Description

[Detailed description of the invention] The present invention relates to automatic staplers.

Conventionally, this type of automatic stapler is operated by inserting an object to be bound, such as a sheet of paper, into a binding opening of the device. The operation is such that a pushing member that moves up and down forcibly pushes down the staple at the binding opening and drives it into the material to be bound.The stapler is used to adjust the binding position for the set paper. This is done by moving the paper. If the stapler has one binding mechanism and requires binding in two locations, the paper side is moved and the operation is repeated twice. Furthermore, when two binding mechanisms are provided, binding can be performed in two places at once, which is convenient for work.

However, in the case of a stapler that has two binding mechanisms, the binding mechanisms are fixedly arranged, so the binding interval cannot be changed depending on the paper width, and depending on the paper, the binding interval may vary. They were either too narrow or too wide, looked unsightly, and caused various inconveniences.

It is vertically movable within a vertical guide slot 51 formed in the side plate 2 and horizontally suspended. and,
At both ends of this pushing rod 50, left and right pushing mechanisms 52, which are constructed of, for example, a toggle mechanism, are disposed.

The pushing mechanism 52 includes a pair of upper and lower toggle rods 53A,
53B is attached to the shaft, and the upper and lower toggle rods 53 are attached to the shaft.
The upper end of A is pivoted to the side plate 2 at a position above the pushing rod 50. On the other hand, as shown in FIG. 2, a connecting elongated hole 54, which is elongated in the vertical direction like the elongated guide hole 51, is formed in the side plate 2 below the elongated guide hole 51 for raising and lowering the pushing rod 50. A pushing rod connecting plate 55 whose lower part fits into the connecting long hole 54 and moves up and down along the connecting long hole 54 is provided. It is pivoted to the lower end of the toggle rod 53B. A through hole 56 through which the pushing rod 50 passes is formed in the upper part of the pushing rod connecting plate 55, and the pushing rod 50 is connected to the pressing rod 50 so as to be movable in the horizontal direction.

Further, the other end of the action plate 58, one end of which is pivoted to the crank plate 57, is pivoted to the mutually pivoted portions of the pair of toggle rods 53A, 53B. In addition, the crank plate 57

When the pushing rod 50 is further pushed downward, the staple pressing plate 47 lowers to drive the staple A into the paper, and the staple bending guide plate 40 bends the staple A to bind the paper (the second (See Figure 8). This is due to the operation of the crank plate 57 and the action plate 58, which rotate as the motor 60 is driven, and when further driven, the pushing mechanism 52 is extended. When the pushing mechanism 52 is extended, the pushing lever 50 is returned upward, so that the stapler main body 45 that had been holding the sheet and the staple pressing plate 47 that had been driving the staple A are moved from the staple Winding spring 3
It returns to the original position with the restoring action of step 8. When returning to the upper position, the locking part 42 of the pushing rod action frame 25 locks with the lifting locking part 43 of the stapler holding frame 35 to stop it at the fixed position (see FIG. 9), and the drive of the motor 60 is also stopped. Prepare for the next action. The motor 60 is driven by the binding switch 108 as shown in FIG.

The engaging protrusion 61 protruding from the motor switch 11
By turning 0 off, the motor circuit is opened.

Next, the stapler moving device 70 will be explained. As shown in FIGS. 2 and 12, the stapler moving device 70 includes a horizontal guide means 71 that allows the stapler actuating device 20 to move laterally, and an annular winding hook stretched laterally within the machine frame 1. It is constructed by disposing a conduction node 72, a rotating means 73 for rotating the wrapped conduction node 72, and a display means 74 indicating the amount of movement of the wrapped conduction node 72.

As mentioned above, the pushing rod 50 passes through the stapler actuating device 20.
0 is movable in the length direction of this push rod 50. That is, in order to ensure smooth lateral movement of the stapler actuating device 20, the front surface of the stapler actuating body frame 21 below the needle bending guide plate 40 is provided with the markings shown in FIG.
As shown in FIG. 1, a pair of moving wheels 75 are arranged side by side in the lateral direction. Further, a moving rail 76 having an L-shaped cross section is provided at the front lower part of the machine frame 1, and the moving wheels 75 fit into the grooves of this moving rail 76 and roll. That is, the horizontal guide means 71 is made up of the pushing rod 50, the moving rail 76, and the wheels 75.
shall be.

