It can be placed and displayed on a stand or the like in a standing posture. Then, when the user who has purchased the product opens the bag G, the sealing film 75 may be peeled off from the adhesive layer 75a as shown in FIG. 8C.

(Construction of Conveying Means) As shown in FIGS. 1 and 2, the conveying means F constitutes a drum 9 intermittently rotated by a driving source, and has a bed 10 facing each of the stages. A holding claw 11 for detachably holding the header portion 5 of the bag body G with respect to the side surface of the bed 10 is provided. In consideration of the operation speed of the automatic packaging of goods, the bed 10 includes at least a transfer / extraction stage A, an opening stage B, a product loading stage C, and a sealing stage D.
And four places facing the bag discharging stage E,
It may be provided corresponding to an integral multiple thereof. In the illustrated embodiment,
Eight beds 10 are provided at equal intervals in the circumferential direction of the drum 9. Therefore, the rotating drum F is provided with an interval between adjacent beds 10 during intermittent rotation, that is, 4 in the illustrated example.
Rotate 5 degrees at a time.

In the illustrated embodiment, the bed 10 has on its side a flat bed surface 12 on which two bags G, G can be attached in parallel. A slidable slider 14 is provided, and the bed surface 12
, A pair of holding claws 11, 11 for holding the two bags G, G therebetween is extended from the slider 14. A spring 15 such as a coil spring is externally inserted into the pin 13, and constantly urges the slider 14 to the rear of the bed surface 12 to press the holding claws 11, 11 against the bed surface 12.

As shown in FIG. 1, on the top of the drum 9,
A fixed table 16 that does not rotate is provided. That is,
During the rotation of the drum 9, the fixed table 16 does not move without rotating with the drum 9. This fixed table 16

(Structure of the transfer and take-out stage) Since the pair of transfer / take-out stages Aa and Ab arranged in parallel have the same structure, only one of them will be described. As shown in FIG. 3, the transfer / extraction stage A includes a conveyor 21 disposed below the bed 10 of the rotating drum F, a suction roller 22, and a transfer unit 23.

The conveyor 21 includes a driving source 2 such as a motor.
4 constitutes an endless conveyor belt 26 wound between a drive pulley 25 intermittently driven by rotation and a driven pulley (not shown). The bed 10 of the rotary drum F faces the transfer / extraction stage A. The conveyor 21 is disposed so that the conveying direction of the conveyor 21 is defined. Therefore, a large number of bags G are stacked on the conveyor belt 26 and are transported intermittently in the traveling direction J.

As shown in FIG. 3, a large number of bags G stacked on the conveyor belt 26 are arranged with the header portion 5 positioned forward in the traveling direction and the opening edges 4 facing upward. Sequentially, the upper bag body is overlapped with the lower bag body so as to be displaced forward. In the most preferred example shown in FIG. 3, the header portion 5 of the upper bag is shifted forward to a position where it does not overlap the header portion 5 of the lower bag. In such an overlap state, if a worker breaks down the stacked body G from a stacked state so as to level the stacked body, the thick and heavy header portion 5 moves while being displaced downward. Obtained easily by being forced. In addition, the conveyor belt 26 is intermittently fed corresponding to the above-mentioned displacement distance.

The suction roller 22 is provided on the conveyor belt 2.
When the bag 6 is stopped, the foremost bag of the many bags G is detachably sucked, and the bag can be extended to a front position that does not overlap with the lower bag. For this reason, the suction roller 22 constitutes a roller 28 provided with a large number of suction holes 27 on the peripheral surface, and is connected to suction means such as a vacuum pump (not shown) so that the bag body G can be suctioned to the suction holes 27. And a rotary drive source 2 such as a motor.
The rotation is intermittently performed in the direction of the arrow shown in FIG.
Although not shown, the suction roller 22 is connected to an elevating device such as a cylinder, and is capable of moving forward and backward with respect to the surface of the conveyor belt 26 as shown by a chain line and an arrow in the figure.

