Description

Technical Field

[0001] The present application relates to the field of textile machines, and particularly to a single-end doffing device, a control method and a control device for single-end doffing. Background Art

[0002] In a semi-automatic rotor spinning machine, it generally includes a plurality of yarn machine workstations. The yarn machine workstation may include a spinning mechanism and a winding mechanism; the spinning mechanism is used to produce yarn, and the winding mechanism winds the yarn; a yarn taking-out device may also be arranged between the spinning mechanism and the winding mechanism to guide the yarn by using a yarn taking-out roller and a pressure roller, etc., so that the winding mechanism can efficiently wind the yarn. The winding mechanism generally uses a tube to cross-wind the yarn to form a yarn bobbin or a yarn package of a certain size.

[0003] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely explaining the technical solutions of the present application and facilitating the understanding of those skilled in the art, and it cannot be considered that the above technical solutions are well-known to those skilled in the art just because these solutions are described in the background art part of the present application. Summary of the Invention

[0004] However, the inventors found that: at present, the semi-automatic rotor spinning machine still requires manual intervention, such as manually replacing the tube after the yarn bobbin is completed; therefore, the maintenance cost is still relatively high, the safety is relatively low and the working efficiency is not high.

[0005] In order to solve at least one of the above problems or other similar problems, embodiments of the present application provide a single-end doffing device, a control method and a control device for single-end doffing, expecting to reduce or avoid manual intervention, reduce the maintenance cost, and improve the safety and working efficiency.

[0006] According to one aspect of the embodiments of the present application, a single-end doffing device is provided, including:

[0007] A yarn machine workstation having a spinning mechanism for producing yarn and a winding mechanism for winding the yarn; wherein a replaceable tube is arranged on the winding mechanism, and the tube is used for winding the yarn;

[0008] A control device that sends control information for instructing to replace the yarn bobbin on the winding mechanism when the tube on the winding mechanism is wound into a yarn bobbin of a predetermined size; and

[0009] A tube replacement device stores one or more tubes and uses the stored tubes to replace the yarn bobbin on the winding mechanism upon receiving the control information.

[0010] Thus, by replacing the yarn bobbin on the winding mechanism with the tubes stored in the tube replacement device, the yarn bobbin can be automatically replaced with an empty tube after the yarn winding is completed, reducing or avoiding manual intervention, lowering maintenance costs, and enhancing safety and work efficiency.

[0011] In some embodiments, the control device sends the control information to the tube replacement device when the yarn length of the yarn bobbin reaches a predetermined length, or the weight of the yarn bobbin reaches a predetermined weight, or the diameter of the yarn bobbin reaches a predetermined diameter, or the length of the yarn bobbin reaches a predetermined length.

[0012] Thus, the control device can further accurately control the replacement timing, improving work efficiency.

[0013] In some embodiments, the control device sends a control instruction to stop winding to the yarn machine workstation when the yarn length of the yarn bobbin reaches a predetermined length, or the weight of the yarn bobbin reaches a predetermined weight, or the diameter of the yarn bobbin reaches a predetermined diameter, or the length of the yarn bobbin reaches a predetermined length, and causes the yarn bobbin to pop out from the winding mechanism onto the conveyor belt.

[0014] Thus, the control device can further accurately control the replacement timing, improving work efficiency.

[0015] In some embodiments, after the yarn bobbin on the winding mechanism is popped out, the tube replacement device pushes out the stored tube at the loading position and configures the tube onto the winding mechanism.

[0016] Thus, under the instruction of the control device, the tube replacement device and the winding mechanism can cooperate in parallel, further accurately controlling the replacement timing and improving work efficiency.

[0017] In some embodiments, the tube replacement device moves from the loading position to the loading position upon receiving a control instruction; or, the tube replacement device moves from the loading position to the loading position during the spinning process; or, the tube replacement device moves from the loading position to the loading position after storing the tube and remains at the loading position when there is a tube in the replacement device.

[0018] Thus, the tube replacement device can reach the loading position (standby position) in advance before the spinning process is interrupted, thereby saving the time for replacing the tube, further accurately controlling the replacement timing, and improving work efficiency.

