Description
Technical Field

Background
The processing steps of the aluminum material are mainly as follows: firstly, an aluminum ingot is rolled into a plate and coiled, then the plate is uncoiled, straightened, sheared (or coiled again) and the like by certain mechanical equipment, and finally a finished product is packaged. The aluminum coil 01 is generally placed on a storage table 02 before the next step of processing, and the aluminum coil 01 needs to be transported and placed on a winding drum 08 of an uncoiler to be uncoiled, and the transportation and placement process is called coiling.
In the prior art, the reeling device comprises a storage platform 02, a carrier 05 (an apparatus for carrying an aluminum reel 01, which is controlled by a motor to move in the horizontal direction, and mainly comprises a hydraulic oil cylinder 06 for placing the aluminum reel 01, a bracket 07, a motor and a wheel set), a walking trench reference surface 03, a running track 04 and a hydraulic system. The reeling operation generally adopts manual operation, and the process mainly comprises two steps: the first step is as follows: as shown in fig. 1, a production worker (designated as an operator) operates the carrier 05 to move under the stock table 02, connects the hydraulic cylinder 06 under the bracket 07 of the carrier 05, raises the bracket 07 to hold the aluminum coil 01, and then operates the carrier 05 to move to the reel 08 of the uncoiler; in the process of moving to the uncoiler, another production person (designated as an observer) needs to observe at one side of the aluminum coil 01 in the opposite direction to the moving direction to confirm whether the hollow part of the torus of the aluminum coil 01 is aligned with the winding drum 08 of the uncoiler or not and instruct the operator to adjust the height of the bracket 07 of the trolley, so that the aluminum coil 01 can enter the winding drum 08 correctly, and the equipment and the aluminum coil 01 are prevented from being damaged by collision. The second step is that: as shown in fig. 2, after the aluminum coil 01 enters the uncoiler drum 08, it needs to be placed at the horizontal center of the drum 08, which is commonly called centering.

The winding process of the winding device comprises the following steps: the method comprises the steps of automatic reeling-up start → descending of a bracket of a carrier to the lowest position → retreating of the carrier to a storage table position → ascending of a stopping bracket to the highest position → advancing of the carrier to a height measurement position → descending of the stopping bracket to the lowest position → height measurement of a laser range finder → advancing of the carrier to a width measurement position after completion of height measurement → starting of width measurement of an optoelectronic switch and continuing advancing of the carrier → advancing of the carrier to a central position of a winding drum after completion of width measurement → finishing of advancing and stopping reeling-up of the carrier.
Note that the carriage 05 is set to move forward in the direction of the unwinder drum 08 and set to move backward in the direction of the stocker 02.
In addition, in order to ensure the safety and stability of the operation of the carrier 05, two ends of the operation track 04 of the carrier 05 are respectively provided with a limit switch so as to realize the functions of 'forward in place' and 'backward in place', and the limit switches are used for protecting the movement of the carrier 05 so as to prevent the carrier 05 from leaving the track; meanwhile, two sets of limit switches, namely an ascending switch and a descending switch, are arranged on the carrier 05 and used for detecting and controlling the bracket 07 to ascend to the highest position and descend to the lowest position.
The distance from the laser range finder to the top of the aluminum coil 01 is measured by the laser range finder, and the height measurement operation is set to be started when the bracket 07 of the transport vehicle 05 descends to the lowest position; the width measurement is to measure the width of the aluminum roll 01 in the horizontal direction by switching on and off the photoelectric switch for the next calculation and positioning.
In the embodiment, two technical problems can be solved by applying the coiling device, namely, the positioning of the vertical height of the coiled material is performed to ensure that the central point of the circular ring surface of the coiled material and the central point of the circular shaft of the winding drum 08 of the uncoiler are positioned on the same horizontal plane; the second is the positioning of the carrier 05 or the coil horizontal displacement to ensure that the carrier 05 is accurately positioned to the target position, such as the stock level, the height measurement level and the most important horizontal center position of the roll 08.
The following specifically describes the positioning of the vertical height of the coiled material and the positioning of the horizontal displacement during the coiling process by taking a laser distance meter, an encoder and a photoelectric switch as examples.
