Description

Technical Field

[0001] This utility model relates to the technical field of bag spring manufacturing equipment, and in particular to a bag spring bag manufacturing equipment. Background Technology

[0002] In the production of mattresses and other furniture products, pocket springs are widely used because they provide excellent independent support. Traditional manufacturing processes typically involve first producing single rows of pocket springs, then assembling multiple rows of pocket springs into the desired spring pack using adhesives or simple stitching. However, the bonding or stitching process makes it difficult to precisely control the spacing between the individual spring strings, resulting in inconsistent and non-standard overall dimensions of the final product, affecting product consistency and subsequent assembly. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a bagged spring pack manufacturing equipment that ensures each row of bagged springs maintains a stable position during transport, guarantees uniform spacing between spring strings, and improves the overall dimensional stability and standardization of the product.

[0004] A bagged spring bag manufacturing apparatus according to a first aspect of the present invention includes a frame, a conveying mechanism, a spacer supply mechanism, a first fabric supply mechanism, a second fabric supply mechanism, and an ultrasonic welding mechanism. The conveying mechanism is disposed on the frame and is used to convey single or multiple rows of bagged springs. The spacer supply mechanism is disposed on the frame and corresponds to the conveying path of the conveying mechanism, and is used to place spacers within the gaps in the fabric between adjacent bagged springs in the bagged spring string. The first fabric supply mechanism is disposed above the conveying path and is used to supply the upper connecting fabric. The second fabric supply mechanism is disposed below the conveying path and is used to supply the lower connecting fabric. The ultrasonic welding mechanism is connected to the frame and includes an ultrasonic upper welding head and an ultrasonic lower welding head that can move in opposite directions. The ultrasonic upper welding head and the ultrasonic lower welding head are configured to clamp and weld the stacked upper connecting fabric, the bag spring string and the lower connecting fabric at positions corresponding to the partition. The partition is used to block the welding energy from penetrating the bag spring string itself, and to make the upper welding part and the lower welding part formed by welding respectively fuse each layer of the upper connecting fabric and each layer of the lower connecting fabric, thereby locking multiple rows of bag springs together as one unit through the upper connecting fabric and the lower connecting fabric.

[0005] The bag spring bag manufacturing equipment according to the embodiments of this utility model has at least the following beneficial effects: The bag spring bag manufacturing equipment of this embodiment, through a precise conveying mechanism and a spacer supply mechanism, ensures that each row of bag springs maintains a stable position during conveying, and accurately places spacers within the gaps between adjacent bag springs. During ultrasonic welding, the spacers play a positioning and supporting role, enabling the upper and lower connecting fabrics to accurately fuse according to predetermined positions during welding, thereby ensuring uniform spacing between spring strings in the final product and improving the overall dimensional stability and standardization of the product. Furthermore, the ultrasonic welding mechanism welds the upper and lower connecting fabrics to multiple rows of bag springs into a single unit. The welded upper and lower welded parts fuse the layers of the upper and lower connecting fabrics, forming a stable connection structure. When the spring bag is locally compressed, the stress can be effectively distributed to the surrounding springs through the upper and lower connecting fabrics, allowing the entire spring bag to bear pressure evenly, thereby improving the overall support performance of the product. Meanwhile, this uniform stress distribution also makes the user feel more comfortable when contacting the spring pack, reducing discomfort caused by excessive localized pressure. Furthermore, compared to traditional manual or semi-manual manufacturing methods, it significantly improves production efficiency and reduces labor costs. At the same time, the automated production process reduces human interference and improves the stability of product quality.

[0006] According to some embodiments of the present invention, the spacer supply mechanism is a mold partition plate, and the mold partition plate is provided with a protrusion array corresponding to the placement positions of all the spacers in the multiple rows of bag spring strings.

[0007] According to some embodiments of the present invention, the partition feeding mechanism includes a vibratory feeder, a linear feeder, and a robotic arm, used to deliver the individual sheet-like partitions one by one and accurately to a designated position.

