Description

Continuous wrapping system of extruded aggregates {A CONTINUITY WRAPPING SYSTEM OF AGGREGATE}

The present invention relates to a continuous wrapping system of extruded aggregate, and more particularly, to improve the productivity of the product by arranging the wrapping device for film attachment on the production line of the synthetic resin aggregate that is continuously extruded from the molding machine It relates to a system configuration for.

In general, PVC aggregate produced by extrusion molding of synthetic resin has durability and at the same time has excellent airtightness and excellent soundproofing and waterproofing effect, but is mainly used in various aspects such as window frame construction, but the color of finished product is too monotonous, and Even if the paint is painted, the surface is smooth and not only difficult to paint, but also unnatural, which is insufficient to satisfy the desire of modern people to pursue high quality.

Therefore, in order to provide a subtle and natural appearance to the outer surface appearing when the window frame materials are bonded to each other, a wrapping operation is performed to attach the pattern film to the surface.

1 is a view showing a system arrangement state of the production process using such a lapping apparatus.

That is, as shown, the resin molding, that is, the aggregate that is continuously extruded from the molding machine 1, passes through the cooler 2 at low temperature, and its hardness is increased to harden the shape. By the transfer to the cut portion 4 side is cut to the appropriate size in the cut portion (4).

Then, the cut aggregates are laminated in the vacancy (5) by the operator and sequentially supplied into the lapping machine (6), at the same time the patterned film to which the adhesive is administered to one side is transferred to the film on the aggregate surface during the internal transfer process As it is attached to the aggregate is completed that the film is attached will be produced.

When the production of the aggregate is completed, each aggregate is combined to form a desired structure such as a window frame.

However, in the conventional lapping system, since the overall process is not continuously performed, such as cutting the aggregate to a predetermined length in advance and then introducing it into the lapping machine 6, productivity is lowered. Thus, each aggregate in which the lapping work of the film is cut beforehand Both ends of the aggregates are finished intermittently due to being intermittently made, so that the film is poorly attached and must be cut again by a predetermined length, and the aggregates are lost until actual construction due to the need for cutting again in the process of combining each aggregate. There was a problem that occurred.

On the other hand, in order to solve the above problems, the film is first wrapped by the extruded aggregate, and the lapping is completed by cutting the aggregate to a desired size, and the lapping state of the film is also well along the entire aggregate length, thereby preventing the loss of the aggregate. The continuous system configuration is preferable, but there is a difficulty in configuring such a system line with a conventional lapping apparatus.

That is, the molding machine 1 for extruding the aggregate has to produce various kinds of aggregates due to its characteristics, and thus the lapping point to which the film is attached is also changed. In the case of the conventional lapping machine 6, the attachment position of the film is Since it is fixed constantly, it is impossible to construct a continuous lapping system.

In addition, the film is applied to the adhesive to the surface to be attached in the transfer process for attachment to the aggregate and the drying process for the applied adhesive proceeds sequentially, the production rate is changed according to the size of the aggregate to be extruded In contrast, the drying time from the adhesive administration step to the film adhesion step is difficult to cope with changes in the curing time of the adhesive.

The present invention has been proposed to solve the above problems according to the prior art, a process for producing the final aggregate in which the film is wrapped from the extrusion molding process of the synthetic resin aggregate lapping system that can proceed continuously in one production line The purpose is to construct.

It is another object of the present invention to provide an aggregate transport system that can appropriately vary the lapping point of the film with respect to the type and production rate of aggregate to be extruded from the molding machine of the continuous lapping system.

The object is a molding machine for extruding a resin material into aggregate of a certain form; A cooler configured to cool the aggregate extruded from the molding machine to a low temperature to maintain a molded shape; A drawer for forcibly transferring the aggregate that has passed through the cooler; Wrapping machine for continuously attaching the film is printed on the surface of the aggregate guided through the drawer using a pressure roller; A cutter for cutting the aggregate taken out from the lapping machine at a predetermined interval while the film is attached; And a storage unit in which the cut aggregate is loaded; and can be achieved through a continuous lapping system characterized in that it is sequentially provided along a moving path of the aggregate.

