Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a shaft for a container for housing a long tape winding body, the shaft supporting the winding body.

Conventional technology Conventionally, in a manufacturing factory, magnetic tape is simply cut into product widths from a raw material, wound in a long state, wound around a hub, moved to a recording factory, put in a duplicator, and recorded from a master tape. It is recorded, moved to a built-in factory, cut into pieces as a finished product, and assembled in a cassette case. In this way, the magnetic tape is handled as it is, and is transported, moved, stored, recorded, etc. until it is cut to the final length. The long tape roll is usually called a pancake. When transporting or moving the product, naturally store it in a case to protect it from external forces and dust.

A container that can accommodate a large number of long tape winding bodies at one time is suitable for this type of case. Especially, with a caster and a plurality of shafts supporting a number of laminated long tape windings protruding from the inner surface of the rear plate corresponding to the front lid, the container can be freely positioned as needed. Since it can be moved up to, and the front lid can be opened to remove the fixture, and the long tape winding body can be removed from the shaft by pulling it out, no special unpacking work is required, which is preferable. Also, when storing, hold a long tape winding body for each shaft,
A shaft is inserted through the hub hole, and an appropriate number of shafts are sequentially fitted, and then fixed with a fixture to support the shaft, and the front lid is closed. These shafts each have an elongated base portion which protrudes upward at both side edge portions which come into contact with the inner surface of the hub of the long tape winding body and which has a required working space between the both edge portions. Moreover, the cross-sectional shape perpendicular to the longitudinal direction is V-shaped, which is symmetrical. This shape emphasizes workability such as attachment to and detachment from the shaft, and there is usually a play space between the base and the hub.

However, since the recording and recording factories are concentrated in the Kanto region, transportation of such a long tape winding body is transported from the manufacturing plant to the embedded plant. Domestic transportation is mainly used. Therefore, it is necessary to consider not only the stability during transportation but also the workability especially during storage and removal.
As shown in FIG. 6, the V-shaped type has both edges 12 of the shaft 10,
Since only 14 is in contact with the hub 16 and there is play below, the workability is good, but the long tape winding body 18 rattles during transportation and the stability is poor. Moreover, if the rattling is large and severe, steps and shavings are likely to be generated due to the interlayer displacement of the wound long tape.

The present invention has been made by paying attention to such a conventional problem, and can stably support a long tape winding body during transportation, and can be quickly attached and detached at the time of storing and taking out. An object of the present invention is to provide an excellent shaft for a container for storing a long tape winding body.

Means for Solving the Problems Means for achieving the above object will be described below with reference to FIGS. 1, 4, and 5 corresponding to the embodiments.

Shaft 20 for this long tape roll storage container
The two side edges 36, 38 that contact the inner surface of the hub 60 of the long tape winding body 52 are respectively projected upward, and a working space S2 is provided between the both edges, and the working space S2 is provided between itself and the hub 60. Is a play space
It is composed of an elongated base portion 40 having S1, and its cross-sectional shape perpendicular to the longitudinal direction is bilaterally symmetric. Then, the cross-sectional shapes of both side edge portions 36, 38 are respectively made linear, the intersection angle θ of the extension lines thereof is set to 120 °, and both edges thereof are positions to be fitted into the grooves 64, 66 on the inner surface of the hub. .

Further, the cross-sectional shape of each of the side edge portions 76 and 78 is a partial arc shape that substantially matches the inner circumference of the hub 74, and the base portion is substantially V-shaped.

Operation With the above configuration, the side edges 36, 38 project from the base 40 such that their extension lines intersect 120 °, so that a large number of long tape winding bodies 52 in which the shaft 34 is laminated are formed.
When supporting, the weights of the wound bodies 52 are divided into two equal parts and added to both edges contacting the inner surface of the hub 60, and are combined to act on the base portion 40. Therefore, the long tape winding body 52
Is well-balanced during transportation and stable without rattling. Moreover, by inserting both edges into the grooves 64, 66 on the inner surface of the hub, rattling is further eliminated and stability is achieved. At the time of installation and removal, the distance between both edges is slightly smaller than the diameter of the hub hole 62, so if there is a play space S1 in the protruding direction of the base 40,
It is possible to easily fit or remove the long tape winding body 52 by slightly lifting it.

Also, if the cross-sectional shapes of both side edge portions 76 and 78 are made into a partial arc shape that substantially matches the inner circumference of the hub 74, the curvature of the arc will be
In order to approach the curvature of 74, the hubs 74 of the long tape winding body 72 come into contact with their arcuate outer surfaces over a wide range to some extent,
Well supported and stable without rattling. Moreover, about V
Since there is a play space S4 between the character-shaped base portion 80 and the hub 74, workability is good.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a long tape winding storage container to which the present invention is applied. In the figure, 20 is a container, 22 is a front cover widely covering the front side, 24 is a rear plate, 2
6 and 28 are upper and lower plates, and 30 and 32 are left and right side plates. 6 of these
Among the surfaces, transparent members such as vinyl and acrylic are used for the front lid 22 and the left and right side plates 30, 32 so that the inside can be seen through. However, considering the mechanical strength of the rear plate 24 and the upper and lower plates 26, 28,
Use plywood. This front lid 22 has magic bands on four sides. Therefore, it is possible to satisfactorily close the inside so that dust does not enter, and it is possible to appropriately open the whole area on the front side or to open only a part thereof. A plurality of metal shafts 34, for example, six metal shafts 34 are provided on the rear plate 24 vertically from the inner surface thereof in the direction of the front lid 22 and vertically and horizontally at substantially equal distances. For this reason, the rear plate 24 has a double structure composed of inner and outer flat plates to particularly increase the mechanical strength and firmly hold the root of each shaft 34. Each of these shafts 34 has both side edge portions 36 and 38 which come into contact with the inner surface of the hub of the long tape winding body, and which has a working space for inserting a hand or the like between the both edges. It is composed of an elongated base portion 40 having a play space between itself and the hub, and its cross-sectional shape perpendicular to the longitudinal direction is bilaterally symmetrical, and has the features described later. 42 is the base
It is a screw hole for receiving the hub fixing screw at the tip of 40. The left and right side plates 30 and 32 are provided with operation handle installation parts 44 and 46, respectively. One operation handle installation part 44 is provided near the center of the left side plate 30 for lifting the container, and the other operation handle installation part 46 is provided near the upper side of the right side plate 32 for pushing and pulling. Further, the bottom plate 28 has casters 48 at the four corners of the bottom surface, respectively.
Is installed.

