Definitions

  • This invention relates in general to the washing of cloth goods, and, more particularly, to improvements in continuous batch type washing machines and methods for operating same.
  • each of a succession of drums or baskets is mounted for rotation within a bath of liquor during each washing cycle, each bath being contained with an individual compartment of a succession of compartments forming the tunnel.
  • Means are provided for transferring cloth goods from each drum into the next successive drum, intermediate washing cycles, and for causing liquor to circulate through each drum compartment and maintaining a desired level thereof making up the bath during each washing cycle.
  • successive batches of cloth goods may be fed into the leading drum at front end and removed from the trailing at the rear end following passage through the intermediate drums.
  • water may be circulated through one or more drum compartments at the front portion of the machine for pre-wash purposes and soap may be added to the water circulated through several of the following drum compartments in the main wash stage of the machine.
  • the goods may then be rinsed with water circulated through one or more succeeding drum compartments, and then bleached, starched or otherwise treated with chemicals added to the water circulated through the final drum compartments.
  • liquor may not pass entirely through the machine from one end to the other-e.g., certain of the different types of liquor may be prevented from commingling.
  • each drum has coaxial inlets and outlets in its opposite sides, and the goods are transferred through the outlet in one drum into the inlet in the next drum by means of a scoop-like member mounted within each drum and extending through openings in intermediate walls of the tunnel which divide it into compartments.
  • the scoops are of such construction that, when the drums are oscillated within limits, the goods therein are not transferred, but instead tumbled so as to promote thorough washing of the clothes.
  • an inclined wall of the scoops assumes a position in which the goods are caused to slide downwardly thereover into the next drum.
  • the drum After a relatively short interval, during which the goods are transferred, the drum resumes its oscillatory motion during a subsequent wash cycle.
  • the cloth goods may be tumbled and washed during repeated full circle rotations of the drum in the opposite direction.
  • successive batches of different goods may create an incompatibility when fed through the machine in one sequence, and thus in accordance with one formula, they may not when fed therethrough in the opposite order, and thus in accordance with another formula.
  • .while dyed goods and white goods may create an incompatibility if the white goods follow the dyed goods, as above described, they may not if the order is reversed.
  • the reasons for incompatibility may be other than or in addition to color, as in the above-described formula of white goods which follow goods containing dyestuff which is not colorfast.
  • temperature may be a factor in determining the incompatibilities of a given formula in that the liquor in one drum compartment may be too hot for the goods which are to enter it next, or for the goods in a drum compartment into which such liquor is to flow next.
  • Chemicals may also be a factor in that the liquor in a given drum compartment may contain bleach which is incompatible with colored goods which are to enter it next.
  • liquor in a given drum compartment may be very dirty, due to soil from the goods washed in that compartment, and thus incompatible with clean goods which are next to enter it. It is thus in these senses, and other senses which will be apparent to those skilled in the art, that the term "incompatibility" is used throughout this application.
  • the present invention provides a continuous batch type washing machine which comprises, as in prior machines of the general type described, a succession of drums each of which is rotatable within a bath of liquor contained within an individual compartment of a succession of compartments during each wash cycle and means for transferring cloth goods from each drum into the next successive drum intermediate washing cycles, and for causing liquor to circulate through each drum compartment and from at least one compartment into an adjacent compartment of a pair of successive drum compartments, while being maintained at a desired level therein during a wash cycle.
  • the machine of the present invention comprises means which are operable, at the beginning of each wash cycle, and when there is an incompatibility of the liquor in the one drum compartment with the goods in the adjacent drum compartment, for interrupting the circulation of liquor from said one into said adjacent drum compartment and diverting it elsewhere, and for replacing the liquor which the adjacent drum compartment was to receive from said one drum compartment with liquor compatible with the goods in the adjacent drum compartment, together with means which are operable, at the end of each wash cycle, and when there is an incompatibility of liquor within the next successive drum compartment of said pair of compartments into which the goods are to be transferred upon completion of the wash cycle, for draining the liquor therefrom, and at the beginning of the next wash cycle, adding liquor to the next successive drum compartment into which such goods have been transferred which is compatible therewith in order to replace the liquor which was drained therefrom.
