The present invention relates to a conveying apparatus for a workpiece, which supplies the workpiece to the workpiece in performing a predetermined operation on the workpiece by the workpiece.

59 shows a continuous small bag 1 as an example of the workpiece. 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 the band-like sheet folded in two with the sealing portion 3 at predetermined intervals to form a plurality of receiving portions 2 having the bottom portion 2a, and these receiving portions 2 After accommodating spices, soups, and the like, the opening of each accommodating part 2 is sealed with a closed sealing part 5. In order to separate the continuous small encapsulation 1 into a plurality of small encapsulations, as shown in FIG. 63, the continuous small encapsulation 1 is conveyed in the direction of an arrow A, and the sealing portion 3 is detected by the seam detecting means. The cutting means 4 supplies the sealing portion 3 to the cutting means 4 having the lower blade 4a and the upper blade 4b based on the detection signal from the seam detecting means. I am trying to cut the center part.

Conventionally, the conveying apparatus of following (1) was used in controlling the conveyance amount of the continuous small sealing body 1, and supplying the sealing part 3 to the cutting means 4 which is a working apparatus. In addition, the following apparatus is disclosed by Japanese Unexamined-Japanese-Patent No. 62-38228 and Japanese Unexamined-Japanese-Patent No. 5-7258.

(1) The continuous small sealing body 1 is conveyed by the rotation of the conveyance roller. Then, the pulse generator is driven by the rotation of the conveying roller to detect the conveying amount of the continuous small bag 1, and the output signal of the seam detection signal from the seam detecting means is signaled at a time when a certain number of pulses from the pulse generator are output. Stop the motor of the transfer roller.

However, in the conventional apparatus described above, the apparatus is 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 quantity measuring means called the pulse generator is required. In this case, it is conceivable to use a relatively inexpensive member called a delay circuit and delay the stop signal output by using the detection signal from the seam detecting means as a signal for a predetermined time to give it to the motor.

However, in this configuration, if the rotational speed of the motor becomes uneven due to the load or the voltage change, even if the stop signal is delayed for a predetermined time and applied to the motor, the sealing portion is not supplied to the cutting means 4 as the work device. For this reason, since it is necessary to control the rotation amount of an electric motor using the measuring means or a controller mentioned above, cost reduction which was originally aimed at cannot be achieved.

In the configuration in which the motor of the conveying roller is stopped at a time when a predetermined number of pulses are output from the output of the seam detection signal or the delay signal is delayed for a predetermined time from the output of the seam detection signal, the arrow of the receiving portion 2 ( If a nonuniformity occurs in the length dimension along the A) direction, there is also an irrationality that the central portion (working position) of the sealing portion 3 cannot be reliably supplied to the cutting means.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a conveying device for a workpiece, which is capable of supplying the workpiece position to the apparatus with a cheap configuration without using measuring means or a controller. .

The conveying apparatus of the workpiece according to claim 1 includes a first moving means and a first moving means which move by a driving force of a driving source in supplying the workpiece to the workpiece in order to perform a predetermined operation on the workpiece by the workpiece. 2 moving means, conveying means for conveying the workpiece, connecting means for moving the conveying means together with the first moving means by connecting the first moving means to the conveying means, and a predetermined position of the workpiece A restraining end for restraining the movement of the second moving means based on the detecting means for detecting and the detection signal outputted from the detecting means, and a conveying means provided on the second moving means for moving the workpiece (a + b). (Where a is the distance between the detection position of the detection means and the working position of the work device, b: the distance between the detection position of the workpiece by the detection means and the work position of the workpiece by the work device. Distance) And a release means for releasing the connection between the first moving means and the conveying means by the connecting means, spaced apart in the direction of movement relative to the connecting means by the moving distance of the connecting means necessary for the movement, and the second restraining means being restrained. Characterized in that the disconnecting means is configured to actuate the connecting means as the connecting means moves at a distance of travel relative to the release means.

According to the above means, in a state where the predetermined position of the workpiece does not pass through the detecting means, the driving force of the driving source is transmitted from the first moving means to the conveying means via the connecting means, and the conveying means moves so that the workpiece is moved. Conveyed toward.

At the same time, the first moving means moves together with the first moving means and the conveying means.

Then, when the predetermined position of the workpiece passes through the detecting means, the restraining means is activated and the restraining force is applied from the restraining means to the second moving means.

Then, the connecting means moves by the distance "a + b" with respect to the release means, and the release means activates the connection means and releases the connection between the first moving means and the conveying means.

Because of this, the driving force of the drive source is not transmitted to the conveying means, so the conveying means is stopped and the work position of the workpiece is supplied to the work position.

Therefore, expensive electrical means such as movement measuring means and controller are unnecessary, so that the cost of the device can be reduced.

As shown in FIG. 5, the contacts 48b and 48c are attached to the lever 48, and the contacts 48b and 48c move along the cam surface of the cam 29b and the cam surface of the cam 29c. The lower surface lever 48 is rotated about the axis 48a.

Then, the rotational movement force of the lever 48 is transmitted from the support head 44 of FIG. 9 to the drive shaft 45, and the drive shaft 45 slides in the direction of the arrow A and the half arrow A.

As shown in FIG. 14, the chuck 47e is rotatably attached to the chuck head 47 via the shaft 47d.

A tension coil spring 47f is attached between the chuck 47e and the chuck head 47, and the chuck 47e is rotated as shown by a solid line by the force of the spring of the tension coil spring 47f. It is kept in a state of holding a continuous small bag.

In addition, the chuck 47e has a comb teeth shape 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 as shown 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).

In addition, when the lever 52 rotates as shown by the solid line in FIG. 12, the pressing force against the chuck 47e is removed, and as shown by the solid line in FIG. 14, by the force of the spring of the tension coil spring 47f. The chuck 47e is blocked.

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 direction of the half 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.

Then, a predetermined frictional 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.

Reference numeral 70A denotes a second moving means composed of the release head 53 and the release shaft 54.

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

The 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 ( The electric switch 55 is energized via 55a, and as shown in FIG. 18 to FIG. 18, the planar 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 arrow A against.

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

As shown in FIG. 17, the lever 56 is rotatably attached to the base 260 via the shaft 56a.

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

And the pin 56b is provided in the lever 56, and the restraint member 26a is provided in the base 26, and as shown in FIG. 18, when the planar 55b enters the arrow A direction, the lever 56 Is rotated about the shaft 56a and the gap between the pin 56b and the restraining member 26a is narrowed.

As a result, the release shaft 54 is pressed against the restraining member 26a and the pin 56b, and the slide of the release shaft 54 is restrained.

