DETAILED DESCRIPTION Turning now to the drawings in greater detail, FIG. I shows an infeed conveyor 10 of the continuously operated type, but in the present case fitted with a high-low speed clutch 12 interposed between the drive roll 14 and the motor 16 to operate said conveyor 10 at either of two selected speeds. As shown in FIG. 2 the conveyor 10 is adapted to feed articles, in the form of six pack cartons, continuously in the downstream direction, as indicated generally by the arrow 18, across a deadplate 20 located in the same plane as the upper run of the conveyor 10. The articles being handled in the apparatus shown comprise rectangular cartons C, C each of which has been previously packaged with six generally conventionally shaped bottles or cans as indicated generally at D, D in FIG. 2. Each of these cartons C,C is adapted to be fed by line pressure across the deadplate 20 and into the grid structure to be described.

The grid structure includes a fixed frame having an upstream end plate, or cross member 22, as well as a corresponding cross member 24 at the downstream end. Longitudinally extending support members 26, 28 are connected at either end to these cross members 22 and 24, as best shown in FIG. 2. These longitudinally extending members 26 and 28 are arranged slightly below the level at which the cartons C,C are fed into the grid structure. Two sets of fixed guide rails 30 and 32 are provided to further support the grid su'ucture cross members 22 and 24 in parallel relationship with one another. The lower set of guide rails 30a and 32a are provided immediately below the upper set of guide rails 30 and 32, and these sets of guide rails 30, 30a, 32 and 32a slidably support shifting carriage portions of the grid structure to be described hereinbelow. The upstream cross member 22 of the fixed grid structure includes a cantilevered yoke or frame which carries a line brake means, indicated generally at 40 in FIGS. 1 and 2. The line brake means 40 is adapted to selectively hold back the cartons QC on the infeed conveyor, and more particularly clamps the carton which is located on the deadplate 20, to permit operation of the shifting carriage portions A and B. The line brake means 40 is of conventional construction, and comprises a pair of pneumatic actuators, indicated generally at 42, 42. A fixed part of each actuator 42 is mounted to the cantilevered frame 44 and a movableportion 46 of each actuator carries an abrasive disc for frictionally engaging the carton C on the deadplate to clamp said carton therebetween.

As mentioned above with reference to FIG. 2, two side-byside lanes of cartons C,C are adapted to be fed into the grid structure, and it is a feature of the grid structure that each of the carriage portions A,B is slidably mounted on the rods 30, 30a and 32, 32a to define longitudinally extending lanes for receiving each of these lines of cartons C, C. A fixed plate 48 is provided between the line brakes associated with deadplate 20, and lane defining plates are provided in each of the shifting carriage portions, as indicated generally at 50 and 52, in longitudinal alignment with the fixed plate 48 for achieving this lane defining function in the grid structure. To further define the lanes in the grid structure a pair of bottom doors 54 and 56 are also provided in each of the shifting carriage portions of the grid structure so that the cartons C,C are fed across these doors and between these lane defining plates 50 and 52in response to the line pressure of the cartons on the infeed conveyor 10. Finally, and still with reference to the lane defining portion of the grid structure, leftand right-hand outer extremities of each of the lanes are defined by vertically extending side plates 58, 59 and 60, 62.

The bottom doors 56 and 56 of the upstream or first carriage portion A hingedly connected to rock shafts 64 and 66, which rock shafts are in turn rotatably supported at either end in bearing blocks 68, 68 and 70, 70, respectively. These bearing blocks 68 and 70 are in turn mounted to the side walls 58 and 59, respectively. The center plate 50, which is located between the two side-by-side lanes in the bridge structure, is hung from a cross member 70 provided for this purpose at the upper ends of each of the bearing blocks 68 and 68. Each bearing block 68, 68 defines a pair of slide bushings for slidably receiving the fixed guide rods 30 and 32 mentioned previously in the fixed grid structure. Still with reference to the upstream carriage portion A of the grid structure, a second cross member 71, located in spaced relationship to the cross member 70, supports a pair of small actuators slaved to the line brake actuators 42, 42 for operation therewith. The movable portions of these actuators carry pucks 72, 72 for en-- gaging the two cartons C,C located immediately therebeneath the pucks 72, 72 so as to hold these cartons in contact with the bottom doors 54, 54 mentioned previously. As best shown in FIG. 2, the first carriage portion A defined by the structure described hereinabove can be seen to be slidably supported on the fixed guide rods 30, 30a and 32, 324 by means of the four slide bearings indicated generally at 67, 67. Each of the lower fixed guide rods 30a, 32a includes a fixed flange 73 which engages one end of a coil compression spring 74 acting between this flange and the rear face of the slide block 67 associated with the upstream end of the firs carriage portion A. It will be apparent that these springs 74, 74 serve to urge the first carriage portion A upstream against a limit stop defined by the pair of snubbers 75, 75 mounted for this purpose in the fixed cross member 22 of the fixed grid structure. These snubbers are of conventional construction, and can be adjusted to vary the limit of travel of the carriage portion in the upstream direction.

