Description

This invention relates to a method and apparatus for reversing ring-bound books. In the manufacture of desk calendars, as shown in Figure 1(a), a ring-shaped binder 6 is attached to a base sheet 2 formed by folding cardboard in half, with multiple calendar sheets 4 laminated on the back side 2a. Then, the base sheet 2 and the calendar sheets 4 are rotated in the direction indicated by the arrows so that the adhesive portion 6a of the ring-shaped binder 6 is covered by the calendar sheets 4, resulting in the calendar sheets 4 being laminated on the front side 2b of the base sheet 2, as shown in Figure 1(b). A device for reversing the lamination direction of the calendar sheets 4 on the base sheet 2 is known, as disclosed in Patent Document 1. This reversing device is equipped with a multi-joint robot that grips the edge of the ring-bound booklet's backing sheet opposite to the ring binder using a chuck at the tip of its arm. The multi-joint robot, with the ring-bound booklet upright, accelerates the chuck horizontally in the direction opposite to the paper stacking direction on the backing sheet, then decelerates, causing the paper to rotate due to inertia, thereby reversing the paper stacking direction on the backing sheet. Patent No. 6789575 This is a side view of a ring-bound book.This is a plan view of a reversing device for ring-bound books according to one embodiment of the present invention.Figure 2 is a perspective view of the main part of the reversing device for ring-bound books.Figure 2 is a schematic diagram illustrating the operation of the reversing device for ring-bound books. Figure 2 is a plan view of a ring-bound book reversing device according to one embodiment of the present invention. As shown in Figure 2, the ring-bound book reversing device 10 comprises a loading section 20 into which the ring-bound book 1 is loaded, a multi-joint robot 30 that performs the reversal operation of the ring-bound book 1, an unloading section 40 from which the ring-bound book 1 is unloaded, and an engaging member 50 used for reversing the ring-bound book 1. The loading section 20 comprises a holding surface 22 consisting of an inclined surface and a locking member 24 provided to protrude upward from the holding surface 22. The locking member 24 is formed in an L-shape, consisting of a first plate-like member 24a extending along the inclined direction (direction A) of the holding surface 22 and a second plate-like member 24b perpendicular to it. When the ring-bound book 1 is loaded from the conveyor 26 onto the holding surface 22, the edges bound by the ring-shaped binder 6 slide and are guided by the first plate-like member 24a, and the edge on the leading end side in the transport direction is locked to the second plate-like member 24b. Multiple air nozzles 28 are arranged above the conveyor 26. The holding surface 22 is formed to be inclined along the second plate-like member 24b, and the ring-bound document 1 is locked to both the first plate-like member 24a and the second plate-like member 24b, and positioned and held on the holding surface 22. In this way, the holding surface 22 is inclined along two directions of the first plate-like member 24a and the second plate-like member 24b with respect to the horizontal plane. Even with factors such as the size, weight, and material of the ring-bound document 1, and friction with the holding surface 22, the corners of the ring-bound document 1 can be reliably set at the reference position, which is the joint between the first plate-like member 24a and the second plate-like member 24b. The articulated robot 30 has a multi-axis (e.g., 4 to 7 axes) structure in which multiple arms 32 are rotatably connected via joints. A chuck 34, consisting of a pair of claws, is rotatably attached to the tip of each arm 32. The operation of the arms 32 and chuck 34 is controlled by a controller (not shown). The discharge section 40 consists of, for example, a belt conveyor. The ring-bound books 1, which have been reversed by the articulated robot 30, are sequentially placed on the conveying surface 42 so that they partially overlap, and then conveyed in the direction indicated by arrow B. The engaging member 50 is supported directly above the discharge section 40. Figure 3 is a perspective view of the discharge section 40 and engaging member 50 shown in Figure 2, viewed in the direction indicated by arrow C. As shown in Figures 2 and 3, the engaging member 50 consists of a cylindrical roller and is positioned between it and the transport surface 42 of the discharge section 40, leaving a gap that allows the ring-bound booklet 1 to pass through. The rotation axis 50a of the engaging member 50 extends horizontally, perpendicular to the transport direction of the discharge section 40, and is rotatably supported by brackets 52 and 54 that rise from both sides of the width direction of the discharge section 40. The engaging member 50 is formed such that its axial length is longer th
