PURPOSE:To have an effective transport of bobbins through elimination of hand selection by holding bobbins exhausted from an automatic winder with a bobbin chuck of an elevating/sinking device and by selecting them with a bobbin guide while they are on the way of being sent to the tray from an elevated position. CONSTITUTION:If a bobbin B1 on a tray T1 is empty, that is informed as only sensors PS1 and PS3 being sensible, an elevating/sinking body 23 sinks from the position 23b shown by the dot and dash line down to the lowermost position, and a chucking piece 65 intrudes against resistance to the top part of this empty bobbin so as to hold it. With subsequent rotation of a chain 54, the chucking device rises also together with said elvating/sinking body 23 to take out the bobbin B1 from the tray T1. When the elevating/sinking body 23 comes up to neighborhood of its uppermost position, a cam piece 34 is put in engagement with a cam follower 38, and a motion is made from the position shown by the dot and dash line 38a to the one by the solid line. When, further, the elevating/sinking body 23 attains its uppermost position, the chucking piece 65 is opened to drop the held empty bobbin B1 to the dropping position Q in a guide plate 33, and then the bobbin is sent onto a conveyor 84 under the guidance of a guide 33c. Thus bobbins are automatically selected and fed to the spinning machine. |
