Description

Technical Field

[0001] This utility model relates to the field of garment processing equipment, and in particular to an anti-hand-slapping device for an automatic button-attaching machine and an automatic button-attaching machine. Background Technology

[0002] In the garment production process, since clothes and shoes need to be fitted with multiple buttons, button attaching machines are usually used for automated button attaching. In order to install the buttons in the designated positions, it is generally necessary to manually place and fix the products to be attached to the buttoning table for auxiliary button attaching. This poses certain safety risks. If the manual placement is not well coordinated with the button attaching machine, there is a high risk of the button attaching machine hitting the operator's hand.

[0003] In existing technologies, the safety of operators relies almost entirely on their own attention. However, if operators are not focused enough during prolonged operation, accidents may occur, resulting in finger injuries.

[0004] It is evident that existing technologies pose a safety hazard, potentially leading to injuries to operators' hands. Utility Model Content

[0005] This utility model provides an anti-hand-slapping device for an automatic button-attaching machine and an automatic button-attaching machine, which solves the safety hazard problem of operators being easily injured by hand in the prior art.

[0006] This utility model provides an anti-hand-slapping device for an automatic button-attaching machine, including a baffle, a mounting bracket, and a trigger;

[0007] The baffle is located on the upper side of the fastening area in the fastening station, and the baffle is spaced apart from the fastening station. The baffle includes a first plate segment and a second plate segment. The first end of the second plate segment is connected to the first end of the first plate segment. The trigger element is located at the second end of the second plate segment and is used to trigger an alarm signal.

[0008] The first end of the first plate segment is rotatably connected to the mounting bracket. The second end of the first plate segment can move closer to or further away from the fastening table between the first position and the second position under the action of external force. The second end of the second plate segment can follow the first plate segment between the initial position and the trigger position.

[0009] When the second end of the first plate segment moves away from the fastening table to the second position, the second end of the second plate segment is in the trigger position, so that the triggering element triggers the alarm signal.

[0010] This invention triggers an alarm signal via a baffle located above the fastening area of ​​the fastening platform. When a person's hand remains in the fastening area, the hand drives the second end of the first plate segment away from the fastening platform to a second position (or, as can be understood, the hand drives the first plate segment to rotate clockwise around its first end). At this time, the second plate segment follows the movement of the first plate segment and reaches the trigger position, triggering the alarm signal. Therefore, this invention achieves physical recognition of the person's hand through the cooperation of the baffle and the trigger, effectively avoiding the safety hazard of operator hand injury.

[0011] Furthermore, since this invention uses direct contact recognition between the baffle and the user's hand, rather than signal recognition, it greatly avoids the misjudgments that often occur with signal recognition. Therefore, it prevents frequent alarms or shutdowns during production, significantly improving button-attaching efficiency. In addition, this invention also has the advantages of simple structure and convenient installation.

[0012] Optionally, the automatic button-attaching machine's anti-hand-slapping device also includes a drive unit connected to the mounting bracket to drive the mounting bracket to move between a target position and a non-target position;

[0013] The target position is configured such that the relative distance between the first plate segment installed on the mounting bracket and the fastening area in the first position is a preset distance.

[0014] This utility model embodiment utilizes a drive unit that allows for arbitrary adjustment of the distance between the baffle and the snap-on area, thereby enabling different safety distances to be adapted for different products to be snapped on, making this utility model embodiment applicable to a wider range of application scenarios.

[0015] Optionally, the automatic button-attaching machine's anti-hand-striking device also includes a trigger mounting plate, which is fixed to the side of the mounting bracket away from the first plate segment, and the trigger is mounted on the trigger mounting plate.

[0016] Optionally, the automatic button-attaching machine's anti-hand-slapping device also includes an elastic element, with its two ends connected to the second end of the second plate segment and the trigger mounting plate, respectively. The elastic element is used to reset the second plate segment from the trigger position to the initial position.

[0017] Optionally, the elastic element can be a tension spring or a spring.

[0018] Optionally, the trigger is an alarm switch.

[0019] Optionally, the trigger is a distance sensor.

[0020] Optionally, the second end of the first plate segment in the baffle is a ring structure.

[0021] In this embodiment of the invention, the second end of the first plate segment adopts a ring structure, which can greatly reduce the interference of the baffle on other components of the fastener machine and provide more possibilities for the installation and movement of other components.

