Description

Technical Field

[0001] The present disclosure relates to the technical field of printing equipment, and in particular to a folding vertical carton printing equipment and a carton printing machine. Background Art

[0002] A printer is a device that uses software to control and mark products (marking refers to various barcodes, text, graphics and other information). There are usually two ways of printing: contact and non-contact. Among them, the non-contact method includes continuous inkjet technology (Continuous Inkjet Printer) referred to as CIJ, piezoelectric inkjet printing technology (Piezoelectric Inkjet Printer) referred to as PIJ, and thermal inkjet printing technology (Thermal Inkjet Printer) referred to as TIJ.

[0003] In the current carton packaging field, in order to print product information such as the production order number, production location, and carton weight on the outer surface of the carton, the traditional method is to print when the carton is not folded into shape, that is, in a flat state. This requires manual flipping at least once to print on multiple sides. After printing, it needs to be folded again for packaging. Similarly, for a folded vertical carton, only the top can be printed, and it needs to be manually flipped at least once before printing on other sides. Moreover, during the flipping process, there is a situation where the flipping is not in place, and the flipping angle needs to be adjusted again, resulting in low printing efficiency.

[0026] The present disclosure relates to a folding vertical carton printing device. In one embodiment, the folding vertical carton printing device includes a carton printing machine case, a carton turning mechanism, and a carton inking printing device. The carton printing machine case is used to set a top box conveyor belt and a carton unloading conveyor belt for transmitting folding vertical cartons.

[0027] See also Figure 1 , which is a structural schematic diagram of a folding vertical carton printing device according to an embodiment of the present disclosure.

[0028] The folding vertical carton printing device 10 of one embodiment includes a carton printing machine box 100, a carton turning mechanism 200 and a carton inking printing device 300. The carton printing machine box 100 is used to set a carton loading conveyor belt and a carton unloading conveyor belt for conveying folding vertical cartons. Figure 2 The folding vertical carton turning mechanism 200 includes a transfer conveyor belt 210 and a carton clamping and turning assembly 220. The transfer conveyor belt 210 is located between the upper box conveyor belt and the unloading box conveyor belt. The transfer conveyor belt 210 is used to transfer the folding vertical carton. The carton clamping and turning assembly 220 is arranged on the carton printing machine box 100. The carton clamping and turning assembly 220 is arranged corresponding to the transfer conveyor belt 210. The clamping and turning end of the carton clamping and turning assembly 220 is used to connect with the folding vertical carton and the transfer conveyor belt 210 respectively, so that the folding vertical carton and the transfer conveyor belt 210 are turned together. The carton inking printing device 300 is arranged on the carton printing machine box 100. The carton inking printing device 300 is used to perform coding and inking operations on at least two surfaces of the folding vertical carton.

[0029] In this embodiment, after the folding vertical carton is on the transfer conveyor belt 210, the carton clamping and turning assembly 220 corresponds to the transfer conveyor belt 210, so that the carton clamping and turning assembly 220 can clamp and fix the transfer conveyor belt 210 and the folding vertical carton together. When the carton inking printing device 300 performs multi-sided printing on the folding vertical carton, the carton clamping and turning assembly 220 can turn over the transfer conveyor belt 210 and the folding vertical carton synchronously, so that the surface of the folding vertical carton is flat and not warped, so that the carton inking printing device 300 can print codes with various information on multiple surfaces of the folding vertical carton without manual turning, which effectively improves the multi-sided printing efficiency of the folding vertical carton.

[0030] In one embodiment, the carton inking printing device can adopt contact or non-contact printing. For example, the carton inking printing device is a silk screen printing device; in another example, the carton inking printing device is a spray printing device.

