Definitions

  • the invention relates to a device for dispensing flowable substances, in particular adhesives, paints, varnishes and release agents.
  • Such devices are used, for example, to apply in portions adhesives on a substrate.
  • the application of the adhesives is controlled by a metering valve, in particular a line, dot, spray, spiral or surface application is possible.
  • a problem in the processing of flowable substances with metering valves that residues of the substance can accumulate at the outlet of the metering valve and, especially if they harden there, can interfere with the subsequent operation of the device or even bring to a standstill.
  • the actuating means has a slide whose end is slidably formed via an outlet opening of the nozzle and this opens or closes immediately.
  • the slider is a rectangular cross-section, elongated metal plate which is arranged in a slide housing in which there is a return spring which holds the slider in the closed position.
  • the actual closure thereby forms a closure piece located in a recess on the closure-side end of the slide, which consists of a silicone sponge soaked in oil or non-stick agent or of a wedge-shaped plastic part inclined towards the outlet opening of the nozzle.
  • the slider housing is fixedly connected to a support arm on which a receiving holder for a metering valve, which has the nozzle, is attached.
  • a device for dispensing flowable materials is further in the DE 199 36 670 C1 described.
  • This device comprises a fixed support, a metering valve with discharge nozzle for the flowable substances which is connected to the carrier, and also an outer closure part for closing the outlet opening of the nozzle.
  • the closure part is arranged stationary and it is the metering valve or the nozzle pivoted relative to the closure part.
  • a leading edge of the closure part contacts the nozzle in the region of the free nozzle end during the respective closing operation, with the described disadvantage of increased wear of the closure part in the region of the leading edge.
  • This device also builds compact because of the pivotal arrangement of the metering valve.
  • a device for dispensing flowable substances with a nozzle and a closure member for the nozzle is further from the EP 0 719 592 A2 known. Also in this device contacted a leading edge of the closure member when transferring the closure member in its closed position, the nozzle in the region of the free nozzle end.
  • the object of the present invention is to further develop a device for dispensing flowable substances, which has the features of the preamble of patent claim 1, in such a way that the closure part can be transferred in a non-linear movement from the open position to the closed position in a more compact manner Design of the actuating means in the direction perpendicular to the direction of movement of the closure part.
  • the movement of the closure part from the open position to the closed position and from the closed position to the open position is thus accomplished by means of the transmission medium.
  • This requires in the direction perpendicular to the direction of movement of the closure part little space, since it is designed compact in this direction.
  • This makes it possible to arrange a plurality of devices, thus having a plurality of nozzle metering units relatively close to the side by side.
  • the transmission medium is a robust, permanently safe drive for moving the closure part.
  • the bearing element is defined pivotally mounted in these wheels, whereby a precise guidance of the bearing element is ensured. This ensures a precise process of the closure part between open position and closed position.
  • the bearing of the bearing element in the wheels causes the bearing element and thus the locking element mounted in the bearing element to perform a non-linear movement when the drive is actuated.
  • the bearing axes of the bearing element in the wheels move, according to the pivoting movements the wheels on a circular path, whereby the closure part moves on a circular path. This basically makes it possible to position the closure part with respect to the nozzle such that a leading edge of the closure part does not come into contact with the nozzle but is moved past the nozzle, so that the closure part only hangs flat on the outlet opening of the nozzle behind the leading edge ,
  • the device according to the invention allows a simple movement of the closure part from the open position to the closed position and vice versa. This movement is due to the driving of the transmission medium in opposite directions, whereby wheels, for transferring the closure part from the open position to the closed position, in a pivoting direction and, for transferring from the closed position to the open position, in the opposite pivoting direction are moved.
  • the drive has a linear-acting actuator and a spring.
  • the transmission medium can be delivered in one direction of travel and by means of the spring the transmission medium in the opposite direction can be reset.
  • the closure part is adjustable by means of the actuator in its open position and by means of the spring in its closed position.
  • the actuator is designed for example as a pneumatically acting cylinder.
  • the drive in particular has a reciprocable connecting element which is connected to the transmission medium.
  • the drive acts together.
  • the pneumatic cylinder when exposed to air, acts on the connector in the sense that it is being moved in one direction of travel. If the pneumatically effective cylinder is depressurized, the spring acts in particular directly on the cylinder, so that the cylinder is reset and in this case the connecting element is returned to the starting position.
