Definitions

  • the invention relates to a device for sorting waste parts of workpieces on saws, preferably on optimizing chop saws, according to the preamble of claim 1 and a method for sorting out waste parts of workpieces on saws according to the preamble of claim 13.
  • the invention has the object of providing the generic device and the generic method in such a way that the rejection of the waste parts can be performed with high performance and accuracy.
  • the workpiece parts separated by the saw are accelerated away from the saw area by means of the acceleration roller, so that successive sawed-off workpiece parts can be transported rapidly one after the other through the device.
  • the acceleration ensures that the workpiece particles are conveyed reliably.
  • the device has a conveyor track 1, on which the workpieces 2 to be sawn are fed to a saw 3.
  • the conveyor track 1 is formed by adjacent transport rollers 4, which are freely rotatably mounted about horizontal axes.
  • the feed roller 6 is a measuring wheel 5 downstream, which is like the feed rollers 6, 11, 12 rotatable about a horizontal axis.
  • the measuring wheel 5 has a larger diameter than the feed roller 6 and is not driven.
  • the feed rollers 6, 11, 12 are rotatably driven by a respective drive 9.
  • the drives 9 can be operated independently.
  • the feed rollers 6, 11, 12 are adjusted so that they rest on the workpiece 2, so that it can be reliably fed to the conveyor track 1 of the saw 3.
  • the saw 3 has a (not shown) saw blade, which is moved in the embodiment from bottom to top during the sawing process.
  • the saw blade dips into a housing 10, under which the workpiece 2 moves through.
  • the saw 3 is provided in front of and behind the saw blade, each with a feed roller 11, 12 which are rotatably driven about mutually parallel horizontal axes.
  • Both feed rollers 11, 12 advantageously have the same diameter and, like the feed roller 6, can advantageously be adjusted to the thickness of the workpieces 2.
  • Below the feed rollers 11, 12 are further transport rollers 13 on which the workpieces 2 can be reliably transported.
  • the hold-down 14 In the transport direction of the workpieces 2 behind the saw 3 is at least one hold-down 14 which holds down the sawn workpiece parts during removal by an endlessly circulating sorting belt 15.
  • the saw 3 facing the end of the blank holder 14 is formed obliquely upward, so that the sawn workpiece parts 2 'reliably under the Downholder 14 arrive.
  • the hold-down 14 is plate-shaped and can be adjusted in height transversely to the sorting belt 15. It is also possible to adjust the hold-down 14 parallel to the sorting belt 15. In this way, the hold-down 14 can be optimally adjusted to the workpiece parts 2 'to be transported.
  • the hold-down 14 is provided on a support device 16, on which the drives for height and / or transverse adjustment of the hold-down 14 are provided.
  • two sorting rollers 17, 18 are present in the embodiment, which can be adjusted independently of each other in height.
  • actuating cylinders 19, 20 are provided on the support device 16, with which the sorting rollers 17, 18 can be adjusted to the desired extent.
  • the sorting rollers 17, 18 protrude through openings in the holding-down device 14.
  • the setting cylinders 19, 20 By actuating the setting cylinders 19, 20, the sorting rollers 17, 18 are moved down to rest on the sawn-off workpiece part 2 '.
  • the saw 3 adjacent pulleys 22 for the sorting belt 15 can be adjusted in the transport direction of the workpieces 2.
  • the waste chute 21 is closed by the sorting belt 15. Due to the adjustability of the pulleys 22, the waste chute 21 can be opened partially or completely, so that in the manner to be described manner sawn waste pieces behind the saw 3 can fall into the refuse chute 21.
  • the adjustability of the pulleys 22 of the sorting belt 15 is known and therefore will not be described in detail.
  • the sorting belt 15 is driven continuously during operation of the sawing device. With the sorting belt 15, the sawn-off workpiece parts 2 'are further transported, in particular fed to a sorting device, with which the workpiece parts 2' are sorted taking into account their length.
  • the workpieces 2 are marked before the sawing process with regard to defects. This can be done manually, for example using chalk marks, but also be made automatically by scanning devices. When running the workpieces 2 in the sawing these marks are detected by a corresponding reading device and entered into the control of the device. This makes it possible to saw the workpiece 2 thus detected at the markings and to sort out the good parts 2 'by means of the sorting belt 15 and to sort out the waste parts 2 "by opening the refuse chute 21. The corresponding settings are made automatically with the aid of the control.
  • the method sequence will be explained by way of example with reference to FIGS. 2 to 5.
