The present invention relates to a surface treatment device for loop-shaped wires, which carries out processes such as pickling, neutralization, degreasing, and water washing while horizontally conveying the loop-shaped wire horizontally. For example, when automatically or semi-automatically welded steel wire is manufactured, it is generally manufactured through processes such as primary wire drawing, annealing, plating, finishing wire drawing, and winding. Particularly in the plating process (including plating pre-treatment and post-treatment), as a method to improve work efficiency, wire rods are placed horizontally on a conveyor in a non-concentric polymerization loop to continuously A well-known method is to perform surface treatments such as pickling, neutralization, degreasing, water washing, and plating while being transported. FIGS. 1 and 2 show specific examples of conventional surface treatment apparatuses, with FIG. 1 using a horizontal level overflow method and FIG. 2 using an immersion method. In FIG. 1a and its plan view b, a liquid supply pipe 8 incorporating a valve 9 for regulating the supply amount of processing liquid is connected to the lower side of the rectangular overflow type liquid dispersion box 1. The processing liquid 2 supplied from the liquid supply pipe 8 to the liquid spray box 1 is prevented from undulating by the rectifying plate 5.
The liquid overflows from the weir 6, hits the loop-shaped steel wire 3 conveyed by the chain conveyor 4 below, and flows down into the liquid receiving tank 7. In this processing device, the width of the liquid film 2' due to overflow is about 1 cm, and the wire passes through this liquid film 2' twice, so the contact time between the wire and the processing liquid is, for example, 3.0 cm. m/min~6.0m/
If the time is 0.2 to 0.1 seconds, the processing reaction tends to be insufficient. For this reason,
In practice, a method is adopted in which two to four devices as shown in FIG. 1 are installed in succession, which has the disadvantage of making the process extremely long. In addition, even if several devices are installed in succession, the loop-shaped wire has dense overlapping parts on the left and right sides in the direction of travel, so the processing liquid does not penetrate sufficiently into those parts, and the processing reaction is delayed. Does not progress or is delayed
Processing tends to be insufficient compared to other parts.
As a result, there was a problem that uniform surface treatment could not be performed. In the immersion method shown in Fig. 2, 10 is the processing liquid 11.
The wire rod 3 is continuously transported in the processing tank by a chain conveyor 13. Since this processing apparatus uses a dipping method, it is necessary to transport the looped wire rod by moving it up and down as shown in the figure, which causes the following disadvantages. 1 Compared to horizontal conveyance, the length of the tank is approximately twice as long, making the process extremely long. 2. When several types of treatments are performed in succession, the time required for transportation between tanks is long, so the surface of the wire is exposed to air for a long time, resulting in oxidation of the surface of the wire. 3. The position of the looped wire rod fluctuates on the slope of the conveyor, resulting in jamming, tangles, and tangles between the loops. The present invention solves the above-mentioned conventional problems in surface treatment equipment for wire rods that are conveyed in a horizontal loop, and achieves uniform and good surface treatment over the entire wire rod in a short process. The purpose is to provide Another object of the present invention is to provide a surface treatment device for loop-shaped wires that can perform various post-processing processes without any trouble by applying uniform and good surface treatment, and that can produce high-quality products. . In order to achieve the above object, the surface treatment device of the present invention continuously conveys the loop-shaped wire rod horizontally, and overflows the treatment liquid from the liquid spray box installed above the conveyance path to improve the surface treatment of the wire rod. The processing apparatus is characterized in that a receiving tray is provided at the lower part of the wire transport conveyor below the liquid scattering box to receive the processing liquid overflowing from the liquid scattering box and form a treating liquid layer on the conveyance path. The present invention will be explained below based on the drawings. FIG. 3a and its plan view b show a specific example of the surface treatment apparatus of the present invention. In FIG. 3, a liquid supply pipe 8 is installed with a valve 9 for adjusting the liquid supply amount on the lower side of the rectangular overflow type liquid spray box 1.
is connected, and the processing liquid 2 supplied from the liquid supply pipe 8 to the liquid spray box 1 is suppressed from ripples by the current plate 5, overflows from the weir 6, and temporarily stagnates in the receiving tray 12 below. It flows down into the liquid tank 7. As a result, the loop-shaped wire 3 conveyed by the chain conveyor 4 comes into sufficient contact with the treatment liquid 2 in the receiving tray 12 and is surface-treated. That is, the wire 3 passes through the liquid film 2' caused by the overflow of the processing liquid 2 while moving on the receiving tray 12, thereby adding the effect of being physically struck and promoting the reaction. In addition, the overflowing processing liquid flows down into the receiving tray 12 and stays there for a short time, and then overflows from the receiving tray 12 and flows down to the liquid receiving tank 7. Therefore, a ripple phenomenon occurs on the receiving tray 12, and the loop-shaped wire rod is The treatment liquid sufficiently penetrates into the dense overlapping parts on the left and right sides in the direction of movement, and a good surface treatment is uniformly applied to the entire wire. In addition, according to the present invention, the length of the process is the same as one conventional overflow type device, and about 1/3 of that of the immersion method. Because it is transported horizontally, the occurrence of jamming, tangling, and entanglement between loops is extremely reduced. Example Wire rod: wire diameter 2.0mmφ steel wire, loop diameter 800mm, conveyance speed: 3.5m/mim, saucer passage time approximately 7
Processing liquid: sulfuric acid Circulation rate 200/min Pickling was performed under the above conditions, and after the pickling, water washing was performed, and the wire surface was wiped with a flannel cloth to determine dirt (oxides) on the wire surface. The results are shown in Table 1. The conventional example in the table is a case where two conventional overflow type devices are provided, and the processing conditions are the same as those of the present invention.

[Table] In the conventional example shown in Table 1 above, the marks △ and × occur at dense overlapping parts on the left and right sides with respect to the traveling direction of the loop-shaped wire. However, it can be seen that according to the method of the present invention, even the dense overlapping parts on the left and right sides with respect to the traveling direction of the loop-shaped wire can be sufficiently treated. As explained above, according to the present invention, a horizontally placed loop-shaped wire can be subjected to uniform and good surface treatment in a short time through a short process. Furthermore, the device of the present invention has many advantages such as a simple configuration.
