Description

Technical Field

[0001] The invention relates to the technical field of expansion anchor sleeve screening and conveying equipment, in particular to expansion anchor sleeve screening and conveying equipment. Background Art

[0002] Expansion anchor bolts are a commonly used fastener, generally including structures such as anchor rods, sleeves, washers and nuts. The assembly of expansion anchor bolts mostly relies on imaging equipment or infrared detection equipment to identify them, and then the anchor rod or sleeve is rotated to the same position by a manipulator to facilitate the insertion of the anchor rod into the sleeve and ensure correct installation.

[0003] Therefore, in the detection and identification of the anchor sleeve, the sleeve may deflect, making the cross opening position unstable, so that the monitoring of the imaging device may be erroneous, causing the sleeve to be transported in reverse to the subsequent assembly equipment, making it impossible to use the anchor after the reverse sleeve is assembled normally. The present invention aims to complete the positive and negative screening of the sleeve and transport it through a mechanical mechanism.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention

[0005] Based on this, it is necessary to provide an expansion anchor sleeve screening and conveying equipment to address the above technical problems.

[0006] In order to achieve the above object, the present invention provides an expansion anchor sleeve screening and conveying device, comprising: frame; The feeding mechanism includes a feeding machine and a conveyor. The feeding machine is arranged on one side of the frame, the conveyor is installed on the frame, and the output end of the feeding machine is connected to the conveyor; The pressing mechanism comprises a first linear actuator, a pressing shell, a spring 1, a hinge plate, a telescopic support rod, a spring 2, a rotating shaft, a plug rod, a receiving plate, a discharging frame, a half gear 1, a half gear 2 and a pushing mechanism, wherein the first linear actuator is mounted on the frame, the output end of the first linear actuator is slidably connected with the pressing shell, a spring 1 is installed in the pressing shell, the output end of the spring 1 abuts against the first linear actuator, a hinge plate is hinged on the frame, a telescopic support rod is hinged on the frame, a spring 2 is installed in the telescopic support rod, a rotating shaft is rotatably mounted on the frame, a plug rod is installed on the rotating shaft, the receiving plate and the discharging frame are both mounted on the frame, the rotating shaft is located between the receiving plate and the discharging frame, a half gear 1 is installed on the hinge plate, a half gear 2 is installed on the rotating shaft, and the pushing mechanism is mounted on the hinge plate; The rotating mechanism includes a turntable, a through slot, a rotating block, a clamping block, a gear, a rack, a push plate, a spring three, a first rotating drive device, an opening and a second discharging rack. The turntable is rotatably installed on the frame. The turntable is provided with a plurality of through slots matched with the diameter of the sleeve. A rotating block is rotatably installed in the through slot. A clamping block matched with the cross opening of the sleeve is installed on the rotating block. A gear is installed on the rotating block. The rack is installed on the lower pressure shell. The gear and the rack are meshed and connected. A push plate is slidably clamped in the through slot. A spring three is installed on the rotating block. The output end of the spring three is connected with the push plate. The first rotating drive device is installed on the frame. The output end of the first rotating drive device is transmission-connected to the turntable. The opening is provided on the frame. The second discharging rack is installed on the frame.

