DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically sorting storage bags (hereinafter simply referred to as "bag breaks") broken by a bag breaker and cans and bottles.

[0002]

2. Description of the Related Art Cans and bottles generated in ordinary households or vending machines are stored in storage bags, and after collecting these, the bags are broken by a bag breaker for sorting, and the broken bags are stored. Means are used for sorting bags and cans that are transported by a conveyor belt together with the cans and are manually separated from each other, and are used for sorting bags that have been broken by a wind separator.

[0003]

However, in this case, the leftover liquid adheres to the can and the ashes of cigarettes and other dusts are mixed in, so that the sorting operation is extremely troublesome and the removal of the broken bag is particularly required. Is a dirty work, such as the worker himself being contaminated. In addition, when using a wind separator, there are problems that the installation area becomes excessively large and the sorting ability is not sufficient. In view of the above, an object of the present invention is to automatically separate and sort a broken bag from cans and the like, and to improve the sorting ability.

[0004]

In order to achieve the above-mentioned object, the present invention provides an apparatus for separating broken bags from cans and bottles, wherein one side of the rotating rotary cylinder is negatively pressured by a fixed partition wall. The rotary cylinder is composed of an outer cylinder with a small hole, an inner cylinder with a relatively large hole inside, and a filter interposed between the two cylinders. Then, the processing object in which the storage bag and the cans and the like, which are broken by the bag breaking machine are mixed, is supplied to the negative pressure chamber side of the rotary cylinder, and the bag is broken and held by the suction force of the negative pressure chamber. It is distinguished from bottles.

[0005] In the present invention having the above-mentioned structure, among the objects to be treated, the bag rupture is adsorbed and held on the surface of the rotary cylinder on the negative pressure side, and shifts with the rotation of the rotary cylinder, and shifts to the pressure chamber side. Released by At this time, the cans are not adsorbed to the rotating cylinder by their own weight, and then fall downward. At this time, by making the rotary cylinder an inner and outer double cylinder and interposing a filter between them, bags are not sucked into the suction holes of the rotary cylinder, and separation on the pressurizing chamber side is easy.

[0006]

1 to 4 show a first embodiment of the present invention. The sorting apparatus 1 includes a rotary cylinder 2 and a fixed partition wall 3 that partitions the inner hole into two chambers. One chamber is a negative pressure chamber 4 and the other is an atmospheric pressure chamber 5. The partition wall 3 is mounted on a small-diameter fixed cylinder 6 concentric with the rotary cylinder 2, and the fixed cylinder 6 is formed with a perforation 7 that opens only to the negative pressure chamber side, and a fixed suction mechanism (shown in the drawing) is used. (Omitted). Reference numerals 8 and 9 denote support frames that support both ends of the fixed cylinder 6.

The rotary cylinder 2 has a large number of small-diameter holes 10 with flanges 11 and 12 attached to both ends, and is rotatably supported between the flanges and both ends of the fixed cylinder via bearings. Reference numerals 15 and 16 denote packing materials for maintaining airtightness, which are attached to the front end portion and both side portions of the partition wall 3. 20
Is a large-diameter internal gear attached to the inner circumference of one end of the rotating cylinder.
The drive gear 21 attached to the drive motor M is engaged with the drive gear M. Reference numeral 22 denotes a scraper provided for the rotary cylinder 3.

At this time, when the rotary cylinder 3 is formed as a single cylinder as shown in FIG. 3 and a perforation 10 is formed therein, when a part c of the bag breakage a is sucked into the perforation 10, There is a possibility that the portion may be hooked on the perforation 10 to make peeling difficult. In order to prevent this suction, the perforations 10 may be small holes, but this tends to cause clogging due to dust or the like.

In order to prevent this, according to the present invention, as shown in FIG. 4, the rotary cylinder 2 is composed of inner and outer double cylinders 30, 31 and a filter 32 inserted between them.
In this case, even if the perforation 10 is relatively large, there is no danger that a part of the bag break will be sucked into the perforation 10 and caught. By providing the filter 32, fine dust is also adsorbed and does not accumulate inside the rotary cylinder. Of course outer cylinder 3
0, the filter 32 is detachable. 33 is the inner cylinder 31
The reference numeral 34 indicates the distance between the inner and outer cylinders and the packing for maintaining airtightness.

In FIG. 1, reference numeral 40 denotes a conveyor for transporting the workpiece, and reference numeral 41 denotes a chute. The workpiece may be supplied to the negative pressure side of the rotary cylinder 2 from the bag breaking machine directly via the chute. Reference numeral 42 denotes a partition wall that separates a bag break and a can bottle arranged below the sorting device 1.

In the above configuration, the workpiece W dropped and transported by the transport conveyor 40 or directly from the bag breaking machine (not shown) is supplied to the suction side of the rotary cylinder 2 via the chute 41. . As a result, the bag breakage a adheres to the surface of the rotary cylinder 2 due to the suction force of the rotary cylinder 2, moves with the rotation of the rotary cylinder, and the cans b fall as it is. When the bag a adhered to the rotating cylinder 2 moves to the atmospheric pressure chamber side of the rotating cylinder 2, it loses the suction effect and falls. Alternatively, it is scraped off by the scraper 22. Thereby, the bag breaking a and the cans b are separated.

Next, FIGS. 5 and 6 show another example of the sorting apparatus. The previous example shows an example in which the atmospheric pressure chamber 5 is set to the atmospheric pressure. In this example, the atmospheric pressure chamber of the previous example is used as a pressurized chamber so that compressed air is forcibly blown into the atmospheric pressure chamber. That is, the sorting device 50 divides the inside of the rotary cylinder 51 by the partition wall 52,
Supporting bosses 53 and 54 are attached to both ends of the partition wall 52, and are supported by the support frames 55 and 56 by the bosses 53 and 54. One of the chambers divided by the partition wall 52 is a negative pressure negative pressure chamber 57. A suction pipe 58 opening to the negative pressure chamber 57 is passed through one boss 53, and the other chamber is used as a positive pressure pressurizing chamber 60. A pressure air supply pipe 61 opening to the pressurizing chamber 60 is connected to the boss 53. The boss 53 is supported through. Other structures are the same as those of the previous example, and the same components are denoted by the same reference numerals and description thereof will be omitted.

With this structure, when the bag a adhered to the rotary cylinder 51 moves to the pressurizing chamber side, it can be reliably peeled and released by the jetted pressure air.

[0014]

As described above, according to the present invention, the inside of a rotary cylinder having a large number of perforations is divided into two chambers, one of which is a negative pressure chamber, by a fixed partition wall. By using a perforated outer cylinder, an inner cylinder with a relatively large diameter hole inside, and a filter intervening between the two cylinders, the bag breaker and can bottles broken by the bag breaker Is supplied to the negative pressure chamber side of the rotary cylinder, the bag is sucked by the suction force of the negative pressure chamber, the bag is rotated together with the rotary cylinder, and the cans are not suctioned. By dropping, both can be reliably and accurately separated. At this time, the rotating cylinder is an inner / outer double cylinder as described above, and a filter is interposed therebetween, so that a part of the bag break is not sucked and caught in the perforation of the rotating cylinder, and the remaining liquid, It can deal with dirty bags such as butts, and it can reliably peel off in the pressurized chamber side, can automatically sort cans and broken bags, save labor, and be installed compared to a wind separator. This has the effect that the area can be significantly reduced.
