Abstract

PROBLEM TO BE SOLVED: To provide a protector for a roll product capable of prevent the damage of the protector by absorbing an impact and detecting the application of the impact and a time or the like when the impact is applied.SOLUTION: In a protector 1 for a roll product having a spindle 3 protruded from a side plate 2 and the center of the side plate 2, a buffer 4 for absorbing an impact is provided on an outer circumference of the side plate 2.

Description

  The present invention relates to a protector that is attached to both end surfaces of a roll product wound with a strip-shaped product such as a plastic film and protects the end surface and the peripheral surface of the roll product. The present invention relates to a roll product protector provided with means for absorbing the shock when the strong shock is applied, preventing the damage of the transported product by absorbing the shock, and further indicating that the shock has been applied.

Conventionally, when transporting and storing strip-shaped products such as plastic films, plastic sheets, paper, etc., these strip-shaped products are wound around a core material to form a roll product, and the roll product protector (simply simply In order to prevent the roll product from getting dirty or damaged during transportation or storage.
As this conventional protector P, as shown in FIG. 17, a cylindrical support shaft 3 projecting from the vicinity of the center of the rectangular side plate portion 2 can be cited. While sandwiched between the side plates of the protector P, the support shaft 3 is inserted into the hollow hole of the core material to support the roll product R, and if necessary, the packing band 6 is hung in a cross shape on the outside of the side plates 2. The whole is tightened and further stored in a cardboard box (not shown) or the like for transportation and storage (for example, Patent Document 1).

The roll product R has both end surfaces in close contact with the inner surface of the side plate portion 2 so that the roll product R is prevented from sliding out into a bamboo shoot shape, and the support shaft 3 is inserted into the hollow hole of the core material R1, thereby The product R is supported in a suspended shape so that the width surface of the product R does not contact the packing band 6 or the inner surface of the cardboard box, and is transported or stored so as not to be damaged.
However, if it is accidentally dropped during transportation or handling is poor, for example, as shown in FIG. 18, the support shaft 3 is broken at the location of the support shaft 3 and separated from the side plate portion 2, and as a result, Part of the width surface of the roll product R supported in a suspended manner by the support shaft 3 collides with the inner surface of the packing band or cardboard box, resulting in problems such as scratches or dirt, and the product value is remarkably increased. In some cases, it cannot be used as a product. Further, when the support shaft 3 is separated from the side plate portion 2, the packing band 6 is also loosened, and the end face of the roll product R is also damaged. Although FIG. 18 shows a case where one of the protectors is damaged, both protectors may be damaged.
Such a trouble is the same when the vicinity of the lower end portion of the side plate portion 2 is damaged.

Such a protector is designed with strength in consideration of the weight of the roll product R to be protected and the impact normally applied during transportation and storage. However, in order to reduce the weight of the protector and reduce the manufacturing cost, it is not possible to provide an excessive margin, and the protector is damaged due to impact in the hope that it will not be handled violently by the contractor during transportation. Is preventing. Therefore, if the protector is frequently damaged due to rough handling, throwing or dropping, encourage the contractor to improve or consider switching to another contractor if improvement is not expected. To prevent recurrence.
However, in the case of long-distance transportation by relaying a large number of transportation means, in reality, it is impossible to specify at which stage the breakage has occurred, and therefore it is practically difficult to promote improvement. In particular, when transporting overseas, there are many means of transport to relay, and when traveling through many countries and regions, the nationality, work concept, and morals vary, It is an important issue to know which country and region the trouble occurred in, and which trader was handling during the handling, call attention, and consider changing export routes and traders. .

  In view of such circumstances, the present invention solves the above-described problems of the prior art, absorbs the impact by the shock absorber to prevent damage to the protector, and further detects, for example, that the impact has been applied from the outside of the cardboard box. An object of the present invention is to provide a roll product protector that can detect the time when an impact is applied.

The present invention was made to achieve the above object, and claim 1 of the present invention is a protector for roll products having a side plate portion and a support shaft protruding from the center portion of the side plate portion.
The roll product protector is characterized in that a buffer portion for absorbing an impact is provided on the outer periphery of the side plate portion.

  Claim 2 of the present invention is characterized in that the buffer portion is extended on the outer periphery of the side plate portion, the strength of the buffer portion is smaller than the strength of the side plate portion, and the shock is absorbed when the buffer portion breaks. The protector for roll products according to claim 1.

  According to a third aspect of the present invention, the buffer portion includes a frame body provided outside the outer peripheral rib of the side plate portion, and a connection portion that connects the outer peripheral rib and the frame body. The protector for roll products described is included.

