Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a continuous web of bileaf office paper folded in a zigzag pattern so that each leaf does not shift when passing through a high speed printing device. This invention relates to a sorting machine for bile office paper that is mutually locked.

Prior Art Prior to the advent of carbonless paper, almost all zigzag-folded, continuous web-like bileaf office paper consisted of a continuous web of carbon paper sandwiched between each office paper. ,
Also, to keep each leaf in place when used in high-speed printing equipment for bileaf office paper, bileaf paper often has integral locks of the perforation type along the side edges. ing. Conventional sorting machines are configured to remove and collect the carbon paper web during the sorting operation.
In most cases, removal and collection of the carbon paper web was done to facilitate sorting of each leaf.

More specifically, conventional sorting machines have a number of sorting stations arranged in series. Each separation station has a rotating refolding roller and a refolding section for separating one sheet of bile office paper from the remaining office paper. Generally, office paper is moved through a horizontal path adjacent to refolding rollers along a sorting station. The bile office papers were sorted one after another, and each time the lower office paper was guided downwards around the refolding rollers, dropped into the refolding section of the sorting station, and folded again into a zigzag shape. Become a gangster. Generally, the carbon paper web sandwiched between each leaf of bile office paper is also guided downwardly around the refolding rollers together with the separated office paper, and is rotatable adjacent to the refolding rollers. The material is wound onto a winding spindle. In this case, the carbon paper web serves to bring the separated office paper into strong contact with the refolding rollers.

In the sorting machine described in U.S. Pat. No. 3,857,557, the carbon paper web take-up spindle is located in a sorting station upstream of the refolding rollers, in which case the second roller The office paper being crimped onto refolding rollers and to be separated passes between these rollers. In this known sorting machine, the carbon paper web, rather than the office paper to be sorted, arrives at the sorting station in a lower position.
In this case, a transverse bar is provided above the take-up spindle adjacent to the horizontal path of the office paper to ensure separation of the carbon paper web and the office paper.

Problems to be Solved by the Present Invention Recently, the market share of carbonless office paper has been increasing. Although such carbonless biplane office paper has many advantages, it has been found that it is difficult to sort carbonless biplane office paper at high speeds with conventional sorting machines. This is because the sorting aid provided by the carbon paper web is no longer available. Additionally, the leaves of carbonless biplane office paper are often made from weaker paper than those of office paper sandwiched between carbon sheets, and are more likely to shift relative to each other as they pass through high-speed printing equipment. .
For this reason, the locking effect between each leaf has to be strengthened,
It is becoming more difficult to differentiate between cases. Practice has shown that conventional sorting machines cannot satisfactorily sort such highly locked carbonless office paper unless the operating speed is reduced. Even if the work speed is simply increased to neutral, a situation may arise in which the lock is not released and the office paper is carried away, posing a problem to the sorting work.

Furthermore, even when bileaf office paper sandwiched with carbon paper webs is used, known sorting machines cannot handle high paper if humidity, static electricity, lock strength, paper weight, etc. are not ideal. It is difficult to perform sorting work at high speed.

The object of the present invention is to improve a machine for sorting carbonless biplane office paper in the form of a continuous web folded in a zigzag pattern, so as to eliminate the above-mentioned drawbacks and to be able to carry out the sorting operation at high speed. It is to do so. Furthermore, the sorting machine can be manufactured at a relatively low cost, and the desired effect can be obtained simply by making improvements to the existing sorting machine.

