The cylinder body of the second retreating cylinder 6243 is fixedly connected with the second cylinder mounting plate 6241, and the rod end of the piston rod of the second retreating cylinder 6243 is fixedly connected with the sliding mounting block 6242. A washboard 6244 is arranged at the left side of the sliding mounting block 6242, the washboard 6244 is connected with the sliding mounting block 6242 in a sliding manner through a sliding component, and the washboard 6244 can slide back and forth relative to the sliding mounting block 6242. A washboard cylinder 6245 used for driving the seat plate to slide back and forth is arranged between the washboard 6244 and the sliding mounting block 6242, a cylinder body of the washboard cylinder 6245 is fixedly connected with the sliding mounting block 6242, and a rod end of a piston rod of the washboard cylinder 6245 is fixedly connected with the washboard 6244.

Further, as shown in fig. 21, the second cylinder mounting plate 6241 is obliquely arranged right downward, and correspondingly, the second unseated cylinder 6243 is also obliquely arranged right downward. The reason for this is that after the auxiliary feeding device 6 conveys the sheet material to the lower side of the pressing wheel of the first edge bonding machine 31, the sheet material moves downstream in the edge bonding process by the power of the first edge bonding machine 31 itself, and at this time, the washboard 6244 will form a barrier to the movement of the sheet material, so that the washboard 6244 needs to be retracted downward to the lower side of the sheet material, so that the sheet material can smoothly move downstream. If the washboard 6244 is moved back vertically, the washboard 6244 will press the board, which may affect the edge sealing. The scheme adopts an inclined arrangement mode, and the washboard 6244 can move downstream while moving downwards, so that the advancing continuity of the plate can be ensured, and the plate is prevented from being extruded.

As a specific implementation manner, in this embodiment, the sliding mounting block 6242 is in a direct trapezoidal structure, the inclined surface of the sliding mounting block 6242 is located on the left side and is in a vertical state, an installation groove for installing the washboard cylinder 6245 is arranged on the bottom surface of the sliding mounting block 6242, the installation groove includes a vertical surface, and the washboard 6244 is fixedly arranged on the vertical surface.

As shown in fig. 18 and 20, the first carriage 62 is provided with a second carriage 64 that is slidable in the left and right directions with respect to the first carriage 62, and a second driving member for driving the second carriage 64 to move in the left and right directions with respect to the first carriage 62 is provided between the first carriage 62 and the second carriage 64.

As shown in fig. 22, the second carriage 64 includes a bottom plate 641, and second sliders 6411 are fixedly disposed at front and rear ends of a lower surface of the bottom plate 641. As shown in fig. 21, two fixing beams 6216 extending in the left-right direction are disposed above the square frame of the first carriage 62, and both ends of the mounting beam 1111 are fixedly connected to the square frame through support blocks 6217, respectively. Preferably, a reinforcing beam 6212 is provided between the two fixing beams 6216. A second guide rail 623 matched with the second slider 6411 is fixedly arranged on the upper side surface of the fixed beam 6216.

As shown in fig. 21 and 22, the second driving member is located in a clamping cylinder 65 disposed between the first carriage 62 and the second carriage 64, a cylinder body of the clamping cylinder 65 is fixedly connected to the square frame of the first carriage 62, a connecting seat 6412 is fixedly disposed on a lower side surface of the bottom plate 641, and a rod end of a piston rod of the clamping cylinder 65 is fixedly connected to the connecting seat 6412.

As shown in fig. 22, a lifting plate 642 is disposed above the bottom plate 641, and the lifting plate 642 is slidably connected to the bottom plate 641, and the lifting plate 642 can slide up and down relative to the bottom plate 641. A second elevation cylinder 643 for driving the elevation plate 642 to slide up and down is disposed between the elevation plate 642 and the bottom plate 641. As a specific implementation manner, two second elevating cylinders 643 are disposed between the bottom plate 641 and the elevating plate 642 in the embodiment, and are respectively located at the front and the rear sides. The second lifting cylinder 643 adopts a cylinder with a guide rod.

As shown in fig. 18, the lifting plate 642 is provided with first clamping rods 644 corresponding to the positioning pressing heads 6253 in a one-to-one manner, the first clamping rods 644 are fixedly provided with first supporting plates 6441 extending to the right side, and the suspended end of the first supporting plates 6441 is provided with a guide inclined surface.

