The present invention relates to a cutting device for cutting a sealing portion of a continuous small sealing body having an accommodating portion and a sealing portion alternately.

37 is a perspective view showing the continuous small bag 1.

The continuous small sealing member 1 has a band shape having alternating accommodating portions 2 and sealing portions 3, and each accommodating portion 2 contains sauces, soups, and the like of cup noodles.

In addition, the continuous small sealing member 1 seals a band-like sheet folded in two with the sealing portion 3 at predetermined intervals to form a plurality of receiving portions 2 having a bottom portion 2a, and these receiving portions 2 After accommodating the seasoning, soup, etc.), the opening of each accommodating part 2 is sealed by the closed sealing part 5, and is comprised.

In order to separate the continuous small encapsulation 1 into a plurality of small encapsulations, as shown in Fig. 41 (a), the sealing portion 3 is detected while conveying the continuous small encapsulation member 1 in the direction of an arrow A. The sealing portion 3 is supplied to the cutting means 4 on the basis of the detection signal to cut the sealing portion 3 between the lower blade 4a and the upper blade 4b of the cutting means 4.

Conventionally, in supplying the sealing part 3 of the continuous small sealing body 1 to the cutting means 4, the structure of (1) and (2) described below is employ | adopted.

In addition, the structure as described in (1) is disclosed by Unexamined-Japanese-Patent No. 6-10105.

Moreover, the structure as described in (2) is disclosed by Unexamined-Japanese-Patent No. 58-8647.

(1) The continuous small bag 1 is sandwiched by a pair of rollers, and the continuous small bag 1 is conveyed with the rotation of the roller.

(2) The conveying plate is attached to the piston rod of the air cylinder, and the conveying plate is engaged with the step between the accommodating part 2 and the sealing part 3 with the protrusion of the piston rod, and the continuous sealing member 1 is carried out by the conveying plate. Press to move it.

However, in the configuration of (1) and (2), the rollers and air cylinders are arranged on the opposite side of the arrow A of the cutting means 4, and the continuous bag 1 is extruded in the direction of the arrow A to cut. It supplied to the means 4.

For this reason, when extruding especially the soft continuous small sealing body 1, the continuous small sealing body 1 may bend, and the actual conveyance amount may shift with respect to a set amount.

Thus, when the conveyance amount shifted, there exists a possibility that the accommodating part 2 of the continuous small sealing body 1 may be cut | disconnected incorrectly.

In addition, the continuous small bag 1 is stored in a state of being folded in a meander shape and superimposed or wound in a roll shape.

For this reason, when the continuous small sealing body 1 is extruded after cutting the sealing part 3, as shown in Fig. 41 (b), the sealing part 3 which has a rounded curved shape at the time of storage is cut off. It was not possible to convey the continuous small sealing body 1 smoothly by interfering with the lower blade 4a (or upper blade 4b).

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to prevent the continuous small bag from bending at the time of conveyance, and furthermore, to ensure that the continuous small bag is surely supplied to the cutting means without being affected by the bending shape during storage. It is an object of the present invention to provide a cutting device for a continuous small bag.

And a conveying means for holding the cutting end portion and a conveying means for pulling the continuous small encapsulation body by the holding means and feeding the new sealing portion to the cutting means with moving the holding means in a direction away from the cutting means. It features.

According to the above means, when the cutting means cuts the sealing portion of the continuous small encapsulation member, the holding means first grips the cutting end portion from the carrying-out side of the cutting means.

Next, as the conveying means moves the holding means in a direction away from the cutting means, the continuous small encapsulation body is pulled to supply a new seal to the cutting means.

For this reason, unlike the conventionally carried out by pushing out a continuous small bag, a continuous small bag does not bend so that it may be conveyed.

In addition, since the cutting end portion with the bending habit can be grasped and pulled, the cutting end portion is smoothly conveyed without interfering with the cutting means.

The cutting device of the continuous small sealing body according to claim 2 is provided with a sealing means in the vicinity of the cutting means, which has a sealing part at the time of cutting and which releases the fitting of the sealing part after cutting.

According to the above means, since the means to be fitted at the time of cutting have the sealing portion, the continuous small sealing body can be reliably cut without rising.

In particular, when the contents are light or thin, the continuous small encapsulation may rise with the bending habit of the seal, but in this case, the continuous small encapsulation can be reliably cut from the encapsulation because the bending habit can be suppressed and corrected.

At the same time, since the means to be fitted after cutting releases the sealing portion, the continuous small sealing body is tensioned by the conveying means without any trouble.

The cutting device for a continuous small encapsulation member according to claim 30 is characterized in that the holding means releases the gripping portion of the sealing portion after the holding means grasps the cutting end of the continuous small encapsulation member.

According to the above means, since the gripping means grasps the cutting end portion in a state where the cutting end portion of the continuous small encapsulation body is fixed by the fitting means, the cutting end portion is reliably gripped without being influenced by the bending habit.

The cutting device of the continuous small-sealing body according to claim 4, wherein when the seal is cut, the gripping means moves relative to the cutting means while retaining the seal, thereby separating the cutting means from the end of the seal, and then inserting the seal. It is characteristic to release.

According to the above means, when the seal is cut, the fitting means moves relative to the cutting means, and a gap is formed between the cutting means and the cutting end of the seal.

