Abstract

PURPOSE:To provide a needle bed capable of removing and discharging fly and dust without stopping a knitting machine and requiring plural dust separators by setting a channel of fly and dust reservoir part occurring during knitting at a part lower than a tuyere part in the direction of sliding of knitting needle. CONSTITUTION:In a dust separator of a needle bed in a filling knitting machine, a channel 2 for a reservoir part of fly and dust occurring during knitting is set at a part lower than a tuyere part of the needle bed 1 in the direction of sliding of knitting needle in such a way that fly and dust piled in a needle channel part of the needle bed 1 can be dropped in the channel 2 by a blade plate part 4 attached to a knitting needle 3 during knitting through knitting motion of the knitting needle 3. The channel 2 for the reservoir part of fly and dust is equipped with a tray 5 for discharging fly so that fly and dust piled in the channel part 2 is readily taken out. A brush material 6 is fixed to the top of the tray 5 so as to remove fly and dust between knitting needles 3 so that fly and dust can be discharged without stopping operation of knitting machine and using plural dust separators.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a needle bed dust remover for a flat knitting machine.

[0002]

2. Description of the Related Art A flat knitting machine equipped with a dust removing device is disclosed in Japanese Utility Model Laid-Open No. 2-115591 and JP-A-63-105159.
Although the publications such as Japanese Patent Laid-Open Publication No. 2005-242242 have been proposed, air is ejected from needle bends at the ostium or knitting needles protruding from the ostium, or the fly or the knitting needles or ostium generated from the knitting yarn by suction air This method removes dust adhering to the parts. In the above method, the weight of the carriage that reciprocates in the width direction of the knitted fabric above the needle bed inevitably becomes heavy, and the knitting machine must be stopped in order to discharge the dust collected in the dust removing device. I had to do it.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised to solve the above problems, and provides a dust remover which does not need to be incorporated in a carriage and does not have to stop the knitting machine.

[0004]

DISCLOSURE OF THE INVENTION The present invention is characterized in that a groove for a fly and a dust accumulating portion generated during knitting of a knitted fabric is provided below the needle bed mouth part in the knitting needle sliding direction. Is. According to the present invention, by providing the groove of the fly and the dust collecting portion generated at the time of knitting the fabric under the knitting needle sliding direction from the needle bed mouth part, and installing the tray for the fly and the dust discharge in the groove. It is possible to achieve the purpose of dust removal without installing a complicated device. A whisker-shaped or comb-shaped protrusion was provided on the upper surface of the tray so as to make light contact with the knitting needles, so that the fly and dust between the knitting needles were easily taken out.

Further, a fly and a belt for discharging dust are installed in the groove, the belt is driven intermittently or continuously, and is removed by a rotating brush or the like outside the needle bed to remove dust. Maintenance work is easy.
In the present invention, the groove of the fly and dust collecting portion provided in the needle bed is effective when provided in the lower surface portion of the needle bed in which the blade portion for transfer is accommodated in the state where the knitting needle is pressed down. Target.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a needle bed having a fly removing function constructed according to the present invention will be described below with reference to the accompanying drawings. A fly 2 and a dust collecting groove 2 are provided below the needle bed 1 needle bed mouth in the knitting needle sliding direction, and the fly and the dust generated during knitting of the knitted fabric are dropped into the groove 2 so that the fly on the needle bed 1 The dust can be removed from the needle groove.

In the groove 2, fly and dust accumulated in the needle groove portion of the needle bed by the blade plate portion 4 provided on the knitting needle 3 during knitting of the knitted fabric are moved to the groove 2 by the knitting movement of the knitting needle 3. It was placed in a position where it could be dropped.
Further, the fly and dust discharge tray 5 is installed in the fly and dust collecting groove 2 so that the fly and dust accumulated in the groove can be easily taken out. A beard-shaped or comb-shaped brush material 6 is provided on the upper surface of the tray 5, and when the tray is taken out of the knitting machine and the groove 2 is regularly cleaned,
When the brush material 6 is brought into light contact with the knitting needle 3, the knitting needle 3 is vibrated so that the fly and dust between the knitting needles can be removed.

Further, in another embodiment for discharging the fly and dust accumulated in the groove portion 2, a belt 7 having unevenness in the groove portion is installed as shown in FIG. 3, and the belt 7 is provided with a pulley 8 The prime mover 9 is driven intermittently or continuously so that the fly and dust accumulated on the needle bed 1 can be discharged to the outside of the machine. Further, outside the needle bed 1, the rotating brush 10 is attached to the bed 7 which is being driven.
By pushing, the fly and the dust adhering to the belt 7 are automatically discharged to the dust box 11.

[0009]

As described above, according to the present invention, the fly and dust can be easily removed and discharged without requiring a complicated dust removing device and without stopping the operation of the knitting machine.
