Description

  The present invention relates to a film or a film obtained by cutting a film material such as an adhesive layer or a pressure-sensitive adhesive layer or a film material such as an adhesive layer or a pressure-sensitive adhesive layer that has been formed into a thin tape. Alternatively, the present invention relates to a reel for winding and unwinding a sheet or the like (referred to as a material to be wound as appropriate).

Conventionally, a reel that winds and unwinds an object to be wound cut into a narrow tape has been used in various fields.
For example, there is a reel that winds and unwinds a carrier tape in which a pocket for storing electronic components is formed, a seal tape for packing a carrier tape in which electronic components are stored, and the like.

The reel that winds and unwinds the above-described seal tape is used in a taping device for electronic components (for example, see Patent Document 1).
This electronic component taping device feeds a seal tape by operating a transport mechanism that transports a carrier tape, a placement mechanism that places the electronic component on the carrier tape transported by the transport mechanism, and a drive source. A seal tape delivery mechanism, a seal tape tension control mechanism for controlling the tension of the seal tape delivered from the seal tape delivery mechanism, and a crimping mechanism for crimping the seal tape to a carrier tape on which electronic components are placed. I have.
This technique aims to reduce trouble caused by a tape by unwinding a thin film tape from a reel and controlling the tension of the tape to be constant.

Various technologies have also been developed for reels for winding and unwinding the material to be wound.
For example, in Patent Document 2, a pair of reel flanges, a winding core that couples these reel flanges and winds a carrier tape, and a spring that is housed inside the winding core and biases each reel flange inwardly. When the carrier tape is wound up, the distance between the pair of reel flanges is set within a range where the carrier tape can be wound and narrower than the width of the carrier tape. A carrier tape reel technique characterized by pressing a side surface of a carrier tape is disclosed.
According to this technique, since the carrier tape can be wound in a state where each reel flange presses the side surface of the carrier tape, it is possible to prevent the carrier tape from being unwound or collapsed.

Patent Document 3 and Patent Document 4 disclose a reel technique including a shaft portion for winding a tape and a pair of side plates having a metal reinforcing material and a reel side plate correction tool. . According to this technique, it is said that winding slip and collapse can be prevented.
Further, in Patent Document 5, the thickness is controlled by inserting and exhausting air between the flange of the open reel for magnetic tape and the side end of the magnetic tape wound around the open reel. A technique for a spacer for an open reel made of a cushion member having a thin film shape and airtightness is disclosed. According to this technology, it is said that the side end portion (edge) of the tape wound around the open reel during transportation or the like can be prevented from being wound and damage to the tape side end portion can be prevented. .

  However, as a result of extensive studies by the present inventors, in the technique disclosed in Patent Document 1, the tension control described above is required when a tape having a small width (for example, from several millimeters to several millimeters) is unwound from a reel. Alone, we have found that there is still a problem to be solved in unwinding stably. That is, no matter how accurately the tension is controlled, as the tape width becomes narrower, the unwinding position of the tape to be unwound tends to fluctuate in the axial direction of the reel, and the unwinding position of the tape becomes constant. It turned out to be difficult to keep.

  Moreover, in the technique disclosed in Patent Document 2, since each reel flange is to wind the carrier tape in a state of pressing the side surface of the carrier tape, it is inevitable that a load is applied to the side surface of the tape during winding. There was a problem that the side surface of the tape was easily damaged. In particular, in a tape on which an adhesive layer or an adhesive layer is formed, there is a concern that the adhesive layer or the adhesive material layer may adhere to the reel flange.

In addition, when the reel is a reel that winds and unwinds the above-described seal tape, the reel can correspond to various tape widths and taping devices according to various shapes and sizes of electronic components. There was a need. That is, it is demanded that it is easy to use and the like, and that each component of the reel can be shared.
In addition, although the technique of patent documents 3-5 is a technique relevant to this invention, it cannot solve said subject and cannot respond to said request.

  The present invention has been made based on the inventor's examination as described above, and it is possible to stabilize the work such as winding the wound object and unwinding and using the wound object. The purpose of the present invention is to provide a reel capable of improving the performance.

  In order to achieve the above object, the reel of the present invention includes a winding unit around which the article to be wound is wound, and a first side plate provided in the winding unit so as to be orthogonal to the axial center direction of the winding unit, It is set as the structure provided with the 2nd side plate provided in the winding part so that the movement to the axial direction was possible facing the 1st side plate so that the to-be-winded thing wound may be pinched | interposed.

