The restriction inclined portion of the restriction frame that swings together with the contact is brought into contact, and the upward movement of the restriction pin is restricted. As a result, when the sorting means is allowed to swing, the opening of the shutter is prohibited, and safety is ensured. Further, since the lower end (opening side) of the groove of the restriction frame is formed in a divergent shape, the restriction pin is smoothly moved up and down.
According to the third aspect of the present invention, the shutter opening / closing mechanism can be simplified.

Hereinafter, an example of an embodiment of an empty container collection device according to the present invention will be described based on an example in which sorting means also serves as sorting means.
FIG. 1 shows an outline of an empty container collection device, where 1 is a case of the collection device, 2 is an empty container inlet opening in the front of the case 1, and the case 1 is introduced from the empty container inlet 2 In order to transfer the empty container a to the predetermined position, the transfer means 3 for transferring the empty container a to the barcode reading position, the rolling support means 4 for supporting the transferred empty container a to the barcode reading position, The vertical movement means 5 that swings the conveyance means 3 up and down, the barcode reader 6 that reads the barcode displayed on the empty container supported by the conveyance means 3 or the rolling support means 4, and the barcode reading Sorting means 7 for sorting the completed empty containers a into separate crushing means, crushing means 8, 8 'for crushing the empty containers a sorted by the sorting means 7, and a collection container 9 for storing the crushed empty containers , 9 ', Chike Printer 10 to issue a preparative, further shutter 11 or the like for opening and closing the conveying means 3 into the nearby position of the empty container inlet 2 of and the sorting unit 7 behind is equipped.

The transport means 3 for transporting an empty container (steel can, aluminum can, PET bottle, etc.) introduced from the empty container inlet 2 to a position where the barcode reader 6 can read the narrow endless belt 3a is driven by a driving pulley 3b. The driven pulley 3b is configured such that the rotation of the motor 3d is driven and rotated through power transmission means such as a belt. The surface of the endless belt 3a that constitutes the conveying surface is made of a material that is larger than the frictional resistance on the surface (aluminum material) of a roller that constitutes the rolling support means 4 described later, such as urethane resin or vinyl chloride resin. It is configured.
Further, the conveying means 3 is placed on a mounting base 14 supported via a load cell 13 on a base 12 installed in the case 1 so as to be able to swing up and down.

The conveying means 3 is supported by a shaft 15 of the drive pulley 3b on the conveying start end side so as to be rotatable by an upright frame 15 standing on a mounting base 14, and the substantially central position of the conveying means 3 in the machine length direction is attached. It is supported by the vertical movement means 5 installed on the table 14.
The up-and-down moving means 5 includes a motor 5a, an eccentric rotating plate 5b attached to the output shaft of the motor, an eccentric rotating plate 5b, and an arm 5c that connects the conveying means 3, and the arm 5c is operated by operating the motor 5a. Oscillates, whereby the conveying means 3 moves up and down on the conveying end (driven pulley 3c) side with the conveying start end (driving pulley 3b) as a fulcrum. The vertical moving means 5 is not limited to the configuration shown in the figure, and any method may be used as long as it can move the opposite side up and down using the conveyance start point side as a fulcrum.

A container detection sensor 16 and a material sensor (optical sensor) 17 are sequentially arranged at a predetermined interval on the side of the starting end side across the conveyance path of the conveyance means 3 in the conveyance direction of the conveyance means 3. Further, a magnetic sensor 18 for discriminating between a steel can and an aluminum can is disposed between the forward path surface (conveying surface) and the return path surface of the endless belt 3a of the conveying means 3.
As a result, when the inserted empty container a is a steel can, it is detected by the magnetic sensor 18, and when the input empty container is a PET bottle, it is detected by the material sensor (optical sensor) 17.
Further, a stop sensor 19 for detecting whether or not the empty container a has been transported to a predetermined position (a reading position by a barcode reader) by the transport means 3 is disposed at the end portion of the transport means 3. When the stop sensor 19 is turned on, it is determined that the empty container has been transported to a predetermined position (read position by the barcode reader), and the transport means 3 is lowered.

  The rolling support means 4 includes two rollers 4a and 4b arranged horizontally on both the left and right sides with an endless belt 3a constituting the conveying means 3 and a motor 4c for rotating the two rollers 4a and 4b.

The power transmission member 4d is formed by winding a toothed belt in a triangular shape across the toothed pulley of the motor 4c and the toothed pulley of two rollers arranged in parallel with the conveying means 3 interposed therebetween. 4a and 4b are configured to rotate in the same direction.

