Description

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 Art> 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 a desired forming process to form one end. forms an open cylindrical case. 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. It is necessary to advance the sheet material by a predetermined amount at each processing time. In order to perform press forming continuously and with high efficiency, the next sheet material is advanced into the processing area after the previous sheet material has been processed.
It is thus important to transport sheet material one after the other through the processing area. In such a case, if the press is in a non-operating state after the processing of the previous sheet material is completed and until the leading edge of the next sheet material is fed into the processing area, the next sheet material In order to position the tip of the machine in the processing area, it is necessary to configure it so that the movable upper part is in a non-processing state where it does not act on the sheet material while the processing machine is stopped, 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 situation.

<Object of the Invention> The present invention has been made in view of the above-mentioned facts, and its main purpose is to stop the processing machine in a non-processing state after finishing processing the previous sheet material, so that the next sheet material can be processed by the processing machine. 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

<Summary of the Invention> According to the present invention, there is provided a sheet material supply mechanism for supplying a belt-shaped sheet material;
a processing machine that selectively processes the sheet material in the processing area by repeating a processing period in which the sheet material is in a processing state and a non-processing period in which the sheet material is not acted on; forced into a state of non-action and a state of action,
The sheet material does not effectively act on the sheet member in the non-working state, and in the working state, the sheet material can be fed by a predetermined amount toward the processing machine each time the processing machine is not processing. An intermittent feeding means disposed between the feeding mechanism and the processing machine, and a control means for controlling the processing machine, and the control means controls the processing when the sheet material feeding is finished. There is provided a sheet material conveying and processing system characterized in that the processing machine is brought into the non-working state based on the processing speed of the processing machine in the working state so that the processing machine is in the non-working state when the machine is stopped.

<Preferred Specific Example of the Invention> Hereinafter, a specific example of a sheet material conveying and processing system configured 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. The illustrated sheet material supply mechanism 2 (described in detail later) includes a sheet material supply means 8 and a conveyance means 10 disposed downstream of the sheet material supply means 8. The sheet member supply means 8 includes a pair of rollers 12a and 12.
b, and a pair of rollers 12a and 12b.
is rotatably attached to the supply unit 14. The supply unit 14 is attached to a sheet material storage section 16, and a cylindrically wound band-shaped metal sheet material 17 is rotatably supported in the sheet material storage section 16. In a specific example, one roller 12a of the pair of rollers constitutes a driving roller,
This roller 12a is drivingly connected to a sheet material supply drive source 18, such as an electric motor, via 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,
The pair of rollers 12a and 12b is activated when the drive source 18 is actuated to move the sheet material forward and thus towards the conveying means 10, while it is inactive when the drive source 18 is stopped and moves the sheet material forward and thus towards the conveying means 10. Stop feeding. In the specific example, the drive source 1
8 is composed of a variable electric motor, which operates at a relatively low speed based on a signal from a loop detection means (described later).
The roller pair 12a and 12b rotates at a relatively low speed in the operating state. A third operating state in which it rotates 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 conveyance means 10 is constituted by a roller pair consisting of an upper roller 20 disposed above the sheet material conveyance path and a lower roller 22 disposed below the sheet material conveyance path. At least one of the upper roller 20 and the lower roller 22, in the particular embodiment, the lower roller 22, is drivingly connected to a sheet material transport drive source 24, such as an electric motor. In addition, at least one of the upper roller 20 and the lower roller 22, in the specific example the upper roller 20, is vertically movable between an operating position shown by a solid line in FIG. 1 and a non-working position shown by a two-dot chain line in FIG. is installed on. 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 working position and the lower roller 22
When the actuator 26 is deenergized, the upper roller 20
is located in the inactive position away from the lower roller 22 to release the 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 differential 26 is energized and the drive source 24 is actuated so that the upper roller 20 and the lower roller 22 nip the sheet material to move the sheet material as desired, while When the actuator 26 is de-energized and the drive source 24 is stopped, it becomes inactive and does not effectively act on the sheet material, stopping its movement. In the specific example, drive source 2
4 is constituted by an electric motor which can rotate in both directions, and in connection with this, the conveying means 10 transports the sheet material towards the intermittent feeding means 4 when the drive source 24 is rotating in the normal direction in the active state. In operation, when the drive source 24 is in reverse, the sheet material is fed towards a first cutting means (described below).

