Description

Technical Field

[0001] This invention relates to the field of printing equipment technology, and more specifically to a printer for roll-to-roll consumables. Background Technology

[0002] Printers using roll-to-roll consumables require frequent replacement of roll-to-roll consumables. To facilitate emergency replacement of consumables, some printers now feature a spare consumables compartment.

[0003] Specifically, the printer features a button panel and display screen on the front, and a consumables storage mechanism on the right side. This mechanism can rotate and pop out to the outside of the right side of the printer body. When the consumables storage mechanism pops out, the entrance to the main consumables compartment is opened, exposing the main consumables compartment to the right side of the printer body. The consumables storage mechanism mainly includes a back plate and a first positioning shaft protruding from the back plate, as well as a paper guide structure. When the consumables storage mechanism pops out, the user can install the roll of consumables onto the first positioning shaft of the popped-out consumables storage mechanism from front to back, facing the front of the printer, and rest the lead-out section of the roll of consumables against the paper guide structure. When the consumables storage mechanism is closed, a paper path and a paper outlet are formed between the consumables storage mechanism and the main body. The roll of consumables enters the main consumables compartment, and the lead-out section passes through the paper path and extends out of the printer body from the paper outlet. Of course, the printer also has a paper cutting mechanism corresponding to the paper path. The spare consumables compartment is located on the back of the printer and has a separate cover. The spare consumables compartment contains a second positioning shaft. The spare consumables compartment can store one spare consumable. When the main consumable is used up, remove the rear cover, take out the spare consumable, and replace the used consumable in the consumables storage mechanism.

[0004] While existing printers can be configured with spare consumables, replacing them is a complex process. Summary of the Invention

[0005] The purpose of this invention is to provide a printer that makes replacing spare consumables simpler.

[0006] The printer provided by the present invention includes a main body, which has a first consumable compartment and a second consumable compartment. The first consumable compartment has a first positioning shaft, and the second consumable compartment has a second positioning shaft. The main body has a paper feeding channel and a paper output port. The first consumable compartment, the paper feeding channel and the paper output port are connected in sequence. The first consumable compartment and the second consumable compartment open on the same side of the main body, and the second consumable compartment is connected to the paper feeding channel.

[0007] As can be seen from the above scheme, under this setup, when a roll of consumables in the first consumables compartment runs out and the spare consumables in the second consumables compartment need to be replaced, after removing the used first consumables, the spare consumables do not need to be disassembled. The lead-out section of the spare consumables is simply placed into the paper feed channel and passes through the paper output port, after which the spare consumables directly operate in the second consumables compartment. It is evident that since the openings of the first and second consumables compartments are on the same side of the main body, the replacement operation does not require flipping the machine, making the operation more intuitive. Furthermore, it eliminates the need for multiple openings of the covers or mechanisms to open and close the two consumables compartments separately, and reduces the need to remove and re-place the spare consumables. Therefore, it significantly reduces the amount of work involved in the consumables replacement process, making the replacement operation much simpler. Furthermore, if the first consumable cannot be disposed of after removal in the current situation, the tail section of the first consumable can be directly wound up (the tail section leaves the paper path and returns to the first consumable compartment), allowing the first consumable to be temporarily placed in the first consumable compartment. This does not affect the normal rotation and conveyor belt of the spare consumable. In addition, in emergency situations, the operation of removing the first consumable can be reduced, and the access and use of the spare consumable can be completed quickly, further improving the replacement efficiency.

[0008] A further proposed solution is to connect the second consumables compartment to the paper feeding channel via the first consumables compartment.

[0009] As can be seen from the above, even if the location of the paper feed channel is limited by the layout of modules such as the cutter mechanism and printhead assembly, and is closer to the first consumable compartment and farther away from the second consumable compartment, the spare consumables in the second consumable compartment can still pass through the first consumable compartment into the paper feed channel. Therefore, even if the location of the paper feed channel is limited and farther away from the spare consumables, it does not affect the spare consumables from directly feeding and working in their own consumable compartment, and there is no need to occupy additional space to add a new channel directly to the paper feed channel for the second consumable compartment.

