Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a fiber reinforced resin (FR
P) a filament winding molding apparatus for winding a thread impregnated with a resin and a method of using the filament winding molding apparatus, in particular, a mandrel for winding a thread impregnated with a resin,
The present invention relates to a filament winding molding apparatus having an improved operation of exchanging a full winding mandrel with an empty mandrel and a method of using the same.

[0002]

2. Description of the Related Art In a conventional filament winding molding apparatus, most of the operations (thread switching) for switching a yarn from a fully wound mandrel to an empty mandrel rely on manpower. For example, after winding the yarn on the mandrel, the yarn connected to the mandrel is cut (manually) between the mandrel and the yarn traverse means, and the cut yarn slips through the traverse means to the creel side. The mandrel, which has been wound up, is removed from the chuck and, instead, an empty mandrel is chucked (usually automatic) to traverse the cut yarn. I removed it from a part of the means and fixed it to a new empty mandrel (manual), and then started the next winding.

[0003]

However, the thread switching in such a conventional filament winding molding apparatus has the following problems. (1) First, if the number of mandrels is large, it takes a long time for the manual preparation work, and the operating rate of the apparatus is reduced accordingly. (2) Further, when the yarn is tied to a new empty mandrel, the mandrel may be rotated, which may result in an unsafe work. (3) Further, since the yarn impregnated with the resin is directly handled, there is a problem that the hands and the like are soiled.

The present invention pays attention to such problems of the conventional apparatus and work, and automatically transfers the yarns succeeding the wound mandrel to a new empty mandrel without relying on manpower. Moreover, even when the number of mandrels is large, the filament winding molding apparatus can be transferred substantially simultaneously in a short time, the operation rate can be improved, and the safety is extremely high, and Its purpose is to provide a method of using the same.

[0005]

The filament winding molding apparatus of the present invention for this purpose is formed by converging a creel stand for holding a plurality of bobbins and a plurality of filaments supplied from the bobbin of the creel stand. Resin impregnated portion for impregnating a yarn with a synthetic resin, a mandrel for winding the yarn impregnated with the synthetic resin, a pair of chucking members for detachably gripping both ends of the mandrel, and a pair of chuckings. A bearing for rotatably supporting each of the members, and a winding portion of the yarn having a driving means for driving at least one chucking member of the pair of chucking members, and the axial direction of the mandrel, Filament winding molding provided with a traverse section for traversing a yarn impregnated with a synthetic resin (A) a waist drum around which the yarn is temporarily wound is provided between one of the chucking members of the pair of chucking members and the bearing, and (b) the chucking member and the waist. A space is provided between the drums, and (c) a cutting means for cutting a yarn that is temporarily wound around the waist drum and extends between the waist drum and the mandrel in the vicinity of the waist drum, It is configured so that it can enter and leave the space.

In the filament winding molding apparatus, it is preferable that a driving means for driving the waist drum is provided in addition to a driving means for driving the chucking member.

Further, in the method of using the filament winding molding apparatus according to the present invention, after the yarn from the resin impregnated portion is fully wound on the mandrel, the yarn on the fully wound mandrel is traversed by the traverse means. On the waist drum, after winding the yarn on the waist drum, by cutting the yarn extending between the full-winding mandrel and the waist drum by the cutting means, once the resin The yarn from the impregnation section is transferred onto the waist drum, the full-winding mandrel is doffed from the pair of chucking members, and then the empty mandrel is donned to the pair of chucking members to drive the driving means. While traversing, the traverse means located on the waist drum is traversed in the empty mandrel direction. The Rukoto comprises a method characterized by multiplying the yarn the yarn on the waist drum to the end of the empty mandrel.

[0008]

In such a filament winding molding apparatus, the yarn from the resin-impregnated portion on the fully wound mandrel which has been fully wound is temporarily guided by the traverse means to the waist drum. After being wound on the drum and the yarn between the full winding mandrel and the waist drum is cut by the cutting means, the full winding mandrel is doffed from the chucking member. Then, after a new empty mandrel is chucked, by traversing the traverse means located on the waist drum while rotating the empty mandrel in the empty mandrel direction, the empty mandrel from the resin impregnated portion is moved. The thread is threaded.

[0009] These series of operations can be automatically performed without any manual operation, and even if the number of mandrels is large, it is possible to perform the operations all at once by the automatic operation. Since thread switching can be performed efficiently in time, and no human labor is required, there is no work safety problem. In addition, the problem of dirty hands is eliminated.
