Description

  The present invention relates to a protector for a product in which a long basic product such as a plastic film, a plastic sheet, or paper is wound around a core in a roll shape.

  Long basic products such as plastic films, plastic sheets and paper are rolled into a roll around a core to be commercialized. In addition, this roll product protects the end of the long base product from becoming dirty or damaged by attaching a “protector” to the end of the roll when transporting or storing it. In addition, for example, as shown in FIG. 1B, the roll product surface is prevented from directly touching the floor surface or the like by floating a predetermined height from the floor surface or the inner bottom surface of the packaging box.

  As this kind of protector for roll products, as proposed in Patent Document 1 and Patent Document 2, there are those in which a cylindrical support shaft is projected from the vicinity of the center of a rectangular side plate portion. This type of protector for roll products rolls by holding both ends of the roll product between the side plate portions of the pair of protectors and inserting the support shaft into the hollow hole of the core material (core) to support the roll product. It protects the side edges of the product. A roll product protected by such a protector for roll products is fastened with a packing band in a cross shape on the outside of both side plates, and is then tightly tightened, and then stored in a cardboard box or wrapped in a sheet. It is used for transportation and storage.

JP 2010-228805, abstract, representative diagram Japanese Patent No. 5131845, FIG.

  Patent Document 1 provides a protector for a roll product that can absorb the impact and prevent the protector from being damaged, and can detect that the impact has been applied, and the time when the impact has been applied. "Roll product protectors" have been proposed.

  As shown in FIG. 7, the roll product protector disclosed in Patent Document 1 is “in the roll product protector 1 having the side plate portion 2 and the support shaft 3 protruding from the center portion of the side plate portion 2, the side plate portion 2. The shock absorber 4 for absorbing the impact is provided on the outer periphery of the container, and if necessary, there is an impact display means such as an ink enclosed in a container that is torn when the impact is received or a clock that is stopped when the impact is received. It is considered that the above-mentioned purpose can be achieved.

  However, in the protector for roll products of Patent Document 1, as shown in FIG. 7, since a large number of ribs for reinforcing this remain exposed on one side, dust is not formed between these ribs. Once entered, it is considered very difficult to clean and remove. “Dust” easily adheres to the basic product itself such as plastic film and plastic sheet, and may damage the basic product itself. It cannot be used for products.

  Moreover, since it is thought that the size of the protector for roll products of this patent document 1 cannot be changed, if the size of the roll product is different, it is necessary to prepare a size corresponding to that. It is thought that it is difficult to reuse.

On the other hand, Patent Document 2 proposes a “roll protection panel” for the purpose of “providing a roll protection panel that has excellent self-standing stability during use and can suppress the stacking height when not in use”. As shown in FIG. 8, for example, this "roll protection panel"
“A roll protection board having a rectangular plate shape capable of covering the end face of the roll and having a groove-like or hole-like core material support part capable of supporting the end part of the core material of the roll, At the time of use, in the roll protection panel which is placed upright at both ends of the roll and holds the roll in a floating state and is stacked in the down position when not in use, the corners of the four corners of the roll protection panel A pair of corner posts that protrude from both corners located on the lower side in the standing posture to assist the roll protection panel independence, and the remaining corners of the roll protection plate are defined as a cross-sectional shape of the corner support A pair of corner cut portions are formed by cutting in the same or wider range, and the corner support columns are turned upward and the plurality of roll protection panels are alternately rotated 180 degrees and stacked when not in use. In this case, the corner struts in the lower roll protection board are accommodated in the side of the corner cut part in the upper roll protection board, and the upper and lower roll protection boards are arranged in a regular stacking position where the outer edges of the four sides coincide with each other. It can be placed in
Is.

  Similarly to the “roll product protector” of Patent Document 1, the “roll protection board” of Patent Document 2 has a large number of ribs for reinforcing it exposed on one surface as shown in FIG. It is considered that once dust enters between these ribs, it is considered very difficult to clean and remove, so the “roll protection panel” that is soiled by dust is the next roll product. Will not be usable for.

  In addition, since it is considered that the size of the “roll protection board” of this Patent Document 2 cannot be changed, if the size of the roll product is different, a size corresponding to that is separately prepared. It is considered necessary and difficult to reuse.

  In short, the “protector for roll products” and the “roll protector” proposed in Patent Documents 1 and 2 above are types of packaging materials for long basic products such as plastic films, plastic sheets, and paper. This is a so-called disposable “one-way product”.

