At least one of the first lateral chain conveyor 30, the first longitudinal chain conveyor 40, the second lateral chain conveyor 50, the second longitudinal chain conveyor 60, and the third lateral chain conveyor 70 is provided with a rotating device 90 between the two transfer chains 80. In this embodiment, two conveying chains 80 are disposed in each chain conveyor; since the rotating device 90 is disposed between the two transfer chains 80 of the two second lateral chain conveyors 50 on the far right side, the door panel edge banding rotary conveying system according to the present application is provided with two rotating devices 90. Of course, in other embodiments, only one rotation device 90 may be provided, or three rotation devices 90 may be provided.

As shown in fig. 5 or 8, the rotating device 90 includes a lift driver, a lift base 91 driven to lift by the lift driver, a rotation driving source 92 mounted on the lift base 91, a transmission unit, a rotary table 93, and an adsorption unit mounted on the rotary table 93, wherein the rotation driving source 92 is connected to the rotary table 93 through the transmission unit, drives the rotary table 93 to rotate, the rotary table 93 is disposed below the door panel 10, and is used for supporting the door panel 10, and the adsorption unit is used for downwardly adsorbing the door panel 10.

The working principle of the door plate edge sealing rotary conveying system is as follows: the door panel edge banding rotary conveying system simultaneously conveys a plurality of door panels 10 which are distributed at equal intervals along the conveying direction, the door panels 10 are generally rectangular, and four edges of the door panels need edge banding processing by an edge banding machine 20. For one door panel 10 of the plurality of door panels 10: the first door panel 10 is fed rightward into the edge banding machine 20 by the third transverse chain conveyor 70, and the edge banding machine 20 moves the door panel 10 rightward while finishing edge banding of one short side of the door panel 10. Second, the door panel 10 is successively transferred rightward by the first lateral chain conveyor 30, forward by the first longitudinal chain conveyor 40, and leftward by the second lateral chain conveyor 50; when the sensor senses that the door plate 10 reaches the rotating device 90 at the rightmost second transverse chain conveyor 50, the lifting driver acts to drive the lifting seat 91 to move upwards, the lifting seat 91 drives the rotating table 93 to move upwards together, the rotating table 93 rises upwards from between the two conveying chains 80 of the second transverse chain conveyor 50, and the rotating table 93 lifts the door plate 10 conveyed by the second transverse chain conveyor 50 upwards; the rotation driving source 92 is operated to drive the rotation table 93 to rotate 90 °, and the rotation table 93 drives the door panel 10 supported by the rotation table to rotate 90 °. Third, the lifting driver resets, the lifting seat 91 is driven to move downwards, the lifting seat 91 drives the rotary table 93 to move downwards together, the rotary table 93 moves downwards to the lower part of the conveying chain 80, and the door panel 10 is supported by the conveying chain 80 of the rightmost second transverse chain conveyor 50 again and is transferred leftwards. Fourth, when the sensor senses that the door panel 10 reaches the rotating device 90 at the second lateral chain conveyor 50 of the second right-hand side, the rotating device 90 rotates the door panel 10 by 90 ° again, so that two rotating devices 90 rotate the door panel 10 by 180 °. The fifth door panel 10 subjected to 180-degree reversing is sequentially transferred leftwards by the rest of the second transverse chain conveyors 50, backwards by the second longitudinal chain conveyors 60 and rightwards by the third transverse chain conveyors 70, and then enters the edge banding machine 20, and the edge banding machine 20 banding the other short side of the door panel 10. Sixthly, the door panel 10 is continuously transferred, 90 degrees of reversing are carried out on the door panel 10 by the rotating device 90 when the door panel passes through the first rotating device 90, and the door panel enters the edge banding machine 20 after 90 degrees of reversing, so that the edge banding machine 20 carries out edge banding on one long side of the door panel 10. Seventh, the door panel 10 is continuously transferred, 90 degrees of reversing is performed on the door panel 10 by the rotating device 90 when the door panel passes through the first

rotating device

90, 90 degrees of reversing is performed on the door panel by the rotating device 90 when the door panel passes through the second rotating device 90, 180 degrees of reversing is performed on the door panel, and the door panel enters the edge banding machine 20, so that the edge banding machine 20 carries out edge banding on the other long side of the door panel 10. In this way, the door panel 10 is conveyed by the door panel edge banding rotary conveying system, and enters and exits the edge banding machine 20 four times in different directions, so that the edge banding machine 20 seals four edges of the door panel 10 one by one.

