VEEPAGKUNQSHASCHINE FOR PACKAGING GOODS IN SGHEUMPFOLIE

There is a wide variety of ■ packaging systems on the market of goods to be found in shrink films and foils. Below I want briefly explain some of the known machine systems here »

1.) Banding machine for packing goods in shrink film »This machine system works from 2 flat films and forms around the Paekgut a banderole, that is, the sides of the goods, are not locked. The film hangs a little over the sides of the packaged goods «. This package then runs through a shrink channel and the ^ The film now shrinks skin-tight to the package. This packaging is called

banding packaging, as this package is not fully wrapped and the right and left sides of the packaged goods are not wrapped in foil.

2.3 Packaging machines for packaging in hull film and other films al al full wrap machine

The full wrapping machines known to me work in the following principle » The goods are transported through a film curtain that extends from has formed two flat films »This creates a band around the package»

On the sides of the packaged goods are written depending on the height of the packaged goods matched slides over.

3 «) Packing machine for packing goods in shrink film with self-adjustable side sealing station This machine works from two flat foils. The packaged goods are through A film curtain is pushed and a building roll is formed around the packaged goods.

The film protrudes on the sides · The width of the overhangs of the film on the sides depends on the height of the package. After the banding, the packaged goods are not transported straight ahead, but apfXMX transversely to a side sealing station. A photocell that scans the packaged goods is attached in front of the side sealing station. If the packaged good has reached the photo cell, an impulse occurs which causes the welding jaw to come into action and the first end of the packaged good is welded shut. After this welding, the paokgut is transported and the photo cell scans that the goods are found. "Then" the second face is welded and a bag closed on all sides has been formed around the paokgut. After this process, the packaged goods are transported through a shrink channel and the film shrinks skin-tight to the packaged goods. It is still possible to suspect that the transverse transport of the goods and through

The machine described under 3 has the disadvantage that it is through the transverse transport adjusts itself to the different .Packaged good sizes, but this principle also slows down the operation. Because 1. x ± xk it only works with one welding jaw, the two end faces must be welded and 2. must the flare first the conveyor belt, the carries out the transverse transport of the goods to the end face welding, pass, before the next packaged item can be inserted · This means that the machine works with very small quantities. Also is at this machine the difficulty of "slipping and falling apart" Difficult packaged goods are no better solved than with the machine described under 2.

With the packing machine I developed for packing goods in shrink films and other films, these problems are said to be as simple as possible Way to be solved as far as possible.

My packaging system (A, Bu. C) works from 2 flat films, one Foil suspension is attached above the machine (3) and one Foil suspension is attached below the machine (1).

The foil suspension is designed so that you can immediately

Place two rolls of film on both the top ( k ) and bottom (2) Jj

can "This means that when the format of the foils is changed, the '"

Slides not required as often. -

The packaged goods are now placed on the transport table (7) up to the rear stop. A photocell or a contact now triggers the slide action (5) and the packaged goods (kO) - see also drawings E, F, G and Ή for how it works - is formed by a film curtain, the upper film (3) and lower film (6) , pushed onto the conveyor belt (13) (drawing B as well as, F 1 and F 2) _o The slider (5) pushes the packaged goods until just behind the welding system (8 + 9) where now by welding the upper and lower foil a Banderole is formed around the packaged goods o During the banding, the packaged goods are banded and in addition the upper and lower film are now connected to one another and a new film curtain is formed, which is necessary for the banding of the subsequent façade goods o The rockers and film guides (11 + 12 ) keep the film curtains so tight that they do not form creases when the goods are packaged. I would like to mention that instead of the transport table, a conveyor belt can also be attached ₉ which automatically feeds the packaged goods to the machine ο This conveyor belt goes up to the stop and the slide (5) f now pushes the packaged goods ( ¹ K)) through the film curtain , as already described. "

After the packaged goods are banded, they lie on the conveyor belt (13) - drawing B) and are transported to the second welding station (upper jaw 15, lower jaw 16) after inserting the next packaged goods is packaged goods (IFO) with its foil overhangs, right and lin ks (3) at the welding station, a cylinder actuator (18) and (17), the top u _o Unterbaoke setzeno for the welding of the sheets in activity This Stirnseitenversohweißung has become so possible , because when banding on the right and left of the packaged goods, this should be emphasized again, a film overhang (3) was formed on number FJ 2 _o The size of the film overhang is different depending on the height of the packaged goods film width of the upper and lower film _o dependent course is nöoh to mention a more mechanical actuation of Sehweißsysteme It is possible that the transport belt (13), which transports the goods to the whitening station, is not interrupted lengthways and is exactly as wide as the maxο paokformato The transport belt is driven by deflecting shafts (*) or kept in the lane