In such a container 20, the long tape winding body is stored according to the following procedure. First, the front lid 22 is opened to widen the entire front side. Next, the cardboard spacer 50, the long tape winding body 52, 20 reels, the hub fixing plate 54, and the hub fixing screw 56 are attached to the shaft 34 in this order according to the arrangement shown in FIG. At that time, the hub fixing screw 56 is screwed to the tip of the shaft 34 with the hub fixing plate 54 interposed.
The long tape winding body 52 of the reel has a spacer 50 arranged on the inner side and is laminated, and is fixed and supported by the shaft 34. In addition,
Spacer 50 also on the front side of the laminated long tape winding body 52
Is preferably arranged. Therefore, a film-like dust prevention cover is wrapped around the laminated long tape winding body 52, and the seam is fixed with cellophane tape. Each other shaft
Similarly, the laminated long tape winding body 52 and the like are attached to 34, and then the front lid 22 is closed. Then, transportation or the like becomes possible.

FIG. 3 is a perspective view showing a state where six groups of 20 reel long tape winding bodies 52 stacked in the container 20 are stored. Incidentally, 58 is a dust prevention cover. The cross-sectional shape of these long tape winding bodies 52 and the like, which is perpendicular to the longitudinal direction of the shaft 34, is symmetrical as shown in FIG. That is,
The both side edges 36, 38 of the shaft 34 are straight lines with the extension lines intersecting each other at an intersection angle θ of 120 °, and a U-shaped base 40 projects in a direction that bisects the angle. When the side edges 36, 38 of the shaft 34 and the base 40 are made to differ by 120 ° and are projected in this manner, the circle is divided into three equal parts, so that the long tape winding body 52 of 20 reels in which the shaft 34 is laminated is formed. When supporting
The weight of the wound body 52, for example 40 kg, is divided into two equal parts (tips) contacting each other at a position 120 ° apart from the inner surface of the hub 60 along the inner circumference thereof, and 20 kg each is added to each edge to be synthesized. Acting in the protruding direction of the base 40. Therefore, the long tape winding body 52 is supported in a good balance during transportation and is stable without being stiffened. At that time, on the inner surface of the hub 60, along the circumference
Grooves 64, 66, 68 that extend in the longitudinal direction of the shaft 34 every 120 °
By disposing, the long tape winding body 52 is formed by inserting both edges of the shaft 34 into those grooves, for example, 64, 66.
It is stable and stable. As a result, it becomes difficult for the long tape to be prevented from being stepped off or shavings due to the interlayer displacement. By the way, if dust adheres to the surface of the magnetic tape, a signal error occurs, and if the data is hide data, the image is disturbed, and if it is an audio tape, it causes skipping and noise is also generated.

When installing or removing, the distance between both edges is 62
Since there is a play space S1 between the base 40 and the hub 60 in the projecting direction of the base 40, the work space S2 between the two edges is used and the long tape winding body 52 is The shaft 34 can be easily fitted or removed with a little extra lifting.

FIG. 5 is a sectional view similar to FIG. 4 of another long tape storage container shaft to which the present invention is applied.
In the figure, 70 is the same as in the above-mentioned embodiment, and both side edge portions 76 and 78 which come into contact with the inner surface of the hub 74 of the long tape winding body 72 are respectively projected upward, and a working space S3 is provided between the both edges. It is a shaft which is provided with an elongated base portion 80 having a play space S4 between itself and the hub 74, and whose cross-sectional shape perpendicular to the longitudinal direction thereof is symmetrical. However, both edge portions 76 and 78 are respectively the hub 74
It has a partial arc shape that roughly matches the inner circumference of the. Therefore, the curvature of the arc will approach that of the hub 74,
The long tape winding body 72 contacts the arc-shaped outer surfaces over a wide range to some extent, is well supported, and is stable without rattling. In addition, if the base 80 is formed of orthogonal members in a substantially V shape and the play space S4 with the hub 74 is provided, workability is improved. The workability is improved by polishing the outward facing surfaces of the side edge portions 76, 78.

Effect of the Invention According to the present invention described above, since both side edge portions of the shaft project from the base portion such that their extension lines intersect 120 °, the long tape winding body is supported in a well-balanced manner. Stable without rattling. Moreover, since both edges of the shaft are fitted in the grooves on the inner surface of the hub, the shaft is stable without rattling. Therefore, it is unlikely that step drops or shavings will be generated due to the gap between the layers of the long tape. If the distance between both edges is appropriately made smaller than the diameter of the hub hole and a play space is provided between the base portion and the hub, the workability is naturally improved.

Further, if both side edges of the shaft are formed in a partial arc shape that substantially coincides with the inner circumference of the hub, the long tape winding body comes into contact with the arc-shaped outer surfaces over a wide range to some extent, and thus is well supported. It stabilizes without rattling. Moreover, the distance between the bases of both side edges is appropriately made smaller than the diameter of the hub hole, and
If a play space is provided between the character-shaped base and the hub, the workability is naturally improved.
