Description

Technical Field

[0001] The utility model relates to the technical field of template machines, and more specifically, to a device for picking and placing a bobbin case. In addition, the utility model also relates to a template machine including the above device for picking and placing a bobbin case. Background Art

[0002] In the technical field of template machines, a lockstitch requires a rotary hook and a sewing needle to cooperate with each other to interweave and lock the bobbin thread and the face thread on the fabric to form a stitch. Among them, the face thread is connected to a thread spool, the bobbin thread is connected to a bobbin inside the rotary hook, and the amount of the bobbin thread on the bobbin is limited, so the bobbin needs to be frequently replaced.

[0003] In the related art, a bobbin is replaced by an automatic bobbin-changing device. Specifically, when a bobbin-changing signal is received, the automatic bobbin-changing device takes out the bobbin case and the bobbin inside the rotary hook, and then grabs the bobbin and the bobbin case wound with the full bobbin thread in a spare bobbin tray and puts them into the rotary hook to complete the replacement of the bobbin. After the replacement, the spring pressure is used to reset the bobbin-changing device to wait for the next operation. However, the bobbin-changing device needs to grab the bobbin case from the rotary hook and put the bobbin case into the rotary hook multiple times. Since the elastic member is a non-rigid body, relying only on the spring to reset easily causes the initial position of the bobbin-changing device to change. For example, when resetting, the bobbin-changing device rotates or deviates, etc., affecting the success rate of placing the bobbin case.

[0004] In summary, how to avoid the change of the initial position of the bobbin-changing device is an urgent problem to be solved by those skilled in the art at present. Summary of the Utility Model

Detailed implementation manners

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the protection scope of the present utility model.

[0045] The core of the present utility model is to provide a shuttle shell picking and placing device, which can ensure the accuracy of the floating seat to reset to the initial state after floating and improve the success rate of picking up the shuttle shell. Another core of the present utility model is to provide a template machine including the above-mentioned shuttle shell picking and placing device.

[0046] The shuttle shell picking and placing device provided by the present utility model includes a shuttle picking mechanism 6. The shuttle picking mechanism 6 is used to take out the shuttle shell and the bobbin in the rotating shuttle, and then pick up the bobbin and the shuttle shell wound with the bottom thread in the spare bobbin tray and put them into the rotating shuttle to complete the replacement of the bobbin. Specifically, when the shuttle picking mechanism 6 picks up the shuttle shell, it can have a certain floating space. Even when there is misalignment and offset between the shuttle picking mechanism 6 and the shuttle shell, the shuttle shell can still be successfully picked up, ensuring the success rate of picking up the shuttle shell.

[0047] The floating seat 1 is connected to the shuttle picking mechanism 6, and the floating of the shuttle picking mechanism 6 is realized through the floating of the floating seat 1. Specifically, an elastic member 5 is provided between the base 2 and the floating seat 1. The compressed state of the elastic member 5 corresponds to the shuttle picking state, and the shuttle picking mechanism 6 moves to pick up the shuttle shell; the reset state of the elastic member 5 corresponds to the shuttle releasing state, and the floating seat 1 drives the shuttle picking mechanism 6 to reset. Please refer to Figure 1 、 Figure 2 。

[0048] The positioning guide post 3 is fixed on the base 2 and passes through the floating seat 1. The anti-rotation guide post 4 is arranged in parallel with the positioning guide post 3 and is fixed on the base 2. Please refer to Figure 1 , the lower parts of the positioning guide post 3 and the anti-rotation guide post 4 are both fixed on the base 2, and the upper parts are connected to the floating seat 1. In the compressed state of the elastic member 5, the floating seat 1 can have a certain floating space relative to the upper parts of the positioning guide post 3 and the anti-rotation guide post 4, realizing the appropriate floating of the shuttle picking mechanism 6 for pose adjustment. When there is offset or misalignment between the position of the shuttle shell and the shuttle picking mechanism 6, the success rate of shuttle picking is ensured through the floating of the shuttle picking mechanism 6.

