Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention relates to a method for perforating vertically stacked plain paper (hereinafter referred to as a stack) to form holes spaced apart along the lower periphery of the stack. This paper relates to a new and improved paper punch used for More specifically, the present invention removes a bundle of paper from a stack, consisting of any number of sheets up to the number that the punch can handle, punches each bundle separately, and then removes and places the sheets in a tray. It is characterized by the ability to drain, drill and collect the entire stack.

(b) Conventional technology Various types of motor-driven punches have been used in the past.

However, in most such punches, the paper sheets are stacked horizontally (rather than stacked vertically as in the present invention). Furthermore, the paper for one process (hereinafter referred to as a batch) is cut into the top of the stack using a knife or other means, lifted and taken out, and fed into the punch mechanism.

Such punches are generally not a desirable drilling means due to the cost and many problems associated with their operation.

Existing punch machines typically have difficulty punching paper that is mixed in thickness (e.g., cover and body pages) or folded into signatures.

(C) Summary of the Invention The present invention is characterized in that papers are stacked vertically and that a single batch of paper is taken out and perforated without using a knife.

As mentioned above, one of the features of the present invention is that the paper is handled in vertical stacks. The stack is rocked to remove one batch of paper of a thickness that can be accommodated by the punch. Therefore, a batch of paper can be removed from the stack without using any cutlery.

After taking out one batch, the jaw grips the top edge of the batch, lifts it up, and inserts it into the slot.Then, the batch is lowered into the slot until the bottom edge of the plain paper is seated on the bottom of the punch. 0 Then, the punch pin reciprocates in the horizontal direction, moving 1 along the bottom edge of the plain paper.
Drill a series of holes.

During the next working cycle of the punching machine, where a second batch of paper is removed while the first batch is being punched, one set of jaws grips the first batch and another set of jaws grips the second batch. set and each batch is lifted upwards and backwards respectively. The first batch is inserted into a slide which moves the perforated paper to an output tray while the second batch is lowered into the punch.

In the preferred embodiment described below, timing of the sequence of actuation cycles is accomplished by a timing shaft comprising a plurality of cams. However, it will be appreciated that other means may be used to time the actuation cycles.

The operating cycle is repeated until the stack is fully perforated.

One of the features of the invention is that paper signatures of the type used for commercial book printing can be perforated and each signature handled in the same manner as a batch.

Thus, the present invention can eliminate steps that conventionally required complicated manual operations.

Another object of the invention is that, in each of the several drawings, like reference numerals refer to the accompanying drawings in which like parts are shown.
It will be understood by reading the detailed description below.

(D) Embodiment and Immunization Δ Adjustment The punch machine described below functions to punch holes along the periphery of the stack 49. The dimensions and spacing of the perforations can vary widely. However, in a preferred embodiment, the holes are for binding plain paper using binding strips such as those described in U.S. Pat. No. 4,369,013.

The machine frame includes a base 51, and a side portion 52R from this base 51.
and 52L extend upward. For convenience of explanation of this machine, the front of the machine is shown as viewed from the left side of FIG. The right side of the machine is the right side in Figure 1, and the left side of the machine is the left side in Figure 1.6 The expression ``forward J'' used when describing the mechanism or the path of paper movement refers to movement from the front to the rear. and the expression "retreat" shall mean movement in the opposite direction.

A casing 53 surrounds the machine frame, and the main motor that rotates the drive pulley 57 is supported by the machine frame, which is provided with a door 54 that opens forward. This drive pulley 57 drives a driven pulley 58 via a belt 59. The driven pulley 58 is connected to the base 5
1 rotates a timing shaft 61 extending horizontally at right angles to the machine, close to the rear of the machine, above 9. In the embodiment shown and described below, the timing of the mechanism is This is done by a series of attached cams. The tappets of this cam pivot various levers described below. However, it will be appreciated that it is also possible to use other timing means, such as electronic timing means, and furthermore, instead of cams and levers, solenoid valves, electric motors, pneumatic or hydraulic means, etc. can be used to perform various mechanical functions on the parts illustrated and described.

