DETAILED DESCRIPTION

[0021] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0022] refer to Figures 1 to 4

[0023] A yarn drum sequential lifting mechanism comprises a frame, a transverse conveyor belt 10 is arranged on the frame, a top plate 20 is arranged on the upper side of the transverse conveyor belt, a conveying channel 21 of a yarn drum moving seat is formed between the top plate and the conveyor belt, a limiting guide groove 22 is arranged on the top plate for avoiding the boss 1a of the yarn drum moving seat 1, a sequential blocking and releasing mechanism 30 of the yarn drum moving seat is arranged on the conveying channel, and a clamping mechanism 40 for lifting the yarn drum upward is arranged on the upper side of the sequential blocking and releasing mechanism, so that the yarn drum moving seat is blocked and released one by one by the sequential blocking and releasing mechanism, and then the yarn drum 2 on the yarn drum moving seat is lifted and clamped upward by the clamping and releasing mechanism.

[0024] In this embodiment, the sequential blocking and releasing mechanism includes a Y-shaped rod 31 arranged on one side of the conveying channel and the fork rod end extends to the upper side of the transverse conveyor belt, and the two fork rod ends of the Y-shaped rod are correspondingly hinged with a release dial wheel 32 and a blocking dial wheel 33, and the middle part of the Y-shaped rod is hinged with the frame, and the frame is hinged with a horizontal cylinder 34, and the telescopic rod of the horizontal cylinder is hinged with the support rod of the Y-shaped rod. Therefore, the Y-shaped rod is driven by the horizontal cylinder to swing around the hinge point in the middle to achieve the blocking and releasing actions of the yarn reel moving seat.

[0025] The initial state is that the release dial wheel 32 swings toward the side of the transverse conveyor belt 10, the blocking dial wheel 33 extends toward the groove 22, and the horizontal cylinder 34 contracts; because the groove 22 limits the boss 1a of the yarn reel moving seat 1, the bottom disk of the input yarn reel moving seat 1 is blocked by the blocking dial wheel 33 and cannot be output; the clamping machine 40 is activated to clamp the yarn reel 2 upward; the horizontal cylinder 34 extends out, the Y-shaped rod 41 swings, the blocking dial wheel 33 swings toward the side of the transverse conveyor belt 10, the release dial wheel 32 swings toward the groove 22 and pushes the yarn reel moving seat 1 to move in the output direction, thereby releasing the yarn reel moving seat 1, and at the same time, the release dial wheel 32 also blocks the next input yarn reel moving seat 1; the horizontal cylinder 34 contracts, and the Y-shaped rod 31 is reset.

[0026] In this embodiment, in order to better block the yarn reel moving seat, notches 23 are provided on both sides of the groove located at the position of the sequential blocking and releasing mechanism on the top plate, and limiting baffles 24 are provided at the ends of the notches, and the middle part of the limiting baffles is concave to reduce the gap.

[0027] In this embodiment, in order to better block the yarn drum moving seat and reduce the friction between the yarn drum moving seat and the transverse conveyor belt when it is blocked, a horizontally installed suction pipe 35 is installed on the notch away from the blocking release mechanism. The suction pipe is provided with a one-way throttle valve, and the lower side of the suction pipe is provided with a suction hole. Thus, air is sucked upward through the suction pipe, providing an upward suction force for the yarn drum moving seat, thereby reducing the friction between the yarn drum moving seat and the transverse conveyor belt.

[0028] In this embodiment, the top plate is provided with matching infrared photoelectric switches 25 on both sides of the grooves at the positions of the sequential blocking and releasing mechanisms, and the infrared photoelectric switches are electrically connected to the driving mechanisms away from the blocking and releasing mechanisms and the clamping and conveying mechanisms through the controller. There are two pairs of infrared photoelectric switches.

[0029] When the signals of the two pairs of infrared photoelectric switches are blocked at the same time, it means that the yarn reel moving seat enters the blocking and releasing mechanism, and the clamping mechanism operates to clamp the yarn reel upward; when the yarn reel is detached from the yarn reel moving seat, only the signal of the infrared photoelectric switch on the upper side is connected, and the blocking and releasing mechanism releases it; when the yarn reel moving seat is detached from the blocking and releasing mechanism, the signals of the two pairs of infrared photoelectric switches are connected, and the blocking and releasing mechanism returns to the blocking state.

[0030] In the present embodiment, in order to clamp the yarn reel upward, the clamping mechanism includes a vertical conveyor belt 41 whose top is hinged to a vertical frame body 42 arranged on the frame, and a swing plate 43 located on the longitudinal front side of the vertical conveyor belt is hinged on the vertical frame body, and a clamping wheel 44 is rotatably connected to the bottom of the swing plate. The vertical frame body is provided with a driving mechanism for driving the vertical conveyor belt and the clamping wheel to swing towards each other for clamping the yarn reel upward, and a pressure cover 45 is installed on the swing plate to press the yarn reel onto the vertical conveyor belt for transportation as the swing plate swings.

[0031] In this embodiment, the driving mechanism includes a rotating rod 47 driven by a motor 46 in the middle, and the two ends of the rotating rod are respectively hinged with one end of a conveyor belt swing arm 48 and a pinch wheel swing arm 49, and a swing rod 411 is vertically fixed to the side of the vertical conveyor belt, and the other end of the conveyor belt swing arm is hinged with the lower part of the swing rod, and the other end of the pinch wheel swing arm is hinged with the swing plate. Thus, the lower part of the vertical conveyor belt and the pinch wheel can be swung toward or away from each other by the forward and reverse rotation of the motor.

[0032] In this embodiment, the vertical conveyor belt is wound around two pulleys 412, the pulley at the top is driven to rotate via a driving motor 413, and the upper and lower ends of the swing arm are respectively connected to the rotating shafts where the two pulleys are located.

[0033] In this embodiment, in order to drive the pressure cover to swing synchronously and press the yarn reel onto the vertical conveyor belt for transportation, a pair of parallel and obliquely arranged connecting rods 431 are fixed in the swing plate, and the lower ends of the connecting rods are fixedly connected to the front side of the pressure cover respectively.

[0034] In this embodiment, the cross-section of the pressure cover is arc-shaped, and a wear-resistant layer is provided on the inner side of the pressure cover to improve wear resistance and reduce damage to the yarn reel; a guide portion 451 extending obliquely and in an open shape is provided at the lower end of the pressure cover, so as to better guide the yarn reel.

[0035] In this embodiment, the vertical frame is further provided with an upper cover plate 50 which is located on the upper side of the pressure cover and cooperates with the vertical conveyor belt to press the yarn reel onto the vertical conveyor belt for transportation.

[0036] In this embodiment, the vertical frame is installed with a longitudinal plate 421, and a pair of vertical conveyor belts and swing limit plates 422 of the swing plate are installed on the longitudinal plate, so as to limit the swing of the vertical conveyor belts and the swing plate.

[0037] In this embodiment, the vertical frame is provided with a clearance opening 423 for the conveyor belt swing arm to connect with the swing rod and to swing and transfer.

[0038] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0039] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0040] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.
