Definitions
- the invention relates to an arrangement for forming a belt loop between a unwound drivable tape supply roll and a tape feed device.
- the assembly is used in a method of manufacturing tear-open covers, comprising forming a plurality of parallel rows of metal lid rings, progressively conveying the lid members to a plurality of processing stations, and feeding a film strip from a supply roll to the lid rings and punching Film sections and the application and heat sealing of the film sections on the cover rings in a punching and sealing processing station takes place, wherein in the film strip by means of a hollow cylinder of the arrangement a film strap loop is formed, which comes to lie between the film roll and the collection of the film strip in the punching and sealing processing station , In this case, a movement of the hollow cylinder is limited by a cross bar.
- the invention relates to a device for the production of tear-open lids with an arrangement according to the invention.
- lids for can or box-like packaging on the top of the package permanently attached metal lid, which form a removal opening, which is closed until the first use of the packaging content with a heat-seal applied, tear-off film, in particular metal foil.
- An additional, arranged over the metal lid plastic lid makes the packaging during the period of use for their contents closed again.
- Devices for producing such metal lid are described below with reference to the FIG. 5 explained in more detail.
- the FIGS. 6 to 12 serve to explain manufacturing steps in the production of such covers.
- the tear-off film is withdrawn during manufacture as a broad film web from a tape supply roll and introduced into the punching and sealing stations or guided over the lid parts.
- dancer roller systems are used, which can, however, at high production cadences problems in the stepwise film transport, especially in thin film strips.
- Belt loops of conventional type are generated by the control of the drive of the unwinding tape supply roll and regulated, for example, by means of a distance sensor which measures the distance of the loop from the stationary sensor. For strongly changing pull-in lengths at high belt speeds, this is costly in terms of drive or results in unsatisfactory results.
- DE-A 40 02 194 it is proposed to form a belt loop by means of an air flow.
- U.S. 4,842,681 discloses a device in which a strip of material is unwound from a supply roll and processed in a further plant. Between the supply roll and the system, the strip of material is guided with a loop, which results from a cylinder acting on the strip in order to reduce or increase the extent of the loop.
- DE 43 27 670 A1 discloses a device in which a film is unwound from a supply reel and cut in a cutting machine, with a loop of the film strip being formed therebetween.
- a rod is placed on the film strip, which is displaceable by means of suitable bearings vertically on rails in order to increase the size of the loop or to reduce.
- the vertical path of the rod is monitored by means of sensors, whereby an upper and a lower displacement limit of the rod are defined.
- the invention is based on the object to provide an arrangement with which a belt loop can be provided in a simple manner, which works safely even at high production cadences with gradual tape transport and in a variety of film materials.
- the cross bar is arranged vertically displaceable in each vertical slot guide in the side walls in order to restrict the freedom of movement of the hollow cylinder in the vertical direction.
- the diameter and also the material of the hollow cylinder can be chosen differently. So the diameter can be chosen eg 20 cm or bigger. As a material in particular plastic comes into question.
- the invention is further based on the object to provide a method and an apparatus for the production of tear-open, in which the advantageous arrangement for obtaining the belt loop is used. This is achieved by the method according to claim 8 or the device according to claim 11.
- the film strip is preferably viewed horizontally and in plan view with its longitudinal direction substantially perpendicular to the conveying direction of the cover parts fed into the punching and sealing processing station with partly uneven step lengths.
- FIGS. 1 to 4 show an embodiment of an inventive arrangement 1. This is provided and configured to form a belt loop 7 in a band 6.
- the belt 6 is driven unwound from a supply roll 2 and then passes into the assembly 1.
- the belt is conveyed by a feeder 4, which belongs to a device in which the belt is used or processed.
- a feeder 4 belongs to a device in which the belt is used or processed.
- the unwinding of the tape supply roll is usually carried out at a uniform speed or can be adjusted only relatively slowly via the drive 19 to rapid changes in speed of the intake device 4.
- the drawing-in device 4 can bring about a gradual introduction of the strip with changing catchment lengths.
