Description

この発明は、メッキ処理を行うメッキ用バレル装置に関する。   The present invention relates to a plating barrel apparatus that performs a plating process.

電子部品等、寸法の小さい被メッキ物であるワークにメッキを施すものの1つに、ワークが収納されたバレルと、バレル内に設けられた電極とを備え、バレルをメッキ液に浸漬し、メッキ液内の電極と、バレル内の電極間に電圧を印加するとともに、バレル軸と同一軸心又はバレル軸に対して傾斜した回転軸回りにバレルを回転駆動させることにより、バレル内のワークに対してメッキ処理を行うメッキ用バレル装置が従来公知である。   One of the parts to be plated, such as electronic parts, to be plated is equipped with a barrel in which the work is stored and an electrode provided in the barrel. The barrel is immersed in a plating solution and plated. A voltage is applied between the electrode in the liquid and the electrode in the barrel, and the barrel is rotationally driven around the same axis as the barrel axis or a rotation axis inclined with respect to the barrel axis. Conventionally, a plating barrel apparatus for performing plating is known.

また、このようなメッキ用バレル装置の一種として、バレル軸上で対向する一対の対向パネルを、バレル軸回りに並べられた複数の棒状の連結フレームによって連結固定することにより、角柱状のバレルフレームを構成し、隣合う連結フレームの対向面に、バレル軸方向に沿って延びる係止溝をそれぞれ形成し、隣合う連結フレーム間に嵌め込まれる周壁パネルを設け、隣合う連結フレーム間への周壁パネルの嵌め込みにあたって、周壁パネルの連結フレーム側両端部を、該隣合う連結フレームの係止溝にそれぞれ嵌合して挿入した特許文献1に示すメッキ用バレル装置が公知になっている。   In addition, as a kind of such a barrel apparatus for plating, a pair of opposed panels opposed on the barrel shaft are connected and fixed by a plurality of rod-shaped connection frames arranged around the barrel shaft, so that a prismatic barrel frame is obtained.

上記文献のメッキ用バレル装置は、バレルフレームを構成する棒状の連結フレームに形成された係止溝によって、周壁パネルがバレルフレームに取付けられるため、周壁パネルを、バレルフレーム側に取付けるための部材を別途用意する必要が無く、部品点数が減少して、コストを低く抑えることが可能になる一方で、係止溝に挿入される周壁パネル端部と、該係止溝との間に隙間が形成され、この隙間によって、周壁パネルにガタが生じ、これによって、メッキ処理の質が低下する場合がある他、強度も低下する。そして、周壁パネルを、バレルフレームに接着等できない場合、この問題は特に顕著になる。   Since the peripheral wall panel is attached to the barrel frame by the locking groove formed in the rod-shaped connecting frame constituting the barrel frame, the plating barrel device of the above document is provided with a member for attaching the peripheral wall panel to the barrel frame side. There is no need to prepare separately, the number of parts can be reduced, and the cost can be kept low, while a gap is formed between the end of the peripheral wall panel inserted into the locking groove and the locking groove. In addition, the gap causes play in the peripheral wall panel, which may reduce the quality of the plating process and also reduce the strength. This problem becomes particularly significant when the peripheral wall panel cannot be bonded to the barrel frame.

本発明は、方形状の周壁パネルの両端部を、隣合う連結フレームの係止溝にそれぞれ挿入することにより、隣合う連結フレームの間に周壁パネルを嵌め込んだメッキ用バレル装置において、周壁パネルのガタを低減させ、メッキ処理の質を向上させるとともに、取付け強度も向上させたメッキ用バレル装置を提供することを課題としている。   The present invention relates to a plating barrel apparatus in which a peripheral wall panel is fitted between adjacent connection frames by inserting both end portions of a rectangular peripheral wall panel into a locking groove of an adjacent connection frame. It is an object of the present invention to provide a plating barrel apparatus that can reduce the backlash, improve the quality of the plating process, and improve the mounting strength.

The peripheral wall panel 7 is provided, and when the peripheral wall panel 7 is fitted between the adjacent connecting frames 3A and 3B, both ends of the peripheral wall panel 7 on the side of the connecting frames 3A and 3B are connected to the engaging grooves of the adjacent connecting frames 3A and 3B. 22 and 22 are plating barrel devices that are fitted and inserted respectively into the peripheral wall panel 7 inserted into the locking groove 22 when the peripheral wall panel 7 is fitted between the connecting frames 3A and 3B. In this case, a restricting portion for restricting the movement of the peripheral wall panel 7 in a direction in which the surfaces deviate from each other is provided at the contact or proximity surface that forms the boundary between the end portion of the lug 7 and the locking groove 22. .

第4に、上記境界にバレル軸Y方向に沿う挿入部23が形成されるように、前記係止溝22に挿入された周壁パネル7端部及び係止溝22の互いに接触又は近接する面に、バレル軸Y方向に沿う凹部7a,22aをそれぞれ形成し、周壁パネル7の連結フレーム3A,3B間への嵌め込み時に挿入部23に嵌合して挿入される規制棒24と、該挿入部23とによって、前記規制部を構成したことを特徴としている。   Fourth, the peripheral wall panel 7 end inserted into the locking groove 22 and the surface of the locking groove 22 in contact with each other or close to each other so that the insertion portion 23 along the barrel axis Y direction is formed at the boundary. The control rod 24 is formed by forming recesses 7a and 22a along the barrel axis Y direction, and being fitted into the insertion portion 23 when the peripheral wall panel 7 is fitted between the connecting frames 3A and 3B. And the restriction part is configured.

