Definitions
- a storage bin which serves as a link between two machines in a cigarette making factory and which moreover acts as a buffer between the two machines.
- the bin has at least three end to end conveyors forming its base.
- Control means are provided to actuate and deactuate the various conveyors to cause articles fed into one end of the bin to form heaps which are then transported to the other end of the bin.
- the control means are individually responsive to the level of articles at the feed and discharge ends of the bin and the start of the third and subsequent conveyors from the feed end of the bin.
- This invention relates to storage bins.
- an essential feature of the link is that it must receive articles in the way that the delivering machine delivers them and presents them to the receiving machine in a fashion best suited to the receiving machine.
- An object of the invention is to provide a storage bin which can serve as such a link and which also serve as a buffer between the two machines.
- a storage bin according to the invention consists of:
- first sensing means for sensing the level of goods adjacent the fixed wall
- second sensing means for sensing the level of good at the discharge zone
- third sensing means for sensing the presence of goods at a predetermined level over the start of the third band, i.e. the end of the third band nearest the fixed wall;
- intermediate sensing means similar to the third sensing means at the start of each band after the third;
- FIGS. 1, 2 and 3 are schematic sections through the storage bin of the invention, illustrating its operation.
- FIG. 4 is a schematic diagram illustrating a control circuit according to the present invention.
- the bin has a fixed rear wall 4 inclined at the angle or repose of the goods being' handled.
- a discharge hopper 12 from which conveyor belts 13 extract the goods being handled.
- a feed conveyor 10 feeds goods into the bin.
- the goods are rod-shaped articles the orientation of which have to be maintained.
- a bridge 2 from which there hangs a series of curtains 3 according to the teachings of the complete specification of Republic of South Africa Pat. No. 66/615.
- sensing device C At a predetermined level over the start of the belt 7 there is a sensing device C which senses the presence of goods at that level. Similar devices D are at the starts of the belts 8 and 9.
- the control means causes all the belts excepting the belt 5 to move. This causes a valley to be formed between the belts 5 and 6 so that the mass of goods is divided into two parts (FIG. 3).
- the forward part keeps on moving until a signal from the device B that the maximum level has been reached causes the belts 6 to 9 to stop.
- the rearward part adjacent the wall 4 remains stationary unless a signal from the device A starts belts 5 and 6.
- the device C determines when a heap has to move forward. However, it also controls the belt 7 to inhibit it from moving when the device B signals that the upper level has been reached and the device C determines that sufficient material is in front of it. Likewise the devices D control the belts 3 and 9 to inhibit them from moving when suificient material is present 3 reached and the device C detects sufiicient material before it, only belts 6 and 7 will move forward. The belts 8'and 9 will be stationary. Likewise, when only the belt 9 is filled, belts 6, 7 and 8 will move forward.
- FIG. 4 illustrates schematically a block diagram of a system utilizing series and parallel connected latching relays.
- the controls have been marked 20, 21, 22, 23 and 24.
- the belt actuators which may be electric -motors or clutches, have been marked 25 to 29 and the devices A to D are in boxes 30 to 34.
- the device A in the box 30 gives either a high signal or a low signal.
- Each of the devices C and D gives either a signal that goods are present or that goods are absent.
- the device B gives either a high signal or a low signal.
- control 20 for the belt gets a high signal it switches the actuator 25 on.
- control 26 gets a high signal which causes it to switch on the actuator 26 if the latter is not already on.
- control '20 switches the actuator 25 off while the control 21 sets itself in a position which would switch 01f the actuator 26, unless a signal from elsewhere otherwise dictates.
- the controls 21, 22, 23 and 24 switch on the actuators 26, 27, 28, 29 as the case may be.
- the actuators 26, 27, 28, 29 as the case may be.
- an absence signal they set themselves to the switching-oh. position. As each except the last 29 can get two absence signals or two presence signals, the presence signals take precedence over the absence signals.
- the device B feeds either a high or a low signal to the control 24.
- On arrival of a high signal it sets itself in such a position that the presence or arrival of a presence signal from D is blocked'so that the actuator 29 is not switched on.
- combination of the presence signal and the high signal feeds back to the control 23 where the fed back signal acts in the same way as the high signal in the control 24.
- the control 23 feeds back to the control 22 and that inturn to the control 21. In practice by the time that both a fed back signal and a presence signal are present in the control 21- an alarm will go off or the 'whole system will become immobilized.
- each control 20 to 24 incorporates a delay so that an actuator 25-29 is not immediately switched ofi or switched on. This is done in order to give any belt a short time to clear its load before being switched 013? or to accumulate a bigger load before it moves forward.
- heaps of the" articles are formed in the one part of the bin and the transported-over a series of belts to the other end over the bridges between the belts.
- the other end fills up and movement of the belts is controlled from the hopper into which the articles are dc posited.
- the main reason for the series of belts is that the section towards the end can be stationary when other heaps are brought forward. This prevents unnecessary chafing of the articles while a bundle is brought forward to join those that are stationary at the end.
- a storage bin comprising:
- first sensing means for sensing the level of goods adjacent the fixed wall
- second sensing means for sensing the level of goods at the discharge zone
- third sensing means for sensing the presence of goods at a predetermined level over the start of the third band, i.e. the end of the third band nearest the fixed wall; intermediate sensing means similar to the third sensing means at the start of each band after the third;
- a storage bin as claimed in claim 2 including means for maintaining the orientation of the rod-shaped articles in the bin.
- a storage bin as claimed in claim 3 wherein the means for maintaining the orientation of the rod-shaped articles is located substantially over the second conveyor from the fixed wall.
- a storage bin for storing loose. goods on a throughflow basis comprising an elongated trough, a fixed'wall at one end of the trough, means for feeding goods to the bin adjacent the fixed wall, a discharge zone at the end of the trough remote'from the fixed wall, at least three endless conveyor bands arranged end to end in the floor of the trough, high and low level detectors adjacent the fixed wall and over the discharge zone, detectors for detecting the presence of goods at the start of each band after the second from the fixed wall, and means so to control the movements ofthe endless bands that the two bands'nearest the fixed wall move together when a high level isdetected adjacent the fixed wall until a low level is detected adjacent the fixed wall, that belts after the first move when the presence of sutficient material on them is detected, and that when the high level is detected over the discharge zone the last band and bands preceding it on which material is detected are prevented from moving until the low level is detected over the discharge zone.
