Description

この発明は、食品搬送ライン、物流搬送ラインなどに使用される軽量搬送ベルトを所定の進路を走行させるためのガイド部材に関する。   The present invention relates to a guide member for causing a lightweight conveyance belt used in a food conveyance line, a distribution conveyance line, and the like to travel on a predetermined route.

本発明に係る軽量搬送ベルトは、図２（ａ）に側面図を示し、図２（ｂ）に図２（ａ）のＡ−Ａ断面図を示すように、ガイドプーリ４，４’に懸回され、ベルト本体３の内周面にガイド部材２を接着しており、図２（ｂ）に断面図を示すように、ガイドプーリ４、４’にはガイド溝８が設けられ、ガイド部材２は、このガイド溝８に嵌合してガイドプーリ４、４’上での走行位置を制御して軽量搬送ベルト１の蛇行を防止する。ベルト本体３は通常、芯体帆布にカバー材としてポリウレタンや軟質ポリ塩化ビニールなど常温で弾性体である熱可塑性合成樹脂を積層している。ガイド部材２は通常、前記カバー材に類似する材料を押出機により断面形状台形である紐状体に押出成形されている。   The light weight transport belt according to the present invention is shown in FIG. 2 (a) as a side view and as shown in FIG. 2 (b) as a cross-sectional view along AA in FIG. 2 (a). The guide member 2 is bonded to the inner peripheral surface of the belt main body 3, and the guide pulleys 4 and 4 'are provided with guide grooves 8 as shown in the sectional view of FIG. 2 is fitted in the guide groove 8 to control the traveling position on the guide pulleys 4 and 4 ′ to prevent meandering of the lightweight conveyance belt 1. The belt body 3 is usually formed by laminating a thermoplastic synthetic resin, which is an elastic body at normal temperature, such as polyurethane or soft polyvinyl chloride, as a cover material on a core canvas. The guide member 2 is usually formed by extrusion of a material similar to the cover material into a string-like body having a trapezoidal cross section by an extruder.

従来のガイド部材２’は図３（ａ）に断面を示すように、断面台形の底面１１’が平面であって、上側部には長さ方向に連続する上側溝９を設けている。上側溝９は、ガイドプーリ４、４’のガイド溝による圧縮疲労を軽減する。   As shown in FIG. 3A, the conventional guide member 2 ′ has a trapezoidal bottom surface 11 ′ having a flat surface, and an upper groove 9 continuous in the length direction is provided on the upper portion. The upper groove 9 reduces the compression fatigue caused by the guide grooves of the guide pulleys 4, 4 '.

このガイド部材２’はベルト本体３に、通常、接着剤により常温接着される。しかし、最近の用途として食品搬送などでは、高温高湿条件（例えば、湿度：９０％、温度：８０℃）で使用されるものがあり、常温接着では使用時に剥離する恐れを生じた。そこで熱硬化性弾性体である接着剤を用いたり（例えば、特許文献１参照）、ガイド部材の貼付面を加熱溶融しながらベルト本体のガイド部材貼付け位置に熱溶着させることが開示されている（例えば、特許文献２参照）。熱硬化性弾性体である接着剤を用いる場合には接着剤のポットライフや価格の点で問題があり、熱接着する場合にはガイド部材２’の底面を溶かして溶着するので貼り付け後のガイド部材２の高さが低くなる問題がある。   This guide member 2 ′ is normally bonded to the belt body 3 with an adhesive at room temperature. However, as a recent application, there is a food transport etc. that is used under high temperature and high humidity conditions (for example, humidity: 90%, temperature: 80 ° C.). Therefore, it is disclosed that an adhesive which is a thermosetting elastic body is used (for example, refer to Patent Document 1), or the adhesive surface of the guide member is heat-welded to the guide member attaching position of the belt body while being heated and melted ( For example, see Patent Document 2). When an adhesive that is a thermosetting elastic body is used, there is a problem in terms of pot life and price of the adhesive. When heat bonding is performed, the bottom surface of the guide member 2 'is melted and welded. There is a problem that the height of the guide member 2 is lowered.