  According to a fourth aspect of the present invention, there is provided the protector for a roll product according to the third aspect, wherein the connection part is formed thin in whole or in part.

  According to a fifth aspect of the present invention, there is provided the roll product protector according to the third aspect, wherein the connecting portion is obliquely provided.

  According to a sixth aspect of the present invention, the protector for roll products according to the first aspect is characterized in that the buffer portion is made of an elastic body and is detachably attached to the outer peripheral rib of the side plate portion.

  In the present invention, when handling such as dropping, throwing, etc. is bad, the shock absorber is provided on the side plate portion of the protector for roll products which is most easily affected by the impact from the outside, so the shock is absorbed by this side plate portion. Damage to the protector is prevented. As a result, the roll plate is damaged near the boundary between the side plate portion and the support shaft, or the end portion of the side plate portion is damaged, and the width of the roll product comes into contact with or collides with the inner surface of the packing band or cardboard box. Trouble that product is damaged or gets dirty is prevented.

Also, the buffer part is extended on the outer periphery of the side plate part, the strength of the buffer part is smaller than the strength of the side plate part, and the shock is absorbed by breaking the buffer part, thereby preventing damage to the protector. Is done. In addition, when the protector is molded with a mold, the buffer portion can be integrally molded, which is convenient.
Specifically, the buffer portion is formed by a frame body provided on the outer side of the outer peripheral rib of the side plate portion, and a connection portion that connects the outer peripheral rib and the frame body, or the connection portion is entirely or partially. It can be formed suitably by forming it thinly or by providing a connecting portion obliquely.

  In addition, when the buffer portion is formed of an elastic body, it is easy and convenient to form the buffer portion by post-processing and to be detachably attached to the outer peripheral rib of the side plate portion. It is also easy to attach to existing protectors.

  Further, it is convenient to provide an impact display means for indicating that the buffer portion has received an impact. If such an impact display means is a liquid colorant enclosed in a container that is torn by impact, the liquid colorant that is torn and encapsulated when subjected to an impact oozes out of the cardboard box, for example, Without opening the box, it is possible to easily recognize that an impact has been received from the outside of the cardboard box.

  Furthermore, by incorporating a watch that stops due to an impact, it is possible to know the time when the impact was received from the time when the watch stopped. If the watch also displays the date, the date and time of the impact are specified, so it is important to identify the transportation process during which the impact was received. You can track and identify what you received. As a result, it is possible to give attention to the merchant, possibly change the merchant, and change the transportation route.

  The roll product protector 1 according to the present invention is, for example, as shown in FIGS. 1 and 2, in the roll product protector 1 having a side plate portion 2 and a support shaft 3 protruding from the center portion of the side plate portion 2. A buffer portion 4 for absorbing an impact is provided on the outer periphery of the side plate portion 2.

The side plate portion 2 in the present invention is substantially the same as the side plate portion 2 used in the conventional protector for the purpose of protecting the end face of the roll product R and preventing the roll product R from slipping out into a bamboo shoot shape. In general, in order to reduce the weight and increase the strength, a rib 2b appropriately provided on the outer surface side of the thin plate that contacts the end surface of the roll product R is used. The thin plate portion may be provided with a through hole 2d for the purpose of decorating the protector or for the purpose of reducing the weight, if necessary.
Further, the support shaft 3 in the present invention is inserted into the hollow hole of the core material R1 in a conventional protector, and is supported in a suspended manner so that the width surface of the roll product R does not contact the packing band 6 or the inner surface of the cardboard. It is substantially the same as the support shaft 3 used for the purpose. Usually cylindrical.

The present invention is characterized in that a buffer portion 4 for absorbing an impact is provided on the outer periphery of the side plate portion 2. The structure of the buffer portion 4 is not particularly limited as long as the impact applied to the protector 1 can be mitigated, but in this example, as shown in FIG. 1, the frame body 4 a is provided outside the outer peripheral rib 2 a of the side plate portion 2, The frame 4a and the outer peripheral rib 2a are connected by the connecting portion 4b, and when the impact is applied, the connecting portion 4b is broken to absorb the impact.
When the frame body 4a is provided so as to surround the entire outer periphery of the side plate portion 2 as in the case of the protector of this example, the packing band 6 is attached to the frame body so that the packing band 6 does not loosen even if the buffer portion 4 is broken. It is preferable that a part of the outer peripheral rib 2a of the side plate portion 2 inside 4a is a band groove 2c.