  However, in recent years, “disposable” is no longer considered a virtue. Rather, the idea that “trash is a resource” has become common, so even for packaging materials, Improvements along the way are needed.

In other words, for the protector for roll products targeted by the present invention,
(1) To enable reuse (2) To increase versatility and facilitate standard alignment (3) Dust is difficult to adhere, and even if it adheres, there is an increasing demand for easy removal It is coming.

  Therefore, the present inventors have completed the present invention as a result of various studies on how to satisfy the above requirements (1) to (3) at the same time.

  That is, a first object of the present invention is to provide a protector for roll products which can be reused and can be highly versatile with a simple configuration.

  A second object of the present invention is to provide a protector for a roll product that can achieve the first object, can prevent dust from adhering, and can easily remove adhering dust and dirt.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the embodiments described later.
“A protector that protects at least one end of the roll product 20 by being attached to the end of the core 22 exposed at least at one end of the roll product 20 in which the long material 21 is wound on the core 22. 10 and
A protector body 11 having a hole 13 to which an end of the core 22 is attached;
Is attached to the outer periphery of the protector body 11, Bei example the outer frame 12 made of a plurality of by forming the outer shape of the protector 10,
The protector main body 11 is constituted by two main body shells 11A connected to each other, and each main body shell 11A is formed on a shell surface 11a whose outer surface is a smooth surface and an inner surface of the shell surface 11a. A protector 10 comprising a plurality of ribs 11b erected in the thickness direction of the protector 10 "
It is.

  The protector 10 protects at least one end portion of the roll product 20, and the end portion of the core 22 exposed at at least one end portion of the roll product 20 in which the long material 21 is wound on the core 22. As shown in FIG. 1, two pieces larger than the outer shape of the roll product 20 are prepared, and these are attached to both sides of the core 22 of the roll product 20 and used. It is common. In addition, when winding the elongate material 21 on it, the both ends are fixed to the chuck | zipper of a winding machine.

  The protector 10 includes a protector main body 11 having a hole 13 to which an end portion of a winding core 22 is attached, and a plurality of outer frame bodies 12 attached to the outer periphery of the protector main body 11. As shown in FIG. 1, it is attached to the end of the core 22 constituting the roll product 20 by a hole 13 formed at the center thereof. Various shapes of the protector main body 11 are conceivable. However, the protector main body 11 is symmetrical with respect to the center line of the hole 13 such as a square as shown in FIG. 2 or a true circle as shown in FIG. Therefore, the number of outer frame bodies 12 to be described next can be set to “2”, which is preferable.

  The outer frame 12 constituting the protector 10 forms the outer shape of the protector 10 by being attached to the outer periphery of the protector main body 11, and can easily be attached to the outer periphery of the protector main body 11. In order to do so, it is divided into a plurality of parts. In particular, when the outer shape of the protector body 11 is symmetrical with respect to the center line of the hole 13 such as a square as shown in FIG. 2 or a true circle as shown in FIG. The number of the frame bodies 12 can be not only “2” but also the same shape on the left and right.

  Further, as shown in FIG. 2A, these outer frame bodies 12 determine the outer shape of the protector 10 by attaching them to the outer periphery of the protector main body 11, and have different sizes. By preparing the protector 10, the size of the protector 10 itself can be changed to the size indicated by the solid line and the virtual line in FIG. 2A even if the protector body 11 is used in common. Is.

  In other words, in the protector 10 according to the first aspect, the protector body 11 itself can be reused for transporting and storing the next roll product 20, and the outer frame 12 is the size of the next roll product 20. By selecting an appropriate one, the next roll product 20 can be sufficiently protected. That is, when the roll product 20 having a different diameter is regularly transported to a certain place, the protector main body 11 of the protector 10 used before can be reused for the next use. The protector 10 has general versatility as a whole.

  In addition, about each outer shape frame 12, it returns to the place which attaches the protector 10 with the protector main body 11 (If it is going to carry the used protector 10 for a process, naturally the protector main body 11 and the outer shape frame 12 will be simultaneously. For example, when it is used next time, it can be used again. Needless to say, the outer frame 12 can be reused.

  If two protectors 10 having the same size and larger than the outer shape of the roll product 20 are prepared and used on both sides of the core 22 of the roll product 20 as shown in FIG. As shown in (b), not only the both ends of the roll product 20 are completely wrapped, but the side surface of the roll product 20 is supported by being floated by a predetermined dimension from the floor surface or the inner bottom surface of the box. As a result, the entire roll product 20 is protected by both protectors 10.

