Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a welding wire storage device which can be used for a long time without deterioration and deformation during handling, storage, transportation and use of the welding wire.

[0002]

2. Description of the Related Art Generally, in an automatic or semi-automatic welding apparatus using a welding wire, a large capacity for storing and maintaining a supply wire and shortening a replacement time has been developed. Speeding up the welding work by increasing the capacity is also an essential requirement. Accordingly, the use of robots has been increased due to the speeding up of welding work, and a method of storing and supplying welding wires in a large capacity has been regarded as important in order to improve work efficiency.

[0003] Usually, a welding wire stored in a large-capacity container is dropped while being bent in a loop shape and stacked and stored in units of 200 kg or 300 kg. And, since the upper end of the laminated wire is simply placed on the upper end of the lamination surface without using a special fixing means in order to simplify the initial pulling out, even if a slight vibration occurs, it jumps up or pulls out When tension (te
Even the addition of nsion) causes the subsequent wire to jump, which causes entanglement and entanglement between the welding wires, making smooth extraction very difficult.

Therefore, as shown in FIGS. 1 to 5, a holding member (4a,
4b, 4c, etc.) is widely applied as a means for preventing jumping. The above-mentioned restraining member prevents the body from jumping up due to its own weight and the load due to the spring in the weight direction, frictional resistance against the inner surface of the container, etc. It is configured to hold down.

[0005] Such a holding member is a cylindrical container (2).
The welding wire (1) in the inside is wound up and stored, and an annular pressing member (4a, 4b, 4c, etc.) is provided at the upper end of the laminate.
Japanese Utility Model Publication No. Sho 63-20679 is known in which a pressure member (5a, 5b, etc.) and the like are placed. Although such a configuration is somewhat effective as a means of preventing the welding wire from jumping up, there is a problem in that the stacked welding wire stack is entangled (Tangle) due to shaking when transporting and handling the welding wire. It is pointed out.

In Japanese Patent Publication No. 59-8474, as shown in FIG. 2, an inner tube (3) is set up vertically in a cylindrical container (2), and a space is provided between the container (2) and the inner tube (3). A method is disclosed in which the welding wire (1) is stacked and stored and pulled out. However, the gap (10) between the stacked and stored welding wire (1) and the inner pipe (3) is large, and the wire is shaken during transportation. However, since the effect of supporting the laminated welding wire (1) is extremely insufficient, the effect of preventing entanglement cannot be expected.

The above method and the like have been devised assuming that the welding wire (1) is entangled when the welding wire (1) is pulled out during a welding operation. The fundamental problem that entanglement occurs during transportation or handling is described below. Not considered at all. Further, as shown in FIGS. 2, 4 and 6, there is a problem that the welding wire (1) is caught in the gap between the circular plate (11) on the floor of the storage container (2) and the lower end of the inner tube (3). Otherwise, the supply will be interrupted, or the metal material (9a, 9b) or the like fixing the inner pipe (3) will cause an electrical short between the external welding device and the welding wire, causing the welding wire to burn out. Also, the problem that the welding work is interrupted due to the earth leakage is indirectly caused.

In the method of fixing the welding wire after storing the welding wire in a large-capacity storage container, the upper laminating surface of the welding wire is pressurized as a sponge or a polyurethane material (5a), or a square having a different size is used. Alternatively, an elastic rubber wire is hung on a circular carton (carton) pressing member, and placed on the lamination surface of the welding wire so as to vertically overlap with each other, and as shown in FIG. An upper pressurization method of a laminated surface which is pressurized by elastic force, and a hook (8) is attached to the center of a plate material (11) on the inside of a storage container and a floor surface, and a welding wire (1) is provided on a laminated surface to prevent entanglement. (4
a, 4b, 4c, etc.), an iron plate (6a) or an iron hook (6b) is hung on the upper end surface thereof, and an elastic rubber wire (7b) is hung on the internal floor surface hooking portion (8) of the storage container. ) Or a laminate (tensile pressing) fixing method using a spring (7a) or the like.

However, the pressurizing method on the upper surface of the lamination surface reduces the bulk due to the looseness of the laminated body during transportation, thereby deteriorating the pressing effect, and the amount of lamination is limited to the upper pressure range of the lamination surface. In this case, a problem arises in that the elastic spring (7a) and the rubber wire (7b) are cut off, so that the range of use is extremely limited. Further, although the laminated body tension pressurizing method is a generalized method, the method is not applied to the entanglement preventing device (4a, 4a).
b, 4c, etc.), and the fixing means is provided with a entanglement preventing device (4a, 4b,
4c, etc.), the elastic force is low enough to prevent the detachment of the welding wire laminate. There was no.

