Description

TECHNICAL FIELD The present invention relates to an empty can collecting machine for pressing empty cans of canned products such as canned coffee, canned juice and canned beer, and sorting and collecting the cans according to their materials. The present invention relates to a distribution device.

(Background of the Invention) An empty can collecting machine for pressing and collecting empty cans such as canned coffee, canned juice and canned beer has been conventionally proposed. However, in the past, these empty cans were collected without sorting them, so when reusing empty cans,
Each time, the material had to be selected, for example, an empty can made of iron and an empty can such as aluminum had to be selected and processed. For this reason, there is a problem that the processing steps of the collected empty cans increase and the efficiency is low. Therefore, it is conceivable that the empty can collecting machine discriminates the material and discriminates according to the material. In this case, a can allocating device for guiding the pressed empty cans to different collection boxes for each material is required.

Conventionally, it has been considered to use an electromagnetic solenoid as this can distributing device, but in this case, if the collection box is full or the can is clogged and the can stops during operation, current will continue to flow to the solenoid and the solenoid will burn out. was there. Further, distribution by a belt conveyor may be considered, but in this case, there is a problem that juice or the like adheres to each part of the conveyor to cause malfunction. Various other sorters are conceivable, but they all have problems that the structure is complicated and a sensor or the like for detecting an operating state during operation is required.

(Object of the Invention) The present invention has been made in view of such circumstances,
Structure when pressing an empty can and sorting it after material selection and collecting foreign matter (stones, etc.) It is an object of the present invention to provide a can distributing device for an empty can collecting machine that can simplify the operation and improve the reliability of the operation.

(Structure of the Invention) According to the present invention, an object of the present invention is to press empty cans loaded from an input port with a pressing device, sort the pressed empty cans by material, and collect them in different recovery boxes. In the can allocating device of the recovery machine, it is located between the pressing device and the recovery box, is arranged immediately below the empty can that drops after pressing, and oscillates so as to guide the empty can that has been pressed into one of the recovery boxes. A plate, an inclination angle regulation means for regulating the inclination angle of the distribution plate, and normal rotation or reverse rotation until the inclination angle is regulated by the regulation means according to the material of the can when energized, and the distribution plate is predetermined. Of the empty can collecting device, which is provided with a motor for tilting and holding the collecting box side and a tilting means for tilting the distributing plate to one collecting box side when the motor is not energized. Achieved.

(Embodiment) FIG. 1 is an overall schematic view of an empty can collecting machine according to an embodiment of the present invention, FIG. 2 is a front view of a press device and a distribution device, FIG. 3 is a side view of the same, and FIG. 4 is its operation. FIG. 5 is an exploded perspective view of the distribution device.

In FIG. 1, reference numeral 10 is a cylindrical empty can, and this empty can 10 is inserted through an input port 12. A loading door 14 that opens and closes with a lower support shaft 13 as a fulcrum is attached to the loading port 12. This closing door 14 has 10 empty cans in its open position.
Is held and dropped to the can passage 16 side at the closed position. The closing door 14 is provided with a habit of returning to the closing direction by a coil spring (not shown). Inside the charging opening 12, the can stopper 18 faces the lower edge of the closed charging door 14.
Are arranged so as to be vertically rotatable. That is, the can stopper 18 is supported by the support shaft 20, and
22 rotates between the lowered position and the raised position of FIG. When the can stopper 18 is in the lowered position, the empty can 10 moves to the can passage 16
It is forbidden to fall into the empty space, and the empty can 10 is allowed to fall in its raised position.

Further, the upper shape of the rear surface of the can stopper 18, that is, the surface hitting the empty can 10, does not push back the can when the can stopper 18 is opened, and when the uncollected can is taken out by opening the insertion door 14, the empty can 10 opens this rear face. It rolls smoothly and is tilted so as not to interfere with the opening operation of the closing door 14.

This insertion door 14 has a metal sensor as a can material discrimination means.
24 is installed. That is, this can material discrimination means
24 is composed of a sensor for magnetic material (for example, iron) and a sensor for non-magnetic material (for example, aluminum). If neither the magnetic sensor nor the non-magnetic sensor is activated, it is determined that the injection error or the empty can 10 is non-metallic.

As shown in FIG. 1, when the empty can 10 is held in contact with the input door 14 and the can stopper 18 inside the input port 12 with the input door 14 closed, the empty can 10 has a predetermined shape and size. Sensor as a means for distinguishing whether or not it is an empty can
26 are provided. The optical sensor 26 is composed of a pair of a light emitting element and a light receiving element that laterally traverse the empty can 10. The opening / closing of the closing door 14 is detected by a limit switch 28 as an opening / closing sensor.

When the closing door 14 is opened, the empty can 10 is placed on it, and the closing door 14 is closed, it is detected by the limit switch 28 that the empty can 10 is at the bottom of the closing door 14 and the can as shown in FIG. It is held by the stopper 18. In this state, the can material discriminating means 24 discriminates whether the empty can 10 is iron or aluminum. The signal from each of these sensors is input to a control device (not shown), and the control device is the metal (iron or aluminum) that was input.
When 14 is closed and the can determining means 26 determines that the empty can 10 has a predetermined shape and size, the solenoid 22
Is excited to raise the can stopper 18. Empty cans for this
10 is released from the can stopper 18 and falls into the can passage 16.
When these conditions are not satisfied, the control device causes the display plate 29 to display that fact without operating the can stopper 18. The control device may specifically announce by voice that there is an inconvenience, for example, that the can is crushed and the material cannot be determined by a voice synthesizer.

Another optical sensor 30 is arranged in the can passage 16, and this optical sensor 30 detects that the empty can 10 has passed through the can passage 16 and operates a press device 32 described later.

