DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet-like film used for packaging, for example, coffee beans or the like in a predetermined amount, the film being wound in a coil state and carried in. More specifically, the present invention relates to a portable coil stocker which can be transported by arranging a plurality of receiving bases for receiving coils in parallel with each other when transporting to a position where the sheet is to be rewound.

[0002]

2. Description of the Related Art Conventionally, a coil used to wind a sheet-like film has been formed into a relatively light-weight and small-diameter coil so that it can be handled and manipulated artificially. Since the time required for rewinding to a sheet-like material for use in packaging work is too short, this has increased the number of times of transfer work to the film supply table for rewinding the coil. There was an inefficient aspect. Therefore, from the viewpoint of improving the workability by reducing the number of times of transfer, the length of the film is made longer by increasing the coil diameter.

[0003]

In this case, the conventional small-diameter coil allows an artificial transfer operation, but
By increasing the coil diameter for the reasons described above,
The coil weight exceeds the artificial lifting force,
Some kind of mechanization was needed. Since the three coils 1 are brought into the rack 7 with the axes X aligned with each other as shown in FIG. As shown in FIG. 5, in the work for removing the coil 1 from the rack 7 and transferring it to the film supply table 6, the work of separating the coil 1 one by one and the work of replacing the coil 1 are necessary, and providing permanent equipment such as an overhead crane is required. Was also considered. However, there is an aspect that such a permanent installation is difficult to adopt because the apparatus becomes large in size. An object of the present invention is to provide a coil stocker or the like in which a coil is placed all over in a work flow for removing from a rack and replacing the film supply table.
It is an object of the present invention to provide a portable coil stocker that can improve work efficiency while minimizing equipment reinforcement.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A structure for supplying a packaging film (an example of a thin material) to a Bosch packaging machine will be described. As shown in FIG. 4,
The coil 1 of three turns is taken out by the coil stocker 3 provided with the three receiving stands 2, the coil stocker 3 is placed at a predetermined position, and the coil 1 placed on the receiving stand 2 of the coil stocker 3 is removed. Then, the coil 1 is lifted by the power lift 5 with the shaft 4 inserted through the shaft 4 and placed on the film supply table 6 to perform a preparation process for a packaging operation.

The coil 1 will be described. As shown in FIG. 1, the coil 1 is formed by winding a resin film for packaging a product to a diameter of 675 mm (or 660 mm) and a winding length of 2500 m.
Is formed on At the time of being transported to the cargo handling place of the factory, three rolls of 2500 m are bundled and attached to the rack 7 as shown in FIG. Rack 7
In this state, the three winding coils 1 are attached in close contact with their axes X aligned with each other.

The coil stocker 3 will be described. On the coil stocker 3, a receiving table 2 for receiving the three coils 1 is attached to the main body frame 8, and a sliding rail 9 is laid along the longitudinal direction of the main body frame 8. The sliding rail 9 and the slide body 10 that slides with respect to the sliding rail 9 constitute a mechanism A for moving the receiving table 2. The sliding rail 9 and the slide body 10 are, in principle, commercially available products (THK's L
M guide SR20W2UU + J2401L) is used. Of course, it may be manufactured exclusively. When the receiving table 2 is moved, the receiving table 2 can be pushed by the operator together with the coil 1. First, the receiving table 2 is moved to one end of the main body frame 8 to receive the group of coils 1 taken out from the rack 7.
The receiving table 2 is configured to be movable over a position a and a second position b where the individual receiving tables 2 are independently moved to the other end of the main body frame 8 and the coil 1 is taken out.

The receiving table 2 will be described. As shown in FIG. 1, a receiving surface 2 </ b> A for receiving the coil 1 is provided on the receiving table 2, and a V-shape that is recessed downward at an intermediate position on the receiving surface 2 </ b> A along the moving direction of the receiving table 2. The upper end 2a located on the first position side is positioned higher than the other upper end 2b located on the second position side at an inclination angle larger than the inclination degree of the V-shaped portion. Start-up is formed. Thus, what is formed in a V shape is
This is because the reaction force from the receiving surface 2A applied to the coil 1 can be dispersed as compared with the case where the coil 1 is mounted on a flat surface, so that the coil 1 itself is less deformed. Top 2
a and 2b are set in a rounded shape, and the coil 1
Is in contact with the upper ends 2a and 2b so as not to be damaged. The reason why the upper end 2a on the first position side is raised from the other upper end 2b is that, when the coil 1 is taken out from the rack 7, the receiving stand 2 and the coil 1 are connected to the main frame 8 by the claws 18A of the forklift 18. Is lifted in the inclined state, so that the load of the coil 1 moves rearward.

Further, since the upper end 2b is lower than the other upper end 2b, as shown in FIG.
When the coil stocker 3 is scooped by the receiving table 2, the receiving table 2 is easily inserted below the coil 1. The main body frame 8 is provided with an engaging portion 8A for inserting the claw 18A of the forklift 18 in order to lift the whole frame with the forklift 18 when the coil 1 is scooped from the rack 7 by the receiving table 2. . A slide 10 is attached to the bottom surface of the receiving table 2 at two positions in the moving direction of the receiving table 2, and the slide 10 is mounted on the sliding rail 9. Brackets 11 are provided on the front and rear surfaces of the receiving base 2, respectively, and receiving brackets 12 are fixedly provided at corresponding ends of the first position a and the second position b of the main body frame 8,
The receiving table 2 is moved to the second position b or the first position a, the bracket 11 and the receiving bracket 12 are vertically overlapped, and the movement is prevented by the stop pin 13. The bracket 11, the receiving bracket 12, and the stopper pin 13 are referred to as a stopper mechanism B. The stopper mechanism B only needs to be provided corresponding to at least the first position a.

