HOT MELT ADHESIVE DISPENSING SYSTEM HAVING AN INTEGRAL FLUID AND ELECTRICAL CONNECTOR
Cross-Reference to Related Application
[0001] This application claims the priority of Application Serial No.
61 /553,578, filed October 31 , 201 1 (pending), the disclosure of which is hereby incorporated by reference herein.
Technical Field
[0002] This invention generally relates to hot melt adhesive dispensing systems including components such as melters, heated hoses, manifolds and valve modules for dispensing hot melt adhesive.
Background of the Invention
[0003] Various manufacturing processes involve the transfer of a pressurized heated hot melt adhesive from a source, such as a melter tank, through heated lengths of flexible hose to a hot melt adhesive dispensing device, such as an applicator gun comprising a manifold and attached valve module. The gun dispenses liquefied thermoplastic material, such as hot melt adhesive onto any desired substrate in the form of a continuous bead or filament or as intermittent beads or filaments, or as droplets or other types of random or specific patterns. Thermoplastic materials, such as hot melt adhesives, may be liquid or solid at room temperature. Such thermoplastic materials are commonly pumped from a source, such as a melter, through a heated hose to the hot melt adhesive dispensing device. Generally, conventional heated hoses include a central conduit for conveying the heated thermoplastic material from the source to the hot melt adhesive dispensing device and multiple plies of thermal and electrical insulation, heaters, and electrical wiring surrounding the central conduit.
[0004] Many manufacturing processes utilize production line techniques in which there is a fixed maximum distance between the supply, such as the melter, and the target surface. In these situations, the required length of hose between the source and the hot melt adhesive dispensing device may be fixed approximately at that maximum distance. In manufacturing the heated hoses and applicator guns, the hoses are made to include separate electrical cord sets. An example is shown in U.S. Patent Publication No. 2005/0008353, published on January 13, 2005, the disclosure of which is hereby fully incorporated by reference herein. Independently coupled connectors are provided for transporting the liquid hot melt adhesive from the hose to the applicator gun, and for supplying power to electrical components associated with the applicator gun, such as a electrical resistance heaters (e.g., cartridges), resistance temperature detectors (RTD's), and/or electric solenoids associated with the applicator gun. This type of assembly presents various drawbacks, such as manufacturing complexities and costs.
[0005] Fig. 1 illustrates a conventional portion of a hot melt adhesive dispensing system comprising a hot melt adhesive applicator gun 10 with a valve module 12 and an attached manifold 14. An electrical cord or cable 16 and attached connector 18 extends from the manifold 14. A hot melt adhesive hose 20, which may be of the above-mentioned type, includes a hot melt adhesive connector 22 that mates with a complementary connector 24 coupled with the manifold 14. Another electrical connector 26 with an attached electrical cable 30 couples with the connector 18 of the electrical cable or cord 16 that extends from the manifold 14. This connector 26 couples to the hose 20 via electrical cable 30, which connects electrically to an RTD and an electrical resistance heater within the hose 14 for purposes of heating the hot melt adhesive carried by the hose 14 and controlling the application temperature of the adhesive. In this conventional system, it will be appreciated that separate and independent connections must be made for the fluid and electrical portions of the system. In addition, an electrically activated solenoid valve 40 with an electrical signal cable 42 and an air supply line 44 is shown. The solenoid valve 40 is mounted to the manifold and supplies actuation air via a pair of conduits or pipes 46, 48.
[0006] It would be desirable to provide a heated flexible hose with features for improving the connection of both fluid and electric components associated with a hot melt adhesive dispensing system. Summary
[0007] In one embodiment, the invention generally comprises a heated hose for transporting a heated thermoplastic hot melt adhesive from a heated hot melt adhesive source to a hot melt adhesive dispensing device. The hose includes a thermally insulated conduit having an inlet end adapted to be coupled in fluid communication with the heated hot melt adhesive source and a discharge end adapted to be coupled in fluid communication with the hot melt adhesive dispensing device. An electrical heating element extends between the inlet end and the discharge end of the conduit. The heating element is adapted to generate and transfer heat to hot melt adhesive within the conduit.