[0019] In some embodiments, the control device detects whether the tube is configured on the winding mechanism, and when the tube is correctly configured on the winding mechanism, sends a control instruction to start the production and winding of yarn to the yarn machine workstation.

[0020] Thus, through the detection of the control device, the timing for the winding mechanism to work again can be accurately determined, further improving safety and work efficiency.

[0021] In some embodiments, when the tube is correctly configured on the winding mechanism, the control device also sends a control instruction to the tube replacement device to move the tube replacement device back from the introduction position to the loading position or the standby position.

[0022] Thus, through the detection of the control device, the timing for the tube replacement device to standby and introduce can be accurately determined, further improving safety and work efficiency. In addition, after the tube replacement device moves back to the loading position or the standby position, maintenance and tube loading can be better performed.

[0023] According to another aspect of the embodiments of the present application, a control method for single-end doffing is provided, including:

[0024] When the tube on the winding mechanism in the yarn machine workstation is wound into a yarn bobbin of a predetermined size, the control device sends control information for instructing the replacement of the yarn bobbin on the winding mechanism; and

[0025] When the tube replacement device receives the control information, it uses the stored tube to replace the yarn bobbin on the winding mechanism.

[0026] Thus, by replacing the yarn bobbin on the winding mechanism with the tube stored in the tube replacement device, the yarn bobbin can be automatically replaced with an empty tube after the yarn winding is completed, reducing or avoiding manual intervention, lowering the maintenance cost, and improving safety and work efficiency.

[0027] In some embodiments, the control device sends the control information to the tube replacement device when the yarn length of the yarn bobbin reaches a predetermined length, or the weight of the yarn bobbin reaches a predetermined weight, or the diameter of the yarn bobbin reaches a predetermined diameter, or the length of the yarn bobbin reaches a predetermined length.

[0028] Thus, the control device can further accurately control the replacement timing, improving work efficiency.

[0029] In some embodiments, the method further includes:

[0030] When the length of the yarn on the yarn bobbin reaches a predetermined length, or the weight of the yarn bobbin reaches a predetermined weight, or the diameter of the yarn bobbin reaches a predetermined diameter, or the length of the yarn bobbin reaches a predetermined length, the control device sends a control instruction to stop winding to the yarn machine workstation, and ejects the yarn bobbin from the winding mechanism onto the conveyor belt.

[0031] Thus, the control device can further accurately control the timing of replacement, improving work efficiency.

[0032] In some embodiments, the method further includes:

[0033] After the yarn bobbin on the winding mechanism is ejected, the tube replacement device ejects the stored tube at the loading position and configures the tube onto the winding mechanism.

[0034] Thus, under the instruction of the control device, the tube replacement device and the winding mechanism can cooperate in parallel, further accurately controlling the timing of replacement and improving work efficiency.

[0035] In some embodiments, the method further includes:

[0036] The tube replacement device moves from the loading position to the loading position when receiving a control instruction; or, the tube replacement device moves from the loading position to the loading position during the spinning process; or, the tube replacement device moves from the loading position to the loading position after storing the tube, and remains at the loading position when there is a tube in the replacement device.

[0037] Thus, the tube replacement device can reach the loading position (standby position) in advance before the interruption of the spinning process, saving the time for replacing the tube, further accurately controlling the timing of replacement, and improving work efficiency.

[0038] In some embodiments, the method further includes:

[0039] The control device detects whether the tube is configured on the winding mechanism. When the tube is correctly configured on the winding mechanism, the control device sends a control instruction to start production and wind yarn to the yarn machine workstation.

[0040] Thus, through the detection of the control device, the timing for the winding mechanism to work again can be accurately determined, further improving safety and work efficiency.

[0041] In some embodiments, the method further includes:

[0042] When the tube is correctly configured on the winding mechanism, the control device further sends a control instruction to the tube replacement device to cause the tube replacement device to move back from the introduction position to the loading position or the standby position.

[0043] Thus, through the detection of the control device, the timing of the standby and introduction of the tube replacement device can be accurately determined, further improving safety and work efficiency. In addition, after the tube replacement device moves back to the loading position or the standby position, maintenance and tube loading can be better performed.