Reference numeral 70 denotes a restraining means composed of an electronic switch 55 and a lever 56.

As shown in Fig. 9, the release head 53 is provided with a projection-like release portion 53a corresponding to the release means.

Then, when the slide of the release shaft 54 is restrained based on the output of the seam detection signal from the joint detection circuit 25, the chuck head 47 integrally with the drive shaft 45 causes the arrow ( In the direction of A), as shown in FIG. 10, the release part 53a of the release head 53 enters into the accommodating part 47a of the chuck head 47. As shown in FIG.

Then, since the release part 53a pushes the pin 47b of the chuck head 47 in the direction of the half arrow A, the pin 47b is formed on the inner surface of the receiving portion 47a and the outer circumferential surface of the drive shaft 45. A state in which the drive shaft 45 is separated from the chuck head 47 is released, and the conveyance of the continuous small bag 1 is stopped.

In addition, the movement amount of the drive shaft 45 is set larger than the conveyance amount (assuming maximum conveyance amount) of the continuous small sealing body 1. As shown in FIG.

Therefore, the drive shaft 45 slides in the direction of the arrow A even after the slide of the chuck head 47 is stopped.

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

Here, a is the distance between the upper blade 31b (lower blade 31a) and the suction heads 14 and 13, that is, the distance from the detection position of the detection means to the working position of the working apparatus.

B is the distance between the boundary between the receiving portion 2 and the sealing portion 3 and the center of the sealing portion 3, that is, the distance from the position to be detected to the position to be worked, as shown in FIG. An interval of the width dimension a + b is formed between the distal end of the release portion 53a and the pin 47b of the chuck head 47.

In addition, the space | interval a is set shorter than the length dimension (pitch between mutually detected positions) of the accommodating part 2. As shown in FIG.

Therefore, as shown in FIG. 19, the seam detection signal from the seam detection circuit 25 is output as the boundary between the receiving portion 2 and the sealing portion 3 is supplied to the suction heads 13 and 14. As shown in FIG. 10, if the driving shaft 45 and the chuck head 47 slide in the direction of the arrow A by the moving distance a + b after the release shaft 54 is restrained. As described above, the release portion 53a of the release head 53 presses the pin 47b of the chuck head 47 and the connection between the drive shaft 45 and the chuck head 47 is released.

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

The driving circuit 55a of the electronic switch 55 has the electric drive 55 disconnected when the drive shaft 45 moves the maximum amount in the direction of arrow A to reach the maximum return position and starts to move in the direction of the half arrow A. Is configured to.

Then, as shown in FIG. 18 to FIG. 17, the planar 55b protrudes in the direction of the half arrow A by the force of the spring of the compressed coil spring 55d, and the lever 56 is the shaft 56a. Rotate around.

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

As shown in FIG. 10, a return rod 46a extending in the direction of the half arrow A is attached to the return head 46. As shown in FIG.

Then, when the drive shaft 45 slides in the direction of the half arrow A while the restraint of the release shaft 54 is released, the chuck head between the drive shaft 45 and the release head 53 starts from the state shown in FIG. With slight slip between 47 and the drive shaft 45, the return head 46, the chuck head 47, and the release head 53 are brought into contact with the return rod 46a and the chuck head 47. ), The release shaft 54 slides integrally in the half arrow A direction.

To the support head 41, a conveyance amount adjusting member 57 corresponding to the adjusting means is attached. 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 direction of the half arrow A, the release shaft 54 is the stopper portion. In contact with 57a, the movement of the release shaft 54 is restricted.

As a result, the drive shaft 45 slides in the direction of the half arrow A with respect to the release shaft 54, and the release head 53 is released from the receiving portion 47a of the chuck head 47 as shown in FIG. The 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. Because of the contact, the drive shaft 45 is connected to the chuck head 47.

At the same time, the pin 47b of the chuck head 47 is separated from the distal end of the release portion 53a by a distance a + b, and the chuck 47e enters the clamp 32b.

In addition, in order to adjust the movement distance a + b of the chuck head 47, it is only necessary to adjust the protrusion amount of the stopper part 57b by rotating the operation part 57a of the conveyance amount adjustment member 57. FIG.

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 and detects a part (convex portion of the cam surface of the cam 29a) irrelevant to the return operation of the drive shaft 45 and outputs a detection signal.

The timing sensor 58 is connected to the control terminal of the drive circuit 55a of the electronic switch 55, and the drive circuit 55a is provided with the electronic switch 55 while receiving the detection signal from the timing sensor 58. Prohibit the driving of.

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

When the cams 29a to 29j rotate with the operation of the electric motor 27, the upper blades 31b, the clamps 32b, and 35 are lowered.

When the phase angle of the electric motor 27 (actually, the rotation angle from the origin of the cams 29a to 29j) reaches 10 °, the clamps 32b and 35 move to the bottom dead center, and the clamp 35 is mounted on the mounting plate 32a. ) Is engaged with the pin 32c.

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 weft angle reaches 40 °, the upper edge 31b moves to the bottom dead center, and the sealing portion 3 of the continuous sealing member 1, which is sandwiched between the mounting plate 32a and the clamp 32b, is the upper edge 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 blade 31b moves to a bottom dead center at a phase angle of 40 ° and 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 fitted between the clamp 32b and the mounting plate 32a. Therefore, a space | interval is formed between the cutting terminal part of the sealing part 3 and the lower blade 31a, and between the cutting terminal part of the sealing part 3, and the upper blade 31b.

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

Incidentally, the ascending 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 starts to slide in the direction of the half arrow A (the conveying direction).

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 direction of the half arrow (A).

Since the release shaft 54 is in contact with the stopper portion 57b of the conveying amount adjusting member 57, the release shaft 54 is restricted in movement, and the drive shaft 45 slides about 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.

By this, the chuck head 47 is connected to the drive shaft 45.

Then, 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 release portion 53a of the release head 53 by the distance a + b. do.

When the phase angle reaches 130 ° and the drive shaft 45 moves to the maximum conveying position, the distance between the cutting end portion of the sealing portion 3 and the lower blade 31a, the cutting end portion of the sealing portion 3, The chuck 47e of the chuck head 47 enters the cutout portion 32d of the clamp 32b through the gap between the upper blade 31b and protrudes in the direction of the half arrow A of the clamp 32b.

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

Thereafter, once the phase angle reaches 155 °, the clamps 32b and 35 start to rise and stop the engagement between the clamp 35 and the pin 32c of the mounting plate 32a.

