Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
In the present invention, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," "engaged," "hinged," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
The two ends in the longitudinal direction of the swing direction defining unit/upper support/lower support body are defined as opposite ends of the swing direction defining unit/upper support/lower support body, and the two ends in the width direction of the swing direction defining unit/upper support/lower support body are defined as opposite sides of the swing direction defining unit/upper support/lower support body.
As in the background art, the swing center of the existing deviation correcting mechanism is generally set according to the tension of the material to be conveyed. Because the point position of the swing center is constant or the moving track of the point position of the swing center is constant, the existing correction mechanism can only be suitable for the correction requirement of single materials, cannot be suitable for correcting various materials with different tension, and has poor universality.
In order to improve the above-described problems, referring to fig. 1, 2, 3, 4, 5 and 6, there is provided a deviation rectifying mechanism including a lower support 110, an upper support 120, a guide roller 130 and two swing direction defining units 140. The lower supporter 110 serves to support the upper supporter 120, the guide roller 130, and the two swing direction defining units 140. The upper support 120 is disposed above the lower support 110, and the opposite ends thereof are capable of swinging to a predetermined extent. The axes of the guide rollers 130 are parallel to the longitudinal direction of the upper support 120, and are mounted on the top surface of the upper support 120, and opposite ends can swing with the opposite ends of the upper support 120 to a preset degree. The guide rollers 130 are used to convey the material. One of the swing direction defining units 140 is mounted to one ends of the upper and lower holders 120 and 110 for limiting the swing direction of one end of the upper holder 120. Another swing direction limiting unit 140 is installed at the other ends of the upper and lower supports 120 and 110 for limiting the swing direction of the other ends of the upper support 120. The angles between the body length direction of the two swing direction limiting units 140 and the body length direction of the lower support base are respectively adjustable.
As shown in fig. 6, the body length direction of one of the swing direction defining units 140 is selected as a first reference line, and a perpendicular to the first reference line, which is assumed to be a first perpendicular line, is made with the mechanical connection point of the swing direction defining unit 140 and the upper mount 120 as a first base point. A vertical line of the second reference line, which is assumed to be a second vertical line, is drawn by selecting the body length direction of the other swing direction defining unit 140 as the second reference line and the mechanical connection point of the swing direction defining unit 140 and the upper mount 120 as the second base point. The intersection point of the first vertical line and the second vertical line is the point where the swing center is located. It should be noted that, as both ends of the upper support 120 and the guide roller 130 swing, the positions of the first base point and the second base point change, and thus, the point where the center of swing is located also changes. By adjusting the included angle between the body length direction of the two swing direction limiting units 140 and the body length direction of the lower support base, the movement track of the point where the swing center is located can be adjusted. In the process of swinging the upper support 120, the positions of the first base point and the second base point change, and the point position of the swinging center after the change can be determined according to the positions of the first base point and the second base point after the change.
The working process and principle of the deviation correcting mechanism are as follows:
firstly, according to the tension characteristics of the materials to be conveyed, the included angles between the body length directions of the two swing direction limiting units 140 and the body length direction of the lower supporting seat are respectively adjusted, and the included angles are-30 degrees to +30 degrees so as to adjust the moving track of the point position of the swing center, so that the deviation correcting mechanism is suitable for correcting materials with various different tensions, and the universality of the deviation correcting mechanism is improved. Then, the two ends of the upper support 120 can swing to a preset degree, and further the two ends of the guide roller 130 are driven to swing to a preset degree, and in the process of swinging the two ends of the upper support 120 and the guide roller 130, the mechanical connection points of the two ends of the swing direction limiting unit 140 and the upper support 120 serve as supporting points for restraining the swing directions of the two ends of the upper support 120 and the guide roller 130. Because the included angle between the body length direction of the two swing direction limiting units 140 and the body length direction of the lower supporting seat can be-30 degrees to +30 degrees, no matter the material is conveyed forward or reversely, the material advancing direction can be rectified, and the problem that the existing rectifying mechanism can only rectify the material conveyed in the constant direction is solved. Meanwhile, by adjusting the included angles between the body length direction of the two swing direction limiting units 140 and the body length direction of the lower supporting seat, the deviation rectifying mechanism is quickly applicable to rectifying the currently conveyed materials, so that the deviation rectifying efficiency is improved, and the deviation rectifying efficiency is higher.
Specifically, in the illustrated example, as shown in fig. 3, 4, and 5, each swing direction defining unit 140 includes a guide box 141 and a slider 142. A guide bar 1411 is provided inside the guide box 141, and the body length direction of the guide bar 1411 is the same as the body length direction of the guide box 141. The bottom surface of the guide box 141 is rotatably connected with the lower support 110 through a rotation shaft and a bearing, so that the guide box 141 can rotate, and further, an included angle between the body length direction of the swing direction limiting unit 140 and the body length direction of the lower support is adjusted. The sliding block 142 is slidably mounted on the guide rod 1411, and the top surface of the sliding block 142 is rotatably connected with the upper support 120 through a rotating shaft and a bearing, so that the sliding block 142 can rotate, and the sliding block 142 is prevented from being blocked in the guide box 141. Scale marks 111 are respectively arranged at two opposite ends of the top surface of the lower support 110, and the scale marks 111 at two ends are respectively-30 degrees to +30 degrees. Correspondingly, the mutually facing sides of the guide boxes 141 of the two pivoting-direction limiting units 140 are each provided with a pointer 1142 adapted to the graduation marks 111. The indicator 1142 cooperates with the scale mark 111 to effectively improve the adjustment accuracy in adjusting the longitudinal direction of the guide box 141, thereby achieving the purpose of quantization adjustment.
