In order to achieve the above object, the present invention provides an embroidery machine having a plurality of heads 12 on a main body 10, which is connected to a plurality of branch pipes 21 having respective suction heads 22. A main duct 20 installed on the main body 10; An auxiliary duct 30 installed on the main body 10 in a state of being connected with a corrugated pipe 31 having each suction head 32; An exhaust duct 41 installed together with the pump 42 to intake through the main duct 20 and the auxiliary duct 30; A valve 40 installed to selectively communicate the main duct 20 and the auxiliary duct 30 with the exhaust duct 41; And an operation panel 50 additionally provided with a function of controlling the operation of the pump 42.

As another feature of the invention, the branch pipe 21 is formed of a deformable flexible material and mounted to be accessible on the main body 10.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

Figure 1 is a front view of the embroidery machine showing the installation state of the device according to the invention, Figure 2 is a schematic view showing a cutaway portion A-A of FIG.

According to the present invention, the main duct 20, the auxiliary duct 30, and the exhaust duct 41 are installed on an embroidery machine having a plurality of heads 12 on the main body 10, and the valve 40 and the pump 42 are installed. It relates to a device for discharging polluted air by using.

The main duct 20 is installed on the main body 10 in a state of being connected to a plurality of branch pipes 21 having respective suction heads 22. Since the head 12 is disposed at regular intervals on the front surface of the main body 10 and the space is narrow, the main duct 20 is preferably configured to be embedded rather than exposed to the main body 10. Branch pipe 21 is connected to the main duct 20 via the T-shaped joint pipe 23 and disposed so as to be between each head 12. The suction head 22 is shaped into a hemisphere and placed towards the table 11.

At this time, the branch pipe 21 of the present invention is formed of a deformable flexible material and is mounted to be accessible on the main body 10. Since the branch pipe 21 and the suction head 22 suck dust on the table 11 and are always fixed at a constant position, dust may accumulate in a portion where the vacuum suction force is weak on the table 11. This is to change the position of the head 22 little by little.

The auxiliary duct 30 is installed on the main body 10 in a state of being connected with the corrugated pipe 31 having the respective suction heads 32. Auxiliary duct 30 is not often used, so use 1-2 if necessary. Corrugated pipe 31 is a structure that can be stretched can be pushed in or out of the housing (33). The suction head 32 is shaped in the hemispherical shape as described above.

At this time, when the corrugated pipe 31 needs to be drawn out in a relatively long length, a general hose may be used instead of the corrugated pipe 31 and a separate winding mechanism may be installed in the housing 33. Accordingly, when the corrugated pipe 31 and the suction head 32 reaches the entire portion of the embroidery machine, it is possible to maintain the overall clean state.

The exhaust duct 41 is installed together with the pump 42 to intake through the main duct 20 and the auxiliary duct 30. The exhaust duct 41 is for discharging the sucked polluted air to the outside is installed in an appropriate length according to the site conditions. If the length of the exhaust duct 41 is too long, the capacity of the pump 42 may be insufficient, so it is preferable to connect it to a dust collector provided separately. The dust collector is equipped with a filter so that clean air is discharged to the outside and only dust is filtered out.

The valve 40 is installed to selectively communicate the main duct 20 and the auxiliary duct 30 with the exhaust duct 41. The valve 40 for the selective connection of the main duct 20 and the auxiliary duct 30 is preferably a three-way valve. In the case of the manual valve 40, the valve 40 is exposed to facilitate the operation of the lever, and in the case of the solenoid valve 40, the valve 40 is concealed and connected to the operation panel 50 to be described later.

The operation panel 50 according to the present invention further has a function of controlling the operation of the pump 42. The operation panel 50 includes a switch 51 for selecting an operation and a relay for applying power to the pump 42. The switch 51 uses a toggle type in which an on-off position is held. However, when the on / off of the pump 42 is controlled using the microcomputer circuit and program of the operation panel 50, it is also possible to use the touch type switch 51 or to configure the switch 51 for emergency stop.

3 shows an overall schematic piping diagram for illustrating the operation according to the invention.

In operation, when the switch 42 is turned on and the pump 42 is operated at the same time as the start of the embroidery machine, the dust of the table 11 is removed from the suction head 22, the branch pipe 21, the main duct 20, and the valve ( 40) is discharged through the exhaust duct 41. At this time, the valve 40 is in the same position as shown in FIG. 3, and after switching is completed, the main duct 20 is blocked and the auxiliary duct 30 communicates with the pump 42 after the embroidery is finished. The valve 40 in the illustration shows a 2 position 3 way format.

Thereafter, the worker pulls out the corrugated pipe 31 from the housing 33 and sucks dust from another part of the embroidery machine using the suction head 32. When the work is completed, the switch 51 of the operation panel 50 is changed to the off position to stop the pump 42.

On the other hand, in the case of controlling the pump 42 using the operation panel 50, the valve 40 also adopts a solenoid method, and embroidery is started, and at the same time, the position of the valve 40 is changed to the right part of FIG. 42) and the position of the valve 40 is changed to the left part of FIG. In the latter mode, the pump 42 is operated for a certain time during which the operator can clean the necessary portion using the corrugated pipe 31 and the suction head 32.

If an error such as thread break occurs during embroidery and the embroidery machine stops temporarily, the operation panel 50 that detects this temporarily turns off the pump 42 and restarts the pump 42 at the same time as the embroidery machine is restarted.

Of course, in the case of using the microcomputer circuit of the operation panel 50 as described above, it is preferable to use the switch 51 to manually operate the pump 42 or to stop in an emergency.

According to the above configuration and action, the present invention has the effect of preventing the deterioration of durability due to the wear of the device by removing the fine dust generated during the embroidery at high speed by using the multi-head and keeps the working environment of the worker in a clean state.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