As a result, the mounting plate 32a rotates by its own weight and the mounting plate 32a is separated from the clamp 32b, thereby releasing the insertion of the continuous small sealing body 1 by the clamp 32b.

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

Further, 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, and the continuous small sealing member 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 an arrow A, and the sealing portion 3 of the continuous small encapsulation member 1 is supplied to the adsorption pads 13c and 14c, the adsorption pads 13c and 14c are disposed. 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.

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

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

Then, with the rotation of the lever 56, the pin 56b of the lever 56 is in compression contact with the release shaft 54, so that the slide of the release shaft 54 is constrained and the drive shaft 45 is released from the release head 53. And the release shaft 54 in the direction of the arrow A. FIG.

When the drive shaft 45 slides against 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 pushed in the direction of the half 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 stops moving. do.

By this, 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 descend from the top dead center.

When the phase angle reaches 360 °, the drive shaft 45 is moved to the maximum return position, and the series of operations described above 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 and to insert the small bag into the container, the electric motor 27 is moved. It is to be energized again after power cut off.

In the above embodiment, the transfer amount of the continuous sealing member 1 is controlled by disconnecting the drive shaft 45 and the chuck head 47 by moving the pin 47b of the chuck head 47.

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

Also, based on the output of the seam detection signal from the seam detection circuit 25, the distance "(a + b)" (dimension + accommodation part 2 and sealing part extending from the cutting means 31 to the boundary between the accommodation part 2 and the sealing part 3). After moving the chuck head 47 by the dimension from the boundary of 3 to the center part of the sealing part 3, the connection of the chuck head 47 and the drive shaft 45 is disconnected, and the conveyance operation of the continuous sealing member 1 is stopped. I was.

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 (a fixed position away from the boundary between the accommodating part 2 and the sealing part 3 by a distance b) It 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 affects the nonuniformity of the conveying speed of the continuous small sealing body 1 by the rotational nonuniformity of the electric motor 27, etc. The working position of the seal 3 can be reliably supplied to the lower blade 31a and the upper blade 31b without being received.

In addition, since the initial position (conveying 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 Even when the length dimension of the sealing part 3 is changed or when there is a manufacturing error in the apparatus, the central part of the sealing part 3 can be reliably supplied to the lower blade 31a and the upper blade 31b by correcting the dimensional change or the error. There is a number.

In addition, since the conveyance amount 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 half arrow A direction.

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 operation of stabbing the small bag.

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

(1) Insert the continuous small sealing body 1 into a pair of movable rollers, and detect a sealing part from the movement amount of the roller along the thickness direction of the continuous small sealing body 1.

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

However, in the case of the continuous small sealing member 1, in which the step between the receiving 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 is accurately identified. Can not.

Along with this, in the case of the device (1), contents such as seasonings are pressed and may be 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 possibility that the letters or the like printed on the continuous small package 1 are not discriminated from the front cover, or there is no difference in color between the front cover and the continuous small package 1, so that the label cannot 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 on the basis of 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.

At the same time, there are no unreasonable points such that letters printed on the continuous bag 1 are misidentified as a cover, or no color is detected between the label and the bag 1, so that no label 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, a suction force is applied to the continuous small container 1 from the suction pad 13c using the vacuum generator 17 and the intake passage 19, and the suction pad is used using the vacuum generator 18 and the intake passage 20. Adsorption force was exerted on the continuous small sealing body 1 from (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 suction heads 13 and 14 were installed so as to be movable, and a force was applied in the direction approached by the tension coil spring 15.

For this reason, the suction pads 13c and 14c press 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 continuous. The seal is stably detected without error because it follows the shape of 1).

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

For this reason, even when the conveyance position of the continuous sewage retainer 1 shifts up and down due to an error of the conveying mechanism or the conveyance position of the continuous sewage retainer 1 is moved up and down, the tension coil spring 16 is stretched to absorb the shank copper. For this reason, the sealing part 3 is stably detected also without a mistake.

In addition, the stoppers 24a and 24b regulate the access of the suction pads 13c and 14c, and in the access restriction state, the intervals larger than the thickness dimension of the sealing portion 3 are applied to 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 sealing member 1, so that the sealing part ( 3) is stably detected without error.

Further, the anti-curling protrusions 13e and 14e of the suction pads 13c and 14c guide the continuous small sealing member 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. 61, 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 prevention wall portions 13g and 14g.

For this reason, as shown in FIG. 60, since the adsorption amount by one of the adsorption pads 13c and 14c is excessive, and the other side can be prevented from being separated largely from the continuous bag 1, it is advantageous. Even in the sealing part 3, the sealing part 3 is stably detected without error.

By the way, in conveyance of the continuous small bag 1, the structure of following (1) and (2) base material is employ | adopted.

(1) A pair of rollers sandwiches the continuous small bag 1 and conveys the continuous small bag 1 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), as shown in FIG. 63 (a), the rollers and air cylinders are arranged on the half arrow (A) direction side of the cutting means 4, and the continuous small encapsulation member 1 is arrowed. It was extruded to the (A) direction side, and was supplied to the cutting means 4.

For this reason, especially when extruding 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 by mistake.

In addition, the continuous bag 1 is stored in a state of being folded in a meander, or rolled up in a roll.

For this reason, after cutting the sealing part 3, the continuous small sealing body 1 is extruded, and as shown in FIG. 63 (b), the sealing part 3 with a rounded bent habit at the time of storage will be attached to the cutting means 4, as shown in FIG. There was a case where the continuous small bag 1 could not be conveyed smoothly due to interference.

On the other hand, according to this embodiment, 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 by the chuck head 47 in the direction of the arrow A. The continuous sealing encapsulation member 1 was pulled while supplying the new sealing part 3 to the lower blade 31a and the upper blade 31b.

For this reason, since the cutting terminal part of the sealing part 3 with a bending habit can be grasped | stretched and tensioned, the cutting terminal 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 sealing member 1 is prevented from being bent at the time of conveyance, the continuous small sealing member 1 is collectively conveyed as set so that the sealing portion 3 is firmly secured between the lower blade 31a and the upper blade 31b. Can supply

In addition, in cutting the sealing part 3, the mounting part 32a and the clamp 32b were made to fit the sealing part 3 to it.

For this reason, the sealing part 3 is reliably cut | disconnected without rising.

In particular, when the contents are light or thin, the continuous small encapsulation member 1 may float due to the bending habit of the sealing portion 3, so that the continuous small encapsulation member 1 may be displaced. There was a shift from the sealing portion 3.

In contrast, in the present embodiment, the sealing portion 3 is fitted by the mounting plate 32a and the clamp 32b.

