Implementations of the embodiments of this disclosure shall be described below with reference to the accompanying drawings.
An embodiment of this disclosure provides a single doffing device, including a spinning machine workstation, a control apparatus and a tube replacement apparatus.
FIG. 1 is a schematic diagram of the spinning machine workstation of the embodiment of this disclosure. As shown in FIG. 1, the spinning machine workstation 100 includes a spinning mechanism 101 and a winding mechanism 102. The spinning machine workstation 100 is used for producing a yarn 11, and the winding mechanism 102 is used for winding the yarn 11. As shown in FIG. 1, a yarn take-off device 103 may be provided between the spinning mechanism 101 and the winding mechanism 102.
As shown in FIG. 1, the winding mechanism 102 may be configured with a tube 1021. The yarn 11 may be cross-wound on the tube 1021to form a bobbin 1022. The winding mechanism 102 may be separately driven by a driver, and may include a conveyor belt for conveying the bobbin 1022, and reference may be made to related techniques for detailed contents of the winding mechanism 102.
As shown in FIG. 1, the spinning machine workstation 100 may be controlled by a computer workstation 12, and the computer workstation 12 may control actions of components of one or more spinning machine workstations 100. The control apparatus in the embodiment of this disclosure may be implemented by, for example, the computer workstation 12 shown in FIG. 1; however, this disclosure is not limited thereto, for example, the control apparatus may also be one or some control circuits configured in the spinning machine workstation 100 or other devices.
It should be noted that the spinning machine workstation of this disclosure is only schematically described in FIG. 1; however, this disclosure is not limited thereto. For example, other components or devices may also be provided, and reference may be made to related techniques for details, which shall not be described herein any further. And reference may be made to related techniques for those parts or elements (such as a control line, and a connection element) that are not specified in FIG. 1, which are not limited in this disclosure.
FIG. 2 is the schematic diagram of the single doffing device of the embodiment of this disclosure, in which the control apparatus is omitted. FIG. 3 is a partial schematic diagram of the single doffing device of FIG. 2, showing a case of a winding mechanism of one spinning machine workstation and one tube replacement apparatus. And FIG. 4 is another schematic diagram of the single doffing device of FIG. 2, showing a case viewed from a side.
As shown in FIGs. 2-4, the single doffing device 200 may include a spinning machine workstation 201 and a tube replacement apparatus 202, and reference may be made to FIG. 1 for a structure of the spinning machine workstation 201. In FIGs. 2-4, for the sake of simplicity, reference number 201 is shown by taking one spinning machine workstation as an example.
The spinning machine workstation 201 has a spinning mechanism (not shown in FIG. 2) for producing a yarn and a winding mechanism 2011 for winding the yarn, wherein the winding mechanism 2011 is provided with a replaceable tube (as shown by 1021 in FIG. 1, not shown in FIG. 2) around which the yarn is wound.
When a yarn is wound into a yarn bobbin (as shown by 1022 in FIG. 1, not shown in FIG. 2) of a predetermined size around the replaceable tube on the winding mechanism 2011, the control apparatus (not shown in FIG. 2) transmits control information for instructing to replace the yarn bobbin on the winding mechanism 2011.
The tube replacement apparatus 202 stores one or more tube(s) therein, and replaces the yarn bobbin on the winding mechanism 2011 by using one of the stored tubes upon receipt of the control information.
In some embodiments, as shown in FIG. 2, for example, multiple spinning machine workstations 201 (for example, 12 spinning machine workstations configured at the front side are shown in FIG. 2), and one tube replacement apparatus 202 may be configured for each spinning machine workstation 201 (one tube replacement apparatus configured at the front side is only exemplarily shown in FIG. 2). One or more tube(s) may be stored in the tube replacement apparatus 202 (for example, 6 tubes may be stored in parallel). What described above are some examples of this disclosure only; however, this disclosure in not limited thereto.
Hence, the yarn bobbin may be replaced with an empty tube automatically after the yarn winding is completed by replacing the yarn bobbin on the winding mechanism with the tube stored in the tube replacement apparatus, thereby eliminating or avoiding artificial intervene, lowering maintenance cost, and improving security and operational efficiency.
It should be noted that the single doffing device of this disclosure is only schematically described in FIGs. 2-4; however, this disclosure is not limited thereto. For example, other components or devices may also be provided, and reference may be made to related techniques for details, which shall not be described herein any further. And reference may be made to related techniques for those parts or elements (such as a control line) that are not specified in FIGs. 2-4, which are not limited in this disclosure.
