The directional terms used are used to illustrate and understand the present invention, but not to limit the present invention.

[0033] The terms "first", "second", etc. in the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, and should not be used as a limitation on the order of precedence.

[0034] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense. For example, the connection can be a detachable connection or a connection of an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Some label printers can directly output peeled label paper, and are also equipped with a label receiving mechanism to receive the label paper, but there are technical problems such as poor coordination between modules and low efficiency.

[0036] The following is a first embodiment of a printer interface provided by the present invention that can solve the above technical problems.

[0037] Please refer to Figure 1 ,in Figure 1 FIG. 1 is a schematic structural diagram of a first embodiment of a printer of the present invention.

[0038] In the figures, structurally similar elements are denoted by the same reference numerals.

[0039] The present invention provides a printer, which comprises a printer body 11, a label receiving module 12, a manipulator and a scanning module. The printer body 11, the label receiving module 12, the manipulator and the scanning module are all connected to the same controller.

[0040] The printer body 11 is used to print the original label paper. A peeler is provided on the printer body 11 (the peeler is an existing structure, which can be referred to the supermarket weighing equipment to output price label paper, and will not be described here). It can peel the original label paper from the release paper to form the label paper to be pasted. One side of the printer body 11 is provided with an output port for outputting the label paper to be pasted.

[0041] The label receiving module 12 is docked at one side of the output port. The label receiving module 12 includes a transport platform. A sensor 127 for sensing the label paper to be pasted is arranged below the transport platform. The transport platform receives the label paper to be pasted and transports it to a set position for the robot to grab. The scanning module is movably arranged above the label receiving module 12 to scan the label paper to be pasted moving on the transport platform. The robot grabs and labels the label paper according to the scanning information of the label paper to be pasted by the scanning module. The scanning module can scan the label paper to be pasted moving on the transport platform. The scanning work is completed when the label paper to be pasted moves into place on the label receiving module. Once the transport platform stops, the robot can immediately perform the grabbing operation, which is highly efficient.

[0042] The sensor 127 in this embodiment is arranged at an end away from the printer body 11, so that when sensing the label paper to be attached, the controller can control the label receiving module 12 to stop through the sensing signal of the sensor 127, wherein the controller can control the label receiving module 12 to operate according to the output action signal of the printer. It is understandable that the sensor can also be arranged at an end close to the printer, and when the sensor senses the label paper to be attached, the label receiving module can be controlled to automatically stop after running a certain stroke.

[0043] Please refer to Figure 5 In this embodiment, the transport platform includes a main frame 121, a driving roller 122, a driven roller 123, a motor 124 and a belt 125. The driving roller 122 and the driven roller 123 are rotatably arranged on the main frame 121, the motor 124 is in transmission connection with the driving roller 122, and the belt 125 is connected between the driving roller 122 and the driven roller 123.

[0044] Please refer to Figure 1The scanning module includes a fixed frame 132, a transmission mechanism, a first elastic member and a scanner 131. The scanner 131 is slidably set on the fixed frame 132, and the scanner 131 scans downward. The transmission mechanism is connected to the active roller 122, and the transmission mechanism includes a driving block 1341a for driving the scanner 131 to slide. The driving block 1341a drives the scanner 131 to move synchronously with the label paper to be attached on the transport platform. During the synchronous movement, the scanner 131 can scan the label paper to be attached. The first elastic member is set between the scanner 131 and the fixed frame 132, and the first elastic member is used to drive the scanner 131 to slide and reset in a direction close to the printer body 11.

[0045] Snap-on blocks 1211 are disposed at both ends of the main frame 121 , and the bottom end of the fixing frame 132 is fixedly sleeved with the snap-on blocks 1211 .

[0046] In this embodiment, the scanner 131 is arranged on the sliding plate 133, and the sliding plate 133 is slidably connected to the fixed frame 132, so the first elastic member can also be connected to the sliding plate 133. The first elastic member in this embodiment is preferably an elastic member structure with a spring (similar to the contraction structure of a tape measure), and the first elastic member may include a shell, a spring, a rotating member, and a connecting rope. The shell is fixed on the fixed frame 132, and the spring and the rotating member are arranged in the shell. The spring is used to drive the rotating member to rotate and reset. The connecting rope is wound and connected to the rotating member, and one end of the connecting rope extends out of the shell and is connected to the scanner 131 or the sliding plate. The elastic restoring force of the first elastic member of this structure is stable, and the telescopic stroke is relatively long.

