DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bobbin feeding device in an automatic winder.

[Conventional technology]

It is known to supply a winding unit with a full spinning bobbin (hereinafter simply referred to as bobbin) in place of an empty bobbin that has been wound in an automatic winder.

In some cases, a winding unit consisting of a traversing drum, a slab catcher, a winding pipe, a winding pipe support cradle, etc. rotates;
In some cases the winding unit is fixed, but in each case a bobbin is kept ready in the magazine for immediate replacement of a wound bobbin by a full bobbin. Various proposals have already been made for feeding bobbins into magazines either manually or automatically.

For example, a tubular supply device disclosed in Japanese Patent Application Laid-Open No. 52-49343 is known. That is, in the above-mentioned pipe supply device, a pipe holding cylinder fixed to a chain separates and transfers the pipe threads one by one, and supplies the pipe threads to a movable supply device (moving body). Transferring and receiving the yarn between the yarn supply device and the yarn holding device requires mutual positioning, which makes controlling each other's positions complicated, and increases the speed at which the yarn is supplied to the yarn supply device. There is a limit.

[Problem that the invention seeks to solve]

What is important when automatically feeding bobbins to a winding unit equipped with the above magazine is:
With the advent of high-speed winders, there is a bobbin supply capacity that can keep up with the winder's thread processing capacity.
Furthermore, there is a demand for the ability to install a bobbin supply device without modifying an existing factory winder.

An object of the present invention is to provide a bobbin supply device that can solve the above problems.

[Means to solve the problem]

The present invention is provided with a bobbin supply truck that runs along an automatic winder in which a plurality of winding units are arranged side by side, and a closed loop bobbin conveyance path for bobbin conveyance along the winding units, , a bobbin loading mechanism having a bobbin loading guide movable between the bobbin transport path and a bobbin loading position of the truck, a bobbin stocking section, and a bobbin loading mechanism for loading the stocked bobbins into a magazine on the winder side. By moving the bobbin take-in guide to the transport path where the bobbins are circulating, the bobbin replenishment from the bobbin transport path to the cart can be carried out at any position regardless of whether the cart is running or stopping. This is what I did.

[Effect]

The bobbin supply truck running along the winding unit takes in the bobbins transferred on the bobbin conveyance path regardless of whether it is running or stopped and stores them in the bobbin stock in the truck. In the unit,
The cart stops and the bobbin is loaded into the magazine.

Various doffing devices are applied, and the above doffing When installing the bobbin supply device according to the present invention in an existing winder having the device, it is only necessary to provide the supports 12, 13, etc. for laying the trolley running rails 4, 4, and nothing related to the existing winder body is required. No need to modify.

Next, an example of the bobbin supply cart 6 will be described.

4 and 5, the cart 6 includes a bobbin loading mechanism 14, a bobbin stock section 15, a loading mechanism 16 for loading the bobbin cut out from the stock section 15 into the magazine, and a bobbin loading mechanism 16 for loading the bobbin cut out from the stock section 15 into the magazine. It has a yarn end guide mechanism 17 etc. that guides the yarn end to a yarn end suction pipe in the center of the magazine. Further, the carriage 6 is equipped with a blower device 18 for processing yarn ends.

An example of the bobbin take-in mechanism 14 and the stock portion 15 is shown in FIGS. 5-7. That is, the stock portion 15 has a zigzag passage 1 having a width approximately equal to the length of the bobbin.
9, a bobbin receiving opening 20 is formed at the upper end of the passage, and a bobbin cutting rotating body 21 is provided at the lower part. Note that the opening 20 is located approximately on the same level as the bobbin conveyance surface 7a, or is located below the conveyance surface 7a, and is further provided close to the conveyor 7a.

On the side of the cart 6, there is a bobbin take-in guide 22 that is movable between the bobbin transport path 7a and the opening 20 position.
is provided. The guide 22 is a vertical plate 23, 2
4, 25 and an upper plate 26, it is a box-shaped body with an open lower part and bobbin entry side, and is moved in parallel between the solid line position 22 and the two-dot chain line position 22a in Figs. 5 and 6 by a link mechanism 27. do. That is, levers 32, 33 are connected by pins 34, 3 between the shafts 30, 31 of brackets 28, 29 fixed on the truck and the vertical plate 23.
One lever 32 is connected to a drive shaft 39 of a rotary solenoid 38 via bars 36 and 37.

When the feeler 41 of the bobbin detection feelers 40 to 42 arranged at appropriate positions of the stock section 15 in FIG. The bobbin B advances to the take-in position 22a on the conveyor path 7a, and the bobbin B, which is being transferred on the conveyor 7a in the direction of arrow 43 in FIG. 6, enters the box-shaped guide 22a. Thereafter, the guide 22a moves to the original standby position 22, so that the bobbin B moves from the conveyor 7a to the opening 20 of the truck 6 and falls into the stock section 15 to be housed therein.

