Abstract

PURPOSE:To prevent breakage of a sheet material by so controlling as to move an elastic sewing member to a position easy to remove said sheet material after said sheet material is sewed. CONSTITUTION:When a punching or boring position of a sheet material 2 deter mined by the size of a ring is sent approximately to the center of an end of the ring, an upper support member 52 and a lower support member 56 are moved in the same direction so as not to change the opening degree of the resin ring 6 until an end of the ring 6 passes through the boring portion of the sheet material 2. After the end of the resin ring 6 penetrates the boring portion, the upper and lower support members 52 and 56 are moved in a direc tion to be closed. After the resin ring 6 is closed and the sheet material 2 is completely sewed, the upper support member 52 is so controlled as to be moved in a direction shown by an arrow, and the resin ring 6 supported by the upper support member 52 is moved above a carrier deck 50. Since an elastic sewing member is moved to a position not to hook a transfer line after the sewing work, the sheet material can be easily taken out without being broken or the like.

The lowered position of the presser plate 26 is locked by a lock plate 29, and the release plate 31 unlocks the lock plate 29.

Further, as shown in FIG. 11, sensor levers 32a and 32b are provided which rotate integrally with the handle 16. When the handle 16 is in the upper position, an upper limit sensor 35 faces the sensor lever 32a, and an upper limit sensor 35 is located in the lower position. Lower limit sensors 36 are provided which face each other at a certain time.

Next, the conveying means 5 will be explained with reference to FIGS. 1, 7, and 11.

Conveyance roller 4 slightly protruding from the hole of sheet material t1100 9

The pickup lever 41 is pivotally supported at its intermediate portion by a pin 41a fixed to the device 1, and the lower end portion of the pickup arm 42 is pivotally supported to the lever 41 by a pin 44b on the left side of the pin 41a.

A right end portion of a lever 44 is pivotally attached to a pin 41a that pivotally supports the pickup lever 41.
An upper conveyance roller 40b is pivotally supported at the left end of the conveyance roller 40b.

The pin 41a has a gear 54a integrated with the pulley 48a.
is pivotally supported, and a gear 54a integrated with a pulley 54b meshes with the gear 48a. Lower conveyance roller 40a
The plurality of pulleys 12 integrated with the above-mentioned pulley 4b are connected by a belt 8b, and the above-mentioned pulley 4b and the pulley attached to the output shaft of the conveyance motor 37 are connected by the belt 8b.

rotates clockwise, and the upper conveyance roller 40b rotates counterclockwise. In this state, when the upper conveyance roller 40b is lowered and the sheet material 2 is sandwiched between the upper and lower conveyance rollers 40a and 40b, the sheet material 2 is conveyed to the right in the figure.

Further, one end of a tension spring 41d is attached to the lever 41, and is biased clockwise around the pin 41a, and the rotational behavior of the pickup lever 41 causes the arm 42 to move upward via the pin 41b. energized. Further, a projection 41c is provided at one end of the vertical portion of the lever 41, and this projection 41c is provided at one end of a lock arm 46 and engages with a hook 46a. 45 supports the side root of the device 1, and the other end is the operating rod 4 of the solenoid 47.
When the solenoid 47 is turned on, the lock arm 46 rotates clockwise and its hook 46a is engaged with the protrusion 41c, and when the solenoid 47 is turned off, the lock arm 46 rotates counterclockwise. It is designed so that it can be rotated and removed from the protrusion 41C.

In addition, by operating the handle 16, the sensor lever 36b
rotates counterclockwise to block the lower limit sensor 39 and at the same time lower the arm 42 against the upward biasing force, the left side of the pickup lever 41 lowers and engages the engagement provided on the lever 41. The lever 44 is released from the stopper 41e, and the lower conveyance roller 40b presses the lower conveyance roller 40Δ together with the lever 44 due to its own weight.

In FIG. 7, on the upstream side of the perforation means 3 there is a regulating member (
A sheet material regulating means) 49 is disposed, and the upper portion of the sheet material regulating means 49 is pivotally supported by a pin 49a.
In the figure, it is freely rotatable in the clockwise direction and is suspended counterclockwise while being prevented from rotating by a regulating stopper 49b.

Reference numeral 51 denotes a ring entrance guide for preventing the dispersion of the leading end of the bundle of sheet materials 2 being conveyed, and is rotatably suspended clockwise from a pin 51a fixed to a stationary member (not shown).

