Abstract

PROBLEM TO BE SOLVED: To supply works to an operating device by a cheap configuration without using a measuring means and a control apparatus. SOLUTION: A chuck head 47 is loaded on a drive shaft 45 through a driving force transmitting means, and when the driving force transmitting means is coupled to the drive shaft, a continuous small bag-body held by a chuck 47e of the chuck head 47 is conveyed together with the drive shaft 45. When a seal part of the continuous small bag-body is detected in this state, the chuck head 47 is moved a specified distance, and then the driving force transmitting means is switched to a de-energized state. In this case, since the relation between the drive shaft 45 and the chuck head 47 is interrupted, the conveyance of the continuous small bag-body is stopped, and the seal part is supplied to a cutting means.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for conveying a work piece which supplies the work piece to the work apparatus when the work apparatus performs a predetermined work on the work piece.

[0002]

FIG. 59 shows a continuous pouch 1 which is an example of a work piece. The continuous pouch 1 is in the form of a strip having alternating accommodating portions 2 and sealing portions 3, and each accommodating portion 2 stores a cup noodle soup, soup or the like. When separating the continuous pouch body 1 into a plurality of pouches, the seal portion 3 is detected by the seam detection means while the continuous pouch body 1 is conveyed in the direction of arrow A,
The continuous pouch 1 is cut from the seal portion 3 by supplying the seal portion 3 to the working device having the cutting blade based on the detection signal from the seam detection means.

Conventionally, in order to control the transport amount of the continuous pouch 1 and supply the seal portion 3 to the working device, the transport device described in (1) below has been used. The following devices are disclosed in Japanese Examined Patent Publication No. 62-38228 and Japanese Patent Publication No.
This is disclosed in Japanese Patent No. 7258.

(1) The continuous pouch 1 is conveyed as the feed roller rotates. Then, the pulse oscillator is driven in accordance with the rotation of the feed roller to detect the carry amount of the continuous pouch body 1, and when a certain number of pulses are output from the pulse oscillator in response to the output signal from the joint detecting means. Stop the feed roller motor. However, in the above conventional device, in addition to the movement amount measuring means such as the pulse oscillator, a control device such as a microcomputer or a sequencer for controlling the motor based on the output signal from the pulse oscillator is required, so that the device becomes expensive. Become.

Therefore, it has been considered that a relatively inexpensive member such as a delay circuit is used and a stop signal output in response to a detection signal from the seam detection means is delayed by a set time and then given to the motor. However, in this configuration,
If the rotation speed of the motor varies due to fluctuations in load or voltage, the seal portion 3 will not be supplied to the work device even if the stop signal is given to the motor with a delay of a set time. For this reason, after all, it becomes necessary to control the amount of rotation of the motor by using the above-described measuring means and control device, and it is not possible to achieve the original cost reduction.

In addition, when the fixed number of pulses are output from the output of the seam detection signal, the motor of the feed roller is stopped, or the stop signal is delayed from the output of the seam detection signal by the set time to provide the stop signal. If the length of the portion 2 along the direction of the arrow A varies, the central portion (working position) of the seal portion 3 cannot be reliably supplied to the cutting means 4.

The present invention has been made in view of the above circumstances, and an object thereof is to reliably supply a work position of a work to a working device with an inexpensive structure that does not use measuring means or control equipment. An object of the present invention is to provide a work device transporting device capable of performing work.

[0008]

According to a first aspect of the present invention, there is provided an apparatus for transporting a work, wherein the work apparatus supplies the work to the work apparatus when the work apparatus performs a predetermined work on the work. A first moving unit and a second moving unit that move by a driving force, a conveying unit that conveys a work piece, and a conveying unit that connects the first moving unit to the conveying unit. The connecting means for moving together with the first moving means, the detecting means for detecting the predetermined position of the work piece, and the movement of the second moving means are restrained as the detection signal is output from the detecting means. Restraint means,
A distance “a + b” (where a is a distance between a detection position of the detection means and a work position of the working device) provided on the second moving means, and the conveyance means is a distance between the work object and the work object. The distance between the detected position of the work piece by the means and the work position of the work piece by the working device), the moving direction of the connecting means by the moving distance of the connecting means required to move the connecting means. A second release means, which is spaced apart forward, for releasing the connection between the first moving means and the conveying means by the connecting means;
When the restraint means is restrained, the releasing means is configured to actuate the connecting means as the connecting means moves by the movement distance with respect to the releasing means.

According to the above means, the driving force of the driving source is transmitted from the first moving means to the conveying means via the connecting means in a state where the predetermined position of the work piece has not passed through the detecting means, and the conveying means conveys it. As the means moves, the work piece is conveyed toward the work device. At the same time, the second moving means moves together with the first moving means and the conveying means. After that, when the predetermined position of the work piece passes through the detection means, the restraint means operates and the restraint force acts on the second moving means from the restraint means.

Then, the connecting means moves a distance "a + b" with respect to the releasing means, and the releasing means actuates the connecting means to release the connection between the first moving means and the conveying means. As a result, the driving force of the drive source is not transmitted to the conveying means, so that the conveying means stops and the work position of the work piece is supplied to the work position of the work device. Therefore, expensive electric means such as a movement amount measuring means and a control device are not required, and the cost of the apparatus is reduced.

A protruding releasing portion 53a corresponding to the releasing means is formed. Then, when the slide of the release shaft 54 is restricted due to the output of the seam detection signal, the drive shaft 45
The chuck head 47 slides integrally with the release head 53 in the direction of arrow A, and the release portion 53a of the release head 53 enters the accommodation portion 47a of the chuck head 47 as shown in FIG. .

Then, since the releasing portion 53a pushes and moves the pin 47b of the chuck head 47 in the direction opposite to the arrow A,
The pin 47b is separated from the inner surface of the accommodating portion 47a and the outer peripheral surface of the drive shaft 45 to be in a blocking state, the connection between the drive shaft 45 and the chuck head 47 is released, and the transport of the continuous pouch 1 is stopped.

The amount of movement of the drive shaft 45 is set larger than the amount of conveyance of the continuous pouch body 1. Therefore, the drive shaft 45 slides in the arrow A direction even after the release shaft 54 and the chuck head 47 are restrained from sliding.

FIG. 19 shows the positional relationship between 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 head 14 (13), that is, the distance from the detection position of the detection means to the work position of the work device. Further, b is the distance between the boundary between the housing portion 2 and the seal portion 3 and the central portion of the seal portion 3, that is, the distance from the detected position of the work piece to the work position, as shown in FIG. , Release section 53a
A gap having a width dimension (a + b) is formed between the tip of the pin and the pin 47b of the chuck head 47. In addition, a
Is the length dimension of the accommodating portion 2 (pitch between detected positions)
It is set shorter.

Therefore, as shown in FIG. 19, when the boundary between the housing portion 2 and the seal portion 3 is supplied to the suction heads 13 and 14, a seam detection signal is output, and the electromagnetic switch 55 operates to release the release shaft. After the drive shaft 45 and the chuck head 47 slide in the direction of arrow A by the moving distance (a + b) after 54 is restrained,
As shown in FIG. 10, the releasing portion 53a of the releasing 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. Thereby, the conveyance of the continuous pouch 1 is stopped, and the central portion of the seal portion 3 is supplied to the lower blade 31a and the upper blade 31b.

The drive circuit 55a of the electromagnetic switch 55 disconnects the electromagnetic switch 55 when the drive shaft 45 starts moving in the direction opposite to the arrow A after reaching the maximum feed position by moving the drive shaft 45 by the maximum amount. Is configured. Then, as shown in FIGS. 18 to 17, the plunger 55b projects in the direction opposite to the arrow A by the spring force of the compression coil spring 55d, and the lever 56 rotates about the shaft 56a. As a result, the gap between the restraint member 26a and the pin 56b is expanded, and the restraint of the release shaft 54 by the pin 56b is released.

As shown in FIG. 10, a push-back rod 46a extending in the direction opposite to the arrow A is attached to the push-back head 46. Then, when the drive shaft 45 slides in the direction opposite to the arrow A in the state where the restraint of the release shaft 54 is released, from the state shown in FIG. 10, between the drive shaft 45 and the release head 53, the chuck head 47 and the drive shaft 45. Due to a slight slip between the push-back rod 46a and the chuck head 47, the push-back head 46, the chuck head 47, the release head 53, and the release shaft 54 move in the opposite arrow A direction. It is designed to slide together.

A conveyance amount adjusting member 57 corresponding to an adjusting means is attached to the support head 41. The transport amount adjusting member 57 has an operating portion 57a and a stopper portion 57b. When the drive shaft 45 and the release shaft 54 slide in the direction opposite to the arrow A, the release shaft 54 comes into contact with the stopper portion 57a and the release shaft. 5
4 movement is regulated.

