Definitions

• the invention relates to a device for forming sleeve-like foil envelopes from a continuous flat strip of a sleeve-like foil material, comprising supply means for supplying the continuous flat strip of sleeve-like foil material, cutting means for making a cut in this strip of sleeve-like foil material over the full width thereof so as to obtain the individual sleeve-like foil envelopes, as well as discharge means for discharging the individual sleeve-like foil envelopes from the device.
• Such a device is for example disclosed in European patent publication No. 0 109 105.
• individual sleeve-like foil envelopes are realised in one cutting motion, which individual, flat, sleeve-like foil envelopes must subsequently be opened and be placed around an object, such as a bottle or other container, with a slight oversize.
• the foil material that is used is made of a so-called “shrink material", which will shrink under the influence of heat being supplied thereto and conform tightly to the shape of the bottle or other container around which the foil envelope has been placed.
• the foil envelope has already been produced in the form of a continuous strip wound on a roll, which needs to be cut to the correct length by means of a device as referred to in the introduction.
• the cutting means are driven in dependence on the length, in such a manner that they cut the strip of sleeve-like foil material to the correct length, after which the individual sleeve-like foil envelope thus formed is discharged from the device and opened, to be subsequently placed around the container in a manner which is known per se.
• a drawback of the device that is currently known is that it is only suitable for use with thick or stiff foil materials in order to thus realise a high processing speed. When thinner or more flexible foil materials are used, the processing speed must be reduced in order to prevent undesirable jamming of the device.
• the object of the invention is to obviate the above drawbacks and to provide a device as referred to in the introduction, in which large numbers of foil envelopes of varying length and varying types of material can-be produced at a high processing speed.
• the device is to that end characterised in that the device comprises means arranged for imparting a rotary motion during operation to the sleeve-like envelope to be discharged from the device.
• the rotation means comprise at least one rotatably drivable roller, which can be brought into abutment with the sleeve-like foil envelope to be discharged.
• the rotatable driving roller is disposed at an angle relative to the supplying direction of the flat strip of sleeve-like foil material, so that in addition to a rotation component also a translation component can be imparted to the foil envelope to be discharged. This latter aspect is necessary for discharging the foil envelope from the device and placing it round a container.
• the angle in question effectively ranges between 30° and 80° so as to impose a rotation as well as a translation to the foil envelope to be discharged and prevent the foil envelope from blocking up and causing the device to jam.
• the rotation means comprise a nozzle that can be directed at the sleeve-like foil envelope to be discharged from the device for delivering a medium under pressure, in particular compressed air. In this way, too, a rotary motion can be imparted to the foil envelope to be discharged in an effective and controllable manner.
• Figure 1 shows an embodiment of a device according to the invention
• Figures 2-4 shows various embodiments of a device according to the invention.
• numeral 10 indicates a device according to the invention.
• the device 10 comprises supply means or moving means 12 made up of two drivable rollers, between which a continuous strip of foil material 1 can be carried.
• the continuous strip of foil material 1 is wound on a supply reel 11 and is introduced into the device via a tensioning mechanism 13.
• the tensioning mechanism 13 has an arm 13a, which is pivotally connected to the device.
• the pivot arm 13a comprises several rollers 13b, over which the continuous strip of sleeve-like foil material 1 is passed.
• the strip of sleeve-like foil material 1 is also passed over additional, fixedly disposed rollers 13c.
• the supply means 12 carry the continuous strip of sleeve-like material 1 past cutting means 14 for cutting the foil material through at predetermined intervals so as to obtain individual sleeve-like foil envelopes 1'.
• the cutting means may be configured in various ways, which may be considered to be known to the skilled person.
• Disposed at the location of the cutting means 14 and the discharge side of the device 10 is a spreading element 19, which functions to open the obtained individual, flat, sleeve-like foil envelopes 1' for the purpose of placing the opened, sleeve-like foil envelope around a container.
• the spreading element 19 is enlarged at least in the plane perpendicular to the plane of the flat, continuous strip of foil material 1.