By adopting such a configuration, when winding the wound object, a predetermined gap is formed between the side surface of the wound object and the second side plate, so that the wound object is not damaged or wound. It can be effectively suppressed.
In addition, after the winding is completed, the second side plate is moved so as to press the side surface of the wound object with the second side plate, thereby correcting the winding of the wound object or suppressing the collapse. You can do it. Furthermore, when the object to be wound is unwound and unwound, the object to be wound is sent out while being sandwiched between the first side plate and the second side plate. The position can be prevented from moving in the axial direction of the reel.
Therefore, when the reel of the present invention is used to manufacture a tape to be wound around a reel while cutting the film material into a thin width or to supply the tape wound around the reel, when the tape as the material to be wound is wound In addition, when unwinding and using, the stability of the work can be improved.

  In addition, when the reel of the present invention winds up the wound object, the second side plate is opened after a predetermined gap is formed between the side surface of the wound object and the second side plate and the winding is finished. A locking means for locking the second side plate so as to leave a predetermined gap with respect to the wound object when the wound object is wound in order to press the side surface of the wound object with A structure including an urging unit that presses the wound article to be wound when the second side plate is urged, and the article to be wound is wound up and then released by the locking means. can do.

Moreover, the reel of this invention can be set as the structure by which the urging | biasing means was provided between the 2nd side plate and the latching plate.
By setting it as such a structure, the urging | biasing force from an urging means can be efficiently acted with respect to a 2nd side plate.

In addition, the reel of the present invention can be configured to include stopper means for preventing the biased second side plate from moving too much in the pressing direction. By adopting such a configuration, even when the wound object is unwound and the remaining amount of the wound object is reduced, the remaining wound object is not excessively pressed, and the wound object is not pressed. Problems such as damaging the wound material can be avoided.

The reel of the present invention includes a dedicated core in which a winding portion has a shaft hole having a predetermined shape, and a shared core that is detachably attached to the outer peripheral surface side of the dedicated core, and the first side plate The second side plate and the locking plate can be detachably attached to the common core.
By adopting such a configuration, it is possible to share components even when it is necessary to cope with various shaft hole shapes.

Further, in the reel of the present invention, in order to effectively suppress damage and winding deviation when winding the wound object, the predetermined gap between the side surface of the wound object and the second side plate is 0. It is preferable to set it as 1 mm-2.0 mm, and also within the range, it is preferable to set it as 10 to 40% with respect to the width dimension of a to-be-winded thing.
Furthermore, as the biasing means used for the reel of the present invention, an elastic body or a bubble cushioning material can be used.

  According to the reel of the present invention, it is possible to improve the stability of work such as when winding the wound object and when unwinding and using the wound object.

[First embodiment]
FIG. 1 is a schematic view of a reel according to a first embodiment of the present invention, in which (a) shows a side view and (b) shows a plan view.
In FIG. 1, the reel 1 according to the present embodiment includes a winding unit 2, a first side plate 3, a second side plate 4, a locking plate 5, a spring 6, and the like. The reel 1 can wind up and unwind the tape 10 as an article to be wound.
The tape 10 is not particularly limited, and may be, for example, a tape, a film, or a sheet cut into a narrow tape shape. Moreover, you may have an adhesive bond layer, an adhesive layer, etc., or do not need to have it.

(Winding part)
The winding portion 2 has a substantially cylindrical shape with a shaft hole through which a winding shaft (not shown) or the like passes, and the tape 10 is wound around the outer peripheral surface. The winding portion 2 is usually made of resin, but may be made of metal such as aluminum or a composite material made of resin and metal. Moreover, although the shaft hole which has a keyway is formed in the winding-up part 2, the shape of a shaft hole is not limited to this, It can be made into various shapes.

(First side plate)
The first side plate 3 has a substantially annular plate shape and is provided at one end of the winding portion 2 so as to be orthogonal to the axial direction of the winding portion 2. The first side plate 3 is usually made of resin, and is molded integrally with the winding unit 2 in the present embodiment. The first side plate 3 is not limited to this configuration, and may be made of a metal such as aluminum, and is fixed to the winding unit 2 by adhesion, welding, screwing, or the like. Also good.

