Definitions

  • the invention relates to a spray lance for applying pasty media with a shut-off device arranged in a housing that can be rotated to a limited extent stored and actuated by a lever.
  • Spray lances of this type are arranged with two separate from each other Two position switches equipped to drive the drive motor on the one hand Switch feed pump on and off and on the other hand actuate the shut-off device can. Since spraying is only possible when the shut-off device is open its actuation inevitably when the sprayer is started up when It does not stop the feed pump by switching off the drive motor but often to open the shut-off device. In this case there is Delivery line sometimes a high pressure over a longer period, through which a the hose forming the delivery line is damaged or even torn suddenly can be. Since there is often no pressure relief, this is a big one Given the risk of an accident.
  • spray lances or spray guns for application are, for example pasty media generally known, in which a arranged in a housing Shut-off device can be operated using a lever and in one on the spray gun attached holder (e.g. handle) a switching element is used, which with a, a delivery pump associated with the delivery line connected to the spray lance connected and with a contactlessly interacting with the switching element Switch flag is provided to the feed pump depending on the shut-off device For example, to be able to switch on and off in such a way that none in the supply line unnecessary pressure remains after closing the shut-off device (DE 33 31 617 A1, DE 196 12 524 A1, DE-GM 76 13 155).
  • the object of the invention is therefore to provide a spray lance for applying pasty To create media in which it is reliably ensured that when the Delivery pump in the delivery line is no longer pressure, it should be immediately dismantled and the delivery line should inevitably be relieved of pressure.
  • the risk of accidents caused by bursting delivery lines should therefore be almost zero be excluded, it should also be ensured that the drive motor of the Feed pump in operation without having to overcome a back pressure can be taken.
  • simple handling With simple handling, the Operating behavior of a system that is equipped with such a spray lance, in to be improved to a considerable extent.
  • the switching element as a coded reed contact switch or train as an electronic proximity switch and the switching flag by a Permanent magnet or one in an existing plastic Switching ring to form inserted metal plate.
  • shut-off device To limit the torsion path of the shut-off device, it is appropriate if whose housing has a protruding attachment piece and with the shut-off device a sleeve overlapping its housing is firmly connected, into which a Circumferential recess is incorporated into which the extension piece intervenes.
  • the switching ring with a stop protruding into it in the form of a plate or a pin to limit the Adjustment path of the switching ring with that on the housing of the shut-off device attached connector cooperates.
  • a friction-increasing surface in the form of a sealing ring or one in this inserted spring catch should be provided, further should lock the Switching ring in the closed position of the shut-off member in a molded on the lever on the plate lying on the switching ring associated with its adjustment path Cam track incorporated and an axially directed pin inserted in the switching ring be who engages in the cam track.
  • the shut-off device can be designed as a ball track.
  • the spray lance shown in Figures 1 to 3 and each designated 1 is used to apply pasty media, which, as shown schematically in Figure 4 is reproduced, this from a reservoir 5 via a delivery line 6 with A feed pump 7 can be fed and in which a switching element is inserted.
  • she consists essentially of a ball valve used in a housing 2 trained shut-off device 3, which is adjustable by means of a lever 4.
  • the lever 4 is designed in the area of the housing 2 as a plate 4 'on which a cover plate 8 rests and is held by means of screws 10.
  • a mother 9 that is Shut-off device 3 attached to plate 4 'in a manner fixed against relative rotation can be rotated in housing 2 clamped, and through a seal 20, the passage through the housing 2nd secured.
  • the shut-off device 3 is also assigned a switching ring 11, which on a Sleeve 15 is rotatably placed, which is also by means of the screws 10 on the Plate 4 'of the lever 4 is attached. And the switching ring 11 acts with a switching element 13 together, which is installed in a holder 12 placed on the spray lance 1 is. Via a control line 13 'is the switching element 13, which is shown in the Embodiment is designed as a reed contact switch with which not in individually shown drive motor of the feed pump 7 connected, so that this in Depending on the respective position of one arranged in the switching ring 11 Switch flag 14 is to be actuated in the form of a permanent magnet.
  • the shut-off device 3 is rotatably supported in the housing 2 to a limited extent.
  • a projecting extension 17 is formed on the housing 2, and in the sleeve 15, as this is particularly the sectional views according to the FIGS. 6, 9 and 11 show a cutout 16 in the form of a sector incorporated into which the extension 17 engages.
  • With the attachment 17 acts further a stop 18 together, which by a in the switching ring 11th inserted plate is formed.
  • the path of rotation of the switching ring 11 is thus also limited.
  • a seal 19 is located between the plate 4 'of the lever 4 and the switching ring 11 provided to the switching ring 11 by adjusting the shut-off device 3 by friction and thus return to the starting position can.
  • a spring catch 23 are used in the switching ring 11, which in the two end positions of the switching ring 11 incorporated into the plate 4 ' Recesses 24 engages.
  • the switching ring 11 is axially projecting Provide pin 2, the in an assigned in the plate 4 'incorporated cam track 22 protrudes.
  • FIG. 1 shows the operating position of the spray lance 1, the shut-off device 3 is open here, and the drive motor of the feed pump is 7 turned on because the switching element 13 by the opposite arranged switching flag 14 is excited.
  • the switching ring 11 and thus the switching flag 14 rotated by up to 90 °, so the Drive motor of the feed pump 7, since this via the control line 13 'no corresponding signal is fed in, switched off and the feed pump 7 is stopped.
  • the shut-off device 3 of the spray lance 1 is still open, the pressure in the delivery line 6 is reduced and the delivery pump 7 must restarting do not work against a locked-in pressure.
  • FIGS. 5 to 7 show the operating state according to Figure 1, Figures 8 to 10 the position of the switching ring 11 rotated relative to FIGS. 5 to 7 Stop the feed pump 7 and Figures 11 to 13 shut off Delivery line 6 with delivery pump 7 switched off.
  • the feed pump 7, as shown in FIGS. 8 to 10, is already switched off, keeps 6 when shutting off the delivery line by turning the Shut-off 3 of the switching ring 11 in its position, since the inserted in this Stop 18 abuts the extension 17 of the housing 2.
  • open Shut-off device 3 can thus twist the switching ring 11 relative to this in order to switch off the feed pump 7 in the closed position of the Shutoff 3, the switching ring 11 is locked, however, and only together with the Shut-off device 3 attributed to the starting position. With easy handling is accordingly an always reliable actuation of the spray lance 1 is ensured.