[0008] According to some embodiments of the present invention, both the first fabric supply mechanism and the second fabric supply mechanism are provided with an unwinding roller and a guide roller. The frame is provided with a tensioning take-up roller. The tensioning take-up roller is located at the rear end of the ultrasonic welding mechanism. The upper connecting fabric and the lower connecting fabric are released through the unwinding roller and guided to the tensioning take-up roller by the guide roller. The tensioning take-up roller is used to overlap one end of the upper connecting fabric and the lower connecting fabric to form a U-shaped bag for accommodating the bag-type spring string.

[0009] According to some embodiments of the present invention, the tensioning take-up roller is equipped with a tension controller, which is one of a magnetic powder brake, a servo motor or a pneumatic brake, used to simultaneously apply and maintain a constant tension to the upper connecting fabric and the lower connecting fabric.

[0010] According to some embodiments of this utility model, the working end face shapes of the ultrasonic upper welding head and the ultrasonic lower welding head are adapted to the upper and lower surface shapes of the partition to ensure that the welding pressure is evenly distributed on the pressure-bearing surface of the partition.

[0011] According to some embodiments of the present invention, the ultrasonic welding mechanism is equipped with two or more sets of ultrasonic transducer systems, which can simultaneously form multiple upper and lower welding parts at different positions within one welding cycle.

[0012] According to some embodiments of the present invention, a visual positioning system disposed upstream of the welding mechanism is also included, which is used to detect the position of the partition and feed it back to the control system to calibrate the welding position.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] Reference Figure 1 , Figure 2 and Figure 3This utility model proposes a bag spring pack manufacturing equipment, including a frame, a conveying mechanism 100, a partition supply mechanism, a first fabric supply mechanism 200, a second fabric supply mechanism 300, and an ultrasonic welding mechanism. Specifically, the frame serves as the supporting framework for the entire equipment, providing stable installation positions for each component. Optionally, the conveying mechanism 100 is horizontally arranged on one side of the frame and adopts a chain drive. Multiple slots are evenly distributed on the chain to support single or multiple rows of bag spring strings 500, ensuring that the bag spring strings 500 maintain a stable position and posture during conveying.

[0021] The spacer supply mechanism is installed on one side of the frame, corresponding to the conveying path of the conveying mechanism 100. The spacer 530 is a plastic sheet with a certain hardness and thickness, and its shape is adapted to the gap between adjacent bag springs in the bag spring string 500. When the conveying mechanism 100 conveys the bag spring string 500 to the corresponding position of the spacer supply mechanism, the spacer supply mechanism pushes the cylinder to accurately place the spacer 530 into the gap between adjacent bag springs in the bag spring string 500. The movement of the cylinder is precisely controlled by the PLC control system to ensure that the spacer 530 can be accurately placed in each gap, and that the force and position of placement are consistent.

[0022] The first fabric supply mechanism 200 and the second fabric supply mechanism 300 are respectively located above and below the conveying path. The first fabric supply mechanism 200 stores the upper connecting fabric 510 via a roller driven by a motor, which evenly lays the upper connecting fabric 510 above the bagged spring string 500 being conveyed. The second fabric supply mechanism 300 operates on the same principle as the first fabric supply mechanism 200, laying the lower connecting fabric 520 below the bagged spring string 500. Both the upper connecting fabric 510 and the lower connecting fabric 520 are multi-layer composite fabrics with a certain degree of flexibility and strength to meet welding and usage requirements.

