Definitions

  • the invention relates to a sealing machine for round and non-circular metal packaging.
  • Capping machines for round cylindrical metal packaging are known in many forms, for example from the EP 0 290 874 B1 , Round cylindrical metal packages are commonly referred to as cans. These have a jacket or can body and substantially flat end or cover plates perpendicular to the cylinder axis.
  • Closing machines for metal packaging serve to connect the flat tops and bottoms (lid) of the cans with the can body and crimp.
  • the flat cover plates and the can bodies are each supplied to the capping machine, aligned and then crimped over rollers and springs biased lever and folded.
  • Known capping machines for non-circular metal packaging are capable of closing up to 40 cans per minute in the machine, and perhaps a few more for high-performance machines. This requires a complicated system of levers and springs controlled by closing and forming curves. This complicated system must be redesigned for each specific can shape. Namely, it is required that the metallic rollers run around a square or elliptical edge along a locking piece and press the metal portions folded and flanged around this edge correctly.
  • the cans After the cans have passed through this first mechanism and closed on one side, they are then turned through 180 ° and fed to another machine, in which case the bottom of the cans is also closed from above.
  • the cans are empty during this process.
  • the above methods are used to produce empty cans, in which then later via a special filling mechanism into prepared openings into appropriate content is filled, in particular dangerous goods liquids such as gasoline, oil and more.
  • the object of the invention is in contrast to propose a closing machine for non-circular metal packaging, which is easier to convert.
  • a closing machine for closing metal packaging with a round or non-circular cross-section and with a perpendicular to the cross-section center axis, with feed mechanisms for metal packaging hulls and metal packaging lids, with a plurality of relatively rotatable about a common axis elements whose relative rotation in a movement of a Closing mechanism from and to the implemented common axis of the rotatable elements and is thus used in a movement for precise control of the metal packaging hulls in the lid area.
  • the construction of the sealing machine in a preferred embodiment is characterized by a shaft, on the center line of the central axis of the metal packaging hulls is aligned for closing, by a plurality of coaxially arranged on the rotating and rotatable sleeve members, each with a drive, with each one of Sleeve member is drivable at a controllably variable rotational speed for rotation about the center line of the shaft, by a lever carrier, which rotates with one of the sleeve members, by a lever assembly which rotates with another of the sleeve members and is supported by the lever carrier such that the relative rotational speed the sleeve members to a rotation of the lever assembly to the Axis of the lever carrier leads, and by closing elements on the lever assemblies which are pressed by the movement of the lever assembly against the metal packaging hulls for closing the same with the metal packaging cover plates.
  • the capping machine now works with a shaft on which in particular three sleeve elements (in some cases more, but three are usually optimal) run.
  • Each sleeve element is each preferably equipped on two axially spaced portions with radially encircling teeth.
  • Each sleeve member thus has quasi two integrated gears, which are rotatable together but thus synchronous with each other around the center line of the shaft, but firmly connected.
  • One of these gears is used to drive the sleeve member for its rotational movement about the shaft.
  • a servomotor engages via a corresponding toothed wheel that meshes with this first toothed wheel of the sleeve element.
  • the other of these gears serves as an output and thus the movement of another provided with a meshing gear wheel element.
  • Three sleeve elements are so very precisely drivable with three servomotors so that each rotates at the same or the same speed around the same shaft.
  • the three provided as output gears thus provide relative speeds to each other.
  • the gears may therefore have a different rotational speed, this bypass speed is also controlled.
  • first sleeve member having a first upper gear which is driven by a first servomotor and the sleeve member is set in a precisely known rotational speed.
  • This first sleeve element runs around with, for example, constant speed and provides a similar speed at its second provided for the output gear available.
  • this second sleeve member Concentric within this sleeve member with the first two gears is a second sleeve member, also with a first, upper gear.
  • this second sleeve member is axially slightly longer than the first, outer sleeve member formed.
  • the gearwheel is designed on the outside practically the same as the first one, but can be driven completely independently by it in its speed.
  • the second sleeve element has a relative speed to the first, which can constantly change or change during the rotation. This then applies accordingly for a corresponding second gear on the axially lower side of the sleeve member.
  • This gear is used for hiring a lever that carries the crimping rollers.
  • the crimping rollers themselves are already rotated around the metal packaging by the first sleeve element.
  • the lever is brought closer to or removed from the central center by the second sleeve element and its lower gear, depending on the concrete, desired distance of the crimping roller according to the concrete shape of the square or elliptical packaging and their distance from the center at this specific location edge.
  • the lever is preferably supported by a lever carrier, which is a part of the construction driven by the first sleeve element.
  • the relative speeds of the two sleeve elements are comparatively small; Thus, they only cause a swing back and forth of the lever to the lever carrier.
  • a third, under the first and second sleeve member or between the shaft and the second sleeve member concentrically arranged sleeve member is again longer in the axial direction than the two aforementioned sleeve elements and also has a gear, which in turn is in turn connected to a third servo motor. Again, an output is provided on the axially other side. This provides for a corresponding position of another lever, which carries a post-processing role that is used in the crimping process. The function is the same as that for the crimping rollers.
  • the reworking roller and the first crimping roller are arranged at 90 ° with respect to the central shaft, two further crimping and reworking rollers are opposite the first two rollers by 180 ° and at the same time carry out the crimping processes on the opposite side and their reworking.
