Description

Technical Field

[0001] This invention relates to the field of yarn bobbin counterweight devices, and in particular to a novel modular circulating counterweight device for horizontal yarn bobbin conveying. Background Technology

[0002] Existing yarn package conveyor counterweight systems generally employ a rejection and screening counterweight method. This system selects and groups counterweight yarns based on the total packaging weight requirements and the weight of the yarn packages, creating a set of counterweight yarns that meet the weight requirements. The rejection and screening method removes counterweight yarns that do not meet the weight requirements from the conveyor line, retaining only those that do. However, this requires manual repositioning of the rejected counterweight yarns back onto the conveyor line for another round of rejection and screening, which is time-consuming and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to provide a novel modular circulating counterweight device for horizontal conveying of yarn bobbins, which aims to solve the technical problem in the prior art that requires manual placement of rejected counterweight yarns back onto the counterweight yarn conveying line to participate in the rejection and screening of counterweights again, which is time-consuming and labor-intensive.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0005] A novel modular circulating counterweight device for horizontal yarn bobbin conveying includes a yarn bobbin conveying device and a counterweight yarn conveying device arranged side by side, and a packaging conveying device located on one side of the yarn bobbin conveying device and the counterweight yarn conveying device. The yarn bobbin conveying device and the counterweight yarn conveying device convey yarn from front to back, and the packaging conveying device conveys yarn from back to front. It also includes a yarn bobbin transfer conveying device for conveying yarn bobs from the yarn bobbin conveying device to the packaging conveying device, a counterweight yarn transfer conveying device for conveying counterweight yarn from the counterweight yarn conveying device to the packaging conveying device, and a counterweight yarn return conveying device for conveying non-compliant counterweight yarn from the packaging conveying device to the counterweight yarn conveying device. The counterweight yarn return conveying device is located in front of the counterweight yarn transfer conveying device. Push-out mechanisms are provided on the side of the yarn bobbin conveying device away from the yarn bobbin transfer conveying device, the side of the counterweight yarn conveying device away from the counterweight yarn transfer conveying device, and the side of the packaging conveying device away from the counterweight yarn return conveying device.

[0006] Using the above structure, yarn packages are conveyed from front to back via a yarn package conveyor. A pushing mechanism sequentially pushes the yarn packages to a single yarn weighing device for weighing, and then pushes the weighed yarn packages onto a yarn package transfer conveyor, which then conveys them to a packaging conveyor. Counterweight yarn is conveyed from front to back via a counterweight yarn conveyor. A pushing mechanism sequentially pushes the counterweight yarn to a single yarn weighing device for weighing, and then pushes the weighed counterweight yarn onto a counterweight yarn transfer conveyor, which then conveys them to a packaging conveyor. Through permutation and combination calculations, the required counterweight yarn is selected, and the qualified counterweight yarn is conveyed forward for counterweight packaging. The pushing mechanism pushes the unqualified counterweight yarn onto a counterweight yarn return conveyor, which returns it to the counterweight yarn conveyor for the next cycle of counterweighting.

[0007] Preferably, the yarn package transfer conveyor, the counterweight yarn transfer conveyor, and the counterweight yarn return conveyor are all chain plate conveyors. The chain plate conveyor includes multiple chain plates that are spaced apart along the length of the chain plate conveyor. The yarn package or counterweight yarn is horizontally clamped between two adjacent chain plates.

[0008] With the above structure, the yarn cones and counterweight yarns can be horizontally clamped between two adjacent chain plates for conveying, avoiding the problem of easy tipping when the yarn cones are conveyed vertically. It is suitable for conveying yarn cones with smaller diameters, has stronger stability, can use a longer transfer conveying device, and has a large number of counterweight yarns participating in the arrangement and combination, resulting in high counterweight accuracy.

[0009] Preferably, the yarn bobbin conveying device, the counterweight yarn conveying device, and the packaging conveying device are all belt conveyors, and the left and right sides of the belt conveyor are respectively equipped with first limiting rails on both sides of the yarn bobbin or the counterweight yarn. The first limiting rails can limit the position of the yarn bobbin and the counterweight yarn, so as to facilitate the push-out mechanism to transfer the yarn bobbin or the counterweight yarn to the transfer conveying device.

