Description

Technical Field

[0001] The invention relates to the field of ink cartridge filling, and in particular to an automatic ink cartridge filling production line and method. Background Art

[0002] Ink cartridges are special consumables for digital integrated quick printing machines. Due to the advantages of digital integrated quick printing machines in printing, such as economy, environmental protection, fast printing speed, and good clarity, the usage of digital integrated quick printing machines has been increasing in recent years, especially in schools, enterprises, and institutions with large printing volumes. Therefore, the usage of ink cartridges, one of the consumables used by digital integrated quick printing machines, has also been increasing. The structure of the ink cartridge 100 for digital integrated quick printing machines is shown in FIG. Figure 1 As shown, it is composed of an ink barrel 101, a nozzle 102, an ink cover 103, a piston 104, a bottom cover 105, etc. The main part is a cylindrical ink barrel with a wall thickness of about 2 mm and a diameter of about 80 mm; the upper end of the barrel is an ink nozzle 106. After the ink is filled, a nozzle needs to be installed in the ink nozzle. The nozzle is the ink injection interface connected to the machine when the ink barrel is installed on the digital integrated quick printing machine. The ink barrel that is normally filled with ink needs to be covered with an ink cover to prevent the ink from overflowing. The ink cover is unscrewed when it needs to be installed on the digital integrated quick printing machine. There is a piston in the ink barrel. When the digital integrated quick printing machine is printing, the piston in the ink barrel is pushed by the machine's top rod to inject the ink into the printing roller of the machine for printing. The bottom of the ink barrel is a bottom cover with a hole to prevent the piston from falling out of the barrel.

[0003] At present, the ink filling machines for ink cartridges in China are generally single-machine filling machines that adopt the inverted filling process. They can only fill one ink cartridge at a time, and the exhaust air before filling the ink cartridge, the installation of the nozzle after filling, the ink cover and other processes can only be completed by manual operation, which has low production efficiency and high labor intensity for workers, especially the installation of the nozzle and the cover of the ink, which often cause blisters on the workers' hands. The advantage of the inverted filling process is that the structure is simple. When filling, the ink nozzle of the ink cartridge that has been manually exhausted is buckled downward on the filling nozzle of the filling machine. When the filling machine injects ink into the ink cartridge body, the ink pushes the piston to move up slowly until it is full; the disadvantage of the inverted filling process is that it cannot be used for automated filling production lines, mainly because the ink nozzle is downward, and the ink cartridge is easy to cause ink to pour out after leaving the filling nozzle of the filling machine. The subsequent processes such as installing the nozzle and covering the ink cover are difficult to realize automation, so other processes can only be operated manually, making it difficult to improve production efficiency.

[0046] like Figure 2 and 7 As shown, the capping mechanism 6 is arranged at the capping station F, and is used to tighten the ink cap 103 on the ink nozzle. Specifically, the capping mechanism 6 may include a capping bracket 61, at least one capping lifting cylinder 62 (two are shown), a capping beam 63, a plurality of capping motors 64 (five are shown), and a plurality of capping pressing plates 65 (five are shown).

[0047] like Figure 2 and 8As shown, the discharging mechanism 7 is arranged on the discharging station G, and is used to take out the ink cartridge 100 with the cap screwed on from the ink cartridge conveyor belt 1. Specifically, the discharging mechanism 7 includes a clamping plate frame 71, a clamping plate frame lifting cylinder 72, a clamping plate beam 73, a clamping plate beam slide rail 74, a clamping plate beam moving cylinder 75, a plurality of clamping plates 76 and a plurality of clamping plate cylinders 77.

Therefore, the ink cartridge 100 with the cap screwed on can be moved from the ink cartridge conveying belt 1 to the coding conveying belt 81 of the coding mechanism 8 through the discharging mechanism 7 .

[0048] like Figure 1 As shown, the coding mechanism 8 includes a coding conveyor belt 81 and a coding nozzle 82. The coding conveyor belt 81 is arranged horizontally at the discharge station, forming an L shape with the ink cartridge conveyor belt 1, and is provided with a coding station H and a boxing station I. The boxing station I is located at the end of the coding conveyor belt 81. Workers can pack ink cartridges into boxes 9 at the boxing station I. The coding nozzle is installed at the coding station H, and is used to code the ink cartridges, such as barcodes, production dates, etc. It should be understood that the coding mechanism 8 can also be arranged at the end of the ink cartridge conveyor belt 1, that is, in a straight line with the ink cartridge conveyor belt 1. In some embodiments, the ink cartridge automatic filling production line may also not be arranged with the coding mechanism 8.