The spring (7a) or the rubber wire (7)
Although a method of pulling by increasing the pulling force in b) is conceivable, the problem of distortion of the iron plate (6a) or the iron latch should also be considered. Further, the provision of the inner pipe (3) in the welding wire storage container (2) makes it almost impossible to employ a laminated body tension pressurizing method. Therefore, the pressurization method on the upper part of the lamination surface is mainly used when the welding wire container (2) is composed of an outer tube and an inner tube, and the laminate tension pressurization method is that the container (2) is formed only from the outer tube. Mainly used when it comes to

[0011] The storage amount of the welding wire storage container (2) is specified in the Japanese Industrial Standard JIS Z3391 up to a maximum of 400 kg, although there is a difference depending on the standard of the storage container (2). Although this is the basis for setting the safety factor to 4 or more from the relationship between the carrying ring and the winding weight at the time, the storage amount of the welding wire is generally set to 350 kg or less. This is because when the storage amount is increased, the connection between the transport ring (15) and the storage container (2) as shown in FIG. 7 is made up of the bolt and the nut (12), so that the bolt and the nut (12) are connected. It is often understood that the tensile strength of the storage container (2) is sufficiently considered at the same time as the bonding force is weak, but the tensile strength of the storage container (2) decreases due to moisture absorption from the outside. Therefore, the safety factor 4 cannot be satisfied, and a serious accident such as a crash may occur during transportation work.

However, it is a reality that some storage containers (2) that cannot satisfy the safety factor 4 even with a storage capacity of 300 kg or 350 kg are informally used. Of course, a method of increasing the storage amount by satisfying the safety coefficient by increasing the thickness of the storage container (2) can be considered, but it is generally impossible to execute the method for economic reasons.

Further, a storage container (2) stored in a large capacity.
As shown in FIG. 8, a pallet and a storage container are mounted on a pallet (22) with a steel cord or a cord (14) of a synthetic resin such as polypropylene, polyethylene, or the like to prevent deformation due to impact or guidance during transportation. However, not only the storage container cannot be strongly tightened because the storage container is easily distorted by the pressure of the strap, and the storage container (15) is used for the transport ring (15) between the storage containers (2). 2) The gaps could not be adhered, and problems were always pointed out during transportation.

[0014] Further, in the preservability of the welding wire stored as a large capacity, unlike the small storage method which is consumed within a few days or hours, the welding wire is used for several days or several months, Deterioration and deformation occurred during the distribution process and long-term storage for several months to several years, and the original purpose of the welding wire could not be achieved.

The welding wire storage container (2) used partially has a protective film made of a thin thin transparent synthetic resin or the like formed on the outer or inner surface of the outer tube to prevent moisture absorption from the outside. However, as shown in FIG. 18, the joint between the outer tube (2) and the floor plate (11) is not waterproofed and its effect cannot be expected, and the floor plate (11) is not used. The protective film of (1) is not considered at all and is exposed on the ground surface, so that it may be difficult to use the welding wire because it rusts on the welding wire due to moisture absorption.

On the other hand, in order to form the outer tube and the floor surface into one structure, a method of injection molding with a synthetic resin such as plastic to prevent moisture absorption from the outside can be considered.
Condensation due to the temperature difference between the welding wire stacked and stored in the storage container and the outside of the storage container has a tremendous effect on the generation of rust on the welding wire. Therefore, most of the welding wire container (2) is made of pulp, and it is recognized that it is important to perform a moisture-proof treatment for preventing moisture absorption.

Then, while the welding wire is supplied from the welding wire storage container (2) to the welding machine, the amount of the welding wire maintained in the storage container (2) gradually decreases and eventually is completely consumed. In automatic welding using robots, it is difficult to estimate from the outside when the welding wire will be completely consumed. Significant loss of wire appears. In order to prevent such a problem, in Japanese Utility Model Publication No. 3-38208, a counter for displaying the remaining amount is attached to check the remaining amount of the welding wire. −
In Japanese Patent No. 100823, various methods for confirming the remaining amount of the welding wire by attaching or using a magnet are used. However, such methods and the like must be separately attached to the storage container or provided at every use. Currently, most of them are not used because of inconvenience in use.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the drawings. As shown in FIG. 10, the welding wire storage device of the present invention is provided with an inner pipe (3) and an outer pipe (2), and stores a welding wire (1) between the inner pipe (3) and the outer pipe (2).
This is a device for fixing and closing the lid (31) to the container. According to the present invention, two long holes (24) are formed vertically in the inner tube (3) of the storage container, and the lower end of the inner tube (3) is cut vertically several times to form an incision (25). , The incision (25)
Into the inner peripheral surface.

