Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trimming machine for automatically performing finish trimming in a state where a plurality of books each having a thickness step portion such as an index portion on the edge side are stacked.

[0002]

2. Description of the Related Art Conventionally, in a finish cutting process in a bookbinding process, a three-sided cutting machine is used,
The ground side and edge side are cut with a knife. In this cutting process, generally, a plurality of books are stacked and cutting is performed at one time from the viewpoint of improving processing efficiency.

[0003]

However, the above-mentioned conventional techniques have the following problems. For example, in a book, like a catalog or a title list that lists karaoke song names,
Some books have an index portion protruding from the fore edge side, and for such a book, only the top side and the ground side thereof are finish-cut. Here, the thickness of the general index portion is almost the entire thickness of the book on the top side, but gradually decreases from the top side to the ground side, and on the ground side, a part near the last page of the book. Has only the thickness of.

When a plurality of such books are stacked, there is a gap between the books on the top side of the index portion, but there is a gap between the books on the ground side of the index portion. If the ground side of the book is cut in this state, the index part on the ground side will escape downward in the upper book, and even if it can be cut, the cutting surface (ground surface) will be rough and cut properly. There was a problem that it could not be cut, resulting in defective cutting. Therefore, since there is no choice but to cut the book having such an index portion one by one, it is impossible to cut a large amount in a short time, and there is a problem that a short delivery time cannot be dealt with.

Therefore, the problem to be solved by the present invention is to automatically perform finishing cutting in a state where a plurality of books having a thickness step portion such as an index portion protruding to the fore edge side are stacked.

[0006]

[0008]

In the present invention, a plurality of books are stacked with the thickness step portion facing the carrying-out direction of the books. Further, the receiving portion of the pedestal is inserted into the fore edge side of the stacked books, and the thickness step portion of the top portion or the ground portion is supported by the receiving portion of the pedestal from below. In this state, the top and bottom sides of the stacked books are cut at a time. At the time of cutting, the thickness stepped portion of the top portion or the ground portion of the book is supported by the pedestal, so that it does not escape downward. After cutting, the top and bottom of the book are held by the holding member. Here, since the arm portion on the pedestal side of the holding member is longer than the arm portion on the other side, the book slides in the up-and-down direction (the direction away from the pedestal) due to the holding. Then, if the back of the book is pushed out by the pushing member, the book is carried out without interfering with the pedestal.

And 30B are arranged to face each other on both sides of the main conveyance path 12 at the cutting position of the book 1 in a substantially symmetrical shape. The guide member 32 is a member that extends in the transport direction of the book 1 at the cutting position. Two link members (first link members) 31 are arranged in parallel on each side.
The link member 31 includes two links 31a and 31b, one end of which is rotatably connected to the guide member 32, and the other end of which is fixed to the rotating shaft (first rotating shaft) 37A. The guide member 32 is configured to move in the up-and-down direction of the book 1 (direction orthogonal to the carry-out direction of the book 1) via the link member 31 by the rotation of the rotating shaft 37A. The rail member 33 has a substantially U-shaped cross section, is fitted to the guide member 32, and is provided so as to be slidable along the guide member 32 in the transport direction of the book 1.

The holding member 34 and the pushing member 35 are fixed to the rail member 33 and project toward the main transport path 12 side. The holding member 34 is at the cutting position for the book 1
Of the arm portion 34a that is moved in a direction orthogonal to the conveyance direction of the book 1 and holds the top and bottom portions of the book 1 and is connected to the rail member 33, and a substantially H-shaped rod-shaped body provided at the tip of the arm portion 34a. It is composed of a holding portion 34b. Where pedestal 1
The length of the arm portion 34a of the holding member 34 on the 6 side (the left side in FIG. 7) is formed to be longer than the length of the arm portion 34a of the holding member 34 on the right side. The pushing member 35 is a portion that pushes out the back portion of the book 1 in the carrying-out direction at the cutting position, and is a substantially L-shaped rod-shaped body.

The link member (second link member) 36 has two
One link 36a and 36b, one end of which is rotatably connected to the rail member 33, and the other end of which is fixed to a rotary shaft (second rotary shaft) 37B. Therefore, the rail member 33 is configured to slide via the link member 36 by the rotation of the rotating shaft 37B.

FIG. 8 is a plan view for explaining the operation of the carry-out mechanism section 30. In the figure (a), the book 1 is
The guide members 32 and the rail members 33 on both sides are arranged at substantially central positions. However, as described above, the length L1 of the arm portion 34a of the holding member 34 on the left side is equal to the length of the holding member 34 on the right side.
Is longer than the length L2 of the arm portion 34a (L1> L
2) The holding portion 34b of the left holding member 34 is arranged closer to the book 1 than the right holding portion 34b. That is, when the distances between the left and right sandwiching portions 34b and the book 1 are x1 and x2, respectively, x1 <x2.

