Description

Technical Field

[0001] The utility model relates to the technical field of a device for paging and coding cartons, and in particular to an automatic paging and coding machine device for cartons which links automatic paging of cartons with automatic coding of production date and shelf life. Background Art

[0002] At present, in the production of cartons mainly for food packaging, the production date needs to be printed on the side of the carton after the carton is folded into a flat shape. Printing the production date of the carton is very important. Initially, the production date of the carton was manually stamped with a seal. When manually stamping, it is necessary to manually pick up and put the cartons one by one. Since the cartons have a certain weight and volume, this manual stamping method is not only labor-intensive, inefficient, but also often blurred. Later, after technical improvements, a printer was used to print the production date on the carton. However, since the date of the carton now needs to be printed on the right-angled sides after the carton is formed (that is, the two sides of the carton side in an L-shaped state), if the existing inkjet method is used, the folded carton needs to be made into a box body first, and then two inkjet printers are used for printing on both sides, and a turning mechanism needs to be installed for the turning of the carton to achieve printing on both sides, which will increase the production cost and require a large space for production equipment. Finally, after the cartons are produced, they are stacked together in groups of ten or dozens. When printing, they are laid flat and stacked together, and then they need to be taken down one by one and put into the coding process manually, which also causes high labor intensity for workers. Currently, there are paging machines on the market that can realize the paging separation of stacked materials and convey them to the production line in sequence, but the paging machines on the market are all set up for upper and lower paging, which makes it easy to push the upper and lower stacked cartons together into the production line during paging, causing the lower carton to fail to print or the two cartons to get stuck on the production line and fail to print. Therefore, in order to reduce labor intensity, improve the efficiency and information of production date printing, improve the paging level and reduce printing failures, it is necessary to work together with the paging device and the inkjet printer to form an overall coherent production line.

[0003] However, in the prior art, there is no technical solution or Chinese patent document that links automatic coding and paging together, and further improvement or modification is needed. Summary of the invention

[0004] The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a carton automatic paging inkjet printer device, which has the functions of automatic paging of cartons and inkjet production date, and links the automatic paging of cartons with the automatic inkjet production date and shelf life, so as to achieve the purpose of improving work efficiency, and the inkjet printing of both sides can be completed without making the flat cartons into a box state; and when paging the cartons, the cartons are changed from a flat stacking paging mode to an upright stacking mode, and the cartons are transported in an upright state during paging and conveying, and double nozzles are set to complete the inkjet printing of both sides of the carton (the two sides of the flat carton are in the same direction). The coordinated use of the automatic paging of the carton and the inkjet printing on both sides forms a coherent production line, which not only greatly improves the efficiency of printing the date on the carton, but also reduces the labor intensity. It originally required 2 people to complete the printing date operation, but only 1 person is needed to meet the requirements; and the paging and inkjet printing are stable, the date printing quality is greatly improved, and the printing quality of the carton is improved.

[0021] Example 1

[0022] The carton automatic paging inkjet printer device described in this embodiment 1 is as follows: Figure 1 As shown in the figure, it includes an automatic paging device 1 for paging vertically stacked cartons, and a coding device 2 arranged at the carton output end of the automatic paging device. The technical solution of this embodiment 1 is composed of two major components spliced ​​and linked, namely, an automatic paging device that realizes the vertically stacked conveying of cartons and the sequential paging and separation of each carton during conveying, and a coding device that realizes the production date and shelf life date coding printing on both sides of two flat cartons connected on the same plane of the vertically conveyed cartons, so as to achieve the linkage production of automatic paging and separation of carton conveying and automatic coding printing on both sides of the carton, forming a continuous and uninterrupted automated production mode, improving production efficiency and reducing the generation of defective products.

