    Abstract: Methods and apparatus are disclosed for spraying powder into the interior of welded hollow can bodies from a spray gun mounted to the welding arm of a can forming machine. The spray gun can either apply a stripe of highly charged powder on the welded seam areas of hollow can bodies, or can simultaneously apply a coating of powder having a first thickness on the longitudinally welded seam areas and a second thickness less than the first thickness on the remainder of the interior surface. Air is vented off from the powder flow being transported through the welding arm so that the powder to air ratio is increased. Air is introduced at the downstream end of the welding arm to provide a suction force to help draw the powder flow through the welding arm and to increase the velocity of the powder flow for better tribo charging of the powder in the gun and to improve spray pattern stability. A flow of cleaning air through the powder spray gun prevents powder from collecting on the front surface of an offset nozzle secured to the spray gun. The gun assembly is affectively grounded to prevent arcing, and has an exterior shape which has been geometrically configured to improve powder coating of the can. A collector hood surrounds an input conveyor on which cans are transported while being spray coated and an output conveyor which removes the cans at a higher speed than at which they traveled on the input conveyor. The collector hood has two operating conditions for collecting oversprayed powder from between the cans during the spraying operation or directly from the gun when the cans are not being sent down the line.

    Abstract translation: 公开的方法和装置用于从安装到罐形成机的焊接臂的喷枪将粉末喷涂到焊接的中空罐体的内部。 喷枪可以在中空罐体的焊接区域上施加一条高度带电的粉末，或者可以在纵向焊接区域上同时施加具有第一厚度的粉末涂层，并且在第一厚度上小于第一厚度的第二厚度 内表面的其余部分。 从通过焊接臂输送的粉末流中排出空气，使得粉末与空气的比率增加。 在焊接臂的下游端引入空气以提供吸力，以帮助将粉末流动通过焊接臂，并且增加粉末流的速度，以更好地摩擦带电的枪中的粉末并改善喷雾模式 稳定性。 通过粉末喷枪的清洁空气流阻止粉末收集在固定到喷枪上的偏移喷嘴的前表面上。 喷枪组件被有效地接地以防止电弧，并且具有几何构造以改善罐的粉末涂层的外形。 收集器罩围绕输入输送机，其上喷涂有罐头，并且输出输送机以比它们在输入输送机上行进的速度更高的速度移除罐头。 收集器罩具有两个操作条件，用于在喷洒操作期间从罐之间收集过度喷射的粉末，或者当罐没有被下送到管线时直接从喷枪收集。

    Abstract: A tribo-electric powder spray gun includes a diffuser for mixing powder with a conveying gas, a charging portion downstream of the diffuser, and a sprayhead at the outlet of the charging portion for dispensing the charged powder. The charging portion has an inner core removably positioned within a hollow outer cylinder with an annular gap formed between the outer cylinder and inner core providing a charging flowpath for the powder. The inner core and the outer cylinder have undulating or wavy charging surfaces made of an electrically insulating material, so that the annular gap provides a tortuous path for the powder, enhancing powder contact and the charge imparted to the powder. Grounding is provided by surface conduction of the electrically insulating contact material through a ground ring located outside the powder path at the inlet to the charging portion of gun where the greatest amount of charging occurs. By locating the ground ring outside the powder path, the ground ring is kept clean and the amount of charging surface is maximized. The inner core and the outer cylinder are longitudinally symmetrical to facilitate re-assembly.

    Abstract: A flat spray nozzle for a powder spray gun comprises a nozzle body formed with an axial powder flow passageway, a pair of spaced powder discharge slots intersecting the powder flow passageway and a bore located between the powder discharge slots. The bore in the nozzle body receives an electrode which extends forwardly of the spray nozzle, between the powder discharge slots for electrostatically charging particulate powder material emitted from the powder discharge slots without disrupting the spray pattern of particulate powder material.

    Abstract: An apparatus and method for determining the feasibility of performing a programmed sequence of motions with a robot. Included is a work robot at a first location having a plurality of power-driven, signal-controlled, relatively massive links interconnected to permit relative motion in plural degrees of freedom, the work robot having a given mechanical response characteristic. Associated with each link of the work robot is a position transducer which generates a signal representative of the actual position of its associated work robot link. Also included is a portable, relatively lightweight, manually manipulable simulator robot located remote from the work robot. The simulator robot has a plurality of different interconnected links adapted for manual movement in different degrees of freedom for setting a program of desired mechanical responses, with the links and degrees of freedom of the simulator robot simulating those of the work robot. Associated with each link of the simulator robot is a position transducer for generating a signal representative of the position of its associated simulator robot link. A signal recorder is provided at the location of the simulator robot for storing the position signals representative of the program of desired mechanical responses imparted to it by the operator. A work robot controller is provided at the site of the work robot which is responsive to the stored position signals for manipulating the work robot links to perform the movements corresponding to the program of desired mechanical responses limited only by the given mechanical response characteristic of the work robot. An analyzer responsive to the actual and desired position signals of the work robot links is provided for generating error signals correlated to the extent to which the work robot is capable of performing the program of desired mechanical responses manually imparted to the simulator robot. An indicator responsive to the analyzer provides a humanly perceptible indication of the feasibility.
