Description of the Related Art A perfect binding bookbinding machine that applies glue to the back of a body and attaches a cover to the back to make a bookbinding product is well known. And in order to finish the bookbinding product created by the bookbinding machine, the top edge, the ground edge and the edge edge of the bookbinding are cut by a cutting machine. As a conventional cutting machine, there exists a thing described in patent document 1, for example. The cutting machine is configured to cut each edge of the bookbinding product by moving the cutting blade in the vertical direction. As shown in FIG. 7 of Patent Document 1, the cutting blade 1 is moved up and down in an oblique direction to reduce the load on the cutting edge of the cutting blade 1.

また、特許文献１の図９に示すとおり、断裁刃１で製本物４の天辺縁部４ｃおよび地辺縁部４ｄを断裁する際、断裁刃１が製本物４の小口４ａの方向から進入して断裁すると、製本物４の背面４ｂに返りが発生して乱れが生じる問題がある。そこで、特許文献１の断裁機は、断裁刃１で製本物４の天辺縁部４ｃおよび地辺縁部４ｄを断裁する際に、断裁刃１の進入方向を変更できるようになっており、製本物４を裏返すことなく、断裁刃１が製本物４の背面４ｃから進入して断裁できる。 Further, as shown in FIG. 9 of Patent Document 1, when the top edge 4c and the ground edge 4d of the bookbinding product 4 are cut with the cutting blade 1, the cutting blade 1 enters from the direction of the edge 4a of the bookbinding product 4.

三方断裁機は、搬送機構１８で製本物２７を所定の断裁位置に搬送し、その後、押さえ部材１５ａ〜１５ｃで製本物を押さえる。そして、三方断裁機は、製本物２７の天辺縁部２７ａおよび地辺縁部２７ｂを断裁する際に、搬送機構１８で製本物２７を所定の断裁位置に搬送し、断裁位置に搬送された製本物２７を一対の押さえ部材１５ａ，１５ｂで押さえて、製本物２７を押さえている間に、天用断裁刃１１および地用断裁刃１２で製本物２７の天辺縁部２７ａおよび地辺縁部２７ｂを断裁する。 The three-way cutting machine transports the bookbinding product 27 to a predetermined cutting position by the transport mechanism 18 and then presses the bookbinding product by the pressing members 15a to 15c. When the three-side cutting machine cuts the top edge portion 27a and the ground edge portion 27b of the bookbinding product 27, the bookbinding device 27 transports the bookbinding product 27 to a predetermined cutting position by the transport mechanism 18, and the bookbinding material transported to the cutting position. While the object 27 is pressed by the pair of pressing members 15a and 15b and the bookbinding object 27 is being pressed, the top edge 27a and the edge 27b of the bookbinding 27 by the top cutting blade 11 and the ground cutting blade 12 are shown. Cut out.

特許文献２の三方断裁機では、押さえ部材１５ａ，１５ｂは、製本物２７の背面にわたって押さえている。しかし、押さえ部材１５ａ，１５ｂが製本物２７の背面を押さえると、製本物の背面に皺が入り、仕上がりのよい製本物２７ができない場合があった。
また、押さえ部材１５ａ，１５ｂが製本物２７の背面を避けるように押さえて、天用断裁刃１１および地用断裁刃１２で製本物２７の天辺縁部２７ａおよび地辺縁部２７ｂを断裁すると、製本物２７の背面の角が破れることがあった。 In the three-way cutting machine of Patent Document 2, the pressing members 15 a and 15 b are pressed over the back surface of the bookbinding product 27. However, when the pressing members 15a and 15b press the back side of the bookbinding product 27, there are cases where a booklet 27 with a good finish cannot be made due to a wrinkle on the back surface of the bookbinding product.
Further, when the pressing members 15a and 15b are pressed so as to avoid the back side of the bookbinding product 27, and the top edge portion 27a and the ground edge portion 27b of the bookbinding product 27 are cut with the top cutting blade 11 and the ground cutting blade 12, The corner of the back surface of the bookbinding product 27 may be broken.

＜天地断裁動作＞
次に、三方断裁機が製本物２７の天辺縁部２７ａ及び地辺縁部２７ｂを断裁する際の動作について詳細に説明する。 <Head cutting operation>
Next, the operation when the three-way cutting machine cuts the top edge 27a and the ground edge 27b of the bookbinding product 27 will be described in detail.

本実施形態では、入力部２は、タッチパネルで構成されており、図１の通り、製本物２７を第１断裁位置に搬送するように指示するための第１指示ボタン２ａと、製本物２７を第２断裁位置に搬送するように指示するための第２指示ボタン２ｂとが、入力部２に表示されるようになっている。そして、作業者が入力部２を通じて製本物２７を第１又は第２断裁位置に搬送するように指示すると、その指示信号が入力部２から制御部１に送られ、制御部１は、入力部２からの指示信号に基づいて、搬送機構１８を駆動する。 In the present embodiment, the input unit 2 is configured by a touch panel. As shown in FIG. 1, the input unit 2 includes a first instruction button 2 a for instructing to transport the bookbinding product 27 to the first cutting position, and the bookbinding product 27. A second instruction button 2b for instructing conveyance to the second cutting position is displayed on the input unit 2. When the operator instructs to transport the bookbinding product 27 to the first or second cutting position through the input unit 2, the instruction signal is sent from the input unit 2 to the control unit 1, and the control unit 1 Based on the instruction signal from 2, the transport mechanism 18 is driven.

