Description

Technical Field

[0001] The invention relates to the technical field of bobbin production and packaging equipment, in particular to a double-loop type bobbin automatic weight balancing device. Background Art

[0002] In the current textile industry, when packaging bobbin yarn products, woven bags or cartons are generally used to pack a specified number of bobbins, with the total weight of each bag or box as the unit of measurement for delivery.

[0003] When using disposable woven bags for outer packaging, the standard net weight of each package is 25 kg or as required by the customer, the number of bobbins in each bag is 15 or as required by the customer, and the weight difference of each bag or box shall not exceed ±50 grams of the standard weight. The invention with publication number CN112061441B discloses a cheese weighting device and a weighting method thereof, which uses a light yarn feeding conveyor to convey light yarn with a weight less than the standard weight, and a light yarn weighing conveyor to weigh the light yarn, and a heavy yarn feeding conveyor to convey cheese yarn with a weight greater than the standard weight, and a heavy yarn weighing conveyor to weigh the heavy yarn. The controller algorithm module calculates the algorithm to find the optimal weighting scheme, drives the frame to move through the traverse mechanism and the lifting mechanism, so that the light yarn in the optimal weighting scheme moves to the weighting position, and the light yarn pushing mechanism pushes the light yarn to the weighting conveyor.

[0004] For the "pagoda-shaped" bobbin yarn with one end larger than the other, in order to improve the space utilization of the woven bag and the flatness of the stacking after packaging, and to prevent the bobbin yarn from being damaged by bumps during transportation, it is necessary to arrange the "big and small ends" of the bobbin yarn alternately when packaging the bobbin yarn in the woven bag. The bobbin yarn counterweight device of the above patent cannot flip and adjust the bobbin yarn, and it is also necessary to add a device similar to the bobbin yarn flipping device disclosed in the publication number CN214608329U before the bobbin yarn moves to the packaging machine, so that the "big and small ends" of the bobbin yarn are arranged alternately. Since the bobbin yarn counterweight time and flipping time are both included in the total packaging time, the packaging time is increased, resulting in a decrease in packaging efficiency, and also increasing the length of the bobbin yarn packaging line. In addition, the above-mentioned cheese yarn weighting device can only achieve weighting for the determined heavy yarn by selecting light yarn. Since it is impossible to select light yarn and heavy yarn for weighting at the same time, there is a high failure rate in weighting. If there is no light yarn suitable for the heavy yarn, the heavy yarn needs to be recovered, which increases the time consumption of weighting and reduces packaging efficiency. Summary of the invention

[0023] Beneficial effects of the present invention:

[0024] 1. This device adopts a double-loop bobbin storage weight-balancing structure, which can save floor space. The bobbin is weighed by a weighing conveyor. The bobbin with a weight less than the standard weight is a light yarn, and the bobbin with a weight greater than the standard weight is a heavy yarn. The bobbin pushing mechanism pushes the light yarn into the outer storage tank, and pushes the heavy yarn into the inner storage tank in a horizontal position; by selecting the best-balanced heavy yarn and light yarn from multiple heavy yarns and multiple light yarns, the average weight of the bobbin is closest to the standard bobbin weight, which improves the success rate of weight balancing and reduces the time-consuming bobbin recovery;

[0025] 2. The light yarn in the external storage tank is pushed out by the yarn pushing mechanism, and the heavy yarn in the horizontal posture is pushed to the inverted posture by the flip push plate. Then the inverted heavy yarn is pushed to the counterweight conveyor by the yarn pushing mechanism, which realizes the counterweight of the yarn and the flipping arrangement of the yarn, saving the packaging time of the yarn and improving the packaging efficiency of the yarn.

[0026] 3. The bobbins that cannot be loaded and weighed on the weighing conveyor will be automatically output to the bobbin recovery box and recovered by the bobbin recovery box, reducing the empty rate of the external storage trough and the internal storage trough, increasing the success rate of weight distribution and improving the weight distribution efficiency.

