Description

Technical Field

[0001] The utility model relates to the technical field of sofa manufacturing equipment, in particular to a blanking control mechanism for sofa springs. Background Art

[0002] With the continuous progress of society and the continuous improvement of people's living standards, people's requirements for the comfort of furniture are also getting higher and higher. As a multi-functional sofa, the functional sofa is very popular among people because of its multiple functions, wide application range, fashionable appearance and other advantages.

[0003] Most traditional sofas are directly filled with sponge materials. The production cost of sponge filling is relatively high, and the sponge needs to be made into a corresponding shape during the production process, which is time-consuming and laborious. Moreover, when using sponge filling, the sponge will deform and cannot return to its original shape after a long time of use, resulting in a short service life of the sofa. For example, the patent with the publication number CN205144079U and the patent name of a spring and its sofa cushion discloses a spring and its sofa cushion. The spring includes a spring main body part and a connecting part for connecting and fixing with the sofa bottom plate. The spring main body part is formed by continuously bending a steel wire in an S shape into a strip shape. The two ends of the spring main body part are bent downward respectively to form buffer parts, and the buffer parts are connected with the connecting part. The utility model can solve the problem that the spring in the traditional technology is easy to break due to stress, effectively extend the service life of the product, and save the usage amount of sponge.

[0004] In order to install this serpentine spring, a storage mechanism is used for supplying the spring. When the springs are stacked relatively high in the storage structure, due to the weight of the springs themselves, the springs at the bottom end are deformed, and the ends of the two springs are simultaneously abutted against the material blocking seat, resulting in multiple springs being discharged at the same time. When there are too few springs, due to their own elastic force, the two ends of the spring are far away from the material blocking seat, resulting in unsmooth discharging and reducing the production efficiency. Summary of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the utility model provides a blanking control mechanism for sofa springs, which can control the blanking of sofa springs, effectively ensure smooth blanking, and improve production efficiency.

[0026] See Figure 4 , the spring 2 is a strip-shaped structure formed by continuously bending a steel wire in an S shape. The end of the spring 2 is bent to form two first arc-shaped portions 21, and between the two first arc-shaped portions 21 are composed of several continuously arranged intermediate arc-shaped portions.

[0027] See Figures 1 to 3 , a blanking control mechanism for a sofa spring, is arranged on the frame 4 and is used in cooperation with the automatic installation mechanism of the sofa spring.

[0028] The specific structure includes a material storage mechanism 1 and a blanking control mechanism 3 that is arranged to match the material storage mechanism 1. The material storage mechanism 1 includes a limit post assembly composed of a limit post fixing plate 10 and limit posts 11 fixed on the limit post fixing plate 10.

[0029] An installation position is provided on the limit post fixing plate 10. The limit posts 11 are arranged on the limit post fixing plate 10 in the vertical direction through the installation position, and the position can be adjusted through the installation position. Obviously, in cooperation with the spring structure, preferably two limit posts 11 are provided, which is beneficial for a number of springs 2 to be neatly stacked together.

[0030] Blanking seats 12 are symmetrically arranged on both sides of the limit post assembly respectively. The blanking seat 12 includes a vertically connected vertical portion 121 and a horizontal portion 122. In this way, the two ends of the spring 2 are placed on the horizontal portion 122. Coherent hollow notches are provided on the horizontal portion and the vertical portion, and the notch height of the vertical portion matches the diameter of the spring wire. In this way, every time the pushing part moves, only the bottommost spring can be pushed.

[0031] A limit baffle 13 is connected to the blanking seat 12 and arranged parallel to the limit post fixing plate 10. In this way, the blanking seat 12, the limit post fixing plate 10 and the limit baffle 13 form a storage cavity for storing the spring 2. Of course, the width of this cavity matches the width of the spring. In this way, it can further ensure that the springs can be neatly stacked.

