Description
Technical Field
[0001] The utility model relates to the technical field of logistics equipment, and in particular to a logistics palletizer for transporting logistics packages. Background Art
[0002] A palletizer is an automated device that arranges and stacks packaged parcels in order. In the field of logistics, in order to facilitate automatic sorting of parcels, a palletizer is usually used to automatically stack parcels, thereby reducing the workload of workers. Palletizers under existing technologies are usually CNC-driven, use robotic arms and grippers to clamp parcels, and achieve automated operations through preset programs, so they are easy to operate.
[0003] According to the patent publication number CN111717670A: The present invention belongs to the technical field of logistics handling equipment, and discloses a logistics palletizer for logistics handling packages, including a stacking platform and a conveyor belt, wherein the stacking platform is located in front of the conveyor belt and close to the right side of the conveyor belt, and a first support rod is fixedly connected to the rear of the top of the conveyor belt bracket. This solution can adjust the horizontal distance between the two first clamping plates and the two second clamping plates through the left and right telescopic components, and can adjust the distance between the first clamping plate and the second clamping plate through the adjustment component, so as to realize the clamping of packages of different sizes, and realize automatic stacking through the cooperation of the conveyor belt, the transmission component, the mounting block, the first hydraulic push rod, the fixing bar, the left and right telescopic components, the first clamping plate, the second clamping plate and the adjustment component, so as to reduce labor and improve work efficiency, and solve the problem that the existing logistics palletizer cannot clamp packages exceeding the height and length of the clamping plate, which affects the stacking efficiency and reduces the practicality of the logistics stacker.
[0004] However, the stacking platform in the above patent does not have a structure to block the packages. Therefore, when the distance between the packages on the conveyor belt is relatively close, it is easy for the packages to move in advance before the previous package is completed, resulting in uncontrolled stacking. In the prior art, only a blocking rod horizontally mounted above the conveyor belt is usually used for blocking. When the packages placed on the conveyor belt are not perpendicular to the conveyor belt, the inclination angle of the packages and the lateral position deviation between different packages make it easy for the structure on the palletizer to clamp and place the packages to be empty. In addition, the inclined packages are prone to cause gaps between the clamping mechanism and the outside of the packages during the clamping process, which can easily cause the packages to fall and be damaged.

[0026] The parcel is conveyed toward the base 3 by the conveyor belt 11. When a parcel passes through the parcel limiting mechanism 2, the hydraulic lifting column 22 drives the hollow fixed column 21 to descend along the U-shaped telescopic column 23, so that the baffle 24 descends to the top of the conveyor belt 11 and blocks the remaining parcels. The rounded corners at the bottom of the baffle 24 prevent the baffle 24 from contacting the top of the conveyor belt 11 and scratching the surface of the conveyor belt 11. The elastic material of the baffle 24 provides a buffer for the downward force of the baffle 24, preventing the pressure generated when the baffle 24 contacts the conveyor belt 11 from bending the conveyor belt 11 and damaging the conveying function of the conveyor belt 11.

[0028] The stepper motor 12111 drives the screw rod 12111 to rotate, and drives the connecting rods 12122 on both sides to move synchronously through the connecting nut 12112, and the connecting rod 12122 drives the slider 12121 to move linearly along the limiting slide groove 1212 to prevent the connecting nut 12112 from rotating, and drives the movable rod 1223 to move through the connecting rod 12122, so that the vertical plate 122 moves and gradually pushes the packages so that the packages are arranged in a row, and the elastic rubber plate 1221 prevents the packages from being damaged by the push of the vertical plate 122. When the vertical plate 122 is harvested, the rubber buffer block 1222 prevents the vertical plate 122 from colliding with the outer wall of the fixed shell 121, causing damage.
[0029] like Figure 4As shown, the utility model provides a logistics palletizer for transporting logistics packages. A main motor 33 is fixedly installed on the inner wall of the base 3.

Two connecting blocks 1 321 are fixedly connected to the middle of the top of the protective shell 323.

