Description

Technical Field

[0001] The invention relates to the field of printers, and in particular to an alternating paper feeding device. Background Art

[0002] At present, there are more and more types of self-service equipment on the market, such as unmanned supermarkets, self-service checkouts, ATM machines, etc., and the usage of receipt printing equipment used in them will also increase, which puts high demands on the unmanned endurance time of receipt printing equipment.

[0003] The existing receipt printer will alarm in advance when the printing paper is about to run out. If the maintenance personnel arrive in time to replace the printing paper, the last large piece will be taken out and cannot be used, causing waste. If they come too late, the printing paper will run out and the machine will be shut down until the maintenance personnel replace the printing paper and restart the machine. This will greatly affect the user experience and reduce the efficiency of self-service equipment.

[0004] In order to reduce maintenance costs and increase the unmanned endurance time of self-service equipment, the technology of the present invention solves the problem of replacing printing paper and wasting the last piece of paper, thereby greatly reducing costs and increasing efficiency. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides an alternate paper feeding device, which can reduce maintenance costs and increase the unmanned endurance time of a receipt printer of a self-service device.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] An alternating paper feeding device comprises a mounting frame, a printing paper roller arranged on the mounting frame and used for loading a printing paper roll, a pre-loaded paper roller arranged on the mounting frame and used for loading a pre-loaded paper roll, and an alternating paper feeder;

[0008] The alternating paper feeder includes a printing base plate, a printing glue shaft disposed above the printing base plate, a pre-installed base plate, a pre-installed glue shaft disposed above the pre-installed base plate, and a driving assembly for driving the printing glue shaft and the pre-installed glue shaft to rotate;

[0009] The printing paper roll is fed into the printer through the printing rubber shaft and the printing bottom plate, and the end of the pre-installed paper roll is clamped between the pre-installed rubber shaft and the pre-installed bottom plate.

[0010] By adopting the above technical solution, the alternate paper feeding device is usually arranged at the paper inlet of the printer and is electrically connected to the alarm system of the printer. The alarm system of the printer usually estimates the remaining paper according to the length of the paper entering the printer.

[0011] The printing channel is between the printing paper roll and the printing base plate, and the pre-installed channel is between the pre-installed glue shaft and the pre-installed base plate; when the remaining printing paper roll is not enough for one receipt, the alarm system of the printer is activated and the driving component is turned on. The driving component drives the printing glue shaft to rotate, and the remaining printing paper is brought out of the printing channel through the printing glue shaft. At the same time, the driving component drives the pre-installed glue shaft to rotate, and the end of the pre-installed paper roll is sent to the printing channel by the pre-installed glue shaft, and then sent to the printer by the printing glue shaft, thereby completing the alternating work of the printing paper roll and the pre-installed paper roll. When the staff comes for maintenance, they only need to move the pre-installed paper roll to the printing paper roller to form a new printing paper roll, and re-install the new pre-installed paper roll on the pre-installed paper roller, and place the end of the pre-installed paper roll in the pre-installed channel;

[0012] In this way, the conflict problem caused by the time when the printing paper roll runs out and the time when the staff performs maintenance can be solved.

[0013] Preferably, an unlocking assembly is provided on the mounting frame, and the unlocking assembly comprises an unlocking motor and an unlocking disc, and the unlocking motor is used to drive the unlocking disc to rotate forward or reverse.

[0014] Preferably, the mounting frame is provided with a seesaw, which is rotatably connected to the mounting frame via a fixed axis, the printing glue shaft is arranged at one end of the seesaw, and the other end of the seesaw is provided with a block pressed against the side wall of the unlocking disk, and the side wall of the unlocking disk is provided with a accommodating groove.

[0015] By adopting the above technical solution, since the pulling speeds of the printing rubber shaft and the printer are usually inconsistent, when the printing rubber shaft delivers the end of the pre-loaded paper roll to the printer, it is best to lift the printing rubber shaft to separate the printing rubber shaft from the pre-loaded paper roll. Therefore, the present invention needs to complete the two actions of lifting and falling of the printing rubber shaft. The specific movement process is as follows: when the stop block abuts against the side wall of the unlocking disc but does not enter the accommodating groove, the printing rubber shaft is in a lifted state, and when the unlocking disc is driven by the unlocking motor to rotate clockwise in the figure, the stop block enters the accommodating groove, and the printing rubber shaft is in a fallen state under the action of its gravity, or a torsion spring is installed at the fixed shaft, and the printing rubber shaft abuts against the printing base plate under the action of the torsion spring.

[0016] Preferably, a first gear is provided at the end of the fixed shaft, a second gear is provided at the end of the printing glue shaft, and a third gear is provided at the end of the pre-installed glue shaft. The second gear and the third gear are both engaged with the first gear, and the driving assembly drives the first gear to rotate.

