DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-9The present invention provides a technical solution, a carpet stacker with continuous lifting and feeding, wherein the lifting and loading component 1 is used to lift the flat carpet and then transport it forward, and the conveying and storage component 2 includes a frame 21 arranged at the front side of the lifting and loading component 1, a conveying line 22 fixed to the inner cavity of the frame 21 near the top position, a clamping conveying mechanism 24 which is slidably mounted on both sides of the middle of the top of the frame 21 and is used to clamp the edges of the carpet on both sides and transport it forward, a screw driving member 23 which drives the clamping conveying mechanisms 24 on both sides to slide in the opposite direction synchronously, and a conveying line 22 arranged at the front end of the top of the frame 21. The material blocking mechanism 25 and the material removing mechanism 26 are arranged at the middle part of the top of the frame 21 and are used to press the carpet downwards. The material picking conveying assembly 3 is arranged at the front side of the conveying line 22 and is used to convey the carpet forward. The pallet conveying assembly 4 includes a lifting conveying line 43 which is arranged at the front side of the material picking conveying assembly 3 and can be vertically translated, a pallet feeding conveying line 41 which is arranged at the lower front side of the lifting conveying line 43, and a pallet discharging conveying line 42 which is arranged above the pallet feeding conveying line 41. The grabbing robot 5 includes a clamping claw mechanism 55 which moves back and forth in the longitudinal direction above the middle part of the material picking conveying assembly 3 and the lifting conveying line 43.

[0035] In summary, after the lifting and loading assembly 1 lifts the carpet to the same height as the edge clamping and conveying mechanism 24 , the carpet is conveyed toward the edge clamping and conveying mechanism 24 .

[0036] According to the width of the carpet to be stacked, the screw drive member 1 23 drives the edge clamping conveying mechanisms 24 on both sides to slide synchronously toward or away from each other along the top end of the frame 21 to ensure that the edge clamping conveying mechanisms 24 can clamp the edges of the carpet on both sides, that is, the edges of the carpet on both sides are conveyed forward in a clamped state, so that the front end of the carpet moves to the material blocking mechanism 25, and then the stripping mechanism 26 presses the carpet downward, so that the carpet is detached from the edge clamping conveying mechanism 24 and falls on the conveyor line 2 22; and so on, multiple carpets can be stacked on the conveyor line 2 22 in this way, so as to realize the stacking process of multiple layers of carpets at one time.

[0037] The material blocking mechanism 25 is raised, and the conveyor line 22 conveys the carpet forward to the material taking and conveying assembly 3 .

[0038] The clamp mechanism 55 moves to the top of the carpet, grabs the carpet, and then moves forward.

[0039] The empty pallet is first placed on the pallet feeding conveyor line 41, and then the pallet feeding conveyor line 41 transports the pallet backward to the lifting conveyor line 43. The lifting conveyor line 43 carries the empty pallet upward to a height flush with the pallet discharging conveyor line 42, and then transports the empty pallet to the rear end of the pallet discharging conveyor line 42.

[0040] The clamping mechanism 55 stacks the carpets in the empty pallet to complete the carpet stacking process, and the pallet discharge conveyor line 42 conveys the pallet carrying the carpets forward to the next station.

[0041] See also Figure 3 The edge clamping conveying mechanism 24 includes a longitudinal beam 241 which is slidably mounted on both sides of the middle part of the top of the frame 21 and extends longitudinally respectively, a plurality of vertical plates 242 whose tops are fixed to the longitudinal beam 241, a narrow conveyor belt 243 whose frame is fixed to the bottom end of the inner wall of the vertical plate 242 and extends longitudinally, a clamping telescopic cylinder 244 whose piston cylinder is fixed to the top of the inner wall of the vertical plate 242 and extends vertically, and a pressure roller 245 installed at the bottom end of the piston rod of the clamping telescopic cylinder 244. The screw drive member 1 23 is used to drive the longitudinal beams 241 on both sides to slide in the opposite direction synchronously. That is, when the conveying line 1 12 conveys the carpet forward, the two side edges of the front end of the carpet are first conveyed to the rear end of the belt surface of the narrow conveyor belt 243. At this time, the clamping telescopic cylinder 244 at the rear end presses the pressure roller 245 on the edge of the carpet, and the narrow conveyor belt 243 conveys the carpet forward, so that the edges of both sides of the carpet are conveyed forward in a clamped state.

[0042] The stripping mechanism 26 comprises a fixed plate 261 fixed at the top center of the frame 21, a stripping telescopic cylinder 262 whose piston cylinder is vertically fixed to both sides of the middle of the top surface of the fixed plate 261 and whose piston rod passes through the fixed plate 261, and a pressing plate 263 fixed to the bottom end of the piston rod of the stripping telescopic cylinder 262. During the stripping operation, the stripping telescopic cylinder 262 presses the pressing plate 263 downward, and then cooperates with the action of the clamping telescopic cylinder 244 to lift the pressure roller 245, so that the edges of the carpet on both sides are separated from the narrow conveyor belt 243, and the carpet falls on the conveyor line 22.

[0043] The material blocking mechanism 25 comprises a top plate 251 fixed to the middle of the front end of the fixed plate 261, a material blocking telescopic cylinder 252 whose piston cylinder is vertically fixed to the center of the top surface of the top plate 251 and whose piston rod passes through the top plate 251, and a material blocking frame 253 fixed to the bottom end of the piston rod of the material blocking telescopic cylinder 252. That is, when it is necessary to block the material, the material blocking telescopic cylinder 252 pushes the material blocking frame 253 downward, so that the material blocking frame 253 is horizontal on the upper side of the front end of the conveying line 2 22; when it is necessary to continue to convey the carpet forward, the material blocking telescopic cylinder 252 only needs to lift the material blocking frame 253.

