The outer arc guide portion is set to be longer than the line connecting the end portion and the fragile portion so that the rotation end of the outer arc guide portion protrudes.

請求項３に係る発明は、下端に係止爪を備えたピン部の上端に脆弱部を介して柄部を設けてなる連結ピンを取り扱う方法であり、柄部を把持して連結ピンを移動し、予め積層した複数の板材の挿入孔へ前記ピン部を挿入し、次に柄部を切除する、一連の作業を行うピン打ち方法であって、柄部を把持する把持部と、挿入孔に挿入した連結ピンにおける脆弱部を中心に描かれる円弧ガイド部を有し、この円弧ガイド部を介して把持部を支える把持部支持部材と、円弧ガイド部に沿って把持部を脆弱部を中心に回動させる把持部回動機構と、この把持部回動機構並びに把持部支持部材を一括して昇降させる昇降機構と、を備えたピン打ち装置の把持部に連結ピンの前記柄部を把持させる柄部把持工程と、予め積層した複数の板材の挿入孔へ前記ピン部を挿入する工程と、挿入孔に挿入した連結ピンにおける脆弱部を中心に柄部を円弧ガイド部に沿って回動させる柄部回動工程と、脆弱部から柄部の略長手軸方向にある所定位置を中心にさらに回動させて脆弱部を剪断破断させる脆弱部破断工程と、を含むことを特徴とする。 The invention according to claim 3 is a method of handling a connecting pin in which a handle portion is provided via a fragile portion at the upper end of a pin portion having a locking claw at the lower end, and the connecting pin is moved by gripping the handle portion. A pinning method for performing a series of operations in which the pin portion is inserted into insertion holes of a plurality of plate members stacked in advance and then the handle portion is excised, a gripping portion for holding the handle portion, and an insertion hole The connecting pin inserted in the guide pin has an arc guide portion drawn around the weakened portion, the gripping portion support member that supports the gripping portion via the arcuate guide portion, and the gripping portion is centered on the weakened portion along the arc guide portion.

請求項１に係る発明では、ピン打ち装置に、把持部と、円弧ガイド部を有し、この円弧ガイド部を介して把持部を支える把持部支持部材と、円弧ガイド部に沿って把持部を脆弱部を中心に回動させる把持部回動機構と、この把持部回動機構並びに把持部支持部材を一括して昇降させる昇降機構とが備えられている。   In the invention according to claim 1, the pinning device includes a gripping portion and an arc guide portion, a gripping portion support member that supports the gripping portion via the arc guide portion, and a gripping portion along the arc guide portion. A gripping portion rotating mechanism that rotates around the fragile portion, and an elevating mechanism that moves the gripping portion rotating mechanism and the gripping portion support member up and down collectively are provided.

すなわち、ピン打ち装置は、連結ピンの柄部を把持して移動し、予め積層した複数の板材の挿入孔へピン部を挿入し、次に柄部を切除することができる装置としたので、作業者をピン打ち作業に介在させることなく、ピン打ち作業の自動化を図ることができる。
ピン打ち作業を自動化したので、ピン打ち作業の作業時間が一定となり、生産性を大幅に高めることが可能となる。 That is, since the pinning device is a device that can grip and move the handle portion of the connecting pin, insert the pin portion into the insertion holes of a plurality of previously laminated plate materials, and then cut the handle portion. It is possible to automate the pinning work without interposing an operator in the pinning work.
Since the pinning work is automated, the work time of the pinning work is constant, and the productivity can be greatly increased.

脆弱部でうまく切断できるか否かは、柄部の回動速度が重要な因子となる。すなわち、ゆっくりと柄部を回動させると、脆弱部で樹脂が伸びてしまい、切断できなくなる。一方、素早く柄部を回動させると、伸びる前に切断が完了する。
本発明では、柄部の回動を自動化したので、回動速度を高めることができ、生産性を向上させることができる。 Whether or not the fragile part can cut well is an important factor of the rotation speed of the handle part. That is, if the handle portion is slowly rotated, the resin extends at the fragile portion and cannot be cut. On the other hand, if the handle is quickly rotated, the cutting is completed before extending.
In the present invention, since the rotation of the handle portion is automated, the rotation speed can be increased and the productivity can be improved.

