Based on the Fig. 5 to Fig. 7 of perspective schematic view of the method shown bottom the bag opened in bag assembling facility, illustrate in greater detail now in this facility have according to guide rail 30 of the present invention, according to of the present invention for carrying the advantageous use of the device 1 of tubular bag body.
In Fig. 5, can see according to conveying device 1 of the present invention be integrated in wherein bag assembling facility bottom open platform.Conveying device 1 comprise conveyer belt form conveyer 2 and with transfer rate V continuous moving on direction of transfer T.Tubular bag body 10 lies low on conveyer 2, its traversed by extending longitudinally and direction of transfer T, tube wall 10a, 10b mutually against.On a moving belt, bag 10 is fastening in case sliding stop by unshowned holding device.This holding device comprises the band that such as ferromagnetic material is made, the band that this ferromagnetic material is made is placed on bag 10 and by the magnet of movement together with driving-belt and draws towards conveyer belt from the bottom side of conveyer belt, and thus the bag 10 between them is pressed to conveyer belt.Alternatively, conveyer belt is formed as conveyer belt of boring a hole, and wherein applies the vacuum of being aspirated towards conveyer belt by bag 10 from the bottom side of conveyer belt.
Tubular bag body 10 is by the fabric manufacture of such as stretching plastic tape.Plastic tape can comprise polyethylene or polypropylene material or PET.Optionally, fabric has the coating of synthetic material.Alternatively, tubular bag body 10 can by the compound manufacture of plastic foil or plastic fabric and plastic foil.
Tubular bag body 10 has two unlimited end regions 10e, 10f, the end regions 10e in end regions 10e, 10f respect to one another will be formed as intersecting bottom.In further process, end regions 10f also can be formed as intersecting bottom to prepare box bag or box valve bag with end regions 10e similarly.
Be arranged in conveyer 2 upstream and in unshowned folding table, be arranged in the transport process between on conveyer 2 two guide rails 30 at bag 10 on direction of transfer T, end regions 10e has substantially upwards folded 90 ° and has been held in place on conveyer 2.Two guide rails 30,30 arranged parallel to each other.As illustrated by Fig. 1 to Fig. 3 above, each guide rail 30 has compressed air piping 31, and compressed air piping 31 extends in the axial direction and is connected with compressed air source in pipe 35.From compressed air piping 31, extend transversely through tube wall from the air nozzle 32 of compressed air piping 31 air feed, multiple small through hole form outside, and generation is pointed to the direction (only symbolically illustrating) of direction of transfer traversed by and is extended across the air-flow L of the whole length of guide rail 30,30.
By with reciprocating aspirator 13,14 on the direction of direction of transfer T traversed by, two tube walls 10a, 10b are pulled open away from each other, and the end regions 10e of bag 10 is opened thus.Except their transverse movable, aspirator 13,14 also can move with transfer rate V on direction of transfer T, so that tube wall 10a, 10b can not distort in opening procedure.
Process is that two aspirators 13,14 contact with the second tube wall 10b with the first tube wall 10a respectively from the opposite side of end regions 10e.Vacuum is excited, so that the first aspirator 13 aspirates the first tube layer 10a and the second aspirator 14 aspirates the second tube layer 10b.It should be noted that aspirator 13,14 and conveyer 2 on direction of transfer T with transfer rate V synchronizing moving.Then, two aspirators 13,14 with the direction of direction of transfer T traversed by start mobile away from each other, each aspirator moves along tube wall 10a, 10b thus, and therefore opens the end regions 10e of tubular bag body 10.
Fig. 5 shows the end regions 10e of the tubular bag body 10 under open mode, is wherein formed with gap 10g between tube wall 10a, 10b.Also can see in the figure, simultaneously, vacuum is sucked device 13,14 and removes, and two aspirators 13,14 remove they oneself with the joint of tube wall 10a, 10b, and therefore two aspirators 13,14 can against direction of transfer T upstream movement with the end regions opening next bag.In addition, also can see in this figure, the end regions 10e opened has the geometry do not limited to a great extent.Now, widener 21 is inserted the gap 10g of the end regions 10e opened, wherein widener 21 moves into the end regions 10e opened along circular arc (arrow P 3).The arc of widener 21 moves to comprise thus and points to direction of transfer T and the high mobile component of relative velocity ratio transfer rate V.Widener 21 is driven by rotation cingulum 25, and cingulum 25 is directed on direction of transfer T by two cingulum dishes 26,27.Each pulley in pulley 26,27 is connected with can control to drive, so that be advanced through the circulation synchronous of bottom device for opening 1 at widener 21 and bag 10 while, widener 21 can accelerate relative to transfer rate V and slow down.