  When the buffer part 4 composed of the frame body 4a and the connection part 4b is provided outside the outer peripheral rib 2a of the side plate part 2, the frame body 4a can be provided so as to surround the entire outer periphery as shown in FIGS. As shown in FIGS. 3 and 4, a part where the frame body 4 a is not provided is provided on a part of the outer periphery of the side plate part 2, and a part of the outer peripheral rib 2 a of the side plate part 2 is fastened with the packing band 6. The band groove 2c may be used. In this case, since the band groove 2c is opened, the tightening work by the packing band is easy.

  As described above, the connection portion 4b needs to have a low strength so that when the protector 1 is subjected to an impact, it is destroyed before the protector 1 is damaged. The method of reducing the strength of the connecting portion 4b is not particularly limited, but the entire connecting portion 4b is made thin, or a part of the connecting portion is cut as shown in FIGS. The method of forming thinly is mentioned. How much strength is reduced is appropriately determined in consideration of the weight of the roll product, the type of resin as the material, and the like.

As another method for reducing the strength of the connecting portion 4b, as shown in FIG. 5, the connecting portion 4b is provided obliquely between the outer peripheral rib 2a of the side plate portion 2 and the frame 4a. A method is mentioned.
As described above, the protector in which the buffer portion 4 is integrally provided on the outer peripheral rib 2a of the side plate portion 2 has an advantage that it can be molded at once with a mold using resin. Of course, if necessary, the frame and the connecting part can be separately formed and attached to the outer peripheral rib of the side plate part of the protector using an appropriate attachment. In this case, the buffer part 4 is unnecessary. Can be removed or applied to existing protectors.

The roll product protector 1 in which the buffer portion 4 is formed on the outer peripheral rib 2a of the side plate portion 2 has been described above. For example, as shown in FIGS. 6 and 7, the outer rib 2a of the side plate portion 2 has an elastic body. The buffer part 4 which consists of can also be attached.
As such an elastic body, one that absorbs impact by elastic deformation is used, and examples thereof include rubber, elastomer, foamed resin such as polyethylene foam, polyurethane foam, and the like. The buffer portion made of an elastic body can be detachably attached to the outer peripheral rib 2 a of the side plate portion 2. It can also be easily attached to existing protectors. The degree of impact absorption of the elastic body is appropriately determined in consideration of the weight of the roll product, the type of elastic body, and the like.
A method for attaching the buffer portion 4 made of an elastic body to the outer peripheral rib 2a of the side plate portion 2 is not particularly limited. However, if the elasticity of the elastic body is used, it can be attached without using a fixture. For example, in FIGS. 6 and 7, a groove having an L-shaped cross section is formed inside the buffer portion 4 formed in a donut shape, and the outer peripheral rib 2 a of the side plate portion 2 is fitted into the groove, thereby 4 is attached to the side plate part 2. As shown in FIGS. 6 and 7, when the buffer portion 4 is provided on the entire periphery of the side plate portion 2, a packing band may be hung on the buffer portion 4, and the through hole 2 d near the outer periphery of the side plate portion 2. Can also be used as the band groove 2c. If the former buffer part 4 is hung and tightened, there is an advantage that the band is less likely to loosen due to the intervention of the buffer part.
Also in this case, as shown in FIG. 8, it is not necessary to attach the buffer portion 4 to the entire outer periphery of the side plate portion 2, and the buffer portion 4 is not provided in a part of the outer periphery, and a part of the outer peripheral rib 2a is formed in the band groove 2c. Can be used as

  The protector for roll products of this invention can know that the impact was added to the protector by providing an impact display means further. As such an impact display means, for example, those that can be seen from the outside without opening a cardboard box are preferable. For example, liquid colorant enclosed in a container that is broken by impact, specifically, a plastic or film bag And ink enclosed in a container. By providing such an impact display means, when an impact is applied, the buffer part is destroyed or elastically deformed (compressed), and at the same time, the container is destroyed and the ink oozes out to the outside of the cardboard box. The cardboard box can be easily seen from the outside without opening the cardboard box, and it is possible to check whether the roll product is damaged or to give attention to the trader.

  The protector for roll products of this invention can also be equipped with the timepiece which stops further by an impact. Such a watch is preferably one that also displays the date. By providing a watch in this way, it is possible to track and identify in which country, in which region, and under which merchant the shock was received, from the date and time when it stopped due to the impact, so it is improved for the merchant. , In some cases, changing the trader, changing the transportation route, etc.

