Description

Technical Field

[0001] The invention belongs to the technical field of processing equipment, and in particular relates to an automatic feeding system for sawing aluminum profiles. Background Art

[0002] During the aluminum profile processing, the entire long strip of aluminum profile needs to be cut into small sections of the same length. On the aluminum profile sawing production line, an automatic loading system is usually used to continuously and automatically load the aluminum profile to improve production efficiency.

[0003] The existing aluminum profile feeding system is equipped with two sets of power drives, a lifting cylinder and a translation drive device (such as a lead screw, a servo electric cylinder, etc.), which move the feeding rack in the height direction and the horizontal direction respectively, so as to first lift the aluminum profile, then move the aluminum profile forward to place it on the conveying mechanism, and then the conveying mechanism intermittently transports the aluminum profile to the sawing mechanism for cutting. The feeding system with this structure has high equipment cost and bloated structure. The lifting cylinder and the translation drive device have high power consumption, which increases the operating cost and is not conducive to energy saving and consumption reduction. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic feeding system for sawing aluminum profiles, so as to solve the problems of high equipment cost and bloated structure of the feeding system for aluminum profiles.

[0005] The present invention provides the following technical solutions:

[0006] An automatic feeding system for sawing aluminum profiles, comprising a temporary storage rack, a feeding mechanism, a feeding mechanism and a sawing mechanism;

[0007] The temporary storage rack can store multiple aluminum profiles at intervals;

[0008] The loading mechanism is used to load the aluminum profiles from the temporary storage rack to the feeding mechanism. The loading mechanism includes a driving device, a turntable and a loading rack. The output shaft of the driving device is connected to the turntable arranged along the Z axis. A transmission column is eccentrically arranged on the turntable along the Y axis. The loading rack is hinged on the transmission column. The initial height of the loading rack is lower than the height of the temporary storage rack. When the turntable rotates, the loading rack can reciprocate in the coordinate plane of the X axis and the Z axis, lift up the aluminum profiles on the temporary storage rack and transport them to the feeding mechanism.

[0009] The feeding mechanism comprises a plurality of conveying rollers and a conveying motor, and the conveying motor can drive the conveying rollers to rotate and convey the aluminum profile to the sawing mechanism.

[0010] Preferably, the feeding mechanism also includes a balancing assembly, which includes a vertical frame, a first guide block, a sliding beam, a second guide block and a support column; the vertical frame is fixed on the ground, the first guide block is fixed on the side wall of the vertical frame, a first guide groove is provided in the first guide block along the X-axis, and the sliding beam can be horizontally slidably installed in the first guide groove; the second guide block is fixed on the sliding beam, a second guide hole is provided in the second guide block along the Z-axis, the support column can be vertically slidably installed in the second guide hole, and the top of the support column is fixedly connected to the feeding frame.

[0011] Preferably, two first guide blocks are installed on the stand, and the left and right sides of the sliding beam are respectively embedded in the first guide grooves of the two first guide blocks; the second guide block is fixed to the middle of the sliding beam.

[0012] Preferably, the support column is fixed to the middle part of the loading rack.

[0013] Preferably, the support column is cylindrical, the second guide block is a cylindrical pipe, and the diameter of the second guide hole matches the diameter of the support column.

[0014] Furthermore, a plurality of first positioning blocks and second positioning blocks for positioning the aluminum profiles are respectively installed on the temporary storage rack and the loading rack, and the spacing between two adjacent first positioning blocks is the same as the spacing between two adjacent second positioning blocks.

[0015] Preferably, the spacing between two adjacent first positioning blocks is equal to the linear distance that the transmission column moves when the loading rack is in the process of lifting up the aluminum profile and putting down the aluminum profile.

[0016] Preferably, a third positioning groove for positioning the aluminum profile is circumferentially provided on the conveying roller, and the X-axial distance between the third positioning groove and the first positioning block closest thereto is equal to the spacing between two adjacent first positioning blocks.

[0017] Preferably, the third positioning groove of the conveying roller is flush with the height of the first positioning block of the temporary storage rack.

[0018] Preferably, the loading racks of the two groups of loading mechanisms can respectively support the front and rear ends of the aluminum profile.

[0019] The beneficial effects of the present invention are:

[0020] The feeding mechanism of the present invention comprises a driving device, a turntable and a feeding rack. The driving device can drive the turntable to rotate. A transmission column is eccentrically fixed on the turntable. The feeding rack is hinged on the transmission column. When the turntable rotates, the feeding rack follows the transmission column and moves in the vertical plane simultaneously along the up and down and front and back directions. Since the initial height of the feeding rack is lower than the height of the temporary storage rack, the feeding rack can lift the aluminum profile on the temporary storage rack under the action of the transmission column, and then transport it forward along the X-axis to the conveying roller, and then the conveying motor and the conveying roller convey the aluminum profile to the sawing mechanism to be cut into the required length.

