Description

Technical Field

[0001] This utility model relates to the field of sewing equipment, and in particular to a rotary gantry sewing machine with a swivel needle head. Background Technology

[0002] Template sewing is a sewing process that uses automated equipment to cut grooves into an acrylic sheet to the required dimensions, allowing for sewing along the grooved path. It is particularly useful in the automotive interior and luggage industries, where the cut pieces are relatively large. Template sewing significantly improves production efficiency and quality consistency. This modular sewing method simplifies and standardizes complex processes for factories, increasing efficiency, reducing defect rates, improving quality and production time stability, and reducing reliance on highly skilled workers.

[0003] Existing template sewing machines have a fixed sewing machine. The sewing template is moved horizontally to move the sewing machine table and sews according to the grooved path of the sewing template. However, with this structure, once sewing is completed, the machine needs to be stopped to replace the sewing template, which affects work efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a rotary gantry sewing machine with a swivel needle head. It adopts a first exchange mechanism to realize the automatic feeding of the sewing template, replacing manual replacement. Combined with the automatic XZ axis movement sewing of the sewing machine, it can realize automated sewing and effectively improve the sewing efficiency and the quality of product sewing.

[0005] To achieve the above objectives, this utility model provides a rotary gantry sewing machine with a swivel needle head, comprising:

[0006] The machine base is provided with a working platform and a gantry beam that is horizontally arranged above the working platform;

[0007] A sewing machine, wherein a first X-axis moving mechanism is provided on the gantry beam, and the first X-axis moving mechanism is connected to the sewing machine;

[0008] A sewing template, wherein the sewing template is provided with a sewing area for placing materials, and at least two sewing stations arranged one in front of the other are formed on the work platform, the two sewing stations being used to place the sewing template;

[0009] A first exchange mechanism is provided on the machine base. The first exchange mechanism includes a first exchange motor and a conveying component connected to the first exchange motor. The conveying component is used to move the sewing template from the rear to the square sewing station for sewing.

[0010] Furthermore, the conveying assembly includes first slide rails disposed on both sides of the sewing station, first support seats slidably disposed on the first slide rails, and a first clamping beam fixedly connected to the first support seats. The first clamping beam is horizontally disposed above the sewing station. The first switching motor is connected to a first linkage component, and the first support seats are connected to the first switching motor through the first linkage component. A plurality of first clamping components are disposed on the first clamping beam. Through the sliding cooperation between the first slide rails and the first support seats, combined with the belt drive system driven by the first switching motor, the first clamping beam can move quickly and smoothly, improving the accuracy of cooperation with the sewing machine. At the same time, it can quickly change the template, ensuring accurate positioning of the template change and reducing errors caused by manual intervention.

[0011] Furthermore, the first clamping assembly includes a first clamping main seat fixed to the first clamping crossbeam and a first clamping cylinder disposed on the first clamping main seat, the first clamping cylinder being connected to a clamping member; a clamping column cooperating with the clamping member is provided on the sewing template, a first groove matching the shape of the clamping column is provided at the front end of the first clamping main seat, the middle part of the clamping member is rotatably disposed on the first clamping main seat via a movable shaft, one end of the clamping member is a barbed clamping part, the clamping part is positioned above the first groove, and the other end of the clamping member away from the clamping part is connected to the first clamping cylinder. The first groove at the front end of the first clamping main seat matches the shape of the clamping column on the sewing template, ensuring accurate alignment during clamping, and the barbed clamping part of the clamping member can firmly engage the clamping column, preventing movement and template loosening due to vibration or pulling during sewing, thus affecting sewing quality.

[0012] Furthermore, it also includes an auxiliary component, which is fixed above the first clamping main seat, so that the clamping member is placed between the auxiliary component and the first clamping main seat. The auxiliary component is provided with a second groove that matches the first groove. The auxiliary component ensures that the clamping column is constrained both vertically when clamped, avoiding displacement caused by vibration or tension during sewing and movement, thereby improving the quality of sewing.

[0013] Furthermore, two sets of conveying assemblies are movably mounted on the machine base, located on opposite sides of the sewing station. Each set of conveying assemblies includes a second conveying main seat fixed to the machine base, a first switching motor fixed to the second conveying main seat, and a ring-shaped transmission track formed on the second conveying main seat. The transmission track is connected to the first switching motor via a first transmission shaft. Transmission racks that mesh with the transmission track are located on both sides of the sewing template. Through the cooperation of the transmission track and the transmission racks, uninterrupted conveying of the sewing template for sewing can be achieved. The toothed transmission method provides precise, slip-free displacement, further ensuring sewing accuracy.

