Description

Technical Field

[0001] The utility model relates to the technical field of conveying and detecting, in particular to a yarn bobbin conveying and detecting device for a dynamic scale conveyor belt. Background Technique

[0002] The statements herein only provide background techniques related to the utility model and do not necessarily constitute prior art.

[0003] In the textile production process, weighing the yarn bobbins is an important quality control step. By weighing, it can be ensured that the weight of each yarn bobbin meets the specified standards, and the weight consistency directly affects the quality of subsequent textile processes.

[0004] Currently, a dynamic scale is generally used to weigh the yarn bobbins. However, due to production reasons, the conveying frequency of the yarn bobbins fluctuates. When the conveying frequency of the yarn bobbins decreases, the dynamic scale is still in operation. At this time, not only is electric energy wasted, but also the wear of the rollers and bearings is aggravated. Therefore, a yarn bobbin conveying and detecting device for a dynamic scale conveyor belt is proposed to control the start and stop of the dynamic scale and reduce power consumption and wear. Content of the Utility Model

[0005] The purpose of the utility model is to address the above deficiencies and provide a yarn bobbin conveying and detecting device for a dynamic scale conveyor belt, which can detect the conveying frequency of the yarn bobbins, enable the dynamic scale to start and stop in a timely manner, and reduce power consumption and wear.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions: A yarn bobbin conveying and detecting device for a dynamic scale conveyor belt, comprising:

[0007] A relay conveyor, which is located between the feeding conveyor and the dynamic scale, is used to receive the yarn bobbins output by the feeding conveyor and convey the yarn bobbins towards the dynamic scale side. Two side plates for preventing the yarn bobbins from falling are symmetrically arranged on the relay conveyor;

[0008] An optoelectronic detection mechanism, which is arranged on the side plate and is used to detect whether the feeding conveyor conveys the yarn bobbins to the relay conveyor and transmit the detection signal to the dynamic scale controller;

[0009] An intermittent conveying mechanism, which is arranged between the two side plates and is used to intercept the yarn bobbins and intermittently push the intercepted yarn bobbins onto the dynamic scale.

[0010] Further, the relay conveyor is a non-powered roller conveyor, and the ground clearance of the relay conveyor on the side close to the feeding conveyor is higher than the ground clearance of the relay conveyor on the side close to the dynamic scale.

[0011] Further, a guiding mechanism for guiding the yarn bobbins to be arranged one by one during the conveying process is arranged between the two side plates;

[0012] The guiding mechanism includes a fixed guiding member and a movable guiding member located between two side plates. Both the fixed guiding member and the movable guiding member include guide rails, and each guide rail is composed of a parallel section and a guiding section provided at one end of the parallel section away from the dynamic scale. The distance between the two ends of the two guiding sections away from the dynamic scale is greater than the distance between the two ends of the two guiding sections close to the dynamic scale. The guide rail of the fixed guiding member is fixedly connected to the adjacent side plate. On the side of the guide rail of the movable guiding member close to the adjacent side plate, there are a plurality of guide posts penetrating the adjacent side plate and an adjusting screw threadedly connected to the adjacent side plate. The adjusting screw is rotatably connected to the side plate and is used to push the guide rail of the movable guiding member to move towards and away from the fixed guiding member.

[0013] Furthermore, the photoelectric detection mechanism is composed of a transmitter and a receiver. A strip-shaped hole is opened at the top of the parallel section of the guide rail.

A first intercepting plate that rotates with the turning shaft is arranged on the turning shaft at the bottom of the fixed guiding member. The first intercepting plate is located at the end of the turning shaft close to the dynamic scale. A second intercepting plate that rotates with the turning shaft is arranged on the turning shaft at the bottom of the movable guiding member. The second intercepting plate is located at the end of the turning shaft away from the dynamic scale and can move axially along the turning shaft. The distance between the second intercepting plate and the first intercepting plate is equal to the diameter of the cheese. A top block is arranged on the side of the second intercepting plate close to the dynamic scale for pushing the cheese to move towards the dynamic scale when the second intercepting plate rotates;

