Definitions

  • the present invention relates to a material feeding apparatus that feeds a material such as a sheet material, a wire material, etc. intermittently to a work machine such as a press apparatus, etc. a predetermined quantity by a predetermined quantity, and more particularly to a material feeding apparatus suited to feeding of a material for small-sized parts used in electronic component industry to a press apparatus at high speed with high accuracy.
  • small-sized electronic parts such as connectors, terminals, etc. are manufactured by using a material feeding apparatus to intermittently feed a material wound round a coiler to a press apparatus a predetermined quantity by a predetermined quantity to subject the same to press working (see, for example, JP-A-2004-142876 ).
  • apparatuses that intermittently feed a material such as a sheet material, a wire material, etc. to a work machine such as a press apparatus, etc. include a roll feeder that interposes a material between a main roll and a sub-roll to convey the same, a gripper feeder that interposes a material between a stationary gripper and a moving gripper being movable in a direction toward and away from the stationary gripper to convey the same, etc. (see, for example, United States Patent No. 5,720,421 and JP-A-2000-135530 ).
  • an impulse force of 10G to 20G acts in press working in a press apparatus, and when a material feeding apparatus is mounted to a press apparatus, it is necessary to firmly clamp a material feeding apparatus and a press apparatus in order to reduce influences by the impulse force. Accordingly, there is a fear that vibrations caused by an impulse force generated on a press apparatus are transmitted directly to a material feeding apparatus and such vibrations cause degradation in accuracy of feeding of a material and breakage in a location, in which a mounted state of a cover, etc. is unstable.
  • a portion possibly undergoing breakage is mounted to an apparatus, such a press apparatus, etc., in which vibrations are generated, through a vibration absorbing member (cushioning member) such as rubber, etc. (see, for example, JP-U-6-76744 ).
  • the vibration absorbing member in the related art is suitably provided in a location not affecting an accuracy of feeding of a material, for example, between a mount such as a cover, etc. and a press apparatus but not suited to use in a location, in which accuracy of feeding of a material is adversely affected.
  • the roll feeder in which a main roll is rotationally driven by a servomotor, rotation of the servomotor has direct influences on material feeding accuracy. Accordingly, there is a fear that when the servomotor and a press apparatus are clamped directly together, vibrations caused by an impulse force generated on the press apparatus act directly on the servomotor to cause degradation in accuracy of feeding of a material and breakage of the servomotor, an electric signal transmitting circuit associated therewith, etc.
  • the invention provides a material feeding apparatus according to claim 1.
  • the housing is double-structured so that vibrations caused by an impulse force acting on the outer housing are damped by the vibration absorbing member (or a cushioning member) such as a vibration proof rubber, etc. and transmitted to the inner housing. Accordingly, it is possible to effectively prevent breakage of the material feeding equipment accommodated in the inner housing, an electric signal transmitting circuit associated therewith, etc.
  • the vibration absorbing member such as a vibration proof rubber, etc. tends to be freely displaced in X-axis direction (left and right direction), Y-axis direction (vertical direction), and Z-axis (longitudinal direction), which axes are perpendicular to one another, and tends to be freely displaced in directions, which twist round the respective axes.
  • the vibration restricting member restricts the degree of freedom of vibrations, which are transmitted to the inner housing through the vibration absorbing member from the outer housing, in one direction. Accordingly, since the material feeding equipment accommodated in the inner housing vibrates only in a vertical direction, it is possible to stably perform material feeding at high speed with high accuracy.
  • the vibration restricting member preferably restricts the degree of freedom of vibrations transmitted to the inner housing in a vertical direction.
  • the vibration absorbing member includes an upper vibration absorbing member interposed between a top wall of the outer housing and a top wall of the inner housing and a lower vibration absorbing member interposed between a bottom wall of the outer housing and a bottom wall of the inner housing
  • the vibration restricting member includes an upper plate member, upper and lower surfaces of which are interposed between the top wall of the outer housing and the top wall of the inner housing, and a lower plate member, upper and lower surfaces of which are interposed between the bottom wall of the outer housing and the bottom wall of the inner housing.
  • Fig. 1 shows the alignment relationship among a material feeding apparatus 1, a press apparatus 4, and a coiler 3.
  • the material feeding apparatus 1 fixed to the press apparatus 4 is constructed so that a material 2 wound round the coiler 3 is interposed by a main roll 5 and a sub-roll 6, which constitute a material feeding equipment, and fed a predetermined quantity by a predetermined quantity intermittently to the press apparatus 4.
  • the press apparatus 4 includes metal molds 7, 8 for press working such as punching or the like. Vibrations caused by an impulse force generated on the press apparatus 4 at the time of press working are mainly directed in a vertical direction as indicated by an arrow A in Fig. 1 .
  • a housing of the material feeding apparatus 1 is double-structured to include an inner housing 9 and an outer housing 11 surrounding the inner housing 9 and connected to the inner housing 9 through vibration absorbing members (or cushioning members) 10a, 10b, 10c, 10d formed from a vibration proof rubber or the like, and the main roll 5 and the sub-roll 6, which constitute a material feeding equipment, is accommodated in the inner housing 9.
  • the main roll 5 is supported rotatably in the inner housing 9 with bearings 12a, 12b therebetween
  • the sub-roll 6 is supported rotatably in the inner housing 9 with bearings 13a, 13b therebetween
  • a servomotor 14 is connected to the main roll 5.
