[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The following is for reference. Figure 1 and Figure 2 The feeding device 100 according to a first aspect embodiment of the present invention is described.

[0022] like Figure 1 and Figure 2 As shown, the feeding device 100 according to a first aspect embodiment of the present invention includes: a base 10, a control unit, a mounting bracket 20, a position drive component, a plurality of gripping components, and an action drive component 50. For example, there may be two, three, or four gripping components.

[0023] Specifically, the mounting frame 20 is disposed on the base 10, the position drive is adapted to drive the mounting frame 20 to move on the base 10, the position drive is electrically connected to the control unit, the gripper is disposed on the mounting frame 20, the gripper is adapted to grip the fabric, the motion drive 50 and the gripper are both electrically connected to the control unit, the multiple grippers include a first gripper 40 and a second gripper 41, the motion drive 50 is adapted to drive the first gripper 40 and the second gripper 41 to move relative to each other in the horizontal direction.

[0024] The mounting frame 20 can move vertically relative to the base 10, and it can also move horizontally relative to the base 10. Multiple grippers are arranged at intervals. The first gripper 40 can be movably mounted on the mounting frame 20 in the horizontal direction, or the second gripper 41 can be movably mounted on the mounting frame 20 in the horizontal direction, or both the first gripper 40 and the second gripper 41 can be movably mounted on the mounting frame 20 in the horizontal direction.

[0025] During production, when material needs to be fed, the control unit controls the position drive to operate. The position drive drives the mounting component to move above the fabric. Subsequently, the position drive can either drive the mounting frame 20 downward to make the gripper contact the fabric, or the feeding platform 220 supporting the fabric can move upward to make the fabric contact the gripper, or the position drive can drive the mounting frame 20 downward and the feeding platform 220 supporting the fabric upward to make the fabric contact the gripper. After the gripper contacts the fabric, the control unit controls the gripper to grab the fabric. Then, the control unit controls the mounting frame 20 to move upward to detach the fabric from the feeding platform 220, and then controls... The unit control actuator 50 drives the first gripper 40 and the second gripper 41 to move relative to each other in the horizontal direction, increasing the distance between the first gripper 40 and the second gripper 41 to tension the fabric. Then, the control unit controls the mounting frame 20 to move to the set feeding position and causes the grippers to release the fabric. When the size of the fabric being fed by the feeding device changes, the distance the first gripper 40 and the second gripper 41 move relative to each other in the horizontal direction also changes accordingly to adapt to the tensioning requirements of fabrics of different sizes. Thus, automatic feeding of the fabric can be achieved. After feeding is completed, the control unit controls the mounting frame 20 to move back to the initial position.

[0026] According to the first aspect of the present invention, the feeding device 100 can realize automatic feeding of fabric, and during the feeding process, the fabric can be tensioned to make the fabric flat, thereby saving the process of flattening the fabric and thus improving production efficiency.

[0027] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the mounting bracket 20 includes: a first bracket 21 and a second bracket 22. The second bracket 22 is movably mounted on the first bracket 21 along a first direction. A first gripper 40 is mounted on the first bracket 21, and a second gripper 41 is mounted on the second bracket 22. An action drive member 50 is adapted to drive the second bracket 22 to move along the first direction on the first bracket 21. The first direction is perpendicular to the up and down direction.

[0028] During production, when the fabric needs to be tensioned, the actuating drive 50 drives the second support 22 to move along the first direction on the first support 21 to increase the distance between the first gripper 40 and the second gripper 41. In this way, the force of the actuating drive 50 will not directly act on the first gripper 40 and the second gripper 41, and the probability of the first gripper 40 and the second gripper 41 being damaged during operation is low, thereby improving the reliability of the first gripper 40 and the second gripper 41 during operation. Furthermore, in the design of the feeding device 100, the stroke parameters of the first gripper 40 and the second gripper 41 can be adjusted by adjusting the dimensional parameters of the guiding and mating structure of the first support 21 and the second support 22, which can reduce the design difficulty of the feeding device 100.

