Definitions

  • the invention relates to a method and a device for opening containers, in particular containers containing contaminant residues, on a conveyor by means of a cutting tool.
  • this known mechanical lid separation also has other decisive disadvantages: there is no opposing knife inside the container (container).
  • the container wall is therefore inevitably pressed in - at least in the first cutting phase - so that residual contents are chambered or stored in the area of the lid / bottom connection; Cleaning is very difficult, particularly when the residual content has hardened.
  • These disadvantages can be kept within limits if the cut is made as close as possible to the bottom / lid.
  • the cutting knife must then be individually adjusted in the cutting height by changing the supports; that always means a considerable amount of time. The frequent setting of the cutting height could at best be restricted by extensive pre-sorting of the containers, which, however, is also very complex.
  • a Cutting or cutting open a container at a greater distance from the bottom / lid is only possible by squeezing the container together with the disadvantages already mentioned.
  • knives sharpened as sharply as possible are necessary, but they dull quickly. This in turn means that the knives are often removed and the machine is shut down accordingly.
  • the invention has for its object to provide a method and an apparatus without the disadvantages mentioned, which allow, in particular, contaminated containers that were filled with environmentally harmful substances to be opened before scrapping with as little effort as possible, so that complete emptying and better cleaning can be achieved.
  • the invention is based on the idea that for other purposes, for example for contour cutting in mechanical engineering, water jet cutting which has been known and used for a long time (see, for example, EP-A-0 145 527) - a water pressure of up to 4,000 bar is possible - into an automatic one
  • a water pressure of up to 4,000 bar is possible - into an automatic one
  • the opening can thus be achieved without generating dust and without generating heat and / or sparks which cause explosions and / or fires.
  • the good visual assessment option after the container cross-section has been exposed allows such a container to be disposed of in special cases for hazardous waste incineration. In addition, it is not necessary for an operator to be in the immediate vicinity of the cutting device.
  • the harmful residual substances can run out and be rinsed out completely via the large container opening thus created, for example during their further transport on the conveyor.
  • a washing system can preferably follow the conveyor.
  • the cutting water running off be fed to the washing system in order to clean the containers.
  • the opened containers can be cleaned either batchwise or continuously, for example via a screw conveyor, and thus completely freed from the harmful residues.
  • the wastewater contaminated at the end of this cleaning process can be treated immediately on site.
  • the subsequent transport and scrapping of the emptied containers that have been completely cleaned by washing is harmless and problem-free.
  • water jet cutting does not result in any of the other dangers that cannot be excluded when using mechanical release agents due to the inevitable heating.
  • the containers be rotated during water jet cutting and preferably lifted off the conveyor at least to separate the bottom. While the container rotates about its longitudinal axis, it can e.g. cut either in the middle or in the immediate vicinity of the base or lid. By lifting the container and cutting off the bottom it is achieved that the residues contained in the container will certainly run down or exit due to gravity. There is also a separation since only the bottom and then the bottomless container can be placed on the conveyor. The residues that emerge or run off during transport are collected by a trough located below the conveyor.
  • the separated lid be lifted off the container body and swung out.
  • This also makes it possible to separate the at least two individual parts of the container; for example, the lid can be pivoted up to a separate lid shelf or also up to a position upstream of the cutting position in the conveying direction above the conveyor and placed there on the conveyor.
  • an automatic mode of operation can also be achieved with containers of different sizes and shapes.
  • the advantageously path-controlled water jet cutting head can, for example, be movable up and down, can be tilted, have a rotating jet nozzle - the container to be opened does not have to rotate - and can be arranged on a portal to the side of the conveyor.
  • the centering holder can be designed so that it can be rotated and / or raised and lowered vertically.
  • the centering holder thus allows the gripped and previously preferably upright aligned container to be rotated, lifted off the conveyor and, after the bottom and / or the cover has been cut off, lowered onto the conveyor, which can be, for example, a conveyor belt.
  • the centering holder can advantageously be provided with pliers arms.
  • the tongs arms are opened, a container is gripped either just above the bottom or just below the lid, and the tongs arms are then closed and raised.
