Definitions

  • the invention relates to a device for the simultaneous and metered dispensing of viscous masterbatches, in particular fillers or putty, and hardener pastes made of canshaped containers containing a displaceable press lid and provided with closable outflow openings on the bottom, with or without a support bracket attached to the container wall, consisting of a designed as a U-shaped support bracket, the plate-like centering brackets for the can-shaped container and a squeezing device with simultaneously operable piston rods with end-arranged piston plates displaceable in the interior of the can-shaped container in the direction of the centering bracket, the containers having a cross-sectional shape and dimensions that correspond to those of the centering bracket, which are arranged on the lower bracket leg of the support frame.
  • a bracket for such a device is known from JT-A-384936.
  • a fixed dispenser is known from US-A-3 957 176.
  • a hand-held dispenser for two-component materials with cartridges containing disposable material, disposable mixing head and disposable connecting lines is known from DE-A-2 537 022.
  • This dispenser is comprised of a pair of cartridge receiving sleeves that are open at opposite ends to receive the material containing and dispensing cartridges through one end, the other end of the cartridge extending through the opposite end of the sleeve, and a cartridge piston in the area of one Liner end is arranged by a piston assembly with a pair of piston heads, which are provided at the ends of a pair of piston rods and connected to each other for simultaneous movement and a base assembly for fastening the double piston assembly to bring the piston heads to the cartridge pistons in the working position, by a mixing head attachment and holder assembly for releasably attaching and holding the mixing head, wherein the two cartridges, the mixing head and the connecting lines for metering, mixing and dispensing the two-component materials are connected to the dispenser and can be removed after use for re-use Use of the device with replacement cartridges,
  • the known hand-held dispenser for two-component materials has, in particular, an embodiment according to which two pipe socket-like receiving chambers for the cartridges to be used are provided in a holder, and after the cartridges have been inserted into these receiving chambers, they are hinged to a carrier plate Brackets are pivoted so that the cartridges are in the feed path of the plunger.
  • the outlet openings of the cartridges or of the holders receiving the cartridges are connected via pipes to an output nozzle which is designed as a disposable nozzle and is replaced by a new nozzle after use.
  • a disadvantage of this known dispensing device is that after the cartridges have been emptied, the mixing heads used are filled with fillers and hardener paste deposits, which crust or harden when the device is not used for a long time, so that the mixing head must then be replaced.
  • the lines for forwarding the mass to be pressed are not arranged on the support frame, but rather on the opening projection of the container itself, so that the problem of sealing between the support frame and container does not arise. Likewise, the problem does not arise here if the containers release their extrusion mass directly without the interposition of another line.
  • a device for holding a container with the filling device provided on the bottom part thereof for dispensing the contents of the container can be found in the aforementioned US Pat. No. 3,957,176.
  • This known device has a stand frame with two mutually parallel support rods as a support for the container. Lateral stops limit the container placed in this way, which is secured in position by means of a locking screw. The contents of the container are dispensed using compressed air. For this reason, the lid part of the container has a firm and airtight connection for the required pressure line, while the bottom part of the container is provided with an opening designed as a threaded connection as an outlet opening.
  • a disadvantage of this known device is that the filling device must be connected to the container to be emptied in the region of its outlet opening in the base part. Since the filling device is attached to the bottom part of the container, aligning and centering the container on a filling device fixedly attached to the support frame is not necessary, since this is part of the container. According to this, the filling device used is not an integral part of the device carrying the container, but rather represents a special part which has to be placed on the peripheral edge delimiting the outflow opening when the container is started up. Viscous fillers can only be pressed out of a container or cartridge using high pressure. The larger the size of the container, the greater the pressure to be applied.
  • a filling device which is only placed on the edge delimiting the outflow opening, can easily leak in the connection area, in particular when high pressures have to be used to squeeze out the contents of the container. If, on the other hand, the filling device is attached by means of a screw thread to the bottom part of the container, then a relatively large amount of work is required to make such a container ready for operation.
  • a device for receiving three cartridges is known, with which the contents of the three cartridges can be pressed out simultaneously.
