Description
本発明は、防塵マスクに使用する円形フィルタの製造方法に関するものである。 The present invention relates to a method for manufacturing a circular filter used in a dust mask.
防塵マスクは、浮遊粉塵の存在する人体に有害な環境下での作業に際して着用され、作業者が有害な粉塵を吸い込まないように工夫されている。そして、防塵マスクに取り付けられているフィルタは、このような環境下において、きれいな空気の呼吸を保証するために設けられており、これはパルプや繊維を抄造して得たろ紙又は不織布等からなるろ過材を折り畳んで収納ケース内に収容して使用している。 Dust masks are worn during work in an environment that is harmful to the human body where airborne dust exists, and are devised so that workers do not inhale harmful dust. And the filter attached to the dust mask is provided in order to guarantee the breathing of clean air in such an environment, and this is made of filter paper or nonwoven fabric obtained by making pulp or fiber. The filter medium is folded and stored in a storage case.
従来、この防塵マスクに使用する円形フィルタの製作方法は、ろ過材を決められた折数の面積で楕円状に展開し、カッターなどで切断し、その後、折り畳んで製作する方法が知られている(例えば、特許文献1参照。)。
上記特許文献1に開示された円形フィルタの製作方法では、折り畳んだ後の形が円形ケースに入る形になるように、展開した形が楕円状にろ過材を形成する必要があった。即ち、ロール状のろ紙から楕円状に切り抜いた後で人手で折る作業か、または、ロール状のろ紙をジグザグ状に成形した後に広げて楕円状に切り抜き、再び折り戻す作業が必要であり、人の手作業によるところが大きい。また、楕円状に切り抜くための線引き時間や、ろ過材を楕円状に正確に切断する作業が必要であり、作業性が非常に悪いという問題があった。 In the manufacturing method of the circular filter disclosed in Patent Document 1, it has been necessary to form the filter medium in an elliptical shape so that the shape after folding becomes a shape that fits into the circular case. That is, it is necessary to either manually cut the roll filter paper into an elliptical shape and then fold it manually, or after forming the roll filter paper into a zigzag shape, spread it out, cut it into an elliptical shape, and then fold it back again. This is largely due to manual work. In addition, there is a problem that the drawing time for cutting into an elliptical shape and the work of accurately cutting the filter medium into an elliptical shape are necessary, and the workability is very poor.
そこで、本発明は上記問題点を解決するためになされたもので、ろ過材を楕円状に展開することなく、かつ円形フィルタを同時に複数個製造することができる円形フィルタの製作方法を提供することを目的とする。 Accordingly, the present invention has been made to solve the above problems, and provides a method for manufacturing a circular filter that can simultaneously manufacture a plurality of circular filters without expanding the filter medium into an elliptical shape. With the goal.
上記目的を達成するために、本発明の円形フィルタの製作方法は、折り畳まれたろ過材を複数重ね合わせて型に収納する工程と、前記型に収納されたろ過材を円形に切断する工程と、前記切断されたろ過材を1つずつ分離してフィルタ収納ケースに収納する工程とを有し、前記型は、複数のろ過材を収納して折り畳んだ形状を保持するように、折り畳まれたろ過材の周縁部を保持していることを特徴とする。
In order to achieve the above object, a method for producing a circular filter of the present invention includes a step of stacking a plurality of folded filter media and storing them in a mold, and a step of cutting the filter media stored in the mold into a circle. , possess a step of storing the filter housing case by separating the cut filter medium one by one, the type, so as to hold the folded shape by housing a plurality of filtering material, folded It is characterized by holding the peripheral edge of the filter medium .
本発明の円形フィルタの製作方法によれば、全ての製造作業が、装置を使用する作業となり作業性が良い。また、所定の折数をもった所定寸法の円形フィルタが同時に複数個製造することができるので、作業効率が著しく向上する。 According to the method for manufacturing a circular filter of the present invention, all manufacturing operations become operations using the apparatus, and workability is good. In addition, since a plurality of circular filters having a predetermined number of folds and having a predetermined size can be manufactured at the same time, work efficiency is remarkably improved.
以下、図面を参照して本発明の円形フィルタの製造方法について説明する。 Hereinafter, the manufacturing method of the circular filter of this invention is demonstrated with reference to drawings.
