The US 邦纳 engineering firm, founded in 1966,
was in the world the biggest photoelectricity switch, the survey
examination and one of security product specialized manufacturers,
relied on the leading designed capacity, the splendid manufacturing
capacity and 15,000 many kinds of products, provided the rich product
and the solution for the different user. In economical rapid
development today, China's thing class stores in a storehouse the
profession although starts late, but develops extremely rapidly, the
scale also gradually expands, the customer stores in a storehouse the
equipment to the thing class the automaticity request also more and
more high, both wants high speed reliable, and wants the economy to be
practical, this gave the equipment manufacture merchant to propose the
difficult problem. At present has the difficulty which two kinds
examines, first is examines the packing container the three
dimensional external dimensions, before continuously all does not have
one reliable economical the solution. The customer on-line
requests to examine the packing container the length, the width, is
high, then delivers the data on the position machine to carry on
processing, judges the packing container the size, again actuates the
implementing agency divergence different size the packing container,
achieved the entire automatic cargo minute examines goal; Second
is the automatic hay stacker localization, the cargo delivers on the
hay stacker in the automated multi-layered storehouse by the conveyer
belt, then sends out the instruction from the host system to the hay
stacker control system, informs it the storehouse position which
delivers the cargo assigns, this time the system must confirm the hay
stacker moves the position determined the crosswise storehouse
position (like chart 1 shows), before generally has two kind of
solutions, one is the use approaches the switch or the limit switch in
each storehouse position examination hay stacker whether arrives, this
law simple when matches the line complex also cannot really monitors
the hay stacker the position, the control procedure is complex.
Two, uses the encoder indirectly to survey the hay stacker the
position, this law connection is more complex also needs the procedure
computation to be able to obtain the indirect position data extremely
to trouble. Therefore above two methods not extremely are all
ideal. In view of these two difficult problems, 邦纳 the
company develops two kind of new surveys products, one kind is the LT7
series laser long-distance range position transmitter, its survey
principle is the echo analytic method, sends out the time difference
as well as the laser wave length using the pulse of laser light which
and returns calculates was measured the object the position, he has
two kind of surveys patterns, directly reflects the type and the
reflection beat, the survey is away from respectively is 10m and 250m,
the resolution reaches 2mm, has the standard the simulation quantity
output and the switch quantity output as well as the serial
communication RS422/SSI output, the pressed key hypothesis examination
scope convenience is reliable, has the extremely high natural price
ratio. This kind of sensor may use in to survey the packing
container the altitude, the width (like chart 2, 3 types) as well as
the hay stacker localization (like chart 1 shows). When survey
packing container width uses two LT7 separately to survey the packing
container two sides distances, then through on position machine
computation width, when bone according to the conveyer belt width and
the packing container volume decided uses or many only LT7 carries on
the survey. The hay stacker localization is uses the reflection
beat LT7, fixes the baffle plate in the movement hay stacker side, LT3
fixes in the baffle plate opposite, like this may when really obtains
the hay stacker the position signal. Moreover one kind of new
product is the MINI-ARRAY series high resolution survey light curtain,
this series product has 2.5mm the resolution, the correlation distance
reaches 1.8m, the bone from 150mm to 2m, and may choose the different
output form the controller. In surveys the packing container
three dimensional size the application Chinese Communist Party to use
three set of MINI-ARRAY survey light curtain separately to survey the
packing container the length, the width, is high (like chart 4 to
show), then delivers the data in the controller, the controller basis
different scanning analysis pattern, calculates the corresponding
simulation quantity signal (4~20mA or 0~10V) and outputs on the
position machine, on position machine basis procedure control
implementing agency movement; Simultaneously the MINI-ARRAY
controller also has the switch quantity output, may define as the
different function, if the cargo superelevation reports to the police
or the system failure reports to the police. This set of
systematic response time is highest may achieve 1.8ms, completely is
suitable to the high speed thing flows the production line. The
LT7 long-distance range laser position transmitter and high resolution
survey light curtain MINI-ARRAY not only may use in the thing to flow
the production line, but also may use in the overhead travelling crane
to guard against hits; Dip control; The postal parcel
minute examines; The volume material corrects an error;
The highway charge stands the vehicles count; Log outer
diameter survey; The steel plate passes the hole examination;
The object to the medium each kind of different application, in
brief, the BANNER Corporation's these two kind of new products has the
widespread application prospect in the automated domain, it not only
performance reliable, measuring accuracy high, the speed of response
is quick, more importantly it was allowed to solve you before is
unable examination difficult problem which solved. The US 邦纳
engineering firm collection more than 30 years photoelectricity
product development and the application experience, provides more
sensors for you and the more solution. |
