Detailed Description
Referring to the drawings, a shuttle peg sleeve feeding device comprises a funnel-shaped storage bin 1, wherein a discharge hole 11 is formed in the bottom of the funnel-shaped storage bin, a conical discharge screw rod 2 in the vertical direction is arranged in the storage bin, and the screw rod is connected with a motor; a rotary table 3 is arranged at the bottom of the funnel-shaped storage bin and is connected with a motor 21; two groups of circular arc-shaped discharging guide plates are symmetrically distributed along the radial direction above the turntable, each group of discharging guide plates comprises a long guide plate 32 and a short guide plate 31 arranged in opposite directions, the long guide plates 32 are fixedly connected with a discharging hole at the bottom of the storage bin, the short guide plates 31 are fixedly connected with a frame 3, a circumferential discharging hole 33 is arranged below the short guide plates, and the height from the lower side edge of the short guide plates to the upper end face of the turntable is higher than the height of the bobbin sleeve 6 and smaller than the cylindrical diameter of the bobbin sleeve; the transverse discharging channel is fixed outside the circumferential discharging hole in a mode that the discharging hole is inclined downwards, a plurality of hollow holes 44 which are connected with semicircular sheets 43 are formed in the bottom plate of the transverse discharging channel, the extending length of the semicircular sheets 43 is larger than the radius of the bobbin case, and a second transverse discharging channel 42 is fixed below the transverse discharging channel.
The conical discharging screw rod slowly rotates to drive the shuttle core sleeve to fall onto the rotary table from the bottom discharging hole of the funnel-shaped storage bin, the horizontal rotation of the rotary table drives the shuttle core sleeve to be conveyed towards the short guide plate along the long guide plate under the action of centrifugal force, the lower end edge of the short guide plate is higher than the height of the shuttle core sleeve 6 and smaller than the cylindrical diameter of the shuttle core sleeve, so that when the dome of the shuttle core sleeve faces upwards or downwards in an upright state, the shuttle core sleeve in a lateral mode, which is distributed horizontally in the dome, can enter the transverse discharging channel through the circumferential discharging hole, is pushed out of the circumferential discharging hole by the rotary table due to the fact that the cylindrical diameter is larger than the distance between the lower end edge of the short guide plate and the upper end face of the rotary table, the lateral shuttle core sleeve and the short guide plate collide to form an upright mode, and then the shuttle core sleeve is conveyed to the circumferential discharging hole by being abutted against the long guide plate again under the action of the centrifugal force of the rotation of the rotary table and the friction force between the rotary table.
The horizontal discharging channel is connected with the circumferential discharging hole, the shuttle core sleeve enters the horizontal discharging channel, and the horizontal discharging channel is obliquely fixed on the frame, so that the shuttle core sleeve slides towards the direction of the discharging hole under the action of gravity.
The horizontal discharging channel is provided with a hollowed-out hole, the hollowed-out hole is formed by a plurality of continuous semicircular sheets, the extending length of each semicircular sheet is larger than the radius of the shuttle core sleeve, the shuttle core sleeve reaches the hollowed-out hole, the shuttle core sleeve with the dome downwards can pass through the hollowed-out hole, the shuttle core sleeve with the dome upwards provided with the bottom downwards is turned over along the semicircular sheets under the action of gravity to fall onto the second horizontal discharging channel, and the shuttle is in a state with the dome downwards after turning over.
The bobbin case on the lateral discharge passage and the second lateral discharge passage therebelow is conveyed to the next sewing machine assembly process in a state with the dome facing downward.