Means for Solving the Problems The gist of the present invention, which has solved the above-mentioned problems, is to provide a bileaf office paper in the form of a continuous web folded in a zigzag pattern, in which each leaf is processed in an office paper processing equipment. In a bileaf office paper sorting machine that is mutually locked against slippage, a frame mechanism forming a number of sorting stations arranged in series and a predetermined path along the sorting station row allow a mechanism for moving bile office paper at a high speed, each sorting station being rotatably supported on a frame mechanism perpendicular to and in close proximity to the predetermined path, and each sorting station being rotatably supported within the sorting station; a roller that guides the office paper to be printed while contacting a part of its circumference; a mechanism that rotates the roller at a circumferential speed that is approximately equal to or slightly larger than the selected speed; a refolding section disposed downstream of and near the rollers with respect to the path of the rollers to receive the sorted office paper; The mechanism for assisting in the sorting is provided with a rod, the rod having at least a portion of its longitudinal direction perpendicular to the predetermined path and immediately adjacent to the path. a first wheel positioned on the rod and supported at one end by the frame mechanism, the rod being rotated by surface contact with the roller; and a wheel positioned on the circumferential surface of the roller. A second wheel that is in surface contact with the divided office paper and is rotatably driven by the first wheel via a coupling member is rotatably supported, and the roller and the second wheel are rotatably supported. the diameter of the first wheel is relative to the diameter of the second wheel such that the circumferential speed of the second wheel is greater than the selected speed of the sorted office paper passing between the It's a small thing.

Effects and effects of the present invention According to this configuration of the present invention, the first wheel and the second wheel are rotatably supported on the rod, and the first wheel and the second wheel are coupled to each other. The wheels rotate together, and the first wheel has a smaller diameter than the second wheel. Therefore, when sorting biplane office paper, the first wheel comes into surface contact with the roller, receives rotational force from this roller and rotates, and furthermore, the rotational force of the first wheel is transmitted to the second wheel. , will rotate together with the second wheel. However, since the first wheel has a smaller diameter than the second wheel, the circumferential speed of the second wheel will be faster than the circumferential speed of the first wheel, and this second wheel will have a smaller diameter than the second wheel. Since the paper is in surface contact with the rolled office paper, a tensile force is applied to the office paper so that the speed becomes faster than the speed at which the paper is guided downstream by the rollers, and the paper is guided downstream. The force also extends to the locking portion of the bile office paper, assisting in the unlocking action, and facilitating the sorting work.

In an advantageous embodiment of the invention, the second wheel between the ends of the rod is supported and
A third wheel is connected between the other end of the rod and the second wheel.
Although the third wheel is supported, the third wheel may be omitted. All wheels are rotated about the longitudinal axis of the rod and have relatively resilient outer circumferential surfaces.
A tube member is coaxially supported on the rod and is adapted to couple the wheels together for rotation therewith.

When the rod is in the first position, the longitudinal axis of the rod is approximately parallel to the axis of the refolding roller and the circumferential surface of the first wheel is in surface contact with the circumferential surface of the refolding roller. The circumferential speed of the first wheel is therefore approximately equal to the circumferential speed of the refolding rollers and slightly greater than the selected speed of the bile office paper. 2nd and 3rd
The circumferential surface of the wheel is in surface contact with the separated office paper of the refolding roller. The diameter of the first wheel driving the second and third wheels is slightly smaller than the diameter of the second and third wheels, so the circumferential speed of the second and third wheels is is greater than the circumferential speed of the wheel. Based on the difference between the circumferential speed of the second and third wheels and the speed of the separated office paper,
The second and third wheels exert additional force on the separated office paper on the refolding rollers. This additional force assists in the unlocking action and facilitates the sorting operation.

When the rod is in the second position, the longitudinal axis of the rod is at an angle to the axis of the refolding rollers and all wheels are in surface contact with the refolding rollers as well as with the separated office paper. Not yet. Therefore, in this state, no sorting assisting effect is produced. The bracket is
A mechanism is provided for loading the rod into a first position and elastically pressing the first, second and third wheels against the refolding roller and the separated office paper.

Practical tests have shown that the sorting machine according to the invention is capable of satisfactorily sorting locked continuous carbonless biplane office paper at high speeds. No problems occur even when working at maximum speed. The sorted office paper is neatly folded into a zigzag pattern within the refolding section. The sorting auxiliary device according to the invention can be easily attached to existing sorting machines.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, a sorting machine according to the invention is indicated generally at 10 and is used for sorting a continuous web of carbonless bileaf office paper 12 folded in a zigzag pattern. In the illustrated example, the bile office paper 12 is 4
It is made up of leaves put together. If the sorting aids are excluded, the sorting machine 10 is of ordinary construction and includes a base 14 and four walls 16 extending vertically upwardly and slightly to the left from the base. ing. A frame 18 connects the upper ends of the walls 16 to each other. base 1
4. The wall 16 and frame 18 form four sorting stations 20, 22, 24 and 26. A conventional housing 28 containing the motor and controls is mounted on the left end of the base 14. The housing 28 moves the bile paper 1 at various selected speeds through a generally horizontal path along the upper edges of the sorting stations 20-26.
It has a built-in tractor (not shown) that actively sends the 2. A control within housing 28 allows the operator to select one of a variety of selectable speeds. The housing 28 further has a support 30 projecting to the left, which supports
It supports zigzag-shaped packs of bile office paper that can be sorted.

