Description

  In the present invention, a cover and a plurality of intermediate sheets are bound via a binding portion like a bookkeeping mechanism built in an ATM (Automated Teller Machine), a bank window terminal, etc. The present invention relates to a turning mechanism for automatically turning pages of booklets such as passbooks, notes, and books.

  A transaction device such as an ATM arranged as a terminal such as a bank is equipped with a printing device such as a wire dot printer that prints a transaction record on a booklet such as a passbook, and further, a predetermined page is set by turning the booklet before printing. A turning mechanism is attached.

  Conventionally, as a general page turning technique, a method of turning a rubber roller in contact with the top page of a booklet to bend and flipping the top page is widely used, but the frictional force between the rubber roller and the booklet is widely used. Therefore, when the friction coefficient changes due to aging or wear of the rubber roller, there is a problem that a stable page turning operation cannot be maintained.

  As a page turning technique that does not use the frictional force, a method in which the uppermost page is adsorbed is proposed (for example, see Patent Documents 1 and 2).

  According to Patent Document 1, as shown in FIG. 8, the suction roller descends to the end of the booklet to suck the uppermost page (A), and when the booklet is advanced by an appropriate amount, The sucked uppermost page is rolled up about a half turn and separated from the next page (B), and when the adsorbing roller is further lifted to advance the booklet, the sucked uppermost page is flipped in reverse (CE). It has become.

According to Patent Document 2, as shown in FIG. 9, the suction plate descends to suck the cover of the passbook, lifts it to the height of the passbook support guide (ab), and the first roller and the sub roller rotate. The passbook is moved forward and placed on the passbook support guide (c), and the second roller is rotated to advance the passbook so that the cover is turned upside down (de).

  However, the above-described conventional technology has the following problems.

  In the conventional example shown in FIG. 8, one page is turned by the advance of the booklet (D). Therefore, when turning a plurality of pages, it is necessary to return the advanced booklet once and repeat the operations A to E for the pages to be turned. , It takes time to beat.

  Further, in the conventional example of FIG. 9, as in FIG. 8, it is necessary to repeat the operations of a to e for the number of pages that turn, and it takes time for the turning operation, and there is no mechanism for separating the cover from the next page at the time of suction. For this reason, if the next page is also sucked when the cover is lifted, two pages may be placed on the suction support guide and multiple rolls may occur.

  Therefore, in order to solve the above problem, the present invention provides a page turning mechanism that reliably performs the turning operation of one page by scooping up the uppermost page sucked by the sucking portion with the turning lever.

  The first invention is a page turning mechanism for turning a page of a booklet in a transport path, and separates a transport roller for transporting the booklet, an adsorption unit for sucking the top page of the booklet, and a next page of the booklet from the top page. The present invention relates to a page turning mechanism for a booklet, characterized by having a clamping portion to be inserted, and a turning lever inserted between the uppermost page and the next page and scooping up the uppermost page.

  That is, according to the first invention, the suction unit sucks the uppermost page of the booklet, sandwiches the booklet between the clamp unit and the stage and separates the uppermost page from the other pages, and then the turning lever rotates to rotate the uppermost page. In principle, there is a phenomenon in which the rolling operation becomes unstable due to the change of the frictional force of the rolling roller over time, compared to the conventional rolling-up method using the frictional force of the uppermost page. It does not occur, and it is possible to reliably turn only one page over a long period of time.

  According to a second aspect of the present invention, after the uppermost page is sucked and separated from the other pages by the sucking portion, the upper page is lifted up by the turning lever repeatedly, so that the idler arranged coaxially with the turning lever. The present invention relates to a page turning mechanism for a booklet described in the first aspect of the present invention, which holds a plurality of pages scooped up.

  That is, according to the second invention, the booklet can be conveyed after repeatedly placing a plurality of pages on the idler by using the present configuration in which the uppermost page is picked up by the rotating turning lever and placed on the idler. It is possible to turn a plurality of pages at a time by performing the one-time transport operation, and it is possible to significantly reduce the turning time when turning a plurality of pages.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the tip of the turning lever is provided with a turning claw that enables a turning operation in the forward direction or the reverse direction of the uppermost page. It relates to the page turning mechanism of the booklet.

  That is, according to the third aspect of the present invention, it is possible to reliably perform the forward operation or reverse rotation operation of the uppermost page by adopting a structure in which the pawl is extended to both sides at the tip of the pawl lever. Become.

