Description

Technical Field

[0001] The invention belongs to the technical field of marking on materials, and in particular relates to a coding device. Background Art

[0002] When products need to be printed with distinctive patterns or text, a printer station is typically fixed to an assembly line, with products being passed through the station one by one on a conveyor belt for coding. However, due to the vibrations of the conveyor belt, coding results can be poor, with issues such as skewed or overlapping prints.

[0003] To address the issue of conveyor belt jitter, some inkjet printers incorporate linear guides above the conveyor belt, with a robotic arm mounted on top. Guided by the linear guides, the robotic arm reciprocates in the conveyor's direction. The robotic arm grabs a product from the conveyor belt, and the inkjet printer inkjet prints the product while the robotic arm is moving. After coding is complete, the robotic arm places the product back on the conveyor belt for continued transport. This structure ensures product stability during coding, but the robotic arm only enables intermittent coding. After coding the previous product, the robotic arm must return to pick up the next product, resulting in low coding efficiency. Summary of the Invention

[0079] The present application provides a coding device comprising a conveyor, a track, multiple transport components, a drive component, and a spraying terminal. The conveyor is used to transport products. The track is annular with a portion of a straight segment. Each transport component is movably connected to the track and can move along the track to remove products from the conveyor. The drive component is connected to each transport component to drive each transport component to move. The spraying terminal is arranged corresponding to the straight segment of the track and is used to print codes on the products carried by the transport component.

[0080] The inkjet coding equipment is described in detail below with reference to specific embodiments.

[0081] Example 1:

[0082] See also Figures 1 to 3 , Figure 1 This is a schematic diagram of the three-dimensional structure of the coding device in Example 1 of the present application. Figure 2 This is the main view of the inkjet printer in Example 1 of the present application. Figure 3 yes Figure 2 Top view of .

[0083] like Figures 1 to 3 As shown, the present application provides a coding device 1000, which includes a conveyor 100, a track 220, a plurality of transport assemblies 300 (four in this embodiment), a drive assembly 400, and a spraying terminal 500. The conveyor 100 is used to transport products 10; the track 220 is annular, with a portion being a straight segment 230; each transport assembly 300 is movably connected to the track 220 and can move along the track 220 to remove products 10 from the conveyor 100; the drive assembly 400 is connected to each transport assembly 300 to drive each transport assembly 300 to move; and the spraying terminal 500 is disposed corresponding to the straight segment 230 of the track 220 and is used to print codes on the products 10 carried by the transport assembly 300.

[0084] In this embodiment, the spray terminal 500 marks the product 10 in a non-contact manner, which is a prior art and will not be described in detail in this application.

[0085] During operation, the transport component 300 grabs the product 10 to be coded from the conveyor 100, and moves along a circular path under the drive of the drive component 400 and the guidance of the track 220. During the movement of the transport component 300 on the straight section 230 of the track 220, the spray terminal 500 sprays codes on the product 10 to be coded carried by the transport component 300. After the coding is completed, the transport component 300 places the coded product 10 on the conveyor 100 for further transportation.

[0086] The coding equipment 1000 of the present application is provided with a plurality of transport components 300 and moves along a circular path. Two adjacent transport components 300 do not interfere with each other during the movement, and continuous coding operations can be performed, thereby improving coding efficiency.

[0087] The drive assembly 400 includes a transmission member 410 and a first driver 420. The transmission member 410 rotates about a reference axis L, which is located in the area enclosed by the track 220. The first driver 420 is used to drive the transmission member 410 to rotate. Each transport assembly 300 is movably connected to the transmission member 410 and can reciprocate radially along the reference axis L. It should be noted that the reference axis L is a virtual line to facilitate the description of the connection between the transmission member 410 and the transport assembly 300 and is not a physical component. The first driver 420 can be a motor, the axis of its shaft being the reference axis L. The transmission member 410 is fixed to the motor's shaft and rotates under the motor's drive.

[0088] In this embodiment, a plurality of transport assemblies 300 are driven to move simultaneously by one transmission member 410 , which simplifies the structure of the drive assembly 400 and facilitates drive control.

