Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses a water fountain to remove carbon-based dirt (generally referred to as smut) that is still attached to the surface of a steel object and that is applied to a washing machine for an object to be cleaned. Regarding the cleaning machine that removes.

As is well known, the above-mentioned objects to be cleaned have carbides attached to their surfaces, which are commonly referred to as "black stains," so they are generally immersed in an acidic solution (e.g., hydrochloric acid, sulfuric acid) as a pickling treatment. We are trying to eliminate "kawa". However, with "Kurokawa", the iron content changes to iron hydroxide and dissolves in the solution due to the combination with the acidic solution, but the carbon content (smut) remains on the surface of the object to be cleaned without being able to be treated. It ends up. Despite this fact, until now, there has been no suitable cleaning technology that can efficiently and cleanly remove this smut, and the advent of one has been awaited.

The present invention was devised in response to the above-mentioned desire, and includes a plurality of water fountain pipes located outside the object to be cleaned in a cleaning tank, which are rotatably set, and a water fountain from the nozzle of each pipe. The water fountain is designed to spray water while changing its direction over an appropriate cleaning angle range on the outer surface of the object to be cleaned, and its purpose is to spray water around the entire circumference of the object to be cleaned, especially cylindrical and coiled materials. The objective is to cleanly remove smuts and efficiently clean the objects to be cleaned.

An embodiment of the present invention will be described below with reference to the drawings. In this example, an example of a cleaning method is shown in which a coiled material (also simply referred to as a coil body), which is made by bundling iron wire into a roughly wound shape, is used as an object to be cleaned. Reference numeral 1 denotes a cubic washing tank, and a door 2 is installed on the top surface of the tank so that it can be opened and closed. This door 2 is
As shown in Figures 1 and 2, the opening/closing mechanism is supported horizontally by rails 3 on both sides installed between the tank 1 and the machine F, and both rear ends are installed in the machine F, i.e., a reversible motor that is activated and operated as appropriate. 4 is connected via a connecting plate 7 to chains 6 on both sides which are reciprocated via an operating chain 5. This opening/closing mechanism includes a detection switch 8 for the open and closed end positions of the door 2,
9 is attached. The switches 8 and 9 are arranged at the upper right end of the tank 1 and the upper left end of the fuselage F,
When it comes into contact with the front and rear ends of the door 2, each is activated (ON) to detect the position and stop the motor 4. Furthermore, door 2
An escape port 10 for a supporting arm 13, which will be described later, is formed at the center of the front end. 11 is a water tray installed on the upper surface of the fuselage F, which receives water adhering to the door 2 and returns it to the tank 1.

Reference numeral 12 denotes a support for loading and unloading coil bodies, and a substantially L-shaped support arm 13 on the lower surface supports a plurality of coil bodies C.
are arranged and supported in a hanging manner. The support body 12 can be moved up and down, left and right, and front and back as necessary by appropriate means, and is mounted horizontally between pedestals 14 installed at the center of the left and right ends of the top surface of the tank. Ru. A confirmation detector 15 is attached to one side of the pedestal 14 (on the right side in the figure). As shown in FIG. 4, this detector 15 is used to check whether the mounting state of the support body 12 is good or not, in other words, whether the coil body C is set to be carried in or not. a lift detection rod 16 which can be brought into contact with one end of the support body 12;
and a switch 17 operated by the same rod 16, and the detection rod 1 is activated only when the support 12 is properly mounted.
When the switch 6 is lowered, the switch 17 is activated (ON), confirming this, and enabling the motor 4 of the opening/closing mechanism to start.

Inner fountain pipe 1 having a fountain device 36 in the fuselage F
8 is equipped. This pipe 18 is fitted into a fixed water pipe 19 installed horizontally at the center of the fuselage F via a sealing member 20 as shown in FIGS. , the trochanters 24 and 25 on each side of the guide holder 23 connected to the rear end while being inserted and clamped between the guide wheels 22 on the right side of the fuselage F.
is moved by a reciprocating mechanism using the mouth 27 of the tank 1 along the fixed water pipe 19 under a steady state in which it is in contact with a rail 26 installed at the center of the machine body. Note that a small diameter portion 28 and a flange 29, which constitute a part of a fountain device 36 to be described later, are formed at the mouth end 18a of the inner fountain pipe 18.