[0010] A further proposed solution is that, on the axial projection of the first positioning axis, the area between the two tangents connecting the smallest circumcircle of the first positioning axis and the smallest circumcircle of the second positioning axis is defined as the first region; when the consumables in the second consumables compartment are in the conveyor belt state, the conveyor belt leading out from the second consumables compartment passes through the conveyor belt passage point, which is the last point on the conveyor belt path that has the minimum distance from the largest concentric circle that can accommodate the first consumables compartment, and the conveyor belt passage point is outside the first region.

[0011] As can be seen above, when the current consumable in the second consumable compartment is being used, and the user has replenished the spare consumable in the first consumable compartment, the current consumable in the second consumable compartment will bypass the unused, largest-diameter spare consumable because it enters the paper feed channel through the first consumable compartment. However, if the wrap angle of the current consumable on the spare consumable is too large, the friction experienced by the current consumable as it passes the spare consumable will be significant, affecting the smoothness of the paper feed. Setting the paper feed point outside the first area reduces this wrap angle, decreases the area of ​​the current consumable pressing on the spare consumable, reduces friction, and ensures smooth paper feed.

[0012] Another further solution is to have both the first and second consumables compartments directly connected to the paper feeding channel.

[0013] As can be seen from the above, if the location of the paper feeding channel is not restricted, it would be better to set the paper feeding channel between the first consumables compartment and the second consumables compartment. Consumables in both compartments can directly access the paper feeding channel, avoiding mutual interference between the two rolls of consumables and resulting in better conveyor performance.

[0014] A further proposed solution is to have a paper tape inlet in the paper feeding channel, with the paper tape inlet, the opening of the first consumables compartment, and the opening of the second consumables compartment located on the same side of the main body.

[0015] As can be seen from the above, compared to inserting the paper tape along the paper feeding path into the paper feeding channel, the paper tape insertion port allows the paper tape to be inserted into the paper feeding channel along the width direction of the paper tape (the axial direction of the first positioning axis), making the operation simpler; and the complete path of the paper feeding channel can be observed through the paper tape insertion port, which is beneficial for aligning the position when inserting the paper tape and reducing the difficulty of operation.

[0016] A further solution includes an openable cover, which, when opened, exposes the openings of the first consumables compartment, the second consumables compartment, and the paper tape insertion port.

[0017] As can be seen from the above, under this setting, only one opening and closing operation is required for each consumable replacement process.

[0018] A further embodiment is that the cover includes a cover plate; the cover includes a first pressing structure protruding from the cover plate toward the first consumable compartment, and / or, the cover includes a second pressing structure protruding from the cover plate toward the second consumable compartment.

[0019] As can be seen from the above, the pressing structure can stabilize the axial position of the consumables in the consumables compartment, suppress axial displacement, and improve print quality.

[0020] Another further option is to place the first and second consumables compartments at different locations along the length of the main body.

[0021] As can be seen from the above, the consumables compartment occupies a large area, so it is more reasonable to arrange two consumables compartments by utilizing the space in the direction of the largest size of the main body.

[0022] A further proposed solution is that, in the width direction of the main body, the paper outlet is located on the first side, and both the first and second consumable compartments are located on the second side in the width direction.

[0023] As can be seen from the above, this setting can fully free up space on the first side in the width direction to set up the print head assembly and paper cutting mechanism, and the layout of each module is more reasonable.

[0024] Another further solution is to place the first consumables compartment, the second consumables compartment, and the paper feeding channel on the same plane.

[0025] As can be seen from the above, this setting can fix the two rolls of consumables in the same axial position, ensuring that the consumables in both consumable compartments can accurately align with the paper feed path, thus guaranteeing printing quality. Attached Figure Description

[0038] First embodiment of the printer See Figure 1 The printer in this embodiment is a roll-to-roll consumable printer, specifically a thermal label printer. The printer includes a main body 1 and a cover 2, and of course, it also includes a printhead assembly, paper cutting mechanism, and circuit module, which are present in existing thermal printers but are not shown. The printhead assembly, paper cutting mechanism, and circuit module can be implemented using existing technology.

