  The present invention relates to a wire rod cleaning and drying apparatus.

  The surface of a conductor, for example, a conductor metal core wire (hereinafter referred to as a conductor) used for an insulated wire, is a metal powder peculiar to the metal generated in a wire drawing process or a rolling process, or a processing lubricant used in the process. Etc. are attached to the surface. It has been pointed out that the thickness of the insulating layer is becoming thinner due to demands for electrical characteristics, and applying insulating paint without removing the metal powder adhering to the conductor surface will lead to a decrease in insulation performance. ing.

  In addition, hoop materials such as metal strips and lead frames are pressed as needed after rolling, but the metal powder unique to the metal generated in the rolling process and pressing process, and the processing lubricant used in the same process And the like are attached to the surface, it has been pointed out that a defective plating occurs in the subsequent plating process, for example.

  An embodiment of the present invention will be described below.

The wire rod cleaning and drying device includes a cleaning unit having a cleaning tank for cleaning the wire rod processed by the machining device, and a drying unit that is disposed downstream of the cleaning unit and removes the cleaning liquid attached to the wire rod. A unit. In the cleaning unit, the filament material is immersed in a liquid tank, and an adhering substance such as processing oil adhered to the surface of the filament material is removed using an aqueous cleaning liquid. In the drying unit, the cleaning liquid adhering to the cleaning unit is removed from the surface of the filament material to obtain a dry surface.

  Usually, a certain amount of the cleaning liquid in the cleaning tank is pulled up from the cleaning unit in a state where it adheres to the surface of the filament material. At this time, if the processing oil as the deposit removed by the cleaning floats on the cleaning liquid surface of the cleaning tank, it reattaches to the surface of the filament material 4 when the filament material is pulled up. Therefore, it is necessary to prevent the processing oil from floating on the surface of the cleaning liquid at the location where the wire rod intersects with the surface of the cleaning liquid when it comes out from the cleaning liquid into the atmosphere.

  As a result of intensive studies, the inventors have removed the processing oil removed from the wire rod as the point where the wire rod enters the cleaning liquid increases, and the processing oil floating in the vicinity of the point is the wire rod. It has been found that the wire moves from the cleaning liquid level to the vicinity of the position where it exits into the atmosphere, and the linear material adheres to the linear material when leaving the cleaning liquid surface. From this finding, by separating the liquid surface between the location where the filament material crosses the cleaning liquid surface when entering the cleaning liquid and the location where the filament material intersects the cleaning liquid surface when leaving the cleaning liquid, It became clear that the flow of floating materials such as floating processing oil could be blocked, and that re-contamination of wire rods could be dramatically reduced.

  Therefore, in one embodiment of the present invention, a separation preventing body that separates the surface of the washing liquid and prevents the flow of suspended matter is provided in the washing tank of the washing unit. This separation blocking body has a cleaning liquid surface in the cleaning tank, an entrance region including a portion intersecting with the cleaning liquid surface when the filament material enters the cleaning liquid from the atmosphere, and when the linear material goes out of the cleaning liquid into the atmosphere. In addition, the floating material is separated from the advancing region including a portion intersecting with the cleaning liquid surface, and suspended matter that is removed from the surface of the wire rod and floats on the cleaning liquid surface in the entering region is prevented from flowing into the advancing region.

  With such a configuration, when the filament material is pulled up from the cleaning unit, the surface of the filament material is not recontaminated with the suspended matter, and a clean filament material can be sent to the drying unit.

  Next, an embodiment of a wire rod cleaning and drying apparatus according to the present invention will be specifically described with reference to the drawings.

1. First embodiment [washing and drying apparatus]
FIG. 1 is a side sectional view of an embodiment showing an apparatus for washing and drying a filament material according to the present invention and the entire peripheral apparatus.

  In front of the washing / drying apparatus 1, a processing apparatus 2 is installed as a processing apparatus 2 that applies a processing lubricant such as mineral oil or a water-soluble lubricating liquid to the wire rod 4 and performs press processing. Further, a winding drum 3 for winding the wire material 4 cleaned by the cleaning / drying device 1 and putting it into the next process is installed at the subsequent stage of the cleaning / drying device 1. In FIG. 1, the arrows indicate the traveling direction of the wire material 4, and are transferred from the left to the right in the drawing so as to pass through the steps of pressing, cleaning / drying, and winding.