For this reason, since the holding means can hold the cutting | disconnection end part of a sealing part through space | interval, interference of a holding means and a cutting means is prevented.

The cutting device of the continuous small sealing body according to claim 5 is characterized in that a cutting portion is formed to hold the cutting end portion of the sealing portion by means of the holding means inclined on the fitting means.

According to the said means, since the cutting edge part of a sealing part is gripped by the means which the holding means fits, the holding amount of the sealing part by a holding means increases.

In particular, when the holding means grips the cutting end portion in a state where the cutting end portion of the continuous small encapsulation body is fixed, it becomes easy to hold the cutting end portion.

This chuck 47e corresponds to the holding means and has a comb-tooth shape as shown in FIG.

As shown in FIG. 14, a tension coil spring 47f is attached between the chuck 47e and the chuck head 47, and the chuck 47e is in a solid line by the force of the spring of the tension coil spring 47f. As shown, it is maintained in the closed state (gripping the continuous small sealing body).

As shown in FIG. 15 and FIG. 16, a plurality of cutting | disconnection part 32d is formed in the clamp 32b.

As shown in FIG. 11, when the drive shaft 45 slides the maximum amount (maximum conveying position) in the opposite direction to the arrow A, the chuck 47e of the chuck head 47 is located between the cut portions 32d of the clamp 32. It is supposed to go in.

16 shows the portion of the clamp 32b from the side opposite to the arrow A. FIG.

A lever 49 is connected to the spline shaft 42 as shown in FIG. 13, and a lever 50 (see FIG. 3) is rotatably connected to the lever 49 as shown in FIG. 5. It is.

And the contactor 50a is provided in the lever 50, and when the contactor 50a moves along the cam surface of the cam 29f, the lever 50 will rotate.

As a result, the lever 49 moves up and down, and the spline shaft 42 in FIG. 9 rotates in the forward direction.

Lever 51 and 52 are rotatably attached to the chuck head 47 as shown in FIG.

And when the spline shaft 42 rotates, the rotational movement force of the spline shaft 42 is transmitted from the lever 51 to 52, and the lever 52 is made to rotate.

Here, when the lever 52 rotates as indicated by the two-point chain in FIG. 12 and presses the chuck 47e, the force of the spring of the tension coil spring 47f is indicated by the two-point chain in FIG. The chuck 47e rotates against it, and the chuck head 47 is in an open state (a state in which the grip of the continuous small sealing body is released).

Moreover, when the lever 52 rotates as shown by the solid line in FIG. 12, the pressing force on the chuck 47e is removed, and as shown by the solid line in FIG. 14, the chuck is driven by the force of the spring of the tension coil spring 47f. 47e is in the closed state.

The cutting end of the sealing portion 3 is gripped by the opening and closing of the chuck 47e while the drive shaft 45 slides in the opposite direction to the arrow A and the chuck 47e enters the clamp 32b.

If the drive shaft 45 slides in the direction of the arrow A (return direction) after the chuck 47e grips the cutting end of the sealing portion 3, the continuous small encapsulation member 1 held by the chuck 47e is arrowed. It is conveyed to (A) direction, and the accommodating part 2 and the sealing part 3 are alternately supplied to the suction head 13 and 14.

As a result, the seam detection signal is output from the seam detection circuit 25.

As shown in FIG. 9, the release head 53 is attached to the drive shaft 45 so that a movement is possible.

The release shaft 54 is fixed to the release head 53, and the release shaft 54 is inserted into the support head 44.

A predetermined friction force is applied between the drive shaft 45 and the release head 53 and between the release shaft 54 and the support head 44.

For this reason, in the state in which the restraint force is not acting on the release shaft 54, the release shaft 54 slides integrally with the drive shaft 45. As shown in FIG.

As shown in FIG. 17, an electronic switch 55 made of an electromagnetic solenoid is fixed to the base 26. As shown in FIG.

This electronic switch 55 is connected to the output terminal of the seam detection circuit 25 via the drive circuit 55a as shown in FIG. 25. When the seam detection signal is output from the seam detection circuit 25, the drive circuit is connected. The electronic switch 55 is energized via 55a, and as shown in FIG. 18 to FIG. 18, the plunger 55b of the electronic switch 55 is applied to the force of the spring of the compression coil spring 55d. It is intended to enter in the direction of the arrow A against.

In addition, when the electronic switch 55 is disconnected, the plunger 55b protrudes in the opposite direction to the arrow A by the force of the spring of the compression coil spring 55d.

The lever 56 is rotatably attached to the base 26 via the shaft 56a.

A compression coil spring 55c is fitted to the plunger 55b of the electronic switch 55, and the tip of the lever 56 is connected to the compression coil spring 55c.

And the pin 56b is provided in the lever 56, and the restraining member 26a is provided in the base 26, and as shown in FIG. 18, when the plunger 55b enters the arrow A direction, the lever 56 will be provided. It rotates about the shaft 56a, and the space | interval of the pin 56b and the restraining member 26a is narrowed.

As a result, the release shaft 54 is in compression contact with the restraining member 26a and the pin 56b and the slide of the release shaft 54 is restrained.

As shown in FIG. 9, the release head 53 is provided with the protrusion release part 53a.

When the slide of the release shaft 54 is constrained with the output of the seam detection signal, the chuck head 47 slides in the direction of the arrow A integrally with the drive shaft 45, and as shown in FIG. The release part 53a of the release head 53 enters into the accommodating part 47a of 47.

