Specific Embodiments

[0040] The following are specific embodiments of the invention and, in conjunction with the accompanying drawings, further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0041] Embodiment 1

[0042] As Figures 1 - 3 shown, the device for forming a coil and applying ink to a printing ribbon includes a ribbon traction mechanism 1, an uninked ribbon coiling mechanism 2, and an ink application mechanism 3 fixed on a frame 4.

[0043] The ribbon traction mechanism 1 is used to tension and traction an uninked ribbon to the uninked ribbon coiling mechanism 2;

[0044] The uninked ribbon coiling mechanism 2 is used to obtain the tensioned uninked ribbon tractioned by the ribbon traction mechanism 1 and make the two end portions of the uninked ribbon be horizontally butted together. The butt joint is carried out by heating butt joint, and after the heating butt joint, leveling treatment is carried out at the butt joint to make the printing ribbon have a complete and smooth contact surface.

[0045] The ink application mechanism 3 is used to apply ink to the uninked ribbon after it is coiled by the uninked ribbon coiling mechanism 2.

[0046] In this embodiment, mechanical automation is used for processing and printing the ribbon, which not only improves the processing efficiency of the printing ribbon, but also further enhances the processing quality of the printing ribbon, significantly reducing the rejection rate and virtually reducing the production cost. It can be applied to large-scale production and processing, meeting the current development trend of low cost and high efficiency of enterprises.

[0047] Specifically, as Figures 1 - 3 shown, the ribbon traction mechanism 1 of this embodiment includes a ribbon tensioning wheel set 10, a ribbon rear-end clamping device 11, a cutting device 12, and a ribbon front-end traction manipulator 13 that are sequentially arranged in the traction forward direction.

[0048] The uninked ribbon forming loop mechanism 2 moves and clamps both ends of the uninked ribbon that is tensioned between the ribbon rear-end clamping device 11 and the ribbon front-end traction manipulator 13, and the cutting device 12 cuts one end of the uninked ribbon close to the ribbon rear-end clamping device 11.

[0049] The ribbon tensioning wheel set 10 includes a number of upper row wheels and a number of lower row wheels located below the upper row wheels. The uninked ribbon passes between the upper row wheels and the lower row wheels. In this way, combined with the ribbon front-end traction manipulator 13, the uninked ribbon can be tractioned in a tensioned state.

[0050] The ribbon rear-end clamping device 11 includes a lower clamping die. An elevating and pressing die is provided on the lower clamping die. By setting guide columns and guide holes between the lower clamping die and the elevating and pressing die, the elevating and pressing die can smoothly move up and down. A pressing space for pressing the uninked ribbon is formed between the lower clamping die and the elevating and pressing die. The thickness of the pressing space is slightly smaller than the thickness of the ribbon. The formation of the pressing space can be in the following way: ribbon profiling grooves are respectively provided on the lower clamping die and the elevating and pressing die, or ribbon profiling grooves can be provided on one of the dies. That is, the ribbon front-end traction manipulator 13 and the ribbon rear-end clamping device 11 clamp the front and rear ends of the uninked ribbon to facilitate the uninked ribbon forming loop mechanism 2 to obtain the uninked ribbon. When the uninked ribbon forming loop mechanism 2 obtains the uninked ribbon, at this time, the cutting device 12 cuts the uninked ribbon, and the ribbon front-end traction manipulator 13 releases, and the uninked ribbon forming loop mechanism 2 can then complete the loop forming operation. During the loop forming operation, the uninked ribbon forming loop mechanism 2 leaves the traction trajectory of the ribbon front-end traction manipulator 13 so that traction and loop forming can be carried out simultaneously.

[0051] Secondly, after the non-inked ribbon looping mechanism 2 obtains the non-inked ribbon and when the cutting operation of the cutting device 12 is completed, at this time, the front end of the non-inked ribbon is exposed (a section originally clamped by the ribbon front end traction manipulator 13). When the cutting device 12 cuts the rear end of the non-inked ribbon, a reserved section of the same length as the front end of the non-inked ribbon is reserved. Of course, the lengths can also be different. That is, the non-inked ribbon looping mechanism 2 obtains the non-inked ribbon, and both the front end and the rear end of the non-inked ribbon have reserved lengths, so that the reserved length sections can contact and be placed flat at the heat-sealing station.

[0052] The cutting device 12 includes scissors and a driving cylinder that drives the two handles of the scissors to move towards each other or away from each other. Since the ribbon rear end clamping device 11 and the ribbon tensioning wheel set 10 keep the non-inked ribbon taut, at this time, the cutting device 12 can smoothly perform the cutting operation.

