Description

Technical Field

[0001] The present application relates to the technical field of palletizers, and in particular to a palletizer with adjustable palletizing height. Background Art

[0002] A palletizer is an automated device used to automatically stack items into stacks of a certain height. This technology is widely used in logistics, manufacturing, and other industries to improve efficiency and reduce labor costs. The design and application of a palletizer involves many aspects, including control system design, robot programming, dynamic analysis, and electrical control system design.

[0003] After beverages are produced and boxed, palletizers are often required to palletize and ship them. During the palletizing work at the beverage production site, the palletizer's palletizing height needs to be controlled to prevent the beverage boxes at the bottom of the stack from being excessively squeezed and deformed or even bursting. Therefore, one or two staff members are often required in the palletizing site of beverage production to manually monitor the palletizing height in real time. When the appropriate palletizing height is reached, the staff member operates the controller to shut down the palletizer for shipment. Different beverage boxes have different weights and volumes, so the palletizing height is also different, which requires real-time monitoring and appropriate regulation by the staff. Therefore, an intelligent palletizer is needed that can calculate the palletizing height according to the weight and volume of different beverage boxes and can adjust the palletizing height.

[0024] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant application and are not intended to limit the application. It should also be noted that, for ease of description, only the portions relevant to the application are shown in the accompanying drawings.

[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] Please refer to Figure 1 , an embodiment of the present application provides a palletizer with adjustable palletizing height, comprising a support frame 1, a moving mechanism 2, a linear motor 3, a clamping mechanism 4, a lifting platform 5 and a controller 6;

[0027] The support frame 1 includes a top frame 11 and a vertical rod 12; the top frame 11 is set in a square frame shape to provide support and working space for the mobile mechanism 2; the vertical rods 12 are fixedly provided at the four corners of the bottom surface of the top frame 11 in the vertical direction;

[0028] The top frame 11 is symmetrically provided with moving mechanisms 2 on both ends of the top surface along the width direction; a linear motor 3 is installed between the two moving mechanisms 2 along the width direction of the top frame 11; and a clamping mechanism 4 is installed on the bottom surface of the movable end of the linear motor 3.

[0029] In this embodiment, the two moving mechanisms 2 are jointly used to move the clamping mechanism 4 along the length direction of the top frame 11, and the linear motor 3 is used to move the clamping mechanism 4 along the width direction of the top frame 11. The moving mechanism 2 cooperates with the linear motor 3 to realize arbitrary movement of the clamping mechanism 4 in the horizontal direction. The clamping mechanism 4 can stably clamp and place beverage cartons, realizing the material picking and discharging functions of the palletizer. At the same time, the floor scale sensor 7 is used to detect the weight of the stacked cartons in real time, and then the controller 6 is used to control the height of the stacking pile, eliminating the process of manually starting and stopping the palletizer, saving manpower and increasing work efficiency.

[0030] In a preferred embodiment, the moving mechanism 2 includes a limiting frame 21, an installation box 22, a roller 23 and a wheel groove 24; the limiting frames 21 are fixedly provided on the top surfaces of both ends of the top frame 11 in the width direction along the length direction; a slide 25 is fixedly provided between the limiting frame 21 and the top frame 11; the length direction of the slide 25 is parallel to the length direction of the top frame 11; the installation box 22 is slidably provided inside the slide 25 along the length direction; the installation box 22 is rotatably provided with a roller 23 at one end away from the center of the top frame 11 along the width direction of the top frame 11; and two or more rollers 23 are evenly provided on the same installation box 22 along the length direction of the installation box 22;

[0031] The top surfaces of both ends of the top frame 11 along the width direction are fixedly provided with wheel grooves 24 along the length direction; the wheel grooves 24 are matched with the rollers 23 to provide guidance and limit functions for the rollers 23;

[0032] A linear motor 3 is installed between the two installation boxes 22 along the width direction of the top frame 11 ; both ends of the linear motor 3 along the length direction are fixedly connected to the two installation boxes 22 respectively.

