Definitions

  • the invention relates to a device for wrapping piece or packaged goods with an at least approximately hood-shaped elastic film section, which is folded by shirring and stretched and then pulled over the piece or packaged goods, wherein the shirred film section by means of a piece along the piece. stretched over the piece or packaged goods, and wherein the coating device has four movable in the plane perpendicular to the coating direction clamping fingers, each having a substantially extending in this plane bow-shaped clamping element and an attached arcuate, and in the Essentially in Studentsziehraum have extending support member to record the shirred film section in each of the corners of the piece or packaged goods to be wrapped corresponding areas and then over the piece and packaged goods over.
  • the film section which is usually one closed at one end Hood acts by shirring on the overdrawing device itself.
  • the overdrawing device has for this purpose apart movable chuck corners, wherein preferably in the corner regions of the overdrawing each a pair of a Rafrolle and an opposite counter-roller is provided, which are rotatably mounted about its horizontal axis.
  • the film section is clamped between the counter-rollers and the gathering rollers and is creased by the driven gathering rollers.
  • the clamping corners are moved apart, so that a tension is exerted on the film section and so the film section is stretched so that it can then be pulled over the piece or packaged goods.
  • the coating device is lowered along the piece or packaged goods, wherein the film portion rests against the top of the piece or packaged goods and is thereby held.
  • the wrinkles which form the periphery of the film section, increasingly withdrawn, so that when the coating device reaches its lowest position, the entire film section no longer has wrinkles and surrounds the piece or packaged goods and possibly the pallet underneath.
  • a separate gathering device and a separate coating device are provided.
  • the film section is gathered by a gathering device and then taken over by a separately movable coating device, which then covers it over the piece or packaged goods.
  • the coating device has in the corner regions opposite to the coating direction pointing rod-shaped holding elements, which take over the shirred film section of the shirring.
  • the film section is then stretched by moving apart of the holding elements and moves the overdrawing device for coating along the piece or packaged goods.
  • a disadvantage proves that when stretching the tube section this is not sufficiently fixed, so that the film section can not be sufficiently stretched, since it slips off some of the holding elements.
  • the object of the invention is to improve a device according to the preamble to the extent that the head portion of the film portion can be stretched more.
  • This object is achieved in that at least on a clamping finger from the outside at least in the region of the piece or packaged goods shortly before reaching the stall position furthest over the piece or packaged over-pullable fold, especially in the adjacent to this fold unfolded area of Film section, can be applied to the film section, baking-like and the corner region of the clamping finger at least partially embracing fixing device for clamping fixing the corresponding portion of the film section on the clamping fingers during stretching is provided and to increase the clamping effect at least the surface of the fixing device can be brought into contact with an adhesion improving Surface, wherein in order to avoid damage to the film section, the Surface has a soft coating, in particular sponge rubber or the surface alternately raised and recessed areas.
  • the fixing device is applied before the stretching from the outside at least in the region of the piece or packaged goods just before reaching the stall position furthest, over the piece or packaged over-folding fold, especially in the adjacent to this fold unfolded area, to the film section, so the film section is fixed in a clamping manner between the fixing device and the clamping finger. As a result, the film section can be stretched more in the head area.
  • the fixing device is only then released again after the head region of the film section rests on the piece or packaged goods during coating. Then the coating device is moved along the piece or packaged goods, so that the folds can be deducted from the coating device and the piece or packaged goods is surrounded by the film section.
  • the fixing devices can preferably be in the area of the fold not yet pulled off the clamping fingers and finally over the piece or packaged goods be applied again from the outside to the film section.
  • the film section can additionally be tightened and stretched in the coating direction in the almost completely over-drawn state.
  • a fixing device is provided in each case for two diagonally opposite clamping fingers. But it is also quite possible that a fixing device is arranged on each clamping finger.
  • the fixing device may have a design which is substantially adapted to the outer contour of the clamping finger in the contact region of the clamping finger and the fixing device.
  • the surface of the fixing device which can be brought into contact with the film section may be arc-shaped.
  • the fixing device may be movable in the plane perpendicular to the coating direction.