  • This known device comprises a support frame with centering brackets for the cartridges containing the masses to be dispensed and a squeezing device with simultaneously operable piston rods with piston plates arranged at the ends and displaceable in the interior of the cartridges in the direction of the centering bracket, the cartridges to be used in this device having a cross-sectional shape and dimensions have that correspond to those of the centering brackets.
  • Disadvantages of this device are that the device can only be operated by hand and that after the end of the squeezing process, mass still flows out of the cartridges, whereby this afterflow can only be stopped when the pressure of the press pistons exerted on the mass is released by pulling back the main piston rod .
  • US-A-4033480 describes a device with which two different media can be dispensed simultaneously from two separate containers.
  • This device consists of a base plate with two openings, which are connected to exhaust valves.
  • Two containers are arranged on the base plate and are provided with an outlet opening on the base.
  • the bottoms of the two containers have offsets located on the outside, in such a way that these offsets engage in the holes in the base plate in the case of containers arranged on the base plate.
  • the bracket-like locking devices provided in this device not only serve to secure the position of the two containers on the base plate, but also to hold the lid parts of the two containers on the containers themselves, since the entire device is operated by means of compressed air.
  • a piston plate which can be acted upon by compressed air, is arranged in each container above the mass in the container, so that the masses can be pressed out of the two containers after the outflow valves have been opened.
  • a disadvantage of this device is that the piston plates are actuated in the interior of the two containers by means of compressed air. It cannot be ruled out that compressed air flows into the space between the piston plate and the container wall, since a complete seal in the piston plate edge area to the inner wall surface of each container is problematic. When emptying the container down to the last mass residues, it is therefore unavoidable that these residues are pressed out of the opened outlet valves with a relatively high pressure, and the mass flowing out can thus splash.
  • the two containers on their base plates are centered only by the cranks.
  • Each container is simply placed on its base plate and the container has to be moved until the offset provided in the area of the bottom outlet opening of the container engages in the through-hole in the base plate.
  • the containers used in this device have offsets formed on the outside of the container base plates in the region of the container outlet openings on the bottom. The offset therefore does not lie in the plane formed by the base plate of each container. The result of this is that containers designed in this way cannot easily be placed vertically on a flat surface on their bottom side. The direct stacking of such trained containers is also difficult.
  • the lid parts of the container are removable and must be held firmly on the container bodies due to the use of compressed air, which is done by means of the bracket-like locking devices provided.
  • the outlet valves for the two containers are arranged at a relatively large distance from one another, so that the masses from the two containers are not pressed out close to one another.
  • the fact that the ejection pistons are acted upon by gas pressure does fix the containers by forwarding the pressing force of the pressing pistons to the container bottoms, the container bottoms being pressed against the base plates by the pressing force, but the gas pressure forces acting on the container lids must exceed Screw buttons and clamps are supported on the support frame and caught.
  • the container lids must not be positively connected to the containers, since otherwise the gas forces acting on the container lid would not allow the pressing forces serving for the required fixation to take effect, but must be done using the screw buttons and clamping brackets attached to the support frame are pressed gas-tight against the containers. After this, a sealing screw connection of the container lid via a clamp is always required.
  • the invention seeks to remedy this.
  • the invention solves the problem of creating a device with which not only fillers and hardener pastes can be dispensed simultaneously and in a metered manner, but also with which clean masses, without receiving crusty filler particles or other contaminants, are integrated from the corresponding containers via one another Removal openings can be dispensed, an overdosing of the masses to be dispensed with being avoided by the container contents flowing in again.
  • the container is kept centered in the support frame by means of the base plate, so that the piston plate of the working cylinder can act directly on the mass in the interior of the container.
  • the piston plate or, if a separate press cover is arranged in the interior of the container this press cover is pressed in the direction of the container outlet opening, so that the container content emerges from the opening of the pipe socket provided on the bottom of the device and at the same time in the provided on the bottom Filling head is pressed, the respective quantities to be dispensed can be adjusted in the filling device by corresponding actuation of the shut-off valve.
  • the container for the trunk is provided in the region of its base with a centering device designed to be offset on the outside, makes it possible for the piston plate of the working cylinder in the interior of the container to be moved onto the container base part, so that the container contents up to the last remnant can be pressed out of the container.
