Description

[Detailed description of the invention] This invention relates to a paper branching and conveying device such as a collating machine, and in particular, it simplifies the structure of introducing paper into a shelf, discharging a group of papers from the shelf, and passing paper over the shelf. The present invention relates to a paper branching and conveying device such as a collating machine that reliably performs paper branching and conveying.

When aligning and collating the pages of copy paper, etc., install multiple paper receiving shelves (bins) in the machine, either fixedly or movably, depending on the number of copies required, and paper with the same content is placed in each shelf. They are being introduced in stages. Further, the group of sheets with aligned pages is ejected by a separate ejecting device or the like.

Therefore, each device for introducing the paper into the shelf and discharging the paper group from the shelf is required, resulting in a complicated device configuration and an obstacle to making the device more compact.

On the other hand, as a paper storage and conveyance device,
A sorter was proposed in Japanese Patent No. 33533, in which a conventional sorter in which a plurality of tray plates made of rigid material are fixed radially to a rotary body is loaded with paper by a paper discharge device having a fixed gate. A device for sequentially dropping and storing objects is described as a conventional example. However, since this device ejects the paper using natural falling, the device becomes larger in the vertical direction, and it is difficult to eject the paper to the desired position, especially to the side or upward. The disadvantage was that the paper ejection device was limited. Since this device uses natural falling, paper often remains in the sorter if the tray plate and paper do not slip well when ejecting after page alignment etc. There was a drawback that this occurred and resulted in missing pages.

In addition, a collating machine system was proposed in Japanese Patent Application Laid-open No. 52-86817, in which sheets stored in a shelf are rotated by a spider-shaped device having a plurality of friction wheels around it. A sheet ejecting mechanism is disclosed that pulls the sheet backward each time. However, this mechanism simply takes out the sheet using a friction ring, and it is impossible to set different take-out positions, so it lacks versatility. Therefore, it has been impossible to set the sheet ejection position in an extra space within the apparatus in order to make the apparatus more compact.

Furthermore, a copying device was proposed in Japanese Patent Application Laid-open No. 53-138743, in which gates are provided at the front and rear of the conveyor roll to stop the sheet at a predetermined position, ensure that the sheet is introduced into the conveyor roll, and then discharge it in a fixed direction. A mechanism for doing so is disclosed. However, this mechanism is a mechanism in which the sheet is introduced into the transport roll through an alignment gate that swings to function as a stopper for stopping the sheet at a predetermined position and a gate, and other than that it also functions as a stopper. Since it plays the role of a guide, it is difficult to set the sheet introduction direction and sheet ejection direction separately, and it has the same drawbacks as the sheet take-out mechanism proposed in the collation machine system described above.

This invention was devised to solve the above-mentioned inconvenience, and its gist is that the entire cylinder has a cylindrical shape, and a large number of paper receiving shelves are arranged on the circumferential surface of the cylinder at regular intervals in the axial direction, and are inclined to the circumferential surface. A binding device is made up of a bind drum provided, an introduction device placed near the bind drum to introduce a group of sheets into the bind drum, and a binding device placed above the introduction device to bind the group of aligned sheets discharged from the bind drum. In a paper branching conveyance device such as a collating machine that forms a combiner and branches and conveys sheets from an introduction device to a binding drum and a group of sheets from the bind drum to a binding device, it is arranged in front of the paper feed of the introduction device and driven to rotate. a conveyance roll; a conveyance pressure roll rotating in opposing contact with the conveyance roll; an introduction gate disposed between the opposed contact portions of these rolls and the introduction device; and an introduction gate for the opposed contact portion. a shelf gate disposed on the opposite side of the gate and having a tip thereof located within the paper receiving shelf;
It consists of a presser gate disposed opposite the shelf gate, and a solenoid connected via a swing arm to each swing shaft mounted on the shaft so that each of these gates can swing freely. The conveyance pressure roll is constructed by mounting the pressure roll shaft on which the roll is rotatably supported so that it can move in the direction toward and away from the conveyance roll and elastically press the pressure roll in the direction of the conveyance roll. It is pressed against the
The shelf gate is formed by appropriately arranging a plurality of gate plates perpendicular to the pressure roll, and the shelf board of the paper receiving shelf has a structure in which the tip of the shelf gate is located within the paper receiving shelf. In order not to interfere with the rotation of the bottle drum, a notch is formed through which the tip of the shelf gate passes, and the introduction gate is formed by bending the end of the flat bottle drum side at an acute angle to the opposite side of the introduction device in cross-section. When located on one side, the paper is sent from the introduction device to the binding drum, and when it is located on the other side, the movement of paper from the introduction device is blocked and the paper group from the binding drum is guided so that it can be sent to the binding device. When a group of sheets is introduced into each paper receiving shelf from the introduction device, the solenoid rotates the transport roll in the forward direction, and rotates the bin drum in the forward direction to each paper receiving shelf through the introduction gate, shelf gate, and presser gate. In order to introduce the paper groups sequentially from the paper receiving shelves to the binding device, each paper receiving shelf sequentially moves toward the apex of the circumferential surface by reverse rotation of the bin drum. The sheets of paper that are gradually rising in the direction of rotation of the circumferential surface of the paper are scooped up at the tip of the shelf gate and guided to the opposing contact area between the conveyance roll and the conveyance pressure roll, and the sheets of paper are bound by reverse rotation of the conveyance roll. In order to carry out branched conveyance to the apparatus, and furthermore, to directly discharge unneeded paper when it is conveyed, the swinging and holding of each of the gates is controlled, and the drive of the bin drum and the drive of the conveyance roll are the same. This is due to the fact that it was formed to be carried out in the drive system.