[0017] By adopting the above technical solution, only one driving component is used to drive the rotation of the printing glue shaft and the pre-installed glue shaft.

[0018] Preferably, the driving assembly comprises a driving motor, an initial gear arranged at an end of the driving motor, and a reduction gear set meshing with the initial gear, and the reduction gear set meshing with the first gear.

[0019] By adopting the above technical solution, the reduction gear set is used to reduce the rotation rate of each gear and increase the torque of the output shaft of the drive motor to prevent the gears from driving the pre-installed glue shaft or the printing glue shaft to rotate too fast and tear the paper roll, or the torque is insufficient and the paper roll cannot be pulled.

[0020] Preferably, one end of the pre-installed base plate is rotatably connected to the mounting frame, and the other end is a free end. The mounting frame is provided with a hook plate in the middle portion which is rotatably connected to the mounting frame. One end of the hook plate hooks the free end of the pre-installed base plate, and the unlocking assembly is located at the other end of the hook plate, and the unlocking assembly and the pre-installed base plate are respectively located on both sides of the hook plate.

[0021] By adopting the above technical solution, when the staff is moving the pre-loaded paper roll from the pre-loaded paper roller to the printing paper roller, the paper roll will be blocked by the pre-loaded bottom plate. Therefore, the pre-loaded bottom plate is unlocked by the unlocking component after the pre-loaded paper roll is fed into the printer, so that the free end of the pre-loaded bottom plate freely hangs down to 90° under the action of gravity, so that the entire paper feed channel is in a free state, and only the printer automatically pulls the paper.

[0022] Preferably, the unlocking disc is provided with a boss at an eccentric position, and when the unlocking motor drives the unlocking disc to rotate, the boss pushes the end of the hook plate to disengage the other end of the hook plate from the free end of the pre-installed base plate.

[0023] By adopting the above technical solution, since the unlocking assembly and the pre-installed base plate are respectively located on both sides of the hook plate, when the boss pushes one end of the hook plate, the other end of the hook plate will move in the direction of the pre-installed base plate, so that the hook plate is separated from the free end of the pre-installed base plate, and the free end of the pre-installed base plate rotates around the rotating end to a vertical state under the action of gravity.

[0024] Preferably, a steering paper roller is provided between the pre-installed paper roller and the pre-installed rubber shaft.

[0025] By adopting the above technical solution, the steering roller is used to adjust the direction of the end of the pre-loaded paper roll so that the end of the pre-loaded paper roll can enter the pre-loading channel horizontally, and it can also prevent the thermal paper from generating friction during the paper feeding process, causing the printed paper surface to become black.

[0026] Preferably, a side of the pre-installed bottom plate close to the pre-installed paper roller is tilted downward to form a guide surface.

[0027] By adopting the above technical solution, it is convenient for the staff to place the end of the pre-installed paper roll between the pre-installed bottom plate and the pre-installed glue shaft.

[0028] The beneficial effects of the present invention are:

[0029] 1. By using the alternating operation of printing paper rolls and pre-installed paper rolls, the optimal maintenance time for staff can be indirectly extended, so that staff can replace new pre-installed paper rolls in a very relaxed time period, thereby improving the self-service efficiency of printing equipment;

[0030] 2. Avoid wasting the last piece of paper;

[0031] 3. The unlocking component is used to simultaneously control the rotation of the pre-installed base plate and the rise and fall of the printing glue shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0047] The alternating paper feeding device provided by the present invention is usually arranged at the paper feed port of the printer and is electrically connected to the alarm system of the printer. The alarm system of the printer usually estimates the remaining paper based on the length of the paper entering the printer. Since the alarm system is electrically connected to the drive component and the unlocking component in the present invention, the technology of realizing the alarm system controlling the drive component and the unlocking component is common knowledge in the field. Therefore, the specific printer alarm system is not disclosed in the present invention.

[0048] An alternate paper feeding device, such as Figure 1 As shown, it includes a mounting frame 1, a printing paper roller 202 arranged on the mounting frame 1 and used for loading a printing paper roll 201, a pre-loaded paper roller 302 arranged on the mounting frame 1 and used for loading a pre-loaded paper roll 301, and an alternating paper feeder 4.

[0049] like Figure 2 and Figure 3 As shown, the alternating paper feeder 4 includes a printing base plate 401, a printing glue shaft 402 arranged above the printing base plate 401, a pre-installed base plate 403, a pre-installed glue shaft 404 arranged above the pre-installed base plate 403, and a driving component 5 for driving the printing glue shaft 402 and the pre-installed glue shaft 404 to rotate.

