Description

Technical Field

[0001] The invention relates to the field of plate production, and in particular to a light and thin plate stacking and transporting device. Background Art

[0002] In sheet production, stacking and handling of sheets is a key link in achieving efficient storage, transportation and subsequent processing. By stacking the sheets longitudinally into stacks in a specific order, it can greatly save site space and improve work efficiency. It is also convenient for batch management and automated circulation. The stability, precision and safety of sheet stacking directly affect the production rhythm and product quality. Therefore, it is necessary to rely on specialized handling devices to achieve precise positioning and damage-free operation.

[0003] The current mainstream plate stacking and handling devices mostly use suction cup robots to grab incoming plates and stack them in the target area, but they have significant limitations. First, as the stacking height increases, the cumulative thickness of the plates changes, and the system control logic needs to be frequently adjusted to adapt to the discharge height. The operation is complicated and has low fault tolerance. Moreover, the direct contact and friction between the plates during the stacking process can easily lead to surface wear or compressive deformation, especially for the plates at the bottom. The damage to thin plates is particularly prominent.

[0004] Secondly, there are safety hazards in the handling method that relies entirely on vacuum adsorption. If dust, oil or processing debris adheres to the surface of the plate, the sealing of the suction cup will decrease, which can easily lead to adsorption failure and cause the plate to slip. In addition, when the power supply of the equipment is abnormal or the vacuum system fails, the suction cup will lose pressure instantly, which may cause the entire stack of plates to collapse, endangering the safety of personnel and equipment. The reliability of the system needs to be improved urgently.

It should be noted that when the plate is adsorbed, the driving arm 27 corresponds to the gap between adjacent rollers of the roller conveyor.

[0025] like Figure 4-Figure 6 , Fig.12As shown, in order to prevent the synchronous belt 4 from running when the second gear 41 is not meshed with the first driving gear 15, a groove is provided on the inner wall of the upper end of the driving groove 7, and a floating frame 13 is vertically movably provided inside the groove through a guide rod.

When the driving arm 27 moves down to the limit distance, the latch tooth 24 can be plugged into the gear tooth gap on the locking gear 14 again.

[0026] Further, such as Figure 8-Figure 12As shown, secondary protection components are symmetrically arranged at both ends of the suction cup frame 25, and the secondary protection components include a rotating shaft 36 rotatably arranged at both ends of the suction cup frame 25, and an anti-drop claw 26 is arranged on the rotating shaft 36. One end of the anti-drop claw 26 can be flipped to the bottom of the suction cup frame 25 following the rotating shaft 36, and the end of the rotating shaft 36 is connected to the second driving gear 33 through a one-way bearing for unidirectional rotation. Specifically, a one-way bearing is fixed to the end of the rotating shaft 36, and the outer wall of the one-way bearing is fixed with the second driving gear 33, thereby realizing unidirectional rotation. The driving arm 27 corresponds to the end of the rotating shaft 36, and the upper end of one side of the driving arm 27 is evenly provided with first gear teeth 40 corresponding to the second driving gear 33. In order to achieve locking, a ratchet 35 is fixed at one end of the rotating shaft 36, and the upper end of the suction cup frame 25 is rotatably provided with a ratchet 35. 5 corresponding to the pawl 34, in order to automatically unlock and lock, a damping lifting shaft 31 corresponding to the pawl 34 is movably arranged on the suction cup frame 25, and a rubber ring is arranged on the outer wall of the damping lifting shaft 31, and the rubber ring is in close contact with the inner wall of the penetration of the suction cup frame 25, so that the damping lifting shaft 31 will not be easily displaced, and a lifting arm 37 extending to the bottom of the pawl 34 is arranged on one side of the upper end of the damping lifting shaft 31, and the lifting arm 37 is used to drive the pawl 34 to flip, and a lower pressure plate 29 corresponding to the damping lifting shaft 31 and used to drive the damping lifting shaft 31 to descend is arranged on the side wall of the lifting frame 28, and in order to facilitate the reset and flipping of the rotating shaft 36 and the anti-drop claw 26, torsion springs 38 are arranged on the outer sides of both ends of the rotating shaft 36, and one end of the torsion spring 38 is fixed to the outer wall of the rotating shaft 36, and the other end is fixed to the inner wall of the suction cup frame 25.

[0027] like Figure 3 As shown, in order to prevent the plate from escaping from the inner side of the stacking frame 3, a limiting baffle 12 for limiting the position of the plate is movably inserted into the inner wall at both ends of the stacking frame 3.