At least a first integral electrical and fluid coupling is provided and is attached to one of the inlet end or the discharge end of the conduit. The integral electrical and fluid coupling includes first electrical contact elements and a first fluid connector configured for securing the first integral electrical and fluid coupling to one of the supply or the hot melt adhesive dispensing device.
[0008] In another embodiment or aspect, a second integral electrical and fluid coupling is attached to the other of the inlet end or the discharge end of the conduit and includes second electrical contact elements and a second fluid connector configured for securing the second integral electrical and fluid coupling to the other of the supply or the hot melt adhesive dispensing device.
The first integral electrical and fluid coupling can further include a second fluid connector. In this manner, the first fluid connector can carry hot melt adhesive and the second fluid connector can carry air to the hot melt adhesive dispensing device. Electrical wiring is preferably coupled with the conduit and is adapted to provide electrical power to an actuator associated with the hot melt adhesive dispensing device. The first electrical contact elements include elements electrically connected with the electrical wiring, which may generally be considered an electrical supply for components attached to the outlet end of the hose. Other types of electrical supplies may be used alternatively or additionally to the wiring. The electrical contact elements are electrically coupled with the electrical heating element and are adapted to be electrically coupled with a heater associated with the hot melt adhesive dispensing device.
[0009] In another embodiment, a dispensing apparatus is provided comprising a heated hose for transporting a heated thermoplastic hot melt adhesive from a heated hot melt adhesive source. The apparatus includes a thermally insulated conduit having an inlet end adapted to be coupled in fluid communication with the heated hot melt adhesive source and a discharge end adapted to be coupled in fluid communication with the hot melt adhesive dispensing device. An electrical heating element extends between the inlet end and the discharge end of the conduit. The heating element is adapted to generate and transfer heat to hot melt adhesive within the conduit. At least a first integral electrical and fluid coupling is provided and is attached to the discharge end of the conduit. The first integral electrical and fluid coupling includes first electrical contact elements and a first fluid connector. The apparatus includes a hot melt adhesive dispensing device having a second integral electrical and fluid coupling. The second integral electrical and fluid coupling is configured to couple to the first integral electrical and fluid coupling so that electrical power and fluid are supplied to the hot melt adhesive dispensing device. A third integral electrical and fluid coupling may be further provided and attached to the inlet end of the conduit. The third integral electrical and fluid coupling includes third electrical contact elements and a third fluid connector configured for securing the third integral electrical and fluid coupling to the hot melt adhesive supply.
[0010] The first integral electrical and fluid coupling can further include a second fluid connector. In this manner, the first fluid connector is adapted to carry hot melt adhesive and the second fluid connector is adapted to carry pressurized air to the hot melt adhesive dispensing device, such as for actuating the adhesive dispensing device and/or supplying process or pattern air to the dispensing device for purposes of producing a desired dispensing pattern. The hot melt adhesive dispensing device may further include an electrical actuator for operating the dispensing device between open and closed states to respectively allow and prevent discharge of the hot melt adhesive from the dispensing device. For example, the electrical actuator may be a solenoid coupled with or integrated wholly or partially into the dispensing device.
Electrical wiring is coupled with the conduit and adapted to provide electrical power to the electrical actuator. The first electrical contact elements include elements electrically connected with the electrical wiring. The hot melt adhesive dispensing device may further include an electrical heater, and in this case the electrical contact elements are electrically coupled with the electrical heating element of the hose and are adapted to be electrically coupled with the electrical heater of the hot melt adhesive dispensing device when the first and second integral electrical and fluid coupling are connected together.
[0011] Additional aspects, features and advantages will become more readily apparent to those of ordinary skill upon review of a detailed description of illustrative embodiments of the invention below, taken in conjunction with the accompanying drawings.

Detailed Description
[0017] In the figures, like reference numerals refer to like elements and function. For the sake of brevity, it will be understood that repeated description of elements throughout the description is not necessarily given. Fig. 2 illustrates a hot melt adhesive dispensing system 50 including a hot melt adhesive melter unit 52 coupled with one end 54b of a hot melt adhesive hose
54 and an applicator gun 56 coupled with an opposite end 54a of the hose 54.
