And a drive motor 85 for driving the unloading conveyor 84 is provided. The transport conveyor 91 is continuous with the unloading conveyor 84.

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 book bundle 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 book bundle is in contact with the stopper member 22, and both sides of the book bundle are aligned by the alignment member 24.

As shown in FIG. 2, at the start of sorting, the lifting fork 31 of the lifter 30 is at the receiving position, and the moving conveyer 31b moves the book bundle from the standby position to the receiving position. A bundle of book books is carried in. The book bundle is obtained by alternately stacking the binding side every several books.

When the book bundle is loaded onto the lifting fork 31, the screw member 37 is rotated by the servo motor 38, and the lifting member 37 is rotated via the guide rail 34, the sliding member 33, and the arm member 32 for forward and backward directions. The fork 31 rises, and the booklet bundle is lifted from the receiving position. The height of the sorting bundle is calculated from the commanded arbitrary number of books and the book thickness information. 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 thickness of the book is
Numerical values when there is a difference between each of the cutting surfaces orthogonal to the binding side,
Also, due to the relationship between the fold restoring force of the signatures constituting the book and the stacking weight pressure, there is a difference in the thickness of the binding side of each book according to the stacking order. By incorporating the correction value into the function calculation of the bundle height, the dimensional error of the height of the sorted bundle can be reduced. When the book bundle is lifted to a predetermined position, based on the calculated numerical values, the sorting claws 40
The cutting surface is orthogonal to the binding side of the lowermost booklet of the sorting bundle, and is inserted into the center of the cutting surface in the thickness direction. At this time, the separating claw 40 is in the closed position where the sub-claw member 42 is close to the main claw member 41 as shown by a solid line in FIG. 4 to reduce resistance at the time of insertion. The sub-claw member 42 is brought to the open position as shown by the imaginary line in FIG.

As described above, the dividing claw 40 may be directly inserted into the center of the cut surface in the thickness direction. However, in this embodiment, the support member 120 and the like are provided so that the dividing claw 40 can be easily inserted. Used. In other words, the separating claw 40 is only applied to the cut surface at the calculated separating position, and the cylinder member 124 for the supporting member is operated, so that the supporting member 120 intersects perpendicularly to the binding side of the sorting bundle via the relay member 122. The cutting surface on the front side of the sorting bundle is pressed, and the supporting member 120 and the corresponding contact member 128 support the sorting bundle so as to sandwich the sorting bundle from both sides, and then lower the lifter 30 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 push-up fork 31 is lowered by a predetermined amount after the sorting claw 40 is inserted, the lower part of the lowermost booklet of the sorting bundle below the sorting claw 40 hangs down by its own weight, and the separation claw 40 is bordered. A book center gap is formed between the upper part of the lowermost book and the lower part of the book. Further, an insertion gap is formed between the lowermost booklet of the sorting bundle and the lower supply bundle, and the separating plate 50 may be inserted directly into the insertion gap. Is designed so that the separating plate 50 can be easily inserted by using the photoelectric sensor 100 and the wiping claw 110.

That is, the optical axes of the pair of photoelectric sensors 100 pass through the booklet center gap, the optical axis of one photoelectric sensor 100 is blocked by the binding side of the lowermost book, and the other photoelectric sensor 100 Travels outward without being blocked by the open side of the bottom booklet of the sorting bundle. A light receiving unit (not shown) provided corresponding to the pair of wiping claws 110 detects this, thereby detecting the binding side of the book.

Next, the swinging cylinder 112 corresponding to the binding side of the book is operated, and the wiping claw 110 is moved from the binding side.
It swings to the center line side of the binding side and the opening side. As a result, the hanging portion of the booklet below the separating claw 40 inserted into the center of the cut surface of the lowermost booklet in the thickness direction becomes the wiping nail 1.
10, a separation gap is formed between the lower surface of the lower cover of the lowermost book of the sorting bundle and the upper surface of the cover of the uppermost book of the supply bundle.

The separation gap is such that the insertion gap is further widened. After the separation gap is formed, the separation plate cylinder (not shown) is operated, and the separation plate 50 is formed. Moves forward, and the partition plate 50 can be easily inserted into the separation gap. Since the sorting bundle and the supply bundle are completely separated in the vertical direction by the sorting plate 50, in the next step, when the sorting bundle is transferred by the pusher member 71, by the lowermost part of the sorting bundle and the frictional force, Care is taken to prevent the supply bundle from being dragged.

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

If the load of the actual sorting bundle is larger,
By operating the step motor 135, 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 rotated.
, So that the restoring force of the spring member 130 and the actual load of the sorting bundle are balanced. Conversely, if the actual weight of the sorting bundle is smaller,
By operating the step motor 135, the nut member 134 is rotated via the output gear 135a and the input gear 134a, the screw member 133 is lowered, and the spring member 130 is moved.
Is reduced 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 actual load of the sorting bundle are quickly balanced, and the rotation amount of the pulse generating disk 136 is used as a sensor 1 for detecting the rotation angle.
As a result, a predetermined number of sorted bundles can be quickly detected. Then, the number of the sorted bundles can be calculated from the previously measured weight value of one book. If there is a difference between the number of the sorted bundles and the number of the ordered books, the books are replenished or removed, and the thickness of the books is reduced. The numerical value also increases or decreases to correct the error.

When the number of book bundles reaches a predetermined number, the cylinder member 72 operates to push the pusher member 71 from the retracted position to the extrudable position, and then a drive mechanism (not shown) is operated to push the pusher member. 71 moves in the horizontal direction, whereby the sorting bundle is pushed out of the sorting position. At this time, since the conveyor of the transport conveyor 76 is being driven,
The sorted bundle smoothly comes on the conveyor 76 side.

