Abstract
Description
この発明は、使用済みテニスボールの簡易再生方法に関する。 The present invention relates to a simple reproduction method for used tennis balls.
従来、テニスボールは、その使用頻度によって外皮の表面が磨耗してしまったり、あるいは内部の空気も抜けてしまったりして、テニスボールとしての機能を失ってしまい、使用済みなってしまう。 Conventionally, a tennis ball is worn out on the surface of the outer skin depending on the frequency of use, or the air inside is lost and the function as a tennis ball is lost and used.
そして、この使用済みテニスボールは、産業廃棄物として処理されるものであり、資源の無駄となっている。そのため、この使用済みテニスボールを、練習用ボールに再生して利用することが考えられる。例えば、特許文献1のように。
And this used tennis ball is processed as industrial waste and is a waste of resources. Therefore, it can be considered that this used tennis ball is regenerated and used as a practice ball. For example, as in
しかし、使用済みテニスボールを再生するためには、外皮の溝部に未加硫ゴムを塗り、金型に入れて加硫するものであり、そのための大がかりな設備のため、その費用も大変であった。例えば、特許技術文献2のように。
そのため、使用済みテニスボールを、大がかりな設備を必要とせず主婦等の手作業の内職で簡易に再生できることが望ましい。
However, in order to recycle used tennis balls, unvulcanized rubber is applied to the groove of the outer shell and vulcanized by placing it in a mold. It was. For example, as in
Therefore, it is desirable that the used tennis ball can be easily regenerated by a housework or other manual job without requiring large-scale equipment.
そこで、発明が解決しようとする課題は、使用済みテニスボールを、簡易に練習用ボールに再生して、全国のテニス場や学校のテニス部等で安価に使用すると共に、資源の再利用が可能であり、しかも、よい環境の中で再生作業を行うことのできる使用済みテニスボールの簡易再生方法を開発・提供することにある。 Therefore, the problem to be solved by the invention is that a used tennis ball can be easily regenerated as a practice ball and used inexpensively at tennis courts and tennis clubs nationwide, and resources can be reused. In addition, another object is to develop and provide a simple method for playing back used tennis balls that can be played back in a good environment.
この発明による課題を解決するための手段としては、新しい2枚の外皮とラテックス系の糊、蒸気、アイロン等を用いて、簡単に再生のできる使用済みテニスボールの簡易再生方法を開発・提供するものである。 As a means for solving the problems according to the present invention, a simple method for regenerating used tennis balls that can be easily regenerated using two new outer shells and latex glue, steam, iron, etc. is developed and provided. Is.
この発明によると、未加硫ゴムを加硫させるために入れる複数の金型等を必要とせず、極めて原始的な方法によって、使用済みテニスボールの再生が、簡単に行えるものであり、内部への充填も、市販の空気入れを使用することにより、簡単に行える等極めて有益なる効果を奏するものである。 According to the present invention, it is possible to easily recycle a used tennis ball by a very primitive method without requiring a plurality of molds or the like for vulcanizing unvulcanized rubber. In addition, the use of a commercially available air can provide an extremely beneficial effect such as simple filling.
以下、この発明の好適な実施の形態について述べると、使用済みテニスボールの外皮を剥がす工程と、新たな外皮を貼る工程と、該新たな外皮がボールに堅牢に接着する工程からなる使用済みテニスボールの再生方法である。 Hereinafter, a preferred embodiment of the present invention will be described. The used tennis ball includes a step of peeling a used tennis ball, a step of applying a new skin, and a step of firmly bonding the new skin to the ball. This is a method of playing a ball.
