Fig. 9 is the side view of the being seen switch shown in Figure 7 of arrow B direction from Fig. 7; And

Figure 10 is another improved filter tip distribution system plane.

Referring to Fig. 1, a kind of pneumatic filter tip distribution system shown in the figure extends between five input pipe 2A-E and three efferent duct 4A-C.These pipes are used for pneumatically transmitting filter tip.Each input pipe 2A-E is connected on the passage 6A-E of a pneumatic distributor.Passage 6A-E is connected with filter manufacturing machine device 8A-E.Though filter manufacturing machine device 8A-E different with shown in each passage 6A-E are connected, also can be two passages or more passage be connected with identical machine.

Efferent duct 4A-C is connected on the receive path 10A-C, and its each passage is connected with a filter assembly machine device 12A-C.Path 10 A-C connects a different machine 12A-C shown in being separately, but also can two or more passage be connected with identical machine.Each distributor passage 6A-E and each receive path 10A-C can be known structures, that part of the same type of the Pegasus2000 type filter tip distribution system that for example applicant provided.

Input pipe 2A-E is connected by an array of other pipe 14 with efferent duct 4A-C, and pipe 14 has switch 16,18 so that filter tip leads between pipe.Switch 16 can make an inlet tube lead in two outlets any.Switch 18 can make one of two inlet tubes lead to an outlet.Adjusting by selector switch 16 suitably and 18 can make pipe 14 be arranged as with switch 16,18: can with input pipe 2A-E in arbitrary be connected filter tip is led among arbitrary among the efferent duct 4A-C.With similar a kind of system shown in Figure 1 in, from an expression formula 2ab-(a+b), can know necessary number of switches, wherein a and b are respectively the quantity of input and output pipe.

Figure 2 illustrates a switch 16.One input pipe 14A is connected on one movable 20, and by a connecting rod 24 and maintenance spring 26, this movable block can keep adjacency with a fixed block 22.Two efferent duct 14B and 14C are connected on the fixed block 22.(sightless in the drawings 20,22 opposite side has two connecting rods and a maintenance spring.) movable block 20 is installed on the piston rod 28, this piston rod is by a beidirectional cylinder 30 operations, and this cylinder 30 is installed on fixed block 22 and the fixed frame 34 by a trunnion seat 32.In another kind of structure, movable block 20 remains on fixed block 22 bottoms and sliding along a basic straight path between its alternate position under the effect of cylinder 30.

On position shown in Figure 2, input pipe 14A aligns with efferent duct 14B.By the work of cylinder 30, movable block 20 is removable to align with efferent duct 14C with making pipe 14A.After cylinder 30 work, the connecting rod of connecting rod 20 and maintenance spring 26 and piece 20,22 opposite sides and maintenance spring are held in place movable block 20, manage 14A like this and align with pipe 14B or 14C.Be appreciated that each piece 20,22 all comprises the hole of aliging with each pipe 14A or 14B and 14C, so that filter tip clear passage between the pipe 14A at switch 16 places and 14B or 14C.The structure of all switches 16 all is similar.Switch 18 also is a same structure, and what its difference only was to be transmitted is filter-tip by the direction difference.

Can recognize that general filter tip distribution system can provide electric connection to connect between distribution passage and receive path.For example, receive path need provide the used command signal of distributor and/or confirm just receiving filtration mouth (for example, not stopping up in the pipe that extends between each distributor and receive path).

Switch

16 and 18 not only can be used for the switch pneumatic circuit, but and while switch communication line.Fig. 3 shows a kind of system that comprises this feature.

System architecture shown in Figure 3 and working condition and shown in Figure 1 similar.Four input pipe 102A-D comprise the pipe array 114 of

switch

116 and 118 by one and are connected on three efferent duct 104A-C.In the identical mode of system shown in Figure 1, input pipe 102A-D is connected to and distributes on path 10 6A-D and the filter manufacturing machine (not shown), and efferent duct 104A-C is connected on receive path 108A-C and the filter assembly machine (not shown).