  • either the rotating gun arms after being disengaged from a holder and connected to a rotary drive, for example, rotate the container in the water cutting jet, or the rotating water jet nozzle of the water jet cutting head bypasses the container; Both options then lead to the opening of the container.
  • alternatively circular segment-like centering blocks arranged in a ring with a variable diameter can be fixed on a vertical axis and pivoted radially in or out, depending on the diameter of the container;
  • a synchronous motion sequence can be achieved by connecting all vertical axes to one drive.
  • a scanning device preferably a light barrier
  • the water jet cutting head it is advisable to connect a scanning device, preferably a light barrier, to the water jet cutting head to determine the container dimensions.
  • a scanning device preferably a light barrier
  • automatic operation can also be achieved, particularly in the case of containers of different shapes and in particular sizes and heights.
  • the scanning device and the water jet cutting head can also be mechanically connected to one another. Movement-dependent positions can be achieved by means of, for example, a parallelogram-type articulated lever connection, only one drive being required.
  • the separated lid can be carried out, for example, in a separate lid storage.
  • the rotation of the container can optionally be initiated to cut off the lid.
  • a pneumatically operated suction cup could be used to lift and remove the cover, making sure that no air is sucked in through the cover-side bunghole.
  • a collecting trough is preferably arranged under the conveyor, the residues running out of the opened containers can be collected in a targeted manner without stressing the surroundings.
  • the conveyor can be in several parts and preferably consist of a feed conveyor and a discharge conveyor and have a bar grate between these two conveyors.
  • a bar grating bridging the distance between the discharge end of the loading conveyor and the discharge end of the discharge conveyor has the advantage that cutting water and / or pollutant residues emerging from the opened containers can run downwards before the container parts reach the discharge conveyor, for example upstream of the washing drum.
  • the bar grate is preferably pivotally mounted, it can be pivoted transversely to the transport direction and placed in such an inclined position that the separated lids, especially if they should be made of plastic, can be separated from the other parts of the container; the separated parts therefore do not get onto the discharge conveyor.
  • the conveyors can be designed with endless conveyor belts.
  • a feed conveyor having a rigid container receiving bed is preferred.
  • a rigid, e.g. Sheet-shaped, advantageously V-shaped receiving bed in cross section is less susceptible to wear than a conveyor belt. Due to the V-shaped cross-section, the containers can be laid horizontally, i.e. With its cover or bottom in the direction of transport, give up the receiving bed, which is advantageously inclined in the direction of transport and thus promotes the targeted drainage of cutting water and / or residual pollutants.
  • a centering device securing the container for cutting through can possibly be completely omitted in such a loading conveyor.
  • the containers are fed in such a way that they protrude slightly above the receiving bed of the feed conveyor with their end on the bottom or lid to separate the corresponding container part, so that the water jet nozzle or the water jet cutting head can run freely around.
  • the receiving bed can have a slot that extends over the entire length and an endless chain that is arranged underneath the receiving bed and is provided with at least one driving finger that passes through the slot into the receiving bed protrudes.
  • a drive located below the receiving bed allows the conveyor to be short. It is especially recommended if there are containers with large differences in size itself to provide several driving fingers and thus prevent the containers from jamming and / or a transport jam, since correspondingly fewer containers lay against one another.
  • the containers centered in the prismatic guide of the receiving bed are gradually conveyed into their cutting position projecting from the receiving bed.
  • a loading slide sweeps the receiving bed.
  • a feed slide that is moved axially back and forth, for example by means of a chain, a rope or a toothed rack, there is a very simple, robust loading unit; since the receiving bed is also completely closed, the cutting water and / or residual pollutants in particular cannot escape downwards.
  • the loading slide can be extended on the side facing away from its top surface and provided with a cover plate designed as a container receptacle.
  • the cover plate suitable for container pick-up enables a very fast, essentially continuous loading of the loading bed of the loading conveyor. As soon as the feed slide moved to its foremost position has transported the last container into its cutting position and is then pulled back, the containers lying on the cover plate hit a non-return flap so that they slide off the cover plate and onto the receiving plate when the load slide moves further back fall or slide and thus fill them simultaneously with the return stroke of the feed slide.
