According to above structure, the supply that winder unit 3a can accept for spool 21 (real bobbin) from Cylinder feeder path 95, and can will batch discharging towards bare bobbin transport path 96 for spool 21 (bare bobbin) after end.

Next, the detailed structure of the delivery tray 26 to present embodiment describes. As shown in FIG. 2 and 3, delivery tray 26 possesses bolt 26a, support 26b, base station 26c.

Bolt 26a is formed as being configured in the roughly bar-shaped projection on the top of delivery tray 26. The bottom of bolt 26a is formed as the roughly columned cylindrical portion 26p of diameter 20mm, and top is formed as roughly cone shape top ends 26q. And cylindrical portion 26p, so that along with approaching top (upper end), the mode that diameter reduces is gradually formed as taper, thus, is formed as being easy to inserting the structure of bolt 26a for spool 21. And the height h1 of the bolt 26a shown in Fig. 3 is 38mm, under the state that confession spool 21 is inserted in to bolt 26a, carry the structure that also can not deviate from from bolt 26a for spool 21 even if be formed as.

Support 26b is configured in and compares the bolt 26a position of side on the lower, is formed as diameter 28mm, that height h2 is 12mm is roughly cylindric. Support 26b configures in the axle center mode consistent with the axle center of bolt 26a. The diameter of the periphery of support 26b is larger than the diameter of the periphery of the lower end of bolt 26a, is formed with the smooth bobbin bearing-surface 26r of ring-type at the upper surface of this support 26b. Thus, in the situation that confession spool 21 is inserted in to bolt 26a, the lower surface that is formed as the core pipe that supplies spool 21 is equipped on the form of bobbin bearing-surface 26r, can stably carry. And this support 26b is formed as the size identical with the support 100b in the past shown in Figure 10, even if therefore also can use without any problems in existing spinning winder 1.

Base station 26c is formed on the bottom of delivery tray 26, is formed as diameter d 1 roughly cylindric for 60mm, height h3 are 15mm. Base station 26c configures in the mode consistent with bolt 26a axle center. Like this, because the diameter of base station 26c is less than base station 100c (diameter 70mm) in the past, the interval (specifically adjacent spindle axis 111,111 interval each other) that therefore delivery tray 26 of present embodiment can corresponding adjacent spinning unit 2a, 2a is configured narrow spinning frame 2. And from automatic bobbin winder 3 sides, can make increases at the maximum quantity for spool 21 (real bobbin) of Cylinder feeder path 95 standbies. Particularly, in delivery tray 100 in the past, maximum standby number is 2, by adopting the delivery tray 26 of present embodiment, just can make maximum standby number be increased to 3 without the structure that specially changes path panel 71. Thereby, even if in the case of temporarily stopping from the supply for spool 21 of spinning frame 2, also can make the operation of batching of the yarn of automatic bobbin winder 3 sides be difficult to interrupt.

In addition, preferably the diameter of base station 26c is below the above 65mm of 55mm. This be because: if the stability that the diameter of base station 26c is carried lower than 55mm reduce, on the other hand, if exceed 65mm delivery tray 26 compactedness reduce.

From the lower surface (lower surface of base station 26c) of delivery tray 26 till the height (the height h4 of Fig. 4) on the top of bolt 26a is 65mm, larger than the diameter d of base station 26c 1 (60mm). Therefore, can be at the diameter of guaranteeing in order to shorten base station 26c in supporting the length for the needed bolt 26a of spool 21.

In addition, preferably from the lower surface of base station 26c till the height on the summit of bolt 26a is below the above 70mm of 60mm. This be because: if height is difficult to stably support for spool 21 lower than 60mm, on the other hand, if exceed 70mm the center of gravity 26e of delivery tray 26 rise and the stability of carrying reduces.

In the delivery tray 26 of present embodiment, be formed with through hole 26d in the mode that penetrates into the top ends 26q of bolt 26a from the lower surface of base station 26c. Thus, can be blown into air from the downside of delivery tray 26, and the ejection opening 26s forming on the top of bolt 26a from through hole 26d blows afloat air, therefore can be easily from utilizing aforesaid thread guide devices 92a that loose thread is inserted in to yarn 20 being drawn for spool 21 (real bobbin) Fig. 7 auxiliary blows portion 28 of axis hole 21a state.

The opening 26t that through hole 26d forms at the lower surface of base station 26c is configured to the toroidal of diameter 30mm. Thus, opening 26t can be formed as to simple shape, and, in the conveying mechanism having at aforesaid spinning unit 2a, above-mentioned transfer unit can be inserted in to opening 26t and carry well.

Here, the diameter of the opening 26t of the lower surface of base station 26c is not limited to be formed as described above 30mm, but is preferably below the above 40mm of 25mm. Thus, can utilize above-mentioned conveying mechanism to carry without any problems delivery tray.

In addition, from suppressing the viewpoint of material cost, preferably through hole 26d is formed greatlyr, but along with the part of the inside that is formed at base station 26c in through hole 26d is that base station through hole 26f becomes greatly, the center of gravity of delivery tray 26 rises, and delivery tray 26 is formed as unsure state. For this point, in the delivery tray 26 of present embodiment, base station through hole 26f is formed as two stages cylindric in large footpath, path bottom, top as shown in Figure 3. Particularly, the diameter of the cylinder on the top of base station through hole 26f is 18mm, is highly 6mm, and the diameter of the cylinder of bottom is 30mm, is highly 9mm.

