Definitions

  • the present invention relates to a blasting installation with a blasting cubicle with a closable and releasable opening through which a workpiece to be blasted can be introduced into the blasting cubicle and removed from the blasting cubicle, and with at least one blasting device, such as a blasting wheel, by means of which the workpiece located in the blasting cubicle can be irradiated with a blasting medium.
  • Blasting systems of the aforementioned type are known from the relevant practice.
  • a plurality of blasting devices with different blasting directions are used and / or the blasting work piece is moved in the blasting cabinet during blasting relative to the blasting device and to the blasting machine moved by this generated Strahlffenstrahl.
  • the shows DE 27 47 107 A1 a blasting system with a blast cabin with a closable by a door and releasable opening through which a workpiece to be radiated in the blasting cabin can be introduced and removed from the blasting cabin.
  • the blasting system has at least one blasting device, by means of which the workpiece located in the blasting cabinet can be irradiated with a blasting medium.
  • the DE 101 03 630 A1 shows a processing plant with a arranged in a processing cell processing robot with which a workpiece can be edited.
  • the processing cell is bounded by walls, of which at least one wall has an opening with at least one rotatable about an axis of rotation Has workpiece receiving element.
  • two opposing openings are provided, wherein a first workpiece receiving element can be equipped on the externally accessible side of the machining cell with a workpiece to be machined, while at the same time a mounted on the opposite inner side of the machining cell on the workpiece receiving element workpiece can be edited with the processing robot.
  • the processing cell must be accessible from several sides and the workpieces have to be removed both at different points of the processing cell, which leads to a large space requirement of the system and to a cumbersome supply and removal of the workpieces.
  • the US Pat. No. 3,309,818 discloses a blasting system with a blasting cubicle with a closable and releasable opening, through which a workpiece to be blasted can be introduced into the blasting cubicle and removed from the blasting cubicle.
  • the blasting system has at least one blasting device, by means of which the workpiece located in the blasting cabinet can be irradiated with a blasting medium.
  • this document discloses the arrangement of a workpiece holder at the in the closed position to the interior of the blast cabin facing side of the opening of the blast cabinet associated door.
  • a disadvantage is considered that during the attachment of a workpiece to be blasted on the workpiece holder and during removal of the blasted workpiece from the workpiece holder beam operation is not possible, whereby here the effective service life of the blasting machine is limited.
  • the blasting installation according to the invention thus has two doors at the opening of its blasting cabin, of which one or the other can be brought into the closed position and open position, as desired.
  • Each of the two doors has a workpiece holder, wherein in each case the workpiece holder of the door in the closed position holds and carries a workpiece within the blasting cabinet during a blasting process.
  • the other door is in the open position, so that now the workpiece holder is accessible from the outside. With this accessible workpiece holder, therefore, another workpiece to be blasted can be brought into engagement even while the blasting process is still running, or a workpiece which has previously been blasted can be removed from the workpiece holder.
  • the shotgun need not be stopped; Rather, these processes proceed simultaneously with a blasting process.
  • the blasting system according to the invention achieves a particularly high efficiency, because their blasting device or blasting devices only have to be shut down for very short times, namely only when the door is transferred from its closed position to the open position and the other door from its open position to the closed position which only takes a very short time.
  • the opening preferably rectangular, is designed with two vertical edges and that each of the two vertical edges each one of the doors is hinged.
  • the weight of the doors has so advantageous no force in the opening or closing direction, which allows a smooth pivoting of the doors.
  • each door is expedient by at least 90 °, preferably by up to 180 °, pivotable.
  • the minimum amount of pivotability depends in particular on the dimensions of the respective workpiece to be machined, since this usually in the open position of a door is the most projecting towards the other door element.
  • the swing angle of the doors must be at least so large that it certainly can not come to collisions.
  • each door is preferably associated with a power drive for its pivoting.
  • a power drive for its pivoting.
  • the pivoting of the doors can advantageously be remote-controlled.
