Description

Technical Field

[0001] The present application relates to the field of sheet feeding, and in particular to a horizontal positioning and correction device for sheet feeding. Background Art

[0002] During the transmission of sheets, the position may be inclined due to the placement. If the starting position is not aligned, the sheet will output an incorrect route during the entire transmission.

[0003] To correct the horizontal position of the sheet during the sheet transportation process, a Chinese patent document with the publication number CN103738039A discloses a synchronous embossing feeding positioning and correction device, which includes synchronous belts. There are two mutually parallel synchronous belts installed on a synchronous belt frame. The synchronous belts are in transmission connection with a motor, and the motor is arranged at one end of the synchronous belt frame; a positioning and correction mechanism is fixed below the synchronous belt frame.

[0004] Regarding the above technical solution, the inventor believes that when using the above device, it is necessary to manually detect whether the sheet is in the correct position. When the position of the sheet is incorrect, the synchronous embossing is adjusted to move in the horizontal and vertical directions through a three-layer positioning and correction mechanism to reach the required precise position. However, the method of manually detecting the position has a relatively high labor intensity, and it is difficult to control the detection accuracy, which is not conducive to the subsequent sheet processing and production. Summary of the Utility Model

[0005] In order to reduce the labor intensity of detecting the position of the sheet, improve the detection accuracy of the sheet position, and further ensure the correction accuracy of the sheet position, the present application provides a horizontal positioning and correction device for sheet feeding.

[0006] A horizontal positioning and correction device for sheet feeding provided by the present application adopts the following technical solution:

[0007] A horizontal positioning and correction device for sheet feeding includes a positioning and correction mechanism. The positioning and correction mechanism is a three-layer structure of an upper frame, a middle frame, and a lower frame from top to bottom. A synchronous belt is provided at the upper end of the upper frame, and position sensors are provided at both ends of the upper frame and are arranged upward.

[0008] By adopting the above technical solution, the distance between the two position sensors is pre-set to be slightly larger than the length of the transported plate. When in use, the synchronous belt conveys the plate. When the plate is conveyed by the synchronous belt and there is a time point when both position sensors do not display a signal, the detected plate is in the correct position. If there is no time point when both position sensors do not display a signal from the start of the movement of the plate to the time when the plate passes through the two position sensors, the position of the detected plate is deviated, and a positioning correction mechanism is required to correct the position of the plate. The present application uses two position sensors to replace traditional manual position detection of the plate, which reduces labor intensity and is conducive to improving the detection accuracy of the plate position, thereby ensuring the correction accuracy of the plate position.

[0009] Optionally, the upper frame is provided with an adjustment mechanism for adjusting the distance between the two position sensors.

[0010] By adopting the above technical solution, the distance between the two position sensors can be adjusted through the adjustment mechanism to adapt to plates of different lengths, thereby improving the applicability of the device.

[0011] Optionally, the adjustment mechanism includes two linear modules arranged on the upper frame, and the sliders of the linear modules are connected to the position sensors in a one-to-one correspondence, so as to drive the corresponding position sensors to move along the length direction of the upper frame.

[0012] By adopting the above technical solution, each position sensor can be moved linearly through the corresponding linear module, thereby achieving the purpose of adjusting the distance between the two position sensors.

[0013] Optionally, the lower frame is provided with a first servo motor and a first slideway, and the first servo motor is drivingly connected to the middle frame;

[0014] The middle frame is provided with a first slider at the bottom and a second slideway at the top, wherein the first slider is installed in coordination with the first slideway, and the middle frame is provided with a second servo motor, which is transmission-connected to the upper frame;

[0015] A second sliding block is provided at the bottom of the upper frame, and the second sliding block is installed in cooperation with the second slideway;

[0016] The spatial positions of the first slideway and the second slideway are perpendicular to each other.