[0023] The automatic paging device includes a carton paging operation platform 3, a paper pressing cylinder 4 installed at the bottom of the carton paging operation platform, a paper pressing push rod 5 connected to the output end of the paper pressing cylinder, a paper pressing board assembly 6 fixedly installed with the paper pressing push rod and located on the carton paging operation platform, a paging belt assembly 7 installed at the rear end of the carton paging operation platform and facing the paper pressing board assembly for driving and conveying cartons, and a paging separation limit assembly 8 installed on the side of the carton paging operation platform and corresponding to the carton output end of the paging belt assembly. The side of the paging operation platform is provided with a pressure plate button (not shown in the figure) for controlling the action of the paper pressing cylinder and a start button (not shown in the figure) for controlling the action of the paging belt assembly. When the cartons are paging, dozens of stacked flat cartons are placed upright on the carton paging operation platform and pressed against the paging belt assembly. The pressure plate button is pressed, the paper pressing cylinder starts and drives the paper pressing push rod and the paper pressing board assembly to press the carton against the paging belt assembly. Then the start button is pressed, the paging belt assembly starts and outputs a carton in contact with it through the belt conveyor, while the other cartons will be blocked by the paging separation limit assembly and will not be brought out together, thus forming the effect of paging, separation and output of the cartons. In this way, after the current carton is brought out for transportation, the paper pressing board assembly continues to squeeze the stacked cartons, and continues to realize that the next carton is paging, separated and output by the paging belt assembly to the inkjet device.

[0024] The coding device includes a carton conveyor frame 9, a carton conveyor belt 10 installed flat on the carton conveyor frame and used to convey cartons, a coding assembly 11 installed at the rear end of the carton conveyor frame, and a carton bottom positioning seat 12 installed on the carton conveyor frame above the carton conveyor belt and not in contact with the carton conveyor belt, a carton middle supporting cross bar 13 located on the same side above the carton bottom positioning seat and used to position and support the middle position of the carton, and a carton upper supporting cross bar 14 located above the carton middle supporting cross bar and on a different side for positioning and supporting the upper position of the carton. When the flat cartons are paged and separated and conveyed in, first the bottom of the carton is pressed against the carton conveyor belt and conveyed to the coding location, and a slightly higher position of the bottom of the carton enters the bottom positioning seat of the carton to form the bottom positioning conveying during conveying, while the middle part of the carton is supported by the middle supporting cross bar of the carton to form the middle positioning conveying and the upper part of the carton is supported by the upper supporting cross bar of the carton to form the upper positioning, so that the carton can be conveyed in an upright state, and then the coding is printed through the coding assembly.

[0025] In the present embodiment 1, the paper pressing assembly comprises a paper pressing seat 15 fixedly connected to the paper pressing push rod, a paper pressing vertical bar 16 standing on the paper pressing seat, a paper pressing diagonal bar 17 connected and installed with the paper pressing vertical plate, and a paper pressing 18 connected and installed with the paper pressing diagonal bar and facing the paging belt assembly. The paper pressing seat serves as the base of the paper pressing, and the paper pressing vertical bar, the paper pressing diagonal bar and the paper pressing all protrude from the carton paging operation platform, wherein the paper pressing vertical bar extends from the top of the carton paging operation platform, the paper pressing is vertically arranged and faces the middle of the vertical surface of the carton, and the area of ​​the paper pressing is about 1 / 4-1 / 3 of the vertical surface of the carton, and can steadily press the carton on the paging belt assembly.

[0026] In the present embodiment 1, the paging belt assembly comprises an active rotating shaft 19 and a passive rotating shaft 20 arranged vertically, a paging belt 37 arranged between the active rotating shaft and the passive rotating shaft, and a paging belt motor (not shown in the figure) connected to the active rotating shaft and driving the active rotating shaft to rotate; the paging belts are provided with two, respectively located between the upper part of the active rotating shaft and the upper part of the passive rotating shaft and between the lower part of the active rotating shaft and the lower part of the passive rotating shaft. When the paging belt assembly is started, the active rotating shaft is driven to rotate by the paging belt motor, and the active rotating shaft drives the passive rotating shaft to rotate through the paging belt. At this time, the upper and lower paging belts provided will drive the upper and lower parts of the carton to be transported to the inkjet device.

