The present disclosure relates to an image forming apparatus, configured to form an image on a rolled print medium, and a method.
There is known a label finisher system such as a post-processing machine that can perform, for example, a series of processing from shape cutout to winding in one-pass. The label finisher system requires restrictions related to specifications such as maximum processable roll diameter, maximum weight, maximum length, or the like, of a roll sheet. For example, in a case of winding finish of a label roll sheet, restrictions related to an outer size of a delivery roll sheet is required such that the roll sheet fits the size that can be accommodated in a machine such as a labeling machine that performs automatic labeling.
In a label roll printing factory, on the other hand, there arises a task of separating the roll sheet product into a plurality of rolls before delivery, in accordance with a request provided from a user at the delivery site about the outer size and the number of rolls for delivery of the delivery roll sheet (quantity of delivery rolls).
For example, when a roll sheet product having an image formed thereon is delivered with no change, there is the risk that, as illustrated in
Japanese Patent Laid-Open No. 2018-202754 describes about reducing the generation of useless regions in cutting continuous paper by performing a printing process with an optimal job interval required for post-processing.
There is a need for improving the convenience of the task of separating a roll sheet product into a plurality of rolls.
The present disclosure provides an image forming apparatus and a method that improve the convenience of the task of separating a product of a rolled print medium into a plurality of rolls.
The present disclosure in one aspect provides an image forming apparatus comprising: a setting unit configured to set a partition region for dividing a rolled print medium into a plurality of rolls, the partition region being set within a group of images that are sequentially printed accompanying feeding from a feeding apparatus in which a rolled print medium is set; and a printing unit configured to print, on the print medium fed from the feeding apparatus, the group of images reflecting the partition region set by the setting unit, wherein the printing unit prints, on the partition region, an identification image indicating a cutting position for dividing into the plurality of rolls, and the setting unit sets a position at which the identification image is printed, based on information of the group of images.
According to the present disclosure, it is possible to improve the convenience of the task of separating a product of rolled print medium into a plurality of rolls.
Further features of the present disclosure will become apparent from the following description of exemplary embodiments with reference to the attached drawings.
Hereinafter, embodiments will be described in detail with reference to the attached drawings. Note, the following embodiments are not intended to limit the scope of the claimed invention. Multiple features are described in the embodiments, but limitation is not made an invention that requires all such features, and multiple such features may be combined as appropriate.
Furthermore, in the attached drawings, the same reference numerals are given to the same or similar configurations, and redundant description thereof is omitted.
The feeding apparatus 10 is an apparatus configured to supply the roll sheet P to the image forming apparatus 20. The feeding apparatus 10 rotates a paper tube of the roll sheet P around a rotating shaft 11 as a center to convey the roll sheet P wound around the paper tube toward the image forming apparatus 20 at a constant speed through a plurality of rollers (e.g., a conveyance roller and a paper feed roller).
The image forming apparatus 20 performs a control to form an image on the roll sheet P supplied from the feeding apparatus 10. The image forming apparatus 20 conveys the roll sheet P having an image formed thereon toward the winding apparatus 30. In the present embodiment, the image forming apparatus 20 is a labeling apparatus configured to print, for example, a plurality of groups of labels (groups of images) continuously in the feed direction.
The winding apparatus 30 is an apparatus configured to wind the roll sheet P conveyed from the image forming apparatus 20 around a paper tube as a center into a roll shape. In the winding apparatus 30, the roll sheet P is wound around a paper tube of a rotating shaft 31 and held in a roll shape, as illustrated in
The print medium for label printing (label roll sheet) includes a label part and a releasing part, for example. A generation method of the label product includes a method that prints on a label roll sheet and subsequently collects sheets of a releasing part at post-processing to generate the label product, and a method that preliminarily collects sheets of a releasing part from a yet-to-be printed roll sheet and prints on the remaining label region to generate the label product. In particular, a yet-to-be printed label in a state where sheets of a releasing part is preliminarily collected from the yet-to-be printed roll sheet is referred to as a blank label or a die-cut label. For example,
Next, a control configuration of the image forming system 1 will be described in detail.