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 includes an actuator 32 such as a hydraulic cylinder mechanism.
The actuator is configured to be selectively positioned between an upper working position and a lower non-working position by the action of the above. Further, the upper gripping means 28 is
It reciprocates in the conveyance direction of the sheet material, moves forward close to the lower gripping means 30 during forward movement, and retreats away from the lower gripping means 30 during forward movement, that is, positioned above the lower gripping means 30 during forward movement. It is composed of 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 forward, the upper gripping means 28 moves the sheet material existing between the two. There is no movement of the sheet material away from the material. 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 is activated when the lower gripping means 30 is positioned at the operational position by the action of the actuator 32, and processes the sheet material present between the upper gripping means 28 and the lower gripping means 30. The lower gripping means 30 is moved forward toward the machine 6 by a predetermined amount (the amount of movement of the upper gripping means 28 when it moves forward becomes the amount of advance of the sheet material), and the lower gripping means 30 is positioned in a non-operating position by the action of the actuator 32. When this occurs, it becomes inactive and does not effectively act on the sheet material existing between the upper gripping means 28 and the lower gripping means 30, stopping its movement. The upper gripping means 28 of the intermittent feeding means 4 is attached to the processing machine 6 as described later.
It moves back and forth in synchronization with the movement of.

A processing machine 6 disposed downstream of the intermittent feeding means 4
In the specific example, it consists of a press having a stationary lower part 34 containing the forming tool and a movable upper part 36 containing the forming tool. Stationary lower part 34 and movable upper part 36
A processing area is defined between and 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 highest position shown by a solid line in FIG. 1 and the lowest position shown by a two-dot chain line in FIG. is reciprocated. To explain further, when the movable upper part 36 is located below various fixed positions, that is, during processing, the forming tool of the movable upper part 36 and the forming tool of the stationary lower part 34 act on the sheet material existing in the processing area. Add press forming (processing machine 6 is in 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 non-processing period of the processing machine 6 will be explained with reference to FIG. 2 together with FIG. 1. FIG. 2 schematically shows the rotational movement of a crank 38 provided in an elevating mechanism for elevating and lowering the movable upper portion 36 of the processing machine 6. As shown in FIG. The crank 38 is rotated at a constant speed in the direction indicated 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. 1st
It is located at the lowest value indicated by the double-dotted chain in the figure. For example, while the crank 38 rotates from the angular position indicated by symbol C through the bottom dead center B to the angular position indicated by symbol D, the forming tool of the movable upper part 36 and the forming tool of the stationary lower part 34 are in the machining area. Press forming is applied to the sheet material existing in the crank 3
During the rotation of 8 from the angular position indicated by D through the top dead center A to the angular position indicated by C, the forming tool of the movable upper part 36 is separated from the sheet material present in the processing area. That is, while the crank 38 rotates from the angular position indicated by symbol C through the bottom dead center B to the angular position indicated by symbol D, the processing machine 6 is in the machining period (that is, the processing machine 6 is in the machining state). ), the crank 38 moves from the angular position indicated by the symbol D to the top dead center A
The processing machine is in a non-processing period during the rotation to the angular position indicated by symbol C (i.e., the processing machine 6
are in unprocessed condition). The processing machine 6 having such a configuration is
It can be selectively brought into an active state and a non-active state.
That is, the processing machine 6 enters the operating state when the drive source 39 is activated, and repeats the processing period and the non-processing period by the rotation of the crank 38 described above, and press-forms the sheet material existing in the processing area. alms,
On the other hand, when the drive source 39 stops, it becomes inactive,
The vertical movement of the movable upper part 36 is stopped, and the press forming of the sheet material is stopped.

