DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The embodiment of the present invention includes the contents shown in the drawings, but is not limited thereto. In the following description of each drawing, parts common to parts already described will be given the same reference numerals and some duplicated description will be omitted. As an example of the article recovery device according to the embodiment of the present invention, a container recovery device will be described.

[0010] An item recovery device according to an embodiment of the present invention has an apparatus main body section equipped with a storage section for storing items, a loading section on which items can be placed, an outer door provided on the outside of the loading section, an inner door provided in a passage leading from the loading section to the storage section inside the apparatus main body section, an inner door drive section for driving the inner door to open and close, a detection means provided in the loading section for detecting items placed on the loading section, and a discrimination section for discriminating whether or not an item is a target for recovery based on the detection result by the detection means. The items are not limited to PET bottles, cans, and bottles, but may be any items that are subject to collection, such as milk cartons, trays, ink cartridges, items to be returned to libraries or rental stores (books, DVDs, etc.), cleaning supplies, batteries, light bulbs, etc. In other words, the container collection device is one embodiment of an item collection device.

[0011] In detail, in the article recovery device according to the embodiment of the present invention, when on standby, the outer door of the article input section is in a closed state, and the inner door provided between the article input section and the storage section so as to be freely opened and closed is in a closed state. When recovering articles, the outer door of the article input section is in an open state, and the discrimination section discriminates whether an article placed on the loading section of the article input section is an article to be recovered (e.g., an empty resin container such as a PET bottle) or not. If it is determined to be an article to be recovered (an empty container), the outer door is in a closed state, the inner door provided between the article input section and the storage section is in an open state, and the container is recovered by the storage section. In this embodiment, the container recovery device is provided with a volume reduction mechanism, and by reducing the volume of the container by the volume reduction mechanism, a large amount of reduced empty containers can be recovered in the recovery section with a specified capacity. Furthermore, when a non-recovery object such as a foreign object is put into the container insertion section, the article recovery device controls the inner door to be closed so as not to recover the non-recovery object in the container storage section in the device main body. If the non-recovery object is not removed from the placement section of the container insertion section for a predetermined time, the article recovery device maintains the inner door in the closed state and controls the drive to close the outer door. In other words, it is possible to prevent further input of the non-recovery object into the container storage section.

[0012] 1, an empty container recovery device 100 as an article recovery device according to an embodiment of the present invention has a container insertion section 110 provided at the top of a device main body 100B, and an outer door 111 provided outside the opening of the container insertion section 110. A display operation section 3 and a transmitting / receiving section 4 (communication section) are provided on the front side of the device main body 100B near the top of the outer door 111. A baggage hook 100f is also provided on the front side of the device main body 100B.

[0013] Further, below container insertion section 110, a passage communicating with container storage section 140 is provided, and an inner door 112 is provided in passage 71 from placement section 116 of container insertion section 110 to container storage section 140.

[0014] In this embodiment, the empty container recovery device 100 is provided with a volume reduction section 120 (volume reduction mechanism) between the inner door 112 and the container storage section 140. When the inner door 112 is in an open state, the volume reduction section 120 crushes the empty container A from the container input section 110 to reduce its volume, and outputs the reduced container RA to the container storage section 140 below. In addition, the main body 100B of the empty container recovery device 100 has a drawer 100C on which the container storage section 140 is placed, and is provided with a drawer handle 100e and a keyhole 100r on the front side, so that the drawer can be locked and unlocked by inserting a key into the keyhole 100r.

[0015] In addition, a translucent section 100A (translucent window) is provided on the front side of the device main body 100B, specifically, on the front side of the drawer 100C, so that the empty containers stored in the container storage section 140 can be viewed from the outside.

[0016] A handle 100g for carrying the device is provided on the side surface of the device main body 100B.

[0017] In addition, the device main body 100B has a cap insertion section 108 on the front side, and a cap passage 72 is provided from the cap insertion section 108 downward within the device main body, and the cap inserted into the cap insertion section 108 is configured to be stored in the cap storage section 145 via the cap passage 72. The cap passage 72 may have a mechanism for separating caps from items smaller than caps. Specifically, the cap passage 72 may be branched, and a mesh member may be provided at the branched portion to separate leftover cigarette butts, rainwater, etc., from the caps and store them in the cap storage section 145.

[0018] Next, the container insertion section 110 of the empty container recovery device 100 as an article recovery device will be described. Fig. 2 is a conceptual diagram of the container insertion section of the empty container recovery device. Figs. 3 and 4 are diagrams showing an example of an empty container recovery device with the outer door 111 closed and the inner door 112 closed. Figs. 5, 6 and 7 are diagrams showing an example of an empty container recovery device 100 with the outer door 111 open and the inner door 112 closed. Figs. 8 and 9 are conceptual diagrams showing an example of an empty container recovery device with the outer door 111 closed and the inner door 112 open. Note that the outer door is not shown in Fig. 9.

[0019] The container insertion section 110 of the empty container recovery device 100 of an embodiment of the present invention has a loading section 116, an outer door 111, an inner door 112, a base 118, a weighing section 7, an outer door support section S111, an inner door support section S112, an outer door drive section 5, an inner door drive section 6, a first restriction section K111, a second restriction section K112, etc.

[0020] The placement unit 116 is configured so that objects to be collected can be placed thereon. The placement unit 116 is provided with an optical sensor 9 such as a light receiving unit 9a and a light emitting unit 9b, a metal sensor, and the like. In addition, a weighing unit 7 is provided below the placement unit 116.

