Description

Technical Field

[0001] The utility model relates to the field of textile equipment, in particular to a simple and efficient bobbin yarn lowering buffer device. Background Art

[0002] As the requirements for the automation level of textile factories are getting higher and higher, the demand for automatic packaging equipment for bobbins is increasing; according to the requirements, the weight deviation of the whole package of bobbins is not allowed to exceed the tolerance, which requires the bobbins to be weighted before the whole package of bobbins is packaged. In order to ensure the efficiency of the fully automatic packaging line, a buffer device is generally set before the bobbins reach the bobbins packaging line to temporarily store bobbins of appropriate weight received from the conveyor line. When the required number of bobbins is gathered, the bobbins on the buffer device flow into the centralized conveyor line for subsequent whole package packaging and palletizing.

[0003] Chinese patent CN112607104A proposes a temporary storage and conveying system for bobbin yarns that are packed immediately after being put down, including a three-dimensional storage unit, an upper yarn conveying line, a lower yarn conveying line and a control unit. The three-dimensional storage unit includes a frame, a yarn basket and a yarn basket driving device. The yarn basket driving device is installed on the inner side of the frame, and the yarn basket driving device is equipped with a power mechanism. There are multiple yarn baskets, and all yarn baskets are arranged on the yarn basket driving device in a regular arrangement. The yarn basket driving device drives all yarn baskets to perform a circular rotation movement in the frame. A yarn inlet pushing mechanism that can transfer the bobbin yarn from the upper yarn conveying line to the yarn basket is arranged above the upper yarn conveying line, and a yarn outlet pushing mechanism that can transfer the bobbin yarn from the yarn basket to the lower yarn long conveying line is arranged above the lower yarn conveying line. The present invention temporarily stores different types of bobbin yarns, has a simpler structure, occupies a small area, is more suitable for the temporary storage of a variety of bobbin yarns, has a high degree of automation, reduces the number of manipulator configurations in the entire conveying process, reduces costs, and greatly improves packaging efficiency.

[0004] Chinese patent CN112830001A proposes a bobbin temporary storage system with a counterweight function. It includes a weighing conveying line, a temporary storage box assembly, and a circular counterweight line; a weighing position is set on the weighing conveying line; a counterweight yarn basket is set on the circular counterweight line; the temporary storage box assembly includes a frame, and a temporary yarn basket is set in the frame; an upper yarn conveying line is set on one side of the frame, and a lower yarn conveying line is set on the other side; a first yarn pushing assembly capable of pushing the bobbin yarn into the counterweight yarn basket on the circular counterweight line is set on the weighing conveying line; a second yarn pushing assembly capable of pushing the bobbin yarn in the counterweight yarn basket onto the upper yarn conveying line is set on the circular counterweight line; an upper yarn assembly capable of pushing the bobbin yarn on the upper yarn conveying line into the temporary storage yarn basket, and a lower yarn assembly capable of pushing the bobbin yarn in the temporary storage yarn basket onto the lower yarn conveying line are set on the frame. The circular design of the circular counterweight line of the present invention and the circular rotation setting of each temporary storage yarn basket in the temporary storage box assembly greatly reduce the floor space occupied by bobbin yarn counterweight and temporary storage.

[0005] The main purpose of the above two patents is to reduce the number of manipulator configurations, reduce costs, and reduce floor space. However, in the actual production process, one temporary storage system corresponds to one or two manipulators, but corresponds to more than 10 cache belts. If the cache belt is full of a bag and subsequent packaging work is carried out, when the manipulator unloads the yarn, multiple cache lines are idle. The efficiency of the manipulator unloading yarn is not enough to quickly fill the cache belts in the conveying system. The multiple belt lines are useless, and the time to enter the cache device will seriously affect production efficiency. If the yarn unloading robot fills the cache belt first, and then unloads the yarn uniformly after more than 10 cache belts are filled with yarn, the packaging machine will be idle for a long time, the work efficiency will be greatly reduced, and the production capacity will be seriously reduced.