In some embodiments, the control apparatus transmits the control information to the tube replacement apparatus 202 in a case where a yarn length of the yarn bobbin (a total length of a yarn wound around the tube) reaches a predetermined length (a first length), or a weight of the yarn bobbin reaches a predetermined weight, or a diameter of the yarn bobbin reaches a predetermined diameter, or a length of the yarn bobbin (a length of the yarn bobbin itself) reaches a predetermined length (a second length).
For example, assuming that the diameter of the yarn bobbin 1022 shown in FIG. 1 reaches a pre-required diameter threshold, the yarn bobbin 1022 needs to be replaced. For example, the yarn length may be detected by a sensor of the spinning mechanism, and the diameter/length/weight of the yarn bobbin may be detected by the sensor of the winding mechanism, etc., and reference may be made to related techniques for specific detection components. This disclosure is not limited thereto, and the parameters as doffing conditions may also be, for example, a volume of the yarn bobbin, etc. In addition, the above doffing conditions may be used separately, or may be used by combining two or more of them.
Hence, a time for replacement may further be controlled exactly by the control apparatus, and operational efficiency may be improved.
In some embodiments, the control apparatus transmits a control instruction to stop winding to the spinning machine workstation 201 and causes the yarn bobbin to be ejected from the winding mechanism 2011 to a conveyor belt in a case where a yarn length of the yarn bobbin reaches a predetermined length, or a weight of the yarn bobbin reaches a predetermined weight, or a diameter of the yarn bobbin reaches a predetermined diameter, or a length of the yarn bobbin reaches a predetermined length.
For example, after the spinning machine workstation 201 receives the control instruction, it may deem that the winding of the yarn bobbin is completed, and hence production and winding of the spinning machine workstation 201 may be stopped, and replacement of the yarn bobbin may be prepared. For other spinning machine workstations 201, yarn production and winding may still be performed independently and are not affected by the control instruction.
Hence, the time for replacement may further be controlled exactly by the control apparatus, and operational efficiency may be improved.
In some embodiments, the tube replacement apparatus 202 pushes out one of the stored tubes at an introduction position and configures the tube on the winding mechanism after the yarn bobbin on the winding mechanism is ejected.
Hence, instructed by the control apparatus, the tube replacement apparatus and the winding mechanism operate in parallel (for example, the yarn bobbin is ejected, while the stored empty tube is introduced), the time for replacement may further be controlled exactly by the control apparatus, and operational efficiency may be improved.
In some embodiments, the introduction position refers to, for example, a position where an empty tube in the tube replacement apparatus may be inserted into a bobbin rack of the winding mechanism from a tube magazine, and the standby position refers to, for example, a position where the tube replacement apparatus waits for a tube replacement operation. The introduction position and the standby position may be in the vicinity of the winding mechanism and have predetermined distances from the winding mechanism.
The introduction position may be identical to the standby position, for example, the tube replacement apparatus may be standby at a first predetermined position near the winding mechanism and perform tube replacement at the first predetermined position; and the introduction position and the standby position may also be different, for example, the tube replacement may be standby at a second predetermined position near the winding mechanism, and may perform tube replacement at a third predetermined position.
In some embodiments, the loading position refers to, for example, a position where a tube is loaded (or stored) into the tube magazine of the tube replacement apparatus, which may be remote from the induction or standby position. For example, the tube magazine may be made more upright in the loading position, so that a tube to be loaded (stored) may automatically slide into the tube magazine due to the gravity, thereby simplifying operations of storing tubes by the tube magazine.
In addition, one or more of the introduction position, the standby position and the loading position may be set as actually demanded. For example, only the introduction position and the loading position may be set, or only the introduction position and the standby position may be set, or the introduction position, the standby position and the loading position may be set, and more positions may be set, etc., and this disclosure is not limited thereto.
In some embodiments, the tube replacement apparatus is moved from the loading position to the introduction position upon receiving a control instruction, or, the tube replacement apparatus is moved from the loading position to the introduction position during spinning, or, the tube replacement apparatus is moved from the loading position to the introduction position after storing the tubes, and remains at the introduction position when the tube(s) exist(s) in the tube replacement apparatus.