[0043] The bobbin yarn pushing mechanism includes a first power push rod 19 and a bobbin yarn pushing plate 20. The first power push rod 19 is installed on a side of the weighing conveyor 3 away from the outer ring storage distribution mechanism. The bobbin yarn pushing plate 20 is fixedly installed at the output end of the first power push rod 19. The first power push rod 19 drives the bobbin yarn pushing plate 20 to move along the conveying direction perpendicular to the weighing conveyor 3, so that the bobbin yarn pushing plate 20 pushes the bobbin yarn 2 on the weighing conveyor 3 with a weight less than the standard weight from the outer feed port 11 to the outer storage tank 8, and pushes the bobbin yarn 2 on the weighing conveyor 3 with a weight greater than the standard weight from the outer feed port 11 to the feeding channel 10 and the inner storage tank 15 in sequence; the first power push rod 19 can also drive the bobbin yarn pushing plate 20 to move to the outer feed port 11 to block the outer feed port 11 to prevent the bobbin yarn 2 in the outer storage tank 8 from being thrown out from the outer feed port 11 due to centrifugal force when the outer ring disk 6 rotates;

[0047] In order to facilitate the recovery of the bobbins 2 that cannot be loaded and reduce the empty rate of the outer storage tank 8 and the inner storage tank 15, the device is further provided with a bobbin recovery box 30, which is arranged at the unloading end of the weighing conveyor 3 and is used to receive the bobbins 2 outputted from the unloading end of the weighing conveyor 3.

The first proximity sensor 31 is used to detect whether the bobbin 2 moves to the pushing range of the bobbin pushing plate 20. When the first proximity sensor 31 detects a signal, the bobbin 2 enters the weighing conveyor 3. When the first proximity sensor 31 detects no signal, the bobbin 2 moves to the pushing range of the bobbin pushing plate 20, and the weighing conveyor 3 immediately stops conveying the bobbin 2.

[0049] In order to detect the bobbin yarn 2 entering the counterweight conveyor 26 , a second proximity sensor 32 is installed at the feeding end of the counterweight conveyor 26 .

[0050] In order to reduce the friction resistance of the bobbin 2 in contact with the stopper 27, a sliding sleeve 45 is rotatably mounted on the stopper 27. When the bobbin 2 contacts the sliding sleeve 45, the sliding sleeve 45 rotates on the stopper 27, thereby reducing the friction of the bobbin 2 and facilitating the bobbin 2 to tilt.

[0051] In order to facilitate the pushing of the three weighted bobbins 2 by the counterweight conveyor 26 to the packaging device, a mixed yarn pushing mechanism is provided at the unloading end of the counterweight conveyor 26, and the mixed yarn pushing mechanism includes a fifth power push rod 46, a mixed yarn push plate 47, a mixed yarn baffle 48 and a third proximity sensor 49. The output end of the fifth power push rod 46 is connected to the mixed yarn push plate 47, and the fifth power push rod 46 drives the mixed yarn push plate 47 to move linearly in a direction perpendicular to the conveying direction of the counterweight conveyor 26 to push the bobbins 2 on the counterweight conveyor 26 to the packaging device. The mixed yarn baffle 48 is fixed at the unloading end of the counterweight conveyor 26 to limit the passage of the bobbins 2. The counterweight conveyor 26 is installed with a third proximity sensor 49, and the third proximity sensor 49 is used to detect whether the counterweight conveyor 26 conveys the bobbins 2 to the pushing range of the mixed yarn push plate 47. The mixed yarn baffle 48 blocks the bobbin yarn 2, and the third proximity sensor 49 detects the number of bobbin yarns 2 passing through. When the number of bobbin yarns 2 reaches three, the fifth power push rod 46 drives the mixed yarn push plate 47 to push three weighted and arranged bobbin yarns 2 to the packaging device 50 at a time; the packaging device 50 is a packaging device of the prior art and is not the key point of the present invention.

[0052] The first proximity sensor 31, the second proximity sensor 32 and the third proximity sensor 49 are slot type photoelectric switches, and may also be diffuse photoelectric switches, through-beam photoelectric switches, mirror reflection type, fiber type photoelectric switches or capacitive proximity switches.

[0053] The first power push rod 19, the second power push rod 22, the third power push rod 24, the fourth power push rod 28 and the fifth power push rod 46 are cylinders, and may also be electric cylinders, hydraulic cylinders, gear rack mechanisms or ball screw structures.

[0054] In this embodiment, all electrical components and their corresponding power supplies are connected through wires, and a suitable controller should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle. The electrical connections between the electrical components are completed in a sequential working order. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principles and processes, and no longer explains the electrical control.