  • guide slide may be provided which allow movement along two adjacent side of the piece or packaged goods.
  • the fixing devices are only translationally movable or a combination of the different methods of operation is provided.
  • the fixing device can be moved by means of a rotatably arranged adjusting lever in the direction of the corresponding clamping finger. It is advisable if the fixing device is articulated on the adjusting lever, so that the fixing device optimally adapts to the outer contour of the clamping finger. It makes sense, if the Fixing device is rotatable only to a small extent with respect to the adjusting lever, to prevent that upon movement of the fixing device in the direction of the clamping finger, the fixing device is rotated and does not come into contact with the correspondingly provided surface with the film section.
  • the adjusting lever can be hydraulically or pneumatically actuated, for example. Other drives, such. As electrical, are possible.
  • the surface may have an adhesion-improving coating.
  • the coating device is intended only for stretching and coating, a separate gathering device is provided for independent gathering.
  • the subsequent stretching of the film section and coating on the piece or packaged goods is then carried out by the shirring separately and separately from the shirring along the piece or packaged movable overdrawing device. This makes it possible that by means of the gathering device already another film section can be gathered while the previous film section is still pulled over the piece or packaged goods.
  • the surface of the fixing device which can be brought into contact with the film section essentially corresponds to the minimum contact surface required for avoiding damage to the film section during stretching in coordination with the technical features and properties of the film section and the stretching to be achieved.
  • technical features and properties are understood, for example, the thickness, elasticity or stretchability of the film section, which have an influence on the minimum required contact surface in order to avoid damage.
  • shape, the size or the nature of the piece or packaged goods affect the size of the minimum required contact surface.
  • the invention also relates to a method for wrapping a piece or packaged goods with an at least approximately dome-shaped elastic film section, which is crinkled by shirring and stretched and then pulled over the piece or packaged, the shirred film section by means of a along the Stretched or packaged movable overdrawing device is stretched and over the piece or packaged goods, and wherein the coating device has four movable in the plane perpendicular to the coating direction clamping fingers, each having a substantially extending in this plane bow-shaped clamping element and an attached thereto arcuate, as well as pointing substantially extending in the direction of extending support member to the shirred film section in each of the corners of the piece or packaged goods to be enveloped areas to pick up and then over the piece and packaged goods over.
  • a disadvantage of known methods proves that the film section in the head area, d. H. in which the piece or packaged goods just before reaching the stall position furthest located area, can not be sufficiently stretched before coating, since the film section can be solved in this area during stretching of the clamping fingers.
  • the object of the invention is therefore to improve a method in that the head portion of the film portion can be stretched more.
  • This object is achieved in that at least on a clamping finger from the outside at least in the region of the piece or packaged goods shortly before reaching the stall position furthest over the piece or packaged over-pullable fold, especially in the adjacent to this fold unfolded area of Foil section, can be applied to the film section, baking-like and the corner region of the clamping finger at least partially embracing fixing device for clamping fixing the corresponding portion of the film section on the clamping fingers during stretching is provided, wherein at least one fixing before stretching the film section for fixing in the region of the corresponding clamping finger applied to the film section and after contact of the approximately hood-shaped film section with the piece or packaged goods is removed from the film section, wherein to avoid damage to the film section with the Folienabschn itt contactable surface of the fixing a soft Coating such. As sponge rubber, or other coatings. Due to the clamping fixation of the film section is secured when stretching on the clamping fingers from unintentional partial loosening during stretching, so that high degrees of stretch can be realized.
  • At least one fixing device can be applied again after removal of the folds shortly before removal of the film section from the access area of the fixing device for fixing the film section to this in the region of the corresponding clamping finger.
  • the fixing device By reapplying the fixing device shortly before completion of the coating process, the film section can be tightened in the coating direction and - if desired - also stretched, so that thereby high vertical degrees of stretch can be achieved.
  • the fixing devices are again removed from the film section and the coating device is preferably returned to its original position.
  • a method for wrapping piece or packaged goods with an at least approximately hood-shaped elastic film section which is folded by shirring and stretched and then pulled over the piece or packaged goods, wherein the shirred film section by means of a piece along the piece.
