The small-wound member is constructed by winding a member in a cylindrical shape around a shaft, and the shaft has a core hole with a square cross section. The small roll member is passed through a horizontal round bar provided in a box-shaped storage stand in the core hole of the shaft, and is stored in a predetermined storage location. When a small roll member is assembled into a member supply machine, the cylindrical small roll member has a weight of approximately 500 kg, so it is first lifted up via a hoist attached to the hook of an overhead mobile crane, and then , and is extracted from the round bar of the storage stand and transported along the rails of the overhead moving crane to the feeder. The core hole of the shaft of the small roll member fits into the square cross-section shaft of the feeder (which has a brake and is difficult to rotate), so the hanging device on the crane can be adjusted up and down while the small roll member is suspended. Ru. At a position where the tip of the shaft and the core hole of the shaft can fit together, the small roll member is pushed into the shaft and assembled into the feeder.

Therefore, there is a problem in that a space is required for transporting equipment such as the overhead moving crane and the rails and lifting equipment for the overhead moving crane. Also, the weight
The problem is that transporting a 500Kg heavy load with a crane involves dangerous work. There are also problems in that it takes time to align the tip of the shaft with the core hole of the shaft of the small winding member, requires skill and considerable effort on the part of the operator, and is also dangerous. Therefore, there is a problem in that it takes a considerable amount of time to replace the small roll member, such as installing and removing it, and the work efficiency is low.

(Purpose of the invention) Therefore, the present invention eliminates the danger of replacing small roll members, shortens the time for replacement work, eliminates the need for skilled work, and eliminates the need for equipment such as a crane and transportation space. The aim is to improve work efficiency and significantly increase productivity.

One end of the support beam 5 is supported by a fixed column 8 fixed to the base 7, and one end of the hanging scroll 6 is rotatably supported by the support beam 5 so that the hanging scrolls 6 are separated from each other by a distance _W0 . ing. When the small roll member 2 is supplied from the cart 1 to the feeder 4, the small roll member 2 is hung on and supported by the hanging scroll 6 so that the hanging scroll 6 passes through the core hole 3a. It can be supported by multiplying by 2.

Here, the feeder 4 is provided with a brake 9, and the brake 9 brakes the rotation of the hanging shaft 6 of the feeder 4.

The truck 1 also includes a pair of first columns 10, a pair of second columns 11, a plurality of upper beams 12, a plurality of lower beams 13,
It has a support rod 14, an auxiliary column 15, and a plurality of casters 16. The first columns 10 are spaced apart from each other and extend in the vertical direction, and the second columns 11 are spaced apart from each other and extend in the vertical direction.
It is facing 0. The upper beam 12 and the lower beam 13 connect the upper ends and lower ends of the first pillar 10 and the second pillar 11 that are adjacent to each other. The support rod 14 protrudes horizontally in the direction of the first support column 10 at approximately the center of the pair of second support columns 11, and one end of the support rod 14 is connected to the upper beam 12 and the lower beam 13 that connect the pair of second support columns 11 to each other. It is supported by an auxiliary column 15 supported by. The support rod 14 is inserted so that the support rod 14 passes through the core hole 3a of the small winding member 2.

At least one of the casters 16 is provided with a foot brake 1 that allows the trolley 1 to be fixed relative to the base 7.
6a is attached.

On the other hand, the pair of first columns 10 are connected to each other only by the lower beam 13, and no beam is provided to connect the upper ends of the first columns 10 to each other. Therefore, the upper plane surrounded by the upper beam 12 and the first support 10 and the first
The lower plane surrounded by the lower beams 13 connecting the columns 10 is continuously open without being obstructed by members such as beams.

Further, the upper ends of the first support 10 and the second support 11 project upward from the upper beam 12, and the lower ends project downward from the lower beam 13. The total dimension of the protrusion of these upper and lower ends from the upper beam 12 and the lower beam 13 is set to be smaller than the protrusion of the caster 16 from the lower beam 13.
However, the protrusion dimension of the lower end is naturally smaller than the protrusion dimension of the caster 16. Therefore, the first pillar 1
At least one of the upper and lower ends of the 0 and second support columns 11 protrudes upward or downward from the upper beam 12 or the lower beam 13 by a predetermined amount.

Further, the upper end surfaces 10a and 11a of the first support 10 and the second support 11 are concave, and the lower end surface 1 is concave.
0b and 11b are the upper end surfaces 10a and 11a, respectively.
It consists of a convex surface that can be engaged with. Therefore, the upper end surfaces 10a, 11a and the lower end surfaces 10b, 1 of the first support 10 and the second support 11, respectively.
One side of 1b is a convex surface, and the other side is a concave surface that can be engaged with the convex surface. The width W ₁ of the first support 10 of the truck 1 in the separation direction is smaller than the separation _{distance W 0 of} the hanging scroll 6 described above.

