DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for feeding a signature printed matter, such as a newspaper, from which a set of signature printed matter is taken out one by one and supplied.

[0002]

2. Description of the Related Art Newspapers delivered to homes and workplaces contain leaflets or reprinted newspapers.
A large number of personnel must be secured when performing the folding work such as a leaflet by hand. In addition, about 20 copies of the newsprint that hit the seam of the web are discharged from the web offset press every few minutes, but even when the good paper in the newsprint is transported directly to the shipping place without being poured into the counter stacker. A large number of personnel must be secured in the post process of the shipping operation. Furthermore, in the process of binding a magazine or the like, a collation operation is required in which a plurality of signatures are printed one on top of another, and similar problems also occur when the collation operation is performed manually. . In other words, for example, in the case of a 240-page magazine, it is necessary to perform an operation of overlapping 15 copies of a 16-page signature printed matter.

[0003] Therefore, devices that can automatically perform these operations are required, but these devices first take out and supply the signature prints one by one from a bundle of signatures such as newspapers. Must be included. As this apparatus, a device is used in which a sucker is pressed from above a stack of signature books printed in advance to turn over one copy of the signature book, and this is sandwiched between a pair of claws and taken out. Also, in the bookbinding process, a method is used in which a suction cup is pressed from under a bundle of previously stacked signature prints to turn over one copy of the signature print, and the copy is taken out by sandwiching it with a pair of claws.

However, if a suction cup is pressed from above a bundle of signatures printed matter, it is not possible to replenish the signatures printed material at any time, so the next bundle must be replenished after the entire bundle has been taken out. Work efficiency is poor. Further, in order to keep the top position constant, a lift-up mechanism for gradually lifting the bundle of signatures printed matter must be adopted, and a large driving force is required. Since the number of pages of the target origami printed matter may be significantly different from 2 to 48 pages, the lift-up mechanism must be provided with a speed adjusting function, which complicates the structure. Furthermore, when the signatures are stacked, the folding side (the take-out side) is extremely crooked and curved, which hinders the take-out operation. Also, in the case of pressing the suction cup from under the signature printed matter, it can be said that it is superior to the above-described device in that it can be replenished at any time and the folding side is not extremely deformed, but while receiving the total weight of the stacked bundle A large driving force is still required to pull out the bottom signature printed matter by dragging it out, and when used for thin signature printed matter such as a leaflet bundle, the signature printed matter may be cut during removal. . To avoid this, if the amount of stacking is reduced, the replenishment operation must be repeated frequently. Further, since the replenishment position must be at a considerably high position, there is a problem in replenishment work efficiency. Further, with respect to a leaf bundle A as shown in FIG. 9, the end B of the printed matter exposed on the sandwiching side is separated when sucked by the suction cup, and this end B is sandwiched by the claws. I can't grasp it for sure.

[0005] In contrast to the above two types of apparatus which have these drawbacks, the supply apparatus described in Japanese Patent Application Laid-Open No. 4-169422 takes out one copy at a time in the direction of gravity in a state where signature prints are stacked. Therefore, it is an epoch-making device which has no drawbacks of the prior art, has a simple structure, can be implemented with a small driving force, and can be used to supply a bundle of a plurality of signatures such as a leaflet bundle. .

[0006]

By the way, Japanese Patent Application Laid-Open No.
The supply device described in Japanese Patent Application Laid-Open No. 169422 is for taking out a signature printed matter by a falling method using gravity.

Therefore, while the structure of the apparatus is extremely simple, it is necessary to set the processing speed for taking out the signatures in consideration of the drop time. In addition, if the signature printed matter is thin and light, a drop trouble may occur.

Accordingly, an object of the present invention is to provide an apparatus for feeding a signature printed matter capable of reliably performing a takeout process at high speed without complicating the configuration of the apparatus.

[0009]

According to the present invention, there is provided an apparatus for feeding a signature printed matter according to the present invention, wherein the folded part of the signature printed matter, such as newsprint, is stacked upright with the folded side facing down to a take-out position. An apparatus for feeding a signature printed matter, which feeds the signature printed matter one copy at a time, comprising a stopper mechanism for stacking the signature printed matter, and a forward feed for sequentially forward feeding the stacked signature printed matter. An apparatus, a suction cup for turning over one copy of the signature printed matter at the take-out position, and a separating plate with a free roller that rises and enters the rear side of the folded signature printed matter,
A drive roller that sandwiches the signature printed matter with the free roller and that is rotated by a motor and pulls out the signature printed matter downward, wherein the drive roller is configured such that the sorting plate with the free roller is raised and the signature printed matter is raised. When it enters the rear side, it moves to the sorting plate side with the free roller, and sandwiches the signature printed matter with the free roller.

