Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] Combination Figures 1-4 This embodiment discloses a flexible label front and back material handling device, specifically including a material handling turntable 1 that can rotate stepwise around its own axial center line. The bottom of the material handling turntable 1 is connected to a stepper rotary motor 11. Three material handling trays 2 are centrally symmetrically arranged on the material handling turntable 1. The top of the material handling trays 2 is provided with a sink 21 for holding flexible labels. After the material handling trays 2 are moved stepwise, they form a feeding station, a material handling station and a discharging station.

[0027] A vibrating feeder 3 for supplying flexible labels is set on the outside of the feeding station. To ensure that the number of labels input each time is appropriate, a weighing hopper 31 is also set at the output end of the vibrating feeder 3. The labels of threshold weight are input in batches through the opening and closing control structure.

[0028] Above the material handling station is a material handling device for adjusting the front and back of the labels. Specifically, the material handling device includes a material handling bracket 4 for connecting to an external carrier. The material handling bracket 4 is a horizontal plate structure. Lifting cylinders 41 are installed at the bottom of the left and right sides of the material handling bracket 4. The telescopic rod of the lifting cylinder 41 extends vertically upward through the material handling bracket 4 and is connected to two vertically arranged pull rods 43 via a connecting rod 42. There are four pull rods 43 arranged symmetrically on the left and right sides. The pull rods 43 pass through the material handling bracket 4 through sliding bushings. The bottom of the pull rods 43 is connected to the material box 5. The lifting cylinders can control the vertical lifting and lowering of the material box 5 to adjust the distance between the bottom of the material box 5 and the material handling tray 2. After lifting, the distance increases and will not interfere with the rotation of the material handling turntable 1.

[0029] The material bin 5 can be lowered and placed on top of the material tray 2 at the material handling station, so that the inner side of the material bin 5 and the material tray 2 form a compaction cavity. The top of the material bin 5 has an opening, and a transparent observation plate 7 is provided at the opening. The observation plate 7 is detachably connected to the top of the material bin 5 by bolts. The visual recognition module 6 is located on the material handling bracket 4 above the observation plate 7, and can detect and identify the front and back of the labels in the compaction cavity through the observation through hole 44 on the material handling bracket 4 and the observation plate 7 below. Specifically, it detects the number of internal labels in the front position.

[0030] The material bin 5 is equipped with a tamping drive structure, which can control the label in the tamping cavity to flip and / or relocate. Specifically, in conjunction with... Figure 3 and Figure 4 In this embodiment, several ventilation holes 51 are evenly distributed on the four side walls of the material box 5. The inner diameter of the ventilation holes 51 is smaller than the outline of the label. This structure ensures air communication between the inner cavity of the material box and the external space without causing label leakage. Air blowing interfaces 52 are provided on the left and right sides of the material box 5 for connecting to pulse air pipes. The air blowing interfaces 52 can blow pulsed air into the inner cavity of the material box, forming the material box driving structure. The air blowing interfaces 52 are located close to the bottom of the material box 5, so that the blowing position is as close as possible to the bottom of the material tray 2, in order to blow up more labels. After the labels are blown up, they flip over, which helps to flip the labels that were originally facing up. After each blowing, the visual recognition module 6 will re-detect, and the material box 5 will detach from the material tray 2 after reaching a threshold condition. The visual recognition module 6 uses a CCD camera to acquire images and uses image processing algorithms to analyze and recognize the acquired images. This is existing technology, and its specific structure and working principle will not be described in detail here. Those skilled in the art can select and implement it from existing technologies according to actual operating conditions.

[0031] To improve the working quality of the visual recognition module 6, lighting lamps 61 are also provided on the front and rear sides of the material handling bracket 4 to provide sufficient light brightness to the inner cavity of the material handling.

[0032] In other embodiments, the material-driving structure is a vibrator mounted on the material box 5, which uses vibration to achieve the flipping operation of the label in the material-driving cavity; or a vortex blowing device is used to increase the airflow direction by using a spiral air outlet to improve the success rate of label flipping.

[0033] Furthermore, a vertical buffer rod 54 is movably connected to the outer wall of the material box 5. A stop block 53 is connected to the bottom of the buffer rod 54. A buffer spring (not shown in the figure) is provided between the stop block 53 and the material box 5. The buffer spring is sleeved on the buffer rod 54. Its function is to ensure that the stop block 53 can tightly abut against the material tray 2 below after it moves down, thereby ensuring the closure of the bottom gap and preventing the internal label from escaping.

[0034] During operation, the vibrating feeding tray periodically outputs flexible labels. After quantitative diversion at the weighing hopper 31, the flexible labels are conveyed to the sorting tray 2 at the feeding station, and then transferred to the sorting station. The material box 5 descends and abuts against the sorting tray 2 to form a compaction cavity. The vision recognition module 6 detects the front and back of the labels. When the number of front labels is less than a threshold, such as... Figure 4 As shown, the air blowing interface uses an external pulse air pipe to blow air into the inner cavity of the material, causing the labels inside to tumble and shift, achieving changes in orientation and position. The visual recognition module 6 continues to detect the front and back of the labels. When the number of front labels detected reaches or exceeds the threshold, the material box 5 moves upward, and the material handling turntable 1 continues to rotate, waiting for the external transfer mechanism to accurately output the label position information obtained by the visual recognition module 6.

[0035] In practical implementation, appropriate materials and components can be selected for assembly and debugging according to actual needs. For example, the material handling turntable 1 can be made of stainless steel to improve its corrosion resistance and service life; the vibrating feed tray 3 can use an electromagnetic vibrator as a power source to achieve orderly label conveying; the visual recognition module 6 can use a high-performance industrial camera and image processing algorithm to improve the accuracy and speed of image recognition; the material tamping drive structure can be combined with components such as vibrators or pulse blowing devices according to actual needs.

[0036] During the debugging process, the speed and step angle of the stepper rotary motor 11 need to be adjusted to ensure that the material handling tray 2 can move in the predetermined order and position. At the same time, the vibration frequency and amplitude of the vibrating feed tray 3 also need to be adjusted to ensure that the labels can be conveyed with a certain spacing and posture. In addition, the vision recognition module 6 needs to be calibrated and debugged to ensure that it can accurately and quickly identify the front and back of the label; and the material handling drive structure needs to be adjusted and optimized to improve the material handling effect and efficiency.

[0037] After debugging, the flexible labels can be placed into the vibrating feed tray 3, and the device can be started to perform automated material handling and sorting operations. During operation, the label status in the compaction cavity can be monitored in real time by observing the output results of the transparent observation plate 7 and the monitoring vision recognition module 6; at the same time, the parameters and action mode of the compaction drive structure can be adjusted according to actual needs to meet the production requirements of different products.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