In the reciprocating mechanism, a chain 32 that is reciprocated via an operating chain 31 from a reversible motor 30 that is activated as appropriate is constructed along a rail 26, and the guide holder 23 is connected to one end of the chain 32. They are connected via 33. The motor 30 can be activated when the closing detection switch 9 is activated (when the door 2 is closed). This mechanism is provided with detection switches 34 and 35 for the front and rear end positions of the inner water fountain pipe 18. The switches 34 and 35 are arranged at the left and right ends of the rail 26, and are activated (ON) when they come into contact with the guide holder 23 to detect the position and stop the motor 30.
Incidentally, the inner water fountain pipe 18 is stationary at the retreating end before operation, and is slowly inserted forward into the center between the coil bodies C during cleaning.

The fountain device 36 at the mouth end of the inner fountain pipe 18 is in the form of a radial fountain. That is, as shown in FIGS. 5 and 7, a water flow guide 37 is fixed inside the mouth end 18a, and a movable pressure regulating plate 40 having a substantially conical guide portion 41 is attached to the outer end of the support shaft 39 of this guide 38. A bench lily channel 42 is fitted between the small diameter portion 28 and the guide portion 41, and a vent lily passage 42 is formed between the small diameter portion 28 and the guide portion 41, and the flange 29
A circular water fountain 43 is formed between the movable pressure regulating plate 40 and the movable pressure regulating plate 40, respectively. In this device 36, each blade 3 of the water flow guide 37 is designed to provide an efficient water fountain.
8 is similarly curved in the circumferential direction and axial direction of the tube 18, respectively, to form a uniform spiral shape, so that water flows out in a vortex shape. Further, the pressure regulating plate 40 is always pressed and held toward the flange 29 by a spring 46 whose pressure is regulated by an adjusting nut 45 on the threaded portion 44 of the support shaft 39.
When excessive water pressure is applied to the spring 46, the disk 40 moves outward as the spring 46 compresses and deforms, widening the water fountain 43, adjusting the water pressure from the mouth 43 as low as possible, and reducing the amount of water ( The aim is to increase the flow rate (flow rate).

A plurality of external water fountain pipes 47 are installed horizontally within the cleaning tank 1. These tubes 47 are located at 90 degrees to each other and are rotatably supported by bearings 48 outside the tank 1, and both have a large number of nozzles 49 on the same line in the axial direction on the peripheral surface facing the coil body C. They are placed at appropriate intervals. The upper and lower pipes 47 are paired, and the connecting pipes 51 at the upper and lower ends of the vertical water pipe 50
However, as shown in FIGS. 9 and 10, the pipes 47 are communicated with each other through communication ports 52 that are open in the rotation range of each pipe 47. Note that both vertical water pipes 50 are communicated with each other through a horizontal water pipe 53.

For each pair of the outer water fountain pipes 47, a direction changing mechanism for changing the direction of the water fountain from the nozzle 49 is arranged in series. In this mechanism, as shown in FIGS. 3 and 8, a vertical ring 55 is articulated between arms 54 connected to the outer ends of the shafts of each tube 47 to form a four-section parallel configuration, and a vertical link 5
5 and a rotary disk 58 coaxially connected to a worm wheel 57 of a reduction gear 56, a crank rod 59 is articulated to the rotary disk 58. The driving means for both mechanisms is a single motor 60 that is driven in synchronization with the motor 30, and its main shaft 61 is connected to a rotating shaft 6 supported by the tank 1.
2 are connected, and each worm 63 of the same shaft 62 is meshed with each wheel 57. As a result, in response to the drive of the motor 60, the rotation of the rotary disk 58 of the wheel 57 on each side and the vertical movement of the vertical link 55 causes the tubes 47 to reciprocate at a very slow speed in synchronization, changing the direction of the nozzle 49. By the way, the direction range of the nozzle of each tube is, for example, about 70 degrees between points A and B in the diagram (however, the effective fountain area is 90 degrees or more with respect to the outer circumference of the coil body), and the fountain direction of each tube is The nozzles 49 are moved from this point in the same direction as shown by the arrows so as not to interfere with each other. In addition, in each direction change mechanism, each member 54, 55, 58, 59 comrades,
For example, the tubes may be connected using elongated holes or the like so that the amount of direction change and rotation of each tube can be adjusted.