  According to a fourth aspect of the present invention, there is provided the page turning mechanism for booklets according to any one of the first to third aspects, wherein the turning lever includes a cleaning part for cleaning the suction part.

  That is, according to the fourth invention, by attaching a cleaning part such as a brush brush to the side of the turning lever, etc., when the turning lever rotates, paper dust and dust adhering to the suction part are removed each time the page is turned. This makes it possible to perform a stable adsorption operation over a long period of time.

As described above, the present invention produces the following effects.
(1) The top page is picked up by the suction part and separated from the other pages, and then the top page is picked up by the rotating turning lever so that it is turned by the friction force of the conventional turning roller and the top page. In contrast to the raising method, the phenomenon that the turning operation becomes unstable due to the change of the frictional force of the turning roller does not occur in principle, and it is possible to reliably turn only one page over a long period of time.
(2) Also, after the top page is picked up by the pick-up part and separated from other pages, the top page is picked up by the rotating turning lever and placed on the idler. By transporting the booklet after being placed on top, a plurality of pages can be turned at once by a single transport operation of the booklet. In the general suction method shown in the conventional example, the booklet is transported every time one page is turned. Therefore, in order to turn N pages, it is necessary to reciprocate the booklet N times. It becomes possible to shorten to.
(3) Further, by adopting a structure in which the pawl is extended to both sides at the tip of the pawl lever, it is possible to reliably perform the forward motion or reverse traverse motion of the uppermost page.
(4) Furthermore, by attaching a cleaning part such as a brush brush to the side of the turning lever, etc., when the turning lever rotates, paper dust and dust adhering to the suction part can be removed each time the page is turned. A stable page turning mechanism is realized over a long period of time.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a basic configuration of a page turning mechanism according to an embodiment of the present invention. The page turning mechanism includes a conveyance roller (10, 11) that conveys the booklet 2, an adsorption unit 4 that adsorbs the uppermost page 3 of the booklet 2, and a clamp unit 5 that separates the next page 7 of the booklet 2 from the uppermost page 3. And a turning lever 8 that is inserted between the top page 3 and the next page 7 and scoops up the top page 3. The principle will be described below.

  The uppermost page 3 of the booklet 2 is pressed against the suction unit 4 by the pressure plate 1, and the suction unit 4 sucks the uppermost page 3. When the uppermost page 3 is adsorbed by the adsorbing unit 4 and the vicinity of the binding portion of the booklet 2 is sandwiched and rotated by the clamp unit 5 and the stage 6, the pages other than the uppermost page 3 are also rotated. Separated from page 7.

  Thereafter, the turning lever 8 is rotated and inserted into the gap between the top page 3 and the next page 7, and the top page 3 is scooped up. When the turning lever 8 is further rotated, the uppermost page 3 comes off the turning lever 8 and rests on the idler 9. When the booklet 2 is conveyed by rotating the conveying roller A10 and the conveying roller B11, the uppermost page 3 is reversed and the turning operation is completed.

  The front end portion of the turning lever 8 is provided with a turning claw 8 'protruding on both sides of the turning lever 8, so that the forward or backward turning operation of the uppermost page can be reliably performed. In the suction unit 4, the uppermost page 3 is sucked by a vacuum suction method or an electrostatic suction method.

Hereinafter, the main mechanism of the present invention will be described in detail with reference to FIGS. 2 to 5 (part 1) to (part 4) illustrating the operation of the page turning mechanism according to the embodiment of the present invention. In addition, (a)-(j) in a figure represents each state of the booklet turning operation | movement, and it demonstrates according to this state hereafter.
(A) The booklet 2 is sandwiched between a pair of transport rollers A10 and transported to a predetermined turning position. At this time, the stage 6 is slightly rotated clockwise, the pressure plate 1 and the transport roller B11 are moved slightly downward, the gap between the suction portion 4, the pressure plate 1 and the transport roller B11 is widened, and the booklet 2 is entered. Make it easier to do.
(B) When the booklet 2 reaches a predetermined turning position, the rotation of the transport roller A10 is stopped. Thereafter, the pressure plate 1 and the transport roller B11 are raised to press the booklet 2 against the suction unit 4, and the suction unit 4 is operated to suck the uppermost page 3. Then, the clamp part 5 is lowered, and the vicinity of the binding part 12 of the booklet 2 is pressed against the stage 6 and fixed.

