Description

Technical Field

[0001] The present invention relates to the technical field of logistics, and in particular to a logistics palletizer for transporting logistics packages. Background Art

[0002] Logistics palletizer is a kind of equipment used for automatic palletizing and picking, which is widely used in modern logistics warehousing systems. It realizes automatic palletizing, picking and sorting by scanning and identifying the barcode or QR code of the goods, improving the efficiency of warehouse management and reducing manual operation errors. Traditional devices mostly use migration components and lifting components to migrate the mechanical claws for handling and palletizing.

[0003] A patent with publication number CN111717670A in the traditional technology discloses a logistics palletizer for logistics handling packages, including a stacking platform and a conveyor belt. The stacking platform is located in front of the conveyor belt and close to the right side of the conveyor belt. A first support rod is fixedly connected to the rear of the top of the conveyor belt support. The above scheme can adjust the horizontal distance between the two first clamps and the two second clamps through the left and right telescopic components, and the distance between the first clamp and the second clamp can be adjusted through the adjustment component, so as to achieve the clamping of packages of different sizes. Through the cooperation of the conveyor belt, the transmission component, the mounting block, the first hydraulic push rod, the fixed bar, the left and right telescopic components, the first clamp, the second clamp and the adjustment component, automatic stacking is achieved, labor is reduced, and work efficiency is improved. The problem that the existing logistics palletizer cannot clamp packages that exceed the height and length of the clamp, which affects the stacking efficiency and reduces the practicality of the logistics stacker is solved.

[0004] However, there are some problems with traditional devices: traditional devices use electric push rods for lifting. When storing and stacking in the warehouse, the express boxes need to be stacked, and the mechanical claw needs to be moved to the bottom of the storage space for grabbing. When installing the stacking device on the roof, an electric push rod with half the roof height is required to control the mechanical claw to descend, thereby reducing the stacking height of the express boxes and failing to make reasonable use of limited space.

[0017] Compared with the prior art, the present invention provides a logistics palletizer for transporting logistics packages, which has the following beneficial effects:

[0018] 1. This logistics palletizer used to transport logistics packages realizes efficient handling and stacking of logistics packages by combining a top gantry, a lifting system and a traction rope. The gantry is fixed on the top of the storage space. Through the displacement in the horizontal plane, it flexibly controls the precise positioning of the mechanical claw in the horizontal and vertical directions, avoiding the occupation of ground space and improving space utilization. The lifting system drives the traction rope through the lifting motor to control the up and down movement of the mechanical claw. The traction rope is retracted and released around the driving wheel to realize the grabbing and stacking of packages. In order to prevent the traction rope from shaking, a movable column and a linkage plate structure are designed to make the traction rope form a stable support similar to a rigid rod to ensure the accuracy of the package grabbing and placement process.

[0019] 2. The logistics palletizer used for transporting logistics packages realizes flexible adjustment and stable positioning of the linkage plate and the movable column through the limit assembly. The pinion drives the upper gear ring to move by rotation. An arc-shaped limit groove is opened in the gear ring, which cooperates with the limit rod to make the wing plate rotate synchronously. When the mechanical claw moves down, the limit motor controls the wing plate to form a large hole, allowing the traction rope and the movable column to pass smoothly, so as to carry out the package grabbing or placing operation. When pressure needs to be applied to the movable column, the limit motor further adjusts the wing plate to reduce the large hole to a small hole. At this time, only the steel rope can pass, and the movable column is compressed to form a rigid fixed rod, which effectively prevents the shaking of the traction rope.

[0020] 3. The logistics palletizer used to transport logistics packages installs a drive motor inside the support seat to provide clamping power for the mechanical claw. A fixed plate is fixed at the bottom, and splints are installed on both sides of the fixed plate for clamping packages. The driving gear in the center of the fixed plate is connected to the splint. When the driving motor is started, the gear rotates and the splint slides synchronously to achieve the clamping or release of the logistics box. A lifting plate is installed at the bottom of the splint, and a second electric push rod is provided on the upper part of the lifting plate to control the height of the splint to adapt to different logistics boxes. An infrared rangefinder is installed in the lifting plate to monitor the height of the clamped object in real time to ensure accurate adjustment of the splint. In addition, a silicone plate is fixed on the inside of the lifting plate to enhance the gripping friction, improve the stability of the splint, and prevent the package from sliding. This design improves the gripping accuracy and stability of the mechanical claw.

