Description

Technical Field

[0001] The utility model relates to the technical field of palletizing devices, and specifically relates to a multifunctional railing palletizing machine. Background Technique

[0002] In modern industrial production, palletizing is a crucial logistics link. In the early days, railing palletizing work mainly relied on manual labor. The background of this manual railing palletizing can be traced back to before the Industrial Revolution. At that time, the production scale was relatively small, and the handling and railing palletizing of materials were mainly carried out by manpower.

[0003] With the continuous development of industry, the production scale has gradually expanded, and the efficiency and accuracy of manual railing palletizing can no longer meet the requirements. To improve the efficiency and accuracy of railing palletizing, people began to introduce simple devices for railing palletizing. In the case of traditional manual railing palletizing, workers need to manually carry the materials to the designated position and perform railing palletizing according to specific rules. This method is not only inefficient but also prone to errors. Especially for some materials with large weight or irregular shapes, manual railing palletizing is more difficult. In addition, long-term manual railing palletizing work will cause worker fatigue and injuries, thereby affecting work efficiency and production quality.

[0004] To solve these problems, people began to research and develop and use simple devices for railing palletizing. These devices usually adopt mechanical structures or pneumatic devices, and through simple operations, they can complete the handling and railing palletizing of materials. Compared with the traditional manual railing palletizing method, the simple device railing palletizing can improve efficiency and accuracy and reduce the labor intensity of workers.

[0005] In terms of the technical level of manual railing palletizing and simple device railing palletizing, manual railing palletizing mainly relies on the physical strength and experience of workers. Workers need to have a certain amount of strength and skills to carry the materials to the designated position and perform railing palletizing. While simple device railing palletizing adopts some simple mechanical structures or pneumatic devices. Through the action of these devices, the automatic handling and railing palletizing of materials can be realized. For example, some simple devices can use pneumatic suction cups or manipulators to grab the materials and carry them to the designated position, and then perform railing palletizing through mechanical structures. The operation of these devices is relatively simple, and workers only need to perform some basic controls to complete the railing palletizing work.

[0006] When the existing railing palletizing device is in use, when facing materials with large differences in shape, size or weight, the device may not be able to effectively grasp, transport and palletize these materials. In order to adapt to different materials, the device may need to be frequently adjusted, such as replacing fixtures, adjusting the grasping force, etc., which not only increases the complexity and cost of operation, but also may lead to a decrease in production efficiency. In addition, it can only palletize according to pre-set programs and rules, lacking sufficient flexibility to handle complex palletizing tasks and the ability to adjust according to actual situations, unable to make dynamic adjustments according to real-time situations, and unable to effectively respond to these changes, thus affecting the production efficiency and quality.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 3, the utility model provides a technical solution: a multifunctional railing palletizer, which includes four support frames 1, two reinforcement frames 2 and a belt conveyor 3. The two ends of the reinforcement frame 2 are respectively fixedly connected to the opposite sides of the two support frames 1. The belt conveyor 3 is located between the opposite sides of the two support frames 1. A horizontal and vertical adjustment mechanism 400 is installed between the sides of the two support frames 1 away from the ground. A clamping mechanism 500 is installed between the sides of the two horizontal and vertical adjustment mechanisms 400;

[0025] Through the mutual cooperation of the reinforcement frame 2, the belt conveyor 3, the horizontal and vertical adjustment mechanism 400 and the clamping mechanism 500 on the support frame 1, the handling and stacking process of materials can be automatically completed, greatly shortening the operation time. The railing can be quickly and accurately grabbed, moved and placed at the designated position, greatly improving the production efficiency, and can work continuously without rest and pause, thus realizing the continuity and high efficiency of production. At the same time, it can ensure the precise palletizing and arrangement of the railing, and can ensure that the position and arrangement of each palletizing are the same, thus ensuring the product quality and improving the production efficiency.

[0026] In this embodiment, the horizontal and vertical adjustment mechanism 400 is a structure for precisely moving and placing materials at the designated position.

[0027] As Figure 1 , Figure 2 and Figure 3 shown, the horizontal and vertical adjustment mechanism 400 includes a hollow rectangular adjustment block 401 fixedly installed between the sides of the two support frames 1 away from the ground by bolts. A horizontal drive assembly is installed inside the hollow rectangular adjustment block 401. The outside of the horizontal drive assembly is connected to two threaded moving blocks 403 that are mirror-symmetrically connected to the inner side of the hollow rectangular adjustment block 401. A vertical drive assembly is connected between the sides of the four threaded moving blocks 403 close to the ground.

[0028] It should be noted that the horizontal drive assembly includes a protective housing 4021, a first servo motor 4022, and a threaded rod member 4023. One side of the protective housing 4021 is fixedly installed on one side of the hollow rectangular adjustment block 401 by bolts. One side of the first servo motor 4022 is fixedly installed inside the protective housing 4021. One end of the threaded rod member 4023 is fixedly connected to the output shaft of the first servo motor 4022, and the opposite end sequentially passes through the hollow rectangular adjustment block 401 and the threaded moving block 403 and extends to the inner side wall of the hollow rectangular adjustment block 401 and is rotationally connected to the hollow rectangular adjustment block 401 through a bearing, so as to stably drive the threaded moving block 403 to move. The two first servo motors 4022 achieve synchronous movement through a special synchronous controller. First, it receives feedback, receives position and speed information from the encoders or other feedback devices of the two motors, then uses a synchronous algorithm, based on a preset algorithm, to calculate the actions that each motor should take to maintain synchronization, and through drive control, sends the calculated control signals to the motor driver to adjust the speed and position of the motor.

