Description

Technical Field

[0001] The invention relates to the technical field of spring sofas, and in particular to a method for compressing an entire sofa and a compression device thereof. Background Art

[0002] Spring sofas are generally formed by stacking two armrests made of pocket springs and / or soft materials on top of the spring cushions, and a backrest made of pocket springs is arranged behind or above the spring cushions. In order to transport the spring sofa, it is generally necessary to compress and pack the spring sofa before transportation. At this time, a compression device is needed.

[0003] The existing compression of spring sofas generally involves separating the backrest and / or armrests of the spring sofa from the base and then compressing and packing them separately. However, for an integral sofa, the entire sofa needs to be compressed during compression. Although the existing compression equipment can also directly compress the entire sofa at one time, the armrests and / or backrest of the sofa are easily turned outward during the compression process, resulting in the armrests and / or backrest being separated from the base and damaged. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a method and a device for compressing an entire sofa.

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to facilitate a clearer understanding of the technical ideas claimed for protection in the present invention.

[0032] A sofa overall compression method comprises the following steps:

[0033] S1: The sofa is placed in the designated position of the support platform and waits for compression;

[0034] S2: Before the compression plate contacts the sofa, the limiting member extends to limit the armrest and / or backrest of the sofa;

[0035] S3: The compression plate moves to contact with the sofa and compresses the sofa, while the limiter is extended and retracted synchronously with the compression plate;

[0036] S4: The compression plate continues to move until the compression action on the sofa is completed;

[0037] S5: The limiter is reset or the position of the limiter is fixed, the compression plate is reset, and the next sofa is waiting for input.

[0038] It should be noted that the resetting of the limiting member described in the present invention specifically refers to: the limiting member is displaced to the initial position relative to the compression plate or the supporting platform (specifically, the position when the limiting member is not displaced and extended when the sofa is input into the supporting platform).

[0039] It should be noted that the compression plate resetting of the present invention specifically means that the compression plate moves to a position where the sofa is waiting to be input into the supporting platform.

[0040] The advantages of the present invention are as follows: 1. Before the sofa is compressed, the armrests and / or backrest of the sofa are limited by the limiting member, which effectively prevents the armrests and / or backrest of the sofa from being forced to tilt outward during compression, causing the armrests and / or backrest to separate from the sofa and produce waste.

[0041] Furthermore, before the compression plate contacts the sofa, the limiting member extends to limit the armrest and / or backrest of the sofa. Specifically, the limiting member extends to limit the armrest and / or backrest of the sofa before the compression plate is displaced; or the limiting member is synchronously extended to limit the armrest and / or backrest of the sofa during the process of the compression plate being displaced to contact the sofa; or the limiting member is extended to limit the armrest and / or backrest of the sofa when the compression plate is displaced to a position where it is about to contact the sofa.

[0042] Further, the compression plate is reset, the limiter is reset or the limiter is fixed, and waiting for the input of the next sofa specifically includes: the compression plate is reset, the limiter is reset, and waiting for the input of the next sofa; or the compression plate is reset, the limiter is fixed, and waiting for the input of the next sofa.

[0043] like Figures 2-3 The figure shows a specific device for realizing the method of resetting the compression plate, fixing the position of the limiter, and waiting for the input of the next sofa. In the device, the limiter 3 is fixed by a fixing mechanism 4 using an electric finger.

[0044] like Figures 4-5 The figure shows a specific device for realizing the compression plate reset and the position limiting member reset of the method and waiting for the input of the next sofa. In the device, the position limiting member 3 is driven to reset by a fixing mechanism 4 using a cylinder.

[0045] A sofa integral compression device, used for implementing the steps of a sofa integral compression method as claimed in any one of claims 1 to 4, the device comprising: a supporting platform 1, a compression plate 2 and a limiting member 3;

[0046] A supporting platform 1, used for supporting the sofa;

[0047] A compression plate 2 is used to compress the sofa on the supporting platform;

[0048] The limiting member 3 can extend from the supporting platform 1 or the compression plate 2, and the limiting member 3 is used to limit the armrest and / or backrest of the sofa when the compression plate 2 compresses the sofa.

[0049] More specifically, when the present invention is in use, the sofa is input as a whole to the designated position of the supporting platform 1, the limiting member 3 is extended so that the limiting member 3 limits the armrest and / or backrest of the sofa, and then the compression plate 2 is displaced to compress the sofa. During the displacement of the compression plate 2, the armrest and / or backrest of the sofa are limited by the limiting member 3 so that they will not deviate outwards, the compression plate 2 continues to displace, and the limiting member 3 is synchronously contracted until the compression plate 2 completes the compression of the sofa, and then the position of the limiting member 3 is fixed or contracted and reset, waiting for the input of the next sofa.

[0050] It should be noted that the extension and limiting action of the limiting member 3 and the displacement action of the compression plate 2 can be performed simultaneously, as long as the extended position of the limiting member 3 can limit the sofa before the compression plate 2 presses onto the sofa or when the compression plate 2 just presses onto the sofa.

