[0057] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0058] Please refer to Figures 1-3 The present application provides the following technical solutions:

[0059] A packaging device comprises a conveying unit 1, a feeding unit 2, a packaging unit 3 and a labeling unit 4. The conveying unit 1 can carry products to be packaged and push the products. The conveying unit 1 is provided with an identification assembly 11 capable of identifying the size of the products. The identification assembly 11 can be a visual size identification system. The feeding unit 2 is arranged on the discharge side of the conveying unit 1. The feeding unit 2 can supply workpieces for packaging corresponding to the products according to the feedback of the identification assembly 11. The feeding unit 2 comprises a plurality of storage boxes 21, which contain workpieces for packaging of different specifications. The packaging unit 3 is arranged on the discharge side of the conveying unit 1. The packaging unit 3 is provided with a bearing part 31 for placing the products to be packaged and the workpieces for packaging. The bearing part 31 is provided with packaging assemblies on both sides for packaging the products. The labeling unit 4 is arranged on the side of the packaging unit 3 away from the conveying unit 1, and is used for labeling the packaged products.

[0060] By means of the device, the size of the product is first judged by the visual size recognition system, so that the packaging paper matched with the current product can be selected, then the packaging unit 3 successively receives the packaging paper and the product, the folding of the two sides of the packaging paper is completed under the action of the packaging assembly, and finally the label is attached to the outside of the packaging paper by the labeling unit 4, so that the packaging is completed. The device realizes the automatic packaging function without manual attendance, can greatly reduce the burden of the staff, and reduces the possibility of operation errors in the packaging process.

[0061] On the basis of the above-mentioned embodiment, the conveying unit 1 further comprises a conveying assembly 12, and the conveying assembly 12 is a conveying belt type feeding structure. An identification assembly support 13 is arranged on both sides of the conveying assembly 12, and the identification assembly support 13 is used for supporting the identification assembly 11 and allowing the identification assembly 11 to be located above the conveying assembly 12; and the collection end of the identification assembly 11 is vertically or obliquely directed to the conveying assembly 12. In view of the adaptability to different identification assemblies 11, the identification assembly support 13 is arranged, and different identification assemblies 11 can obtain a good image collection distance by adjusting the height of the identification assembly support 13.

[0062] On the basis of the above-mentioned embodiment, the feeding unit 2 further comprises a feeding support 22, and the feeding support 22 comprises a side support part and a transverse support part, and the side support part and the transverse support part form a “door” shaped structure. The side support part is symmetrically provided with two side support parts, and the side support part is an electric telescopic rod or a pneumatic cylinder; and the transverse support part is arranged between the two side support parts.

[0063] The transverse support part comprises a rotating shaft 221 and a rotating frame 222. The rotating shaft 221 is rotatably connected to one side support part at both ends; the rotating frame 222 is fixedly connected to the rotating shaft 221 at the central axis of the frame body, and the rotating frame 222 comprises a plurality of frame rods 2221, the frame rods 2221 are arranged around the rotating shaft 222, and the axis of the frame rod 2221 is parallel to the axis of the rotating shaft 221; the number of the frame rods 2221 corresponds to the corresponding number of the storage boxes 21, and one storage box 21 is hung on each frame rod 2221. The rotating frame 222 is linked with the storage box driving member and can be rotated under the driving of the storage box driving member. The storage box 21 is in a natural state of hanging on the rotating frame 222.

[0064] Because the size of the storage box 21 will be different due to the different sizes of the packaging paper, the distance between the storage box 21 and the packaging unit 3 needs to be considered when the packaging paper is output. There are two solutions here, one is to use the structure of the present application, to set the feeding support 22 in an extendable form, so that the storage box 21 of different specifications can be in contact with the packaging unit 3 at a suitable distance. The other method is to improve the rotating frame 222, so that the distance between the frame rod 2221 of the rotating frame itself and the rotating shaft 221 is different, so that the distance between the different storage boxes 21 and the packaging unit 3 can also be adapted. However, in the case of the second way, if the size of a certain storage box 21 is changed, the structure of the rotating frame 222 itself needs to be adjusted, which is relatively inconvenient.

[0065] On the basis of the above-mentioned embodiment, the packaging unit 3 further comprises a moving part 32 connected with the bearing part 31, which can drive the bearing part 31 to move back and forth between the conveying unit 1 and the labeling unit 4; when the bearing part 31 moves towards the conveying unit 1, it passes below the feeding unit 2.