As shown in fig. 13 and 15, in the actual production line arrangement, when the first carriage 62 is located at the left-side limit position (upstream limit position, i.e., when moving to the most upstream), the horizontal conveying region of the second conveying assembly 231 of the loading device 2 extends to the downstream side of the positioning ram 6253, i.e., the curved portion of the first conveyor belt 1162 is located completely at the downstream side of the positioning ram 6253.

The reason for this is that when the sheet material is transported on the feeding device 2, the first clamping rod 644 is in a retracted state, i.e. below the sheet material, and the first supporting plate 6441 cannot support the sheet material at this time, and only the first conveyor 1162 of the feeding device 2 supports the sheet material. At this time, if the bent portion of the first conveyor 1162 is located on the upstream side of the positioning ram 6253, when the plate material is conveyed to the positioning ram 6253, a partial region of the plate material tends to be located above the bent portion of the first conveyor 1162, and these portions are suspended. When the width of the sheet material is relatively narrow (when the diameter of the sheet material is equal to the diameter of the first driven pulley of the second conveying unit 231), the sheet material may be unstable and may be easily overturned.

Further, as shown in fig. 18 and 22, a plurality of second clamping rods 645 corresponding to the washboard 6244 are disposed on the lifting plate 642. As a specific implementation manner, the lifting plate 642 of this embodiment is provided with three second clamping rods 645 corresponding to the washboards 6244.

Further, as shown in fig. 21 and 22, the top ends of the first and second clamping bars 644 and 645, and the free end of the positioning arm 62531 are provided with a roller 66. This reduces the frictional resistance of the washboard 6244.

Further, as shown in fig. 21, a positioning baffle is further disposed between the two ear plates on the ear seat 6252, and the positioning baffle is located on the left side of the positioning ram 6253. The positioning baffle is provided with a positioning column (not shown in the figure), and the positioning column is fixedly connected with the positioning baffle in a threaded connection mode. When the left side surface of the positioning arm 62531 of the positioning pressure head 6253 is pressed against the right end surface of the positioning column, the positioning arm 62531 of the positioning pressure head 6253 is in a vertical state.

Furthermore, a buffer (not shown in the figure) is arranged on the positioning baffle.

Further, since a plurality of the limiting assemblies are arranged in a dispersed manner, the second conveying assemblies 231 in the feeding device 2 can be staggered with the limiting assemblies. However, the washboard 6244 is a flat plate, and therefore, the washboard and the second conveying assembly 231 of the feeding device 2 cannot be distributed in a staggered manner, and the second conveying assembly 231 of the feeding device 2 can only extend to the left side of the washboard 6244. In this way, the curved portion of the first conveyor belt 1162 of the second conveyor assembly 231 corresponding to the washboard 6244 tends to be located on the upstream side of the washboard 6244. Thus, when a plate with a smaller length is conveyed, only a few second conveying assemblies 231 corresponding to the washboards 6244 may be used for supporting, and at this time, if the width of the plate is narrower (corresponding to the diameter of the first driven pulley of the second conveying assembly 231), the above-mentioned problem occurs, that is, the portion above the bent portion of the first conveyor belt 1162 is suspended, so that the plate is unstable and is easy to overturn.

For this purpose, as shown in fig. 19, a second supporting plate 6218 is fixedly disposed at the top end of the second mounting vertical beam 6214, the second supporting plate 6218 is located at the left side of the washboard 6244, and the distance between the right side surface of the second supporting plate 6218 and the left side surface of the washboard 6244 is in the range of 3-5 mm.

The second supporting plate 6218 is provided with an avoiding notch 62181 for avoiding the second clamping rod 645, the second supporting plate 6218 is provided with a connecting part 62182 extending towards the left side along the horizontal direction, and the connecting part 62182 and the avoiding notch 62181 are arranged at intervals. The free end of the connecting portion 62182 is provided with a guiding inclined surface, and the free end of at least one connecting portion 62182 extends to the horizontal conveying area of the second conveying assembly 231 corresponding to the washboard 6244, that is, the bent portion of the first conveyor belt 1162 of the second conveying assembly 231 corresponding to the washboard 6244 is completely located at the downstream side of the free end of the connecting portion 62182.

As shown in fig. 14, in the actual production line arrangement, the upper side surface of the second supporting plate 6218 is flush with the bearing surface of the first edge bonding machine 31, and when the lifting plate 642 is at the upper limit position, the upper side surface of the first supporting plate 6441 is flush with the upper side surface of the second supporting plate 6218.

