Technical Field

The invention relates to a tape rewinder (tape changer, japanese: テープ reel き instead of え).

Background

Conventionally, the following devices have been disclosed: by rewinding the masking tape of the finished product (predetermined japanese) to the small-diameter tape core, a small-sized tape body subdivided into a roll shape can be produced (for example, refer to non-patent document 1).

According to this device, a small-sized band body is manufactured from a finished masking band, and thus a favorite pattern can be used in both a home and an office or delivered to another person.

However, the conventional apparatus has a disadvantage that the setting (setting) process for rewinding the masking tape of the finished product into a tape core having a small diameter is complicated and the work of the user is difficult.

That is, in the conventional apparatus, it is necessary to first remove one and the other shaft members provided in the apparatus main body from the apparatus main body, respectively, then attach the finished masking tape to the one shaft member removed from the apparatus main body, and attach the small-diameter tape core to the other shaft member removed from the apparatus main body. In addition, after the finished masking tape and the small-diameter tape core are attached to the one and the other shaft members, the one and the other shaft members are forcibly assembled to the apparatus main body again.

The above is not limited to the masking tape, and the same applies to the case of other tapes.

Rotary support mechanism D for belt body T

The rotation supporting mechanism D of the tape T is for flexibly supporting the tape T having various sizes. The rotation support mechanism D of the tape T in this embodiment is provided with the spacer member 3 that is attachable to and detachable from the tape support portion 2, and is configured so that a case where the tape T is supported by the tape support portion 2 to which the spacer member 3 is attached as shown in fig. 20 and a case where the tape T is supported by the tape support portion 2 from which the spacer member 3 is detached as shown in fig. 21 can be selected.

Further, since the belts T that are distributed in the market have various sizes, the belt T used in the rewinding machine of the present embodiment may be a member that is not tightly fitted to the outer periphery of the spacer member 3 or the outer periphery of the cylindrical portion 21 of the belt support portion 2.

As described above, the rewinding device of the present embodiment includes the rewinding device main body a having the tape support portion 2 as the driven shaft, the core support portion 4 as the driving shaft, and the handle 5 as the operation portion, wherein the tape support portion 2 can support the tape T around which the tape tp is wound, the core support portion 4 can support the core E around which the tape tp is drawn out from the tape T, and the handle 5 rotates the core support portion 4 as the driving shaft together with the core E. The tape rewinder includes a cover B supported to be rotatable between an open posture (F) and a closed posture (G) with respect to the tape rewinder body a.

Therefore, it is possible to provide a tape rewinder capable of appropriately performing at least the setting for winding the tape tp pulled out from the tape body T around the tape core E.

That is, since the cover B is configured to be rotatable between the open posture (F) and the closed posture (G) with respect to the rewinder main body a, the cover B can be brought into the open posture (F) to facilitate the operation of attaching or detaching the tape T or the tape core E to or from the rewinder main body a.

The rewinding machine main body a is provided with a cover engagement portion 15 engageable with the cover B. The cover B includes a cover main body 6 and a lock member 7 supported to be slidable with respect to the cover main body 6. The cover B is locked in the closed posture (G) by engaging the lock member 7 with the cover engaging portion 15.

Therefore, the cover B is locked in the closed posture (G) with respect to the rewinder main body a by a simple operation of sliding the lock member 7.

The cover engaging portion 15 is provided to protrude in the direction of the cover B from the rising wall 12 provided on the rewinder main body a.

Therefore, the cover B can be engaged at the intermediate position of the rewinder main body a, and therefore the cover B in the closed posture (G) is appropriately supported by the rewinder main body a.

A backlash restraining means C is provided for restraining the backlash of the cover B with respect to the rewinder body A by elastically engaging the rewinder body A with the cover B.

Therefore, it is possible to appropriately suppress the cover B from being slightly loosened with respect to the tape rewinder main body a. In other words, by providing the looseness inhibiting unit C, it is possible to appropriately inhibit the sense of incongruity to the user that may be generated in the case where the hood B is slightly loosened.

The backlash suppressing means C includes a front wall 13 and a rear wall 14 as first extension plates provided to the tape rewinder main body a, a cover front wall 63 and a cover rear wall 64 as second extension plates provided to the cover B, and first and second pressing projections C1, C2 as abutting portions provided to the front wall 13 and the rear wall 14 and elastically contactable with the cover front wall 63 and the cover rear wall 64.

Therefore, when the cover B assumes the closed posture (G), the first and second pressing projections c1, c2 disposed on the tape rewinder main body a always press the cover front wall 63 and the cover rear wall 64, and therefore, the backlash between the tape rewinder main body a and the cover B can be appropriately suppressed.

Since the first and second pressing protrusions c1, c2 are provided in a convex shape, the backlash can be suppressed with a simple structure.

The rewinder main body a is provided with a ratchet mechanism R for rotating a handle 5 as an operation portion only in one direction, i.e., in a normal rotation direction.

Therefore, the handle 5 can be appropriately prevented from being reversed, so that the belt tp pulled out from the belt body T is less likely to be irregularly wound around the belt core E, and the user's erroneous operation can be prevented.

The present invention is not limited to the embodiments described in detail above.

The tape is not limited to the one in which the masking tape is wound, and may be another tape in which the tape is wound.

The driven shaft may have any structure as long as it can directly or indirectly support the belt body.

The drive shaft may be any shaft as long as it can directly or indirectly support the belt core, and various structures can be applied. For example, the drive shaft may not be connected to the operation handle.

The cover may be supported to be rotatable between an open posture and a closed posture with respect to the rewinder main body, and the form thereof may be set to an appropriate form.

The backlash suppressing means may be realized by always elastically engaging the webbing retractor main body and the cover, and may be in an appropriate form within a range not departing from the spirit thereof.

For example, only one of the first extension plate provided to the tape rewinder main body and the second extension plate provided to the cover may be provided.

The abutting portion may be provided on either one of the first and second extending plates. For example, the pressing projection as the contact portion may be provided on the hood front wall or the hood rear wall.

The portion to which the convex abutting portion elastically abuts may be a flat portion or may not be a groove-like portion.

The specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.