[0023] The ultrasonic welding mechanism is connected to the frame. The upper ultrasonic welding head 410 and the lower ultrasonic welding head 420 are driven by cylinders to move in opposite directions. When the conveying mechanism 100 transports the bagged spring string 500, with the spacer 530 placed and the upper connecting fabric 510 and lower connecting fabric 520 laid out, to the corresponding position of the ultrasonic welding mechanism, the PLC control system issues a command, and the cylinder pushes the upper ultrasonic welding head 410 and the lower ultrasonic welding head 420 downward and upward, respectively, clamping the stacked upper connecting fabric 510, bagged spring string 500, and lower connecting fabric 520. At this time, the ultrasonic generator generates a high-frequency vibration signal, which is converted into mechanical vibration by the transducer, and then the vibration amplitude is amplified by the amplitude transformer and transmitted to the upper ultrasonic welding head 410 and the lower ultrasonic welding head 420. At the position corresponding to the spacer 530, the ultrasonic energy causes friction and heat generation at the contact surface of the upper connecting fabric 510 and the lower connecting fabric 520, thereby causing the fabric molecules to fuse together. The spacer 530 serves to prevent welding energy from penetrating the fabric of the bag spring string 500, ensuring that the welding process only occurs between the upper connecting fabric 510 and the lower connecting fabric 520, without damaging the bag spring string 500. After welding, the ultrasonic upper welding head 410 and the ultrasonic lower welding head 420 separate under the action of a cylinder, and the conveying mechanism 100 continues to transport the welded bag spring pack to the next process. The upper and lower welded parts formed by welding respectively fuse the layers of the upper connecting fabric 510 and the layers of the lower connecting fabric 520, forming a stable overall structure that interlocks multiple rows of bag spring strings 500 into one unit.

[0024] It is understood that the bag spring manufacturing equipment of this embodiment, through the precise conveying mechanism 100 and the spacer supply mechanism, can ensure that each row of bag spring strings 500 maintains a stable position during the conveying process, and accurately places the spacers 530 in the gaps between adjacent bag springs. During the ultrasonic welding process, the spacers 530 play a role in positioning and support, enabling the upper connecting fabric 510 and the lower connecting fabric 520 to be accurately fused in the predetermined positions during welding, thereby ensuring that the spacing between each spring string in the final product is uniform and consistent, improving the overall dimensional stability and standardization of the product. Furthermore, the ultrasonic welding mechanism welds the upper connecting fabric 510 and the lower connecting fabric 520 to multiple rows of bag spring strings 500 into a whole. The upper and lower welded parts formed by welding fuse the layers of the upper connecting fabric 510 and the lower connecting fabric 520 together, forming a stable connection structure. When the spring pack is locally compressed, the stress can be effectively distributed to the surrounding springs through the upper connecting fabric 510 and the lower connecting fabric 520, allowing the entire spring pack to bear the pressure evenly, thereby improving the overall support performance of the product. At the same time, this uniform stress distribution also makes the user feel more comfortable when contacting the spring pack, reducing discomfort caused by excessive local pressure. Furthermore, compared to traditional manual or semi-manual manufacturing methods, this significantly improves production efficiency and reduces labor costs. Simultaneously, the automated production process reduces interference from human factors, improving the stability of product quality.

[0025] Reference Figure 3 The bagged spring pack of this embodiment includes multiple spacers 530. In some embodiments, the spacer supply mechanism employs a mold partition. The mold partition is rectangular in shape and made of high-strength, wear-resistant engineering plastic to ensure it is not easily deformed or damaged during long-term use. The mold partition features a carefully designed array of protrusions corresponding to the placement positions of all spacers 530 in the multi-row bagged spring strings 500. These protrusions are cylindrical, with a diameter matching the width of the fabric gap between adjacent bagged springs in the bagged spring strings 500, and a height slightly less than the depth of the fabric gap, ensuring that the spacers 530 can be smoothly inserted into the gap without compressing the bagged springs. In specific applications, when the conveying mechanism 100 transports the multi-row bagged spring strings 500 to the corresponding position of the spacer supply mechanism, the mold partition is driven downwards by a cylinder, causing the protrusion array to accurately insert into the fabric gap of the bagged spring strings 500, pressing the spacers 530 into their corresponding positions. Subsequently, the mold partition is lifted upwards by the cylinder, completing the placement process of the spacers 530. The entire process is precisely controlled by a PLC control system to regulate the speed and stroke of the cylinders, ensuring that each 530 partition can be accurately placed.

