Our invention relates to machines for assembling partition strips of cardboard, paper or other material, such as are commonly used to provide individual cells or compartments in cartons and other containers.
The invention in the form herein illustrated, is embodied in a machine of the type in which a piston motor operates to assemble or drive the cross strips in succession into assembled relation with a group of longitudinal strips. A machine of this type is disclosed in U. S. Patent to McLaughlin et al. No. 2,353,842, dated July 18, 1944, for Machines for assembling partitions.
In the machine disclosed in said patent, the operation of the piston motor which assembles the partition strips, is controlled by the strips themselves and particularly by the slots in the 7 Claims. (01. 9337) strips which control the operation of trip valve mechanism in the air control lines of the assembly motor.
An object of the present invention is to provide a simplified and improved means for controlling the operation of the strip assembling motor.
A further object of the invention is to provide a novel mechanism operable independently of the partition strips for eirecting and controlling the successive operations of the strip assembling motor. The invention provides motor controlling air valve mechanism adapted for use in assembling operations in which the partition strips themselves are not adapted for operating the motor control means.
Other objects of the invention will appear hereinafter.
Referring to the accompanying drawings:
Fig. l is a side elevation of the machine.
Fig. 2 is a diagrammatic view, with parts shown in section, of the air system including the airoperated piston motor for assembling the partition strips and the valve mechanism controlling the operations of the motor.
Fig. 3 is a fragmentary view in elevation on a comparatively large scale, of parts shown in Fig. 1, particularly the trip valve mechanism.
Fig. 4 is a plan view of the mechanism shown in Fig. 3.
Fig. 5 is a. sectional elevation at the line 5-5 on Fig. 3.
Fig. 6 is a sectional plan of an auxiliary valve mechanism for preventing the operation of the motor while there are no partition strips passing through the assembly .zone.
Referring to Fig. l, the operating parts, which are mounted on a framework l0, include an electrio motor H which operates continuously throughpspeed reduction gearing including belts I2 and Hi to drive an endless belt conveyor M. The conveyor carries longitudinal partition strips 15 forwardly in a horizontal direction to and through an assembly zone in which they are assembled with cross partition strips l6. Cross bars ['1 are attached to the conveyor I4 at intervals therealong for engaging the strips l5 and holding them properly spaced lengthwise on the conveyor. Stationary guide bars I8 extending lengthwise of the conveyor, serve to support the strips I5 in upright position and suitably spaced laterally. The strips I5 are provided with vertical slots 20 to receive the cross partition strips 16, the lower ends 2| of the slots serving as stops for-the cross partitions which are likewise provided with corresponding slots to receive the lower halves of the longitudinal strips.
The stack of cross strips H5 is supported on an inclined frame member 22 and fed forward by a pusher bar 23 which is slidably mounted on the frame member 22. A weight 24 is connected through a cord 25 and system of pulleys to the bar 23 for applying a yielding pressure of the bar against the stack of strips IS. The cross partition strips are assembled with the longitudinal strips by a piston motor 26. The parts thus far described are the same as illustrated and described in the patent above mentioned to which reference may be had for a more complete disclosure of the general construction and operation of the machine.
Referring now to Fig. 2, the piston motor 26 is operated by air under pressure or other fluid. The air control system includes a main air supply pipe 21 which supplies air under pressure through a valve 28 and filter 29 to an air pressure tank 30. A pressure line 3| extends from the tank to a master control valve 32 which controls the opera- .tion of the motor 26. This valve includes a stem 33 movable lengthwise in the valve casing 34.
The pressure line 3| is connected to the valve at a central port 35. Pipes 36 and 31 extend from the valve 32 to the upper and lower ends respectively, of the motor cylinder. The valve stem 33 is operated by pufis of air which are supplied alternately through the opposite ends of the valve cylinder.
Live air is supplied to the left-hand end of the valve cylinder through an auxiliary pipe line including a pipe 33 extending from the pressure line 3| to an auxiliary control valve 39, a pipe 40 extending from valve 39 to a trip valve 4|,
and a pipe 42 extending from the trip valve to the motor valve 32. The valves 39 and 4! are thus connected in series and when open, as hereinafter described, admit pressure for throwing the Valve stem 33 to the right and thereby admitting air under pressure to the upper end of the motor cylinder. The master valve stem 33 is moved in the opposite direction when air pressure is supplied through a branch pipe line 43 in which is included a poppet valve 44, operated as hereinafter described.
The trip valve 4| includes a valve casing 45 in which is a valve disk 46 having a stem 41 projecting upwardly through the casing. The valve is normally held up in its closed position by a compression spring 48. The valve casing 45 has a stationary mounting on the machine frame.
