Abstract

PURPOSE:To prevent generation of an inadequate punching by providing a regulating means at the upstream side of a punching means to regulate the thickness of a sheet material inserted into said punchig means. CONSTITUTION:In sewing a sheet material 2, the sheet material 2 is inserted in a direction A. At this time, a sheet material requlating means 49 is stopped since it butts against a regulating stopper 49b by its own weight, with maintining a gap (x) constant between the regulating means 49 and a die 10. This gap (x) is determined by the punching efficiency. When the inserted sheet material 2 is completely punched and sewed, it is pulled out in a direction B. At this time, although the thickness of the sheet material 2 is increased since a resin ring 6 used in sewing is attached to an end of the sheet material 2, the regulating means 49 is to constituted as not to be retractable in a clock wise direction, so that the sheet material 2 is able to be pulled out.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a sheet material stitching device, and more particularly, to a sheet material stitching device that performs a stitching operation of sheet materials using an elastic material stitching member. Regarding a matching device.

(B) Conventional technology Conventionally, in a binding device that performs binding using a general elastic binding member provided with a large number of curved claws extending laterally on one spine, perforations are used. A device has been proposed in which the stitching operations of the stitching members are performed manually or automatically in independent operations.

(C) Problems to be Solved by the Invention However, sheet punching machines and binding devices that use elastic binding members (hereinafter also referred to as resin rings) to stitch sheet materials cannot perforate sheet materials at - times. Since the number of sheets is limited, if an attempt is made to insert more sheets into the perforating means and perforate them, a perforation failure may occur and the stitching operation may not be possible.

Furthermore, in order to prevent poor drilling, the operator must measure the number or thickness of the sheets in advance, which has the disadvantage of reducing the efficiency of the drilling work.

In view of this, the present invention provides a sheet material binding method in which a means for regulating the thickness of the sheet material is provided upstream of the perforation means to prevent a sheet material having a thickness greater than that which can be perforated from being inserted into the perforation means. The purpose is to provide a device.

(d) Means for Solving the Problems The present invention has been made in view of the above-mentioned circumstances, and for example, as shown with reference to FIGS. 1 and 7, the perforating means for perforating the sheet material (2) ( 3) and perforated sheet material (2)
A conveying means (5, 40a, 40b) that transports the sheets to a position where they are bound to the elastic binding member (6), and a binding operation for the transported sheet materials (2) by the elastic binding member (6). In the sheet material automatic machine mounting device constituted by a stitching means (R) that performs the following: It is characterized by being provided upstream of the perforation means (3).

(E) Effect Based on the above configuration, when the operator inserts the sheet material (2) into the perforation means (3), the excess sheet material (2) beyond the perforation capacity of the perforation means (3) is removed by the sheet material regulation means ( 49) prevents insertion into the perforation means (3) and the remaining sheet material (2) of perforable thickness is inserted into the perforation means (3). This makes it possible to stably perforate and stitch the sheet material (2) without having to measure the number or thickness of the sheet material 2 by the operator.

Note that the above-mentioned symbols in parentheses are shown for reference to the drawings, and do not limit the configuration of the present invention in any way.

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 bin 41a, and the rotational behavior of the pickup lever 41 causes the arm 42 to move upward via the bin 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 so that a hook 46a engages with the lock arm 46. 45 supports the side plate of the device 1, and the other end is connected to the operating rod 4 of the solenoid 47.
It is pivotally supported at the tip of 7a. When the solenoid 47 is turned on, the lock arm 46 rotates clockwise and its hook 46a engages with the protrusion 41c, causing the solenoid 47 to rotate clockwise.
When the lock arm 46 is turned off, the lock arm 46 rotates counterclockwise and comes off the protrusion 41C.

In addition, by operating the handle 16, the sensor lever 38b
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 41θ, and the lower conveyance roller 40b presses the lower conveyance roller 40a by its own weight together with the lever 44.

In FIG. 7, on the upstream side of the perforation means 3 there is a regulating member (
A sheet material regulating means) 49 is arranged, and the upper part of the sheet material regulating means 49 is pivotally supported by a bin 49a,
In the figure, it is freely rotatable in the clockwise direction, and is suspended counterclockwise with its rotation being prevented by a restriction flange 49b.

