And 2, the electric tray roller way type conveying line equipment is provided with three rows of driving rollers. The detecting heads of the two sets of infrared distance measuring instruments 1 are in a face-to-face state. The two electromagnetic valves at the inner side ends and the air inlet ends of the two electromagnetic valves at the outer side ends of the cylinders 34 of the two sets of centering equipment are respectively connected with a gas output pipe of an air compressor (not shown in the figure) in parallel through a pipeline joint.
As shown in figures 1, 2 and 3, the distance (15cm) between the front side ends of the push plates 33 of the two sets of centering devices and the infrared range finder 1 is smaller than the front-back length of the tray 4. When the piston rod of the cylinder 34 of the two sets of centering equipment push plates moves to the rear dead center in the cylinder, the distance between the left side and the right side is larger than the left-right width of the tray 4, and when the piston rod of the cylinder moves to the front dead center in the cylinder 34 of the two sets of centering equipment push plates 33, the distance between the left side and the right side is slightly larger than the left-right width of the tray 4 by 1 cm. Two sets of centering equipment 3 can also adopt one set, install in frame one side, and the fixed plate is installed to the corresponding position in frame opposite side (during operation, the push pedal of one set of centering equipment promotes the tray and moves the contact fixed plate to the opposite side, and then realizes purpose placed in the middle).
As shown in fig. 1, 2 and 3, when the plurality of trays 4 are continuously conveyed forward on the driving roller 21 of the electric tray roller conveyor line equipment 2, the front end tray 4 passes between the push plates 33 of the two sets of centering equipment and then between the detecting heads of the two sets of infrared range finders 1. When the tray is positioned on the transmission roller 21 in front and does not deflect left and right (or the deflection angle is very small, the normal work of the next procedure cannot be influenced), the distance between the left side end and the right side end and the distance between the detecting heads of the two sets of infrared distance measuring instruments 1 exceed 3cm, because the distance between the detecting heads of the infrared distance measuring instruments and the tray is smaller than the threshold distance set in the infrared distance measuring instruments, the two sets of infrared distance measuring instruments 1 do not output high level signals to enter a PLC signal input end, the PLC does not control the electromagnetic valve of the cylinder to work, so the push plates of the two sets of centering equipment do not move, and the tray 4 normally moves to the next station towards the front end. When the tray is positioned on the transmission roller 21 and has an overlarge leftward or rightward deflection angle, the distance between one side of the front two side ends of the tray 4 and one of the detecting heads of the two sets of infrared distance measuring instruments 1 is less than 3cm, and because the distance between the detecting head of one set of infrared distance measuring instrument and the tray is higher than the threshold distance set in the infrared distance measuring instrument, one set of infrared distance measuring instruments 1 can output high-level signals to enter a PLC signal input end. In practical situations, after a high level signal is input to any one signal input end of the PLC, the PLC can simultaneously control the electromagnetic valves at the outer side ends of the cylinder bodies of the two sets of centering equipment to be powered on (the electromagnetic valves are one-position two-way electromagnetic valves, an exhaust port is closed and an air inlet is opened when the power is on), so that compressed air output by the air compressor enters the outer side ends of the cylinder bodies of the two sets of centering equipment, air in the inner side ends of the cylinder barrels is exhausted from electromagnetic valve exhaust ports at the inner side ends of the cylinder bodies of the two sets of centering equipment (the exhaust port is opened and the air inlet is closed when the electromagnetic valves are not powered on), the piston rods of the two sets of centering equipment respectively drive the push plates 33 to move inwards, the distance between the two sets of centering equipment push plates 33 is reduced, the distance between the two push plates 33 is only 1cm wider than the left and right width of the tray 4, and thus the cylinders of the two sets of centering equipment can effectively push the tray to be positioned at the center position on the driving roller through the push plates 33 (the piston rods of the cylinders stop outputting power after the piston rods of the PLC moves to the front dead center) . When the PLC controls the push plates 33 of the two sets of centering equipment to move inwards to the dead point to correct the angle of the tray 4, the PLC immediately controls the electromagnetic valves at the inner side ends of the cylinder bodies of the two sets of centering equipment to work by electrifying (the electromagnetic valves are one-position two-way electromagnetic valves, when electrified, the exhaust port is closed, the air inlet is opened), then compressed air output by the air compressor enters the inner side ends of the cylinder bodies of the two sets of centering equipment, air in the outer side end of the cylinder barrel is exhausted through the exhaust port of the electromagnetic valve at the outer side end of the cylinder body of the two sets of centering equipment (when the electromagnetic valves are not electrified, the exhaust port is opened, the air inlet is closed), thus, piston rods of the cylinders of the two sets of centering equipment respectively drive the push plates 33 to move outwards, the distance between the two sets of centering equipment push plates 33 is enlarged, the distance between the two sets of centering equipment push plates 33 is restored to an initial state, and preparation is made for pushing the next tray to center (after the piston rods of the cylinders move to a rear dead point, the PLC stops outputting power supplies). Through the combined action of the mechanisms, when the tray is conveyed forwards on the driving roller 21 of the electric tray roller way type conveying line equipment 2, as long as the position deviates, two sets of centering equipment can center the tray, so that the subsequent mechanical equipment or manual work for stacking the tray is effectively ensured, and the mechanical equipment can smoothly take the tray down from the rotating roller.
