Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, specifically to an auxiliary yarn unloading and transfer device for an airflow machine. Background Technology

[0002] Air-jet spinning machines, also known as rotor spinning machines, are spinning equipment that directly spins fiber slivers into cones. They use high-speed rotating spinning cups to twist the yarn and then directly wind the yarn into cones of a specified size and shape. After the air-jet spinning machine completes the winding, the cones usually fall off the machine automatically or are removed by the operator.

[0003] In the existing production process, the falling yarn cones usually fall directly into the collection baskets, trays, or on the ground below, or are caught directly by operators next to the machine. Subsequently, operators need to manually move and stack the yarn cones onto a dedicated yarn cart or tray, and then transfer them to the subsequent inspection, weighing, or packaging stations.

[0004] This traditional method has the following technical problems: First, manual unloading, handling, and stacking of yarn is labor-intensive, and the efficiency of the operation is limited by the speed of personnel operation, which restricts the efficiency of the entire production line. Secondly, during multiple manual handling and intermediate transfers, the yarn is prone to problems such as bobbin collisions, yarn deformation, or surface contamination with oil and dust, which affect the appearance quality and grade of the product. Furthermore, the extensive use of yarn carts, pallets, and other transfer equipment not only occupies production space, but also incurs maintenance, wear and tear, and management costs.

[0005] To address the aforementioned technical problems, an auxiliary yarn unloading and transfer device for airflow machines was designed. Summary of the Invention

The drive assembly is fixedly mounted on the frame assembly and is connected to the conveyor shaft for driving the conveyor belt to rotate. The sensing control component includes a bobbin sensor disposed on the conveying component. The bobbin sensor is electrically connected to the driving component and is used to detect whether there is bobbin on the conveying component, and to control the start and stop of the driving component according to the detection signal.

[0008] Preferably, the inclined guide surface of the receiving component is also provided with a yarn bobbin stop to prevent the yarn bobbin from rolling off.

[0009] Preferably, the conveying assembly further includes conveyor belt baffles disposed on both sides of the conveyor belt, and the yarn package sensor is mounted on the conveyor belt baffles.

[0016] Preferably, the main structural components of the frame assembly and the supporting assembly are made of aluminum alloy.

[0017] Beneficial effects This invention provides an auxiliary yarn unloading and transfer device for air-jet printers. By adding a conveyor device with sensor control, this invention achieves continuous and automated transfer of yarn packages from the air-jet printer to the packaging station. This structure eliminates the manual unloading, stacking, and short-distance transport using transfer vehicles required in the original process, directly reducing the workload of operators. Simultaneously, by reducing the number of manual handling and intermediate storage operations, it significantly reduces the risk of surface damage or deformation of the yarn packages due to impacts during multiple transfers, as well as the possibility of contamination from contact with different carriers or environments, thus contributing to maintaining stable product quality. Furthermore, this device reduces the reliance on and frequency of use of numerous turnover tools such as yarn carts, pallets, and mats on the production floor, thereby reducing the daily loss and maintenance costs of these auxiliary materials and simplifying on-site management.

[0027] In this embodiment, the support structure 5 includes a support column for supporting the inclined guide surface 1, the first water platform 4, and the second water platform 11, and the moving mechanism 6 is a caster wheel installed at the bottom of the support column.

[0029] This embodiment is further configured to include a control switch 12 disposed on the second water platform 11, the control switch 12 being electrically connected to the drive component and used for manually controlling the start and stop of the device.

[0030] In this embodiment, the main structural components of the frame assembly and the supporting assembly are made of aluminum alloy.

[0031] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0032] Example: This example provides an auxiliary yarn unloading and transfer device for an airflow machine, the overall structure of which is a movable conveying device. The device includes a frame assembly made of aluminum alloy profiles, the frame assembly being composed of multiple vertical support columns 5 forming the main body. The bottom of the support columns 5 is equipped with four casters 6 with braking function, allowing the entire device to move and be positioned flexibly according to production needs.

[0033] One end of the frame assembly is equipped with a receiving component for connecting to the doffing port of the air-jet spinning machine. This receiving component includes a forward-sloping, downward-inclined aluminum alloy guide surface 1, with its high end connecting to the air-jet machine outlet and its low end connecting to the subsequent horizontal conveying section. Guide baffles 3 are provided on both sides of the inclined guide surface 1 to prevent yarn bobbins from falling off. Multiple parallel yarn bobbin stops 2 can also be provided on its surface to slow the speed of the falling yarn bobbins and prevent them from colliding with each other.

[0034] The lower end of the inclined guide surface 1 is smoothly connected to a horizontal conveying assembly. The conveying assembly mainly consists of a horizontal conveying platform, which can be considered as a first horizontal platform 4 and a second horizontal platform 11 arranged sequentially along the conveying direction for ease of description. At the front and rear ends of the first horizontal platform 4 and the second horizontal platform 11, two conveying shafts 16 are respectively installed via bearings and shaft support columns 10. A closed-loop conveyor belt 8 (e.g., a flat belt or synchronous belt made of rubber or PVC) is wrapped around the two conveying shafts 16 to form the conveying working surface. Conveyor belt baffles 9 are installed on both sides of the conveyor belt 8 to prevent the yarn from slipping off the sides during conveying.

[0035] The drive assembly of the device, mounted on the second platform 11, includes a motor 14. The output shaft of the motor 14 is connected to one of the conveyor shafts 16 (e.g., the main drive shaft located at one end of the second platform 11) via a motor belt 15 (i.e., the first transmission mechanism, which can be a V-belt or a flat belt). The two conveyor shafts 16 are connected by a conveyor belt drive belt 13 (i.e., the second transmission mechanism, typically a synchronous belt), thereby achieving power transmission and synchronous operation between the two shafts. A manual control switch 12 is also mounted on the second platform 11 for controlling the power supply to the entire device.

[0036] One of the core improvements of this invention is the installation of a sensing control component. Specifically, a yarn bobbin sensor 7 (such as a photoelectric sensor or proximity switch) is installed on the conveyor belt baffle 9 near the outlet of the inclined guide surface 1. This sensor 7 is electrically connected to the drive assembly (specifically, the motor 14 or its controller).

[0037] The working principle and operation of the device are as follows: During operation, push the device under the air-jet spinning machine, aligning the high end of the inclined guide surface 1 with the yarn feed port of the air-jet machine. When the air-jet machine finishes spinning and the yarn falls, it first rolls smoothly along the inclined guide surface 1 to the starting end of the conveyor belt 8. When the yarn reaches the conveyor belt 8, it is detected by the yarn sensor 7. The sensor 7 then sends a signal to trigger the drive assembly to start. The motor 14 drives the conveyor shaft 16 to rotate via belt drive, thereby driving the conveyor belt 8 to start working. The conveyor belt 8 automatically and smoothly transports the yarn to the packaging platform (which can be the inlet of an automatic packaging machine or a manual packaging platform) at the other end of the device. When all the yarn on the conveyor belt 8 has been transported, if the sensor 7 does not detect a new yarn after a set delay, it will control the drive assembly to stop running, realizing automatic start and stop and saving energy.

[0038] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
