Detailed Description of the Invention [Technical Field] The present invention relates to a sheet material conveying and processing system, more specifically, a sheet material conveying and processing system that conveys a sheet material through a processing area of a processing machine such as a press machine, and processes a sheet material in this processing area. Regarding conveyance processing systems.

BACKGROUND TECHNOLOGY> For example, in the production of dry battery cases, etc., a metal sheet material is press-formed to form a preformed body of a desired shape, and this preformed body is further subjected to the forming process described in b. It forms a cylindrical case with one end open. In this case, due to the formation of a plurality of preforms from a single band-shaped sheet material, etc., the processing area of the press machine, that is, the processing area that exists between the stationary lower part and the movable upper part of the press machine. It is necessary to advance the sheet material in predetermined amounts intermittently through the tube. That is, during the processing period when the movable upper part of the press actually acts on the sheet material to perform press forming, the sheet material is kept stationary, and during the non-processing period when the movable upper part of the press does not act on the sheet material, this non-working period is used. Sheet material for each processing period? It is necessary to move it forward by a predetermined amount. In order to perform press forming continuously and with high efficiency, it is necessary to advance the next sheet material into the processing area after completing the processing of the previous sheet material, and thus to convey the sheet materials one after another through the processing area. is important. In such a case, if the press is in a non-operating state after the previous sheet material has been processed and until the leading end of the sheet material is fed into the processing area, the next sheet may be In order to position the leading end of the material in the processing area, it is necessary to configure the movable upper part to be in a non-processing state where it does not act on the sheet material during the processing machine's stop time, and this positioning depends on the processing speed of the sheet material. It is desirable to always be in an unprocessed state regardless of the

An object of the present invention is to provide a sheet material conveying and processing system that can be advanced into a processing area of

<Preferred Specific Example of the Invention> Hereinafter, a specific example of a sheet material conveying and processing system constructed according to the present invention will be described with reference to the accompanying drawings.

First, referring to FIG. 1, the illustrated sheet material conveyance processing system includes a sheet material supply mechanism 2, an intermittent feeding means 4, and a processing machine 6. Illustrated sheet material supply mechanism 2
(described in detail later) includes a sheet material supply means 8 and a conveyance means 10f disposed downstream of the sheet material supply means 8. Sheet member supply means 5Fi pair of rows 212
m and 12b, and a pair of rollers 12 & and 1
2b is rotatably attached to the supply unit 14.

The supply unit 14 is attached to a sheet material storage section 16, and a belt-shaped metal sheet material 17 wound into a cylindrical shape is rotatably supported in the sheet material storage section 16. In the specific example, one roller 12m of the pair of rollers constitutes a driving roller, and this roller 12a is drivingly connected to a sheet material supply driving source 18, such as an electric motor, through a suitable transmission means. Such roller pair 12a and 12b
nips the sheet material and selectively forces it into an active and a non-active state as described below. That is, roller pair 12
m and 12b are activated when the drive source 18 is actuated to move the sheet material forward and thus towards the conveying means 10, whereas they are deactivated when the drive source 18 is stopped and prevent the feeding of the sheet material. Stop. In a specific example,
The drive source 18 is composed of a variable electric motor, which rotates at three speeds: relatively low speed, relatively high speed, and medium speed between relatively low speed and relatively high speed based on a signal from a loop detection means (described later). Due to this, the roller pairs IZa and 12b rotate at a relatively low speed in the first operation state, and in the third operation state they rotate at a relatively high speed.
and a second operating state in which it rotates at an intermediate speed between a relatively low speed and a relatively high speed.

Further, the conveying means 10 is composed of a pair of rollers including an upper roller 220 disposed above the sheet material conveying path and a lower roller 22 disposed below the sheet material conveying path. At least one of the upper roller 20 and the lower roller 22, in the specific example the lower roller 22, is coupled to a sheet material transport drive source 24, such as an electric motor. Further, at least one of the upper roller 20 and the lower roller 22, in the specific example the upper roller 20, moves up and down in the vertical direction between an active position shown by a solid line in FIG. 1 and a non-working position shown by a two-dot chain line in FIG. It is layered freely.

An actuator 26, such as a hydraulic cylinder mechanism or a solenoid, is connected to the upper roller 20, and when the actuator 26 is energized, the upper roller 20 is positioned in the operating position and cooperates with the lower roller 22. When the actuator 26 is deenergized, the upper roller 20 is positioned in the non-active position spaced from the lower roller 22 to release the upper We nip condition. The conveying means 10 having such a configuration can be selectively brought into an active state and a non-active state, as will be described later. That is, the conveying means 10
is activated when the actuator 26 is energized and the drive source 24 is activated, and the upper roller 20 and the lower roller 22
Is the sheet material nipped? movement as required, while actuator 26 is deenergized and drive source 24
When it stops, it becomes inactive and does not act effectively on the sheet material and stops its movement. In a specific example, the drive source 24 is constituted by an electric motor capable of forward and reverse rotation;
When the driving source 24 is rotating in the normal direction, the sheet material is fed toward the intermittent feeding means 4, and when the drive source 24 is rotating in the reverse direction in the operating state, the sheet material is fed to the first cutting means (described later).
Send it to.

An intermittent feeding means 4 disposed downstream of the sheet material supply mechanism 2 has an upper gripping means 28 disposed above the sheet material conveyance path and a lower gripping means 28 disposed below the sheet material conveyance path. The gripping means 30 are known per se.

