【発明の属する技術分野】
本発明は、野菜、穀物等の食品類の洗浄後の水切り工程や乾燥工程、産業資材部品の乾燥工程等においても幅広く使用される、荷こぼれ防止、傾斜搬送時の滑り止め等の目的で、ベルト表面に桟を接合する桟付き搬送用ベルトに関する。
【０００２】
【従来の技術】
従来より搬送用ベルト表面に、荷こぼれ防止、滑り止め等の目的で、ベルト外周面に金具接合や接着剤接合又は加熱プレス接合等にて桟を取り付けた桟付き搬送ベルトは知られている。例えば、実開昭５８−１０６３１１号公報には、ゴム、樹脂などの弾性体よりなるベルトの表面に、軽量化のため、ウレタンフォーム等の発泡体より成る桟を接着剤にて取り付けたものが開示されており、特開昭６１−１１９５０５号公報には、抗張力維持を目的に、ベルト基布表面及び桟基布表面にポリウレタンやポリ塩化ビニルより成るプラスチックカバーを積層したエンドレスベルト本体及び桟を高周波誘電加熱接合にてプラスチックカバー同士のみを溶融接着したものが開示されている。
【０００３】
【発明が解決しようとする課題】
しかしながら、従来より使用されている桟付きベルトにおいて、桟とベルト基布の接合の点から言えば、例えば桟とベルト本体を金具接合した桟付き搬送ベルトは、金具の脱落や金具の破損、欠け等による搬送物中への異物混入等の問題が有り、特に食品搬送工程には不適とされる場合があった。接着剤接合した桟付き搬送ベルトは、接着強度の点から、桟の剥がれ、脱落等の問題、さらには特に食品、薬剤等の搬送工程には、接着剤の種類によっては不適とされる場合もあった。また加熱プレス接合した桟付き搬送ベルトは、桟やベルト本体の接合部分における樹脂を溶融固化してしまい経時劣化、抗張力保持の点で問題となる場合があった。
【０００４】
次に、桟について言えば、桟がウレタンや塩化ビニル等の樹脂成形一体型のものは成形し易くベルト基布との接合もし易い利点を有するが、例えば、野菜や穀物等の食品の洗浄後の水切り工程に使用される場合においては、桟が通水性を具備しないため、水切り性に劣ると共に、水が桟表面及びベルト表面を横方向に流れてベルトサイドへ流れ落ちる際に、搬送物まで同時に流されてしまうといったサイドリーク（横漏れ）が発生し易いといった欠点があった。また一般的に桟材として汎用されているウレタンフォーム材は、長期間使用時において黄変する傾向があると共に、耐熱温度が常用８０℃以下と低いために、殺菌のための熱水、熱風処理、乾燥処理を行う場合には桟が軟化してしまい不適であった。
【０００５】
前記、実開昭５８−１０６３１１号公報記載及び特開昭６１−１１９５０５号公報記載の桟付き搬送用ベルトにおいても、その構成上、桟及びベルト基布は通水性を具備せず、水切り性やサイドリーク、また上記殺菌処理等衛生面の点から満足できるものではなかった。
【０００６】
本発明はこれらの従来技術に鑑み、桟付き搬送用ベルトにおいて、ベルト基布を劣化させることなく桟とベルト基布を強固に接合し、耐久性に優れ、軽量で、水切り、乾燥工程において好適な桟付き搬送ベルトを提供しようとするものである。特に食品搬送工程において、ベルト構成物からなる異物の混入の恐れのない安全な桟付き搬送用ベルトを提供しようとするものである。
【０００７】
【課題を解決するための手段】
上記課題を解決するため、搬送用ベルト基布の外周面に、搬送物滑止用の複数個の桟を任意間隔をおいて横方向に取り付けた桟付き搬送用ベルトにおいて、ベルト基布及び桟を合成樹脂フィラメントの経糸と緯糸から織成された通気性、通水性を有するメッシュ織物より構成し、桟とベルト基布が接合される部分において、桟を構成する経糸又は緯糸を複数本除去し、除去することにより露出した簾状の経糸又は緯糸の少なくとも一部を、ベルト基布を構成する経糸と緯糸間で形成される目開き部分に挿し込み、挿し込まれた経糸又は緯糸の少なくとも一部をベルト基布のメッシュ組織両側に交互に編み込むことにより、桟とベルト基布が別の接合材を使用せずに強固に接合された通水性を具備した通水性桟付き搬送用ベルトが得られる。本発明による通水性桟付き搬送用ベルトは、桟をベルト基布に取り付け、固定する際に、接着剤や他の接合材を使用せず直接接合するため、ベルト構成物からなる異物混入の恐れがない。また、メッシュ織物は多数の目開き部を有することにより、通気性、通水性を具備し、特に水切り工程に使用される場合、水切り性に優れると同時にサイドリークに優れた桟付き搬送用ベルトとなる。
【０００８】
ベルト基布及び桟は、合成樹脂フィラメントから構成されるのが好ましい。防汚性、剛性等を考慮するとモノフィラメント糸から構成されるのがより好ましい。素材としては、合成樹脂から成るフィラメントであればよく特に限定されないが、耐久性、耐薬品性、耐熱性の点から、ポリエステル（ＰＥＴ）やポリフェニレンスルファイド（ＰＰＳ）が好ましい。殺菌処理、乾燥処理等の高温下にて使用される場合に適用可能となり衛生面でも好ましい。より防汚性を高めるためにはフッ素含有又はフッ素加工されたフィラメントを用いてもよい。
【０００９】
また、搬送用ベルト基布及び桟が経糸と緯糸から織成されたメッシュ織物であることが好ましい。織組織としては、平織り又は綾織りの一重織、又は２／１綾織り等の二重織組織の織物が、通水性、剛性の両特性の点から好ましい。桟本体を構成する経糸又は緯糸の一部をベルト基布に挿込、挿し込んだ糸の一部を利用して、ベルト基布に編み込むことにより、桟とベルト基布が直接接合されるため、桟とベルト基布は同一メッシュ組織のものが好ましい。また、メッシュ織物の目開き部は挿し込む糸の断面積以上が好ましい。編み込む方向は、桟の保持強力を考慮するとベルト基布の経糸方向が好ましく、編み込み本数は、搬送物重量により適宜設定すればよい。編み込み本数が増えるほど桟の保持強力は増加するが編み込む手間も増えるため、桟の必要保持強力に合わせて編み込み本数を設定すればよい。編み込みは桟の片側又は両側いずれでもよいが、桟の固定性を考慮すれば両側編み込みが好ましい。編み込む糸以外は、ベルト基布裏側で切断し、ベルト基布走行の障害とならない程度にカッティングしておくことが好ましい。さらに桟の接合強度が必要な場合には、超音波ウエルダー加工にて補強接合してもよい。経糸、緯糸の線経は０．３〜１．５ｍｍが好ましい。線径が０．３ｍｍ未満では剛性に劣り、１．５ｍｍを超えると製織性が困難になると同時に不経済である。線型は扁平のものを用いてもよい。桟付き搬送ベルトの使用条件により適宜選定すればよい。搬送用ベルト基布及び桟をメッシュ織物より構成することにより、例えば水槽中から搬送物をすくい上げる工程等に使用される場合、水切れがよいと同時に水中での桟付き搬送用ベルトの抵抗が少なくなり、動力負荷が少なく省エネルギー化、搬送スピード向上が可能となる。また、水切り工程後の乾燥工程においても水切り度が高い分、乾燥効率も向上できる。また、桟付き搬送用ベルト自体を軽量化できる。
【００１０】
