Therefore, as shown in FIG. 5B, the product 39 placed on the product table 19 is inserted into the opening 3 of the bag body 1 through the space between the pair of guide rails 33, 33. The product 39 is, for example, a letter paper or other paper product in which a predetermined number of sheets are stacked, and when an operator manually slides it on the product placing table 19 and sends it in, a pair of guide rails 33, 33 are provided. While being guided, it is easily loaded into the bag body 1 through the opening 3. Therefore, as shown in FIG. 3, each guide rail 33 has a guide path 40 having a U-shaped cross section for guiding the side edge of the product 39 and a taper guide portion 41 for expanding the tail end.

If the worker pushes the bag body 1 toward the bottom portion 2 as it is after loading the products, the sealing piece 4 is separated from the holding means 38, so that the bag body 1 passes through the slideway 42 and the transport table 9 is conveyed. It is slid and dropped to the start side of the transport. Figure 5
As shown in (B), the slideway 42 is provided with detection means 43 such as a laser detector or a photoelectric detector, and detects the bag body 1 passing through the slideway 42. Then, in response to this detection signal, the guide drive means 37 is operated to retract the commodity loading guide means 32 onto the commodity placing table 19 and make it stand by.

The guide driving means 37 of the product loading guide means 32, the air supply device of the air nozzle means 30, the cylinder 28 of the claw piece 27, and the cylinder 22 of the lifting body 206 are all included in the detection means 43. It operates in conjunction with the detection signal.

That is, when the detection signal of the detection means 43 is received, first, the guide drive means 37 is operated to retract the product loading guide means 32 onto the product placing table 19.
At this time, the cylinder 22 slightly moves to raise the lifting body 206 slightly and press the sealing piece 4 of the bag group 100 against the holding means 38 to hold it.

When the backward movement of the product loading guide means 32 is completed, the air supply device is activated to operate the air nozzle means 3.
Air is ejected from 0. At this time, the cylinder 28 operates to raise the claw piece 27. The cylinder 28 raises the claw piece 27 and then immediately lowers the claw piece 27 to hold the lower bag group 100.

During the ejection of the air, the guide driving means 37 is actuated again to advance the commodity loading guide means 32 from the commodity placing table 19 and insert it into the opening 3 of the bag 1. Then, after a lapse of a certain time, the air supply device is stopped and the air jetting from the air nozzle means 30 is stopped.

After that, each time the bag 1 loaded with the products 39 is passed through the slide 42, a detection signal from the detection means 43 is issued, and the same operation as described above is repeated. The above-described operation that operates in response to this detection signal includes the guide drive means 37 of the product loading guide means 32, the air supply device of the air nozzle means 30, the cylinder 28 of the claw piece 27, and the cylinder 22 of the lifting body 206. It is possible to make an interlocking connection electrically, but it is also possible to make an interlocking connection mechanically.

When the bag body 1 on the bag body supporting means 20 is deficient by repeating the above-described product loading operation, the lifting body 206 is lowered by the cylinder 22 and retracted from the opening 205. Then, as shown by the arrow in FIG.
8 is intermittently rotated to move the subsequent bag body supporting means 20 in which the bag body group 100 has been set from the bag body supply position S to the bag body standby position W, and the cylinder 22 again raises the lifting body 206. At the very least, the same product loading operation as above will be restarted.

(Slideway Mechanism) The slideway 42 is shown in FIG.
As shown in FIG. 3, the bag supporting means 20 and the conveyor 10 are composed of a plurality of rollers 44 that form a connecting portion.
As described above, the product placing table 19 and the bag body supporting means 20 are installed in a substantially horizontal state, whereas the transport table 9 is installed at an inclination. That is, runway 4
The transport table 9 is inclined downward from 2 toward the transport guide 16. Therefore, the group of rollers 44 is also aligned along this inclination.

The bag body 1 loaded with the products and sliding on the slideway 42
Slides down while being guided by the receiving wall 15, and stops at the position where the bag bottom portion 2 hits the transport guide 16.

(Conveyance Attitude Control Mechanism) The commodity-loaded bags 1 sent onto the conveyor 10 are sequentially driven by the drive piece 1.
When it is located between No. 4 and No. 14, it is suitably placed on the conveyor 10 as it is and conveyed. For example, the conveyor 10
In the case of intermittently feeding the bag 1, when the bag 1 loaded with the product from the product loading device 18 is fed onto the conveyor 10 via the slideway 42, if the conveyor 10 is stopped and waited, the bag 1 is driven by a driving piece. It is possible to drop it within the interval of 14, 14. However, in order to improve the working efficiency, when the conveyor 10 is continuously fed, the commodity-filled bag 1 sent on the conveyor 10 may be placed on the drive piece 14. For this reason, a transport attitude control device 45 is provided on the transport start end side of the transport table 9.