In particular embodiments, the lower gripping means 30 is configured to be selectively positioned between an upper active position and a lower non-active position by the action of an actuator 32, such as a hydraulic cylinder mechanism. Further, the upper gripping means 28 reciprocates in the conveyance direction of the sheet material, and when moving forward, the lower gripping means 30
It is configured to move forward close to the lower gripping means 30 during the backward movement, and to move back away from the lower gripping means 30 during the backward movement, that is, to be positioned above the lower gripping means 30 than during the forward movement. Therefore, when the actuator 32 is energized and the lower gripping means 30 is in the operating position, the upper gripping means 28 cooperates with the lower gripping means 30 during forward movement of the upper gripping means 28, as will be readily understood. The upper gripping means 28 effectively acts on the sheet material existing between the two to advance the sheet material toward the processing machine 6, while when the upper gripping means 28 moves back, the upper gripping means 28 removes the sheet material existing between the two. There is no movement of sheet material apart. Further, when the actuator 32 is deenergized and the lower gripping means 30 is in the non-operating position, the upper gripping means 28 does not effectively act on the sheet material existing between them when the upper gripping means 28 reciprocates. , without causing any movement of the sheet material. The intermittent feeding means 4 having such a configuration can be selectively brought into an operative state and a non-operative state. That is, the intermittent feeding means 4 enters the operating state when the lower gripping means 30 is positioned at the operating position by the action of the actuator 32, and the upper gripping means 28 and the lower gripping means 3
The sheet material existing between 0 and 0 is advanced toward the processing machine 6 by a predetermined amount (the amount of movement of the upper gripping means 28 when moving forward becomes the amount of advance of the sheet material), and the lower gripping means 30 is moved forward by the action of the actuator 320. When it is positioned in the non-operative position, it becomes non-operative and does not effectively act on the sheet material existing between the upper gripping means 28 and the lower gripping means 30 and stops its movement.

The upper gripping means 28 of the intermittent feeding means 4 is reciprocated in synchronization with the movement of the processing machine 6, as will be described later.

The processing machine 6 arranged downstream of the intermittent feeding means 4 is, in a specific example, constituted by a press machine having a stationary lower part 34 containing a forming tool and a movable upper part 36 containing a forming tool. A processing area is defined between the stationary lower part 34 and the movable upper part 36 through which the sheet material is fed. The movable upper part 36 is configured to be moved up and down in the vertical direction relative to the stationary lower part 34, and is located between the uppermost position shown by a solid line in FIG. 1 and the lowermost position shown by a two-dot chain line in FIG. is reciprocated. To explain further, during the period when the movable upper part 36 is located below the predetermined position, that is, during the processing period,
The forming tool of the movable upper part 36 and the forming tool of the stationary lower part 34 act on the sheet material present in the processing area to apply press forming (the processing machine 6 is in the processing state). On the other hand, when the movable upper part 36 is located above the predetermined position, that is, during the non-processing period, the forming tool of the movable upper part 36 is separated upward from the sheet material existing in the processing area and acts on the sheet material. No (processing machine 6 is inactive). The processing period and the non-processing period 1' of the processing machine 6 will be explained with reference to FIG. 2 as well as FIG. 1. FIG. 2 shows a crank 3 provided in an elevating mechanism for moving the movable upper part 36 of the processing machine 6 up and down.
Fig. 8 schematically shows the rotational movement of 8; The crank 38 is
The processing machine 6 is rotated at a constant speed in the direction shown by an arrow 40 (FIG. 2) by the action of a drive source 39 (FIG. 3) of the processing machine 6 such as an electric motor. During such rotation, when the crank 38 reaches the top dead center indicated by the symbol A, the movable upper portion 36 is located at the uppermost position indicated by the solid line in FIG. It is located at the lowest position indicated by the two-dot chain line in FIG. For example, while the crank 38 rotates from the angular position indicated by the symbol C through the bottom dead center B to the angular position indicated by the symbol, the forming tool of the movable upper part 36 and the forming tool of the stationary lower part 34 are in the machining area. The crank 38 moves from the angular position indicated by the symbol to pass through the top dead center A and undergoes an angular displacement fi! indicated by the symbol C. During rotation to t, the forming tool of the movable upper part 36 separates from the sheet material present in the processing area. That is, the crank 38 moves from the angular position indicated by C to the bottom dead center B.
The processing machine 6 is in the machining period (that is, the processing machine 6 is in the processing state) while the crank 38 rotates from the angular position indicated by the symbol to the top dead center At. - during rotation to the angular position indicated by C,
The processing machine is in a non-processing period (that is, the processing machine 6 is in a non-processing state). The processing machine 6 having such a configuration can be selectively brought into an operative state and a non-operative state. That is, when the drive source 39 is activated, the processing machine 6 enters the operating state, and the
The rotation of the /38 repeats the processing period and the non-processing period to perform press forming on the sheet material existing in the processing area, and when the drive source 39 stops, it becomes inactive and the movable upper part 36 moves up and down. is stopped and press forming of the sheet material is stopped.

In the specific example, the upper gripping means 28 of the intermittent feeding means 4 is reciprocated as described above by the action of the drive source 39 (FIG. 3) of the processing machine 6, and the movable upper part 36 of the processing machine 6
The intermittent feeding means 4 advances the sheet material by a predetermined amount in synchronization with the vertical movement of the sheet material.