  • the conveyor track 1 with the transport rollers 4 is preceded by a (not shown) transport device, which is advantageously formed by an endless circulating conveyor belt on which the workpieces of the feed roller 6 are supplied. It detects the workpieces 2 and leads them to the subsequent saw 3.
  • the workpiece 2 is taken over by the two feed rollers 11, 12 associated with the saw 3, which are rotatably driven and transport the workpiece 2 into the desired position.
  • the drive of the feed rollers 11, 12 is interrupted, thus positioning the workpiece 2 in the saw 3. Subsequently, the saw cut is made at the cutting position.
  • Fig. 2 shows the case that the sawn-off workpiece part 2 'has only a small length. It is transported by the feed roller 11 from the saw 3 under the hold-down 14.
  • the feed roller 11 adjacent sorting roller 18 is extended downward and pressed onto the workpiece part 2 '. It is thereby pressed against the sorting belt 15 and accelerated.
  • the pressure on the workpiece part 2 ' is just set so large that it is reliably detected by the continuously driven sorting belt 15.
  • the acceleration of the sawn-off workpiece part 2 'on the continuously rotating at constant speed sorting belt 15 may for example be up to 250 m / min.
  • the time until the take-up of the workpiece part 2' on the sorting belt 15 does not depend on friction factors, such as part weight, surface structure and the like.
  • FIG. 3 shows the case that the refuse chute 21 is partially opened by the corresponding guide rollers 22 have been moved back for the sorting belt 15. This movement of the guide rollers 22 can be done even before the sawing process, since before entering the workpiece 2 in the sawing device, the cutting positions at which must be sawn, have been read into the controller. On the basis of this read data, the corresponding adjustments of the machine parts can be made.
  • FIG. 3 shows that the sawn-off workpiece part 2 'is longer than in the exemplary embodiment according to FIG. 2. The workpiece part 2' is so long that, despite partially opened waste chute 21, it reaches the sorting belt 15 and does not fall into the opened waste chute 21.
  • the sorting roller 17 lying away from the feed roller 11 is pressed by means of the adjusting cylinder onto the workpiece part 2', which is carried along by the sorting belt 15 and specifically accelerated in the manner described.
  • Fig. 4 shows the case that a waste part 2 "containing a defect is sawn in the saw 3. After it has first been positioned relative to the saw blade by means of the feed rollers 11, 12 and then sawn off, it is replaced by the one after the sawing process again driven feed roller 11 is transported and falls into the open refuse chute 21. The sorting belt 15 is only moved back so far that the waste part 2 "can fall into the refuse chute 21.
  • the waste chute 21 can be opened very early, without the risk that the workpiece part 2' accidentally falls into the waste chute 21.
  • the drop movement takes place in the waste chute 21 with the assistance of blown air, for which purpose at least one blow nozzle 23 (FIGS. 1 and 2) is provided on the carrying device 16, during which a sorting process takes place short compressed air surge exits, which supports the waste part 2 "in its falling motion.
  • the blowing nozzle 23 is located in the region between the feed roller 11 and the adjacent sorting roller 18. This waste part 2 "can be sorted out at high speed, since the previously transported good part 2 'transported faster by the acceleration and the waste chute 21 can be opened earlier accordingly.
  • the waste chute 21 can remain open, for example, if the good part 2 to be subsequently sawed is 'is so long that, despite its open waste chute 21 with its front end in the transport direction on the sorting belt 15 and is still detected with its rear end of the feed roller 11. As soon as the feed roller 11 rotatably driven and the corresponding sorting roller 17, 18 on the Good part 2 'are pressed, the sawed good part 2' over the opening area of the refuse chute 21 away transported.
  • the sorting rollers 17, 18 are moved by the adjusting cylinders 19, 20 at each good part 2 'down and pressed on the Good part 2'. Immediately thereafter, the actuating cylinders 19, 20 drive the sorting roller 17, 18 back, so that the subsequent workpiece part 2 'can reliably reach under the downholder 14.
  • the deflection rollers 22 of the sorting belt 15 is advantageously carried out by means of a servo motor, with which the sorting belt 15 and its corresponding guide roller 22 for opening and closing the waste chute 21 can be positioned.
  • waste chute it is also possible to sort out the waste parts 2 ", to use other sorting facilities, such as slides that push off the corresponding waste part 2" from the sorting belt 15 transversely.
  • the corresponding slide can be operated pneumatically, hydraulically, electrically and the like. This sorting process can be done very quickly.
  • the good parts 2 ' which have no defects, are accelerated away in the manner described after the sawing process by means of the sorting roller 17, 18 on the sorting belt 15 of the saw 3.