[0049] Among them, the positioning guide post 3 is the main component providing the floating space for the floating seat 1, and the anti-rotation guide post 4 is used to limit the rotation of the floating seat 1. The so-called limiting rotation here means that in the reset state of the elastic member 5, with the cooperation of the elastic member 5, the rotation of the floating seat 1 around the positioning guide post 3 is restricted, so that the floating seat 1 can quickly return to the initial position accurately with the help of the elastic force under the action of the two guide posts, avoiding affecting the next operation of transferring the shuttle shell or picking and placing the shuttle shell.

[0050] In the shuttle grasping state, the elastic member 5 is compressed and deformed, creating a floating space between the positioning guide post 3 and the anti-rotation guide post 4 and the floating seat 1. When the shuttle grasping mechanism 6 grasps the shuttle shell, the movement of the floating seat 1 within the floating space can ensure the reliable grasping of the shuttle shell by the shuttle grasping mechanism 6. The movement direction here can refer to multiple directions, such as front-back, up-down, left-right directions, etc. Under the action of the anti-rotation guide post 4, the entire floating seat 1 will not rotate around the positioning guide post 3, avoiding the situation of being unable to reset to the initial state and ensuring accurate reset.

[0051] In the shuttle releasing state, the elastic member 5 resets, locking the floating seat 1 to the positioning guide post 3 and the anti-rotation guide post 4 to complete the reset.

[0052] The above-mentioned shuttle shell picking and placing device, through the cooperative setting of the anti-rotation guide post 4 and the positioning guide post 3, can make the floating seat 1 have a floating space when the elastic member 5 is compressed, so as to realize the pose adjustment of the shuttle grasping mechanism 6 when grasping the shuttle shell; when the elastic member 5 resets, the floating seat 1 can be locked to the anti-rotation guide post 4 and the positioning guide post 3 to limit the rotation of the floating seat 1, enabling the floating seat 1 to reset to the initial state, ensuring the accuracy of the floating seat 1 to reset to the initial state after floating, and improving the success rate of grasping the shuttle shell.

[0053] Based on the above embodiment, the floating seat 1 includes a first adjustment portion 11 and a second adjustment portion 12 connected thereto. The positioning guide post 3 passes through the first adjustment portion 11 and the second adjustment portion 12, and the anti-rotation guide post 4 passes through the second adjustment portion 12;

[0054] One end of the elastic member 5 is fixed within the base 2, and the other end of the elastic member 5 is fixed within the second adjustment portion 12.

[0055] Please refer to Figure 1 , the floating seat 1 includes a first adjustment portion 11 and a second adjustment portion 12 connected thereto. Among them, the positioning guide post 3 passes through the first adjustment portion 11 and the second adjustment portion 12 and is then fixed to the base 2, and the anti-rotation guide post 4 passes through the second adjustment portion 12 and is fixed to the base 2.

[0056] When grasping the shuttle shell, the elastic member 5 fixed between the base 2 and the second adjustment portion 12 is compressed and will move. There are gaps between the floating seat 1 and the positioning guide post 3, and between the floating seat 1 and the anti-rotation guide post 4 to perform the floating adjustment of the floating seat 1.

[0057] When putting down the shuttle shell, the elastic member 5 resets. Under the action of the reset force, the floating seat 1 resets to the original state and is locked on the positioning guide post 3 and the anti-rotation guide post 4.

[0058] Based on any of the above embodiments, the anti-rotation guide post 4 includes:

[0059] The first main body 42;

[0060] The first abutting portion 41, which is arranged on the first main body 42 and abuts against the top surface of the second adjusting portion 12;

[0061] The second abutting portion 43, which is arranged on the lower side of the first abutting portion 41. The second abutting portion 43 abuts against the top surface of the floating seat 1 and cooperates with the first abutting portion 41 to limit the rotation of the floating seat 1.

[0062] Please refer to Figure 3 and Figure 7 , the anti-rotation guide post 4 includes the first main body 42, the first abutting portion 41 and the second abutting portion 43.

