Definitions

  • the invention relates to a device for metered delivery of flowing media, in particular hot melt adhesive, cold glue, lubricants, colors od.
  • an applicator head which has a boundary surface, in the numerous, provided for a flowing medium supply channels open, and at least one the boundary surface arranged application module, which od with a nozzle head for applying adhesive dots, adhesive lines.
  • application module which od with a nozzle head for applying adhesive dots, adhesive lines.
  • the like. Is provided on a moving past substrate.
  • Such a device is known from the document EP-A-0719591, in which the application modules can be attached in each case with two cylinder head screws to the order of the supply of the application module application head.
  • the threads can be damaged so that attachment of a new job module is no longer possible, so that the entire application head removed from the machine and new cylinder head bolts must be used. This then means a longer production downtime.
  • the object of the invention is now to develop a new device for metered delivery of flowing media, in which the order module attachment or replacement is significantly simplified.
  • the device according to the invention has, first of all, the significant advantage that the threads provided for fastening the locating bolts in the application head do not have to be loosened when the application module is changed, and thus on the one hand no wear due to assembly operations are exposed and on the other hand can not be damaged by leaking adhesive. Also can be achieved by simply pushing the job module on the fixedly arranged on the application head receiving bolt already a safe pre-assembly, in which case an immovable attachment is guaranteed by pressing the clamping element.
  • an abutment plate which detects both end regions of the locating bolt can also be arranged between the tensioning element and the application module.
  • the end portions of the locating pins are each provided with a clamping head having an enlarged diameter relative to an upstream engaging groove
  • the engagement groove provided for the abutment plate being provided with a reduced diameter relative to the locating pin
  • the abutment plate being formed as a sliding plate is, which has for receiving the end portions of the locating bolt in the direction of gravity extending slots having against the direction of gravity a first region having a diameter having a diameter of the clamping head diameter exceeding, while in the direction of gravity in a second region of the diameter of the slots only slightly greater than the diameter of the bolt in the region of the engagement groove.
  • the abutment plate is advantageously designed so that it secures the pre-assembly in the non-tensioned state and in clamped state, a tension of the sliding plate formed as an abutment plate is achieved.
  • the clamping element is formed from a pressure screw arranged in a threaded bore of the abutment plate / sliding plate, which is supported on an outer surface of the application module.
  • a device for the metered delivery of flowing media is designated overall by the reference numeral 10.
  • Such a device 10 has an application head 11 and at least one application module 12, which is provided with a nozzle head 13.
  • Fig. 1 the device 10 is shown in detail, wherein only those elements are to be described below, which have a relation to the invention.
  • the feed of the glue to be delivered via the application module 12 is initially effected via a filter block 14 and a connecting channel 15 to the pressure distribution channel 16, which is connected via a further channel 17 to a main distribution channel 18.
  • the mouth regions of the glue supply channels 19 correspond to the attachment of the application modules 12 with corresponding glue supply channels (not shown) in the order module 12.
  • a heating cartridge 21 is arranged in the region of the previously described glue feed.
  • an air heater 22 is provided below the glue supply, which provides the necessary heated spray air available.
  • the device 10 is shown in fragmentary perspective view. It can be seen that four application modules 12 are already attached to the application head 11 by means of fastening devices 23, wherein two locating bolts 24 can be seen at the fifth fastening position, which are arranged in threaded bores 25 of the boundary surfaces 20. In order to achieve a pre-assembly position, the application module 12 can now be slid onto the locating bolts 24 due to the boreholes 24 present in the latter, but not shown.
  • the fastening device 23 initially has the aforementioned locating bolts 24. At the end face facing the boundary surface 20, the locating pin 24 is provided with a thread 26 and a stop ring 27. This is followed by a spacer 28 which passes through a bore, not shown, of the application module 12, an engagement groove 29 for a sliding plate 30 and a clamping head 31 is present.
  • the locating pin 24 has a diameter d 1 in the area of the engagement groove 29 and a diameter d 2 in the area of the clamping head 31.
  • the fastening device 23 has the sliding plate 30, which is provided in its upper region (see Fig. 2) with two spaced slots 32 for the locating pins 24, between which a threaded bore 33 is arranged for a pressure screw 34 provided with a hexagon socket , Above the threaded bore 33 is still a bore 35 for a guide pin 36 is present.
  • the slots 32 have in their upper region a diameter d 3 , which is slightly larger than the diameter d 2 of the clamping head 31, while the diameter d 4 of the lower portion of the slots 32 is smaller than the diameter d 2 of the clamping head (31). and slightly larger than the diameter d 1 in the region of the engagement groove 29. The reason for these different diameter ratios will be given below.
  • an application module 12 is to be fastened to the application head 11
  • the application module 12 provided with a sliding plate 30 can first be pushed onto the mounting bolts 24 to such an extent that the clamping heads 31 move out of the sliding plate 30 in the region of the diameter d 3 protrude. In this position, a safe pre-assembly position is initially reached.
  • the clamping head 31 reaches and the engagement groove 29 the region of the diameter d 4 of the elongated hole 32, whereby the chuck 31 receives the function of an abutment.
  • the pressure screw 34 is moved for example by a half turn in the direction of the outer surface 39 of the application module 12 and causes a distortion of the sliding plate 30 with simultaneous pressing of the application module 12 to the boundary surface 20 of the applicator head 11 (see Fig. 4). Now an immovable attachment of the application module 12 is reached, however, can be canceled at any time by loosening the pressure screw 34 again.