The pressing device 32 includes a fixed press plate 34 located below the can passage 16, a movable press plate 36 facing the fixed press plate 34, and a press motor 38 with a brake for driving the movable press plate 36. The rotation of the motor 38 is converted into a horizontal movement of the movable press plate 36 by a cam mechanism (not shown), and the empty can 10 is pressed between the press plates 34 and 36. Reference numeral 40 denotes a weight sensor composed of a swinging lever, and if the empty can 10 is a proper empty can 10 that is not filled with foreign matters such as stones, the empty can 10 is held at the press position, and a pin 42 is used for an empty can that is heavier than specified.
Swing clockwise around the center of the figure to drop the empty can.

Therefore, when the regular empty can 10 falls through the can passage 16, the empty can 10 falls between the press plates 34 and 36 and hits the weight sensor 40 to stop. When the optical sensor 30 detects the passage of the empty can 10, the motor 38 starts operating after a predetermined time and moves the movable press plate 36 to the right in FIG. Therefore, the empty can 10 between the press plates 34 and 36 is pressed, and when the empty can 10 is properly pressed, it passes between the tip of the lever of the weight sensor 40 and the fixed press plate 34 and falls onto the translating device 44. To do.

The distribution device 44 includes a motor 46 located below the pressing device 32, and a distribution plate 48 that is fixed to a rotation shaft 46A of the motor 46 and that swings below the fixed press plate 34 and the movable press plate 36. Prepare The motor 46 has a reduction gear built therein. The distribution plate 48 includes a lower plate 48A fixed to the rotating shaft 46A of the motor 46 and an upper plate 48B fixed to the lower plate 48A. Further, as a tilt angle regulation means for regulating the inclination of the distribution plate 48, a window 48C is provided on the lower plate 48A.
A pin 46B planted in the motor 46 is engaged with this. Therefore, the window 48C is engaged with the pin 46B, so that the distribution plate 48
The swing range of the rocking | fluctuation swings between the solid line position of FIG. 4 which inclined to the collection box 50A side, and the virtual line position which inclined to the collection box 50B side,
The tilt angle is regulated. Here, the distribution plate 48 is the motor
When 46 is not energized, its own weight causes it to lean toward the collection box 50A. Also, the upper plate 48B and the lower plate 4 of the distribution plate 48
8A has a shape in which the fallen empty can 10 always falls.

The motor 46 is energized and operated based on the output of the can material discriminating device 18, and for a can of magnetic metal such as iron, the motor 46 moves the distribution plate 48 to the position shown by the solid line in FIG. For the can of non-magnetic metal such as aluminum, the motor 46 is operated to rotate the distribution plate 48 counterclockwise and tilt it to the left collection box 50B. As a result, the iron cans are sorted and collected in the collection box 50A and the aluminum cans are collected in the collection box 50B.

In this case, since the inclination of the distribution plate 48 is regulated by the pin 46B and the window 48C provided in the lower plate 48A, it is not necessary to sense the turning angle of the distribution plate 48. In addition, when a stone or the like is thrown in, the motor 46 is in a non-energized state, but since the distribution plate 48 is inclined toward the collection box 50A side by its own weight, the thrown stones are collected in the collection box 50A side. . This is because empty can collectors dislike mixing impurities into aluminum.

A can passage sensor (not shown) is installed near the entrance of each collection box 50A, 50B to finally confirm the drop of the can and the output of the sensor is continuous.
It may be configured to detect fullness of A and 50B.

In FIG. 4, the collection boxes 50A and 50B are partition plates 50C.
It is divided by, and the collection amount of each can be adjusted by moving this partition plate 50C left and right.

Therefore, when the loading door 14 is opened to load the empty can 10 into the loading port 12, and the closing door 14 is closed, the can material determination means 24 determines the material of the empty can, and the empty can 10 falls through the through passage 16.
At this time, the optical sensor 26 of the can discriminating means discriminates that the can is an empty can having an appropriate size and shape, and if a seal detecting portion is provided as necessary, this is an empty can with an appropriate sticker attached. If determined, the coin is paid out and the empty can 10 is guided to the press device 32. The empty can 10 is supported by the weight sensor 40 between the fixed press plate 34 and the movable press plate 36.

When the empty can 10 enters the press device 32, the press sensor detects it and the press device 32 is activated. That is, the press motor 38 is activated, the cam rotates once, and the movable press plate 36 reciprocates once. On the other hand, the motor 46 of the distribution device 44 operates when the can material detection means 24 determines that the steel is iron, and the distribution plate 48 collects the iron cans as shown in the solid line in FIG.
Tilt to 50A and hold. If it is discriminated as aluminum, the motor 46 rotates the distribution plate 48 counterclockwise in FIG.
Is rotated to the collection box 50B side and held.

In this embodiment, when the motor 46 is not energized, the distribution plate 48 is provided with an inclining means for inclining the distribution plate 48 toward one of the collection boxes 50A.
Although the swing center of 8 is offset to one side and tilted to one side by its own weight, the present invention may be tilted to one side by a spring or the like.

(Effects of the Invention) As described above, the present invention arranges the distribution plate immediately below where the pressed empty cans fall, the motor inclines the distribution plate, and the inclination regulating means regulates the inclination angle of the distribution plate. With the configuration, canning does not occur,
In addition, when the motor is energized, the distribution plate is configured to collect the cans in a predetermined collection box according to the material of the can.When the motor is not energized, the distribution plate is tilted by its own weight and the stones, etc. Since it is designed so as not to be mixed in a new can, the structure is simple and the operation reliability is improved.