[0045] Furthermore, guard rails 6 are respectively provided on both sides of the buffer belt A3 and the buffer belt B4. There are four groups of guard rails 6 to form two bobbin yarn 8 channels. The function of the guard rails 6 is to guide the rolling direction of the bobbin yarn 8 and to correct the position of the bobbin yarn 8.

[0046] The yarn joining mechanism 5 includes a yarn joining plate 51, a support 52, a cylinder 53 and a rotating shaft 54. The support 52 is arranged in the middle of the end of the centralized conveying mounting frame 2 close to the manipulator guide rail 1, and the yarn joining plate 51 is rotatably arranged on the top of the support 52 through the rotating shaft 54; a support plate 55 is arranged on the lower surface of one side of the yarn joining plate 51, the cylinder 53 is arranged on one side of the support 52, and the piston rod end of the cylinder 53 is rotatably connected to the support plate 55; the yarn joining plate 51 rotates around the rotating shaft 54 ​​under the drive of the cylinder 53.

The pair of supporting plates 71 is symmetrically arranged on the driving mechanism 72. The pair of supporting plates 71 is arranged just above the yarn receiving plate 51. The pair of supporting plates 71 can cooperate with the two notches 51a to unload the bobbin yarn 8 on the yarn receiving plate 51. The driving mechanism 72 includes a box, a slide groove arranged on the box and cooperating with the robot guide rail 1, a driving motor and a traction belt arranged on the top of the robot guide rail 1; the driving motor is connected to a roller, one end of the traction belt is fixed on the roller, and the other end is fixed on the box; the driving motor is rotated forward or reversed to drive the yarn unloading robot 7 to move up and down.

[0049] Furthermore, a protrusion 71a is provided on the upper side of the end of the support plate 71 close to the centralized conveying mounting frame 2 to prevent the bobbin 8 from rolling down during the unloading process.

[0050] Furthermore, the lower yarn buffer device of the bobbin yarn 8 also includes a control system, which is connected to the upper computer of the factory to obtain information of other processes and control the operation of various mechanisms of the lower yarn buffer device of the bobbin yarn 8; the control system includes a control chip and a plurality of control buttons, and the control chip is a programmable chip such as a single-chip microcomputer or a PLC controller; the functions of the control system of the utility model can be implemented by those skilled in the art according to the description in this article without creative labor, so the details are not repeated.

[0051] Specifically, the workflow of the utility model is:

[0052] Before the yarn 8 is put into the aerial conveyor line, the weight information of the single yarn 8 is obtained by weighing, and the weight information is recorded through the aerial conveyor line cage information; when the yarn 8 is transmitted on the aerial conveyor line, the whole package of yarn 8 is weighted according to the algorithm. When the yarn 8 of appropriate weight passes the position of the yarn unloading robot 7, the yarn unloading robot 7 moves upward along the robot guide rail 1 to remove the yarn 8 from the aerial conveyor line; the yarn unloading robot 7 moves downward along the robot guide rail 1 with the yarn 8 to the height position of the yarn receiving plate 51; Before arriving, it is determined whether the bobbin yarn 8 is suitable for being placed in the buffer belt A3 or the buffer belt B4 based on the weight information of the bobbin yarn 8. If it is suitable for being placed in the buffer belt A3, the cylinder 53 contracts, the yarn joining plate 51 tilts toward the buffer belt A3, and after the bobbin yarn 8 falls onto the yarn joining plate 51, it rolls toward the buffer belt A3 under the action of gravity; if it is suitable for being placed in the buffer belt B4, the cylinder 53 extends, the yarn joining plate 51 tilts toward the buffer belt B4, and after the bobbin yarn 8 falls onto the yarn joining plate 51, it rolls toward the buffer belt B4 under the action of gravity.

[0053] Under the action of the guard rail 6, the bobbin 8 is helped to adjust its position after rolling into place. After each unloading action is completed, the buffer belt of the bobbin 8 moves forward by a distance of one bobbin 8 until the unloading action of the whole package of bobbin 8 is completed. After the unloading of the whole package of bobbin 8 is completed, the buffer belt transports the bobbin 8 to the centralized conveying belt at one time and enters the baler for the whole package packaging and palletizing. Generally, a baler with a daily packaging capacity of 35 tons can be equipped with 4 to 6 buffer devices.