  • the base plate centering the container in the device is formed in the area of its through-hole opposite the outlet opening of the container so that the offset on the outside of the container bottom can be inserted into the opening of the through-hole, so that the container lies flat on the base plate with its base part.
  • the circumferential edge of the container which has at least a height that corresponds to the height of the offset in the region of the outflow opening of the container, laterally overlaps the base plate, so that a firm fit of the container is ensured in the device, which is particularly advantageous if in the container has only a few regular aces.
  • the base plate is designed accordingly, so that the container is always centered on the base plate.
  • the device designed according to the invention is reusable. If a can-shaped container is emptied, only a new full container is inserted into the device and the contents of the container can be dispensed in the desired quantity by means of the working cylinder. Because the container is aligned with the design of the device, only the containers specially designed for this purpose can be used for the device designed according to the invention.
  • the advantages achieved by the invention are essentially to be seen in the fact that, at the same time, the master batch and hardener composition are pressed out of two containers in metered quantities in such a way that the quantities dispensed lie close together on a base.
  • the two containers which hold the masses are matched to one another in their diameters in such a way that parallel dosing, i.e. Output of the masses in the respective required ratios to one another is possible.
  • the container for the hardener paste can be squeezed out in the simplest manner, which is achieved by means of the control bracket which is connected to the working cylinder.
  • the can-shaped container used for the hardening paste can be designed in the same way as the container for the parent mass.
  • the holder for the container with the hardening paste can also be designed in accordance with the base plate for the container with the master mass and has a centering device.
  • the hardener paste is dispensed by means of the control bracket which is positively controlled by the working cylinder for the container with the parent mass.
  • a device for dispensing the contents of can-shaped containers consists of a support frame 5, which is designed like a bow or frame and is designed to accommodate two containers 100 and 200.
  • the container 100 is used to hold a base mass, such as filler or putty, while the container 200 holds the hardening paste.
  • the support frame 5 has two webs 11, 12 which are arranged at a distance from one another and are connected to one another via a vertical web 13. However, there is also the possibility of connecting the two webs 11, 12 to one another via a connecting plate. One of the two webs serves to receive a working cylinder 20, while the other web 12 is provided as a base plate 30 for the containers 100 and 200 to be emptied.
  • the working cylinder 20 operated by means of compressed air, compressed gas, hydraulically or by electric motor or by hand is arranged on the upper web 11 of the support frame 5 in the embodiment shown in FIGS. 1 and 2.
  • the working cylinder 20 is arranged below the upper web 11, so that the working cylinder 20 comes to lie between the two webs 11, 12.

  • Recesses 418 are formed on the side surfaces 416, 417, in which bearing journals can be inserted, about which the locking bolt 411 can be pivoted.
  • the pivoting range of the locking bolt 411 is limited by an upper stop 419 and a lower stop 420. Both stops 419, 420 are arranged on the side surfaces 416, for example they can be formed by pins projecting beyond the plane of the side surface 416.
  • the locking bolt 4 has a U-shaped cross section and consists of a longitudinal web 431, on the end section side of which a transverse web 434, 435 is arranged.
  • the transverse webs 434, 435 have openings 436, 437 into which the bearing journals mounted in the recesses 418 can be inserted.
  • a connecting member 438 for a handle 421 is also provided on the crosspiece 434.
  • closure connectors 413, 414 associated with the dispensing openings 423, 426 are each arranged with a recess 432, 433 open to the dispensing openings 423, 426.
  • sealing strips 441, 442 can be arranged (FIG. 9), which extend between the chamfer 439 and the groove 429 or the groove 429 and the groove 430.
  • These sealing strips 441, 442 are preferably designed in such a way that they enable the masses emerging from the dispensing openings 423, 426 to be sheared off without residues of the dispensed mass remaining after the metering process has ended.
  • the groove 429 serves to prevent the hardening paste emerging from the discharge opening 423 from mixing with the parent compound emerging from the discharge opening 426 when the filling head 410 is closed.
  • the groove 430 formed in the end face 415 also serves to receive hardening paste emerging from the discharge opening 423.