When the foremost bag of the plurality of bags G is sent below the roller 28 and stopped by the intermittent transfer of the conveyor belt 26, the roller 28 is moved via the elevating device to the chain line shown in FIG. As shown in (2), the front bag is sucked into the suction hole 27. At the same time or thereafter, the roller 28 is intermittently rotated by the rotary drive source 29, and the sucked bag G for one sheet is moved to the front of the conveyor belt 26. The suction force of the bag body by the suction hole 27 is a small suction force that does not wind the bag body around the roller 28, and the bag body G is formed by the suction hole 27 located at the lowest point of the roller 28. The bag G is detached by its own weight from the suction hole 27 that is moved upward by the rotation of the roller 28. Therefore, by rotating the roller 28 a predetermined number of times, as shown in FIG. 3, the bag G for one sheet is fed out to a front position where it does not overlap with the lower bag, and is brought into contact with the front stopper 30. Stop. When the feeding operation of the bag for one sheet is completed, the roller 28
Stops rotating and is raised by the lifting device as shown by the solid line in the figure, and waits for the next feeding operation.

The transfer means 23 is provided with a suction head 31 for detachably sucking the header portion 5 of the unfolded bag body G.
And an arm 3 for moving the suction head 31 toward the bed 10 of the rotary drum F facing the transfer / unloading stage A.
2.

Although not shown, the suction head 31 has a suction hole provided on the lower surface thereof connected to suction means such as a vacuum pump, and is positioned near the stopper 30 so that the header of the bag body G can be moved. The part 5 is sucked. The suction head 31 is pivotally attached to the tip of an arm 32 via a rotation shaft 33, and is connected to a rotation drive source such as a motor (not shown). It is freely rotatable forward and backward in the up-and-down swing direction via a rotating shaft 33. Accordingly, the suction head 31 is turned downward by the turning drive source as shown by the solid line in the standby state in which the suction head 31 is swung upward as shown by the dashed line in the drawing, and
After being sucked, it is turned upward again. At this time, the sucked header portion 5 is bent upward with respect to the bag body 3 as shown by a chain line in the drawing, and detaches from the stopper 30.

The arm 32 is rotated by a forward / reverse rotation means 34 such as a motor to reciprocate the suction head 31 between a position near the stopper 30 and a position facing the bed surface 12 of the bed 10. . Prior to the rotation of the arm 32, the slider 14 on the bed 10 is pushed by the first unlocking means 17 against the spring 15, and the holding claw 11 is separated from the bed surface 12. Then, when the arm 32 is rotated by the forward / reverse rotation means 34 in a state where the suction head 31 that has sucked the header portion 5 of the bag body G is swung upward as described above, as shown by a chain line in the figure. Then, the header portion 5 of the bag G is moved along the bed surface 12 of the bed 10, and the arm 32 is stopped there. Therefore, after that, when the first unlocking means 17 is retracted, the slider 14 is moved back by the spring 15, and the header 5 of the bag body G is held on the bed surface 12 by the holding claws 11, thereby transferring. Extraction stage A
Is completed. Then, arm 32
Is returned to the original position, and stands by while the suction head 31 is swung upward.

During one cycle in which the arm 32 rotates forward and backward, one cycle of the intermittent feeding of the conveyor 21 and the operation of taking out and transferring one piece of the bag G by the suction roller 22 is completed. As soon as the attachment of the single bag G to the bed 10 facing the transfer / unloading stage A is completed, the barcode printed on the bag G is read by the barcode sensor BS as shown in FIG. The management of the number of sheets of G and the number of work steps are performed. Then, while the arm 32 is separated from the bed 10, the rotating drum F performs a predetermined intermittent rotation, and transports the bed 10 to the next stage while holding the bag G by the holding claws 11.

As shown in FIG. 3, a sensor 35 is provided at a position corresponding to the suction roller 22 in order to control the conveyance of the conveyor 21. This sensor 35
Detects whether the bag G is not deficient during the intermittent transfer of the conveyor 21. If a large number of bags G stacked on top of each other as described above are greatly separated from each other so as not to overlap between them at all, A situation occurs in which the roller G runs idle and the bag G cannot be transferred. Then, in such a case, the sensor 35 detects the deficiency (separation) of the bag body G and gives an abnormal signal to the drive source 24, so that the feeding operation of the conveyor 21 is continued. When the separated portion passes and the bag G continuously comes on the sensor 35,
Release the abnormal signal and perform the expected intermittent transfer.