[0055] The working steps of the counterweight device of this embodiment are as follows:

[0056] S1: placing unweighed bobbins 2 on the bobbins conveyor 1, and the bobbins conveyor 1 conveys the bobbins 2 one by one to the weighing conveyor 3;

[0057] S2: The weighing conveyor 3 weighs the single bobbin 2 conveyed by the bobbin conveyor 1, and the storage module of the controller stores the weighing information of the bobbin 2; if the weight of the bobbin 2 on the weighing conveyor 3 is less than the standard weight, the bobbin 2 is a light yarn, and the bobbin pushing mechanism pushes the light yarn into the external storage tank 8. Specifically, Figure 3 As shown, the first power push rod 19 drives the bobbin yarn pushing plate 20 to move toward the outer feed port 11, and the bobbin yarn 2 enters the outer storage tank 8 from the outer feed port 11; then the first power push rod 19 drives the bobbin yarn pushing plate 20 to reset, and the first rotary power source 7 drives the outer ring disk 6 to rotate, so that the adjacent feeding channel 10 rotates to the outer feed port 11, and the weighing conveyor 3 weighs the next bobbin yarn 2 conveyed by the bobbin yarn conveyor 1; during this period, the second power push rod 22 drives the bobbin yarn pushing plate 25 to move to the outer feed port 12, blocking the outer feed port 12, so as to prevent the bobbin yarn 2 in the outer storage tank 8 from being thrown out from the outer feed port 12 due to centrifugal force;

[0058] If the weight of the bobbin 2 on the weighing conveyor 3 is greater than the standard weight, the bobbin 2 is a heavy yarn, and the bobbin pushing mechanism pushes the heavy yarn from the external feed port 11 to the feeding channel 10, the internal feed port 17, and the internal storage tank 15. Specifically, Figure 4 As shown, the second power push rod 22 drives the bobbin yarn pushing plate 25 to move to the inner discharge port 18, blocks the inner discharge port 18, and prevents the bobbin yarn 2 in the inner storage tank 15 from being thrown out of the inner discharge port 18 due to the centrifugal force. Then the first power push rod 19 drives the bobbin yarn pushing plate 20 to move toward the outer feed port 11, and the bobbin yarn 2 enters the feeding channel 10 from the outer feed port 11. The upper part of the bobbin yarn 2 contacts the sliding sleeve 45, and the bobbin yarn pushing plate 20 pushes the bobbin yarn 2 at the lower part of the bobbin yarn 2, so that the bobbin yarn 2 changes from an upright posture to an inclined posture under the interception of the slide table, and then the first power push rod 19 contracts to drive the bobbin yarn pushing plate 2 0 is away from the bobbin 2, and the bobbin 2 changes from an inclined posture to a horizontal posture due to gravity. The height of the bobbin 2 in the horizontal posture is lower than the sliding sleeve 45, and then the first power push rod 19 drives the bobbin pushing plate 20 again to push the bobbin 2, and pushes the bobbin 2 out of the feeding channel 10, and the bobbin 2 enters the inner storage tank 15 from the inner feeding port 17, and then the first power push rod 19 drives the bobbin pushing plate 20 to reset, and the second rotary power source 14 drives the outer ring disc 6 to rotate, so that the next adjacent unloaded inner storage tank 15 rotates to the inner feeding port 17, and the weighing conveyor 3 weighs the next bobbin 2 conveyed by the bobbin conveyor 1;

[0059] The bobbin ejection plate 25 moves to the outer discharge port 12 or the inner discharge port 18 accordingly according to the rotation of the outer ring disk 6 and the inner ring disk 13, and blocks the outer discharge port 12 or the inner discharge port 18;

[0060] S3: The storage module of the controller records the position information of each external storage tank 8 and the internal storage tank 15 and the weight information of the bobbin 2 stored therein; when the bobbin 2 weighed by the weighing conveyor 3 cannot be loaded any more, the loading of the bobbin 2 is completed and the weight balancing operation is started;

[0061] S4: The controller algorithm module runs the weight balancing algorithm, selects two outer storage slots 8 storing the best weight light yarns for discharging, and selects one inner storage slot 15 storing the best weight heavy yarns for discharging, so that the average weight of the two light yarns and one heavy yarn is closest to the weight of the standard bobbin yarn 2, as follows:

[0062] S41: First, one of the selected light yarns is pushed out, the first power push rod 19 drives the package yarn pushing plate 20 to move to the outer feed port 11, and the second power push rod 22 drives the package yarn pushing plate 25 to move to the outer feed port 12, so as to prevent the package yarn 2 in the outer storage tank 8 from being thrown out from the outer feed port 11 and the outer feed port 12 due to the centrifugal force when the outer ring disk 6 rotates;

[0063] S42: The first rotating power source 7 drives the outer ring disc 6 to rotate, so that one of the selected outer storage troughs 8 rotates to the outer feeding port 12, and then the third power push rod 24 drives the bobbin yarn pushing plate 25 to rise above the bobbin yarn 2, and the telescopic end of the second power push rod 22 contracts to drive the bobbin yarn pushing plate 25 to move to the inner feeding port 18, and then the telescopic end of the second power push rod 22 extends to drive the bobbin yarn pushing plate 25 to move to the outer feeding port 12, and the bobbin yarn pushing plate 25 pushes the bobbin yarn 2 in the outer storage trough 8 from the outer feeding port 12 to the counterweight conveyor 26;