  • a positioning bed is arranged transversely to the direction of transport at the head end of the loading conveyor. This way you can cut through carry out the container in the positioning bed, preferably brought into a cutting position by a positioning slide, independently of filling the loading conveyor with containers.
  • the receiving plate of the feed conveyor which also serves as a buffer in this arrangement can be flat, ie the containers roll or slide with their lateral surfaces on or over the receiving bed; a centering necessary for cutting through and therefore a V-shaped cross section only has the positioning bed.
  • a lifting and lowering locking slide is arranged in the transition from the feed conveyor to the positioning bed, the selective feeding of the containers can be supported and prevented that more than one container gets onto the positioning bed.
  • the feed conveyor prefferably with a longitudinal wall that can be adjusted transversely to the transport direction.
  • the longitudinal wall can serve as an abutment for an operator when filling the loading conveyor with containers and thus facilitate the sorting or loading of containers of approximately the same size.
  • a stop can be placed upstream from the head end of the feed conveyor and / or the positioning bed.
  • the axially adjustable stop ensures that the protrusion is always sufficient, because a container is always advanced either by the loading or positioning slide until it hits the stop.
  • the container can be cut in the prismatic guide of the receiving or. Clamp the positioning bed.
  • a guide wall according to claim 39 be arranged on a long side of the conveyor belt of the loading conveyor. This guide wall, against which the containers rest, serves as a reference line for the targeted feeding of the containers into the centering holder assigned to the water jet cutting head.
  • the water jet cutting head is preferably connected in the transport direction to an adjustable slide that is designed according to claim 40, an exact setting of the water jet cutting head can be achieved for each container dimension and shape, which is namely always adjusted so that the jet nozzle of the water jet cutting head is in the starting position is aligned with the center of the axes of symmetry of the container.
  • the adjusting slide is moved towards the guide wall until it has reached the container and fixes it in the corner formed by the stop bar and the guide wall. In this position, the scanning device can determine the exact size and contour of the container and forward it as a control signal to the water jet cutting head.
  • the adjusting slide can advantageously be arranged on a slide guide which can be raised and lowered and / or pivoted in and out over the conveyor belt.
  • the adjustment slide is thus only in the area of the conveyor belt during positioning and allows the containers to pass unhindered during transport.
  • a container 1 there are empty containers 2 in which remnants are still left.
  • the container 1 is located in the immediate vicinity of a system 3 for automatically transporting, opening, emptying and cleaning the containers 2.
  • An operator 4 removes the containers 2 of different shapes and sizes in any order from the container 1 and places them upright on a drive - and / or deflection rollers 5 endlessly revolving conveyor belt 6.
  • the containers 2 On their way in the transport direction 7 (cf. the arrow in FIG. 1), the containers 2 first pass a height-adjustable light barrier 8 which measures the dimensions, in particular the height, of the containers 2 determined and outputs a corresponding measurement signal to a centering holder 9 connected downstream in the transport direction 7 and to a water jet cutting head 11.
  • the centering holder 9 has two pliers arms 12 which have recesses on the inside facing one another, which in the closed state form a clamping prism 13, and are connected to a rotary drive 14 (for example a friction wheel) (cf. FIG. 2). While the pliers arms 12 are rotating in the direction of the arrow 15, the water jet cutting head 11 arranged on a portal 17 which can be adjusted according to the arrow 16 cuts off the lid 18 (FIG. 1) of the container 2.

  • the conveyor belt 6 is followed by a washing drum 27 into which the opened containers 2 are transported for final cleaning.
  • the centering holder 9 grips the container 2 with its tong arms 12 just below the lid 18.
  • the water jet nozzle 28 of the water jet cutting head 11, not shown in FIG. 3 cuts off the bottom 29 of the container 2 in this case, namely after the container 2 has been lifted off the conveyor belt 6 by the centering holder 9, which can be raised and lowered.
  • the system 3 for the automatic transport, gripping, opening, emptying and cleaning of the containers 2 according to FIG. 4 consists of a feed conveyor 32 having an endlessly rotating conveyor belt 6, to which a discharge conveyor 34 designed as an endlessly rotating conveyor belt 34 is located at its head end (discharge end) connects.