Eight cams are timed and controlled by the activation shaft 61. A first cam 62 advances the paper bushing support. Second
Cam 63 starts the single cycle punch motor and stops the motor when the gripping mechanism reaches its upper end of operation. A third cam 84 controls the forward and rearward movement of the lever that advances the paper. 4th cam 65
opens and closes the jaws attached to the lever and grips the batch taken out. The fifth cam 66 functions to lift the lever. The sixth cam 67 controls the movement of the rotating paper guide. The seventh cam 68 controls the movement of the paper retractor, and the eighth cam 69 controls the paper bushing support retractor. The various functions performed by the cam will now be described in detail.

Mu! ! 3. A drawer 71 is attached to the inside of the door 54.
This drawer 71 is normally arranged vertically and has at its lower edge a rearwardly extending support 72 for the bottom of the stack. Also provided is a stack side support 75 fixed to the drawer 71. A paper advancing device 73 (hereinafter referred to as an advancer) is provided within the drawer 1, and the advancer 73 is mounted on a pivot shaft 74 at approximately the midpoint of its height. The pivot 74 extends horizontally perpendicular to the drawer 71 and extends outwardly on one side into a slot 77 in the slide extension 76 . The slide extension 76 is fixed to a door slide 78.

On the other hand, this slide 78 is fitted into a static field slide 79 fixed to the side parts 52R and 52L. Hinge 8
1 hinges the drawer 71 to the slide 78.

A latch 82 locks the drawer 71 to the casing 53.

To load the stack 49 into the drawer 1, the latch 82 is released, the drawer 71 is pulled forward, and the slide 78 is slid within the slide 79. drawer 71
When opened, it tilts upward and forward to the position shown in Figure 11. The advancer 73 pivots about a pivot 74 in parallel to the drawer 71.

When the stack 49 is seated in the appropriate position on the side supports 75 and the bottom surface 72, the drawer 71 is tilted into an upright position and pushed rearward into the receptor 85.
On the front side of the machine there is a vertical receptor back 86 that restricts the forward movement of the stack 49, and also supports 72.
There is also a horizontal receptor floor 87 on which the receptors slide. To the left of the floor 87 is a fixed support 88.

On the right side of the floor 87 there is a movable right-hand support 89, the rear end 91 of which supports 89 for each batch 1 to be drilled.
24 is spaced in front of the bag 86 by a distance that determines the amount of paper to be removed from the stack 49. The removal of batches 124 continues until the entire stack 49 has been perforated (eg, Figure 25), at which point the machine's operating cycle is stopped and the drawer 71 is opened.

An advancer lever 96 pivoting about a horizontal transverse pivot 97 is mounted on one side of the machine. A first horizontal link 98 and an adjacent parallel second horizontal link 99 reciprocate in the machine's longitudinal direction at the bottom right hand side. Link 9
9 is formed with a pair of horizontal slots 101 spaced apart in the vertical direction. A pin 102 secured to the link 98 extends into the slot 101, and the pin 102 is secured to the link 98.
99 is biased in the opposite direction by spring 103. By providing the slot 101 and using the bin 102, depending on the amount of paper in the stack 49, the lever 9
6 movements can be adjusted. The link 99 has an upwardly extending portion 104 having a roller 106 that presses against the cam 62.
It is equipped with

In this way, when the stack starts to swing, the stack 49 is moved by the advancer 73 by the cam 62, and the stack 49
Moved backwards relative to 6.