[0063] Both the first abutting portion 41 and the second abutting portion 43 are arranged on the first main body 42, and the cross sections of the two abutting portions can be irregular shapes such as circular, square, square with a circular inner part, etc.

[0064] When the cross section of the abutting portion is circular, the diameters of the two abutting portions are both larger than the diameter of the first main body 42 to ensure a reliable abutting effect. Specifically, in the shuttle-taking state, the first abutting portion 41 is away from the top surface of the second adjusting portion 12, and the second abutting portion 43 is away from the top surface of the floating seat 1, without restricting the floating of the floating seat 1. Utilizing the floating space between the first main body 42 and the floating seat 1, the floating seat 1 can perform floating adjustment.

[0065] In the shuttle-releasing state, under the action of the restoring force of the elastic member 5, the first abutting portion 41 abuts against the top surface of the second adjusting portion 12, and the second abutting portion 43 abuts against the top surface of the floating seat 1, restricting the floating of the floating seat 1 and enabling the floating seat 1 to quickly and accurately return to the original state.

[0066] On the basis of any of the above embodiments, the positioning guide post 3 includes:

[0067] The second main body 32;

[0069] The fourth abutting portion 34, which is correspondingly arranged with the second abutting portion 43 and abuts against the top surface of the floating seat 1.

[0070] Please refer to Figure 1 and Figure 6 , the positioning guide post 3 includes the second main body 32, the third abutting portion 33 and the fourth abutting portion 34.

[0071] Both the third abutting portion 33 and the fourth abutting portion 34 are arranged on the second main body 32 and their diameters are both larger than the diameter of the second main body 32 to ensure a reliable abutting effect.

[0072] In the shuttle-taking state, under the action of the elastic member 5, the third abutting portion 33 and the first abutting portion 41 are both away from the top surface of the second adjusting portion 12, and the fourth abutting portion 34 and the second abutting portion 43 are both away from the top surface of the base 2. There are gaps between the first main body 42 and the floating seat 1, and between the second main body 32 and the floating seat 1, so as to facilitate the floating adjustment of the floating seat 1, realize the pose adjustment of the shuttle-grabbing mechanism 6, and ensure the success rate of shuttle-grabbing.

[0073] In the shuttle-releasing state, under the action of the restoring force of the elastic member 5, the third abutting portion 33 and the first abutting portion 41 both abut against the top surface of the second adjusting portion 12, and the fourth abutting portion 34 and the second abutting portion 43 both abut against the top surface of the base 2, so as to limit the floating of the floating seat 1 and enable the floating seat 1 to be reset to the initial position.

The inner wall of the floating chamber 111 can be a waist-shaped hole, a square hole with arc-shaped sides, a long strip hole, etc. The floating chamber 111 can move relative to the floating portion 31 to realize the floating adjustment of the floating seat 1 in multiple directions.

[0076] In the shuttle-releasing state, the floating portion 31 fits inside the floating chamber 111; in the shuttle-taking state, the floating portion 31 is away from the floating chamber 111, and a floating space is generated between the floating chamber 111 and the second main body 32 for the floating adjustment of the floating seat 1.

[0077] Based on any of the above embodiments, the floating portion 31 includes a flat portion and a guiding portion extending into the first adjusting portion 11. The flat portion abuts against the top of the floating chamber 111, and the size of the guiding portion gradually decreases along the direction close to the bottom of the floating chamber 111.

[0078] Please refer to Figure 3 、 Figure 4 、 Figure 6 , the floating portion 31 includes a flat portion and a guiding portion. In the shuttle-releasing state, the flat portion abuts against the top of the floating chamber 111 to limit the floating of the floating seat 1, and the guiding portion fits against the inner wall of the floating chamber 111 for positioning; in the shuttle-taking state, both the flat portion and the guiding portion are away from the floating chamber 111, and a floating space is generated between the floating chamber 111 and the second main body 32 for the floating adjustment of the shuttle-grabbing mechanism 6 to ensure the reliable grabbing of the shuttle shell.

[0079] The guiding portion is dimensionally reduced along the direction approaching the bottom of the floating chamber 111 to form a guiding conical surface.