A pivot plate 1 having a gate plate 11 whose end on the side of the bin drum 44 is bent at an acute angle on the opposite side of the introduction device 55 and a swing shaft 12 for pivotally attaching the gate plate 11 to the side plate 5.
It consists of 3. A swing arm 14 is fixed to the end of the swing shaft 12, and a plunger 15A of a solenoid 15 is connected to the other end of the swing arm 14. A tension coil spring 16 is disposed at the other end of the swing arm 14 on the side opposite to where the solenoid 15 is arranged, and a tension coil spring 16 is provided to keep the swing arm 14 swinging at all times. When the plate 11 is located, the paper is transferred from the introduction device 55 (described later) to the bin drum 4.
4, and when the gate plate 11 is located on the other side, it is formed to swing so as to block the paper from the introduction device 44 and guide the paper group from the bin drum 44 to be sent to the binding device 49.

is fixed to the shaft end of the swing shaft 31, and a swing means similar to the introduction gate 10, that is, a swing arm 33, a solenoid 34 having a plunger 34A at the tip of the swing arm 33, and a solenoid 34. It consists of a tension coil spring 35 disposed at the tip of the swing arm 33 on the opposite side.

The paper branching and conveying device configured in this way has shelf 4.
It is used by placing it above the opening of No.3. FIG. 3 shows a collating machine 40 using the paper branching and conveying device according to this invention, which has a cylindrical shape as a whole and has a large number of paper receiving shelves 43 arranged at regular intervals in the circumferential direction on its circumferential surface. A plurality of bin drums 4 are formed at an angle with respect to the
4 is mounted on a machine frame 45, and an introduction device 55 for introducing a group of sheets into the bin drum 44 is disposed near the bin drum 44. Above the introduction device 55,
It is provided as a paper branching and conveying device for a collating machine 40 which is formed by disposing a binding device 49 for binding a group of sheets with aligned pages discharged from a bin drum 44.

The tip of the shelf gate 20 is connected to the bin drum 4.
Therefore, when the bin drum 44 is rotated, the shelf board 46 portion where the shelf gate 20 is located has a shelf along the circumferential direction of the bin drum 44. A long notch 47 is formed through which the tip of the gate 20 passes, so that rotation of the bin drum 44 is not hindered.

Normally, each gate 10, 20, 30 is held in a swinging position as shown by the dotted line in FIG. That is, the introduction gate 10 is held at a swinging position that guides the paper from the paper introduction device of the collating machine 40 to the opposing contact portion between the conveyance roll 1 and the conveyance pressure roll 3, and the shelf gate 20 and the presser gate 30 are It is held in a swinging position to introduce paper into the paper.

If paper of a different size than the paper to be introduced into the shelf 43 is conveyed, or if copy paper with the same content has already been introduced into each shelf 43, a control mechanism (not shown) will move the paper to the shelf. The solenoids 24 and 34 of the gate 20 and the presser gate 30 are energized to swing the shelf gate 20 and the presser gate 30 upward, respectively, so that the paper is branched and conveyed in the direction of the paper discharge roll 48.

