Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for contacting the pressurized gas outlet with the top surface of the printed materials when the printed materials such as newspapers are stacked on top of each other at a substantially constant pitch and sent by a carrier cord or the like. The present invention relates to a counting device for printed matter such as a newspaper, which counts the number of copies by spraying pressurized gas onto the curved upper surface formed by the bent portion of the printed material.

For example, the morning edition of printed matter such as a newspaper comes out of a rotary press with 24 pages, that is, one copy consists of 6 pages stacked on top of each other, folded in the center, and then folded again at right angles, and the evening edition is made up of 24 pages. One part of
There are relatively many 16 page pages, but 14 page, 12 page or
Sometimes it's 10 pages.

In addition, for special items such as Sunday editions, each copy is 88 yen.
Pages, 6 pages, 4 pages, and occasionally 2 pages.

Furthermore, depending on the structure of the rotary press, there are two types: a so-called folding end, in which the folded end is sent out with the bent portion facing forward, and a cutting end, in which the folded end is sent out with the bent portion facing backward.

In either case, the folded newspapers are sent out in a row, overlapping each other at a substantially constant pitch.

It is extremely difficult to accurately and quickly count the newspapers that come in this row without making a single mistake.

Previously, it was permissible to have one more copy of the standard bundles created for shipping, ie, 100 copies for a 24-page morning edition and 150 copies for a 16-page evening edition, but it was not allowed to have fewer copies.

When a newspaper company found that the total number of copies to be sent to each retailer was not a multiple of the standard number of copies, but was an odd number, they would manually count the number of copies and make the half number.

In recent years, due to the increase in power, there has been a demand for automatic counting of everything, and computers are used to store the total number of copies and command the number of copies for standard bundles and irregular bundles, making the entire line unmanned.

The present invention aims to meet this important point. There is an idea to count the number of copies by blowing pressure gas, but this method has not yet achieved a practically satisfactory effect, so further improvements have been made to fully achieve the above purpose. This is what I did to get it.

This will be explained with reference to the diagram.

In FIG. 1, 1 is a frame, 2 and 3 are pulleys around which the upper carrier cord 12 is stretched, and 5 is the axis of pulley 3. 6 and 7 are the pulleys on which the lower carrier cord 13 is stretched, 1
0 is an intermediate pulley provided on the lower inner surface of the upper carrier cord 12, and 11 indicates the axis of the pulley 10. And, as shown in Figure 3,
The stacked signature printed matter 18 is held between the upper and lower carrier cords 12 and 13 and moved in the direction of the arrow shown in FIG. carrier code 1
As shown in FIG. 4, a plurality of pulleys 2 and 13 are stretched around each pulley 2, 3, 6, and 7, respectively.

The distance between the lower surface of the pulley 3 and the intermediate pulley 10 of the upper carrier cord 12 is defined as a reference line S for its transportation.

Reference numeral 14 denotes a pressure gas outlet for counting provided between the upper carrier cords 12, 12, which is adjustably attached to the upper fixed beam 15, and the outlet 14 coincides with the reference line S. The vertical position is adjusted so that

16 is a pressure roller provided between the lower carrier cords 13, 13, and the lower fixed beam 1
Attached to 7.

The one in Figure 1 is for a folded edge, while the one in Figure 2 is for a cut edge. In the case of a cutting tip, as shown in the figure, the blower outlet 14 and the pressure roller 16 are provided at vertically opposite positions. Therefore, the reference line S in this case is a line between the upper surface of the intermediate pulley 10 and the pulley 6 of the lower carrier cord 13.

The frame 1 has screw holes for mounting the upper fixing beam 15, the lower fixing beam 17, and the fixing shaft 11 of the intermediate pulley 10, respectively, for the folding tip or cutting tip.

3 and 4 show, as an example of the printed matter 18, 24 pages of the morning edition of a newspaper, which are sent overlapping each other at a pitch of approximately 42 mm. In the figure, the air outlet 14 is fixed to a connecting plate 19, and the upper part of the air outlet 14 is connected to an air sensor 2.
0 is fitted.

Reference numeral 20' indicates a screw for fixing the air sensor 20 to the connection plate 19.

The connecting plate 19 is fixed to the L-shaped fixing piece 23 with bolts 19', and the L-shaped fixing piece 23 is attached to the base plate 2.
1, it is fixed with a bolt 23' so that it can be adjusted vertically. 22 is its adjustment screw.

