Is provided, and a drive motor 85 for driving the carry-out conveyor 84 is provided. The carry-out conveyor 84 is continuous with the transfer conveyor 91.

Next, the operation will be described. The bound book bundle is placed, for example, manually before the supply position, and the binding string and the upper and lower sheets are removed. Next, the bundle of books is conveyed from the supply position to the standby position by the carry-in conveyor 21 of the carry-in mechanism 20. At this time, the bundle of books is in contact with the stopper member 22, and both sides of the bundle of books are aligned by the aligning member 24.

As shown in FIG. 14, at the start of sorting, the lifting fork 31 of the lifter 30 is at the receiving position, and the moving conveyor 31b moves the book bundle from the standby position to the receiving fork 31. A bundle of books is loaded on top. A bundle of books is a stack of several books with the binding sides alternately.

When the booklet bundle is loaded onto the push-up fork 31, the screw member 37 is rotated by the servo motor 38 and is pushed up via the guide rail 34 for the front-back direction, the slide member 33, and the arm member 32. The fork 31 rises and the bundle of books is lifted from the receiving position. The height of the sorting bundle is calculated from the information about the arbitrary number of books and the thickness information of the books. The pad member 152 for height detection is pushed up to the uppermost book of the book bundle by an amount corresponding to the height of the sorting bundle. Generally, the book thickness is
Numerical value when there is a difference in each cutting surface orthogonal to the binding side,
Also, due to the relationship between the folding restoring force of the signatures that compose a book and the stacking weight pressure, the thickness on the binding side of each book may differ depending on the stacking order. By incorporating the correction value into the function calculation of the bundle height, the dimensional error of the height of the sorting bundle can be reduced. When the bundle of books is lifted to a predetermined position, the sorting claw 40 is
It is a cutting surface orthogonal to the binding side of the lowermost book of the sorting bundle, and is inserted in the center of the cutting surface in the thickness direction. At this time, the dividing claw 40 has the auxiliary claw member 42 in the closed position close to the main claw member 41 as shown by the solid line in FIG. The cylinder member 46 causes the auxiliary claw member 42 to be in the open position as shown by an imaginary line in FIG.

As described above, the dividing claw 40 may be directly inserted into the center of the cutting surface in the thickness direction, but in this embodiment, "120" or the like is used so that the dividing claw 40 can be easily inserted. Has been. That is, the partitioning claw 40 is only applied to the cut surface of the calculated partitioning position, the cylinder member 124 for the supporting member is operated, and the supporting member 120 is orthogonal to the binding side of the sorting bundle via the relay member 122. Then, the cutting surface on the front side is pressed, and the sorting bundle is supported by sandwiching the sorting bundle from both sides by the supporting member 120 and the abutting member 128 corresponding thereto, and then the lifter 30 is lowered to increase the number of the sorting bundle. Also in this case, the insertion resistance of the sorting claw 40 due to the weight pressure of the sorting bundle is reduced. After reducing the weight pressure of the sorting bundle, the sorting claw 40 can be easily inserted.

When the pushing-up fork 31 is lowered by a predetermined amount after the sorting claw 40 is inserted, the lower part of the lowermost book of the sorting bundle below the sorting claw 40 hangs down by its own weight, and the sorting claw 40 is used as a boundary. A book center gap is formed between the upper part of the lowermost book and the lower part of the book. Further, a gap for insertion may be formed between the lowermost book of the sorting bundle and the lower supply bundle, and the sorting plate 50 may be directly inserted into the insertion gap, but in the present embodiment. Uses the photoelectric sensor 100, the sweeping claw 110, and the like so that the partition plate 50 can be easily inserted.

That is, the optical axes of the pair of photoelectric sensors 100 respectively pass through the gaps in the book center, the optical axes of one photoelectric sensor 100 are blocked by the binding side of the lowermost book, and the other photoelectric sensor 100 is blocked. The optical axis goes through the open side of the book at the bottom of the sorting bundle and travels outward without being blocked. A light receiving unit (not shown) provided corresponding to the pair of sweeping claws 110 detects it, and thus the binding side of the book can be detected.

Next, the rocking cylinder 112 corresponding to the binding side of the book is operated, and the wiping claw 110 is moved from the binding side.
Swing to the center line side of the binding side and the opening side. As a result, the hanging portion of the book below the dividing claw 40 inserted in the center of the cutting surface of the lowermost book in the thickness direction is the sweeping claw 1.
It is lifted by 10, and a separation gap is formed between the lower cover lower surface of the lowermost book of the sorting bundle and the upper cover upper surface of the uppermost book of the supply bundle.