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

Before and after, the pressing 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 is moved to the guide rail 83.
The sorting bundle is lowered from the posture correction position to the unloading position, and the sorted bundle is placed on the unloading conveyor 84. As a result, the sorted bundle is sent out to the unloading conveyor 84 and is placed on the side of the transporting conveyor 91, where
The process moves to the binding step by 1.

One lifting fork 31 of the lifter 30
Rises to the sorting position, at this time, the other push-up fork 31 is at the receiving position and the next book bundle is loaded, and the screw member 37 is rotated by the servomotor 38 to guide the front-back guide rail. 34-slide member 3
The lifting fork 31 is raised via the third to arm members 32, the book bundle is lifted from the receiving position, and stops just below one of the lifting forks 31. Next, one push-up fork 31 is guided by the guide member 34 for the front-rear direction by the slide member 33 and retreats in the horizontal direction, and the book bundle on the one push-up fork 31 is raised to just below the other. The book bundle of the lifting fork 31 is stacked on the book bundle, and the overlapped book bundle is raised together by the other lifting fork 31.

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

The height detecting pad member 152 pushed up by the uppermost booklet of the sorting bundle retreats to the side of the sorting bundle and lowers by the rotation of the guide rod 150. Motor 156 operates, and the belt member 157, the pulley 153, the timing belt 154
And the guide rod 150 via the moving base 155.
When it descends to a position corresponding to the uppermost part of the lower supply bundle, the proximity sensor detects that the lowering motor 156 stops operating, and the height detecting pad member 152
Stops. Next, the guide rod 150 rotates again, and the pad member 152 for height detection comes to rest on the uppermost part of the lower supply bundle.

[0049]

According to the book bundle sorting method of the present invention, a separating claw is inserted into the lowermost book bundle of the sorting bundle to form an insertion gap between the sorting bundle and the lower supply bundle. As the sorting plate is inserted in the insertion gap and the sorting bundle is transported, it is not necessary to carry out the books one by one, and the sorting time is shorter than when the books are carried out one by one.

Claims (6)

(57) [Claims] 1. A bundle of books stacked alternately on the binding side for every several books is supplied from below to above by a lifter, and the supplied bundle of books is supplied based on arbitrary commanded number of books information. A sorting method for a book bundle in which a sorting bundle and a supply bundle are vertically separated and sequentially sorted into a predetermined number of books, wherein the booklet bundle information is obtained from the book thickness information and the book number information. The height is calculated, and a separating claw is inserted into the center of the cut surface orthogonal to the binding side of the lowermost booklet of the sorting bundle in the thickness direction of the cutting surface, and the separating claw and the lower supply bundle are inserted. Are separated in the up-down direction, so that a gap for insertion is formed between the lower surface of the cover on the binding side of the lowermost book and the upper surface of the cover of the supply bundle, and a separating plate is inserted into the clearance for insertion. After separating the sorting bundle and the supply bundle in the vertical direction, the sorting Saku the flux method sorting, characterized in that so as to transfer the bundle. 2. The optical axis of a pair of photoelectric sensors provided below a place where the sorting claw is on standby is inverted with respect to a center line between a binding side of the book and an opening side opposite to the binding side. In a C-shape and in the horizontal direction, the separating claw and the lower supply bundle are vertically separated from each other, and the hanging part of the booklet lower than the separating claw inserted into the center of the cutting surface in the thickness direction. Is lifted from the binding side to the center line side of the book by the wiping nail, and the lowermost book is the same as the upper part of the lowermost book with the dividing nail as a boundary. It is made to pass through the booklet center gap formed between the lower part of the booklet, and one of the optical axes of the pair of photoelectric sensors is blocked by the binding side of the lowermost booklet. The binding side of the lower booklet is detected. The method for sorting book bundles according to claim 1. 3. A lifting part of a book hanging below the separating claw inserted into the center in the thickness direction of the cutting surface so as to be moved from the binding side toward the center line side of the book by a removing claw. After forming a separation gap between the lower surface of the lower cover of the lowermost book of the sorting bundle and the upper surface of the cover of the uppermost book of the supply bundle, the separation into the separation gap is performed. 3. The method according to claim 1, wherein a plate is inserted. 4. A numerical value in the case where the thickness of the book has a difference in each of the cut surfaces orthogonal to the binding side, and a relation between a fold restoring force of a signature included in the book and a stacking weight pressure. From
By taking the numerical value when there is a difference in the thickness of the binding side of each book according to the stacking order as a correction value in the function calculation of the height of the sorting bundle, it is possible to reduce the dimensional error of the height of the sorting bundle. The method according to claim 1, wherein
2. The method for sorting book bundles according to 2 or 3. 5. The method according to claim 5, wherein the sectioning claw is applied to a cutting section at the calculated sectioning position, and a contact member is brought into contact with a cutting section of each book on a side opposite to a cutting section into which the support member presses. Even when the number of books in the sorting bundle increases, the weight of the sorting bundle causes the insertion resistance of the sorting claw to be supported by sandwiching the sorting bundle above the sorting position with the contact member. 5. The method according to claim 1, wherein the sorting claw is inserted after reducing the number of booklets. 6. After the sorting plate is inserted, the weight of the sorting bundle placed on the sorting plate is measured, and the number of the sorting bundle is calculated from the weight value of one book measured in advance.
When there is a difference from the command number, the book is replenished or removed, and the thickness information of the book can be corrected to prevent the thickness error of the book from recurring. Item 1. The method for sorting a book bundle according to Item 1, 2, 3, 4, or 5.
