The invention relates to a mounting device for fastening a component, such as in particular a fixture or bracket, at a defined location.
To transport products in a packaging, it is often necessary to keep the product in the package so that it cannot slip. For this purpose, inserts are known, which often consist of a foam or cardboard and are adapted to the product in such a way that a product placed in the packaging is held within the packaging in such a way that it cannot slip.
It is also known to stick lashing eyes/lugs and straps to the inside of the blister in a container, such as a blister, in order to hold the product in the blister in a precise position.
Such solutions are either material-intensive or labour-intensive in placing the holding devices inside the packaging and in securely positioning and holding the product in the packaging.
The invention is therefore based on the object of providing a mounting device with which, individually and reproducibly, even differently shaped components can be securely held in a packaging.
This object is solved with a mounting device as described herein.
The object is also solved with a method for the validatable fastening of a component, such as in particular a fixture or bracket at a defined location, with the characteristics described herein.
Advantageous further embodiments are also described.
The holder or receptacle ensures that the component, and in particular a fixture or bracket, can be held precisely in a defined position relative to the base body. The suction device makes it possible to hold the base body with the holder at a defined location. This is usually a predetermined position within a package. Finally, the pressing device makes it possible to press the component held in the holder to the defined location in order to hold the component there in a positive or non-positive manner and, in particular, to bond it.
The mounting device thus enables the user to easily and precisely attach a fixture or bracket, for example, to a specific location and fasten it there. Especially for the transport of easily damageable products within an outer packaging, the mounting device facilitates the holding of the product within the packaging, for example with mounting straps that are arranged and tensioned in a defined manner within the packaging. This ensures that the products are not damaged during transport even if the packaging is not handled properly.
The mounting device can be used to fix components at any location. However, it is advantageous, if the defined location is within a cavity of a packaging. Even if access is difficult within a packaging, the mounting device enables the defined attachment of fixtures or brackets.
In order to be able to arrange the base body and thus also the component held in the holder or the receptacle of the base body in a defined position relative to a wall, for example a packaging or blister, it is suggested that at least one height stop is arranged on the base body. This height stop can be a rod that can be moved relative to the base body, which can preferably be precisely adjusted and fixed in its position relative to the base body by means of a scale provided on the rod or on the base body. This makes it possible to feel via the stop when manually operating the mounting device whether the base body and thus also the component is positioned at the defined location.
Especially when special distances of the height stop relative to the base body are used repeatedly, it is advantageous, if the height stop has a hook to define at least one hook position of the height stop relative to the base body. Preferably, the height stop has several spaced hook positions to facilitate the positioning of the base body within a packaging.
In order to fasten the component at a defined location, it is particularly advantageous when fastening by means of an adhesive, if the holder or receptacle has a pressure element to hold the component in the holder or receptacle with a defined force. This results in the component being held securely in the holder or receptacle, but can be removed from the holder or receptacle when a defined release force is applied, such as in particular a pull on the component. The component can thus be held in the holder or receptacle with the base body, for example, and guided to the defined location and held there until an adhesive between the component and the defined location sets, so that when the base body is pulled off with the holder or receptacle from the component, the component remains at the defined location. An interference or press fit can, for example, serve as a retaining element for retaining the component in the holder or receptacle with a defined force. However, e.g. a flexibly mounted pressure element or a spring mechanism, such as a ball thrust piece in the component holder or receptacle, for example, is advantageous for holding the component in the holder or receptacle.
Cumulatively or alternatively, it is suggested that the holder or receptacle has a suction element to hold the component in the holder or receptacle with a defined force. The suction element can be a passive suction element, such as a suction cup, and it can also be an active suction element, such as a suction device that can be connected to low pressure conditions.
Especially for the use of differently shaped components or components of different sizes, it is advantageous, if the holder or receptacle has a holder area whose dimensions can be adjusted, preferably with a hook. If, for example, the height, width and/or depth of the holder or receptacle can be adjusted, this makes adjustment to different components easier. A scale can be provided for the dimensioning of the holder area.
The mounting device can be connected to a robot or an electronic positioning device. For manual positioning of components, however, it is particularly advantageous, if the device is designed as light as possible. Therefore, it is suggested that the holder or receptacle and/or the base body are made of plastic or aluminium. Polyoxymethylene, for example, is a suitable material for the holder or receptacle.
