The print position information is set, and as shown in FIG. 6, the start of printing indicates the distance (mm) from the tip of the band sheet s, and the origin O (0) is set at one end of the band sheet s in the width direction as the print position. , 0), and the width direction (X) and the longitudinal direction (Y) from the origin are set as starting points, and the width direction (printing area X width) and the longitudinal direction (printing area Y width) are set from the starting point. , This sets each print area. When the JAN code (bar code) is printed by sticking the label paper on the band sheet s, the sticking portion is driven so that the print position data of the JAN code matches the position where the label paper is stuck.
As described above, by associating the print format number with the product file, it is possible to print at a predetermined position on the band sheet according to the banded product by simply selecting each banded product and product number.
Further, instead of associating the print format number with each banded product, each tray number may be associated with each other. As shown in FIG. 5B, since the print format number is stored as an identifier in each tray number, the product information such as the product name of the selected product can be obtained by simply specifying the banded product (product number). Since the tray data (tray number) and print position information (print format number) are specified, the banded product can be banded and wrapped with the band sheet printed at the correct position according to the size of the tray. ..
If the print format number is associated with each product number of the product file and each tray number of the tray file, and the tray number is associated with each product number of the product file, for example, it is associated with the tray number. The printed format number may be used with priority, or vice versa, the print format number associated with each product number may be prioritized.

In detail, FIG. 8A is a diagram showing an example of a state in which the band sheet s (film) printed by the printing unit at the first time is being conveyed. In FIG. 8B, with the feed rollers 5a and 5b of the feed section 5 stopped, printing is performed while the band sheet s is conveyed by the platen roller 24 (printing roller) of the printing section, and the printed band sheet s is waited for. It is a figure which shows the state which is temporarily housed (standby) in part 80.
FIG. 8C is a diagram showing a state in which the printed band sheets s are temporarily accommodated (standby) in the accommodating portion 80c of the standby portion 80 with the feed rollers 5a and 5b stopped. In FIG. 8D, with the platen roller 24 (printing roller) of the printing unit stopped, the printed band sheet s (film) temporarily waiting in the standby unit 80 is wound by the feed rollers 5a and 5b. It is a figure for demonstrating an example of the operation of carrying to a side.

Next, an example of the banding operation using the loop guide (winding portion 101) in the first packaging mode of the banding packaging device 100 will be described.
The product (article) is carried in, and the product is placed on the mounting portion of the winding portion 101 (loop forming means). The detection unit outputs a signal to the control unit 57 that detects that the product has been placed on the winding unit.

The control unit 57 rotates and drives the platen roller 24 of the printing unit 4 and performs printing processing by the thermal head 4a (printing head) of the printing unit 4.

The control unit 57 performs a process of driving the feed roller of the feed unit so as to transport the band sheet s in the transport direction (positive direction). The band sheet s is conveyed to the winding portion 101.

The control unit 57 performs a process of gripping a predetermined portion of the band sheet s (film) by the first pressing plate 43 as the gripping portion.

The control unit 57 performs a process of driving the feed rollers 5a and 5b of the feed unit 5 in the opposite direction. Specifically, the feed unit 5 conveys the initial loop, which is a band sheet, in the pullback direction in which the diameter is reduced along the outer circumference of the banded product W.

The control unit 57 performs a process of stopping the feed rollers 5a and 5b of the feed unit 5.

The control unit 57 performs a process of gripping the overlapping portion of the strip sheet s (film) by the second pressing plate 44 as the grip portion, and the strip sheet s wound around the banded product W by the winding portion 101. A process of cutting a predetermined position (cutting position) of the (film) by the cutting portion 7 (cutter) is performed.

The control unit 57 performs a process of welding the polymerized portion of the band sheet wound around the banded product W by the heat welding unit 45 of the welding unit 6.
The band sheet s may be cut by the cutting portion 7 after the overlapping portion of the band sheet s by the heat welding portion 45 of the welding portion 6 is heat-welded, or conversely, the band sheet s may be cut by the cutting portion 7. After cutting, the polymerized portion of the band sheet s may be heat-welded by the heat-welding portion 45, or the above-mentioned cutting and heat welding may be performed substantially at the same time.

