This application is based on and claims the benefit of priority from Chinese Patent Application No. 202311363473.3, filed on 19 Oct. 2023, which are incorporated by reference herein in their entirety.
The present disclosure relates to the field of spring bed mesh production, and in particular, to a spring bed mesh sewing device and a spring bed mesh sewing method.
Independent bagged spring bed mesh is usually manufactured by combining a plurality of rows of spring strings in parallel. Existing bed mesh combination device mainly has two combination modes: glue bonding and ultrasonic welding. The disadvantages of glue bonding lie in large amount of hot melt adhesive, high cost, and non-environmental protection. Ultrasonic welding can improve the environmental protection level for the spring bed mesh, but has the disadvantage that it is only suitable for fusible materials, such as nonwoven fabrics made of polyester or polyester fibers.
In the related art, there is already automated equipment that can produce spring strings made of natural fiber (cotton, wool, silk, linen, etc.) fabrics by sewing. However, the material of this type of fabric cannot be welded using ultrasonic, necessitating the use of adhesive to bond various spring strings. This, in turn, reduces the environmental protection level for the spring bed mesh. Although it is possible to manufacture the bed mesh by manual stitching, this method is characterized by low production efficiency, high production costs, and inconsistent product quality.
The present disclosure aims to solve at least one of the technical problems in the existing technology. To this end, the present disclosure provides a spring bed mesh sewing device and a spring bed mesh sewing method. The spring bed mesh sewing device can sew spring strings into a spring bed mesh.

A spring bed mesh is composed of spring strings in a plurality of rows. Springs are encapsulated in fabric to form a spring string, which includes a plurality of bagged springs connected in sequence. The existing spring bed mesh usually requires the use of hot melt adhesive when assembling, which results in the production process of the spring bed mesh being highly polluting, and the finished products being not environmentally friendly enough, making it difficult to meet the requirements of low-carbon and environmentally friendly production. Although the use of welding technology to combine a spring bed mesh can reduce the use of hot melt adhesive, the range of fabrics suitable for the welding technology is small and the usage scenarios are limited.
In the related art, a device for packaging and manufacturing spring strings using a sewing process has emerged. However, there is still a lack of corresponding automated device in the process of combining spring strings into spring bed mesh.

Referring to
It can be understood that the feeding assembly 100 lays spring strings 900 in various rows in sequence, and the spring strings 900 in various rows can be connected together. At this time, the spring strings 900 fed by the feeding assembly 100 are continuous spring strings 900. The feeding assembly 100 is configured to lay the spring strings 900 in odd rows and even rows respectively during forward and reverse movements in the transverse direction. Alternatively, the spring strings 900 in respective rows can be disconnected before assembly. At this time, the spring strings 900 fed by the feeding assembly 100 are disconnected spring strings 900. The feeding assembly 100 can be configured to not only lay the spring strings 900 in odd rows and even rows respectively during forward and reverse movements in the transverse direction but also lay the spring strings 900 only during the forward movement. Starting from the spring string 900 in the second row, each time the spring string 900 in a row is laid, the cloth pressing assemblies 300 press the sewing positions to be sewn on the bases 220, and the sewing assemblies 200 alternately sew the first sewing positions 910 and the second sewing positions 920.
The present disclosure further provides a spring bed mesh sewing method, including the following steps:
By using the sewing assemblies, the spring bed mesh sewing device provided by the present disclosure eliminates the need to use hot melt adhesive when assembling spring strings 900, helping to manufacture an adhesive-free spring bed mesh made of natural fibers and improve the environmental protection level of the spring bed mesh. The spring bed mesh sewing device realizes the automated production of sewing type spring bed meshes. The sewing assemblies 200 perform sewing after the spring string 900 in one row is laid, which improves the production efficiency of spring bed meshes and improves the product quality of sewing type spring bed meshes.
The spring bed mesh sewing method provided by the present disclosure uses the spring bed mesh sewing device, and therefore has the beneficial effects provided by the spring bed mesh sewing device, which will not be described again here.
The sewn spring strings 900 need to be transported downstream, so that the feeding assembly 100 can lay spring string 900 to be sewn in a new row. In other words, the spring strings 900 are sewn at the sewing stations of the spring bed mesh sewing device. When the sewing is completed, the sewn spring strings 900 need to be sent out of the sewing stations, and the spring string 900 to be sewn is sent to the sewing stations before a new sewing is started. To this end, in some embodiments, the sewing assemblies 200 can move in the longitudinal direction, so as to push the sewn spring strings 900 to move downstream.
The integration of the conveying function on the sewing assemblies 200 helps to simplify the structure of the spring bed mesh sewing device and the spring bed mesh sewing method. Certainly, the spring bed mesh sewing device may also be provided with a special conveying assembly to complete the longitudinal conveying of the sewn spring strings 900. For example, using a conveying belt as the conveying assembly, the feeding assembly 100 lays the spring strings 900 on the conveying belt. After sewing, the conveying belt is started to convey the spring strings 900 downstream. Alternatively, the conveying function may be integrated on the cloth pressing assemblies 300. After the sewing is completed, the cloth pressing assemblies 300 move in the longitudinal direction again to push out the spring strings 900.