第5に、挿入部23が断面視円形をなすように、前記周壁パネル7端部及び係止溝22の凹部7a,22aを、円弧面状に形成し、規制棒24を丸棒状に形成したことを特徴としている。   Fifth, the end portion of the peripheral wall panel 7 and the recesses 7a and 22a of the locking groove 22 are formed in an arcuate shape so that the insertion portion 23 has a circular shape in cross section, and the regulation rod 24 is formed in a round bar shape. It is characterized by that.

第6に、前記周壁パネル7端部及び係止溝22の凹部7a,22aを、それぞれ同一形状の半円弧面状に形成したことを特徴としている。   Sixth, the end portion of the peripheral wall panel 7 and the recesses 7a and 22a of the locking groove 22 are formed in the same shape of semicircular arc surface.

第7に、係止溝22を連結フレーム3A,3Bの一端から他端に至る長さに形成し、係止溝22の全体に亘って凹部22aを形成したことを特徴としている。   Seventhly, the locking groove 22 is formed to have a length from one end to the other end of the coupling frames 3A and 3B, and the recess 22a is formed over the entire locking groove 22.

第8に、周壁パネル7の全長を連結フレーム3A,3Bの全長と略同一に設定し、凹部7aを周壁パネル7の全体方向全体に亘って形成したことを特徴としている。   Eighth, the entire length of the peripheral wall panel 7 is set to be substantially the same as the total length of the connection frames 3A and 3B, and the concave portion 7a is formed over the entire direction of the peripheral wall panel 7.

第9に、挿入部23の全長と、規制棒24の全長とを、略同一長さに設定したことを特徴としている。   Ninth, the total length of the insertion portion 23 and the total length of the regulating rod 24 are set to be substantially the same length.

第10に、前記係止溝22に挿入された周壁パネル7端部及び係止溝22の互いに接触又は近接する面に、凹凸嵌合する嵌合部7b,22bをそれぞれ形成し、周壁パネル7及び係止溝22の嵌合部7b,22bによって、前記規制部を構成したことを特徴としている。   Tenth, fitting portions 7b and 22b that are concavo-convexly fitted are formed on the surfaces of the end portion of the peripheral wall panel 7 inserted into the locking groove 22 and the surface of the locking groove 22 that are in contact with each other or close to each other. Further, the fitting portion 7b, 22b of the locking groove 22 constitutes the restriction portion.

上記構成によれば、周壁パネルの連結フレーム間への嵌め込み時、係止溝に挿入された周壁パネル端部と、該係止溝との境界をなす互いの接触又は近接面に、該面同士がずれる方向への周壁パネルの移動を規制する規制部を設けたため、該移動の規制によって、周壁パネルのガタが抑制され、メッキ処理の質が向上し、取付け強度も高まる。   According to the above configuration, when the peripheral wall panel is fitted between the connecting frames, the end portions of the peripheral wall panel inserted in the locking groove and the mutual contact or proximity surface that forms a boundary between the locking groove, Since the restricting portion for restricting the movement of the peripheral wall panel in the direction of shifting is provided, the restriction of the movement suppresses the play of the peripheral wall panel, improves the quality of the plating process, and increases the mounting strength.

また、前記規制部が、係止溝の側面に形成されれば、該挿入部に挿入された規制棒によって、係止溝に両端部が係止された周壁パネルにおける係止溝窪み方向の移動が規制される。このため、周壁パネルの連結フレーム側両端部の距離と、向い合う係止溝の底の間の距離とが略同一になるように、係止溝のサイズを高精度で形成する必要無く、上記方向への周壁パネルのガタを効率的に防止できる。   Further, if the restricting portion is formed on the side surface of the engaging groove, the restricting rod inserted into the inserting portion moves the engaging groove in the engaging groove recess direction in the peripheral wall panel in which both end portions are engaged with the engaging groove.

For this reason, it is not necessary to form the size of the locking groove with high accuracy so that the distance between the both ends of the connecting wall side of the peripheral wall panel and the distance between the bottoms of the locking grooves facing each other is substantially the same. The backlash of the peripheral wall panel in the direction can be effectively prevented.

また、上記境界にバレル軸方向に沿う挿入部が形成されるように、前記係止溝に挿入された周壁パネル端部及び係止溝の互いに接触又は近接する面に、バレル軸方向に沿う凹部をそれぞれ形成し、周壁パネルの連結フレーム間への嵌め込み時に挿入部に嵌合して挿入される規制棒と、該挿入部とによって、高精度な成形を要すること無く、規制部を構成可能であり、コスト低減と、周壁パネルのガタの低減とを、両立可能になる。   Further, a recess along the barrel axial direction is formed on the surface of the peripheral wall panel end inserted into the locking groove and the surface of the locking groove that are in contact with or close to each other so that an insertion portion along the barrel axial direction is formed at the boundary. The restriction portion can be configured without requiring high-precision molding by the restriction rod inserted into the insertion portion when the peripheral wall panel is fitted between the connecting frames and the insertion portion. Yes, both cost reduction and play of the peripheral wall panel can be reduced.