To explain further, with reference to FIGS. 1 and 2, for example, the crank 38 moves from the angular position indicated by symbol E (that is, the angular position rotated 270 degrees from the top dead center A) to the top dead center A'ft.
: through the angular position indicated by the symbol F (i.e., from top dead center A to 9
During rotation over an angular range of 180 degrees to the angular position rotated by 0 degrees, the upper gripping means 28 of the intermittent feeding means 4 is advanced, and the crank 38 moves from the angular position indicated by the symbol F to the bottom dead center B. said upper gripping means 28 during rotation through an angular range of 180 degrees to the angular position indicated by the symbol E.
is forced to retreat. Therefore, in the operating state of the intermittent feeding means 4, while the crank 38 rotates from the angular position indicated by the symbol E to the position indicated by the symbol F (during this period, the processing machine 6
is in the non-processing period), the intermittent feeding means 4 advances the sheet material toward the processing area of the processing machine 6, and the crank 3
8 rotates from the angular position indicated by the symbol F to the angular position f indicated by the symbol E (during this period, the processing machine 6 is immediately before the end of the non-processing period, immediately after the processing period and the start of the non-processing period),
The intermittent feeding means 4 completely stops feeding the sheet material. Thus, in the operating state, the intermittent feeding means 4 feeds a predetermined amount of sheet material to the processing area of the processing machine 6 during each non-processing period of the processing machine 6. In a specific example, the drive source 39 of the processing machine 6 is composed of a variable electric motor, and therefore a desired processing speed can be obtained by changing the rotational speed of the electric motor. In the specific example, the upper gripping means 28 of the intermittent feeding means 4 is configured to be reciprocated by the action of the drive source 39 of the processing machine 6;
A dedicated drive source may be provided separately from 9, and the upper gripping means 28 may be reciprocated as required in synchronization with the vertical movement of the movable upper part 36 of the processing machine 6 by the action of the drive source. .

The illustrated sheet material conveyance processing system further includes a guide table 42 and a first cutting means 44 disposed in relation to the conveyance means 10 of the sheet material supply mechanism 2, and a processing machine 6.
A second cutting means 46 is provided, which is arranged in association with the second cutting means 46 . Referring again to FIG. 1, the guide table 42 is disposed upstream of the conveyance means 10. The guide table 42 is rotatably mounted at its center when viewed in the sheet material conveyance direction, and an actuator 48 such as a fluid pressure cylinder mechanism is connected to the rear end when viewed in the sheet material conveyance direction. As will be described later, the guide table 42 is selectively positioned in a first position shown by a solid line in FIG. 1 and a second position shown by a two-dot chain line in FIG. 1 by the action of an actuator 480, as will be described later. That is, when the actuator 48 is deenergized, the guide table 42 is in the first position shown in solid lines in FIG. When the actuator 48 is energized, the guide table 42 is pivoted counterclockwise in FIG. The sheet material f! from the conveying means 10 as will be described later is conveyed by the guiding portion 42 & defined on the lower surface of the leading end. then guide the end towards the first cutting means 44 .

The first cutting means 44 is arranged below the guide table 44 . Although not shown, the first cutting means 44 is constituted by a known cutting device having a stationary shearing blade and a rotating shearing blade, and the rotating shearing blade is connected to a cutting drive source 50 such as an electric motor It is rotated in a predetermined direction by the action shown in Fig. 3). The first cutting means 44 can be selectively brought into an operative state and a non-operative state, as will be described later. That is, the first cutting means 44 is activated when the drive source 50 is activated, and the first cutting means 44 has a stationary shearing blade and a rotating shearing blade (none of which are shown).
As will be described later, the sheet material is cut into small pieces by the cooperative action of - When the blade drive source 50 stops, it becomes inactive υ,
The rotating shear blade stops rotating to stop cutting the sheet material.

A pair of guide plates 52 are provided on the upstream side of the first cutting means 44.
and 54 are disposed, and a pair of conveyance rollers 56 and 58 are further disposed upstream of the guide plates 52 and 54.

In the specific example, one of the pair of conveyance rollers 256 is drivingly connected to the drive source 24 of the conveyance means 10 . Therefore, when the guide table 42 is positioned at the second position and the conveying means 10 feeds the sheet material toward the first cutting means 44, the sheet material is transferred to the guide section located at the tip of the guide table 42. 42a and is conveyed toward the conveyance rollers 56 and 58, and further conveyed to the first cutting means 44 through the guide plates 52 and 54 by the action of the conveyance rollers 56 and 58.

Further, the second cutting means 46 is arranged downstream of the processing machine 6. The second cutting means 46 is connected to the first cutting means 4
4, with a stationary shear blade (not shown)
and a rotating shearing blade (not shown) that is rotated in a predetermined direction by the action of a cutting drive source 60 (FIG. 3) such as an electric motor.
have.

This second cutting means 46 can also be selectively brought into an operative state and a non-operative state, as will be described later. That is, the second cutting means 46 is activated when the drive source 60 is activated.
By the cooperative action of the stationary shearing blade and the rotating shearing blade, the processed sheet material is cut into small pieces as will be described later.
When it stops, it becomes inactive and the rotary shear blade stops rotating and stops cutting the sheet material. A pair of guide plates 62 and 64 are arranged upstream of the second cutting means 46 for guiding the sheet material processed in the processing area of the processing machine 6 to the second cutting means 46.

In the exemplary sheet material conveying and processing system, the following 9 detection means are provided to control the operation of the various operating components described above.

