Embodiment Construction

[0033] Next, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a plan view showing the bobbin supply device 10 according to an embodiment of the present invention together with the tray conveying path 110 and the automatic winder 100. figure 2 It is a perspective view showing the overall configuration of the bobbin supply device 10.

[0034] In addition, in the following description, "upstream side" and "downstream side" mean the upstream side and the downstream side with respect to the conveying direction of the yarn supply bobbin 3 and the conveying tray (conveying member) 2.

[0035] figure 1 The illustrated bobbin supply device (bobbin supply system) 10 supplies a yarn supply bobbin 3 formed by winding a yarn on a core tube (winding tube) 4 to an automatic winder 100.

[0036] The automatic winder 100 includes a plurality of winder units 101 arranged side by side. Each winder unit 101 unwinds the yarn from the supplied yarn sup...

Abstract

The present invention relates to a yarn supply bobbin direction changing device and a bobbin supply system. The bobbin direction aligning device (6) aligns a yarn supply bobbin in which yarn is wound on a cylindrical core tube (4) having a bottom (4a) and a top (4b) with a smaller diameter than the bottom (4a). The direction of (3) is converted. The bobbin direction alignment device (6) is provided with a pair of core tube guide paths (63) formed obliquely. A bottom side receiving portion (71) and a top side receiving portion (72) are formed on each core tube guide path (63). The bottom side receiving portion (71) passes the top (4b) of the core tube (4) and receives the bottom (4a). The top side receiving part (72) is located on the downstream side of the bottom side receiving part (71) and receives the top part (4b). The bottom side receiving portion (71) is configured to open a receiving surface (84a) for receiving the end portion of the core tube (4) on the lower side.

Description

Technical field [0001] The present invention mainly relates to a yarn supply bobbin direction switching device that converts the direction of the yarn supply bobbin. Background technique [0002] Conventionally, in a bobbin supply system that supplies yarn supply bobbins to each winder unit of an automatic winder, it is known that the base of the individualized yarn supply bobbin (the side that can be mounted on the transport tray) faces The bobbin direction changing device that makes it fall in the downward state. Japanese Patent Application Laid-Open No. 2014-25191 discloses such a bobbin direction switching device. [0003] Japanese Patent Application Laid-Open No. 2014-25191 discloses a device for changing the direction of a bobbin or a bobbin. In this device, two accommodating parts provided with an intermediate chamber for accommodating one of the end parts of the bobbin (bobbin) are provided. The intermediate chambers are each set to a size such that the spool tip (smalle...