(Second side plate)
The second side plate 4 has a substantially annular plate shape and moves in the axial direction of the winding unit 2 toward the other end of the winding unit 2 so as to be orthogonal to the axial direction of the winding unit 2. It is provided as possible. That is, the second side plate 4 is provided to face the first side plate 3 so as to sandwich the wound tape 10. The second side plate 4 is usually made of resin, but may be made of metal such as aluminum. Further, the second side plate 4 is integrally formed with a locking portion 41 described later.

(Locking means)
The locking means of the present embodiment includes a locking portion 41 protruding from the outer side surface (the surface opposite to the tape 10) of the second side plate 4, and a position corresponding to the locking portion 41. And a locking plate 5 in which a locking hole 51 is formed.
The locking portion 41 has a substantially rectangular plate shape, and has a guide surface (slope) and a locking surface on the tip side. Further, the locking portions 41 are disposed at substantially equal intervals at four locations in the circumferential direction of the second side plate 4.

  The locking plate 5 has a substantially annular plate shape, and is provided at the other end of the winding unit 2 so as to be orthogonal to the axial direction of the winding unit 2. As described above, the locking plate 5 has a substantially rectangular locking hole 51 at a position corresponding to the locking portion 41, and is fixed to the winding portion 2 by adhesion, welding, screwing, or the like. Has been. The locking plate 5 is usually made of resin, but may be made of metal such as aluminum.

When the tape 10 is wound around the take-up portion 2, the above-described locking means is such that the locking portion 41 is inserted into the locking hole 51, and the locking surface of the locking portion 41 is engaged with the outer surface of the locking plate 5. Stopped. As a result, the locking means of the present embodiment locks the second side plate 4 at a position that leaves a predetermined gap Δ with respect to the tape 10.
In addition, if the latching means with which the reel 1 is provided is engaged with another member such as the latch plate 5 and can stop (lock) the second side plate 4 at a predetermined position, the specific mode is as follows. The examples are not limited to the above.

  Here, preferably, the predetermined gap Δ is set to 0.1 mm to 2.0 mm. The reason is that if the predetermined gap Δ is less than 0.1 mm, both sides of the tape 10 may come into contact with the first side plate 3 and the second side plate 4, and damage to both side ends of the tape 10 occurs. Because there are cases. In addition, if the predetermined gap Δ exceeds 2.0 mm, the effect of suppressing winding deviation may not be sufficiently exhibited.

More preferably, the predetermined gap Δ is within the range of 0.1 mm to 2.0 mm from the viewpoint of workability and winding deviation suppression (that is, the width dimension of the tape 10 to be wound (that is, the coverage). 10% to 40%, preferably 10% to 30%, more preferably 10% to 20% with respect to the length along the axial direction of the tape 10 as a wound product. More preferably, it is particularly preferably 10 to 15%. For example, when the width dimension of the tape 10 is 2 mm, the predetermined gap Δ is preferably 0.2 mm to 0.8 mm, more preferably 0.2 mm to 0.6 mm, and 0.2 mm to It is more preferable to set it as 0.4 mm, and it is especially preferable to set it as 0.2 mm-0.3 mm. When the width dimension of the tape 10 is 0.9 mm, the predetermined gap Δ is preferably 0.1 mm to 0.36 mm, more preferably 0.1 mm to 0.27 mm. More preferably, the thickness is 0.1 mm to 0.18 mm, and particularly preferably 0.1 mm to 0.14 mm. The reason for this is that even if a winding deviation within 40% of the width dimension of the tape 10 occurs, the winding deviation can be easily corrected by the second side plate 4 pressing the tape 10 as will be described later. Because.
In this way, the predetermined gap Δ is set to 0.1 mm to 2.0 mm, more preferably 10% to 40% with respect to the width dimension of the tape 10 to be wound, to the tape 10. Can be effectively suppressed and workability is improved.

(Biasing means)
The biasing means of this embodiment is a spring 6, and the spring 6 is provided between the second side plate 4 and the locking plate 5. These springs 6 urge the second side plate 4 in the direction of the first side plate 3, and after the tape 10 is wound up, the second biased plate 6 is biased when the locking by the locking means is released. The side plate 4 presses the wound tape 10. Thereby, winding deviation can be corrected easily and the occurrence of collapse can be prevented. Further, when the tape 10 is unwound, the unwinding position of the tape 10 to be fed can be prevented from moving in the axial direction of the reel 1, and stable unwinding can be performed.