The hot melt adhesive melter unit 52, the hose 54 and the hot melt applicator gun 56 may be of any desired configuration and design. As described further below, an integral electrical and fluid connector 60 is provided on at least the end 54a of the hose 54 coupled to the hot melt adhesive applicator gun 56 and thereby couples fluid and electrical components associated with the hose 54 and the gun 56. An identical electrical and fluid connector 62 is provided at the opposite end 54b to connect the hose 54 to the melter unit 52.
[0018] Referring to Fig. 3A, the connector 60 specifically includes a coupling 60a with electrical connectors, including but not limited to pins and/or prongs 64a for supplying electricity to one or more of a solenoid (described in connection with Fig. 4, below) associated with or incorporated into the adhesive applicator gun 56, an RTD (resistance temperature detector) in the gun manifold 66, an RTD within the hot melt adhesive hose 54, and electrical heater cartridges or elements associated with the applicator gun 56 and/or hose 54.
As shown in Fig. 5, an electrical heating element 53 is shown incorporated into the hose 54 for purposes of heating the melted adhesive flowing through the hose 54. The heating element 53 may be electrically coupled with the pins or prongs 64a for purposes of supplying electrical power to the heater element 53, for example, when the connector 60 is on the inlet end 54b of the hose 54.
Electrical wiring 55 is connected to the electrical pins and prongs 64a. As further shown in Figs. 3A and 5, the gun manifold 66 is coupled to an adhesive dispensing module 1 2. A first conduit connector 70a is provided for supplying pressurized actuation air to the applicator gun 56, and a second conduit connector 72a is provided for supplying the hot melt adhesive to the applicator gun 56. An end portion 74 of the hose 54 is shaped to be received within a complementary connector 76 of the applicator gun 56 as further shown in Fig.
3B. Receptacles 64b, 70b, 72b corresponding to the respective prongs 64a and conduit connectors 70a, 72a are provided in a portion 80 of the connector
76 affixed to the applicator gun 56. As shown in Figs. 3C and 3D, a translatable and rotatable lock element 82 is moved over the coupling 60a associated with the end 54a of the hose 54 and is translated and partially rotated so that a projection 90 on the complementary connector 76 engages a recess 92 to ensure that the connection between the hose 54 and the applicator gun 56 is securely made. As shown in Figs. 3C and 3D, the movable lock element 82 is moved over the projection 90 such that the projection 90 slides within an L- shaped slot 92 including a recess 94 extending along the axis of the hose 54 and a further recess 96 extending transverse to the lengthwise recess 94, into which the projection 90 slides when the lock element 82 is rotated. [0019] Fig. 4 illustrates another embodiment in which the hose connector 54a is held in a mounting member 97 and the hose 54, hose connector 54a, electrical and fluid connector 60 and applicator gun 56 are rotatably adjustable with respect to the mounting member 97 generally in a direction indicated with the arrow 1 00 and the adjustment may be fixed at the desired angle in a suitable manner, such as by using a set screw 102 in the mounting member 97 and turning the set screw 102 into a threaded hole 99 and against the hose connector 54a. Thus, the particular angle of the applicator gun 56 and the adhesive dispensing module 12 relative to the mounting member 97 is adjustable. Figure 4 further illustrates a solenoid valve 104 attached to or integrated with the gun 56 for supplying actuating air and/or process or pattern air to the dispensing module 1 2. The solenoid 104 receives pressurized air and electrical power from the hose 54 and the electrical and fluid connector 60 described, for example, in connection with Fig. 3A. The solenoid 104 can then control the supply of actuation air to the dispensing valve/module 1 2 for purposes of operating the module 12 to dispense liquid such as hot melt adhesive.
[0020] Fig. 5 is a side elevational view of the applicator gun 56 coupled to the hose 54 and partially cross-sectioned to show electrical and fluid connections made with the integral electrical and fluid connector 60. In particular, the electrical connections using pins 64a and receptacles 64b are shown as are the hot melt adhesive and air connections using conduit connectors 70a, 72a and receptacles 70b, 72b. Thus, only a single coupling is necessary to supply the applicator gun 56 and the adhesive dispensing module 12 with electrical power, adhesive, and air.
