Description

Technical Field

[0001] This utility model relates to the field of profile feeding, and in particular to a general profile feeding device. Background Technology

[0002] A reinforced mullion in doors and windows is a special structural design that specifically refers to adding a vertical support rod to large glass windows or floor-to-ceiling windows. It is usually located in the center of the glass. The purpose of this design is to increase the structural stability and strength of the window to withstand the weight of the glass and external pressure, thereby improving the window's safety and durability. (See attached image.) Figure 1 As shown, the reinforced mullion consists of upper and lower sections, with a crossbeam protruding from both sections.

[0003] In existing profile feeding devices, the profile clamping assembly includes an upper pressure plate driven by a cylinder, a rear positioning roller and a front positioning roller arranged opposite each other. The rear positioning roller is higher than the front positioning roller. The front positioning roller is equipped with a cylinder and can move closer to and further away from the rear positioning roller. When clamping ordinary profiles (with a rectangular cross-section), the upper pressure plate presses against the top of the profile, and the front positioning roller presses against the lower side of the profile and cooperates with the rear positioning roller to clamp the profile.

[0004] When a feeding device with the above clamping components is used for feeding reinforced mullions, due to the special structure of the reinforced mullions and the fact that the clamps are all driven by cylinders, when the reinforced mullions are clamped, the side of the crossbeam abuts against the rear positioning roller. As the front positioning roller moves closer to the side of the lower section of the reinforced mullion, it is constrained by the crossbeam and the rear positioning roller cannot contact the lower section of the reinforced mullion. Furthermore, the cylinder of the front positioning roller cannot stop at a certain position in the middle. This causes the front positioning roller to move closer to the rear positioning plate, causing the reinforced mullion to tilt. As a result, the existing feeding device cannot clamp the reinforced mullion normally and cannot feed the material, which also results in the low versatility of the existing profile feeding device. Utility Model Content

[0005] To address the technical problem that existing profile feeding devices cannot simultaneously meet the feeding requirements of reinforced mullions, this invention provides a universal profile feeding device that can meet the feeding needs of both ordinary profiles and reinforced mullions, demonstrating a high level of versatility.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a general-purpose profile feeding device, including a support frame, and further including: multiple support plates, which are arranged along the length direction of the support frame; a rear positioning roller, which is vertically arranged at one end of the support plate; a front positioning roller, which is connected to a positioning drive component and is movably arranged on the support plate, and is arranged opposite to the rear positioning roller; an anti-tilt roller, which is movably arranged on the support plate, and the movement direction of the anti-tilt roller is parallel to the movement direction of the front positioning roller; an anti-tilt drive assembly, which connects multiple anti-tilt rollers to the same anti-tilt drive assembly, which includes multiple sets of rotatably connected drive arms and transmission arms, which are rotatably connected to the corresponding anti-tilt rollers, and the multiple drive arms are connected to the same anti-tilt rotating shaft, which is rotatably arranged on the support frame, and is connected to a drive motor, which is arranged on the support frame.

[0007] This invention, by setting multiple anti-tilt rollers driven by the same drive motor, can control the anti-tilt rollers to remain stationary or move to a set displacement according to the structural characteristics of the profile. This ensures normal feeding of ordinary profiles and prevents tilting when the feeder is clamped by the front positioning roller. This makes the feeding device also meet the needs of feeding the feeder with reinforced feeder, thus improving the versatility of the feeding device.

[0008] Furthermore, the positioning drive component is a cylinder, and the positioning drive component is horizontally disposed at the end of the support plate.

[0009] Furthermore, the anti-tilt shaft is rotatably mounted through multiple mounting plates, the mounting plates are connected to corresponding connecting plates on the support frame, the mounting plates are provided with multiple mounting holes, and the connecting plates are provided with multiple horizontal adjustment holes and vertical adjustment holes, all of which are straight groove holes.

[0010] This utility model, by setting multiple mounting holes, multiple horizontal adjustment holes and vertical adjustment holes, can adjust the anti-tilt shaft, ensure the installation accuracy of the anti-tilt shaft, and avoid skewing affecting the feeding accuracy.

