Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention automatically separates pouch bags continuously fed by a conveyor or the like into a pouch bag filling and packaging apparatus that fills a pouch bag with a filling material such as a liquid. The present invention relates to a pouch bag transport device for transporting.

[0002]

2. Description of the Related Art Generally, a pouch bag containing a liquid detergent for refilling is widely used. In a pouch bag filling system that fills a pouch bag of this type with a liquid detergent for refilling, the pouch bag filling and packaging device is provided with a pouch bag conveying device that continuously and automatically conveys the pouch bag at a high speed.

In this pouch bag conveying device, for example, Japanese Patent Application Laid-Open Nos. 5-51016 and 7-61423,
As shown in Japanese Patent Application Laid-Open No. 8-11837, a transfer device having a suction pad for sucking the pouch bag is provided between the end position of the conveyor for conveying the pouch bag and the pouch bag filling and packaging device. There is. Then, the pouch bag continuously supplied by a conveyor or the like is sucked by the suction pad of the transfer device so that the pouch bag is separated one by one and fed into the pouch filling and packaging device.

Further, in the pouch bag, a spout portion (pouring spout) is formed at one corner of a substantially rectangular pouch bag body. The spout portion is formed into a substantially tube shape so that liquid detergent or the like can be poured easily. Therefore, since the thickness of this spout part is larger than the thickness of the main part of the pouch bag, when spout parts are bundled with the spout parts aligned in the same direction, The thickness of the portion where the parts are stacked is larger than that on the pouch bag body side, and the balance is poor. Therefore,
A plurality of pouch bags to be packed in a cardboard box, for example, a relatively small number of pouch bags, such as about 7 sheets, should be bundled in a bundle with the spouts aligned in the same direction and staggered so that they do not overlap. The stacks of the pouch bags are alternately stacked with the positions of the spout portions facing the opposite side. (See FIG. 1) Then, the pouch bag is delivered from the pouch tare maker in a cardboard box with a stack of about seven pouch bags alternately stacked so that the spout portions do not overlap and become bulky. further,
When setting the pouch bag from the cardboard box to the conveyor of the pouch bag conveying device, the spout portion is arranged on the front side in the traveling direction and the upper pouch bag is aligned by the front side in the traveling direction and supplied by hand. (See FIG. 2 (B)) Then, in the conventional transfer device, when the pouch bag is transferred from the conveyor of the pouch bag conveying device to the pouch bag filling and packaging device, the pouch bag adsorbed by the adsorption pad advances on the conveyor. It is configured to be conveyed in the direction and transferred to the pouch bag filling and packaging device.

[0005]

In the conventional pouch bag carrier, the pouch bag sucked by the suction pad of the transfer device at the end position of the conveyor is transferred in the traveling direction of the conveyor and transferred to the pouch bag filling and packaging device. Therefore, the transfer stroke of the pouch bag when transferring the pouch bag is relatively long. Here, since the next pouch bag cannot be supplied while the part of the suction pad that holds the pouch bag reciprocates a long transfer stroke, the work of supplying the pouch bag to the pouch bag filling and packaging device is speeded up. There is a difficult problem to do.

In addition, since the tare of the pouch bag is soft and easily deformed, a suction failure of the pouch bag may occur only by the suction of the pouch bag by the vacuum force of the suction pad of the transfer device.
Alternatively, the pouch bag may be separated from the suction pad on the way, and incomplete transportation may occur, which may result in incomplete transportation. Therefore, it is difficult to stably convey the pouch bag, and there is a problem in increasing the processing capacity of the entire pouch bag filling and packaging apparatus.

Further, in the case of the conventional pouch bag supply device, in the manual supply of the pouch bag, it is necessary to make the bulky spout part sneak under the already supplied pouch bag, which makes quick response difficult and the pouch bag filling processing system. There is a problem in improving the processing capacity of.

The present invention has been made in view of the above circumstances, and an object thereof is to speed up the supply of the pouch bag and to stabilize the conveyance of the pouch bag to the pouch bag filling and packaging apparatus. An object of the present invention is to provide a pouch bag conveying device capable of increasing the speed of the pouch bag filling processing system.

