Description

A roll forming apparatus for a sandwich panel pallet and a sandwich panel pallet manufactured by the apparatus TECHNICAL FIELD

The present invention relates to a roll forming apparatus for a sandwich panel pallet and a sandwich panel pallet manufactured by the apparatus. More specifically, the sandwich panel further improves leakage, dustproofing, and insulation performance while being freely adjustable in size and color. It relates to a roll forming apparatus for a pallet for use, and a pallet for sandwich panels manufactured by the apparatus.

In general, sandwich panels are integrated by filling a heat-insulating material and sound-absorbing material between two sheets of pallets formed by bending a metal iron plate in various forms having different heights and widths.

In the case of the sandwich panel, a variety of bends are formed in order to add aesthetics to the pallet. Usually, a pallet having a variety of bend patterns is formed by using a roll forming apparatus provided with a plurality of upper and lower pairs of forming rollers formed with bends. Molding.

The conventional roll forming apparatus is configured to continuously roll-form a sheet metal coil loaded on one uncoiler, and to process only a pallet having a predetermined width by a sheet steel coil produced to a certain standard. It is.

The conventional roll forming apparatus processes a pallet having a predetermined size having a width of about 1 m, forms them into a sandwich panel, and cuts them to a constant length to produce a finished sandwich panel, and attaches them to the frame using fixing screws. It is to be connected by fixing.

Therefore, a sandwich panel manufactured by a conventional roll forming apparatus is always made to be manufactured to the same standard, and has a limit that cannot be manufactured by expanding its width and producing a pallet having only a single color.

This limitation requires that a connection frame for connecting a single sandwich panel is essential when used as a partition, an interior wall or a partition of a building where sandwich panels manufactured using roll-formed pallets are used. The design aesthetics are deteriorated, such as the screws for fixing to the frame is exposed to the outside, and the problems arise that the installation of this sandwich panel requires a lot of time and professional personnel.

Accordingly, the present applicant has developed and solved the technology related to the "roll forming method and roll forming apparatus for a sandwich panel pallet," and has been patented as a registered patent 0906106.

However, in spite of the excellent effect of the registered patent, there is a need for improvement in the exterior part, that is, the painting part, and also the need to develop a more competitive sandwich panel with a more differentiated aesthetic in terms of waterproofing, soundproofing, dustproofing, and design. It has emerged.

For example, in the case of painting, it is usually requested by a painting factory to uniformly paint according to the design, so that at least two or more colors may be formed in the form of painting after the first painting.

In this case, the secondary coating must be applied to the other colors on the primary painted color, so the inconvenience of having to apply the coating multiple times in order to prevent the background color from shining, resulting in increased cost, lack of autonomy of color scheme, and the color cannot be changed freely. There was a downside.

In addition, due to such difficulties in painting, consumer complaints are increasing because it is difficult to meet rising costs and due dates.

In addition, two-tone, that is, when two colors are painted, the boundary between the two colors is not consistent, there was a disadvantage that the appearance quality falls.

In addition, when the sandwich panels are arranged vertically, the joints are inserted and connected in a bent state, so that there is a high risk of leakage through the accommodating groove part of the joint, and especially when used as a wall of a freezer, a storage warehouse, etc. Problems may arise.

Furthermore, when the sandwich panels are arranged horizontally long, deformation such as bending due to high wind pressure, such as strong wind, occurs, and the risk of leakage to the deformed portion also increases the wind resistance.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The roll forming apparatus of the sandwich panel pallet according to the present invention is a further improvement of the roll forming apparatus disclosed in the registered patent application No. 0906106, which the applicant has previously registered, and the concept of roll forming is the same.

That is, as shown in Figure 1, the roll forming apparatus of the pallet for sandwich panels according to the present invention includes three uncoilers, such as the lower uncoiler (U1), the upper uncoiler (U2), between them It is the sealing jammer U3 which is arrange | positioned.

At this time, the lower uncoiler (U1) and the upper uncoiler (U2) is uncoiled the lower iron plate (C1) and the upper iron plate (C2) to constitute a sandwich panel pallet, and the sealing material uncoiler (U3) Through the uncoiled sealing material (C3) to be interposed between these lower iron plate (C1) and the upper iron plate (C2).

Here, the uncoiler and the iron plate divided into upper and lower parts are merely for convenience of description and do not specify a location.

In addition, the members uncoiled through these uncoilers are subjected to a roll forming machine 10. The roll forming machine 10 is a known forming apparatus consisting of a plurality of roll combinations. It is a kind of molding machine which consists of a pair of upper and lower rolls so as to be suitable for bending at a predetermined angle.

In this case, the roll forming apparatus according to the present invention is characterized by further comprising a guide roll 13 as a roll set to guide the sealing material C3, unlike the roll forming apparatus disclosed in the pre-registered roll forming apparatus.