In a specific example, the drive source 39 of the processing machine 6 (FIG. 3)
The upper gripping means 28 of the intermittent feeding means 4
is configured to reciprocate as described above, and the intermittent feeding means 4 advances the sheet material by a predetermined amount in synchronization with the vertical movement of the movable upper part 36 of the processing machine 6. To explain further, with reference to FIGS. 1 and 2, for example, the crank 38 is at an angular position indicated by symbol E (i.e., an angular position rotated by 270 degrees from top dead center A).
from top dead center A to the angular position indicated by symbol F (i.e., the angular position rotated 90 degrees from top dead center A)
While rotating over an angular range of 180 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 F to the bottom dead center B.
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 symbol E to the position indicated by symbol F (during this period, the processing machine 6 is in the non-processing period),
The intermittent feed means 4 advances the sheet material toward the processing area of the processing machine 6, while the crank 38 rotates from the angular position indicated by F to the angular position indicated by E (during which time the processing machine 6 is in a non-operational state). immediately before the end of the processing period, immediately after the processing period and the start of the processing period)
Then, the intermittent feeding means 4 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 constituted by 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, but the drive source 39 of the processing machine 6 is A dedicated drive source is separately provided, and the upper gripping means 2 moves in synchronization with the vertical movement of the movable upper part 36 of the processing machine 6 by the action of the drive source.
8 may be made to reciprocate as desired.

The illustrated sheet material conveying and processing system further includes:
The guide table 42 and the first cutting means 44 are arranged in relation to the conveying means 10 of the sheet material supply mechanism 2, and the second cutting means 44 is arranged in relation to the processing machine 6.
A cutting means 46 is provided. 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 at 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 48, as will be described later. That is, actuator 48
When the guide table 42 is deenergized, the guide table 42 is in a first position, shown in solid lines in FIG. , on the other hand, when the actuator 48 is energized, the guide table 42 is pivoted counterclockwise in FIG. A guide portion 42a defined on the lower surface guides the trailing end of the sheet material from the conveying means 10 toward the first cutting means 44, as will be described later.

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 3
It is rotated in a predetermined direction by the action shown in Figure). 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 actuated, and by the cooperative operation of a stationary shear blade and a rotating shear blade (neither of which are shown), the first cutting means 44 cuts the sheet material into smaller pieces as described below. When the drive source 50 is stopped, the rotating shear blade stops rotating and stops cutting the sheet material.