The suction pipe line of each suction pad 59 is connected to a vacuum source via a distributor (not shown) so that the pouch bag 1 can be sucked in a predetermined section. Then, the pouch bag 1 adsorbed to the suction pad 59 is conveyed to the pouch bag filling and packaging apparatus in the subsequent step as the drum 21 rotates.

Next, the operation of the present embodiment having the above configuration will be described. Note that FIG. 14 is a time chart showing an operating state of each mechanical portion of the pouch bag transporting device of the present embodiment. When the pouch bag transporting device of the present embodiment is used, the pouch bag 1 is transferred from the cardboard box 2 to the pouch bag supply conveyor 3.
Is manually supplied, and the pouch bag 1 is continuously supplied by the conveyor 3. At this time, the operation of the drive motor 5 of the conveyor 3 is controlled according to the detection result of the presence or absence of the pouch bag 1 by the photoelectric switch 7 at the end of the conveyor 3,
The conveyor 3 is intermittently operated. When the pouch bag 1 is not detected, the drive motor 5 is turned on via the clutch / brake to drive the conveyor 3, and when the pouch bag 1 is detected, the drive motor 5 is turned off via the clutch / brake to move the conveyor. 3 is stopped.

When the pouch bag 1 is supplied to the end portion of the conveyor 3, the rotating impeller 8 is brought into contact with the pouch bag 1 on the conveyor 3 to assist the separation of the pouch bag 1.
In this state, a first horizontal feeding operation of transferring the pouch bag 1 at the terminal end position A0 of the conveyor 3 to the first transfer position A1 adjacent in the horizontal transfer direction by the first transfer mechanism 19, A second lateral feed operation of laterally feeding the pouch bag 1 at the first transfer position A1 to the second transfer position A2 adjacent to the first transfer position A1 by the second transfer mechanism 20. Will continue.

During the first lateral feeding operation, the cam 29 is moved by the vertical movement mechanism 26 of the first transfer mechanism 19.
The parallel link mechanism 28 is driven via the drive link mechanism 30 in accordance with the rotation operation of (1), the suction pad 22 is translated in the vertical direction, and the lateral feed drive mechanism 34 of the lateral feed mechanism unit 27 moves the swing arm 36. The slider 33 moves together with the suction pad 22 in association with the swinging motion of the guide shaft 3.
The pouch bag 1 is slid in the lateral feed direction along the line 2. As a result, as shown in FIG. 11, the first lateral feed operation of adsorbing the pouch bag 1 at the end position A0 of the conveyor 3 by the suction pad 22 and transferring it to the first transfer position A1 is performed as follows. Be seen.

That is, when the first transfer mechanism 19 is operating, the suction pad 22 is moved to the terminal end position A0 of the conveyor 3 by the vertical movement mechanism portion 26 when the pouch bag 1 is detected by the photoelectric switch 7. It At this time,
The open / close valve 41 is opened to adsorb the pouch bag 1 at the terminal end position A0 of the conveyor 3 to the adsorption pad 22.

Then, the suction pad 22 is lifted by the vertical movement mechanism 26 while the suction pad 22 is sucking the pouch bag 1. Then, the suction pad 22 is laterally fed in the direction of the first transfer position A1 by the lateral feed drive mechanism 34 of the lateral feed mechanism unit 27.

Further, when the suction pad 22 moves to the first transfer position A1, the vertical movement mechanism 26 lowers the suction pad 22 to move the pouch bag 1 to the first transfer position A1. To be done. In this state, the open / close valve 41
Is operated to separate the pouch bag 1 from the suction pad 22, and the pouch bag 1 is transferred onto the first transfer position A1.
At this time, the pouch bag 1 is adsorbed by the suction force from the vacuum holes 17a and 17b of the moving table 16 and then the first
The pouch bag 1 is prevented from being displaced by being adsorbed and held by the adsorbing portion 17. At this time, the posture of the pouch bag 1 is not corrected, and the posture of the pouch bag 1 may be slightly bent due to a manual supply to the pouch bag supply conveyor 3.

After that, the suction pad 22 is lifted by the vertical movement mechanism unit 26, and then the suction pad 22 is moved by the transverse feed drive mechanism 34 of the transverse feed mechanism unit 27 to the upper standby position of the end portion position A0 of the conveyor 3. Is returned to the direction.