The separation gap is formed by further widening the insertion gap. After the separation gap is formed, a partition plate cylinder (not shown) is actuated to separate the partition plate 50. Can move forward to easily insert the partition plate 50 into the separation gap. Since the sorting bundle and the supply bundle are completely separated in the vertical direction by the sorting plate 50, when the sorting bundle is transferred by the pusher member 71 in the next step, the lowermost portion of the sorting bundle and the frictional force are applied. , Care is taken to prevent the supply bundles from being pulled apart.

When the partition plate 50 is inserted into the separation gap, the mounting plate 131 is positioned below the supporting member 51 of the partition plate 50. Next, when the stopper 138 is swung from the restraint position to the restraint release position by the cylinder member 139, the weight of the sorting bundle comes to be applied to the placing plate 131 via the support member 51. The placing plate 131 is biased upward by the restoring force of the spring member 130 corresponding to the calculated weight of the sorting bundle, and if the restoring force of the spring member 130 and the actual load of the sorting bundle are balanced, the placing plate 131 is placed. The placing plate 131 slightly swings, and the sensor shown in the figure detects it, and it is detected that they are in balance.

If the actual load of the sorting bundle is larger,
The step motor 135 is operated, the nut member 134 is rotated through the output gear 135a and the input gear 134a, the screw member 133 is raised, and the spring member 130 is moved.
By increasing the restoring force of the spring member 130, the restoring force of the spring member 130 and the actual load of the sorting bundle are balanced. On the contrary, if the actual load of the sorting bundle is smaller,
The step motor 135 is operated, the nut member 134 is rotated through the output gear 135a and the input gear 134a, the screw member 133 is lowered, and the spring member 130 is moved.
The restoring force of the spring member 130 is set to be low so that the restoring force of the spring member 130 and the actual load of the sorting bundle are balanced.

The restoring force of the spring member 130 and the load of the actual sorting bundle are quickly balanced, and the rotation amount of the disc 136 for pulse generation is detected by the sensor 1 for detecting the rotation angle.
It is possible to quickly detect the sorting bundle of a predetermined number by detecting the sorting bundle 37. Then, the number of sorting bundles can be calculated from the weight value of one book measured in advance. When there is a difference between the number of sorting bundles and the commanded number, the books are replenished or removed to obtain the thickness of the books. The value is also increased or decreased to correct the error.

When the number of book bundles reaches a predetermined number, the cylinder member 72 operates, the pusher member 71 swings from the retracted position to the push-out position, and then the drive mechanism (not shown) operates to push the pusher member. 71 moves horizontally, thereby pushing the sorting bundle out of said sorting position. At this time, since the conveyor of the transfer conveyor 76 is driven,
The sorting bundle is smoothly placed on the side of the conveyor 76.

Further, when the pusher member 71 moves in the horizontal direction, the sorting bundle is placed on the conveying roller 82 of the fork member 81 and moves, and eventually, the sorting bundle comes into contact with the posture correcting plate 78 and its posture is changed. Will be corrected.

Before and after, the pressure belt 79 presses the sorting bundle from above with a constant force so that the posture of the sorting bundle does not collapse. Next, the fork member 81 moves into the guide rail 83.
The sorting bundle is lowered by being guided to, and the sorting bundle is lowered from the posture correction position to the carry-out position, and the sorting bundle is placed on the carry-out conveyor 84. As a result, the sorting bundle is sent to the carry-out conveyor 84, is placed on the side of the carry conveyor 91, and
1 moves to the binding process.

Fork 31 for pushing up one side of the lifter 30
Is moved to the sorting position, the other fork 31 for pushing up is at the receiving position at this time, and the next bundle of books is placed, and the screw member 37 is rotated by the servo motor 38, and the guide rails for the front-back direction are provided. 34-slide member 3
The push-up fork 31 rises via the 3-arm member 32, the bundle of books is lifted from the receiving position, and stops just below one push-up fork 31. Next, one push-up fork 31 is guided by the slide member 33 by the guide rails 34 for the front-rear direction and retracts in the horizontal direction, and the bundle of books on the one push-up fork 31 is rising to the position just below. The push-up forks 31 are stacked on the bundle of books, and the piled-up book bundles are lifted together by the other push-up fork 31.

Further, after the pusher member 71 pushes out the sorting bundle, the pusher member 71 swings to the retracted position and returns to the sorting position while avoiding the next sorting bundle.

The height detecting pad member 152 pushed up by the uppermost book of the sorting bundle is retracted to the side of the sorting bundle by the rotation of the guide rod 150, and is lowered. The motor 156 is operated to drive the belt member 157, the pulley 153, and the timing belt 154.
And the guide rod 150 via the moving base 155.
When it descends to the position corresponding to the uppermost part of the lower supply bundle, the proximity sensor detects it, the lowering motor 156 stops operating, and the height detecting pad member 152.
Stops. Next, the guide rod 150 is rotated again, and the height detecting pad member 152 is placed on the uppermost part of the lower supply bundle.