[0089] In this embodiment, track 220 is composed of two arc segments and two straight segments (one of which is straight segment 230). The two straight segments are parallel and spaced apart. The arc segments have equal radius, and each arc segment connects the two straight segments. The reference axis L is located at the midpoint of the line connecting the centers of the two arc segments. In other words, track 220 is a centrosymmetrical figure, with the reference axis L located at its center of symmetry. This structure ensures that the speed of each transport assembly 300 is relatively uniform during one rotation along track 220. Of course, the reference axis L can also be located at other locations within the area enclosed by track 220.

[0090] Preferably, the motion paths of the plurality of transport assemblies 300 relative to the transmission member 410 are evenly distributed in the circumferential direction of the reference axis L. In this way, the time intervals between the inkjet printing operations of two adjacent transport assemblies 300 are consistent, which facilitates the control of the movement of the inkjet printing terminal 500.

[0091] Specifically, to enable the transport assembly 300 to be movably connected to the transmission member 410 and to reciprocate radially along the reference axis L, the transmission member 410 is provided with a plurality of transmission slots 411, each corresponding to a plurality of transport assemblies 300. Each transmission slot 411 extends radially along the reference axis L and has two opposing first sidewalls 411a. The transport assembly 300 includes a transport body 310 and a first roller 320. The transport body 310 is used to remove products 10 from the conveyor 100. The first roller 320 is rotatably mounted on the transport body 310 about its axis. The first roller 320 is sandwiched between the two first sidewalls 411a and moves along the extension direction of the transmission slot 411.

[0092] The first roller 320 rolls back and forth in the transmission groove 411 along the extension direction of the transmission groove 411 (radially of the reference axis L), thereby realizing the movable connection between the transport assembly 300 and the transmission member 410. At the same time, in this connection mode, when the transport assembly 300 moves relative to the transmission member 410, the friction force is relatively small.

[0093] See also Figure 4 and Figure 5 , Figure 4 This is a three-dimensional structural diagram of the cooperation between the transport component and the track portion in the first embodiment of the present application. Figure 5 yes Figure 4 Middle AA section view.

[0094] like Figure 4 and Figure 5As shown, a side surface 210 of the track portion 200 is recessed to form a track 220, which has two opposing second side walls 221. The transport assembly 300 also includes a second roller 330, which is rotatably mounted on the transport body 310 about its axis. The second roller 330 is sandwiched between the two second side walls 221 and moves along the extension direction of the track 220.

[0095] The second roller 330 rolls in the track 220 along the extension direction of the track 220 , thereby achieving a movable connection between the transport assembly 300 and the track 220 . Meanwhile, when the transport assembly 300 moves relative to the track 220 , the friction force is relatively small.

[0096] Furthermore, the track 220 has a bottom surface 222 connected between the two second side walls 221. The bottom surface 222 is flat at least in the straight section 230. The end of the second roller 320 (in this embodiment, the end of the rotating shaft of the second roller 320) contacts the bottom surface 222. When the transport assembly 300 moves relative to the track 220 in the straight section 230, it always contacts the bottom surface 222. This ensures that the transport assembly 300 does not jump in a direction perpendicular to the bottom surface 222, ensuring smooth movement and good inkjet printing effect.

[0097] Specifically, the transport body 310 includes a structural member 311, a suction nozzle unit 313 and a second driver 312. The suction nozzle unit 313 is used to suck the product 10, which is a prior art and will not be described in detail here. The second driver 312 is connected between the suction nozzle unit 313 and the structural member 311, and is used to drive the suction nozzle unit 313 to reciprocate relative to the structural member 311. The second driver 312 can be a cylinder. Among them, the second roller 330 is rotatably arranged on the structural member 311 around its axis. Before coding, the second driver 312 drives the suction nozzle unit 313 to move toward the distal end to pick up the product 10 to be coded from the conveyor 100. After picking up the product 10 to be coded, the second driver 312 drives the suction nozzle unit 313 to move toward the proximal end to drive the product 10 to be coded to move, so as to avoid the product 10 to be coded from rubbing against the conveyor 100. After coding, the second driver 312 drives the nozzle unit 313 to move toward the far end to place the coded product 10 on the conveyor 100. After placing the coded product 10, the second driver 312 drives the nozzle unit 313 to move toward the near end to wait for the next product 10 to be coded.

