Description

本発明は、プレス装置及びプレス機構付金型に関し、詳しくは小さな駆動力で大きな加圧力が発生できるプレス装置等に関し、例えばプリント基板の分割用として、ハンドプレス或いは小型サーボモータ駆動プレスの形式で実施して好適なプレス装置等に関する。   The present invention relates to a press device and a die with a press mechanism, and more particularly to a press device that can generate a large pressure with a small driving force. For example, in the form of a hand press or a small servo motor driven press for dividing a printed circuit board. The present invention relates to a press apparatus and the like suitable for implementation.

プレス装置は種々の用途に使用されている。例えばプリント基板を使用した電子回路の製造過程では、部品実装部分が複数個設けられたプリント基板の周囲に枠が設けられており、この枠が付いた状態で各部品実装部分に電子部品が実装され、その後、夫々の部品実装部分の間、及びこれらと枠との間がプレス装置で分割され、夫々の部品実装部分が取り出される。
このような用途に使用するプレス装置の形式としては、下記特許文献１，２記載の形式のほか、種々の形式が考えられる。
特開平１０−１７５０９６号公報 特開平０８−１５５６９９号公報 The press apparatus is used for various purposes. For example, in the manufacturing process of an electronic circuit using a printed circuit board, a frame is provided around the printed circuit board on which a plurality of component mounting parts are provided, and an electronic component is mounted on each component mounting part with this frame attached. After that, between each component mounting portion and between these and the frame is divided by a press device, and each component mounting portion is taken out.
In addition to the formats described in Patent Documents 1 and 2 listed below, various formats are conceivable as the format of the press device used for such applications.
JP-A-10-175096 Japanese Patent Application Laid-Open No. 08-155699

しかし、プリント基板の分割用として、例えば３００ｍｍ×１２５ｍｍの金型をセット可能なプレス装置を実現しようとする場合、１トン〜３トン程度の加圧力が発生可能であることが好ましいとされるのであるが、上記特許文献１，２記載のプレス装置を始めとする従来のプレス装置では、このための構造が複雑にならざるを得ず、簡単で安価なプレス装置は実現出来なかった。
本発明の目的は、上記従来のプレス装置の欠点を解消し、大きな加圧力が発生できる一方で、構造が簡単で、安価であるプレス装置等を提供することにある。 However, it is preferable that a pressurizing force of about 1 to 3 tons can be generated when a press apparatus capable of setting a 300 mm × 125 mm mold is used for dividing a printed circuit board. However, in the conventional press apparatuses including the press apparatus described in Patent Documents 1 and 2, the structure for this must be complicated, and a simple and inexpensive press apparatus cannot be realized.
An object of the present invention is to provide a pressing device or the like that eliminates the above-described drawbacks of the conventional pressing device and can generate a large pressure while having a simple structure and being inexpensive.

上記目的達成のため請求項１記載のプレス装置では、主軸の回動で第一の所定距離だけ加圧板を移動させる第一のカムと、主軸の回動で第二の所定距離だけ加圧板を移動させる第二のカムとを備え、該第二のカムの中心から作動完了位置迄の半径は、前記第一のカムの中心から作動完了位置迄の半径より小さくされている。   To achieve the above object, in the press apparatus according to claim 1, the first cam for moving the pressure plate by a first predetermined distance by rotation of the main shaft and the pressure plate by a second predetermined distance by rotation of the main shaft. And a radius from the center of the second cam to the operation completion position is smaller than a radius from the center of the first cam to the operation completion position.

また、請求項２記載のプレス装置では、請求項１記載の第二のカムが複数個備えられている。   Moreover, in the press apparatus of Claim 2, the 2nd cam of Claim 1 is provided with two or more.

また、請求項３のプレス装置では、プリント基板から部品実装部分を打抜くための金型が備えられ、該金型がサーボモータ出力で駆動される。   According to a third aspect of the present invention, there is provided a die for punching out a component mounting portion from a printed circuit board, and the die is driven by a servo motor output.