[0031] In one embodiment, see Figure 2The carton clamping and turning assembly 220 includes two oppositely arranged turning clamping and fixing members 222, the turning clamping and fixing members 222 include a turning rotating shaft 2222 and a carton clamping and fixing plate 2224, the carton clamping and fixing plate 2224 is located on the side of the transfer conveyor belt 210, the carton clamping and fixing plate 2224 abuts against the folding vertical carton and the transfer conveyor belt 210, one end of the turning rotating shaft 2222 is used to be connected to the rotating shaft of the turning power mechanism, and the other end of the turning rotating shaft 2222 is connected to the carton clamping and fixing plate 2224. In this embodiment, the two turning clamping and fixing members 222 are located on both sides of the transfer conveyor belt 210, for example, the carton clamping and fixing plate 2224 and the transmission direction of the transfer conveyor belt 210 are arranged parallel to each other. The flip clamping fixture 222 fixes the folding vertical carton and the transfer conveyor belt 210 by clamping. Specifically, the carton clamping fixing plates 2224 respectively abut against the side edges of the folding vertical carton and the side edges of the transfer conveyor belt 210, so that the two carton clamping fixing plates 2224 jointly clamp the folding vertical carton and the transfer conveyor belt 210, thereby keeping the folding vertical carton and the transfer conveyor belt 210 in a fixed relative position. The flipping rotating shaft 2222 serves as an extension component of the rotating shaft of the flipping power mechanism. The flipping rotating shaft 2222 is fixedly connected to the rotating shaft of the flipping power mechanism. When the rotating shaft of the flipping power mechanism rotates, the flipping rotating shaft 2222 drives the carton clamping fixing plate 2224 to rotate, so that the folding vertical carton and the transfer conveyor belt 210 are flipped synchronously, which is convenient for the carton inking printing device 300 to perform multi-sided printing, so as to improve the printing efficiency of the folding vertical carton.

[0032] For further information, see Figure 2 The folding vertical carton turning mechanism 200 further includes a clamping positioning sensor 230, which is disposed on the carton clamping fixing plate 2224. The sensing end of the clamping positioning sensor 230 faces the folding vertical carton to sense the clamping distance between the carton clamping fixing plate 2224 and the folding vertical carton. In this embodiment, the clamping positioning sensor 230 is located on the carton clamping fixing plate 2224. The clamping positioning sensor 230 serves as a sensing device for the distance between the carton clamping fixing plate 2224 and the folding vertical carton. The clamping positioning sensor 230 determines the distance between the carton clamping fixing plate 2224 and the folding vertical carton, ensures the contact between the carton clamping fixing plate 2224 and the folding vertical carton, and avoids excessive squeezing of the carton clamping fixing plate 2224 on the folding vertical carton when turning over.

[0033] In another embodiment, the flipping rotating shaft 2222 has a telescopic function to adjust the squeezing force between the carton clamping fixing plate 2224 and the folding vertical carton according to the distance sensed by the clamping positioning sensor 230. For example, the flipping rotating shaft 2222 is a telescopic rod with adjustable length; for another example, the flipping power mechanism is connected to the telescopic end of a telescopic mechanism, and the telescopic adjustment of the flipping rotating shaft 2222 is achieved through the telescopic function of the telescopic end of the telescopic mechanism.

[0034] In one embodiment, see Figure 3 The carton clamping and turning assembly 220 also includes a first clamping member 224, which includes a first clamping cylinder 2242 and a first clamping clamping plate 2244. The first clamping cylinder 2242 is connected to the carton clamping and fixing plate 2224, and the telescopic end of the first clamping cylinder 2242 is connected to the first clamping clamping plate 2244. The first clamping clamping plate 2244 and the carton clamping and fixing plate 2224 are arranged parallel to each other, and the first clamping clamping plate 2244 is used to abut against the first surface of the folding vertical carton. In this embodiment, the first holding cylinder 2242 is located on the carton clamping fixing plate 2224, and the first holding cylinder 2242 serves as the extension and retraction power source of the first holding plate 2244. Under the extension and retraction of the extension end of the first holding cylinder 2242, the first holding plate 2244 is stably held against the first surface of the folding vertical carton, so that the clamping contact area of ​​the folding vertical carton is increased, thereby increasing the clamping force of the folding vertical carton, and further enabling the first holding plate 2244 and the carton clamping fixing plate 2224 to clamp the folding vertical carton together to improve the clamping stability of the folding vertical carton.

