Description

Technical Field

[0001] This utility model relates to the field of metallurgical conveying equipment, and in particular to a PF line stopper. Background Technology

[0002] PF lines are used to transport integrated wire coils to the unloading station, while the stopper is a key device for controlling the rhythm of coil conveying. It is mainly used to temporarily block the coils to achieve positioning, grouping or buffering of the coils, so as to ensure the smooth progress of subsequent processes (such as bundling and tagging).

[0003] Utility model patent CN218878507U discloses a stopping device for a PF conveyor line. When the trolley passes through the conveyor track, the telescopic rod on the telescopic cylinder retracts, and the stop plate rotates to its highest position under the drive of the telescopic cylinder. At this time, the chain hook on the conveyor track is lifted by the stop plate, causing the trolley to disengage from the hook and stop moving. When the trolley needs to move, the telescopic rod on the telescopic cylinder extends, and the stop plate rotates downward under the drive of the telescopic cylinder, causing the chain hook to descend and hook the trolley, thus driving the trolley to move. Since the chain is always moving, in order to ensure that the trolley does not move during the stop period, the stop plate needs to be maintained at the highest position, which causes the stop plate to be hooked or rubbed by subsequent chain hooks, increasing the failure rate of the stop plate. Furthermore, the above-mentioned stopping device does not include a signal component for controlling the start and stop of the trolley. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a PF line stopper with signal components and braking components that can be used in conjunction with existing coil transport lines.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A PF line stopper includes a signal component and a braking component located on one side of the conveying track. The signal component provides a stop signal, and then the controller activates the braking component to stop the C-hook trolley from moving. The signal component includes a fixed plate, fixed lugs, a rotating roller, a connecting plate, a rotating plate, a signal plate, and a detector. The fixed plate is fixedly connected to the conveying track and has fixed lugs symmetrically arranged on it. The rotating roller is axially connected to the fixed lugs. A connecting plate is fixedly arranged on one side of the rotating roller. A rotating plate is fixedly connected below the connecting plate. The signal plate is also arranged on the rotating roller. A trigger rod is provided on the suspension arm of the C-hook trolley. The installation height of the trigger rod is higher than the lowest point of the rotating plate.

[0007] In the aforementioned PF line stopper, both the front and rear ends of the rotating plate are inclined.

[0008] The detector in the aforementioned PF line stopper is a proximity switch, which is mounted on a fixed lug.

[0009] The aforementioned PF line stopper has a clearance groove on its fixed ear seat.

[0010] The aforementioned PF line stopper includes a braking assembly located in front of the signal assembly, comprising a support base plate, a braking cylinder, an adapter plate, and a blocking plate. One end of the support base plate is fixed to the conveying track, and a braking cylinder is mounted on its upper surface. The output end of the braking cylinder is connected to the adapter plate, which is L-shaped, and its other end is connected to the blocking plate.

[0011] The aforementioned PF line stopper, the braking assembly further includes guide blocks and rotating rollers. Guide blocks are symmetrically arranged on the support base plate. A blocking plate and a transition plate are located between the two guide blocks. Each guide block has a rotating shaft seat at its upper end. The two rotating shaft seats are axially connected to the rotating roller. The rotating roller is in contact with the upper end surface of the blocking plate.

[0012] The aforementioned PF line stopper has a partition on the suspension arm of the C-type hook trolley. The longitudinal section of the partition is triangular and it is fixedly connected to the suspension arm behind the vehicle frame in the direction of travel.

[0013] The beneficial effects of adopting the above technical solution are as follows:

[0014] This invention features a trigger rod on the suspension arm of the C-hook trolley. When the C-hook trolley moves downwards towards the signal assembly, the trigger rod lifts the rotating plate of the signal assembly, causing the plate to rotate around the rotating roller at a certain angle. This, in turn, drives the signal plate to rotate. The detector transmits the rotation signal of the signal plate to the controller, which promptly activates the braking assembly to stop the C-hook trolley, thus fulfilling the various process actions of the coil transport line. Furthermore, the braking assembly of this invention utilizes a brake cylinder to move a blocking plate and a transition plate along a guide block. The blocking plate separates the connection between the push block and the driving claw, thereby causing the C-hook trolley to lose driving force and stop moving. A rotating shaft is also provided above the guide block, with a rotating roller pressing against the blocking plate. As the rollers rotate with the movement of the baffle plate, they can press the baffle plate firmly while reducing the resistance and friction between the baffle plate and the rotating rollers. In order to prevent the running C-hook trolley from colliding with the stopped trolley in front, this utility model also includes a partition set behind the suspension arm of the C-hook trolley. The tip of the partition located on the front C-hook trolley will enter between the control lever and the support plate of the rear C-hook trolley. As the rear C-hook trolley moves, the counterweight on the control lever gradually rises. The rise of the counterweight eventually drives the claw to fall, and the push block of the drive chain separates from the connecting groove of the rear C-hook trolley. The rear C-hook trolley stops moving, thereby avoiding collision between the front and rear trolleys in operation and reducing the failure rate of the coil transport line.

[0022] like Figure 1 , 3As shown, in one embodiment of this utility model, a PF line stopper is mounted on one side of the conveyor rail 1 of the coil transport line. A drive chain 2 is provided on the upper part of the conveyor rail 1, and a pusher block 21 is arranged at regular intervals below the drive chain 2 to drive the C-hook trolley 3. The C-hook trolley 3 includes a C-hook 31, a suspension arm 32, a suspension support arm 33, a frame 34, and wheels 35. The suspension arm 32 is fixedly connected above the C-hook 31, and multiple suspension supports 33 are evenly spaced above the suspension arm 32. A frame 34 is fixedly connected above each suspension support arm 33, and wheels 35 are mounted inside the frame 34. The wheels 35 are located within the conveyor rail 1. The C-hook trolley 3 moves along the conveyor track 1. A switch assembly is located inside the suspension arm 33, which is positioned in front of the trolley in the direction of travel. The switch assembly includes a drive claw 36, a control lever 37, and a support plate 38. The support plate 38 is fixedly connected to the suspension arm 33. One end of the control lever 37 is a counterweight 371, with its middle section hinged to the side wall of the suspension arm 33. The other end is hinged to the bottom of the drive claw 36. The top two sides of the drive claw 36 are inclined, and a connecting groove 361 is provided in the center. The connecting groove 361 cooperates with the push block 21, causing the push block 21 below the drive chain 2 to enter the connecting groove 361 at the top of the drive claw 36. As the drive chain 2 moves, the C-hook trolley 3 is propelled to move.

[0023] like Figure 1-5 As shown, in one embodiment of this utility model, a PF line stopper includes a signal component 4 and a braking component 5 located on one side of the conveying track. The signal component 4 provides a stop signal, and then the controller activates the braking component 5 to stop the C-hook trolley 3. The signal component 4 includes a fixed plate 41, fixed lugs 42, a rotating roller 43, a connecting plate 44, a rotating plate 45, a signal plate 46, and a detector 47. The fixed plate 41 is fixedly connected to the conveying track 1, and fixed lugs 42 are symmetrically arranged on it. A rotating roller 43 is axially connected to the fixed lugs 42, and a connecting plate 44 is fixedly arranged on one side of the rotating roller 43. A rotating plate 45 is fixedly connected below the connecting plate 44. A signal plate 46 is also provided on the rotating roller 43. A trigger rod 331 is provided on the suspension arm 33 of the C-type hook trolley 3. The installation height of the trigger rod 331 is higher than the lowest point of the rotating plate 45. When the trigger rod 331 of the C-type hook trolley 3 moves downward to the signal assembly, the trigger rod 331 will contact and lift the rotating plate 45, causing the rotating plate 45 to rotate at a certain angle around the rotating roller 43, thereby driving the signal plate 46 to rotate. The detector 47 transmits the rotation signal of the signal plate 46 to the controller, and the controller controls the braking assembly 5 to start, so that the C-type hook trolley 3 stops moving.

[0024] To prevent the rotating plate 45 from jamming the trigger rod 331, both the front and rear ends of the rotating plate 45 are inclined. The trigger rod first contacts the inclined surface of the rotating plate 45, then moves forward along the inclined surface and lifts the rotating plate 45.

[0025] The detector 47 described in this utility model is a proximity switch, which is mounted on the fixed ear base 42.