[0044] According to another aspect of the embodiments of the present application, a control device for single-end doffing is provided, including a memory and a processor. The memory stores a computer program, and the processor is configured to execute the computer program to implement the following operations:

[0045] When the tube on the winding mechanism in the yarn machine workstation is wound into a yarn bobbin of a predetermined size, send control information for instructing the replacement of the yarn bobbin on the winding mechanism, so that the tube replacement device uses the stored tube to replace the yarn bobbin on the winding mechanism.

[0046] One of the beneficial effects of the embodiments of the present application is that by replacing the yarn bobbin on the winding mechanism with the tube stored in the tube replacement device, the yarn bobbin can be automatically replaced with an empty tube after the yarn winding is completed, reducing or avoiding manual intervention, lowering the maintenance cost, and improving safety and work efficiency.

[0061] The following describes the embodiments of the present application with reference to the accompanying drawings.

[0062] The embodiments of the present application provide a single-end doffing device, including a yarn machine workstation, a control device, and a tube replacement device.

[0063] Figure 1 is a schematic diagram of a yarn machine workstation according to an embodiment of the present application. As Figure 1 shown, the yarn machine workstation 100 includes a spinning mechanism 101 and a winding mechanism 102; the spinning mechanism 101 is used to produce yarn 11, and the winding mechanism 102 is used to wind the yarn 11; as Figure 1 shown, a yarn extraction device 103 may also be provided between the spinning mechanism 101 and the winding mechanism 102.

[0064] As Figure 1 shown, the winding mechanism 102 may be configured with a tube 1021, and the tube 1021 may cross-wind the yarn 11 to form a yarn bobbin 1022; the winding mechanism 102 may be independently driven by a driver, and may also have mechanisms such as a conveyor belt for transporting the yarn bobbin 1022. For specific details of the winding mechanism 102, reference may also be made to related technologies.

[0065] As Figure 1 shown, the yarn machine workstation 100 may be controlled by a computer workstation 12, and the computer workstation 12 controls the actions of each component of one or more yarn machine workstations 100. The control device according to the embodiment of the present application may be implemented, for example, by Figure 1 the computer workstation 12, but the present application is not limited thereto. For example, the control device may also be a certain control circuit or the like configured in the yarn machine workstation 100 or other devices.

[0066] It should be noted that Figure 1 only a schematic description of the yarn machine workstation of the present application is given, but the present application is not limited thereto; for example, other components or devices may also be provided. Specifically, reference may be made to related technologies, and the description is omitted here. Figure 1 For components or elements not specifically specified in

[0067] Figure 2 (such as control lines, connection components, etc.), reference may be made to related technologies, and the present application does not limit this. Figure 3 is a schematic diagram of a single-end doffing device according to an embodiment of the present application, in which the control device is omitted. Figure 2 is a partial method diagram of the single-end doffing device Figure 4 showing the situation of the winding mechanism of a yarn machine workstation and a tube replacement device. Figure 2 is another schematic diagram of the single-end doffing device

[0068] As Figures 2 to 4 shown, the single-end doffing device 200 may include a yarn workstation 201 and a tube replacement device 202. The structure of the yarn workstation 201 may also refer to Figure 1 . Figures 2 to 4For simplicity, only one yarn workstation is taken as an example to show the reference numeral 201 in the drawings.

[0069] The yarn machine workstation 201 has a spinning mechanism for producing yarn ( Figure 2 not shown in the drawings) and a winding mechanism 2011 for winding the yarn; a replaceable tube (as Figure 1 shown by 1021 in the drawings, Figure 2 not shown in the drawings) is arranged on the winding mechanism 2011, and the tube is used for winding the yarn.

[0070] A control device ( Figure 2 not shown in the drawings) sends control information for instructing to replace the yarn bobbin on the winding mechanism 2011 when the tube on the winding mechanism 2011 is wound into a yarn bobbin of a predetermined size (as Figure 1 shown by 1022 in the drawings, Figure 2 not shown in the drawings).

