A device as described in Japanese Patent No. 44360 is known.

The configuration of the apparatus has a conveyor means by a belt conveyor and a cutting means by a cutter, and a pair of endless rotation belt mechanisms are arranged on the side of the belt conveyor so that the proximity portion becomes the apex, and the speed is correspondingly increased. A fork is provided on the connecting member between the pair of endless rotation belts so as to match the traveling speed of the belt conveyor.

The operation of the above apparatus will be described. One end of a cigarette packaged product conveyed by a belt conveyor is cut off by a cutter and incised.

Then, with a fork, a few cigarettes are removed from the cigarettes that are lightly compressed and packaged, and the arrangement between the cigarettes is broken to eliminate the compressive stress generated by the binding of the package exterior. .

After that, the exterior of the cigarette is turned upside down, and the remaining cigarette is gravity-dropped and taken out.

[Problems to be Solved by the Invention] However, according to the package unpacking device described in Japanese Patent Publication No. 49-44360, even if some cigarettes are taken out,
The remaining cigarettes may become jammed inside the package exterior.

In this case, even if the exterior is turned upside down, the remaining cigarettes do not fall naturally and the entire cigarette cannot be taken out from the exterior.

In addition, when the exterior is turned upside down, the exterior itself may fall along with the remaining cigarettes in the middle, and the cigarette and the exterior may not be separated.

An object of the present invention is to provide a packaged product unpacking device that can reliably take out all the cigarettes and can separate the cigarettes from the exterior.

Install the unpacking section with the cutter and the front roller on the mounting shaft of the rear roller of the belt conveyor of the unpacking section, and mount the rear roller on the mounting shaft of the vertical axis core. Between the and, the belt conveyor around which the needle belt is hung, is arranged corresponding to the upper and lower belt conveyors of the unpacking section, and the take-out section provided with a vibrator and the front roller, the belt conveyor of the take-out section. Attach to the rear roller mounting shaft, attach the rear roller to the vertical axis mounting shaft, and hang the belt between the front roller and rear roller. The first gist is that each belt conveyor of the unloading section is provided with a sending section arranged corresponding to the belt conveyor. The second gist is that it has a protrusion protruding by 2 to 5 mm.

[Operation] According to the present invention, first, in the unpacking unit, the packaged product sandwiched between the belts and transferred is unpacked by the cutter on the way.

Next, at the take-out part, the packaged product is transferred while being securely sandwiched by the protrusions of the needle belt, and at this time, the unpacking end is gradually moved downward from the side and shaken by the vibrator. The cigarette falls from the exterior, and then the exterior is discharged at the delivery unit.

[Example] An example of the package unpacking device of the present invention will be described below with reference to the drawings.

FIG. 1 shows a front view of an embodiment of a package unpacking device of the present invention, and FIG. 2 shows a plan view of the same device with a part thereof omitted.

Two round belts 10 and 10 are laid between and.

The front side of the first belt conveyor 3 is located below the hopper 1, and the second belt conveyor 4 is the first belt conveyor 3
The front side is shorter and is located on the first belt conveyor 3.

The distance between the first belt conveyor 3 and the second belt conveyor 4 is about the thickness of the package.

Regarding the rotation direction of the first belt conveyor 3 and the second belt conveyor 4, the first belt conveyor 3 is facing upward and the second belt conveyor 4 is facing downward on the front side. The package is sandwiched between the belt conveyor 3 and the second belt conveyor 4 and transferred to the rear side.

Further, a disk-shaped cutter 5 which is rotated by a motor (not shown) is provided on the side of the conveyor.

In the figure, 11 is a pressing roller, 12 is a receiving roller, 7a is an extruding rod, and 31 is a guide material.

(3) Take-out section The take-out section is the same as the third belt conveyor 14 in which one front roller 13 is attached to the outside of the mounting shaft 8 of the rear roller 9 of the first belt conveyor 3 of the unpacking section. Part 2
Outside the mounting shaft 8 of the rear roller 9 of the belt conveyor 4,
It comprises a fourth belt conveyor 15 to which one front roller 13 is attached, and a vibrator 16 provided on the side of the conveyor.

The third belt conveyer 14 and the fourth belt conveyer 15 include front rollers 13, 13 and a mounting shaft 17 having a vertical axis.
Needle belt 1 between the rear rollers 18 and 18 attached to 17
It is a product of 9,19.

As shown in FIG. 3, the needle belt 19 has needle-like projections 20 planted on its surface, and the projections of the projections 19 have a length of about 2 to 5 mm. preferable.

This is because if the protrusion is smaller than 2 mm, the package cannot be sufficiently held, and if the protrusion is larger than 5 mm, the protrusion 20 cannot smoothly sandwich the package.

In this case, the third belt conveyor 14 and the fourth belt conveyor
The distance from 15 is about the thickness of the package.

The rotation directions of the third belt conveyor 14 and the fourth belt conveyor 15 are such that the third belt conveyor 14 and the fourth belt conveyor 15 are wound inward.
