Abstract
Abstract A ware reject apparatus is employed in a glassware forming machine in which a plurality of molds are operated to supply a corresponding plurality of bottles in series on a common output conveyor. The apparatus permits malformed bottles coming from a particular mold to be eliminated from the conveyor by means of an ejector mechanism mounted adjacent the conveyor and operated by an electrical sequence timer driven in synchronism with the conveyor. A selector panel is connected with the sequence timer and has a plurality of manually operated switches corresponding respectively to each of the molds in the glassware forming machine. When a particular mold is malfunctioning and producing a low quality bottle, the corresponding switch on the selector panel is actuated and electrical timing signals from the sequence timer cause the ejector mechanism to schematically remove each of the bottles produced by the malfunctioning mold.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
142 words
A ware reject apparatus for a glassware forming machine or the like supplying articles from a plurality of molds in series on a common output conveyor comprising: sequencing means having an input member connected with the forming machine for producing phased timing signals for each article from the plurality of molds in the series on the output conveyor; selector means connected to the sequencing means and having a plurality of switches corresponding to the plurality of molds for transmitting selected timing signals from the sequencing means; ejector means for removing selected articles in the series from the conveyor; and ejector control means interconnecting the selector means and the ejector means for actuating the ejector means in response to the timing signals transmitted by the selector means, the control means also having cutoff means for limiting the actuating time of the ejector means.
Claim 2
Dependent Claim
142 words

Claim 3
Dependent Claim
57 words
A ware reject apparatus as defined in claim 1 wherein the sequencing means includes a rotor arm rotatable about a rotor axis and connected for rotation to the input member, and a set of circuit completing members actuated by the rotor arm and distributed in a circular scanning array about the rotor axis adjacent the rotor arm.
Claim 4
Dependent Claim
67 words
A ware reject apparatus as defined in claim 2 wherein the sequencing means includes at least two rotor arms mounted coaxially on the same rotor axis and two sets of circuit completing members distributed in circular arrays about the rotor axis adjacent the respective rotor arms; and further includes means for adjusting the rotational positions of the rotor arms relative to one another about the rotor axis.
Claim 5
Dependent Claim
45 words
A ware reject apparatus as defined in claim 3 wherein the sequencing means comprises a support frame rotatably adjustable about the rotor axis independently of the means for adjusting the rotor arms relative to one another, the circuit completing members being connected with support frame.
Claim 6
Dependent Claim
41 words
A ware reject apparatus as defined in claim 2 wherein the set of circuit completing members comprises a set of magnetically sensitive proximity switches and the rotor arm comprises a magnetic wand scanned sequentially adjacent each proximity switch of the set.
Claim 7
Dependent Claim
66 words
A ware reject apparatus as defined in claim 1 wherein the ejector means includes an electrically actuated solenoid; the ejector control means comprises an electrical actuating circuit connected with the solenoid and responsive to each of the timing signals transmitted by the selector means; and the cutoff means includes a limiting circuit cutting off the electrical actuating circuit a preselected interval after actuation of the solenoid.
Claim 8
Dependent Claim
72 words
A ware reject apparatus as defined in claim 6 wherein the actuating circuit and the limiting circuit jointly include first and second silicon controlled rectifiers, a commutating capacitor interconnecting the anodes of the rectifiers and a timer circuit, the gate of the first silicon controlled rectifier being connected to the selector means for receiving the timing signals and the gate of the second silicon controlled rectifier being connected to the timer circuit.
Claim 9
Dependent Claim
43 words
A ware reject apparatus as defined in claim 7 wherein the electrically actuated solenoid of the ejector means is connected in series with the first silicon controlled rectifier and the anode of the first silicon controlled rectifier is connected to the timer circuit.
Claim 10
Dependent Claim
20 words
A ware reject apparatus as defined in claim 8 wherein the timer circuit includes a serially connected resistor and capacitor.
Claim 11
Dependent Claim
91 words
A ware reject apparatus as defined in claim 1 wherein the plurality of switches in the selector meanS produce timing signals in the form of timing pulses having leading and trailing edges associated with the opening and closing of the switches; and wherein the ejector control means is connected with the plurality of switches and is responsive to the leading edge of the timing pulses to actuate the ejector means and the cutoff means limits the actuating time of the ejector means independently of the trailing edge of the timing pulses.