The base plate 21 is attached to the upper fixed beam 15 mentioned above.
Fix it with bolt 21'.

Therefore, to adjust the level of the air outlet 14, loosen the bolt 23', turn the adjusting screw 22 to position the air outlet 14 slightly below the reference line S, and then tighten the bolt 23'. Tighten and secure.

24 is a pressure gas introduction pipe that communicates with the air sensor 20 and is connected to a pressure gas source via a pressure regulating valve (not shown).

Reference numeral 25 denotes a pressure gas outlet pipe in the air sensor 20, and its end is attached to a pressure sensor 27 attached to the upper fixed beam 15.

The pressure sensor 27 detects the curved end 18' of the printed matter 18 that is sent by rubbing the surface of the outlet 14.
The change in pressure caused by blocking the blow-off port 14 or releasing pressurized gas into the step portion 18 of the printed matter 18, which is formed by shifting and overlapping each other and having a substantially triangular cross-section, This can be conveyed.

This pressure change sensed by the pressure sensor 27 is then applied to a silicon diaphragm on the surface of which a strain gauge part is directly formed by a diffusion layer, and is detected as a voltage proportional to the minute strain that occurs on the silicon diaphragm. Above, convert it to a digital waveform and use it as a counting pulse. 27' indicates the conductor.

Reference numeral 28 is an endless belt that is stretched around a pulley 29 fixed to the shaft 5 of the pulley 3, a pulley 30 loosely fitted to the fixed shaft 11 of the intermediate pulley 10, and a tension pulley 31, as shown in FIG. , are arranged in parallel on both sides of the air outlet 14.

The tension pulley 31 is attached to the bracket 32
The bracket 32 is rotatably attached to the upper fixing beam 15 by a stepped pin 33 and a nut 33'.

A guide plate 34 is located on the back side of the endless belt 28 to align the lower surface of the endless belt 28 with the reference line S, and is also fixed to the upper fixing beam 15 with bolts 34'.

Note that this guide plate 34 can also be used as a guide roller depending on the case.

The lower surface of the guide plate 34 is coated with Teflon 3.
Apply 5.

Next, the structure of the pressure roller 16 will be explained with reference to FIGS. 5 to 7.

A roller bracket 38 is fixed to the lower fixing beam 17 with bolts 38'. Reference numeral 40 denotes a roller lever which is pivotally connected to the roller bracket 38 with a pin 39. The upper left part of the lever 40 has a bifurcated shape as shown in FIG. 6, and a center pin 41 is attached to this part.
is mounted on a shaft, and the pressure roller 16 is supported by the center pin 41. 42 is a ball bearing.

The outer peripheral portion 16' of the pressure roller 16 is formed by baking synthetic rubber having appropriate elasticity. This synthetic rubber allows the pressure roller 16 to completely close the air outlet 14 even when the thickness of one printed document is thin, such as 2 to 4 pages.
Furthermore, even when the thickness is large, the speed of movement is high, so the shock caused by the instantaneous descent at this time is alleviated.

44 is a concave groove provided in the outer peripheral portion 16',
This groove 44 prevents a counting error when one part is thin or when the signature print 18 is started to be fed.

A tension spring 49 is provided across the lower part of the roller lever 40 and the lower part of a spring adjustment lever 47 which is pivotally connected to the roller bracket 38 with a pin 46.

51 is a spring adjustment screw, 51' is its nut,
Reference numeral 50 is a square rod fixed to the roller bracket 38 and supports the head of the spring adjustment screw 51.

Links 53 and 54 are mounted on both ends of the center pin 41, respectively. and link 53,5
Between 4, 53 and 54 are stepped shafts 52 and 52, respectively.
Attach the shaft.

A pressure roller 16 is sandwiched between each stepped shaft 52,
The two first cord pressure rollers 36, 36 and the second
Cord pressure rollers 37, 37 are connected to bearings 42
It is rotatably provided through.

Therefore, when viewed in the traveling direction of the printed matter 18, a total of four first code pressure rollers 36 and second code pressure rollers 37 are provided on the right and left, front and rear sides of the pressure roller 16 with the pressure roller 16 in between.

Reference numeral 57 denotes a coil spring provided at both ends of the center pin 41, and its end sides 57', 57' engage the lower sides of the links 53, 54 so as to spring them both up.