The suction device, which serves to hold the component held in the holder or receptacle at the defined location, can be any suction cup. However, it is advantageous, if this suction device has at least one flat vacuum suction cup.
It is particularly advantageous, if the suction device has several flat vacuum suction cups, whose position relative to the base body can be adjusted in defined positions, preferably by hooks. This enables adjustment to different surface geometries by positioning the suction device relative to the base body at a defined height, width and/or depth.
Especially for the fastening of a component within a packaging which is difficult to access, it is advantageous, if the suction device has a flat vacuum suction cup which is connected to the base body via a joint. Preferably, the suction device has several such joints with flat vacuum suction cups.
Such a suction device can be operated hydraulically or mechanically. However, it is particularly advantageous, if the suction and/or pressing device can be operated pneumatically. This is usually realised by a pneumatic pressure cylinder. The suction and/or pressing device is preferably connected to a connection point for at least one suction and/or pressure line.
In order to be able to run the operations on the mounting device under electronic control, it is suggested that the mounting device has a controller. This enables, for example, the suction and/or pressing device to communicate with the controller in order to automatically adjust the pressure and/or duration. Particularly in the case of an adhesive connection, this can ensure that the component is held in place for a sufficiently long time and, in particular, with sufficient pressure at the defined location so that the adhesive connection is sufficiently strong before the holder or receptacle is pulled off the component.
It is advantageous, if the mounting device has at least one trigger device that is connected to the controller. In this way, the individual processes can be triggered one after the other or several processes and in particular all processes for fastening the component at the defined location can be started by the trigger device. For example, with a trigger guard, a lever, a pistol trigger or a foot switch, the entire process or even or partial steps can be activated via the controller.
A particularly advantageous embodiment is that the trigger device has a contact switch. This makes it possible, for example, to start the process via a sensor or via a mechanical trigger when the component is pressed against a surface at the defined location.
Especially if the base body is connected to a supply area, for example via electrical and/or pneumatic lines, the controller can be arranged at the supply area. However, it is advantageous, if the controller forms a mobile unit with the base body. This allows the controller to trigger and monitor the process steps directly on the base body.
Regardless of the controller's arrangement, it is advantageous, if the controller has a display. It can, for example, show the current holding time still required or the current process step.
In order to make the mounting device as light and mobile as possible, it is suggested that the mounting device for the suction device and the pressing device has only one pressure line as supply line. This pressure line can be under overpressure or underpressure in order to provide the suction pressure for the suction device and, if necessary, also an overpressure via a valve control.
Mobility can also be improved by connecting the suction device and/or the pressing device to a portable pressure vessel. This pressure vessel can also be permanently connected to the base body to provide a compact mobile unit.
The component can already be provided with an adhesive, which is activated by peeling off a film, for example. However, the mounting device can also have an applicator device to apply an adhesive to the component or the defined location.
For this purpose, it is suggested that the applicator device be equipped with a distribution mechanism, such as a nozzle, a spatula or a pressing surface, in order to apply the adhesive either as a defined bead or over a large area.
For the application of an adhesive, it is advantageous, if the applicator device is positioned next to the holder or receptacle.
It can be operated hydraulically for the transport of an adhesive as a bead or, especially for a spray applicator, also pneumatically.
The mounting device may have a handle to allow manual operation in the simplest possible way. This handle may also have triggering devices and/or switches to activate individual process steps or the entire sequence.
A particularly compact design of the mounting device provides that it is designed as a mobile portable unit with a pressure generator. The energy for the pressure generator can be made available via a power supply line or via an over- or underpressure line.
A further increase in mobility is achieved by the fact that the mounting device is designed as a mobile portable unit with a mobile power supply, such as a battery or an accumulator.
In terms of the process, it is particularly advantageous, if the base body is first fixed in place with the suction device, then the holder or receptacle with the component is moved to the defined location with a pneumatic device, then the holder or receptacle is pulled off the component, after a defined time the pressure of the pressing device on the component is released and then the suction pressure of the suction device is released.
It is particularly advantageous, if the suction pressure of the suction device is automatically released in a time-controlled manner. Alternatively, the suction pressure can also be deactivated manually.