The control unit 57 drives and controls the first pressing plate 43, the second pressing plate 44, the heat welding portion 45, the cutting portion 7, etc. so as to move to the standby position, and the band sheet is wound from the winding portion 101. The product is carried out from a carry-out device (not shown).

As shown in FIGS. 8 (b) and 8 (c), the control unit 57 performs the feed rollers 5a and 5b of the feed unit 5 in parallel with the heat welding process and the product unloading process by the heat welding unit 45 described above. With the transport of the band sheet stopped by, the band sheet on which the product information is printed by the printing unit 4 is conveyed to the standby unit 80 by the rotational drive of the platen roller 24 of the printing unit 4, and the band sheet is transferred to the standby unit 80. Performs the process of waiting.
Specifically, by driving the platen roller 24 of the printing unit 4 while the feeding of the band sheet by the feed unit 5 is stopped, the band sheet s (film) is bent, and the curved portion where the band sheet is bent is downward. Is temporarily accommodated in the accommodating portion 80c through the opening 80a of the standby portion 80.
A regulation unit 88 is arranged between the platen roller 24 of the printing unit 4 and the feed rollers 5a and 5b of the feed unit 5, and the regulation unit 88 has a curved portion which is a bent portion of the band sheet. Regulate moving upwards. Normally, a band sheet s (film) is arranged between the regulating portion 88 and the opening 80a of the standby portion 80.

The control unit 57 determines whether or not to end the process of winding the band sheet, and in detail, a series of cases when it is detected that the end button of the key operation unit 10 or the display operation unit 9 is operated. In other cases, the product is carried in and the product is placed on the mounting portion of the winding portion. The detection unit outputs a signal to the control unit 57 that detects that the product has been placed on the winding unit.
Then, as shown in FIG. 8D, the control unit 57 performs a process of driving the feed roller of the feed unit 5 so as to transport the band sheet in the transport direction (forward direction). The band sheet housed in the standby unit 80 is conveyed to the winding unit 101. The banding packaging device 100 repeats the banding packaging operation as appropriate.

FIG. 9 is a conceptual diagram showing an example of the band wrapping device 100 according to the embodiment of the present invention.
As shown in FIG. 9, in the banding wrapping device 100, when the band sheet s is fed, the set shaft (roll support shaft) rotates forward so as not to affect the feeding of the band sheet s, and the band sheet is swung. Then, the band sheet s is sent out.
Specifically, as described above, the loading unit 2 has a rotation support shaft 21 attached to the center at the place where the band sheet roll R (film roll) is loaded, and the rotation support shaft 21 is the motor 15 (band). It is configured to be driven by a sheet winding drive motor). When the band sheet is unwound from the band sheet roll R, the motor 15 is driven and controlled so that the rotation support shaft 21 rotates in the forward direction (counterclockwise in the example shown in FIG. 9).
Further, when the band sheet roll R is rotated in the reverse direction by the motor 15, the pullback portion of the band sheet s due to the reverse rotation of the feed portion 5 is wound around the band sheet roll R. Further, the loading unit 2 is configured to prevent the band sheet s from sagging by controlling the tension roller g1 and the take-up drive motor 15.
Specifically, the tension roller g1 is provided at the end of the arm portion gu1 pivotally supported by a rotation shaft (not shown) provided coaxially with the rotation support shaft 21. The arm gu1 is provided with a tension detection unit (tension sensor) for detecting the tension of the band sheet s, and a drive motor (non-existent) that moves the position of the tension roller g1 in an arc shape according to the tension of the band sheet s. (Shown) is provided.
That is, the control unit of the band wrapping device 100 has a movable roller (driven roller) for control. The movement of the movable roller (driven roller) is controlled so that the tension (tension) of the band sheet is kept constant when the band sheet is sent out and when it is wound up.
That is, even if the feed amount (rotation angle of the set shaft (roll support shaft)) required for transporting the strip sheet differs depending on the outer diameter of the strip sheet roll R, the tension (tension) of the strip sheet s (media) is different. ) Can be maintained at the specified value (constant value).