[0022] Optionally, the annular structure has at least one notch.

[0023] In this embodiment of the invention, the annular structure has at least one notch, which allows laser or infrared light to pass through for precise positioning of the fastener.

[0024] This utility model also provides an automatic button-attaching machine, which employs the anti-hand-slapping device of the automatic button-attaching machine involved in the above embodiments and possible implementation methods. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0040] This invention relates to an automatic button-attaching machine, which is used to automatically attach buttons to clothing, including clothes, shoes, bags, etc.

[0041] Please see Figure 1 and Figure 2 This utility model provides an anti-hand-slapping device 1 for an automatic button-attaching machine, including a baffle 10, a mounting bracket 13, and a trigger 14. The baffle 10 is located on the upper side of the button-attaching area 2 in the button-attaching platform, and the baffle is spaced apart from the button-attaching platform. The baffle 10 includes a first plate segment 11 and a second plate segment 12, with the first end 121 of the second plate segment 12 connected to the first end 111 of the first plate segment 11. The trigger 14 is located at the second end 122 of the second plate segment 12 and is used to trigger an alarm signal.

[0042] The first end 111 of the first plate segment 11 is rotatably connected to the mounting bracket 13. The second end 112 of the first plate segment 11 can move closer to or further away from the fastening table between the first position and the second position under the action of external force. The second end 122 of the second plate segment 12 can follow the first plate segment 11 between the initial position and the trigger position.

[0043] When the second end 112 of the first plate segment 11 moves away from the fastening table to the second position (e.g.) Figure 2When (as shown), the second end 122 of the second plate segment 12 is in the trigger position, so that the trigger 14 triggers the alarm signal.

[0044] like Figure 1 As shown, the trigger position is understood to be the trigger end 140 of the trigger element 14 abutting against the second plate segment 12.

[0045] In one embodiment, the first plate segment 11 and the second plate segment 12 can be an integral plate-shaped rigid structure. In other alternative embodiments, the first plate segment 11 and the second plate segment 12 can also be two separate structures. As long as the second plate segment 12 can be located at the trigger position when the first plate segment 11 moves to the second position, it does not deviate from the scope of the present utility model embodiment.

[0046] This utility model triggers an alarm signal via a baffle 10 located above the fastening area 2 of the fastening table. Specifically, when a person's hand has not been removed from the fastening area (e.g., Figure 2 As shown, a person's hand drives the second end 112 of the first plate segment 11 away from the fastening table to the second position (or it can be understood as the person's hand driving the first plate segment 11 to rotate clockwise around its first end 111). At this time, the second plate segment 12 follows the first plate segment 11 and reaches the trigger position, triggering the alarm signal. It can be seen that this utility model realizes the physical recognition of the person's hand through the cooperation of the baffle 10 and the trigger 14, effectively avoiding the safety hazard of the operator being injured by hitting their hand.

[0047] Furthermore, since this invention uses direct contact recognition between the baffle and the user's hand, rather than signal recognition, it greatly avoids the misjudgments that often occur with signal recognition methods such as laser or infrared lights. Therefore, it avoids frequent alarms or shutdowns during production, significantly improving button-attaching efficiency. In addition, this invention also has the advantages of simple structure and convenient installation.

[0048] In one embodiment, the first end 111 of the first plate segment 11 is rotatably connected to the mounting bracket 13 via a rotating shaft 113. In one example, the rotating shaft 113 is located at the first end 111 of the first plate segment 11, and the mounting bracket 13 has a mounting hole through which the rotating shaft 113 passes. In other examples, the rotating shaft 113 may also be located on the mounting bracket 13, and the first end 111 of the first plate segment 11 has a mounting hole through which the rotating shaft 113 passes.

[0049] In one embodiment, the trigger 14 is an alarm switch. When the second end 122 of the second plate segment 12 is in the initial position, the alarm switch is in contact with the second end 122 of the second plate segment 12 and closed. At this time, the circuit is closed and no alarm signal is triggered. When the second end 122 of the second plate segment 12 is in the trigger position, the second end 122 of the second plate segment 12 leaves the alarm switch. At this time, the circuit is open and an alarm signal is triggered.

