Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous supply device capable of continuously supplying a belt-shaped sheet material having a finite length (supplying while performing automatic joining).

[0002]

2. Description of the Related Art A method for packaging tablets, capsules, etc. is a strip-shaped resin sheet material having a plurality of pack parts which are vertically and horizontally aligned and can be separated into individual parts, and each pack part is provided with each lock part. There is one that is housed and sealed with a back sheet material (aluminum foil, etc.) attached to a resin sheet material.

In the case of performing such packaging (manufacturing a packaging material), the resin sheet material and the back sheet material are wound in a roll state around a tubular core material which is long in a strip shape, respectively. Be prepared as what was done. Then, while feeding each of these strip-shaped sheet materials, after forming the pack portion and loading tablets etc. on the resin sheet material,
The packaging material is manufactured by sticking the two together.

By the way, the resin sheet material and the back sheet material have a finite length as a matter of course, and therefore, when one roll has been used, the residual core is removed, a new roll is loaded, and the preceding strips are formed. It is necessary to join the sheet material and the subsequent strip-shaped sheet material. Conventionally, all of these tasks have been done manually.

[0005]

Since the removal of the residual core, the loading of a new roll, and the joining of the leading side strip-shaped sheet material and the trailing side strip-shaped sheet material are manually performed, the work itself is required. , Was inefficient. Not only this, the feeding of the resin sheet material and the back sheet material must be stopped during these operations, which naturally lowers the manufacturing efficiency of the packaging material.

The present invention has been made in view of the above circumstances, and all the work relating to the replacement of old and new rolls is automatically performed.
By making it possible to perform it continuously, the work is simplified or reduced,
Another object of the present invention is to provide an apparatus for continuous supply of strip-shaped sheet material capable of improving work efficiency (production efficiency of products made of strip-shaped sheet material).

[0007]

In order to achieve the above object, the present invention takes the following technical means. That is, the present invention is a feeding operation unit for feeding a strip-shaped sheet material, a rear end holding unit for holding a rear end portion of the feeding strip-shaped sheet material, and a sheet loading unit for feeding the replenishment belt-shaped sheet material to the feeding operation unit. , A leading end guide portion for drawing out the feeding start end portion of the replenishing strip-shaped sheet material loaded in the feeding operation portion to the trailing end holding portion, and a trailing end portion and a leading end portion of the leading side belt-shaped sheet material held by the trailing end holding portion. A sheet connecting portion that connects the starting end portion of the trailing side strip-shaped sheet material held in the guide portion in a superposed manner, and adjusts the tension amount of the preceding side strip-shaped sheet material on the downstream side of the rear end holding portion and feeds it. It is characterized in that it is provided with a seat tension portion for holding the speed.

[0008]

In the process of feeding out the strip-shaped sheet material held in the feeding operation section, when the band-shaped sheet material becomes less or runs out and the trailing end portion is fed out, first, the rear end holding section Holds the rear end of the strip-shaped sheet material in a predetermined state. In this state, the feeding operation unit discharges the residual core of the strip-shaped sheet material.

Next, the sheet loading section sends the replenishing strip-shaped sheet material to the feeding operation section for loading. Then, the feeding start leading end of the strip-shaped sheet material after loading is pulled out to the trailing end holding portion by the leading end guiding portion. In the trailing edge holding portion, the trailing edge portion of the leading side belt-shaped sheet material that is already held and the leading edge portion of the trailing side belt-shaped sheet material pulled out by the leading edge guiding portion are placed in an overlapping state, and the sheet connection is performed. By the operation of the parts, the overlapping parts are integrally connected.

During these series of operations, the leading strip-shaped sheet material is gradually fed out by the tension amount (total withdrawal length) accumulated by the sheet tensioning portion provided on the downstream side of the trailing edge holding portion. The feeding speed on the downstream side is maintained constant.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an apparatus 1 for continuous supply of strip-shaped sheet material W according to the present invention. This apparatus 1 has a feeding operation unit 2, a rear end holding unit 3, a sheet loading unit 4, and a starting end. The guide portion 5, the seat connecting portion 6, and the seat tension portion 7 are provided.

The feeding operation unit 2 is rotationally driven so that the core material C can be pierced and held with respect to the strip-shaped sheet material W (see FIG. 4 made of resin) prepared in a roll state. It has a shaft 10. This rotary drive shaft 10
Can be rotated forward and backward by a rotating tool 11 such as an electric motor via a transmission means 12 (belt transmission in the drawing), and the strip-shaped sheet material W can be continuously or intermittently fed.