As a result, the drive shaft 45 slides in the direction opposite to the arrow A with respect to the release shaft 54, and FIG.
As shown in FIG. 1, the release portion 53a of the release head 53 is removed from the housing portion 47a of the chuck head 47. Then, the pin 47b of the chuck head 47 is compressed by the compression coil spring 47c.
The spring force causes the chuck head 47 to be connected to the drive shaft 45 because it projects in the direction of the arrow A and comes into pressure contact with the inner surface of the housing portion 47a and the outer peripheral surface of the drive shaft 45. Along with this, the pin 47b of the chuck head 47
Is separated from the tip of the releasing portion 53a by a distance (a + b), and the chuck 47e enters into the clamp 32b.

The moving distance of the chuck head 47 (a +
To adjust b), the operation portion 57 of the conveyance amount adjusting member 57 is used.
The amount of protrusion of the stopper portion 57b may be adjusted by rotating a. Further, the length dimension of the push-back rod 46 a is determined by the distance (a + a) between the chuck head 47 and the release head 53.
It is set longer than b).

As shown in FIG. 1, a timing sensor 58 is attached to the base 26. The timing sensor 58 is arranged close to the cam surface of the cam 29a, detects a portion unrelated to the feeding operation of the drive shaft 45 (a convex portion of the cam surface of the cam 29a), and outputs a detection signal. The timing sensor 58 is connected to the drive circuit 55a of the electromagnetic switch 55, and the drive circuit 55a prohibits the drive of the electromagnetic switch 55 while receiving the detection signal from the timing sensor 58.

FIG. 26 is a time chart of a series of pouch loading operations, and hereinafter, the operation of the above configuration will be described mainly with reference to FIG. With the operation of the motor 27, the cams 29a-2
When 9j rotates, the upper blade 31b and the clamps 32b and 35 descend. And the phase angle of the motor 27 is 10 °
The clamps 32b and 35 move to the bottom dead center, the clamp 35 moves to the pin 32c of the mounting plate 32a.
Engages. At the same time, the seal portion 3 of the continuous pouch 1 is sandwiched between the clamp 32b and the mounting plate 32a. After this, when the phase angle reaches 20 °, the chuck 47
When e goes from the closed state to the open state and the phase angle reaches 30 °, the push rod 39 descends from the top dead center.

When the phase angle reaches 40 °, the upper blade 31b moves to the bottom dead center, and the seal portion 3 of the continuous pouch 1 sandwiched between the mounting plate 32a and the clamp 32b causes the upper blade 31b and the lower blade to move. 31a, the phase angle is 55 °.
When it reaches, the chuck 47e is opened. Upper blade 3
After moving to bottom dead center at a phase angle of 40 °, 1b starts rising at a phase angle of 45 ° and reaches 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, the pouch separated from the continuous pouch body 1 is knocked down, and is thrown into the lower container. At the same time, the clamps 32b and 35 start to rise, and the tip end of the mounting plate 32a inclines upward while the cut end of the seal portion 3 is held between the clamp 32b and the mounting plate 32a. Cutting edge and lower blade 31
A gap is formed between the cutting edge of the seal portion 3 and the upper blade 31b.

The push rod 39, after moving to the bottom dead center, starts to rise at a phase angle of 65 ° and a phase angle of 105 °.
Reaches top dead center at. Further, the raising operation of the clamps 32b and 35 is temporarily stopped at the phase angle of 80 °.

When the phase angle reaches 60 °, the drive shaft 45 at the maximum feed position starts sliding in the direction opposite to arrow A. Then, the drive circuit 55a disconnects the electromagnetic switch 55, so that the restraint of the release shaft 54 is released, and the release head 53 and the release shaft 54 are held while the push-back rod 46a of the push-back head 46 is in contact with the chuck head 47. , The chuck head 47 moves in the opposite arrow A direction.

When the release shaft 54 comes into contact with the stopper portion 57b of the transport amount adjusting member 57, the movement of the release shaft 54 is restricted and the drive shaft 45 slides with respect to the release shaft 54.
The release portion 53a of the is removed from the housing portion 47a of the chuck head 47. As a result, the chuck head 47 is connected to the drive shaft 45. After this, the phase angle is 130 °
Drive shaft 45 moves to the maximum return position, the release portion 53a of the release head 53 is separated from the pin 47b of the chuck head 47 by a distance (a + b).

When the phase angle reaches 130 ° and the drive shaft 45 moves to the maximum return position, the gap between the cut end of the seal part 3 and the lower blade 31a, the cut end of the seal part 3 and the upper end. The chuck 47e of the chuck head 47 passes through the gap between the blade 31b and the notch 3 of the clamp 32b.
It enters into 2d and protrudes in the direction opposite to the arrow A direction of the clamp 32b. Along with this, the chuck 47e moves from the open state to the closed state.

After that, when the phase angle reaches 155 °, the clamps 32b and 35, which have been stopped temporarily, start moving upward, 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 clamped by the clamp 32b.
Since it is separated from the continuous pouch 1 by the clamp 32b
The pinching of is released. At the same time, immediately before the sandwiching of the continuous pouch body 1 is released, the chuck 47e is in the closed state and holds the cut end of the continuous pouch body 1. Note that the clamps 32b and 35 reach the top dead center at the phase angle of 170 ° after starting to rise at the phase angle of 155 °.

When the phase angle reaches 170 °, the drive shaft 45 starts sliding in the direction of arrow A. Then, the chuck head 47, the release head 53, and the release shaft 54 move integrally with the drive shaft 45, and the continuous pouch 1 held by the chuck 47e of the chuck head 47 is conveyed in the direction of arrow A.

When the continuous pouch 1 is conveyed in the direction of arrow A and the seal portion 3 of the continuous pouch 1 is supplied to the suction pads 13 and 14, at least one of the suction pads 13 and 14 and the continuous pouch 1 are connected. Is removed, 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 seam detection circuit 2
A seal portion detection signal is output from 5.

When the seal portion detection signal is output from the seam detection circuit 25, the electromagnetic switch 55 is energized via the drive circuit 55a, and the plunger 55 of the electromagnetic solenoid 55 is energized.
b pulls in the direction of arrow A. Then, as the lever 56 rotates, the pin 56b of the lever 56 is pressed against the release shaft 54, so that the slide of the release shaft 54 is restrained, and the drive shaft 45 moves in the direction of arrow A with respect to the release head 53 and the release shaft 54. To slide.

When the drive shaft 45 slides with respect to the releasing head 53 and the releasing shaft 54, the releasing portion 53a of the releasing head 53 enters into the accommodating portion 47a of the chuck head 47, and the pin 47b of the chuck head 47 is moved in the opposite arrow A direction. Press and move in the direction. Then, the pin 47b is separated from the outer peripheral surface of the drive shaft 45 and the inner surface of the accommodating portion 47a, so that the chuck head 47 is disengaged from the drive shaft 45 and the chuck head 47 stops moving. As a result, the transport operation of the continuous pouch 1 is stopped, and the seal portion 3 is supplied between the lower blade 31a and the upper blade 31b. The constant feed amount in FIG. 26 corresponds to the movement amount (a + b) of the chuck head 47.

After that, 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 4
After 5 moves to the maximum feed position and one cycle is completed, the above series of operations is repeated. The belt conveyor below the push rod 39 and the push rod 39
In order to synchronize with the lowering operation of (1) and to surely insert the pouch into the container, when the drive shaft 45 moves to the maximum feed position, the motor 27 is once turned off and then turned on again. .

According to the above embodiment, the chuck head 47
The drive shaft 45 and the chuck head 47 were disconnected from each other along with the movement of the pin 47b, and the conveyance amount of the continuous pouch 1 was controlled. Therefore, expensive electric means such as a movement amount measuring means and a control device are not required, and the cost of the apparatus is reduced.

Further, the chuck head 47 is moved by the distance "a + b" (dimension from the cutting means 31 to the boundary of the seal portion 3 + dimension from the boundary of the seal portion 3 to the central portion) in accordance with the output of the seam detection signal. After that, the chuck head 47
The drive shaft 45 and the drive shaft 45 are disconnected from each other, and the transport operation of the continuous pouch 1 is stopped. Therefore, even if the length of the accommodating portion 2 along the direction of the arrow A varies, the working position of the seal portion 3 (a fixed position away from the boundary of the seal portion 3 by a distance b) is set to the lower blade 31a and the upper blade 31a. It can be reliably supplied to the blade 31b. At the same time, the transport stop timing of the continuous pouch body 1 is determined from the movement amount of the chuck head 47, so that it is not affected by the variation in the transport speed of the continuous pouch body 1 due to the uneven rotation of the motor 27 and the like. The working position can be reliably supplied to the lower blade 31a and the upper blade 31b.

