Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an SMC (Sheet Molding Compound) sheet which is folded in a container in a container and stored.

[0002]

[Prior art]

 SMC is composed of a thermosetting resin composition containing a glass fiber cut material such as chopped strands as a reinforcing material, and a thickened sheet sandwiched between a pair of separate films. A molded product can be obtained simply by placing it in a mold, pressing and heating.

[0003] The SMC is a sheet (SMC sheet) that is folded in a zigzag form, stacked, stored in a container, and transported to a molding factory in that state. In the container, the stacked SMC sheets are shifted in the width direction of the SMC sheets, and the lower part of the stacked SMC sheets is turned upward, and the stacked SMC sheets are placed on top of the turned SMC sheets. The SMC sheet cannot be pulled out properly at the molding plant where it is being transported, and the SMC sheet will be pulled and torn off if it is forcibly pulled out. There was a problem.

Therefore, in order to prevent such collapse of the load, a method of storing the sheet in a container suitable for the width of the SMC sheet has conventionally been adopted.

[0005]

[Problems to be solved by the invention]

 However, in the above-described method, since there are a plurality of types of SMCs having different sheet widths, it is necessary to prepare a corresponding number of containers, which has a problem that a huge cost is required.

Accordingly, an object of the present invention is to provide an SMC sheet container housing that can prevent the collapse of a load generated when the container storing the SMC sheet is carried by simple means at a low cost.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, according to the present invention, in an SMC container storage body in which SMC sheets are folded in a container and stacked and stored, a spacer is disposed on at least one of a gap between the container inner wall and the side surface of the SMC sheet. An object of the present invention is to provide an SMC container storage body characterized in that:

According to the present invention, since the spacer is disposed in the gap between the inner wall of the container and the side surface of the SMC sheet, the displacement of the stacked SMC sheets in the container due to the vibration when the SMC container is transported is generated. The SMC sheet can be prevented from being unable to be pulled out due to collapse of the load. Also, there is no need to prepare containers of various sizes according to the width of the SMC sheet, so that equipment costs can be reduced.

In the present invention, the spacer is preferably made of a resin foam, plastic, paper, or rubber, and more preferably made of a foamed polystyrene covered with a thermoplastic resin film. These materials have the advantage that they are relatively lightweight, have the required strength, and have low material costs.

[0010] Further, the height of the spacer is not less than the height of the stacked SMC sheets and not more than the depth of the container, and the thickness of the spacer is smaller than the gap formed on both sides of the SMC sheet. Preferably, the total thickness is 0 to 60 mm, and the width of the spacer is 15 to 80% of the length of the container. By setting the height, thickness, and width of the spacer within the above ranges, the collapse of the load of the SMC sheet in the container can be more reliably prevented.

[0011] Further, the spacers are disposed on both sides of the inner wall of the container located on the opposite surface in the width direction of the SMC sheet, and the interval between the spacers is gradually increased upward in the height direction of the container. It is preferable to form such a shape. According to this, when storing the SMC sheet in the container, the SMC sheet can be stored more smoothly without hitting the upper ends of the spacers arranged on both sides.

Further, it is preferable that the spacer is fixed to the inner wall of the container with an adhesive tape. According to this, when the width of the SMC sheet is changed, it is possible to easily replace the spacer by peeling off the adhesive tape.

[0013]

[Embodiment of the invention]

 1 to 3 show one embodiment of the container housing of the SMC according to the present invention. FIG. 1 is a perspective view showing a state in which the SMC is stored in a container, FIG. 2 is a plan sectional view of a container storage of the SMC, and FIG. 3 is a side view of the container storage.

The container housing 1 of the SMC of the present invention includes a container 2, an SMC sheet 3 stored in the container 2, and a plate disposed between an inner wall of the container 2 and a side surface of the SMC sheet 3. And spacers 4 in a shape of a circle.

The container 2 has an open upper surface, and a lid 5 (see FIG. 3) is placed on the upper surface. Spacers 4 are detachably attached to both sides of the inner wall of the container 2 in the width direction of the SMC sheet 3 by attaching means (not shown), for example, an adhesive tape.

As shown in FIG. 1, the SMC sheet 3 is continuously sent out from the last step of the SMC sheet manufacturing apparatus (not shown), and is fed into the container 2 by a supply device 10 installed above the container 2. Is stored. At this time, the supply device 10 swings in the direction of arrow F in FIG. 1 to fold the SMC sheet 3 in a zigzag manner and stack it in the container 2. Then, both sides of the SMC sheet 3 are guided by the spacers 4, and the SMC sheets 3 are stacked up and down without shifting in the width direction. After the SMC sheet 3 is stored in the container 2 in this manner, the lid 5 is put on the container, so that the SMC container storage body 1 of the present invention can be obtained.

Here, the material of the spacer 4 is not particularly limited as long as it has a certain degree of strength, but plastic, paper, or rubber is preferable, and more preferably, it is rigid for its light weight. It is a resin foam, and among them, Styrofoam is more preferably inexpensive and easy to process. However, when the spacer 4 is made of a material that is attacked by the styrene monomer in the SMC, such as styrene foam, it is necessary to cover the spacer 4 with a thermoplastic resin film such as polyethylene or polypropylene. In addition, examples of the material that requires coating include acrylic resin, polyvinyl chloride, and the like, in addition to styrene foam.