[0047] Please refer to Figure 1 , Figure 2 as well as Figure 3 The transmission mechanism in this embodiment includes a direction-changing roller and a transmission belt 134. The two direction-changing rollers are connected to a fixed frame 132 (such as Figure 1 The transmission belt 134 is connected to the active roller 122 (one end of the active roller 122 passes through the main frame 121 and is connected to a transmission wheel) and the direction-changing roller. The portion of the transmission belt between the two direction-changing rollers is parallel to the sliding track of the scanner 131. The driving block 1341a is connected to the side of the transmission belt 134 close to the scanner 131. The transmission belt 134 is preset with multiple driving blocks 1341a.

[0048] Please refer to Figure 4 The transmission belt 134 in this embodiment is divided into a first functional area 1342 and a second functional area 1343 along the length direction line. The first functional area 1342 is provided with a first tooth portion, and the change-direction roller and the active roller 122 are provided with a second tooth portion for meshing with the first tooth portion, thereby forming a better transmission effect. The second functional area 1343 is a smooth surface.

[0049] A limiting plate 136 is disposed on one side of the fixing frame 132, and the limiting plate 136 wraps and positions the second functional area 1343 of the partial transmission belt between the two change-direction rollers, thereby enhancing the stability of the transmission belt 134 and ensuring that the driving block 1341a stably drives the scanner 131 to slide.

[0050] Please refer to Figure 2 and Figure 3 In this embodiment, a baffle 1331 corresponding to the driving block 1341a is provided on one side of the scanner 131. Compared with the scanner 131, the baffle 1331 is smaller in size and is convenient for extension, and is also convenient for the driving block 1341a to be opposite or misaligned with the baffle 1331. A change-of-direction roller away from the printer body 11 is a movable change-of-direction roller 135a, which is in sliding contact with the fixed frame 132, and the sliding direction of the movable change-of-direction roller 135a is in the vertical direction. A limit ring 1372 is provided on the movable change-of-direction roller 135a, and the limit ring 1372 is used to limit the connection between the transmission belt 134 and the movable change-of-direction roller 135a.

[0051] The movable direction-changing roller 135a includes a driving position and an unlocking position on the sliding track. When the movable direction-changing roller 135a is in the driving position, the driving block 1341a contacts the baffle 1331, so that the driving block 1341a can drive the scanner 131 to slide. When the movable direction-changing roller 135a is in the unlocking position, the driving block 1341a avoids the baffle 1331, and the driving block 1341a releases the drive to the scanner 131.

[0052] A second elastic member 1374 is arranged between the movable direction-changing roller 135a and the fixed frame 132. The second elastic member 1374 is used to squeeze the movable direction-changing roller 135a and keep it in the driving position. A first pressure block 1371 that can be squeezed by the scanner 131 is arranged at the end of the fixed frame 132 away from the printer body 11. The first pressure block 1371 is connected to the movable direction-changing roller 135a. The scanner 131 slides and squeezes the first pressure block 1371 to make the movable direction-changing roller 135a slide to the unlocking position. Then, the scanner 131 can slide to the end close to the printer body 11 under the elastic force of the first elastic member to perform the next scanning operation.

[0053] In this embodiment, the movable direction-changing roller 135 a is connected to the first pressure block 1371 and the limiting ring 1372 as a whole through the connecting plate 1373 , and the whole is slidably arranged relative to the fixing frame 132 .

[0054] It is understandable that, since the scanner 131 can be arranged on the sliding plate 133, it is not necessary for the scanner 131 itself to press the first pressure block 1371. In this embodiment, a second pressing block 1332 for pressing the first pressure block 1371 can be arranged on one side of the sliding plate 133. Before the second pressing block 1332 presses and contacts the first pressure block 1371, the scanner 131 completes the scanning work. When the second pressing block 1332 presses the first pressure block 1371, the change-direction roller 135a and the limit ring 1372 will also slide downward at the same time, and the limit ring 1372 will press the transmission belt 134 to move downward, thereby causing the driving block 1341a to be misaligned with the baffle 1331 and then to be out of contact.

[0055] Please refer to Figure 3 Preferably, a vertical slide groove ( Figure 3 The middle slide groove is located on the right end surface of the baffle 1331 (not shown), and the driving block 1341a is provided with a slide bar 13411 corresponding to the slide groove. The cooperation between the slide bar 13411 and the slide groove enables the driving block 1341a to drive the baffle 1331 more stably. The bottom end of the slide groove penetrates the bottom surface of the baffle, so that when the driving block 1341a and the baffle 1331 are dislocated and separated later, the slide bar 13411 can slide out of the slide groove.