また、請求項４のプレス機構付金型では、金型と、該金型を加圧するプレス機構とが、一つのフレームに組込まれ一体とされている。   In the mold with a press mechanism according to a fourth aspect, the mold and the press mechanism for pressurizing the mold are integrated in one frame.

請求項１記載のプレス装置では、カムを第一と第二の二段構えとし、該第二のカムの中心から作動完了位置Ｐ２（図８（Ｂ））迄の半径Ｒ２（同）を、前記第一のカムの中心から作動完了位置Ｐ１（図８（Ａ））迄の半径Ｒ１（同）より小さくしている。カムの半径Ｒ２，Ｒ１等は、挺子に見立てると、作用点側の腕の長さとなるが、本発明の如き構造とすれば、従来のカム１個による加圧板押下の場合に比べ、第二のカムの挺子の腕Ｒ２を短くできる。従って、主軸に加えられるトルクが同じだったとしても、従来のものより大きな加圧力が発生出来る。   In the press device according to claim 1, the cam has a first and second two-stage structure, and a radius R2 (same) from the center of the second cam to the operation completion position P2 (FIG. 8B), It is smaller than the radius R1 (same) from the center of the first cam to the operation completion position P1 (FIG. 8A). The cam radii R2, R1 and the like are the length of the arm on the action point side when viewed as an insulator, but with the structure of the present invention, compared to the case of pressing the pressure plate with one conventional cam, The lever arm R2 of the second cam can be shortened. Therefore, even if the torque applied to the main shaft is the same, it is possible to generate a larger pressing force than the conventional one.

また、請求項２記載のプレス装置では、請求項１記載の第二のカムが複数個備えられている。これにより、加圧板が均等に押下され、上型全体に加圧力が掛かる。従って、例えば基板分割等、種々のプレス作業が円滑に実行される。   Moreover, in the press apparatus of Claim 2, the 2nd cam of Claim 1 is provided with two or more. As a result, the pressure plate is pressed evenly, and pressure is applied to the entire upper mold. Accordingly, various pressing operations such as substrate division are smoothly performed.

具体的に、ハンドプレスとして実施するときは、従来のものの２〜３倍、小型サーボモータ駆動として実施するときは、例えば２００ワットのモータで１トン、７００ワットのモータで３トンというように、大きな加圧力を発生できる。２００ワット、７００ワットというような電力は、身近な単相１００ボルト商用電源から容易に得られる。従って、この装置の導入に当っても、例えば２００Ｖ商用電源、油圧源等の駆動源を新たに導入する必要がなく、導入の手間、費用も安く済む。更にカムは構造簡単なものであり、製作容易である。これにより、装置を安価に製作できる。   Specifically, when implemented as a hand press, 2 to 3 times the conventional one, when implemented as a small servo motor drive, for example, 1 ton with a 200 watt motor, 3 ton with a 700 watt motor, A large pressure can be generated. Power such as 200 watts and 700 watts can be easily obtained from a familiar single phase 100 volt commercial power source. Therefore, even when this apparatus is introduced, it is not necessary to newly introduce a driving source such as a 200 V commercial power source or a hydraulic power source, and the labor and cost of introduction can be reduced. Furthermore, the cam has a simple structure and is easy to manufacture. Thereby, an apparatus can be manufactured at low cost.

