[0001] The present application relates to the technical field of strip processing, in particular to a shoulder strap machine. BACKGROUND

[0002] At present, in the production process of underwear bra, the shoulder strap of the bra is sewn by a shoulder strap machine. However, the existing shoulder strap machine has no collecting device in the later stage, and the shoulder strap falls to the ground after being sewn and is randomly stacked on the ground, which needs to be collected and arranged manually, resulting in waste of labor and greatly reduced production efficiency. SUMMARY

[0003] Therefore, in order to overcome the defects of the prior art, the purpose of the present application is to provide a shoulder strap machine capable of automatically collecting shoulder straps, so as to automatically collect and arrange the shoulder straps after being sewn on the shoulder strap machine, and improve the production efficiency.

[0004] In order to achieve the above purpose, the present application adopts the following technical scheme:

[0005] A shoulder strap machine, comprising a rack, a shoulder strap sewing mechanism connected with the rack, and a shoulder strap collecting device, wherein the shoulder strap collecting device comprises a supporting mechanism, a feeding mechanism, and a collecting disc.

[0006] The supporting mechanism is used for supporting the shoulder strap, and comprises a push rod assembly and a first driving mechanism connected with the push rod assembly, wherein the first driving mechanism is used for driving the push rod assembly to rotate.

[0007] The feeding mechanism is used for clamping the shoulder strap and making the shoulder strap fall into the collecting disc, and comprises a clamping jaw, a rotating frame, a sliding assembly connected with the rotating frame, a second driving mechanism connected with the clamping jaw and the rotating frame, and a third driving mechanism connected with the sliding assembly; the clamping jaw is used for clamping the end of the shoulder strap, the push rod assembly is used for supporting the middle part of the shoulder strap, the second driving mechanism is used for driving the clamping jaw to clamp the shoulder strap and driving the rotating frame to lift, thereby lifting the shoulder strap from the push rod assembly and making the shoulder strap located on the rotating frame, and the third driving mechanism is used for driving the sliding assembly to move back and forth, thereby driving the clamping jaw and the rotating frame to move back and forth.

[0008] According to the preferred embodiment of the present application, the feeding mechanism is located above the supporting mechanism and the collecting tray, the supporting mechanism comprises a connecting rod, a swing block and a fixing member rotationally connected with the connecting rod, the fixing member is fixedly connected with the rack, and one end of the connecting rod is fixedly connected with the swing block; the push rod assembly comprises a vertical rod, the other end of the connecting rod is fixedly connected with one end of the vertical rod, and the first driving mechanism is fixedly connected with one end of the swing block, and the first driving mechanism is used to drive the swing block to swing up and down to drive the connecting rod to rotate, thereby driving the vertical rod to rotate. In some embodiments of the present application, the supporting mechanism, the feeding mechanism and the collecting tray are fixedly connected with the rack of the shoulder strap machine, and the supporting mechanism is connected with the rack through the fixing member. The feeding mechanism is located at the uppermost position of the three, facilitating the shoulder strap to fall into the collecting tray; and the collecting tray is close to the fixing member of the supporting mechanism.

[0009] According to the preferred embodiment of the present application, the push rod assembly comprises a first supporting rod used to support the shoulder strap, the first supporting rod is located at the end of the vertical rod away from the first driving mechanism, and the first supporting rod is perpendicular to the vertical rod. One end of the vertical rod is fixedly connected with the connecting rod, the swing block is driven to swing up and down by the first driving mechanism to drive the connecting rod to rotate, thereby driving the vertical rod to rotate. The first supporting rod arranged at the end of the vertical rod away from the connecting rod is used to place the shoulder strap to support the shoulder strap. The first supporting rod is perpendicular to the vertical rod, that is, perpendicular to the conveying direction of the shoulder strap, thereby ensuring that the shoulder strap is horizontally straightened, and avoiding that the first supporting rod is arranged to be inclined to fail to support the shoulder strap.

