In addition, the tray 12 that has been emptied after the bobbin is removed is transported to the bobbin supply unit 5 via the bobbin transport path, and a new actual bobbin 11 is mounted, and is again sent to the actual bobbin transport conveyor 1A. It is.

  The empty bobbin discharge conveyor 1 </ b> B is a conveyance conveyor constituted by the flat belt 2, and the tray 12 conveyed on the conveyance conveyor enters the bobbin processing line 3 while being guided by a guide member (not shown). An empty bobbin is detected by detecting whether it is an empty bobbin 11e, a half bobbin 11h having a residual yarn, or a bobbin 11b with a minimal residual yarn by a tray residual yarn detection device (not shown) disposed on the bobbin processing line 3. 11b or the bobbin 11b with minimal residual yarn is pulled out by the bobbin pulling portion 4, and dropped into the box BB placed in front of the bobbin pulling portion 4, for example, and collected. Further, the half ball bobbin 11h is sent to the outlet 6 as it is and reused.

  The empty tray 12 is further transported through the bobbin processing line 3 and transported to the bobbin supply unit 5. The bobbin supply unit 5 is a unit that separates and drops the actual bobbins 11 one by one by a bobbin supply device BA such as a vibration-type parts feeder, and drops and mounts them on the tray 12. The tray 12 with the actual bobbin 11 inserted is supplied to the actual bobbin transport conveyor 1A, which is a transport path for transporting the bobbin to each winding unit, with the yarn end being spouted via the spout unit 6. Is done.

  The outlet unit 6 is provided with an outlet device 10 to be described later. The outlet device 10 cuts the bottom bunch wound around the bottom of the actual bobbin 11 and the backwind yarn wound around the outer periphery of the bobbin yarn layer. In addition, a lead-out process is performed in which a predetermined length of the bobbin thread end is inserted into the top hole of the bobbin so that automatic winding can be performed by each winding unit of the automatic winder W. In addition, the bobbin that could not be extracted is sent to the bypass line 7 and subjected to extraction processing again.

  The actual bobbin 11 that has been successfully subjected to the lead-out process is conveyed to the actual bobbin conveyor 1 </ b> A while being erected on the tray 12. The tray 12 transported by the actual bobbin transport conveyor 1A is transported to each winding unit of the automatic winder W.

  The bobbin supply unit 5 is provided with detection means SA for detecting the bobbin supplied from the bobbin supply device BA. The bobbin extraction unit 4 includes an empty bobbin 11e, a half-bob bobbin 11h, a bobbin 11b with a minimal remaining yarn, and the like. Detection means SB for detecting the bobbin is provided.

  Control of each member disposed in the bobbin processing unit C and control of driving and stopping of bobbin conveying means such as the actual bobbin conveying conveyor 1A and the empty bobbin discharging conveyor 1B are set in the control unit 10D as a driving program in advance. Can be kept. For example, the detection signals from the detection means SA and SB are input to the control unit 10D, and the driving and stopping of the actual bobbin transport conveyor 1A and the empty bobbin discharge conveyor 1B are controlled based on the result. .

  Next, the package winding operation in each winding unit will be described with reference to FIG. The bobbin 11 transported to the winding unit u1 via the actual bobbin transport conveyor 1A is guided by the guide plate 13, 14, 15 of the winding unit u1 to the tray 12 and transferred to the rotary disk 22 from the bobbin intake port 16. It is introduced into the bobbin standby path 18 and reaches the winding position 23.

  Due to the pressure air ejected from the nozzle 21, the yarn end pulled out from the bobbin 11 placed at the winding position 23 is blown up above the bobbin. The spliced yarn end is sucked and held by the intermediate pipe 24, swung upward, spliced to the package side yarn end by a yarn splicing device (not shown), and wound around the package 26 while being traversed by the traverse drum 25.