[0014] Furthermore, it also includes a second drive shaft and a third drive shaft, which are horizontally arranged on both sides of the lower end of the second conveyor seat, forming a triangular distribution with the first drive shaft, so that the transmission track forms a closed triangular ring. The second and third drive shafts increase the meshing length between the transmission track and the transmission rack, improving the stability of the transmission.

[0015] Furthermore, it also includes a gear set, which comprises a first transmission gear linked to the first exchange motor and a second transmission gear linked to the first transmission shaft. The first transmission gear meshes with the second transmission gear, and the diameter of the second transmission gear is larger than that of the first transmission gear. The gear set enhances the output power of the first exchange motor, ensuring the normal movement of the sewing template.

[0016] Furthermore, the sewing machine includes an upper sewing head and a lower sewing head. The first X-axis moving mechanism includes an X-axis moving motor, a first transmission belt, a second transmission belt, a second slide rail, and a third slide rail. The second slide rail is fixedly connected to the bottom of the gantry beam, and the third slide rail is fixedly connected to the machine base and located directly below the gantry beam. A first sewing head main seat is connected to the second slide rail. A Z-axis mechanism is provided on the first sewing head main seat, which is connected to the upper sewing head. A second sewing head main seat is slidably connected to the third slide rail. The lower sewing head is fixedly connected to the second sewing head main seat and cooperates with the upper sewing head. The first transmission belt is set on the gantry beam through a second driving wheel and a third driven wheel. The second transmission belt is set on the machine base through a third driving wheel and a fourth driven wheel. The second driving wheel and the third driving wheel are linked through a sewing head drive shaft. The X-axis moving motor is connected to the sewing head drive shaft, thereby realizing the synchronous displacement of the upper and lower sewing heads. The upper and lower sewing heads are used in a coordinated sewing mode. The upper sewing head moves vertically through the Z-axis mechanism, while the lower sewing head is fixed to the main seat of the second sewing head. The two move synchronously in the X-axis direction to ensure alignment accuracy.

[0017] Furthermore, the Z-axis mechanism includes a Z-axis motor fixed to the main seat of the first sewing head. The Z-axis motor is connected to a reducer, and the reducer is connected to the upper sewing head via a worm gear to achieve Z-axis movement of the upper sewing head. This enables the upper sewing head to move up and down, ensuring smooth sewing.

[0018] Furthermore, a sewing groove is formed between the two sewing stations, which is used for the coordinated operation of the upper and lower sewing heads.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This utility model adopts a gantry beam structure and is equipped with a first X-axis moving mechanism to realize the synchronous X-axis movement of the upper and lower sewing heads, which can improve the sewing operation with precision and efficiency. At the same time, the upper sewing head achieves vertical movement through the Z-axis mechanism, which is beneficial for coordinating the replacement of sewing templates, making it more practical.

[0021] This utility model employs a first exchange mechanism to input the sewing template. This first exchange mechanism can achieve two methods: 1. A clamping conveying method using a first slide rail and a first clamping beam. Specifically, a first exchange motor drives the first clamping beam to slide back and forth on the first slide rail. The first clamping component on the first clamping beam clamps and locks the sewing template, and then drags the sewing template to the sewing area to cooperate with the sewing machine for sewing operations, thereby realizing automated sewing template replacement and sewing operations. 2. A transmission track and transmission rack work together to achieve uninterrupted conveying of the sewing template for sewing operations.

[0022] In summary, this utility model can move the sewing template from the material feeding station to below the sewing machine for sewing operations, eliminating the need for manual intervention, reducing the error rate of manual operation, improving the level of automation in production, optimizing equipment space utilization, reducing equipment and labor costs, meeting the production needs of enterprises, and possessing strong market competitiveness and adaptability.

[0039] Please see Figures 1 to 10 The present invention provides a rotary gantry sewing machine with a swivel needle head.

[0040] Example 1

[0041] The rotating gantry sewing machine of this embodiment 1 includes: a machine base 1, a sewing machine 2, a sewing template 3, and a first exchange mechanism 4 provided on the machine base 1.

[0042] like Figure 1 As shown, a work platform 11 and a gantry beam 12 are provided on the base 1. A first X-axis moving mechanism 5 is provided on the gantry beam 12, which is connected to the sewing machine 2. At least two sewing stations 111 are formed on the work platform 11, which are arranged one in front of the other. The two sewing stations 111 are used to place the sewing template 3. The sewing template 3 is provided with a sewing area 31 for placing materials.

