Definitions

  • This invention relates to paper and pulp machinery and more particularly to apparatus for loading logs into a magazine for pulp grinders.
  • cut logs are manually loaded into magazines for continuous pulp grinders by operators stationed on the charging floor.
  • the operators divert 'any oversized cut logs back to the woodyard and guide the other cut logs into the magazine parallel to the axis of the grinding stone.
  • the charging floor is usually cluttered with large piles of incoming cut logs and diverted cut logs.
  • the atmosphere is moist and generally foggy due to the frozen, icy condition of the cut logs being processed.
  • the slippery floor and unstable cut log piles create an accident hazard.
  • the cost of this manual labor is high, averaging six men per day for each pair of magazines being loaded.
  • This appaartus comprises a conveyor means for transporting cut logs to the grinder magazine, and a drive means for operating the conveyor means.
  • a gate means is provided intermediate the conveyor means and the magazine, and is movable between a position wherein cut logs are permitted to pass from the conveyor means into the magazine and a position wherein cut logs are prevented from passing from the conveyor means into the magazine.
  • a means is provided for detecting when the magazine is filled with cut logs; and 'a control means is connected to the gate means and the detecting means to be responsive to the detecting means to position the gate means in said position wherein cut logs are prevented from passing from the conveyor means into the magazine when the latter is filled with cut logs.
  • a means is provided for aligning cut logs passing from the conveyor means into the magazine after the cut logs have passed from the conveyor means.
  • FIGS. 1, 1A are continuous plan views of the improved apparatus of the present invention.
  • FIGS. 2, 2A are continuous side elevational views of the apparatus shown in FIG. 1;
  • FIG. 3 is a fragmentary vertical sectional view of the gate means, guide means and associated top of the first magazine shown in FIGS. 1, 2;
  • FIG. 4 is a schematic electrical diagram of the control means for the apparatus of FIGS. 1 and 2;
  • FIG. 5 is a fragmentary detail view of the photocell and lamp
  • FIG. 6 is a view similar to FIG. 5 showing an infra red detecting system.
  • FIG. 7 is a fragmentary side elevational view of an alternative gate locking means.
  • FIG. 8 is a view similar to FIG. 7 of an electric hydraulic gate locking system.
  • a feed means for feeding cut logs 10 to the apparatus of the present invention is indicated generally by the reference numeral 11.
  • This feed means 11 (FIGS. 1, 1A, 2, 2A) comprises a cable conveyor 12, driven by a motor 14, and a log chute 16.
  • the cut logs 10 are fed by the log chute 16 to a conveyor means such as the chain conveyor 18A of the chain conveyors 18A, 18B, 18C, 18D which successively feed the cut logs 10 to magazines 20A, 20B, 20C of pulp grinders (not shown) as hereinafter explained.
  • the chain conveyors 18A, 13B, 18C, 18D are each mounted upon a pair of sprockets 22A, 22B, 22C, 22D which are carried by rotatable shafts 24A, 24B, 24C, 24D, respectively.
  • One of the shafts 24A, 24B, 24C, MD for each of the chain conveyors 18A, 18B, 18C, 18D is rotatably driven by a motor 28A, 28B, 23C, 28D through a gear reduction drive 26A, 26B, 26C, 26D, respectively.
  • Carrier means, such as the lugs 30A, 30B, 30C, 30D are provided, respectively, upon the chain conveyors 18A, 18B, 18C, 181) for engaging the cut logs 10 and maintaining the latter in aligned relationship on the chain conveyors 18A, 18B, 18C, 18D.
  • a cut log 10 slides onto the chain conveyor 18A (FIGS, 1, 2), its forward end engages aligning means, such as the inclined guide 32, which aligns the forward ends of the cut logs 10 on the chain conveyor 18A.
  • aligning means such as the inclined guide 32
  • the aligned cut logs 10 then pass a trimming means, such as the saw 34, which cuts the rearward ends of any oversized cut logs 10 and, thus, dictates the maximum length of the cut logs 10 fed to the magazines 20A, 20B, 200.
  • the photocells 46A, 46B, 46C are connected to relays 48A, 48B, 480, respectively, to energize the latter upon the blocking of light from their respective lamps 45A, 45B, 45C.
  • the relays 48A, 43B, 48C are, respectively, connected to normally open contacts 50A, 59B, 50C to close the latter when energized by the photocells 46A, 46B, 46C.
  • the contacts 56A, StBB, StlC are adapted to energize gate closing means, such as the magnets 52A, 52B, 520, respectively, when closed. This energization of the magnets 52A, 52B, 52C serves to actuate the counterweights 49A, 40B, 40C to move the gates 36A, 36B, 36C to their closed positions and maintain them in such closed positions.
  • the normally open contacts 56A, 56B, 56C when closed, connect the electrical circuits of the photocells and the control circuit for the motors 14, 28A, 28B, 28C, 28D, in series.
  • the contacts 56A, 56B, 56C are closed by relays 54A, 54B, 54C, respectively, which are automatically energized upon the closing of the contacts 59A, StlB, 50C.
  • the motor control circuit includes a rectifier 61, :a relay 58 energized by the closing of all of the contacts SA, 56B, 56C, and a normally closed contact 60 adapted to be opened by the relay 58 when the latter is energized.
  • the contact 68 as shown in FIG.
  • relays 54B and 54A have been previously closed by the photocells 46B and 46A, respectively, the normally open cont-acts 56B and 56A (in series with now closed contact 56C) are also closed.
  • relay b is energized resulting in opening of circuit interrupting means, such as normally closed contact 60 (FIGS. 1 and 4), in the motor circuit and de-energization of motors 14, 28A, 28B, 28C.
  • circuit interrupting means such as normally closed contact 60 (FIGS. 1 and 4
  • the gate locking means may comprise (FIG. '7) a solenoid 64 for operating a lock bolt 66 or, as shown in FIG. 8, an air cylinder 68 connected at 70 to gate 3(A and operated by a valve 72 in turn operated by solenoid 74.
  • An apparatus for automatically loading cut logs into a magazine comprising:
  • conveyor means for transporting cut logs to said magazine
  • gate means intermediate said conveyor means and said magazine and movable between a position wherein cut logs are permitted to pass from said conveyor means into said magazine and a position wherein cut logs are prevented from passing from said conveyor means into said magazine;
  • control means connected to said gate means and said detecting means to be responsive to said detecting means to position said gate means in said position wherein cut logs are prevented from passing from said conveyor means into said magazine when said magazine is filled with logs;
  • said aligning means comprises a member having walls diverging from said conveyor means.
  • said aligning means comprises a yieldable member engageable by cut logs passing into said magazine from said conveyor means.
  • said aligning means also comprises a member having walls diverging from said conveyor means, and said resilient member guides cut logs to said member having said diverging walls.