また、請求項３のプレス装置は、プリント基板から部品実装部分を打抜くための金型を備え、該金型がサーボモータ出力で駆動される。従来、プリント基板からの部品実装部分の打抜きは、油圧や空気圧のプレス装置で行なわれていた。これらのプレス装置では瞬間的な加圧力の制御は難しい。このため、部品実装部分がプリント基板から切り離された瞬間に、いわば力があり余ってしまい、当該部品実装部分に衝撃が加わる。これにより、部品や配線の剥離、部品の破損、基板の亀裂等が生じていた。
サーボモータは、出力を自在に制御できる。それ故、部品実装部分がプリント基板から切り離される瞬間に合わせて出力を下げるなど、部品実装部分に衝撃を与えないように金型を駆動できる。これにより、打抜かれた部品実装部分に部品の剥離等が生ずるのを防止出来る。 According to a third aspect of the present invention, there is provided a press apparatus comprising a mold for punching out a component mounting portion from a printed circuit board, and the mold is driven by a servo motor output. Conventionally, punching of a component mounting portion from a printed circuit board has been performed with a hydraulic or pneumatic press. In these press devices, it is difficult to control the instantaneous pressurizing force. For this reason, at the moment when the component mounting portion is separated from the printed circuit board, there is a surplus force, and an impact is applied to the component mounting portion. As a result, peeling of parts and wiring, damage to parts, cracks in the substrate, and the like occurred.
The servo motor can freely control the output. Therefore, the mold can be driven so as not to give an impact to the component mounting portion, for example, the output is lowered at the moment when the component mounting portion is separated from the printed board. Thereby, it is possible to prevent the parts from being peeled off from the punched component mounting portion.

また、請求項４のプレス機構付金型では、金型と、該金型を加圧するプレス機構とを、一つのフレームに組込んで一体とした。従来、プレス装置と金型とは別体であった。このため、作業内容を変えるたび金型を交換する必要があり、その際の上下の金型の位置合せが煩雑で、両者を精度良く装着するのは難しかった。
請求項４のプレス機構付金型では、両者が一体である。それ故、金型の精度を極めて良好に保つことができる。これにより、金型の取付不良から生ずる製品の不良、金型の破損等が防止される。精度を出すための煩雑な作業も不要になる。 According to a fourth aspect of the present invention, the mold and the press mechanism that pressurizes the mold are integrated into one frame. Conventionally, the press device and the mold are separate bodies. For this reason, it is necessary to exchange the dies each time the work contents are changed, and the alignment of the upper and lower dies at that time is complicated, and it is difficult to mount them with high accuracy.
In the die with a press mechanism according to the fourth aspect, the two are integrated. Therefore, the accuracy of the mold can be kept extremely good. As a result, defective products caused by defective mounting of the mold, damage to the mold, and the like are prevented. No complicated work is required to increase accuracy.

以下、本発明の詳細を図示実施の形態例に基いて説明する。図１は実施の形態例のプレス装置１の正面を示す。図２は、図１のＡ１−Ａ２線で切断したプレス装置１の断面を示す。この図１、図２では、主軸２が待機角度（作動前の角度）にあり、加圧板３が待機位置（作動前の位置）にある。上型４は下型６から１７ｍｍ離間している。   The details of the present invention will be described below based on the embodiments shown in the drawings. FIG. 1 shows the front of a press apparatus 1 according to an embodiment. FIG. 2 shows a cross section of the pressing apparatus 1 cut along the line A1-A2 of FIG. In FIGS. 1 and 2, the main shaft 2 is at a standby angle (angle before operation), and the pressure plate 3 is at a standby position (position before operation). The upper mold 4 is separated from the lower mold 6 by 17 mm.

図３もプレス装置１の正面を示す。図４は、図３のＡ１−Ａ２線で切断したプレス装置１の断面を示す。この図３、図４では、主軸２が６６度回動された所定角度にある（回動方向は図４で見て反時計方向。以下同様。）。このとき加圧板３は待機位置から１７ｍｍ下降した所定位置にあり、待機位置からこの所定位置迄の１７ｍｍが請求項にいう第一の所定距離に当る。また、上型４は下型６内のプリント基板（不図示）に接した状態にある。   FIG. 3 also shows the front of the press device 1. FIG. 4 shows a cross section of the pressing device 1 cut along the line A1-A2 of FIG. 3 and 4, the main shaft 2 is at a predetermined angle rotated 66 degrees (the rotation direction is counterclockwise as viewed in FIG. 4, and so on). At this time, the pressure plate 3 is at a predetermined position lowered by 17 mm from the standby position, and 17 mm from the standby position to this predetermined position corresponds to the first predetermined distance in the claims. The upper mold 4 is in contact with a printed circuit board (not shown) in the lower mold 6.