[0064] S43: Then the selected heavy yarn is pushed out, and the second rotary power source 14 drives the inner ring disk 13 to rotate, so that the inner storage tank 15 storing the selected heavy yarn moves to the inner discharge port 18. When the inner ring disk 13 rotates, the outer sides of the inner discharge port 18 and the inner feed port 17 are limited by the vertical plates constituting the feeding channel 10, so as to prevent the bobbin yarn 2 in the inner storage tank 15 from being thrown out by the centrifugal force.

[0065] S44: the first rotating power source 7 drives the outer ring disk 6 to rotate so that the feeding channel 10 is aligned with the outer feeding port 12 and the outer feeding port 11;

[0066] S45: the telescopic end of the second power push rod 22 contracts to drive the package yarn pushing plate 25 to move into the feeding channel 10, blocking the feeding channel 10;

[0067] S46: Figure 5 As shown, the telescopic end of the fourth power push rod 28 extends out, driving the flip push plate 29 to pass through the opening, and the flip push plate 29 contacts the big end side of the bobbin yarn 2 in the inner storage tank 15 at the inner discharge port 18, and pushes the bobbin yarn 2 to rotate upward to an inverted posture with the small end facing downward, and the bobbin yarn pushing plate 25 blocks the inverted bobbin yarn 2 in the feeding channel 10 to prevent the bobbin yarn 2 from tipping toward the outer discharge port 12 due to inertia, so that the bobbin yarn 2 is in an inverted posture in the feeding channel 10;

[0068] S46: the third power push rod 24 drives the bobbin yarn pushing plate 25 to rise to a position higher than the bobbin yarn 2, the second power push rod 22 drives the bobbin yarn pushing plate 25 to move to the inner storage tank 15, the third power push rod 24 drives the bobbin yarn pushing plate 25 to descend to contact with the lower part of the bobbin yarn 2, the second power push rod 22 drives the bobbin yarn pushing plate 25 to move toward the outer feeding port 12, the bobbin yarn pushing plate 25 pushes the bobbin yarn 2 in the feeding channel 10 from the outer feeding port 12 to the counterweight conveyor 26, so as to realize the discharge of the heavy yarn;

[0069] S47: Finally, another selected light yarn is pushed out, which is the same as steps S41 and S42 and will not be described in detail;

[0070] S5: At this time, there are three arranged and weighted bobbins 2 on the weighted conveyor 26. The weighted conveyor 26 conveys the three bobbins 2 with heads in the form of "small, large, and small" in sequence to the mixed yarn pushing mechanism. The mixed yarn baffle 48 blocks the bobbins 2. After the third proximity sensor 49 detects that the number of bobbins 2 passing through reaches three, the third power push rod 24 drives the mixed yarn pushing plate 47 to push out three weighted and arranged bobbins 2 to the packaging device at one time.

[0071] S5: The controller algorithm module runs the weight balancing algorithm, and then selects a storage tank with the best weight of light yarn for discharging, and selects two inner storage tanks 15 with the best weight of heavy yarn for discharging, so that the average weight of the light yarn and the two heavy yarns is closest to the weight of the standard bobbin yarn 2, so that the three heads on the weight balancing conveyor 26 are sequentially conveyed to the mixed yarn pushing mechanism in the form of "large, small, and large" bobbin yarns 2, and the discharging is repeated until the bobbin yarn 2 pushed to the packaging device is as follows: Figure 1 Arranged in five columns as shown.

[0072] If the outer storage trough 8 or the inner storage trough 15 is mostly empty and there is no suitable light yarn or heavy yarn for counterweight, the loading operation is performed again; if at the end of loading, the empty rate of the outer storage trough 8 or the inner storage trough 15 is greater than 50%, that is, when the outer storage trough 8 is fully loaded with light yarn, the weighed bobbin yarn 2 on the weighing conveyor 3 is still light yarn, or when the inner storage trough 15 is fully loaded with heavy yarn, the weighed bobbin yarn 2 on the weighing conveyor 3 is still heavy yarn, the weighing conveyor 3 outputs the weighed bobbin yarn 2 to its unloading end, falls into the bobbin yarn recovery box 30, and then the next bobbin yarn 2 is weighed until the empty rate requirement of greater than 50% is met. The empty rate can be flexibly set and adjusted according to actual conditions.
