Description

Technical Field

[0001] The present invention relates to the technical field of printers, and in particular to a document printer which is convenient for archiving. Background Art

[0002] When printing book covers, the conventional practice is to carefully separate the cover from the book body and lay it flat. After that, the cover is placed in a standard printing press for printing. After printing, the next step is to glue the cover back into place. However, this separation and bonding process has several problems. First, the cover is prone to creases during the separation process, which affects the appearance. Second, it is impossible to ensure that the cover is not damaged during separation, which increases the risk of printing. Finally, although glue can bond the cover, this method cannot ensure the binding quality of the cover, and wrinkles or other unevenness may occur, which will affect the overall appearance of the book. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a document printer which is convenient for printing filing marks on books without unpacking the books.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0009] When the lifting sensing module senses that the print head has dropped to the lowest value, the lifting driving member stops driving the print head to drop or drives the print head to rise;

[0010] The lateral movement sensing module senses that the print head moves to the edge of the gantry or the location of the positioning module, and the lateral movement driving member stops driving the print head to move or drives the print head to move in the reverse direction.

The ascending sensing group is arranged on the lifting driving member and the print head to sense the maximum value of the rise of the print head, and the descending sensing group is arranged on the print head to sense the minimum value of the descent of the print head.

[0012] In the document printer as described above, the rising sensing group includes a first photoelectric sensor fixed on the print head and a first blocking member fixed on the print head. When the lifting drive member drives the print head to rise, the first blocking member enters into the sensing area of ​​the first photoelectric sensor.

[0013] In the document printer as described above, the descent sensing group includes a pressure limit and a second photoelectric sensor. The pressure limit is retractably arranged on the print head, and the second photoelectric sensor is arranged on the print head.

[0024] When printing, the book is placed on the shelf and under the gantry, the positioning module locates the pre-printing position, the transverse driving component drives the print head to move transversely to above the pre-printing position, and then the lifting driving component drives the print head to descend. The lifting sensing module senses that the print head is above the book, and the lifting sensing module sends a signal to the lifting driving component, so that the lifting driving component stops driving the print head to continue to descend. After the print head finishes printing, the lifting driving component drives the print head to reset, and then the transverse driving component drives the print head to move transversely to the edge position of the gantry to complete an archiving printing job. The document printer in the present invention can directly print archiving information on the cover of the book without repeatedly disassembling and assembling the book, thereby improving the efficiency of archiving.

[0044] 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.

[0045] Reference Figures 1 to 3 , a document printer convenient for filing, comprising a storage plate 5, a gantry 6, a print head 41, a lifting drive member 42, a lateral movement drive member 43, a lifting sensing module, a positioning module 2 and a lateral movement sensing module;

[0046] The gantry 6 is fixed on the storage plate 5, the fixed end of the lifting drive member 42 is slidably arranged on the gantry 6, the print head 41 is transmission-connected with the output end of the lifting drive member 42, the fixed end of the transverse drive member 43 is arranged on the gantry 6, the output end of the transverse drive member 43 is transmission-connected with the fixed end of the lifting drive member 42, the transverse drive member 43 is used to drive the lifting drive member 42 and the print head 41 to reciprocate and transversely move on the gantry 6, the lifting sensing module is arranged on the print head 41 and the lifting drive member 42, the lifting sensing module is in communication with the lifting drive member 42, and the transverse sensing module is in communication with the transverse drive member 43;

[0047] The positioning module 2 is arranged on the gantry 6;

[0048] When the lifting sensing module senses that the print head 41 has risen to the highest value, the lifting driving member 42 stops driving the print head 41 to rise or drives the print head 41 to fall;

[0049] When the lifting sensing module senses that the print head 41 has dropped to the lowest value, the lifting driving member 42 stops driving the print head 41 to drop or drives the print head 41 to rise;

[0050] The lateral movement sensing module senses that the print head 41 moves to the edge of the gantry 6 or the positioning module 2 , and the lateral movement driving member 43 stops driving the print head 41 to move or drives the print head 41 to move in the reverse direction.

[0051] When printing, the book is placed on the storage plate 5 and under the gantry 6, the positioning module 2 positions the pre-printing position, the transverse driving component 43 drives the print head 41 to move transversely to above the pre-printing position, and then the lifting driving component 42 drives the print head 41 to descend. The lifting sensing module senses that the print head 41 is above the book, and the lifting sensing module sends a signal to the lifting driving component 42, so that the lifting driving component 42 stops driving the print head 41 to continue to descend. After the print head 41 finishes printing, the lifting driving component 42 drives the print head 41 to reset, and then the transverse driving component 43 drives the print head 41 to move transversely to the edge of the gantry 6 to complete an archiving printing job; the document printer in the present invention can directly print archiving information on the cover of the book without repeatedly disassembling and assembling the book, which can improve the efficiency of archiving.

