Description

[Detailed description of the invention] The present invention consists of an outer cylinder and an inner cylinder, in which welding wire is wound in a coil between the inner and outer cylinders, stacked and stored, and the welding wire is entangled in the pail pack. This invention relates to a device for smoothly and continuously taking out a pail pack to the outside upper part in an untangled state.

The above-mentioned pail pack is used as a large-capacity welding wire storage container, but the wires are taken out from the pail pack in order from the top of the coiled laminate to the outside of the pail pack, and bent using a wire straightener as necessary. After removing the wrinkles,
This is done in the order that the conduit tube leads to the welding torch. Various devices have been considered for taking out the welding wire from the pail pack, but all of them tend to get tangled or tangled when taken out continuously over a long period of time, especially when taken out at high speed in response to high efficiency welding. , not satisfactory.

Especially when welding wires housed in modern pail packs twist within their elastic limits, e.g.
When a welding wire is stored with a 360° twist per turn, there is an inherent force in the wire that tends to twist it within the pail pack, and a force that tends to spread toward the outer periphery is always working, and when the wire is freed, Since the wire tends to spring upward along the inner wall of the outer cylinder of the pail pack, tangles, tangles, etc. appear more clearly when the wire is taken out.

The present invention has been made in order to eliminate the drawbacks of the conventional devices mentioned above, and its purpose is to provide a device for taking out welding wires that does not get tangled or tangled even when twisted wires are used. However, in a device for taking out a wire from a pail pack, which is equipped with an outer cylinder and an inner cylinder, and in which a welding wire is wound in a coil shape between the inner and outer cylinders and stored in a stacked manner, the inner side attached to the upper end of the inner cylinder is ring, and an outer ring attached to the upper end of the outer cylinder, the lower surface of the inner ring is located at a height equal to or higher than the lower surface of the outer ring, and there is a gap between the inner and outer rings. The purpose is to take out welding wire from.

The present invention will be described below based on embodiments shown in the drawings. Of course, the following embodiments do not limit the present invention, and various embodiments can be considered as appropriate without departing from the gist of the present invention.

FIG. 1 is a cross-sectional perspective view showing the welding wire take-out device of the present invention in use, and FIG. 2 is a cross-sectional view of the welding wire take-out device.

The pale pack includes an outer cylinder 1 and an inner cylinder 2, which are arranged concentrically, and a welding wire W is wound into a coil and stored in the space between the inner and outer cylinders. W' indicates the coiled laminated state of this welding wire.

The lower end of the inner cylinder 2 is fixed to the bottom plate of the outer cylinder 1, and a plate-shaped inner ring 7 is removably attached to the upper end by a pair of elastic fixing plates 9 that press against the inner surface of the inner cylinder 2. Also, the bottomed outer cylinder 1 of the pale pack
The open upper end of is closed with a conical lid member 3, as shown in FIG.

A hole through which a wire W passes is formed in the center top of the lid member 3 and is connected to a conduit tube 5.
Note that a wire straightener is removably attached in alignment with the hole as necessary. Further, the lid member is integrally provided with a plate-shaped outer ring 8 at its lower part. The annular space A is formed by the inner ring 7 which is removably provided at the upper end of the inner cylinder 2 and the outer ring 8 at the bottom of the lid member 3 which is removably installed at the upper end of the outer cylinder 1. and an annularly formed space located approximately at the center of the outer cylinder, that is, located at a diameter approximately midway between the inner cylinder diameter and the outer cylinder diameter.
The welding wires W, which are stacked and stored between the inner and outer cylinders while rotating around A, are taken out to the upper side and outside of the pail pack.

Furthermore, the positional relationship in the height direction between the inner ring 7 and the outer ring 8 is such that the lower surface of the inner ring 7 must be at a height equal to or higher than the lower surface of the outer ring, as shown in FIG. With this configuration, there is no problem even with twisted wires.
It becomes possible to take out from the annular space A.

In other words, the twisted welding wire housed between the outer cylinders of the pail pack has an inherent force that tends to untwist it, and tends to spread toward the outer circumference. 1
As shown in the figure, the wire tends to spring up randomly along the inner wall of the outer cylinder, but in the present invention, the outer ring blocks the upper part of the outer cylinder, thereby preventing the wire from springing up or popping out.