[0066] The side bottom of the storage box 21 is provided with a discharging groove, which is a through groove opened in the bottom of the storage box 21, and the packaging paper inside the storage box 21 can be discharged through the discharging groove. The bottom of the storage box 21 is also provided with a plurality of air holes to avoid the negative pressure of the bottom affecting the discharge of the packaging paper.

[0067] The bearing part 31 of the packaging unit 3 is provided with a plurality of air suction holes 311 connected with a vacuum pump through a pipeline, and by means of the vacuum suction force, when the bearing part 31 passes below the feeding unit 2, its upper side surface contacts the bottom surface of the storage box 21, the packaging paper inside the storage box 21 can be sucked out from the discharging groove, and the packaging paper is attached to the upper surface of the bearing part 31.

[0068] On the basis of the above-mentioned embodiment, a paper rubbing wheel is further arranged in the inner bottom of each storage box 21, and the paper rubbing wheel is arranged near the discharging groove. Each storage box 21 is provided with a driving motor corresponding to the paper rubbing wheel, and a sensor such as an infrared sensor or a laser sensor is arranged at the lower part of the storage box 21. When the sensor senses that the bearing part 31 passes below it, the paper rubbing wheel rotates to push the bottommost packaging paper out a distance, thereby facilitating the adsorption of the bearing part 31.

[0069] On the basis of the above-mentioned embodiment, referring to Figure 4The scheme also provides a rack 100, and all structural components are arranged on the rack 100. The rack 100 is provided with universal wheels at the bottom, and the movable rack 100 can make the whole device work in different environments. The moving part 32 comprises a guide frame 321 arranged between the conveying unit 1 and the labeling unit 4. The bearing part 31 can move back and forth on the guide frame 321.

[0070] The guide frame 321 comprises two guide rods arranged in parallel with the feeding direction of the conveying unit 1. The bearing part 31 is in sliding connection with the guide rods. The two ends of the guide frame 321 are respectively provided with traction motors connected with the bearing part 31 through cables. Through the rotation of the traction motors, the bearing part 31 is pulled to move between the conveying unit 1 and the labeling unit 4.

[0071] On the basis of the above-mentioned embodiment, the side of the guide frame 321 close to the conveying unit 1 is hinged to the rack 100, and a lifting cylinder 322 is arranged between the lower side of the guide frame 321 and the rack 100. The two ends of the lifting cylinder 322 are respectively in rotational connection with the rack 100 and the guide frame 321. Through the extension and contraction of the lifting cylinder 322, the guide frame 321 can be tilted and lifted as a whole, and the lifting end is the end of the guide frame 321 facing the labeling unit 4.

[0072] Because it is considered that the bearing part 31 may be difficult to suck out the wrapping paper inside the storage box 21 in a simple translational contact posture, and the paper at the bottom is not easy to be pushed out by the paper rolling wheel. Therefore, the guide frame 321 structure which can be lifted and tilted at one end is arranged. When the bearing part 31 moves towards the conveying unit 1, the lifting cylinder 322 is elongated to lift the guide frame 321, and the bearing part 31 translates while the storage box 21 rotates. When the two contact, the bearing part 31 tilts the box body of the storage box 21. At this time, the direction of the box mouth slightly faces the conveying unit 1, and the direction of the box bottom slightly faces the labeling unit 4. The internal wrapping paper is tilted as a whole towards the direction of the piece arranging groove, so it is easier to make the paper rolling wheel roll the wrapping paper.

[0073] On the basis of the above-mentioned embodiment, referring to Figure 5 , the inside of the storage box 21 is provided with an inner frame 211 which is a rectangular frame for placing wrapping paper. An exit is arranged on the frame corresponding to the direction of the piece arranging groove. The two sides of the corner part close to the piece arranging groove of the inner frame 211 are provided with inner frame rotating shafts which are in rotational connection with the inner wall of the storage box 21. The side of the inner frame 211 away from the inner frame rotating shafts is provided with a push plate 2111 at the bottom, and a through hole is arranged on the bottom of the storage box 21 corresponding to the push plate 2111. The bottom of the inner frame 211 is provided with an opening corresponding to the paper rolling wheel.

[0074] In use, the stacked wrapping paper of the inner frame 211 is placed inside, the moving frame 321 is tilted, when the bearing part 31 contacts the storage box 21, the push plate 2111 is pushed up from the lower side, so that the inner frame 211 is tilted, and under the double tilting of the storage box 21 and the inner frame 211, the wrapping paper inside can be tilted to the side of the conveying unit 1 with a larger inclination. So that the paper winding wheel can more easily wind the wrapping paper at the bottom.