[0098] More specifically, the structural member 311 includes a first connecting plate 3111 and a second connecting plate 3112. The second connecting plate 3112 is integrally connected to the first connecting plate 3111 to form an "L" shape. The first connecting plate 3111 is parallel to the surface 210 of the main body 210 of the track portion 200 and is spaced apart from the surface 210. The second roller 330 is rotatably mounted on the first connecting plate 3111 about its axis, with the axis of the second roller 330 perpendicular to the first connecting plate 3111. The second connecting plate 3112 is perpendicular to the surface 210 of the track portion 200 and is spaced apart from the outer side of the track portion 200.

[0099] More specifically, the second actuator 312 includes a cylinder body 3121 and a piston rod 3122. The piston rod 3122 is mounted on the cylinder body 3121 and is capable of reciprocating relative to the cylinder body 3121 along its axis. The second actuator 312 can be a pneumatic cylinder or an oil cylinder. The cylinder body 3121 is fixed to the second connecting plate 3112, and the nozzle unit 313 is fixed to the end of the piston rod 3122.

[0100] Optionally, the conveyor 100 includes a first conveying assembly 110 and a second conveying assembly 120. The first conveying assembly 110 and the second conveying assembly 120 have the same transmission direction and are spaced apart. The first conveying assembly 110 and the second conveying assembly 120 can be belt conveyors in the prior art.

[0101] The first conveying assembly 110 may be used to convey the product 10 to be coded, and the second conveying assembly 120 may be used to convey the product 10 after coding.

[0102] To facilitate the transport assembly 300 in removing the product 10 to be coded from the exit of the first conveyor assembly 110, the conveyor 100 also includes a stopper 130, which is positioned at the exit of the first conveyor assembly 110. The stopper 130 may be an angle iron. After the product 10 to be coded is conveyed to the exit of the first conveyor assembly 110, it is stopped by the stopper 130, halting its movement and waiting to be removed (or sucked) by the transport assembly 300. When the product 10 to be coded is stationary, it is more easily removed by the transport assembly 300.

[0103] Example 2:

[0104] See also Figure 6 and Figure 7 , Figure 6 This is the main view of the inkjet printer in Example 2 of the present application. Figure 6 The conveyor and spray terminal are omitted. Figure 7 yes Figure 6 BB cross-sectional view in the embodiment. In the second embodiment, the focus is on the parts that are different from the first embodiment. In addition, the same reference numerals are given to the same structures as the first embodiment, and the description of the structures is omitted.

[0105] like Figure 6 and Figure 7 As shown, the coding device 2000 includes a track 600 , a driving assembly 800 and a plurality of transport assemblies 700 .

[0106] The track 600 is annular, a portion of which is a straight line segment, and a cross section of which is rectangular.

[0107] The drive assembly 800 includes a transmission member 810 and a first driver 820. The transmission member 810 rotates about a reference axis P, which extends through the area enclosed by the track 600. The first driver 820 is used to drive the transmission member 810 to rotate. The transmission member 810 is disposed above the track 600. A plurality of transmission bosses 811 are projecting from the side of the transmission member 810 facing the track 600. Each transmission boss 811 extends radially along the reference axis P. The plurality of transmission bosses 811 are evenly distributed circumferentially about the reference axis P and correspond one-to-one with the plurality of transport assemblies 700.

[0108] Each transport assembly 700 includes a transport body 710, a mounting shaft 720, a first connector 730, and a second connector 740. The transport body 710 is used to pick up products 10. The mounting shaft 720 is fixed to the transport body 710. The first connector 730 is rotatably disposed at one end of the mounting shaft 720 about its axis. It slidably engages with the transmission boss 811 and can reciprocate along the extension direction of the transmission boss 811. The second connector 740 is rotatably disposed at the other end of the mounting shaft 720 about its axis. It slidably engages with the track 600 and can move along the extension direction of the track 600.

[0109] This embodiment provides another transmission matching structure, so that the driving assembly 800 can simultaneously drive multiple transport assemblies 700 to move along the track 600. At the same time, another structure of the track 600 is also provided.

[0110] In addition, other structures and effects are the same as those of the above-mentioned embodiment 1 and will not be described again here.

[0111] In summary, this application has at least the following advantages:

[0112] Multiple transport components are set up, and each transport component moves along a circular path. Two adjacent transport components do not interfere with each other during the movement, and continuous coding operations can be performed, thereby improving coding efficiency.