Next, the ring opening/closing means R will be explained with reference to FIG. 1 and FIGS. 4 to 6. An upper claw (upper support member) 52 that extends horizontally in a comb shape and has a tip curved diagonally upward is guided vertically inside the side wall of the ring opening/closing part main body 7a, and is guided through a gear train 53. It is designed to be driven by a motor 55. In addition, a large number of lower claws protrude obliquely upward and are arranged so that their tips are perpendicular to the conveying direction of the sheet material 2 (
A lower support member) 56 is driven by a motor 59 via a gear train 57. Further, a ring 6, which is a machine mounting member made of plastic and having a large number of horizontally curved substantially circular claws on one spine, is attached to the upper support member 5.
2, the sensor lever 60, which detects the dimensions of the resin ring 6 by rotating counterclockwise by a distance corresponding to the outer diameter of the ring 6, is rotated clockwise by its shaft 60a. It is pivoted and biased to move. A plurality of ring sensors 61a and 61b are arranged below the sensor lever 60 to detect the presence or absence of the link 6 on the upper support member 52 and also to detect the ring size.

Next, the operation will be explained mainly according to the flowchart of FIG. First, the resin song 6 (hereinafter referred to as a resin ring) is set on the two-part support member 52 shown in FIGS. 4 and 5. In the initial state, the ring sensor lever 60 is
Although it is pressed against the upper support member 52 by an elastic member (not shown), by setting the resin link 6 on the upper support member 52, it rotates counterclockwise in FIGS. 4 and 5, and the lower end of the link The presence or absence of the resin ring 6 is detected by blocking the sensors 61a and 61b. Ring sensor 61a
, 61b is composed of a plurality of sensors, and each sensor is turned on/off.
○The size of the resin ring 6 is recognized by the combination of FF.

The size of the resin ring 6 is determined by the size of the sheet material 2 desired for mounting on the machine.
Since several types are available depending on the thickness of the hole, the numerical value to be set in the next process is determined by detecting the link size, thereby achieving automation after drilling.

Insert the sheet material 2 from the operation side (left side in FIG. 1). At this time, as shown in FIG. 7, the perforation position of the sheet material 2 is defined by abutting the sheet material 2 against the stopper 13a. Further, in order to prevent the tip end of the sheet material 2 from lifting upward, a sheet material regulating means (human logite) 49 is provided on the upstream side of the perforating means 3. This sheet material regulating means 49 functions to press down the sheet material 2 and at the same time, by keeping the gap between it and the die 10 constant, it regulates the insertion thickness of the sheet material 2 to the extent that it does not exceed the perforation capacity. . Moreover, by placing the sheet material 2 on the mounting table 9, the sensor lever 11 rotates and the sheet sensor 13
The presence or absence of the sheet material 2 is detected by interrupting the flow.

It is necessary for the operator to punch holes at appropriate positions in the sheet material 2 depending on the size of the resin ring 6 to be used. That is, by setting the resin ring 6 on the upper support member 52 of the machine stand, the ring sensor lever 60 is activated.
The size of the resin ring 6 is recognized by ring sensors 61a and 61b. Then, in order to define an appropriate perforation position in the sheet material 2, the stoppers 13a and 13b are interlocked.

In this embodiment, there are two types of perforation positions, one of the solenoids 15a and 15b is selected based on the signal after the six resin rings are set, and one of the unnecessary solenoids 15a and 15b is pulled down to form the sheet material 2. I'm trying to hit the nail on the head. Incidentally, it goes without saying that a plurality of the soba noodles 13a and 13b may be provided, and may also be configured to be movable.

Next, the punching process will be explained. As shown in FIGS. 9 and 10, the bunch 20 is supported by guides 22 and 23 that form a pair with the die 10, and the fact that each of the guides 22 and 23 is composed of three pieces is a manufacturing problem. , and each may be composed of one sheet. This vertically independent configuration allows the resin ring 6 to be pulled out toward the entrance side while being mounted on the sheet material 2 after the work is completed.

In order to perforate the sheet material 2 that has abutted against the stoppers 13a and 13b, the handle 16 is first pushed downward. The position of the handle 16 is detected by sensor levers 32a and 32b, an upper limit sensor 35'', and a lower limit sensor 36, which rotate together with the handle 16. handle 16
By pushing down, the punch 20 is lowered and raised by the cam mechanism configured together with the shaft 17 to strike the sheet material 2.
drilling is performed.

