Description

Technical Field

[0001] The invention relates to the technical field of plate edge banding, in particular to a plate feeding mechanism for furniture edge banding skins. Background Art

[0002] In the furniture manufacturing process, edge banding is widely used to beautify the edges of boards and enhance their durability. Existing board feeding mechanisms for furniture edge banding mostly use mechanical conveying systems, which usually include a fixed-direction conveyor belt or roller, and are driven by an electric motor to achieve the conveying and positioning of the boards. The basic structure of these traditional feeding mechanisms usually consists of a conveying platform, a mechanical clamp, an electric drive device, and a simple control system. Among them, the conveying platform transports the boards from the loading point to the edge banding equipment through a fixed-direction conveyor belt or roller, and the mechanical clamp is used to fix and position the boards to ensure the accuracy and consistency of the edge banding process. However, with the continuous improvement of production efficiency and product quality requirements in furniture manufacturing, traditional feeding mechanisms have exposed many shortcomings in practical applications and are in urgent need of improvement and optimization.

[0003] First, the existing feeding mechanisms mostly use a single-direction mechanical drive method, which limits the movement and turning of the feeding device. This fixed-direction conveying method is difficult to flexibly respond to the needs of transferring plates between different workstations in a workshop environment with a complex production line layout or limited space. The transfer of plates between different workstations often requires frequent adjustments to the feeding path, which increases the residence time of the plates during the transfer process and reduces the overall operating efficiency of the production line. In addition, the fixed-direction conveying system has limitations in space utilization, making it difficult to achieve efficient layout in a small or complex production environment, resulting in waste of production space and unreasonable equipment layout.

[0004] Secondly, the traditional feeding mechanism usually relies on a single motor drive, and the control method is relatively simple, making it difficult to achieve multi-directional and precise control of the board. In actual edge banding operations, the positioning and posture adjustment of the board have an important impact on the edge banding quality. However, when processing boards of different specifications and shapes, the feeding device with a single drive method is difficult to achieve flexible posture adjustment and stable fixation, resulting in increased errors in the edge banding process, affecting the appearance and quality of the final product.

[0005] In view of this, research and improvement are carried out on the existing problems, and a board feeding mechanism for furniture edge banding is provided to solve the current problems. The purpose is to achieve the purpose of solving the problems and improving the practical value through this technology. Summary of the invention

[0006] The present invention aims to solve one of the technical problems existing in the prior art or related technology. To this end, the technical solution adopted by the present invention is: A sheet material feeding mechanism for furniture edge banding comprises: a conveying seat, on the inner side of which a plurality of servo motors are fixedly mounted, the output end of the servo motor is drivingly connected to an omnidirectional wheel set; a support seat, fixed to the top surface of the conveying seat, and used for supporting the sheet material; a transfer mechanism, comprising a rotating drum, an axle rod, a rotary plug cylinder and a plurality of plunger rods; an adsorption kit, fixed to the surface of the rotating drum, on which a plurality of suction cups are provided; a first drive motor, fixedly mounted on the surface of the conveying seat; a second drive motor, fixedly mounted on the surface of the conveying seat; an adjustment seat, used for adjusting the installation height of the first drive motor and the second drive motor; a guide sleeve ring, fixedly connected to one side of the rotary plug cylinder, a three-way connecting hole being provided in the guide sleeve ring; a bevel seat, on the surface of which a ring groove is provided; a sliding sleeve head, connected to one end of a slider; a slider, slidably mounted in the ring groove, and the slider is connected to the end of the plunger rod through the sliding sleeve head.

[0007] In a preferred example, the present invention can be further configured as follows: Servo controller configuration: A servo controller for controlling a servo motor is provided on the inner side of the conveying seat, and the servo controller is used to uniformly control the coordinated actions of the servo motor, the first drive motor and the second drive motor, thereby realizing fully automated operation of the feeding mechanism.

[0008] Omnidirectional wheel set structure: The omnidirectional wheel set adopts the McNay mother wheel structure to enhance the movement flexibility and stability of the feeding mechanism in all directions.

[0009] Suction cup material: The suction cup is made of silicone material to improve adaptability to the surface of the plate and reduce friction damage, ensuring stable adsorption of the plate during transportation.

[0010] Inclined surface seat shape: The surface of the inclined surface seat is V-shaped. Through the cooperation of the ring groove and the slider, the plunger rod can perform periodic telescopic movement along the V-shaped inclined surface when the rotary plug cylinder rotates, further enhancing the negative pressure adsorption force.