  • Each power drive can be performed, for example, hydraulically or pneumatically or formed by an electric motor.
  • each door is assigned at least one locking device with which the door can be releasably locked in the closed position and / or in the open position. An undesired automatic adjustment of the doors during operation is thus reliably prevented.
  • the power drives for pivoting the doors in their closed position and / or open position can be relieved.
  • each workpiece holder has two grippers which are adjustable relative to one another and hold one another to hold the workpiece. The workpiece can thus be detected by the grippers with a small amount of time and kept sufficiently safe for a blasting process.
  • each workpiece holder is expediently assigned at least one power drive for adjusting its grippers.
  • this power drive can be performed, for example, hydraulic or pneumatic or formed by an electric motor or electromagnet.
  • each workpiece holder for clamping of the grippers against each other at least one tension spring arrangement can be assigned.
  • the invention proposes that the grippers of each workpiece holder together with a workpiece held thereon can be rotated about a common axis of rotation. In this way, the workpiece can be rotated during a blasting process about the common axis of rotation of the gripper to achieve a uniformly uniform irradiation of the workpiece.
  • the common axis of rotation of the gripper runs parallel to a surface plane of the associated door.
  • each workpiece holder is expediently assigned in each case at least one geared or servomotor as a rotary drive for its grippers.
  • each workpiece holder is rotatable about an axis of rotation perpendicular or oblique to a surface plane of the associated door. This allows a rotational movement of the workpiece during a blasting process about a second axis of rotation, which has a different direction than the aforementioned first axis of rotation. This leads to a particularly uniform all-round irradiation of the workpiece, even if only one jet device is provided in the blast cabin. The uniformity of the radiation becomes even better if two or even more blasting devices are arranged in the blasting cabin.
  • each door is expediently assigned at least one geared or servomotor as a rotary drive for the associated workpiece holder.
  • each gripper has a plurality, preferably three, adapted in their design and arrangement to the respective workpiece to be blasted and / or adjustable to adapt to the respective workpiece to be blasted finger.
  • the fingers of the grippers form only punctiform small contact points to the workpiece, so that only minimal areas of the workpiece are not reached by the blasting medium. With only three fingers per gripper, a sufficiently positionally secure mounting of the workpiece in the workpiece holder is already achieved.
  • the fingers of each gripper preferably by means of a quick-change device, interchangeably connected to the respective remaining gripper.
  • each gripper may be multi-membered and, preferably without tools, adjustable and lockable in their length and / or orientation.
  • the fingers of each gripper may be multi-membered and, preferably without tools, adjustable and lockable in their length and / or orientation.
  • the blasting machine has at least one workpiece handling robot, with each of which a workpiece before a blasting process one of the workpiece holder can be fed and after a blasting process of the respective workpiece holder is removable.
  • the workpieces to be radiated are expediently fed via a conveyor device, from which the workpiece handling robot can take over a workpiece and feed it to the workpiece holder.
  • the blasting system is expedient downstream of a laxative conveyor, to which the workpiece handling robot can each pass a blasted, removed from the workpiece holder workpiece.
  • the blasting machine In order to enable a reliable and largely automatic operation of the blasting machine, it preferably has an electronic control unit for controlling and monitoring active elements of the blasting machine, in particular the doors, the blasting device (s), the power drives, the locking devices, the workpiece holder, the gripper, the adjustable finger, the rotary actuators and / or the workpiece handling robot on.
  • an electronic control unit for controlling and monitoring active elements of the blasting machine, in particular the doors, the blasting device (s), the power drives, the locking devices, the workpiece holder, the gripper, the adjustable finger, the rotary actuators and / or the workpiece handling robot on.
  • FIG. 1 The drawing shows a blasting machine 1, with a blasting cubicle 10, which has an opening 11 on its side facing the observer.
  • the opening is made rectangular with two vertical edges, wherein at each of the two vertical edges of a door 12.1 and 12.2 is pivotally articulated.