[0033] Please refer to Figure 1 In this embodiment, the limiting frame 21 is set to an inverted U shape, forming a slide 25 between the top frame 11, and the slide 25 is used to move the installation box 22. The limiting frame 21 is used to limit the installation box 22 (the bottom surface of the installation box 22 is against the top surface of the top frame 11, and the top surface is against the limiting frame 21), so that it can only move along the length direction of the slide 25 (that is, the length direction of the top frame 11).

[0034] When the roller 23 rolls, the wheel groove 24 limits the moving direction of the roller 23 so that it can only move the installation box 22 along the length direction of the top frame 11 , and the roller 23 will not touch the limiting frame 21 when rolling.

[0035] In a preferred embodiment, a motor is installed inside the installation box 22 corresponding to the roller 23 ; the motor is in transmission connection with the corresponding roller 23 .

[0036] Please refer to Figure 1 In this embodiment, the motor is used to provide power for the rotation of the roller 23. The motor is installed corresponding to the roller. One motor can drive multiple rollers 23 to rotate, or multiple motors can be set to drive the rollers 23 to rotate respectively.

[0037] In a preferred embodiment, the clamping mechanism 4 includes a first fixed plate 31, a second fixed plate 32, a pressure plate 33 and a hydraulic rod 34; a movable end is provided on the bottom surface of the linear motor 3; the movable end of the linear motor 3 is fixedly provided with a first fixed plate 31 and a second fixed plate 32 on the bottom surfaces at both ends along the width direction of the top frame 11; a pressure plate 33 is provided between the first fixed plate 31 and the second fixed plate 32; a hydraulic rod 34 is installed on the first fixed plate 31 along the width direction of the top frame 11; there are more than two hydraulic rods 34; the movable ends of multiple hydraulic rods 34 are fixedly connected to the pressure plate 33.

[0038] Please refer to Figure 1 In this embodiment, when clamping the box body: the hydraulic rod 34 contracts, driving the pressure plate 33 away from the second fixed plate 32, and then the box body is moved between the pressure plate 33 and the second fixed plate 32 by the conveying device of the production equipment, and the hydraulic rod 34 extends, driving the pressure plate 33 close to the second fixed plate 32, and the pressure plate 33 cooperates with the second fixed plate 32 to press and clamp the box body.

[0039] When placing the box: the hydraulic rod 34 contracts, driving the pressing plate 33 away from the second fixing plate 32, and the box falls and is placed on the top surface of the lifting platform 5.

[0040] In a preferred embodiment, a lifting platform 5 is provided below the top frame 11 so as to be liftable; a floor scale sensor 7 is installed on the top surface of the lifting platform 5 .

[0041] Please refer to Figure 1 In this embodiment, the floor scale sensor 7 is used to detect the weight of the object on its top surface in real time, which is convenient for managing and regulating the stacking weight and height of the palletizer.

[0042] In a preferred embodiment, a controller 6 is installed on any vertical rod 12 ; the motor, the linear motor 3 , the hydraulic rod 34 , the lifting platform 5 and the floor scale sensor 7 are all electrically connected to the controller 6 .

[0043] Please refer to Figure 1 In this embodiment, the controller 6 uses an stm32 single-chip microcomputer in conjunction with a control program as the control core, which is used to control the working status of the motor, linear motor 3, hydraulic rod 34, lifting platform 5 and floor scale sensor 7.

[0044] When adjusting the stacking height: the floor scale sensor 7 detects the weight of the objects on it in real time, and the controller 6 compares the weight data sent back by the floor scale sensor 7 with the limit weight to intelligently adjust the stacking height.

[0045] How this application works:

[0046] The controller 6 controls the lifting platform 5 to rise, and the packed and boxed beverage boxes are conveyed by the conveying equipment to the bottom of the top frame 11. The clamping mechanism 4 clamps the box and places it on the floor scale sensor 7 on the top surface of the lifting platform 5. The floor scale sensor 7 detects the weight of the object on it in real time and transmits the detection data back to the controller 6. After a layer of beverage boxes is stacked, the controller 6 controls the lifting platform 5 to descend and continue the palletizing work of the beverage boxes on the upper layer. When the weight data sent back by the floor scale sensor 7 is close to the limit weight, the controller 6 stops the palletizing work and controls the lifting platform 5 to descend, so that the forklift can lift the shipping plate for shipment.
