Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus for properly stacking bifold booklets such as bank passbooks, passports, and notebooks.

PRIOR ART The above-mentioned passports, bank passbooks, etc. have a binding form in which the central portion of flat plate paper is machine-stitched and folded in half along the binding line. When sorting bi-fold booklets produced one after another in a bookbinding line into unit numbers, for example, booklets that have been machine-stitched and bi-folded in the previous process are separated between one or more feed rolls. The rolls are passed through to strengthen the folds, and then lowered from the exit of the roll onto a pedestal and stacked flat (vertical stacking), and then transported to the next process after reaching a certain amount of manual stacking.

The problem to be solved by the invention is that it is difficult to give the bifold booklet a perfect fold, and a booklet that is not sufficiently folded tends to spring back immediately after being fed out from the feeding roll. This causes the booklet to open in a ■-shape, and depending on the opening angle, the cover or the paper inside the cover may interfere with the outlet of the delivery roll, causing a problem in which the next booklet to be delivered may intervene in the opened page.

In particular, booklets such as passports and bank passbooks are made of relatively thick paper and have a limited number of pages, so they have a high rate of opening due to the springback, which can easily cause problems. .

Means for Solving the Problems The present invention was provided for the purpose of solving the above-mentioned problems, and as a means for this purpose, the booklets are fed out one after another from the exit of the feeding roll and are stacked flat on a cradle while falling down. In the manual stacking device, the upper presser 341 presses down the cover of the uppermost booklet that has fallen from the feed roll onto the cradle to a level lower than the exit level of the feed roll;
A second upper presser is provided to flatly press the cover of the uppermost booklet pressed down by the upper presser onto the flattened booklet, and the next booklet is placed on top of the booklet that is flattened by the second upper presser. The structure is such that a fixed amount of material is manually loaded, and after the fixed amount of material is manually loaded, the material is transported to the next process using a conveying means.

As described above, the first upper presser presses down the cover of the booklet, which is fed out from the feeding roll and has a V-shaped opening, to a level lower than the level of the exit of the feeding roll, thereby eliminating interference between the cover and the exit of the feeding roll, In addition, the second upper presser presses the cover pressed down to the above-mentioned non-interference level into the flattened booklet to flatten it, and after the first upper presser returns to the standby position, it is flattened by the second upper presser. The next booklet is fed out on top of the stacked booklet.

As a result of the above, when the booklets are fed out one after another from the feeding roll and stacked flat while being lowered, the trouble of the next feeding booklet intervening in the uppermost page opened in a figure 7 shape can be reliably and effectively prevented. Able to properly carry out quantitative discharge of

Embodiments Hereinafter, embodiments of the present invention will be explained based on FIGS. 1 to 6.

Reference numeral 1 indicates a roll for dispensing the booklet 2. The dispensing roll 1 is provided in one stage or in a multi-layered structure, and the booklet 2 is perforated and folded in half at the front upper part of the dispensing roll 1, and then delivered to the dispensing roll 1.

A pedestal 3 is arranged with a certain height on the exit side of the delivery roll 1, and the pedestal 3 is horizontally extended forward from a manual stacking bar for the booklets 2 to form a conveying plate 4.

In other words, in this embodiment, a pedestal 3 is formed at one end of the conveying plate 4, and a chain butcher 6 is provided for endlessly feeding along a groove 5 formed in the longitudinal direction of the conveying plate 4 including the pedestal 3.

The chain butchers 6 rise from the upper surfaces of the pedestal 3 and the conveyor plate 4, are arranged at regular intervals larger than the width of the pedestal 3, and are synchronized with the completion of manual loading of booklets 2 onto the pedestal 3. It moves intermittently and serves as a means for conveying the quantitatively stacked booklet 2A forward from the receiving table 3 while supporting it on the conveying table 4.

One of the bushers 6 is always stopped at the front end of the manual loading part, that is, the cradle 3, and guides the spine of the booklet that is fed out from the feeding roll 1 and falls. On the other hand, a conveyor belt 10 for introducing the booklet between the delivery rolls is hung over the delivery roll 1, and the roll of the belt 10 is made to run and extend perpendicularly to the front end of the pedestal 3 on the exit side of the delivery roll 1. The section is configured to regulate the front edge of the booklet. In other words, the butcher 6 and the belt 10 define a flat stacking part.

