As the notification process, for example, a screen display prompting the display unit of the display operation unit 3 to eliminate the non-collected object is performed.

Next, an example of the operation of the article collection device (empty container collection device 100) according to the embodiment of the present invention will be described with reference to FIG. 13 and the like.

In step ST1, the empty container collecting device 100 is in the standby state. When the control unit 1 receives a signal from the transmission / reception unit 4 (communication unit) or the display operation unit 3, the control unit 1 performs processing according to the signal. Further, the control unit 1 performs a process of displaying, for example, "Please touch a card (membership card or the like)" on the display unit of the display operation unit 3. The card (membership card, etc.) is, for example, a contactless IC card for members.

In step ST2, the control unit 1 determines whether or not the outer door opening condition is satisfied, and if the outer door opening condition is satisfied, proceeds to the process of step ST3. As a condition for opening the outer door, for example, when the display operation unit 3 such as a touch panel operates the empty container collection start button or the like, the process proceeds to step ST3. The process of step ST3 may proceed on the condition that the membership card possessed by the user and the transmission / reception unit 4 communicate with each other and the personal authentication is correctly performed (condition for opening the outer door). Membership cards include, for example, non-contact IC cards, magnetic cards, cards on which barcodes and 2D codes are printed, display devices on which barcodes and 2D codes are displayed, smartphones with membership card functions, and so on. Mobile phones, etc. can be mentioned.
Further, in step ST2, the control unit 1 performs a process of displaying, for example, "Please put the container" on the display unit of the display operation unit 3.

In step ST3, the control unit 1 performs the outer door opening process. Specifically, the control unit 1 releases the door lock portion of the outer door 111, and the outer door drive unit 5 performs drive control to move the outer door 111 to the open state.

In step ST4, the mass, material, presence / absence of contents, etc. of the object placed on the mounting unit 116 are detected by various detection processes by the measuring unit 7, the metal sensor 8, the optical sensor 9, etc., and the control unit 1 receives the detection process. Outputs a signal indicating the detected result.

In step ST5, the control unit 1 determines whether or not the outer door closing condition is satisfied. Specifically, when it is determined that the object placed on the mounting unit 116 is the object to be collected, the process proceeds to step ST6, and in other cases (in the case of a non-collected object such as a foreign substance), step ST51 Proceed to the process of.
As a result of the detection process, the control unit 1 determines, for example, that the article placed on the mounting unit 116 is an empty container, for example, a predetermined amount of liquid left over in the container. When it is detected that it is present, it may be determined that it contains a foreign substance.

In step ST6, the control unit 1 closes the outer door. Specifically, the control unit 1 drives and controls the outer door driving unit 5 so that the outer door is closed.

In step ST7, the control unit 1 determines whether or not a change in the measurement value by the measurement unit 7 is detected, and if the change in the measurement value is detected, proceeds to the process of step ST8, and in other cases, measurement. The detection process in step ST7 is continued until the change in the value subsides.

In step ST8, the control unit 1 determines whether or not the inner door opening condition is satisfied, and as a result of the determination, if the inner door opening condition is not satisfied, the process proceeds to step ST13, and if the inner door opening condition is satisfied, The process proceeds to step ST9. The condition for opening the inner door is, for example, that the object placed on the mounting portion 116 is the object to be collected.

In step ST9, the control unit 1 performs the inner door opening process. Specifically, the control unit 1 performs drive control by the inner door drive unit 6 so that the inner door 112 is in the open state.
In step ST9, the control unit 1 performs a process of displaying, for example, "recycling container XX" on the display unit of the display operation unit 3. As will be described later, in the case of the continuous loading process of containers, the control unit 1 counts up the number of containers and performs a process of displaying the number on the display unit. If it is not continuously charged, the control unit performs a process of displaying on one container and the display unit.

In step ST10, the control unit 1 closes the inner door. Specifically, the control unit 1 performs drive control by the inner door drive unit 6 so that the inner door 112 is closed. The inner door 112 is in a closed state, and the mounting portion and the volume reducing portion are separated (separated). Then, the process proceeds to step ST11.

In step ST11, the control unit 1 performs the outer door opening process. Specifically, the control unit 1 performs drive control by the outer door driving unit 5 so that the outer door 111 is opened. The outer door 111 is in the open state, and the next container can be put in.
In step ST11, the control unit 1 performs a process of displaying, for example, "Please put 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 or the like) touches the screen of the display operation unit 3, the end is declared.

In step ST12, the control unit 1 performs volume reduction processing. Specifically, the control unit 1 performs a process of reducing the volume of the empty container A by the volume reducing unit 120. The volume reduction process in step ST12 does not have to be performed. Further, the volume of the container may be reduced or not reduced as needed.