  • the liquor may be caused to circulate from at least one drum compartment to the next successive drum compartment of a pair of adjacent drums.
  • the liquor may also be caused to circulate from at least one drum compartment to the next preceding drum compartment of a pair of adjacent drum compartments.
  • liquor in one stage of the machine, liquor may be caused to flow into the preceding drum compartment, and thus in counterflow relation with respect to movement of the goods through the machine, and, in another stage, liquor may be caused to flow into the next successive drum compartment, and thus in a cocurrent relation with respect to the direction of movement of the goods through the machine.
  • the preferred and illustrated embodiment of the machine includes means for draining liquorfrom each drum compartment and filling each drum compartment with liquor at a relatively fast rate, so that, in the event of an incompatibility between the liquor in a given drum compartment and the goods in the next preceding drum compartment, as above described, the liquor in the given drum compartment may be drained therefrom, just prior to transfer of the goods thereto, and replaced with liquor compatible with the goods following such transfer and at the start of the next wash cycle. Also, after the circulation of the liquor from the one drum compartment into the other drum compartment has been interrupted and diverted elsewhere, at the beginning of a wash cycle, it may be reestablished at the start of the next wash cycle when the liquor in such one drum compartment is compatible with the goods in the other drum compartment. In any event, during operation of the machine, the means for so draining and filling, as well as the means for interrupting circulation and diverting it elsewhere, may be operated in response to observations of the incompatibilities of the particular formula of goods being moved through the machine.
  • a machine of this general type may be so modified as to permit its operation in accordance with the present invention with relatively little additional cost.
  • the existing parts and their functions may be retained without interfering with the operation of the present invention.
  • these additional parts may be programmed for operation automatically in response to the incompatibilities of the formulas, and thus with a minimum of personal attention on the part of the operator of the machine.
  • the overall machine which is indicated in its entirety by reference character 20, includes a succession of drums generally indicated by reference character 21 each of which is rotatable during each washing cycle within a bath of liquor contained within individual compartments 22 of an elongate tunnel 23 intermediate dividing walls 26.
  • the front (leftmost) compartment of the tunnel has a .central inlet opening 24, the rear (rightmost) compartment of the tunnel has a central outlet opening 25, and coaxial openings are formed in the dividing walls between adjacent compartments.
  • drums there are eight successive drums as indicated by the numerals assigned to them, each rotatable within an individual compartment to enable certain assigned functions to be performed therein during each wash cycle, as will be described, although this number and arrangement of the successive drums and compartments is merely typical.
  • the drums are mounted in any suitable manner within the tunnel for coaxial rotation in opposite directions within each compartment, as shown, for example, in the aforementioned prior Patent No. 4,236,393.
  • each drum has a scoop 28 which is of such construction that, upon rotation of the drum in one direction in a predetermined rotational position, as indicated diagrammatically in Figs. 2 to 9, it transfers goods from that drum into the next succeeding drum by sliding downwardly over an inclined wall thereof.
  • the scoop or transfer means is also of such construction that, when oscillated within limits, or when rotated continuously in the direction opposite to that in which transfer takes place, the clothes will be caused to tumble within the drum in order to promote treatment of the cloth goods.
  • transfer cycle means that interim the operation of the machine that the scoop or other transfer means occupies that position in which the goods are actually moved from one drum to the other
  • wash cycle means those other interims prior to and following each transfer cycle-e.g., prior to or following movement of the scoop into or out of its transfer position.
  • Machine 20 is preferably of modular construction wherein each compartment and the drum rotatable therein provides an individual module adapted to be assembled with other modules into a tunnel of desired construction.
  • drum 1 is devoted to a pre-wash
  • drums 2 and 3 are devoted to a main wash.
  • the cloth goods are adapted to be rinsed in the drums 4 and 5, and to be chemically treated in the drums 6, 7 and 8.
  • This chemical treatment may include a bleaching operation in the drums 6 and 7, and a starching operation in the drum 8.