Further, side rulers 9 extending in the feeding direction are provided at the edges of the receiving table 3 and the conveying plate 4, so as to guide the feeding while regulating the sides (edges) of the booklets and determining the flat stacking position.

A first upper presser 7 is provided above the pedestal 3, that is, on the exit side of the delivery roll. The first upper presser 7 waits above the exit level of the delivery roll 1, and is placed below the exit level in synchronization with the booklet 2 being delivered from the delivery roll 1 and falling onto the receiving table 3 and being stacked flat. The cover 2a of the booklet 2, which moves downward and opens in a V-shape, is pushed down below the exit level to form a non-interfering state with the roll exit. Synchronize with and return to the top.

Therefore, the 'M1 upper presser 7 moves up and down intermittently between the upper and lower exit levels of the brewing roll 1 at the above-mentioned timing, regardless of whether or not the feeding booklet 2 is opened. The vertical movement is a vertical parallel shift (up and down reciprocating movement) as shown in the figure.
This includes cases in which it is rotated up and down, and cases in which it rotates up and down.

Further, an upper presser 8 is provided which operates from the rear side of the pedestal 3, that is, from the entrance side of the feed roll 1. The second presser foot 8 flatly presses the cover pressed down by the first upper presser 7 together with the booklet into the flat stacked booklet, and supplies the next booklet onto the cover of the flat stacked booklet which is being pressed flat. After receiving the booklet, it exits to the rear of the table (on the feed roll entrance side), and then moves forward again to the next booklet whose cover is being held down by the upper presser 's1, and descends to press this cover flat. .

Therefore, the second upper presser foot 8 always flatly presses the newly fed booklet, that is, the cover that has been pressed down below the level by the first upper presser foot is flatly pressed so that it is completely closed and horizontal, and the next booklet is pressed flatly. It operates at the above timing to prepare for the supply of

Such an operation can be obtained by moving the second flat presser foot 8 in a known box motion.

As the amount of manual booklets increases, the position of the flat presser changes, but such a difference in position can be compensated for by means of elastically supporting and absorbing the second upper presser with a spring.

The structure of the present invention will be described below together with its operation.

As shown in FIG. 1, when the booklet 2 is fed out from the feeding roll 1, dropped, and stacked flat on the flat stacked booklet, the first upper presser 7 is moved to the exit level of the feeding roll 1, as shown in FIG. Cover 2a of booklet 2 descending from a higher level and opening in a V-shape
is pushed down below the exit level of the feed roll 1.

When the first upper presser 7 is pressing down the cover 2a to a position where it does not interfere with the outlet of the feed roll 1, the second upper presser 8 is pressing down the cover 2a
As shown in the figure, it advances above the cover 2a, and then descends as shown in figure M4 and presses down the cover 2a held down by the first upper presser foot until it is completely closed, flattening the supplied booklet 2. Press flat onto the stacked booklet. During this time, the first upper presser 7 is
return to a level higher than the exit level.

As shown in FIG. 5, while the flat presser is held by the second upper presser 8, the next booklet 2' is fed out and properly stacked flat on the uppermost booklet. Thereafter, in the same manner as above, the first upper presser foot 7 is lowered to release the next fed booklet 2°.
The second upper presser 8 retreats from the previous flat-pressing position to the outside of the area, moves forward 2 degrees above the booklet, and descends again to press the next booklet 2'' flat.

In this way, the chain button shear 6 starts moving forward in synchronization with the flat stack reaching the fixed amount, and the button shear 68, which was waiting behind the fixed amount manual stack 2A, receives the rear surface of the fixed amount manual stack 2A. By repeating 0 or more operations of pushing out from the table 3 onto the conveyance table 4 and carrying it out along the conveyance table 4 to the next process, quantitative sorting of the two-folded thin paper sheets successively fed out from the feeding roll is carried out appropriately.

Effects of the Invention As explained above, the present invention arranges the first upper presser and the 'M2 upper presser in the relationship as described above when the booklets that are successively fed out from the feeding roll are divided into units and stacked flat. By operating in a connected manner, the trouble that the topmost booklet opens in a V-shape due to springback and interferes with the outlet of the feed roll, and the next booklet to be fed out interferes with the opening page, is reliably and effectively prevented. However, by carrying out the quantitative manual ordering of booklets properly, problems such as staleness or the need to stop the line due to this trouble can be resolved.
