Definitions

  • the invention relates to a squeezing device having a squeezing unit, which has a feed mechanism with at least one piston rod, and having a receiving unit with a receptacle for an expressible with the at least one piston rod container, wherein the receptacle is bounded at one end by a head part and a head part Having the opposite end, and wherein the receiving unit is releasably secured to the Auspressussi with a holding device arranged on the Auspress unit.
  • Such a squeezing device serves to dispense in containers, such. B. in foil bags or cartridges, packed masses, such as mortar or sealants, at an application site.
  • the at least one piston rod is advanced beyond a predetermined amount, with a pressure plate arranged on the piston rod acting on the container and a corresponding quantity of the mass present therein being discharged through an outlet opening in the head part.
  • a squeezing device which has a squeezing unit with a feed mechanism with two piston rods and a receiving unit with a receptacle for a cartridge which can be pressed out with the piston rods.
  • the receptacle is bounded at one end by a head part and has an end facing away from the head part.
  • the receiving unit is releasably secured to the ejection unit by means of a holding device arranged on the ejection unit.
  • a flange At the end facing away from the head part, a flange is provided, which engages in three U-shaped mutually aligned grooves on the ejection unit and which is engaged behind on its fourth side by a snap-action lever arranged on the ejection unit.
  • the grooves and the snap lever form the holding device arranged on the ejection unit for detachably fixing the receiving unit to the ejection unit and thus an interface of the ejection device.
  • Various types and sizes of containers or cartridges can be set at a squeezing unit.
  • the object of the invention is to provide a squeezing device with a releasable interface between the squeezing unit and the receiving unit, which has a reliable connection and a long service life.
  • the headboard end and the holding device has latching means which can be latched to lock the receiving unit with the Auspress with the Schugreifabitesen the tension elements are.
  • the inventive interface is characterized by a simple design and a secure connection between the squeezing unit and the receiving unit.
  • different lengths of receiving units for receiving different containers such as foil pouches or cartridges, can be set releasably on the ejection unit.
  • the tension elements are designed as tie rods, which have at the end facing the head part a threaded portion on which a clamping element, such as.
  • a clamping element such as.
  • a cartridge is advantageously added, which has at least one tubular receiving space for the mass to be squeezed out.
  • the cartridge is in the fixed state of the receiving unit on the squeezing unit advantageously on the head part of the receiving unit and on a stop surface on the squeezing unit and is held axially immovably in the receptacle.
  • the cartridge is advantageously clamped in the receptacle.
  • the rear engagement portion of the tension elements in conjunction with this engaging behind locking means ensures a backlash-free connection, the connection between the Receiving unit and the squeezing unit is advantageously centered during locking.
  • the locking means releases the rear engagement portions on the tension members and the receiving unit is removable from the ejection unit.
  • the rear engagement portions of the tension members are eyelets, each with a rear engagement opening and the latching means about a pivot axis pivotable latch hooks with latching portions, which are pivoted to lock the receiving unit with the ejection unit in the rear engagement openings of the eyelets.
  • the connection between the receiving unit and the squeezing unit is locked or unlocked.
  • the tension elements When swinging the locking hooks, the tension elements are stretched in the direction of the squeezing unit, which ensures a secure holding of the container inserted in the receptacle in particular during the Auspressvorgang.
  • unlocking the locking portions of the locking hooks pivot out of the rear engagement openings of the eyes of the tension elements, whereby the receiving unit is decoupled from the ejection unit.
  • a guide bevel is provided on the latch hook and the latch hooks are spring-loaded in the direction of the locking position.
  • the holding device preferably has an actuating element acting on the latching means for unlocking the receiving unit from the ejection unit.
  • the latching means of the holding device are brought out of engagement with the Schugreifabitesen the tension elements.
  • the actuating element With the actuating element, a quick-change closure between the receiving unit and the squeezing unit is provided.
  • a transmission element is provided on the actuating element, which can be brought into contact with the latching means in contact surfaces.
  • the transfer surfaces are advantageous at a direction perpendicular to the longitudinal extent of the tension elements or the at least one piston rod projecting part of the transmission element is provided.
  • the transmission element is U-shaped, wherein the engageable with the locking means in contact surfaces are advantageously provided at the free end of the U-shaped transmission element.
  • the holding means is designed as a locking hook pivotable about a pivot axis with a latching section
  • the transmission element of the actuating element for unlocking the receiving unit advantageously acts between the pivot axis and the latching section on the latch hook.
  • the actuating element is spring-loaded and must be moved against the spring force of a spring element for unlocking the locking between the receiving unit and the squeezing unit. After actuation of the actuating element this returns to a starting position, in which the actuating element is no longer acting on the locking means.
  • the in the FIGS. 1 to 3 illustrated extrusion device 11 has a squeezing unit 12 and a receiving unit 32 with a receptacle 34 for a container 33.
  • the container 33 is a multi-chamber cartridge with two juxtaposed tubular receiving bodies for directly receiving the extrudable mass or for indirectly receiving the extrudable mass, which is made available to the user in foil bags.
  • the ejection unit 12 comprises a feed mechanism with two piston rods 13, at the free ends of which pressure plates are provided. Via a manually operable lever 14 on a handle 15 of the feed mechanism is actuated and the piston rod 13 is advanced over a predetermined by the feed mechanism in the direction of the receiving unit 32.
  • the receptacle 34 of the receiving unit 32 is bounded at one end 36 by a head part 35 and has an end 37 facing away from the head part 35.
  • the head part 35 has an outlet opening with a dispensing nozzle 42 in which a mixing element is provided for the mass to be squeezed out of the container 33.
  • On the receiving unit 32 are two laterally extending along the receptacle 34 tie rods as tension members 38 each provided with a rear gripping portion 39 at its, the head portion 35 facing away from the end.
  • the rear gripping portions 39 of the tension members 38 are each formed as eyelets 40, each having a rear engagement opening 43.
  • the tension elements 38 each have at the end in the region of the head part 35 threaded portions and are fixed with nuts 41 on the head part 35.
  • the receiving unit 32 is releasably secured to the ejection unit 12 by a holding device 21 arranged on the ejection unit 12.
  • the holding device 21 has as a latching means about a pivot axis 23 pivotable latch hooks 22 with latching portions 24 which engage behind the latching of the receiving unit 32 with the ejection unit 12 in the rear engagement openings 43 of the eyelets 40.
  • the eyelets 40 form the rear engagement portions 39 of the tension members 38.
  • the locking portions 24 are in the rear engagement openings 43 of the eyelets 40 einschwenkbar.
  • the latch hooks 22 each have a guide bevel 25 and are in the direction of the locking position (see Fig. 2 ) spring loaded.
  • the holding device 21 has an actuating element 26 acting on the latching means with a U-shaped transmission element 28 for unlocking the receiving unit 32 from the ejection unit 12.
  • actuating element 26 acting on the latching means with a U-shaped transmission element 28 for unlocking the receiving unit 32 from the ejection unit 12.