Next, an example of the operation when the feeding of the band sheet s from the band sheet roll R is stopped will be described.
When the load is no longer applied to the tension roller g1 (movable roller) (when the load changes from a large state to a small state), the tension roller g1 (movable roller) returns to the specified position (upper position). The positions of the arm gu1 and the tension roller g1 are controlled by the drive motor. In this case, the drive motor 15 of the band seat set shaft (roll support shaft) may be configured to rotate only by the reaction force without operating.

<Large tray mode (second packaging mode)>
FIG. 10 is a front view of the winding portion 101 (loop forming portion) of the banding packaging device 100 in an open state (second packaging mode (in the large tray mode)). FIG. 11 is a perspective view of the band wrapping device 100 shown in FIG. FIG. 12 is a conceptual diagram for explaining the operation of the banding device in the second packaging mode. The notification lamp 71 provided on the upper part of the main body 100a of the banding packaging device 100 notifies a failure, a packaging abnormality, a packaging mode, or the like.

There are various sizes of products to be packaged, and when a product that does not fit in the window hole 11 of the winding portion 101 is packaged, the winding portion 101 cannot be used as it is for band-wrapping.
In the band-wrapping device 100 according to the embodiment of the present invention, the band-wrapping sheet is manually placed on the product W (article) with respect to the large-sized product W (article) that cannot be placed in the window hole 11 of the winding portion 101. ) Can be wound.
For example, in the banding packaging device 100 shown in FIGS. 10 to 12, the winding portion 101 as a loop forming means can rotate around the rotation shaft 100g with respect to the main body portion 100a of the banding packaging device 100. It is provided.

For example, when the product W (article) exceeding the maximum size that can be wound in the window hole 11 of the winding portion 101 is manually wrapped in a band, the rotating shaft 100 g is rotated as shown in FIGS. 10 to 12. By rotating the winding portion 101 as the center to open the winding portion 101, it is possible to easily switch between the normal size and the large size.
The operator grasps the band sheet s delivered by a predetermined amount from the feed section 5 (belt sheet transport section) with a finger or the like, forms a small loop, holds it by the receiving plate 46, the welding section 6, or the like, and then wraps the band. The packaging device 100 expands the loop to a size slightly larger than the size of the object to be packaged. That is, a predetermined amount is further paid out so as to have a length of the band sheet s that can be banded and wrapped according to the object to be packaged.
Next, when the object to be packaged is arranged in the loop of the band sheet s by the operator, the band sheet s is narrowed down by the band wrapping device 100 to wind the band sheet s around the object to be packaged. The polymerized portion is heat-welded by the heat-welded portion of the welded portion 6.

The control unit 57 may change the control of the normal band winding operation to the operation for a large size by rotating the winding unit 101 to open it. Further, as shown in FIG. 11, when the attachments AT1 and AT2 for a large size are attached to the main body 100a, the control unit 57 detects the attachments AT1 and AT2 by a detection unit (not shown) and performs a normal band winding operation. You may want to change the control of to the behavior for larger sizes. It should be noted that the attachment / detachment of the attachments AT1 and AT2 is not indispensable for switching between the normal band winding operation and the operation for a large size.

FIG. 13 is a perspective view showing a stored state of the receiving plate 46 of the banding packaging device 100 according to the embodiment of the present invention. FIG. 14 is a perspective view showing a protruding state of the receiving plate 46 of the band hanging packaging device 100.

As shown in FIGS. 13 and 14, the receiving plate 46 is formed in a groove formed in the main body 100a when the loop guide (winding portion 101) is opened from the main body 100a of the banding packaging device 100. On the other hand, it is formed so as to be in a protruding state or a non-protruding state.
Specifically, in the second mode (large tray mode), the receiving plate 46 is in a protruding state as shown in FIG. After the packaging is completed, the receiving plate 46 is in a non-protruding state as shown in FIG.

The tip guide member 401 shown in FIGS. 13 and 14 corresponds to the attachment AT1 shown in FIG.
As shown in FIG. 14, the gap between the tip guide member 401 (AT1) for guiding the tip of the band sheet s and the receiving plate 46 serves as an insertion port for the band sheet s.
Specifically, as shown in FIGS. 13 and 14, the tip guide member 401 has an inclined surface portion 401d at the end of the main body of the tip guide member 401 and a flat portion having a thickness thinner than that of the main body of the tip guide member 401. 401f and the like are provided.
Further, in the tip guide member 401, a pair of width direction regulating members 401t and 401t are erected on the inclined surface portion 401d and the flat portion 401f. The distance between the pair of width direction regulating members 401t and 401t is defined to be substantially the same as the width of the band sheet.