Above the stapler operating device 20, an annular winding transmission node 72 made of a chain is stretched in the transverse direction within the machine frame 1 by a tension wheel 77 made of a chain sprocket. This annular wrapped conduction node 72
A coil spring 78 is disposed inside to keep the winding conduction node 72 in tension at all times to prevent it from loosening.
A mounting plate 79 is disposed horizontally on the machine frame 1, and the tension wheel 77 is pivotally supported by the mounting plate 79. A rotary dial 80 is fixed to the shaft of one tension wheel 77, and the machine frame 1
The winding conduction node 72 is rotated from the outside via this rotation dial 80 (see FIGS. 1 and 5). That is, this rotation dial 80 is used as the rotation means 73 of the winding conduction node 72.

In addition, for example, the upper winding conduction node 72 in one direction between the tension wheels 77 and the lower winding conduction node 72 in the other direction.
The pair of stapler actuating devices 2 are arranged at a line symmetrical position with respect to the center of the winding conductive node 72 in the tensioning direction.
0 are respectively fixed via the winding conduction node fixing plate 83. Therefore, when the rotary dial 80 is rotated, the winding conduction node 72 rotates, and at this time, the upper and lower portions of the winding conduction node 72 move in opposite directions (see FIG. 12).

Further, the winding conduction node 72 is provided with a display means 74 that indicates the amount of movement of the winding conduction node 72. The display means 74 includes an indicator body 81 with an acute-angled tip fixed to the winding conduction node 72, for example, one winding conduction node fixing plate 83, and an indicator body 81 located outside the machine frame 1 near the movement path of the indicator body 81. The scale plate 82 is arranged so as to be visible from the outside. Note that the scale of the scale plate 82 is 1/2 because the relationship between the amount of movement of the index body 81 and the distance between the two stapler operating bodies 20 is 1:2.
Displayed on a scale of . Therefore, when the winding conduction node 72 is rotated by the rotation means 73 and 80,
The indicator main body 81 fixed to the winding conduction node 72 moves along the scale plate 82, and the indicator main body 8
By reading the movement value of 1, the winding conduction node 7
2. Furthermore, the amount of movement of the stapler actuating device 20 can be known (see FIGS. 1 and 12).

At this time, the stapler actuating body frame 21 of the stapler actuating device 20 is supported and arranged in an upright manner within the machine frame 1, and in the upper part, the horizontal direction which penetrates the elongated hole 30 of the pushing rod working frame 25 is disposed. At the push rod 50,
In the lower part, moving wheels 75 within the moving rail 6
They are each supported by horizontal guide means 71 consisting of. Therefore, by operating the stapler moving device 70, the stapler actuating device 20 itself can be freely moved laterally along the pushing rod 50 by means of the horizontal guide means 71.

Next, the control mechanism 100 for moving the push rod 50 up and down once will be explained. As described above, the pushing rod 50 is connected to the motor 60 via the pushing mechanism 52, and the pushing rod 50 is connected to the crank plate 5 in order to move up and down once.
7 rotates once. The control mechanism 100 is constructed as shown in FIG. A fuse 102 and a door switch 111 (described later) follow the plug 101, and the AC power is further guided to a rectifier circuit 104.

A paper detection switch 106 for charging the capacitor 105 is connected to the positive output terminal of the rectifier circuit 104.
The normally closed contact 106B of the paper detection switch 106 is connected to the common contact 106C of the paper detection switch 106, which is in contact with the rectifier circuit 1 through the capacitor 105.
Connected to the negative side of 04. Further, between the normally open contact 106A of the paper detection switch 106 and the negative side of the rectifier circuit 104, an automatic manual switching switch 107 using a tumbler switch and a manual binding switch using a push button switch are connected. A solenoid of a relay 109 is connected through a parallel connection of 108. By keeping the automatic manual changeover switch 107 on the ON side, when the insertion of paper is detected, it will automatically operate to perform the binding operation on the paper, and by leaving it on the OFF side and turning on the binding switch 108. It is designed to perform binding operations on paper.

Furthermore, a motor 60 is connected to the input end of the rectifier circuit 104 via a contact 109A of the relay 109 and a motor switch 110 which is connected in parallel to the cam plate.

