Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt-shaped film forming apparatus used for processing a blister film for packaging foods and medicines and an embossed carrier tape having a storage recess for storing electronic parts.

[0002]

2. Description of the Related Art As a conventional general belt-shaped film forming apparatus, as shown in FIG. 7, a film F rolled into a roll is first fed by a feed roller 5 formed by an existing technique.
With this, the heater 6 is sent to the heating convex portions 1 and 2 having a built-in heater at a constant pitch to heat the heating portion K necessary for forming the embossed portion E as shown in FIG.

That is, in order to form one embossed portion E, the film F is first heated in the heating portion K1 shown in FIG. 7, and then is fed at a constant pitch P by the feed roller 5 in the heating portion K2. After being heated, the film F is heated in the heating part K3 by this repetition and then heated to the optimum moldable temperature (in FIG. 7, the heating step is described as heating three times, but is not limited to three times. Absent.).

The film F thus heated is
The feeding roller 5 further feeds it to the molding step at a constant pitch, and is sandwiched from above and below by the molding convex portion 3 and the molding concave portion 4 shown in FIG. 7 to form the embossed portion E shown in FIG. there were.

[0005]

However, in the embossing by such a conventional strip-shaped film forming apparatus, the heating section K has the heating projections 1 and 2 shown in FIG. 7 as shown in FIG.
Therefore, heating is repeated a plurality of times to heat up to the moldable temperature, and therefore, once the film F is charged, the film must be continuously molded until the material finishes, and there is a problem that it is impossible to stop halfway.

Further, the heating convex portions 1 and 2 are required for a plurality of steps, and there is a problem that it is difficult to control the temperature.

Further, as shown in FIG. 9, the embossed portion E has a taping device for inserting the product S into the embossed portion E in the next step and for joining the top tape T for the purpose of preventing the product S from falling. Although it is necessary, since the conventional strip-shaped film forming apparatus cannot be operated intermittently as described above, the formed embossed carrier tape requires a take-up device and has a problem that it cannot be in-line with the taping device.

[0008]

In order to solve the above-mentioned problems, the strip-shaped film forming apparatus of the present invention uses one heating step in the heating section for heating the forming section of the strip-shaped film in advance.
It is configured to have only steps.

[0009]

As a result, the temperature of the heating section can be further stabilized, and when the apparatus is stopped, the heated strip-shaped film is always sent to the next step, and when the molding is completed, the operation can be stopped intermittently. Inline with the taping device can be easily realized.

[0010]

An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an overall view of the strip-shaped film forming apparatus according to the embodiment, and a film F formed by this apparatus is shown.
2 is shown in FIG. 3 and 4 are continuous molding state diagrams in this apparatus, FIG. 5 is a stop state diagram, and FIG. 6 is a restart state diagram after the stop.

First, the film F wound as shown in FIG. 1 is fed into the apparatus by a feed roller 5 according to an existing technique, and heating convex portions 7 and 8 having a heater 9 built therein are used to heat the heating portion shown in FIG. Heat K. At that time, since the heater 9 controls the temperature in only one step, the temperature can be controlled more stably than the conventional heating in a plurality of steps, and heating can be performed up to a predetermined moldable temperature in only one step.

As shown in FIG. 3, the heated film F is sent to the forming step by the feed roller 5, and the heating part K is placed at a position where the forming convex part 10 is arranged on the upper part and the forming concave part 11 is arranged on the lower part. Next, as shown in FIG. 4, the heating portion K is sandwiched between the molding convex portion 10 and the molding concave portion 11 and molded into a predetermined shape. At the same time, in the heating step, the heating convex portions 7 and 8 heat the heating portion K for molding in the next shot. By repeating the operation of FIGS. 3 and 4 as described above, a continuous embossed carrier tape is formed.

Next, the intermittent operation in the strip-shaped film forming apparatus of this embodiment will be described. First, in the continuous forming operation by the repeating operation of FIGS. 3 and 4, when it is necessary to stop the operation of the strip-shaped film forming apparatus of the embodiment due to the stop of the taping machine in-line or other factors, As shown in FIG.
0 and the molding concave portion 11 perform only the molding operation, and the heating convex portions 7 and 8 do not perform the heating operation. When restarting further, as shown in FIG. 6, the forming operation by the forming convex portion 10 and the forming concave portion 11 is not performed, only the heating operation by the heating convex portions 7 and 8 is performed, and then the feed roller 5
By this, the heating section K is sent to the molding step and brought into the state shown in FIG. 3 to enable continuous molding operation.

[0014]

As described above, according to the strip-shaped film forming apparatus of the present invention, the number of heating steps is one, the temperature control is facilitated, and in-line production with a taping machine or another apparatus is performed. Therefore, the heating unit for controlling the temperature can be manufactured at low cost, the winding device can be omitted,
It has many advantages such as low equipment cost, replacement of the take-up reel and transportation work due to in-line construction, and economical production.
