Description

Novel pickling shifts skip

Technical Field

The utility model relates to a pickling treatment facility is concentrated to wire rod specifically indicates that the novel pickling of material transfer usefulness in pickling production line is concentrated to wire rod shifts skip.

Background

The concentrated pickling line for wire rods (wires) generally adopts a transfer skip car to realize the transportation and transfer of workpieces among various devices such as a washing tank, a pickling tank, a phosphating tank, a drying box, a loading and unloading platform and the like. The transfer skip car all has fixed work position in every equipment, and the positioning mode of control transfer skip car is realized by installing travel switch near fixed work position more, and when the skip car will reach the work position, the block that bumps of dress on the skip car touch speed reduction travel switch, and skip car walking motor slows down, and when the block that bumps of dress on the skip car touch location travel switch, output signal control transfer skip car transmission motor stops to realize the skip car location. However, in the actual operation process, the operation speed of the skip car, the weight of the material and the like are influenced, and if the speed is not reduced in time, the skip car can not be stopped easily due to inertia overshoot. Meanwhile, due to the fact that the travel switch is low in precision, high in failure rate and lagging in reaction, the transfer skip car cannot be positioned accurately or cannot be positioned, the position needs to be calibrated manually, and the overall operation efficiency of the production line is affected.

Detailed Description

In order to better explain the technical scheme of the utility model, the scheme of the application is further introduced by combining the attached drawings of the specification.

See attached figure 1, the utility model discloses a this kind of novel pickling shifts skip, including skip 1, motor 2, rotary encoder 3, proximity switch 4, proximity switch tablet 5. The proximity switch is arranged on the outer side surface of the skip car, and the proximity switch sensing plate is arranged on a fixed working position of the skip car in each material receiving device. A proximity switch is respectively matched with a plurality of proximity switch induction plates which are arranged on a fixed working position in the equipment. The rotary encoder 3 is installed at the shaft end of the transmission shaft of the motor 2 and moves synchronously with the transmission shaft of the motor. The rotary encoder 3 is arranged coaxially and horizontally with the transmission shaft of the motor 2.

The rotary encoder is connected with the PLC and controlled, and a speed reduction point preset by the PLC is stored in the rotary encoder. The PLC controller is arranged on a transfer skip frame, before operation, parameter points, namely speed reduction points, of the rotary encoder are set through the PLC controller, half of the speed reduction points are arranged before the transfer skip is close to the proximity switch induction plate, and setting is carried out according to material weight and the load of the skip on the production line.

The rotary encoder and the proximity switch form double positioning locking of the transfer skip car, namely, the control of the rotary encoder on the motor is realized by setting a speed reduction point at the corresponding position of the rotary encoder, namely, the motor controls the speed of the transfer skip car to be reduced, and whether the transfer skip car reaches a fixed working position of the receiving equipment is judged by the counting function of the rotary encoder, so that the first repositioning locking is realized, the speed reduction control is implemented in advance, and the skip car overshoot condition caused by various factors is avoided. When the skip arrives at the appointed fixed working position, whether the skip is in place is judged through the proximity switch, and the positioning accuracy of the skip is ensured, so that the skip is locked in a second repositioning mode. The running condition and the in-place condition of the skip car are subjected to secondary position correction by the rotary encoder and the proximity switch respectively to form mutual locking double positioning.