The sheet conveyance unit 21 is a conveyance mechanism for the roll sheet P inside the image forming apparatus 20 that conveys, by a plurality of rollers, for example, the roll sheet P that has been conveyed from the feeding apparatus 10 to the image forming unit 22, and conveys the roll sheet P that has passed through the image forming unit 22 to the winding apparatus 30.
The image forming unit 22 forms an image on the roll sheet P supplied from the feeding apparatus 10, based on print data to which an output instruction is received. The roll sheet P having an image formed thereon by the image forming unit 22 is conveyed toward the winding apparatus 30. The communication unit 23 includes a communication control card such as a Local Area Network (LAN) card, for example. The communication unit 23 is configured to transmit and receive various types of data to and from an external apparatus (e.g., an information processing apparatus such as a PC) connected to a communication network such as a LAN, a Wide Area Network (WAN), or the like. Here, the communication network may be any of a wired network, a wireless network, or a network of a mixture of them.
The control unit 24 includes, for example, a Central Processing Unit (CPU), a Random Access Memory (RAM), or the like, and collectively controls the image forming system 1. The CPU of the control unit 24 reads out various programs such as system programs and processing programs stored in the storage unit 25, deploys them to the RAM, and executes various processes according to the deployed programs. For example, the control unit 24 can perform an image forming process that executes an image forming job (simply referred to as a job below) in accordance with the user's instruction. The storage unit 25 includes, for example, a non-volatile semiconductor memory (e.g., flash memory) or a Hard Disk Drive (HDD). The storage unit 25 has stored therein various programs such as system programs and processing programs to be executed by the control unit 24, and various types of data required to execute the programs.
The operation display unit 26, which is formed of a liquid crystal display (LCD) with a touch panel, for example, includes a display unit 26a and an operation unit 26b. The display unit 26a displays various types of information on a display screen in accordance with a display control signal input from the control unit 24. The operation unit 26b, including various types of operation keys such as a numeric keypad and a start key, accepts various input operations performed by the user, and outputs operation signals to the control unit 24. The operation display unit 26 is used for setting partition information in performing a job, for example.
Here, the partition information is information indicating an insertion position at which a partition information page is preliminarily inserted into the job, in a case where the roll sheet product P′ subjected to the image forming process is needed to deliver in a manner separated into a plurality of rolls. In other words, preliminarily inserting the partition information into the job allows for reflecting the partition information page in the printed product. The insertion position information of the partition information page includes, for example, information of the number of pages in a roll, roll length information, partition length, and roll number information. In the present embodiment, the partition information is generated by using the number of pages to be printed, the number of labels to be printed, the printing length, or the like as a partition condition.
The label detection unit 27, which is an apparatus configured to detect a label region to be printed on a roll sheet, includes a light projecting unit such as a photoelectric sensor or a laser sensor, for example. The label detection unit 27 detects a label by detecting, for example, an edge between each label and the paper liner. In addition, the label detection unit 27 may be configured to detect a preliminarily printed mark for identifying a position.
Next, there will be described an operation of the image forming apparatus 20 when the image forming process is performed on the roll sheet P.
First, the user generates data for a job in an external apparatus such as a PC, and performs print setting of the job and setting of the number of rolls for delivery. Here, “number of rolls” in the present embodiment represents the number of delivery rolls. The data for a job and a job ticket including the information of the print setting of the job and setting of the number of rolls for delivery are transmitted to the image forming apparatus 20 via the communication network. The control unit 24 of the image forming apparatus 20 accepts the data for a job and the job ticket transmitted from the external apparatus via the communication unit 23.