  When a full bobbin is stored in the bobbin standby path 18, the surplus bobbin interferes with the rearmost tray that is full and is not taken into the bobbin standby path 18, and is fed from the delivery port 17 to the actual bobbin conveyor 1 </ b> A. Is conveyed to the next winding unit. The bobbin that has been rewound at the winding position 23 is discharged to the bobbin discharge path 19 by the lever 20 and sent to the empty bobbin discharge conveyor 1B.

  The actual bobbin transport conveyor 1A has a configuration of a circle conveyor that circulates all the winding units, and can be configured to reserve excess actual bobbins that are not taken into any winding unit. Yes.

  Next, the mouthing device 10 installed in the mouthing unit 6 will be described with reference to FIG.

  The spouting device 10 is a yarn end processing device for pulling out the yarn Y from the actual bobbin 11 and supplying it to each winding unit of the automatic winder W, and the yarn Y from the actual bobbin 11 stopped at a predetermined position. A suction pipe 10A that is sucked and pulled out, a different number detection sensor 10B that detects the thickness of the yarn Y sucked by the suction pipe 10A, and a yarn that is disposed in the middle of the suction pipe 10A and cuts the yarn in the suction pipe. And a cutter 10C. Further, a predetermined yarn count is set in advance via the control device 10D, and a predetermined control is performed by comparing the set yarn count with the yarn count corresponding to the thickness of the thread Y to be sucked. .

  A cylindrical body 10F is attached to the lower part of the cutter 10C via an elastic bellows hose 10E. The cylindrical body 10F has an inner diameter that can be reciprocated up and down along the bobbin winding surface of the outer layer of the actual bobbin 11, and is lowered via a slide guide 10H that is slid by the cylinder 10G. The yarn end at the end of winding is sucked from the 11 winding surface and lifted to the standby position while unwinding as it is.

  The yarn Y is detected by a different number detection sensor 10B provided in the upper horizontal portion through the suction pipe 10A bent into an L shape. At this time, the yarn Y is guided to a predetermined position by the V-shaped groove of the guide plate 10M provided at the bent portion of the suction pipe 10A. For this reason, the yarn Y is quickly and easily sucked by a suction flow such as a blower connected to the suction pipe 10A without being in close contact with the inner wall of the suction pipe 10A near the bent portion.

  After the yarn number detection sensor 10B detects the presence of the yarn Y guided by the guide plate 10M and regulated at a predetermined position, the suction of the different count detection sensor 10B is continued for a predetermined time, and the yarn presser lever 10J is moved by the actuator 10K. Driven to stop the unwinding (suction) of the yarn Y so as to press the yarn Y against the top of the bobbin. The yarn 10 is cut by driving the cutter 10C in a state where the suction of the yarn Y is stopped.

  The cutter 10C that cuts the yarn Y is a so-called shutter cutter, and when the yarn Y is cut, the movable blade blocks the inside of the suction pipe 10A to prevent suction. Therefore, in a state where the cutter 10 </ b> C is operated, the yarn Y is cut and a suction force does not act on the yarn Y connected to the actual bobbin 11. In this state, when the suction means 10L provided at the lower portion of the tray 12 is operated, a suction force is generated in the top hole of the bobbin through the air flow path 12a drilled so as to penetrate the center portion of the tray 12. The cut yarn Y is dropped and sucked into the top hole of the bobbin.

  When the cut yarn Y is sucked into the top hole of the bobbin, the yarn presser lever 10J is holding the yarn Y, so that it is not pulled out any further, and the length to the position where the yarn Y is cut. The thread will be sucked. Therefore, the cutter 10C is disposed at a position corresponding to the required suction length.

  As described above, the different count detection sensor 10B that detects the thickness of the yarn naturally also has a function of detecting the presence or absence of the yarn Y. Further, in order to detect the thickness of the yarn and determine that the yarn Y is a different count, it is necessary to detect that the thickness of the yarn is different continuously for a certain period of time. This is because spun yarns usually have partial yarn defects called slabs and neps. The above-mentioned partial yarn defect is a short thickness unevenness, and in the case of a different count, a long continuous thickness variation is detected. Control to determine whether is necessary.

