The front swing arm 131 includes a top 1313 and a bottom 1314, and the first end 1243 of the front triangle 1242 is hinged with the bottom 1314 of the front swing arm 131, so that the front triangle 1242 drives the front swing arm 131 to turn over from a horizontal position to an upright position or from an upright position. The position flips to the horizontal position. Correspondingly, the structure of the rear hydraulic device 122 is the same as that of the front hydraulic device 121 , and the rear hydraulic device 122 drives the rear swing arm 132 to turn over from the horizontal position to the upright position or from the upright position to the horizontal position.

As shown in FIG. 2 , the transmission mechanism 140 is used to deliver the end frame 160 , and the transmission mechanism 140 is connected with the turning mechanism, so that the end frame 160 can be placed on the swing arm device through the transmission of the transmission mechanism 140 . The transmission mechanism 140 includes a transmission chain 141 and a transmission base 142, and the transmission base 142 is fixed on the ground so that the transmission chain 141 does not move randomly. The end frame 160 is placed on the transfer chain 141, and the transfer chain 141 is connected with the turning mechanism along the conveying direction, so that the end frame before processing can be placed on the front swing arm through the transfer chain, and the processed end frame can be conveyed through the transfer chain. The chain is sent to other stations.

The conveying process of the end frame 160 via the transport turning mechanism 100 is as follows:

As shown in FIG. 4A , both the front swing arm 131 and the rear swing arm 132 are in a horizontal position. The end frame 160 is placed on one end of the transmission chain 141; the transmission chain 141 starts to run, thereby driving the end frame 160 to move in the direction of the forward swing arm 131; The first end 1311 moves; the end frame 160 moves to the first end 1311 of the front swing arm 131 , and the transportation stops when the distance between the end frame 160 and the first contact surface 153 of the front adjustable pallet 151 is 10mm-20mm.

As shown in Figure 4B, the rear hydraulic cylinder 126 operates to lift the rear triangular plate 1272, and the rear triangular plate 1272 drives the rear crank arm 1271 to rotate, thereby driving the rear swing arm 132 to turn from a horizontal position to a position of 85 degrees; when the rear swing arm 132 is in At the 85 degree position, the rear hydraulic cylinder 126 and the rear crank arm 1271 support the rear swing arm 132 .

As shown in Figure 4C, the front hydraulic cylinder 123 operates to lift the front triangular plate 1242, and the front triangular plate 1242 drives the front crank arm 1241 to rotate, thereby driving the front swing arm 131 to turn from a horizontal position to a position of 95 degrees, and the front swing arm 131 supports the end The frame 160 is turned over at the same time, and the front adjustable supporting plate 151 supports the end frame 160 during the turning over; when the front swing arm 131 is at a position of 95 degrees, the front hydraulic cylinder 123 and the front crank arm 1241 support the front swing arm 131; Plates 151 and rear adjustable supporting plates 152 are arranged alternately. The front adjustable supporting plates 151 and the rear adjustable supporting plates 152 jointly support the end frame 160. Since the front swing arm 131 turns over to reach 95 degrees, the end frame 160 is subjected to the effect of gravity. The frame 160 slides toward the rear swing arm 132 until the rear adjustable bracket 152 fully supports the end frame 160 , and the first surface 161 of the end frame 160 contacts the rear swing arm 132 .

As shown in FIG. 4D , the rear hydraulic cylinder 126 rotates, driving the rear crank assembly 127 to rotate, thereby driving the rear swing arm 132 to turn from the 85 degree position to the horizontal position, and the end frame 160 to turn to the horizontal position accordingly. During the overturning process, the first surface 161 of the end frame 160 is in contact with the top 1323 of the rear swing arm 132 , that is, the rear swing arm 132 supports the end frame 160 . The rear swing arm 132 is flipped to a horizontal position and separated from the end frame 160 .

As shown in Figure 4E, the front hydraulic cylinder 123 is running, driving the front crank assembly 124 to rotate, thereby driving the front swing arm 131 to flip from a 95-degree position to a horizontal position; the transmission chain 141 continues to drive the end frame 160 to move, driving the end frame 160 from the rear The swing arm 132 moves toward the other end of the transmission chain 141 .

In this way, the turning mechanism and the transmission mechanism are combined, the front swing arm and the rear swing arm are arranged on the same straight line along the conveying direction, and the transmission chain of the conveying mechanism is connected to the turning mechanism along the conveying direction, so that when the conveying mechanism conveys the end frame, Synchronous overturning mechanism, skillfully set the overturning mechanism in the transmission mechanism. When the end frame 160 is on the transmission mechanism 140, the operator can assemble the parts of the end frame 160, so that the assembly time can be saved.

Further, when the width of the end frame changes, in order to ensure the constant distance between the center of the fetal position of each component of the transmission mechanism, the position of the adjustable supporting plate can be adjusted to ensure that the center of the fetal position remains unchanged. Of course, if the width of the end frame The position of the adjustable supporting plate does not need to be adjusted when the change is small, and the position of each component has no influence on the tire position of each component during the subsequent conveying and turning process.

When the front swing arm 131 and the rear swing arm 132 are in the horizontal position, the top surface of the front swing arm 131 and the top surface of the rear swing arm 132 can be lower than the transmission chain 141, so that the transmission of the end frame 160 is not affected. When the adjustable pallet is disassembled from the swing arm, the end frame can pass through the swing arm and support directly from the transmission chain without turning over the swing arm, so as to meet the production needs of some special box types without turning over. During the turning process of the front swing arm and the rear swing arm, the turning position and turning angle can provide signals to the controller (PLC) through the sensor, so as to realize the automatic control and adjustment of the hydraulic device.

In this way, the transmission and turning mechanism does not need other auxiliary facilities to jointly operate the conveying and turning of the end frames, the original facilities of the production line will not be changed, and online turning can be realized, and the transmission and turning mechanism will not affect the normal transportation of the end frames. When there is no need to overturn, only the adjustable support plate needs to be disassembled, and the end frame can pass through the transmission overturning mechanism. The flipping process of the front swing arm and the rear swing arm only takes 1 minute, which is far less than the production beat. The overturning process is controlled by a controller (PLC), which provides hydraulic power and realizes the automatic control of the overturning process, which not only reduces labor intensity, but also saves labor. And the design load of the transmission turning mechanism is 1 ton, which can adapt to most of the special box end frames. The transmission and turning mechanism only touches the corner column part of the end frame during the turning process, and does not need to go through the process of changing production, which greatly reduces labor intensity and speeds up the speed of changing production.