[0011] Furthermore, the drive motor is a servo motor.

[0012] Furthermore, it also includes a transverse conveying assembly, which comprises multiple transverse conveyor belts arranged along the length of the support frame.

[0013] Furthermore, the support frame is provided with a lifting beam, which is movably mounted on the support frame. The lifting beam is provided with a support plate, which can drive the support plate to rise to a height higher than the transverse conveyor belt. The support frame is provided with a feeding clamp, which moves along the length of the support frame.

[0014] This invention features a lifting beam that automatically lifts and lowers the profiles from the transverse conveying assembly to the support plate for longitudinal conveying, thus improving the automation level of the device.

[0015] Furthermore, the lifting beam is connected to at least two lifting cylinders, which are mounted on the support frame. The lifting beam is also rotatably connected to at least two swing rods, which are connected to corresponding swing arms. Multiple swing arms are sleeved on the same balance shaft, which is rotatably mounted on the support frame and is parallel to the anti-tilt shaft.

[0016] This invention, by setting up a balance shaft, a swing arm, and a swing rod, can ensure that the lifting beam remains horizontal when rising, and avoids the tilting caused by the asynchronous movement of multiple lifting cylinders, which would affect the feeding accuracy.

[0017] Furthermore, it also includes a clamping cylinder, which is vertically mounted on the lifting beam. The piston rod of the clamping cylinder is connected to a mounting plate. A rotating cylinder is mounted on the mounting plate. The piston rod of the rotating cylinder is rotatably connected to one side of the rotating plate. The rotating plate is rotatably mounted on the mounting plate. The rotating plate is connected to an upper pressure plate via a connecting rod.

[0018] This invention enhances the clamping effect of the device on the profile by rotatably setting the upper pressure plate, and the rotatable setting of the upper pressure plate does not affect the lateral feeding of the lateral conveying component.

[0019] Furthermore, the clamping cylinder is mounted on the support plate, and a displacement sensor is provided between the support plate and the mounting plate.

[0020] This invention uses a position sensor to detect the displacement of the upper pressure plate, thereby determining the profile height and facilitating the detection of incorrect materials.

[0021] Furthermore, the displacement sensor includes a grating ruler and an electromagnetic reading head, the grating ruler being vertically mounted on the support plate and the electromagnetic reading head being mounted on the mounting plate.

[0022] As can be seen from the above technical solutions, this utility model has the following advantages:

[0023] This utility model provides a universal profile feeding device. By setting multiple anti-tilt rollers driven by the same drive motor, the device can control the anti-tilt rollers to remain stationary or move to a set displacement according to the structural characteristics of the profile. This ensures normal feeding of ordinary profiles and prevents tilting when the central eaves are clamped by the front positioning roller. This makes the feeding device also meet the needs of strengthening the central eaves feeding, thus improving the versatility of the feeding device. By setting multiple mounting holes, multiple horizontal adjustment holes, and multiple vertical adjustment holes, the anti-tilt rotating shaft can be adjusted to ensure the installation accuracy of the anti-tilt rotating shaft and avoid tilting from affecting the feeding accuracy. By setting up a lifting beam, the profiles can be automatically lifted and lowered to transfer from the transverse conveying assembly to the support plate for longitudinal conveying, thus improving the automation level of the device. By setting up a balance shaft, swing arm, and swing rod, the lifting beam can be kept in a horizontal state during ascent, avoiding misalignment of multiple lifting cylinders that could cause tilting and affect feeding accuracy. The upper pressure plate, which can be rotatably set up, enhances the device's clamping effect on the profiles, and its rotatability does not affect the transverse feeding of the transverse conveying assembly. The position sensor can detect the displacement of the upper pressure plate, thereby determining the profile height and facilitating the detection of incorrect materials. Attached Figure Description

[0033] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent. Specific Implementation Method 1

