[0042] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0043] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0044] In the production process of automobile parts, in order to prevent the precision of parts from being affected by humidity, dust, etc. in the environment, it is necessary to carry out bagging for such products. In the traditional production process, bagging relies on manual operation, which is not only inefficient, but also easy to cause product damage due to human negligence.

[0045] After in-depth research, the inventor found that currently there is an automated bagging device that uses automated bagging. The current automated bagging device uses multiple driving parts and multiple adsorption parts to achieve bag taking and bag opening. It is not only complex in structure, but also has high energy consumption, resulting in high production costs.

[0046] The bag taking mechanism 100 of the present application replaces the traditional first driving member with the elastic member 21 and the stopper 3, and also realizes the integration of the tensioning, bag taking and bag opening functions of the packaging bag, which greatly simplifies the structure of the equipment and reduces the manufacturing cost of the automated bagging device.

[0047] Example 1

[0048] like Figures 1 to 3 As shown, embodiment 1 of the present application provides a bag taking mechanism, comprising:

[0049] Rack 1;

[0050] The bag storage part 2 comprises an elastic member 21 and a carrying plate 22. The two sides of the elastic member 21 along the first direction A are respectively in contact with the frame 1 and the first surface of the carrying plate 22. The second surface of the carrying plate 22 opposite to the first surface is used for carrying the packaging bag.

[0051] The stopper 3 is disposed on the frame 1, the stopper 3 is spaced from and opposite to the second surface of the carrying plate 22, the stopper 3 can be in close contact with the edges of both sides of the packaging bag along the second direction B, the first direction A, the second direction B and the third direction C are perpendicular to each other, and the third direction C is consistent with the opening direction of the packaging bag;

[0052] A first driving unit 4 is arranged on the frame 1;

[0053] The adsorption part 5 is connected to the first driving part 4 . The adsorption part 5 is opposite to the second surface of the carrying plate 22 . The adsorption part 5 is used to adsorb part of the packaging bag. The first driving part 4 is used to drive the adsorption part 5 to reciprocate along the first direction A.

[0054] Specifically, the frame 1 is the supporting structure of the entire bag taking mechanism 100, and provides a stable installation foundation for other components. It ensures the stability of the bag taking mechanism 100 during operation. The specific structure of the frame 1 is not further limited and can be designed according to actual use requirements.

[0055] The bag storage part 2 is used to store and supply packaging bags in an orderly manner to ensure a continuous supply of packaging bags during continuous operation. The elastic member 21 of the bag storage part 2 is in a compressed state under normal working conditions. Under the action of its own restoring force, the elastic member 21 pushes the packaging bags on the supporting plate 22 to move along the first direction A to move closer to the adsorption part 5, so as to facilitate the adsorption of the adsorption part 5. One side of the elastic member 21 along the first direction A can be fixedly connected or in contact with the frame 1, and the other side of the elastic member 21 along the first direction A can be fixedly connected or in contact with the first surface of the supporting plate 22. The elastic member 21 can be made of a silicone pad. The supporting plate 22 can stably support a certain number of packaging bags to be taken. The second surface of the supporting plate 22 can be polished or treated with other appropriate anti-sticking and friction-reducing treatments to prevent the packaging bags from sticking or being damaged by friction.

[0056] The stopper 3 can not only limit the excessive movement of the packaging bag along the first direction A, but also work with the elastic member 21 to keep the packaging bag in a tensioned state. The stopper 3 can include two strip plates extending along the third direction C, the two strip plates are spaced and relatively arranged on the frame 1 along the second direction B, and each strip plate can be in close contact with the edge of one side of the packaging bag along the second direction B. In order to ensure the smoothness of the subsequent opening, the two strip plates can have a certain distance from the bag opening of the packaging bag. The contact surface between the two strip plates and the packaging bag can be smoothed, and the corners of the two strip plates can be rounded to avoid damaging the packaging bag.

[0057] The first driving part 4 is the power source in the bag taking mechanism 100, which is responsible for providing power to drive the adsorption part 5 to perform the bag taking operation. The first driving part 4 can be connected to the adsorption part 5 by bolts, clamping, etc. The first driving part 4 can be selected from a linear motor, a cylinder, a hydraulic cylinder, etc.

[0058] The adsorption part 5 is used to adsorb part of the first surface of a single packaging bag. The specific structure of the adsorption part 5 is known to those skilled in the art and will not be described in detail here.