That is, on the upstream side of the second cutting means 46 and immediately downstream of the processing machine 6, a first sheet material detection means 66 for detecting the sheet material is arranged. A second sheet material detection means 68 for detecting sheet material is provided upstream of the conveyance means 10 and immediately downstream of the sheet material supply means 8. A third sheet material detection means 70 for detecting sheet material is provided downstream of the conveyance means 10 and immediately upstream of the intermittent feeding means 4. Information table 4
A fourth sheet material detecting means 72 for detecting sheet material is disposed downstream of the conveying means 2 and immediately upstream of the conveying means 10. Further, a fifth sheet material detection means 74 for detecting sheet material is provided upstream of the first cutting means 44 and downstream of the conveying rollers 56 and 58.

Furthermore, on the downstream side of the sheet material supply means 8 and on the conveying means 1
A loop detecting means 76 for detecting the loop state of the sheet material is disposed on the upstream side of the sheet material at a location where a desired loop is generated in the sheet material. In a specific example, as shown in FIG. 3, the loop detecting means 76 includes an excessive loop detector 78 that detects an excessive loop state, which will be described later.
A first under-reduction detector 80 for detecting a first loop under-reduction condition, which will be described later. It includes a second under-insufficiency detector 82 that detects a second loop under-insufficient state, which will be described later, and a third under-insufficient detector 84, which detects a third loop under-insufficient state, which will be described later. Immediately downstream of the loop detection means 76, a loop abnormality detection means 86 is provided to detect any abnormalities in the loop state of the sheet material. These detection means (including detectors 78, 80° 82 and 86) 66, 68, 70,
72゜74.76 and 86 are optical devices known per se, which have a light emitting element and a light receiving element that receives reflected light emitted from the light emitting element and reflected by the sheet material when the sheet material is in a required state. It consists of a detector. The sheet material conveyance processing system described above further includes a second
As shown in the drawings and FIG. 3, it is provided with an angular position detection means 88 which is disposed in relation to the crank 38 and detects a specific angular position (in the specific example, the angular position indicated by the symbol E) of the crank 38. . The angular position detecting means 88 in the specific example includes means for generating a pulse signal every time the crank 38 reaches an angular position indicated by the symbol E.

Referring to FIG. 3, the sheet material conveyance processing system includes a control means 90 for controlling the operation of various operating components such as the processing machine 6 based on output signals of the various detection means described above.
It is equipped with The control means 90 in the specific example is composed of a microprocessor incorporating a first timer means 92, a second timer means 93, and a storage means 94.

The operation procedure of the sheet material conveyance processing system described above will be explained with reference to FIG. 4, which is a time chart showing the operation procedure of the sheet material conveyance processing system of a specific example, together with FIGS. 1 to 3. In a specific example, as will be described in detail later, the sheet material supply mechanism 2 includes a plurality of sheet material storage sections 16 (in a specific example, a plurality of sheet material storage sections 16 are arranged in a direction perpendicular to the plane of the paper in FIG. 1). The interior of the plurality of sheet material storage units is placed on a support stand 95, and the support stand 95 is reciprocated in a direction perpendicular to the plane of the paper in FIG. 1 by the action of a moving drive source 96 such as an electric motor. It is configured. In connection with this, each sheet material storage section 16 is equipped with a sheet material supplying means 8, and furthermore, when the sheet material storage section 16 containing the sheet material to be supplied is at a required position. A position detecting means 98 is attached to detect this.

The control by the control means 90 described above is as follows.

(1) First, the start switch 100 (FIG. 3) of the sheet material conveying and processing system is manually closed.

In this way, the entire system becomes operational, and first, the control means 90 energizes the S power source 96 in response to a signal from the start switch 100.

Thus, the support base 95 is moved as required by the action of the drive source 96.

(1) When the support base 95 is moved and the desired sheet material storage section 16 is moved to the position detection means 98, the position detection means 98 detects this and generates an output signal. In this way, the control means 90 deenergizes the drive source 96 and energizes the drive source 18 at the same time based on the output signal from the position detection means 98. When the drive source 96 is deenergized, the movement of the support base 95 is stopped and the desired sheet material storage section 16 is positioned at a predetermined position. On the other hand, when the drive source 18 is energized at the same time, the sheet material supply means 8 comes into operation, and the roller pair 1
21L and 12b are rotated in a predetermined direction. In the specific example, the drive source 18 is rotated at a relatively constant speed at this time, and the sheet material supply means 8 is in the third operating state. Thus, the sheet material 1 supported in the sheet material storage section 16
The tip side of the paper 7 is carried out by the action of the pair of rollers 12a and 12b, and is fed toward the conveying means 10 while being guided by a guide member (not shown).

0:1) When the sheet material is fed as described above and its leading edge is conveyed to the third sheet material detection means 70, the third sheet material detection means 70 detects this and outputs an output signal. generate. Thus, the output signal from the third sheet material detection means 70 causes the control means 90 to energize the actuator 26 and the drive source 24, and also to activate the loop detection means 7.
6 is put into operation (at this time, the drive source 24 is rotated in the forward direction). When the actuator 26 and the drive source 24 are energized, the conveying means 10 is operative, the upper roller 20 is positioned in the operative position, and the upper roller 20 and the lower roller 22 move the leading edge of the sheet material between them. Nip the part. Thus, by normal rotation of the drive source 24, the sheet material is fed through the processing area existing between the upper gripping means 28 and the lower gripping means 30 of the intermittent feed means 4, and between the stationary lower part 34 and the movable upper part 36 of the processing machine. Ru. Also, at this time, since the loop detection means 76 is in the operating state, the control means 90 controls the sheet material supply means 8 based on the signal from the loop detection means 76.
t-control. The control of the sheet material supply means 8 using the signal from the loop detection means 76 will be described later. Therefore, in connection with the feeding of the sheet material by the conveying means 10, the sheet material supplying means 8 is selectively put into an operating state (first operating state, second operating state, or third operating state) and a non-operating state. The sheet material in the sheet material storage section 16 is conveyed out in accordance with the amount of advance of the sheet material by the conveyance means 10.