さらに、挿入部が断面視円形をなすように、前記周壁パネル端部及び係止溝の凹部を、円弧面状に形成し、規制棒を丸棒状に形成すれば、規制棒の軸回りの向きを合せること無く、該挿入棒を挿入部に嵌合挿入可能であり、作業性が向上する。   Further, if the peripheral wall panel end and the recess of the locking groove are formed in an arcuate surface shape so that the insertion portion is circular in cross section, and the restriction rod is formed in a round shape, the orientation of the restriction rod around the axis The insertion rod can be fitted and inserted into the insertion portion without matching, and workability is improved.

なお、前記係止溝に挿入された周壁パネル端部及び係止溝の互いに接触又は近接する面に、凹凸嵌合する嵌合部をそれぞれ形成し、周壁パネル及び係止溝の嵌合部によって、前記規制部を構成すれば、周壁パネル及び係止溝以外に別途部材を設ける必要が無く、部品点数を減らすことが可能になる。   In addition, a fitting portion for engaging the concave and convex portions is formed on the surface of the peripheral wall panel inserted into the locking groove and the surface of the locking groove in contact with each other or close to each other, and the fitting portion of the peripheral wall panel and the locking groove is used. If the restricting portion is configured, it is not necessary to separately provide members other than the peripheral wall panel and the locking groove, and the number of parts can be reduced.

以下図示する例に基づき本発明の実施形態について説明する。
図1乃至3は、本発明を適用したメッキ用バレル装置の要部構成を示す側断面図、平面図及び正面図である。メッキ用バレル装置は、角柱状(図示する例では、六角柱状)に形成されたバレル1と、バレル1内に設けられた電極であるカソード(図示しない)と、該バレル1を真横方向の回転軸X回りに回転自在に支持する支持機構(図示しない)と、バレル1の一部又は全部が浸漬されるメッキ液内に設けられた電極であるアノード(図示しない)と、カソードとアノードとの間に電圧を印加する電源装置(図示しない)とを備えている。
Embodiments of the present invention will be described below based on the illustrated example.
1 to 3 are a side cross-sectional view, a plan view, and a front view showing a main configuration of a plating barrel apparatus to which the present invention is applied. The plating barrel apparatus includes a barrel 1 formed in a prismatic shape (in the illustrated example, a hexagonal prism shape), a cathode (not shown) that is an electrode provided in the barrel 1, and the barrel 1 is rotated in a lateral direction. A support mechanism (not shown) that supports the shaft X so as to be rotatable, an anode (not shown) that is an electrode provided in a plating solution in which a part or all of the barrel 1 is immersed, and a cathode and an anode. And a power supply device (not shown) for applying a voltage therebetween.

バレル1は、メッキ液に浸漬しても腐食し難く且つ電気を通さない絶縁体である合成樹脂(さらに具体的には、ポリプロピレン)等によって各種部材が構成されている。なお、図示する例では、この角柱状のバレル1の軸であるバレル軸Yは、上述した回転軸Xと同一軸心となるが、回転軸Xに対して、バレル軸Yを所定角度だけ傾斜させてもよい。   The barrel 1 includes various members made of a synthetic resin (more specifically, polypropylene) that is an insulator that does not corrode even when immersed in a plating solution and does not conduct electricity. In the illustrated example, the barrel axis Y that is the axis of the prismatic barrel 1 is the same axis as the rotation axis X described above, but the barrel axis Y is inclined by a predetermined angle with respect to the rotation axis X. You may let them.

内部に微小サイズの被メッキ物であるワーク(図示しない)を収納したバレル1を、メッキ液に浸漬させ、アノードとカソードの間に電圧を印加し、回転軸X回りに回転駆動させならが、ワークに対してメッキ処理を行う。このように、メッキ処理中に、バレル1を回転駆動させることにより、ワークがバレル1内で攪拌され、ワーク同士の重なりや、貼付きが防止されるため、質の良いメッキ処理を行うことが可能になる。   If the barrel 1 containing a workpiece (not shown) that is an object to be plated inside is immersed in the plating solution, a voltage is applied between the anode and the cathode, and it is driven to rotate around the rotation axis X, Plate the workpiece. Thus, by rotating the barrel 1 during the plating process, the workpieces are agitated in the barrel 1 and the workpieces are prevented from being overlapped or stuck together. It becomes possible.

次に、図1乃至6に基づいて、バレル1の構成を詳述する。
バレル1は、バレル軸Y上で平行に対向する一対のサイドフレーム(対向パネル)2,2と、一対のサイドフレーム2,2間に架設固定され且つバレル軸Yの軸回りに所定間隔毎に3つ以上(図示する例では6つ)配置された棒状の横フレーム(連結フレーム)3A,3A,3B,3B,3B,3Bとによって、角柱状のバレルフレーム4を構成しており、角柱状をなすバレルフレーム4における複数の側面の1つに開口パネル6が嵌め込み固定されるとともに、その他の側面にそれぞれ各別に周壁パネル7が嵌め込み固定されている。
Next, the configuration of the barrel 1 will be described in detail with reference to FIGS.
The barrel 1 is constructed and fixed between a pair of side frames (opposite panels) 2 and 2 facing each other in parallel on the barrel axis Y, and between the pair of side frames 2 and 2, and around the axis of the barrel axis Y at predetermined intervals. A rectangular columnar barrel frame 4 is constituted by three or more (six in the illustrated example) bar-shaped horizontal frames (connecting frames) 3A, 3A, 3B, 3B, 3B, 3B, which are prismatic. An opening panel 6 is fitted and fixed to one of a plurality of side surfaces of the barrel frame 4 forming the above, and a peripheral wall panel 7 is fitted and fixed to each of the other side surfaces.