  • the material feeding apparatus 1 is constructed such that the main roll 5 and the sub-roll 6 interpose therebetween the material 2 and the servomotor 14 rotationally drives the main roll 5 in an intermittent manner to convey the material 2 in a direction of an arrow B in Fig. 3 to feed the material 2 a predetermined quantity by a predetermined quantity to the press apparatus 4 in an intermittent manner.
  • a material feeding apparatus of a type in which a pair of rolls interpose and convey a material, is usually provided with a mechanism that operates in synchronism with the operation of a press apparatus to release an interposing force, applied to the material by the pair of rolls, just before press working, and a mechanism that adjusts a clearance between the pair of rolls according to the thickness of the material. It suffices to appropriately adopt a known construction for these mechanisms.
  • a vibration restricting member that restricts the degree of freedom of vibrations, which are transmitted to the inner housing 9 through the vibration absorbing members 10a to 10d when an impulse force acts on the outer housing 11, in one direction.
  • the vibration restricting member includes an upper plate member 15, upper and lower surfaces of which are interposed between a top wall 11a of the outer housing 11 and a top wall 9a of the inner housing 9, and a lower plate member 16, upper and lower surfaces of which are interposed between a bottom wall 11b of the outer housing 11 and a bottom wall 9b of the inner housing 9 and which is arranged in parallel to the upper plate member 15.
  • the vibration absorbing members 10a to 10d comprise upper vibration absorbing members 10a, 10b interposed between the top wall 11a of the outer housing 11 and the top wall 9a of the inner housing 9, and lower vibration absorbing members 10c, 10d interposed between the bottom wall 11b of the outer housing 11 and the bottom wall 9b of the inner housing 9.
  • the upper plate member 15 is interposed between neighborhoods of both axial ends of an inner surface of the top wall 11a of the outer housing 11 and an outer surface of an upper plate member mount 9a' formed in the vicinity of an axial center of the top wall 9a of the inner housing 9 and fixed to the top wall 11a of the outer housing 11 and the top wall 9a of the inner housing 9 by bolts 17a, 17b, 17c.
  • the lower plate member 16 is interposed between neighborhoods of both axial ends of an inner surface of the bottom wall 11b of the outer housing 11 and an oxter surface of a lower plate member mount 9b' formed in the vicinity of an axial center of the bottom wall 9b of the inner housing 9 and fixed to the bottom wall 11b of the outer housing 11 and the bottom wall 9b of the inner housing 9 by bolts 18a, 18b, 18c.
  • the upper vibration absorbing members 10a, 10b extend through the upper plate member 15 and are mounted between the top wall 11a of the outer housing 11 and the top wall 9a of the inner housing 9. Also, the lower vibration absorbing members 10c, 10d extend through the lower plate member 16 and are mounted between the bottom wall 11b of the outer housing 11 and the bottom wall 9b of the inner housing 9.
  • Figs. 7A to 7C show the alignment relationship among the lower plate member 16, the lower vibration absorbing members 10c, 10d, and the lower plate member mount 9b' of the bottom wall 9b of the inner housing 9.
  • the lower plate member mount 9b' is formed to have a smaller length than a width W of the inner housing 9 to enable providing the lower vibration absorbing members 10c, 10d one by one on respective sides of the lower plate member mount 9b'.
  • the lower plate member mount 9b' can have substantially the same length as the width W of the inner housing 9 to stabilize flexural deformation of the lower plate member 16 when vibrations apply.
  • Fig. 7C shows a modification of the construction shown in Fig. 7A , in which lower vibration absorbing members 10c, 10d are provided two by two on respective sides of the lower plate member mount 9b'.
  • the upper plate member 15, the upper vibration absorbing members 10a, 10b, and the upper plate member mount 9a' of the top wall 9a of the inner housing 9 can be arranged in the same manner as that, in which the lower plate member 16, the lower vibration absorbing members 10c, 10d, and the lower plate member mount 9b' of the bottom wall 9b of the inner housing 9 shown in Figs. 7A to 7C are arranged.
  • a state, in which the respective members are arranged in the vicinity of tops of the inner and outer housings, and a state, in which the respective members are arranged in the vicinity of bottoms of the housings are not necessarily required to be made the same.
  • Figs. 8A to 8C show a state, in which the degree of freedom in vibration is restricted by the provision of the upper plate member 15 and the lower plate member 16, which comprise a vibration restricting member.
  • Fig. 8A shows a construction, in which an outer housing 11 and an inner housing 9 are connected to each other through vibration absorbing members 10a to 10d and there are not provided any upper plate member 15 and any lower plate member 16 between the housings 11, 9.
  • the vibration absorbing members 10a to 10d and the inner housing 9 connected to the outer housing 11 therethrough are freely displaced in X-axis direction (left and right direction), Y-axis direction (vertical direction), and Z-axis (longitudinal direction), which axes are perpendicular to one another.
  • these members are freely displaced in directions, which twist round the respective axes, that is, directions indicated by arrows a, b, c in Figs. 8A to 8C .
  • a direction of displacement is made only a vertical direction being a direction, in which flexural deformation of the upper plate member 15 and the lower plate member 16 is caused, so that vibrations are restricted only in Y-axis direction.
