Description

【0001】
[発明の属する技術分野]
本発明は、物流保管時における物品の保護緩衝に用いられる、螺線形緩衝材の製造方法に関するものである。
【0002】
[従来の技術]
従来の緩衝材としては、合成樹脂を材料とし、特定形状に金型により成形された、例えば発泡スチロールのものや、バラ状の発泡スチロールに代表される合成樹脂バラ状緩衝材、澱粉等を材料とする生分解性の緩衝材、木毛等が、又長尺物の保護緩衝材としてトムソン型によりプレス加工した発泡ポリエチレン等による受け台が知られている。
また、シート状の緩衝材としては、合成樹脂を材料として押し出し法やインフレーション法による発泡シートやロッド(丸棒)状緩衝材等が知られている(例えば、特公昭42−004512、特公平9−24974、特公平10−316785公報参照)。
【0003】
[発明が解決しようとする課題]
従来の緩衝材のうち、合成樹脂を材料とする、例えば発泡スチロール成形品は高価な金型を必要とし、しかも特定形状に成形される専用の緩衝材であるため、他に転用できない。また、トムソン型によりプレス加工される、発泡ポリエチレン等による受台も同様である。
更に、発泡スチロールに代表される合成樹脂発泡体によるバラ状緩衝材は、その使用時、被包装物と外装ケースの間への詰め込み作業で折れたり割れたりすることがままあり、澱粉等による生分解性緩衝材は、割れやすく、また湿気を吸収して柔らかくなり、重量物の緩衝材としては適しないし、木毛は生木を材料とするため森林破壊の一因とされ、そして、合成樹脂による発泡シートやロッド状緩衝材は大掛かりな製造設備を必要とする等、それぞれの問題点を有している。
【0004】
本発明は、特定形状の物品だけでなく汎用性があり、軽量又は重量物に拘わらず使用できる筒状、シート状、バラ状等の緩衝材と、その製造方法を提供することを目的としている。

上記により得られた材料を、筒状となる押しバネ状の螺旋形に成形することで空洞を有し、互いが絡み合い、材料の柔軟性と相俟ってより多くの緩衝空間を得て、物流時における衝撃を吸収するものとした。
【0008】

【0009】
紙類等熱融着性のない材料にあっては、接着剤等で上記同様に接着し、筒状となる押しバネ状の螺旋形とした。
【0010】
又、例えば紙類等吸水性のある素材による縒り紐又は縄等の材料にあっては、予め含水させた縒り紐又は縄等を、1本又は複数本の巻きつけシャフトに順次巻きつけながら、熱風等を吐出し乾燥させることにより成形し、融着又は接着しない筒状となる押しバネ状の螺旋形とした。
【0011】
上記のように、任意な太さとした縒り紐又は縄等を材料として得られた筒状となる押しバネ状の螺旋形緩衝材を、必要十分な寸法にカットしてバラ状緩衝材とした。(例えば、横断寸法が約20x20x40mm大のものが望ましい寸法である。)

[Technical field to which the invention belongs]
The present invention relates to a method for manufacturing a spiral cushioning material used for buffering articles during distribution storage.
[0002]
[Conventional technology]
As a conventional cushioning material, a synthetic resin is used as a material, and a specific shape molded by a mold, for example, a foamed polystyrene foam or a synthetic resin rose foamed buffer represented by a rose foamed polystyrene, a starch or the like is used as a material. A pedestal made of a biodegradable cushioning material, wood wool or the like, and a foamed polyethylene or the like pressed by a Thomson mold as a protective cushioning material for a long object is known.
As the sheet-like cushioning material, a foamed sheet or a rod (round bar) -like cushioning material made of a synthetic resin by an extrusion method or an inflation method is known (for example, Japanese Patent Publication No. 42-004512, Japanese Patent Publication No. -24974, Japanese Patent Publication No. 10-316785).
[0003]
[Problems to be solved by the invention]
Among the conventional cushioning materials, a molded article made of a synthetic resin, for example, a styrofoam molded product requires an expensive mold and is a dedicated cushioning material molded into a specific shape, so that it cannot be used for other purposes. The same applies to a pedestal made of foamed polyethylene or the like, which is pressed by a Thomson mold.
Furthermore, a loose cushioning material made of synthetic resin foam represented by Styrofoam may be broken or broken during the packing operation between the packaged object and the outer case during use, and may be biodegraded by starch or the like. The buffer material is fragile, absorbs moisture and softens, is not suitable as a cushioning material for heavy objects, and wood wool is made of raw wood, which contributes to deforestation. Foam sheets and rod-shaped cushioning materials have their respective problems, such as requiring large-scale manufacturing equipment.
[0004]
An object of the present invention is to provide not only articles having a specific shape but also versatility, and a cushioning material having a tubular shape, a sheet shape, a loose shape, and the like that can be used regardless of a light weight or a heavy object, and a method for manufacturing the same. .