In this embodiment, the upper conveying roller 40b and the lower conveying roller 40
a are arranged at intervals, and a pickup configuration is adopted as shown in FIG. 11. This is because when inserting the sheet material 2 and hitting it against the stoppers 13a and 13b,
The upper conveyance roller 40b is in a retracted position from the conveyance path, and is lowered to the conveyance path in order to convey the sheet material 2 to the binding section after the punching operation is completed.

In this mechanism, first, by pushing down the handle 16, the lower limit sensor lever 32b rotates, and the lower limit sensor 36
At the same time, the pickup arm 42 is pushed down.

As a result, the pickup lever 41, which is configured to be rotatable together with the pickup arm 42, is pushed down.
The upper transport roller 40b lowers its own weight 'C, and together with the lower transport roller 40a, presses down the sheet material 2 to enable stable transport. At this time, a pin 41 is fixed to the pickup lever 41 so that the pickup lever 41 does not return.
c is gripped by a claw 46a at the tip of the lock arm 46.

After punching the sheet material 2, the handle 16 is pulled up and the punch 20 is pulled out from the sheet material 2. At this time, the sheet material 2 is lifted due to the friction between the punch 20 and the sheet material 2, and hits the guide 23. If the sheet material 2 is pulled diagonally and then pulled out, the stopper 13
Since the sheet deviates from the position determined by a and 13b, it is held down by the sheet holding mechanism shown in FIGS. 12 and 13.

In the initial state, this mechanism is pressed against the guide 23 by the spring 27, but it descends as the handle is operated, and presses the sheet material 2 to prevent the sheet material 2 from shifting during drilling. In order to help the punch 20 come off, the punch 20 is prevented from returning by the lock plate 29, and the punch 20
The cam mechanism of the release plate 31 returns to the initial state at the time when all the parts have come out of the sheet material 2.

Next, when the upper limit sensor 35 detects the completion of drilling, the solenoids 15a and 15b actuate the stopper 13a.
, 13b is lowered,
By the conveyor motor 37, through the belt and gear drive,
The lower conveyance roller 40a and the upper conveyance roller 40b are simultaneously driven to convey the sheet material 2. The above conveyance roller 40a
, 4ob, it is possible to convey the sheet material 2 using either the vertical drive method, but the vertical drive is effective in increasing the conveyance accuracy in the case of a large number of sheets.

The transported sheet material 2 is sent to the ring opening/closing section via the transport table 50. At this time, in order to prevent the tip of the sheet material 2 from curling and disordering and to ensure the binding of the sheet material 2 to the resin ring 6, a ring entrance regulating plate 51 is provided on the conveyance path to prevent a gap. It is regulated.

The perforation and conveyance of the sheet material 2 have been explained above, and now the ring opening/closing section will be explained.

The outline of the ring opening/closing part is as shown in the right half of Figure 1.
Sensors 61a, 61b that detect the sizes of the upper support member 52, the lower support member 56, gear trains 53, 57, motors 55, 59, and resin link 6 for driving each of them.
It consists of departments, etc.

As mentioned above, by sandwiching the resin ring 6 between the upper support member 52 and the link sensor lever 60,
The size of the resin ring 6 to be used is recognized and the opening amount of the resin link 6 is determined. At this time, the resin ring 6 used
The opening amount varies depending on the upper support member 52.
The resin ring 6 is opened by the lower support member 56 and the lower support member 56, but the amount of movement of both members is also different.

The opening operation of the resin ring 6 will be explained with reference to FIGS. 5 and 6. The set resin ring 6 is attached to the upper support member 5
2, and is sandwiched between the ring sensor lever 60 and the ring sensor lever 60. A key-shaped lower support member 56 is moved in parallel to the inside of the resin ring 6 by a cam mechanism (not shown) as shown in FIG. Thereafter, the upper support member 52 and the lower support member 56 are each moved to a specified opening amount to open the opening.

In this embodiment, the upper limit sensor 35 of the handle 16 is configured to perform the opening operation at the same time as the punching operation ends, but the timing of this opening is until the sheet material 2 being conveyed reaches a specified position. You can do whatever you want between them. This open state is as shown in FIG. 6, but the resin ring 6 is an elastic member, and the opening amount 72 and the ring tip position 73 should be adjusted as far as the elastic limit is not exceeded. This configuration is such that the position at which many sheet materials 2 can be stitched is empirically set by collecting various data, and the optimum setting is made without hesitation each time the operator sets the resin ring 6.

