Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an automatic folded paper opening device, and more specifically, it is useful for collating work in which a predetermined paper, such as an advertisement, is inserted into a folded paper such as a newspaper. Regarding equipment.

Previously, newspaper advertisements were collated by inserting multiple types of flyers one by one using a collating device and collating them into one set.
This was done by manually inserting each set into the newspaper.

However, this work requires a great deal of time and effort, and is a burden on the individual dealers.Therefore, there is a need to simplify this work, preferably to mechanize it.
However, in mechanizing this work, there are several problems at each stage of the work, and the newspaper separator process according to the present invention is one of them. In the mechanization of collation work, this check paper process is incorporated into the automated assembly line, so it is important that the equipment that performs this process operate quickly and at regular intervals without causing any trouble. It is essential to be able to reliably open the fed newspapers and quickly discharge the collated newspapers out of the system. Based on such theater attendance, the applicant:
Already, in Hakamabuta 187670/1970, this type of highly versatile product can be applied not only to the above-mentioned collation of newspapers and handbills, but also to collation of pamphlets, catalogs, etc. with a simple design change. We are proposing a device.

The outline thereof is shown in FIGS. 1 and 2, but for details of each part in the figures, please refer to the above cited patent application or the explanation according to the apparatus according to the embodiment of the present invention shown in FIGS. 3 and below. This previously proposed device is the basis of the present invention, and parts in the drawings that are common to the present invention are designated by the same reference numerals as those of the device according to the embodiment of the present invention shown in FIG. 3 and subsequent figures. This proposed device has V
A support 10 comprising two plates 11 and 12 positioned in a letter shape and for receiving and supporting the supplied folded paper.
and an adsorption member 25 that is attached to both the plates 11 and 12 and brings the paper and the plates 11 and 12 into close contact, and a rotatable friction ring 35 that is located between the plates 11 and 12, and one of the plates. a first barrier member 30 that opens the paper in cooperation with a friction member 18 disposed on the first paper opening member 11; and a finger 45 that runs between the opened paper after the first paper opening member 30 is operated. It is characterized in that it includes a second barrier paper member 40 and a discharge member 50 that sends out the paper from the support 10. However, in this device, the second paper separating member 40 that assists the paper separating work is based on the finger 45 that runs between the opened sheets after the operation of the first paper opening member 30. There is a problem in that the paper opening operation is not completed until the paper 45 passes between the sheets, and it takes some time to move on to the next operation. This is related to the work processing capacity of the device, and means that in order to increase the processing capacity, that is, the paper opening work speed, it is essential to increase the work speed of the second paper section 40. . However, in this device, as described above, the second paper opening member 4 is moved while the fingers 45 are in direct contact with the target paper, so increasing the passing speed of the fingers 45 is as follows: In particular, it may have a significant adverse effect on soft paper such as newspaper. The present invention has been made based on the above-mentioned viewpoints, and by making use of the advantages of the above-mentioned already proposed device and improving the second paper opening member, it is possible to solve the problem of adverse effects on the paper that is the subject of the paper. It is an object of the present invention to provide a device of this kind that can increase the work processing capacity without causing any problems. In order to achieve this, the apparatus of the present invention includes two plates positioned in a V-shape, a support for receiving and supporting the supplied folded paper, and a support attached to both of the plates, A first barrier paper that includes a suction part that brings the paper and the plate into close contact with each other, and a rotatable friction ring located between the plates, and that opens the paper in cooperation with a friction member disposed on one of the plates. a member and a half of the paper opened by the operation of the first barrier member, which is adjacent to at least the plate on which the friction member is not provided, and moves the half toward the plate; It is characterized in that it includes a two-way paper member and a discharge member that delivers the paper from the support. The present invention will be described in detail below according to preferred embodiments shown in the accompanying drawings.

FIG. 3 is a front view showing one embodiment of the present invention apparatus, which is applied to collating newspapers and handbills, and its details are omitted.

