Definitions

  • the present invention relates to the manufacture of brushes and, more particularly, is directed to an apparatus for automatically inserting tufts of bristles into a brush body.
  • the invention is particularly concerned with an automatic control system for such apparatus.
  • the individual operational steps to be controlled of such apparatus comprise primarily (a) The grasping of a number of tuft-forming bristles from a stock and feeding the same toward the tuftsetting means,
  • FIG. 1 is a diagrammatic illustration of a tuft-setting apparatus with a control mechanism according to the present invention.
  • FIG. 2 is a modified tuft-setting apparatus according to the invention.
  • FIGS. 3 to 8 illustrate the tuft-setting tool in the subsequent working positions of its single parts.
  • the tuft-setting apparatus of the present invention is characterized primarily by a fluid operable control mechanism as for instance a pneumatically operable control mechanism or a hydraulically operable control mechanism.
  • a fluid operable control mechanism as for instance a pneumatically operable control mechanism or a hydraulically operable control mechanism.
  • the employment of fluid operable means for controlling the various control operations imparts upon the operation of the apparatus a heretofore non-obtainable smoothness, without affecting the precision of operation. In this way, the wear of the tools for carrying out the individual operational steps Will be considerably reduced and thus the life of the apparatus will be increased While its liability to disturbances will be greatly decreased.
  • Standard switch and control elements may be employed for the individual movements of the tools. The respective location of these switch and control elements may be selected in conformity with the particular requirements and the pneumatic or hydraulic connections may be effected in any convenient manner by hoses or the like. It is furthermore possible in view of the filuid pressure control of the present invention to combine a greater number of tools to an automatic brush-producing unit
  • control of the pneumatic or hydraulic tool drives may be effected by a single control member common thereto such as for instance a cam shaft the cams of which actuate control elements for the individual drives.
  • the pressure fluid driving and controlling means for bringing about the individual Working operations may also be arranged in series in such a way that each working step will control or initiate the next working step. Such an arrangement will assure the proper sequence of operation of the various operational steps and will further reduce the possibility of any disorders.
  • the course of the movements associated with each working operation may, according to the invention, be controlled in conformity with the movement of the work piece.
  • the start of the working operations may be controlled by the stepwise effected feed of the brush body to be provided with tufts of bristles.
  • While the working speed of the tools in an apparatus according to the invention is less than that of a mechanically controlled apparatus of the type involved, this can be more than compensated for in a fluid pressure operated device according to the present invention by providing a sufiicient number of pressure actuated tools, and above all in corresponding arrangement along the path of the brush body, preferably so that with each feed step of the work piece conveyor, the machine will deliver a completed brush at its discharge end.
  • FIG. 1 and FIGS. 3 to 8 the arrangement shown therein comprises primarily a first portion with the actual tools and a second portion representing the control mechanism according to the invention.
  • Said first portion which comprises to a great extent a mechanism known per se, is designed as follows.
  • a setting needle 3 which is actuated and guided by the piston 4 and is furthermore guided in a transverse wall 5.
  • a slide 6 which is connected to a setting head 8 by means of an arm 7 firmly connected to said head and extending through the wall of said housing.
  • the said tool head 8 is coaxially connected to the setting needle 3 and is provided with a longitudinal bore for the latter.
  • the head 8 is located in front of one end face of housing 2 and is displaceable so as to be able to be brought into engagement with a work piece 1.
  • a spring 9 Between the needle piston '4 and slide 6 in housing 2 there is mounted a spring 9, whereas between said slide 6 and the transverse wall there is interposed a spring 10.
  • the feed of the tool head 8 may also be effected by a separate fluid compressed actuating drive.
  • the apparatus or working tools thereof include a device 11 for grasping and feeding a certain quantity of bristles.
  • This device which has the shape of a sickle, is provided with a recess 12 and is adapted to oscillate.
  • said sickle 11 When said sickle 11 is oscillated outwardly (FIG. 1), it will from the stock container 13 grasp a certain quantity of bristles, hairs or the like and will convey the same to the station a between the end face of housing 2 and the setting head 8 (FIG. 5).
  • the following means are employed for purposes of forming the anchoring loop from wire or in order to apply the anchoring loop to the withdrawn tufts of bristles to be set.
  • the mandrel 19 is displaceable on rod or bar 20 and in a direction transverse to the housing 2, which direction is in fact (as shown in FIGS.
  • the fluid pressure operated mechanism of the tuftsetting apparatus comprises the following elements (FIGS. 1 and 2).
  • a fluid pressure cylinder 22 with double acting piston 23 said cylinder 22 being journalled so as to be adapted to oscillate.
  • piston rod 24 of piston 23 is pivotally connected to sickle 11.