[0021] The feeding mechanism of the present invention can realize continuous feeding by driving the turntable to rotate by a group of driving devices. There is no need to configure two groups of power driving devices, namely a lifting cylinder and a translation driving device (such as a screw, a servo electric cylinder, etc.), thereby reducing the number of driving devices, having a compact structure, and reducing equipment costs and operating costs.

[0022] The balancing component of the feeding mechanism can make the moving feeding rack always stably in a horizontal state without tipping over, thus improving the feeding stability. Since the bottom of the feeding rack is supported by the support column, the lower side of the support column is installed in the second guide block and can move up and down along the second guide block, the feeding rack will not tip over under the common limit of the transmission column and the second guide block; the second guide block is fixed on the sliding beam, and when the feeding rack moves, under the transmission of the support column and the second guide block, the sliding beam slides horizontally along the first guide block, and the sliding beam ensures that the second guide block and the support column always remain in a vertical state, thereby reliably supporting the feeding rack.

[0023] The first positioning block, the second positioning block and the third positioning groove on the temporary storage rack, the loading rack and the conveying roller of the present invention can position the aluminum profile more stably and improve the loading accuracy. The first positioning block, the second positioning block and the third positioning groove are arranged at corresponding intervals, so that when the loading rack moves with the rotating turntable, the aluminum profile on the temporary storage rack closest to the conveying roller can be accurately fed into the third positioning groove of the conveying roller, and other aluminum profiles are just moved forward to the previous positioning block, so that the loading accuracy is higher.

[0031] The invention provides an automatic feeding system for sawing aluminum profiles, which is installed on an aluminum profile sawing production line and is used for feeding the aluminum profiles to a conveying roller at a specified rhythm, and then the conveying roller feeds the aluminum profiles to a sawing mechanism, and then the sawing mechanism cuts the aluminum profiles into required lengths.

[0032] like Figure 1 and Figure 2 As shown, the present invention includes a temporary storage rack 10 , a loading mechanism 20 , a feeding mechanism 30 and a sawing mechanism 40 .

[0033] like Figure 3 As shown, a plurality of aluminum profiles 50 can be stored in parallel at intervals on the temporary storage rack 10; a plurality of first positioning blocks 11 are fixedly mounted on the temporary storage rack 10, and a positioning groove that is shaped like the aluminum profile 50 is provided on the first positioning block 11, so that the aluminum profile 50 can be placed in the positioning groove for positioning to prevent the aluminum profile from shaking.

[0034] like Figures 1 to 3 As shown, the feeding mechanism 30 includes a plurality of conveying rollers 31 and a conveying motor 32. The conveying motor 32 is horizontally mounted on the frame 60. The conveying motor 32 may be an optional stepping motor. The conveying rollers 31 are mounted on the output shaft of the conveying motor 32. The conveying motor 32 can drive the conveying rollers 31 to rotate and convey the aluminum profile 50 to the sawing mechanism 40.

[0035] The loading mechanism 20 can transport the aluminum profile 50 from the temporary storage rack 10 to the feeding mechanism 30. Figure 2 , Figure 4 and Figure 5The feeding mechanism 20 includes a driving device 21, a turntable 22 and a feeding rack 23. The driving device 21 is installed on the frame. The driving device 21 can be a stepper motor with a reducer. The output shaft of the driving device 21 is connected to the turntable 22 arranged along the Z axis. A transmission column 221 is eccentrically fixedly installed on the turntable 22 along the Y axis. The feeding rack 23 is horizontally arranged along the X axis. The middle part of the feeding rack 23 is hinged on the transmission column 221. Therefore, when the turntable 22 rotates, the feeding rack 23 can reciprocate in the coordinate plane of the X axis and the Z axis (that is, it moves up and down and forward and backward at the same time). Please refer to Figure 2 , the initial height of the loading rack 23 is lower than the height of the temporary storage rack 10, that is, in the initial state, the aluminum profile 50 is supported by the temporary storage rack 10. When the aluminum profile 50 needs to be transported to the conveying roller 31, the driving device 21 drives the turntable 22 to rotate, so that the loading rack 23 reciprocates in the XZ coordinate plane (that is, along the up and down and front and back directions at the same time), please refer to Figure 4 and Figure 5 The loading rack first moves forward and upward to lift up all the aluminum profiles 50 on the temporary storage rack 10, and then moves forward and downward to drop the frontmost aluminum profile onto the conveying roller 31. The other aluminum profiles also move forward by one action stroke, and then the loading rack 23 continues to move backward and downward to reset to the initial position.