In addition, when discharging a group of sheets with aligned pages in the shelf 43, the solenoids 34 and 15 of the presser gate 30 and the introduction gate 10 are energized, and the presser gate 30
is swung upward, and the introduction gate 10 is swung downward. Thereafter, the bin drum 44 is rotated reversely by the opening length of the shelf 43, that is, rotated clockwise in FIG. 3. The transport roll 1 and the bin drum 44 are each connected to a drive system including the same drive motor 41, and are configured so that when the bin drum 44 rotates in reverse, the transport roll 1 also rotates in the reverse direction. Therefore, each shelf 43 sequentially moves toward the apex of the circumferential surface by the reverse rotation of the bin drum 44, and thereby, the sheet group rising in the rotation direction of the bin drum 44 is scooped up from below by the shelf gate 20.
It is inserted into the opposing contact portion between the conveyance roll 1 and the conveyance pressure roll 3 guided upward by the shelf gate 20. Since the conveyance pressure roll 3 is mounted on a shaft via the elongated hole 6 of the side plate 5, it is separated from the conveyance roll 1 by an amount corresponding to the thickness of the paper group at the same time as the paper group is gripped, and the thickness of the paper group is Correspondingly, the sheets can be held and conveyed by two groups of rolls 1 and 3, so that the group of sheets is branched and conveyed to the binding device 49 arranged above.

At this time, the gate plate 11 of the introduction gate 10 is
By forming the end of the flat bin drum 44 in cross-sectional shape to be bent at an acute angle on the opposite side of the introduction device 55, the sheet group is conveyed from the two rolls 1 and 3 toward the binding device 49. Sometimes it can be conveyed smoothly, and if the group of paper falls for some reason, the bent part acts as a claw to prevent the group of paper from falling, and the group of paper is transported without letting the group of paper fall any further. It is designed so as not to interfere with the

The paper group that has been branched and conveyed upward is stapled at one side edge by the stapler 50 and perforator 51 of the binding device 49, and a binding hole is punched. The paper is discharged into the paper tray 54.

In such an operation, that is, when introducing a group of sheets from the introduction device 55 to each paper receiving shelf 53, each sheet is transferred through the introduction gate 10, the shelf gate 20, and the presser gate 30 by the forward rotation of the transport roll 1. In order to sequentially introduce paper groups into the receiving shelf 43 while rotating the bin drum 44 in the forward direction, and when conveying the paper group from the paper receiving shelf 43 to the binding device 49,
The bin drum 4 is moved by each paper receiving shelf 43 that sequentially moves toward the apex of the circumferential surface by the reverse rotation of the bin drum 44.
4 is scooped up by the tip of the shelf gate 20 and guided to the opposing contact area between the conveyance roll 1 and the conveyance pressure roll 3, and the conveyance roll 1 is rotated in the opposite direction. The introduction gate 10 and the shelf gate 2 are operated so that the group of sheets is branched and conveyed to the binding device 49, and furthermore, when unneeded sheets are conveyed, they are directly ejected.
0. The presser gate 30 is controlled by the solenoids 15, 24, and 34 to swing and hold at positions suitable for the respective operations described above.

This device is constructed as described above, and includes a bin drum 44 which has a cylindrical shape as a whole and has a large number of paper receiving shelves 43 provided at regular intervals in the axial direction on the circumferential surface thereof, and a bin drum 44 which is inclined to the circumferential surface. An introduction device 55 is arranged nearby and introduces a group of sheets into the bin drum 44.
and a binding device 49 which is disposed above the introduction device 55 and binds the group of sheets with aligned pages discharged from the bin drum 44, forming a collating machine 40. In addition, in a paper branching and conveying device such as a collating machine that separates and conveys groups of sheets from a bin drum 44 to a binding device 49, an introduction device 55 has a conveyance roll 1 disposed in front of the paper feed and driven to rotate, and a conveyance roll 1 that faces and contacts this conveyance roll 1. A conveying pressure roll 3 that rotates is provided, and an opposing contact portion of these rolls 1 and 3 and an introduction device 55
Since the collating machine 40 has the introduction gate 10 disposed between the collating machine 40 and the
Inside, the copy paper etc. sent from the introducing device 55 can be reliably guided to the opposing contact portions of the rolls 1 and 3.

Then, the introduction gate 1 is connected to the opposing contact portion.
Since it has a shelf gate 20 disposed on the opposite side of the shelf gate 0 and a presser gate 30 disposed in a position opposite to this shelf gate 20, the discharge position of the paper group discharged by each roll 1, 3 is fixed. can be easily set up.

Further, the conveying pressure roll 3 is capable of moving a pressure roll shaft 4 on which the roll 3 is rotatably supported in a direction toward and away from the conveying roll 1, and elastically presses the pressure roll shaft 4 in the direction of the conveying roll 1. Since it is in pressure contact with the transport roll 1 by being mounted on an axis, it is possible to transport only a single sheet of paper or a group of stacked sheets without applying excessive force to each roll 1, 3. Become. That is, since the conveyance pressure roll 3 escapes outward in the elongated hole 6 by an amount corresponding to the thickness of the sheet group, a large load is not applied to each roll 1, 3 and each shaft 2, 4.

