The working process and the working principle of the automatic wheel information acquisition and boxing production line are as follows:

(1) Is conveyed on a wheel conveying line 29 of the wood pallet blank

1 fork truck places the wheel blank on wooden block dish blank wheel transfer chain 29, installs No. 1 sensor at wooden block dish blank wheel transfer chain 29 upside side, and No. 1 sensor priority is higher than No. 2 sensor, and when fork truck got into safe district, wooden block dish blank wheel transfer chain 29 suspended.

And then the wheel blank is conveyed to an automatic wheel information acquisition system for hoisting, overturning, code reading and centering. The automatic wheel information acquisition system (hoisting truss 20) is provided with a No. 2 sensor, whether wheels exist on the centering device rotating platform 11 or not is detected, if yes, the wood pallet blank wheel conveying line 29 suspends working, otherwise, the wood pallet blank wheel conveying line 29 normally works, and materials are fed onto the centering device rotating platform 11.

(2) Centering code scanning recognition system-centering process

A. Centering: because the wheels (at most 4) on the wooden pallet of the centering device rotating platform 11 are not necessarily concentric when being superposed together, and incline, the grabbing work of the following wheels can be influenced, so that the centering work is firstly carried out before grabbing and overturning, and the centering is carried out before grabbing each wheel, so that the lifting sliding table 21 is ensured to move according to the centering position, and corresponding blank wheels are accurately grabbed, the grabbing accuracy is improved, and after all the wheels on each wooden pallet are grabbed, the numerical control cross sliding table 10 returns to the original position.

The centering device mainly comprises a rotating platform 11 and a cross sliding table 10.

The cross sliding table 10 consists of an X-axis moving guide rail and a Y-axis moving guide rail, and the cross sliding table 10 is controlled by a servo motor to move in the X direction and the Y direction respectively, so that the position of the wheel blank can be adjusted.

The rotary motor and the reducer of the rotary table 11 cooperate to control the big gear and the small gear of the rotary bearing, so that the rotary platform can rotate 360 degrees.

B. And (3) photographing: the camera 25 is fixed on the cylinder push rod, is fixed on the linear module 2 through a cylinder connecting plate, and can move up and down along with the change of the wheel position. The camera 25 is a CCD camera.

The centering device firstly takes a picture of the uppermost wheel of the wooden pallet through the camera 25, and the system stores the coordinate data of the standard position (reference number 39 in fig. 19). And comparing the actual coordinate position (reference number 40 in fig. 19) of the wheel obtained by photographing with a standard position, calculating direction data needing to be adjusted through a computer, transmitting the data to the numerical control cross sliding table 10, adjusting the X direction and the Y direction of the numerical control cross sliding table 10 through the control of a servo motor, and finally moving the wheel to the position of a theoretical coordinate point.

(3) Centering code scanning identification system-card reading process

The side surface of each wheel blank is adhered with a magnetic code and a bar code, the magnetic code and the bar code store the information of the wheel, but before turning and boxing, the magnetic code and the bar code of the wheel on the wood supporting plate are not in the same horizontal plane, namely not on the same straight line, which causes troubles for a series of next boxing, and because the quality of the wheel is overweight, the positions of the magnetic code and the bar code are adjusted by manpower, so that the production efficiency is reduced, therefore, the positions of the magnetic code and the bar code are adjusted by a magnetic code and bar code identification device and a wheel rotating sliding table before loading, the cost is saved, and the production efficiency is improved.

The magnetic code recognizer 26 and the bar code recognizer 27 are fixed on a cylinder push rod, and the push rod is connected with the linear module 2 and can move horizontally along the X axis and vertically up and down along the Z axis.

After the centering of the wheel blank on the uppermost surface of the tray is finished, the magnetic code recognizer 26 starts to work, the centering device rotating platform 11 rotates simultaneously, when the wheel magnetic code is recognized by the magnetic code recognizer 26, the rotating platform 11 stops immediately, and the bar code recognizer 27 scans the bar code; when the rotating platform rotates for 360 degrees, no magnetic code is found, the scanning is regarded as failed, the system prompts an alarm to request manual intervention, and the production line continues to work after the wheel type number is manually input.

(4) Hoisting truss 20 and hoisting sliding table 21-hoisting placing process

The centering code-scanning recognition system 22 obtains the central position of the uppermost blank wheel, and then adjusts the position of the hoisting sliding table 21 to the determined central position according to the central position, so as to ensure that the uppermost blank wheel is accurately grabbed.
