[0033] Example
[0034] Reference Figure 1 and attached Figure 2 An embodiment of the present invention provides a control device, which includes: a fixed bracket 1, including: a first fixed bracket 11 and a second fixed bracket 12 arranged at intervals in the longitudinal direction, and a longitudinal bracket 13 connected therebetween; a driving motor 2, mounted on the first fixed bracket 11, a driving shaft 21 of the driving motor 2 coaxially connected to a rotating shaft 8, the rotating shaft 8 extends in the longitudinal direction, and is respectively rotatably connected to the first fixed bracket 11 and the second fixed bracket 12; a control disc 3, coaxially mounted on the rotating shaft 8, and rotates synchronously with the rotating shaft 8, at least one metal patch 31 is arranged on the periphery of the control disc 3, and the metal patch 31 extends a preset length along the circumference of the control disc 3; and a proximity switch 4, mounted on the longitudinal bracket 13, and the longitudinal position of the proximity switch 4 corresponds to the position of the control disc 3, and the sensing end of the proximity switch 4 faces the control disc 3 for sensing the metal patch 31.
[0035] Specifically, the control device provided in this embodiment is used to control control objects such as motors and solenoid valves to achieve automated process control of equipment or assembly lines with periodicity and fixed order; the control device specifically includes: a fixed bracket 1, a drive motor 2, a control disc 3 and a proximity switch 4. The drive motor 2 drives the control disc 3 to rotate, and the proximity switch 4 senses the metal patch 31 of a specified position and length on the control disc 3 to achieve control of the control object. No PLC programming or setting of complex logic circuits is required, the operation is simple, and it is conducive to cost control.
[0036] Reference Figure 1 The fixed bracket 1 is the main structure of the device, which includes: a first fixed bracket 11, a second fixed bracket 12 and a longitudinal bracket 13. The first fixed bracket 11 and the second fixed bracket 12 are arranged at intervals along the longitudinal direction. The two can be respectively set as a plate-like structure or a bracket-like structure, etc. The first fixed bracket 11 can be set on the top side of the second fixed bracket 12; the longitudinal bracket 13 extends longitudinally and is connected between the first fixed bracket 11 and the second fixed bracket 12. The number of the longitudinal brackets 13 can be multiple, and the longitudinal brackets 13 can be set as a columnar or plate-like structure, which is not specifically limited here.
[0037] The driving motor 2 is fixedly mounted on the first fixing frame 11, and the driving shaft 21 of the driving motor 2 is located on the side facing the first fixing frame 11, and is coaxially connected with the rotating shaft 8, which extends longitudinally and is connected between the first fixing frame 11 and the second fixing frame 12, and the two ends of the rotating shaft 8 can be rotatably connected to the first fixing frame 11 and the second fixing frame 12 respectively, so that it can rotate relative to the fixed bracket 1 under the driving action of the driving motor 2; wherein, the driving shaft 21 of the driving motor 2 can be arranged to penetrate the first fixing frame 11 longitudinally, and be connected to one end of the rotating shaft 8 through the coupling 6, and the other end of the rotating shaft 8 is rotatably connected to the second fixing frame 12.
[0038] Reference Figure 2The control disc 3 is configured as a circular disc-shaped structure made of non-metallic material. The control disc 3 is coaxially mounted on the rotating shaft 8. Specifically, a through hole can be opened at the center of the control disc 3 to sleeve the control disc on the rotating shaft 8, and the control disc 3 can rotate synchronously with the rotating shaft 8. At least one metal patch 31 is arranged on the periphery of the control disc 3. Each metal patch 31 is in the shape of an arc extending along the circumference of the control disc 3 by a preset length, and its thickness can be equal to that of the control disc. The metal patch 31 on the control disc 3 is used for sensing by the proximity switch 4. The proximity switch 4 is mounted on the longitudinal frame 13. Its mounting position corresponds to the position of the control disc 3 in the longitudinal direction. The sensing end of the proximity switch 4 faces the control disc 3. When the proximity switch 4 senses the metal patch 31, it is in a conducting state, and when the proximity switch 4 does not sense the metal patch 31, it is in a truncated state. The proximity switch 4 is connected to the control object, and the corresponding control object can be driven by the on and off of the proximity switch 4.
[0039] Among them, the length of the connection time of the control object controlled by the control device provided by this embodiment is determined by the length of the metal patch 31 extending along the circumferential direction of the control disc 3, and the connection timing is determined by the installation position of the metal patch 31 on the control disc 3; in order to achieve precise positioning of the metal patch 31 on the control disc 3, angle scale lines can be provided along the circumferential direction of the outer periphery of the end face of the control disc 3, so that the metal patch 31 can be reliably installed by comparing with the angle scale. The connection method between the metal patch 31 and the control disc 3 can be but not limited to one of gluing, plugging, clamping, etc., which is not specifically limited here.
[0040] Reference Figure 2 and attached Figure 3 Taking a control disc 3 as an example, as shown in the attached drawings, two metal patches 31 can be respectively arranged within the range of 0-60° and within the range of 240°-300° on the outer circumference of the control disc 3. When the control disc 3 starts to rotate clockwise at 0°, as shown in the attached drawings, Figure 3 As shown, the horizontal axis is the rotation angle of the control disc 3, and the vertical axis is the signal of the proximity switch 4. It can be seen that the proximity switch 4 will be turned on twice when the control disc 3 rotates for one cycle. The turning on and off of the proximity switch 4 corresponds to the start and stop process of the control object.