Then, since the release part 53a presses and moves the pin 47b of the chuck head 47 in the direction opposite to the arrow A, the pin 47b is formed on the inner surface of the receiving part 47a and the external source of the drive shaft 45. It is separated from the main surface, the connection between the drive shaft 45 and the chuck head 47 is released, and the conveyance operation | movement of the continuous small sealing body 1 is stopped.

In addition, the movement amount of the drive shaft 45 is set larger than the conveyance amount of the continuous small sealing body 1.

Therefore, the drive shaft 45 slides in the direction of the arrow A even after the slides of the release shaft 54 and the chuck head 47 are restrained.

19 shows the arrangement of the suction heads 13 and 14, the lower blade 31a and the upper blade 31b.

Where a is the distance between the upper blade 31b (lower blade 31a) and the suction heads 14 and 13, and b is the boundary between the receiving portion 2 and the sealing portion 3 (adsorption pad 13c and ( 14c) and the center part of the sealing part 3 (cutting position by the lower blade 31a and the upper blade 31b), and as shown in FIG. 11, the front end part of the release part 53a is shown. An interval of the width dimension a + b is formed between the pin 47b and the chuck head 47.

Therefore, as shown in FIG. 19, as the boundary between the receiving portion 2 and the unsealed portion 3 is supplied to the suction heads 13 and 14, a seam detection signal is output and the electronic switch 55 is operated. After the release shaft 54 is constrained, the drive shaft 45 and the chuck head 47 slide by the distance a + b in the direction of the arrow A, as shown in FIG. The release part 53a presses the pin 47b of the chuck head 47 and the connection between the drive shaft 45 and the chuck head 47 is released.

Thereby, conveyance of the continuous small sealing body 1 is stopped, and the center part of the sealing part 3 is supplied to the lower blade 31a and the upper blade 31b.

The drive circuit 55a of the electronic switch 55 has the maximum amount of the drive shaft 45 in the direction of the arrow A, reaches the maximum transport position, and then starts to move in the opposite direction to the arrow A. It is configured to power off.

Then, as shown in FIG. 18 to FIG. 17, the plunger 55b protrudes in the opposite direction to the arrow A by the spring coil force of the compressed coil spring 55d, and the lever 56 moves the shaft 56a. Rotate to the center

Thereby, the space | interval of the restraining member 26a of the base 26 and the pin 56b is expanded, and the restraint of the release shaft 54 by the pin 56b is cancelled | released.

The return head 46 is attached with a return rod 46a extending in the opposite direction to the arrow A. As shown in FIG.

If the drive shaft 45 slides in the opposite direction to the arrow A while the restraint of the release shaft 54 is released, the drive shaft 45, the chuck head 47, and the release head 53 are released from the state shown in FIG. With the slight sliding between the return rod 46a and the chuck head 47, the return head 46, the chuck head 47, the release head 53, and the release shaft 54 are in contact with each other. It slides integrally in the direction opposite to the arrow A.

The carrying amount adjusting member 57 is attached to the support head 41.

The conveying amount adjusting member 57 has an operation portion 57a and a stopper portion 57b. When the drive shaft 45 and the release shaft 54 slide in the opposite directions to the arrow A, the release shaft 54 stops. The movement of the release shaft 54 abuts against the part 57a.

As a result, the drive shaft 45 slides in the direction opposite to the arrow A with respect to the release shaft 54, and as shown in FIG. 11, the release head 53 is removed from the receiving portion 47a of the chuck head 47. The release part 53a is peeled off.

Then, the pin 47b of the chuck head 47 protrudes in the direction of the arrow A by the force of the spring of the compression coil spring 47c and compresses the inner surface of the receiving portion 47a and the outer circumferential surface of the drive shaft 45. Since it is in contact with the inner surface of the accommodating portion 47a and the outer circumferential surface of the drive shaft 45, the pin 47b of the chuck head 47 has a distance a + b from the distal end of the release portion 53a. Apart and the chuck 47a enters the clamp 32b.

In addition, in order to adjust the moving distance a + b of the chuck head 47, the operation amount 57a of the conveyance amount adjustment member 57 may be rotated, and the amount of protrusion of the stopper portion 57b may be adjusted.

The length dimension of the return rod 46a is set longer than the separation distance a + b between the chuck head 47 and the release head 53.

The timing sensor 58 is attached to the base 26 as shown in FIG.

The timing sensor 58 is disposed close to the cam surface of the cam 29a shown in FIG. 5 and is irrelevant to the conveyance operation in the direction of the arrow A of the drive shaft 45 (convex portion of the cam surface of the cam 29a). Is detected and a detection signal is output.

The timing sensor 58 is connected to the drive circuit 55a of the electronic switch 55 and the drive circuit 55a drives the electronic switch 55 while receiving the detection signal from the timing sensor 58. Prohibit.

FIG. 26 is a time difference art of a series of small bag insertion operations, and the operation of the above-described configuration will mainly be described with reference to FIG.

Cam 29a in conjunction with operation of electric motor 27 When 29j rotates, the upper blade 31b, the clamps 32b, and 35 descend.

When the phase angle of the electric motor 27 reaches 10 °, the clamps 32b and 35 move to the bottom dead center, and the clamp 35 is engaged with the pin 32c of the mounting plate 32a.