A pair of guide plates 52 and 54 are disposed upstream of the first cutting means 44.
Further, on the upstream side of 4, there are a pair of conveyor rows 56 and 5.
8 are arranged. In the specific example, one of the pair of conveyance rollers 56 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 sealing material toward the first cutting means 44, the sheet material is transferred to the guide present at the tip of the guide table 42. It is guided by the section 42a and 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 of substantially the same construction as the first cutting means 44 and is operated by a stationary shear blade (not shown) and a cutting drive source 60 (FIG. 3), such as an electric motor. It has a rotating shearing blade (not shown) that is rotated in a predetermined direction. This second cutting means 46 also includes, as will be described later,
It can be selectively brought into an active state and a non-active state.
That is, the second cutting means 46 becomes active when the drive source 60 is activated, and cuts the processed sheet material into small pieces by the cooperative action of the stationary shearing blade and the rotating shearing blade, as will be described later. When the drive source 60 is stopped, it becomes inactive and the rotary shear blade stops rotating and ceases 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 example sheet material conveying and processing system, the following detection means is 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. On the downstream side of the conveying means 10 and immediately upstream of the intermittent feeding means 4, there is a third
A sheet material detection means 70 is provided. On the downstream side of the guide table 42 and immediately upstream of the conveyance means 10, a fourth sheet material detection means 72 for detecting sheet material is arranged. Also,
A fifth sheet material detection means 74 for detecting sheet material is provided upstream of the first cutting means 44 and downstream of the conveyance rollers 56 and 58. Further, on the downstream side of the sheet material supply means 8 and on the upstream side of the conveyance means 10, at a portion where a desired loop is generated in the sheet material, there is provided a loop detection means 76 for detecting the loop state of the sheet material. is installed. 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-insufficiency detector 80 detects a first loop under-insufficient state, which will be described later. A second under-insufficient detector 82 detects a second loop under-situation, which will be described later. A third under-detector 84 is included. Immediately downstream of this loop detection means 76 is a loop abnormality detection means 86 for detecting an abnormality in the loop state of the sheet material.
is installed. These detection means (detector 7
8, 80, 82 and 86) 66, 68, 7
0, 72, 74, 76 and 86 are optical detectors which are known per se and have a light receiving element which receives the reflected light emitted from the light emitting element and reflected by the sheet material. The sheet material conveying and processing system described above is further arranged in association with the crank 38, as shown in FIGS. 2 and 3,
An angular position detecting means 88 is provided for detecting a specific angular position of the crank 38 (in the specific example, the angular position indicated by symbol E). 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 operations of various operating components such as the processing machine 6 based on output signals from the various detection means described above. 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 operating procedure of the above-described sheet material conveying and processing system will be described with reference to FIG. 4, which is a time chart showing the operating procedure of the sheet material conveying and 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 a 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 paper plane in FIG. 1 by the action of a moving drive source 96 such as an electric motor. It is configured as follows. In connection with this, each sheet material storage section 16 is equipped with a sheet material supply means 8, and the sheet material storage section 16 in which the sheet material to be supplied is stored.
A position detecting means 98 is provided for detecting when the is in a desired position.

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

() First, the start switch 100 (FIG. 3) of the sheet material conveying and processing system is manually closed. The entire system is then put into operation, and first, the control means 90 energizes the drive 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.

() 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. Thus, the position detection means 9
The control means 90 deenergizes the drive source 96 and energizes the drive source 18 based on the output signal from the drive source 8 . 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
becomes active, and the roller pair 12a and 12b
is rotated in a predetermined direction. In the specific example, the drive source 18 is rotated at a relatively high speed at this time, and the sheet material supply means 8 is in the third operating state.
Thus, the front end side of the sheet material 17 supported by the sheet material storage section 16 is connected to the roller pair 12.
a and 12b, and the conveying means 1 is carried out while being guided by a guide member (not shown).
It is sent towards 0.

() When the sheet material is fed as described above and the leading edge thereof is conveyed to the third sheet material detection means 70, the third sheet material detection means 7
0 detects this and generates an output signal. 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 activated;
Upper roller 20 is positioned in the active position, and upper roller 20 and lower roller 22 nip the leading edge of the sheet material between them. In this way, the sheet material is moved by the forward rotation of the drive source 24 to the upper gripping means 28 and the lower gripping means 3 of the intermittent feeding means 4.
0 and through the processing area that exists between the stationary lower part 34 and the movable upper part 36 of the processing machine. Further, at this time, since the loop detection means 76 is activated, the control means 90 controls the sheet material supply means 8 based on the signal from the loop detection means 76. The control of the sheet material supply means 8 using the signal from the loop detection means 76 will be described later. Accordingly, 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 active state (first working state, second working state, or third working state) and a non-working 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.

