Definitions

  • the present invention relates to a workpiece feed device for a grinding machine, a grinding machine equipped accordingly, and a method for feeding workpieces for a grinding machine.
  • Grinding machines for example for face grinding, are well known in the prior art.
  • DE 40 27 633 A1 a grinding machine with an upper and a lower grinding ring and with an intermediate transport disk.
  • the latter has receptacles for workpieces that fall into the receptacles on the input side in a stacking magazine.
  • the workpiece feed device for a grinding machine, by means of which significantly more workpieces are fed into the grinding machine per unit time can.
  • the workpiece feed device should also be able to be integrated particularly well into existing concepts for workpiece feed and in this respect also enable the possibility of retrofitting existing workpiece feed devices.
  • the improved workpiece feed device is intended to provide a grinding machine with an increased throughput of workpieces and, in this respect, corresponding production or machining processes to be designed to be more efficient and less time-consuming.
  • a workpiece feed device for a grinding machine has at least one machining area. At least one rotatably driven or rotatably drivable grinding tool is typically located in the machining area.
  • the workpiece feed device has a movably mounted workpiece carrier with a number of workpiece holders for one workpiece each.
  • the workpiece holders are spaced apart from one another on the workpiece carrier in relation to a direction of movement of the workpiece carrier.
  • the workpieces that are received or held on it can be transported from a workpiece receiving area into the processing area and processed in the processing area by means of the grinding tool before the processed workpieces are removed from the processing area again by means of the workpiece carrier can be brought out and fed to a workpiece output.
  • the workpiece feed device has a workpiece feeder provided or arranged at a first position. This is designed for equipping workpiece holders guided past the first position with one workpiece each.
  • a second workpiece feeder is provided or arranged at a second position. This is used to equip workpiece holders that are guided past the second position, each with one workpiece.
  • the second position, at which the second workpiece feeder is arranged or provided, is spaced apart from the first position in the direction of movement of the workpiece carrier. Consequently, at least two, optionally also several workpiece feeders can be provided along the direction of movement of the workpiece carrier, by means of which a workpiece can be inserted or introduced into a workpiece holder of the workpiece carrier provided for this purpose.
  • two workpieces can be arranged or fastened simultaneously or staggered in time, or also overlapping in time, in the workpiece holders of the workpiece carrier provided for this purpose. In this way, loading the workpiece carrier with the workpieces can be accelerated. In this way, the number of workpieces to be machined per unit of time can be significantly increased while maintaining the machining parameters, such as the speed of movement of the workpiece carrier and/or the speed of movement of the grinding tool(s).
  • first and a second workpiece feeder By using at least a first and a second workpiece feeder, significantly more workpieces per unit of time can be placed or arranged in the receptacles of the workpiece carrier provided for this purpose. The capacity of the workpiece feeder can thus be significantly increased.
  • first workpiece feeder is arranged in a stationary manner at the first position and that the second workpiece feeder is arranged and/or fixed in a stationary manner at the second position.
  • the workpiece carrier is subject to continuous or indexing movement relative to the workpiece feeders.
  • the workpiece holders to be loaded are guided past the respective workpiece feeders or at least temporarily positioned for this purpose in such a way that a respective loading or an arrangement of individual workpieces is in the designated areas Workpiece recordings can be carried out simultaneously, at different times or with a time overlap.
  • the total holding capacity of the workpieces to be positioned, fixed or held on the workpiece carrier can also be increased. This also allows the throughput of the workpiece feed device to be increased and the efficiency of the grinding machine or of the entire welding process to be increased.
  • the workpiece feed device has a further, namely a third workpiece feeder, which is provided or arranged at a third position and which is provided or designed for equipping workpiece holders guided past the third position with one workpiece each.
  • the third position is spaced apart from the first position and from the second position in the direction of movement of the workpiece carrier.
  • a total of more than 100, more than 200 or even more than 300 workpieces per minute can be arranged or placed in the workpiece holders of the workpiece carrier.
  • the fact that the at least first workpiece feeder and the at least second workpiece feeder are spaced apart from one another along the direction of movement of the workpiece carrier means that all workpiece holders provided on the workpiece carrier can be sequentially and one after the other at the first position and at the second position, possibly also at the third position, which are each provided with workpiece feeders, are passed when the workpiece carrier is moved as intended.
  • the spatial area in which the workpiece carrier is loaded along its direction of movement can be enlarged in this way, so that a corresponding number of workpiece feeders can also be used on the first, the second and possibly also at the third position provided for this purpose can be arranged and installed without any problems.
  • the cycle times at which the workpiece feeders are to be activated can be reduced in accordance with the total number of workpiece feeders present. If, for example, two workpiece feeders are provided instead of a single one, the cycle times of the individual workpiece feeders can also be doubled and thus lengthened, which reduces the mechanical demands on the individual workpiece feeders. This enables the use of particularly robust, durable and inexpensive workpiece feeders to provide the individual workpiece holders of the workpiece carrier with workpieces.
  • a distance between the first position, at which the first workpiece feeder is located, and the second position, at which the second workpiece feeder is located is greater, viewed in the direction of movement, than a distance between workpiece holders of the workpiece carrier provided adjacent in the direction of movement.
