[0016] Furthermore, the photoelectric positioning and screening system is used to position the bobbin yarn to the lifting position and lift it up in sequence. When all the lifting positions are lifted up, all the lifting positions are controlled to fall down. Then, the suitable bobbin yarn is screened according to the weight of the bobbin yarn on each lifting position, and the lifting position where the suitable bobbin yarn is located is controlled to be lifted up.

DETAILED DESCRIPTION

[0028] Example 1: Figure 1 As shown, the whole package packaging and weighting system of bobbin yarn provided in this embodiment includes a weighing slide 21, a yarn taking device 22, a bobbin yarn aerial conveying and weighting device 23, a yarn unloading device 24, a stacking device 25, a destacking device 26, a conveyor line 27, a precise and efficient weighting device 28, and a packaging unit 29. The weighing slide 21, the yarn taking device 22, the bobbin yarn aerial conveying and weighting device 23, the yarn unloading device 24, and the stacking device 25 are connected in sequence, and the destacking device 26, the conveyor line 27, the precise and efficient weighting device 28, and the packaging unit 29 are connected in sequence.

[0029] The single bobbin yarn spun in the spinning area is transported to the weighing slide 21 for weighing, and then the bobbin yarn is placed on the bobbin yarn aerial conveying and balancing device 23 through the yarn taking device 22. The yarn unloading device 24 unloads the balanced bobbin yarn according to type and quantity, and then stacks it through the stacking device 25. The whole stack of bobbin yarn is moistened, and the whole stack of bobbin yarn after moisturization is separated by the destacking device 26 and placed on the conveyor line 27. The conveyor line 27 transports the bobbin yarn to the precise and efficient balancing device 28 for precise balancing. The balanced bobbin yarn is packaged through the packaging sleeve 29.

[0030] The weighing carriage 21 is used to weigh the bobbins; the yarn taking device 22 is used to place the weighed bobbins onto the bobbins aerial conveying and balancing device 23; the bobbins aerial conveying and balancing device 23 is used to perform initial bobbins balancing by type and transport the bobbins to the yarn unloading device 24 in the packaging area; the yarn unloading device 24 is used to unload the balanced bobbins according to type and quantity; the stacking device 25 is used to stack the bobbins into whole piles according to type; the destacking device 26 is used to separate the whole piles of bobbins that have been moistened and place them on the conveyor line 27; the precise and efficient balancing device 28 is used to perform precise balancing according to packaging requirements; and the packaging unit 29 is used to package the precisely balanced bobbins into packages. In this embodiment, the weighing carriage 21, the yarn taking device 22, the bobbins aerial conveying and balancing device 23, the yarn unloading device 24, the stacking device 25, the destacking device 26, the conveyor line 27, and the packaging unit 29 can all be implemented using existing technologies.

[0031] like Figure 2 As shown, the precise and efficient counterweight device 28 includes a bobbin belt conveyor unit 1, a bobbin translation conveyor unit 2, a bobbin lifting and screening counterweight unit 3, and a bobbin grabbing and translation unit 4.

[0032] The bobbin belt conveyor unit 1 uses a motor to drive a belt, thereby conveying the bobbins to the bobbin translation conveyor unit 2. The bobbin belt conveyor unit 1 is equipped with a single bobbin weighing module 5, which is used to weigh individual bobbins and store the weight of each bobbin in a precise and efficient weight counterweight device 28, thus creating a weight profile for each bobbin.

[0033] The bobbin translation conveying unit 2 includes two belt conveyor lines 6 arranged side by side on the left and right sides, and a lower translation sleeve 7 for translating the belt conveyor lines 6 on the left and right sides, so as to realize the normal conveying and storage of the bobbin yarn at the front end of the precise and efficient counterweight device 28 and the synchronous action of the bobbin yarn lifting and screening counterweight unit 3. When the bobbin belt conveyor unit 1 conveys the bobbin yarn to one of the belt conveyor lines 6, the other belt conveyor line 6 synchronously conveys the bobbin yarn on the belt conveyor line 6 to the bobbin yarn lifting and screening counterweight unit 3. At the same time, the reciprocating translation motion of the two belt conveyor lines 6 is realized by the lower translation sleeve 7 and the motor synchronous belt drive. The normal bobbin yarn conveying of the front-end process will not be affected by the bobbin yarn lifting and screening counterweight unit 3, and the counterweight belt conveyor line 8 can be fed synchronously. The combined action greatly improves the efficiency of the precise and efficient counterweight device 28.