For this reason, since the bending habit of the sealing part 3 can be restrained and broken, the continuous small sealing body 1 is reliably cut | disconnected from the sealing part 93. As shown in FIG.

In addition, the sealing part 3 was cut | disconnected, and the conveyance part 1 was conveyed, and the sealing part 3 was opened by the mounting plate 32a and the clamp 32b.

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

In addition, the chuck 47e grips the cutting end of the sealing part 3 while the cutting end of the sealing part 3 is fixed between the mounting plate 32a and the clamp 32b.

For this reason, since the cutting end part of the sealing part 3 is reliably gripped without being influenced by the bending habit of the continuous small sealing body 1, the continuous small sealing body 1 is surely conveyed.

In addition, between the lower blade 31a and the cutting end portion of the sealing portion 3, the cutting end portion of the upper edge 31b and the sealing portion 3 and the moving plate 32a and the clamp 32b are moved. Formed a gap 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 gap.

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

For this reason, since the holding amount of the cutting terminal part by the chuck 47e becomes large, the continuous small sealing body 1 can be prevented from deviating from the chuck 47e by the movement of the chuck 47e.

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

Moreover, since the comb-shaped chuck 47e is used, even if oil or the like adheres to the surface of the continuous small encapsulation member 1, the continuous small encapsulation member 1 can be securely tensioned without slipping.

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 near the lower blade 31a and the upper blade 31b, a device becomes compact.

Next, a second embodiment of the present invention will be described with reference to FIGS. 27 and 28. FIG.

In addition, the same code | symbol is attached | subjected about the same member as 1st Embodiment mentioned above, and description is abbreviate | omitted and only a different member is demonstrated below.

First, in FIG. 27, the suction pads 13c and 14c are accommodated in the suction heads 13 and 14 so that the shanghai copper can be accommodated.

The joint detection circuit 25 is connected to the electromagnetic solenoids 59b and 60b via the driving circuits 59a and 60a, and the solenoids 59b and 60b connect the crank mechanisms 59c and 60c. It is connected to the suction pads 13c and 14c via.

Reference numeral 59 denotes a moving means composed of a drive circuit 59a, an electromagnetic solenoid 59b, and a crank mechanism 59c.

Reference numeral 60 denotes a moving means composed of a drive circuit 60a, an electromagnetic solenoid 60b, and a crank mechanism 60c.

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 59b 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. 62, 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 59b 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 in total.

In addition, in the second embodiment, the suction pads 13c and 14c are moved by the moving means 59 and 60, which are mainly the solenoids 59b and 60b. Alternatively, for example, the suction pads 13c and 14c may be moved by the moving means mainly of the electric motor, the moving means mainly of the cylinder, and the moving means mainly of the magnet.

In the second embodiment, both of the adsorption pads 13c and 14c are moved relative to the adsorption heads 13 and 14, but the adsorption pads 13c and 14c are moved to the adsorption head 13 or 14c. You may make it move about one side of (14).

In addition, in the first and second embodiments described above, the pressure switches 21 and 22 that are turned on / off in accordance with the pressure levels in the intake passages 19 and 20 are provided, but are not limited thereto. A pressure sensor which detects the pressure values in the 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, abbreviate | omits description, and only the other member is demonstrated next.

The suction force of the vacuum generator 17 is set less than that of 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.

Then, since the negative pressure in the intake passage 19 becomes large and the pressure switch 21 is turned off, 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 between 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 configuration of the joint detection circuit 61 is simplified, cost reduction of the apparatus is achieved.

In the above-described third embodiment, the vacuum generating devices 17 and 18 having different suction powers are used to reduce the suction power of the suction pad 13c to be smaller than the suction force of the suction pad 14c. For example, the adsorption area of the adsorption pad 13c may be less than that of the adsorption pad 14c, or the ventilation resistance of the intake passage 19 corresponding to the adsorption pad 13c may correspond to the adsorption pad 14c. 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, if the adsorption force of the adsorption pads 13c and 14c is exerted from one vacuum generator through a common intake passage, the device is further inexpensive. Become.

In addition, a belt conveyor type adsorbent may be used instead of the adsorption pad 14c having a large adsorption force.

The belt conveyor-type adsorption body is formed by forming a plurality of adsorption holes in the belt conveyor and conveys air while adsorbing air continuously through the adsorption hole while rotating the belt conveyor while always adsorbing the continuous small bag 1 to the belt conveyor.

Therefore, the suction pads 13c and 14c can be closed, and at the same time, the member associated with the suction pad 14c can be closed.

In this configuration, the drive of the belt conveyor may be the configuration of the twelfth and thirteenth embodiments described later.

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 may be 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 to detect the analog signal. A pressure sensor may be installed to output the pressure.

In this case, it is enough 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 adsorption 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.

Next, a fourth 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, abbreviate | omits description, and only the other member is demonstrated next.

The vacuum generator 62 is fixed to the base 11, and the intake pipe 63a is connected to the vacuum generator 62.

Intake pipes 63b and 63c are connected to the exhaust path 13d of the suction head 13 and the exhaust path 14d of the suction head 14 (see also FIG. 21).

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 turns off when the negative pressure in the intake pipe 63a becomes large, and turns on when the negative pressure in the intake pipe 63a changes to the positive pressure side, and is connected to the input terminal of the joint detection circuit 65.

According to the above embodiment, 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. As shown in 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, it is possible to cope with one pressure switch 64, and the circuit configuration of the seam detection circuit 65 is simplified, thereby reducing the cost of the apparatus.

In addition, in the fourth embodiment, the adsorption pads 13c and 14c are fixed to the adsorption heads 13 and 14, but are not limited thereto. For example, as in the third embodiment, an electromagnetic solenoid, an electric motor, At least one of the suction pads 13c and 14c may be moved relative to the suction heads 13 and 14 by means of moving means mainly composed of a cylinder, a magnet, or the like.

Next, a fifth 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 4th Example, abbreviate | omits description, and only the other member is demonstrated next.

In the pad accommodating part 14b of the adsorption head 14, the adsorption pad 14c is accommodated so as to be movable.

A compression coil spring 66 is interposed between the upper surface of the adsorption pad 14c and the upper wall of the pad receiving portion 14b. The compression coil spring 66 is a continuous encapsulation member (14c). 1) Applying 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 described above in Fig. 31, in the pad receiving portion 13b of the adsorption head 13, the adsorption pad 13c is housed so as to be movable, and the adsorption pad 13c is a compression coil spring 66. A force is applied to the side of the continuous bag (1) (upper side) and is positioned at an approaching position approaching (moving upward) the continuous 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 so that the receiving portion 2 of the continuous small sealing member 1 is placed in the corners of the suction heads 14 and 13. The suction surface of the suction pad 14c and the suction surface of the suction pad 13c are guided 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 suction 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 provided by the suction pads 13c and 14c. Adsorption is surely released.

