With reference to the figures, an embodiment of an apparatus for
Installation of a corner cabinet described.
The mounting device according to the invention comprises a base frame 1 , which consists of three parts 1a . 1b and 1c is composed. The two parts 1a and 1b each carrying a press frame. The part bears more exactly 1a of the base frame 1 a first press frame 2 and the part 1c of the base frame 1 a second press frame 3 , The press frames 2 . 3 are linear on the parts on rails 1a . 1b of the base frame displaceable. How out 1 it can be seen, the two parts 1a and 1b arranged at an angle α to each other. In the present embodiment, the angle α is exactly 90 °. By in dashed lines in 1 drawn extensions of the base frame 1 a working area W is defined in which the assembly of a corner cabinet takes place by means of the mounting device according to the invention.
The press frames 2 . 3 are frame structures, which each have a support element 4 respectively. 5 exhibit. The support elements 4 . 5 For example, are designed as wood panels and the upright frame of the press frames 2 . 3 arranged. As in 1 shown, serve the support elements 4 . 5 as contact surfaces for a first side wall A and a second side wall B of the corner cupboard. At the bottom of the support elements 4 . 5 is in each case a lower support rail 6 . 7 arranged. The lower support rails 6 . 7 serve to abut the lower edge of the side walls A, B.
The press frames 2 . 3 are each of non-illustrated drive means in the linear direction X and Y perpendicular to the support elements 4 respectively. 5 driven. In the 1 to 3 the drive devices are not shown in detail. It should be noted, however, that the drive means may comprise, for example, ballscrews and servomotors. Due to the movability of the press frames 2 . 3 ensures that corner cabinets with variable widths can be mounted and pressed on the mounting device according to the invention. It should also be noted that alternative drives can also be, for example, pneumatic or hydraulic cylinders or a rack drive or a linear motor.
How out 1 it can be seen, the side walls A, B on the support elements 4 . 5 created. To prevent the side walls A, B from the support elements 4 . 5 fall over, can in the support elements 4 . 5 Vacuum suckers are provided which suck the applied side walls A, B. The side walls A, B are doing so to the support elements 4 . 5 Put that on its vertical front edge on a vertical stop 8th . 9 is applied. Thus, the side walls A, B are applied to three components, namely the sheet-like support elements 4 . 5 , the lower support rails 6 . 7 and the vertical stops 8th . 9 , It should be noted that a loading of the mounting device according to the invention can be done both manually and automatically, for example by means of a robot.
As in further 1 are shown at the bottom of the press frames 2 . 3 pneumatic cylinder 10 . 11 arranged. Exactly on the first press frame 2 a first pneumatic cylinder 10 arranged and on the second press frame 3 a second pneumatic cylinder 11 arranged. Next are at the press frames 2 . 3 one lower side stop each 12 respectively. 13 arranged, which form a vertical rear stop for the rear vertical edge of the side walls A, B in the operation of the device. The lower side stops 12 . 13 are here by means of the pneumatic cylinder 10 . 11 actuated.
Adjacent to the lower side stops 12 . 13 are rear floor stops 20 . 21 arranged (cf. 1 ), which form a stop for a lower cabinet floor C (see. 2 ). The rear floor stops 20 . 21 are also using the pneumatic cylinder 10 respectively. 11 actuated. How farther 1 it can be seen, are at the top of the side walls A, B upper side stops 28 . 29 formed, which form a stop for the upper regions of the rear vertical edge of the side walls A, B. The upper side stops 28 . 29 be through a third pneumatic cylinder 26 (on the first press frame 2 arranged) and a fourth pneumatic cylinder 28 (on the second press frame 3 arranged) actuated.
To the respective position of the lower side stops 12 . 13 and the upper side stops 28 . 29 To be able to determine are impression cylinders 14 . 15 respectively. 30 . 31 intended. Closer is at the bottom side stop 12 an impression cylinder 14 , at the bottom side stop 13 an impression cylinder 15 , at the upper side stop 28 a Ge impression cylinder 30 and at the upper side stop 29 an impression cylinder 31 arranged (cf. 1 ). The impression cylinder 14 . 15 . 30 . 31 form together with each one arranged on each impression cylinder sensor sensor means to determine a clamping of the side walls A, B. The sensors, not shown, on the impression cylinders 14 . 15 . 30 . 31 determine whether the impression cylinders have each taken their rear end position, as when operating the side stops 12 . 13 . 28 . 29 the impression cylinder also via the pneumatic cylinder 10 . 11 . 26 . 27 be operated.
