As shown in fig. 2 to 10, the sleeve core feeding device 1 comprises a charging barrel 11, a vibrator 12, a controller, a lifting assembly, a clamping assembly and a conveying assembly, wherein the charging barrel 11 is vertically arranged, the charging barrel 11 is of a cylindrical hollow structure, the top of the charging barrel 11 is open and provided with a bottom, the top of the charging barrel 11 is provided with a barrel cover 111, the bottom of the charging barrel 11 is provided with a bottom hole 112, and the bottom hole 112 is positioned in the center of the bottom of the charging barrel 11. The vibrator 12 is fixed to a side wall of the cylinder 11, and the cylinder 11 vibrates in response to the vibration of the vibrator 12 after the vibrator 12 is activated. In use, as shown in fig. 9, the sleeve 37 is added to the barrel 11 and after the vibrator 12 is activated, the sleeve 37 moves the barrel 11 through the bottom aperture 112. When in installation, the vibrator 12 is arranged on the frame, and the charging barrel 11 is suspended.

As shown in fig. 3 and 6, the lifting assembly includes a lifting block 132 and a lifting cylinder 13 driving the lifting block 132 to move, the lifting cylinder 13 is fixed at the bottom of the charging barrel 11 through a lifting cylinder bracket 131, the lifting block 132 is fixed on a piston rod of the lifting cylinder 13, the lifting block 132 is in an L-shaped structure, angle steel is selected, a vertical part of the lifting block 132 is fixedly connected with the piston rod of the lifting cylinder 13, a gasket is arranged on a horizontal part of the lifting block 132, a sleeve core 37 falling through a bottom hole 112 directly falls on the gasket, and the gasket can be made of flexible materials or hard plastics. The lifting cylinder 13 lifts the core 37 dropped through the bottom hole 112 while driving the lifting block 132 to move below the bottom hole 112. When the lifting cylinder 13 drives the lifting block 132 to move away from under the bottom hole 112, the lifting assembly no longer plays a role in lifting the sleeve 37.

As shown in fig. 2 to 5, the clamping assembly is located on the movable portion of the conveying assembly, the conveying assembly conveys the clamping assembly between the cartridge side and the discharge side, the sleeve core 37 is clamped when the clamping assembly is located on the cartridge side, and the clamping assembly is located on the discharge side to discharge the sleeve core 37. The method comprises the following steps: as shown in fig. 7, the conveying assembly includes a conveying cylinder 16 and a supporting block 17, a piston rod of the conveying cylinder 16 is fixedly connected with the supporting block 17, the clamping assembly includes a clamping cylinder 19 and clamping blocks 191, the clamping blocks 191 are two symmetrically arranged and are slidably arranged on the clamping cylinder 19, the clamping cylinder 19 is used for driving the two clamping blocks 191 to synchronously move, and the moving directions of the two clamping blocks 191 are always opposite.

The supporting block 17 is located on the piston rod of the conveying cylinder 16 and is a movable part of the conveying cylinder 16.

When the clamping assembly clamps the sleeve core 37 on the supporting block 132 and draws the sleeve core outwards, a blocking assembly is arranged at the bottom of the charging barrel 11 to prevent other sleeve cores 37 from moving out of the bottom hole 112. As shown in fig. 3 and 6, the blocking assembly includes a blocking cylinder 14 and a blocking block 141, the blocking cylinder 14 is fixed at the bottom of the cylinder 11, the blocking block 141 is two blocks symmetrically arranged, one end of the blocking block 141 is hinged with the blocking cylinder 14, the blocking cylinder 14 is used for driving the two blocks 141 to swing, and when the other end of the blocking block 141 is located below the bottom hole 112, the sleeve core 37 located in the bottom hole 112 is blocked, so as to prevent the sleeve core 37 from falling. The blocking cylinder 14 is in signal connection with a controller, and the controller sends a signal to the blocking cylinder 14 so that after the stop block 141 blocks the bottom hole 112, the lifting cylinder 13 drives the lifting block 132 to move away from the position below the bottom hole 112.

After the core 37 is dropped onto the support blocks 132, the bottom hole 112 is first blocked by the blocking assembly, then the core 37 is clamped by the clamping assembly, and then the support blocks 132 of the lifting assembly are withdrawn. To realize the detection of the sleeve core 37, so as to know that the sleeve core 37 is in contact with the supporting block 132, a sensor 15 is arranged at the bottom of the charging barrel 11, the sensor 15 and the bottom hole 112 are positioned in the same vertical plane, and when the sleeve core 37 is in contact with the supporting block 132, the sensor 15 detects the existence of the sleeve core 37. The sensor 15 is in signal communication with the controller and sends a signal to the controller when the sensor 15 detects the core 37. To facilitate the installation of the sensor 15, an L-shaped sensor holder 151 is fixed to the bottom of the cartridge 11, and the sensor 15 is fixed to the lower portion of the vertical portion of the sensor holder 151.

First, the vibrator 12 vibrates the inner sleeve 37 of the cylinder 11, as shown in fig. 10, after the sleeve 37 falls down through the bottom hole 112 and falls on the supporting block 132 during vibration, the sensor 15 detects the sleeve 37 and sends a signal to the controller, and the controller sends a signal to the blocking cylinder 14 of the blocking assembly, so that the blocking cylinder 14 drives the block 141 to swing until the block 141 blocks the bottom hole 112 from below, and at this time, the sleeve 37 is located between the two blocks 141 but is not in contact with the block 141. Subsequently, the controller sends a signal to the delivery cylinder 16, causing the delivery cylinder 16 piston rod to retract, as shown in fig. 11, causing the clamp assembly to move toward the cartridge 11 side until the delivery cylinder 16 piston rod retract amount reaches the set point. Subsequently, the controller sends a signal to the feed cylinder 18, and the feed cylinder 18 acts to push the clamping assembly toward the core 37 side until the clamp blocks 191 move to both sides of the core 37. The controller then sends a signal to the clamping cylinder 19, and the clamping cylinder 19 acts to force the clamp block 191 to clamp the sleeve 37. The controller then sends a signal to the lift cylinder 13, as shown in fig. 12, the lift cylinder 13 drives the shoe 132 out of under the bottom hole 12. Subsequently, the rotation of the turntable 171 rotates the clamping assembly until the core 37 rotates to a horizontal state. Subsequently, the controller sends a signal to the transfer cylinder 16, as shown in fig. 13, the extension of the transfer cylinder 16 piston rod moves the clamp assembly, the sleeve 37, to the discharge side until the transfer cylinder 16 piston rod extension reaches the set point. At the same time, the controller sends a signal to the lifting cylinder 13, and the lifting cylinder 13 drives the lifting block 132 to move below the bottom hole 112 again; the controller sends a signal to the blocking cylinder 14, and the blocking cylinder 14 acts to drive the stop block 141 to unblock the bottom hole 112. The controller then sends a signal to the clamp cylinder 19, and the clamp cylinder 19 acts to release the core 37 so that the core 37 falls onto the conveyor 31. The controller then sends a signal to the feed cylinder 18, and retraction of the feed cylinder 18 piston rod pulls the clamp assembly upward. Subsequently, the turntable 171 is rotated in the reverse direction, so that the clamp assembly is reset.
