Description

Technical Field

[0001] This utility model relates to the field of edge banding machine feeding technology, and more specifically, to a feeding edge roller table. Background Technology

[0002] In panel furniture production lines, roller conveyors are widely used for automated conveying of panels. For edge banding operations, randomly positioned panels need to be stably guided and pressed against one side of the conveyor during feeding (i.e., edge contact) to ensure edge banding quality. Existing conveyor edge contact mechanisms often suffer from the following problems: unstable edge contact effect, affecting subsequent edge banding accuracy; rigid mechanisms are prone to scratching the panel surface; and the lack of effective anti-collision mechanisms allows collisions between panels or between panels and the mechanism, leading to production interruptions and equipment damage. Therefore, we propose an improved feeding edge contact roller table. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0018] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of this utility model can be combined with each other.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] like Figures 1-3 As shown, this embodiment proposes a feeding edge roller table, including: a roller table frame, and an edge inclined roller 1, a conveying straight roller 5, a conveying guide 2, a feeding pressure roller 3, and a side pushing mechanism 4 disposed on the roller table frame; the edge inclined roller 1 and the conveying guide 2 cooperate with each other to guide the plate to move toward the conveying guide 2; the feeding pressure roller 3 is disposed above the conveying straight roller 5 to press the plate in the vertical direction; the side pushing mechanism 4 is disposed on the other side of the conveying path to push the plate toward the conveying guide 2 and make it close to the conveyor.

[0021] The surface of the inclined roller 1 is covered with a rubber layer.

[0022] The feed roller 3 includes multiple sets of roller assemblies and a telescopic drive device for driving the roller assemblies to rise and fall; the roller assembly includes at least two positioning rollers and a linkage rod connecting the positioning rollers; the telescopic drive device includes a cylinder, a movable plate connected to the linkage rod, and a fixed plate fixed on the roller table frame.

[0023] The side-pushing mechanism 4 includes a servo motor, a linkage shaft driven by the servo motor, at least two sets of pusher assemblies mounted on the linkage shaft, and a mounting bracket for mounting the servo motor and the linkage shaft; the pusher assembly includes a frame and sliding rollers mounted on the frame.

[0024] The frame and mounting bracket are connected by a slide bar and a slider, and the clamping force between the sliding roller and the plate is adjustable.

[0025] The side push mechanism 4 is configured to receive plate size information and control the servo motor to drive the pusher assembly to move, so as to adjust the opening distance between it and the conveyor ruler 2. The opening distance is the plate size plus a safety margin; the safety margin is at least 30mm.

[0026] It also includes a sensor, which is located in the area between the inclined roller 1 and the conveying straight roller 5, to detect the position of the plate and trigger the action of the side push mechanism 4.

[0027] The roller table is connected to the robot's automatic loading and unloading system and return line, and can receive and process information such as the size, quantity and edge banding type of the panels.

[0028] Specifically: The main body is a rigid roller table frame. Multiple inclined rollers 1 and conveying straight rollers 5 are arranged on the roller table frame through a bearing array and are driven to rotate by a drive device. A conveying guide 2 is fixedly installed on one side of the roller table frame along the conveying direction.

[0029] The feed roller 3 is mounted above the conveyor roller 5 via a bracket. It comprises two sets of roller assemblies, each consisting of a linkage rod and two positioning rollers. The linkage rod is connected at both ends to a movable plate driven by a cylinder. The cylinder body is fixed to a fixed plate, which in turn is fixed to the roller table frame. Cylinder movement raises and lowers the entire roller assembly, thereby pressing or releasing the plate.

[0030] The side-pushing mechanism 4 is located on the other side of the conveying path, opposite the conveying guide 2. It includes a servo motor, a linkage shaft driven by the servo motor, two pusher assemblies, and a robust mounting bracket. Each pusher assembly includes a frame and multiple sliding rollers mounted on the frame. The frame is connected to two sliding rods fixed to the mounting bracket via sliders and can move along the sliding rods under the drive of the servo motor, thereby changing the opening distance between it and the conveying guide 2. The contact pressure between the sliding rollers and the plate can be adjusted by an adjusting mechanism (such as a spring).

[0031] A photoelectric sensor is installed in the area between the inclined roller 1 and the straight conveyor roller 5 to detect whether the plate has been conveyed to that position.

[0032] Specific examples: The sheet metal is fed into this roller table by the upstream equipment. The inclined roller 1 guides it to the conveyor ruler 2, completing the initial edge-fitting. The sheet metal continues to move forward, triggering the sensor, and the signal is transmitted to the control system. The control system calculates the target position of the side-pushing mechanism 4 (sheet metal size + 30mm, safety distance = 1230mm) based on the preset sheet metal size (e.g., 1200mm) and controls the servo motor to drive the pusher assembly to move to that position. At the same time, the cylinder of the feeding pressure roller 3 actuates, pressing down the positioning roller to help stabilize the sheet metal. Driven by the conveying straight roller 5, the sheet metal continues to move forward and is gently pushed against the conveyor ruler 2 by the sliding roller of the side-pushing mechanism 4, finally entering the edge-sealing machine stably. For sheets metal that need to be sealed on all four sides, under the control of the main control system, after sealing two sides, the sheet metal flows back to this roller table. The side-pushing mechanism 4 will readjust the opening distance according to the sheet metal size of the next process and monitor the position in real time to ensure that it operates within the safe range. If an abnormality occurs, an alarm will sound and the machine will stop.

[0033] In use, to ensure the edge-banded boards are not scratched when moving along the edge, the edge-banding inclined roller 1 is rubber-coated; the feeding roller table is used in conjunction with a robot for automatic loading and unloading and a return line. Materials are received from pallets, with uniform dimensions and known quantities. During automatic production, the dimensions, quantity, and number of sides to be banded (two sides, four sides) of the board need to be input; when the feeding edge-banding roller table is running, the side-push mechanism 4 moves according to the input dimensions (e.g., 1200mm) under servo control, automatically adjusting the distance between the mounting frame and the sliding rollers, increasing the safety distance by 30mm to prevent the edge-banded boards from colliding with the side-push sliding rollers or with each other. The opening distance is 1230mm; the boards are conveyed along the edge to the feeding pressure roller 3 mechanism via the edge-banding inclined roller 1 and the conveyor guide 2. A sensor is added between the edge-banding inclined roller 1 and the conveyor straight roller 5. When the board is detected flowing out, the side push mechanism 4 is activated to press the board against the edge banding machine track. The side push mechanism 4 is equipped with sliding rollers, and the side push clamping force is adjustable. When the board is sealed on two sides (two long sides or two short sides): the corresponding size is input, and the edge banding is automatically returned to the two sides. When the board is sealed on four sides (first the two short sides, then the two long sides): the corresponding size is input for edge banding production. After the two sides are completed, the main control gives a side push adjustment signal to adjust to the safe distance for the next production and monitors the side push position in real time. When the opening and closing distance is greater than the board size but less than the safe distance, production can continue. When the opening and closing distance is less than the board size, the line stops conveying and an alarm is triggered to prevent board collision. When the opening and closing distance is greater than the safe distance size of the board, the line stops conveying and an alarm is triggered. The side push cannot push the product, affecting the board's edge and the edge banding.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