[0007] By adopting the above technical solution, the sleeve is pushed down and laid flat by the loader to be loaded onto the conveyor for transportation. When the sleeve is transported to the turntable, it will abut against the turntable and stop moving forward, and the conveyor will not stop working. If the opening direction of the sleeve abutting against the turntable is in the opposite direction of the turntable at this time, the first linear actuator can be driven to press down to generate pressure on the sleeve, thereby driving the hinge plate under the sleeve to rotate, so that the hinge plate rotates to abut against the receiving plate, so that the sleeve can slide downward along the receiving plate under the push of the pushing mechanism, and when the hinge plate rotates, the half gear one installed thereon can rotate with it, so that through the meshing of the half gear one and the half gear two, the rotating shaft can drive the plug rod to rotate toward the receiving plate. When the push mechanism pushes the sleeve down, the hollow sleeve can be directly inserted into the insertion rod. After that, the first linear actuator moves up and resets relatively slowly. At the same time, under the support of the spring two in the telescopic support rod, the hinge plate can be reset. At this time, through the meshing of the half gear one and the half gear two, the sleeve on the insertion rod can be driven by the rotating shaft to turn to the side facing the discharge rack. At this time, under the influence of the sleeve's own gravity, the sleeve can slide out along the discharge rack. Therefore, the first linear actuator is continuously pressed down and reset, so that the sleeve with the opening opposite to the direction of the turntable can be continuously output from the discharge rack; when the opening direction of the sleeve abutting the turntable is facing the turntable, the first linear actuator is still slowly descending a fixed length, and the lower pressure shell at its output end will descend together, from The first linear actuator that continues to press down will only squeeze the spring in the lower pressure shell to make it contract, but will not generate greater pressure on the squeezed next sleeve. After the first linear actuator is pressed down and reset, the first rotary drive device starts to drive the turntable to rotate at a suitable angle. At this time, the squeezing of the subsequent sleeve The sleeve is pressed into the through slot and can be smoothly rotated out of the opening on the frame. During the rotation process, the sleeve in the through slot is first squeezed and limited by the subsequent sleeve and then limited by the frame at the opening. Only after the sleeve is completely rotated out of the frame will the spring three in the compressed state drive the push plate to push the sleeve out. At this time, the sleeve can fall on the discharge rack two and be continuously output; when the first linear actuator is pressed down and reset, the sleeve opening may have been stuck in the block, and the rotating block can drive the sleeve to rotate together at this time; when the rotating block rotates to make the sleeve opening stuck in the block, the push plate is supported by the spring three and is in the same plane as the outermost end of the block, thereby preventing the sleeve from bending the rotating block; the opening is small, and only the sleeve stuck in the through slot can be rotated and screwed out;When the first linear actuator is moving downward, the lower pressure shell will abut against the subsequent sleeve to limit the position; the conveyor is always running, and through friction, the sleeves on it all produce pressure on the sleeve abutting the turntable, so that the sleeve can smoothly compress the spring three connected to the push plate; spring one and spring two can be special springs, such as high-carbon steel springs, and the height position of the receiving plate can be set so that the hinge plate can be bent at a smaller angle to complete the work, thereby reducing the loss of spring one and spring two. ;

[0008] Optionally, the pushing mechanism includes a roller, a second rotary drive device and a transmission assembly, the rotating device on the upper surface of the hinged plate has a plurality of rollers, the second rotary drive device is transmission-connected to one of the rollers, and the rollers are transmission-connected to each other through the transmission assembly.

[0009] By adopting the above technical solution, by setting the roller with a larger diameter, it is made flush with the conveyor, which facilitates the installation of the second rotary drive device, and can also be connected to one of the rollers through the transmission component through the output end of the second rotary drive device; the second rotary drive device drives all or several rollers to rotate at intervals through the transmission component, thereby driving the sleeve squeezed by the lower pressure shell and the hinged plate to slide out.

[0010] Optionally, a connecting plate is installed on the frame, the connecting plate is located on the side of the conveyor away from the loader, and the connecting plate is provided with a chamfer.

[0011] By adopting the above technical solution, through the setting of the connecting plate and the chamfer on it, the transport sleeve on the conveyor can slide smoothly onto the connecting plate.

[0012] Optionally, an arc-shaped guide block is installed at the bottom of the connecting plate, and the arc-shaped guide block is used to limit the sleeve sleeved on the insertion rod.

[0013] By adopting the above technical solution, when the sleeve slides out of the hinge plate, the hinge plate will be driven by the compressed spring 2 to instantly rotate at a large angle. Even if the rotating shaft rotates faster, at this time, only a part of the sleeve may be inserted into the insertion rod. Therefore, through the setting of the arc-shaped guide block, the sleeve that slides outward under the centrifugal force on the insertion rod can be limited by the arc-shaped guide block, continue to stay on the insertion rod and slide back to the insertion rod by its own gravity. After that, when the insertion rod rotates to the discharge rack, the sleeve can also be limited so that it will not slide down prematurely.