Further, the rollers 4a and 4b of the rolling support means 4 have a length from the position where they have passed through the detection range by the sensor to the vicinity of the end side of the conveying means 3, so that the can and the PET bottle can be stabilized. It comes to be able to support well.
The two rollers 4a and 4b constituting the rolling support means 4 are in contact with the empty container at the time of carrying by the carrying means 3.
When the conveying means 3 is tilted and lowered forward and downward by the up-and-down moving means 5, the empty container before volume reduction that has been supported by the two points of the endless belt 3a and the two rollers 4a and 4b until then. Is switched to two-point support by the two rollers 4a and 4b when the support by the endless belt 3a is lost, and is rolled by the rotation of the rollers. In the case of a volume-removed empty container, the surface friction of the rollers 4a and 4b is reduced so that the empty container does not roll even if the roller rotates.

The bar code reader 6 reads the bar code displayed on the peripheral surface of the inserted empty container a, and is suspended above the rolling support means 4 in the direction of the rolling support means. Has been. Note that a plurality (two in the drawing) of barcode readers may be fixed at a predetermined angle, but the readable range may be expanded as a swinging and sliding type. Further, the number of barcode readers 6 is not limited to a plurality, and may be one.
The reading of the barcode by the barcode reader 6 is processed by comparing the data read from the inserted empty container a with the information stored in the database of the control unit. In the apparatus corresponding to the deposit system, if the container is an empty container that is not a deposit object, the container is collected, but it is possible not to issue a ticket.

When the reading by the bar code reader 6 is completed, the empty container a is sorted out by the sorting means 7 into the crushing means 8 and 8 'according to the type.

The collection containers 9 and 9 ′ are put in and out by opening an opening / closing door provided on the front surface or side surface of the case 1.

As shown in the electric block diagram of FIG. 6, the constituent members of the above-described empty container collection device are a ROM 42, a RAM 45, a display unit 46, a key operation unit 47, a bar code reader via a bus 43 to a CPU 42 that controls each block. 6, the printer 10 and the load cell 13 are connected, and the interface 48 has a container detection sensor 16, a magnetic sensor 18, a material sensor (optical sensor) 17, a stop sensor 19, a reference position sensor 39a, an open sensor 38, a transport motor 3d, A container rotating roller motor 4c, a vertical movement motor 5a, a sorting motor 50, a crushing motor 41, and a rotary solenoid 35 are connected.
The ROM 44 stores various programs executed by the CPU 42.
The RAM 45 temporarily stores data for the CPU 42 to operate or calculate, and stores product files such as empty container materials (aluminum cans, steel cans, PET bottles, etc.), beverage manufacturers, product types, etc. is doing.
The key operation unit 47 includes a touch key for operation input, a numeric keypad for key input, and the like, and the display unit 46 is configured by a liquid crystal display or the like, and information input by the key operation unit 47 and processing contents Etc. are configured to be displayed.
The printer 10 issues a container collection ticket (certificate) to a provider who brings in an empty container to be deposited among the empty containers a put in the apparatus. The provider can exchange this for a predetermined amount of money or merchandise by taking this ticket to a predetermined shop or the like. The collected empty container material (aluminum cans, steel cans, PET bottles, etc.), beverage manufacturer, product type, quantity, etc. are all recorded in a data processing device (not shown) in the case, and the aggregated data. Can be taken out at any time.

Next, an outline of the operation of the CPU 42 shown in the electric block diagram of the above-described empty container recovery apparatus will be described based on the flowchart of FIG.
(Step 1): Turn on the power switch. Thereby, each part is reset (refer FIG. 8 (a), (b)).
(Step 2) The cylinder frame 7a of the sorting means 7 is set to the reference position by the reset operation, and the rotary solenoid 35 is driven and the shutter 11 is opened while the reference position sensor 39a is ON. When the shutter 11 is opened, the open sensor 38a is turned on. By the opening movement of the shutter 11, the restriction pin 33 rises in the vertical direction and is fitted in the groove 24 of the restriction frame 23 integrated with the sorting means 7 held at the reference position. Thereby, the sorting means 7 is fixed in a state where it cannot be mechanically swung (see FIGS. 9A and 9B). In this state, a hand or the like cannot be inserted into the subsequent crushing means 8 from the gap of the sorting means 7 or the like.
(Step 3)... When an empty container is introduced from the empty container insertion port and detected by the container detection sensor 16, the conveying means 3 is driven to start carrying in the empty container.
(Step 4)... The type of the empty container is determined by the material sensor 17 and the magnetic sensor 18 during the carry-in.

(Step 5) ... The shutter 11 is closed after a predetermined time has elapsed since the container was detected by the container detection sensor 16 in Step 3. As a result, the open sensor 38a is turned off. In a state where the shutter 11 is closed, the restriction pin 33 moves vertically downward, disengages from the groove 24 of the restriction frame 23, and the mechanism that mechanically restrains the swinging of the sorting means 7 is opened, and the sorting means is released. 7 is in a state in which it can swing in the left-right direction (see FIG. 10). When the sorting means 7 is driven and the cylindrical frame 7a swings, the regulating pin 33 moved to the lower limit position expands in a divergent shape below the groove 24 of the regulating frame 23 that swings together with the cylindrical frame 7a. It abuts on the regulation inclined portions 25 and 25 ′ to be opened, and the rise of the regulation pin 33 is restrained. As a result, the shutter 11 is not opened, and the risk that the shutter 11 opens when the sorting means 7 is driven and the operator's hand is inserted can be eliminated.
(Step 6) When the stop sensor 19 is turned on, it is determined that the container has been transported to a desired reading position (predetermined position), the transport means 3 is stopped, the empty container a is replaced with the rolling support means 4, and the The empty container a is rolled by the operation of the moving support means 4, and the barcode is read. In the case of YES, that is, in the case where the barcode is read and the container (acquisition object to be collected) permitted to be accepted, the process proceeds to Step 7;

