Description

Technical Field

[0001] The present application relates to the technical field of fruit labeling, and in particular to a fruit labeling tray which is convenient for replacing labeling paper. Background Art

[0002] Fruits are an indispensable part of our daily diet. They not only provide a rich taste and flavor, but also contain a variety of nutrients that are essential to human health. For example, citrus fruits (oranges, grapefruits, lemons), strawberries, kiwis, etc. are rich in vitamin C; yellow and orange fruits such as papaya, mango, and cantaloupe are rich in beta-carotene, which plays an important role in maintaining vision, skin health, and the immune system. Some fruits are also rich in minerals (potassium, magnesium, calcium) and dietary fiber. Therefore, fruits are extremely rich in nutritional value and are one of the indispensable foods for maintaining human health.

[0003] At present, after fruits are picked and ripe, they can be packaged and transported to increase exports, thereby increasing the economic income of growers. In order to enable consumers to obtain the necessary information of each fruit (such as name, origin, etc.) in a timely and accurate manner, fruits are usually labeled before packaging. Currently, automatic labeling machines are used for continuous labeling, which can improve the efficiency of labeling operations.

[0004] The fruit labeling machine includes a conveyor belt for conveying fruits and a fruit labeling plate on the conveyor belt. Figure 1 As shown, the upper and lower parts are detachable. The upper part is provided with a label opening plate, a guide wheel and a paper reel for assembling a coiled label paper, and a sensor for positioning the label on the label paper. The lower part is provided with a labeling head with multiple rubber suction heads. The labeling operation is as follows: the coiled finished label paper is assembled on the label opening plate, and is guided by multiple guide wheels and then wound on the paper reel. The label paper passes through the sensor at the same time, and the position of the label on the label paper is detected by the sensor. When labeling, the fruit is continuously conveyed from the bottom of the labeling plate through the conveyor belt, and the labeling head rotates intermittently. Each rubber head can absorb each label on the moving label paper by negative pressure, and then each label is blown on the surface of the fruit by air pressure during the rotation process to realize the labeling operation (there is glue on the label paper, which can be adhered to the surface of the fruit). The function of the sensor is to detect the traction distance of the paper reel to the labeling plate. When the label paper is detected, the paper reel stops traction so that the label paper can correspond to each rubber head to avoid the occurrence of deviation.

[0005] When the labels on the finished label paper are used up, the finished label paper needs to be replaced. Usually, the upper half of the labeling tray needs to be disassembled to replace the label paper and remove the waste label paper. Figure 2 During the process, the sensor wire will be pulled, which will cause poor contact or breakage of the wire ( Figure 3As shown in the figure, after installing a new label paper in the later stage, poor contact of the sensor will affect the deviation of the label paper from the rubber suction head, resulting in problems such as insecure pasting and label peeling after pasting on the fruit. At the same time, the replacement cycle of the broken guide is relatively long, which will greatly affect the continuous labeling efficiency during the frequent operation of replacing the label paper. Summary of the Invention

[0006] In view of the above problems, the present application aims to provide a fruit labeling tray that facilitates the replacement of the label paper. When the finished label paper is frequently replaced, disassembling the upper half will not cause a linkage effect on the sensor, and effectively protect the wire connection of the sensor, thereby ensuring the positioning accuracy of the label on the label paper by the sensor, reducing the failure rate, and improving the labeling efficiency.

[0007] To achieve the above object, the technical solution adopted by the present application is as follows: A fruit labeling tray that facilitates the replacement of the label paper, the labeling tray is composed of a detachable upper half and a lower half. The upper half is provided with an opening tray for assembling the roll-shaped label paper, and a sensor for positioning the label on the label paper. The lower half is provided with a labeling head having a plurality of rubber suction heads. It is characterized in that: the sensor is arranged and connected to the lower half, and a protective mechanism for guiding the positioning and assembly of the upper half and the lower half is arranged outside the sensor.

[0008] Preferably, an embedding groove is opened at a position corresponding to the sensor on the upper half.

[0009] Preferably, the protective mechanism is a U-shaped protective plate arranged around the sensor, and the surface of the U-shaped protective plate is a groove structure embedded in the upper half.

[0010] Preferably, the top end of the U-shaped protective plate is set as an arc structure.

[0011] The beneficial effect of the present application is: The sensor is arranged and connected to the lower half. When replacing the label paper, disassembling the upper half will not cause a linkage effect on the sensor, and effectively protect the wire connection of the sensor, thereby ensuring the positioning accuracy of the label on the label paper by the sensor, reducing the failure rate, and improving the labeling efficiency.

[0012] The arranged protective mechanism can effectively protect the sensor, and at the same time realize the guiding function of the upper half relative to the lower half, thereby shortening the assembly time of the upper half after replacing the label paper. Brief Description of the Drawings

[0025] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Referring to Figures 1-11 A fruit labeling tray that is convenient for replacing label paper as shown. The labeling tray 1 has a detachable upper half 11 and a lower half 12. The upper half 11 is provided with a label opening tray 3 for assembling a roll of label paper 2, and a sensor 4 for positioning the label 21 on the label paper 2. The lower half 12 is provided with a labeling head 5 having a plurality of rubber suction heads 51. Currently, after assembling a new roll of label paper onto the label opening tray 3, the label paper can be automatically sucked by the rubber suction heads 51 and pasted onto the fruit to achieve continuous labeling operation.

