Description

Technical Field

[0001] The present invention relates to the technical field of goods coding, and in particular to a coding machine based on goods coding on a pallet. Background Art

[0002] Online shopping is an indispensable life need for young people in the new era, so the express logistics industry has also developed rapidly. In the past two years, with the continuous increase in logistics labor costs, many large logistics and express companies have established unmanned warehouses with fully automated robot operations to achieve fully automatic unmanned warehousing logistics operations, referred to as unmanned warehousing logistics, also known as smart logistics. The so-called warehousing logistics is to use self-built or leased warehouses, sites, storage, custody, loading and unloading, and distribution of goods, and a barcode sticking machine is required to manually stick barcodes on the goods. The process is complicated and cumbersome. When sticking the barcode, the direction of rotation is required to stick the barcode on the goods. Due to the different shapes of the goods, the position of the code may also be different. For example, a rectangular package may need to be stuck on two sides or four sides. The existing technology needs to control the rotating motor through a single-chip microcomputer or PLC, but it undoubtedly puts a burden on the system software, and the frequent starting and stopping of the motor will also shorten its service life.

[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0028] Embodiment: A labeling machine based on pallet cargo labeling, referring to Figure 1 shown.

[0029] A labeling machine based on labeling pallet goods, comprising a rotating table 1 and a plurality of pallets 2 mounted on the rotating table 1 and rotating with the rotating table 1, a device with the pallet 2 as a working position is fixedly mounted on the outer edge of the rotating table 1, and the device comprises a feeding device 3, a labeling device 7 and a discharging device 4;

[0030] The tray 2 is rotatably connected to the rotating table 1. A spline bearing 23 is fixedly connected to the middle of the tray 2. The spline bearing 23 is connected to a spline shaft 24. The spline shaft 24 extends downward and is fixedly connected to a rotating wheel 22 at the end. The spline shaft 24 and the spline bearing 23 are arranged to realize the extension and retraction of the spline shaft 24 in the spline bearing 23.

[0031] The rotating wheel 22 is connected with a convex portion 222, and the convex portion 222 has a limited state when rotating or moving, in which the outermost edge of the convex portion 222 extends a maximum distance from the outer edge of the rotating wheel 22;

[0032] Specifically, refer to Figure 2-4 As shown, the convex portion 222 is a cam structure, such as Figure 3 and 4 As shown, the rotating wheel 22 is composed of sub-wheels 223 which are distributed up and down and coaxially fixedly connected. The protrusion 222 is accommodated between the two sub-wheels and is rotationally connected to any one of the sub-wheels 223 and is driven by a motor.

[0033] Refer to Figure 3 Through rotation, the portion 222 has two extreme states, namely, being completely received in the rotating wheel 22 or protruding out of the rotating wheel 22.

[0034] In addition, in this embodiment, a fixing protrusion 221 is fixedly installed on the outer edge of the rotating wheel 22 , and the fixing protrusion 221 protrudes from the outer edge of the rotating wheel 22 .

[0035] The bottom of the rotating table 1 is fixedly installed with an installation box 21, the rotating wheel 22 is located in the installation box 21, the spline shaft 24 penetrates the rotating table 1 and is exposed from the rotating table 1, and the spline bearing 23 is exposed from the upper end surface of the rotating table 1 and connected to the tray 2;

[0036] The spline shaft 24 is sleeved with a spring, one force-bearing end of the spring abuts against the lower end surface of the rotating table 1, and the other force-bearing end of the spring abuts against the upper end surface of the rotating wheel 22;

[0037] A limit block 25 is fixedly installed on the inner wall of the installation box 21;

[0038] A friction wheel 26 is installed at the bottom of the rotating wheel 22. The friction wheel 26 is installed vertically and driven by a motor to rotate around a horizontal axis. The friction wheel 26 and the rotating wheel 22 are in contact with each other, and the contact point is offset from the axis of the rotating wheel 22.

