Abstract
Description
- The present invention refers to a machine for preparing net bags filled with products, such as fruits or vegetables, and closed at the top and bottom ends by thermowelding, from a sleeve of thermoweldable netting material, as set forth in the preamble of
claim 1. - A machine of this type is known from EP-A-0302460. This document discloses a machine for preparing net bags filled with products, such as fruits or vegetables, comprising a vertical tube open at its lower end for the introduction of the product into the bag and surrounded by a sleeve of netting material which is withdrawn from the tube by a pair of rollers for the controlled downward feed of the netting material. The machine comprises another two pairs of rollers for drawing down plastic laminar bands and two mutually opposed sliding heads, each carrying a cutter blade to act in conjunction with another fixed blade. During operation of the machine, laminar bands are fed downwardly in front of the sliding heads until the leading edges of the plastic bands are at the same level as the lower edges of the sliding heads. Then, the sliding heads are moved towards each other so that they engage the plastic bands which are adhered to the sliding heads by suction means associated to the sliding heads. Upon further movement of the sliding heads towards each other, the plastic bands are cut by the cutter blades and are subsequently brought into contact with the netting material which is clamped between the sliding heads and then thermowelded along three horizontally extending thermowelding lines by respective thermowelding means disposed in the sliding heads. Upon termination of the thermowelding, the netting material sandwiched between the pieces of cut plastic bands thermowelded thereto is cut between the two uppermost welding lines to separate the net bag filled with products from the trailing netting material which is, by the process previously explained, closed at its bottom end by thermowelding to receive the next charge of products.
- Due to this structure of the machine, the net bags are provided with pieces of thermoweldable band material at their top and bottom ends only.
- From ES-A-8700529, a machine for preparing net bags filled with products is known by which bands of thermoweldable material can be applied to the net bag in such a manner that the bands extend continuously from the bottom to the top end of the net bag. It is neither possible to apply pieces of band material to the top and bottom ends only nor to provide the net bag with a flap suitable for bearing labels and the like.
- It is the object of the invention to provide a machine as set forth above by which, in accordance with the actual desire of the user, thermoweldable band material may be applied to the top and bottom ends of the net bag only, or band material which extends from the bottom to the top, either inside the net bag or outside thereof, or both, or continuously extending band material and band material pieces at the bottom and the top ends in combination, or even band material forming flaps for the application of labels and the like.
- This object is attained by the features of
claim 1. - Preferred embodiments of the invention are subject matter of the dependent claims.
- It is the essential idea of the invention that the machine comprises two feeding paths for feeding thermoweldable band material to the netting material to be thermowelded to close the net bags at their top and bottom ends. Said feeding paths being independent of each other and being selectable at the choice of the user dependent on the kind of equipment of the net bag to be produced by means of the machine. One of the feeding paths is adapted to provide the net bags with pieces of band material at the bottom and top ends only whereas the other feeding path is adapted to provide the net bag with thermoweldable band material extending continuously from the bottom to the top end either inside or outside the net bag, or both. Thus, the second feeding path has a different configuration dependent on whether the band is to be applied inside or outside the net bag.
- The invention is now explained in detail with reference to the accompanying drawings showing a preferred embodiment of the machine.
- In the drawings:
- Fig.1
- shows a frontal view of the machine illustrating the feed path of two bands of thermoweldable material to be applied to the net material outside the net bag formed therefrom and continuously running from the bottom to the top of the net bag;
- Fig.2
- is a similar view showing two feed paths for applying thermoweldable bands to the net bag, one running continuously from the bottom to the top and the other being discontinuously applied to the bottom end and the top end only;
- Fig.3
- is a view similar to Figs. 1 and 2 showing feed paths adapted for the application of two thermoweldable bands which extend continuously between the bottom and top ends of the net bag, one inside and the other outside thereof, and of a third thermoweldable band extending discontinuously in pieces, one being applied to the bottom end and the other to the top end of the net bag;
- Fig.4
- is a view showing the application of two pairs of thermoweldable bands to the net bag, one pair extending on both sides of the net bag outside thereof from the bottom to the top ends and the other pair forming pieces at the bottom and the top ends, wherein one of the top end pieces forms a flap;
- Fig.5
- is a view showing two pairs of thermoweldable band material applied to the net bag, one pair extending inside the net bag between the bottom and top ends thereof whereas the other pair forms pieces at the bottom end and the top end, one of them being extended to form a flap;
- Figs.6 and 7
- illustrate the application of a single thermoweldable band extending between the bottom and top ends of the net bag and a pair of bands applied to the net bag as pieces at the bottom and top ends, wherein one of them forms a flap, wherein Fig. 6 shows the application of the continuous band outside the net bag and Fig. 7 shows the application of the continuous band inside the net bag;
- Fig.8
- shows the application of pieces of thermoweldable band material at the bottom and top ends of the net bag only, whereas one of the top end pieces is extended to form a flap;
- Figs.9 and 10
- are side views; and
- Figs.11 and 12
- are top views of characteristic features of the machine showing details of the band feeding mechanisms.
- In Figs. 1 to 8, the types of net bags prepared by the machine are shown as side views along with machine members.