[0015] The intermittent conveying mechanism further includes a cross beam arranged on the two side plates. A driving component for driving the two turning shafts to rotate in the same direction is arranged on the cross beam. The driving component includes a double-headed motor. An expansion rod is arranged at the output end of the double-headed motor. A driving gear that moves towards and away from the double-headed motor along with the transmission component is arranged at the end of the expansion rod away from the double-headed motor. A driven gear meshing with the driving gear is arranged at the input end of the transmission component. When the first intercepting plate is within the moving area of the cheese, the second intercepting plate is not within the moving area of the cheese. When the second intercepting plate is within the moving area of the cheese, the first intercepting plate is not within the moving area of the cheese.

[0016] Further, an adjusting rod is rotatably arranged on the side of the second intercepting plate away from the dynamic scale, and the adjusting rod can move axially along the rotation axis following the second intercepting plate. One end of the adjusting rod away from the rotation axis is inserted into the cross beam, and a guide groove is formed in the cross beam to guide the adjusting rod to move axially along the rotation axis synchronously when the adjusting rod moves on the guide rail of the movable guiding member.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 , the present invention discloses a bobbin yarn conveying and detecting device for a dynamic scale conveyor belt, including:

[0030] A relay conveyor 1, which is located between the loading conveyor 2 and the dynamic scale 3, is used to receive the bobbin yarn output by the loading conveyor 2 and convey the bobbin yarn to the side close to the dynamic scale 3. Two side plates 4 for preventing the bobbin yarn from falling are symmetrically arranged on the relay conveyor 1;

[0031] A photoelectric detection mechanism 5, which is arranged on the side plate 4, is used to detect whether the loading conveyor 2 conveys the bobbin yarn to the relay conveyor 1 and transmit the detection signal to the controller of the dynamic scale 3;

[0032] An intermittent conveying mechanism 6, which is arranged between the two side plates 4, is used to intercept the bobbin yarn and intermittently push the intercepted bobbin yarn onto the dynamic scale 3.

[0033] In the present invention, by arranging a bobbin yarn conveying and detecting device composed of a relay conveyor 1, a photoelectric detection mechanism 5 and an intermittent conveying mechanism 6 between the loading conveyor 2 and the dynamic scale 3, the relay conveyor 1 is used to transfer the bobbin yarn, and the photoelectric detection mechanism 5 is used to detect the conveying frequency of the bobbin yarn during the transfer process, so that the dynamic scale 3 can stop working in time when the bobbin yarn is conveyed slowly, saving electric energy and reducing wear. By arranging the intermittent conveying mechanism 6, the bobbin yarn on the relay conveyor 1 is conveyed to the dynamic scale 3 one by one for detection, avoiding the situation that multiple bobbin yarns are conveyed at the same time and causing inaccurate detection results.

[0034] In one embodiment, the relay conveyor 1 is a non-powered roller conveyor, and the height of the relay conveyor 1 from the ground on the side close to the feeding conveyor 2 is higher than the height of the relay conveyor 1 from the ground on the side close to the dynamic scale 3.

[0035] With such a design, the cheese yarn output from the feeding conveyor 2 can slide under the action of gravity to the side of the relay conveyor 1 close to the dynamic scale 3 until it stops moving under the interception of the intermittent conveying mechanism 6. This not only enables the normal conveying and arrangement of the cheese yarn, but also does not affect the normal movement of the remaining cheese yarn after the cheese yarn is blocked and stops.

[0036] In one embodiment, a guiding mechanism 7 for guiding the cheese yarn to be arranged one by one during the conveying process is provided between the two side plates 4;

[0037] The guiding mechanism 7 includes a fixed guiding member 71 and a movable guiding member 72 located between the two side plates 4. Both the fixed guiding member 71 and the movable guiding member 72 include guide rails 711. The guide rails 711 are composed of parallel segments and guiding segments provided at one end of the parallel segments away from the dynamic scale 3. The distance between the ends of the two guiding segments away from the dynamic scale 3 is greater than the distance between the ends of the two guiding segments close to the dynamic scale 3. The guide rail 711 of the fixed guiding member 71 is fixedly connected to the adjacent side plate 4. A plurality of guide posts 721 penetrating the adjacent side plate 4 and an adjusting screw 722 threadedly connected to the adjacent side plate 4 are provided on the side of the guide rail 711 of the movable guiding member 72 close to the adjacent side plate 4. The adjusting screw 722 is rotatably connected to the side plate 4 and is used to push the guide rail 711 of the movable guiding member 72 to move towards and away from the fixed guiding member 71.