The sorting stations 20 to 24 each have a carbon paper winding spindle 32, which is rotatably mounted on the frame 18. Further, the carbon paper bar 32a is attached to the wall 16.
The carbon paper take-up spindle 32 serves as a tension guide for the carbon paper web sorted at the sorting station, and the carbon paper take-up spindle 32 serves as a tension guide for the carbon paper web separated by the sorting station. Used to wind the web into rolls. A carbon paper take-up spindle 32 takes bile office paper 12 driven by a tractor within housing 28.
is rotated at a speed slightly greater than the selected speed.

At the sorting stations 20 to 26,
Office paper 34, 36, 3 on the bottom side each time
8 and 40 are judged sequentially. The sorted office papers 34 to 40 are bileaf office paper 1.
2 from a predetermined horizontal path downwardly within the sorting station and fall into refold sections 42, 44, 46 and 48 on base 14. The refolding sections 42-78 are of conventional construction, and the sorted office papers 34-40 are allowed to fall along the right side of the wall 16 and refolded into a zigzag pack.

Apart from the fact that the right sorting station 26 does not have a carbon paper take-up spindle 32 and a carbon paper bar 32a.
The construction and operation of all sorting stations 20-26 are identical. Therefore, in the following, only the sorting station 26 will be explained in detail.

As shown in FIGS. 1-4, the sorting station 26 has a refolding roller 50 that is disposed with its longitudinal axis in the plane of the wall 16 and has one end attached to the frame. It is rotatably supported within wall 18 and the other end is rotatably supported within the upper extension of wall 16 . The refolding roller 50 is attached to the housing 2
It is supported so that it can be rotated at a circumferential speed slightly higher than the speed of the bile office paper 12 driven by the tractor and feed roller in 8, and a number of vertical grooves 52 are formed on its outer peripheral surface 54. has been done. The office paper 40 to be separated at the sorting station 26 is guided downwardly around a portion of the outer circumferential surface 54 of the refolding roller 50 , in which case the vertical groove 52 is sufficiently spaced between the refolding roller 50 and the office paper 40 . Generates a strong contact force. As shown in FIG. 2, the width of the bile office paper 12 is smaller than the length of the refolding roller 50, and the bile paper 12 is positioned inside the left and right ends of the refolding roller 50.

One embodiment of a sorting aid according to the present invention is designated generally at 56 and includes a rigid straight shaft or rod 58. This rod 58
is rotatably supported at one end 60 by a bracket 62, and at the other end 60.
4 is not supported. To explain in more detail,
The end 60 of the rod 58 is secured within a transverse hole 66 formed in the pin 68 by a set screw 70 (FIG. 6). The bracket 62 has a base 72 and a
A screw 76 engages in a pair of slots 74 (FIG. 3).
A bracket 62 is fixed to the frame 18 by. Furthermore, the bracket 62 has a pair of arms 7.
8 and these arms 78 project from the plane of the base 72 in the same direction.
Both arms 78 have matching holes 80 into which the pins 68 are inserted. The diameter of hole 80 is slightly larger than the diameter of pin 68 so that pin 68 can easily pivot within hole 80. Axial movement of the pin 68 within the bore 80 is prevented by a flange 82 integral with one end of the pin and a snap ring 84 fitted onto the other end of the pin.

Bracket 62 is secured to frame 18 such that its arm 78 is located proximate refolding roller 50 and rod 58 has a first longitudinal axis substantially parallel to the longitudinal axis of refolding roller 50. It can be rotated to the position. As shown in FIG. 5, the rod 58 is in a second position in which its longitudinal axis is at an angle to the longitudinal axis of the refolding roller 50 and the other end 64 of the rod 58 is adjacent the frame 18. It can also be rotated.