Further, since the initial position (conveyance amount) of the chuck head 47 can be adjusted by the conveyance amount adjusting member 57, for example, the type of the continuous pouch 1 is changed and the length dimensions of the accommodating portion 2 and the seal portion 3 are changed. Even if there is an error in manufacturing or the device has a manufacturing error, the center portion of the seal portion 3 can be reliably supplied to the lower blade 31a and the upper blade 31b by correcting the dimensional change and the error. At the same time, the carrying amount of the continuous pouch body 1 can be easily adjusted even during the pouch loading operation, so that it is not necessary to interrupt the work and adjust the carrying amount.

When the drive shaft 45 was slid in the direction opposite to the arrow A, the chuck head 47 was brought into contact with the push-back rod 46a. For this reason, the return timing of the chuck head 47 is delayed, so that it is possible to prevent the chuck head 47 from interfering with the push rod 39 and hindering the operation of dropping the pouch.

By the way, in detecting the seal portion 3 of the continuous pouch 1, the structures shown in the following (1) and (2) have been used. (1) The continuous pouch body 1 is sandwiched by a pair of movable rollers, and the seal portion 3 is detected from the moving amount of the roller along the thickness direction of the continuous pouch body 1. (2) The registration mark printed on the sticker portion 3 is read by the photoelectric sensor.

However, in the case of the continuous pouch 1 in which the step between the accommodating portion 2 and the seal portion 3 is unclear, the amount of roller movement becomes extremely small in the device (1), and the seal portion 3 is accurately I can't tell. At the same time, in the case of the device of (1), there is a risk that the contents such as fragrance will be pressed and cracked.
Further, in the device (2), it is necessary to print the registration mark in advance. At the same time, characters or the like printed on the continuous pouch 1 are erroneously determined as a registration mark, or there is no color difference between the registration mark and the continuous pouch 1,
The registration mark may not be detected.

On the other hand, in the above embodiment, the seal portion 3 is detected in accordance with the determination of the suction state of the continuous pouch 1 by the suction pads 13c and 14c based on the output signals from the pressure switches 21 and 22. . For this reason,
Unlike the configuration of (2), the trouble of printing the registration mark in advance is eliminated. At the same time, the characters printed on the continuous pouch 1 are not erroneously determined as the registration mark, and the registration mark is not detected. Moreover, unlike the configuration of (1), the seal portion 3 can be accurately discriminated even when the step between the housing portion 2 and the seal portion 3 is unclear. At the same time, the problem that the contents such as shattering are pressed and cracked is eliminated, and the seal portion 3 is surely detected as a whole.

Further, the vacuum generator 17 and the intake passage 1
9, the suction force is applied to the continuous pouch body 1 from the suction pad 13c, and the suction force is applied to the continuous pouch body 1 from the suction pad 14c using the vacuum generator 18 and the intake passage 20. Therefore, since the intake passages 19 and 20 can be shortened, the responsiveness becomes faster, and as a result, the seam detection operation becomes faster.

Further, the suction heads 13 and 14 are provided so as to be movable up and down, and the tension coil springs 15 urge the heads toward each other. Therefore, the continuous pouch 1 is the tension coil spring 1
As the suction pads 13c and 14c are pressed against the spring force of 5, the suction pads 13c and 14c move up and down following the shape of the continuous pouch body 1, so that the seal portion 3 is stable without error. To be detected.

Further, the suction heads 13 and 14 were suspended by the tension coil spring 16. For this reason, even if the continuous pouch 1 moves up and down during conveyance or the conveyance position of the continuous pouch 1 shifts in the vertical direction due to an error in the conveyance mechanism, the tension coil spring 16 expands and contracts to absorb the vertical movement. Also from this point, the seal portion 3 can be detected stably without any mistake.

Further, the stoppers 24a and 24b restrict the approach of the suction pads 13c and 14c, and in the approach restricted state, a gap larger than the thickness dimension of the seal portion 3 is formed between the suction pads 13c and 14c. For this reason, when the seal portion 3 is supplied to the suction pads 13c and 14c, at least one of the suction pads 13c and 14c is reliably separated from the continuous pouch body 1, and the seal portion 3 is stable without any mistake from this point as well. Detected.

Further, the continuous pouch 1 is guided to the suction surface of the suction pad 13c and the suction surface of the suction pad 14c by the entanglement preventing projections 13e and 14e of the suction heads 13 and 14. Therefore, as shown in FIG. 61, it is possible to prevent the continuous pouch body 1 from winding the suction pads 13c and 14c, and from this point as well, the seal portion 3 is stably detected without error.

Further, since the suction pads 13c and 14c are brought into contact with the expansion preventing wall portions 13g and 14g, the expansion of the suction pads 13c and 14c is limited.
Therefore, as shown in FIG. 60, it is possible to prevent the suction amount by one of the suction pads 13c and 14c from becoming excessively large and the other from being largely separated from the continuous pouch body 1, and from this point as well, 3 is stably detected without mistake.

By the way, in carrying the continuous pouch 1, the structures described in (1) and (2) below were used. (1) The continuous pouch body 1 is sandwiched by a pair of rollers, and the continuous pouch body 1 is sent out as the rollers rotate. (2) A feed plate is attached to the piston rod of the air cylinder, and the accommodating portion 2 and the seal portion 3 are attached as the piston rod protrudes.
The feed plate is engaged with the step between and, and the continuous pouch 1 is pressed and moved by the feed plate.

However, in the configurations of (1) and (2), as shown in (a) of FIG. 63, the roller and the air cylinder are arranged on the side opposite to the arrow A of the cutting means 4, and the continuous pouch 1 is attached. It was extruded in the direction of arrow A and supplied to the cutting means 4. Therefore, when the particularly soft continuous pouch 1 is extruded, the continuous pouch 1 may be bent and the actual transport amount may deviate from the set amount. As described above, if the transport amount is deviated, the accommodation portion 2 of the continuous pouch 1 may be erroneously cut.

The continuous pouch 1 is stored in a state of being folded in a meandering shape or wound in a roll. Therefore, when the continuous pouch body 1 is extruded after cutting the seal portion 3, as shown in FIG. 63 (b), the seal portion 3 having a round bending tendency interferes with the cutting means 4 during storage, and the continuous cutting is continued. The pouch 1 cannot be transported smoothly.

On the other hand, in this embodiment, the chuck 47e is provided on the lower blade 31a and the upper blade 31b on the arrow A direction side, and the chuck 47e moves the chuck 47e in the arrow A direction.
Along with the movement in the direction, the continuous pouch 1 was pulled and new seal portions 3 were supplied to the lower blade 31a and the upper blade 31b. For this reason, the cut end of the seal portion 3 having a bending tendency can be grasped and pulled, so that the cut end of the seal portion 3 is prevented from interfering with the lower blade 31a or the upper blade 31b. At the same time, since the continuous pouch 1 is prevented from being bent during the transportation, the continuous pouch 1 can be generally transported by the set amount and reliably supplied to the lower blade 31a and the upper blade 31b.

When cutting the seal portion 3,
The seal portion 3 was held by the mounting plate 32a and the clamp 32b. Therefore, the seal portion 3 is reliably cut without floating. Especially when the content is light or thin, the continuous pouch body 1 may rise due to the bending tendency of the seal portion 3 and the continuous pouch body 1 may be displaced, so that the cutting position is conventionally the seal portion. Sometimes it was out of 3. On the other hand, in this embodiment, the seal portion 3 is sandwiched. Therefore, since the bending tendency can be pressed and corrected, the continuous pouch body 1 is reliably cut from the seal portion 3. At the same time, when the seal portion 3 was cut and the continuous pouch 1 was conveyed, the seal portion 3 was opened by the mounting plate 32a and the clamp 32b. Therefore, the continuous pouch 1 can be transported without any trouble.

Further, the cut end of the seal part 3 was held by the chuck 47e while the cut end of the seal part 3 was fixed between the mounting plate 32a and the clamp 32b. Therefore, the cut end portion is reliably gripped without being influenced by the bending tendency, so that the continuous pouch 1 can be reliably transported.

Along with the movement of the mounting plate 32a and the clamp 32b, a gap is formed between the lower blade 31a and the cut end of the seal portion 3, and between the upper blade 31b and the cut end of the seal portion 3. Was formed. Therefore, the chuck 47e can grip the cut end portion of the seal portion 3 through this gap, so that the chuck 47e is prevented from interfering with the lower blade 31a and the upper blade 31b.

Further, the chuck 47e is configured to hold the cut end of the seal portion 3 through the clamp 32b. Therefore, the gripping amount of the cut end portion by the chuck 47e increases, so that it is possible to prevent the continuous pouch body 1 from coming off the chuck 47e as the chuck 47e moves. Along with this, even when the cut end of the continuous pouch 1 is gripped in a clamped state, the cut end is reliably gripped. Further, since the comb-shaped claw-shaped chuck 47e is used, even if oil or the like is attached to the surface of the continuous pouch body 1, the continuous pouch body 1 can be reliably pulled without slipping.

