Abstract
Abstract A fully automatic labeling system having a sending-in conveyor, a weighing conveyor and a sticking conveyor which have their operations controlled independently of one another. This invention controls the operations of the conyeyors so that the conveyors may be driven in only necessary states and that weighing and label sticking may be reliably and most efficiently performed even during transfer of a commodity between the conveyors. In both a print fixing operation and a two-stage print mode for a label, transportation intervals of the commodities can automatically have necessary time differences.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
146 words
A conveyor control apparatus in a fully-automatic labeling system comprising: a sending-in conveyor, a weighing conveyor and a sticking conveyor which have their operations controlled independently of one another and which are disposed in alignment with one another, sensors which are disposed in proximity to the respective conveyors and which detect the existence of a commodity, short-time timers which control outputs from these sensors, an intermittent timer which controls the operations of said weighing conveyor and said sticking conveyor, depending upon whether or not the sensor of said sending-in conveyor has detected the commodity within a predetermined time, a load cell, said weighing conveyor being a load of said load cell, a printer which prints data based on a signal from said load cell or preset data on a label, and a sticking machine which sticks the printed label to the commodity on said sticking conveyor.
Claim 2
Dependent Claim
146 words
A conveyor control apparatus in a fully-automatic labeling system comprising: a sending-in conveyor, a weighing conveyor and a sticking conveyor which have their operations controlled independently of one another and which are disposed in alignment with one another, sensors which are disposed in proximity to the respective conveyors and which detect the existence of a commodity, short-time timers which control outputs from these sensors, an intermittent timer which controls the operations of said weighing conveyor and said sticking conveyor, depending upon whether or not the sensor of said sending-in conveyor has detected the commodity within a predetermined time, a load cell, said weighing conveyor being a load of said load cell, a printer which prints data based on a signal from said load cell or preset data on a label, and a sticking machine which sticks the printed label to the commodity on said sticking conveyor.
Claim 3
Dependent Claim
92 words
The conveyor control apparatus in a fully-automatic labeling system as set forth in claim 1, wherein when the commodity has been detected by said sensor disposed in proximity to said sending-in conveyor, the predetermined time is set by said intermittent timer upon the detection, and when said sensor does not execute a new commodity detection in said predetermined time, said weighing conveyor and said sticking conveyor are stopped, while when it executes the new commodity detection in said predetermined time, the operations of said weighing conveyor and said sticking conveyor are continued.
Claim 4
Dependent Claim
97 words
The conveyor control apparatus in a fully-automatic labeling system as set forth in claim 1, wherein said sending-in conveyor is stopped upon the commodity detection by said sensor of said sending-in conveyor, and said sending-in conveyor is started by a combination of the short-time timer and the output of said load cell which starts upon the detection of the already-fed commodity by said sensor of said weighing conveyor, whereby the automatic weighing of the commodity is performed under a condition in which a period of time, during which no commodity exists on said weighing conveyor, is shortened.
Claim 5
Dependent Claim
91 words
The conveyor control apparatus in a fully-automatic labeling system as set forth in claim 1, wherein, in a print fixing operation in which a print content is fixed, said sending-in conveyor is stopped upon the commodity detection of said sensor of said sending-in conveyor and is started by a combination of the short-time timer and the output of said load cell which starts upon the detection of the already-fed commodity by said sensor of said weighing conveyor, thereby to match timings of a commodity transportation interval and a label issue interval.
Claim 6
Dependent Claim
66 words
The conveyor control apparatus in a fully-automatic labeling system as set forth in claim 1, wherein, when the print for the label is of one stage, a transportation speed of said sticking conveyor is set so that the commodity may reach a label sticking position after a fixed time, preset as is necessary from the detection of the commodity by said sensor of said sticking conveyor.
Claim 7
Dependent Claim
61 words
The conveyor control apparatus in a fully-automatic labeling system as set forth in claim 1, wherein, when the print for the label is of two stages, said sticking conveyor is temporarily stopped from the detection of the commodity by said sensor of said sticking conveyor to completion for preparation for the label sticking, thereby to permit print time to be long.
Claim 8
Dependent Claim
48 words
The conveyor control apparatus in a fully-automatic labeling system as set forth in claim 1 or 6, wherein, when the print for the label is of two stages, a start timing of said sending-in conveyor is delayed with respect to a start timing in a one-stage print mode.
Claim 9
Dependent Claim
28 words
The conveyor control apparatus in a fully-automatic labeling system as set forth in claim 1, wherein said load cell continues to operate even when no commodity is flowing.
