Description
2266598 Apparatus and method for feeding and weighing textile fibres.
The invention relates to an apparatus and method for feeding and weighing textile fibres, especially cotton and synthetic fibres.
In a known apparatus there are two series-arranged filling shafts above a weighing container. The shafts are charged with fibre material, the upper filling shaft being closed at its lower end by two controllable takeoff rollers and the lower filling shaft being closed at its lower end by at least one controllable shut-off flap. The weighing container is first pre-filled in high-speed operation (pre-filling) and then topped up with flocks in low-speed operation (topping-up).
In the case of the known apparatus, when the weight programmed for the pre-filling operation has been reached, low-speed operation begins and the amount by which the weight in the weighing container is short is made up with flocks. As soon as the programmed desired weight has been reached, the shut-off flaps are closed and the transport of material is stopped so that no more flocks fall into the weighing container. After a short stabilising period, the actual charge weight is checked again. Discharge then takes place, during which the transport of material takes place for a short calculated time and a reserve of material forms above the shut-off flaps. When the shut-off flaps open again after the weighing container has been emptied, the reserve of material falls into the weighing container and reduces the time required for the next filling operation.
It is an object of the present invention to provide an apparatus and method which permits a greater produc tion per unit of time.
According to the invention there is provided an apparatus for feeding and weighing textile fibres, the apparatus comprising a weighing container, a first filling shaft for storing fibre material to be fed into the weighing container, means for controlling flow of fibre from the first filling shaft to the weighing container, a second filling shaft for storing fibre material to be fed into the weighing container, means for controlling flow of fibre from the second filling shaft to the weighing container, means for charging the first and second filling shafts with fibre material, the feeds of fibre from the first and second filling shafts into the weighing container being in parallel to one another, the arrangement being such that the rate of feeding of fibre from the first filling shaft can be substantially greater than the rate of feeding of fibre from the second filling shaft and the first filling shaft can be charged with fibre material, while fibre is being fed from the second filling shaft to the weighing container.
According to the invention there is also provided an apparatus for feeding and weighing textile fibres, especially cotton and synthetic fibres (weigh feeder), in which two series-arranged filling shafts are present above a weighing container and are charged with fibre material, the upper filling shaft being closed at its lower end by two controllable take-off rollers and the lower filling shaft being closed at its lower end by at least one controllable shut-off flap, and in which the weighing container is first pre-filled in high-speed operation (pre-filling) and then topped up with flocks in low-speed operation (topping-up), characterised in that at least one further filling shaft that is closed at its lower end by controllable take-off rollers is present above the weighing container and adjacent to the two is series-arranged filling shafts, the series-arranged filling shafts are provided for pre-filling and the further filling shaft is provided for topping up the weighing container and, during the filling of the weighing container from the further filling shaft (topping-up), a series-arranged filling shaft is filled simultanously with fibre material.
According to the invention, a reserve of material is built up in a filling shaft in high-speed operation and the fine-filling of the weighing container from a filling shaft takes place simultaneously (in parallel) in lowspeed operation. In that manner operating time is saved by two simultaneous steps, so that a greater production per unit of time is made possible.
During the filling of the weighing container from the series-arranged filling shafts (pre-filling), the further filling shaft is expediently filled with fibre material simultaneously. The upper filling shaft of the series-arranged filling shafts and the further filling shaft are advantageously filled simultaneously one after the other. Preferably, the upper filling shaft and the lower filling shaft are associated with one filling level sensor each, for example a photoelectric cell. Two filling level sensors, for example photoelectric cells, arranged one above the other are preferably associated with the further filling shaft. The upper filling shaft is expediently terminated at its upper end by a switch- is over flap. The photoelectric cells advantageously control the drive devices for feeding the streams of f ibre material to the weighing container. When the photo-electric cell is passed, the switch-over flap is preferably switched over. When the photoelectric cell is passed, the drive device for the take-off rollers is preferably stopped. The photoelectric cell expediently controls the drive device for the take- off rollers at the upper filling shaft in such a manner that, when the photoelectric cell is passed, the drive device is caused to operate at high speed. The photoelectric cells advantageously control the drive device for the take-off rollers at the further filling shaft in such a manner that the drive device is caused to operate at low speed.
