In this embodiment, the box transporting mechanism 1 is preferably a roller way transporting mechanism, the box transporting mechanism 1 includes a frame 15, a first transporting roller set 16 is rotatably disposed at one end of the frame 15 far away from the rotating shaft 21 along a horizontal direction, a plurality of second transporting roller sets 17 are disposed at one end of the frame 15 near the rotating shaft 21, the plurality of second transporting roller sets 17 are disposed at intervals in a vertical transporting direction, at least one second transporting roller set 17 of the plurality of second transporting roller sets 17 is rotatably positioned between two sets of overturning brackets 23 and connected with the first transporting roller set 16 through a belt transmission, the first transporting roller set 16 and the second transporting roller set 17 cooperate together to form a horizontal transporting surface 13, and the adjacent second transporting roller sets 17 form the movable groove 14 at intervals. During operation, the first conveying roller set 16 of the motion initial box conveying mechanism 1 (the first box conveying mechanism 11 or the second box conveying mechanism 12) is responsible for stably conveying box products from the input end to the vicinity of the overturning bracket 23, and then the second conveying roller set 17 continues to convey the box products, so that the side wall of the advancing end of the box products is abutted against the second positioning surface 232 of the abutting overturning bracket 23, the box products are ensured to fully contact the overturning bracket 23 before overturning, and overturning motion is carried out under the support of the overturning bracket 23, so that safety accidents caused by the fact that the box products are separated from the overturning bracket 23 due to too fast overturning speed in the overturning process are avoided, and the improvement of the overturning stability and safety of the box products is facilitated.

The anti-slip layer 241 may be fixed on the first positioning surface 231 and the second positioning surface 232 by means of adhesion, spraying, injection molding, etc., and the specific mounting mode is selected depending on the material and thickness of the anti-slip layer 241 and the material and structure of the overturning bracket 23.

Besides the anti-slip layer 241, the fixing structure 24 can further set a plurality of negative pressure holes 242 on the first positioning surface 231 and the second positioning surface 232 of the turnover support 23, the negative pressure holes 242 are communicated with a negative pressure device such as an air pump, when the box product contacts the turnover support 23, the opening of the negative pressure holes 242 can form a negative pressure area under the action of the negative pressure device, and the box product is tightly adsorbed on the turnover support 23, so that the effect of increasing the contact force between the box product and the turnover support 23 is achieved, the static friction force between the box product and the turnover support 23 is increased, the stability of the box product in the turnover process is improved, and in addition, the abrasion and noise caused by friction can be reduced by arranging a negative pressure port to adsorb and fix the box product.

It should be noted that the above-mentioned scheme of the anti-slip layer 241 and the scheme of the negative pressure hole 242 of the fixing structure 24 may be implemented independently, or may be used in combination with each other, that is, the anti-slip layer 241 and the negative pressure hole 242 are provided on the overturning bracket 23, the anti-slip layer 241 is provided on the first positioning surface 231 and the second positioning surface 232, and preferably made of elastic materials such as silica gel and rubber, the negative pressure hole 242 is provided on the first positioning surface 231 and the second positioning surface 232, and the negative pressure hole 242 penetrates through the anti-slip layer 241. In operation, the anti-slip layer 241 made of elastic material has good elasticity and adaptability, can closely adhere to the surface of the box product, fills the tiny gap between the box product and the overturning bracket 23, and further forms an effective sealing environment, which is critical to negative pressure adsorption, because it can prevent air from leaking from the gap, improves the air tightness of the negative pressure hole 242 for negative pressure adsorption of the box product, thereby ensuring that enough negative pressure can be generated in the negative pressure hole 242 to fix the box product, and improving the stability of negative pressure adsorption.

Further, in this embodiment, the box turnover transporting device further includes a buffer assembly 4 for elastically buffering and supporting the box product after the box product is turned over, the buffer assembly 4 includes an elastic member 41 penetrating through the horizontal transporting surface 13 of the target box transporting mechanism 1 (when the box product is turned over and lifted from the first box transporting mechanism 11 to the second box transporting mechanism 12, the second box transporting mechanism 12 is the target box transporting mechanism 1), one end of the elastic member 41 is higher than the horizontal transporting surface 13 of the box transporting mechanism 1 and is connected with a pressing plate 42 for abutting the bottom of the box product, and one end of the elastic member 41 away from the pressing plate 42 is connected to the box transporting mechanism 1. When the box product is turned over and falls on the pressing plate 42, the elastic member 41 is deformed, absorbs part of impact energy to protect the box product from damage, and supports the box product by its elastic restoring force. The elastic piece 41 can be made of elastic materials and has smooth surfaces, the pressing plate 42 is made of elastic materials and can further play a buffering role when contacting with the box product, damage to the surface of the box product is avoided, the surface of the pressing plate 42 is smooth so as to reduce friction between the pressing plate 42 and the box product, and the pressing plate 42 is convenient to separate from the surface of the box product after buffering and supporting the box product.

Specifically, the buffer assembly 4 includes an arc-shaped telescopic rod 43, the fixed end of the arc-shaped telescopic rod 43 is connected to the box transporting mechanism 1, the telescopic end of the arc-shaped telescopic rod is connected to the pressing plate 42, and the elastic member 41 is a spring and is sleeved on the arc-shaped telescopic rod 43. The arcuate telescoping rod 43 is arcuate in shape, which helps to better accommodate the overturning path of the box product and reduce friction and drag during overturning.

Further, in order to increase the height of the turnover support 23 to drive the box body product to turn over and lift, in this embodiment, the horizontal conveying surface 13 of the first box conveying mechanism 11 is arranged at a low position relative to the axis of rotation 21 of the rotation shaft 21, which is shown in the drawing, and the rotation shaft 21 is disposed between the horizontal conveying surfaces 13 of the first box conveying mechanism 11 and the second box conveying mechanism 12. In the case turning transporting device, the turning lifting height refers to the height change of the case product relative to the initial position in the turning process, and the turning height can be obviously influenced by adjusting the relative position between the horizontal transporting surface 13 of the first case transporting mechanism 11 and the rotating shaft 21 of the rotating shaft 21. In this embodiment, the horizontal conveying surface 13 of the first box conveying mechanism 11 is disposed at a position below the axis of the rotating shaft 21, so that the box product is at a lower position at the initial stage of overturning, when the rotating shaft 21 rotates, the box product will rise along the predetermined overturning track until reaching the highest point, and under the condition that the length of the connecting body 22 is fixed, the box product will undergo a larger height change during overturning due to the lower initial position, so that the overturning lifting height is increased.