To sum up, in the time considering to have the cylinder (diameter is 60mm, highly is the cylinder of 15mm) of the diameter that equates with base station 26c and height, the volume of base station through hole 26f is 18.6% (volume of base station through hole 26f is 2511 π [mm3], and the volume of above-mentioned cylinder is 13500 π [mm3]) with respect to the volume of this cylinder. In other words,, by be formed with base station through hole 26f in base station 26c, the part suitable with 18.6% volume is by loss of weight. According to this structure, can suppress the material cost of delivery tray 26, and can guarantee that center of gravity 26e is lower.

In addition, preferably the volume (volume of base station through hole 26f) of the through hole 26d in base station 26c is more than 10% below 20% with respect to the volume of cylinder with the diameter that equates with base station 26c and height. This be because: if a little less than the minimizing effect lower than 10% material cost, on the other hand, if exceed, 20% center of gravity 26e rises and the stability of carrying reduces.

The height h5 of the center of gravity 26e of delivery tray 26 is positioned at from the lower surface of base station 26c the highly position for 15.4mm, be positioned near the height of upper surface of base station 26c (particularly, difference in height be ± 1mm in). And the height h5 of center of gravity 26e compares low the binary height of height h2 of delivery tray 26 (height of h4/2=32.5mm from lower surface), therefore, even if will load under the state of delivery tray 26 and also can stably carry for spool 21.

In addition, low in the position of center of gravity 26e, can stably carry delivery tray 26, on the other hand, once if because certain is former thereby lay across, become the only state of the outer peripheral face ground connection of columned base station 26c (state that float on the top of bolt 26a), exist delivery tray 26 to be rolled into the misgivings in a distant place. For this point, the height h5 of the center of gravity 26e of the delivery tray 26 of present embodiment is positioned at the position (near the position height of the upper surface of base station 26c) of 15.4mm from the lower surface of base station 26c, therefore, can make delivery tray 26 be difficult to topple over, and, even if bolt 26a is also easy to ground connection in the situation that delivery tray 26 is laid across, can easily rest near the place of rolling.

In addition, if the height of center of gravity 26e in the lower end from support 26b to upper end, can bring into play well the effect of the rolling that prevents as described above long distance. On the other hand, if the lower surface of the aspect ratio base station 26c of center of gravity 26e is high and lower than the upper surface of base station 26c, can obtain the stable and effect that is difficult to topple over of delivery tray 26. And, if the height of center of gravity 26e is positioned near the height of upper surface of base station 26c, can balance be prevented well effect and the stability-enhanced effect of the rolling of long distance.

In addition the molding synthetic resin that, preferably delivery tray 26 is polyformaldehyde by its principal component. Thereby the appropriate sliding having by material, can make delivery tray 26 be difficult to hooking in spinning unit 2a, winder unit 3a and pallet transport path 90 etc.

Compare the lower surface from base station 26c till the binary position of height h4 on the summit of bolt 26a is low the position of the center of gravity 26e of delivery tray 26.

Thus, can guarantee in order to support the length for the needed bolt 26a of spool 21, and can shorten the diameter of base station 26c, can increase can be at the maximum quantity of the delivery tray 26 of Cylinder feeder path 95 standbies. And, because the position of center of gravity 26e is low, therefore, in pallet transport path 90, can stably carry the delivery tray 26 being placed with for spool 21.

And in the delivery tray 26 of present embodiment, the diameter of base station 26c is 60mm.

Thus, in the Cylinder feeder path possessing at existing spinning winder 1, the maximum quantity that can allow to configure delivery tray 26 is increased to 3 from 2. Therefore,, even if in the case of temporarily stopping from the supply for spool 21 of spinning frame 2, also can make the operation of batching of winder unit 3a be difficult to interrupt. And, the spinning frame 2 that also can narrow corresponding to the interval of adjacent spindle axis 111,111.

And, in the delivery tray 26 of present embodiment, from the lower surface of base station 26c till the height h4 on the summit of bolt 26a is 65mm.

Thus, delivery tray 26 can support the confession spool 21 widely circulating as spinning frame use reliably.

And, in the delivery tray 26 of present embodiment, be formed with the through hole 26d at the lower surface opening of base station 26c. The volume (volume of base station through hole 26f) of through hole 26d in base station 26c is 18.6% with respect to the volume of the cylinder with the diameter that equates with base station 26c and height.

Thus, the conveying mechanism that spinning frame 2 possesses can move delivery tray 26 the opening 26t of the lower surface of the transfer unit insertion base station 26c of convex. And, the position of the 26e that can lower the center of gravity, and reduce material cost.

And in the delivery tray 26 of present embodiment, the opening 26t that through hole 26d forms at the lower surface of base station 26c is formed as the circle of diameter 30mm.

Thus, opening 26t can be formed as to simple structure.

And in the delivery tray 26 of present embodiment, through hole 26d is at the upper opening of bolt 26a. The opening 26t of the lower surface of base station 26c is connected by through hole 26d with the opening on the top of bolt 26a (ejection opening 26s).

Thus, can send into air towards the inside of the axis hole 21a for spool 21 from the downside of delivery tray 26. And, because through hole 26d connects delivery tray 26, therefore can suppress the material cost of delivery tray 26. And, because through hole 26d connects to the inside of bolt 26a, therefore can make bolt 26a lightness and the position of the 26e that lowers the center of gravity.
