BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty can recovery device for recovering cylindrical empty cans by reducing their volume.

0002

2. Description of the Related Art As a conventional empty can recovery device for recovering cylindrical empty cans, there is one in which the entire empty can is crushed using a press device. FIG. 5 shows this conventional empty can recovery device, in which a press section 2 of a press device is provided inside a recovery device main body 1 so as to be movable up and down. The loaded cylindrical empty can 3 is inserted into the input port 4.
The empty cans 3 placed at the press position 6 are crushed by the press section 2 and recovered in a compressed state in the recovery section 7 below the press position.

[0003] Reference numeral 8 denotes a substantially L-shaped door body provided in the input port 4 so as to be rotatable in the direction a, and when the empty can 3 is loaded sideways from the input port 4, it is locked until the end of the press. The opening member 9 engages with the door body 8 to prevent the door body 8 from opening, thereby preventing other empty cans 3 from being thrown in while the press device 2 is operating. Additionally, a holding member 10 is provided at the press position 6.
is arranged rotatably in direction b. This holding member 1
A proximity sensor 11 that detects the presence of an empty can 3 is provided on a wall near the press position 6, and the press device is thereby activated when the empty can 3 is introduced into the press position 6. The collecting section 7 can be freely pulled out to the side, for example, and the empty cans 3 can be easily collected after being pressed.

[0004] According to this empty can collection device, the volume of the empty cans 3 can be reduced and space is saved, so that a large number of empty cans can be collected in a small space, and transportation work can be carried out efficiently.

[0005]

[Problems to be Solved by the Invention] However, in the conventional empty can recovery device described above, the empty can 3 is completely cylindrical, and the lid and bottom portions (hereinafter referred to as flat portions) of the empty can 3 are in the pressing direction. Because it is arranged in the vertical direction along the cylindrical part and is completely connected to the cylindrical part, it is difficult to crush, requiring a large force to crush, and the flat part of the empty can 3 remains flat even after pressing. The problem was that it was bulky.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and aims to provide an empty can recovery device that can crush cylindrical empty cans with a high compression ratio using minimal force.

[0007]

[Means for Solving the Problems] In order to solve the above problems, the empty can recovery device of the present invention includes a guide member that holds empty cans in a predetermined position, and a guide member that holds the empty cans at a position where the empty cans are held by the guide member. The apparatus is equipped with a cutting device in which a cutting blade is movably arranged to cut at least a part of the cylindrical portion of an empty can, and a pressing device to crush the empty can cut by the cutting device.

[0008]

[Operation] With the above structure, the empty can is crushed by the pressing device after the cutting device cuts at least a part of the cylindrical portion of the empty can, so the flat portion of the empty can easily escapes to the left and right during pressing, and the cylindrical portion cylindrical empty cans can be crushed with less force and higher compression ratio than before.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Components having the same functions as those of the conventional empty can recovery device are given the same reference numerals, and their explanation will be omitted.

In FIGS. 1 and 2, reference numeral 21 denotes a guide member which is movable upwardly and retractably from the lower part of the holding member 22 which is disposed below the press position 6 so as to be rotatable in the b direction. Empty cans 3 introduced from the press are held at a predetermined position below the press section 2 of the press device. 23 is a spring that urges the guide member 21 upward.

As shown in an enlarged view in FIG. 2, on both sides of the press section 2 of the press device, there are cutting blades 2 for cutting a portion of the cylindrical section 3b of the empty can 3 in the vicinity of the flat section (lid section and bottom section) 3a.
4 is provided rotatably around a horizontal shaft 25, and this cutting blade 24 is rotated via a belt 27 by a drive motor 26 provided at an appropriate location (in FIG. 2, the upper part of the press section 2). These constitute the cutting device 28. Then, when the proximity sensor 11 detects that the empty can 3 has been introduced into the press position,
The cutting blade 24 of the cutting device 28 is rotated, and the press section 2 of the press device is lowered.

In the above configuration, when the empty can 3 is inputted from the input port 4 and introduced to the press position 6 via the introduction passage 5, the empty can 3 is detected by the proximity sensor 11, and the cutting blade 24 is rotated. At the same time, the press device is activated. That is, the press part 2 is lowered while the cutting blade 24 is rotated, and first, as shown in FIG.
is cut off, and then, as shown in FIG. 4, the cylindrical portion 3b of the empty can 3 is crushed by the press section 2. At this time, since only the cylindrical portion 3b of the empty can 3 is crushed, the pressing pressure of the press section 2 can be reduced, and the can can be crushed at a high compression ratio.

[0013] When the empty can 3 is loaded from the input port 4 as in the conventional case, the locking member 9 engages with the door body 8 until the end of the press, and the opening movement of the door body 8 is prohibited. 2 is in operation, another empty can 3 is prevented from being thrown in.

In the above embodiment, the flat part 3 of the empty can 3
Although we have described the case where the can 3 is completely separated from the cylindrical part 3b, cutting a part of the cylindrical part 3b of the empty can 3 also makes it easier for the flat part 3a of the empty can 3 to escape to the left and right during pressing. 3 can be crushed with less force and higher compression ratio than before. Further, the cutting blade 24 may be directly driven by the drive motor 26, or the drive motor 26 may be installed inside the press section 2 or provided at an appropriate external location.

[0015]

As described above, according to the present invention, after cutting at least a part of the cylindrical portion of the empty can with the cutting device, the empty can is crushed by the pressing device, so that the empty can can be crushed during pressing. The flat part can easily escape from side to side, making it possible to crush cylindrical empty cans with less force and higher compression ratio than before.