Positioning of vertical height
Can realize mathematical operation function through PLC, specifically, when bearing bracket 07 of aluminium book 01 descends to the minimum, PLC begins the height finding operation, at this moment, the data transmission that laser range finder detected to PLC, PLC further calculates aluminium book 01 maximum to laser range finder's distance when 01 and reel 08 are coaxial, PLC controls hydraulic cylinder 06 operation according to this distance in order to realize bracket 07's height control, when the data that laser range finder measured equals the distance that PLC calculated, stop the height control to bracket 07.
Specifically, as shown in fig. 5, the carrier 05 is lowered to the lowest position, and then the vertical positioning is started. The point A is a laser range finder, the point B is the central point of a circular shaft of a winding drum 08, the point C is the top point of an aluminum coil 01 when a bracket 07 of the transport vehicle 05 descends to the lowest position, the point D is the central point of a circular ring surface of the aluminum coil 01, and the point E is the lowest point of the aluminum coil 01 when the bracket 07 of the transport vehicle 05 descends to the lowest position (the point E and a reference surface 03 of a travelling trench of the transport vehicle 05 are on the same horizontal plane). And setting the distance between AE as H, the distance between AB as H, the distance between AC as d and the distance between DE as the radius r of the circular ring surface of the aluminum coil 01. H and H are fixed values, d is a current value measured by the distance meter and is a known quantity, and the radius r is an unknown quantity due to the size of the aluminum coil 01. The aim of height positioning is to make the point D and the point B on the same horizontal plane.
As shown in FIG. 6, point B is located at the same horizontal plane as point D1, and in order to make roll 01 at the target height, the center point of the torus must be located at point D1, and the top point of roll 01 is located at C1. The target value of the positioning is the distance Y between the AC1 at this time, as shown in fig. 6, Y is H-r, and as shown in fig. 5, r is (H-d)/2. Thus, Y ═ H- (H-d)/2. Of course, the above-mentioned operation function can be realized by the PLC programming.
Second, positioning of horizontal displacement
For the positioning of the storage position and the height measurement position, the encoder is adopted, so that the positioning method can count through the encoder, and then the counting point is matched with the actual position through PLC programming, thereby achieving the purpose of positioning.
Because the aluminum coils 01 are different in size and different in width, in order to accurately position the aluminum coils 01 to the central point of the uncoiler winding drum 08 in the horizontal direction, measurement by means of a photoelectric switch and mathematical operation of a PLC are required. As shown in fig. 7 and 8, the S point is set as the zero point of the cart 05, the encoder data is 0 when the cart 05 is at this position, and the cart 05 is 0mm apart on the HMI display screen. The M point is the central point of the winding drum 08, the N point is the central point of the aluminum coil 01, and the aim is to enable the M point to coincide with the N point. In actual production, the center point of the truck 05 on the horizontal line does not necessarily coincide with the center point N of the aluminum coil 01, and therefore, the target horizontal positioning value is the distance X (not shown) between the truck 05 and the S point when the N point of the aluminum coil 01 coincides with the M point. Setting the distance between the M point and the photoelectric switch as L, wherein the distance is a fixed value, when the left OP surface reaches the position of the photoelectric switch in the process that the aluminum coil 01 moves towards the M point, the photoelectric switch is disconnected because the aluminum coil 01 blocks light, and through programming, the PLC automatically records the position of the trolley at the moment, and the position is set as W1 (not marked in the figure); when the right QR surface leaves the position of the photoelectric switch, the light is recovered, the photoelectric switch joint is programmed, and the PLC automatically records the position of the trolley at the moment and sets the position as W2 (which can be understood as the distance from the S point of the carrier 05 when the point 01N of the aluminum coil does not coincide with the point M). From this, the width k of the aluminum coil 01 can be calculated as W2-W1. As can be seen from fig. 8, the target value X ═ L + W2-k/2 ═ L + W2- (W2-W1)/2. Of course, the above operation process can be realized by PLC.
The aluminum product production equipment provided by the invention comprises the coiling device described in the specific embodiment; other parts of the aluminum production equipment can be referred to the prior art and are not expanded.
