Description

Technical Field

[0001] The utility model relates to the technical field of yarn bobbin grasping and placing, and specifically discloses a yarn bobbin grasping and placing device. Background Technique

[0002] As a key component in textile machinery, the yarn bobbin undertakes the tasks of winding and transporting the yarn. The grasping and placing operations of the yarn bobbin directly affect the efficiency of textile production and the quality of the yarn. Therefore, optimizing the yarn bobbin grasping and placing technology is of great significance for improving the production efficiency of textile enterprises. The traditional yarn bobbin grasping and placing operations are mainly completed manually, with problems such as low efficiency and high labor intensity. In modern textile machinery, automated and intelligent yarn bobbin grasping and placing devices are generally adopted, greatly improving the production efficiency and operation accuracy.

[0003] The yarn bobbin grasping and placing device usually consists of parts such as a robotic arm, a gripper, and a control system. The robotic arm is responsible for moving the gripper to the specified position, and the gripper is responsible for grasping and releasing the yarn bobbin. The control system is responsible for controlling the actions of the robotic arm and the gripper to ensure that the yarn bobbin can be accurately and quickly grasped and placed. For example, the yarn feeding device for a winding machine disclosed in the patent with publication number CN110482323B includes a rotary lifting mechanism and a grasping mechanism, and the grasping mechanism is installed at the movable end of the rotary lifting mechanism, and the movable end of the rotary lifting mechanism can rotate while lifting.

[0004] In the above solution, when the yarn bobbin is placed, the pneumatic finger cannot put the thread end into the through hole in the middle of the yarn bobbin, and the above actions still need to be completed manually, resulting in low efficiency of yarn bobbin placement. Content of the Utility Model

[0005] Aiming at the above deficiencies of the prior art, the utility model provides a yarn bobbin grasping and placing device to solve the problem that when the yarn bobbin is placed, the pneumatic finger cannot put the thread end into the through hole in the middle of the yarn bobbin, and the above actions still need to be completed manually, resulting in low efficiency of yarn bobbin placement.

[0006] To achieve the above object, the technical solution of the utility model is as follows:

[0007] A yarn bobbin gripping and releasing device includes a bottom plate, and a number of yarn bobbin clamps are arranged along the circumferential direction at the edge of the bottom plate; a thread clamp is arranged on each yarn bobbin clamp; the yarn bobbin clamp is provided with a first through hole along the axial direction; the thread clamp includes a nozzle; the nozzle is hermetically arranged at the upper open end of the yarn bobbin clamp; a second through hole is arranged in the middle of the nozzle; a positive pressure air port is arranged along the radial direction on the side wall of the nozzle; the inner diameter of the lower opening of the second through hole is smaller than the inner diameter of the through hole in the middle of the yarn bobbin. When gripping the yarn bobbin, the first through hole of the yarn bobbin clamp and the second through hole of the nozzle can be externally connected to a pipeline for air extraction, so as to suck the yarn bobbin into the yarn bobbin clamp and suck the thread into the thread clamp; when releasing the yarn bobbin, an air source is externally connected to the positive pressure air port, so that the yarn bobbin can be placed in the yarn storage library, and the thread in the thread clamp can be blown into the through hole in the middle of the yarn bobbin, avoiding manual operation and improving the efficiency of yarn bobbin placement. The setting that the inner diameter of the lower opening of the second through hole is smaller than the inner diameter of the through hole in the middle of the yarn bobbin ensures that the thread extracted in the second through hole can be blown into the through hole in the middle of the yarn bobbin again.

[0008] Preferably, the yarn bobbin gripping and releasing device further includes an air collecting chamber; the bottom surface of the air collecting chamber communicates with two nozzles; an air extraction pipe is arranged in the middle of the top surface of the air collecting chamber. Two yarn bobbins can be extracted at one time, further improving the efficiency of yarn bobbin placement.

[0009] Preferably, the yarn bobbin clamp includes a fixed seat; a sleeve is fixedly arranged on the fixed seat; a bell mouth is arranged at the bottom surface of the fixed seat through bolts; a connecting cover is arranged at the top surface of the fixed seat through bolts; a fixed pipe is arranged in the middle of the top surface of the connecting cover; the nozzle is arranged on the fixed pipe. The setting of the bell mouth facilitates guiding the yarn bobbin into the sleeve of the fixed seat; the setting of the fixed pipe facilitates the fixation of the nozzle.

[0010] Preferably, a silica gel sleeve is arranged in the sleeve; the axial length of the silica gel sleeve is longer than the length of the sleeve. During use, the upper and lower ends of the silica gel sleeve extend out of the sleeve and are turned over, and then the silica gel sleeve is fixed by the bell mouth and the connecting cover. The setting of the silica gel sleeve increases the friction with the yarn bobbin and facilitates sucking up the yarn bobbin by using an external air source.

[0011] Preferably, a gas guiding nozzle is arranged in the upper part of the inner cavity of the nozzle; the gas guiding nozzle is integrally arranged in a circular tube shape; an annular groove is arranged on the outer wall of the gas guiding nozzle; a number of communication holes are uniformly arranged along the circumferential direction on the bottom surface of the gas guiding nozzle; the communication holes communicate the annular groove and the second through hole of the nozzle; the annular groove communicates with the positive pressure air port; an interference fit is provided between the outer wall of the nozzle and the fixed pipe. While ensuring the air extraction of the thread clamp and the yarn bobbin clamp by the air collecting chamber, when blowing air at the positive pressure air port, the air flow can be guided from the nozzle to the connecting cover, avoiding blowing into the air collecting chamber, ensuring the smoothness of air flow blowing and ensuring the thread placement.

[0012] Preferably, a filter screen is arranged in the air collecting chamber; the filter screen is arranged at the connection between the nozzle and the air collecting chamber. The thread can be restricted at the gas guiding nozzle, facilitating the thread to be blown into the through hole in the middle of the yarn bobbin again by the air blown from the positive pressure air port.

[0013] The beneficial effects of the present utility model are as follows: When grasping the yarn tube, the first through hole of the yarn tube clamp and the second through hole of the nozzle can be externally connected to a pipeline for air extraction, sucking the yarn tube into the yarn tube clamp and sucking the thread end into the thread end clamp; when placing the yarn tube, connecting an air source to the positive pressure air port can place the yarn tube in the yarn storage bin and blow the thread end in the thread end clamp into the through hole in the middle of the yarn tube, avoiding manual operation and improving the efficiency of yarn tube placement.
