Detailed Description
The following will describe the solution of the apparatus for measuring and sorting contamination of clothes according to the embodiments of the present invention in detail by using several specific embodiments.

The laundry contamination measuring and sorting apparatus further includes a lower detector 40, and the lower detector 40 is disposed at a lower side of the conveyor belt 7.

For example, the upper detector 4 includes a monitoring tip body, a first detector 41 and a second detector 42, the monitoring tip body at least includes a first isolation chamber 43 and a second isolation chamber 44 which are isolated from each other, a grid baffle 45 is disposed between the first isolation chamber 43 and the second isolation chamber 44, and the grid baffle 45 is made of a radiation shielding material so as to prevent mutual interference of detection devices in the first isolation chamber 43 and the second isolation chamber 44. For ease of measurement, the opening of the first isolation chamber 43 and the opening of the second isolation chamber 44 are on the same side of the monitoring tip body. The monitoring end body can be made of lead materials, boron polyethylene plates and radiation-proof paint used for radiation protection in the prior art.
Two holding cavities are formed in the monitoring head body and are divided into a first isolation chamber 43 and a second isolation chamber 44, the first isolation chamber 43 is used for holding a first detector 41, the first detector 41 is arranged in the first isolation chamber 43, and the detection end of the first detector 41 faces the opening of the first isolation chamber 43. The first detector 41 detects the external analyte 3 through the opening of the first isolation chamber 43.
The second isolation chamber 44 is used for accommodating the second detector 42, the second detector 42 is arranged in the second isolation chamber 44, and the detection end of the second detector 42 faces the opening of the second isolation chamber 44. The second detector 42 detects the external analyte 3 through the opening of the second isolation chamber 44.
The above example provides the upper detector 4, in which the first isolation chamber and the second isolation chamber having the same side and isolated from each other are used, and the first detector and the second detector are disposed in the first isolation chamber and the second isolation chamber. The upper detector 4 has the function of detecting multiple pollution sources for the detected clothes at one time, so that the detection efficiency is improved, and the problem of missed detection is avoided.
In the above-mentioned conveying device, as shown in fig. 2, the belt of the conveying device is located at the bottom of the upper detector 4, and the detecting end of the upper detector 4 faces the conveying end face of the belt. The conveyor belt 7 of the above-mentioned conveyor is knitted by knitting yarn, the conveyor belt 7 includes a friction portion 75 located on the conveying surface of the conveyor belt 7, the friction portion 75 is composed of a plurality of knitting yarn segments, the knitting yarn segments are a part of the knitting yarn, a part of the knitting yarn segments are in a first position state relative to the body of the conveyor belt 7, and another part of the knitting yarn segments are in a second position state relative to the body of the conveyor belt 7; the braided wire segment in the first position state generates a first axial force component in the axial direction of the first roller 9 with the first roller 9 at a portion where the friction portion 75 contacts the first roller 9; the braided wire section in the second position state generates a second axial component force along the axial direction of the first roller 9 with the first roller 9; the first axial force component and the second axial force component may cancel.
The above-mentioned conveyer belt 7 is used for moving under the drive of first cylinder 9 and second cylinder 8, includes: and the weaving wires are woven into the conveying belt 7 with a net structure. The conveyor belt 7 is formed by weaving and connecting one or more weaving wires into a net. The conveyor belt 7 may also be formed by a plurality of annular knitted wire loops that are connected together. For example, as shown in fig. 5, the annular knitting yarns include a plurality of first annular knitting yarns 71, a plurality of second annular knitting yarns 72, and a plurality of third annular knitting yarns 73, the plurality of third annular knitting yarns 73 are located in the middle of the conveyor belt 7, and the plurality of third annular knitting yarns 73 are sequentially connected with each other along the longitudinal direction of the conveyor belt 7 to form a force-bearing skeleton. The first annular weaving wires 71 are located on one side of the bearing framework, and the second annular weaving wires 72 are located on the other side of the bearing framework. The conveyor belt 7 composed of the first annular braided wire 71, the second annular braided wire 72 and the third annular braided wire 73 can ensure that the conveyor belt 7 has a looser structure and still has a stronger supporting force under the condition of larger aperture. The braided wire may be of metal or plastic material.
In one example, a plurality of said first endless braided wires 71 are interconnected to form a first half-belt 7, and a plurality of said second endless braided wires 72 are interconnected to form a second half-belt 7; the first half conveyor belt 7 is connected with one side of the bearing framework, and the second half conveyor belt 7 is connected with the other side of the bearing framework.