[0027] In the present embodiment 1, the paging separation limiter assembly comprises a paging vertical rod 21, a paging movable seat 38 that is movably mounted on the paging vertical rod and can be lifted and lowered to adjust the height, a paging locking knob 22 that locks the height position of the paging movable seat, and a paging limiter plate 23 that is installed on the paging movable seat and faces the output direction of the side of the carton; the paging limiter block is in an inverted L shape. When the carton is brought out by the paging belt, the back of the inverted L-shaped paging limiter block will pass through the output, and at this time, the left side of the paging limiter plate will block the carton behind so that these cartons will not be brought out at the same time, thus achieving the effect of paging separation with only one carton brought out; the distance between the back of the paging limiter block and the horizontal direction of the paging belt is greater than the thickness of one carton and less than 1.5 carton thicknesses, so that the carton can be smoothly output and block other cartons. In addition, since different cartons have different heights, when cartons of different heights need to be paginated and printed, the height of the pagination movable seat and the pagination limit plate can be adjusted through the pagination locking knob to adapt to the pagination and printing production of cartons of different heights, with good flexibility and the ability to expand the scope of use.

[0028] In the present embodiment 1, the inkjet coding assembly includes an upright inkjet coding pole 24, an inkjet coding seat 25 that is movably mounted on the inkjet coding pole and can be raised and lowered to adjust the height, an inkjet coding locking knob 26 that locks the height position of the inkjet coding seat, a double nozzle 27 that is mounted on the locking inkjet coding seat and faces the carton, an ink tank 28 that is mounted on the side of the inkjet coding seat and connected to the double nozzle, and also includes an inkjet coding display screen (not shown in the figure) that is mounted on the carton conveyor frame and connected to both the double nozzle and the ink tank. When the carton passes by, the production date and the shelf life date are printed on the two sides of the carton in turn by the double nozzles that are set one after the other and at different heights, that is, the printing of the two sides can be completed after the carton is conveyed once, and the time difference of the inkjet coding printing on both sides is very small; the ink tank can provide corresponding ink to the double nozzles for inkjet coding printing. Through the inkjet coding display screen, the display of the relevant situation of inkjet coding printing and the working status can be realized. When it is necessary to adjust the inkjet printing position of cartons of different heights, the height of the inkjet movable seat and the dual nozzles can be adjusted through the inkjet locking knob to achieve height adjustment, which is suitable for inkjet printing of cartons of different heights.

[0029] In the present embodiment 1, the carton bottom positioning seat comprises a positioning seat support frame 29, a front positioning cross bar 30 and a rear positioning cross bar 31 which are movably mounted on the positioning seat support frame and are arranged front and back, and a positioning cross bar locking knob 32 for adjusting and locking the distance between the front positioning cross bar and the rear positioning cross bar; the paper feeding end of the front positioning cross bar and the paper feeding end of the rear positioning cross bar are both tilted and expanded outward, and a trumpet shape which gradually narrows from the outside to the inside is formed between the paper feeding end of the front positioning cross bar and the paper feeding end of the rear positioning cross bar. A limit rail guide for limiting the sliding of the carton conveying is formed between the front positioning cross bar and the rear positioning cross bar, and the width of the limit rail guide can be adjusted by adjusting the distance between the front positioning cross bar and the rear positioning cross bar, so as to realize the limit sliding of cartons of different thicknesses. In addition, the paper feeding end of the front positioning cross bar and the rear positioning cross bar forms a trumpet shape, which can make the carton enter without hindrance and smoothly enter the limit rail to slide.

[0030] In this embodiment 1, the carton middle support cross bar is connected to the middle support frame 33, and the middle cross bar locking knob 34 is installed on the middle support frame for adjusting and locking the front and rear positions of the carton middle support cross bar; the carton middle support cross bar is located directly above the front positioning cross bar, and the paper feeding end of the carton middle support cross bar is set to be consistent with the paper feeding end of the front positioning cross bar. After adjusting the width of the limit rail that limits the bottom of the carton, it is also necessary to adjust the front and rear positions of the middle support cross bar to achieve that the middle support cross bar and the front positioning cross bar are on the same vertical plane and keep consistent.

