[0002] The bagged spring string is a core component commonly used in mattress and furniture manufacturing, which mainly functions to provide support, shock absorption and comfort for the human body or objects, and each spring is individually packaged in a non-woven fabric bag to form an independent unit. The bagged spring string production equipment usually first welds the non-woven fabric longitudinally into a cloth bag, then sends the compressed spring into the cloth bag, and packages the spring in an independent bag chamber by transversely welding the cloth bag, so that multiple continuous independent bagged springs form a bagged spring string.

[0003] With the increasing demand of consumers for sleep quality, bagged spring mattresses dominate the mid-to-high-end market. In the bagged spring string production process, the reasonable design of the conveying device is crucial to improving production efficiency and product quality.

[0004] At present, the common conveying methods on the spring production line mainly include single chain conveying and straight rail conveying: the single chain conveying usually takes the spring output by the spring winding machine through a single chain and directly conveys it to the next process; the straight rail conveying guides the spring to slide to the designated position by using the slide rail.

[0005] However, when facing the production demand of multiple heads or multiple specifications of springs, it is difficult to realize the orderly merging and conveying of the springs, which can easily lead to mutual interference or accumulation of the springs, thereby affecting the production efficiency and product quality.

DETAILED DESCRIPTION

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] The present application discloses a production equipment for bagged spring string, which is used to realize simultaneous feeding of multiple spring winding machines to increase production, improve the realization rate of ordered merging and conveying of springs, improve production efficiency, and ensure product quality.

[0036] Reference Figures 1-4 A production equipment for bagged spring string includes a spring winding machine 110, a first ring-shaped conveying chain 120, a second ring-shaped conveying chain 130, and a Y-shaped conveying chain 140. The spring winding machine 110 is provided with two machines arranged horizontally side by side. The first ring-shaped conveying chain 120 and the second ring-shaped conveying chain 130 operate synchronously. The first ring-shaped conveying chain 120 and the second ring-shaped conveying chain 130 are respectively used to receive springs 1 from the two spring winding machines 110 and convey the springs 1 to the Y-shaped conveying chain 140. This realizes cooperative work of multiple spring winding machines 110, simultaneous feeding of multiple spring winding machines 110 to increase production, improves the realization rate of ordered merging and conveying of springs 1, improves production efficiency, and ensures product quality.

[0037] Specifically, the first annular conveying chain 120 is provided with a plurality of first magnetic seats 121, and a magnet is arranged in each first magnetic seat 121 to ensure sufficient adsorption force on the spring 1. The first magnetic seat 121 is in the shape of a cuboid and is designed to accommodate a single spring 1. A first inclined groove 122 is formed on the side of the first magnetic seat 121 away from the first annular conveying chain 120, and the first inclined groove 122 penetrates the first magnetic seat 121 along the length direction of the first magnetic seat 121 to improve the accuracy of the spring 1 falling into the first magnetic seat 121. Similarly, the second annular conveying chain 130 is provided with a plurality of second magnetic seats 131, and a magnet is arranged in each second magnetic seat 131 to ensure sufficient adsorption force on the spring 1. The second magnetic seat 131 is in the shape of a cuboid and is designed to accommodate a single spring 1. A second inclined groove 132 is formed on the side of the second magnetic seat 131 away from the second annular conveying chain 130, and the second inclined groove 132 penetrates the second magnetic seat 131 along the length direction of the second magnetic seat 131 to improve the accuracy of the spring 1 falling into the second magnetic seat 131.

[0038] The first magnetic seat 121 and the second magnetic seat 131 are respectively used for adsorbing the spring 1 from the two spring winding machines 110. The plurality of first magnetic seats 121 are uniformly distributed along the transportation direction of the first annular conveying chain 120, and the plurality of second magnetic seats 131 are uniformly distributed along the transportation direction of the second annular conveying chain 130. The first magnetic seat 121 and the second magnetic seat 131 are arranged to ensure that the first annular conveying chain 120 and the second annular conveying chain 130 have sufficient adsorption force on the spring 1, thereby avoiding the spring 1 from falling off during transportation.