Reference numeral 51 denotes a ring entrance guide for preventing scattering of the leading end of the bundle of sheet materials 2 being conveyed, and is rotatably suspended clockwise from a bin 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 binding member made of plastic and has a large number of horizontally curved claws in a substantially circular shape on one spine, is attached to the upper support member 5.
When the claw is inserted into the ring 6, the distance lul! corresponds to the outer diameter of the ring 6. Rotate counterclockwise until the resin ring 6
A sensor lever 60 for detecting the dimensions of is pivoted and urged to rotate clockwise by its shaft 60a. An upper support member 5 is provided below the sensor lever 60.
A plurality of ring sensors 61a and 61b are arranged in a row to detect the presence or absence of the ring 6 on the ring 2 and also to detect the ring size.

Next, the operation will be explained based mainly on the flowchart of FIG. First, the resin ring 6 (hereinafter referred to as resin ring) is set on the upper support member 52 shown in FIGS. 4 and 5. In the initial state, the ring sensor lever 60 is pressed against the upper support member 52 by an elastic member (not shown), but by setting the resin ring 6 on the upper support member 52, it rotates counterclockwise in FIGS. 4 and 5. The lower end blocks the ring sensors 61a and 61b,
The presence or absence of the resin ring 6 is detected. ring sensor 61a,
61b is composed of a plurality of pieces, and each sensor's ON10
The size of the resin ring 6 is recognized by the combination of F and F.

The size of the resin ring 6 is determined by the size of the sheet materials 2 that you wish to stitch together.
Since several types are available depending on the thickness of the ring, the numerical value to be set in the next process is determined by the ring size detection described above, and automation after drilling is attempted.

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. In addition, sheet material 2 that can be perforated or more
A sheet material regulating means (entrance guide) 49 is provided upstream of the perforating means 3 to prevent the sheet material from being inserted into the perforating means 3.

When stitching the sheet materials 2, the sheet materials 2 are inserted in the direction of the arrow shown in FIG. 3(a).

At this time, the sheet material regulating means 49 hits the regulating stopper 49b due to its own weight and is stopped, keeping the gap X between the sheet material regulating means 49 and the die 10 constant. This gap X is defined by the perforation capacity, and sheet material 2 having a thickness greater than this gap X is not inserted by the sheet material regulating means 49, thereby preventing poor perforation or poor stitching.

After insertion, the sheet material 2 that has undergone the perforation and stitching operations is pulled out in the direction of arrow B in FIG. 7(b). At this time, the resin ring 6 used for stitching is attached to the tip of the sheet material 2, and the thickness of the sheet material 2 is increased, but the sheet material regulating means 49 is As shown in , since the sheet material 2 is configured to be retractable in a clockwise direction, the sheet material 2 can be pulled out without any hindrance to the pulling out operation, and the work is completed.

As described above, the thickness of the sheet material 2 is controlled by the sheet material regulating means 4.
9, stable stitching work can be performed without causing problems such as poor punching or poor stitching due to poor punching. Further, by placing the sheet material 2 on the mounting table 9, the sensor lever 11 rotates and blocks the sheet sensor 13 to detect the presence or absence of the sheet material 2.

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 binding section, 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. Note that a plurality of stoppers 13a and 13b may be provided, and it goes without saying that they may be configured to be movable.

Next, the punching process will be explained. As shown in FIGS. 9 and 10, the punch 20 is supported by guides 22 and 23 that form a pair with the die 10, and the reason why each of the guides 22 and 23 is composed of three pieces is due to manufacturing considerations. This upper and lower independent structure, which may be composed of one piece each, is intended to enable the resin ring 6 to be pulled out to the entrance side in a state where it is bound to 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. By pushing down the handle 16, the punch 2o is lowered and raised by a cam mechanism configured together with the shaft 17, and the sheet material 2 is perforated.