[0035] For further information, see Figure 3 The carton clamping plate 2224 is provided with a through hole 202, and the telescopic end of the first clamping cylinder 2242 is inserted into the through hole 202, so that the first clamping plate 2244 is close to or away from the folding vertical carton. In this embodiment, the through hole 202 is provided on the carton clamping plate 2224, and the through hole 202 corresponds to the first clamping cylinder 2242. The telescopic end of the first clamping cylinder 2242 moves in the through hole 202, so that the first clamping plate 2244 abuts against the first surface of the folding vertical carton after passing through the through hole 202, thereby facilitating the first surface of the folding vertical carton to be stably clamped.

[0036] In another embodiment, the number of the first clamping members 224 is two, and the two first clamping clamps 2244 are respectively located on both sides of the folding vertical carton, the first clamping clamps 2244 correspond one-to-one to the carton clamping fixing plates 2224, and the through hole 202 is located in the middle of the first clamping clamps 2244.

[0037] In one embodiment, see Figure 2 The carton clamping and turning assembly 220 also includes a second clamping member 226, which includes a second clamping cylinder 2262 and a second clamping clamping plate 2264. The second clamping cylinder 2262 is connected to the carton clamping and fixing plate 2224, and the telescopic end of the second clamping cylinder 2262 is connected to the second clamping clamping plate 2264. The second clamping clamping plate 2264 and the carton clamping and fixing plate 2224 are arranged perpendicular to each other, and the second clamping clamping plate 2264 is used to abut against the second surface of the folding vertical carton. In this embodiment, the second clamping cylinder 2262 is located on the carton clamping plate 2224. The second clamping cylinder 2262 serves as the extension and retraction power source of the second clamping plate 2264. Under the extension and retraction of the extension end of the second clamping cylinder 2262, the second clamping plate 2264 is stably held against the second surface of the folding vertical carton, so that the fixed contact area of ​​the folding vertical carton is increased. Moreover, the second clamping plate 2264 is perpendicular to the carton clamping plate 2224, that is, the second clamping plate 2264 is parallel to the second surface of the folding vertical carton, so that the second clamping plate 2264 and the first clamping plate 2244 fix the folding vertical carton from two mutually perpendicular directions, thereby further improving the clamping stability of the folding vertical carton.

[0038] For further information, see Figure 2The second holding clamp plate 2264 includes a holding base plate 2264a and a turning connection portion 2264b connected to each other, the holding base plate 2264a abuts against the second surface of the folding vertical carton, the turning connection portion 2264b corresponds to the first surface of the folding vertical carton, and the turning connection portion 2264b is detachably connected to the telescopic end of the second holding cylinder 2262. In this embodiment, the holding base plate 2264a is parallel to the second surface of the folding vertical carton, the holding base plate 2264a is perpendicular to the first holding clamp plate 2244, and the holding base plate 2264a fixes the second surface of the folding vertical carton. The turning connection portion 2264b is located between the clamping base plate 2264a and the second clamping cylinder 2262, and the turning connection portion 2264b is also opposite to the first surface, so that the clamping base plate 2264a is connected to the telescopic end of the second clamping cylinder 2262 through the turning connection portion 2264b, so that the clamping base plate 2264a can be raised and lowered on the second surface perpendicular to the folding vertical carton, so as to facilitate clamping and squeezing the second surface of the folding vertical carton.

