Description

Technical Field

[0001] This application relates to the field of tape production, and in particular to a clutch device for a feeder. Background Art

[0002] Feeders play an important role in industrial production with their advantages of high efficiency, precision, and automation. It can continuously and stably transport materials accurately to the designated processing positions, greatly improving production efficiency, reducing the complexity and errors of operator operations, and is an essential important device in modern manufacturing.

[0003] During the process of a feeder transporting materials, the traditional method requires frequently controlling the start and stop of the conveyor belt through a controller, so that the materials are parked at the workstations to be processed. Frequent starting and stopping of the motor easily leads to problems such as overheating of the motor and shortening of the motor life; the existing start-stop adopts a clutch structure. When the feeder needs to pause, the motor and the transmission mechanism can be separated, causing the feeder to brake.

[0004] During the braking process of the clutch structure on the motor and the transmission mechanism, the clutch structure needs to apply a certain force to the transmission mechanism to achieve braking (which can be achieved by an operator manipulating the working state of the clutch structure). However, in actual applications, there is a situation of stuck braking, which causes the materials to not accurately stay at the designated position of the feeder, affecting the subsequent feeding process of the feeder, and there is room for improvement. Summary of the Utility Model

[0005] In order to improve the reliability of a feeder when transporting materials, this application provides a clutch device for a feeder.

[0006] The clutch device for a feeder provided by this application adopts the following technical solution:[[]]

[0007] A clutch device for a feeder includes a clutch fixed adjustment seat, a driving component, a clutch guard, and a clutch paddle. The clutch fixed adjustment seat is arranged on the feeder. The clutch guard is connected to the clutch fixed adjustment seat. The driving component is arranged on the clutch guard. The clutch paddle is rotatably carried on the clutch guard. The clutch paddle is connected to the driving component. The driving component is used to drive the clutch paddle to perform circumferential rotation. The driving component is electrically connected to a controller. When the driving component drives the clutch paddle to be initially in contact with the transmission mechanism, the feeder continuously transports materials. When the driving component drives the clutch paddle to rotate along the transmission mechanism to the limit position, the feeder stops transporting materials.

[0008] By adopting the above technical solution, the driving component drives the clutch paddle to rotate along the clutch guard. At the same time, the controller is used to control the angle and speed of the driving component driving the clutch paddle to rotate along the clutch guard, so that the clutch paddle can rotate controllably along the clutch guard. The clutch paddle is used to drive the transmission mechanism to act, thereby indirectly controlling the power transmission between the transmission mechanism and the motor of the feeder, reducing the necessity for operators to participate in the feeding control of the feeder. Through the cooperation of the controller and the driving component, it plays a positive guiding role in reducing the probability of the brake getting stuck, which is beneficial to improving the stability of the feeder when conveying materials.

[0009] Preferably, a first connecting sleeve is arranged on the clutch fixed adjustment seat. A clutch adjustment part is inserted into the first connecting sleeve. The clutch adjustment part is connected to the clutch guard. The clutch adjustment part is used to adjust the distance between the clutch guard and the clutch fixed adjustment seat, and / or the deflection angle between the clutch guard and the clutch fixed adjustment seat.

[0010] By adopting the above technical solution, through the cooperation of the first connecting sleeve and the clutch adjustment part, the adjustment of the distance between the clutch guard and the clutch adjustment part is realized, and the angle between the clutch guard and the horizontal plane can be adjusted, so that the spatial position of the clutch paddle can be indirectly adjusted to meet the working requirements of different working occasions.

[0011] Preferably, second connecting sleeves are arranged on the side wall of the clutch guard facing the clutch fixed adjustment seat in the same direction along the length direction of the clutch guard. The clutch adjustment part is inserted into the second connecting sleeves. The clutch adjustment part is used to adjust the distance between the clutch guard and the clutch fixed adjustment seat in the vertical direction.

[0012] By adopting the above technical solution, through the cooperation of the second connecting sleeve and the clutch adjustment part, the adjustment of the distance between the clutch guard and the clutch fixed adjustment seat in the vertical direction is realized, so that the adjustment of the height distance of the clutch paddle in the vertical direction is indirectly realized, and the practicability is high.