Electric connection circuit 140A-D distributes path 10 6A-D to stretch out from each, and similarly circuit 142A-C stretches out from each receive path 108A-C.These circuits are interconnected by the array of other communication line 143 and switch 144, and they can make between arbitrary route 140A-D and the arbitrary route 142A-C and be communicated with.Each route 140 and 142 itself can comprise that many parallel electric wires are to relay the interconnective a plurality of signals that respectively distribute between path 10 6 and the receive path 108.Each jettron 116,118 has a pair of electric switch 144 separately, and these switches can start to set up electrical connection between path 10 6A-D and the receive path 108A-C in respectively distributing of pneumatic connection.Each

switch

116 or 118 and 144 mechanically makes up complete to guarantee electric gentle being dynamically connected a beginning all the time.

Switch 116 shown in Fig. 5 and 6 is connected to an input pipe 114A on one of two efferent duct 114B and 114C.The structure of switch 116 and switch shown in Figure 2 16 are similar, and have a movable block 120 and fixed block 122.But in addition, electric switch 144 is fixed in fixed block 122.Movable block 120 has an arm 121, on pipe 114A shown in Figure 5 and pipe 114C positions aligning, this arm 121 acts on a switch lever 146 to close (or opening) contact 148 (Fig. 6) and to establish a connection between the electric wire relevant with 114C with pipe 114A.Thereby, switch 116 shown in Figure 5 and 144 can be as 116 ' and the 144 ' parts that identified among Fig. 3, and these switches are from distributor path 10 6D with establish a connection between the input pipe 102D that draws of pipe and the circuit that is directed to one of receive path 108A-C separately.In illustrated structure, these connections are all received on the receive path 108B.

Because the switch of being furnished with

jettron

116 or 118 as shown in Figure 3 is to 144 switches together always, promptly another always opens (vice versa) when closing for one, so switch shown in Figure 5 144 (having suitable contact) is carried out the function of two switches 144 ' shown in Figure 3.In addition, another switch 144 (not shown)s can be connected to the bottom of fixed block 122 as shown in Figure 5, and in fact moving of movable block 120 can make the communication line relevant with pipe 114C with managing 114B be connected like this.Under each situation, movable block 120 moves (managing 114A at that time aligns with pipe 114B) to its another location and can make the electrical connection disengaging of leading to the circuit relevant with managing 114C and the circuit formation relevant with managing 114B is connected.

One electric switch 144 can be connected with jettron 118 as switch 116 identical modes.

The another kind of advantage that an electronic switch 144 relevant with

jettron

116 or 118 has is to send jettron has arrived its desired operating position in fact after changing signal.Certainly, leading to electric connection circuit on the electric switch 144 relevant with

jettron

116 or 118 also can comprise usually and carry the circuit (though these signal lines are usually by switch 144 conversions) that is used to start the jettron signal.

Can recognize that in the system of Fig. 3, the electric connection between a distributor path 10 6A-D and the receive path 108A-C relates to many switch contacts, wherein any malfunctioningly can cause the system failure.Figure 4 illustrates the improvement system that wherein has only a small amount of electric switch, wherein with similar elements shown in Figure 3 adopt with Fig. 3 in similar label.In the system of Fig. 4, circuit 140A-D and 142A-C extend to formation an array, and can be interconnected by the switch 144 that establish in its intersection point place.In fact hithermost jettron 116 of each

switch

144 or 118 combinations complete (as shown in Figure 4) with it.Please note at this, with intersection cross concern associated

switch

116 and 118, for example those switches that bending section was connected by pipe 143A must be always with a pair of switch together, then be that relevant electronic switch 144 can be installed on any one of these paired switches.

Can not place switch 144 so that in fact can make the line interruption of distributing between passage and the receive path.For example, switch 144 can be arranged on control module, for example comprise in the relevant signal line of a microprocessor, and control module is in response to the state of switch and itself set up suitable connection and connect like this.

Any (or all) in the switch 16,18,116 or 118 can replace with the 216 similar rotary switches of switch shown in Fig. 7 to 9 by one.Rotary switch 216 is connected to an input pipe 214A on any one of two efferent duct 214B and 214C.Pipe 214A, 214B, 214C correspond respectively to

pipe

14A, 14B, 14C and 114A, 114B and 114C, and can constitute with about managing the part of 14 and 114 the similar pipe array of described pipe array.