[0051] The advantage of the present invention is that by setting the limiting member, the armrest and / or backrest of the sofa are limited by the limiting member before the compression plate compresses the sofa, effectively preventing the armrest and / or backrest of the sofa from deviating outward when the sofa is compressed as a whole.

[0052] Furthermore, a conveyor belt 11 is provided on the supporting platform 1 .

[0053] More specifically, by providing a conveyor belt 11, the supporting platform 1 can convey or output the sofa, which is beneficial to the positioning of the sofa and the output of the finished product.

[0054] Furthermore, the limiting member 3 is a limiting rod or a limiting plate.

[0055] More specifically, by limiting the outer sides of the armrests and / or backrest of the sofa through the limiting rods or limiting plates, the armrests and / or backrest can be effectively prevented from deflecting outwards when under pressure.

[0056] Furthermore, corresponding to the positions on the outer sides of the armrests and / or backrest of the sofa, at least one limiting member 3 is provided at each position.

[0057] More specifically, the limiting member 3 corresponds to the armrest and / or backrest at least one to one, which can ensure that the armrest and backrest of the sofa can be limited by the limiting member 3, effectively preventing the armrest and backrest from deviating outward.

[0058] Furthermore, it also includes a driving mechanism 5, and the driving mechanism 5 is used to drive the compression plate 2 to rise and fall.

[0059] More specifically, the driving mechanism 5 is a hydraulic cylinder, which drives the compression plate 2 to rise and fall and provides sufficient pressure to compress the sofa.

[0060] Furthermore, it also includes a balancing mechanism 6, and the balancing mechanism 6 is used to keep the compression plate 2 lifted and lowered horizontally.

[0061] More specifically, the balancing mechanism 6 includes a balancing rod 61, a rack 62 and a gear 63. The balancing rod 61 is installed on the compression plate 2. Gears 63 are provided at both ends of the balancing rod 61. A plurality of racks 62 are provided on the support platform 1. The gears 63 and the racks 62 are meshed. A plurality of balancing rods 61 are provided on the compression plate 2, so that the compression plate 2 can maintain horizontal lifting.

[0062] Furthermore, it also includes a fixing mechanism 4, and the fixing mechanism 4 is used to fix the position of the limiting member 3.

[0063] Furthermore, the limiting member 3 is slidably connected to the compression plate 2 , and the fixing mechanism 4 is at least used to fix the position of the limiting member 3 .

[0064] In one embodiment of the present invention, in this embodiment, the position-limiting member 3 is installed on the compression plate 2 , and the fixing mechanism 4 at least has the function of fixing the position-limiting member 3 .

[0065] like Figures 2-3 The figure shows one of the specific embodiments of the embodiment. In this embodiment, the limit member 3 is a limit rod, and the fixing mechanism 4 is an electric finger. The specific use process is to input the sofa as a whole to the specified position of the supporting platform 1, and the fixing mechanism 4 releases the limit member 3 so that the limit member 3 extends downward to limit the armrest and / or backrest of the sofa, and then the compression plate 2 moves to compress the sofa. During the displacement of the compression plate 2, the armrest and / or backrest of the sofa will not deviate outward due to the limitation of the limit member 3, and the compression plate 2 continues to move, and the limit member 3 shrinks synchronously until the compression plate 2 completes the compression of the sofa, and then the fixing mechanism 4 clamps and fixes the position of the limit member 3, waiting for the input of the next sofa.

[0066] Furthermore, the limiting member 3 is slidably connected to the supporting platform 1 , and the fixing mechanism 4 is used to drive the limiting member 3 to slide, retract and fix its position on the supporting platform 1 .

[0067] In one embodiment of the present invention, in this embodiment, the position-limiting member 3 is installed on the supporting platform 1, and the fixing mechanism 4 can drive the position-limiting member 3 to telescopically move and fix it at a specified position.

[0068] like Figures 4-5The figure shows one of the specific embodiments of the embodiment. In this embodiment, the limiting member 3 is a limiting rod, and the fixing mechanism 4 is a cylinder. The specific use process is to input the sofa as a whole to the specified position of the supporting platform 1, and the fixing mechanism 4 drives the limiting member 3 so that the limiting member 3 extends to limit the armrest and / or backrest of the sofa (specifically, the piston rod of the cylinder moves to make the limiting member 3 extend relative to the supporting platform 1), and then the compression plate 2 moves to compress the sofa. During the displacement of the compression plate 2, the armrest and / or backrest of the sofa will not deviate outward due to the limitation of the limiting member 3, and the compression plate 2 continues to move. At the same time, the fixing mechanism 4 drives the limiting member 3 to shrink synchronously until the compression plate 2 completes the compression of the sofa, and then the fixing mechanism 4 fixes the position of the limiting member 3 (specifically, after the piston rod of the cylinder is extended and retracted, the limiting member 3 is fixed to the original position below the supporting surface of the supporting platform 1), waiting for the input of the next sofa.
