Patent number: 6128987Abstract: A hydraulic press has closed loop feedback control on a slide, a slide pad and bolster cylinders. Hydraulic cylinders actuating various components of the press are controlled according to ideal position estimates to produce consistent and precise pressing action. A closed loop control consists of an ideal position/pressure value generator, a position/pressure detector and an arithmetic unit comparing the ideal and actual position/pressure values. Using the ideal and actual comparison result, the arithmetic unit produces a control signal to drive a cylinder to a desired position/pressure. The hydraulic press is capable of performing several operations on a workpiece in one press cycle, an improvement over presses requiring several operation steps or die changes. The bolster cylinders augment clamping force, reduce shock, and improve die alignment to produce better results with less wear on press components.Type: GrantFiled: February 19, 1998Date of Patent: October 10, 2000Assignee: Aida Engineering Co., Ltd.Inventors: Tatsuji Nakagawa, Itaru Fujimura, Hiroshi Hosoya, Junkichi Comikawa, Kazuhiko Fujimoto

Patent number: 5201258Abstract: A station (10) for cutting sheets of wood (13), and in particular for cutting packages of sheets, includes a first device (12) for positioning a package of sheets under a first cutter (15) so as to separate parts of the package sequentially. A further device (14) takes the cut part and sends it to a second cutter (17) for sequentially cutting the part along a second direction so as to obtain another division in subparts sequentially and selectively conveyed outside the station. Electronic controls are used to manage operation of the cutters and the positioning and taking devices for performing the cuts in accordance with a previously set grid of cuts.Type: GrantFiled: February 20, 1992Date of Patent: April 13, 1993Assignee: Angelo Cremona & Figlio S.p.A.Inventor: Lorenzo Cremona

Patent number: 5043907Abstract: A band saw having a controller responsive to sensing signals as to operating parameters of the saw to generate a material distribution profile during a first cut of a piece of bar stock is disclosed. During subsequent cuts, the controller for the band saw operates control circuits for blade cutting force, blade feed rate and blade speed to maintain a desired, usually constant, material cutting rate of the bar stock, notwithstanding changes in bar stock cross section and changes in band saw geometry during the cut. A method is disclosed in which operating parameters are sensed, a distribution profile generated, and the profile employed during subsequent cuts to control the operating parameters for optimum cutting efficiency.Type: GrantFiled: May 11, 1990Date of Patent: August 27, 1991Assignee: Hem, Inc.Inventor: Mark P. Richards

Patent number: 5014583Abstract: A push feed system for feeding articles from one position to another, and particularly for feeding pieces to be cut to a jump saw, includes a computer-controlled drive means having a stepper motor connected to drive a double sided toothed belt in engagement with a toothed rack, whereby operation of the belt causes relative movement between the belt and the rack, and a push bar connected to be driven by the drive means. The double sided toothed belt ensures transmission of a large amount of power without slippage, and the computer is programmed to correct for minor differences between a selected cut length and a measured cut length as might be caused, for example, by the dimension of material removed by the saw. A shock absorber is positioned between the push bar and the drive means to absorb impacts between the push bar and stationary pieces.Type: GrantFiled: August 29, 1989Date of Patent: May 14, 1991Inventors: William J. Webb, Stoddard H. Pyle

Patent number: 4989483Abstract: An apparatus for putting on a thin strip a bar code consisting of a plurality of parallel thin and wide bars of respective thin and wide widths and a plurality of thin and wide spaces separating the bars has a plurality of stations spaced apart along a transport path extending in a transport direction and each having a respective group of tools of the relatively thin width, the tools of each station being immediately juxtaposed with one another in the direction. The strip is stepped in the direction along the path through the stations and only selected ones of the respective tools are selected and moved by actuators down into the strip. A controller is connected to the selector and actuator unit and to the transporter for forming each of the thin bars by pressing into the strip a one of the tools.Type: GrantFiled: February 7, 1990Date of Patent: February 5, 1991Assignee: Lacrouts Cazenava SarlInventor: Joel G.

Patent number: 4977805Abstract: An edging apparatus edges a wood board to achieve a desired rounding effect under a rounding rule of the lumber industry. A positioning apparatus positions and holds two edging saws, and the positions of the saws are initially controlled by an operator who selects initial cut positions. Input data, including board length and thickness parameters and the initial cut positions are generated by input devices and a computer is responsive to the input data for computing the best cut positions of the saws. In making this computation, the computer takes into consideration the rounding rule and, according to predetermined criteria, the computer selects best cut positions that will produce an edged board whose measurement exceeds a whole board foot measurement by a desired fraction of a board foot. Adjustment input may be provided to adjust the size of the desired fraction of the board foot.Type: GrantFiled: June 16, 1987Date of Patent: December 18, 1990Assignee: Corley Manufacturing CompanyInventor: Andrew J. Corley, III

Patent number: 4879934Abstract: A selective wire feed for feeding any one of a plurality of wires which are arranged in pairs, each pair having a first wire and a second wire. Each wire pair has a feeding unit associated therewith which comprises a driven belt and two idler belts. The idler belts are movable between a feeding position and a non-feeding position. A specific wire is fed by moving its associated feeding belt to its feeding position and actuating the driven belt so that the wire is fed by the two belts. A wire guide is provided and has convergent passageways which extend to a wire outlet. A cutter is provided adjacent to the outlet so that a wire which has been fed can be cut. Thereafter, the wire which has been fed can be retracted by reversing the direction of the driven belt.Type: GrantFiled: October 8, 1987Date of Patent: November 14, 1989Assignee: AMP IncorporatedInventors: Daniel T. Adlon, Kenneth F. Folk