Here, preferably, at least three or more springs 6 may be arranged at substantially equal intervals in the circumferential direction at substantially the center in the radial direction of the second side plate 4. That is, in the present embodiment, the eight springs 6 are arranged at equal intervals in the circumferential direction at substantially the center portion in the radial direction of the second side plate 4 (≈ (radial position of (the outer diameter of the second side plate 4 + the inner diameter) / 4)). Arranged. If it does in this way, the tape 10 with which the 2nd side board 4 was wound up can be pressed with a substantially equal pressure, and the trouble that the tape 10 is pushed too much locally and damages the tape 10 is avoided. be able to.
Note that the spring constant and the free length of the spring 6 are appropriately set according to the mechanical strength of the tape 10 and the like. Further, the urging means included in the reel 1 presses the second side plate 4 in a predetermined direction (ie, urges it) so that the wound tape 10 as the material to be wound is pressed by the second side plate 4. Other alternative means other than the spring 6 may be used if it can be done. For example, elastic bodies other than springs such as rubber, flexible urethane foam, expanded polystyrene (expanded polystyrene), expanded polyethylene sheet, sponge, bubble sheet (for example, “Puchipuchi” manufactured by Kawakami Sangyo Co., Ltd.), bubble board (for example, A bubble cushioning material (air pack) such as “Purapearl” manufactured by Kawakami Sangyo Co., Ltd.) may be used.

Next, operation | movement of the reel 1 of the said structure etc. are demonstrated with reference to drawings.
FIG. 1 shows a state where the reel 1 takes up the tape 10.
As shown in FIG. 1, first, in the reel 1, the second side plate 4 is moved in the direction opposite to the first side plate 3, the locking portion 41 is engaged with the locking hole 51, and the second side plate 4 is Locked to the locking plate 5.
Next, the reel 1 is attached to a take-up shaft (not shown) of the take-up device, and the tip of the tape 10 is attached to the take-up portion 2 with an adhesive or the like. At this time, the tape 10 is affixed in a state where the end on one side is substantially in contact with the first side plate 3.

Subsequently, the winding shaft rotates in the winding direction, and the tape 10 is wound around the winding unit 2.
Here, the tape 10 is usually wound in a state where the end on one side is substantially in contact with the first side plate 3. Further, the reel 1 is locked at a position where the second side plate 4 has a predetermined gap Δ with respect to the tape 10 by the locking means described above. Thereby, as above-mentioned, the damage and winding slip to the tape 10 can be suppressed effectively.

Next, when the tape 10 having a predetermined length is wound around the reel 1, the winding shaft of the winding device stops rotating. Subsequently, the operator cuts the tape 10, fastens the end of the cut tape 10 with a paper tape with an adhesive, and further releases the locking of the locking portion 41. As a result, the reel 1 presses the tape 10 on which the second side plate 4 is wound by the spring 6 toward the first side plate 3. By this pressing, the reel 1 can correct the winding deviation of the tape 10 and suppress the winding collapse.
Next, the operator removes the reel 1 that has completed the winding operation from the winding shaft, and conveys the reel 1 to the next process (for example, an inspection process or a shipping process).

2A and 2B are schematic diagrams for explaining the unwinding state of the reel according to the first embodiment of the present invention. FIG. 2A is a side view and FIG. 2B is a plan view. .
In FIG. 2, the shipped reel 1 is attached to, for example, the unwinding shaft (not shown) of the electronic device taping device described above, and the tape 10 is unwound.
Here, the tape 10 unwound from the reel 1 is sent out while being sandwiched between the first side plate 3 and the second side plate 4. That is, it is possible to prevent the unwinding position of the tape 10 to be fed out in the axial direction of the reel 1, and stable unwinding becomes possible.

Further, even when the tape 10 is fed out and the remaining amount of the tape 10 is reduced, the tape 10 in which the second side plate 4 remains with a substantially equal pressure by the plurality of springs 6 disposed at the above-described positions. Can be pressed. Thereby, even if the remaining amount of the tape 10 decreases, it is possible to avoid a problem that the tape 10 is pressed too much locally and damages the tape 10.
Next, when the unwinding of the tape 10 is completed, the operator removes the reel 1 from the unwinding shaft, and the unwinding operation of the reel 1 is completed.

  As described above, according to the reel 1 of the present embodiment, in manufacturing the tape 10 wound around the reel 1 while cutting the film material into a thin width, and supplying the tape 10 wound around the reel 1, the tape 10 Winding, damage to the tape 10 can be suppressed, and when the tape 10 is unwound and used, the unwinding position of the tape 10 should not be shaken in the axial direction of the reel 1. And stable unwinding becomes possible. Accordingly, it is possible to improve the stability of work such as when winding the tape 10 and when unwinding and using the tape 10.

