With the automatic vertical aligning device for the signatures, the 22nd signatures are sequentially fed from the bottom in the form of wraps and the lower stacking wraps are vertically aligned. It is very important to manually take out a specified number of sheets from the above, and to re-sort them into flat stacks on another aligning stand, and to manually transfer the aligned stacks to another strapping device for strapping work. Since it is a labor-intensive and labor-intensive work process, the worker constantly monitors the number of vertical alignments and extracts a fixed amount from the vertical alignment group → realigns the flats on another stand → Since it is necessary to repeat the sequence of carrying the stacking device for stacking paper → strapping, it requires a great deal of labor and work time and is extremely inefficient in work efficiency, and it is different from the vertical alignment device of the preceding invention. Obi strapping device To high equipment cost is applied over a period of two devices and another aligned stand fixtures of equipment, large installation takes the space is a very uneconomical strapping cost and correlated with the manual work is high. In addition, as a string tying and binding mechanism for signatures,
There is a prior invention of Japanese Examined Patent Publication No. Sho 60-9919 (a paper folding machine connected with a signature binding mechanism) relating to the same person as above, but it relates to a large paper folding machine and a large number of bookbinding signature groups are vertically aligned. This is a device for bundling, and it is not suitable for flat stack paper wrapping, which is targeted for small-sized subdivision such as this kind of distribution document, so the flat stack of subdivision distribution document → There was a strong demand for the appearance of a simple, labor-saving, high-speed workable, and economical automatic device that can be used automatically and continuously without the need for human labor. SUMMARY OF THE INVENTION The present invention is a folding document of this kind in view of the inconvenience and inconvenience of the above-mentioned conventional uneconomical separate apparatus and equipment which are extremely inconvenient for human labor. A stack of vertically stacked stacks for stacking the stacked wrap paper from bottom to bottom is automatically moved up and down from the stacking part of the stacker in the vertical path, and the flat stack paper is automatically converted and sent to the horizontal path transport mechanism to perform subdivision. Providing an automatic unit wrapping device, eliminating the above-mentioned manual labor, realizing labor saving and high speed automation from the small flat stack of the document to the wrapping, and its excellent work efficiency and excellent demand With a convenient and high-speed fully automatic unit device, multiple individual devices and equipment are unnecessary, equipment costs are reduced, and installation space is reduced.
In addition, the purpose is to surely reduce the cost of subdividing this kind of distribution document. A stacker of a belt conveyor having a plurality of driving belts spaced apart from each other and a rear portion thereof serving as a flat stack portion for bottom-lapping lap paper feeding is provided as a vertical path, and each belt is placed laterally below the stack portion. A laterally feeding laterally feeding roller group, which is arranged in parallel in order, is electrically moved up and down next to the belt, and a laterally feeding conversion roller mechanism provided so as to laterally feed the flat stack paper by the roller group that is elevated above the belt, and the stacking section. On one side, the side roller is connected to the ascending roller in parallel with the parallel roller group, and the automatic belt hooking mechanism is installed at the end of the side path. On the portion, a contact guide plate that is provided at right angles to the transport path by straddling each belt and roller, and a roller group rotation provided on the back side of the plate. It is a unit forming means for providing a driving belt mechanism for rolling power and a sensor for electrically switching the conversion roller mechanism up and down by a paper feed detection operation near the front of the stack portion. [Operation] When a predetermined number of under-lap wrap origami sheets are fed by a stacker in a vertical path and folds sequentially hit a contact guide plate provided at a right angle on the stack section at the rear, stacking is performed. A predetermined number of flat stack sheets are automatically formed on the set in order from the bottom. The roller group of the transverse feed conversion roller mechanism is electrically lowered while the wrap paper feed sensor is being detected. When the final lap paper passes through the sensor and is no longer detected, the roller group is switched up to cause a flat stack. The roller group rises to a position higher than the belt at the end point in time, and the roller rise is maintained until the next sheet feeding detection occurs, and the ascending roller is the parallel roller group of the lateral transfer roller mechanism. When the belt comes into contact with the belt, it will rotate horizontally, and the stack paper will be placed on the rollers of the flat stack, levitated on the belt, and will be automatically traverse-converted from the vertical path to the horizontal path, and will be fed laterally. The stack paper is connected to the lifting roller and is continuously installed next to the stack section. It is automatically band hanging in the structure. The conversion lateral feed of the stack paper is performed by a guide along the contact guide plate, and when the next paper feeding front end is detected by the sensor at the lateral feed conversion timing of the stack paper,
