Description

Technical Field

[0001] The present invention relates to the field of automatic sorting and reorganization equipment for warehouse storage, and particularly to a double-pallet automatic sorting and reorganization system. Background Art

[0002] At present, in some units of the cigarette-making and packing section of tobacco enterprises, after the cigarette materials are combined and palletized and stored in the high-bay warehouse, they are then delivered to the cigarette-making and packing units by AGV cars to ensure production supply. Now, due to cost reduction and efficiency improvement, the labor cost of reorganizing the palletizing of cigarette materials is reduced, and no more re-palletizing is carried out. Since the cigarette materials are no longer re-palletized, after the materials are unloaded from the vehicle at the factory, they are directly stacked on the pallets in the high-bay warehouse for storage. As a result, when these pallets are recycled and stored in the warehouse, there are double pallets with the high-bay warehouse pallets at the bottom and the pallets of the material manufacturers at the top.

[0003] To meet the process requirements and solve the double-pallet phenomenon, currently, operators have been manually removing the manufacturer pallets in the double pallets, which is time-consuming and laborious, affects efficiency, and has great potential safety hazards in production. In addition, the current equipment process requires that the pallets be returned to the warehouse one by one, and after being palletized by the palletizing unit, they are stored in the high-bay warehouse for standby. Summary of the Invention

[0004] The purpose of the present invention is to provide a double-pallet automatic sorting and reorganization system to solve the problems of manpower and safety in manually removing double pallets, and to meet the subsequent process requirements of single-pallet coding, sorting, and storage for different pallets.

[0005] To achieve the above technical purpose, the present invention provides a double-pallet automatic sorting and reorganization system, which has an M-shaped bracket. The bracket includes a first column, a second column, a third column, and a cross beam. The rejection station of the pallet transportation track is located between the first column and the second column. Among them: a propulsion cylinder is horizontally arranged on the cross beam and is drivingly controlled and connected to the computer system control unit. A photoelectric position sensor is longitudinally arranged inside the first column and is signal-controlled and connected to the computer system control unit. The photoelectric position sensor includes a lower-layer sensor and an upper-layer sensor. The push rod of the propulsion cylinder is connected to a pushing mechanism. The pushing mechanism corresponds to the position of the upper pallet in height, and the inner side of the pushing mechanism abuts against the outer surface of one side of the upper pallet. A guide rail is horizontally arranged on the cross beam, and a grasping mechanism is also arranged in the middle of the cross beam. The grasping mechanism has a grasping surface that cooperates with the other side of the upper pallet. The pushing mechanism and the grasping mechanism are horizontally arranged on both sides of the upper pallet, and the pushing mechanism and the grasping mechanism are respectively slidably connected to the cross beam along the guide rail. And the lower pallet enters the automatic palletizing area located downstream of the rejection station along the pallet transportation track, and a pallet storage area for stacking and accommodating the upper pallet is provided between the second column and the third column.

[0006] The system of the present invention is located at the rejection station, and provides a pallet storage area and an automatic coding area connected thereto. By automatically identifying single-layer and double-layer pallets and grabbing the upper pallet, the lower pallet directly continues to enter the coding area, and the upper pallet can return to the rejection station to enter the coding area as needed, or, as needed, such as the pallets of the supplier manufacturer, directly enter the pallet storage area for separate storage and processing. The entire system is fully automatic and does not require manual intervention. The system not only greatly reduces the labor intensity of workers, but also effectively avoids production safety accidents. The system can also reject the upper manufacturer's pallets through program instructions, and only retain the normal coding of the factory's pallets.

[0007] As a further improvement, the second column is provided with a lifting cylinder longitudinally arranged and connected to the driving control of the computer system control unit, the end of the lifting cylinder is in contact with the lower surface of the upper tray and lifts the upper tray upward; the lower sensor corresponds to the height of the lower tray, and the upper sensor corresponds to the height of the upper tray.

[0008] As a further improvement, the push rod has a pre-pushing distance, a reorganization pushing distance and a rejection pushing distance, and the rejection pushing distance corresponds to the tray storage area.

[0009] As a further improvement, a travel sensor cooperating with the pushing mechanism and the grabbing mechanism is installed on the crossbeam, and the travel sensor is connected to the computer system control unit for signal control.

[0010] As a further improvement, the computer system control unit controls the push rod to reach the pre-push distance, the reorganization push distance and the rejection push distance, and in the tray storage area, the computer system control unit controls the gripping mechanism to release the upper tray.

[0011] As a further improvement, a height detection photoelectric switch connected to the signal control of the computer system control unit is also arranged in the tray storage area, and the height detection photoelectric switch detects the stacking height of the upper tray in the tray storage area.

[0012] As a further improvement, the end of the lifting cylinder is a roller, and the roller rotates axially along the lateral movement direction of the upper tray.

[0013] As a further improvement, when the pre-pushing distance is reached, the lifting cylinder is lifted, and the pre-pushing distance is 150 mm and the lifting distance is 50 mm.

[0014] As a further improvement, the computer system control unit internally has a pallet group counter corresponding to the stacking height of the upper pallets in the pallet storage area and a preset value, and a pallet group counting display and a buzzer connected to the computer system control unit are also arranged in the pallet storage area.

