The height of the upper receiving position H of the table 2 may be adjusted according to the vertical length of the bag used. In that case, the amount of rotation of the motor 64 per time may be changed. Further, in this embodiment, the table 2 is moved up and down by rotating the screw bolt 63 by the motor 64 as the lifting device 6, but in another embodiment, the table 2 is moved up and down by using the telescopic cylinder. You may make it move.

In this embodiment, the rotating device 7 for horizontally rotating the table 2 has a kerf-shaped cam 71 formed on the outer cylinder 61 of the lifting device 6 and an inner cylinder 62 side. And a cam floor 72 that slides along 71. Two cams 71 and two cam floors 72 are formed at opposite positions of the lower ends of the outer cylinder 61 and the inner cylinder 62, respectively. In the rotating device 7, when the inner cylinder 62 moves up and down with respect to the outer cylinder 61, the cam floors 72, 72 on the inner cylinder 62 side move along the cams 71, 71 on the outer cylinder 61 side. Thus, the inner cylinder 62 (and the table 2) can be repeatedly rotated by a predetermined angle range (60 ° in the illustrated example) as shown in FIG. The drive source of the rotating device 7 is also shared by the motor 64 of the elevating device 6, and the table 2 can be simultaneously moved up and down and horizontally rotated by operating the motor 64 in either forward or reverse directions. It is like this.

As shown in FIG. 2, in this rotating device 7, the direction of the passage 51 between the pair of guide members 5, 5 provided on the table 2 is set so that the table 2 is in the upper receiving position H (see FIG. 3). In the up position, the receiving posture in which the bag Y containing the article (supported by the chute 10) in the vacuum deaeration position 15 can receive the bag Y containing the article when horizontally moved to the bag removing position 16 containing the article. 2 and the position where the table 2 is moved down to the downward pushing position L, the push plate 32 of the pusher device 3 causes the passage 5 to move.
1. The discharge posture that can pass through the inside of 1 (in FIG. 2, dashed lines 5 ', 5'
The posture shown in (1) is to be displaced.

The illustrated bag feeding device for articles operates as follows. At the article bag removing position 16 of the article filling device 1, the article bags Y supported by the chute 10 are sequentially sent in a suspended state.
Is moved up to stand by at the upper receiving position H. When the table 2 is in the upper receiving position H, the guide members 5, 5 on the upper surface of the table 2 are maintained in the receiving posture capable of receiving the bag Y containing articles in the passage 51, and the chute 10
When the article-containing bag Y supported by is sent from the vacuum degassing position 15 to the article-containing bag removing position 16, the article-containing bag removing position 16 is accurately accommodated in the passage 51 between the guide members 5, 5. Will be done.

Then, in this state, when the clamp device 17 located at the article containing bag removing position 16 is opened, the article containing bag Y supported by the chute 10 is allowed to pass through the passage 5 by its own weight.
It is placed on the table 2 in 1.

Next, when the motor 64 of the lifting device 6 is driven in the table lowering direction, the table 2 is rotated by the rotating device 7 (the cam 71 and the cam floor 72) while being lowered, and the table 2 is moved to the maximum position. When the guide members 5, 5 are lowered to the downward movement position (downward extrusion position L),
, The posture (discharging posture) is parallel to the extension and contraction direction of the pusher device, as indicated by chain lines 5'and 5 '.

When the table 2 is lowered to the lower extruding position L, the telescopic cylinder 31 of the pusher device 3 is subsequently moved.
Expands and pushes the bag Y containing the articles on the table 2 by the push plate 32 onto the starting end of the conveyor 4 as indicated by the chain line Y ″ in FIG.
1 stretches and then immediately shrinks.

The bag Y containing the articles transferred onto the starting end of the conveyor 4 includes a shaping machine 41, a cleaner 42, and a leveler 4.
3 and the sealing machine 44 are sequentially processed to form a sealed bag product.

When the push plate 32 of the pusher device 3 is retracted, the lifting device 6 is subsequently operated (the motor 64 is driven in the table moving direction), and the next bag Y containing the article is moved to the bag removing position 16 containing the article. Before being sent, the table 2 is moved up to the upper receiving position H and made to stand by there. At that time, the guide members 5, 5 on the table 2 have the bag Y containing the articles.
Will be suitable for accepting posture. Then, in the same manner, the bag filling work is automatically performed.

When the article-containing bag feeding apparatus of the illustrated embodiment is used, the article-containing bags Y removed from the chute 10 at the article-containing bag removing position 16 on the article filling apparatus 1 side are automatically and sequentially delivered to the conveyor 4 side. Therefore, the manpower is not required for the work of sending out the bag containing the article.

Further, since the table 2 and the pusher device 3 are mounted on the common mounting base 9, the mounting base 9 is put in the article while the table 2 and the pusher device 3 are mounted on the mounting base 9 in advance. It can be installed immediately below the bag removing position 16, and the assembling work becomes easier than when the table 2 and the pusher device 3 are assembled at the installation site.

Further, since the pair of guide members 5, 5 are provided on the table 2, the posture of the article-containing bag Y becomes stable when the article-containing bag Y is placed on the table 2. .

Further, since the table 2 can be moved up and down between the upper receiving position H and the lower extruding position L by the elevating device 6, the impact when receiving the bag Y containing the articles is reduced, and the lower position is lowered. In the above, since the upper end of the article-containing bag Y is completely separated from the chute 10, the article-containing bag Y is not caught on the chute 10 when the pusher device 3 pushes the article-containing bag Y.

Further, when the table 2 is rotated by the rotating device 7, the guide members 5, 5 are oriented in the upper bag receiving position H in the bag receiving direction and the guide members 5, 5 are in the lower pushing position L. It can be directed in the containing bag discharging direction, and even if the receiving direction of the containing bag Y and the discharging direction of the containing bag Y are different, the work can be performed without any trouble.

Further, since the elevating device 6 and the rotating device 7 are simultaneously driven by the single motor 64, the operating time per one time of this article-containing bag feeding device can be shortened. In addition, by sharing the drive source for the lifting device 6 and the rotating device 7 with one motor 64 in this way, the number of parts can be reduced, and the weight and size can be reduced by the shared use.
