Definitions

  • the invention relates to a stacking device with the Features of the preamble of claim 1.
  • Press systems such as in particular body presses, deliver sheet metal parts in an orderly manner according to their work cycle have to be removed. Reaching press lines even in the production of very large sheet metal parts, such as motor vehicle side walls, Doors or other sheet metal parts, working speeds of about 15 strokes per minute.
  • sheet metal parts occurring in the same cycle must be free of damage be removed and transported away. This must be in be done in a fail-safe manner to the Do not hinder the operation of the press system. It exists often the requirement that a failure of an automatic Stacking system not at a standstill of the press system or another upstream production facility may lead.
  • the manual removal of sheet metal parts for example Can weigh 50 kg and be released every 4 seconds, is not easily possible. A failure of an automatic The stacking system is therefore usually at a standstill upstream production facility.
  • the stacking device has a removal transport device on the parts from an upstream system, e.g. sheet metal parts delivered by a press system, and feeds a switch.
  • the switch serves two or more connected stacking transporters that alternate be supplied with sheet metal parts. This gives everyone Stacking device only a fraction (the Half or less) of the total from the removal transport device adopted sheet metal parts.
  • Each stacking transport device transports the Sheet metal parts each to a stacking place at which the sheet metal parts then removed and stacked, for example on pallets become.
  • Appropriate gripper devices can be used for this, the sheet metal parts from the stacking conveyor remove and place them on pallets.
  • the sheet metal parts come on the stacking transport device with a lower repetition frequency when they are removed from the system, e.g. the press system, be delivered. As a result of the reduced frequency can be removed by hand if necessary and in an emergency and are stacked ("stacked"), whereby even at Failure of the gripper devices to operate the upstream Press system can be continued.
  • the stacking conveyor has at least one Section that temporarily stops. This makes it possible a downstream automatic gripper device, as well as auxiliary personnel, the sheet metal parts to take and orderly to take off and put down.
  • the upstream switch which is the number of sheet metal parts arriving (frequency) per unit of time reduced, it becomes possible even at high working speeds the press system (15 strokes per minute) and relatively large and thus also manually stack heavy sheet metal parts, to operate the press system in special situations to be able to continue. So overall availability elevated.
  • the removal conveyor, the stacking device and / or the switch conveyor can each be designed as a conveyor belt his. This has the advantage that there is no adjustment to it different sheet metal parts is required. Furthermore is a position-independent, gentle transport of the sheet metal parts ensured.
  • the removal conveyor and the stacking conveyor i.e., the treadmills of the take-out conveyor and the destacking device preferably run at least temporarily at the same speed. This is again preferably in line with the conveying speed the switch matches, which ensures a good transition of the sheet metal parts from the removal conveyor to the switch and from the Switch on the stacking conveyor is ensured.
  • the removal conveyor runs, for example. in start / stop mode and only has to hand over sheet metal parts the switch has the same transport speed as this.
  • the average running speed of the removal conveyor is lower than that for start / stop operation the soft.
  • the same applies to the average speed of the destacking conveyor for example have a uniform conveying speed and thus can be driven as a whole in the start / stop mode.
  • the Average speed of the stacking conveyor then less than that of the switch. This also applies if only a section of the stacking conveyor in the Start / stop operation is driven. For example, it can are sufficient, the end of the stacking conveyor located away from the switch to operate in start / stop mode in order to to enable an orderly acceptance of the sheet metal parts and do not accelerate and brake the entire conveyor to have to.
  • the average speed of the stacking conveyor be less than that of the removal conveyor.
  • the low average speed the stacking conveyor both facilitates manual stacking as well as automatic access by robots.
  • FIG. 1 A stacking system 1 is illustrated in FIG. 1, which is used by a press system 2 Sheet metal parts to two stacking locations spaced apart 3, 4 and then stack them there.

  • the removal transport device 4 has one Drive device 8, which drives the conveyor belt 5 serves. This is guided over at least two pulleys, at least one of them through the drive device 8 is driven.
  • the drive device thus determines the Conveying speed of the conveyor belt 5, the drive device 8 is subject to the control of a control device. This gives the running speed of the conveyor belt 5, the starting or stopping of the same.
  • the control device can in turn not be further illustrated by Sensors controlled the positions the parts 6, 7 on the conveyor belt 5.
  • a switch 9 is provided, which is also used as a belt conveyor is executed.

This can create a spatial Separation or unbundling of those separated by the switch 9 Funding channels can be achieved. So individual, each stacking spaces occupying a considerable space in one Hall should be arranged so that each other do not interfere with each other at the stacking places or disturb.
  • the stacking transport device 18 is at a distance arranged under the stacking transport device 17, the Permitted passage of curved sheet metal parts 6.7. She is designed as a belt conveyor and with a conveyor belt 23 provided. A drive device is used for the drive 24, the desired speed of the conveyor belt adjust and start and stop it specifically can.
  • Both drive devices 22, 24 are subject to one Control that can be connected to sensors that control the The position of the sheet metal parts 6, 7 and the control device Report.
  • the control device controls the conveyor belts 19, 23 accordingly, so that conveyor belts at least always have a matching conveying speed, when a sheet metal part from a conveyor belt onto the the following conveyor belt is handed over.
  • the conveyor belts 19, 23 are immediately adjacent to that End 15 of the switch 9 in the upper or lower position on.
