Description

Technical Field

[0001] This invention relates to the field of garment processing equipment technology, and more specifically to an automatic pad-adding device for a button-attaching machine. Background Technology

[0002] A button-attaching machine is a specialized automatic sewing machine used for sewing buttons with regular shapes and for "stitching" or "drip" sewing processes, such as attaching labels, tags, and caps. The most common type used is the sewing of round, two- or four-hole (also known as flat buttons) buttons. By replacing various specialized button-attaching machine accessories, one machine can sew various types of buttons, including handle buttons, metal buttons, snap buttons, loop buttons, and top buttons. Users can request specialized accessories from the equipment supplier as needed.

[0003] Traditional button-attaching machines require multiple people to work together when attaching buttons to fabric. The pads need to be placed manually, resulting in significant manpower waste, low efficiency, high costs, and increased worker safety. While there are devices that automatically add button pads, they typically rely on gravity to allow the pads to fall onto the buttons from above. This method of pad dropping is prone to issues in practice, such as missed pads or multiple pads falling onto a single button. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic shim-adding device for a button-attaching machine. This device automatically adds shims to the buttons, adding one shim to each button each time, preventing any omissions or over-additions. This reduces manual labor intensity and improves work efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic pad-adding device for a button-attaching machine, comprising a feeding tray and a base, characterized in that: a pad guide rail and a button-attaching guide rail are inclinedly arranged on the feeding tray; a pad-adding mechanism is provided on the base; the pad-adding mechanism includes a feeding plate, a baffle assembly, and a suction cup mechanism; a material-retrieving station is provided below the suction cup mechanism; the feeding plate is located at the outlet position of the pad guide rail and is slidably connected to the base, which can transport the pad from the outlet position to the material-retrieving station; a cleaning baffle is provided on the sliding path of the feeding plate, which can return the excessively stacked pads to the feeding tray;

[0006] The baffle assembly is disposed on one side of the fastener guide rail. The baffle assembly includes a separating baffle, a feeding baffle, and a limiting baffle arranged sequentially at the feeding point of the fastener guide rail. The baffle assembly is slidably connected to the base, so that the separating baffle, the feeding baffle, and the limiting baffle extend and retract synchronously in the direction perpendicular to the path of the fastener guide rail. An installation station is formed between the limiting baffle and the feeding baffle, and a preparation station is formed between the separating baffle and the feeding baffle.

[0007] When the baffle assembly retracts synchronously, the small baffle at the end of the feed baffle temporarily blocks the rivet to be processed, keeping it in the preparation position. When the baffle assembly extends synchronously, the feed baffle releases the blocked rivet and enters the installation position. The limiting baffle blocks the rivet and keeps it in the installation position. The separating baffle separates the subsequent rivets to be processed.

[0008] The suction cup mechanism is equipped with a suction cup for picking up the pad, and the suction cup moves between the material picking station and the installation station.

[0009] The present invention is further configured such that: the suction cup mechanism includes a support frame, a transverse slide rail, a longitudinal slide rail, and a suction cup; the support frame is disposed on a base; the suction cup is disposed on the longitudinal slide rail; the suction cup can slide up and down between the pad-picking position and the pad-installing position to achieve the picking up and installation of the pad; the longitudinal slide rail is disposed on the transverse slide rail; the suction cup can move laterally between the pad-picking position and the pad-installing position under the action of the transverse slide rail to achieve the lateral transport of the pad.

[0010] The invention is further configured such that: the separating baffle is perpendicular to the surface of the fastener guide rail; one end of the feeding baffle is parallel to the surface of the fastener guide rail, and the height difference allows the fastener to pass through; the other end is bent downwards and contacts the surface of the fastener guide rail, and the bent part forms a small baffle to block the fastener; the distance between the separating baffle and the feeding baffle allows one fastener to enter; the limiting baffle is flat and closely attached to the surface of the fastener guide rail; the separating baffle and the limiting baffle are of the same length; and the length of the feeding baffle is greater than that of the separating baffle and the limiting baffle.

[0011] The invention is further configured such that: a fixing post is provided on the feeding plate, the fixing post is used to fix the position of the gasket, and the feeding plate is located above the feeding tray, so that the gasket falling from the feeding plate can return to the feeding tray.

[0012] The present invention is further configured such that: the feeding plate is a vibrating feeding plate, the feeding plate is provided with a feeding track that is circumferentially upward along the outer edge of the feeding plate, the upper part of the feeding track is provided with a screening plate, the screening plate is circumferentially arranged, and a gap is provided between the bottom of the screening plate and the surface of the feeding plate for a gasket to pass through.

[0013] The present invention is further configured such that: the screening plate divides the two sides of the feeding track into two areas, the inner side of the screening plate is the buckle feeding area, and the outer side is the gasket feeding area, the gasket feeding area is connected to the gasket guide rail, and the buckle feeding area is connected to the buckle guide rail.

[0014] The present invention is further configured such that: a blocking plate is provided at the connection between the fastener feeding area and the fastener guide rail, and a gap matching the thickness of the fastener is provided between the blocking plate and the surface of the fastener feeding area.

[0015] The present invention is further configured to include a driving mechanism, which includes a first cylinder, a second cylinder, a third cylinder, a fourth cylinder, and a fifth cylinder, and is connected to an external air source. The first cylinder drives the feeding plate, the second cylinder drives the baffle assembly, the third cylinder and the fourth cylinder are respectively used to drive the suction cup to move on the longitudinal slide rail and the transverse slide rail, and the fifth cylinder is used to control the suction cup to suck air.