[0013] Preferably, a photoelectric switch is arranged on the side wall of the clutch guard close to the clutch paddle. The photoelectric switch is electrically connected to the controller.

[0014] By adopting the above technical solution, through the detection function of the photoelectric switch, when the controller controls the driving component to act, the clutch paddle rotates following the driving component. When the clutch paddle rotates into the detection area of the photoelectric switch (i.e., when the clutch paddle blocks the photoelectric switch), the photoelectric switch is quickly turned on, thereby sending a detection signal to the controller, and the controller controls the driving component to stop acting. Through the cooperation of the photoelectric switch and the controller, it is beneficial to improve the response ability of the driving component and reduce the probability that the clutch paddle cannot drive the transmission mechanism to act due to the deviation of the angle at which the driving component drives the clutch paddle to rotate along the clutch housing, resulting in the situation that the feeder cannot stay at the set position relatively accurately.

[0015] Preferably, the driving component includes a driving motor and a speed reducer. The driving motor and the speed reducer are sequentially arranged in the clutch housing. The output shaft of the driving motor is connected to the input end of the speed reducer, and the clutch paddle is coaxially fixed to the output end of the speed reducer.

[0016] By adopting the above technical solution, the speed reducer reduces the speed of the output shaft of the driving motor. At the same time, through the step-by-step deceleration effect of the speed reducer, the torque output by the output shaft of the driving motor can be increased, and the probability of the situation that the clutch paddle slips or is not sufficient to drive the transmission mechanism to act due to insufficient torque transmitted to the clutch paddle is reduced.

[0017] Preferably, a waist-shaped slot is formed in the clutch fixed adjustment seat.

[0018] By adopting the above technical solution, the flexible adjustment of the installation position of the clutch fixed adjustment seat on the feeder can be realized through the waist-shaped slot, which is beneficial to improving the versatility of the clutch device.

[0019] Preferably, the clutch housing is formed by combining metal plates with each other.

[0020] By adopting the above technical solution, the clutch housing is formed by combining metal plates with each other, which enables the clutch housing to have good bearing capacity while reducing the overall mass of the clutch housing, and is beneficial to improving the overall portability of the clutch device.

[0021] Preferably, air dispersion holes are formed through the side wall of the clutch housing in the thickness direction.

[0022] By adopting the above technical solution, the air dispersion holes are beneficial to dissipating the heat inside the clutch housing, reducing the probability of the situation that the driving motor and / or the speed reducer are damaged due to excessive heat generated when the driving motor and / or the speed reducer work. At the same time, when it is necessary to disassemble and assemble the clutch device along the feeder, the air dispersion holes facilitate the operator to hold the clutch device.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The controller is used to control the driving component to drive the clutch paddle to rotate at an angle and speed along the clutch housing, so that the clutch paddle can rotate controllably along the clutch housing. The clutch paddle is used to drive the transmission mechanism to act, thereby indirectly controlling the power transmission between the transmission mechanism and the motor of the feeder, which plays a positive guiding role in reducing the probability of jamming during braking and is beneficial to improving the stability of the feeder when conveying materials;

[0025] 2. Through the cooperation of the first connecting sleeve and the clutch adjusting part, the distance between the clutch housing and the clutch adjusting part can be adjusted, and the angle between the clutch housing and the horizontal plane can be adjusted, so that the spatial position of the clutch paddle can be indirectly adjusted to meet the working requirements of different working occasions;

[0026] 3. Through the cooperation of the photoelectric switch and the controller, it is beneficial to improve the response ability of the driving component and reduce the probability that the clutch paddle cannot drive the transmission mechanism to act due to the deviation of the angle of the driving component driving the clutch paddle to rotate along the clutch housing, resulting in the feeder being unable to stay at the set position relatively accurately.

Detailed Description of the Invention

[0030] The following will further describe the present application in detail with reference to the attached Figure 1-2 This application will be further described in detail below.

