Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty can collecting machine for crushing empty cans of juice, beer and the like and separately collecting them into aluminum cans and steel cans.

[0002]

2. Description of the Related Art Conventionally, an empty can collecting machine of this type has a structure in which an empty can is crushed in one step by a press plate reciprocating by a drive mechanism. However, in that case, the support mechanism of the press plate is complicated and requires many parts, the required space becomes large, and the capacity of the drive mechanism must be increased, so that the cost tends to increase. Further, it is necessary to hold the empty can in a horizontal posture with one hand and open the lid of the empty can inlet port with the other hand, which is troublesome to operate. Since the number of bottled beverages has increased, the conventional collection machine for empty cans requires a separate empty bottle collection box. Further, in the case of continuous charging, it takes time and effort to open and close the charging port as described above, and is structurally unsuitable for continuous processing. Further, since the mechanism presses one can per revolution of the motor, when the press is insufficient, the can remains in the press section and causes canning. Further, since the motor that constitutes the press mechanism is of the vertical axis type, it is difficult to obtain and it becomes expensive. In addition, the number of parts constituting the press mechanism increases. Also, the number of parts from the input port to the press section is large. Further, since the distribution portion of the can has a large inertia, an actuator having a large torque is required.
Also, the announcement is uniform and does not feel familiar. As prior arts, JP-A-1-321098 and JP-A-2-92

FIG. 2 is a side view taken along line II-II of FIG. On the front surface of the cover 2 fixed to the upper end of the inspection lid 1 of FIG. 2, there are an empty can input port 4 (FIG. 1) into which the empty can 3 is input in the direction of the arrow and an empty bottle input port 5 beside it. A trailing dropping chute 6 (FIG. 2) is provided behind the empty can charging port 4 and the rear end of the charging chute 6 is a substantially V-shaped cross section between the first gate 7 and the second gate 8. The space 9 is open immediately above the front end. A vertical fixed receiving plate 12 and a movable pressing plate 13 which constitute a pressing portion 11 are arranged on the lower right side of the second gate 8 in FIG. 1, and the fixed receiving plate 12 is provided between the fixed receiving plate 12 and the movable pressing plate 13. Swash plate 15a that connects to the upper end of the space 14 having a substantially V-shaped cross section and the space 9 described above, and the upper half that connects the space 9 to the empty bottle storage box 16 at the lower left end, and the lower half that descends to the left. The guide plate 15 having the bent plate 15b is fixed.

The movable press plate 13 has spaces 9 and 14 at its lower end.
It is rotatably supported by a horizontal shaft 18 extending in the front-rear direction parallel to the empty cans 3a, 3b supplied therein, and when opened (empty can receiving position) shown in FIG. 1, a vertical plate 13a at the lower end is fixed. A gap 19 through which the crushed empty can 3d can pass with the receiving plate 12
The vertical plate 13a is continuously connected to the inclined plate 13b which is inclined upward from the upper end of the vertical plate 13a. The left end of the rod 21 is connected to the right end face of the upper end of the movable press plate 13 via the universal joint 20. The right end of 21 is connected to an eccentric pin 25 of an output disc 24 of a geared motor 23 via a universal joint 22. In FIG. 1, the eccentric pin 25 is located at the right end position, whereby the movable press plate 13 is held at the empty can receiving position farthest from the fixed receiving plate 12. A drive mechanism A is configured in which the geared motor 23 and the rod 21 reciprocally move the movable press plate 13 between the empty can receiving position of FIG. 1 and a pressurizing position in which the eccentric amount of the eccentric pin 25 is pressed to the left by two times. is doing. Two
A bracket 6 is fixed to a frame (not shown), and the geared motor 23 is fixed to the bracket 26. Reference numeral 27 is a control panel, 29 and 29a are empty bottles, 30 is an aluminum can storage box, 31 is a steel can storage box, 32 is a power lamp, 33 is a speaker, 34 is a container, 35 and 36 are hinges, and 37 is a supporting leg. .

