DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing book stacking apparatus used for forming a printing book bundle by stacking prints discharged in a sashimi form from a rotary printing press or a folding machine. .

[0002]

2. Description of the Related Art Generally, a book discharged from a rotary printing press or a folding machine is conveyed in a sashimi form on a conveyor, but in a normal case, this book is convenient for transportation and handling in a later process. So that they can be bundled together. For this reason, conventionally, a print book stacking device as shown in FIG. 13 is used. This print book stacking apparatus transfers a print book P conveyed in a sashimi shape by a transfer conveyor 31 between an introduction belt row composed of a back side belt row 32 and a release side belt row 33 which rotate in the vertical direction. , And is introduced in an upright state on a stacking table 35 provided with a relief belt 34, and the booklets P are sequentially stacked on the stacking table 35 between the rear side belt row 32 and the retreating support member 36. Yes, the formed book bundle T is then bound or transferred in a case as required.

In the above-mentioned conventional printing book stacking apparatus, the following means are taken for separating the printing book bundle T formed on the stacking table 35. One is to provide a set-off mechanism for temporarily blocking the flow of the sashimi-conveyed prints P, thereby forming a gap without the prints P in the sashimi row to divide the print book bundle T. At present, a printing book stacking apparatus using this set-off mechanism has become mainstream. Further, a set of vibrating spatula-shaped skewer is provided so as to protrude from below the accumulation table 35, and the spatula-shaped skewer is inserted into the stacked printing book bundle T and divided into a predetermined number of copies. Such a printed book stacking apparatus is also used.

[0004]

In the former of the techniques described in the prior art, when the flow of the book is stopped by the settling mechanism, lumps are generated in the sashimi row, so that the bundle of the printed books to be collected is This is also a cause of misalignment of the booklet bundle because the sashimi thickness changes before and after the gap blocking the sashimi line, and the accumulation pressure of the booklet bundle changes significantly. There was a problem of becoming. On the other hand, in the latter method, the booklet may be damaged at the stage of inserting a spatula-shaped skewer. There has been a problem that the number of copies in a bundle becomes inaccurate.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks and problems of a conventional printing book stacking apparatus. It is an object of the present invention to form a printing book bundle with good uniformity. It is an object of the present invention to provide a print book stacking apparatus that can surely divide a print book into a predetermined number of copies without damaging the print book.

[0006]

In order to achieve the above object, a printing book stacking apparatus according to the present invention comprises a stacking table having a relief belt and a printing book conveyed in a sashimi shape by a conveying conveyor in an upright state. An introduction belt configured by combining a back-side belt row that rotates through the accumulation table and a release-side belt row that opposes the back-side belt row and rotates above the accumulation table for introduction onto the accumulation table. In order to accumulate the print book between the row and the back side belt row on the stacking table, the stack is protruded above the stacking table and is arranged so as to be able to move forward and backward facing the back side belt row. in book blocks integrated device formed by and a support member, thorn

In the above-mentioned printing book stacking apparatus, a belt is provided so as to go around each of the sorting skewers, and both ends of the belt are fixed to the support frame of the sorting skewers at substantially the same positions outside the sorting skewers. Alternatively, a belt may be provided along the outer periphery of each division skewer, and one end of the belt may be fixed to the support frame of the division skewer outside the division skewer, and the other end may be raised and lowered. You may make it elastically support inside a division skewer so that it may not block.

[0008]

The printing book conveyed in a sashimi form from the printing press is introduced onto the accumulation table by the introduction belt row. The printed books introduced on the stacking table are dammed on the stacking table one by one in order. Therefore, at the accumulation point, the end face of the book is visible for a maximum of one pitch of the sashimi from the time when a certain book is blocked to the time when the next book is blocked. Therefore, at the moment when a predetermined number of copies are accumulated and the last booklet of one bundle reaches the accumulation table, a guide skewer shorter than one pitch of the sashimi is slid from behind the back side belt to remove the visible booklets. Insert along the end face. The timing of inserting the guide skewers is not strict, and if the guide skewers are shorter than one pitch, the printed book will reach the accumulation table without stopping halfway. An optical displacement sensor may be provided in the immediate vicinity of the stacking point, and the operation of the guide skewer may be controlled by detecting the timing at which each printing book touches the stacking table. After this, the prints continue to flow, but the guide skewer that holds the bundle of prints is thin enough so that the subsequent prints are stacked on the stacking table as before with the guide skewer in between. A new bundle of printing books is formed behind the guide skewers. After insertion,
Since the guide skewer can be freely slid, it does not become an obstacle for stacking subsequent prints.

