Definitions

  • the invention relates to a method for positioning a can frame, which is produced by rolling a flat sheet metal blank into a cylinder and longitudinal seam welding the same, or the like at a predetermined point on its outer circumference with a tab. Provide a head start and then further processed.
  • the invention relates to a device for positioning a can frame of the aforementioned type.
  • Such a can frame can be torn open with the aid of the tab being gripped and rolled up with a key.
  • the can frame further has a pair of circumferential scratches which extend around the longitudinal axis of the can frame and laterally delimit a tear strip.
  • the first possibility is (DE-PS 1 017 042) to punch out the flap in one piece together with the flat sheet metal blank in the initial state, and at the same time, with the circumferential scoring, a starting scoring connecting it to one another in the region of one of the two longitudinal edges of the sheet metal blank is punched into it becomes.
  • the sheet metal blank is rolled into a cylinder before its two longitudinal edges are welded, so that the two longitudinal edges overlap one another.
  • After the longitudinal seam welding, such a can body produces a complete can in which the two end faces of the can body are flanged with a Cover or bottom are closed.
  • the key which is put on the tab to open the can, has a slit and is unrolled at the closest edge of the flange.
  • the second option (CH-PS 669 365) is to weld the tab as a separate sheet metal part in the area of the tear strip onto the outer circumference of the can frame only after the longitudinal seam welding, directly on the longitudinal seam or at a distance from it.
  • a known variant of the aforementioned second possibility consists in welding the tab to the tear strip of the flat sheet metal blank and only then rolling the sheet metal blank into a cylinder and welding it in the longitudinal direction.
  • This variant is described in DE-PS 35 15 812, which, moreover, in FIGS. 2a-2d also very clearly shows various embodiments of the tab before welding.
  • the tabs is a welding machine, such as is known for example from the applicant's DE-PS 35 13 703, or a device for spot welding coated sheet metal parts, in particular for welding tabs to tear-open can parts made of tinplate, such as those from the DE-PS 35 15 833 also going back to the applicant is known.
  • the can bodies from the station in which they are rolled into a cylinder and longitudinally welded, on their way to the further processing device, on which they are coated with varnish on the inside below the longitudinal seam and the flap Have to cover a distance of more than 30 meters in order to then be further processed, for example, in a device for producing truncated pyramid-shaped can bodies, as is known from DE-OS 37 25 186, which also goes back to the applicant.
  • a device for producing truncated pyramid-shaped can bodies as is known from DE-OS 37 25 186, which also goes back to the applicant.
  • the circular cylindrical can bodies are oval-conically widened over their entire length in a first spreading operation.
  • the frames are then deformed into the truncated pyramid in a second spreading operation, as a result of which the can frame is given the shape suitable for a corned beef can.
  • a device of this type is used on high-performance production lines that produce between 150 and 300 can frames per minute. It is obvious that it is extremely difficult and practically impossible to keep the can bodies so positioned on the transport route that the longitudinal seam in the further shaping device comes exactly into the middle of the narrow side of the finished can body.
  • This position of the longitudinal seam is important so that, on the one hand, the circular cylindrical can frame can be deformed to form the truncated pyramid and, on the other hand, the tab is located at a point on the finished can frame where it does not interfere with the appearance, and its free end can be easily inserted into the slot in the key and its welded end has a position that when the tear strip is rolled up, the longitudinal seam, in the area of which the circumferential scratches are interrupted, can still be torn open reliably and no converging tear lines form.
  • the object of the invention is to provide a method and a device of the type mentioned at the beginning, by means of which a can body can be positioned in such a way that the longitudinal seam of the can body has a precisely defined position during further processing.
  • a method of the type mentioned is characterized according to the invention in that the can body is rotated about its longitudinal axis before further processing until the rotation or the like by a stop protruding into the path of the tab. Obstacle is stopped, and a device of the type mentioned is according to the invention by a frame receiving device, in which the can frame can be accommodated in a fixed space and rotated about its longitudinal axis, and by a stop protruding into the path of the tab or the like. Obstacle to stop the rotation marked.
