Description

TECHNICAL FIELD

[0001] The present application relates to the field of silkworm breeding equipment, in particular to a silkworm cocoon picking work line. BACKGROUND

[0002] Silk is a continuous long fiber formed by the secretion of mature silkworms, also known as natural silk, which is a natural fiber with a wide range of uses, such as quilts, clothing, cosmetics, and health products. In the field of quilts and clothing products, silk is a very light natural fiber that can deform within a certain range without damage when subjected to external forces, and can return to its original state after the external force is removed, with the properties of not clumping, not smelly, and uniform softness. In addition, the breathability and moisture permeability of silk make silk products feel smooth and comfortable. Based on the many advantages of silk products, the scale of silkworm breeding for producing silk has also been expanding rapidly. Under such a rapid development trend, the original conventional manual feeding, disc changing, and silk extraction breeding methods have obviously become incompatible, so various automated high-efficiency auxiliary breeding equipment has appeared in the field of silkworm breeding, greatly improving the work efficiency at each stage and reducing production costs.

[0003] In the process of silkworm breeding, separating the cocoon from the cocoon tray is a very labor-intensive process that requires both high efficiency and the prevention of damage to the cocoon, so various devices have been developed to efficiently and automatically collect mature cocoons.

[0004] As disclosed in the Chinese patent application No. CN201710935085.6, a device for large-scale breeding of silkworms includes a frame, a breeding bed including a cocoon frame and a bottom plate, a first rotating shaft installed on the underside of the bottom plate, the cocoon frame vertically arranged on the upper side of the bottom plate along the length direction of the bottom plate, the cocoon frame composed of staggered vertical rods and horizontal rods, a mulberry leaf conveying mechanism including a conveying belt and a second rotating shaft, the conveying belt installed on the second rotating shaft, the conveying belt horizontally rotating to convey mulberry leaves, the second rotating shaft axially rotating to make the conveying belt turn upside down to dump mulberry leaves, a cocoon picking mechanism including a guide rail and a cocoon comb, the upper part of the cocoon comb nested into the guide rail, the lower part extending to the breeding bed, the cocoon comb sliding along the guide rail to scrape off the cocoon on the breeding bed, and a collection tank.

[0005] For example, the automatic collection of cocoon mulberry silkworm breeding device disclosed in the Chinese patent application No. CN201710935083.7, comprising: a rack; a breeding bed; a mulberry leaf conveying mechanism, which includes a conveying belt and a second rotating shaft, the second driving mechanism drives the conveying belt to rotate to transport the mulberry leaves horizontally, the second rotating shaft is connected with the third driving mechanism, and the third driving mechanism drives the axial rotation of the second rotating shaft to make the conveying belt overturn to dump the mulberry leaves downward; a cocoon picking mechanism; and a collection mechanism, including a collection groove and a blower, the slot of the collection groove is provided with a groove cover plate to close the slot, and the blower is arranged at any one end of the collection groove to supply air to the inside of the collection groove; wherein the two sides of the groove cover plate are provided with second guide rails, and the groove cover plate is slidingly fitted to the slot to open and close the slot.

[0006] In the foregoing mulberry silkworm breeding device used in the mulberry silkworm breeding process, although the mulberry leaf residues and excrement in the breeding process can be treated, and the separated cocoon can be made to fall by gravity, the breeding device under this structure cannot be applied to the large-scale and streamlined production processing line which needs to separate the cocoon tray from each processing equipment according to different stages.

[0007] For example, the automatic cocoon picking device disclosed in the Chinese patent application No. CN201920616609.X, comprising a secondary conveyor, a primary conveyor, a hollow cuboid component and a square grid cluster; the secondary conveyor is connected with the primary conveyor through a synchronous belt, one end of the primary conveyor extends into the inside of the hollow cuboid component through the middle position of the front end face of the hollow cuboid component, a connecting rod is fixed at the top end of the hollow cuboid component, the other end of the connecting rod is fixedly connected with a guide rail, the guide rail is located directly above the edge of the primary conveyor, a stepping motor is arranged directly below the guide rail, a reversed "T" structure is connected below the stepping motor, a silk cutting device is connected at one end of the reversed "T" structure inside the primary conveyor, and a push rod is connected at the other end.