[0039] In addition, the springs 1 on one of the spring winding machines 110 are sequentially and intermittently dropped into the plurality of first magnetic seats 121 on the first annular conveying chain 120, and the springs 1 on the other spring winding machine 110 are sequentially and intermittently dropped into the plurality of second magnetic seats 131 on the second annular conveying chain 130. The spring 1 sequentially and intermittently dropped into the first magnetic seat 121 on the first annular conveying chain 120 is also sequentially and intermittently dropped into the second magnetic seat 131 on the second annular conveying chain 130. This design can ensure that the springs 1 on the first conveying chain and the springs 1 on the second conveying chain do not collide when entering the Y-shaped conveying chain 140.

[0040] The matching relationship between the first and second ring-shaped conveying chains 120 and 130 is particularly important. In the present embodiment, the conveying paths of the first and second ring-shaped conveying chains 120 and 130 are parallel to each other and form a staggered layout at the inlet 142 of the Y-shaped conveying chain 140. This not only can adapt to the structure in which the two spring winding machines 110 are horizontally placed side by side, fully utilize the space, and improve the overall compactness of the device, but also can ensure that the springs 1 on the two conveying chains do not collide when entering the Y-shaped conveying chain 140, i.e., from a bottom view, the length of the first ring-shaped conveying chain 120 is longer than that of the second ring-shaped conveying chain 130, the first ring-shaped conveying chain 120 is located on the central axis of the Y-shaped conveying chain 140, and the first ring-shaped conveying chain 120 is closer to the inlet 142 of the Y-shaped conveying chain 140 than the second ring-shaped conveying chain 130. When the springs 1 on the second ring-shaped conveying chain 130 are attracted by the second magnetic seat 131 and come into contact with the Y-shaped conveying chain 140, the springs 1 will be squeezed and have a tendency to move closer to the central axis of the Y-shaped conveying chain 140. This design not only can ensure that the springs 1 remain neatly arranged during merging, but also can effectively prevent the springs 1 from being misaligned.

[0041] The design of the Y-shaped conveying chain 140 is also crucial. The Y-shaped conveying chain 140 has two input ports 141, one of which is located directly below the first ring-shaped conveying chain 120 and corresponds to the output end of the first ring-shaped conveying chain 120, and the other of which is located on one side of the second ring-shaped conveying chain 130 and corresponds to the output end of the second ring-shaped conveying chain 130. This layout enables the springs 1 from the first ring-shaped conveying chain 120 and the springs 1 from the second ring-shaped conveying chain 130 to accurately enter the Y-shaped conveying chain 140, thereby achieving efficient merging.

[0042] To improve the merging efficiency, the inlet 142 of the Y-shaped conveying chain 140 is tapered. When the springs 1 come into contact with the Y-shaped conveying chain 140, they are squeezed and have a tendency to move closer to the central axis of the Y-shaped conveying chain 140. This design can guide the springs 1 to gradually move closer together, thereby achieving a more compact arrangement and improving the efficiency of spring 1 merging.

[0043] To improve the flexibility of the device, a pushing assembly 150 is also included. The pushing assembly 150 is arranged on one side of the second ring-shaped conveying chain 130 and is used to move the springs 1 on the second ring-shaped conveying chain 130 closer to the first ring-shaped conveying chain 120. The pushing assembly 150 is driven by a gas cylinder, which is connected to a push plate through a linkage mechanism. When the gas cylinder is activated, it drives the push plate to move towards the first ring-shaped conveying chain 120, thereby pushing the springs 1 to the appropriate position and improving the efficiency of spring 1 merging.

[0044] The implementation principle of the embodiment 1 of the present application is as follows: after the two spring winding machines 110 wind the spring 1 and cut off, the spring 1 falls onto the first ring-shaped conveying chain 120 and the second ring-shaped conveying chain 130 respectively, the first ring-shaped conveying chain 120 is conveyed clockwise to the Y-shaped conveying chain 140 below, the spring 1 on the first ring-shaped conveying chain 120 directly enters the Y-shaped conveying chain 140, the first ring-shaped conveying chain 120 and the second ring-shaped conveying chain 130 are synchronously operated, the spring 1 on the second ring-shaped conveying chain 130 collides with one side of the Y-shaped conveying chain 140, is slowly squeezed into the second magnetic seat 131 on the first ring-shaped conveying chain 120, and then is slowly pressed into the Y-shaped conveying chain 140, thereby improving the yield of the spring 1, enriching the product types of the spring 1, realizing the simultaneous material falling of multiple spring winding machines 110 to increase the yield, improving the realization rate of the ordered merging and conveying of the spring 1, improving the production efficiency, and ensuring the product quality.