Therefore, the protector 10 according to the first aspect can be reused and has high versatility.

Also, the information on the protector 10, the flop protector body 11, Ru configuration Nashitea by two body shell 11A to be connected against each other.

In flop protector 10 of this, the protector body 11, which is constituted by two main shell 11A to be connected against each other, for each body shell 11A, for example, those formed as shown in FIG. 3 It is.

  In this way, if the protector main body 11 is constituted by two main body shells 11A that are connected to each other, a space can be secured between the main body shells 11A like a closed bivalve shell. Thus, the weight of the protector body 11 as a whole and the materials used can be reduced.

Accordingly, the protector 10 according to the first aspect, the second, except that exhibit the same kind of function, it has become as capable of reducing the weight and material.

Furthermore, erected this flop protector 10 information, each body shell 11A, a shell surface 11a outer surface is smooth surface, is formed on the inner surface of the shell surface 11a, in the thickness direction of the protector 10 Ru configuration Nashitea by a plurality of ribs 11b that.

In flop protector 10 of this configuration that the body shell 11A is, as shown in FIGS. 3 (a) ~ (c) , and the shell surface 11a, by a plurality of ribs 11b formed on the inner surface of the shell surface 11a It is.

  The shell surface 11a of each main body shell 11A has a smooth outer surface as shown in FIG. 2 and FIG. 3B, so that two main body shells 11A having such a shell surface 11a are brought into contact with each other. As a result of the integration, the protector 10 itself is completed as a whole with a smooth outer surface, and it is difficult for the outer surface to become dusty, accumulated, or dirty. Moreover, if the protector 10 has a smooth outer surface, even if dust or dirt adheres to the surface, the protector 10 can be easily washed away with washing water or the like.

  Moreover, since the shell surface 11a of each main body shell 11A is as shown to each (b) of FIG.2 and FIG.3, since the several rib 11b was standingly arranged in the thickness direction of the said protector 10 on the inner surface, The two main body shells 11A having such a shell surface 11a are brought into contact with each other and integrated, whereby each rib 11b is completed as being wrapped by the shell surface 11a. For this reason, the protector 10 as a whole has the rib 11b inside, and has the rigidity necessary for the “protector”, and is lightened.

Accordingly, the first aspect engagement Ru protector 10, the third, the other to exert the a same as function, prevent adhesion of dust can be, it has become a thing easy removal of attached dust and dirt It is.

And in order to solve the said subject, the means which the invention which concerns on Claim 2 took about the protector 10 of the said Claim 1 ,
“Equipped with the auxiliary mounting cylinder 14 that is inserted into the hole 13 from the outside, fitted into the end of the core 22 and locked to the outside of the hole 13 by the flange 14a”
It is.

The protector 10 according to the second aspect also includes an attachment auxiliary cylinder 14 used for attaching the protector 10 to the roll product 20, and the attachment auxiliary cylinder 14 is shown in FIGS. 5 (b) and 5 (c). It is like that shown in. That is, as shown in FIGS. 5B and 5C, the auxiliary mounting cylinder 14 is cylindrical, and is inserted from the outside into the hole 13 of the protector 10 so that the end of the winding core 22 is inserted. And is engaged with the outside of the hole 13 by a flange 14a integrally formed at one end.

  The cylindrical portion of the auxiliary mounting cylinder 14 and the flange 14a are formed so that the diameter thereof matches the outer shape and inner diameter of the core 22 of the roll product 20 as an object. At the same time, the outer shape of the flange 14a is This is determined according to the inner diameter of the hole 13 formed in the protector body 11. As a result, when fitting the auxiliary mounting cylinder 14 to the end of the winding core 22, the size of the cylindrical portion of the mounting auxiliary cylinder 14 is set so as to match the inner diameter or outer shape of the winding core 22 so as not to rattle. In addition, the gap between the auxiliary mounting cylinder 14 and the hole 13 on the protector body 11 side can be closed by the flange 14a.

Therefore, the protector 10 according to the second aspect exhibits the same function as that according to the first aspect, and can prevent rattling and generation of a gap between the protector 10 and the roll product 20.

