The accommodation space 21S is a space portion formed by hollowing out the shaft-like member 21 when forming the groove forming portion 21G.

図８（ａ），（ｂ）において、軸状部材２１の両端の端部壁２１Ｂには溝部２１ｍの端部開口２１Ｄが形成されている。一方、押し込み部材２２の両端部には、軸状部材２１に取り付けられた状態で軸状部材２１の外側から内側へ向けて狭まる形状の斜面部２２Ｌが形成されている（図３（ａ）も参照）。押し込み部材２２が軸状部材２１に完全に挿入された状態では、押し込み部材２２の斜面部２２Ｌの一部が端部開口２１Ｄから溝部２１ｍの外方へ露出する。   8 (a) and 8 (b), end openings 21D of the groove 21m are formed in the end walls 21B at both ends of the shaft-shaped member 21. On the other hand, on both end portions of the push-in member 22 are formed slope portions 22L that are narrowed from the outside to the inside of the shaft-like member 21 in a state of being attached to the shaft-like member 21 (see FIG. 3A as well). reference). In a state where the pushing member 22 is completely inserted into the shaft-like member 21, a part of the inclined surface portion 22L of the pushing member 22 is exposed to the outside of the groove portion 21m from the end opening 21D.

図３（ａ），（ｂ）及び図８（ａ）において、軸状部材２１の両端部それぞれには一対の係合溝２１Ｃが設けられている。軸状部材２１を筐体１１に取り付けるときには、軸状部材２１の両端の係合溝２１Ｃを、一対の円筒体支持部１４ｂそれぞれが備えるピン部材（図示せず）に係合させる。   3A, 3 </ b> B, and 8 </ b> A, a pair of engaging grooves 21 </ b> C are provided at both ends of the shaft-like member 21. When attaching the shaft-shaped member 21 to the housing 11, the engaging grooves 21C at both ends of the shaft-shaped member 21 are engaged with pin members (not shown) provided in each of the pair of cylindrical body support portions 14b.

クリーニング機構１Ｂによるマスククリーニング作業の前準備では、作業者は、ペーパーロール１２Ｒと軸状部材２１を筐体１１に取り付ける。ペーパーロール１２Ｒの筐体１１への取り付けは、ペーパーロール１２Ｒに挿通した軸心部材１３ａの両端を一対の軸心部材支持部１３ｂに支持させることによって行う。軸状部材２１の筐体１１への取り付けは上述の要領で行う。   In preparation for the mask cleaning operation by the cleaning mechanism 1 </ b> B, the operator attaches the paper roll 12 </ b> R and the shaft-shaped member 21 to the housing 11. The paper roll 12R is attached to the housing 11 by supporting both ends of the shaft member 13a inserted through the paper roll 12R with a pair of shaft member support portions 13b. The shaft member 21 is attached to the housing 11 in the manner described above.

軸状部材２１は、溝部２１ｍ内に押し込み部材２２が挿入された状態において、回転中心軸２１Ｘ回りの偏芯がないように重量バランスがとられている。このため、溝部２１ｍに押し込み部材２２が挿入されていない状態で軸状部材２１を水平面に載置すると、溝部２１ｍは上方を向く。したがって、両端部が一対の円筒体支持部１４ｂに支持された状態では、軸状部材２１は溝部２１ｍを上方に向けた姿勢となっている。   The shaft-like member 21 is weight balanced so that there is no eccentricity around the rotation center shaft 21X in a state where the pushing member 22 is inserted into the groove 21m. For this reason, when the shaft-like member 21 is placed on a horizontal surface in a state where the pushing member 22 is not inserted into the groove portion 21m, the groove portion 21m faces upward. Therefore, in a state where both end portions are supported by the pair of cylindrical body support portions 14b, the shaft-like member 21 is in a posture with the groove portion 21m facing upward.