[0021] Furthermore, in this embodiment, the placement surface of placement unit 116 is not horizontal, but is inclined so that the container storage unit 140 side is lower than the article insertion port side (the opening side when outer door 111 is open). In other words, placement unit 116 is configured to encourage inserted articles to fall to the container storage unit 140 side (or the volume reduction unit 120 side) due to their own weight. This makes it unnecessary to provide a transport mechanism for sending articles (input items) to container storage unit 140, and makes it possible to provide a small-sized article recovery device. In addition, the surface of the placement surface of the placement section 116 is surface-treated to form an uneven portion, and has a structure that prevents the inserted article from sticking to the placement section. When the article recovery device is a container recovery device, even if the container is wet, the contact area between the container surface and the uneven surface of the placement section is relatively small, so that the surface tension due to wetting is small, and the container easily moves toward the container storage section 140. In other words, it is possible to prevent the problem that a wet container does not fall into the container storage section.

[0022] The outer door 111 is provided on the outer side of the placement unit 116. The outer door drive unit 5 drives the outer door 111 so as to be able to open and close freely. The inner door 112 is provided in the passage 71 between the placement section 116 and the volume reduction section 120. The inner door drive section 6 drives the inner door 112 to open and close freely. As shown in Figs. 5 and 7, the inner door 112 is provided with a guide section 112D that guides the placement state of the empty container. The guide section 112D is provided at a position that is exposed and visible from the device main body. The guide section 112D displays information to guide the user to place the item (empty container such as a PET bottle) in a specified orientation and at a specified position (for example, 350 ml, 500 ml, 2000 ml, etc.). The guide section 112D may be a recess, a protrusion, a sticker, an LED display, an LCD, etc. provided on the surface of the inner door 112. The article recovery device may also include a determination unit that uses a detection sensor such as an imaging unit to determine whether an article is correctly placed at the placement position indicated by the guide unit 112D. Also, a detection unit such as an imaging process or an optical sensor can provide a notification when the placement orientation and position are incorrect.

[0023] In this embodiment, the empty container recovery apparatus 100 has a base 118, and this base 118 has outer door support parts S118, S111 that support the outer door 111 and the outer door drive unit 5. In detail, the outer door drive unit 5 and a rotation shaft C111 are provided at the upper end parts of the two outer door support parts S118, and a fan-shaped outer door support part S111 is rotatably provided on the rotation shaft C111, and the outer door 111 is supported by the fan-shaped outer door support part S111. One of the two rotation shafts C111 is connected to the rotation shaft of the motor of the outer door drive unit 5. The sector-shaped outer door support portion S111 is provided with a hole S111h through which the rotation shaft C112 of the inner door 112 passes.

[0024] The measuring unit 7 is disposed between the base 118 and the placement unit 116 and supports the placement unit 116 .

[0025] In addition, the inner door 112 is configured to guide an empty container placed on the placement unit 116 to the volume reducing unit 120 in an open state. In this embodiment, the inner door drive unit 6 and the inner door 112 are supported by an inner door support unit S112 that is disposed on the weighing unit 7 and extends from between the weighing unit 7 and the placement unit 116. The inner door drive unit 6 is provided with a rotation shaft C112 for the inner door 112, and the inner door 112 is provided on the rotation shaft C112. By opening the inner door 112, the collection target can be guided to the container storage unit 140 in the device main body. In addition, the inner door support unit S112 has a hole S112h through which the rotation shaft C111 passes.

[0026] That is, the outer door drive unit 5 and the outer door 111 are supported by the outer door support part S111 of the base 118, and the placement part 116 is provided on the upper part of the weighing part 7 arranged on the base 118, so that the weighing part 7 can measure the mass of the collection object and the like placed on the placement part 116 with high accuracy. In detail, since the outer door 111 and the outer door drive unit 5 are not supported on the weighing part 7, the weighing part 7 is structured to be less susceptible to the effects of vibrations of the outer door 111 and the outer door drive unit 5, and the mass of the collection object on the placement part 116 can be measured with high accuracy.

[0027] Furthermore, the outer door 111 of the empty container recovery device 100 as the article recovery device according to the embodiment of the present invention is configured to be movable between an open position exposing the mounting section 116 and a closed position covering the mounting section 116, and when the outer door 111 is closed, the outer door 111 is configured to be movable from the open position to a closed position toward the mounting section 116. That is, since the outer door 111 is configured to move from the open state toward the mounting section 116 to close, for example, when a user's hand, arm, or the like is caught between the outer door 111 and the mounting section 116, the weighing value by the weighing section fluctuates, and the control section detects the fluctuation, so that it is possible to easily detect that the user's hand, arm, foreign object, or the like is caught between the outer door 111 and the mounting section 116.

[0028] Moreover, in the empty container recovery device 100 as the article recovery device according to the embodiment of the present invention, the outer door 111 is provided with a first limiting portion K111 that limits the movement of the inner door 112. The inner door 112 is provided with a second limiting portion K112 that limits the movement of the outer door 111. The first limiting portion K111 and the second limiting portion K112 provide a mechanism for limiting both the outer door 111 and the inner door 112 from being in an open state. In other words, the empty container recovery device 100 has a first limiting section K111 provided on the outer door 111 and a second limiting section K112 provided on the inner door 112, so that with a simple mechanical structure, it is possible to limit the opening and closing operation of each door depending on the opening and closing state of the outer door 111 and the inner door 112, respectively.