A fast-running opener roller is preferably arranged below each pair of controllable slow-running take-off rollers.
Preferably the weighing container has two controllable and pivotable base flaps. The photoelectric cells, the drive devices, for example electric motors, for the take off rollers, the drive device for the switch-over flap, the drive device for the shut-off flap and the drive device for the base flaps are expediently connected to a common electronic control device.
According to the invention there is also provided a method of feeding and weighing textile fibres, the method comprising the following steps:
a) feeding fibre material into a weigh container at is a relatively fast rate from a first filling shaft, b) feeding fibre material into the weighing con tainer at a relatively slow rate from a second filling shaft until the desired total amount of fibre material is in the weighing container, and at the same time refilling the first filling shaft, and c) emptying the fibre material from the weighing container.
By way of example an embodiment of the invention will now be described with reference to the accompanying drawings, of which:
Fig. 1 is a diagrammatic sectional side view of an apparatus for feeding and weighing textile fibres, 5 Figs. 2a and 2b show the alternate filling of the adjacent filling shafts (fibre material charging) by a material feeding device, and Figs. 3a to 3c show the pre-filling and fine-filling of the weighing container.
Figure 1 shows a weigh feeder 1 in which two seriesarranged filling shafts 3, 4 are present above a weighing container 2 and are charged with fibre material (see Figures 2a, 2b and 3a to 3c). The upper filling shaft 3 is closed at its lower end by two controllable slowrunning take-off rollers 6a, 6b downstream of which a fast-running opener roller 7 is arranged. Also present above the weighing container 2 and adjacent to the two series-arranged filling shafts 3, 4 is a further filling shaft 5 which is closed at its lower end by two controllable slow-running take-of f rollers 8a, 8b downstream of which a fast-running opener roller 9 is arranged. A condenser 10 having a rotating perforated drum (not shown) is arranged above the filling shafts 3 and 5 for charging the shafts. A conveyer belt 11 is provided below - 7 the weighing container 2.
Photoelectric cells 12 and 13 are associated, as filling level sensors, with the upper filling shaft 3 and the lower filling shaft 4, respectively. Two photoelec- tric cells 14 and 15 arranged one above the other are associated with the further filling shaft 5. The upper filling shaft 3 is closed at its upper end by a controllable switch-over flap 16 which is rotatable about a pivot bearing 17 in the direction of arrows A, B. The lower filling shaft 4 is closed at its lower end by a controllable shut-off flap 18 which is rotatable about a pivot bearing 19 in the direction of arrows C, D. The weighing container 2 is closed at its lower end by two base flaps 20a, 20b that are pivotable in the direction of arrows E.'/ Ell, F', V'. Stationary guide elements 21 and 22 for the fibre material, which at the same time co-operate with the shut-off flap 18 in a sealing manner, are present at the lower ends of the filling shafts 4 and 5, respectively. Controllable drive motors 23 and 24, for example direct current motors, are associated with the take-off roller pairs 6a, 6b and 8a, 8b, respectively.
In use, the weighing container 2 is pre-filled at high-speed (prefilling) and topped up to its final load at low-speed (topping-up). The series-arranged filling shafts 3 and 4 are provided for pre-filling and the further shaft 5 for topping up the weighing container 2. While the weighing container 2 is being filled from the further shaft 5 (topping-up) the lower filling shaft 4 is being f illed simultaneously with f ibre material, that is to say, a reserve of material is already being formed in the filling shaft 4 for the following pre-filling of the weighing container 2.
The photoelectric cells 12, 13, 14, 15, the drive devices 23, 24, for example electric motors for the takeoff rollers 6a, 6b; 8a, 8b, the drive device for the switch-over flap 16, the drive device for the shut-off flap 18 and the drive device for the base flaps 20a, 20b are connected to a common electronic control device (not shown).
