Example

[0035] See also Figure 1-7The present invention discloses an automatic hanging mechanism for sofa springs, which comprises a frame 1 that can be placed and fixed on the ground, a group of slide rails 2 fixed above the frame 1, a feeding mechanism 3 that can be slidably arranged on the group of slide rails 2, a support frame 7 fixedly arranged on the frame 1 and outside the group of slide rails 2, a storage mechanism 4 fixed in the support frame 7 from top to bottom, a discharge mechanism 5 for blocking and releasing the sofa springs in the storage mechanism 4, and a pressing mechanism 6 for pressing the falling sofa springs into the discharge position, wherein the above-mentioned discharge position is composed of two symmetrical hooking components 31 and a discharge table 512, and multiple such discharge positions can be configured according to actual conditions; through the coordinated action of the storage mechanism, the discharge mechanism and the pressing structure mechanism, the automatic hanging of the sofa springs is realized.

[0036] See also Figure 1-7 The present invention provides an automatic hanging method for sofa springs, comprising the following steps: Step 1: Loading: Place the sofa spring with a serpentine structure in the storage mechanism 4 and limit it through the limiting column 42, so that the sofa spring is supported at the discharge mechanism 5, during which a plurality of sofa springs can be stacked into the storage bin 41; Step 2, unloading: the unloading mechanism 5 releases the bottom sofa spring in the storage mechanism 4 and abuts against the previous one to the unloading seat 51, so that the two sections of the sofa spring are respectively abutted against the two oblique protrusions 513. Specifically, the unloading mechanism 5 can complete the function of abutting against one sofa spring and releasing one sofa spring at the same time, so that it works in an orderly manner; Step 3, pressing: the plurality of sofa springs supported on the two oblique protrusions 513 are pressed into the two symmetrical hooking components 31 in the feeding and receiving mechanism 3 by the pressing mechanism 6. The plurality of sofa springs can be pressed into the two hooking components 31 of the feeding and receiving mechanism 3 in sequence, wherein the number of the two symmetrical hooking components 31 is determined according to actual needs; Step 4, material transfer: The feeding mechanism 3 with the sofa spring is moved to the sofa spring installation position through the two slide rails 2 through the screw cylinder combination 33.

[0037] See also Figure 1The above-mentioned storage mechanism 4 penetrates the support platform 70 of the support frame 7 from top to bottom. The support platform 70 adopts a frame-type structure design and is hollow in the middle, which is convenient for the installation and smooth operation of the storage mechanism 4. At the same time, the storage mechanism 4 is located directly above the discharge seat 51 to ensure that the sofa springs in the storage mechanism 4 can accurately fall to the discharge position; in this embodiment, the storage mechanism 4 is composed of a storage bin 41 and a vertical limit column 42 fixedly arranged inside the storage bin 41. The limiting column 42 can pass through the bending part of the sofa spring, so as to limit the sofa spring, ensure that it is neatly arranged in the storage bin 41, and ensure that the unloading position is accurate; a plurality of sofa springs arranged in an orderly manner are stored in the storage bin 41, and these sofa springs are blocked and released by the discharge mechanism 5. Since the sofa springs need to be pressed into the feeding mechanism 3 in sequence through the pressing mechanism 6, in the actual operation process, the discharge mechanism 5 will release the bottom sofa spring while blocking the previous sofa spring, so as to prepare for the next release. In short, the discharge mechanism 5 has both blocking and releasing functions. The function of releasing the sofa spring ensures that the whole process is efficient and orderly; through reasonable structural layout and function allocation, efficient storage, precise positioning and orderly release of the sofa spring are realized. Specifically, the storage efficiency is improved: the cooperation between the storage bin 41 and the limit column 42 ensures the stability and orderliness of the sofa spring during the storage process; the unloading accuracy is enhanced: the design of the limit column 42 effectively avoids the deviation or jamming of the sofa spring during the unloading process; the operation process is optimized: the blocking and releasing functions of the unloading mechanism 5 are combined to ensure that the sofa springs can be transferred to the subsequent processes one by one in the established order, thereby improving the overall production efficiency.

