[0001]

BACKGROUND OF THE INVENTION The present invention relates to a garbage bag collected from households and the like and in which cans, bottles, plastic bottles, paper containers (hereinafter referred to as "bottles") are placed. The present invention relates to a bag removing apparatus for separating (hereinafter, referred to as “bag removing”) into bottles and the like.

[0002]

2. Description of the Related Art Such a bag removing method is disclosed in
-966 discloses that a garbage bag hooked on a hook on the inner surface of a drum is separated from the upper portion of the drum by a descending air flow.
A method of collecting by a bag suction nozzle and a bag separator provided in a drum is disclosed.

[0003]

However, the garbage bag hooked on the hook on the inner surface of the drum is separated from the upper part of the drum by a descending air flow, and the garbage bag is collected by a bag suction nozzle provided in the drum. In such a method, a garbage bag may wind around these collecting mechanisms. Also, garbage bags, strings, wires, etc. may hang down from holes or gaps on the outer surface of the drum provided for the purpose of dropping fine residue contained in the garbage or separating the contents in the bag. .
These are not only unsightly, but can also cause mechanical damage, and must be removed manually on a regular basis. Furthermore, if the garbage bag can be broken in the bag removing device (hereinafter referred to as "bag breaking"), the bag breaking device in the previous process becomes unnecessary, and its economic effect including reduction of installation space is extremely high. large.

[0004] Therefore, an object of the present invention is to provide a bag removing apparatus which avoids wrapping of a garbage bag, prevents garbage bags, strings, wires, and the like from hanging down from the apparatus, and has a bag breaking function. And

On the other hand, the exhaust chamber 27 is provided between the remaining approximately three-quarters of the transfer surface B. The transfer surface corresponding to the suction chamber 28 forms a bag suction unit 28a, and the transfer surface corresponding to the exhaust chamber 27 forms a bag release unit 27a. The intake chamber 28 and the exhaust chamber 27 are connected to a supply / exhaust system (not shown), and are set so that predetermined negative and positive pressures are always maintained.

Here, the upper conveying surface A and the lower conveying surface B of the chain conveyor 20, the waste input section, and the bag suction section 2
These are shown in FIG. 4 in order to confirm the respective positional relationships between 8a and the bag releasing section 27a. The upper transport surface A is configured by a waste input section and an upstream side of the bag suction section 28a. On the other hand, the lower transport surface B is constituted by a downstream side of the bag suction section 28a and a bag release section 27a.

The end face of each hollow rod 21 is provided with an air supply chamber 28.
Alternatively, it is opened to communicate with the exhaust chamber 27. Therefore, when each hollow rod 21 is in the bag suction portion 28a and communicates with the suction chamber 28, the hole 22a,
Air is sucked from 22b. On the other hand, when each hollow rod 21 is located at the bag separating portion 27a and communicates with the exhaust chamber 27, air is blown out from the holes 22a and 22b.

The carry-in conveyor 10 is a chain conveyor 2
The waste is thrown in from above the waste throwing section (entrance side of the upper transport surface A). The waste to be thrown in breaks the garbage bag packed with the separated and collected bottles, the separated bottles 95 and the garbage bag 90, and the bottles are packed without breaking the bag properly. A garbage bag as it is, a garbage bag 91 that is about to be broken, and the like are mixed. Loading conveyor 10
A chute 15 toward the entry side of the upper transport surface A
Is installed at an angle.

The upper and lower transport surfaces A of the chain conveyor 20,
A bottle collection conveyor 30 is provided in the gap B. Collection plates 35a and 35b are provided on both side surfaces of the bottle collection conveyor 30 so as to cover the entire length of the entrance side and the exit side of the upper transport surface A. Also, the collecting plate 3
5a and 35b are attached so as to be inclined such that all the bottles 95 that have fallen slide down onto the bottle collection conveyor 30.

An unbroken bag waste collection conveyor 40 is provided directly below the leading end of the upper conveying surface A. The leading end portion 41 of the unbroken bag waste collection conveyor 40 is slightly below the leading end of the upper conveyor surface A in order to reliably receive the waste falling from the chain conveyor 20.
It is arranged to be shifted closer to the left (the left side in FIG. 2).

Below the lower conveying surface B of the chain conveyor 20, the bag collecting conveyor 5 extends over the entire length of the bag releasing section 27a.
0 is provided. The bag collection conveyor 50 is disposed below the unbroken bag waste collection conveyor 40.

Above the entry side of the upper conveying surface A, a bag breaking means 60 is provided. The bag breaking means 60 is constituted by any one of a shot blast means for jetting shot blast, a high pressure water jetting means for jetting high pressure water, a laser light irradiating means for irradiating laser light and the like.

Further, above the central portion of the chain conveyor 20 and slightly near the entry side, a curtain 80 is laid at right angles to the upper transport surface A and the transport direction. The width of the noren 80 is provided substantially the same as the width of the chain conveyor 20. The lower end of the noren 80 is arranged to be slightly above the upper end of the hollow rod 21.

Next, the operation based on the above configuration will be described.

The waste materials 90, 91 and 95 carried in by the carry-in conveyor 10 slide on the chute 15 at the leading end of the carry-in conveyor 10, and enter the waste charge portion of the chain conveyor 20 (the entrance side of the upper conveying surface A). ). Above it, a bag breaking means 60 is provided, and the unbroken garbage bags in the waste are broken by shot blasting or the like.

The bottles 95 dropped on the upper transport surface A
Since the interval between the hollow rods 21 is provided sufficiently larger than the outer diameter of the bottles 95, the collecting plate 35
a, 35b or dropped on the transport surface of the bottles collecting conveyor 30 and collected. The bottles in a posture parallel to the transport direction are turned by the curtain 80 so as to be perpendicular to the transport direction, and then fall from the gap of the hollow rod 21.

On the other hand, the bag 90 in the waste sticks to the projection 25 of the hollow rod 21. Further, while the holes 22a and 22b are sucked by the hollow rod 21 by suctioning the air, the bag 90 is held on the conveying surface by the bag sucking section. It is transported to the end of 28a. The bag 90 that has reached the bag detaching portion 27a while being adsorbed is released from the hollow rod 21 by air blown out from the holes 22a and 22b of the hollow rod 21.
, Fall down, and are collected by the bag collecting means 50.

In the case where the bag is not completely broken by the bag breaking means 60 and the garbage bag 91 is left with the bottles remaining therein, the garbage bag 91 is moved to the tip of the upper transport surface A (outgoing side). ), It is detached from the hollow bar by its own weight, dropped on the unbroken bag waste collection conveyor 40, and collected.

Thus, the bottles 95 and the garbage bag 9
0, and furthermore, the waste containing the bottles packed or the garbage bags 91 that are about to be broken is not separated into bottles 95, bags 90, and unbroken bags 91. It can be collected separately.

In the above embodiment, the bag removing device is provided with the bag breaking means 60 and the unbroken bag waste recovery conveyor 40. However, the bag breaking means 60 may completely break the bag. If it can be confirmed, there is no need to provide the unbroken bag waste collection conveyor 40. Further, an unbroken bag waste collection conveyor 40 may be provided, and the bag breaking means 60 may be omitted.
