Abstract

PURPOSE:To relieve sheets from shocks and prevent wrinkles from being generated in the sheet, by a method wherein the sheets are preliminarily accelerated by a pusher which precedes a pusher pin for pushing out the sheets placed on a mount table, in a sheet accelerator for a gathering machine which is a preparatory machine in bookbinding. CONSTITUTION:In the gathering machine, before the pusher pin 31 acts on the sheets 23 dropped on the mount table 61, the sheets 23 are accelerated by the pusher 66 which is moved forwards at a speed lower than the velocity of the sheets 23. Then, the pusher pin 31 gradually catches up with the sheets 23 being moved forwards, the sheets 23 are transferred from the pusher 66 to the pusher pin 31 and are moved forwards by the pin 31. Accordingly, the sheets 23 are pushed out from the table 61 onto a conveying table 28 while preventing any shock from being applied to the sheets 23 and preventing warp or wrinkle from being generated in the sheets 23.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a collating machine which is a preparation machine for bookbinding.
Paper fog acceleration f11 that accelerates the paper to near the conveyance speed in advance
The collating machine, which is a preparation machine for bookbinding, is related to K.
The IN is constructed as follows by Jubeiji. That is, this type of collating machine is equipped with a plurality of paper stacking boxes arranged along a paper conveyance path), and a paper feed cylinder is provided below each pothole.

The paper sheets stacked in the box are sucked up by the suction mouth and turned over, and the paper sheets stacked in the box are held in the claws of the rotating paper feed cylinder and attached to the m-side KII of the cylinder. The paper sheets are released from the claws on a platform provided for each paper feed cylinder and fall onto the platform. A conveyor chain that runs along the conveyor belt that extends over the entire length of the machine is installed below the platform. The paper slips are pushed out onto the conveyor table by the butsushapin, and by repeating this process for each loading table, the paper slips placed on the conveyor table are pushed by the butsushapin and placed on the carpet table. Transported with care.

However, in such conventional collation II, the good paper falls onto the loading table and remains stationary for a moment, whereas the butsushabin runs at a considerably O speed, so one paper 1iiiFi It is rapidly accelerated from zero to butsushabin's rectangular speed acupuncture. This impact can cause paper sheets to warp and wrinkle, or to be ejected in a distorted state against the main Fi conveyance table, causing work problems. The next step is to limit and improve work efficiency.

Therefore, in order to eliminate this drawback,
2, a proposal was made to show the grammatical value in Figure Il1. To explain this based on the same figure, below several III boxes 10 arranged in parallel from the front side of the figure toward the back side of the paper at the upper end of the machine base, a paper feed cylinder shaft 2 is mounted along the entire length of the machine base. A plurality of paper feed cylinders 3 are mounted on a rack and are pivoted in correspondence with each box 1Vζ. In addition, a good guide shaft 4 is supported over the entire length of the machine on the paper feed cylinder 20 bale side.
A candlestick tube 5 is slidably fitted therein, and a plurality of blocks 6 pivotally attached to the tube 5 correspond to the paper feed cylinder 3, and the paper spine shown in the figure A platform 8 whose II is closed by a wall 7 and whose front side is open is supported by each block 6 via a support shaft 9. Nine, the bottom of the platform 8 -1yc is
The transport platform 10 extends over the entire length of the machine with support 514.
Below that, there is stretched a conveyor chain 12 that runs from the back side of the diagram to the hand and the back of the picture. With this configuration, the amount of cargo loaded in box 1 is
The paper 111113 that has been removed is caught by the paper feed cylinder sO claw which rotates in the direction shown by arrow A in the figure, and is ejected onto the holder 6. The ejected paper I[13 is pushed out onto the conveyance table 10 by the moving shovel bin 11, and then is subsequently pushed by the pusher pin 11 and conveyed on the conveyance table 10. A device for moving the &socket 8 back and forth is provided in this 41-piece V. That is, an outer ring 1b is rotatably fitted into an inner ring 14 fixed to one end of the paper feed shaft 2 so as to be aligned therewith, and one end of a connecting rod 16 is screwed into the outer ring 15. has been done. On the other hand, a YTM receiver 17KFi is provided at the rear end of the 4m stand frame, and a rotating body 18 is rotatably supported, and this rotating body 18 also has a lever (not shown) extending toward the front in the figure. The other end of the connection-rad lli is connected to the tip of the connection-rad lli via a ball joint. Also,
The free end of the lever 18, which extends from the rotating body 18 parallel to the connecting rod 11, is connected to the tube 5 by a tension clot 20 with a ball l1s-vs at the III end.