At the same time, the clamp 32b also sandwiches the sealing portion 3 of the continuous small sealing member 1 between the mounting plate 32a.

Then, when the phase angle reaches 20 °, the chuck 47e moves from the closed state to the open state, and when the phase angle reaches 30 °, the push rod 39 descends from the top dead center.

When the phase angle reaches 40 °, the sealing portion 3 of the continuous encapsulation member 1, in which the upper blade 31b moves to the lower point and is sandwiched between the mounting plate 32a and the clamp 32b, is the upper blade 31b. And the lower edge 31a are cut off and the chuck 47e is opened when the phase angle reaches 55 °.

In addition, the upper edge 31b moves to the bottom dead center at a phase angle of 40 °, then starts to rise at a phase angle of 45 ° and reaches a top dead center at a phase angle of 100 °.

When the phase angle reaches 60 °, the push rod 39 moves to the bottom dead center, and the small bag separated from the continuous small bag 1 is stabbed out and put into the lower container.

At the same time, the front end of the mounting plate 32a is inclined while the clamps 32b and 35 start to rise and the cutting end of the seal 3 is sandwiched between the clamp 32b and the mounting plate 32a. Therefore, a space | interval is formed between the cutting edge part of the sealing part 3 and the lower blade 31a, and between the cutting edge part of the sealing part 3, and the upper blade 31b.

In addition, the push rod 39 starts rising at a phase angle of 65 ° after reaching the bottom dead center and reaches a top dead center at a phase angle of 105 °.

Incidentally, the raising operation of the clamps 32b and 35 is once stopped at a phase angle of 80 degrees.

When the phase angle reaches 60 °, the drive shaft 45 at the maximum return position (the position where the return head 46 is closest to the support head 43) starts to slide in the opposite direction to the arrow A (the conveyance direction). do.

Then, since the driving circuit 55a disconnects the electronic switch 55, the restraint of the release shaft 54 is released and the release head 53 is brought into contact with the chuck head 47 by the return rod 46a of the return head 46. ), The release shaft 54 and the chuck head 47 move in the opposite direction to the arrow A. FIG.

And since the release shaft 54 contacts the stopper part 57b of the conveyance adjustment member 57, since the release shaft 54 is restrict | limited and the drive shaft 45 slides with respect to the release shaft 54, The release portion 53a of the release head 53 is peeled off from the receiving portion 47a of the chuck head 47.

As a result, the chuck head 47 is connected to the drive shaft 45.

Thereafter, when the phase angle reaches 130 °, the drive shaft 45 moves to the maximum conveying position, and the pin 47b of the chuck head 47 is separated from the distal end of the release part 53a by a distance a + b.

Moreover, when the phase angle reaches 130 degrees and the drive shaft 45 moves to the maximum conveyance position, the chuck head 47 is positioned on the conveyance shaft of the continuous sealing member 1 in the lower blade 31a to seal the portion 3. The chuck 47e of the chuck head 47 is clamped through the gap between the cutting end of the cutting edge and the lower blade 31a and the distance between the cutting end of the sealing portion 3 and the upper blade 31b. ) Into the cutout portion 32d and protrude toward the opposite side of the arrow A of the clamp 32b.

At the same time, the chuck 47e goes from the open state to the closed state.

Thereafter, when the phase angle reaches 155 °, the clamps 32b and 35 which have been stopped once start rising, and the engagement between the clamp 35 and the pin 32c of the mounting plate 32a is released.

Then, the mounting plate 32a is rotated by its own weight and the mounting plate 32a is separated from the clamp 32b, so that the insertion of the continuous sealing member 1 by the clamp 32b is released.

At the same time, just before the insertion of the continuous small encapsulation member 1 is released, the chuck 47e is brought into a closed state and the cutting edge of the continuous small encapsulation member 1 is gripped.

In addition, the clamps 32b and 35 start to rise at a phase angle of 155 ° and reach a top dead center at a phase angle of 170 °.

When the phase angle reaches 170 °, the drive shaft 45 starts to slide in the direction of the arrow A (return direction).

Then, the chuck head 47, the releasing head 53, and the releasing shaft 54 move integrally with the driving shaft 45, so that the continuous small bag 1 held by the chuck 47e of the chuck head 47 is arrowed. It is conveyed in the direction (A).

When the continuous small encapsulation member 1 is conveyed in the direction of the arrow A, and the sealing portion 3 of the continuous small encapsulation member 1 is supplied to the adsorption pads 13c and 14c, Adsorption of at least one side and the continuous small sealing member 1 is released, and at least one of the negative pressures in the intake passages 19 and 20 changes to the positive pressure side.

Then, since at least one of the pressure switches 21 and 22 is turned on, the seal detection signal is output from the seam detection circuit 25.

When the seal detection signal is output from the seal detection circuit 25, the electronic switch 55 is energized via the driving circuit 55a, and the plunger 55b of the solenoid 55 enters the arrow A direction.

Then, with the rotation of the lever 56, the pin 56b of the lever 56 comes into compression contact with the release shaft 54, so that the slide of the release shaft 54 is constrained and the drive shaft 45 continues to release the release head ( 53) and the release shaft 54 in the direction of the arrow (A).