Since the contact type seam (seal part) detecting means using the suction pads 13c and 14c and the pull-out type conveying means using the chuck 47e are combined, the seam detecting means and the lower blade 31a and the upper blade are combined. It is not necessary to provide a transporting means such as a roller between 31b. For this reason, since the suction pads 13c and 14c can be arranged close to the lower blade 31a and the upper blade 31b, the device can be downsized.

Next, a second embodiment of the present invention will be described with reference to FIGS. 27 and 28. The same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. Hereinafter, only different members will be described. First, FIG.
In the suction heads 13 and 14, suction pads 13c and 14c are vertically movably housed.

The joint detection circuit 25 includes a drive circuit 59a.
And 60a via electromagnetic solenoids 59b and 60
b is connected, and the suction pads 13c and 14c are connected to the electromagnetic solenoids 59b and 60b through the crank mechanisms 59c and 60c. Incidentally, reference numeral 59
Indicates a moving means including a drive circuit 59a, an electromagnetic solenoid 59b, and a crank mechanism 59c. Reference numeral 6
Reference numeral 0 indicates a moving means including a drive circuit 60a, an electromagnetic solenoid 60b, and a crank mechanism 60c.

According to the above-described embodiment, when the suction pads 13c and 14c suck the housing portion 2, the seam detection circuit 2
An accommodation section detection signal is output from 5. Then, the drive circuits 59a and 60a move to the electromagnetic solenoids 59b and 60a.
Energize b. Then, the crank mechanisms 59c and 6
0c is activated, and as shown in FIG. 28, the suction pad 13c
And 14c move to the separated position away from the continuous pouch body 1 while adsorbing the continuous pouch body 1.

Therefore, the seal portion 3 is supplied to the suction pads 13c and 14c while the suction pads 13c and 14c are kept away from the continuous pouch body 1. Therefore, FIG.
2, the suction pads 13c and 14c are prevented from remaining in the state of adsorbing the continuous pouch body 1,
As shown in FIG. 28, the suction of the continuous pouch 1 by the suction pads 13c and 14c is reliably released.

When the suction of the continuous pouch 1 by the suction pads 13c and 14c is released, the seam detection circuit 25 outputs a seam detection signal. Then, the drive circuit 59
Since a and 60a release the electromagnetic solenoids 59b and 60b, the crank mechanisms 59c and 60c are actuated, and the suction pad 13 is moved to the approach position close to the continuous pouch body 1.
c and 14c move. Therefore, the suction pad 13c
Since the next housing portion 2 is surely adsorbed by and 14c, the seal portion 3 is generally detected stably without any mistake.

In the second embodiment, the suction pads 13c and 14c are moved up and down by the moving means 59 and 60 mainly composed of the electromagnetic solenoids 59b and 60b, but the invention is not limited to this. The suction pad 13c includes a moving means mainly composed of a motor, a moving means mainly composed of a cylinder, and a moving means mainly composed of a magnet.
And 14c may be moved up and down.

In the second embodiment, both the suction pads 13c and 14c are moved with respect to the suction heads 13 and 14, but the suction pads 13c or 1
4c may be moved with respect to the suction head 13 or 14.

Further, in the above-mentioned first and second embodiments, the pressure switches 21 and 22 which are turned on / off according to the pressure level in the intake passages 19 and 20 are provided.
For example, the intake passage 19 is not limited to this.
A pressure sensor that detects the pressure value in 20 and 20 and outputs an analog signal may be provided. In this case, it is advisable to detect that the negative pressure in the intake passages 19 and 20 has changed to the positive pressure side based on the comparison of 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. The same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. Hereinafter, only different members will be described.

The suction force of the vacuum generator 17 is set smaller than that of the vacuum generator 18, and the suction pad 13 on the lower side is set.
The suction force of c is smaller than the suction force of the upper suction pad 14c. Therefore, the continuous pouch 1 is conveyed while being always adsorbed by the adsorption pad 14c. Also,
The pressure switch 22 corresponding to the intake passage 20 is abolished, and the seam detection circuit 61 determines the seal portion 3 based on the output signal from the pressure switch 21.

According to the above embodiment, when the accommodation portion 2 of the continuous pouch 1 is supplied to the suction pads 13c and 14c,
The suction pad 13c adsorbs the housing portion 2. Then, the negative pressure in the intake passage 19 increases, and the pressure switch 21 is turned off, so that the joint detection circuit 61 outputs the accommodation portion detection signal.

When the seal portion 3 of the continuous pouch 1 is supplied to the suction pads 13c and 14c, the suction between the lower suction pad 13c and the continuous pouch 1 is released. Then, the negative pressure in the intake path 19 changes to the positive pressure side, and the pressure switch 21 is turned on, so that the seam detection circuit 61 outputs a seal portion detection signal. Therefore, the pressure switch 2
2 is eliminated and the circuit configuration of the joint detection circuit 61 is simplified, so that the cost of the device is reduced.

In the third embodiment, the vacuum generators 17 and 18 having different suction forces are used to make the suction force of the suction pad 13c smaller than the suction force of the suction pad 14c, but the present invention is not limited to this. However, for example, the suction area of the suction pad 13c is made smaller than the suction area of the suction pad 14c, or the ventilation resistance of the intake passage 19 corresponding to the suction pad 13c is changed to that of the suction passage 20 corresponding to the suction pad 14c. It may be larger than the ventilation resistance.

In particular, when the suction areas of the suction pads 13c and 14c are made different, if the suction force is applied to the suction pads 13c and 14c from one vacuum generator through a common intake passage, the cost of the apparatus will be further reduced. To be done. Further, a belt conveyor type suction body may be used instead of the suction pad 14c having a large suction force. This adsorbent is formed by forming a plurality of adsorption holes on a belt conveyor, and the continuous pouch body 1 is always adsorbed on the belt conveyor by sucking air through the plurality of adsorption holes while rotating the belt conveyor. Carry while carrying. Therefore, the suction pad 14c can be eliminated, and the members related to the suction pad 14c are also eliminated. In addition, in the case of this configuration, it is preferable to use the configuration of a twelfth or thirteenth embodiment described later when driving the belt conveyor.

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, and is connected to the seam detection circuit 65.

According to the above embodiment, when the accommodation portion 2 of the continuous pouch 1 is supplied to the suction pads 13c and 14c,
The suction pads 13c and 14c adsorb the housing portion 2.
Then, since the negative pressure in the intake pipe 63a increases, the pressure switch 64 is turned off, and the joint detection circuit 65 outputs the accommodating portion detection signal.

When the seal portion 3 is supplied to the suction pads 13c and 14c, the suction pads 13c and 14c are supplied.
Adsorption by at least one of c 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 circuit 65 outputs a seam detection signal. Therefore, one pressure switch 64 can be used, and the circuit configuration of the joint detection circuit 65 can be simplified, so that the cost of the device can be reduced.

Although the suction pads 13c and 14c are fixed to the suction heads 13 and 14 in the fourth embodiment, the invention is not limited to this. For example, as in the third embodiment, an electromagnetic solenoid is used. And the suction pad 13 by a moving means mainly composed of a motor, a cylinder, a magnet and the like.

Therefore, while the suction pads 13c and 14c are kept away from the continuous pouch body 1, the seal portion 3 has the suction pads 13c and 14c.
To the suction pads 13c and 14c, the suction by the suction pads 13c and 14c is reliably 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 force of the compression coil spring 66 causes the suction pads 13c and 14c to project,
The continuous pouch 1 is approached. For this reason, the next housing portion 2 is surely adsorbed, so that the seal portion 3 is generally detected stably without any mistake.

Next, a sixth embodiment of the present invention will be described with reference to FIG. The same members as those in the fifth embodiment are denoted by the same reference numerals, and description thereof will be omitted. Hereinafter, only different members will be described.

Further, reference numeral 68b indicates a wrap-around prevention projection formed on the support head 68. Further, reference numeral 68c indicates an expansion preventing wall portion formed on the support head 68.

According to the above embodiment, as in the fifth embodiment,
Since the suction pads 13c and 14c move according to the suction and release of the suction of the continuous pouch body 1, the seal portion 3 can be detected reliably and stably. Moreover, since the support head 68 can be mounted on the suction heads 13 and 14 after mounting the suction pads 13c and 14c on the support head 68, the mounting workability of the suction pads 13c and 14c is improved.
Further, since the inner volumes of the pad accommodating portions 13b and 14b are increased, the suction pad 1 is sucked as the continuous pouch 1 is sucked.
3c and 14c are pulled with a strong force. Therefore, the suction pads 13c and 14c are surely moved in the direction away from the continuous pouch body 1.

It may be configured to be biased by 66. In the case of this configuration, since the suction pad 13c or 14c moves according to the pressure in the intake pipe 63a, the seal portion 3 can be detected reliably and stably.

