Description

Technical Field

[0001] This utility model relates to the field of high-speed wire rod production technology, specifically to an automated high-speed wire rod winding system. Background Technology

[0002] The coiling station is an online piece of equipment in the finishing area of ​​the high-speed wire rod production line, located between the air-cooled conveyor rollers and the PF line. The coiling station is responsible for collecting and transporting finished high-speed wire rods. It mainly consists of a coiling drum, a pallet lifting assembly, a double-arm mandrel, and a trolley. The high-speed wire rod is conveyed via rollers to the top of the coiling drum and falls onto the vertical mandrel in the double-arm mandrel. The pallet is used to hold the falling coil. The trolley is installed below the PF line, and the C-hooks on the cage move along the PF line. Normally, manual coiling requires turning 10 knobs and performing 15 actions within one minute or even less to complete one coiling, unwinding, and transporting process. Due to the fast production pace and complex operation, operators need highly skilled and focused personnel, and must be quick and agile in responding to unexpected malfunctions. It is one of the most challenging positions in the entire steel rolling process.

[0003] Currently, the positioning system of high-speed wire rod winding trolleys in China generally uses encoder positioning. Since the encoder is located on the drive motor side, mechanical transmission problems often cause inaccurate positioning of the winding trolley. This results in the winding trolley rolling out of the limit position track when reversing or rolling out of the limit position and hitting the wall when moving forward, frequently damaging the reducer. In the production of special products, the proximity switch of the lifting pallet is overheated during operation, causing equipment failure and affecting the normal production rhythm. Utility Model Content

[0004] The purpose of this invention is to provide an automated high-speed wire winding system to solve the problem of mechanical transmission failures causing inaccurate trolley positioning, resulting in the trolley running off the limit track or hitting the wall when entering or exiting the limit, which leads to equipment damage and affects the production rhythm.

[0005] To achieve the above objectives, the basic solution provided by this utility model is as follows: an automated high-speed wire winding system, including a trolley rangefinder, a double-arm mandrel, a winding drum, a roller conveyor, a cage, and a C-hook. The trolley rangefinder is located on the wall directly opposite the trolley. The trolley is equipped with an opening and closing assembly and a lifting assembly. The double-arm mandrel is located on the side of the trolley away from the trolley rangefinder. A pallet lifting assembly is located on the side of the double-arm mandrel away from the trolley. The winding drum is located above the pallet lifting assembly. The roller conveyor is located above the pallet lifting assembly and the double-arm mandrel. The winding drum is located at the end of the roller conveyor. A fork is movably inserted through the bottom of the winding drum. A cylinder is connected to the fork. A pallet rangefinder for detecting the height of the pallet lifting assembly is provided on the roller conveyor. An area switch is provided on the roller conveyor. The roller conveyor motor and the pallet rangefinder are both electrically connected to the area switch.

[0006] The working principle of this utility model is as follows: the steel material falls into the collecting drum through the roller conveyor, the pallet lifting assembly rises to the bottom of the collecting drum and closes on the mandrel, the steel material falling into the collecting drum falls onto the pallet, and after the pallet lifting assembly descends, it is stably fitted onto the mandrel. After the pallet lifting assembly leaves the mandrel, the vertical mandrel is driven by the motor to rotate to a horizontal state, and then the trolley is moved to the set receiving position by the trolley rangefinder, and then rises to the vertical mandrel by the lifting assembly, and then the steel material is fastened by the closing assembly. Finally, the trolley is moved backward to the set unloading position, so that the steel material is fitted onto the C-shaped hook.

[0007] The beneficial effects of this utility model are as follows: through the cooperation of the area switch, roller motor, pallet rangefinder, trolley rangefinder, and the lifting and closing components of the trolley, the situation of equipment accidents caused by the pallet losing signals or the trolley hitting the limit during operation is reduced, effectively preventing unsafe factors for workers caused by equipment accidents, and improving equipment utilization and production efficiency.

[0008] Option 2, a preferred option of the basic scheme, involves a support frame on the roller conveyor, with levers rotatably connected to both sides of the support frame. The levers are used to evenly move the various wires on the roller conveyor, preventing them from piling up.

[0009] Option 3, an optimal choice from the basic option, features a sliding track on the cage and pulleys on the C-hooks. The C-hooks and the sliding track are slidably connected via the pulleys. The sliding track prevents the open end of the C-hooks from hitting upwards when receiving wire, thus limiting the movement of the C-hooks.

[0010] Option 4, a preferred option of the basic scheme, includes an opening / closing proximity switch, a hydraulic pump mounted on the trolley, and a clamping arm rotatably connected to the trolley. The clamping arm is connected to the hydraulic pump, which is electrically connected to the opening / closing proximity switch. The opening / closing proximity switch senses the wires and transmits a pressurization or depressurization signal to the hydraulic pump, causing the trolley's stop arm to open and close.

[0011] Option 5, a preferred embodiment of Option 4, includes a lifting proximity switch, a second hydraulic pump mounted on the trolley, a support arm connected to the second hydraulic pump, and the second hydraulic pump electrically connected to the lifting proximity switch. The lifting proximity switch senses the mandrel, transmitting a pressurization or depressurization signal to the second hydraulic pump, causing the trolley's receiving end to rise or fall.

[0012] Option 6, a preferred option of Option 5, includes a fork opening / closing detection switch inside the winding drum, electrically connected to a cylinder. The fork opening / closing detection switch detects the wire position; when the wire reaches the designated position, the switch drives the cylinder to open and close the fork within the winding drum.