[0026] Understandably, the raised array on the mold partition corresponds one-to-one with the placement positions of the spacers 530 of the multi-row bagged spring strings 500. This allows multiple spacers 530 to be accurately placed in their designated positions at once, avoiding potential positional deviations that might occur with individual placement. This significantly improves the accuracy and efficiency of spacer 530 placement. The high precision of the spacer 530 placement enables subsequent welding processes to be performed more accurately, ensuring uniform spacing between spring strings in each spring pack. This improves the overall dimensional stability and standardization of the product, facilitating consistent product quality control.

[0027] In other embodiments, the separator supply mechanism consists of a vibratory feeder, a linear feeder, and a robotic arm. The vibratory feeder is circular with an internal spiral track. Separators 530 are placed inside the vibratory feeder, and the vibration of the vibratory feeder causes the separators 530 to move upward along the spiral track, achieving initial sorting and separation. The linear feeder is connected to the outlet end of the vibratory feeder. It is a long strip structure with guide grooves, capable of conveying the separators 530 from the vibratory feeder one by one and in an orderly manner to the designated position. The linear feeder has an internal electromagnetic vibration device. By adjusting the vibration frequency and amplitude, it ensures that the separators 530 are conveyed forward at a stable speed and posture. The robotic arm is installed at the end of the linear feeder. It adopts a three-axis or more axis motion structure, which can precisely control the position and posture of the end effector. When the separators 530 are conveyed to the end of the linear feeder, the robotic arm accurately grasps the separators 530 through a vision recognition system and precisely places them into the gap between adjacent bag springs in the bag spring string 500. The entire process is coordinated and controlled by a PLC control system to ensure that the actions of each component are accurate and error-free.

[0028] Understandably, the combination of the vibratory feeder and the linear feeder enables the automatic sorting and orderly conveying of the spacers 530, while the robotic arm possesses high-precision gripping and delivery capabilities, ensuring that each spacer 530 is accurately placed in its designated position, thus improving the accuracy and reliability of spacer placement. Furthermore, this spacer supply mechanism is highly flexible; by adjusting the parameters of the vibratory feeder, the speed of the linear feeder, and the movement trajectory of the robotic arm, it can adapt to the placement requirements of spacers 530 for bagged spring strings 500 of different specifications and sizes, improving the equipment's versatility and production adaptability.

[0029] Reference Figure 1In the embodiments of this utility model, the first fabric supply mechanism 200 and the second fabric supply mechanism 300 have the same structure. Each mechanism is equipped with an unwinding roller 610 and a guide roller 620. The unwinding roller 610 is used to store the upper connecting fabric 510 or the lower connecting fabric 520, and is driven to rotate by a motor to release the fabric. The guide roller 620 serves to guide the direction of the fabric, so that the fabric can be transported along a predetermined path. Further, a tensioning take-up roller is provided on the frame, which is located at the rear end of the ultrasonic welding mechanism. After the upper connecting fabric 510 and the lower connecting fabric 520 are released from their respective unwinding rollers 610, they are guided by the guide roller 620 and finally converge at the tensioning take-up roller. The tensioning take-up roller is driven to rotate by a motor, overlapping one end of the upper connecting fabric 510 and the lower connecting fabric 520 to form a U-shaped bag, which can just accommodate the bagged spring string 500. When the conveying mechanism 100 conveys the bagged spring string 500 into the U-shaped cloth bag, the fabric can fit tightly against the bagged spring string 500, preparing it for subsequent welding.

[0030] Understandably, by setting up the unwinding roller 610, guide roller 620, and tensioning take-up roller, the automatic release, guidance, and forming of the upper connecting fabric 510 and the lower connecting fabric 520 are achieved, forming a U-shaped bag to accommodate the bagged spring string 500. This simplifies the fabric supply and forming process and improves production efficiency. The tensioning take-up roller ensures that the upper connecting fabric 510 and the lower connecting fabric 520 maintain a certain tension, allowing the fabric to tightly adhere to the bagged spring string 500 when forming the U-shaped bag, preventing fabric looseness or wrinkles. This is beneficial for subsequent welding quality and improves the overall product quality.