That is, the roll forming machine 10 includes an upper forming roll (formed as a pair of upper and lower, roll forming to have a predetermined shape as the upper steel plate passes between the pair) 11 and the lower forming roll 12 as before. However, the guide roll 13 is further installed between the upper forming roll 11 and the lower forming roll 12, in particular, the guide roll 13 is not intended to form, but simply to the sealing material (C3) to a constant tension Since it is only responsible for the guiding function, it is not necessary to have a pair of upper and lower ones.

In addition, such a roll forming machine 10 is to perform a roll forming process as shown in the example shown in Figures 3a to 4b, this part is the same as the contents disclosed in the registered patent registered by the applicant.

For example, as shown in FIGS. 3A to 3C, the bending angle θ of the upper steel plate C2 entering the upper forming roll 11 is formed while sequentially passing through the plurality of upper forming rolls 11. It will be bent almost vertically.

Through this process, as shown in Figure 3c, the upper plate (C2) is formed to have a receiving groove 20 of the '∩' shape.

On the other hand, the lower iron plate (C1) sequentially subjected to the lower forming roll 12 is formed through the same process, but in the case of the lower forming roll 12, the receiving groove of the upper plate 20 formed as shown in Figure 4a An end of the lower steel plate C1 is completely pressed to form the protrusion 22 so as to be correspondingly inserted into the 20.

Then, when passing through the coalescence roll 14 shown in Figures 1 and 4b to maintain the state in which the projection 22 of the lower iron plate (C1) is inserted into the receiving groove 20 of the upper iron plate (C2). Then, the final pressing while passing through the pressing roll 15 shown in Figure 1 and the lower iron plate (C1) and the upper iron plate (C2) having a different color for one sandwich panel for the seam groove 20 portion of the seam It will form a palette.

Since such a forming process is disclosed in detail in a registered patent registered by the present applicant, further detailed description will be omitted, and only core matters according to the present invention will be disclosed.

As shown in Figure 2a, the sandwich panel pallet according to the present invention is to be manufactured in a state where the joint portion is reinforced through the above-described roll forming apparatus.

That is, the protrusion 22 of the lower steel plate C1 roll-formed through the lower forming machine 12 is inserted into the receiving groove 20 of the upper steel plate C2 roll-formed through the upper forming machine 11. The projecting portion 22 is configured to engage and insert the sealing material C3 with the sealing material C3 disposed therebetween before being coalesced to improve sealing property.

Then, it will be in the state as (a) or (b) of FIG. 2A.

In this case, the sealing material (C3) is preferably a flexible material, such as rubber or synthetic resin having an adhesive, it is more preferable to apply the adhesive when using rubber.

In particular, when the sandwich panel is made, the receiving groove 20 is directed toward the inside of the panel, so that only the outer line is visible in the form of long lines.

And since the sealing material C3 is interposed like the illustration, there is no risk of water leakage, soundproofing and dustproofing improve, and above all, heat insulation improves.

At this time, the sealing material (C3) when the concave-convex (24) is formed on one side or both sides of both ends, the pressing force is increased when coalescing to provide better sealing properties.

In addition, the sealing material (C3) is smaller than the depth of the receiving groove 20, such as (a) of Figure 2a to wrap the upper end of the protrusion 22 to be less than 1/2 of the depth of the receiving groove (20) and It may be manufactured in the same form, or in some cases, may be disposed almost equal to the depth of the receiving groove 20 as shown in (b) of FIG.

In addition, in some cases, the waterproofing paint may be used as the sealing material C3, and the waterproofing paint locally has a predetermined thickness on the outer surface constituting the protrusion 22, that is, the surface facing the inner wall of the receiving groove 20. By coating so as to have a joint roll 14, the joint may be configured in a form as shown in FIG. 2A when the joint is formed, so as to obtain the same effect.

On the other hand, the sandwich panel has a length of 5 ~ 7m in some cases, in this case, the bending deformation in the longitudinal direction is likely to occur.

In particular, when the strong wind is blown because the reinforcing material is not embedded, the wind resistance is poor.

Therefore, in order to prevent this, the width of the sandwich panel can be narrowly arranged to be densely arranged, in which case the aesthetics are also reduced and the processing cost increases a lot.

In the present invention, the structure of the sandwich panel pallet can be improved in the form as shown in (a), (b) and (c) of FIG.

In this case, (a) is the case where the core material 26 is inserted, it can be simply configured by roll-forming in the state provided with the core material 26 at the time of processing the projecting portion 22 of the lower iron plate (C1).

That is, although not shown in the upper portion of the lower uncoiler (U1) in Figure 1 is provided with a separate core input equipment, it can be configured to roll-formed together when processing the protrusions (22).

Then, since the core material 26 is built in the longitudinal direction of the joint, wind pressure resistance is remarkably improved and bending deformation is prevented.

In addition, (b) is a case where the band member 28 is inserted, and can be comprised simply by roll-forming in the state provided with the band member 28 at the time of processing the protrusion part 22 of the lower steel plate C1. .

In this case, it is preferable that the strip member 28 has a substantially 'T' shape, and it is more preferable to form an uneven portion at the insertion end so as not to be easily detached after pressing.