To sum up, the door panel edge sealing rotary conveying system that this application relates to carries and can carry the polylith door panel 10 simultaneously, and can make a round trip to carry same door panel 10 to change the angle of door panel 10 through rotary device 90 in the transportation process, make same door panel 10 can pass in and out the bag sealer 20 with different positions many times, thereby carry out the banding one by bag sealer 20 to four edges of this door panel 10, accomplish door panel edge sealing processing from this. In particular, in the process of rotating the door panel 10 and reversing the door panel 10, the rotating device 90 acts on the adsorption unit, the adsorption unit adsorbs the door panel 10 downwards, and the door panel 10 is reliably held on the rotary table 93, so that the door panel 10 which is rotated and conveyed at high speed is realized, the door panel 10 is prevented from sliding relative to the rotary table 93, and the accuracy of the position of the door panel 10 when entering the edge banding machine 20 is ensured. In the application, the direction of the door 10 is consistent with the gravity direction of the door 10 by the adsorption unit, so the gravity of the door 10 can assist the door 10 to be kept on the rotary table 93, and the rotating device 90 utilizes the gravity of the door 10 to avoid the gravity of the door 10 to be overcome when the door 10 is adsorbed by the adsorption unit, namely, the door 10 is reliably kept on the rotary table 93 by the adsorption unit and the gravity of the door 10, on one hand, the door 10 which is carried at high speed is rotated, namelyRealizes high-speed conveying of the door plate 10, on the other hand, can greatly reduce the output power of the adsorption unit, correspondingly reduces the electricity cost of the adsorption unit and reduces CO ₂ Meets the emission reduction requirement. Finally, the door plate edge sealing rotary conveying system has the advantages that the door plate 10 is conveyed at low cost, 50-100 m/min of high-speed conveying can be realized, the edge sealing speed of the edge sealing machine 20 can be improved to 25-40 m/min, the edge sealing period is shortened, and the production efficiency of the door plate 10 is greatly improved.

Further, in the door panel edge banding rotary conveying system, the first longitudinal chain conveyor 40 and the second longitudinal chain conveyor 60 are integrally liftable, so that the first longitudinal chain conveyor 40 can be well engaged with the first transverse chain conveyor 30 and the second transverse chain conveyor 50, and the second longitudinal chain conveyor 60 can be well engaged with the second transverse chain conveyor 50 and the third transverse chain conveyor 70.

Further, since the door panel 10 is conveyed at a high speed, the door panel 10 may be inclined before entering the edge sealer 20, particularly when the door panel 10 enters the edge sealer 20 in a state of sealing a short side. In order to avoid this, as shown in fig. 2 to 4, in the third lateral chain conveyor 70 disposed at the conveying end, a plurality of conveying chains 80 thereof are in one-to-one correspondence with independent driving sources, each of which is individually controlled. In this way, in the third lateral chain conveyor 70, the conveying speed of the rear side conveying chain 80 thereof with the sealer 20 is kept identical to the sealing speed of the sealer 20, but the conveying speed of the front side conveying chain 80 may be greater than or less than the sealing speed of the sealer 20. Based on this, when the sensor detects that the front end of the door panel 10 conveyed by the third lateral chain conveyor 70 is inclined rightward, the independent driving source corresponding to the front conveying chain 80 is controlled to reduce the conveying speed of the front conveying chain 80, so that the conveying speed of the front conveying chain 80 is smaller than the edge sealing speed of the edge sealing machine 20 until the door panel 10 is aligned and does not incline. Similarly, when the sensor detects that the front end of the door panel 10 conveyed by the third transverse chain conveyor 70 is inclined to the left, the sensor controls the independent driving source corresponding to the front conveying chain 80 to increase the conveying speed of the front conveying chain 80, so that the conveying speed of the front conveying chain 80 is greater than the edge sealing speed of the edge sealing machine 20 until the door panel 10 is aligned and does not incline. Finally, the door plate 10 conveyed at high speed is effectively prevented from tilting when entering the edge bonding machine 20, the door plate 10 can be correctly and stably put into the edge bonding machine 20 while high-speed conveying is ensured, and subsequent commodity complaints are eliminated.