A holding means (shown in the figure) for holding the core material C of the strip-shaped sheet material W on the rotary drive shaft 10 in a non-idle state by an appropriate method such as clamping force in the axial direction or engagement or expansion in the radial direction. Is omitted). In the feeding operation unit 2, the rotary drive shaft 10 has a bearing 15 that holds the root of the rotary drive shaft 10 as shown in FIG. Is held by the advancing / retreating guide means 17 integrally with the rotary drive shaft 10 so as to be advancing / retreating along the axis thereof. Furthermore, this bearing 1
6 is driven back and forth by a forward and backward drive means 18. That is, the rotary drive shaft 10 can move in and out between two positions, a position for rotating the belt-shaped sheet material W (state shown in FIG. 2) and a position retracted from this position (left side in FIG. 2). ing.

In this way, when the rotary drive shaft 10 is advanced and retracted from its rotational position toward the retracted position,
The core material C (see FIG. 4) held by the rotary drive shaft 10 can be extracted and dropped. In this embodiment, the rotary drive shaft 10 and the bearing 15 have a spline shaft structure fitting relationship, a linear way is used as the advancing / retreating guide means 17, and an electric motor driven ball screw mechanism is used as the advancing / retreating drive means 18. Was used.

As shown in FIG. 1, the rear end holding portion 3 is a pinch roller body 20 in which a pair of rollers are in contact with each other.
Is provided. At least one of the rollers can be driven and rotated. The trailing edge holding portion 3 is configured to hold the trailing edge portion detached from the core material C in a pinched state by the pinch roller body 20 when the strip-shaped sheet material W fed by the feeding operation portion 2 is used up. .

Incidentally, the strip-shaped sheet material W usually has its winding start end adhered to the core material C, and if this adhered portion is forcibly peeled off from the core material C,
The adhesive, the adhesive tape, or the debris of the core material C remains attached to the band-shaped sheet material W, and cannot be used as the band-shaped sheet material W. In view of this, in this embodiment, a cutter device 21 that can cut an appropriate portion of the belt-shaped sheet material W is provided on the upstream side (lower side in FIG. 1) of the pinch roller body 20, that is, near the rotary drive shaft 10. . That is,
With respect to the pinch roller body 20, the rear end of the strip-shaped sheet material W generated by the operation of the cutter device 21 is clamped and held.

As will be described later, the rear end of the strip-shaped sheet material W is actually below the pinch roller body 20 by a predetermined length (120 mm further below the pinch roller body 50 of the feeding section 40 described later). Position) It is positioned so as to hang down, and therefore, as described above, the pinch roller body 2
The "rear end portion" to be held by 0 includes the position which is traced back from the hanging rear end by the above length.

As shown in FIG. 3, the cutter device 21 includes a cutting portion 26 which constitutes scissors by a fixed blade 24 and a movable blade 25, and a drive portion 28 which swings the movable blade 25 via a transmission means 27. have. In addition, an advancing / retreating mechanism 30 is attached to the cutter device 15, and the whole thereof is
It is possible to move forward and backward (in the vertical direction in FIG. 3) so that the strip-shaped sheet material W can move in and out of the feeding path.

In this embodiment, a fluid pressure (pneumatic) cylinder is used as the drive unit 28, a combination of a link 27a and a slider 27b is used as the transmission unit 27, and a guide unit and a fluid pressure (property) are appropriately used as the advancing / retreating mechanism 30. A combination of cylinders (pneumatic) was used. Therefore, the cutter device 21 initially stands by at the position (upper position in FIG. 3) that has withdrawn from the feeding path of the belt-shaped sheet material W, and the belt-shaped sheet material W loaded on the rotary drive shaft 10 is substantially fed. Is detected (when the remaining amount is almost exhausted), the strip-shaped sheet material W is advanced to the feeding path (lower position in FIG. 3), and the strip-shaped sheet material W is automatically cut (that is, strip-shaped). The sheet material W is separated from the core material C).

It is preferable that the rotation of the rotary drive shaft 10 and the feed operation of the pinch roller body 20 be stopped when the cutter device 21 is operated. The remaining amount of the strip-shaped sheet material W held on the rotary drive shaft 10 is detected by, for example, detecting that the roll radius of the strip-shaped sheet material W is reduced to a predetermined diameter by various detectors such as photoelectric sensors. In addition to the above, it can be performed by a method of converting the payout length from the rotation speed of the rotary drive shaft 10, a method of directly measuring the payout length, or the like.

