includes a base 403 disposed below the collecting plate 401. The collecting plate 401 is rotatably disposed on the base 403. A rotating motor 404 is fixedly disposed inside the base 403. The rotating motor 404 is used to drive the collecting plate 401 to rotate on the base 403.

[0044] The storage mechanism includes a storage plate 405 slidably disposed on one side of the material collection seat 402, a rack 406 fixedly disposed on one side of the storage plate 405, a storage motor disposed on the material collection seat 402, and a storage gear 407 meshing with the rack 406 fixedly disposed at the output end of the storage motor.

[0045] Please see Figure 2 The counting component 5 includes a laser emitter 501 located at the top, and a laser receiver 502 disposed below the laser emitter 501. The laser emitter 501 and the laser receiver 502 are symmetrically arranged vertically about the conveying component 2. The counting component 5 is electrically connected to the rotating mechanism and the storage mechanism. By setting up the material collection component 4 and the counting component 5, the pads move between the laser emitter 501 and the laser receiver 502 during the conveying and feeding process. The laser emitted by the laser emitter 501 is interrupted by the laser receiver 502, and the counting component 5 counts once. When the number of pads reaches the preset number (usually ten in a group), the counting component 5 controls the rotating motor 404 to drive the material collection plate 401 to rotate, thereby replacing it with another material collection seat 402 for storage. The counting component 5 synchronously controls the receiving motor to drive the receiving gear 407 to rotate, thereby cooperating with the rack 406 to drive the receiving plate 405 to extend and close the top of the material collection seat 402, realizing the storage and preservation of the pads. It also realizes the automatic counting and material collection operation of the pads, improving production efficiency and saving production time. The setting of the separator component 3 makes the counting component 5 count more accurately, improving production efficiency.

[0046] Working principle:

[0047] In use, the present invention controls the spacing between two conveying components 2 by symmetrically arranged adjusting cylinders 101 to meet the size requirements of the pads, places several pads on the conveying components 2, and controls the positioning plate 103 to limit the pads by positioning cylinder 102. The conveying motor 204 drives one of the conveying gears 202 to rotate, which in turn drives the conveying chain 203 to move in conjunction with the other conveying gear 202, thereby conveying the pads.

[0048] During the pallet conveying process, the sliding plate is moved by the lifting cylinder 307, which, together with the lifting shaft 308, drives the lifting plate 302 to rise and fall within the separator box 301. This causes several separator rollers 303 to rise and fall, thus contacting the bottom of the corresponding pallets. The drive motor 306 controls one of the rotating shafts to rotate, which, together with several drive gears 304 and transmission gears 305, drives several rotating shafts to rotate synchronously, thereby achieving synchronous rotation of several separator rollers 303. Since the diameters of several drive gears 304 and transmission gears 305 are different, the rotation speeds of several separator rollers 303 are different, and the rotation direction of the separator rollers 303 is opposite to the conveying direction of the pallets. This causes several separator rollers 303 to slow down the corresponding pallets, resulting in different conveying speeds of several pallets on the conveying assembly 2, thus creating a certain gap between several pallets.

[0049] During the material feeding process, the pad moves between the laser emitter 501 and the laser receiver 502. The laser emitted by the laser emitter 501 is interrupted by the laser receiver 502, and the counting component 5 counts once. When the number of pads reaches the preset number (usually ten in a group), the counting component 5 controls the rotating motor 404 to drive the collecting plate 401 to rotate, thereby replacing it with another collecting seat 402 for material storage. The counting component 5 simultaneously controls the receiving motor to drive the receiving gear 407 to rotate, thereby cooperating with the rack 406 to drive the receiving plate 405 to extend and close the top of the collecting seat 402, realizing the storage and preservation of the pad.

[0050] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