- the arrangement 1 has the purpose on the belt loop 7 to compensate for the Einzugsschwankache in speed and / or Einzugs Mariner by the loop forms an easily retractable strip material supply. This is known in principle.
- the drive 19 can be done by the control of the device with the intake device 4 in order to adapt the tape processing to the tape needs. It can also be a sensor 19 ', in particular in the form of a distance sensor, be provided, whereby the drive 19 can respond to the increase in length or length decrease of the loop.
- the sensor signals can be delivered to the controller of the device and processed there for the control of the drive 19 or they can be delivered to a directly associated with the drive control to supplement the control signals from the device.
- the arrangement 1 has two side walls 8 and 9, which consist for example of plastic or metal.
- the diameter of the hollow cylinder can be chosen differently.
- the hollow cylinder may for example consist of plastic, in particular of polymethyl methacrylate (abbreviated PMMA, colloquially acrylic glass). It can also be a material with a higher specific weight can be selected to achieve a greater bias, such as aluminum.
- PMMA polymethyl methacrylate
- the hollow cylinder preferably has the illustrated circular cross section, but could also have an oval or polygonal cross section.
- the hollow cylinder is guided substantially flush with its end faces between the side walls, so that it can move freely between the side walls without tilting relative to the side walls.
- the hollow cylinder is free to a limited extent in its movement, so that it can move freely in the direction of tape travel and perpendicular thereto by a predetermined amount. This amount depends on the diameter and depends on the processing.
- the restriction of movement can be limited by any means acting on the hollow cylinder.
- a cross bar 11 which is arranged horizontally lying between the side walls and extends through the hollow cylinder therethrough.
- the crossbar 11 may be arranged fixed in the side walls or preferably guided vertically displaceable therein.
- the illustrated vertical slot guides 12, 12 ' may be provided.
- the hollow cylinder 10 is shown in its vertical lowermost position. He lies with his inner wall on the crossbar 11, which in turn is located at the bottom of the slot guides. Now withdraws the collection device 4 more tape off, is handled as driven by the supply roll, so the belt loop shortens, causing the hollow cylinder is deflected from the illustrated bottom layer. He is free in his movement between the side walls. It has been shown that by such a freely movable hollow cylinder, which thus within the free mobility only with its weight (which is adaptable by diameter selection and / or choice of material of the hollow cylinder) rests on the tape and forms the deflection and causes the bias of the tape , even very thin and light foil bands are very good as a loop handle.
- the free mobility of the hollow cylinder through the band is limited by the crossbar 11. If the path length of the free mobility is used up (which results here through the inner diameter of the hollow cylinder), contacted in this embodiment, the hollow cylinder first, the cross bar 11, whereby its free mobility is used up and is also reduced laterally. This position is in FIG. 3 shown. If more ribbon is drawn in than unwound, the hollow cylinder pulls the cross bar upwards. This is in FIG. 4 clearly visible.
- the arrangement has an upper inlet-side band deflection 14 and an upper outlet-side band deflection 15.
- the tape deflections are arranged at the top of the side walls.
- the deflections may be rollers that rotate with the tape. But it can also be provided non-rotating deflections.
- adjustable lateral boundaries are provided for the band so that it runs in a defined position over the band deflections 14, 15.
- axially displaceable and fixable thrust washers 14 'and 14 "on the band deflection 14 and 15' and 15" on the band deflection 15 are provided on the respective deflection 14 and 15, respectively. These thrust washers, after loosening their attachment, are adjusted in their spacing to the width of the belt and then re-attached to form lateral boundaries for the belt.
- the tape can on the inlet side via a deflection 16 (FIG. FIG. 3 ) are guided, so that the tape from the supply roll 2 under the guide roller 16 and the hollow cylinder 10 extends.
- the arrangement 1 is preferably fastened by adjustable fastening means 17, 18 to the carriers 5 and 3 for the supply roll 2.
- the adjustability makes it possible to adjust the spacing of the arrangement 1 in the horizontal direction from the carriers 5, 3.