[0038] See also Figure 1-7 The above-mentioned support frame 7 includes a hollow support platform 70, which is mainly used to fix the discharge mechanism 5. The hollow support platform 70 is installed on the frame 1 through support columns 71 at both ends, and the support columns 71 are arranged on the outside of the two slide rails 2. Such a layout not only ensures the overall stability of the support frame 7, but also provides sufficient space for the smooth operation and passage of the feeding mechanism 3 on the frame 1; the combined design of the hollow support platform 70 and the support column 71 effectively enhances the bearing capacity and stability of the support frame 7, while reducing the overall weight. The design of the support column 71 located on the outside of the slide rail 2 avoids interference with the operation of the docking feeding mechanism 3, ensuring that it can complete the operation efficiently and smoothly. The design of the hollow support platform 70 not only improves the material utilization rate, but also provides more flexibility for the arrangement of other components inside the equipment.

[0039] See also Figure 1-7The above-mentioned discharge mechanism 5 includes a discharge cylinder connecting plate 52 fixed on the support platform 70, on which a discharge cylinder 54 and a stopper cylinder 53 are sequentially installed from bottom to top, wherein the output ends of the discharge cylinder 54 and the stopper cylinder 53 are respectively provided with a discharge block 541 and a stopper block 531. In this embodiment, the discharge cylinder 54 releases the blocked sofa spring to a designated placement position through the discharge block 541, so that the pressing mechanism 6 can perform the pressing operation; at the same time, the stopper cylinder 53 releases the next sofa spring through the stopper block 531. The spring is blocked and released into the discharge block 541 at an appropriate time, thereby completing a complete discharge process. The sofa spring is released onto the discharge seat 51 by the discharge block 541 controlled by the discharge cylinder 54. Specifically, the discharge seat 51 includes a discharge table 512, which is docked with the two hook components 31 of the feeding mechanism 3. The discharge table 512 is fixed to the frame 1 through the fixed columns 511 on both sides below. In addition, two oblique protrusions 513 symmetrical with the center of the discharge table 512 are respectively arranged at the upper and lower ends of the discharge table 512. When the sofa spring is released to the discharge table 512, during the process of the pressing mechanism 6 performing the pressing action, the sofa spring can be quickly and accurately pressed into the hooking assembly 31 on both sides of the discharge table 512 by means of the impact force generated by the two oblique protrusions 513; the above scheme not only realizes the accurate discharge and pressing of the sofa spring, but also takes into account the compact structure and convenient operation, functional synergy: the discharge cylinder 54 and the blocking cylinder 53 have clear division of labor, and can efficiently cooperate to complete the blocking and release of the sofa spring, ensuring the continuity and stability of the discharge process; structural rationality: the design of the discharge seat 51 is ingenious, and the discharge table 512 is firmly installed on the frame 1 through the fixed column 511, ensuring the stability of the overall structure; operational efficiency: the oblique protrusions 513 on the discharge table 512 are uniquely designed, and when the pressing mechanism 6 is working, the sofa spring can be quickly and accurately pressed into the hooking assembly 31 by means of the impact force, which significantly improves the work efficiency.