図５もプレス装置１の正面を示す。図６は、図５のＡ１−Ａ２線で切断したプレス装置１の断面を示す。この図５、図６では、主軸２が１１２度回動された作動完了角度にある。このとき加圧板３は待機位置から２０ｍｍ下降した作動完了位置にあり、前述の所定位置からこの作動完了位置迄の３ｍｍが請求項にいう第二の所定距離に当る。また、上型４は下型６と３ｍｍ噛み合っている。   FIG. 5 also shows the front of the press device 1. FIG. 6 shows a cross section of the press apparatus 1 cut along the line A1-A2 of FIG. 5 and 6, the main shaft 2 is at an operation completion angle rotated 112 degrees. At this time, the pressure plate 3 is in the operation completion position lowered by 20 mm from the standby position, and 3 mm from the predetermined position to the operation completion position corresponds to the second predetermined distance in the claims. Further, the upper mold 4 meshes with the lower mold 6 by 3 mm.

図７、図８は、カム周辺を拡大して示す。これらの図は、図２等と同様に、図１等のＡ１−Ａ２線で切断した断面で示す。なお、ハッチングは省略する。このうち、図７（Ａ）は主軸２が待機角度にある状態を示す（図２と同じ状態）。図７（Ｂ）は主軸２が６６度回動され、所定角度にある状態を示す（図４と同じ状態）。図８（Ａ）は主軸２が９０度回動された状態を示す。図８（Ｂ）は主軸２が１１２度回動され、作動完了角度にある状態を示す（図６と同じ状態）。   7 and 8 show an enlarged view of the periphery of the cam. These figures are shown in a cross section taken along line A1-A2 in FIG. Note that hatching is omitted. Among these, FIG. 7A shows a state in which the main shaft 2 is at the standby angle (the same state as FIG. 2). FIG. 7B shows a state where the main shaft 2 is rotated 66 degrees and is at a predetermined angle (the same state as FIG. 4). FIG. 8A shows a state where the main shaft 2 is rotated 90 degrees. FIG. 8B shows a state in which the main shaft 2 is rotated 112 degrees and is at an operation completion angle (the same state as FIG. 6).

これら各図に於て、７は台板で、下型６はこの台板７の上に摺動自在に配置されている。８は支柱で、台板７の四隅に夫々立設されている。９は天板で、その四隅が４本の支柱８の上端に固定されている。加圧板３には四隅に孔が穿設されており、ここに支柱８が貫通され、加圧板３は上下動自在とされている。１１はこの加圧板３を上方に付勢するスプリングである。加圧板３の下面には、上型４が取着されている。なお、上型４は勿論加圧板３と一緒に動く。加圧板３の上に載置された摺動板１２も加圧板３と一緒に動く。従って、以後は、これらの動きを加圧板３の動きで説明する。   In these drawings, reference numeral 7 denotes a base plate, and the lower die 6 is slidably disposed on the base plate 7. Reference numerals 8 denote support columns, which are respectively erected at the four corners of the base plate 7. Reference numeral 9 denotes a top plate, and the four corners thereof are fixed to the upper ends of the four columns 8. The pressure plate 3 has holes formed at four corners, through which struts 8 pass, and the pressure plate 3 can be moved up and down. A spring 11 biases the pressure plate 3 upward. An upper mold 4 is attached to the lower surface of the pressure plate 3. Of course, the upper mold 4 moves together with the pressure plate 3. The sliding plate 12 placed on the pressure plate 3 also moves together with the pressure plate 3. Therefore, hereinafter, these movements will be described by the movement of the pressure plate 3.