作業者は、ペーパーロール１２Ｒと軸状部材２１を筐体１１内に取り付けたら、ペーパーロール１２Ｒからペーパー部材１２を引き出す。そして、引き出したペーパー部材１２の一部（端部）を、軸状部材２１の溝部２１ｍの上方に位置させる（図３（ａ））。このときペーパー部材１２は、幅方向の両端部が溝部２１ｍの両端部よりも内側に位置するようにする（図３（ａ））。   When the operator attaches the paper roll 12R and the shaft-shaped member 21 in the housing 11, the operator pulls out the paper member 12 from the paper roll 12R. Then, a part (end portion) of the drawn paper member 12 is positioned above the groove portion 21m of the shaft-like member 21 (FIG. 3A). At this time, the paper member 12 is configured such that both end portions in the width direction are positioned inside the both end portions of the groove portion 21m (FIG. 3A).

上記のようにしてペーパーロール１２Ｒの一部を軸状部材２１の溝部２１ｍの上方に位置させたら、軸状部材２１の溝部２１ｍに、押し込み部材２２を、ペーパー部材１２の上方から挿入する。この挿入の過程で押し込み部材２２はペーパー部材１２を溝部２１ｍ内に押し込むので、押し込み部材２２が固定手段２３によって軸状部材２１に固定されると、ペーパー部材１２は軸状部材２１に取り付けられた状態となる（図９）。これにより前準備が完了し、クリーニング機構１Ｂによるマスククリーニング作業が可能となる。   When a part of the paper roll 12R is positioned above the groove 21m of the shaft-shaped member 21 as described above, the pushing member 22 is inserted into the groove 21m of the shaft-shaped member 21 from above the paper member 12. In this insertion process, the pushing member 22 pushes the paper member 12 into the groove portion 21m. Therefore, when the pushing member 22 is fixed to the shaft member 21 by the fixing means 23, the paper member 12 is attached to the shaft member 21. A state is reached (FIG. 9). Thus, the preparation is completed, and the mask cleaning work by the cleaning mechanism 1B becomes possible.

マスククリーニング作業では、クリーニングヘッド１５を上昇させてペーパー部材１２を押し上げ、そのペーパー部材１２の押し上げた部分（クリーニング部位と称する）をマスク３の下面に接触させる。そして、図示しない移動機構によってクリーニング機構１Ｂの全体を水平方向に移動させる。これによりペーパー部材１２がマスク３の下面で摺動し、マスク３の下面に付着しているペーストＰｓｔがペーパー部材１２によって拭き取られる。   In the mask cleaning operation, the cleaning head 15 is raised to push up the paper member 12, and the pushed-up portion (referred to as a cleaning site) of the paper member 12 is brought into contact with the lower surface of the mask 3. Then, the entire cleaning mechanism 1B is moved in the horizontal direction by a moving mechanism (not shown). As a result, the paper member 12 slides on the lower surface of the mask 3, and the paste Pst adhering to the lower surface of the mask 3 is wiped off by the paper member 12.

マスククリーニング作業によってクリーニング部位が汚れた場合には、駆動モータ１４ｃを作動させて軸状部材２１を回転中心軸２１Ｘ回りに一定量回転させる。これによりペーパー部材１２が軸状部材２１に巻き付けられ、ペーパー部材１２のクリーニングヘッド１５により押し上げられた部分、すなわちクリーニング部位がペーパー部材１２の新しい領域に更新される。   When the cleaning site is contaminated by the mask cleaning operation, the drive motor 14c is operated to rotate the shaft-shaped member 21 by a certain amount around the rotation center axis 21X. As a result, the paper member 12 is wound around the shaft-shaped member 21, and the portion pushed up by the cleaning head 15 of the paper member 12, that is, the cleaning site is updated to a new region of the paper member 12.