[0035] like Figures 2 to 4 As shown in the figure, this specific embodiment provides a general-purpose profile feeding device, including a support frame 2, multiple support plates 8, a rear positioning roller 7, a front positioning roller 6, an anti-tilting roller 5, and an anti-tilting drive assembly; the multiple support plates 8 are arranged along the length direction of the support frame 2, and two guide rails are arranged parallel to each other on one side of the support plate 8; the rear positioning roller 7 is vertically and rotatably mounted on one end of the support plate 8 through a central axis; the front positioning roller 6 is connected to a positioning drive assembly, and the front positioning roller 6 is movably mounted on the support plate 8, with the front positioning roller 6 and the rear positioning roller 7 arranged opposite to each other; the anti-tilting roller 5... The anti-tilt roller 5 is movably mounted on the support plate 8, and its moving direction is parallel to that of the front positioning roller 6. Multiple anti-tilt rollers 5 are connected to the same anti-tilt drive assembly, which includes multiple sets of rotatably connected drive arms 11 and transmission arms 12. The transmission arms 12 are rotatably connected to the corresponding anti-tilt roller 5. Multiple drive arms 11 are connected to the same anti-tilt rotating shaft 19, which is rotatably mounted on the support frame 2. The anti-tilt rotating shaft 19 is connected to a drive motor 18, which is mounted on the support frame 2.

[0036] This specific embodiment, by setting multiple anti-tilting rollers 5 driven by the same drive motor 18, can control the anti-tilting rollers 5 to remain stationary or move to a set displacement according to the structural characteristics of the profile. This ensures normal feeding of ordinary profiles and prevents tilting when the central support is clamped by the front positioning roller 6, making this feeding device also meet the needs of the central support feeding and improving the versatility of the feeding device.

[0037] like Figure 2 As shown, preferably, in this specific embodiment, the front positioning roller 6 is mounted on slider one via its central axis, and slider one is mounted on a corresponding guide rail. The anti-tilt roller 5 is mounted on slider two via its central axis, and slider two is mounted on a corresponding guide rail. Slider two is located on one side of slider one. When anti-tilt roller 5 is not needed for clamping, slider two is located at the end of support plate 8. Slider two is rotatably connected to one end of transmission arm 12 via a pin, and the other end of transmission arm 12 is rotatably connected to one end of drive arm 11 via a pin. The other end of drive arm 11 is rotatably connected to the anti-tilt roller 5. The tilting shaft 19 is clearance-fitted, and the number of drive arms 11 and transmission arms 12 is the same as the number of anti-tilt rollers 5. In this specific embodiment, the anti-tilt shaft 19 includes multiple sub-shafts connected by couplings. The power of the drive motor 18 is transmitted from the anti-tilt shaft 19 to multiple drive arms 11. The drive arms 11 swing at a corresponding angle, and the drive arms 11 drive the transmission arms 12 to rotate. The transmission arms 12 drive the slider 2 to move a set distance. The anti-tilt roller 5 moves a corresponding distance from the rear positioning roller 7 to the front positioning roller 6. This distance is the distance D between the side of the lower section of the reinforcing echelon and the end of the crossbeam.

[0038] In this specific embodiment, the positioning drive component 14 is a cylinder, and the positioning drive component 14 is horizontally arranged at the end of the support plate 8.

[0039] like Figure 3 As shown, due to the relatively long length of the anti-tilt shaft 19, in order to ensure the installation accuracy of the anti-tilt shaft 19, especially its levelness, and to avoid its skewness affecting the movement accuracy of the anti-tilt roller 5, or even causing the anti-tilt roller 5 to move poorly, in this specific embodiment, the anti-tilt shaft 19 is rotatably mounted through multiple mounting plates. The mounting plates are connected to the corresponding connecting plates 13 on the support frame 2. The mounting plates are provided with multiple mounting holes, and the connecting plates 13 are provided with multiple horizontal adjustment holes and vertical adjustment holes. The horizontal adjustment holes and the vertical adjustment holes are all straight groove holes. By measuring the levelness of the anti-tilt roller 5, the relative positions of the mounting holes, horizontal adjustment holes and vertical adjustment holes involved in the installation can be adjusted to ensure the installation levelness.

[0040] To ensure that the anti-tilting roller 5 moves the corresponding distance accurately, in this specific embodiment, the drive motor 18 is a servo motor.