[0029] Moreover, the first limiting unit K111 of the empty container recovery device 100 as an article recovery device is configured to respond to the movement of the outer door 111. The second limiting unit K112 is configured to respond to the movement of the inner door 112. Moreover, the empty container recovery device 100 is configured such that when the outer door 111 is in an open state, the first limiting unit K111 limits the movement of the inner door 112, and when the inner door 112 is in an open state, the second limiting unit K112 limits the movement of the outer door 111. In detail, in this embodiment, the empty container recovery device 100 is configured so that when the outer door 111 is open, the inner door 112 remains in the closed state and is restricted from opening. That is, when the outer door 111 is open and an inserted object is placed on the placement section 116, the inner door 112 is in the closed state and does not open, and is configured so that the object placed on the placement section 116 is not stored in the container storage section 140 in the device main body 100B regardless of whether the object is a collection object or a non-collection object. That is, in this state, the object (a collection object or a non-collection object) is in contact with the inner door 112, and the inner door 112 is configured to also serve as a part of the placement section.

[0030] The first limiting part K111 and the second limiting part K112 are configured to have their movement paths overlapped. In the present embodiment, the empty container recovery device 100 has a structure in which, when one of the first limiting part K111 and the second limiting part K112 limits the movement of the other, the first limiting part K111 and the second limiting part K112 are adjacent to each other with a slight gap in an arc shape. In detail, in the present embodiment, the first limiting part K111 is formed in a substantially fan shape. The first limiting part K111 has a convex arc-shaped part K111a and a concave part K111b. The second limiting part K112 is formed in a substantially fan shape. In detail, the second limiting part K112 has a convex arc-shaped part K112a and a concave part K112b.

[0031] As shown in Figures 5 and 6, when the outer door 111 is open and the inner door 112 is closed, and the first limiting portion K111 limits the movement of the second limiting portion K112, the convex arc-shaped portion K111a of the first limiting portion K111 and the concave portion K112b of the second limiting portion K112 are adjacent to each other with a slight gap between them in an arc shape. That is, in an embodiment of the present invention, as described above, when the outer door 111 is in the open state, the inner door 112 is in the closed state, and the first limiting portion K111 restricts the movement of the second limiting portion K112, so that the inner door 112 remains in the closed state and does not open.

[0032] Also, as shown in Figures 8 and 9, when the inner door 112 is open and the outer door 111 is closed, and the second limiting portion K112 limits the movement of the first limiting portion K111, the convex arc-shaped portion K112a of the second limiting portion K112 and the concave portion K111b of the first limiting portion K111 are adjacent to each other with a slight gap between them in an arc shape.

[0033] In other words, in the empty container recovery device as an item recovery device of an embodiment of the present invention, when the outer door 111 is closed and the inner door 112 is open, the second limiting portion K112 restricts the movement of the first limiting portion K111, so that the outer door 111 remains closed and does not open.

[0034] In this embodiment, the empty container recovery device 100 may have a prohibiting means for prohibiting the movement of one or both of the first limiting part K111 and the second limiting part K112. In detail, the prohibiting means has, for example, a solenoid. This solenoid has, for example, a structure in which a metallic movable pin (plunger) is arranged in a coil, and when the coil is not energized, the movable pin (plunger) is arranged in a position protruding from the coil end by a biasing part, and is configured so that when the coil is energized, the movable pin moves into the coil. For example, as a prohibition means capable of prohibiting the movement of the outer door 111 from the closed state to the open state, a movable pin (plunger) of a solenoid for the outer door may be configured to be able to engage with a hole provided in the first limiting part K111, and the control part controls the movable pin to engage with the hole when the first limiting part K111 is to be maintained in the closed state and movement to the open state is to be prohibited, and to disengage the movable pin when movement is not to be prohibited. In other words, the prohibition means can prohibit the movement of the first limiting part K111 from the closed state to the open state with a simple structure. As a prohibition means capable of prohibiting the movement of the inner door 112 from the closed state to the open state, a movable pin (plunger) of the solenoid for the inner door may be configured to be engageable with a hole provided in the second limiting part K112, and the control part controls the movable pin to engage with the hole when the second limiting part K112 is to be maintained in the closed state and movement to the open state is to be prohibited, and to disengage the movable pin when the movement is not to be prohibited. In other words, the prohibition means can prohibit the movement of the second limiting part K112 from the closed state to the open state with a simple structure. Moreover, the empty container recovery device 100 as an article recovery device according to the embodiment of the present invention has a waiting section AA where the outer door 111 waits in the closed position, as shown in Figures 5 and 9. The waiting section AA is provided at a position where the outer door 111 does not touch the placement section 116, and functions as a stopper for the outer door 111.

[0035] Fig. 10 is a schematic side view showing an example of a volume reduction unit of an empty container recovery device as an article recovery device according to an embodiment of the present invention, and Fig. 11 is a schematic plan view showing an example of a volume reduction unit of an empty container recovery device. The volume reducing section 120 has a structure in which a pair of rotating shafts 811, 911 are rotatably supported by two substantially plate-shaped supporting members.

[0036] Further, a feed mechanism 50 is provided above the volume reduction section 120, and a rotating shaft 51 of the feed mechanism 50 is rotatably supported by the above-mentioned substantially plate-shaped support member. The feed mechanism 50 has a plurality of blade portions 52 (made of metal, resin, etc.) as paddles on the rotating shaft 51. As the rotating shaft 51 rotates, the blade portions 52 of the feed mechanism 50 rotate around the rotating shaft 51 as the center of rotation, and guide the empty container A to the volume reduction section 120.