請求項２に係る発明では、円弧ガイド部には、外側円弧ガイド部と、この外側円弧ガイド部よりも脆弱部に近づけて設けられる内側円弧ガイド部とを含み、この内側円弧ガイド部の回動終端と脆弱部とを結ぶ線よりも、外側円弧ガイド部の回動終端がはみ出すように、外側円弧ガイド部を長く設定したので、把持部が内側円弧ガイド部の回動終端に達した後、この回動終端を中心に回動させることができる。把持部の回動中心が内側円弧ガイド部の回動終端になることで、連結ピンの脆弱部には曲げ力に加え剪断力がかかるので、柄部をピン部から確実に切除することができる。   In the invention according to claim 2, the arc guide portion includes an outer arc guide portion and an inner arc guide portion provided closer to the fragile portion than the outer arc guide portion, and the inner arc guide portion rotates. Since the outer arc guide portion is set to be longer than the line connecting the end portion and the fragile portion so that the rotation end of the outer arc guide portion protrudes, after the gripping portion reaches the rotation end of the inner arc guide portion, It can be rotated around this rotation end. Since the center of rotation of the gripping part is the end of rotation of the inner circular arc guide part, the brittle part of the connecting pin is subjected to shearing force in addition to bending force, so that the handle part can be surely cut off from the pin part. .

請求項３に係る発明では、柄部を切除する工程は、脆弱部を中心に柄部を回動させる柄部回動工程と、脆弱部から柄部の略長手軸方向にある所定位置を中心にさらに回動させて脆弱部を剪断破断させる脆弱部破断工程との２工程からなるので、柄部をピン部から分離することができる。柄部をピン部から分離することによって、柄部をピン部から確実に切除することができる。   In the invention according to claim 3, the step of cutting the handle portion includes a handle portion rotating step of rotating the handle portion around the weak portion, and a predetermined position in the substantially longitudinal axis direction of the handle portion from the weak portion. Further, the handle portion is separated from the pin portion by two steps including a weak portion breaking step in which the weak portion is sheared and broken. By separating the handle portion from the pin portion, the handle portion can be surely excised from the pin portion.

And consist of

第３円弧ガイド部１６７及び第３ガイド軸１２９は、原理上は不要であるが、把持部５１の回動を円滑にするために設けられたものである。
すなわち、円弧ガイド部１６０には、第２円弧ガイド部１６６としての外側円弧ガイド部１６９と、この外側円弧ガイド部１６９よりも脆弱部４２に近づけて設けられる第１円弧ガイド部１６１としての内側円弧ガイド部１６８とを含み、この内側円弧ガイド部１６８の回動終端１６３と脆弱部４２とを結ぶ線１７４よりも、外側円弧ガイド部１６９の回動終端１６４がはみ出すように、外側円弧ガイド部１６９は長く設定されている。 The third arc guide portion 167 and the third guide shaft 129 are not necessary in principle, but are provided in order to smoothly rotate the grip portion 51.
That is, the arc guide portion 160 has an outer arc guide portion 169 as the second arc guide portion 166 and an inner arc as the first arc guide portion 161 provided closer to the fragile portion 42 than the outer arc guide portion 169. The outer arc guide portion 169 includes a guide portion 168 so that the rotation end 164 of the outer arc guide portion 169 protrudes beyond a line 174 connecting the rotation end 163 of the inner arc guide portion 168 and the fragile portion 42.

You may make it the structure to which a recessed part material moves.

図６において、保持軸１３５と第２ガイド軸１２８と前記保持軸１３５と前記第２ガイド軸１２８間に掛け渡されるばね部材１３６とは、回動手段６３の右方に設けられているが、回動手段６３の左方に加えて設けることは差し支えない。このように左右両側から把持部本体１２５を支持することにより、把持部本体１２５をより安定的に回動させることができる。   In FIG. 6, the holding shaft 135, the second guide shaft 128, and the spring member 136 spanned between the holding shaft 135 and the second guide shaft 128 are provided on the right side of the rotating means 63. It may be provided in addition to the left side of the rotating means 63. Thus, by supporting the grip part main body 125 from both the left and right sides, the grip part main body 125 can be rotated more stably.

図２に戻って、連結ピン把持部５１の詳細な構造を説明する。
連結ピン把持部５１に、把持部本体１２５の下端部に配置され連結ピン１６の柄部４３の外周面に嵌合する嵌合部１７１と、この嵌合部１７１と連通し嵌合部１７１から圧縮空気を供給又は排出する口である空気口１７２とが備えられている。そして、制御手段（図３の符号９１）の指令により、前述の把持制御用電磁弁（図３の符号７５）が作動し、圧縮エアの流れを変化させることにより、連結ピン１６の柄部４３を吸着又は排出する。 Returning to FIG. 2, the detailed structure of the connecting pin grip 51 will be described.

