Description

Technical Field

[0001] The invention relates to the technical field of machine cocoon selection, in particular to an internally contaminated cocoon sorting device. Background Art

[0002] As the main raw material of silk, the quality of silk cocoons directly affects the production efficiency of silk and the quality of the final product. Internally contaminated cocoons may cause cocoon breakage, silk breakage and uneven color during the reeling process, which in turn affects the market competitiveness of silk. Therefore, silk reeling factories will sort the cocoons before reeling. One of the important steps is to sort out the internally contaminated cocoons such as inner printed cocoons and bleeding pupa cocoons without opening the cocoons, which have no obvious surface features but the cocoon layer has been contaminated.

[0003] At present, manual screening is widely used, which has the disadvantages of high labor intensity and inconsistent classification standards. Although there are studies on the use of near-infrared equipment and X-ray equipment for identification, and the accuracy rate is also good, the near-infrared spectrometer, X-ray detector and other instruments and equipment are expensive, do not meet the production needs of enterprises, and are not conducive to development and promotion. Enterprises generally use strong light to illuminate silk cocoons to identify internal contaminated cocoons with human eyes, and this method has certain problems. Long-term direct exposure to strong light can easily lead to decreased vision and reduced discrimination ability; long-term high-intensity use of the eyes can easily fatigue the human eye and increase the discrimination error; the discrimination of light transmittance is greatly affected by human subjective factors. Automatic sorting of silk cocoons can, to a certain extent, realize the sorting of internal contaminated cocoons, reduce the labor intensity of workers, reduce the production costs of enterprises, and improve the production efficiency of enterprises.

[0004] Existing sorting devices generally use manipulators as actuators. However, the elastic modulus and other properties of silk cocoons from different regions and varieties are different, and it is difficult to control the clamping force of the manipulator, which can easily lead to irreversible deformation of the silk cocoons. In addition, the control is complex and it is difficult to sort multiple internally contaminated cocoons at the same time. Therefore, in order to solve the above problems, a device for sorting internally contaminated cocoons is proposed. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide an internally contaminated cocoon sorting device that can quickly, accurately and easily separate internally contaminated cocoons without cutting the cocoons, so as to realize the transition from manual cocoon selection to machine cocoon selection and promote the high-quality development of the mulberry silk industry.

[0006] To achieve the above object, the present invention proposes the following solution:

[0007] The invention discloses an internally contaminated cocoon sorting device, comprising a cocoon peeling and discharging mechanism, a differential shunt mechanism, an intelligent detection mechanism, a sorting actuator, a cocoon collecting box and an aluminum frame; the differential shunt mechanism is fixed in the aluminum frame, the cocoon peeling and discharging mechanism is fixed just above the primary conveyor belt of the differential shunt mechanism, the cocoon outlet of the cocoon peeling and discharging mechanism faces the V-shaped baffle of the differential shunt mechanism, the sorting actuator is fixedly installed on the aluminum frame on the side of the secondary conveyor belt of the differential shunt mechanism away from the primary conveyor belt, the output end of the secondary conveyor belt faces the sorting actuator, two cocoon collecting boxes are respectively placed on both sides of the sorting actuator, one is an internally contaminated cocoon collecting box, and the other is a cocoon collecting box for loading on a vehicle, and the intelligent detection mechanism is fixedly installed on the aluminum frame next to the light belt mounting frame of the differential shunt mechanism.

[0008] The cocoon peeling and cocoon discharging mechanism comprises a cocoon peeling component, a cocoon discharging component and a material discharging shell; the cocoon peeling component and the cocoon discharging component are both centered between two parallel material discharging shells in width.