[Second Embodiment]
FIG. 3 is a schematic view of a reel according to the second embodiment of the present invention, wherein (a) shows a side view and (b) shows a plan view.
FIG. 4 is a schematic enlarged view including a portion A in FIG.
3 and 4, the reel 1a of the present embodiment has a winding core 2a with a dedicated core 21 having a shaft hole having a predetermined shape compared to the reel 1 of the first embodiment described above. The common core 22 is detachably attached to the outer peripheral surface of the dedicated core 21, and the first side plate 3a, the second side plate 4, and the locking plate 5a are detachably attached to the common core 22. And the point by which the stepped part 223 is formed in the common core 22 is different. In addition, the other structure of this embodiment is as substantially the same as the reel 1 of 1st embodiment. Therefore, in FIGS. 3 and 4, the same components as those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted.

The winding unit 2 a of the present embodiment has a dedicated core 21 and a shared core 22.
The dedicated core 21 has a substantially cylindrical shape with a shaft hole through which a take-up shaft (not shown) or the like passes. Further, the dedicated core 21 is provided with locking claws 211 projecting at a plurality of locations on the outer peripheral surface side of both ends (in this embodiment, four locations positioned at equal intervals in the circumferential direction) (see FIG. 4). . With these locking claws 211, the shared core 22 is detachably attached to the outer peripheral surface of the dedicated core 21. By doing in this way, the exclusive core 21 corresponding to various shaft holes specified by the customer can be easily attached, and the service can be improved in response to the customer's request. Furthermore, the dedicated core 21 has a key-shaped convex portion 212 formed in the axial direction of the outer peripheral surface. This convex part 212 fits into the concave part 221 of the shared core 22 and transmits torque (see FIG. 3B).

  The shared core 22 has a substantially cylindrical shape fitted to the outer peripheral surface of the dedicated core 21, and the first side plate 3a is provided at a plurality of locations on the both end surfaces (in the present embodiment, four locations positioned at equal intervals in the circumferential direction). The boss 31 and the boss hole 222 into which the boss 52 of the locking plate 5a is inserted are formed (see FIG. 4). Further, the shared core 22 has a recess 221 that fits with the above-described protrusion 212 in the axial direction of the inner peripheral surface. The common core 22 has the tape 10 wound around the outer peripheral surface (the outer peripheral surface of a stepped portion 223 described later), and the second side plate 4 can move in the axial direction in a range excluding the stepped portion 223. It is attached.

  The shared core 22 has a substantially cylindrical stepped portion 223 protruding from the outer peripheral surface on the first side plate 3a side. The stepped portion 223 has a length in the axial direction of W−Δ1. Here, W is the width dimension of the tape 10, Δ1 is the width dimension by which the tape 10 is pressed in the axial direction by the spring 6 (biasing means), and is 0 to 0.00. It is set to several mm (for example, 0.1 to 0.2 mm). When the latching of the second side plate 4 is released without the tape 10, the side surface (stepped surface) of the stepped portion 223 comes into contact with the moved second side plate 4. That is, the stepped portion 223 is a stopper means for preventing the biased (and unlocked) second side plate 4 from moving too much in the pressing direction (the direction toward the first side plate 3a). Function as.

For example, when the width dimension W of the tape 10 is 0.8 mm and Δ1 is 0.2 mm, the length W−Δ1 in the axial direction of the stepped portion 223 is 0.6 mm. Here, although the length W−Δ1 of the stepped portion 223 around which the tape 10 is wound is shorter than the width dimension W of the tape 10, the short portion is minute, so that the tape 10 has no problem as shown in FIG. 4. It is wound up.
When the locking by the locking means is released from this state, the second side plate 4 moves toward the tape 10 and comes into contact with the tape 10.
Further, as shown in FIG. 5, when the tape 10 is further unwound and the remaining amount of the tape 10 is reduced (for example, when the winding thickness of the tape 10 is several mm to several mm, for example), The side plate 4 further moves in the pressing direction toward the first side plate 3a by a distance Δ1 (for example, 0.2 mm), stops in contact with the stepped portion 223. Therefore, the distance between the first side plate 3a and the second side plate 4 is W−Δ1.

