Definitions

  • Width-adjustable conveyor for transporting workpieces
  • the invention relates to a width-adjustable conveying device for transporting workpieces, in particular substrates in a placement device on at least one transport path with at least two parallel rail-like conveying units, the workpiece resting on both conveying units, at least one of which transversely to the conveying device by means of a revolving traction means is displaceable, which can be coupled to the displaceable conveyor unit at least temporarily.
  • Such a conveyor is known for example from EP 0854 670 Bl.
  • a conveyor device for printed circuit boards is described and shown therein, in which the printed circuit board rests with both side edges on two narrow transport belts which are guided in a narrow rail-like conveyor unit.
  • one of the two conveyor units can be displaced transversely to the transport direction of the printed circuit boards by means of a circumferential belt (FIG. 9, FIG. 12).
  • a driver of the displaceable conveyor unit is firmly connected to the belt.
  • the belt can be driven in opposite directions by means of a drive motor and thereby increase or decrease the distance between the fixed and the movable conveyor unit.
  • the invention has for its object to provide a device in which more than one of the conveyor units can be adjusted transversely to the conveying direction.
  • the fixing rail makes it possible to fix directly to a stationary part of the conveyor. Due to the switchable coupling to the traction means or to the fixing rail, both conveyor units can alternately be coupled and adjusted with the traction means or the fixing rail. This makes it possible not only to change the distance between the conveyor units, but also their central position.
  • the substrates can be arranged exactly in the middle of the adjustment path in order to equip them from both sides of the transport path under approximately the same conditions.
  • the development according to claim 2 ensures that the coupling to the fixing rail or to the traction means can be carried out by means of a single coupling element and a single clamping drive.
  • the conveyor device according to claim 3 has the particular advantage that the conveyor unit is securely held on the fixing rail when the clamping drive is deactivated, so that the respective settings are retained even when the conveyor device is completely shut down. Since the clamping drive only has to be activated for adjustment, the energy consumption remains low.
  • the developments according to claims 4 and 5 enable a very simple structural design of the clamping device.
  • the clamping drive can, for. B. have a flat pneumatic cylinder of large cross section. The required working stroke remains small.
  • the clamping drive according to claim 6 has the advantage that the actuating force remains low in accordance with the wedge angle of the movable part.
  • the toothed belt according to claim 7 transmits the movement of the drive motor to the search means without play.
  • the conveyor device according to claims 9 and 10 require only one adjustment drive for each of the displaceable conveyor units and are correspondingly inexpensive to manufacture.
  • the clamping device is fixed directly on the transverse guide without a clamping rail.
  • Figure 1 shows an end view of a conveyor for
  • FIG. 2 shows a plan view of the conveyor device according to FIG.
  • FIG. 3 shows a side view of the conveyor device according to FIG. 2 with a clamping device
  • FIG. 4 shows a partial view of the conveyor device according to FIG. 1
  • FIG. 5 shows an end view of the conveyor device according to FIG. 1 with two mutually parallel conveyor lines
  • FIG. 6 shows the conveying device according to FIG. 5 with only one conveying section
  • FIG. 7 shows an enlarged view of the clamping device according to FIG. 3 in an idle state
  • FIG. 8 the clamping device according to FIG. 7 in an actuation stage
  • Figure 9 shows a detail from a perspective view of another conveyor according to the invention.
  • FIG. 10 shows a further clamping device similar to FIG. 7
  • a conveyor device 1 consists of a chassis 2, rod-like transverse guides 3, fixing rails 4, a transverse drive 5, a longitudinal drive 6, and two rail-like conveyor units 7, which are parallel to one another and form a transport path, on which toothed belts 9 are guided all round.
  • a substrate 10 designed as an electrical printed circuit board lies with its side edges on the toothed belt 9. These are powered by an electric motor
  • the transverse guides 3 and the fixing rails 4 extend perpendicular to the transport direction x in the transverse direction y, as do two rotating traction means 12 designed as toothed belts, which can be driven forwards and backwards by the transverse drive 5.
  • the conveyor device 1 is provided for installation in a placement device with which the substrate 10 can be equipped with electrical components. Depending on the customer's specifications, the transport route should be right-justified or left-justified according to the conveyor units shown in dash-dotted lines, which is possible here with simple control commands without the need for retrofitting.
  • One of the traction means 12 and one of the fixing rails 4 are arranged adjacent to one another.
  • a clamping device 8 with a bow-like clamping piece 13 and a clamping drive 14 is fastened to the conveyor unit 7.
  • the bow-shaped, U-shaped clamping piece 13 engages around the fixing rail 4 and the band-shaped traction means 12 with its side legs which can be deflected resiliently against one another, between the inner ends of which the fixing rail 4 is clamped near the base of the clamping piece.
