Description

Technical Field

[0001] The present invention relates to the technical field of packaging and conveying equipment, and more specifically, to a dental floss packaging and conveying device with a thread breakage detection function. Background Art

[0002] Dental floss sticks, also known as dental floss picks, are a product used with a toothbrush in daily oral care. Before dental floss sticks, people used dental floss to achieve the same effect. Compared with dental floss, dental floss sticks are more convenient, efficient, safe, and hygienic. In the sale of dental floss sticks, several dental floss sticks are placed in a box and sold as a whole box.

[0003] In the prior art, for example, the invention patent with application number CN201811510115.X discloses a fully automatic boxing device for dental floss sticks, including a rack loading and conveying device, a detection and feeding mechanism for realizing dental floss stick quantity detection and automatic replenishment, a first rack transfer mechanism for grabbing a rack from the rack loading and conveying device to the detection and feeding mechanism, a full material temporary storage and conveying device docked with the detection and feeding mechanism, a second rack transfer mechanism for grabbing a rack in the full material temporary storage and conveying device to a boxing station, and a boxing mechanism for grabbing a quota number of dental floss sticks for boxing.

[0058] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0059] Embodiment 1:

[0060] like Figure 1As shown, the present invention provides a dental floss packaging and conveying device with a thread breakage detection function, comprising:

[0061] A conveying mechanism 1, wherein the top of the conveying mechanism 1 is provided with a rigid conveying plane 2;

[0062] A carrying platform 3, the carrying platform 3 is connected to the conveying plane 2, and a dental floss stick 4 is placed on the carrying platform 3;

[0063] The image acquisition unit is disposed on the carrier platform 3 and is used to acquire images of the dental floss sticks 4 on the carrier platform 3. The controller obtains the number and the break position of the dental floss sticks 4 based on the image information analysis.

[0064] The working principle and beneficial effects of the above technical solution are:

[0066] Through the above-mentioned structural design, a dental floss packaging and conveying device with a breakage detection function is provided, an image acquisition unit is arranged on the conveying device, and the dental floss sticks 4 on the conveying mechanism 1 are detected by the image acquisition unit, and the number and breakage of the dental floss sticks 4 are analyzed online, thereby improving the integration of the conveying device of the dental floss sticks 4, ensuring that the number of dental floss sticks 4 taken out during packaging meets the requirements, facilitating the removal and replenishment of broken dental floss sticks 4, reducing the breakage rate of the dental floss sticks 4, and thus ensuring the quality of the finished dental floss product.

[0067] Embodiment 2:

[0068] like Figure 2 , 3 As shown, on the basis of the above-mentioned embodiment 1, a plurality of groups of dental floss support rod assemblies are arranged in parallel on the supporting platform 3, and the dental floss support rod assemblies include: a head support rod 5 and a tail support rod 6, the head of the dental floss stick 4 is sleeved on the head support rod 5, the tail of the dental floss stick 4 is clamped between the two tail support rods 6, and the dental floss of the dental floss stick 4 is located on one side of the head support rod 5; the dental floss sticks 4 are placed on the supporting platform 3 to form a multi-group and multi-layer stacking form, and each time a group of dental floss sticks 4 are taken out from one side for packaging.

[0069] The working principle and beneficial effects of the above technical solution are:

[0070] The dental floss stick 4 is placed on the carrier 3. The multiple groups of dental floss support rod assemblies provided on the carrier 3 are arranged at equal intervals on the carrier 3 to form multiple groups of dental floss sticks 4 arrays. On a single group of dental floss support rod assemblies, multiple dental floss sticks 4 are placed in sequence from bottom to top to form a multi-layer dental floss stick 4 array, thereby forming a multi-group multi-layer stacking form. When packaging, a group of dental floss sticks 4 can be taken out from the same side for packaging each time. The dental floss stick 4 includes a head, a middle part and a tail. The head forms a U-shaped structure for fixing the dental floss, the middle part is used for the user to hold, and the tail forms a curved structure. When the dental floss stick 4 is installed, the head of the dental floss stick 4 is put on the head support rod 5 and passed through the U-shaped space. After the multiple dental floss sticks 4 are arranged, the dental floss is located on the same side; the tail of the dental floss stick 4 is clamped between the two tail support rods 6; the stability of the dental floss stick 4 is maintained by the arrangement of the head support rod 5 and the tail support rod 6, so that the multiple dental floss sticks 4 can be neatly arranged, which is convenient for the subsequent removal of the dental floss sticks 4.