[0008] In the automatic cocoon picking device, although the cocoon is separated from the tray by cutting in the vertical direction, there will still be some cocoon with silk connected to the tray on the outer surface after the one-way cutting process, which will lead to insufficient cocoon picking and reduce the cocoon picking efficiency.

[0009] In summary, the existing devices and the processing line formed by combining them for picking cocoon cannot realize large-scale automatic and efficient picking operation while maintaining low damage to the cocoon on the cocoon tray and low loss of silk.

[0010] In view of the above problems, the present application provides a silkworm cocoon picking work line suitable for large-scale automated efficient picking of silkworm cocoons and capable of achieving effective protection of silkworm cocoons and silk. SUMMARY

[0076] The following specific embodiments are only an explanation of the present application, which is not a limitation of the present application, and those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.

[0077] The present scheme is realized through the following technical means:

[0078] Example 1: In this embodiment, a main structure form of the mulberry silkworm cocoon C1 picking line is given. The mulberry silkworm cocoon C1 picking line mainly comprises two parts of cocoon overturning treatment system A and cocoon-cocoon tray automatic separation equipment B arranged in sequence.

[0079] First, in the present embodiment, need to contain in the mulberry silkworm cocoon C1 picking work line of a special cocoon tray C structure is simply introduced. Referring to the attached Figure 18 and attached Figure 19 , the bottom edge of the cocoon tray C is supported on the top of the positioning member, and the cocoon tray C has uniformly distributed and vertically penetrating openings, and the edges of the penetrating openings are provided with a plurality of vertical cocooning columns. By utilizing the upward climbing characteristics of silkworms, the silkworms climb from the bottom of the block breeding plate to the cocoon tray C, climb onto the cocoon tray C after passing through the penetrating openings, and form cocoons C1 between adjacent cocooning columns. As an example of the attached drawings, the cocooning columns above the cocooning grid form a square grid, and the resulting cocoons C1 are all located in the square grid receiving area.

[0080] The cocoon turning processing system A is the front part of the mulberry silkworm cocoon C1 picking work line, and mainly plays the role of turning and inverting the cocoon tray C with cocoon C1 on it arranged in a forward flat manner, so as to facilitate the stripping and collection of cocoon C1 relative to the cocoon tray C. The system comprises, from front to back, a feeding conveying moving unit Aa, a tray turning assembly Ac and a discharging conveying moving unit Ab. The feeding conveying moving unit Aa and the discharging conveying moving unit Ab are the same in structure, but are distinguished by name due to their different relative positions and different actual functions.

[0081] Specifically, taking the feeding conveying moving unit Aa as an example, it is a roller conveyor belt type structure, mainly comprising a pair of synchronous rollers rotating at the same speed at the front and rear ends, and a conveyor belt is arranged around the synchronous rollers. It should be noted that the two ends of the synchronous roller are in the form of a large-diameter cylinder and are connected together by a connecting shaft at the center, and two rubber conveyor belts are arranged on the same side of the two rollers, so that a hollow avoidance area A4 is formed on the feeding conveying moving unit Aa. Corresponding to the feeding conveying moving unit Aa, the two sides of the cocoon tray C comprise a matching connecting part A3b protruding to the two sides, so that it can be erected between the two conveyor belts. Due to the existence of the hollow avoidance area A4, whether the cocoon tray C is placed in a forward direction or inverted, the cocooning column part protruding upward and the cocoon C1 connected to the cocooning column will not contact the conveyor belt, effectively avoiding damage to the cocoon C1 and the cocoon C1 falling off relative to the cocoon tray C during conveying. Since the feeding conveying moving unit Aa and the discharging conveying moving unit Ab are similar in structure, it is only necessary to note that the moving directions of the conveyor belts on the two units are the same, so no further description is given here.

[0082] As the most critical part of the cocoon turning processing system A, the tray turning assembly Ac is located between the aforementioned feeding conveying moving unit Aa and discharging conveying moving unit Ab, and is connected with the two units. Specifically, the tray turning assembly Ac comprises a tray turning frame A1 capable of rotating around a horizontal fixed center axis and an intermittent rotary driving device A2 for driving the tray turning frame A1 to rotate.

