Description

Technical Field

[0001] The present invention relates to the technical field of spring buckle threading devices, and more particularly, to an automated spring buckle threading machine. Background Art

[0002] Spring buckles are accessories widely used in the processing of outdoor clothing such as windbreakers and luggage products. When threading a spring rope through a spring buckle, it is usually necessary to externally press a limiting member to align the limiting hole with the threading hole to facilitate the passage of the spring rope.

[0003] Currently, when performing the threading operation on spring buckles, most are carried out by manually pressing and then threading the spring rope, which not only has low efficiency and high labor intensity, but also requires the spring buckle to be pressed by fingers against each other. Prolonged assembly production can cause discomfort to workers' fingers. Although, currently, to solve the discomfort caused by manual pressing operations, a pressing jig is usually set up to replace manual pressing, but it also requires manual assistance for loading and unloading, and in the short term, the efficiency is even lower than manual operation.

Detailed implementation manners

[0029] Embodiment

[0030] Combined with Figures 1 to 7As shown, this embodiment provides an automated spring buckle threading machine, including a feeding device 6 for transmitting a spring buckle A to a positioning tool 17, a spring rope bracket 2 for storing a spring rope 25, a pressing mechanism 18 for pressing the spring buckle A placed on the positioning tool 17, and also includes a transmission mechanism arranged downstream of the spring rope bracket 2 for transmitting the spring rope 25 along a transmission channel, a spring rope cutting device 10 arranged at an appropriate position of the transmission channel, a turntable 16 connected to the positioning tool 17, an eccentric clamping claw 28 arranged downstream of the positioning tool 17, and a sensor 26 electrically connected to the turntable 16;

[0031] The turntable 16 and the sensor 26 cooperate to rotate the spring buckle A to a position where the rope threading hole is aligned with the transmission channel; the eccentric clamp 28 can move along the transmission direction of the spring rope 25, and can drive one end of the spring rope 25 passing through the first rope threading hole A1 of the spring buckle A to rotate 180 degrees, and then pass through the second rope threading hole A2.

[0032] In this embodiment, specifically, Figures 1 to 3 As shown, the spring rope bracket 2 for storing the spring rope 25 is arranged on the base 1. The transmission mechanism includes a plurality of hollow wire feeding tubes erected on the base 1, and the wire feeding tubes form the transmission channel, through which the spring rope 25 is transmitted; the transmission mechanism also includes a plurality of wire feeding wheel groups, each of which includes two wire feeding rollers 3 that clamp the spring rope 25 and are driven to rotate by the first drive 4, and the first drive 4 is a motor. In this embodiment, two wire feeding wheel groups are included, the first wire feeding wheel group is arranged at the entrance of the first wire feeding tube 5; the second wire feeding wheel group is arranged between the first wire feeding tube 5 and the second wire feeding tube 8. In this embodiment, the wire feeding rollers 3 of the same group are all fixed with mutually meshing gears, one of which is connected to the motor by transmission, and the other group of wire feeding wheel groups is connected by transmission belt.

[0033] In this embodiment, the spring rope cutting device 10 is arranged between the second wire feeding tube 8 and the third wire feeding tube 9. It adopts a heat cutter, and heats the blade through a heating source, so that the blade of the heat cutter can melt the spring rope 25, so that the cut of the spring rope 25 has a cleaner cross section, reduces burrs and damage, and facilitates the spring rope 25 to pass through the spring buckle A.

[0034] In this embodiment, the feeding device 6 is a vibrating bowl. The vibrating bowl is used to convey the spring buckle A, and a spring buckle limiting block 601 is arranged thereon, so that the vibrating bowl can only sequentially output the spring buckle A with the front side facing up, and the spring buckle A with the back side facing up is bounced back into the vibrating bowl by the limiting block 601 and vibrated again into the spring buckle A with the front side facing up before being conveyed. At the discharge port of the discharge channel of the feeding device 6, a sequential feeding mechanism 7 is arranged, which includes a second drive 12, as well as a first baffle 13 and a second baffle 14; each time the second drive 12 drives the first baffle 13 and the second baffle 14 to move back and forth on the discharge channel, the blanking of one spring buckle A is realized. Specifically, as Figure 6 shown, the first baffle 13 and the second baffle 14 are arranged at an interval along the distance of the outer dimension of one spring buckle A, and a notch for the first baffle 13 and the second baffle 14 to pass through is respectively arranged on the left and right sides of the side wall of the discharge channel, so that the first baffle 13 and the second baffle 14 can move back and forth along the direction perpendicular to the discharge direction of the discharge channel under the drive of the second drive 12; and when the first baffle 13 and the second baffle 14 are pulled back and forth once under the drive of the second drive 12, the feeding of one spring buckle A is realized.

[0035] Preferably, it further includes a third drive 15, which can be a cylinder, and is used to drive the positioning tooling 17 to approach or move away from the discharge port, so that the discharge port is flush with the positioning tooling 17, facilitating the spring buckle A to smoothly fall into the positioning tooling 17.

[0036] And as Figure 8 and Figure 9 shown, the front side of the spring buckle A has a first string-passing hole A1 and a second string-passing hole A2 for passing through the spring rope 25; and its side has a through hole A4, and the edge part of the through hole A4 is located outside the range of the string-passing hole. Therefore, in this embodiment, the sensor adopts an opposed photoelectric sensor 26, and is arranged at an appropriate position on the side, so that its light can only pass through the edge part of the through hole A4 and cannot pass through the string-passing hole, thereby cooperating with the turntable 16 to rotate the spring buckle A to the position where the string-passing hole is aligned with the transmission channel; specifically, the turntable 16 drives the spring buckle A to rotate. When the light of the opposed photoelectric sensor 26 passes through the through hole A4, an instruction is immediately issued to stop the turntable 16 from rotating. At this time, the string-passing hole of the spring buckle A is exactly aligned with the transmission channel. And under the transmission of the transmission mechanism, one end of the spring rope 25 can pass through the first string-passing hole A1.