In this embodiment, the method for detecting the roll radius of the strip-shaped sheet material W and the method for converting the rotation speed of the rotary drive shaft 10 are used together. The sheet loading section 4
As shown in FIGS. 1 and 2, in the front of the rotary drive shaft 10, a plurality of rolls (2
Approximately 5 rolls) A container portion 33 that can be received in a lined state, and an advancing / retreating guide means 34 that holds the container portion 33 so that the container portion 33 can advance / retreat along the axial direction of the rotary drive shaft 10.
And an advancing / retreating drive means 35 for advancing / retreating the container part 33.

Therefore, the sheet loading section 4 can successively deliver the replenishing strip-shaped sheet material W to the feeding operation section 2. In this embodiment, a linear way is used as the advance / retreat guide means 34, and the advance / retreat drive means 3 is used.
A ball screw mechanism driven by an AC servomotor was used as the No. 5. As shown in FIG. 1, the leading end guide portion 5 contacts the outer peripheral surface of a new strip-shaped sheet material W (the outer diameter of which is substantially constant) held by the rotary drive shaft 10 as necessary. The unwinding roller 38 that moves so that it can come into contact with or separate from it
Guide device 39 that opens and closes the feeding path of the sheet to either the open state or the predetermined gap state, and the pulling driving force for the belt-shaped sheet material W guided between the guide device 39 when the guide device 39 is closed (the predetermined gap state). Sending part 40 that conveys
Is provided.

Therefore, the starting end guide portion 5 exhibits the following actions with the predetermined forward and reverse rotation operations of the rotary drive shaft 10. That is, after the new belt-shaped sheet material W is held on the rotary drive shaft 10 (the feeding start end portion is oriented in the clockwise direction as shown in FIG. 5), first, the unwinding roller is placed on the outer peripheral surface thereof. 38 abuts. Next, the rotary drive shaft 10 once rotates the strip-shaped sheet material W in the counterclockwise direction (see arrow X). As a result, the feeding start end portion of the strip-shaped sheet material W reaches between the guide device 39 and the unwinding roller 38. In this state, the rotation drive shaft 10 switches the rotation direction to rotate in the clockwise direction (arrow Y). (See) to start rotation. At this time, the guide device 39 is in a state in which the feeding path of the strip-shaped sheet material W is closed (a state in which it is held in a predetermined gap), and the feeding start end portion of the strip-shaped sheet material W is guided through the inside of the guide device 39 and upward. To be done.

Then, after this, the feeding section 40 (see FIG. 1)
Is adapted to transmit the pulling drive to the belt-shaped sheet material W. By the way, the feeding section 40 (a pinch roller body 50 described later) includes a pinch roller body 2 of the rear end holding section 3 described above.
The trailing end portion of the leading-side strip-shaped sheet material W held by 0 is already in the holding state. Of course, the trailing end portion of the leading-side strip-shaped sheet material W does not interfere with the outer peripheral surface of the roll of the trailing-side strip-shaped sheet material W held by the rotary drive shaft 10 (120 mm below the pinch roller body 50 described later). It is supposed to hang down at the position).

Therefore, when the starting end of the trailing strip-shaped sheet material W reaches the feeding portion 40, the starting end and the trailing end of the preceding strip-shaped sheet material W are superposed. Becomes Therefore, in the feeding section 40, the pulling drive is transmitted to the rear end portion and the start end portion of both strip-shaped sheet materials W while keeping them in the overlapping state (see FIG. 6).

In order to bring the unwinding roller 38 into and out of contact with the strip-shaped sheet material W, the long side end of the swing lever 43 (43a is the swing center) assembled in the L-shape. A structure is adopted in which the unwinding roller 38 is held and the swinging drive is transmitted to the end portion on the short side. The swinging drive is performed by a telescopic drive tool 44 such as a fluid pressure (pneumatic) cylinder. That is, when the expansion / contraction drive tool 44 retracts, the swing lever 43 swings in the tilting direction as shown in FIG. 5, and the unwinding roller 38 comes into contact with the outer peripheral surface of the strip-shaped sheet material W. On the other hand, when the expansion / contraction driving tool 44 advances, the rocking lever 43 rocks in the upright direction as shown in FIG. 1, and the unwinding roller 38 separates from the belt-shaped sheet material W.

Further, the unwind roller 3 is attached to the swing lever 43.
A rotating tool 45, such as an AC servo motor, for rotating 8 is provided. The guide device 39 is arranged such that a pair of sandwiching plates 47, 48 having an integrated structure sandwiches the feeding path of the strip-shaped sheet material W, and is provided so as to be positionally adjustable in the left-right direction in the drawing. , 48
The respective inner surfaces facing each other are formed as smooth surfaces on which the strip-shaped sheet material W can be smoothly slid.