The point positions of the swing centers corresponding to the scale marks 111-30 degrees to +30 degrees are different in moving track. Gradually increasing from 0 deg. to +30 deg. or gradually decreasing from 0 deg. to-30 deg., the corresponding swing radius gradually decreases. Assuming that the indicator 1142 points at 0 to +30°, it is used to correct the material when the material is conveyed in the forward direction, and if the indicator 1142 points at-30 to 0 °, it is used to correct the material when the material is conveyed in the reverse direction. When the indicator 1142 points to 0 °, the correction mechanism is a direct-push correction mechanism.
Specifically, in the illustrated example, the deviation correcting mechanism further includes two rotary drivers 150 and one linear driver 160. Two linear drivers 160 are respectively installed at opposite ends of the bottom of the lower supporter 110. The output shafts of the two rotary drivers 150 are fixedly connected to the bottom surfaces of the guide boxes 141 of the two swing direction defining units 140 in one-to-one correspondence for driving the corresponding guide boxes 141 to rotate. The non-driving end of the linear driver 160 is mounted on the top surface of the middle portion of the lower supporter 110, and the driving end is mounted on the bottom surface of the upper supporter 120 for driving the opposite ends of the upper supporter 120 and the guide roller 130 to swing. Therefore, the degree of automation is effectively improved, and the movement track of the swing center can be quickly adjusted according to the requirement.
Preferably, the rotary drive 150 is a servo motor or a drive motor or the like.
Preferably, the linear actuator 160 is a pneumatic cylinder, an electric push rod, or the like.
Preferably, the lower support 110 has a frame structure, a lower support beam is provided at the middle part, and lower support plates are provided at opposite ends, respectively. The upper support 120 has a frame structure, an upper support beam is arranged in the middle, and upper support plates are respectively arranged at two opposite ends. The upper support 120 and the lower support 110 of the frame structure are beneficial to the light weight design of the deviation rectifying mechanism. The non-driving end of the linear driver 160 is rotatably coupled to the top surface of the lower support beam through a rotation shaft. The driving end of the linear driver 160 is rotatably connected to the bottom surface of the upper support beam through a rotation shaft. The bottom surface of the guide box 141 is rotatably coupled to the lower support plate of the lower supporter 110 through a rotation shaft and a bearing. The top surface of the slider 142 is rotatably coupled to the upper support plate of the upper supporter 120 through a rotation shaft and a bearing,
to meet the forward and reverse deviation rectifying demands, first and second detection sensors 170 and 180 are installed at opposite sides of one end of the lower support 110, respectively. The first detection sensor 170 is used to detect the edge of the material being conveyed. The second detection sensor 180 is used to detect the edge of the reversely conveyed material. It should be noted that, the first detection sensor 170 and the second detection sensor 180 are both infrared sensors, and specific detection principles and detection processes are related art and are not described herein. The controller is electrically connected to the first detection sensor 170, the second detection sensor 180, each linear actuator 160, and each rotary actuator 150, respectively. According to the material conveying direction, the first detection sensor 170 or the second detection sensor 180 can detect the edge position of the conveyed material and feed back the edge position to the controller, and the controller controls the two rotary drivers 150 to operate by combining the tension characteristic of the material to be conveyed and external actual factors, so that the body length direction of the guide box 141 of the two swing direction limiting units 140 forms a certain included angle with the body length direction of the lower support base. Then, the controller controls the linear driver 160 to work, so that the correction efficiency is high.
Specifically, in the illustrated example, the guide rollers 130 are two, and are respectively installed at opposite sides of the upper supporter 120. The deviation rectifying process is more smoothly performed than the single guide roller 130.
The deviation correcting mechanism can realize two working modes:
automatic operation mode: when the edge position offset of the material is too large or too small, the effect of correcting the running track is achieved through the motor of the rotary driver 150. The control logic ensures that the correction always ensures a high-efficiency working mode and ensures the correction stability.
Manual adjustment mode: because the physical properties of the materials are different and are subjected to multiple influences such as external factors, the maximum angles at which the edge positions of the materials can deviate are different, and the deviation rectifying running track can be manually adjusted.
The invention also provides a working method of the deviation correcting mechanism, which comprises the following steps: s1, according to the tension of the materials, the two rotary drivers 150 respectively adjust included angles formed between the body length direction of the two swing direction limiting units 140 and the body length direction of the lower supporting seat. S2, the linear driver 160 enables the opposite ends of the upper support 120 to swing to a preset degree, and further drives the opposite ends of the guide roller 130 to swing to a preset degree. Therefore, the deviation rectifying mechanism is suitable for rectifying materials with various different tensions, and the universality of the deviation rectifying mechanism is improved. Because the included angle between the body length direction of the two swing direction limiting units 140 and the body length direction of the lower supporting seat can be-30 degrees to +30 degrees, no matter the material is conveyed forward or reversely, the material advancing direction can be rectified, and the problem that the existing rectifying mechanism can only rectify the material conveyed in the constant direction is solved. Meanwhile, by adjusting the included angles between the body length direction of the two swing direction limiting units 140 and the body length direction of the lower supporting seat, the deviation rectifying mechanism is quickly applicable to rectifying the currently conveyed materials, so that the deviation rectifying efficiency is improved, and the deviation rectifying efficiency is higher.
