Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a top tape take-up reel in a tape feeder that uses an electronic component storage tape to supply electronic components stored in the electronic component storage tape one by one to an electronic component automatic mounting apparatus.
[0002]
[Prior art]
A first flange that is a drive side flange, a second flange that is detachably coupled to the first flange, a winding portion that is provided on the second flange side and has an expandable / contractible outer periphery, and an outer periphery of the second flange. The take- up reel of the top tape in the tape feeder configured to be held in a diameter state and capable of winding the top tape is already known from, for example, Japanese Patent Laid-Open Nos. 5-186145 and 6-61687. Yes.
[0003]
[Problems to be solved by the invention]
Conventionally known take-up reels of this type are mainly intended to facilitate the removal of the top tape taken up by each of them. A slit is formed in the winding portion that winds up, and a part of the winding portion is deformed in the radial direction, or the winding portion is formed by a pair of arc-shaped members. There is a method in which members are provided close to and away from each other, and the outer peripheral shape of the winding portion is changed by rotating a rotary lever provided between them. The former type is disclosed in JP-A-5-186145. The latter type is described in JP-A-6-61687, etc., respectively.
[0004]
As described above, the tape feeder is used to supply electronic components to the electronic component automatic mounting apparatus. In order to improve the efficiency of the supply operation, the top wound on the take-up reel is used. A significant reduction in the time required to remove the tape is required.
Then, in order to significantly reduce the time required for removal of the top tape wound up, the frictional resistance acting during a manual winding off operation from the first flange of the second flange is reduced, the removal operation that you to make easily is requested.
Since the above-described conventional example has the above-described configuration, it is inevitable that the frictional resistance is increased, and it is difficult to sufficiently satisfy the above-described demands required for the take-up reel.
[0005]
The present invention has been made to meet the above-described demands, and enables the top tape wound around the take-up reel to be removed extremely quickly and easily, so that the electronic component is mounted on the electronic component automatic mounting apparatus. The main object of the present invention is to provide a top tape take-up reel in a tape feeder that can contribute to an improvement in supply work efficiency.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a take-up reel according to the present invention includes a first flange, a second flange detachably coupled to the first flange, and an expandable / contractible top tape provided between the two flanges.