[0039] See Figure 1 In this embodiment, the cover 2 is a flip cover that covers the back of the main body 1. The cover 2 is hinged to the main body 1 and the hinge axis is parallel to the length direction of the main body 1 (the y-axis direction in the figure).

[0040] The main body 1 is provided with a first consumables compartment 11, a second consumables compartment 12, a paper feed channel 13, and a paper output port 14. Consumables installed in the first consumables compartment 11 or the second consumables compartment 12 are fed out from the paper output port 14 after passing through the paper feed channel 13. The printhead assembly and the paper cutting mechanism are set corresponding to the paper feed channel 13, and printing and paper cutting are performed sequentially when the paper tape passes through the paper feed channel 13.

[0041] First, the paper output slot 14 is located on one side of the main body 1 in the width direction (x-axis direction in the diagram). Then, as... Figure 1 As shown, the first consumable compartment 11, the second consumable compartment 12, and the paper feeding channel 13 are arranged on substantially the same plane. When the cover 2 is opened, the first consumable compartment 11, the second consumable compartment 12, and the paper feeding channel 13 are all exposed on the back side of the main body 1. More specifically, the first consumable compartment 11 and the second consumable compartment 12 are recessed into the back side of the main body 1 along the thickness direction (the z-axis direction in the figure) and both open along the thickness direction of the main body 1 to the back side of the main body 1. This opening is the inlet and outlet of the consumable compartment. Although the paper feeding channel 13 feeds paper along a plane perpendicular to the thickness direction of the main body 1 (xy-axis plane), in this embodiment, the paper feeding channel 13 is provided with a paper tape inlet 132. The paper tape inlet 132 is opened on the back side of the main body 1 along the thickness direction of the main body 1 and extends between the two ends of the extension of the paper feeding channel 13. The extension end of the paper feeding channel 13 is the paper outlet 14.

[0042] With this setup, when the cover 2 is opened, the openings of the first consumables compartment 11, the second consumables compartment 12, and the paper tape insertion port 132 of the paper feed channel 13 are exposed together. Users can not only install or remove roll consumables from the back of the main body 1, but also no longer need to perform the tedious operation of threading one end of the paper tape through the paper feed channel 13 when inserting the paper tape into the paper feed channel 13. Instead, the paper tape can be directly inserted into the paper tape insertion port 132 along the width direction of the paper tape (the z-axis direction shown in the figure, which is also the thickness direction of the printer). The operation is simpler, and the complete path of the paper feed channel 13 can be observed through the paper tape insertion port 132, which is conducive to aligning the position when inserting the paper tape and reducing the difficulty of operation.

[0043] See Figure 1 and Figure 2 The main body 1 includes a first bottom wall 112 of a first consumable compartment 11 and a first surrounding structure 113 surrounding the first consumable compartment 11. A first positioning shaft 111 protruding from the first bottom wall 112 is also provided inside the first consumable compartment 11. The main body 1 also includes a second bottom wall 122 of a second consumable compartment 12 and a second surrounding structure 123 surrounding the second consumable compartment 12. A second positioning shaft 121 protruding from the second bottom wall 122 is also provided inside the second consumable compartment 12. Both the first positioning shaft 111 and the second positioning shaft 121 extend along the thickness direction of the main body 1, i.e., they are parallel to each other. The first surrounding structure 113 mainly includes an arc surface concentric with the first positioning shaft 111, and the second surrounding structure 123 mainly includes an arc surface concentric with the second positioning shaft 121.