In the present embodiment, a guide bar structure is adopted as the means 49 for guiding the movement of the sandwiching plates 47, 48, and the movable source thereof is to engage with the swing end of the swing lever 43. The structure utilizing the swing of the swing lever 43 is adopted. Of course, it is also possible to provide a unique drive tool (fluid pressure cylinder, ball screw mechanism driven by an electric motor, solenoid, etc.) as the guide device 39.

Further, when the strip-shaped sheet material W approaches the end portion, the sandwiching plates 47 and 48 retreat in the direction perpendicular to the paper surface to release the strip-shaped sheet material W so that the cutter 21 can cut it (FIG. 5). reference). The feed unit 40 includes a pinch roller body 50 in which a pair of rollers are in contact with each other. At least one of the rollers can be driven and rotated.

By the way, when the rotary drive shaft 10 is rotated in the counterclockwise direction (X direction) in the starting end guide portion 5, the feeding start end portion of the belt-shaped sheet material W is guided by the guide device 39.
In this embodiment, the following method is used as a method for detecting that the gap between the roller and the unwinding roller 38 is reached. That is, as shown in FIG. 4, a mark M is applied to the strip-shaped sheet material W in a new roll state in advance with a magic pen or the like at the feeding start end portion. Then, the rotary drive shaft 10
A detector (not shown) such as a reflection type photoelectric sensor is provided around the periphery of the belt-shaped sheet material W.

Further, it is determined how far the detector is positioned in the circumferential direction from the position between the guide device 39 and the unwinding roller 38 by the rotation angle of the rotary drive shaft 10 (which can be measured by an encoder). Alternatively, it is measured in advance as the arrival time or the like according to the rotation speed. After doing so, the rotary drive shaft 10 is rotated counterclockwise (X direction in FIG. 5).
It is rotated to and waits for detection of the mark M by the detector. Then, after the detector detects the mark M, the rotation drive shaft 10 is rotated until it corresponds to the rotation angle or the arrival time, and is stopped at that time.

In this embodiment, in order to improve the positional accuracy which is correlated with the detection of the mark M and the rotation stop of the rotary drive shaft 10, the detector for the mark M is provided with the guide device 39 and the unwinding roller 38. In this method, the rotation driving shaft 10 is rotated one extra rotation after the mark M is detected by the detector. By doing so, the rotation drive shaft 10 can be stopped in anticipation of the rotational inertia.

The seat connecting portion 6 is the rear end holding portion 3
A thermocompression bonding device 53 is provided between the pinch roller 20 and the pinch roller 50 of the starting end guiding portion 5 so as to sandwich the feeding path of the belt-shaped sheet material W. The thermocompression bonding device 53 has a fixed heater 54 and a movable heater 55 facing each other, and the movable heater 55 is moved toward and away from the fixed heater 54 by an advancing / retreating drive tool 56.

Therefore, in the sheet connecting portion 6, as shown in FIG. 6, the trailing end portion of the leading-side strip-shaped sheet material W held by the trailing end holding portion 3 and the trailing end portion held by the leading end guiding portion 5 are provided. The starting end portion of the strip-shaped sheet material W on the side can be polymerized with each other and connected by heat welding. In this embodiment, a fluid pressure (pneumatic) cylinder is used as the advancing / retreating drive member 56. As the heater, it is possible to employ electromagnetic induction, ultrasonic waves, heat conduction (heating wire, etc.) or other heating methods. Further, when a material other than a resin material is used as the strip-shaped sheet material W, the heaters 54, 55 can be replaced with an adhesive applicator.

As shown in FIG. 1, the sheet tension portion 7 has a plurality of reversing pulleys 58 for guiding the strip-shaped sheet material W in a meandering shape on the downstream side (upper side in FIG. 1) of the rear end holding portion 3. Each of the reversing pulleys 58 is divided into a fixed row 59 side and a movable row 60.
The reverse pulley 58 of 0 is the reverse pulley 58 of the fixed row 59.
It is possible to approach and separate from.

Therefore, in the sheet tension portion 7, the total feeding length of the strip-shaped sheet material W can be stored in the form of meandering, and the stored amount can be lengthened or shortened. , Can be adjusted appropriately.
That is, for example, even when it is necessary to intermittently receive the strip-shaped sheet material W on the downstream side of the sheet tension portion 7, the movable row 60 is inverted while being synchronized with the intermittent (stop) timing. The pulley 58 is gradually separated from the reversing pulley 58 of the fixed row 59, and when the pulley 58 is received, the pulley 58 is brought closer to absorb the separated amount, so that the rotary drive shaft 1
The payout by 0 can be made continuously constant.