[0059] Compared with the prior art, the bag taking mechanism 100 provided in Example 1 of the present application, by making the elastic member 21 abut against the frame 1 and the supporting plate 22 on both sides along the first direction A respectively, and utilizing the elastic force of the elastic member 21 to enable the packaging bag on the supporting plate 22 to move along the first direction A close to the adsorption portion 5, so that the packaging bag can always be adsorbed by the adsorption portion 5; the stopper 3 is in close contact with the edges of the packaging bag on both sides along the second direction B. On the one hand, the stopper 3 limits the excessive movement of the packaging bag along the first direction A, ensuring that the packaging bag is always in the preset area; on the other hand, the close contact of the stopper 3 cooperates with the elastic member 21 to keep the packaging bag in a moderate tension state, thereby enhancing the controllability of the bag taking process; the adsorption portion 5 can accurately adsorb part of the packaging bag under the drive of the first driving portion 4, thereby realizing the effective extraction of a single packaging bag; and, since the packaging bag has been kept in a tensioned state by the elastic member 21 and the stopper 3, the adsorption portion 5 can easily pull the bag mouth during the movement to make it open smoothly, thereby completing the bag opening action while taking the bag, thereby improving the overall operation efficiency.

[0060] The bag taking mechanism 100 of the present application replaces the traditional motor with the elastic member 21 and the stopper 3, and integrates the functions of tensioning, taking and opening the packaging bag, greatly simplifies the structure of the equipment, and reduces the manufacturing cost of the automated bagging device.

[0061] like Figure 1 and Figure 2 As shown, in some embodiments, the storage bag portion 2 includes:

[0062] The box body 23 is disposed on the frame 1 , and the elastic member 21 is disposed in the box body 23 and abuts against the bottom of the box body 23 . The side wall of the box body 23 is used to limit the movement of the packaging bag along the second direction B and the third direction C.

[0063] Specifically, a portion of the frame 1 may be penetrated to form a mounting hole along the first direction A, the side wall of the box body 23 may be bolted or clamped to the frame 1, and the opening of the box body 23 faces the adsorption portion 5. The carrying plate 22 and the packaging bag are both arranged in the box body 23, and the peripheral side of the packaging bag can contact the side wall of the box body 23 to limit the movement of the packaging bag along the second direction B and the third direction C. The size of the box body 23 can be designed according to the size of the packaging bag, and the shape of the box body 23 can be designed according to the shape of the packaging bag.

[0064] The box body 23 provides a stable storage space for the packaging bag, reducing the displacement and damage of the packaging bag during the storage process; the limiting function of the side wall of the box body 23 ensures that the packaging bag remains in the correct position during the bag taking process, so that the two side edges of the packaging bag along the second direction B can be closely contacted by the stop part 3.

[0065] In order to limit the position of packaging bags of different types and improve the adaptability of the bag storage part 2, as shown in FIG. Figure 1 and Figure 2 As shown, in some embodiments, the storage bag portion 2 further includes:

[0066] The movable plate 24 is disposed in the box body 23 and movably connected to the box body 23. The movable plate 24 and a part of the side wall of the box body 23 are used to jointly limit the movement of the packaging bag along the second direction B and / or the third direction C;

[0067] The first locking member 25 is connected to the movable plate 24 and the frame 1 respectively, and is used to limit the movement of the movable plate 24 .

[0068] Specifically, the movable plate 24 may include a first movable sub-plate 241 and a second movable sub-plate 242. When the movable plate 24 and a part of the side wall of the box body 23 are used to jointly limit the movement of the packaging bag along the second direction B: the first movable sub-plate 241 may be slidably connected with the box body 23 along the second direction B. For example, a first strip-shaped hole is provided on the two first side walls of the box body 23 opposite to each other along the third direction C. The first hole extends along the second direction B. The first movable sub-plate 241 is slidably connected with the two first side walls of the box body 23 along the second direction B through the strip-shaped hole. At this time, the first locking member 25 may be a locking bolt to ensure that the first movable sub-plate 241 is fixed at the set position. Or,

[0069] The first sub-movable plate 241 can be engaged with the bottom of the box body 23. When the first sub-movable plate 241 and part of the side wall of the box body 23 are used to jointly restrict the movement of the packaging bag along the second direction B, a plurality of slots can be arranged at intervals along the second direction B at the bottom of the box body 23, and the first sub-movable plate 241 is engaged with the bottom of the box body 23 through the slots. At this time, the slots form the first locking member 25.

[0070] There can be one or two first movable sub-plates 241. When there are two first movable sub-plates 241, the two first movable sub-plates 241 are spaced apart along the second direction B, and the elastic member 21 is located between the two first movable sub-plates 241. At this time, the two first movable sub-plates 241 can form two side walls of the box body 23 along the second direction B to simplify the overall structure.

[0071] When the movable plate 24 and part of the side wall of the box body 23 are used to jointly restrict the movement of the packaging bag along the third direction C, the second sub-movable plate 242 can be slidably connected with the bottom of the box body 23 along the third direction C, or the second sub-movable plate 242 can be snap-fitted with the bottom of the box body 23, and the specific connection method and the selection of the first locking member 25 can refer to the connection method of the first sub-movable plate 241 and the corresponding selection of the first locking member 25. The number of the second sub-movable plates 242 can also refer to the number of the above-mentioned movable plates 24.