[0010] Preferably, multiple adjustable mounting seats are installed on both sides of the belt conveyor, and the first limit rail is fixed to the mounting seats. The mounting seats allow the distance between the two mounting seats to be adjusted according to the height of the yarn package, thereby adjusting the distance between the two first limit rails and improving the versatility of the belt conveyor.

[0011] Preferably, the mounting base has an oblong hole, and the belt conveyor has a threaded hole that matches the oblong hole. The mounting base is locked to the belt conveyor by the fit between the oblong hole and the threaded hole, and by a bolt passing through the oblong hole and screwed into the threaded hole, allowing the position of the mounting base to be adjusted left and right.

[0012] Preferably, the feeding end of the chain conveyor is provided with a feeding plate facing the feeding direction and inclined downwards. When the yarn cones or counterweight yarns are conveyed to the feeding end by the chain conveyor, the chain plate is inclined downwards, and the yarn cones or counterweight yarns on the chain plate roll onto the feeding plate, and then roll onto the packaging conveying device through the inclined feeding plate.

[0013] Preferably, a roller is rotatably mounted on the feeding end of the feed plate. The roller facilitates the rolling of the yarn package or counterweight yarn from the chain plate onto the feed plate.

[0014] Preferably, the feeding end of the chain conveyor is provided with a feeding plate that faces the discharging direction and is inclined downwards. The feeding plate facilitates the rolling of the yarn cones or counterweight yarns pushed out by the ejection mechanism onto the next conveying device.

[0015] Preferably, the feed plate is provided with second limiting rails on both the front and rear sides, which respectively limit the yarn package or the counterweight yarn on both sides. The setting of the second limiting rails limits the yarn package or counterweight yarn pushed onto the feed plate, which facilitates the conveying of the conveying device.

[0016] Preferably, two yarn package transfer conveyors are arranged at intervals along the front-to-back direction. Having two yarn package transfer conveyors improves the efficiency of yarn package transfer and packaging.

[0017] After adopting the above technical solution, the beneficial effects of the present invention are:

[0018] This invention allows non-compliant counterweight yarns to automatically return to the counterweight yarn conveyor and re-participate in the screening and weighting process. This eliminates the need for manual repositioning of rejected counterweight yarns onto the conveyor line, effectively reducing worker workload and saving time and effort. The yarn cones and counterweight yarns can be horizontally positioned between adjacent chain plates for conveying, avoiding the tipping problem associated with vertical conveying. This design is suitable for conveying yarn cones with smaller diameters, offering greater stability. It also allows for the use of longer transfer conveyor devices, enabling the arrangement and combination of a larger number of counterweight yarns with high weighting accuracy.

Detailed Implementation

[0026] The invention will now be further described with reference to the accompanying drawings.

[0027] The orientations mentioned in this specification are based on the orientation of the novel modular circulating counterweight device for horizontal conveying of yarn bobbins during normal operation. They do not limit the orientation during storage and transportation, but only represent relative positional relationships, not absolute positional relationships.

[0028] like Figures 1 to 6 As shown, a novel modular circulating counterweight device for horizontal yarn bobbin conveying includes a yarn bobbin conveying device 1 and a counterweight yarn conveying device 2 arranged side by side, and a packaging conveying device 3 located on one side of the yarn bobbin conveying device 1 and the counterweight yarn conveying device 2. The yarn bobbin conveying device 1 and the counterweight yarn conveying device 2 convey yarn from front to back, and the packaging conveying device 3 conveys yarn from back to front. It also includes a yarn bobbin transfer conveying device 4 for conveying yarn bobbins 20 from the yarn bobbin conveying device 1 to the packaging conveying device 3, a counterweight yarn transfer conveying device 5 for conveying counterweight yarn from the counterweight yarn conveying device 2 to the packaging conveying device 3, and a... Non-compliant counterweight yarn on packaging conveyor 3 is conveyed to counterweight yarn return conveyor 6 on counterweight yarn conveyor 2. Counterweight yarn return conveyor 6 is located in front of counterweight yarn transfer conveyor 5. Single yarn weighing devices 7 are provided between yarn package transfer conveyor 4 and yarn package conveyor 1, and between counterweight yarn transfer conveyor 5 and counterweight yarn conveyor 2. Pushing mechanisms are provided on the side of yarn package conveyor 1 away from yarn package transfer conveyor 4, the side of counterweight yarn conveyor 2 away from counterweight yarn transfer conveyor 5, and the side of packaging conveyor 3 away from counterweight yarn return conveyor 6. The single yarn weighing device 7 adopts the existing single yarn weighing device 7, and the pushing mechanism adopts the existing yarn package pushing mechanism.