In particular, in order for the lapping system to be applied to various types of extruded aggregate, a position variable stage for moving the aggregate conveyed by the internal transfer roller in the vertical direction and the left and right directions is configured; An adhesive applying part is provided for applying an adhesive to a film surface to be transported for attachment to the aggregate, wherein the adhesive applying part provides a wrapping machine in which a conveying member is configured to enable linear movement of a position along a conveying path of the film. desirable.

Meanwhile, referring to FIGS. 3 and 4, the apparatus configuration of the present invention lapping machine 40 enabling the continuous system is as follows.

First, as shown in FIG. 3, the transport roller 41a for guiding the aggregate 100 guided through the take-out machine 30 in the horizontal direction, the attachment position between the aggregate 100 and the film 42 being transferred Pressure rollers 41b installed in the rollers, winding rollers 41c in which a certain amount of film 42 is wound, and guide rollers 41d, 41e, and 41f for stably preventing and guiding the film on the transport paths of other films. ) Were provided. The guide roller 41e of the middle of the guide rollers can be extended in the forward and backward directions by adjusting the roller shaft 41e ', so that the feeding path of the film 42 can be arbitrarily extended.

In the upper end of the apparatus, an adhesive applying portion 43 for applying an adhesive to the aggregate attaching surface of the film 42 to which the wound state is released from the winding roller 41c is disposed, and thus the lower bearing, which is an integrally coupled transfer member, is disposed. (43 ') is installed to allow a linear movement in a certain section along the transport path of the film, and drying chamber along the transport path of the film 42 in order to prevent the coated adhesive from curing during the film transport process. As the 44 is configured, hot air is injected from the heating part 45 installed at one end thereof.

And both sides of the transport roller 41a, as shown in Figure 4, the guider 46 for preventing the separation of the aggregate 100 during the transport process is fixed to the roller base 47, the roller base 47 The left and right adjustment handles 48 and the operating shaft 49 are coupled to the front and rear ends thereof, respectively, and the engaging member 51 screwed at the middle of the operating shaft 49 is connected to the roller base 47. It is fixedly installed to form an integral structure such that the structure forms a left / right position adjusting member that can change the film lapping point on the aggregate surface.

In addition, the flange 52 is extended to the left and right sides to the operation shaft 49, which is configured at the front and rear ends of the wrapping machine 40, respectively, the upper and lower adjustment lever 53 is rotatable to the flange (52). In the coupled state, the lower end is screwed to the base side portion 54 to configure the up / down position adjusting member of the aggregate.

Reference numeral 55 in the drawing represents a support shaft for supporting the film feed section.

As described above, the operation and effect of the present invention in which the overall system configuration is made will be described.

Aggregate 100 that is continuously extruded into various shapes such as window frames from the molding machine 10 into which the synthetic resin is injected is cured while passing through the low temperature water-cooled cooler 20 to prevent deformation of the shape. Aggregate 100 to be processed is continuously taken into the wrapping machine 40 while being taken out continuously by the rotational force of the take-out machine (30).

In the lapping machine 40, the aggregate 100 is transferred by the transfer roller 41a and the film 42 wound on the winding roller 41c is transferred at the same speed, and the application and drying process of the adhesive is performed. After being carried out, the pressure roller 41b is attached to a predetermined lapping portion of the surface of the aggregate 100, and the aggregate 100, which is completed such a lapping operation, is cut to a size suitable for construction in the cutter 50 and then stored. By being loaded on the part 60, the finished aggregate having a beautiful appearance can be produced continuously.

On the other hand, in the molding machine 10 of the present embodiment, various types of aggregates 100 are extruded, and as the production speed is changed according to the size of the aggregates 100, the lapping machine 40 is illustrated in FIG. 5. As described above, by moving the adhesive applying portion 43 in the horizontal direction to position it in place, it is possible to vary the timing of applying the adhesive to the film 42 surface. This makes it possible to appropriately adjust the drying time to prevent the applied adhesive from curing while the film is being transferred. It is preferable to move the adhesive dispensing position according to the transfer speed of the aggregate 100 to an optimal position by displaying a scale on the movement path of the adhesive applying unit 43.