In particular, in the case of the band member 28, as well as the strength reinforcing function, such as the core material 26, as well as completely hide the joint portion of the boundary line of different colors, the aesthetics are also improved, and a separate color is given to the band member 28 itself This gives the part another color, which further enhances the design, and further maximizes the waterproofness, soundproofing, dustproofness and insulation.

In addition, as in the case of (c), the U-shaped reinforcement 30 may be inserted so as to completely cover the outside of the upper steel plate C2. Does not give.

On the other hand, between the coalescence roll 14 and the pressure roll 15 disclosed in Figure 1 is further provided with a pressing means, the pressing means is a sealing member (C3) and the projection (inserted in the coalescing portion (F, Fig. 5)) It is for fixing so that 22) does not come out easily, It can be comprised by the local pressing roll 15a like (a) of FIG. 4C, and can also be comprised by the spot welding machine 15b like (b).

At this time, a part of the localized pressing roll 15a is locally formed with a processing protrusion (not shown) so that the sealing material C3 and the protrusion 22 inserted into the receiving groove 20 of the upper steel plate C2 are easily formed. In order to block them from being separated, they may be configured to have a firm fixability by pressing and pressing a portion of the lower bottom of the upper steel plate C2 in the assembled state.

In addition, the spot welding machine 15b may be used instead of the local pressing roll 15a as shown in FIG. 4C (b).

At this time, the spot welder 15b is also preferably disposed at the position of the first press roll at the position where the press roll 15 is to be installed. (C2) and the lower steel plate (C1) is welded to have a more firm fixing and at the same time the built-in portion is not easily escaped.

Furthermore, of course, these two cases can also be parallel.

On the other hand, as shown in Figure 5a, further provided with a pattern processing roll 16 in the direction orthogonal to the coalescing roll 14, the upper iron plate (C2) and the lower iron plate (C1) to form a coalescing portion (F) It can be configured to give a variety of designs 17.

At this time, the design 17 may be formed by the processing shape (17a) such as embossed or engraved pattern, patterns, letters, pictures, letters on the surface of the pattern processing roll 16, a pair of up and down on both sides The flat part P1 and P2 formed in the adjacent side of the coalescing part F of the upper iron plate C2 and the lower iron plate C1 by pressing the coalescence part F strongly by the patterned roll 16 provided with two sets. The various designs 17 are configured to be displayed on the lower surface of the image, that is, on the side exposed to the outside.

In this case, the design 17 is preferably a three-dimensional shape, the same processing corresponding to the other pattern processing roll 16, when the processing shape (17a) is embossed on any one of the pair of patterning roll (16) It is particularly preferable that the shapes are engraved so that they can be combined by mutual compression.

In addition, even in this case, by pressing the outer lower portion of the coalescing portion F through the local pressing roll 15a described in FIG. 4C to make the pressing portion Fa as shown in FIG.

When the processed pallet is assembled with the filler, a sandwich panel having a shape as shown in FIG. 5B can be configured.

In other words, the flat portion (P1, P2) in a state in which the various design 17 is produced in the state in which the coalescing portion (F) is embedded in the installation groove (H) of the filler (I) is a neat appearance as shown It is possible to provide, because the sealing portion (F) is provided with a sealing material (C3) to maximize the sealing properties.

This enhances the aesthetics and enhances the appearance.

In addition, when it is necessary to implement two or more colors on a single palette, when the boundary line of the painting is bent and compressed like the protrusion 22 as described above, the boundary line is precisely straightened and a neat appearance can be provided. Since the bent portion is buried into the filling material filled during the panel formation, it may be possible to realize a cleaner and more various colors without affecting the appearance quality at all.

More specifically, as described above, instead of using two sheets of paint coated in different colors, as shown in Figs. 6A to 6C, when two colors are painted on one sheet (palette), the paint is painted as shown. The boundary line L may not be straightened, which may reduce aesthetics.

In this case, by applying the method described so far, the coating boundary line L can be bent (formed), thereby eliminating it neatly.

For example, as shown in FIG. 6B, the paint boundary line L may be gradually formed to form the crimping portion L1, which may be performed in the same manner as the constricting protrusion 22 is formed as in FIG. 2A. Can be.

Then, the crimping portion (L1) is embedded in the filler (I) in the form as shown in Figure 6c to improve the aesthetics of the paint boundary line (L) is clear and straightened.

As such, the roll forming apparatus according to the present invention and the sandwich panel pallet manufactured therefrom are significantly improved in airtightness (sealing property) of the joint portion, that is, the coalescing portion (F), thereby maximizing waterproofing, soundproofing, dustproofing, and thermal insulation performance. In addition, since the strength in the longitudinal direction is reinforced by the core material 26, the belt member 28, the reinforcing material 30, etc. provided in this portion, the bending deformation is prevented, and thus the wind resistance is improved. .

In addition, the appearance quality and design are improved to increase purchasing power, make it easier to implement various colors, and to produce more point colors at the seam area, which enhances aesthetics, enhances strength, and provides excellent sealing properties. It also has the advantage of increasing the size of the panel.