[0010] It is preferable that the stopper mechanism and the forward feed device are slightly inclined to the front lower side so that the stacked folded prints do not fall backward.

When the width regulating guides are provided on both the left and right sides, it is effective that the width regulating guide is configured to advance each signature printed matter forward when necessary, in combination with the forward feeder.

The lower side of the front face of the signature printed matter approaching the take-out position is slightly pushed back using the push-back member at the operation timing of sucking with the suction cup, and the lower side is reduced so as to reduce the degree of adhesion between the signature printed matters. Or send the wind from the side,
It is also effective to prevent two or more parts from being taken out at the same time.

[0013]

The signature printed matter is sandwiched between the free roller and the drive roller, and the signature printed matter is pulled out by the rotation of the drive roller, so that the signature printed matter can be taken out at high speed and reliably.
Moreover, since the free roller is attached to the sorting plate, there is no need to provide a separate mechanism for moving the free roller.
In addition, since the drive roller is moved to the sorting plate side with the free roller to sandwich the signature print, the drive roller and the free roller sandwich the signature print with sufficient force for any thickness of the signature print. It can be configured to attach.

If the width regulating guide has a forward feed function,
Even if the signature printed matter is thick, it can be accurately and reliably moved.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a side view of a newsprint feeder provided with a newsprint feeder which is a feeder for a signature printed matter according to the present invention.

The newspaper feeder 1 has a belt wheel device 3 on the lower side.
(Forward feeder), and the newspaper C is placed on the belt wheel device 3 and is sequentially and intermittently advanced from the right inlet to the left outlet in the drawing. The newspaper C is loaded in such a manner that the folded side (in this embodiment, the folded side of the quadrant in the second fold) is turned down, and an appropriate number of copies are stacked so that the feeding direction is perpendicular to the paper surface. Moved to.

Width regulation guides 5 are provided on both left and right sides of the newspaper feeder 1, and the interval between the width regulation guides 5 is set slightly smaller than the width of the folded newspaper C. Therefore, the newspaper C transferred to the intake port moves to the take-out position with a strong waist for standing to bend forward (to the left in the drawing) when viewed from above. Also,
The belt pulley device 3 is slightly inclined forward and downward (lower left in the figure) so that the stacked newspaper C does not fall backward (right in the figure).

A sorting plate 7 is arranged below the take-out position of the newspaper feeder 1, and the sorting plate 7 is provided together with a stopper plate 9 (a stopper mechanism) provided on the upper side, and the newspaper C sent thereto. Damme. When the partitioning plate 7 is lowered to release the damming state, the suction cup 11 sucks the lower front side of the newspaper C at the tip and turns only the newspaper C1 at the tip. When the separating plate 7 is inclined upward into the gap formed between the leading end newspaper C and the second newspaper C, the driving roller 13 is provided on the separating plate 7. The paper 15 at the leading end is interposed between the paper 15 and the paper 15 and is pulled downward.

The newspaper C that has been pulled out of the newspaper feeder 1 and dropped is guided by the guide 17 and received by the stacking device 19, moves at a low speed, and is shifted and overlapped at a constant pitch to a counter stacker (not shown). It is poured.

FIG. 2 is a side view showing details of the newspaper feeder 1. As shown in FIG.

A swing bar 25 is attached to the mounting member 21 so as to swing by the operation of the link 23, and the suction cup 11 is provided at a lower end of the swing bar 25.

An oscillating plate 29 is attached to the mounting member 27, and the oscillating plate 29 rotatably supports a rotating shaft 31 to which the driving roller 13 is fixed. The swinging plate 29 is provided with a lever 33. When the lever 33 is pressed down by a pressing member 35, the swinging plate 29, that is, the drive roller 13 is moved to the left side in the drawing. However, if the pressing member 35 is raised, the swinging plate 29 and therefore the drive roller 13 move to the right side in the drawing by the spring force of the tension coil spring 39 attached to the supporting beam 37. And a free roll attached to a newsprint guide 41 formed on the sorting plate 7.
And only the newspaper C1 is sandwiched between the paper 15 and the paper 15. The driving roller 13 is rotated by a motor (not shown) via belts 43 and 45 in the direction of the arrow.

