Description

Technical Field

[0001] This utility model relates to the field of printing equipment, and more specifically to an image forming device. Background Technology

[0002] In modern office environments, printers are indispensable office equipment, handling a large volume of document output. However, in actual use, users often encounter a frustrating problem: printouts are not properly categorized and processed. Specifically, when one user completes a printing task but fails to remove the printed paper promptly, and another user immediately initiates a new printing task, the papers from both jobs often become mixed together, making it difficult for subsequent users to distinguish which papers belong to which printing task.

[0003] To address this issue, various printers on the market have emerged that attempt to process print results in segments. Among them, such as... Figure 1 As shown, a common method of separating print jobs is to change the paper output direction to distinguish different printed documents. This method is often called "offset printing," and it uses the different paper orientations to allow users to visually identify different print jobs. However, while this method is simple, when dealing with a large number of print jobs, users still need to spend some time and effort to sort and organize them one by one.

[0004] Another more advanced method of component splitting involves using staples, primarily for large printers. For example... Figure 2 As shown, this method uses a stapler to secure sheets of paper from the same print job together with staples P after printing, thus creating a single document. This method is particularly suitable for large offices or print shops that handle a large volume of print jobs, as it greatly improves the neatness and legibility of the printed results. However, for general users, staplers not only increase costs but are also relatively cumbersome to use.

[0005] Therefore, a technical solution to the above problems is needed. Utility Model Content

[0006] To meet the functional requirement of paper sorting after printing, an image forming device was designed.

[0007] According to one aspect of the present invention, an image forming apparatus is provided, comprising a paper feeding device for sorting paper and a printing module for forming an image on the paper, including: A labeling assembly is installed in the image forming apparatus, having a label thereon, and the labeling assembly is drivable to move between a labeling position and a clearance position within the image forming apparatus; When the labeling component moves to the labeling position, the labeling component affixes the label to the paper printed by the printing module; When the labeling component moves to the clearance position, the labeling component avoids the paper printed by the printing module.

[0008] In some embodiments, the image forming apparatus further includes a printing tray for discharging and storing the paper that has been image-formed, and the labeling component is disposed within the printing tray.

[0009] In some embodiments, the printing paper tray is provided with a paper holder, and the labeling position is the position where paper is stored on the paper holder.

[0010] In some embodiments, a paper discharge roller is also included for discharging the paper printed by the printing module. In the paper output direction of the printing module, the paper discharge roller is located downstream of the paper output port of the printing module and upstream of the labeling position.

[0011] In some embodiments, a detection device for sensing paper is also included, the detection device being disposed within the printout tray, located between the paper feed roller and the labeling assembly.

[0012] In some embodiments, the label has an adhesive segment and a non-adhesive segment attached to the adhesive segment, and the labeling assembly moves to the labeling position, whereby the adhesive segment abuts against and adheres to the paper printed by the printing module. In some embodiments, there are multiple adhesive segments that are interconnected, and a break line is provided at the connection point so that the multiple adhesive segments can be separated under force.

[0013] In some embodiments, when the labeling component moves to the labeling position, at least a portion of the adhesive segment can be adhered to the paper printed by the printing module, so that this portion of the adhesive segment is separated from the other portions of the adhesive segment by the break line.

[0014] In some implementations, the number of non-paste segments is the same as the number of paste segments, and each paste segment is connected to one non-paste segment; When the adhesive segment is pasted onto the paper printed by the printing module, the non-adhesive segment is pasted onto the paper printed by the printing module together with the adhesive segment.

[0015] In some embodiments, the labeling assembly further includes a labeling roller that can be driven to move between a labeling position and a clearance position within the image forming apparatus, the label being detachably mounted on the labeling roller.

[0016] Compared with the prior art, the paper feeding device and image forming equipment of this utility model have the following advantages: The paper feeding device is equipped with a labeling component, which is installed inside the image forming equipment and can be driven to move. By driving the labeling component, a label is affixed to the specific page. The adhesive strip of the label can serve as a reminder to the user, allowing the user to quickly identify the separation status and realize the differentiation of print jobs by job number, copy number, etc. as needed.

[0017] Moreover, the paper feeding device only has labeling components, paper feeding rollers and detection devices. It has few parts and a simple structure, which can achieve the separation of printing jobs without significantly increasing the size and cost of the image forming equipment.

[0025] This utility model provides a paper feeding device in an embodiment for labeling and classifying paper. The paper feeding device in this embodiment will be described in detail below.

[0026] See Figures 3 to 7 A paper discharge device is used in an image forming apparatus 100 to assist in the discharge of paper 200 and to classify the paper 200 when the image forming apparatus 100 is printing.

