Description

[0001] This application is a divisional application of a Chinese patent application with the filing date of July 5, 2023, application number 2023108212943, and invention title "Pilates Fitness Equipment Leather Covering Auxiliary Equipment and Its Auxiliary Method". Technical Field

[0002] The present invention belongs to the technical field of auxiliary equipment for the processing of sports equipment, and in particular relates to a Pilates fitness equipment leather covering auxiliary equipment and its auxiliary method. Background Art

[0003] Pilates wooden ladder barrels are widely used in Pilates fitness equipment.

[0004] As Figure 1-2 shown, such a Pilates wooden ladder barrel 02 is composed of multiple parts, including a fixed frame 021, a ladder frame 022, and a lying barrel assembly 023, etc. The lying barrel assembly 023 includes a lying barrel 024 and two side plates 025 that straddle the lying barrel 024. The lying barrel is a semi-cylinder cut along the axis of the cylinder, and the arc surface on one side faces upward. The arc-shaped structure on the surface of the lying barrel is soft, and it is composed of foaming material 026 attached to the arc-shaped frame and a leather surface layer 027 that covers and fixes the foaming material 026.

[0005] Figure 2 The shown three-dimensional view of the lying barrel 024, that is, the structure of the lying barrel assembly 023 after removing the side plates 025, includes a skeleton 028 and connecting side plates 029. In the process of manufacturing the lying barrel 024, the existing production line requires a large amount of manual operation. This is because when wrapping and fixing the foaming material with the leather surface layer, it is necessary to continuously stretch and tighten the surface material manually. At the same time, manual operation requires the use of pneumatic nails to connect the leather surface layer to the skeleton one by one. During this process, the worker also needs to continuously adjust the position of the lying barrel 024 to ensure that the leather surface layer 027 is symmetrically tightened and pay attention to whether there are wrinkles, and fix it point by point in this way until it is all completed. This production method has a large labor intensity and low production efficiency. At the same time, due to human errors, there may be defects in the appearance effect.

[0006] Generally speaking, the current problems mainly include that during the manufacturing process of the lying barrel 024, the degree of manual intervention is too high, the labor intensity is large and the efficiency is low. At the same time, human factors may also cause defects in the appearance of the product. Summary of the Invention

Place the lying barrel to be covered with leather on the loading and unloading conveyor assembly; b. Start the opening and closing of the two movable clamping blocks to reach the set angle. The lifting mechanism grabs the lying barrel through the transmission of the crowbar and the gear set and the action of the propulsion assembly under the start of the lifting cylinder, and transports and lifts the lying barrel in the loading and unloading conveyor assembly to be supported by the roller support under the drive of the translation mechanism; c. Drive the lower pressing beam plate to move downward until the two clamping seats respectively enter the two connecting side plates of the lying barrel, and perform position correction. Then, clamp the two connecting side plates on both sides, and then the lying barrel rises accordingly, and the two movable clamping blocks return to the flattened position; d. Control the two hinge frames to the flattened state, and control the surface layer clamping member to the open state; e. Move the translation mechanism to drive the surface layer feeding mechanism to reach the telescopic stop at one end, start the power motor to feed, so that the starting head of the leather surface layer is placed down into the clamping area of the surface layer clamping member, then stop the power motor, and start the clamping cylinder to make the surface layer clamping member clamp the starting head of the leather surface layer; f. The translation mechanism moves to the telescopic stop on the other side. At the same time, the power motor starts feeding again to lay the leather surface layer; g. Start the surface layer cutting mechanism to cut off the leather surface layer, and then clamp the material end of the leather surface layer; h. Start the two stretching cylinders on both sides to stretch outwards, so that the leather surface layer to be covered with leather is stretched and flattened; i. Drive the lower pressing beam plate to move downward, place and press the lying barrel onto the fixed clamping block, and then make the two hinge frames rotate upwards around the lying barrel until it completely wraps the lying barrel; j. Gradually make the two movable clamping blocks press the lying barrel covered with the surface layer from both sides. At this time, the surface layer has wrapped the flexible material in a large area and flatly. Then, loosen the two surface layer clamping members and reset the two hinge frames; k. The operator uses fasteners such as staples to connect the leather surface layer to the skeleton, and cuts off the excess material. Finally, the pressing beam plate and the movable clamping block are loosened, and the translation mechanism drives the lifting mechanism to transport the lying bucket with the surface layer covered to the loading and unloading conveyor assembly for output, completing the leather covering work.