The stopper plate 9 is provided with a roller 47 for facilitating pulling out of the newspaper C.

FIG. 3 is a front view showing details of the newspaper feeder 1. As shown in FIG.

One end of a swing arm 49, 51 is rotatably attached to the lower side of both ends of the separating plate 7, and the other end of the swing arm 49, 51 is rotatably mounted on the support beam 37. Installed. Each swing arm 49, 51
Are provided with links 53 and 55, and the links 53 and 55 move up and down ahead of the link 53 while maintaining a phase difference of about 90 degrees. The forward feed of the newspaper C is performed when the sorting plate 7 is protruding above the belt wheel device 3,
Newspaper C is prevented from falling.

In the figure, reference numeral 57 denotes a shock absorber (the shock absorber on the right side in the figure is shown in FIG. 2).

FIG. 4 is a plan view schematically showing the belt wheel device 3.

The belt wheel device 3 includes a primary feed belt device 59.
When the newsprint confirmation sensor 63 detects the newsprint C which has been fed forward by the intermittent operation of the primary feed belt device 59, the primary feed belt device 59 stops operating. Therefore, newspaper C
Is the rear bundle that stops near the tip of the width regulation guide 5,
The secondary feed belt device 61 is divided into a front bundle that is fed forward by intermittent operation. Then, the front bundle is taken out and the remaining amount is reduced, and the newspaper confirmation sensor 63 detects the newspaper C
Is not confirmed, the primary feed belt device 59 operates again to take out the newspaper C in the direction of the take-out position.

Since the speed of the secondary feed belt device 61 is increased with respect to the speed of the primary feed belt device 59, the newspaper C, which has a strong waist for standing forward and standing, can be used for the width regulating guide 5. When it comes off, it reaches the removal position in a stretched state.

FIG. 5 is a perspective view showing details of the width regulating guide 5. As shown in FIG.

The width regulating guide 5 has feed belts 63 on the upper side and the lower side, respectively. The feed belts 63 are driven by a drive belt 65 in synchronization with the primary feed belt device 59 to feed the newspaper C forward. Operates intermittently.

It is also possible to use a screw instead of the feed belt, and feed the newspaper C forward by rotating the screw.

FIGS. 6 to 8 are diagrams for explaining the operation process of the newspaper feeder 1. FIG.

When the separating plate 7 moves downward, the swing bar
25 swings rightward in the figure, and the suction cup 11 sucks the lower front side of the newspaper C at the tip (FIG. 6). At this time, air is sent from the lower side or the lateral side to the newspaper C in order to reduce the degree of adhesion between the newspapers C, but the suction cup 11 slightly pushes the newspaper C at the take-out position as a push-back member. , And reliably prevent two or more copies of the newspaper C from being turned at the same time. Next, swing bar-2
5 swings to the left in the figure, and the suction cup 11 turns over only the newspaper C at the tip, and the separating plate 7 rises into the gap between the newspaper C at the tip and the second newspaper C (FIG. 7). Thereafter, the swinging plate 29 swings to the right in the drawing, and the driving roller 13 rotating in the direction of the arrow causes the newspaper C at the leading end to free roll 1.
5 and pull out downward (FIG. 8).

[0037]

As described above, when the signature-printed material supply apparatus of the present invention is used, the signature-printed material is forcibly pulled down, so that high-speed and reliable take-out processing can be expected.

Further, since the free roller is attached to the sorting plate, and the driving roller is moved toward the sorting plate with the free roller to sandwich the signature printed matter,
With a simple configuration, it is possible to reliably pull out printed signatures having different thicknesses.

If a width regulating guide is provided and the width regulating guide is provided with a forward feed function, the advance feeding of the signature printed matter can be performed accurately and reliably, so that the supply of the signature printed matter to the take-out position is insufficient. Can be prevented.

At the operation timing of sucking the suction cup, the lower side of the signature print is slightly pushed back, and air is blown from the lower side or the side of the stacked signature print, and two copies of the signature are printed. If the simultaneous removal is prevented, the accuracy of the apparatus can be improved.