The job information includes, for example, a document name, number of pages, number of copies, type of paper, and number of rolls for delivery. In addition, the job information includes page size, layout information of blank labels (blank label transverse width, spacing between blank labels, or the like), although not illustrated in
A display item 302 is a button that can accept an instruction to delete, from the storage unit 25, information of a job stored in the storage unit 25 which corresponds to the job selected in the display item 301. The display item 303 is a button that can accept an instruction to set partition information for the job selected in the display item 301. Pressing the display item 303 causes a setting screen of partition information to be displayed. The display item 304 is a button that can accept an instruction to start image formation of the job selected in the display item 301.
A display item 403 is a control for setting the length of a partition information page (referred to as partition length below). Setting of the partition length from the user can be accepted, and the default value of the partition length is 0.0 m. In a case of the default value 0.0 m, a partition information page is not generated.
A display item 404 is a screen that displays an image when the partition information set by the user is added to the job. A display item 405 is a print preview screen that displays an image of the print result in which the partition information page set by the user is added to the job.
A display item 406 is used for changing the page displayed on the preview screen. A display item 407 is a button that can accept an instruction to store the partition information and the partition information page, which are set by the user, in the storage unit 25. By pressing the display item 407, the partition information and the partition information page, which are set by the user, are stored in the storage unit 25. A display item 408 is a button for canceling the partition information and the partition information page which are set by the user. By pressing the display item 408, the partition information and the partition information page, which are set by the user, are cleared.
In the following, there will be described a process of generating a partition information page in accordance with the user's setting.
First, a case in
At S501, the control unit 24 acquires job data of the display item 401 and setting information of the display item 402 and the display item 403.
At S502, the control unit 24 determines whether or not the partition length L is greater than 0 m. When, for example, the partition length L is set to 0 m as illustrated in
At S509, the control unit 24 generates a preview of an image diagram in which the partition information page generated in accordance with the user's setting is added to the job. However, the partition length L is 0 m in the case of
Next, the case of
At S501, the control unit 24 acquires job data of the display item 401 and setting information of the display item 402 and the display item 403.
At S502, the control unit 24 determines whether or not the partition length L is greater than 0 m. When, for example, the partition length L is set to 1.0 m, as illustrated in
At S503, the control unit 24 acquires a remainder length R. As illustrated in
remainder length R=partition length L % (label transverse width W+label spacing D) (1)
When, for example, the partition length L is 1.0 m, the label transverse width W is 2.7 cm, and the label spacing D is 3 mm, the remainder length R as a remainder calculated by Equation (1) is 10 mm.
At S504, the control unit 24 calculates the number of partitioning blank labels N with respect to the partition length L. As illustrated in
number of partitioning blank labels N=partition length L/(label transverse width W+label spacing D) (2)
For instance, the number of partitioning blank labels N calculated by Equation (2) is 30 in the aforementioned example.
At S505, the control unit 24 generates an identification image such as a QR code (trade name) indicating the partition information set by the user. For example, partition information such as number of pages in a roll, length of roll, partition length, and roll number information are generated as a QR code. Although a QR code is described in the following as an example of the identification image, a one-dimensional bar code, a mark or the like may also be used instead of a two-dimensional bar code, provided that it indicates the partition information. In addition, a character string or numbers that allows the user to visually recognize the content may be used instead of a coded image such as a QR code.
At S506, the control unit 24 determines whether or not the remainder length R calculated at S503 is greater than the label spacing D. When, for example, the remainder length R calculated by Equation (1) is greater than the label spacing D as illustrated in
At S507, the control unit 24 increments, according to Equation (3), the number of partitioning blank labels N calculated by Equation (2).
number of partitioning blank labels N=number of partitioning blank labels N+1 (3)
For instance, the number of partitioning blank labels N calculated by Equation (3) in the aforementioned example is 31.
At S508, the control unit 24 generates a partition information page. The present embodiment generates a partition information page by generating N partitioning blank labels to be inserted at a leading end and an end point of each roll, and laying out the QR code generated at S505 at the N-th partitioning blank label to be inserted at the leading end and the end point. In other words, the QR code is laid out at a position corresponding to the arrangement of groups of labels in the partition information page.