[0031] In this embodiment 1, the carton upper support cross bar is connected to the upper support frame 39, and the upper cross bar locking knob (not shown in the figure) installed on the upper support frame for adjusting and locking the front and rear positions of the carton upper support cross bar; the carton upper support cross bar is located directly above the rear positioning cross bar, and the paper feeding end of the carton upper support cross bar is set consistent with the paper feeding end of the rear positioning cross bar. Just like the adjustment principle of the middle support cross bar mentioned above, after adjusting the width of the limit guide rail that limits the bottom of the carton, it is also necessary to adjust the front and rear positions of the upper support cross bar to achieve that the upper support cross bar and the rear positioning cross bar are on the same vertical plane and remain consistent.

[0032] In this embodiment 1, the carton paging operation platform is provided with a long strip opening 36 that allows the vertical bar of the cardboard pressing paper to pass through from bottom to top and move forward and backward. The long strip opening provided can enable the vertical bar of the cardboard pressing paper to pass through and slide smoothly in the long strip opening.

[0033] In the present embodiment 1, the paging belt assembly and the inkjet movable seat are respectively provided with a paging induction electric eye (not shown in the figure) and an inkjet induction electric eye (not shown in the figure). The paging induction electric eye can sense whether the carton is separated by the paging belt conveyor and enters the inkjet program. At the same time, the paper pressing cylinder can be controlled to drive the paper pressing board to further press the carton, so that the next carton is pressed on the paging belt for paging separation and output. In this way, each carton can be paging, separated and output continuously. The inkjet induction electric eye senses the carton entering the inkjet area and triggers the dual nozzles to perform corresponding inkjet printing on the entering carton.

[0034] When the cartons are paged and printed, the cartons are placed vertically on the carton paging operation platform. A maximum of 200 cartons can be placed at a time. The pressure plate button is pressed to press the carton with the pressure paper, and then the start button is pressed. The paging belt drives the front carton to be separated through the paging separation limit assembly. At this time, the carton is conveyed by the carton conveyor belt, and the bottom of the carton is positioned by the carton bottom positioning seat to prevent the carton from shifting. The middle part of the carton supports the horizontal bar positioning support to block the middle part of the carton, and the upper part of the carton supports the horizontal bar positioning support to block the upper part of the carton, so that the carton is conveyed by the carton conveyor belt. The vertical conveying mode in which the upper, middle and lower parts are supported and positioned is realized, so as to achieve the purpose of stable conveying. Finally, when passing through the front and rear double nozzles of the coding assembly, the two sides of the carton are sprayed with corresponding codes, and the production date and shelf life date can be sprayed to the corresponding positions.

[0035] In this embodiment 1, the carton automatic paging inkjet printer equipment has the functions of automatic paging of cartons and inkjet production date, which links the automatic paging of cartons with the automatic inkjet production date and shelf life, so as to achieve the purpose of improving work efficiency, and the inkjet printing of both sides can be completed without making the flat cartons into a box state; and when paging the cartons, the cartons are changed from a flat stacking paging mode to a vertical stacking mode, and the cartons are transported in an upright state during paging and transportation, and the double nozzles can complete the inkjet printing of both sides of the carton (the two sides of the flat carton are in the same direction). The automatic paging of cartons and the two-sided inkjet printing form a coherent production line, which not only greatly improves the efficiency of printing the date on the carton, but also reduces the labor intensity. It originally required 2 people to complete the printing date operation, but only 1 person is needed to meet the requirements; and the paging and inkjet printing are stable, the date printing quality is greatly improved, and the printing quality of the carton is improved.

[0036] The above is only a preferred embodiment of the utility model, and does not limit the structure of the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model still falls within the scope of the technical solution of the utility model.
