Description

Technical Field

[0001] The invention relates to a marking device, in particular to a cantilever automatic marking device which integrates the advantages of both submerged and frame-type marking devices. Background Art

[0002] At present, the automatic labeling equipment available on the market mainly has two structural types: submerged type and frame type.

[0003] The submerged labeling equipment refers to a device where the nozzle is installed in a lifting mechanism below the bale conveying device. When the cotton bale is in place, it passes over the nozzle. When the bale is in place and the label printing begins, the nozzle rises from one end of the bale below the height of the bottom surface of the bale to complete multiple lines of printing. Although the submerged labeling equipment has high integration, compact structure, small footprint, easy installation, and little impact on the original production line, it is inconvenient to maintain due to the low installation position of the equipment and the small space.

[0004] Frame-type labeling equipment refers to a device where the nozzle is installed in a square frame across the bale conveyor. When the bale is in place and the label printing begins, the nozzle descends from a position higher than the top of the bale at one end to complete multiple lines of printing. However, frame-type labeling equipment is large in size, occupies a large area, has requirements for installation space, and is not suitable for installation in small spaces.

[0005] In addition, the existing automatic marking equipment still has the following problems: ① The positioning mechanism and control system are both single-stage control modes, relying on controlling the movement of the cotton bale to achieve the relative position of the cotton bale and the nozzle. The control accuracy is greatly affected by the cotton bale conveying speed, and is not suitable for fast-speed bale conveying devices and has poor adaptability; ② They all use rigid nozzles, which are difficult to adapt to cotton bales with inclined or uneven end faces, thus affecting the marking effect; ③ They all use disposable imported ink cartridges, which are discarded when the ink is used up, which is not only a waste of resources, but also causes high costs for users to use consumables. Summary of the invention

[0006] In view of the above problems, the purpose of the present invention is to provide a cantilevered automatic marking device, which integrates the advantages of both submerged and frame-type marking devices. It not only has a more reasonable structure, occupies less space, is easy to install and maintain, and has a low manufacturing cost, but also adopts two-stage control, and the position control of the cotton bale and the nozzle is more precise. It can be used for all users and has strong adaptability. At the same time, it also innovates a flexible nozzle with good marking effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figure 1As shown, the cantilever automatic labeling equipment provided by the present invention includes: a column and a nozzle lifting and moving mechanism 1, which is arranged on one side of the package conveying device 11, and the column and the nozzle lifting and moving mechanism 1 has a lifting action end that can reciprocate vertically; a cantilever 2, which is horizontally installed at the lifting action end of the column and the nozzle lifting and moving mechanism 1; a nozzle horizontal movement mechanism 3, which is installed in the cantilever 2, and the nozzle horizontal movement mechanism 3 has a horizontal action end that can reciprocate horizontally along the cantilever 2; a nozzle rotating mechanism 4, which is installed at the horizontal action end of the nozzle horizontal movement mechanism 3, and the nozzle rotating mechanism 4 has a rotating action end that rotates in a horizontal plane; a nozzle feeding mechanism 5, which is installed at the rotating action end of the nozzle rotating mechanism 4, and the nozzle feeding mechanism 5 has a feeding action end that can reciprocate horizontally in a direction perpendicular to the cantilever 2; a flexible nozzle mechanism 6, which is installed at the feeding action end of the nozzle feeding mechanism 5, and the flexible nozzle mechanism 6 is configured to be freely retractable forwards and backwards when subjected to pressure increase or decrease.

