Description

Technical Field

[0001] The utility model relates to the technical field of depalletizers, in particular to an automatic depalletizer. Background Art

[0002] On the filling production line, in order to prevent bottles from scratching the bottle walls and generating noise due to friction and collision between each other, and also to save manpower and improve production efficiency, a depalletizer is used to depalletize the stacked empty bottles in layers onto the bottle conveyor, which then transports the empty bottles to the filling station for filling. The existing depalletizer generally includes a gantry, a material transfer mechanism longitudinally movably arranged on the gantry, and a bottle conveying platform arranged on one side of the gantry. The material transfer mechanism includes a material transfer frame that is horizontally movable, a clamp arranged on the material transfer frame, and a transition plate arranged below the material transfer frame. During depalletizing, the material transfer frame moves to the side of the material stack through longitudinal and horizontal movements, and the transition plate moves to one side of the material stack through longitudinal movement. After the clamp clamps and fixes a single layer of bottles in the material stack, the bottle is transferred to the transition plate through horizontal movement of the material transfer frame. Then, the transition plate and the material transfer frame move longitudinally to one side of the bottle conveying platform. The material transfer frame drags the bottles on the transition plate to the bottle conveying platform to complete the bottle depalletizing operation. However, in the above structure, since there is a certain gap between the transition plate and the material stack and the bottle conveying platform, when the material transfer frame pushes the bottles to or away from the transition plate, bottles with smaller outer diameters may fall through the gap between the transition plate and the material stack or the bottle conveying platform, which is not conducive to the orderly progress of the depalletizing operation and affects the efficiency of the depalletizing operation.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] As shown in the figure, an automatic depalletizer includes a gantry 1, a material moving mechanism 2, a bottle conveying platform 3 and a feeding mechanism 5. The material moving mechanism 2 includes a lifting frame 21, a transition plate 22 and a material moving frame 23.

[0029] Specifically, the lifting frame 21 is slidably arranged on the gantry 1 and is transmission-connected to the first driving source: the lifting frame 21 is slidably arranged on the gantry 1 through a linear guide rail, the first driving source is a first motor 11, and the gantry 1 is rotatably provided with a first transmission screw 12 transmission-connected to the first motor 11, and the first transmission screw 12 is screwed with a first transmission seat 13, and the lifting frame 21 is fixedly connected to the first transmission seat 13. Through the above structure, the first motor 11 drives the first transmission screw 12 to rotate, and the first transmission screw 12 drives the first transmission seat 13 to slide longitudinally on the gantry 1 by screwing with the first transmission seat 13, thereby driving the lifting frame 21 to slide longitudinally on the gantry 1.

The first gear 212 cooperates with the first rack 251 to drive the telescopic plate 25 to slide horizontally on the lifting frame 21. As the telescopic plate 25 slides, the second gear 252 cooperates with the second rack 213 to rotate. The second gear 252 cooperates with the third rack 233 to drive the material moving frame 23 to slide horizontally on the telescopic plate 25, thereby achieving multi-stage telescopic sliding of the material moving frame 23 on the lifting frame 21.

[0032] Specifically, the bottle conveying platform 3 is provided with a first bottle conveying mesh belt 31 and a second bottle conveying mesh belt 32 connected head to tail, the second bottle conveying mesh belt 32 is transmission connected to the third motor 33 provided on the bottle conveying platform 3, and the bottle conveying platform 3 is slidingly provided with a first material shifting cylinder 35 which is respectively located on one side of the first bottle conveying mesh belt 31 and transmission connected to the fourth motor 34 provided on the bottle conveying platform 3 and with the output shaft facing upward; the bottle conveying platform 3 is fixedly provided with a material blocking cylinder 36 which is located on one side of the second bottle conveying mesh belt 32 and with the output shaft facing upward, and the output shafts of the first material shifting cylinder 35 and the material blocking cylinder 36 are respectively fixedly connected with a first material shifting plate 351 and a material blocking plate 361 located above the head ends of the first bottle conveying mesh belt 31 and the second bottle conveying mesh belt 32.

