In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0040] The present invention provides a box-holding transfer assembly, including a box-holding mechanism 100, which includes a first rotating member 110, at least two claw telescoping mechanisms 120, and at least two claws 130; the claws 130 are connected to the first rotating member 110 through the claw telescoping mechanisms 120; the first rotating member 110 is connected to a power source and driven by the power source to rotate, and at least two claw telescoping mechanisms 120 are all connected to the first rotating member 110, so that the claws 130 approach or move away from each other synchronously under the drive of the first rotating member 110 and the claw telescoping mechanisms 120.

[0041] During specific implementation, as Figures 1-4 shown, this embodiment is a box-holding transfer assembly with two claws 130. The two claws 130 are respectively connected to a claw telescoping mechanism 120, and the two claw telescoping mechanisms 120 are both connected to the first rotating member 110. The first rotating member 110 is connected to a power source to transmit power and drive the movement of the two claw telescoping mechanisms 120, thereby driving the movement of the claws 130, so that the two claws 130 approach or move away from each other to perform the box-holding operation. Preferably, more than two groups of claws 130 and claw telescoping mechanisms 120 can be provided and driven by a first rotating member 110.

[0042] In this embodiment, by connecting the two claw telescoping mechanisms 130 in the box-holding mechanism 100 to the first rotating member 110, the power of the power source is transmitted through the first rotating member 110 to drive the two claw telescoping mechanisms 120 to act synchronously, driving the claws 130 to approach or move away from each other. Compared with the prior art in which each claw is provided with a separate cylinder or hydraulic cylinder as a power source, the number of power sources is saved, the assembly and debugging process of the assembly is simplified, and the synchronous control of the claw movement is facilitated.

[0043] Specifically, as Figure 1 shown, the box-holding mechanism 100 further includes a first mounting bracket 140. The two claw telescoping mechanisms 120 and the claws 130 are symmetrically arranged on both sides of the first mounting bracket 140. The claw telescoping mechanism 120 includes a U-direction linear motion mechanism 121 and a transmission mechanism 122, where the U-direction linear motion mechanism 121 is as Figure 3As shown in the figure, it includes a U-direction slideway 121a and a first slider 121b. The U-direction slideway 121a is fixedly arranged on one side of the first mounting bracket 140. The first slider 121b is slidably connected to the U-direction slideway 121a. The gripper 130 is adjustably mounted at one end of the first slider 121b. The other end of the first slider 121b is connected to the transmission mechanism 122. The transmission mechanism 122 drives the gripper 130 to move along the U-direction slideway 121a through the first slider 121b, where the U direction is the direction for the predetermined gripper 130 to approach the magazine. Preferably, in this embodiment, the U direction is horizontal and forms an angle of 20 - 70 degrees with the axial direction of the first axis 310, which is the magazine transfer direction in this embodiment. When the two symmetrically arranged grippers 130 move synchronously in their respective U directions, they perform an oblique clamping or loosening movement relative to the magazine, and they approach or move away from each other.

[0044] Specifically, as Figure 2 shown in the figure, the transmission mechanism 122 includes a first rotating arm 122a fixedly connected to the first rotating member 110, a first fork 122b having a first strip-shaped notch, a second slideway 122c fixedly arranged on the side of the first mounting bracket 140, and a connecting rod 122d connecting the first fork 122b and the first slider 121b. On the one hand, the transmission mechanism 122 is connected to the U-direction linear motion mechanism 121 through the connecting rod 122d. On the other hand, it is connected to the first rotating member 110 through the first rotating arm 122a for transmitting power to drive the gripper 130 to move by the U-direction braking mechanism 121. Wherein, on the side of the first rotating arm 122a far from the first rotating member 110, there is a first dial block. The first dial block of the first rotating arm 122a is located in the first strip-shaped notch of the first fork 122b to form a high pair contact. The middle part of the first fork 122b is slidably connected to the second slideway 122c. The bottom end of the first fork 122b is hinged to one end of the connecting rod 122d. When the first rotating member 110 drives the first rotating arm 122a to rotate, it drives the first fork 122b to move along the second slideway 122c through the high pair contact, and then drives the first slider 121b hinged to the other end of the connecting rod 122d to move along the U-direction slideway 121a through the connecting rod 122d. Preferably, the first dial block adopts but is not limited to a rolling structure to reduce the sliding friction of the high pair contact surface. The sliding track of the second slideway 122c is a direction parallel and horizontal to the rotating surface of the first rotating arm 122a to facilitate the production and installation of the mechanism. The hinge points at both ends of the connecting rod 122d are located in the same plane or in different planes respectively, and their hinge axes are all in the vertical direction and are not limited to the vertical direction, which is convenient for the production, installation and debugging of the mechanism.

[0045] In this embodiment, the gripper telescopic mechanism 120 converts the rotation of the first rotating member 110 on the vertical plane of the cartridge transfer into the U-direction linear motion of the gripper through the cooperation of the transmission mechanism 122 and the U-direction linear motion mechanism 121 to realize the clamping or loosening of the cartridge. By means of a mechanical structure, multiple grippers are driven to act synchronously by a distal rotating power source. Compared with the prior art in which multiple linear power sources are directly used to drive each gripper respectively, it is convenient for installation and debugging during the production process and synchronous control during the use process.

