Patent number: 10792777Abstract: A method and apparatus for changing pallets delivered to a machining center. Different workpieces are connected or attached to different pallets. A first workpiece corresponding to a first pallet is delivered to or near an indexer or indexer assembly and the indexer is moved into an engaged position and performs a work operation on the first workpiece. The indexer is then moved to a disengaged position and the first pallet and the first workpiece are exchanged or switched out with a second pallet having a second workpiece. The indexer is then moved to an engaged position and works the second workpiece and when completed, the indexer moves to the disengaged position and the second workpiece is exchanged or switched out with a third pallet having a third workpiece. The indexer system of this invention can quickly and cost-effectively cycle through different pallets and thus different workpieces.Type: GrantFiled: October 26, 2018Date of Patent: October 6, 2020Assignee: MIDACO CORPORATIONInventors: Michael Paul Cayley, Sr., Malcolm E.

Patent number: 7975998Abstract: A pallet changer and a system and a method for using the same attach, secure and/or connect a part and/or pallet assembly to a receiver assembly for machining the part. A groove and/or a pull post of the pallet assembly is insertable between a first wedge arm and a second wedge arm in an interior of the receiver assembly. Springs within the interior of the receiver assembly exert forces against the first wedge arm and the second wedge arm to maintain the first wedge arm and/or the second wedge arm in a first position within the interior of the receiver assembly. A key and/or a cam moves and/or rotates to move the first wedge arm and/or the second wedge arm from the first position to a second position. A first tapering on the pallet assembly engages and/or corresponds to a second tapering on the first wedge arm and/or the second wedge arm to secure and/or to attach the pallet assembly to the receiver assembly in the second position.Type: GrantFiled: April 3, 2006Date of Patent: July 12, 2011Assignee: Midaco CorporationInventors: Malcolm E.

Patent number: 6308815Abstract: A rotatable pallet changing apparatus, a system and a method are provided in which the rotatable pallet changing system has a rotatable bed having a first pallet and a second pallet side-by-side and set on tracks. A first and a second workpiece may be set upon a first pallet and a second pallet, respectively. As the first pallet with the first workpiece is drawn into a machining center to be worked upon, the second workpiece may be added to the second pallet. When the first workpiece on the first pallet is finished being worked upon, it is withdrawn from the machining center and placed upon the rotatable bed. The rotatable bed then rotates, allowing the second pallet to be fed into the machining center and further allowing the first workpiece to be off-loaded from the first pallet.Type: GrantFiled: October 15, 1999Date of Patent: October 30, 2001Assignee: Midaco CorporationInventor: Malcolm E.

Patent number: 6193048Abstract: An automatic pallet changer system in an automatic machining center has a first track for receiving a first pallet having a first workpiece thereon, and a second track for receiving a second pallet having a second workpiece thereon. The first and second tracks are side-by-side and extend from a region outside the enclosure to a region inside the enclosure adjacent the receiver. A linear drive unit is arranged between the first and second tracks and has a carriage which moves along a longitudinally extending carriage guide. The carriage has a member for engaging with the first or second pallet depending upon whether the linear drive unit is rocked to the left or to the right. A motor is connected to the linear drive unit for causing a movement of the carriage along the carriage guide.
