Detailed Description
The present invention will be described in further detail with reference to examples.
In the specific implementation: as shown in fig. 1 and 2, a longitudinal belt deviation rectifying device without a standing bar comprises a support 1 transversely arranged at the bottom of a longitudinal belt, wherein the support 1 is provided with a deviation rectifying wheel 2 arranged along the length direction of the longitudinal belt, the deviation rectifying wheel 2 is rotatably arranged on the support 1 through an eccentric rotating shaft 3 eccentrically arranged, and the distance from the axis of the eccentric rotating shaft 3 to the longitudinal belt is greater than the minimum distance from the circumferential surface of the deviation rectifying wheel 2 to the axis and is less than the maximum distance from the circumferential surface of the deviation rectifying wheel 2 to the axis; one end of the eccentric rotating shaft 3 is connected with a deviation rectifying motor 4; the device also comprises sensing mechanisms 5 for detecting the deviation of the longitudinal belt, wherein the sensing mechanisms 5 are arranged on two sides of the longitudinal belt in pairs in the width direction; the sensing mechanism 5 is connected to an electric control system of the deviation rectifying motor 4.
Because eccentric setting of eccentric pivot is on rectifying the wheel, rectify the minimum radius of wheel simultaneously and be less than the eccentric pivot and to the distance of vertical belt bottom, and rectify the maximum radius of wheel and be greater than the eccentric pivot and to the distance of vertical belt bottom for eccentric pivot drives and rectifies the wheel rotation in-process, rectifies the wheel and can contact with vertical belt intermittently, and rectifies the wheel and set up along the length direction of vertical belt, when rectifying wheel and vertical belt contact, can drag vertical belt towards the width direction. The sensing mechanisms on the two sides of the width of the longitudinal belt are utilized to detect the deviation direction of the longitudinal belt, the signal is transmitted to the electric control system, the rotation direction and the speed of the deviation rectifying motor are controlled, the deviation rectifying wheel can be controlled to drag the longitudinal belt towards the middle, and the deviation rectification is realized. Once the deviation rectification is completed, the minimum diameter side of the deviation rectification wheel can rotate to the upward direction, so that a space is reserved between the deviation rectification wheel and the longitudinal belt, the friction between the deviation rectification wheel and the longitudinal belt for a long time is avoided, and the service life of the longitudinal belt is prolonged. In specific implementation, the deviation correcting wheel can be an eccentric wheel or a cam.
In this embodiment, the sensing mechanism 5 includes a friction wheel 51 disposed on one side in the width direction of the longitudinal belt, the rotating shaft of the friction wheel 51 is disposed along the width direction of the longitudinal belt, and one end of the friction wheel 51 facing the longitudinal belt is disposed on the edge of the longitudinal belt in an engaging manner; a rotating speed sensor 52 is arranged on a rotating shaft of the friction wheel 51, and the rotating speed sensor 52 is connected to an electric control system of the deviation rectifying motor 4. In order to ensure that the belt edge is more reliably contacted with the friction wheel when the longitudinal belt deviates, one end of the friction wheel 51 facing the longitudinal belt is lower than the edge height of the longitudinal belt in a normal working state, and the other end of the friction wheel is inclined upwards and is higher than the edge height of the longitudinal belt.
Because the friction pulley links up the edge that sets up at vertical belt towards the one end of vertical belt, in case vertical belt off tracking, its edge will contact with the friction pulley, and then drive the friction pulley and rotate, just can detect the rotation signal of friction pulley through speed sensor, install the position (left side or right side) at vertical belt according to the friction pulley that speed sensor corresponds, just can judge vertical belt towards left side or right side off tracking, and then can control the motor that rectifies and drive the wheel that rectifies and rotate towards opposite one side and drag vertical belt and realize rectifying.
When the device is specifically arranged, the support 1, the deviation rectifying wheel 2 and the sensing mechanism 5 can be arranged at the same length position of the longitudinal belt, or the support 1 and the sensing mechanism 5 can be distributed along the length direction of the longitudinal belt, and the support 1 is positioned on one side of the sensing mechanism 5 facing the feeding end of the longitudinal belt. The two are distributed along the length direction of the longitudinal belt, so that the deviation can be detected by the sensing mechanism, and the deviation rectifying wheel can rectify the deviation in advance in front of the sensing mechanism.