[0041] In this specific embodiment, a support roller is horizontally arranged on the support plate 8, and the support roller is rotatably arranged on the support plate 8 through its own central axis. Specific Implementation Method Two

[0043] like Figure 5 As shown, this specific embodiment provides a general-purpose profile feeding device, which is basically the same in structure as the first specific embodiment, except that: this specific embodiment also includes a transverse conveying assembly 4, which includes multiple transverse conveyor belts. These multiple transverse conveyor belts are arranged along the length of the support frame 2, and are driven by the same motor through a single drive shaft, ensuring the synchronous conveying of the multiple transverse conveyor belts; furthermore, a lifting beam 3 is provided on the support frame 2, which is vertically and flexibly mounted on the support frame 2. Specifically, the lifting beam 3 is connected to at least two lifting cylinders 9. The lifting cylinder 9 is mounted on the support frame 2, and the support plate 8 is mounted on the lifting beam 3. The lifting beam 3 can drive the support plate 8 to rise to a height higher than the transverse conveyor belt. The support frame 2 is equipped with a feeding clamp 1, which moves along the length of the support frame 2. Through the cooperation of the transverse conveying component 4, the lifting beam 3, and the feeding clamp 1, after the profile material moves to the set position, the support plate 8 is raised to transfer the profile material on the transverse conveying component 4 to the support plate 8, realizing the automatic change of profile material material from transverse conveying to longitudinal conveying, and improving the automation level of the feeding of this device.

[0044] In this specific embodiment, the feeding clamp 1 is used to clamp the end of the profile material, and then moves along the length direction of the support frame 2 under the drive of the feeding motor and the gear rack mechanism to push the profile material for feeding; the feeding clamp 1 is prior art, and its structure will not be described in detail in this article.

[0045] like Figure 6As shown, due to the relatively long lifting beam 3 and the time difference in the actions of multiple lifting cylinders 9, the lifting beam 3 may not maintain a horizontal state during lifting, affecting the feeding accuracy and clamping reliability. To avoid this problem, in this specific embodiment, the lifting beam 3 is rotatably connected to at least two swing rods 25 via pins. The end of each swing rod 25 is connected to the end of a corresponding swing arm 10 via another pin. Multiple swing arms 10 are mounted on the same balance shaft 17, which can drive the balance shaft 17 to rotate. The balance shaft 17 is rotatable via bearings and mounting bases. The balance shaft 17 is set on the support frame 2, and the anti-tilt shaft 19 is set parallel to it. With this setting, when one of the lifting cylinders 9 is activated, it drives the lifting beam 3 to rise, which in turn drives the swing rod 25 to move and rotate, which drives the swing arm 10 to rotate. The swing arm 10 drives the balance shaft 17 to rotate at a certain angle, which in turn drives the other swing arms 10 that cannot rotate synchronously with the same amplitude angle to rotate. This pulls and compensates for the lifting cylinders 9 that are not raised synchronously, ensuring that the lifting beam 3 is in a horizontal state after being raised, and avoiding the tilting caused by the asynchronous operation of multiple lifting cylinders 9, which would affect the feeding accuracy.

[0046] like Figure 7 As shown, to ensure the compression of the profile material, this specific embodiment also includes a compression cylinder 16. The compression cylinder 16 is vertically mounted on the lifting beam 3. The piston rod of the compression cylinder 16 is connected to a mounting plate. A rotating cylinder 20 is mounted on the mounting plate. The piston rod of the rotating cylinder 20 is rotatably connected to a protruding arm on one side of the rotating plate 21 via a pin. The rotating plate 21 is rotatably mounted on the mounting plate. The rotating plate 21 is connected to an upper pressure plate 15 via a connecting rod. When the upper pressure plate 15 is pressed, the rotating cylinder 20 first extends to drive the rotating plate 21 to rotate by a set angle, so that the upper pressure plate 15 rotates 90° perpendicular to the length direction of the profile. Then the compression cylinder 16 retracts, driving the upper pressure plate 15 to descend and press tightly against the upper surface of the profile material.

