[0013]
When the limit switch 6 is turned on, the control unit (not shown) sets the locked lever 9 in the locked state to the unlocked state shown in FIG. The solenoid 7 is driven to rotate the rotary cutter 21 twice, for example.
Further, the solenoid 16 urges the receiving plate 14 horizontally so that the can C can be received.
[0014]
Next, the operation will be described.
It should be noted that the can C has no remaining contents and has a weight of about 25 g.
First, as shown in FIG. 1, when the lid 5 is opened and the can C is inserted into the insertion port 3a, the can C descends along the inclined guide tube 3, but the locking lever 9 is in the locked state. Therefore, as shown by the two-dot chain line in FIG.
Then, as shown in FIG. 2, when the lid 5 is closed, the lid 5 is locked by a lock mechanism (not shown) and the limit switch 6 is turned on. In response to the ON signal from the switch 6, the solenoid 7 is driven so that the locking lever 9 in the locked state is unlocked and then locked again, and the gear motor 42 is operated.
[0015]
When the solenoid 7 is driven in this manner, as shown in FIG. 2, the can C is guided from the inclined guide tube 3 to the vertical guide portion 4, falls into the tube 32, and is received by the receiving plate 14.
When the gear motor 42 is operated, the sprocket 44 is rotated twice in the counterclockwise direction in FIG. 2, so that the rotary cutter 21 rotates the upper blade 22 counterclockwise so as to feed the can C from the front to the rear. At the same time, the lower blade 23 rotates clockwise.
[0016]
When the upper blade 22 rotates in the counterclockwise direction, the drive arm 48 moves back from the state of FIG. 6A to the state of FIG. 6A through the states of FIGS. 6B and 6C. 6A, the driven arm 50 is lifted up by the drive arm 48 to rotate from the state of FIG. 6A to the state of FIG. 6B, so that the cylinder 32 rotates counterclockwise. As shown in FIG. 7, the can C is pushed between the upper blade 22 and the lower blade 23.
The can C pushed into the space between the upper blade 22 and the lower blade 23 in this manner is cut into a strip while being drawn into the space between the upper blade 22 and the lower blade 23, and the storage box arranged below the rear side It is housed in.
[0017]
The cut piece of the can C sandwiched between the upper and lower blades 22 and 23 is scraped off by the upper and lower scrapers 24 and 25 and stored in the storage box.
Then, the upper blade 22 and the lower blade 23 make two rotations, return to the states shown in FIGS. 2, 5 and 6A and stop.
[0018]
Next, when a can C having a weight of more than 50 g and remaining contents is left in the inlet 3a, the solenoids 7, 16 can only support up to 50 g as described above. As shown in FIG. 8, the can C rotates the locking lever 9 to the unlocked state, is guided from the inclined guide tube 3 to the vertical guide portion 4, falls into the tube 32, and moves the receiving plate 14 . pivoted in the time scale direction falls into discharge port.
Then, it is collected in a collection box arranged below the front side.
[0019]
As described above, according to the embodiment of the present invention, the can C can be cut into strips by the rotary cutter 21 and the volume can be reduced so as not to be bulky, so that the transportation efficiency of the empty can C is further improved. Can be done.
Further, the cylinder 32 is swung by a driving mechanism (can feeding driving mechanism) 41 to provide a can feeding mechanism 31 for pushing the can C on the can receiving portion 12 into the rotary cutter 21, and the large-diameter blades 22 b and 23 a are provided with a can feeding mechanism 31. Since the claws are provided, the can C can be reliably pushed into the space between the rotary cutters 21 and the pushed can C can be reliably pulled in and cut.
Further, when the total weight of the can C is equal to or more than a predetermined value, the can receiving portion 12 drops the can C to an outlet, and discharges the can. There is no danger that the remaining contents will be scattered and soiled around, and the clothes and the like of the operator will be soiled.
[0020]
In the above-described embodiment, the rotary cutter 21 is used as the cutter. However, any cutter having another configuration, for example, one of the blades may be fixed as long as the cutter can cut the can C into a strip shape.
Further, the cutter driving mechanism and the can feed driving mechanism are configured by one driving mechanism, but it is needless to say that they can be driven by different driving mechanisms.
Further, in consideration of dropping the can C containing the contents as shown in FIG. 8, after the solenoid 7 is operated, the gear motor 42 is operated, for example, two seconds later, and the receiving plate 14 is pushed onto the can C. The rotation of the gear motor 42 in the counterclockwise direction is detected by a limit switch or the like, and the operation of the gear motor 42 by the signal from the detection of the rotation of the receiving plate 14 by the limit switch is canceled within 2 seconds. In this case, the gear motor 42 does not needlessly rotate.
[0021]
【The invention's effect】
As described above, according to the present invention, the can can be cut into strips by the cutter and the volume can be reduced so as not to be bulky, so that the efficiency of empty can transport can be further improved.
Further, since the cylinder is swung by the can feed drive mechanism to provide the can feed mechanism for pushing the can on the can receiving portion into the cutter , the can can be reliably pushed between the cutters and cut.
Further, when the total weight of the can is equal to or more than a predetermined value, the can receiving portion discharges the can to the discharge port, so that the can containing cut-to-drink contents is cut to scatter the remaining drink. Therefore, there is no danger of the surroundings being soiled or the clothes of the operator being soiled.