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 conveyance roller 40b descends under its own weight, and the lower conveyance roller 4
Together with 0a, the sheet material 2 is pressed down to enable stable conveyance. At this time, the bin 41c is fixed to the pickup lever 41 so that the pickup lever 41 does not return.
is configured to be held by a claw 46a at the tip of the lock arm 46.

After punching the sheet material 2, the handle 16 is pulled up to pull out the punch 20 from the sheet material 2. At this time, the sheet material 2 is lifted by the friction between the punch 20 and the sheet material 2, and is pushed into the guide 23. If the sheet material 2 is pulled out after hitting the stopper 13, the sheet material 2 is pulled diagonally.
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, or is lowered when 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 collapsing 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 conveying roller 40a and the upper conveying roller 40b are simultaneously driven to convey the sheet material 2.
, 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 conveyed sheet material 2 is sent to the ring opening section via the conveyance 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, 6ib that detect the sizes of the upper support member 52, the lower support member 56, gear trains 53, 57, motors 55, 59, and resin ring 6 for driving them, respectively.
It consists of departments, etc.

As mentioned above, by sandwiching the resin ring 6 between the upper support member 52 and the ring sensor lever 60,
The size of the resin ring 6 to be used is recognized and the opening amount of the resin ring 6 is determined. At this time, the resin song 6 used
The opening amount differs 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 52
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 an opening operation at the same time as the punching operation is completed, but the timing of this opening is set when the sheet material 2 being conveyed has been conveyed to a specified position. You can do whatever you want until then. This open state is shown in FIG. 6, but regarding the opening amount 72 of the resin ring 6 and the position 73 of the ring tip, the resin ring 6 is an elastic member, and the elasticity 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 ring tip position W73. 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 penetrates 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 the direction of closing. Finally, the bound sheet material 2 is pulled out toward the front side, but the regulating member 71 and the ring entrance regulating plate 51 are configured to be rotatable, so that they do not get in the way of the drawing operation of the sheet material 2. There isn't.

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, sheet material stitching in automatic mode can be performed 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 ring 6. It will be stitched together. Also, when you want to add or replace sheet materials 2 to sheet materials 2 that have been bound in advance,
Manual mode will be used instead of automatic mode.

To perform stitching in manual mode, first rotate the stitching means R shown in FIG. 1 clockwise about the fulcrum 75, and
It is held at the position shown in the figure 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. The auxiliary guide cover 7 is attached to the proper position of the sheet material binding device 1.
9 is also rotated counterclockwise about the shaft 82, and the 15th
The position will be as shown in the figure. In the automatic mode, this auxiliary guide cover 79 is held in the position shown in FIG. 1 in conjunction with the cover (not shown) of the binding means R, and in the manual mode, it is held in the position shown in FIG. 15 by an elastic member (not shown). Move to the indicated position.

Next, the actual stitching work will be explained.

First, the resin ring 6 used for stitching is 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, insert the perforated part into the opened claw part 6a of the resin ring 6 at any time.
After inserting the necessary sheet material 2, the resin ring 6 is closed and the sheet material 2 is pulled out to complete the binding operation. When inserting the sheet material 2 into the resin ring 6, an auxiliary guide cover 79 is used to insert the sheet material 2 into the resin ring 6, as shown in FIG. Work can be done easily.

Since the ring sensors 61a and 61b are attached to the sheet material automatic machine mounting device B, they cannot be used when the binding means R is rotated and the manual mode is turned off.

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

Also, when adding or replacing the sheet material 2, as shown in FIG. 16, the upper support member 5
The sheet material 2 is set so as to be placed under the sheet material 2, and the resin ring 6 is opened and closed and the sheet material 2 is punched in the same manner as described above to add and replace the sheet material 2.

(G) As described in detail, according to the present invention, the sheet material regulating means for regulating the thickness of the sheet material inserted into the perforating means is provided on the upstream side of the perforating means, so that the operator can perform the perforation. The possible number or thickness of sheet materials can be accurately determined, and it is possible to prevent poor drilling due to an excessive number of sheet materials.

Also, when taking out sheet material after stitching,
Since the sheet material regulating means is retracted from the sheet material conveyance path, it becomes possible to take out the sheet material without any resistance.