[0034] like Figure 3As shown, the bobbin yarn lifting and screening counterweight unit 3 includes a main channel belt conveyor line 9, two counterweight belt conveyor lines 8 located on the left and right sides of the main channel belt conveyor line 9, a lifting unit 10, an air control system 11, and a photoelectric positioning and screening system. (1) The lifting unit 10 is used to lift the bobbin yarn on the lifting position 12 off the belt. In this embodiment, there are two sets of lifting units 10, and each set of lifting units 10 is adapted to a counterweight belt conveyor line 8. Each set of lifting units 10 includes multiple groups of lifting positions 12. The number of lifting positions 12 in each set of lifting units 10 can be 12 groups, 9 groups, 8 groups, 6 groups, etc. In this embodiment, each set of lifting units 10 includes 12 groups of lifting positions 12, and each group of lifting positions 12 has two lifting positions, and the two lifting positions 12 are located on the left and right sides of the corresponding counterweight belt conveyor line 8. As shown Figure 4 As shown, each group of lifting positions 12 is controlled to rise and fall by a cylinder 13 (MDBB32-250) and a guide shaft 14. (2) The counterweight belt conveyor line 8 is used to convey the weighed and stored bobbin yarn to the lifting position 12 of the lifting part sleeve 10. The belt width of the counterweight belt conveyor line 8 is 100 mm, and the bottom diameter of the bobbin yarn is 180 mm to 300 mm. When the front end bobbin yarn on the counterweight belt conveyor line 8 passes through the empty lifting position 12, the lifting position 12 is lifted up, thereby lifting the bobbin yarn off the belt. The lifting height of the lifting position 12 is based on not hindering the forward conveyance of the bobbin yarn on the counterweight belt conveyor line 8, that is, the lifting height of the lifting position 12 is higher than the height of the bobbin yarn. (3) The air control system 11 is used to provide pneumatic control. (4) The photoelectric positioning and screening system includes a photoelectric system, a cylinder magnetic switch, a weight sensor and a PLC controller. Its function is to position 12 bobbins to the lifting position 12 in sequence and lift them up in sequence. When all 12 groups of lifting positions 12 are lifted up, all 12 groups of lifting positions 12 are controlled to fall down. Then, the suitable bobbins are screened according to the weight of the bobbins on each lifting position 12, and the lifting position 12 where the suitable bobbins are located is controlled to be lifted up.

[0035] like Figure 3 As shown, the bobbin yarn grabbing and translating unit 4 is located above the bobbin yarn lifting and screening counterweight unit 3. The function of the bobbin yarn grabbing and translating unit 4 is to grab, translate and lift the bobbin yarn on the lifted lifting position 12 to the main channel belt conveyor line 9, and transport the bobbin yarn to the packaging sleeve 29 via the main channel belt conveyor line 9.

[0036] like Figure 3 and Figure 5 As shown, the bobbin grabbing and translation unit 4 includes a servo motor translation unit 15, a cylinder lifting unit 16, and a grabbing unit. The servo motor translation unit 15 drives the grabbing unit to translate left and right, while the cylinder lifting unit 16 raises and lowers the grabbing unit, which is used to grab and release bobbins. The grabbing unit includes 12 grippers 17 and a clamping cylinder 18 for controlling the opening and clamping of the grippers 17.

[0037] The method of using the precise and efficient counterweight device 28 is as follows: S1. The bobbin belt conveyor unit 1 conveys the bobbin through the belt. When the bobbin passes through the single bobbin weighing module 5, the single bobbin is weighed and recorded.

[0038] S2. A belt conveyor line 6 of the bobbin yarn translation conveying unit 2 is connected to the bobbin yarn belt conveying unit 1, and the bobbin yarn after weighing and recording is conveyed to the belt conveyor line 6 of the bobbin yarn translation conveying unit 2.