In another example, the first looped shaped braid 71 is the same shape as the second looped shaped braid 72, the first looped shaped braid 71 having the braid segments thereon, the second looped shaped braid 72 having the braid segments thereon; the first annular weaving wire 71 and the second annular weaving wire 72 on two sides of the bearing framework are distributed in a relative mirror image manner; the weaving wire segments of the first annular weaving wire 71 and the weaving wire segments of the second annular weaving wire 72 are distributed in a mirror image mode. In this example, the purpose of the mirror image distribution of the knitting yarn segments of the first annular knitting yarn 71 and the second annular knitting yarn 72 is that the knitting yarn segments of the first annular knitting yarn 71 generate a first component force along the radial direction of the first roller 9 under the driving of the first roller 9, and in order to cancel the first component force, the knitting yarn segments of the second annular knitting yarn 72 and the first roller 9 generate a second component force opposite to the first component direction, and at this time, the knitting yarn segments of the first annular knitting yarn 71 and the second annular knitting yarn 72 need to be mirror image distributed. This example provides two forces in opposite directions on the conveyor belt 7 in the radial direction of the first roller 9, so that when the conveyor belt 7 is driven by the first roller 9, the problem that the conveyor belt 7 is shifted to the first roller 9 side relative to the first roller 9 is reduced.
In one embodiment, one side of the third circular knitting wire 73 is connected to one of the first circular knitting wires 71, and the other side of the third circular knitting wire 73 is connected to one of the second circular knitting wires 72; the length from the top to the bottom of the third circular knitting yarn 73 is gradually reduced or gradually increased; the third looped threads 73 are configured to maintain a relatively mirrored distribution of the first looped threads 71 and the second looped threads 72. The third circular knitting wire 73 may have a circular shape, such as a trapezoid, a triangle, in a relatively radial direction along its center line.
The conveyor belt 7 includes a friction portion 75 located on the conveying surface of the conveyor belt 7, and the friction portion 75 is composed of a plurality of braided wire segments, the braided wire segments are a part of the braided wires, a part of the braided wire segments are in a first position state relative to the body of the conveyor belt 7, and another part of the braided wire segments are in a second position state relative to the body of the conveyor belt 7. The friction portion 75 is a surface portion of the conveyor belt 7, and when the first roller 9 drives the conveyor belt 7 to run, the first roller 9 will contact with the surface portion of the conveyor belt 7, i.e., the friction portion 75. The friction portion 75 generates a force component with the first roller 9 in the radial direction of the first roller 9. With respect to conveyor belt 7, as shown in fig. 5, in one embodiment, conveyor belt 7 is illustrated with specific a braided wire segment 711, B braided wire segment 712, C braided wire segment 713, D braided wire segment 714, E braided wire segment 721, F braided wire segment 722, G braided wire segment 723, and H braided wire segment 724 of a plurality of braided wire segments.
For example, the a-braid segment 711 is a bottom portion of the first endless braid 71, and when the first roller 9 drives the conveyor belt 7 to run, the a-braid segment 711 contacts with the surface of the first roller 9. In fig. 5, since the diameter of the a-braid wire segment 711 is angled with respect to the radial direction of the first roller 9, a first axial force component is generated between the a-braid wire segment 711 and the first roller 9 relative to the axial direction of the first roller 9, which causes the conveyor belt 7 to deflect in the axial direction of the first roller 9. The principle and effect of braided wire section B712, braided wire section C713 and braided wire section D714 in fig. 1 are the same as those of braided wire section a 711, and thus are not described again.
The E-weaving yarn section 721 is the bottom portion of the second circular weaving yarn 72, and when the first roller 9 drives the conveyor belt 7 to run, the E-weaving yarn section 721 contacts with the surface of the first roller 9. In fig. 1, the E-braid segment 721 and the first roller 9 generate a second axial component of the conveyor belt 7 with respect to the axial direction of the first roller 9 due to the diameter of the E-braid segment 721 being angled with respect to the radial direction of the first roller 9. This second axial component will deflect the conveyor belt 7 in the axial direction of the first roller 9. And the second axial force component is opposite to the first axial force component in direction, and the two components can be mutually offset. The principle and effect of the F braided wire segment 722, the G braided wire segment 723 and the H braided wire segment 724 in fig. 5 are the same as those of the E braided wire segment 721, and thus the description thereof is omitted.
At the portion where the friction portion 75 contacts the first roller 9, the braided wire section in the first position state generates a first axial force component in the axial direction of the first roller 9 with the first roller 9. The length of knitting yarn in the second position generates a second axial force component with the first roller 9 in the axial direction of the first roller 9. The first axial force component and the second axial force component are opposite in direction. Eventually the first axial force component and the second axial force component may cancel.