Mosquito) When the sheet material is thus fed and its leading end is conveyed to the first sheet material detection means 66, the first sheet material detection means 66 detects this and generates an output signal. Thus, the output signal from the first sheet material detection means 66 causes the control means 90 to control the actuator 26 and the drive source 24.
At the same time, the actuator 32 and the drive sources 39 and 60 are energized (at this time, the loop detection means 76 continues to be kept in the operating state). When the actuator 26 and the drive source 24 are de-energized, the upper roller 20 is positioned in a non-active position, the drive source 24 is stopped, and the conveying means 10 is placed in a non-active state. On the other hand, when the drive source 39 is energized at the same time, the processing machine 6 becomes operational, the movable upper part 36 is moved up and down as required, and the processing period and non-processing period are repeated. In synchronization with the vertical movement of the movable upper part 36, the upper gripping means 28 of the intermittent feeding means 4 is also reciprocated as required.

Further, when the actuator 32 is energized, the intermittent feeding means 4 is brought into operation, and the lower gripping means 4 is positioned in the operation position. Furthermore, when the drive source 60 is energized, the second cutting means 46 is activated and a rotating shear blade (not shown) is rotated. Thus, when the upper gripping means 28 of the intermittent feeding means 4 advances, the leading end side of the sheet material is transferred to the processing machine 6.
The sheet material is advanced by a predetermined amount toward the processing area of the processing machine 6 each time the processing machine 6 is not processed, and the sheet material fed to the processing area by the action of the intermittent feeding means 40 is press-formed at each processing time of the processing machine 6. The unnecessary portion of the sheet material after being processed in the processing area is cut into small pieces by the action of the second cutting means 46.

During the above-mentioned processing by the processing machine 6, the loop detection means 76 is kept in an activated state, so that the control means 90 is activated in connection with the advancement of the sheet material by the intermittent feeding means 4.
controls the operation of the sheet material supply means 8 based on the signal from the loop detection means 76 as follows. To explain further,
When the leading end side of the sheet material is advanced by the action of the intermittent feeding means 4 and the loop state becomes relatively insufficient (a first loop insufficient state), the first insufficient detector 80 detects the sheet material. and generate an output signal. Thus,
Based on the output signal from the first shortage detector 80, the control means 90 causes the drive source 18 to rotate at a relatively low speed, thereby causing the pair of rollers 121 and 12b of the sheet material supply means 4 to rotate.
is rotated at a relatively low speed (the sheet material supply means 4 is rotated at a relatively low speed).
), the sheet material in the sheet material storage section 16 is thus discharged at a relatively low speed. Despite the conveyance of the sheet material by the action of the sheet material feeding means 40 in the above-mentioned first operating state, the loop state of the sheet material becomes even smaller than the first loop insufficient state (
the second loop is in an under-under condition) and the second under-under condition detector 8
2 detects the sheet material and generates an output signal. In this way, the control means 90 rotates the drive source 18 at a medium speed (a speed intermediate between the relatively low speed described above and the relatively high speed described later) based on the output signal from the second underdetection detector 82. Roller pair 12a and 1 of sheet material supply means 4
2b is rotated at a medium speed (the sheet material supply means 4 is in the second operating state), and the sheet material in the sheet material storage section 16 is thus delivered at a medium speed. Furthermore, despite the sheet material being carried out by the action of the sheet material supplying means 40 in the second operating state, the loop state of the sheet material becomes even smaller than the second loop insufficient state (the third loop insufficient state). condition), a third underdetector 84 detects the sheet material and generates an output signal. Thus,
Based on the output signal from the third under-supply detector 84, the control means 90 causes the drive source 18 to rotate at a relatively high speed, thereby causing the sheet material supply means 80 roller pairs 12& and 12b to rotate.
is rotated at a relatively high speed (the sheet material supply means 4 is rotated at a relatively high speed).
), and the sheet material in the sheet material storage section 16 is thus transported out at a relatively high speed. On the other hand, despite the advance of the sheet material by the intermittent feeding means 4, the sheet material is moved forward by the sheet material feeding means 8 in the operating state (first operating state, second operating state, or third operating state). When the sheet material is unloaded and becomes over-looped (over-loop condition), over-loop detector 78 detects the sheet material and generates an output signal. Thus, based on the output signal from the overload detector 78, the control means 90 de-energizes the drive source 18, thereby causing the roller pair 12 &
And the rotation of 12b is stopped (sheet material supply means 8 becomes inactive).

As described above, during processing by the processing machine 6, the sheet material supplying means 8 is selectively put into the operating state (the first operating state, the first operating state, etc.) in relation to the advancement of the sheet material by the intermittent feeding means 8. (2) active state or a third active state) and a non-active state, thus maintaining the required loop condition regardless of advancement of the sheet material. As described above, since the loop detection means 76 is activated during the conveyance of the sheet material by the conveyance means 1o, also at this time, the sheet material supply means 8 is are selectively brought into the active state (first active state, second active state, or third active state) and the non-active state in the same manner as described above, so that the required The loop state is maintained.

