As shown in FIG. 4, the gas sprayed from the discharge nozzle 1 onto the product and guided to the inside of the suction nozzle 2 through the suction port 20 passes between these two rollers 4 and 4 and flows into the suction passage 23. Suctioned into the end opening 24.

The suction nozzle 2 is fixed to the apparatus main body (not shown) together with the discharge nozzle 1. FIG.
As shown in, the discharge nozzle 1 is located behind the suction nozzle 2 with respect to the product A being transferred,
0 is fixed such that 0 has an appropriate angle toward the front (toward the left in FIG. 1) (this angle is most suitable depending on the conditions such as product size, transfer speed, wind speed, etc.). You can select and implement this).

In order to efficiently receive the gas such as the air blown out from the blow-out port 10, the suction nozzle 2 is also at a slight angle, that is, the suction port 20 does not face directly below, but the lower rear part of the product. (Toward the rear is the right direction in FIG. 1) toward the front of the vehicle. In particular, as shown in FIG.
As shown in, a tap 26 is set up on the side portion of the box portion 200 of the suction nozzle 2 so as to be concentric with the above-described outlet pipe 25 provided on the opposite side portion.
The tap 26 has a threaded outer periphery, and is fixed to the apparatus main body by screwing or nut tightening (not shown). By fixing in this way, the orientation of the suction nozzle 2 can be easily adjusted. At the time of adjustment, the screwing or the nut may be loosened, the direction of the suction nozzle 2 may be changed to a desired angle, and then the screwing or the nut may be tightened again (not shown).

The transfer means 3 is a device such as a conveyor that can place a product on the upper surface and convey it to another. Such transfer means 3 can move the product relative to the discharge nozzle 1 and the suction nozzle 2 and sequentially change the corresponding parts.

Of course, the discharge nozzle 1 and the suction nozzle 2 may be moved with respect to the product. However, by using a device such as a conveyor, the product is discharged toward the discharge nozzle 1 and the suction nozzle as in the above embodiment. By moving the nozzle 2 with respect to the nozzle 2, it is easy and convenient to install the deposit removing device of the present invention in the product manufacturing line.

In the embodiment shown in FIG. 1, the discharge nozzle 1 and the suction nozzle 2 are arranged only above the transfer means 3, but the mounting surface of the transfer means 3 (in the case of a belt conveyor, It is also possible to dispose the discharge nozzle 1 and the suction nozzle 2 below the transfer means 3 by making the belt) a breathable one such as a wire mesh (not shown).

The apparatus of the present application configured as described above is shown in FIG.
It is optimal to use one of the rollers 4 in contact with each other as shown in FIG. In this state, the sucked gas can be sucked efficiently without being dispersed. Discharge nozzle 1
The optimum blowing air velocity is about 80 to 150 m / s (per second). At this time, the transfer speed of the transfer means 3 is about 2-1.
5 m / s is suitable.

On the other hand, it is not always necessary to bring the roller 4 into contact with the product while adopting the above structure.
For example, good suction can be performed even in the state shown in FIGS. 11 and 12, that is, in the state where no contact is made. Further, as a premise of the suction efficiency as described above, the product A is moved by the transfer means 3 from the state shown in FIG. 11 to the state shown in FIG. 12, but by disposing the suction nozzle 2, as shown in FIG. , The occurrence of Karman vortices has been completely eliminated.

As described above, by forming the two rollers 4 and 4 in front of and behind the suction port 20 of the suction nozzle 2, the direction of the suction nozzle 2 can be changed even when the transfer direction is reversed. It is convenient because adjustment is possible and the arrangement position of the discharge nozzle 1 is changed.

Further, if there is no room for selection or change as described above, the roller 4 located behind the suction port 20.
Can be implemented with a simple pipe that does not rotate. In the above case, as shown in FIG. 13, it is also possible to implement it as if only one roller 4 located in front of the suction port 20 was provided from the beginning. However, in order to obtain the effects of the present invention to the maximum extent, the above-described configuration in which the rollers 4 and 4 are provided on both front and rear sides is most suitable.

Further, as shown in FIG. 14, an opening is formed at the center of the bottom surface of the housing part 210, one roller 4 is arranged at the center, and the gap between the front and rear of the roller 4 is sucked into the suction port 20, It is also possible to implement as 20.

Even when the suction nozzle 2 (the roller 4 of the suction nozzle 2) is used without being brought into contact with the product, the following effects can be obtained if the two rollers 4 and 4 are provided in front and rear. . As shown in FIG. 17, when the suction nozzle is not provided with the roller 4, for example, the nozzle 2 '
In the case of a box body having a substantially rectangular cross-sectional view, with respect to the air that has been sucked and has come to the front and rear end portions (whether or not it has been discharged by the discharge nozzle 1), The airflows e, e not directed to the suction port 20 are generated. However, by providing the rollers 4 and 4 as described above, such air flows e can be directed toward the suction port 20 as shown in FIG. Therefore, providing the rollers 4 and 4 at the front and rear is
It is extremely preferable even when it is not premised on contact with the product.

When the product is a wire rod S such as a strand, as shown in FIG. 15, the roller 4 (of the roll 40) is used.
An appropriate number of grooves 43 are formed on the surface along the circumferential direction r, and the wire S is guided in the grooves 43.
When the wire S is to be processed in this way, a transfer means other than the conveyor, that is, a device such as a winding tool that pulls the wire is used as the transfer means.

[0047]

As a result of the implementation of the first invention of the present application, the generation of Karman vortices can be suppressed and the deposits on the product surface can be reliably removed. At that time, the efficiency with which the suction nozzle collects the deposited matter that has been blown off is significantly improved. In particular, when the gas is discharged or sucked, it is possible to easily carry out the airtight chamber in an open state instead of separately forming it. As a result, it can be easily incorporated into a production line or the like, and the above effects can be obtained at an extremely low cost. Further, as described above, the discharge and suction of gas is not performed inside an airtight room but is performed in an open state, so that whatever product is going to be processed, It is extremely versatile in that it can be relatively easily handled with slight adjustments and can easily remove deposits.

By carrying out the second invention of the present application, the above first
In addition to obtaining the same effect as the invention of, the most effective roller arrangement has been made from the beginning,
It is possible to easily enjoy the first effect to the maximum without requiring large-scale adjustment.

By carrying out the third invention of the present application, in addition to obtaining the effects of the first or second invention of the present application, the fine adjustment of the wind pressure, the wind speed or the air volume when the suction nozzle sucks is performed by the suction. It is possible by adjusting the nozzle side.

By carrying out the fourth invention of the present application, in addition to obtaining the effects of the first, second, or third invention of the present application, the surface of a product having a long special shape such as a strand wire is also provided. The deposits can be removed extremely smoothly.