  In FIG. 1, a cleaning / drying apparatus 1 for cleaning the filament material 4 is generally configured by a cleaning unit 10 and a drying unit 30. The wire material 4 is a metal wire, a metal wire, or a wire material such as a lead frame pressed by a processing apparatus. The adhering matter adhering to the surface of the wire rod is liquid or solid, for example, processing powder and processing lubricating liquid.

[Washing unit]
The cleaning unit 10 in the cleaning / drying apparatus 1 is provided with a cleaning tank 11 storing a cleaning liquid 16 for removing processing oil as adhering matter adhering to the surface of the wire rod 4, and provided in the cleaning tank 11 in this embodiment. A separation preventing body (cylindrical body 15) which is a characteristic part of the form, and a linear material feeding mechanism 13 for feeding the linear material 4 from the cylindrical body 15 to the drying unit 30 side installed in the subsequent stage.

  In the cleaning unit 10, an ultrasonic generator or the like may be installed to enhance the cleaning effect, and energy may be applied to the cleaning liquid in the cleaning tank 11.

  2 and 3 are a side sectional view and a top view showing the cleaning unit 10 in detail. In FIG. 2, the arrow indicates the traveling direction of the wire rod 4, and the pressed wire rod 4 is loaded from the left side in the drawing and transferred to the cleaning tank 11. In FIG. 3, the filament material 4 enters obliquely downward with respect to the cleaning liquid surface 16a, is lifted vertically upward, and is transferred to the drying unit.

(Washing tank)
The washing tank 11 washes off the processing lubricant and foreign matter adhering to the surface of the filament material 4. In this embodiment, the wire rod 4 is cleaned while being immersed in the cleaning liquid 16. A pressing roller 11 a, at least a part of which is located in the cleaning liquid 16, is disposed in the middle portion of the cleaning tank 11. By moving the wire 4 while being regulated by the pressing roller 11 a, the wire 4 passes through the cleaning liquid 16 and is cleaned. After that, the filament material 4 travels upward in the cleaning tank 11, passes through the interior of the filament material passage 15 a formed in the cylindrical body 15, and is taken out from the cleaning liquid surface to the atmosphere. The cleaning liquid stored in the cleaning tank 11 is appropriately selected according to the type of processing lubricant used during press processing and the amount of dust generated during press processing. In this embodiment, for example, alkaline electrolyzed water is used. Is used.

(Separation blocker)
The separation blocking body includes a cleaning liquid surface in the cleaning tank, an entrance region including a portion intersecting with the cleaning liquid surface when the linear material enters the cleaning liquid from the atmosphere, and a line material from the cleaning liquid to the air. The floating substance that is floating on the cleaning liquid surface in the entry area is prevented from flowing into the advance area. By separating the liquid surface between the entry area and the advance area with the separation prevention body, it is possible to block the flow of floating substances that float, and take out the linear object from the cleaning liquid surface where floating substances are not floating Can do. Therefore, when the filament material is pulled up from the cleaning unit, the surface of the filament material is not recontaminated by the suspended matter, and a clean filament material can be sent to the drying unit.

  In some embodiments, the separation preventing body has a linear material passage that is inserted at an intersecting position of the cleaning liquid surface that intersects when the linear material comes out of the cleaning tank and travels the linear material. A cylindrical body that separates the cleaning liquid surface in the cleaning material passage from the cleaning liquid surface outside the passage may be used. By simply inserting a cylindrical body having an annular passage at the intersection of the cleaning liquid level, the surface of the line material is not recontaminated with floating substances when the line material is pulled up from the cleaning unit. Strips can be sent to the drying unit.

