An empty bottle palletizing device

Abstract

This invention discloses an empty bottle palletizing device, relating to the field of logistics packaging. It includes a first lifting mechanism and a second lifting mechanism. The bottom of the first lifting mechanism is equipped with a conveyor bed for transporting empty bottles. The second lifting mechanism is located at one end of the conveyor bed, and a placement tray for placing sealing and limiting components is provided on one side of the conveyor bed. The first lifting mechanism includes a gripping and placing mechanism that reciprocates above the placement tray and the conveyor bed. The end of the second lifting mechanism away from the conveyor bed is equipped with several stacking trays, and the second lifting mechanism reciprocates above the conveyor bed and the stacking trays.

Description

Technical Field

[0001] This invention belongs to the field of logistics packaging, and specifically relates to an empty bottle palletizing device. Background Technology

[0002] Liquid beverages such as alcoholic beverages and soft drinks are generally sold in bottles. This means that after production and inspection, the beverages need to be filled into empty bottles, sealed, labeled, and then transported for sale. To reduce transportation costs and improve efficiency, empty bottles are placed on pallets after production and inspection. These pallets are then stacked layer by layer and finally transported by forklift to trucks for centralized transport to the beverage factory, where they are filled.

[0003] Traditional palletizing methods typically involve manual tray placement, but manual palletizing suffers from low efficiency, high breakage rates, and waste during the process.

[0004] To address this, the factory adopted palletizing machines to replace manual palletizing. For example, Chinese patent application number "CN202010135050.6" discloses "An Empty Bottle Palletizing Device," which states: "An empty bottle palletizing device is provided, comprising: a conveying mechanism for inputting empty bottles, and a bottle-blocking mechanism for concentrating the input empty bottles into an array; a palletizing mechanism for grabbing the arrayed empty bottles from the conveying mechanism and placing them on a pallet automatically transferred to the palletizing mechanism, and then palletizing multiple groups of empty bottles for centralized transport. In this invention, empty bottles are arranged by the conveying mechanism, and then the palletizing mechanism grabs the empty bottles, places them on the pallet, stacks them layer by layer, and then transports the entire assembly to a designated location for loading and unloading. During the palletizing process, the pallet is automatically placed and removed, freeing up manpower and enabling the overall transport of scattered empty bottles, improving efficiency, reducing damage to the empty bottles."

[0005] However, this design still has drawbacks. When the pallets are stacked, the bottom of the pallet is in direct contact with the bottle neck of the empty bottle below. When the stack shakes, the bottom of the pallet will continuously wear down the bottle neck, which makes the bottle neck highly likely to be damaged during transportation, leading to an increased breakage rate. Summary of the Invention

[0006] To address the above-mentioned shortcomings, the purpose of this invention is to provide an empty bottle palletizing device that solves the problem in the prior art where the bottom of the pallet directly contacts the bottle opening of the empty bottle on the lower layer when the pallets are stacked, causing the bottle opening to be easily damaged.

[0007] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0008] An empty bottle palletizing device includes a first lifting mechanism and a second lifting mechanism. The bottom of the first lifting mechanism is provided with a conveyor bed for conveying empty bottles, and the second lifting mechanism is located at one end of the conveyor bed. A placement tray for placing sealing and limiting components is provided on one side of the conveyor bed. The first lifting mechanism includes a gripping and placing mechanism that moves back and forth between the placement tray and the conveyor bed. The end of the second lifting mechanism away from the conveyor bed is provided with a plurality of stacking trays, and the second lifting mechanism moves back and forth between the conveyor bed and the stacking trays.

[0009] The gripping and placing mechanism includes a fixed frame, an air compressor is installed on the top of the fixed frame, and several air intake nozzles are installed on the bottom of the fixed frame. The air intake nozzles are connected to the air compressor and are arranged in strips.