[0052] Compared with the prior art, in which cover information needs to be printed separately on the cover paper and then bound, the archiving printer in this embodiment does not need to be disassembled when used; there is no need to manually write on the cover or stick label paper, which can speed up the progress of book archiving.

[0053] Of course, the archiving printer in this embodiment is also suitable for printing document contents in books. Printing can be done by turning pages without disassembling the book, which is convenient and fast.

[0054] Reference Figure 2 In one embodiment, the length of the storage plate 5 is greater than the width of the gantry 6 to improve the stability of the books placed on the storage plate 5, and also to prevent the center of gravity of the books from being unstable and shifting when the print head 41 is lowered for printing, thereby affecting the printing effect.

[0055] Specifically, the length of the storage plate 5 is greater than the length of the book to be printed.

[0056] Reference Figure 2 Specifically, in one embodiment, the gantry 6 includes a left support member 62, a right support member 63 and a slide rail 64;

[0057] The left support member 62 is disposed on the left side of the slide rail 64 , the right support member 63 is disposed on the right side of the slide rail 64 , and the print head 41 slides on the slide rail 64 .

[0058] On one hand, the left support member 62 and the right support member 63 are used to raise the slide rail 64, thereby lifting the print head 41; on the other hand, the left support member 62 and the right support member 63 can stably install the slide rail 64, ensuring that the print head 41 moves to any position of the slide rail 64 without the slide rail 64 shifting, thereby keeping the center of gravity of the print head 41 stable, avoiding affecting the movement of the print head 41 and affecting the printing effect of the print head 41.

[0059] Specifically, the left support member 62 and the right support member 63 are arranged parallel to each other, and the slide rail 64 is parallel to the horizontal line.

[0060] Reference Figures 2 to 3 Specifically, the gantry 6 is provided with a transmission belt 65, a driving wheel 66 and a driven wheel 67;

[0061] The transverse driving member 43 is in driving connection with the print head 41, and the driving wheel 66 is fixedly connected with the output end of the transverse driving member 43;

[0062] The driven wheel 67 is rotatably disposed on a side of the left support member 62 facing away from the right support member 63;

[0063] One end of the slide rail 64 is fixed to the left support member 62, and the other end is fixed to the right support member 63;

[0064] The transmission belt 65 is meshed with the driving wheel 66 and the driven wheel 67 respectively. The lifting drive member 42 is fixedly connected to the transmission belt 65 and is slidably disposed on the slide rail 64 .

[0065] The transverse driving member 43 drives the driving wheel 66 to rotate, the driving wheel 66 drives the transmission belt 65 to rotate, and the transmission belt 65 drives the passive wheel 67 to move synchronously. At the same time, the lifting driving member 42 moves along with the transmission belt 65, and the lifting driving member 42 moves transversely on the slide rail 64.

[0066] As an example, the lateral driving member 43 is connected to the print head 41 by gear transmission, chain transmission, belt transmission, screw transmission or any combination thereof without contradiction.

[0067] The transverse drive member 43 is used to replace the movement of workers, so as to further improve the automation level of the printer, reduce human intervention, and improve the user experience.

[0068] Reference Figure 4 as well as Figure 6 Specifically, a front groove 641 and a rear groove 642 are provided on the slide rail 64, and the transmission belt 65 is installed in the front groove 641 and the rear groove 642, which can determine the moving path of the transmission belt 65 and prevent the transmission belt 65 from being separated from the driving wheel 66 and the passive wheel 67, affecting the stability of driving the lifting drive member 42 to move.

[0069] Specifically, an upper pulley 13 and a lower pulley 14 are installed at the rear side of the lifting drive member 42, and the slide rail 64 further includes an upper groove 643 and a lower groove 644, in which the upper pulley 13 is slidably disposed, and the lower pulley 14 is slidably disposed in the upper groove 643, and the lower pulley 14 is slidably disposed in the lower groove 644. This is equivalent to the upper pulley 13 and the lower pulley 14 clamping the slide rail 64, which can reduce the probability of the upper pulley 13 and the lower pulley 14 detaching from the slide rail 64; when the lifting drive member 42 is printing, the lifting drive member 42 is pushed upward, and at this time, since the lower pulley 14 abuts against the inner wall of the lower groove 644, the lower pulley 14 cannot detach from the lower groove 644, further improving the stability of the lifting drive member 42 during movement and printing.