また、この開口パネル6の開口部分からワークの出し入れが行われる他、開口パネル6への閉塞蓋11の着脱によって、この開口部分が開閉される。閉塞蓋11は、合成樹脂製部材によって一体的に成形され、多数の円状の孔が穿設されることにより構成される方形状の通液窓11aが複数設けられている。   Further, the workpiece is taken in and out from the opening portion of the opening panel 6, and the opening portion is opened and closed by attaching and detaching the closing lid 11 to the opening panel 6. The closing lid 11 is integrally formed of a synthetic resin member, and is provided with a plurality of rectangular liquid flow windows 11a configured by forming a large number of circular holes.

ちなみに、開口側横フレーム3Aには、該開口パネル6の開口面に対して垂直方向外側に突出する延出部12が、全長方向の全体に亘り形成されている。この対向する一対の延出部12,12と、左右のサイドフレーム2,2と、閉塞蓋11とには、開口パネル6の開口部分が閉塞蓋11によって閉塞された状態でロックするロック機構13が設けられている。   Incidentally, the opening side horizontal frame 3A is formed with an extending portion 12 protruding outward in the vertical direction with respect to the opening surface of the opening panel 6 over the entire length direction.

このロック機構13は、具体的には、プレート状の複数のロック部材14,16を閉塞蓋11に回動可能に取付け、サイドフレーム2及び延出部12にロック部材14,16が挿脱されるロック孔2b,12aをそれぞれに穿設し、ロック部材14,16毎に該ロック部材14,16を所定の回動位置で固定する固定部材17を設けることにより構成されている。   Specifically, the lock mechanism 13 is configured such that a plurality of plate-like lock members 14 and 16 are rotatably attached to the closing lid 11, and the lock members 14 and 16 are inserted into and removed from the side frame 2 and the extension portion 12. The lock holes 2b and 12a are respectively formed, and a fixing member 17 is provided for each of the lock members 14 and 16 to fix the lock members 14 and 16 at a predetermined rotational position.

さらに詳しく説明すると、合成樹脂製のロック部材14,16は、一対のサイドフレーム2側にそれぞれ1個づつ設けられた端側ロック部材14,14と、一対の端側ロック部材14,14の間に挟まれた中央側ロック部材16との2種類がある。各端側ロック部材14は、近い側のサイドフレーム2及び一対の対向する延出部12にそれぞれ延びるT字状に形成される。中央側ロック部材16は、一対の延出部12に延びる直線状に形成されている。これらのロック部材14,16の形状に対応して、各延出部12には、3つロック孔12aが穿設され、各サイドフレーム2には1つロック2bが穿設されている。   More specifically, the lock members 14 and 16 made of synthetic resin are provided between the end-side lock members 14 and 14 provided one by one on the pair of side frames 2 and between the pair of end-side lock members 14 and 14. There are two types, the central side locking member 16 sandwiched between the two. Each end-side lock member 14 is formed in a T shape extending to the side frame 2 on the near side and the pair of opposing extending portions 12. The center side locking member 16 is formed in a straight line extending to the pair of extending portions 12. Corresponding to the shape of these lock members 14 and 16, each extension portion 12 is provided with three lock holes 12a, and each side frame 2 is provided with one lock 2b.

そして、ロック部材14,16を一方側(ロック側)に回動すると、該ロック部材14の延出部分がそれぞれロック孔12a,12a,2bに、該回動方向から挿入され、さらに、そこから所定回動位置(ロック位置)までロック部材14,16をロック側に回動させると、ロック孔12a,12aの端面に当接するとともに、このようにしてロック位置に回動された端側ロック部材14,16を、他方側(ロック解除側)に回動すると、3つの延出部分がそれぞれロック孔12a,12a,2bから抜出す回動位置(ロック解除位置)まで回動される。   When the lock members 14 and 16 are rotated to one side (lock side), the extended portions of the lock member 14 are inserted into the lock holes 12a, 12a and 2b from the rotation direction, respectively, and from there When the lock members 14 and 16 are rotated to the lock side to a predetermined rotation position (lock position), the end-side lock member is brought into contact with the end surfaces of the lock holes 12a and 12a and thus rotated to the lock position. When 14 and 16 are rotated to the other side (the lock release side), the three extending portions are rotated to the rotation positions (lock release positions) where they are extracted from the lock holes 12a, 12a and 2b, respectively.