  • stretched and packaged movable overdrawing device and is pulled over the piece or packaged goods and wherein the overdrawing device may have four movable in the plane perpendicular to the coating direction clamping fingers, each having a substantially extending in this plane bow-shaped clamping element and an attached thereto arcuate, and pointing support element extending substantially in the direction of coating, to accommodate the shirred film section in each corresponding to the corners of the piece or packaged goods to be wrapped and then over-coat the piece and packaged goods.
  • the film section is gathered zieharonikaartig in the shirring process.
  • the folds should be oriented obliquely downwards towards the packaged item or packaged goods and pointing outwards. Only this uniform alignment of the folds ensures a later easy removal of the film section, since then fold by fold can be deducted from the overdrawing device.
  • the fold to be pulled off the adjacent fold which is to be peeled off in a next step is at least partially, if not completely, covered and thus pinched and held.
  • This circumstance can lead to damage of the film section, as by pulling out this fold high tensions occur in the film section and thus holes can be pulled into the film section.
  • This risk is particularly great in film sections of small thickness, since then pull the film section easier when pulling out, or piece or packaged goods high altitude, as a greater length of film section gathered and therefore a greater number of wrinkles must be formed.
  • the shirred film section is stretched over the piece or pack good in a first step by a first higher amount and in a second step the stretch of the film section during the coating process the shirred film section over the piece or packaged goods to a lesser amount, but still allows the coating is reduced.
  • the film section is first stretched in a first step by an amount that is significantly above the stretch, as has been done in previously conventional methods.
  • This stretching has been kept as low as possible on a regular basis and limited to the required for a proper implementation of the process minimum extension.
  • the film section is stretched by such a smaller amount that during coating there is an all-round distance between each side of the piece or packaged goods and the film section of 3 to 5 cm.
  • the film portion is first stretched in a first step by a greater amount, so that in this more stretched state, an all-round distance between each side of the piece or packaged goods and stretched by the greater amount of film section of about 6 to 10 cm established. Stronger extensions are possible.
  • the clamping fingers By subsequently reducing the stretch of the film portion in a second step during the coating process - by moving respective components of the coating device, usually the clamping fingers - the tension in the folds of the gathered film portion is reduced, whereby the wrinkles, especially in a non-desired folding orientation, not more so strongly clamped by an adjacent fold and are held, so that the film section without damage can be easily removed during the coating process.
  • the reduction in tension may result from an at least partially delayed reset with a corresponding resulting, still beyond the minimum extent and / or at a successful default, which is less than the release occurring in the absence of all holding forces free reset, from the time offset with the one Tension is restored, resulting.
  • the higher amount of stretch is outside the tolerance range of the extension by the smaller amount and is clearly to be regarded as excessive compared to the extension by the smaller amount.
  • the measure of the smaller amount of stretch which corresponds to the minimum stretch, depends not only on the geometry of piece or packaged goods. Other parameters, such. As the dimensions of the located within the film section system parts of the stall, have an influence on the degree of the lesser amount of stretch.
  • the reduction of the stretch to the smaller amount can be done with the first contact of the film section with the top of the piece or packaged goods or only at a later time during the coating process.
  • the complete coating process is at least for the most part completed before all recovery operations have been completed and the film section has again reached the extent afforded by the stretch to a lesser extent.
  • the reduction of the stretch can be done in the first third of the coating process.
  • the coating process begins with the contact of the film section with the top of the piece or packaged goods.
  • the reduction of the stretch at a distance of 5 to 20 cm from the top of the piece or packaged goods, preferably at a distance of 10 cm from the top of the piece or packaged goods, take place.
  • the film section stretched by a higher amount in the first step is fixed at the beginning of the coating process by means of at least one fixing device, and the fixing device is removed again with a reduction of the stretch in a second step to a smaller amount from the film section.
  • the film section stretched by the higher amount in the first step is first fixed.
  • the film section sets only on the top side of the piece or packaged goods, while the sides of the piece or packaged goods are not in contact with the film section.
