  By the way, as a bookbinding method, bookbinding methods using various types of binding methods such as saddle stitching, perfect binding, and flat stitching are known. Among these, the bookbinding method called “flat binding” has conventionally used a region of a predetermined width from the side edge as a “binding margin” on any one side of the stacked sheets, and the cover side in this “binding margin” This means that the wire (or stapler needle) is passed through from the back to the back cover side, but recently, the “binding margin” of each sheet (each sheet that becomes the “back side” when bound) A bookbinding method in which a booklet is manufactured by applying an adhesive to a predetermined width region on one side edge of a paper sheet and superimposing them is also being implemented. In the industry, it is recognized as an aspect of “flat stitching”.

  Even in flat stitch binding using an adhesive as described above, each sheet 51 can be forcibly dropped into the stacking device using the impeller 52 so that the time required for the bookbinding process can be shortened. As shown in FIG. 6, when the adhesive G is applied to the binding margin of each sheet 51, the side edge 51 a of each sheet 51 is applied to each fin of the rotating impeller 52. On the other hand, it may be temporarily stuck via the adhesive G, and it may not be possible to suitably perform the operation of dropping each sheet 51.

The present invention has been made to solve the above-described problem, and the operation of dropping the sheet into the stacking apparatus without contact between the adhesive applied to each sheet and the impeller. An object of the present invention is to provide a bookbinding apparatus and a bookbinding method capable of smoothly performing the above.

A bookbinding apparatus according to the present invention is configured to transport a sheet in a horizontal direction by a transporting means, and a pair of impellers are arranged in front of the transporting direction of the transporting means, and each axis is defined as a sheet transporting direction. When rotating around the axis so that they are parallel to each other, the transported sheets are placed opposite each other so that they can be beaten by the impeller, and the sheets are directed from above to below. With each impeller rotated in the direction that can be tapped, the sheet is fed to the space between the two impellers, thereby changing the transport direction of each sheet from horizontal to vertical. A plurality of fins configured to forcibly drop the sheets into the stacking device below the impeller, and the impeller is formed so as to protrude radially from the peripheral surface of the body portion at a predetermined angle. And the outer edge of those fins A tapping means constituted by a flap configured to protrude with a predetermined width toward the rotation direction, or a plurality of fins formed to protrude outward from the circumferential surface of the trunk portion A hitting means having a curved shape centered on a virtual axis parallel to the axis, or a shape bent along a virtual straight line parallel to the rotation axis, or both end portions outward from the circumferential surface of the body portion A sheet having a hitting means composed of a U-shaped rod-shaped member fixed so as to protrude toward the outside and held at a position where the intermediate portion is spaced outward from the circumferential surface of the body portion In the case where an adhesive is applied to the binding margin along the side edge of the leaf paper, it is characterized in that the inner region of the adhesive can be beaten .

Further, the bookbinding method according to the present invention includes a pair of sheets in which adhesive is applied to the binding margin along the side edge, which is transported in the horizontal direction by the transporting means, and is opposed to the front in the transport direction of the transporting means. The impeller is rotated in a predetermined direction, and the sheet fed to the space between the two impellers is struck from the upper side to the lower side by the impeller so that the transport direction of each sheet is horizontal. In the method of changing the direction from the vertical direction to forcing the sheets into the stacking device below the impeller to perform bookbinding, the impeller is radially spaced from the peripheral surface of the body portion at a predetermined angle. A tapping means constituted by a plurality of fins formed so as to protrude and a flap configured to protrude with a predetermined width from the outer edge portion of the fins toward the rotation direction, or the circumference of the trunk portion Projecting outward from the surface A plurality of fins formed as described above are shaped into a circular arc centered on a virtual axis parallel to the rotation axis, or a hitting means having a shape bent along a virtual straight line parallel to the rotation axis, or Both ends are fixed so as to protrude outward from the circumferential surface of the barrel, and the middle portion is formed by a U-shaped rod-shaped member held at a position away from the circumferential surface of the barrel. It has a hitting means, and taps the area inside the adhesive applied to the binding margin along the side edge of the transported sheet to drop the sheet into the stacking device. It is said.

In the bookbinding apparatus according to the present invention, when performing forced dropping work respective sheet to the stacking device, even if the adhesive is applied to the binding margin of respective sheet, each sheet The problem that the adhesive applied to the leaf paper comes into contact with each fin of the impeller and eventually the binding margin of the sheet is temporarily stuck to the impeller via the adhesive is preferably avoided. be able to.

Embodiments of a “bookbinding apparatus” according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a front view of an impeller 1 used in the bookbinding apparatus of the present invention in the first embodiment. As shown in the figure, the impeller 1 includes a cylindrical body 2, four fins 3, and a flap 4 (striking means). Of these, the fins 3 are formed so as to protrude radially from the peripheral surface of the body 2 at an angle of 90 °, and the flaps 4 rotate in the rotational direction R (blade from the outer edge of each fin 3. It is attached so as to protrude with a predetermined width in the rotation direction of the car 1.

  In the impeller 1, the amount of protrusion of the fin 3 (height dimension from the circumferential surface of the body portion 2 to the outer edge portion) and the amount of protrusion of the flap 4 are the tip of the flap 4 when the impeller 1 rotates. 4a exceeds the adhesive G applied to the binding margin along the side edges 51a (or one of the side edges 51a) of the transported sheet 51 (see FIGS. 1 and 6). , It is designed to touch only the inner region (tap only the inner region).

  That is, in this embodiment, the hitting means composed of the fins 3 and the flaps 4 is more than the adhesive G applied to the side edge 51a of the sheet 51 being transferred when the impeller 1 rotates. Since the inner region (region close to the center of the sheet) is configured to be beaten, when the work of dropping the sheet 51 into the stacking apparatus by rotating the impeller 1 is performed, the sheet The problem that the side edge 51a of the paper 51 temporarily sticks to the fins 4 of the rotating impeller 1 via the adhesive G can be preferably avoided.

  In the present embodiment, the flaps 4 attached to the fins 3 are continuous over the entire length of the impeller 1 as shown in FIG. 2, but the flaps 4 are not necessarily continuous. As long as it is configured to be able to strike only the area inside the adhesive G applied to the binding margin of the sheet 51 when the impeller 1 is rotated, any shape is possible. Alternatively, it may have a structure. For example, as shown in FIG. 3, the flaps 4 may be attached to the fins 3 so as to be intermittently juxtaposed in a comb shape.

  Further, the hitting means does not have to be configured by combining a plurality of members such as the fins 3 and the flaps 4 as in the first embodiment. For example, as shown in FIG. Each fin 3 formed so as to protrude outward from the peripheral surface of the portion 2 is curved in an arc shape around a virtual axis parallel to the rotation axis of the impeller 1 or the rotation of the impeller 1 By bending along an imaginary straight line parallel to the axis, the adhesive G applied to the binding margin along the side edge 51a of the transported sheet 51 is passed to an area inside it. It can also be configured to contact only.

  Further, the hitting means does not have to be constituted by plate-like members (fins 3 and flaps 4) as in the first embodiment, but as shown in FIG. The “U” -shaped (or “L” -shaped) rod-shaped member 5 fixed so as to protrude outward from the rod serves as a hitting means, and an intermediate portion of this rod-shaped member 5 (the rotation of the impeller 1) The portion extending in parallel with the axis) may be configured to strike only the region inside the adhesive G applied to the binding margin along the side edge 51a of the transported sheet 51. it can.