  • the preload is so great that the conveyor unit 7 is held securely in the respective position.
  • the traction means 12 is arranged between the two free ends of the clamping piece 13 and, at the level of the traction means 12, has a clamping drive 14 in the form of a flat compressed air cylinder, the pressure plate of which can be pressed under pressure against the traction means 12, which is opposed to it Side rests on the other leg of the clamping piece 13.
  • a clamping drive 14 By actuating the clamping drive 14, the traction means is clamped between the two leg ends. These are spread apart so far that the clamping to the fixing rail 4 is released.
  • both the traction means 12 and the fixing rail 4 are temporarily coupled to the clamping piece 13 in a temporal overlap, so that no slippage can occur during this handling process.
  • a control system ensures that the traction means 12 remains in a fixed position during this switching process.
  • the traction means 12 are arranged so that their drive wheels
  • the conveying units 16 is drivable.
  • the conveying units can thus be moved alternately or simultaneously in the transverse direction y by a predetermined distance and set to a new position.
  • a placement head is provided with a camera for recognizing positioning marks on the substrate.
  • the conveyor units 7 can also have such positioning marks on their upper side, the exact position of which can be detected by this camera. If there are any deviations in the position of a conveyor unit 7, these can be corrected by a further adjustment movement. It goes without saying that one of the positioning marks must be attached in the vicinity of each traction means in order to also be able to determine deviations in the alignment of the conveyor unit 7. This deviation can be corrected in that only one of the clamping pieces 13 is coupled to the associated traction means 12 in order to bring about a corresponding compensation stroke.
  • the position can also be determined in the manner indicated in FIG. 4 with the aid of e.g. bring about optical sensors 17 and markings 18 on the conveying units 7 and the traction means 12, a stationary sensor 17a defining a reference position from which the marking 18 can be moved to one of the sensors 17.
  • the distance covered which is a measure of the position of the respective conveying unit, is determined on the basis of the angle of rotation covered by the setting mode 16.
  • FIG. 5 shows the conveyor device 1 according to FIG. 1 with an additional conveyor section, which is formed by two further conveyor units 7. This is actuated by means of its own longitudinal drive, not shown, in order to be able to convey the substrates 10 in the transport direction x on it. Since each of the conveyor units can be moved and fixed individually, it is possible to position all of the conveyor units economically with a single actuator.
  • the conveying device 1 according to FIG. 5 has only one conveying path which uses almost the entire width.
  • the two conveyor units that are not required are fully constantly shifted to one side, so that the available remaining width enables the transport of approximately double-wide substrates 10a. This means that the conveyor can be used for both single and double-line operation without any retrofitting.
  • Figure 7 shows the clamping piece 13 of Figure 3 in an enlarged view in a rest position, in which the fixing rail 4 between the inner clamping surfaces of the two legs of the clamping piece 13 is clamped so tightly by the internal stress within the clamping piece 13 that the conveyor unit 7 in the respective Position is held securely.
  • the toothed belt of the traction means 12 is located between the free ends of the clamping piece 13 under the clamping drive 14 designed as a bellows cylinder. In the vented state, its pressure plate 19 is located force-free above the traction means 12 so that it can be pulled through without the conveying unit 7 to adjust.
  • the bellows cylinder is pressurized with compressed air, as a result of which the traction means 12 is clamped between the other leg of the clamping piece 13 and a coupling surface of the pressure plate 19 facing the traction means 12.
  • the compressive force is so great that the two legs spread apart slightly, as a result of which the frictional engagement with the fixing rail 4 is eliminated.
  • the associated conveyor unit can then be displaced in the transverse direction y by moving the traction means 12.
  • FIG. 9 shows another clamping device 8a, in which the band-shaped traction means 12 is arranged between a fixed support projection 20 and a movable pressure piece 21, in which the clamping drive 14 according to FIG. 8, not shown, is accommodated.
  • the traction means 12 is clamped between the pressure plate 19 and the supporting projection and the pressure piece 21 is lifted off the traction means 12.
  • a modified U-shaped clamping piece 13a stands with his Longitudinal axis perpendicular to the traction means 12.
  • its legs 22 At its ends, its legs 22 have rollers 23, between which the pressure piece projects with a wedge-shaped projection 21.
  • the fixing rail 4 is frictionally clamped between the two legs of the clamping piece 13 under spring preload.
  • the wedge-shaped projection is pressed between the two rollers 22 in a force-intensifying manner, so that the two legs 22 are pressed apart and release the fixing rail.
  • FIG. 10 shows another clamping device 8b, in which another clamping piece 13b surrounds the transverse guide 3, which is designed as a round rod, in a clamp-like manner and grips tightly in a frictionally locking manner when the clamping drive 14 is not actuated.
  • the transverse guide 3 also serves as a fixing rail, which is therefore not required.