[0013] Option 7, a preferred embodiment of Option 6, includes an opening / closing proximity switch 2 on the pallet lifting assembly. This switch 2 is electrically connected to a pallet rangefinder. The pallet rangefinder detects the height of the lifting assembly, stops when a specified height is reached, and sends a signal to the opening / closing proximity switch 2, which then opens or closes the pallet.

[0014] Option 8, a preferred option of Option 7, connects the double-arm mandrel, opening / closing proximity switch 1, opening / closing proximity switch 2, fork opening / closing detection switch, lifting proximity switch, trolley rangefinder, pallet rangefinder, and area switch to the PLC control terminal. The PLC control terminal interlocks these components, enabling orderly cooperative production and collection between the devices. Attached Figure Description

The double-arm mandrel 5 is located on the side of the trolley 2 furthest from the trolley rangefinder 1. A pallet lifting assembly 6 is mounted on the side of the double-arm mandrel 5 furthest from the trolley 2. An opening / closing proximity switch 17 is mounted on the pallet lifting assembly 6 and electrically connected to the pallet rangefinder 9. Next, the collecting drum 7 is located above the pallet lifting assembly 6, and the roller conveyor 8 is located above the pallet lifting assembly 6 and the double-arm mandrel 5. A bracket 11 is provided on the roller conveyor 8, and levers 12 are rotatably connected to both sides of the bracket 11. A slide rail 14 is provided on the cage 13, and a pulley 16 is provided on the C-hook 15. The C-hook 15 and the slide rail 14 are slidably connected through the pulley 16.

A cylinder 19 is connected to the fork 18, and a fork opening / closing check is provided inside the collecting drum 7. The test switch 20 and the fork opening / closing detection switch 20 are electrically connected to the cylinder 19. The roller conveyor 8 is equipped with a pallet rangefinder 9 for detecting the height of the pallet lifting assembly 6. The roller conveyor 8 is equipped with an area switch 10. The motor of the roller conveyor 8 and the pallet rangefinder 9 are both electrically connected to the area switch 10. The double-arm mandrel 5, the opening / closing proximity switch 1 301, the opening / closing proximity switch 2 17, the fork opening / closing detection switch 20, the lifting proximity switch 401, the trolley rangefinder 1, the pallet rangefinder 9 and the area switch 10 are all electrically connected to the PLC control terminal.

[0023] The implementation method of this embodiment is as follows:

[0024] When the wire is transported on the roller conveyor 8, the lever 12 moves the wire to distribute it evenly. During the transport of the wire towards the winding drum 7, the area switch 10 detects the head and end of the wire. When the head of the wire enters the detection range of the area switch 10, the area switch 10 transmits a signal to the motor of the roller conveyor 8, automatically controlling the roller conveyor 8 to decelerate via the PLC control terminal. Then, the wire enters the winding drum 7 evenly. At this time, the shift fork 18 opens and is evenly distributed at the bottom of the winding drum 7. The coil entering the winding drum 7 falls onto the shift fork 18. Simultaneously, one arm of the double-arm mandrel 5 rotates to directly below the winding drum 7. Then, the pallet lifting assembly 6 slowly rises, and the pallet rangefinder 9 detects that the pallet lifting assembly 6 has risen to 1530. When the wire thickness reaches 0mm, a signal is transmitted to the second proximity switch 17, which in turn transmits a signal to the PLC control terminal. The PLC control terminal then controls the pallet lifting assembly 6 to close. When the coil accumulates to a certain height, the fork opening / closing detection switch 20 detects the coil signal and transmits it to the PLC control terminal. The PLC control terminal then controls the inner core of the double-arm mandrel 5 to rise, lifting the nose cone inside the winding drum 7. The rising of the nose cone in the winding drum 7 causes the fork 18 to retract, and then the wire inside the winding drum 7 falls onto the pallet lifting assembly 6. At this time, the tail end of the wire leaves the detection range of the area switch 10. The area switch 10 simultaneously transmits signals to the roller conveyor 8 motor and the pallet lifting assembly 6. After receiving the signal, the roller conveyor 8 motor accelerates, and the pallet lifting assembly 6 receives the signal. After receiving the signal, the pallet slowly descends. The height of the pallet lifting assembly 6 is then measured using the pallet rangefinder 9. When the height reaches 14500mm, the descent accelerates, and when it reaches 900mm, it decelerates, slowly falling to the bottom of the double-arm mandrel 5. A signal is then transmitted to the opening proximity switch 17 to open the pallet lifting assembly 6, allowing all the wire to be looped onto the mandrel. The double-arm mandrel 5 then begins to rotate, turning one arm with the wire from a vertical to a horizontal position. The other arm repeats the same process. The trolley 2 moves towards the double-arm mandrel 5, simultaneously transmitting a signal to the lifting proximity switch 401. The hydraulic pump 402 then controls the support arm 403 to rotate, lifting the receiving part of the trolley 2. At this time, the C-hook 15 moves on the cage 13 to face the trolley 2. The position is controlled by the trolley rangefinder 1 to control the movement distance of the trolley 2. When the distance of the trolley 2 reaches 18900mm, it stops. After the core rod with the wire is completely horizontal, it continues to move forward to 24300mm and stops. Then, it transmits a signal to the opening and closing proximity switch 301. The hydraulic pump 302 controls the clamping arm 303 to clamp the wire. Then the trolley 2 moves in the opposite direction to remove the wire from the core rod. When the trolley 2 reaches 14800mm, it slows down and moves slowly to put the wire on the C-hook 15. It stops at 14300mm. At this time, the wire is completely put on the C-hook 15. Then the trolley 2 continues to move towards the double-arm core rod 5. At the same time, it transmits a signal to the lifting component 4. The lifting component 4 descends and continues to repeat the above work.Finally, the C-hook 15, with the wire attached, continues to move on the cage 13 to the wire collection point.