１３は軸受で、天板９の下面に３個設けられており、不図示スプリングで、天板９に向かって付勢され、主軸２を下方に移動可能に支承している。第一のカム１４は、主軸２に２個突設されている。第一のカム１４の反対側には第二のカム１６が各１個づつ突設されている。この第二のカム１６の中心から作動完了位置Ｐ２（図８（Ｂ））迄の半径Ｒ２（同）は、第一のカム１４の中心から作動完了位置Ｐ１（図８（Ａ））迄の半径Ｒ１（同）より小さくされている。カムの半径Ｒ２，Ｒ１等は、挺子に見立てると、作用点側の腕の長さとなるが、この実施の形態例の如き構造とすれば、従来のカム１個による加圧板押下の場合に比べ、第二のカム１６の挺子の腕Ｒ２を短くできる。従って、主軸２に加えらるトルクが同じだったとしても、従来のものより大きな加圧力が発生出来る。なお、摺動板１２は、加圧板３を介してスプリング１１に付勢されている。これにより摺動板１２は第一のカム１４に常時当接している。   Three bearings 13 are provided on the lower surface of the top plate 9 and are urged toward the top plate 9 by a spring (not shown) to support the main shaft 2 so as to be movable downward. Two first cams 14 project from the main shaft 2. On the opposite side of the first cam 14, a second cam 16 is projected one by one. The radius R2 (same) from the center of the second cam 16 to the operation completion position P2 (FIG. 8B) is from the center of the first cam 14 to the operation completion position P1 (FIG. 8A). It is smaller than the radius R1 (same as above). The cam radii R2, R1 and the like are the length of the arm on the action point side when viewed as an insulator, but with the structure as in this embodiment, when the pressure plate is pressed by one conventional cam, In comparison, the lever arm R2 of the second cam 16 can be shortened. Therefore, even if the torque applied to the main shaft 2 is the same, it is possible to generate a larger pressing force than the conventional one. The sliding plate 12 is biased by the spring 11 via the pressure plate 3. Thereby, the sliding plate 12 is always in contact with the first cam 14.

主軸２の回動であるが、先ず、ハンドプレスとして実施する場合は、主軸２の右端近く（図１矢印Ｂで示す位置）にハンドルを取着し、これを人の手で回動する。また、サーボモータ駆動プレスとして実施する場合は、天板９の上にサーボモータを載置し、このモータの出力軸及び主軸２にプーリを取着し、これらにベルトを張架して主軸２を回動する。   The main shaft 2 is rotated. First, when it is implemented as a hand press, a handle is attached near the right end of the main shaft 2 (position indicated by arrow B in FIG. 1), and this is rotated by a human hand. When the servo motor drive press is implemented, a servo motor is mounted on the top plate 9, pulleys are attached to the output shaft and the main shaft 2 of the motor, and a belt is stretched over them to support the main shaft 2. Rotate.

一般的なハンドプレスでは、主軸２の回転角度は１１０度位とされている。そこで、この実施の形態例でも、主軸２の回動角を１１２度としている。また、プリント基板の分割に使用する場合、上型４の待機位置（図１、図７（Ａ））から作動完了位置（図５、図８（Ｂ））までの距離、即ち上型４の行程は２０ｍｍ程度必要とされている。そこで、この実施の形態例でも、この上型４の行程、言い換えれば加圧板３の行程を２０ｍｍとしている。   In a general hand press, the rotation angle of the main shaft 2 is about 110 degrees. Therefore, also in this embodiment, the rotation angle of the main shaft 2 is 112 degrees. When used for dividing the printed circuit board, the distance from the standby position of the upper mold 4 (FIGS. 1 and 7A) to the operation completion position (FIGS. 5 and 8B), that is, the upper mold 4 The stroke is required about 20 mm. Therefore, also in this embodiment, the stroke of the upper mold 4, in other words, the stroke of the pressure plate 3 is set to 20 mm.

