Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a welding wire product, and more particularly, to welding for transfer in which a plurality of spools around which a welding wire is wound, that is, welding wire spools, are packed in one set for transportation. Regarding wire products.

[0002]

2. Description of the Related Art Conventionally, a dumbbell box is placed on a transfer pallet, and a welding wire spool is lowered from the upper opening of the dumbbell box with its central axis being vertical, and For example, 5 flanges are stacked in a column shape with the flanges horizontal, and 5 × 8 welding wire spools are housed in a dumbbell box so that, for example, 8 cylinders stand vertically. A rust preventive paper is inserted between the stacked flanges, and a square tube of Danboru paper is inserted into the space between the cylinders to fill the space between the spools. The pallet and the cardboard box are integrally bound by a cross (a plurality of sets) of packing bands. This band prevents the load from falling while moving.

[0003]

Since the welding wire spool is made horizontal (the central axis of the wire winding is vertical) and lowered from the upper opening of the dumbbell box to the bottom, the automatic welding wire spool packing operation is not performed. It's complicated. Moreover, the positioning of the welding wire spool in the dumboll box must be accurate. If the positioning is inaccurate, the outer shape of the box will collapse from the rectangular parallelepiped, a strong local force will be applied during the transfer to break the box, or it will deform further, eventually causing the load to collapse. . Therefore, the mechanism of the automatic packing machine is relatively complicated, the packing work efficiency is low, and the cost of the automatic packing equipment is high.

SUMMARY OF THE INVENTION It is an object of the present invention to simplify the packaging of a welding wire spool for transportation and to prevent the load from slipping.

[0005]

The welding wire product for transfer of the present invention comprises a pallet; a groove having a rectangular parallelepiped outer shape, extending parallel to one side of the rectangular parallelepiped, and having a semicircular cross section, and a groove opened on the surface. A plurality of splines in which grooves opened on the back surface are alternately distributed at a predetermined pitch in the extending direction of the other side orthogonal to the one side.
The spool support is loaded on the pallet such that the groove opened on the front surface of one spool support faces the groove opened on the back surface of the spool support above the spool support. Piles; and in the cylindrical space formed by the grooves opened on the back surface of the upper and lower spool supports and the grooves opened on the front surface of the piles, the central axis is parallel to the one side and the layers are stacked side by side. A plurality of welding wire spools, each of which is coiled with a welding wire.

[0006]

[Operation] One spool support (first support) is placed on a pallet, and the flange is made vertical (the wire winding center axis is horizontal) and welded to the groove opened on the surface of the first support. The wire spool is inserted, and a plurality of welding wire spools are loaded side by side in the direction in which the groove extends. Since the groove is open in the surface of the support, such charging is easy and the positioning of the spool is precise.

Next, another spool support (second support) is formed so that the groove opened on the back side thereof receives the welding wire spool already inserted in the groove of the first support. , On the first support. Then, with the flange vertical to the groove opened on the surface of the second support, the welding wire sp
And a plurality of welding wire spools are loaded side by side in the direction in which the groove extends. In this way, the required number of spool supports are vertically laminated. The spool support has a rectangular parallelepiped outer shape, extends parallel to one side thereof, and has a semi-circular cross-section having a groove open to the front surface and a groove open to the back surface,
Since these grooves are alternately distributed at a predetermined pitch in the extending direction of the other side orthogonal to the one side, a plurality of welding wire spools are arranged side by side in a columnar shape in the pile of the support on the pallet. A plurality of horizontally existing rows are arranged at a predetermined pitch, and any of the rows is a cylindrical space between the lower spool support (first support) and the upper spool support (second support). Will be located inside. In the extending direction of the side-by-side rows (direction in which the grooves extend) and in the horizontal direction orthogonal thereto, the welding wire spool (the side-by-side row) has a lower spool support (first support) and an upper spool. Support (second support)
Since it is an interposer that couples (engages or locks),
The lower spool support (first support) and the upper spool support (second support) are less likely to cause relative positional displacement in the horizontal direction, and therefore the pile support piles. Is less likely to be overloaded.

Other objects and features of the present invention will become apparent from the following description of embodiments with reference to the drawings.

[0009]

FIG. 1 shows the appearance of an embodiment of the present invention. Six welding wire spool supports (hereinafter referred to as "dunnage") 2a to 2f are loaded on the pallet 1, and these pallets 1 and dunnages 2a to 2f are heat-shrinkable resin sheets tightened on their four side surfaces. -Packed with grate 10.

FIG. 2 is an enlarged cross section taken along line 2A-2A of FIG.
FIG. 3 shows an enlarged plane (a), a front surface (b) and a right side surface (c) of one dunnage 2b. Dunage 2b has
As shown in FIG. 3, there are grooves 7a, 7b and 8a, 8b having a semicircular cross section that open to the surfaces 3 and 4 and extend parallel to one side 5, and these grooves 7a, 7b, 8a, 8b are The pitch is equal in the direction in which the side 6 orthogonal to the side 5 extends, and the dunnage 2b
A plan view of the front surface and a plan view of the back surface thereof have the same shape when the latter is rotated by 180 degrees. Six dunnages 2a to 2f shown in FIG. 1 have the same shape, dunnages 2b, 2d and 2f have the same posture, and dunnages 2a, 2c and 2e have dunnages 2b, 2d as shown in FIG. And 2f inside out and 1
It corresponds to the posture rotated by 80 degrees. Dunedge 2b, 2d
And 2f and the dunnages 2a, 2c and 2e are alternately stacked in the height direction, so two cylindrical spaces are formed between adjacent dunnages (for example, 2a and 2b).
Eight welding wire spools are stored side by side in each of the cylindrical spaces, as if the flanges of adjacent spools were brought into contact with each other to form a single cylinder. A welding wire spool is one in which a welding wire (product) is wound around a spool having a cylindrical center and having flanges at both ends thereof (the cylinder). In FIG. (9ai, etc.) are shown by hatching.