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

Then, the adsorption 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 stably without a mistake totally.

Next, a sixth 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 5th Embodiment, abbreviate | omits description, and only the other member is demonstrated next.

The adsorption head 14 is equipped with a support head 68, and the adsorption pad 14c is inserted into the support head 68 so as to be movable.

In addition, a stopper 68a is formed in the support head 68, and the suction pad 14c is positioned in the approaching position with the contact with the stopper 68a.

In addition, as shown in parentheses in FIG. 32, the suction pad 13c is mounted to the suction head 13 in a state where the moving head is inserted into the support head 68 so as to be movable.

Reference numeral 68b denotes a curl prevention protrusion formed on the support head 68. As shown in FIG.

Reference numeral 68c denotes an enlarged opening preventing wall portion formed in the support head 68. As shown in FIG.

According to the above embodiment, as in the fifth embodiment, the suction pads 13c and 14c move in accordance with the adsorption and desorption of the continuous small sealing member 1, so that the sealing portion 3 can be reliably and stably detected. can do.

Furthermore, since the adsorption pads 13c and 14c can be mounted to the support head 68 and then the support heads 68 can be mounted to the adsorption heads 13 and 14, so that the adsorption pads 13c and 14c can be mounted. Installation workability is improved.

In addition, since the contents of the pad accommodating portions 13b and 14b become large, the adsorption pads 13c and 14c are tensioned with a strong force with the adsorption of the continuous small encapsulation member 1.

For this reason, the suction pads 13c and 14c are reliably moved in the direction away from the continuous small sealing member 1.

In addition, in the above-mentioned fifth and sixth embodiments, both of the adsorption pads 13c and 14c are exerted by the compression coil spring 66, but not limited thereto. One side may be configured to apply a force by the compression coil spring 66.

In this structure, since the suction pad 13c or 14c moves according to the pressure in the intake pipe 63a, the sealing part 3 can be reliably detected reliably.

Next, a seventh 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 5th Example, abbreviate | omits description, and only the other member is demonstrated next.

The suction pad 14c is integrally formed with a corrugated barrel portion 14i, and the migration pipe portion 14i is accommodated in the pad receiving portion 14b of the suction head 14 and fixed to the upper wall of the pad receiving portion 14b. have.

In addition, as shown in parentheses in FIG. 33, the suction pad 13c is integrally formed in the suction pad 13c, which is accommodated in the pad receiving part 13b of the suction head 13. It is fixed on the upper wall.

According to the above embodiment, as in the fifth embodiment, the corrugated barrel portion 13i of the adsorption pad 13c and the corrugated barrel portion 14i of the adsorption pad 14c are stretched in accordance with the adsorption and desorption of the continuous small sealing body 1. Since the suction pads 13c and 14c move, the sealing portion 3 can be detected reliably and stably.

Furthermore, since the corrugation cylinders 13i and 14i are integrally formed on the suction pads 13c and 14c, the suction pads 13c and 14c are moved by separate compression coil springs 66. In comparison, 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 the 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.

Therefore, as in the above-mentioned fifth to seventh embodiments, when the suction pads 13c and 14c are immediately moved away from the continuous sealing member 1 in accordance with the increase in the negative pressure (by the spring coil or the corrugated pipe part). One of the adsorption pads 13c and 14c adsorbs and moves the continuous small encapsulation member 1, and the other is far from the continuous small encapsulation member 1, so that the accommodation portion 2 cannot be adsorbed.

On the other hand, in the second embodiment described above, the suction pad 13c and 14c are separated from the continuous sealing member 1 by waiting for the accommodating part detection signal to be output from the joint detection circuit 25, and thus the suction pad 13c. ) And (14c) can prevent the adsorption and error of the accommodating part 2.

In addition, in the seventh embodiment described above, although the pleated cylinders 13i and 14i are formed on both sides of the suction pads 13c and 14c, the pleats are not limited thereto, but the one side of the suction pads 13c and 14c is pleated. It is good also as a structure which forms the cylinder part 13i and 14i.

In this case, since the suction pads 13c and 14c move in accordance with the pressure in the intake pipe 63a, the sealing portion 3 can be reliably and stably detected.

In the fourth to seventh embodiments described above, the pressure switch 64 is turned on and off depending on the pressure level in the intake pipe 63a. However, the pressure switch 64 is not limited thereto. For example, the pressure value in the intake pipe 63a is detected. A pressure sensor that outputs an analog signal may be provided.

In this case, it is enough to detect that the negative pressure in the intake pipe 63a changes to the positive pressure side by comparing the output signal from the pressure sensor with the reference value.

In the first to seventh embodiments, the cylindrical pin 47b is accommodated in the accommodating portion 47a of the chuck head 47, but the present invention is not limited thereto. You may accept the pin.

In particular, when accommodating a pin having a concave portion, the chuck head 47 slides against the drive shaft 45 because the drive shaft 45 is engaged with the concave portion of the pin and the contact area between the drive shaft 45 and the pin increases. Can be prevented.

Along with this, wear of the drive shaft 45 and the pins can be prevented.

In the first to seventh embodiments described above, one release portion 53a is formed in the release head 53. However, the release head 53 is not limited thereto, and two or more release portions 53a may be formed.

In this configuration, the number of the pins 47b may be two or more, depending on the number of the release portions 53a.

In the above first to seventh embodiments, the drive shaft 45 having a circular cross section is used, but the present invention is not limited thereto. For example, a polygonal drive shaft or a drive shaft having a D cut portion is used. The pin 47b may be contacted.

In this configuration, since the contact area between the drive shaft and the pin 47b increases, the chuck head 47 is reliably prevented from sliding against the drive shaft 45.

At the same time, wear of the drive shaft 45 and the pins is prevented.

Next, an eighth embodiment of the present invention will be described with reference to FIGS. 34 to 37. FIG.

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

First, in FIG. 34, a drive shaft 45 is slidably inserted into the chuck head 47, and a disk-shaped stopper 45a corresponding to the return head is located in the drive shaft 45 in the direction of the arrow A direction. Is provided, and the first concave portion 45b, which is located in the half arrow A direction of the stopper 45a and forms a semicircular arc, is formed.

The chuck head 47 is provided with an accommodating portion 47g that is open to the drive shaft 45 side and the release shaft 54 side.