[0036] Please refer to Figure 2 , Figure 4 and Figure 5The feeding mechanism 20 also includes a balancing component, which can improve the stability of the feeding frame 23 and prevent the feeding frame 23 from tilting or falling. The balancing component includes a stand 24, a first guide block 25, a sliding beam 26, a second guide block 27 and a support column 28. The stand 24 is fixed to the ground by bolts, and two first guide blocks 25 are installed on the side walls of the stand 24 by screws. The two first guide blocks 25 are located on the same horizontal line. A first guide groove 251 matching the cross-sectional shape of the sliding beam 26 is provided in the first guide block 25 along the X-axis. The left and right sides of the sliding beam 26 are respectively inserted into the two first guide grooves 251, so that the sliding beam 26 can slide horizontally along the first guide grooves 251. The second guide block 27 is welded and fixed to the middle of the sliding beam 26. A second guide hole 271 matching the diameter of the support column 28 is provided in the second guide block 27 along the Z axis. The lower side of the support column 28 is inserted into the second guide hole 271. The support column 28 can slide up and down along the second guide hole 271. The top of the support column 28 is welded to the middle of the loading rack 23. The first guide block 25 can guide the forward and backward movement of the loading rack 23, and the second guide block 27 can guide the up and down movement of the loading rack 23, so that the loading rack 23 always maintains balance and stability without tilting or tipping. The specific balancing process is: when the turntable 22 rotates, since the bottom of the loading rack 23 is supported by the support column 28, the lower side of the support column 28 is installed in the second guide block 27 and can move up and down along the second guide block 27, so the loading rack 23 will not tip under the common limit of the transmission column 221 and the second guide block 27. Since the loading rack 23 moves forward and backward while moving up and down, the thrust applied to the support column 28 by the loading rack 23 due to the forward and backward movement is transmitted to the sliding beam 26 by the second guide block 27, so that the sliding beam 26 slides horizontally along the first guide block 25. The balancing component makes the entire loading process flexible, ensuring that the second guide block 27 and the support column 28 are always in a vertical state, thereby reliably supporting the loading rack 23.

[0037] The support column 28 can be cylindrical, square or other polygonal. Preferably, the support column is cylindrical. The second guide block 27 is a cylindrical pipe. The diameter of the second guide hole 271 matches the diameter of the support column, which facilitates flexible installation of the second guide block and the support column.

[0038] Please refer to Figure 4, a plurality of second positioning blocks 231 for positioning the aluminum profiles are installed on the loading rack 23, and the spacing between two adjacent first positioning blocks 11 on the temporary storage rack 10 is the same as the spacing between two adjacent second positioning blocks 231 on the loading rack. The spacing between two adjacent first positioning blocks 11 is equal to the linear distance that the transmission column 221 moves during the process of the loading rack 23 lifting the aluminum profile to putting it down. Therefore, each time the loading rack 23 moves, it can accurately move the aluminum profile 50 forward by one movement stroke and drop it onto the previous first positioning block, and the loading action is more accurate.

[0039] Please refer to Figure 1 and Figure 2 , the temporary storage rack 10, the conveying roller 31 and the loading rack 23 are all staggered in the Y-axis direction, so the loading rack 23 will not interfere with the conveying roller 31 when moving forward and backward. The conveying roller 31 is provided with a third positioning groove 311 for positioning the aluminum profile along the circumferential direction, and the X-axial distance between the third positioning groove 311 and the first positioning block 11 closest to it is equal to the spacing between two adjacent first positioning blocks 11. Similarly, each time the loading rack 23 moves, it can accurately move the aluminum profile at the front side forward by one movement stroke and drop it onto the third positioning groove 311 of the conveying roller 31. The height of the third positioning groove 311 of the conveyor roller is flush with the first positioning block 11 of the temporary storage rack 10. Therefore, before the aluminum profile falls, the conveyor roller 31 will not interfere with the transportation action of the loading rack 23. When the loading rack 23 puts down the aluminum profile, the frontmost second positioning block 231 on the loading rack 23 overlaps with the projection of the third positioning groove 311 of the conveyor roller on the Y-axis, so that the aluminum profile 50 falls accurately on the third positioning groove 311 of the conveyor roller.

[0040] The system is equipped with two sets of feeding mechanisms 20 , and the feeding frames 23 of the two sets of feeding mechanisms 20 can respectively support the front and rear ends of the aluminum profile 50 .

[0041] The working process of the present invention is:

[0042] Place multiple aluminum profiles 50 on the first positioning blocks 11 of the temporary storage rack in sequence. At this time, the height of the loading rack 23 of the loading mechanism 20 is lower than the height of the temporary storage rack 10. Then start the stepper motor of the loading mechanism 20 to drive the turntable 22 to rotate. The loading rack 23 moves in the coordinate plane of the X-axis and the Z-axis under the action of the transmission column 221. When the height of the second positioning block 231 of the loading rack 23 is slightly higher than the height of the first positioning block 11, the loading rack 23 lifts the aluminum profile 50 and continues to move forward until the front aluminum profile falls into the third positioning groove 311 of the conveying roller, and the other aluminum profiles automatically move forward for a stroke, and then the loading rack 23 is reset to the initial position. Start the conveying motor 32 and drive the conveying roller 31 to convey the aluminum profile 50 to the direction of the sawing mechanism 40. The sawing mechanism 40 cuts the aluminum profile into small sections according to the required length. While cutting, other aluminum profiles can continue to be loaded onto the temporary storage rack 10. When the sawing mechanism 40 completes cutting of one group of aluminum profiles, the above process is repeated to load the next group of aluminum profiles onto the conveying roller.

Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