To the side walls A, B between the vertical stops 8th . 9 and the lower side stops 12 . 13 or the upper side stops 28 . 29 to clamp, a predetermined relatively small pressure by the pneumatic cylinder 10 . 11 . 26 . 27 exercised. The pressure is chosen such that the side walls A, B can be securely clamped, but a risk of crushing a person working on the mounting device by the relatively small pressure is low.
The lower cabinet floor 10 gets on back ground pads 16 . 17 and front floor pads 18 . 19 . 38 . 39 hung up. The front floor pads are formed in two parts, with the parts 18 and 19 are lowerable. The lowered position is in 1 shown. The parts 18 . 19 can be lowered by approx. 25 mm, as pedestal feet can be fixed underneath the bottom of the cabinet. As in 1 shown are the front floor pads 18 . 19 . 38 . 39 formed like a sheet. The rear floor pads 16 . 17 are a bit smaller. As in further 3 shown, the lower cabinet floor C continues on two counter bearings 34 . 35 on. How out 3 it can be seen that the counter bearings 34 . 35 , thereby pivotally mounted about a pivot axis S1 and S2. The pivot axes S1, S2 are fixed to the base frame 1 anchored.
To an upper cabinet floor D (see. 2 ) is on the first press frame 2 a press frame 22 and on the second press frame 3 a press frame 23 arranged. The pressing frames 22 . 23 are in the direction Z vertically at the press frames 2 respectively. 3 traversable. As a result, the mounting device is able to mount corner cabinets of different heights. Further, by each of the pressing frames 22 . 23 a vertical pressing force for mounting the corner cabinet exerted. The drives of the press frame 22 . 23 are varied and can, for example, according to the drive of the press frame 2 . 3 to get voted. Like from the 1 to 3 it can be seen, are the press frame 22 . 23 while on rails 40 vertically movable.
How out 3 it can be seen are on the press frame 22 . 23 pressing elements 36 respectively. 37 arranged. The pressing elements are similar to the counter bearings 34 . 35 about a vertical axis S3 and S4 pivotally mounted (see. 3 ). It should also be noted that the pressing elements 36 . 37 to the press frame 22 . 23 Can be slidably arranged in the horizontal direction to be aligned with differently designed corner cabinets can. Here they are attached to the carriage plates, by the pneumatic cylinder 26 and 27 be moved. Like from the 2 and 3 it can be seen, are the pressing elements 36 . 37 while on an upper side of an upper cabinet floor D on. In this embodiment, the upper cabinet floor D is formed as a frame member having a relatively large center opening. It should be noted, however, that the upper cabinet floor D, like the lower cabinet floor C, also be designed as a panel element.
As holding devices for holding the upper cabinet floor D are two suction devices 24 and 25 intended. A suction device 24 is on the first press frame 22 arranged and the second suction device 25 is on the second press frame 23 arranged. The suction devices 24 . 25 can hold the upper cabinet floor D in position by sucking the top of the upper cabinet floor D. As with the pressing elements 36 . 37 could the aspirators 24 . 25 also be provided adjustable in the horizontal direction. In the illustrated embodiment, however, they are firmly mounted on the press frame.
For the upper cabinet floor D are upper rear floor stops 32 . 33 to the press frame 22 respectively. 23 intended. The upper rear floor stops 32 . 33 are doing as the lower cabinet floor C by the pneumatic cylinder 26 . 27 actuated. Thus, the third pneumatic cylinder operates 26 the upper rear floor stop 32 and the upper rear side stop 28 and the fourth pneumatic cylinder 27 operates the upper rear floor stop 33 and the upper rear side stop 29 , It should be noted that the upper sidewall stop 29 , the impression cylinder 31 , the upper rear floor stop 33 and the pressing element 37 attached to a carriage plate passing through the pneumatic cylinder 27 is moved to position. The same applies to the corresponding parts 28 . 30 . 32 and 36 on the other press frame.
It should be noted that the pneumatic cylinder 10 . 11 . 26 . 27 can also be replaced by hydraulic cylinders, rack drives or other motion actuators. Regarding the impression cylinder 14 . 15 respectively. 30 . 31 It should be noted that this in the assembly process of the corner cabinet to do so used, the rear lower floor stops 20 . 21 or the rear upper floor stops 32 . 33 away from the cabinet floors C, D, without damaging the cabinet floors, but the side walls A, B remain clamped anyway. This should be the cylinder 10 . 11 . 26 . 27 be switched back to the low pressure, otherwise their forces are too large.