[0039] The friction wheel 26 is a cam and is driven by a motor;

[0040] Under the action of the spring, the friction wheel 26 has a contact point with the rotating wheel 26. When the friction wheel 26 rotates, the contact point has two extreme positions: the highest position and the lowest position. When it is at the highest position, the limit block 25 is on the rotation path of the protrusion 222 in the limited state. When the two are in contact, the rotation movement of the rotating wheel 26 is limited and stopped; when it is at the lowest position, the rotation paths of the limit block 25 and the protrusion 222 are staggered.

[0041] The rotation angle of the tray can be adjusted by the above rotating wheel 22, convex part 222, fixed convex block 221, limit block 25 and friction wheel 26. The actual use is described in detail below.

[0042] The rectangular packaging box is input from the feeding device 3 onto the tray 2, and the rotating table 2 rotates and delivers it to the front end of the coding device 7. At this time, the rotating table 2 stops rotating and the coding device 7 performs the coding operation. If the coding needs to be applied to the four sides of the packaging box, it needs to be rotated 90 degrees three times.

[0043] Reference Figure 3 As shown, in order to save operating costs, this embodiment is provided with two fixed protrusions 221 distributed at 180 points, and two adjustable protrusions 222 as shown in the figure. Figure 7 As shown, in order to achieve the four-sided code, the convex portion 222 is adjusted to Figure 7 The state shown in the third figure is that the outer edge of the rotating wheel 22 presents a convex structure of four equally divided annular arrays. Figure 2 As shown, when the friction wheel 26 rotates, if the rotating wheel 22 is limited by the first protruding structure and the limiting plate 25, the friction wheel 26 rotates by itself, and the rotating wheel 22 does not move. Figure 2 The position of the rotating wheel 22 is set, and under the action of the spring, the rotating wheel 22 sinks, the protruding structure separates from the limiting plate 25, and the friction wheel 26 drives the rotating wheel 22 to rotate and lift upward. When it rotates to the second protruding structure abutting, the rotating wheel 22 stops. At this time, the rotating wheel has rotated 90 degrees. And so on. There are a total of four protruding structures, which are configured to rotate 90 degrees three times to ensure that each side of the carton can be coded (the coding is completed during the interval time of the friction wheel's own rotation).

[0044] In summary, adjustments can also be made according to actual conditions, such as limiting the angle of the protruding structure to limit the angle of each rotation and adapt to different coding requirements for packaging boxes of different shapes.

[0045] On this basis, in order to facilitate loading and unloading, and to place the packaging box at a fixed angle when loading, a manipulator 53 is installed on the feeding device 3 and the discharging device 4. A vertical cylinder 52 is fixedly installed on the upper end of the manipulator 53. The base of the vertical cylinder 52 is fixed on a slider, and the slider is fixedly installed with a horizontal cylinder 51. The packaging box is transferred by the cooperation of the horizontal cylinder 51 and the vertical cylinder 52.

[0046] In addition, an operating table can be set on one side of the discharging device 4 to arrange manual coding inspection. Since the packaging box is coded on multiple sides, it needs to be turned over for easy observation.

[0047] Reference Figure 5 As shown, the discharging device 4 also includes a conveyor, on which a flip assembly is installed. The flip assembly includes an L-shaped plate 42, and a rotating shaft 44 is fixedly installed in the middle of the L-shaped plate 42. The rotating shaft 44 is driven by a motor. A return spring 43 is connected to the end of the L-shaped plate 42 close to the input, and the other end of the return spring is fixed to the frame of the discharging device 4. Referring to the figure, the flip assembly is installed between the conveying wheels 41 of the conveyor.

[0048] Two sets of flipping components can also be installed, flipping it twice for easier observation. In addition, a code scanning device 45 can be installed at the output end of the conveyor to perform shipment inspection by scanning the code. And under the action of the flipping component, the packaging box can pass the code scanning device 45 and be directly output.