[0037] In addition, at the top of the volume reduction section 120, plate-shaped regulating members 61 and 62 are provided, inclined in opposite directions, so as to guide the empty container A toward the center of the volume reduction section 120, thereby regulating the empty container A from moving to other locations.

[0038] The rotating shafts 811, 911, 51 are arranged parallel to each other at a predetermined interval. On each of the pair of rotating shafts 811, 911, compression rollers 81, 91 each having a blade surface 81k or a blade surface 91k on both axial sides and spacers s each having a smaller diameter than the compression rollers 81, 91 and a slightly thicker thickness than the compression rollers 81, 91 are alternately arranged in parallel along the axial direction. The outer periphery of the compression roller provided on one rotating shaft is disposed between the compression rollers provided on the other rotating shaft, and is disposed at a predetermined distance LP from the spacer s provided between the compression rollers provided on the other rotating shaft. In addition, the distance LP between the spacer s provided on the rotating shaft 811 and the compression roller 91 provided on the rotating shaft 911 facing the spacer s is set to be smaller than the maximum outer diameter LAg of the body Ag of the empty container A.

[0039] 10 and 11, a gear 811m is provided at one end of the rotating shaft 811, and is configured to mesh with a gear 911m provided at one end of the rotating shaft 911. These rotating shafts 811, 911, 51 are rotated by a drive motor (not shown). When driven, the rotating shafts 811 and 911 rotate in opposite directions, and an empty container A placed in the center is compressed by the compression rollers 81 and 91, and the reduced-volume empty container is output downward.

[0040] The peeling units 31, 32 are configured to peel off the containers, the volume of which has been reduced by the compression rollers 81, 91 of the volume reducing unit 120, from the compression rollers 81, 91.

[0041] As shown in FIG. 11, the length LAb (neck length) of the neck Ab of an empty container A such as a plastic bottle is the length from the tip Ac on the opening Ah side to the neck ring or the base of the neck.

[0042] An empty resin container A such as a PET bottle is formed with a neck Ab that is thicker than other parts, specifically, the shoulder and body Ag. For example, when the neck Ab of an empty container A is separated from other parts and becomes a lump smaller than a standard, the empty container may be deemed ineligible for recycling by a recycler. The volume reduction unit 120 reduces the volume of the relatively thick and heavy neck Ab to a flat shape larger than the above standard so that the empty container can be recycled without being separated from the shoulder and body Ag.

[0043] Further, the distance LT between the spacer s provided on the rotating shaft 911 and the spacer ws(s) provided on the rotating shaft 811 is longer than the outer diameter of the neck portion Ab of the empty container. Further, the distance LC from the inner surface of the support member 871 to the compression roller 81 arranged on the side surface of the rotating shaft 811 is configured to be longer than the length LAb of the neck portion Ab of the empty container A. In this embodiment, the distance LC is set to be longer than the axial length of the spacer ws(s) arranged on the side of the rotating shaft 811. The axial length (thickness) of the spacer ws(s) is set to be approximately twice as long as the axial length Ls of the other spacers. That is, in order to prevent the neck portion Ab of the empty container A from being separated from the shoulder portion Af and the body portion Ag, the compression roller on the support member 871 side provided on the rotating shaft 811 is positioned at a predetermined distance from the side surface of the support member 871. That is, the volume reduction unit 120 is structured so that, when reducing the volume of a container, the neck portion Ab of the empty container A is reduced in volume while remaining connected to the shoulder portion and the body portion Ag.

[0044] In this embodiment, the axial thickness L1 of the compression rollers 81, 91 is shorter than the length LAb of the neck portion Ab of the empty container A. For example, even if an empty resin container A such as a PET bottle is placed upside down, specifically, even if the tip portion Ac of the empty container A where the opening Ah is formed is positioned on the side of the substantially plate-shaped support member 871, the neck portion Ab of the empty container A is not separated from the shoulder portion or body portion Ag when the container is reduced in volume.

[0045] Next, an example of the electrical configuration of the empty container recovery device 100 as an article recovery device according to an embodiment of the present invention will be described. 12, the article recovery device (empty container recovery device 100) has a control unit 1 (CPU), a memory unit 2, a display operation unit 3, a transmission / reception unit 4, an outer door drive unit 5, an inner door drive unit 6, a weighing unit 7, a metal sensor 8, an optical sensor 9, a door position sensor 10, a door lock unit 11, a volume reduction drive unit 15, etc. Each component is electrically connected by a signal line or the like.

[0046] The control unit 1 (CPU) comprehensively controls each component of the article recovery device (empty container recovery device 100). The control unit 1, for example, executes a control program to realize the functions according to the present invention in a computer.

[0047] The storage unit 2 is a storage device such as a RAM or a ROM. The storage unit 2 stores control programs and the like. The storage unit 2 also stores characteristics of empty containers to be collected. The characteristics of the empty containers include, for example, the range of container mass and whether or not the container is made of resin material.

[0048] The display operation unit 3 performs a predetermined display under the control of the control unit 1. The display operation unit 3 also outputs a signal corresponding to an operation by a user or the like to the control unit 1. The display operation unit 3 is, for example, a touch panel display device.

[0049] The transmitting / receiving unit 4 is a transmitting / receiving device that communicates with non-contact IC cards, IC tags, etc., and performs predetermined communication under the control of the control unit 1. Also, under the control of the control unit 1, the transmitting / receiving unit 4 performs predetermined communication with other terminal devices (computers) via a wireless communication path or a wired communication path.