The working process of the auxiliary feeding device 6 is as follows:

when the sheet material is transported to the downstream side on the feeding device 2, the second elevation cylinder 643 is in a contracted state, the elevation plate 642 is in a lower limit position at this time, and the roller 66 provided on the first clamp rod 644 is located below the sheet material. The clamp cylinder 65 is in an extended state, i.e., the second carriage 64 is at the leftmost end of the first carriage 62.

The sheet material is fed downstream by the feeder 2 until it abuts against the roller 66 of the positioning arm 62531 and the washboard 6244. Then, the second lifting cylinder 643 operates to drive the lifting plate 642 to ascend, and then the piston rod of the clamping cylinder 65 retracts to drive the two carriages to move towards the right side until the roller 66 on the first clamping rod 644 presses the sheet material, so that the sheet material is clamped and fixed. Then the washboard cylinder 6245 moves to drive the plate to move towards the side close to the first edge bonding machine 31 until the plate abuts against the positioning plate of the first edge bonding machine 31. Then, the fifth driving motor 63 is operated, and the whole clamping and feeding part (i.e. the first carriage 62 and the second carriage 64) is driven by the fifth driving motor 63 to feed the plate members into the first edge bonding machine 31 at the same speed as the first edge bonding machine 31. When the plate is sent to a designated position (generally, the plate is sent to a third pressing wheel of the first edge bonding machine 31, and at this time, the plate can be guaranteed to be pressed by the pressing wheel of the first edge bonding machine 31), the fifth driving motor 63 maintains the conveying speed unchanged, and simultaneously the first retreating cylinder 6254 and the second retreating cylinder 6243 act to respectively drive the second clamping rod 645 and the washboard 6244 to move downwards until the plate is completely moved to the lower side of the plate. At this time, the plate enters the first edge bonding machine 31 for edge bonding. Then, the piston rod of the clamp cylinder 65 is extended, and at the same time, the lift cylinder is retracted, and the fifth driving motor 63 drives the first carriage 62 to move upstream as a whole, and the state is restored to the initial state.

As shown in fig. 23, the first loading transition device 71 includes a third supporting frame 721, and the structure of the third supporting frame 721 is the same as that of the second supporting frame 21, which is not repeated herein.

Further, the sponge suction cup 462 is slidably connected to the picking plate 461, the sponge suction cup 462 can slide up and down relative to the picking plate 461, and a spring 464 for blocking the sponge suction cup 462 from moving upwards is disposed between the sponge suction cup 462 and the picking plate 461.

As a specific implementation manner, in this embodiment, the left and right ends of the picking plate 461 are respectively and fixedly provided with a guide sliding sleeve 4612, a guide rod 463 is disposed in the guide sliding sleeve 4612, the upper end of the guide rod 463 is provided with a limit structure 4631 for preventing the guide rod 463 from slipping out of the guide sliding sleeve 4612, and preferably, the limit structure 4631 is a limit nut. A transverse plate 4632 is fixedly disposed at the lower end of the guide arm 463, and the transverse plate 4632 is fixedly connected to the sponge suction cup 462 via a screw. A spring 464 is sleeved on the guide rod 463 between the transverse plate 4632 and the guide sliding sleeve 4612.

Preferably, two sponge suckers 462 extending in the left-right direction are disposed below the picking plate 461, and the left and right ends of the sponge suckers 462 are respectively fixedly connected to the horizontal plate 4632.

As shown in fig. 25 and 28, a first feeding cylinder 47 is disposed on the swing arm 44, a cylinder body of the first feeding cylinder 47 is fixedly connected to the swing arm 44, and a rod end of a piston rod of the first feeding cylinder 47 is fixedly connected to a pickup plate 461 of the grabbing assembly 46 through a connecting member.

Further, in order to improve the stability when grabbing the plate material, as shown in fig. 25 and 28, two grabbing assemblies 46 are disposed on the swing arm 44, and the two grabbing assemblies 46 are arranged in a line along the length direction of the swing arm 44. The swing arm 44 is provided with a second feeding cylinder 48, and preferably, the first feeding cylinder 47 and the second feeding cylinder 48 are respectively arranged at the front side and the rear side of the swing arm 44. The cylinder bodies of the first feeding cylinder 47 and the second feeding cylinder 48 are respectively and fixedly connected with the swing arm 44, the rod end of the piston rod of the first feeding cylinder 47 is fixedly connected with the picking plate 461 of the grabbing assembly 46 close to one side of the vertical beam 42 through a connecting piece, and the rod end of the piston rod of the second feeding cylinder 48 is fixedly connected with the picking plate 461 of the grabbing assembly 46 close to the suspended end of the swing arm 44 through a connecting piece.