この行程２０ｍｍのうち、加圧力が必要とされるのは、上型４の行程の最後の方、即ち、上型４がプリント基板を下型６に押圧し、プリント基板を分割していくときの２ｍｍ位の範囲である。そこで、本実施の形態例では、これより１ｍｍ多い最後の３ｍｍの分を、大きな加圧力が発生される範囲とし、この範囲を、前記半径Ｒ２が小さい第二のカム１６で駆動する。このときの主軸２の回動角としては、前記１１２度のうちの後半４６度を割当て、この４６度の回動で加圧板３を３ｍｍ下降させる。また、ここに至るまでの１７ｍｍの範囲を、加圧板３を下降させて行く範囲とし、第一のカム１４で駆動する。このときの主軸２の回動角としては、前記１１２度のうちの前半６６度を割当て、この６６度の回動で加圧板３を１７ｍｍ下降させる。   Of this stroke 20 mm, the pressure is required at the end of the stroke of the upper die 4, that is, when the upper die 4 presses the printed board against the lower die 6 and divides the printed board. Of about 2 mm. Therefore, in this embodiment, the last 3 mm, which is 1 mm larger than this, is set as a range in which a large pressing force is generated, and this range is driven by the second cam 16 having a small radius R2. The rotation angle of the main shaft 2 at this time is assigned 46 degrees in the latter half of the 112 degrees, and the pressure plate 3 is lowered by 3 mm by the rotation of 46 degrees. Further, the range of 17 mm up to this point is the range in which the pressure plate 3 is lowered, and the first cam 14 is used for driving. As the rotation angle of the main shaft 2 at this time, the first half 66 degrees of the 112 degrees is assigned, and the pressure plate 3 is lowered by 17 mm by the rotation of the 66 degrees.

実施の形態例のプレス装置１の使用方法は従来のものと変らない。即ち、先ず加圧板３が待機位置にある状態で（図１及び図２、図７（Ａ））、下型６を手前に引き出し、加工対象の不図示プリント基板をこの下型６に嵌め込んだ後、下型６を元に戻す。このあと、不図示ハンドルを回動する。サーボ駆動であるときは、作動スイッチを押す。これにより、主軸２が回動される。   The method of using the press device 1 of the embodiment is not different from the conventional one. That is, first, with the pressure plate 3 in the standby position (FIGS. 1, 2 and 7A), the lower mold 6 is pulled out and a printed circuit board (not shown) to be processed is fitted into the lower mold 6. After that, the lower mold 6 is returned to its original position. Thereafter, a handle (not shown) is rotated. When in servo drive, press the operation switch. Thereby, the main shaft 2 is rotated.

主軸２回動時の加圧板３等の動きは、図３と図４、図５と図６に順に示される。また、図７（Ｂ）、図８（Ａ）、図８（Ｂ）にも順に示される（図８（Ａ）は主軸２が９０度回動された状態）。即ち、待機角度から主軸２が６６度回動されるまでは、第一のカム１４により加圧板３が押下され、上型４がプリント基板に当接する（図１と図２の状態から図３と図４の状態へ。また、図７（Ａ）から図７（Ｂ））の状態へ。）。   The movement of the pressure plate 3 and the like when the main shaft 2 is rotated is shown in order in FIGS. 3 and 4, and FIGS. 5 and 6. 7B, FIG. 8A, and FIG. 8B are also shown in order (FIG. 8A is a state in which the main shaft 2 is rotated 90 degrees). That is, until the main shaft 2 is rotated 66 degrees from the standby angle, the pressure plate 3 is pushed down by the first cam 14, and the upper die 4 contacts the printed circuit board (from the state of FIGS. 1 and 2 to FIG. 3). 4 to the state of Fig. 4. Also, from the state of Fig. 7A to the state of Fig. 7B. ).