[0050] The printing paper roll 201 is fed into the printer between the printing glue shaft 402 and the printing bottom plate 401 , and the end of the pre-installed paper roll 301 is clamped between the pre-installed glue shaft 404 and the pre-installed bottom plate 403 .

[0051] The printing passage is between the printing paper roll 201 and the printing bottom plate 401 , and the pre-installing passage is between the pre-installing glue shaft 404 and the pre-installing bottom plate 403 .

[0052] Principle for solving the technical problem of the background technology: when the remaining printing paper roll 201 is not enough for one receipt, the alarm system of the printer is started and the driving component 5 is turned on. The driving component 5 drives the printing glue shaft 402 to rotate, and the remaining printing paper roll 201 will be brought out of the printing channel through the printing glue shaft 402. At the same time, the driving component 5 drives the pre-installed glue shaft 404 to rotate, and the end of the pre-installed paper roll 301 is sent to the printing channel by the pre-installed glue shaft 404, and is sent to the printer by the printing glue shaft 402, thereby completing the alternating work of the printing paper roll 201 and the pre-installed paper roll 301. When the staff comes for maintenance, they only need to move the pre-installed paper roll 301 to the printing paper roller 202 to form a new printing paper roll 201, and then re-install the new pre-installed paper roll 301 on the pre-installed paper roller 302, and place the end of the pre-installed paper roll 301 in the pre-installed channel; in this way, the contradiction problem caused by the different time when the printing paper roll 201 is used up and the maintenance time of the staff can be solved.

[0053] An unlocking assembly 6 is disposed on the mounting frame 1 . The unlocking assembly 6 includes an unlocking motor 601 and an unlocking disc 602 . The unlocking motor 601 is used to drive the unlocking disc 602 to rotate forward or reverse.

[0054] Since the pulling speed of the printing rubber shaft 402 and the printer is usually inconsistent, after the printing rubber shaft 402 delivers the end of the pre-loaded paper roll 301 to the printer, it is best to lift the printing rubber shaft 402 to separate the printing rubber shaft 402 from the pre-loaded paper roll 301. Therefore, the present invention is specifically configured as follows to complete the two actions of lifting and dropping the printing rubber shaft 402.

[0055] like Figure 2 and Figure 4 As shown, the mounting frame 1 is provided with a seesaw 101, which is rotatably connected to the mounting frame 1 via a fixed shaft 102, the printing glue shaft 402 is arranged at one end of the seesaw 101, and the other end of the seesaw 101 is provided with a block 103 pressed against the side wall of the unlocking disk 602, and the side wall of the unlocking disk 602 is provided with a receiving groove 603.

[0056] When the stopper 103 abuts against the side wall of the unlocking disc 602 but does not enter the accommodating groove 603, the printing glue shaft 402 is in a lifted state; when the unlocking disc 602 is driven by the unlocking motor 601 to rotate clockwise in the figure, the stopper 103 enters the accommodating groove 603, and the printing glue shaft 402 is in a falling state under the action of its gravity; or a torsion spring is installed at the fixed shaft 102, and the printing glue shaft 402 abuts against the printing base plate 401 under the action of the torsion spring.

[0057] Since the paper roll 301 will be blocked by the pre-loaded bottom plate 403 when the staff moves the pre-loaded paper roll 301 from the pre-loaded paper roller 302 to the printing paper roller 202, the pre-loaded bottom plate 403 needs to be rotated to a vertical state before the pre-loaded paper roll 301 is moved. After the paper roll replacement work is completed, the pre-loaded bottom plate 403 is adjusted to a horizontal state. For this purpose, the present invention is further arranged as follows.

[0058] like Figure 2 and Figure 5 As shown, one end of the pre-installed base plate 403 is rotatably connected to the mounting frame 1, and the other end is a free end. The mounting frame 1 is provided with a hook plate 104 whose middle part is rotatably connected to the mounting frame 1, and one end of the hook plate 104 is provided with a hook portion 105 for hooking the free end of the pre-installed base plate 403. The unlocking component 6 is located at the other end of the hook plate 104, and the unlocking component 6 and the pre-installed base plate 403 are respectively located on both sides of the hook plate 104; the unlocking disc 602 is provided with a boss 604 at an eccentric position, and when the unlocking motor 601 drives the unlocking disc 602 to rotate, the boss 604 pushes the end of the hook plate 104 to disengage the other end of the hook plate 104 from the free end of the pre-installed base plate 403.