For example, in the case of the aforementioned example, the partition information page is generated by inserting 31 partitioning blank labels at the leading end and the end point of a roll and laying out a QR code at the 31st partitioning blank label inserted at the leading end and the end point.
At S509, the control unit 24 generates a preview image indicating an image with the partition information page generated in accordance with the user's setting added to the job. For example, a preview image is displayed in the display item 404 together with partition information, as illustrated in
In the display item 405, a preview image is displayed which indicates an image with the job set to be one-roll and partition information pages of a case of 1.0 m being inserted at the leading end and the end point of the roll 1. In addition, the display item 410 indicates a QR code laid out at the 31st partitioning blank label inserted at the leading end of a roll 1. The display item 411 indicates a QR code laid out at the 31st partitioning blank label inserted at the end point of the roll 1. However, the number of partitioning blank labels is omitted in
Next, the case of
At S501, the control unit 24 acquires job data of the display item 401 and setting information of the display item 402 and the display item 403.
At S502, the control unit 24 determines whether or not the partition length L is greater than 0 m. When, for example, the partition length L is set to 0.9 m, as illustrated in
At S503, the control unit 24 acquires the remainder length R. As illustrated in
remainder length R=partition length L % (label transverse width W+label spacing D)
When, for example, the partition length L is 0.99 m, the label transverse width W is 3 cm, and the label spacing D is 3 mm, the remainder length R calculated by Equation (1) is 0 mm.
At S504, the control unit 24 calculates the number of partitioning blank labels N with respect to the partition length L. As illustrated in
number of partitioning blank labels N=partition length L/(label transverse width W+label spacing D)
For example, the number of partitioning blank labels N calculated by Equation (2) is 30 in the aforementioned example.
At S505, the control unit 24 generates a QR code indicating the partition information set by the user. For example, partition information such as number of pages in a roll, length of roll, partition length, and roll number information are generated as a QR code. Here, the partition information included in the QR code is not limited to the aforementioned information, provided that it allows determination of the amount of the roll sheet to be wound by a cutting machine 100 described below.
At S506, the control unit 24 determines whether or not the remainder length R calculated at S503 is greater than the label spacing D. When, for example, the remainder length R calculated by Equation (1) is smaller than the label spacing D as illustrated in
At S508, the control unit 24 generates a partition information page. The present embodiment generates a partition information page by generating N partitioning blank labels to be inserted at the leading end and the end point of each roll, and laying out the QR code generated at S505 at the N-th partitioning blank label to be inserted at the leading end and the end point.
For instance, in the case of the aforementioned example, the partition information page is generated by inserting 30 partitioning blank labels at the leading end and the end point of each roll and laying out a QR code at the 30th partitioning blank label inserted at the leading end and the end point of each roll.
At S509, the control unit 24 generates a preview image indicating an image with the partition information page generated in accordance with the user's setting added to the job. For example, a preview image is displayed in the display item 404 together with partition information, as illustrated in
In the display item 405, a preview image is displayed which indicates an image with the job set to be two-roll and partition information pages of a case of 0.99 m being inserted at the leading end and the end point of each roll. In addition, the display item 410 indicates a QR code laid out at the 30th partitioning blank label inserted at the leading end of the roll 1. In addition, the display item 412 indicates a QR code laid out at the 30th partitioning blank label inserted at the end point of the roll 1. In addition, the display item 413 indicates a QR code laid out at the 30th partitioning blank label inserted at the leading end of a roll 2. The display item 411 indicates a QR code laid out at the 30th partitioning blank label inserted at the end point of the roll 2. However, the number of partitioning blank labels is omitted in
A region 420 of
At S701, the control unit 24 acquires job data of the job selected by the display item 301.
At S702, the control unit 24 acquires the job ticket of the job selected by the display item 301, and the partition information and the partition information page generated by the users setting.
At S703, the control unit 24 determines the presence or absence of a partition information page. When it is determined that there is no partition information page, the process proceeds to S705. When, on the other hand, it is determined that there is a partition information page, the process proceeds to S704.