[0072] The first movable sub-plate 241 and the second movable sub-plate 242 may be provided separately or in combination, and may be designed according to actual production requirements.

[0073] The movable plate 24 can flexibly adjust the limiting position of the packaging bag along the second direction B and / or the third direction C according to the specific model or size of the packaging bag through the movable connection with the box body 23 and the cooperation with the side wall, thereby significantly improving the adaptability of the bag storage part 2 to packaging bags of different models.

[0074] like Figure 1 and Figure 2 As shown, in some embodiments, the elastic member 21 includes:

[0075] The two ends of the spring are respectively in contact with the frame 1 and the first surface of the bearing plate 22 . The bearing plate 22 is slidably connected with the frame 1 along the first direction A.

[0076] Specifically, the bag storage part 2 may further include a guide column and a mounting seat, wherein the guide column is used to ensure the stability of the bearing plate 22 sliding along the first direction A. The first end of the guide column is fixedly connected to the first surface of the bearing plate 22, and the second end of the guide column is slidably connected to the mounting seat along the first direction A. The mounting seat may be connected to the base of the box body 23 by means of a snap connection or a bolt. The mounting seat facilitates the assembly of the bag storage part 2 and improves the convenience of the mechanism during the assembly process. The spring is sleeved on the guide column, one end of the spring is connected or in contact with the first surface of the bearing plate 22, and the other end of the spring is connected or in contact with the mounting seat.

[0077] The number of springs can be one or more. When the number of springs is more than one, the number of springs can be two, three, four or even more, and the multiple springs are arranged at intervals. The number of guide posts can be the same as the number of springs, and each spring is sleeved on a guide post.

[0078] like Figure 1 and Figure 3 As shown, in some embodiments, the stopper 3 includes:

[0079] Two groups of spring sheet groups 31 are arranged at intervals on the frame 1 along the second direction B. The two groups of spring sheet groups 31 are opposite to and spaced from the second surface of the carrying plate 22. Each group of spring sheet groups 31 can be in close contact with one side edge of the packaging bag along the second direction B.

[0080] Specifically, each group of spring sheet groups 31 can be composed of one or more spring sheets. When each group of spring sheet groups 31 includes multiple spring sheets, the multiple spring sheets can be arranged at intervals along the third direction C to form multi-point contact with the packaging bag along the second direction B, thereby enhancing the uniformity and stability of the limiting effect. The spring sheets are fixed on the frame 1, and some of the spring sheets are opposite to and spaced from the second surface of the bearing plate 22 to ensure that they can closely contact the edge of the packaging bag during operation, thereby providing an effective limiting effect. The shape of the spring sheet can be straight, arc-shaped, etc.

[0081] The spring group 31 restricts the packaging bag by means of flexible contact, thereby reducing scratches or squeeze damage to the edge of the packaging bag and protecting the quality of the packaging bag. Meanwhile, a good contact state also helps to maintain smoothness in the subsequent bag-taking process.

[0082] like Figure 1 and Figure 3 As shown, in some embodiments, the stopper 3 further includes:

[0083] The bag opening tongue 32 is arranged on the frame 1 on one side of the supporting plate 22 along the third direction C. The bag opening tongue 32 can have a preset distance with the packaging bag along the first direction A. The adsorption part 5 adsorbs part of the packaging bag to make the bag opening tongue 32 extend into the bag opening of the packaging bag.

[0084] In some embodiments, the stopper 3 further includes:

[0085] The jet assembly 33 is disposed on the bag opening tongue 32 and is used for jetting air into the packaging bag.

[0086] In some embodiments, the stopper 3 further includes:

[0087] The pressing plate 34 is arranged on the frame 1 on the other side of the supporting plate 22 along the third direction C. The pressing plate 34 can have a preset distance with the packaging bag along the first direction A. The adsorption part 5 adsorbs part of the packaging bag to make the pressing plate 34 contact with the bottom edge of the packaging bag.

[0088] Specifically, the pressure plate 34 may include a first sub-pressure plate 341 and a second sub-pressure plate 342. The first sub-pressure plate 341 and the second sub-pressure plate 342 are spaced apart along a third direction C and are relatively arranged on the frame 1. The first sub-pressure plate 341 can be opposite to the bag opening of the packaging bag along the third direction C, and the second sub-pressure plate 342 is close to the bottom of the packaging bag. The first sub-pressure plate 341 and the second sub-pressure plate 342 both have a preset distance from the packaging bag along the first direction A.

