Description

[Detailed Description of the Invention] The present invention relates to a nozzle holder for mounting a nozzle tip, which is used when cleaning objects to be cleaned that are transported into a cleaning chamber of a cleaning machine.

Generally, a nozzle holder, that is, a nozzle chamber, which has a fluid chamber into which high-pressure fluid is supplied is fixed in the cleaning chamber of a washing machine, and a large number of nozzle chips are attached to the nozzle chamber, which is integrally formed by welding steel plates or the like. By installing the cleaning device, objects to be cleaned that are transported into the cleaning chamber can be cleaned.

Therefore, when starting and stopping the washer, impurities contained in the high-pressure fluid supplied from the high-pressure fluid supply source to the fluid chamber in the nozzle chamber settle at the bottom of the fluid chamber in the nozzle chamber, and the nozzle This may cause clogging and reduce cleaning effectiveness. Furthermore, if impurities settle at the bottom of the fluid chamber of the nozzle chamber, since the nozzle chamber is integrally formed by welding, it takes time and effort to remove the precipitated impurities, and it is difficult to completely remove the impurities. There was a problem that it could not be removed.

The present invention was devised in consideration of the above-mentioned problems, and its purpose is to quickly and easily completely remove impurities precipitated within the fluid chamber.
The object of the present invention is to provide a nozzle holder that improves the cleaning effect, has a simple structure, and can be easily implemented. The lid is composed of a frame that is fixed to the periphery of the bottom plate and has a plurality of screw holes, and a lid that is removably attached to the frame using a tightening fixing member that is screwed into the screw holes and has a nozzle tip mounting part. The tightening hole (the part to be tightened by the tightening and fixing member), which is the part where the member is attached, is characterized by having a continuous through hole with a diameter larger than the maximum diameter of the tightening and fixing member. It is.

In the above configuration, when high-pressure fluid is supplied from the supply hole of the bottom plate into the fluid chamber formed by the bottom plate, the frame body, and the lid member, the high-pressure fluid is ejected from the nozzle tip attached to the lid member and hits the object to be cleaned. Wash.

Here, in the cleaning device to which the nozzle holder of the present invention is applied, the cleaning liquid is circulated, and as a result of continuous circulation, foreign matter in the cleaning liquid may be deposited on the bottom surface of the fluid chamber of the nozzle holder. As sediment accumulates, the nozzle tip becomes clogged with foreign matter.

To deal with this, removing the lid member from the frame releases the entire area inside the fluid chamber, including the corners, making it easy to remove the sediment that has accumulated on the bottom surface of the fluid chamber. The inner wall surface can also be completely cleaned. Further, when the lid member is removed from the frame, it can be easily cleaned from the back side of the lid member with a large number of nozzle tips still attached.

In this invention, the tightening hole of the lid member is formed with a throughhole that has a larger diameter than the maximum diameter of the tightening fixing member, so when removing the lid member from the frame, it is necessary to tighten the After loosening the fixing member by the required amount, the cover member can be removed by slightly shifting it so that the position of the tear-off hole matches the tightening fixing member. According to the present invention, the lid member can be attached and detached extremely easily in a short period of time without completely removing the tightening and fixing member each time.

Hereinafter, embodiments of the nozzle holder of the present invention will be described based on the drawings.

In FIG. 1, reference numeral 1 denotes a nozzle holder, and this nozzle holder 1 is roughly constituted by a holder 2 and rectangular lid members 3, 3 detachably attached to the holder 2. As shown in FIG.

As shown in FIGS. 2 and 3, the holder portion 2 includes a bottom plate 4, which is a plate-shaped member, and has a supply hole 4a formed at the bottom of the intermediate portion for supplying high-pressure fluid from a high-pressure fluid supply source. and a frame 5 fixed along the edge of one side of the bottom plate 4 so as to have a substantially concave cross section. That is, holder 2
is a rectangular housing with long sides in the horizontal direction, and a threaded portion is provided at the protruding end 2a on the opening side of the housing to which the nozzle tip 6, shown by the chain line in FIGS. 1 and 3, is attached. By attaching the lid members 3, 3 formed at appropriate intervals, the fluid chamber 9 is closed.
is beginning to form.