そして、合成樹脂製の固定部材17によって、上記ロック位置に位置する各ロック部材14,16を該回動位置で固定すると、閉塞蓋11が、一対の延出部12,12及び一対のサイドフレーム2,2に囲繞されるように嵌め込み固定されることにより、開口パネル6の開口部分が閉塞蓋11によって閉塞された状態でロックされる一方で、固定部材17による固定を解除して各ロック部材14,16を、ロック解除位置まで回動させると、閉塞蓋11を、上記嵌め込み位置から取外し可能なロック解除状態になる。   Then, when the lock members 14 and 16 positioned at the lock position are fixed at the rotation position by the synthetic resin fixing member 17, the closing lid 11 has a pair of extending portions 12 and 12 and a pair of side frames. By being fitted and fixed so as to be surrounded by 2 and 2, the opening portion of the opening panel 6 is locked in a state of being closed by the closing lid 11, while the fixing by the fixing member 17 is released and each locking member is released. When 14 and 16 are rotated to the unlocking position, the closing lid 11 is brought into an unlocked state where it can be removed from the fitting position.

ちなみに、上記構成を実現すべく、延出部12の各ロック孔12a,12aは、挿脱されるロック部材14,16のロック位置から、接線方向ロック解除側に延びるように形成されている。   Incidentally, in order to realize the above-described configuration, the lock holes 12a and 12a of the extending portion 12 are formed so as to extend from the lock position of the lock members 14 and 16 to be inserted / removed to the tangential lock release side.

また、各端側ロック部材14のサイドフレーム2側に延出した部分には、開口パネル6に対して進退する押圧部材18がネジ係合されており、押圧部材18のネジ締めによって、閉塞蓋11が開口パネル6側に押圧されるとともに、ネジ締め解除によって、閉塞蓋11の開口パネル6への押圧が解除される。この一対の押圧部材18,18の押圧によって、閉塞蓋11が、反返り無く、バレルフレーム4の1つの側面側に嵌め込み固定される。   In addition, a pressing member 18 that advances and retreats with respect to the opening panel 6 is screw-engaged with a portion of each end-side lock member 14 that extends toward the side frame 2. 11 is pressed to the opening panel 6 side, and the pressing of the closing lid 11 to the opening panel 6 is released by releasing the screw tightening. By the pressing of the pair of pressing members 18, 18, the closing lid 11 is fitted and fixed to one side surface of the barrel frame 4 without rebounding.

FIG. 6 is a cross-sectional view showing a state in which the peripheral wall panel is fitted in the locking groove of the horizontal frame.

周壁パネル7は、一対のサイドフレーム2,2の一方から他方に至る距離よりも若干長い全長を有するとともに、嵌め込み対象である一対の横フレーム3A,3B(隣合う開口側横フレーム3Aと周壁側横フレーム3B、或いは隣合う周壁側横フレーム3B,3B同士)の間の距離よりも若干広い幅を有する方形板状に成形された合成樹脂製部材である。   The peripheral wall panel 7 has an overall length slightly longer than the distance from one of the pair of side frames 2 and 2 to the other, and a pair of horizontal frames 3A and 3B (an adjacent opening side horizontal frame 3A and the peripheral wall side) This is a synthetic resin member formed into a rectangular plate shape having a width slightly wider than the distance between the horizontal frame 3B or adjacent peripheral wall side horizontal frames 3B, 3B).

周壁パネル7には、全体に亘り複数(具体的には多数)の円状の孔19が形成され、通液性が確保されており、周壁パネル7外面(バレル軸Yから遠い側の面)の幅方向両端部には、全長方向全体に亘り、バレル軸Yと平行な凹部7a,7aが、それぞれ形成されている。この各凹部7aは、断面視半円状に形成されている。   The peripheral wall panel 7 is formed with a plurality of (specifically, many) circular holes 19 throughout to ensure liquid permeability, and the outer surface of the peripheral wall panel 7 (surface far from the barrel axis Y). Concave portions 7a and 7a parallel to the barrel axis Y are formed at both ends in the width direction over the entire length direction. Each of the recesses 7a is formed in a semicircular shape in cross section.

一方、上述の周壁側横フレーム3Bは、方形状の断面を有する四角柱状に成形され、周壁側横フレーム3Bにおける4つの側面の1つは、バレル軸Y側(バレルフレーム4内)に向けられ、且つ該バレル軸Y(バレルフレーム4内の中央部)に向かって盛上った円弧面21によって構成されている。   On the other hand, the above-mentioned peripheral wall side horizontal frame 3B is formed in a quadrangular prism shape having a square cross section, and one of the four side surfaces of the peripheral wall side horizontal frame 3B is directed to the barrel axis Y side (inside the barrel frame 4). And an arcuate surface 21 that rises toward the barrel axis Y (center portion in the barrel frame 4).

また、隣合う開口側横フレーム3Aと周壁側横フレーム3Bにおける互いの対向端面(対向面)には、相互に遠ざかる側に窪んだ断面視方形状の係止溝22,22が、バレル軸Y方向と平行に、全長方向全体に亘り、それぞれ凹設されている。これに加えて、隣合う周壁側横フレーム3B,3B同士における互いの対向端面(対向面)にも、相互に遠ざかる側に窪んだ断面視方形状の係止溝22,22が、バレル軸Y方向と平行に、全長方向全体に亘り、それぞれ凹設されている。   Further, on the opposing end surfaces (opposing surfaces) of the adjacent opening-side horizontal frame 3A and peripheral wall-side horizontal frame 3B, locking grooves 22 and 22 that are recessed in a cross-sectional view are formed on the barrel shaft Y. In parallel with the direction, the entire length direction is recessed. In addition to this, locking grooves 22, 22 that are recessed in the cross-sectional view are also formed on the barrel axis Y on the opposing end surfaces (opposing surfaces) of the adjacent peripheral wall side horizontal frames 3 B, 3 B. In parallel with the direction, the entire length direction is recessed.