[0027] See Figure 3 The image forming apparatus 100 (such as a copier, printer, fax machine, etc.) includes a main body. The main body includes a document reading section 110 at the top, a printing module 120 located below the document reading section 110 as an image forming section, and a paper feeding unit section 130 located further below. The document reading section 110 has a scanning module that can be used to scan documents. The printing module 120 is used to form a recording medium with an image. The paper feeding unit section 130 is provided with a paper tray, which is located inside the paper feeding unit section 130 of the main body and can be removed from the paper feeding unit to feed paper to the printing module 120 of the image forming section. The printing module 120 is also provided with a printing paper tray 140 at the paper output port, which is used to discharge and store the documents printed by the printing module 120. When the printer performs a printing job (image formation), the printing module 120 can take paper from the paper tray. After printing is completed, the paper 200 is discharged to the printing paper tray 140 and stacked and sorted on the paper discharge device, waiting for the user to take the paper 200. In this application, the paper discharge device is designed on the printing paper tray 140 to classify the documents discharged by the printing module 120.

[0028] This application improves the structural components of the paper feeding device. The specific structure and operation of the document reading part 110, the printing module 120 and the paper feeding unit part 130 in the image forming apparatus 100 are existing technologies and will not be described in detail here. Of course, the image forming apparatus 100 may not be limited to the above structure.

[0029] The following section will focus on the structure and working principle of the paper discharge device, but this is not intended to be limiting.

[0030] For better explanation, in this manual, the height direction of the image forming device 100 is defined as the Z-axis direction, which is also the plumb line direction. Upward is the +Z-axis direction, and downward is the -Z-axis direction. The paper tray loading direction is the X-axis direction, and the paper tray loading direction is the -X-axis direction. The direction perpendicular to the X-axis and Z-axis directions is the Y-axis direction. The Y-axis direction is also the opening direction of the printing paper tray 140. Inward is the +Y-axis direction, and outward is the -Y-axis direction. The Y-axis direction is also roughly the same as the paper discharge direction of the paper 200.

[0031] See Figures 4 to 7 The paper discharge device includes a paper discharge roller 150, a labeling assembly 160, and a detection device 170. The paper discharge roller 150 drives the paper 200 to move and discharge it to the print paper discharge tray 140. The labeling assembly 160 and the detection device 170 are both disposed within the print paper discharge tray 140. The detection device 170 detects a specific page printed by the printing module 120, and the labeling assembly 160 affixes a label 162 to that specific page. In use, when a specific page is detected, the labeling assembly 160 is activated to affix a label 162 to that specific page.

[0032] The paper discharge roller 150 is located at the paper outlet of the printing module 120, that is, in the paper output direction of the printing module 120. The paper discharge roller 150 is located downstream (-Y axis) of the paper outlet of the printing module 120. The paper discharge roller 150 can be driven to roll. After the paper 200 is discharged, the paper 200 passes through the paper discharge roller 150 and abuts against the paper discharge roller 150. When the paper discharge roller 150 is driven to rotate, the paper 200 is discharged by the friction between it and the paper discharge roller 150.

[0033] Preferably, when the paper 200 comes into contact with the paper discharge roller 150, the paper discharge roller 150 and the paper 200 are tangent.

[0034] Preferably, two paper discharge rollers 150 are provided, and the two paper discharge rollers 150 do not contact each other. After the paper 200 printed by the printing module 120 is discharged, it enters between the two paper discharge rollers 150 and abuts against the two paper discharge rollers 150 respectively. The two paper discharge rollers 150 rotate in opposite directions, so that the paper 200 can be discharged between the two paper discharge rollers 150.

[0035] The detection device 170 is a sensing structure used to sense the position of the paper 200. For example, the detection device 170 is a laser head or a copper micro switch used to detect the paper 200.

[0036] Preferably, the detection device 170 is located on the downstream side of the paper discharge roller 150 in the paper discharge direction, for sensing the paper 200 discharged by the paper discharge roller 150, that is, in the Y-axis direction, the detection device 170 is located on the -Y-axis side of the paper discharge roller 150.

[0037] The detection device 170 is positioned above and facing the paper 200 discharged from the paper discharge roller 150, and is used to sense the paper 200. Preferably, in the Z-axis direction, the detection device 170 is located on the +Z-axis side of the paper discharge roller 150.

[0038] Alternatively, in some other embodiments, the detection device 170 may also be located on the -Z axis side of the paper discharge roller 150, as long as the detection device 170 can detect the paper 200 discharged by the paper discharge roller 150, and there is no limitation here.

[0039] The labeling assembly 160 includes a labeling roller 161 and a label 162 mounted on the labeling roller 161. The labeling roller 161 can be driven to abut against the paper 200, so that the label 162 on the labeling roller 161 can be detached from the labeling roller 161 for affixing to the paper 200.