[0056] Please refer to Fig. 9 The manipulator can perform XYZ and rotation functions. The various motion structures of the manipulator are relatively mature and will not be described in detail here. The gripping part 16 of the manipulator includes a suction plate 161 and a sponge 162 surrounding the suction plate 161. The suction plate 161 is provided with a plurality of suction holes, which are connected to a vacuum device for suction. The surface of the sponge 162 protrudes from the suction surface of the suction plate 161. The sponge 162 enables the gripping part 16 to more gently grip the label paper to be pasted, and during labeling, the label paper to be pasted can be better attached to an uneven surface.

[0057] Preferably, the gripping portion 16 includes a plurality of suction plates 161 , and a sponge 162 is distributed around each suction plate 161 .

[0058] The main frame 121 in this embodiment is provided with a support block 126 , which runs through the inner side of the belt 125 and is used to provide support when the robot grabs the label paper to be attached, so that the grabbing is flat and convenient for subsequent labeling operations.

[0059] Please refer to Figure 1 and Figure 5 The printer body 11 and the label receiving module 12 are both arranged on the same base frame 14. The printer also includes an adjustment frame, which includes a fixed plate 151, a lifting plate 152, a lifting shaft 154, a lifting locking member 156, a sliding seat 153 and a sliding locking member 155.

[0060] The fixed plate 151 is fixedly connected to the base frame 14, one end of the lifting locking piece 156 is fixedly connected to the fixed plate 151, the lifting shaft 154 slides through the fixed plate 151 and the lifting locking piece 156, the lifting plate 152 is connected to the top end of the lifting shaft 154, the sliding seat 153 is slidably arranged relative to the lifting plate 152, the sliding locking piece 155 is fixedly connected to the lifting plate 152, and the sliding locking piece 155 is used to lock and limit the sliding of the sliding seat 153.

[0061] The sliding seat 153 in this embodiment includes a vertical plate and a horizontal plate connected to the lifting plate 152, the vertical plate is connected to one end of the horizontal plate, and the transport platform is connected to the vertical plate. The sliding seat 153 is connected to a linear guide rail, and the linear guide rail is set on the lifting plate 152.

[0062] By adjusting the sliding seat 153 away from the printer, it is convenient to change the label of the printer body 11. By adjusting the height of the lifting plate, the label receiving module can be adjusted to adapt to the printer body 11 to better receive the label paper to be pasted.

[0063] When the printer of the present invention is used, the printer body 11 prints the original label paper, and then the original label paper is peeled off from the release paper to form the label paper to be pasted, and the label paper to be pasted is output from the output port of the printer body 11, and then begins to be received by the belt 125. The spacing between the multiple driving blocks 1341a on the transmission belt 134 can be preset. When the label paper to be pasted is transported a certain distance by the belt 125 and the scanner 131 can scan the label paper to be pasted, the driving block 1341a will contact the baffle 1331 (that is, the driving block 1341a can run empty for a short distance), and then the driving block 1341a drives the scanner 131 to move synchronously with the label paper to be pasted at the same speed.

[0064] Before the label paper to be attached moves to the label receiving module, the scanner 131 will complete the scanning work. The second squeezing block 1332 will squeeze the first pressure block 1371, so that the direction-changing roller 135a and the limit ring 1372 will slide downward at the same time, and the limit ring 1372 will press the transmission belt 134 to move downward, thereby causing the driving block 1341a and the baffle 1331 to be misaligned and then out of contact, and then the scanner 131 can slide to the end close to the printer body 11 under the elastic force of the first elastic member to perform the next scanning operation.

[0065] When the scanner 131 completes scanning, the robot will move to grab and deliver the label paper to be pasted. When the robot grabs the label paper to be pasted, the scanner will slide and reset in the direction close to the printer body 11, and then the above process will be cyclically operated.

[0066] This completes the working process of the printer of this embodiment.

[0067] The following is a second embodiment of a printer provided by the present invention that can solve the above technical problems.

[0068] The same structural units as those in the first embodiment are denoted by the same reference numerals in this embodiment. Compared with the first embodiment, the main difference lies in the driving and unlocking of the scanner 131 by the transmission belt 134 .

[0069] Please refer to Figure 7 A printer includes a printer body 11, a label receiving module 12, a robot arm and a scanning module.

[0070] The printer body 11 is used for printing original label paper. The printer body 11 can peel the original label paper from the release paper to form the label paper to be pasted. One side of the printer body 11 is provided with an output port for outputting the label paper to be pasted.

