Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bobbin supply system, and more particularly to a bobbin supply system in which a spinning machine and a winder are connected by a common main conveying path for a plurality of pairs.

[0002]

2. Description of the Related Art A bobbin wound with a yarn spun by a spinning machine is generally rewound into a package having a size and shape suitable for a subsequent process while removing a yarn defect portion. The automatic winder used in this rewinding process is configured by arranging winding units of multiple weights side by side to form one winder, and the yarn drawn at high speed from the bobbins supplied to each unit is rotated by the drive drum. When the bobbin is wound up on the package and one bobbin disappears, the next bobbin is newly supplied and thread knotting is performed,
Winding is performed again.

In this way, a plurality of bobbins are supplied to obtain one full-roll package. The spinning unit of the spinning machine is 50 to 6 per one winding unit of the winder.
If 0 spindles are used, the spinning process and the rewinding process will operate efficiently as a whole.

Therefore, a highly efficient system in which a plurality of spinning machines and a plurality of winders are connected by a common main conveyance path (a closed loop formed by connecting a supply path and a return path) has been put to practical use. It was In this type of system, each winder is divided into several sections for every several units, and the actual bobbin for each section is provided between each section and the bobbin supply path for supplying bobbins from the main transport path to each winder. Reservoir brine (circulation line) is installed to circulate and store, bobbin of one kind is supplied to one section and wound up, and bobbin of one kind produced by another spinning machine is put into another section. There is known a bobbin transporting system for supplying (see, for example, JP-A-60-52475).

[0005]

However, in the above-mentioned conventional system, the kind of bobbin is identified by providing a sensor on the branch path from the bobbin supply path to each reserve brine to identify the reserve line. Although only one product is taken in each time, all bobbins taken in from the main transport path to the bobbin supply path of each winder will be taken in to one of the reserve lines. In some cases, the bobbin was taken into the reserve line excessively, which caused a jam. That is, when a bridge occurs at the confluence of the branch road and each reserve line, the pressure on the branch road side usually becomes large and the balance is lost and the bridge disappears, but the bobbin to the reserve brine is eliminated. If the intake is excessive, the pressure on the reserve-line side also increases at the same time, so the bridge cannot be resolved and a jam occurs.

The present invention has been made in consideration of the above circumstances, and it is possible to prevent the bobbin from being excessively taken into the reserve brine by controlling the taking-in of the bobbin from the main transport path to the bobbin supply path of each winder. It is an object of the present invention to provide a bobbin supply system that can be used.

[0007]

In order to achieve the above object, the present invention provides a main carrier path and an actual bobbin supply path branched from the main carrier path to supply an actual bobbin to a winder.
A reserve line , which is provided in the actual bobbin supply path and stores the actual bobbin, is connected to the actual bobbin supply path.
A bobbin supply system provided with a bypass <br/> and return the full bobbins bottle feed path to the main transfer path, provided in the reserve line, and Bobinsensa for detecting the number of bobbins on the reserve line, the When it is detected by the bobbin sensor that the number of actual bobbins on the reserve line is equal to or greater than a predetermined number, the bobbin removal that stops the supply of the actual bobbin taken from the main transport path to the actual bobbin supply path to the reserve line side is stopped. The bobbin take-in stop device is provided at a branch portion between the actual bobbin supply path and the bypass .

[0008]

[ Function ] The bobbin sensor is the actual bobbin on the reserve line.
When it is detected that the number is more than the specified number, the
The bobbin loading is stopped for the actual bobbin loaded in the bin supply path.
It is not transported to the reserve line by the device.
Then, it is returned to the main transport path through the bypass. In this way, even if a large number of bobbins are transported on the main transport path, the bobbin will not be taken into the reserve line where the number of bobbin storages is greater than the predetermined value, so the occurrence of jams is prevented. It Also, the main transport path and
Since the bobbin take-in stop device is provided at the branch portion with the Y-pass , the actual bobbin is conveyed without staying in the main conveyance path without being affected by the bobbin take-in stop device.
Therefore, the actual bobbin does not stay in the main transport path due to the stop of the supply of the actual bobbin to the reserve line.

Bobbin sensors BS1 to BS3 for detecting passage of bobbins are provided in the reserve brines RL1 to RL3 of C3, respectively. The output signals of the bobbin sensors BS1 to BS3 are input to the control device 4 incorporated in the CBF1.

Main transport path ML and actual bobbin supply path nl1
A bobbin take-in stopping device 2 is provided at a branching point of and. As shown in FIG. 3, the bobbin take-in stopping device 2 is provided with a color sensor CS1 provided near the upstream side of the branch portion of the actual bobbin supply path nl1 and the bypass 5, and an opening / closing unit at the entrance of the bypass 5. The main part is constituted by the gate G1. The color sensor CS1 is adapted to detect the color of the bobbin or the color of the mark attached to the tray for transporting the bobbin according to the type, and its output signal is also input to the control device 4. The driving device 3 for the gate G1 is composed of a color sensor CS1 and the bobbin sensors BS1 to BS.
Drive control is performed by the controller 4 based on a signal from the controller 3. That is, the control device 4 of the CBF 1 controls the drive of various mechanisms in the CBF 1 and also functions as a bobbin take-in control means. Main transport path M
The bobbin conveyed on L always enters the actual bobbin supply path nl1 once, and is taken into the downstream side of the actual bobbin supply path nl1 as it is when the gate G1 is open, and the
When the gate G1 is closed, it is sent to the empty bobbin return path nl2 through the bypass 5 and returned to the main transport path ML again.

The control unit 4 includes bobbin sensors BS1 to BS.
The signal from 3 is constantly monitored for a predetermined time (for example,
When the number of bobbins passing per bobbin on the brine (a time required for the bobbin to make one round) becomes a predetermined number (for example, 5) or more, the gate of the actual bobbin supply path including the reservoir brines RL1 to RL3 is closed. The bobbin intake to the actual bobbin supply path is stopped. In this case, the arithmetic unit 1 always detects the type of bobbin conveyed to the branching section by the color sensor CS1 of the bobbin intake stop unit 2 and the bobbin on the reserve brine in which the number of bobbin reservoirs has reached a predetermined number or more. Open and close the gate according to the variety.

For example, the reserve-line RL2 and RL
If the total number of bobbins for each of the three is greater than or equal to the predetermined number,
The control device 4 opens the gate G1 only when the A type is detected by the color sensor CS1 and closes the gate G1 when the other B and C types are detected (see FIG. 3 (b)). . As a result, there is still a margin in the reserve-line RL.
Only No. 1 is supplied with the required type A bobbin. Since the supply of bobbins to the reserve brines RL2 and RL3, which has already reached the predetermined number of bobbins, is stopped, jamming due to excessive intake of bobbins is prevented.

The case where a large number of bobbins are handled has been described above, but when only one type of bobbin is handled, it is not necessary to detect the bobbin type by the color sensor CS1.

[0019]

According to the above summary the present invention, it becomes without bobbin reservoir numbers already more bobbins to the reserve line that is a predetermined number or more is taken, be prevented the occurrence of a jam it can. Further , since the bobbin take-in stopping device is provided at the branch portion between the actual bobbin supply path and the bypass , the actual bobbin is not retained in the main transport path when the supply of the actual bobbin to the reserve line is stopped. Without, it can be transported soundly.
