Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combination device having both functions of collation and paper folding in a bookbinding process.

Traditionally, in the bookbinding process, if the paper is of a certain size and does not need to be folded, it is only necessary to collate it using a collating machine.
If the size of the paper is not constant and even large ones get warm, two steps are required: fold the paper by folding it 9 times, and then collate it by hand or using a collating machine, and this rounding process There are 6 to 9 cases where this is unnecessary and the number of man-hours increases accordingly.

The present invention has one objective: to provide a paper collating device with a paper folding function so that collation and paper folding can be performed at the same time; This is a complete product designed to eliminate the drawbacks of the conventional technology.

The present invention will be explained below with reference to an embodiment shown in the drawings.

The combined folding and paper folding device of the present invention includes a plurality of paper stacking tables 2 housed in a housing 1, a pickup 4 provided corresponding to each stacking table 2, and a paper stacking table 2 that is arranged in a stacked position. It is composed of a group of transport conveyors, a positioning table 10, a paper folding mechanism 15, and a stacker.

Inside the housing 1, there are paper loading tables 2 arranged in multiple stages at predetermined intervals.
are distributed and stored, and the utensils 3 are stacked on the loading table 2. The same number of pickups 4 and paper feed rollers 5 as the number of paper loading tables 2 are provided in the vicinity of the weaving opening of each paper beak loading table 2. The pickup 4 then reciprocates in an arc between the paper loading table 2 and the paper feed roller 5 at all stages at the same time, and takes out the papers 3 one by one.

Each conveyor n constituting the conveyance means consists of a vertical conveyor 7 and a horizontal 1-y4m conveyor 8.9, and the i# type conveyor T is located on the take-out D side of the paper feed roller 5. It is designed to be driven by a drive mechanism (not shown).

Immediately below the vertical traveling conveyor 7, nine horizontal #il transport conveyors 8 corresponding to the vertical traveling conveyor 1 are connected to a support mechanism (not shown) (thus arranged in parallel, t7'?@1
At the upper part of the conveyor 8, adjacent to the vertical double conveyor 7 and at the rear, a second @week conveyor 9 is arranged in a row IIK by a support mechanism (not shown). Said 1st @2@
All of the conveyors are driven by an @@ mechanism (not shown).

There is a positioning table IO behind the #1 transport conveyor 8, which is on the same plane as the first transport conveyor 8 and inclined with respect to the traveling direction of the paper 3 so as to have an appropriate angle α in the transport direction. A horizontal first transport conveyor 11 and a third transport conveyor 11 are provided with a plurality of suitable holes 13 facing each other.
A ball receiving plate 14 that rotatably holds a ball 13a such as a ball 13a.
Nine guides are provided on the ball receiving plate 14 so as to convey the paper while aligning one side edge of the paper sandwiched between the eighth feeding conveyor 11 and the balls 13 & of the ball receiving plate 14. 2.

And the first @ transport conveyor 8 and the 1s2 transport conveyor 9
The third conveyor 11 rotates at the same speed as the paper feed roller 5 and the vertical conveyor 1, while the third conveyor 11 is rotated at the 111th! It is designed to rotate at a faster speed than the feed conveyor 8 and the like.

Behind the positioning table 10, there is a folding mechanism section 15, which includes upper and lower conveyor rollers 16, 17, a folding buckle 18 with an inner SK stopper 18a, and a conveyor roller 1.
9.20, and eggplant 21, and paper ejection upper and lower a-ra 22.2
3, each of which is driven by a drive mechanism (not shown).

This paper folding mechanism section 1 is located behind the paper folding mechanism section 15.
There is a stacker that is ejected from 5 and stacks mourning papers.
It consists of a rotating part and a fixed part.

A pedestal is fixed to the center of the base plate of the fixed part P, and 44 has several IJ upright members 26) with a σ-ra 26C at the top.

Said group! A rotary table 241L is mounted on the upper part of the rotary table 241L, and a round shaft lower than the lower surface of the central part thereof is bored in the pedestal 26a and supported in a round hole, so that it can rotate around the pedestal 26a. It has become. The member 26b is in constant contact with the periphery of the back surface of the rotary table 24L. , to stabilize the rotary table 24&, and when the table 24a rotates, the a-ra 26c provided at the top is in contact with the lower surface of the table 24m while rotating. It's so hot.