[0027] In order to solve the problem that the wire contact of the sensor 4 is poor and breaks during the frequent replacement of label paper operation, which affects the labeling quality and efficiency, as Figures 4-5As shown, the sensor 4 is arranged and connected to the lower half 12. Thus, when replacing the label paper, after disassembling the upper half, it will not cause a linkage effect on the sensor 4, effectively protecting the wire connection of the sensor 4. Thereby, it can ensure the positioning accuracy of the label on the label paper, reduce the failure rate, and improve the labeling efficiency.

[0028] After the sensor 4 is arranged on the lower half 12, frequent assembly of the upper half 11 will be in contact with the sensor 4, thereby causing the sensor 4 to be impacted and tilted (as Figure 6 shown), thus causing the problem of label positioning skew again. Therefore, to effectively protect the sensor 4, as Figure 7 shown, a protection mechanism for guiding the positioning and assembly of the upper half 11 and the lower half 12 is arranged outside the sensor 4. On the basis of effectively protecting the sensor 4, this protection mechanism can also realize the guiding function of the upper half 11 relative to the lower half 12, thereby shortening the assembly time of the upper half 11 after replacing the label paper.

[0029] Specifically, as Figure 5 shown, an embedding groove 1a is opened at a position corresponding to the sensor 4 on the upper half 11, and preferably, a bracket 9 for assembling the sensor 4 is fixed on the lower half 12. The sensor 4 can be fixed on the lower half 12 through this bracket. When replacing the label paper, the upper half 11 and the lower half 12 are disassembled (preferably bolt-connected). After replacing the label paper and assembling the upper half 11, the sensor 4 fixed on the lower half 12 is embedded in the embedding groove 1a of the upper half 11, realizing the rapid assembly of the upper half 11 and the lower half 12 and solving the influence on the wire connection of the sensor 4.

[0030] To achieve the protection effect on the sensor 4 during the above assembly process, as Figures 7-10 shown, the protection mechanism is a U-shaped protection plate 6 arranged around the sensor 4 (this U-shaped protection plate 6 is preferably fixed on the bracket 9). The U-shaped protection plate 6 wraps the sensor from the periphery to achieve protection, as Figure 8 shown, thereby avoiding the contact and impact on the sensor 4 when assembling the upper half 11, and thus effectively protecting the sensor 4.

[0031] To facilitate the rapid positioning and assembly of the upper half 11 and the lower half 12, as Figure 9 shown, the surface of the U-shaped protection plate 6 is set as a groove structure for embedding the upper half 11. When assembling the upper half 11, the side of the embedding groove 1a is embedded in the groove structure of the U-shaped protection plate 6, as Figure 10As shown, the upper half 11 and the lower half 12 are in the same plane. Then, continue to move the upper half 11 downward along the groove structure so that the bottom end face of the upper half 11 is in positive contact with the upper end face of the lower half 12. Then, through bolt connection, rapid matching can be achieved. Therefore, through the groove structure of the U-shaped protection plate 6, the assembly guidance of the upper half 11 can be quickly realized, and the alignment connection with the lower half 12 can be completed.

[0032] Since the overall area of the labeling disc 1 is relatively large, both hands are needed to support both sides of the upper half 11 during assembly. Usually, the gap between the embedding groove 1a of the upper half 11 and the groove structure of the U-shaped protection plate 6 is reserved to be relatively small. Therefore, to facilitate the embedding groove 1a of the upper half 11 to be further smoothly embedded into the groove structure of the U-shaped protection plate 6, as Figures 8-9 shown, the top end of the U-shaped protection plate 6 is set as an arc structure. This arc structure makes the width of the groove structure at the top end of the U-shaped protection plate 6 smaller than the horizontal width of the embedding groove 1a, facilitating the embedding groove 1a to be smoothly sleeved in the groove structure of the U-shaped protection plate 6. Thus, during the process of manually supporting the upper half 11, it is convenient for its corresponding assembly with the lower half.

[0033] The principle of this application is: The sensor 4 on the fruit labeling disc 1 is arranged on its lower half. When replacing the finished label paper of the upper half, the linkage influence on the sensor 4 and the wire can be avoided, thereby effectively protecting the sensor 4 and avoiding problems such as label deviation and insecure sticking on the fruit. And the set U-shaped protection plate 6 can play a guiding role for the upper half 11 after replacing the label paper, facilitating the rapid assembly of the upper half and the lower half, and at the same time playing an effective protective role for the sensor.

[0034] The above shows and describes the basic principle, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will have various changes and improvements, and these changes and improvements all fall within the scope of this application claimed.