  These yarn count setting and different count determination control are performed via the control device 10D. In addition, a configuration may be adopted in which a predetermined alarm is transmitted when it is determined that the yarn count corresponding to the thickness of the detected yarn Y is different from a preset yarn count. When it is determined that the corresponding yarn count is different from a preset yarn count, the suction time of the suction pipe 10A can be extended arbitrarily and controlled.

  Therefore, if it is set to send an alarm when a different yarn count is detected, the correct bobbin count or different yarn count can be detected immediately when the actual bobbin 11 supplied to the automatic winder W is processed. Therefore, it can be detected before being conveyed to each winding unit, and the fact can be notified to the operator.

  Further, if the suction time of the suction pipe 10A is extended by a predetermined time when an abnormal count is detected, the thickness of the thread at the end of bobbin winding varies and becomes thin or thick. Even if the yarn count is different, it is possible to perform control so that the suction is continued until the normal yarn count is detected by solving the fluctuation part, and the thickness of the yarn that becomes the normal yarn count Since the actual bobbin 11 from which the normal main winding portion is exposed can be transported after the yarn is detected, automatic operation is facilitated, which is preferable.

  Furthermore, by providing a bypass line for paying out a bobbin with a different count, when it is determined that the yarn count corresponding to the thickness of the detected yarn Y is different from the preset yarn count, the corresponding actual bobbin is It can also be configured to pay out to the bypass line. With this configuration, one operator can manage a plurality of automatic winders, and it suffices to go around every predetermined time and process the bobbins that have been paid out.

  As the bypass line, the above-described bypass line 7 for paying out the bobbin that could not be delivered may be used, or a dedicated bypass line for paying out the different bobbin may be separately provided. The payout to these bypass lines should be configured so that the yarn count is different from a preset count after suction for a predetermined time. In the case where other yarn is mixed in the end portion, the different count portion is unwound and can be conveyed to each winding unit as a bobbin having a normal main winding portion.

  The different count detection sensor 10B may be any sensor that can detect the presence / absence of the yarn Y and the thickness of the yarn, and may be a photoelectric sensor or a capacitive sensor including a light projecting unit and a light receiving unit.

  The above embodiment is an example of a bobbin conveying unit adapted to one bobbin conveying line for supplying one type of bobbin and winding a package. A plurality of bobbin conveying lines forming a closed loop are arranged in parallel. Thus, each bobbin conveyance line can be configured corresponding to a plurality of types of bobbins.

  Therefore, it is also possible to apply the mouthing device 10 according to the present invention to an automatic winder that winds a plurality of types of yarns. Each mouthing device is installed for each bobbin conveying line and controlled independently. What is necessary is just to be the structure to do.

  As described above, according to the present invention, in the automatic winder having the spout device and the bobbin conveying means, the suction pipe that sucks and draws the yarn from the actual bobbin around which the yarn is wound, and the thickness of the drawn yarn are detected. And a control device that performs a predetermined control by comparing a preset yarn count with a yarn count corresponding to the yarn thickness detected by the different count detection sensor. Because it is an unloading device, it is possible to detect different counts at the unloading unit, and it can detect and stop the conveyance before conveying to the take-up unit, preventing unnecessary conveyance and improving the driving efficiency of the automatic winder. Can be improved.

  Although it is possible to arrange both the different count detection sensor 10B and the cutter 10C between the actual bobbin 11 and the suction pipe 10A, the different count detection sensor 10B and the cutter 10C are both If the structure is arranged in the suction pipe 10A, it is preferable that the yarn count can be reliably detected and the yarn can be cut with the yarn Y sucked and held. Furthermore, since the suction pipe 10A containing all the devices can be installed immediately above the actual bobbin 11, the entire device can be made compact.

It is a side view which shows the extraction apparatus which concerns on this invention. It is a whole top view of an automatic winder provided with the opening device concerning the present invention. It is a perspective view which shows the winding unit of an automatic winder.