[0044] See also Figure 2 The lifting and loading assembly 1 includes a frame 11, a conveying line 12 that moves up and down along the inner cavity of the frame 11, and a lifting drive 13 for driving the conveying line 12 to move up and down. That is, the lifting drive 13 drives the conveying line 12 to slide vertically in the frame 11 to achieve the lifting and loading of the carpet. The lifting drive 13 can be a telescopic cylinder, a screw lifting mechanism, or a rope or chain lifting method.

[0045] See also Figure 4 The material taking and conveying assembly 3 comprises a base frame 31 fixed on the ground at the front side of the frame 21, a conveying line 32 whose frame is fixed to the middle of the base frame 31 and extends in the longitudinal direction, side beams 33 which are laterally slidably mounted on both ends of the top surface of the base frame 31 and extend in the longitudinal direction, clamping plates 34 fixed to the inner side walls of the side beams 33, and a screw driving member 235 for driving the two side beams 33 to slide in the opposite direction synchronously. That is, the screw driving member 25 can adjust the distance between the clamping plates 34 on both sides through the side beams 33, so that the conveying line 33 can play a good side blocking role when conveying carpets of different widths, and prevent the carpets from running off when being conveyed on the conveying line 332.

[0046] See also Figure 8 The grabbing manipulator 5 also includes two gantry frames 52 respectively spanning the two sides of the material taking conveying assembly 3 and the tray discharging conveying line 42, a longitudinal double beam 51 whose front and rear ends are respectively fixed to the top of the gantry frames 52 and extending in the longitudinal direction, a screw drive member 556 for driving the longitudinal rods 552 on both sides to slide synchronously in the opposite direction, a longitudinal shifting base 53 sliding forward and backward along the longitudinal double beam 51, and a lifting base 54 moving vertically along the longitudinal shifting base 53, and a clamping claw mechanism 55 connected to the bottom of the lifting base 54. That is, the clamping claw mechanism 55 is reciprocated above the material taking conveying assembly 3 and the tray discharging conveying line 42 by sliding the longitudinal shifting base 53 along the longitudinal double beam 51; and the vertical movement of the clamping claw mechanism 55 is realized by the vertical movement of the lifting base 54, so as to complete the material grabbing and placing process.

[0047] See also Fig. 9 The clamp mechanism 55 includes a connecting frame 551 fixed to the bottom surface of the lifting base 54, longitudinal rods 552 that slide laterally along the two ends of the connecting frame 551 and extend longitudinally respectively, a plurality of L-shaped plates 553 whose top ends are fixed to the inner side of the longitudinal rods 552, a pressing and telescopic cylinder 554 whose piston cylinder is fixed to the top of the inner side wall of the L-shaped plate 553, and a pressing plate 555 that is fixed to the bottom end of the piston rod of the pressing and telescopic cylinder 554 and is parallel to the inner folding plate at the bottom end of the L-shaped plate 553. That is, when grabbing the carpet, the screw driving member 556 drives the longitudinal rods 552 on both sides to move laterally according to the width of the carpet, so that the bottom folding plate of the L-shaped plate 553 and the pressing plate 555 are respectively located at the lower side and the upper side of the two side edges of the carpet, and the pressing and telescopic cylinder 554 contracts, so that the two side edges of the carpet can be clamped between the pressing plate 555 and the bottom folding plate of the L-shaped plate 553. When unloading, the pressing and telescopic cylinder 554 lifts the pressing plate 555, and then the screw driving member 556 drives the longitudinal rods 552 on both sides to move to both sides to release the clamping and fixing of the edge of the carpet.

[0048] See also Figure 5The pallet conveying assembly 4 further includes a vertical frame 44 fixed on the ground in front of the material taking conveying assembly 3, and a lifting conveying line 43 is vertically slidably mounted in the inner cavity of the vertical frame 44. A lifting telescopic cylinder 45 extending vertically and used to drive the lifting conveying line 43 to slide vertically is provided on the ground outside the vertical frame 44. That is, the lifting telescopic cylinder 45 drives the lifting telescopic line 43 to slide up and down along the inner cavity of the vertical frame 44 to realize the lifting and dropping process of the empty pallet.

[0049] See also Figure 6-7 The pallet conveying assembly 4 also includes a side guard mechanism 46 and a centering mechanism 47. The side guard mechanism 46 includes a lower frame 461 fixed laterally to the lower middle of the lifting conveying line 43, a side guard telescopic cylinder 462 fixed laterally to the middle of both sides of the lower frame 461, and a baffle 463 fixed to the end of the piston rod of the side guard telescopic cylinder 462. The centering mechanism 47 includes a cantilever frame 471 whose bottom end is laterally slidably clamped on both sides of the bottom frame of the rear end of the pallet discharge conveying line 42, a screw drive member 473 for driving the cantilever frames 471 on both sides to synchronously slide in the opposite direction, and a centering plate 472 fixed to the inner end of the top of the cantilever frame 471. That is, the side guard telescopic cylinder 462 pushes the baffle 463 toward the middle to limit the conveying of the empty pallet on both sides to prevent the empty pallet from running off during the conveying process. The screw drive member 473 drives the cantilever frame 471 to move synchronously toward the center so as to center the empty pallet on the stacking station at the rear end of the pallet discharge conveyor line 42, so that the clamping mechanism 55 can accurately stack the carpet on the empty pallet.