FIG. 4 shows the two upper and lower dandy shown in FIGS. 1 and 2 in contact with each other. The radius of the semicircular groove on the front and back sides of the danage is slightly larger than the radius of the welding wire spool, but the welding wire spool inserted therein has approximately half of it as shown in FIG. Project upward from the groove. The protruding portion fits into a groove opened on the back surface of the danage above it (FIG. 2).

Therefore, every time one dunnage is laminated, the welding wire spout is formed in the groove opened on the surface with 8 pieces / 1 groove.
1 and 2, a plurality of dunnages are stacked in order from the bottom as shown in FIGS. 1 and 2, and the pallet 1 under the pile is lifted by, for example, a forklift. When the transfer is carried out with the welding wire spool housed in the cylindrical inner space, the space between the two vertically adjacent danages is relatively locked, and the direction perpendicular to the paper surface (side 5) in FIG. Longitudinal direction)
Needless to say, side slip (relative displacement in the horizontal direction) does not occur in the left-right direction (longitudinal direction of the side 6) in FIG. The transfer operator need only take care so that the piles (2a to 2f) do not skid on the pallet 1.

FIG. 5 shows an outline of the equipment structure for packing the welding wire spool shown in FIG. Welding wire spout
The end of the conveyor 12 for carrying out the spool 9, the spool loading robot 13, the pallet magazine 1 with the unloading mechanism
4 and a danage magazine 15 with a carry-out mechanism. In addition, there is a shrink winding machine 16 for preventing collapse of the load in the middle of the transportation of the transport conveyor 11.

The welding wire spool packing shown in FIG. 1 is performed by the sequence control of the controller of the control panel (not shown). In this case, first, the pallet magazine 14 feeds out one pallet 1 and places it on the starting end of the conveyor 11. Next, the danage magazine 15 places one danage 2a on the pallet 1 on the conveyor 11. Then, the robot 13 sequentially welds the welding wire spool 9 sent from the conveyor 12 every time the welding wire spool 9 arrives, in a groove opened on the surface of the dunnage 2a, side by side in the direction in which the groove extends, and around the spool peripheral surface. Insert down (flange vertical). When the insertion of two rows (2 × 8 pieces) is completed, the danage magazine 15 places one danage (2b) on the danage (2a) on the pallet 1. The danage magazine 15 has the same structure as that shown in FIG. 2 (however, a welding wire spool, a pallet, a synthetic resin coating 10).
Etc.) Many dunnages are stacked one above the other so as to form a cylindrical space between them, so that the dunnage magazine 15 loads one dunnage (2b) into the dunnage (2a) on the pallet 1. When placed on top, the stacking shown in FIG. 2 will be performed. When the danage magazine 15 completes loading a predetermined number (6 in the example shown in FIG. 2) of danage, the conveyor 11 is driven out, and the pallet 1 (and the 6 danages 2a to 2f on it) are moved. When it reaches the shrink winder 16, it stops. When there is this stop, the shrink winding machine 16 winds the heat-shrinkable synthetic resin sheet around the pallet 1 and the four side surfaces of the six danridges 2a to 2f on the pallet 1 in a headband shape to start and end the sheet. Is fixed and heated. When such shrink winding is completed, the transport conveyor 11 is driven out. When the shrink-wrapped pallet 1 (and the six dunnages 2a to 2f on it) have been carried out to the predetermined position, the conveyor 11 stops, and the pallet magazine 14 delivers one pallet 1 to transfer the conveyor 11. Place at the beginning.
The following is similar to the above.

The robot 13 inserts a supporting rod into the inner space of the cylindrical body (body) at the center of the welding wire spool 9, lifts it, and determines the number of danages loaded on the pallet 1 and the uppermost danage. It is transferred to a three-dimensional position (position in the carry-out direction of the conveyor 11, horizontal position and height orthogonal thereto) defined by the number of welding wire spools already mounted. In this example, since the central axis of the welding wire spool 9 (the winding center line of the welding wire) is parallel to the conveying direction of the conveyor 11, the side 5 of the danage in the danage magazine 15 and the conveying conveyor 11 is the conveyor 11. It is parallel to the conveyance direction of. Therefore, it is not necessary to change the position of the welding wire spool 9.
In the direction orthogonal to the groove of the danage (longitudinal axis direction of the side 6), even if the positioning of the welding wire spool 9 with respect to the groove of the danage is rough, the spool 9 is formed along the arc-shaped inner wall surface of the groove.
Since the spool 9 automatically moves to the bottom of the groove, that is, the center of the groove, accurate positioning by the robot 13 is unnecessary. Nevertheless, the spool 9 is accurately positioned at the groove center.

[0016]

EFFECT OF THE INVENTION Since the welding wire spool may be loaded side by side in the groove opened in the surface of the spool support with the flange vertical, the loading of the spool is easy and Accurate positioning of the spool.

Within the pile of supports on the pallet, there are a plurality of columnar rows of welding wire spools horizontally arranged at a predetermined pitch, and each row of rows has a lower spool. It is located in a cylindrical space between the support (first support) and the upper spool support (second support). In the direction in which the rows are arranged side by side and in the horizontal direction orthogonal to it,
Since the welding wire spool is an interposing body that connects the lower spool support and the upper spool support, the lower spool support and the upper spool support are provided. Is less likely to cause relative positional deviation in the horizontal direction.
The piles of the supporting body are less likely to lose loads.