Next, a seventh embodiment of the present invention will be described with reference to FIG. The same members as those in the fifth embodiment are denoted by the same reference numerals, and description thereof will be omitted. Hereinafter, only different members will be described. A bellows portion 14i is formed integrally with the suction pad 14c.
i is housed in the pad housing portion 14b of the suction head 14 and is fixed to the upper wall of the pad housing portion 14b.

Since c moves, the seal portion 3 can be detected reliably and stably. Moreover, since the bellows portions 13i and 14i are formed integrally with the suction pads 13c and 14c,
The number of parts is reduced as compared with the case where the suction pads 13c and 14c are moved by the separate compression coil spring 66.

By the way, in the second embodiment, the air in the suction pad 13c is sucked by the vacuum generator 17 and the suction passage 19, and the air in the suction pad 14c is sucked by the vacuum generator 18 and the suction passage 20. For convenience, when the suction timing is deviated between the suction pads 13c and 14c, the negative pressure increase timing in the intake passages 19 and 20 is also deviated.

Therefore, as in the fifth to seventh embodiments,
The suction pads 13c and 14 immediately increase as the negative pressure increases.
When c is moved away from the continuous pouch 1 (when it is moved away by the compression coil spring or the bellows portion), one of the suction pads 13c and 14c sucks the continuous pouch 1 and moves, and the other moves far away from the continuous pouch 1. Housing 2
Can not be adsorbed. On the other hand, in the second embodiment, the suction pads 13c and 14c are moved away from the continuous pouch 1 after the housing detection signal is output from the seam detection circuit 25.

For example, a drive shaft having a polygonal cross section or a drive shaft having a D cut portion is used, and the pin 47b is brought into contact with the flat surface portion of the drive shaft. You may let me. In the case of this configuration, the contact area between the drive shaft and the pin 47b increases, so that the chuck head 47 is reliably prevented from sliding on 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. The same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. Hereinafter, only different members will be described. First, FIG.
At the chuck head 47, the drive shaft 4
5 is slidably inserted, the drive shaft 45 is provided with a disk-shaped stopper 45a located at the end portion in the direction of arrow A and corresponding to the push-back head, and is positioned in the direction opposite to the arrow A of the stopper 45a. Forming a semi-circular first concave portion 45b.

The chuck head 47 has an accommodating portion 4 which is open to the drive shaft 45 side and the release shaft 54 side.
7 g are formed. The accommodating portion 47g has a long hole shape with a circular cross section, and a cylindrical pin 47h is accommodated in the accommodating portion 47g. The chuck head 47 is connected to the drive shaft 45 as the pin 47h is engaged in the recess 45b of the drive shaft 45. In addition, pin 47h
Corresponds to the connecting means.

The release shaft 54 is provided with a disk-shaped stopper 54a located at the end portion in the direction of arrow A, and a second recess 54b having a semi-arcuate shape located in the direction opposite to the arrow A of the stopper 54a. Has been formed. Then, as shown in FIG. 37, in the state where the drive shaft 45 has moved in the direction opposite to the arrow A by the maximum amount and the end portion of the release shaft 54 in the direction opposite the arrow A is in contact with the stopper portion 57b of the conveyance amount adjusting member 57, Distance between stoppers 45a and 54a, recess 4
The distance between the center of 5b and the center of 54b is set to be "a + b". The inner surface of the first recess 45b and the inner surface of the second recess correspond to inclined surfaces, as will be apparent from the description below. Further, in the case of this 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 in the direction of arrow A from the maximum return position, the drive shaft 4
5 is transmitted to the chuck head 47 via the pin 47h, and the chuck head 47 moves the drive shaft 45.
Move together with. Thereby, the chuck head 47
The continuous pouch 1 gripped by the chuck 47e is conveyed in the arrow A direction. At the same time, due to the frictional force between the release shaft 54 and the chuck head 47, the release shaft 5
4 moves integrally with the chuck head 47 and the drive shaft 45.

After that, when the seal portion 3 of the continuous pouch 1 is supplied to the suction nozzles 13c and 14c and the joint detection signal is output from the joint detection circuit 25, the release shaft 54 of the release shaft 54 is energized as the electromagnetic switch 55 is energized. The movement is restricted, and the chuck head 47 and the drive shaft 45 move in the arrow A direction with respect to the release shaft 54. And
When the amount of movement reaches "a + b", the chuck head 47 contacts the stopper 54a of the release shaft 54, as shown in FIG.

At the same time, the pin 47h engaged in the recess 45b of the drive shaft 45 faces the recess 54b of the release shaft 54. When the drive shaft 45 moves in the direction of arrow A from this state, the drive shaft 45
The pin 47h is pressed against the inner surface of the concave portion 45b of
It is extruded to the release shaft 54 side along 7g. Then, the pin 47h is transferred from the recess 45b of the drive shaft 45 to the recess 54b of the release shaft 54, and the connection between the drive shaft 45 and the chuck head 47 is released. Thereby, the conveyance of the continuous pouch 1 is stopped, and the central portion of the seal portion 3 is supplied to the lower blade 31a and the upper blade 31b.

After that, as shown in FIG. 35, when the drive shaft 45 moves in the direction of the arrow A by the maximum amount and starts to move in the direction of the opposite arrow A, the release shaft 54 is restrained due to the disconnection of the electromagnetic switch 55. It will be canceled. Then, when a slight slip occurs between the drive shaft 45 and the chuck head 47, the stopper 45a of the drive shaft 45 contacts the chuck head 47, and while maintaining the state shown in FIG. 36, the drive shaft 45, The chuck head 47 and the release shaft 54 slide in the opposite arrow A direction.

Drive shaft 45, chuck head 4
7. The release shaft 54 slides in the direction opposite to the arrow A, and the release shaft 54 stops the stopper portion 57 of the conveyance amount adjusting member 57.
When it comes into contact with b, the movement of the release shaft 54 is restricted,
The drive shaft 45 and the chuck head 47 slide in the direction opposite to the arrow A with respect to the release shaft 54. Then, the release shaft 54 is pressed against the inner surface of the recess 54b,
The pin 47h moves along the accommodating portion 47g and the drive shaft 4
5 is extruded to the concave portion 45b side. This allows pin 47
h is transferred from the recess 54b of the release shaft 54 to the recess 45b of the drive shaft 45.

After this, the opposite arrow A of the drive shaft 45
When the movement in the direction is stopped, as shown in FIG. 37, between the stoppers 45a and 54a and between the recesses 45b and 54b.
It returns to the initial state in which the distance is "a + b". Then, the series of operations described above is repeated.

By the way, in the first embodiment, as shown in FIGS. 9 to 11, as the pin 47b is pressed against the inner surface of the accommodating portion 47a and the outer peripheral surface of the drive shaft 45, the drive shaft 45 and the chuck are contacted. Head 4
7 and the pin 47b is pushed by the release portion 53a of the release head 53, the drive shaft 4
5 was cut off from the chuck head 47.

Therefore, when the connection and disconnection between the drive shaft 45 and the chuck head 47 are repeatedly performed, the outer peripheral surface of the drive shaft 45, the inner surface of the accommodating portion 47a, and the outer peripheral surface of the pin 47b are abraded, resulting in sufficient connection. There is a risk that power will not be obtained. Therefore, it is necessary to frequently check the wear state of each member and stop the production line to replace the worn parts when the wear is found. On the contrary,
A mass production device such as a pouch insertion device is required to be capable of continuous operation for a long time with less maintenance. In order to improve this, it is conceivable to quench the worn portion or form the worn portion from a hard member such as ceramic, but this increases the cost.

In this respect, in the eighth embodiment, the pin 47h is provided between the drive shaft 45 and the release shaft 54.
The drive shaft 45 and the chuck head 47 are connected and cut off upon delivery. Therefore, the frictional force acting on the drive shaft 45, the chuck head 47, and the pin 47h is reduced as much as possible, so that the durability of the drive shaft 45, the chuck head 47, and the pin 47h is improved. Therefore, the labor of checking the wear state of each member and the labor of replacing the worn parts by stopping the production line can be reduced at the lowest cost.

Next, a ninth embodiment of the present invention will be described with reference to FIGS. 38 to 40. The same members as those in the eighth embodiment will be designated by the same reference numerals and description thereof will be omitted, and only different members will be described below. First, FIG.
In the above, the release shaft 54 is provided with an L-shaped stopper 54c located at the end portion in the direction of arrow A, and a disk-shaped stopper 54d located on the opposite side of the stopper 54c in the direction of arrow A. .

A compression coil spring 54e is inserted between the stopper 54c and the chuck head 47 on the outer peripheral portion of the release shaft 54. The compression coil spring 54e moves the stopper 54c of the release shaft 54 in the direction of arrow A. The stopper 54d of the release shaft 54 is brought into contact with the chuck head 47 as it is urged toward.
Then, in this state, the stopper 5 of the release shaft 54
The distance between 4c and the stopper 45a of the drive shaft 45 is set to "a + b".

