Abstract

The method for the packing of piece products of especially soft consistency entails first positioning the piece product (6) by its underside on the packing material extending in a horizontal plane and then moving it forwards through a fold coulisse so that the packing material (4) is folded upwards in the direction of the side and end faces (14,16) of the piece product. The sections of the packing material lying against the end faces of the piece product protrude upwards. Independent claims are included for the following: (A) a device to carry out the aforesaid method; and (B) a packed piece product made available by the aforesaid method.

Description

The The invention relates to a method for packaging piece goods, in particular of general cargo with a soft consistency, in which a flat packaging material is positioned under the formation of fold lines on the outer surfaces of the piece goods such that this from the packaging material ultimately completely and in particular tight fitting is enclosed. Furthermore, the invention relates to a device to carry out of such a method as well as a packaged with this method General cargo.

It is known, general cargo of different Art at least largely automated with paper or foil too to offer them for sale in packaged condition to be able to. Usually In a packaging process of the type mentioned the piece goods by a directly adjacent to him piston pushed through a Faltkulisse, wherein at the beginning of this process between Faltkulisse and general cargo the Packaging material is positioned so that this together with the general cargo is moved through the Faltkulisse. In this way it is achieved that the packaging material adheres to the side surfaces of the Piece goods applies. As a result, the packaging process is then completed by that one surface of the piece goods, which in the movement through the folding gate in direct contact with the piston, manually or by means of a suitable device covered with packaging material, so that the piece goods then Completely is packed.

Especially if food products such as e.g. soft cheese should be packed, is disadvantageous to the described packaging process that the the food product through the Faltkulisse moving piston in direct contact with the food product, resulting in a Contamination of the products to be packaged. Particularly disadvantageous is in this context that one and the same piston successively during the respective packaging process must touch all products to be packaged.

Farther is often not achieved with the known packaging methods, that the packaging material directly and without relevant air pockets on all surface areas of the piece goods to be packed is applied. this leads to especially with packaged pieces of cheese, that in the area of the air bubbles one by an unwanted Maturation conditional discoloration which consumers ultimately perceive as a quality defect is perceived.

Finally is it is not without known packaging methods and devices further possible, as part of a continuously automated process such Pack general cargo, have varying within certain tolerances dimensions.

A The object of the invention is a method of the initially mentioned type and an apparatus for carrying out such a method which makes it possible Piece goods without to pack the occurrence of contamination. Additionally or Alternatively, it should be possible according to the invention Piece goods, preferably piece goods with varying dimensions, avoiding disturbing air pockets so To pack that packaging material as completely as possible directly at all surface areas of the piece goods is applied.

The mentioned contaminations are inventively avoided by the cargo first with its bottom on which is essentially in one positioned horizontally extending packaging material and then with moving the underside forwards through a folded backdrop, so that the packaging material starting from the bottom of the unit load is folded up in the direction of the side and end faces.

According to the invention, it is thus avoided that a piston, which moves the piece goods through the folding gate, comes into direct contact with the piece goods, since the packaging material substantially aligned in a horizontal plane, then the piece goods positioned on the packaging material and then moved relative to the Faltkulisse is that the cargo with that side passes through the Faltkulisse through which it was previously placed on the packaging material. Such a movement can be achieved, for example, by supporting the piece goods resting on the packaging material from below by means of a piston which is lowered onto the packaging material through the folding gate after the piece goods have been placed on the packaging material, wherein the piece goods gravitate on the packaging material or Piston remains lying and thus is moved together with the piston and the packaging material through the Faltkulisse. In this case, the Faltkulisse causes a folding of the packaging material up in the direction of the adjacent to the underside of the cargo side and end surfaces, being ensured during this folding process due to the packing material located between the piston and cargo that the cargo is not touched by the piston. After said folding process can then by means of suitable measures, the underside opposite the top of the piece goods on the implementation knows terer folding operations are covered with packaging material.

alternative to the described lowering of the piston through the Faltkulisse through it is also possible execute the piston, for example, as a static support surface and to move the folding gate upwards relative to said supporting surface, so that the bearing surface, the packaging material on it and that on the packaging material general cargo also be moved through the Faltkulisse. Also in In this case it is avoided that the cargo is touched by the support surface.