The second lane defining sliding carriage portion B of the grid structure is similar to the first but not connected thereto except through a lost motion mechanism, indicated generally at 76 to be described in greater detail hereinbelow. As shown in FIGS. I and 2, the second carriage portion B also includes lane defining side plates 78 and 79, together with a central plate 80, and also includes bottom doors 56, 56 as mentioned hereinabove, each of which is rotatably supported by means of rock shafis 84, 84 located in axial alignment with respect to the rock shafts 64, 64 in the first carriage portion A. The rock shaft 84 is connected to therock shaft 64 by means of a splined collar 82. Each of these rock shafis 84, 84 is rotatably supported in bearing blocks 87, 87 similar to the bearing blocks 68, 68 described above, and each of these bearing blocks 87, 87 includes an upstanding portion which permits the second carriage portion B to be slidably received on the fixed guide rods 30, 30a and 32, 32a in the same manner as the first carriage portion A described hereinabove. The upstream cross member 85 associated with the second carriage portion B is similar to the cross members 70 and 71 described above, and like thecross member 71, carries a pair of small slaved pneumatic actuators which operate in conjunction with the line brake 42 so as to clamp a carton C between their associated pucks 86, 86 and the doors 56, 56 associated with the second carriage portion 8.

Still with reference to the second carriage portion B associated with the downstream group of cartons, the downstream end of said second carriage portion B includes an end wall 90 against which the cartons can abut as they are fed into the grid structure by the line pressure of the cartons on the infeed conveyor 10. An actuator 94 has a fixed part carried by the downstream cross member 24 of the fixed grid structure and a movable part connected to the end wall 90. As

so constructed andarranged, extension of the movable portion of this actuator 94 causes the second carriage portion to move in the upstream direction so as to contact the first grid defining-portions and to move it into contact with the fixed stop defined by the snubbers 75, 75 so as to permit loading of the grid structure by a predetermined number of articles, in this case by eight cartons arranged in two side-by-side lines.

Means is provided in the end wall 90 of the second carriage for detecting the presence of containers C, C in the configuration mentioned above. Preferably, said detecting means comprises the lane detection switches lLS and 2LS mounted on the end-wall 90 and having sensing arms 96 and 98 adapted to close the switches lLS and 2LS whenever the swinging panels or doors 95 and 97, associated with the two lanes in the grid structure, are moved into their closed positions by the cartons. Means is provided for normally biasing these doors 95 and 97 to an open condition so that eachof them is adapted to be closed in response to the pressure of articles or cartons fed into the grid structure.

Turning now to FIG. 3, it will be seen that a pair of actuators 100 and 102 are pivotally mounted on brackets 104 and 106,

respectively, provided for this purpose on the downstream cross arm 99 of the second carriage portion B. These actuators 100 and 102 include depending movable portions 108 and 110, respectively, each of which is connected to one arm of two bell cranks 112 and 114, respectively. These bell cranks 1 12 and 1 14 are clamped to the rock shafts 84, 84 associated with the bottom doors 56, 56 and are adapted to open these doors in response to pressurizing of these actuators 100 and 102. An equalizer, or crossover am 115, is provided between secondary crank arms of the bell cranks 112 and 114 so as to assure that both of these doors 56, 56 operate in synchronism with one another.

The grid retract cylinder 94 is adapted to be moved from its extended position shown in FIGS. 1 and 2 in response to energizing of a solenoid, indicated generally at solenoid B in FIG. 9, so as to pull the second carriage portion B from the position shown to a downstream position, best shown schematically in FIG. 6, and a lost motion mechanism, indicated schematically in FIGS. 4, 5 and 6 at 120, is provided for moving the first carriage portion A a slightly smaller distance in response to the travel of the grid retract cylinder 94. This lost motion mechanism comprises a pair of rods 76, 76 rigidly attached to the second carriage B and'located on either side of the grid structure generally between the fixed guide rods 30, 30a and 32, 32a. Each rod 76 is clamped to the second carriage portion 8 by nut means 119, 119 and the grid retract cylinder 94 is retracted in response to energizing of solenoid B as shown in FIG. 9, so as to pull the second carriage portion B from the normal position illustrated in FIG. 5 to a downstream position wherein it is spaced from the first carriage A as best shown in FIG. 6. The first carriage portion is also pulled downstream, but only through a lesser displacement, as a result of the lost motion mechanism 120. Thus, in FIG. 6 the first carriage portion is spaced downstream from the carton C held by the line brake 40. Preferably, the upstream ends 119, 119 of the rods 76, 76 are threaded to receive pre-positioned lock nuts 119, 119 which are adapted to contact the upstream face of the slide bearing blocks 67, 67 on the first carriage portion.