As shown in FIG. 1, the transport attitude control device 45 includes a support rod 46 provided above the transport table 9 in a direction traversing the conveyor 10 and a pair of belt-shaped members suspended from the support rod 46. It is composed of elastic bodies 47, 47. Further, on both sides of this elastic body, the transport table 9 is provided with blocks 48, 48 which are positioned higher than the upper surface of the conveyor 10 but shorter than the drive piece 14.

Therefore, as shown in FIG. 7 (A), even if the bag body 1 loaded with products is placed on one of the drive pieces 14, the attitude is controlled by the transfer attitude control device 45. . That is, when the bag 1 is sent together with the driving piece 14 and reaches the position of the block 48, the bag 1 is positioned on the block 48 and receives the resistance of the elastic body 47 as shown in FIG. 7B. Therefore, with the elastic body 47 stopping the bag body 1, the drive piece 14 passes under the bag body 1 together with the conveyor 10. When the driving piece 14 passes, the bag body 1 is placed on the block 48 as shown in FIG. 7C, but the bag body 1 is moved to the side surface (conveying direction) by the next driving piece 14 that is continuously transferred. Since the rear surface) is pushed, the bag body 1 is thereby transported against the elasticity of the elastic body 47, passes through the elastic body 47, and is transported in a desired posture.

(Release Sheet Separating Mechanism) The product-filled bag body 1 whose posture is controlled and conveyed by the conveying posture control device 45 continues to have a release sheet peeling device 49 as shown in FIG. Be passed through.

This device 49 comprises a support rod 50 provided above the transport table 9 in a direction traversing the conveyor 10, a pair of air nozzle devices 51, 51 supported by the support rod 50, and the air nozzles. A pair of nozzles 5 facing the release sheet 8 of the bag 1 which is being conveyed from the apparatus
2, 52 are provided. This air nozzle device 51,
51 receives air pressure feeding from an air pump (not shown).

A detection means 53 is provided for activating the air pump when the release sheet 8 of the bag body 1 being conveyed approaches the nozzles 52, 52. This detection means 53
When the sealing piece 4 of the bag 1 that has been conveyed is detected, a signal is output and the air pump is operated. The air pump is operated for a predetermined time until the bag body 1 being conveyed passes through the device 49, continuously ejects air from the nozzles 52, 52, and peels off the release sheet 8 of the adhesive means 6 of the bag body 1. Let it blow away.

On the carrying table 9, the nozzles 52, 5 are provided.
2 is provided with a receiving box 54. The receiving box 54 has an opening on the front side toward the nozzle 52, receives the blown release sheet 8, and receives the box 54.
To discharge below. Although not shown in the drawings, the receiving box 54 is preferably formed of a plate material or a net material having a large number of holes such as punching metal and has air permeability.

(Sealing Piece Standing Mechanism) The bag 1 further conveyed is sent to the sealing piece standing device 55 to hold the sealing piece 4 upright. The standing device 55 is composed of a plate body having an inclined surface 56 whose one end gradually rises in an arc shape. In the case of the illustrated example, a plate-shaped preliminary plate 57 provided along the transport table 9 is provided prior to this standing device 55, and as shown in FIG. The sealing piece 4 is lifted above the upper surface of the transport table 9.
Therefore, when the sealing piece 4 in the floating state is passed through the upright device 55, the sealing piece 4 is gradually raised by the inclined surface 56, and as shown in FIG. Completely stands up along the line.

(Sealing mechanism) The bag body 1 in which the sealing piece 4 is erected is folded back in a folded shape by the sealing device 58 and bonded to the adhesive layer 8.

This sealing device 58 comprises a free wheel roller 59 parallel to the conveying direction, and a cylinder 60 for reciprocating the free wheel roller 59 on the adhesive layer 8 from the rear of the upright sealing piece 4 of the bag body 1. . The idler wheel 59 is pivotally supported by a bracket 63 guided and supported by a frame 62 by a pair of guide rods 61, 61, and connects the cylinder 60 to the bracket 63. A detection means 64 for detecting the bag 1 is provided on the conveyor 10,
When the detection signal from the detection means 64 is issued, the cylinder 60 is driven to reciprocate the idler roller 59 in an instant. Even during the movement of the idler roller 59, the conveyor 1
Since 0 continues to be conveyed, the idler roller 59 is formed to have a long axial length.

As a result, as shown in FIG. 8 (C), the sealing piece 4 of the bag body 1 is folded down by the forward-moving idler roller 59 and pressed onto the adhesive layer 7 by the roller 59. . The idler roller 59 is immediately retracted by the cylinder 60 and stands by.