[0071] The tube replacement device 202 stores one or more tubes; when receiving the control information, the tube replacement device 202 can use the stored tubes to replace the yarn bobbin on the winding mechanism 2011.

[0072] In some embodiments, as Figure 2 shown, for example, a plurality of yarn machine workstations 201 can be configured (for example, Figure 2 12 are shown to be configured on the front side), and a tube replacement device 202 can be respectively configured for each yarn machine workstation 201 ( Figure 2 only 1 is shown to be configured on the front side for illustration). One or more tubes can be stored in the tube replacement device 202 (for example, 6 tubes can be stored side by side). The above are only some examples of the present application, but are not limited thereto.

[0073] Thus, by replacing the yarn bobbin on the winding mechanism with the tubes stored in the tube replacement device, the yarn bobbin can be automatically replaced with an empty tube after the yarn winding is completed, reducing or avoiding manual intervention, lowering the maintenance cost, and improving the safety and work efficiency.

[0074] It should be noted that Figures 2 to 4 only the single-end doffing device of the present application is schematically described, but the present application is not limited thereto; for example, other components or devices can also be provided, and reference can be made to the related art specifically, and the description is omitted here. Figures 2 to 4 For components or elements not specifically specified in the drawings (such as control circuits, etc.), reference can be made to the related art, and the present application does not limit this.

[0075] In some embodiments, when the yarn length of the yarn bobbin (the total length of the yarn wound on the yarn bobbin) reaches a predetermined length (the first length), or the weight of the yarn bobbin reaches a predetermined weight, or the diameter of the yarn bobbin reaches a predetermined diameter, or the length of the yarn bobbin (the length of the yarn bobbin itself) reaches a predetermined length (the second length), the control device sends the control information to the tube replacement device 202.

[0076] For example, assume Figure 1 that the diameter of the yarn bobbin 1022 shown in reaches the previously required diameter threshold, then the yarn bobbin 1022 needs to be replaced. The yarn length can be detected by a sensor of the spinning mechanism, and the diameter / length / weight of the yarn bobbin can be detected by sensors of the winding mechanism, etc. Specific detection components can refer to related technologies. This application is not limited thereto. For example, the parameter as the doffing condition can also be the volume of the yarn bobbin, etc. In addition, the above doffing conditions can be used alone, or two or more doffing conditions can be combined.

[0077] Thus, the control device can further accurately control the replacement timing and improve work efficiency.

[0078] In some embodiments, when the yarn length of the yarn bobbin reaches a predetermined length, or the weight of the yarn bobbin reaches a predetermined weight, or the diameter of the yarn bobbin reaches a predetermined diameter, or the length of the yarn bobbin reaches a predetermined length, the control device sends a control command to stop winding to the yarn machine workstation 201, and causes the yarn bobbin to pop out from the winding mechanism 2011 onto the conveyor belt.

[0079] For example, after receiving the control command, the yarn machine workstation 201 can consider that the winding of the yarn bobbin has been completed. Therefore, it can stop the yarn production and winding of the yarn machine workstation 201 and prepare to start the replacement of the yarn bobbin. For other yarn machine workstations 201, the yarn production and winding can still be carried out independently and are not affected by this control command.

[0080] Thus, the control device can further accurately control the replacement timing and improve work efficiency.

[0081] In some embodiments, after the yarn bobbin on the winding mechanism is popped out, the tube replacement device 202 pushes out the stored tube at the import position and configures the tube onto the winding mechanism.

[0082] Thus, under the instruction of the control device, the tube replacement device and the winding mechanism can cooperate in parallel (for example, while popping out the yarn bobbin, while importing the stored empty tube, etc.), which can further accurately control the replacement timing and improve work efficiency.

[0083] In some embodiments, the insertion position refers to, for example, the position where the empty tube in the tube replacement device can be inserted into the bobbin holder of the winding mechanism, and the standby position refers to, for example, the position where the tube replacement device waits for the tube replacement operation. The insertion position and the standby position can be near the winding mechanism and have a predetermined distance from the winding mechanism.