() When the sheet material is thus fed and its leading edge 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 first
An output signal from the sheet material detection means 66 causes the control means 90 to de-energize the actuator 26 and the drive source 24, and at the same time disable the actuator 32 and the drive source 39.
and 60 (at this time, the loop detection means 76 remains activated). 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. And the movable upper part 3
The upper gripping means 28 of the intermittent feeding means 4 is also reciprocated as desired in synchronization with the vertical movement of the intermittent feeding means 6. 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. Further, when the drive source 60 is energized, the second cutting means 46 is activated and a rotating shear blade (not shown) is rotated. Thus, the leading end of the sheet material is advanced by a predetermined amount toward the processing area of the processing machine 6 each time the upper gripping means 28 of the intermittent feeding means 4 advances, in other words, every time the processing machine 6 is not processing. The sheet material fed to the processing area by the action of the intermittent feeding means 4 is press-formed at each processing time of the processing machine 6, and the unnecessary parts of the sheet material after being processed in the processing area are , is cut into small pieces by the action of the first cutting means 46.

During the above-described processing by the processing machine 6, the loop detection means 76 is maintained in a differential state, and therefore, in connection with the advance of the sheet material by the intermittent feeding means 4, the control means 90 is controlled by the loop detection means 76. Based on the signal, the operation of the sheet material supplying means 8 is controlled as follows. To explain further, 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 small (a first loop small state).
Then, the first under-detector 80 detects the sheet material and generates an output signal. Thus, based on the output signal from the first under-supply detector 80, the control means 90 causes the drive source 18 to rotate at a relatively low speed, thereby causing the roller pair 12a and 12b of the sheet material supply means 4 to rotate at a relatively low speed. It is rotated at a low speed (the sheet material supply means 4 is in the first operating state) and the sheet material in the sheet material storage 16 is thus delivered at a relatively low speed. The first mentioned above
Despite the conveyance of the sheet material by the action of the sheet material feeding means 4 in the operating state, the loop state of the sheet material becomes even smaller than the first loop insufficient state (the second loop insufficient state occurs). ) and a second underdetector 82 detects the sheet material and generates a 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. The pair of rollers 12a and 12b of the sheet material supply means 4 are thus rotated at medium speed (the sheet material supply means 4 is in the second operating state), and thus the sheet material storage section 16
of sheet material is delivered at medium speed. Further, the sheet material supply means 4 in the second operating state
Despite the conveyance of the sheet material due to the action of
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 8 roller pair 12a and 12b to rotate at a relatively high speed. (sheet material supply means 4 is rotated by the third
), 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 feed means 4, the sheet material is When the sheet material is unloaded and its loop condition becomes excessive (over-loop condition), over-loop detector 78 detects the sheet material and generates an output signal. In this way, the control means 90 de-energizes the drive source 18 based on the output signal from the excess detector 78, thereby stopping the rotation of the pair of rollers 12a and 12b of the sheet material supply means 8 (the sheet material supply means 8 become inactive). As described above, during the processing period 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 advance 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 10, the loop detection means 76 is also activated in relation to the advance of the sheet material by the conveyance means 10. 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.