[0038] With such a design, the operator can push the guide rail 711 of the movable guiding member 72 closer to or farther away from the fixed guiding member 71 by rotating the adjusting screw 722, so as to be able to adjust the distance between the two guide rails 711 according to the model of the produced cheese yarn, ensuring that the cheese yarn can be conveyed and arranged one by one, and improving the detection accuracy of the subsequent dynamic scale 3.

[0039] In specific implementation, scale grooves can be opened on the guide posts 721 to assist the operator in judging the moving distance of the guide rail 711 on the movable guiding member 72.

[0040] In one embodiment, the photoelectric detection mechanism 5 is composed of a transmitter and a receiver. A strip-shaped hole is opened at the top of the parallel segment of the guide rail 711. The working ends of the transmitter and the receiver are respectively inserted into the strip-shaped holes of the two guide rails 711, and a light-penetrating hole for light to penetrate is opened on the opposite side of the two guide rails 711.

[0041] With such a design, because a light-penetrating hole for light to penetrate is opened on the guide rail 711, the movement or non-movement of the guide rail 711 will not affect the normal use of the photoelectric detection mechanism 5.

[0042] In specific implementation, since the cheese moves between the transmitter and the receiver when moving on the relay conveyor 1, blocking the beam transmission, the conveying frequency of the cheese can be determined by counting the time interval between two adjacent beam interruptions; when the photoelectric detection mechanism 5 is not triggered for a long time, the controller of the dynamic scale 3 controls the dynamic scale 3 to stop operating until the photoelectric detection mechanism 5 detects the passing of the cheese again and then resumes starting; when the photoelectric detection mechanism 5 detects that the conveying frequency of the cheese is higher than the detection frequency of the dynamic scale 3, the controller of the dynamic scale 3 controls the dynamic scale 3 to operate normally; when the photoelectric detection mechanism 5 detects that the conveying frequency of the cheese is lower than the detection frequency of the dynamic scale 3, the operation of the dynamic scale 3 is stopped first until the cheese intercepted by the intermittent conveying mechanism 6 accumulates to completely block the photoelectric detection mechanism 5. At this time, the dynamic scale 3 is started again, and after the dynamic scale 3 operates for a certain set time, it is stopped again and the above operations are repeated.

[0043] In an embodiment, the intermittent conveying mechanism 6 includes a transmission assembly 61 respectively arranged on two guide rails 711. A turning shaft 62 is arranged at the bottom of the guide rail 711 between the output end of the transmission assembly 61 and the end of the guide rail 711 close to the dynamic scale 3. A first intercepting plate 63 that rotates with the turning shaft 62 is arranged on the turning shaft 62 at the bottom of the fixed guide member 711. The first intercepting plate 63 is located at the end of the turning shaft 62 close to the dynamic scale 3. A second intercepting plate 64 that rotates with the turning shaft 62 is arranged on the turning shaft 62 at the bottom of the movable guide member 72. The second intercepting plate 64 is located at the end of the turning shaft 62 away from the dynamic scale 3 and the second intercepting plate 64 can move along the axial direction of the turning shaft 62. The distance between the second intercepting plate 64 and the first intercepting plate 63 is equal to the diameter of the cheese. A top block 65 is arranged on the side of the second intercepting plate 64 close to the dynamic scale 3 for pushing the cheese to move towards the side close to the dynamic scale 3 when the second intercepting plate 64 rotates.

