(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, the 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 the figure. 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 in the drawing, the suction head 31 has a suction hole provided on the lower surface thereof connected to suction means such as a vacuum pump and the like. 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. Therefore, 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 sucking the header portion 5 of the bag G, again. It can be turned upward. 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. Then, while the arm 32 is away from the bed 10, the rotating drum F performs a predetermined intermittent rotation, and the holding claws 11
The bed 10 is conveyed toward the next stage while holding the bag G.

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) The pair of open stages Ba and Bb arranged side by side have the same structure, and only one of them will be described. As shown in FIG.
Is a suction unit that detachably adsorbs a portion near the opening edge 4 of the bag G held by the bed 10 of the rotary drum F facing the stage 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

(Composition of Product Loading Stage) The pair of product loading stages Ca and Cb arranged side by side have the same configuration symmetrically arranged, so only one will be described.
As shown in FIGS. 4 and 5, the product loading stage C includes a hopper 43 disposed above the opening stage B,
Commodity supply means 44 for supplying the bar-shaped commodities H to the hopper 43 one by one in a substantially horizontal posture.

As shown in FIG. 5, the product supply means 44 includes an endless conveyor belt 45 wound between a drive pulley intermittently driven by a drive source such as a motor and a driven pulley. And one of the pulleys 46 constituting the driving pulley or the driven pulley is provided with a claw-shaped gear 47.
Are provided coaxially. Preferably, as shown in FIG. 4, a pair of pulleys 46a and 46b are mounted on both sides of a gear 47 mounted on a central portion of the rotating shaft 48, and a conveyor belt 45a is mounted on each of the pulleys 46a and 46b. 4
5b. For example, a large number of bar-shaped products selected by a writing instrument such as a ball-point pen or a felt-tip pen are stacked so as to straddle a pair of conveyor belts 45a and 45b, and are intermittently transported toward the gear 47. Before reaching the gear 47, a leveling member 50 that is swingable via a fulcrum 49 is provided above the conveyor belt 45. Accordingly, the stacked bar-shaped products H stacked on the conveyor belt 45 are passed by only one of them, due to the interference of the leveling member 50. Further, at this time, the attitude of the bar-shaped product H destined for one piece is controlled such that the longitudinal axis of the product is perpendicular to the traveling direction of the conveyor belt 45.

As shown in FIG. 5, the claw-shaped gears 47 form the product holding grooves 51 at equal intervals in the circumferential direction.
One bar-shaped product H transported by the conveyor belt 45 is received by the product holding groove 51 between the belts 45a and 45b so as to be scooped from below, and is intermittently rotated in the direction of the arrow shown in the figure. At this time, a rotatable brush roller 52 is attached to the upper part of the gear 47,
The bar-shaped product H is correctly placed in the product holding groove 51.
Therefore, when the product holding groove 51 that has received the bar-shaped product H comes to the turning point at the end of the conveyor belt 45, the product holding groove 51 is turned downward and the bar-shaped product H falls. Although not shown, the leveling member 50 is provided with a sensor for detecting a shortage of the bar-shaped product H, and the products are not densely stacked on the conveyor belt 45 and are located between the product groups. In the case where there is an interval, an abnormal signal is given to the drive source of the conveyor belt 45 so that the feeding operation of the belt 45 is continued, the separated portion of the product group passes, and the bar-shaped product H continues.
Is detected by the sensor, the abnormal signal is released,
The intended intermittent transfer of the belt 45 is performed.

The hopper 43 is provided with a receiving chamber 54 which is located at the drop point of the bar-shaped product H and which opens 53, and a guide chamber 55 which is communicated with the receiving chamber 54 and extends downward.

Therefore, when the bar-shaped product H supplied by the product supply means 44 falls into the receiving chamber 54, it is supported at two points by the fixed support means 56 and the temporary support means 57,
It is kept almost horizontal. Therefore, the reciprocating drive source 8
When the pin 59 is retracted from the receiving chamber 54, the support by the temporary receiving support means 57 is released, and the bar-shaped product H is released.
Rotates about the fixed support means 56 as a fulcrum, falls in a substantially vertical position with the tip of the product H facing downward, and
Sent to 5. For this reason, as shown in FIG. 4, the guide chamber 55 steeply inclines one lower wall 60 following the fixed support means 56, while gently inclines the other lower wall 61 on the opposite side. Makes it possible to change the posture from a substantially horizontal posture to a substantially vertical posture as described above, and forms a vertically long holding chamber 62 for holding a bar-shaped product H in a substantially vertical posture below the guide chamber 55. I have.

The holding chamber 62 formed below the guide chamber 55 has a product outlet 63 facing the open opening of the bag G in the open stage B.
Is provided with shutter means 64 for opening and closing the shutter freely. In the case of the illustrated embodiment, the shutter means 64 is connected to a reciprocating drive source 65 such as a cylinder, and is capable of reciprocating between a position for closing the product outlet 63 and a position retracted from the outlet 63. is there.

Therefore, the bar-shaped product H is held in a substantially vertical position by the holding chamber 62, and is supported by the shutter means 64.
Is moved to open the product discharge port 63, the bar-shaped product H
Falls, enters the opening of the bag G in the open stage B, and is loaded into the bag G. When the loading of the product H into the bag G is completed, the shutter means 64 moves to immediately close the product outlet 63. The intermittent operation of the product supply means 44, the forward / backward movement of the temporary receiving support means 57, and the forward / backward movement of the shutter means 64 are interlocked with each other, and therefore, as shown in FIG. A product H in a substantially horizontal position is on standby, a product H in a substantially vertical position is on standby in the guide room 55, and two products are on standby in the hopper 43. In addition, bag G
When the commodity H is loaded in the opening stage B, the suction of the suction body 37 in the opening stage B is released, and the locking by the guide piece 41 is released, and the rotating drum F rotates intermittently by a predetermined amount.

(Structure of Seal Stage) When the bag G loaded with the commodity H is sent to the seal stage D by the intermittent rotation of the rotary drum F while being held on the bed 10 by the holding claws 11, The opening edge 4 of the bag body G is sealed with a seal.

For this reason, as shown in FIG. 6, the seal stage D is provided with a pressing member 66 and a hot plate 67. As described above, in the embodiment in which the pair of bag bodies G, G are suspended in parallel on the bed 10, the pressing member 66 and the hot plate 67 simultaneously press the opening edges 4 of the pair of bag bodies G, G. It is formed in a wide range of dimensions.