[0016] In summary, the present invention has the following beneficial effects:

[0017] Compared to existing technologies, this invention incorporates a gasket loading mechanism and a suction cup mechanism. The gasket falls from the gasket guide rail onto the feeding plate. A first cylinder drives the feeding plate to extend and retract, transporting the gasket to the gasket loading port. Then, a third and fifth cylinder control the suction cup mechanism to move downwards and pick up the gasket, moving it upwards to remove it from the feeding plate. A fourth cylinder controls the suction cup to move laterally, moving it above the gasket loading port. Below the loading port is a baffle assembly, which guides the continuously fed fasteners from the fastener guide rail through the baffle assembly, ensuring that only one fastener is positioned below the loading port at a time. The suction cup then moves downwards and releases the gasket, attaching it to the fastener. This process is repeated, continuously attaching gaskets to fasteners, while the feeding plate... The device is equipped with fixed posts, on which the gaskets fall and stack. Gaskets that do not fall onto the fixed posts will fall back into the feeding tray for re-screening and feeding. Gaskets that are stacked too high will be blocked by the cleaning baffle during the sliding of the feeding plate and will also fall into the feeding tray. When the gaskets on the fixed posts are picked up by the suction cup, it is ensured that they are not picked up crookedly, which makes it easy to install the gaskets correctly onto the fasteners later. At the same time, the suction cup picks up only one gasket at a time, and the baffle assembly can control the fasteners to enter the space below the gasket installation opening in sequence. This solves the problem of gaskets not falling onto the fasteners or multiple gaskets falling onto one fastener in the actual use of the existing technology that uses gaskets falling, which is prone to problems in actual use.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] This embodiment discloses an automatic gasket-adding device for a button-attaching machine, referring to... Figure 1 Both the fasteners and the gaskets are placed in the feeding tray 1. The feeding tray 1 uses vibration to transport the fasteners and gaskets to the feeding guide rail 14. After being screened by the screening plate 1401 and the gap 1402, the gaskets enter the gasket feeding area 16 from the gap 1402 and continue to the gasket guide rail 4. The fasteners move along the fastener feeding area 15 and are screened by the thickness of the blocking plate 17. Some fasteners and gaskets that are stacked together in the feeding tray 1 due to vibration are blocked back into the feeding tray 1 because they are thicker. Since it is impossible to determine whether there is only one gasket among the fasteners and gaskets that are stacked together, they are blocked from entering the subsequent process and are separated again under the vibration of the feeding tray 1. The remaining fasteners will enter the fastener guide rail 5.

[0026] Reference Figure 1 and Figure 2The pads that fall from the outlet of the pad guide rail 4 will land on the feeding plate 6. The pads that fall on the fixing post 601 will be retained, and the remaining pads will fall back into the feeding tray 1. Then, the feeding plate 6 moves to the picking station 201 under the drive of the first cylinder 9. During this process, the pads that are stacked too high will be blocked back into the feeding tray 1 by the cleaning baffle 19. The pads remaining on the fixing post 601 will reach the picking station 201 and be picked up by the suction cup 804. The top pad is then picked up by the suction cup mechanism 8 and moved to the installation station 202 to install the pad onto the fastener. Since the suction cup 804 picks up only one pad at a time, and the fixing post 601 determines the position of the pad, there will be no problem of multiple pads being installed on the fastener or the pads being picked up crookedly and unable to be installed.

[0027] Reference Figure 4 and Figure 5 When the fastener moves on the fastener guide rail 5, the baffle assembly 7 extends under the control of the second cylinder 10, and the fastener is blocked by the separating baffle 701. When the baffle assembly 7 retracts, the separating baffle 701 is released, and the fastener advances a distance and is blocked again by the small baffle 7021 at the front end of the feeding baffle 702. The space between the separating baffle 701 and the feeding baffle 702 is set as the preparation station 20, and the distance is exactly the width of one fastener. When the baffle assembly 7 extends again, the separating baffle 701 separates the fastener in the preparation station 20 from the fastener to be processed, and blocks the fastener to be processed. The fastener in the preparation station 20 is no longer blocked due to the movement of the feeding baffle 702. The device continues to move and is stopped by the limiting baffle 703, stopping at the installation station 202. At the same time, the suction cup mechanism 8 will drive the suction cup 804 to install the pad onto the snap fastener in the installation station 202. Then the baffle assembly 7 retracts, and the installed snap fastener and pad continue to move, leaving the snap fastener guide rail 5 and entering the subsequent process. Another snap fastener to be processed will enter the preparation station 20 and be stopped by the feeding baffle 702. After the baffle assembly 7 extends, the snap fastener in the preparation station 20 enters the installation station 202 to install the pad. This process is repeated. Each time the baffle assembly 7 extends and retracts, it delivers a snap fastener to the installation station 202 for installation, ensuring that no snap fastener is missed.

[0028] Reference Figure 3 The entire suction cup mechanism 8 is mounted on the base 2 via a support frame 801. The suction cup 804 is mounted on the longitudinal guide rail 803, which is in turn mounted on the transverse guide rail 802. It is moved by the third cylinder 11 and the fourth cylinder 12. A fifth cylinder 13 provides suction force to the suction cup 804. In this way, the suction cup 804 can pick up the pad at the material picking station 801 and move on the longitudinal guide rail 803 and the transverse guide rail 801 to transport the pad to the installation station 202. Then, the pad is released and installed on the fastener.

Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present invention should be included within the protection scope of the present invention.