Hence, the tube replacement apparatus may reach the introduction position (standby position) before the spinning process is suspended, thereby saving time for replacing the tubes, further controlling exactly the time for replacing the tubes, and improving operational efficiency.
For example, at any suitable moment during the spinning process, the tube replacement apparatus may be moved to the introduction position, waiting for the spinning process to be suspended, so as to insert the tube into the bobbin rack of the winding mechanism immediately after the yarn bobbin is ejected. This may further save time as the tube magazine does not need to be moved from the loading position to the introduction position after the spinning process is suspended.
For another example, as shown in FIG. 3, it is assumed that the tube replacement apparatus 202 is currently at the loading position. In a case where the control information is received, the tube replacement apparatus 202 is moved from the loading position (such as being rotated or translated, and rotation is taken as an example in FIG. 3) to an introduction position with a predetermined distance from the winding mechanism 2011 (such as being rotated downwards as shown by the arrow in FIG. 3). In this introduction position, the tube replacement apparatus 202 is abutted with a guide rail of the winding mechanism 2011 capable of guiding an empty tube.
For a further example, after the yarn bobbin on the winding mechanism 2011 is ejected (such as being transferred to the conveyor belt), the tube replacement apparatus 202 pushes out the stored tube (such as pushing out a foremost tube by a pressure mechanism, and reference may be made to relevant techniques for details), and configures (such as introducing via the guide rail) the tube onto the winding mechanism 2011. Reference may be made to relevant techniques for implementing such actions as ejecting, transferring, pushing out, configuring, and introducing, which shall not be repeated herein any further.
In some embodiments, the control apparatus detects whether the winding mechanism 2011 is configured with the tube, and transmits a control instruction for starting producing and winding a yarn to the spinning machine workstation 201 in a case where the tube is correctly configured on the winding mechanism 2011.
For example, whether the tube is configured, or whether the tube is configured at a correct position, etc., may be detected by a detector. In the case where the tube is correctly configured on the winding mechanism 2011, subsequent yarn production and winding are proceeded; in a case where the tube is not correctly configured on the winding mechanism 2011, introduction of the tube may be awaited; and in a case where the tube are not properly configured after a predetermined time, an alert may be issued to notify relevant personnel.
Hence, with the detection by the control apparatus, the time for operation again of the winding mechanism may be exactly determined, and security and operational efficiency may further be improved.
In some embodiments, in the case where the tubes are correctly configured on the winding mechanism 2011, the control apparatus further transmits a control instruction to the tube replacement apparatus 202 to cause the tube replacement apparatus 202 to be moved from the introduction position back to the loading position or a standby position.
Hence, with the detection by the control apparatus, the time for standby and introduction of the tube replacement apparatus may be exactly determined, and security and operational efficiency may further be improved. Moreover, after the tube replacement apparatus is moved back to the loading position or the standby position, maintenance and loading of the tubes may be better conducted.
The above implementations only illustrate the embodiment of this disclosure. However, this disclosure is not limited thereto, and appropriate variants may be made on the basis of these implementations. For example, the above implementations may be executed separately, or one or more of them may be executed in a combined manner.
In addition, the devices or components are illustrated above only. However, this disclosure is not limited thereto, and reference may be made to related techniques for detailed contents of the devices or components; and furthermore, devices or components not shown in FIGs. 1-4 may be added, or one or more of the devices or components in FIGs. 1-4 may be reduced.
It should be noted that the embodiments of this disclosure are only illustratively described above. However, the embodiments of this disclosure are not limited thereto, and appropriate variants may be made on the basis of the above implementations. In addition, the components are illustrated above only. However, the embodiments of this disclosure are not limited thereto, and reference may be made to related techniques for detailed contents of the components. Moreover, components not shown in the drawings may be added, or one or more components in the drawings may be reduced.

604: the control apparatus transmits a control instruction to stop winding to the spinning machine workstation, and causes the yarn bobbin to be ejected from the winding mechanism to a conveyor belt;
for example, after receiving the control instruction, the spinning machine workstation may cut off the yarn, and transfers the yarn bobbing to the conveyor belt for performing subsequent processes; and furthermore, the control apparatus may further transmit an instruction to the tube replacement apparatus, so as to cause the tube replacement apparatus to start replacement of the tubes;

607: the tube replacement apparatus moves back to the loading position to the standby position; and
608: the tube replacement apparatus continues to wait or issues alert information.
