Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automatic pickling equipment for a wire coil that performs a pickling lubrication film treatment on a coiled wire.
[0002]
[Prior art]
The automatic pickling equipment for coiled wire consists of a loop type pickling method in which the C hook and transporter are not separated, and a reciprocating acid that separates the C hook during processing and places it on a table on the processing tank. Roughly divided into washing methods.
[0003]
Of these, the former loop pickling method has the advantages listed below.
(1) Since the order in which the materials are input is the same as the extraction order on the outlet side, operation management can be performed easily, and troubles such as mixing of different materials are unlikely to occur.
{Circle around (2)} Since the conveyor and the C hook have a one-to-one correspondence, each processing time can be managed strictly, which is advantageous in quality control.
(3) Since the material is lifted at one central point, the opening is narrow, sufficient wind speed can be obtained even with a relatively small blower, and harmful acid atmosphere can be discharged outside without leaking around the equipment, effectively eliminating it A hood that can be rendered harmless by the equipment can be installed.
[0004]
On the other hand, the latter reciprocating pickling method has the following advantages.
1) In the case of materials with different processing times, the following materials can be skipped without being disturbed by the processing of the preceding materials.
2) Since the C hook is orthogonal to the traveling direction of the conveyor, the installation area is small.
3) The machine height can be lowered compared to the loop type.
[0005]
[Problems to be solved by the invention]
However, the former loop type pickling method has the following drawbacks.
{Circle around (1)} Since the processing tanks are placed vertically (the longitudinal direction is the same as the conveying direction), the line becomes longer as the number of tanks increases.
(2) 'For the same reason as (1)', the mechanical devices (vibrators, high-pressure washing equipment drive units, etc.) associated with the treatment tank are arranged directly below the transport rail, so the maintenance is poor.
(3) Since the atmosphere hood is installed, the machine height including the lifting mechanism is increased.
[0006]
On the other hand, the latter reciprocating pickling method has the following disadvantages.
1) Since it is difficult to suspend the material at one point, the opening of the lifting part is large and it is difficult to install an effective atmosphere hood.
2) 'Time management is difficult due to the interference of the transfer machine for setting the processing time of each processing tank.
3) 'If there is no strict material tracking, there is a high risk of foreign material mixing.
Thus, the conventional pickling facilities have both advantages and disadvantages.
[0007]
The present invention has been made in view of the above-described problems, and has advantages of both methods other than material jumping, that is,
B) Operational management is easy because the order of material loading and extraction is not changed.
B) Non-separation of the C hook and the transfer machine, and strict management of each processing time is possible.
C) An effective atmosphere hood can be installed with the lifting part of the C hook as one central point.
D) Reduce the machine height and minimize the plane installation area.
E) Maintainability is improved by installing drive parts such as vibrators and high-pressure washing equipment outside the line.
It aims at providing the automatic pickling equipment for wire coils which can satisfy the above points.
[0008]
[Means for Solving the Problems]
In order to achieve the above-described object, the automatic pickling equipment for a wire coil of the present invention is configured such that the C hook is orthogonal to the traveling direction of the conveyor. In this way, the material charging order and extraction order are not out of order, operation management is easy, strict management of each processing time is possible, and it is possible to install a hood that can be made harmless with an exclusion device effectively However, the line length can be shortened.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The automatic pickling equipment for wire coil according to the present invention includes pickling, water washing, lubrication film treatment, drying and loading and unloading device of the coiled wire on the C hook below the loop-shaped transport rail, and has an elevating mechanism. In a loop-type pickling facility that performs pickling lubrication film treatment of a coiled wire while traveling along the transport rail with a non-separable C hook transporter, the C hook is held by the transporter from the transporter. The guide rail mounted in a hanging shape is a sliding or rolling member installed on the C hook side and is held in a sandwiched manner so that it can be moved up and down freely, and the conveyor is parallel to the loop-shaped conveyor rail. Thus, the posture is maintained by the traveling guide rail laid, and the C hook is orthogonal to the traveling direction of the conveyor.
[0010]
In the automatic pickling equipment for wire coil according to the present invention, the direction of the C hook is made orthogonal to the traveling direction of the transfer machine, so that the treatment tank can be placed horizontally and the line length can be shortened.
[0011]
In addition , central one-point suspension can be realized regardless of the unbalanced load due to the loading state of the coiled wire on the C hook.