[0011] Plunger rod motion control: One end of the plunger rod is connected to the slider through a sliding sleeve head, ensuring that the plunger rod can reciprocate smoothly and accurately during the rotation of the plunger barrel, thereby achieving effective generation and release of negative pressure.

[0012] Negative pressure channel design: A three-way connecting hole is provided in the guide ring, which is connected to the suction cup on the adsorption kit to ensure that the negative pressure can be transmitted to the suction cup in an orderly manner when the plunger rod reciprocates, thereby maintaining the continuous adsorption state of the plate.

[0013] Function of the adjustment seat: The adjustment seat is not only used to adjust the installation height of the first drive motor and the second drive motor, but also can adjust their output power and speed to meet the feeding requirements of plates of different specifications and thicknesses.

[0014] Piston ring configuration: The outer periphery of the plunger rod is sleeved with a piston ring that is interference fit with the piston cavity inside the rotary plug cylinder to enhance the sealing performance of the plunger rod in the piston cavity and improve the efficiency of negative pressure generation.

[0015] Through the above technical scheme and its preferred embodiment, the present invention provides a sheet feeding mechanism for furniture edge banding with a compact structure, diverse functions and a high degree of automation, which can effectively improve the production efficiency and product quality of the edge banding production line and meet the needs of modern furniture manufacturing for efficient, precise and intelligent edge banding processing.

[0016] The beneficial effects achieved by the present invention are: 1.

In the present invention, the servo controller sequentially programs and controls the servo motor, the first drive motor and the second drive motor, thereby realizing the automation of the entire process from plate loading, conveying, posture adjustment to final placement, reducing manual intervention, reducing the labor cost of the production line and improving efficiency.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0022] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0023] A sheet material feeding mechanism for furniture edge banding provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0024] Combination Figure 1-Figure 8 As shown, the present invention provides a board feeding mechanism for furniture edge banding, comprising: The conveying seat 100 has a plurality of servo motors 110 fixedly installed therein, and the output end of the servo motor 110 is transmission-connected to the omnidirectional wheel set 120 to form a Meccan mother wheel structure for realizing the omnidirectional movement of the feeding mechanism body; The support seat 200 is fixed to the top surface of the conveying seat 100 and is used to support and carry the plate; The transfer mechanism 300 includes a rotating drum 310, a shaft 320, a rotating plug drum 330 and a plurality of plunger rods 340 and other components, and is used for negative pressure adsorption, fixation and position adjustment of the plate during the conveying process.

[0025] In this embodiment, a servo controller is provided inside the conveying seat 100 for uniformly controlling the coordinated actions of the servo motors 110 and the first drive motor 312 and the second drive motor 313, thereby realizing fully automatic sheet material loading, conveying and posture adjustment.

[0026] The structure of the transfer mechanism 300: Rotating drum 310; like Figure 3As shown, the rotating drum 310 is rotatably sleeved on the inner side of the rotating drum 310 through the shaft 320, and a plurality of adsorption sets 311 are provided on the surface of the rotating drum 310, and a plurality of suction cups are provided on the adsorption sets 311. The adsorption sets 311 are preferably made of flexible materials such as silica gel to reduce friction damage to the surface of the plate.

[0027] Rotary plug cylinder 330 and plunger rod 340; like Figure 5 and Figure 6 As shown, the rotating plug cylinder 330 is fixedly sleeved on the surface of the shaft 320, and a plurality of piston cavities are opened inside. One end of the plunger rod 340 is slidably matched in the piston cavity, and the other end is connected to the negative pressure channel arranged on the surface of the rotating cylinder 310. The rotating plug cylinder 330 is driven by the first driving motor 312 to make a circular rotation, and the plunger rod 340 reciprocates in the piston cavity accordingly. When the plunger rod 340 moves to the top position of the piston cavity, negative pressure is generated inside the piston cavity, and the plate is adsorbed and fixed through the adsorption kit 311.

[0028] Adjustment seat 314 and independent drive motor; like Figure 3 and Figure 4 As shown, the first drive motor 312 and the second drive motor 313 are respectively arranged at the two ends of the rotating drum 310, and the installation angle and height thereof can be fine-tuned through the adjustment seat 314. The first drive motor 312 mainly drives the reciprocating motion of the rotating plug cylinder 330 and the plunger rod 340; the second drive motor 313 independently drives the rotating drum 310 to rotate, so as to adjust the relative position of the plate on the surface of the support seat 200. The two can work independently or in coordination in the control program to meet the conveying and edge sealing requirements under different working conditions.

