Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a bobbin sorting device, and more particularly to a device for sorting multi-product bobbins transported by trays.

[Prior Art] A bobbin selection device for selecting a product type by using the tray is provided in a transfer path formed by mixing and transferring various kinds of spinning bobbins and appropriately distributing them. ing.

As shown in FIG. 3, for example, the conveying path 2 that connects the spinning machine (not shown) and the automatic winder 1 includes the winding sections 3, 4,
It has a yarn feed path 6 formed along one side of the automatic winder 1 divided into 5, and a return path 7 formed on the opposite side.

A branch supply path 8 is connected to the tube thread supply path 6, and a groove gauge 10 provided in the branch section 9 allows each tray T to be connected.
According to the identification groove (not shown) formed in the above, the winding sections 3 ... 5 are mechanically sorted. Further, a bobbin removing device 11 is provided in the return path 7, and a bobbin selecting device 12 for selecting a tray T (spinning bobbin) for each kind of yarn is provided in the vicinity thereof.

This bobbin sorting device 12 is a color discrimination sensor (mark sensor) that senses the trays T that are color-coded according to the type of yarn.
Depending on the information, processing is performed such as passing through the station as it is to the next station or removing the spinning bobbin.

Then, among the trays T discharged from the respective winding units, the bobbins with residual thread are returned to the tapping device 13 of the tubular thread supply path 6 as they are, and the empty bobbin or the bobbin with minimal residual thread is a bobbin for each type of tubular thread. After being taken out by the extracting device 11 and replaced with a full bobbin, the bobbin is circulated to the yarn supplying path 6.

[Problems to be solved by the invention] By the way, such a color-coded tray T changes from the initial state due to stains, discoloration, adherence of cotton wool, etc. during repeated use, and therefore color discrimination is performed. There is a problem that an error occurs in the detection of the sensor.

In particular, for example, when divided into three colors of black, white, and blue, even if the detection division of black and white can be surely made, it is difficult to distinguish from the intermediate color of blue, and depending on the ordinary mark sensor, It may not be possible to sort.

Therefore, in view of the above circumstances, the present invention was devised to provide a bobbin selection device that can reliably perform the selection according to the color of the tray.

[Means for Solving the Problems] In the present invention, a metal plate is provided on a tray of a multi-product bobbin color-coded into a plurality of colors so as to be visually distinguishable, and a metal plate is provided on a tray whose color is difficult to identify by a color identification sensor. A detection means for detecting the presence / absence of a plate and a color discrimination sensor are installed.

[Operation] With the above configuration, the operator can identify all the bobbins by looking at the tray colors, and the color discrimination sensor identifies all the trays by the tray color. The detection means identifies the tray of a color that is difficult to identify by the color identification sensor depending on the presence or absence of the metal plate.

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 and FIG. 2 show an embodiment of the bobbin sorting device according to the present invention. The return path 7 of the automatic winder is shown in FIG.
It shows the case where it is installed in. In the figure, the same components as those in the related art are designated by the same reference numerals and the description thereof will be omitted.

This bobbin carrying device is provided with an iron plate 21 which is a metal plate on a tray T ₁ of a specific color, and a proximity switch 22 which is a detection means for detecting the presence or absence of the iron plate 21 and a mark sensor which is a color discrimination sensor
It is composed by making it adjacent to 23. In the present embodiment, three types of tube yarns (A, B, C) are respectively black,
A tray T that is color-separated into white and blue is used. Among these, a blue tray T ₁ is provided with an iron plate 21.

The iron plate 21 is formed in an annular shape and has an upper surface 24 of the disk portion of the tray T _1.
It is fitted in the recess 25 formed in the. And iron plate 21
The lower side is fixed to the tray T ₁ by the double-sided adhesive tape 26, and the upper side is exposed.

The proximity switch 22 is attached to a guide plate 27 forming the return path 7, and is held so as to face the upper surface 24 of the tray T conveyed by the belt conveyor 28. A bobbin removing device 29 also serving as a detection controller is provided downstream of the proximity switch 22 in the transport direction D.
The bobbin can be removed by a sensing signal from 22 and replaced with a full bobbin.

The mark sensor 23 is located below the proximity switch 22 so as to face the side surface 30 of the tray T and senses the color of the tray T. In this embodiment, the bobbin is exchanged by forming it so that black and white can be particularly distinguished, and sending the information to a tray guide member (not shown) provided on the downstream side in the transport direction D. It can be assigned to the A type processing station or the B type processing station (not shown).

In addition to this, the bobbin sorting device is engaged with a tray sensing (electrostatic capacitance type) switch 31 provided on the guide plate 27 on the opposite side of the proximity switch 22 and the tray T on both sides of the proximity switch 22 so as to sandwich the tray T. And a stopper 32 that operates. The tray detection switch 31 sends a signal to the bobbin removing device 29 when the tray is detected, and is detected by the proximity switch 22 at the timing when the tray T being conveyed is stopped at a predetermined position. Is definitely possible.

Next, the operation of this embodiment will be described.

The tray T having the spinning bobbin discharged from each winding section passes through the return path 6 and is stopped by the stopper 32. As shown in Table 1, first, the tray detection switch 31
Detects the presence of all trays T,
Determine the detection timing. And the mark sensor 23
Selection is performed according to the color classification of the tray T. That is, by sensing the white tray T and not the black tray T,
These are clearly separated and transported to each processing station.

Although it is difficult to distinguish the blue tray T ₁ by the mark sensor 23, the proximity switch 22 detects the iron plate 21 to distinguish the tray T ₁ of other colors. That is, the extraction device 29 is operated by the sensing signal of the proximity switch 22. The extracting device 29 extracts an empty bobbin of type C or a bobbin with a minimal residual thread from the tray T ₁ and replaces it with a full bobbin produced by a spinning machine.

In this way, since the iron plate 21 is provided on the blue tray T ₁ and the mark sensor 23 is provided with the proximity switch 22,
By looking at the tray T, the operator can easily confirm that different types of bobbins are not mixed in the predetermined winding section, and the proximity switch 22 identifies the blue tray T ₁ which is difficult to identify by the mark sensor 23. Therefore, it is possible to reliably select the three types of tube yarns (spinning bobbins) without being affected by stains on the tray T. That is, it is possible to reliably prevent mixed numbers and mixed products in the winding section.

Further, since the detection timing is determined by the tray detection switch 31, it is possible to prevent the detection error of the iron plate of the proximity switch 22.

Further, in the present embodiment, although shown as a processing station for processing bobbins of C type, various other sorting / conveying systems using this bobbin sorting device are conceivable. First, all bobbins are removed. And
After that, each tray T may be distributed to the full bobbin supply position. In any case, three types of trays can be discriminated at one place.

Further, as a method of fixing the iron plate 21 to the tray T ₁ , a double-sided tape may be used, or an adhesive may be used for fixing. Further, the material is not limited to an iron plate, and a plate made of any material may be used as long as it can be surely detected.

Furthermore, in the present embodiment, three types of bobbins are selected, but two types of bobbins may be provided with a black iron plate, for example, of black and white trays, so that the two types can be clearly distinguished. .

[Effects of the Invention] In short, according to the present invention, the following excellent effects are exhibited.

The operator can visually confirm that the bobbins are not mixed, and the color discrimination sensor and the detection means can reliably select a large variety of bobbins without being affected by the stains on the tray, and the mixed number in the winding section, Mixed varieties can be prevented.