上記の各係止溝22は、さらに具体的には、底面と、周壁パネル7外面に近接又は接触する面である外側側面(側面)と、周壁パネル7内面(バレル軸Yに近い側の面)に近接又は接触する面である内側側面(側面)とによって構成されている。この各係止溝22の外側側面には、上述した凹部7aと同一形状を有してバレル軸Yと平行に延びる凹部22aが、係止溝22の全長方向全体に亘り形成されている。   More specifically, each of the locking grooves 22 includes a bottom surface, an outer side surface (side surface) that is close to or in contact with the outer surface of the peripheral wall panel 7, and an inner surface of the peripheral wall panel 7 (surface on the side close to the barrel axis Y). ) And an inner side surface (side surface) which is a surface close to or in contact with. On the outer side surface of each locking groove 22, a recess 22 a having the same shape as the above-described recess 7 a and extending in parallel with the barrel axis Y is formed over the entire length of the locking groove 22.

このような構成によって、隣合う横フレーム3A,3B(開口側横フレーム3Aと周壁側横フレーム3B、或いは、隣合う周壁側横フレーム3A,3A同士)は、係止溝22,22の底面が互いに平行に対向し、該一対の係止溝22,22に、周壁パネル7の幅方向両端部(連結フレーム側両端部)が嵌合挿入されるようにして、該周壁パネル7を、隣合う横フレーム3A,3Bの間に、バレル軸Y方向の沿って、スライド挿入することにより、該隣合う横フレーム3A,3B間に、周壁パネル7を嵌め込む。   With such a configuration, the adjacent horizontal frames 3A and 3B (the opening side horizontal frame 3A and the peripheral wall side horizontal frame 3B or the adjacent peripheral wall side horizontal frames 3A and 3A) have the bottom surfaces of the locking grooves 22 and 22 respectively. Oppositely parallel to each other, the circumferential wall panel 7 is adjacent to the pair of locking grooves 22 and 22 so that both ends in the width direction of the circumferential wall panel 7 (both ends on the connecting frame side) are fitted and inserted. The peripheral wall panel 7 is fitted between the adjacent horizontal frames 3A and 3B by sliding and inserting between the horizontal frames 3A and 3B along the barrel axis Y direction.

この周壁パネル7の横フレーム3A,3B間への嵌め込み時、係止溝22の半円弧面状の凹部22aと、周壁パネル7の半円弧面状の凹部7aとが、断面視で係止溝22外側側面と、周壁パネル7外面との境界を挟んで対称箇所に位置するように、該凹部7a,22aが配置構成され、これによって、この2つの凹部7a,22によって断面視円形の挿入孔(挿入部)23が形成される。この挿入孔23は、前記の構成により、周壁パネル7及び横フレーム3A,3Bの全長方向全体に亘り形成され、この挿入穴23は、円柱状(丸棒上)の合成樹脂製の規制棒24が、嵌合状態で挿入される。   When the peripheral wall panel 7 is fitted between the horizontal frames 3A and 3B, the semicircular arc-shaped concave portion 22a of the locking groove 22 and the semicircular arc-shaped concave portion 7a of the peripheral wall panel 7 are in the cross sectional view. The recesses 7a and 22a are arranged and arranged so as to be located symmetrically across the boundary between the outer side surface of the 22 and the outer surface of the peripheral wall panel 7, whereby the two recesses 7a and 22 have a circular insertion hole in a sectional view. (Insert part) 23 is formed. The insertion hole 23 is formed over the entire length of the peripheral wall panel 7 and the lateral frames 3A and 3B in the above-described configuration. The insertion hole 23 is a cylindrical (on a round bar) regulating rod 24 made of synthetic resin. Is inserted in a fitted state.

このようにして、周壁パネル7と係止溝22の境界に形成された挿入孔23に、規制棒24が嵌合挿入されると、周壁パネル7が、自身の幅方向への移動が規制された状態で、隣合う横フレーム3A,3Bの間に、安定的に嵌め込み固定される。   In this way, when the restriction bar 24 is fitted and inserted into the insertion hole 23 formed at the boundary between the peripheral wall panel 7 and the locking groove 22, the movement of the peripheral wall panel 7 in its width direction is restricted. In this state, it is stably fitted and fixed between the adjacent horizontal frames 3A and 3B.

すなわち、挿入孔23と、規制棒24とは、係止溝22に挿入された周壁パネル7の端部と、該係止溝22との境界をなす互いの接触又は近接面(具体的には、周壁パネル7外面と、係止溝22の外側側面)に設けられ、且つ、この面同士がずれる方向(具体的には、周壁パネル7の幅方向)への周壁パネル7の移動を規制する規制部を構成している。   That is, the insertion hole 23 and the regulation rod 24 are in contact with each other or adjacent surfaces (specifically, the boundary between the end of the peripheral wall panel 7 inserted into the locking groove 22 and the locking groove 22 (specifically, Further, the movement of the peripheral wall panel 7 in a direction (specifically, the width direction of the peripheral wall panel 7) provided on the outer surface of the peripheral wall panel 7 and the outer side surface of the locking groove 22 is shifted. It constitutes the regulation section.

