[0023] The figure includes:

[0024] Carrying base 1, vertical rotating shaft 11, lifting sleeve 12, lifting guide seat 13, lifting frame 14, cantilever 2, suction cup frame 3, suction cup 31, buffer device 32, synchronous belt 4, first synchronous belt pulley 41, second synchronous belt pulley 42. Specific implementation manner

[0025] The core of the present invention is to provide a turret type bag transferring device, which has a small occupied space and flexible layout by arranging a rotary transfer structure on the side of the conveyor belt.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the turret type bag transferring device of the present invention will be introduced and described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0027] As Figure 1A shown, it is the front elevation sectional view structure diagram of the turret type bag transferring device provided by the present invention; Figure 2A It is the side elevation sectional view of the turret type bag transferring device provided by the present invention; the turret type bag transferring device includes structures such as a carrying base 1, a cantilever 2, and a suction cup frame 3. The carrying base 1 is arranged on one side of the conveyor belt and serves as the carrying structure of the entire turret type bag transferring device to determine the overall position, and other components are installed thereon.

[0028] The cantilever 2 extends horizontally, and its first end is rotatably connected to the carrying base 1 through the vertical rotating shaft 11; the first end refers to Figure 1A the right end in, and the second end is Figure 1A the left end in. The length direction of the vertical rotating shaft 11 is perpendicular to the length direction of the cantilever 2. The cantilever 2 rotates around the vertical rotating shaft 11 in the horizontal direction and can rotate to any angle. A rotary drive is installed on the carrying base 1, and the vertical rotating shaft 11 is driven by the rotary drive installed on the carrying base 1, so that the cantilever 2 rotates relative to the carrying base 1.

[0029] The suction cup frame 3 is installed at the second end of the cantilever 2. The suction cup frame 3 is driven by the cantilever 2 to rotate. The suction cup frame 3 takes the vertical rotating shaft 11 as the rotation axis and revolves relative to the vertical rotating shaft 11 driven by the cantilever 2.

[0030] The cantilever 2 drives the suction cup frame 3 to rotate to different workstations, and the angles of the cantilever 2 at different workstations are different; a plurality of suction cups 31 are arranged in an array on the suction cup frame 3, and the suction cup frame 3 drives the suction cups 31 to move synchronously; the suction cups 31 are connected to the vacuum tube. According to the size of the flexible bag, one flexible bag can correspond to one suction cup 31, or one flexible bag can correspond to two or more flexible bags. One flexible bag is sucked by a single or multiple suction cups 31; the suction cups 31 generate negative pressure through the vacuum tube, and the flexible bag is pressed on the suction cups 31 by the pressure difference on both sides of the flexible bag.

[0031] The turret type bag transferring device of the present invention transfers the flexible bags in a rotating manner. The turret type bag transferring device is placed at the intersection of two conveyor belts. The suction cup frame 3 can be driven by the cantilever 2 to move above the two conveyor belts or move out. When the two conveyor belts intersect perpendicularly, the rotation angle range of the cantilever 2 is 90 degrees; since the suction cup frame 3 is installed in a cantilever manner, it does not need to span across the conveyor belt, saving space occupation and eliminating the need to set up a frame structure. It has a more flexible layout compared to the cage type bag unloading machine and is convenient for maintenance when set on one side of the conveyor belt; when the suction cup frame 3 moves out above the conveyor belt, space is vacated above the conveyor belt, facilitating the removal of the flexible bags that have not been sucked out.

[0032] On the basis of the above scheme, the vertical rotating shaft 11 of the present invention is rotationally inserted into the lifting sleeve 12. The vertical rotating shaft 11 can rotate relative to the lifting sleeve 12, and the vertical rotating shaft 11 and the lifting sleeve 12 can move up and down synchronously; the lifting sleeve 12 is slidably inserted into the lifting guide seat 13, and the lifting sleeve 12 can move up and down and rotate relative to the lifting guide seat 13. As Figure 1B shown, it is the Figure 1A partial structure diagram at the vertical rotating shaft 11; the bottom of the lifting sleeve 12 is connected to the lifting frame 14. The lifting frame 14 provides support for the lifting sleeve 12 and the vertical rotating shaft 11. The lifting frame 14 drives the lifting sleeve 12 and the vertical rotating shaft 11 to move vertically relative to the lifting guide seat 13, thereby driving the cantilever 2 to lift; as Figure 1A and Figure 2A shown, the lifting frame 14 of the present invention is arranged inside the bearing base 1. A driving device such as a cylinder or an oil cylinder is arranged at the bottom of the lifting frame 14 to drive the lifting. When the lifting frame 14 lifts, it synchronously drives the lifting sleeve 12 and the vertical rotating shaft 11 installed thereon to move; a rotating driver for the vertical rotating shaft 11 is also installed on the lifting frame 14, and the vertical rotating shaft 11 can rotate to any angle at any height.