[0071] Embodiment 3:

[0072] On the basis of the above-mentioned embodiment 2, the image acquisition unit includes a first image acquisition device, which is arranged on the side of the carrier 3 and is used to obtain image data of one side of the dental floss in the dental floss stick 4;

[0073] The controller receives the image information for data analysis, including analysis of the number of dental floss sticks 4 and the position of broken dental floss. During the analysis, edge recognition is performed on the image to determine the number of dental floss in the analysis group and calculate the distance between adjacent dental floss. When the distance between adjacent dental floss exceeds a preset threshold, it indicates that the distance between adjacent dental floss is too large and there is a possibility of broken dental floss between adjacent dental floss.

[0074] The working principle and beneficial effects of the above technical solution are:

[0075] The image acquisition unit includes a first image acquisition device, which is arranged on the side of the carrier 3 where the dental floss is exposed, and can take the image of the dental floss stick 4 on the carrier 3 from the side. The controller processes the image and extracts the image of the dental floss in the image, and uses this as a basis for analysis to obtain the number of dental floss, and evaluates whether the number of dental floss sticks 4 is qualified; and identifies the position where the dental floss spacing is too large, where the dental floss may be broken and missing, that is, it can determine the layer where the broken dental floss stick 4 is located, which serves as the first basis for judging whether the dental floss is broken.

[0076] Embodiment 4:

[0077] On the basis of the above-mentioned embodiment 3, the image acquisition unit includes a second image acquisition device, which is arranged above the carrier 3 and is used to acquire image data above the dental floss stick 4;

[0078] The controller receives the image information and performs data analysis to determine the position of the offset dental floss stick 4. During the analysis, the image edge is identified and the deviation value of the dental floss stick 4 from the preset position is calculated. When the deviation value of the head of the dental floss stick 4 exceeds the preset threshold, it indicates that the head of the dental floss stick 4 is excessively deflected, and there is a possibility of broken dental floss in the group where the dental floss stick 4 is located.

[0079] The working principle and beneficial effects of the above technical solution are:

[0080] The image acquisition unit includes a second image acquisition device, which is arranged above the carrier 3 and can acquire the image of the dental floss stick 4 on the carrier 3 from above. After image processing, the controller extracts the image of the dental floss stick 4 in the image and determines whether the dental floss stick 4 is in the preset position. When only the head of the dental floss stick 4 is excessively deflected, it indicates that the head of the dental floss stick 4 fails to fit on the head support rod 5. Here, the dental floss stick 4 may be broken, that is, the group where the broken dental floss stick 4 is located can be determined, which is used as the second basis for judging the broken dental floss. Combined with the first basis for judging, the specific position of the broken dental floss stick 4 is further determined. Through the above structural design, a dual image acquisition unit is used to respectively shoot the top surface and the side surface of the dental floss stick 4 on the carrier 3, and the image data of the two are combined to analyze the specific position of the broken dental floss stick 4, and the dental floss stick 4 is sorted and supplemented according to this position, which greatly reduces the inspection time of the staff.

[0081] Embodiment 5:

[0082] like Figure 1 As shown, on the basis of the above-mentioned embodiment 1, a U-shaped carrying frame 7 is connected to the bottom of the carrying platform 3, one side of the bottom end of the carrying frame 7 is rotatably connected to the conveying plane 2, and the other side of the bottom end of the carrying frame 7 is connected to a guide rod 8, and a guide plate 9 is provided on the conveying plane 2, and an arc groove is provided on the guide plate 9, and the center of the arc groove is coaxially arranged with the rotation center of the carrying frame 7, and the guide rod 8 is slidably connected in the arc groove.

[0083] The working principle and beneficial effects of the above technical solution are:

[0084] The U-shaped carrier frame 7 is installed at the bottom of the carrier platform 3, which is convenient for connecting the carrier platform 3 and the conveying plane 2; one end of the carrier frame 7 is rotatably connected to the conveying plane 2, and can drive the carrier platform 3 to rotate synchronously; the guide rod 8 at the other end is slidably set in the arc groove of the guide plate 9, and the arc groove guides it to ensure the stability of the carrier platform 3 when rotating.