- In accordance with Fig. 1, bands of thermoweldable laminar material are supplied from
rolls rolls - Cutting and welding of the thermoweldable bands applied externally to the constricted portion 5 of the net bag is conventionally obtained by a movable arrangement comprising a carrying
body 9 provided withthermowelding edges 10, aknife 11, andpunches 12 designed for piercing the bands and the net sandwiched therebetween to form cuts offinger holes - Figs. 2 to 8 show another feed path for
thermoweldable band material 15 by which at least onethermoweldable band material 15 is delivered directly to the cutting and welding area of the machine. The respective arrangement, as shown in side views of Figs. 1 to 10 and top views of Figs. 11 and 12, comprises a rectangular-shapedmetal laminar sheet 13 horizontally arranged and having anentrance edge 14 upwardly curved to receive thethermoweldable band material 15 and the opposite edge 16 being curved in the opposite sense for the delivery of the band material to the cutting and welding area of the machine. - Underneath the
sheet 13 is anothermetal laminar sheet 17 which, together withsheet 13, defines narrow space within which thethermoweldable band 15 is running. - The
top metal sheet 13 is provided with a plurality of rectangular, parallel and equidistant openings through whichannular projections 18 associated to a transverse roller provided on a horizontal shaft protrude into the space defined by themetal sheets band 15, the lower band face being supported by aroller 19, the surface of which is covered with a soft material or the like at at least some annular areas associated to the annular projections ofroller 18. Thereby, a smooth traction of theband 15 is obtained without any possibility of sliding towards the central area of the machine, where the bands of thermoweldable material will be welded to the net material and cut. -
Movable knives 20 oppositely mounted are moved towards each other in synchronism with the other elements of the machine for cutting the band(s) 15 of the thermoweldable material. - It is a characteristic of the machine that no suction cups or other pneumatic members exist in the cutting and welding area since holding of the thermoweldable bands during the implementation of the operations explained above by means of such suction cups or the like is not at all necessary.
- Another characteristic of the new machine is the existence of
rods support 23, saidrods intermediate support 24 which automatically determines their opening or closing in accordance with the actual position of the movable body 9a of the machine when the closing of the net bag and the cutting and welding operations of the bag, along with the bands supplied thereto, is performed. In this way, a smooth tubular constriction and a properly flattened shape of the net material prior to the welding and cutting process is obtained. - The machine can be completed using arrangements performing ancillary operations, such as applying two or more parallel bands inside or outside the bags for carrying advertising information or for providing an aesthetic design thereto.
- The band length of the thermoweldable band material is dependent on whether a handle only at one or the other side of the formed bags is to be prepared or the bag is to be provided with a flap for having labels affixed thereto or information printed thereon. The band length is adjusted by means of
pneumatic cylinders 25 at each side of the machine, horizontally supported and having the cylinder shaft perpendicular to the travel of netting material upon forming the net bags, saidcylinder 25 being supported by asupport 26 fitted to amovable arm 27 sliding on fixed guides affixed to the machine frame. Thepneumatic cylinder 25 houses a piston having astem 28 provided with arack length 29 and a threadedlength 30 at its end which allows the adjustment of the piston's forward travel relative to anabutment member 31 by means of one or two adjustement nuts. In this way, the amount of rotation of a guidingroller 32 associated and meshing with the rack is determined and thereby, the amount of rotation of awheel 33 and of aroller train - From aforementioned Figs. 1 to 8, the travel of the bands of thermoweldable material fed to the netting material is well understood. The result obtained by the various kinds of band feed is understood from the side views and profiled views of net bags shown in figs. 1 to 8.
- As may be learned from Figs. 3 to 7, the net bags may be provided with thermoweldable bands inside as well as outside the netting material forming the net bag. According to these figures, at least one thermoweldable band may be provided by a
roll 34 or two bands may be provided byrolls - From Figs. 1 to 8, the manner in which the bands of thermoweldable material supplied by
rolls metal sheets slots plates latter plate 39 is provided withextensions 40 determining a centralrectilinear area 41 adapted to the lower portion of the netting material 7, promoting in this way the constriction of the netting material before clamping same betweenclamping bodies 9 and 9a prior to the welding process. - The bags according to Fig. 1 are provided with two rectangularly-
shaped side bands 42 fully extending over the bag and its contents, whereas the bag according to Fig. 2 has one band continuously extending from the bottom to the top ends outside the net bag, and the bag of Fig. 3 has one band continuously extending outside the bag from the bottom to the top ends, whereas another band extends inside the net bag from the bottom to the top ends, the latter being supplied byroll 34. - The bag according to Fig. 4 is externally provided with two
bands rolls areas - The bags prepared by the machine of the invention are provided with two or more continuous or
discontinuous welding lines welding bands 10 of theactive clamping body 9 which is additionally provided withpunches 12 for punching cuts forfinger holes top edge 52 and thebottom edge 53 of the pieces of thermoweldable band material welded to the top and bottom ends of the net bag are formed by cuttingknife 11 associated to the clampingbody 9, whereas thebottom edge 55 of the pieces ofthermoweldable material 15 welded to the top end of the net bag are formed by cuttingknives 20. - At the bottom end of the bags, the
welding line 54 puts together the thermoweldable band material with the net material 7 forming the bag. It may be seen from the figures thatknife 11 is located between thewelding projections 10 producing the weld lines 48 and 54. - The length of the
flap 56 according to Fig. 5 can be adjusted by governing the stroke of therack 29 associated to the respectivepneumatic cylinder 25, and the flap can be used for affixing alabel 57 thereto containing optional inscriptions and graphics or a bar code. - In the case of fixing labels, for instance, at the
flap 56, an ancillary arrangement can be used, which is not illustrated in the drawings, which might improve easy placing of labels without any wrinkles and based on the operation of small pneumatic cylinders.