[0029] Among them, the yarn package conveying device 1 is located to the left of the counterweight yarn conveying device 2, and the conveying length of the counterweight yarn conveying device 2 is greater than the conveying length of the yarn package conveying device 1. The packaging conveying device 3 is located to the left of the yarn package conveying device 1. The yarn package transfer conveying device 4 is vertically located between the yarn package conveying device 1 and the packaging conveying device 3. The counterweight yarn transfer conveying device 5 and the counterweight yarn return conveying device 6 are vertically located between the counterweight yarn conveying device 2 and the packaging conveying device 3.

[0030] In use, the yarn cones 20 are conveyed from front to back by the yarn cone conveyor 1. The pushing mechanism sequentially pushes the yarn cones 20 to the single yarn weighing device 7 for weighing, and then pushes the weighed yarn cones 20 onto the yarn cone transfer conveyor 4. The yarn cone transfer conveyor 4 then conveys a certain number of yarn cones 20 marked with their weight stepwise to the packaging conveyor 3. The counterweight yarn is conveyed from front to back by the counterweight yarn conveyor 2. The pushing mechanism sequentially pushes the counterweight yarn to the single yarn weighing device 7 for weighing, and then pushes the weighed counterweight yarn onto the counterweight yarn transfer conveyor 5. The counterweight yarn transfer conveyor 5 then conveys the counterweight yarn marked with its weight stepwise to the packaging conveyor 3. After permutation and combination calculations, the required counterweight yarn is selected. The counterweight yarn that meets the requirements is conveyed forward and combined with the yarn cones 20 conveyed by the yarn cone transfer conveyor 2 to the packaging conveyor 3 for counterweight packaging. The ejection mechanism pushes the non-compliant counterweight yarn onto the counterweight yarn return conveyor 6, which then returns it to the counterweight yarn conveyor 2 for the next cycle of counterweight.

[0031] This invention allows non-compliant counterweight yarns to automatically return to the counterweight yarn conveyor 2 and participate in the screening and counterweighting again, eliminating the need for manual placement of rejected counterweight yarns back onto the counterweight yarn conveyor line, effectively reducing the workload of workers and saving time and effort.

[0032] Among them, the yarn package transfer conveyor 4, the counterweight yarn transfer conveyor 5, and the counterweight yarn return conveyor 6 are all chain plate conveyors 8. The chain plate conveyor 8 includes multiple chain plates 10 that are spaced apart along the length of the chain plate conveyor 8 on the chains 9. The yarn package 20 or the counterweight yarn is horizontally clamped between two adjacent chain plates 10. The two sides of the chain plate 10 are respectively installed on two chains 9.

[0033] The yarn cone 20 and the counterweight yarn can be horizontally positioned between two adjacent chain plates 10 for conveying. The counting and detection are stable, and this stability allows for an increase in the number of chain plate 10 sections, thereby significantly increasing the number of possible arrangements and combinations, and greatly improving the counterweight accuracy. The horizontal conveying structure in this invention avoids the problem of the yarn cone 20 easily tipping over when conveyed vertically. It is suitable for conveying yarn cones 20 with smaller diameters, offers greater stability, allows for the use of longer transfer conveying devices, and enables a larger number of counterweight yarns to participate in the arrangement and combination, resulting in high counterweight accuracy.

