After that, the 5 guide (22a) moves to the original standby position F'f (22), and the bobbin ([3) moves from the conveyor (7a) J2 to the opening (20) of the trolley (6). Then, it falls and is housed in the stock part (15).

In addition, in place of the box-shaped kite (22), a movable guide plate that can swing around a single axis is provided, and when the guide plate is positioned on the conveyance path at an angle, the bobbin being transferred is It is also possible to fall into the stock part while being guided by a surface, and various taking-in mechanisms can be applied.

Next, the operation of the bobbin supply system configured as above will be explained.

In FIG. 8, if the cart (6) is currently traveling to the right of the solid line arrow (44), the bobbin detection sensor (SR,
) (SL), only the right sensor (S11.) is in an operable state. Winding unit (November) If there is no bobbin in any of the bobbin storage cylinders at a specific position in the magazine, the sensor (SR,) detects the absence of bobbins in the order of position (3a) and position (3b), and However, if there is no bobbin, the truck will move at a reduced speed, and the truck positioning sensor (S [J) will detect the identification mark (M
By detecting i), it stops at the relevant position. After this, the bobbin supply operation starts.

Furthermore, when the trolley (6) reaches the right end of the winder, the running direction switching/memory rond (45) is pushed by the slider and is displaced to the position shown by the broken line, thereby moving the dog (1) at the sensor (SD) position. ) is separated from the sensor (81)), the running direction is reversed, and only the left sensor (SL) of the bobbin detection sensors (SIN•) (SL) becomes detectable.

The bobbin in the stock part (15) on the cart side is fed to the magazine 11 (11) as appropriate, and when the bobbin detection feeler (Fig. 5 (old)) in the stock part detects that there is no bobbin, the bobbin take-in mechanism (14) on the top of the cart is activated. When activated, the bobbins that are connected to the conveyance path are successively taken in.

In FIGS. 3 and 6, when the bogie (6) is traveling leftward or rightward and a bobbin request signal is issued from the feeler, the rotary solenoid (38) in FIG. 6 is activated to take in the bobbin. It is.

The bobbins (B) on the conveyance path (7a) are arranged at regular intervals (Jl
), and if the bobbins being transferred are taken in, there may be cases where the bobbins are not placed on the conveyor (7b) on the return trip at a constant pitch (11). , there are 2×1 between one bobbin and the next bobbin.
1.3×11, . . ., the distance is an integer multiple of the distance (11), and the distances are randomly generated. Therefore, for example, the bobbin detection sensor (
If the bobbin does not detect the bobbin even after the bobbin has passed the sensor (S) position for a certain period of time, that is, the time corresponding to the distance (11), the pick-up device (8) is installed. If a bobbin request signal is sent to the side and the waiting bobbin is supplied to the conveyor (71),
Bobbins are always supplied on the forward conveyor (7a) at regular intervals (ll), and no missing bobbins occur.

In addition, in Fig. 3, the traverse range (T
) is within the length of the transport path (7).
The length of the outward path (7a) is set. In addition, in FIG. 6, if the bobbin was in the position at the moment when the guide body (22) protrudes toward the conveyance path side during loading, the vertical plate (25) of the guide body would move the bobbin to the opening (20) of the cart.
), so that when the guide body (22) protrudes, a photoelectric sensor (SS) is provided to detect the presence or absence of a bobbin on the conveyor at that position. That is, while the sensor (SS) is detecting the bobbin, the rotary solenoid (38) is controlled by a control circuit (not shown) so that the drive of the rotary solenoid (38) is blocked.

In the following manner, bobbins (1) are fed to the magazine of the winder, and bobbins are also fed to the cart (6).

In the above embodiments, a case has been described in which one winder winds one type of bobbin, but the present invention is also applicable to a case where one winder processes a plurality of types of bobbins. For example, if one winder is divided into two parts, and one group winds yarn of type A and the other group winds yarn of type B, the bobbin conveyance path will be as shown in Figure 3. A similar conveyor” - bottom 2
Two bobbin feeding carts (6) shown in FIG. It is only necessary to supply one type of bobbin to the other truck, and to the other truck exclusively to supply bobbins of type B, which are transported through the lower closed-loop conveyance path.

〔Effect of the invention〕

As described above, in the present invention, bobbins can be automatically supplied to an existing winder with a magazine without any modification of the cutter, and furthermore, bobbins can be supplied while the cart is running, which is extremely efficient. Bobbin supply is possible.

Furthermore, since the bobbins are actively linked on the closed-loop bobbin transport path, bobbins can be smoothly supplied to the cart.・