[0059] Since the unlocking assembly 6 and the pre-installed base plate 403 are respectively located on both sides of the hook plate 104, when the boss 604 pushes one end of the hook plate 104, the other end of the hook plate 104 will move in the direction of the pre-installed base plate 403, so that the hook plate 104 is separated from the free end of the pre-installed base plate 403, and the free end of the pre-installed base plate 403 rotates around the rotating end to a vertical state under the action of gravity.

[0060] A steering paper roller 303 is provided between the pre-loaded paper roller 302 and the pre-loaded rubber shaft 404; the steering paper roller 303 is used to adjust the end direction of the pre-loaded paper roll 301 so that the end of the pre-loaded paper roll 301 can enter the pre-loading channel horizontally, and can also prevent the thermal paper from generating friction during the paper feeding process, causing the printed paper surface to become black.

[0061] The side of the pre-installed bottom plate 403 close to the pre-installed paper roll 302 is tilted downward to form a guide surface; this facilitates the staff to place the end of the pre-installed paper roll 301 between the pre-installed bottom plate 403 and the pre-installed glue shaft 404.

[0062] like Figure 2 and Figure 6 As shown, a first gear 106 is provided at the end of the fixed shaft 102, a second gear 107 is provided at the end of the printing glue shaft 402, and a third gear 108 is provided at the end of the pre-installed glue shaft 404. The second gear 107 and the third gear 108 are both engaged with the first gear 106, and the driving component 5 drives the first gear 106 to rotate; only one driving component 5 is used to drive the rotation of the printing glue shaft 402 and the pre-installed glue shaft 404.

[0063] The driving assembly 5 includes a driving motor 501, an initial gear 502 arranged at the end of the driving motor 501, and a reduction gear set 503 meshing with the initial gear 502, and the reduction gear set 503 meshing with the first gear 106; the reduction gear set 503 is used to reduce the rotation rate of each gear to prevent the gear from driving the pre-installed glue shaft 404 or the printing glue shaft 402 to rotate too fast and tear the paper roll.

[0064] In order to better understand the complete movement process in the present invention, it is further described as follows.

[0065] Figure 1 and Figure 2 The conventional use state of the present invention is shown, that is, the end of the pre-installed paper roll 301 is located between the pre-installed base plate 403 and the pre-installed glue shaft 404, and the printing paper roll 201 is fed into the printer through the printing base plate 401 and the printing glue shaft 402 using the pulling force of the printer itself.

[0066] When the alarm system of the printer detects that the remaining printing paper is not enough for the next receipt, the alarm system sends an electrical signal to the driving component 5, so that the driving component 5 drives the printing glue shaft 402 to rotate.

[0067] At the same time, the alarm system sends an electrical signal to the unlocking assembly 6, causing the unlocking motor 601 to move with the unlocking disc 602. Figure 2 The state is changed from Figure 2 Go to Figure 4 , the printing rubber shaft 402 falls under its own gravity and presses against the remaining printing paper roll 201, and the remaining printing paper roll 201 is moved out of the printing channel (i.e., between the printing base plate 401 and the printing rubber shaft 402); if the printing rubber shaft 402 cannot fall by its own gravity, a torsion spring can be arranged outside the fixed shaft 102, and the force of the torsion spring drives the printing rubber shaft 402 to move toward the printing base plate 401.

[0068] In addition, the driving assembly 5 also drives the pre-installed glue shaft 404 to rotate, and the pre-installed glue shaft 404 delivers the end of the pre-installed paper roll 301 to the printer through the printing channel.

[0069] After the remaining printing paper roll 201 is moved out of the printing channel and the end of the pre-installed paper roll 301 is sent to the printer through the printing channel, the unlocking disc 602 rotates counterclockwise and the printing rubber shaft 402 rises.

[0070] The time period from the beginning of using the pre-installed paper roll 301 to the end of using the pre-installed paper roll 301 is the effective time period during which the staff can come to add a new paper roll.

[0071] The staff first uses the unlocking motor 601 to drive the unlocking disc 602 to Figure 2The hook plate 104 rotates counterclockwise, and the free end of the pre-installed bottom plate 403 is separated from the hook portion 105 of the hook plate 104. The pre-installed bottom plate 403 rotates around the rotating end to a vertical state, that is, from Figures 2 to 5 state, at this time the staff can move the preloaded paper roll 301 in use from the preloaded paper roller 302 to the printing paper roller 202, so that the original preloaded paper roll 301 becomes the new printing paper roll 201, and then add a new preloaded paper roll 301 to the preloaded paper roller 302, and place the end of the preloaded paper roll 301 between the preloaded bottom plate 403 and the preloaded rubber shaft 404.

[0072] At this point, the alternating operation of the pre-installed paper roll 301 and the printing paper roll 201 is completed.

[0073] The above is a specific description of the preferred implementation of the present invention, but the invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