[0031] An embodiment of the present application discloses a clutch device for a feeder. Refer to Figure 1 and Figure 2, a clutch device for a feeder includes a clutch fixed adjustment seat 1, a driving component 2, a clutch guard 3, and a clutch paddle 4. The clutch fixed adjustment seat 1 is arranged on the feeder. The clutch guard 3 is connected to the clutch fixed adjustment seat 1. The driving component 2 is arranged on the clutch guard 3. The clutch paddle 4 is rotatably carried on the clutch guard 3. The clutch paddle 4 is connected to the driving component 2. The driving component 2 is used to drive the clutch paddle 4 to perform circumferential rotation. The driving component 2 is electrically connected to a controller. When the driving component 2 drives the clutch paddle 4 to be initially in contact with the transmission mechanism, the feeder continuously conveys materials. When the driving component 2 drives the clutch paddle 4 to rotate along the transmission mechanism to the limit position, the feeder stops conveying materials.

[0032] Thus, by driving the clutch paddle 4 to rotate along the clutch guard 3 through the driving component 2, at the same time, using the controller to control the rotation angle and speed of the driving component 2 to drive the clutch paddle 4 to rotate along the clutch guard 3, the clutch paddle 4 can be controllably rotated along the clutch guard 3, and the clutch paddle 4 is used to drive the transmission mechanism to act, thereby indirectly controlling the power transmission between the transmission mechanism and the motor of the feeder, reducing the necessity for operators to participate in the feeding control of the feeder. Through the cooperation of the controller and the driving component 2, it plays a positive guiding role in reducing the probability of jamming during braking, which is beneficial to improving the stability of the feeder when conveying materials.

[0033] Specifically, a waist-shaped groove 8 is formed on the clutch fixed adjustment seat 1. The waist-shaped groove 8 is formed along the length direction of the clutch fixed adjustment seat 1 and runs through the clutch fixed adjustment seat 1 along the thickness direction. Bolts can be used to fix the clutch fixed adjustment seat 1 to the feeder (or other installation positions). Through the waist-shaped groove 8, the installation position of the clutch fixed adjustment seat 1 on the feeder can be flexibly adjusted to meet the installation requirements of different positions.

[0034] In addition, the clutch guard 3 is formed by combining metal plates. By connecting several metal plates to form the clutch guard 3 for installing the driving component 2, while the clutch guard 3 formed by combining metal plates has good load-bearing capacity, it can reduce the overall mass of the clutch guard 3, which is beneficial to improving the overall portability of the clutch device.

[0035] On the other hand, a vent hole 9 runs through the side wall of the clutch guard 3 along the thickness direction. Through the vent hole 9, it is beneficial to dissipate the heat inside the clutch guard 3, reducing the probability of damage to the driving motor 21 and / or the reducer 22 caused by excessive heat generated during the operation of the driving motor 21 and / or the reducer 22. At the same time, when it is necessary to disassemble and assemble the clutch device along the feeder, through the vent hole 9, it is convenient for operators to hold the clutch device.

[0036] Furthermore, a first connecting sleeve 5 is provided on the clutch fixing and adjusting seat 1. A clutch adjusting member 6 is inserted into the first connecting sleeve 5. The clutch adjusting member 6 is connected to the clutch guard 3. The clutch adjusting member 6 is used to adjust the distance between the clutch guard 3 and the clutch fixing and adjusting seat 1, and / or the deflection angle between the clutch guard 3 and the clutch fixing and adjusting seat 1. The outer contour of the first connecting sleeve 5 is cylindrical. It is fixedly connected to the clutch fixing and adjusting seat 1 by welding or integrally formed with the clutch fixing and adjusting seat 1. A through hole 10 is drilled through the first connecting sleeve 5 along the height direction from the geometric center of the end face. The interface contour of the clutch adjusting member 6 is adapted to the contour of the through hole 10, and the tolerance fit relationship between the clutch adjusting member 6 and the through hole 10 is clearance fit, so that the clutch adjusting member 6 can smoothly slide or rotate along the through hole 10.

[0037] At the same time, a fixing threaded hole 11 is drilled through the side wall of the first connecting sleeve 5 to the through hole 10. When the clutch adjusting member 6 is adjusted to the set position along the through hole 10, the clutch adjusting member 6 can be fastened by bolts to reduce the shaking of the cooperation between the clutch adjusting member 6 and the first connecting sleeve 5. Through the cooperation of the first connecting sleeve 5 and the clutch adjusting member 6, the distance between the clutch guard 3 and the clutch adjusting member 6 can be adjusted, and the angle between the clutch guard 3 and the horizontal plane can be adjusted, so that the spatial position of the clutch paddle 4 can be indirectly adjusted to meet the working requirements of different working occasions.