In the embodiment shown in FIG. 2, the cylindrical body 15 has a filament material passage 15 a through which the filament material 4 passes. The cylindrical body 15 is inserted into the cleaning tank 11 so that the filament material passage 15a comes to the intersection position of the cleaning liquid surface 16a that intersects when the filament material 4 comes out of the cleaning tank 11. By this installation, the surface of the cleaning liquid 16 entering the filament material passage 15a (the advance region B) and outside the filament material passage 15a intersect the cleaning liquid when the filament material 4 enters the cleaning liquid from the atmosphere. The cleaning liquid surface (entrance region A) including the location to be separated is separated by the wall of the cylindrical body 15. The surface of the line material 4 is recontaminated to the floating material when the line material 4 is pulled up from the cleaning unit 10 simply by inserting the cylindrical body 15 having the line material passage 15a at the crossing position of the cleaning liquid surface. The clean filament material 4 can be sent to the drying unit 30. In order to further improve the cleanliness of the surface of the wire rod 4, a clean cleaning liquid may be supplied to the wire rod passage 15a.

  Moreover, as shown in FIG. 3, the cross-sectional shape of the linear material channel | path 15a of the cylindrical body 15 is substantially similar to the cross-sectional shape of the linear material 4, and is carrying out the rectangle here. The cross-sectional shape of the wire rod passage 15a surrounds the wire rod 4 via a predetermined gap, for example, a 1 mm gap, between the inner wall of the wire rod passage 15a and the wire rod 4.

  Although the cylindrical body 15 can be constituted by a simple cylinder having a linear material passage 15a, an overflow liquid reservoir 15b having a concave cross section projecting in an annular shape around the cylindrical body 15 is formed as in the illustrated example. You may do it. The cylindrical body 15 is submerged below the cleaning liquid surface 16a to such an extent that the cleaning liquid does not enter the overflow liquid reservoir 15b, and the cleaning liquid surface 16a is pushed out of the linear material passage 15a and pushed out downward. Thereby, compared with the case where the cylindrical body 15 is comprised only with a cylinder, the advancing area | region B and the approach area | region A of a washing | cleaning liquid surface are separated further, and the process oil which floats on the washing | cleaning liquid surface 16a is made into the filament material channel | path 15a. Involvement can be prevented more effectively. Further, since this overflow liquid reservoir 15b serves as a buffer for storing the cleaning liquid 16, it is effective that the cleaning liquid surface 16a rises to near the height of the cylindrical body 15 and flows into the filament material passage 15a. Can be prevented.

(Wire material feed mechanism)
The wire rod feed mechanism 13 is installed above the cylindrical body 15 installed in the cleaning tank 11. After the wire rod 4 passes through the inside of the wire rod passage 15a formed in the cylindrical body 15, it is pulled up vertically by the wire rod feed mechanism 13 installed at the upper side, and the atmosphere from the cleaning liquid surface 16a. Taken out. Between the wire rod passage 15a and the wire rod feed mechanism 13, an air blow nozzle 18 for blowing off liquid may be provided as necessary.

[Drying unit]
FIG. 4 is a side view of the drying unit 30. The drying unit 30 is provided in the subsequent stage of the cleaning unit 10. In the present embodiment, the drying unit 30 is configured to be supplied with gas by a gas supply means (not shown), and is configured to blow this gas onto the filament material 4 through the gas blow nozzle 35. In FIG. 4, the arrow indicates the traveling direction of the wire rod 4, and the wire rod 4 is transferred from the bottom to the top and from the left to the right in the drawing. The drying unit 30 performs drying by blowing a gas to the filament material 4 that has passed through the cleaning tank 11.

  The drying unit 30 may include a heating mechanism 32 that heats the gas to be blown as necessary. In the heating mechanism 32, for example, a heater hot plate (not shown) capable of adjusting the heating temperature is disposed, and the gas is heated when the gas passes through the pipe heated by the heater hot plate. The cleaning liquid evaporates by spraying the gas heated in this way onto the wire rod 4. Accordingly, the wire rod 4 that has passed through the drying unit 30 is transferred to the winding drum 3 with the cleaning liquid 16 removed.