Connections and drainage systems for the cleaning tank 1 and the fountain pipes 18 and 47 are additionally described based on FIG. 11. Tank 1
The upper and lower limits of the liquid level are set for
Water _W1 overflowing from another washing tank is poured into the tank. Then, water W ₂ in the tank is pumped up from a position below the lower limit by the water supply pump 64, and is transferred from the fixed water pipe 19 to the inner fountain pipe 18 via the water supply pipe 65, and from the horizontal water pipe 5.
3 to each outer fountain pipe 47 via a vertical water pipe 50. Note that the pump 64 is connected to the motor 30
Suppose that it is driven in synchronization with. On the other hand, regarding drainage, when the water in the tank 1 rises above the upper limit, the drain pump 69 is driven by the operation (ON) of the switch 68 in response to the upward movement change of the float 67 in the level detector 66. The pumped water _W3 is discharged to the outside of the tank via the drain pipe 70. It is assumed that the motors 4, 30, 60 and the pumps 64, 69 are sequentially operated based on a program (cycle) set by one control device.

In this cleaning machine, the coil body carried into the cleaning tank 1 is cleaned by the cooperative fountain operation of the inner and outer water fountain pipes 18 and 47. That is, when the pickled coil body C is carried in by the support 12 with the door 2 open and the support 12 is set between the cradle 14, based on the detection operation of the confirmation detector 15. The motor 4 of the opening/closing mechanism is activated as appropriate, and the door 2 moves forward as the chain 6 moves forward. When the closing detection switch 9 is activated when the door 2 is closed, the motor 4 is stopped, and the motor 30 of the reciprocating mechanism, the motor 60 of the direction change mechanism, and the water supply pump 64 are activated as appropriate. The movement of the inner water fountain pipe, the direction change and rotation of the outer water fountain pipe 47, and the movement of the inner and outer water pipes 1
The fountain operation from 8 and 47 is carried out in parallel.

First, in the inner fountain pipe 18, the pump 64 causes water to flow from the fixed water pipe 19 into the fountain device 36,
Then, during a suitable number of front and rear movement processes as the chain 32 reciprocates, water is sprayed from the mouth 43 of the device 36 to clean the inner circumferential surface of the coil body. This device 3
6, a large amount of water at low pressure (e.g. 3-5Kg/cm ² ,
2,000 to 3,000/min) is ejected in a radial curtain shape, and the kinetic energy removes the smuts by blowing them away. Therefore, there are problems with other technologies that spray water from multiple small-diameter nozzles, i.e., the water from the nozzles is under high pressure and in small amounts (e.g. 40-70 kg/cm ² , 30-1000 kg/cm 2 ).
/min) and is ejected in the form of a mist, which unnecessarily cools the surface of the coil body, which causes the smut to stick and makes it difficult to remove. It can be efficiently washed in a matter of time (about 1 minute).

On the other hand, in each of the outer fountain pipes 47, the pump 64
When the water is uniformly inflowed through the horizontal and vertical water pipes 53 and 50, and the nozzle 49 is directed to the same position of either point A or B, both direction changing mechanisms are synchronized. Each nozzle 49 is rotated back and forth an appropriate number of times during operation, and in the process of steplessly changing the direction of the fountain.
Fountains all at once. As a result, more than 1/4 of the outer periphery of the coil body is washed for each tube 47, and the entire periphery is evenly washed with water due to the action of the changing direction of the water jet, and the smut is thoroughly removed. In particular, in each tube 47, the fountains are rotated clockwise, for example, and counterclockwise, so that the directions of the fountains do not oppose each other, so that the fountains do not interfere with each other and the flow force does not decrease. You can cleanse your body efficiently.

At the end of cleaning, each motor 30, 60 is stopped, and the inner water fountain pipe 18 is returned to the rear end, and each outer water fountain pipe 47 is returned to point A or B, respectively, and the water supply is stopped. After that, the door 2 is opened by starting the motor 4.
is opened, and the washed coil body C is carried out by the upward movement of the support body 12.