Preferably, as shown in fig. 2 to 4, the third transverse chain conveyor 70 includes a frame, a first motor 151, a second motor 152, and a first driving sprocket 153, a second driving sprocket 154, a first driven sprocket 155, and a second driven sprocket 156 all rotatably mounted to the frame, the first motor 151 and the second motor 152 being two independent driving sources; the first motor 151 drives the first driving sprocket 153 to rotate, and the rear side transmission chain 80 is sleeved on the peripheries of the first driving sprocket 153 and the first driven sprocket 155; the second motor 152 drives the second driving sprocket 154 to rotate, and the front side transmission chain 80 is sleeved on the outer circumferences of the second driving sprocket 154 and the second driven sprocket 156. Thus, the first motor 151 controls the turning motion of the rear side conveyor chain 80 alone, and the second motor 152 controls the turning motion of the front side conveyor chain 80 alone.

Further, as shown in fig. 3 and 4, in the third transverse chain conveyor 70 disposed at the conveying tail end, a plurality of limiting blocks 130 are fixed on the outer surface of each conveying chain 80, and the limiting blocks 130 are distributed at equal intervals along the circumferential direction of the conveying chain 80; in this embodiment, the number of the limiting blocks 130 is two. The limiting block 130 is used for effectively separating the plurality of door panels 10 conveyed by the door panel edge sealing rotary conveying system; the stopper 130 can control the sequential feeding of the plurality of door panels 10.

Further, as shown in fig. 9 and 10, the outer end of each link plate in each conveyor chain 80 is fixed with a non-slip mat 140, the non-slip mat 140 is a rubber mat, and the non-slip mat 140 is in direct contact with the lower surface of the door panel 10, so that the friction between the conveyor chain 80 and the door panel 10 is increased, the door panel 10 can be reliably held on the conveyor chain 80, slipping of the door panel 10 is avoided, and accurate high-speed conveying of the door panel 10 is ensured.

Further, among the first lateral chain conveyor 30, the first longitudinal chain conveyor 40, the second lateral chain conveyor 50, the second longitudinal chain conveyor 60, and the third lateral chain conveyor 70, each chain conveyor is provided with a plurality of sets of floating support units arranged at intervals along the conveying direction of each conveying chain 80 below each conveying chain 80 thereof. As shown in fig. 9 and 10, each set of floating support units includes an elastic compression element 110 extending up and down, and an upper portion of each conveyor chain 80 directly or indirectly acts on an upper end of the elastic compression element 110, and a lower end of the elastic compression element 110 is fixed. In this way, under the action of the door panel 10 conveyed by the conveying chain 80, the compression degree of the elastic compression element 110 can be self-adapted to the curve radian of the lower surface of the door panel 10, so that the part of the conveying chain 80 contacted with the door panel 10 can be up-and-down fluctuated, the height of the conveying chain is self-adapted to the rugged surface of the lower surface of the door panel 10, namely, the rugged surface of the lower surface of the door panel 10 is relatively absorbed, and finally, the part of the conveying chain 80 contacted with the door panel 10 is closely attached to the lower surface of the door panel 10, so that a larger contact surface is ensured between the door panel 10 and the conveying chain 80, friction between the door panel 10 and the conveying chain is increased, sliding and inclination of the door panel 10 are avoided, and the door panel 10 is accurately conveyed at a high speed, and the conveying device is particularly suitable for conveying an upper convex door panel 101 or a lower concave door panel 102 with the lower surface being non-planar at a high speed.

Preferably, as shown in fig. 9 to 12, each set of floating support units further comprises a chain bracket 120, the chain brackets 120 being in abutting engagement with the upper strand portion of the conveyor chain 80; the elastic compression elements 110 in each group of floating support units are two and are both fixed at the lower end of the chain support 120, a channel for allowing the lower section of the transmission chain 80 to pass through is formed between the two elastic compression elements 110, and the transmission chain 80 acts on the upper end of the elastic compression elements 110 through the chain support 120; the lower ends of the elastic compression elements 110 are fixed to the frames of the respective chain conveyors. When each chain conveyor conveys the upper cam plate 101, as shown in fig. 9, the elastic compression element 110 is less compressed at the intermediate position of the upper cam plate 101, and the height of the corresponding conveying chain 80 of the portion is higher; at the front and rear ends of the upper convex door plate 101, the elastic compression element 110 is more compressed, the height of the conveying chain 80 corresponding to the part is lower, the extension curve of the upper section part of the conveying chain 80 is basically consistent with the curve radian of the lower surface of the upper convex door plate 101, the conveying chain 80 is well attached to the lower surface of the upper convex door plate 101 and the warping of the lower surface of the self-adaptive upper convex door plate 101, the contact area of the upper convex door plate 101 and the lower convex door plate is large, the friction force between the upper convex door plate 101 and the lower convex door plate is increased, the upper convex door plate 101 is prevented from sliding, and the upper convex door plate 101 is conveyed at high speed.