[0040] See also Figure 1-7After the above-mentioned discharge mechanism 5 releases a sofa spring to the discharge table 512, the pressing mechanism 6 is responsible for accurately pressing it into the two hooking components 31; specifically, the pressing mechanism 6 mainly includes a pressing cylinder 61 fixed on the table of the frame 1, a pressing cylinder connecting plate 62 installed at the output end of the pressing cylinder 61, and a pressing telescopic cylinder 63 configured on the pressing cylinder connecting plate 62, and the output end of the above-mentioned pressing telescopic cylinder 63 is provided with a pressing plate 64; in the working process, after the discharge mechanism 5 completes the release of the sofa spring, the pressing telescopic cylinder 63 drives the pressing plate 64 to move to just above the sofa spring; then, the pressing cylinder 61 is started, driving the pressing cylinder connecting plate 62 and the pressing telescopic cylinder 63 to move downward as a whole, so that the pressing plate 64 contacts the sofa spring and applies sufficient pressure to accurately press the sofa spring into the two hooking components 31, completing a pressing operation; according to actual production needs, The position of the feeding and receiving mechanism 3 is adjusted so that the second sofa spring is pressed into another pair of hooking components 31 by the pressing mechanism 6 in the same way; and so on, continuous and efficient automated operation is achieved; this solution not only realizes the automation of the entire process from feeding to pressing of the sofa spring, but also fully considers the flexibility and reliability in actual production; the structure is reasonable: the pressing mechanism 6 is composed of a pressing cylinder 61, a pressing cylinder connecting plate 62, a pressing telescopic cylinder 63 and a pressing plate 64, and each component has a clear function and is tightly matched, ensuring the efficiency and stability of the operation; accurate positioning: the pressing plate 64 is accurately moved to the top of the sofa spring by the pressing telescopic cylinder 63, and combined with the vertical driving force provided by the pressing cylinder 61, it can effectively avoid deviation or damage during the pressing process; strong adaptability: by adjusting the position of the docking feeding mechanism 3, it can flexibly cope with the hooking components 31 in different positions to meet the production needs of multiple stations or multiple batches.

[0041] See also Figure 1-7The feeding and receiving mechanism 3 has the function of taking out the sofa spring from the storage mechanism 4 and fixing and transferring it. Specifically, two groups of symmetrically arranged hooking components 31 on the feeding and receiving mechanism 3 are used to complete the placement and fixing of the sofa spring. These symmetrically distributed hooking components 31 can be designed as multiple groups, so as to achieve the effect of fixing multiple sofa springs at the same time. The transfer function of the material receiving and feeding mechanism 3 is realized by the screw cylinder combination 33, which can transfer the material receiving and feeding mechanism 3 with the hook assembly 31 from one side (the right side, for preparing to place and fix the sofa springs) of the storage mechanism 4 to the other side (the left side, for cooperating with the external mechanism to fix the sofa springs to the sofa frame); in terms of specific structure, the material receiving and feeding mechanism 3 includes the following components: a group of sliding rods 30 with sliders, which can slide in the slide rail 2; the hook assembly 31 fixed on the sliding rod 30 and evenly distributed; the transversely fixed fixed rod 32, which is used to connect and stabilize a group of sliding rods 30; the screw cylinder combination 33, which is used to drive the material receiving and feeding mechanism 3 to move horizontally along the slide rail 2; wherein, the movable end of the screw cylinder combination 33 is connected to the fixed rod 32, and its fixed end is installed at a position close to the storage mechanism 4. In addition, the two symmetrically arranged hooking components 31 and the material discharging platform 512 jointly form a material discharging position; further, the specific structure of the hooking component 31 is as follows: the hooking connecting seat 311 is fixed on the sliding rod 30; the hooking seat 310 is fixed on the hooking connecting seat 311, and a group of guide members 315 are arranged toward the material discharging platform 512; a sofa spring placement groove 312 is designed at the matching position between the guide member 315 and the hooking seat 310; a hook block 313 is arranged in the sofa spring placement groove 312, and the hook block 313 is arranged with an arc groove 314 facing the center of the hooking seat 310 for facilitating the mutual cooperation with the sofa spring; it should be noted that The sofa spring placement slot 312 corresponds to the discharge platform 512 to ensure that the sofa spring can be accurately placed in place; high efficiency: through multiple groups of symmetrically arranged hook components 31, the function of fixing multiple sofa springs at the same time is realized, which greatly improves the production efficiency; flexibility: the feeding mechanism 3 can achieve horizontal movement through the screw cylinder combination 33, and the position can be flexibly adjusted to meet the needs of different workstations; accuracy: the sofa spring placement slot 312 in the hook component 31 corresponds precisely to the discharge platform 512, combined with the design of the guide 315 and the hook block 313, to ensure the accurate placement and fixation of the sofa spring.

[0042] The present invention significantly improves the accuracy and efficiency of sofa spring hanging through innovations such as symmetrical slide rail layout, integrated material storage and release, and crimping positioning, while reducing dependence on vibration feeding or manual intervention. It is particularly suitable for large-scale automated production needs in the furniture manufacturing field.
