Description

Technical Field

[0001] This invention relates to the field of PF wire production and conveying technology, specifically a PF wire limit and stop device. Background Technology

[0002] During the production and processing of PF wire, the PF wire coils are auxiliaryly transported by a suspended chain conveyor. During this transport, the PF wire coils are placed on the U-shaped hooks of the vehicle assembly. The chain on the suspended chain conveyor drives the vehicle assembly and the PF wire on it, moving the PF wire to different workstations for processing. After the PF wire is moved to the designated position, a stopping device is needed to drive the stop plate to extend outward and press down the lifting claw of the vehicle group, so that the chain can no longer carry the vehicle group to stop. In order to reduce the resistance in the transmission process, a flexible drive is adopted during the process of the stopping device driving the stop plate to extend. However, during the operation of the stopping device using flexible drive, the stop plate is prone to swinging during the movement, which affects the accuracy of the stop plate pressing down on the lifting claw and may even cause the stopping to fail. Therefore, we propose a PF wire limit stopping device. Summary of the Invention

Detailed Implementation

[0016] 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.

[0017] Please see Figures 1-9 The diagram shows a PF wire limit stop device, which includes a mounting frame 101. The mounting frame 101 is detachably mounted on a suspended chain conveyor line by bolts. Multiple sets of vehicles are conveyed and connected on the suspended chain conveyor line. Each vehicle set is equipped with a lifting claw for driving against the chain on the suspended chain conveyor line. The mounting frame 101 is equipped with a stop plate 102 for driving and controlling the lifting claw to stop the vehicle set. It should be noted here that: on the suspended chain conveyor line, after the PF wire is moved to the designated position, the stop device is used to drive the stop plate 102 to extend outward, press down the lifting claw of the vehicle group, so that the chain can no longer carry the vehicle group to continue moving, thus achieving the purpose of stopping; In addition, the extension of the stop plate 102 to press down on the lifting claw is a conventional technical means in this application, and its working principle and operation method will not be described in detail here. Also includes: A pushing component is provided on the mounting frame 101 for pushing the stop plate 102. The mounting frame 101 is provided with a first guiding component for guiding the stop plate 102 during the pushing process, and a recognition component for recognizing the pushing state is provided on the mounting frame 101. Anti-sway wheel 5 is set on stop plate 102 to prevent swaying during the pushing of stop plate 102. Multiple sets of anti-sway wheel 5 are provided. An installation component for auxiliary installation is provided between stop plate 102 and anti-sway wheel 5. In addition, a support assembly for supporting the anti-sway wheel 5 is provided on the mounting frame 101, and an adjustment assembly for adjusting the support state of the support assembly is provided on the mounting frame 101. It should be noted that: on the suspended chain conveyor line, after the PF wire is moved to the designated position, the stop device is used to drive the stop plate 102 to extend outward, press down the lifting claw of the vehicle group, so that the chain can no longer carry the vehicle group to stop. During the extension of the stop plate 102, the support component and the adjustment component reduce the probability of the stop plate 102 swaying during the extension and reset movement, ensure the accuracy of the stop plate 102 pressing down on the lifting claw, and avoid stopping failure.

[0018] Preferably, the pushing component includes a fixed frame 201 fixed to one side of the mounting frame 101, a cylinder 202 is provided on one side of the mounting frame 101, one end of the cylinder 202 is rotatably connected to the fixed frame 201 by a pin, and a U-shaped frame 203 is installed at the output end of the cylinder 202, and the U-shaped frame 203 is rotatably connected to one side of the stop plate 102 by a pin. It should be noted that during the process of extending the stop plate 102, the stop device causes the stop plate 102 to move under force through the driving action of the cylinder 202 and the connecting action of the U-shaped frame 203.

[0019] Preferably, two sets of first guide components are symmetrically arranged on the mounting frame 101. The guide components include a first guide plate 401 and a second guide plate 402 fixed to one side of the mounting frame 101, and a stop plate 102 is slidably connected between the first guide plate 401 and the second guide plate 402. It should be noted that during the movement of the stop plate 102, the two sets of first guide plates 401 and second guide plates 402 slide and guide the stop plate 102, causing the stop plate 102 to be forced to extend outward of the mounting bracket 101. The purpose of stopping is achieved through the transmission between the extended stop plate 102 and the lifting claw.