In the 1 shown front floor pads 18 . 19 can be designed so that they can be moved by means of pneumatic cylinders in the vertical direction, for example. This can ensure that the height of the front floor pads 18 . 19 can be changed, since in particular at the bottom of the lower cabinet floors C base feet are already preassembled for the corner cabinet. In the same way, the rear floor pads can 16 . 17 and the rear floor stops 20 . 21 in the vertical direction, for example by means of pneumatic cylinders are moved. This can also be ensured that after installation of the corner cabinet all lower supports and stops can be moved vertically downwards, so that the mounted corner cabinet can be easily transported out of the work area W of the device without these components are disturbing. An alternative to the lowerable lower stop or bearing surfaces is to provide a lifting device which raises the mounted corner cabinet in the vertical direction, so that it can be easily removed from the mounting device.
becomes the function of the automatic corner cabinet installation device
or the assembly method according to the invention
In 1 a coordinate cross is shown, by means of which the direction of movement of the individual components of the automatic assembly device are designated. X denotes a movement in a linear direction, Y a movement in a linear direction offset by 90 ° thereto, and Z a movement perpendicular to the plane spanned by the directions X and Y.
As already explained above, first the side walls A and B on the support elements 4 . 5 , the support rails 6 . 7 and the vertical stops 8th . 9 created. Subsequently, the side walls are sucked by not shown vacuum suction, so they can not fall over. Next, as in 2 shown, first applied the lower cabinet floor C and then placed the upper cabinet floor D directly on the cabinet floor C. If the cabinet bottoms C, D are already superimposed, they can of course also be inserted simultaneously. After inserting the two cabinet bottoms C, D, the press frames move 22 and 23 , which are preferably driven by servomotors driven ball screws, at the same time in a parallel manner down to the cabinet bottom D with the suction devices 24 and 25 to suck and hold. In the present embodiment are as holding devices, the suction devices 24 and 25 provided, but it is also possible to hold the upper cabinet floor D, for example by means of mechanical gripper.
After the upper cabinet floor D on the suction devices 24 . 25 held, are the press frames 22 . 23 moved simultaneously in parallel to their intended position (ie their height in the Z direction). This height is variable and depends on the height of the corner cabinet to be mounted. It should be noted that the suction devices 24 and 25 can also be designed so that they by means of pneumatic cylinder 24a ( 5 ) are vorsteuerbar, while the servo motors, the press frame 22 and 23 go down. Thereby, the collection time for the suction of the cabinet floor D can be reduced, since the press frame 22 . 23 no longer have to be driven completely down, but the suction devices 24 . 25 have already been pulled down a bit. This is also necessary if the press frames can not be moved all the way down, because additional clamping elements 41 ( 3 ) must be provided for front trusses E and F.
By suction on the support elements 4 and 5 adjacent side walls A and B are by pressing the pneumatic cylinder 10 . 11 respectively. 26 . 27 clamped. This is where the pneumatic cylinders operate 10 . 11 the rear lower side stops 12 . 13 and the pneumatic cylinders 26 . 27 Press the rear upper side stops 28 . 29 , As a result, the side walls A, B are firmly clamped. For this clamping process bring the pneumatic cylinder 10 . 11 respectively. 26 . 27 only a relatively small force in order to minimize the risk of crushing persons working on the device. As the pneumatic cylinder 10 . 11 respectively. 26 . 27 also the lower floor stops 20 . 21 for the lower cabinet floor C and the upper floor stops 32 . 33 press for the upper cabinet floor D, the clamping process of the walls of the corner cabinet is carried out only when the upper cabinet floor D has reached its final position. If the four walls of the corner cabinet are securely clamped, by means of the sensor device, which from the counter-pressure cylinders 14 . 15 respectively. 30 . 31 and each arranged thereon, not shown sensors, a control sent a signal that the walls and floors of the corner cabinet are securely clamped. Upon receipt of this signal, the controller switches the pneumatic cylinders 10 . 11 and 26 . 27 to a high pressure, which was significantly higher than that used to clamp the walls and floors Pressure is. Due to the high applied pressure, the pneumatic cylinders take the forces of the servo axes on the press racks during the subsequent pressing of the walls or floors of the corner cabinet 2 . 3 on.