Then, on the lower surface of the circular plate (11) of the circular bottom plate (11 ') composed of the circular plate (11) and the donut-shaped plate (26), a dampproof land (30) (film, synthetic resin,
After joining liquid coating material or film, synthetic resin, paper with liquid coating material, etc.), the donut-shaped plate material (26) constituting the circular bottom plate (11 ') on the upper end surface matches the original line. The lower end of the inner pipe (3) is placed vertically in the hole of the donut-shaped plate (26), and the inner pipe fixing plate (19) is inserted into the inner pipe (3) and cut open several times. After being placed on the incision (25) folded into the inner peripheral surface, it is joined and fixed to the circular plate (11). Thus, the inner tube fixing plate (19), the incision (25), and the circular plate (1)
The method of bonding and fixing 1) can use a bolt and a nut, or can use a stapler or a bonding process using an adhesive or the like.

Further, the circular bottom plate (11 ') may be constituted by separating the circular plate material (11) and the donut-shaped plate material (26) or integrally as described above. It may be composed of only (11). However, when the circular bottom plate (11 ') is composed of only the circular plate material (11), the moisture-proof paper (30) is attached to the floor of the circular plate material (11), and the inner pipe (3) is provided at the center of the upper end surface. Can be fixed vertically.

At the upper end and the lower end of the outer tube (2), annular projections (37) are formed so as to face inward, and the circular plate (11) of the vertically fixed inner tube (3) is formed. The outer tube (2) is sandwiched so that the inner peripheral surface below the lower end protrusion (37b) of the outer tube (2) is in contact with the circumferential surface of the outer tube (2). The steel rings (16a) (16b) are fixedly connected to the outer peripheral surfaces of the projections (37a) (37b) at the upper end and the lower end of (2).

Further, as shown in FIG. 16, a carrying ring (15) is attached to both ends of the upper end of the outer tube (2) by rivets (1).
As shown in FIG. 20, a fixed hole is formed at a lower end of the outer tube (2) at a fixed size, and a transparent window (18) is attached.

The inner peripheral surface of the outer tube (2) is covered with a moisture-proof paper (3).
0) (Film, synthetic resin, liquid coating agent or paper on which film, synthetic resin, liquid coating agent, etc. are attached), and the outer surface of outer tube (2) is moisture-proof printed with trademark (20a). A cover (20) (moisture-proof paper, film or synthetic resin-coated paper, manila paper, etc.) is wrapped, and a carrying ring (15) is attached to the upper end of the printed trademark (20a) and the opposite side, and an outer tube (2). Solid body (silicon solid body, fixed body, rubber packing, etc.) in the gap between the steel ring (16b) connected to the lower end of the base and the moisture-proof paper (30) attached to the bottom of the circular bottom plate (11 '). This is the structure of the gap partition subjected to (17). Further, the outer cover (20) or the moisture-proof paper (30) is attached by coating the outer peripheral surface of the outer pipe (2) or the circular floor surface of (11 ') with a liquid coating material (not shown). Needless to say, it is possible to obtain the same effect.

In the welding wire storage device of the present invention, an annular portion (28) is fixed to the center of a circular bottom plate (11 ') attached to the lower ends of the outer pipe (2) and the inner pipe (3). The ring portion (28) is connected to the upper end of a fixing member (34) through a tension member made of a band made of an elastic material, and a lower portion of the fixing member (34) is connected to a lamination of the welding wire (1). The protective plate material (33) is attached during the pressing, and the laminated body of the welding wire (1) is pressed downward, whereby the laminated body of the welding wire (1) is unbalanced in weight due to play.
It is configured to prevent deformation and entanglement of the laminated form due to uneven load, impact and the like.

In the above description, the tension member made of an elastic substance comprises an elastic band (35) and an elastic member (36), and the elastic band (35) and the elastic member (36) are contracted by a rubber band, a rubber wire, a spring or the like. In particular, the elastic band (35) is a structure that is easy to fasten and disassemble (such as a band to which a binding device is attached, a band to which a latch is attached, a string or a spring, etc.). It is more desirable to use the one-touch elastic band (35).