[0020] Preferably, the mounting assembly includes a through hole 601 formed on the anti-sway wheel 5 and the stop plate 102, a T-bolt 602 is connected to the anti-sway wheel 5 through the through hole 601, and a nut 603 is connected to the T-bolt 602. It should be noted here that: the T-bolt 602 is passed through the through hole 601 on the anti-sway wheel 5 and the stop plate 102. After passing through, the nut 603 is connected to the T-bolt 602 and abuts against the upper end of the stop plate 102 to complete the installation of the anti-sway wheel 5.

[0021] Preferably, the support assembly includes two sets of side plates 701 symmetrically arranged on the mounting frame 101, two sets of support plates 702 are arranged between the two sets of side plates 701, and an elastic component for auxiliary elastic support is arranged between the side plates 701 and the support plates 702. The anti-sway wheel 5 is located between the two sets of support plates 702 and is abutted against each other. It should be noted that during the driving of the stop plate 102, the installation and connection of the mounting components drive the anti-sway wheels 5 on the stop plate 102 to move synchronously. During the movement of the anti-sway wheels 5, the elastic compression of the elastic components on the side plate 701 causes the two sets of support plates 702 to abut against the two sides of the anti-sway wheels 5 respectively. Through the abutment and compression, the anti-sway wheels 5 and the stop plate 102 are supported during the movement, reducing the probability of the stop plate 102 swaying during the extension and reset movement.

[0022] Preferably, the elastic component includes multiple sets of sleeves 801 fixed on the side plate 701, a slide rod 802 slidably connected on the sleeve 801, one end of the slide rod 802 being fixed to the support plate 702, and a spring 803 being sleeved on the outside of the sleeve 801, with both ends of the spring 803 abutting against the side plate 701 and the support plate 702 respectively. It should be noted that: the multiple sets of sleeves 801 and slide rods 802 facilitate the telescopic connection between the auxiliary side plate 701 and the support plate 702, and the spring 803 facilitates the elastic pushing of the support plate 702.

[0023] Preferably, the adjustment assembly includes a threaded sleeve 901 fixed on the side plate 701, a double-ended lead screw 902 rotatably connected to the mounting bracket 101, and the threads at both ends of the double-ended lead screw 902 are arranged in opposite directions. The two sets of threaded sleeves 901 are respectively engaged with the two ends of the double-ended lead screw 902. One end of the double-ended lead screw 902 is located outside the mounting bracket 101 and is fixed with a drive pin 903. A second guide assembly for guiding during the adjustment process is provided between the mounting bracket 101 and the two sets of side plates 701. The second guide assembly includes two sets of guide holes 1001 opened on the side plate 701. The two sets of guide holes 1001 are symmetrically arranged on both sides of the threaded sleeve 901. A guide rod 1002 is slidably connected to the guide hole 1001 and the guide rod 1002 is fixed on the mounting bracket 101. It should be noted here that: to avoid excessive support force causing resistance to the movement of the anti-sway wheel 5, and to avoid insufficient support force affecting the support effect of the anti-sway wheel 5, the elasticity of the elastic component is adjusted. During the adjustment process, the double-ended lead screw 902 is driven to rotate by the drive pin 903. Because the threads at both ends of the double-ended lead screw 902 are set in opposite directions, during the rotation of the double-ended lead screw 902, the two sets of threaded sleeves 901 respectively mesh with the two ends of the double-ended lead screw 902, causing the two sets of side plates 701 to move under force. During the movement of the two sets of side plates 701, the guide hole 1001 and the guide rod... The sliding guide function of 1002 causes the two sets of side plates 701 to move closer or further apart after being subjected to force. Because the support plate 702 abuts against the outer side of the anti-sway wheel 5, the movement of the side plates 701 causes relative movement between the side plates 701 and the support plate 702. During the relative movement, each set of sliding rods 802 is subjected to force and slides on each set of sleeves 801, causing the spring 803 to deform. Through the deformation of the spring 803, the elastic force generated by the spring 803 on the support plate 702 is changed, which further facilitates the support plate 702 to abut against the anti-sway wheel 5 with different elastic forces, making the support assembly more flexible to operate and use.