[0010] According to the preferred embodiment of the present application, the shoulder strap collecting device has a first state and a second state, when the shoulder strap collecting device is in the first state, the vertical rod is arranged to be inclined to the side close to the clamping jaw, the end of the vertical rod away from the first driving mechanism is close to the position where the shoulder strap machine sews the shoulder strap, and the vertical plane where the first supporting rod is located is located on the same plane as the vertical plane where the clamping jaw is located. When the shoulder strap collecting device is in the first state, the shoulder strap is located on the second supporting rod of the rotating frame, at this time, the vertical rod is inclined to the side close to the feeding mechanism, and the first supporting rod is located below the shoulder strap and close to the first end of the shoulder strap without contacting the shoulder strap; in the process of changing from the first state to the second state, the swing block is driven to rotate by the first driving mechanism, thereby driving the connecting rod to rotate, and driving the vertical rod to rotate, in this process, the first supporting rod gradually moves to the direction close to the first driving mechanism until the vertical rod is perpendicular to the horizontal plane, thereby supporting the shoulder strap, at this time (the second state), the horizontal height of the first supporting rod is greater than the horizontal height of the first supporting rod in the first state.

[0011] According to a preferred embodiment of the present application, the second driving mechanism is located between the clamping jaw and the rotating frame, the clamping jaw comprises a first clamping piece and a second clamping piece, the second driving mechanism comprises a rotating shaft, the rotating frame comprises a fixed rod and at least one second supporting rod connected perpendicularly to the fixed rod; the second clamping piece and the fixed rod are fixedly connected to two ends of the rotating shaft respectively, the first clamping piece is parallel to the first supporting rod, and the second clamping piece is parallel to the second supporting rod. In some embodiments of the present application, the rotating frame comprises a plurality of second supporting rods connected perpendicularly to the fixed rod, and each second supporting rod is arranged uniformly. The clamping jaw is used to clamp the shoulder strap when the shoulder strap is transported to the collecting disc to prevent it from falling off; the rotating frame is used to support the shoulder strap after it is clamped to keep the shoulder strap horizontal and prevent it from drooping, thereby facilitating the shoulder strap to be laid flat on the collecting disc when it falls into the collecting disc and avoiding multiple shoulder straps from being wound together. The first clamping piece is fixedly connected to the second driving mechanism and always keeps the same state during the working process, and the first clamping piece is always located above the shoulder strap to facilitate the shoulder strap to be clamped in cooperation with the second clamping piece; and the second clamping piece and the fixed rod are fixedly connected to two ends of the rotating shaft respectively, and when the second driving mechanism drives the rotating shaft to rotate, the second clamping piece and the fixed rod are simultaneously driven to rotate, so that the actions of the second clamping piece and the fixed rod are kept synchronous.

[0012] According to a preferred embodiment of the present application, when the shoulder strap collecting device is in a first state, the second supporting rod is parallel to the first supporting rod, the vertical rod is perpendicular to the horizontal plane, and the distance from the second supporting rod to the collecting disc is greater than the distance from the first supporting rod to the collecting disc; when the collecting device is in a second state, the second supporting rod is perpendicular to the first supporting rod. In some embodiments of the present application, when the collecting device is in the second state, the clamping jaw is released, i.e., the first clamping piece and the second clamping piece are in an open state, the first clamping piece is perpendicular to the second clamping piece, and the second supporting rod of the rotating frame also falls down, i.e., the second supporting rod is perpendicular to the first supporting rod. At this time, the distance from the second supporting rod to the collecting disc is greater than the distance from the first supporting rod to the collecting disc, i.e., the horizontal height of the second supporting rod in the second state is greater than the horizontal height of the first supporting rod, thereby avoiding the shoulder strap from not being able to effectively fall on the second supporting rod of the rotating frame. When the collecting device is in the first state, the clamping jaw is closed, i.e., the second clamping piece is rotated to be attached to the first clamping piece to clamp the shoulder strap between the first clamping piece and the second clamping piece; when the second clamping piece is rotated, the fixed rod and the second supporting rod are also simultaneously rotated, at this time, the second supporting rod is lifted up from the bottom until the second supporting rod is parallel to the first supporting rod, so that the shoulder strap is laid flat on the second supporting rod.