When the drive shaft 45 slides about the release head 53 and the release shaft 54, the release portion 53a of the release head 53 intrudes into the receiving portion 47a of the chuck head 47 and the chuck head 47. The pin 47b of) is pressurized in the direction opposite to the arrow (A).

Then, since the pin 47b is separated from the outer circumferential surface of the drive shaft 45 and the inner surface of the receiving portion 47a, the engagement between the chuck head 47 and the drive shaft 45 is released and the chuck head 47 is moved. Stop.

Thereby, the conveyance operation | movement of the continuous small sealing body 1 is stopped, and the sealing part 3 is supplied between the lower blade 31a and the upper blade 31b.

In addition, the stationary conveyance amount in FIG. 26 corresponds to the movement amount a + b of the chuck head 47.

Then, when the phase angle reaches 340 °, the clamps 32b and 35 fall from the top dead center.

When the phase angle reaches 360 °, the drive shaft 45 is moved to the maximum return position, and the above-described series of operations are repeated after one cycle is completed.

In addition, when the drive shaft 45 moves to the maximum return position to synchronize the belt conveyor at the lower side of the push rod 39 with the lowering operation of the push rod 39 to ensure the small bag is put in the container, the motor 27 It is supposed to be energized again after the power is cut off.

According to the embodiment described above, the chuck 47e is provided on the arrow A direction side of the lower blade 31a and the upper blade 31a, and the chuck 47e is moved in the direction of the arrow A by the chuck head 47. By moving, the continuous small sealing body 1 was pulled and the new sealing part 3 was supplied to the lower blade 31a and the upper blade 31b.

For this reason, since the cutting edge part of the sealing part 3 with a bending habit can be gripped and tensioned, the cutting edge part of the sealing part 3 is prevented from interfering with the lower blade 31a and the upper blade 31b.

In addition, since the continuous small encapsulation 1 is prevented from being bent at the time of conveyance, the continuous small encapsulation 1 is collectively conveyed as set so that the sealing portion 3 is securely secured to the lower edge 31a and the upper edge 31b. Can supply

Moreover, in cutting the sealing part 3, the sealing part 3 was made to fit by the mounting plate 32a and the clamp 32b.

Because of this, it is surely cut without the occurrence of (3).

In particular, when the contents are light or thin, the continuous small encapsulation member 1 rises due to the bending habit of the sealing portion 3, and thus the position of the continuous small encapsulation member 1 may be displaced. It may shift | deviate from the sealing part 3.

In the present embodiment, on the other hand, the sealing portion 3 is fitted by the mounting plate 32a and the clamp 32b.

For this reason, since the bending habit can be suppressed and correct | amended, the continuous small sealing body 1 is reliably cut | disconnected from the sealing part 3.

In addition, the sealing part 3 was cut | disconnected and the sealing part 3 was opened with the mounting plate 32a and the clamp 32b in cutting the sealing part 3 and conveying the continuous small sealing body 1.

For this reason, the continuous small bag 1 can be conveyed without interruption.

Moreover, the chuck | zipper 47e grasped the cutting | disconnection end part of the sealing part 3 in the state which fixed the cutting | disconnection end part of the sealing part 3 between the mounting plate 32a and the clamp 32b.

For this reason, since the cutting edge part of the sealing part 3 is gripped firmly without being influenced by a bending habit, the conveyance of the continuous small sealing body 1 is performed reliably.

In addition, between the lower blade 31a and the cutting edge of the sealing portion 3, the upper blade 31b and the cutting edge of the sealing portion 3 are moved along with moving the mounting plate 32a and the clamp 32b. Formed gaps in between.

For this reason, the chuck 47e does not interfere with the lower blade 31a and the upper blade 31b because the chuck 47e can hold the cutting end of the sealing portion 3 through this interval.

In addition, the chuck 47e is configured to hold the cutting edge of the sealing portion 3 via the clamp 32b.

For this reason, since the holding amount of the cutting edge part by the chuck 47e becomes large, it can prevent that the continuous small sealing body 1 escapes from the chuck 47e by the movement of the chuck 47e.

In addition, even when the cutting edge part of the sealing part 3 of the continuous small sealing body 1 is gripped, the cutting edge part can be reliably gripped.

In addition, since the comb-shaped chuck 47e is used, even if oil or the like adheres to the surface of the continuous small bag 1, the continuous small bag 1 can be reliably tensioned without slipping.

By the way, in detecting the sealing part 3 of the continuous small sealing body 1, the structure shown to (1) and (2) described below was used conventionally.

(1) The continuous small encapsulation body 1 is sandwiched by a pair of movable rollers, and the sealing portion 3 is detected from the amount of movement of the roller along the thickness direction of the continuous small encapsulation member 1.

(2) The label printed on the sealing part 3 is read by a photoelectric sensor.

However, in the case where the step between the housing portion 2 and the sealing portion 3 is unclear, in the apparatus of (1), the amount of movement of the roller is extremely small and the sealing portion 3 cannot be accurately determined.

In addition, in the case of the apparatus of (1), contents, such as condiments, can be pressed and broken.

In addition, in the apparatus of (2), the trouble of printing the front cover in advance is necessary.

Along with this, there is a fear that letters or the like printed on the continuous bag 1 are not discriminated from the front cover, or there is no difference in color between the front cover and the continuous bag 1. The label may not be detected.