A plurality of abutting pins U are provided on the upper surface of the rotary table 24a to stop the conveyed sheets and align the vertical and horizontal surfaces.

! The rotary table 24 & mentioned above can be rotated 90 degrees from ON/0FFK of the illustrated cam switch, and this cam switch allows the pickup 4 to
A cam (not shown) rotates once every time the paper feed q and the roller 5 reciprocate.

Then, the stacker rotates every time one set is discharged onto the rotary table 241, and when 51 sets of K are discharged, #i! The i-cam switch is great. M and rotated 90 degrees, changing the orientation of each set of 9911 so that they are separated and stacked.

Next, the production of the above-mentioned example will be explained.

When a drive switch (not shown) is turned on, the nine sheets 3 stacked on each stacking table 2 are carried one by one by the pickup 4 to the sheet feeder a-25, so the sheets are sent to the sheet feed roller 5. 6 is in contact with the vertical winding conveyor 7,
It is sent along this and sent to the first transport conveyor 8 installed laterally in the lower part.

Here, when the vertical spacing of each loading platform 2 is ■, and the length of the paper of the maximum specification size is L, in the case of paper of the maximum specification size,
When one sheet is sent simultaneously from the upper and lower stages of each loading platform 20, the lower stage is sent to the transport compare 8 faster than the upper stage.
Therefore, the front of the upper paper is the rear of the lower paper!
! −L=Lfe will be sent overlappingly.

Since the second conveyor 9 is provided oppositely above the first W1 conveyor 8, the 111th conveyor 8
The interval of 1 klJ between the surface of each bell of the second transport conveyor 9 is slightly thicker than the maximum specification for two sheets of paper (for example, 0.5-
Since the second @ feed conveyor 9 rotates at the same circumferential speed as the paper feed roller 5, the vertical fJ1WIi feed conveyor γ, and the 141st feed conveyor 8, the paper 6 has two overlapping sheets. Even if there is a problem, it will be transported without any hindrance.

The paper sheet 6 passing through the first-'42 transport conveyor 8.9 is sent to the positioning table IO.

3112nd conveyor 11rL said first conveyor 1
The traveling direction of the paper 3 (
On the other hand, since the paper is slanted, it eliminates overlapping sheets of paper at the same time as horizontal alignment, and the first and second transport conveyors 8.9 also transport the paper faster, so fitJuk's paper relationship Only a strange 1Δt can be thrown out.

t'fi-1 3rd!11 On top of the conveyor 11, a ball 13a made of resin or the like is inserted into the steel plate and a round ball receiving plate 14 is inserted.
is provided, so the paper 6 is transferred to the third conveyor 11.
It is held between the balls 13a of the ball receiving plate 14 and conveyed along the left side along the guide t2.

The paper 6 then reaches upper and lower transport loaves 16 and 17 forming part of the paper folding mechanism 15, and is then fed into the folding buckle 18 located at the rear. When the leading edge of the paper 6 reaches the flange 181LKfi in the folding buckle 18, the paper 6 is bent in the middle in the longitudinal direction because it is fed further back by the older brother who cannot advance it any further.

Therefore, this time, the nine bent points become the leading ends and are completely folded by a set of conveying rollers 17 located below the folding buckle I8, and four folds which are further held and conveyed.

Then, move the conveyance rollers 19 and 20.2m further downward by 4+l, and stack the stacker 2 with the upper and lower paper discharge rollers 22 and 4.
4. The sheets are ejected one by one onto the top.

The paper is discharged onto the stacker 24 and placed on the rotary table 2.
The vertical and horizontal surfaces are fixed in front by nine abutments 25 provided on the paper sheet 4a, and each time one set of paper is discharged, the paper is rotated 90f, folded, and the nine sheets are collated and stacked alternately in a good condition.

Although we will explain the case where a folding buckle is used in the paper folding mechanism section of the illustrated embodiment, it goes without saying that the same effect can be obtained by using a knife folding mechanism, and the invention is limited to this folding buckle. It's not a thing.

As explained above, in the present invention, the first folding and the paper folding 9 are performed in the same process, which reduces shrinkage and man-hours in the process, and eliminates waste as in the conventional method. It is effective.