• the individual, flat, sleeve-like foil envelopes ... - 1'.., - V 0 - 1 ' +1 - ... are opened, so that they can be easily placed around a container ... - 2 A - 2 0 - 2 +1 - ....
• the containers ... - 2., - 2 0 - 2 +1 - ... are moved by conveying means 21 , which are considered to be known per se, which conveying means 21 are provided with a carrier 21a, on which several containers (bottles, jars or cans) are present, which containers are carried to the device 10.
• Each individual, flat, sleeve-like foil envelope ... - 1 V, - V 0 - 1 ' + i - •• ⁇ is opened by the spreading element 19 and cut loose from the strip of foil material 1 by the cutting means 14, after which the sleeve-like foil envelope thus opened can be easily placed over a waiting container ... - 2 ⁇ - 2 0 - 2 +1 - ....
• discharge means 20a-20b may be provided, which are mounted in the device at the location of the spreading element 19.
• Said discharge means may comprise one or more drivable rollers 20a, which are supported on the stationary rollers 20b and which discharge the sleeve- like foil material 1 ' present therebetween from the device 10 at an accelerated rate, with the individual, opened foil envelope ... - 1 '.., - 1 ' 0 - 1 ' +1 - ... slipping over a container ... - 2 ⁇ - 2 0 - 2 +1 - ..., as it were.
• the foil envelope To place a sleeve-like foil envelope V around a container 2, the foil envelope must be placed in an open position by the spreading element 19 to enable easy and quick placement thereof around the container 2. Given the fact that increasingly thin and flexible foil materials are currently being used, as well as the fact that such devices are operated at high processing speeds, it has been found that the opened sleeve-like foil envelope, upon leaving the device 10 or the spreading element 19, tends to return to its flat shape before it has been placed around the container 2. This phenomenon results in the device 10 jamming and stopping, which is undesirable.
• means which impart a rotary motion on the sleeve-like foil envelope ... - 1 V, - V 0 - 1 ' +1 - ... to be discharged from the device 10.
• the sleeve-like foil envelope thus discharged will make a rotary motion before slipping over or being placed around the container ... - 2 ⁇ - 2 0 - 2 +1 - ... in question.
• FIG. 2 Such an embodiment of the device according to the invention is shown in Figure 2, in which the rotation means are indicated by reference numeral 20'.
• said rotation means 20' are incorporated in the device as a supplement to the discharge means 20a-20b.
• the rotation means 20' comprise at least one rotatably drivable roller or driving wheel 20a', which can be brought into abutment with the sleeve-like foil envelope ... - 1 1 ., - 1' 0 - T +1 - ... to be discharged.
• Said driving roller 20a' thus imparts a rotary motion to the foil envelope in question, whilst the discharge means 20a-20b, in synchronisation with the rotary motion of the foil envelope, discharge the foil envelope in question in the direction of the container 2 in question via a translating motion of the spreading element 19.
• the rotation means 20' are incorporated in the device 10 by way of supplement to the discharge means 20a-20b, the embodiment shown in Figure 3 only makes use of the rotation means 20', which in this embodiment also function as discharge means for discharging an individually formed sleeve-like foil envelope ... - T -1 - T 0 - T +1 - ... from the device and from the spreading element 19. It is essential in this regard that the rotation means 20' impart a rotary motion as well as a translating motion to the sleeve-like foil envelope in question, making it necessary to dispose the rotatable driving roller 20a 1 at an angle relative to the supplying direction of the flat strip of sleeve-like foil material.
• FIG. 4 shows yet another embodiment of the rotation means 20', in this case comprising at least one nozzle 2Od' which can be directed, whether or not at an angle, at the sleeve-like foil envelope ... - T -1 - T 0 - T +1 - ... to be discharged.
• the nozzle 2Od' is connected, via a supply pipe 2Oe', to a source for a medium under pressure, for example a compressor or a pump. Via the nozzle 2Od' a jet of a medium under pressure, in particular compressed air, is directed at the sleeve-like foil envelope to be discharged.
• This embodiment too, imparts a rotary motion as well as a translating motion to the sleeve-like foil envelope to be discharged so as to thus place a rotating sleeve-like foil envelope around the container 2 in question.