[0070] More specifically, there are more than two upper pulleys 13 and more than two lower pulleys 14. The lifting drive member 42 has more supporting points on the slide rail 64, and has stronger stability during movement and printing.

[0071] Reference Figure 4 , Figure 5 , Figure 6 In one embodiment, the lifting sensing module includes an ascending sensing group 11 and a descending sensing group 12. The ascending sensing group 11 is arranged on the lifting driving member 42 and the print head 41 to sense the maximum value of the rise of the print head 41. The descending sensing group 12 is arranged on the print head 41 to sense the minimum value of the descent of the print head 41.

[0072] Specifically, the rising sensing group 11 includes a first photoelectric sensor 111 fixed on the print head 41 and a first blocking member 112 fixed on the print head 41. When the lifting drive member 42 drives the print head 41 to rise, the first blocking member 112 enters into the sensing area of ​​the first photoelectric sensor 111.

[0073] Specifically, the descent sensing group 12 includes a pressure limit 121 and a second photoelectric sensor 122. The pressure limit 121 is retractably arranged on the print head 41, and the second photoelectric sensor 122 is arranged on the print head 41. When the print head 41 descends, the pressure limit 121 is pushed upward and enters the sensing range of the second photoelectric sensor 122.

[0074] In one embodiment, the print head 41 includes a shell 44, in which a fixed bracket 45 is provided; a through hole 441 is provided on the shell 44, and the pressure limit 121 is set through the through hole 441; along the extension and retraction direction of the pressure limit 121, the second photoelectric sensor 122 is fixed on the fixed bracket 45, and when the pressure limit 121 retracts, the pressure limit 121 enters the sensing area of ​​the second photoelectric sensor 122, and when the pressure limit 121 extends, the pressure limit 121 leaves the sensing area of ​​the second photoelectric sensor 122.

[0075] It can be understood that the sensing port of the second photoelectric sensor 122 is arranged toward the expansion and contraction direction of the pressure limiter 121 .

[0076] Reference Figure 5 Specifically, the fixing bracket 45 includes a secondary left support member 451, a secondary right support member 452, and a secondary transverse support member 453, and the second photoelectric sensor 122 is disposed on the top of the secondary left support member 451 and the secondary right support member 452;

[0077] One end of the secondary lateral support member 453 is connected to the secondary left support member 451 , and the other end is connected to the secondary right support member 452 ;

[0078] The pressure limiter 121 is provided with a step structure 1211 and a limiting structure 1212 located in the housing 44. The limiting structure 1212 is arranged adjacent to the through hole 441. The limiting structure 1212 is used to prevent the pressure limiter 121 from falling off from the through hole 441. The step structure 1211 and the limiting structure 1212 are arranged adjacent to each other.

[0079] A spring (not shown) is disposed in the housing 44 , one end of the spring abuts against the secondary transverse support member 453 , and the other end of the spring is disposed on the step structure 1211 .

[0080] When printing, the book pushes the pressure limit 121 to retract, and the spring is squeezed. At this time, the pressure limit 121 is in the sensing area of ​​the second photoelectric sensor 122. When the print head 41 is lifted, the spring stretches, driving the pressure limit 121 to extend and move away from the printing area of ​​the second photoelectric sensor 122. With this arrangement, the limiting structure 1212 can stabilize the expansion and contraction amount of the pressure limit 121 and reduce the occurrence of the pressure limit 121 getting stuck in the housing 44.

[0081] Specifically, a through slot 4531 is formed on the secondary transverse support member 453 , and the pressure limiter 121 always runs through the through slot 4531 .

[0082] The through groove 4531 cooperates with the through hole 441 to completely determine the moving direction of the pressure limiter 121 , thereby preventing the pressure limiter 121 from being offset at one end of the housing 44 and causing the pressure limiter 121 to fail.

[0083] More specifically, the length of the pressure limiter 121 in the housing 44 is greater than the length from the secondary transverse support 453 to the inner wall of the housing 44 to ensure that the pressure limiter 121 will not be separated from the secondary transverse support 453 .