A plurality of steel sensors 40 are mounted on the fixed receiving plate 12 facing the gap 19 and are spaced apart from each other in the front-rear direction.
When it is detected that the steel can (empty can 3d) has passed through the gap 19 regardless of the size, the solenoid motor 42 (FIG. 2) of the distribution plate 41 below the gap 19 is energized, and as shown by the solid line in FIG. Further, the distribution plate 41 inclined toward the aluminum can storage box 30 side is switched to the posture inclined toward the steel can storage box 31 side as indicated by a two-dot chain line 41a. The steel sensor 40 detects the passage of the steel can depending on the amount of eddy current even when the aluminum can has an opening / closing lid attached to the steel can. Since the movable press plate 13 is made of iron material, the sensitivity is increased so that only the passage of the steel can can be detected without detecting the movable press plate 13. An aluminum sensor may be used instead of the steel sensor 40. In that case, distribution board 41
Is normally located at the position of 41a, and switches to the position of the solid line 41 when an aluminum can is detected. In addition, the aluminum sensor is placed only in the center of the length of the empty can, and even if aluminum is used for the lid of the steel can, it prevents the aluminum lid from being detected and mistaken for an aluminum can. A porcelain sensor may be used as the steel sensor 40.

The first gate 7 supports the empty can 3a in a horizontal posture from below, and the empty can 3a is supported by the first gate 7 and the second gate 8.
In order to guide from the space 9 between them to the space 14 of the press part 11, the space 14 side is inclined downward to the right so that the space 14 side becomes lower,
The upper part on the opposite side of the space 14 is connected to a rotary solenoid 45 (FIG. 2) via a rotary solenoid shaft 44 extending in the front-rear direction which is parallel and horizontal to the empty can 3a. First
When a load of a predetermined value or more is applied to the gate 7, the right end portion of FIG. 1 descends to drop a heavy empty can or the like (a bottle or a can having a built-in object) downward. like,
Both ends of a rotary solenoid shaft 44 fixed to the first gate 7 with screws 46 are rotatably supported by bearings (not shown), and the rotary solenoid shaft 44 is connected to the rotary solenoid shaft 44a via a joint 47, and When the other end of the torsion coil spring 48, one end of which is fixed to the right end of the solenoid shaft 44a, is fixed to the case 49, and when the empty can 3a is mounted on the first gate 7, the first gate 7 is elastically moved to the posture of FIG. However, when a heavy bottle or the like is placed, it is rotated in the direction of arrow B against the elastic force of the torsion coil spring 48, and the heavy bottle or the like is dropped from the first gate 7. 50 in FIG.
Is a solenoid fixed to the case 49, 51 is a rotary rotor driven in the solenoid 50, 52 is a key for fixing the rotary rotor 51 to the rotary solenoid shaft 44a,
Reference numeral 53 is a mounting bracket. Torsion coil spring 4
8 can be attached to the left end of the rotary solenoid shaft 44. Further, instead of the torsion coil spring 48, a tension coil spring may be attached to one end of the first gate 7.

The second gate 8 in FIG. 1 stops the empty can 3a on the first gate 7 and is fixed to another horizontal rotary solenoid shaft 55 whose upper portion is parallel to the empty can 3a and extends in the front-rear direction.
The rear end of the rotary solenoid shaft 55 is connected to the rotary solenoid 56 (FIG. 2).

At the lower end of the charging chute 6 of FIG. 2, a metal sensor 58 is mounted facing the internal space of the charging chute 6, and this metal sensor 58 indicates that a metal such as aluminum or iron has passed through by an eddy current. Is detected and the drive signal is given to the drive mechanism A. The upper and lower photoelectric sensors 59, 59a and the left and right (front and back sides of the paper surface of FIG. 2) photoelectric sensors 60, 60a are mounted on the diameters of the charging chute 6 on the upstream side and the downstream side of the metal sensor 58. 5
When 9, 59a, 60, 60a detect that an object has passed and the metal sensor 58 does not detect metal (for example, when a bottle or a plastic container is inserted from the empty can insertion port 4), The circuit is configured so that the first gate 7 opens. When a bottle or a can full of contents arrives on the first gate 7, the first gate 7 opens to drop the bottle or a can full of contents, while the second gate 8 holds a vertical closed position. . Children insert their hands into the throw-in chute 6,
A photoelectric sensor 59, which is filled with empty cans in the charging chute 6,
The circuit is configured to stop the drive mechanism A when 59a, 60, 60a continue to detect an object for a predetermined time (a preset time of the timer 54, for example, 4 seconds). The photoelectric sensors 59, 59a, 60, 60a are moved to one side of the inner surface of the throw-in chute 6 even when a child inserts his / her hand,
Two pairs are provided in different directions so that the hand can be detected with certainty.

