20 Claims.

This invention relates to apparatus for acting on a mass of articles adherent to one another to separate the articles and deliver them one at a time, so that they can be counted. More particularly, the invention is concerned with novel apparatus of the type described, which is especially adapted for handling soiled textile articles, such as industrial wiping cloths or towels, napkins, diapers, etc., which are supplied to users by service companies and must be disentangled and counted prior to laundering. The new machine performs the functions described at a rapid rate and with a high degree of accuracy, and, in its operation, it requires little attention and few periodic adjustments.

At the present time, various users in quantity of towels and like articles subscribe to services, which deliver a supply of clean towels at intervals and pick up the soiled towels to be laundered for further use. Such soiled towels are commonly returned in large drums or in bundles tied together by a towel or by cord and, as received at the laundry, the towels are usually tangled together in masses and are frequently adherent to one another because of being damp or sticky because of the dirt thereon. Before the soiled towels are laundered, it is important that they be counted, so that the towel service may charge the user with any towels not returned.

The present invention is directed to the provision of a machine, which receives a charge of articles, such as soiled towels tangled together, separates the articles, and delivers them one by one, so that they can be counted. The new machine includes a receptacle for receiving the charge and a conveyor for engaging the charge, removing articles therefrom, and delivering them into a second receptacle. From the second receptacle, the articles are removed by a conveyor having elements, such as hooks, which engage the articles until they have reached a selected point on the conveyor and then release them. At the point referred to, the articles are picked up by elements, such as hooks, on a delivery member and are conveyed past a counting device. The articles being carried by the delivery member to the device are acted on by a beater, which removes from the member any article not rmly held by an element on the member, the articles so removed being returned to the second receptacle. In the machine, the tangled articles are efficiently separated without damage thereto and the chance of more than one article being delivered at a time to the counting device is so small that the machine operates with a high degree of accuracy inthe count.

For a better understanding of the invention. reference may be made to the accompanying drawings, which show one embodiment of the invention in the form of a machine for operation on industrial wiping cloths of such sizes as 18" x 18, 18" x 30", and 18 x 36". In the drawings,

The machine illustrated in the drawings is constructed to operate on a charge of soiled towels, which adhere to one another, and disentangles and separates the towels, so that they can be delivered one by one and counted as they are delivered. The machine includes a frame 2U made up of suitable side and end members and, at one end, the frame carries plates 2l which form opposite side walls of a receptacle for the soiled towels. One end of the receptacle is closed by a gate 22, which is attached by bars 22a to a carriage made up of a cross-bar 23 and end members Z4 provided with wheels 25 running on rails 26. The rails are connected by cross-bars 21 to form a main carriage provided with wheels 28 running on rails 29 attached to cross-bars 3|] of the frame structure. A driven crank shaft 3|, mounted in bearings to extend across the frame. is connected by

linkage

32, 33 to the adjacent cross-bar 21 of the main carriage. As the shaft is driven, the main carriage is reciprocated and carries the gate carriage with it.

A worm gear 34 is mounted on a vertical shaft freely rotatable in a bearing in the cross-bar 23 of the gate carriage and the gear meshes with worm screws 3'5, 36 extending between the opposite cross-bars 2l of the main carriage. Screw 35 is rotatable by a motor 37 connected to the screw by a chain 38. Screw 36 carries a bevel gear 39 (Fig. 12) near one end and the gear meshes with a similar gear 4E] on a stud shaft 4|, which carries the locking element of a directional clutch 42. The oating element of the clutch is secured to a gear 4t, which meshes with a rack 44 secured to a cross-bar 3U of the framework and to a rail 29. With this arrangement, when the main carriage moves in one direction, gear 43 rolls on rack 42 and rotates the floating element of clutch 42 without turning stub shaft 4|. When the main carriage moves in the opposite direction, the elements of clutch 42 engage, so that the rolling of gear 43 on rack 44 causes rotation of stub shaft 4I and of screw 3S. Rotation of screw 3G drives worm gear 34 and causes it to roll on thepstationary screw 35, so that the gate carriage is advanced forwardly a short distance on the main carriage, each time the main carriage is recip-rocated.

A horizontal transverse shaft 45 mounted in brackets attached to vertical members of the frame carries a drum 4t, which serves as a conveyor to raise articles from the receptacle, and the curved surface of the drum lies opposite the gate 22 and forms the central part of the front wall of the receptacle. The face of the drum is narrower than the distance between the side plates 2| and the space between the ends of the drum and the side plates is closed by curved plates 41 lying ush with the surface of the drum at the rear thereof and attached to plates Sil. The lower ends of plates 2| are bent inwardly and a plate 41a lies between the inturned portions of the plates and forms the bottom of the receptacle. The plate is slotted for the passage of the connections between the gate and the carn riage. At the top of the drum, plates 43 are mounted on the frame on opposite sides of the drum and extend outwardly and upwardly from the ends of the drum at the upper part thereof.