The Faltkulisse is preferably carried out such that the packaging material first in the direction of the side surfaces and subsequently in the direction of the faces of the piece goods is folded, the side surfaces usually have a larger surface area as the end faces.

To the caused by means of Faltkulisse folding process are the the side surfaces of the piece goods adjacent sections of the packaging material usually after above, so that the protruding Sections can be used to cover the top of the piece goods.

Prefers It is there when, after the folding process caused by the folding gate also on the front surfaces of the piece goods projecting portions of the packaging material up, so that even these sections are used to cover the top of the piece goods can be. It is particularly advantageous if the first in the faces protruding upwards Sections of the packaging material towards the top of the unit load be folded before protruding upwards in the area of the side surfaces Sections of the packaging material towards the top of the Piece goods folded become. In this way, the front-side protruding sections through protruding in the area of the side surfaces Sections, so to speak on top of the piece goods fixed. An unintentional release the front-side portions of the packaging material from the end faces is on counteracted this way, so that the voltage applied to the front and side surfaces Sections of the packaging material together with those on the bottom of the piece goods adjacent region of the packaging material a stable cup-shaped receptacle form, for example, in the packaging of soft cheese no liquid or whey can escape.

The both in the area of the opposite side surfaces above protruding Sections of the packaging material can be so close to each other until they are folded together to complete the top of the piece, in particular each half, cover. It can then the end portions of the packaging material in mutual Plant from the top of the piece good, preferably about at right angles, stand out. This allows grasping the packaged unit load in the area of said end sections, without the packaging material from general cargo can solve. If in this case the original frontally upwardly projecting sections the packaging material in the manner already explained on the top of the piece goods are fixed, is also in the said gripping the end portions the packaging material ensures that the packaging material not from the piece goods at the front can solve.

Especially it is preferred if the projecting from the top of the piece goods End portions of the packaging material extend through a gap and at its edge region protruding from the gap by means of at least held in a gripper and in a direction perpendicular to the top of the piece goods be pulled until the top of the piece goods associated sections of the Packaging material as possible entire area abut on this top. By this drawing process is achieved that between all surfaces of the unit load and the packaging material is as good as no air left and the packaging material is fully applied to all sides of the piece goods. This avoids particularly when packing soft cheese, that unwanted maturation processes and discoloration occur.

One positive secondary aspect of the latter variant of the method exists in that in the described drawing process, during which the cargo on its underside no longer prefers a piston or a support surface supports is the bottom of the piece goods something bulges down, so that it will ultimately be given a bulbous shape, the End user the impression of an individual hand wrapping awakens. Farther it is in the described method variant of advantage that they also in general cargo with in a certain tolerance range, which e.g. 10%, varying dimensions works. It just gets that long pulled at the end portions of the packaging material until the the top of the piece goods as far as possible associated sections of the packaging material entire area abut on this top. So regardless of the actual Size of the piece good one all-over Attachment of the packaging material on all sides of the piece goods reached.

The described method of drawing According to the invention, the packaging material through a gap can also be used in packaging processes in which a piston or a bearing surface directly touches the piece goods during the packaging process. Such a method is described in claim 8.

At the Pulling the packaging material through the mentioned gap is preferred between two sealing jaws movable parallel to the top of the piece goods formed, which are in mutual contact end portions seal the packaging material together after the drawing process is completed and the sections of the top of the piece goods assigned Packaging material as possible entire area abut on this top. While of the drawing process In this case, the sealing jaws are closed incompletely, so that a movement of the packaging material in between the sealing jaws trained gap is still possible then the sealing jaws are completely closed to then perform the sealing process, which the end portions of the packaging material in a possible close to the top of the piece goods connecting area lying together.

Of the Sealing process, for example, using heat, cold sealing varnish or preferably carried out by ultrasonic waves. The usage of Ultrasonic waves or the use of an ultrasonic welding process is particularly advantageous if wet cargo, such as whey wetted soft cheese, because the use of ultrasonic waves ensures that the effect of the sealing process by the presence of moisture is not affected.