As described above, in the present invention,
“A protector that protects at least one end of the roll product 20 by being attached to the end of the core 22 exposed at least at one end of the roll product 20 in which the long material 21 is wound on the core 22. 10 and
A protector body 11 having a hole 13 to which an end of the core 22 is attached;
Is attached to the outer periphery of the protector body 11, Bei example the outer frame 12 made of a plurality of by forming the outer shape of the protector 10,
The protector main body 11 is constituted by two main body shells 11A connected to each other, and each main body shell 11A is formed on a shell surface 11a whose outer surface is a smooth surface and an inner surface of the shell surface 11a. That it is constituted by a plurality of ribs 11b standing in the thickness direction of the protector 10 "
Therefore, the protector 10 for the roll product 20 that can be reused and has high versatility can be provided with a simple configuration (achievement of the first object). ) since there also prevent adhesion of dust can be, achieved in the deposited removal of dust can also provide a protector 10 easy rolled products for 20 (second object) Ru Nodea.

The mode which protects the edge part of the roll product 20 using the protector 10 which concerns on this invention is shown, (a) is a perspective view, (b) is a side view. An embodiment of the protector 10 is shown, in which (a) is a plan view when the components are integrated, and (b) is an exploded view showing a state in which the outer frame 12 is detached from the protector body 11. FIG. It shows an example of the main body shell 11A of the protector main body 11 constituting the protector 10, wherein (a) is an inner surface view, (b) is a cross-sectional view taken along line 1-1 in (a), (C) is sectional drawing which shows the other Example shown to (b). It shows an example of the outer frame 12 of the protector main body 11 constituting the protector 10, wherein (a) is a side view showing the inside and (b) is along the line 2-2 in (a). FIG. The protector 10 also provided with the attachment auxiliary cylinder 14 is shown, (a) is a top view, (b) is an enlarged side view of the attachment auxiliary cylinder 14, (c) is an enlarged vertical sectional view. An embodiment of the protector 10 is shown, in which (a) is a plan view when the components are integrated, and (b) is an exploded view showing a state in which the outer frame 12 is detached from the protector body 11. FIG. It is a top view which shows the technique shown by patent document 1. FIG. It is a disassembled perspective view which shows the technique shown by patent document 2. FIG.

  Next, the invention according to each claim configured as described above will be described with reference to the protector 10 according to the embodiment shown in the drawings. FIGS. The perspective view and side view of the state which attached the protector 10 which concerns on the Example shown to the both sides of the roll product 20 which wound the elongate material 21 to the core 22 using the edge part of the core 22. Is shown. In this case, the protector 10 uses two pieces larger than the outer shape of the side surface of the roll product 20, and as shown in FIG. I support it floating.

  As shown in FIG. 2, the protector 10 includes a protector body 11 mainly having a hole 13 and two outer frame bodies 12 attached to the outer periphery of the protector body 11. The protector body 11 and the outer frame 12 are integrally molded using a synthetic resin as a material. Of course, the protector 10 does not have to be formed of a synthetic resin. If possible, for example, the protector 10 may be formed by pressing and compacting wood.

  As shown in FIGS. 2 and 3, the protector body 11 according to the present embodiment is formed in a “rectangular shape” in plan view, but is formed in a “true circle” as shown in FIG. Even though it is not illustrated, it may be formed in another shape. In any case, when the outer shape of the protector main body 11 is a line target shape with respect to the center line of the hole 13 to be described later, as shown in FIGS. In addition, the number of the outer frame 12 can be made as small as two and the outer frame 12 can be easily manufactured and attached to the protector main body 11. This is because it can be applied to a single protector body 11 simply by manufacturing the two outer frame bodies 12 having the same shape. If the outer frame bodies 12 are faced opposite to each other, the outer periphery of the protector body 11 can be applied. This is because the two can be completely surrounded by the two outer frame bodies 12.

  Therefore, when the outer shape of the protector body 11 is a regular polygon having an even number of corners, such as the regular square, the outer frame 12 can be easily manufactured and attached to the protector body 11.

Further, the protector body 11 according to the present embodiment is prepared by preparing two body shells 11A shown in FIG. 3 and abutting them together. In this case, as shown in FIGS. 3A and 3B, each main body shell 11A includes a shell surface 11a whose outer surface is a smooth surface and a plurality of ribs 11b formed on the inner surface of the shell surface 11a. The ribs 11b may be inward so that they are brought into contact with each other and integrated. This is because the outer surface of the protector main body 11 becomes a smooth surface due to the outer surface of each shell surface 11a, and it is difficult for dust to adhere to it, and even if dust or dirt adheres, it can be easily washed away with water or the like. This is because it can be dropped.

