Description

Technical Field

[0001] The utility model belongs to the technical field of steel coil production devices, and in particular relates to a circumferential positioning and fixing device for a hanging head of an uncoiler. Background Art

[0002] Silicon steel coils are the raw materials for producing transformer cores. In the process of processing silicon steel coils into transformer cores, the silicon steel coils need to be transported to the uncoiler for striping and slicing. After production is completed, the remaining coils need to be unloaded from the uncoiler and put into storage. With the development of automation and intelligence in transformer core processing, the entire process requires automatic operation, and the coil transportation equipment needs to be automatically docked with the uncoiler. A docking port is set at a specific position of the hanging head on the uncoiler. When the two are transporting and handing over the coils, the docking port of the uncoiler needs to be rotated to the target position and the docking port needs to be accurately positioned and fixed reliably to prevent the smooth progress of the docking process due to misalignment or movement during the docking process, or even collision, which will damage the coil and equipment. Therefore, the uncoiler hanging head must have a circumferential positioning and fixing device.

[0003] In order to make the structure compact and reduce costs, a multi-head uncoiler usually uses a set of rotary drive units to drive multiple uncoiler heads to rotate. A driving pinion is provided on the rotary drive unit, and a large gear is provided on each uncoiler head. When you want to drive a specific uncoiler head to rotate and unload, you need to insert the small gear on the rotary drive unit into the large gear on the head at the beginning for meshing transmission. At this time, the other uncoiler heads are not meshed with the small gears and are in a free state in the circumferential direction. When switching the uncoiler head to the driving position (unwinding working position), the teeth of the large gear on the uncoiler head that is about to mesh with the rotary drive pinion are likely to be misaligned with the teeth of the rotary drive pinion, and a collision will occur during insertion, making insertion difficult.

The document does not solve the problem that the teeth of the large gear on the unwinding hanging head of the rotating drive pinion meshing transmission are not easy to align with the teeth of the rotating drive pinion, and collision occurs during insertion, causing insertion difficulties.

When it is necessary to position the docking interface of the hanging head to the vertical position directly above from any angle, first make the rotary drive pinion 2.1 mesh with the hanging head large gear 1.1, and then the rotary drive mechanism 2 rotates at a low speed. At this time, the signal block 3 and the positioning block rotate at a low speed with the hanging head large gear 1.1 until the signal block 3 rotates to the signal sensor 4, and the signal sensor 4 sends a signal. After receiving the signal, the PLC immediately orders the rotary drive mechanism 2 to stop, and the rotary drive mechanism 2 brakes are tightened. Next, the PLC orders the linear drive mechanism 7 to control the valve to move, so that the linear drive mechanism 7 pushes out the positioning pin 6, and the positioning pin 6 is pressed into the V-groove on the positioning block 5; then, the PLC orders the rotary drive mechanism 2 motor brake to release, and the positioning pin 6 is accurately inserted into the V-groove; at this time, the unwinding and hanging head 1 accurately positions the docking port in the vertical direction directly above the position, and is reliably fixed.

[0059] The utility model can stop the uncoiler hanging head at a set circumferential position, and accurately position and fix it. It ensures that the docking port on the uncoiler hanging head can be accurately positioned and fixed, so as to ensure that the uncoiler and the coil conveying equipment are docked for coil conveying, and the docking process is accurate and reliable. It ensures that a set of driving units drives the uncoilers with multiple hanging heads, and the small gear of the driving unit and the large gear on the hanging head can be smoothly inserted and meshed, reducing the number of insertion failures.
