[0006]

In the empty can collecting machine according to the present invention, it is possible to accurately select whether the introduced empty can is an empty can used for beverages or a dangerous spray can when collected and pressed. When the empty can is loaded, the loading port of the empty can provided on the front surface of the housing is formed to have a size equal to or smaller than the predetermined length and thickness of the empty can. As a result, it is possible to prevent the introduction of an empty can that is longer and thicker than a can used for a beverage such as a cassette type gas cylinder.

When a spray can having a predetermined length and thickness or less is charged, and if a relatively large amount of combustible gas remains in a liquid state inside the spray can, behind the charging port. The weight is detected by the weight detection means provided in the support member that supports the empty can inserted from below,
For example, it is stored inside without pressing.

Even when the inserted empty can is a spray can having a length and thickness not more than the predetermined values and a large amount of weight is not detected by the weight detecting means, the driving force is applied to the supporting member in the inclined direction. An opening / closing member that is opened / closed by the power from the source to prevent or releases the movement of the empty can on the support member is provided to temporarily prevent the movement of the empty can. When the outer diameter detecting means provided in the vicinity of the support member detects that the empty can on the support member has a predetermined second thickness or less, the opening / closing member maintains the closed state and prevents the empty can from being collected. However, as an example, press is not performed. When it is detected by the outer diameter detecting means that the empty can exceeds the second thickness, it is determined to be a proper empty can, the opening / closing member is driven to open, and the empty can is housed inside and pressed. And so on. This prevents a situation in which an empty can used for beverages and to be pressed is erroneously selected as a spray can.

A shutter motor 37 for opening and closing the opening / closing plate 33 is connected.

FIG. 5 is a flowchart for explaining the operation of this embodiment. When the empty can 16 is loaded into the empty can collecting machine 11, the cover 29 is opened and the empty can 16 is loaded. At this time, the size of the input port 13 is configured so that the empty can 16 cannot be charged larger than the size of the 500 ml can which is the largest can used as a beverage as described above. Oversized empty can 16 for such beverages
Is, for example, a gas cylinder of a cassette type stove, and its introduction is prevented. In step a1, the process waits until the empty can sensor 32 detects the insertion of the empty can 16. Step a
When the loading of the empty can 16 is detected at 1, whether or not the sorting sensor 30 is turned on in step a2, that is, the empty can 16a having the outer diameter smaller than the height H1 of the sorting sensor 30 is loaded. Detect whether or not.

When step a2 is negative, the height H1
This means that an empty can 16 having an outer diameter larger than that, that is, an empty can 16 having an appropriate size has been loaded, and the step a3 is performed.
The open / close plate 33 rises as the printer 37 is driven, and the empty can 16 on the support plate 31 falls into the press device 19. Step a4
Then, the weight sensor 43 detects whether the empty can 16 has an excessive weight exceeding a predetermined weight. If the determination in step a4 is negative, step a5
Then, the empty can 16 is pressed, sorted in step a6, and collected in one of the collection boxes 21 and 22.

If the determination in step a2 is affirmative, the empty can 16 on the support plate 31 is an undersized type having an outer diameter of about W3 and is regarded as a spray can of cosmetics or the like. At this time, in step a7, the motor 37 remains stopped and returns to step a1. That is, the empty can 16 is the support plate 3
1 remains on and waits for removal. If the determination in step a4 is affirmative, it is considered that a large amount of beverage or the like remains inside, and the sorting process is performed in step a6 while the pressing process is stopped in step a8.

Thus, in this embodiment, the charging port 13
The shape prevents the insertion of an excessively large empty can, and the sorting sensor 30 detects a thin empty can such as a cosmetic spray can, and the thin can is taken out without being collected inside. If the empty can has an excessive weight, it is detected by the weight sensor 43 and is collected without being pressed. That is, when a gas cylinder such as a flammable gas or a spray can of cosmetics is about to be charged into the empty can collecting device 11, the gas cylinder is prevented from being charged, and the spray can is pressed even if it is charged. Without collection boxes 21, 22
Will be collected. This prevents the risk of accidentally pressing a cylinder of flammable gas.

[0020]

As described above, according to the present invention, when the empty can is loaded, the empty can inlet provided on the front surface of the housing corresponds to the predetermined length and thickness of the empty can. Since it is formed to have a size equal to or smaller than that, it is possible to prevent an empty can, which is longer and thicker than a can used for a normal beverage such as a cassette type gas cylinder, as an example. When a spray can having a predetermined length and thickness or less is charged, and if a relatively large amount of combustible gas remains in a liquid state inside the spray can, it is charged behind the charging port. The weight of the empty can is detected by a weight detecting means provided on a supporting member that supports the empty can from below, and the can is stored inside without pressing, for example.

Even when the inserted empty can is a spray can having a length and thickness not more than the predetermined values and a large amount of weight is not detected by the weight detecting means, the driving is carried out to the tilting side of the supporting member. An opening / closing member that is opened / closed by the power from the source to prevent or releases the movement of the empty can on the support member is provided to temporarily prevent the movement of the empty can. When the outer diameter detecting means provided in the vicinity of the support member detects that the empty can on the support member has a predetermined second thickness or less, the opening / closing member maintains the closed state and prevents the empty can from being collected. However, as an example, press is not performed. When it is detected by the outer diameter detecting means that the empty can exceeds the second thickness, it is determined to be a proper empty can, the opening / closing member is driven to open, and the empty can is housed inside and pressed. And so on. This prevents a situation in which an empty can used for beverages and to be pressed is erroneously selected as a spray can.