[0046] Preferably, the cartridge transfer assembly further includes a lifting mechanism 200 for controlling the lifting motion of the cartridge holding mechanism 100, including a second rotating member 210 and a Z-direction linear motion mechanism 220. On the one hand, the second rotating member 210 is connected to a power source to transmit power. On the other hand, it is connected to the cartridge holding mechanism 100 through the Z-direction linear motion mechanism 220 to drive the lifting motion of the cartridge holding mechanism 100 along the gravity direction.

[0047] Specifically, as Figure 4 shown, the Z-direction linear motion mechanism 220 includes a second rotating arm 221 fixedly connected to the second rotating member 210, a second mounting bracket 222, a second fork 223 having a second strip-shaped notch, and a second slider 224 slidably connected to the second mounting bracket 222; a second blocking block is provided on the side of the second rotating arm 221 away from the second rotating member 210. The second rotating arm 221 forms a high pair connection by arranging the second blocking block in the second strip-shaped notch of the second fork 223. The second mounting bracket 222 is provided with a vertical Z-direction slideway, and is slidably connected to the first mounting bracket 140 through the Z-direction slideway and the second slider 224. The second fork 223 is fixedly connected to the first mounting bracket 140. When the second rotating arm 221 rotates with the second rotating member 210, it drives the first mounting bracket 140 to move along the Z-direction slideway through the second fork 223, that is, drives the lifting motion of the cartridge holding mechanism 100. Preferably, the second blocking block adopts but is not limited to a rolling structure to reduce the sliding friction of the high pair contact surface; second rotating arms 221 and second forks 223 are provided on both sides of the second mounting bracket 222 to share the torque required for the lifting motion.

[0048] In this embodiment, the lifting mechanism 200 replaces the hydraulic cylinder and cylinder in the prior art to drive the lifting motion by adopting the second rotating arm 221, the second fork 223 and the Z-direction sliding pair, which is beneficial to assembly and debugging during production and control during use. Compared with linear drive mechanisms such as gear racks or ball screw nut mechanisms, the lifting mechanism 200 in this embodiment has the advantage of lower production cost.

[0049] Preferably, as Figure 1 and Figure 3In this embodiment, the first rotating member 110 is connected to the power source through the first shaft 310, and the second rotating member 210 is connected to the power source through the second shaft 320. The power sources of the first rotating member 110 and the second rotating member 210 can be shared or different power sources can be used separately. The first shaft 310 can be, but is not limited to, a spline shaft to form a circumferential fixed connection with the first rotating member 110 as a rotating shaft for power transmission, and is axially slidably connected to the first rotating member 110 as a slide rail for the box holding mechanism and the lifting mechanism. The second shaft 320 can be, but is not limited to, a spline shaft to form a circumferential fixed connection with the second rotating member 210 as a rotating shaft for power transmission, and is axially slidably connected to the second rotating member 210 as a slide rail for the box holding mechanism and the lifting mechanism. Both the first rotating member 110 and the second rotating member 210 are rotatably connected to the second mounting bracket 222, that is, the rotation centers of the first shaft 310 and the second shaft 320 are fixed relative to the second mounting bracket 222. The first shaft 310 and the second shaft 320 jointly pass through the second mounting bracket 222 as the slide rails of the lifting mechanism 200 and the box holding mechanism 100.

[0050] Preferably, as Figure 2 shown, in this embodiment, it is applied to transport square boxes, and the gripper 130 is of an L-shaped structure. It does not exclude the change in the shape of the gripper 130 when transporting boxes of other shapes. The gripper 130 further includes a gripper adjusting mechanism 131 and a suction cup 132. The suction cup 132 is fixedly connected to the gripper. The gripper 130 and the suction cup 132 are jointly connected to the end of the first slider 121b through the gripper adjusting mechanism 131. The two grippers 130 adjust their relative positions through the gripper adjusting mechanism 131, so that the box holding mechanism 100 can adapt to boxes of different specifications and sizes, improving the adaptability of the mechanism.

[0051] During actual use, the lifting mechanism 200 drives the box holding mechanism 100 to move downward. The box holding mechanism 100 drives the gripper 130 to extend through the transmission mechanism 122 and the U-shaped linear motion mechanism 121 to pick up the box. The lifting mechanism 200 drives the box holding mechanism 100 and the box to rise. The whole formed by the lifting mechanism 200 and the box holding mechanism 100 is driven by the transverse movement mechanism to move axially along the first shaft 310 and the second shaft 320, transporting the box to the next working station to realize automatic feeding. By using a mechanical structure to replace the multi-power source structure in the prior art, the installation, debugging and use costs are reduced, and the production cost is reduced. And the problem of variable-direction transmission is solved through the transmission mechanism 122 and the U-shaped linear motion mechanism 121, making the mechanical structure simple and further reducing the production cost.

[0052] The present invention also provides a box holding and transferring device, including two relatively arranged box holding and transferring components as described in any one of the above.

[0053] The present invention also provides a packaging box production equipment, using the box holding and transferring component as described in any one of the above or a box holding and transferring device as described above.

[0054] Although terms such as a holding box mechanism, a first rotating member, a holding claw telescopic mechanism, a U-direction linear motion mechanism, a U-direction slideway, a first slider, a transmission mechanism, a first swing arm, a first fork, a second slideway, a connecting rod, a holding claw, a holding claw adjusting mechanism, a suction cup, a first mounting bracket, a lifting mechanism, a second rotating member, a Z-direction linear motion mechanism, a second swing arm, a second mounting bracket, a second fork, a second slider, a first shaft, and a second shaft are used more frequently in this text, the possibility of using other terms is not excluded. These terms are only used to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