That is, after the welding wire (1) is housed and laminated inside, a protection plate (33) or a holding member (4a, 4b, 4c, etc.) as shown in FIG.
And a slot (24) formed perpendicular to the inner tube (3).
Protective plate (3)
3) Position at the upper end. At that time, the interval between the stacked body of the welding wire (1) and the inner tube (3) housed in a stacked state must be maintained at 1.5 cm or less, and when the gap exceeds 1.5 cm or more. When the laminated body of the welding wire (1) in the laminated storage is carried and moved, the lamination causes deformation and entanglement of the laminated form due to unbalanced weight, unbalanced load, impact, and the like, and a large number of glass balls in addition to the suppressing member. When an anti-entanglement body (not shown) made of is arranged on the upper end surface of the laminate and used, a large number of glass balls (not shown) are used to store the laminate of the welding wire (1) and the inner pipe (3) in the laminate storage. This causes a difficult problem in use due to being caught or flowing down in the gap. It usually has a glass ball (not shown) diameter of 1.6 cm to 2.5 c
m.

Further, when the diameter of the inner tube (3) is not so large as to be close to the welding wire (1) in which the welding wire (1) is stacked and stored, the welding wire (1) is also stored. ) Are stacked and housed in the gap between the stacked body of the welding wire (1) and the inner pipe (3), and the stacked body of the welding wire (1) and the inner pipe (3) stacked and stored to flow down. The inner tube (3) is desirably configured so that the gap between the inner tube (3) and the inner tube (3) is kept at 1.5 cm or less. Further, an annular portion (28) is formed at the center of the circular bottom plate (11 '),
An elastic body (36) constituting a tension body is hung on the ring portion (28), and the one-touch elastic band (35) is connected to the elastic body (36) and the fixing portion (34) at the central projection (34 '). To fix it in a double-stranded structure.

Therefore, the tension member and the protective plate (3)
(3) and the fixing wire (34), etc., strongly press the welding wire (1) inside the outer tube (2),
A few moisture proof materials (not shown) and a manual (not shown) describing the use of the present invention are put into the inside of 3), and the outer tube (2) is closed by the outer tube cover (31). It is a structure fastened by a clip (32).

In the above description, the protective plate (33) is the same as that shown in FIG.
As shown in detail in FIG. 4, the outer tube (2) is made of a plurality of arc-shaped plate members forming an acute angle and forming a pair with each other.
When disposed above the welding wire (1) between the inner pipe (3) and the inner pipe (3), the inner peripheral surface thereof substantially corresponds to the outer diameter of the inner pipe (3), and the outer peripheral surface thereof corresponds to the outer pipe (3). This is substantially the same as the inner diameter of 2). Further, the elastic body (36) may be the same rubber band as the elastic band (35), a spring or the like.

The welding wire storage device of the present invention having the above-described structure is a laminate in which the welding wire (1) is stacked and stored between the outer pipe (2) and the inner pipe (3), and the inner pipe ( By eliminating or minimizing the interval (10) with respect to (3), a protective plate (33) or a holding member (4) is provided at the upper end of the laminate.
a, 4b, 4c), etc. are placed, and fixed and restrained (34) are fitted into vertical slots (24) formed on both sides of the inner pipe (3), respectively, and positioned at the upper end of the protective plate (33). .

Then, the elastic member (3) is attached to the ring portion (28) of the floor.
6), the elastic body (36) and the one-touch elastic band (35) of the central protrusion (34 ') of the fixing restraint are connected to each other to strongly pull and apply as a tensile body having a double chain structure. During transportation and handling, it is possible to prevent the laminated body of the welding wire (1) from eccentricity in weight due to play, entanglement (Tangle) due to deformation of the laminated state due to imbalanced load, impact, and the like, jumping, and the like.

Here, the size of the inner pipe (3) is shown in FIG.
As shown in FIG. 0, the inner tube (3) is configured to have the same inner diameter as the stacked body of the welding wire (1), and the inner tube (3) acts as the central axis of the stacked body of the welding wire (1) during transportation. The shaft serves to support the welding wire (1) laminate.
Further, the protection plate (33) or the holding member (4a, 4b,
4c) and the like, when being strongly pulled and pressurized by the fixing restraint (34), a large number of glass balls in addition to the restraining members (4a, 4b, 4c) to prevent damage to the lamination surface of the welding wire (1). (Tangle prevention device) (not shown)
After removing 4), it can be used by arranging it on the upper end surface of the lamination of the welding wire (1).

Further, the floor of the lower end of the laminated body of the welding wire (1) is formed higher than the lower end of the inner pipe (3), so that the welding wire (1) is lower end of the inner pipe (3). And prevent the welding work from being interrupted by the occurrence of a short circuit caused by energization, and at the same time, make the inner pipe (3) less than 15 cm in height difference between the outer pipe (2) and the inner pipe (3). By configuring the height of (3), the storage amount can be increased.