[0050] The outer door drive unit 5 is a motor or the like for opening and closing the outer door 111, and is drive-controlled by the control unit 1.

[0051] The inner door driving unit 6 is a motor or the like for opening and closing the inner door 112, and is controlled by the control unit 1 to drive the inner door in an open or closed state.

[0052] The weighing unit 7 weighs the mass of an empty container or an object not to be collected placed on the placement unit 116 of the container insertion unit 110. The weighing unit 7 is a weighing device such as a load cell. The weighing unit 7 is also used as a sensor that detects remaining drink in a container placed on the placement unit 116 of the container insertion unit 110, thereby determining whether or not the container can be collected. The weighing unit 7 is also configured to be able to determine the total weight of the containers stored in the container storage unit 140 by accumulating the weight values ​​of the containers that have been determined to be collectable. This function eliminates the need to provide a weighing unit in the container storage unit 140, making it possible to ensure a container storage unit 140 with a large capacity, and allowing the weighing unit 7 itself to be made small. Since the object to be weighed is relatively small, there is no need to provide a large weighing unit 7.

[0053] The metal sensor 8 detects whether an object placed on the placement unit 116 of the container input unit 110 is metallic or non-metallic. In this embodiment, when the metal sensor 8 detects that the object placed on the placement unit 116 is metallic, the control unit 1 determines that the object placed on the placement unit 116 is a non-collection target object.

[0054] The optical sensor 9 also has a light receiving unit 9a that receives light from a light emitting unit 9b provided in the container insertion unit 110. The optical sensor 9 is configured to include, for example, a polarizing plate and receive light through the polarizing plate, and is configured to be able to detect empty containers to be collected by detecting polarized light that has passed through translucent empty containers such as PET bottles. The control unit 1 detects light received through a translucent empty container placed on the loading section of the container insertion section using an optical sensor 9, and determines whether or not the empty container is a collection target based on the detection signal from the optical sensor 9.

[0055] The article recovery device is provided with the above-mentioned sensors around the placement unit for determining whether or not recovery is required. For example, in a conventional recovery device, an article is taken into the device, and it is determined whether or not it is a recovery target, and non-recoverable objects are discharged from a discharge port different from the input port. Since a determination unit is provided in the device, it is necessary to provide a discharge port. On the other hand, the article recovery device according to the embodiment of the present invention is configured such that it is not necessary to take in the objects to be recovered because the loading section, which corresponds to the inlet of the device, is provided with sensors that determine whether or not recovery is necessary. Therefore, it is not necessary to provide an outlet, and a small-sized article recovery device can be provided.

[0056] The door position sensor 10 detects the positions of the outer door 111 and the inner door 112, and outputs a signal related to the positions of the outer door 111 and the inner door 112 to the control unit 1. The control unit 1 controls the open / closed state of the outer door 111 and the inner door 112 based on the signal.

[0057] The door lock unit 11 has a locking device such as a solenoid, and under the control of the control unit 1, locks the movement of the outer door 111 and the inner door 112 as necessary.

[0058] The control unit 1 has a first drive control unit 101, a second drive control unit 102, a third drive control unit 103, a fourth drive control unit 104, a notification processing unit 105, etc. The control unit 1 realizes the functions of each drive control unit in the article recovery device (empty container recovery device) as a computer by, for example, executing a control program.

[0059] When collecting a container, the first drive control unit 101 controls the outer door 111 to be in an open state by the outer door drive unit 5. The control to open the outer door 111 includes not only automatically opening the outer door 111 but also, for example, simply releasing the lock and opening the door itself by the user (=manually) (following a notification / display requesting that the door be opened).

[0060] When an item to be collected is placed on the placement section 116, the second drive control section 102 controls the outer door drive section 5 and the inner door drive section 6 to close the outer door 111 and open the inner door 112, thereby collecting the container in the container storage section 140.

[0061] When the detection unit detects that the item is not to be collected, and the non-collection item is not removed for a predetermined period of time or more, the third drive control unit 103 controls the outer door drive unit 5 and the inner door drive unit 6 to maintain the inner door 112 in a closed state and to close the outer door 111.

[0062] When the outer door 111 is moved from the open position to the closed position by the outer door drive unit 5, the fourth drive control unit 104 controls to stop the movement of the outer door 111 from the open position to the closed position when the weighing unit 7 detects a change in the measurement value. That is, when the outer door 111 is moved from the open position to the closed position, the control unit 1 controls to stop the movement of the outer door 111 from the open position to the closed position when the weighing unit 7 detects a change in the measurement value, thereby making it possible to prevent the user's hand, arm, foreign object, etc. from being caught between the outer door 111 and the placement unit 116, reducing the load on the outer door drive unit 5 and preventing breakdowns.

[0063] When a non-collection target object is detected by the detection unit, the notification processing unit 105 performs notification processing to remove the non-collection target object. As the notification processing, for example, a screen is displayed on the display unit of the display operation unit 3 to prompt the user to remove the non-collection target object.

[0064] Next, an example of the operation of the article recovery device (empty container recovery device 100) according to the embodiment of the present invention will be described with reference to FIG.

[0065] In step ST1, the empty container recovery device 100 is in a standby state. When the control unit 1 receives a signal from the transmitting / receiving unit 4 (communication unit) or the display operation unit 3, it performs processing according to the signal. In addition, the control unit 1 performs processing to display, for example, "Please touch your card (membership card, etc.)" on the display unit of the display operation unit 3. The card (membership card, etc.) is, for example, a contactless IC card for members.

