Definitions

  • This invention concerns an automatic button fiedlng device in machines for sewing on but-' Automatic feed devices are known, which have a funnel-shaped magazine or hopper with a cy-.
  • buttons are introduced into a tongs arrangement and by means of this tongs arrangement they are brought below-the needles of. an automatic button sewing machine. .Now since, as follows from the law of probabilities, it may frequently occur, that the buttons which are thrown haphazard into the funnel will, in passing through the cylindrical part, reach the guide plate in an incorrect posi-- tion, the known arrangement is provided with a special turningdevice which turns the buttons which have fallen incorrectly before they are pushed .into the tongs arrangement.
  • the exceedingly complicated turning arrangement which does not always function reliably is avoided by the provision in the bottom outlet plane of the cylindrical. tube of two pusher members which are capable of being moved in two diiferent radial directions.
  • These pusher members are controlled by cam drives in such a manner that the buttons which reach the guide plate in the correct position are pushed into gripping tongs, whilst the buttons which fall incorrectly are pushed oil the guide plate.
  • For controlling the pusher members separate feeler levers are provided.
  • FIG. 1 shows a side view of the device diagrammatically Fig. 2 a portion of the same device with the bottom button inthe wrong position
  • Fig. 3 a partial plan view of the same device
  • Fig. 4 a partial side view on line A-B of Fig. 3 and Fig. 5 a portion of the ieeler lever to.a larger scale.
  • the device consists of a feed magazine comprising an upper funnel-shaped widening 2 and a cylindrical guiding part 3. At both sides, diametrically opposite one another, there are riveted to the cylindrical wall retaining hooks l, the hook-shaped ends 5 of which are normally flush with the edge of the bottom opening or the cylindrical part 3.
  • the hooks 4' consisting or arranged to rock about the pivot 9.
  • buttons which are deposited in the funnel 2 and lie piled in'the cylindrical guiding part with their main surface parallel can leave freely at the bottom, without being obstructed Y a by the hooks.
  • buttons I falling out of the guiding cylinder 3 rest.
  • the two hooks l are moved towards one another by means of two pressure applying pins 8 operated by an automatieally acting mechanism, not-shown in the drawing.
  • the sharp ends of the hooks whichare bent over about at a right angle, can penetrate between the more or less rounded edges of the buttons, so that there is no danger of" the hooks striking against the side of the buttons and not being able to enter between the button edges.
  • the pile of buttons lying above the hooks, of which only three buttons are shown diagrammatically in the drawing, is thus prevented from dropping prematurely down as far as the guide plate 6.
  • the feeler head H of a two-armed feeler lever In the y de plate 6 there is provided, concentric wi V the axisof the guiding cylinder, an I opening it, through which can pass the feeler head H of a two-armed feeler lever.
  • Ill which is button 1 be in the correct position, that is to say', if its upper side be directed upwards, the feeler head II can enter so far into the opening l2- that'it will be flush-with the upper surface of the-guide.
  • plate 8 (position shown in Fig. 1). In this position the other end of the feeler lever It is opposite the opening l3 of the driver It.
  • the driver I4 is fixed to the bar I! of a pusher member' I! which is moved by way ofa forked frame I! by a cam disc It, the roller 20 of the fork being pressed by a spring l9 against the cam disc It.
  • prongs 21 is moved in the direction of the arrow a by any arrangement of a kind known per se in connection with automatic devices and not shown in the drawing.
  • pins are arranged face of the button, until the pin points penetrate into two oppositely disposed holes 25.
  • the button I is carried round, until, after completing the half revolution, it is taken into the desired position, in which the holes in the button have the correct position with respect to the needles of the sewing machine of a kind known per 'se, which is not shown in the drawing.
  • the tongs arrangement with the button is only then brought under the button sewing machine and the button is automatically sewn on by it.
  • a button should have entered the guiding cylinder 3 in the wrong position and consequently have also reached the guide plate 6 in the wrong position (the position shown in Fig. 2), the'head II of the feeler lever II! can enter the depression Iaof the button, causing the feeler lever I to rock about the pivot 9, so thaw the outer lever end is swung out of alignment with the opening I3 in the driver member.
  • This incorrectly placed button is then pushed by another pusher member I5a, which is arranged at about 90 to the sliding member I5 (Fig. 3), oil the guide plate 6 into a receptacle (not shown in the drawing and is transferred as required back to the funnel 2.
  • the motion of this pusher member I5a. is released by a feeler lever IIia which beers with its feeler end Ila against the endxof the first-named feeler lever Id.
  • the head part Iiib of the feeler lever 'IQ is drawn by a cam drive 29, a two-armed lever 29a and a link member 30 out ofthe depression.
  • the feeler lever I0 is made in two parts (see Fig. 5).
  • the striking part of the feeler lever is provided at its pivot eye M with a finger 32, against which bears under the action of a spring 33 the feeler arm IOb of the feeler lever I0, which is capable of rocking about the same pivot pin 9.
  • the spring is made of such strength that with normal feeling motions the entire feeler lever will act in the manner of a rigid lever. only when the cam drive 29 acts on the feeler lever arm 33 will the head part lib be rocked with respect to the striking part of the feeler lever, the spring I! being tensioned.
  • the lever Ilia is made in two parts in a similar manner. It is normally held in the extended position exactly like the lever III by a spring "a.
  • the cam drive 29 (Fig. 2) moves with respect to the cam disc Ila in such a manner that the drawing downwards oi the head part IOb of the lever ilionly commences, when the pusher member Ida has already moved a certain distance towards the button 1, without however having come in contact with the button. The result of this is, thatthe feeler end of the lever Illa will already have entered the opening Ila. 0n the head part III?) being drawn downwards by the cam disc I!
