as shown in fig. 1-6, the invention provides a cloth feeding and end cover discharging device of a through-flow end cover, and the feeding and discharging device adopting a feeding and discharging manipulator further comprises a slideway 5, a feeding and discharging manipulator and a cooling placing tool 6. The through-flow end cover consists of a cloth of a metal piece and an end cover fan blade of an injection molding piece, and the cloth is generally filled into an injection mold, and then the cloth and the injection mold are injection molded at one time through insert injection molding without assembly. The openings of the injection molding equipment for loading the cloth and taking out the end cover are lateral openings, and the cloth feeding device 1 and the cooling placing tool 6 corresponding to the feeding and discharging mechanism are horizontally arranged with the cloth and the end cover.

The cooling placement tool 6 comprises two cylindrical support cylinders which are matched with the opening parts of the through-flow end covers, and the cylindrical support cylinders are arranged on one side of the feeding end of the slideway 5 along the X-direction track direction. The slide way 5 is provided with a gate-shaped support in the front area of the feeding end of the slide way, a plurality of flexible plastic sheets are arranged on the gate-shaped support, one or more layers of flexible plastic sheets can be arranged on the flexible plastic sheets, and the slide way passes through the gate-shaped support when the through-flow end cover is discharged, and then slides downwards after being blocked by the flexible plastic sheets, so that the sliding speed of the through-flow end cover is reduced, the phenomenon that a finished product of the through-flow end cover collides with a storage box or other objects at the discharging end strongly due to the fact that the speed is too fast is avoided, the product is damaged, and the safety of the product is protected.

The feeding and discharging manipulator comprises an feeding and discharging guide rail 2, a lifting mechanism 3 and a grabbing mechanism 4, wherein an X-direction track of the feeding and discharging guide rail 2 passes through injection molding equipment, a cooling placement tool 6, a feeding end of a slideway 5 and a position above a cloth feeding device 1. The grabbing mechanism 4 comprises a rotating mechanism 41, a rotating mounting plate 42, a cloth grabbing mechanism 43 and an end cover grabbing mechanism 44, wherein the rotating mechanism 41 is arranged at the lower end of a mechanical arm of the lifting device, the rotating mounting plate 42 is fixed on a rotatable piece of the rotating mechanism 41, the cloth grabbing mechanism 43 and the end cover grabbing mechanism 44 are arranged on the rotating mounting plate 42, the cloth grabbing mechanism 43 is arranged between the rotatable piece and the end cover grabbing mechanism 44, a gap for accommodating a cloth top ring piece is formed in the center of the cloth grabbing mechanism 43, and the cloth grabbing mechanism 43 comprises a plurality of cloth sucking discs capable of sucking a cloth bottom disc.

The cloth feeding and end cover discharging device of the through-flow end cover comprises a spiral feeding disc, a feeding track 14, an ejection mechanism 18 and a separation mechanism 15. The spiral feeding tray comprises a base 11, a driving device arranged in the base 11, a barrel 12 fixed on the base 11, and a spiral feeding track 13 arranged in the barrel 12 and in transmission connection with the driving device at the center, wherein the top discharge end of the feeding track passes through the feeding end of the feeding track 14 in rotation, two symmetrical L-shaped guide plates 141 are fixed on the feeding track 14, the horizontal part of each L-shaped guide plate 141 is positioned on the upper part, the distance between the horizontal parts of the two L-shaped guide plates 141 is matched with the width of a ring piece at the top of a cloth, and the gap height of each L-shaped guide plate 141 and the feeding track 14 is matched with the height of a disc at the bottom of the cloth. Thus, if the cloth which is delivered to the feeding end of the feeding track 14 is in an inclined or inverted state, the cloth cannot enter the channel formed by the two L-shaped guide plates 141, and the cloth entering the feeding track 14 can be regulated. The drive means may be an electric motor or other structural power means such as a rotary cylinder.

The top discharge end of the spiral feeding track 13 is provided with a slope 131 which is convenient for the cloth to slide inwards, the inclined angle of the slope 131 is smaller than 30 degrees, and the width is smaller than 1/4 of the diameter of the bottom of the cloth. Thus, when irregular cloth reaches the feeding hole of the feeding track 14 and is blocked by the L-shaped guide plate 141, the movable slope 131 slides into the spiral feeding track 13 to be ready to be sent to the feeding track 14 next time. The inclination angle of less than 30 degrees and the width of less than 1/4 of the diameter of the bottom of the cloth are both intended to prevent the cloth, the bottom of which is in contact with the screw feed rail 13, from slipping off during the latter transport.