Thus, in response to a predetermined travel of the actuator 94 and as limited by snubbers a, 75a, the first carriage portion A will have shifted through its predetermined displacement and the second carriage portion will have shifted through a second predetermined displacement slightly greater than that of the first. As indicated schematically in FIGS. 5 and 6, the line brake 40 together with the carton clamping devices associated with each of the carriage potions, 75 and 85, are adapted to clamp the associated cartons C, C to the bottom doors, 54 and 56, respectively. This carton clamping function is accomplished upon the closing of the limit switches lLS and 2LS which comprise the lane detection device for indicating when the cartons are in position so as to be'ready for separation within the grid structure. From FIG. 5, it will be readily apparent that the line brake 40 is adapted to clamp only one carton C against the deadplate 20, which deadplate comprises a fixed portion of the grid structure. The carton clamping devices 72, 72 on the carriage portion A are adapted to clamp four cartons C,C at substantially the same time that line brake 40 is energized, and in response to energizing solenoid A. The downstream clamping devices 86, 86 associated with the second carriage portion B are adapted to clamp two cartons C, C against the bottom doors 56, 56. The cartons downstream of the devices 86, 86 are securely held between the clamped cartons and the end wall 90 of the second carriage portion B. After the cartons are so clamped and following a predetermined time delay introduced by relay TDR-l, the grid retract cylinder 94 is energized, pulling the first and second carriage portions A and B through their predetermined linear displacements so as to provide a space between the cartons held in said carriage portions and between the fixed cartons associated with the line brake 40 and the upstream-most cartons held in the first carriage portion A. V I

Means is provided for raising a pair of packing cases C and D in position on a lift table 130 so as to be readily packed when the doors 54, 54 and 56, 56 are opened so as to drop the cartons C,C. The mechanism for so raising the packing cases C and D comprises a conventional component of the present combination and need not be described in detail herein. However, it should be noted that when the lift table 130 has raised the cartons C and D to be filled in position for accepting these cartons, a limit switch 5LS is closed, and as a result of the circuitry shown in FIG. 9, a trap door solenoid C is energized, providing air under pressure to the actuators and 102 associated with opening the doors from their closed positions shown in FIG. 7 to their open positions best shown in FIG. 8. A time delay relay TDR-2 is also energized simultaneously with solenoid C, and after the expiration of a predetermined time delay, the contacts TDR-l associated with the relay TDR2 will be closed, energizing control relay CR2. This relay CR2 controls the de-energizing of solenoid C through normally closed contacts CR, and returns the trap doors to the closed position following this delay. With further reference to control relay CR2, a set of normally open contacts 2CR associated therewith are adapted to effect retracting of the grid to its normal position for receiving a second group of articles.

This is done through a third control relay CR3 which has as-- sociated therewith normally closed contacts for de-energizing solenoid B.

Turning now to a more detailed specific description of the control circuitry shown in FIG. 9, the normally open lane detection switches lLS and 2LS are adapted to be closed when the grid structure has received a full complement of cartons C,C to be loaded. Upon closing of these switches, a first control relay CR1 is energized, closing contacts lCR and energizing time delay relay TDR-l. At the same time, solenoid A is energized, setting the brakes 42 associated with the deadplate 20, as well as the clamping devices associated with the first and second carriage portions A and B. Since the cartons in these carriage portions will be dropped from the grid structure and the switches lLS and 2L8 will reopen long before a second charge of articles is fed into the grid, means is provided for retaining the brakes and clamping devices in their clamped condition, and said means comprises a limit switch 3LS which is normally closed and which is only opened when the grid retract cylinder 94 has again returned the carriage portions to their initial position for accepting a second charge of articles. FIGS. 5 and 6 show the cam means 140 for closing switch 3L8. The time delay relay TDR-l has contacts which when timed out will energize solenoid B for retracting the grid retract cylinder 94, and thereby moving the carriage portions A and B from their FIG. 5 to their FIG. 6 positions. Having reached the position shown in FIG. 6, carriage portion B will close limit switch 4L8 as a result of cam means 150. Limit switch SLS will be closed if a pair of packing cases C and D have been raised into position on the lift table 130, and solenoid C will then be energized causing the doors to be opened and allowing the cartons in the first and second carriage portions A and B to drop downwardly into the awaiting packing cases C and D. These doors 54 and 56 are reset upon the expiration of a predetermined time delay through the contact ZTDR which will be timed out when relay TDR-2 is energized. Time delay relay TDR-2 is energized simultaneously with the energizing of solenoid C associated with opening the doors themselves. Its contacts ZTDR control relay 2CR which in turn controls solenoid C. A limit switch 7LS associated with these doors as shown in FIGS. 5 and 6 will be closed when the doors return to their closed position, energizing relay CR3, and causing the control solenoid B for the grid retract cylinder to allow the latter to return to its normal position.

Finally, and still with reference to FIG. 9, means is provided for normally operating the infeed conveyor 10 at a predetermined low speed except when it is necessary to speed up the conveyor so as to advance the cartons C,C into the grid structure. In order to accomplish this function, a photocell and light source combination is provided, as indicated generally at 140 and 142, respectively. Whenever the photocell 140 does not detect a light from the light source 142, a solenoid E will be energized, causing clutch 12 to remain in position for low speed operation. On the other hand, high speed operation is is achieved whenever the opposite situation obtains. In this manner the infeed conveyor 10 is sped up whenever cartons are dropped into the awaited packing cases C and D and remains at high speed operation until a charge of cartons C,C is fed into the grid structure so that a carton blanks out of the photocell and the light path thereto, namely just prior to filling of the grid structure with such a charge of cartons.