[0010] The first lifting mechanism includes a first support column and a second support column, with a first crossbeam installed between the first and second support columns. The first crossbeam has parallel first and second grooves on its side, with the second groove located between the first groove and the conveyor bed. The inner wall of the first groove has a protruding structure. The fixing frame includes a first plate, a connecting plate, and a second plate from top to bottom. A drive motor is installed on the top of the first plate, and a power gear is installed on the power output end of the drive motor. The power gear meshes with the protruding structure. The air compressor and the air intake nozzle are located at the top and bottom of the second plate, respectively.

[0011] A cylinder is installed on one side of the connecting plate, and the telescopic end of the cylinder is connected to the top of the second plate.

[0012] The second lifting mechanism includes a reciprocating clamping mechanism. A gas compression mechanism is installed on the top of the clamping mechanism, and a pair of first and second arc-shaped plates are installed on the bottom of the clamping mechanism. The concave surfaces of the first and second arc-shaped plates face each other, and a gap is provided between the first and second arc-shaped plates. Both the first and second arc-shaped plates are covered with airbags, and the airbags are connected to the gas compression mechanism.

[0013] The clamping mechanism is provided with multiple suction cups in its circumferential direction, and the suction cups are connected to the gas compression mechanism.

[0014] The second lifting mechanism includes a first column, a second column, a third column, and a fourth column. A first cross arm is installed between the first and second columns, and a second cross arm is installed between the third and fourth columns. Limiting grooves are provided on the sides of both the first and second cross arms, and the two limiting grooves are arranged opposite to each other. A concave-convex mechanism is provided in the limiting groove. A movable cross beam is installed between the first and second cross arms. A power motor is installed on the top of the movable cross beam, and a power gear is installed on the output end of the power motor. The power gear is meshed with the concave-convex mechanism. The bottom of the movable cross beam is connected to a clamping mechanism.

[0015] The first column is equipped with a brake motor at its top, and a first lead screw is installed between the brake motor and the bottom of the first column. One end of the first cross arm is threadedly connected to the first lead screw.

[0016] The conveyor bed is equipped with a first gantry and a second gantry with the same structure. The first lifting mechanism is located between the first gantry and the second gantry. A hydraulic cylinder is installed on the side wall of the first gantry, and a baffle is installed on the telescopic end of the hydraulic cylinder.

[0017] After adopting the above technical solution, the beneficial effects of the present invention are:

[0018] First, by setting up a first lifting mechanism to grab and place the sealing limit component, direct contact between the bottle mouth and the stacking tray is avoided, thereby reducing the damage rate of empty bottles during transportation. Second, the grabbing and placement of empty bottles and the stacking tray are both carried out by a second lifting mechanism, which ensures the working efficiency of the second lifting mechanism.

[0026] Example:

[0027] like Figure 1-4As shown, this solution provides an empty bottle palletizing device, including a first lifting mechanism and a second lifting mechanism. The bottom of the first lifting mechanism is equipped with a conveyor bed 1 for transporting empty bottles. The second lifting mechanism is located at one end of the conveyor bed 1. A placement tray 2 for placing sealing limiting components 3 is provided on one side of the conveyor bed 1. The first lifting mechanism includes a gripping and placing mechanism 5, which reciprocates above the placement tray 2 and the conveyor bed 1. At the end of the second lifting mechanism away from the conveyor bed 1, several stacking trays 4 are provided, and the second lifting mechanism reciprocates above the conveyor bed 1 and the stacking trays 4. To reduce damage to the bottle neck caused by the stacking trays 4 squeezing the bottle neck, this solution introduces a sealing limiting component 3 and a first lifting mechanism for installing the sealing limiting component 3. Empty bottles are transported to the bottom of the first lifting mechanism via the conveyor bed 1. At this time, the reciprocating gripping and placing mechanism 5 first moves towards the placement tray 2 containing the sealing limiting component 3, and then moves towards the conveyor bed 1 after gripping the sealing limiting component 3. At this point, the empty bottles are arranged in an array on the conveyor bed 1. The gripping and placing mechanism 5 only needs to move downwards to place the sealing limiting member 3 at the bottle opening. After placement, the conveyor bed 1 restarts, transporting the empty bottles towards the second lifting mechanism. The second lifting mechanism first sends the stacking tray 4 to the designated position, then moves towards the conveyor bed 1, grips the empty bottle, returns to the designated position, and places the empty bottle on the stacking tray 4. Then, the gripping and stacking tray 4 process is repeated. Because of the sealing limiting member 3 at the bottle opening, the stacking tray 4 cannot directly contact the bottle opening. When shaking occurs, the sealing limiting member 3 acts as a buffer, thus protecting the bottle opening from damage.