[0016] The working method of this newly proposed leather covering auxiliary equipment has the following advantages compared with the prior art: High efficiency: Through automated equipment operation, this method makes the leather covering process faster, thus improving production efficiency. From the start of placing the lying bucket, to the laying and cutting of the surface layer leather, and then to the stretching and covering of the surface layer leather, all are automatically completed by the equipment, greatly reducing the time and labor of manual operation.

[0017] Accuracy: Through precise equipment control and operation, this method can accurately complete the position positioning of the lying bucket, the laying and cutting of the leather surface layer, as well as the stretching and covering of the leather surface layer, thus improving the product quality.

[0019] Convenience: This method integrates all the working steps such as the transportation of the lying bucket, the processing of the leather surface layer, and the covering of the lying bucket, making the whole working process smoother and reducing the complexity of the work.

[0020] Safety: Since all operations are automatically completed by the equipment, it reduces the risk of workers directly contacting the leather and other materials, as well as manually operating the equipment, thus improving the work safety.

[0021] Material saving: Precise cutting and using fasteners to connect the leather surface layer and the skeleton reduce the excess material, thus saving materials.

[0022] Generally speaking, the working method of this newly proposed leather covering auxiliary equipment for Pilates fitness equipment has multiple advantages such as high efficiency, accuracy, flexibility, convenience, safety, and material saving compared with the existing technology.

[0023] Preferably, in step b, the opening and closing angle of the movable clamping block can be set to adapt to lying buckets of different shapes and sizes. The preferred setting of the opening and closing angle of the movable clamping block: This preferred solution increases the adaptability of the equipment, and the opening and closing angle of the movable clamping block can be adjusted according to the different shapes and sizes of the lying buckets. This not only increases the versatility of the equipment, but also reduces the equipment adjustment time caused by different lying bucket sizes, further improving the production efficiency.

[0024] Preferably, in step c, the position correction is completed by the rotation and lateral movement characteristics of the outer cylinder. Preferred position correction: This preferred solution performs position correction through the rotation and lateral movement characteristics of the outer cylinder, greatly improving the accuracy of the position correction of the lying barrel, thereby ensuring that the leather surface layer can accurately cover the lying barrel and improving the quality of the product.

[0025] Preferably, in steps e and f, during the movement of the translation mechanism, the power motor will start and stop as needed to control the laying of the leather surface layer. Preferred movement of the translation mechanism: During the movement of the translation mechanism, the power motor will start and stop as needed to control the laying of the leather surface layer.

Detailed implementation mode

[0033] The following further describes the present invention in combination with the embodiments shown in the drawings. Refer to Figure 1-13 All the drawings; Embodiment 1 Figure 3 What is shown is the auxiliary equipment for covering the skin of the Pilates fitness equipment of the present invention, which mainly includes the following parts: Device frame body 1: It includes four columns 11. Each column serves as a corner support on the ground and slopes upward to form a distal end 12. Each distal end 12 is detachably connected to the middle beam 13. The overall height of the device frame body exceeds the height of an average person to facilitate the operator to overlook the construction.

[0034] Base platform 2: At least part of it is located within the area covered by the device frame body and has a certain height. This platform is preferably a box-shaped frame structure with a space in the middle. The frame can be used for installing relevant mechanisms, and the middle space provides a range of activities for the mechanisms. The base platform is tightly connected to the device frame body.

[0035] Loading and unloading conveyor assembly 3: Its support part is fixed on the ground, and the output end of the conveyor part is close to or enters one end of the base platform.