[0012]
In addition, if two or more guide rails are arranged in the direction of travel of the conveyor and the distance between the two or more guide rails is larger than the outer diameter of the wire coil, the direction of travel when the C hook is raised It becomes possible to wind up the wire coil between the guide rails arranged before and after, and the machine height can be lowered.
[0013]
Moreover, when it is set as the structure which can cancel | release connection with a conveyance machine and C hook, when vibrating to a coil-shaped wire in each processing tank, a vibration will not be transmitted to a conveyance machine.
[0014]
In the above-described automatic pickling equipment for wire coils of the present invention, when washing, a coil rotating device that once receives the wire coil from the C hook and rotates it forward and backward on the spot, against the wire coil suspended on the C hook the high-pressure cleaning device for cleaning the inner and outer surfaces of the wire coil and moved closer Te when installed on both sides of each processing tank, coils rotating device, be located a drive unit of the high-pressure washing device to the outside of the transport rail This makes it possible to improve maintainability.
[0015]
Further, in the above-described automatic pickling equipment for wire coils of the present invention, when the coiled wire rod loading device and the unloading device are independently installed at arbitrary positions, the loading zone and the unloading zone at one end of the loop. This makes it possible to reduce the installation area and centralize operation personnel.

Attached devices such as a coil rotating device 12 that is once received from the C hook 9 and rotated forward and reverse on the spot are provided, and a loading device 6 and an unloading device 7 for the wire coil 5 are installed before and after these processing tanks 3. .
[0018]
Among these, as shown in FIG. 3, for example, the high-pressure washing apparatus 11 applies a wire rod to a carriage 11 b that is moved by a motor 11 a so as to be able to move toward and away from the wire rod coil 5 suspended by the C hook 9. When moving closer to the coil 5, the inner spray 11 c supported in a cantilever manner so as to be inserted into the inner surface of the wire coil 5, and so that the wire coil 5 can be inserted when moving closer to the wire coil 5. A ring-shaped outer spray 11e with a part of the upper side attached to the tip of a support rod 11d supported in a cantilever shape is arranged, and the inner spray 11c and the outer spray 11e are connected to the inside of the tank 11f. The washing water 11g is supplied through a pipe 11i by a pump 11h.
[0019]
Similarly, as shown in FIG. 3, the coil rotating device 12 is a motor that can move toward and away from the wire coil 5 suspended on the C hook 9 as in the high pressure cleaning device 11 described above, for example. A roll 12d that can be rotated forward and backward by a motor 12c is supported in a cantilever manner on a carriage 12b that is moved by 12a, and the wire coil 5 is suspended while being lowered by a C hook 9 while being suspended. After that, the carriage 12b is moved closer to insert the roll 12d into the wire coil 5.
[0020]
Next, after the C hook 9 is lowered to the lower limit position and the wire coil 5 is supported by the roll 12d, the carriage 11b of the high pressure washing device 11 is moved closer to the wire coil 5 and the pump 11h is operated simultaneously. . Then, the carriage 11b is moved toward and away from the wire coil 5 while rotating the roll 12d forward and backward, and cleaning water is sprayed from the inner and outer sprays 11c and 11e to clean the inner and outer surfaces of the wire coil 5.
[0021]
Reference numeral 8 denotes a C hook non-separating type transporter that is guided by the transport rail 2 and moves, and is provided with a lifting mechanism and a control device (not shown) below the suspension type transport carriage 8a. ) Is installed. In the lower part of the platform, two guide rails 8b for guiding the up-and-down movement of the C hook 9 arranged perpendicular to the traveling direction of the transporter 8 are fixed in a drooping manner, for example, before and after in the traveling direction, In order to prevent the platform from being tilted, a guide roller 8c for causing an unbalanced load to be applied to the traveling guide rail 10 arranged in parallel with the transport rail 2 is installed so as to be freely rotatable.
[0022]
The C hook 9 is suspended from an elevating block 8e suspended from a hoisting device installed on the platform via, for example, a wire rope or a roller chain (hereinafter simply referred to as a “wire rope”) 8d by an inverted hook-shaped connection. It has been. The elevating block 8e includes, for example, rollers 8f that hold the guide rail 8b in a sandwiched manner on the front and rear sides in the traveling direction, and the C hook 9 suspended from the elevating block 8e is guided by the rollers 8f. Even if it receives an unbalanced load, it moves up and down without tilting.