[0029] In some embodiments of this utility model, the action driving component 50 is a drive motor.

[0030] The first bracket 21 has locking flanges extending inward along the first direction on both sides of its width direction, and the second bracket 22 has locking protrusions extending in the first direction on both sides of its width direction. The locking protrusions are located between the locking flanges and the surface of the first bracket 21 facing the locking flanges. In this way, the locking flanges and locking protrusions can cooperate to connect the second bracket 22 to the first bracket 21 and make the second bracket 22 movable in the first direction.

[0031] A linear motion conversion structure, such as a ball screw connection structure or a gear rack connection structure, is connected between the first support 21 and the second support 22. The motion drive 50 drives the movement of the second support 22 on the first support 21 through the ball screw connection structure or the gear rack connection structure.

[0032] The drive motor has a fast response speed and high motion accuracy. By setting the motion drive component 50 as a drive motor, the feeding efficiency can be improved, and the positional accuracy of the first gripper 40 and the second gripper 41 when tensioning the fabric can be improved, thereby improving the flatness of the fabric.

[0033] In some embodiments of this utility model, such as Figure 2As shown, the feeding device 100 also includes a first detection element 60, which is disposed on the mounting frame 20 and is used to detect the relative position of the first gripper 40 and the fabric. The first detection element 60 is electrically connected to the control unit.

[0034] During the feeding process, the first detection element 60 detects the relative position of the first gripping element 40 and the fabric and transmits the data to the control unit. When the first gripping element 40 contacts the fabric or the distance between the first gripping element 40 and the fabric is less than a set distance, the control unit sends a command to the first gripping element 40 to grip the fabric. This can increase the probability that the feeding device 100 can successfully grip the fabric.

[0035] In some embodiments of this utility model, such as Figure 2 As shown, the feeding device 100 also includes a second detection element 70, which is mounted on the mounting frame 20 and is used to detect the relative position of the second gripper 41 and the fabric. The second detection element 70 is electrically connected to the control unit.

[0036] During the feeding process, the second detection element 70 detects the relative position of the second gripper 41 and the fabric and transmits the data to the control unit. When the second gripper 41 contacts the fabric or the distance between the second gripper 41 and the fabric is less than a set distance, the control unit sends a command to the second gripper 41 to grip the fabric. This can further increase the probability that the feeding device 100 can successfully grip the fabric.

[0037] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the feeding device 100 also includes: a support frame 80, which is movably mounted on the base 10 along a second direction, and a mounting frame 20 is movably mounted on the support frame 80, with the second direction being perpendicular to the vertical direction.

[0038] During the feeding process, the relative positions of the gripper and the fabric in the horizontal direction can be adjusted by moving the support frame 80 in the second direction, and the relative positions of the gripper and the fabric in the vertical direction can be adjusted by moving the mounting frame 20 in the vertical direction. Thus, the processes of gripping and moving the fabric can proceed normally.

[0039] The position adjustment of the gripper in the horizontal and vertical directions is achieved by moving the support frame 80 in the second direction and the mounting frame 20 in the vertical direction. The support frame 80 and the mounting frame 20 will not interfere with each other during the movement, which can simplify the cooperation relationship in the feeding device 100 and reduce the design difficulty of the feeding device 100.

[0040] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the position drive includes a first drive 30 and a second drive 31. The first drive 30 is adapted to drive the support frame 80 to move along a second direction on the base 10, and the second drive 31 is adapted to drive the mounting frame 20 to move along a vertical direction on the support frame 80.

[0041] In other words, the mounting frame 20 and the support frame 80 are driven by separate position driving components, which allows the mounting frame 20 and the support frame 80 to quickly reach the set position, thereby improving the feeding efficiency. Furthermore, the connection structure between the first driving component 30 and the support frame 80, and between the second driving component 31 and the mounting component is relatively simple, which can further simplify the component structure of the feeding device 100 and reduce the design difficulty of the feeding device 100.

[0042] In some embodiments of this utility model, the first driving component 30 is a driving cylinder.

