Next, the operation of the interior bag folding device according to the present invention configured as described above will be explained.

The roller 3 for the drive roller conveyor 2 is rotated counterclockwise by a drive L-tor 5 via a drive chain 7. The box 6 into which the interior bag 4 has been inserted is conveyed from the right side in FIG.
It is stopped (state shown in Figure 1).

After that, the box cylinder 12 arranged at the bottom of the lifting platform 8
Pressurized air is supplied from a pressurized air source (not shown) to the lower side of the platform 8, and the platform 8 is raised and stopped at the position shown in FIG. Next, pressurized air is supplied to the rotor low actuator 30a, 30b from the pressurized air source (not shown).
The vertical lever 26a is fixed to the movable part of the rotary actuators 30a and 30b.

26b rotates in the direction of the arrow in FIG. 2, and in the middle of this rotation, the tips of the vertical levers 26a, 26b engage with the upper side walls 4a, 4b of the interior bag 4. Then, while pulling the two side walls 4a, 4b of the interior bag 4 outward, the vertical levers 26a, 26b further rotate, as shown in FIG.

It stops at the position shown in Figure 3. In this state, interior bag 4
The upper parts of the two orthogonal side walls 4C and 4d are inclined inward.

Next, the lever slide cylinder 36a.

Pressurized air is supplied from a pressurized air source (not shown) above the lever slide cylinder 36a,
The rotary actuators 40a, 40b and the horizontal lever 42a, 121) fixed to the movable part 36b are lowered and stopped at the position shown in FIG. Here, the horizontal levers 42a and 42b press down one orthogonal side wall 4c of the bag 4. The plane of the position of the horizontal levers 42a, 42b is shown by two-dot chain lines in FIG.

Therefore, when pressurized air is supplied from the pressurized air source (not shown) to one supply hole (not shown) of the rotary actuator/IOa, 401), the rotary actuators 40a, 40b move in the direction of the arrow in FIG. begins to rotate. This rotary Akujiko bottom - evening 40a.

Since the horizontal levers 42a, 12b are attached to the movable portion of the bag 40b, the horizontal levers 42a, 42+) are prevented from rotating on the first orthogonal side wall 4C of the bag 4 in the direction of the arrow in FIG. Therefore, one orthogonal side wall 4C of the interior bag 4 is folded. As the rotation progresses, this horizontal lever 42a.

When 42b reaches A, A', the vertical side wall 4d of the interior bag 4 is not folded, so the horizontal lever 42a.

42b enters under the other orthogonal side wall 4d of the interior bag 4, rotates further, and stops at the position shown in FIG. Here, the other orthogonal side walls 4d of the interior bag 4 are folded up.

Next, pressurized air is supplied to the upper side of the pad cylinder 34 from a pressurized air source (not shown), and the pad 32 attached to the movable part of the pad cylinder 34 is lowered, and the interior bag 4 is Orthogonal side wall 4C.

b rises. However, since the pad 32 presses the two orthogonal side walls 4c and 4d of the interior bag 4, the two orthogonal side walls 4c and 4d are maintained in a folded state.

Next, when pressurized air is supplied from the pressurized air source (not shown) to one supply hole (not shown) of the pair of rotary actuators 46a, 46+), the movable parts of the rotary actuators 46a, 46b are The attached pair of arms 44a, 44b rotate in the direction of the arrow in FIG. 9, and reach the position shown by the solid line from the position shown by the two-dot chain line.

At this time, the two side walls 4a, 4b of the interior bag 4 are folded together with the inner flaps 6a, 6b of the box 6.

When the pressurized air supplied to the pad cylinder 34 is switched from the upper side to the lower side, the pad 32 taken up by the movable part of the pad cylinder 34 rises.

After that, the rotary actuators 46a, /16b
When the supply of pressurized air is switched from one supply hole to another (not shown), the arms 44a, 44+) attached to the movable parts of the acticoators 46a, 46b (1) rotates in the opposite direction of the arrow in FIG. 9 and returns to the position indicated by the two-dot chain line in the same figure. However, at this time, the two side walls 4a, 4b of the interior bag 4 as well as the inner flaps 6a, 6b of the box 6 are held together by the arms 44a, 44b for a certain period of time.
Because it was pressed down, the creases were completely fixed and only slightly returned.

Next, the pressurized air supplied to the lower side of the box cylinder 12 is switched to the upper side. Then, the lifting platform 8 attached to the movable part of the box cylinder 12 is lowered, and the boxes 6 are placed on the driving roller conveyor 2.

The pressurized air supplied to the lower side of the stopper cylinder 16 is roughly switched to the upper side. Then, the stopper 14 attached to the movable part of this stopper cylinder 16
is descending.

Therefore, the rollers 3 of the drive roller conveyor 2 are rotated counterclockwise by the drive motor 5 via the drive engine 7, so the boxes 6 are conveyed to the left in FIG. The box 6 is sealed by the box machine.

``Effects of the Invention As is clear from the description of the embodiments, according to the present invention, the inner bag is automatically folded after being filled with objects to be transported, so the entire container filling line for objects to be transported can be improved. It has become possible to become unmanned.