[0066] In step ST2, the control unit 1 determines whether the outer door opening condition is met, and if the outer door opening condition is met, the process proceeds to step ST3. For example, if the empty container collection start button is operated on the display operation unit 3 such as a touch panel as the outer door opening condition, the process proceeds to step ST3. Note that the process may proceed to step ST3 on the condition that the membership card held by the user communicates with the transmission / reception unit 4 and the user is correctly authenticated (outer door opening condition). Examples of the membership card include a contactless IC card, a magnetic card, a card with a barcode or two-dimensional code printed on it, a display device displaying a barcode or two-dimensional code, a smartphone or a mobile phone with a membership card function, and the like. Furthermore, in step ST2, the control unit 1 performs a process of displaying on the display unit of the display operation unit 3, for example, "Please insert a container."

[0067] In step ST3, the control unit 1 performs an outer door opening process. In detail, the control unit 1 releases the door lock unit of the outer door 111, and performs drive control to move the outer door 111 to an open state by the outer door drive unit 5.

[0068] In step ST4, various detection processes are performed by the weighing unit 7, metal sensor 8, optical sensor 9, etc. to detect the mass, material, presence or absence of contents, etc. of the object placed on the placement unit 116, and a signal indicating the detection result is output to the control unit 1.

[0069] In step ST5, the control unit 1 determines whether the outer door closing condition is satisfied. In detail, if it is determined that the object placed on the placement unit 116 is a collection target object, the process proceeds to step ST6, and otherwise (if it is a non-collection target object such as a foreign object), the process proceeds to step ST51. In addition, even if the control unit 1 determines as a result of the detection process that the item placed on the placement unit 116 is an empty container, it may determine that the container contains a foreign object, for example, when it detects that there is a predetermined amount of leftover liquid in the container.

[0070] In step ST6, the control unit 1 performs an outer door closing process. In detail, the control unit 1 controls the driving of the outer door driving unit 5 so as to close the outer door.

[0071] In step ST7, the control unit 1 determines whether or not a change in the weighing value has been detected by the weighing unit 7, and if a change in the weighing value has been detected, proceeds to processing of step ST8; otherwise, it continues the detection processing of step ST7 until the change in the weighing value subsides.

[0072] In step ST8, the control unit 1 determines whether the inner door opening condition is satisfied, and if the inner door opening condition is not satisfied as a result of the determination, the process proceeds to step ST13, and if the inner door opening condition is satisfied, the process proceeds to step ST9. The inner door opening condition is, for example, that the object placed on the placement unit 116 is a collection target object.

[0073] In step ST9, the control unit 1 performs an inner door opening process. In detail, the control unit 1 controls the inner door driving unit 6 to drive the inner door 112 to the open state. In step ST9, the control unit 1 performs a process to display, for example, "Recycling in progress, xx containers" on the display unit of the display operation unit 3. As will be described later, in the case of continuous container insertion, the control unit 1 performs a process to count up the number of containers and display it on the display unit. In addition, in the case of non-continuous insertion, the control unit performs a process to display "1 container" on the display unit.

[0074] In step ST10, the control unit 1 performs an inner door closing process. In detail, the control unit 1 controls the inner door drive unit 6 to close the inner door 112. When the inner door 112 is closed, the placement unit and the volume reduction unit are separated (partitioned). Then, the process proceeds to step ST11.

[0075] In step ST11, the control unit 1 performs an outer door opening process. In detail, the control unit 1 controls the outer door drive unit 5 to open the outer door 111. The outer door 111 is in the open state, and the next container can be inserted. In step ST11, the control unit 1 performs a process of displaying, for example, "Please insert the next container. If not, touch the screen" on the display unit of the display operation unit 3. As will be described later, when the operator (user, etc.) touches the screen of the display operation unit 3, this is regarded as a declaration of termination.

[0076] In step ST12, the control unit 1 performs a volume reduction process. In detail, the control unit 1 performs a process of reducing the volume of the empty container A by the volume reduction unit 120. Note that the volume reduction process in step ST12 does not have to be performed. Also, it is possible to select whether or not to reduce the volume of the container as necessary.

[0077] In step ST13, the control unit 1 determines whether or not a new article has been placed on the placement unit based on signals from the sensors. If an article is detected, the process proceeds to step ST4, and if an article is not detected, the process proceeds to step ST14. As described above, by proceeding to step ST4, it is possible to perform continuous container insertion processing. Specifically, since a new container can be inserted into the placement section while the volume reduction section is performing volume reduction processing on an empty container, the detection processing by the sensor (detection section) of the placement section and the volume reduction processing by the volume reduction section can be performed in parallel. In other words, the item recovery device can efficiently reduce the volume of empty containers. Furthermore, even if continuous loading processing is not performed, the inner door 112 is closed during volume reduction processing, and the placement section and the volume reduction section 120 are separated (partitioned), so even if fragments of containers, etc. are scattered due to the volume reduction processing by the volume reduction section, the fragments will not reach the placement section.

[0078] In step ST14, the control unit 1 determines whether or not an end operation has been detected, and if an end operation has been detected, the process proceeds to step ST1, otherwise the process proceeds to step ST15. In detail, the control unit 1 performs a process of displaying, for example, "Please insert the next container. If not, please touch the screen" on the display unit of the display operation unit 3, and if the end of the operation is detected by touching the screen, the process proceeds to the above step ST1.