[0038] Correspondingly, a second connecting sleeve 12 is provided on the side wall of the clutch guard 3 facing the clutch fixing and adjusting seat 1 along the length direction of the clutch guard 3. The clutch adjusting member 6 is inserted into the second connecting sleeve 12. The clutch adjusting member 6 is used to adjust the distance between the clutch guard 3 and the clutch fixing and adjusting seat 1 in the vertical direction. The cooperation relationship and installation method between the clutch adjusting member 6 and the second connecting sleeve 12 here are the same as those between the first connecting sleeve 5 and the clutch adjusting member 6. Through the cooperation of the second connecting sleeve 12 and the clutch adjusting member 6, the distance between the clutch guard 3 and the clutch fixing and adjusting seat 1 in the vertical direction can be adjusted, so that the height distance of the clutch paddle 4 in the vertical direction can be indirectly adjusted, with high practicability.

[0039] Refer to Figure 1 and Figure 2, the driving assembly 2 includes a driving motor 21 and a speed reducer 22. The driving motor 21 and the speed reducer 22 are sequentially arranged in the clutch guard 3. The output shaft of the driving motor 21 is connected to the input end of the speed reducer 22. The clutch paddle 4 is coaxially fixed to the output end of the speed reducer 22. The speed reducer 22 reduces the speed of the rotational speed output by the output shaft of the driving motor 21. At the same time, through the step-by-step speed reduction effect of the speed reducer 22, the torque output by the output shaft of the driving motor 21 can be increased, and the probability of the situation where the clutch paddle 4 slips or is insufficient to drive the transmission mechanism to act when the torque transmitted to the clutch paddle 4 is insufficient can be reduced when the clutch paddle 4 drives the transmission mechanism to act.

[0040] Referring to Figure 1 and Figure 2 , a photoelectric switch 7 is provided on the side wall of the clutch guard 3 close to the clutch paddle 4. The photoelectric switch 7 is electrically connected to the controller. Here, the photoelectric switch 7 can be an infrared sensor. In this embodiment, preferably, the photoelectric switch 7 is a proximity sensor. Through the detection function of the photoelectric switch 7, when the controller controls the driving assembly 2 to act, the clutch paddle 4 rotates following the driving assembly 2. When the clutch paddle 4 rotates to the detection area of the photoelectric switch 7 (i.e., when the clutch paddle 4 blocks the photoelectric switch 7), the photoelectric switch 7 is quickly turned on, thereby sending a detection signal to the controller, and the controller controls the driving assembly 2 to stop acting. Through the cooperation of the photoelectric switch 7 and the controller, it is beneficial to improve the response ability of the driving assembly 2 and reduce the probability of the situation where the clutch paddle 4 cannot drive the transmission mechanism to act due to the deviation of the angle of rotation of the clutch paddle 4 driven by the driving assembly 2 along the clutch guard 3, resulting in the feeder being unable to stay at the set position relatively accurately.

[0041] Finally, it should be noted that the controller is the controller of the feeder, which is a PLC (Programmable Logic Controller, programmable logic controller), including various functions such as logic control, timing control, analog control, and multi-machine communication, and has a human-machine interface for facilitating the control and adjustment of the PLC. It is an existing controller, and its specific composition and working principle will not be elaborated here.

[0042] The implementation principle of a clutch device for a feeder in an embodiment of this application is as follows: The reducer 22 reduces the rotational speed of the drive motor 21 and increases the torque output by the output shaft of the drive motor 21. The controller controls the working state of the drive motor 21, so that the clutch paddle 4 rotates along the clutch guard 3. The clutch paddle 4 is used to drive the transmission mechanism to act, thereby indirectly controlling the power transmission between the transmission mechanism and the motor of the feeder. This reduces the necessity for operators to participate in the feeding control of the feeder. Through the cooperation of the controller and the drive assembly 2, it plays a positive guiding role in reducing the probability of the occurrence of jamming during braking, which is beneficial to improving the stability of the feeder when conveying materials.

[0043] The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