[0029] It can be understood that the vertical drive assembly includes a support connection plate 4041 and an electric cylinder 4042. One side of the support connection plate 4041 is fixedly installed on the side of the four threaded moving blocks 403 close to the ground, and the outside of the electric cylinder 4042 is fixedly connected to the center inside the support connection plate 4041, so as to stably drive the clamping mechanism 500 to perform vertical lifting.

[0030] In this embodiment, the clamping mechanism 500 is a structure for quickly and accurately grasping the railing.

[0031] As Figure 1 and Figure 2 shown, the clamping mechanism 500 includes a fixed mounting plate 501 installed on the horizontal and vertical adjustment mechanism 400 and a control box 502 fixedly installed on the fixed mounting plate 501. A clamping drive assembly is installed inside the control box 502, and two adjustment clamping assemblies that are mirror-symmetrical and connected to the outside of the clamping drive assembly are provided. An auxiliary moving assembly connected to the control box 502 is connected between the inner sides of the two adjustment clamping assemblies.

[0032] It should be noted that the clamping drive assembly includes a connecting support plate 5031, a second servo motor 5032, and a bidirectional screw 5033. One side of the connecting support plate 5031 is fixedly installed on one side of the regulation box 502 by bolts. One side of the second servo motor 5032 is fixedly installed on one side of the connecting support plate 5031. One end of the bidirectional screw 5033 is fixedly connected to the output shaft of the second servo motor 5032, and the opposite end sequentially passes through the regulation box 502 and the adjustment clamping assembly and extends to the inner side wall of the regulation box 502 and is rotatably connected to the regulation box 502 through a bearing, so as to stably drive the two adjustment clamping assemblies to move in opposite or opposite directions synchronously.

[0033] It can be understood that the adjustment clamping assembly includes a moving adjustment block 5041 and a clamping plate 5042. The inner side of the moving adjustment block 5041 is threadedly connected to the outer side of the bidirectional screw 5033. The outer side of the moving adjustment block 5041 is in sliding fit with the inner side of the regulation box 502. One side of the clamping plate 5042 is fixedly connected to one side of the moving adjustment block 5041, so that the moving adjustment block 5041 can stably move on the outer side of the bidirectional screw 5033 under the thrust of the inner threaded rotation.

[0034] In addition, an adjustment hole 505 for the clamping plate 5042 to fit and slide is opened on one side of the regulation box 502 close to the ground, so as to improve the stability of the movement of the clamping plate 5042.

[0035] In this embodiment, the auxiliary moving assembly includes a support fixing block 5061 and a support rod member 5062. One side of the support fixing block 5061 is fixedly installed on one side of the regulation box 502 by bolts, and the number of regulation boxes 502 is two and they are symmetrically distributed in a mirror image. The two ends of the support rod member 5062 are respectively fixedly connected to the opposite sides of the two support fixing blocks 5061. The inner side of the clamping plate 5042 is in sliding connection and fits with the outer side of the support rod member 5062, so as to further improve the stability of the movement of the clamping plate 5042.

[0036] The working principle of the above embodiment is as follows:

[0037] When it is necessary to clamp and place the materials on the ground onto the belt conveyor 3, first start the first servo motor 4022. Driven by the rotating support of the bearing, the threaded rod member 4023 rotates stably, and drives the threaded moving block 403 to move stably within the hollow rectangular adjusting block 401 under the action of the rotational thrust of the inner thread, and at the same time drives the support connecting plate 4041 to move, and the electric cylinder 4042 moves accordingly. When the threaded moving block 403 moves to the specified position, the first servo motor 4022 stops driving. At this time, start the electric cylinder 4042 to drive the fixed mounting plate 501 to move towards the ground. When the material is located between the opposite sides of the two clamping plates 5042, start the second servo motor 5032. Driven by the rotating support of the bearing, the two moving adjusting blocks 5041 are driven to move towards each other or in opposite directions at the same time, and under the sliding connection action of the clamping plate 5042 and the support rod member 5062, the two clamping plates 5042 move stably towards each other and gradually clamp the material. Then, by operating in the reverse direction according to the above principle, the material can be clamped and placed on the belt conveyor 3.

[0038] Compared with the prior art: Through the mutual cooperation of the reinforcement frame 2 on the support frame 1, the belt conveyor 3, the horizontal and vertical adjustment mechanism 400 and the clamping mechanism 500, this multifunctional railing palletizer can automatically complete the handling and palletizing process of materials, greatly shortening the operation time. It can quickly and accurately grab, move and place the railings at the specified position, greatly improving the production efficiency. And it can work continuously without rest and pause, thus realizing the continuity and high efficiency of production. At the same time, it can ensure the precise palletizing and arrangement of the railings, and can ensure that the position and arrangement of each palletizing are the same, thus ensuring the product quality and improving the production efficiency. It solves the problem that the existing palletizing devices cannot adapt to materials with large differences in different shapes, sizes or weights, and the devices may not be able to effectively grab, handle and palletize the materials.

[0039] All the electrical components mentioned in the text are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed power connection technology and the provision of the power supply also belong to the common knowledge in this field, so this application will not elaborate in detail.
