Description

Technical Field

[0001] The present invention relates to the technical field of fireproof cloth storage, and in particular to a continuous conveying and stacking device based on cut fireproof cloth. Background Art

[0002] During the production process, fireproof cloth usually rolls off the production line in the form of wide widths and long lengths. In order to meet the specific size requirements of different application scenarios, it must be precisely cut. After cutting, single sheets or small batches of fireproof cloth need to be neatly and stably stacked into stacks. The purpose of stacking is to facilitate subsequent counting, packaging, storage and transportation management. After stacking, these cloth stacks usually need to be efficiently and non-destructively transferred to a high-bay warehouse for automated storage, so that they can be scheduled, managed and subsequently distributed or further processed according to order requirements.

[0003] However, the current common stacking method has certain shortcomings: although manual stacking is highly flexible, it is inefficient, labor-intensive, difficult to ensure stacking accuracy, and there are safety hazards; and the use of robots for automated handling and stacking, although it has improved efficiency and positioning accuracy, the fireproof cloth itself has a certain flexibility. During the process of grabbing and placing, it is difficult for the robot to completely eliminate the gaps and trapped air between single layers of cloth, resulting in local bulges or uneven undulations between the stacked cloth layers. This non-compacted state will significantly reduce the overall stability of the cloth stack as the stacking height increases, and there is a risk of tilting or even tipping over. At the same time, the uneven stacking state can easily cause difficult-to-eliminate wrinkles in the fireproof cloth during subsequent storage or handling, seriously affecting the flatness, appearance quality and final performance of the product.

[0034] like Figure 1-Figure 5As shown, in order to flatten and compact the fireproof cloth, a flattening mechanism is provided at the upper end of the stacking rack 1, which is linked to the lifting and lowering of the suction cup handling robot. As a preferred embodiment, the flattening mechanism includes a floating frame 6 vertically movably arranged on the side wall of the upper end of the stacking rack 1, and a first elastic member 15 is provided between the bottom of the floating frame 6 and the side wall of the stacking rack 1.

At the same time, in order to facilitate the subsequent swinging and resetting of the swing arm 18, a first torsion spring 21 is provided between the end of the swing shaft 19 away from the swing arm 18 and the inner wall of the blind hole.

[0035] like Figure 4-Figure 6As shown, in order to prevent the flattening roller 13 from rising and causing back swing, a locking assembly is also included at the end of the floating frame 6. As a preferred embodiment, the locking assembly includes a locking pin 17 that is vertically movably arranged at the end of the floating frame 6 and corresponds to the upper end of the swing arm 18. The locking pin 17 is a polygonal column and will not rotate with the floating frame 6. The longitudinal section of the locking pin 17 is "T"-shaped. A ratchet 23 is provided on the upper end side of the swing arm 18, and a movable groove 24 is provided on the lower end side of the locking pin 17. A pawl 25 corresponding to the ratchet 23 is rotatably provided on the inner side of the movable groove 24. A second torsion spring 26 for resetting the pawl 25 is provided between one end of the pawl 25 and the inner wall of the movable groove 24.

Specifically, the pawl 25 is tilted downward in the initial state, and at this time the upper end of the pawl 25 is in contact with the inner top wall of the movable groove 24, and there is a gap between the lower end of the pawl 25 and the inner bottom wall of the movable groove 24, so that the upper end of the pawl 25 can be flipped downward when pressure is applied, and the ratchet 23 is tilted upward, and the ratchet 23 is used to engage with the bottom of the pawl 25, so that the locking pin 17 and the floating frame 6 can be moved downward in the future, and the end of the suction cup frame 4 corresponds to the locking pin 17, and the end of the suction cup frame 4 is used to press down the locking pin 17 and the floating frame 6, and when the locking pin 17 compresses the second elastic member 33, the floating frame 6 moves slightly downward.