Next, preferred dimensions of the spacer 4 will be described with reference to FIGS. 2 and 3. First, as shown in FIG. 3, the height H ₁ of the spacer 4 is determined by the lamination height H of the SMC sheet 3. Preferably, it is not less than _{2 and not} more than the depth D of the container 2. If the height H ₁ of the spacer 4 is lower than the stacking height H ₂ of the SMC sheets 3, the SMC sheets 3 stacked above the spacers 4 are undesirably collapsed. If the height is too high, the spacer 4 protrudes from the opening of the container 2 and the lid 5 cannot be closed.

As shown in FIG. 2, the thickness T of the spacer is obtained by calculating the total thickness (2 × T) of the spacer 4 and the width W _{3 of the} SMC sheet from the width W ₂ between the inner walls of the container 2. It is preferable that the thickness is such that the drawn length, that is, the total length of the gaps R ₁ and R ₂ on both sides of the SMC sheet 3 is 0 to 60 mm. If the total length of the gaps R ₁ and R ₂ is less than 0 mm, the SMC sheet cannot enter, and if it exceeds 60 mm, the collapse of the load is apt to occur, which is not preferable. The width W ₃ of the SMC sheet refers to the width of the resin portion containing a glass fiber, the portion of only the separate film which extends on both sides has a width that does not contain.

Further, the width W _{1 of the} spacer 4 is preferably 15 to 80% of the length L of the container 2. If the width W _{1 of the} spacer 4 is less than 15% of the length L of the container 2, the displacement of the stacked SMC sheets 3 cannot be completely suppressed, causing collapse of the load. When it is folded in the inside 2, it is not preferable because the folded portion hits the side of the spacer 4 and the like, and the folding cannot be performed well.

The SMC container housing 1 thus obtained has spacers 4 on both sides of the inner wall of the container 2 facing the width direction of the SMC sheet 3, so that the gaps R on both sides of the SMC sheet 3 are provided. _Since the sum of ₁ and R ₂ is 60 mm or less, the displacement of the SMC sheet 3 in the width direction is suppressed, the collapse of the load can be prevented, and the disadvantage that the SMC sheet 3 cannot be pulled out of the container 2 can be avoided. Can be.

In addition, some spacers 4 are prepared according to the size of the container 2 and the width and the stacking height of the SMC sheet 3, and the spacer 4 is selected according to the SMC sheet 3 to be applied. By mounting the SMC sheet 3 on the inner wall of the container 2 by using the same container 2, it becomes possible to store SMC sheets 3 of various sizes.

For example, in the case of a container ₂ having a container width W ₂ of 1300 mm, a length L of 1000 mm, and a depth D of 900 mm, the SMC sheet 3 having a sheet width from 700 mm to 1200 mm can be obtained by using various spacers 4. Could be stored without collapse.

FIG. 4 shows another embodiment of the container housing of the SMC according to the present invention. In addition, the same reference numerals are given to substantially the same portions as those in the embodiment of FIGS. 1 to 3, and description thereof will be omitted. In this container housing 11, the spacer 4 is detachably attached to only one of the inner walls of the container 2 facing in the width direction of the SMC sheet 3 stored in the container 2. In this case, the length and width of the spacer 4 are the same as those in the above embodiment, but the thickness is processed to about twice the thickness of the above embodiment, or Two spacers 3 having a thickness are used in an overlapping manner.

FIG. 5 shows another embodiment of the container housing of the SMC according to the present invention. In addition, the same reference numerals are given to substantially the same parts as those in the embodiment of FIGS. In the container housing 21, spacers 40 are respectively arranged on both sides of the inner wall of the container 2 facing the width direction of the SMC sheet 3. The spacer 40 has a tapered shape as viewed from the thickness direction so that the interval between the spacers 40 increases as it goes upward. That is, the spacer 40 is formed so that the thickness thereof becomes gradually thinner upward, and has an inclined shape such that inner side surfaces located on both sides in the width direction of the SMC sheet 3 open upward.

Therefore, in the container storage body 21, since the interval between the spacers 40 increases as going upward, when the SMC sheets 3 are folded in a zigzag manner, the SMC sheets 3 may be caught on the upper corners 40 a of the spacers 40. The SMC sheet 3 can be stored in the container 2 more smoothly.

[0027]

【Example】

The storage of SMC shown in Example 1 1-3, as the container 2, the width W ₂ is 13 300 mm, the length L is 1000 mm, the depth D was used as the 900 mm. As the spacer 4, Ri Do from polystyrene foam coated with polypropylene film, the width W ₁ is 200 mm, the thickness T is 120 mm, the height H ₁ is used as a 900 mm, the inner wall of the container 2 of the SMC sheet 3 width It was arranged on both sides facing in the direction. As the SMC sheet 3, the width W ₃ used as the 1000 mm, and zigzag in the container 2 the height H ₂ and stored stacked so that 900 mm. The container container thus obtained was covered with a lid 5, loaded on a 10-ton truck, and transported from Furukawa City, Ibaraki Prefecture to Hakata City, Fukuoka Prefecture. As a result, no cargo collapse occurred.

Comparative Example 1 A container container of SMC was prepared and transported in the same manner as in Example 1 except that no spacer was used. As a result, the SMC sheet stored in the container was greatly collapsed in the width direction.

From the above results, it can be seen that the arrangement of the spacers 4 in the container 2 can effectively prevent the collapse of the load on the SMC sheet 3.

[0030]

[Effect of the invention]

 As described above, according to the present invention, the occurrence of the displacement of the SMC sheets stacked in the container due to the vibration when the container housing of the SMC is carried can be suppressed by the spacer, and the collapse of the load can be prevented. Also, even if the container is the same, it is possible to accommodate various widths of SMC sheets simply by replacing the spacers, and it is not necessary to prepare containers of various sizes according to the width of the SMC sheets. Therefore, equipment costs can be reduced.