[0033] As shown Figure 2B in, it is a partial enlarged view of part A in Figure 2A . A buffer device 32 is provided on the suction cup frame 3. The suction cup 31 is connected to the suction cup frame 3 through the buffer device 32. The buffer device 32 can produce elastic deformation. When grasping a soft bag, the suction cup frame 3 moves downward. When it contacts the soft bag, an adsorption force is generated through the negative pressure effect. Due to the provision of the buffer device 32, with the same descending distance of the suction cup frame 3, the greater the thickness of the soft bag, the greater the elastic deformation amount generated by the buffer device 32 and the higher the compression degree. Thus, it is applicable to soft bags of different thicknesses. By providing the buffer device 32, the applicable range of soft bags is wider. When the thickness difference of the soft bags is not too large, there is no need to adjust the descending distance of the suction cup frame 3.

[0034] Specifically, the buffer device 32 in the present invention includes a guide rod, a guide slider and a spring. The guide rod is installed on the suction cup frame 3, the guide slider is installed on the suction cup 31, and the spring is installed between the guide rod and the guide slider. The guide slider can move vertically along the guide rod, thereby generating a thrust on the spring and changing the compression amount of the spring.

[0035] A one-way valve is provided on each suction cup 31 in the present invention. The one-way valve is used to prevent air leakage from affecting other suction cups 31. When only individual suction cups leak air, it does not affect the grasping process of other suction cups. Multiple suction cups 31 are provided on the suction cup frame 3, and different grasping quantities such as grasping a whole tray or a half tray can be achieved.

[0036] Based on any of the above technical solutions and their combinations, the suction cup frame 3 of the present invention is rotatably connected to the cantilever 2. The suction cup frame 3 adjusts its orientation through an angle adjustment device, that is, adjusts the angle of the suction cup frame 3 through the angle adjustment device, and the suction cup frame 3 can achieve self-rotation. After the suction cup frame 3 grasps a tray of soft bags, by changing the angle of the suction cup frame 3, the soft bags can be placed at any angle.

[0037] The present invention provides a specific setting form of the angle adjustment device herein. Combining Figure 1A as shown in, the angle adjustment device includes a first synchronous pulley 41, a second synchronous pulley 42 and a synchronous belt 4. The first synchronous pulley 41 is provided on the vertical rotating shaft 11. The first synchronous pulley 41 and the vertical rotating shaft 11 rotate synchronously, and the two are connected by a key. The second synchronous pulley 42 is provided on the suction cup frame 3. The second synchronous pulley 42 and the suction cup frame 3 rotate synchronously, and the two are connected by a key. An annular synchronous belt 4 is provided between the first synchronous pulley 41 and the second synchronous pulley 42, and the synchronous belt 4 is respectively meshed with the first synchronous pulley 41 and the second synchronous pulley 42 for transmission.

[0038] Since the first synchronous pulley 41 and the vertical rotating shaft 11 rotate synchronously, when the vertical rotating shaft 11 rotates to change the angle of the cantilever 2, the first synchronous pulley 41 rotates synchronously. The rotation of the first synchronous pulley 41 drives the synchronous belt 4 to rotate, and the rotation of the synchronous belt 4 further drives the second synchronous pulley 42 to rotate. The second synchronous pulley 42 causes the suction cup frame 3 to rotate. While the cantilever 2 revolves relative to the vertical rotating shaft 11, the suction cup frame 3 can rotate on its own axis.

[0039] When the cantilever 2 revolves, it generates a centripetal force on the soft bag. When the suction cup frame 3 rotates on its own axis, it constantly changes the orientation of the soft bag. The centripetal force of the soft bag will not be in only one direction, so the risk of dropping can be reduced.

[0040] Adopting the above structure does not require a separate drive structure, which is beneficial to simplifying the solution; when the orientation angle of the suction cup frame 3 needs to be adjusted, the tooth ratio of the first synchronous pulley 41 and the second synchronous pulley 42 can be changed. The synchronous belt 4 can be a belt or a chain, and correspondingly, the first synchronous pulley 41 and the second synchronous pulley 42 are respectively a gear or a sprocket to prevent slipping.

[0041] As Figure 3 shown, it is a top view of the turret type bag transferring device of the present invention cooperating with two conveyor belts; where A represents the turret type bag transferring device of the present invention, B represents the conveyor belt for taking out the soft bag, in the form of a roller shaft, and C0 is the position of the soft bag on the conveyor belt for taking out the soft bag; C1 to C4 represent four states after the soft bag is transferred and placed through the turret type bag transferring device of the present invention. The four arrows in the figure respectively represent the orientation of the bag mouth of the soft bag.

[0042] The positions of C1 and C4 represent the situation where the suction cup frame 3 rotates 90 degrees on its own axis by using the synchronous belt 4; C1 is obtained by rotating 90 degrees counterclockwise from the position of C0, and C4 is obtained by rotating 90 degrees clockwise from the position of C0. C1 to C4 are listed in the figure only for convenient display. The positions of C2 and C3 represent the situation where the suction cup frame 3 does not rotate on its own axis; C2 is obtained by rotating 90 degrees counterclockwise from the position of C0, and C3 is obtained by rotating 90 degrees clockwise from the position of C0.

[0043] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather will be accorded the widest scope consistent with the principles and novel features disclosed herein.
