[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unpacking machine for separating bags from contents and bags by breaking bags such as general wastes in bags made of vinyl or the like.

[0002]

2. Description of the Related Art In a conventional bag-opening machine, while a general waste in a bag such as a vinyl bag is moved by a belt conveyor, the bag is broken by a blade above the conveyor and the internal waste is discharged. . In some cases, waste in a bag is put into a rotating cylinder, and the bag is broken by a blade provided on the inner periphery of the cylinder.

[0003] Further, an upper portion has an inlet for an object to be processed,
A pair of unpacking axes each having an unpacking blade on the outer periphery are arranged in parallel in a unpacking chamber having a treated material discharge port at a lower portion, and both axes are mutually inwardly directed toward the input port. In some cases, the rotation speed of the unpacking shaft is higher than that of the other unpacking shaft.

[0004]

Among the above-mentioned prior arts, those using a conveyor require a large area for installation, and there is a problem in removing bags after processing. Also,
The rotating cylinder type has a problem that broken objects such as bottles in the waste discharged from the bag fall and collide with each other and are damaged.

[0005] Further, in the case of the type in which the opening blade is rotated, bags such as broken vinyl are wound around the opening blade provided on the opening shaft on the high-speed rotation side.

In order to prevent this, even if the opening blade of the high-speed rotating side is formed into a tapered shape that is difficult to wind or a scraper is provided, a flexible and easily expandable material such as vinyl is always wound around the opening blade of the high-speed side. There was a problem.

An object of the present invention is to solve the above-mentioned problems of the conventional bag-opening machine by providing a bag-opening machine in which a blade provided on a high-speed side bag-opening shaft has a polygonal shape. is there.

[0008]

In order to solve the above-mentioned problems, the present invention provides a pair of unpacking chambers having an inlet for an object to be processed at an upper portion and an outlet for an object to be processed at a lower portion. Arrange the opening axes parallel to each other, and move both opening axes toward the input port.
And the rotation speed of one unpacking shaft
The above-mentioned unpacking machine rotated faster than that of
And fix multiple polygonal blades to the high-speed unpacking axis
The low-speed unwinding shaft has multiple hook-shaped unhooking blades on the outer circumference.
That is, a plurality of blades are fixed.

[0009]

The present invention has the above-described structure, and the garbage-filled vinyl bag or the like put into the inlet is bitten between the blades of the pair of unpacking shafts, and the difference in rotational speed causes the vinyl or corrugated cardboard to drop. It is cut off at the corner of the outer periphery of the blade on the high-speed side, and is discharged from the discharge port together with the glass bottle, iron can, aluminum can, etc. contained in the bag, and heads for the next sorting machine.

In the above operation, since the blade on the high-speed side is polygonal, a bag of broken vinyl or the like is quickly discharged without being wound.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS.
An opening 3 is provided on the upper side of the bag-opening chamber, and an outlet 4 is provided at the lower end of the bag-opening chamber 1. Reference numeral 5 denotes a bag-opening shaft provided in front of the bag-opening chamber 1, and reference numeral 6 denotes a bag-opening shaft provided in the rear of the bag-opening room 1, all of which have a large-diameter hollow shape. Is a small-diameter side wall 2 as shown in FIG.
It is supported by a bearing provided on the outside.

At the ends of the shafts 5, 6, sprockets 10,
11 is fixed, and sprockets 14 and 15 fixed to the output shafts of driving means 12 and 13 including motors and reduction gears provided on the frame 7 and the sprockets 10 and 11 are attached with endless transmission chains 16 and 17 to open the bag. Shafts 5 and 6 are shown in FIGS.
, The number of rotations of the driving means 12 and 13 is set so that the shaft 5 rotates at a higher speed than the shaft 6.

A plurality of blades 21 and 22 are fixed to the outer periphery of each shaft 5 and 6, respectively.
A number of hook-shaped opening blades 23 are provided on the outer periphery of the blade 22.

The knife 23 is provided with a knife edge 24, which is provided so as to face the side opposite to the direction of rotation of the blade 22. The outer periphery of the blade 21 and the hook-shaped opening blade of the blade 22 are shown in FIGS.
As shown in FIG. Note that a scraper 25 may be disposed between the blades 22 as needed.

Next, the operation of this embodiment will be described.
When a processed product such as a vinyl bag or a corrugated cardboard containing an iron can, an aluminum can, a bottle, or the like is put into the input port 3, the processed product is a blade of the unpacking shafts 5, 6 rotating in the directions of arrows in FIGS. It is bitten between 21 and 22.

As described above, the processed materials are the blades 21 and 22.
When bitten in between, the vinyl bag or corrugated cardboard is held while being sent to the discharge port by the hook-shaped blade of the blade 22 of the opening shaft 6 having a slow rotation. The outer periphery is cut off at the corners, where the vinyl bag or cardboard is unpacked, and the contents of cans and bottles are discharged. Thus, the blade 2 of the unpacking shafts 5 and 6
The cans and bottles that have passed between 1 and 22 are discharged from the discharge port 4 together with the broken bag.

[0017]

[Effect] According to the above-mentioned structure, the bag is opened and the contents are discharged by inputting a mixture of light and heavy materials such as garbage bags, bottles, cans, or cardboard as they are. , Cardboard etc. are also unpacked. In the process, a flexible and easy-to-extend material such as vinyl tries to wind around a high-speed rotating blade, but since this blade is polygonal and all the corners are obtuse, vinyl bags etc. cannot be wound Since it is quickly discharged to the outlet, it does not hinder the operation of the bag opening machine due to the winding of vinyls.