[0032] In order to ensure that as many springs 2 as possible can be stacked, and at the same time ensure that the springs will not be squeezed and deformed due to too many stacked springs, or the blanking will not be smooth due to too few springs. Therefore, a blanking control mechanism 3 is provided corresponding to the position of the storage cavity, which can extend into the storage cavity and keep the springs to be blanked at a fixed number all the time. The blanking control mechanism 3 is electrically connected to the main control system of the equipment. The main control system of the equipment can send control signals to the blanking control mechanism 3 according to the working state, so that after each spring material is sent out, the blanking control mechanism 3 can automatically supplement a spring material to the position to be blanked. Obviously, the installation position of the blanking control mechanism 3 is at least higher than the plane where the horizontal portion 122 of the blanking seat is located.

[0033] The blanking control mechanism 3 includes a driving seat 31, a driving mechanism 32 and a blanking limit assembly. The driving seat 31 is arranged on the frame 4. Of course, the driving seat can also be set as a structure with adjustable height, which is beneficial for adjusting the number of springs to be blanked at any time to match the spring storage under different working conditions and different sizes; the driving mechanism 32 is arranged on the driving seat 31, and the blanking limit assembly is connected to the working end of the driving mechanism 32.

[0034] The blanking limit component includes a first limit baffle 331 and a second limit baffle 332 which are respectively arranged up and down along the height direction of the stacked springs. That is to say, two sets of driving mechanisms 32 are also provided corresponding to the first limit baffle 331 and the second limit baffle 332. One set drives the first limit baffle 331 to act, and the other set drives the second limit baffle 332 to act.

[0035] A first working inclined surface 331a is provided on the front working surface of the first limit baffle 331, and a second working inclined surface 332a is provided on the front working surface of the second limit baffle 332. And the inclination directions of the first working inclined surface 331a and the second working inclined surface 332a are mirror - image settings. And the first limit baffle 331 and the second limit baffle 332 are arranged in parallel, and a gap is provided between the first limit baffle 331 and the second limit baffle 332. The size of the gap provided between the first limit baffle 331 and the second limit baffle 332 matches the wire diameter of the spring 2.

[0036] The specific working principle is as follows: When the blanking control mechanism 3 works, the driving mechanism 32 simultaneously drives the first limit baffle 331 and the second limit baffle 332 to be inserted into the stacked springs. The first working inclined surface 331a and the second working inclined surface 332a are beneficial for the first limit baffle 331 and the second limit baffle 332 to be quickly inserted, and there is a spring 2 between the first limit baffle 331 and the second limit baffle 332. At this time, the upper working surface of the first limit baffle 331 has a certain supporting force on the stacked spring 2 above it, and separates the stacked springs into the reserve spring supported by the upper working surface of the first limit baffle 331, the pre - blanking spring 2 between the first limit baffle 331 and the second limit baffle 332, and the to - be - blanked spring on the lower working surface of the second limit baffle 332. In this way, because the upper working surface of the first limit baffle 331 has a certain supporting force on the stacked spring 2 above it, the extrusion deformation caused by too many stacked springs is reduced, and at the same time, it can ensure that the to - be - blanked springs always maintain a certain number, avoiding the unsmooth discharge caused by too few springs.

[0037] When one spring to be blanked is reduced, the second limit baffle 332 retracts under the drive of the drive mechanism 32, so that the pre-blanking spring 2 between the first limit baffle 331 and the second limit baffle 332 enters the area of the spring to be blanked. Then, the second limit baffle 332 extends under the drive of the drive mechanism 32. Subsequently, the first limit baffle 331 retracts under the drive of the drive mechanism 32, so that the reserve spring supported by the upper working surface of the first limit baffle 331 is supported by the second limit baffle 332. Then, the first limit baffle 331 extends under the drive of the drive mechanism 32, keeping one spring 2 between the first limit baffle 331 and the second limit baffle 332. By repeating such actions, it is possible to always keep a certain number of springs to be blanked, and avoid the problems of extrusion deformation caused by excessive stacking of springs and poor material discharge caused by too few spring numbers.

[0038] The above technical solution is beneficial to improving production efficiency and market competitiveness.

The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and described in the embodiments.
