(Ci. l98-3 l) 6 Claims.
This invention relates to an accumulating device.
It is an object of this invention to provide means for accumulating containers on a continuously moving conveyor until a predetermined quantity is accumulated.
It is a further object of this invention to provide means for releasing containers so accumw lated.
Still a further object of this invention is to provide a device which will collect a predetermined number of packages or cartons out of a random number to send them to a secondary operation.
It is still a further object of this invention to provide a collecting device wherein the number of packages or containers collected can be readily adjusted.
It is still a further object of this invention to provide means to accumulate a predetermined quantity of containers from a random number along a continuous conveyor, release the containers and return to the operative position to collect a second quantity of cartons or the like.
Other objects and advantages of this invention will be apparent from the following descrip tion.
In the drawings:
Figure 1 is a top plan view of a continuous conveyor embodying this invention.
Figure 2 is a side elevation of the accumulating device.
Figure 3 is an end View taken along line 33 of Figure 2.
Figure 4: is a schematic wiring diagram.
Referring now to the drawings, and particularly Figure 1, a continuous conveyor is illustrated moving from left to right in Figures 1 and 2. The conveyor comprises belts ill and i2, which are looped about pulleys, such as hi and I6, at each extremity of the belts. Each pair of pulleys, such as I4 and it, are mounted on a shaft l8, which is journaled in bearings 2!! and 22, which in turn are suitably mounted on the longitudinal runners 24 and 25 of the conveyor. The runners are supported by legs, such as 28 and 3B, spaced at suitable intervals along the conveyor and strengthened by cross braces 31.
Spaced at suitable intervals along the runners 24 and 26 are a plurality of upright braces 32,
each of which is provided with an aperture adapted to receive a cross bar 35 of one of the rails 36. Set screws 38 are provided to position the cross bars in the upright braces so that the distance between the rails is adjustable to accommodate Various size cartons or containers ill, which rest upon the belts It and i2, and are conveyed by movement of the belts. Said belts are driven by rotation of shaft I8, which has mounted thereon a pair of sprockets 42 and 44. About sprocket d2 the endless drive chain it is looped which is driven by any suitable source of power (not shown). About the sprocket is one end of endless drive chain 48 is looped, the other end being looped about a similiar sprocket formed on a shaft similar to shaft i8, which has mounted thereon pulleys corresponding to pulleys Ill and I6 and about which the unshown ends of belts ill and I2 are looped.
It is desirable to provide supporting plates, such as 52, beneath the belts in and 12, to provide a stable surface upon which the containers are supported. Depending from the spaced supporting plates 52 is a switch 5 The switch comprises a plunger El, which is urged to the closed position against contacts 58 by a spring 60. This switch closes a suitable circuit to energize a solenoid 56. The solenoid 56 is supported by bracket 53, which in turn is supported from a U-shaped bracket Bl, the opposed arms of which are joined to the runners 24 and 28. The solenoid when switch 54 is closed, raises the iron core 62 against the pressure of spring M, which spring is attached at one extremity to the iron core and at the opposite extremity to the bracket 66, which is suitably secured to the bracket 59. Attached to the core 62 is a plate or finger 53, which has pivoted arms mounted at its upper extremity to stop member lil, as best seen in Figure 3. The connection between the stop member l8 and the finger 88 is by means of a hinge iii. A suitable spring i4 is attached at one extremity to the stop 10 and at the other extremity to the adjacent cross brace 31, urging the stop to the upright position. When the solenoid is energized, raising the iron core, finger, and stop to its uppermost position, the upper extremity of the stop projects between the parallel belts It: and I2 and prevents the containers 20 from being carried beyond the stop. When a sufiicient numher of containers 4!! have thus been backed up along the belt, the force of such containers will urge the stop to pivot in a clockwise direction against the pressure of spring 14. The stop 10 carries thereon a breaker 76, which is adapted to strike plunger 51 of switch 54, urging the plunger 57 away from the contacts 58 against the pressure of spring 60, thus opening the switch. When the switch is thus opened, the circuit is broken, the solenoid 56 is de-energized permitting the spring 64' to draw the core, finger, and stop 18 downwardly so that the upper extremity of stop I is drawn below the level of the belts l0 and I2, permitting the containers 4!] thus accumulated to continue to travel along the conveyor. It is readily apparent that the number of the containers thus accumulated prior to the breaking of the switch 54 by the pivoting of the stop can be varied by varying the tension of the spring 14. For this purpose, it is desirable to join the spring 14 to the cross brace 3| by means of an adjustable screw 18. It is desirable to provide means for delaying the closing of the circuit to the solenoid when the stop I0 is lowered, for at this time the spring 14 urges the stop to its upright position and the switch 54 is again closed by the action of spring 60. Depending, of course, upon the pressure of spring 14, it is possible to accumulate a large quantity of containers, so that all of the containers would not be carried beyond the position of the stop by the time switch 54 has closed and the solenoid is thereby energized, raising the stop 10 into the operative position. In thisevent, it is desirable to provide delaying means in the electrical circuit energizing the solenoid.
One means of causing the delay is provided by an overhead switch 80, which is supported from the vertical bracket 82, projecting upwardly from the longitudinal runner 25.
The switch Bl] has an arm 84 pivotally connected at one extremity, as at 86, and projecting substantially horizontally along the path of travel of the containers. This arm 84 carries thereon one contact 88 of the switch. Thus, when a container is held by the stop, the arm 84 is in its lowered position with its extremity 9B projecting beyond the carton 40 and the switch 80 is closed completing the circuit to solenoid 55. When the cartons pass beyond stop 10 they contact extremity 90 raising arm 84 and opening the switch 80, thus opening the circuit to solenoid 55, independent of switch 54. When the cartons have passed extremity 90, the arm 84 ivots downwardly, closing switch 80. The switch 89, when closed, completes the circuit to the solenoid 56, energizing said solenoid and raising the stop H! into the path of the containers. When this overhead switch 80 is utilized to re-energize the solenoid, the circuit containing switch 54 is open until the switch 80 is closed, so that the closing of the switch 54, after the stop 10 has been lowered below the path of the containers, will not energize the solenoid 55.
While what hereinbefore has been described is the preferred embodiment of this invention, it is readily apparent that various alterations and modifications can be resorted to without departing from the scope of this invention, and such alterations and modifications are intended to be included within the following claims.