[0009] The cocoon peeling assembly comprises a cocoon peeling drum, a cocoon peeling belt, a cocoon peeling roller and a cocoon peeling baffle; the cocoon peeling belt is made of chlorofiber cloth, which has a strong adsorption force on the cocoon skin; the cocoon peeling roller is a steel pipe wrapped with rubber, which can effectively avoid the damage of the cocoon pupa caused by collision; the cocoon peeling drums are respectively installed in the two ends of the cocoon peeling belt, and the cocoon peeling rollers are installed on the lower side of the cocoon peeling belt, and the cocoon peeling baffle is arranged at intervals; the cocoon peeling baffle is perpendicular to the cocoon peeling belt, and the interval is slightly larger than the short axis diameter of the ordinary silk cocoon; the cocoon peeling roller is connected to the motor through a coupling, and the cocoon peeling roller and the gear are coaxially fixedly connected. The two gears rotate at the same speed, and the two gears mesh with each other for transmission. The cocoon peeling roller coaxially connected to the other gear rotates accordingly, driving the cocoon peeling belt to rotate; the cocoon peeling roller and the cocoon peeling belt move relative to each other, clamping the outer layer of the cocoon. At this time, the cocoon is dynamically balanced on the cocoon peeling belt due to the influence of multiple forces such as the cocoon's own gravity, the supporting force of the cocoon peeling belt, the friction force of the cocoon peeling roller, the tension of the cocoon skin, and the thrust of the cocoon behind. As the cocoon skin is drawn into the gap between the cocoon peeling roller and the cocoon peeling belt, the tension of the cocoon skin increases, thereby stripping off the remaining cocoon skin of the cocoon, and the stripped cocoon skin adheres to the cocoon peeling belt.

[0010] The cocoon discharge assembly comprises a cocoon discharge drum and a cocoon discharge shell; the outer wall of the cocoon discharge drum is evenly provided with a plurality of U-shaped grooves arranged at intervals along the circumference, the mouth width and mouth depth of the U-shaped grooves are slightly larger than the short axis diameter of a single silk cocoon, and the cross section of the U-shaped grooves can just place a single silk cocoon horizontally; the cocoon discharge shell is respectively provided with a cocoon inlet and a cocoon outlet at the top and bottom, and the light cocoon after being stripped by the cocoon peeling assembly falls into the U-shaped groove of the cocoon discharge drum under the push of the hairy cocoon behind, and is driven by the cocoon discharge drum to rotate in the cocoon discharge shell, and then the silk cocoon falls from the cocoon outlet below the cocoon discharge shell to the primary conveyor belt of the differential diversion mechanism in a non-overlapping state under the action of gravity.

[0011] The differential shunt mechanism includes a primary conveyor belt, a V-shaped baffle, a screw shunt assembly, an LED light strip, a light strip mounting frame, a secondary conveyor belt, a synchronous wheel, a synchronous belt, a motor and a motor mounting frame; the front and rear widths of the V-shaped baffle are centered above the primary conveyor belt, and are made of black opaque frosted material, and the bottom width is greater than the maximum size of a single cocoon and less than the sum of the minimum sizes of two cocoons; the front and rear widths of the light strip mounting frame are centered above the secondary conveyor belt, and the distance between the two light strip mounting frames is the maximum minor axis diameter of a single cocoon, ensuring that light penetrates the cocoon without affecting the transmission of the cocoon.

[0012] The screw diversion assembly includes a photoelectric sensor, a screw, a screw nut, a cocoon pushing plate, a coupling, a motor, a bearing, a cocoon blocking plate and a diversion baffle; the motor output shaft is installed with a screw through a coupling, and the screw nut is coaxially connected to the screw, and the screw nut is fixed with a cocoon pushing plate close to the primary conveyor belt; the diversion baffle is centrally installed on the primary conveyor belt next to the V-shaped baffle; the photoelectric sensor is fixedly installed on the cocoon blocking plate, and when the photoelectric sensor stably obtains the signal of the approaching cocoon, the motor drives the screw to rotate, the screw nut moves back and forth along the screw, and the cocoon pushing plate fixed on the screw nut pushes the cocoon to move, thereby realizing the diversion of the cocoon.

[0013] The intelligent detection mechanism includes an industrial camera, a black box and a host computer; the industrial camera is installed in the middle of the top of the black box to collect images of cocoons, upload the collected images to the host computer, and judge whether the inside of the cocoon is contaminated by the light transmittance of the cocoon layer, and determine the position of the cocoon. The lower computer calculates the running direction and minimum running speed of the sorting actuator according to the state and position information of the cocoon and the running speed of the transmission mechanism.