[0084] The insertion position can be the same as the standby position. For example, the tube replacement device can standby at a first predetermined position near the winding mechanism and replace the tube at this first predetermined position; the insertion position and the standby position can also be different. For example, the tube replacement device can standby at a second predetermined position near the winding mechanism and replace the tube at a third predetermined position.

[0085] In some embodiments, the loading position refers to, for example, the position where the tube is loaded (or stored) into the tube magazine of the tube updating device, and this position can be far from the insertion device or the standby position. For example, at the loading position, the tube magazine can be made more upright so that the tube to be loaded (stored) can automatically slide into the tube magazine due to gravity, thus simplifying the operation of storing the tube in the tube magazine.

[0086] In addition, one or more of the insertion position, the standby position, and the loading position can be set according to actual needs. For example, only the insertion position and the loading position can be set, or only the insertion position and the standby position can be set, or the insertion position, the standby position, and the loading position can be set, or more positions can be set, etc. The present application is not limited thereto.

[0087] In some embodiments, the tube replacement device moves from the loading position to the insertion position when receiving a control instruction; or, the tube replacement device moves from the loading position to the insertion position during the spinning process; or, the tube replacement device moves from the loading position to the insertion position after storing the tube and remains at the insertion position when there is a tube in the tube replacement device.

[0088] Thereby, the tube replacement device can reach the insertion position (standby position) in advance before the interruption of the spinning process, so as to save the time for replacing the tube, further accurately control the timing of replacement, and improve work efficiency.

[0089] For example, at any suitable moment during the spinning process, the tube replacement device can move to the insertion position and wait for the interruption of the spinning process so as to immediately insert the tube into the bobbin holder of the winding mechanism after the yarn bobbin pops out. Since after the interruption of the spinning process, the tube magazine does not need to move from the loading position to the insertion position, time can be further saved.

[0090] For another example, as Figure 3 shown, assume that the tube replacement device 202 is at the loading position at this time. When receiving the control information, the tube replacement device 202 moves from this loading position (for example, rotates or translates,Figure 3 Take rotation as an example) to the introduction position at a predetermined distance from the winding mechanism 2011 (for example, rotate downward as shown by the arrow in Figure 3 ). At this introduction position, the tube replacement device 202 is docked with the guide rail of the winding mechanism 2011 that can guide the empty tube.

[0091] For another example, after the yarn bobbin on the winding mechanism 2011 is ejected (for example, sent to the conveyor belt), the tube replacement device 202 ejects the stored tube (for example, ejects the frontmost tube through a pressure mechanism, and specific reference can be made to the related art), and configures the tube (for example, imports it through the guide rail) onto the winding mechanism 2011. For the related mechanisms for realizing actions such as ejection, conveyance, ejection, configuration, and import, reference can be made to the related art, and details will not be elaborated here.

[0092] In some embodiments, the control device detects whether a tube is configured on the winding mechanism 2011. When the tube is correctly configured on the winding mechanism 2011, a control instruction to start producing and winding yarn is sent to the yarn machine workstation 201.

[0093] For example, through a detector or the like, it can be detected whether a tube is configured, or whether it is configured at the correct position, etc. When the tube is correctly configured on the winding mechanism 2011, the subsequent yarn production and winding are continued; when the tube is not correctly configured on the winding mechanism 2011, the import of the tube can be waited for; when the tube is still not correctly configured after a predetermined time, an alarm can be issued to notify the relevant personnel.

[0094] Thus, through the detection of the control device, the timing for the winding mechanism to work again can be accurately determined, further improving safety and work efficiency.

[0095] In some embodiments, when the tube is correctly configured on the winding mechanism 2011, the control device also sends a control instruction to the tube replacement device 202 to move the tube replacement device 202 back from the introduction position to the loading position or the standby position.

[0096] Thus, through the detection of the control device, the timing for the tube replacement device to standby and introduce can be accurately determined, further improving safety and work efficiency. In addition, after the tube replacement device moves back to the loading position or the standby position, better maintenance and tube loading can be carried out.

[0097] The above embodiments only exemplarily illustrate the embodiments of the present application, but the present application is not limited thereto, and appropriate modifications can also be made on the basis of the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0098] In addition, the above only gives exemplary descriptions of each device or component, but the present application is not limited thereto. The specific content of each device or component can also refer to the related art; in addition, devices or components not shown in the figure can be added, or Figures 1 to 4 one or more devices or components in Figures 1 to 4 the figure can be reduced.

