Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
As shown in fig. 1 to 2, in the present embodiment, an automatic vision inspection correction device for a bag making machine includes an equipment rack, an upper vision inspection lens 1, a lower vision inspection lens 2, an upper buffer linkage swing roller 3, a lower buffer linkage swing roller 4, a swing arm center roller 5, and a servo motor 6, the upper buffering linkage swing roller 3 is positioned at the upper end of the equipment rack, the lower buffering linkage swing roller 4 is positioned at the lower end of the equipment rack, one end of the upper buffering linkage swing roller 3 is hinged with the equipment rack, one end of the lower buffering linkage swing roller 4 is hinged with the equipment rack, the servo motor 6 is arranged on the equipment frame, the end part of the swing arm center roller 5 is connected with the movable end of the servo motor 6, the visual detection upper lens 1 and the visual detection lower lens 2 are respectively installed on the equipment rack, and the visual detection upper lens 1 is located right above the visual detection lower lens 2.
The design is not only suitable for the eight-edge sealing square bottom bag making machine, but also suitable for the three-edge sealing, four-edge sealing, five-edge sealing standing bag and zipper bag making machine.
When the sheet materials are conveyed, the color code of one sheet material is taken as a reference, government deviation data formed by detecting the color code of the upper sheet material 14 and the color code of the lower sheet material 15 is converted into an electric signal to be sent to the servo motor 6, the servo motor 6 controls the swing arm center roller 5 to rotate for a certain angle, the traction length of the non-reference sheet material is changed, the deviation with the reference sheet material is corrected, and finally the color code of the upper sheet material 14 and the color code of the lower sheet material 15 are in the same vertical plane.
The effective shooting range of the upper visual detection lens 1 and the lower visual detection lens 2 is set within 20mm (+/-10 mm), the acquisition precision can reach 0.02mm, the shooting speed is 20 times without birds, and the requirements of high-speed production are completely met. When the deviation value of the upper sheet stock 14 and the lower sheet stock 15 is detected to be within +0.15-10mm, the servo motor 6 positively rotates to send a signal; when the deviation value of the upper sheet material 14 and the lower sheet material 15 is detected to be within-0.15-10 mm, the servo motor 6 reverses signals; when the deviation value of the upper sheet material 14 and the lower sheet material 15 is detected to be within-0.15-0.15 mm, the servo motor 6 does not act, the correction device does not have the opportunity of dislocation when the correction device corrects the deviation value to be within the allowable deviation value, and the correction device is automatically detected and corrected in real time and can always control and maintain the dislocation of the upper sheet material 14 and the lower sheet material 15 in the longitudinal direction to be within the allowable deviation value.
In order to prevent the device from correcting too much, avoid repeated reverse correction and adapt to all film materials with different characteristics, when the deviation value detected by the device is converted to the servo motor 6 for automatic correction, the specific correction value can be set, different deviation values can be set for different correction values, in addition, when the deviation value is too large, the device can also be set for the number of times of non-correction, so that the correction value is not corrected every time detection is carried out, the device can properly select the non-correction, the correction value given every time can be eliminated without generating backlog, and the final correction value is ensured to be corrected in place without being too much.
Furthermore, the device is further designed with an intelligent recognition function, in the correction process, on the basis of setting the number of times of non-repair, if the device detects that the material deviation value of normal regression stays at a certain position and does not move (more than three times) or has the phenomenon of reverse deviation, the device can consider that the correction amount is insufficient, automatic repair can be carried out, the device is not limited by the setting of the number of times of non-repair, and the setting of the number of times of non-repair is effective only on the premise of normally reducing the deviation amount every time. Similarly, in the correction process, on the basis of setting a correction failure time, if the detection shows that the correction speed is too high and exceeds the maximum value (more than three times) of normal regression every time, the device considers that the correction amount is too much, and in order to avoid generating accumulation and finally cause excessive correction, the device can automatically increase the correction failure time and reduce the correction amount so as to ensure that the correction amount in the current period is just corrected to the allowable deviation value.
The upper buffering linkage oscillating roller 3 and the lower buffering linkage oscillating roller 4 respectively play a role in drawing the upper sheet stock 14 and the lower sheet stock 15.