[0044] Among them, such as Figure 2 As shown, in this embodiment, the first bottom wall 112 and the second bottom wall 122 have a certain height difference in the thickness direction of the main body 1. The internal space of the main body 1 facing away from the first consumable compartment 11 and the second consumable compartment 12 needs to be equipped with circuit modules. Since different circuit components have a certain height difference, the first bottom wall 112 and the second bottom wall 122 are adapted and adjusted. Since the height difference between the first bottom wall 112 and the second bottom wall 122 is small and the paper tape is flexible, this setting does not affect the normal passage of the first consumable 91 in the first consumable compartment 11 and the second consumable 92 in the second consumable compartment 12 through the paper feeding channel 13.

[0045] See also Figure 1The cover 2 includes a cover plate 21, a first pressing structure 22 protruding from the cover plate 21 towards the first consumable compartment 11 in the closed state, and a second pressing structure 23 protruding from the cover plate 21 towards the second consumable compartment 12 in the closed state. Both the first pressing structure 22 and the second pressing structure 23 are hollow cylindrical structures. When the first consumable 91 is placed in the first consumable compartment 11, in the closed state of the cover 2, the first pressing structure 22 and the first bottom wall 112 limit the first consumable 91 from both axial sides. When the second consumable 92 is placed in the second consumable compartment 12, in the closed state of the cover 2, the second pressing structure 23 and the second bottom wall 122 limit the second consumable 92 from both axial sides. The protrusion heights of the first pressing structure 22 and the second pressing structure 23 are different, thus adapting to the height difference between the first bottom wall 112 and the second bottom wall 122.

[0046] Of course, in a better embodiment, the first bottom wall and the second bottom wall are coplanar, and the first consumable compartment, the second consumable compartment and the paper feed channel are on the same plane. This can fix the two rolls of consumables in the same axial position, ensuring that the consumables in the two consumable compartments can be accurately connected with the paper feed channel, thus ensuring the printing effect.

[0047] Combined Figure 3 In this embodiment, the first consumable compartment 11 and the second consumable compartment 12 are arranged at different positions along the length of the main body. Furthermore, the first consumable compartment 11 and the second consumable compartment 12 are arranged sequentially along the length of the main body 1. Specifically, on the axial projection of the first positioning shaft 111, the axis of the first positioning shaft 111 and the axis of the second positioning shaft 121 are arranged sequentially along the length of the main body 1.

[0048] In addition, the width direction of the main body 1 ( Figure 3 In the x-axis direction, the paper outlet 14 is located on the first side 108, and the first consumable compartment 11 and the second consumable compartment 12 are both offset towards the second side 109 in the width direction. The paper feed channel 13 connects the first consumable compartment 11 and the paper outlet 14. With this configuration, a second region S2 and a third region S3 can be formed on opposite sides of the paper feed channel 13 inside the main body 1. The printhead assembly is located in the second region S2, and the cutter mechanism is located in the third region S3. This configuration makes the structural layout of the main body 1 more reasonable.

[0049] Since the paper feed channel 13 is directly connected to the first consumables compartment 11 and the paper feed channel 13 is located relatively far from the second consumables compartment 12, in this embodiment, the second consumables compartment 12 needs to be connected to the paper feed channel 13 through the first consumables compartment 11.

[0050] In the printer of the present invention, both the first consumable compartment 11 and the second consumable compartment 12 are connected to the paper feed channel 13. Whether it is the first consumable 91 in the first consumable compartment 11 or the second consumable 92 in the second consumable compartment 12, the paper tape can be directly drawn out from the current consumable compartment and passed into the paper feed channel 13. The first consumable 91 can work directly in the first consumable compartment 11, and the second consumable 92 can work directly in the second consumable compartment 12.

[0051] Therefore, when the consumables in a consumables compartment are used up, you can choose to remove the used consumables or directly reel in the tail section of the first consumable (the tail section leaves the paper path and returns to the first consumables compartment), so that the used consumables are temporarily placed in their original consumables compartment. The spare consumables do not need to be disassembled. After the lead-out section of the spare consumables is placed into the paper path 13 and passes through the paper outlet 14, the spare consumables will work directly in their original consumables compartment.

