Definitions

  • the invention relates to a refuse dump column according to the preamble of claim 1.
  • a refuse dump column of this type is known from NL-C-1007663.
  • the follower means consist of a follower rail fixed to the shut-off means, diametrically opposite the shut-off means with respect to its shaft, and a follower arm fixed to the blocking means near the shaft of the blocking means, one end of which arm rests upon the follower rail, for the purpose of following the movement of the shut-off means.
  • the follower rail is in the shape of an arc over the greater part thereof relative to the shaft of the shut-off means, while at the end of the rail that is situated closest to the shaft of the blocking means the rail passes by way of a bend into a straight follower part, which from the arcuate follower part onwards extends further from the shaft of the shut-off means.
  • the angle through which the blocking means rotates between its blocking position and its admission position is determined by the angle of the bend of the follower rail and the length of the straight part of the follower rail.
  • the bend angle and the length of the straight part of the follower rail also determine relative to the shaft of the shut-off means a length of arc over which the follower element follows the straight part of the follower rail.
  • the greater the angle through which the blocking means can rotate the greater the abovementioned arc distance is and, corresponding to this, the greater is a height of the throw-in aperture of the column over which the blocking means can rotate during movement of the shut-off means.
  • the shut-off means When the shut-off means is rotated to its shut-off position after waste has been deposited on the blocking means in the column, the weight of the waste and the blocking means will result in the blocking means suddenly rotating forcefully into its blocking position after the follower element has passed the bend of the follower rail.
  • the height of the throw-in aperture over which the blocking means can rotate In order to prevent injury to fingers or hands which may be inserted into the throw-in aperture, it is therefore desirable for the height of the throw-in aperture over which the blocking means can rotate to be small. In order to reduce this height, it is necessary for the bend of the follower rail to be sharper, in other words, its straight part must extend in a more radial manner.
  • the refuse dump column In addition it is desired for the refuse dump column to be operable without great difficulty by all users. Therefore, with the known column the height of the throw-in aperture over which the blocking means rotates will be greater than the thickness of a finger or even of a hand. This means that there is a great risk of physical injury.
  • the object of the invention is to eliminate the drawbacks of the known refuse dump column.
  • the invention therefore provides a refuse dump column according to claim 1.
  • the height of the throw-in aperture over which the blocking means rotates during closure can be reduced considerably and the risk of injury to fingers or hands inserted into the throw-in aperture is reduced considerably.
  • Fig. 1 shows a phantom view of a preferred embodiment of a refuse dump column according to the invention, from one side.
  • the column comprises a housing 2 with a vertical passage 3 which has a throw-in aperture 4 on the top side and an outflow aperture 5 on the bottom side.
  • the refuse dump column is suitable to be placed above a charging aperture of a collection container (not shown).
  • a shut-off means formed by a lid 7 is fixed in such a way that it is rotatable about a horizontal shaft 8 fixed to a fixing structure 9, which is fixed on the inside wall of the housing 2.
  • the column In Fig. 1 the column is in a position in which the lid 7 is covering the throw-in aperture 4.
  • parts of the wall of the housing 2 and the part of the lid 7 towards which the viewer normally looks are omitted in Fig. 1.
  • the lid 7 is rotatable about the shaft 8 by way of a connecting plate 11 fixed to the lid 7.
  • a cam 12 which is rotatable independently about the shaft 8, is fitted.
  • An arm 14 is fixed by way of a shaft coupling with a shaft 15 in a rotatable manner on the fixing structure 9. All shafts already mentioned and yet to be mentioned, such as 8 and 15, are horizontal, parallel to each other and parallel to a main surface of the throw-in aperture 4.
  • a blocking means formed by a baffle plate 16, is fitted in the passage 3.
  • the baffle plate 16 is rotatable about a shaft 17. Between the bottom end of the arm 14 and a point of the baffle plate 16 below the shaft 17 a connecting element 19 is connected in such a way that the connecting element 19 can swing relative to the arm 14 and the baffle plate 16.
  • the connecting element 19 is shown as a rod, but can also be a piece of cable or the like.
  • the shape of the fixing structure 9, which consists of plates, and that of the baffle plate 16 are determined by the peripheral shape of the inside wall of the housing 2.
  • a pin 22 or the like is fixed to the fixing plate 11 for the lid 7, which pin projects into an opening 23 of the cam 12.
  • Fig. 2 shows this on a larger scale.
  • a handle 24 is fixed on the lid 7.
  • the baffle plate 16 will be lifted over a relatively great distance already after a small rotation movement of the lid 7 in the direction of the arrow 26 and will quickly substantially block the passage 3, as shown in Figs. 4 and 5.
  • baffle plate 16 Since during the upward rotation of the lid 7 to the throw-in position the baffle plate 16 is generally not carrying any material, a user still need only exert a relatively slight lifting force on the handle 24, despite the short distance between the top point of the cam 12 and the shaft 15.
  • a refuse dump column can work in the manner explained above using a cam 12 which has an opening in the form of a hole into which the pin 22 fits with slight play.
  • the opening 23 is, however, larger than the pin 22, in such a way that the cam 12 can rotate over a length of arc relative to the pin 22.
  • the opening 23 is in particular, but not necessarily, a slot, as shown.
  • the opening 23 relative to the shaft is over a length of arc greater than the pin 22, it is ensured that when the lid 7 is rotated back from the throw-in position shown in Fig. 5 in the direction of the arrow 28 to the shut-off position shown in Fig. 1, the rotation back of the cam 12 is delayed until, as shown in Figs. 6 and 7, the pin 22 reaches the side of the opening 23 situated opposite the side of the opening 23 against which the pin 22 rests during the opening of the lid 7.
  • the arm 14 is supported for a relatively long time by the cam 12 and the baffle plate 16 shuts off the passage 3 for a correspondingly long time.
  • the length of arc of the opening 23 can be altered without it affecting the amount of force needed for lifting the lid 7 out of the shut-off position.
  • the operation of the refuse dump column according to the invention provided with the ample opening 23 of the cam 12 explained above is as an operation with hysteresis, in particular asymmetrical hysteresis.
  • Hysteresis is possible in another way, for example by means of a mechanism (not shown) fitted between the housing 5, the lid 7 and the baffle plate 16 with bistable control pawls and locking pawls.
  • the opening 23 a length of arc with which the height of the throw-in aperture 4 at the moment when the baffle plate 16 can rotate to the admission position shown in Fig. 1 is less than the thickness of a finger of the user. This prevents physical injury from occurring.