[0089] The first sub-pressing plate 341 can be fixedly connected to the frame 1, or the first sub-pressing plate 341 can be slidably connected to the frame 1 along the third direction C, and the first sub-pressing plate 341 can be fixed at a certain position by a locking bolt to accommodate different types of packaging bags, and at the same time facilitate the placement of packaging bags on the supporting plate 22; the second sub-pressing plate 342 can be fixedly connected to the frame 1, or the second sub-pressing plate 342 can be slidably connected to the frame 1 along the third direction C, and the second sub-pressing plate 342 can be fixed at a certain position by a locking bolt to accommodate different types of packaging bags, and at the same time facilitate the placement of packaging bags on the supporting plate 22.

[0090] Part of the first sub-pressing plate 341 protrudes toward the second sub-pressing plate 342 to form a bag opening tongue 32. During operation, the adsorption portion 5 adsorbs part of the first surface of the packaging bag, and under the action of the first driving portion 4, pulls the first surface of the packaging bag to move along the first direction A, so that a gap is opened in the packaging bag and aligned with the bag opening tongue 32. At this time, the bag opening tongue 32 can be inserted into the mouth of the packaging bag, limiting the movement of the second surface of the packaging bag opposite to the first surface, ensuring that the packaging bag can be opened more quickly and thoroughly when pulled by the adsorption portion 5, thereby improving the efficiency of bag opening.

[0091] The jet assembly 33 can be disposed on the first sub-pressing plate 341, and the nozzle of the jet assembly 33 faces the bag opening of the packaging bag. When the bag opening of the packaging bag is initially opened, the nozzle of the jet assembly 33 can spray air into the bag opening of the packaging bag to further improve the bag opening efficiency and ensure that the packaging bag is completely opened. The specific structure of the jet assembly 33 is known to those skilled in the art and will not be described in detail here.

[0092] The second sub-pressing plate 342 can realize the positioning of the bottom edge of the packaging bag, prevent the bottom of the packaging bag from tilting or folding, ensure the opening of the bag, and facilitate the subsequent loading of items. In addition, after the packaging bag is loaded with the product to be packaged, the second sub-pressing plate 342 can be used as a platform for transmission, and the packaging bag slides on the second sub-pressing plate 342 under the push of the second driving unit 300. The second sub-pressing plate 342 can be made of a material with a certain rigidity.

[0099] A limiting groove extending along the third direction C is formed between the two sub-pressing plates 34, and the limiting groove is directly opposite to the bag opening of the packaging bag. The second driving unit 300 can be fixedly arranged on the frame 1, and a conveyor line for conveying the packaged product along the second direction B is provided between the second driving unit 300 and the limiting groove. The second driving unit 300 pushes the bag-packaged product on the conveyor line through the limiting groove in the opposite direction of the third direction C, and ensures that the product accurately enters the opened packaging bag under the limiting function of the limiting groove. The second driving unit 300 can be a linear motor, a hydraulic cylinder or a pneumatic cylinder, etc.

[0100] Compared with the prior art, the automatic bagging device provided in Example 2 of the present application includes the bag taking mechanism 100 of Example 1, and the bag taking mechanism 100 replaces the traditional motor with an elastic member 21 and a stopper 3, while realizing the integration of the functions of tensioning, taking and opening the packaging bag, thereby greatly simplifying the structure of the equipment and reducing the manufacturing cost of the automatic bagging device. At the same time, the limiting function of the two limiting plates 200 of the device ensures that the product to be packaged pushed by the second limiting part can accurately enter the opened packaging bag, thereby improving the accuracy and stability of the use of the device.

[0101] like Figure 1 and Figure 3 As shown, in some embodiments, it also includes:

[0102] Two limiting rods 400 are arranged at intervals and opposite to each other on both sides of the carrying plate 22 along the second direction B. The first ends of the two limiting rods 400 are connected to the frame 1 for rotation around the first direction A. The second driving part 300 can push the packaging bag in the opposite direction of the third direction C. The two limiting rods 400 are used to maintain the movement path of the packaging bag in the opposite direction of the third direction C.

[0103] The second locking member is connected to the two limiting rods 400 and the frame 1 respectively, and is used to limit the rotation of the two limiting rods 400.

[0104] Specifically, the first end of the limiting rod 400 is spaced from the packaging bag by a certain distance. During the rotation of the limiting rod 400, the second end of the limiting rod 400 can contact or be spaced from the packaging bag. When the second end of the limiting rod 400 is spaced from the packaging bag, the packaging bag on the carrying plate 22 can be placed. When the second end of the limiting rod 400 contacts the packaging bag, the two limiting rods 400 cooperate with each other to provide a precise motion path guide in the opposite direction of the third direction C for the packaging bag loaded with the product, ensuring that the packaging bag can accurately and smoothly enter the next process under the push of the second driving unit 300. The second locking member is used to keep the two limiting rods 400 in a fixed position, and the second locking member can be a locking bolt or a buckle, etc.

[0105] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
