Abstract

PURPOSE:To position both horizontal and inclining orientations without exchange of parts and regulation even if the height of a machine is varied, by a method wherein the expandable coupling leg of the support leg of a sheet discharge conveyor is adapted to be relatively slanted on both sides of a line extending normal to a floor surface when the conveyor is in each of a horizontal and an inclining orientation state. CONSTITUTION:When a chopper device is in use, a sheet discharge conveyor 13 is lifted togetherwith a leg 45 to engage a stay 52 with a bent part 54a. In which case, if regulation is effected so that a coupling leg 55 is grounded when the conveyor 13 is brought to a horizontal state, there is no need for further regulation. A chopper folded leaf is carried over to conveyors 13 and 12 to convey it to a stacker. Further, when a device is shifted to a parallel double folding process, a coupling lever 50 is lifted to rotate a conveyor 13, the grounding side of a support lever 46 is moved from position, shown by a chain line, to position shown by a solid line. When an inclining angle theta1 of a coupling leg 55 becomes equal to an angle theta2, the link motion of a leg 45 is stopped, the start end of the conveyor 13 corresponds to the terminal end of a conveyor 14 in a manner that the start end is positioned flush with the terminal end. This causes carrying over of the parallel double folded leaf, in order, to the conveyors 14, 13, and 12 to accumulate them on the stacker.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper ejecting device for ejecting signatures that have been dried, cooled, and recut after being printed in a rolled paper rotary printing press.

Printing is performed by continuously feeding out a rolled web.
J:l! The roll-fed paper rotary printing press is equipped with a folding machine that cuts or folds the web, which has been dried and cooled after printing, into predetermined dimensions. The folding methods using this folding machine are generally a former folding method in which the web is folded in half in the direction of the eaves, a cylinder folding method in which the web is cut and folded in half in a direction perpendicular to the former folding sheet, and a cylinder folding method in which the web is cut and folded in half in a direction perpendicular to the former folding sheet. Chopper folding and chiseling, which fold a book in half in a direction perpendicular to cylinder folding, are used, either or all of which are selected and used depending on the specifications of the signature. In recent years, with the diversification of printing, even more types of signatures have been required, and in order to make it possible to perform so-called parallel double folding, which is generally called parallel folding, cylinder folding is performed twice. A folding machine with an increased number of folds has been developed and is now widely used.

FIG. 1 is a schematic side view showing a paper ejecting device of a conventional folding machine that makes it possible to fold the web two times in parallel. Conveyor belts 2 and 3 are provided with conveyor belts 2 and 3 that are stretched vertically in parallel in the width direction and run in the direction shown by arrow A in the figure. An impeller 4 that rotates in the direction shown by arrow B is mounted on a shaft 1, and a chopper 5 and upper and lower scraping rollers 6 are arranged on the conveyance path of the conveyor belt 2°3.
A chopper device I is provided, and a pair of impellers 8 are mounted below the chopper device I so that the axial direction thereof is orthogonal to the impeller 4. On the other hand, a second gripping cylinder 1 is located below the first gripping cylinder 9 to which the first portion f':4 of the conveyor belt 2 is attached.

In such a conventional paper ejection conveyor 1 (!, l, ;), a central paper ejection conveyor 13kl, a pair of left and right 11115 pivoted thereto, and legs 15 are connected to the Iio conveyor 13. The leg 15 is supported on the floor 17 by a connecting lever 16.The connection 4j between the leg 15 and the F''i lever 16 is also constructed by connecting the left and right legs 15 with stays 18 in an H-shape 1 (connecting this Connect the stay 18 to the long hole 1 of the lever 16
9 and 11), and the paper discharge conveyor 13
When the stay 18 is supported by the leg 15 at the chopper folding 9 paper ejection position shown in the actual test, the stay 18 is inserted under the elongated hole 19<:jn M1
Engage with the curved portion and also move the paper discharge conveyor 13 to Zheng's f;
! When supporting the leg 15 at the parallel 2-diffraction sheet discharge position f+it, the stay 18 is regulated by the upper end of the elongated hole 19, and the position of the stay 18, the position of the elongated hole 19, and the length. In this case, the sheet discharge conveyor 13 is horizontal at the solid line position 11T, and its starting end is at the chain line position 11T.
It is set to correspond correctly to the end of 4.

However, the height of the printing press from the floor must vary depending on each printing factory depending on the condition of the foundation as a vibration-proofing measure and the relative position with the trolley that discharges signatures, so generally the frame 20 and Raising platform 2 between floor surface 11
The machine is leveled and the height is adjusted by interposing the machine and expanding and contracting its height. Therefore, assuming that there is no raising platform 9.1, and setting J≧Size of the elongated hole 19,
The paper discharge conveyor 13 has legs 15 supported on the floor 17.
Because the starting end of
This joint leg 22 is expanded and contracted according to the height of 41 to determine the position of the paper discharge conveyor 130.