後者の場合、ガイド部材の高さを予め高く設計しても、次の問題が残る。例えば、図３（ｂ）に断面図を示すようにガイド部材２’の底面を加熱し圧着する時、ガイド部材２’の幅方向両端部が先に接着して内部にエアー溜６が残ることがあり、また、図３（ｃ）に示すように、ガイド部材２’の幅方向中央部が先に接着し、または加圧により両端部にバリ７が浮き上がることがある。この状態では、使用中にこれらの部分より剥離を生じ、ベルト蛇行やベルト損傷の原因となり、また、このガイド部材２’などの破損片や、バリの摩耗粉が異物として搬送物に混入する恐れもある。
特開平１１−３５１２２号公報（請求項１） 特開２００２−１６０８１６号公報（請求項３） In the latter case, the following problem remains even if the height of the guide member is designed to be high in advance. For example, as shown in the cross-sectional view of FIG. 3B, when the bottom surface of the guide member 2 ′ is heated and pressure-bonded, both ends in the width direction of the guide member 2 ′ are bonded first, and the air reservoir 6 remains inside. Further, as shown in FIG. 3 (c), the central portion in the width direction of the guide member 2 ′ may be bonded first, or the burr 7 may be lifted at both ends by pressurization. In this state, peeling occurs from these portions during use, causing belt meandering and belt damage, and there is a risk that broken pieces such as this guide member 2 'and burr wear powder may be mixed into the conveyed product as foreign matter. There is also.
JP-A-11-35122 (Claim 1) JP 2002-160816 A (Claim 3)

従来の軽量搬送ベルトのベルト本体へのガイド部材の接着は、常温接着では高温高湿の雰囲気では使用できず、高温高湿の雰囲気中で使用するために熱溶着による場合はエアー溜やバリ発生によりガイド部材の剥離やベルトの蛇行を生じ、ガイド部材の破片や摩耗粉が搬送物に混入するなどの問題があった。本発明は軽量搬送ベルトであって高温高湿の雰囲気中にて使用でき、ベルト蛇行やガイド部材の破片や摩耗粉が発生しない軽量搬送ベルト用のガイド部材を提案することを目的とする。   Adhesion of guide members to the belt body of conventional lightweight conveyor belts cannot be used in high-temperature and high-humidity atmospheres at normal temperature bonding, and air pools and burrs are generated when heat welding is used for use in high-temperature and high-humidity atmospheres. This causes problems such as peeling of the guide member and meandering of the belt, and fragments and wear powder of the guide member are mixed into the conveyed product. An object of the present invention is to propose a guide member for a lightweight transport belt that is a lightweight transport belt and can be used in a high-temperature and high-humidity atmosphere and does not generate belt meandering, guide member debris, or abrasion powder.

上記した課題を解決するために請求項１に記載の軽量搬送ベルト用ガイド部材は、常温で弾性体である、ポリウレタン、ポリ塩化ビニールからなる熱可塑性樹脂が断面形状台形の紐状体として押出成形されたもので、帯状のベルト本体の内周面に溶着される、軽量搬送ベルト用ガイド部材であって、底面部に長さ方向に連続する複数本の下側溝が間隔をおいて形成され、前記下側溝の深さが０．５〜０．７ｍｍであることを特徴とする。 In order to solve the above-described problems, the lightweight conveying belt guide member according to claim 1 is formed by extrusion of a thermoplastic resin made of polyurethane or polyvinyl chloride, which is an elastic body at room temperature, as a string-like body having a trapezoidal cross section. It is a lightweight conveyance belt guide member that is welded to the inner peripheral surface of the belt-shaped belt body, and a plurality of lower grooves continuous in the length direction are formed at intervals on the bottom surface portion, The depth of the lower groove is 0.5 to 0.7 mm.

ガイド部材として用いられる熱可塑性弾性体は、ポリウレタン、軟質塩化ビニール、ポリエステルなどであって１００℃近い水蒸気に曝されてもガイド部材として必要な剛性を有し、常温でガイドプーリに馴染むことができ、また、高周波ウェルダーやホットエアジェット等により溶融できるものが選択される。なおこの弾性体は、通常ベルト本体のカバー材との接着を容易とするためにこれと同材質のものが使用されことが多い。   The thermoplastic elastic body used as a guide member is polyurethane, soft vinyl chloride, polyester, etc., and has the necessary rigidity as a guide member even when exposed to water vapor near 100 ° C., and can adapt to the guide pulley at room temperature. In addition, a material that can be melted by a high-frequency welder or a hot air jet is selected. The elastic body is usually made of the same material as the belt body in order to facilitate adhesion with the cover material of the belt body.