搬送用ベルト基布が、モノフィラメント糸からなる経糸と緯糸を織成した有端状の基布の両端部に継ぎ手部を設け、該両端部を該継ぎ手部にて連結し無端状としたものが好ましい。継ぎ手の構造としては、有端状のベルト基布の両端部から緯糸を除去して、緯糸を除去することにより露出した簾状の経糸を折り返し、適宜その一部をループ形状とし、経糸の折り返し先端部をベルト基布に織り込み、ベルト基布の両端部に形成された経糸ループ同士を噛み合わせ、噛み合わせて形成される経糸ループ共通孔に接続用芯線を挿通し連結するワープループシーム構造や、前記経糸ループに合成樹脂モノフィラメントからなるスパイラル線条を噛み合わせ、噛み合わせて形成される共通孔にスパイラル線条固定用芯線を挿通し、ベルト基布の両端部に形成されたスパイラル線条同士を噛み合わせ、噛み合わせれ形成されたスパイラル線条共通孔に接続用芯線を挿通し連結するスパイラル構造、又はこれらを組み合わせたものでもよい。このような継ぎ手部を設けることにより、必要に応じ桟付き搬送用ベルトの取り外し、洗浄が可能となり、桟付き搬送用ベルト取り付け機械保全や桟付き搬送用ベルトそのものの保守が簡易化される。

BACKGROUND OF THE INVENTION
The present invention is widely used in the draining process and drying process after washing foods such as vegetables and grains, and the drying process of industrial material parts, etc., for the purpose of preventing spillage, preventing slipping during inclined transportation, etc. The present invention relates to a conveyor belt with a cross that joins a cross to the belt surface.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a conveyance belt with a cross, in which a cross is attached to the outer peripheral surface of the belt by metal fitting bonding, adhesive bonding, or hot press bonding for the purpose of preventing spillage and preventing slipping, is known. For example, Japanese Utility Model Laid-Open No. 58-106311 has a belt surface made of an elastic material such as rubber or resin and a crosspiece made of foamed material such as urethane foam attached to the surface of the belt with an adhesive for weight reduction. Japanese Patent Laid-Open No. 61-119505 discloses an endless belt main body and crosspieces in which a plastic cover made of polyurethane or polyvinyl chloride is laminated on the belt base cloth surface and the crosspiece base cloth surface for the purpose of maintaining tensile strength. A material in which only plastic covers are melt-bonded by high-frequency dielectric heating bonding is disclosed.
[0003]
[Problems to be solved by the invention]
However, in the case of a belt with a crosspiece that has been used conventionally, in terms of the joining of the crosspiece and the belt base fabric, for example, a conveyor belt with a crosspiece that joins the crosspiece and the belt body with a crosspiece will cause the metal fittings to drop off or the metal fittings to be damaged or chipped. There is a problem that foreign matter is mixed into the conveyed product due to the above, and it may be unsuitable for the food conveying process. Adhesive-bonded conveyor belts may not be suitable depending on the type of adhesive in terms of adhesive strength, such as peeling off and falling off of the bars, and especially for transporting foods, drugs, etc. there were. In addition, the conveyance belt with a cross bonded by hot press sometimes melts and solidifies the resin at the bonded portion of the cross and the belt main body, which may cause a problem in terms of deterioration over time and retention of tensile strength.
[0004]
