Definitions

  • This invention relates to a process for selecting an off-size material during travel, and more particularly, to the selecting of off-size tubes during tube making.
  • This invention has been developed to deal with the ready and sure selection and rejectionof off-size material automatically.
  • the main features of this invention revolve around a process that measures the material length and having selecting means for comparison of the material with preset requirements.
  • Rejecting means for rejecting the off-size material' is'also combined, with the other components.
  • an object of this invention is to provide a process for selecting off-size material during travel.
  • Another object of this invention is to provide a simplc, sure and safe arrangement for selectingoff-size material during travel.
  • the present invention contemplates an arrangement for the selection of off-size material during travel.
  • the size of the material' is detected as a pulse count which is compared with a preset value corresponding to the required size.
  • Means are provided for removing the selected traveling material andtransferring it to a storage area out of the travel path.
  • FIG. 1 is an outline showing an arrangement of the detector contemplated herein in a traveling line of material
  • FIG. 2 is a schematic diagram of the electrical mechanism contemplated herein.
  • FIG. 3 is an explanatory view of the removing of an off-size material from the regular operating line.
  • FIG. 1 which is an outline of the inventive concept, shows the traveling direction of material 1, i.e., a tube.
  • a detector 3 At the end of the travel path of the tube is a detector 3 and a detector 4 of the tube which should be removed.
  • a device for removing an off-size tube and a storage area for the removedtubes At the travel path end there is also a device for removing an off-size tube and a storage area for the removedtubes.
  • FIG. 2 shows the tube traveling over carrier rolls In.
  • the pulse generator is on the axis line with carrier rolls la of the traveling tube.
  • a pulse count from a pulse generator 2 starts at the time when a detector 3 detects the front end of a traveling tube.
  • the pulse generator as shown in FIG. 2 is on the same axis asthe carrier rolls la andthe generation of pulses-depends on the rotation of the carrier rolls for the traveling tube.
  • the pulse count is memorized at a selection means 7 untilthe detector 3 detects the rear end of he tube. Then the pulse count is compared with a-preset value in-said-selection means 7. When both values agree, the traveling'tube will proceed on the regular line. If the values do not agree, which means that the tube length is either longer or shorter than the required length, the traveling tube will cause the following sequence of steps to occur.
  • An unequal signal from selectionmeans 7 is introduced to a control means 6 through a relay 8' accompanying a timer 9.
  • the control means 6 operates a solenoid valve 5 depending upon a signal from another detector 4, which detects the best suitable position when said traveling tube can be removed. Solenoid valve 5 puts a removal device 10 in operation.
  • the removed tube is handled by the means shown in FIG. 3, that is, the tube 14 is loaded on a screw conveyer 11 and then on another screw conveyer 13 across a guide table 12. These screw conveyers' II, 13 are put in motion by the action of said solenoid valve 5.
  • the off-size tube 14 is transferred to storage area 15.
  • This embodiment is used in an actual butt welded tube making process. According to many experiments, the selection and rejection of the off-size tubes was carried out automatically without any trouble. At the same time, this process may also be widely utilized in other fields, not only for the butt welded tube making process. Because the requirements of setting the pulse count, detecting the traveling of material and removal of the material may be freely changed without changing the invention concept.
  • detecting means to detect the front and rear ends of a tube
  • pulse generating means responsive to said detecting means generating a stream of pulses as said tube is detected
  • selection means coupled to said pulse generating means including timer means, for storing therein a preset pulse count with said generated pulses and f. enabling-means on said selection means enabling the turning of the screw conveyor including detector means for detecting the front and rear of said tube, timer means coupled to said detection means for fixing the size of said tube, and a relay con nected between said selection means and screw conveyor to enable said screw conveyor.