[0033] Specifically, the first material-diverting cylinder 35 is slidably arranged on the bottle conveying platform 3 and is transmission-connected to the fourth motor 34: a second transmission seat 37 is slidably arranged on the bottle conveying platform 3 through a linear guide rail, and a second transmission screw 38 is rotatably arranged on the bottle conveying platform 3 and is screwed on the second transmission seat 37 and transmission-connected to the fourth motor 34.

Through the above structure, the fourth motor 34 drives the second transmission screw 38 to rotate, and the second transmission screw 38 drives the second transmission seat 37 to slide horizontally on the bottle conveying platform 3 through screw connection with the second transmission seat 37, thereby driving the first material-diverting cylinder 35 to slide horizontally on the bottle conveying platform 3, and then driving the first material-diverting plate 351 to slide horizontally on the bottle conveying platform 3.

[0034] Specifically, the feeding mechanism 5 is a plurality of conveyor chain devices connected end to end, and its structure is well-known in the prior art and will not be described in detail here.

[0035] Specifically, a column robotic arm 6 is provided on one side of the gantry 1 , and a plurality of suction cups are provided on the column robotic arm 6 . The structure of the column robotic arm 6 is a well-known prior art and will not be described in detail here.

[0036] The working principle of this automatic depalletizer is as follows: the material stack is placed on the conveyor chain device at the tail end, so that the material stack is transported to the side of the gantry 1 along the conveyor chain, and the column robot arm 6 grabs the pallet on the top of the material stack through the suction cup and moves the pallet away. At this time, the height of the material moving frame 23 is higher than the height of the material stack, and then the second motor 26 drives the material moving frame 23 to slide horizontally on the lifting frame 21 to above the material stack, and then the first motor 11 drives the lifting frame 21 to slide downward, and drives the transition plate 22 and the material moving frame 23 to move downward, so that the material on the top layer of the material stack passes through the material moving frame 23 and is located between several first clamping plates 232, so that the bearing surface of the transition plate 22 is flush with the supporting surface of the pallet below the material on the top layer of the material stack, and then the linear module 24 drives the transition plate 22 On the lifting frame 21, it slides toward the material stack so that the side end of the transition plate 22 is connected with the side end of the support plate, eliminating the gap between the transition plate 22 and the support plate. At the same time, several first clamping cylinders 231 drive several first clamping plates 232 to move toward the material on the top layer of the material stack at the same time and cooperate with each other to clamp the material. Then the second motor 26 drives the material moving frame 23 to slide toward the gantry 1 and moves the clamped material from the support plate to the transition plate 22. Then the first motor 11 drives the lifting frame 21 to drive the transition plate 22 and the material moving frame 23 to move downward, so that the bearing surface of the transition plate 22 is flush with the conveying surface of the first bottle conveying mesh belt 31. Then the linear module 24 drives the transition plate 22 to move toward the bottle conveying platform 3 so that the side end of the transition plate 22 is flush with the conveying surface of the first bottle conveying mesh belt 31. The head end of the material is connected to eliminate the gap between the transition plate 22 and the first bottle conveying mesh belt 31, and then the first material-diverting cylinder 35 drives the first material-diverting plate 351 to rise, and at the same time the second motor 26 drives the material-moving frame 23 to move toward the bottle conveying platform 3, passing under the first material-diverting plate 351 and horizontally moving the clamped material to the first bottle conveying mesh belt 31, realizing the unloading of one layer of material from the stack. By repeating the above process, the material on the stack can be unloaded layer by layer and transferred to the first conveyor mesh belt of the bottle conveying platform 3, realizing automatic unloading. During the unloading process, due to the horizontal sliding of the transition plate 22, the gap between the transition plate 22 and the support plate and the first bottle conveying mesh belt 31 is eliminated, so that the material can be more stably transferred from the support plate to the first bottle conveying mesh belt 31 during the unloading process. The transfer ensures the stability and efficiency of the unloading operation. After the material is transferred to the first bottle conveying mesh belt 31 and the first material stripping plate 351 is driven by the first material stripping cylinder 35 to move downward, the material is located between the first material stripping plate 351 and the material baffle plate 361. Then the fourth motor 34 drives the first material stripping plate 351 to move toward the second bottle conveying mesh belt 32. The material placed on the first bottle conveying mesh belt 31 is pushed by the first material stripping plate 351 to move toward the first bottle conveying mesh belt 31, so that the front row of materials moves from the first bottle conveying mesh belt 31 to the second bottle conveying mesh belt 32 and abuts against the material baffle plate 361. Then the material baffle cylinder 36 drives the material baffle plate 361 to move upward, so that the row of materials moved to the second bottle conveying mesh belt 32 is transported backward along with the second bottle conveying mesh belt 32.After the baffle plate 361 moves downward and resets, the first push plate pushes the next row of materials onto the second bottle conveying mesh belt 32 and contacts the baffle plate 361. By repeating the above process, the materials on the first bottle conveying mesh belt 31 are transferred to the second bottle conveying mesh belt 32 in alternate rows, and the second bottle conveying mesh belt 32 is transported backward to enter the next process of filling production.