[0075] Unlike the foregoing embodiments, the triggering action of the inner frame 211 can also be used as a signal to trigger the movement of the paper winding wheel drive motor, such as setting a touch switch or a proximity switch at the bottom of the push plate 2111. Compared with the foregoing scheme of activating the rotation of the paper winding wheel by an infrared or laser sensor, this way can better control the start and stop timing of the paper winding wheel drive.

[0076] On the basis of the foregoing embodiments, the wrapping unit 3 is provided with a first folding assembly 33 and a second folding assembly 34. The first folding assembly 33 is arranged on one side of the bearing part 31; one end of the first folding assembly 33 serves as a rotating end, and the other end extends upward above the bearing part 31; the second folding assembly 34 is arranged opposite to the first folding assembly 33 and on the other side of the bearing part 31; one end of the second folding assembly 34 serves as a rotating end, and the other end extends upward above the bearing part 31; one folding motor is arranged corresponding to each of the first folding assembly 33 and the second folding assembly 34, and the folding motor can drive the first folding assembly 33 and the second folding assembly 34 to rotate.

[0077] The first folding assembly 33 specifically includes a first folding rod, one end of the first folding rod being rotatably connected to one side of the bearing part 31. The second folding assembly 34 specifically includes two second folding rods, one end of each of the second folding rods being rotatably connected to the other side of the bearing part 31; the projection extension line of the first folding rod on the bearing part 31 is located between the projection extension lines of the two second folding rods on the bearing part 31; the first folding rod and the second folding rod are both arc-shaped rod bodies, and the concave side of each of them faces the bearing part 31.

[0078] After the wrapping paper and the product to be wrapped are placed on the bearing part 31, the two sides of the wrapping paper extend to the first folding assembly 33 and the second folding assembly 34 respectively, and the first folding assembly 33 and the second folding assembly 34 are rotated in turn to press the two sides of the wrapping paper on the product. In the specific implementation of this action, the second folding assembly 34 can be triggered first to press one side of the wrapping paper on the product, and then the first folding assembly 33 is pressed at the same time, and the second folding assembly 34 is reset. Because the first folding rod of the first folding assembly 33 is located between the two second folding rods, the reset of the second folding assembly 34 will not affect the first folding rod, only the two corners of the wrapping paper will be slightly lifted, and the wrapping paper will return to its original position when the second folding assembly 34 moves away from above the product. Then the subsequent labeling execution action can be performed.

[0079] On the basis of the above-mentioned embodiments, the packaging unit 3 further comprises a first sensing member 35 and a second sensing member 36, the first sensing member 35 is arranged on the carrying part 31 near the side close to the conveying unit 1, and is used for feeding back the product entering the carrying part 31. The second sensing member 36 is arranged on the carrying part 31 near the side close to the labeling unit 4, and is used for feeding back the product entering the packable position. Through the feedback of the two sensing members, the action execution time of the aforementioned first folding assembly 33 and the second folding assembly 34 can be controlled.

[0080] On the basis of the above-mentioned embodiments, a lower recessed area is formed in the middle of the carrying part 31, and a product placing plate is arranged in the lower recessed area. The aforementioned suction holes 311 are formed on the product placing plate, and the suction holes 311 are connected with the pump through a pipeline. The first folding rod and the second folding rod are respectively arranged on both sides of the product placing plate. The product placing plate is provided with a plurality of suction holes 311 in the middle position, and is provided with a plurality of suction holes 311 on the side facing the conveying unit 1. The distribution form of the suction holes 311 needs to meet the requirement of matching different sizes of packaging paper.

[0081] On the basis of the above-mentioned embodiments, a slope is arranged on both sides of the product placing plate corresponding to the first folding rod and the second folding rod, and the extension direction of the slope is downwardly extending towards both sides of the product placing plate. Considering the actual displacement of the first folding rod and the second folding rod, the slope can make the first folding rod and the second folding rod better press on the side edges of the product.

[0082] On the basis of the above-mentioned embodiments, the labeling unit 4 comprises a labeling frame 41, the labeling frame 41 is used for carrying the components of the labeling unit 4, and comprises a frame rod and a frame plate. The frame rod is arranged on both sides of the frame plate, and the frame plate is provided with a unwinding disc 42, a first winding disc 43, a second winding disc 44, a guide roller group 45 and a labeling member 46.