[0014] Optionally, the hinged plate is provided with rounded corners, and the receiving plate and the arc-shaped guide block are provided with rounded corners.

[0015] By adopting the above technical solution, the rotation of the hinged plate and its abutment with the receiving plate are facilitated, and the rounded corners on the arc-shaped guide block can limit the sleeve and prevent it from sliding down prematurely.

[0016] Optionally, a plurality of rollers 2 are rotatably mounted on the lower pressure shell, and the rollers 2 are matched with the rollers.

[0017] By adopting the above technical solution, the roller 2 cooperates with the roller to clamp the drum, so that when the pushing mechanism pushes the sleeve to slide down, the friction between the sleeve and the lower pressure shell can be reduced.

[0018] Optionally, the frame is provided with a card slot, a connecting frame is slidably connected in the card slot, and the rack is installed on the lower pressure shell through the connecting frame.

[0019] By adopting the above technical solution, when the lower pressure shell moves downward, the rack can be driven to move together through the connecting frame, and the connecting frame is slidably engaged in the slot, so that when the lower pressure shell is pressed downward, the thrust of the subsequent sleeve on it can be balanced to protect the first linear actuator.

[0020] Optionally, blocks are installed on both sides of the connecting frame, and the blocks are in contact with the frame.

[0021] By adopting the above technical solution, the sliding engagement of the connecting frame in the engagement slot is achieved through the abutment between the engagement block and the frame.

[0022] This technical solution has at least the following beneficial effects: The hinge plate is driven to deflect by the first linear actuator, so that the sleeve that is not stuck in the turntable, that is, the sleeve with the opening facing the opposite side of the turntable can be pressed down and transported to the receiving plate, and through the meshing of the half gear 1 and the half gear 2, the sleeve on the receiving plate can be driven by the insertion rod to flip and then fall onto the discharge rack for transportation; and the sleeve with the opening facing the same side of the turntable can be stuck in the through slot and then driven by the turntable to rotate out, and squeezed by the push plate to the discharge rack 2 for continuous output, so that the sleeves are screened in front and back through the mechanical structure, avoiding the situation where the imaging device is easily screened and transported incorrectly due to the different opening directions of the sleeves; By setting the spring 1 and the lower pressure shell, when the sleeve with the opening facing the rotating disk is pressed down, the spring 1 can be contracted in the lower pressure shell to reduce the pressure on the next sleeve and avoid damage to the sleeve; 3. The second rotary drive device drives a plurality of rollers to rotate, so that the sleeve squeezed by the lower pressure shell on the hinged plate can quickly slide out from the hinged plate, thereby improving the screening efficiency.

The first rotating drive device 409 can be a servo motor or a stepping motor. The turntable 41 is rotatably mounted on the frame 1. The turntable 401 is provided with a plurality of through slots 402 that are adapted to the diameter of the sleeve. The rotating block 403 is rotatably mounted in the through slot 402. The clamping block 404 that is adapted to the cross opening of the sleeve is installed on the rotating block 403. A gear 405 is installed, and a rack 406 is installed on the lower pressure shell 302. The gear 405 is meshed with the rack 406. A push plate 407 is slidably clamped in the through slot 402. A spring three 408 is installed on the rotating block 403. The output end of the spring three 408 is connected to the push plate 407. A first rotary drive device 409 is installed on the frame 1. The output end of the first rotary drive device 409 is transmission-connected to the turntable 401. An opening 410 is provided on the frame 1, and a discharging frame two 411 is installed on the frame 1. The first linear actuator 301 and the first rotary drive device 409 should be connected through a signal processing signal.