During the second lateral feed operation, the vertical link mechanism 50 of the pusher drive mechanism 46 of the second transfer mechanism 20 causes the parallel link mechanism 50 via the drive link mechanism 52 as the cam 51 rotates. Is driven to move the pusher 45 in parallel in the vertical direction, and the slider 54 moves together with the pusher 45 to the guide shaft 53 in conjunction with the swing motion of the swing arm 36 by the horizontal feed drive mechanism 55 of the horizontal feed mechanism 49. The pouch bag 1 is slid along the sideways feed direction. In addition, pouch bag 1
At the time of lateral feed, the lateral feed stroke extension mechanism 57 performs an operation of extending the lateral feed stroke by adding an idle distance. As a result, the operation of the pusher 45 is controlled by the pusher controller (not shown), and the pusher 45 transfers the pouch bag 1 at the first transfer position A1 to the second transfer position A2 as shown in FIG. The second horizontal feed operation is performed as follows.

That is, when the second transfer mechanism 20 is in operation, the pusher 45 is previously moved by the lateral feed drive mechanism 55 of the lateral feed mechanism 49 as shown in FIG.
It is moved to the movement limit position on the side and held at the standby position retracted under the moving table 16. At this time, the lateral feed positioning cylinder 58 of the lateral feed stroke extension mechanism 57 is held with the piston rod 58a protruding. Then, the pouch bag 1 is at the first transfer position A1.
The pusher drive mechanism 46 is driven at the time when the pusher drive mechanism 46 is transferred. At this time, the two pouch bag pressing claws 45a and 45b
Is an escape hole 47 from the bottom of the moving table 16 at a position farther to the conveyor 3 side than the rear end of the pouch bag 1 in the lateral feed direction.
A pressing claw projecting operation of projecting onto the movable table 16 through a and 47b is performed.

Subsequently, when the suction pad 22 of the first transfer mechanism 19 separates from the pouch bag 1, the pressing claws 45a, 4a.
5b is moved in the lateral feeding direction of the pouch bag 1 to move the pouch bag 1
The pouch bag pushing-out operation for pushing the rear end portion in the traveling direction of is performed. At this time, the two pressing claws 45 of the pusher 45
a and 45b are moved in the direction of the second transfer position A2 along the two pusher escape holes 47a and 47b of the moving table 16. With the movement of the pusher 45, the pouch bag 1 at the first transfer position A1 is laterally fed in the direction of the second transfer position A2. At this time, during the operation of laterally feeding the pouch bag 1 from the first transfer position A1 to the second transfer position A2, the two pushers 45 are pressed while applying the end surface of the pouch bag 1 to the pouch bag guide members 43a and 43b. The posture of the pouch bag 1 is automatically corrected by pressing the rear end side of the pouch bag 1 in the advancing direction at two points by the pressing claws 45a and 45b and applying it to the pouch bag guide member 43c on the front side in the advancing direction. Then, during the lateral feeding operation of the pouch bag 1, the piston rod 58 of the lateral feeding positioning cylinder 58 is
a is pulled into the cylinder 58 and operated.

Further, the pouch bag 1 is placed in the second transfer position A2.
When the piston rod 58a moves to the cylinder 5,
It is held in the state of being pulled into 8 and operated. At this time, the pouch bag 1 is attached to the vacuum hole 18 of the moving table 16.
The pouch bag 1 is prevented from being displaced by being sucked by the suction force from a and 18b and sucked and held by the second suction portion 18.

After that, the pusher 45 is lowered by the vertical movement mechanism 48, and the two pressing claws 45a and 45b of the pusher 45 are moved to below the moving table 16 through the escape holes 47a and 47b.

Subsequently, the lateral feed drive mechanism 55 of the pusher drive mechanism 46 performs a returning operation for returning the pusher 45 to the movement limit position on the conveyor 3 side. At this time, after the pusher 45 starts to return, the transverse feed positioning cylinder 5
The piston rod 58a of No. 8 is switched to the projected state. Accordingly, when the pouch bag 1 is laterally fed, the lateral feed stroke extension mechanism 57 adds an idle distance to extend the lateral feed stroke, and the two pouch bag pressing claws 45a and 45b are connected to the rear end of the pouch bag 1. It can be moved to a place further away from the conveyor 3 side.