[0099] It should be noted that the above only gives exemplary descriptions of the embodiments of the present application, but the embodiments of the present application are not limited thereto, and appropriate modifications can also be made on the basis of the above various embodiments. In addition, the above only gives exemplary descriptions of each component, but the embodiments of the present application are not limited thereto. The specific content of each component can also refer to the related art; in addition, components not shown in the figure can be added, or one or more components in the figure can be reduced.

[0100] The embodiments of the present application also provide a control method for single-end doffing.

[0101] Figure 5 is a schematic diagram of the control method for single-end doffing according to the embodiments of the present application. As Figure 5 shown, the method includes:

[0102] 501. When the tube on the winding mechanism in the yarn machine workstation is wound into a yarn bobbin of a predetermined size, the control device sends control information for instructing to replace the yarn bobbin on the winding mechanism; and

[0103] 502. When the tube replacement device receives the control information, it uses the stored tube to replace the yarn bobbin on the winding mechanism.

[0104] Thus, by replacing the yarn bobbin on the winding mechanism with the tube stored in the tube replacement device, the yarn bobbin can be automatically replaced with an empty tube after the yarn winding is completed, reducing or avoiding manual intervention, lowering the maintenance cost, and improving the safety and work efficiency.

[0105] Figure 6 is another schematic diagram of the control method for single-end doffing according to the embodiments of the present application, showing a relatively complete process of single-end doffing. As Figure 6 shown, the method includes:

[0106] 601. The yarn machine workstation produces yarn and winds the yarn using a tube;

[0107] 602. The control device determines that the tube is wound into a yarn bobbin of a predetermined size;

[0108] For example, the length of the yarn on the yarn bobbin reaches a predetermined length, or the weight of the yarn bobbin reaches a predetermined weight, or the diameter of the yarn bobbin reaches a predetermined diameter, or the length of the yarn bobbin reaches a predetermined length, and so on. The above doffing conditions can be used alone, or two or more doffing conditions can be combined.

[0109] 603. The control device sends control information for instructing replacement of the yarn bobbin to the bobbin changing device.

[0110] In some embodiments, upon receiving the control information, the bobbin changing device moves from the loading position to the introduction position at a predetermined distance from the winding mechanism. For example, after the bobbin changing device reaches the introduction position, it can wait for further instructions, and in addition, it can also start the preparation work for replacement. This application is not limited thereto. For example, the bobbin changing device can also reach the introduction position at any appropriate moment.

[0111] 604. The control device sends a control instruction to stop winding to the yarn machine workstation, and causes the yarn bobbin to pop out from the winding mechanism onto the conveyor belt.

[0112] For example, after receiving the control instruction, the yarn machine workstation can cut the yarn and transfer the yarn bobbin to the conveyor belt for subsequent process flows. In addition, the control device can send a further instruction to the bobbin changing device to cause the bobbin changing device to start the replacement of the bobbin.

[0113] 605. After the yarn bobbin on the winding mechanism is popped out, the bobbin changing device pushes out the stored bobbin and configures the bobbin onto the winding mechanism.

[0114] As Figure 6 shown, the method may further include:

[0115] 606. The control device detects whether the bobbin is correctly configured on the winding mechanism. If the bobbin is correctly configured onto the winding mechanism, the control device sends a control instruction to start production and wind yarn to the yarn machine workstation, causing the yarn machine workstation to continue to execute 601. In addition, the control device can also send a control instruction to the bobbin changing device to cause the bobbin changing device to execute 607. If the bobbin is not correctly configured onto the winding mechanism, 608 is executed.

[0116] 607. The bobbin changing device moves back from the introduction position to the loading position or the standby position.

[0117] 608. Continue to wait or send an alarm message.

[0118] It should be noted that the above appendix Figure 5Or 6 only schematically illustrates the embodiments of the present application, but the present application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted. In addition, some other operations can be added or some of the operations can be reduced.