[0013] According to the preferred embodiment of the present application, when the collecting device is in the second state, the head end of the shoulder strap is located on the shoulder strap machine, and the length between the head end of the shoulder strap and the first supporting rod is greater than the length between the head end of the shoulder strap and the second supporting rod closest to the second driving mechanism; this ensures that the second supporting rod can directly support the flat part of the shoulder strap when it is lifted upward, and facilitates the placement of the shoulder strap on the second supporting rod. Otherwise, if the second supporting rod closest to the second driving mechanism is located behind the first supporting rod, the shoulder strap behind the first supporting rod is drooping, and it is difficult for the second supporting rod to lift the shoulder strap at the drooping position and place it on the second supporting rod. The length of the second supporting rod is greater than the length between the shoulder strap and the fixed rod, and the end of the second supporting rod away from the fixed rod is located on a plane lower than the plane on which the first supporting rod is located. This ensures that the second supporting rod can effectively catch the shoulder strap and lay it flat on the second supporting rod when it is lifted upward from the bottom, otherwise, only the head end of the shoulder strap is clamped by the clamping jaw, and the rest of the shoulder strap is in a drooping state, which can cause entanglement when it falls into the collecting tray, and is inconvenient to arrange.

[0014] According to the preferred embodiment of the present application, the sliding assembly includes a sliding rail and a sliding block moving back and forth on the sliding rail, the sliding rail is parallel to the fixed rod, the second driving mechanism is fixedly connected to one end of the sliding block through a connecting block, and the other end of the sliding block is connected to the third driving mechanism, which is used to drive the sliding assembly to move back and forth, thereby driving the clamping jaw and the rotating frame to move towards or away from the collecting tray. In some embodiments of the present application, the collecting tray is located outside the rack of the shoulder strap machine, and the shoulder strap is transported outward by a certain distance by the sliding assembly so that it just falls into the collecting tray, which ensures effective collection of the shoulder strap and facilitates the collection of a large number of shoulder straps placed in the collecting tray. In the present application, the shoulder strap collecting device further includes a first mounting plate and a second mounting plate perpendicular to each other, the bottom surface of the first mounting plate is fixed to the rack of the shoulder strap machine, and the top surface is used to fix the third driving mechanism; the sliding rail is fixed on the second mounting plate to ensure the effective sliding of the sliding block.

[0015] According to the preferred embodiment of the present application, when the shoulder strap collecting device is in the second state, the sliding block is close to the end of the sliding rail away from the collecting tray; and when the feeding mechanism transports the shoulder strap to the collecting tray, the sliding block gradually approaches the other end of the sliding rail.

[0016] According to a preferred embodiment of the present application, the collecting disc comprises a bottom plate and first and second side plates located on both sides of the bottom plate, upper ends of the first and second side plates being located at a plane higher than a plane where the bottom plate is located; the length of the bottom plate is greater than or equal to the length of each shoulder strap. The first and second side plates are arranged to prevent the shoulder straps falling on the bottom plate from falling to both sides; the length of the bottom plate is greater than or equal to the length of each shoulder strap to avoid the shoulder straps from falling on the bottom plate and then partially falling due to insufficient length of the bottom plate, and the shoulder straps gradually fall to the ground due to vibration of the machine.

[0017] With the above technical scheme, compared with the prior art, the shoulder strap machine of the present application has the advantages that: the shoulder strap machine is provided with a shoulder strap collecting device, which can support the shoulder straps by the supporting mechanism during sewing of the shoulder straps, clamp the shoulder straps after sewing of the shoulder straps is completed, and horizontally convey the shoulder straps to above the collecting disc to make the shoulder straps directly fall into the collecting disc to realize automatic collection of the shoulder straps, which is fully automatic and does not need manual collection, thus being beneficial to improving production efficiency, saving human resources, and realizing reasonable utilization of human resources.

DETAILED DESCRIPTION

[0024] In order to make the personnel in the technical field better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person of ordinary skill in the art without creative labor should belong to the protection scope of the present application.