In addition, in order to further increase the movement path of the adhesive-coated film 42 in addition to adjusting the position of the adhesive applying part 43, the position of the roller shaft 41e 'is adjusted to adjust the guide roller 41e. By further protruding to the rear side, it is possible to adjust the path until the film 42 is pressed against the surface of the aggregate 100.

And, according to the change in the aggregate shape (width, height, etc.) in the lapping machine 40 of the present invention so that the lapping point of the aggregate 100 to be transported by moving the transfer roller structure in the vertical or horizontal direction can be easily made. do.

That is, the operation of the present embodiment for moving the aggregate 100, which is guided into the lapping machine 40 in the left and right directions, to vary the film lapping point to the aggregate surface, the operator first moves the left / right adjustment handle 48 When rotating the operating shaft 49 is a screw thread formed along the outer circumferential surface, the engaging base 51 which is screwed to the outer circumferential surface of the operating shaft 49 is horizontally moved, the roller base is fixed integrally ( By moving the 47 and the guider 46 and the transport roller 41a together, it can be seen that the lapping point of the aggregate 100 to which the film 42 is to be attached is changed in the horizontal direction as shown in FIG. 7. This can be achieved by appropriately changing the position by sequentially operating the left / right adjustment handle 48 formed on the front and rear ends of the wrapping machine 40, respectively.

In addition, in this embodiment, in order to move the position of the transfer roller 41a in the up and down direction according to the height of the aggregate 100, the operator has to move the upper / lower adjustment lever 53 which is screwed to the base side 54. When rotated, the flange 52, which is integrally fixed while the lever is raised or lowered, flows together, and thus, the integral structure including the operating shaft 49 and the roller base 47 flows together in an up and down direction, thereby transferring the rollers. The position of 41b) can be raised or lowered. Since the four upper and lower adjustment levers 53 are installed at both the front and rear ends of the lapping machine 40, each of the levers must be adjusted to the same height so that the overall leveling can be performed.

Therefore, the present invention is provided with a wrapping machine 40 that can be appropriately variable according to the type and production speed of the aggregate and the lapping point of the adhesive administration position and aggregate surface as described above, the process of extrusion molding various types of aggregate It can be seen that the production of the product through the lapping and cutting process of the film is possible continuously on one manufacturing line.

In particular, since the film lapping of the aggregate surface is performed first, the cutting process is performed to a suitable size for the construction, thereby further improving productivity and work efficiency, and the lapping of the film is stable and uniform, resulting in cutting the conventional aggregate. The waste factor can be greatly reduced.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the lapping apparatus of the present invention may be variously modified and implemented by those skilled in the art.

For example, in the above embodiment, as shown in FIG. 5 in a state where the position of the drying chamber 44 is fixed and the upper end is opened, the position of the adhesive applying part 43 may be moved to the interior of the drying chamber 44. As shown in another embodiment in FIG. 6, the adhesive is fixed by fixing the adhesive applying part 43 to the end in a state where the drying chamber 44 ′ is provided in the form of a wrinkle membrane such as a bellows in which the inner space is sealed. As the application portion 43 is moved, the internal volume of the drying chamber 44 ′ may be configured to be variable.

However, such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments shall fall within the appended claims of the present invention.

In the continuous lapping system of the present invention as described above, the production of the product through the film lapping and cutting process of the aggregate surface from the molding of the aggregate to be extruded, and thus the product productivity and work The effect can be further improved efficiency.

In particular, as the type and production speed of the aggregate extruded from the molding machine is changed, it provides a configuration that can appropriately change the adhesive dispensing position and the aggregate surface lapping point in the lapping machine, the system compatibility according to the characteristics of the extrusion product To maximize.