[0079] In step ST15, the control unit 1 determines whether the volume reduction process of the container by the volume reduction unit 120 has been completed, and if so, proceeds to the process of step ST1, and if not, proceeds to the process of step ST13. In detail, in step ST15, the control unit 1 starts timing from the outer door open state of ST11, and if a predetermined time has elapsed, it determines that there is no next container, and automatically proceeds to the process of step ST1, which is the standby state described above.

[0080] In step ST51, the control unit 1 determines whether the outer door closing condition is met in step ST5, and if it determines that the item placed on the placement unit 116 is not a collection target item, it determines whether a predetermined time, for example, about 30 seconds to 1 minute, has elapsed.If the result of the determination is that the predetermined time has elapsed, it proceeds to processing in step ST52, and if the predetermined time has not elapsed, it enters a standby state until the predetermined time has elapsed.

[0081] In steps ST52 and ST53, the control unit 1 performs an outer door closing process to close the outer door 111 while maintaining the closed state of the inner door 112. In detail, the control unit 1 controls the driving of the outer door driving unit 5 to bring the outer door 111 into the closed state.

[0082] In step ST54, the control unit 1 performs a notification process. In detail, when a non-recovery object is placed on the placement section 116 of the container input section 110 and the outer door 111 is in a closed state, the control unit 1 performs a process of notifying the user that the non-recovery object remains in the input section in the volume reduction section and has not been collected, and a process of notifying the user to remove the non-recovery object from the placement section 116. The notification process includes a process of displaying on the display section of the display operation section 3, a process of sounding a predetermined notification sound, and a process of illuminating a light-emitting element such as an LED. Then, the process proceeds to step ST1. The notification process of the control unit 1 may also include issuing the notification to an external terminal device (not shown). The external terminal device may be, for example, a POS terminal installed in a store, a portable terminal device carried by a store clerk or a system administrator, or a higher-level server. The control unit 1 may issue the notification (such as displaying a pop-up screen, turning on a lamp, or outputting a sound) to the external terminal device via a wireless or wired communication path using the transmission / reception unit 4. The control unit 1 may also output an error so that each terminal device can issue the notification directly, or may output an error to a higher-level server, and the POS terminal or the like may issue the notification via the server. The control unit 1 may also issue other error information (such as full detection, a sign to replace consumable parts, or other failure errors) in the same manner. The cases where the container collector is identified after the processing of step ST54 and where the container collector is not identified will be described in detail. When identifying the person who collects the items, when a store clerk who has received the notification holds up or touches (or brings close) an IC card with identification information for the administrator (the identification information for the administrator is stored in the memory section of the IC card) over or near the transmitter / receiver section 4, the control section performs control to open the outer door 111 after confirming that authentication processing for the administrator has been performed correctly. With the outer door 111 in the open state, the store clerk can remove the non-collectable items. In other words, by giving only a limited number of people the authority to open the outer door when an error occurs, it is possible to prevent further insertion of foreign objects or mischief. If the collector is not specified, even if the outer door 111 is closed in ST52 and ST53 and foreign objects cannot be inserted, when the transmitter / receiver 4 reads out the identification information from the IC card or the like, the control unit 1 may perform a process to open the outer door 111 regardless of whether the person is a manager or not. This allows a customer who wants to use the article recovery device to remove the non-recovery objects. In other words, it is possible to prevent a loss of opportunity, in that the article recovery device cannot be used until a store clerk or the like comes and removes the non-recovery objects.

[0083] <Empty container storage section> Next, an example of the container storage section 140 of the empty container recovery device according to the embodiment of the present invention will be described with reference to Fig. 14. In detail, Fig. 14(a) is a perspective view showing an example of the container storage section, and Fig. 14(b) is a view showing an example of the container storage section to which a container storage bag and a cap storage bag are attached.

[0084] The container storage section 140, which is removably attached to the lower part of the device main body 100B of the empty container recovery device 100, is an approximately rectangular container with an opening at the top and a bottom at the bottom, as shown in Figure 14(a), and is provided with a translucent section 140a or a semi-translucent section on the front side, so that the inside of the container storage section 140 can be easily viewed from the outside.

[0085] 14, a large container storage bag is removably mounted in container storage section 140 having an opening at the top. In this embodiment, container storage section 140 having a substantially rectangular opening at the top is provided with an insertion port 140b for fixing container storage bag BB near the top end of the side surface. In this embodiment, slit-shaped insertion port 140b is formed in the center of an oval elastic member.

[0086] When attaching the container storage bag BB to the container housing part 140, the container storage bag BB is stored in the center of the container housing part 140, and the upper end of the container storage bag BB is folded outward and inserted into the insertion opening 140b. In other words, by inserting the container storage bag BB into the slit-shaped insertion opening 140b of the elastic member, the bag is engaged with the slit, and the container storage bag BB is fixed to the container housing part 140.

[0087] For example, when removing the container storage bag BB from the container storage section 140 after collecting multiple containers in the container storage bag BB, the container storage bag BB can be pulled from the insertion port 140b with a force greater than or equal to a predetermined force, thereby disengaging the bag and allowing it to be easily removed.

[0088] In this embodiment, a cap storage portion is provided in a portion of the container storage portion 140. In detail, a cap storage bag BS is disposed in one corner of the container storage portion 140. The cap storage bag BS preferably has, for example, two handle portions. The container storage unit 140 has an engagement portion such as a hook near the upper part of the side of the corner. The container storage unit 140 can easily store caps with a simple structure by engaging the handle portion of the cap storage bag BS with this engagement portion and locating the opening of the bag near the exit of the cap passage.