On the other hand, in the above embodiment, the sealing portion is based on the determination of the adsorption state of the continuous sealing member 1 by the suction pads 13c and 14c based on the output signals from the pressure switches 21 and 22. (3) was detected.

For this reason, unlike the structure of (2), the trouble of printing a front cover previously is abolished.

Along with this, there are no unreasonable points such as the characters printed on the continuous small bag 1 being misidentified as a cover, or there is no difference in color between the front cover and the continuous small bag 1, and thus no cover is detected.

Moreover, unlike the structure of (1), even if the step difference between the accommodating part 2 and the sealing part 3 is not clear, the sealing part 3 can be discriminated correctly.

Along with this, the absurdity caused by the contents such as seasonings being pressed and broken is eliminated, and the sealing portion 3 is reliably detected as a whole.

In addition, by using the vacuum generator 17 and the intake passage 19, the adsorption force is applied to the qxj continuous small bag 1 by the adsorption pad 13c, and the adsorption is performed using the vibration generator 18 and the intake passage 20. Adsorption force was exerted on the continuous small bag 1 from the pad 14c.

For this reason, since the intake passages 19 and 20 become independent paths, the responsiveness of the pressure switches 21 and 22 is good, and as a result, the seam detection operation is speeded up.

In addition, the adsorption heads 13 and 14 were installed so as to be movable upward and downward, and a force was applied in the direction approached by the tension coil spring 15.

For this reason, the suction pads 13c and 14c pressurize the suction pads 13c and 14c against the force of the spring of the tension coil spring 15 so that the suction pads 13c and 14c are the continuous packing members ( In order to follow the shape of 1) and move up and down, the sealing part is detected stably without a mistake.

In addition, the suction heads 13 and 14 were suspended by the tension coil springs 16 and held.

For this reason, even if the conveyance position of the continuous condenser 1 is shifted up and down due to an error of a conveying mechanism or the conveyance position of the continuous encapsulation 1 moves up and down during conveyance, the tension coil spring 16 stretches and absorbs the vertical movement. For this reason, the sealing part 3 is stably detected also without a mistake.

In addition, the stoppers 24a and 24b restrict the access of the suction pads 13c and 14c, and in the access restricted state, the gaps larger than the thickness dimension of the sealing portion 3 are separated by the suction pads 13c and (b). 14c).

For this reason, when the sealing part 3 is supplied to the suction pads 13c and 14c, at least one of the suction pads 13c and 14c will be reliably separated from the continuous small sealing member 1, so that the sealing part ( 3) is stably detected without error.

In addition, the anti-curling protrusions 13e and 14e of the suction heads 13 and 14 guide the continuous small bag 1 to the suction surface of the suction pad 13c and the suction surface of the suction pad 14c. did.

For this reason, as shown in FIG. 39, since the continuous small sealing body 1 can prevent the adsorption pad 13c and 14c from rolling up, the sealing part 3 is stably detected erroneously even in this case. .

In addition, the opening and closing of the suction pads 13c and 14c were restricted by bringing the suction pads 13c and 14c into contact with the enlarged opening preventing wall portions 13g and 14g.

Therefore, as shown in FIG. 38, since the amount of adsorption by one of the adsorption pads 13c and 14c becomes excessive and the other side can be prevented from being greatly separated from the continuous small bag 1, the sealing is also advantageous. The part 3 is stably detected without error.

However, in controlling the conveyance amount of the continuous small sealing body 1 and supplying the sealing part 3 to the lower blade 31a and the upper blade 31b, conventionally, the conveying roller for conveying the continuous small sealing body 1 is pulsed. The transmitter is connected, and the pulse generator is driven in accordance with the rotation of the conveying roller to detect the conveyance amount of the continuous small encapsulation body 1, and the detection signal of the sealing part 3 is conveyed at the point when a constant pulse is output from the pulse generator. Stopping the electric motor is performed.

In this apparatus, however, the apparatus becomes expensive because a microcomputer or a sequencer controller which controls the electric motor based on the output signal from the pulse generator in addition to the movement measuring means called the pulse generator is required.

On the other hand, in the embodiment described above, the taper-shaped accommodating portion 47a, the compression coil spring 47c, and the pin 47b are disconnected from the drive shaft 45 and the chuck head 47 by mechanical means such as the continuous sealing member ( The conveyance amount of 1) was controlled.

This eliminates the need for expensive electrical means, such as movement measurement means and controllers, resulting in cost savings for the device.

Further, based on the output of the seam detection signal from the seam detection circuit 25, the distance "(a + b)" (dimension + accommodation portion extending from the cutting means 31 to the boundary between the receiving portion 2 and the sealing portion 3) 2) the chuck head 47 is moved by the boundary from the boundary of the seal part 3 to the center part of the seal part 3), and then the connection between the chuck head 47 and the drive shaft 45 is released and the continuous rod is removed. The conveyance operation of the delay member 1 was stopped.

For this reason, even if there is a nonuniformity in the length dimension along the arrow A direction of the accommodating part 2, the cutting position of the sealing part 3 (the distance (b) from the boundary between the accommodating part 2 and the sealing part 3). Can be surely supplied to the lower blade 31a and the upper blade 31b.