[0071] The label receiving module 12 is docked at one side of the output port, and includes a transport platform. A sensor 127 for sensing the label paper to be pasted is arranged below the transport platform. The transport platform receives the label paper to be pasted and transports it to a set position for the robot to grab. The scanning module is movably arranged above the label receiving module 12 to scan the label paper to be pasted moving on the transport platform. The robot grabs and labels the label paper to be pasted according to the scanning information of the label paper to be pasted by the scanning module.

[0072] In this embodiment, the transport platform includes a main frame 121, a driving roller 122, a driven roller 123, a motor 124 and a belt 125. The driving roller 122 and the driven roller 123 are rotatably arranged on the main frame 121, the motor 124 is transmission-connected to the driving roller 122, and the belt 125 is connected between the driving roller 122 and the driven roller 123.

[0073] The scanning module includes a fixed frame 132, a transmission mechanism, a first elastic member and a scanner 131. The scanner 131 is slidably set on the fixed frame 132, and the scanner 131 scans downward. The transmission mechanism is connected to the active roller 122, and the transmission mechanism includes a driving block 1341b for driving the scanner 131 to slide. The driving block 1341b drives the scanner 131 to move synchronously with the label paper to be attached on the transport platform. During the synchronous movement, the scanner 131 can scan the label paper to be attached. The first elastic member is set between the scanner 131 and the fixed frame 132, and the first elastic member is used to drive the scanner 131 to slide and reset in a direction close to the printer body 11.

[0074] Among them, the transmission mechanism includes a changing roller and a transmission belt 134. The two changing rollers are connected to the fixed frame 132 and are located on one side of the sliding track of the scanner 131. The transmission belt 134 is connected to the active roller 122 and the changing roller. The part of the transmission belt between the two changing rollers is parallel to the sliding track of the scanner 131. The driving block 1341b is connected to the side of the transmission belt 134 close to the scanner 131.

[0075] Please refer to Figure 7 In this embodiment, the fixed frame 132 is slidably connected to the sliding plate 133, the first elastic member is connected between the fixed frame 132 and the sliding plate 133, and the first elastic member can be movably connected to the sliding plate 133, or the description of the first elastic member in the first embodiment can be referred to, the connecting rope of the first elastic member itself can be deformed, so that the first elastic member is movably arranged relative to the sliding plate 133.

[0076] The scanner 131 is elastically and movably connected to the sliding plate 133 through a third elastic member. A first pressing block 21 for pressing the scanner 131 is fixedly provided at one end of the fixing frame 132 away from the printer body 11. The first pressing block 21 is used to press the scanner 131 to move away from the contact with the driving block 1341b. The first pressing block 21 can directly press the scanner 131, or a second pressure block 24 for pressing the first pressing block 21 can be provided on the scanner 131, so that the setting of the scanner 131 can be more flexible.

[0077] In this embodiment, an extension plate 23 for contacting the driving block 1341 b is connected to one side of the scanner 131 , so that the position of the scanner 131 on the sliding plate 133 can be set more flexibly.

[0078] Please refer to Figure 7 and Figure 8 , wherein the driving block 1341b includes a notch 1341b1 for positioning and contacting with two side surfaces adjacent to the scanner 131, and a directional plate 22 is provided on one side of the fixing frame 132, and the directional plate 22 is in sliding contact with the scanner 131. Since the scanner 131 is movably connected to the sliding plate 133, the cooperation between the notch 1341b1 and the directional plate 22 can make the scanner 131 slide more stably. The length of the directional plate 22 is less than the sliding stroke length of the scanner 131. When the first squeezing block 21 squeezes the scanner 131 to move, the directional plate 22 is misaligned with the scanner 131, so that the scanner 131 can slide in a direction away from the transmission belt 134, thereby making the extension plate 23 disengage from the driving block 1341b.

[0079] The working principle of this embodiment is similar to that of the first embodiment, wherein the main difference is that, after the scanner 131 has finished scanning, the first extruding block 21 will squeeze the second pressed block 24, so that the scanner 131 can slide away from the transmission belt 134, thereby making the extension plate 23 disengage from the driving block 1341b, and then under the elastic force of the first elastic member, the scanner 131 can slide to the end close to the printer body 11 to perform the next scanning operation. The rest of the process will not be described in detail here.

[0080] The scanning module of the present invention can scan the label paper to be pasted moving on the transport platform. When the label paper to be pasted moves into position on the label receiving module, the scanning work is completed, and the manipulator can immediately perform the grabbing operation, so the working efficiency is high.

[0081] In summary, although the present invention has been disclosed as above by the above embodiments, the above embodiments are not intended to limit the present invention. Ordinary technicians in this field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