Next, the operation of the above configuration will be described. When the drive shaft 45 moves in the direction of arrow A from the maximum return position, the chuck head 47 moves the drive shaft 45.
Move together with. Along with this, the chuck head 47
Presses the stopper 54c via the compression coil spring 54e, so that the release shaft 54 moves integrally with the chuck head 47 and the drive shaft 45. No frictional force (frictional force of the eighth embodiment) for engaging the releasing shaft 54 and the chuck head 47 with each other is applied.

Thereafter, when the seal portion 3 of the continuous pouch 1 is supplied to the suction nozzles 13c and 14c and the joint detection signal is output from the joint detection circuit 25, the movement of the release shaft 54 is restricted. Then, the chuck head 47
Presses the compression coil spring 54e, and the compression coil spring 54e
Since e contracts, the chuck head 47 and the drive shaft 45 move in the direction of arrow A with respect to the release shaft 54.

When the amount of movement reaches (a + b), the chuck head 47 contacts the stopper 54c of the release shaft 54, as shown in FIG. At the same time, the pin 47h faces the recess 54b of the release shaft 54. Then, when the drive shaft 45 further moves in the direction of arrow A, the pin 47h is transferred from the recess 45b of the drive shaft 45 to the recess 54b of the release shaft 54.
5, the chuck head 47 and the release shaft 54 are connected to each other. As a result, the continuous pouch 1
Is stopped, and the central portion of the seal portion 3 is supplied to the lower blade 31a and the upper blade 31b.

After this, as shown in FIG. 40, when the drive shaft 45 moves in the direction of arrow A by the maximum amount and starts to move in the direction of the opposite arrow A, the release shaft 54 is restrained due to the disconnection of the electromagnetic switch 55. It will be canceled. Then, due to slippage between the drive shaft 45 and the chuck head 47, the drive shaft 45 moves in the direction opposite to the arrow A with respect to the chuck head 47. And FIG.
As shown in, the stopper 45 of the drive shaft 45
a comes into contact with the chuck head 47, and the concave portion 45b has the pin 4
Face 7h.

Then, the restoring force of the compression coil spring 54e pushes the stopper 54c of the release shaft 54 in the direction of arrow A, and the stopper 54d of the release shaft 54 contacts the chuck head 47. Thereby, the recess 45
b and 54b and stoppers 45a and 54c are separated by "a + b", and the initial state is restored. At the same time, the pin 47h is transferred from the recess 54b of the release shaft 54 to the recess 45b of the drive shaft 45, and the chuck head 47 is connected to the drive shaft 45.

Drive shaft 45, chuck head 4
7. When the release shaft 54 returns to the initial state, the kinetic force of the drive shaft 45 in the direction opposite to the arrow A becomes the pin 47h.
And is transmitted to the chuck head 47 via the stopper 45a. At the same time, the moving force of the chuck head 47 is transmitted to the release shaft 54 via the stopper 54d. As a result, the chuck head 47 and the release shaft 54 move integrally with the drive shaft 45, and
It returns to the state shown in. Then, the series of operations described above is repeated.

According to the above-described embodiment, the stopper 54c of the release shaft 54 is pressed by the compression coil spring 54e, and the stopper 54d of the release shaft 54 is brought into contact with the chuck head 47.
5. The chuck head 47 and the release shaft 54 were returned to the initial state. Therefore, unlike the case where the distal end portion of the release shaft 54 is in contact with the stopper portion 57b of the transport amount adjusting member 57, abrasion of the distal end portion of the release shaft 54 is prevented. Moreover, since it is not necessary to apply a frictional force between the chuck head 47 and the release shaft 54,
Wear of the outer peripheral surfaces of both is reduced.

Next, a tenth embodiment of the present invention will be described with reference to FIGS. 41 to 43. The same members as those in the ninth embodiment are denoted by the same reference numerals, and description thereof will be omitted. Hereinafter, only different members will be described.

And the distance between the concave portion 45b and the concave portion 54b is held at "a + b".

Next, the operation of the above configuration will be described. When the drive shaft 45 moves in the direction of arrow A from the maximum return position, the chuck head 47 moves the compression coil spring 54e.
Since the stopper 54c is pressed via the release shaft 54, the release shaft 54 is moved to the chuck head 47 and the drive shaft 4.
Moves together with 5. After that, when the seam detection signal is output from the seam detection circuit 25, the movement of the release shaft 54 is restricted. Then, the chuck head 47 presses the compression coil spring 54e and the compression coil spring 54e contracts, so that the drive shaft 45 and the chuck head 47 move in the arrow A direction with respect to the release shaft 54.

When the amount of movement reaches (a + b), the chuck head 47 contacts the stopper 54c of the release shaft 54, and the amount of movement becomes "a", as shown in FIG.
+ B ”is exceeded, the pin 47h becomes the drive shaft 45.
The concave portion 45b of the release shaft 54 is delivered to the concave portion 54b of the release shaft 54. As a result, the chuck head 47 and the drive shaft 45 are disconnected from each other, and the chuck head 47 and the release shaft 54 are connected to each other.

After this, as shown in FIG. 43, when the drive shaft 45 starts moving in the direction opposite to the arrow A, the restraint of the release shaft 54 is released. Then, due to slippage between the drive shaft 45 and the chuck head 47, the drive shaft 45 moves in the direction opposite to the arrow A with respect to the chuck head 47. Then, as shown in FIG. 42, the stopper 45a of the drive shaft 45 contacts the chuck head 47, and the recess 45b faces the pin 47h.

Then, the compression coil spring 54e presses the stopper 54c of the release shaft 54 in the direction of arrow A, and the stopper 54c contacts the stopper 47i. This restores the initial state in which the recesses 45b and 54b and the stoppers 45a and 54c are separated by "a + b". At the same time, the pin 47h is transferred from the recess 54b of the release shaft 54 to the recess 45b of the drive shaft 45, and the chuck head 47 is connected to the drive shaft 45.

And is transmitted to the chuck head 47 via the stopper 45a. At the same time, the moving force of the chuck head 47 is transmitted to the stopper 54c of the release shaft 54 via the stopper 47i. As a result, the chuck head 47 and the release shaft 54 move integrally with the drive shaft 45, and the state shown in FIG. 41 is restored. Then, the series of operations described above is repeated.

According to the above embodiment, the stopper 54c of the release shaft 54 is brought into contact with the stopper 47i so that the drive shaft 45, the chuck head 47,

The distance between the recess 45b and the recess 54b and the stoppers 45d and 54c is kept at "a + b".

Next, the operation of the above configuration will be described. When the drive shaft 45 moves in the direction of arrow A from the maximum return position, the chuck head 47 moves the compression coil spring 54e.
Since the stopper 54c is pressed via the release shaft 54, the release shaft 54 is moved to the chuck head 47 and the drive shaft 4.

Thereafter, as shown in FIG. 46, when the drive shaft 45 starts moving in the direction opposite to the arrow A, the restraint of the release shaft 54 is released. Then, due to slippage between the drive shaft 45 and the chuck head 47, the drive shaft 45 moves in the direction opposite to the arrow A with respect to the chuck head 47. Then, as shown in FIG. 45, the stopper 45d of the drive shaft 45 contacts the chuck head 47, and the recess 45b faces the pin 47h.

Then, the compression coil spring 54e presses the stopper 54c of the release shaft 54 in the direction of arrow A, and the stopper 54c contacts the stopper 45c. This restores the initial state in which the recesses 45b and 54b and the stoppers 45d and 54c are separated by "a + b". At the same time, the pin 47h is transferred from the recess 54b of the release shaft 54 to the recess 45b of the drive shaft 45, and the chuck head 47 is connected to the drive shaft 45.

Drive shaft 45, chuck head 4
7. When the release shaft 54 returns to the initial state, the kinetic force of the drive shaft 45 in the direction opposite to the arrow A becomes the pin 47h.
And transmitted to the chuck head 47 via the stopper 45d. At the same time, the moving force of the drive shaft 45 is transmitted to the stopper 54c of the release shaft 54 via the stopper 45c. As a result, the chuck head 47 and the release shaft 54 move integrally with the drive shaft 45, and the state shown in FIG. 44 is restored. And
The above series of operations is repeated.

According to the above-described embodiment, when the stopper 54c of the release shaft 54 is brought into contact with the stopper 45c of the drive shaft 45, the drive shaft 4
5. The chuck head 47 and the release shaft 54 were returned to the initial state. Therefore, unlike the case where the distal end portion of the release shaft 54 is in contact with the stopper portion 57b of the transport amount adjusting member 57, abrasion of the distal end portion of the release shaft 54 is prevented. Moreover, since it is not necessary to apply a frictional force between the chuck head 47 and the release shaft 54, wear on the outer peripheral surfaces of both is reduced.