In step ST13, the control unit 1 determines whether or not a new article has been loaded into the mounting unit by a signal from each sensor, and as a result of the determination, the article is determined by any sensor (detection unit) of the mounting unit. When is detected, the process proceeds to step ST4, and when the article is not detected, the process proceeds to step ST14.
By proceeding to step ST4 as described above, the container can be continuously charged. Specifically, since the volume reduction unit is in a state where a new container can be put into the mounting unit while the empty container is being reduced in volume, it is detected by the sensor (detection unit) of the mounting unit. The processing and the volume reduction processing by the volume reduction unit can be performed in parallel. That is, the article collection device can efficiently reduce the volume of empty containers.
Further, even when the volume reduction process is not performed, the inner door 112 is closed during the volume reduction process, and the mounting portion and the volume reduction portion 120 are separated (separated state). Therefore, even if debris such as a container is scattered by the volume reduction process by the volume reduction portion, the debris does not reach the mounting portion.

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

In step ST15, the control unit 1 determines whether or not the volume reduction process of the container by the volume reduction unit 120 is completed, and if it is completed, proceeds to the process of step ST1, and if not, the process of step ST13. Proceed to. Specifically, in step ST15, the control unit 1 starts timing from the state where the outer door of ST11 is open, determines that there is no next container when a predetermined time has elapsed, and automatically performs the above-mentioned standby state. The process proceeds to step ST1.

In step ST51, the control unit 1 determines whether or not the outer door closing condition is satisfied in step ST5, and if it is determined that the object placed on the mounting unit 116 is a non-collected object, it is predetermined. It is determined whether or not the time, for example, about 30 seconds to 1 minute has elapsed, and as a result of the determination, if the predetermined time has elapsed, the process proceeds to step ST52, and if the predetermined time has not elapsed, the process proceeds to step ST52. It is in a standby state until a predetermined time elapses.

In steps ST52 and ST53, the control unit 1 performs an outer door closing process for closing the outer door 111 while maintaining the closed state of the inner door 112. Specifically, the outer door driving unit 5 is driven and controlled so that the control unit 1 and the outer door 111 are closed.

In step ST54, the control unit 1 performs the notification process. Specifically, in the control unit 1, when the non-collected object is placed on the mounting unit 116 of the container loading unit 110 and the outer door 111 is closed, the volume of the non-collected object is reduced. A process of notifying that the non-collected object remains in the input section of the section and that the non-collected object is removed from the mounting section 116 is performed. As the notification process, a process of displaying on the display unit of the display operation unit 3, a process of producing a predetermined notification sound, and a process of causing a light emitting element such as an LED to emit light are performed. Then, the process proceeds to step ST1.
Further, as the notification process of the control unit 1, the above notification may be performed to an external terminal device (not shown). The external terminal device is, for example, a POS terminal installed in a store, a portable terminal device carried by a store clerk or a system administrator, a host server, or the like. The control unit 1 may perform the above notification (pop-up screen display, lamp lighting, sound output, etc.) to the external terminal device by the transmission / reception unit 4 via a wireless or wired communication path. Further, the control unit 1 may output an error so that each terminal device can directly notify the error, or the control unit 1 may output an error to a higher-level server and the POS terminal or the like may perform the above notification via the server. Further, the control unit 1 may similarly notify other error information (fullness detection, replacement sign of consumable parts, other failure error, etc.).
In addition, after the processing of step ST54, the case where the collector of the container is specified and the case where the collector of the container is not specified will be described in detail.
When identifying the collector, the clerk or the like who received the notification sends and receives an IC card (the identification information for the administrator is stored in the storage unit of the IC card) or the like with the identification information for the administrator. When it is held over or touched (or brought close to) the unit 4, the control unit controls to open the outer door 111 after confirming that the authentication process has been performed correctly for the administrator. The outer door 111 is opened so that a clerk or the like can remove the uncollected material. That is, by giving the authority to open the outer door at the time of an error only to a limited number of people, it is possible to prevent further introduction of foreign matter and mischief.
When the collector is not specified, even if the outer door 111 is closed in ST52 and ST53 and foreign matter cannot be inserted, when the identification information is read from the IC card or the like by the transmission / reception unit 4, the control unit 1 will perform. Regardless of whether or not the administrator is an administrator, the process of opening the outer door 111 may be performed. As a result, the user who wants to use the article collection device can remove the non-collected object. That is, it is possible to prevent a chance loss that the article collection device cannot be used until a clerk or the like comes and removes the non-collected object.