[0050] In other alternative embodiments, the trigger 14 is a distance sensor. The distance sensor detects the real-time distance between itself and the second end 122 of the second plate segment 12. When the second end 122 of the second plate segment 12 is in the initial position, the distance sensor detects that the real-time distance is less than or equal to a threshold distance, and no alarm signal is triggered. When the second end 122 of the second plate segment 12 is in the trigger position, the distance sensor detects that the real-time distance is greater than the threshold distance, and an alarm signal is triggered. The threshold distance can be set as needed according to actual conditions. In one example, the distance sensor is in contact with the second plate segment 12 in the initial position, so the threshold distance is zero.

[0051] In one embodiment, the automatic button-attaching machine anti-hand-slapping device 1 further includes a trigger mounting plate 141, which is fixed to the side of the mounting bracket 13 away from the first plate segment 11, and the trigger 14 is mounted on the trigger mounting plate 141. Those skilled in the art will understand that the trigger mounting plate 141 may be integrally formed with the mounting bracket 13, or it can be understood that the trigger mounting plate 141 is part of the mounting bracket 13, or the trigger mounting plate 141 may be a separate structure mounted on the mounting bracket 13.

[0052] Furthermore, the automatic button-attaching machine's anti-hand-slapping device 1 also includes an elastic element 16. The two ends of the elastic element 16 are respectively connected to the second end 122 of the second plate segment 12 and the bottom of the trigger mounting plate 141. The elastic element 16 is used to reset the second plate segment 12 from its self-triggered position to its initial position. The elastic element 16 can be, for example, a tension spring, a spring, etc. It utilizes its own deformation and recovery ability to reset the second plate segment 12 from its self-triggered position (e.g., Figure 2 Reset to the initial position (as shown) Figure 1 (As shown).

[0053] This invention does not limit the shape of the baffle 10; it can be a plate-like structure, a strip-like structure, a column-like structure, etc. In one embodiment, such as... Figure 1 and Figure 2 As shown, the second end 112 of the first plate segment 11 in the baffle 10 has a ring-shaped structure, such as a circular ring, a rectangular ring, a triangular ring, etc. This structure greatly reduces the interference of the baffle 10 with other components of the fastener machine, providing more possibilities for the installation and movement of other components.

[0054] In a further embodiment, the annular structure has at least one notch 114, which allows laser or infrared light to pass through for precise positioning of the button. For example, an automatic button-attaching machine is equipped with a laser positioner that emits a laser to the button position on the product to be buttoned. In this embodiment, one or more notches 114 can be made in the annular structure for the laser to pass through. Those skilled in the art will understand that the notch 114 can be achieved by cutting off a portion of the annular structure or by making a portion of the annular structure transparent, as long as the notch 114 allows the laser to pass through, it does not depart from the scope of this embodiment.

[0055] Because this utility model is applicable to button-sewing operations on various products, such as clothing, footwear, and bags, and because different products have different heights, the height of the baffle 10 during button sewing also varies. Furthermore, as... Figure 1 and Figure 2 As shown, the automatic button-attaching machine anti-hand-slapping device 1 also includes a drive unit 15, which is connected to the mounting bracket 13 to drive the mounting bracket 13 to move between a target position and a non-target position. The target position is configured such that the relative distance between the first plate segment 11 installed on the mounting bracket 13 and the button-attaching area 2 in the first position is a preset distance.

[0056] like Figure 2 As shown, if the product 3 to be fastened is footwear, its height is significantly higher than that of clothing. Therefore, the preset distance for footwear needs to be set larger, and the height at which the drive unit 15 drives the mounting bracket 13 to move to the target position needs to be higher.

[0057] In one embodiment, the drive unit 15 includes a telescopic rod 151 and a drive motor 152. The drive motor 152 is connected to one end of the telescopic rod 151 to drive the telescopic rod 151 to extend or retract. The other end of the telescopic rod 151 is connected to the mounting bracket 13. The drive motor 152 controls the movement of the mounting bracket 13 between a target position and a non-target position through the telescopic rod 151. The type of drive motor 152 is not limited; for example, it can be a drive cylinder, a motor, an actuator, etc.

[0058] This utility model embodiment utilizes the drive unit 15 to arbitrarily adjust the distance between the baffle and the snap-on area, thereby adapting different safety distances to different products to be snapped on, making this utility model embodiment applicable to a wider range of application scenarios.

[0059] This utility model also provides an automatic button-attaching machine, which employs the anti-hand-hitting device 1 of the automatic button-attaching machine involved in the above embodiments and possible implementation methods.

[0060] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