[0026] like Figure 4 As shown, each of the fixed ear seats 42 is provided with a relief groove 421. When the rotating plate 45 is lifted, the upper end of the rotating plate 45 is located in the relief groove 421.

[0027] like Figure 1 , 2 As shown in Figure 5, the braking assembly 5 is located in front of the signal assembly 4 and includes a support base plate 51, a brake cylinder 52, an adapter plate 53, and a blocking plate 54. One end of the support base plate 51 is fixed to the conveying track 1, and the brake cylinder 52 is mounted on its upper end. The output end of the brake cylinder 52 is connected to the adapter plate 53, which is L-shaped. The other end of the adapter plate 53 is connected to the blocking plate 54. When the controller sends a stop signal, the output end of the brake cylinder 52 drives the blocking plate 54 to move towards the middle of the conveying track 1. The side wall of the blocking plate 54 first contacts the inclined end of the driving claw 36, and as the C-type hook trolley 3 moves, the driving claw 36 gradually moves downward until it separates from the push block 21 of the drive chain 2. The C-type hook trolley 3 loses driving force and stops moving.

[0028] like Figure 2 , 5 As shown, the braking assembly 5 also includes guide blocks 55 and rotating rollers 56. Guide blocks 55 are symmetrically arranged on the support base plate 51. A blocking plate 54 and a connecting plate 53 are located between the two guide blocks 55. Each guide block 55 has a rotating shaft seat 551 at its upper end. The two rotating shaft seats 551 are axially connected to the rotating rollers 56. The rotating rollers 56 are in contact with the upper end face of the blocking plate 54. The rotating rollers 56 press against the blocking plate 54. The rollers rotate when the blocking plate 54 moves, which can press the blocking plate 54 tightly while reducing the resistance and friction between the blocking plate 54 and the rotating rollers 56.

[0029] like Figure 3As shown, the C-type hook trolley 3 has a partition 332 on its suspension arm 33. The partition 332 has a triangular longitudinal section and is fixedly connected to the suspension arm 33 at the rear of the trolley in the direction of travel. When one C-type hook trolley 3 stops moving, another C-type hook trolley 3 moves forward. When the two approach each other, the tip of the partition 332 of the front C-type hook trolley 3 enters between the control lever 37 and the support plate 38 of the rear C-type hook trolley 3. As the rear C-type hook trolley 3 moves, the counterweight 371 on the control lever 37 of the rear C-type hook trolley 3 gradually rises. The rise of the counterweight 371 causes the connection end between the control lever 37 and the driving claw 36 to fall. Finally, the driving claw 36 falls, and the push block 21 of the drive chain 2 separates from the connecting groove 361 of the rear C-type hook trolley 3. The rear C-type hook trolley 3 stops moving, preventing the rear C-type hook trolley 3 from pushing the front trolley to move.

[0030] Work process:

[0031] 1. When the C-type hook trolley 3 moves to below the signal assembly 4, the trigger rod 331 on the suspension arm 33 contacts and lifts the rotating plate 45. The rotating plate 45 rotates at a certain angle around the rotating roller 43, thereby driving the signal plate 46 to rotate. The detector 47 detects the rotation of the signal plate 46, and the controller controls the braking assembly 5 to start.

[0032] 2. The output end of the brake cylinder 52 drives the adapter plate 53 and the blocking plate 54 to move towards the middle of the conveying track 1. The height of the blocking plate is below the push block. When the switching assembly of the C-type hook trolley 3 moves to the blocking plate, it drives the claw to descend below the blocking plate under the action of the blocking plate and disengage from the push block. The C-type hook trolley 3 loses driving force and stops moving.

[0033] 3. The output end of the brake cylinder 52 drives the adapter plate 53 and the blocking plate 54 to return to their original positions. The counterweight block descends due to gravity and drives the connection end of the control lever 37 and the driving claw 36 to rise, so that the push block 21 below the drive chain 2 enters the connection groove 361 at the top of the driving claw 36. As the drive chain 2 moves, it pushes the C-shaped hook trolley 3 to move. After losing the support of the trigger lever 331, the turn plate 45 descends due to gravity and drives the signal plate 46 away from the detector 47.