  • the connecting element is connected to a straight portion of the transmission medium and can be moved rectilinearly in opposite directions.
  • the connecting element thus engages in that region of the transmission medium to this, in which a connecting element of the associated portion of the transmission medium is formed in a straight line.
  • the drive for the transmission medium can for example also be designed as a pivot drive, which drives in particular directly one of the wheels of the transmission medium.
  • Structurally particularly compact device is formed when the frame has two mutually parallel plate-shaped frame sections, between which the transmission medium is arranged.
  • the two frame sections are used for storage of the transmission medium and can therefore be designed with a relatively small wall thickness. This results in a particularly compact design of the frame in the region of the frame sections in the direction of extension of the axes of the wheels of the transmission medium.
  • the transmission medium has, in particular, a belt drive or a rod connecting the wheels and pivotally mounted in the wheels or a set of gears.
  • a belt in particular a toothed belt, steel belt, chain or the like wraps around the wheels of the belt drive.
  • the transmission medium on two wheels which are connected by means of the rod as part of the transmission medium or with a common, forming part of the transmission medium rack, or, when formed as a gear set, three intermeshing, the transmission medium forming wheels, of which the first and third wheel have the same pivoting direction and in which the bearing element is mounted.
  • This design ensures a clear kinematic relationship between the wheels receiving the bearing element.
  • the arrangement of the bearing of the bearing element in the wheels is selected such that, in the closed position, a connecting line between the pivot axis of the respective wheel and the pivot axis of the bearing element in this wheel at an angle to the straight line connecting the pivot axis of the wheels of 5 to 25 °, preferably 10 to 20 °, in particular 15 °. Consequently, the bearing element and thus the closure part is pivoted over an angle of 5 to 25 °, preferably 10 to 20 °, in particular 15 ° beyond the dead center in the Kochtot Vietnameselage.
  • the respective wheel serving to receive the bearing element can be pivoted through an angle of 50 to 70 °, preferably 55 to 65 °, in particular 61 °. This angle thus corresponds to the angle from the open position to the closed position of the closure part or from the closed position to the open position of the closure part.
  • the bearing element has two plate-shaped bearing element sections and connecting elements connecting them.
  • the bearing element sections are arranged parallel to the frame sections. This plate-shaped design of the bearing element sections ensures only a relatively small extent of these bearing element sections in the direction perpendicular to the direction of movement of the closure part.
  • the frame sections are arranged between the bearing element sections.
  • the frame is thus arranged substantially within the bearing element.
  • the closure part in the region of one end a bearing portion which is connected to the bearing element, and in the region of an opposite end a closure portion for contacting the outlet opening, as well as a bearing portion and the closure portion connecting portion Connecting arm has.
  • the closure part has spring property. This feature makes it possible to press the closure part, after contact with the outlet opening of the nozzle, with a certain bias against the nozzle and thus to allow a secure closure of the outlet opening.
  • the closure part is formed in one piece, thus in particular no different material properties in the region of a closure part surface which in the closed position faces the nozzle end which closes the outlet opening and in the remaining region of the closure part, in particular a bearing region of the closure part.
  • the closure part is preferably made of metal or plastic.
  • a closure part section of the closure part has a base element and a plate received by the base element, the plate having on its side facing away from the base element the closure part surface which serves to close the outlet opening of the nozzle.
  • the base member constitutes the support member for the panel having a different material property than the base member.
  • the plate is elastically deformable, in particular has rubber-elastic properties.
  • the closure part is in particular plate-shaped and has an extension in the axial direction of the wheels, which is smaller than the extension of the bearing element in this direction.
  • This design of the closure part thus contributes to a compact design of the actuating means in the direction perpendicular to the direction of movement of the closure part.
  • the closure part of the open position of the closure member in its closed position considered when the closure member in the open position next to the nozzle and at a level upstream of the outlet opening, based on the flow direction of the substances through the nozzle arranged is, and by means of the actuating means, the closure part is movable from the open position to the closed position, that the leading edge of the closure part surface is moved past the free end of the nozzle.
  • the nozzle is preferably designed to taper in the direction of the nozzle end.
