  • PATENTEDNUV 23 I971 SHEET 1 OF 2 INVEN'IORI Keck PATENTEmmv 23 I97! 3, 22,023
  • This invention relates to the setting up of green molded bricks or similar objects in gapped columns, and particularly to apparatus for setting up such objects of substantially uniform dimensions in aplurality of gapped alignedly juxtaposed columns.
  • Green bricks are normally received from automatic molding machinery in continuous columns. Yet, during subsequent firing in a kiln, the bricks need to be spaced sufficiently to give reasonably uniform access to the heat of the kiln, and settingup devices are employed for converting the continuous columns of molded bricks to juxtaposed gapped columns which may then be transferred to kiln cars without disturbing their spatial relationship.
  • the known setting-up devices are not capable of maintaining the desired alignment of the bricks under unfavorable operating conditions.
  • the shortcomings of the known devices are due, in part, to insufficient control over the movement of individual bricks.
  • Some of the known devices rely on friction for moving the bricks during setting-up, and the results achieved vary with the shape of the bricks or with the position of a brick in a batch.
  • Setting-up devices which rely on friction formoving the bricks are least effective with bricks that are very narrow. Yet, highest numerical capacity is expected from setting-up devices when operating on such bricks.
  • a primary object of the invention is the provision of settingup apparatus for green molded brick which forms precisely aligned, uniformly gapped columns from bricks received in continuous columns without intervention of a human operator.
  • the invention provides a stationary platform formed with a plurality of spacedly juxtaposed slots extending in a common direction.
  • a horizontally extending continuous conveyor is contiguously adjacent the platform in the direction of slot elongation.
  • a first gripper hoist sets the bricks on the platform in continuous columns extending in the direction of the slots.
  • a carriage is mounted under the platform and is equipped with a drive mechanism which causes reciprocating movement of the carriage in the direction of the slots.
  • Pusher arms are movably mounted on the carriage and respectively aligned with the slots.
  • An actuating mechanism responds to the carriage movement while bricks are on the platform for holding the pusher arms in respective first positions during movement of the carriage toward the conveyor. in this position, the pusher arms project from the slots for engagement with the bricks on the platform.
  • the pusher arms are in a second position and withdrawn from the platform.
  • the conveyor may be moved away from the platform by its drive mechanism, both drive mechanisms being operated in timed sequence by a common control device.
  • the gapped columns of bricks formed on the conveyor by suitable operation of the two drive mechanisms are lifted by a second gripper hoist.
  • FIG. 1 shows a setting-up apparatus of the invention in side elevation
  • FIG. 2 illustrates the apparatus of FIG. 1 in fragmentary, front elevational section on the line Il-ll.
  • a travelling gripper hoist 1 known in itself, which transfers a batch of green molded bricks in continuous columns 3 horizontally juxtaposed from a nonillustrated discharge conveyor of an automatic molding machine to a platform 2.
  • the platform essentially consists of steel bars or beams 4 mounted on supporting structure in parallel spaced relationship so as to define slots 5 therebetween.
  • a continuous, horizontal belt conveyor 6 is mounted between an idler pulley 7 and a drive pulley 8 in such a manner that the terminal portion of the platform 2 contiguously adjacent the conveyor 6 is slightly higher than the latter.
  • a second travelling gripper hoist 9 is provided for transferring the suitably arranged bricks from the conveyor 6 to a nonillustrated kiln car for subsequent firing.
  • the green molded bricks are moved from the platform 2 to the conveyor 6 by a transport mechanism 10 which includes two continuous chains 11 attached to a carriage 12.
  • the carriage moves along tracks 13 under the platform 2 on wheels 14 in the direction of elongation of the slots 5.
  • a transverse row of pusher arms 15 is pivotally mounted on the carriage 12, each arm 15 being aligned with a respective slot 5.
  • the arms are biased by nonillustrated springs or counterweights toward engagement with fixed abutrnents (not shown) in the illustrated position in which the enlarged free ends 150 of the arms 15 project upward between the bars 4 from the slots 5.