On the other hand, the hanging shaft 6 of the feeder 4 projects horizontally from the support beam 5 at the same horizontal level as the support rod 14 of the trolley 1, and the hanging shaft 6 has a round bar portion 6a on the side in the projecting direction.
and a square bar portion 6b on the support beam 5 side. The cross section of the round bar portion 6a is circular, and its tip is semispherical. The cross-sectional shape of the square rod portion 6b is the same as that of the small-volume member 2.
It has a square shape that almost matches the cross-sectional shape of the core hole 3a, and can be engaged with the core hole 3a through the round bar portion 6a. Therefore, the square rod portion 6b has the core hole 3a.
When engaged, the small winding member 2 and hanging scroll 6 can be prevented from rotating relative to each other. Also,
A fixed beam 17 is provided above the support beam 5 and extends in the horizontal direction, and one end of the fixed beam 17 is fixed to the fixed column 8. The fixed beam 17 and the support beam 5 are connected by an auxiliary beam 18,
A winding shaft 19 is attached to the auxiliary beam 18. The winding shaft 19 winds up the liner 2b in conjunction with the unwinding of the member 2a of the small winding member 2, and the unwound member 2a is guided by a guide 20 when being supplied to the next process.

(effect) Next, the effect will be explained.

First, at a storage location for the small roll member 2, the small roll member 2 is stored while being supported by the cart 1. At this time, on the first support 10 and the second support 11,
Since the lower end portions protrude upward and downward from the upper beam 12 and the lower beam 13, when the carts 1 are stacked with the respective supports aligned, the casters 16 will not ride on the upper beam 12. Therefore, it becomes possible to stack the carts 1 and store them, and the storage space is reduced. Also, the first support 10 and the second support of the trolley 1 are
Since the struts 11 are formed with concave upper end surfaces 10a, 11a and convex lower end surfaces 10b, 11b, when the carts 1 are stacked, displacement of the carts 1 is prevented and safety is improved.

Next, when transporting the small roll member 2, the trolley 1
is the foot brake 1 of the caster 16 by the operator.
When 6a is released, the worker carries it from the storage location to the front of the feeder 4, that is, the surface from which the hanging scroll 6 protrudes. At this time, the small roll member 2 weighs approximately 500 kg.
Although it is a heavy item, there are casters 1 on trolley 1.
6 is provided, the small roll member 2 can be easily and simply transported by hand together with the trolley 1. Therefore, large-scale equipment such as a forklift or an overhead crane is not required, and there is no dangerous work.

Next, on the front side of the feeder 4, the cart 1 is arranged so that the support rod 14 of the cart 1 faces the hanging shaft 6 of the feeding device 4, and furthermore, the tips of the support rod 14 and the hanging rod 6 are arranged close to each other. The position of the truck 1 is finely adjusted, and the foot brake 16 of the caster 16 is
a is locked. At this time, the casters 16 facilitate positioning of the cart 1 and the feeder 4, and the foot brake 16a securely fixes the cart 1 to the base 7.

Next, the operator moves the small roll member 2 to the vicinity of the square bar part 6b of the hanging scroll 6 while sliding it on the support rod 14 so as to make it follow the round bar part 6a of the hanging scroll 6. Next, the small winding member 2 is slightly rotated so that the core hole 3a of the small winding member 2 and the square bar part 6b are engaged, and then the small winding member 2 is further engaged with the square bar part 6b and the corner bar part 6b is engaged with the small winding member 2. When inserted all the way into the rod part 6b,
The small roll member 2 is supplied from the cart 1 to the feeder 4 and supported by the feeder 4. At this time, since there is no beam connecting the upper ends of the first pillars 10, it is easy for the operator to move the small roll member 2 and align the core hole 3a and the square bar part 6b, and the small roll member 2 can be moved easily by the operator. The operation of feeding food from the trolley 1 to the feeder 4 is extremely simple and does not require much effort.

Next, the member 2a of the small roll member 2 is unwound through the guide 20 and conveyed to the next process, and the liner 2b is taken up on the take-up shaft 19 in conjunction. At this time, the rotation of the hanging scroll 6 is controlled by a brake 9 as necessary.
Since the brake is applied, work efficiency is improved.

Furthermore, since the width W ₁ of the cart 1 is smaller than the separation distance W ₀ between the hanging scrolls 6, four carts 1 are arranged in front of the feeder 4 as shown in FIG. It becomes possible to carry out replacement work, and in addition,
The present invention can also be applied to high production efficiency equipment that automatically performs this rehanging work all at once.

(Effects) As explained above, according to the present invention, it is possible to reduce the storage space for the small roll member and to improve the safety at the storage location.

Further, the work of transporting and supplying the small roll member can be made simple and easy, and large amounts of labor and skill can be made unnecessary. At the same time, it is possible to eliminate the need for equipment such as a forklift, an overhead moving crane, and a hanging device, as well as transportation space, and it is possible to significantly improve equipment efficiency.

Further, it is possible to improve the work efficiency of unwinding the member wound into a small roll member from the supply machine.