[0083] The embodiment is attached Figure 4 As an example of the structure, the tray turning frame A1 is a component with two cross-shaped fork structures connected by a connecting shaft at the intersection center of the two cross-shaped fork structures. The tray turning frame A1 is rotatably installed on the lower support rack Ae and can rotate around the fixed center axis. On the side of the tray turning frame A1, the intermittent rotary driving device A2 is connected and installed. Specifically, the intermittent rotary driving device A2 comprises a driving motor and a control module. The output shaft of the driving motor is connected to the tray turning frame A1 through a shaft coupling, and the control module can realize the power output of the driving motor at intervals, so as to realize the continuous stop-rotation alternating operation.

[0084] The tray turning frame A1 extends outwardly and protrudes to form a clamping connection part A3a for connecting with the cocoon tray C. With the vertical plane of the center axis of the tray turning frame A1 as a boundary, the turning process is divided into two independent stages. The clamping connection part A3a comprises a first supporting surface A301 for supporting the cocoon tray C during the previous turning stage, and a second supporting surface A302 for supporting the cocoon tray C during the subsequent turning stage. The clamping connection part A3a is connected with the matching connection part A3b by insertion. In the tray turning frame A1 of the embodiment, each supporting arm formed by the rotation center extending outwardly on the cross-shaped fork structure is a clamping connection part A3a. That is, four clamping connection parts A3a are formed around the center line of the cross-shaped fork structure, and adjacent two clamping connection parts A3a are perpendicular to each other. At this time, the clamping connection part A3a on the tray turning frame A1 and the matching connection part A3b on the cocoon tray C form an active clamping structure A3.

[0085] Specifically, in the tray turnover frame A1 with the cross-shaped fork structure, one of the clamping connection portions A3a can be formed by a pair of parallel metal rods, and the first and second bearing surfaces A301 and A302 are located on the long slot extending inwardly at the position between the two metal rods. It should be noted that the width of the long slot is slightly larger than the thickness of the matching connection portion A3b formed on the tray C, so that the clamping connection portion A3a and the matching connection portion A3b can be inserted into each other and still have a space A303 for the tray C to swing. That is, when the tray C enters the tray turnover frame A1 under the action of the conveying belt, the matching connection portion A3b slides into the long slot, but the tray C is not completely clamped and fixed, and can swing within a certain angle range.

[0086] In this structure, when the tray C in the normal flat state is placed in the feeding conveying unit, the matching connection portion A3b will gradually enter the clamping connection portion A3a on the tray turnover frame A1 as the conveying belt moves forward, until the front end thereof abuts against the bottom of the long slot and cannot continue to advance. It should be noted that at this time, the center of gravity of the tray turnover frame A1 is still located outside the long slot. At this time, under the action of the control module, the driving motor drives the tray turnover frame A1 to rotate, and due to the action of the clamping connection portion A3a on the matching connection portion A3b, one side of the tray C will be lifted upward first to form an inclined state. At this time, the upper surface of the front end of the tray C abuts against and fits the second bearing surface A302 located above the slot of the tray C, and the local part close to the middle abuts against and fits the first bearing surface A301 located below the slot of the tray C, that is, the tray C is lifted upward in a manner from the local part to the whole with the movement of the tray turnover frame A1. During the lifting process, the tray C receives less impact, which can effectively prevent the cocoon C1 from falling off.

[0087] With the continuous rotation of the tray turnover frame A1, the cocoon tray C will be rotated to a position beyond the central axis of the tray turnover frame A1. At this time, due to the fact that the aforementioned long slot is slightly wider than the matching connecting part A3b, under the action of gravity, the cocoon tray C will be inclined to the other side. At this time, the cocoon tray C is engaged with the tray turnover frame A1 in a state opposite to the previous turning stage. Specifically, at this time, the aforementioned second supporting surface A302 is located below to play a supporting role, while the first supporting surface A301 is located above to play a supporting role. It should be noted that the contact surface between the cocoon tray C and the tray turnover frame A1 needs to have sufficient friction to prevent the cocoon tray C from slipping out and falling relative to the tray turnover frame A1 when it is not lifted.