Since the conveyed sheet material 2 is perforated at a position determined by the ring size, the sheet material 2 is fed until the perforated position is approximately at the center of the link tip position 73. When the conveyance operation is completed, the upper support member 52 and the lower support member 56 move in the same direction so that the opening amount of the resin link 6 does not change, until the tip of the resin ring 6 passes through the perforation of the sheet material 2. After moving and penetrating, the upper support member 52 and the lower support member 56 are moved in a direction to close them.

After completing the binding of the sheet materials 2, the resin link (elastic binding member) 6 is closed in the state shown in FIG. 17(a). At this time, most of the resin ring 6 is located below the conveyance table 50 and is supported only by the upper support member 52.

In this state, when the operator pulls out the sheet material 2 together with the stitched resin links 6, the resin ring 6 gets caught on the conveyor table 50, resulting in the resistance exerted by the sheet material 2.

Therefore, in the present invention, after the resin ring 6 is closed and the sheet materials 2 are stitched together, the upper support member 52 is moved as shown in FIG.
The resin ring 6 is controlled to move in the direction of the arrow in a), and as a result of this movement, the resin ring 6 supported by the upper support member 52 is moved inside the conveyor table 50 (transfer table 50) as shown in FIG. 17(b). moved to a higher position). By this movement of the resin link 6, when the sheet material 2 is taken out by an operator, the vI4 resin link 6 is prevented from being caught on the conveyance table (conveyance path) 50, and the sheet material 2
can be easily taken out without causing damage.

Then, when the bound sheet material 2 is pulled out toward the front side, the regulating member 71 and the ring entrance regulating plate 51 are
It is configured to be able to move freely in the drawing direction of the sheet material 2, and does not interfere with the drawing operation of the sheet material 2.

The operations of each of the above steps are displayed on the operation panel to provide support to the operator in sequence and to enable visual confirmation up to the final step, and a block diagram of the control system is shown in FIG.

Next, the operation in manual mode is shown in Figures 1, 15, and 16.
This will be explained using figures.

Normally, the sheet material machine stand in automatic mode can operate when the number of sheets is less than the perforation capacity or when the sheet material 2 has an appropriate thickness. However, when binding the number of sheets that exceeds the perforation capacity, do not use the automatic mode, but divide the sheet material 2 into the number of sheets below the perforation capacity several times, perform the perforation work, and then use the resin link 6. It will be stitched together. Furthermore, when it is desired to add or replace sheet materials 2 to the roughly bound sheet materials 2, the manual mode is used instead of the automatic mode.

To perform stitching in manual mode, first rotate the stitching means R shown in FIG. 1 clockwise about the fulcrum 75,
It is held at the position shown in FIG. 5 by a fixing means (not shown). At this time, when the automatic/manual changeover switch 76 attached to the stitching means R is rotated, it is turned OFF and the manual mode is detected. Then, the auxiliary guide cover 7 is attached to the appropriate position of the sheet material machine mounting device 1.
9 also rotates counterclockwise around the shaft 82, "C1 1st
The position will be as shown in Figure 5. This auxiliary guide cover 79 is
In the automatic mode, the stitching means R is held at the position shown in FIG. 1 by interlocking with a cover (not shown), and in the manual mode, the
Move to the position shown in the diagram.

Next, the actual stitching work will be explained.

First, the resin links 6 used for stitching are attached to the upper support member 5.
2 and the lower support member 56. The sheet material 2 to be bound is divided into several parts whose perforation capacity is below, and the perforation work is performed in the manner described above. Then, the perforated portion is inserted into the claw portion 6a of the open resin ring 6 as needed, and after inserting the necessary sheet material 2, the resin ring 6 is closed and the sheet material 2 is pulled out to complete the stitching work. . When inserting the sheet material 2 into the resin ring 6, the auxiliary guide cover 79 serves as a guide and a mounting base for the sheet material 2, as shown in FIG. Can do the work easily.

Since the link sensors 61a and 61b are attached to the sheet material automatic machine mounting system [B, they can only be used when the binding means R is rotated to enter the manual mode.

Since several types of resin rings 6 are actually used depending on the size of the diameter, the opening amount is determined by the operator.

Furthermore, when adding or replacing the sheet material 2, as shown in FIG. The opening/closing operation of the ring 6 and the punching operation of the sheet material 2 are performed to add and replace the sheet material 2.

(g) As described in detail, according to the present invention, the stitching means performs the stitching operation of the sheet materials, and after the stitching operation is completed, the elastic sheet alignment member (for example, an elastic Since the resin ring (resin ring) is moved to a position where it is not caught in the conveyance path (conveyance means), the sheet material can be easily taken out without causing damage to the sheet material.