  • dirty goods are introduced into the inlet chute 27 by means of a conveyor 29, and clean goods are received by a conveyor 30, from drum 8 for transport to an extractor of some type.
  • liquor in the form of water is circulated into the compartment for pre-wash drum 1 by means of a conduit 31 leading from a container 32 for the water.
  • the bath is maintained at a desired level in drum 1 by means of a weir indicated diagrammatically by loop L, which, as will be described in connection with Fig. 10, is preferably mounted on the outside of the tunnel. Water passing over the weir is drained to a sewer or other suitable place for disposal, as indicated by the downwardly pointed, long leg to the loop.
  • Conduit 31 includes a parallel circuit having both a line 33 for fast- filling the compartment for drum 1 and a line 34 for filling it at a slow rate.
  • Liquor in the form of water is also added to the compartment for drum 5 at a relatively slow rate, as indicated by letters "S-F" above the arrow leading downwardly into the compartment, and is caused to circulate from the compartment for drum 5 into the compartment for drum 4, from the compartment for drum 4 into the compartment for drum 3, and from the compartment for drum 3 into the compartment for drum 2, by means of conduits 35 connecting adjacent compartments with one another.
  • a similar loop having a weir at the upstream end of each such conduit maintains a desired level of liquor in the compartment to which it is connected.
  • loop L leading from the compartment for drum 2 has a drain leg, as in the case of the loop leading from the compartment for drum 1.
  • liquor added to the compartment for drum 5 will be circulated through that compartment as will as compartments for drums 4, and 2 in counterflow relation with respect to the direction of movement of the goods through the machine.
  • chemical in the form of soap may be added to the liquor in the compartments for drums 2 and 3, as it is circulated therethrough from the compartments for drums 4 and 5.
  • additional chemical may be added to the liquor in each of compartments for drums 2 and 3 in order to augment chemical drained therefrom with liquor in the compartment, as will also be described.
  • liquor in the form of water which may contained bleach is circulated through and maintained at a desired level within the compartments for each of the drums 6 and 7.
  • water is supplied to the' compartment for drum 6 through a slow-fill line indicated by the letters "S-F" above the arrow in Fig. 1, and bleach is added to the water through a separate connection (not shown) to form the liquor which is circulated from this compartment into the compartment for drum 7 through a connecting conduit 36.
  • the bath is maintained at a desired liquid level within the compartment for drum 6 by means of a loop L having a weir at the inlet end of connecting conduit 36, similarly to conduit 35, and by means of a loop L in the compartment for drum 7 having a drain leg therefrom similar to those above described.
  • the liquor flows in a co-current relation with respect to the movement of the goods through the machine.
  • the compartment for drum 8 is similar to the compartment for drum 1 in that, in the absence of an incompatibility, as will be described to follow, liquor is circulated through it independently of circulation from or into adjacent compartments.
  • liquor is circulated through it independently of circulation from or into adjacent compartments.
  • water is supplied to the compartment for drum 8 through a slow-fill line indicated by the letters "S-F" above the arrow leading downwardly into the compartment, and starch is added to the water to form liquor which is maintained at a. desired level in the compartment by means of a loop L having a drain leg leading to a suitable place of disposal outside of the compartment.

  • the compartments for drums 2 to 4 and 7, as well as those for the drums 5, 6 and 8, are provided with means for adding liquor therethrough at a slow rate, as indicated by the letters "S-F” above arrows leading thereto, and each of drums 2 through 8 are also provided with means for adding liquor thereto at a fast rate, as indicated by the letters "F-F” above an arrow leading downwardly into the upper end of the particular compartment.
  • the letters "C-A" above an arrow extending downwardly into the compartments for drums 2, 3, 6, and 8 indicate lines through which a chemical augmentation may be added thereto.
  • These chemical augmentations may comprise, in a typical machine such as that illustrated, and in addition to soap in the case of the compartments for the main wash drums 2 and 3, as previously described, bleach in the case of the compartments for the drums 6 and 7, and starch in the case of the compartment for the drum 8.