  • the closure part when the closure part is transferred from the open position into the closed position, the closure part does not first contact the nozzle in the region of its free nozzle end with the leading edge, but the leading edge is guided past the nozzle end, whereby the closure part comes into initial contact with the nozzle behind the leading edge , This prevents damage to the leading edge when moving the closure part from the open position to the closed position. It is particularly advantageous if the closure part contacts the free end of the nozzle as extensively as possible when in contact with the nozzle, thus directly closing the outlet opening of the nozzle. By the movement of the closure part, the outlet opening of the nozzle is cleaned.
  • the movement of the closure part relative to the nozzle in the region of the outlet opening is preferably selected such that the closure part with a component of movement perpendicular to the flow direction of the substances is moved through this nozzle with respect to the outlet opening.
  • this movement requires, with high efficiency, that the closure part entrains fabric residues that have accumulated in the area of the outlet opening of the nozzle almost completely to the side, thus freeing the nozzle in the area of the outlet opening of fabric residues.
  • the closure part surface when transferring the closure part from the open position to the closed position and vice versa, is arranged perpendicular to the straight line connecting the wheels and parallel to the pivot axes of the wheels. Consequently, the closure part, from the open position to the closed position and vice versa, moved in parallel.
  • the closure part is arranged perpendicular to the exit axis of the nozzle.
  • the closure part surface is flat, for example.
  • the applicator device having the nozzle is provided with an integrated guide shoe, which moves one below the nozzle Substrate leads.
  • a narrow and thin configuration of the closure part allows a small distance between the outlet opening of the nozzle and the substrate, for example a maximum distance of 5 mm, in particular 3 mm.
  • the kinematic mechanism allows the nozzle to remain in its dosing position when the preliminary part is transferred to its closed position.
  • the inventive device serves for dispensing flowable substances, in particular adhesives, paints, varnishes and release agents for the purpose of application to a substrate.
  • the output of the flowable materials is controlled by a metering valve, which greatly simplifies only with respect to the housing 1 by means of the dashed line and the nozzle 2 mounted in the housing 1 in the FIG. 1 is illustrated.
  • the housing 1 is not shown, but only the nozzle 2.
  • Various types of application of adhesives to a substrate are possible via the metering valve, for example, line, dot, spray, spiral or surface application possible.
  • the nozzle In the region of its free nozzle end 3, the nozzle has an outlet opening 4 for dispensing the substances from the nozzle 2.
  • a closure part 5 Outside the nozzle 2, a closure part 5 is arranged, which can be moved by an adjusting means 6.
  • the closure member 5 is in its open position, as shown in the FIGS. 1 to 4 and FIGS. 7 to 10, the discharge opening 4 is free and closes in the in the FIGS. 5 and 6 illustrated closed position the outlet opening. 4
  • the adjusting means 6 has a frame 7. This frame 7 is screwed to the housing 1 by means of screws 8.
  • the housing 1 is stationary.
  • the frame 7 has a housing 10 of a pneumatic cylinder designed as an actuator 11 and on the side facing away from the housing 1 two mutually parallel plate-shaped frame sections 12.
  • the actuator 11 has a connection 13 for supplying compressed air and a cylinder space 14 assigned in the housing 10 for displaceably receiving a piston 15.
  • the piston 15 is displaceable under the action of compressed air against the force of a spring 16.

Accordingly, a stroke movement of the piston 15 under the action of compressed air causes the belt 20 to be moved counterclockwise by a corresponding distance and the return movement of the piston beyond the action of compressed air and under the action of the spring 16 to return the belt 20 by the corresponding stroke distance of the piston 15.

  • the bearing sections 28 are arranged parallel to the frame sections 23, furthermore, the frame sections 23 are arranged between the bearing element sections 28.
  • the two frame sections 12 receive the transmission medium 17 or the wheels 18, 19 with little axial play and the respective bearing element section 28 is arranged at a small distance from the associated frame section 12. This is in particular the representation of the FIG. 2 to see that illustrates the adjusting means 6 in the direction of the bearing axes 21 is designed very compact.
  • the closure part 5 has in the region of one end a bearing portion 30, which is connected to the bearing element 26 in the region of the wheel 19 adjacent connecting elements 29. In the region of the opposite end, the closure part 5 has a closure part section 31 for contacting the outlet opening 4. Furthermore, the closure part 5 has a bearing section 30 and the closure portion 31 connecting connecting arm 32.
  • the closure member 5 is plate-shaped and has an extension in the axial direction of the wheels, thus in extension of the bearing axes 21, which is less than the extension of the bearing element 26 in this direction.