[0085] Embodiment 6:

[0086] like Figure 1 , 4 As shown in , 5, on the basis of the above embodiment 5, a dental floss tidying unit is provided on the conveying plane 2, and the dental floss tidying unit is used to drive the bearing platform 3 to rotate, and the dental floss tidying unit includes:

[0087] A support block 11, the support block 11 is connected to one side of the conveying plane 2 and is arranged close to the edge thereof;

A rack is arranged on the side of the horizontal drive rod 10, and the rack is meshed with the gear 13.

[0094] The working principle and beneficial effects of the above technical solution are:

[0095] When the dental floss stick 4 is transported, due to the U-shaped space formed at the head of the dental floss stick 4, the head of the dental floss stick 4 and the head support rod 5 can shake and deviate relative to each other, and the tail of the dental floss stick 4 and the tail support rod 6 can also shake and deviate relative to each other. When the offset is large, it affects the accuracy of the broken wire detection and the removal of the dental floss stick 4. Therefore, a dental floss tidying unit is set up. When in use, when the conveying mechanism 1 conveys the supporting platform 3 to a place close to the packaging station, it stops moving, and the gear 13 under the supporting platform 3 meshes with the rack on the side of the horizontal driving rod 10; at this time, the power equipment is started to drive the horizontal driving rod 10 to move forward, and the rack on the side of the horizontal driving rod 10 meshes with the gear 13 for transmission, driving the gear 13 to rotate, and the fan-shaped plate 14 on the gear 13 rotates synchronously, and the fan-shaped plate 14 drives the connecting rod 16 to rotate through the column 17, so that the upper sleeve 15 rotates above the lower rotating shaft 12, and the upper sleeve 15 drives the supporting frame 7 to rotate synchronously, so as to realize The supporting platform 3 is rotated forward; then, the power device is controlled to move in the reverse direction, driving the horizontal driving rod 10 to rotate in the reverse direction, and the supporting platform 3 rotates in the reverse direction accordingly; as the horizontal driving rod 10 reciprocates, the supporting platform 3 is rotated back and forth, causing the dental floss stick 4 on the supporting platform 3 to shake, and when the shaking stops, the head of the dental floss stick 4 is pressed against the head support rod 5 under the action of inertia, and the tail of the dental floss stick 4 is at the maximum bending position and pressed against the tail support rod 6 on one side, so that the dental floss stick 4 can be more regular to one side, reducing the position deviation caused by the stacking process of the dental floss stick 4, and facilitating the detection and removal of the dental floss stick 4.

[0096] Embodiment 7:

[0097] like Figure 4 , 5 As shown, based on the above-mentioned embodiment 6, a resilient driving component is provided on the fan-shaped plate 14, and the resilient driving component includes:

[0098] A fixing plate 18, wherein two fixing plates 18 are connected to the top of the sector plate 14 at intervals;

The sliding columns 20 are slidably connected with the fixed plates 18 . A spring is sleeved on the sliding columns 20 , and the spring is connected between the driving plates 19 and the fixed plates 18 .

[0100] The working principle and beneficial effects of the above technical solution are:

[0101] A fixing plate 18 is provided on the sector plate 14, and a driving plate 19 is connected to the fixing plate 18.

[0102] Embodiment 8:

[0103] like Figure 6-10 As shown, on the basis of the above-mentioned embodiment 7, a resonance unit is provided in the lower rotating shaft 12 and the upper sleeve 15, and the resonance unit includes:

[0104] Side sliding grooves 21, multiple side sliding grooves 21 are evenly arranged on the inner wall of the upper sleeve 15;

[0105] A vibration contact 22, the rod of the vibration contact 22 is slidably connected in the side slide groove 21, the end of the vibration contact 22 protrudes from the inner wall of the upper sleeve 15, and a spring is connected between the vibration contact 22 and the bottom of the side slide groove 21;

[0106] The vibration plate 23 is connected to the end surface of the rod portion of the vibration contact 22 and the bottom of the side sliding groove 21 .

[0107] The resonance unit further includes a resonance disk 24, which is connected to the lower shaft 12 and corresponds to the position of the vibration contact 22. The resonance disk 24 includes:

[0108] Lugs 25, the lugs 25 are evenly connected to the side wall of the resonance disk 24, the number of the lugs 25 is equal to the number of the vibration contacts 22, and the lugs 25 slide relative to the inner wall of the upper sleeve 15;