Particularly, it is possible to absorb the shocking tension generated at the time of intermittent receiving, does not extend to the belt-shaped sheet material W, and is not twisted or broken, and does not cause a device failure. There is. Further, the cutter device 21 (see FIG.
When the rotary drive shaft 10 needs to be stopped during the operation of (1), the removal of the residual core from the rotary drive shaft 10, the loading of a new belt-shaped sheet material W, the operation of the leading end guide portion 5 or the sheet connecting portion 6, and the like. Even in this case, the reversing pulley 58 of the movable row 60 is brought closer to the reversing pulley 58 of the fixed row 59 in the sheet tension portion 7, thereby supplying the strip-shaped sheet material W to the downstream side of the sheet tension portion 7. Can be maintained under constant conditions (intermittent feed or continuous feed).

When the rotation of the rotary drive shaft 10 is restarted (for example, after the connection of the strip-shaped sheet material W is completed), the reversing pulley 58 of the movable row 60 is replaced with the reversing pulley 5 of the fixed row 59.
8 is detected by a sensor or the like or measured by a potentiometer according to the amount of proximity to the movable row 60.
The reversing pulley 58 may be returned at once. In this embodiment, the reversing pulley 58 of the movable row 60 is provided on the moving frame 61, and the moving frame 61 is fixed by a pair of sliding driving tools 62 (guide bars) that both guide and drive the movement. Proximity to the reverse pulley 58 of row 59
I tried to separate them. Further, in order to maintain a constant tension with respect to the strip-shaped sheet material W, a tension adjusting spring 63 that resists the movement toward the proximity is attached to the moving frame 61 and is fed by the pinch roll 20.

The strip-shaped sheet material W sent out from the sheet tension section 7 is sent downstream (a step of forming a tablet storing cup section, etc.) through a twist direction changing roller 65 and a dance suppressing roller row 66. It In the supply continuation apparatus 1 of the present invention configured as described above, initially, a predetermined number of strip-shaped sheet materials W are placed on the sheet loading unit 4, and the rotary drive shaft 1
One roll of strip-shaped sheet material W is loaded into 0, and the feeding start end portion thereof reaches a predetermined position (start end guide portion 5 and rear end holding portion 3).
Through so as to extend to the downstream side of the sheet tension portion 7).

When the operation of starting the operation is performed, a predetermined feeding (intermittent feeding or continuous feeding) of the belt-shaped sheet material W by the rotary drive shaft 10 and the sheet tension portion 7 is automatically performed. When the belt-shaped sheet material W on the rotary drive shaft 10 is running low, the cutter device 21 of the rear end holding unit 3 is operated (see FIG. 3), the residual core is removed when the rotary drive shaft 10 is retracted, and the rotary drive shaft is removed. 10 advancing and loading the new strip-shaped sheet material W by the joint operation with the sheet loading section 4 (see FIG. 2), the rotation of the rotary drive shaft 10 and the withdrawal of the feeding start end section by the joint operation with the start end guiding section 5 (see FIG. 5). (Refer to FIG. 6), and the rear end portion of the leading side strip-shaped sheet material W and the start end portion of the trailing side strip-shaped sheet material W by the sheet connecting portion 6 (see FIG. 6) are performed substantially in this order.

That is, by these, the strip-shaped sheet material W
Is automatically spliced. Therefore, on the downstream side of the sheet stretching portion 7, the supply of the strip-shaped sheet material W is automatically continued under a certain condition (intermittent feeding or continuous feeding), and the strip-shaped sheet material to the sheet loading portion 4 is supplied. Little manual intervention is required, except to replenish W. By the way, the present invention
The invention is not limited to the above embodiment.

For example, although the air pressure is exemplified as the fluid pressure cylinder, hydraulic pressure, water pressure or the like may be used. Further, the portion exemplified as the ball screw mechanism can be used as a feed mechanism by chain transmission or rope transmission, or a fluid pressure cylinder. It is also possible to replace the portion exemplified as the electric motor with a fluid pressure motor or the like.

In addition to the above, various kinds of guide means to be used, shapes, materials, detailed configurations of respective members, or auxiliary mechanisms and instruments (cutter device 21, tension adjusting spring 63, twist direction changing roller 65, dance suppressing roller row). 66) and the like and the configuration thereof can be changed as appropriate. Further, in the present invention, the belt-shaped sheet material W is not limited to be made of resin, and can be used for metal stays, paper, cloth and the like.

Needless to say, the present invention is not limited to the case of producing a packaging material such as tablets and capsule tablets.