[0014] The sorting actuator comprises a cocoon sorting platform, a hexagonal coupling, a motor and a cocoon collecting box; the cocoon sorting platform is fixedly mounted on the hexagonal coupling, the output shaft of the motor is coaxially fixedly connected to the hexagonal coupling, and when the motor rotates, the cocoon sorting platform fixedly connected to the hexagonal coupling is driven to rotate in a directional manner, thereby realizing the sorting of cocoons.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The present invention is provided with a cocoon peeling component and a cocoon discharging component. The cocoon peeling component is mainly composed of a cocoon peeling belt and a cocoon peeling roller. The cocoon skins are separated by the relative movement of the cocoon peeling belt and the cocoon peeling roller. The cocoon discharging component is mainly composed of a cocoon discharging drum and a cocoon discharging shell. The cocoon discharging drum drives the cocoons to rotate in the cocoon discharging shell. Then, under the action of gravity, the cocoons fall from the cocoon outlet below the cocoon discharging shell to the primary conveyor belt of the differential diversion mechanism in a non-overlapping state. With the help of the differential conveyor belt, the recognition error caused by the adhesion and stacking of cocoons is avoided, and the accuracy of identifying the internally contaminated cocoons is improved.

[0017] 2. The present invention utilizes photoelectric technology to analyze the light transmittance of the cocoon layer of silkworm cocoons. Without opening the cocoons, the present invention selects the cocoons with no obvious surface features but the internal cocoon layer has been contaminated, such as the inner printed cocoons and the bleeding pupa cocoons, so as to reduce the decrease in silk quality and output caused by the mixing of internally contaminated cocoons into the cocoons on the train, thereby improving the quality of silk reeling in the enterprise.

The silk cocoons 7 are poured into the cocoon peeling and cocoon discharging mechanism 1, and enter the differential diversion mechanism 2 after being peeled and arranged by the cocoon peeling and cocoon discharging mechanism 1. During the transmission process of the differential diversion mechanism 2, the intelligent detection mechanism 3 uploads the collected image to the upper computer and determines whether the inside of the cocoon is contaminated according to the light transmittance of the cocoon layer, and communicates the status and position information of the cocoon to the lower computer. The lower computer controls multiple control and sorting execution mechanisms 4 to sort the cocoons 7 according to the status and position information of the cocoons and the running speed of the secondary conveyor belt 212.

[0030] The intelligent detection mechanism 3 includes an industrial camera 21, a black box 22 and a host computer; the industrial camera 21 is installed in the middle of the top of the black box 22, and uses photoelectric technology to collect images of silk cocoons, uploads the collected images to the host computer, and judges whether the inside of the silk cocoon 7 is contaminated by the light transmittance of the cocoon layer, and determines the position of the silk cocoon 7.

[0031] like Figure 2 and Figure 3 As shown, the cocoon peeling and discharging mechanism 1 comprises a cocoon peeling assembly, a cocoon discharging assembly and a material discharging shell 110 ; the widths of the cocoon peeling assembly and the cocoon discharging assembly are both centered between two parallel material discharging shells 110 .

[0032] The cocoon peeling assembly includes a cocoon peeling drum 11, a cocoon peeling belt 12, a cocoon peeling roller 13 and a cocoon peeling baffle 111; the cocoon peeling belt 12 is made of chlorofiber cloth, which has a strong adsorption force on the cocoon skin; the cocoon peeling roller 13 is a steel pipe wrapped with rubber, which can effectively avoid the damage of the cocoon pupa caused by collision; the cocoon peeling drum 11 is installed at both ends of the cocoon peeling belt 12, and the cocoon peeling roller 13 is installed on the side and lower part of the cocoon peeling belt 12, and the cocoon peeling belt 12 and the cocoon peeling roller 13 are arranged at intervals; the cocoon peeling baffle 111 is perpendicular to the cocoon peeling belt 12, and the interval is slightly larger than the short axis diameter of the ordinary silk cocoon; the cocoon peeling roller 13 is connected to the motor 16 through a coupling 15, and the cocoon peeling roller 13 and the gear 14 are coaxially fixedly connected.