[0028] When in use, insert the empty stacking rack 3 into the positioning groove at one end of the transport rack 2, lock it with bolts to prevent movement, ensure that the driving arm 27 can correspond to the driving groove 7, and the plate conveying device 1 transports the plate to one side of the transport rack 2, and then control the second driving source 11 to drive the screw rod 8 to rotate, the screw rod 8 drives the transverse frame 9 to move transversely, and the suction cup frame 25 moves to the top of the plate. Initially, the lower end of the damping lifting shaft 31 is lower than the bottom of the suction cup 30, the anti-drop claw 26 is in an open state, and the pawl 34 is in a locked state with the ratchet wheel 35. Then the first driving source 10 drives the lifting frame 28 and the suction cup frame 25 to move downward as a whole, and the bottom of the damping lifting shaft 31 first contacts the top of the plate, and as the suction cup frame 25 moves downward, the damping lifting shaft 31 is pushed up, and the damping lifting shaft 31 is pushed upward through the lifting arm 37 The movable pawl 34 flips over, and then the pawl 34 is separated from the ratchet wheel 35. Under the restoring force of the torsion spring 38 and the deadweight of the anti-drop pawl 26, the rotating shaft 36 drives the anti-drop pawl 26 to flip downward, and can be flipped to the bottom edge of the plate through the gap between the adjacent rollers on the plate conveying device 1. Even if it is blocked by the rollers on the plate conveying device 1, it can be flipped to the bottom edge of the plate after the suction cup 30 absorbs the plate and moves up. A rubber ring is provided on the damping lifting shaft 31 to closely contact the penetration point of the suction cup frame 25, and the damping lifting shaft 31 will not be easily lifted or lowered. In addition, during the period when the suction cup 30 absorbs the plate, the third elastic member 32 between the suction cup frame 25 and the lifting frame 28 contracts slightly, and the lower pressure plate 29 will not contact the upper end of the damping lifting shaft 31. In addition, due to the elastic effect of the third elastic member 32, it can To avoid damage to the plate and to achieve a buffering effect, the plate is transported to the top of the stacking rack 3 after being adsorbed, and the first driving source 10 drives the suction cup rack 25 and the lifting rack 28 to move downward as a whole again. As the plate moves downward, the lower end of the driving arm 27 enters the driving groove 7, and the first guide wheel 20 enters the third guide groove 43. Then, under the action of the inclined surface in the third guide groove 43, the first guide wheel 20 pushes the driving rack 19 to move horizontally. Under the action of the first guide groove 22 and the second guide wheel 21, the traction plate 18 drives the floating rack 13 to rise, and the first elastic member 17 contracts, so that the floating rack 13 drives the latching tooth 24 to separate from the locking gear 14, and then the second gear tooth 41 engages with the first driving gear 15. As the driving arm 27 moves downward, the first guide wheel 20 enters the upper end of the third guide groove 43 , the second gear teeth 41 drives the synchronous shaft 16 to rotate through the first driving gear 15, the synchronous shaft 16 drives the synchronous belt 4 to operate, and the synchronous belt 4 drives the limit shaft 5 to follow the operation. As the suction cup frame 25 moves downward, the lap arm 39 on the side of the suction cup frame 25 will overlap the upper edge of the stacking frame 3, and the suction cup frame 25 is restricted from moving downward. At this time, the lifting frame 28 continues to move downward, the third elastic member 32 contracts, and the lifting frame 28 and the suction cup frame 25 are relatively displaced. Then the first gear teeth 40 on the driving arm 27 are engaged with the second driving gear 33, and then the second driving gear 33 drives the rotating shaft 36 to flip, and the rotating shaft 36 drives the anti-drop claw 26 to move away from the bottom of the plate, and the torsion spring 38 is twisted. During this period, the synchronous belts 4 on both sides drive a corresponding set of limit shafts 5 to flip from the upper end to the inner side of the stacking frame 3.Then the first guide wheel 20 reaches the upper end of the third guide groove 43 and falls into the upper end of the second guide groove 42, the first elastic member 17 is reset, the floating frame 13 descends, the latching tooth 24 is plugged into the gear gap on the locking gear 14, and then the synchronous shaft 16 is locked, and then the lifting frame 28 continues to move down for a distance, the lower pressure plate 29 begins to contact and press down with the upper end of the damping lifting shaft 31, and then the suction cup 30 puts down the plate, and under the action of the plate's own weight and the downward thrust of the damping lifting shaft 31, the plate can quickly fall to the upper end of the limit shaft 5, at this time, the lower end of the damping lifting shaft 31 protrudes from the bottom of the suction cup 30 again, and due to the downward movement of the damping lifting shaft 31, the lifting arm 37 moves down synchronously, the pawl 34 is reset under its own weight, and the pawl 34 locks the flipped ratchet 35, and then the first driving source 10 drives the lifting frame 28 and the suction cup frame 25 to rise and reset as a whole, and continue to carry subsequent plates; It should be noted that when the lifting frame 28 drives the driving arm 27 to rise, since the second driving gear 33 rotates unidirectionally on the rotating shaft 36 through the one-way bearing, the first gear tooth 40 is engaged with the second driving gear 33 and will not drive the rotating shaft 36 to rotate. At this time, the second driving gear 33 and the rotating shaft 36 rotate relative to each other. Similarly, the second gear tooth 41 rises and engages with the first driving gear 15 and will not drive the synchronous shaft 16 to rotate. The first driving gear 15 and the synchronous shaft 16 rotate relative to each other. Moreover, when the driving arm 27 rises, the first guide wheel 20 will enter the lower end of the second guide groove 42 under the guidance of the upper end inclined surface of the second guide groove 42. At this time, the first guide wheel 20 drives the traction plate 18 to move horizontally through the driving frame 19, and the second elastic member 23 is compressed. Before stacking, the limit baffle 12 can be pulled out to limit the plate to prevent the plate from detaching from the stacking frame 3. The stacking frame 3 can be transported by a forklift or manually.

[0029] The technical scope of the present invention is not limited to the contents in the above description.