  Further, with respect to the main body shell 11A, when the ribs 11b face each other and are integrated with each other, the ribs 11b are not only protected from dust and dirt by being covered with the shell surface 11a, A large number of spaces can be formed between the ribs 11b, and the amount of synthetic resin as a material can be reduced. Of course, it is needless to say that the ribs 11b ensure the rigidity required for the main body shell 11A or the protector main body 11 formed thereby.

  Furthermore, in the protector main body 11 of this embodiment, as shown to (b) of FIG. 2, the fitting flange 11c is formed in the outer periphery. In the case of this embodiment, the fitting flange 11c is formed as a portion that is one step thinner than other portions. When the outer frame 12 described later is attached, the surface of the outer frame 12 The surface of the protector body 11 is formed so as to be substantially the same surface. Moreover, in the fitting flange 11c of this embodiment, as shown in FIG. 2B, a plurality of locking recesses 11d are formed on the surface, and these locking recesses 11d This is a locking portion when 12 is attached.

  Of the two main shells 11A, the outer main shell 11A may be formed by forming support legs 15 at the outer corners as shown in FIG. 3C. . The support leg 15 corresponds to the “corner column” in the above-mentioned Patent Document 2, and if the roll product 20 is tilted and rolled so that they are attached to the ground, the end of the long material 21 is scratched or deformed. Thus, the roll product 20 can be moved without giving any.

  As shown in each of FIGS. 2 and 6B, each outer frame 12 is formed in a “U” shape or a “semicircular shape”, and two of the outer frame bodies 12 are arranged on the outer periphery of the protector body 11. When attached to the protector body 11, a similar outer shape larger than the protector body 11 is formed.

  For example, as shown in FIGS. 4A and 4B, each outer frame 12 according to the present embodiment is formed with a fitting groove 12a on the inside, and the fitting groove 12a has the above-described inside. The fitting flange 11c on the protector body 11 side is fitted. In addition, in the fitting groove 12a, as shown in FIG. 2 (protector 10), a locking projection that fits into a locking recess 11d formed in the fitting flange 11c on the protector body 11 side. 12b is formed, and these locking projections 12b are fitted into the locking recesses 11d when the outer frame 12 is completely attached to the outer periphery of the protector body 11, and each outer frame 12 Positioning with respect to the protector main body 11 and fixing at that position.

  As shown in FIGS. 1 to 3, a hole 13 is formed in the center of the protector body 11, and the end of the core 22 constituting the roll product 20 is formed in the hole 13. Thus, the protector 10 is positioned and attached to the roll product 20. Of course, the shape of the hole 13 is formed in accordance with the shape of the end portion of the core 22 so that the core 22 and the protector 10 can be integrated with as little gap as possible.

  This hole 13 is formed in each main body shell 11A when the protector main body 11 is formed by two main body shells 11A according to this embodiment, and the end of the winding core 22 is formed at the end of the protector main body 11. It is fixed to the protector 10 in the two holes 13 separated by the thickness of.

  On the other hand, FIG. 5 shows the protector 10 also including the auxiliary mounting cylinder 14. As shown in FIGS. 5B and 5C, the auxiliary mounting cylinder 14 has a flange 14a integrated at the outer end of the cylindrical portion, and a rotation stopper 14b is formed in the cylindrical portion. Is. In addition, in the attachment auxiliary cylinder 14 of the present embodiment, a plurality of protrusions are formed on the outer periphery of the cylindrical portion, and when the cylindrical portion is fitted in the end portion of the core 22, The gap is not generated between the winding core 22 and the auxiliary mounting cylinder 14.

  The attachment auxiliary cylinder 14 shown in FIG. 5 basically assumes that the cylindrical portion is attached to the outer end of the core 22 and the end of the core 22 in that case is assumed. It is the rotation stopper 14b that prevents the cylindrical portion from rotating. Accordingly, each detent 14b is formed in parallel with the axial direction of the core 22 as shown in FIGS. 5 (a) and 5 (c).

  As shown in FIG. 5 (a), the flange 14a of the auxiliary mounting cylinder 14 has an outer shape larger than the diameter of the hole 13 on the protector body 11 side. The gap that may occur around the core 22 is covered.

  The above embodiment is directed to the case where the outer shape of the protector main body 11 constituting the protector 10 is a regular square. However, the present invention relates to a true circular protector main body 11 as shown in FIG. Is also applicable. Also in this embodiment, two outer frame bodies 12 having the same semicircular arc shape are fitted to the fitting flange 11c of the protector body 11 with respect to the outer periphery of the perfect circle protector body 11, and are regular squares.