  • the stepwise feed of wire 17, in the form shown in FIG. 1, is effected by a piston rod 26a connected to the piston 26 which is reciprocably mounted in a pressure fluid cylinder which is journalled so as to be able to oscillate.
  • the drive of the cutting and bending tool 1 8 is effected by a cylinder 27 having a double acting piston 28 reciprocably mounted thereon, while piston rod 29 connected to piston 28 is connected to bar or arm 21.
  • the setting needle 3 extends outwardly through the rear end of housing 2 and is connected to a double acting piston 32 reciprocably mounted in a cylinder 31.
  • the rod 20 is driven by a piston 35 which is reciprocably mounted in cylinder 36.

  • the switch 38 is by means of lines 39 leading to a switch 40 electrically connected with an electric motor 41.
  • Motor 41 through a worm wheel gear system 4 2 drives a control shaft 43 which has mounted thereon in certain offset arrangement five cam discs 44, each cam or disc 44 being offset -to the next one in a certain manner.
  • Each of the cams is adapted to actuate a pressure fiuid controlling switch 45 to 49.
  • a brush body 1 taking part in said Work piece feeding movement closes switch 38 thereby closing the energizing circuit for the electric motor 41 so as to start the same.
  • the switch 41 in line 39 represents a time switch determining the time for which the motor 4 1 thus started will remain in operation. This period controlled by switch 40 is so selected that the cam shaft 43 will carry out precisely one complete revolution in the direction of the arrow b.
  • the cam surfaces of the cam discs 44 respectively control the switches 45 to 4% associated therewith in the direction of advance and return of the pistons of the respective cylinder piston systems controlled thereby. This is effected in the sequence determined by the offset arrangement of the cams. Inasmuch as said sequence is determined in conformity with the sequence of the movement of the individual parts of the apparatus, it will be evident that with each complete rotation of cam shaft 43 a complete series of setting operations or a complete setting cycle will be effected.
  • each switch 45 to 49 has connected thereto a number of tool drives, for instance for as many tools as are required for the simultaneous setting of a brush body.
  • the common control range may be broadened by a correspondingly extending shaft 43 and mounting thereon a number of groups of cam discs 44 and associating therewith a corresponding number of switches 45 to 49. If a larger tuft-setting machine is to be produced, the entire control mechanism from motor 41 on up to switches 45 to 49 may be multiplied and all control means may be controlled parallel to each other by a work piece switch 38 common thereto.
  • FIG. 2 differs from that of FIG. 1 with regard to the control of the individual working operations which in this instance are controlled in series.
  • the fluid pressure operable drives of the parts of the apparatus are supplemented in such a way that the piston rod 29 is provided with a dog or nose 30, while the piston rod 3 is equipped with a finger 3-3, and rod 20 is provided with a nose 37.
  • switches 50, 5 1 and 52 are respectively arranged in the path of said noses and finger.
  • Cylinder 31 is preceded by an impulse valve 34.
  • Cylinder 22 is journalled so as to be able to oscillate.
  • a double lever 53 is adapted to take part in the oscillating movement of cylinder 22.
  • the said double lever 53 is adapted by means of a push rod 54 engaging the gear ring 16 to actuate stepwise the pair of rollers .14, 15 in such a Way that each time a wire piece of the length of the desired loop is fed into the housing 2.
  • Switch 55 is arranged in the path of the oscillating lever 53.
  • the control member 38 which in this instance operates pneumatically, is actuated by a brush body passing by switch 38, the said switch 38 will in its switched-on position pass compressed air received from a main conduit 59 and conduit 6%, through a conduit 61 to the cylinder piston system 22, 23 operatively connected to the sickle 11.
  • said sickle 11 will convey a certain quantity of bristles from container 13 to station a.
  • the pair of rollers 14', 15 will, through the intervention of the lever system 53, 54, move a piece of wire .17 into housing 2.
  • the oscillating lever 53 will by means of its free end actuate switch 55 so that the latter will through conduit 63 actuate the cylinder piston system 27, 28 for the cutting or bending tool 18 so as to cause the same to bend the wire loop 1% around mandrel 19.
  • the control nose 3% of piston rod 29 closes a switch 50 as a result of which pressure fluid passes through conduit 54 to cylinder 36 and actuates piston 35 so as to withdraw or return bar 20 to its starting position.
  • nose 37 of bar 24 actuates switch 52 designed as valve with idle return and adapted to release the compressed air through a conduit 66 to the impulse valve 34.
  • Valve 34 controls a cylinder piston system 3'1, 32 in such a way that the setting needle 3 is instantaneously advanced whereby due to the follower effect of spring 9 first the tool set 8 containing the wirelooped tuft 13a of bristles is in a shock-like manner pressed against the brush body 1 while during the further stroke of piston 32, the setting needle 3 pushes or drives the tuft 14a of bristles into the receptive bore 67 of the brush body 1.
