In step ST23, the control unit 31 performs a manual pasting process. Specifically, the operator (operator) manually attaches a long waiting mountless label to the article. Then, when the detection unit detects that the top-paste-less label has been removed from the label standby unit and the article to which the mount-less label has been attached has been removed, the control unit 31 cancels the manual attachment mode. Then, the process shifts to the automatic label affixing mode, and the process proceeds to step ST31.

In step ST31, the control unit 31 performs a process of generating a label image of the underlaying mount-less label based on the product information and the like. The label length (length in the label transport direction) of the mountless label for underlaying is specified according to the amount of printing of print items, and is calculated by creating a label image for underlaying.

In step ST32, the control unit 31 performs a process of issuing a mountless label for underlaying by the undercoat label issuing unit.

In step ST33, the control unit 31 determines whether or not the length (label length) of the underlaying mount-less label in the label transport direction is equal to or greater than the second set value, and if it is equal to or greater than the second set value, in step ST37. The process proceeds, and in other cases, the process proceeds to step ST34.

In step ST34, the control unit 31 causes the undercoat label to stand by at a normal standby position. In the present embodiment, in this normal standby position, the upper end (tip portion) of the backing sheet-less label placed on the underlaying label transporting portion is slightly smaller than the transporting surface of the underlaying article transporting portion. It is specified in a low position.

In step ST35, the control unit 31 transports the article in the article transport direction by the article transport unit for underlaying.

In step ST36, the control unit 31 uses the mount-less label for under-pasting so that the upper end (tip portion) of the under-pasting mount-less label is higher than the transport surface of the under-pasting article transport section. By transporting the article by the label transport section and by transporting the article in the article transport direction by the article transport section for underlaying, the underlaying mountless label is attached to the bottom of the article. Then, the control unit 31 proceeds to the process of step ST11 in order to perform the packaging process and the label affixing process for the next article.

In step ST37, the control unit 31 shifts to the hand-pasting mode and drives and controls the under-pasting label transport unit so as to stand by at a position where the upper end of the under-paste label protrudes upward from the article transport surface. ..

In step ST38, the control unit 31 performs drive control to stop the article transport unit for underlaying.

In step ST39, the control unit 31 performs notification processing. Specifically, the notification processing unit 313 of the control unit 31 determines by the determination unit (determination unit 311) that the label length of the label issued by the undercoat label issuing unit as the issuing means exceeds the second set length. If so, a process to notify that fact is performed. The notification process includes, for example, a process of displaying the effect on the display unit 39, a process of notifying the effect by a sounding unit (not shown) of a speaker, a voice processing circuit, or the like, and a process of emitting a light emitting unit indicating the effect. Can be mentioned. The notification processing unit 313 of the control unit 31 may perform notification processing for prompting the article to manually attach a mount-less label.

In step ST40, the control unit 31 performs a manual pasting process. Specifically, the operator (operator) manually attaches a long waiting mountless label for underlaying to the article. Then, when the detection unit detects that the underlaying mount-less label has been removed from the label waiting unit and the article to which the backing-less label has been attached has been removed, the control unit 31 cancels the hand-pasting mode. Then, the process shifts to the automatic label affixing mode, and the process proceeds to step ST11.

In the above-described embodiment, when a relatively long label is attached in steps ST18, ST21, ST22, ST23, ST33, ST37, ST38, ST40, etc., the transportation of the article is stopped to notify the effect. Although the processing was performed and the manual pasting processing was performed, the present invention is not limited to this embodiment. When the control unit can determine that the label is relatively long when the information (product information, etc.) related to the product (article) to be packaged is called from the storage unit 32, etc. by operating 38 or the like and setting is performed. It is also possible to notify the hand-paste processing mode so that it can be selected and select the hand-paste mode.
Whether or not the label length exceeds a certain length can be determined when the product information is called (it can be known while the product is loaded), so when the product information is called, "This product has a long underlaid label. Therefore, the control unit 31 can make the display unit 39 of the display operation unit h notify the notification such as "No automatic attachment is performed." Or "Because the under-paste label is long, please apply it by hand."
As an example of the notification, for example, on the display unit 39 of the display operation unit h, "This product has a long undercoat label, so automatic attachment is not performed.", "This product has a long underlay label, so it is manually attached.""Pleasedo","This product has a long top-paste label, so automatic sticking is not performed", "This product has a long top-paste label, so please stick it by hand", etc. Appropriate notification (pop-up display, etc.) is given according to the length of the underlay label.

In the above-described embodiment, the packaging device attaches the top-pasting mount-less label and the bottom-pasting mount-less label to the article packaged by the packaging unit, but the present invention is not limited to this embodiment. For example, the packaging device may attach either the top-pasting mount-less label or the bottom-pasting mount-less label to the article. Further, the sticking device may be an embodiment in which a mount-less label for top sticking or a mount-less label for bottom sticking is attached to an article that is packaged or not packaged. When issuing a mount-less label longer than the set length, the packaging device or the sticking device may stop the transport of the article by the transport means and shift to the manual sticking mode.

In addition, the control unit of the packaging device reports when the issued label remains at the label affixing position, etc. without being affixed to a predetermined article, or when the label remains at the label affixing position, etc. due to an error or the like. The label is detected by a detection sensor (not shown), and the control unit confirms that "the label remains. All labels (top label issuing unit 40 (Q), bottom label issuing unit 40U)". , Please remove the label. ”And so on to the display unit 39 of the display operation unit h.

In addition, if the control unit of the packaging device can identify the part from which the label has been removed in each detection unit, for example, even if a notification process such as "the label of the undercoat part remains" is performed. good. The notification process is preferably displayed until the label is removed. If it detects that the label has been removed, the notification is automatically cleared. After the notification is erased, the normal state is reached, and when the product is loaded into the loading section (product loading section), the loading conveyor (carrying / transporting section) starts transporting the product to the packaging section.

<Control to stop even if either the top label or the bottom label is long>
Further, in the above-described embodiment, the control unit of the packaging device controls to stop the conveyor transport according to the length of the undercoat label, but the control unit is not limited to the underlay label. Control may be performed to stop the conveyor transfer when the length of the label exceeds a certain length. Specifically, if the length of the label exceeds a certain amount, the label affixing device (robot arm, manipulator, etc.) that sucks the label and carries it to the article cannot carry the label well. The unit performs stop control by the sorting and transporting unit k in order to encourage manual pasting. Further, the control unit is displayed on the display unit 39 of the display operation unit h so that the reason why the label is stopped is the top label or the bottom label, so that the operator can perform a hand based on the notification of the display unit. You can easily check the label to be attached.