[0025] Reference Figures 1 to 4 The shoulder strap machine of the present embodiment comprises a rack 4, a shoulder strap sewing mechanism 6 connected with the rack 4, and a shoulder strap collecting device 10. The shoulder strap sewing mechanism 6 is used for sewing shoulder straps. The shoulder strap collecting device 10 comprises a support mechanism 1, a feeding mechanism 2, and a collecting disc 3. The support mechanism 1 is used for supporting the shoulder straps so that the shoulder straps are not sagged at some positions. The feeding mechanism 2 is used for clamping the shoulder straps and moving the shoulder straps to the direction of the collecting disc 3 so that the shoulder straps fall into the collecting disc 3. The support mechanism 1, the feeding mechanism 2, and the collecting disc 3 of the present embodiment are fixedly connected with the rack 4.

[0026] The support mechanism 1 of the present embodiment comprises a push rod assembly, a first driving mechanism 12, a connecting rod 13, a fixing piece 14, and a swing block 16. The push rod assembly comprises a vertical rod 11 and a first support rod 15 fixedly connected with the vertical rod 11. The connecting rod 13 is rotationally connected with two fixing pieces 14. The support mechanism 1 is fixedly connected with the rack 4 through the fixing pieces 14. One end of the connecting rod 13 is fixedly connected with the swing block 16, and the other end thereof is fixedly connected with one end of the vertical rod 11. The first driving mechanism 12 is fixedly connected with the middle part of the swing block. Figure 1 and Figure 2As shown, when the collecting device is in the first state, the vertical rod 11 is tilted in the direction close to the feeding mechanism 2, and the end of the vertical rod 11 away from the first driving mechanism 12 is close to the position where the shoulder strap machine sews the shoulder strap. The end of the vertical rod 11 away from the first driving mechanism 12 is fixedly connected to the connecting rod 13, and the other end is vertically connected to the first support rod 15 for supporting the shoulder strap. Since the head end of the shoulder strap is fixed on the shoulder strap machine when the shoulder strap is being sewn, the first support rod 15 is located below the shoulder strap being sewn, close to the head end of the shoulder strap. After starting the first driving mechanism 12, the first driving mechanism 12 drives the pendulum block 16 to swing up and down to drive the connecting rod 13 to rotate, thereby driving the vertical rod 11 to rotate, so that the first support rod 15 is lifted until it is perpendicular to the horizontal plane. At this time, the shoulder strap collecting device is in the second state (as shown in FIG. Figure 3 During this process, the first support rod 15 moves from its starting position toward the first driving mechanism 12 until the upright rod 11 is perpendicular to the horizontal plane, thereby supporting the shoulder strap so that the shoulder strap has a straight section. The horizontal height of the first support rod 15 in the second state is greater than that in the first state.

[0027] The feeding mechanism 2 is fixedly connected to the frame 4 by a first mounting plate 51 and a second mounting plate 52 which are perpendicular to each other. The bottom surface of the first mounting plate 51 is fixedly connected to the frame 4 of the shoulder strap machine. The feeding mechanism 2 includes a clamping jaw, a rotating frame, a second drive mechanism 25 located between the clamping jaw and the rotating frame, a sliding assembly, and a third drive mechanism 28 connected to the sliding assembly. The clamping jaw includes a first clamping piece 21 and a second clamping piece 22; the second drive mechanism 25 includes a rotating shaft 251; the rotating frame includes a fixed rod 23 and five evenly spaced second support rods 24 connected to the fixed rod 23 at right angles. The first clamping piece 21 is fixedly connected to the housing of the second drive mechanism 25, the second clamping piece 22 and the fixed rod 23 are fixedly connected to both ends of the rotating shaft 251 respectively, and the first clamping piece 21 is parallel to the first support rod 15, and the second clamping piece 22 is parallel to the second support rod 24. The sliding assembly includes a slide rail 26 fixed on the second mounting plate 52 and a slider 27 slidably connected to the slide rail 26, and the slide rail 26 is parallel to the fixed rod 23; the second driving mechanism 25 is fixedly connected to one end of the slider 27 through the connecting block 29, and the other end of the slider 27 is connected to the third driving mechanism 28, and the third driving mechanism 28 is fixed on the top surface of the first mounting plate 51.

