Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to carton cases, comb containers, foamed steel [, 1
- This relates to a method of inserting a film bag into a case, which is employed when inserting a film bag into various cases such as a film box.

BACKGROUND TECHNOLOGY In general, bulk items are transported in a case, but depending on the material of the case and the type of bulk item, the case may be damaged and the quality of the product τ1 may be lost.

Furthermore, when loose items are products, especially refrigerated or frozen foods, the case becomes dirty, making it impossible to reuse the case. Therefore, recently, a film bag is inserted into the case, and loose items are packed into the film bag and transported. Normally, the insertion of the film bag has been done manually, and this method does not allow for efficient insertion. Recently, a new method has been developed in which a vacuum cup is used to open the opening of the film bag, and the film bag is inflated by air pressure and inserted into the case.

Problem to be Solved by the Invention According to the above-mentioned machine type, after the film bag is inserted into the case and the suction by the vacuum cup is released, when the case is separated (descended) from the vacuum device side, air is released. The area around the opening of the film bag may curl up due to resistance, or the film bag may not be inserted properly.

Also, when transporting the case with the film bag inserted to the product packing area, for example in Competition 17, when passing through and covering fire walls etc., pressure differences between floors and rooms may cause damage. As strong winds begin to occur in the first section5, this strong wind causes the film bag to come off.

The first object of the present invention is that the film bag can be inserted into the case reliably, the inserted form of the film bag can be maintained when the case is moved apart after insertion, and the film bag can be removed. There is no need to transport the case (provide for the insertion and removal of the film 4A into the case).

Means for Solving the Problems In order to solve the above problems (1), the method of inserting the film bag into the case according to the present invention is to apply a liquid to at least one outer surface of the case, and to 1. Transfer the film bag in the correct direction: 1. Place the case below the convex μ, and keep the opening periphery of the sent film bag at 0 (M°). "While expanding part 1, supply air from above using the 1A supply device, insert the film bag into the case while turning it over, and then release the air supply and holding, and then open the area around the opening of the film bag. It is pressed against the outside of the case.

According to the structure of the present invention, when the film bag is inserted inside the case while being turned over, the air supply and holding are released, and the area around the opening falls down and is covered over the inside and outside of the upper edge of the case. It will become a monkey. Then, when the area around the opening is pressed against the outer surface of the case (1), the area around the opening can be brought into close contact with the outer surface using the liquid previously applied to the outer surface.

Thereafter, the stopper device 24 is moved forward again to receive the next coupe. When the lift device 19 is at the upper 5th limit of the +t'r frame 85, the arm 99 of the front and rear film pressers 92 is in the 14th position.
As shown in the figure, it is in a horizontal position, and the arms 104 of the left and right film pressers 93 are in a separated position. Therefore, case 7 is transferred to main conveyor 3 by arm 98.104.
carried out without interference. The transported case 9 is received by the stopper device 106 and stopped above the support base 91 during orientation. In this state, the cylinder assembly V188 is extended δ and the lifting frame 85 is raised 5'? Sa I
Then, the support stand 91 that rises as one comes into contact with the lower surface of the case 7, and this lifts the shelf from above the main conveyor 3. A film bag 8 is inserted into the lifted case 7 from the film bag listening device side. Rinawara,
The long film 9 fed down by the interlocking intermittent drive of the feeding device 12 and the bottom feeding conveyor 21 is
When the periphery of the ItI opening 8a faces both suction heads 55, the lowering is stopped. At this time, in the spacing device 17, the movable base 32 (which is spaced apart from each other as shown by the imaginary line in FIG. 9 and the imaginary line in FIG. 10), and the cam device 65 is connected to the Since both cam rollers 73 and 74 face their respective small diameter portions 69a and 70a,
As shown by the imaginary line in FIG. 10, the suction head 55 is in a vertical position, and the arm 62 is in a rearward position. As mentioned above, the lower end of the long film 9 whose lowering has stopped is detected by a detection device such as a phototube type, and the lower end of the long film 9 is detected by a photocell type detection device.
Both rotating tables 32 are moved closer to each other by ff34.

