Description

Technical Field

[0001] This utility model relates to the field of profile processing and feeding technology, specifically to a feeding roller transmission and shifting mechanism. Background Technology

[0002] The profile feeding mechanism is a device used in the door and window manufacturing production line to transport door and window frame profiles to the processing equipment. It can replace manual handling and placement of profiles, reduce the intensity of manual labor, and is an important part of the door and window production line.

[0003] Currently, robotic arms are generally used to place profiles on the feeding mechanism. However, in addition to placing the profiles, the robotic arms also have to perform other actions. They may not be able to put the profiles back onto the feeding mechanism in time after the profiles have been transported on the feeding mechanism. The continuity of profile feeding is poor, which reduces processing efficiency. Furthermore, it is not convenient to automatically recycle unused profile tailings, which still requires manual operation, making it impractical.

[0004] Therefore, in order to address the above problems, a feeding roller drive switching mechanism is proposed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a feeding roller transmission and switching mechanism. This invention can improve the efficiency of profile feeding and facilitate the recycling and reuse of unused profile tailings, resulting in good economic efficiency.

Each feeding seat is connected to a feeding component through a lifting component. Shifting components are arranged on both sides along the length of the frame. The shifting components are equipped with a material preparation component and a positioning component. The material preparation component and the positioning component can enter the gap between the feeding seats through the drive of the shifting component. The positioning component is located on one side of the material preparation component, and the arrangement direction of the positioning component and the material preparation component is parallel to the length direction of the frame. The positioning component is slidably arranged on one side of the feeding seat, and the sliding direction is perpendicular to the length direction of the frame.

[0008] Preferably, the feeding assembly includes a feeding roller seat, a guide shaft is provided at the bottom of the feeding roller seat, the guide shaft is slidably disposed on the feeding roller seat and the sliding direction is perpendicular to the ground, and a feeding idler roller is rotatably disposed on the feeding roller seat, the axis of the feeding idler roller being horizontal and perpendicular to the length direction of the frame.

[0009] Preferably, side guard rollers are rotatably installed on the side of the feed roller seat away from the material preparation assembly, and the axis of the side guard rollers is perpendicular to the axis of the feed roller.

[0010] Preferably, the axis of the feed roller is horizontal to the ground and is inclined back and forth, with the end of the feed roller away from the side guard roller being close to the processing equipment, and the angle between the axis of the feed roller and the reference plane perpendicular to the length direction of the frame is 2°.

[0011] Preferably, the lifting assembly includes a lifting shaft that passes through and slides on the feed seat, with the axis of the lifting shaft parallel to the axis of the guide shaft. The top end of the lifting shaft is connected to a feed roller seat, and the bottom end of the lifting shaft is connected to a roller. The roller is movably mounted on a slider, which is slidably mounted at the bottom of the feed seat, with the sliding direction of the slider parallel to the length direction of the frame. A guide groove is formed on the slider along the length direction of the frame, and the guide groove is inclined vertically. The roller is movably mounted in the guide groove, and the roller can move along the guide groove through the sliding of the slider, thereby driving the lifting shaft to move up and down. Adjacent sliders are connected by a connecting rod, and one of the sliders at both ends is connected to the output end of the lifting power component, which is mounted on the frame.

[0012] Preferably, the shifting assembly includes a left drive shaft and a right drive shaft, which are respectively located on both sides of the frame and their axes are parallel to each other. Several corresponding pulleys are coaxially arranged on both the left and right drive shafts. A synchronous belt is provided between the pulleys on adjacent left and right drive shafts. A shifting power component is connected to the left or right drive shaft and is located on the frame to drive the left or right drive shaft to rotate.

[0013] Preferably, the material preparation assembly includes a lifting cylinder, which is mounted on a synchronous belt and can move with the synchronous belt. The axis of the output end of the lifting cylinder is parallel to the axis of the lifting shaft. A material preparation roller seat is provided at the output end of the lifting cylinder.

A moving pressure roller is mounted on the moving end of the rodless cylinder. The axis of the moving pressure roller is parallel to the axis of the static pressure roller. The heights of both the static pressure roller and the moving pressure roller are higher than the height of the material preparation roller, and are used to clamp the profile placed on the positioning material preparation roller.

[0015] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages:

[0016] 1. This utility model features a material preparation component that can temporarily hold profiles to be conveyed. The robotic arm only needs to place the profiles on the material preparation component during the time interval between other actions. After the profiles on the feeding component are fed, the material preparation component moves to the upper side of the feeding component under the drive of the switching component and places the profiles on the material preparation component on the feeding component. Then it returns to the initial position to receive the next profile to be conveyed. When there are unused profile tails on the feeding component, the material preparation component can also lift the profile tails on the feeding component and have them picked up by the robotic arm and moved to the tail storage position. It has good practicality.