[0032] In the above embodiment, preferably, Figure 3 As shown, the column and nozzle lifting mechanism 1 adopts a synchronous belt mechanism with a balancing part, and the nozzle lifting mechanism 1 includes: a bottom column 102, which is fixed to one side of the package conveying device 11 through a base 101; a top column 103, which is arranged on the upper part of the bottom column 102 to form an installation base for all lifting and moving parts; a lifting guide slider 104, which is arranged on the top column 103 and can move up and down in the vertical direction; a cantilever mounting plate 105, which is fixed on the lifting guide slider 104, one end of the cantilever 2 is fixedly connected to the cantilever mounting plate 105, and the other end of the cantilever 2 is suspended; a driving shaft 107 and a driven shaft 111, which are rotatably arranged on the top column 103 located at the upper and lower ends of the lifting guide slider 104 through a bearing seat 109; a synchronous gear 115, two synchronous gears 115 are respectively installed on the driving shaft 107 and the driven shaft 111; the synchronous toothed belt 108 is connected between the two synchronous gears 115; the toothed plate 106 is used to connect the cantilever mounting plate 105 and the synchronous toothed belt 108; the counterweight block 110 is arranged on one side of the synchronous toothed belt 108 and is connected to the synchronous toothed belt 108 through the synchronous toothed plate; the tensioning mechanism 112 is arranged on both sides of the bearing seat 109 located at the bottom, and is used to adjust the tightness of the synchronous toothed belt 108; the position sensor 113, two position sensors 113 are arranged on the top column 103, and are used to mark the zero position and the limit position of the cantilever mounting plate 105; the motor and the reduction mechanism 114 are connected to the driving shaft 107 through the reduction mechanism bracket 116. Therefore, when the motor and the reduction mechanism 114 rotate, the driving shaft 107 and the synchronous gear 115 thereon are driven to rotate. When the synchronous gear 115 rotates, it drives the synchronous belt 108 to achieve up and down movement. The synchronous belt 108 drives the cantilever mounting plate 105 to achieve lifting movement through the toothed plate 106.

[0033] In the above embodiment, preferably, Figure 4 As shown, the nozzle horizontal motion mechanism 3 adopts a high-precision synchronous belt mechanism, and the nozzle horizontal motion mechanism 3 includes: an X-axis motor and a reduction mechanism 301, which is arranged on the cantilever 2 near the column and the nozzle lifting motion mechanism 1; an X-axis synchronous gear 302, which is connected to the output end of the X-axis motor and the reduction mechanism 301; an X-axis synchronous gear idler 303, which is arranged on the cantilever 2 away from the column and the nozzle lifting motion mechanism 1; an X-axis synchronous belt 304, which is connected between the X-axis synchronous gear 302 and the X-axis synchronous gear idler 303; an X-axis tensioning mechanism 305, which is arranged near the X-axis synchronous gear idler 303. On the cantilever 2, it is used to adjust the tightness of the X-axis synchronous belt 304; the X-axis guide slider 306 is arranged on the cantilever 2 along the length direction of the cantilever 2, and the nozzle rotating mechanism 4 is installed on the X-axis guide slider 306; the X-axis synchronous belt toothed plate 307, one side of the X-axis synchronous belt toothed plate 307 is arranged on the X-axis synchronous belt 304, and the other side of the X-axis synchronous belt toothed plate 307 is fixedly connected to the nozzle rotating mechanism 4, which is used to realize the synchronous movement of the X-axis synchronous belt 304 and the nozzle rotating mechanism 4; the X-axis zero position sensor 308 is arranged on the cantilever 2 at the starting end of the X-axis guide slider 306, which is used to mark the zero position of the X-axis. Therefore, when the X-axis motor and the reduction mechanism 301 move, the X-axis synchronous gear 302 is driven to rotate, and the X-axis synchronous gear 302 drives the X-axis synchronous belt 304 to move horizontally, so that the X-axis synchronous belt 304 drives the nozzle rotating mechanism 4 to realize horizontal reciprocating motion.

[0034] It should be pointed out that in the above embodiments, the column and nozzle lifting motion mechanism 1 and the nozzle horizontal motion mechanism 3 are only described by taking the synchronous belt mechanism as an example. In order to achieve the same purpose, the column and nozzle lifting motion mechanism 1 and the nozzle horizontal motion mechanism 3 can also adopt a gear rack mechanism or a sprocket chain mechanism. Of course, in the specific implementation process, any other driving form that can achieve the same motion function is acceptable and should belong to the protection scope of the present invention.