[0088] With the continuous rotation of the tray turnover frame A1, the outer end of the cocoon tray C, which has completed the overall turning and inversion, will gradually contact the upper surface of the conveying belt on the rear discharge conveying unit. Under the action of the movement of the conveying belt and the rotation of the tray turnover frame A1, the contact surface between the cocoon tray C and the conveying belt gradually increases, and the cocoon tray C gradually moves outward under the action of friction, separates from the tray turnover frame A1, and completes the overall turning action. Since the separation process of the cocoon tray C is also a gradual process, the impact and vibration effect transmitted to the cocoon tray C is also small, thereby protecting the cocoon C1.

[0089] With the continuous operation of the rear discharge conveying unit, the cocoon tray C will continue to move backward to the cocoon-cocoon tray automatic separation device B.

[0090] In the cocoon-cocoon tray automatic separation device B, first contains a support frame B1 which can be divided into three layers from top to bottom, the support frame B1 as a whole can be connected and fixed by welding with several steel pipe parts. Among the three layers of the support frame B1, the middle layer forms a mounting block B2 as a supporting part of the cocoon tray C. The cocoon tray C here is placed in an inverted state with the cocooning column extending downward after the turning process, and is moved into the mounting block B2 of the support frame B1 under the pushing of the aforementioned discharge conveying unit. At this time, the two sides of the cocoon tray C are located at the upper edge position of the mounting block B2.

[0091] In the uppermost layer of the support frame B1, a vertical separation assembly B3 is installed, which can push and extrude the cocoon C1 on the cocoon tray C to make the cocoon C1 move along the vertical direction by moving the components of the vertical separation assembly B3. Specifically, the vertical separation assembly B3 includes a support plate B3a that can move up and down along the vertical direction. The support plate B3a is formed with a plurality of support columns B301 that protrude downward and can pass through the hollow cocoon area on the cocoon tray C. The upper part of the vertical separation assembly B3 is installed with a reciprocating piston cylinder as a driving assembly B7. The output end of the cylinder extends downward and is connected and fixed to the upper surface of the support plate B3a. In the lowermost layer of the support frame B1, a cocoon collecting device B5 is fixedly installed with an opening upward. When the output end of the cylinder moves along the vertical direction, the support plate B3a can also move up and down along the vertical direction, and each support column B301 can extend into a corresponding hollow grid area. At this time, for a hollow cocoon area, the lower surface of the support column B301 will gradually abut against a cocoon C1 body in a lump shape. As the support column B301 moves downward, it will continue to push the cocoon C1 body downward to make the cocoon C1 body fall off and separate from the cocoon tray C and enter the cocoon collecting device B5.

[0092] However, in this process, the silk C2 connected between the cocoon C1 body and the cocoon tray C has a certain elasticity, and the silkworm has a certain amount of silk C2 when it is connected to the cocoon tray C. That is, after the cocoon C1 body is completely pushed out of the grid-shaped cocoon area by the support column B301, part of the silk C2 will still be connected between the cocoon C1 and the cocoon tray C after displacement or stretching. At this time, two situations will occur. First, the cocoon C1 body hangs below the cocoon tray C, which cannot be fully separated from the cocoon tray C, greatly reducing the cocoon C1 harvest rate. Second, the cocoon C1 body falls into the cocoon collecting device B5, but the silk C2 on the surface is still connected to the cocoon tray C. At this time, if the cocoon tray C is moved relative to the cocoon collecting device B5, the cocoon C1 that has been collected will be pulled, causing part of the silk C2 to be damaged or to fall out of the cocoon collecting device B5, which can also cause the length of the cocoon C1 to increase, increasing the loss of silk C2.