[0043] One of the support frame 80 and the base 10 is provided with a guide rail extending in the second direction, and the other is provided with a slide groove extending in the second direction. The guide rail is fitted into the slide groove to guide and limit the support frame 80.

[0044] The drive cylinder has a simple structure and is easy to arrange. It is understandable that most of the components on the feeding device 100 are supported on the support frame 80. The support frame 80 exerts a large force on the base 10, while the drive cylinder has a large driving force, which can easily meet the driving needs of the support frame 80.

[0045] In some embodiments of this utility model, the second driving component 31 is a drive motor.

[0046] One of the mounting frame 20 and the support frame 80 is provided with a vertically extending guide rail, and the other is provided with a vertically extending slide groove. The guide rail is fitted into the slide groove to guide and limit the mounting frame 20. A linear motion conversion structure, such as a ball screw connection structure or a gear rack connection structure, is connected between the mounting frame 20 and the support frame 80. The second drive member 31 drives the movement of the mounting frame 20 on the support frame 80 through the ball screw connection structure or the gear rack connection structure.

[0047] The drive motor has a fast response speed and high accuracy. By setting the second drive component 31 as a drive motor, the feeding efficiency can be improved and the positional accuracy of the mounting frame 20 can be improved, thereby increasing the probability of successfully grabbing the fabric.

[0048] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the multiple grippers also include a third gripper 42, which is located between the first gripper 40 and the second gripper 41.

[0049] During the feeding process, after the first gripper 40 and the second gripper 41 move horizontally to tension the fabric, the control unit controls the third gripper 42 to grip the fabric between the first gripper 40 and the second gripper 41. Subsequently, the control unit controls the mounting frame 20 to move up and down rapidly on the support frame 80 to shake the fabric a set number of times. In this way, the fabric that has been gripped multiple times can be shaken off, thereby increasing the probability of gripping a single layer of fabric at a time.

[0050] After the shaking is completed, the mounting frame 20 moves to the set feeding position and the gripper releases the fabric. The first gripper 40, the second gripper 41 and the third gripper 42 grip the fabric at different positions, which can reduce the probability of the fabric falling off during the feeding process.

[0051] In some embodiments of this utility model, the gripping component is a needle-type suction cup. The needle-type suction cup has a high probability of successfully gripping the fabric and low energy consumption, thereby improving the reliability of the feeding device 100 during operation and reducing the energy consumption of the feeding device 100.

[0052] According to the production system 1000 of the second aspect embodiment of the present utility model, such as Figure 1 As shown, it includes: the feeding device 100, the conveying device 200, and the conveying device 300 according to the first aspect embodiment of the present utility model.

[0053] Specifically, the feeding device 200 includes a feeding bracket 210 and a feeding platform 220. The feeding platform 220 is movably mounted on the feeding bracket 210. The feeding platform 220 is used to stack fabric, and the conveying device 300 is used to convey the fabric.

[0054] The feeding bracket 210 is equipped with a feeding motor 230. The feeding bracket 210 and the feeding platform 220 are connected by a ball screw structure. The feeding motor 230 drives the feeding platform 220 to move up and down through the ball screw structure. The conveying device 300 includes a conveyor belt 320 and a conveying motor 310. The conveying motor 310 drives the conveyor belt 320 to move.

[0055] During the feeding process, the gripper control support frame 80 moves in the second direction to adjust the relative position of the mounting frame 20 and the feeding platform 220 in the second direction, and moves the mounting frame 20 above the feeding platform 220. Then, the control unit controls the mounting frame 20 to move downward on the support frame 80, and the feeding platform 220 drives the fabric to move upward until the fabric contacts the gripper. Then, the control unit controls the gripper to grab the fabric. Subsequently, the control unit controls the mounting frame 20 to move above the conveyor belt 320 and place the fabric on the conveyor belt 320. The conveyor belt 320 transports the fabric to the downstream process, thus realizing the automatic feeding process.

[0056] According to the production system 1000 of the second aspect of the present invention, by setting the feeding device 100 according to the first aspect of the present invention, automatic feeding of fabric can be realized, thereby improving production efficiency.