The fibre material is fed to the condenser 10, from a hopper feeder (not shown) or a bale opener (not shown).
is Referring now to Figure 2a, the fibre material is thrown by the condenser 10 into the upper filling shaft 3 as shown by arrow G. When the photoelectric cell 12 goes into the dark, the filling shaft 5 is filled with fibre material from the condenser as shown in Figure 2b by arrow H by switching the switch-over flap 16 to the position shown in Figure 2b. At that stage the drive device 23 for the roller 6a and 6b can be caused to operate. Then, after again switching over the switch-over flap 16, the filling shaft 3 is filled again according to Figure 2a. This procedure (charging the filling shafts 3 and 5 alternately with material) is repeated independently of the following weighing operation. The shaft 5 9 can be kept filled to a level substantially between the photoelectric cells 14 and 15 by the control device and when the photoelectric cell 14 goes into the dark, the drive device 24 for the rollers 8a, 8b can be caused to operate at relatively low speed.
Referring now to Figure 3a, the filling shaft 4 is filled (arrow I) by the take-off rollers 6a, 6b and the downstream opener roller 7 in approximately from 3 to 5 seconds (adjustable by means of gear motor 23, for example direct current motor). As the shaft 4 becomes full the photoelectric cell 13 goes into the dark and the transport of material into the shaft 4 (caused by the rotation of the take-off rollers 6a, 6b) is stopped.
Then, as shown in Figure 3b, the shut-off flap 18 opens and the weighing container 2 (the scales) is filled (arrow K) with the contents of the shaft 4. Then, as shown in Figure 3c, the shut-off flap 18 closes and the transport of material into the shaft 4 (take-off rollers 6a, 6b) starts. The filling shaft 4 is filled again (arrow L).
Two operations now take place (as shown in Figure 3c) at the same time: 1) filling of the filling shaft 4 (as already mentioned), and 2) fine-filling of the weighing container 2 from the shaft 5 by the take- off rollers 8a, 8b and opener roller 9 for approximately from 3 to 5 seconds (arrow M), until the desired weight of fibre material is present in the container 2. A weighing device (not shown) is associated with the weighing container and is connected to the common electronic control device referred to above.
After reaching the desired weight in the weighing container 2, the base flaps 20a, 20b of the weighing container 2 open and the weighed fibre material falls onto the conveyor belt 11. The base flaps 20a, 20b then shut again. The operation (opening the flaps, discharg ing, closing the flaps) can be repeated up to 12 times per minute.
The timing of the various operations starting f rom a condition in which the shafts 3, 4 and 5 are all filled can be as follows:
a) Start of first weighing operation b) 1 see. Shut-off flap 18 opens and closes (the material f rom the material shaf t 4 - approximately 90 % of the total charge - falls into the weighing container 2 arranged below).
c) 3 sec. Material shaft 4 is pre-filled.
d) 3 sec. The remaining 10 % of the total charge is fed via material shaft 5 (fine-filling) to the weighing container 2.
e) 1 see. Weighing container 2 opens and closes; the 5 material falls onto the conveyor belt 11 arranged below. f) Start of second weighing operation.
In the weighing operation described above steps (c) and (d) are simultaneous and the other steps are sequen tial. A single complete weighing operation lasts five seconds allowing there to be 12 weighing operations per minute.
In the case of a weighing container with an inside width of the frame of 1200 mm and a capacity of 1.2 kg, that would mean, theoretically, 864 kg/h, and in the case of an inside width of the frame of 1600 mm and a capacity of 1.6 kg, 1,152 kg/h.
The advantages of the apparatus embodying the invention reside in the use of a condenser 10 for supply, high production of the order of 1000 kg/h per weigh feeder, high-speed operation for pre-filling and low speed operation for fine-filling simultaneously (in parallel) with the filling of another shaft, controlled material reserve by adjustable photoelectric cell (materi a 1 -dependent), pre-filling approximately from 80 to 90 % of the total weight, avoidance of alternating current drive motors, high material reserve and inexpensive production.
The possible production rate of 2500 kg/h (in the case of three weigh feeders 1) can, owing to the high degree of efficiency of the weigh feeder 1, which provides a more nearly continuous supply of fibre, be readily processed (using a faster running conveyor belt 11) by the flock mixer (which may be the conveyor belt 10 11).