The trip valve 4| is automatically operated periodically by the flight bars I! on the continuously traveling belt conveyor, through mechanism which will now be described. Such mechanism includes a rock shaft 50 which extends horizontally in the direction of travel of the conveyor, the rock shaft being journalled in arms 5| and 52 at the ends of a bar 53 parallel with the rock shaft. The bar 53 is slidably mounted for adjustment lengthwise along a longitudinal bar 54 of the machine frame. The rock shaft 50 is adjustable lengthwise by means of an adjusting rod 56 having a screw-threaded connection with the arm 5|. The adjusting rod is journalled in an arm 51 attached to the machine frame. Clamping screws 58 extending through elongated slots 59, serve to clamp the bar 53 in its adjusted position.
A finger bar 60 parallel with the rock shaft 50 is connected to the latter by rock arms 6|, said rock arms having split ends to receive the rock shaft and being clamped in position by screws 62. A series of vertically disposed trip fingers 63 are mounted on the finger bar 68 and are individually adjustable lengthwise of the bar and clamped in position thereon by screws 64. The trip fingers are spaced to correspond with the spacing of the slots 20 in the longitudinal partition strips 1 I 5. Each trip finger carries a contact roll 65 adapted to contact any suitable finger-operating devices connected to travel with the conveyor and spaced lengthwise thereof to correspond with the spacing of the flight bars ll. As shown, the flight bars themselves or end extensions 11' thereof, serve as means for operating the trip fingers, the latter being positioned over the conveyor in the path of the flights I! so that each flight as it advances, lifts the trip fingers 63 in succession and thereby rocks the shaft 50. This rocking movement of the shaft operates through a tappet 66 secured to the shaft, to lower the trip valve 46 to open position.
The auxiliary valve 39 (Figs. 2 and 6) is mounted in a valve block 61 bolted to a plate 68, the latter being attached by bolts 69 to one of the spacing bars I8. The inner end of the block 61 is recessed to receive a dog 10 mounted therein by a pivot H. A coil spring 12 held under compression beneath the valve 39 operates to hold the valve closed except when a partition strip i5 is in position to press the dog l inwardly and hold the valve open. The guide strips l8 are arranged in pairs for guiding the longitudinal partition strips l as they advance through the assembly Zone. One of the strips l8 of each pair has a leaf spring 13 attached thereto and bearing against the advancing partition strip. One of said springs is at a point directly opposite the 4 dog Ill and applies pressure through the partition strip and the dog to hold the valve open. When the strip I5 has passed beyond the dog 10, the valve 39 is closed by its spring, thereby closing the air pressure line leading to the motor control valve. When the valve 39 closes, the pressure in the pipe line 40, 42 is dissipated through a vent 14 (Fig. 6)
The motor 25 comprises a piston 15 and piston rod 76. A pusher plate 17, which functions as a partition strip assembling plate, is attached to the piston rod and operates as the piston descends to slice a cross partition strip from the stack and drive it down into assembled relation with the group of longitudinal strips at the assembly station. As the piston nears its lowered position, a cam 18 on the pusher plate 11 engages the stem of the tappet valve 44, opens the valve, and admits air under pressure to the right-hand end of the master valve 32, thereby moving the valve stem to the left and reversing the motor so that the pusher plate is drawn upwardly.
The operation may be summarized as follows:
Groups of longitudinal partition strips l5 are placed on the belt conveyor and positioned thereon with the rear edges of the strips bearing against a flight bar IT. As the group of strips advances to the assembling zone, one said strip passes between the dog if! (Fig. 6) and the adjoining spring 13, causing the dog to open the valve 39. This permits air pressure to be supplied to the trip valve 4! which at this time is held closed by its spring. When the group of strips has about reached the position beneath the pusher plate H for receiving the first cross strip [6, the flight bar ll engages the first trip finger 63 and rocks the shaft 553. This causes the tappet 66 to open the trip valve 4!, thereby supplying air pressure to the left end of the master valve 32, thus moving the valve stem to the right.
The parts are now in the position shown in Fig. 2 with the upper end of the motor cylinder connected to the pressure line. The piston therefore moves downward and causes the pusher plate H to strip the foremost cross partition l6 from the stack and drive it down into assembled position. The cam H! on the pusher bar opens the valve 44 as the motor is completing its down stroke so that the master control valve is reversed. This operation of the motor is repeated as each of the trip fingers 63 is engaged by the bar ll. The number of the trip fingers and their spacing are adjusted to correspond with the number and spacing of the slots 26 in partition strips so that the down strokes of the strip assembly plate H are timed to drive each cross strip into place as it is brought into register with a row of slots 20.
Modifications may be resorted to within the spirit and scope of our invention.