[0040] Preferably, the label 162 is provided with an adhesive segment 1622 and an adhesive segment 1621 connected to the adhesive segment 1622. Multiple adhesive segments 1622 are provided. When the labeling component 160 comes into contact with the paper 200, the adhesive segment 1622 can be pasted on the paper 200 to mark the paper 200.

[0041] Specifically, label 162 is label tape, which has an adhesive-backed adhesive section 1622, a non-adhesive section 1621, and a recyclable tape 1623. The labeling assembly 160 also includes a peeling component (not shown) and a recycling roller 163. The adhesive section 1622 is adhered to the recyclable tape 1625 and rolled onto the labeling roller 161. When the labeling roller 161 rotates, the adhesive section 1622 and the recyclable tape 1625 are separated by the peeling component. The recyclable tape 1625 is rolled onto the recycling roller 163 and recycled. Label 162 comes into contact with paper 200, and the adhesive-backed adhesive section 1622 can be adhered to the paper 200 to mark the paper 200. The non-adhesive section 1621 can be used for identification on the outside of the paper 200.

[0042] Preferably, the multiple adhesive segments 1622 are interconnected, and a break line 1623 is provided at the connection point. When the adhesive segment 1622 is pasted on the paper 200, the multiple adhesive segments 1622 can be disconnected from each other through the break line 1623, so that one adhesive segment 1622 can be pasted on one piece of paper 200, and the multiple adhesive segments 1622 on the label 162 can be pasted on multiple pieces of paper 200.

[0043] Preferably, the label 162 is further provided with a roll 1624, on which the recycled tape 1625 and the adhesive segments 1622 are all wound. The roll 1624 is provided with a central locking hole 16241. The roll 1624 is detachably mounted on the labeling roller 161 through the central locking hole 16241, so that the label 162 can be removed and replaced on the labeling roller 161 after the adhesive segments 1622 on the label 162 are used up. The adhesive segments 1622 and recycled tape 1625 wound on the roll 1624 can be tightened or loosened on the roll 1624 by rotating the roll 1624. In use, by rotating the roll 1624, the multiple adhesive segments 1622 wound on the roll 1624 can be respectively bonded to different products.

[0044] Preferably, the labeling roller 161 can be driven to rotate, so that multiple adhesive segments 1622 of the label 162 on the labeling roller 161 can sequentially abut against different sheets of paper 200, and can be pasted onto multiple sheets of different paper 200. For example, a rotary drive motor for driving the label 162 to rotate is provided on the labeling roller 161, so that the roll 1624 mounted on the labeling roller 161 does not need to rotate, and the adhesive segments 1622 on the roll 1624 can be sequentially discharged for pasting onto different sheets of paper 200.

[0045] The labeling assembly 160 can also move within the image forming apparatus 100 in a first position (labeling position) and a second position (avoidance position). When the labeling assembly 160 moves to the first position, the label tape of the labeling assembly 160 can come into contact with the paper 200 discharged by the paper discharge roller 150 and stick the label tape on the paper 200 that has already been image-formed. When the labeling assembly 160 moves to the second position, it is driven to the avoidance position, and the labeling assembly 160 moves away from the paper 200 discharged by the paper discharge roller 150, so that the paper 200 can pass through smoothly without being labeled 162.

[0046] Specifically, a drive device (not shown) and a track 180 are provided inside the printing paper tray 140. The track 180 is set along the Z-axis direction. The labeling roller 161 is mounted on the track 180 and can move movably. The labeling roller 161 is connected to the drive end of the drive device. The drive device can drive the labeling roller 161 to move up and down on the track 180, so that the labeling roller 161 can be driven to move up and down along the Z-axis direction, so that the label 162 on the labeling roller 161 can approach or move away from the paper 200 stored in the printing paper tray 140, for labeling or avoiding air gaps on the paper 200.

[0047] Alternatively, in some other embodiments, the printing paper tray 140 may not have a track 180, and the labeling roller 161 may be directly connected to the drive end of the drive device. The printing paper tray 140 has an elongated hole through which the labeling roller 161 can extend onto the printing paper tray 140. When the drive device is activated, the labeling roller 161 can move to the first position (labeling position) and affix the label 162 to the specific paper 200.

[0048] Preferably, the driving device can be a drive motor installed within the printing module 120. Alternatively, in some other embodiments, the driving device can also be a drive cylinder installed on the printing module 120.

[0049] The printout tray 140 has a paper holder 141 for storing paper 200. The paper holder 141 is used to store the paper 200 after the image is formed by the print module 120. Specifically, the paper holder 141 is a generally rectangular shell structure with an open top and a hollow interior, which can be used to store the paper 200. The paper holder 141 is located downstream of the paper outlet of the print module 120, and the paper 200 printed by the print module 120 can be temporarily stored on the paper holder 141.