＜第１断裁位置＞
作業者が入力部２の第１指示ボタン２ａを押すと、搬送機構１８は、製本物２７を小口断裁部１ｃから天地断裁部１ｄにおける第１断裁位置へ搬送して停止する。 <First cutting position>
When the operator presses the first instruction button 2a of the input unit 2, the transport mechanism 18 transports the bookbinding product 27 from the fore edge cutting unit 1c to the first cutting position in the top and bottom cutting unit 1d and stops.

図５（Ａ）の通り、製本物２７が第１断裁位置で停止すると、天用押さえ板１５ａ及び地用押さえ板１５ｂの前端面１５０から前方へ所定距離Ｓだけ間隔を置いた位置に、製本物２７の背面２７ｄを配置する。なお、搬送機構１８のチャック機構１８０は、製本物２７の背面２７ｄを把持しないように、製本物２７を把持する。 As shown in FIG. 5A, when the bookbinding product 27 stops at the first cutting position, the bookbinding is performed at a position spaced a predetermined distance S forward from the front end surfaces 150 of the top pressing plate 15a and the ground pressing plate 15b. A back surface 27d of the object 27 is arranged. The chuck mechanism 180 of the transport mechanism 18 grips the bookbinding product 27 so as not to grip the back surface 27d of the bookbinding product 27.

その後、図５（Ｂ）の通り、製本物２７が第１断裁位置で停止している間に、押さえ板駆動モータ２６が駆動して、それによって、天用押さえ板１５ａ及び地用押さえ板１５ｂが、製本物２７から離れた非押圧位置（図５（Ａ））から製本物２７を押さえる押圧位置（図５（Ｂ））に移動する。非押圧位置と押圧位置との位置関係は、予め設定されており、本実施形態では、押さえ板１５ａ，１５ｂは、垂直方向に移動するようになっている。その結果、押圧位置に配置された天用押さえ板１５ａ及び地用押さえ板１５ｂは、製本物２７の背面２７ｄが押さえられないように、製本物２７を押さえるようになっている。 Thereafter, as shown in FIG. 5B, while the bookbinding product 27 is stopped at the first cutting position, the presser plate drive motor 26 is driven, whereby the top presser plate 15a and the ground presser plate 15b. However, it moves from the non-pressing position (FIG. 5 (A)) away from the bookbinding product 27 to the pressing position (FIG. 5 (B)) for pressing the bookbinding product 27. The positional relationship between the non-pressing position and the pressing position is set in advance, and in this embodiment, the pressing plates 15a and 15b are moved in the vertical direction. As a result, the top pressing plate 15a and the ground pressing plate 15b arranged at the pressing position press the bookbinding product 27 so that the back surface 27d of the bookbinding product 27 is not pressed.

製本物２７は、本身２７０と表紙２７１とを備えており、本身２７０の背面に糊が塗布されて、その背面に表紙２７１が貼り付けられている。製本物２７の背面２７ｄの厚さＷ１が、本身２７０の厚さＷ２よりも厚くて、厚さＷ１と厚さＷ２との差が所定の閾値よりも大きい場合、押さえ部材１５ａ，１５ｂが製本物２７の背面２７ｄを押さえると、押さえた時に、製本物２７の背面２７ｄが潰れて皺が入り、仕上がりのよい製本物ができない。従って、その場合には、作業者は入力部２の第１指示ボタン２ａを押して、製本物２７を第１断裁位置に搬送して、押さえ板１５ａ，１５ｂが製本物２７の背面２７ｄを押さえず、製本物２７の背面２７ｄに皺が入らないようにする。 The bookbinding product 27 includes a body 270 and a cover 271, glue is applied to the back of the body 270, and the cover 271 is attached to the back. When the thickness W1 of the back surface 27d of the bookbinding product 27 is larger than the thickness W2 of the body 270 and the difference between the thickness W1 and the thickness W2 is larger than a predetermined threshold value, the pressing members 15a and 15b are bound to the bookbinding product. When the back surface 27d of 27 is pressed, the back surface 27d of the bookbinding product 27 is crushed and wrinkled, and a bookbinding product with a good finish cannot be made. Therefore, in this case, the operator presses the first instruction button 2a of the input unit 2 to convey the bookbinding product 27 to the first cutting position, and the pressing plates 15a and 15b do not press the back surface 27d of the bookbinding product 27. , So that no wrinkles enter the back surface 27d of the bookbinding product 27.