そこで、この発明の一実施例を図1,図2に基づいて詳細に説明すると、
使用済みテニスボール(1)に、所定時間、蒸気を当てるA工程と、該蒸気を当てた該ボール(1)の古い外皮(2a)(2b)を剥ぐB工程と、これら剥いだ古い外皮(2a,2b)に代えて貼る、新しい外皮(2a′,2b′)の裏面に、それぞれ接着剤(3)を塗るC工程と、前記古い外皮(2a)(2b)を剥ぐことによって生じた前記ボール(1)表面のシーム(X)に沿って、2枚の新しい外皮(2a′)(2b′)のうち、その一枚を貼るD工程と、前記ボール(1)のシーム(X)部分であって、且つ、前記新しい外皮(2a′又は2b′)の縁に沿って適宜な幅の紐(4)を仮止め接着するE工程と、
該紐(4)に沿って、他の一枚の新しい外皮(2a′又は2b′)をボール(1)に貼るF工程と、前記紐(4)を剥がすことにより、2枚の外皮(2a′)(2b′)間に溝のように生じたシーム(X)に水性ゴム等の接着剤(5)を塗布するG工程と、ボール(1)表面のシーム(X)に接着剤(5)を塗布した部分と、裏面に塗布された前記接着剤(3)を塗布した2枚の新しい外皮(2a′)(2b′)のそれぞれ外周とを、作業台等の板材(図示せず)に軽く押圧するか、あるいは、熱を有する,例えばアイロン等の板材(Y)に圧接させるH工程と、前記ボール(1)内部に、チッソを含むガス、あるいはチッソを含むエアーを、必要量ほど充填するI工程との組み合わせからなることを特徴とする使用済みテニスボールの簡易再生方法から構成されるものである。
An embodiment of the present invention will be described in detail with reference to FIGS.
A step of applying steam to the used tennis ball (1) for a predetermined time, a step B of removing the old outer skin (2a) (2b) of the ball (1) applied with the steam, and the old outer skin ( 2a, 2b), instead of applying the adhesive (3) on the back of the new outer skin (2a ', 2b'), and the old outer skin (2a) (2b) D step of pasting one of two new outer skins (2a ') (2b') along the seam (X) on the surface of the ball (1), and the seam (X) portion of the ball (1) And E step of temporarily adhering a string (4) of an appropriate width along an edge of the new outer skin (2a 'or 2b');
Along with the string (4), another step of attaching a new outer skin (2a 'or 2b') to the ball (1) and peeling off the string (4), two outer skins (2a ′) (2b ′) G step of applying an adhesive (5) such as water-based rubber to the seam (X) generated like a groove between the two (2b ′), and adhesive (5 to the seam (X) on the surface of the ball (1) ) And the outer periphery of each of the two new outer skins (2a ′) and (2b ′) coated with the adhesive (3) coated on the back surface, a plate material (not shown) such as a work table. The H process which is pressed lightly or has a heat contact with a plate material (Y) such as an iron, and the ball (1) contains a gas containing nitrogen or air containing nitrogen. A simple used tennis ball characterized by a combination with the filling I process It is those composed of the raw process.
尚、使用済みテニスボール(1)に、蒸気を当てる時間は、おおよそ1分間程度であり、2枚の新しい外皮(2a′)(2b′)は、同一の形状であり、その素材の一例としては、羊毛と合成樹脂との混紡不織布である。 It should be noted that the time for which steam is applied to the used tennis ball (1) is about one minute, and the two new outer skins (2a ′) and (2b ′) have the same shape. Is a blended nonwoven fabric of wool and synthetic resin.
また、古い外皮(2a,2b)は、ニッパー等の工具を使用して剥がせば、いとも簡単に剥がせるものである。 Further, the old outer skin (2a, 2b) can be easily peeled off by using a tool such as a nipper.
そして、ボール(1)に新しい外皮(2a′,2b′)を貼り着けることにより、ボールの表面が完成しても、ボール内部に空気圧が不足している場合には、チッソを含むガス、あるいはチッソを含むエアーを空気入れ(Z)を用いて充填することができるものである。 Then, by attaching a new skin (2a ', 2b') to the ball (1), if the air pressure is insufficient inside the ball even if the surface of the ball is completed, a gas containing nitrogen or The air containing nitrogen can be filled using an air pump (Z).
この発明の使用済みテニスボールの簡易再生方法の製造技術を確立し、実施・販売することにより、産業上利用できるものである。 By establishing, implementing and selling a manufacturing method of a simple method for recycling used tennis balls according to the present invention, it can be used industrially.