ガイド部材の断面形状は台形であって、帯状のベルト本体に溶着する部分である底面部に長さ方向に連続する複数本の下側溝を間隔をおいて形成することにより、この底面部を加熱溶融するための加熱エアーを流れやすくし、また、ガイド部材の底面部とベルト本体との間のエアーは、長さ方向に連続する複数本の下側溝を通って逃げ出し易く、滞留することがない。さらに、この複数本の下側溝により接着面を均一に早く加熱することができるので、ガイド部材全体の歪みがなくバリの発生もなくすることができる。
前記下側溝の深さは、０．５ｍｍ未満では、熱風で簡単に溶融できる量（溶着代）が少なすぎて接着不良となり、０．７ｍｍを超えるとエアー溜まりにより接着力が不足する。
The cross-sectional shape of the guide member is trapezoidal, and a plurality of lower grooves continuous in the length direction are formed at intervals on the bottom surface portion that is a portion welded to the belt-shaped belt body, thereby heating the bottom surface portion . Heating air for melting easily flows, and air between the bottom surface of the guide member and the belt body easily escapes through a plurality of lower grooves continuous in the length direction and does not stay. . Further, since the adhesive surface can be uniformly and quickly heated by the plurality of lower grooves , the entire guide member is not distorted and burrs are not generated.
If the depth of the lower groove is less than 0.5 mm, the amount that can be easily melted with hot air (welding allowance) is too small, resulting in poor adhesion, and if it exceeds 0.7 mm, the adhesive strength is insufficient due to air accumulation.

なお、ガイド部材の高さは、複数本の下側溝が間隔をおいて形成されている底面部が、溶着時に溶融され潰されることを前提に設計することができ、溶着することによりガイド部材の高さが不安定になることがない。また、上側面にはガイド部材の長さ方向に連続する溝部を形成し、ガイドプーリのガイド溝での圧縮による破壊を減少させることができる。
The height of the guide member can be designed on the assumption that the bottom surface portion where the plurality of lower grooves are formed at intervals is melted and crushed at the time of welding. The height does not become unstable. Moreover, the groove part which continues in the length direction of a guide member can be formed in an upper surface, and the destruction by the compression in the guide groove of a guide pulley can be reduced.

底面部に長さ方向に連続する複数本の下側溝が間隔をおいて形成されているので、下側溝のエアーは、貼付け作業の進捗に従って順次を容易に押し出され、かつ、ホットエアーが通りやすく加熱が均一で容易になる。また、ガイド部材の長さ方向に連続する複数本の下側溝はダイ形状を工夫することにより押出機により容易に成形できる。
Since a plurality of lower grooves that are continuous in the length direction are formed at intervals on the bottom surface, the air in the lower grooves is easily pushed out sequentially in accordance with the progress of the pasting operation, and hot air can easily pass therethrough. Heating is uniform and easy. Further, a plurality of lower grooves continuous in the length direction of the guide member can be easily formed by an extruder by devising a die shape .

請求項２に記載のガイド部材は、前記複数本の下側溝の合計幅は、前記底面部の幅の１／３〜１／２であることを特徴とする。下側溝の断面形状としては四角形、三角形、半円形など特定するものではない。下側溝の合計幅（複数本の下側溝の幅の合計をいう）が底面の幅の１／３未満であればエアーが十分に抜けきらないことがあり、１／２を超えると下側溝の一部にエアー溜まりを生じ接着力が不足する問題がある 。
The guide member according to claim 2 is characterized in that a total width of the plurality of lower grooves is 1/3 to 1/2 of a width of the bottom surface portion . The cross-sectional shape of the lower groove is not specified as a quadrangle, a triangle, or a semicircle. If the total width of the lower groove (referred to as the sum of the widths of the plurality of lower grooves ) is less than 1/3 of the width of the bottom surface, air may not be sufficiently removed. There is a problem in that some of the air is trapped and the adhesive strength is insufficient.