[0084] Reference Figure 2 , Figure 3 Specifically, the gantry 6 includes a transverse support rod 61, and the positioning module 2 includes a third photoelectric sensor 201 provided on the lifting drive member 42 and a third blocking member 202 slidably provided on the transverse support rod 61;

[0085] When the third photoelectric sensor 201 slides to the side of the third blocking member 202 along with the lifting drive member 42, the third blocking member 202 is located in the sensing area of ​​the third photoelectric sensor 201, and at this time, the lifting drive member 42 drives the print head 41 to descend.

[0086] When the print head 41 slides, the third photoelectric sensor 201 moves to the third blocking member 202, and the print head 41 performs a printing operation.

[0087] Among them, the third photoelectric sensor 201 adopts optical signal transmission, has high sensitivity, is not easily interfered by electromagnetic interference and stray light, has high anti-interference ability, and has strong working stability; and the third photoelectric sensor 201 and the third blocking member 202 are small in size, have great space advantages, and are easy to install.

[0088] More specifically, a limiting column 611 is provided on the transverse support rod 61, and the positioning module 2 includes a position marking member 21 and a moving block 22;

[0089] The moving block 22 is provided with a moving limiting groove 221, and the limiting column 611 is located in the moving limiting groove 221;

[0090] The moving block 22 slides on the transverse support rod 61 along the moving limiting groove 221, and the maximum moving distance is limited by the limiting column 611;

[0091] The position marking member 21 is fixedly connected to the moving block 22 , and the position marking member 21 is used to emit a light mark to a position to be printed.

[0092] When in use, the book to be printed is placed under the gantry 6, the position of the positioning module 2 is adjusted to locate the position to be printed, the printer is started, and when the print head 41 moves to the positioning module 2, the print head 41 performs a printing operation.

[0093] It can be understood that the movable limiting groove 221 is a long groove, and the movable limiting column 611 abuts against the end of the long groove to limit the movable block 22 and prevent the movable block 22 from falling from the transverse support member 24.

[0094] Specifically, there are two limiting posts 611 and two movable limiting grooves 221 , and the two movable limiting grooves 221 are respectively arranged on both sides of the position marking member 21 , and one movable limiting groove 221 passes through one limiting post 611 .

[0095] It is understandable that the position marker 21 can emit a medium onto the book to assist the user in determining the part to be printed. For example, if the position marker 21 is an infrared light emitter, it can emit infrared marking light onto the book. Of course, the light emitted by the position marker 21 can also be green, purple, blue, or any other light that can form a sharp contrast with the part to be printed.

[0096] More specifically, the moving block 22 is provided with a power assisting member 222 for assisting in moving the moving block 22 .

[0097] When in use, the moving block 22 is manually moved to make the position marker 21 move synchronously, and the moving block 22 moves relative to the limiting column 611 to a suitable position, and the moving block 22 is stopped to adjust the marking point of the position marker 21.

[0098] Reference Figure 1 and Figure 2 In one embodiment, a nozzle 411 for inkjet is protrudingly provided on the print head 41, and a nozzle cover 51 is provided on one side of the placement plate 5. The nozzle cover 51 is arranged outside the nozzle 411 to reduce the volatilization of ink in the nozzle 411 and reduce the influence of the volatilization of ink at the nozzle 411 on the printing effect.

[0099] More specifically, the nozzle cover 51 is connected to the storage plate 5 via a spring 52, so that the nozzle cover 51 is elastic along the extension and contraction direction of the print head 41, thereby avoiding the possibility of the nozzle 411 being damaged due to the rigid contact between the nozzle cover 51 and the nozzle 411.

[0100] In one embodiment, it also includes a shell 7, which is located on the storage plate 5 and is arranged outside the gantry 6, the print head 41, the lifting drive member 42, the transverse driving member 43, the lifting sensing module, the positioning module 2 and the transverse sensing module. The shell 7 is provided with a front slot 71 and a rear slot 72 that are relatively arranged, and the front slot 71 and the rear slot 72 are used for printing documents to pass through and be placed.

[0101] During printing, the book to be printed is put into the front slot 71 of the gantry 6 and passes through the rear slot 72. The part to be printed is adjusted to the bottom of the gantry 6. The rear slot 72 is arranged in this way, so that more space is left to adjust the position of the book to be printed.

[0102] Reference Figure 1 In one embodiment, a control panel 73 is fixed on the housing 7, and the control panel 73 is in communication with the print head 41. By inputting printing information on the control panel 73, the print head 41 prints the corresponding information.

[0103] Reference Figures 7 to 10 In one embodiment, the lateral movement sensing module includes a left sensing group 31 and a right sensing group 32.