[0037] In addition, a transition mesh belt 221 is provided on the transition plate 22, and the conveying surface of the transition mesh belt 221 constitutes the bearing surface of the transition plate 22. In the process of moving the material from the pallet to the transition mesh belt 221 and moving the material from the transition mesh belt 221 to the first bottle conveying mesh belt 31, the transition mesh belt 221 rotates with the movement of the material, reducing the friction between the material and the transition mesh belt 221 during the translation process, thereby ensuring the smoothness and stability of the material during translation, and also ensuring the smoothness and stability of the unloading operation.

[0038] In addition, the lifting frame 21 is fixedly connected to a limit frame 27 located on the side of the gantry 1 away from the bottle delivery platform 3 and below the material transfer frame 23. A second clamping cylinder 271 is provided on each side of the limit frame 27, and a second clamping plate 272 is fixedly connected to the output shaft of the second clamping cylinder 271. Before the unloading operation begins, the limit frame 27 moves upward with the lifting frame 21 to a position higher than the material stack. During the unloading operation, the limit frame 27 moves downward with the lifting frame 21 so that the material stack passes through the limit frame 27 and then passes into the material transfer frame 23. While the first clamping plate 232 clamps the uppermost layer of material, the second clamping cylinder 271 drives the second clamping plate 272 to clamp the lower layer of material, thereby ensuring the stability of the material stack when the uppermost layer of material is translated from the pallet to the bearing surface of the transition plate 22, thereby avoiding the occurrence of bottle overturning.

[0039] In addition, a finger cylinder 273 is fixedly connected to the second clamping plate 272. While the second clamping plate 272 clamps the second layer of materials, the finger cylinder 273 clamps the support plate under the top layer of materials, thereby ensuring the stability of the material stack during the unloading operation and avoiding the occurrence of bottle overturning.

[0040] In addition, the bottle conveying platform 3 is provided with a third bottle conveying mesh belt 39 located on one side of the tail end of the second bottle conveying mesh belt 32 and with a conveying direction perpendicular to the conveying direction of the second bottle conveying mesh belt 32. The bottle conveying platform 3 is provided with a second material-diverting cylinder 41 located on one side of the second bottle conveying mesh belt 32 and fixedly connected to the sliding seat of the rodless cylinder 40 provided on the bottle conveying platform 3 through a linear guide rail, and the output shaft of the second material-diverting cylinder 41 is fixedly connected to the second material-diverting plate 411 located above the tail end of the second bottle conveying mesh belt 32, and the second material-diverting cylinder 41 is transferred to the second bottle conveying mesh belt 32. When the material on the bottle mesh belt 32 moves to the tail end of the second bottle conveying mesh belt 32, the second material diverter cylinder 41 drives the second material diverter plate 411 to move upward to a position higher than the material. After the material passes under the second material diverter plate 411, the second material diverter plate 411 descends to the side of the material, and the rodless cylinder 40 drives the second material diverter cylinder 41 to mobilize the second material diverter plate 411 to move toward the third bottle conveying mesh belt 39, and pushes the material steadily row by row onto the third bottle conveying mesh belt 39 for single-row transportation, so as to cooperate with subsequent production processes.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