[0026] The sleeve is pushed down and laid flat by the loading machine 21 to be loaded onto the conveyor 22 for transportation. When the sleeve is transported to the turntable 401, it will abut against the turntable 401 and stop moving forward, while the conveyor 22 will not stop working. If the opening direction of the sleeve abutting against the turntable 401 is in the opposite direction of the turntable 401 at this time, the first linear actuator 301 can be driven to press down to generate pressure on the sleeve, thereby driving the hinge plate 304 under the sleeve to rotate, so that the hinge plate 304 rotates to abut against the receiving plate 309, so that the sleeve can slide downward along the receiving plate 309 under the push of the pushing mechanism 313, and when the hinge plate 304 rotates, the half gear 1 311 installed thereon can rotate with it, so that the meshing of the half gear 1 311 and the half gear 2 312 can make The rotating shaft 307 can drive the insertion rod 308 to rotate to the direction toward the receiving plate 309, and when the pushing mechanism 313 pushes the sleeve to slide down, the hollow sleeve can be directly inserted into the insertion rod 308, and then the first linear actuator 301 is slowly moved up and reset, and at the same time, under the support of the spring 2 306 in the telescopic support rod 305, the hinge plate 304 can be reset. At this time, through the meshing of the half gear 1 311 and the half gear 2 312, the sleeve on the insertion rod 308 can be driven by the rotating shaft 307 to turn to the side facing the discharge rack 310. At this time, due to the influence of the sleeve's own gravity, the sleeve can slide out along the discharge rack 310. Therefore, the first linear actuator 301 is continuously pressed down and reset, so that the sleeve with the opening in the opposite direction of the turntable 401 can be continuously output from the discharge rack 310.When the direction of the sleeve opening abutting against the turntable 401 is facing the turntable 401, the first linear actuator 301 continues to slowly descend a fixed length, and the lower pressure shell 302 at its output end will descend together, so that the lower pressure shell 302 can drive the rack 406 to descend together, and the rack 406 is meshed with the gear 406 on the rotating block 403, so that the rotating block 403 drives the clamping block 404 to rotate slowly, so that the sleeve opening can be stuck in the clamping block 404 and the entire sleeve can be stuck in the through groove 402. At this time, the lower pressure shell 302 at the output end of the first linear actuator 301 that continues to move downward will abut against the next sleeve, and the next sleeve will not be affected by the first linear actuator 301 because only a part of it is located on the articulated frame 304 and most of it is located on the frame 1. The linear actuator 301 pushes to deflect the hinge plate 304. The first linear actuator 301 that continues to press down will only squeeze the spring 303 in the lower pressure shell 302 to make it contract, but will not generate a large pressure on the next sleeve that is squeezed. After the first linear actuator 301 is pressed down and reset, the first rotary drive device 409 starts to drive the turntable 401 to rotate to a suitable angle. At this time, through the squeezing of the subsequent sleeve, the sleeve squeezed into the through groove 402 can be smoothly rotated out of the opening 410 on the frame 1. During the rotation process, the sleeve in the through groove 402 is first squeezed and limited by the subsequent sleeve and then limited by the frame 1 at the opening 410, so that the sleeve will be in a compressed state only after it is completely rotated out of the frame 1. The spring three 408 drives the push plate 407 to push the sleeve out. At this time, the sleeve can fall on the discharge rack two 411 and be continuously discharged. When the first linear actuator 301 is pressed down and reset, the sleeve opening may have been stuck in the block 404. At this time, the rotating rotating block 403 can drive the sleeve to rotate together. When the rotating block 403 rotates to make the sleeve opening stuck in the block 404, the push plate 407 is supported by the spring three 408 and is in the same plane as the outermost end of the block 404, thereby preventing the sleeve from bending the rotating block 404, and the push plate 407 is slidably connected to the rotating block 403, so that when it is pushed by the spring three 408, it can repair and correct the block 404. The clamped limiting column extends from the gear 405; the opening 410 is small, and only the sleeve clamped in the through slot 402 can be rotated and unscrewed; when the first linear actuator 301 is working downward, the lower pressure shell 302 will abut and limit the subsequent sleeve; the conveyor 22 is always running, and through friction, the sleeves on it all produce pressure on the sleeve abutting the turntable 401, so that the sleeve can smoothly compress the spring three 408 connected to the push plate 407; the spring 1 303 and the spring 2 306 can be special springs, such as high carbon steel springs, and the height position of the receiving plate 309 can be set so that the hinge plate 304 can be bent at a smaller angle to complete the work, thereby reducing the loss of the spring 1 303 and the spring 2 306. ;

[0027] In one embodiment, see Figure 6The pushing mechanism 313 includes a roller 3131, a second rotation driving device 3132 and a transmission assembly 3133. The second rotation driving device 3132 can be a micro motor, and the transmission assembly 3133 can be a belt transmission assembly. The rotating device on the upper surface of the hinged plate 304 has a plurality of rollers 3131. The second rotation driving device 3132 is connected to one of the rollers 3131 through a transmission assembly 3133. The rollers 3131 are connected to each other through a transmission assembly 3133. The second rotation driving device 3132 should also be connected through a signal processor signal so that it can rotate when the first linear actuator 301 is pressed down to the lowest end and stop rotating during its reset process.