[0039] S3. When the belt conveyor line 6 is fully loaded with 12 bobbins, it docks with one of the counterweight belt conveyor lines 8 of the bobbin lifting and screening counterweight unit 3, and conveys the bobbins horizontally to the bobbin lifting and screening counterweight unit 3. Simultaneously, another belt conveyor line 6 docks with the bobbin belt conveyor unit 1, and steps S2 and S3 are repeated. The two belt conveyor lines 6 alternately store and convey bobbins, and the two counterweight belt conveyor lines 8 also operate alternately.

[0040] S4. After the bobbin yarn on the counterweight belt conveyor line 8 reaches the lifting position 12 of the lifting portion sleeve 10, the bobbin yarn on the lifting position 12 is lifted up until all the bobbin yarns on the 12 groups of lifting positions 12 of the unilateral lifting portion sleeve 10 are lifted up into position, and then the 12 groups of lifting positions 12 of the lifting portion sleeve 10 fall down together with the bobbin yarn.

[0041] S5. The grabbing sleeve of the package yarn grabbing translation unit 4 is translated to the top of the lifting sleeve 10, the grabbing sleeve falls, the clamping cylinder 18 clamps, and the position of the package yarn is adjusted. Then the clamping cylinder 18 is opened, and the grabbing sleeve rises to the grabbing position.

[0042] S6, the photoelectric positioning and screening system of the counterweight unit 3 for lifting and screening the bobbins of suitable weight will select the bobbins of suitable weight, and the lifting position 12 where the bobbins of suitable weight are located will lift the bobbins to the grabbing position. If there are only 4 bobbins of suitable weight among the 12 bobbins, the lifting positions 12 of these 4 bobbins will be lifted, while the lifting positions 12 of the remaining 8 bobbins will not move; when the belt conveyor line 6 is docked with the counterweight belt conveyor line 8 next time, only 4 bobbins will be transported from the belt conveyor line 6 to the counterweight belt conveyor line 8; at this time, there are still 8 bobbins on the belt conveyor line 6, and the belt drive motor will reverse, so that the 8 bobbins will follow the belt back to the front end of the belt conveyor line 6. It is worth noting that when the whole package of bobbins does not need to be counterweighted, the photoelectric positioning and screening system can be operated to assume that the bobbins on all the lifting positions 12 are bobbins of suitable weight, that is, all 12 bobbins will be lifted each time.

[0043] S7, the grabbing part grabs the bobbin yarn, and at this time the lifting position 12 falls, and the grabbing part moves the bobbin yarn horizontally to the upper side of the main channel belt conveyor line 9, and the clamping cylinder 18 opens, and the bobbin yarn is placed on the main channel belt conveyor line 9, and the main channel belt conveyor line 9 transports the bobbin yarn to the packaging part 29.

[0044] The precise and efficient counterweight device 28 provided by the present invention has two belt conveyor lines 6 that work alternately, so that the normal conveying of the front-end process of the yarn will not be affected by the yarn lifting and screening counterweight unit 3, and the counterweight belt conveyor line 8 can be fed synchronously, with compound actions, which greatly improves the working efficiency of the system. In addition, the yarn lifting and screening counterweight unit 3 and the yarn grabbing and translating unit 4 of the precise and efficient counterweight device 28 are equipped with 24-position lifting and screening, which can grab up to 12 yarns at a time, realizing efficient counterweight operation. In addition, the 24-position counterweight lifting and screening part sleeve realizes the free matching of yarn counterweights, which not only meets the 24-piece yarn counterweight mode of the carton, but also can be applied to the 12-piece / 8-piece yarn counterweight mode of the braided wire / heat shrink film. Compared with the existing counterweight mode, its structure is simpler and the action rhythm is faster, meeting the precise and efficient counterweight requirements of the yarn.

[0045] The present invention realizes the function of yarn conveying, moisture recovery and weighting packaging by connecting various devices in the whole package packaging and weighting process of yarn bobbins and performing two weighting operations before and after moisture recovery. The present invention not only improves work efficiency but also effectively reduces the labor intensity of skilled workers.

[0046] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