この位置からは、第二のカム１６が作動する。ここで、第二のカム１６は天板９に当接しており、この天板９は固定である。このため第二のカム１６の半径が増加すると、その分、主軸２が下に押下され、これにつれて、加圧板３が下に押下される。これにより、プリント基板が分割されていき、主軸２が１１２度まで回動された迄に分割が完了する（図３と図４の状態から図５と図６の状態へ。また、図７（Ｂ）から図８（Ａ）、そして図８（Ｂ）の状態へ。）。そこで、ハンドルを待機位置に戻す。サーボ駆動のときは、待機位置まで自動的に戻るよう回路を組んでおく。下型６を手前に引き、分割されたプリント基板と枠とを取り出す。   From this position, the second cam 16 operates. Here, the second cam 16 is in contact with the top plate 9, and this top plate 9 is fixed. For this reason, when the radius of the second cam 16 increases, the main shaft 2 is pushed down by that amount, and the pressure plate 3 is pushed down accordingly. As a result, the printed circuit board is divided, and the division is completed until the main shaft 2 is rotated to 112 degrees (from the state shown in FIGS. 3 and 4 to the state shown in FIGS. 5 and 6). (From B) to FIG. 8 (A) and to the state of FIG. 8 (B).) Therefore, the handle is returned to the standby position. During servo drive, a circuit is set up to automatically return to the standby position. The lower mold 6 is pulled forward to take out the divided printed circuit board and frame.

なお、実施の形態例では、第一のカム１４の作動が完了したあとに第二のカム１６が作動を開始するようにした。本発明はこれに限られるものではなく、第一のカム１４の作動完了以前に第二のカム１６が作動を開始するようにしても良い。
また、実施の形態例では、第一のカム１４と第二のカム１６を同じ位置に形成した。本発明はこれに限られるものではなく、第一のカム１４と第二のカム１６を別の位置に形成しても良い。 In the embodiment, the operation of the second cam 16 is started after the operation of the first cam 14 is completed. The present invention is not limited to this, and the second cam 16 may start operating before the operation of the first cam 14 is completed.
In the embodiment, the first cam 14 and the second cam 16 are formed at the same position. The present invention is not limited to this, and the first cam 14 and the second cam 16 may be formed at different positions.

また、実施の形態例では、１本の主軸２に第一のカム１４と第二のカム１６とを形成した。本発明はこれに限られるものではなく、例えば主軸を２本とし、一方の主軸に第一のカム１４を、他方の主軸に第二のカム１６を配置しても良い。第二のカム１６の位置は第一のカム１４の位置と同じにする。
この場合、２本の主軸は天板９と摺動版１２（加圧板３）の間に上下に配置し、第一のカム１４と第二のカム１６とは当接させる。そして、先に一方の主軸を回動して第一のカム１４を６６度回動させ、第二のカム１６と加圧板３とを１７ｍｍ下降させる。次いで、他方の主軸を回動して第二のカム１６を４６度回動させ、加圧版３を３ｍｍ下降させる。
なお、一方の主軸を回動させているとき、他方の主軸にはブレーキを掛けておくと良い。こうすると、第一のカム１４の回動につれて第二のカム１６が回動することが無い。加圧板３と同様の上下動自在の板を第一のカム１４と第二のカム１６との間に介在させても良い。 In the embodiment, the first cam 14 and the second cam 16 are formed on one main shaft 2. The present invention is not limited to this. For example, the number of main shafts may be two, and the first cam 14 may be disposed on one main shaft and the second cam 16 may be disposed on the other main shaft. The position of the second cam 16 is the same as the position of the first cam 14.
In this case, the two main shafts are arranged vertically between the top plate 9 and the sliding plate 12 (pressure plate 3), and the first cam 14 and the second cam 16 are brought into contact with each other. Then, the one main shaft is first rotated to rotate the first cam 14 by 66 degrees, and the second cam 16 and the pressure plate 3 are lowered by 17 mm. Next, the other main shaft is rotated to rotate the second cam 16 by 46 degrees, and the pressure plate 3 is lowered by 3 mm.
It should be noted that when one of the main shafts is rotated, the other main shaft is preferably braked. In this way, the second cam 16 does not rotate as the first cam 14 rotates. A vertically movable plate similar to the pressure plate 3 may be interposed between the first cam 14 and the second cam 16.