[0039] In one embodiment, see Figure 2 The carton clamping and turning assembly 220 also includes a third clamping member 228, and the third clamping member 228 includes a third clamping cylinder 2282 and a clamping hinge clamp 2284. The third clamping cylinder 2282 is connected to the carton clamping fixing plate 2224, and the telescopic end of the third clamping cylinder 2282 is connected to the clamping hinge clamp 2284. The clamping hinge clamp 2284 is used to abut against the third surface of the folding vertical carton, and the third surface of the folding vertical carton is perpendicular to the first surface and the second surface of the folding vertical carton. In this embodiment, the third clamping cylinder 2282 is located on the carton clamping fixed plate 2224, and the third clamping cylinder 2282 serves as the telescopic power source of the clamping hinge clamp 2284. Under the telescopic end of the third clamping cylinder 2282, the clamping hinge clamp 2284 is stably held against the third surface of the folding vertical carton, so that the fixed contact area of ​​the folding vertical carton is increased. Moreover, the contact surface between the clamping hinge clamp 2284 and the folding vertical carton is the third surface, and the third surface is perpendicular to the first surface and the second surface, so that a common clamping force is generated in three perpendicular directions of the folding vertical carton, thereby further improving the stability of the folding vertical carton when flipping. In this way, the clamping mechanisms in various directions are used to clamp the various surfaces of the folding vertical carton flat, so that the distance between the inkjet terminal and the printing surface of the folding vertical carton is uniform during printing, and uneven printing caused by warping of the surface of the folding vertical carton without clamping is avoided.

[0040] In another embodiment, the clamping hinge jaw 2284 is a hinge structure, wherein one leaf abuts against the first surface, and the other leaf abuts against the third surface and is connected to the telescopic end of the third clamping cylinder.

[0041] In another embodiment, the folding vertical carton is a cube or a cuboid, and there are two of each of the first holding member 224, the second holding member 226 and the third holding member 228, and the two first holding members 224 are arranged opposite to each other, the two second holding members 226 are arranged opposite to each other, and the two third holding members 228 are arranged opposite to each other.

[0043] In another embodiment, the number of the third clamping member 228 is one, and the third clamping member 228 abuts against the rear end face of the folding vertical carton. A liftable baffle is provided on the transfer conveyor belt 210, and the baffle is arranged opposite to the third clamping member 228. The baffle is used to rise before the folding vertical carton is turned over so as to abut against the front end face of the folding vertical carton, so that the folding vertical carton is positioned on the transfer conveyor belt 210, and the folding vertical carton is clamped together with the third clamping member 228.

[0044] In one embodiment, see Figure 2The folding vertical carton printing equipment 10 also includes a flipping power mechanism 400, which includes a flipping rotating base 410, a swing connecting shaft 420, a push-pull connecting shaft 430 and a flipping push-pull cylinder 440.

The flip rotation shaft 2222 is rotatably arranged in the rotation shaft receiving hole 402, and the push-pull connection shaft 430 is driven to move under the telescopic action of the telescopic end of the flip push-pull cylinder 440, so that the swing connection shaft 420 rotates at two connections on itself at the same time, that is, the connection between the swing connection shaft 420 and the push-pull connection shaft 430 and the flip rotation shaft 2222 rotates. In this way, when the telescopic end of the flip push-pull cylinder 440 is telescopic, the flip rotation shaft 2222 is rotated, which is convenient for flipping the folding vertical carton.

The flip rotation shaft 2222 forms a rotating fan during rotation, and the flip positioning abutment rod 454 is used to abut the flip rotation shaft 2222 when it rotates to a specified position, so that the rotation angle of the flip rotation shaft 2222 is limited within a specified range, thereby fixing the flipping angle of the folding vertical carton, making it easy to flip the surface of the folding vertical carton that needs to be flipped over for printing to face the carton inking printing device 300, so as to improve the printing alignment accuracy.

[0046] In another embodiment, the number of the flip angle positioning members 450 is two, the two flip angle positioning members 450 are arranged opposite to each other, and the rotation angle formed by the flip rotation axis 2222 and the two flip positioning abutting rods 454 respectively abutting against each other is 90°, so that the rotation angle of the flip rotation axis 2222 is 90°, which is convenient for printing operations on two adjacent vertical surfaces of the cubic folding vertical carton.

