Figure 1 , Figure 2 As shown, the device includes a baffle synchronous belt transmission module 1, a pan / tilt module 2, an arc slide rail module 3, a mounting base plate 4, an article storage base plate 5, and a limit baffle assembly;

[0034] like Figure 4 , Figure 5As shown, the baffle synchronous belt transmission module 1 includes a baffle synchronous belt 1-1, an upper support plate 1-2, a lower support plate 1-3, a height pad 1-4, a pad 1-5 between the upper and lower support plates, a driven wheel 1-6, a driving wheel 1-7, a shaft lock 1-8, a synchronous belt motor 1-9, a synchronous belt encoder 1-10, a synchronous belt encoder fixing column 1-11, a shoulder screw, a shoulder screw nut, a screw, a nut, and a bearing. Specifically, the baffle synchronous belt 1-1 includes a synchronous belt and a baffle combination perpendicular to the surface of the synchronous belt. The distance between the baffles is set according to the object to be transmitted. The surface of the synchronous belt is perpendicular to the ground, and the baffle is used to limit the transmission on the side of the object to be transmitted. The upper support plate 1-2 and the lower support plate 1-3 serve as fixed support planes, located above and below the baffle synchronous belt; the upper support plate 1-2 fixes the synchronous belt motor 1-9, and the lower support plate 1-3 fixes the synchronous belt encoder 1-10. At the same time, the bearings are embedded in the front and rear holes to facilitate the smooth rotation of the shaft and shoulder screws of the driving wheel 1-7. The synchronous belt motor 1-9 is connected to the driving wheel 1-7 through the shaft lock 1-8, located at one end of the baffle synchronous belt, and is used to drive the driving wheel 1-7 to drive the baffle synchronous belt 1-1 to rotate. The upper and lower grooves of the driven wheel 1-6 are embedded with bearings and are flush with the driving wheel 1-7, located at the other end of the baffle synchronous belt. The shaft of the driving wheel 1-7 passes through the lower support plate 1-3 and is connected to the synchronous belt encoder 1-10, so that the movement position of the baffle synchronous belt can be accurately controlled, and the synchronous belt encoder 1-10 is fixed to the lower support plate 1-3 through the synchronous belt encoder fixing column 1-11. The driven wheel 1-6 is fixed by a shoulder screw that passes through the embedded bearing of the upper support plate, the driven wheel 1-6 and the embedded bearing of the lower support plate in sequence, and finally the shoulder screw nut is added to lock the whole. The spacer 1-5 between the upper and lower support plates is located between the upper support plate 1-2 and the lower support plate 1-3, and is used to support the spacing between the upper and lower plates and prevent the baffle synchronous belt 1-1 from sinking in during movement. The front and rear semicircular arcs of the baffle synchronous belt 1-1 are coaxial with the driving wheel 1-7 and the driven wheel 1-6, and its movement is driven by the driving wheel 1-7. The height pad 1-4 is used to connect the baffle synchronous belt transmission module with the item storage bottom plate 5 to adjust the height of the baffle synchronous belt transmission module.

[0036] The pan-tilt module 2 is driven by the motor 2-6 to drive the motor gear 2-8 to drive the pan-tilt gear 2-2 to rotate. The pan-tilt gear 2-2 is embedded with the pan-tilt bearing 2-1, and the upper gasket 2-4 of the pan-tilt gear has a flange, which passes through the pan-tilt bearing 2-1 and sandwiches the pan-tilt bearing 2-1 with the pan-tilt gear 2-2 to achieve smooth rotation inside and outside. At the same time, the upper gasket 2-4 of the pan-tilt gear and the lower gasket 2-3 of the pan-tilt gear sandwich the pan-tilt bearing 2-1 up and down to prevent the pan-tilt bearing 2-1 from sliding up and down. The rotating plate 2-5 is fixed on the upper surface of the pan-tilt gear 2-2, and the item storage bottom plate support tube 2-11 is fixed on the upper surface of the rotating plate 2-5, so that the item storage bottom plate support tube 2-11 and the rotating plate 2-5 rotate together with the pan-tilt gear 2-2. The pan-tilt gear 2-2, pan-tilt motor 2-6 and pan-tilt encoder 2-7 are fixed on the mounting base plate 4. The pad column 2-10 is located between the mounting hole of the pan-tilt encoder 2-7 and the mounting hole of the mounting base plate 4, and is used to reinforce and adjust the installation of the encoder 2-7. The encoder gear 2-9 is installed on the pan-tilt encoder 2-7 to help the encoder record the pan-tilt rotation angle. The motor gear 2-8 is installed on the pan-tilt motor 2-6. Both are installed in conjunction with the pan-tilt gear 2-2 to form a transmission device. The motor gear drives the pan-tilt gear and the encoder gear to rotate.