In this way, even when the tape 10 is unwound and the remaining amount of the tape 10 is reduced, the remaining tape 10 is not pressed too much, and the problem of damaging the tape 10 is avoided. be able to. Similarly, even when the remaining amount of the tape 10 is reduced, it is possible to suppress the problem that the end portion on the outer diameter side of the second side plate 4 is too close to the first side plate 3a. Can be sent out normally (for example, without being bent or bent so as to damage the tape 10).
Furthermore, the degree of freedom when setting the spring constant, the free length, and the like of the spring 6 can be increased, and a more suitable pressing force can be set.

  The first side plate 3a has a substantially annular plate shape, and is detachably attached to one end surface of the shared core 22 so as to be orthogonal to the axial direction. That is, as described above, the first side plate 3a has bosses at a plurality of locations (in the present embodiment, four locations positioned at equal intervals in the circumferential direction) on the inner side surface (the surface on the tape 10 side) of the inner edge portion. 31 is protrudingly provided. When these bosses 31 are inserted into the boss holes 222 of the shared core 22, the first side plate 3 a is detachably attached to one end face of the shared core 22.

  The locking plate 5a has a substantially annular plate shape, and is detachably attached to the other end surface of the common core 22 so as to be orthogonal to the axial direction. That is, as described above, the locking plate 5a has bosses at a plurality of positions (in the present embodiment, four positions positioned at equal intervals in the circumferential direction) on the inner surface (surface on the tape 10 side) of the inner diameter side edge. 52 is protrudingly provided. When these bosses 52 are inserted into the boss holes 222 of the shared core 22, the locking plate 5 a is detachably attached to one end surface of the shared core 22.

The second side plate 4 has substantially the same configuration as that of the first embodiment, and has a substantially annular plate shape. The second side plate 4 is provided on the other end side of the shared core 22 so as to be movable in the axial direction of the shared core 22 within a range excluding the stepped portion 223 so as to be orthogonal to the axial direction. .
Other configurations and operations are substantially the same as those of the reel 1 of the first embodiment.

  As described above, according to the reel 1a of the present embodiment, the same effects as the reel 1 of the first embodiment can be obtained, and various shaft holes designated by the customer can be easily handled. Value can be improved. Moreover, since the 1st side plate 3a, the 2nd side plate 4, the latching plate 5a, etc. can be shared, the cost reduction of manufacturing cost can be aimed at. Furthermore, even when the tape 10 is unwound and the remaining amount of the tape 10 is reduced, the remaining tape 10 is not pressed too much, and a problem such as damage to the tape 10 can be avoided. .

[Third embodiment]
FIG. 6 is a schematic diagram of a reel according to the third embodiment of the present invention, in which (a) shows a side view and (b) shows a plan view.
FIG. 7 is a cross-sectional view taken along the line BB in FIG.
6 and 7, the reel 1b of the present embodiment includes a pressing direction stopper 42, a split pin 43, and a shim 44 instead of the stepped portion 223, as compared with the reel 1a of the second embodiment described above. The difference is that a stopper means is provided. In addition, the other structure of this embodiment is as substantially the same as the reel 1a of 2nd embodiment. Therefore, in FIGS. 6 and 7, the same components as those in FIGS. 3 and 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

The winding unit 2b of the present embodiment includes a dedicated core 21 and a shared core 22b. The dedicated core 21 has substantially the same configuration as that of the second embodiment.
The shared core 22b is different from the second embodiment in that the stepped portion 223 is not formed (that is, the outer peripheral surface is a cylindrical outer peripheral surface without a step). Other configurations are substantially the same as those of the shared core 22 of the second embodiment.

  The locking plate 5b is different from the second embodiment in that a through hole 53 into which a pressing direction stopper 42 described later is inserted is formed. These through holes 53 are arranged at substantially equal intervals at four locations in the circumferential direction of the locking plate 5b. An annular shim 44 having a thickness t is attached to the edge of the through hole 53. Other configurations are substantially the same as those of the locking plate 5a of the second embodiment.

  The second side plate 4b is different from the second embodiment in that a substantially cylindrical pressing direction stopper 42 protrudes from the outer surface (the surface opposite to the tape 10). These pressing direction stoppers 42 are disposed at substantially equal intervals at four locations in the circumferential direction of the second side plate 4b, and further, split pins 43 are attached to the distal end portions of the pressing direction stoppers 42. Other configurations are substantially the same as those of the second side plate 4 of the second embodiment.

