[0002] Currently, various turnover machines, turnover doors, and rotating mechanisms in the silk reeling workshop involve the detection of multiple positions such as the turnover in place, acceleration position, deceleration position, and retraction in place during actual use. In existing equipment, multiple position detection proximity switches are generally used, and the detection piece rotating with the shaft detects and triggers each position detection proximity switch. After the signal is sent to the PLC, it represents the various states of the equipment. There is a problem that as long as the detection piece approaches the detection proximity switch, each position signal will be triggered even when it is not completely facing it directly, resulting in inaccurate detection positions. Moreover, after the detection piece moves, the equipment position signal cannot be accurately reset. If the detection setting position moves slightly, the detection in place will be inaccurate, the material container will rotate excessively and cannot be unloaded when pressed tightly against the inlet and outlet roller conveyors, or the rotation angle between the deceleration position and the in-place position is too small, causing too large rotational inertia and damaging the equipment.
[0003] Therefore, how to provide a rotating position detection device for a rotating device has become a technical problem urgently to be solved in this field. Summary of the Utility Model

[0035] It should be noted that: similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0036] The present invention provides a rotational position detection device for a rotating device, as shown in Figure 1 and Figure 2As shown, the rotation position detection device includes a rotation position detection device 100, a position detection device 200, and a PLC;
[0037] The rotation position detection device 100 is in a spoke shape and includes an outer ring 6 and an inner ring 9. The outer ring 6 and the inner ring 9 are connected by spokes 5. There are 4 spokes 5, and the outer ring 6 is equally divided into four parts; on the arc surface of the outer ring 6, there are long holes 8. On the semi-circle of the outer ring divided by the spokes 5, 4 such long holes 8 are equidistantly arranged; on the inner ring 9, there are circular holes for installing a central shaft sleeve 7;
[0038] As Figure 3 shown, the position detection device 200 includes a fixed base frame 21, a position detection proximity switch 22, and a fixed bracket 23; the position detection proximity switch 22 is installed on the fixed bracket 23, and the fixed bracket 23 is arranged on the fixed base frame 21;
[0039] The rotation position detection device 100 further includes a detection hole position adjustment piece 1. The detection hole position adjustment piece 1 is composed of a first arc piece 10 and a second arc piece 11 that are perpendicular to each other. There are 4 detection hole position adjustment pieces 1, which are respectively buckled on the outside of 4 long holes 8; the first arc piece 10 can be buckled on the outer surface of the outer ring 6; on the second arc piece, there are circular holes, and the detection hole position adjustment piece 1 is fixedly installed on the outer ring 6 through a set screw 3; 4 detection hole position adjustment pieces 1 can slide along the outer side surface of the detection hole cylinder to adjust the position of the detection hole 2. After sliding to the appropriate position, it is fixed with a set screw 3.
[0040] Of course, in some embodiments, the detection hole position adjustment piece 1 can also be arranged on the inner side surface of the detection hole cylinder and can slide and set on the inner side surface of the detection hole cylinder. When the detection hole position adjustment piece is adjusted to any position within the range where the position of the detection hole 2 can be adjusted, it can completely cover the long hole 8. Therefore, the detection hole 2 can only be set within a certain range.
[0041] In some embodiments, a detection circular hole 2 is provided on the first arc piece 10. The detection circular hole 2 can be arranged corresponding to the long hole; the rotation position detection device 100 is installed on the rotating shaft of the rotating device through the central shaft sleeve 7; the position detection proximity switch 22 is perpendicular to the rotating shaft and faces the rotation position detection device 100; the PLC collects the signal of the position detection proximity switch 22 and controls the rotating motor.
[0042] In some specific embodiments, the diameter of the detection round hole 2 is greater than the diameter of the circular end face detected by the position detection proximity switch 22, and the position detection proximity switch 22 is a magnetic proximity switch; the circular face size of the magnetic proximity switch should not be too large and must be smaller than the size of the detection hole 2 to ensure that the detection result is zero when the detection hole is directly opposite the magnetic proximity switch. Considering the rotational inertia of the motor, the detection hole 2 can also be set as a long hole type to ensure that the motor can accurately measure the position even with a small amount of inertia.
[0043] In some specific embodiments, scale lines 4 are provided on the side surface of the outer ring 6, and the scale lines are used to identify the position setting angle of the device. This can prevent the detection hole position adjustment piece 1 from being misadjusted and can be accurately reset according to the record.
[0044] In some specific embodiments, the device further includes a mechanical limit anti-collision block, and the mechanical limit anti-collision block is installed at the rotation limit position of the rotating device.
[0045] The rotation position detection device 100 in this application is installed on the rotating shafts of various box turning machines, turning doors, and rotating mechanism motors in the workshop. In cooperation with the position detection proximity switch, by detecting and judging the detection hole, four state positions, namely the initial lifting position, acceleration position, deceleration position, and lifting stop position, are identified, which determine the start, stop, and running speed of the rotating motor.
[0046] Working principle:
[0047] The signal acquisition, processing, and judgment process includes signal acquisition input, PLC algorithm processing, and output execution. After the digital quantity signal is collected into the PLC, the rotating device stops at the falling-in-place position, and the first detection hole comes into play. At this time, the device state is 0. After the flipping device receives the running instruction, it starts to rotate and leaves the first detection hole. After the second detection hole comes into play, the device state becomes 1; it starts to accelerate. After accelerating to the third detection hole, the device state is 2, and the rotating device starts to decelerate. After decelerating to the position of the fourth detection hole, the device state is 3. Considering inertia, the device is stopped, and the device state is set to 0 after the device stops. When the rotating device rotates in reverse, the program executes in reverse.
[0048] As described above, the signal acquisition, processing, judgment, and output device includes signal acquisition, control algorithm, and output execution. The control algorithm design uses the step sequence control principle. The initial position M0 is set. After M0 is turned on, it controls a certain result. After the result is achieved, M0 is reset, and then M1 is set. The process control is carried out in sequence to ensure that the device works according to the pre-designed technological process.
[0049] In summary, through the above design, the present application can accurately identify the starting position, acceleration position, deceleration position, and arrival position of the rotating motor with only one proximity switch. Moreover, since the detection hole is directly opposite to the detection proximity switch to indicate the arrival of the position, the detection position is more accurate, avoiding the inaccurate identification of the original magnetic proximity switch being triggered when the detection piece reaches half or slightly of the magnetic proximity switch. Compared with the existing detection device, the number of magnetic proximity switches is simplified, it is easy to adjust and set, and the detection is more accurate. It effectively improves the stability and accuracy of the equipment operation.