The ascending roller stands by below the stack, so that the next flat stack process can be performed without any problems, and at the end of the stack, the horizontal feed roller rises → lateral feed → next sequential feed → horizontal feed roller lower → stack end → The traverse roller ascending path automatically repeats, and the automatic belting from the lateral transportation of the laterally fed permuted stack paper continues automatically. The embodiments of the present invention will be described in detail with reference to the accompanying drawings. Contacting the other side of the well-known sandwich conveyor mechanism K, which sandwiches and feeds a proper stack of folding documents (hereinafter referred to as origami) for direct mail, catalogs, and various other types of advertising, etc. The drive belts 1 of the strips are installed at equal intervals, and a well-known press roller mechanism P for press-feeding origami paper is provided. The rear portion 2 is a flat stack portion for stacking lap paper feeding, and the rear portion 2 is inclined downward. The stacker A of the belt conveyor designed as described above is used as a vertical path, and each side of each group of the belts 1 on the conveyor plate surface 3 of the stack section is aligned in the belt direction and corresponds to the length of the stack section. Within the range, a group of narrow holes 5 into which the lateral feed rollers 4 that are laterally rotated with respect to the direct drive of the belt 1 are loosely fitted are provided. As shown in FIGS. 4 and 5, the above-mentioned roller 4 group, which is loosely fitted into each of the narrow hole groups 5, is arranged to move up and down the electric rods 7, 6'of the opposed electric devices 6, 6 '. 7 ′ is attached to the bottom portion and is freely rotated on the upper side of the support case body 8 which is electrically moved up and down through a bearing or the like (not shown). When the case body 8 is electrically raised, the lateral feed roller 4 is raised. The upper part of the group passes through the group of narrow holes 5 and is projected to a position higher than the belt 1 (see FIGS. 1, 2 and 4), and conversely, when the case moves down, the group of rollers 4 becomes narrow holes. The horizontal feed conversion roller mechanism B, which is positioned below the fifth group (see FIGS. 3 and 5),
The stacker A is mounted on the lower part of the stack part of the rear part 2. As an example, the stacker A is preferably designed so that the rear portion 2 is inclined downward as illustrated.
A flat design with no inclination is acceptable. C is a lateral transfer roller mechanism for a large number of parallel rollers 9, which is a stacker A group of rollers 4 rising laterally with respect to the side of the rear portion 2 of the stacker A in the rotational direction of the rollers 4. The parallel rollers 9 are aligned at the same height as, and are connected and connected in a communication form. The automatic strapping mechanism D is connected to the end of the mechanism C. Reference numeral 11 designates a long contact guide plate which is folded under the wrapping paper feed to form a flat stack from the bottom, and the stack paper is crease-guided and fed across the stacker A. The rollers 4, 9 which are arranged in parallel to the tip of the transport roller mechanism C on the lateral path.
On the rear part of the group, the belt and the roller group are laid across at a groove 10 formed in the lower side, and the belt and the roller group are installed at a right angle. Therefore, the plate 11 is installed in the stacker A
When the rear part 2 of the is inclined downward and the lateral conveyance path is an inclined road,
It is a form that inclines backward at a right angle corresponding to the inclination, and is straight upright in the case of non-inclined flat. Even if the flat stack paper is in the open fold state, the stack is tilted in the fold direction, so there is no anxiety about stacking failure and uneven fold stacking. The tilted flat stack paper is normally guided laterally while the fold side is pressed against the plate 11, so it is preferable to install the tilted flat stack paper, but even when the flat stack paper is upright on a flat road, the press roller mechanism P is used. With a strong fold press stack, opening of folds will be blocked and a normal stack and its transverse feed will be possible. Next, the rear upper portion of the parallel roller group 9 of the conveying roller mechanism C is brought into belt contact with the rear side portion of the contact guide plate 11 in accordance with the length of the plate 11 so that the roller group 9 is formed. A drive belt mechanism E driven by a motor M that causes the rotation of the transverse feed rollers 4 of the conversion roller mechanism B to be brought into contact with the belt and causes rotation only when the group of transverse feed rollers 4 of the conversion roller mechanism B is raised is installed. A sensor 12 for electrically switching the conversion roller mechanism B up and down by a paper feed detection action is provided near the front of the stack portion of the rear portion 2.