また、この際、横フレーム3A,3Bの全長と、周壁パネル7の長手方向の長さと、規制棒24の全長とは同一又は略同一に設定され、係止溝22も横フレーム3A,3Bの一端から他端に至る長さに設定され、2種類の凹部7a,22aも、周壁パネル7及び係止溝22の全長方向全体に亘り形成されている。このため、周壁パネル7の全長方向両端と、横フレーム3A,3Bの全長方向両端と、規制棒24の全長方向両端とは、全て、揃えられた状態で、バレル1の組立が完了する。   At this time, the total length of the horizontal frames 3A and 3B, the length of the peripheral wall panel 7 in the longitudinal direction, and the total length of the regulating rod 24 are set to be the same or substantially the same, and the locking groove 22 is also formed on the horizontal frames 3A and 3B. The length is set from one end to the other end, and the two types of recesses 7 a and 22 a are also formed over the entire length of the peripheral wall panel 7 and the locking groove 22. For this reason, the assembly of the barrel 1 is completed with the both ends in the full length direction of the peripheral wall panel 7, the both ends in the full length direction of the horizontal frames 3A and 3B, and the both ends in the full length direction of the regulating rod 24 all being aligned.

次に、図5及び7に基づいて、バレル1の組立工程について説明する。
図7(A)はサイドフレームに横フレームを組付ける状態を示す説明図であり、(B)は(A)の要部斜視図である。まず、一方のサイドフレーム2への各横フレーム3A,3Bの組付作業を行う。
Next, the assembly process of the barrel 1 will be described with reference to FIGS.
FIG. 7A is an explanatory view showing a state in which the horizontal frame is assembled to the side frame, and FIG. 7B is a perspective view of the main part of FIG. First, the assembly work of each horizontal frame 3A, 3B to one side frame 2 is performed.

なお、各サイドフレーム2における他方のサイドフレーム2との対向面には、横フレーム3A,3Bの一端側及び周壁パネル7の一端側を嵌合させて位置決めする嵌合溝26が凹設されている。この嵌合溝26はバレル1の断面形状に沿う多角形状に形成される。この多角形の嵌合溝26の各頂点部分には、横フレーム3A,3Bの一端側を嵌合させるフレーム嵌合部26aが形成されるとともに、各辺部分には、開口パネル6及び周壁パネル7の一端側を嵌合させるパネル嵌合部26bが形成されており、この2種類の嵌合部26a,26bは、同一深さに設定されている。   Note that a fitting groove 26 for fitting and positioning one end side of the lateral frames 3A and 3B and one end side of the peripheral wall panel 7 is formed in the surface of each side frame 2 facing the other side frame 2 in a recessed manner. Yes. The fitting groove 26 is formed in a polygonal shape along the cross-sectional shape of the barrel 1. A frame fitting portion 26a for fitting one end side of the horizontal frames 3A and 3B is formed at each apex portion of the polygonal fitting groove 26, and an opening panel 6 and a peripheral wall panel are formed at each side portion. A panel fitting portion 26b for fitting one end side of 7 is formed, and the two types of fitting portions 26a and 26b are set to the same depth.

そして、一方のサイドフレーム2の各フレーム嵌合部26aに、対応する各横フレーム3A、3Bの一端側を嵌合挿入して位置決めした状態で、ボルト27を、嵌合溝26が形成されていない面から該サイドフレーム2に挿通させ、このようにしてサイドフレーム2に挿通された該ボルト27を、横フレーム3A、3Bの上記一端側に形成された軸方向のネジ孔28に挿入してネジ係合させ、締付固定することにより、各横フレーム3A,3Bが、該サイドフレーム2に取付固定される。   The fitting groove 26 is formed with the bolt 27 in a state in which one end side of each corresponding horizontal frame 3A, 3B is fitted and inserted into each frame fitting portion 26a of one side frame 2. The bolt 27 inserted through the side frame 2 in this way is inserted into the axial screw hole 28 formed on the one end side of the horizontal frames 3A and 3B. The horizontal frames 3A and 3B are attached and fixed to the side frames 2 by engaging with screws and tightening and fixing.

続いて、図5に示すように、隣合う開口側横フレーム3A,3A間に、バレル軸Y方向の沿って開口パネル6を、差込み挿入するとともに、隣合う開口側横フレーム3Aと周壁側横フレーム3Bとの間、並びに、隣合う周壁側横フレーム3B,3B同士との間、バレル軸Y方向の沿って周壁パネル7を差込み挿入する。   Subsequently, as shown in FIG. 5, the opening panel 6 is inserted and inserted along the barrel axis Y direction between the adjacent opening side horizontal frames 3A, 3A, and the adjacent opening side horizontal frame 3A and the peripheral wall side horizontal The peripheral wall panel 7 is inserted and inserted along the barrel axis Y direction between the frame 3B and between the adjacent peripheral wall side horizontal frames 3B and 3B.

