Description

Technical Field

[0001] The present invention relates to the technical field of coiling and hanging equipment, and particularly to a coiling trolley and C-hook hanging system and a control method thereof. Background Art

[0002] In the production process of wire rods, the coiling trolley is often used to transport the coiled materials to the C-hook. The hanging position is calculated by the encoder value, the gearbox speed ratio, and the roller diameter to calculate the trolley position, so as to transport the coiled materials to the C-hook and transfer them to the next packing process. If the roller slips and idles or is blocked and idles during the trolley running, it will cause the abnormal calculation value of the trolley hanging position, making the coiled materials not centered on the central part of the C-hook, resulting in the following consequences:

[0003] The discharging position is inaccurate, which may cause the instability of the coiled material and easy to fall, resulting in the occurrence of wire hanging;

[0004] It is easy to cause uneven force on the C-hook. Long-term eccentric loading may cause local stress concentration, resulting in hook body deformation, weld cracking or fatigue damage of the support structure;

[0005] The inclination and offset of the C-hook cause the subsequent process packing to be unable to be normally connected, prolonging the production cycle and affecting the bundling cycle to be lengthened;

[0006] The above problems increase the maintenance cost and production cost, resulting in low production efficiency.

[0007] Therefore, a coiling trolley and C-hook hanging system and a control method are provided to solve the above problems. Summary of the Invention

[0008] The main purpose of the present invention is to solve the problems in the prior art that the coiled materials are not centered on the central part of the C-hook, resulting in inaccurate discharging position, which may cause the instability of the coiled material and easy to fall, resulting in the occurrence of wire hanging; it is easy to cause uneven force on the C-hook. Long-term eccentric loading may cause local stress concentration, resulting in hook body deformation, weld cracking or fatigue damage of the support structure; the inclination and offset of the C-hook cause the subsequent process packing to be unable to be normally connected, prolonging the production cycle and affecting the bundling cycle to be lengthened, etc.

[0009] The first aspect of the present invention provides a coiling trolley and C-hook hanging system, and the coiling trolley and C-hook hanging system includes:

[0010] A turning table, a coiling and hanging trolley, and a C-hook. The coiling and hanging trolley is arranged between the turning table and the C-hook. A trolley position laser rangefinder is fixedly installed at the end of the support leg of the turning table close to the coiling and hanging trolley. The coiling and hanging trolley includes a trolley moving seat, a trolley lifting mechanism, and a coiling clamping platform. The trolley lifting mechanism is fixedly installed on the trolley moving base, and the coiling clamping platform is fixedly installed at the upper end of the trolley moving base.

[0011] Further, a ranging target is arranged on the trolley moving base in cooperation with the trolley position laser rangefinder, and the target and the trolley position laser rangefinder are on the same horizontal plane.

[0012] Further, the coiling clamping platform includes a clamping platform, a sliding track is arranged on the clamping platform, a clamping arm is arranged at one end of the sliding track, a moving arm is arranged on the sliding track, and a moving arm laser rangefinder is arranged at the end of the sliding track away from the clamping arm.

[0013] Further, the sliding tracks are arranged in pairs, the opposite surfaces of the two sliding tracks are inclined planes, the moving arm includes a moving driving mechanism and a moving clamping mechanism, the moving driving mechanism is sleeved on the sliding track, and the moving clamping mechanism is fixedly installed on the moving driving mechanism.

[0014] Further, the trolley lifting mechanism includes a lifting driving cylinder and an X-shaped lifting frame, the lifting driving cylinder is used to drive the X-shaped lifting frame to lift, and the lifting driving cylinder is fixedly installed on the side away from the clamping arm.

[0015] Further, the C-shaped hook is fixedly arranged on the hoisting mechanism.

[0016] Further, a ground track is also included, the ground track is used to cooperate with the trolley moving base, and the ground track is fixedly installed on the ground.

[0017] The second aspect of the present invention provides a coiling trolley and C-shaped hook loading control method, including:

[0018] Step 1. Obtain the distance from the inner wall plane of the clamping arm after closing at the material receiving position of the trolley to the center position of the C-shaped hook, denoted as L; obtain the distance from the moving arm of the trolley to the inner wall plane position after the clamping arm is closed, denoted as L1;

[0019] Step 2. When the trolley receives the material, the clamping arm fixes the coil material, and the advancing distance of the moving arm is obtained through the moving arm laser rangefinder, denoted as S, and it can be calculated that: the coil length S1 = L1 - S;

[0020] Step 3. Calculate the length from the center position of the coil material to the center position of the C-shaped hook, denoted as S2, S2 = L1 - ((L1 - S) / 2);

[0021] Step 4. Obtain the advancing distance of the coiling and loading trolley through the trolley position laser rangefinder. When the length detected by the trolley position laser rangefinder = S2; it is determined that the center position of the coil material is aligned with the center position of the C-shaped hook, and a discharging command for the transporting trolley can be given.

[0022] The present invention provides a coiling trolley and C-hook loading system. The traveling position of the trolley is detected by an encoder. If the rollers of the trolley slip or idle during travel or are blocked and idling, it will cause the calculated value of the trolley's loading position to be abnormal. In the present invention, it is detected by a laser rangefinder, and the calculation of the hook position value is not affected by slipping, jamming and other conditions. The detection of the forward position of the moving arm will not cause inaccurate detection of the forward distance value due to reasons such as the idling or tooth skipping of the moving arm chain, improving the accuracy. It can be further adjusted according to the length of the coil material to adjust the loading position to the C-hook, improving the accuracy of the hook position. It effectively avoids abnormal situations caused by poor hook positions of the coil materials. BRIEF DESCRIPTION OF THE DRAWINGS