In the figure, reference numeral 10 indicates a support for receiving and supporting the supplied newspaper.
Two plates 11, 1 positioned tilted by degrees
2, and standby rollers 13 and 14 provided below both plates 11 and 12 so as to be aligned with the lower gap thereof. The roller 13 is connected to a drive source via a clutch 61a, and its operation is controlled by a switching mechanism 60a (details will be described later) that engages with the clutch 61a. The switching mechanism 60a is activated when a leaflet falls into a newspaper, which will be described later, and is configured to intermittently release the clutch 61a and immediately return to the state in which the clutch is engaged after being released.Therefore, the roller 13 is intermittently activated. 3, it rotates counterclockwise and stops after one revolution. Further, the roller 14 follows the roller 13 when it rotates. The details of the support portions of both rollers 13 and 14 are as shown in FIG. The roller 14 on the driven side is pivotally supported by a rod 15, and the rod 15 is connected to a metal fitting 17 on the main body side via a spring 16. Therefore, the distance between the rollers 13 and 14 can be freely adjusted depending on the object passing between them. Further, a roller 51 is located below both rollers 13 and 14.
, 52 is disposed, which rotates at all times to return the newspapers received from the rollers 13 and 14 to the closed state and quickly discharge them out of the system. On the other hand, a friction member 18 is fixed to the upper end of the plate 11.
Its mounting location and manner will become clear from FIGS. 3 and 9. The details of the friction member 18 are as shown in FIG.
This includes a mounting plate 19 that is directly fixed to the plate 11, four rods 20 that are slidably inserted into holes drilled in the plate 19, and a spring 21 that winds each rod 20.
A movable plate 22 fixed to the end of the rod 20 and a movable plate 22
and a friction element 23 fixed on top. Therefore, the friction member 18 can freely change the distance between the mounting plate 19 and the movable plate 22 by the pressing force acting on the movable plate 22, that is, the friction element 23. The suction member 25 is located on the side of both plates 11 and 12, and is connected to a large number of holes 24 (see FIG. 9) drilled in both plates 11 and 12 and the fan 2 installed after this.

The paper opening member 30 includes a friction ring 35 and a rod 34 projecting between the plates 11 and 12.
is connected and fixed to the end of the

The rod 34 has an inclination angle that is approximately equal to the angle of inclination of the plate 11 when viewed from the front side, and is substantially equal to the inclination angle of the plate 11 when viewed from the side side.
It protrudes at an inclination angle of approximately 45 degrees with respect to the longitudinal direction. Further, the rod 34 is connected to a drive source via gears 33, 32, 31 and a clutch 61b.
Its operation is controlled by a switching mechanism 60b (details will be described later) that engages with b. switching mechanism 60
The operation of mechanism 60a is substantially the same as the mechanism 60a described above, that is, the rod 34 is also driven intermittently, rotates counterclockwise in FIG. 3 together with the rubber ring 35, and stops after one rotation. . The details of the rubber ring 35 are as shown in FIG. 6, and include a friction surface 36 on the front side and a sliding surface 37 on the rear side with respect to the rotation direction of the rubber ring 35. The function of the two surfaces 36, 37 will become clear from the description of the operating mode of the device of the invention which will be given later. The second paper opening section 80 consists of an air pipe 81 disposed above the plate 11 along the longitudinal direction of the plate 11.

The details are as shown in FIGS. 7a, 7b, and 11, in which the side where the friction member 18 is attached to the plate 11, that is, the end 82 on the near side in FIG. 3 is closed. At the same time, the rear end is connected to an air supply V supply device (not shown), and air is constantly supplied in the direction of arrow B in FIG. A plurality of air ejection holes 83 are formed in the air pipe 81 so as to form an acute rearward angle with respect to the direction of the ball (the angle is 550 in FIG. 7a). As shown in FIG. 11, the ejection holes 83 are arranged at equal intervals toward the rear of the air pipe 81 and parallel to the axis. Also, this air pipe 81
is located above the plate 11 so that the position of the nozzle hole 83 when viewed from the plane side shown in FIG. Placed. Therefore, air is always ejected from the air pipe 81 in the direction indicated by arrow C in the figure, ie, diagonally downward and backward toward the plate 12. FIG. 8 is a partial cross-sectional view showing an example of the switching mechanism 60 used in the device of the present invention, and shows the aforementioned mechanisms 60a and 60b.
We can also learn from this mechanism.

In the figure, the spring clutch 61' is composed of a relatively rotatable driving part 62 and a driven part 63, which are wound around a spring 64, and the rotational force between the two is transmitted to the driving part 62.
This is achieved by tightening the spring 64 due to the rotation of the . A collar 66 having a protruding piece 67 on the outside is placed around the spring 64, and a claw 65 of the spring 64 engages with a notch in the collar 66. The clutch 61 is switched via the protrusion 67 of the collar 66. That is, when the spring 64 and the collar 66 rotate together with the constantly rotating drive part 62, the driven part 63 also rotates, and the protrusion 67 of the collar 66 is moved by an external force. When the collar 66 and the spring 64 try to stop rotating due to being locked, the driven portion 63 also stops. The locking and releasing of the protruding piece 67 is performed by turning off and energizing the solenoid 70, and this operation is transmitted to the protruding piece 67 via the lever bar 68. The lever 68 is pivotally supported to the frame by a ratchet 69, and is also pivotally supported by a shaft 74 to a piston rod 73 on the solenoid 70 side, and the rod 73 is normally moved outward together with the piston 71 by the action of a spring 72. When the solenoid 70 is energized, it is pulled toward the solenoid 701. When the above structure is applied to the mechanisms 60a and 60b described above, some changes may be necessary in detail, but there is no need to specifically mention these. The operation mode of the automatic opening device of the present invention having the above configuration will be described below.