Efferent duct

214B, 214C are installed to by suitable connector on the surface of a fixed head 222, and this fixed head comprises and aligns with efferent duct and from a plurality of borings of this plate through a relative parallel surfaces.One portable plate 220 have a correspondence, near the described apparent surface's of plate 222 parallel surfaces.The rotation starter 230 with on identical that side of

pipe

214B, 214C that is arranged on plate 222 has a driving shaft 231, and this passes hole on the plate 222 rotationally and is fixed on the portable plate at 233 places.

Input pipe 214A is installed on the portable plate 220 and with a hole of passing this plate by a suitable connector and aligns.The axis equidistant placement of the Kong Douyu axle 231 in hole in the plate 220 and the plate 222.Hole on the portable plate 220 is being the elastic sealing device that O shape is enclosed 235 forms having at least near plate 222 those ends in a groove of hole periphery, the airtight sealing of formation one between the hole on

plate

220 and 222 when align in the hole on

plate

220 and 222 like this.Plate 222 portable electricity are near switch 244.

During work, can operate double-action type rotation starter 230 so that member 220 turns between 45 ° pipe 214A and the 214B positions aligning at illustrated

pipe

214A and 214C positions aligning and clockwise direction as shown in Figure 8 back and forth pivots.Input pipe 214A can make so that be connected to that end on the plate 220 moves and other end (not shown) is fixed with flexible material, for example plastic material.Pipe 14A or 114A also can materials similar make.

But the feature that is arranged to one or more features of check-out console 220 or is brought by plate 220, can be any function that can carry out switch 144 near the electric switch 244 of switch.In addition, these switches can be replenished to carry out the part of these functions at least by the contact switch (not shown).

Aforesaid, switch 216 is between input pipe 214A and two

efferent duct

214B, 214C; When

pipe

214B, 214C are input pipe and pipe 214A when being efferent duct, this switch is well-adapted equally.Under latter event, preferably portable plate 220 has the through hole on each side that is positioned at pipe 214A, and when pipe 214A alignd with pipe 214B, pipe 214C alignd with one of these holes like this, and when pipe 214A alignd with pipe 214C, pipe 214B alignd with another hole.For this structure, if filter tip not with input pipe that efferent duct 214A aligns in when transmitting (normally because fault), withdraw from the corresponding aperture on those filter tip slave plates 220, rather than rest in the input pipe and may cause backlog.

In the Pneumatic pipe conversion, the suitable connection of the conversion of machinery connects can guarantee that after path changes the filter tip that is subjected to correct control between required distribution passage and receive path transmits.One control system can be managed the input and output configuration of Pneumatic pipe by the collected continuous monitoring information of equipment that connects from system.Usually, this equipment comprises one or more filter manufacturing machine devices, and this machine connects with a filter tip receptacle (for example, Molins Polar) separately; The one multi-path distributor that is connected with each filter manufacturing machine device/filter tip receptacle; One or more duct receivers in one or more filter assembly machine devices and each filter assembly machine.In such system, for multiple devices, the handled information of control system (control system will realize consequential connection conversion on this basis) is as described below:

Filter manufacturing machine device: address (I.D.)

The filter tip type

Instruction (ON/OFF)

Filter assembly machine device: address (I.D.)

The filter tip type

Operating speed

Control system also can have other function.For example, pneumatic filter tip distribution system is responsive, the i.e. higher circuit air pressure of long tube operation needs for the air pressure of circuit.This system can be arranged to calculate in the new distance between distributor and the receiver after the connection variation automatically line pressure is reset to the value that adapts to this distance.But by the electronic control governor setting pressure in the distributor.Can calculate this distance from the information of length of tube between the relevant position of the switch that control system provided and switch.

With determine that distance combine or individually, this control system can check after the switch connection whether realized proper configuration.Thereby, can carry single filter tip and write down it to have arrived receiver.If know the distance of leaving receiver, system can determine filter-tip average speed and adjust line pressure again to compensate any abnormal conditions.The single filter tip that is transmitted can discharge by the outlet of one on the receiver, and that is for example disclosed in the british patent specification 2272414 is such.

