Abstract

PURPOSE:To maintain satisfactory state of taping even after winding-up by a take-up reel by specifying the curvature for the round part of a lower guide for an apparatus with which a parts supply tape made up by providing parts- holding parts over a base tape and by sticking a top tape to the surface of the parts-holding parts is wound up by the take-up reel. CONSTITUTION:A parts supply tape 11 made up by providing protuberant parts- holding parts 13 on a base tape 12 is supplied from a supply reel and is guided between an upper guide 3 and a lower guide 4, and a top tape 21a supplied from a supply reel 21 is stuck over the parts supply tape while both of the tapes are caught between the lower guide 4 and a pressing roller 5. After that, the tapes stuck together are made to pass under an upper guide 6 and are wound up by a take-up reel. The radius of curvature on the round part R of the lower guide 4 is made smaller than the radius of the inner diameter of the take-up reel. As a result, excessive tension is applied neither to the top tape 21a nor the base tape 12 even after the parts supply tape 11 is wound up by the take-up reel, and thereby satisfactory state of taping can be maintained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a taping device for taping parts.

[0002]

2. Description of the Related Art FIG. 5 is a perspective view of a component supply tape 51 used in a conventional taping device, showing an equal pitch interval (=
P) to the base tape 52 having the feed hole 54,
A box-shaped portion 53 for housing 3a is attached. In this case, the box-shaped portion 53 has a shape protruding downward from the base tape 52.

A conventional taping device generally has a structure as shown in FIG. That is, the sprockets of the feed wheel 42 shown in FIG. 4 are fitted into the feed holes 54 provided at equal pitch intervals (= P) of the component supply tape 51 shown in FIG. 5, and fed in the direction of the arrow in FIG. There is.

The taping roller 43 and the tape lower part guide 44 are located upstream of the feed wheel 42, and the component insertion portion is located further upstream thereof. After the components are inserted, the taping roller 43 sandwiches the top tape 45 and the component supply tape 51, which are supplied from the upstream side, and presses them against the tape lower guide 44.

The taped component supply tape 51 is wound on a tape recovery reel (not shown).

[0006]

However, the taping device having the above construction is effective for the component supply tape 51 having the component holding portion 53 which is convex downward with respect to the base tape 52 as shown in FIG. However, there are the following problems with the component supply tape 11 having the component holding portion 13 having a convex shape above the base tape 12 as shown in FIG.

That is, in the conventional configuration as shown in FIG. 5, the state after the component supply tape 11 and the top tape 45 are pasted together is as shown in FIG. 6, and the component supply tape having such a shape is collected. When the tape is wound onto the reel 61, there is a problem that the tension of the top tape 45a between the component holding portions 13 and the component holding portion 13 becomes excessive as shown in FIG. The present invention is to solve the above problems,
An object of the present invention is to provide a taping mechanism capable of winding a component supply tape having a convex component holding portion upward from the base tape and winding it on a recovery reel without excessive tape tension.

[0008]

In order to achieve the above object, the present invention provides a top tape in openings on the upper surface of component holding portions at equal intervals protruding from the upper surface of a base tape of a flexible long tape. A taping device for winding the flexible long tape around a recovery reel after being stuck together and sealed, and a lower guide for guiding the lower surface of the base tape of the long tape, and the component holding by sandwiching the top tape. A pressing roller having an elastic force that exerts a pressing force from the opening side of the lower portion toward the lower guide, and the radius of curvature of the guide surface of the lower guide is smaller than the minimum winding radius of the recovery reel. Is.

[0009]

According to the present invention, when the opening of the component holding portion is sealed with the top tape, the component holding portion has a shape protruding upward from the base tape of the flexible long tape. After the top tape is attached, the flexible long tape can be wound around the recovery reel without applying excessive tension to the flexible long tape and the top tape.

【Example】

(Embodiment 1) A taping device according to an embodiment of the present invention will be described with reference to FIGS.

In a taping device according to an embodiment of the present invention, a component supply tape 11 having a convex component holding portion 13 on the upper surface of a base tape 12 as shown in FIG. The sprocket of the feed wheel 2 is inserted into the feed holes 14 provided from the component supply tape 11 at equal pitch intervals (= P) and fed in the direction of arrow B.

The component supply tape 11 is guided by the upper guide A3 and the lower guide 4, is attached to the top tape 21a supplied from the supply reel 21 in a form of being sandwiched between the lower guide 4 and the pressing roller 5, and the upper guide B6 is attached. After passing, it is wound on a recovery reel (not shown).

The radius of curvature of the R portion of the lower guide 4 is made smaller than the radius of the winding inner diameter of the recovery reel (not shown). Therefore, even after the component supply tape 11 is wound on the recovery reel, it is possible to maintain a good taping state without applying excessive tension to the top tape and the base tape.

The pressing roller 5 is in elastic contact with the component supply tape 11 by the shaft 7, the bracket 8, the spring 9, and the pressing plate 10, and the irregularities of the component holding portion 13 when passing through the pressing roller 5 are provided. It can move up and down in response to exercise.

(Second Embodiment) Next, a second embodiment will be described with reference to FIG.

The taping device of the second embodiment of the present invention uses a component supply tape 11 having a convex component holding portion 13 on the upper surface of the same shape as that shown in FIG. 2, and as shown in FIG. It is attached to the top tape 21a in the same process as in FIG.

That is, the component supply tape 11 is guided by the upper guide A3 and the lower guide 4, and is sandwiched between the lower guide 4 and the pressing roller 5 to form the top tape 21a.
Pasted together. Immediately after that, since the tip of the flexible curtain 32 held by the bracket 32 is in contact with the upper surface of the top tape, the top tape 21b between the component holding portions 13 is bent upward or bulged. Is preventing. The component supply tape 11 that has passed through the upper guide B6 is wound on a recovery reel (not shown) as in the case of the first embodiment.

The radius of curvature of the R portion of the lower guide 4 is made smaller than the radius of curvature of the winding inner diameter of the recovery reel (not shown). Therefore, a good taping state can be maintained even after the component supply tape 11 is wound on the recovery reel.

[0019]

In the taping device of the present invention, since the lower guide for guiding the component supply tape has a radius of curvature smaller than the inner diameter of the component supply tape recovery reel, the component protruding in a convex shape on the upper surface of the base tape. Even when taping the component supply tape having the holding portion, the top tape can be smoothly wound on the take-up reel without being applied with an excessive tension in a state of being wound on the recovery reel. Furthermore, by providing a flexible curtain immediately after taping, the top tape can be inserted between the component holding portions to prevent the top tape from peeling off and maintain a good taping state.
