Abstract
The present invention discloses a device for encapsulating spring components (38-40), which comprises a device (13) for making one spring component inserted in a pair of fabrics (16), devices (26) for tightening or tensioning the fabrics at the periphery of the spring component, and a fastening device for fastening the two fabrics which are tightly packaged and clung to the compressed spring components so as to encapsulate the spring components. Simultaneously, the present invention also discloses a method for encapsulating the spring components.
Description
The present invention relates to be used in the spring assembling of mattress or other upholster spare and the equipment and the method for encapsulation.
" spring installation " speech meaning herein is that many wind springs are arranged with gauze one after another three-dimensionally and connected together.Wind spring be connected gauze and can make respectively, couple together by one section or several sections gauzes then.
" fabric " speech is meant as the cloth fabric at this, fabric, and laminated material or any other are used for doing or can being used for doing the material of mattress and other upholster spare.
The object of the present invention is to provide a kind of actv., the method for economically viable equipment and confession mattress or the assembling of other upholster spare spring assembly.
According to a further aspect in the invention, for in the middle of pair of fabric, providing equipment as mentioned below as above-mentioned encapsulation spring assembly, this equipment is included in the middle insertion device that inserts spring installation of pair of fabric, the device of using at spring installation tighten around or tensioning fabric, the compression set of compression spring spare and be close to compression spring spare fastening fabric is so that the tightening device of encapsulation spring installation.
Tightening device is director's arm sewing machine preferably, otherwise it may be a heat-seal device that relies on the fabric composition to determine.
Spring installation inserts device and preferably is raceway groove or channel member, it can be around fabric fastening spring installation before or extraction simultaneously.
Fabric tensioning mechanism is preferably in a side and has long arm sewing machine, between the reversible roller spare of fabric approach axis, has a dead man that energy is reciprocal at the opposite side of long arm sewing machine.
Also can use any other suitable tightening device.
The a pair of pressure plate that relatively moves that the spring installation compression set is preferably controlled by air-leg.
According to another aspect of the present invention, a kind of method at fabric intermediate package spring assembly also is provided, this method is included in the middle of a wire joint parallel with spring installation pair of fabric together and inserts a spring installation, fabric around the tensioning spring spare, compression spring spare and the compression in, connect the fabric of being close to compression spring spare, and original connection lead is at the opposite side of spring installation.
Now,, be described in down in company with the scheme drawing reference as an example with one embodiment of the present of invention, wherein:
Fig. 1 is for being used in device of the present invention, a lateral plan of long arm sewing machine.
Fig. 2 is the end elevation of sewing machine.
Fig. 3 is according to the configuration of present device and method, the explanation full figure of first step.
Fig. 4 is respectively the diagram of the second, the three and final step of equipment to Fig. 6.
Assembling of this spring installation and sealed in unit comprise that long arm sewing machine 10, one fabrics that can move back and forth along track 11 transmit and stretching device 12, one a springs insertion device 13 and a spring installation compression set 14.
Always being configured on Fig. 3 of equipment is high-visible.
Long arm sewing machine 10 has the arm 15 of pair of parallel, can pass through two parallel fabrics 16 between this parallel arms, is carrying sewing machine head 17 in the side direction of arm 15.
Needle and platen indicate with 18 and 19 respectively.
Long arm sewing machine 10 can move back and forth along guide rail 11, it is driven by a two-way electrical motor 21, one endless chain 20 and speed-change gear 22, sewing machine 10 form by any suitable mechanical coupling 23 and are connected with endless chain 20, and are equiped with roller 24 along guide rail 11 rollings.
Effective suture length of long arm sewing machine is represented with 25.
Fabric transmission and clamping system 12 include the long arm sewing machine 10 in a side, it has the puller cylinder 26 of the reversible driving of a pair of direction, and at the puller push rod 27 of the opposite side of long arm sewing machine, can be contained on the sliding rack 28 flexibly interspersedly, this sliding rack is moved back and forth on planker 30 by electrical motor 31 and suitable speed-changing mechanism (not shown) drive shown in 29.
It is a raceway groove or channel member 32 that spring installation inserts device 13, available hand or use engine installation, and for example a kind of push rod inserts in two belt straps.This raceway groove or channel member 32 can back and forth pass in and out back and forth by the direction of arrow 33.
Spring installation compression set 14 comprises the air-leg 34 of a pair of two actions, and the two-piston bar label of this device is 35, and the label of pressure plate is 36, and pressure plate is provided with side panel 37, and it guarantees only to have a spring installation 39 or 40 to place in the compression compression apparatus 14 at every turn.
Use the long-armed sewing machine 10 of threading, make lignilite for example to be close to 20 millimeter very effectively near spring installation compression set 14.
In operating process, two fabrics that enter 26 on cylinder are sewn to together at 41 places, and push rod 27 is to insert there therebetween, props up then on sliding rack 28.
First group of spring installation 38 is placed in and inserts two 16 in fabrics (Fig. 4) in raceway groove or the channel member 32 and at compression set 14 places, fabric tensioning around the cylinder 26 controlling spring spares 38, withdraw from raceway groove or channel member 32 then, compression set 14 is used for controlling compression spring spare 38, long arm sewing machine 10 is stitched together the fabric 16 of being close to compression spring spare 38, so that encapsulation spring installation (Fig. 5).
Decontrol compression set 14 then, cylinder 26 and sliding rack 28 make the spring installation 38 that has encapsulated remove (Fig. 6) from sewing machine 17.
So second group of spring installation 39 slips into 16 in two fabrics as previously mentioned, compresses, encapsulate by stitching as previously mentioned, cylinder 26 draws two fabrics 16 before compression and encapsulation, and they are tightened up around second spring installation 30.
It is packaged until whole spring assemblies to repeat above-mentioned steps.
This end product is the spring assembly 38-40 of a series of parallel connections, and they one by one compress encapsulation in 16 in two fabrics.
With the end of the rectangular fabric 16 of spring assembly 38-40, for example with the method closure of making, the spring installation assembling of involution just can be packaged into mattress or other upholster spare later.