ペーパー部材１２の巻き取りが進んでペーパー部材供給部１３からのペーパー部材１２がなくなった（ペーパー部材供給部１３からペーパー部材１２が分離した）場合には、使用済みのペーパー部材１２が巻き付けられた円筒体１４ａを筐体１１から取り外す。そして、円筒体１４ａをペーパー部材１２の巻き取り時とは反対の方向に回転させて、円筒体１４ａからペーパー部材１２を剥がす。これにより軸状部材２１に取り付けた押し込み部材２２が露出したら、押し込み部材２２を軸状部材２１から取り外す。   When the winding of the paper member 12 has progressed and the paper member 12 from the paper member supply unit 13 has disappeared (the paper member 12 has been separated from the paper member supply unit 13), the used paper member 12 has been wound. The cylindrical body 14a is removed from the housing 11. Then, the cylindrical body 14a is rotated in a direction opposite to that when the paper member 12 is wound, and the paper member 12 is peeled off from the cylindrical body 14a. Thus, when the pushing member 22 attached to the shaft-like member 21 is exposed, the pushing member 22 is removed from the shaft-like member 21.

押し込み部材２２の軸状部材２１からの取り外しは、摘み部２２ａを引き上げることによって行う。この場合、摘み部２２ａが押し込み部材２２の端部側に寄って設けられているほど、小さい力で押し込み部材２２を軸状部材２１から取り外すことができる。或いは、上記のように摘み部２２ａを引き上げる代わりに、図１０に示すように、軸状部材２１の端部から指Ｆｇを差し入れ、軸状部材２１の端部開口２１Ｄから露出している押し込み部材２２の斜面部２２Ｌを軸状部材２１の半径方向外方に押し上げるようにしてもよい。   The pushing member 22 is removed from the shaft-like member 21 by pulling up the knob 22a. In this case, the pusher member 22 can be removed from the shaft-like member 21 with a smaller force as the knob 22 a is provided closer to the end of the pusher member 22. Alternatively, instead of pulling up the knob 22a as described above, as shown in FIG. 10, a finger Fg is inserted from the end of the shaft-shaped member 21, and the pushing member exposed from the end opening 21D of the shaft-shaped member 21 The inclined surface portion 22L of 22 may be pushed up outward in the radial direction of the shaft-shaped member 21.

以上説明したように、本実施の形態におけるスクリーン印刷装置１では、軸状部材２１の溝部２１ｍに押し込み部材２２が挿入される際にペーパー部材１２の一部が溝部２１ｍ内に押し込まれ、押し込み部材２２は固定手段２３によって軸状部材２１に固定される。これによりペーパー部材１２は軸状部材に対してしっかりと固定され、軸状部材２１から外れてしまうことがない。このため、本実施の形態におけるスクリーン印刷装置１によれば、ペーパー部材１２を安定的に巻き取ってマスク３のクリーニングをスムーズに行うことができる。   As described above, in the screen printing apparatus 1 according to the present embodiment, when the pushing member 22 is inserted into the groove portion 21m of the shaft-like member 21, a part of the paper member 12 is pushed into the groove portion 21m. 22 is fixed to the shaft-shaped member 21 by the fixing means 23. As a result, the paper member 12 is firmly fixed to the shaft-shaped member and does not come off the shaft-shaped member 21. For this reason, according to the screen printing apparatus 1 in this Embodiment, the paper member 12 can be wound up stably and the mask 3 can be cleaned smoothly.

なお、上述の例では、軸状部材２１にペーパー部材１２を取り付ける工程を、ペーパーロール１２Ｒを支持した軸心部材１３ａと軸状部材２１が既に筐体１１に取り付けられている状態で説明したが、上記工程を机上で行い、その後、ペーパー部材１２で繋がった状態の軸心部材１３ａと軸状部材２１（円筒体１４ａ）を筐体１１に取り付けるようにしてもよい。   In the above-described example, the process of attaching the paper member 12 to the shaft-like member 21 has been described in a state where the shaft-center member 13a supporting the paper roll 12R and the shaft-like member 21 are already attached to the housing 11. The above steps may be performed on a desk, and then the shaft member 13a and the shaft member 21 (cylindrical body 14a) connected by the paper member 12 may be attached to the housing 11.

ペーパー部材を安定的に巻き取ってマスクのクリーニングをスムーズに行うことができるスクリーン印刷装置を提供する。   Provided is a screen printing apparatus capable of stably winding a paper member and smoothly cleaning a mask.