The accommodating portion 47g has a circular long hole shape in cross section, and a cylindrical pin 47h is accommodated in the accommodating portion 47g.

And this pin 47h is engaged in the recessed part 45b of the drive shaft 45, and the chuck head 47 is connected to the drive shaft 45. As shown in FIG.

In addition, the pin 47h corresponds to the connecting means.

A second concave portion 54b disposed on the release shaft 54 in the direction of the direction of arrow A and provided with a disc stopper 54a, and positioned in the half arrow A direction of the stopper 54a to form a semicircular arc. ) Is formed.

As shown in FIG. 37, the drive shaft 45 moves the maximum amount in the direction of the half arrow A, and the half arrow A direction terminal of the release shaft 54 is connected to the stopper 57b of the conveying amount adjusting member 57. In the abutting state, the distance between the stoppers 45a and 54a, the center of the concave portion 45b and the center of the 54b are set to be (a + b).

In addition, both surfaces of the first concave portion 45b and the inner surfaces of the second concave portion correspond to the inclined surface as apparent from the description below.

In the present embodiment, the release shaft 54 corresponds to the second moving means.

Next, the operation of the above configuration will be described.

First, in FIG. 37, when the drive shaft 45 moves from the maximum return position to the arrow A direction (transfer direction), the kinetic force of the drive shaft 45 is transmitted to the chuck head 47 via the pin 47h and the chuck The head 47 moves integrally with the drive shaft.

Thereby, the continuous small sealing body 1 gripped by the chuck 47e of the chuck head 47 is conveyed in the direction of an arrow A. As shown in FIG.

At the same time, the release shaft 54 is integrally moved with the chuck head 47 and the drive shaft 45 by the frictional force between the release shaft 54 and the chuck head 47.

Thereafter, when the sealing portion 3 of the continuous small sealing member 1 is supplied to the suction pads 13c and 14c and the seam detection signal is output from the seam detection circuit 25, the release shaft is energized by the energization of the electronic switch 55. Movement of 54 is constrained (see FIG. 34), and the chuck head 47 and the drive shaft 45 move in the direction of the arrow A with respect to the release shaft 54.

And when this movement amount reaches (a + b), as shown in FIG. 36, the chuck head 47 will contact the stopper 54a of the release shaft 54. As shown in FIG.

At the same time, the pin 47h engaged in the recessed portion 45b of the drive shaft 45 opposes the recessed portion 54b of the release shaft 54.

In this state, when the drive shaft 45 moves in the direction of the arrow A, it is pressed by the inner surface of the recessed part 45b of the drive shaft 45, and the pin 47h is extruded toward the release shaft 54 along the accommodating part 47g. .

The pin 47h is passed from the recessed portion 45b of the drive shaft 45 to the recessed portion 54b of the release shaft 54 and the connection between the drive shaft 45 and the chuck head 47 is released.

By this, the 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.

Thereafter, as shown in FIG. 35, when the drive shaft 45 moves the maximum amount in the direction of the arrow A and starts to move in the direction of the half arrow A (the return direction), the release shaft 54 is cut by the interruption of the electronic switch 55. FIG. ) Is released.

Then, a slight slip is generated between the composition shaft 45 and the chuck head 47, so that the stopper 45a of the drive shaft 45 contacts the chuck head 47 and maintains the state shown in FIG. 45, the chuck head 47, and the release shaft 54 slide in the half arrow A direction.

When the drive shaft 45, the chuck head 47, and the release shaft 54 slide in the direction of the half arrow A, and the release shaft 54 abuts against the stopper portion 57b of the conveying amount adjusting member 57, the release shaft 54 is released. The movement of the shaft 54 is constrained and the drive shaft 45 and the chuck head 47 slide in the direction of the half arrow A with respect to the release shaft 54.

Then, it is pressed by the inner surface of the recessed part 54b of the release shaft 54, and the pin 47h is extruded toward the recessed part 45b side of the drive shaft 45 with the accommodating part 47g.

As a result, the pin 47h is transferred from the recess 54b of the release shaft 54 to the recess 45b of the drive shaft 45.

Thereafter, when the movement of the drive shaft 45 in the direction of the half arrow A is stopped, as shown in FIG. 37, the recess 45b and 54b between the stoppers 45a and 54a are separated by (a + b). Return to the separated initial state.

The series of operations described above is repeated.

However, in the first embodiment described above, as shown in Figs. 9 to 11, the drive shaft 45 and the chuck head are brought into compression contact with the inner surface of the housing portion 47a and the outer peripheral surface of the drive shaft 45. The connection between the drive shaft 45 and the chuck head 47 is interrupted while the pin 47b is pushed by the release portion 53a of the release head 53.

For this reason, if the connection interruption between the drive shaft 45 and the chuck head 47 is repeated, the outer circumferential surface of the drive shaft 45, the inner surface of the receiving portion 47a, and the outer circumferential surface of the pin 47b are worn out. There is a fear that sufficient connection force may not be obtained.

Therefore, it is necessary to check the wear condition of each member frequently and replace the wear parts by stopping the production line if wear is found.

On the other hand, mass production equipment such as bag-feeding equipment is required to be easy to operate for a long time with little maintenance work.

To improve this, it can be considered that the wear part is lacquered or the wear part is formed of a hard member such as ceramic, but the cost is increased.

Advantages In the eighth embodiment described above, the drive shaft 45 and the chuck head 47 are disconnected by passing the pin 47h between the drive shaft 45 and the release shaft 54.

For this reason, the durability of the drive shaft 45, the chuck head 47, and the pin 47h is improved.

Therefore, the effort of checking the wear state of each member and the effort of replacing the wear parts by stopping the production line can be reduced at the lowest cost.

When the stopper 45c of the drive shaft 45 abuts on the stopper 54c of the release shaft 54, the distance between the stoppers 45d and 54c between the recessed portions 45b and 54b is (a + b). Is maintained.

Next, the operation of the above-described configuration will be described.

When the drive shaft 45 moves in the direction of the arrow A from the maximum return position shown in FIG. 44, the chuck head 47 presses the stopper 54c through the compression coil spring 54e. It moves integrally with the chuck head 47 and the drive shaft 45.

After that, when the seam detection signal is output from the seam detection circuit 25, the movement of the release shaft 54 is restrained.

Then, since the chuck head 47 presses the compression coil spring 54e, the drive shaft 45 and the chuck head 47 compress the compression coil spring 54e in the direction of the arrow A with respect to the release shaft 54. Move.