That is, when the first cord pressure roller 36 and the second cord pressure roller 37 are pushed down from above, the coil spring 57 opens until the center pin 41 and the two stepped shafts 52 are aligned.

At this time, the abutment surface 5 of the lower end of the links 53, 54
3' and 54' collide.

When pushed down further, the center pin 41 and the first and second cord pressure contact rollers 37, 36
While maintaining a straight line with each stepped shaft 52, the roller lever 40 is pushed down while stretching the tension spring 49 using the pin 39 as a fulcrum.

Its effects will be explained.

The first bent end 18' of the printed document 18 is the first
The state before reaching the cord pressure roller 36 is the first state.
The cord pressing roller 36 and the second cord pressing roller 37 both touch the upper surface of the carrier cord 13.
It is in pressure contact with the lower surface of the endless belt 28.

The lower surface of the air outlet 14 is in pressure contact with the pressure roller 16, which is not rotating, and blows out pressurized gas into the groove 44 thereof.

At this time, the center pin 41 of the pressure roller 16
and the stepped shafts 52, 52 of the first and second cord pressure rollers 36, 37 are in a straight line.

The first bent end 18' of the printed document 18 is the first
As it approaches the cord pressure roller 36, the same roller 36 is lowered by the thickness of one part of the printed document 18, and its bent end 18' is pressed against the endless belt 28.

Since the second code pressing roller 37 is in the initial position, the pressing roller 16 is not able to handle the signature printed matter 1.
The center of each roller 16, 36, 37 does not change its position in a straight line.

When the printed document 18 is continuously fed and reaches the state shown in FIG. 5, the pressure roller 16 is pushed down at the bent end 18', and the air outlet 14 is closed at the upper surface of the bent end 18'.

When the printed document 18 is further fed, before the bent end 18' reaches the second cord pressure contact roller 37, the second bent end 1 from the head
8' reaches the first cord pressure roller 36.

At this time, the first code pressure roller 36 descends by the thickness of two copies of the signature print 18, but unless the second code pressure roller 37 descends, the pressure roller 16 will not move the signature print 18 against the outlet 14. They are in pressure contact.

When the printed document 18 is further fed and the first or second bent end 18' reaches the second code pressure roller 37, the second code pressure roller 37 begins to descend, and the pressure roller 16 also descends. , the surface pressure between the air outlet 14 and the bent upper surface 18'' of the printed document 18 disappears, and then the stepped portion 18, which has a triangular cross section, appears, so that the air flows from the blocked air outlet 14 to the stepped portion 18. Blows out pressurized gas.

and the bent end 1 of the second printed document 18
At step 8', the outlet 14 is closed again.

Counting is performed by continuously performing this state and sensing the pressure change.

It is extremely difficult to accurately count printed materials without even a single error.

For example, when counting newspapers, if the original feed or the flow is interrupted and the feed is restarted, the lower carrier cord 13 will normally be in the state shown by the chain line in FIG. Bent end 18' and bent top surface 1 of the first newspaper
8'' to the air outlet 14 completely, and the thinner the newspaper, the more
Since the carrier cord 13 is weak, it is difficult to bring the carrier cord 13 into complete contact with the air outlet 14 using only the carrier cord 13.

According to the present invention, the first and second code pressure rollers 36, 36, 37, and 37 are provided surrounding the pressure roller 16 that presses against the outlet 14 in relation to the pressure roller. , the bent upper surface 18'' of the printed document 18 is held flat under any conditions, and the same surface 18''
By always applying appropriate surface pressure between the air outlet 14 and the air outlet 14, the air outlet 14 can be completely closed off by the bent upper surface 18'' by the pressure contact of the pressure roller 16.

Therefore, even if the newspaper is a thin layer, the four circumferential surfaces around the pressure roller 16 will not have folds or uneven surfaces, and will always maintain a constant flat surface and constant surface pressure. This allows accurate counting by the step portion 18.

In addition, the second cord pressure roller 37 or the first cord pressure roller 37
By the code pressure roller 36, the printed matter 18
overcomes the resistance caused by the pressure contact between the air outlet 14 and the pressure roller 16, and smoothly prints out the printed matter 1.
8 can be fed out, this pressure contact resistance can prevent the printed signature 18 from moving in an oblique direction, or prevent the curved upper surface 18'' from curving or creating an uneven surface.
can always be brought into reliable pressure contact with the air outlet 14.