By installing from the support frame 13 via the arm 14, as described above, the stacker A of the flat stack which is the vertical path, the lateral feed conversion roller mechanism B, the lateral transport roller mechanism C, and the automatic banding mechanism. D, the drive belt mechanism E, the contact guide plate 11 and the sensor 12 constitute a unit. The vertical moving means of the lateral feed conversion roller mechanism B is preferably the above-mentioned electric rods 7 and 7 ', but instead, an appropriate vertical moving system relating to hydraulic pressure, a rack, a screw rod or the like. Means can be employed. While the lap feeding is being detected, the lateral feed roller group 4 moves downward, the sensor 12 does not contact the belt, is in a non-rotating state, and is in an ascending standby state. When this happens, the group of rollers 4 is raised to a position higher than the belt and is rotated by contact with the belt, so that the flat stack paper is placed on the raising roller and floats on the belt to perform automatic transverse feed conversion. It is a switching sensor. Incidentally, as an example of an additional embodiment of the drive belt mechanism E which serves as rotational power for each of the rollers 4, 9 having a lateral path structure, the rollers 4, 4, 9 9 It is desirable to design a series of belts that can work together, but as another example, the rollers 4, 9
It is also possible to adopt a design change to two separate belt configurations (not shown) for each group. In the case of this divided belt mechanism, each belt driving speed is set to a low speed on the side of the lateral feed roller 4,
It is possible to make the parallel roller 9 side have a high speed at a different speed. The present invention relates to the above unit constituting means,
The operation will be described. When the stacking origami group of lower-layered wraps with the crease at the delivery discharge from the paper folding machine as a first is counted in a constant number by the counter and fed to the stacker A for each predetermined number of small sheets, Each of the wrap groups is a conveyer K
Is fed to the flat stack portion of the rear portion 2, the folds sequentially hit the guide plate 11, and a predetermined number of normal flat stack sheets are automatically formed on the stack portion from the bottom. The delivery of the wrap group to the stacker A may be carried out in a plurality of rows in parallel. In this case, the stacks are arranged in several rows in parallel with the plate 11. In the horizontal feed of, a large number of sorting orders will be applied. Thus, the leading edge of the lap paper feed is the sensor 12
When it is detected by, the electric rods 7, 7'of the electric devices 6, 6'opposed to the lateral feed conversion roller mechanism B are pulled downward and descend, and the support case body 8 attached thereto is driven. Since the lateral feed roller group 4 descends below the narrow hole group 5, the lap paper feed passes above the roller group 4 to form a flat stack at the stack portion. Then, when the last part of the lap paper feed is not detected, the electric devices 6 and 6'are switched, the electric rods 7 and 7'are moved upward, and the case body 8 is driven, and the timing is adjusted at the end time of the stacking. The group of rollers 4 in the standby state moves up below the stack portion, and the upper portion of the rollers protrudes from the group of narrow holes 5 to drive belt 1.
It will be at a higher position than the above, and the stack paper will be lifted from the belt and placed on the lift roller. When the raised group of rollers 4 is in contact with the parallel roller group 9 of the lateral feed transport roller mechanism C at the same height, the drive belt mechanism is installed on the back side of the plate 11 and constantly rotates the parallel roller group 9. The rear upper part of the rising roller group comes into contact with the rotating belt of E, and the parallel roller 9
Lateral rotation is interlocked with the group, whereby the stack paper placed on the lifting roller is laterally fed on the stacker A of the flat stack, and is automatically laterally fed to the mechanism C on the lateral path. At C, it is conveyed to the automatic strapping mechanism D under the guide feeding along the plate 11, and the automatic strapping is completed. When the next paper feed edge is detected by the sensor at the horizontal feed timing of the stack paper ascending roller, the electric devices 6 and 6'are switched as described above, and the ascending roller 4 group is moved down. It becomes a stand-by state under the stack part, and the continuous stacking process of the next order without any hindrance will be performed, and at the end of the stack, the horizontal feed roller rises → horizontal feed → next sequential feed → horizontal feed roller lower movement → stack end → The traverse roller ascending path is automatically repeated, and the automatic belting from the lateral transportation of the laterally fed and stacked stack paper is continuously performed at high speed. Therefore, according to the present invention, by the above unit configuration and the electric up / down switching braking from below the transverse feed conversion roller mechanism B, the fully automatic banding work of the flat stack group of small-sized origami sheets linked to the delivery of the paper folding machine can be performed. it can. As described above, the present invention provides: It is convenient to realize the complete labor-saving automation from the small flat stack of this type of origami paper to the banding at high speed with the one fully automatic unit device. 2. Since only one unit is required, the equipment cost is much lower than the conventional multiple equipment and equipment required, and the installation is space-saving, which is very economical and demanding. Excel. 3. This device is a mechanism for performing lateral feed conversion of stack paper by vertically driving the lateral feed rollers 4 group from below toward the stacking portion of the stacker A, and is a connecting unit of each mechanism, so the overall mechanism is It is easy and economical because it can be provided at a low production cost. 4. Experimentally, the work efficiency of subdivision with origami paper of this kind is only about 7,000 sheets / hour in the case of the conventional manual work, but this device is capable of 48,000 sheets / hour, which is outstanding. The obi belt can be mass-produced at low cost, and the economy is very high. There is a great effect such as.