(Structure of Open Stage) Since the pair of open stages Ba and Bb arranged in parallel have the same structure, only one of them will be described. As shown in FIG.
Is a suction unit that detachably adsorbs a portion of the bag G held by the bed 10 of the rotating drum 9 facing the stage near the opening edge 4 and draws the opening edge 4 in a direction to open the opening of the bag. The opening means 36 is constituted. Specifically, a suction pump 37 and a reciprocating drive source 38 such as a cylinder for moving the suction body 37 toward and away from the opening edge 4 are provided. And the like are provided with suction holes connected to suction means. Therefore, by moving the reciprocating drive source 38 forward and operating the suction means, the opening edge 4 of the bag body is adsorbed to the adsorbent 37, and then the reciprocating drive source 38 is moved back, so that the reciprocating drive source 38 is moved together with the adsorbent 37. The opening edge 4 is pulled to open the opening of the bag body G. The product loading stage C described later
Thus, the opening of the bag is kept open until the product is loaded into the bag G, and after the loading of the product is completed, the suction means is stopped to release the suction of the opening edge 4. .

The opening stage B is further provided with guide means 39 located above the suction opening means 36. The guide means 39 is provided with a guide piece 41 which can be moved back and forth toward the upper portion of the opening of the bag G by a reciprocating drive source 40 such as a cylinder. The guide piece 41
Is rotatably supported via a rotation shaft 42, and can be rotated forward and backward by a rotation driving means such as a motor (not shown). That is, in the state where the opening of the bag body G is opened by the suction opening means 36, the guide piece 41 advanced to the upper part of the opening by the reciprocating drive source 40 is normally rotated so that the tip is downward, Thus, the upper edge of the opening edge 4 is kept open. After the product is loaded into the bag body G by the product loading stage C described later, the guide piece 41 is rotated and returned to a substantially horizontal state, and is separated from the upper edge of the opening edge 4. Is retreated by

And an endless transfer body 49 in which 8 are arranged.

As shown in FIG. 5, the transfer body 49 is provided with a flange portion 51 projecting from the lower edge of an upright sleeve portion 50, and is driven by a motor or the like via a drive shaft 52 provided at the center. It is driven and rotated intermittently by the means. The driving means can share the driving means for the rotary drum 9 of the transport means F. For example, the driving shaft 52 is connected to a transmission means 53 such as a gear.
The transfer body 49 can be intermittently rotated by interlocking with the rotary drum 9 via the. The holding holes 48 are vertically penetrated at equal intervals in the circumferential direction of the flange portion 51, so that the transfer body 49 is intermittently rotated in accordance with the pitch of the holding holes.

The bottom plate 46 is formed of a disk or an annular plate disposed below the flange portion 51 of the transfer body 49, and is appropriately fixed to a base or a base frame. Therefore, the bottom plate 46 does not rotate with the transfer body 49, and closes the holding hole 48 from below. The chute paths 45, 45 are provided just above the open openings of the bags G, G in the open stages Ba, Bb, and are formed by forming the bottom plate 46 into cutouts. It is closed by openable and closable opening / closing means 47 constituted by a piece, and the transfer body 49 that rotates intermittently stops and the holding hole 4 is closed.
When the shutters 8 and 48 face the chute paths 45 and 45, the shutters 47 and 4 are opened and closed by opening and closing drive units 47a such as cylinder devices.
7 is moved backward, whereby the holding holes 48, 48 communicate with the chute paths 45, 45. The drive shaft 5
2 extends downward through the center of the bottom plate 46.

A substantially disk-shaped guide member 54 is disposed above the sleeve 50 of the transfer member 49, and is fixed without rotating with the transfer member 49. As will be described later, the guide body 54 is provided on the side of the flat portion 85 in the group of products H being intermittently transported by the flange portion 51 while the columnar portion 83 of the product H is rotatably held in the holding hole 48.