By contracting the cylinder device 45, the vertically moving lever 38 is swung around the front and rear surface pins 36, and the first push rod 43 is pushed out. As a result, the left-right lever 42 swings around the vertical pin 40, and the movable base 32 is moved closer via the second push-pull lever 44. Due to this approaching movement, the first

To this, J, refilm side 8b is,! It will enter along the shape of the liI groove. In this state, the cam device 65
When the cylinder device 76 is operated, the seventh cylinder device 76 of the cam body 68
Upon rotation in the direction of the arrow in the figure, the large diameter portion 69c of the first cam 69 acts on the first cam 40a 73, thereby rotating the first rotating shaft 51 via the block 71, Both suction heads 55 are swung away from each other as shown by the imaginary lines in FIG. Due to this oscillation, the adsorbed film side 8b is moved from side to side.
At this time, since the suction position is shifted, the listening is performed reliably. Due to the rotation of the cam body 68 described above, the large diameter portion 70c of the second cam 70 acts on the second cam follower 74, thereby rotating the second rotating shaft 52 via the block 72, and further The clamp piece 63 is moved upward via the arm 62. Then, the clamp piece 63 enters into the opened opening 8a, and the first

Cutting of the film side 8b (Inu Samurai 1J) has been completed by the cutting device r?16 above, and therefore the part 8a is held between the film bags 8. Next, the actuating device The movable base 32 is prevented from being separated by the reverse operation of 34 as described above, but at this time, the intermittent drive of the delivery device VE112 and the lower conveyor 121 is performed again, and air is supplied from the air supply device 18. Supplied. Then, the film bag 8 is sucked around the opening 8a.
The opening 8a is expanded while being sent out by the lower conveyor A721. Then, after the specified opening and expansion, only sending out M
At this time, since air is supplied from above, the film bag 8 is fed out.
is turned over and inserted into the case 7 which is lifted by lift 'A td 19. After insertion, the air supply is stopped, and the operation of the cam device 65 causes the respective small diameter portions 6
By making 9a and 70a face each other, first, the clamp piece 6
3 moves down, the clamp is released, and the suction head 5
5 into a vertical position. Before and after this, the suction force on the suction head 55 side is released, and the suction on the film side 8b is also released. Then, the area around the opening 8a of the film bag 8 falls, and the film y18b portion is covered with the case 7, both inside and outside. In this state, both film pressers 92.9
Extend the cylinder device 97.103 of arm 9.
8. 104 is swung around the axes of the rotating shafts 95 and 101. As a result, the presser foot 99.105 shown in FIG. 13 is brought into contact with the outer surface of the case 7 via the film side 8b, thereby clamping the film side 8b. In this pressing, the film edge 8b is brought into close contact with each of the outer surfaces 7a and 7b through the liquid 25 that has been applied in advance to the outer surface 7a of the 111 part and the side outer surface 7b. While maintaining this clamping posture with close contact, the q lowering frame 85 is lowered and the case 7 is unloaded onto the main conveyor 3. The difference in stroke at this time can be absorbed by free rotation of the presser foot L]-R 99.105. Then, the j'-me 98.104 is separated;
Then, the stopper device 106 is released 't! As a result, the case 7 into which the film bag 8 has been inserted is transported to the next step. Even if a strong wind acts on the case 7 during this transportation, the film side 8b will not be exposed to the liquid 25 as described above.

Since the bag 8 is in close contact with the bag 8, it will not come off.

The spraying process 11 in the coating device 22 is time-controlled to prevent overcoating.

In the above embodiment, a method was shown in which the liquid 25 was applied to the three outer surfaces 7a and 7b, but this may be applied to only one surface of the +'+it section outer surface 7a, or only two surfaces of the left side outer surface 7b. In this case, the case 7 can be conveyed continuously without stopping.

When two stopper devices 24 are provided and used separately as shown in FIG. 16, the rear outer surface 7c can also be coated with the rear spray device 26c.

The coating device 22 includes a brush 11 as shown in FIG.
0 may be used; in this case, the base side of the brush 110 is immersed in the liquid 25 of the liquid tank 111 and Jj <.

Effects of the Invention According to the present invention having the above configuration, with the case positioned below the transfer path, the area around the opening of the sent-out film bag is listened to at the IA position, and air is supplied from the air supply device. As a result, the film bag can be turned inside out while being covered, and can also be inflated downward by air pressure, and the bulge can be inserted into the case. Next, after stopping the air supply, by releasing the hold on the opening device, the periphery of the opening can be dropped and the upper edge of the case can be covered both inside and outside. At this time, since the liquid has already been applied to at least one of the outer surfaces of the case, by pushing the area around the 00 opening that has been washed away as described above onto the outer surface of the case,
The area around this opening can be brought into close contact with the outer surface via a liquid. This allows the case to be transported without the film bag coming off.
