On the press, it is usually done vertically Towards the placement of the board. The feeder or general Transfer device then returns by reversing the described movements back to the stack of boards.
  • DE 34 01 703 A1 describes a feed device for gradual transport known especially in presses that has two gripper rails, which with one Feed carriage fixedly and transversely movable in the feed direction are coupled.
  • Gripper rails can be moved together in the feed direction. crosswise to the direction of feed are the gripper rails by means of a Cross drive driven in opposite directions.
  • a suitable one Guiding a timing belt for example opposite transverse movement by a single drive will be realized.
  • this drive must with the Feed slides can be moved, so that the drive for the feed carriage is comparatively large must become.
  • those cables that are connected to the Run transverse drive constantly moving what during operation the integrity of the cables is endangered or expensive Protective measures required.
  • a transfer device is known from DE 25 34 820 A1, at which a sled over by a fixed motor an endless belt firmly attached to the sled is proceeded. Raising and lowering a ram in the Sledge is carried out by an also fixed Lift drive, which has another belt over the slide and in particular is guided over the tappet.
  • the invention has for its object a simple designed and easy to operate transfer device create, with fixed and particularly small dimensionable motors with two movements different directions independently can be realized.
  • the transfer device a guide on which a carriage can be moved.
  • the guide on which the carriage can be moved is designed to be fixed.
  • the leadership regarding a fixed Frame or frame is movable to by means of the movable Lead a movement in a third direction, in addition to the two directions by means of the invention Transfer device can be realized to accomplish.
  • On the slide a plunger is movable in a direction that differs from the direction of movement of the slide.
  • the term "plunger" indicates that the plunger is with respect to the carriage usually in the vertical direction will move while the sled is usually in moved horizontally.
  • the facility could be like this be designed so that the slide is moved horizontally, and the plunger to the direction of travel of the slide in Essentially vertical, but also horizontal.
  • the transfer device such that two independent, horizontal movements realized the device unfolds its advantages.
  • the so-called carriage could be vertically movable, and the ram horizontally in any direction.
  • the transfer device enables two Movements through a particularly simple and little fault-prone facility can be realized in that two motors that are at least fixed with respect to the slide are provided.
  • the two motors drive a first and a second drive wheel section together with a third drive wheel section rotatable together, however provided non-rotatably with respect to each other on the carriage are.
  • the drive wheel sections are preferably fixed to one common shaft attached or together on an axis rotatably provided.
  • the three Drive wheel sections not movable with respect to each other.
  • first and second drive wheel section are traction devices, in particular a belt or a Chain, engaged on opposite sides.
  • first or second drive wheel section is on it Top driven, and the other drive wheel section is driven on its lower side.
  • the two traction devices on the opposite sides with the respective drive wheel section are engaged and by appropriate measures are kept in engagement.
  • the traction means at least in sections around the respective drive wheel section are looped. For example, by suitable Deflection pulleys before and after the respective drive wheel Traction means, for example a toothed belt, on about half Circumference of a drive wheel section are guided around this.
  • the other traction device is accordingly on the opposite side around part of the drive wheel section looped.
  • that flexible means such.
  • B. timing belt or Chains are particularly suitable. Basically, however, it is also conceivable by a suitable drive Rack to move that to a suitable side with the respective drive wheel section is engaged.
  • each The traction means over the first or second drive wheel must first motor just to be driven in the other direction than the second motor to operate by means of the engagement between the respective traction means and the drive wheel a rotation of To realize shaft in the sled.
  • a single engine with two To provide drive wheels which by a suitable, switchable gearbox on the one hand in the same direction, and on the other hand drivable in opposite directions are.
  • the Drive movements in the invention Transfer device realized by a single motor become.
  • Such an arrangement also corresponds to that basic idea according to the invention, even if subsequently by two separate engines.
  • the joint rotation of the first and second described above Drive wheel section also the third drive wheel section driven, which is drivingly connected to the plunger, so that by rotating the third drive wheel of the plunger can be moved with respect to the carriage.
  • the drive wheel will preferably be designed as a gear, that with a rack or a timing belt, the / the firm are attached in or on the plunger, is engaged.
  • the movement of the Tappet can be reached with respect to the carriage.
  • the two drive motors not in the opposite direction driven, but in such a way that the two in opposite direction around the two drive wheels guided traction means in the same direction on the two Pull the drive wheels.
  • the traction means as mentioned, on opposite sides are guided over the drive wheels, pulls the one traction device “up” on the associated drive wheel, while the other traction device on the Drive wheel “down” pulls in the same direction. hereby however, no rotation of the common shaft is generated, rather, the sled is made by the interaction of the two Drive motors move.
  • the latter aspect is a particular advantage of the transfer device according to the invention in addition to the fact that the two motors are designed to be stationary can.
  • the two motors work with the Realization of all movements together. As last described, pull both motors over the respective Traction means on the respective drive wheel and thus overall on the sled to move it together. Further becomes the rotation of the third, as described above Drive wheel, and thus the movements of the ram with respect of the carriage through the interaction of the two motors reached. This makes the motors particularly small be interpreted because neither of the two motors "alone" for the movement of the slide or the plunger is provided.
  • both motors can at least with respect of the slide are fixed so that none the two motors must be designed for the other Motor together with the element actually to be moved, that is to move the sledge.
  • the Transfer device according to the invention no cables to a moving motor would have to be guided. This is the integrity of the cables is ensured and there is no need for them elaborate protective measures for the constant movement and in particular cables subjected to bending.
  • the drive wheel sections are preferably provided as separate drive wheels, leading to that
  • the advantage is that the respective traction means on each other delimited places with the respective drive wheel in Are involved and do not conflict with each other can.
  • the two Drive motors each have a device for path control assigned to the engine.
  • the experts are familiar with that under a path control of the respective motor it is understood that by means of an exact assignment in a very fine grid is set, to which Time the device moved by the motor on what place is located. With this technique they can Movements of the two motors can be controlled such that their output deviates from one another to such a small extent that there are no unwanted movements to fear.
  • both motors are used at the same time exactly coordinated movements on the movable Have to pull the sled to move it. If the Movement of one of the two motors from that of the other Motors deviates, this leads to a, as explained above at least slight rotation of the axis on which it is located all drive wheels are located. Such a rotation would cause at least a slight movement of the ram regarding the sled trigger what is not wanted and is particularly dangerous.
  • Path control and the precise result achieved Movement control of the two drive motors can do this prevented and reliable and trouble-free operation guaranteed the transfer device according to the invention become.
  • the traction has the Using toothed belts as particularly advantageous exposed. It should be noted that basically also Chains or any comparable devices possible are. However, timing belts can be used for the invention Be designed in such a way that their elongation increases Keeps stress within reasonable limits.
  • the Traction means in particular the timing belt, over comparatively long distances, namely via the travel path of the sled and back to the fixed motors be performed.
  • the traction means To advantageously prevent that the traction devices tend to move between deflection points the comparatively long, free pieces to swing, is preferred according to the invention for the traction means To provide guidance. This tour extends parallel to the direction of movement of the slide to a certain extent laterally of the respective traction device and leads at least one specific location of the traction device.