To the sealing process can the still protruding areas of the packaging material in the direction the top and possibly the end faces of the piece goods are folded until they come to the plant there, so that the packaged cargo ultimately essentially has the shape of the unpackaged piece goods.

The The present invention also relates, inter alia, to devices to carry out the already explained Method. Such a device can for example be a folding backdrop have, through which the cargo together with the packaging material in the already described Way under gravity is moved through. alternative the Faltkulisse can also be performed relative to the cargo upwards movable.

The Faltkulisse preferably has four guide elements that the Front and side surfaces of the unit load are assigned and tapered in the direction of movement of the piece goods converge. This conical training is the particular elastic or deformable cargo in the lower area of the folding gate bruised slightly from all four sides, what a direct and close concern of the packaging material the front and side surfaces of the piece goods ensures.

Of the Beginning of the effective range of the guide surfaces associated with the guide elements can be opposite the beginning of the effective range of the guide surfaces associated with the side surfaces in the direction of movement of the piece goods be offset. This requires that the packaging material first in the area of the side surfaces and subsequently in the area of the faces is folded upwards.

It is preferred when the guide surfaces associated with the side surfaces as encircling bands and the faces associated guide elements as static guide plates are formed. in principle can however, all guiding elements both static and wrap around bands.

Of the already explained Piston, by means of which the piece goods along with the packaging material through the Faltkulisse can be lowered is preferred with a vacuum suction for between Piston and piece goods located Packaging material equipped, allowing relative movements between Packaging material and piston during the movement through the Faltkulisse be effectively avoided.

Below The Faltkulisse can be a the general cargo be provided receiving form, which in their vertically extending Edge areas slots for the passage of superior Has packaging material sections.

The Invention includes in addition to the described method and devices also general cargo, which with a method according to the invention were packaged or packaged piece goods, which by a method according to the invention available are.

Further preferred embodiments The invention are specified in the subclaims.

The Invention will now be described with reference to an embodiment with reference explained on the figures; in these show:

1 a three-dimensional view of a piece of goods to be packaged, which rests on a portion of a packaging material, the an endless track is formed,

2 a three-dimensional view of a Faltkulisse invention with underlying arranged form,

3 a view of the end face of an arrangement according to 2 .

4 a three-dimensional view of an arrangement according to the 2 and 3 with partially packaged piece goods in the mold,

5 the in-form, partially packed parcel according to 4 omitting the folding scenery,

6 a three-dimensional view of a partially packaged piece goods with mutually adjacent end portions of the packaging material,

7 a three-dimensional view of an apparatus for pulling the end portions of the packaging material according to 6 through a gap formed by sealing jaws, and

8th a three-dimensional representation of individual process steps of the entire packaging process, in which case only the packaging material is shown with the omission of all device components.

1 shows the end of an endless track 2 from packaging material, which may be formed for example as a packaging film. From the endless track 2 become by successive cutting and punching operations adjacent packaging material units 4 generated, each for packing a piece goods 6 serve.

To produce the individual packaging material units 4 be in the endless track 2 Sections running perpendicular to their longitudinal extent 8th introduced, which extend only over a central region of the continuous web, so not up to the edge. After introducing these cuts 8th be on both sides in the edge regions of the continuous web 2 outs 10 introduced, which is up to the cuts 8th extend so that the punched out 10 together with the cuts 8th a packaging material unit 4 completely from the subsequent packaging material unit 4 split off.

On a packaging material unit 4 is centrally a cuboid general cargo 6 with its bottom 12 (please refer 3 ) hung up. To the bottom 12 borders at right angles to each other opposite side surfaces 14 and opposite faces 16 on, with the longitudinal extent of the side surfaces 14 larger than that of the faces 16 , faces 14 and end faces 16 are the same height and perpendicular to a top 18 of the piece goods 6 at which of the bottom 12 opposite.

cargo 6 and packaging material unit 4 are sized so that the general cargo 6 not covered, on every side surface 14 adjacent section of the packaging material 4 has a length a, which is greater than the height h of the piece goods 6 , Correspondingly, the length of the piece goods 6 uncovered portion of the packaging material 4 , which on each end face 16 of the piece goods 6 adjoins with a length b also longer than the length h of the piece goods 6 , Through the punched out 10 become in those peripheral areas of the packaging material 4 which faces the faces 16 are assigned, tabs 20 formed, which contribute to the achievement of said length b.

