Description

Technical Field

[0001] The utility model relates to the technical field of woven bag detection equipment, in particular to a woven bag surface defect marking device. Background Art

[0002] Visual inspection uses machines to replace the human eye for measurement and judgment. Machine vision inspection is characterized by increased production flexibility and automation. Machine vision is often used to replace human vision in hazardous working environments unsuitable for manual labor or where human vision is insufficient. Furthermore, in large-scale industrial production, human vision inspections are inefficient and lack high accuracy. Machine vision can significantly improve production efficiency and automation. Furthermore, machine vision facilitates information integration, making it a fundamental technology for computer-integrated manufacturing.

[0003] Currently, due to the increase in production speed in woven bag production, manual inspection can no longer meet the production quality control requirements. Machine vision inspection can accurately select woven bags with surface defects. However, current visual inspection equipment directly rejects unqualified woven bags based on the inspection results without making specific distinctions or markings. This results in all kinds of woven bags with different defects being mixed together. Later, it is necessary to identify the defect types of unqualified woven bags and summarize them for improvement. This requires human re-inspection and classification, increasing workload and reducing efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a woven bag surface defect marking device to solve the problem that existing visual inspection equipment does not make distinctions or marks and directly rejects unqualified woven bags, requiring personnel to re-inspect and classify, increasing workload and reducing efficiency.

[0007] The marking mechanism includes a first cylinder, a material storage barrel and a dipping wheel. The material storage barrel is rotatably mounted on the arc-shaped material guide plate. The two ends of the first cylinder are hinged to the arc-shaped material guide plate and the material storage barrel respectively. The dipping wheel is rotatably mounted on the bottom of the material storage barrel and is adapted to the material outlet of the material storage barrel.

[0008] The visual inspection camera, the main belt conveyor and the first cylinder work in coordination through a PLC controller.

[0009] A further technical solution is that a sponge block is installed on the discharge port of the storage barrel to abut against the dyeing wheel.

[0010] A further technical solution is that a liquid injection port is provided on the top of the storage barrel.

[0011] A further technical solution is: an arc-shaped flap is rotatably installed on the discharge end of the arc-shaped guide plate, the arc-shaped flap is hinged to one end of the second cylinder, the other end of the second cylinder is hinged to an external fixed base, and the second cylinder works in coordination through a PLC controller.

[0012] A further technical solution is: a transition plate is obliquely provided below the arc-shaped material guide plate.

[0013] A further technical solution is that a secondary belt conveyor is provided below the arc-shaped material guide plate.

[0014] A further technical solution is that the colors of the pigments in the storage barrels of the multiple marking mechanisms are different.

[0015] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0016] The utility model proposes a surface defect marking device for woven bags, which can mark the woven bags after being inspected by visual inspection equipment through multiple marking mechanisms, so as to facilitate the subsequent classification and summary by the staff, and obtain the number of corresponding defects as a reference and basis for adjusting the working parameters of the woven bag processing equipment.

[0028] Example 1:

[0029] This embodiment Figure 1 、 Figure 2 and Figure 3 As shown, a woven bag surface defect marking device includes a visual inspection camera 1, a main belt conveyor 2 is provided below the visual inspection camera 1, an arc-shaped guide plate 3 is provided at the tail of the main belt conveyor 2, and a plurality of marking mechanisms 5 are provided on the arc-shaped guide plate 3 toward the woven bag 4; wherein,

[0030] The marking mechanism 5 includes a first cylinder 6, a material storage barrel 7, and a dipping wheel 8. The material storage barrel 7 is rotatably mounted on the arc-shaped material guide plate 3. The two ends of the first cylinder 6 are hinged to the arc-shaped material guide plate 3 and the material storage barrel 7 respectively. The dipping wheel 8 is rotatably mounted on the bottom of the material storage barrel 7 and is adapted to the material outlet of the material storage barrel 7.

[0031] The visual inspection camera 1, the main belt conveyor 2 and the first cylinder 6 work in coordination through the PLC controller.

[0032] The visual inspection camera 1 is electrically connected to the visual inspection equipment. When the main belt conveyor 2 transfers the woven bag 4 to the bottom of the visual inspection camera 1, the visual inspection camera 1 starts working and controls the operation of the marking mechanism 5 under the control of the PLC controller. If there is no defect or the defect is not obvious, the marking mechanism 5 is in the initial state, and the dyeing wheel 8 does not contact the woven bag 4. When a defect exists, the first cylinder 6 contracts, the storage barrel 7 gradually becomes vertical, and the dyeing wheel 8 contacts the woven bag 4. As the main belt conveyor 2 transfers the woven bag 4, the dyeing wheel 8 leaves a mark on the woven bag 4 and makes a corresponding mark. When the woven bag 4 continues to move forward, it is turned over under the action of the arc-shaped guide plate 3. The unmarked woven bag 4 can return to the visual inspection camera 1 for the second side inspection. The marked woven bag 4 is manually judged whether to perform the second side inspection according to specific needs.

[0033] Preferably, a sponge block 9 is installed on the discharge port of the storage barrel 7 to abut against the dyeing wheel 8.

[0034] The sponge block 9 should be selected to have a larger density to prevent the storage barrel 7 from discharging the material too quickly.

[0035] Preferably, a liquid injection port 10 is provided on the top of the storage barrel 7 .

[0036] It is convenient for workers to add liquid into the storage barrel 7 through the liquid injection port 10.

[0037] Example 2:

[0038] Based on the above embodiments, this embodiment Figure 4 It is shown that an arc-shaped flap 11 is rotatably installed on the discharge end of the arc-shaped guide plate 3, the arc-shaped flap 11 is hinged to one end of the second cylinder 12, and the other end of the second cylinder 12 is hinged to an external fixed foundation. The second cylinder 12 coordinates its work through a PLC controller.

[0039] After the woven bag 4 is marked, under the control of the PLC controller, the second cylinder 12 contracts and the arc-shaped flap 11 flips outward, away from the main belt conveyor 2, so as to facilitate the removal of the marked woven bag 4.

[0040] Preferably, a transition plate 13 is obliquely provided below the arc-shaped material guide plate 3 .

[0041] The transition plate 13 is used for transitioning the woven bags 4 after they are removed.

[0042] Preferably, a secondary belt conveyor 14 is provided below the arc-shaped material guide plate 3 .

[0043] The auxiliary belt conveyor 14 is used to return the unmarked woven bag 4 for second side inspection;

[0044] The woven bags after being inspected on both sides can also be transferred by the secondary belt conveyor 14 to facilitate workers to collect and pack them.

[0045] Preferably, the colors of the pigments in the storage cartridges 7 of the multiple marking mechanisms 5 are different.

[0046] Different colored marks can be made on the woven bag 4. Different colored marks mean different defects, which is convenient for later personnel to classify and count.

[0047] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