[0036] like Figure 1-Figure 3 、 Figure 7-Figure 8As shown, in order to carry the fireproof cloth, a pallet 11 for carrying the fireproof cloth is horizontally arranged in the stacking rack 1. A forklift hole is provided on the pallet 11 to facilitate subsequent forklift transportation to the stereoscopic warehouse. A driving mechanism for driving the vertical displacement of the pallet 11 is provided on the stacking rack 1. As a preferred embodiment, the driving mechanism includes a synchronous shaft 27 rotatably arranged at the upper and lower ends of the inner side wall of the stacking rack 1 through a bearing. The ends of the two synchronous shafts 27 on the same side are jointly provided with a synchronous belt 5. The side walls of the synchronous belt 5 are evenly provided with support blocks 12 for supporting the pallet 11. When the pallet 11 is displaced to the bottom, a subsequent group of support blocks 12 will just reach the initial position. In order to facilitate the subsequent support of the pallet 11 and prevent the pallet 11 from moving, a slot is set on the support block 12, and support feet are set at the four corners of the bottom of the pallet 11, which can be plugged into the slot. A linkage component is provided on the side of the stacking frame 1 for driving the synchronous shaft 27 to rotate and to be linked with the lifting of the floating frame 6. The linkage component can realize the downward movement of the pallet 11 before flattening the fireproof cloth each time, so as to adapt to the flattening mechanism with constant height, and at the same time, it can also realize the fixed stroke of the suction cup handling manipulator. As an embodiment, the linkage component includes a worm gear 29 installed on the synchronous shaft 27, and the upper end side of the stacking frame 1 is rotatably provided with a worm 28 meshing with the worm gear 29. The bottom of the worm 28 is rotatably connected to the one-way rotating shaft 14 through a one-way rotating member. Specifically, the one-way rotating member is a one-way bearing, which is embedded in the bottom of the worm 28. The upper end of the one-way rotating shaft 14 is fixed to the inner wall of the one-way bearing, and the one-way bearing is configured as follows: when the driving sleeve 30 drives the guide block 31 to move downward, the one-way rotating shaft 14 can drive the worm 28 to rotate, and then the worm 28 can drive the synchronous shaft 27 to rotate through the worm gear 29, and the synchronous shaft 27 can drive the synchronous belt 5 to operate, and the synchronous belt 5 can drive the support block 12 to move longitudinally. The upper end side wall of the one-way rotating shaft 14 is provided with a spiral guide groove 32, and the lower end side wall of the one-way rotating shaft 14 is provided with a vertical groove connected to the spiral guide groove 32 20. A drive sleeve 30 is installed through the side of the floating frame 6, and the drive sleeve 30 is movably sleeved on the outside of the one-way rotating shaft 14. The inner wall of the drive sleeve 30 is provided with a guide block 31 that cooperates with the spiral guide groove 32 and the vertical groove 20 for movable guidance. The inner wall of the spiral guide groove 32 and the inner wall of the vertical groove 20 are smoothly transitioned. The guide block 31 is hemispherical, and the spiral guide groove 32 and the guide block 31 are configured as follows: when the guide block 31 moves from the upper end of the spiral guide groove 32 to the bottom of the spiral guide groove 32, the longitudinal displacement distance of the support block 12 is the thickness of a fireproof cloth, and the self-locking mechanism of the worm wheel 29 and the worm 28 can be used to increase the stability of the synchronous shaft 27, thereby avoiding the worm 28 from rotating on its own.