  • These can be supplied by the respective second or third sleeve element and thus the second or third synchronous motor or other drive due to their parallel action and the usually symmetrical cross-sectional area of the metal packaging.
  • the rotational speed of the sleeve elements and thus of the gears can be adjusted very finely and alternately by a belt drive and the servomotors running on the belt drive,
  • the sleeve elements and thus the output gears move immediately different, so that the lever assembly performs a different process around the metal packaging, which can be relatively easily foreseen, taken into account and adjusted.
  • a change in the can shape can be done practically alone by switching within the software, so by choosing a different program.
  • the closing part must be replaced, but this is relatively simple and allows a change and a conversion of the system within an hour or two. In addition, a conversion to much more diverse doses is possible. Even more frequent changes with smaller total quantities can be made so profitable, if the appropriate locking parts are kept.
  • the use of the machine is thus much more versatile. It is characterized by a high degree of flexibility.
  • a change in the can diameter or the can format is achieved by a simple, for example menu guided input of dimensions or other data by the user on the control panel, with only a few format change parts are needed.
  • Form curves and Verschwekurven together with Abtastrollen as in the prior art are no longer needed.
  • the number of revolutions for the closing ⁇ en a particular metal packaging can be changed almost arbitrarily.
  • a sequence correction in partial areas on the circumference of the box can be done.
  • the closing machine shown in FIG. 1 serves to close non-round metal packaging. It can be seen right below a can body 1. This can body can be elliptical or square, which is not visible in the side view. Above the can body or metal packaging hull 1 there is a metal packaging cover plate 2. In the illustrated situation, these two elements have already been supplied from the side to the closing machine. You are on a mechanism with a device 3 for feeding and aligning the metal packaging. This has - indicated by an arrow - the metal packaging hull 1 and the metal packaging cover plate 2 already placed on each other and both lifted directly below the other elements. All of this is done at high speed with one metal wrap after the other.
  • the closing machine itself has a basic structure or holder 4. This can be seen in FIG. 1, in particular, by a vertical stand which carries the various other movable and immovable parts.
  • An essential part of the closing machine in this embodiment is a shaft 5.
  • this shaft 5 is vertical, fixed and non-rotating. Therefore, the metal packaging supplying and aligning apparatus 3 has already aligned the metal packaging body 1 and the metal packaging lid sheet 2 on the shaft so that the center axis of the metal packaging body 1, the metal packaging lid sheet 2 and the shaft 5 all fall on each other.
  • three sleeve elements 10, 20 and 30 are arranged concentrically. These three sleeve elements can rotate about the shaft 5, but they are not axially displaceable to it. There may be embodiments in which a rotatability of the shaft 5 and an axial displaceability of the sleeve members 10, 20, 30 come into consideration, but usually this is not required and is therefore not provided in the illustrated embodiment.
  • a drive 11, 21, 31 is provided in each case. Shown in the drawing is only a first drive 11, in the form of a servo motor.
  • This servomotor drives via a belt drive above above the holder 4 of the capping machine to a drive shaft which is vertical and thus parallel to the shaft 5 and ends in particular below in a gear.
  • This gear meshes with a gear 12.
  • This gear 12 is a part of the sleeve member 10, which can be seen as the utmost of the three sleeve members 10, 20, 30.
  • the three sleeve members 10, 20, 30 have a different axial length, so that they can be arranged coaxially with each other about the shaft 5, but each extending axially further and thus accessible from the outside.
  • the speed with which the three sleeve elements 10, 20, 30 rotate about the shaft 5 is controlled differently, since they are driven by different drives 11, 21, 31. However, the speeds are not very different, so that the relative speed of the sleeve elements can be finely adjusted. Overall, however, the speed causes the further recognizable and hereinafter described elements 15, 25, 26, 35 and 36 are in a circle around the area in which the metal packaging cover plate 2 is to be crimped onto the metal packaging body 1.
  • the first, outer sleeve member 10 has on its lower, the metal packaging cover plate 2 and the metal packaging body 1 closer side of a gear 13 for the output, with a lever carrier 15 is supported.
  • the second, middle sleeve member 20 carries a gear 23 for the output. With this gear, a lever assembly 25 is rotated. This lever assembly 25 is seated on the lever carrier 15. Now turns the gear 23 for the output faster than the gear 13 for the output of the first, outer sleeve member, this leads to the fact that the lever assembly 25 is rotated about the lever carrier 15 more or less slightly becomes.
  • the third, inner sleeve member 30 operates with a gear 33 for its output, which on the other side a lever assembly 35 and a Nachbearbeitungsrolle 36 also delivers.
  • Figures 3 to 8 show successively seen from above how the crimping roller 26 and the Nachbearbeitungsrolle 36 behave relative to the lever carrier 15.
  • lever carrier 15 circles around the approximately rectangular metal packaging body 1 in a circular shape. It should be noted that here several lever carrier 15 is provided, as well as several roles must be delivered in each case.
  • the levers 15 each carry the lever assemblies 25 and 35, respectively, with the crimping and reworking rollers 26, 36. Therefore, these rollers 26, 36 essentially orbit the metal packaging body 1 in the same shape, but upon closer inspection, change their distance from the central axis of the shaft 5 and the metal packaging hull 1 and fit so exactly the shape of the metal packaging hull 1. It is stated in each case that, of course, an approximation and then also a removal from the metal packaging body must be provided.