A shaft 111 rotated by a punch motor extends perpendicular to the machine from the front corner of the bottom of the machine, as will be explained below. A swing cam 112, shown as a triangular member, is provided at the right end of the shaft 111, with which a follower 113 engages.
The follower 113 is held in a engaged state by a spring 114. Follower 112 includes an upward extension 116 . This extension 116 is pivotally connected to an arm 117 extending from a longitudinal shaft 118 fitted in a row block 119 in the upper right corner of the machine. axis 118
The extension portion 112 is fitted into the right support 89. Therefore, when the shaft 111 rotates, the stack 49 is held against the receptor back 86 by a controlled pressing force.
sways. The right side support 89 is higher than the left side support 88, and the terminal 91 of the support 89 is located at a distance in front of the receptor back 86, so that the support 89 is taken out from the stack 49 by the above rocking as shown in FIG. The predetermined amount of paper pivots down and to the right. The upper edge of the stack 49 is swung between the terminal 91 and the receptor block 86,
It will be in a higher position than the batch rotated downward (see Figure 9).

A stabilizer 123 is positioned proximate the top right corner of the receptor bag 86 to prevent the separated batch from falling forward.

On the left side near the rear of the machine, while the pulley 58 is rotating,
Tappet 1 to which the seventh cam 68 engages in a specific stage
There are 26. The tappet 126 is connected by a pivot 127.
It is pivoted to the left side 52L. The other end of the tappet 126 is
Pivotably connected to link 128 and link 12
8 is pivotally mounted to a crank 129 extending from a transverse horizontal shaft 131 proximate the top front corner of the machine. axis 131
On the opposite side, that is, on the right side, there is an arm 13 that contacts the crank 134 pivotally connected to the side portion 52R and pushes it forward.
A zero paper retractor bin 133, numbered 2, extends above the crank 134. The height of the bin 133 is lower than the height of the stack 49 that has not been tilted into the stabilizer 123, but is above the position of the stabilizer 123 and the first batch held therein. Thus, as the cam 68 rotates, the bin 133 moves forward, pushing the stack not in the gauge 123 forward against the return spring 136.

Link 138 has an elongated lost motion throat 139 formed therein. The pin 141 of the arm 132 fits into this slot 139. Figures 15 to 18
See the figure, after sufficient time has elapsed for the bin 133 to retract all papers in the upper right corner that have not been removed into the stabilizer 123, the bin 141 reaches the end of the slot 139 and the rocker arm Pivot 142,
The link 143 is lifted, thereby pivoting the crank 144 and shaft 146 connected thereto. The shaft 146 is fitted into the bellow block 147, and the arm 1 is attached to the other end.
48, and the outer end of this arm 148 has a finger 1.
49 is a provision. Thus, after the paper is retracted, finger 149 falls between the batch 124 and the rest of the stack approximately midway between the sides of the stack. Therefore, the stack 49 is restrained in the retracted position until the removed paper batch 124 is gripped by the jaws described below and ejected from the receptor 85.

An arm 163 pivotally attached to the inside of the right side 52L and left side 52R of the machine has a U link 167 with the pivot 74 at the bottom of the gap. The spring 80 of the arm 123 is connected to the pivot 7
4 and advancer 73 are biased rearward.

However, bin 133 and finger 149
When 9 is moved forward, spring 80 is deflected, allowing such a backward movement.

When the stack 49 is completely depleted, switch 246 opens, energizing the timer and activating the punch until the last batch 124 is punched and ejected. switch 2
35 within a predetermined period of time (for example, 3 seconds), the batch 124
If the solenoid valve 257 (see FIG. 5) on the left side of the machine is not sensed to be ejected from the machine, the solenoid valve 257 (see FIG. 5) is energized and presses its plunger 252.

The link 253 attached to the plunger 252 is connected to the lever 1
58 downward. The front end of the lever 158 is pivotally connected to a link 159, and the front end of the link 159 is pivotally connected to a transverse horizontal pivot 161. A side portion 52L is attached to the rear end of the lever 158 by a follower 153 and a pivot 157.
A cam 152 is formed which engages with a shoulder portion 155 at the upper end of the lever which is pivotally connected to the lever. The lower end of the lever 156 has a follower 154 that is normally outside the cam 69 trajectory of the pulley 58.