In the figure, 111 is a door switch 111 that is closed by coming into contact with the front door 10, which is swingably disposed on the front of the machine frame 1 so that it can be opened and closed.
11, the entire circuit is opened when the door is opened as a safety measure to prevent the stapler body 45 from operating.

Therefore, normally the capacitor 1 is connected via the normally closed contact 106B of the paper detection switch 106.
05 is being charged, and then when paper detection switch 106 is turned on when paper is inserted, capacitor 10 is charged.
The solenoid of the relay 109 is energized by the electric charge stored in the stitching switch 109 when the stitching switch 109 is in the automatic mode, and is energized by pressing the stitching switch 108 when the stitching switch 108 is pressed in the manual mode. Therefore, by energizing the relay 109, its a contact 10
The motor 60 rotates via 9A. Then, due to the rotation of the cam plate 62 accompanying the rotation of the motor 60, the motor switch 110 is disengaged from the engagement protrusion 61 and closed, and the rotation relay 109 of the motor 60 is closed.
Even after the excitation by the capacitor 105 to
Continue rotating while rotating. Then, when the end of one rotation approaches, the motor switch 110 is activated by the cam plate 62.
Since the motor switch 110 is opened by engaging with the engaging protrusion 61 of the motor 60, the motor 60 stops after one revolution.

Therefore, when paper is inserted into the paper insertion slot 6 and the paper detection switch 106 is turned on, the paper is bound.

In the figure, 112 is a reversing switch connected between the motor switch 110 and the relay A contact 109A and the motor 60, which prevents the stapler actuating device 20 from being erroneously activated when the paper or the like is larger than a predetermined stitching thickness. This is used to release the stapler actuating device 20 from the locked state.

Further, as shown in FIG. 2, the paper detection switch 106 is attached to the paper insertion guide plate 5 via a mounting plate 113 at a substantially central position of the machine frame 1.
This mounting plate 113 can be fixed at an appropriate position in the longitudinal direction of the machine frame 1. By appropriately changing the mounting position of the mounting plate 113, the distance from the front edge of the paper to the binding position can be freely changed.

Since the present invention is configured as shown above, the push rod 5
Even with a simple input form of zero vertical movement, the stapler main body B can be operated to appropriately and reliably perform stapling in accordance with the paper thickness.

That is, a push rod working frame 25 is provided in the stapler operating body frame 21 so as to be movable up and down, and has a vertically long elongated hole 30 in which the push rod 50 that moves up and down in the machine frame 1 engages. A push rod 50 is located inside the moving rod working frame 25.
A pushing rod abutting plate 31 is arranged to be movable up and down within the elongated hole 30 so as to come into contact with the upper surface, and a spring body is disposed between the lower surface of the pushing rod abutting plate 31 and the pushing rod working frame 25. 3
2 is compressed, and a pressing plate holding portion 34 is provided on the lower surface of the pushing rod action frame 25 to hold the upper part of the staple pressing plate 7 of the stapler main body 45. Holding frame 35
is disposed in the stapler operating body frame 21 so as to be vertically movable, so that the downward movement of the pushing rod 50 pushes the pushing rod operating frame 25 downward via the pushing rod contact plate 31 and the spring body 32. By the downward pushing of the pushing rod action frame 25, the stapler main body 45 having the staple pressing plate 47 connected via the holding part 34 descends downward, and the stapler main body 45 and the needle bending guide plate 4
Holds paper such as documents to be bound with 0 and 0. When the pushing rod 50 is further pushed downward, the needle pressing plate 60 is lowered to drive the staple A into the paper, and the staple A is bent by the needle bending guide plate 20, so that the paper can be bound. .