In this embodiment, the first dust removal duct 524 and the carton loading code reader 526 are both arranged on the dust removal bracket 522. The carton loading code reader 526 collects the code of the folding vertical carton to facilitate the determination of the type of the folding vertical carton, thereby facilitating the determination of whether electrostatic dust removal is required. When dust removal is required, the first dust removal duct 524 blows ionized wind to the surface of the folding vertical carton according to the information read by the carton loading code reader 526, and removes the dust on the surface of the folding vertical carton by electrostatic dust removal, so as to facilitate the subsequent ink application on the clean surface to form stable new code information.

[0051] For further information, see Figure 4The carton dust removal assembly 520 further includes a first telescopic member 528, a second telescopic member 521 and a second dust removal air duct 523. The first telescopic member 528 and the second telescopic member 521 are both connected to the dust removal bracket 522. The lifting end of the first telescopic member 528 is connected to the carton loading code reader 526 so that the carton loading code reader 526 is close to or away from the upper box conveyor belt 510; the lifting end of the second telescopic member 521 is connected to the second dust removal air duct 523 so that the second dust removal air duct 523 is close to or away from the upper box conveyor belt 510. In this embodiment, the first telescopic member 528 is used as a movable part of the carton loading code reader 526, which is convenient for telescoping the carton loading code reader 526 above the upper box conveyor belt 510, so that the carton loading code reader 526 can read the top and front and rear ends of the folding vertical carton, so as to improve the accuracy of information collection of the folding vertical carton. The second telescopic member 521 serves as a movable part of the second dust removal air duct 523. When the second telescopic member 521 is telescoped, the second dust removal air duct 523 is telescoped above the upper box conveyor belt 510, so that the second dust removal air duct 523 can perform electrostatic dust removal on the top and front and rear ends of the folding vertical carton, so as to improve the dust removal effect of the folding vertical carton.

The printing verifier 634 is used to proofread the printing on the folding vertical carton, so as to drive the rejection conveyor belt 620 to remove the folding vertical carton with incorrect printing. In this embodiment, the unloading conveyor belt 610 is arranged opposite to the printing verifier 634, and the printing verifier 634 collects and verifies the printing on the folding vertical carton to determine whether the printing on the folding vertical carton is wrong, specifically, to detect the clarity of the printing and the correctness of the coding information. The rejection conveyor belt 620 is used in conjunction with the unloading conveyor belt 610. When the printing on the folding vertical carton is correct, the printing verifier 634 sends a continue transmission signal to the unloading conveyor belt 610 and sends a stop transmission signal to the rejection conveyor belt 620, so that the folding vertical carton with correct printing enters the next normal process; and when the printing on the folding vertical carton is wrong, the printing verifier 634 sends a stop transmission signal to the unloading conveyor belt 610 and sends a start transmission signal to the rejection conveyor belt 620, so that the folding vertical carton with incorrect printing enters the NG process, so as to avoid the folding vertical carton with incorrect printing from entering the next normal process.

[0054] In another embodiment, the unloading conveyor belt includes a plurality of sequentially arranged transmission sub-belts, and a portion of the rejection conveyor belt is located between any two adjacent transmission sub-belts, so that the unloading conveyor belt and the rejection conveyor belt are embedded in each other. While ensuring that the transmission surface is flush, it is convenient to transmit the folding vertical cartons on different conveyor belts, thereby facilitating the screening of the folding vertical cartons, that is, accurately delivering the folding vertical cartons with qualified printing to the next production process, and rejecting the folding vertical cartons with unqualified printing.

[0055] In one embodiment, the present disclosure also relates to a carton printing machine, including the folding vertical carton printing device described in any of the above embodiments. In this embodiment, the folding vertical carton printing device includes a carton printing machine case, a carton turning mechanism, and a carton inking printing device.