During the sewing, the first sewing positions 910 and the second sewing positions 920 are sewn alternately. That is to say, the sewing assemblies 200 participating in sewing only need to correspond to the first sewing positions 910 or the second sewing positions 920 each time the sewing is performed. The spring bed mesh sewing device may have only one group of sewing assemblies 200, which switch to correspond to the first sewing positions 910 or the second sewing positions 920. Alternatively, the spring bed mesh sewing device has two groups of sewing assemblies 200, which correspond to the first sewing positions 910 and the second sewing positions 920, respectively.
Corresponding to the design concept of providing only one group of sewing assemblies 200, the spring bed mesh sewing device may be further designed as follows: the sewing assemblies 200 can move in the transverse direction, so as to correspond to the first sewing positions 910 or the second sewing positions 920, respectively.
In this case, exemplarily, S1000 in the spring bed mesh sewing method that the sewing assemblies 200 move to correspond to the first sewing positions 910 includes that the sewing assemblies 200 move along the transverse direction and switch to correspond to the first sewing positions 910; S600 that the sewing assemblies 200 move to correspond to the second sewing positions 920 includes that the sewing assemblies 200 move along the transverse direction and switch to correspond to the second sewing positions 920.
Further, when the sewing assemblies 200 can move in the longitudinal direction, in S500, before pulled out from the spring strings 900, the sewing assemblies 200 move along the longitudinal direction to push the sewn spring strings 900 away from the sewing stations. In S900, before the sewing assemblies 200 are pulled out from the spring strings 900, the sewing assemblies 200 move along the longitudinal direction to push the sewn spring strings 900 away from the sewing stations. In S200, the sewing assemblies 200 reach the sewing stations along the longitudinal direction, move in the transverse direction to positions corresponding to the first sewing positions 910, and are then inserted between the spring strings 900 along the vertical direction. In S600, the sewing assemblies 200 reach the sewing stations along the longitudinal direction, move along the transverse direction to correspond to the second sewing positions 920, and are then inserted between the spring strings 900 along the vertical direction.
Corresponding to the design concept of providing two groups of sewing assemblies 200, the sewing assemblies 200 do not need to move in the transverse direction, and only need to be re-inserted into new sewing positions after being pulled out.
In this case, the two groups of sewing assemblies 200 can move synchronously, and the corresponding spring bed mesh sewing method is basically the same as the spring bed mesh sewing method when there is only one group of sewing assemblies 200, except that the action of the sewing assemblies 200 moving in the transverse direction is omitted in steps 200 and 600.
However, in the above spring bed mesh sewing method, since the gap between the spring strings 900 is small, the sewing assemblies 200 can easily damage or even scratch the fabric when inserted, resulting in defective products. To this end, the two groups of sewing assemblies 200 can be designed to move alternately. Specifically, the spring bed mesh sewing device is further designed such that the plurality of sewing assemblies 200 are divided into two groups, and the sewing assemblies 200 of the same group are arranged at intervals in the transverse direction. The sewing assemblies 200 of difference groups are interlaced with each other in the transverse direction. The two groups of sewing assemblies 200 correspond to the first sewing positions 910 and the second sewing positions 920, respectively, and can respectively move in the longitudinal direction, so as to alternately move to the side of the spring strings close to the feeding assembly 100 and then return to the sewing positions, thereby avoiding damage to the spring strings when the sewing assemblies 200 are inserted into the sewing positions, and performing the sewing action alternately. The sewing assemblies 200 push the spring strings 900 to move downstream while returning to the sewing positions along the longitudinal direction.
Obviously, in the same group of sewing assemblies 200, the transverse distance between two adjacent bases 220 corresponds to the transverse size of two bagged springs.
In this case, referring to
In this method of alternately pushing the spring strings 900, since the sewing assemblies 200 are first inserted vertically and then move in the longitudinal direction into position, the risk of damage to the packaging bag (that is, the fabric of the spring strings 900) during the sewing process can be reduced.
It can be understood that the spring bed mesh sewing device needs to include first installation assemblies, and the two groups of sewing assemblies 200 are installed on the two first installation assemblies, respectively, so that the sewing assemblies 200 can move alternately with each other. Each first installation assembly includes a first driver and a second driver 717. The first driver is used to drive the respective sewing assembly 200 to move in the vertical direction, so that the sewing assembly 200 can be pulled out from between the spring strings 900. The second driver 717 is used to drive the respective sewing assembly 200 to move in the longitudinal direction, so as to approach the spring strings 900 laid by the feeding assembly 100 in the longitudinal direction, and push the spring strings 900 into position.
Exemplarily, referring to
Exemplarily, referring to
The first driver may be directly connected to the first installation base 711, or may be indirectly connected to the first installation base 711 through belt drive, chain drive, screw drive, linkage drive, etc. Similarly, the second driver 717 may be directly connected to the second installation base 712, or may be indirectly connected to the second installation base 712 through belt drive, chain drive, screw drive, linkage drive, etc. In addition to the guide rail and guide post, the first guide member 713 and the second guide member 714 may also be designed with reference to existing related art, which will not be described again here.