In addition, since the conveyance stop timing of the continuous small sealing body 1 is determined from the movement amount of the chuck head 47, it is sealed without being affected by the nonuniformity of the conveying speed of the continuous small sealing body 1 by the rotational nonuniformity of the electric motor 27, etc. The center part of the part 3 can be reliably supplied to the lower blade 31a and the upper blade 31b.

In addition, since the initial position (feed amount a + b) of the chuck head 47 can be adjusted by the conveying amount adjusting member 57, for example, the type of the continuous sealing member 1 is changed to accommodate the receiving portion ( 2) and the case where the length dimension of the sealing part 3 changes or when there is a manufacturing error in an apparatus, the dimensional change or the error is correct | amended, and the center part of the sealing part 3 is lower blade 31a and upper blade 31b. Can be surely supplied.

In addition, since the amount of conveyance of the continuous encapsulation body 1 can be easily adjusted even during the operation of inserting the bag, there is no need to stop the work and adjust the amount of conveyance.

In addition, the chuck head 47 is brought into contact with the return rod 46a in sliding the drive shaft 45 in the direction opposite to the arrow A. FIG.

For this reason, since the return timing of the chuck head 47 is delayed, the chuck head 47 is prevented from interfering with the push rod 39, and it is prevented from disturbing the sticking of the small bag.

In addition, the joint detection means using the suction pads 13c and 14c and the pull-out conveying means using the chuck 47e were combined, so that the joint detection means, the lower blade 31a and the upper blade were combined. It is not necessary to provide a conveying means such as a roller between 31b.

For this reason, since the suction pads 13c and 14c can be arrange | positioned between the lower blade 31a and the upper blade 31b, a device becomes small.

According to the above embodiment, when the adsorption pads 13c and 14c adsorb the accommodating part 2, the accommodating part detection signal is output from the joint detection circuit 25.

The driving circuits 59a and 60a then excite the electromagnetic solenoids 50b and 60b.

Then, the crank mechanisms 59c and 60c operate, and as shown in FIG. 28, the suction pads 13c and 14c move away from the continuous small bag 1 while absorbing the continuous small bag 1. Go to location.

Therefore, the sealing part 3 is supplied to the adsorption pads 13c and 14c with the adsorption pads 13c and 14c separated from the continuous small sealing body 1.

For this reason, as shown in FIG. 40, the adsorption pad 13c and 14c are prevented from adsorb | sucking with the continuous small sealing body 1, and as shown in FIG. 28, the adsorption pad 13c and ( The suction of the continuous small sealing member 1 by 14c) is surely released.

When the adsorption of the continuous small sealing member 1 by the suction pads 13c and 14c is released, the seam detection signal is output from the seam detection circuit 25.

Then, the driving circuits 59a and 60a release the solenoids 50b and 60b, so that the crank mechanisms 59c and 60c operate and the suction pads are in the approaching position approaching the continuous bag 1. 13c and 14c move.

Therefore, since the next accommodating part 2 is surely adsorbed by the adsorption pads 13c and 14c, the sealing part 3 is detected stably without error as a whole.

In addition, in the second embodiment, the suction pads 13c and 14c are moved up and down by the moving means 59 and 60 with the solenoids 59b and 60b as the main subjects, but the present invention is limited thereto.

A pressure sensor which detects the pressure values in the intake passages 19 and 20 and outputs an analog signal may be provided.

In this case, it is enough to detect that the negative pressure in the intake passages 19 and 20 changes to the positive pressure side by comparing the output signal from each pressure sensor with the reference value.

Next, a third embodiment of the present invention will be described with reference to FIG.

In addition, the same code | symbol is attached | subjected about the same member as 1st Example, description is abbreviate | omitted, and only another member is demonstrated next.

The vacuum generator 17 has a smaller suction force than the vacuum generator 18, and the suction force by the suction pad 13c on the lower side is smaller than the suction force by the suction pad 14c on the upper side.

Therefore, the continuous small bag 1 is conveyed while being always adsorbed by the suction pad 14c.

In addition, the pressure switch 22 corresponding to the intake passage 20 is closed, and the joint detection circuit 61 discriminates the sealing portion 3 based on the output signal from the pressure switch 21.

According to the above embodiment, when the receiving portion 2 of the continuous small sealing body 1 is supplied to the suction pads 13c and 14c, the suction pad 13c sucks the receiving portion 2.

As a result, the negative pressure in the intake passage 19 becomes large and the pressure switch 21 is turned off, so that the accommodating part detection signal is output from the joint detection circuit 61.

When the sealing portion 3 of the continuous small sealing member 1 is supplied to the suction pads 13c and 14c, the suction of the lower suction pad 13c and the continuous small sealing member 1 is released.

Then, since the negative pressure in the intake passage 19 changes to the positive pressure side, and the pressure switch 21 is turned on, the seal detection signal is output from the joint detection circuit 61.

Therefore, since the pressure switch 22 is closed and the circuit structure of the joint detection circuit 61 is simplified, cost reduction of the apparatus is achieved.

In the third embodiment described above, in order to make the suction force of the suction pad 13c less than the suction force of the suction pad 14c, the vacuum generators 17 and 18 having different suction forces are used, but the present invention is limited thereto.

It may be larger than the ventilation resistance of the intake passage 20.

In particular, in the case where the adsorption areas of the adsorption pads 13c and 14c are different from each other, when the adsorption force of the adsorption pads 13c and 14c is made to act through a common intake passage from one vacuum generator, It becomes lower price.