[0017] 2. This utility model, by setting a positioning component, can clamp and position the profile to prevent it from falling off when the material preparation component moves the profile. When retrieving the profile tail material from the feeding component, the tail material is positioned on one side of the material preparation component, which facilitates accurate gripping by the robot arm and improves processing efficiency and economy.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4 As shown, this utility model provides a technical solution:

[0026] The feeding roller drive shifting mechanism is set at the feeding end of the processing equipment, which is generally a sawing, drilling, tapping, or other equipment used to process profiles. The feeding roller drive shifting mechanism includes a frame 1, on which several spaced feeding seats 2 are set along its length. Each feeding seat 2 is connected to a feeding component 4 via a lifting component 3. Shifting components 5 are set on both sides along the length of the frame 1. The shifting components 5 are equipped with a material preparation component 6 and a positioning component 7. The material preparation component 6 and the positioning component 7 can be moved by the shifting components 5 and enter the gaps between the feeding seats 2. The positioning component 7 is located on one side of the material preparation component 6, and the arrangement direction of the positioning component 7 and the material preparation component 6 is parallel to the length direction of the frame 1. The positioning component 7 is slidably set on one side of the feeding seat 2 to improve stability during movement, and the sliding direction is perpendicular to the length direction of the frame 1.

[0027] In an optional embodiment, the feeding assembly 4 includes a feeding roller seat 41, which is U-shaped. A guide shaft 42 is provided at the bottom of the feeding roller seat 41. The guide shaft 42 is slidably mounted on the feeding seat 2 through a bushing, and the sliding direction is perpendicular to the ground. A feeding idler roller 43 is rotatably mounted on the feeding roller seat 41. The feeding idler roller 43 is made of rubber or nylon, and the axis of the feeding idler roller 43 is horizontal to the ground and perpendicular to the length direction of the frame 1. Preferably, one end of the feeding idler roller 43 is connected to the output end of a rotating power component to drive the feeding idler roller 43 to rotate in order to convey the profile. The rotating power component is a motor.

[0028] In an optional embodiment, side guard rollers 44 are rotatably provided on the side of the feed roller seat 41 away from the material preparation assembly 6. The axis of the side guard rollers 44 is perpendicular to the axis of the feed roller 43 to prevent the profile from falling off when it is conveyed on the feed roller 43.

[0029] In one optional embodiment, the axis of the feed roller 43 is horizontal to the ground and is inclined back and forth. The end of the feed roller 43 away from the side stop roller 44 is close to the processing equipment. The angle between the axis of the feed roller 43 and the reference plane perpendicular to the length direction of the frame 1 is 2°, so that the profile can be pressed against the side stop roller 44 when it is conveyed on the feed roller 43, and the profile is prevented from falling off the side of the feed roller 43 away from the side stop roller 44 during the conveying process. In another embodiment, a pusher is provided at the end of the frame 1 away from the processing equipment. The pusher can be an electric push rod. The output end of the pusher can contact the profile on the feed roller 43 and give the profile an initial velocity, so that the profile enters the processing position of the processing equipment under the action of inertia.

[0030] In an optional embodiment, the lifting assembly 3 includes a lifting shaft 31, which passes through and slidably mounts on the feed seat 2. The axis of the lifting shaft 31 is parallel to the axis of the guide shaft 42. The top end of the lifting shaft 31 is threadedly connected to the feed roller seat 41 and is limited by a nut to facilitate adjustment of the height of the feed roller seat 41. The bottom end of the lifting shaft 31 is connected to a roller 32, which is movably mounted on a slider 33. The slider 33 is slidably mounted on the bottom of the feed seat 2, and the sliding direction of the slider 33 is parallel to the length direction of the frame 1. A guide is provided on the slider 33 along the length direction of the frame 1. The guide groove 34 is inclined vertically, and the roller 32 is movably disposed in the guide groove 34. The sliding of the slider 33 enables the roller 32 to move along the guide groove 34, thereby causing the roller 32 to drive the lifting shaft 31 to move up and down. Adjacent sliders 33 are connected by a connecting rod 35. One of the sliders 33 at both ends of the frame 1 is connected to the output end of the lifting power component 36. The lifting power component 36 is a cylinder, which is disposed on the frame 1 so that the lifting shaft 31 moves up and down at the same time, thereby driving the feeding roller 43 to move up and down, which facilitates the replacement of the profile position with the material preparation assembly 6.

