Fig. 2: the schematic longitudinal sectional view with the filling pipeline section of sensor device; With
Fig. 3: along the schematic sectional view of the line I-I that dissects in Fig. 2.
The specific embodiment
Below with reference to Fig. 1-3, describe in detail according to the hose bag machine for filling product of a preferred embodiment.
Fig. 1 shows the schematic sectional view of the hose bag machine 1 for filling product in accordance with a preferred embodiment of the present invention.Hose bag machine 1 comprises fills funnel 8, in described filling funnel 8 product to be filled along falling direction A a be supplied to the vertical filling tube 2 being fixed on described filling funnel.By shaping, take on 6, the packing that circulation feeds are configured as microscler packing flexible pipe 7 around filling tube 2, and described packing flexible pipe welds by means of longitudinal sealing seam in the vertical by unshowned longitudinal sealing unit here.Hose bag machine 1 comprises having the horizontal sealing unit 3 that first and second of level is sealed jaw 31,32 in addition, and described horizontal sealing unit is arranged on the end contrary with filling funnel 8 of filling tube 2.Horizontal sealing unit 3 be shaped and the packing flexible pipe 7 feeding that circulates on first seal seam at the bottom of and fall into and after flexible tube section through filling continues to move downward at a product, packing flexible pipe 7 sews the bag 20 of sealing into a sealing by means of top, wherein, also seal the end seam of next packing simultaneously.
In addition, a sensor device 5 being arranged in filling tube 2 is set, described sensor device detects the product element 11 that filling tube 2 falls that passes through of product to be filled.Sensor device 5 comprises sensor 51, described sensor 51 be arranged in the wall 20 of filling tube 2 and by circuit 14 with for controlling the control unit 4 of hose bag machine 1, be connected, described control unit is arranged in the top of the outside of filling tube 2 and the shoulder 6 that is shaped.Circuit 14 is set to put into the wall 20 of filling tube 2 here or is alternatively designed to flat cable, and described flat cable extends and do not affect the passing through of product element 11 of whereabouts on the inner side of filling tube 2.Sensor 51 is set to substantially concordant with the inwall of filling tube 2.
Sensor 51 is to emitting electromagnetic wave in a columned detection space E, described detection space is limited on a region of filling tube 2 by the first absorber element 54 and the second absorber element 55, and described the first absorber element and the second absorber element are arranged on the above and below of sensor 51 along falling direction A.
As shown in Figure 2, sensor 51 has size B on the axial direction X-X of filling tube 2, and described size B is greater than the distance C between absorber element 54 and absorber element 55.Sensor 51 is to being configured to emitting electromagnetic wave in columned detection space E, and described electromagnetic wave schematically represents by means of circular-arc line L in Fig. 2.
Electromagnetic wave is filled the inner wall area reflection that is configured to metal reflector 21 between the first absorber element 54 and the second absorber element 55 of pipe 2 and is received by sensor 51.Each the product element 11 detecting in detection space E can cause that the electromagnetic signal receiving on sensor 51 changes, and described signal changes by circuit 14 and is transmitted in Fig. 2 on invisible control unit 4.Alternatively, parasite 21 also can be configured to be divided in a circumferential direction a plurality of sections.
The first absorber element 54 and the second absorber element 55 are absorbed in the electromagnetic wave on the axial direction X-X of filling tube 20.Absorber element 54,55 be configured in the inside of filling tube 2 fully around, be particularly integrated in filling tube 2, shown in the cutaway view at the cutting line II-II place for Fig. 3 appreciiable the second absorber element 55 based on Fig. 2.Alternatively, from detection space E, starting, along the axial direction X-X of filling tube 2, a large amount of absorber element or filling tubes 2 for example with different absorption characteristics to be also set respectively correspondingly consists of multiple different material.
The advantage that therefore hose bag machine 1 for filling product according to the present invention has is: a spatially cylindric detection space E for gauge is clearly set, the detection of the remarkable improvement of the product element 11 of realizing all processes that sensitivity, horsepower output, radiation characteristic and the transmitting frequency of described detection space and sensor 51 and the diameter of filling tube 2 have nothing to do to a great extent in filling tube 2 inside at this.Therefore, can service property (quality) require significantly low sensor with low cost.In addition, radiation is only limited on the detection space E in filling tube 2.
