Embodiments of the present application will be described below with reference to the drawings.

The embodiment of the application provides a single-channel doffing device, which comprises a yarn machine workstation, a control device and a pipe replacing device.

Fig. 1 is a schematic view of a yarn machine workstation according to an embodiment of the present application. As shown in fig. 1, the yarn machine station 100 includes a spinning mechanism 101 and a winding mechanism 102; the spinning mechanism 101 is used for producing the yarn 11, and the winding mechanism 102 is used for winding the yarn 11; as shown in fig. 1, a yarn take-out 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 provided with a tube 1021, and the tube 1021 may cross-wind the yarn 11 to form a bobbin 1022; the winding mechanism 102 may be driven by a driver alone, and may also have a mechanism such as a belt for conveying the bobbin 1022, and the related art may also be referred to with respect to the details of the winding mechanism 102.

As shown in fig. 1, the yarn machine stations 100 may be controlled by a computer station 12, the computer station 12 controlling the operation of one or more of the individual components of the yarn machine station 100. The control device according to the embodiment of the present application may be implemented by, for example, the computer workstation 12 of fig. 1, but the present application is not limited thereto, and for example, the control device may be a certain control circuit or some other control circuits disposed in the yarn machine workstation 100 or in other devices.

It is to be noted that fig. 1 only illustrates schematically the yarn machine workstation of the present application, but the present application is not limited thereto; for example, other components or devices may be provided, and specific reference may be made to the related art, and the description thereof will be omitted. Reference may be made to the related art for components or elements (e.g., control lines, connection elements, etc.) not specifically identified in fig. 1, but which are not limited in this application.

Fig. 2 is a schematic view of a single-pass doffing apparatus according to an embodiment of the present application, in which a control device is omitted. Fig. 3 is a partial method drawing of the single-pass doffing apparatus of fig. 2, showing the winding mechanism of one of the yarn machine stations and one of the tube changing devices. FIG. 4 is another schematic view of the single-pass doffing apparatus of FIG. 2, shown from the side.

As shown in fig. 2 to 4, the single doffing apparatus 200 may include a yarn station 201 and a tube exchanging device 202, and the structure of the yarn station 201 may also refer to fig. 1. For the sake of simplicity, reference numeral 201 is shown in fig. 2 to 4 by way of example only for one yarn station.

The yarn machine workstation 201 has a spinning mechanism (not shown in fig. 2) for producing the yarn and a winding mechanism 2011 for winding the yarn; the winding mechanism 2011 is provided with a replaceable tube (1021 in fig. 1 and not shown in fig. 2) for winding the yarn.

When the tube on the winding mechanism 2011 is wound into a bobbin (shown as 1022 in fig. 1, not shown in fig. 2) having a predetermined size, the control device (not shown in fig. 2) transmits control information indicating replacement of the bobbin on the winding mechanism 2011.

The tube changing device 202 stores one or more tubes; upon receiving the control information, the tube replacement device 202 can replace the bobbin on the winding mechanism 2011 with the stored tube.

In some embodiments, as shown in fig. 2, for example, a plurality of yarn machine stations 201 may be provided (for example, fig. 2 shows that 12 yarn machine stations are provided on the front side), and one tube changing device 202 may be provided for each yarn machine station 201 (fig. 2 only shows that 1 yarn machine station is provided for example). One or more tubes (e.g., 6 tubes may be stored side by side) may be stored in the tube changing device 202. The above are only some examples of the present application, but are not limited thereto.

It is to be noted that fig. 2 to 4 only schematically illustrate the single-pass doffing apparatus of the present application, but the present application is not limited thereto; for example, other components or devices may be provided, and specific reference may be made to the related art, and the description thereof will be omitted. Reference may be made to the related art for elements or components (e.g., control lines, etc.) not specifically identified in fig. 2-4, which are not intended to be limiting.

In some embodiments, the control device sends the control information to the tube changing device 202 in a case where the length of the yarn of the bobbin (the total length of the yarn wound on the bobbin) reaches a predetermined length (first length), or the weight of the bobbin reaches a predetermined weight, or the diameter of the bobbin reaches a predetermined diameter, or the length of the bobbin (the length of the bobbin itself) reaches a predetermined length (second length).

For example, assuming the diameter of the bobbin 1022 shown in fig. 1 reaches a pre-desired diameter threshold, the bobbin 1022 needs to be replaced. The yarn length can be detected by a sensor of the spinning mechanism, the diameter/length/weight of the bobbin can be detected by a sensor of the winding mechanism, etc., for example, and the specific detecting member can refer to the related art. The present application is not limited to this, and the parameter as the doffing condition may be, for example, the volume of the bobbin or the like. The doffing conditions may be used alone, or two or more of them may be combined.