Due to the dimensions of general cargo 6 and packaging material 4 is achieved that when the packaging material on all four sides of the piece goods 6 in the direction of the side surfaces 14 as well as the front surfaces 16 is worked out, the packaging material 6 over the top 18 of the piece goods 6 protrudes, so it also in the episode even for covering the top 18 can be used. This circumstance is particularly explained by the below 5 and 6 clarified.

2 shows a three-dimensional view of a Faltkulisse invention 22 located below a packaging material unit 4 according to 1 which in turn extends in a horizontal plane, and on the central a general cargo 6 according to 1 rests. The packaging material unit 4 with the piece goods on it 6 are in the area of the piece goods 6 through an in 2 for reasons of clarity, not shown supported piston from below, wherein the size of the piston surface is chosen so that it is substantially the dimensions of the bottom 12 of the piece goods 6 corresponds and through the Faltkulisse 22 can be moved through.

The folding backdrop 22 has four guide elements, two of which are the end faces 16 and two the side surfaces 14 of the piece goods 6 assigned. The faces 16 associated guide elements 24 are designed as static guide plates, which a funnel-shaped receptacle for the cargo 6 form, with the lower sections of the guide plates 24 tapering towards each other. The mutual distance of the lower Be rich of guide plates 24 is dimensioned slightly smaller than the length of a side surface 14 of the piece goods 6 so this through the guide plates 24 in the lower area something is squeezed.

The side surfaces 14 associated guide elements are as by two axes (of which in 2 only one is shown) circumferential bands 26 formed, which also taper in their lower portion conically. The mutual distance of the bands 26 in the lower area is dimensioned slightly smaller than the width of the piece goods 6 or as the length of the faces 16 of the piece goods 6 so that the piece goods 6 when passing through the Faltkulisse 22 also in a parallel to the faces 16 running direction is slightly squeezed.

In the vertical direction are the guide plates 24 and the ribbons 26 arranged so that a moving from top to bottom cargo 6 first in the effective range of the bands 26 and only then in the effective range of the guide plates 24 arrives.

Below the fold gate 22 is one for taking a piece goods 6 suitable cuboid shape 28 provided, which consists essentially only of side walls and is open at the top and bottom, so that a piston with downwardly extending piston rod together with a piece goods thereon 6 through the form 28 can be moved in the vertical direction. Form 28 has in its four vertical edge regions each have a slot 30 for the passage of protruding packaging material sections, which in particular 5 is apparent.

The above in connection with 2 described device is in 3 shown in a frontal view. Well visible in this view, the two in their lower part conically tapered bands 26 as well as the slots 30 the form 28 ,

When packing a piece goods 6 this one with its bottom 12 proceeding by a lowering of said piston in the range of action of the bands 26 is moved into the first, the on the side surfaces 14 adjacent sections of the packaging material 4 upwards towards the side surfaces 14 folded. If then in the sequence the general cargo 6 in the sphere of action of the guide plates 24 get, are also on the front surfaces 16 adjacent areas of the packaging material upwards in the direction of the end faces 16 folded, leaving the packaging material 4 then at the bottom 12 and on all sides and faces 14 . 16 is applied.

During the further movement of the piece goods 6 through the fold gate 22 through it finally reaches the bottom of the guide plates 24 as well as the bands 26 where it is squeezed from all sides because of their conical training. This ensures that the packaging material 4 all over and directly to the side and front surfaces 14 . 16 invests.

A further lowering of the piston causes a movement of the piece goods 6 into the mold 28 into it. The protruding portions of the packaging material enter the slots 30 the form 28 , like this from the 4 and 5 is apparent.