続いて、この開口パネル6及び各周壁パネル7の一端側が、前記一方のサイドフレーム2の対応する各パネル嵌合部26bに嵌合挿入される位置までスライドさせることにより、隣合う横フレーム3A,3B間に、開口パネル6及び各周壁パネル7が嵌め込まれる。この際、隣接する周壁パネル7,7同士の内面は、横フレーム3Bの円弧面によって、滑らかに連接され、メッキ処理時の作業の質を向上させる。   Subsequently, by sliding the opening panel 6 and one end side of each peripheral wall panel 7 to a position where the one side frame 2 is fitted and inserted into the corresponding panel fitting portion 26b, the adjacent horizontal frames 3A, Between 3B, the opening panel 6 and each surrounding wall panel 7 are engage | inserted. At this time, the inner surfaces of the adjacent peripheral wall panels 7 and 7 are smoothly connected by the circular arc surface of the horizontal frame 3B to improve the quality of work during the plating process.

続いて、係止溝22と周壁パネル7によって形成された各挿入孔23に、規制棒24の全体をぴったりと嵌合挿入し、必要に応じて、通電時の抵抗熱等により規制棒24を溶融させ、樹脂溶接を行うか、或いは、規制棒24全体を挿入穴23に嵌合挿入した直後の状態のまま、次の工程に進む。   Subsequently, the entire restriction rod 24 is fitted and inserted into each insertion hole 23 formed by the locking groove 22 and the peripheral wall panel 7, and the restriction rod 24 is attached by resistance heat or the like when energized as necessary. It melts and performs resin welding, or proceeds to the next step while maintaining the state immediately after the entire restriction rod 24 is fitted and inserted into the insertion hole 23.

続いて、他方サイドフレーム2の嵌合溝26の各フレーム嵌合部26a及びパネル嵌合部26bに、開口パネル6の他端側と、各周壁パネル7の他端側と、各横フレーム3A,3Bの他端側とを、嵌合させ、最後に、前記の場合と同様に、ボルト27及びネジ孔28を利用して、各横フレーム3A,3Bを該他方のサイドフレーム2に取付固定することにより、バレル1及びバレルフレーム4の全体の輪郭が定まり、全体の組付作業が略完了する。ちなみに、必要に応じて、各部材の継ぎ目を、合成樹脂による溶接によって、滑らかに接合させる。   Subsequently, the frame fitting portions 26a and the panel fitting portions 26b of the fitting grooves 26 of the other side frame 2 are connected to the other end side of the opening panel 6, the other end side of each peripheral wall panel 7, and each horizontal frame 3A. , 3B are fitted to each other, and finally, the lateral frames 3A, 3B are attached and fixed to the other side frame 2 using the bolts 27 and the screw holes 28 in the same manner as described above. By doing so, the whole outlines of the barrel 1 and the barrel frame 4 are determined, and the entire assembling work is substantially completed. Incidentally, if necessary, the joints of the respective members are smoothly joined by welding with a synthetic resin.

次に、図8に基づき、本発明の別実施形態について、上述の例と異なる点を説明する。
図8は、本発明の別実施形態を示す要部断面図である。同図に示す通り、周壁パネル7外面に、バレル軸Y方向に対して平行な凹状嵌合部(嵌合部)7bを形成する一方で、係止溝22の外側側面に、バレル軸Y方向に対して平行な凸状嵌合部(嵌合部)22bを形成している。ちなみに、この凸状嵌合部22bは、周壁パネル7の嵌め込み固定時、周壁パネル7の凹状嵌合部7bが位置する箇所に形成されている。
Next, based on FIG. 8, a different point from the above-mentioned example is demonstrated about another embodiment of this invention.
FIG. 8 is a cross-sectional view of a main part showing another embodiment of the present invention. As shown in the figure, a concave fitting part (fitting part) 7b parallel to the barrel axis Y direction is formed on the outer surface of the peripheral wall panel 7, while a barrel axis Y direction is formed on the outer side surface of the locking groove 22. The convex fitting part (fitting part) 22b parallel to is formed. Incidentally, the convex fitting portion 22b is formed at a position where the concave fitting portion 7b of the peripheral wall panel 7 is located when the peripheral wall panel 7 is fitted and fixed.

そして、周壁パネル7の端部を、バレル軸Y方向に沿って、係止溝22にスライド挿入すると、凹状嵌合部7bと凸状嵌合部22bが凹凸嵌合し、周壁パネル7の幅方向への移動が規制されて状態になる。すなわち、周壁パネル7及び係止溝22の嵌合部7a,22bによって、周壁パネル7の幅方向への移動を規制する上述の規制部を構成している。   Then, when the end portion of the peripheral wall panel 7 is slid into the locking groove 22 along the barrel axis Y direction, the concave fitting portion 7b and the convex fitting portion 22b are concavo-convexly fitted, and the width of the peripheral wall panel 7 is reached. Movement in the direction is restricted and the state is reached. That is, the fitting part 7a, 22b of the peripheral wall panel 7 and the locking groove 22 constitutes the above-described restricting part that restricts movement of the peripheral wall panel 7 in the width direction.

なお、この一対の嵌合部7b,22bの凹凸を逆にしてもよい。すなわち、周壁パネル7側の嵌合部7bを凸状に形成し、係止溝22側の嵌合部22bを凹状に形成してもよい。   In addition, you may reverse the unevenness | corrugation of this pair of fitting part 7b, 22b. That is, the fitting portion 7b on the peripheral wall panel 7 side may be formed in a convex shape, and the fitting portion 22b on the locking groove 22 side may be formed in a concave shape.