[0036] Translation mechanism 4: The purpose of this mechanism is to carry multiple functional components. It includes two guide rails 41 fixed on the base platform 2, and these two guide rails are arranged in parallel along the conveying direction of the loading and unloading conveying assembly 3. An installation platform 43 is slidably engaged with the two guide rails 41 through a plurality of sliders 42. The translation power transmission system 44 is used to drive the installation platform 43 to move along the guide rails 41. The translation power transmission system 44 includes racks 45 arranged beside each guide rail 41, gears (not shown in the figure) meshing with the racks 45, bevel gear sets 46 coaxially installed with the gears, a synchronizing shaft 47 connecting the two bevel gear sets 46, and a drive motor 48 fixed on the installation platform 43 and drivingly connected to the synchronizing shaft 47. When the translation mechanism is working, the drive motor 48 starts, driving the two bevel gear sets 46 to rotate synchronously. These two synchronously rotating gears mesh with the racks 45, thereby pushing the installation platform 43 to move linearly.

[0037] Surface layer feeding mechanism 5: The design goal of this mechanism is to replace manual laying of the surface layer. It includes two symmetric center bearing brackets 51 and a feeding rack 52 fixed on the installation platform 43. A feeding roller 53 is rotatably connected between the two bearing brackets 51, and a plurality of transition rollers 54 are rotatably connected between the two feeding racks 52, and at least one transition roller 54 is connected to a power motor 55. The roll-mounted leather surface layer 027 is mounted on the feeding roller 53, and the starting head of the leather surface layer 027 passes through a plurality of transition rollers 54. When the power motor 55 starts, the leather surface layer 027 is unwound or wound through the transition rollers 54.

[0038] Surface layer cutting mechanism 6: The design goal of this mechanism is to replace manual cutting of the surface layer. It consists of a cylinder 61 fixedly installed on the two feeding racks 52. The telescopic free end of the cylinder 61 is provided with a mounting seat 62. A profile guide rail 63 is fixedly arranged between the two mounting seats 62. A sliding tool holder 64 is installed on the profile guide rail 63, and a cutting power transmission system 65 drives the sliding tool holder 64 to move along the profile guide rail 63. The cutting power transmission system 65 can adopt various existing technical forms, such as lead screw motor transmission. A blade is installed on the sliding tool holder 64, and the specific structure of the blade can be any structure form in the prior art and is not shown in the figure. During operation, the cylinder 61 controls the distance between the profile guide rail 63 and the leather surface layer 027. When the distance is suitable for the blade to cut the leather surface layer 027, the cutting power transmission system 65 starts, and the blade cuts the leather surface layer 027 as the sliding tool holder 64 moves.

[0039] The design goal of the locking and positioning device 7 is to lock the lying bucket 024 to be covered with leather, facilitating the leather covering work. See Figure 5-8, this device includes a pressing-down component 71 installed on the middle beam 13 and a clamping component 72 located below the middle beam 13. The clamping component 72 consists of a fixed clamping block 721 directly below the middle beam 13 and two movable clamping blocks 722 respectively located on both sides of the fixed clamping block 721. Both of the two movable clamping blocks 722 are hinged to the frame of the base platform 2 on the side close to the fixed clamping block 721, and also include two cylinders respectively pushing the movable clamping blocks 722 to rotate, namely the first power cylinder 723 and the second power cylinder 724. The pressing-down component 71 is composed of a pressing-down cylinder 711 and a pressing-down beam plate 712 installed at the telescopic free end of the cylinder. The concave arc surfaces of the two movable clamping blocks 722 and a fixed clamping block 721 should match the radian of the lying bucket.

[0040] During the locking and positioning process, whether the lying bucket 024 is skewed is the key to determining whether there will be defects in the covering work. Before this, the lying bucket 024 needs to be detected by sensors and manually adjusted in position according to the actual deviation, which will affect the production efficiency. Therefore, the following optimized design has been carried out: A grasping component 73 with guiding and clamping functions is added to the pressing-down component 71 for grasping and positioning the lying bucket 024. See Figure 6 , the grasping component 73 includes two detachable clamping seats 731, which are fixed on the pressing-down beam plate 712. There is an opening on the lower side of the clamping seat 731, and both sides of the opening mouth have outward-expanded inclined surfaces. The internal dimension of the opening is slightly larger than the plate thickness of the connecting side plate 029. A pressing strip 732 is provided at the bottom of the opening of the clamping seat 731, and pneumatic clamping pieces 733 are provided on both sides of the opening of the clamping seat 731. The distance between the two clamping seats 731 should match the center distance between the thickness directions of the two connecting side plates 029 of the lying bucket 024.