[0037] The arc slide rail module 3 is as follows Figure 8 , Fig. 9 As shown, it includes an arc slider 3-1, an arc slide rail 3-2, a shoulder screw, a nut, a pulley 3-3, a pulley bearing 3-4, an angle limit block 3-5, and a support sleeve 3-6. The shoulder screw in the arc slide rail module 3 passes through the arc slider 3-1, the support sleeve 3-6, the pulley bearing 3-4 and the pulley 3-3, and is finally locked by a nut; and there are four such fixed structures to form a whole slider assembly. The pulley 3-3 has grooves on the top and bottom to embed the pulley bearing 3-4. After the shoulder screw passes through the pulley bearing 3-4, the pulley 3-3 and the shoulder screw can rotate smoothly relative to each other. The slider assembly is installed on the arc slide rail 3-2 through the pulley 3-3, and the angle limit blocks 3-5 are installed at both ends of the arc slide rail to determine the range of movement of the slider assembly. At the same time, the arc slide rail module 3 is also connected to the mounting base plate 4 through the arc slide rail 3-2.

[0038] The item storage base plate 5 is installed on the pan / tilt module 2 and is directly connected to the item storage base plate support tube 2-11. At the same time, the baffle synchronous belt transmission module 1, the outer front limit 6-3 and the outer rear limit 6-4 are installed on the item storage base plate 5.

[0039] The limit baffle assembly is as follows Fig.10 As shown, it includes a front limit stop 6-1 of the baffle synchronous belt module, a rear limit stop 6-2 of the baffle synchronous belt module, an outer front limit stop 6-3, an outer rear limit stop 6-4, a central transfer pad 6-5, and a central transfer baffle 6-6.

[0040] like Figure 1 , Figure 2 As shown, the baffle synchronous belt module front limit 6-1 and the baffle synchronous belt module rear limit 6-2 in the limit baffle assembly are directly installed on the baffle synchronous belt transmission module, and together with the outer front limit 6-3 and the outer rear limit 6-4 installed on the object storage bottom plate 5, they play a role in limiting the posture of the cylindrical object. The central transfer baffle 6-6 is installed on the central transfer pad 6-5 to guide the central transfer of the cylindrical object.

[0041] The mounting base plate 4 is used to fix the pan / tilt module, the arc slide rail module 3 and the central transfer pad 6-5, and serves as a device mounting platform. The pan / tilt module and the arc slide rail module have the same rotation center, and the arc slider in the arc slide rail module moves with the rotation of the pan / tilt module. The baffle synchronous belt transmission module is located above the pan / tilt module and the arc slide rail module, and the baffle synchronous belt transmission module is fixed on the item storage base plate. The pan / tilt module and the arc slide rail module are directly connected to the item storage base plate. The pan / tilt module drives the item storage base plate to move, and then drives the movement of the baffle synchronous belt transmission module and the arc slide rail module.

[0042] The baffle synchronous belt transmission module, the pan / tilt module, and the arc slide rail module together constitute a movable transmission device. With the central transfer pad as the center, movable transmission devices are respectively arranged on both sides of its center line; Figure 3 As shown in (b), in the unfolded transmission state, the pan / tilt module 2 drives the article storage bottom plate 5 to rotate to the angle limit block 3-5 on the inner side of the arc slide rail module. The mechanism is in a V-shaped state as a whole, and the baffle synchronous belt transmission module 1 starts to start the transmission of cylindrical articles from the movable transmission device on one side. Under the joint action of the limit baffle combination, the cylindrical articles are ensured to be transmitted in a stable posture and can be transferred to the movable transmission device on the other side in a changing direction at the center. When unfolded, the outer rear limit is close to the central transfer baffle, and together with the central transfer baffle, it forms a channel for corner transmission; as shown in FIG. Figure 3 As shown in (a), when retracted, the outer rear limit moves away from the central transfer baffle and the corner transmission channel is closed.

[0043] In the retracted state, the pan / tilt module 2 drives the article storage base plate 5 to rotate to the outer angle limiting block 3 - 5 to be in the retracted state.

[0044] Combination Figure 1-Figure 9The invention controls the deformation of the device through the pan-tilt module 2, switches between different states, and transmits or stores cylindrical objects through the baffle synchronous belt transmission module 1. The position-limiting baffle combination ensures that the posture of the cylindrical objects remains unchanged. At the same time, the unique V-shaped structure of the device can realize the effective transmission of cylindrical objects in a changing direction. The overall device can comprehensively solve the storage size problem, the posture problem of transmitting cylindrical objects, and the additional transmission and changing direction function.