[Means for solving the problem]
In order to achieve the above object, the cushioning material of the present invention is a paper or a wet or dry nonwoven fabric containing heat-fusible polyethylene or polypropylene, various films and cloths, and other materials of any thickness. A material such as a string or a rope was used, and the shape of the cushioning material to be obtained was a helical shape of a tubular compression spring.
[0006]
When the above material is used as a material such as a twisted string or a rope, by adjusting the width, thickness, strength of the twist, a material of any thickness having a softness and hardness effective as a cushioning material And
[0007]
The material obtained as described above has a cavity by being formed into a tubular, push-spring-like spiral shape, and is entangled with each other to obtain more buffer space in combination with the flexibility of the material. Shock during distribution was absorbed.
[0008]
In order to form and hold a tubular spring-shaped spiral, a spiral wound sequentially around one or a plurality of winding shafts is used for a heat-fusible material. Or, between ropes, etc., by a heating device such as a hot plate heated to the fusion temperature, mutually fused or irregularly fused, or intermittently fused, to form a tubular spring-shaped Spiral.
[0009]
Materials such as paper that do not have heat-fusing properties are bonded in the same manner as described above with an adhesive or the like, and are formed into a cylindrical shape of a pressing spring.
[0010]
In addition, for example, in the case of a material such as a twisted string or a rope made of a water-absorbing material such as paper, while winding a previously impregnated twisted string or a rope around one or more winding shafts sequentially, It was formed by discharging hot air or the like and drying to form a cylindrical shape that does not fuse or adhere to each other.
[0011]
As described above, the tubular spring-shaped helical cushioning material obtained by using a twisted string or a rope having an arbitrary thickness as a material was cut into necessary and sufficient dimensions to obtain a rose-shaped cushioning material. (For example, a size having a transverse dimension of about 20 × 20 × 40 mm is a desirable dimension.)
[0012]
A sheet-like cushioning material is formed by forming a helical tubular shape of a pressing spring that becomes a tubular shape by heating and fusing or adhesive bonding of adjacent strands and other materials. It was.

A cushioning material made into a sheet. 筒状となる押しバネ状螺線形を成形、保持するにあたり、例えば熱融着性のある素材を、任意な太さの材料とした縒り紐(11)は、モーターなどの駆動装置(4)の回転を直接に、又は伝導ベルト(9)等を介して、1本又は複数本の巻きつけシャフト(2)と、回転する送りローラー(3)との間にあって順次巻きつけ送り出され、ヒーター板等の加熱装置(5)で加熱される事により、隣り合う螺旋紐が互いに規則的に融着された螺線形(1)、あるいは不規則的に(1−イ)、また間欠に(1−ハ)融着された筒状となる押しバネ状の螺線形、又隣り合う縒り紐を互いに融着することのない筒状となる押しバネ状の螺線形(1−ヘ)を成形、保持し、コンベア等の搬送装置(6)を経て、カッター(7)等により任意な長さに裁断された、筒状となる押しバネ状の螺旋形状を特徴とする緩衝材の製造方法。In forming and holding the push-spring spiral formed into a cylindrical shape, for example, a twisted string (11) made of a material having an arbitrary thickness using a heat-fusible material is used for a driving device (4) such as a motor. Directly or via a conductive belt (9) or the like, one or a plurality of winding shafts (2) and a rotating feed roller (3) are sequentially wound and sent out, and heated plates and the like. Is heated by the heating device (5), the adjacent spiral cords are regularly fused to each other in a spiral (1) or irregularly (1-a), and intermittently (1-a). Forming and holding a pressed spring-shaped spiral formed into a fused tubular shape, and a tubular pressed spring-shaped spiral (1-f) that does not fuse adjacent stranded cords to each other; After passing through a conveyor (6) such as a conveyor, it is cut to an arbitrary length by a cutter (7) or the like. And method for producing a cushioning material, wherein the press spring-like spiral shape having a cylindrical shape. 吸水性のある素材を、任意な太さの材料とした縒り紐などを筒状の押しバネ状の螺旋形に成形する場合も、請求項5と同様に、予め含水させた縒り紐などの材料を、1本又は複数本の巻きつけシャフトに巻きつけ、または巻きつけながら、加熱乾燥等することにより成形し、隣り合う縒り紐などは互いに接着することのない筒状の押しバネ状の螺旋形を成形、保持し送り出し、カッター等により任意な長さに裁断された、押しバネ状の螺旋形状を特徴とする緩衝材(1−ヘ)の製造方法。Also in the case where a twisted cord or the like made of a material having an arbitrary thickness from a water-absorbing material is formed into a cylindrical shape of a pressing spring, a material such as a previously impregnated twisted cord or the like is used. Is wound around one or more winding shafts, or is formed by heating and drying while being wound, and the adjacent twisted cords and the like are formed in a tubular push-spring helical shape that does not adhere to each other. A method for manufacturing a cushioning material (1-f) characterized by a helical shape in the shape of a push spring, which is formed, held, fed out, and cut into an arbitrary length by a cutter or the like.
