Abstract
Abstract Disclosed herein is a device for automatically varying the operating speed of a cigarette packaging machine in response to the presence or absence of defective groups of cigarettes to be packaged. The device includes a sensing member for sensing the number of cigarettes in a group, and for sensing the amount of tobacco in each cigarette. Control means are provided to maintain the operating speed of the machine at a high rate until a defective group of cigarettes is sensed by the sensing member, whereupon the operating speed is decreased to prevent malfunctions which may otherwise result from operational changes due to the detection of such defective groups. The control means operates to again speed up the machine after a predetermined duration of sensing by the sensing member during which no defective groups of cigarettes are detected.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
305 words
In an improved high speed cigarette packaging machine including means for providing cigarettes in groups in which said cigarettes in each group are disposed in a juxtaposed and overlying multilayered arrangement, sensing means for detecting the completion of each said group of cigarettes and the amount of tobacco within each cigarette, ejecting means for ejecting defective groups of cigarettes from the machine, and means for feeding wrapping paper for use in wrapping up said groups of cigarettes in multi-sheet casings, the improvement comprising means for automatically varying the operating speed of said machine, upon the sensing of a defective group of cigarettes, including electrical motor means for driving the machine at two different speeds; first electroswitching means for coupling between a potential source and said electrical motor means for controlling said motor means to operate at said two different speeds, second electroswitching means connected to said first electroswitching means for controlling the energization thereof, time-delay switch means and third switching means connected to said second electroswitching means for controlling the energization thereof, said first electroswitching means being connected to said time-delay switch means for controlling the energization thereof, and means for actuating said third switching means in response to the sensing of defective groups of cigarettes by said sensing means, wherein said motor means is connected by said first electroswitching means to operate initially at the lowest of said two different speeds, whereupon after a delay period, said time-delay switch means actuates said second electroswitching means to switch said first electroswitching means to operate said motor means at the highest of said two different speeds, and wherein said third switching means actuates said second electroswitching means to switch said first electroswitching means to again operate said motor means at said lowest speed upon the sensing of a defective group of cigarettes by said sensing means.
Claim 2
Dependent Claim

In an improved high speed cigarette packaging machine including means for providing cigarettes in groups in which said cigarettes in each group are disposed in a juxtaposed and overlying multilayered arrangement, sensing means for detecting the completion of each said group of cigarettes and the amount of tobacco within each cigarette, ejecting means for ejecting defective groups of cigarettes from the machine, and means for feeding wrapping paper for use in wrapping up said groups of cigarettes in multi-sheet casings, the improvement comprising means for automatically varying the operating speed of said machine, upon the sensing of a defective group of cigarettes, including electrical motor means for driving the machine at two different speeds; first electroswitching means for coupling between a potential source and said electrical motor means for controlling said motor means to operate at said two different speeds, second electroswitching means connected to said first electroswitching means for controlling the energization thereof, time-delay switch means and third switching means connected to said second electroswitching means for controlling the energization thereof, said first electroswitching means being connected to said time-delay switch means for controlling the energization thereof, and means for actuating said third switching means in response to the sensing of defective groups of cigarettes by said sensing means, wherein said motor means is connected by said first electroswitching means to operate initially at the lowest of said two different speeds, whereupon after a delay period, said time-delay switch means actuates said second electroswitching means to switch said first electroswitching means to operate said motor means at the highest of said two different speeds, and wherein said third switching means actuates said second electroswitching means to switch said first electroswitching means to again operate said motor means at said lowest speed upon the sensing of a defective group of cigarettes by said sensing means.
Claim 3
Dependent Claim
70 words
An improved high speed cigarette packaging machine as set forth in claim 1, in which said motor means comprises an electrical motor having two Sets of input leads for alternate connection to a potential source to operate the motor at said two different speeds, and in which said first electroswitching means comprises first and second relays each having switching contacts connected respectively to said two sets of motor input leads.
Claim 4
Dependent Claim
261 words
In an improved high speed cigarette packaging machine including means for providing cigarettes in groups, said cigarettes in each group being disposed in a juxtaposed and overlying multilayered arrangements, sensing means for detecting the completion of each said group of cigarettes and the amount of tobacco within each cigarette, ejecting means for ejecting defective groups of cigarettes from the machine, and means for feeding wrapping paper for use in wrapping up said groups of cigarettes in multi-sheet casings, the improvement comprising means for automatically varying the operating speed of said machine, upon the sensing of a defective group of cigarettes, including electrical motor means for driving the machine at two different speeds; first electroswitching means for coupling between a potential source and said electrical motor means for controlling said motor means to operate at said two different speeds, second electroswitching means connected to said first electroswitching means for controlling the energization thereof to operate said motor at the lowest of said two different speeds for a predetermined period, and for subsequently switching said first electroswitching means to operate said motor means at the highest of said two different speeds, and sensing switch means responsive to the sensing of incomplete groups of cigarettes by said sensing means and connected to said second electroswitching means to control the energization thereof, wherein said sensing switch means actuates said second electroswitching means to switch said first electroswitching means to again operate said motor means at said lowest speed for said predetermined period upon the sensing of a defective group of cigarettes by said sensing means.
Claim 5