() The processing of the sheet material described above is carried out,
When 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. Thus, the second sheet material detection means 6
Based on the disappearance of the output signal of 8, the control means 90 first
The first timer means 92 operates, and the first timer means 92 generates an output signal after a predetermined time _t1 has elapsed after the start of the operation. Thus, the first timer means 9
Based on the output signal from 2, the control means 90 deenergizes the drive sources 18 and 39 and the actuator 32, and further deactivates the loop detection means 76,
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 pair of rollers 12a 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. Also,
When the drive source 39 and the actuator 32 are deenergized, the movable upper part 3 of the processing machine 6 is moved by the deenergization of the drive source 39.
6 is stopped, and the intermittent feeding means 4
The reciprocating movement of the upper gripping means 28 is stopped and the lower gripping means 30 of the intermittent feeding means 4 is positioned in the non-operating position by deenergizing the actuator 32, thus allowing the processing machine 6 and the intermittent feeding means 4 becomes inactive and processing of the sheet material is stopped. In a specific example, the above-mentioned deenergization of the drive source 39 is as follows:
Rotational motion of crank 38 (Figure 2) and processing machine 6
is carried out in relation to the machining speed in the operating state. To explain further, the storage means 94 of the control means 90 stores time T corresponding to various machining speeds.
is stored in advance. 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. and,
The position where the processing machine 6 is brought into a non-operating state means that if the drive source 39 is brought into a non-working state in such a position, the movable upper part 36 will not act on the sheet material present in the processing area when the processing machine 6 is stopped. The machining state is preferably set at a position where the movable upper part 36 is located near the uppermost position shown by a solid line in FIG. 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 inertial force of the movable upper part 36. Drive source 39
The position where is deenergized is closer to the angular position indicated by symbol E. On the other hand, when the processing speed of the processing machine 6 is relatively low, this is due to the relatively small inertia force of the movable upper part 36. The position where the time T becomes relatively long and the drive source 39 is deenergized is marked A.
Move to the top dead center side shown by . In the embodiment thus constructed, the second sheet material detection means 68 detects the trailing edge of the sheet material in the manner described above, and the angular position detection means 88 detects the angular position of the crank 38 indicated by the symbol E. When detected, the control means 90 reads the time T corresponding to the acceleration in the operating state of the processing machine 6 from the storage means 94 based on the output signals from the second sheet material detection means 68 and the angular position detection means 88,
After the read time T has elapsed (that is, the crank 38 moves from the angular position indicated by the symbol E to the arrow 4).
0), 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.

Meanwhile, at the same time, the drive source 24 and the actuator 2
When 6 is energized, the conveying means 10 is activated and the upper roller 20 and lower roller 22 nip the leading edge of the sheet material between them, as described above. Thus, the sheet material is further advanced by normal rotation of the drive source 24. At this time,
The drive source 60 continues to be energized, so that the sheet material fed by the action of the conveying means 10 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, and the sheet material storage section 16 from which all the sheet materials have been carried out is moved from the predetermined position, and new sheet materials are supported. The sheet material storage section 16 is moved toward a predetermined position.

() The support stand 95 is moved as described above,
When the sheet material storage section 16 supporting a new sheet material is moved to the position detecting means 98, the position detecting means 98 detects this and generates an output signal again. Then, the control means 90 deenergizes the drive source 96 again based on the output signal from the position detection means 98. 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. Material storage section 16
is positioned at the working position.

() Next, when the sheet material is fed by the action of the conveying means 10 and the rear end is conveyed to the fourth sheet material detecting means 72, the fourth sheet material detecting means 72 detects this. Loss the output signal. Thus, on the basis of the disappearance of the output signal of the fourth sheet material detection means 72, the control means 90 de-energizes the drive source 60 and at the same time causes the drive source 24 to reverse in the active state of the conveying means 10 (therefore, the actuator 26 continues to be energized) and energizes the actuator 48. Drive source 60
When is deenergized, the rotating shear blade (not shown) stops rotating and the second cutting means 46 becomes inactive. At the same time, when the drive source 24 is reversed while the conveying means 10 is in operation, 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 forced to move forward is transferred to the conveying means 1.
0, and this sheet member is guided from the rear end side by the guide portion 42a of the guide table 42 while passing through a pair of conveyor rollers 56 and 58.
, and is further moved toward conveyor rollers 56 and 5.
8 toward the first cutting means 44 (in the specific example, the conveyance roller 56 of the pair of conveyance rollers is drivingly connected to the drive source 24; is reversed, the transport rollers 56 are rotated to move the sheet material towards the first cutting means 44).

() 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. to 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, guide table 42 is pivoted clockwise in FIG. 1 to a first position shown in solid lines in FIG. The guide table 42 is nipped between the conveyor rollers 56 and 58 of the first
Even if the sheet material is positioned in the first position, the action of transport rollers 56 and 58 ensures that the sheet material
(toward the cutting means 44). on the other hand,
At the same time, when the drive source 50 is energized, the first cutting means 44 is activated and its pivoting shear blade (not shown) is pivoted. Thus, the unnecessary portion of the sheet material fed by the action of the conveying means 10 and the conveying rollers 56 and 58 is
It is cut into small pieces by the action of the cutting means 44.