A reinforcing member 9 is attached perpendicularly to the extending direction of the upper and lower frames 5a and 5b forming this holder.

As shown in FIG. 4, the lid members 3, 3 are provided with tightening holes 10 at appropriate intervals on the periphery thereof, and have a frame shown in FIG. 2. In line with the screw holes 12, ... formed in the body 5, the third
The lid members 3, 3 are detachably tightened and fixed one after another to the frame body 5 using bolts, nuts, etc. 13 shown by chain lines in the figure.

That is, the lid members 3, 3 are removably fixed to the frame 5 forming the protruding end surface 2a of the holder portion 2.

The diameter of the screw hole 12 is set larger than the maximum diameter of the bolt, nut, etc. 13 that is a tightening and fixing member. , 3 can be easily attached and detached.

The nozzle holder of the present invention having the above-described structure is assembled as follows.

That is, the nozzle holder 1 having the fluid chamber 8 inside can be easily assembled by simply tightening and fixing the lid members 3, 3 to which a large number of nozzle chips 6, . . . are attached to the holder 2 using bolts, nuts, etc. 13. It will be assembled. During assembly, the lid members 3, 3 are provided with a through hole 11 with a diameter larger than the tightening hole 10, so that the screw hole 1 of the frame 5 is connected.
2 and the tightening hole 10 of the lid member 3, and bolts, nuts, etc. 13 are installed in a loosely fitted state at first, and then both members 5, 3 are accurately positioned and tightened and fixed. It is accurate in terms of accuracy and easy to install.

The nozzle holder 1 thus assembled is fixed at an appropriate location in the cleaning chamber of the cleaning machine, and operates as follows.

First, when the object to be cleaned is conveyed into the cleaning chamber, the cleaning machine is activated and high-pressure fluid is supplied from the fluid supply source into the fluid chamber 98 of the nozzle holder 1, and the high-pressure fluid is applied from the nozzle chips 6, . The liquid is ejected toward the object to be cleaned, and when the cleaning is completed, the washer is operated again and the supply of high-pressure fluid from the fluid supply source to the fluid chamber 8 is stopped.

In this way, the objects to be cleaned that are being conveyed one after another are cleaned, but while the high-pressure fluid is repeatedly supplied and stopped, impurities contained in the high-pressure fluid are deposited at the bottom of the fluid chamber 8. will precipitate and its impurities will be deposited. Therefore, if the bolts, nuts, etc. 13 (tightening/fixing means) are removed and the lid members 3, 3 are removed from the holder 2 at the appropriate time, the fluid chamber 8 will be released. Easily remove impurities accumulated at the bottom of the
This means that the fluid chamber 8 can be cleaned.

Further, in order to clean the nozzle tips 6, . . . attached to the lid members 3, 3, a large number of nozzle tips 6, . In this embodiment, the individual nozzle chips 6 are removably screwed onto the lid members 3, 3, so if necessary, the desired nozzle chip 6 alone can be removed from the lid members 3, 3 for inspection, repair, or replacement. etc.

Therefore, clogging of the nozzle holder of the washer, which has been a problem in the past, is prevented, and the overall cleaning effect is improved.

In addition, in the embodiment, two lid members 3,
3 are arranged in a row, but the number is not limited to two, and the nozzle holder 1 may be constructed by attaching one or more sheets of width that are easy to handle in the longitudinal direction of the holder 2.

If the holder 2 is long in the longitudinal direction and a large number of lid members are installed in series, the working efficiency will be further improved.

As described above, according to the present invention, it is possible to cleanly remove deposits (including deposits) in the box-shaped fluid chamber by simply removing the lid member, and it is also possible to clean a large number of nozzle tips at the same time. In this case, since the tightening hole has a larger diameter than the tightening fixing member, the lid member can be attached and detached extremely easily, and the structure is simpler than the conventional one. At the same time, maintenance work on the nozzle holder can be performed quickly and easily.
