Embodiments of the present invention will be described with reference to the accompanying drawings.

[Embodiment 1] FIG. 1 is a sectional view of the automatic winder 1, and FIG. 2 is a plan view of the automatic winder 1. As shown in the figure, the automatic winder 1 is a so-called cone-to-cone type in which a cone-shaped yarn feeding package is rewound into a cone-shaped winding package, and a multi-pile winding is installed on a machine base 2 in parallel. It is mainly composed of a taking unit 3, a supply line 4 provided along a front side F of the machine stand 2, and a recovery line 5 provided along a rear side B of the machine stand 2. The front side F means the side on which the worker 6 mainly works, and the rear side B means the opposite side.

The supply and recovery of the yarn supply to each winding unit 3 are performed as follows. First, the actual tray 8 on which the yarn supplying package 7 (actual cone 7) is placed is conveyed from the automatic package feeder 9 along the front side F of the machine base 2 by the supply line 4. Then, these actual trays 8 are supplied to each winding unit 3 from the front side F of the machine base 2. After that, the empty tray 11 that has been wound by the winding unit 3 and has become the empty cone 10 is discharged from the rear side B of the machine base 2, transported by the recovery line 5, and recovered by the automatic package feeder 9.

The supply line 4 is, as shown in FIG.
It is configured by a belt conveyor that is arranged to be slightly inclined from the front side F to the rear side B of the machine base 2. The actual tray 8 conveyed by this conveyor is guided by the take-in lever 12 to the package passage 13 of each winding unit 3. The take-in lever 12 rotates like an damper with one end as a fulcrum, and guides the actual tray 8 on the conveyor to the package passage 13.

The package passage 13 is provided in each winding unit 3
Each free roller 14 is formed so as to pass through from the front side F to the rear side B, and is arranged so as to be slightly inclined from the front side F to the rear side B. Therefore, the actual tray 8 guided to the package passage 13 is not supported by the machine base 2 due to its own weight.
It naturally moves from front F to rear B. In this package passage 13, a standby position 15 for waiting the actual tray 8 is provided.
And a winding position 16 for winding the yarn from the actual tray 8.

Engagement pins 17 for preventing movement of the actual tray 8 are provided at the standby position 15 and the winding position 16, respectively. These engagement pins 17 are inserted into the engagement holes provided at the bottom of the actual tray 8 to prevent the actual tray 8 from moving. The reason for providing the standby position 15 is that after the actual cone 7 on the actual tray 8 has been wound up at the winding position 16 to become an empty tray, the next actual tray 8 is immediately moved to the winding position 16. This is for continuous winding.

The yarn of the actual tray 8 at the winding position 16 passes through the balloon guide 18, the tensor, the splicer, etc., and comes into contact with the traverse drum 19 to be driven to rotate.
Is rewound. The winding package 20 is doffed by an automatic doffing device 21 that moves along the machine base 2 when fully wound, and is stored in the storage part 22 at the rear part. Instead, the automatic doffing device 21 sets an empty bobbin. It is supposed to do.

The actual cone 7 on the actual tray 8 at the winding position 16
When the empty tray 11 has been wound up, the empty tray 11 is discharged to the recovery line 5 with the engaging pin 17 removed. The recovery line 5 is composed of a belt conveyor horizontally arranged on the rear side B of the machine base 2. The empty tray 11 on this conveyor is conveyed to the package automatic yarn feeder 9 and replaced with the actual tray 8. Then, the actual tray 8 is again conveyed by the supply line 4.

In FIG. 2, 23 is a blower for producing high-pressure air consumed in each winding unit 3, and 24 is a control for controlling each winding unit 3, the engaging pin 17, the take-in lever 12, and the like. It is a unit.

The operation of this embodiment having the above configuration will be described.

The actual tray 8 is a package automatic yarn feeder 9
Is conveyed along the front side F of the machine base 2 through the supply line 4 and is appropriately guided to the package passage 13 of each winding unit 3 by the take-in lever 12. And the real tray 8
Is waited at the waiting position 15 of the package passage 13 and wound at the winding position 16. Then, after becoming an empty tray 11, it is discharged to the collection line 5 and collected by the package automatic yarn feeder 9.

In this way, the supply line 4 is provided on the front side of the machine base 2.
Since the machine 6 is provided, the operator 6 can work from the front side F of the machine base 2 when changing the product type or handling a trouble (tray feeding abnormality).
It is not necessary to go around the rear side B of the machine base 2 as in the conventional case. That is, when the product type is changed, the actual tray 8 on the supply line 4 or the actual tray 8 at the standby position 15 of the package passage 13 is changed.
However, since all of these actual trays 8 face the front side F of the machine base 2, the operator 6 only has to work from the front side F of the machine base 2.

As a result, the worker 6 performs not only normal work but also all the processes including the product type change and the trouble process.
It can be performed from the front side F of the machine base 2. Therefore, the burden on the worker 6 is reduced, the time for changing the product type and the trouble processing is shortened, and the work efficiency and the production efficiency are improved.