(Vl When the above-described processing of the sheet material is performed and all the sheet materials are carried out from the sheet material storage section 16 and the rear end is conveyed to the second sheet material detection means 68, the second sheet material detection means 68 detects this and eliminates the output signal.Then, based on the disappearance of the output signal of the second sheet material detection means 68, the first timer means 92 of the control means 90 is activated, and the first timer means 92 generates an output signal after a predetermined time t1 has passed after the start of operation.Then, based on the output signal from the first timer means 92, the control means 90 deenergizes the drive sources 18 and 39 and the actuator 32, and further causing the loop detection means 76 to be inactive;
At the same time, the drive sources 24 and 96 and the actuator 26 are energized (at this time, the drive source 24 is rotated in the normal direction).

When the drive source 18 is deenergized, the sheet material supply means 8 becomes inactive, and the rotation of the roller pairs 12& and 12b is stopped. At this time, since the loop detection means 76 is also inactive, the control of the sheet material supply means 8 based on the signal from the loop detection means 76 is also stopped. In addition, drive source 3
9 and the actuator 32 are deenergized, the movable upper part 36 of the processing machine 6 is stopped from moving up and down and the reciprocating movement of the upper gripping means 28 of the intermittent feeding means 4 is stopped by the deenergization of the drive source 39. By deenergizing the actuator 32, the lower gripping means 30 of the intermittent feeding means 4 is positioned in the inoperative position, and thus the processing machine 6 and the intermittent feeding means 4 are brought into the inactive state and processing of the sheet material is stopped. be done. The above-mentioned deenergization of the drive source 39 is performed by
In the specific example, this is carried out in conjunction with the rotational movement of the crank 38 (FIG. 2) and the machining speed of the machine 6 in its operating state. To explain further, the storage means 9 of the control means 90
4 stores in advance time T corresponding to various machining speeds. This time T corresponds to the time required for the crank 38 to rotate from the angular position indicated by E (FIG. 2) to a position in which the machine 6 is rendered inactive. The position where the processing machine 6 is brought into a non-working state means that when the drive source 39 is brought into a non-working state at such a position, the movable upper part 36 acts on the sheet material existing in the processing area when the processing machine 6 is stopped. not be in an unprocessed state,
Preferably, as in the specific example, the movable upper part 36 is near the uppermost position shown by the solid line in FIG.
This is the position near the top dead center indicated by . Therefore, as is easily understood, when the processing speed of the processing machine 6 is relatively high, the above-mentioned time T becomes relatively short due to the relatively large inertia force of the movable upper part 36, and the drive The position where the source 39 is deenergized is closer to the angular position indicated by the symbol E. On the other hand, when the processing speed of the processing machine 6 is relatively low, the inertial force of the movable upper part 36 is relatively small. As a result, the time T is relatively long, and the position where the drive source 39 is deenergized is closer to the top dead center indicated by the symbol A. In the embodiment thus constructed, the second sheet material detecting means 68 detects the trailing edge of the sheet material as described above, and the angular position detecting means 88 detects the rear end of the sheet material as described above.
Upon detecting the angular position shown by read out,
After the time T read above has elapsed (i.e., crank 3
8 in the direction indicated by arrow 40 from the angular position indicated by symbol E.
(after being rotated for a time), the drive source 39 is deenergized. As a result, the processing machine 6 becomes inactive as described above, and the processing machine 6 comes to a complete stop with some movement due to the inertia of the movable upper part 36 and the like compared to when the drive source 39 was deenergized. When stopped, the movable upper part 36 of the processing machine 6 is positioned near the uppermost position shown by the solid line in FIG. In this way, the sheet material existing in the processing area can be moved, and when feeding the next new sheet material, the leading end side of this sheet material can be fed through the processing area of the processing machine 6, Continuous processing of multiple sheet materials becomes extremely easy. .

On the other hand, when the drive source 24 and the actuator 26 are energized at the same time, the conveying means 10 becomes operational, and as described above, the upper roller 20 and the lower roller 22 move the leading edge of the sheet material between them. Nip. Thus, the driving source 24
The sheet material is further advanced by normal rotation of the sheet material. At this time,
The drive source 60 continues to be energized and therefore the transport means 10
The sheet material fed by this action is cut into small pieces by the second cutting means 46.

Further, when the drive source 96 is energized, the support stand 95 is moved as required, the sheet material storage section 16 from which all the sheet materials have been carried out is moved from the predetermined position, and a new sheet material is supported. The sheet material accommodating section 16 that is currently in use is moved toward a predetermined position.

υ0 When the support base 95 is moved as described above and the sheet material storage section 16 supporting a new sheet material is moved to the position detection means 98, the position detection means 98
detects this and generates an output signal again. In this way, the control means 90 is controlled by the output signal from the position detection means 98.
deenergizes the drive source 96 again. When the drive source 96 is de-energized, the movement of the support base 95 is stopped, and the sheet material storage section 16 from which all the sheet materials have been carried away moves away from the predetermined position, and a new sheet material is supported by another sheet. The material storage part 16 is positioned in the working position.