When the solenoid valve 251 is energized, the follower 154 descends into the trajectory of the cam 69. Cam 69 pushes follower 156 clockwise, follower 153 engages shoulder 155 and forces lever 158 forward, causing link 159 and shaft 161 to pivot clockwise. Arm 15 on one side of the machine
The outer end of the 9 outer end is pivotally connected to a link 162, which in turn is pivotally connected to a retractor arm 163, and the lower end of this arm 163 is connected to the side 52L by a pivot 164.

can be connected to the arm 163 provided inside the member 52.

Therefore, the arm 163 presses the shaft 74 in an order that matches the timing of the rotation of the timing shaft 61, and the advancer 74
3 is retracted, thus allowing retraction movement of pin 133 and providing sufficient space to force finger 149 into the space between stack 49 and the removed batch.

paper! Before further explaining the operation of the arms 178, 179, it is desirable to explain the vertical members that guide the removed batch of paper. For this purpose, a punch slot 207 is provided at a position spaced rearward from the receiver bag 86.

A front guide member 201 having a forwardly bent upper end contacting the upper end of block 86 forms the front side of slot 207 . Behind this guide member 201 is a rear guide 203 of the punch slot. As explained below, batch 124, positioned in the slot between guides 201-203, is directed into the punch and then lifted out of the punch for ejection. Behind the guide 203 is an ejection slot 208 . f! A rear guide 20 having an upper end 20B bent in the direction and a swing guide 197

A front extension arm 179 fixed to 6 extends substantially parallel to this lower arm 178. The front end of the lower arm 178 has a horizontal outer lower axis 182, and the arm 17
9 are provided with outer upper shafts 181, respectively. The two shafts 181 and 182 are connected to each other by a vertical link 183.

Forward and backward movement of arms 178, 179.

Controlled by cam 64. Referring to FIGS. 24-35, a tappet 186 is fixed to the shaft 171. Thus, when the cam 64 rotates, the tappet 186 pivots the shaft 171, and this movement is transmitted to the arm 173 fixed to the shaft 171, moving the arms 178, 179 forward and backward.

Forward and rearward movement of arms 178, 179 is controlled by cam 65. Referring to FIGS. 26-28, the follower 191 is pivoted forward of the timing shaft 61 by a pivot attached to the machine frame. The rear end of the follower 191 is connected to an arm 194 via a link 193, and this arm 194 is fixed to a shaft 177.

Therefore, when the cam 65 rotates, the shaft 177 rotates, and the

The jaws open and close in time with the movement of arms 178, 179. Normally, spring 232 biases jaw members 222, 229 to the closed position and also biases members 219, 226 to the open position. It is biased toward

Because the jaws are closed by a flexible spring 232 rather than an active mechanical action, variations in the thickness of the batch 124 can be accommodated. As the cam 65 rotates, the shaft 176 swings and moves the link 217 forward, moving the bin 233 to the front end of the slot 228 and thus forcing the jaw member 22

51 is formed with six holes 352, and the number and position of the holes 352 are determined depending on the holes to be punched in the paper. The rear end edge of the plate 351 is bent in the horizontal direction by a protruding portion 360 that acts as a stopper to restrict insertion of the batch 124 into the middle. The distance between the stopper 360 and the hole 352 determines the distance from the edge of the paper perforation 201
A vertically crossing guide plate 353, which is an extension of the plate 351, is provided immediately in front of the plate 351, and a gap 355 is formed between the plates 351 and 353 to limit the amount of paper that can be perforated at the same time.

As shown in FIG. 7, punch motor 301 rotates a horizontal shaft 236 carrying a bobbin connected to a pulley on shaft 111 via a series of belts 237. As shown in FIG.