The supplied newspaper is fed into the apparatus from the direction of arrow A in FIG. 3 in the manner shown in FIG. 9. The dropped newspaper is supported by the stationary standby rollers 13 and 14 with folded pieces P placed on the bales, and is also moved into the plate by the action of the fan 26.
11. At this point, the first newspaper section 30 starts operating by the action of the solenoid 70b, rotates the rubber ring 36, acts on the vicinity of the fold side Q of the newspaper, and turns it up. The outline is shown in FIG. 10. First, the rubber ring 35 presses the corner of the newspaper between its friction surface 36 and the friction element 23 disposed on the plate 11 at the position E in FIG. 10 (omitted). The newspaper is held between the sides, and as it rotates, the corner of the newspaper half S is moved relative to the other half R. At this time, the rubber ring 35 rotates at an inclination angle of about 45 degrees, which is equal to the protrusion angle of the rod 34, and moves the corner of the half body S.
As the rubber ring 35 rotates, the half body S is bent downward at an angle of 45 degrees. This state is shown by imaginary lines in the figure, and as the rubber lithog 35 rotates from position E to E', the half body S is displaced from position pupil F to F' and is greatly curved. As the rubber ring 36 continues to rotate further, the half body S passes over the rubber ring 35 due to the leaf spring action of its own curved part, as shown by F'' in FIG. At this point, the space between the corners of the halves R and S is opened.The rubber ring 35 has its friction surface 36 to open the space between the corners of the halves R and S.
When moving the corner of the body, there is a tendency to also move the half body R at the rear, but there is a sliding surface 3 on the rear side of the friction surface 36.
7 is provided, which presses the corner of the half body R, and also because the half body R itself is attracted to the plate 11,
The rubber ring 35 moves only the corner of the half body S. Even if the newspaper half S with its corner opened remains as it is, due to inertia and the suction force of the fan 27 installed on the plate 12, it slowly moves from position F'' to F''' as shown in FIG. .

However, in addition to this, when the air constantly ejected from the air pipe 81 of the second paper opening member 80, that is, forced air, acts on the half body S, the half body S is immediately pressed against the plate 12, and the air pipe 81 of the second paper opening member 80 acts on the half body S. It is adsorbed. In this case, if forced air is constantly being blown to the entire half body S, the initial checkerboard operation by the first checkerboard member 30 will be adversely affected, which may cause malfunctions. Therefore, in this embodiment, the air jet hole 83 is provided so as to be biased toward the rear of the pipe 81 as described above, and the air jet hole 83 is provided so as to be biased towards the rear of the pipe 81.
By oriented diagonally downward and backward toward 2, the sheet opening operation of the first opening member 30 is prevented from being adversely affected. However, various changes can be made to the configuration of the second barrier paper section 80, and the point is that the second open-weave member 80 is at least a paper half S on the side separated by the first barrier paper member 30. It is essential to use forced ventilation. As mentioned above, when the newspaper is completely opened, a predetermined leaflet is folded in, and after this folding is completed, the standby roller 13 is moved to the solenoid 7.
Rotation is started by the action of 0a.

As mentioned earlier, the roller 13 stops after making one rotation, but the collated newspapers that are sent out from between the loafs 13 and 14 due to this rotation are transferred to the rollers that are constantly rotating below the roller 13. It is delivered and held between 51 and 52 and quickly discharged from the system in a closed state. After this ejection, a new newspaper is subsequently fed into the support 10 of the device and collated with leaflets again in the manner described above. The present invention has been described above in detail by taking as an example the device of the present invention that is applied to collating newspapers and handbills, but the device of the present invention is highly versatile and can be used for all types of work with simple design changes. As mentioned above, it can be applied. According to the apparatus of the present invention as described above, the following effects can be obtained. First, there are two different ways to operate the seki paper: one that uses a friction ring to wind up the paper;
Since this is simultaneously performed by completely separating the opened paper by blowing forced air into the half of the rolled paper, the separator work can be carried out reliably and quickly. However, unlike the previously proposed device mentioned above, the second barrier paper member of the device of the present invention is not a hard material that is brought into direct contact with the target paper, so it can be used without adversely affecting the paper. It becomes possible to increase the paper opening operation speed, and as a result, it is possible to increase the throughput of a collating device into which the device is installed. Furthermore, since the structure of the second sheet opening member itself is much simpler than that of previously proposed devices, desirable results can be achieved in terms of product costs and problems such as occurrence of failures. As described above, according to the automatic folded paper opening device of the present invention, the advantages of the previously proposed device can be utilized as they are, and the work can be processed without adversely affecting the paper that is the target object. It is possible to improve one's abilities and achieve one's individual goals.
