Definitions

  • the present invention relates to an operating assembly for the insertion of connection pins into wood components or the like.
  • the present invention relates to an operating assembly for the insertion of connection pins into wood components or the like of the type comprising a feeding unit to feed a liquid into a housing hole made in a wood component or the like and an insertion unit to insert a connection pin into the housing hole.
  • the operating assembly is used in a machine for machining wooden or similar components comprising a base, a gripping system to receive and hold at least one component and an operating head provided with at least one tool.
  • the gripping system and operating head are mutually mobile to allow the tool to perform machining by chip removal of the components.
  • the gripping system and operating head are mutually mobile to allow the feeding unit to feed the liquid into the housing hole and the insertion unit to insert the connection pin into the same housing hole.
  • the machine When the operating assembly is fixed, the machine has an actuation device to move the gripping system and thus, the component with respect to the operating assembly.
  • the machine When the operating assembly is mobile, the machine has an actuation device to move the operating assembly with respect to the gripping system and thus to the component.
  • the aim of the present invention is to make an operating assembly for the insertion of connection pins into wood components, or the like, which is free of the drawbacks described above and which is easy and economical to implement.
  • reference numeral 1 globally denotes, an operating assembly for the insertion of connection pins 2 into relative housing holes 3 made in components, in the case in point panels 4, of wood or the like.
  • the operating assembly 1 comprises an electro-spindle 5 and equipment 6 fitted on the electro-spindle 5 in a removable manner.
  • the electro-spindle 5 comprises an external tubular casing 7 housing an electric motor known and not illustrated inside it provided with a rotor keyed to a tubular output shaft 8, a free end section of which defines a tool-carrier spindle 9 mounted so as to rotate, with respect to the casing 7, around its own longitudinal axis 10.
  • the spindle 9 protrudes partially from the casing 7 and has a seat 11 (in this case a conical seat) suitable to receive and center a shank 12 of the equipment 6 by means of a positioning pin 12a.
  • a seat 11 in this case a conical seat
  • the electro-spindle 5 further comprises a coupling device 13 comprising, in turn, a gripping member 14, designed to engage the shank 12 of the equipment and an actuator, known and not illustrated, designed to move the gripping member 14 between a locking position ( Figure 1 ) of the equipment 6 on the spindle 9 and a release position (not illustrated).
  • a coupling device 13 comprising, in turn, a gripping member 14, designed to engage the shank 12 of the equipment and an actuator, known and not illustrated, designed to move the gripping member 14 between a locking position ( Figure 1 ) of the equipment 6 on the spindle 9 and a release position (not illustrated).
  • the equipment 6 comprises a frame 15, which is substantially plate-shaped, is provided with a shank 12, and supports two feeding and insertion systems 16 acting in two opposite, insertion directions 17, 18.
  • Each system 16 comprises a feeding unit 19 to feed a liquid into the holes 3 and an insertion unit 20 to insert the connection pins 2 into the same holes 3.
  • the feeding unit 19 comprises an injection nozzle 21 that can be connected to a containment tank (not shown), which houses a glue inside when the pins 2 are free of glue and water when the pins 2 are pre-glued.
  • the insertion unit 20 comprises a storage 22 of the pins 2 made in the frame 15.
  • the storage 22 is in the form of a feed duct 23, which receives the pins 2 from a tubular connection 24 connectable with a feed hopper (not illustrated), and cooperates with a pneumatic feed device (not illustrated) designed to move the pins 2 in succession along said duct 23.
  • the unit 20 further comprises a distribution drawer 25 provided with a transfer duct (not illustrated) made through the drawer 25 in the relative direction 17, 18.
  • the drawer 25 is attached to an output rod 26 of an actuator cylinder 27, and is moved by the cylinder 27 in a direction 28 transverse to the directions 17, 18 between a first operating position, in which the transfer duct (not illustrated) is aligned with the duct 23 in the direction 17, 18 to receive in input a pin 2, and a second operating position, in which the transfer duct (not illustrated) is aligned with a pushing device 29 in the direction 17, 18 to release in output said pin 2.
  • the device 29 is common to the two systems 16, and comprises a tip 30, which extends in the direction 17, 18, and is moved in the directions 17 and 18 by an actuator cylinder 31 fixed to the frame 15 parallel to the direction 17, 18.
  • the tip 30 is moved by the cylinder 31 with a reciprocating rectilinear movement comprising an outward stroke, in which the tip 30 engages the transfer duct (not illustrated) of one of the drawers 25 to push the corresponding pin 2 inside a relative hole 3, and a return stroke, wherein the tip 30 engages the transfer duct (not illustrated) of the other drawer 25 to push the corresponding pin 2 inside a relative hole 3.
  • the coupling between the electro-spindle 5 and the equipment 6 via the coupling device 13 allows use of the equipment 6 in a machine for machining wooden panels 4, or the like, by making use of actuation devices of the electro-spindle 5 already present in the machine.
  • the equipment 6 can be stored in a machine tool-holder magazine and can be mounted on the electro-spindle 5 manually or via an automatic tool change device.