[0028] When the support mechanism 1 supports the shoulder strap in the first state, the first end of the shoulder strap is located on the shoulder strap machine, and the length between the first end of the shoulder strap and the first support rod 15 is greater than the length between the first end of the shoulder strap and the second support rod 24 closest to the second driving mechanism 25; it is ensured that the second support rod 24 can directly support the flat part of the shoulder strap when it is lifted upward, and the shoulder strap is placed on the second support rod 24. At this time, the length of the second support rod 24 is greater than the length between the shoulder strap and the fixed rod 23, and the plane where the end of the second support rod 24 away from the fixed rod 23 is located is lower than the plane where the first support rod 15 is located. It is ensured that the second support rod 24 can effectively catch the shoulder strap and make the shoulder strap flat on the second support rod 24 when it is lifted upward. When the shoulder strap collecting device is in the second state, the vertical rod 11 is perpendicular to the horizontal plane, and the distance between the second support rod 24 and the collecting disc 3 is greater than the distance between the first support rod 15 and the collecting disc 3, so as to ensure that the shoulder strap on the second support rod 24 can be successfully lifted from the support mechanism 1.

[0029] The second driving mechanism 25 in the embodiment is used to drive the opening and closing of the first clamping piece 21 and the second clamping piece 22, and the lifting and falling of the second support rod 24. When the collecting device is in the second state, the second support rod 24 is perpendicular to the first support rod 15, that is, the clamping jaw is loosened, the first clamping piece 21 and the second clamping piece 22 are in the open state, at this time, the first clamping piece 21 is perpendicular to the second clamping piece 22, and the second support rod 24 of the rotating frame also falls downward, that is, the second support rod 24 is perpendicular to the first support rod 15. When the shoulder strap collecting device is in the second state, the second support rod 24 is parallel to the first support rod 15, that is, the clamping jaw is closed, the second clamping piece 22 is rotated to be attached to the first clamping piece 21, and the shoulder strap is clamped between the first clamping piece 21 and the second clamping piece 22 to prevent the shoulder strap from falling during transportation; when the second clamping piece 22 rotates, the fixed rod 23 and the second support rod 24 also rotate at the same time, at this time, the second support rod 24 is lifted upward until the second support rod 24 is parallel to the first support rod 15, so that the shoulder strap is flat on the second support rod 24, the shoulder strap is kept horizontal, and the shoulder strap is prevented from drooping, which facilitates the shoulder strap to be flat on the collecting disc 3 when the shoulder strap falls into the collecting disc 3, and prevents multiple shoulder straps from being wound together.

[0030] The third driving mechanism 28 of the embodiment is used to drive the sliding block 27 to move back and forth, thereby driving the clamping jaw and the rotating frame to move back and forth, and then making the shoulder strap flat on the rotating frame move to the collecting disc 3 to fall into it. When the collecting device is in the second state, the sliding block 27 is close to the end of the slide rail 26 away from the collecting disc 3; when the feeding mechanism 2 transports the shoulder strap to the collecting disc 3, the sliding block 27 gradually moves from the starting position to the other end close to the slide rail 26.

[0031] The collecting tray 3 comprises a bottom plate 31 and first and second side plates 32 and 33 located on both sides of the bottom plate 31, the upper ends of the first and second side plates 32 and 33 being located at a plane higher than the plane where the bottom plate 31 is located, for blocking the shoulder straps falling on the bottom plate 31 from falling to both sides; the length of the bottom plate 31 is greater than the length of each shoulder strap, so as to avoid the shoulder straps from being partially drooped after falling on the bottom plate 31 due to the insufficient length of the bottom plate 31, and the shoulder straps will gradually fall to the ground with the vibration of the machine. In the embodiment, the length of the first side plate 32 is equal to the length of the bottom plate 31, and the length of the first side plate 32 is greater than the length of the second side plate 33, because the second side plate 33 is close to the connection between the vertical rod 11 and the connecting rod 13, in order to avoid the second side plate 33 from affecting the position of the vertical rod 11 and the connecting rod 13, the length of the second side plate 33 is reduced.

[0032] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
