Description

Technical Field

[0001] The utility model relates to the technical field of dairy product production, and more specifically, it relates to a packing box palletizing device for dairy product production. Background Technique

[0002] Dairy products refer to various foods processed from the milk of mammals. These products retain the nutritional components in the milk and at the same time enhance the flavor and shelf life through processes such as fermentation, curdling, and dehydration. Common dairy products include: milk, yogurt, cheese, butter, etc. Dairy products are an important part of the diet of many people around the world, providing nutrients such as high-quality protein, calcium, and vitamins.

[0003] Packing box palletizing is an automated process that involves using a palletizing robot or other automated palletizing equipment to stack packaged products, such as boxes, bags, or other containers, into neat stacks for easy storage or transportation. This process usually occurs at the end of the production line as part of the packaging process. Palletizing can greatly improve efficiency, reduce dependence on manual labor, and at the same time ensure the speed, accuracy, and repeatability of the palletizing process.

[0004] In the existing packing box palletizing device, the packing boxes on the conveyor belt are identified through a vision system or sensors, and the manipulator moves to the selected position of the packing box. By installing a force sensor on the manipulator, the movement process of the clamping plate driven by the electric telescopic rod is controlled to ensure that the clamping force during the clamping process is moderate, neither too tight nor too loose, to avoid the situation that if the clamping force is too small, the packing box may slip during the palletizing process; conversely, if the clamping force is too large, it may damage the surface or structure of the packing box. However, after the sensor has been used for a long time, the accuracy of the sensor will change, which will cause the clamping mechanism to clamp too tightly or too loosely. Clamping too tightly will damage the outer surface of the packing box, resulting in relatively small losses, while clamping too loosely will cause the packing box to fall from the air, resulting in the dairy products contained inside being damaged, causing greater economic losses.

[0005] Therefore, in order to solve the above technical problems, this application proposes a packing box palletizing device for dairy product production. Content of the Utility Model

[0006] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a packing box palletizing device for dairy product production.

[0007] To achieve the above purpose, the utility model provides the following technical solutions: The packing box palletizing device for dairy product production includes a manipulator and a protective plate. One end of the manipulator is connected to a mounting seat, and the other end of the manipulator is connected to a base;

[0008] A clamping mechanism is arranged below the mounting seat and is used for clamping the packing box;

[0009] A linkage mechanism is provided below the mounting base and is used to drive the protective plate to rotate;

[0010] The linkage mechanism includes a first motor and a second motor. The mounting ends of the first motor and the second motor are both connected to the mounting base. The output end of the first motor is connected to a first screw rod. A first threaded seat is threadedly connected to the outer surface of the first screw rod. The output end of the second motor is connected to a second screw rod. A second threaded seat is threadedly connected to the outer surface of the second screw rod. The bottoms of the first screw rod and the second screw rod are both connected to a second gear. The teeth of the second gear are meshed with the teeth of a first gear. The bottom of the first gear is connected to the protective plate. Two limiting rods are connected to the bottom of the mounting base. One ends of the two limiting rods respectively penetrate through the first threaded seat and the second threaded seat.

[0011] Preferably, the first screw rod and the second screw rod are screw rods with opposite threads and the same other parts, ensuring that the moving distances of the first threaded seat and the second threaded seat are the same when moving.

[0012] Preferably, two bearings are connected to the bottom of the mounting base. One ends of the two bearings are both connected to a rotating shaft. One end of the rotating shaft is connected to the first gear.

[0013] Preferably, the number of teeth of the first gear is eight times that of the second gear, so that when the first gear rotates half a turn, the second gear rotates four turns.

[0014] Preferably, the clamping mechanism includes an electric telescopic rod. The mounting end of the electric telescopic rod is connected to the first threaded seat. The telescopic end of the electric telescopic rod is connected to a moving plate. A clamping plate is connected to one side of the second threaded seat.

[0015] Preferably, rubber pads are connected to one sides of the clamping plate and the moving plate. The rubber pads play a role in increasing friction and protection.

[0016] Preferably, a limiting block is connected to the bottom of the limiting rod to prevent the first threaded seat and the second threaded seat from detaching from the limiting rod.

[0017] Preferably, a weighing sensor is arranged in the protective plate below the clamping plate. When the packaging box slides off the clamping plate and falls onto the protective plate, it contacts the weighing sensor, thereby prompting the information that the packaging box has slid onto the protective plate on the display screen of the manipulator, reminding the operator to repair the force sensor.

[0018] Compared with the prior art, the present utility model has the following beneficial effects:

[0019] 1. By setting up a linkage mechanism, the rotation of the first screw rod and the second screw rod can be driven by controlling the first motor and the second motor, the movement of the first threaded seat and the second threaded seat can be driven, the rotation of the first gear can be driven, and the rotation of the protective plate can be driven. When the clamping mechanism clamps and moves the packaging box, there is always a protective plate under the packaging box for protection, thus solving the problem that due to the change in the accuracy of the force sensor, if the clamping mechanism clamps too loosely, the packaging box will fall from the air, resulting in the destruction of the dairy products contained inside and causing relatively large economic losses.