Further, the pouch bag 1 on the second transfer position A2
Is transferred to the feeding drum 21 above the second transfer position A2. During the work of transferring the pouch bag 1, the suction assist mechanism 60 is driven. Then, as shown in FIG. 13, the suction assisting cylinder 61 pushes up the push-up plate 62 in synchronization with the rotation operation of the feeding drum 21. At this time, the suction pad 59 of the feeding drum 21 is vacuumed by the distributor. In this state, the bottom portion of the pouch bag 1 on the second transfer position A2 is pushed out toward the suction pad 59 of the feeding drum 21, and the bottom portion of the pouch bag 1 is sucked by the suction force of each suction pad 59. Then, the pouch bag 1 adsorbed to the suction pad 59 is conveyed to the pouch bag filling and packaging apparatus in the subsequent process as the drum 21 rotates. In addition, pouch bag 1
Is transferred to the next step of the feeding drum 21, and at the same time, the vacuum of the suction pad 59 of the feeding drum 21 is cut off by the distributor.

Therefore, the following effects are obtained with the above-mentioned structure. That is, in the pouch bag conveying device of the present embodiment, when the pouch bag 1 is not detected by the photoelectric switch 7 at the terminal end of the pouch bag supply conveyor 3, the pouch bag supply conveyor 3 is driven to convey the pouch bag 1, and the photoelectric switch When the pouch bag 1 is detected by 7, the conveyor 3 is stopped by the pouch bag supply controller 6. When the conveyor 3 is stopped, the pouch bag 1 at the terminal end position A0 of the conveyor 3 is moved by the first transfer mechanism 19 by the conveyor 3.
Of the pouch bag 1 at the first transfer position A1 adjacent to the first transfer position A1 which is adjacent in the lateral feed direction substantially orthogonal to the transport direction, and then the second transfer mechanism 20 moves the pouch bag 1 horizontally. It is pushed out in the feed direction and transferred to the second transfer position A2. After that, the pouch bag 1 on the second transfer position A2 is loaded by the suction assisting mechanism 60 at the second transfer position A2.
It is adapted to be pressed against the suction pad 59.
Therefore, the pouch bag 1 at the terminal end position A0 of the conveyer 3 is conveyed in the lateral feed direction that is substantially orthogonal to the conveying direction of the pouch bag 1 by the conveyer 3, so that the pouch bag 1 is conveyed in the traveling direction of the conveyer 3. The transfer stroke of the pouch bag 1 can be shortened as compared with the case of transferring to the pouch bag filling and packaging apparatus. As a result, the work of supplying the pouch bag 1 to the pouch bag filling and packaging apparatus can be sped up as compared with the conventional work.

Further, the conveyance path for conveying the pouch bag 1 at the terminal end position A0 of the conveyor 3 to the feeding drum 21 is provided with a first transfer mechanism 19 using a suction pad 22 and a pusher 45.
Since it is configured to be divided into two stages with the second transfer mechanism 20 according to the above, the distance by which the pouch bag 1 is transported by the suction pad 22 of the first transfer mechanism 19 can be shortened. Therefore, even when the pouch bag 1 whose tare is soft is easily deformed, it is possible to reduce the occurrence of conveyance failure.

Further, the pouch bag 1 is sucked by the first suction portion 17 at the first transfer position A1 on the transverse feed conveyance path between the first transfer position A1 and the second transfer position A2. To prevent the pouch bag 1 from being displaced, and similarly to the second transfer position A2 at the second position.
Since the pouch bag 1 is sucked by the suction portion 18 to prevent the pouch bag 1 from being displaced, the posture of the pouch bag 1 conveyed to the first transfer position A1 and the second transfer position A2 can be changed. Disturbance can be reduced.