In particular, in this example, by operating the direction change mechanism for each pair of outer water fountain pipes 47 with a single drive unit, all the pipes can change direction and rotate at a synchronous speed in an equal cleaning area with respect to the coil body. Therefore, the cleaning ability of each tube is uniform, and uneven cleaning of the coil body can be avoided and cleaning can be carried out efficiently.

Note that the number of external water fountain pipes 47 corresponds to the external shape of the object to be cleaned (for example, 3 in case of a small diameter cylindrical body).
(A book is also possible.) Further, the direction changing mechanism may be of a type in which a chain is hung from a chain wheel provided on each pipe 47, or a type in which a rack is meshed with a pinion. Of course, each tube may be made independently rotatable. Inner fountain pipe 18 and outer fountain pipe 47
The operation and water supply may be made separate from each other. Accordingly, in consideration of the shape of the object to be cleaned, for example, it becomes possible to suspend the inner water fountain pipe 18 and wash only with the outer water fountain pipe 47.

As described above, the cleaning machine of the present invention includes a support body that supports a plurality of coiled materials in a suspended arrangement and is installed in such a way that it can be moved in and out of the cleaning tank, and a support body that supports a plurality of coiled materials arranged in a suspended manner so that the support body can be moved in and out of the cleaning tank. a detector for checking the set state; a door disposed on the top surface of the cleaning tank that is closed by an opening/closing mechanism operated based on detection by the detector; It is mainly composed of a plurality of outer jet pipes which are arranged facing each other on the outside of the coil member and have a nozzle on the outer periphery, and an inner water jet pipe which is arranged opposite to each other inside the coiled material and has a water fountain part almost at the tip thereof, Each of the outer water fountain pipes is configured to be rotatable over a required angle in the inner circumferential direction so that the direction of the water fountain from the nozzle can be changed relative to the coiled material, and the inner water fountain pipe is rotated through a reciprocating mechanism. It is set to allow entry and exit into the cleaning tank when the door is closed, and the fountain part of the inner fountain pipe is equipped with a water flow guide having spiral blades that spout water in a spiral shape, and a water flow guide with a low fountain pressure. Equipped with a movable pressure control panel that can automatically adjust the flow rate to a large amount, the pickled coiled materials can be supported in rows on supports and automatically transported into the cleaning tank via the supports. In addition, after the support is carried into the specified position in the cleaning tank, the opening/closing mechanism is activated via the detector to close the door of the cleaning tank, ensuring that the cleaning water is not easily scattered from inside the cleaning tank. is prevented. In addition, in the cleaning tank, after the door is closed, cleaning water is jetted out from the outer water fountain pipe installed on the outside of the coiled material and the inner water fountain pipe located on the inside, and the coiled material after the pickling treatment is sprayed. Smuts adhering to the surface are removed and cleaned with high efficiency. or,
The outer water fountain pipe rotates over the required angle and sprays water while changing the direction of the nozzle, so water can be effectively sprayed onto the outer surface of the coiled material. Even if it is a small-area fountain type, it can effectively spray over a wide area for coiled materials, increasing the cleaning effect, making it possible to reduce the diameter of each fountain pipe, downsize each nozzle, and reduce the number of nozzles. This makes it possible to suppress the overall size.

In addition, the inner water fountain pipe reciprocates inside the coiled material by a reciprocating mechanism, and can wash the entire inside of the coiled material. Moreover, the cleaning water spouted from the inner water fountain pipe is made of spiral blades. The smuts on the surface of the coiled material can be effectively blown away and efficiently removed by the kinetic energy of the cleaning water that is jetted out in a spiral shape by a water flow guide having a radial film. In addition, by being equipped with a movable pressure control panel, the jetting pressure of the cleaning tank spouted from the fountain part of the inner fountain pipe is low, and the flow rate is automatically adjusted to a large amount, making it possible to remove smut more efficiently. can. In other words, in the past, a small amount of cleaning water was sprayed in the form of a mist at high pressure from the inner water fountain pipe, which caused the cleaning water to unnecessarily cool the surface of the coiled material, causing the smut on the surface to adhere and be removed. What used to be difficult to remove can be effectively removed using a large amount of water flow and low-pressure cleaning water.

As described above, by using the outer water fountain pipe and the inner water fountain pipe, it is possible to remove the smut from the coiled material evenly and with high efficiency, and the entire cleaning machine can be automated to perform cleaning efficiently.