When this movement amount reaches (a + h) and exceeds this, as shown in FIG. 45, the pin 47h is received by the recessed portion 54b of the release shaft 54 from the recessed portion 45b of the drive shaft 45. Is passed.

Even in this configuration, the continuous small bag 1 can be held in a non-slip state by the chuck.

In the above first to eleventh embodiments, the drive circuit 55a disconnects the electronic switch 55 after a predetermined period of time after the seam detection signal is output from the seam detection circuit 25. However, this is limited. For example, the timing sensor 58 detects the inversion timing of the drive shaft 45 from the convex portion of the cam surface of the cam 29a so that the drive circuit 55a based on the detection signal from the timing sensor 58. It is good also as a structure which cuts off the electronic switch 55. FIG.

Next, a twelfth embodiment of the present invention will be described with reference to FIGS. 47 to 52. FIG.

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

First, in Fig. 47, an electric motor (not shown) corresponding to a driving source is connected to the rotating shaft 71 corresponding to the first moving means, and the rotating shaft 71 rotates in the direction of the arrow D when the electric motor operates. .

The rotating shaft 71 is inserted through the cogwheel-shaped rotating body 72 corresponding to the conveying means.

The rotating body 72 is provided with a tapered accommodating portion 73a and a rotating shaft 71 and a concentric circular arc portion 73e, which extend toward the half arrow E, and are connected within the accommodating portion 73a. The pin 73b corresponding to a means is accommodated.

Moreover, the accommodating part 73a is connected to the circular arc part 73e.

An attachment member 73c is attached to the rotating body 72.

Two compression coil springs 73d (see FIG. 48) are attached to the front end of the attachment member 73c, and each of these springs 73d is placed on the narrow side of the receiving portion 73a (arrow E direction). The pin 73b is in compression contact with the inner surface of the housing portion 73a and the outer circumferential surface of the rotational shaft 71 along with pressing the pin 73b.

As a result, the pin 73b is held in the connected state, and the rotating body 72 is connected to the rotating shaft 71 so as to rotate in the direction of the arrow D integrally with the rotating shaft 71.

Reference numeral 73 denotes a driving force transmission means composed of the receiving portion 73a, the pin 73b, the attachment member 73c, and the compression coil spring 73d.

The rotating body 72 is equipped with a chain 74 and when the rotating body 72 is rotated in the direction of the arrow D by the operation of the electric motor, the chain 74 moves so that the continuous sealing body 1 is conveyed. have.

Moreover, as shown in FIG. 48, the rotating body 72 is equipped with the circular release body 76 via the torsion coil spring 75. As shown in FIG.

In addition, the rotating body 76 corresponds to the second moving means, and the rotational force of the rotating body 72 is transmitted to the release body 76 via the spring 75 in a state where no restraining force is applied to the release body 76. And the release body 76 rotates integrally with the rotary body 72.

In addition, the motor is connected to a drive circuit (not shown), which drives the motor intermittently by a certain amount.

As shown in FIG. 49, the releasing member 76 is provided with a convex release portion 76a corresponding to the releasing means. The releasing portion 76a is formed in the arc portion 73e as shown in FIG. It is accommodated in the direction of the arrow (E).

Therefore, in the state where the restraining force is not acting on the releasing body 76 and the releasing body 76 is rotated integrally with the rotating body 72 in the direction of arrow D, the releasing part 76a of the releasing body 76 is Is held in the direction of the arrow E in the arc portion 73e.

As shown in FIG. 52, the pin 78c of the lever 78 is rotatably inserted into the base 77 shown in FIG.

Pins 77b and 78a are fixed to the base 77 and the lever 78, and tension coil springs 79a are attached to the pins 77b and 78a.

As shown in FIG. 50, an electronic switch 80 made of an electromagnetic solenoid is fixed to the base 77. As shown in FIG.

The electronic switch 80 is connected to the output terminal of the joint detection circuit 25, and one end of the tension coil spring 79b is connected to the flan 80a of the electronic switch 80.

As shown in FIG. 51, the pin 78b is fixed to the lever 78, and the other end of the tension coil spring 79b is connected to the pin 78b.

Reference numeral 81 denotes a restraining means composed of a lever 78 and an electronic switch 80.

Next, the operation of the above configuration will be described.

The electronic switch 80 is disconnected in the state in which the accommodating part 2 of the continuous small sealing body 1 passes through the suction pads 13c and 14c, and the accommodating part detection signal is output from the joint detection circuit 25. .

For this reason, the planar 80a of the electronic switch 80 protrudes, and the lever 78 is hold | maintained apart from the releasing body 76. As shown in FIG.

Therefore, since the restraining force does not act on the release body 76 from the lever 78, the rotational force of the electric motor is transmitted from the rotating shaft 71 to the rotating body 72 through the pin 73b, and the chain 74 moves.

By this, the continuous small bag 1 is conveyed.

Thereafter, when the sealing portion 3 of the continuous small sealing member 1 is supplied to the suction pads 13c and 14c, and the seam detection signal is output from the seam detection circuit 25, the electronic switch 80 is energized.

Then, the planar 80a of the electronic switch 80 enters against the force of the spring of the tension coil spring 79a, and the lever 78 is kept in compression contact with the release body 76 as shown in FIG. do.

Therefore, since the restraining force acts on the release body 76 from the lever 78, the rotation of the release body 76 is restrained.

When the rotation of the release body 76 is restrained, only the rotating body 72 rotates in the direction of the arrow D against the force of the spring of the torsion coil spring 75.

And when the pin 73b engaged with the inner surface of the accommodating part 73a moves to the release part 76a side of the release body 76, and touches the release part 76a, the pin 73b is the accommodating part 73a. It is moved to the wide side (half arrow E direction) in the inside, and becomes the blocking state separated from the inner surface of the accommodating part 73a, and the outer peripheral surface of the rotating shaft 71. FIG.

Because of this, the rotational force of the electric motor is not transmitted to the rotating body 72, and as a result, the chain 74 stops.

When the chain 74 stops, the conveyance of the continuous small sealing body 1 is stopped, and the center part of the sealing part 3 is supplied between the lower blade 31b and the upper blade 31a.

Then, the clamp 32b engages the sealing portion 3 of the continuous small encapsulation member 1, and then the upper blade 31a is lowered to cut the sealing portion 3 so that the small bag is separated from the continuous small encapsulation member 1. do.

In addition, the moving distance (dimensions of the arc portion 73e) of the pin 73b is set in advance so that the continuous small bag 1 is conveyed by (a + b) by the chain 74.