[0028] To facilitate the gripping of the sealing limiting component 3, the gripping and placing mechanism 5 includes a fixed frame. An air compressor 52 is mounted on the top of the fixed frame, and several suction nozzles 511 are mounted on the bottom of the fixed frame. The suction nozzles 511 are connected to the air compressor 52 and are arranged in a strip. The sealing limiting component 3 in this design is elongated, with a groove at its bottom corresponding to the bottle opening, and a hard, smooth plate 31 at its top. The elongated structure and the groove at the bottom limit the movement of multiple empty bottles, preventing them from becoming disorganized during transport. The hard, smooth plate 31 facilitates the gripping of the sealing limiting component 3 by the suction nozzles 511, reducing the risk of loose gripping due to air leakage. During operation, the air compressor 52 draws air through the suction nozzles 511 to grip the sealing limiting component 3. After placement, the air compressor 52 controls the air recirculation to place the sealing limiting component 3 at the bottle opening.

[0029] To facilitate the reciprocating lateral movement of the gripping and placing mechanism 5 on the first lifting mechanism, the first lifting mechanism includes a first support column 501 and a second support column 502. A first crossbeam 503 is installed between the first support column 501 and the second support column 502. The side of the first crossbeam 503 has a parallel first groove and a second groove. The second groove is located between the first groove and the conveyor bed 1. A protruding structure is provided on the inner wall of the first groove. The fixing frame includes a first plate 53, a connecting plate, and a second plate 54 from top to bottom. A drive motor 55 is installed on the top of the first plate 53. A power gear is installed on the power output end of the drive motor 55. The power gear meshes with the protruding structure. The air compressor 52 and the suction nozzle 511 are located at the top and bottom of the second plate 54, respectively.

[0030] In order to facilitate the up-and-down movement of the gripping and placing mechanism 5, a cylinder 56 is installed on one side of the connecting plate, and the telescopic end of the cylinder 56 is connected to the top of the second plate 54.

[0031] To facilitate the second lifting mechanism in gripping empty bottles, the second lifting mechanism includes a reciprocating gripping mechanism 6. A gas compression mechanism 61 is installed on the top of the gripping mechanism 6, and a pair of first arc-shaped plates 62 and second arc-shaped plates 63 are installed on the bottom of the gripping mechanism 6. The concave surfaces of the first arc-shaped plate 62 and the second arc-shaped plate 63 face each other, and a gap is provided between the first arc-shaped plate 62 and the second arc-shaped plate 63. Both the first arc-shaped plate 62 and the second arc-shaped plate 63 are covered with air bladders, and the air bladders are connected to the gas compression mechanism 61. When it is necessary to grab an empty bottle, the clamping plates formed by the first arc plate 62 and the second arc plate 63 move towards each other and grab the bottle mouth. After the grabbing is completed, the airbag is inflated by the gas compression mechanism 61 and fills the space between the first arc plate 62 and the second arc plate 63. At this time, the grabbing work is completed. When placing the bottle, the airbag only needs to be deflated, and then the first arc plate 62 and the second arc plate 63 move in opposite directions to place the empty bottle on the stomp plate 4.