In addition, in place of the box-shaped guide 22, a movable guide plate that can swing around a single axis is provided, so that when the guide plate is tilted and positioned on the conveyance path, the bobbin being transferred will be placed on the slope of the guide plate. It is also possible to be guided and fall into the stock part, 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 trolley 6 is currently traveling to the right of the solid line arrow 44, the bobbin detection sensor
Of the SR and SL, only the right sensor SR is ready for operation. In the winding unit 1i, 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 if there is no bobbin at even one position, the truck will decelerate. When the cart positioning sensor SU detects the identification mark Mi at a predetermined position of the unit, the cart stops at that position.
After this, the bobbin supply operation starts.

When the trolley 6 reaches the right end of the winder, the running direction switching/memory rod 45 is pushed by the stopper and is displaced to the position shown by the broken line, causing the dog D at the sensor SD position to separate from the sensor SD and reverse the running direction. However, among the bobbin detection sensors SR and SL, only the left sensor SL is in a detectable state.

The bobbins in the stock section 15 on the truck side are appropriately supplied to the magazine, and when the bobbin detection feeler (FIG. 5, 41) in the stock section detects that there is no bobbin, the bobbin take-in mechanism 14 on the top of the truck is activated to circulate the transport path. The bobbins in the ring are taken in one after another.

3 and 6, when the bobbin 6 is running leftward or rightward and a bobbin request signal is issued from the feeler, the rotary solenoid 3 of FIG.
8 operates to take in the bobbin. The bobbins B on the conveyance path 7a are arranged at regular intervals l1 by arrows 46
When the bobbin being transferred is taken in, a certain pitch l is placed on the conveyor 7b on the return trip.
With a spacing of 1, there may be cases where no bobbin is placed, and between one bobbin and the next bobbin there is a gap of 2×l1,
3×l1, . . . are transferred at random intervals that are an integral multiple of the distance l1. Therefore, for example, a bobbin detection sensor SB is provided near the chute 47,
A certain period of time after the bobbin passes the sensor SB position, that is,
If the sensor SB does not detect a bobbin even after the time corresponding to the distance l1 has elapsed, a bobbin request signal is immediately sent to the pickup device 8 to feed the waiting bobbin onto the conveyor 7b. Bobbins are always supplied on the conveyor 7a at constant intervals l1, and no missing bobbins occur.

In FIG. 3, the length of the outward path 7a of the transport path 7 is set so that the traverse range T of the cart 6 is within the length of the transport path 7. In addition, in FIG. 6, when the bobbin is taken in, if the bobbin is placed in the position at the moment when the guide body 22 protrudes toward the conveyance path side, the vertical plate 25 of the guide body will push the bobbin to the side opposite to the opening 20 of the cart. When the guide body 22 protrudes, a photoelectric sensor detects the presence or absence of a bobbin on the conveyor at the relevant position.
SS will be established. That is, while the sensor SS is detecting the bobbin, the rotary solenoid 38 is controlled by a control circuit (not shown) such that driving is blocked.

In the manner described above, bobbins are supplied to the magazine of the winder and also to the cart 6.

Note that in the above embodiments, one winder winds one type of bobbin, but one winder winds one type of bobbin.
The present invention is also applicable to the case where there are multiple types of bobbins to be processed by a single winder. For example, if one winder is divided into two parts, and one winding unit group winds yarn of type A, and the other group winds yarn of type B, in this case, the bobbin conveyance path is similar to that shown in Figure 3. Conveyors are provided in two stages, upper and lower, and two bobbin supply carts 6 as shown in Fig. 2 are provided, and the openings for taking in bobbins of each cart are provided at different heights, and one of the carts is exclusively connected to the upper closed loop conveyance path. What is necessary is to supply bobbins of type A to be transported to the other carriage, and to exclusively supply bobbins of type B, which are transported through the lower closed loop conveyance path, to the other truck.

〔Effect of the invention〕

As described above, in the present invention, bobbins can be automatically supplied to an existing winder equipped with a magazine without any modification, and furthermore, bobbins can be supplied while the cart is running, making it possible to supply bobbins extremely efficiently. supply is possible.

Furthermore, since a bobbin take-in guide for taking in the bobbin on the conveyor is provided on the cart side, the bobbin on the conveyor can be taken in at any position regardless of whether the cart is stopped or running. Since there is no need to closely control mutual positions,
You can quickly replenish bobbins to the cart.