A conveyer belt is arranged at the bottom of the feeding track 14. The cloth was transported to the feed end. The discharge end of the feeding rail 14 is provided with a positioning groove 16, the end part of the positioning groove 16 is semicircular corresponding to the shape of the cloth, the bottom of the positioning groove 16 is provided with a through hole 161, the ejection mechanism mounting plate 17 is fixed on the outer side wall of the square edge part of the cylinder 2 provided with the feeding rail 14, and the ejection mechanism mounting plate is provided with a hole corresponding to the through hole 161 for the extending end of the ejection mechanism 18 to pass through. The ejection mechanism 18 is an electric cylinder fixed at the bottom of the discharge end of the feeding track 14, and is installed below an ejection mechanism installation plate 17 positioned at the bottom of the discharge end. The piston rod of the electric cylinder extends out of the end and is provided with a thimble 181 corresponding to the central concave hole at the bottom of the cloth, and the thimble 181 is positioned at the center of the through hole 161. Thus, the cloth in the positioning groove 16 can be lifted to a position suitable for grabbing by the feeding and discharging mechanical arm under the action of the ejection mechanism 18, so that the ejection mechanism can greatly facilitate the arrangement and grabbing of the mechanical arm, and the universality and the convenience degree of the invention are improved.

A separation mounting plate is fixed on the outer side of the feeding track 14, and the separation mechanism 15 and the photoelectric sensor 19 are fixed on the separation mounting plate. The separation mechanism 15 comprises a shell 151, a rotary air cylinder 154, two connecting rods 152 and two stop rods 153, wherein the rotary air cylinder 154, the two connecting rods 152 are arranged in the shell 151, the two ends of each connecting rod 152 are respectively hinged with a rotating part 155 of the rotary air cylinder 154 and one inward end of each stop rod 153, each stop rod 153 extends to the upper surface of the feeding track 14, the stop rods 153 extend to block a ring piece at the top of the cloth, and when the stop rods 153 retract, the cloth passes through the ring piece. The rotating part 155 drives the two stop rods 153 under the action of the rotating cylinder 154 to realize the requirement that one stop rod 153 extends and the other stop rod 153 retracts.

The photoelectric sensor 19 is arranged at the discharge end of the feeding track 14, and the separation mechanism 15 is arranged in front of the discharge end of the feeding track 14. The photo-sensor 19 is electrically connected to the partition mechanism 15 and the ejection mechanism 18. The controller is electrically connected with the photoelectric sensor 19, the conveyor belt and the driving device in the base 11 respectively.

The working procedure of each of the above embodiments is as follows: a plurality of toasts are poured into the barrel body 12, and the toasts are conveyed upwards to the feeding end of the feeding track 14 in the process that the spiral feeding track 13 rotates along with the driving device. If the cloth is in a shape with the bottom facing downwards and accords with the feeding rule, the cloth can move forwards under the action of the conveying belt through the feeding track 14; otherwise caught by the ends of the L-shaped guide plate 141 and will slip off the ramp 131 due to the irregular state of the cloth with its top disc itself in an inclined unstable state. When the photoelectric sensor 19 at the discharge end of the feeding track 14 senses that the ring piece at the top of the cloth is passed through the positioning groove 16, a signal is sent to make the ejection mechanism 18 operate to jack up the cloth in the positioning groove 16, meanwhile, the separation mechanism 15 receives the signal of the photoelectric sensor 19 and stretches out the stop lever 153 close to the positioning groove 16, so that other cloth is prevented from entering the positioning groove 16, and meanwhile, the stop lever 153 far away from the positioning groove 16 is retracted, so that the next cloth enters the feeding track 14 at the position of the separation mechanism 15.

When the waiting interval time is up, the ejected cloth is taken away by the feeding and discharging mechanical arm, the feeding mechanism is reset, the stop lever 153 close to the positioning groove 16 is retracted when the photoelectric sensor 19 cannot detect the cloth, and the other stop lever 153 extends. The cloth originally at the separating mechanism 15 enters the positioning groove 16 under the action of the conveyor belt, but the rear cloth is blocked by the stop lever 153 from entering the feeding rail 14 at the separating mechanism 15. The previous flow of ejector mechanism 18 and separator mechanism 15 is repeated until the passage of cloth is detected by photo sensor 19. During feeding, the spiral feeding track 13 and the conveyor belt always run at equal intervals or at equal speeds according to the instructions of the controller. If the controller finds that the signal sent by the photoelectric sensor does not accord with the normal signal standard, the abnormal condition is indicated, the spiral feeding track 13 and the conveyer belt can stop working and warn an operator, and production accidents are prevented.
