Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding material for a band-shaped material on a winding frame or a spool, and more particularly to a support shaft for supporting and fixing a magnetic tape winding body.

Magnetic tape windings or other thin strips of material are transported, transported and processed exclusively by special equipment. Such a tape-shaped or strip-shaped material winding body is wound around a spool or a winding frame, and is transported while being suspended by a transporting device with a central groove cavity passing through a support shaft.

In order to facilitate the processing of the individual tape windings in the recording device and to prevent the generation of packaging waste, the transport device can be moved to the recording device. Then, in order to prevent the plurality of winding bodies from contacting and rubbing without using a partition, each winding body must be firmly held and fixed in the conveying device.

[0004]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to support a winding body so that the winding body can be easily fixed and transported without damage.
The purpose of this is to provide a supporting shaft to be fixed.

[Means for Solving the Problems] However, the above-mentioned problems are
A support shaft for supporting and fixing a strip of material on a winding frame or spool, the support shaft being at least partly configured as a hollow shaft and at least one chuck near its end. A part is formed, the chuck part being connected to a longitudinal moving member in the hollow shaft, the moving member being made up of two parts, one part of which is positionally immovable and the other part of which is Is at least 1
A plurality of chuck portions, each of which is movably configured, is provided with a device for moving a longitudinal movement member, and wherein the chuck portions are released and actuated for extension. It was found to be solved by a support shaft that

As a result, the individual tape winding bodies can be pressed very strongly in the longitudinal direction of the shaft, so that the contact friction between the winding bodies is sufficiently prevented and avoided over a long path during transport. obtain. In a practical configuration, the support shaft is a hollow shaft provided with a member which can be elongated in the longitudinal direction by the introduction of a pressure medium. The longitudinally extensible member may also consist of a threaded bolt and a device for extending it.

In a further preferred embodiment, at least 1
In the rest position, the chuck portion fits in the recess of the longitudinal moving member and is aligned with the outer peripheral surface of the hollow shaft even if the outer shape of the chuck portion is the highest. This allows the wound body to move longitudinally along a support shaft that passes through the central groove cavity.

In yet another advantageous embodiment,
The elongate member of the longitudinal movement member extends longitudinally, causing the chuck portion to escape from the recess and be moved parallel to the support axis and thus toward the shaft end.

By actuating the extension device, the movable part of the longitudinal movement member is moved in the support axis direction,
This causes the chuck portion to escape from the recess and move in parallel to the support shaft toward the support shaft end portion, whereby the chuck portion projects beyond the outer periphery of the hollow shaft.

Preferably, the extendable member is constructed as a pneumatically extendable flexible member so that the extension operation can be performed simply and reliably.

Furthermore, the longitudinal displacement member is preferably configured as a hollow member operatively associated with at least one chuck portion. The extendable member is advantageously configured as a flexible bellows member having at least one bendable portion.

It is also preferable that the longitudinal moving member is composed of two parts, the first part has at least one chuck part, and the second part has a recess into which the chuck part fits. First of this longitudinal movement member
Suitably, an extendable member is provided between the portion and the second portion.

It is preferred that the longitudinal displacement member, especially in its intermediate zone, be provided with an entry / exitable projection for restraining the radial displacement of the spool or the bobbin.

Also, a screw bolt having an outer peripheral thread engraved,
Correspondingly, it is preferable to provide a longitudinal moving member having a chuck portion having an inner peripheral surface screw thread.

It is also preferable that the extension device is a rotary crank provided on the end wall, which can be folded and stored in the recess of the longitudinal moving member. This makes the operation of the support shaft extremely easy and reduces the protruding portion.

[0016]

The present invention will be described in more detail below with reference to the accompanying drawings which exemplarily show embodiments according to the present invention.

The winding body conveying device 5 essentially comprises a frame body 6, a support shaft 7 rotatably mounted on the frame body 6, a tape winding body 8 supported by the frame body 6, and several tape winding bodies ( The free end of the support shaft 7 is indicated by 9.

In the sectional view shown in the upper part of FIG. 2, the support shaft 7'is shown in the rest state in the upper half of the center line M and the support shaft 7 "is in the activated state in the lower half thereof. There is.

In each case, the support shaft 7 comprises a hollow shaft 10 having a longitudinal movement member 11 therein, which longitudinal movement member 11 has an outer portion 11A having a chuck portion 12 at its free end. And an inner portion 11B. The support shaft 7 further has a bellows-shaped member 13, and a bendable portion 14 is formed on the inner surface thereof. One end of the longitudinal movement member 11 is pressed and supported by the spring 15 against the support plate member 16 of the winding body transporting device 5, and the other end thereof is a pressure medium in the flexible bellows member 13. It has a valve 17 for pressurizing air (arrow P). Further, a valve 18 for discharging the compressed air is provided,
It is also possible to use a pressure medium press-in / exhaust valve instead of the press-in valve 17, in which case the exhaust valve 1
8 is omitted.

The operation of the winding body supporting shaft 7 of the present invention in the above-described winding body conveying device 5 will be described below.