Further, when the pouch bag 1 is laterally fed to the second transfer mechanism 20 from the first transfer position A1 to the second transfer position A2, the pouch bag guide members 43a and 43b are provided with the pouch bag. While pressing the end surface of the pouch bag 1, the rear end side of the pouch bag 1 in the traveling direction is pressed, and the pouch bag guide member 43 on the front side in the traveling direction is pressed.
A posture correction mechanism 44 is provided to correct the posture of the pouch bag 1 by hitting it on c. And this posture correction mechanism 4
In the operation of No. 4, when the pusher 45 is driven by the pusher drive mechanism 46, the pusher 45 is inserted at the first transfer position A1 at a position that presses the rear end portion of the pouch bag 1 in the advancing direction in the lateral feed conveyance path. In this state, the pusher 45 is driven in the lateral feeding direction of the pouch bag 1 so that the posture of the pouch bag 1 is automatically corrected, so that defective conveyance of the pouch bag 1 can be prevented more effectively. can do. Therefore, the conveyance of the pouch bag 1 to the pouch bag filling and packaging device can be stabilized, and the pouch bag 1
Can be supplied to the pouch bag filling and packaging device in a stable posture.

Further, since the pouch bag 1 is pushed out toward the suction pads 59 of the feeding drum 21 by the suction assisting cylinder 61 of the suction assisting mechanism 60 in synchronism with the rotation operation of the feeding drum 21, the pouch bag is operated. It is possible to eliminate defective conveyance due to a suction error at the suction pad 59 of the feeding drum 21 of the filling and packaging apparatus.

Further, the second transfer mechanism 20 of the present embodiment
Then, a pressing claw projection for projecting the two pouch bag pressing claws 45a, 45b onto the moving table 16 through the escape holes 47a, 47b from the bottom of the moving table 16 at a position farther to the conveyor 3 side than the rear end of the pouch bag 1. Since the operation is performed, the two pressing claws 45a of the pusher 45,
It is possible to surely prevent the pouch bag 1 from being pushed up as in the case where 45b is lifted up just at the rear end of the pouch bag 1.

Further, in the present embodiment, the lateral feed drive mechanism 55 of the pusher 45 is provided with the lateral feed stroke extension mechanism 57 for extending the lateral feed stroke by adding the idling distance during the lateral feed operation of the pouch bag 1. So the suction pad 22
In the case where the same cam mechanism 38 is used to drive the lateral feed operation of the pouch bag 1 by the lateral feed drive mechanism 34 and the lateral feed operation of the pouch bag 1 by the lateral feed drive mechanism 55 of the pusher 45. However, there is an effect that the lateral feed strokes of both can be easily adjusted.

Further, the lateral feed operation of the pouch bag 1 by the lateral feed drive mechanism 34 of the suction pad 22 and the pusher 45.
Compared with the case where the lateral feeding operation of the pouch bag 1 by the lateral feeding drive mechanism 55 of FIG.
It is possible to shorten the lateral feed operation stroke by the lateral feed drive mechanism 55 of No. 5. Therefore, the moving distance per unit time can be reduced as compared with the case where the lateral feed operation stroke of the pouch bag 1 by the lateral feed drive mechanism 55 of the pusher 45 is long, and thus the acceleration can be reduced. As a result, the lateral feed drive mechanism 5 of the pusher 45
Compared with the case where the acceleration is large as in the case where the transverse feed stroke extension mechanism 57 of 5 is not used, the adverse effects on the vibration of the machine, the life of the movable part, etc. can be reduced.

In the present embodiment, the second transfer mechanism 2
Since the link joint 56 forming 0 is an adjustable type,
The position of the second transfer mechanism 20 can be easily adjusted when the width of the pouch bag 1 is changed.

Further, in the case of the pouch bag feeding device of the present embodiment, when the pouch bag 1 is manually fed, since the spout portion 1a is set to the rear side in the traveling direction, the pouch bag 1 which has already been supplied with the bulky spout portion 1a. There is no need to sneak in underneath, and quick response is possible, making it possible to improve the processing capacity of the pouch bag filling processing system.

The present invention is not limited to the above embodiment. For example, in the present embodiment, the conveyor 3
Although the configuration in which the impeller 8 is provided at the terminal end of the
Is not always necessary, and the impeller 8 may be omitted.

Further, it goes without saying that various modifications can be made without departing from the scope of the present invention.