[0017] By adopting the above technical solution, during use, the middle layer frame is driven by the first servo motor, and the first slider at the bottom of the middle layer frame moves along the first slideway; the upper layer frame is driven by the second servo motor, and the second slider at the bottom of the upper layer frame moves along the second slideway. Since the spatial positions of the first slideway and the second slideway are perpendicular to each other, that is, the relative movement directions of the upper layer frame and the middle layer frame are perpendicular to each other. By adjusting the movement of the synchronous belt in the perpendicular directions, the precise adjustment of the position of the sheet material can be achieved.

[0018] Optionally, the second slider and the upper layer frame are connected by a pin.

[0019] By adopting the above technical solution, the upper layer frame can rotate relative to the middle layer frame within the plane where it is located, thereby further improving the calibration accuracy of the position of the sheet material.

[0020] Optionally, a bracket is provided on the middle layer frame, a ball is provided at the top of the bracket, and the top of the ball abuts against the upper layer frame.

[0021] By adopting the above technical solution, on the one hand, the upper layer frame is supported by the ball, and on the other hand, when the upper layer frame and the middle layer frame have relative movement, the movement resistance and wear therebetween are reduced.

[0022] Optionally, at least two synchronous belts are arranged in parallel, driving pulleys for driving the synchronous belts to transmit are provided on the inner sides of all the synchronous belts, all the driving pulleys are coaxially connected in series by a transmission shaft, and a driving mechanism for driving the transmission shaft to rotate is provided on the upper layer frame.

[0023] By adopting the above technical solution, the sheet material is transported by at least two synchronous belts to ensure the stable loading and transportation of the sheet material; and all the synchronous belts are driven by the same transmission shaft, and the driving mechanism can drive the transmission shaft to rotate, thereby realizing the synchronous operation of each synchronous belt and ensuring that the running speeds of each synchronous belt are consistent, further improving the transmission stability of the device.

[0024] Optionally, the driving mechanism includes a reduction motor provided on the upper layer frame and a first synchronous pulley provided at the output end of the reduction motor, a second synchronous pulley is coaxially fixed on the transmission shaft, and the first synchronous pulley is connected to the second synchronous pulley by a transmission belt.

[0025] By adopting the above technical solution, when the reduction motor is started, it drives the first synchronous pulley to rotate, and drives the second synchronous pulley to rotate through the transmission effect of the transmission belt, thereby achieving the purpose of driving the transmission shaft to rotate.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. By setting two position sensors, the distance between the two position sensors is preset to be slightly greater than the length of the plate to be transported before use. During use, the synchronous belt conveys the plate. When there is a time point during the synchronous belt conveyance of the plate where neither of the two position sensors shows a signal, the detected plate is in the correct position. If there is no time point during the period from the start of the movement of the plate to passing through the two position sensors where neither of the two position sensors shows a signal, the position of the detected plate is deviated, and a positioning and correction mechanism is required to correct the position of the plate. In this application, two position sensors are used to replace the traditional manual position detection of the plate, reducing the labor intensity, facilitating the improvement of the detection accuracy of the plate position, and further ensuring the correction accuracy of the plate position.

[0028] 2. By setting an adjustment mechanism, it is convenient to adjust the distance between the two position sensors at any time to adapt to plates of different lengths and improve the applicability of the device.

[0029] 3. The plate is transported by at least two synchronous belts to ensure stable loading and transportation of the plate; and all the synchronous belts are driven by the same transmission shaft. The driving mechanism can drive the transmission shaft to rotate, thereby realizing the synchronous operation of each synchronous belt and ensuring that the running speeds of each synchronous belt are the same, further improving the transmission stability of the device.

[0037] The following is combined with the attached Figures 1-6 to further elaborate on this application in detail.

[0038] Embodiment:

[0039] The embodiment of this application discloses a horizontal positioning and calibration device for sheet material feeding. Refer to Figure 1 , a horizontal positioning and calibration device for sheet material feeding, including a positioning and calibration mechanism 1. The positioning and calibration mechanism 1 is a three-layer structure of an upper frame 11, a middle frame 12, and a lower frame 13 from top to bottom. A synchronous belt 2 is installed at the upper end of the upper frame 11, and at least two synchronous belts 2 are arranged in parallel. In this embodiment, three synchronous belts 2 are arranged in parallel to jointly support and transport the sheet material, ensuring the stability of sheet material transmission.