As for the above-described conveyor belt 7, referring to fig. 6 and 7, compared with the prior art transmission network 74, the friction portion 75 is set to two position states, i.e., a first position state and a second position state. The weaving silk section in the first position state and the first roller 9 generate a component force in one direction, the weaving silk section in the second position state and the first roller 9 generate a component force in the other direction, and the single axial direction offset force of the conveyor belt 7 and the rollers is eliminated through mutual offset of the forces between the weaving silk sections in the two position states. Finally, the noise and the damage at the position of the roller limiting shaft are avoided.
As shown in fig. 3, the lifting device 6 is used for adjusting the height of the upper detector 4, and the upper detector 4 is disposed at the lifting end of the lifting device 6. When the lifting device 6 is selected, a servo lifting mechanism capable of accurately controlling the lifting height needs to be selected, for example, the servo lifting mechanism can be a rack lifter SP100 synchronous lifting platform servo rack lifter with the model of RJ30-4 SH. The servo lift mechanism may also be a ball screw jack of type N5-L-GQ-2-600.
In another embodiment of the automatic lifting detection mechanism of the clothes contamination measuring and sorting instrument according to the present invention, as shown in fig. 3, the lifting device 6 comprises a motor, a transfer mechanism, a transmission mechanism and a plurality of lifting mechanisms 63, wherein the power input end of the transfer mechanism is in transmission connection with the motor, the output end of the transfer mechanism is provided with a plurality of output ends, and the power input end of each lifting mechanism 63 is in transmission connection with one output end of the transfer mechanism through the transmission mechanism. One end of the transmission mechanism is meshed with the output end of the transfer mechanism, and the other end of the transmission mechanism is meshed with the power input end of the lifting mechanism 63. The motor may be a common driving motor, a servo motor 61 or a motor with a code wheel. The transfer mechanism may be a geared motor having multiple outputs. The transmission mechanism is used for transmitting the power of each output end of the transfer mechanism to each lifting mechanism 63. When the lifting mechanism 63 is selected, a servo lifting mechanism capable of accurately controlling the lifting height needs to be selected, for example, the servo lifting mechanism can be a rack lifter SP100 synchronous lifting platform servo rack lifter with the model of RJ30-4 SH. The servo lift mechanism may also be a ball screw jack of type N5-L-GQ-2-600. Divide into a plurality of outputs through the power synchronization of transfer mechanism with the motor to every output and every elevating system meshing connection of rethread transmission with transfer mechanism have finally realized that a plurality of elevating gear 6 can promote under higher precision in step. Wherein, each output end is provided with a lead screw 64 and a nut, and the lead screw 64 and the nut form the working end of the lifting mechanism.
In one example, as shown in fig. 3, the transfer mechanism comprises a first transmission reverser 62 and a plurality of transmission screws 65, wherein the transmission screws 65 are in meshing connection with each other through the first transmission reverser 62;
the first drive reverser 62 is two intermeshing bevel gears 612, as shown in FIG. 4;
the plurality of drive screws 65 are perpendicular to each other;
the plurality of driving screws 65 are connected in a driving manner, and the plurality of driving screws 65 are connected in series. The plurality of drive screws 65 connected in series are synchronously driven and can be conveniently installed front and back.
Or a plurality of the transmission screws 65 are connected with each other to form a loop. The synchronism between the plurality of drive screws 65 constituting the circuit is higher. When driving a plurality of elevating system, a plurality of elevating system synchronism is stronger at the during operation.
As shown in fig. 2, the height detection sensor 1 is disposed at the conveying opening of the conveyor belt 7, and the height detection sensor 1 is disposed at the conveying opening. The height detection sensor 1 is used to measure the height of the object 3. The height detecting sensor 1 may be a correlation type product height detecting sensor model number CM 40-S960. The height detection sensor 1 may also be a height measurement system including a laser and a CCD camera, and specific references may be made to "introduction of principle of measuring visual height in automated visual testing (laser and CCD camera)".
And the control system is electrically connected with the lifting device 6 and the height detection sensor 1 and is used for acquiring the height of the object to be detected 3 detected by the height detection sensor 1 and controlling the lifting device 6 to lift so as to enable the detection end of the upper detector 4 to be higher than the height of the object to be detected 3. After acquiring the detection signal of the height detection sensor 1, the control system acquires the height of the object to be detected 3. And then the control system controls the lifting device 6 to ascend according to the detection signal of the height detection sensor 1 until the detector 4 is higher than the height of the object to be detected 3.