[0104] The left sensing group 31 is disposed on the left supporting member 62 and is used to sense whether the lifting driving member 42 moves to one side of the left supporting member 62;

[0105] The right sensing group 32 is disposed on the right supporting member 63 and is used to sense whether the lifting driving member 42 moves to one side of the right supporting member 63;

[0106] The left sensing group 31 and the right sensing group 32 are both in communication with the transverse driving member 43. When the lifting driving member 42 moves to one side of the left supporting member 62 or the right supporting member 63, the transverse driving member 43 stops driving the lifting driving member 42 or drives the lifting driving member 42 to move in the reverse direction.

[0107] The working principle of this embodiment is as follows: the transverse driving member 43 rotates forward, driving the lifting driving member 42 to move toward the left support member 62. When the lifting driving member 42 moves to the side of the left support member 62, the transverse driving member 43 can stop driving the lifting driving member 42, and the lifting driving member 42 can perform printing operations or use this state as the return state of the lifting driving member 42, or the transverse driving member 43 reverses, driving the lifting driving member 42 to move toward the right support member 63, until the lifting driving member 42 moves to the side of the right support member 63.

[0108] It can be understood that the forward and reverse rotations of the above-mentioned transverse driving member 43 are only used to indicate that the transverse driving member 43 drives the lifting driving member 42 to move in the opposite state of motion; it can also be that when the transverse driving member 43 is reversed, the lifting driving member 42 moves toward the right support member 63, and when the transverse driving member 43 is rotated forward, the lifting driving member 42 moves toward the left support member 62.

[0109] The transverse driving member 43 drives the lifting driving member 42 to move back and forth transversely on the slide rail 64. The left sensing group 31 and the right sensing group 32 are both in communication with the transverse driving member 43. When the lifting driving member 42 moves to the side of the left support member 62 or the right support member 63, the transverse driving member 43 stops driving the lifting driving member 42 or drives the lifting driving member 42 to move in the opposite direction, thereby avoiding the lifting driving member 42 from colliding with the left support member 62 or the right support member 63, causing the position of the lifting driving member 42 to shift, and ensuring that the lifting driving member 42 moves stably on the secondary transverse support member 453, thereby ensuring good printing effect and printing quality.

[0110] In one embodiment, the left sensing group 31 includes a left photoelectric sensor 311 and a left shielding member 312 disposed on the left side of the lifting drive member 42, and the left photoelectric sensor 311 is disposed on the top of the left support member 62;

[0111] When the lifting drive member 42 moves toward the left support member 62, the left shielding member 312 moves synchronously until the left shielding member 312 intersects with the left photoelectric sensor 311, and the transverse driving member 43 stops driving the lifting drive member 42 to move or drives the lifting drive member 42 to move in the opposite direction.

[0112] In one embodiment, the right sensing group 32 includes a right photoelectric sensor 321 and a right shielding member 322 disposed on the right side of the lifting drive member 42;

[0113] The right photoelectric sensor 321 is disposed on a surface of the right support member 63 facing away from the left support member 62;

[0114] A right slot 631 is formed on the right support member 63 adjacent to the right photoelectric sensor 321 , and the right slot 631 is used for the right shielding member 322 to pass through.

[0115] When the lifting drive member 42 moves toward the right support member 63, the right shielding member 322 moves synchronously until the right shielding member 322 intersects with the right photoelectric sensor 321, and the transverse driving member 43 stops driving the lifting drive member 42 to move or drives the lifting drive member 42 to move in the opposite direction.

[0116] Among them, the right photoelectric sensor 321 is arranged on the side of the right support member 63 facing away from the left support member 62. Compared with the right photoelectric sensor 321 being arranged on the side of the right support member 63 facing the left support member 62, the moving distance of the lifting drive member 42 in the latter structure is shorter, while that in the former is longer. Therefore, this solution can further expand the printing range of the lifting drive member 42.

[0117] In one embodiment, a mounting seat 632 is provided on the top of the right support member 63 , and the fixed end of the transverse driving member 43 is fixed on the mounting seat 632 .

[0118] From the above structure, it can be known that the weight of the secondary transverse support member 453, the lifting drive member 42, the left sensing group 31 and the right sensing group 32 are all transferred to the load-bearing books through the left support member 62 and the right support member 63. A mounting seat 632 is set on the top of the right support member 63. The right support member 63 directly bears the gravity of the transverse driving member 43. The right support member 63 has fewer stress concentration points and better pressure resistance, which can make the printer more stable and have a longer service life.

[0119] 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.