[0015] As a further improvement, the photoelectric position sensor is an infrared height position induction switch, the preset value is 6 layers, and the propulsion cylinder, the lifting cylinder and the grasping mechanism are also signal-controlled and connected to a manual control unit.

[0016] This system can automatically shift the upper-layer manufacturer pallets above, and according to the system instructions, automatically remove the upper-layer manufacturer pallets, or automatically place the later-entered pallets in the lower layer onto the pallet track and enter the palletizing area to ensure the normal palletizing and returning of pallets in the high-bay warehouse. Through this device, it can quickly and effectively judge double pallets. When it is judged as a double pallet, the present invention can automatically remove the upper pallet, reducing the labor intensity of manually handling the upper pallet and improving the stability, smoothness and effectiveness of the pallet returning work in the high-bay warehouse.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Such as Figures 1 to 3As shown in the figure, the present invention provides a double-tray automatic sorting and recombination system, which has an M-shaped bracket 2. The bracket 2 includes the first, second, and third columns and crossbeams. The rejection station of the tray conveying track 1 is located between the first and second columns, where: A propulsion cylinder 3 drivingly controlled and connected to the computer system control unit 6 is horizontally arranged on the crossbeam. A photoelectric position sensor 7 signal-controlled and connected to the computer system control unit 6 is longitudinally arranged inside the first column. And the photoelectric position sensor 7 includes a lower-layer sensor and an upper-layer sensor. The push rod 4 of the propulsion cylinder 3 is connected to a pushing mechanism 9. The pushing mechanism 9 corresponds to the position of the upper tray in height, and the inner side of the pushing mechanism 9 abuts against and contacts the outer surface of one side of the upper tray. A guide rail 11 is horizontally arranged on the crossbeam. A grasping mechanism 10 is also arranged in the middle of the crossbeam. The grasping mechanism 10 has a grasping surface that cooperates with the other side of the upper tray. The pushing mechanism 9 and the grasping mechanism 10 are horizontally arranged on both sides of the upper tray, and the pushing mechanism 9 and the grasping mechanism 10 are respectively slidably connected to the crossbeam along the guide rail 11. And the lower tray enters the automatic palletizing area 15 located downstream of the rejection station along the tray conveying track 1. A tray storage area 16 for stacking and accommodating the upper tray is provided between the second and third columns.

[0022] The system of the present invention is located at the rejection station and provides a connected tray storage area 16 and automatic palletizing area 15. By automatically identifying single- and double-layer trays and grasping the upper tray, the lower tray directly continues to enter the palletizing area, and the upper tray can return to the rejection station to enter the palletizing area as needed, or directly enter the tray storage area for separate storage treatment as needed, such as trays from supplier manufacturers. The entire system is fully automated and requires no manual intervention. The system not only greatly reduces the labor intensity of workers but also effectively avoids the occurrence of production safety accidents. The system can also reject the upper manufacturer trays through program instructions and only retain the trays of the factory for normal palletizing.

[0023] As a further improvement, a lifting cylinder 12 drivingly controlled and connected to the computer system control unit 6 is longitudinally arranged on the second column. The end of the lifting cylinder 12 abuts against and contacts the lower surface of the upper tray and jacks up the upper tray. The lower-layer sensor corresponds to the height of the lower tray, and the upper-layer sensor corresponds to the height of the upper tray.

[0024] As a further improvement, the push rod 4 has a pre-pushing distance, a recombination pushing distance, and a rejection pushing distance, and the rejection pushing distance corresponds to the tray storage area 16.

[0025] As a further improvement, a travel sensor 14 cooperating with the pushing mechanism 9 and the grasping mechanism 10 is installed on the cross beam, and the travel sensor 14 is connected to the computer system control unit 6 through signal control.

[0026] As a further improvement, the computer system control unit 6 controls the push rod 4 to reach the pre-pushing distance, the re-organizing pushing distance, and the rejecting pushing distance, and in the tray storage area 16, the computer system control unit 6 controls the grasping mechanism 10 to release the upper tray.

[0027] As a further improvement, a height detection photoelectric switch 17 connected to the computer system control unit 6 through signal control is also arranged in the tray storage area 16, and the height detection photoelectric switch 17 detects the stacking height of the upper trays in the tray storage area 16.

[0028] As a further improvement, the end of the lifting cylinder 12 is a roller 13, and the roller 13 rotates around the axis along the transverse movement direction of the upper tray.

[0029] As a further improvement, when the pre-pushing distance is reached, the lifting cylinder 12 jacks up, and the pre-pushing distance is 150 mm, and the jacking-up distance is 50 mm.

[0030] As a further improvement, the computer system control unit 6 internally has a tray group counter 20 corresponding to the stacking height of the upper trays in the tray storage area 16 and a preset value, and a tray group counting display 18 and a buzzer 19 connected to the computer system control unit 6 are also arranged in the tray storage area 16.