Next, with regard to the crosspiece, the one with a resin-molded integrated type such as urethane or vinyl chloride has the advantage that it is easy to mold and can be easily joined to the belt base fabric. For example, after washing food such as vegetables and grains In the case of being used in the water draining process, since the crosspiece does not have water permeability, the drainage performance is inferior, and when the water flows laterally on the crosspiece surface and the belt surface to the belt side, There is a drawback that side leakage (lateral leakage) is likely to occur. In addition, the urethane foam material that is generally used as a crosspiece tends to turn yellow when used for a long period of time, and since the heat-resistant temperature is as low as 80 ° C. or less, it is treated with hot water and hot air for sterilization. When performing the drying process, the crosspieces softened, which was not suitable.
[0005]
Even in the above-mentioned conveyor belt with a crosspiece described in Japanese Utility Model Publication No. 58-106311 and Japanese Patent Application Laid-Open No. 61-119505, the crosspiece and the belt base fabric do not have water permeability, It was not satisfactory in terms of side leaks and sanitary aspects such as sterilization.
[0006]
In view of these prior arts, the present invention is a conveyor belt with a crosspiece, which firmly joins the crosspiece and the belt base fabric without deteriorating the belt base fabric, is excellent in durability, lightweight, and suitable for draining and drying processes. A conveyor belt with a crosspiece is to be provided. In particular, it is an object of the present invention to provide a conveyor belt with a safety bar which is free from the risk of foreign matters consisting of belt components in a food conveyance process.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, in a conveyor belt with a cross, in which a plurality of crosspieces for slipping a conveyed product are attached to an outer peripheral surface of the transport belt base cloth in a lateral direction at an arbitrary interval, the belt base cloth and the crosspiece Is composed of a mesh fabric woven from synthetic resin filament warps and wefts that has air permeability and water permeability, and at the part where the crosspiece and belt base fabric are joined , a plurality of warps or wefts constituting the crosspiece are removed. At least a part of the cocoon-like warp or weft exposed by the removal is inserted into an opening portion formed between the warp and the weft constituting the belt base fabric, and at least one of the inserted warp or weft By alternately knitting the belt on both sides of the mesh structure of the belt base fabric, a transport belt with a water cross is obtained that has a water permeability in which the cross and the belt base are firmly joined without using a separate joining material. It is done. The conveyance belt with a water-permeable crosspiece according to the present invention is joined directly without using an adhesive or other bonding material when the crosspiece is attached to and fixed to the belt base fabric, and therefore there is a risk of contamination of the belt components. There is no. In addition, the mesh fabric has a large number of openings so that it has air permeability and water permeability. Particularly when used in a draining process, the mesh fabric is excellent in drainage and at the same time has excellent side leakage, Become.
