Detailed description of the invention
Goods are transferred to the sack filling machine at the loading station place being positioned at described machine in the vertical along conveyer.Usually, sack filling machine comprises a bag feed conveyor.The wire of empty bag is loaded on bag feed conveyor.Wire is transferred in sack filling machine by bag feed conveyor, is usually undertaken by being namely substantially perpendicular to longitudinally transmission wire in the horizontal.
Each wire dispenser for bag comprises at least one wire spool that flexible pouch stacks (each bag has at least one hole) and is positioned through described hole.Usually, wire dispenser for bag comprises two wire spools, is positioned through pair of holes in each in flexible pouch of described wire spool, as US 3, and 918, shown in 589.
Usually the top of wire spool and load station clamping pin lower end between will there is about 1mm to 5mm, the small―gap suture of about 2mm usually.This small―gap suture is required when next wire dispenser for bag is transferred in the loading station of sack filling machine in the horizontal, to avoid the interference effect between spool head and clamping pin.
If not by accurately and be intactly delivered on clamping pin, then there is problem in bag.Bag may slip over the gap between the top of spool and clamping pin, and result is bag filling process failure and causes the generation of product waste material.High scrap rate is uneconomic, thus should avoid.
The most normally, wire dispenser for bag comprises and is arranged on platen and separates two wire spools of fixed range.Fig. 1 shows an example of current wire spool 1, and it is for transmitting and supply the industry of empty flexible pouch.Spool 1 comprises two critical pieces: reel body 3 and spool head 4.Reel body 3 and spool head 4 can be completely separate from each other to be loaded on reel body 3 by empty bag, then ressemble so that closed spool 1 prevent bag from departing from spool 1, until when using.Bag perforation is porose, and the diameter in described hole is greater than the diameter of reel body 3, but is preferably slightly less than the full test diameter of spool head 4.Preferably, the plastic foil of adjacent bores comprises weak line, such as line or perforation.
Fig. 2 shows an example according to wire spool 11 of the present invention.When flexible pouch is from when stacking by lifting, described hole is passed through along reel body 13 and is caught spool head 14, therefore promotes spool head 14 and moves axially it relative to reel body 13.Spool head 14 is promoted to the second place from its primary importance.Subsequently plastic foil pliability and/or allow spool head 14 through hole along the local laceration of weak line, on clamping pin bag can being passed to load station.Preferably, spool head 14 contacts clamping pin 15, thus eliminates any gap between the free end of spool head 14 and the end of clamping pin 15.Flexible pouch is crossed spool head 14 by transmission and is transferred on clamping pin 15, and spool head 14 can freely return back to its primary importance subsequently.
Preferably, the primary importance of spool head 14 is lower position, and the second place of spool head 14 is upper position.In this case, spool head 14 is under gravity freely from its second site reversion to its primary importance.Such as, but can be susceptible to other arrangement, wherein by the power outside gravity is biased, from its second site reversion to its primary importance, spool head 14 can be spring-loaded spool head 14.
The loading station of sack filling machine comprises clamping pin 15, and described clamping pin is isolated and corresponds to the spacing of spool 11.At loading station place, bag is passed through spool head 14 from reel body 13 singly, and is passed on clamping pin 15 as above.In order to open each bag and keep bag for what open, bag is passed and bag is fixed by the hole on clamping pin 15, and keeps fixing during bag is filled.