[0053] Specifically, as Figures 1 - 3 shown, the non-inked ribbon looping mechanism 2 of this embodiment includes a translation driving device 20. The translation driving device 20 includes a moving plate that is slidably matched with the frame 4. A linear drive is provided between the moving plate and the frame 4. The linear drive is, for example, a combination of a lead screw and a motor, or can also be a drive such as a cylinder or an oil cylinder. And a guiding method of combining a guiding rod and a guiding sleeve is adopted between the moving plate and the frame 4. Of course, a guiding method of a guide rail pair can also be adopted.

[0054] Two symmetrically distributed rotary manipulators 21 are provided on the translation driving device 20. The rotary manipulator 21 includes a rotary oil cylinder or a cylinder. A finger cylinder is connected to the rotary oil cylinder or the cylinder, and two clamping claws are connected to the finger cylinder. The two clamping claws move towards each other and away from each other under the drive of the finger cylinder to clamp and unclamp the non-inked ribbon.

[0055] As Figures 1 - 3 shown, a heat-sealing and leveling module 22 is provided on the frame 4 between the two rotary manipulators 21; the heat-sealing and leveling module 22 has the functions of heat pressing and leveling. Specifically, the heat-sealing and leveling module 22 includes a lower die and an upper die. The upper die is connected to a lifting drive. The lifting drive includes any one of a cylinder and an oil cylinder. That is, the heat-sealing and leveling module 22 has a heat-sealing station and a leveling station; in order to minimize the influence of the heat-sealing temperature on the ink application quality of the ribbon, the width of the heat-sealing station in this embodiment is smaller than the width of the leveling station. Specifically: a narrow edge part is provided in the middle of the lower die, and thick edge parts are respectively provided at both ends of the narrow edge part. The narrow edge part and the thick edge parts form a dumbbell-shaped structure. The narrow edge part is the heat-sealing station, and one of the thick edge parts is the leveling station. The upper die is of equal thickness or is in imitation of the above-mentioned lower die structure.

[0056] A heater is provided on the upper die and / or the lower die. The heater is in the form of an electric heating rod or heating wire, etc. Of course, ultrasonic welding can also be used and can be embedded in the upper die and / or the lower die to improve the use safety. After the upper die and / or the lower die are heated, the heat is conducted to the butt joint of the ribbon on the upper die, and then the butt joint is heat-bonded together by the cooperation of the upper die and the lower die.

[0057] The translation driving device 20 drives the two rotary manipulators 21 to alternately translate between the heat-bonding station and the leveling station, and the driving direction of the translation driving device 20 and the traction direction of the ribbon traction mechanism 1 are vertically distributed, that is, the translation driving is performed laterally in the traction direction; generally, heat connection is performed first, and then leveling. No matter which station, the two rotary manipulators 21 always clamp the ribbon at this time.

[0058] The two rotary manipulators 21 rotate upward in opposite directions so that the two ends of the uninked ribbon are aligned and contacted and placed flat on the heat-bonding station. The two rotary manipulators 21 can rotate synchronously or asynchronously, as long as it can ensure that the two ends of the uninked ribbon are aligned and contacted and placed flat on the heat-bonding station.

[0059] In a preferred embodiment, the two rotary manipulators 21 are horizontally distributed and rotate upward 180° in opposite directions. That is, rotate outward from bottom to top, and the reset can be performed according to the original trajectory. The rotary manipulator 21 is below when the rotary manipulator 21 rotates in place to obtain the uninked ribbon.

[0060] Such as Figure 1 、 Figure 5 and Figure 6 As shown, a transfer manipulator 5 is provided on the frame 4 for obtaining the uninked ribbon formed by the uninked ribbon forming mechanism 2 and transferring it to the inking mechanism 3. After heat-bonding and leveling, the transfer manipulator 5 obtains the coiled uninked ribbon at the heat-bonding position at this time, the rotary manipulator 21 releases, and the transfer manipulator 5 transfers and slews the coiled uninked ribbon onto the inking mechanism 3.

[0061] The transfer manipulator 5 is a multi-dimensional moving manipulator, and the dimensions include a horizontal X-axis and a horizontal Y-axis perpendicular to the vertical direction (such as the Z-axis). The horizontal X-axis is distributed along the traction direction, and the horizontal Y-axis is the horizontal direction perpendicular to the horizontal X-axis. For example, when obtaining the coiled uninked ribbon, the transfer manipulator 5 first moves in the horizontal Y-axis to obtain it, then resets and moves in the horizontal X-axis. When moving to the inking mechanism 3, the transfer manipulator 5 then moves in the horizontal Y-axis to release the coiled uninked ribbon.

[0062] The horizontal X-axis and the horizontal Y-axis in this embodiment adopt the drive mode of a screw combination motor. Of course, it can also be in the form of a cylinder or an oil cylinder. The mechanical claw structure of the transfer manipulator 5 is a finger cylinder, and two jaw bodies are connected to the finger cylinder to realize the clamping and unclamping of the ribbon.