[0031] As a further improvement, the photoelectric position sensor 7 is an infrared height position induction switch, the preset value is 6 layers, and the propulsion cylinder 3, the lifting cylinder 12, and the grasping mechanism 10 are also connected to the manual control unit 5 through signal control.

[0032] This system can automatically shift the upper trays of the manufacturer, automatically reject the upper trays of the manufacturer according to the system instructions, or automatically place the lower incoming trays onto the tray track and enter the palletizing area, ensuring the normal palletizing and returning of the trays in the high-bay warehouse. Through this device, the double trays can be quickly and effectively judged. When it is judged as double trays, the present invention can automatically reject the upper trays, reducing the labor intensity of manually handling the upper trays and improving the stability, smoothness, and effectiveness of the tray return work in the high-bay warehouse.

[0033] A double-tray automatic sorting and recombination system provided by the present invention mainly includes a bracket, a sliding guide rail located on a cross beam, a main cylinder serving as a propulsion cylinder, a pushing mechanism linked to the push rod of the cylinder, a grasping mechanism, lift rollers, a lift roller cylinder, an infrared double-tray detection, an infrared tray positioning detection, and a control system.

[0034] When the system executes the program for fully recycling and recombining trays, that is, when both the upper and lower trays are recycled and recombined, the system detects a double-layer tray at position number 4115 on the tray transport track. The system displaces the upper tray through the pushing mechanism and the grasping mechanism, and only the single-layer lower tray is allowed to pass. The lower tray leaves position number 4115 and first enters the automatic palletizing area (number 4116) of the next station, and the recycling of the lower tray is completed through the pallet stacker therein; then the upper tray returns to position 4115 through system homing, and then also enters the automatic palletizing area (number 4116) of the next station, and the recycling and recombination of the lower tray are completed through the pallet stacker therein, finally achieving the process requirements of separately recycling each of the upper and lower layers of trays one by one.

[0035] When the system executes the program for removing the manufacturer's trays, that is, removing the manufacturer's trays located on the upper layer and stacking them separately, while the trays on the lower layer enter the pallet stacker to complete the recycling of the lower trays, forming different recycling methods for the two types of trays. When executing the removal program, the system detects a double-layer tray at position number 4115 on the tray transport track. The system displaces the upper tray through the pushing mechanism and the grasping mechanism, and only the single-layer lower tray is allowed to pass. The lower tray leaves position number 4115 and first enters the pallet stacker to complete the recycling of the lower tray. The upper tray is pushed by the system to the tray storage area, then released and stacked in the tray storage area. When the stacking number reaches a preset value, for example, 6 layers, the stacked manufacturer's trays are transported away from the tray storage area. The entire system is fully automatic and does not require manual intervention. The system not only greatly reduces the labor intensity of workers, but also effectively avoids the occurrence of production safety accidents. The system can also achieve two sorting operations through program instructions, that is, the upper and lower layer trays enter the pallet stacker respectively, or the upper layer trays are removed, and the upper manufacturer's trays are removed, and only the trays of this factory are normally palletized.

[0036] In a preferred embodiment, the operation steps of the system include:

[0037] 1. Power on the equipment and it is in the standby state.

[0038] 2. When the infrared sensor detects that a tray passes below and the upper detection probe does not detect a double-layer tray, the system stands by without taking any action;

[0039] 3. When the infrared sensor detects that a tray has passed and the upper detection probe detects a double tray, the tray rejection program is executed. The cylinder retracts, and the push rod is linked to the jacking device to move the tray outwards. After moving outwards by 150 mm, the lift roller moves upwards by 50 mm under the action of the cylinder to separate the upper and lower trays. The main cylinder continues to retract, the upper tray leaves the tray track, and the lower tray passes through normally and enters the next station, the 4116 tray palletizing area.

[0040] 4.1. If the system program requires the execution of the full tray recycling and reorganization program, after the lower tray moves to the 4116 position, the infrared probe detects that the tray track is empty, the cylinder resets and advances to the position on the tray track, the lift roller descends, and the grasping mechanism (such as a pneumatic pawl) releases. The upper tray is placed at the 4115 position of the tray track and enters the 4116 tray palletizing area along the conveyor track to complete the sorting and reorganization of the upper tray, and the system stands by.

[0041] 4.2. If the system program requires the execution of the manufacturer's tray rejection program, the cylinder continues to retract, and the upper tray completely leaves the 4115 area and reaches the storage area of the manufacturer's tray. The grasping mechanism (such as a pneumatic pawl) releases, and the upper tray is placed at the manufacturer's tray placement position and stacked layer by layer. When the lower tray reaches the 4116 position and the infrared probe detects that the tray track is empty, the cylinder advances to the standby position, and the grasping mechanism and the lift roller return to their original positions, and the system stands by.

[0042] In a preferred embodiment, when the stacking quantity of the trays of the supplier manufacturer is greater than or equal to 6, the height detection photoelectric switch gives a prompt alarm, and the tray group is removed manually.

[0043] It should be understood that the scope to be protected by the present invention is not limited to the non-restrictive embodiments, and it should be understood that the non-restrictive embodiments are only illustrated as examples. The substantial scope of protection required by this application is more reflected in the scope provided by the independent claims and their dependent claims.
