Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • Such a device is known from DE-OS 26 36 oo3, in which a lifting device is provided, on which a lifting plate is attached.
  • This lifting plate is assigned a closure plate which can be displaced relative to it within limits and which can be sealed against the lower edge of the vacuum bell.
  • a device consisting of a plate with a permanent magnet for lifting the lid from the can is elastically displaceably mounted.
  • the lifting device conveys the lifting plate with the can until the lid adheres to the permanent magnet.
  • the lifting plate with the can is slightly lowered again, but the vacuum bell remains tightly closed. This is followed by evacuation and, if necessary, partial gassing with protective gas.
  • the lifting plate with the can is raised again until the lid rests on the can.
  • the can can then be pushed up further, at the same time pressing the edge of the lid. Then the vacuum chamber in the vacuum bell is ventilated again; the lifting plate with the closed box can be moved down again.
  • This device has proven itself extremely well as a semi-automatic device; on the one hand, it is not suitable for extremely high outputs and, on the other hand, it is not suitable for use with differently sized cans.
  • a device for closing cans each with a lid under vacuum, which has a vacuum space which can be moved vertically by means of two lifting devices relative to one another into a closed position and from one another into an open position of the vacuum space upper or lower vacuum bell is formed.
  • a third drive is also provided, by means of which a pressure plate of a closing device can be actuated. The procedure is such that a lid provided with a lid is placed on a lower plate-like receptacle after lowering the lower vacuum bell and then the lower vacuum bell is moved up and the upper vacuum bell down until the vacuum chamber is closed.
  • the pressure plate provided with a permanent magnet or the like is moved against the cover and then moved back, the cover adhering to the pressure plate.
  • the vacuum chamber is then evacuated and the lid is then pressed onto the can by means of the pressure plate.
  • the vacuum chamber is ventilated again and the two vacuum bells are moved downwards and upwards.
  • the configuration according to the invention ensures that the individual work steps and the lifting heights of the lifting devices do not need to be changed if cans of different sizes, for example 2.5 kg cans and tkg cans, are to be sealed.
  • the measures according to claim 3 ensure that the closing station can be adapted to different cover diameters within predetermined tolerance limits. Such slight fluctuations in the lid diameter occur from lot to lot.
  • the measures according to claim 3, however, ensure that even with such different lid diameters, a uniformly firm and secure closure of the can is achieved.
  • the measures according to claim 5 already ensure during evacuation and, if necessary, fumigation of the cans that the lid and the can are assigned to one another as precisely as possible.
  • the device shown in the drawing has a degassing station 1 and a closing station 2. These stations 1, 2 are mounted on identical frames 3, 4 arranged directly next to one another.
  • a conveyor track 5 is provided which, viewed in the conveying direction 6 of cans 7, leads through the degassing station 1 and through the downstream closing station 2.
  • cans 7 are conveyed in cycles with conveyor devices (not shown in detail) and fed to the stations 1, 2.
  • two degassing devices and two closing devices are arranged in the closing station 2, so that two cans 7 can be degassed or sealed at the same time.
  • the cans 7 to be used here are known, for example, from DE-OS 22 63 362.
  • each degassing is - roughly speaking - from a lifting device 9 and a degassing chamber 1 0th
  • Each lifting device 9 consists of a pneumatically actuated working cylinder 11, which is attached to the frame 3 below the conveyor track 5 and to the upwardly projecting piston rod 12 a lifting plate 13 is fastened. In the lower end position of the lifting plate 13 shown on the right in FIG. 1, it lies flush with the conveyor track 5, so that a can 7 can be pushed onto it without further ado.
  • the gasification chamber 1 0 is coaxial with the lifter 9 above it.
  • the bell 14 is closed at the top by a gas-tight, for example welded, annular cover plate 17, to which a bushing serving as an actuating cylinder 18 is screwed coaxially.
  • This actuating cylinder 18 is in turn attached to a bracket 19 of the frame 3.
  • An actuating piston 20 is arranged in the actuating cylinder 18 so that it can be displaced coaxially with the degassing device. It carries at its lower end a concentrically arranged permanent magnet 21 and approximately flush with it a retaining ring 22. Above the actuating piston 2o, the actuating cylinder 18 is closed by means of a cylinder end cover 23 screwed on and sealed from above, through which a return rod 24 extends, which extends with it lower end is screwed into the adjusting piston 2o.
  • the return rod 24 penetrates a package of springs 25 resting on the top of the cylinder cover 23, namely disc springs, on which there rests from above a stop 26 designed as a downwardly open bushing, which is screwed onto the return rod 24 from above, thereby preloading the Springs 25 is adjustable.
  • a channel 27 for the supply or discharge of pressure medium, usually compressed air opens into a working space 28 of the actuating cylinder 18, namely between the cylinder end cover 23 and the actuating piston 2 0 .
  • the bell 14 is provided with a connection 29 for evacuating and gassing the degassing chamber 10.
  • the inner wall of the bell 14 is provided with a centering surface 3o which tapers conically upwards. .
  • a closing device has a pneumatically actuated lifting cylinder 31, which is attached to the frame 4 below the conveyor track 5 and on whose piston rod 32 which is led out upwards, a lifting plate 33 which is the same as the lifting plate 13 is attached.
  • a closing unit 35 is arranged coaxially with this lifting device 34 as part of the closing device.
  • the closing unit 35 has a closing bell 36 which is open at the bottom and which has an upwardly tapering, frustoconical pressing surface 37.
  • the closing bell 36 which is closed at the top by a cover plate 38, is likewise attached to a bracket 4o of the frame 4 via a bushing which is arranged coaxially and serves as an actuating cylinder 39.
  • An actuating piston 41 is arranged in the actuating cylinder 39, and a stop ring 42 is screwed onto its lower end. This stop ring 42 has a circumferential centering collar 43 in its lower outer region.
  • This actuating cylinder 39 is also closed at the top by a screwed-on cylinder cover 44, through which a channel 45 for supplying or discharging a pressure medium, such as compressed air, into a working space 46 of the actuating cylinder 39 between the top of the actuating piston 41 and the underside of the cylinder cover 44 is arranged.
  • a pressure medium such as compressed air
  • a reducer 52 designed as a plate, can be screwed onto the underside of the retaining ring 22 of the degassing chamber 1o to change over to cans 7 'of lesser height, and a permanent magnet 21' is concentrically attached to the underside thereof.
  • an approximately cylindrical ring-shaped reducing piece 53 can be introduced into the bell 14 for adaptation to cans 7 ′ with a smaller diameter, which reducer is releasably locked to the bell 14 by means of resilient ball closures 54.
  • This reducer 53 also has in its upper region adjacent to the underside of the reducer 52 a centering surface 3o 'which tapers conically upwards. It is furthermore provided with degassing openings 55, which are connected to the connection 29 via an annular channel 56 screwed into the outer surface of the reducer 53.
  • the can 7 with the cover 8 remains on the lifting plate 13, ie the cover 8 is torn off by the permanent magnet 21, since the magnet 21 is not as strong on the one hand, to hold the weight of the filled can and on the other hand, due to the pressure difference of the lid 8, is already sitting relatively firmly on the can.