It is advantageous, if the suction pressure of the suction device is at least strong enough to hold the base body at the defined location even at maximum pressure of the pressing device. By adjusting the pressures on the suction device of the pressing device, contact pressure and contact time can be set in a defined manner. This is preferably done via a controller.
In order to ensure that the component is also fastened in the correct place, it is suggested that the base body is positioned at the defined location with a height stop. This facilitates manual operation in particular.
The mounting device and the inventive method are described in more detail below using an exemplary embodiment. It shows
The packaging 4 shown in
For this purpose, the mounting device 1 has a base body 8 with a holder or receptacle 9 for the component 2.
A suction device 10 serves to hold the component 2 held in the holder or receptacle 9 with the entire mounting device 1 at the defined location 3 of the packaging 4.
A pressing device 11 serves to press the component 2 held in the holder or receptacle 9 to the defined location 3.
In order to vary the position of the base body 8 to the upper edge 13, the height stop 12 has a hook 14, so that a position of the height stop 12 relative to the base body 8 can be noticeably determined.
The component 2 must be held in the holder or receptacle 9 to guide it to the defined location 3 on the packaging 4, and it must be detachable from the base body 8 to remain adhered to the packaging 4 when the mounting device 1 is detached from the packaging 4. For this purpose, the holder or receptacle 9 has a pressure element 15, which is designed as a fit to hold the component 2 with a defined force in the holder or receptacle 9.
In addition, a suction element 16 is provided, which holds component 2 in holder 9 with a suction force.
The width of the holder 9 can be adjusted by means of a sliding element which is hooked to the base body 1, so that the width of a holding area 18 for component 2 can be adjusted.
Since the entire mounting device should be stable and easy to handle, its individual parts are essentially made of plastic or aluminium.
The suction device 10 consists of four flat vacuum suction cups 19, 20, 21 and 22, whose position relative to the base body 8 can be adjusted in defined positions by means of spacers 23 and 24.
The entire suction device 10 or the individual flat vacuum suction cups 19, 20, 21 and 22 can also be connected to the base body 8 via a joint (not shown).
The flat vacuum suction cups 19, 20, 21 and 22 each have pneumatic connections 25, 26, 27 and 28, which are connected to an underpressure device (not shown) via lines 29. This means that the suction device can be operated pneumatically.
The base body 8 of the mounting device 1 has a handle 30 in which a controller 31 is located, which is in connection with the suction device 10 and the pressing device 11 to adjust pressure and duration at the suction device and the pressing device.
A contact switch 32 is used to activate a trigger device 33, which is connected to the controller 31. The result is that the controller 31 and the base body 8 form a mobile unit 34 which is connected to pneumatic devices (not shown) via the line 29 and is easily portable, e.g. in cavity 7 of a packaging 4, and can be easily positioned at a defined location.
A display 35 shows on the handle 30 the status of the mounting device 1 set by the controller 31.
In the embodiment shown in
An embodiment, also not shown, provides that the suction device 10 and/or the pressing device 11 are connected to a portable pressure vessel (not shown).
In the embodiment shown according to
It is advantageous, if this applicator device can be operated pneumatically.
When using such a mounting device 1, component 2 is first positioned in holder or receptacle 9 and held there. Then an adhesive 36 is applied to component 2. Then the base body 8 is positioned with component 2 at the defined location 3 and held precisely in place with the suction device. Then the holder or receptacle 9 with component 2 is moved relative to the base body to the defined location 3. Afterwards, the component 2 located in the holder 9 is moved by means of a pneumatic device (not shown) relative to the base body to the defined location 3 so that the adhesive touches the packaging 4. Then, the holder 9 is pulled off component 2 and the base body 8 is removed from component 2.
The suction device 10 makes it possible to fix the base body 8 at location 3 and the pressing device 11 makes it possible to press the component 2 at location 3 until the adhesive 36 sets. After the holder 9 has already been pulled off the component 2, the pressure of the pressing device 11 on the component can be released after a defined time period and as an ultimate step the suction pressure of the suction device 10 is released.
The entire operation can be automatically controlled by the Controller 31. Preferably, care is taken to ensure that the suction pressure of the suction device 10 is at least strong enough to keep the base body 8 at the defined position even at maximum pressure of the pressing device 11.