In the third embodiment, the adsorption force of the adsorption pad 13c is less than that of the adsorption pad 14c. However, the adsorption force of the adsorption pad 14c is less than that of the adsorption pad 13c. do.

In addition, in the above-described third embodiment, the pressure switch 21 is turned on / off in accordance with the pressure level in the intake passage 19. However, the present invention is not limited thereto. For example, the pressure value in the intake passage 19 is detected and analogized. A pressure sensor that outputs a signal may be provided.

In this case, it is good to detect that the negative pressure in the intake passage 19 changes to the positive pressure side by comparing the output signal from the pressure sensor with the reference value.

In the third embodiment described above, the configuration in which the adsorption forces of the suction pads 13c and 14c differ from each other is applied to the first embodiment, but is not limited thereto. For example, the second embodiment may be applied to the second embodiment.

The intake pipes 63b and 63c are connected to the intake pipe 63a, and when the vacuum generator 62 is operated, air in the suction pad 13c passes through the intake pipe 63b from the intake pipe 63a. The air in the suction pad 14c is sucked through the suction pipe 63c from the suction pipe 63a.

The pressure switch 64 is inserted into the intake pipe 63a.

The pressure switch 64 is turned off when the negative pressure in the intake pipe 63a becomes large, and is turned on when the negative pressure in the intake pipe 63a changes to the positive pressure side. The pressure switch 64 is connected to the joint detecting circuit 65.

According to the embodiment described above, when the receiving portion 2 of the continuous small sealing member 1 is supplied to the suction pads 13c and 14c, the suction pads 13c and 14c suck the receiving portion 2.

Then, since the negative pressure in the intake pipe 63a becomes large, the pressure switch 64 turns off and the accommodating part detection signal is output from the joint detection circuit 65. FIG.

When the sealing part 3 is supplied to the suction pads 13c and 14c, the suction by at least one of the suction pads 13c and 14c is released.

Then, since the negative pressure in the intake pipe 63a changes to the positive pressure side, the pressure switch 64 is turned ON, and the seam detection signal is output from the seam detection circuit 65.

Therefore, since the pressure switch 64 can cope and the circuit configuration of the joint detection circuit 65 is simplified, the cost reduction of the apparatus is achieved.

In addition, in the fourth embodiment, the adsorption pads 13c and 14c are fixed to the adsorption heads 13 and 14, but not limited thereto. For example, as in the third embodiment, an electromagnetic solenoid or an electric motor is used.

In the pad accommodating part 14b of the suction head 13, the suction pad 14c is accommodated so that it can move up and down.

In addition, a compression coil spring 66 is interposed between the upper surface of the suction pad 14c and the upper wall of the pad receiving portion 14b. 1) I apply force to the side (bottom).

A ring-shaped stopper 67 is fixed in the pad accommodating portion 14b, and the suction pad 14c contacts the stopper 67 while approaching the continuous sealing member 1 (moved downward). It is positioned at the approach position.

In addition, as shown in parentheses in FIG. 31, the adsorption pad 13c is accommodated in the pad receiving portion 13b of the adsorption head 13 so as to be movable up and down, and the adsorption pad 13c is a compression coil spring 66 A force is applied to the continuous small bag 1 (upper side) and is positioned at an approaching position approaching (moving upward) the continuous small bag 1 while touching the stopper 67.

In the corners of the suction heads 14 and 13, chamfers 13h and 14h are formed.

The chamfers 13h and 14h are formed in place of the arc portions 14f and 13f, and the receiving portion 2 of the continuous small bag 1 is a corner portion of the suction heads 14 and 13. It guides to the adsorption surface of the adsorption pad 14c, and the adsorption surface of the adsorption pad 13c, without being caught.

According to the above embodiment, when the adsorption pads 13c and 14c adsorb the receiving portion 2, the negative pressure in the adsorption pads 13c and 14c becomes large.

The adsorption pads 13c and 14c then move against the force of the spring of the compressed coil spring 66 and move away from the continuous bag 1.

Therefore, since the sealing portion 3 is supplied to the suction pads 13c and 14c while the suction pads 13c and 14c are separated from the continuous small sealing member 1, the suction pads 13c and 14c are separated by the suction pads 13c and 14c. Adsorption is surely released.

When the suction by the suction pads 13c and 14c is released, the negative pressure in the suction pads 13c and 14c changes to the positive pressure side.

Then, the suction pads 13c and 14c protrude by the force of the spring of the compression coil spring 66 and approach the continuous small sealing member 1.

For this reason, since the next accommodating part 2 will be surely adsorb | sucked, the sealing part 3 will be detected steadily without a whole error.

Since the suction pads 13c and 14c move, the sealing portion 3 can be detected reliably and stably.

Furthermore, when the suction pads 13c and 14c are integrally formed on the suction pads 13c and 14c, the suction pads 13c and 14c are moved by separate compression coil springs 32. The parts score is reduced.

In the second embodiment, however, the air in the suction pad 13c is sucked by the vacuum generator 17 and the intake passage 19, and the air in the suction pad 14c is sucked by the vacuum generator 18 and the intake passage. Due to suction by (20), if a deviation occurs in the adsorption timing between the suction pads 13c and 14c, a deviation occurs in the increase timing of the negative pressure in the intake passages 19 and 20, respectively.