[0028] By adopting the above technical solution, by setting a larger diameter of the roller 3131, it is made flush with the conveyor 22, which facilitates the installation of the second rotary drive device 3132, and the output end of the second rotary drive device 3132 can be connected to one of the rollers 3131 through a transmission assembly; the second rotary drive device 3132 drives all or several rollers 3131 to rotate through the transmission assembly 3133, thereby driving the sleeve squeezed by the lower pressure shell 302 and the hinged plate 304 to slide out.

[0029] In one embodiment, a connecting plate 51 is installed on the frame 1 . The connecting plate 51 is located on a side of the conveyor 22 away from the feeder 21 . The connecting plate 51 is chamfered.

[0030] By adopting the above technical solution, through the connection plate 51 and the chamfered corners thereon, the transport sleeve on the conveyor 22 can slide smoothly onto the connection plate 51 .

[0031] In one embodiment, an arc-shaped guide block 53 is installed at the bottom of the connecting plate 51 , and the arc-shaped guide block 53 is used to limit the position of the sleeve sleeved on the insertion rod 308 .

[0032] By adopting the above technical solution, when the sleeve slides out of the hinge plate 304, the hinge plate 304 will be driven by the compressed spring 2 306 to instantly rotate at a large angle. Even if the rotating shaft 307 rotates faster, at this time, only a part of the sleeve may be inserted into the insertion rod 308. Therefore, through the setting of the arc guide block 53, the sleeve that slides outward due to the centrifugal force on the insertion rod 308 can be limited by the arc guide block 53, and continues to stay on the insertion rod 308 and slides back to the insertion rod 308 by its own gravity. Afterwards, when the insertion rod 308 rotates to the discharge rack 310, the sleeve can also be limited so that it will not slide down prematurely.

[0033] In one embodiment, the hinge plate 304 is provided with rounded corners, and the receiving plate 309 and the arc-shaped guide block 53 are provided with rounded corners.

[0034] By adopting the above technical solution, the rotation of the hinge plate 304 and its abutment with the receiving plate 309 are facilitated, and the rounded corners on the arc-shaped guide block 53 can limit the sleeve and prevent it from sliding down prematurely.

[0035] In one embodiment, see Figure 5 A plurality of rollers 54 are rotatably mounted on the lower pressure shell 302 , and the rollers 54 are matched with the rollers 3131 .

[0036] By adopting the above technical solution, the roller 2 54 and the roller 3131 cooperate with each other to clamp the roller, so that when the pushing mechanism 309 pushes the sleeve to slide down, the friction between the sleeve and the lower pressure shell 302 can be reduced.

[0037] In one embodiment, see Figure 7 A card slot 55 is provided on the frame 1, and a connecting frame 56 is slidably connected in the card slot 55, and the rack 406 is installed on the lower pressure shell 302 through the connecting frame 56.

[0038] By adopting the above technical solution, when the lower pressure shell 302 moves downward, it can drive the rack 406 to move together through the connecting frame 56, and through the sliding engagement of the connecting frame 56 in the slot 55, when the lower pressure shell 302 is pressed downward, it can balance the thrust of the subsequent sleeve on it, so as to protect the first linear actuator 301.

[0039] In one embodiment, see Figure 7 Blocks 57 are installed on both sides of the connecting frame 56, and the block 57 abuts against the frame 1.

[0040] By adopting the above technical solution, the sliding engagement of the connecting frame 56 in the engagement groove 55 is achieved through the abutment between the engaging block 57 and the frame 1 .