Above the center line M, the hollow shaft 1
0, and thus also the bellows member 13 is shown in its rest position, its bendable portion 14 being in a bent state, as is apparent. In this rest position,
A chuck portion 12 having a shape suitable for the recessed portion 19 formed in the inner portion 11B of the longitudinal moving member 11 is fitted therein. Diameter DO of this chuck portion 12
Is equal to or slightly smaller than the diameter D of the hollow shaft 7, so that the spool 20 (winding frame) (only part of which is shown) slides on the support shaft 7 in the direction C. , You can move. This is because the spool inner diameter d is slightly larger than the support shaft outer diameter. A winding body 21 is schematically shown on the spool 20.

In the upper part (a) of FIG. 2, below the center line M, the chuck portion 12 has an inclined surface 22 of the concave portion 19.
It is shown partially escaped from. In this case, that is, the diameter DA of the chuck portion 12 at the time of expansion is
It is enlarged from its diameter DO at rest and from the diameter D of the hollow shaft 7 and is therefore in the restrained condition of the spool or the winding body. This pressurizes a pressure medium, for example air, from the valve 17, which spreads the bellows-like member 13 and resists the force of the rib 15 to move the moving member 11 in the support shaft 7 to the left in the drawing (arrow A). It is realized by moving. This causes the outer part 11A and thus the chuck part 12
Partly escapes from the concave portion 19 and causes an increase in the chuck part diameter (DA> DO), resulting in a wound body restrained state. Free end of support shaft indicated by broken line 23 (FIG. 1)
As a result, the upper spool 20 and the tape winding body 21 are
Also, under the pressure of conventional means not shown, the outer part 1
It is constrained on the support shaft 7 regardless of the longitudinal movement of 1A.

The longitudinal moving member 11 is further denoted by reference numeral 2.
There is provided a single or multiple radial projections, indicated at 5, which are for example a fixed fit in the recess 26 of the inner part 11B. Due to the disengagement movement of the chuck portion 12, this projection 25 fits into the inner diameter portion of the spool 20 via the hole 27 of the hollow shaft 10 to reduce or avoid radial movement of the spool during its transport. Recess 2
6 and the pores 27 are formed in a slit shape or a similar shape. In some cases, the protrusion 25 alone may be sufficient for restraining the spool or the winding body.

In order to enable more sufficient pressure restraint, the width of the chuck portion 12 is made narrower than that shown in the lower end view of FIG. 2, and the inside of the slit formed in the outer jacket of the hollow shaft 10 is made smaller. You need to be able to exercise enough.

As shown in the lower end view of FIG. 2, one of the hollow shafts 10 is arranged so that after the pressure medium has been discharged from the valve 18, the spool or winding body can be manually removed at the inner peripheral edge of the internal bore of the spool. A recessed portion 24 is provided on the surface.

The bellows-like member 13 is made of a flexible material so that it can be stretched by being stretched (see the bendable portion 14). As this material, materials having different expansion coefficients can be used. Rubber elastic materials for extendable bodies can also be used. As a material for the longitudinal moving member 11, a thermoplastic injection-moldable synthetic resin is suitable.

The pressure medium, for example air, is pressed in via a valve 17 from an air compressor or a simple air pump or compressed air cylinder.

In the other embodiment shown in FIG. 3, similarly, with the center line M as a boundary, the support shaft 28 'in a resting state is moved upward.
The support shaft 28 "in the extended state is shown below.

In any case, the support shaft 28 is the hollow shaft 2
9 is composed of a movable part 30A having a chuck part 12 and a stationary part 30B which is fixed in position.
And the immovable portion 30B includes a screw bolt 3
1, an end wall 32 screwed to this, and a turning crank 33 are mounted. An outer peripheral surface screw 34 is engraved on the free end portion of the screw bolt 31 and an inner peripheral surface screw 35 corresponding thereto is engraved on the movable portion 30A, and they are engaged with each other.

The rotary crank 33 above the center line M
Is rotated in a rest state in which the chuck portion 12 is engaged with the recessed portion 19, the chuck portion 12 partially escapes from the recessed portion 19, and the protrusion 25 (the lower portion b in FIG. 3 and the upper portion in FIG. 2). The outer diameter of the support shaft 28 is increased (see D.a) (from D to AD).
Above (a)). As shown in the upper part (a) and the lower part (b) of FIG. 3, the rotary crank 33 is brought from the operating position shown by the solid line to the folded position shown by the broken line, the protruding part being especially for mounting the winding body. , It is stored so that it does not get in the way when it is removed.

The support shaft for supporting the strip-shaped or tape-shaped winding body wound on the spool essentially comprises a member or screw bolt which is extendable in the longitudinal direction, a chuck portion and optionally a restraining projection. A longitudinally moving portion having a chucking portion and optionally a restraining projection, which is indirectly movable in an extending direction to an extending or restraining position via an extendable member or screw bolt. The extension of the extension member is preferably performed with air as the pressure medium. The screw bolt operation is easy to perform by hand.