As described above, in the present invention,
An empty bottle inlet 5 dedicated to an empty bottle was provided. Even if the bottle is accidentally put in the empty can inlet 4, the metal sensor 58 and the photoelectric sensor 5
Non-metals were discriminated by 9, 59a, 60, 60a, and the mechanism was dropped into the empty bottle storage box 16. By removing the can receiving portion from the charging port and making the charging ports 4 and 5 simply openings, it is easy to load an empty can. A method of gradually pressing the empty cans several times by the swing motion of the movable press plate 13 enables continuous pressing of the empty cans. By changing the loading direction of the empty cans, the empty cans 3d after pressing were oriented vertically and in the front-rear direction, and the inertia of the mechanical portion required for distribution by the distribution plate 41 was reduced. A metal sensor 58 is used to discriminate the material of the empty can and an empty bottle or other container, and a steel sensor 40 or an aluminum sensor is used to discriminate between steel and aluminum. Photoelectric sensors 59, 59a, 6 on the charging chute 6 behind the charging port
When 0 and 60a are installed in double and a hand is put in the input chute 6, a safety device for stopping the geared motor 23 of the drive mechanism A is provided. Further, a function of a weight sensor is added to the receiving portion (first gate 7) of the empty can 3a.

When the empty can 3 enters through the empty can inlet 4, the material is confirmed by the metal sensor 58 when passing through the charging chute 6, and falls into the empty can receiving portion (space 9) composed of the first and second gates 7 and 8. . For objects that are heavier than normal empty cans such as leftover drinks, open the first gate 7 with a weight sensor, and guide plate 15
Is guided to enter the empty bottle storage box 16. When the first gate 7 is not opened because it is metal and the second gate 8 is opened, and the empty can 3a falls into the space 14 of the press section 11, the movable press plate 13 moves like 3b, 3c, and 3d. Pressed one after another. When the empty can 3d reaches the steel sensor 40 when the self-weight drop and the press are repeated several times, the steel sensor 40 senses in the case of a steel can, and the distribution plate 41 arranged therebelow is immediately indicated by 41a. Three
In preparation for the fall of the crushed empty can 3d which is inclined to the 1 side.
The movable press plate 13 is automatically stopped when the empty can 3b is pressed and is pressed a predetermined number of times (for example, 5 to 6 times). The distribution plate 41 arranged below the press section 11 is
Normally, it is inclined toward the aluminum can storage box 30 side. Only when a steel can (empty can 3d that has been crushed) passes through the gap 19,
Although it operates as described above, when the steel sensor 40 detects the steel and presses the steel plate a prescribed number of times, the mechanism returns to the original (solid line). As described above, the pressed empty can 3d is sorted by the steel sensor 40, and the sorting plate 4
After being sorted by 1, it is stored in the lower storage boxes 30, 31. The movable press plate 13 of the press unit 11 has a mechanism in which the eccentric pin 25 of the output disc 24 of the geared motor 23 changes the rotational motion into a linear motion and swings the horizontal shaft 18 as a fulcrum. However, as the drive mechanism A for swinging the movable press plate 13, a hydraulic or pneumatic cylinder mechanism may be adopted. After pressing, depending on the material of the empty can, "Thank you for steel can bring me again", "Wow ~ Thank you for aluminum can, please bring me again", and announce from the speaker 33 with the voice of a child in a dialect. We are giving consideration to the collection of empty cans.