以上に述べたピン打ち装置の作用を次に述べる。
図７は柄部把持工程から柄部回動工程までの説明図である。
（ａ）において、把持部５１を図示せぬ連結ピンストッカに移動させ、連結ピン１６を吸着して把持するとともに、移動機構（図３の符号５５）により、連結ピン１６が把持されている把持部５１を水平及び上下に移動させ、挿入孔３４の上方の所定位置で停止させる。すなわち、柄部４３を把持して連結ピン１６を所定の位置に移動させる柄部把持工程を示す。 The operation of the pinning device described above will be described next.
FIG. 7 is an explanatory diagram from the handle gripping process to the handle rotating process.
In (a), the gripper 51 is moved to a connection pin stocker (not shown), and the connection pin 16 is attracted and gripped, and the gripping part in which the connection pin 16 is gripped by the moving mechanism (reference numeral 55 in FIG. 3). 51 is moved horizontally and vertically and stopped at a predetermined position above the insertion hole 34. That is, a handle portion gripping process in which the handle portion 43 is gripped and the connecting pin 16 is moved to a predetermined position is shown.

（ｂ）において、昇降機構（図４の符号５７）によって把持部５１を下降させ、連結ピン１６を板材１２としてのセパレータ１３、１４の挿入孔３４に打ち込む連結ピン挿入工程を示す。
このとき、板材１２の上面は、板材押さえ部（図６の符号１４９）によって押圧されている。 4B shows a connecting pin insertion step in which the gripping portion 51 is lowered by an elevating mechanism (reference numeral 57 in FIG. 4), and the connecting pin 16 is driven into the insertion holes 34 of the separators 13 and 14 as the plate material 12. FIG.
At this time, the upper surface of the plate material 12 is pressed by the plate material pressing portion (reference numeral 149 in FIG. 6).

（ｃ）において、把持部５１を連結ピン１６の脆弱部４２を中心に回動させるとともに、回動機構５８によって第１ガイド軸１２７を第１円弧ガイド部１６１の回動終端１６３まで移動させ、柄部４３を脆弱部４２で切除する柄部回動工程を示す。このとき、板材１２の表面は、板材押さえ部（図６の符号１４９）によって押圧されている。   In (c), the grip 51 is rotated around the fragile portion 42 of the connecting pin 16, and the first guide shaft 127 is moved to the rotation end 163 of the first arc guide 161 by the rotation mechanism 58. The handle part rotation process which cuts the handle part 43 in the weak part 42 is shown. At this time, the surface of the plate material 12 is pressed by a plate material pressing portion (reference numeral 149 in FIG. 6).

図８は脆弱部破断工程から把持部退避工程までの説明図である。
（ａ）において、把持部５１を、第１ガイド軸１２７を中心に回動させるとともに、第２ガイド軸１２８を第２円弧ガイド部１６６の回動終端１６４まで移動させ、柄部４３を切除する脆弱部破断工程を示す。このとき、板材１２の表面は、板材押さえ部（図６の符号１４９）によって押圧されている。 FIG. 8 is an explanatory diagram from the fragile portion breaking step to the gripping portion retracting step.
In (a), the grip portion 51 is rotated about the first guide shaft 127 and the second guide shaft 128 is moved to the rotation end 164 of the second arc guide portion 166 to cut the handle portion 43. The weak part fracture process is shown. At this time, the surface of the plate material 12 is pressed by a plate material pressing portion (reference numeral 149 in FIG. 6).

すなわち、柄部４３を切除する工程は、挿入孔３４に挿入した連結ピン１６における脆弱部４２を中心に柄部４３を回動させる柄部回動工程と、脆弱部４２から柄部４３の略長手軸４３Ｊ方向にある所定位置としての第１ガイド軸１２７を中心にさらに回動させて脆弱部４２を剪断破断させる脆弱部破断工程との２工程からなる。   That is, the step of excising the handle portion 43 includes a handle portion rotating step of rotating the handle portion 43 around the weakened portion 42 of the connecting pin 16 inserted into the insertion hole 34, and an abbreviation of the handle portion 43 from the weakened portion 42. It consists of two steps including a weak portion breaking step in which the weak portion 42 is sheared and broken by further rotating around the first guide shaft 127 as a predetermined position in the direction of the longitudinal axis 43J.