In this way, when the paper feed cylinder shaft 2 rotates, the outer ring 1s rotates eccentrically, and the connecting rod 16 reciprocates in the left and right direction in the figure, so that the lever (not shown) tube through the body, lever 19 as well as tension clot 20! 1 reciprocates on the guide shaft 4, so that
The supported platform 8 reciprocates toward the paper sheet IsO@feeding material. The movement in one of these reciprocating movements is
By synchronizing it with the 0-travel and making it crawl, the paper 1i13Krj on the platform 8, before the paper 11 comes in contact with it, moves in the same direction at a speed slightly slower than its traveling speed. Since this motion is imparted, the following problems mentioned above are resolved.

However, in the conventional OiIm configured as described above, when the paper sheet 11 is attached to the sheet 1t13ecffl and the loading table 8 is moved back, the paper sheet 13 is still placed on top of the pile. D. Placement table 8 is paper It
31 Since it tries to pull back in the opposite direction, the loading table S and paper sheet 1
3 will rub against each other, causing damage to the paper surface. In addition, the reciprocating part I is not made up of the platform 8, the support shaft 9 that supports it, the block 6, and the pipe 5, which are heavy as a whole, so the operating load is large and the durability is poor. , even if we tried to increase the speed by installing an accelerator,
The drawback was that it was difficult to achieve large speed increases due to the high load.

The present invention is a companion to the above-mentioned points, and includes a stacking table fixed to the machine frame side, and a paper mt extrusion pusher bin on the loading table.
Paper II is supported by a guide S that can be raised and lowered and is to be conveyed by a push shovel by providing a push shovel that moves back and forth at a slow and moderate speed in advance of the push shovel! By applying acceleration to the paper in advance, the lightweight wII4 is used to extrude paper sheets without damaging the paper surface. By making it possible to prevent the occurrence of wrinkles and unauthorized discharge, it is possible to improve quality and increase operating speed by reducing the operating load by 0%. By engaging with the recess provided in the mounting plate, the accelerating movement of the paper sheet due to the pusher can be accelerated.
The purpose of the present invention is to provide a Jin accelerator for a machine that achieves the above objectives.

By loosening the nut 6T and rotating the support bin, the height of the filter 6s is adjusted by displacing the outer peripheral surface due to the centripetal action. 1. The distance from the top surface of the top surface is adjusted.

The operation of the collating machine constructed as described above will be explained. First, the first stage box 22 is loaded with, for example, four-folded sheets of paper [13] having pages 21 to 8, and the second stage box 22 is loaded with paper [13], which has been folded into four and has pages 21 to 8. ! 13t of paper sheets are stacked according to the ordering II order, such as loading 1m of paper for pages 't11 from KFi page 9 to page 16.
- Prepare. Then, when the prime mover is started, the paper feed cylinder shaft 2
4 and the driving shaft 40 make a complete turn, and the conveyor chain 28 runs. When the rIA motor 40 rotates, the claw 26 of the paper feed cylinder 25 is sucked into the suction port 2T, grips the edge of the paper 123 at the bottom of the multiplication table, and pulls it out. 61, it is released from the claw 2 and falls onto the platform 61.

On the other hand, the flange 4T integrated with the driving shaft rotates 40,000 times.
The signal is then transmitted to the bevel gear 42 via the pin 46, lever 44, and cam follower 45, and further transmitted to the driven shaft 4 via the bevel gear 43 that meshes with the bevel gear 42. and,
The rotation of the driven shaft 410 is transmitted to the holder 50 from the flange 49 which is integral with the driven shaft, and the rotation of the holder 5 is caused by the rotation of the shaft 410. 11 by screw shaft i4 and crank I3
1KK is exchanged, and the support pipe ss connected to the crank s3 through the plotter Ilt moves 111 times. However, the support tube 81KII is fixed, and several guide brackets @2 move back and forth, and this guide bracket 1
The guide rod @ 4 and the pusher @ 6 supported by the id roller @ 3 on the lower end of the guide rod @ 4 and the pusher @ 6, which are lowered by their own weight, also move back and forth on the lower end of the rolling roller @ st Hajime 61. . Among these pros and cons, first of all, *
In 1, since the button i@ is adjusted upside down by the rotating roller 6s, the lower II #A is moved from the top of the platform @1 by a small distance in a round shape 1. . Placement stand 61
As mentioned above, the paper 1i28-fi has fallen and is placed on top, so this paper 128 is pushed onto the SSO push plate... You can feel the acceleration from Ij1 or Zeq to Busha 6/O running speed. Butsushabin 31 from behind paper leaf 23 to Sonin
The Sunbea chain runs at 2m and 4, but Butsusha 66's l! Since the itl advance speed 1 is set to approximately V3 of the running speed of the busher 310, the busher 31 catches up with the busher 6g during its forward movement, takes over the sheet 23 from the busher 66, and moves it forward. Then, the advanced paper lI23 is pushed out from the tip of the platform 61 onto the conveyor table 21, and is subsequently conveyed by being pushed down on the conveyor table 28 by the shovel s1. t+, the busher 66 that took over the paper sheet 23 to the busher bin 31 transfers the next paper 1a.
Return to the original position and wait before 23 falls.