(V+1) Next, when the sheet material is fed by the action of the conveyance means 10 and the rear end is conveyed to the fourth sheet material detection means 72, the fourth sheet material detection means 72 detects this and outputs it. Lose the signal. Thus, based on the disappearance of the output signal of the fourth sheet material detection means 72, the control means 90 de-energizes the drive source 601 and at the same time reverses the drive source 24 in the operating state of the conveying means 10 (therefore, the actuator 26 (continues to be energized) and energizes the actuator 48. When the drive source 60 is deenergized, the rotating shearing blade (not shown) stops rotating, and the second cutting means 4
6 becomes inactive. Meanwhile, at the same time, the conveying means 1
When the drive source 24 is reversed in the zero operating state, the upper roller 20 and the lower roller 22 are rotated in the opposite direction to the normal rotation. Also, when the actuator 48 is energized, the guide table 42 is pivoted counterclockwise in FIG. 1 to a second position shown by the two-dot chain line in FIG. In this way, the sheet material that has been moved forward is moved backward by the conveyance means 10, and this sheet member moves toward the pair of conveyance rollers 56 and 58 while being guided by the guide section 42& of the guide table 42 from the rear end side. is,
It is further moved toward the first cutting means 44 by the action of the conveying rollers 56 and 58 (in the specific example, the conveying roller 56 of the pair of conveying rollers is drivingly connected to the drive source 24, and therefore the driving When the source 24 is in reverse, the transport rollers 56 are rotated to move the sheet material towards the first cutting means 44).

(vill) When the sheet material is moved from the rear end side by the action of the conveyance means 10 and the rear end is conveyed to the fifth sheet material detection means 74, the fifth sheet material detection means 74 detects this. Generate an output signal. Then, based on the output signal from the fifth sheet material detection means 74, the control means 90 deenergizes the actuator 48 and simultaneously energizes the drive source 50. When actuator 48 is deenergized,
The guide table 42 is rotated clockwise in FIG. 1 and positioned at the first position shown in solid lines in FIG. Therefore, the information table 42
is positioned in the first position, the sheet material is ensured to be moved towards the first cutting means 44 by the action of the transport rollers 56 and 58). On the other hand, when the drive source 50 is energized at the same time, the first cutting means 44 comes into operation,
The rotating shear blade (not shown) is rotated. Thus,
The unnecessary portion of the sheet material fed by the action of the transport means 10 and the transport rollers 56 and 58 is cut into small pieces by the action of the first cutting means 440.

(iX) The sheet material is fed from the rear end side, and its leading edge (therefore, the rear end when viewed in the backward direction of the sheet material) is the fifth
When the sheet material is conveyed to the sheet material detection means 74, the fifth sheet material detection means 74 detects this and eliminates the output signal. Thus, based on the disappearance of the output signal of the fifth sheet material detection means 74, the control means 90 deenergizes the actuator 26 and the drive source 24, and simultaneously energizes the drive source 18. When actuator 26 and drive source 24 are deenergized, upper roller 20
is positioned at the non-operating position, the drive source 24 is stopped, and the conveying means 10 is brought into the non-operating state again. On the other hand, when the drive source 18 is energized at the same time, the sheet material supply means 8 provided in the sheet material storage section 16 in which the new sheet material is supported is not activated, as described above. Then, this new sheet material is transferred to the conveying means 1.
0. Further, when the fifth sheet material detection means 74 detects the rear end of the sheet material, the second timer means 93 of the control means 90 is activated based on the disappearance of the output signal of the fifth sheet material detection means 74, The second timer means 93 generates an output signal after a predetermined time t2 has elapsed after the start of operation. This predetermined time t2 is the time it takes for the sheet material to fall under its own weight and be cut through by the first cutting means 44 as required. Thus, the second timer means 93
The control means 90 de-energizes the drive source 50 based on the output signal. When the drive source 50 is de-energized, the rotating shear blade (not shown) stops rotating and the first cutting means 44 becomes inactive.

CK) Next, when a new sheet material is fed in the same manner and its leading edge is conveyed to the third detection means 70, the third detection means 70 detects this and generates an output signal. Then, in response to the output signal from the third sheet material detection means 70, the control means 90 again energizes the actuator 26 and the drive source 24t, and causes the loop detection means 76 to be activated. Thereafter, a new sheet material is processed in the same manner as described above, and the above-described procedure is repeated successively for a plurality of sheet materials.

As described above, in the sheet material conveyance processing system described above, a plurality of sheet materials are processed continuously.

In the illustrated example, the loop state becomes abnormally small while the sheet material is advancing (therefore, the third
(the loop becomes even smaller than the loop underload condition), the loop abnormality detection means 86 detects the sheet material and generates an abnormal signal, and the entire system is configured to be inactive based on the abnormal signal. There is.

Next, with reference to FIG. 5 to FIG. 7, the configuration of a preferred example of the main portion of the sheet material supply mechanism 2 in the sheet material conveyance processing system described above will be described in further detail.

Each of the above-described sheet material storage sections 16 is provided with a supply unit 14 equipped with a sheet material supply means 8 having the above-mentioned configuration. The supply unit 14 includes a pair of lower side plates 116 (only one shown in FIG. 5) fixed to the sheet material storage section and an upper side plate 118 (one shown in FIG. 5) rotatably attached to each lower side plate 116. ), and the roller 12 is provided between the lower side plate 116.

In the specific example, as described above, the drive source 18 is constituted by a variable electric motor, which rotates at a relatively low speed, a medium speed, or a relatively high speed based on a signal from the loop detection means 76 during operation. be done.