[0023]
As shown in FIG. 2, for example, the C hook 9 has a U-shaped steel rod 9 a made of a U-shaped steel plate that has an umbrella shape at the top and is flipped up at both ends slightly and whose length is longer than the width of the treatment tank 3. In addition, a lifting member 9b having an L-shape is bolted, and the wire coil 5 into which the lifting member 9b is inserted by lifting the top portion of the long rod 9a with the hardware 8ea fixed to the lifting block 8e. Is designed to move up and down. By adopting such a configuration, it becomes possible to easily replace the C hook 9 (lifting member 9b) that has been corroded due to long-term use.
[0024]
In this embodiment, as shown in FIG. 2, the metal piece 8ea has a structure in which an engaging claw is protruded to face a U-shaped lower end portion opened in the lower side, and the metal piece 8ea An upper flange of an H-shaped steel forming a long rod 9a is inserted into the internal space. Therefore, normally, the upper flange of the H-shaped steel is joined with the weight of the C hook 9 in contact with the engagement claw of the metal piece 8ea, and the wire coil 5 is suspended and conveyed.
[0025]
On the other hand, when the wire coil 5 is lowered into the processing tank 3, the overhanging portion of the long rod 9a is placed on the cradle 4a of the vibrator 4 installed on both sides of the processing tank 3, and the lifting block The elevating block 8e and the C hook 9 are further lowered until the elevating block 8e and the C hook 9 can be released, thereby releasing the coupling between the elevating block 8e and the C hook 9 from the vibrator 4 disposed on both sides of the processing tank 3. The vibration is prevented from being transmitted to the elevating block 8e and the upper structure.
[0026]
Further, in this embodiment, the distance between the guide rails 8b arranged in a drooping manner before and after the traveling direction is larger than the outer diameter of the wire coil 5, for example, the same as the width of the treatment tank 3, and the C hook 9 is raised. In this example, the wire coil 5 can be wound up between the guide rails 8b arranged before and after the traveling direction, and the machine height can be lowered.
[0027]
If the guide rail 8b is made of a corrosion-resistant material such as stainless steel, the illustration is omitted. However, since the guide rail 8b can enter the hood from the upper opening of the atmosphere hood, the guide rail 8b does not tilt even if it receives the above-described uneven load. Combined with a configuration capable of moving up and down, an effective atmosphere hood can be installed on the treatment tank 3.
[0028]
By the way, according to the automatic pickling equipment for wire coils of the present invention having the above-described configuration, conventionally, 17 treatment tanks, 3 dryers capable of treating 3 coils, 1 loading device and 1 unloading device each. Based on the length of the loop-type pickling equipment that required a distance between the centers of the loops of 91 m, the number of treatment tanks was 22, the dryer was capable of treating 4 coils, the loading device and the unloading device. Even with equipment equipped with 1 each, the distance between the loop centers can be reduced to 38.3m, and the total building area including the attached devices can be more than 1000m ² and less than 1/2 of the conventional equipment. Became. Also, the mechanical height of the conventional loop-type pickling equipment, which required a height of 9.5 m below the transfer rail, was improved to 7.9 m.
[0029]
【The invention's effect】
As described above, according to the automatic pickling equipment for wire coils of the present invention, the distance between the centers of the loops can be made compact by making the direction of the C hook orthogonal to the loop-shaped transport rail, and all the devices including the attached devices can be made. Since the building area can also be reduced, the production volume can be increased by increasing the number of treatment tanks and the types of film treatment can be increased even though the quality is equivalent. Then, for the same reason, coils rotating device, it is possible to install the drive unit such as a high-pressure cleaning device outside the transport rail can improve the maintainability.
[0030]
Moreover, when the interval between the guide rails arranged in a drooping manner before and after the traveling direction is made larger than the outer diameter of the wire coil, the machine height can be made lower than that of the conventional loop pickling equipment.
[0031]
Moreover, when it is set as the structure which can cancel | release connection with a conveyance machine and C hook, when a coiled wire is vibrated in each processing tank, a vibration will not be transmitted to a conveyance machine.
In addition, if the treatment tank is roughly divided into a pickling section and a film treatment section, and the curve of the traveling rail is placed between them, the loading and unloading zones can be concentrated at one end of the loop, reducing the installation area. And centralized operation personnel.
