Description

  The present invention relates to, for example, a tape on which electronic parts are taped, a tape reel for winding a tape made of roll paper, and a reinforcing plate for the tape reel.

  Conventionally, a tape reel 40 made of, for example, plastic for winding tape made of electronic components or tape made of roll paper, for example, is shown in the perspective view of FIG. 5A and the side view of FIG. 5B. As shown, a pair of disc-shaped flanges 42a and 42b are disposed so as to be sandwiched between the pair of flanges 42a and 42b, and both ends are coupled to the center of the circle between the flange 42a and the flange 42b, respectively. And an inner core 44. By being configured in this way, an interval H corresponding to the height of the core 44 is secured as shown in FIG. 5B (see, for example, Patent Document 1).

  This interval H is maintained so as to be narrower than the width of the tape wound by the tape reel 40. For this reason, when winding the tape around the tape reel 40, a guide such as a jig (not shown) having the same width as the tape is inserted into the tape reel 40, and the interval H is increased. Yes. As a result, even if the diameter of the tape reel 40 is increased, the tape can be wound while there is no winding deviation and the occurrence of collapse is avoided.

  However, as the diameter of the tape reel 40 increases, the weight of the tape wound around the tape reel 40 also increases and the flanges 42a and 42b themselves do not have sufficient strength. For example, as shown in FIG. Will be deformed.

  As shown in FIG. 7, when the tape 46 is wound using, for example, a tape reel 40 that has been deformed so that the distance H between the tips of the flanges 42a and 42b is narrowed, the tape 46 may be damaged by coming into contact with the flanges 42a and 42b. In the worst case, there is a fear that the tape 46 cannot be properly wound.

Therefore, as shown in FIG. 8, a tape reel 50 having a radial reinforcing plate 48 on the outer surface of both the pair of flanges 42a and 42b has been developed (see Patent Document 2). The tape reel 50 has reinforcing plates 48 extending radially from the central portion 52 to the peripheral portion 53 of the reel body, that is, along the rib 56 formed between the fan-shaped through holes 55 of the flange 42 along the diameter direction. It is installed.

A reinforcing member 18 for preventing the occurrence is disposed.

  The reinforcing plate 10 according to the embodiment of the present invention not only can reinforce the tape reel 40, but also has the lightening holes 16 as described above and has a rotationally symmetric configuration, thereby realizing weight reduction. In addition, the winding operation of the tape by the tape reel 40 is performed smoothly.

  The reinforcing plate 10 only needs to be at least rotationally symmetric when rotated about the central hole 12 and is not necessarily limited to ¼ rotational symmetry. The reinforcing member 14 is not an essential component and can be omitted. The reinforcing member 18 is not an essential component, and can be omitted if the reinforcing plate 10 itself has sufficient strength.

  FIG. 3 is an outline view showing another configuration example of the reinforcing plate according to the embodiment of the present invention.

  That is, the reinforcing plate 11 shown in FIG. 3 does not include the reinforcing member 14 and the reinforcing member 18, and has a plurality of reduction holes 16 so as to be 1/8 rotationally symmetric when rotated around the center hole 12. It is an example provided.

  Further, the reinforcing plates 10a and 10b are preferably in the shape of a disc having a diameter that is at least as large as the flanges 42a and 42b and larger than the flanges 42a and 42b. Then, the flanges 42a and 42b are disposed on the outer surfaces of the flanges 42a and 42b, respectively, by being firmly fixed to the corresponding flanges 42a and 42b. Therefore, the tape reel 40 can be reinforced efficiently. Furthermore, it is possible to effectively reinforce the tape reel 40 having a large diameter.

  The reinforcing plate 10 is detachably disposed on the flange 42. Therefore, it is not necessary that the tape reels 40 each have the reinforcing plate 10 at all times, and the reinforcing plate 10 can be provided only when necessary. In this way, since the reinforcing plate 10 can be used around, a small number of the reinforcing plates 10 can be used effectively.

  Further, the reinforcing plate 10 is provided with a plurality of reduction holes 16 so as to be rotationally symmetric when rotated about the center hole 12 as an axis. Therefore, it is possible to smoothly perform the winding operation of the tape by the tape reel 40 while realizing weight reduction.

  Therefore, in the tape reel 40 according to the embodiment of the present invention, the reinforcing plate 10 according to the embodiment of the present invention as described above is disposed on the outer surface of the flange 42 only when necessary, such as when winding the tape. This makes it possible to smoothly rewind the tape while effectively reinforcing the flange 42 and preventing deformation. Further, since the reinforcing plate 10 is provided with the reduction holes 16, the tape reel 40 can suppress an increase in weight even when the reinforcing plate 10 is attached.