[0035] In the above embodiment, preferably, Figure 5As shown, the nozzle rotating mechanism 4 adopts a high-precision gear rack mechanism, and the nozzle rotating mechanism 4 includes: a mounting base 401, which is arranged on the X-axis guide rail slider 306; a rotating nozzle base plate 402, which is arranged on the mounting base 401; an external gear swivel support 403, the top of the external gear swivel support 403 is fixedly connected to the bottom of the rotating nozzle base plate 402, and the lower part of the external gear swivel support 403 can realize swivel motion; a swivel connection flange 404, which is arranged at the bottom of the external gear swivel support 403 and can move synchronously with the external gear swivel support 403 , and the bottom of the rotating connection flange 404 is connected to the nozzle feeding mechanism 5; the rotating motor and the reduction mechanism 405 are arranged on the upper part of the rotating nozzle substrate 402; the rotating shaft 406 is connected to the output end of the rotating motor and the reduction mechanism 405; the rotating driving gear 407 is fixedly connected to the rotating shaft 406 and meshes with the external gear rotary support 403 to drive the external gear rotary support 403 to realize rotary motion; the rotating zero position sensor 408 is arranged on the rotating nozzle substrate 402 and is used to mark the zero position of the nozzle rotating mechanism 4. Therefore, when the rotating motor and the reduction mechanism 405 rotate, the rotating driving gear 407 is driven to rotate through the rotating shaft 406, the rotating driving gear 407 drives the external gear rotary support 403 to rotate, and the external gear rotary support 403 drives the rotating connection flange 404 to rotate, thereby driving the nozzle feeding mechanism 5 installed at the bottom of the rotating connection flange 404 to do reciprocating rotary motion to realize the rotation of the nozzle.

[0036] It should be pointed out that in the above embodiment, the nozzle rotating mechanism 4 is only described by taking the gear rack mechanism as an example. In order to achieve the same purpose, the nozzle rotating mechanism 4 can also adopt a sprocket chain mechanism. Of course, in the specific implementation process, any other driving form that can achieve the same motion function is acceptable and should belong to the protection scope of the present invention.

[0037] In the above embodiment, preferably, Figure 6 As shown, the nozzle feeding mechanism 5 includes: a base 501, which is fixedly connected to the rotating connection flange 404 of the nozzle rotating mechanism 4; a bottom plate 502, which is slidably connected to the bottom of the base 501 through a feeding guide slider 503, and the flexible nozzle mechanism 6 is installed on the bottom plate 502; an electric push rod 504, which is horizontally installed in the base 501, and the fixed end of the electric push rod 504 is fixedly connected to the base 501 through a push rod bracket 505, and the action end of the electric push rod 504 is fixedly connected to the bottom plate 502 through the push rod bracket 505. Therefore, the bottom plate 502 forms the feeding action end of the nozzle feeding mechanism 5, and when the electric push rod 504 is extended and retracted, it drives the bottom plate 502 to reciprocate on the base 501, thereby driving the flexible nozzle mechanism 6 to move.

[0038] In the above embodiment, preferably, the degree of fit between the nozzle and the end surface of the cotton bale directly affects the effect of marking. However, the end surface of the cotton bale actually produced always has different degrees of undulations. Rigid nozzles often make the distance between the nozzle and the end surface of the cotton bale sometimes large and sometimes small due to the uneven end surface of the cotton bale, resulting in unclear marking. Figure 7 As shown, the present invention innovatively designs a flexible nozzle mechanism 6, which includes: a hanging plate 601, which is slidably connected to the bottom of the base plate 502 of the nozzle feeding mechanism 5 through a linear guide slider 602, and the hanging plate 601 has an outwardly protruding suspended end; a nozzle 603, which is suspended at the suspended end of the hanging plate 601; a fixed block 604, wherein two fixed blocks 604 are fixed on the hanging plate 601 at intervals along the sliding direction of the hanging plate 601; a spring block 605, which is slidably arranged on the hanging plate 601 between the two fixed blocks 604; a spring guide rail 606, which is supported between the two fixed blocks 604; a spring 607, which is sleeved on the spring guide rail 606, and one end of the spring 607 abuts against the fixed block 604, and the other end of the spring 607 abuts against the spring block 605. Therefore, when the nozzle 603 is blocked by external force, the nozzle 603 will drive the hanging plate 601, the spring block 605 and the slider on the linear guide slider 602 to move backward, and at the same time the spring block 605 will compress the spring 607. When the external resistance disappears, the spring 607 stretches freely and pushes the nozzle 603 to rebound.