As ise apparent from FIG. 6, widener 21 around pulley 26 run after, the circular arc of widener 21 move become by cingulum 25 compared with low cruise promote the translation on direction of transfer T.Owing to still there is the relative velocity higher relative to transfer rate T, widener 21 moves quickly than bag 10, and the inside therefore in the front portion of the end regions 10e opened facing to tubular bag body is upwards run, the front portion of end regions 10e is widened as front angle blade 10j by widener 21 thus, and the shape of front angle blade 10j is isosceles triangle substantially.
Fig. 6 to show wherein angle blade 10j by state that widener 21 is fully formed.It can be seen in this figure, the isosceles triangle shape of front angle blade 10j is located symmetrically relative to the center line M of the end regions 10e opened.This center line M is accurately between two guide rails 30.By forming first three dihedral angle blade 10j, the front area of the first tube wall 10a folds around a guide rail 30 and turns back on himself simultaneously by widener 21.Similarly, the front area of the second tube wall 10b is folded into the home position on the horizontal plane of bag 10 by widener 21 substantially around another guide rail 30.Like this, the state shown in cross-sectional view of Fig. 1 is achieved.The folded part of tube wall 10a, 10b forms the bottom side wing 10u, 10t.When the bottom side wing 10u, 10t of tube wall slide along support portion 34, the bottom side wing 10u, 10t of tube wall are pulled to support portion 34 by the air-flow L that guide rail 30 produces and on support portion, remain the shape of restriction.
After first three dihedral angle blade 10j is formed, widener 21 moves backward and shifts out front angle blade 10j by slowing down relative to transfer rate T, and widener 21 continues to fold tube wall 10a, 10b downwards, and therefore two tube layer 10a, 10b continue to form the bottom side wing 10u, 10t.Before in the past angle blade 10j recalls widener 21, the top 10s of front angle blade 10j has arrived compressorium 28, and first whole front angle blade 10j is remained the shape of restriction and prevent front angle blade 10j from not folding by top 10s by compressorium 28 subsequently.In this embodiment, compressorium 28 has the compression band be oriented on direction of transfer T.By transmitting bag 10, the whole end regions 10e of bag 10 is pulled to below compressorium 28 along bottom centre line M, and the shape and preventing that folding thus the bottom side wing 10u, 10t also remain restriction does not fold.
Fig. 7 shows machining state, wherein widener 21 has been moved to the end regions 10e opened of tubular bag body 10 on direction of transfer T with speed V2R, speed V2R low or more negative than transfer rate V until it runs to the rear portion 10h (as seen on direction of transfer T) of the end regions 10e opened and the rear angle blade 10p widened by rear portion 10h thus as basic isosceles triangle form.As can be seen from Figure 7, at this moment the formation of two the bottom sides wing 10u, 10t also completes.
In as can be seen from Fig. 5 to Fig. 7, when bag moves on direction of transfer T, laterally folding downwards the bottom side wing 10u, 10t are fastened on the position of restriction by guide rail 30.Bag 10 on direction of transfer T by transmission time, this is fastening is produced by air-flow L, and air-flow L produces negative pressure in support portion 34 and between the bottom side wing 10u, 10t, and the bottom side wing 10u, 10t are pressed to support portion 34 by this negative pressure.The wing 10u, 10t remain on its restraint location in bottom side, stop and the therefore compressorium 28 that also stops of air-flow L until their arrive guide rail 30 at this.Therefore, also prevent the slip of the center line M of bottom fold.Fastening the bottom side wing 10u, 10t of opening and center line M are conducive to forming geometrically accurate angle blade 10j, 10p by widener 21.Because guide rail 30 arrives as far as compressorium 28, in the forming process of whole bottom, the bottom side wing 10u, 10t keep fastened.Like this, ensure that the accurate geometry bottom bag is shaped.Produce the whistle occurred in the process of air-flow L to be minimized by air swirl element 33, and therefore for staff, noise is created disturbances to and is reduced in a large number.