[0047] like Figure 7 As shown, since there may be material mixing issues with the profile raw materials, in order to detect and alert to incorrect materials in a timely manner during feeding, in this specific embodiment, the clamping cylinder 16 is mounted on the support plate, and a displacement sensor is provided between the support plate and the mounting plate. The displacement sensor can detect the moving distance of the upper pressure plate 15, and then calculate the height of the profile raw material. The displacement sensor can be a pull rope displacement sensor. In this specific embodiment, a grating ruler 24 sensor is used. The grating ruler 24 sensor includes a grating ruler 24 and an electromagnetic reading head 22. The grating ruler 24 is vertically mounted on the support plate, and the electromagnetic reading head 22 is mounted on the mounting plate.

[0048] It is understandable that the number of upper pressure plates 15 can be less than the number of rear positioning rollers 7, depending on the length setting of the feeding profile, but the number should not be less than two.

[0049] The working process of this general-purpose profile feeding device is as follows:

[0050] When the material is being fed into the central support, the transverse conveying component 4 moves laterally a set distance to move the profile material to the upper part of the support plate 8, and the rear end face of the crossbeam is in contact with the rear positioning roller 7; the lifting beam 3 rises, and the support rod supports the profile material; the drive motor 18 rotates, and the anti-tilting roller 5 moves a corresponding distance to contact the lower rear inner part of the profile; the front positioning roller 6 moves to abut against the lower front vertical surface, and the anti-tilting roller 5 achieves the anti-tipping function; the upper pressing plate rotates 90° and falls down, pressing against the upper surface of the profile material, while the displacement sensor transmits the displacement information to the system controller to determine whether there is a material error; after the profile material height meets the requirements, the feeding clamp 1 clamps the end and pushes the profile material to move longitudinally;

[0051] When feeding ordinary profiles, the transverse conveying component 4 moves laterally a set distance to move the profile material to the upper part of the support plate 8, and the rear end face of the crossbeam is in contact with the rear positioning roller 7; the lifting beam 3 rises, the support rod supports the profile material, and the anti-tilt roller 5 is located at the end of the support plate 8 and does not participate in clamping; the front positioning roller 6 moves to abut against the front facade; the upper pressing plate rotates 90° and falls down to press against the upper surface of the profile material, while the displacement sensor transmits the displacement information to the system controller to determine whether there is a material error; after the profile material height meets the requirements, the feeding fixture 1 clamps the end and pushes the profile material to move longitudinally.

[0052] As can be seen from the above specific embodiments, this utility model has the following beneficial effects:

[0053] 1. By setting multiple anti-tilting rollers 5 driven by the same drive motor 18, the anti-tilting rollers 5 can be controlled to remain stationary or move to a set displacement according to the structural characteristics of the profile. This ensures normal feeding of ordinary profiles and prevents tilting when the middle rib is clamped by the front positioning roller 6, so that this feeding device also meets the needs of strengthening the middle rib feeding and improves the versatility of the feeding device.

[0054] 2. By setting multiple mounting holes, multiple horizontal adjustment holes and vertical adjustment holes, the anti-tilt shaft 19 can be adjusted to ensure the installation accuracy of the anti-tilt shaft 19 and avoid skewing affecting the feeding accuracy;

[0055] 3. By setting up the lifting beam 3, the profiles can be automatically lifted and transferred from the transverse conveying component 4 to the support plate 8 for longitudinal conveying, thereby improving the automation level of this device;

[0056] 4. By setting the balance shaft 17, swing arm 10 and swing rod 25, it can be ensured that the lifting beam 3 rises in a horizontal state, and avoid the multiple lifting cylinders 9 moving asynchronously, causing it to tilt and affecting the feeding accuracy.

[0057] 5. The upper pressure plate is rotatably mounted to enhance the clamping effect of this device on the profile, and the rotatable upper pressure plate 15 does not affect the transverse feeding of the transverse conveying assembly 4;

[0058] 6. The position sensor can detect the displacement of the upper pressure plate 15, thereby determining the profile height and facilitating the detection of incorrect materials.

[0059] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