  • the invention is therefore based on the basic idea of using the tab provided on the outer circumference of each can frame for positioning the can frame in order to bring its longitudinal seam into a defined position for its further processing. This is possible without further ado, because regardless of the manner in which the can frame was provided with the tab, the latter always has a defined or ascertainable distance from the longitudinal seam, which is accurate to 1/10 mm. According to the invention, the defined position of the longitudinal seam can also be exactly maintained, because the can frame is only positioned immediately before it is processed further.
  • the stop can be provided so as to be adjustable in the circumferential direction of the can frame in order to be able to adapt its position if the mentioned distance between the longitudinal seam and the tab should change.
  • the tab simply moves to a fixed me mechanical stop, which stops the rotary movement of the box frame about its longitudinal axis, because the box frame is fixed in space when it rotates, that is, it cannot deflect when the tab and the stop contact.
  • the actually desired detection of the longitudinal seam of the can frame takes place according to the invention.
  • the rotational movement of the can frame about its longitudinal axis is slowed down when the tab on its way to the stop passes a sensor at a point in front of it, which triggers a switching process , by which a speed reduction device is actuated.
  • the can body can then continue to rotate at a slower speed until it reaches the stop, or the speed of rotation of the can body can be increasingly reduced to almost zero when the tab reaches the stop. Either way, this ensures that the tab does not bounce back from the stop if the stop is a mechanical stop and the can body is to be positioned at the highest possible speed.
  • the aforementioned embodiment offers the further advantage that the rotational speed of the can frame can be throttled or reduced to zero when the tab has reached the stop, to avoid unnecessary friction losses between the otherwise rotating magnetic rollers and the closed can frame. Coupled with the process in which chem the shut down can frame is then transferred to the further processing device, the rotary drive of the frame receiving device can be switched on again.
  • the transfer to the further processing device takes place in the direction of the longitudinal axis or parallel to the longitudinal axis of the positioned can frame while maintaining the achieved rotational position thereof.
  • two transfer conveyors are preferably provided, which are guided accordingly and can be moved back and forth.
  • These transfer conveyors have frame drivers, which can be approached to one another up to a mutual distance that is smaller than the diameter of the can frame. So when the frame drivers take the can frame between them, it is deformed oval-cylindrical by diametrically exerted pressure on its outer circumference.
  • this has the advantage that the outer circumference of the can frame moves away from the lateral surfaces of the magnetic rollers, thereby reducing the attractive force exerted by the magnetic rollers on the can frame, and that, on the other hand, the transfer can be made to a tool to which the can frame is supplied in an oval-cylindrical shape anyway must become.
  • the transfer conveyors thus simultaneously form the otherwise required ovalizing device.
  • the rollers are designed as magnetic rollers as a device for holding down the can frame in the frame receiving device, ie to ensure the fixed position of the can frame in the frame receiving device, but it is also readily possible to use another hold-down device in connection with non-magnetic rollers, for example further rolls or rollers which can be adjusted to the outer circumference of the can frame after it has been fed to the frame receiving device.
  • the outer surfaces of the driven roller (s) would be provided with a high coefficient of friction, since with the rotary movement of the can frame is generated as slip-free as possible.
  • the stop can actuate a microswitch or the like. be, so that although a mechanical contact is made between the tab and this obstacle, the stopping of the rotary drive device for the box frame is then carried out electrically.
  • the actuator can simply be a light beam, a magnetic field, an electric field or the like. be so that a contactless actuation of a switching device takes place when moving the tab.
  • the sensor can also be formed without further ado, which is arranged on the frame receiving device along the path of the tab at a point located before the stop.
  • the can frames are simply fed to the frame receiving device via a vertical frame feed shaft by entering at the upper end, in order then to move to the frame receiving device under their own weight.
  • a frame separator is preferably provided in the frame feed shaft at a point which is located directly above the can frame which is received in the frame receiving device.
  • the frame separator preferably has two jaws, which can be moved towards and away from one another transversely to the feed shaft, in order to let one can frame into the frame receiving device and then to keep the weight of the remaining can frames above it from this can frame.