[0030] The rotating mechanical arm 312 is driven to rotate downward by hydraulic cylinder 1 313, and the angle of the clamping mechanism 32 is adjusted by hydraulic cylinder 2 314. After the clamping plate 324 clamps the package, the main motor 33 drives the rotating roller 331 and the fixed mechanical arm 311 to rotate, so that the package is rotated to the top of the stacking shelf 4 and the package is placed on the top of the stacking shelf 4. The rotating roller 331 is limited and supported by the limiting ring 332 to prevent the pressure generated by the mechanical arm 31 on the main motor 33 from causing the output shaft of the main motor 33 to break and be damaged, and at the same time prevent the rotating roller 331 from vertical displacement.
[0031] like Figure 5As shown, the utility model provides a logistics palletizer for transporting logistics packages. An electric bidirectional screw rod 3231 is fixedly installed on the front side of the left wall of the inner part of the protective shell 323. The other end of the electric bidirectional screw rod 3231 is movably connected to the right side of the inner wall of the protective shell 323. Nuts 3232 are threadedly connected on the left and right sides of the outer wall of the electric bidirectional screw rod 3231. Slide rods 3234 are fixedly connected on the left and right sides of the inner part of the protective shell 323. The slide rods 3234 are arranged on the electric bidirectional screw rod 3231. At the rear side, the left and right sides of the outer wall of the slide bar 3234 are movably connected with hollow sliders 3233, the tops of the two clamping plates 324 are fixedly connected with U-shaped connecting rods 3242, the tops of the front and rear sides of the U-shaped connecting rods 3242 penetrate into the interior of the protective shell 323 and are respectively fixedly connected with the nuts 3232 and the bottoms of the hollow sliders 3233, the opposite surfaces of the two clamping plates 324 are fixedly connected with rubber anti-skid sheets 3241, and the outer walls of the rubber anti-skid sheets 3241 are provided with a plurality of oblique anti-skid grooves;
[0032] The electric bidirectional screw 3231 drives the nuts 3232 on both sides to move relative to each other at the same time, and the nut 3232 drives the hollow slider 3233 to move along the slide rod 3234, and drives the splint 324 to move in opposite directions and clamp the package through the U-shaped connecting rod 3242. The oblique anti-skid groove on the surface of the splint 324 generates an oblique friction force on the package, so that the trajectory of the package sliding downward under the influence of gravity is extended through the oblique anti-skid groove and the force of the package moving downward is buffered, thereby preventing the package from falling.
[0033] The following is a detailed description of the working principle of the logistics palletizer used to transport logistics packages.
[0034] like Figure 1-5As shown, the package is transported toward the base 3 through the conveyor belt 11. When a package passes through the package limiting mechanism 2, the hydraulic lifting column 22 drives the hollow fixed column 21 to descend along the U-shaped telescopic column 23, so that the baffle 24 descends to the top of the conveyor belt 11 and blocks the remaining packages. The rounded corners at the bottom of the baffle 24 prevent the baffle 24 from contacting the top of the conveyor belt 11 and scratching the surface of the conveyor belt 11. The elastic material of the baffle 24 provides a buffer for the downward force of the baffle 24, preventing the pressure generated when the baffle 24 contacts the conveyor belt 11 from bending the conveyor belt 11. As a result, the conveying function of the conveyor belt 11 is damaged, the stepper motor 1211 drives the screw rod 12111 to rotate, and the connecting rods 12122 on both sides are driven to move synchronously through the connecting nut 12112, and the connecting rod 12122 drives the slider 12121 to move linearly along the limiting slide groove 1212 to prevent the connecting nut 12112 from rotating, and the movable rod 1223 is driven to move by the connecting rod 12122, so that the vertical plate 122 moves and gradually pushes the packages, so that the packages are arranged in a row, and the elastic rubber plate 1221 is used to prevent the packages from being damaged by the push of the vertical plate 122. At 22:00, the outer wall of the fixed shell 121 is hit by the rubber buffer block 1222, causing damage. The rotating mechanical arm 312 is driven downward by the hydraulic cylinder 1 313, and the angle of the clamping mechanism 32 is adjusted by the hydraulic cylinder 2 314. The electric bidirectional screw rod 3231 drives the nuts 3232 on both sides to move relatively at the same time. The nuts 3232 drive the hollow slider 3233 to move along the slide rod 3234, and the U-shaped connecting rod 3242 drives the clamping plate 324 to move in the opposite direction and clamp the package. The oblique anti-skid groove on the surface of the clamping plate 324 produces an oblique anti-skid effect on the package. The friction force makes the trajectory of the package sliding downward under the influence of gravity extend through the oblique anti-skid groove and buffer the force of the package moving downward, thereby preventing the package from falling. After the clamping plate 324 clamps the package, the main motor 33 drives the rotating roller 331 and the fixed mechanical arm 311 to rotate, so that the package rotates to the top of the stacking shelf 4 and the package is placed on the top of the stacking shelf 4. The rotating roller 331 is limited and supported by the limiting ring 332 to prevent the pressure generated by the mechanical arm 31 on the main motor 33 from causing the output shaft of the main motor 33 to break and be damaged, and at the same time prevent the rotating roller 331 from vertical displacement.
[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