In the eighth to eleventh embodiments,
The columnar pin 47h is used to disconnect and connect the drive shaft 45 and the chuck head 47, but the pin 47h is not limited to this and may be, for example, a rectangular parallelepiped pin. In the case of this configuration, the housing portion 47

The output timing of the seal portion detection signal from 5 may be shifted. This configuration does not require expensive control means such as a microcomputer or sequencer or measuring means such as a sensor, and therefore has an advantage that the transport amount can be finely adjusted by a simple and inexpensive configuration.

In the first to eleventh embodiments, the clamp 32b is provided with the plurality of notches 32d and the comb-shaped chuck 47e is used (that is, both the clamp 32b and the chuck 47e are used). Although the notch is provided), the present invention is not limited to this. For example, the notch may be formed in one of the clamp 32b and the chuck 47e, and the other may be inserted into the notch.

In the first to eleventh embodiments, the pins 47b and 47h are used to disconnect and connect the drive shaft 45 and the chuck head 47e.
However, the present invention is not limited to this, and a ratchet mechanism may be used, for example. In addition, the above first to eleventh

In the eleventh embodiment, the comb tooth-shaped chuck 47e is used, but the invention is not limited to this, and a saw blade-shaped chuck may be used. Even in the case of this configuration, the continuous pouch 1 can be gripped by the chuck in a non-slip state.

In the first to eleventh embodiments, the drive circuit 55a turns off the electromagnetic switch 55 when a predetermined time has elapsed after the seam detection signal was output from the seam detection circuit 25. However, the timing sensor 58 is not limited to this, and the timing sensor 58 is not limited to the cam 29.
The inversion timing of the drive shaft 45 is detected from the convex portion of the cam surface of a, and the drive circuit 55a detects the timing sensor 5
Alternatively, the electromagnetic switch 55 may be turned off based on the detection signal from 8.

Next, a twelfth embodiment of the present invention will be described with reference to FIGS.
2 will be described. The same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.
Only different members will be described. First, in FIG. 47, a motor (not shown) corresponding to a drive source is connected to the rotating shaft 71 corresponding to the first moving means, and when the motor operates, the rotating shaft 71 rotates in the direction of arrow D. It is supposed to do.

On the outer peripheral surface of the rotating shaft 71, a gear-shaped rotating body 72 corresponding to the conveying means is inserted. The rotating body 72 has a tapered accommodating portion 73a that extends in a direction opposite to the arrow E and an arcuate portion 73e that is concentric with the rotating shaft 71.
Is formed, and the pin 73b corresponding to the connecting means is housed in the housing portion 73a. Incidentally, the accommodating portion 73a
Is connected to the arc portion 73e.

A mounting member 73c is mounted on the rotating body 72. Two compression coil springs 73d (see FIG. 48) are attached to the tip end of the attachment member 73c, and each of the springs 73d faces the pin 73b toward the narrow side (arrow E direction) of the accommodating portion 73a. Along with pressing
The pin 7 is provided on the inner surface of the accommodating portion 73a and the outer peripheral surface of the rotating shaft 71.
3b is pressed. As a result, the pin 73b is held in the connected state, the rotating body 72 is connected to the rotating shaft 71, and is rotated integrally with the rotating shaft 71 in the arrow D direction. Incidentally, reference numeral 73 is a housing portion 73a, a pin 73b,
The driving force transmitting means including the mounting member 73c and the compression coil spring 73d is shown.

A chain 74 is attached to the rotating body 72, and when the rotating body 72 rotates in the direction of arrow D in accordance with the operation of the motor, the chain 74 rotates and moves so that the continuous pouch 1 is conveyed. There is. Further, as shown in FIG. 48, a circular releasing body 76 is attached to the rotating body 72 via a torsion coil spring 75. The releasing body 76 corresponds to the second moving means, and when the restraining force does not act on the releasing body 76, the rotational force of the rotating body 72 is transmitted to the releasing body 76 via the spring 75. The releasing body 76 is adapted to rotate integrally with the rotating body 72. The motor is connected to a drive circuit (not shown), and this drive circuit intermittently rotates the motor by a constant amount.

As shown in FIG. 49, the releasing member 76 is formed with a convex releasing portion 76a corresponding to the releasing means. This releasing portion 76a is inside the arc portion 73e as shown in FIG. It is accommodated on the arrow E side. Therefore, in the state where the restraining force does not act on the releasing body 76 and the releasing body 76 rotates together with the rotating body 72 in the arrow D direction,
The releasing portion 76a of the releasing body 76 is held in the arc portion 73e on the arrow E direction side.

A pin 78c of a lever 78 is rotatably inserted in the base 77 shown in FIG. 50, as shown in FIG. Further, pins 77b and 78a are fixed to the base 77 and the lever 78, and a tension coil spring 79a is attached to the pins 77b and 78a.

As shown in FIG. 50, an electromagnetic switch 80 composed of an electromagnetic solenoid is fixed to the base 77. The electromagnetic switch 80 is connected to the seam detection circuit 25, and the plunger 80 of the electromagnetic switch 80 is connected.
A tension coil spring 79b is connected to a. Also,
As shown in FIG. 51, a pin 78b is fixed to the lever 78, and a tension coil spring 79b is connected to the pin 78b. Incidentally, reference numeral 81 indicates a restraint means including a lever 78 and an electromagnetic switch 80.

Next, the operation of the above configuration will be described. The accommodating portion 2 of the continuous pouch 1 has suction pads 13c and 14c.
The electromagnetic switch 80 is cut off in a state in which the storage section detection signal is output from the seam detection circuit 25 after passing through. Therefore, the plunger 80a of the electromagnetic switch 80 is
Is projected, and the lever 78 is held in a state of being separated from the releasing body 76. Therefore, since the restraining force does not act on the releasing body 76 from the lever 78, the rotating force of the motor is changed by the rotating shaft 71.
Is transmitted to the rotating body 72 through the pin 73b, and the chain 74 rotates. Thereby, the continuous pouch 1 is conveyed.

After that, when the seal portion 3 of the continuous pouch 1 is supplied to the suction pads 13c and 14c and the joint detection signal is output from the joint detection circuit 25, the electromagnetic switch 80 is energized. Then, the plunger 80a of the electromagnetic switch 80 is retracted against the spring force of the tension coil spring 79a, and the lever 78 is held in pressure contact with the release member 76, as shown in FIG. Therefore, a restraining force acts on the releasing body 76 from the lever 78, so that the rotation of the releasing body 76 is restrained.

When the rotation of the releasing body 76 is restricted, only the rotating body 72 rotates in the direction of arrow D against the spring force of the torsion coil spring 75. Then, when the pin 73b engaged with the inner surface of the accommodating portion 73a moves to the releasing portion 76a side of the releasing body 76 and comes into contact with the releasing portion 76a, the pin 73b has the wide side (counter arrow E in the accommodating portion 73a). Direction), and is moved to a blocked state in which it is separated from the inner surface of the housing portion 73a and the outer peripheral surface of the rotating shaft 71. As a result, the rotational force of the motor is not transmitted to the rotating body 72, and as a result, the chain 74 stops.

When the chain 74 stops rotating, the continuous pouch 1 is stopped from being conveyed, and the central portion of the seal portion 3 is supplied to the lower blade 31b and the upper blade 31a. Then, the clamp 32
After b holds the seal portion 3 of the continuous pouch body 1, the upper blade 31
a is lowered, and the continuous pouch 1 is cut from the seal portion 3. The moving distance of the pin 73b (dimension of the arc portion 73e)
Is preset so that the continuous pouch 1 is conveyed by (a + b) by the chain 74.

When the seal portion 3 is cut off, the motor and the electromagnetic switch 80 are cut off, and the spring force of the tension coil spring 79a causes the lever 78 to rotate about the pin 78c.
The initial state separated from the releasing body 76 is restored. Then
Since the restraint force from the lever 78 does not act on the releasing body 76, the releasing body 76 rotates with respect to the rotating body 72 by the restoring force of the torsion coil spring 75, and the releasing portion 76a of the releasing body 76 is released.
Returns to the initial state in which the abutting contact is made on the narrow side of the accommodating portion 73a. Then, as the motor operates, the above series of operations is repeated. The spring force of the tension coil spring 79b is set to be larger than the spring force of the tension coil spring 79a.

According to the above-described embodiment, the rotary shaft 71 and the rotary body 72 are disconnected and coupled with the movement of the pin 73b in the accommodating portion 73a to control the carrying amount of the continuous pouch body 1. Therefore, expensive electric means such as a movement amount measuring means and a control device are not required, and the cost of the apparatus is reduced.

In the eighth embodiment, the rotating body 7
The torsion coil spring 75 is used to connect the two and the releasing body 76, but the invention is not limited to this, and the structure may be connected by a frictional force, for example. In this configuration,
It is advisable to reverse the motor as the restraint of the releasing body 76 is released and to return the releasing portion 76a of the releasing body 76 to the initial position.