[0043] Specifically, such as Figure 1 and Figure 2As shown, in this embodiment, the sewing machine 2 includes an upper sewing head 21 and a lower sewing head 22. A sewing groove 112 is formed between the two sewing stations 111. The sewing groove 112 is used for the coordinated operation of the upper sewing head 21 and the lower sewing head 22.

The first transmission belt 52 is set on the gantry beam 12 through the provided second driving wheel 521 and the third driven wheel 522. The second transmission belt 53 is set on the machine base 1 through the provided third driving wheel 531 and the fourth driven wheel 532. The second driving wheel 521 and the third driving wheel 531 are linked through the provided machine head transmission shaft 511. The X-axis moving motor 51 is connected to the machine head transmission shaft 511, thereby realizing the synchronous displacement of the upper machine head 21 and the lower machine head 22.

[0044] Preferably, in this embodiment, the Z-axis mechanism 56 includes a Z-axis motor 561 fixed on the first headstock 541. The Z-axis motor 561 is connected to a reducer 562. The reducer 562 is connected to the upper headstock 21 through a worm gear 563 to realize the Z-axis movement of the upper headstock 21, thereby realizing the up and down movement of the upper headstock 21 and ensuring the smoothness of sewing.

[0045] In this embodiment, the sewing template 3 is alternately operated at the sewing station through the first exchange mechanism 4. The first exchange mechanism 4 includes a first exchange motor 41 and a conveying component 6 connected to the first exchange motor 41. The conveying component 6 is used to transfer the sewing template 3 to the sewing station 111 for sewing.

[0046] like Figure 1 and Figure 3As shown, the conveying assembly 6 in this embodiment includes a first slide rail 61 disposed on both sides of the sewing station 111, a first support seat 62 slidably disposed on the first slide rail 61, and a first clamping beam 63 fixedly connected to the first support seat 62. The first clamping beam 63 is horizontally disposed above the sewing station 111. A first switching motor 41 is connected to a first linkage assembly 65. The first support seat 62 is connected to the first switching motor 41 through the first linkage assembly 65. A plurality of first clamping assemblies 64 are disposed on the first clamping beam 63. In this embodiment, a total of three sets of first clamping assemblies 64 are disposed. The first linkage assembly described above... 65 includes two third transmission belts 651 set on both sides of the workstation. The first support base 62 is connected to the third transmission belt 651. The two ends of each set of third transmission belts 651 are linked by a rotating wheel 652. One rotating wheel 652 is connected to the first exchange motor 41 to realize power output. Of course, two first exchange motors 41 can also be set at the same time to provide power to the third transmission belts 651 on both sides simultaneously. The rotating wheel 652 on the other side away from the first exchange motor 41 is connected to a first linkage shaft 653, thereby realizing the synchronous linkage of the two sets of third transmission belts 651.

[0047] like Figure 4 and Figure 5 As shown, the first clamping assembly 64 includes a first clamping main seat 641 fixed to the first clamping crossbeam 63 and a first clamping cylinder 642 disposed on the first clamping main seat 641, the first clamping cylinder 642 being connected to a clamping member 643; as Figure 6 As shown, a clamping column 32 that cooperates with the clamping member 643 is provided on the sewing template 3. A first groove 6411 matching the shape of the clamping column 32 is provided at the front end of the first clamping main seat 641. The middle part of the clamping member 643 is rotatably mounted on the first clamping main seat 641 via a movable shaft. One end of the clamping member 643 is a barb-shaped clamping part 6431, which is positioned above the first groove 6411. When the clamping member 643 rotates around the shaft, the clamping part 6431 can extend into the top of the first groove 6411 to clamp the column. The other end of the clamping member 643 away from the clamping part 6431 is connected to the first clamping cylinder 642. Preferably, this embodiment also includes an auxiliary component 644 and a sensor 645. The auxiliary component 644 is fixedly connected above the first clamping main seat 641, and the sensor 645 is installed above the first clamping main seat 641, so that the clamping component 643 is placed between the auxiliary component 644 and the first clamping main seat 641. A second groove 6441 matching the first groove 6411 is provided on the auxiliary component 644. The auxiliary component 644 ensures that the clamping column 32 is constrained both vertically when clamped, avoiding displacement caused by vibration or tension during sewing and movement, thereby improving the sewing quality.

[0048] In addition, to prevent the slide rail from being contaminated by dust and other contaminants, dustproof pads 7 can be installed on the gantry beam 12 and the machine base.

