Abstract
The utility model provides an independent spring package bag for sofas and bed cushions, comprising a plurality of independent spring bags which are mutually connected in a row; one spring is arranged in each independent spring bag; one overlap joint which does not stitch is arranged at the side edge of the each independent spring bag. The utility model removes the disadvantages of the traditional technology which needs secondary stitching and which needs to installation two stitching devices, adopts primarily stitching to firmly package the spring in the package bag, and adopts the overlap joint method of the side edges without stitching; thus, the utility model is beautiful in forming.
Description
Technical field
The utility model relates to a kind of packaging bag, the independent springing packaging bag that particularly a kind of sofa, mattress are used.
Background technology
Existing sofa, the packaging bag of mattress independent springing are will arrange with hot pressing or ultrasonic technology to be seamed into a plurality of bonded assembly independent springing bags side by side mutually, and putting in each independent springing bag simultaneously in the process that sews up has a spring,
As the patent No. is 01271517.4 existing sofa, the packaging bag of introducing of generally using of mattress independent springing, and there is a tape edge side of this packaging bag, and the both sides of each packaging bag still have tape edge, so this packaging bag is osed top all around.The shortcoming of existing similar above-mentioned this packaging bag is the many and equipment complexity of Fabrication procedure, make secondary welding, at first will weld the tape edge of side, makes bagging become a cloth, and then puts into spring and the vertical bag of welding limit.
The utility model content
The purpose of this utility model is to overcome the shortcoming that existing independent springing packaging bag exists, and improves its manner of packing, makes equipment simple, and technological process is few, thereby reaches the effect that reduces production costs.
The purpose of this utility model can realize by following scheme:
The independent springing packaging bag of a kind of sofa, mattress, by a plurality of mutually side by side bonded assembly independent springing bag form, a spring is housed in each independent springing bag, it is characterized in that: the side of each independent springing bag has an overlap joint mouth that does not sew up, and the described search speed that is positioned at the overlap joint mouth of packaging bag side is 2～10cm.
Realize that technological process of the present utility model is:
1. nonwoven fabrics becomes the socket with matching edge of annular by after the selvage guide system;
2. robotic suturing device (ultrasonic welding system) is sewed up an end of socket;
3. draw material mechanism that socket is drawn lattice forward;
4. send spring mechanism that spring is sent in the socket;
5. robotic suturing device is sewed up socket to make once and is formed a spring bag.
Repeat 3,4,5 steps, sew up a plurality of rows' of being linked to be the packaging bag that spring is housed continuously, when advancing cloth, make the socket matching edge place the side of bag to make and form the overlap joint mouth.
Be compared with the prior art, the utility model has following characteristics and progress:
1. conventional art is when becoming nonwoven fabrics into annular socket, need robotic suturing device to sew up, and then carry out shock mount and close with a bag side seam, so the secondary sewing process is arranged, need to install two robotic suturing devices, and the utility model only needs once to sew up, and reaches equally spring firmly is packaged in effect in the packaging bag.
2. the utility model side adopts overlapping mode and need not to sew up, and profile is more attractive in appearance.

The specific embodiment
The independent springing packaging bag of a kind of sofa as depicted in figs. 1 and 2, mattress, by a plurality of mutually side by side bonded assembly independent springing bag 1 form, a spring 2 is housed in each independent springing bag 1, it is characterized in that: the side of each independent springing bag 1 has a bridging type sack 1.1.
Production process of the present utility model is as shown in Figure 3:
1. nonwoven fabrics 5 becomes the socket with matching edge of annular by after the selvage guide system 6;
2. robotic suturing device 7 (ultrasonic welding system) is sewed up an end of socket;
3. draw material mechanism 8 that socket is drawn lattice forward;
4. send spring mechanism that spring 2 is sent in the socket;
5. robotic suturing device 7 is sewed up socket to make once and is formed a spring bag 1.
Repeat 3,4,5 steps, sew up the packaging bag that spring is housed in a row continuously, when advancing cloth, make the socket matching edge place the side of bag to make and form overlap joint mouth 1.1.
Claims (2)
1. sofa, mattress independent springing packaging bag, by a plurality of mutually side by side bonded assembly independent springing bag form, a spring is housed in each independent springing bag, it is characterized in that: the side of each independent springing bag has an overlap joint mouth that does not sew up.
2. a kind of sofa according to claim 1, mattress independent springing packaging bag is characterized in that: the described search speed that is positioned at the overlap joint mouth of packaging bag side is 2～10cm.