そして、押さえ板１５ａ，１５ｂが製本物２７の背面２７ｄを避けるように押さえている間に、制御部１は、断裁刃駆動モータ２２を駆動して、それによって、天用断裁刃１１及び地用断裁刃１２を非断裁位置から断裁位置へ斜め方向に降ろす。その結果、製本物２７の天辺縁部２７ａ及び地辺縁部２７ｂが断裁されるようになっている。
なお、断裁刃１１，１２は、製本物２７の背面２７ｄから進入して、斜め方向に断裁することで、断裁刃１１，１２の刃先にかかる負担を軽減し、仕上がりのよい製本物２７になるように断裁する。 The control unit 1 drives the cutting blade drive motor 22 while the pressing plates 15a and 15b are pressed so as to avoid the back surface 27d of the bookbinding product 27, thereby the top cutting blade 11 and the ground cutting blade. The cutting blade 12 is lowered in an oblique direction from the non-cutting position to the cutting position. As a result, the top edge 27a and the ground edge 27b of the bookbinding product 27 are cut.
In addition, the cutting blades 11 and 12 enter from the back surface 27d of the bookbinding product 27 and cut in an oblique direction, thereby reducing the burden on the cutting edges of the cutting blades 11 and 12, and the bookbinding product 27 having a good finish. Cut as follows.

＜第２断裁位置＞
作業者が入力部２の第２指示ボタン２ｂを押すと、搬送機構１８は、製本物２７を小口断裁部１ｃから天地断裁部１ｄにおける第２断裁位置へ搬送して停止する。 <Second cutting position>
When the operator presses the second instruction button 2b of the input unit 2, the transport mechanism 18 transports the bookbinding product 27 from the small edge cutting unit 1c to the second cutting position in the top and bottom cutting unit 1d and stops.

図６（Ａ）の通り、製本物２７が第２断裁位置で停止すると、天用押さえ板１５ａ及び地用押さえ板１５ｂの前端面１５０の真下（又は、真下より前方）に、製本物２７の背面２７ｄが配置される。 As shown in FIG. 6 (A), when the bookbinding product 27 stops at the second cutting position, the bookbinding product 27 is placed directly under the front end face 150 of the top plate 15a and the ground plate 15b (or forward from directly below). A back surface 27d is arranged.

その後、図６（Ｂ）の通り、製本物２７が第２断裁位置で停止している間に、押さえ板駆動モータ２６が駆動して、それによって、天用押さえ板１５ａ及び地用押さえ板１５ｂが、製本物２７から離れた非押圧位置（図６（Ａ））から製本物２７を押さえる押圧位置（図６（Ｂ））に移動する。その結果、押圧位置に配置された天用押さえ板１５ａ及び地用押さえ板１５ｂは、製本物２７の背面２７ｄが押さえられるように、製本物２７を押さえるようになっている。 Thereafter, as shown in FIG. 6B, while the bookbinding product 27 is stopped at the second cutting position, the presser plate drive motor 26 is driven, whereby the top presser plate 15a and the ground presser plate 15b. However, it moves from the non-pressing position (FIG. 6 (A)) away from the bookbinding product 27 to the pressing position (FIG. 6 (B)) for pressing the bookbinding product 27. As a result, the top pressing plate 15a and the ground pressing plate 15b arranged at the pressing position press the bookbinding product 27 so that the back surface 27d of the bookbinding product 27 is pressed.

製本物２７の背面２７ｄの厚さＷ１と本身２７０の厚さＷ２との差が所定の閾値よりも小さい場合、押さえ部材１５ａ，１５ｂが製本物２７の背面２７ｄを押さえても、押さえた時に、製本物２７の背面２７ｄに皺が入らない。従って、その場合には、作業者は入力部２の第２指示ボタン２ｂを押して、製本物２７を第２断裁位置に搬送して、押さえ板１５ａ，１５ｂが製本物２７の背面２７ｄを押さえて、製本物２７の背面２７ｄの角が破れないようにする。 When the difference between the thickness W1 of the back surface 27d of the bookbinding product 27 and the thickness W2 of the body 270 is smaller than a predetermined threshold value, the pressing members 15a and 15b hold the back surface 27d of the bookbinding product 27 even when they are pressed. No wrinkles enter the back surface 27d of the bookbinding product 27. Therefore, in this case, the operator presses the second instruction button 2b of the input unit 2 to convey the bookbinding product 27 to the second cutting position, and the pressing plates 15a and 15b press the back surface 27d of the bookbinding product 27. The corners of the back surface 27d of the bookbinding 27 are not torn.

そして、押さえ板１５ａ，１５ｂが製本物２７を押さえている間に、制御部１は、天用断裁刃１１及び地用断裁刃１２を非断裁位置から断裁位置へ斜め方向に降ろす。その結果、製本物２７の天辺縁部２７ａ及び地辺縁部２７ｂが断裁されるようになっている。 Then, while the pressing plates 15 a and 15 b are pressing the bookbinding product 27, the control unit 1 lowers the top cutting blade 11 and the ground cutting blade 12 from the non-cutting position to the cutting position in an oblique direction. As a result, the top edge 27a and the ground edge 27b of the bookbinding product 27 are cut.