  • Planar faces 16 of the arms are directed toward the conveyor 6.
  • the cooperating cams and switches control the motor drive for the chains 11 and a nonillustrated variable-speed motor in the drive mechanism for the pulley 8 in such a manner that gaps 22 are formed between the molded bricks 311 on the conveyor 6, and gapped columns 23 are formed, the gaps 22 in each column 23 of bricks being transversely aligned with corresponding gaps in juxtaposed columns 23.
  • the desired configuration of the bricks 3a on the conveyor 6 is brought about as follows:
  • the bricks in the several columns 3 on the platform 2 are transversely aligned in rows while they are moved toward the conveyor 6.
  • the posi tion of the front row of bricks 3' in the batch on the platform 2 is precisely correlated with the position of the carriage 12.
  • one of the cams 20 on the disc 19 operates a switch 21 whereby the conveyor 6 is started at an initial speed which is equal to that of the transport mechanism 10.
  • the conveyor 6 is started at an initial speed which is equal to that of the transport mechanism 10.
  • another cam 20 and switch 21 raises the speed of the conveyor 6 and lowers the speed of the carriage 12.
  • the bricks 3a fully supported by the conveyor 6 are thereby separated from the third row on the platform 2 and a gap 22 is opened. Because of the slight difference in level between the top surfaces of the platform 2 and of the conveyor 6, the bricks 30 do not touch the conveyor until they have been pushed over the edge 2a of the platform over more than half their thickness so that gravity causes them to tilt.
  • the speed of the conveyor 6 is reduced and that of the carriage 12 is increased to a common value, and another cycle is begun. This procedure may be repeated until all bricks of the batch on the platform 2 are transferred to the conveyor, and are ready to be lifted by the travelling gripper hoist 9.
  • the gripper hoist 9 may be controlled by an operator or wired into the control circuits of the switches 21 in an obvious manner, and the same holds for the hoist l. A new batch is transferred to the platform 2 while the carriage 12 reaches the end of its stroke nearest the conveyor 6, and yet another switch is operated.
  • the pusher arms 15 cammingly engage the bricks of the newly transferred batch and are depressed into the slots 5 until they pass under all bricks of the columns 3 respectively deposited over the slots 5. When they clear the last row of bricks, they are returned to the illustrated operative position by their springs or counterweights.
  • the distribution of the individual bricks in the gapped columns 23 and the widths of the gaps 22 may be varied in any desired manner by suitably setting the earns 20 and switches 21 about the circumference of the disc 19. Regardless of specific details of the arrangement, perfect alignment of the bricks in straight columns and rows is readily achieved, and handling of each load prior to and after firing is greatly facilitated thereby.
  • the illustrated and described apparatus requires relatively little power for its operation because the speed changes of the transport mechanism and the conveyor 6 are minor.
  • the bricks, once started, do not stop until they are ready to be transferred to the kiln car.
  • the platform 2 is completely cleared before the next batch is set down, and the entire apparatus is empty of bricks when it is to be shut down at the end of a work period.
  • Apparatus for setting up green molded bricks and like objects of substantially uniform dimensions in a plurality of gapped, juxtaposed columns comprising, in combination:
  • a stationary platform formed with a plurality of spacedly juxtaposed slots extending in a common direction;
  • first gripper means for setting said objects on said platform in continuous columns extending in said direction;
  • first drive means for causing reciprocating movement of said carriage in said direction
  • actuating means responsive to said movement of said carriage while said objects are set on said platfonn for holding said pusher members in respective first positions in which they project from said slots for engagement with said objects when the carriage moves toward said conveyor, and for holding said pusher members in respective second positions and withdrawn from said platform when said carriage moves away from said conveyor;
  • drive control means for operating said first and second drive means in timed sequence and for thereby forming gapped columns of said objects on said conveyor;
  • control means include sensing means for sensing the position of said carriage, and operating means responsive to said position for operating said second drive means.