FIG. 15 is a diagram for explaining an example of the operation of the band wrapping device 100. In detail, FIG. 15A is a diagram for explaining the band sheet, and FIG. 15B is an example of a state in which the packaging material (band sheet) is sent out from the packaging material roll by a set amount (set length). FIG. 15 (c) is a diagram for explaining the formation of a small loop.

As shown in FIGS. 15 (a) and 15 (b), the strip sheet s is fed out from the packaging material roll by a predetermined amount through the through hole 43h of the first pressing plate 43 (front clamp). Specifically, the band sheets s are fed out by the feed rollers 5a and 5b (feed rollers) of the feed unit 5 (see FIGS. 8 and 9).

Next, as shown in FIG. 15C, the operator grips the band sheet s with a finger F or the like, and the tip s1 of the band sheet s is inserted into the insertion port between the tip guide member 401 and the receiving plate 46. Insert the band sheet s.

As shown in FIG. 16A, the operator inserts, for example, the tip s1 of the band sheet s into the lower part of the receiving plate 46.
Next, the control unit of the band-hanging packaging device moves the first pressing plate 43 upward and presses the band sheet s against the receiving plate 46 to fix the band sheet s, thereby fixing the band sheet s. Form a small loop of.

Next, as shown in FIG. 16B, the control unit of the band-wrapping device expands the diameter of the loop-shaped band sheet so as to be slightly larger than the outer peripheral dimension of the object to be packaged. Specifically, the feed rollers 5a and 5b (feed rollers) of the feed unit 5 feed out the strip sheet s by a length corresponding to the size of the object to be packaged (see FIGS. 8 and 9).
Then, the object to be packaged is placed in the loop of the band sheet s by an operator or the like.

Next, as shown in FIG. 17, the control unit of the banding packaging device winds the band sheet s around the object to be packaged (commodity W) by narrowing down the band sheet s. Specifically, the band sheets s are reverse-fed by the feed rollers 5a and 5b (feed rollers) of the feed unit 5.

Next, as shown in FIG. 18, the control unit of the band hanging packaging device raises the second pressing plate 44 and sandwiches the packaging member (band sheet s) between the receiving plate 46 and the second pressing plate 44. Then, the polymerized portion of the band sheet s is welded (fixed) by the heat-welded portion 45, and the strip sheet s is cut by the cutter of the cutting portion 7, and then the receiving plate 46 is placed in a non-protruding state. Perform the processing.
As described above, in the large tray mode (second packaging mode), even the object to be packaged that fits in the loop guide (winding portion 101) can be wrapped in a band.
As a result, the tip of the film is inserted into the device so that the operator moves the film along the article to form a loop having a diameter larger than that of the article, as in the wrapping machine of Patent Document 2. It is not necessary to perform a complicated operation of inserting the film at the (insertion position), and it is also improved that the length of the film to be sent differs depending on the size of the article and it is difficult to handle.

Although the second mode is the large tray mode, even in the case of a particularly small banded product (tray), the feeding of the band sheets s can be minimized by packaging in the second mode. .. Therefore, the tray that can be wrapped in the first mode can be packaged in the second mode.

FIG. 19 is a diagram showing an example of a setting screen (printing start position setting method is manual) of the band wrapping device. FIG. 20 is a diagram showing an example of a setting screen (printing start position setting method is automatic) of the band wrapping device.

As shown in FIGS. 19 and 20, for example, the setting screen that is operably displayed on the display operation unit of the wrapping device is the tray name setting unit D91 for setting the name of the tray as the object to be packaged.

Next, for example, setting of a tray as an object to be packaged will be described.
Printing start position setting method As the printing start position setting method of the printing start position setting unit D92, either manual or fixed can be selected, and the printing start position is set. When manual is selected, the print start position is automatically set according to the left edge of the tray based on the tray size. When fixed is selected, "print start position adjustment (mm)" is set as the print start position.