[0020] 2. Through the clamping mechanism and the rubber pad, the movement of the moving plate can be driven by controlling the electric telescopic rod to clamp packaging boxes of different sizes, and the rubber pad plays a role in increasing friction and protection.

[0021] 3. By setting up a weighing sensor, when the packaging box slides off the clamping plate and falls onto the protective plate, it will come into contact with the weighing sensor, so as to prompt the information that the packaging box has slid onto the protective plate on the display screen of the manipulator, reminding the operator to repair the force sensor manually.

[0028] As Figure 1 - Figure 4As shown in the figure, the utility model provides a carton palletizing device for dairy product production, which includes a manipulator 1 and a protective plate 4. One end of the manipulator 1 is connected to a mounting seat 2, and the other end of the manipulator 1 is connected to a base 21;

[0029] A clamping mechanism is arranged below the mounting seat 2 and is used for clamping the carton;

[0030] A linkage mechanism is arranged below the mounting seat 2 and is used for driving the protective plate 4 to rotate;

[0031] The linkage mechanism includes a first motor 20 and a second motor 19. The mounting ends of the first motor 20 and the second motor 19 are both connected to the mounting seat 2. The output end of the first motor 20 is connected to a first screw rod 6. A first threaded seat 14 is threadedly connected to the outer surface of the first screw rod 6. The output end of the second motor 19 is connected to a second screw rod 7. A second threaded seat 9 is threadedly connected to the outer surface of the second screw rod 7. The bottoms of the first screw rod 6 and the second screw rod 7 are both connected to a second gear 15. The teeth of the second gear 15 are meshed with the teeth of a first gear 5. The bottom of the first gear 5 is connected to the protective plate 4. Two groups of limiting rods 16 are connected to the bottom of the mounting seat 2. One ends of the two groups of limiting rods 16 respectively penetrate through the first threaded seat 14 and the second threaded seat 9;

[0032] The clamping mechanism includes an electric telescopic rod 13. The mounting end of the electric telescopic rod 13 is connected to the first threaded seat 14. The telescopic end of the electric telescopic rod 13 is connected to a moving plate 12. One side of the second threaded seat 9 is connected to a clamping plate 10;

[0033] Rubber pads 11 are connected to one sides of the clamping plate 10 and the moving plate 12;

[0034] Two groups of bearings 18 are connected to the bottom of the mounting seat 2. One ends of the two groups of bearings 18 are both connected to a rotating shaft 3. One end of the rotating shaft 3 is connected to the first gear 5;

[0035] The first screw rod 6 and the second screw rod 7 are screw rods with opposite threads and the same other parts;

[0036] The number of teeth of the first gear 5 is eight times the number of teeth of the second gear 15;

[0037] A limiting block 17 is connected to the bottom of the limiting rod 16;

[0038] A force sensor is installed on the manipulator 1 to control the movement process of the electric telescopic rod 13 driving the moving plate 12; according to the size of the packaging box, under the action of the force sensor, the electric telescopic rod 13 is controlled to adjust the distance between the moving plate 12 and the clamping plate 10. The rubber pad 11 plays a role in increasing friction and protection. After the moving plate 12 and the clamping plate 10 clamp the packaging box, control the first motor 20 to drive the first screw rod 6 to rotate, and at the same time control the second motor 19 to drive the second screw rod 7 to rotate in the opposite direction, driving the first thread seat 14 and the second thread seat 9 to move upward. The limiting rod 16 restricts the moving direction of the first thread seat 14 and the second thread seat 9. While the first thread seat 14 and the second thread seat 9 move upward, the first motor 20 and the second motor 19 drive the two groups of second gears 15 to rotate, thereby driving the two groups of first gears 5 to rotate. Since the number of teeth of the first gear 5 is eight times that of the second gear 15, when the second gear 15 rotates four circles, the first gear 5 rotates half a circle. After the second gear 15 rotates four circles, the first thread seat 14 and the second thread seat 9 move upward by a certain distance. When the first gear 5 rotates half a circle, it drives the protection plate 4 to rotate 180 degrees. The mounting seat 2 moves to the designated position under the control of the manipulator 1. The protection plate 4 plays a role in protection during transportation. After reaching the designated position, control the first motor 20 and the second motor 19 to drive the first screw rod 6 and the second screw rod 7 to rotate in the opposite direction to the previous one, which can drive the first thread seat 14 and the second thread seat 9 to move downward, and at the same time drive the protection plate 4 to rotate. By controlling the electric telescopic rod 13, the packaging box can be unloaded;

[0039] As Figure 2 and Figure 3 shown, a weighing sensor 8 is arranged inside the protection plate 4 below the clamping plate 10;

[0040] When the packaging box slides off the clamping plate 10 and falls onto the protection plate 4, it touches the weighing sensor 8, so as to prompt the information that the packaging box has slid onto the protection plate 4 on the display screen for controlling the manipulator 1, and remind the operator to repair the force sensor.