Because the deviation rectifying wheel needs to be contacted with the bottom of the longitudinal belt in the deviation rectifying process, and needs to be separated from the longitudinal belt after the deviation rectifying process is finished, and abrasion caused by long-term contact is avoided. Meanwhile, considering that the running environment and the working condition of the longitudinal belt are complex and easily cause electrical faults, once the electrical faults occur, the deviation rectifying wheel is in a state of being in contact with the longitudinal belt for a long time, the longitudinal belt can be damaged, and huge loss is caused. For this reason, in the present embodiment, an automatic adjustment structure is also adopted as follows.
Specifically, as shown in fig. 3, the eccentric rotating shaft 3 is obliquely arranged along the width direction of the longitudinal belt, so that an included angle of 30 to 45 degrees is formed between the axis of the eccentric rotating shaft 3 and the conveying direction of the longitudinal belt, the deviation rectifying wheel 2 is relatively rotatably arranged on the eccentric rotating shaft 3, and a normally open type electromagnetic clutch mechanism 6 is arranged between the deviation rectifying wheel 2 and the eccentric rotating shaft 3.
Therefore, once the deviation rectifying wheel is required to rectify the deviation of the longitudinal belt, the deviation rectifying wheel can be combined with the eccentric rotating shaft through the electromagnetic clutch mechanism, and the deviation rectifying motor is used for driving the deviation rectifying wheel to rectify the deviation of the longitudinal belt. After the deviation rectification is finished, the normally open type electromagnetic clutch mechanism is powered off, and the deviation rectification wheel can freely rotate relative to the eccentric rotating shaft. Because the eccentric rotating shaft and the conveying direction of the longitudinal belt form an included angle, if the deviation correcting wheel is still contacted with the longitudinal belt when the deviation correction is finished, forward friction force is applied to the deviation correcting wheel in the conveying process of the longitudinal belt, component force for rotating the deviation correcting wheel is generated certainly, the deviation correcting wheel rotates around the eccentric rotating shaft, and finally the deviation correcting wheel rotates to the position with a gap between the deviation correcting wheel and the longitudinal belt to stop. By adopting the structure, even if an electrical fault occurs, the normally open type electromagnetic clutch mechanism can generate a gap between the deviation correcting wheel and the longitudinal belt finally under the action of the power-off characteristic and the friction component force, and the abrasion of the longitudinal belt caused by long-term friction of the deviation correcting wheel on the longitudinal belt is avoided.
Of course, in specific implementation, a normally open electromagnetic clutch mechanism may be disposed between the eccentric rotating shaft 3 and the deviation rectifying motor 4.
In the embodiment, considering that the deviation rectifying wheel needs to bear a large load during deviation rectification, the normally open electromagnetic clutch mechanism 6 adopts a jaw electromagnetic clutch, and comprises a driving combination disc 61 installed on the eccentric rotating shaft 3 and a driven combination disc 62 installed on the deviation rectifying wheel 2, wherein one side of the driving combination disc 61 opposite to one side of the driven combination disc 62 are provided with correspondingly arranged convex teeth; and the driving combination disk 61 is provided with an electromagnet for attracting the driven combination disk 62.
In order to ensure that the driving combination disk 61 and the driven combination disk 62 can be better combined and separated, a permanent magnet is embedded in the driven combination disk 62. The combination and separation between the driving combination disk and the driven combination disk can be controlled by controlling the magnetic poles of the electromagnets on the driving combination disk, and the control is more reliable.
The dog type electromagnetic clutch may not be disengaged even when a large torque is transmitted, and may be disengaged by mutual repulsion of magnetic poles, or may be provided with a disengagement spring between the driving engagement disc 61 and the driven engagement disc 62. In addition, in the embodiment, the axial friction component that the longitudinal belt may exert on the deviation rectifying wheel is fully considered and utilized, and specifically, the driving combination disk 61 is arranged on the side of the driven combination disk 62 facing the feeding end of the longitudinal belt. After the power is cut off, once the driving combination disk and the driven combination disk are not completely separated, the deviation correcting wheel can move towards the direction back to the driving combination disk under the action of the friction force of the longitudinal belt, so that the separation probability is improved, and the structure is more reliable.
As shown in fig. 2 and 3, in this embodiment, in order to increase the output torque of the deviation-correcting motor 4, a speed reducer is further disposed between the deviation-correcting motor and the eccentric rotating shaft 3.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