  • the filling head 410 joint filling of master batches and hardening pastes located in separate containers 100, 200 is possible.
  • the dispensing openings 423, 426 which are located in the immediate vicinity of one another, make it possible to apply the hardening paste and the master paste even on small spatulas without loss of material.
  • the locking latch 411 can, however, also be designed differently. So it is possible to provide the locking latch with sealing body inserts, via which the dispensing openings can be closed.
  • stirrup legs 302, 303 of the control stirrup 300 are designed to be variable in their lengths, so that a perfect pressing out of the contents of the two containers 100, 200 is ensured.
  • This length adjustment of the stirrup legs 302, 303 can be done by a telescopic design of each stirrup leg.
  • the support frame 5 of the overall device is designed such that two containers or cartridges 100 and 200 are arranged side by side in this.
  • the larger container 100 then receives the filler or putty from the two containers 100, 200, weh rend the other, designated 200 container, for example, a hardening substance that is required for a quick hardening of the filler or putty.
  • the device shown in FIGS. 13 to 15 is also provided with a strand cutting device 500.
  • This strand cutting device 500 consists of a plate-shaped slide 521a, which has a U-shaped profile with the legs 522 and 523, which are connected to one another via a web 524, to which the working cylinder 525 for moving the slide 520 is connected.
  • the distance between the two legs 522, 523 of the slide 521 a corresponds to the distance between the discharge openings 502, 502 a of the two associated drainage nozzles.
  • the width dimensioning of each leg 522 or 523 is such that when the slide 521 is lowered, each of the two dispensing openings 502, 502a is completely and in particular airtight.
  • the bottom edges of the legs 522, 523 of the plate-shaped slider 521 are designed in the manner of knives as cutting edges 522a and 523a, so that even with a strand cutting device designed in this way, a perfect severing of the mass strand is guaranteed to end a removal process.
  • the strand cutting device 500 consists of a comb-shaped slide plate 621 with a number of these plate-shaped tines 622, 623 and 624 corresponding to the number of discharge openings of the emptying nozzle (FIG. 16).
  • the number of these plate-shaped tines 622 to 624 depends on the number of cartridges accommodated in the support frame 5.
  • Each tine 622 to 624 is designed and dimensioned such that the corresponding outlet openings are sealed airtight when the slide 621 is in the lowered position.
  • the lower edges of the comb-like slide 621 are also knife-shaped as cutting edges 622a, 623a and 624a, so that the removal process can be interrupted simultaneously for all the containers accommodated in the support frame 5. In this case, too, it is possible to cut off the strands properly.
  • a device designed in accordance with FIGS. 13 to 16 ensures that regardless of the degree of viscosity of the contents of the containers when filling to complete the filling process, a flash-like cutting of the mass strand from the masses still in the containers is possible without a strand section of the filling mass hangs out of the emptying nozzle and can harden through air supply, so that the emptying nozzle must first be freed from the hardened mass before the contents of the container can be removed again.
  • This type of cleaning process does not apply to this device, since at the same time the removal opening is hermetically sealed after the mass strand has been cut off, so that when the contents of the container are removed again, the original consistency of the mass is available and does not remove a hardened, drop-like section of the strand must become.
  • a strand cutting device with a comb-shaped slide enables the outlet openings of several emptying nozzles to be closed at the same time and without problems if the device is designed such that several containers or cartridges filled with highly viscous masses have to be accommodated, the contents of which, for example, must be accommodated Mixing purposes or at a desired increase in the filling speed should be subjected to an emptying process at the same time.
  • an adapter 700 is arranged on the support frame 5 according to FIG. 12, which is provided with a through-hole 701 which is arranged centrally or eccentrically according to the arrangement of the outlet opening 106 can be.
  • This through-hole 701 connects the outflow opening 106 of the container 100 or 200 to the inlet opening of the filling device 400, for which purpose the upper opening 702 of the through-hole 701 is adapted to the respective size and dimension of the outflow opening 106 of the container 100 or 200, while the lower opening 703 of the Through hole 701 corresponds to the size and dimension of the inlet opening of the filling device 400.
  • the adapter 700 matched to these outlet openings is used in each case.