() When 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 conveyed to the fifth sheet material detection means 74, the fifth sheet material The 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 the actuator 26 and the drive source 24 are deenergized, the upper roller 20 is positioned in a non-active position and the drive source 24 is stopped, and the conveying means 10
is again rendered inactive. 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 new sheet material is supported comes into operation, and the sheet material supply means 8 is activated in the same manner as described above. A new sheet material is conveyed towards the conveying means 10. 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 operates for a predetermined time t ₂ after the start of operation.
Generates an output signal after the elapsed time. This predetermined time t ₂
is the time required for the sheet material to fall under its own weight and be cut as required by the first cutting means 44. Thus, the second timer means 93
The control means 90 controls the drive source 50 based on the output signal of
emasculate. When the drive source 50 is de-energized, the rotating shear blade (not shown) stops rotating and the first cutting means 44 becomes inactive.

() 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. Thus, the third
The control means 90 again activates the actuator 26 and the drive source 2 by the output signal from the sheet material detection means 70.
4 is energized and the loop detection means 76 is 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, when the loop state becomes abnormally small while the sheet material is advancing (therefore, the loop becomes even smaller than the third loop small state), the loop abnormality detection means 86 detects the sheet material. The system is configured to detect this and generate an abnormal signal, and the entire system becomes inactive based on the abnormal signal.

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

Mainly referring to FIG. 5, the illustrated sheet material supply mechanism 2 includes a support base 102, on which a support base 95 is movably mounted. In the specific example, rails 104a and 104b are provided on the support base 102 at intervals in the vertical direction (horizontal direction in FIGS. 5 to 7), and support rollers 1 are provided on the lower surface of the four corners of the support base 94.

The rail 104a is received in the recess of 6b, while the other set of support rollers 106c and 106d are composed of cylindrical rollers, and the support rollers 106C and 1
06d is placed on the upper surface of the rail 104b. Therefore, these supporting rollers 106a, 106b,
106c and 106d are rails 104a and 1

As understood from FIG. 5, the pair of main support rollers 112 and the pair of auxiliary support rollers 114 rotatably support the belt-shaped sheet material 17 wound into a cylindrical shape, and the diameters of the sheet material 17 are compared. When the target is large, the main support rollers 112 and the auxiliary support rollers 114 act on the sheet material 17, and when the diameter of the sheet material 17 is relatively small, only the main support rollers 112 act on the sheet material 17. Each of the sheet material storage portions 16 described above includes:
A supply unit 14 is attached to which the sheet material supply means 8 having the above structure is attached. 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.

2b and further passes between the rollers 122b and 122c to the roller pair 12a of the sheet material supply means 8.
and 12b, during which the sheet material is decurled as required. In the specific example, since the upper side plate 118 is pivotable relative to the lower side plate 116, the rollers 122a and 122b in the curl removal means 120 can be removed by operating the release lever 124 (FIGS. 6 and 7). , the nip state of the rollers 122b and 122c, and the nip state of the rollers 12a and 12b in the sheet material supply means 8 can be released. This supply unit 14
is further provided with a pair of guide plates 126 and 128 extending downstream. One of the rollers 12a of the sheet material supply means 8 described above is drivingly connected to a drive source 18 provided at the bottom of the corresponding container 108 via a transmission means 130 such as a chain. In a specific example, as described above, the drive source 18 is composed of a variable electric motor,
During operation, it is rotated at a relatively low speed, a medium speed, or a relatively high speed based on a signal from the loop detection means 76.