By repeating such an operation at each station, the paper sheets 2s are conveyed onto the conveyance table 26 while being stacked and stacked on page #. In addition, at the start of operation, by controlling Kl so that the opening/closing timing of the suction claw 26 of the suction port 2T is shifted by K for each station, the arrangement of paper sheets 23 in the first cycle can be controlled normally. , from the second cycle onwards, each station O
By switching to perform the paper feeding operation all at once, the collating operation is performed continuously thereafter.

As explained above, 1 this collation 41! In this case, it fell onto the table 61 and the paper 1123 was crushed by the scraper 31.
Before the action takes effect, its running speed is also accelerated by the button moving forward at a crawling speed! 4 is applied, and the paper sheet 31 moves forward, gradually catching up with the sheet 23, so that the impact 't-4 does not occur against the paper 1123, and the paper ml! 1 will not warp and wrinkle XK. 9. Since the bushing 66 only touches the rear end of the paper 123 and does not touch the printing surface as in the conventional case, it can damage the paper surface not only when advancing, but also when reversing. In addition, since the reciprocating members are only the lightweight bushing 68 and its attached parts, rather than the platform 61 as in the conventional case, the operating load is extremely small. Further, a protrusion 113@@e is provided at the lower end of the bushing 66 to engage with the cut groove 61.,@1d of the mounting table 61.
Even if the thickness of the paper s23 is thin and the pusher 66 is able to overcome it, the protrusion 1116@e in the kerf @1, 61d, which is also low on the paper surface, Since the edge of the paper sheet 280 is pressed, the paper sheet 23 is pushed out by the pusher 6B without being pushed over.

Figures 7 to 9 show examples of actual vaginas of the present invention O and others corresponding to Figures 4 to 96, respectively. Figure, No. 9
#A is an enlarged view of the butsusha and the mounting position. When using Honko vagina example K, the mounting table 61 has a cut 1i as in the above embodiment.
Concave 1161. is continuous from the base end to the distal end without providing I61.

61f''iW&, and at the same time, the step-shaped protrusion 11@6dtlk can be inserted into the button 66 and engaged with the recesses 161e and 61f.

By doing this, the recess 61 is lower than the paper surface.

It is based on the above evidence that the paper 3128 is pushed out in the i1 stage without any pressure to get over the pusher 66 or the paper leaf 2st because the edge of the paper sheet 2 $0 on the loading table el is pushed. 'mIFll.

In addition, in this dormitory example, by providing a coordinating Yokozuna in each department, it is possible to accommodate a wide variety of paper sheets. First of all,
Due to the eccentricity of the rotary roller 61, when it is excited and adjusted, the gap between the lower end of the crusher 6 and the polishing table 61 is adjusted. In addition, the bracket 5 at the base of the platform 61
By moving 8 by 1, the angle of the platform @1 is adjusted, and by moving the guide sT up and down, the height of the platform @1 is adjusted. Furthermore, by adjusting the position of the tI tie bracket 62 to the maximum size of the paper 112$, loosening the set screw 55 of the block 51 and moving the support tube 3s, it is possible to accommodate changes in the dimensions of the paper 128. Fine adjustment can be made by fixing the block i1 to the support tube and then stretching the chiwaji shaft 54. Since the ti%7 flange 4S and the holder SO are connected through a long hole, By adjusting the phase in the circumferential direction, it is possible to finely adjust the operational timing between the pusher 6, the paper feed cylinder 21, and the pusher bin 31. Furthermore, the driven shaft 411 is
If 11 is overloaded, Ktj, cam follower 4s and bevel gear 4!0! ! As soon as the engagement 41 with the i part becomes disconnected and the engine idles, the switch plate 48 presses the contact point of the switch to stop the prime mover, thereby preventing the accident from spreading.

Above the loading platform, there is a button that is supported by a kite member that can be raised and lowered, and that reciprocates so as to advance at a slower speed in advance of the button shovel. By giving]
Since the impact on the paper sheet is alleviated, it is possible to prevent the occurrence of wrinkles caused by K, and the brush does not touch the paper surface and the paper surface is not damaged by its reciprocating movement. Since the table is stationary, the posture of the paper sheet when it is ejected is stabilized, so the quality of the product is significantly improved, and the operating speed can be increased.
It is possible to measure the improvement in production efficiency. In addition, the weight of the reciprocating member or the conventional device is significantly reduced, so the operating load is reduced, the speed can be increased, and the durability of the machine can be improved. (K) If a protrusion is provided at the lower end of the cutter and engaged with the mounting part, the cutter will cross over the sheet of paper on the cutting board and the sheet will tilt. The acceleration movement of the paper sheet is illuminating.
! Since the central part t1 of the sheet is not discharged to the conveyance table during the filtration process, it is possible to further improve the paper alignment performance.