The guide skewer is inserted in a form in which one or more skewers are joined together, and separates when the influence of the stacking portion is eliminated, thereby dividing the lower part of the book bundle. The printing skewers are completely separated by raising the sorting skewers between the guide skewers divided into right and left. The guide skewer retracts below the stacking table surface and returns to the rear of the rear belt row without interfering with the subsequent bundle. The sorting skewer sends the sorted bundle of prints to a binding device generally provided downstream of the stacking device, and then retracts below the stacking table surface, to a position below a position where the stack is separated without interfering with a succeeding bundle. Return to the standby position. The booklets are collected by the above-described sequence of operations.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view showing an embodiment of a print book stacking apparatus according to the present invention.

In FIG. 1, reference numeral 1 denotes an accumulation table having an escape belt 2 running on the same surface. Reference numeral 3 denotes a back side belt row that rotates while passing through the stacking table 1, and 4 denotes a release side belt row that faces the back side belt row 3 and rotates above the stacking table 1. In the row, the printing books P conveyed in a sashimi shape by the conveyor are introduced into the stacking table 1 in an upright state.
A support member 5 is disposed on the stacking table 1 so as to be able to move forward and backward facing the back side belt row 3 in a state of being protruded upward, and the support member 5 is moved backward on the stacking table 1. Then, the prints P are accumulated between the belt belt 3 and the rear side. That is, the printing books P introduced on the stacking table 1 are blocked on the upper surface of the stacking table 1 and are sequentially stacked on the release side to form a printing book bundle T.

Reference numeral 6 denotes a pair of openable and closable guide skewers, which are supported by a guide skewer unit movable along the stacking table 1. In the standby position shown in FIG. And protrudes upward from the accumulation table 1 surface. Further, reference numeral 7 denotes a set of sorting skewers which can be moved up and down and which can be opened and closed, which are also supported by a sorting skewer unit movable along the stacking table 1, and which are arranged at the standby position shown in FIG. It is located below one surface.
Reference numeral 8 denotes a top plate provided near the lower end of the release-side belt row 4.

The bundle of printing books T being collected on the stacking table 1 is sandwiched between the back side belt row 3 and the supporting member 5, and the supporting member 5 is retracted as the number of printing book bundles T increases. Then, when the predetermined number of copies are counted, as shown in FIG. 2, the guide skewer 6 is inserted into the stacking unit from behind the back side belt row 3 in parallel with the stacking table 1. Since the sashimi-shaped printing book P flows even after the guide skewers 6 are inserted, as shown in FIG. 3, the support member 5 is retreated while forming the next printing book bundle T ′. The supporting guide skewer unit can be freely slid parallel to the stacking table 1,
The guide skewer 6 does not hinder the formation of the next bundle of prints T '. In this way, when the accumulation of the printing books P progresses and the guide skewer 6 comes above the sorting skewer 7, the guide skewer 6 is opened to the front and rear guide skewers 6a and 6b as shown in FIG. In this case, since the standby position of the sorting skewers 7 is sufficiently far from the back side belt row 4, the lower part of the booklet bundles T, T 'can be divided without obstructing the formation of the next booklet bundle T'. Next, as shown in FIG. 5, the divided skewer 7 in the closed state is raised and inserted between the opened guide skewers 6a and 6b. Thus, a predetermined number of book bundles T can be separated. In addition, since there is a possibility that the book P in contact with the sorting skewers 7 may be rubbed and lifted when the sorting skewer 7 is lifted, in this embodiment, a top plate 8 is provided to prevent the book from being lifted. The sorting skewers 7 thus inserted are opened to the front and rear sorting skewers 7a and 7b to separate the printing book bundles T and T 'as shown in FIG. That is, the front sorting skew 7a supports the back of the printing book bundle T to sandwich the printing book bundle T with the support member 5, and the rear sorting skew 7b supports the front of the printing book bundle T '. Then, the prints P are accumulated with the back belt row 4. Thereafter, the guide skewers 6a and 6b are retracted below the surface of the stacking table 1 and returned to the standby position after the back side belt row 4. On the other hand, after the sorted printing book bundle T is transferred to a subsequent process for binding or the like using the take-out hand 9 as shown in FIG. 6, for example, the printing book bundle T ′ being accumulated is pressed. The rear division skew 7b and the support member 5 are replaced, and each division skew 7