  Here, the above-mentioned pressing direction stopper 42, split pin 43 and shim 44 are moved in the pressing direction (the direction of the first side plate 3a) when the second side plate 4 which has been urged (and unlocked) is moved. It functions as a stopper means for preventing the excess. That is, as shown in FIG. 7, in the state in which the second side plate 4b is locked by the locking means, the width dimension of the tape 10 is W, and a predetermined width between the tape 10 and the inner side surface of the second side plate 4b. The gap is Δ, the thickness of the shim 44 is t, and the distance between the shim 44 and the split pin 43 is Δ2 (Δ2 ≧ Δ).

When the locking by the locking means is released from this state, the second side plate 4b moves toward the tape 10 by the distance Δ and comes into contact with the tape 10.
Further, as shown in FIG. 8, when the tape 10 is further unwound and the remaining amount of the tape 10 is reduced (for example, when the winding thickness of the tape 10 is several mm to several mm, for example), The side plate 4b further moves in the pressing direction toward the first side plate 3a by a distance (Δ2-Δ), and the split pin 43 comes into contact with the shim 44 and stops. Usually, the distance (Δ2−Δ) is 0 to 0. It is set to several mm (for example, 0.1 to 0.2 mm). Therefore, the distance between the first side plate 3a and the second side plate 4b is W− (Δ2−Δ).

  In this way, even when the tape 10 is unwound and the remaining amount of the tape 10 is reduced, the remaining tape 10 is not pressed too much, and the problem of damaging the tape 10 is avoided. be able to. Similarly, even when the remaining amount of the tape 10 is reduced, it is possible to suppress the problem that the end portion on the outer diameter side of the second side plate 4b is too close to the first side plate 3a. Can be sent out normally (for example, without being substantially bent or bent to damage the tape 10).

  Also, the width of the tape 10 varies, for example, from 0.8 mm to 2.4 mm, there are nine width dimensions for every 0.2 mm pitch, and from 2.5 mm to 5.5 mm, 0 When there are 7 types of width dimensions for every 5 mm pitch, 16 types of reels are required to accommodate each tape width. On the other hand, the reel 1b of the present embodiment can share the detachable first side plate 3a, the second side plate 4b, the locking plate 5b, and the like in substantially the same manner as in the second embodiment. Cost reduction.

Furthermore, in the present embodiment, by using the shims 44 having different thicknesses t, it is possible to share the shared core 22b. That is, in a state where the second side plate 4b is locked by the locking means, the reel 1b is set so that the separation distance (reel inner dimension) between the first side plate 3a and the second side plate 4b is 2.5 mm, for example. When designed, the predetermined gap Δ between the tape 10 and the inner side surface of the second side plate 4b can be preferably set in a range of 0.1 mm to 2.0 mm. In this case, 0.5 mm to 2.4 mm With respect to the tape 10 having the width dimension, the locking means can exert its function. And the reel 1b of this embodiment is provided with said stopper means, By using the shim 44 from which thickness t differs, the spring 6 as an urging | biasing means is said 0.5 mm-2.4 mm. It is possible to deal with the width dimension, and it is possible to avoid problems such as excessive pressing of the tape 10. As described above, since the shared core 22b can be shared, the manufacturing cost can be further reduced.
Other configurations and operations are almost the same as those of the reel 1a of the second embodiment.

  As described above, according to the reel 1b of the present embodiment, the same effects as the reel 1a of the second embodiment can be obtained, and the shared core 22b can be shared. The manufacturing cost can be reduced. Further, the reel 1b can be applied to the tape 10 having different width dimensions (for example, 0.5 mm to 2.4 mm) by exchanging the shim 44, so that the usability and added value are greatly improved. Can be improved.

  The reel of the present invention has been described with reference to a preferred embodiment. However, the reel according to the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. Needless to say.

  For example, although not shown, the spring 6 may be configured to be press-fitted into a substantially cylindrical convex portion projecting from the second side plate 4 and the locking plate 5. Can be attached to.

  Although not shown, the reel 1a or the like may have a structure in which ribs are provided on the dedicated core 21 and the common core 22 to reduce the weight while maintaining the mechanical strength. Moreover, it is good also as a structure which provides a some opening part in the 1st side board 3a and the 2nd side board 4, and aims at weight reduction.

  The present invention can also be implemented by appropriately combining the configurations of the above-described embodiments.