[0024] Preferably, the identification component includes a mounting plate 301 fixed on the mounting bracket 101, an identification block mounted on the stop plate 102, and a first proximity sensor 302 for identification when the stop plate 102 is reset and a second proximity sensor 303 for identification after the stop plate 102 is pushed out. It should be noted here that during the process of pushing out and resetting the stop plate 102, the movement of the stop plate 102 drives the identification block to move synchronously. During the movement of the identification block, the first proximity sensor 302 and the second proximity sensor 303 respectively identify and judge the reset position and the push-out position of the stop plate 102, so as to facilitate the more accurate reset and push-out of the stop plate 102. It is worth noting here that the identification block, the first proximity sensor 302 and the second proximity sensor 303 are conventional distance identification components, and their working principles and operation methods are known technologies in this application, so they will not be described in detail here.

[0025] In this solution: a PF wire limit stop device includes the following steps: After the PF wire on the suspended chain conveyor is moved to the designated position, a stopping device is needed to drive the stop plate 102 to extend outward, press down the lifting claw of the vehicle group, and prevent the chain from carrying the vehicle group to continue moving, thus achieving the purpose of stopping. During the process of driving the stop plate 102 to extend, the stopping device uses the driving action of the cylinder 202 and the connecting action of the U-shaped frame 203 to make the stop plate 102 move under force. During the movement of the stop plate 102, the sliding guiding action of the two sets of first guide plates 401 and second guide plates 402 makes the stop plate 102 extend outward from the mounting frame 101 under force. The purpose of stopping is achieved through the transmission between the extended stop plate 102 and the lifting claw. During the driving process of the stop plate 102, the installation and connection of the mounting components drive the anti-sway wheels 5 on the stop plate 102 to move synchronously. During the movement of the anti-sway wheels 5, the elastic compression of the elastic components on the side plate 701 causes the two sets of support plates 702 to abut against the two sides of the anti-sway wheels 5 respectively. Through the abutment and compression, the anti-sway wheels 5 and the stop plate 102 are supported during the movement, reducing the probability of the stop plate 102 swaying during the extension and reset movement, ensuring the accuracy of the stop plate 102 pressing down on the lifting claw, and avoiding stopping failure. During the push-out and reset driving process of the stop plate 102, the movement of the stop plate 102 drives the identification block to move synchronously. During the movement of the identification block, the first proximity sensor 302 and the second proximity sensor 303 respectively identify and judge the reset position and push-out position of the stop plate 102, which facilitates more accurate reset and push-out of the stop plate 102. During the process of using the support assembly to provide auxiliary support for the anti-sway wheel 5, in order to avoid excessive support force causing resistance to the movement of the anti-sway wheel 5 and to avoid insufficient support force affecting the support effect of the anti-sway wheel 5, the elasticity state of the elastic assembly is adjusted. During the adjustment process, the double-ended lead screw 902 is driven to rotate by the drive pin 903. Because the threads at both ends of the double-ended lead screw 902 are set in opposite directions, during the rotation of the double-ended lead screw 902, the two sets of threaded sleeves 901 respectively mesh with the two ends of the double-ended lead screw 902, causing the two sets of side plates 701 to move under force. During the movement of the two sets of side plates 701, the guide hole 1 is used to guide the movement. The sliding guide effect of 001 and guide rod 1002 causes the two sets of side plates 701 to move closer or further apart after being subjected to force. Because the support plate 702 abuts against the outer side of the anti-sway wheel 5, the movement of the side plate 701 causes relative movement between the side plate 701 and the support plate 702. During the relative movement, each set of sliding rods 802 is subjected to force and slides on each set of sleeves 801, causing the spring 803 to deform. Through the deformation of the spring 803, the elastic force generated by the spring 803 on the support plate 702 is changed, which further facilitates the support plate 702 to abut against the anti-sway wheel 5 with different elastic forces, making the support assembly more flexible to operate and use.