FIG. 9 and FIG. 10 show an example in which a liquid colorant enclosed in a container that is easily broken by impact is used as the impact display means 5. Specifically, red ink sealed in a thin plastic sheet container 5a is used as the impact display means 5, and the shock absorber 4 of the protector 1 shown in FIGS. 3 and 4, that is, the outer peripheral rib 2a and the frame 4a. The impact display means 5 is provided between them.
According to such a protector 1, when a strong impact is applied, the thinned portion 4 c of the buffer portion 4 is broken, so that the buffer portion 4 is destroyed and the impact is alleviated. 5a is crushed. As a result, the enclosed red ink 5b leaks and oozes out of the cardboard box (not shown) containing the roll product R, so that it can be easily recognized that a strong impact has been applied to the protector 1. .

In the examples shown in FIGS. 9 and 10, in consideration of the fact that a strong impact is often generated by dropping a cardboard box in which the roll product R is stored, an impact display is provided only on the lower side of the buffer portion 4. Although the means 5 is provided, the impact display means 5 may be provided on two or more sides, preferably on four sides. In this case, not only is it possible to cope with a cause other than dropping, for example, when a cardboard box is thrown or thrown, or it falls and rolls over, etc., but it is once dropped and one of the impact display means 5 is destroyed. Even in this case, it is possible to detect the impact again by changing the posture of the cardboard box so that the other surface becomes the lower surface.
In addition, although the buffer part 4 should just be provided in at least 1 of the side-plate part 2 of the protector 1, Preferably it is provided in 2 sides or more, More preferably, it is provided in 4 sides for the reason mentioned above.

FIG. 11 shows an example in which a timepiece 5 c that stops due to an impact is used as the impact display means 5. In this case, a timepiece 5c is provided between the buffer portion 4 of the protector 1 shown in FIG. 5, that is, between the outer peripheral rib 2a and the frame 4a.
According to such a protector 1, when a strong impact is applied, the connection portion 4 b of the buffer portion 4 is broken, so that the buffer portion 4 is destroyed and the impact is alleviated. At that time, the watch 5 c is crushed. Stop at the time of impact. It is possible to follow up the transportation process and traders that have received an impact from the time of the stop.

  FIGS. 12 and 13 show an example in which the impact display means 5 is provided on the protector 1 using an elastic body provided on the outer periphery of the side plate portion 2 as the buffer portion 4. In this example, a cavity is provided in a part of the buffer portion 4 of the protector 1 shown in FIG. 8, and an impact display means 5 in which a colorant 5b is sealed in a container 5a is embedded. According to such a protector 1, when a strong impact is applied, the buffer portion 4 is elastically deformed (compressed), the container 5a of the impact display means 5 is crushed, and the red ink 5b leaks out, thereby protecting the protector. The effect of visually recognizing that a strong impact has been applied to 1 is the same as in the case of FIGS.

  FIG. 14 shows the protector 1 provided with both the ink 5 (5b) and the clock 5 (5c) enclosed in the container. In this case, when the impact is applied, it is visually recognized that the ink has spilled out of the cardboard box, so it is visually recognized that the impact was applied depending on the stop time of the clock. It is possible to follow up more accurately.

As shown in FIG. 15, the protector 1 according to the present invention sandwiches both end surfaces of the roll product R between the side plate portions of the pair of protectors 1 as in the case of the conventional protector P, and the support shaft 3 is a hollow hole in the core material. The roll product R is supported in a suspended shape by inserting it into the strap, and if necessary, the packing band 6 is hung in a cross shape on the outside of the both side plates 2 and tightened as a whole, and if necessary, it is wrapped with a shrink film. Further, it is housed in a cardboard box (not shown) or the like for transportation and storage.
When a strong impact is applied to the protector 1, as shown in FIG. 16, the shock absorber 4 is destroyed (if the shock absorber is made of an elastic body, the shock absorber is elastically contracted), so that the shock is absorbed. Since the protector 1 is not damaged, the state in which the roll product R is supported in a suspended shape is maintained, and troubles in which the end surface and the peripheral surface of the roll product R are damaged or dirty are prevented.

As described above, the protector for roll products of the present invention is provided with a buffer part on the outer periphery of the side plate part, so that even if a strong impact is applied during transportation or handling, the protector is prevented from being damaged. In addition, since the roll product is maintained in the original suspended state, the trouble that the end surface and the width surface are damaged or dirty is prevented.
In addition, by providing impact indication means, it is possible to easily check at which stage in the transportation process, where the contractor was handling the roll product during the handling, etc. Can be changed, and can help prevent recurrence. Therefore, the protector for roll products of the present invention is extremely useful as a protector for roll products for long-distance transportation, particularly through many transportation means.