A support structure 13 is provided approximately in the middle of the support base 102 in the lateral direction.
2 is placed. The illustrated support structure 132 includes a plurality of vertical members 134 and horizontal members 136 interconnected as desired. The support structure 132 includes an outer guide member 138 having a relatively large curve and an inner guide member 14 having a relatively small curve.
0 is attached. In the specific example, the outer guide member 138
A projecting member 1 whose one end is fixed to a vertical member 134 and whose other end is fixed to a horizontal member 136 and projects upward.
In addition, one end of the inner 1111 guide member 140 is fixed to one end of the horizontal member 136, and the other end is vertically attached to the other end of the horizontal member 136. It is installed in an adjustable manner. Therefore, the curved states of the outer guide member 138 and the inner guide member 140 can be adjusted by changing the positions of their other ends. In addition, in the specific example, the fifth
As understood from FIG. 7, the sheet material storage section 1
The support base 95 provided with the support structure 6 is moved laterally through the support structure 132 so that the sheet material supported in the sheet material receptacle 16 located within the support structure 132 is moved toward the outer guide member 138 and the above-mentioned outer guide member 138 . It is fed toward the conveying means 10 (described in detail later) through the inner guide members 140.

An operating shaft 143 is arranged in the longitudinally intermediate portion of the support base 102, and one end side of the operating shaft 143 is rotatably supported by a support member 144. The actuating shaft 143 is formed with a male threaded portion over substantially the entire length extending in the lateral direction. On the other hand, a block member 146 (FIG. 7) is fixed to the lower surface of the support base 95, and the block member 146 is formed with a female thread. The male threaded portion of the operating shaft 143 is screwed into the female threaded portion of this block member 146.

In the supply section of the sheet material supply mechanism 2 having such a configuration, the second sheet material detection means 68 is disposed at one end of the outer guide member 138. Further, a loop detection means 76 is disposed on a protruding member 152 that is provided on the horizontal member 136 and protrudes upward in correspondence with the curved portions of the outer guide member 138 and the inner guide member 140. The loop detecting means 76 includes a mounting member 154 fixed to a protruding member 152, and is mounted on the mounting member 154 in order from above to below: an oversized detector 78, a first undersized detector 80, and a second undersized detector 80.
An under-pronouncement meter 82 and a third under-extent detector 84 are installed. Therefore, when the curved portion of the sheet material approaches the inner surface of the outer guide member 138 (creating an over-loop condition), the over-loop detector 78 detects this and the curved portion of the sheet material approaches the inner surface of the outer guide member 138. Once the curved portion of the sheet material has moved away from the inner surface of the outer guide member 138 (resulting in a second under-loop condition), the first under-underdetector 80 detects this. ), the second under-reduction detector 82 detects this, and also detects a third under-reduction when the curved portion of the sheet material approaches the inner surface of the inner guide member 140 (a third loop under-representation condition). Detector 84 detects this. Further, an abnormality detecting means 86 is disposed at the curved portion of the inner guide member 140. This abnormality detection means 8
6 detects when the curved portion of the sheet material abuts against the inner surface of the inner guide member 140. Furthermore, position detection means 98 are disposed at required positions within the support structure 132 of the support base 102, and on the other hand, a member to be detected 156 is fixed to each sheet material storage section 16. Therefore, when the support base 95 is moved as described above and a desired sheet material storage section 16 is located at a predetermined position within the support structure 132, the position detection means 98 is provided in the corresponding sheet material storage section 16. The detected member 156 is detected. In the specific example, movement stop switches 158 and 160 are further provided at both lateral ends of the support base 102, and protruding pieces 162 are provided at both lateral ends of the support base 95 in correspondence with the movement stop switches 158 and 160. (only one side is shown in FIG. 5).

One of the movement stop switches 158 detects one of the protruding pieces 160 and stops the drive source 96 when the support base 95 moves to the position indicated by the two-dot chain line in FIG. . The other movement stop switch 160 detects the other protruding piece 162 when the support base 95 moves to the position shown in FIG. 6 and the solid line in FIG.
6 is stopped. Therefore, the support stand 95 is usually the sixth
It is moved from the position shown in the figure and shown by the solid line in FIG. 7 through the support structure 132 to the position shown by the two-dot chain line in FIG. In addition, in the specific example, the support stand 95 is the rail 104a.
Stop pieces 164 and 166 are provided at both ends of one rail 104a to prevent it from coming off the rails 104b and 104b (FIG. 7).

Furthermore, the guide plate 1 attached to the supply unit 14
28 is provided with material confirmation means 168 for detecting the sheet material. In order to load the sheet material into the sheet material storage section 16 as desired, the sheet material is first placed on the main support roller 112 and the auxiliary support roller 114, and then its leading edge 9111 is adjusted as desired and the sheet material m Verification means 1
Derive up to 68. Thus, the material confirmation means 168
detects this and moves the support base 95 as described above, only the sheet material for which the material confirmation means 168 has detected is positioned at a predetermined position within the support structure 132 as described above. You will be able to do it.

For example, in the specific example, the loop detecting means 76 is composed of an overdetector 78, a first underdetector 80, a second underdetector 82, and a third underdetector 84; The loop detecting means 76 can also be composed of an overdetector and an underdetector, or an overdetector, a first underdetector, and a second underdetector. When the loop detecting means 76 is composed of an oversized detector and an undersized detector, when the oversized detector detects the sheet material, the drive source 18 is stopped (the sheet material supply means 8 is rendered inactive), and the When the detector detects the sheet material, the drive source 18 may be activated (the sheet material supply means 8 may be brought into operation). In addition, when the loop detection means 76 is composed of an oversized detector, a first undersized detector, and a second undersized detector, when the oversized detector detects the sheet material, the drive source 18 is stopped (sheet material supplying means 8t - is brought into a non-active state), when the first under-detector detects sheet material, the drive source 18 is rotated at a relatively low speed (bringing the sheet material supply means 8 into a first working state); Furthermore, when the second shortage detector detects the sheet material, the drive source 18 may be rotated at a relatively high speed (the sheet material supply means El may be brought into the second operating state).