[0037] Working principle: When in use, the tray 11 is placed on top of multiple support blocks 12 at the same height inside the stacking rack 1, and the cut fireproof cloth is transported from the conveying device 2 to the direction of the stacking rack 1. When it is transported to the right place, the first driving source 7 drives the screw rod 10 to rotate, and the screw rod 10 drives the transfer rack 8 to move, and the transfer rack 8 drives the suction cup rack 4 to move above one end of the conveying device 2, and then the second driving source 9 drives the suction to move downward, and the suction cup rack 4 realizes the adsorption and rise of the fireproof cloth through the suction cup, and then transfers the fireproof cloth to the top of the stacking rack 1, and the second driving source 9 drives the suction cup rack 4 to move downward again. The end of the suction cup rack 4 will first contact the upper end of the locking pin 17. As the suction cup rack 4 moves downward, the locking pin 17 is first When the suction cup frame 4 is pressed down, the second elastic member 33 contracts. At this time, the floating frame 6 moves down slightly and remains roughly stationary. When the locking pin 17 drops to the limit distance, the pawl 25 corresponds to the ratchet 23. Then, as the suction cup frame 4 moves down, the floating frame 6 begins to move down. At this time, the first elastic member 15 contracts and the guide column 16 guides. As the floating frame 6 moves down, the entire structure including the swing arm 18 and the flattening roller 13 is driven to move down. Then the flattening roller 13 will contact the top of the tray 11. Under the action of pressure, the flattening roller 13 drives the swing arm 18 to swing outward. At this time, since there is no fireproof cloth on the top of the tray 11, the flattening roller 13 only contacts the top of the tray 11 at the beginning and does not play a role. Flattening effect, due to the swing of the swing arm 18, the first torsion spring 21 twists and stores force, and the ratchet 23 presses down the pawl 25 when passing through the pawl 25, and then the second torsion spring 26 twists, and when the ratchet 23 reaches the bottom of the pawl 25, the pawl 25 resets, and then the ratchet 23 and the bottom of the pawl 25 are engaged and limited, and then the suction cup frame 4 drives the fireproof cloth to the set height, so the suction cup lowers the fireproof cloth to the top of the tray 11, and then the suction cup frame 4 rises and resets, and the first elastic member 15 drives the floating frame 6 to rise and reset first. Since the second elastic member 33 has not reset, the swing arm 18 is still locked at this time and will not swing back to contact the fireproof cloth. As the floating frame 6 is completely reset, the flattening roller 13 rises and resets The suction cup frame 4 is at its initial height and is above the fireproof cloth. Subsequently, as the suction cup frame 4 rises, the suction cup frame 4 and the floating frame 6 begin to separate, and the second elastic member 33 gradually drives the locking pin 17 to reset, and then the pawl 25 rises, and the ratchet 23 is unlocked. Under the action of the deadweight of the flattening roller 13 and the reset force of the first torsion spring 21, the swing arm 18 drives the flattening roller 13 to swing back and reset. At this time, the flattening roller 13 is above the fireproof cloth and there is a gap between it and the fireproof cloth. Then, the above steps are repeated to carry the fireproof cloth. Subsequently, due to the presence of the fireproof cloth on the pallet 11, the subsequent flattening roller 13 will flatten the fireproof cloth under pressure, squeeze out the air in the gap of the fireproof cloth, and avoid wrinkles.

[0038] In addition, since the height of the flattening roller 13 remains unchanged, the height of the pallet 11 needs to be continuously adjusted as the fireproof cloth is stacked. Specifically, when the floating frame 6 is driven downward by the suction cup frame 4, the driving sleeve 30 is driven downward synchronously by the floating frame 6. Before the flattening roller 13 contacts the fireproof cloth, the one-way rotating shaft 14 drives the worm 28 to rotate slightly through the one-way bearing under the cooperation of the guide block 31 and the spiral guide groove 32, and then the worm gear 29 drives the synchronous shaft 27 to rotate, and the synchronous shaft 27 drives the synchronous belt 5 to operate slightly, and then the support block 12 drives the pallet 11 to drop slightly by about the thickness of the fireproof cloth. When the flattening roller 13 begins to contact and flatten the fireproof cloth, the guide The block 31 enters the vertical groove 20. At this time, the synchronous belt 5 does not run. After the fireproof cloth is flattened and put down, even if the guide block 31 enters the spiral guide groove 32 again, it will not drive the worm 28 to rotate. At this time, under the action of the one-way bearing, the one-way rotating shaft 14 will rotate relative to the worm 28. The one-way rotating shaft 14 does not play a driving role during the rising and resetting stage of the floating frame 6. In this cycle, the synchronous belt 5 always moves in one direction, thereby realizing the gradual downward movement of the stacked fireproof cloth. Finally, the pallet 11 can be transported to the stereoscopic warehouse for storage by a forklift, and then the pallet 11 is continued to be fixed on the upper support block 12 to start a new round of fireproof cloth stacking operation.