In addition, when bending the staple A to fix the binding, the spring body 32 is applied and the accumulated elastic restoring force is used to transmit the downward pushing motion of the push rod 50 to the staple pressing plate 47, so that the binding can be fixed. When the thickness is small, the resistance of the binding needle A to penetrate the paper is small, so the elastic restoring force applied and accumulated in the spring body 32 is small, and when the thickness of the binding is large, the binding Since the resistance of the needle A to penetrate the paper is large, the elastic restoring force accumulated in the spring body 32 is large. For this reason, when the binding thickness of the paper is large, while the resistance of the downward pushing of the staple pressing plate 47 becomes large, the downward pushing of the pushing rod 50 by the driving force of the motor 60 is difficult. By being loaded, elastic restoring force is accumulated in the spring body 32. As the pushing rod 50 is returned upward, the applied accumulated force becomes maximum just before it is released, and the pushing rod 50 is pushed downward, and the release is caused by the binding needle pressing plate. 47 as a force to drive the staple A into the paper, it is extremely effective for thick paper, and is therefore not affected much by the binding thickness of the paper, etc. Optimal binding operation can be performed. Moreover, the spring body 32
, the binding resistance to the paper is not directly transmitted to the motor 60 as a reaction force, and the motor 6
0 drive safety can also be achieved.

A stapler main body 45 is provided on the lower surface of the pushing rod working frame 25.
A press-down plate holding part 34 is provided to hold the upper part of the staple press-down plate 47, and a locking part 42 provided on the push-rod action frame 25 is engaged with the stapler holding frame 35 when the push-rod action frame 25 is raised. Since the rising locking portion 43 is provided, the stapler main body 45 can be returned to perform the stapling operation by one vertical movement of the push lever 50, and when returning, the rising locking portion 43 is provided. The stop portion 42 is engaged with the lifting stop portion 43 to stop at a fixed position and enter a standby state.

In addition, a push rod 50 that moves up and down within the machine frame 1 along a vertically long guide hole 51 opened in the side plate 2 of the machine frame 1 is disposed in the horizontal direction of the machine frame 1. The working frame 25 is provided with a vertically long elongated hole 30 through which the pushing rod 50 passes, and a pushing rod contact plate 31 is provided in the pushing rod working frame 25 so as to come into contact with the upper surface of the pushing rod 50.
Since the stapler actuating device 20 is disposed within the machine frame 1 by arranging the stapler operating device 20 so as to be movable up and down within the elongated hole 30, the pushing rod 50 can be freely moved in the penetrating direction within the elongated hole 30. , the stapler actuating device 20 can be moved laterally, and in configuring the automatic stapler of the present invention, the stapling position of the staple A can be easily changed. In addition, since the input form can be simple, such as the vertical movement of the push lever 50, the overall configuration can be simplified.

The stapler actuating devices 20 are disposed so as to be movable in the lateral direction via a horizontal guide means 71, and an annular winding conductive node 72 is horizontally stretched over the stapler actuating devices 20 by a tension wheel 77. 77
The pair of stapler holding frames 35 are respectively attached to the winding conduction nodes 72 in one direction and the winding conduction nodes 72 in the other direction in a line-symmetrical position with respect to the center in the tensioning direction of the winding conduction nodes 72. Since the rotation means 73 for rotating the winding conduction joint 72 is provided on the winding conduction joint 72, when binding the sheets with the two stapler bodies 45, this binding position can be changed. An automatic stapler that can be easily modified can now be provided.

That is, since the rotation operation of the rotation means 73 rotates the winding conduction node 72 which is stretched in an annular shape in the lateral direction, the left and right portions fixed in one direction and the other direction of the winding conduction node 72 are rotated. The stapler actuating device 20 moves in opposite directions to the left and right via the horizontal guide means 71 and the pushing rod 50. The mutual movement in the opposite direction causes the stapler actuating devices 20 to approach or move away from each other, and the mutual distance can be freely adjusted and corresponds to the binding distance of the sheets. Further, the stapler main body 45 of the binding mechanism is held in the stapler operating body frame 21 so as to be freely operable by a pushing rod 50 that moves up and down.
To securely bind sheets of paper no matter where 0 is moved and set.

Furthermore, since the winding conduction node 72 is provided with a display means 47 that indicates the amount of movement of the winding conduction node 72, the binding positions by the two stapler bodies 45 can be confirmed.

In addition, by using a chain in the annular winding conduction node 72, movement becomes reliable and accurate movement is possible.

As explained above, according to the present invention, not only can binding be performed reliably with a simple configuration, but also the optimal binding operation can always be performed regardless of the thickness of the documents to be bound. This provides various excellent effects such as being able to freely and easily set the interval between the staples and also being able to confirm the interval between the staples.