Next, a thirteenth embodiment of the present invention will be described with reference to FIGS.
5 will be described. The same members as those in the twelfth embodiment will be designated by the same reference numerals and description thereof will be omitted, and only different members will be described below. First, FIG.

6b, the pin 72 is inserted in the initial state.
“A” is located at the end of the accommodation portion 76b in the direction opposite to the arrow D.

The rotary shaft 71 is attached to the tubular portion 72b of the rotary body 72.
Side and the releasing body 76 side are formed with an accommodating portion 72c, and a cylindrical pin 72d corresponding to a connecting means is accommodated in the accommodating portion 72c. The rotary shaft 71 and the release member 76 have a first V-shaped first recess 7 formed therein.
1a and the second recess 76c are formed, and the pin 7
As 2d is engaged with the recess 71a of the rotary shaft 71, the rotary body 72 is connected to the rotary shaft 71. The inner surface of the first recess 71a and the inner surface of the second recess 76c correspond to inclined surfaces, as will be apparent from the description below.

Next, the operation of the above configuration will be described. When the restraining force does not act on the releasing body 76, the rotating force of the motor is transmitted from the rotating shaft 71 through the pin 72d to the rotating body 72.
The continuous pouch 1 is conveyed in the direction of arrow E as the chain 74 rotates. At the same time, the release body 76 is rotated in the direction of arrow D integrally with the rotating body 72 by transmitting the rotational force of the rotating body 72 via the torsion coil spring 75.

After that, when the seal portion 3 of the continuous pouch 1 is supplied to the suction pads 13c and 14c and the seal portion detection signal is output from the seam detection circuit 25, the electromagnetic switch 80 is energized and the release member 76 is released. The rotation is restricted. Then, the rotating shaft 71 and the rotating body 72 rotate in the direction of arrow D with respect to the releasing body 76, and the torsion coil spring 75 is twisted. Then, the rotating shaft 71 and the releasing body 76 for the rotating body 72
When the amount of rotation with respect to “a + b” reaches “a + b”, the pin 72a of the rotating body 72 causes the arrow D in the housing portion 76b of the releasing body 76 to move.
It contacts the inner surface on the direction side. The size of the housing portion 76b is
It is set in advance so that the moving distance of the pin 72a is required to move the continuous pouch 1 by "a + b".

At the same time, the pin 72d faces the recess 76b of the release member 76, and only the rotary shaft 71 rotates in the direction of arrow D. Then, the inner surface of the recess 71a of the rotating shaft 71 is pressed, and the pin 72d is pushed out toward the release body 76 side along the accommodating portion 72c. Then, the pin 72d is the recess 7 of the rotary shaft 71.
1a is transferred to the recess 76c of the releasing body 76, the connection between the rotating shaft 71 and the rotating body 72 is released, and the rotating body 72 is connected to the releasing body 76 via the pin 72d. Thereby, the conveyance of the continuous pouch 1 is stopped, and the central portion of the seal portion 3 is supplied between the lower blade 31a and the upper blade 31b.

After this, the upper blade 31b descends and the lower blade 31b
When the seal portion 3 is cut between the a and the upper blade 31b, the electromagnetic switch 80 is cut off and the restraint of the releasing body 76 is released. Then, the rotating shaft 71 further rotates in the direction of the arrow D, and when the pin 72d faces the concave portion 71a of the rotating shaft 71, the restoring force of the torsion coil spring 75 pushes the pin 72d against the inner surface of the concave portion 76c of the releasing body 76, and the pin 72d is accommodated. Part 72
It is extruded to the rotary shaft 71 side along c. As a result, the pin 72d is transferred from the recessed portion 76c of the releasing body 76 to the recessed portion 71a of the rotating body 71, the connection between the releasing body 76 and the rotating body 72 is released, and the restoring force of the torsion coil spring 75 causes the rotating body to rotate. The pin 72 a of 72 is the receiving portion 7 of the releasing body 76.
The releasing body 76 rotates until it comes into contact with the inner surface of 6b on the side opposite to the arrow D direction, and the rotating body 72 is connected to the rotating shaft 71.
Returns to the initial state. Then, the series of operations described above is repeated.

According to the above embodiment, the rotation shaft 71 and the rotating body 72 are connected and disconnected when the pin 72d is transferred between the rotation shaft 71 and the releasing body 76. Therefore, as the pin 73b is moved along the inner surface of the housing portion 73a of the rotary body 72, the rotary shaft 71 and the rotary body 72 are moved.
As compared with the twelfth embodiment in which the connection between and is cut off, the frictional force acting on the rotating body 72 and the pin 72d is reduced, so that the rotating body 7
The durability of the pins 72d is improved. Therefore, the labor of checking the wear state of each member and the labor of replacing the worn parts by stopping the production line can be reduced at the lowest cost.

In the thirteenth embodiment, the columnar pin 72d is used for disconnecting the rotary shaft 71 and the rotary body 72, but the pin 72d is not limited to this, and may be, for example, a polygonal cross section. You may use a pin of a shape.

In the twelfth and thirteenth embodiments, the continuous pouch 1 is conveyed by the chain 74 to the lower blade 31a and the upper blade 31b. However, the present invention is not limited to this. You may convey the printed matter corresponding to a work to an inkjet printer. In the case of this configuration, a photoelectric sensor is used as the detection means, and the output position of the photoelectric sensor changes, so that the edge of the printed matter is detected and then the printed matter is conveyed by a predetermined amount. It is good to print on.

Further, in the first to eleventh embodiments, the lever 56 is rotated by the electromagnetic switch 55 to restrain the slide of the release shaft 54. In the twelfth and thirteenth embodiments, Although the lever 78 is moved by the electromagnetic switch 80 when restraining the slide of the releasing body 76, the invention is not limited to this. For example, a chuck that is opened and closed by the electromagnetic switch is provided, and the releasing shaft 54 is used by this chuck. Alternatively, the releasing body 76 may be restrained.

Further, in the above-mentioned first to thirteenth embodiments, the suction pads 13c and 14c are arranged opposite to each other in the transport direction of the continuous pouch 1 and in the horizontal direction orthogonal to the transport direction, but this is not restrictive. Instead of this, for example, as shown in FIG. 57 showing the fifteenth embodiment of the present invention, they may be arranged so as to be shifted in the horizontal direction orthogonal to the transport direction. In the case of this structure, the suction pads 13c and 1c are used to convey the thin continuous pouch 1 containing seaweed and the like.
Even when reducing the distance between the 4c, the suction pad 1

In the first to fifteenth embodiments, the clamps 35 are engaged with the pins 32c of the mounting plate 32a, and the mounting plate 32a is rotated as the clamps 35 are raised. However, the present invention is not limited to this, and may be configured, for example, as shown in FIG. 58 showing the 16th embodiment of the present invention.

In the case of this construction, the compression coil spring 32d is interposed between the mounting plate 32a and the base 26, and when the clamp 32b descends, the compression coil spring 3
The seal portion 3 is sandwiched between the mounting plate 32a and the clamp 32b by the elastic return force of 2d. When the clamp 32b rises, the mounting plate 32a rotates while the seal portion 3 is held between the mounting plate 32a and the clamp 32b by the elastic return force of the compression coil spring 32d. Then, the mounting plate 32a is attached to the frame 30.
When it comes into contact with the pin 30b, the rotation stops, and the clamp 32b
Since only the ascends, the sandwiching of the seal portion 3 is released.

Further, in the above-mentioned first to sixteenth embodiments, the seal portion 3 is detected when the suction by at least one of the suction pads 13c and 14c is released, but the present invention is not limited to this. For example, the registration mark is printed on the seal portion 3 of the continuous pouch body 1 and the registration mark is read by a photoelectric sensor, or the continuous pouch body 1 is sandwiched by a pair of rollers to obtain the thickness of the continuous pouch body 1. The configuration may be such that the amount of movement of the roller along the vertical direction is detected.

[0214]

As is clear from the above description, the apparatus for transporting a work according to the present invention has the following effects. According to the means described in claim 1, the carrying amount of the work piece is controlled by disconnecting the connection between the drive source and the carrying means. Therefore, expensive electric means such as a movement amount measuring means and a control device are not required, and the cost of the apparatus is reduced. In addition, only the sum of the distance from the detection position of the detection means to the work position of the work device and the distance from the detected position of the work piece to the work position is signaled that the predetermined position of the work piece is detected. The transportation means was moved. Therefore, even if the pitches between the detected positions of the work piece vary, the work position separated from the detected position of the work piece by a certain distance can be reliably supplied to the work position of the work device. At the same time, since the transport stop timing is obtained from the movement amount of the transport means, the work position can be reliably supplied to the working device without being influenced by the variation in the transport speed of the work.