[0037] In this embodiment, a pressing mechanism 18 is arranged above the positioning tooling 17. The pressing mechanism 18 includes a pressing block 24 that can move vertically under the drive of a cylinder. After the spring buckle A is loaded onto the positioning tooling 17 and its position is adjusted, the pressing block 24 moves downward to press the spring button of the spring buckle A.

[0038] In this embodiment, a track 27 is arranged on the base 1. The eccentric jaw 28 can move along the track 27 under the drive of a fourth drive to approach or move away from the positioning tooling 17. The eccentric jaw 28 includes a first jaw 19 fixedly arranged on a turntable, and a second jaw 20 that can approach or move away from the first jaw 19 under the drive of a fifth drive; the turntable can rotate under the drive of a sixth drive; the operation process of the eccentric jaw 28 is as follows: when one end of the spring rope 25 passes through the first rope-passing hole A1 and extends a certain length beyond the jaws, the second jaw 20 approaches the first jaw 19 under the drive of the fifth drive, so as to clamp the spring rope 25. Then, under the drive of the fourth drive, the eccentric jaw 28 clamps the spring rope 25 and moves backward a certain distance on the slide rail. Then, under the drive of the sixth drive, one end of the spring rope 25 is rotated 180°. Subsequently, under the drive of the fourth drive, it moves towards the second rope-passing hole A2, and further passes one end of the spring rope 25 through the second rope-passing hole A2 to complete the buckling. In this embodiment, the length that one end of the spring rope 25 passes through the first rope-passing hole A1 and extends beyond the jaws is set to 4 - 5 cm. Under the relatively strong toughness of the spring rope 25, the spring rope 25 hardly sags; and under the drive of the fourth drive, the distance that the eccentric jaw 28 clamps the spring rope 25 and moves backward on the slide rail is set to 6 - 7 cm, which is convenient for subsequently rotating one end of the spring rope 25 by 180°. Of course, in other embodiments, the setting of the above lengths and the backward movement distance can be determined according to the technical requirements of buckling, for example, set according to different materials and the thickness of the spring rope 25.

[0039] Preferably, the first jaw 19 and the second jaw 20 are semi-cylindrical with a certain length, which can effectively avoid the situation that the buckling end is bent under the influence of the rear end after rotating one end of the spring rope 25 by 180°.

[0040] Preferably, an arc-shaped baffle 21 is further arranged on the turntable, which can prevent the spring rope 25 from being damaged due to excessive bending when rotating 180° along with the eccentric jaw 28.

[0041] In this embodiment, a horn-shaped channel is further provided between the eccentric jaw 28 and the positioning tooling 17, and its horn mouth faces the side of the eccentric jaw 28. The horn-shaped channel is divided into an upper channel 22 and a lower channel 23 along its axis; the lower channel 23 is fixedly arranged on the base 1; the upper channel 22 is connected to the pressing block 24 of the pressing mechanism 18 and can move up and down with the pressing block 24 to approach or move away from the lower channel 23. The horn-shaped channel guides one end of the spring cord 25 after rotating 180°, facilitating the spring cord 25 to pass through the second cord-passing hole A2. Dividing it into the upper channel 22 and the lower channel 23 facilitates the upper channel 22 to move up with the pressing block 24 and move away from the lower channel 23 after the buckling is completed, facilitating the picking manipulator 29 to automatically pick up the spring buckle A after the buckling is completed.

[0042] The following specifically describes the entire automatic buckling process:

[0043] First, move the positioning tooling 17 to a position flush with the discharge port of the vibrating bowl, and then the vibrating bowl vibrates and rotates for feeding, arranging the spring buckles A with the front side facing up in a row for sequential feeding, and allowing one spring buckle A to slide onto the positioning tooling 17 through the sequential feeding mechanism 7; subsequently, lower the positioning tooling 17 to a height where the cord-passing hole is flush with the transmission channel; then the turntable 16 drives the spring buckle A to rotate and cooperates with the photoelectric sensor. After the photoelectric sensor passes through the through hole A4 on the side of the spring buckle A, a command is issued to stop the turntable from rotating. At this time, the cord-passing hole is aligned with the transmission channel; then the cylinder above drives the pressing block 24 to press down the spring buckle A; at this time, the wire feeding wheel set starts to operate for feeding the cord. When the head of one end of the spring cord 25 passes through the first cord-passing hole A1 and extends 4 - 5 cm out of the eccentric jaw 28, the jaw clamps the spring cord 25 and moves a certain distance along the slide rail following the cord feeding speed; then the jaw drives one end of the spring cord 25 to rotate counterclockwise by 180°, and at the same time the spring cord cutting device 10 cuts the spring cord 25; after the jaw rotates counterclockwise by 180°, the eccentric jaw 28 immediately drives one end of the spring cord 25 to pass through the second cord-passing hole A2 through the funnel-shaped pipe, completing the buckling process. Then the pressing block 24 of the pressing mechanism 18 moves up and drives the upper channel 22 to move up, and the picking manipulator 29 picks up the spring buckle A with the spring cord 25 threaded through it to complete the picking work.

[0044] This automatic spring buckle threading machine can achieve the automatic transmission of the spring cord 25, the automatic positioning of the spring buckle A, and the cutting of the spring cord 25. It can also rotate one end of the spring cord 25 passing through the first cord threading hole A1 of the spring buckle A by 180 degrees, and then pass it out through the second cord threading hole A2 to complete the threading action, realizing the full automation of the entire threading work, improving production efficiency and reducing cost input.