For example, the control system comprises a processor and a communication interface coupled to the processor, the processor being configured to perform the following steps 1-3:
step 1, sending a first control signal to a lifting device 6, wherein the first control signal is used for adjusting a lifting end of the lifting device 6 to a preset position;
and 3, sending a second control signal to the lifting device 6.
Specifically, the height value has a plurality of values, and each of the height values corresponds to one of the second control signals. For example: the control system comprises a controller and a plurality of data registers for storing the rotation angle data of the output end of the servo motor 61, and each data register corresponds to one second correlation detector 2;
the controller is electrically connected with the servo motor 61 and the data registers, and is used for selecting the data register corresponding to the second correlation detector 2 which is at the lowest height and does not detect the object to be detected on the height detection sensor 1, and controlling the servo motor 61 to rotate the rotating angle registered in the data register.
In the above embodiment, the height detection sensor 1 including the plurality of second correlation detectors 2 is used, and although the accuracy is lowered when the object 3 to be measured is measured, the entire system tends to be simplified when the servo motor 61 and the plurality of data registers are used in combination.
For example, if the height detection sensor 1 has three second correlation detectors 2, the control system has three data registers.
The above initial conditions were as follows:
1. the second correlation detectors 2 are divided into a correlation detector 11, a correlation detector 12 and a correlation detector 13 from near to far from the conveyor belt 7. The a-correlation detector 11 is located at 10cm of the conveyor belt 7. The b-correlation detector 12 is located 15cm from the conveyor belt 7. The c-correlation detector 13 is located at 20cm of the conveyor belt 7.
2. The data registers are divided into an A data register, a B data register and a C data register. The a data register stores data of 100 rotations of the servo motor 61 from the initial position. The B data register stores data of 150 rotations of the servo motor 61 from the initial position. The C data register stores data of 200 rotations of the servo motor 61 from the initial position.
3. When the servo motor 61 works, when the servo motor 61 rotates to 100 circles from the initial position, the lifting end of the lifting device 6 lifts the detection end of the detector 4 to a position of 15 cm. When the servo motor 61 rotates 150 circles from the initial position, the lifting end of the lifting device 6 lifts the detection end of the detector 4 to 20 cm. When the servo motor 61 rotates 200 circles from the initial position, the lifting end of the lifting device 6 lifts the detection end of the detector 4 to 35 cm.
The operation results are as follows:
1. when the object 3 passes through the height detection sensor 1 under the driving of the conveyor belt 7, if the object 3 blocks the a correlation detector 11, the controller reads the data registered by the a data register. The servomotor 61 rotates to 100 turns.
2. When the object 3 to be detected passes through the height detection sensor 1 under the driving of the conveyor belt 7, if the object 3 to be detected shields the a correlation detector 11 and the B correlation detector 12, the controller reads the data registered by the B data register. The servomotor 61 rotates up to 150 turns.
3. When the object 3 passes through the height detection sensor 1 under the driving of the conveyor belt 7, if the object 3 blocks the a correlation detector 11, the b correlation detector 12 and the C correlation detector 13, the controller reads the data registered by the C data register. The servo motor 61 rotates up to 200 turns.
In the above example, by point-to-point correspondence of the measuring end of the height detection sensor 1 and the control position point of the controller, the control process of the control system can be simplified. So that the control system can react quickly. For example, the controller may employ a plc controller, and the pid function in the plc is used to perform the above control operation.
The automatic lifting detection mechanism of the clothes pollution measurement sorting instrument further comprises a conveyor belt 7, the conveyor belt is located at the bottom of the detector 4, and the detection end of the detector 4 is aligned to the conveying end face of the conveyor belt. After the lifting device 6 drives the detector 4 to rise to a height higher than the object to be detected 3, the transmission belt can drive the object to be detected 3 to pass through the detection end of the detector 4, and the purpose of detecting the object to be detected 3 is achieved. In one example, the upper detector 4, the conveyor and the lifting device 6 are mounted on a lifting bracket 5.
In conclusion, when the clothes pollution measuring and sorting instrument detects clothes, the conveying device conveys the clothes to the measuring end of the upper detector, and in the conveying process of the conveying device, the height detecting sensor, the lifting device and the control system work in a coordinated mode, so that the height of the upper detector can be automatically adjusted when the clothes pollution measuring and sorting instrument detects the clothes. The upper detector is kept at a proper distance from the clothes.
