Description

Bobbin processing device

Technical Field

The present invention relates to a bobbin processing device for sequentially supplying yarn supplying bobbins to a yarn winding device.

Background

Conventionally, a machine base is composed of a bobbin processing device and an automatic winder having a plurality of units. The bobbin handling device mounts a bobbin wound with yarn on a tray, performs various yarn handling processes, and finally supplies a yarn supplying bobbin to an automatic winder.

The machine table has 1 blower for operating the unit of the automatic winder and the suction mechanism of the yarn processing devices of the bobbin processing device.

In this case, even in a state where each unit of the automatic winder can be operated at a low static pressure, a high static pressure is required for the plurality of yarn processing devices of the bobbin processing device. Therefore, the blower is operated in cooperation with the bobbin processing device. Thus, power is wastefully consumed.

Conventionally, a structure in which a dedicated blower is provided in a bobbin processing apparatus is known (see, for example, patent document 1). In patent document 1, 1 suction source is provided for 1 head finding device, and energy saving is achieved by switching between low pressure and high pressure.

Next, when the empty tray 3 reaches a position directly below a yarn bobbin groove (not shown) of the yarn supplying bobbin supplying device 13, the yarn supplying bobbin 5B is placed on the empty tray 3 in a substantially upright state.

Next, the tray 3 is conveyed on the main conveyance line 121 toward the 1 st package yarn unwinding device 15A on the downstream side. In the 1 st package yarn unwinding device 15A, the removal of the lower package yarn formed on the yarn supplying bobbin 5B is performed again. This is to reliably remove the lower end yarn which cannot be removed by the end yarn remover 14.

Next, the yarn supplying bobbin 5B is conveyed toward the 1 st yarn end processing device 17A on the main conveyance line 121. In the 1 st yarn end processing device 17A, the rewinding yarn wound around the surface of the yarn layer of the yarn supplying bobbin 5B is cut to form a yarn leading end side wound portion.

Next, the yarn supplying bobbin 5B is conveyed toward the 1 st changing device 19A on the main conveyance line 121. In the 1 st piecing device 19A, the yarn leading end side winding portion is sucked upward, and the end portion of the yarn is inserted into the inside of the tubular body of the yarn supplying bobbin 5B.

Subsequently, the yarn supplying bobbin 5B is further transported downstream on the main transport line 121 and supplied to the supply path 106 of the automatic winder 102. The yarn supplying bobbin 5B is transported on the supply path 106 and supplied to one of the winding units 105.

In the winding unit 105, the yarn is unwound from the yarn supplying bobbin 5B, and the unwound yarn is wound into a package.

(7) Effects of the embodiments

As an example of each of the plurality of suction mechanisms (the 1 st suction unit and the 2 nd suction unit), a description will be given of a suction operation in a combination of the 1 st head changer 19A and the 2 nd head changer 19B.

nd head devices

19A and 19B are operated for different types of yarns, the suction operation of the 2 nd head device 19B may be stopped when the 1 st head device 19A performs the suction operation, and the suction operation of the 1 st head device 19A may be stopped when the 2 nd head device 19B performs the suction operation. That is, a state in which only one of the two is operated and a state in which only the other is operated are repeated.

In the above description, the 1 st suction mechanism 47 and the 2 nd suction mechanism 51 are used in the description of the combination example of the 1 st suction unit and the 2 nd suction unit. However, the combination example of the 1 st suction unit and the 2 nd suction unit may be any combination of a plurality of suction mechanisms including the 3 rd suction mechanism 53, the 4 th suction mechanism 57, the 5 th suction mechanism 61, and the 6 th suction mechanism 65 as other suction mechanisms.

(8) Modification example

In the above embodiment, the dedicated blower is provided for all the suction mechanisms of the bobbin processing device 103, but the suction mechanism provided with the dedicated blower may be a part.

The suction mechanism provided with a dedicated blower has a configuration in which, for example, a combination of the 1 st drawing device 19A and the 2 nd drawing device 19B, a combination of the 1 st drawing device 19A and the 1 st side yarn catching section 18A, a combination of the 1 st drawing device 19A and the package yarn remover 14, a combination of the 1 st drawing device 19A and the bobbin extracting device 11, or a combination of the other two devices is minimized.

In the above case, for example, 1 or more general-purpose blowers are connected to the suction mechanism in which no dedicated blower is provided in the bobbin processing apparatus. The general-purpose blower may be dedicated to the bobbin processing device 103 or may be used in common with the automatic winder 102.

2. Other embodiments

While one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention. In particular, the plurality of embodiments and modifications described in the present specification can be combined as desired.

The number and type of the suction mechanisms in the bobbin processing apparatus are not limited to those in the above embodiments. For example, the head finding device can also be 1. Further, although the embodiment in which the bobbin processing device 103 is disposed between the bobbin supplying device 104 and the automatic winder 102 has been described, the present invention can also be applied to a configuration in which the bobbin processing device 103 is disposed between the ring frame and the automatic winder 102.

The bobbin processing apparatus may include a suction mechanism without an opening/closing device.

In the above embodiment, the suction switching mechanism is an opening/closing device provided in each suction mechanism, but is not particularly limited. That is, the suction mechanism may be provided with no opening/closing device, and another type of suction switching mechanism may be used. The other type of suction switching mechanism may be, for example, an opening/closing device that collectively operates a plurality of suction mechanisms, or may be a configuration that switches the suction by switching the pressure generated by the blower to high pressure and low pressure.

The control unit of the bobbin processing apparatus may switch between high pressure and low pressure by using an inverter.

Each blower may be constituted by a plurality of blowers.

Industrial applicability

The present invention is widely applicable to a bobbin processing device for supplying a yarn supplying bobbin to a yarn winding device.
