Definitions

  • the present invention relates to improvements of an automatic winder for winding a yarn unwound from a supply bobbin into a package and its winding unit.
  • a conventional automatic winder comprises a plurality of winding units 4 arranged in a lateral direction corresponding to a conveyor conveying direction, between a supply bobbin conveyor 2 on a rear side E and an empty bobbin conveyor 3 on a front side F (an operation passage side), as shown in the side view in Figure 12.
  • Each winding unit 4 has a standing frame 6 supported tiltably on an underlying support pipe 5 and has a bobbin supply and ejection device 7, a yarn joining device 8, and a winding device 9 attached on the standing frame 6.
  • the standing frame 6 can be tilted between a winding position A where it is stood up and a tilted position C where it is tilted toward an operation passage side for maintenance and inspection.
  • Each winding unit 4 stops a supply bobbin B supplied from the supply bobbin conveyor 2, at an unwinding position D and then uses a winding device 9 to lift a yarn unwound from the supply bobbin B so as to form a package P.
  • the winding unit 4 is also configured so that the yarn joining device 8 joins ends of a yarn cut to remove a yarn defect and so that the bobbin supply and ejection device 7 ejects an empty bobbin B' to the empty bobbin conveyor 3.
  • the conventional winding unit 4 is assembled by an operator by attaching, to the single standing frame 6, parts constituting the bobbin supply and ejection device 7, the yarn joining device 8, and the winding device 9. Since, however, the large number of parts cannot substantially be simultaneously attached to the single standing frame 6, the assembly requires the parts to be sequentially attached, thereby increasing an assembly man hour. Furthermore, the winding unit 4 may require different parts depending on different specifications for a yarn or the like, thereby requiring a large amount of time and labor to select parts. Thus, there has been a demand for a reduction in assembly man hour.
  • the automatic winder 1 comprising the plurality of winding units 4 arranged between the supply bobbin conveyor 2 and the empty bobbin conveyor 3, to inspect an arbitrary winding unit 4 for maintenance while maintaining the operation of the other winding units 4, a tray guide (not shown in the drawings) must be attached instead of the bobbin supply and ejection device 7 tilted with the standing frame 6 for inspection and maintenance. Attachment and removal of the tray guide requires a large amount of time and labor.
  • the frequency of maintenance and inspection differs between the bobbin supply and ejection device 7 and the yarn joining device 8 and the winding device 9 and is higher with the yarn joining device 8 and the winding device 9.

  • a tilting center of the upper part may be located above the bobbin supply and ejection device.
  • the upper part may be pivoted to the lower part.
  • the yarn joining device and the winding device which are often inspected for maintenance, can be moved to a position where they can be easily inspected for maintenance. If the tilting center of the upper part is set above the bobbin supply and ejection device, it is higher than that of the conventional automatic winder, so that an angle through which the upper part can be tilted without hindering empty bobbins from being conveyed by the empty bobbin conveyor on the operation passage side can be increased above the tilting angle of the conventional automatic winder. Consequently, a winding unit to be inspected for maintenance can be drawn out further toward the operation passage. If the upper part is pivoted to the lower part, the lower and upper parts can be integrally handled.
  • Means employed by the present invention to operate when a pneumatic path provided between a base on which winding units are mounted and the tilting upper part is separated into two to tilt the upper part, to prevent pneumatic paths in other winding units from being affected by variations in pressure is an automatic winder, wherein one of a plurality of pneumatic paths with closing valves is provided in a base on which winding units are attached, the upper part includes a plurality of pneumatic pipes constituting the other pneumatic path, and a corresponding end of the other pneumatic path can be removably joined to an end of the one pneumatic path.
  • a valve operating member may be provided for simultaneously opening and closing the plurality of closing valves.
  • the other pneumatic pipe may be flexible.
  • the upper part can be tilted with the other pneumatic pipe while preventing pneumatic paths in other winding units from being affected by variations in pressure.

  • Means employed by the present invention to enable transmission between the lower and upper parts is an automatic winder, wherein one of a driving node and a driven node of a transmission mechanism is located in the lower part while the other is located in the upper part, and the driving and driven nodes are connected together when the upper part is located at the winding position and are mutually separated when the upper part is located at the tilted position.
  • the driving node is formed of a cam
  • the driven node is formed of a cam lever.
  • the nodes of the transmission mechanism when the upper part is located at the winding position, the nodes of the transmission mechanism are connected together to transmit power between the lower and upper parts.
  • the nodes of the transmission mechanism when the upper part is tilted toward the tilted position, the nodes of the transmission mechanism are mutually separated, the tilt of the upper part is affected by the transmission mechanism.
  • Means employed by the present invention to enable the yarn joining device and the winding device to be individually assembled is a winding unit for an automatic winder comprising a bobbin supply and ejection device, a yarn joining device, and a winding device all in a frame, wherein the frame can be divided into a frame lower part including the bobbin supply and ejection device, a frame intermediate part including the yarn joining device, and a frame upper part including the winding device.