- the preferred use of the arrangement in the production of tear-open lids will now be explained.
- the tape present on the supply roll 2 is the tear-open film material from which the tear-open film is punched out for each cover.
- FIG. 5 shows a schematic side view of a known device 21, which has a plurality of processing stations 23 to 28 and a further station 29 on a machine frame 22.
- a conveyor for the lid parts is according to a preferred embodiment, a linear conveyor, as they are made WO2006 / 042426 is known.
- This linear conveyor is designed for conveying lid-shaped objects of the type described below by means of a toothed belt and is suitable for a very rapid promotion and lid production.
- opposite and synchronously moving timing belt opposite receptacles for the cover parts are provided.
- the conveyor device is used for cyclically conveying the lid parts or covers to the individual processing stations, as will be explained below.
- conveying device conveys the lid parts or the finished lid with tear-off in the conveying direction, which is indicated by the arrow C, from the beginning of the device at the stack 31 to the end of the device where the lid via slides into the trays 36 or 37 arrive. From the stack 31 lid parts are stacked in a known manner and get into the conveyor.
- the conveyor shown has a different construction than the preferred linear conveyor according to WO2006 / 042426 and will be briefly explained here.
- FIG. 6 shows stacked metal lid blanks 120 as an example of lid parts as they are in the stack 31.
- These blanks 120 are eg round metal discs of eg 11 cm diameter. Of course, other basic shapes, such as square or rectangular discs and other diameters are readily possible.
- the blanks 120 are already in a processing machine, not shown, at its edge as in FIG. 5 shown preformed. In the FIG. 6 and the following figures, only one sector of the entire disk is shown to simplify the drawings.
- an opening 129 in the disc which in FIG. 7 can be seen, in which the edge of the opening is denoted by 121 and the punched round disc with 127. This disc is discharged as waste.
- the punching processing station 23 is - as is the case with the other stations - driven by a drive 115.
- the edge 121 is pulled down, whereby the in FIG. 8 shown course 122 of the edge is achieved.
- the annular blank blanks 120 now pass into the punching and processing station 25, in which the tear film 125 is placed over the opening of the lid 120 and fixed there by heat sealing, resulting in the FIGS. 9 and 10 is apparent.
- the tearing film 125 is preferably a laminate film or is an aluminum foil and is provided in known manner on its underside with a plastic layer.
- the required foil blank 125 is punched in the station 25 from a wide film web and placed over the central recess of the annular disc and the film is pressed by heat sealing at the edge of the circular recess of the part 120 under heat, so that the film 125 with the metal lid 120 is sealed by melting and subsequent cooling of the plastic layer.
- This is known and will not be explained here.
- the tear-open film in the punching and processing station 25 is only pre-sealed and subsequently sealed in a further heat-sealing station.
- a cooling processing station 27 may be provided for cooling.
- the film 125 can be embossed 124 (FIG. FIG. 11 ), and the edge 122 is further crimped to the finished edge 123.
- a test station 29 the now finished covers are subjected to a test, which usually includes the below-explained in more detail density test for the applied on the lid liner 25. If the film is tightly attached to the rest of the metal lid, the lid enters the receptacle for the finished lid. If a leak is detected, the lid passes over the other slide shown in the waste container.
- the lid parts or lids can be conveyed at high speeds of, for example, 200 objects per minute and with reproducible partial steps between the stations. It also results in a flexible concept for a large format range of the items or lid, which may range from 50 to 200 mm in diameter for round lids and also include various rectangular formats for example for the usual fish cans can.
- the conveyor is also designed as a compact module especially for multi-lane construction. In combination with such a production of high cadence lids, the arrangement for forming the belt loop can be used particularly advantageously. However, it can also be used in other devices in which a belt loop must be created.
- an arrangement is provided in which a hollow cylinder loosely rests with limited freedom of movement to form the belt loop on the tape.
- Such an arrangement is preferably provided in the manufacture of tear-open lids, in which a foil strip is unwound from a supply roll and fed to a punching and sealing station.