以上説明したことから明らかなように、本発明のガイド部材を貼付けた軽量搬送ベルトは、高温高湿雰囲気中で使用できる。即ち、加熱溶融により貼付けられているので高温の水蒸気により加熱される工程においても接着力が低下することなく、かつ、ガイド部材の貼付け面全体がベルト本体に均一に貼付けられているので剥離したり摩耗することがなく、ベルト蛇行や搬送物に異物が混入することもない。特に、長さ方向に連続する複数本の下側溝により溶着時に底面部のエアーは一層抜けやすく、接着力は安定する。 As is clear from the above description, the lightweight conveyor belt to which the guide member of the present invention is attached can be used in a high temperature and high humidity atmosphere. That is, since it is affixed by heating and melting, the adhesive force does not decrease even in the process of being heated by high-temperature steam, and the entire affixing surface of the guide member is evenly affixed to the belt body, so that it can be peeled off. There is no wear, and no foreign matter is mixed into the belt meandering or transported object. In particular, the plurality of lower grooves continuous in the length direction make it easier for air at the bottom surface to escape during welding , and the adhesive force is stabilized.

本発明のガイド部材の最良の形態は、常温で弾性体であるポリウレタンを断面形状が台形である紐状体に押出成形したものであって、前記紐状体の底面部にガイド部材の長さ方向に連続する下側溝を形成して溶着代とする。なお、この下側溝は３本としてこの下側溝の合計幅は底面部全幅の約３／７とし、下側溝の深さは約０．６ｍｍとした。   The best mode of the guide member according to the present invention is an extrusion molding of polyurethane, which is an elastic body at room temperature, into a string-like body having a trapezoidal cross section, and the length of the guide member is formed on the bottom surface of the string-like body. A lower groove continuous in the direction is formed to provide a welding allowance. The number of the lower grooves is three, the total width of the lower grooves is about 3/7 of the entire width of the bottom surface, and the depth of the lower grooves is about 0.6 mm.

（実施例）
以下、本発明に係る軽量搬送ベルト用ガイド部材を図１を参照しながら実施例を説明する。図１（ａ）はガイド部材２の断面図を示しほぼ台形である。なお、詳しくは、底面部１１には３本の下側溝５が等間隔に形成され、上面部１０には２本の上側溝９が形成されている。底面部１１の下側溝５は、ガイド部材２の長さ方向に連続した形状であり、一本の下側溝５は幅がｗであり、深さはｄである。この下側溝５の幅ｗに溝の本数を乗じた値（３ｗ）は、底面部１１の全幅Ｗの約３／７である。 (Example)
Hereinafter, an embodiment of the guide member for a lightweight conveyance belt according to the present invention will be described with reference to FIG. FIG. 1A shows a sectional view of the guide member 2 and is substantially trapezoidal. Specifically, three lower grooves 5 are formed at equal intervals on the bottom surface portion 11, and two upper grooves 9 are formed on the upper surface portion 10. The lower groove 5 of the bottom surface portion 11 has a shape that is continuous in the length direction of the guide member 2, and one lower groove 5 has a width w and a depth d. A value (3w) obtained by multiplying the width w of the lower groove 5 by the number of grooves is about 3/7 of the total width W of the bottom surface portion 11.

