Definitions
- the invention relates to a peripheral auxiliary device for the automatic loading and disposal of a punching-nibbling machine according to the preamble of claim 1.
- Punching-nibbling machines are used to punch out pre-fabricated parts of specified geometry from raw boards with a larger footprint.
- a punching-nibbling machine usually has a ruler with which the blanks can be moved in a certain area.
- the parts of the desired geometry can be punched out using a punching head, which receives the appropriate tools from the assigned cutting tool turret magazine.
- DE-A-27 21 440 describes an independently operating stacking device for stacking sheet metal sections, in which the stacking device forms a pivotable and displaceable roller conveyor.
- DE-A-10 51 737 in particular discloses a so-called rocker table, the posts of which form swivel bearings both with the standing surface and with the storage surface.
- the object of the invention is to create a peripheral auxiliary device using an industrial robot, with which the loading and disposal of a punching-nibbling machine can be further optimized.
- punching-nibbling machines which have been manually loaded or disposed of so far can also be retrofitted without mechanical changes to the machine.
- overall arrangement - that is essentially a freely programmable handling device and the peripheral auxiliary device according to the invention - a system is created with which the most varied of workpieces can be handled under program control.
- the special design of the gripping device on the one hand and the storage device on the other hand play an important role. Since both the large delivery boards and the possibly small finished parts are to be handled with the punching machine with the auxiliary device and the latter are only accessible through a narrow channel when the pliers ruler is advanced far in the machine, the gripping device is V-shaped and has one after the other Vacuum suction principle working adhesive device suction cups in different, possibly changeable distance, which can be activated by program. In preferred training, group activation of certain suction cups is possible. This proves to be advantageous in particular for the residual board grids, which can practically only be grasped at the clamping edge by means of the suction cups for removal.
- an intermediate storage device is also provided, the storage surface of which can be pivoted and displaced in one operation.
- Such a storage device known per se is referred to as the "rocker table" and makes it possible to layer the residual lattice structures that are sensitive to bending and interlocking in layers.
- FIG. 1 shows the frame of a punching-nibbling machine, which is numerically controlled in modern technology.
- the punching head of the machine to which a cutting tool turret magazine 12 is assigned, is designated in detail by 11.
- the punching-nibbling machine is assigned 1 different work tables for handling the raw blanks, finished parts and scrap skeletons.
- Under the punching head 11 there is a fixed table 15, which is followed at the rear by a crawler link table 16.
- a ruler 17 for guiding the boards during processing is arranged.
- the travel range of the ruler 17 is indicated by 18.
- a so-called "rocker table”, which serves as an intermediate storage facility, is identified by 20.
- a storage table 25 for finished parts is provided.
- An industrial robot 30 is assigned to the punching machine 1 described above. Such robots with a handling arm 35 are known from the prior art.
- a gripping device 40 is attached to the handling arm 35, with which raw boards, finished parts and scrap skeletons can be handled.
- the gripping device 40 is described in detail below.
- a raw board stack is indicated in FIG. 1, which is designated by 19.
- the gripping device 40 is constructed from a V-shaped frame. With 41 to 44 mechanical carriers are designated, which are arranged by appropriate connecting devices 45 to 48 in the intended geometry.
- the fastening unit for the robot arm 35 is designated by 49.
- the gripping device is geometrically designed such that the support arm 42 comes to rest on the edge of a circuit board, while the support arm 41 approximately represents the diagonal.
- the gripping device works with suction elements based on the vacuum suction principle, with which flat parts such as blanks, stamped parts and / or scrap skeletons can be handled.
- Suction cups 51 to 64 are therefore attached to both supports 41 and 42 at a predetermined distance, which can be connected to a pneumatic vacuum system and can be activated individually or in groups in the sense of suction on a surface.
- two suction cups 65 and 66 on the front are also attached via a cantilever 50 which can be moved mechanically or pneumatically.