At this time, the cocoon 7 is subjected to the effects of multiple forces such as the gravity of the cocoon 7 itself, the supporting force of the cocoon peeling belt 12, the friction force of the cocoon peeling roller 13, the pulling force of the cocoon coat, and the thrust of the cocoon behind, and is dynamically balanced on the cocoon peeling belt 12. As the cocoon coat is drawn into the gap between the cocoon peeling belt 12 and the cocoon peeling roller 13, the pulling force of the cocoon coat increases, thereby stripping off the remaining cocoon coat of the cocoon 7, and the stripped cocoon coat adheres to the cocoon peeling belt 12 to achieve the stripping of the cocoon coat.

[0033] The cocoon discharge assembly includes a cocoon discharge drum 18 and a cocoon discharge shell 19; the outer wall of the cocoon discharge drum 18 is evenly provided with a plurality of U-shaped grooves arranged at intervals along the circumference, the width and depth of the U-shaped grooves are slightly larger than the short axis diameter of a single cocoon 7, and the cross-section of the U-shaped groove can just place a single cocoon 7 horizontally; the cocoon discharge shell 19 is respectively provided with a cocoon inlet and a cocoon outlet at the top and bottom, and the cocoons 7 after being peeled off the cocoon assembly fall into the U-shaped groove of the cocoon discharge drum 18, and are driven by the cocoon discharge drum 18 to rotate in the cocoon discharge shell 19, and then fall from the cocoon outlet below the cocoon discharge shell 19 to the primary conveyor belt 21 of the differential diversion mechanism 2.

[0034] like Figure 4 and Figure 5As shown, the differential shunt mechanism 2 includes a primary conveyor belt 21, a V-shaped baffle 26, a screw shunt assembly, an LED light strip 210, a light strip mounting bracket 211, a secondary conveyor belt 212, a synchronous wheel 213 and a synchronous belt 214; the V-shaped baffle 26 is centered on the primary conveyor belt 21 in terms of front and rear widths, and is made of black opaque frosted material, with a bottom width greater than the maximum size of a single cocoon and less than the sum of the minimum sizes of two cocoons 7; the light strip mounting bracket 211 is centered on the secondary conveyor belt 212 in terms of left and right widths, and the distance between each channel of the light strip mounting bracket 211 is the maximum minor axis diameter of a single cocoon 7, thereby ensuring that light penetrates the cocoon 7 without affecting the transmission of the cocoon.

[0035] like Figure 6 As shown, the screw diversion assembly includes a photoelectric sensor 22, a screw 24, a screw nut 25, a cocoon pushing plate 27, a coupling 15, a motor 16, a bearing 17, a cocoon blocking plate 28 and a diversion baffle 29; the output shaft of the motor 16 is installed with a screw 24 through the coupling 15, and the screw nut 25 is coaxially connected to the screw 24, and the screw nut 25 is fixed with a cocoon pushing plate 27 close to the conveyor belt direction; the diversion baffle 29 is centrally installed on the secondary conveyor belt 212 next to the light belt mounting frame 211; the photoelectric sensor 22 is fixedly installed on the cocoon blocking plate 28, and when the photoelectric sensor 22 stably obtains the signal that the cocoon is approaching, the motor 16 drives the screw 24 to rotate, the screw nut 25 moves back and forth along the screw 24, and the cocoon pushing plate 27 fixed on the screw nut 25 pushes the cocoon 7 to move, thereby realizing the cocoon diversion.

When the motor 16 rotates, the cocoon sorting platform 41 fixedly connected to the hexagonal coupling 42 is driven to rotate in a directional manner, so that the cocoons 7 roll down from both sides of the cocoon sorting platform 41 to the corresponding cocoon collecting box 5. The lower computer calculates the running direction and the minimum running speed of each cocoon sorting platform 41 according to the state and position information of the cocoon 7 and the running speed of the secondary conveyor belt 212. When the cocoon 7 moves to the end of the differential shunt mechanism 2, the cocoon 7 falls from the differential shunt mechanism 2 and lands on the sorting actuator 4 of the current channel; if the current cocoon 7 is in the same state as the previous cocoon 7, both are loading cocoons, the cocoon sorting platform 41 remains stationary, and the cocoon 7 falls into the loading cocoon collecting box 52 along the inclined direction of the cocoon sorting platform 41; if it is different from the previous cocoon 7, that is, it is an internally contaminated cocoon, the cocoon sorting platform 41 rotates to the other side, and the cocoon 7 falls into the internally contaminated cocoon collecting box 51.