[0093] Based on the above problems, the cocoon-cocoon tray automatic separation equipment B given in this embodiment, on the basis of the original equipment, a set of horizontal separation assembly B4 is set up, which can separate the silk C2 connected between the cocoon tray C and the cocoon C1 body by moving the components in the horizontal direction. The horizontal separation assembly B4 uses a cutting unit B4a to realize the cutting of the local silk C2. Specifically, the cutting unit B4a contains a cutter head B401 for cutting silk C2 and a first translation mechanism B402 for driving the cutter head B401 to move horizontally. The cutting edge of the cutter used on the cutter head B401 extends horizontally. The cutter head B401 can be installed on the erected block B2 in the middle position of the support frame B1. Of course, it can also work in the way of installing an external support frame independent of the support frame B1. It only needs to ensure that the cutter head B401 can move back and forth along the fixed track on the plane slightly lower than the lower surface height of the erected cocoon tray C. The first translation mechanism B402 can use a tow chain device. By fixing the output end of the tow chain device and the cutter head B401, the cutter head B401 can be accurately controlled in speed, range and other related parameters under the control of the tow chain device.

[0094] After the vertical separation assembly B3 pushes the cocoon C1 body downward, the tow chain device will start to work, driving the cutter head B401 to move and cut off all the silk C2 still connected between the cocoon C1 and the cocoon tray C, ensuring that the cocoon C1 falls completely into the cocoon collection device B5 relative to the cocoon tray C.

[0095] In order to avoid the situation that the cocoon tray C slips out or is thrown out when the cocoon tray C is connected to the tray turnover frame A1 in a certain relatively fast operation mode, the structure of the cocoon tray turnover system A is adjusted and improved in this embodiment based on the cocoon picking work line given in Embodiment 1. A limiting connection structure A5 is formed on the tray turnover frame A1 to realize the connection between the tray turnover frame A1 and the cocoon tray C during the turnover process. Specifically, the limiting connection structure A5 includes grooves formed on the first supporting surface A301 and the second supporting surface A302, and upward and downward extending protruding parts formed on the end part of the matching connection part A3b. No matter whether the cocoon tray C is in the first turnover stage or the second turnover stage, the part close to the bottom of the long slot is upwardly curved, so that the protruding part is embedded in the groove to form a mutual clamping state. The limiting connection structure A5 can provide a force directed to the center of rotation for the cocoon tray C during the rotation process, thereby effectively avoiding the cocoon tray C from being thrown out and improving the safety of the turnover action. In addition, the limiting connection structure A5 has the effect of automatically completing the clamping connection between the two parts under the action of gravity in different turnover stages, without the need for additional control modules or components, which is very stable and efficient.

[0096] Further preferably, a buffer part is formed on the tray turnover frame A1 to reduce the collision vibration generated during the connection between the tray turnover frame A1 and the cocoon tray C. For example, in this embodiment, a flexible pad layer made of rubber or foam material can be installed on the bottom of the long slot and the connecting shaft between the two cross-shaped fork-shaped members on the tray turnover frame A1 to reduce the vibration and collision generated during the connection between the cocoon tray C and the tray turnover frame A1, and to avoid the cocoon C1 from falling off relative to the tray.

[0097] In this embodiment, the structure of the tray turnover frame A1 adopts a cross shape. Of course, according to different work line operation speeds and the structure and shape of the cocoon tray C, other similar structures can also be arranged uniformly around the center axis, such as a herringbone shape. As for the clamping connection structure, in the specific implementation given in this embodiment, the protruding part is arranged on the cocoon tray C and the corresponding slot part is arranged on the tray turnover frame A1. As an alternative to this structure, it is easy to think that the positions of the two parts are interchanged, and of course, a similar movable clamping structure A3 with the above functions can also be formed.

[0098] In this embodiment, based on the foregoing embodiment 1 or embodiment 2, the structure of the rear part of the automatic cocoon separation device B in the cocoon C1 picking work line is optimized and improved.

[0099] Specifically, referring to the automatic cocoon picking device disclosed in the Chinese patent document cited in the background of the present application, a plurality of downwardly oriented blades B302 can be arranged at the lower end of the support column B301, the arrangement of the blades B302 corresponds to the hollow area on the cocoon tray C, and a gap is formed between the blades B302 and the cocoon tray C. Through the improved structure, the blades B302 can cut the cocoon C1 body around the cocoon C1 body before the bottom end of the support column B301 contacts the cocoon C1 body, thereby reducing the amount of silk C2 pulled apart in the process of breaking and improving the separation effect.