Clause “tl, ・The trouble of having to return 11]] 1
However, it is actually difficult for the manufacturer to manufacture the connecting lever 16 for various machine heights or machine the elongated hole 19 on-site.

The tree 413ri is potted at the front point as shown in the figure below, and is used as a support member for the paper delivery conveyor, which is selectively positioned and fixed in the horizontal (stand) and tilted positions using folded branches. The contact jlh (l'!Q ?iia part is fixed with a joint leg for grounding that can be freely extended and fixed, and the joint leg that goes down to J is mutually fixed on both sides of the vertical ρ? with respect to the floor surface. By setting the angle of inclination of the flY legs relative to the legs so that they are inclined at the same angle in the opposite direction, the horizontal and inclined postures of the paper delivery conveyor can be maintained regardless of the change in machine height due to the condition of 1 step. To provide a paper discharge device for a web-fed rotary printing press that enables accurate positioning without replacing parts or making adjustments every time a posture is changed, thereby improving work efficiency and reducing labor.

2 to 4 show embodiments of the paper discharging device according to the present invention, FIG. 2 is a schematic side view of the paper discharging device shown corresponding to FIG. 1, and FIG. 3 is the G of FIG. 2. Enlarged plan view, Figure 4 is the 3rd
FIG. 6 is an enlarged side view of the vicinity of the paper discharge conveyor and the legs, and an enlarged side view of the connecting legs.

The same reference numerals as in Fig. 1 in M indicate the tii.
Since the configurations are the same, a detailed explanation will be omitted, and the configuration of the switching equipment of the sheet discharge conveyors 12, 13, 14 and the third sheet discharge conveyor 13 will be described below. A first paper delivery conveyor 14 for conveying two parallel 2-fold sheets is located below the impeller 11 and stretched horizontally, and a second paper delivery conveyor 14 is placed diagonally above in front of the impeller 11. The conveyor 12 is stretched slightly inclined. This second paper discharge conveyor 12 includes a pair of left and right conveyor frames 32 supported by brackets 31 hanging from the front end of the frame 20. 14fl
A plurality of conveyor tapes 34 are stretched in parallel in the axial direction between the tape rows 233 that are axially suspended between the tape s and the end section 1. 35 is a gear for driving the rotation of the tape roller 330, and 36 is a sprocket for rotating the paper discharge conveyor 14. The third paper discharge conveyor 13 has a pair of left and right conveyor frames, 3T, which are loosely attached to the tape roller 33.
Between the tape roller 38 and the tape roller 33, which are axially mounted at the beginning 1h, a plurality of conveyor tapes 39 are arranged in parallel in the axial direction with a different phase from the conveyor tape 34. It is strung up. Reference numeral 40 denotes a tension pulley for tensioning the conveying tape 39, and although not shown, it is provided for each conveying tape 39.
The conveyor tape 34 is also provided. The front and rear two cylinders of the left and right conveyor frames 37 are connected by a stay 41, and one end of the front stay 41 is fitted with a handle 42 for operating the conveyor. At an adjacent position, the L1 leg support shaft 43 is prevented from moving in the axial direction by a collar 44, and is pivotally supported by the left and right conveyor frames 3T. A leg support rod 46 indicated by reference numeral 45 is prevented from coming off by a collar 47 and is loosely mounted.A support rod 49 that supports the bracket 48 for the tension rod 48 is supported at both ends by a conveyor frame 47. Sail
A pair of left and right connecting levers 50 formed in a rectangular shape are connected to the protruding end of the support 1f1149 from the frame 47 by a stay 51 in an H-shape, and a collar 52 connects the support shaft 49. It is being played with and prevented from escaping. The left and right support rods 46 have their center and lower end portions connected by stays 52 and 53, and the portion of the center stay 52 adjacent to the support rod 46 is inserted into a long hole 54, which will be described later, provided in the support rod 46. They are slidably fitted. Further, at the ground contact side ends of the left and right support rods 46, a joint leg 55 formed in a U-shape is extendable and retractable by two bolts 56 at an angle θ set in section 1. Freely [[! −
The angle of inclination does not change even if the connecting leg 55 is expanded or contracted because it is guided by two bolts 56. Then, by grounding the legs 55 with t41ζ, the entire legs 45 support the paper discharge conveyor 13 against the floor surface 17, and the elongated hole is bent near the )'j+i section on one side. This bent portion 54a
By engaging the stay 52 and touching the joint leg 55 to the ground, the joint leg 55 is extended so that the paper discharge conveyor 13 is in a horizontal position as shown by the chain line in FIG. [BajsaJ], I'm here. Also, when the stay 52 touches the other part 11 of the elongated hole 54 (when the conveyor 13 is rotated, the near foot 55 "sticks" to the solid line position). Discharge χ41. The conveyor 13 is inclined, and its starting end corresponds to the terminal end of the first paper discharging conveyor 14. At this time, the inclination angle θ is adjusted so that both conveyors 13 and 14 correspond to the same height. I have set it. Zunawaji, Tsujiashi 55