図５に戻って、円弧ガイド部１６０には、外側円弧ガイド部１６９と、この外側円弧ガイド部１６９よりも脆弱部４２に近づけて設けられる内側円弧ガイド部１６８とを含み、この内側円弧ガイド部１６８の回動終端１６３と脆弱部４２とを結ぶ線よりも、外側円弧ガイド部１６９の回動終端１６４がはみ出すように、外側円弧ガイド部１６９を長く設定したので、把持部５１が内側円弧ガイド部１６８の回動終端１６３に達した後、この回動終端１６３を中心に回動させることができる。把持部５１の回動中心が内側円弧ガイド部１６８の回動終端１６３になることで、脆弱部４２には曲げ力に加え剪断力がかかるので、柄部４３をピン部４１から短時間で且つ確実に切除することができる。   Returning to FIG. 5, the arc guide portion 160 includes an outer arc guide portion 169 and an inner arc guide portion 168 provided closer to the fragile portion 42 than the outer arc guide portion 169. Since the outer arc guide portion 169 is set so that the rotation end 164 of the outer arc guide portion 169 protrudes beyond the line connecting the rotation end 163 and the fragile portion 42 of 168, the gripping portion 51 becomes the inner arc guide. After reaching the turning end 163 of the part 168, the turning end 163 can be turned around. Since the rotation center of the gripping part 51 is the rotation end 163 of the inner arc guide part 168, the fragile part 42 is subjected to a shearing force in addition to the bending force. Can be excised reliably.

図８（ｂ）において、第２ガイド軸１２８をその回動開始点まで戻すとともに第１ガイド軸１２７をその回動開始点１６２まで戻すという把持部復帰工程を示す。このとき、板材１２の上面は、板材押さえ部（図６の符号１４９）によって押圧されている。   FIG. 8B shows a gripping part returning process in which the second guide shaft 128 is returned to its rotation start point and the first guide shaft 127 is returned to its rotation start point 162. At this time, the upper surface of the plate material 12 is pressed by the plate material pressing portion (reference numeral 149 in FIG. 6).

（ｃ）において、昇降機構５７を上昇させ、把持部５１を退避させるという把持部退避工程を示す。このとき、板材押さえ部（図６の符号１４９）による板材１２の上面の押圧は解除される。
そして、把持されている柄部４３を把持部５１から排出することで、連結ピン打ち込みの１サイクルが終了する。 (C) shows a gripping part retreating process in which the elevating mechanism 57 is raised and the gripping part 51 is retracted. At this time, the pressing of the upper surface of the plate material 12 by the plate material pressing portion (reference numeral 149 in FIG. 6) is released.
Then, by discharging the gripped handle 43 from the gripper 51, one cycle of driving the connecting pin is completed.

ピン打ち装置５０は、連結ピン１６の柄部４３を把持して移動し、予め積層した複数の板材の挿入孔３４へピン部４１を挿入し、次に柄部４３を切除する、一連の作業を行うことができる装置としたので、作業者をピン打ち作業に介在させることなく、ピン打ち作業の自動化を図ることができる。
ピン打ち作業を自動化したので、ピン打ち作業の作業時間が一定となり、生産性を大幅に高めることが可能となる。 The pinning device 50 moves by gripping the handle portion 43 of the connecting pin 16, inserts the pin portion 41 into the insertion holes 34 of a plurality of plate members stacked in advance, and then cuts the handle portion 43. Therefore, the pinning operation can be automated without interposing an operator in the pinning operation.
Since the pinning work is automated, the work time of the pinning work is constant, and the productivity can be greatly increased.

脆弱部でうまく切断できるか否かは、柄部の回動速度が重要な因子となる。すなわち、ゆっくりと柄部を回動させると、脆弱部で樹脂が伸びてしまい、切断できなくなる。一方、素早く柄部を回動させると、伸びる前に切断が完了する。
本発明では、柄部４３の回動を自動化したので、回動速度を高めることができ、生産性を向上させることができる。 Whether or not the fragile portion can be cut well is an important factor of the rotation speed of the handle portion. That is, if the handle portion is slowly rotated, the resin extends at the fragile portion and cannot be cut. On the other hand, if the handle is quickly rotated, the cutting is completed before extending.
In the present invention, since the rotation of the handle portion 43 is automated, the rotation speed can be increased and the productivity can be improved.