[0041] Specifically, the diameter of the control disc 3 can be set to about 15 cm, or when the control accuracy needs to be improved, the diameter of the control disc 3 can be appropriately increased, and the thickness of the control disc 3 can be determined according to the diameter of the proximity switch 4.
[0042] According to the above, an embodiment of the present invention proposes a control device, wherein at least one metal patch 31 is provided on the outer circumference of the control disk 3, and each metal patch 31 is in the shape of an arc extending along the circumference of the control disk 3 for a preset length. The control disk 3 is driven to rotate by the driving motor 2, and the proximity switch 4 is used to sense the metal patch 31 on the control disk 3, so as to drive the corresponding control object by turning the proximity switch 4 on and off, thereby realizing automatic control of the control object, and does not require PLC programming or setting of complex logic circuits, and is simple to operate, which is conducive to cost control.
[0043] Reference Figure 1 In a specific implementation, there are multiple control discs 3 , and the number of proximity switches 4 is equal to and corresponds to the number of control discs 3 .
[0044] Specifically, in order to achieve synchronous control of multiple control objects, in the technical solution adopted by the present invention, multiple control discs 3 can be set on the rotating shaft 8, and multiple proximity switches 4 with an equal number of control discs 3 and corresponding longitudinal positions can be set on the longitudinal frame 13. Depending on the different controlled objects, the length, position and number of metal patches 31 on each control disc 3 can be set according to actual needs, so that when the driving motor 2 drives the rotating shaft 8 to rotate, synchronous control of multiple control objects can be achieved at the same time, which can further simplify the operation and reduce the cost.
[0045] In the case of setting multiple control discs 3, in order to avoid the interference of adjacent control discs 3 on the induction of the proximity switch 4, the following two arrangements may be adopted, but are not limited to:
[0046] The first arrangement is: refer to the attached Figure 1 As shown in the figure, a plurality of control discs 3 are arranged at intervals on the rotating shaft 8. Specifically, a partition plate 5 can be added between adjacent control discs 3 on the rotating shaft 8. The partition plate 5 can also be set to a disc shape, or can also be set to a rectangular disc shape, etc. The diameter of the partition plate 5 is smaller than the diameter of the control disc 3 and is made of non-metallic material; correspondingly, a plurality of proximity switches 4 are distributed at intervals along the longitudinal direction on the longitudinal frame 13. Such an arrangement can ensure that each proximity switch 4 can only sense the metal patch 31 on the corresponding control disc 3 within its sensing range.
[0047] The second arrangement is that a plurality of control discs 3 are stacked on the rotating shaft 8, and the interference of adjacent control discs 3 on the proximity switch 4 can be avoided by increasing the thickness of the control discs 3, so that the thickness of the control discs 3 is greater than the sensing range of the corresponding proximity switch 4. Correspondingly, a plurality of proximity switches 4 are distributed at intervals along the longitudinal direction on the longitudinal frame 13. Such an arrangement can also ensure that only the metal patch 31 on the corresponding control disc 3 can be sensed within the sensing range of each proximity switch 4.
[0048] Reference Figure 1 In a specific implementation, one of the control discs 3 is set as a reference disc 7, and a metal patch 31 arranged in a dot shape is set on the reference disc 7.
[0049] Specifically, in order to achieve accurate positioning of the initial position of each control disc 3, in the technical solution adopted by the present invention, one of the multiple control discs 3 can be set as a reference disc 7. The reference disc 7 only serves to locate the initial position. The metal patch 31 set thereon is different from other arc-shaped patches, and is set to be a point-shaped metal patch 31. The point-shaped here means that the extension length of the metal patch 31 is small, and the metal patch 31 can be used as a reference for determining the initial position of the process. In addition, prompting devices such as indicator lights and alarms can be set on the fixed bracket 1. When the proximity switch 4 corresponding to the reference disc 7 senses the corresponding point-shaped metal patch 31, the prompting device can send a light signal or a sound signal to prompt the staff, so that the staff can be informed that a new control cycle has begun.
[0050] Reference Figure 2 In a specific implementation, the cross-sectional shape of the rotating shaft 8 is a polygon, and a through hole 32 adapted to the rotating shaft 8 is provided in the middle of the control disc 3, so that the rotating shaft 8 drives the control disc 3 to rotate synchronously.
[0051] Specifically, in order to achieve synchronous rotation of the rotating shaft 8 and the control disc 3, in the technical solution adopted by the present invention, the rotating shaft 8 is set to a shaft body with a non-circular cross-sectional shape. Specifically, the cross-sectional shape of the rotating shaft 8 can be set to a polygonal shape such as a triangle or a rectangle, and a through hole 32 that is adapted to the cross-sectional shape and size of the rotating shaft 8 is opened in the middle of the control disc 3. Through the cooperation of the polygonal through hole 32 and the rotating shaft 8, the control disc can be driven to rotate synchronously while the driving motor 2 drives the rotating shaft 8 to rotate; such a cooperation method can achieve a convenient connection between the control disc 3 and the rotating shaft 8.
[0052] In a specific implementation, the metal patch 31 is detachably connected to the control disc 3 .
[0053] Specifically, in order to facilitate the modification of the control cycle and process, in the technical solution adopted by the present invention, the metal patch 31 can be connected to the control disc 3 in a detachable manner. The detachable connection here can specifically refer to: connection with locking parts such as bolts, or plug-in, or sliding connection, etc.