Based on the partition information set by the user, the control unit 24 divides, at S704, the job into a plurality of rolls based on the start page and the end page of each roll included in the partition information, and adds the partition information page before and after each roll.
At S705, the control unit 24 performs a Raster Image Processing (RIP) on the job to generate image data for printing. The job here has no partition information page added when it is determined at S703 that there is no partition information page, or has a partition information page added when it is determined at S703 that there is a partition information page. At S706, the control unit 24 causes the image forming unit 22 to form an image on the roll sheet P based on the image data, and subsequently terminates the process illustrated in
Next, there will be described an effect of the present embodiment in a case of performing printing by the image forming system 1 and temporarily winding the roll sheet P in the winding apparatus 30, and subsequently forming it into a delivery form. In such a case, the cutting machine 100 illustrated in
The cutting machine 100 is an apparatus configured to adjust the length of the roll sheet P temporarily wound in the image forming system 1 to the length of the delivery form. The cutting machine 100 includes a sheet feeding unit 100a configured to be set the roll sheet and feed the roll sheet, a winding unit 100b configured to wind the roll sheet being fed, and a cutter 100c configured to cut the roll sheet being fed at the end point of the roll into a form of a delivery product.
After setting the product P′ illustrated in
As such, in the image forming system, the operator can easily grasp the final delivery form, by adding partition information to a region that can be visually recognized in a state of wound in a roll shape. In addition, by reading the QR code at the leading end of the delivery product with a QR code reader, as illustrated in
In the following, a second embodiment will be described, focusing on the difference from the first embodiment.
In
Since the partition length L is set to 1.0 m as illustrated in
At S803, the control unit 24 calculates the remainder length R. As illustrated in
remainder length R=partition length L % (page transverse width W+page spacing D) (4)
When, for example, the partition length L is 1.0 m, the page transverse width W is 210 mm, and the page spacing D is 2 mm, the remainder length R calculated as a remainder by Equation (4) is approximately 152 mm.
At S804, the control unit 24 calculates the number of partitioning blank pages N for the partition length L. As illustrated in
number of partitioning blank pages N=partition length L/(page transverse width W+page spacing D) (5)
For instance, the number of partitioning blank pages N calculated by Equation (5) is 4 in the aforementioned example.
At S805, the control unit 24 generates a two-dimensional barcode such as a QR code indicating the partition information set by the user. For example, partition information such as number of pages in a roll, length of roll, partition length, and roll number information are generated as a QR code. Although a QR code is described in the following as an example, a one-dimensional bar code may also be used instead of a two-dimensional bar code, provided that it indicates the partition information.
At S806, the control unit 24 determines whether the remainder length R calculated at S803 is greater than the page spacing D. For example, when the remainder length R calculated by Equation (4) is greater than the page spacing D as illustrated in
At S807, the control unit 24 increments, according to Equation (6), the number of partitioning blank pages N calculated by Equation (5).
number of partitioning blank pages N=number of partitioning blank pages N+1 (6)
For instance, in the case of the aforementioned example, the number of partitioning blank pages N calculated by Equation (6) is 5.
When, on the other hand, the remainder length R calculated by Equation (4) at S806 is smaller than the page spacing D, the control unit 24 determines that the remainder length R is not greater than the page spacing D, and advances the process to S808.
At S808, the partition information page is generated. The present embodiment generates a partition information page by generating N partitioning blank pages to be inserted at the leading end and the end point of each roll, and laying out the QR code generated at S805 at the N-th partitioning blank page to be inserted at the leading end and the end point. In other words, the QR code is laid out at a position corresponding to the arrangement of the page group in the partition information page.
As such, the remainder length R is calculated in the present embodiment based on the page size and the page spacing of the job entered. This may be configured such that one job corresponds to one page illustrated in
According to the embodiments, as has been described above, a position at which a blank label can be printed is specified in a partition information page, and a QR code is printed thereon. Such a configuration allows for appropriately printing a QR code presenting a cutting position even on the print medium including a region such as a paper liner on which printing is impossible.