4 and 5, 65 is a rubber buffer (shock absorber), 66 is a holding plate, 67 is a set screw, and FIG. 6 is a front view of the rubber buffer 65. Input chute 6 (Fig. 2)
The metal sensor 58 arranged at the lower portion of the can generally has a limited detection range. For example, when a small can passes through the upper part of the cylinder in the charging chute 6, the can may not be detected. The shape of the buffer 65 shown in FIGS. 4 to 6 is devised so that the buffer 65 holds the empty can 3 under the cylinder of the charging chute 6 and the metal sensor 58 can reliably detect the empty can 3. That is, the buffer 65 is made of a thin disk-shaped rubber plate, and after radially cutting 68 a portion through which the empty can 3 passes, leaving a portion in contact with the upper surface of the empty can as a triangular lip 69, on the other hand, The part that contacts the lower surface is cut off. By doing so, the can is pressed downward by the triangular lip 69. Further, the rubber plate 70 on the cut side is also given a certain length. this is,
There is a difference between the wide opening of the can and the inner diameter of the charging chute 6, and when the can is inserted along the charging port, the inner surface of the charging chute and the can are not parallel and the metal sensor 58 part is installed. Since the metal sensor 58 may not detect the passage of the can due to the jumping motion, the cut is made in a size corresponding to the inner diameter of the charging chute 6 or slightly smaller than this in order to prevent this. Due to this, despite the original size of the inlet. The can is supported by the cut lip of the rubber and passes while making contact with the inner surface of the charging chute in parallel, so that the metal sensor 58 reliably detects the can. It should be noted that a can input pitch control gate may be provided at the input port, which closes the input port for several seconds each time the can is input.

Reference numeral 72 in FIG. 1 denotes a horizontal ridge (perpendicular to the paper surface of FIG. 1). The empty can 3 b supplied to the pressing unit 11 receives an upward force between the movable press plate 13 and the fixed receiving plate 12 when being pressed. By this force, empty cans 3b, 3
Since c slips upward between the movable press plate 13 and the fixed receiving plate 12, the number of times the movable press plate 13 swings until the press is completely completed increases, the press processing time becomes long, and cans are packed during continuous loading. May occur. As a countermeasure against this, the inclined plate 13b of the movable press plate 13 or the fixed receiving plate 1
Two or more horizontal weld overlays were applied at suitable positions on either or both sides to form a ridge 72 for preventing the can from slipping.

[0021]

According to the first aspect of the present invention, the structure of the press section 11 is simplified because it takes no time to put it in. After the volume of the empty can 3 is reduced by the pressing unit 11, the empty can 3 can be separately stored. Continuous feeding to the empty can feeding port 4 and continuous processing are possible. Since the empty can 3 is gradually pressed to 3b, 3c, and 3d, even if the pressing is not completed a prescribed number of times, the empty can 3 is repressed at the time of pressing the next empty can and does not cause canning. It is easy to make a small capacity. The number of parts of the press section 11 from the empty can inlet 4 to the press section 11 is greatly reduced. Further, a low-cost general-purpose product such as a horizontal motor geared motor 23 can be used as the press motor. Since the crushed empty can 3d drops downward in the gap 19 in a vertical posture, the distribution plate 41 actuator (solenoid motor 42) can be a small torque one. Steel sensor 40 has a narrow gap 1
Since it is attached to the 9th part, steel cans and aluminum cans can be reliably separated.

According to the second invention, the empty bottle is prevented from being erroneously supplied to the press section 11.

According to the third aspect of the present invention, even if a bottle, a leftover can, or a can that has become heavier by placing stones in an empty can due to mischief is put into the empty can input port 4, these are supplied to the press section 11. Instead, it is stored in the empty bottle storage box 16 side, so that a machine failure can be prevented.

According to the fourth invention, even when the lid of the steel can is made of aluminum, the steel can and the aluminum can can be reliably separated.

According to the fifth aspect of the present invention, it becomes easy to detect a non-metal container such as a bottle or a plastic, and even if a child accidentally puts his or her hand in the empty can inlet 4, the safety device works and the press section 11 stops. So it's safe.

According to the sixth invention, the buffer 6 is provided at the inlet.
By providing No. 5, it is possible to provide a certain degree of moderation for continuous feeding, and it is possible to prevent trouble such as canning due to excessive feeding.

According to the seventh aspect of the present invention, the empty cans 3b and 3c are prevented from slipping upward, and the cans are pressed reliably, so that the required number of swings of the movable press plate 13 is reduced, and the cans are not jammed. It can be prevented from occurring.