The confirmation that the adsorption unit 4 has adsorbed the uppermost page 3 is performed as follows. For example, when the vacuum suction method is applied, if the suction part 4 sucks the uppermost page 3, the air pressure in the suction part 4 decreases (closes to vacuum), and this is detected by the pressure sensor. In addition, when the electrostatic adsorption method is applied, there is a method of detecting transmitted light passing through the booklet by an optical sensor or the like.
(C) The pressure plate 1 and the conveyance roller B11 are lowered, and the stage 6 and the lower conveyance roller A10 and the clamp unit 5 are rotated clockwise with the contact portion between the clamp unit 5 and the uppermost page 3 as the rotation center 13.

  As a result, the booklet 2 is clamped in the vicinity of the binding portion 12 and thus rotates in the clockwise direction together with the rotation of the stage 6 due to the rigidity (strength of the waist) of the paper itself. Further, the top page 3 remains adsorbed by the adsorbing unit 4 and is in a substantially horizontal state, so that it is separated from the next page 7 and subsequent pages (booklet 2).

  Further, when the contact portion between the clamp portion 5 and the uppermost page 3 is set as the rotation center 13, the position and posture of the uppermost page 3 hardly change even when the next page 7 and subsequent pages of the booklet 2 are rotated. The force to peel off in the direction parallel to and perpendicular to the suction surface 4 is small, and the uppermost page 3 is firmly held by the suction portion 4.

Thereafter, the turning lever 8 is rotated clockwise and inserted between the uppermost page 3 and the next page 7.
(D) The suction portion 4 is rotated clockwise by a certain angle, and the uppermost page 3 is bent upward. This is a preparatory operation for the turning lever 8 to reliably lift the uppermost page 3 upward in the next state (e). Further, the turning lever 8 continues to rotate.
(E) When the turning lever 8 comes into contact with the tip of the uppermost page 3, the suction of the suction part 4 is released, and the suction part 4 is returned to the initial position. Further, the turn lever 8 rotates to scoop up the uppermost page 3.
(F) The turning lever 8 continues to rotate and continues to lift up the top page 3.
(G) Further, when the turning lever 8 is rotated, the uppermost page 3 is detached from the turning lever 8 and is placed on the idler 9.
(H) Using the contact portion between the clamp portion 5 and the uppermost page 3 as the rotation center 13, the stage 6 and the lower transport roller A10 and the clamp portion 5 are rotated counterclockwise to return to the initial position in the state (b). Further, the pressure plate 1 and the conveying roller B11 are also raised and returned to the initial position in the state (b).
(I) The clamp part 5 is raised and the pressing of the booklet 2 to the stage 6 is released. When the conveyance roller A10 and the conveyance roller B11 are rotated to convey the booklet 2 to the right, the uppermost page 3 placed on the idler 9 rotates counterclockwise with the binding portion 12 as a fulcrum.
(J) When the conveyance roller A10, the conveyance roller B11, and the conveyance roller C14 are rotated to convey the booklet 2 further to the right, the uppermost page 3 is reversed and the page turning operation is completed.

  Note that the state of each part of the mechanism in (h) when the top page 3 is placed on the idler 9 is the same as in the initial state (b). When the procedures (b) to (h) are repeated again from the state (h), the next page 7 is also placed on the idler 9 in addition to the top page 3. When (i) and (j) are executed and the booklet 2 is conveyed, two pages of the top page 3 and the next page 7 are read.

  Similarly, if the steps (b) to (h) are executed N times and then (i) and (j) are executed, it is possible to turn the booklet 2 for N pages with one transport. Become.

  In this embodiment, as shown in (j), the booklet 2 has a symmetrical structure around the suction portion 4, the turning lever 8, the idler 9 and the transport roller B11. The booklet 2 is transported from the right by the transport roller C14 in the left direction, and the right half of the diagram (j) is used to turn the rolls (a) to (i) (however, the diagrams (a) to (i)). If the booklet 2 is conveyed to the left in (j), the turning operation for N pages can be performed.

  In this embodiment, the stage 6 and the lower conveying roller A10 and the clamp part 5 are rotated clockwise with the contact part between the clamp part 5 and the uppermost page 3 as the rotation center 13 (c). 6 and the lower conveying roller A10 and the clamp part 5 are not rotated, but the suction part 4, the turning lever 8 and the idler 9 are rotated counterclockwise in an arc shape around the rotation center 13, and the uppermost page 3 Can be separated from the next page 7.

FIG. 6 shows a control flow of the turning mechanism according to the embodiment of the present invention. This control flow represents each state (a) to (j) of the page turning operation described in FIG. 5 as a flowchart.