A coil spring 86 is provided between bracket 62 and pin 68 to load rod 58 in its first position. In this case, Figures 6 and 7
As shown, one end of coil spring 86 is connected to arm 7 adjacent flange 82 of pin 68.
The other end of the coil spring 86 is attached to a screw 90 screwed into the flange 82 of the pin 68 . This causes the coil spring to load the rod 58 into the first position shown in FIGS. 2 and 4.

A tube 94 is supported on rod 58. The diameter of the tube 94 is slightly larger than the diameter of the rod, two spacer rings 96 and 9
8 are located between the tube and the rod at each end of the tube 94 to align the longitudinal axis of the tube with the longitudinal axis of the rod 58. Spacer rings 96 and 98 rotatably support tube 94 relative to the rod and are made of a material with extremely low frictional resistance.

As clearly shown in FIGS. 4 and 6, a wheel 100 is supported on the left end of the tube 94 and is secured to the tube 94 by a set screw 102. As shown in FIGS. Additionally, a wheel 104 is mounted on the right end of tube 94 and secured thereto by a similar set screw (not shown). Outer peripheral surface 106 of wheels 100 and 104
are made of a relatively resilient material to enhance engagement with rods or office paper.

The diameter of the outer circumferential surface 106 of the wheels 100 and 104 is the same as that of the log 58 shown in FIGS.
When the wheels 100 and 104 are in the position
The outer circumferential surface 106 of the refolding roller 50 is selected to be in surface contact with the outer circumferential surface of the refolding roller 50. More specifically, the wheel 104 and tube 94
is positioned on the rod 58 such that the outer circumferential surface 106 of the wheel 104 is in direct surface contact with the outer circumferential surface 54 of the refolding roller 50. The wheel 100, on the other hand, is arranged such that its outer peripheral surface 106 is in direct surface contact with the sorted office paper 40 on the refolding roller 50. 100 and 104 act to maintain surface contact with office paper 40 and refolding rollers 50.

As can be clearly seen from FIG.
It is touching 0. As shown in FIG. 3, the points of contact between the wheels 100 and 104 and the office paper 40 and the refolding roller 50 are horizontally tangential to the apex of the refolding roller 50, that is, the horizontal predetermined path of the bile office paper 12. , and a horizontal plane passing through the longitudinal axis of the refolding roller 50. By locating the contact point between the wheel 100 and the office paper 40 in this manner, the sorted office paper can be transferred to the lower refolding section 4.
properly guided towards 8.

It has been found that making the diameter of wheel 104 smaller than the diameter of wheel 100 significantly improves the sorting process. As already mentioned, the circumferential speed of the wheel 104 is the same as that of the refolding roller 50.
approximately equal to the circumferential velocity of Circumferential speed means, for example, the speed that a point on the outer circumferential surface 106 has in a direction perpendicular to the radius of the wheel 104.
Tube 94 connects wheels 100 and 104 so that the wheels rotate together at the same angular velocity. However, because wheel 100 has a larger diameter than wheel 104, the circumferential speed of wheel 100 is greater than the circumferential speed of wheel 104 and thus the speed of office paper 40.
As a result, the wheel 100 is the refolding roller 5
An additional force is applied to the office paper 40 above. With this additional force, the biplane office paper 12
This assists in releasing the locks that hold each office sheet in place as it passes through a high speed printing device, such as a high speed impact printer.

Experiments have shown that if the diameter of the wheel 104 is 5 to 20% smaller than the diameter of the wheel 100, the paper sheets 34 to 40 can be sorted without any trouble even when the sorter 10 is set to its maximum speed. A separation operation and a clean refolding within the refolding sections 42-48 takes place. In this case, the best effect is obtained by making the diameter of wheel 104 15% smaller than the diameter of wheel 100.

A second embodiment of a sorting aid according to the present invention is shown at 114 in FIGS. 8-11. This sorting auxiliary device 114 has substantially the same structure and operation as the sorting auxiliary device 56, except for the points described below.

