Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a nozzle device in a water removal machine, and more specifically, the invention is a device that sprays air from a blower to remove cleaning liquid adhering to the surface of an object to be drained. The present invention relates to a nozzle device in a water remover for removing water.

[Conventional technology]

As is well known, the surfaces of food packs, cosmetic containers, electronic parts, etc. are cleaned with a cleaning solution such as a disinfectant when they are transported at each distribution stage or when transferred between manufacturing processes.

After cleaning, the cleaning liquid adhering to the surface is removed by a device called a water remover.

The water removing machine includes a conveyor for conveying the drained object from one side to the other side, and in the process of conveying the drained object from one side to the other side by the conveyor, A nozzle device is provided for blowing air from a blower onto the surface of the object to be drained to remove the cleaning liquid adhering to the surface. The above-mentioned nozzle device is equipped with a nozzle body for injecting air toward the object to be drained, but in conventional nozzle devices, this nozzle body is mainly arranged in the vertical direction with respect to the object to be drained. There is.

[Problem that the invention attempts to solve]

The reason why the nozzle body is arranged mainly in the vertical direction of the draining object in this way is that the thickness of the draining object conventionally tends to be relatively thin, and in this case,
This is because even cleaning liquid adhering to the side surfaces can be drained relatively well.

That is, the air blown onto the upper or lower surface of the object to be drained also flows to the side surfaces, thereby making it possible to drain the cleaning liquid adhering to the side surfaces. However, recently there has been a tendency for objects to be drained to be relatively thick, and in such cases, it is not possible to spray sufficient air to the entire sides of the object by only blowing air from above and below the object. .

Therefore, although they were originally placed above and below the object to be drained, the following technology was used to blow air from the sides. That is, the upper end of a flexible metal hose is fixed, a nozzle body is arranged at the lower end, the metal hose is extended, and the nozzle bodies are positioned on the left and right sides of the object to be drained, so that air can be sprayed onto the sides of the object to be drained. Although some of the technology has been put into practical use, this technology has the following problems.

In other words, when the width of the object to be drained changes, when the metal hose is shaken to change the approach position to the side of the nozzle body, the metal hose may become slanted or straight because the upper end is fixed. The height position changed by that amount. The air blowing position changes. That is, it is not possible to adjust the left and right widths while keeping the height position always optimal.

The present invention has been developed in view of the above-mentioned points, and its purpose is that even if the object to be drained is thick, the side surface of the object can be drained well, and even if the height changes. A water removal device in a water removal machine that can drain water well and can also drain water well in response to changes in width even if the width perpendicular to the direction of movement of the object to be drained changes. It is on offer.

[Means for solving problems]

The present invention has the following technical means to achieve the above object. That is, to explain using the reference numerals used in the attached drawings corresponding to the embodiments, a draining object whose surface has been sprayed with a cleaning liquid in the previous step is moved from one side by a conveyor means driven by a driving means. In the process of conveying the water from the conveyor means 3 to the other side, the nozzle device in the water remover blows air from the blower onto the surface to remove the cleaning liquid adhering to the surface. It has a pair of nozzle bodies 15a, 15b for blowing air 37 from the left and right side surfaces 2a, 2b of the object 2, and these nozzle bodies 15a, 15b have air jet ports 17 formed along the longitudinal direction. In addition, the pair of nozzle bodies 15a and 15b are arranged with the longitudinal direction up and down, and when one nozzle body 15a is brought close to the draining object 2, the other nozzle body 15b is also drained at the same time. One nozzle body 15 can be brought close to the object 2.
When the nozzle body 15a is moved away from the draining object 2, the other nozzle body 15b is also moved away in synchronization with the moving movement mechanism 26.

[Effect]

Since the present invention comprises the above technical means, it is possible to inject air 37 from the blower 20 onto the left and right side surfaces 2a and 2b of the draining object 2 being conveyed from one side 7 to the other side 8 by the conveyor means 3. can. Nozzle bodies 15a and 15b capable of injecting air to the left and right side surfaces 2a and 2b are arranged with their longitudinal directions facing up and down, and air jet ports 17
are formed along the longitudinal direction, so even if the height of the draining object 2 varies, the left and right side surfaces 2
Air 37 can be evenly blown above and below a and 2b.

0 and the blower motor 21 are connected via a belt 22. A main air pipe 23 is connected to the air outlet 20a of the blower 20. A plurality of branch pipes 24 are formed in the main pipe 23, and a stretchable air supply hose 25 is connected between these branch pipes 24 and the nozzle body 15. It is connected.