[0031] In an optional embodiment, the shifting assembly 5 includes a left drive shaft 51 and a right drive shaft 52, which are located on opposite sides of the frame 1. The axes of the left drive shaft 51 and the right drive shaft 52 are parallel to the length direction of the frame 1. Several corresponding pulleys 53 are coaxially arranged on both the left drive shaft 51 and the right drive shaft 52. A synchronous belt 54 is arranged between the pulleys 53 on adjacent left drive shaft 51 and right drive shaft 52. A material preparation assembly 6 and a positioning assembly 7 are arranged on the synchronous belt 54. A shifting power component 55 is connected to the left drive shaft 51 or the right drive shaft 52. The shifting power component 55 is a motor, which is arranged on the frame 1 and is used to drive the left drive shaft 51 or the right drive shaft 52 to rotate, thereby driving the material preparation assembly 6 and the positioning assembly 7 to move left and right.

[0032] In an optional embodiment, the material preparation assembly 6 includes a lifting cylinder 61, which is mounted on a synchronous belt 54 and can move with the synchronous belt 54. The axis of the output end of the lifting cylinder 61 is parallel to the axis of the lifting shaft 31. A material preparation roller seat 62 is provided at the output end of the lifting cylinder 61. A material preparation roller 63 is rotatably mounted on the material preparation roller seat 62. The axis of the material preparation roller 63 is parallel to the ground and perpendicular to the length direction of the frame 1, and is used to contact the profile.

[0033] In an optional embodiment, the positioning component 7 includes a positioning frame 71, which is mounted on the synchronous belt 54 and can move with the synchronous belt 54. The positioning frame 71 is slidably mounted on one side of the feed seat 2, with the sliding direction parallel to the moving direction of the lifting cylinder 61 with the synchronous belt 54. This serves to assist in supporting the positioning frame 71 and prevent it from sinking due to gravity. A static pressure roller 72 is rotatably mounted on one end of the positioning frame 71 near the feed roller 43. The axis of the static pressure roller 72 is parallel to the axis of the lifting shaft 31. A rodless cylinder 73 is mounted on the positioning frame 71, with the sliding direction of the moving end of the rodless cylinder 73 parallel to the sliding direction of the positioning frame 71. A moving pressure roller 74 is mounted on the moving end of the rodless cylinder 73, with the axis of the moving pressure roller 74 parallel to the axis of the static pressure roller 72. The heights of both the static pressure roller 72 and the moving pressure roller 74 are higher than the height of the preparation roller 63. The static pressure roller 72 and the moving pressure roller 74 are used to clamp and position the profile placed on the preparation roller 63, facilitating accurate clamping by the robot arm.

[0034] In an optional embodiment, a control component is also included, which is controlled by a commercially available CNC system and connected to each power component. This component controls the start and stop of each power component and records the initial coordinates of the profile clamped and positioned on the material preparation roller 63 in the initial state of the material preparation component 6 into the CNC system, so as to control the robot arm to accurately clamp and pick up the profile.

[0035] Working principle: First, the robotic arm places the profile onto the preparation roller 63. Then, the rodless cylinder 73 is activated, clamping the profile using the static pressure roller 72 and the moving pressure roller 74. Next, the output end of the lifting cylinder 61 extends, positioning the preparation roller 63 at a high position, while simultaneously controlling the feeding roller 43 to a low position. Then, the shifting power component 55 is activated, causing the preparation assembly 6 and the positioning assembly 7 to enter the gap between the feeding seat 2, i.e., between the feeding assemblies 4, avoiding interference with the movement of the feeding assembly 4. Then, the clamping between the moving pressure roller 74 and the static pressure roller 72 is released, and the output end of the lifting cylinder 61 retracts, positioning the preparation roller 63 at a low position. Simultaneously, the feeding roller 43 is raised to contact the profile and lift it from the preparation roller 63, ensuring the height of the moving pressure roller 74 and the static pressure roller 72 is lower than the bottom of the profile. The switching power component 55 rotates in the reverse direction, moving the material preparation component 6 and the positioning component 7 back to their original positions to receive the next profile to be conveyed. The profile on the feeding roller 43 is conveyed and processed. When the tail material of the profile on the feeding roller 43 needs to be removed, the profile on the material preparation roller 63 is removed first. Then, the moving pressure roller 74 and the stationary pressure roller 72 are moved away from each other, the material preparation roller 63 is in a low position and the feeding roller 43 is in a high position. The material preparation component 6 and the positioning component 7 are moved into the gap between the feeding seat 2. The feeding roller 43 is lowered and the material preparation roller 63 is raised, so that the material preparation roller 63 lifts the tail material of the profile on the feeding roller 43. Then, the moving pressure roller 74 and the stationary pressure roller 72 clamp the tail material of the profile. The material preparation component 6 and the positioning component 7 are moved back to their original positions. Then, the tail material of the profile is grabbed by the robot and moved to the temporary storage area for use.