A plurality of shafts 49 are mounted in bearing blocks U attached to the inner faces of the ends of the drum near its periphery and each shaft carries a plurality of hooks 5|, which are projected through openings in the surface of the drum and withdrawn into the interior of the drum, as the shaft is rocked. Each shaft has an arm 52 attachedby a connecting rod 53 to a hub 54 mounted on bearings 5 encircling an eccentric 56 on shaft 45. All the connecting rods but one are pivotally attached to hub 54 and their associated arms 52. The connecting rod 53a. is rigidly attached to the hub and acts as a master connecting rod to cause the hub to rotate with the drum. The eccentric is so mounted on shaft 45 that, as the drum rotates counterclockwise, the shafts 49 are so rocked that the hooks are fully projected as they enter the receptacle and fully retracted into the drum 180 later.

Beyond the drum is mounted a second receptacle formed in part by a sheet metal chute 57 attached to vertical members of the frame at opposite sides thereof. The top of the chute lies close to the surface of the drum and a featheredged leather scraper 58 (Fig. 2) is mounted within the chute and lies with its edge against the surface of the drum.

A conveyor in the form of a double chain 59 is trained about pairs of sprocket wheels 60, 6|, and G2 on transverse shafts mounted for rotation in bearings on the framework, and the chain has a vertical stretch rising through the second receptacle. At intervals, the aligned links of the two chains are connected by a bolt 63, on which is pivotally mounted the shank' 64 of a hook B5, the sha-nk lying between a pair of collars 65 encircling the bolt between adjacent links of the two chains. The adjacent links on the two chains, which lie next to the rear beyond each bolt 63 are connected by a plate 6l' having an opening, through which hook 65 may be projected. The shank 64 of each hook has a pair of rollers 68 traveling in tracks BS extending along the double chain and behind it and the track is so formed that, as each hook passes beneath sprocket wheels t2, the hook is swung outwardly through its plate Sl and continues in projected position until the hook passes over the top of sprocket wheels 60, whereupon it is retracted.

The chute 5l has a vertical slot near its lower end, through which extends an agitator (Fig. 2) in the form of a plate l0 pivoted in its lower end on a bracket attached to the outer surface of the chute. The agitator is connected by a slot and pin connection to an arm 12 on a shaft '|3 mounted in bearings on the side members of the frame. Shaft i3 is provided with another arm I4 connected by a link 15 to a crank arm 16 on a transverse shaft ll mounted in bearings on the framework` As shaft 11 rotates, the agitator reciprocates through the slot in the chute toward and away from the vertical stretch of the double chain 59.

A pair of plates 'f3 extend forwardly from the forward ends of plates 48 to the vertical members of the frame, to which the edges of chute 5l are connected, and side plates 1S are mounted above plates i3 to shield the upper part of chain 59.

A rotary delivery or cloning wheel 8U is mounted on a fixed transverse shaft 8| supported on the framework and the wheel is provided with a pair of hooks 82, which may be projected through openings in the surface of the wheel or retracted in it. The hooks 82 are mounted on shafts 83 supported in bearings attached to the ends of the wheel and each shaft has an arm 84 connected by a connecting rod 35 to a hub Btc. One of the connecting rods is rigidly attached to the hub to act as a master connecting rod and cause the hub to rotate with the drum and the hub runs on bearings 86 encircling an eccentric 8l' fast on shaft 8|. The surface of wheel 80 lies close to the stretch of the double chain passing from sprocket wheels 60 to sprocket wheels 6| and the arrangement of the eccentric is such that each hook is fully projected from wheel at the point where the hook lies nearest to the chain on its approach thereto and is fully retracted later.

A beater wheel 88 is mounted on a transverse shaft 89 in bearings on the frame and it is provided with a plurality of flexible beating members 9U projecting from its surface in position to bear against the surface of the delivery wheel 8i), as the beater wheel rotates. A pressure roll 9| is mounted for rotation in the ends of arms S2 pivoted to the framework and rests upon the surface of the delivery wheel 80. A stiff bristle brush 93 is mounted on arms 92 to bear against the surface of the pressure roll and to prevent fiber, yarn, or similar foreign material from collecting on the pressure roll.

Towels carried by the delivery wheel 80 beneath the pressure wheel 9| are counted by an electronic counting device, one part 94 of which is mounted on the frame at one side of the delivery wheel just beyond its line of contact with the pressure wheel. the type which operates to count one unit each time a light beam traveling across the delivery wheel close to the surface thereof is interrupted.

A bracket S5 is mounted on the framework adjacent the surface of the delivery wheel ap-l proaching bottom center and the bracket carries' a cleaning brush 96 bearing on the surface of the delivery wheel. The part of the delivery wheel approaching the conveyor chain 59 and receding therefrom lies between two side plates 91 similar to plates 48 and lying on opposite sides of the upper part of the chain and the stretch between sprocket wheels and 6|. The beater members 90 on wheel 8B extend through the space between the two side plates. A cage 98 is mounted at its upper end on a rod 99 extending across the frame and the lower end of the cage is attached to the upper end of a chute which partially encloses the stretch of chain 59 between sprocket wheels 6| and 62. Beneath sprocket wheels 62, there is a cage IBI attached at one end to the lower fend of chute |90 and at the other to the bottom of chute 51.