[0021] The present invention solves the problem of large space occupation of traditional palletizing equipment by using a planar moving system of a gantry and a traction rope driven by a lifting motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] Example:

[0044] Reference Figure 1-Figure 11 A logistics palletizer for transporting logistics packages, including a gantry 1 for fixing on the top of a storage space for transporting logistics packages, the gantry 1 is fixedly installed with a driving component 2 for winding a rope, the driving component 2 winds up a traction rope 3, and the lower part of the traction rope 3 is fixedly connected with a mechanical claw 4 for grabbing the logistics package; wherein the traction rope 3 includes a steel rope 301, and a plurality of movable columns 302 are equidistantly slidably installed on the outside of the steel rope 301; wherein a linkage plate 6 that can constrain the movable column 302 is also installed on the gantry 1, and the upper part of the movable column 302 is in active contact with the linkage plate 6, and when the linkage plate 6 applies a downward force to the movable column 302, the plurality of movable columns 302 are pressed and contacted in sequence to form a rod-like structure.

[0045] The above-mentioned logistics palletizer for transporting logistics packages:

[0046] Gantry 1 and plane displacement control:

[0047] The gantry 1 is a frame structure fixed on the top of the storage space. The movement of the output end of the gantry 1 in the horizontal plane enables the mechanical claw 4 to be accurately positioned in both the horizontal and vertical directions. Since the gantry 1 occupies the top of the storage space, it will not affect the logistics operation space on the ground, ensuring efficient use of space.

[0048] When it is necessary to grab or stack packages, the output end of the gantry 1 is driven to move. The gantry 1 is responsible for moving the mechanical claw 4 to the designated grabbing or placement point. This flexible movement method can cover a larger operating area.

[0049] When the traction rope 3 is released downward, the mechanical claw 4 descends as the traction rope 3 is loosened until it contacts the package.

[0050] Stability control of the traction rope 3: In order to prevent the traction rope 3 from shaking during the lifting process, the design introduces the structure of the movable column 302 and the linkage plate 6. Multiple movable columns 302 are installed equidistantly on the outside of the traction rope 3, and the movable columns 302 can interact with the linkage plate 6 during the up and down sliding process. When the mechanical claw 4 descends, the linkage plate 6 presses down through the electric push rod, forcing the movable columns 302 to contact closely in turn, forming a structure similar to a rigid fixed rod, thereby limiting the swing of the traction rope 3. This design avoids the error caused by the swing of the traction rope 3 during the lifting process of the mechanical claw 4, thereby ensuring the position accuracy of the package during the grasping and stacking process.

[0051] Move up and stack: After the grabbing action is completed, the traction rope 3 is reeled in, and the mechanical claw 4 rises with the package to the preset stacking height. The gantry 1 moves to the designated stacking position again, and then the control system releases the mechanical claw 4 to place the package firmly in the stacking area.

[0052] In this embodiment, in order to enable the linkage plate 6 to flexibly pass through the steel rope 301 or through the movable column 302, and then realize that multiple movable columns 302 are closely fitted to form a rod-shaped object, the driving component 2 includes a lifting motor 201, a support frame 203 is installed on the gantry, the lifting motor 201 is fixedly installed on the upper part of the support frame 203, and a first electric push rod 5 is fixedly installed on the other side of the upper part of the support frame 203. The output end of the first electric push rod 5 passes through the bottom of the support frame 203 and is fixedly connected to the linkage plate 6. A limit assembly 7 is provided inside the linkage plate 6. The limit assembly 7 includes a limit motor 701, the limit motor 701 is fixed at the lower part of the linkage plate 6, and the output end of the limit motor 701 passes through the linkage plate 6 and is fixedly connected to a pinion 702, and the pinion 702 is rotatably installed on the upper part of the linkage plate 6. The driving component 2 includes a lifting motor 201, and the output end of the lifting motor 201 is fixedly connected to a driving wheel 202, and the traction rope 3 drives the outside of the wheel 202. The pinion 702 is meshed with a gear ring 703, which is rotatably mounted on the upper part of the linkage plate 6. The gear ring 703 is provided with arc-shaped limiting grooves 704 evenly arranged in the circumferential direction. The linkage plate 6 is fixedly connected with a plurality of limiting rods 705 at positions corresponding to the limiting grooves 704. The limiting rods 705 are slidably connected with the limiting grooves 704. A plurality of fin plates 707 are evenly rotatably mounted on the upper part of the linkage plate 6. A plurality of connecting plates 706 corresponding to the fin plates 707 are rotatably mounted on the inner side of the gear ring 703. The connecting plates 706 are rotatably connected with the fin plates 707 on the side away from the gear ring 703. The plurality of fin plates 707 are driven by the limiting motor 701 to form small holes 708 for passing the steel rope 301 or large holes 709 for passing the movable column 302.