[Action]
As described above, at the location where the wire rod 4 intersects the cleaning liquid surface 16a when coming out of the cleaning liquid 16 into the atmosphere, it is necessary to prevent the processing oil from floating on the cleaning liquid surface 16a. In the present embodiment, the filament material passage 15 a is disposed at a position where the cleaning liquid surface 16 a and the filament material 4 intersect when the filament material 4 exits the cleaning tank 11. For this reason, the cleaning liquid surface 16a between the portion intersecting with the cleaning liquid surface 16a when the linear member 4 enters the cleaning liquid 16 and the portion intersecting with the cleaning liquid surface 16a when the linear member 4 exits the cleaning liquid 16 is formed. To separate. Thereby, it becomes possible to block | distribute the flow of the processing oil which floats, and re-contamination of the filament 4 can be reduced dramatically.

Moreover, the cleanliness of the surface of the filament material 4 can be improved by supplying a clean cleaning liquid to the filament material passage 15a.

  Further, the flow rate of the clean cleaning liquid supplied to the wire rod passage 15a is more than twice the amount of the cleaning liquid brought out by the wire rod 4 when the clean cleaning liquid is not supplied. Cleanliness can be improved. The reason is as follows.

  In FIG. 1 and FIG. 3, the cleaning liquid 16 adheres to the surface of the wire rod 4 pulled up from the cleaning tank 11 in the form of a liquid film. The thickness of the adhering cleaning liquid film depends on the pulling speed of the filament material 4, but is approximately 10 to 70 μm when the hydrophilic material is pulled vertically upward from the water. As an example, considering the flow rate of the cleaning liquid attached to the lead frame traveling at a width of 4 cm and a linear velocity of 4 m / min, considering that the surface area is reduced by punching, 3 to 20 mL / Min. Therefore, when the predetermined gap of the wire rod passage 15a is about 1 mm, the clean wire is supplied to the wire rod passage 15a only by supplying a clean cleaning liquid at least twice this flow rate (6 to 40 mL / min or more). The cleanliness of the surface of the material 4 is greatly improved (see Examples 2 and 3).

[Effect of the embodiment]

(2) Also, when drying a liquid having a large latent heat of evaporation such as water, the energy to be input can be reduced, and the reduction of energy cost and the reduction of CO ₂ emission through the reduction of energy consumption can be realized.

(3) Furthermore, it is not necessary to perform cleaning using an organic solvent by performing drying after cleaning the filament 4 with the aqueous cleaning liquid 16 using the cleaning / drying apparatus 1 according to the present embodiment. As a result, leakage of the organic solvent to the atmosphere can be reduced, and the occurrence of VOC can be suppressed, the work environment can be improved, and the influence on the air environment can be reduced.

And a wire rod feed mechanism 13 for feeding out the wire. Further, when the wire rod 4 is drawn from the liquid surface to the atmosphere, the cylindrical body 15 having the wire rod passage 15a for separating the liquid surface at the position where the wire rod 4 intersects the liquid surface can be installed. It has become. In the present embodiment, alkaline electrolytic water is used as the cleaning liquid stored in the cleaning tank 11.

And a wire rod feed mechanism 23. Moreover, when the filament material 4 is pulled out from the liquid surface to the atmosphere, the cylindrical body 25 having the filament material passage 25a that separates the liquid surface at the position where the filament material 4 intersects the liquid surface can be installed. It has become. The cleaning liquid stored in the cleaning tank 21 is appropriately selected according to the cleaning liquid stored in the cleaning tank 11, the final target cleanliness, and the like. In this embodiment, pure water is used.

In Examples 1 to 3, a cylindrical body having a wire rod passage is installed. The wire rod passage 15a surrounds the wire rod through the wire rod 4 and a gap of about 1 mm. In Comparative Example 1, the cylindrical body was not installed. In both the examples and comparative examples, the lead frames used for evaluation had a width of 40 mm and a thickness of about 0.2 mm, and were run at a linear velocity of 4 m / min. The wire rod 4 was wound into an appropriate length after being wound up, extracted with a solvent, and the amount of oil (residual oil concentration) adhering to the surface was compared and evaluated. This is a comparative evaluation of the cleaning performance when the cleaning liquid is supplied to the filament material passage 15a and when it is not supplied.