The end 60 of the rod 58 used in the sorting aid 114 is pivotably supported by the bracket 116. However, it may also be supported by a bracket 62. Similarly, it is also possible to use brackets 116 in the sorting aid 56.

The major difference between the sorting auxiliary devices 56 and 114 is that the latter has a different smell from the first and second wheels 1
04 and 100, a third wheel 118 is provided. This wheel 118
has the same structure as wheels 100 and 104.
In the sorting auxiliary device 114, the rod 58
And the tube 94 is made longer than the rod 58 in the sorting auxiliary device 56, and the nut 1
20 is coupled to the rod end 64 to maintain the rod and tube in their proper assembled condition.

The third wheel 118 is the wheel 100 and 1
It is attached to the tube 94 so that it rotates with the tube 94 like the 04, ie all three wheels rotate together. Wheel 118 is located at end 64 of rod 58 and second wheel 100 is located between third wheel 118 and first wheel 104. Sorting aid device 56
Wheels 100, 104, 11 as in
8 and the office paper 40 and refolding roller 50 are located between the horizontal plane passing through the longitudinal axis of the refolding roller 50. Rod 58
The length of the tube 94 and the arrangement position of the wheels 100 and 118 along the tube 94 are such that the contact point between the outer circumferential surface 106 of the wheels 100 and 118 and the office paper 40 is approximately 1/2 between the both side edges 108 of the office paper 40. It is chosen to be located at 4 and 3/4.

Three wheels instead of two (1
(one driving wheel and two driven wheels), the sorting aid 114
can be used for bi-leaf office paper of various widths as well as bi-leaf office paper that is split along a central longitudinal line into two webs. Experiments have shown that the outer circumferential surface of the refolding roller 50 is slightly eccentric, causing a momentary loss of pull against the office paper, which impedes the sorting process.
Using two 118s largely solves this problem and increases the pulling force.

9-11, the bracket 116 includes a plastic pivot member 122 having a finger portion 126 projecting from a cylindrical portion 124. As best seen in FIGS. The cylindrical portion 124 has a circular end face 130 with the end 60 of the rod 58 being centrally fixed to and projecting from the end face 130 at right angles. First wheel 104 is secured to tube 94 adjacent end face 130 .

The bracket 116 has a support plate 132, also made of plastic, which comprises a generally rectangular base 133, a centrally located spring-loaded finger portion 134, and a support plate 132, also made of plastic.
two flanges 13 protruding from 3 to one side;
It consists of 6.138.

A pin 146 extends through the outer ends of the flanges 136 and 138 and the pivot member 122 such that the pivot member 122 is centered about the axis of the pin in a plane perpendicular to the axis of the pin 146. Can rotate freely. A spacer ring 148 is supported on pin 146 between pivot member 122 and flanges 136 and 138. This spacer ring may be molded integrally with the pivot member 122. A coil spring 150 is wound around each spacer ring 148, and the coil spring 150 is coaxial with the pin 146. Each coil spring 1
One end of 50 is attached to support plate 132 and the other end is attached to pivot member 122. The coil spring 150 moves the pivot member 12 in a clockwise direction as viewed in FIGS. 9 and 10.
As a result, the wheel 104 and the wheels 100 and 118 are elastically pressed against the outer peripheral surface of the refolding roller 50 and the separated office paper 40, as shown in FIG. be done. An advantage of using coil spring 150 is that the loading force on pivot member 122 can be easily adjusted. For this purpose, the pivoting member 122 has on its side facing the flanges 136 and 138 a series of holes 151 spaced apart along an arc centered on the axis of the pin 146. These holes 151 are adapted to receive the other end of the coil spring 150, and by selecting the holes 151, the load force can be adjusted.

As can be clearly seen in FIGS. 10 and 11, the spring-action finger portion 134 of the braget 116 is aligned with the plane of the base 133 and the pin 14.
6 and between flanges 136 and 138. One end 152 of the finger portion 134 is integrally connected to the base 133. The remaining section 154 of finger portion 134 has a smoothly curved intermediate section 156 with a pin extending toward 146. Category 154
overlaps a slot 158 formed in the center of base 133, the dimensions of slot 158 being somewhat larger than section 154 such that section 154 is located within the slot relative to slot 158. Can move.