Thus, if all side walls or cabinet bottoms are at their end positions, the actual pressing process for mounting the corner cabinet takes place. Here are the two press frames 2 . 3 moved in the X or Y direction to perform the pressing operation. The pressing of the side walls A, B with the cabinet floors C, D takes place in a known manner by means of wooden dowels, which were introduced in advance, for example, in the cabinet floors and corresponding holes formed in the side walls A, B are pressed. As the pneumatic cylinder 10 . 11 and 26 . 27 have been switched to high pressure, acting on the side stops 12 . 13 , the ground stops 20 . 21 , the upper side stops 28 . 29 and the upper floor stops 32 . 33 each forces against the forces of the press frames 2 . 3 , Thus, the pneumatic cylinder 10 . 11 . 26 . 27 when pressing through the press frames 2 . 3 absorb applied high forces.
After the corner cabinet body is fully assembled, it may be removed from the machine as previously described by an ejector or by lowering the bottom stops and supports. The pneumatic cylinders 10 . 11 . 26 and 27 are switched to low pressure. Alternatively, for example, a carousel for kitchen cabinets or additional cabinet floors or other cabinet furnishings can be installed in the corner cabinet first. Also, the press frame 22 and 23 be driven upwards, so that the suction devices 24 and 25 not disturbing.
In 4 the forces acting on the corner cupboard during pressing are shown. Through the press frame 2 In this case, a pressing force F P1 is exerted in the X direction and through the press frame 3 a pressing force F P2 exerted in the Y direction.
At the same time are switched by the high pressure to the first pneumatic cylinder 10 over the side stop 12 and the ground stop 20 Forces F S1 (on the side stop 12 ) and F B1 (on the ground stop 20 ), which counter to the force F P2 of the second press frame 3 are directed. In an analogous way by the pneumatic cylinder 11 over the side stop 13 and the ground stop 21 Forces F S2 (side stop 13 ) and F B2 (ground stop 21 ) in the X direction against the force F P1 of the first press frame 2 exercised. So that the corner cabinet is not pushed out of the device, F S2 + F B2 > F B1 applies.
3 shows the installation of an alternative corner cabinet, which additionally trusses E, F, G, H has. The trusses are provided in the vertical direction Z between the lower cabinet floor C and the upper cabinet floor D for stabilizing the corner cabinet. The trusses E, F, G, H are levered in before pressing the side walls and the cabinet bottoms. For this purpose, the suction devices 24 and 25 with additional cylinders 24b ( 5 ), which can perform a very short stroke, for example, 5 mm. This is more accurate in 5 shown. F Z1 denotes the force through the cylinder 24a and F T the force by manually levering the crosshead. The additional cylinder 24b applies a force F Z2 which is opposite to the forces F Z1 and F T (cf. 5 ). By levering the trusses of the upper cabinet floor D is thus raised briefly and after the traverse has reached its final position, eliminates the Einhebelkraft F T , so that the upper cabinet floor D returns to its original position. Thus, one after the other the trusses E, F, G and H can be levered. The levering can, for example, automatically by means of a robot or similar. be executed. As in 5 indicated, located at the ends of the traverses wooden dowels, so that the lower wooden dowel of a traverse can be inserted into a hole in the bottom cabinet C and is introduced after levering in a hole which is formed on the upper cabinet floor D. The trusses can now no longer fold len, so that additional holding devices for the trusses need not be provided. After the trusses E, F, G, H have been introduced in such a way, in a first step, first the upper and lower cabinet floor C, D with the trusses E, F, G, H are pressed by the frame 22 . 23 be moved in the Z direction down. Subsequently, as in the previously described embodiments, the side walls A, B are pressed with the cabinet bottoms C, D. It should be noted here that the trusses can be introduced depending on the purpose of the corner cabinet in any number and position.
6 shows a further alternative embodiment of the present invention. Unlike the ones in the 1 to 5 shown embodiments are in this embodiment instead of the rear lower floor stops 20 and 21 several floor stops 20a . 20b . 20c and 21a . 21b . 21c immediately adjacent to each other. The rear bottom edge of the cabinet bottoms C and D can be at a variable distance K to the rear side edges of the side walls A and B. The reason for this is that, depending on the type of corner cabinet, another measure K is available. These different dimensions K thus determine the different rear bottom ren floor stops 20a . 20b . 20c respectively. 21a . 21b . 21c , Of course, the same applies to the rear upper floor stops 32 . 33 which are formed in a similar manner as the lower floor stops.