Batch 124,1 positioned within discharge slot 208
25 contacts belt 237 and is moved forward. These batches are collected in tray 238 and seated on bottom 239 until a stack 49 of perforated paper corresponding to first stack 49 is formed.

1- At the start of the abdominal movement, the arms 178, 179 are in the raised and retracted position, and the jaw members 225, 227 are open (see FIG. 5).

The drawer 71 is empty and the advancer is in the fully advanced position. The operator unlocks the latch and the drawer 71
forward and then tilt the drawer so that it extends upward and forward. The stack 49 is inserted into the drawab 1 by direct projection of the advancer 73. The drawer is then closed and locked, and the stack is advanced into the receptor 85.

Stack 49 presses arm 247 and switches 246
is connected, and the motor 56 is energized to rotate the shaft 61.

At this point in machine operation, the cam 63 swings the lever 96 forward, pushing the shaft 74 forward and pressing the stack 49 against the receptor back 86.
03 is connected, the shaft 111 is rotated by the punch motor 301, which causes the right side support 98 to swing, and the extracted paper batch 124 (in other words, the suitable capacity of the punch) is pushed forward and transferred to the receptor 85. It enters inside, is tilted to the right, enters the space between the rear ends 91 of the member 73, and further enters the stabilizer 123.

As shaft 61 continues to rotate, the force of cam 62 acting on advancer 73 relaxes, cam 68 pushes paper retractor bin 133 forward against the force of spring 136, pushes the remainder of the stack forward, and then The finger 149 is lowered in front of the batch 124 against the force of the spring 151.

The stabilizer 123 prevents the batch 124 from falling forward during the above operation.

Arms 178, 179 are moving forward and downward with the jaws open. When the cam 65 reaches the position shown in FIG.
Pull 3,227 backwards. Changes in the thickness of batch 124 can be accommodated by spring 232.

As the cams 64, 66 continue to move, the arms 178, 17
9 lifts the batch 124 upwards and slightly backwards so that the lower end of the first batch 124 is in the punch slot 20
7 (see FIG. 21), and at this point the swing guide 197 is in a position behind it. The batch 124 has descended to the bottom of the punch slot 207, as shown in FIG. At this point, the cam 63 is connected to the punch motor 3.
01 is excited and the first batch 124 is punched with a punch. The scraps are removed from the bent lower end 241 of the member 197.
After that, the scraps fall into the tray, where the scraps are collected and can be removed if necessary (see Figure 22).
.

While drilling of batch 124 continues, the next batch 125 is removed in the same manner as the first batch. Further, the arms 178, 179 first move upward, then forward, and finally downward. Next, as shown in the position shown in FIG. 25, the jaws are closed, the front jaw grips this second notch, and the rear jaw grips the drilled base hole 124.

The arms 178, 179 then move to their fully raised position and move slightly rearward, i.e. from the position of FIG. 29 to a position approximating that of FIG. Once reached, the jaws are opened by the cam 64,
The second batch is released and placed into punch slot 207 and the first batch is released and placed into ejection slot 208 between members 197 and 204. At this time, member 197 is in the forward position.

As the second batch 125 of paper is perforated, the shaft 236 rotates to move the batch 124 being discharged downwardly and forwardly via the belt 237 so that the batch 124 is placed in the tray 238 as shown in FIG. fall inside.

The batch drilling cycle is repeated until the entire stack 49 has been drilled.

A limit switch 246 is provided on the front side of the bag 86 and includes an arm 247 extending forward.

Since the notch 248 is formed in the advancer 73,
Only the paper in the receptor 85 holds the switch arm 247 in neutral force (i.e., backwards). When the arm 247 is free to move itself forward, it senses that there is no paper in the receptor. At this time, the solenoid valve 251 is immediately energized and its plunger 252 is pressed.The link 253 attached to the plunger 252 moves to the lever 158.
Pull the Advance 73 forward to the fully open position. The machine then stops.

To resume operation, open the drawer 71 again,
A new stack 49 is loaded.
