Abstract:
A jetting dispensing module includes a module body with a fluid bore. A nozzle element is coupled to the module body. The nozzle element includes a fluid reservoir communicating with the fluid bore of the module body and a dispensing passage. A guide element includes a main guide bore and an internal fluid space in fluid communication with the fluid bore. A plunger is mounted for reciprocating movement within the module body. The plunger extends through the main guide bore and into the internal fluid space, and includes a distal end moveable between a fully retracted position spaced from the fluid reservoir and a fully extended position within the fluid reservoir but out of contact with the nozzle element.
Abstract:
A cooled hot melt adhesive material storage system includes a bin and a cooling unit. The bin receives and holds a supply of hot melt adhesive pieces, and includes an outlet for communicating hot melt adhesive pieces to a melter device. The cooling unit is operatively coupled with the bin, and is configured for cooling hot melt adhesive pieces contained in the bin.
Abstract:
A heat exchange device for heating liquid adhesive material to an application temperature suitable for an adhesive bonding application includes a body having an inlet configured to receive a flow of liquid adhesive material and an outlet configured to provide the liquid adhesive material to a dispensing device for the adhesive bonding application. A fluid passageway in the body connects the inlet and the outlet. The fluid passageway includes a thin slit section in the form of an elongated ring shape, having a length along a fluid flow direction between the inlet and the outlet, the thin slit section further having a first dimension and a second dimension transverse to the fluid flow direction. The first dimension and the length are substantially greater than the second dimension. The heat exchange device further includes a heating element for heating the liquid adhesive material flowing through the thin slit section.
Abstract:
An application apparatus includes a nozzle device (20) injecting a damping material from a nozzle hole (20a) to a vehicle body, an articulated robot (21) moving the nozzle device (20) relative to the vehicle body, a supply section including a supply pump (22), and a supply passage (27), and continuously driving the supply pump (22) to continuously supply the damping material from the supply pump (22) to the supply passage (27) in a substantially uniform amount, a return passage (33) branched from the supply passage (27) and returning the damping material to the supply pump (22), and a gun (32) and a return valve (34) switching a supply destination of the damping material between the nozzle hole (20a) and the return passage (33) based on information on applying the damping material to the vehicle body.
Abstract:
An adhesive dispenser includes: a vessel has an open top and a closed bottom, and defines an interior cavity; a handle is affixed on one side of the vessel; a lid with an adhesive charge port closes the open top; a pour spout opens through the lid and is positioned on a side of the cavity opposite the handle, the pour spout includes a channel formed in the cavity and the channel extends from the pour spout to adjacent the bottom of the cavity; and a heater including a heating element for melting adhesive placed in the cavity, and a fin extending axially from the bottom of the cavity. The method for dispensing includes pouring a liquid adhesive from the dispenser.

Abstract:
A cover assembly for a liquid adhesive applicator protects a user from burns in case the applicator is touched and provides additional insulation for the applicator, thereby saving energy. The cover includes a first side panel and a second side panel connected to each other by posts extending through and around the applicator. A front panel is secured between the first side panel and the second side panel. A first insulating sheet may be disposed between the first side panel and a first side of the applicator to provide further insulation. Similarly, a second insulating sheet may be disposed between the second side panel and a second side of the applicator.
Abstract:
A buffer unit is configured to store and transfer adhesive particulate to at least one adhesive melter. The buffer unit includes a buffer bin defining an interior space configured to hold a bulk supply of adhesive particulate with an agitator plate positioned within the housing at a non-horizontal orientation. A vibration generating mechanism is coupled to the agitator plate so that vibration is transmitted into the adhesive particulate to form a flow of fluidized adhesive particulate which flows toward at least one pump inlet. The buffer unit breaks up clumps of coalesced adhesive particulate to avoid clogging the pump inlet, while also ensuring that all adhesive particulate in the buffer bin can be removed at the pump inlet. Additionally, makeup air used by pumps to generate vacuum at the pump inlet does not need to be drawn through the entire bulk supply of adhesive particulate.
Abstract:
A melter for heating and melting particulate hot melt adhesive into a liquefied form is disclosed. The melter includes a heated receiving device having an interior with an inlet configured to receive the particulate hot melt adhesive and an outlet. A flexible hopper holds a supply of the particulate hot melt adhesive and a particulate hot melt adhesive feed device allows the particulate hot melt adhesive to be directed from the flexible hopper to the inlet of the heated receiving device.
