Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a material tray rotation device for a bobbin and bobbin case delivery device for an embroidery machine. Background Technology

[0002] When the embroidery machine is working, it has multiple embroidery stations spaced apart in the X direction and feeds the fabric in the Y direction to perform batch embroidery processing on a large area of ​​fabric. After the embroidery is completed, the entire piece of fabric is cut according to the needs of subsequent processing to improve the efficiency of embroidery processing. Therefore, each embroidery station in the X direction of the embroidery machine is provided with a bobbin and bobbin case mounting position for supplying embroidery thread. The bobbin and bobbin case for winding embroidery thread are inserted and fixed in the Y direction inside the mounting position.

[0003] In existing technologies, bobbin and bobbin case replacement in multiple stations of embroidery machines is mostly performed using thread-changing robots.

[0004] For example, the applicant's first-generation product: CN2024225364398 - A multi-station bobbin and bobbin case replacement and delivery device for an embroidery machine, including a power supply guide rail and a three-axis delivery unit; wherein the top of the power supply guide rail is slidably connected to the three-axis delivery unit, the middle of the power supply guide rail supplies power to the brushes of the three-axis delivery unit through conductive copper sheets, and a rack is embedded on one side of the lower part of the power supply guide rail and is fixedly supported in the Z and Y directions to provide translational force for the three-axis delivery unit; the three-axis delivery unit includes a dual-axis robotic arm and a translational tray, the gripping end of the dual-axis robotic arm and the translational tray cooperate in a three-axis manner to replace and deliver bobbins and bobbin cases at the workstation of the embroidery machine. This device aims to improve the positioning and gripping accuracy of the robotic claw relative to the bobbin and bobbin case, and effectively increases the load-bearing capacity of the bobbin and bobbin case within the device, while reducing the force load on the power supply guide rail of the overall device, thereby solving the problems of poor positioning accuracy and low delivery efficiency of bobbin and bobbin case delivery devices in the prior art.

[0005] For example, the applicant's second-generation product, CN2025203521485, discloses a delivery device for bobbin and bobbin case of an embroidery machine. This delivery device includes a power supply rail and a three-axis delivery unit. The three-axis delivery unit includes a Z-shaped translation plate, a dual-axis robotic arm, and a translation tray. A Y-direction extending bend is integrally formed in the middle of the translation plate, which is X-directionally slidably fastened to the top and side wall of the power supply rail. The translation tray is X-directionally slidably supported on the side wall of the translation plate above the power supply rail. A dual-axis robotic arm, capable of Z-direction lifting and Y-direction extension and retraction, is arranged on the side wall of the translation plate to grasp the bobbin and bobbin case on the translation tray. A main power motor, brushes, and electronic control components are arranged on the side wall of the translation plate to the side of the power supply rail. Compared to the applicant's previous generation product, this device has a higher integration level, shortens the overall length of the coaxial transmission connection between the motor and the screw, and brings the overall center of gravity of the three-axis delivery unit closer to the power supply rail, reducing the lateral load on the power supply rail.

[0006] The above products all use a flat translation tray to mount the bobbin and bobbin case, which differs from this application as follows: Figure 5 As shown, in the first-generation and second-generation products, when the material tray delivers bobbins and bobbin cases from the leftmost station to the rightmost station, the X-axis power unit needs to drive the material tray to translate a distance D. However, in this application, since the material tray can rotate and translate, it only needs to translate a distance d to remove all bobbins and bobbin cases from the material tray. Compared with the first-generation and second-generation products, it is more suitable for working conditions with limited space and restricted material tray translation distance. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a material tray rotation device for the bobbin and bobbin case delivery device of an embroidery machine. This material tray rotation device enables the rotating material tray to have X-axis translation and XZ vertical plane rotation functions, shortening the translation distance of the rotating material tray when the robot arm picks up the bobbin and bobbin case, further reducing the adverse effects of space constraints on the operation of the bobbin and bobbin case delivery device, and the structure is simple and easy to implement.

[0008] Therefore, this utility model proposes a material tray rotation device for a bobbin and bobbin case delivery device for an embroidery machine, defining the arrangement direction of the workstations on the embroidery machine as the X direction, the delivery direction for inserting and removing bobbins and bobbin cases at each workstation as the Y direction, and the direction of gravity as the Z direction.

[0009] The tray rotation device is arranged on the translation plate of the three-axis delivery unit. The tray rotation device includes a window plate, a rotating tray, a rotating tray, an X-axis power unit, and a rotation power unit.

The rotating tray is circumferentially and radially limited and axially pluggable to a rotating material tray on the side of the rotating tray facing away from the embroidery machine. The rotating power unit provides rotational power to the side of the rotating tray facing the embroidery machine.

[0011] Preferably, the X-axis power unit includes an X-axis motor, an X-axis screw, and an X-axis translation block. The X-axis motor is fixed on the side of the translation plate facing the embroidery machine, and the power output end of the X-axis motor is coaxially fixed to the X-axis screw. The X-axis screw is threadedly connected to the X-axis translation block, one side of which slides against a Y-axis side of the translation plate facing the embroidery machine. The top of the X-axis translation block extends Y-axis through the translation clearance window and is fixedly connected to the window plate.

[0012] Preferably, the rotary power unit includes a rotary motor and a transmission belt, wherein the rotary motor is fixed on the side of the window panel facing away from the embroidery machine, and the power output end of the rotary motor and the power output end of the rotary tray are both rotated and inserted into the side of the window panel facing the embroidery machine and are connected by the transmission belt.

[0014] The advantages and technical effects of this utility model are as follows:

[0015] This utility model discloses a material tray rotation device for a bobbin and bobbin case delivery device for an embroidery machine. Compared to the first and second generation products, it firstly provides clearance through a translational clearance window, and then arranges a rotational power unit on the window plate to provide rotational power for the rotating material tray. This is not limited by the position of the translational plate relative to the rotational power unit during the translation of the window plate. The X-axis power unit provides translational force to the window plate, which in turn provides translational force to the rotating material tray. This allows the rotating material tray to perform coordinated translational and rotational actions during operation, reducing the material tray translation distance D of the first and second generation products to d. Figure 5 As shown.

[0016] This utility model discloses a rotating tray device for delivering bobbin cores and bobbin cases in an embroidery machine. It features a quick and convenient retrieval mechanism for the rotating tray. The tray is positioned and inserted circumferentially and radially by pins on the rotating tray. A magnetic block provides a Y-axis suction force to the tray, thereby enabling the rotating tray to be axially inserted and removed from the rotating tray. This axially insertable and removable function facilitates the replacement of empty rotating trays by operators, thus enabling batch replacement of empty bobbin cores and bobbin cases.
