本考案は、蓄電池用ロール状セパレータに関するもので、蓄電池の製造に際し て、巻芯に巻回保持されたセパレータを巻戻しながら極板群の製造に供される蓄 電池用ロール状セパレータに関するものである。 The present invention relates to a roll-shaped separator for a storage battery, and relates to a roll-shaped separator for a storage battery that is used for manufacturing an electrode plate group while unwinding the separator held by a winding core when manufacturing the storage battery. is there.

従来の蓄電池用ロール状セパレータは、図2に示すように、紙製の筒状巻芯1 に両面粘着テープ2を介してセパレータ3の一端を貼り付け固定して、セパレー タ3を巻芯1に巻回保持するようにしている。 As shown in FIG. 2, the conventional roll-type separator for a storage battery is configured such that one end of a separator 3 is attached and fixed to a paper-made tubular core 1 via a double-sided adhesive tape 2, and the separator 3 is attached to the core 1. I try to hold it around.
【0003】[0003]
前記蓄電池用ロール状セパレータは電池組立て工程で巻戻しながら使用される が、セパレータ3の方が巻芯1よりも両面粘着テープ2との接着性が良好なため 、電池組立て作業中に両面粘着テープ2がセパレータ3に付着した状態で巻芯1 から剥がれてしまい、この両面粘着テープ2が電池組立て装置に付着する等して 電池の組立て作業性を悪化させている。 そこで、本考案は前記両面粘着テープ2が巻芯1から剥がれることなく、セパ レータ3を両面粘着テープ2が付着することなく巻戻すことができる蓄電池用ロ ール状セパレータを提供することを目的とする。 The roll-shaped separator for a storage battery is used while being unwound in the battery assembling process. Since the separator 3 has better adhesiveness with the double-sided adhesive tape 2 than the core 1, the double-sided adhesive tape is used during the battery assembling work. 2 adheres to the separator 3 and is peeled off from the core 1, and the double-sided adhesive tape 2 adheres to the battery assembling device, which deteriorates the workability of assembling the battery. Therefore, the present invention aims to provide a roll-shaped separator for a storage battery, which can rewind the separator 3 without the double-sided adhesive tape 2 being peeled off from the winding core 1 and without the double-sided adhesive tape 2 being attached. And

本考案の蓄電池用ロール状セパレータは、かかる目的を達成するべく、巻芯に セパレータの一端を両面粘着テープを介して貼り付け固定すると共に該セパレー タを巻回保持してなる蓄電池用ロール状セパレータにおいて、前記両面粘着テー プの接着力をセパレータ側面よりも巻芯側面の方を大きくしたことを特徴とする 。 この場合、前記両面粘着テープの接着力をセパレータ側面の接着力を1とした 場合に巻芯側面の接着力を1.5倍以上にするのが好ましい。 In order to achieve such an object, the roll-type separator for a storage battery of the present invention comprises a roll-type separator for a storage battery in which one end of the separator is attached and fixed to a winding core with a double-sided adhesive tape and the separator is wound and held. In the above, the adhesive force of the double-sided adhesive tape is larger on the side surface of the winding core than on the side surface of the separator. In this case, it is preferable that the adhesive force of the side surface of the core is 1.5 times or more when the adhesive force of the side surface of the separator is 1 as the adhesive force of the double-sided adhesive tape.
【0005】 前記両面粘着テープとしては不織布、和紙、布、合成樹脂フィルム、発泡性樹 脂等からなる基材の両面にアクリル系、ゴム系等の粘着材を塗布したもの等が使 用できる。尚、基材を用いない所謂ノンキャリアタイプの両面粘着テープであっ ても構わない。 尚、両面が異なる接着力の両面粘着テープを得るには、接着力の異なる粘着材 を用いて接着力に差を設けるようにしても、或いは同じ接着力の粘着材を用い、 例えば片方の粘着材にコロナ放電処理等の表面活性化処理を施すなどして接着力 に差を設けるようにしてもよい。As the double-sided pressure-sensitive adhesive tape, a material such as a non-woven fabric, a Japanese paper, a cloth, a synthetic resin film, a foaming resin or the like coated with a pressure-sensitive adhesive such as an acrylic or rubber adhesive on both sides can be used. Incidentally, it may be a so-called non-carrier type double-sided adhesive tape which does not use a base material. In order to obtain a double-sided adhesive tape having different adhesive strengths on both sides, adhesive materials having different adhesive strengths may be used to provide different adhesive strengths, or adhesive materials having the same adhesive strength may be used. The materials may be subjected to surface activation treatment such as corona discharge treatment to provide a difference in adhesive strength.
【0006】[0006]
本考案の蓄電池用ロール状セパレータにおいては、前記両面粘着テープの接着 力をセパレータ側面よりも巻芯側面の方を大きくしたので、セパレータの方が巻 芯よりも両面粘着テープとの接着性が良好であるにもかかわらず、両面粘着テー プが巻芯から剥がれてセパレータに付着することなくセパレータを巻芯から巻戻 せる。従って、両面粘着テープが電池組立て装置に付着する等して電池の組立て 作業性を悪化させることがない。 In the roll-shaped separator for storage battery of the present invention, the adhesive strength of the double-sided adhesive tape on the side surface of the core is larger than that on the side surface of the separator, so that the separator has better adhesiveness to the double-sided adhesive tape than the core. However, the separator can be rewound from the core without the double-sided adhesive tape peeling off from the core and adhering to the separator. Therefore, the double-sided adhesive tape does not adhere to the battery assembling device and the workability of assembling the battery is not deteriorated.

A roll-shaped separator for use was prepared. When the roll-shaped separator for a storage battery thus configured was used to actually assemble a storage battery, no peeling of the separator from the winding core was observed, as in Examples 1 and 2. In the first to third embodiments, the ribbed surface of the separator is attached to the double-sided adhesive tape side, but the flat surface without ribs is attached to the double-sided adhesive tape side. Also obtained similar results.