[0100] Further, in order to improve the accuracy of the vertical movement of the guide support column B301 and avoid collision with the cocoon tray C, a guide assembly B6 is arranged between the support plate B3a and the support frame B1 for guiding the vertical movement of the support plate B3a. Specifically, the guide assembly B6 includes two guide sleeves fixed to the support frame B1 and two guide columns corresponding to the guide sleeves fixed to the cocoon tray C. One guide sleeve and one guide column can be inserted into each other to form a combined assembly that can extend and retract. Two pairs of combined assemblies are arranged on both sides of the drive assembly B7 to ensure that the support plate B3a is always in a horizontal state during the lifting movement.

[0101] In this embodiment, as another implementation form of the automatic cocoon separation device B, the structure of the horizontal separation assembly B4 can be adjusted and replaced. Specifically, in this embodiment, the horizontal separation assembly B4 includes a fusing unit B4b, which includes a fusing portion B403 for cutting the silk C2 and a second translation mechanism B404 for driving the fusing portion B403 to move horizontally. The fusing portion B403 can be an electric heating wire component. When the high-temperature electric heating wire contacts the silk C2, the silk C2 is ablated and fused, thereby achieving complete separation between the cocoon C1 and the cocoon C1 tray. Similar to embodiment 1, the second translation mechanism B404 can also be a drag chain device, which will not be described here.

[0102] In this embodiment, the structure of the transverse separation assembly B4 of the foregoing embodiment 1 and embodiment 4 is combined, so that the cocoon picking work line in this embodiment gives the cocoon-cocooning tray automatic separation device B the advantages of both the cutting-off type separation unit and the fuse type separation unit.

[0103] Specifically, two parts of guide rails are arranged on the support frame B1 in this embodiment, the cutting-off unit B4a and the fuse unit B4b in the transverse separation assembly B4 are arranged on the erection block B2 on the support frame B1, and the two units are respectively driven by different sets of drag chain devices, but it should be noted that the two units should be arranged at different heights to avoid mutual interference during work. Taking the upper one as the cutting unit and the lower one as the fuse unit B4b as an example, when the vertical separation assembly B3 pushes the cocoon C1 body downward relative to the cocooning tray C, a part of the cocoon C1 body is still connected to the cocooning tray C through the silk C2. At this time, the drag chain device as the first translation mechanism B402 drives the cutter head B401 to translate and cut the silk C2, but for some cocoon C1 whose movement stroke range is behind the cutter head B401 or whose silk C2 is stretched a lot, the translation movement of the cutter head B401 obviously cannot cut the silk C2 connecting the cocoon C1 and the cocooning tray C; therefore, in the second stage, another set of drag chain devices as the second translation mechanism B404 drive the fuse part B403 containing high-temperature electric heating wire to move, and completely cut the part of the silk C2 still connected by ablation.

[0104] The cocoon-cocooning tray automatic separation device B in this embodiment not only solves the problem of cutting-off type processing, but also avoids completely cutting by the fuse type, so that ablation and damage of a large amount of silk C2 during processing is avoided, and material loss during processing is reduced.

[0105] Of course, in order to realize efficient cocoon picking processing of multiple cocooning trays C formed with cocoon C1 in sequence by using the device, a belt type conveying movement structure B8 can also be arranged on the support frame B1. The structure combines the transmission belt and the cocoon picking device, so that multiple cocooning trays C can be placed on the support frame B1 at the same time, and under the action of the continuously moving conveying belt driven by the external power assembly, the cocooning trays C are moved one by one to the lower side of the supporting tray B3a for cocoon picking processing, which has extremely high work efficiency.

[0106] A telescopic leveling mechanism B9 composed of a plurality of screw columns capable of rotating and telescoping is movably installed on each leg of the support frame B1, so that the horizontal state of the supporting tray B3a and the cocooning tray C can be maintained when the device is placed on uneven ground of different heights.

[0107] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