[0052] Furthermore, the first consumable compartment 11 and the second consumable compartment 12 open on the same side of the main body 1, eliminating the need to flip the machine during replacement. This makes the process more intuitive and avoids the need to open and close the two consumable compartments twice. Therefore, compared to existing technologies, the present invention effectively simplifies the replacement of spare consumables, making it more intuitive and simpler, and improving emergency replacement efficiency.

[0053] See also Figure 1 and Figure 3 In one scenario, when the second consumable 92 in the second consumable compartment 12 is being used, and the user has already replenished the first consumable compartment 11 with a spare consumable (first consumable 91), the paper tape 921 of the second consumable 92 needs to pass through the first consumable compartment 11 to enter the paper path 13. In this case, the paper tape 921 of the currently working second consumable 92 will bypass the unused, largest-diameter spare consumable (first consumable 91). However, if the wrap angle of the paper tape 921 on the first consumable 91 is too large, the friction force experienced by the paper tape 921 when passing through the first consumable 91 will be large, affecting the smoothness of the tape feed.

[0054] Therefore, a better arrangement is to set the conveyor belt passing point 9a outside the first region S1.

[0055] Among them, on the axial projection of the first positioning axis 111, the area between the two tangents L (shown in red) connecting the smallest circumcircle 111a (shown in red) of the first positioning axis 111 and the smallest circumcircle 121a (shown in red) of the second positioning axis 121 is the first region S1.

[0056] Among them, see Figure 3When the second consumable 92 in the second consumable compartment 12 is in the conveyor state, that is, the second consumable 92 is fed out and printed, at this time, on the axial projection of the first positioning axis 11, the paper tape 921 (shown as a green curve) led out by the second consumable 92 (shown as a green circle) will pass through the conveyor pass point 9a. The conveyor pass point 9a is a point on the paper tape 921, which is the last point on the conveyor path of the paper tape 921 that has the minimum distance from the maximum accommodating concentric circle 11a (shown as a blue dashed line) of the first consumable compartment.

[0057] The largest concentric circle 11a that can be accommodated is the largest circle that can be placed into the first consumable compartment 11 and is concentric with the first positioning axis 11. In this embodiment, the conveyor pass point 9a is the last intersection point of the paper tape 921 and the largest concentric circle 11a on the conveyor path. The intersection point is the minimum distance, which is zero.

[0058] In fact, the point 9a that the conveyor passes through is a point on the paper tape 921. Its position is affected by the entrance position of the paper path 13. The further the entrance position of the paper path 13 is from the first area S1, the further the position of the point 9a that the conveyor passes through is from the first area S1. Since the point 9a that the conveyor passes through is the last point with the smallest distance on the conveyor path, the paper tape 921 will only move further away from the first consumable 91 after passing through the point 9a. Therefore, if the point 9a that the conveyor passes through is outside the first area S1, it can ensure that the wrap angle of the paper tape 921 on the first consumable 91 is small, reduce friction, and ensure the smoothness of the conveyor.

[0059] Second embodiment of the printer See Figure 4 In this embodiment, the first consumable compartment 31 and the second consumable compartment 32 are inclined to the length direction of the main body, but they are still in different positions in the length direction of the main body.

[0060] In this embodiment, the conveyor belt passes through point 33, which is also located outside the first region 34.

[0061] Third embodiment of the printer See Figure 5 Similar to the second embodiment, the first consumable compartment 35 and the second consumable compartment 36 are inclined to the length direction of the main body, but they are still in different positions in the length direction of the main body, and the conveyor belt passing point 38 is also located outside the first area.

[0062] Unlike the second embodiment, the paper path 37 and the paper outlet are located at different positions, and the path of the paper tape will also change. This makes the location of the paper tape passing point 38 in this embodiment different from the location of the paper tape passing point 33 in the second embodiment.