In some embodiments, the spacing between adjacent sewing assemblies 200 is adjustable, so as to match the spring strings 900 of different specifications. Exemplarily, continuing to refer to
Each first installation assembly may further include a fixing base 716 formed with a fastening groove extending in the transverse direction. The sewing assemblies 200 are fixedly connected to the fastening grooves through fasteners, thereby locking positions after the transverse adjustment. The fixing bases 716 may use standard profiles as shown in
The sewing principle of the sewing heads 210 may refer to sewing machines in the related art. Simply speaking, referring to
Each sewing assembly 200 needs to include a third driver 230, which is used to drive the respective sewing head 210 to move in the vertical direction. The third driver 230 may be directly connected to the sewing head 210, or may also be indirectly connected to the sewing head 210 through belt drive, chain drive, screw drive, linkage drive, etc. For example, referring to
During the vertical sewing process of the sewing heads 210, the cloth pressing assemblies 300 need to continuously and stably cooperate with the bases 220 to press the sewing positions of the spring strings 900, so as to ensure the quality of the sutures. For this reason, the cloth pressing assemblies 300 need to avoid the moving sewing heads 210.
Exemplarily, referring to
Referring further to
The cloth pressing assemblies 300 are located on the same side of the sewing assemblies 200 as the feeding assembly 100 in the longitudinal direction. Therefore, when the feeding assembly 100 lays the spring strings 900, the cloth pressing assemblies 300 need to perform an avoidance movement to avoid the movement path of the feeding assembly 100. The cloth pressing assemblies 300 can perform avoidance in a moving or rotating way. For example, the cloth pressing assemblies 300 are designed to be able to move in the vertical direction, or the cloth pressing assemblies 300 are designed to be able to rotate around the axis in the transverse direction, etc.
In some embodiments, considering that the cloth pressing assemblies 300 may interfere with the sewing assemblies 200 during vertical avoidance (refer to
When the spacing between adjacent sewing assemblies 200 in the transverse direction is adjustable, the spacing between adjacent cloth pressing assemblies 300 also needs to be adjustable, so that the sewing assemblies 200 can be adapted to spring strings 900 of different specifications. Exemplarily, referring to
The feeding assembly 100 conveys the spring strings 900 through the conveying member 110. Exemplarily, referring to
The feeding assembly 100 is further formed with a conveying channel, and the conveying member 110 is located at an outlet of the conveying channel. The conveying channel limits the feeding path of the spring strings 900 to avoid interference between the spring strings 900 and other structures of the spring bed mesh sewing device. For example, in
Since there is a time difference between the feeding assembly 100 laying the spring strings 900, and the cloth pressing assemblies 300 pressing the spring strings 900 and the sewing assemblies 200 sewing the spring strings 900, it is necessary to limit the laid spring strings 900 in advance to prevent that the positions of the spring strings 900 change or even the spring strings 900 fall under their own weights.
To this end, in some embodiments, the spring bed mesh sewing device includes two limit assemblies 400 arranged at an interval in the vertical direction, so as to form a material receiving channel for limiting the spring strings 900. The bases 220 extend in the vertical direction and across the material receiving channel, and the feeding assembly 100 lays the spring strings 900 to the bases 220 located in the material receiving channel. Referring to
The size of the material receiving channel needs to correspond to the size of the spring strings 900. In order to match the spring strings 900 of different specifications, the spacing between the two limit assemblies 400 in the vertical direction can be adjusted. Specifically, one limit assembly 400 may be stationary in the vertical direction, and the other limit assembly 400 may be movable in the vertical direction, or both limit assemblies 400 may be movable in the vertical direction. Exemplarily, referring to
The limit assemblies 400 need to avoid the movement paths of the sewing assemblies 200. Therefore, each of the limit assemblies 400 includes limit bars 410. The limit bars 410 of the same group are arranged at intervals in the transverse direction, and the limit bars 410 are staggered from the sewing assemblies 200 in the transverse direction, so as to allow the sewing assemblies 200 to pass between the limit bars 410. As shown in
Referring to
In some embodiments, the spring bed mesh sewing device further includes a receiving assembly, which is located on the side of the limit assemblies 400 away from the feeding assembly 100. The receiving assembly is docked with the limit assemblies 400 to receive the spring bed mesh formed after sewing. Exemplarily, referring to
The spring string 900 may be provided to the spring bed mesh sewing device in a continuous state, thereby eliminating the step of cutting the spring string 900 to a designed length in advance. In this case, after the feeding of the feeding assembly 100 is completed, the spring bed mesh sewing device needs to cut the continuous spring string 900. To this end, the spring bed mesh sewing device includes a cutting assembly 600 for cutting the spring string 900.
Exemplarily, referring to
Further, referring to
It can be understood that when the spring strings 900 in the rows of the spring bed mesh are separated from each other, the feeding assembly 100 lays the spring string 900 in each row and the cutting assembly 600 performs cutting once. When the spring strings 900 in various rows in the spring bed mesh are connected to each other, the cutting assembly 600 only cuts the spring string 900 in the last row when the spring bed mesh is sewn, so that the completed spring bed mesh is separated from the remaining spring strings 900.