[0053] The limit assembly 7 is designed to achieve flexible adjustment and stable positioning between the linkage plate 6 and the movable column 302. The limit motor 701 of the limit assembly 7 is installed at the lower part of the linkage plate 6, and its output end is connected to a pinion 702. The pinion 702 is fixed on the linkage plate 6 and can rotate by the motor drive. The pinion 702 is meshed with a toothed ring 703 installed on the upper part of the linkage plate 6, and the toothed ring 703 surrounds the circumference of the linkage plate 6 and can rotate with the rotation of the pinion 702.

[0054] The inner circumference of the gear ring 703 is uniformly provided with arc-shaped limiting grooves 704, which are used to cooperate with the limiting rod 705 for sliding. The limiting rod 705 is fixed on the upper part of the linkage plate 6 and cooperates with the limiting groove 704, so that the gear ring 703 can stably drive the fin plate 707 to move synchronously during the rotation process. When the limiting motor 701 is started, it drives the pinion 702 to rotate, and the pinion 702 transmits power through the gear ring 703, driving the connecting plate 706 to rotate, and the connecting plate 706 further causes the fin plate 707 to rotate and adjust.

[0055] Process of forming the large hole 709: When the mechanical claw 4 moves down normally, the limit motor 701 controls the fin plate 707 to rotate to a specific angle, so that a large hole 709 is formed between the multiple fin plates 707, allowing the traction rope 3 and the movable column 302 to pass smoothly. In this state, the mechanical claw 4 can move down freely to grab or place the package.

[0056] Process of forming small hole 708: When the movable column 302 needs to be compressed, the limit motor 701 controls the fin plate 707 to further rotate, and the large hole 709 is reduced to a small hole 708. The size of the small hole 708 is just enough for the steel rope 301 to pass through, but the movable column 302 cannot pass through. The multiple movable columns 302 are compressed under the restriction of the fin plate 707 to form a rigid fixed rod to prevent the traction rope 3 from shaking during operation.

[0057] In this embodiment, in order to realize multi-point logistics box grabbing and palletizing, preferably, the gantry 1 includes a fixed frame 101 for fixing on the upper part of the roof, and transverse motors 105 are fixedly installed on both sides of the fixed frame 101, and transverse screw rods 106 are fixedly installed on the output end of each transverse motor 105. The two transverse screw rods 106 are rotatably installed inside the two sides of the fixed frame 101. A movable frame 104 is slidably installed at the lower part of the fixed frame 101, and the upper part of the movable frame 104 is respectively screwed with two transverse screw rods. A longitudinal motor 102 is fixedly installed on one side of the movable frame 104, and a longitudinal screw rod 103 is fixedly connected to the output end of the longitudinal motor 102. The longitudinal screw rod 103 is rotatably installed inside one side of the movable frame 104. A slider 107 is slidably installed on one side of the movable frame 104, and the longitudinal screw rod 103 is screwed inside the slider 107. The side of the slider 107 away from the longitudinal screw rod 103 is fixedly installed with a support frame 203.

[0058] Through the coordination of the transverse motor 105, the longitudinal motor 102 and the screw rod, the mechanical claw 4 can be moved in the plane at the top of the storage space. Specifically, the transverse motor 105 drives the transverse screw rod 106 to rotate, and the screw rod drives the movable frame 104 under the fixed frame 101 to slide horizontally through the screw structure, so as to realize the movement of the mechanical claw 4 in the left and right directions. At the same time, the longitudinal motor 102 drives the longitudinal screw rod 103 to rotate, and drives the mechanical claw 4 to move in the front and back directions through the screw connection between the slider 107 and the longitudinal screw rod 103. In this way, the mechanical claw 4 can be accurately positioned and moved at any position in the storage space. It effectively improves the flexibility and operating efficiency of the equipment, enabling it to adapt to storage spaces of different sizes and layouts, and complete the tasks of efficient grasping and stacking of packages.

[0059] In this embodiment, in order to achieve the reduction of the force on the movable column 302 and the fit with the lower movable column 302, preferably, a slide plate 303 is fixedly connected to the outside of the steel rope 301, the movable column 302 is hollow, the slide plate 303 is connected to the upper wall of the inner cavity of the movable column 302 through a spring 304, and the slide plate 303 is slidably installed inside the movable column 302.

