Pressurizing chamber 208 is fluidly connected with check-valves 206 by check-valves outlet 256 and pressurizing chamber import 258.In order to immediately
Activation, pressurizing chamber 208 maintains the pressure in activator 200, in order to pump 204 need not work in total pressure or all the period of time, because pump
204 must edge up to operating pressure when opening and closing or gradually lower from operating pressure.On the contrary, pressurizing chamber 208 is maintained
Interior pressure fluid can use as required.
Fig. 5 depicts an embodiment of pressurizing chamber 208.In order to compact, pressurizing chamber 208 substantially rectangle and orient
In upright position.Pressurizing chamber 208 in this embodiment is configurable at lower containment fluid displacement, keeps variable on top
Gas volume.Pressurizing chamber import 258 is arranged in the side of pressurizing chamber 208.Pressurizing chamber outlet 260 be arranged in pressurizing chamber 208 with
The side that pressurizing chamber import 258 is relative.Pressurizing chamber outlet 260 is further arranged to be in the horizontal plane lower than pressurizing chamber import 258,
To promote that fluid flows out pressurizing chamber 208.Fluid sensor 262 can be arranged in above pressurizing chamber outlet 260, to detect fluid
Whether volume is less than certain level.Air cock 264 is arranged in the top side of pressurizing chamber 208, it is possible to automatically open up, to discharge system
Interior excessive gas volume.
When the liquid valve 210 of applicator 212 upstream cuts out, the fluid being pumped into pressurizing chamber 208 increases in pressurizing chamber 208
Add fluid displacement, thus improve the gas pressure in pressurizing chamber 208 by compressed gas volume.Once liquid valve 210 is opened,
The gas volume of pressurization presses to all surface to recover its balancing volume, and the fluid being forced out pressurizing chamber outlet 260 flows to be coated with
Applicator 212.As the system pressure in fruit caving 208 and/or liquid level become less than predetermined value, control system 214 opens pump 204 with again
Secondary filling chamber 208.
The alternative embodiment of pressurizing chamber can include one section of pipe or other structure with elastic wall.Along with pressure is at pipe
Interior foundation, the elasticity of wall makes pipe be stretched to bigger diameter.Once valve is opened, and is contracted to its balance diameter by pipe and drives
Fluid.In another embodiment, pressurizing chamber includes vertical fluid column, and it is enhanced when fluid increases and liquid valve is cut out,
Thus increase the potential energy that fluid column stores.When liquid valve is opened, the potential energy of increase provides sufficient flow to apply with interim operation
Device.
Liquid valve 210 in the embodiment described is by liquid valve import 266 and pressurizing chamber outlet 260 and pressurizing chamber
208 fluidly connect.Liquid valve 210 adjusts fluid and is delivered to the time of applicator 212 from pressurizing chamber 208.In one embodiment,
Liquid valve 210 is normally closed electromagnetic valve, but any valve that can control fluid flowing can be used (to be such as designed to selectively
Block the folder valve of one section of flexible pipe).In using the embodiment of activator 200 of liquid valve 210, the state of liquid valve 210 (is opened
Or close) whether regulation activator 200 run (that is, valve runs when opening, and does not runs when valve cuts out).
Applicator 212 is fluidly connected with liquid valve 210 by liquid valve outlet 268 and applicator import 270.A reality
Executing in example, applicator 212 is substantially cylinder, with a series of little, evenly spaced taps 272 (such as, jet pipe).
Applicator 212 can be substantially any shape with at least one tap 272 pointing to activated positions, but it is permissible
There is the cross-sectional area of taper or the hole dimension of change, in order to produce uniform on its adhesive phase when that passes through when label
Spray pattern.Applicator 212 is disposed proximate to the activated positions in tag path, herein label will by and sprayed by solvent.
By obtaining the flowing (that is, the liquid jet) that the liquid of relatively large and low volume flows and they become faster, more concentrates, row
Portal and 272 use as nozzle.Tap 272 is placed in proximity in activated positions, sufficiently close together concentrates and accurate to produce
The liquid jet, but enough remote to avoid contacting with label entries, and jet mode is formed.Alternate embodiment uses single
The activating solvent of pressurization is ejected into activated positions by hole nozzle, it is common that flat fan pattern.
Tap 272 is the parts of final coutroi velocity, and it specifies the activating solvent thick coating of the needs on label subsequently
Degree.The applying of this solvent coating thickness is the important step of the adhesive phase of activation tag.Solvent coating thickness can be by following
Formula determines:
Thickness (mils)=[flow velocity (mL/min) * 0.06102in3/ mL*1000mils/in]/[label speed (in/
Sec) * tag width (in) * 60sec/min]
As shown in this formula, thickness is directly affected by flow velocity, label speed and tag width.Label speed and tag width
Both are determined by other equipment of label machine or activator upstream.Each in these variablees can be single for each
Only printer, label sprayer etc. are fixing, or they can change.Assume the configuration determined, so stay flow velocity to make
For retaining variable, to obtain the coating layer thickness needed.We can further from the point of view of flow velocity, utilize following equation to pass through to make coating
Nozzle diameter in the manifold of device 212 associates with flow velocity with number of nozzle:
FlowNewly=flowOld* (# nozzleNewly/ # nozzleOld) * (diameter2 Newly/ diameter2 Old)
Known configurations (being labeled as " old ") and Utopian prediction (being labeled as " newly ") are associated by this formula.Utilize with
The experimental data that the nozzle manifold of 20 a diameter of nozzles of 42 microns is collected shows, nozzle produces the flow velocity of 9.733mL/min.
From this information, the formula of new expection flow velocity is:
FlowNewly(mL/min)=9.733 (mL/min)/[20*422(μ)] * # nozzleNewly* diameter2 Newly(μ)
This formula supposes that internal system pressure is constant.But, system pressure and nozzle area have dynamic relationship
(that is, if nozzle area increases, and owing to having more loss etc. by bigger nozzle, therefore pressure reduces).But these public affairs
Formula still provides the approximation that some are useful.
Based on above-mentioned formula, select series of spray nozzles so that flow velocity, pressure, jet quality etc. are carried out experiment test.To the greatest extent
Pipe solvent thickness generally between about 0.3 to 0.5mils, this scope can extend to about 0.15 to 0.75mils it
Between, the most wide in range.Coating layer thickness affects the binding agent quality of activation tag, and can change to be suitable at gauffer cardboard or
Execute the different application requirement on other base material tagged.This scope can further expand to meet gauffer cardboard shipping label
The outer label requirements in field, such as, the label being used on vial.
