Abstract

The utility model provides a hot rolling shunt winding wire automatic centering and upwards winding device. An encoder is installed in the operating direction of an upwards winding machine, and an inlet step beam and the center line of a preparation station are respectively provided with a limiting switch. A functional controlling block is additionally arranged in a CPU. The encoder and the limiting switches are respectively connected with the FC. When stop iron of the upwards winding machine is contacted with the limiting switch on the step beam, the code value of the encoder is cleared. When the stop iron of the upwards winding machine is contacted with the limiting switch on the preparation station, an initial code value X is recorded. When the upwards winding machine is stopped, an immediate code value Y is recorded. The position offset value delta L of the upwards winding machine and the stop position D of the upwards winding machine are calculated. When the D is larger than the sum of L and the delta L, the upwards winding machine is controlled to retreat for a set distance. When the D is smaller than the difference of the L and the delta L, the upwards winding machine is controlled to move forwards for the set distance. Therefore, the position deviation of the upwards winding machine is controlled to be within +/_50mm, upwards winding time is shortened, the working rate of the device is improved, and the accident that steel coils fall off is avoided.

Description

Hot rolling divides winding apparatus in the spiral automatic centering

Technical field

The utility model belongs to steel rolling automaton field, relates in particular to a kind of automatic centring device of rolling up on the spiral coil of strip that divides for hot rolling.

Background technology

Hot rolling divides the spiral coil of strip to be hung the coil of strip that comes by the volume handlebar by crane and be transported to coil of strip from the entrance step rate and prepare the station and carry out cutting process transporting process need.Go up the volume car in fortune volume way because the position deviation that the position error that mechanical clearance and mechanical friction cause often causes volume handlebar coil of strip to be transported to when preparing on the station is prepared the center at station by hydraulic motor as transmission device.Because the coil of strip position is inaccurate in the position of preparing the station, needs operating personnel manually the coil of strip position to be adjusted; When preparation station center line is too departed from placement coil of strip position, even can cause coil of strip to drop from preparing the station, cause the plant equipment accident that smashes.In addition, on roll up car and receive the instruction that hydraulic motor stops to move after because the heavy inertia that produces of own wt and volume, on roll up car stop motion at once.After last volume car stops, the deviation that the distance between center line of volume car is prepared the station center line in the actual measurement about ± 300mm, the substantial deviation of two center lines cause easily coil of strip from prepare the station and fall or under go on foot operation coil of strip crop and impact.

Summary of the invention

The utility model aim to provide a kind of can automatic accurate centering, the volume time in the saving, improve equipment operation rate, the hot rolling of avoiding coil of strip to drop divides on the spiral coil of strip rolls up automatic centring device.

For this reason, the solution taked of the utility model is:

A kind of hot rolling divides winding apparatus in the spiral automatic centering, comprise CPU and go up the volume car, it is characterized in that, in volume car level run direction encoder is installed, at entrance step rate center line with on the center line of preparing to stand limit switch is set respectively, simultaneously set up function control block (FCB) FC in CPU, encoder, limit switch are connected with function control block (FCB) FC respectively.

Centering method of the present utility model and beneficial effect are:

When last volume car bumper iron touches limit switch on the step rate, the zero clearing of encoder code value; When last volume car moved to its buting iron and touches the limit switch of preparing the station, encoder recorded initial code value; When last volume car was out of service, encoder recorded instant code value, calculated volume car position offset simultaneously and went up volume car actual stop position; Function control block (FCB) FC judges according to value of feedback, and starts automatically location APC function last volume car position is adjusted: it is satisfied imposes a condition, on roll up the position that car stops at permission.

The utility model has been eliminated in the manual adjustment drawback of volume car, has realized the accurate centering of rolling up on the coil of strip, reduces and has avoided the coil of strip accident that drops, and has guaranteed equipment and personal safety; Make deviation that the distance between center line of volume car prepares the station center line by original ± 300mm narrow down to ± 50mm in; And can shorten and go up the volume time, improve equipment operation rate;

Description of drawings

Fig. 1 is that hot rolling divides winding apparatus structured flowchart in the spiral automatic centering.

The specific embodiment

As seen from Figure 1, the utility model hot rolling divides that winding apparatus mainly is at original CPU(central processing unit in the spiral automatic centering) and roll up on the basis of car, in volume car level run direction an incremental encoder has been installed again, be provided with a WLCA32-43 type lead limit switch respectively at entrance step rate center line with on the center line of preparing to stand, in CPU, set up simultaneously function control block (FCB) FC, and encoder is connected with function control block (FCB) FC respectively with two limit switches, realize the automatic centering of coil of strip, accurately go up volume.

Claims

1. a hot rolling divides winding apparatus in the spiral automatic centering, comprise CPU and go up the volume car, it is characterized in that, in volume car level run direction encoder is installed, at entrance step rate center line with on the center line of preparing to stand limit switch is set respectively, simultaneously set up function control block (FCB) FC in CPU, encoder, limit switch are connected with function control block (FCB) FC respectively.