  • the workpiece carrier has a multiplicity of workpiece holders arranged comparatively closely next to one another. Due to the offset arrangement of individual workpiece feeders in the direction of movement, it is possible, for example, for the first workpiece feeder to load only every second workpiece holder with workpieces and for the second workpiece feeder to load the remaining workpiece holders of the workpiece carrier with workpieces. If at least three or more workpiece feeders are provided, a further reduced equipping of the individual receptacles per workpiece carrier can be provided for each individual workpiece feeder.
  • the first workpiece feeder can load only every third workpiece receptacle of the workpiece carrier.
  • the second and the third workpiece feeder can then be designed to provide the remaining two thirds of the existing workpiece holders with a workpiece, ie to load them. If, for example, a total of four are provided along the direction of movement workpiece feeders that are spaced apart from one another, it can be provided that each workpiece feeder equips only a quarter of the total workpiece receptacles provided on the workpiece carrier with one workpiece each.
  • At least one of the workpiece feeders has a slide and an actuator coupled thereto in order to shift a single workpiece into one of the workpiece holders.
  • the actuator can have a hydraulic or pneumatic cylinder, for example, and can move the slide along an assembly or insertion direction or in the opposite direction thereto.
  • a single workpiece can be in the contact position with the slide or can come into contact with it.
  • the actuator can be activated and the workpiece can thus typically be moved into the workpiece holder. For example, push the workpiece into the workpiece holder using the slide.
  • the actuator can be moved reversingly together with the slide, i.e. against the direction of insertion into a basic position, so that another workpiece can engage with the slide, for example.
  • the actuator together with the slide can again cause the workpiece in question to be shifted into a further workpiece holder to be fitted.
  • the activation of the actuator, and thus the displacement movement of the slide is typically carried out by means of an electronic controller, so that all workpiece holders of the workpiece carrier can be equipped with workpieces as intended.
  • all workpiece feeders each have a slide and an actuator coupled thereto in order to feed the workpieces provided there into the corresponding workpiece holders of the workpiece carrier relocate, such as pushing or pushing into the corresponding recordings.
  • the individual actuators of the workpiece feeder can be actuated or activated in a coordinated manner by means of the controller in order to ensure that the individual workpiece holders of the workpiece carrier are each occupied with only a single workpiece.
  • the workpiece feed device has at least one sensor, by means of which a position or attitude of the workpiece carrier can be determined or measured.
  • the sensor can be used to precisely determine the mutual alignment or positioning of the workpiece holders relative to the respective workpiece feeder in the area of the first position and/or in the area of the second, possibly also in the area of the third position.
  • Signals from the sensor can be evaluated by the central electronic controller, for example, in order to activate the respective workpiece feeder, in particular its actuator, depending on the position of the workpiece carrier, so that individual workpiece holders can be equipped with one workpiece each.
  • the position and/or position of the workpiece carrier can be determined either absolutely in space or in relation to a reference system of the grinding machine, but also in relation to the workpiece feeders of the workpiece feed device, if necessary.
  • the sensor can be, for example, a rotation angle sensor or have a corresponding rotation angle sensor.
  • Such a sensor can be used to determine the position, setting or orientation of the workpiece carrier relative to the first or second position, or relative to the first or second workpiece feeder.
  • the workpiece feeders are triggered or activated as a function of signals from the sensor in order to relocate individual workpieces with a precise fit into the workpiece holders of the workpiece carrier provided for this purpose.
  • the workpiece feed device also has a controller which is coupled to at least one of the workpiece feeders.
  • the controller is designed to activate the at least one workpiece feeder depending on a position or setting of the workpiece carrier for moving a workpiece into an associated workpiece holder.
  • the controller which is typically designed as an electrical or electronic controller, can be coupled in particular to the sensor in terms of data technology.
  • Sensor signals from the sensor which define or indicate the current setting or position of the workpiece carrier and thus also the relevant position or alignment of workpiece holders provided on the workpiece carrier relative to the workpiece feeders, can be used to activate or trigger the individual workpiece feeders by means of the controller.
  • the controller can also be data-technically coupled to a drive of the workpiece carrier.
  • the drive of the workpiece carrier can be designed to be controllable or adjustable by means of the controller.
  • the position or location information of the workpiece carrier that is necessary for activating individual workpiece feeders can also be generated or determined via the drive of the workpiece carrier.

  • the position of the individual workpiece feeders can be matched to the position of the workpiece holders on the workpiece carrier in such a way that all workpiece feeders can be activated simultaneously or synchronously by the controller.
  • a single control signal could also be used to activate or control several or all of the workpiece feeders.
  • each of the workpiece feeders has a slide and an actuator in order to displace workpieces that have been supplied or are to be supplied into a respective associated workpiece receptacle of the workpiece carrier.
  • the senor is linked to the controller in terms of data technology. Signals from the sensor or the workpiece carrier drive, which characterize the setting or position of the workpiece carrier, can thus be forwarded to the controller for signal evaluation. As a result of the signal evaluation, the individual workpiece feeders, in particular their actuators, can then be activated individually or coordinated with one another.
  • the controller is coupled to each of the workpiece feeders and designed to activate the individual workpiece feeders depending on the position of the workpiece carrier and/or in a coordinated manner.