  • both doors are 12.1 and 12.2 in its open position, so that now the opening 11 of the blast cabinet 10 is free.
  • a respective locking device 16.1, 16.2 the two doors 12.1, 12.2 are releasably locked in their open position.
  • one of the two doors 12.1, 12.2 is selectively pivotable from the open position to the closed position.
  • the doors 12.1 and 12.2 are each an associated power drive 15.1, 15.2, which are each arranged above the two vertical edges of the opening 11 of the blast cabin 10.
  • blasting devices 13 in the form of blast wheels or centrifugal turbines are connected at the top left and bottom right, with each of which a fan-like blasting agent jet 13 'can be generated.
  • the jet devices 13 can only be put into operation when the opening 11 of the blasting cubicle 10 is closed by one of the two doors 12.1, 12.2.
  • the lower part of the blasting cubicle 10 forms a blasting funnel 14, in which the blasting agent collects and from where the blasting agent can be fed to a reprocessing device, which in FIG. 1 is shown schematically above the blast booth 10 and which is known per se.
  • each workpiece holder 3 has two grippers 31.1 and 31.2, which are each equipped with three fingers 32.
  • the fingers 32 of the upper gripper 31.1 point down and the fingers 32 of the lower gripper 31.2 point upward. Between the fingers 32, the workpiece 2 is clamped. It is also possible to attach two or even more workpiece holders 3 to the doors 12.1, 12.2, which is for example for processing from in relation to the size of the blast cabinet 10 relatively small workpieces 2 may be appropriate.
  • the workpiece 2 is shown purely schematically in the drawing figures as a cube, which indicates the largest possible dimensions of the workpiece 2; In reality, the workpiece 2 usually has other shapes, but these can be virtually arbitrary.
  • the upper gripper 31.1 relative to the lower gripper 31.2 displaceable in the vertical direction, as indicated by the double arrow on the workpiece holder 3.
  • the fingers 32 are rotatably connected to the respectively associated gripper 31.1, 31.2 and rotatable with a rotary drive 35 in rotation, so that with this the clamped workpiece 2 to the in FIG. 1 vertical axis 33 is rotatable.
  • the fingers 32 are exchangeably connected to the respective associated gripper 31.1, 31.2 by means of a quick-change device in order to be able to use different adapted fingers or finger arrangements 32, depending on the shape of the respective workpiece 2 to be machined.
  • each workpiece holder 3 is rotatably mounted in total on the associated door 12.1, 12.2 about a horizontal axis 30 and by means of a respective provided on the door 12.1, 12.2 rotary drive 34 can be set in rotation.
  • the workpiece 2 can thus be set in the workpiece holder 3 simultaneously by two mutually perpendicular axes of rotation 30 and 33 in rotation. This superimposed rotational movement ensures that the workpiece 2, which is located in the interior of the blasting cubicle 11 when the door 12.1 or 12.2 is closed, is uniformly hit and processed by the blasting abrasive jets 13 'on all sides.
  • the two axes of rotation 30 and 33 do not have to be perpendicular to each other; an oblique, not rectangular course relative to each other is possible.

  • the removal and insertion of the workpieces 2 is preferably carried out by means of one or two workpiece handling robots, which are not shown here. Alternatively, the removal and insertion of the workpieces 2 can also be done manually.
  • the blasting devices 13 are switched off and the door 12.2 is transferred by the power drive 15.2 from the closed position to the open position and locked by means of the associated locking device 16.2.
  • the first door 12.1 is pivoted with the clamped in the workpiece holder 3 further workpiece 2 by releasing the locking device 16.1 by the associated power drive 15.1 from the open position to the closed position, after which a new blasting process begins.
  • This state of the blasting machine 1 is in the FIG. 3 shown, in which now the first door 12.1 is in its closed position and the second door 12.2 is in the open position. Now, the blasted workpiece 2 can be removed from the workpiece holder 3 of the second door 12.2, and then a new workpiece 2 to be blasted can be inserted into this workpiece holder 3.