[0049] Brief description of the working principle of this embodiment: This utility model is equipped with two sewing stations. The front sewing station is used for material feeding. The sewing machine 2 is located between the two sewing stations. During equipment operation, the material is placed on the sewing template 3 in advance, and then the sewing template 3 is placed in the front sewing station. The first exchange motor 41 starts, driving the two sets of first transmission belts 52 to rotate synchronously, thereby driving the first clamping beam 63 to move to the front sewing station. During the movement, the clamping member 643 handles the outside of the first groove 6411. When the first clamping beam 63 reaches the set position, the first clamping column 32 inserts into the first groove 6411 and the second groove 6441. At this time, the first clamping cylinder 642 starts to push the clamping member 643 to rotate, so that the clamping... Part 6431 can clamp the column 32 tightly, realizing the linkage of the sewing template 3. Then, the first exchange motor 41 rotates in reverse, and with the first clamping beam 63, it drags the sewing template 3 to the sewing station on the rear side. When the sewing template 3 reaches the position of the sewing machine 2, the sewing machine 2 performs sewing operations with the cooperation of the first X-axis moving mechanism 5 and the Z-axis mechanism 56 until the sewing operation is completed. The first exchange motor 41, with the cooperation of the first clamping beam 63, completely pulls the sewing template 3 to the sewing station behind, and the first clamping cylinder 642 resets, so that the clamping part 6431 releases the column 32. The sewing template 3 that has been sewn is then unloaded manually or with the help of other equipment. At the same time, a new sewing template 3 is also placed in the front sewing station. The above actions can be repeated.

[0050] Example 2

[0051] like Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that two sets of conveying components 6 are movably arranged on the machine base 1, and the two sets of conveying components 6 are respectively arranged on both sides of the sewing station 111, wherein... Figure 9 and Figure 10 As shown, each conveying assembly 6 includes a second conveying main seat 66 fixed to the base 1, a first switching motor 41 fixed to the second conveying main seat 66, and a ring-shaped transmission track 67 formed on the second conveying main seat 66. The transmission track 67 is connected to the first switching motor 41 through a first transmission shaft 411. Figure 8 As shown, transmission racks 33 that mesh with the transmission track 67 are provided on both sides of the sewing template 3. Through the cooperation of the transmission track 67 and the transmission racks 33, the sewing template 3 can be continuously transported for sewing, and the toothed transmission method can provide precise displacement without slippage, further ensuring the accuracy of sewing.

[0052] To improve the connection stability between the transmission track 67 and the transmission rack 33, this embodiment also includes a second transmission shaft 68 and a third transmission shaft 69. The second transmission shaft 68 and the third transmission shaft 69 are horizontally arranged on both sides of the lower end of the second conveyor seat 66, forming a triangular distribution with the first transmission shaft 411, so that the transmission track 67 forms a closed triangular ring. In particular, gears that mesh with the transmission track are provided on the first transmission shaft 411, the second transmission shaft 68 and the third transmission shaft 69. The second transmission shaft 68 and the third transmission shaft 69 can increase the meshing length between the transmission track 67 and the transmission rack 33, thereby improving the stability of the transmission.

[0053] To improve the power stability of the first exchange motor 41, this embodiment also includes a gear set 60. The gear set 60 includes a first transmission gear 601 that is linked to the first exchange motor 41 and a second transmission gear 602 that is linked to the first transmission shaft 411. The first transmission gear 601 and the second transmission gear 602 mesh, and the diameter of the second transmission gear 602 is larger than that of the first transmission gear 601. The gear set 60 improves the output power of the first exchange motor 41, ensuring the normal movement of the sewing template 3.

[0054] The working principle of this utility model is briefly described. The operation of the sewing machine 2 in this embodiment is the same as that in embodiment 1, so it will not be repeated. In this embodiment, a conveyor belt and a transmission rack 33 are used to replace the sewing template 3. During operation, the material is first loaded into the sewing area 31 of the sewing template 3. Then, the first exchange motor 41 is started to drive the transmission belt 67 to drive forward. Then, the sewing template 3 is pushed forward so that the transmission rack 33 and the transmission belt 67 mesh (or they can mesh first and then start the first exchange motor 41). The transmission belt 67 drives the sewing template 3 to move towards the sewing machine 2 through the transmission rack 33, and performs sewing operations in cooperation with the sewing machine 2. When a sewing template 3 finishes sewing, a new sewing template 3 can be continuously pushed forward, so as to achieve uninterrupted sewing operations.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