[0043] The cantilever automatic labeling device provided by the present invention has the following working process when it is working:

[0044] The cotton bale 10 moves on the bale conveying device 11. When it reaches the cotton bale positioning sensor 201, the PLC controller 701 receives the signal of the cotton bale positioning sensor 201 and stops the bale conveying device 11 through the bale conveying device control module 704. After the flexible nozzle mechanism 6 descends to the height specified by the PLC controller 701, the nozzle feeding mechanism 5 drives the flexible nozzle mechanism 6 to move forward under the control of the PLC controller 701, and the nozzle 603 is pressed against the cotton bale 10 for compression. When the cotton bale positioning sensor 209 on the top of the flexible nozzle mechanism 6 is triggered, the PLC controller 701 receives the signal of the cotton bale positioning sensor 209 and the PLC controller 701 controls the nozzle feeding mechanism 5. The nozzle 603 stops moving. At this time, the nozzle 603 is completely close to the cotton bale 10 and prints line by line. After the first side is printed, the nozzle feeding mechanism 5 retreats under the control of the PLC controller 701, and the flexible nozzle mechanism 6 retreats with the nozzle feeding mechanism 5. When the nozzle feeding mechanism 5 triggers the zero position sensor 207 for the electric push rod, it stops retreating. Under the control of the PLC controller 701, the cantilever 2 rises, and the nozzle rotating mechanism 4 drives the nozzle feeding mechanism 5 to rotate 180° clockwise to complete the printing of the first side. At this time, the PLC controller 701 starts the bag conveying device 11 through the bag conveying device control module 704 to continue to drive the cotton bale 10 to move forward. When the other end face of the cotton bale 10 When leaving the cotton bale positioning sensor 209, the PLC controller 701 receives the signal of the cotton bale positioning sensor 209, stops the bale conveying device 11 through the bale conveying device control module 704, and after the flexible nozzle mechanism 6 drops to the height specified by the PLC controller 701, the nozzle feeding mechanism 5 drives the flexible nozzle mechanism 6 to move forward under the control of the PLC controller 701, and the nozzle 603 is pressed against the cotton bale 10 for compression. When the cotton bale positioning sensor 209 on the top of the flexible nozzle mechanism 6 is triggered, the PLC controller 701 receives the signal of the cotton bale positioning sensor 209, and the PLC controller 701 stops the nozzle feeding mechanism 5, at which time the nozzle 603 is completely pressed against the cotton bale 10. Package 10 is printed line by line. After the second side is printed, the nozzle feeding mechanism 5 retreats under the control of the PLC controller 701, and the flexible nozzle mechanism 6 retreats with the nozzle feeding mechanism 5. When the nozzle feeding mechanism 5 triggers the electric push rod with the zero position sensor 207, it stops retreating. Under the control of the PLC controller 701, the cantilever 2 rises, and the nozzle rotating mechanism 4 drives the nozzle feeding mechanism 5 to rotate 180° counterclockwise to complete the printing of the second side. At this time, the PLC controller 701 starts the package conveying device 11 through the package conveying device control module 704 to continue to drive the cotton bale 10 to move forward and transport the cotton bale 10 away. The entire marking work is completed, waiting for the next cotton bale to arrive.
