Abstract:
A coating device for supplying a liquid to a substrate, particularly in the form of an optionally printed web, foil, strip or sheet, comprises a reservoir for holding a quantity of liquid. A coating assembly is provided which is able and configured to take liquid from the reservoir and transfer it to the substrate. A supply delivers the liquid into the reservoir during operation. The supply is controllable and is able to lead a constant liquid flow into the reservoir. The reservoir is provided with a level detector capable and configured to detect a liquid level in the reservoir. Provided between the level detector tools and the coating assembly is a control which controls the coating assembly during operation on the basis of a detection (LS) of the liquid level in the reservoir in order to maintain the liquid level at a fixed value.
Abstract:
One embodiment of a container for transferring, storing, and dispensing paint indefinitely for touch-up painting by the use of a plurality of open-ably close-able apertures (310, 320) that cause transferring, storing, and dispensing of paint, in conjunction with a plurality of paint storage areas (1391, 153) that are independently open-ably sealable to allow for various functions such as, sealed storing of paint in one paint storage area while doing touch-up painting from another paint storage area, moving paint from external paint source to a paint storage area, moving paint between paint storage areas. Using standard (180, 190), as well as custom paint applicators allowing for ease of use, and with various features that allow for use with no clean up needed, such as replaceable components (121, 130, 170, 180, 190, 191, 192, 250) non-stick components (121, 130, 141), integral paint tray (130), paint containment features such as paint retaining walls (130) and paint catching recesses (130, 140). Carrying Tray (210) prevents spilling and holds replaceable parts (121, 130, 170, 180, 190, 191, 192, 250) for storage and transport. Other embodiments are described and shown.
Abstract:
Methods for storing and moving adhesive particulate to an adhesive melter are disclosed. An interior space of a supply hopper is filled with adhesive particulate. A transfer pump is actuated to generate a vacuum at an inlet of the transfer pump to actuate removal of the adhesive particulate from the supply hopper. A consistent minimized depth of the adhesive particulate located directly above the inlet is maintained with a shroud located within the interior space of the supply hopper. In addition, adhesive particulate can be received in an interior space of a container. An open space is maintained within the interior space of the container proximate the pump inlet, where the open space entrains gas to be drawn by the transfer pump. The transfer pump can be actuated to generate a vacuum at the pump inlet to cause removal of the adhesive particulate from the container.
Abstract:
A bulk adhesive transfer system for transferring adhesive particulate to a melter includes a bulk supply and a transfer device, which may define a hopper of the melter, a mobile bin, and/or a buffer unit. The transfer device is configured to receive unmelted adhesive particulate from the bulk supply and then be selectively docked with the melter to transfer the adhesive particulate to the melter. The bulk adhesive transfer system may also include a knife gate valve device, which includes a plurality of ports that sequentially open and close to control flow of the adhesive particulate towards the melter. The bulk adhesive transfer system simplifies refilling operations for a melter while enabling continuous operation of the melter, even when the transfer device is undocked for removal from the melter.
Abstract:
A resin dispensing apparatus includes a supply unit including a syringe having an internal space configured to hold a phosphor-containing resin. An agitator is disposed in the internal space. The supply unit is configured to rotate at least one of the syringe and the agitator to prevent settling of phosphor contained in the phosphor-containing resin. A discharge unit includes a cylinder having a discharge nozzle through which the phosphor-containing resin, received through a connecting pipe connected to the syringe, is discharged. A piston provides pressure to discharge the phosphor-containing resin through the discharge nozzle inside the cylinder.
Abstract:
The present invention relates to a pulsation damping system for a paint spray device for spraying paint including a pulsation damper for damping the pulsation of a paint stream, wherein the pulsation damper includes a housing, a chamber, a chamber inlet, a chamber outlet and a damping means. In this connection, an opening of the chamber outlet comprises a cross sectional area which is smaller than a cross sectional area of an opening of the chamber inlet, and as a result forms a throttle.
Abstract:
An adhesive dispensing system and method are configured to melt adhesive on demand and maintain the adhesive in a liquid state between dispensing cycles. The dispensing system includes a dispensing applicator with a manifold passage, a receiving device including a receiving chamber for holding a small amount of solid adhesive at the dispensing applicator and a first heating device for melting the adhesive on demand, and a second heating device at the manifold to maintain the temperature of the melted adhesive before dispensing. The receiving device is positioned adjacent to or partially nested within a manifold of the dispensing applicator such that the melted adhesive is delivered directly into the dispensing applicator. The second heating device applies heat energy to maintain the adhesive in the manifold passage as a liquid.
Abstract:
An adhesive bin (10) for storing and moving adhesive particulate (14) to an adhesive melter (12) includes a supply hopper (16), a transfer pump (62) operable to generate a vacuum, and a shroud (94). The supply hopper (16) has a sidewall (20, 22, 24, 26) and defines an interior space (36). The transfer pump (62) extends through the sidewall (22) and into the interior space (36). In addition, the shroud (94) is connected to the sidewall (22) and extends into the interior space (36) and at least partially surrounds an inlet (82) of the transfer pump (62).
Abstract:
When a discharge device and a filling device are connected to each other so as to fill a fluid into the discharge device, the mixing of air into the fluid is suppressed, and thereby a discharge failure caused by the mixing of air is suppressed. A discharge system includes a discharge device capable of being filled with and discharging a fluid for discharge, a filling device for filling the fluid into the discharge device, a connecting device for connecting the discharge device and the filling device to each other in a separable manner, a sealed space forming member for forming a sealed space, and a decompression device for bringing an inside of the sealed space into a negative pressure state.
Abstract:
A device for dispensing a heated liquid, such as a hot melt adhesive, includes a vertically oriented mounting plate; a melter subassembly including an adhesive manifold, a heater, and a pump adapted to dispense the heated liquid; a control subassembly adapted to control one or more components of the melter subassembly; and a subassembly cover coupled to the mounting plate for movement between an open condition and a closed condition. The subassembly cover thermally insulates the melter assembly from the control assembly when in the closed condition.