図1は、本発明の実施形態に係る円形フィルタの製造方法の工程を示すフローチャートである。
即ち、円形フィルタの製造方法は、まず、ろ材の厚みを選定したロール状のろ紙をジグザグ状に折り形成する装置(折り機)でジグザグ状に折ったろ過材を形成する(ステップS1)。
FIG. 1 is a flowchart showing steps of a method for manufacturing a circular filter according to an embodiment of the present invention.
That is, in the manufacturing method of the circular filter, first, a filter medium folded in a zigzag shape is formed by a device (folder) that folds and forms a roll-shaped filter paper whose thickness is selected (step S1).
次に、折り畳んだろ過材を必要寸法に切断する(ステップS2)。
次に、切断した折り畳まれたろ過材を重ね合わせて多層形状にする(ステップS3)。
Next, the folded filter material is cut into necessary dimensions (step S2).
Next, the cut and folded filter media are overlapped to form a multilayer shape (step S3).
図2は、上記したステップ1〜ステップ3の工程で形成されるろ過材を示す。即ち、ロール状のろ紙5を折り機10でジグザグ状に折ったろ過材を形成し(図2(a))、折り畳んだろ過材を必要寸法に切断し(図2(b))、切断した折り畳まれたろ過材を重ね合わせて多層形状にする(図2(c))。
FIG. 2 shows the filter medium formed in the steps 1 to 3 described above. That is, a filter medium is formed by folding the roll-
次に、多層形状のろ過材を切り抜くための抜き型20に収納する(ステップS4)。
図3は、この抜き型20の形状を示す平面図である。抜き型20の外周は断面コの字状に形成されており、装着したろ過材20aの周縁部を収納保持する構造となっている。また、押さえ棒20bによってジグザグ状に折ったろ過材20aの形状がそのまま保たれている。押さえ棒20bは、抜き型20の左右の外周に摺動可能に取り付けられるもので、ろ過材20aの大きさに合わせてネジ21によって固定される。
Next, the multilayer filter medium is stored in a punching die 20 for cutting out (step S4).
FIG. 3 is a plan view showing the shape of the punching die 20. The outer periphery of the
次に、抜き型20に収納されたろ過材を回転刃(図示せず)で、円筒状に複数個切断する(ステップS5)。図3の円20cは、回転刃で切断される箇所の一例を示している。図3では1箇所の切断しか例示していないが、抜き型20に収納されたろ過材に対し無駄なく切断される。
Next, a plurality of filter media housed in the
次に、切断したろ過材を1つずつ分離して、円形フィルタの収納ケースに収納する(ステップS6)。最後に、収納ケースの内側に接着剤を入れ、ろ過材を収納ケースに固着する(ステップS7)。 Next, the cut filter media are separated one by one and stored in a circular filter storage case (step S6). Finally, an adhesive is put inside the storage case, and the filter medium is fixed to the storage case (step S7).
図4は、ステップS5で切断されたろ過材30を示し、ステップS6で1つずつ分離したろ過材30aを収納ケース31に収納するところを示している。
FIG. 4 shows the
このように、折り畳まれたろ過材を多層に堆積させた状態で抜き型20に収納し、回転刃で収納ケース31の大きさに切断することにより、一度に多数のろ過材を得ることが出来る。そして、こうして作成したろ過材を1枚ずつ分離して収納ケース31に収納して固着することにより、円形フィルタを製造することが出来る。
なお、ステップS1におけるろ過材の折数は、収納ケース31の内寸、ろ過材30aの厚さで決まる。
In this way, a large number of filter media can be obtained at a time by storing the folded filter media in a multi-layered state in the
Note that the number of filter media folds in step S1 is determined by the inner dimensions of the
上述した実施形態の円形フィルタの製造方法によれば、ろ過材はロール状のろ紙からジグザク状に折り成形する装置(折り機)で成形するため、ジグザグ状に折られた角型で連続に押し出され、所定寸法で切断される。このため、従来の楕円状のろ過材の作成作業を不要とし、所定折数をもった所定寸法の必要数量が一連の作業で完成する。また楕円状に切り抜くための線引き時間も不要となる。 According to the method for manufacturing the circular filter of the above-described embodiment, the filter medium is formed by a device (folding machine) that folds the roll filter paper into a zigzag shape, and thus is continuously extruded with a square shape folded in a zigzag shape. And cut with a predetermined dimension. For this reason, the conventional work for creating an elliptical filter medium is not required, and a required quantity of a predetermined size with a predetermined number of folds is completed in a series of operations. Moreover, the drawing time for cutting out into an ellipse is also unnecessary.