During the welding operation, the welding wire is guided from the upper end of the inner pipe (3) while being sent out, and works so that the welding wire is smoothly sent out without being entangled in distortion. If the height of the inner pipe (3) is higher than the height of the outer pipe (2), the welding wire may be hung on the upper end of the inner pipe (3) during welding work, or the welding work may be interrupted due to friction. Delivery becomes unstable, and easy welding work cannot be expected. Therefore, it is desirable that the inner tube (3) is configured to have the same height or lower than the height of the outer tube (2). However, even if the inner tube (3) is configured to be equal to or lower than the height of the outer tube (2), the difference in height between the outer tube (2) and the inner tube (3) exceeds 15 cm. In the case, the welding wire is not guided from the upper end of the inner tube (3) while being sent out during the welding operation, and is distorted by the steel properties of the welding wire itself or loosely entangled with each other. It is desirable that the difference in height from (3) be approximately 15 cm or less.

Further, the tension member constituted by the double chain structure buffers the movement of the welding wire (1) during transportation and handling, and can be easily fastened and separated by one touch. . In addition, the one-touch elastic band (35) can be adjusted in tension so as to strongly pull between the fixed holding part (34) and the ring part (28). Therefore, the fixing restraint (34) is provided so that the laminated body of the welding wire (1) is not deformed by distortion even if it moves freely, as shown in FIG.
Lx × Pma by the refraction test (b) as shown in FIG.
It is desirable that x be maintained at 1,000 kgf · cm or more. Here, Lx is the diameter of the laminate inner diameter, and Pmax is the maximum refraction load at the diameter of the laminate inner diameter. Further, it is more preferable that the fixing restraint (34) is constituted by a cross section of a "U" shape because resistance against a refracting load acts greatly.

At the same time, a projection (34 ') is formed at the center of the fixing restraint (34), and the one-touch elastic band (35) is located at the center so that the tensile force is evenly distributed to the fixing restraint (34), and Sometimes it also acts to prevent the one-touch elastic band (35) from coming off the fixed restraint (34).

The inner and outer peripheral surfaces of the outer tube (2) are respectively composed of a moisture-proof paper (30) and a moisture-proof cover (20), and the moisture-proof paper (30) is placed on the outer surface of the circular bottom plate (11 '). By attaching, the outer tube (2) and the circular bottom plate (11 ') are covered with the moisture-proof paper (30), and the solid material (17) partitions the gap between the steel rings (16b) connected thereto with the solid body (17). Water absorption from the outside can be prevented, and the storage stability can be maintained during long-term storage and use.

On the other hand, the moisture-proof cover (20) has a special surface treatment and, unlike ordinary pulp, has a low moisture permeability.
The inner peripheral surface and a circular bottom plate (11 ') and the double moistureproof effect with lower moisture-proof paper (30), several desiccant for the volume of the outer tube (2) 600 g / m ³ or more is maintained in So as to remove dissolved moisture in the storage container. The desiccant is known as a desiccant, and also releases a part of the absorbed moisture after a long period of time. Therefore, the minimum amount of storage of the outer tube (2) is considered in consideration of the released moisture. It is desirable to maintain the volume at 600 g / m ³ or more.

On the other hand, with respect to the storage amount of the welding wire, the connection between the bolt and the nut (12) is released by firmly fixing the carrying ring (15) with the rivet (13), and the outer tube is pulled when the outer tube is pulled. (2) It is possible to solve the problem that the load concentrates on the bolt (12) and breaks, and the weight can be increased up to 450 kg. When the tensile breaking load test was conducted according to the test method of Japanese Industrial Standard JIS Z 3391, the maximum tensile breaking load of the outer tube (2) was 9
This is because it is maintained at 00 kgf or more and satisfies the safety factor of 4. In other words, the rivet (13) prevents the bolt and nut (12) from being uncoupled together with the bolt and the nut from being unable to maintain a constant coupling force, and acts to disperse the load when the tension is maintained while maintaining the strong coupling force. .

Further, as shown in FIG.
5) The transport ring (15), the trademark (20a), and the product name identification label (21) are mounted on a pallet (23) by vertically attaching the trademark (20a) and the product name identification label (21) on a straight line. It is possible to position the pallet (23) and the carrier ring (1) as shown in FIG.
By tightening (strap) 5) through a rigid material string or a synthetic resin string (14) such as polypropylene, polyester, etc., the action of reducing the movement during transport and handling is achieved.

Further, a transparent window (1) is provided at the lower end of the outer tube (2).