[0008]
The belt base fabric and the crosspiece are preferably made of synthetic resin filaments. Considering antifouling property, rigidity, etc., it is more preferable that the yarn is composed of a monofilament yarn. The material is not particularly limited as long as it is a filament made of a synthetic resin, but polyester (PET) and polyphenylene sulfide (PPS) are preferable from the viewpoint of durability, chemical resistance, and heat resistance. This is applicable when used under high temperatures such as sterilization and drying, and is also preferable in terms of hygiene. In order to further improve the antifouling property, a fluorine-containing or fluorine-processed filament may be used.
[0009]
Moreover, it is preferable that the conveyor belt base fabric and the cross are mesh fabrics woven from warps and wefts. As the woven structure, a plain weave or single twill weave, or a double weave woven fabric such as 2/1 twill weave is preferable in terms of both water permeability and rigidity. A part of the warp or weft constituting the crosspiece body is inserted into the belt base fabric, and the crosspiece and the belt base fabric are directly joined by knitting the belt base fabric using a part of the inserted yarn. The crosspiece and the belt base fabric preferably have the same mesh structure. In addition, the mesh opening of the mesh fabric is preferably equal to or larger than the cross-sectional area of the thread to be inserted. The weaving direction is preferably the warp direction of the belt base fabric in consideration of the holding strength of the crosspieces, and the number of braids may be appropriately set depending on the weight of the conveyed product. As the number of braids increases, the holding strength of the crosspiece increases, but the time and effort of knitting also increases. Therefore, the number of braids can be set according to the required holding strength of the crosspiece. The weaving may be performed on one side or both sides of the crosspiece, but the double side weaving is preferable in consideration of the fixing property of the crosspiece. Except for the yarn to be knitted, it is preferable to cut on the back side of the belt base fabric and cut the belt base fabric so that it does not hinder the running of the belt base fabric. Furthermore, when the joining strength of a crosspiece is required, reinforcement joining may be performed by ultrasonic welding. The warp of the warp and weft is preferably 0.3 to 1.5 mm. If the wire diameter is less than 0.3 mm, the rigidity is poor, and if it exceeds 1.5 mm, weaving becomes difficult and uneconomical. A flat type may be used. What is necessary is just to select suitably according to the use conditions of a conveyance belt with a crosspiece. By constructing the conveyor belt base fabric and crosspieces from mesh fabric, for example, when used in the process of scooping up the conveyed items from the water tank, the drainage of the conveyor belt with the crosspieces in water is reduced at the same time as water drainage is good. , Less power load, energy saving and improved transport speed. Also, in the drying step after the draining step, the drying efficiency can be improved because the drainage degree is high. Moreover, the conveyance belt with a cross itself can be reduced in weight.
[0010]
It is preferable that the conveyor belt base fabric is provided with joint portions at both end portions of an end-like base fabric woven with monofilament warps and wefts, and the both end portions are connected with the joint portions to be endless. . The structure of the joint is that the weft is removed from both ends of the endless belt base fabric, and the reed warp-like warp is turned back by removing the weft. A warp loop seam structure that weaves the tip into the belt base fabric, meshes the warp loops formed at both ends of the belt base fabric, and inserts and connects the connecting core wire to the warp loop common hole formed by meshing, The spiral filaments made of synthetic resin monofilament are meshed with the warp loops, the spiral filament fixing core wires are inserted into the common holes formed by meshing, and the spiral filaments formed at both ends of the belt base fabric A spiral structure in which a connecting core wire is inserted into and connected to a spiral wire common hole formed by meshing, or a combination thereof. There. By providing such a joint portion, it is possible to remove and clean the conveyor belt with a cross if necessary, and to simplify the maintenance of the conveyor belt attaching machine with the cross and the maintenance of the conveyor belt with the cross itself.