The machine is driven by a motor |02 (Fig. 2) mounted on the frame and driving the input shaft of a gear reduction box |63 through a belt or chain |04. The output shaft of the box carries a sprocket wheel |95 connected by a chain |96 to a sprocket wheel on shaft |01 to whi-ch sprocket wheels 6| are fast. Chain |06 also drives a sprocket wheel on shaft 11, which carries a pair of sprocket wheels, one of which is connected by a chain |98 to a sprocket wheel |99 on a shaft H0 provided with a gear meshing with a gear fast to drum 46. |'The third sprocket wheel on shaft 1'! is connected by a chain ||2 to a sprocket wheel on a shaft |I3, which carries a gear meshing with a gear 4 on shaft 3|. Shaft |91 is connected by a chain l'la to a sprocket wheel on the shaft S9 of the beater wheel and to a sprocket wheel 80a secured to the delivery wheel 90.

At the start of operation of the machine, the gate carriage has been moved to its rearmost position on the main carriage by operation of motor 3l, which has rotated screw 35 and caused worm gear 34 to roll along screw 35, until a trip block on the gate carriage has struck the operating arm H of a switch Hl operating to shut off motor 3l. The gate 22 is then at the limit of .its rearward motion and a charge of towels is deposited in the first receptacle defined by the gate, the side plates 2|, drum 4B, etc. As the drum rotates, the hooks mounted therein are projected as they enter the bottom of the receptacle and the hooks, accordingly, engage the charge of towels. The reciprocating motion of gate 22 is synchronized with the travel of the hooks, so that the charge of towels is pressed against the drum 45, when the hooks are in the most effective position to engage the towels. The

'gate then recedes from the drum, so that the hooks can raise the towels engaged thereby free of the charge. On each backward motion of the main carriage, the gate carriage is advanced along the main carriage a short distance, so that the gate will more effectively press the charge against the drum, as the size of the charge del CIeaSeS.

.The single towels and groups of towels carried The counting device is of out of the first receptacle by the drum are released by the drum hooks at the top of the drum and are discharged from the drum into the second receptacle formed in part by chute 51, the scraper 58 insuring that all towels will be released from the drum. The towels in the second receptacle are agitated by the agitator 19, which is synchronized with the travel of hooks 65 on the double conveyor chain. These hooks are projected beyond the chain, as they enter the bottom of the second receptacle, and they engage towels in that receptacle and raise them over the top of sprocket wheels 69, at which point the hooks recede into the space between the chains. The towels are then carried along by the chains to be removed therefrom by the hooks 82 on the doffmg wheel 8E. At the place where the dofng wheel lies closest to the chains, the hooks on the wheel are moving in a direction opposite to that of the chain and the wheel hooks pick up towels lying on the chain and raise them to the place, where the towels are struck by the beating elements on the beater wheel 89. Any towels not rmly gripped by hooks 82 are knocked from the delivery wheel by the beating elements and are dropped back into the second receptacle or else pass down along the chain and drop to the bottom of chute |09, whence they are picked up by the hooks on the chain and raised into and through the second receptacle. The action of the beater wheel insures that only a single towel will be carried by each hook 82 on the delivery wheel and, as that towel is carried to the top of the delivery wheel, its hook is retracted into the wheel, and the towel is pressed against the surface of the delivery wheel by pressure wheel 9|. Beyond wheel 9|, the towel breaks the beam of the counting devi-ce, is counted, and is carried along and discharged by the delivery wheel. Any towels adhering to the delivery wheel are removed by a leather scraper a mounted on bracket 95 and lying in contact with the delivery wheel.

As the operation proceeds, the movement of the gate carriage along the main carriage reduces the size of the first receptacle so that the hooks on the rst conveyor 49 will more eiectively engage and remove towels from the charge. When the gate carriage has moved forward to the limit of its desired movement, trip block ||5 engages the operating arm ||9 of a switch H9, which starts motor 37 operating to move the gate carriage to its initial position at the rear of the main carriage. The machine is then ready to receive another charge of towels.

In the new machine, the soiled articles are disentangled and separated from one another in successive stages with the first two stages carried on in the receptacles by the operation of the conveyors. The final separation is effected in part by the action of the delivery wheel, which rapidly removes the articles from the chain conveyor with a change in the direction of their movement, and in part by the beater elements, which knock from the delivery Wheel any articles not firmly held by the wheel hooks but being carried along by adhesion. The quick reversal in direction of the articles being taken from the chain conveyor by the delivery wheel hooks is similar in effect to shaking the articles and such action plus that of the beater elements causes the articles to be fed singly to the counter and counted With so low a percentage of error as to be negligible.