[0060] The linkage plate 6 is pressed down by the electric push rod, forcing the slide plate 303 to drive the movable column 302 to move downward. When the slide plate 303 is subjected to the downward pressure from the linkage plate 6, the spring 304 is compressed, and the contact surface between the slide plate 303 and the inside of the movable column 302 slides, thereby achieving the smooth descent of the movable column 302. In this process, the movable column 302 gradually fits tightly with the other movable columns 302 below through sliding, forming a stable "fixed rod" structure. The resilience of the spring 304 and the sliding characteristics of the slide plate 303 are effectively utilized to ensure that the movable column 302 can move downward smoothly under force, and form a rigid structure when necessary, avoiding the swinging problem of the steel rope 301 during the lifting process.

[0061] In this embodiment, in order to realize the grabbing of the logistics box, preferably, the mechanical claw 4 includes a support base 401, the support base 401 is fixed at the lower part of the steel rope 301, a driving motor 402 is fixedly installed inside the support base 401, a fixed plate 403 is fixedly connected to the lower part of the support base 401, and clamping plates 404 are symmetrically slidably installed inside the two sides of the fixed plate 403.

[0062] A driving gear 405 is rotatably mounted at the center of the fixed plate 403 . The driving gear 405 is meshed and connected with the two clamping plates 404 , respectively. The driving motor 402 passes through the fixed plate 403 and is fixedly connected with the driving gear 405 .

[0063] A driving motor 402 is installed inside the support base 401, and the motor is responsible for providing power for the clamping action of the mechanical claw 4. A fixed plate 403 is fixedly connected to the lower part of the support base 401, and two clamping plates 404 are symmetrically slidably installed on both sides of the fixed plate 403, and the clamping plates 404 are used to clamp the package. A driving gear 405 is installed at the center of the fixed plate 403, and the driving gear 405 is respectively meshed and connected with the two clamping plates 404. The output shaft of the driving motor 402 passes through the fixed plate 403 and is connected to the driving gear 405. When the driving motor 402 is started, the driving gear 405 starts to rotate, and the gear drives the two clamping plates 404 to slide inward or outward at the same time, thereby realizing the action of clamping or releasing the logistics box.

[0064] It is possible to grasp packages of different sizes, and the sliding stroke of the clamping plate 404 can be flexibly adjusted according to the size of the package to ensure the stability of the package during transportation and stacking.

[0065] In this embodiment, in order to realize the driving of the plate body 4041 and the height adjustment of the plate body 4041 to adapt to logistics boxes of different sizes and heights, the splint 404 includes a plate body 4041, two plate bodies 4041 are plug-in arranged, a tooth plate 4046 is fixedly connected to the inner side of the plate body 4041, the tooth plate 4046 is meshingly connected to the driving gear 405, and a lifting plate 4043 is slidably installed on the lower part of the side of the plate body 4041 away from the driving gear 405, a second electric push rod 4042 is fixedly installed on the upper part of the plate body 4041, and the output end of the second electric push rod 4042 is fixedly connected to the upper part of the lifting plate 4043, an infrared rangefinder 4045 is fixedly installed inside the lifting plate 4043, and a silicone plate 4044 is fixedly connected to the inner side of the lifting plate 4043.

[0066] In order to adapt to logistics boxes of different sizes and heights, the structure of the clamping plate 404 of the mechanical claw 4 is optimized. Each clamping plate 404 includes a plug-in plate body 4041, and a tooth plate 4046 is fixedly connected to the inner side of the plate body 4041, and the tooth plate 4046 is meshed with the driving gear 405. When the driving motor 402 is running, the rotation of the driving gear 405 drives the tooth plate 4046 to move, thereby causing the clamping plate 404 to perform a clamping or releasing action.

[0067] In order to adjust the height of the clamping plate 404, a lifting plate 4043 is slidably installed on the lower part of the side of the clamping plate 404 away from the driving gear 405. A second electric push rod 4042 is fixedly installed on the upper part of the lifting plate 4043, and the output end of the electric push rod is fixedly connected to the upper part of the lifting plate 4043. By controlling the extension and contraction of the second electric push rod 4042, the lifting plate 4043 can move up and down, thereby adjusting the height of the clamping plate 404 to adapt to logistics boxes of different heights.

[0068] An infrared rangefinder 4045 is fixedly installed inside the lifting plate 4043. The infrared rangefinder 4045 can monitor the height of the clamped object in real time to ensure that the clamping plate 404 can be accurately adjusted to a suitable height for grasping. In addition, a silicone plate 4044 is fixedly connected to the inside of the lifting plate 4043. The silicone plate 4044 provides additional grasping friction, enhances the grasping stability of the clamping plate 404 on the package, and prevents the package from sliding during transportation.

[0069] In the present invention, the gantry 1 fixed on the top is combined with the horizontal and longitudinal motors 102 to drive the screw rod, so as to realize the flexible movement of the mechanical claw 4 in the plane and cover the entire working area.