[0089] 14, the cap storage part is supported within the container storage part 140. The above configuration can be easily achieved by engaging the handle part BSa of the cap storage bag BS serving as the cap storage part with an engaging part 140f such as a hook near the upper part of the outer surface of the container storage part 140. Also, since the cap storage part is provided within the container storage part 140, space saving can be achieved.

[0090] FIG. 15 is a perspective view showing another example of the container insertion part of the empty container recovery device according to the embodiment of the present invention. In the example shown in FIG. 15, the empty container recovery device has a container insertion part 110B with a manual drawer structure, and a placement part 116B for placing an empty container on the drawn part is provided. When placed on this placement part 116B, the control part of the empty container recovery device determines whether or not the empty container is a collection target based on signals from the various sensors (weighing part, optical sensor, metal sensor, etc.) described above. If it is a collection target, the manual container insertion part 110B can be closed, and when the part drawn out by the user is closed, the inner door 112B is opened, and the collection target is recovered into the device main body. On the other hand, if it is a non-collection target, the manual container insertion part 110B is locked by a locking mechanism such as a solenoid and is not closed. When the non-collection target is removed from the placement part by the user, the locking mechanism is unlocked, and the manual container insertion part 110B can be closed.

[0091] In the embodiment of the present invention, the outer door is configured to close by rotating from top to bottom, but the closing direction and movement method are not limited, and the closing direction may be, for example, from bottom to top, right to left, left to right, or front to back, and the movement method may be rotation, translation, folding, a detachable lid, double door, etc. The inner door is also similar to the outer door. At least the opening and closing of the outer door is not limited to drive control, and may be, for example, manual.

[0092] As described above, the empty container recovery device 100 as an article recovery device according to an embodiment of the present invention has an apparatus main body 100B equipped with a storage section (container storage section 140) for storing articles, and a container input section 110. The container input section 110 has a placement section 116 on which articles can be placed, an outer door 111 provided on the outside of the placement section 116, and an inner door 112 provided in a passage 71 leading from the placement section 116 to the storage section (container storage section 140) in the apparatus main body 100B. In addition, the empty container recovery device 100 as an article recovery device has an outer door drive section 5 that drives the outer door 111 to open and close, and an inner door drive section 6 that drives the inner door 112 to open and close. In addition, the control unit 1 of the empty container recovery device 100 is provided on the loading section and has a detection means (such as a weighing unit 7) that detects items placed on the loading section, and a discrimination unit (control unit 1) that determines whether or not an item is eligible for recovery based on the detection result by the detection means. In other words, it is possible to provide a small-sized empty container recovery device with a simple structure that can determine whether an inserted item is a recovery target without having to take the item into the device main body 100B of the empty container recovery device 100.

[0093] Furthermore, the detection means of the empty container recovery device 100 as an article recovery device according to an embodiment of the present invention is provided on the placement section 116 of the container insertion section 110, and has a mass detection section (weighing section 7) that detects the mass of an object placed on the placement section 116. The discrimination section of the control section 1 discriminates whether or not the object placed on the placement section 116 is an object to be recovered, based on the mass of the object placed on the placement section 116 detected by the mass detection section (weighing section 7). In detail, for example, if the mass of an object placed on the mounting section 116 is within a predetermined range for the mass of empty containers of objects to be collected, the discrimination section determines that the object placed on the mounting section 116 is an object to be collected, closes the outer door, opens the inner door, and stores the empty container to be collected inside the main body of the device; if the mass is outside that range, the discrimination section determines that the object is not to be collected, and performs control to keep the inner door closed so as not to collect the object into the main body of the device, and to keep the outer door open. In other words, based on the mass of the object placed on the mounting section 116, if the object placed on the mounting section 116 is not to be collected, it is not stored in the device main body section 100B, and only the object to be collected can be stored in the container storage section 140 within the device main body section 100B, thereby providing a small-sized empty container collection device with a simple structure.

[0094] In addition, the control unit 1 of the empty container recovery device 100 as an item recovery device in an embodiment of the present invention controls the drive of the inner door drive unit 6 to maintain the inner door 112 in a closed state when the discrimination unit determines that the item is not a recovery item, and controls the drive of the inner door drive unit 6 to open the inner door 112 when the discrimination unit determines that the item is a recovery item. In other words, if the inserted item is not a collection item, it is not stored in the device main body 100B, and only the collection item can be stored in the container storage section 140 within the device main body 100B, making it possible to provide a small-sized empty container collection device with a simple structure.

[0095] Although the embodiments of the present invention have been described in detail above with reference to the drawings, the specific configurations are not limited to these embodiments, and the present invention also includes design changes and the like that do not deviate from the gist of the present invention. In addition, the embodiments shown in the above-mentioned drawings can be combined with each other as long as there is no particular contradiction or problem in the purpose, configuration, and the like. Furthermore, the contents of each drawing may be independent embodiments, and the embodiment of the present invention is not limited to one embodiment obtained by combining the drawings.

[0096] The empty container recovery device according to the embodiment of the present invention described above is equipped with a volume reduction section (volume reduction mechanism) that reduces the volume of empty containers, but is not limited to this embodiment. For example, it may not be equipped with a volume reduction mechanism and the empty containers that are the recovery objects inserted may be recovered in their original state.

[0097] In the above-described embodiment, the empty container recovery device recovered empty containers such as PET bottles, but it may also be configured to recover aluminum cans, steel cans, etc., or it may be a device that can be used to recover PET bottles, aluminum cans, and steel cans.