[0032] To facilitate the gripping of the stacking plate 4, the gripping mechanism 6 is equipped with multiple suction cups 64 circumferentially, which are connected to the gas compression mechanism 61. The suction cups 64 are mounted on the side wall of the gripping mechanism 6, and one end of each suction cup is connected to the gas compression mechanism 61 via a pipe. When gripping the stacking plate 4, the gripping mechanism 6 presses down. When the bottom of the suction cup 64 contacts and squeezes the top of the stacking plate 4, the gas compression mechanism 61 begins to extract air. At this time, the air pressure between the bottom of the suction cup 64 and the stacking plate 4 decreases, and the stacking plate 4 is tightly gripped by the suction cup 64. Then, the gripping mechanism 6 rises, transferring the stacking plate 4 towards the direction of the conveyor bed 1. In this design, several first arc-shaped plates 62 and second arc-shaped plates 63 are surrounded by several suction cups 64. The suction cups 64 work separately from the first arc-shaped plates 62 and second arc-shaped plates 63. That is, when the suction cups 64 transfer the stomping plate 4, the first arc-shaped plates 62 and second arc-shaped plates 63 are stationary. When the first arc-shaped plates 62 and second arc-shaped plates 63 grab empty bottles, the suction cups 64 stop working. In this design, the height of the suction cup 64 is higher than the height of the first arc plate 62 and the second arc plate 63. Therefore, the first arc plate 62 and the second arc plate 63 will not obstruct the suction cup 64 from gripping the plate 4. Since the empty bottle has a certain height, and since the first arc plate 62 and the second arc plate 63 only grip the bottle opening, the total height of the first arc plate 62 and the empty bottle is greater than the height of the suction cup 64. In addition, the suction cup 64 is arranged around the first arc plate 62 and the second arc plate 63, so the suction cup 64 cannot obstruct the gripping and placement of the empty bottle.

[0033] The second lifting mechanism operates on the same principle as the first lifting mechanism, both aiming to perform horizontal and vertical movements. Therefore, the second lifting mechanism includes a first column 601, a second column 602, a third column 603, and a fourth column 604. A first crossarm 605 is installed between the first column 601 and the second column 602, and a second crossarm 606 is installed between the third column 603 and the fourth column 604. Limiting grooves are provided on the sides of both the first and second crossarms 605 and 606, with the two limiting grooves facing each other. A concave-convex mechanism is provided within each limiting groove. A movable crossbeam 65 is installed between the first and second crossarms 605 and 606. A power motor 66 is installed on the top of the movable crossbeam 65, and a power gear is installed at the output end of the power motor 66. The power gear meshes with the concave-convex mechanism. The bottom of the movable crossbeam 65 is connected to a clamping mechanism 6.

[0034] Preferably, a brake motor 607 is mounted on the top of the first column 601, and a lead screw is installed between the brake motor 607 and the bottom of the first column 601. One end of the first cross arm 605 is threadedly connected to the lead screw. Similarly, the second column 602, the third column 603, and the fourth column 604 are all equipped with brake motors 607 and lead screws, and both ends of the first cross arm 605 and the second cross arm 606 are threadedly connected to the lead screw. When the brake motor 607 rotates, it drives the lead screw to rotate, and the rotation of the lead screw will drive the first cross arm 605 and the second cross arm 606 to move up and down. To avoid the columns obstructing the movement of the cross arms, notches are provided on the opposite sides of the first column 601 and the second column 602, and the same applies to the third column 603 and the fourth column 604.

[0035] To facilitate the pause of empty bottle movement and the placement of sealing limiters 3, the top of the conveyor bed 1 is also equipped with a first gantry 7 and a second gantry 8 with the same structure. The first lifting mechanism is located between the first gantry 7 and the second gantry 8. A hydraulic cylinder 71 is installed on the side wall of the first gantry 7, and a baffle 72 is installed on the telescopic end of the hydraulic cylinder 71.

[0036] To facilitate the collection of empty bottles, a horn-shaped gathering plate 9 is installed at the end of the conveyor bed 1 away from the second lifting mechanism.

[0037] To facilitate the arrangement of empty bottles into an array, several isolation plates for isolating empty bottles are installed between the gathering plate 9 and the second lifting mechanism.

[0038] In summary, the advantages of this device are: First, by setting up a first lifting mechanism to grab and place the sealing limiting component 3, direct contact between the bottle mouth and the stacking tray 4 is avoided, thereby reducing the damage rate of empty bottles during transportation. Second, the grabbing and placement of the empty bottle and the stacking tray 4 are both carried out by a second lifting mechanism, which ensures the working efficiency of the second lifting mechanism.

[0039] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the scope of protection of this invention.