As shown in FIG. 10, the spring-acting finger portion 134, which is normally positioned in a plane substantially parallel to the base 133, resists the spring force and pivots around the end 152. The lever can be moved from its normal position. Rotating member 122
The finger portion 126 is used to manually pivot the sorting aid 114 about a pin 146 from a first position (working position) shown in FIG. 8 to a second position (rest position) adjacent to the frame 18. When the finger portion 134 is moved, the finger portion 134 passes through the curved top portion of the finger portion 134 while contacting the intermediate portion 156. This engagement between the finger portions 134 and 126 causes the sorting aid 114 to remain in the second position, and in order to return to the first position, the intermediate portion 156 must be pushed in by the finger portion 126. It won't happen.

Practice has shown that the diameter of wheel 104 is 5-20% smaller than the diameter of wheel 100 and that the diameter of wheel 100 is smaller than the diameter of wheel 118.
5 to 20% smaller than the diameter of the paper, the sorting machine 10 and its maximum speed will work without any problem, and the office papers 34 to 40 will be separated satisfactorily, and the zigzag-shaped packs will be separated within the refolding sections 42 to 48. Folds neatly.

Furthermore, a sorting machine with a sorting aid 56 or 114 also solves other problems. That is, by using the wheel 100 or the wheels 100 and 118 that drive the office paper downward relative to the refolding roller 50, a downstream tensile force is always applied to the office paper, so that conventional static electricity This makes it difficult for the office paper to separate from each other, and some of the office paper is carried to the next station, preventing a constant flow downstream.
This also solves the problem that has hindered refolding.

While the sorting machine 10 is working, the bile office paper 1
2 is placed on a support rack 30 and threaded through the tractor within the housing 28. The bile office paper 12 may be a regular zigzag refolded continuous web-like carbonless bile odor paper;
The sorting machine 10 shown in the figure cannot process multi-leaf office paper of five or more sheets. (For bileaf office papers with five or more leaves, the number of sorting stations must be five or more.) The leading edges of bileaf paper 12 should be refolded by hand at each sorting station 20 to 26. It is pulled along a horizontal predetermined path tangent to the apex of the roller 50. Each sorting station 20~
At 26, the leading edge of the office paper, in each case on the lower side, is manually torn off and the refolding rollers 50 and wheels 100 or wheels 100 and 1 of the sorting station are removed.
It passes between 18 and 18. Compound office paper 12 is the first
Once positioned as shown, the sorter 10 can be started in the normal manner and operated at full speed until the sorting of the bile paper 12 is completed. If it is desired to operate without the use of sorting aids 56 and 114, for example when a carbon paper web is sandwiched between each sheet of bile office paper, each rod 58 can be from one position to a second position.

However, it is also possible to use the sorting aid 56 or 114 according to the invention for carbon paper webs or interleaved bile office paper, thereby improving the sorting action. This is because the sorting auxiliary device according to the present invention applies a driving force and a guiding force to the office paper.

Various modifications can be made to the sorting machine 10 as well as the sorting auxiliary device 56 or 114 within the scope of the invention. For example, the rod 58 could be supported to the frame 30 by means other than brackets 62 or 116, and the rod 58 could be supported by means other than brackets 62 or 116.
The end 60 of 8 can be pivoted between the first and second positions by other means. Similarly, the rod 58 can also be loaded by other means. Outer peripheral surface 1 of wheels 100, 104, 118
06 does not necessarily have to be elastic. In determining the diameter of the wheels, the best results are theoretically obtained if the outer circumferential surfaces of all wheels form one common conical surface. However, in practice, the outer peripheral surface is made almost cylindrical,
It is preferable to maximize the contact area between the wheel circumferential surface and the office paper and refolding roller circumferential surfaces. In the sorting aid 114, the wheels 100 and 118 can have the same diameter, but in that case a universal joint may be inserted into the rod portion between the wheels, or the outer peripheral surface 106 of the wheel may be made extremely elastic. must be made from suitable materials. Finally, wheel 100 can also be omitted if wheels 100 and/or 118 are driven by separate means.
