Description

[Detailed Description of the Invention] <Industrial Application Field> In order to attach a cylindrical synthetic resin film whose inner side is tightly adhered to a container, the synthetic resin film can be easily attached to the container by breaking the adhesion of the synthetic resin film. This figure relates to a diagram of installing a synthetic resin film on a container that is spread out as shown in FIG.

<Prior art and its problems> Conventionally, when liquids are stored and sold in containers, particularly bottle-shaped containers, it has been common practice to print the name, efficacy, manufacturer's name or product name of the liquid directly on the container. Since doing so would increase the cost, methods such as printing on a separate synthetic resin film and gluing or attaching it to the container were used.In this case, in order to simplify the work, This synthetic resin film was formed into a cylindrical shape, attached to a container, and hot air was applied from the outer periphery of the film to shrink it and make it adhere tightly to the container.

By the way, such synthetic resin films are physically formed into a cylindrical shape, but for printing and cutting reasons, they are sent as if they were two sheets stuck together, and they are cut into a certain length. The plastic film must be cut into a cylindrical shape and then opened into a cylindrical shape when it is attached to a container.However, in conventional synthetic resin film attachment devices for containers, when opening into a cylindrical shape like this, it does not open completely. , opening 1. In this case, the synthetic resin film was placed on top of the upright container, and the synthetic resin film was dabbed little by little.However, with this mounting method, the synthetic resin film was extremely thin and flexible. Therefore, it is difficult to install the product smoothly, and the synthetic resin film may break due to small taps, and if the container has a stepped shape, the synthetic resin film may get caught in the step. There are also many examples of failures during work.

Means for Solving the Problems> Therefore, the present invention provides a suction type temporary expansion device formed to be slidable, a rotary guide body having a sharp tip, and two components.
The pieces are movable in the approaching and separating direction and the front-back direction, and a suction device with a recess formed in the joint surface of the two pieces that roughly corresponds to the shape of the outer circumferential surface of the container is installed in a series to completely remove the synthetic resin film. The container can be opened easily and smoothly into a container.

Embodiment Next, an embodiment of the apparatus for attaching a synthetic resin film to a container according to the present invention will be described based on FIG. is provided with auxiliary suction devices 2 and 2' on the upper and lower sides, and in particular, the upper auxiliary suction device 2' moves up and down in the upward r direction, and
The entire structure is movable in the front-rear direction. Reference numeral 3 denotes a rotary guide body having a sharp tip, and this rotary guide body 3 protrudes radially from a central rotary shaft 4, and is configured to be rotatable in a plane by the rotary shaft 4. ing. 5 is a main suction device, and this main suction device 5 is also composed of two pieces of suction device 6 on the left and right, and these two pieces of suction device 6 are formed so as to be movable in the direction toward and away from each other and in the front and rear directions. . A recess 8 approximately corresponding to the shape of the outer peripheral surface of the container 7 is formed on the joint surface of these two pieces of the suction device 6.
It is formed. This recess 8 is formed to correspond to the outer peripheral surface shape of the container 7, so if the container 7 is cylindrical, the recess 8 is also circular (as in this example).
Furthermore, if the container 7 has a rectangular tube shape, the recess 8 is also formed in a rectangular shape. Further, each of the two pieces of the suction device 6 is formed hollow, and the recess 8 is provided with a large number of small holes. In addition, 9 is a synthetic resin film.

What is shown in FIG. 2 shows the other side of the synthetic resin film mounting device for containers according to the present invention, and the first
In the case shown in the figure, the containers 7 are arranged horizontally and the synthetic resin film 9 is attached, whereas in the case shown in Fig. 2, the containers 7 are arranged vertically and the synthetic resin film 9 is attached.
It is to be worn. The only difference between the embodiment shown in FIG. 2 and the embodiment shown in FIG. 1 is that the single-rotation guide body 3 rotates in the vertical direction and the main suction device 5 moves in the vertical direction. However, there is no such thing, so the numbers used in FIG. 2 are the same as those in FIG. 1.

Function> Of the auxiliary suction devices 2, 2', the upper auxiliary suction device 212' is raised, and the upper and lower auxiliary suction devices 2.2' are caused to fall, and during this time the synthetic resin is Send film 9. And the upper auxiliary suction device 2,
2' is lowered, this auxiliary suction device ff12.2' is operated for suction, and the upper auxiliary suction device 212' is raised again. Then, the synthetic resin film 9 will open up and down. In this state, the synthetic resin film 9 is moved forward and guided to the rotary guide body 3, and when the synthetic resin film 9 is attached to the rotary guide body 3, the auxiliary suction device 2.
Stop the suction operation of 2'. Then, the synthetic resin film 9
leaves the auxiliary suction device 2.2' and transfers to this rotary guide body 3. Next, the auxiliary suction device 2.2' is moved backward, the rotary guide body 3 is rotated, and the main suction device g! Turn to 15 bias.

The main suction device 5 opens the rotary guide body 3 in a state in which the two pieces of suction device 6 constituting the main suction device 5 are opened in the vertical direction.
When it reaches the position of the synthetic resin film 9 on the rotary guide body 3, the movement is stopped and the two pieces of the suction device 6 are brought into close contact with each other to operate the suction operation. Then, the synthetic resin film 9 is attached to the two pieces of the suction device 6.
It is brought into close contact with the recess 8 of. That is, since this recess 8 has the shape of the outer peripheral surface of the container 7, the synthetic resin film 9
will be opened into a cylindrical shape. In this state, the main suction device 5 is moved back and guided toward the container 7, and the container 7 is in the recess 8 of the two pieces of suction device d6, that is, it is adsorbed to the recess 8 and synthesized. Resin film 9
While the main suction device 5 is inside, the movement of the main suction device 5 is stopped, and the suction operation is also stopped. Then 1 synthetic resin film 9
is separated from the synthetic resin film 9, and the main suction device 5 is moved to the container 7.
When released from the container 7, the synthetic resin film 9 is attached to the container 7. This completes the attachment of the synthetic resin film 9 to the container 7, but since it is difficult to say that the synthetic resin film 9 will adhere tightly to the container 7, if hot air is applied to the outer periphery of the container 7 while the synthetic resin film 9 is attached, the synthetic resin film 9 will be removed. 9 contracts and comes into close contact with the container 7.

<Effects of the Invention> As described above, according to the apparatus for attaching a synthetic resin film to a container according to the present invention, since the main suction device is provided, the synthetic resin film 5 can be completely opened and the concave portion of the main suction device can be opened. Since it has the shape of the outer peripheral surface of the container, it has the effect that the synthetic resin film can be smoothly and easily attached to the container.