- the boom arm can consist of a rod 501 which can be displaced in its longitudinal axis, a gear chain 502 and an associated helical spring 503.
- a pair of leaf springs can also be used to align the chain.
- the suction cups 51 to 66 are arranged at predetermined intervals on the frame. The distances can be changed manually or in a controlled manner. It is essential that the individual suction cups 57 to 66 can be activated separately or according to groups according to a control program, which is important in the context of the alternative handling of the raw boards, waste or finished parts and / or the residual skeleton. Different suction cup groups or areas must be activated for the various work steps. This is shown in detail in FIG 3 for four examples.
- the black suction cups are activated for lifting a blank 19. Usually not all of the edge or diagonal suction cups are required; the suction cups 65, 66 of the boom 50 are not activated.
- Part c shows the activation of suction cups for a larger finished part 191. Depending on the size of such a part, suction cups in the V-shaped tip area and also on the correspondingly extended arm 50 are activated.
- each suction cup can be activated individually according to the program.
- the suction cups 51 to 66 are advantageous in specific groups Problem adjusted activated. It has been shown that a sufficient combination possibility is given with six on / off switching signals. The choice of combinations depends not only on the size of the parts, but also on their geometry. For small parts with small ones or narrow contact surfaces for the suction cups, for example, it may be necessary to use specially developed suction cup structures.
- FIG. 4 schematically shows the function of the so-called "rocker table” 20 for storing the scrap skeletons.
- rocker table is attached to the base 210 with its storage surface 201 via four swivel joints 202 to 205 via mechanical levers: the function essentially consists in the fact that such a rocker table 20 with its storage surface 201 can be pivoted and moved in the same operation.
- This is indicated in the partial figures a, b and c. 220 identifies the storage area for the scrap skeleton to which a vertical stop surface 221 is assigned.
- the rocker table 20 With the residual grating 190 resting on the surface 201, the rocker table 20 can be tilted at an angle. When a certain helix angle of the surface 201 is reached, a residual screen 190 can slowly slip due to the overcoming of the static friction. However, it makes sense to give the movement sequence a certain dynamic.
- the table 20 is pivoted at a predetermined speed against a lower, possibly damped stop, so that the scrap skeleton 190 shoots obliquely forward against the stop 221.
- the scrap skeleton 190 slides down with the leading edge down to the level of an already existing stack 225.
- the scrap skeleton board 190 is not pulled along due to its inert mass and remains in contact with the stop edge 221 until the support from the surface 201 is lost on the other side edge.
- the board folds onto the existing stack.
- the rocker table 20 is folded down for the punching process. This is followed by the numerically controlled punch-nibble program sequence up to the free separation of a first finished part.
- the punching machine 1 then goes into the holding lock. Subsequently, the robot arm 35 is pivoted in and the gripping device 40 with the cantilever arm 50 moves forward into the channel between the pliers ruler 17 and the cladding of the cutting tool magazine 11. After this, a finished part can be removed, with one or more suction cups being activated as required on the gripper tip . Precast parts are deposited, for example, on the deposit table 25. Waste pieces can also be removed and dropped in a waste container.
- the pliers ruler 17 After all finished parts have been punched out of a blank, the pliers ruler 17 returns to the standard position and the punching-nibbling machine 1 goes into the holding position. Then the rocker table 20 is folded up.
- rocker table 20 is folded over, so that, as described in detail with reference to FIG. 4, the remaining grid 190 slides off at an angle and comes to lie one above the other in layers.
- peripheral auxiliary device enables optimal handling of the blanks, finished parts and scrap skeletons for a punch-nibble machine with an existing industrial robot.
- the suction cups of the gripping device can be activated according to the program.
- the exact positioning can also be changed and carried out according to the program.
- the suction cup holders would have to be arranged displaceably on the frame, for example by pneumatic cylinders.
- One design option would be to limit the displacement of the suction cup holders by means of a grid of programmable stops. In practice, it may be sufficient in many cases if the extension arm 50 is equipped accordingly.
