  • the present invention relates to projection blowpipes employing rods or bars and more particularly a device for automatically feeding rods or bars to such blowpipes.
  • this automatic feed device comprises in combination, a feed support on which said rods are disposed in parallel relation to each other and which is movable in a step-bystep manner so as to present the rods in succession in a given position in alignment with the biowpipe, a device for pushing the rods and engaging them in the blowpipe, and a device for shifting the support when a consumed rod leaves said support.
  • FIG. 1 is a front perspective view of the device according to the invention.
  • FIG. 2 is a rear view thereof
  • FIG. 3 is a perspective view of the underside of the feed support showing the device which shifts the latter in a step-by-step manner
  • FIG. 4 is a diagram showing a detail of the device for pushing the rods.
  • the feed device according to the invention is designed to feed rods in a continuous manner to a conentional blowpipe of the projection or jet type which is shown diagrammatically at C and comprises two knurled driving wheels M and M which feed the rods in a regular manner into the gun of the blowpipe in the usual way. These wheels are rotated by an electric motor (not shown).
  • tube 1 (FIG.
  • a rack 6 which has offset teeth
  • This device comprises a cylindrical thrust element 7 provided with an axial bore and slidably mounted on the latter on a cylindrical bar 8.
  • the bar is secured to the stand at one end and extends in a direction parallel to the axis of the tube 1 throughout the width of and above the plate.
  • a finger 9 is fixed under the thrust element 7 and is applied against the end of the rod so as to push the latter in the direction of the blowpipe.
  • the thrust element is urged in the direction of the blowpipe by a device including a counterweight and a chain 10 which is secured at 11 to the thrust element under the bar 8, passes around a pulley 12 mounted on the free end of the bar near the blowpipe C, extends through an aperture 13 in the upper part of the thrust element and finally passes around a pulley 14 which has a spindle fixed to the stand and is spaced away from the plate.
  • a weight 15 is suspended from the free end of the chain 10 (FIGS. 1 and 2).
  • a return device comprising a lug 16 fixed to an endless belt 17 mounted on two pulleys 18 and 19.
  • One of the pulleys, 18, is mounted on the stand in the vicinity of the pulley 12 of the bar 8 and the other is mounted on the shaft of an electric motor M, secured to the stand in the vicinity of the other end of the bar 8.
  • the lug '16 bears against the forward face of the thrust element as shown in FIG. 4.
  • the feed device also comprises means for shifting the plate in a step-by-step manner so that a groove 2 carrying a rod places itselft exactly on the axis of the tube 1 when a consumed rod has left the plate.
  • This device comprises a rack 6 (FIG. 3) which includes two rows of teeth, 20 and 21, offset from each other, the offset between two successive teeth of each row corresponding exactly to the distance between the axes of two successive grooves. In other words, the space between two consecutive teeth 21 and 22 of the rack is equal to one half of the distance between the axes of two successive grooves of the plate.
  • the shifting device also comprises a retaining finger 22 mounted in such manner as to be movable along the teeth of the rack without leaving the latter and thus pass from one tooth to the other in accordance with the direction of its movement owing to the offset between successive teeth.
  • This finger is rigid with a tube 23 which is alidably mounted on a fixed bar 24 extending under the plate P and supported at its end in the vicinity of the blowpipe by an element fixed to the stand (not shown).
  • the end of the tube which is the nearest to the blowpipe is connected in a resilient manner to the bar 24 by a spring 25 (FIG. 3).
  • Fixed to the other end of the tube spaced from the plate is an abutment plate 26 which extends upwardly and against which the rear part of the thrust element 7 is capable of abutting (FIG. 3).
  • the feed device also comprises electric means automatically controlling the devices described hereinbefore. These means are shown diagrammatically in FIG. 2 and comprise:
  • a switch C which has a spring return, is normally open and disposed with respect to the plate in such man ner as to be closed by the thrust element 7 when a rod which has been almost completely consumed has left its groove.
  • This switch is connected by a conductor 30 to one J! of the terminals of the motor M and by a conductor 31 to a supply conductor 32 leading to a source of current.
  • a normally closed switch C placed on the same side of the plate P so as to be opened by the lug 16 when the latter is moved by the motor M. This switch is connected to the same terminal of the motor M as the switch C by a conductor 33 and to the supply conductor 32 by a conductor 34.
  • a conductor 33 connects the second terminal of the motor M to the conductor 37.
  • the plate P is in such position that a rod E placed in a groove 2 is in process of being consumed by a blowpipe C.
  • the plate P is locked in position by the retaining finger 22 against which a tooth 20 of the rack 6 abuts, the spring 25 maintaining the tube 23 in its extreme left position as viewed in FIG. 3.
  • the finger 9 of the thrust element 7 is held against the free end of the rod by the action of the weight but the rod is fed forward by the wheels M and M of the blowpipe.
  • the lug 16 of the endless belt 17 is normally in rest and abuts the switch C which is opened so that the motor M does not operate.
  • the finger 22 passes from one tooth 20 to the following tooth 21 of the rack owing to the offset arrangement of these teeth and to the action of the plate which moves under the eifect of its own weight and advances a distance corresponding to half a groove. Meanwhile, the lug 16, in continuing its travel, passes around the pulley 18 and releases the thrust element 7 which, under the effect of the counterweight 15, returns in the direction of the blowpipe. The retaining finger of the plate then returns towards the left (FIG.
  • the device Owing to the device according to the invention, it is possible to provide an extremely interesting automatic projection system avoiding any manual intervention in the course of operation and causing no disturbance of the operation of the blOWpipe itself whose settings remain same.
  • the device can be mounted on any type of projection blowpipe. This device permits avoiding hasty manipulations of rods which might be very fragile. They could be mounted on the plate before the latter is engaged in the slideways. In this Way it is also possible to effect remote-controlled projections under glove boxes or in a special atmosphere.
  • Automatic feed device for projection blowpipes fed with rods or bars, said device comprising in combination a movable feed support for receiving thereon said rods in parallel relation to each other, means for moving the support in a step-by-step manner for presenting the rods in succession in a given position in alignment with the blowpipe, a device for pushing the rods and engaging them in the blowpipe and a device for shifting the support when a rod about to be completely consumed leaves the support, said support being a plate having on the top face thereof parallel grooves for receiving the rods, the plate being slidably mounted in slideways and inclined so that it moves solely under the effect of its own weight.
  • the device for shifting the support comprises a rack fixed under the bottom face of the plate and comprising successive teeth offset from each other, the successive teeth being spaced from each other a distance equal to one half the distance between the axes of two consecutive grooves of the plate, and a movable retaining device comprising a finger capable of moving from one tooth to the next of the rack 5 under the successive opposed actions of the device for pushing the rods and of a return device.
  • the plateretaining device comprises an abutment rigid with said finger and against which the thrust element bears in the course of the return movement of the latter to its initial position, and a return spring for returning the finger and the abutment when the thrust element no longer acts on said abutment, the arrangement being such that the plate advances a distance corresponding to half the distance between two grooves when the finger moves in one direction and the same distance when the finger moves in the other direction, whereby the plate presents a new rod in front of the blowpipe When the thrust element is once again in position for pushing the rod.