[0049] The following is a brief description of the working process of the automatic ink cartridge filling production line of the present invention. After the worker places the empty ink cartridge upright on the ink cartridge fixing fixture at the ink cartridge delivery station A, the ink cartridge conveyor belt 1 conveys it to the exhaust and filling station B. At this station, the exhaust cylinder 22 acts, and the exhaust push rod 21 pushes the piston 104 of the ink cartridge to move upward to discharge the air in the ink cartridge. Then the filling nozzle 23 of the filling mechanism 2 descends and inserts into the ink nozzle of the ink cartridge, and injects the set amount of ink. The pressure of the injected ink and the gravity of the ink push the piston downward, and the bottom of the piston is acted on by the upward thrust of the exhaust push rod so that it will not hang down quickly, thus avoiding the phenomenon of rapid hanging and generating bubbles. After the ink is filled, the filling nozzle 23 is lifted, and then the ink cartridge conveyor belt 1 conveys the ink cartridge to the nozzle delivery station C. The nozzle delivery mechanism 3 automatically and orderly conveys the nozzle 102 to the nozzle delivery station in the correct direction and puts it on the ink nozzle of the filled ink cartridge. Then the ink cartridge conveyor belt delivers it to the nozzle installation station D, where the nozzle is pressed into the ink nozzle of the ink cartridge under the action of the cylinder 42 and the pressure plate 43. Then the ink cartridge conveyor belt delivers the ink cartridge to the capping station E, where the capping mechanism 5 first arranges the ink caps in the correct direction and places the ink caps on the ink nozzles of the ink cartridges at the capping station. Then the ink cartridge conveyor belt delivers the ink cartridge to the capping station F, where the capping lifting cylinder 62 pushes the capping pressure plate 65 to press the ink cap 103 and the capping motor 64 tightens the ink cap on the ink nozzle of the ink cartridge. Then the ink cartridge conveyor belt delivers it to the discharging station G, where the discharging mechanism 7 simultaneously clamps the ink cartridge 100 out of the ink cartridge fixing fixture 11 and places it on the coding conveyor belt 81. The coding conveyor belt 81 carries the ink cartridge through the coding nozzle 82 and is sent to the boxing station I after coding, where the worker removes the ink cartridge and packs it into the box 9. It should be understood that the ink cartridge delivery and boxing steps can also be automatically completed using corresponding robots.

[0050] The ink cartridge filling production line of the present application can fill several ink cartridges at the same time and adopts a fully automated assembly line process, so the filling efficiency is greatly improved. With the same number of workers, the filling efficiency can be increased by several times. Moreover, the filling production line is easy to operate and is fully controlled by an automatic control program. Workers only need to place the empty ink cartridge upright in the ink cartridge fixing position and pack the filled ink cartridges at the box entry, which greatly reduces the labor intensity.

[0051] like Figure 1-8 According to another aspect of the present invention, there is also provided an automatic ink cartridge filling production method, which may include the following steps:

[0052] An ink cartridge conveyor belt 1 is provided, on which an ink cartridge fixing fixture 11 is installed, each ink cartridge fixing fixture can place a row of ink cartridges 100 upright, and the ink cartridge conveyor belt is sequentially arranged with an ink cartridge placing station A, an exhaust and filling station B, a nozzle placing station C, a nozzle installation station D, a capping station E, a capping station F and a discharging station G along the conveying direction;

[0053] At the ink cartridge placing station A, an empty ink cartridge is automatically or manually placed upright on the ink cartridge fixing fixture 11 of the ink cartridge conveyor belt 1;

[0054] At the exhaust and filling station B, the air in the ink cartridge is automatically exhausted by the exhaust and filling mechanism 2, and the ink is filled into the exhausted ink cartridge;

[0055] At the nozzle placement station C, the nozzle is automatically placed onto the ink nozzle of the filled ink cartridge by the nozzle placement mechanism 3;

[0056] At the nozzle installation station D, the nozzle is automatically pressed into the ink nozzle of the ink cartridge by the nozzle installation mechanism 4;

[0057] At the capping station E, the ink cap is automatically placed on the ink nozzle of the ink cartridge by the capping mechanism 5;

[0058] At the capping station F, the ink cap on the ink nozzle is automatically tightened by the capping mechanism 6;

[0059] At the discharging station G, the ink cartridge with the cap screwed on is automatically taken out from the ink cartridge conveyor belt by the discharging mechanism 7 .

[0060] The structures and functions of the exhaust and filling mechanism 2, the nozzle delivery mechanism 3, the nozzle installation mechanism 4, the capping mechanism 5, the capping mechanism 6 and the discharging mechanism 7 have been described above and will not be repeated here.

[0061] In this embodiment, the method also includes coding and packing steps. Specifically, a coding mechanism 8 is provided, which includes a coding conveyor belt 81 and a coding nozzle 82. The coding conveyor belt 81 is arranged horizontally at the discharge station and forms an L shape with the ink cartridge conveyor belt. A coding station H and a packing station I are provided.