Further, the first feeding cylinder 47 and the second feeding cylinder 48 are oppositely oriented, and when the piston rods of the first feeding cylinder 47 and the second feeding cylinder 48 are retracted, the two sets of gripping assemblies 46 move oppositely. The reason for this is that the length of the oscillating arm 4 can be reduced.

As shown in fig. 2, in the actual production line arrangement, the vertical column 412 near the first edge bonding machine 31 in the direction perpendicular to the sheet material traveling direction is located on the outer side of the second feeding transition device 72, and the vertical beam 42 is located on the side far from the vertical column 412. In this way, it is ensured that the sheet material conveyed from the second feeding transition device 72 has one end located inside the gantry body.

The working process of the rotating plate device is as follows:

(1) the panels are too long and need to be fed downstream, requiring two gripper assemblies 46 to simultaneously grip the panels.

When the board moves to the lower part of the swing arm 44 by the feeding belt conveyor (at this time, the swing arm 44 is perpendicular to the traveling direction of the board, the first feeding cylinder 47 is in an extended state, and the second feeding cylinder 48 is in a retracted state), the seventh driving motor 434 acts to drive the vertical beam 42 to move downward integrally until the sponge suction cup 462 contacts the board. Then the sponge suction cup 462 acts to fix the plate on the grabbing component 46 in an absorbing manner, so that the plate is grabbed. Then the seventh driving motor 434 is operated again to drive the vertical beam 42 to move upward as a whole, and after the vertical beam is moved to a specified position, the eighth driving motor 451 is operated to drive the swing arm 44 to rotate, so that the end of the plate located inside the gantry body rotates toward the downstream side during rotation until the swing arm 44 is parallel to the plate advancing direction. Then, the piston rod of the second feeding cylinder 48 is extended, and at the same time, the piston rod of the first feeding cylinder 47 is retracted, so that the sheet is further fed to the downstream side by the first feeding cylinder 47 and the second feeding cylinder 48, and most of the sheet is positioned on the first rollgang 81 on the downstream side of the sheet rotating machine. Then the seventh driving motor 434 acts again to drive the vertical beam 42 to move downward integrally until the plate is placed on the first roller conveyor 81, then the sponge suction cup 462 is released, the seventh driving motor 434 drives the vertical beam 42 to move upward, and the eighth driving motor 451 drives the swing arm 44 to rotate to a position perpendicular to the plate advancing direction.

Since the motions of the first feeding cylinder 47 and the second feeding cylinder 48 may not be completely synchronized during the feeding process by the first feeding cylinder 47 and the second feeding cylinder 48, the sponge on the sponge suction cup 462 may be torn. In order to solve the problem, as shown in fig. 28, a pulling rod 49 is disposed between two picking plates 461, one end of the pulling rod 49 is fixedly connected to the picking plate 461 of one grabbing assembly, the other end of the pulling rod 49 is slidably connected to the picking plate 461 of the other grabbing assembly through a linear bearing, and a limit stop for preventing the pulling rod 49 from slipping out of the linear bearing is disposed on the end of the pulling rod 49.

(2) The length of the sheet material is small and only one gripper assembly 46 is required to grip the sheet material when it is not necessary to feed the sheet material downstream.

When the plate moves to the position below the swing arm 44 through the feeding belt conveyor (at this time, the swing arm 44 is perpendicular to the advancing direction of the plate, the first feeding cylinder 47 is in a retracted state, and the second feeding cylinder 48 is in an extended state), then the first feeding cylinder 48 acts, and the position of the grabbing assembly 46 at the suspended end of the swing arm 44 is adjusted according to the length of the plate. The seventh drive motor 434 is then actuated to move the vertical beam 42 in its entirety downward until the sponge suction cup 462 of the gripper assembly 46 near the free end of the swing arm 44 contacts the sheet material. Then the sponge suction cup 462 acts to suck and fix the plate on the grabbing component 46, so as to grab the plate. Then the seventh driving motor 434 is operated again to drive the vertical beam 42 to move upward as a whole, and after the vertical beam is moved to a specified position, the eighth driving motor 451 is operated to drive the swing arm 44 to rotate, so that the end of the plate located inside the gantry body rotates toward the downstream side during rotation until the swing arm 44 is parallel to the plate advancing direction. Then, the seventh driving motor 434 acts again to drive the vertical beam 42 to move downward integrally until the plate is placed on the first rollgang 81, then the sponge suction cup 462 is released, the seventh driving motor 434 drives the vertical beam 42 to move upward, and the eighth driving motor 451 drives the swing arm 44 to rotate to a position perpendicular to the plate moving direction.