As shown in FIG. 2, the slide body 10 is provided at the center of the bottom surface of the receiving table 2 in the left-right direction orthogonal to the moving direction. A body 14 is provided. That is, the slide body 1
Since the rail 9 is located at the left / right intermediate portion of the receiving base 2 corresponding to 0, the receiving base 2 may fall right and left when the receiving base 2 moves. In this case, it is necessary to provide a pair of right and left rails 9, but this is difficult to adopt in terms of manufacturing cost. Therefore, angle-shaped guides 14 are provided at the left and right ends of the bottom surface of the receiving table 2 so that there is a slight gap between the lower end of the guides 14 and the rail mounting surface during normal movement. When the receiving table 2 is tilted, the lower end of the guide body 14 is brought into contact with the rail mounting surface to prevent a large tilt from occurring and to continue the movement.

With the above arrangement, the handling of the coil 1 will be described again in detail. As shown in FIG. 4, the coil stocker 3 lifted and supported by the claws 18A of the forklift 18 as a transport device is inserted into the rack 7 with respect to the coil 1 attached to the rack 7 and carried into the cargo handling area. The coil 1 is lifted while placed on the receiving table 2, and the three coils 1 are removed from the rack 7 together with the coil stocker 3. The removed coil stocker 3 is transported to a later-described reel rewinding work site in the factory and is placed there. The operator pushes the coil 1 located at one end on the coil stocker 3 for each receiving table 1 in the mounted state to move the coil 1 from the first position a to the second position b, and the shaft 4 is moved into the moved coil 1. Make it ready for insertion. At this second position b, the receiving table 2 is fixed with a locking pin 13. On the other hand, the receiving table 2 supporting the two coils 1 left at the first position a is fixed in position by using a locking pin 13 in order to prevent rattling during transportation. The two coils 1 in the standby state have a V-shaped mounting surface on the receiving surface 2A on the receiving table 2 side, and thus prevent the coil 1 from being deformed as compared with a coil having a flat receiving surface 2A. Can be achieved. As shown in FIG. 5, the shaft 4 is inserted into the coil 1 extended to the second position b. Bearings 15 are externally fitted to both ends of the shaft 4 projecting from both side surfaces of the coil 1, and the bearings 15 are lifted by the power lift 5 to rewind the coil to be used in the next operation step. The film is attached to a film supply table 6 for supplying the film up to.

Another embodiment will be described below. [1] In the embodiment described above, in order to move the coil 1 to the second position b with the coil 1 placed on the receiving table 2, the direction perpendicular to the axis X of the coil 1, Although the mode of moving in the longitudinal direction is adopted, a configuration in which the receiving table 2 is moved along the axis X of the coil 1 as shown in FIG. 6 may be adopted. That is, a single sliding rail 9 is laid on the main body frame 8, the receiving base 2 is placed on the sliding rail 9, and the plurality of receiving bases 2 are arranged side by side along the longitudinal direction of the main body frame 8. Set up. And you may comprise so that a receiving stand may be moved to the state separated apart. The separation distance depends on the length of the shaft 4 inserted into the coil 1 (the configuration included in claim 1). [2] In the above-described embodiment, the coils 1 placed at the first position a for the subsequent process are moved by an interval sufficient to insert the shaft 4 and set at the second position b. In the above, the mode of sliding on the main body frame 8 has been described, but here, a mechanism A for moving in the vertical direction will be described. As shown in FIG.
At the first position of the main body frame 8, there are provided three receiving stands 2 for receiving the coil 1 taken out of the rack 7, and a receiving plate 2B for receiving the coil 1 and supporting the receiving plate 2B. The leg 2C is formed. As shown in FIG. 7, the left and right receiving tables 2 of the three receiving tables 2 are configured to be slidable up and down with respect to a holder 16 supporting the leg 2 </ b> C. Are supported in a fixed state that does not move up and down with respect to the holder 16. In the side receiving base 2, the springs 17A and 17B for urging the receiving plate 2B toward the first position for receiving the coil on the leg 2C are externally fitted. As a result, FIG.
As shown in (a), in a standby state in which the coil 1 is received, the respective receiving plate portions 2B are at the same height position. In this state, when the group of coils 1 is placed on each receiving plate portion 2B, the right and left receiving plate portions 2B are moved by springs 17A and
It descends against the urging force of 17B. As shown in FIG. 7B, since the urging force of the spring 17A is large in this case,
The left receiving plate 2B stops above the right receiving plate 2C. In this state, the stop positions of the coils 1 are inconsistent, and the axes X of the coils 1 do not match. Then, the receiving plate 2B and the leg 2
C, a notch 2d is formed in which only the end of the shaft 4 is located, and the shaft 4 is disposed on the side receiving base 2 with respect to the coil 1 as shown in the drawing. Can be penetrated. A configuration in which the coil 1 is moved from the upper first position to the lower second position by the above configuration is also referred to as a moving mechanism for the coil 1. [3] In the above-described transporting device 18, the forklift 18 is adopted as a device for transporting the coil stocker 3. Alternatively, an automatic guided vehicle may be used, or a roller conveyor or the like may be permanently installed as a fixed facility.
