のピッチで横方向のミシン目を施すための横ミシン刃を
ミシン胴に固定するための横ミシン刃固定装置に関する
ものである。[Detailed Description of the Invention] [Industrial field of application] The present invention is used in a form printing machine or the like, and a horizontal perforation blade for perforating continuous paper at a constant pitch in a horizontal direction is fixed to a sewing machine cylinder. The present invention relates to a horizontal sewing machine blade fixing device.
上記横ミシン刃固定装置の従来例としては実開昭61-201
799号公報に示されたものがある。As a conventional example of the above-mentioned horizontal sewing machine blade fixing device, the actual machine is shokai 61-201.
There is one disclosed in Japanese Patent No. 799.
この従来例は第5図、第6図に示すようになっていて、

圧着固定するようになっている。This conventional example is as shown in FIG. 5 and FIG.
The slopes a and b are provided on the facing surfaces, and the slopes a and b
A pair of piece pieces e and f having flat surfaces c and d on the opposite side of b are movably accommodated by an appropriate means in a mounting groove h formed in the sewing machine cylinder g by stacking the respective tapered surfaces a and b, and , A sewing machine blade i is interposed between the flat surface c of the one piece piece e and one inner wall of the mounting groove h, and the pair of piece pieces e,
By moving f in the relative direction, the horizontal sewing machine blade i is crimped and fixed to the inner wall of the mounting groove h.
上記従来の横ミシン刃固定装置では、一対の駒片e、f
の相対移動にて横ミシン刃を固定する構成となってお
り、両駒片e、fはその移動方向に長くなっていた。In the above-mentioned conventional horizontal sewing machine blade fixing device, a pair of piece pieces e, f
The horizontal sewing machine blade is fixed by the relative movement of the two pieces, and both piece pieces e and f are elongated in the moving direction.
このため、両駒片e、fのそれぞれの斜面a、bも長く
なり、従ってその全長にわたって両斜面a、bが均等に
接触させるためには高い加工精度を必要とし、その加工
がやっかいであり、精度が悪いとミシン刃の押付力にム
ラが生じるという問題がある。For this reason, the slopes a and b of the two piece pieces e and f also become long, and therefore high machining accuracy is required to make the slopes a and b contact each other evenly over their entire length, and the machining is troublesome. However, if the accuracy is poor, there is a problem that the pressing force of the sewing machine blade becomes uneven.
また斜面a、bが長いことにより、これの勾配がゆるや
かにならざるを得ず、そのためミシン刃iの着脱時にお
ける両駒片e、fの相対移動量が大きくなり、この相対
移動をねじで行う場合、作業時間が長くかかる等の問題
があった。In addition, since the slopes a and b are long, the slope of the slopes must be gentle. Therefore, when the sewing machine blade i is attached or detached, the relative movement amounts of the two pieces e and f become large, and this relative movement can be performed by a screw. When doing, there was a problem that work time was long.

を目的とするものである。The present invention has been made in view of the above, and since the lengths of both slopes of the piece facing each other on the slope are short, both slopes can be easily and accurately processed, and the slope of the slope can be increased. Since the angle can be increased, the relative movement amount of the opposing piece pieces can be reduced, and the effect of being able to perform the attachment / detachment operation of the sewing machine blade in a short time, etc. can be achieved. It is intended to provide.