The tray width upper surface (mm) of the tray width upper surface setting unit D93 is the width of the tray upper surface, and a value within a predetermined range such as 50 to 270 can be set. The tray width upper surface (mm) can be set when the printing start position setting method is other than "fixed".

The tray width lower surface (mm) of the tray width lower surface setting unit D94 is the width of the tray lower surface, and a value within a predetermined range such as 50 to 270 can be set. The lower surface of the tray width (mm) can be set when the printing start position setting method is other than "fixed".

The height (mm) of the height setting unit D95 is the height of the tray, and a value within a predetermined range such as 10 to 150 can be set. This height (mm) can be set when the printing start position setting method is other than "fixed".

The print start position adjustment (mm) of the print start position adjustment unit D96 is a print start position adjustment, and a value within a predetermined range such as -50 to +50 can be set.
When "manual" is selected as the print start position setting method, the print start position adjustment value (mm) can be set from the left end position of the tray that is automatically adjusted.
The print start position adjustment (mm) can be set when the print start position setting method is other than "fixed".

The print start position (mm) of the print start position setting unit D97 is the print start position, and the initial value is 0 mm, and a value within a predetermined range such as 0 to 200 can be set. The print start position (mm) can be set when the print start position setting method is other than "fixed".

The narrowing down amount adjustment (mm) is an adjustment of the narrowing down amount, and the initial value is 0, and a value within a predetermined range such as −99 to +99 can be set.

The packaging start method of the packaging start method setting unit D98 can be set to automatic or manual.
The automatic packaging start method means that when the packaged object detection unit (product detection sensor) or the like detects that a tray or the like as an object to be packaged is placed on the packaging unit on the loop guide, it is wrapped. This is the operation mode for starting packaging.
When the packaging start method is manual, the touch panel type issue button that is operably displayed on the screen with the packaging start pop-up displayed on the display operation unit (without displaying it if there is no display operation unit) , This is an operation mode in which wrapping is started when the issue button of hardware such as a foot switch is operated.

Is adjustable. Further, the narrowing down amount (mm) of the narrowing down amount adjustment setting unit D99 can be finely adjusted according to the strength of the banded product W.

FIG. 21 is a diagram showing an example of a functional block of the control means (control unit 57) of the banding packaging device 100 according to the embodiment of the present invention.

The control unit (control unit 57) includes acquisition means 570, packaging type determination means 571 (determination means), packaging control means 572, notification means 573, and the like. Each function of the control unit (control unit 57) can be realized in the wrapping device as a computer by executing a control program stored in the storage unit, for example.

FIG. 22 is a diagram showing an example of a functional block of the control means of the banding packaging device 100 according to the embodiment of the present invention.

The acquisition means 570 acquires the size of the packaged object. The acquisition means 570 may acquire the dimensions (size) of the packaged object from the storage unit, for example, or based on a signal from an optical sensor (not shown) that acquires the dimensions (size) of the packaged object. , The size of the packaged object may be obtained.

The packaging type determining means 571 determines a packaging type (first packaging mode 572A, second packaging mode 572B, etc.) corresponding to the packaging conditions of the object to be packaged (tray or the like) input by the input means.
Further, the packaging type determining means 571 (determining means) determines whether or not the packaged object is packaged by the packaging operation in the closed state of the winding portion 101 based on the information acquired by the acquiring means 570.

When the guide state detection unit 542 detects the open state or the removed state of the loop guide (winding unit 101), the packaging control means 572 does not use the loop guide (winding unit 101) to cover the object to be packaged. (Product W including trays, etc.) is processed, and in other cases (the loop guide (winding portion 101) is attached to the main body or closed), the loop guide (winding portion 101) is used. A process of wrapping the object to be packaged (commodity W including a tray or the like) placed inside using a loop guide (winding portion 101) is performed.
That is, the packaging control means 572 has a first packaging mode 572A, a second packaging mode 572B, and the like.