In some embodiments, the control device sends a control command to stop winding to the yarn machine workstation 201 and causes the yarn bobbin to be ejected from the winding mechanism 2011 onto the conveyor belt 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.

For example, after the yarn machine workstation 201 receives the control command, it may consider that the winding of the package has been completed, and therefore the yarn production and winding of the yarn machine workstation 201 may be stopped and the package replacement may be ready to be started. For the other yarn machine stations 201, yarn production and winding can still be performed independently and independently of the control commands.

In some embodiments, the tube changer 202 pushes out the stored tube at the introduction location and disposes the tube onto the winding mechanism after the bobbin on the winding mechanism is ejected.

Thus, the tube replacing device and the winding mechanism can be operated in parallel in cooperation with each other (for example, an empty tube stored can be introduced while ejecting a yarn package) by an instruction from the control device, and the timing of replacement can be controlled more accurately, thereby improving the work efficiency.

In some embodiments, the introduction position refers to, for example, a position where an empty tube in the tube changer can be inserted from the tube magazine into the creel of the winding mechanism, and the standby position refers to, for example, a position where the tube changer waits for a tube replacement operation. The introduction position and the standby position may be in the vicinity of the winding mechanism with a predetermined distance from the winding mechanism.

The introduction position may be the same as the standby position, for example, the tube replacement device may be standby at a first predetermined position in the vicinity of the winding mechanism and perform replacement of the tube at the first predetermined position; the introduction position and the standby position may be different, and for example, the tube replacement device may be standby at a second predetermined position near the winding mechanism and replace the tube at a third predetermined position.

In some embodiments, the loading position refers to, for example, a position where tubes are loaded (or stored) into a tube bank of the tube refreshing apparatus, which may be remote from the lead-in apparatus or the standby position. For example, the tube bank can be made more upright at the loading position, so that tubes to be loaded (stored) can automatically slide into the tube bank due to gravity, and thus the operation of storing tubes in the tube bank can be simplified.

Further, one or more of the introduction position, the standby position, and the loading position may be set according to actual needs. For example, only the introduction position and the loading position may be provided, only the introduction position and the standby position may be provided, the introduction position, the standby position, and the loading position may be provided, or more positions may be provided, and the present invention is not limited thereto.

In some embodiments, the tube changing device moves from the loading position to the introduction position upon receiving a control instruction; alternatively, the tube changing device is moved from the loading position to the introduction position during the spinning process; alternatively, the tube exchanging device is moved from the loading position to the introducing position after storing the tubes, and is held at the introducing position in a case where the tubes are present in the tube exchanging device.

For example, at any suitable point in the spinning process, the tube changing device can be moved into the introduction position, waiting for the spinning process to be interrupted, in order to insert the tube into the creel of the winding mechanism immediately after the yarn package has been ejected. Further time savings can be achieved since the magazine does not need to be moved from the loading position to the introduction position after the spinning process has been interrupted.

As another example, assume that tube exchange device 202 is now in the loading position, as shown in FIG. 3. Upon receiving the control information, the tube changer 202 moves (e.g., rotates or translates, fig. 3 exemplifies a rotation) from the loading position to an introduction position (e.g., rotates downward as indicated by the arrow in fig. 3) at a predetermined distance from the winding mechanism 2011. In the introduction position, the tube replacement device 202 abuts on a guide rail of the winding mechanism 2011 that can guide an empty tube.

For another example, after the bobbin on the winding mechanism 2011 is ejected (e.g., sent to a conveyor belt), the tube changer 202 pushes out the stored tube (e.g., the foremost tube is pushed out by a pressure mechanism, as described in the related art), and arranges (e.g., guides) the tube on the winding mechanism 2011. For the related mechanisms for implementing actions such as eject, transfer, push-out, configure, import, etc., reference may be made to related technologies, which are not described herein again.

In some embodiments, the control device detects whether a tube is arranged on the winding mechanism 2011 and, in the case of a tube correctly arranged on the winding mechanism 2011, sends a control command to start production and winding of the yarn to the yarn machine station 201.

For example, whether the outlet tube is arranged or not, or whether the outlet tube is arranged at a correct position, or the like can be detected by a detector or the like. With the tube correctly configured onto winding mechanism 2011, the following yarn production and winding continues; in the case where the tube is not properly arranged on the winding mechanism 2011, introduction of the tube may be waited for; in the event that the tube is not properly configured after a predetermined time has elapsed, an alarm may be issued to notify the relevant personnel.

In some embodiments, the control device also sends control instructions to the tube changing device 202 to move the tube changing device 202 from the introduction position back to the standby position or the loading position if the tube is properly configured onto the winding mechanism 2011.