[0029] Inclined seat 350 and V-shaped inclined structure; like Figure 5 , 8 As shown, the surface of the inclined seat 350 is arranged in a V shape, and a ring slide groove 351 is opened on the surface. A plurality of sliders 353 are arranged in the slide groove 351, and the sliders 353 are connected to the end of the plunger rod 340 through the sliding sleeve head 352. When the rotating plug cylinder 330 rotates with the shaft rod 320, the plunger rod 340 performs periodic telescopic movement along the inclined seat 350. Therefore, when the plunger rod 340 runs to the top position, the negative pressure value in the piston cavity reaches the maximum, and the strong adsorption of the plate is achieved.

[0030] The first drive motor 312 drives the shaft 320 and the rotary plug cylinder 330 to rotate, thereby realizing the circular motion of the plunger rod 340; the second drive motor 313 controls the self-rotational motion of the rotary drum 310 on the surface of the rotary plug cylinder 330 and the inclined seat 350, and then controls the rolling of the rotary drum 310 in steps to transport the plate on the surface of the support seat 200, thereby realizing loading and unloading and adjusting the relative position of the plate on the surface of the support seat 200; the circular motion control of the plunger rod 340 is realized by the first drive motor 312, so that the suction cup located at the top of the adsorption kit 311 generates negative pressure to have adsorption and gripping force on the plate.

[0031] During specific use, the operator first places the plate flat on the top surface of the support seat 200, and after starting the feeding mechanism, the servo motor 110 drives the omnidirectional wheel group 120 to move the conveying seat 100 to the designated loading or edge sealing position. Then, the first drive motor 312 drives the rotary plug cylinder 330 to rotate, and the plunger rod 340 forms a periodic negative pressure in the piston chamber, and the plate is tightly sucked by the suction cup on the adsorption kit 311; if the angle or alignment position of the plate on the support seat 200 needs to be adjusted, the second drive motor 313 is started to make the rotary cylinder 310 rotate, and the omnidirectional wheel group 120 moves in different directions according to the operation requirements, so as to realize multi-station or multi-angle handling and positioning. After the plate is transported to the edge sealing station, the feeding mechanism stops moving and maintains the negative pressure adsorption state, allowing the edge banding machine to seal the edge of the plate. After the edge sealing is completed, the plate is slid on the surface of the support seat 200 and detached from the surface of the support seat 200 to realize unloading by combining omnidirectional movement and rotation of the drum 310 .

[0032] The working principle and use process of the present invention: The board feeding mechanism for furniture edge banding of the present invention realizes automatic loading, conveying, posture adjustment and final positioning of the board through the coordinated work of multiple driving devices, which significantly improves the automation degree and production efficiency of the edge banding production line. Its main working principles can be divided into the following aspects: Omnidirectional mobile drive: An omnidirectional wheel set consisting of a plurality of servo motors 110 and a MecNam master wheel 120 is installed on the conveying seat 100. The servo motor 110 drives the MecNam master wheel 120 to rotate, so that the feeding mechanism body can achieve smooth movement and steering in any direction. This omnidirectional movement mode allows the feeding mechanism to flexibly adjust its position in a small or complex production environment to meet the needs of plate transfer between different workstations.

[0033] Plate adsorption and fixation: The transfer mechanism 300 includes a rotating drum 310, a rotating plug drum 330, and a plunger rod 340. Adsorption kits 311 are evenly distributed on the outer periphery of the rotating drum 310. Each adsorption kit 311 is equipped with a number of suction cups to achieve a stable grip of the plate through negative pressure adsorption. The first drive motor 312 drives the rotating plug drum 330 and the plunger rod 340 to perform circumferential reciprocating motion, generating alternating negative pressure adsorption and release effects, and ensuring the stability of the plate during the conveying process.

[0034] Multi-directional control and posture adjustment: The second drive motor 313 independently drives the rotating drum 310 to rotate, so as to adjust the relative position of the plate on the surface of the support base 200. Through the omnidirectional movement of the servo motor 110 and the omnidirectional wheel set 120, the feeding mechanism can adjust the position and posture in different directions, thereby realizing multi-directional control and precise conveying of the plate. This control method mainly relies on the omnidirectional movement of the feeding mechanism body to ensure the accurate positioning and stable conveying of the plate during the edge sealing process, rather than reversing the plate by the rotation of the rotating drum 310.

[0035] Automatic control system: The servo controller is integrated in the conveying base 100 and is responsible for orderly programming and controlling the servo motor 110, the first drive motor 312 and the second drive motor 313. Through the preset control program, the system can automatically complete the loading, conveying, posture adjustment and final positioning of the plate, reduce manual intervention, and improve production efficiency and stability.