Throughout the described movement of the piece goods 6 this comes exclusively with packaging material 4 in touch. A touch through parts of the folding scenery 22 , the form 28 or for the movement of the piece goods 6 competent piston is thereby effectively avoided, so that no contamination of the piece goods 6 due to parts that directly touch the cargo.

5 shows in addition to the 3 and 4 even the vertically extending piston rod 32 of the mentioned piston, which for lowering the piece goods 6 with packaging material 4 through the fold gate 22 through into the mold 28 is responsible.

After the general cargo 6 with the at its side and end faces 14 . 16 attached packaging material completely into the mold 28 was introduced, the form becomes 28 together with the piece goods contained therein 6 from the area below the Faltkulisse 22 moved away, the piston with piston rod 32 in the area below the Faltkulisse 22 remains. To drop the piece goods 6 out of form 28 to avoid, the general cargo is 6 on its underside during the movement from the area of the folding gate 22 and then supported otherwise.

After moving the piece goods 6 with packaging material 4 from the field of folding scenery 22 out, first, the front-side protruding portions of the packaging material 4 towards the top 18 of the piece goods 6 worked. Then, the over the side surfaces 14 out standing sections of the packaging material 4 towards the top 18 folded so that they over the aforementioned, frontally projecting portions of the packaging material 4 to come to rest.

The two in the area of the opposite side surfaces 14 to the top henden sections of the packaging material 4 are sized so that they can be folded towards each other in a manner until they together completely cover the top of the piece goods, wherein the end portions 34 according to 6 of the packaging material get into mutual contact. The two touching end sections 34 are essentially perpendicular to the top 18 of the piece goods 6 aligned.

6 clarifies that the packaged in the manner described so far 6 at the end sections 34 can be taken without leaving areas of packaging material 4 again from the general cargo 6 to solve. This is achieved in particular by the fact that the front-side protruding portions of the packaging material 4 in a sense between the top 18 of the piece goods 6 and in the area of the side surfaces 14 protruding and towards the top 18 folded sections of the packaging material 4 clamped and thus fixed.

After the folding process, a state according to 6 generated (in 6 is the shape 28 not shown for reasons of clarity) is the partially packaged cargo according to 6 together with the form 28 in the area of a sealing device 36 which essentially consists of two sealing jaws 38 and two grippers arranged above it 40 consists. Between the two sealing jaws 38 First, a gap 42 trained, whose size is such that the end sections 34 according to 6 free in the gap 42 can move.

After the end sections 34 in the gap 42 have been moved in, the end sections 34 through the two grippers 40 grabbed and pulled up vertically, causing the packaged cargo to be slightly raised until it is with its top 18 at the bottom of the sealed jaws 38 abuts. This process is a full-scale investment of the packaging material 4 at the top 18 of the piece goods 6 while avoiding disturbing trapped air. During this process, the piece goods 6 from below at its bottom 12 no longer supported, so that the previously described bulge in the region of the underside by the described drawing process 12 results, if the general cargo 6 has a soft, elastic or deformable consistency.

After the full-scale investment of the packaging material 4 at the top 18 of the piece goods 6 was achieved, the two sealing jaws 38 moved toward each other so that the end portions 34 of the packaging material 4 between the sealed jaws 38 be clamped so that then a sealing process can take place. This sealing process becomes as close as possible to the top 18 of the piece goods 6 executed.

The packaging steps described so far are again in omitting all the device components 8th illustrated. Process step A shows the state according to 4 in which the general cargo 6 with the packaging material 4 into the mold 28 was introduced. Process step B shows the state according to 6 in which the end sections 34 abut each other, but still no direct investment of the packaging material 4 at the top 18 of the piece goods is reached.

Step C shows the state after in connection with 7 described sealing process.

According to method step D, the horizontal direction over the end faces 16 protruding portions of the packaging material 4 on the respective associated end faces 16 folded. In step E, finally, from the top 18 horizontally protruding portions of the packaging material 4 down, also in the direction of the two faces 16 folded so that the packaged cargo 6 ultimately, essentially, the contours of the piece goods 6 itself has.