Next, 26 is an advancing/retracting mechanism, and conveyor means 3
A pair of left and right nozzle bodies 15a and 15b disposed on both left and right sides of the draining object 2, which is conveyed from one side 7 to the other side 8 by the draining object 2, are arranged to advance and retreat synchronously with respect to the draining object 2. It is set up,
In this embodiment, an example is shown in which the advancing/retracting mechanism 26 is configured as follows. That is, first, the rotation axis 2
7 is horizontally installed rotatably on the main body casing 5.
The horizontal direction is perpendicular to the conveyor means 3.

A right-handed threaded portion 28 is formed on one side of the center of the rotating shaft 27, and a left-handed threaded portion 29 is formed on the other side. Sliders 30 and 31 are spline-fitted to each of the right-hand threaded portion 28 and left-hand threaded portion 29, respectively, and one side end of the rotation shaft 27 protruding outward from the main body casing 5. By rotating a handle 32 fixed to the section, these sliders 30, 31 can be moved synchronously toward the center or away from each other.

A lateral movement guide rod 33 is installed horizontally in parallel with the rotation shaft 27, and the sliders 30 and 31, which are spline-fitted to the rotation shaft 27, are attached to the lateral movement guide rod 33 on the other side. Slide fit.

is sent to the nozzle bodies 15 through the blowing branch pipe 24 and the air supply hose 25, and is injected from the air jet ports 17 formed on the circumferential surface of these nozzle bodies 15. When the draining object 2 that has been sprayed with the cleaning liquid 38 in the previous step is sent from the conveying port 6 of the water remover 1 in such an operating state, the draining object 2 is transferred to the conveying surface 18 of the conveyor means 3.
It is placed on top and transported inside the water remover 1 from one side 7 to the other side 8.

Nozzle bodies 15 for injecting air 37 from the blower 20 are disposed vertically and horizontally of the draining object 2 conveyed in this way by the conveyor means 3. The object 2 is blown with air 37 from above and below and from left and right. Also, by slightly shifting the direction of the air jet ports 17 formed on the nozzle body 15 from the vertical and horizontal directions, air can also be supplied to the front and rear surfaces of the draining object 2. Can be sprayed well. That is, even when the thickness of the draining object 2 is thick, that is, even when its height is high, the air 37 can be well blown not only to the upper and lower surfaces of the draining object 2 but also to the left and right surfaces and front and rear surfaces. As a result, the cleaning liquid 38 adhering to each of these surfaces can be effectively removed.
Further, the pair of left and right nozzle bodies 15a and 15b disposed on both the left and right sides of the draining object 2 in the advancing direction are arranged with their longitudinal direction being vertical, and a plurality of air jet ports 17 are disposed along the longitudinal direction. ... is formed, even if the height of the draining object 2 changes, the air 37 can be evenly blown from the top to the bottom of the left and right side surfaces 2a, 2b of the draining object 2.

The width w of the draining object 2 may vary, but even if the width w of the draining object 2 changes as described above, the handle 32 of the advancing/retracting mechanism 26 can be rotated as shown by the arrow 39 in FIG. By doing so, the pair of left and right nozzle bodies 30, 31 can be synchronously moved toward or away from the draining object 2, as shown by arrows 40, 41 in FIG. can. Therefore, even if the width w of the object to be drained changes, the pair of left and right nozzle bodies 15
a, 15b can be easily moved close to the draining object 2, and excellent draining can be performed.

In this embodiment, the handle 3 of the advancing/retracting mechanism 26
Although an example has been shown in which the rotation shaft 27 is rotated by manually rotating the rotation shaft 27, the rotation shaft 27 may be rotated by an electric motor. In this case, if a sensor is provided to detect the width w of the draining object 2 and the electric motor is driven and controlled according to the detection signal, the pair of left and right nozzle bodies 15a and 15b can be controlled. It can be automatically moved to the optimal position. Moreover, this advancing/retracting mechanism 26 is not configured as described above;
For example, it may be constructed by combining link mechanisms.

Furthermore, the air outlet 17 formed on the circumferential surface of the nozzle body 15 may be formed in the shape of a slit along the longitudinal direction, as shown in FIG.

Further, in the above embodiment, an example was shown in which the nozzle bodies 15, 15 disposed above the draining object 2 were movable up and down, but these nozzle bodies 15, 1