The first rollgang 81, the second rollgang 82, the third rollgang 83, the fourth rollgang 84 and the fifth rollgang 85 are all roller rollgangs in the prior art, and are not described herein again.

The third conveying and transferring device 13 has the same structure as the first conveying and transferring device 11, and is not described in detail herein.

The first oblique roller conveying device 51 may be an oblique roller conveying device in the prior art, and is not described herein again.

As shown in fig. 1, the first rotary feed channel sequentially includes a third roller conveyor 83, a 90 ° bending machine 91, a fourth roller conveyor 84, a 90 ° bending machine 91, and a second oblique roller conveyor 52 along the flowing direction of the plate.

As shown in fig. 1, the second rotary material conveying channel sequentially comprises a 180 ° bending machine 92, a fifth material conveying roller 85 and a fifth material conveying device 15 along the flowing direction of the sheet material. Here, the fifth transfer device 15 may be an existing transfer device, or may be a transfer device having the same structure as the first transfer device 11. As a specific embodiment, the fifth conveying transmission device 15 in the embodiment adopts a conveying transmission device in the prior art, namely, a power unit is positioned in a sequential conveying transmission device (i.e., a translation roller machine).

Further, as shown in fig. 3, a third feeding transition device 73 is disposed between the third conveying and transferring device 13 and the fifth conveying and transferring device 15, and the structure of the third feeding transition device 73 is the same as that of the first feeding transition device 71. Two ends of the third conveying assembly 722 of the third feeding transition device 73 are respectively connected with the transverse conveying assembly of the third conveying and transferring device 13 and the transverse conveying assembly of the fifth conveying and transferring device 15 in a hand-making type staggered manner, so that the plates can be directly moved from the fifth conveying and transferring device 15 to the third feeding transition device 73 and then moved from the third feeding transition device 73 to the third conveying and transferring device 13, and the plate connection is completed.

The whole production line has the following working procedures: the plate is transversely placed on the first conveying and conveying device 11 and moved to the feeding device 2, and then the plate on the feeding device 2 enters the first edge sealing machine 31 through the auxiliary feeding device 6 to be subjected to edge sealing of the narrow edge on one side. After the edge sealing of the narrow edge on one side is completed, the sheet material enters the first feeding transition device 71 and is moved to the second conveying and transferring device 12 by the first feeding transition device 71. Then the transverse conveying component on the second conveying and transferring device 12 descends to enable the plate to fall onto the longitudinal conveying component of the second conveying and transferring device 12, enter the first rotary conveying and feeding channel through the longitudinal conveying component, return to the first conveying and transferring device 11 through the first rotary conveying and feeding channel, and enable the other side narrow edge without edge sealing to face the first edge sealing machine 31. The above process is then repeated until the sheet material is again moved onto the second transfer conveyor 12. At this time, the transverse conveying component of the second conveying and conveying device 12 is not retracted and is in a jacking state, the plate continues to move to the downstream side until the plate moves below the rotating arm of the plate rotating machine, then the plate rotates by 90 degrees through the plate rotating machine and enters a conveying roller way on the downstream side of the plate rotating machine, and then the plate sequentially passes through the third conveying and conveying device 13 and the first oblique roller conveying device 51 and enters the second edge sealing machine 32 to seal the long edge on one side. After the edge sealing is finished, the plate sequentially enters the second rotary conveying channel through the conveying roller way and the fourth conveying and transferring device 14 (at this time, a transverse conveying component of the fourth conveying and transferring device 14 is in a retraction state, the plate is in contact with the longitudinal conveying component), and enters the third conveying and transferring device 13 again after rotating for 180 degrees through the second rotary conveying channel, and the long edge of the other side, which is not subjected to edge sealing, faces the second edge sealing machine 32. The process is then repeated until the sheet material is again moved onto the fourth transfer conveyor 14, completing the four edge banding operation.