When the rotary shaft 37A is rotated in the direction of the figure from the state of (a) in the figure, the link member 31 is driven, and the respective guide members 32 and rail members 33 connected to the link member 31 are connected to the main body 1. Be moved to the side. At the same time, the link member 36 and the rotary shaft 37 are also moved. This allows
In the drawing, the state shown in (b) is reached, and the holding portion 34 of the holding member 34 is held.
The top and bottom portions of the book 1 are clamped by b, and the pushing member 35 is arranged near the back portion of the book 1.

Here, the link members 31 on both sides are driven at the same speed at the same time. However, from the relationship of the distance x1 <x2 described above, the holding portion 34b on the left side first comes into contact with the ground portion of the book 1. The book 1 is contacted, and then the book 1 is slid rightward in the drawing until the right holding portion 34b comes into contact with the top of the book 1.
Therefore, when the top-bottom portion of the book 1 is sandwiched by the sandwiching portions 34b, the book 1 is y = (x2− in the right direction from the initial position (two-dot chain line portion), as shown in FIG. x1) / 2
It is clamped at a position displaced by (for example, about 3.5 mm). At this position, the pedestal 16 is placed within the carry-out range of the book 1.
Will not exist.

Then, from the state of FIG.
The rotary shaft 37B is driven to rotate in the direction shown in FIG.
As a result, the link member 36 is pulled, and the rail member 33 moves along the guide member 32 in the carrying-out direction of the book 1 (in the figure,
Slide down). Therefore, the pushing member 35 fixed to the rail member 33 pushes the back portion of the book 1,
Is moved downward in the figure to be in the state of (c) in the figure. At this time, as described above, since the book 1 is slid to the right in the figure, it does not interfere with the pedestal 16 when being carried out.

After that, if the operation reverse to the above, that is, the rotation shafts 37A and 37B are rotationally driven in the opposite direction, the carry-out mechanism section 30 can be returned to the initial position. By repeating the above operation, the book 1 after cutting can be sequentially carried out to the next step.

Next, a modification of the above embodiment will be described. In the above embodiment, the case where two books 1 are stacked and cut is described. However, depending on the cutting ability of the kitchen knife 22, the thickness of the book 1, the paper quality of the book 1, etc., three or more books may be stacked and cut simultaneously. Is possible. Then, at this time, the pedestal may be formed so as to support the index portions 1a of all the books 1 other than the bottommost book 1. An example of this is shown in FIG. FIG. 9 is a sectional view showing a state in which three books (1A, 1C and 1B) are stacked,
It is a figure corresponding to FIG. In FIG. 9, the pedestal 16 '
Is other than the lower book 1B, that is, the upper book 1A and the intermediate book 1
It is formed so as to support the lower side of the ground portion of each C index portion 1a.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made. (1) In the present embodiment, an example in which the base portion of the index portion 1a of the book 1 is supported by the pedestal 16 is shown, but the present invention can be applied even when the similar index portion 1a is at the top portion. . In this case, the pedestal 16 is attached so as to be arranged below the top of the index portion 1a,
The relationship of the lengths of the respective arm portions 34a of the holding member 34 may be set to be opposite to that of the present embodiment to prevent the interference with the pedestal 16.

(2) Further, when the base of the index portion 1a is not near the last page of the book 1 but at the middle position of the thickness of the book 1, the bottom portion of the stacked books 1 is Even with the book 1, the base portion of the index portion 1a escapes at the time of cutting. Therefore, in this case, the base portion of the index portion 1a of the lowermost book 1 may also be supported by the pedestal 16. (3) FIG. 10 is a perspective view showing a state in which two books 1'which are another form are stacked. In the above-described embodiment, the book 1 having the index portion 1a has been described as an example, but the present invention is not limited to the one having the index portion 1a.
A book 1'having a thickness step portion 1b on the edge side as shown in FIG.
The present invention can be applied to all of the above.

[0031]

As described above, according to the present invention, a book having a thickness step portion on the fore edge side can be properly cut without a thickness step portion escaped in a state where a plurality of books are stacked, and it is automatically carried out. can do. As a result, the time required for the cutting process can be significantly shortened, the bookbinding cost can be reduced, and the delivery time can be shortened. Further, the existing three-way cutting machine can be used to form the cutting machine of the present invention.