A support structure 132 is disposed approximately in the middle of the support base 102 in the lateral direction. The illustrated support structure 132 includes a plurality of vertical members 134 and horizontal members 1
36, which are interconnected as required. This support structure 132 has
A relatively highly curved outer guide member 138 and a relatively lightly curved inner guide member 140 are mounted. In the specific example, the outer guide member 138
One end side is fixed to the vertical member 134, and the other end side is fixed to the horizontal member 136 and is attached to a protruding member 142 that protrudes upwardly so as to be adjustable in the vertical direction. Further, one end of the inner guide member 140 is fixed to one end of the horizontal member 136, and the other end is attached to the other end of the horizontal member 136 so as to be adjustable in the vertical direction. 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 the specific example, as understood from FIGS. 5 to 7, the support base 95 on which the sheet material storage section 16 is provided is attached to the support structure 1.

An operating shaft 14 is located in the longitudinally intermediate portion of the support base 102.
3 is arranged, and one end side of the operating shaft 143 is rotatably supported by a support member 144. The operating 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. Further, a transmission member 148 such as a sprocket is attached to one end of the operating shaft 143, and the transmission member 146 is drivingly connected to the output side of the drive source 96 via a transmission means 150 such as a chain. As shown above, when the drive source 96 is activated,
The operating shaft 142 is rotated, thus supporting the support base 95,

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. Furthermore, 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.

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. the first under-loop detector 80 detects this and the curved portion of the sheet material moves away from the outer guide member 138.
When it moves further away from the inner surface of the loop (the second loop under-representation mode is reached), the second under-reduction detector 82 detects this,
In addition, the curved portion of the sheet material is connected to the inner guide member 140.

Further, an abnormality detecting means 86 is disposed at the curved portion of the inner guide member 140. This abnormality detection means 86 detects that the curved portion of the sheet material is located inside the inner guide member 14.
This is detected when it comes into contact with the inner surface of 0. 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 detects the corresponding sheet material storage section 16.
Detects the detected member 156 provided in the. 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 1 are provided at both lateral ends of the support base 95 corresponding to the movement stop switches 158 and 160.
62 (only one of which is shown in FIG. 5) is provided. The other movement stop switch 158 detects one of the protruding pieces 160 and stops the drive source 96 when the support base 95 moves to the position shown by the two-dot chain line in FIG. 7 (only a portion is shown). Further, the other movement stop switch 160 has the support base 95 in the sixth position.
When the drive source 9 detects the other protruding piece 162 when moving to the position shown in the figure and the solid line in FIG.
6 is stopped. Accordingly, the support platform 95 is normally moved from the position shown in FIG. 6 and shown in solid lines in FIG. 7 through the support structure 132 to the position shown in two-dot chain lines in FIG. In addition, in a specific example,
In order to prevent the support stand 95 from coming off the rails 104a and 104b, one of the rails 104a
Stop pieces 164 and 166 are provided at both ends (FIG. 7). Furthermore, the guide plate 128 attached to the supply unit 14 is provided with material confirmation means 168 for detecting sheet material. To load the sheet material into the sheet material storage section 16 as desired, the sheet material is first loaded onto the main support rollers 112.

For example, in a specific example, the loop detection means 7
6 consists of an over-detector 78, a first under-detector 80, a second under-detector 82 and a third under-detector 84, but instead of this, the loop detecting means 76 is configured to detect over-detection It can also be composed of a detector 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 made inactive), and the undersized detector is When the device detects sheet material, the drive source 18 may be activated (the sheet material supply means 8 may be brought into operation). In addition, the loop detection means 76 includes an overdetector, a first underdetector, and a second underdetector.
When the first underdetection detector detects the sheet material, the drive source 18 is stopped (the sheet material supply means 8 is rendered inactive), and the first underdetection detector detects the sheet material. is detected, the drive source 18 is rotated at a relatively low speed (the sheet material supply means 8 is brought into the first operating state), and when the second underdetection detector detects sheet material, the drive source 18 is rotated at a relatively low speed. What is necessary is to rotate it at a high speed (to bring the sheet material supply means 8 into the second operating state).