[0063] Specifically, as Figure 1 , Figure 5 and Figure 6 shown, the inking mechanism 3 of this embodiment includes an inking rotating group 30 with belt tensioning, and a stripping device 31 for driving the looped inking ribbon around the inking rotating group 30 with belt tensioning to separate from the inking rotating group 30 with belt tensioning. Further, the inking rotating group 30 with belt tensioning includes an upper rotating shaft 300 and a tensioning shaft 303 located below the upper rotating shaft 300. One end of the upper rotating shaft 300 is connected to a rotating drive 301. The rotating drive 301 is a motor, such as a servo motor, which is fixed on the frame 4. Of course, the rotating drive 301 can be connected to one end of the upper rotating shaft 300 through a belt drive, and of course, it can also be directly connected. The other end of the upper rotating shaft 300 is distributed in a suspended manner, and an inking cotton 302 is sleeved on the suspended end of the upper rotating shaft 300. The inking cotton 302 is cylindrical and is pre-immersed in the printing ink so that the inking cotton 302 carries the printing ink.

[0064] One end of the tensioning shaft 303 is connected to a lifting drive 304. The lifting drive 304 is a cylinder or an oil cylinder, and the other end of the tensioning shaft 303 is distributed in a suspended manner.

[0065] Preferably, the suspension direction of the suspended end of the upper rotating shaft 300 in this embodiment is the same as the suspension direction of the suspended end of the tensioning shaft 303, and the two are in a relationship of being parallel to each other or at a certain acute angle, so that the uninked ribbon can be wound around the inking cotton 302 and the tensioning shaft 303.

[0066] The tensioning shaft 303 is driven by the lifting drive 304 to move relatively closer to the upper rotating shaft 300. At this time, the distance between the upper rotating shaft 300 and the tensioning shaft 303 is reduced to facilitate the sleeving of the uninked ribbon. When the uninked ribbon is sleeved in place, the lifting drive 304 then drives the tensioning shaft 303 to move downward to realize the tensioning of the uninked ribbon. In the tensioned state, the inking cotton 302 will apply the printing ink to the uninked ribbon due to the force, and the tensioned uninked ribbon will rotate under the drive of the upper rotating shaft 300. To reduce friction, the tensioning shaft 303 is a smooth optical axis.

[0067] As Figures 5 - 7As shown in the figure, the stripping device 31 includes a stripping moving rod 310 horizontally disposed between the upper rotating shaft 300 and the tensioning shaft 303. The stripping moving rod 310 is connected to a stripping moving driver 311. The stripping moving driver 311 is a cylinder or an oil cylinder. The stripping moving rod 310 drives the inking ribbon in a loop to disengage from the inking cotton 302 and the tensioning shaft 303. In a preferred embodiment, a plastic tube is sleeved on the stripping moving rod 310. The plastic tube has a suspended section. That is, a part of the axial length of the plastic tube is sleeved on the stripping moving rod 310, and the remaining part is not sleeved on the stripping moving rod 310. By using the plastic tube to contact the inking ribbon in a loop and making the inking ribbon in a loop be stripped, it can prevent the inking ribbon in a loop from being bruised, damaged or deformed.

[0068] To facilitate stripping, the tensioning shaft 303 of this embodiment is inclined upward. That is, it is inclined and distributed at an angle less than 10°, for example, at an angle of 3° or 2°. Since the inking cotton 302 itself has a certain elastic tension, and the inclination of the tensioning shaft 303 can make the stripping of the inking ribbon in a loop by the stripping moving rod 310 simpler. Of course, the tensioning shaft 303 can also be parallel to the upper rotating shaft 300.

[0069] In this embodiment, the cylinder is preferably a double-rod cylinder.

[0070] As Figure 4 shown, the continuous uninked ribbon can be divided into a ribbon front-end traction and clamping section a1, a rotating manipulator clamping section a2, a cutting area a3, a ribbon rear-end clamping section a4, and a tensioning wheel group section a5 from the front end to the rear end.

[0071] Embodiment 2

[0072] As Figures 1 - 7 shown, a method for inking a printing ribbon in a loop using the device for inking a printing ribbon in a loop in Embodiment 1 includes the following steps:

[0073] S1. The ribbon traction mechanism 1 traction the uninked ribbon in a taut and straight state to the uninked ribbon looping mechanism 2.

[0074] S2. The uninked ribbon looping mechanism 2 obtains the uninked ribbon tractioned in S1 and makes the two end portions of the uninked ribbon be horizontally butted together to obtain a looped uninked ribbon.

[0076] Then, repeat the above steps S1 - S3 to process the next printing ribbon.