[0063] Fourth embodiment of the printer See Figure 6 In this embodiment, the tape passing point 43 is also located outside the first region 44, but a portion of the paper feeding channel 45 is located within the first region 44. Under this configuration, the wrap angle of the second consumable paper tape on the first consumable is also relatively small. This embodiment also demonstrates that the size of the wrap angle is not related to the location of the middle or end of the extension of the paper feeding channel, but rather to the location of the tape passing point 43.

[0064] Fifth embodiment of the printer See Figure 7 In this embodiment, the first consumable compartment 46 and the second consumable compartment 47 are arranged sequentially along the width direction of the main body, and the two are located at the same position in the length direction of the main body.

[0065] In this embodiment, the conveyor belt passes through point 48, which is also located outside the first region 49.

[0066] Sixth embodiment of the printer See Figure 8 In this embodiment, the first surrounding structure 511 of the first consumable compartment 51 includes the inner wall surface of a regular polygon, and the center of the largest inscribed circle of the regular polygon coincides with the center of the first positioning axis. In this embodiment, the largest concentric circle 51a that can be accommodated is the largest inscribed circle of the regular polygon.

[0067] Seventh embodiment of the printer See Figure 9 In this embodiment, the inner periphery of the first consumable compartment 52 is close to a rectangle, and the largest circle that can be placed in the first consumable compartment 52 and is concentric with the first positioning axis is taken as the largest concentric circle that can be accommodated 52a.

[0068] Printer Eighth Embodiment See Figure 10 In this embodiment, the structure surrounding the first consumable compartment 52 is discontinuous and has an irregular outline. Of course, in this case, it is also possible to identify the largest circle that is large enough to fit into the first consumable compartment 53 and is concentric with the first positioning axis, as the largest concentric circle that can be accommodated 53a. Ninth embodiment of the printer See Figure 11 In this embodiment, the paper tape led out by the second consumable does not intersect with the largest concentric circle 54a that the first consumable compartment 54 can accommodate, and the minimum distance d between the tape passing point 55a and the largest concentric circle 54a is greater than 0. In fact, in this embodiment, the paper tape led out by the second consumable will not come into contact with the first consumable.

[0069] Combination Figures 8 to 10As can be seen from the three embodiments shown, regardless of the surrounding structure of the first consumable compartment or the inner wall of the first consumable compartment, the largest circle that can be placed in the first consumable compartment and is concentric with the first positioning axis can always be determined. Therefore, the largest concentric circle that can be accommodated can always be determined.

[0070] Combination Figures 8 to 11 As can be seen from the four embodiments shown, along the conveyor path of the second consumable lead-out belt, the second consumable lead-out belt has one and only one point that is at the minimum distance from the maximum concentric circle that can be accommodated. Therefore, the point through which the conveyor passes in this invention can also be uniquely determined.

[0071] Printer Tenth Embodiment See Figure 12 In this embodiment, neither the first consumable compartment 61 nor the second consumable compartment 62 needs to pass through each other to connect with the paper feeding channel 63. Instead, they are both directly connected to the paper feeding channel 63. That is, compared with the other embodiments mentioned above, the paper tape led out by the second consumable compartment 62 in this embodiment can directly enter the paper feeding channel 63 without passing through the first consumable compartment 61.

[0072] In this embodiment, the paper feeding channel 63 is disposed between the first consumable compartment 61 and the second consumable compartment 62. More specifically, the paper feeding channel 63 is entirely disposed between the first positioning shaft 611 and the second positioning shaft 621 along the line connecting the axis of the first positioning shaft 611 and the axis of the second positioning shaft 621. The first positioning shaft 611 and the second positioning shaft 621 are arranged sequentially along the length of the main body. Furthermore, in terms of the width of the main body, the first positioning shaft 611 and the second positioning shaft 621 are offset to one side, while the paper feeding channel 63 is offset to the other side.

[0073] When the layout of the paper feed path is not limited by other structures inside the printer, this setup is more conducive to the feeding effect of consumables in the first consumable compartment 61 and the second consumable compartment 62.

[0074] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
