Specifically, as shown in fig. 2, an electronic tag is provided on the tape surface 11, for example, a tag such as an RFID technology is integrated on the tape surface 11, so that each section of the tape surface 11 has a different identity. The device is provided with an on-line monitoring device 2, an on-line scanner is arranged on the on-line monitoring device 2 to identify the belt surface label, and a metal detector is arranged to identify the metal belt clamping head. The handheld terminal 3 is a handheld area monitoring device, can identify area labels, a worker scans the area labels on two sides of which the belt clamping head needs to be replaced through the handheld terminal 3, then data are transmitted to the online monitoring device 2 or to independent electronic equipment through wireless signals such as WIFI, bluetooth, a fourth-generation mobile information system (4G), a fifth-generation mobile information system (5G) and the like, and step S301 is triggered to obtain label information of a first scanning area obtained by scanning of the handheld terminal 3. Because the tape surfaces have different identity information, each section of tape surface is numbered in sequence by the primary use, namely 00, 01, 02, 03, 04, 05 … … and the like. Each number corresponds to a different information stored in the device. Thus, when the serial numbers of the two continuous scanning belt surfaces scanned by the handheld terminal are acquired from the handheld terminal, the first scanning belt surface is determined according to the serial numbers. Specifically, considering that the scan band surfaces are cyclic numbers, i.e. the numbers are numbered 00 again after the last one, if one of the numbers of two continuous scan band surfaces is the largest number and the other is the smallest number, the scan band surface with the largest number is selected as the first scan band surface, the largest number is the first number, otherwise, the smaller number of the two numbers is selected as the first number, and the corresponding scan band surface is selected as the first scan band surface.
Then, the belt conveyor (i.e. the adhesive tape machine) is started, and step S302 is triggered to control the on-line monitoring device 2 to scan the conveyor belt 11, where the scanned belt surface is the second scanned belt surface.
Then, step S303 to step S304 are executed to calculate and determine the arrival time of the first scanning belt surface to the on-line monitoring device.
Because the tape surfaces have different identity information, each section of tape surface is numbered in sequence by the primary use, namely 00, 01, 02, 03, 04, 05 … … and the like. Each number corresponds to a different information stored in the device. Each section of the belt surface has a length of about L.
Therefore, if the first number is greater than the second number, the distance from the first scanning belt surface to the on-line monitoring device is calculated as follows: d= (M-N-1) ×l, where M is a first number, N is a second number, and L is a tape length;
if the first number is smaller than the second number, calculating the distance from the first scanning belt surface to the on-line monitoring device as follows: d= (k+m-N-1) ×l, where K is the total number of tape surfaces, M is the first number, N is the second number, and L is the tape surface length.
For example: scanning to 04 and 05, i.e. the tape cartridge between them, requires replacement. The first scan belt surface is identified as belt surface number 04. The belt conveyor (i.e., the adhesive tape machine) is started, and if the first belt surface scanned by the online scanner of the online monitoring device 2 is 02, the belt surface numbered 02 is the second scanned belt surface. The distance D between the chuck of the belt to be replaced and the online scanner can be judged according to the number 04 of the first scanning belt surface and the number 02 of the second scanning belt surface.
D＝(04-02-1)×L
The calculation time t for the belt clamp to be replaced to reach the scanner is calculated, and the speed of the conveying belt is V1.
t＝D/V1。
When the 04-number belt surface reaches the on-line monitoring device 2, the belt conveyor starts to decelerate, when the metal detector of the on-line monitoring device 2 scans the metal belt clamping head, the acceleration for decelerating applied to the conveying belt is determined according to the speed of the conveying belt when the belt clamping head to be replaced is detected, and the distance that the belt clamping head reaches the designated position of the dismounting belt clamping head through the mounting point of the on-line monitoring device 2 is known as D 0 The speed of the conveyor belt at this time is known as V, and the deceleration acceleration a and the stop time t of the drive control device are calculated 0 Wherein:
thus, t can be obtained by performing step S307 and step S308 0 ＝2D 0 V and calculating the deceleration acceleration a=v/t 0 。
Then, step S309 is executed to control the drive control device to apply the acceleration for deceleration, which is opposite to the movement direction of the conveyor belt, to the conveyor belt until the conveyor belt stops, and stop the belt chuck to be replaced at the specified position of the removable belt chuck.
The data and the method can realize automatic locating with the clamping head and accurate locating.
The worker can realize positioning by only scanning the adjacent belt surfaces at the position of the designated belt clamping head by using the handheld terminal. The belt conveyor automatic control realizes accurate shut down, and degree of automation is high, and the shutdown position is accurate. According to the embodiment, the electronic tag and the handheld scanning instrument are utilized to realize the positioning of the belt clamping head to be replaced, the on-line monitoring device is utilized to perform secondary positioning on the metal belt clamping head, the accurate positioning of the position of the belt clamping head is realized, the error is not more than 10 cm, and accurate data support can be provided for the driving controller to control accurate parking.