[0044] The intermittent conveying mechanism 6 further includes a cross beam 66 arranged on two side plates 4. A driving assembly 67 for driving the two turning shafts 62 to rotate in the same direction is arranged on the cross beam 66. The driving assembly 67 includes a double-headed motor. An expansion rod is arranged at the output end of the double-headed motor. A driving gear that moves towards and away from the double-headed motor side following the transmission assembly 61 is arranged at the end of the expansion rod away from the double-headed motor. A driven gear meshing with the driving gear is arranged at the input end of the transmission assembly 61. When the first intercepting plate 63 is in the cheese moving area, the second intercepting plate 64 is not in the cheese moving area. When the second intercepting plate 64 is in the cheese moving area, the first intercepting plate 63 is not in the cheese moving area.

[0045] With such a design, after the driving force of the driving component 67 is adjusted by the guide rail 711, it can still be transmitted to the turning shaft 62 through the transmission component 61, so that the two turning shafts 62 can drive the first intercepting plate 63 and the second intercepting plate 64 to rotate synchronously. When the cylindrical yarn being conveyed is intercepted by the first intercepting plate 63, since the second intercepting plate 64 is not in the moving area of the cylindrical yarn, the subsequent cylindrical yarn can continue to approach the intercepted cylindrical yarn. When the first intercepting plate 63 rotates to no longer intercept the cylindrical yarn, at this time, the second intercepting plate 64 intercepts the cylindrical yarn adjacent to the cylindrical yarn close to the dynamic scale 3, and during the subsequent rotation process, the top block 65 is used to push a part of the cylindrical yarn close to the dynamic scale 3 to move onto the dynamic scale 3, so that the dynamic scale 3 can drive the cylindrical yarn to completely move onto the dynamic scale 3 for detection. By continuously rotating the turning shaft 62 and repeating the above operations, the effect of intermittently conveying the cylindrical yarn can be achieved.

[0046] During specific implementation, the conveying interval of the intermittent conveying mechanism 6 is not less than the detection time of the cylindrical yarn by the dynamic scale 3, ensuring that only a single cylindrical yarn is detected each time. At the same time, the contact point of the top block 65 with the cylindrical yarn is as close to the lower part as possible to ensure the stability of pushing the cylindrical yarn and avoid the cylindrical yarn from tipping over.

[0047] It should be noted that the transmission component 61 belongs to a mature existing technology and will not be elaborated too much here.

[0048] In an embodiment, an adjusting rod 8 that can move axially along the turning shaft 62 following the second intercepting plate 64 is rotatably arranged on the side of the second intercepting plate 64 away from the dynamic scale 3. One end of the adjusting rod 8 away from the turning shaft 62 is inserted into the cross beam 66, and a guide groove for guiding the adjusting rod 8 to move axially along the turning shaft 62 synchronously when moving on the guide rail 711 of the moving guide member 72 is provided in the cross beam 66.

[0049] With such a design, when the guide rail 711 of the moving guide member 72 moves, the second intercepting plate 64 can be synchronously adjusted under the guidance of the guide groove and the adjusting rod 8, so that the distance between the second intercepting plate 64 and the first intercepting plate 63 conforms to the adjusted cylindrical yarn model, which not only saves the time for separately adjusting the second intercepting plate 64, but also improves the adjustment accuracy.

[0050] In an embodiment, a cleaning mechanism 9 for cleaning the working ends of the transmitter and the receiver is provided on the guide rail 711; the cleaning mechanism 9 includes a bidirectional screw 91 arranged between the transmission component 61 and the end of the guide rail 711 away from the dynamic scale 3. The bidirectional screw 91 is connected to the output end of the transmission component 61, and a cleaning brush 92 that is inserted into the strip-shaped hole and can be driven by the bidirectional screw 91 to move axially along the bidirectional screw 91 to clean the working ends of the transmitter and the receiver is provided on the bidirectional screw 91.

[0051] With such a design, the driving power of the driving component 67 is utilized to drive the rotation of the bidirectional screw 91, enabling the cleaning brush 92 to achieve the effect of regularly cleaning the working ends of the transmitter and the receiver during reciprocating movement, and reducing the influence of production dust on the detection accuracy.

[0052] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0053] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0054] In addition, "a plurality of" means two or more.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
