"Adhesive Applicator"

The invention "relates to an adhesive applicator with the delivery of the adhesive by means of compressed air via a riser pipe out of an original adhesive container and via a delivery line to a valve, in particular a manually operated valve. Such a mechanical-pneumatic one Applicator and conveyor for liquid products is preferably used for one-component gyanacrylate adhesives as well as for anaerobic one-component adhesives.

In the aforementioned apparatus, the adhesive is applied, e.g. from a compressed air network or from an electrical The pressure generated by the pump is applied and conveyed to a valve, from which the adhesive is manually operated, is to be ejected electromechanically or electropneumatically. On some devices, the adhesive can be attached to the Original containers are placed in a pressure vessel in such a way that the adhesive comes out when pressure is applied the adhesive container is to be conveyed to a valve via a riser pipe. The known apparatus of this type are expensive and complicated. Another disadvantage is the lack of security against tipping over; when tipping over can namely Adhesive leak and glue the pressure vessel.

Adhesive conveyors are already on the market in which the adhesive does not use compressed air but directly with the help of a pump, especially

a peristaltic pump or diaphragm pump. However, these conveyors are for all of the types of adhesive are unsuitable for which the Risk of polymerizing (hardening) at capillary sites consists.

The invention is based on the object of creating an inexpensive hand-held device for applying adhesive, which without electrical connection, i.e. by means of simple manual operation, can be used as well as during operation and transport is easy to handle and, in particular, can also be tilted. The solution according to the invention is in the adhesive application apparatus with promotion of the Adhesive by means of compressed air through a riser pipe from an original adhesive container to a valve characterized by an over the device with the interior of the in a dimensionally stable with respect to the working pressure housing Hand-operated air pump connected to the original container with compressed air supply to the adhesive container by means of a sealing collar that elastically encloses the riser pipe between the riser pipe and a formed and in the opposite direction for the adhesive blocking gap.

By using a hand-operated air pump and the sealing sleeve surrounding the riser pipe to operate the device according to the invention independently of a supply connection as a hand-held device and at the same time easy to transport without worrying about tipping. There is also the original adhesive container to put in a dimensionally stable housing and directly to the generated by the hand-operated air pump Pressure is to be applied, requires the invention

K The z. B. trainees as a hand-operated diaphragm pump

The air pump can be coupled directly or indirectly via a hose or some other line to the device receiving the adhesive container. A bellows, a small piston pump or the like can also be used instead of a diaphragm air pump. There

ϊ i ) the air pressure is to be generated by manual operation,

j | 10 only low working pressures of 0.1 to 1 bar arise,

in such a way that pressure reducing devices are known from commercially available devices of the type mentioned at the beginning are not required.

For a number of adhesives, e.g. those based on cyanoacrylate, hardening or polymerizing occurs already under the influence of humidity. In the case of known devices, special precautionary measures must therefore be taken and a special material selection can be made to prevent premature polymerizing within of the device that would render the device unusable. In the apparatus according to the invention these problems can preferably be mastered by replacing the air pump in the suction side hygroscopic material, in particular a salt tablet, is arranged. Elaborate filters and the like are therefore not required.

According to a further invention, the dimensionally stable housing adapted to the contour of the original adhesive container be designed as a stand sleeve with union nut.

The dimensionally stable housing ensures that the adhesive container does not deform when pressure is applied can because it rests on the inside walls of the housing and on the union nut practically on all sides.

An essential task, especially of the union nut, is to lift the adhesive container to exclude within the stand sleeve and a corresponding deformation of the container base. By the feast Union nut placed on the stand sleeve is achieved so that the distance between the lower end of the riser pipe and the bottom of the adhesive container remains constant during the entire emptying process.

The amount of adhesive remaining in the adhesive container can easily be checked if that Container and especially the stand sleeve made of transparent material, preferably also made of plastic, will be produced.

Furthermore, a screw head is screwed onto the original container, the height of which is preferably a riser pipe Via a union nut with a seal on the screw head, with a built-in, coming from the air pump Air more permeable in the direction of the interior of the adhesive container, more elastically encompassing the riser pipe Includes sealing sleeve and a connection for the air pump.

This sealing collar is also designed so that it is also a seal between the adhesive container and Screw head is.

Further details of the invention are given on the basis of the schematic representation of an exemplary embodiment explained.

With the aid of the adhesive application device according to the accompanying drawing, adhesive 1 can be removed from an original container 2 via a riser 3 and a delivery line 4 to a manually operated valve 5 Adhesive outlet 6 are promoted. Essential

'Features of the apparatus of the invention are one

a hand-operated air pump designated as a whole with 7, a sealing sleeve 8 surrounding the riser pipe 3 and a housing which is adapted to the shape of the original container 2 on the inside and which consists of a stand sleeve 9 and a cover with union nut 10 consists. In the exemplary embodiment, the air pump 7 is a diaphragm pump with membrane 11, an inlet check valve and an outlet check valve 13 and preferably - in the case of processing adhesive that has hardened prematurely due to moisture - one in the suction side the salt tablet 14 inserted into the air pump 7.

f When this - commercially available - tablet by

Discoloration indicates a certain level of moisture saturation, it must be replaced.

In the exemplary embodiment, the air pump 7 is directly over the adhesive container 2 with a screw head 15 coupled to the stand sleeve 9 with union nut 10. A compressed air inlet channel leads inside the screw head 15 16 along the riser pipe 3 through one between the sealing collar 8 and the riser pipe 3 Gap formed as a result of the air pressure in the interior of the original adhesive container 2.

It is above all the sealing collar 8, through which the tilting and transport security of the invention Apparatus is reached. As the diht cuff 8 rests elastically on the riser pipe 3, air in the direction of arrow 17 can - because of the shape of the sleeve penetrate from the compressed air inlet channel 16 into the interior of the Ofiginalgebindes 2, but the reverse can Adhesive 1, even if the device is tilted or upside down, does not move from the container 2 into the compressed air inlet duct 16 penetrate because to the sealing sleeve 8 flowing adhesive the sleeve because of its shape squeezes and thus closes the passage in question.