[0034] The yarn package conveyor 1, the counterweight yarn conveyor 2, and the packaging conveyor 3 are all belt conveyors 11. Each belt conveyor 11 has a first limiting rail 12 on its left and right sides to limit the yarn package 20 or counterweight yarn. Specifically, the yarn package conveyor 1 is located to the left of the counterweight yarn conveyor 2. The first limiting rail 12 on the left side of the yarn package conveyor 1 extends to the front of the yarn package transfer conveyor 4. The first limiting rail 12 on the left side of the counterweight yarn conveyor 2 extends to the front of the counterweight yarn return conveyor 6. The packaging conveyor 3, located on the right side directly opposite the yarn package transfer conveyor 4, the counterweight yarn return conveyor 6, and the counterweight yarn transfer conveyor 5, does not have a first limiting rail 12. The first limiting rail 12 can limit the position of the yarn package 20 and the counterweight yarn, facilitating the transfer mechanism to transfer the yarn package 20 or the counterweight yarn onto the transfer conveyor.

[0035] Furthermore, multiple adjustable mounting seats 13 are installed on both sides of the belt conveyor 11, with the first limiting rail 12 fixedly connected to the mounting seat 13. The mounting seat 13 is L-shaped, and the first limiting rail 12 is welded to the mounting seat 13. The mounting seats 13 are designed to allow adjustment of the distance between the two mounting seats 13 according to the height of the yarn package 20, thereby adjusting the distance between the two first limiting rails 12 and improving the versatility of the belt conveyor 11.

[0036] Specifically, the mounting base 13 has an elongated hole 14, and the belt conveyor 11 has a threaded hole 15 that matches the elongated hole 14. The mounting base 13 is locked onto the belt conveyor 11 by the cooperation of the elongated hole 14 and the threaded hole 15, and by the bolts passing through the elongated hole 14 and screwed into the threaded hole 15, so that the position of the mounting base 13 can be adjusted left and right.

[0037] The chain conveyor 8 has a discharge plate 16 at its discharge end, which is oriented in the discharge direction and inclined downwards. The discharge plate 16 is mounted on the chain conveyor 8. When the yarn cone 20 or counterweight yarn is conveyed to the discharge end by the chain conveyor 8, the chain plate 10 is inclined downwards, and the yarn cone 20 or counterweight yarn on the chain plate 10 rolls onto the discharge plate 16. The yarn cone 20 or counterweight yarn then rolls onto the packaging conveying device 3 through the inclined discharge plate 16. Counterweight yarn that does not meet the requirements rolls onto the counterweight yarn conveying device 2 through the inclined discharge plate 16.

[0038] Furthermore, a roller 17 is rotatably mounted on the feeding end of the feed plate 16. A rotating shaft is installed on the feeding end of the feed plate 16, and the roller 17 is rotatably mounted on the rotating shaft. The roller 17 is designed to facilitate the rolling of the yarn package 20 or counterweight yarn from the chain plate 10 onto the feed plate 16.

[0039] The chain conveyor 8 has a feeding plate 18 at its feeding end, which is oriented towards the discharging direction and inclined downwards. The feeding plate 18 facilitates the rolling of the yarn cones 20 or counterweight yarns pushed out by the ejection mechanism onto the next conveying device.

[0040] Furthermore, the front and rear sides of the feeding plate 18 are provided with second limiting rails 19, which respectively limit the yarn package 20 or the counterweight yarn on both sides. The distance between the two second limiting rails 19 is adjustable, and can be achieved by adopting the installation structure of the first limiting rail 12. The setting of the second limiting rails 19 limits the yarn package 20 or the counterweight yarn pushed onto the feeding plate 18, which facilitates the conveying of the conveying device.

[0041] Two yarn package transfer conveying devices 4 are arranged at intervals along the front-to-back direction. Having two yarn package transfer conveying devices 4 can improve the transfer and conveying efficiency of the yarn packages 20 and increase their packaging efficiency.

[0042] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