J ^ v ,. . 109 837/07 39,

After the right end face (G 2) has been welded, the packaged goods are transported onto another conveyor belt (23), drawing G. This conveyor belt is also driven by shafts (24). The third welding station, which now welds the packaged goods on the left side, is attached to this conveyor belt. ( S ₀ also drawing H 2.

Lower jaw (20) and upper jaw (19) are connected by cylinders (21) (22) actuated. Also here is a mech. Actuation possible. The welding is possible because here too there is a film overhang Packaged goods, as previously mentioned, are located. Because the packaged goods that are to be packed vary in size are, the welding jaws (upper and Inter-jaw,) can be adjusted to the different sizes. These Adjustment is carried out as follows.

1.) The conveyor belt (23) is connected to the welding jaws (upper and lower jaw) on a slide (25). Depending on the size of the packaged goods, the conveyor belt and the sealing jaws can be set to the right, ie in the direction of the arrow, mechanically by means of a crank (27), but also electrically or electronically to the packaged goods size. This stepless adjustment is made possible by the sliding cams (26). The infinitely variable adjustment of the conveyor belt means that practically any size of goods can be packaged, and it has also become possible to weld the foils so close to the packaged goods that the packaged goods can be tightly wrapped.

It should also be mentioned that this adjustment option since the conveyor belt (23) is not interrupted in the longitudinal direction and thus the packaged goods x ± xk with the entire area on the conveyor belt rests.

After this 3 · weld, a fixed tight-fitting Zuer bag is now t been formed around the package. The packaged goods are now placed in a shrink channel

(D) transported, and the film becomes even tighter (skin-tight) due to the heat the packaged goods have shrunk.

The shrink channel (drawing D) has the following important points ^.

Silicone coated rods (32) which can withstand an extremely high temperature « convey the packaged goods through a hood (31) in which the for the film thickness is certain heat. It is controlled from the switch box (33)

Depending on the packaged goods, however, this described machine does not always require shrinkage because the packaged goods are removed from the packaging machine has already been packed so tightly that additional shrinking is not necessary for some packaged goods. I am thinking primarily of textiles and to packaged goods that can be damaged by shrinkage.

Below I would like to briefly review all the advantages that are compared to each other have crystallized out from other packaging machines on the Harkt, list them in a table.

Io) There can be conveyor belts for goods of different lengths and widths be used, which full the entire area of the largest Paokgutee

take up.

This is of great benefit in the case of packaged goods that fall apart easily. Even with packaged goods that slip easily, such as B. on both sides

With coated paper blanks, the advantage is obvious.

2.) The infinitely adjustable conveyor belt with coupled welding system makes it possible to pack any size of packaged goods. Furthermore, due to the infinitely variable adjustability, the welding system (β. Drawing C) can be brought so close to the goods that the goods can be wrapped very tightly.

109837/073 9

3) It should also be mentioned that the height of all 3 welding stations is continuously adjustable, either mechanically or electrically.

* l ·.) Since the machine is designed in 3 stages, it can be built on a modular basis be put together.

a ·) 1 · stage banding station (drawing A) b.) 2 »stage 1. side welding station (drawing B) ■ c.) 3 · step 2. side welding station (drawing C) d.) h» stage shrinking system (drawing D) This The modular principle is of great benefit with / k transport, because the system can be divided into 3 or h stages without any special requirements. In 3 stages without shrinking system, in h stages with shrinking system »The machine with the 1» level can only be used as a banding machine »

Coupled with level 2, it can also be used, for example, for textile ballenyer packaging. The textile bales are sometimes packed in such a way that one / front side is not welded shut so that the label hangs out. The system £ Level 1 + 2) is also used where only one bag is to be formed. The stages 1, 2 and 3 coupled with each other form a full wrap machinej with D (or »stage h) coupled with subsequent shrinkage ·, m

I believe that this invention of packaging goods in Films of all kinds on the market are a real innovation and rationalization will provide.