(Step 7)... Based on the type detected in Step 4, the input empty container a is sorted left and right by the sorting means 7 (see FIGS. 11A and 11B). After the sorting is completed, the transport means 3 positioned below returns to the initial position (upper limit position) for the next empty container. The empty container is crushed by the crushing means 8 and 8 ', and stored in the collection containers 9 and 9'.
(Step 8)... After a predetermined time (timer) after returning to the reference position after the sorting means 7 is driven, the rotary solenoid 35 is driven, and the restriction pin 33 is inserted into the groove 24 of the restriction frame 23, and the shutter. 11 is opened and the empty container is waited for. The sorting means 7 is fixed again in a state where it cannot be mechanically swung again by fitting the restriction pin 33 into the groove 24 of the restriction frame 23. That is, the process returns to step 3.
(Step 9)... The rotary solenoid 35 is driven and the shutter 11 is opened in order to return the container in which the barcode could not be read in Step 6 or the container that has been read but is not a collection target product. The rotary solenoid 35 is driven by a timer.

(Step 10)... The transport means 3 is raised to transfer the empty container a from the rolling support means 4, and the transport means 3 is rotated in the reverse direction to transport the empty container to the inlet side. When the transport unit 3 rotates in the reverse direction and the transported empty container is detected by the container detection sensor 16, the driving of the transport unit 3 is stopped. This completes the process (end).
Then, the sorting means 7 operates according to the PET bottle and the aluminum can), and the empty container a on the rolling support means 4 is sorted into the crushing means 8 and 8 '. When the crushing process is completed, privilege information corresponding to the type of container is printed by the printer and a ticket is issued.

Although the above-described embodiment has a configuration in which the sorting means also serves as the sorting means, an example in which the sorting means and the sorting means are provided separately will be briefly described with reference to FIG.
FIG. 12 is a schematic diagram showing the positional relationship between the conveying means, the sorting means, the sorting means, and the crushing means, and the two rollers 4a and 4b of the rolling support means 4 in the previous embodiment are configured to be movable up and down. This rolling support means 4 is provided with a function of sorting means, and further, a shielding plate that blocks access to the space where the subsequent crushing means 8 is arranged on both sides of the rollers 4a and 4b of the rolling support means 4.

The shielding plates 51a and 51b constituting the sorting means 51 are configured to be movable up and down, and are configured to be interlocked with opening / closing movements of a shutter (not shown).

With the above configuration, the empty container is conveyed by the conveying means 3 and placed on the rollers 4a and 4b of the rolling support means 4, and the rollers 4a and 4b are rotated so that the empty container is rotated and displayed on the empty container. After the bar code is read and the sorting direction is determined, of the rollers 4a and 4b of the rolling support means 4, the roller in the direction in which the sorting is determined moves downward, whereby the empty container moves downward. Rolled to the roller side and sorted.
During the descending operation of the rolling support means 4 for performing the sorting, the crushing means 8 receives the sorted empty containers so that the shielding plate 51a or 51b of the sorting means 51 moves upward to enable the receiving. The sorting means 51 is linked to the movement of the shutter by a link mechanism. When the shutter is open, the shielding plates 51a and 51b are in the lower position, and when the shutter is closed, the shielding plates 51a and 51b are connected. 51b is positioned at the upper position.
Thereby, when the shutter is open, the space to the crushing means 8 is blocked by the sorting means 51, so that even if a hand is inserted, the crushing means 8 is not touched and safety is maintained. . The opening / closing of the sorting means is not limited to the vertical movement in the vertical direction, but may be a rotary type.

The present invention is not limited to the above-described embodiment, and can be changed without changing the gist of the present invention.
(1) The shutter opening / closing mechanism is not limited to the illustrated form, and any mechanism may be used as long as the movement of the sorting unit is restricted by the opening of the shutter and the opening of the shutter is restricted when the sorting unit is driven.
(2) In step 8, the rotary solenoid is driven and the shutter 11 is opened by raising the restriction pin 33 during the time when the cylinder frame 7a of the sorting means 7 returns to the reference position by the timer. Alternatively, the rotary solenoid 35 may be driven after the cylinder frame 7a of the sorting means 7 returns to the reference position and is detected by the reference position sensor 39a.
(3) The crushing means for reducing the volume of the empty container is not limited to the illustrated form, and any crushing means may be used as long as it can reduce the volume.