As determining that according to input information a kind of of distance replenishes or the replacement form, can transmit an acoustic impluse and this pulse of record in receiver along pipe.Passing time can be used for determining tube length.The information of blocking in the pipe also can be fed back by one similar system.By surveying echo, can determine to block the position of generation.In addition/or, with a sound or a test-filtration mouth, connect and detect new pipe path by conversion and can obtain an estimation: this can determine to block be before the switch position or after.By at key place one or more flows or pressure detector being set, also can show congestion situations along tube length.

The information relevant with the input and output product variations can be sent in a PC or other processor able to programme, is which kind of product with what be recorded in positively that moment carried to each filter assembly machine.These characteristics can be followed the tracks of bulk article.

The system of Fig. 1 also can be communicated with in conjunction with described any of reference Fig. 3-5 and connect and control system.

In system shown in Figure 10, three the pneumatic allocation units C1, C2, the C3 that have five passage S, D1, D2, D3 and D4 separately are connected on six filter assembly machine P1-P6 by Pneumatic pipe 60, and each assembly machine has the receiving element of band two passes.These allocation units C1-C3 is connected to (not shown) on the filter manufacturing machine device separately.The Pneumatic pipe 60 that leads to each machine P1-P6 only illustrates that is used for machine P1.Receive path among each machine P1-P6 is connected to the distribution passage on the different units.Thereby when one of unit C1-C3 breaks down when breaking down (or its relevant filter manufacturing machine device), each machine P1-P6 should continue receiving filtration mouth from least one pipe 60 that is attached thereto.

Distribute the connection between passage and the machine P1-P6 as follows:

Machine passage 1 interface channel 2 connects

P1 C1D1 C2D1

P2 C1D2 C2D2

P3 C1D3 C3D1

P4 C2D3 C3D2

P5 C1D4 C3D3

P6 C2D4 C3D4

In this form, C1D1 represents the distribution passage D1 among the unit C1, by that analogy.

Each unit C1-C3 constitutes a hopper, and this hopper can receive the filter tip of comfortable relevant filter manufacturing machine device, and they are delivered in five distribution passages of unit.These unit can be the MolinsPegasus dispenser units.Independent binary channels receiving element R1-R3 is connected respectively on the unit C1-C3, all is transported in the hopper of each unit C1, C2 or C3 by the filter tip that receiving element received like this.Receiving element R1-R3 can be Molins Pegasus receiving element (and can be identical with the receiving element of machine P1-P6 institute combination).

Distribution passage S among the unit C1 is standby, and is not connected on the arbitrary pipe that directly extends to one of machine P1-P6.It is connected on the input pipe 62A of the switch 64A with three

efferent duct

66A, 68A and 70A.Switch 64A roughly with switch 15 shown in Fig. 2 and 5 and 116 or switch 216 structures of Fig. 7 similar, just it has three operating positions.Pipe 66A is connected respectively on the receive path of receiving element R2 relevant with C3 with other dispenser unit C2 and R3 with 68A.Pipe 70A is connected on the passage of a triple channel receiving element 72 that connects (also being a Molins Pegasus unit), fills out in the machine of putting 74 and filter tip is transported to a pallet.The alternate channel S of unit C2 and C3 manages 66B, 68B, 70B and 66C, 68C, 70C with unit C1 similar connected mode to be connected with 62C, switch 64B with 64C and other by each unit 62B.

The system of Figure 10 can make the spare capacity of the filter manufacturing machine device relevant with arbitrary unit C1, C2 or C3 be used for replenishing the supply in other unit.In addition, spare capacity is used for pallet and fills out the machine of putting 74, is fed forward to another allocation units or filter assembly machine with the filter tip in the pallet.Because the connection between unit C1, C2 and the C3, the filter tip that is transported to these unit (for example from the filter manufacturing machine device) must be a same-type.On the contrary, in Fig. 1,3 and 4 system, can carry dissimilar filter tips, if they in fact with the pipe compatibility, and can guarantee that receiver receives only the correct product relevant with relevant filter assembly machine device.Thereby when transmitting dissimilar filter tip in these systems shown in Fig. 1,3 or 4, must interrupt some switch and connect (can not mix) to guarantee dissimilar filter tips.

The system of Figure 10 can have suitable connection and connect, and they are changed with the described same way as of the system of reference Fig. 3-5 by

switch

64A, 64B and 64C.