'Lii〉 is inclined in the opposite direction on both sides of the vertical shaft 57 with respect to the floor surface 1T, and forms an angle θ1 with the floor surface 1T. The inclination angle 0 is set so that the angle θ2 is the angle θ2 and the angle θ′γ.

Further, the I/stop hole 54 is extended from the bent portion 54a at a position 1 indicated by 5/Ib, and the stay 52 is inserted into this end 5.
By rotating the paper discharge conveyor 13 until it comes into contact with the paper conveyor 4b, the joint leg 55 separates from the floor surface 17, and the support rod 46 can rotate around the floor surface 1T. By rotating the paper conveyor 13 and the legs 45 together in the clockwise direction in FIG. 4, the paper discharge conveyor 13 can be placed in a vertical position.

The operation of the paper ejecting device configured as above will be explained. When using the chopper device 7) - Grasp the handle 42 and lift the paper discharge conveyor 13 together with the legs 45.
2 is engaged with the bent portion 54a of the elongated hole 54. In this case, the machine is initially installed so that the joint feet 55 touch the ground when the paper discharge conveyor 13 is exactly horizontal.
If you adjust the expansion and contraction, there is no need to adjust it later.

By doing this, the signatures that have been cylinder-folded and then chopper-folded are discharged onto the sheet discharge conveyor 13 and conveyed by the impeller 8, and then taken over by the sheet discharge conveyor 12 and conveyed to the stacker.

When changing the folding method of signatures to parallel double eve 1),
When the connecting lever 50 is slightly lifted by holding the handle 42 in place, the stay 52 and the bent portion 54a are engaged with each other and the conveyor 13 is rotated clockwise. The stay 52 is then slid within the elongated hole 54 to rotate the paper discharge conveyor 13. At this time, the support rod 46 moves two times from the chain line 1 position fi7c to the solid line position F' so with the entire leg 45 making a link movement. Then, when the inclination angle θ1 of the t() 1st leg 55 becomes equal to the inclination angle θ2, the stay 52 moves into the elongated hole 54 (1, b
The link movement of the leg 45 stops when it comes into contact with j>ilj.

At this time, the starting end of the paper discharge conveyor 13 corresponds to the terminal end of the paper discharge conveyor 14 at exactly the same level by setting the angle θ on the desk and the length of each member. By doing this, the signatures folded twice in parallel are discharged and conveyed by the impeller 11 to the sheet discharge conveyor 14''2, and then taken over and conveyed to the sheet discharge conveyor 13゜12, after which they are conveyed to the stacker). 1 piled up. In addition, when the inclination of the paper discharge conveyor 13 is steep as shown in the figure, an independent cassette conveyor is generally placed on the PL paper conveyor 13, and both conveyors sandwich and convey the signatures. and joint leg 55
i! Clause 'd' requires that the machine be installed only once at the beginning (d:), and there is no need for the h1 value each time the posture of the sheet discharge conveyor 13 is changed.

Furthermore, since the height of the machine relative to the floor 17 varies depending on each factory, if the various parts of the legs 45 are shared by each factory, the installation will be carried out with the joint legs 55 grounded and the stays 55
2 and the bent portion 54a are engaged with each other.
It is necessary to adjust the expansion and contraction of the joint leg 55 so that the angle 3 is horizontal, but if you do it only once, the angles θ1 and θ2
Since the condition that and is the same every time the paper discharge conveyor 13 is switched does not change regardless of changes in the height of the machine, there is no need to adjust the joint leg 55 every time the paper discharge conveyor 13 is switched. Note that when it is necessary to work below the chopper device 1 for paper packing on the origami section side or adjustment of the zero feed tape 34, 39, the stay 52 is connected to the end 54b of the elongated hole 54. After lifting the handle 42 until it is engaged, hold the handle 42 and turn the paper delivery conveyor 13 and the legs 45 as one body in the 5-clock direction while urging the support rod 46 clockwise. If you let
Leg 45 contact! Since the + portion does not touch the floor surface 1γ, work below the ridge chopper i device 1 is facilitated by placing the paper discharge conveyor 13 under the η force.

As is clear from the following, according to the present invention, when the wrapping paper j11) is placed on the output sheet 2 of the paper roll j11), the folding type is different from the folding type. Toni■ Oblique view〈:)