[0040] Refer to Figure 2 , driving pulleys 21 for driving the synchronous belt 2 to drive are arranged on the inner sides of all the synchronous belts 2. All the driving pulleys 21 are coaxially connected and fixed through a transmission shaft 22, and a driving mechanism 3 is arranged on the upper frame 11. The driving mechanism 3 includes a reducing motor 31 and a first synchronous pulley 32, and the reducing motor 31 is installed on the upper frame 11. The first synchronous pulley 32 is coaxially fixed to the output end of the reducing motor 31. A second synchronous pulley 221 is coaxially fixed on the transmission shaft 22, and the first synchronous pulley 32 is in transmission connection with the second synchronous pulley 221 through a transmission belt 321. When the reducing motor 31 is started, it drives the first synchronous pulley 32 to rotate, and drives the second synchronous pulley 221 to rotate through the transmission of the transmission belt 321. The rotation of the second synchronous pulley 221 drives the transmission shaft 22 to rotate, and the rotation of the transmission shaft 22 drives all the driving pulleys 21 to rotate, thereby ensuring that each synchronous belt 2 rotates synchronously and at the same speed, and further improving the transmission stability of the device.

[0041] Refer to Figures 1-2, upwardly disposed position sensors 4 are provided at both ends of the upper frame 11, and an adjustment mechanism 5 for adjusting the distance between the two position sensors 4 is also provided on the upper frame 11. The adjustment mechanism 5 includes two linear modules 51 fixed on the upper frame 11, and the sliders of the linear modules 51 are connected to the position sensors 4 in a one-to-one correspondence, and are used to drive the corresponding position sensors 4 to move along the length direction of the upper frame 11. In this embodiment, the position sensor 4 is a photoelectric sensor.

[0042] When in use, first adjust the distance between the two position sensors 4 according to the length of the current batch of plates, so that the distance is slightly larger than the length of the current batch of plates. Each sensor is moved and adjusted by the linear module 51 to adapt to plates of different length specifications. When in use, the synchronous belt 2 conveys the plate. When the two position sensors 4 show no signal at the time point during the conveyance of the synchronous belt 2, the detected plate is in the correct position. If there is no time point from the start of the movement of the plate to the passing of the two position sensors 4 when the two position sensors 4 show no signal, the position of the detected plate is deviated, and the positioning and correction mechanism 1 is required to correct the position of the plate. Using two position sensors 4 to replace traditional manual position detection of the plate reduces labor intensity, helps to improve the detection accuracy of the plate position, and thus ensures the correction accuracy of the plate position.

[0044] When in use, the middle frame 12 is driven by the first servo motor 131, and the first slider 121 at the bottom of the middle frame 12 moves along the first slide 132; the upper frame 11 is driven by the second servo motor 123, and the second slider 111 at the bottom of the upper frame 11 moves along the second slide 122. Since the spatial positions of the first slide 132 and the second slide 122 are perpendicular to each other, that is, the relative movement directions of the upper frame 11 and the middle frame 12 are perpendicular to each other. By adjusting the movement of the synchronous belt 2 in the perpendicular directions, the precise adjustment of the plate position can be achieved.

[0045] Reference Figures 4-5, the second slider 111 and the upper frame 11 are connected by a shaft pin 112. In this way, the upper frame 11 can rotate relative to the middle frame 12 within the plane where it is located, thereby further improving the calibration accuracy of the position of the plate.

On the one hand, the upper frame 11 is supported by the ball 1241, and on the other hand, when the upper frame 11 and the middle frame 12 move relatively, the movement resistance and wear therebetween are reduced, ensuring the smooth use of the device and being beneficial to extending the service life of the device.