このガイド部材２は、常温で弾性体であるポリウレタン（日本ポリウレタン工業株式会社製、商品名Ｅ−９８０ＰＴＥＣ）を用いて図示しない押出機により断面台形（高さ＝５．５ｍｍ、底面部幅＝１０．０ｍｍ、上面部幅＝６．０ｍｍ）に押し出し、底面部には幅ｗ＝１．０ｍｍ、深さ＝０．３ｍｍである断面四角形である下側溝５を３本を等間隔に形成し、上側部には上側溝９を２本形成している。なお、下側溝５の寸法（幅ｗ、深さｄ）は、ベルト本体３に溶着した後（図１（ｂ）参照）に、ガイド部材２の高さが軽量搬送ベルトの用途により設計される高さｈとなるよう設計される（溶融により下側溝に凸部が流れ込み、下側溝５の深さｄの約１／２〜１／３ガイド部材の高さが低くなる）。   This guide member 2 has a trapezoidal cross section (height = 5.5 mm, bottom surface width = 10) using an unillustrated extruder using polyurethane (Nippon Polyurethane Industry Co., Ltd., trade name E-980PTEC) which is an elastic body at room temperature. The bottom groove 5 is formed in a square shape with a width w = 1.0 mm and a depth = 0.3 mm, and three lower grooves 5 are formed at regular intervals. Two upper grooves 9 are formed in the upper part. In addition, the dimension (width w, depth d) of the lower groove 5 is designed so that the height of the guide member 2 depends on the use of the lightweight conveyance belt after being welded to the belt body 3 (see FIG. 1B). The height is designed to be h (the protrusion flows into the lower groove due to melting, and the height of the guide member about 1/2 to 1/3 of the depth d of the lower groove 5 is reduced).

溶着手順は、先ずベルト本体３をその側辺部１５を案内定規２４に沿わせて作業台１２の上に載置する。ガイド部材２をガイド部材貼付け冶具５０の操作ハンドル２８の中空部（図示せず）を通して加圧ローラ２５の下部に案内して貼付位置２３に当接する。このガイド部材２の底面部１１（図１（ａ）参照）を、加熱手段２６より吹き出す熱風により溶融しながらガイド部材貼付け冶具５０を矢印ｘの方向に移動させてベルト本体３の上面に溶着する。なお、ベルト本体３の上面はガイド部材２と接着しやすい材料であるポリウレタンを用いている。   In the welding procedure, the belt main body 3 is first placed on the work table 12 with the side 15 thereof along the guide ruler 24. The guide member 2 is guided to the lower portion of the pressure roller 25 through the hollow portion (not shown) of the operation handle 28 of the guide member attaching jig 50 and is brought into contact with the attaching position 23. While the bottom surface portion 11 (see FIG. 1A) of the guide member 2 is melted by the hot air blown from the heating means 26, the guide member attaching jig 50 is moved in the direction of the arrow x to be welded to the upper surface of the belt body 3. . Note that the upper surface of the belt body 3 is made of polyurethane, which is a material that easily adheres to the guide member 2.

このガイド部材貼付け冶具５０を案内定規２４に従って矢印ｘの方向に移動させて連続的に溶着した。ガイド部材２をベルト本体３に溶着した軽量搬送ベルトの断面図を図１（ｂ）に示す（図２（ｂ）の円Ｂ部分の拡大図である）。   The guide member attaching jig 50 was moved in the direction of the arrow x according to the guide ruler 24 and continuously welded. FIG. 1B is a cross-sectional view of the lightweight conveyance belt in which the guide member 2 is welded to the belt body 3 (an enlarged view of a circle B portion in FIG. 2B).

このように作成されたガイド部材付き軽量搬送ベルトについて、ベルト本体とガイド部材との接着力、ガイド部材の高さ及び走行テストを行い、結果を表１に示す。なお、接着力測定はＪＩＳ Ｋ−６３２２により測定した。走行テストは、図５に側面図（概要）を示す走行試験機に、試験用エンドレスベルト３０（幅＝１００ｍｍ×長さ＝２８００ｍｍ）を懸回し、矢印ｙの方向に１００ｍ／ｍｉｎの速度で走行させて剥離や傷の有無を確認した。なお、この走行試験機３５のガイドロール３１，３１’の径は１００ｍｍで有り、テンションローラ３２の径は５０ｍｍとした。   With respect to the light-weight transport belt with a guide member created in this way, the adhesive strength between the belt main body and the guide member, the height of the guide member, and a running test were performed, and the results are shown in Table 1. In addition, the adhesive force measurement was measured according to JIS K-6322. In the running test, a test endless belt 30 (width = 100 mm × length = 2800 mm) is suspended from a running test machine whose side view (outline) is shown in FIG. The presence or absence of peeling or scratches was confirmed. The diameter of the guide rolls 31 and 31 'of the running test machine 35 is 100 mm, and the diameter of the tension roller 32 is 50 mm.