[0041] Utilize the opening and closing characteristics of the movable clamping blocks 722 to make them act as temporary docking points for the lying bucket 024 within a certain range. See Figure 5-6 .

[0042] Roller support components 74 that can provide lateral movement and rotation are added to the arc extension ends of the two movable clamping blocks 722. See Figure 6-7。The roller support member 74 includes a long mandrel 741 with both ends fixed to the movable clamping block 722, and an outer cylinder 742 rotatably sleeved on the long mandrel 741. A plurality of outer cylinders 742 can be provided, and a collar 743 is installed in the middle of each outer cylinder 742. The collar 743 is fixed to the long mandrel 741, and the outer cylinder 742 can slide on the collar 743. The central part of the outer cylinder 742 is a hollow section with a diameter larger than that of the long mandrel 741. At the same time, a compression spring 744 sleeved on the long mandrel 741 is installed at each end of the hollow section. In this way, each outer cylinder 742 can freely move within the compression range of the compression spring 744 on the long mandrel 741, and when the outer cylinder 742 is in an unloaded state, the compression spring 744 can reset it.

[0043] Stretching and covering mechanism 8: The design goal of this mechanism is to flatten and stretch the cut leather surface layer 027 in one go, replacing the manual step-by-step tightening operation, enabling the staff to focus on the fixing work when fixing the surface layer. As Figure 9-12 shown, this mechanism includes two hinge frames 81, which are respectively located on both sides of the fixed clamping block 721 and are coaxially hinged to a movable clamping block 722; each hinge frame 81 has a telescopic stop 82 at one end away from the hinge; two stretching cylinders 83, whose bodies are fixed below the hinge frames 81, and their telescopic parts are fixedly connected to the telescopic stops 82; a third power cylinder 84 and a fourth power cylinder 85, which respectively push the two hinge frames 81 to rotate; a surface layer clamping member 86, which is hinged to the side of each telescopic stop 82 away from the fixed clamping block 721; a clamping cylinder 87, whose body is fixed to the telescopic free end of the stretching cylinder 83, and its telescopic rod is hinged to the surface layer clamping member 86. For optimized design, a guiding mechanism is provided between the hinge frame 81 and the telescopic stop 82, and this guiding mechanism can be a combination of a guide rod and a hole, or other forms, such as a track.

[0044] Lifting mechanism 9: The goal of this mechanism is to cooperate with the translation mechanism 4 to extract the leather-covered barrel 024 to be covered in the loading and unloading transfer assembly 3, and transport it to the locking and positioning mechanism 7 for locking, positioning, and covering. After completion, it is transported back to the loading and unloading transfer assembly 3. In this way, the need for manual handling or other mechanical handling can be replaced.

[0045] The lifting mechanism 9 includes a gear set 91 fixedly installed on the outside of each material rack 52, a bent arm 92 with one end fastened to one of the gears, a sector gear 911 with an extension arm on the other gear, and a pry bar 93 with both ends fastened to the extension arms of the two sector gears 911 respectively. The base body is fixed on the installation platform 43, and the telescopic free end thereof is rotatably sleeved on the pry bar 93 through a support seat by a lifting cylinder 94. The other end of the bent arm 92 is a free end, and a propulsion assembly 95 is installed on the free ends of the two bent arms 92. The propulsion assembly 95 includes a seat body 951, a propulsion cylinder 952 installed in the seat body 951, and a pressing block 953 fixed to the free end of the telescopic rod body of the propulsion cylinder 952.