When the sealing part 3 is cut, the electric motor and the electronic switch 80 are disconnected, and the lever 78 rotates about the pin 78c by the force of the spring of the tension coil spring 79a, and from the release body 76, Return to the separated initial state.

Since the restraining force does not act on the release body 76 from the lever 78, the release body 76 rotates with respect to the rotating body 72 by the restoring force of the torsion coil spring 75. The release part 76a returns to the initial state which abuts on the narrow side of the accommodating part 73a.

And with the operation of the electric motor, the above-described series of operations are repeated.

In addition, the force of the spring of the tension coil spring 79b is set larger than the force of the spring of the tension coil spring 79a.

According to the above embodiment, the rotation shaft 71 and the rotating body 72 are disconnected by moving the pin 73b in the receiving portion 73a to control the conveyance amount of the continuous small sealing body 1.

This eliminates the need for expensive electrical means, such as movement measurement means and controllers, to reduce the cost of the device.

In the twelfth embodiment, the torsion coil spring 75 is connected between the rotating body 72 and the releasing member 76. However, the present invention is not limited thereto and may be connected by, for example, frictional force.

In this configuration, the restraint of the canceller 76 is released, and the motor is reversed to return the canceller 76a of the canceller 76 to its initial position.

Next, a thirteenth embodiment of the present invention will be described with reference to Figs.

Incidentally, the same members as those in the twelfth embodiment will be denoted by the same reference numerals and the description thereof will be omitted, and only the other members will be described next.

First, in FIG. 54, the pin 72a protrudes from the rotating body 72, and the accommodating part 76b which makes an arc shape is formed in the releasing body 76 as shown in FIG.

Next, the operation of the above configuration will be described.

In the state where the restraining force is not applied to the release body 76, the rotational force of the electric motor is transmitted from the rotating shaft 71 to the rotating body 72 via the pin 72d, and the chain 74 moves so that the continuous small sealing body 1 moves. It is conveyed in the direction of an arrow E.

At the same time, the releasing member 76 transmits the rotational force of the rotating body 72 via the torsion coil spring 75, and rotates integrally with the rotating body 72 in the direction of the arrow D.

Thereafter, when the sealing portion 3 of the continuous small sealing member 1 is supplied to the suction pads 13c and 14c and the seam detection signal is output from the seam detection circuit 25, the electronic switch 80 is energized and the release body ( Rotation of 76 is constrained.

Then, the rotating shaft 71 and the rotating body 72 rotate with respect to the release body 76 in the direction of arrow D, and the torsion coil spring 75 is twisted.

When the rotation amount 71 of the rotating shaft 71 and the release body 76 of the rotating body 72 reaches a + b, the pin 72a of the rotating body 72 receives the receiving portion 76b of the release body 76. The inner surface of the side in the direction of the arrow (D) in the contact with the inner surface.

In this case, the dimension of the accommodating part 76b is preset so that it may become the moving distance of the pin 72a which is required for the continuous small sealing body 1 to move by (a + b).

At the same time, the pin 72d faces the concave portion 76b of the release body 76, and only the rotation shaft 71 rotates in the direction of the arrow D. FIG.

Then, the inner surface of the concave portion 71a of the rotating shaft 71 is pressed, so that the pin 72d is delivered from the concave portion 71a of the rotating shaft 71 to the concave portion 76c of the release body 76, and the rotating shaft 71 ) Is disconnected from the rotating body 72 and the rotating body 72 is connected to the release body 76 via a pin 72d.

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

Then, when the upper blade 31b is lowered and the sealing part 3 is cut between the lower blade 31a and the upper blade 31b, the electronic switch 80 is disconnected and the restraint of the release body 76 is released.

Then, when the rotating shaft 71 rotates again in the direction of the arrow D, and the pin 72d faces the concave portion 71a of the rotating shaft 71, the restoring force of the torsion coil spring 75 is It presses against the inner surface of the recessed part 76c, and the pin 72d is extruded to the rotating shaft 71 side along the accommodating part 72c.

As a result, the pin 72d is passed from the recessed portion 76c of the release body 76 to the recessed portion 71a of the rotational body 71 and the connection between the releaser 76 and the rotational body 72 is released. The pin 72a of the rotating body 72 is brought into contact with the inner surface of the direction of the half arrow D in the receiving portion 76b of the release body 76 by the restoring force of the torsion coil spring 75 again. The release body 76 rotates until the rotation body 72 is connected to the rotation shaft 71 and returns to the initial state.

The series of operations described above is repeated.

In the first to fourteenth embodiments, the adsorption pads 13c and 14c are arranged in the horizontal direction crossing at right angles to the conveying direction of the continuous small sealing body 1 and the conveying direction. Alternatively, for example, as shown in Fig. 57 of the fifteenth embodiment of the present invention, the arrangement may be displaced in the horizontal direction crossing at right angles to the conveying direction.

In this configuration, even when the space between the suction pads 13c and 14c is reduced, the suction pads 13c and 14c are mutually reduced in conveying the thin continuous bag 1 containing the laver and the like. Since there is no adsorption, the sealing portion 3 is stably detected without error.

In the above first to fifteenth embodiments, the mounting plate 32a is rotated in conjunction with raising the clamp 35 by engaging the clamp 35 with the pin 32c of the mounting plate 32a. For example, it may be configured as shown in FIG. 58 showing the sixteenth embodiment of the present invention.

In the configuration of FIG. 58, the compression coil spring 32d is interposed between the mounting plate 32a and the base 26. When the clamp 32b is lowered, the compression coil spring 32d is mounted by the elastic return force. The seal 3 is sandwiched between the plate 32a and the clamp 32b.

When the clamp 32b is raised, the mounting plate 32a is rotated while the sealing portion 3 is sandwiched between the mounting plate 32a and the clamp 32b by the elastic return force of the compression coil spring 32d.

When the mounting plate 32a abuts against the pin 30b of the frame 30, rotation stops and only the clamp 32b rises, so that the fitting of the sealing portion 3 is released.

Reference numeral 32e denotes a core rod of the compressed coil spring 32d.

In addition, in the first to sixteenth embodiments, the sealing part is detected by releasing the adsorption by at least one of the adsorption heads 13 and 14c, but the present invention is not limited thereto. The cover is printed on the sealing part and the cover is read by the photoelectric sensor, or the continuous small bag 1 is fitted by a pair of rollers, and the amount of movement of the roller along the thickness direction of the continuous small bag 1 is detected. It is good also as a structure.

In the above first to sixteenth embodiments, the mounting plate 32a and the clamp 32b are moved to separate the cutting end of the sealing portion 3 from the lower blade 31a and the upper blade 31b.