Further, as the stored wire is consumed and reduced, the distance between the upper end of the stack and the upper end of the pail pack increases, but at this time, a phenomenon occurs in which the wire jumps up and moves toward the inner cylinder side. As a result, the welding wire may become entangled with the outer wall of the inner cylinder at the top of the pail pack, preventing smooth removal. However, in the present invention, an inner ring is provided along with an outer ring, so that the wire can be in contact with the outer wall of the inner cylinder. The above-mentioned problems such as entanglement are prevented, and the ring is taken out upward from the annular gap formed by the outer ring and the inner ring.

Regarding the height positions of the inner and outer rings, when the wire jumps up and moves from the outer cylinder side to the inner cylinder side while contacting the bottom surface of the ring, the inner ring is set so that it does not catch on the inner ring and jump out to the top of the ring. The lower surface is regulated to a height equal to or higher than the lower surface of the outer ring. When the wire jumps up and moves from the inner cylinder side to the outer cylinder side, the bending diameter of the wire is larger than the inner diameter of the outer ring, so the wire does not get caught.

In the embodiment shown in the above drawings 1 and 2, the outer ring is attached integrally with the lid member, but the present invention is not limited to this. As long as it does not deviate from the main idea of forming a hole, which is a wire outlet, in the approximate center of the outer cylinder, it may be constructed separately from the lid member. For example, an outer ring may be sandwiched between the upper end of the outer cylinder and the lid member, and this They may be connected by a tightening band 4.

In addition, the inner ring in the above embodiment has a thicker part that contacts the upper end of the inner cylinder, and the outer ring 8
Although the facing portion is formed to have a thinner thickness, the configuration is not limited to this, and the facing portion of the outer ring 8 may be formed in a stepped shape as shown in FIG. 3a, or the facing portion of the outer ring 8 may be inclined as shown in FIG. In both cases, the lower surface of the inner ring 7 is shaped to be equal to or higher than the lower surface of the outer ring 8.

Further, the inner and outer rings are not limited to plate shapes, and may have a structure in which two ring portions having different diameters are integrally connected by an arm portion arranged radially. Further, the material of the inner and outer rings may be a metal such as steel or a synthetic resin such as vinyl chloride.

The state in which twisted welding wire is taken out by this device configured as above is explained with reference to FIG. The wire is drawn out from the upper end of the laminate, passed through the annular gap A, and further sent to a welding torch (not shown) through the hole at the top of the lid member 3 and the path of the conduit tube 5.

A wire feeding mechanism is provided on the welding torch side of the conduit tube 6, and the wire W is drawn out by this feeding mechanism. When the wire W is pulled out, since the wire W is stored in a wound state, the wire W is pulled up from the upper part of the laminate W' to the upper space 〓A while turning. At this time, as mentioned above, the twisted wire housed in the pail pack has an inherent twisting force, which causes it to spring up along the inner wall of the outer cylinder of the pail pack, but the outer ring Since it is blocked by 8, it jumps out of the pale pack,
The inner ring prevents inconveniences such as tangles, and also prevents floating wires from moving from the outer cylinder to the inner cylinder and from becoming tangled in the inner cylinder.

As a result, the welding wire W is pulled up while rotating extremely smoothly and lightly between the inner and outer rings A, and is fed into the conduit tube through the hole at the top of the lid member.

The inner ring of the wire take-out device is removably attached to the upper end of the inner cylinder, and the outer ring is detachable from the upper end of the outer cylinder.
It can be used in one pail pack, and when that pail pack becomes empty, it can be transferred to another pail pack for use.

As explained in detail above, in the present invention, an inner ring is provided at the upper end of the inner cylinder and an outer ring is provided at the upper end of the outer cylinder in the upper part of the pail pack, so that the welding wire can be sprung up and removed from the pail pack. The wire can be taken out from the annular gap located approximately at the center of the inner and outer cylinders while being smoothly rotated, while preventing the wire from becoming tangled or tangled due to flying, or entangled with the inner cylinder.

This invention is effective not only when removing ordinary wire continuously for a long time and at high speed, but also when removing twisted welding wire, and the wire can be removed without interrupting welding. It is possible to perform continuous extraction, making it an extremely practical device.