[0031] In some embodiments, the tensioning take-up roller is equipped with a tension controller, here a magnetic powder brake is selected as the tension controller. The magnetic powder brake is mounted on the drive shaft of the tensioning take-up roller and consists of an active part, a driven part, and magnetic powder. When current passes through the coil of the magnetic powder brake, a magnetic field is generated. Under the action of the magnetic field, the magnetic powder forms a magnetic powder chain, connecting the active part and the driven part, thereby realizing the transmission of torque. By adjusting the magnitude of the input current, the torque generated by the magnetic powder brake can be controlled, thereby simultaneously applying and maintaining a constant tension on the upper connecting fabric 510 and the lower connecting fabric 520. During the production process, the PLC control system adjusts the input current of the magnetic powder brake in real time according to factors such as the material, thickness, and conveying speed of the fabric, ensuring that the fabric maintains a stable tension throughout the entire production process.

[0032] Reference Figure 1The working end faces of the ultrasonic upper welding head 410 and ultrasonic lower welding head 420 are carefully designed to match the shapes of the upper and lower surfaces of the partition 530. For example, if the upper and lower surfaces of the partition 530 are flat, the working end faces of the ultrasonic upper welding head 410 and ultrasonic lower welding head 420 are also designed to be flat; if the upper and lower surfaces of the partition 530 are curved, the working end faces are also designed to be curved accordingly. Specifically, during welding, the ultrasonic upper welding head 410 and ultrasonic lower welding head 420 move towards each other under the drive of a cylinder, clamping the stacked upper connecting cloth 510, the bagged spring string 500, and the lower connecting cloth 520. Because the working end face shapes match the shapes of the upper and lower surfaces of the partition 530, the welding pressure can be evenly distributed on the pressure-bearing surface of the partition 530, so that the welding energy is evenly transferred to the contact surface of the upper connecting cloth 510 and the lower connecting cloth 520, thereby achieving a good welding effect. Understandably, the shape of the working end face matches the shapes of the upper and lower surfaces of the spacer 530, enabling uniform distribution of welding pressure and avoiding problems such as weak welds, localized overheating or undercooling caused by uneven pressure. This ensures the uniformity and stability of the weld quality. The uniform weld quality also makes the connection between the upper connecting fabric 510, the lower connecting fabric 520, and the pocket spring string 500 more robust, allowing the product to better withstand pressure and stress during use, thus improving the overall support performance and durability of the product.

[0033] In some embodiments, the ultrasonic welding mechanism is equipped with two sets of ultrasonic transducer systems. Each set of ultrasonic transducer systems includes an ultrasonic generator, a transducer, an amplitude transformer, an ultrasonic upper welding head 410, and an ultrasonic lower welding head 420. Specifically, during the welding process, when a welding cycle begins, both sets of ultrasonic transducer systems start simultaneously. The ultrasonic generator generates high-frequency vibration signals, which are transmitted to the corresponding transducers. The transducers convert the electrical signals into mechanical vibrations, which are then amplified by the amplitude transformer and transmitted to the ultrasonic upper welding head 410 and the ultrasonic lower welding head 420. The two sets of ultrasonic transducer systems can simultaneously form multiple upper and lower welding parts at different positions within a welding cycle. For example, welding can be performed simultaneously at multiple critical connection positions of multiple rows of bag spring strings 500, greatly shortening the welding time and improving production efficiency.

[0034] Optionally, in some embodiments, a visual positioning system is provided upstream of the welding mechanism. The visual positioning system mainly consists of a camera, a light source, and an image processing system. The camera is mounted on a frame, with its lens aimed at the position of the conveyed bagged spring string 500 and the spacer 530, enabling real-time image capture. The light source provides sufficient illumination to the camera, ensuring clear and accurate images. The image processing system analyzes and processes the images captured by the camera, detecting the position information of the spacer 530 through an image recognition algorithm. When a deviation in the position of the spacer 530 is detected, the image processing system feeds back the deviation information to the control system. The control system adjusts the position of the conveying mechanism 100 or the parameters of the welding mechanism in a timely manner based on the feedback information, calibrating the welding position to ensure that the welding process can be accurately performed at the position corresponding to the spacer 530.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