By positioning the tip of the shelf gate 20 within the paper receiving shelf 43, it is possible to press down the paper group that has already been introduced into the shelf 43 from above, thereby reliably forming a space for introducing the next paper into the shelf 43. Therefore, the pages of the paper can be aligned accurately.

Furthermore, the introduction gate 10 is formed so that the end on the side of the flat bottle drum 44 in the cross-sectional shape is bent at an acute angle on the opposite side of the introduction device 55.
When conveying a group of sheets from the two rolls 1 and 3 to the direction of the binding device 49, it can be conveyed smoothly, and if the group of sheets falls for some reason, the bent part will be caught by the claw that prevents it from falling. It is designed to fulfill its role and prevent the paper group from falling any further, thereby preventing any hindrance to the conveyance of the paper group.

Moreover, the shelf gate 20 includes a plurality of gate plates 21.
are appropriately arranged and formed so as to be perpendicular to the pressure roll 1, and on the shelf board 46 of the paper receiving shelf 43,
In order to prevent the rotation of the bin drum 44 from being hindered even if the tip of the shelf gate 20 is located in the paper receiving shelf 46, a notch 47 is formed through which the tip of the shelf gate 20 passes.
4 and 34, when introducing a group of sheets from the introducing device 55 to each sheet receiving shelf 43, the transport roll 1 is rotated in the forward direction, and the paper group is transferred to each sheet receiving shelf 46 via the introducing gate 10, shelf gate 20, and presser gate 30. In order to sequentially introduce the paper groups while rotating the bin drum 44 in the forward direction, and when transporting the paper groups from the paper receiving shelf 46 to the binding device 49, the bin drum 44 is rotated in the reverse direction to sequentially introduce the paper groups in the direction of the apex of the circumferential surface. The sheets of paper that are being raised in the direction of rotation of the circumferential surface of the bin drum 44 by each of the moving paper receiving shelves 46 are scooped up by the tip of the shelf gate 20, and the conveyance roll 1 and the conveyance pressure roll 3 come into opposing contact with each other. The respective gates 10 and 2 are used to guide the group of sheets to the binding device 49 by reverse rotation of the transport roll 1, and to directly discharge unneeded sheets when they are transported.
0 and 30, each gate 10, 20, and 30 is connected to the solenoid 1.
5, 24, and 34, it is possible to hold the group of sheets so as to reliably feed them toward the position to be transported,
The swinging of each gate 10, 20, 30 can be performed quickly with a simple structure. Also, shelf gate 20
By swinging between the presser gate 30 and the presser gate 30, unnecessary sheets can be discharged outside the machine frame 45 without being introduced into the shelf 43. Therefore, by connecting the collating machines 40 and the like using this branching conveyance device in series, it is possible to use a plurality of bin drums 44 and to collate a large number of copies or to align the pages.

Furthermore, since it is used in combination with the bin drum 44, it becomes extremely easy to eject a group of sheets. That is, in the past, it was necessary to eject a group of sheets by using, for example, a sheet group pushing means, but according to this invention, by reversing the bin drum 44, the shelf gate 2
Since the group of sheets can be scooped up and sent to the opposing contact portions of the rolls 1 and 3 by the zero, the group of sheets can be discharged very easily, and the structure can be simplified.

Then, the drive of the bin drum 44 and the conveyance roll 1 are performed.
Since the drive of the bin drum 44 and the transport roll 1 are configured to be driven by the same drive system, the forward and reverse rotations of the bin drum 44 and the transport roll 1 can be switched at the same time. Therefore, when conveying a group of sheets to the binding device 49, conveyance errors such as directly ejecting the sheets to the outside of the machine frame 45 or conveying them back to the introduction device 55 do not occur at all.

On the other hand, the notch 47 provided in the shelf board 46 prevents the rotation of the bottle drum 44 from being hindered even if the tip of the shelf gate 20 is present in the shelf 43; Since the tip of the shelf gate 20 is completely positioned on the shelf 43, scooping of the shelf gate 20 when conveying a group of sheets to the binding device 49 by rotating the paper in the reverse direction can be carried out reliably.

As explained above, according to this invention, there is no need to provide a separate introducing device and ejecting device for a collating machine, page aligning machine, etc., and the device can be made compact, and the structure is simple. In addition, it can be easily controlled to ensure reliable operation, and has various effects that are extremely useful in practice, such as being able to minimize troubles such as breakdowns and paper jams.