[0050] Preferably, the first position (labeling position) is located inside the paper tray 141, and the second position (avoidance position) is located above the paper tray 141. Specifically, the track 180 extends within the printing module 120 until it reaches the paper tray 141 of the printing paper discharge tray 140. The labeling roller 161 can be driven to move on the track 180, allowing the labeling roller 161 to at least partially extend into the paper tray 141 and abut against the paper 200 stored in the paper tray 141 (first position), affixing the label 162 to the paper 200, thus completing the classification of multiple sets of paper 200. After labeling is completed, the labeling roller 161 can be driven to move on the track 180, moving away from the paper tray 141 along the Z-axis, to the second position (avoidance position) above the paper tray 141, no longer affecting the continued discharge of subsequent paper 200 onto the paper tray 141.

[0051] Alternatively, in some other embodiments, the paper tray 141 may not be provided. The first position (labeling position) may be located in a position where the paper 200 is stored in the printing paper tray 140 or on the path of the paper 200. The second position (avoidance position) may be a position that does not affect the discharge of the paper 200.

[0052] It also includes a controller (not shown), which is electrically connected to the detection device 170 and the labeling component 160. The detection device 170 feeds back the detected information of the paper 200 to the controller, which then controls the labeling component 160 to label the paper 200.

[0053] Preferably, the controller can be a PLC controller or a microcontroller.

[0054] Preferably, the controller is electrically connected to the detection device 170 and the drive device. The detection device 170 feeds back the detected paper 200 information to the controller, and the controller then controls the drive device to drive the labeling roller 161 to move and label the paper 200.

[0055] The following section will focus on the structure and working principle of the paper discharge device, but this is not intended to be limiting.

[0056] like Figure 4 and Figure 5As shown, the document reading section 110, printing module 120, and paper feeding unit 130 of the image forming apparatus 100 cooperate to perform printing. After printing, the paper 200 is discharged from the printing module 120 to the paper output roller 150. The paper output roller 150 normally drives the paper 200 to move to the printing paper output tray 140. When the paper head of the paper 200 passes the detection device 170, it is detected by the detection device 170. At this time, the labeling roller 161 is in the second position within the image forming apparatus 100.

[0057] When the detection device 170 detects that a specific page has arrived, the labeling roller 161 is driven to move downward along the Z-axis on the track 180. At this time, the label tape is pressed down with the labeling roller 161. The labeling roller 161 is in the first position, and the adhesive segment 1622 in the label tape abuts and adheres to the paper 200.

[0058] During this process, the adhesive backing of the label tape's adhesive section 1622 is of a fixed length, and the paper output speed of the paper feed roller 150 is constant. Therefore, the counter set inside the image forming equipment 100 can determine how long the label tape should be pressed down with the labeling roller 161 and how long the labeling roller 161 should be reset and lifted when the paper head of the paper 200 contacts the detection device 170, so that the adhesive section 1622 of the label tape contacts and adheres to the paper 200.

[0059] After the labeling is completed, the labeling roller 161 is driven by the drive device to move upward and reset on the track 180. During this process, the label tape is lifted with the labeling roller 161. Since the adhesive section 1622 of the tape is still attached to the paper 200, the label tape moves upward as a whole, generating tension. This causes the adhesive section 1622 of the label tape to break along the break line 1623 and separate from the label tape recycling tape 1625. At this time, the adhesive section 1622 is still attached to the paper 200 and is discharged with the paper 200.

[0060] Understandably, this can also be combined with the printing situation of the image forming device 100, such as when printing a single copy, by recognizing the current page number, the labeling action can be triggered when the paper 200 of a specific page (such as the first or last page of the printing job) moves to the detection device 170.

[0061] When printing multiple copies consecutively, the labeling action can be triggered when the paper 200 of a specific page (e.g., the first or last page of the print job) moves to the detection device 170, thus achieving separation by copy.

[0062] The paper feeding device and image forming equipment 100 of this application are equipped with a labeling component 160. The labeling component 160 is driven to attach a label 162 to a specific page. The adhesive tape of the label can serve as a reminder to the user, allowing the user to quickly identify the separation status. This enables the printing jobs to be separated according to the number of jobs or copies as needed. At the same time, it has fewer parts and a simpler structure, and can achieve the separation of printing jobs without significantly increasing the size and cost of the image forming equipment 100.

[0063] The above description is merely a preferred embodiment of the present utility model. To simplify the description, not all possible combinations of the various technical features in the above embodiments are described, and it is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall fall within the scope of the technical solution of the present utility model.