[0046] The overall working process of the skin covering auxiliary equipment for Pilates fitness equipment is as follows: 1. The lying bucket 024 to be covered with skin is placed in the loading and unloading conveyor assembly 3. At the beginning and end stages of the equipment, this assembly is used to send the lying bucket 024 into and out of the entire skin covering process; 2. Start the opening and closing of the two movable holding blocks 722 to a set angle, which can stably place the lying bucket 024 on the roller support 74 (see Figure 5 ). The lifting mechanism 9 grabs the lying bucket 024 through the transmission of the pry bar 93 and the gear set and the action of the propulsion assembly 95 under the start of the lifting cylinder 94, and transports and lifts the lying bucket 024 in the loading and unloading conveyor assembly 3 to the support of the roller support 74 under the drive of the translation mechanism 4; 3. The pressing beam plate 712 descends under the drive of the pressing cylinder 711 until the two clamping seats 731 respectively enter the two connecting side plates 029 of the lying bucket 024 until the pressing strip 732 abuts against the connecting side plate 029. During this process, the lying bucket 024 corrects its position through the rotation and lateral movement characteristics of the outer cylinder 742 at the temporary docking points supported by the two movable holding blocks 722. Then, the pneumatic clamping pieces 733 on both sides clamp the connecting side plates 029 on both sides, the pressing cylinder 711 drives the upward movement, and the lying bucket 024 rises accordingly, and the two movable holding blocks 722 return to the flattened position; 4. Control the two hinge frames 81 to the flattened state through the corresponding power source, and control the surface layer clamping piece 86 to the open state through the corresponding power source; 5. The translation mechanism 4 moves, driving the surface layer feeding mechanism 5 to the telescopic stop 82 at one end. The power motor 55 starts feeding, and the starting head of the leather surface layer 027 is placed down into the clamping area of the surface layer clamping piece 86. The power motor 55 stops, and the clamping cylinder 87 starts, and the surface layer clamping piece 86 clamps the starting head of the leather surface layer 027; 6. The translation mechanism 4 moves to the telescopic stop 82 on the other side. At the same time, the power motor 55 starts feeding again, and the leather surface layer 027 lays the surface layer along the traveling route. The translation mechanism 4 moves until it is below the telescopic stop 82 on the other side; 7. The surface layer cutting mechanism 6 is activated to cut off the leather surface layer 027. Since the surface layer cutting mechanism 6 is located at a certain distance above the laying of the surface layer, after cutting, the material end will automatically fall into the clamping range of the surface layer clamping member 86 on this side. The clamping cylinder 87 is activated, and the surface layer clamping member 86 clamps the material end of the leather surface layer 027. 8. The two stretching cylinders 83 on both sides are simultaneously activated to stretch outwards, and the leather surface layer 027 to be covered with leather is stretched and flattened. 9. The pressing cylinder 711 drives the pressing beam plate 712 to descend, and the lying barrel 024 is placed and pressed onto the fixed clamping block 721. The two hinge frames 81 are pushed around the lying barrel 024 upwards by the corresponding power cylinders until the lying barrel 024 is completely covered. 10. The two movable clamping blocks 722 are gradually pressed against the lying barrel 024 covered with the surface layer from both sides under the push of the corresponding power cylinders (see Figure 9 ). At this time, the surface layer has wrapped the flexible material 222 in a large area and flatly. Then, the two surface layer clamping members 86 are loosened, and the two hinge frames 81 are reset. 11. At this time, the operator uses fixing parts such as staples to connect the leather surface layer 027 to the skeleton, and cuts off the excess material head after completion. 12. Finally, the pressing beam plate 712 and the movable clamping blocks 722 are loosened, and the translation mechanism 4 drives the lifting mechanism 9 to carry the lying barrel 024 with the surface layer covered to the loading and unloading conveyor assembly 3 for output. In this way, the leather covering work is completed.

[0047] This work process already includes all necessary steps to ensure that the leather surface layer 027 can be correctly covered on the lying barrel 024. In this way, while ensuring efficiency and quality, the complexity of manual operations and labor costs can be reduced.