The notification means 573 includes a packaging format (first packaging mode 572A, etc.) corresponding to the packaging conditions of the input means (display operation unit 9, key operation unit 10, etc.) and the object to be packaged (tray, etc.) input by the input means. When the packaged object is designated by the packaging type determining means 571 for determining (second packaging mode 572B, etc.) and the input means (display operation unit 9, key operation unit 10, etc.), the specified packaged object is specified. Based on the packaging type corresponding to the packaging conditions and the state of the loop guide (winding unit 101) detected by the guide state detection unit (guide state detection unit 542), the packaged object is packaged according to the determined packaging type. It is determined whether or not packaging is possible, and if the result of the determination is that packaging is not possible, a process for notifying that fact is performed.
Further, the notification means 573 notifies the determination means 571 so that the winding portion 101 is opened when it is determined that the packaging operation in the closed state is impossible.
In the case of the second packaging mode, the banded packaging can be performed regardless of the size of the packaged object. Therefore, even if the packaged object is suitable for the first packaging mode, the banded packaging can be performed. If the number of items to be packaged is small, it may be more efficient to continue the operation in the second packaging mode. Therefore, in such a case, the operation in the first packaging mode may be prompted and the control for continuing the packaging mode may be performed.
Furthermore, when the indicated quantity for wrapping is input in advance and the quantity is regulated by the countdown (that is, when the production amount is determined so as not to wrap too much), it depends on the input quantity. Therefore, the continuation of the packaging mode may be prohibited and the operation in the first packaging mode may be forcibly controlled, that is, the operation in the second packaging mode may be prohibited.

FIG. 22 is a flowchart for explaining an example of the operation of the banding packaging device 100 according to the embodiment of the present invention.

In step ST1, the guide state detection unit 542 detects the open / closed state (guide state) of the loop guide (winding unit 101) with respect to the main body 100a, and outputs the detection result to the control unit 57.

In step ST2, the control unit 57 determines whether or not the loop guide (winding unit 101) is in the open state or the removed state with respect to the main body unit 100a, and as a result of the determination, the loop guide is in the open state or removed. If it is determined that the state is in the above state, the process proceeds to step ST11, and in other cases, the process proceeds to step ST3.

In step ST3, the control unit 57 shifts to the packaging process in the normal mode (first packaging mode).

In step ST4, the control unit 57 performs a process of designating the packaged object, for example, based on a signal from an input device or the like of the display operation unit 9. Specifically, for example, from the list of objects to be packaged set in the storage unit, the object to be packaged is selected as the object to be packaged.

In step ST5, the control unit 57 determines whether or not the packaging conditions corresponding to the object to be packaged cannot be packaged in the current packaging format (packaging mode defined from the state of the loop guide). If packaging is not possible, the process proceeds to step ST8, and in other cases, the process proceeds to step ST6.
Specifically, the control unit 57 determines whether or not the packaging conditions and the packaging format corresponding to the designated object to be packaged are appropriate.

In step ST6, the control unit 57 performs a process of setting packaging conditions corresponding to the object to be packaged.

In step ST7, the control unit 57 performs the packaging process in the normal mode (first packaging mode), and ends the process after the packaging process. If necessary, such as when the packaging process is continuously performed, the process proceeds to step ST1.

In step ST8, the control unit 57 performs a notification process for notifying that the packaging process is impossible, and proceeds to the process of step ST1.

In step ST11, the control unit 57 shifts to the large tray mode (second packaging mode).

In step ST12, the control unit 57 performs a process of designating the packaged object, for example, based on a signal from an input device or the like of the display operation unit 9. Specifically, for example, the packaged object is selected as the object to be packaged from the list of the packaged objects preset in the storage unit.

In step ST13, the control unit 57 performs a process of setting packaging conditions corresponding to the object to be packaged.

In step ST14, the control unit 57 performs the packaging process in the large tray mode (second packaging mode), and ends the process after the packaging process. If necessary, such as when the packaging process is continuously performed, the process proceeds to step ST1.

When the loop guide is opened or removed from the main body 100a of the banding wrapping device 100, the banding wrapping device cannot perform banding packaging using the loop guide. ..
When the loop guide is closed or the loop guide is attached to the main body, the band-wrapping device 100 can perform normal band-wrapping packaging by using the loop guide.

Next, an example of the operation of the banding packaging device in the large tray mode (second packaging mode) will be described with reference to FIG. 23 and the like.
