Description
1 1 - 1 - 2201145 1 1, TITLE.._ Apparatus for monitoring -packing media in
packing machine s The invention relates to an apparatus for monitoring packing media in packing machines, for ascertaining the degree of consumption of a packing medium reel and tearing off of packing medium With detection and evalution elements, also a control apparatus for controlling the packing machine.
1 In packing machines. especially in.the high-output range, as for example in cigarette packing machines or sweet-wrapping machines. the endeavour is to switch these off as little as possiblT, for whie-h.reason automatic reel replacement units are provided, or to recognise faults in the packing medium supply quickly, eo that the rate of faulty packages is kept as low as possible.
Various solutions are currently known for ascertaining this information, and these solutions work independently of one another.
One solution for ascertaining packing medium defects has become known from DE-OS 3,341,539. For detecting faults in this case sensors consisting of an infra-red light emitter and a photo-diode standing opposite thereto are used, through between which the packing medium web runs. With this apparatus it is in fact possible to recognise faults including incipient tears in the packing material. but not complete tearing off of the packing medium web.
v Cxrrently opto-electric sensors (DE-OS 3,436,217) or mechanical scanning devices (DE-OS 2435,441) by which then a signal for tripping a switching action is given, are used for ascertaining the packing medium web ends.
While with these means fte-ends of packing medium webs can well be ascertained, if however a packing medium web tears off. they remain ineffective, for the presence of the packing medium-continues to be indicated. Transparent packing medium, such as unprinted cellulose glass, cannot "be scanned with these apparatuses.
The invention has the aim 1 of avoiding packing faults due to t.earing off of the packing medium or running out of the packing medium, of monitoring the stock of pacling medium and of redudingstoppage times.
The problem exists of ascertaining tearing off of the packi.n.g medium and the stock of paeking medium and of triggering switch indications and warning actions. In accordance with the invention the problem is solved in that on the reel shaft a pulse emitter is arranged which is in operative connection with a pulse counter integrated into a micro- computer. in that on the working timing shaft a timing pulse emitter is arranged and above the packing medium take-off roll a distance sensor is arranEed, and these are in operative connection with the counter through switch members integrated in the micro-computer. The micro-conputer contains a control part which is in 1 47 operative connection on the input side with the counter and on the output side with drive, indicator and warning devices. In combination with an ideal pulse allowance introduced into the micro-computer it is possible by comparison with the actual pulse number per working cadence constantly to monitor the degree of unwinding of the packing medium reel and thus to indicate in good time when this reel is running out.
If the packing medium reel comes to a halt due to material tearing off, the machine can immediately be halted automatically. All actions can be combined at the same time with an alarm device which can work acoustically or photoelectrically. Sources of faults can thus be recognised immediately and incorrect packings can be avoided.
The invention is to be explained in greater detail below by reference to an example of embodiment.
In the accompanying drawing-:, FIGURE 1 shows the highly diagrammatic packing medium withdrawal system with the scanning elements and the microcomputer in lateral elevation; FIG= 2 shows a block circuit diagram of the micro computer, in which the collected data are processed and transmitted.
As may be seen.fron FiEure 1, the packing medium withdrawal system consists of a reel suspension system designed for two packing medium reels 1 and 1.1, on each reel shaft of which a pulse emitter 2 and 2.2 is arranged.
1 1 The pulse eimitt..rs 2,. 2.2 are connected through switch members with a pulse counter integrated in a microcomputer 3. The packing medium webs 4 and 4.1 are conducted by way of deflector rollers 5 and 6 to an automatic packing 5 medium changer device 7 and thence one packing medium web 4.1 is conducted to two take-off rollers 8 and 9, which pre adjoined by a cutting device 10 which is a component of a wrapping station 11.
On the upper deflector roll 5 there are arranged- mechanically acting sensors 12 by means of which it is ascertained whether packing medium reels are inserted into the reel mountings. An electro-magnet 14 actuating the changer device is situated in the packing medium changer device 7. -Lbove the upper, liftably formed take-off roller 8 a distance sensor 15 is arranged. This is i n operative connection with a product-scanning device (not shown) arranged in thelvrapping station 11. All sensors are in operative connection onthe input side with the microcomputer. In a central gearing (not illustrated) there is a v:orking timing pulse shaft 16 whi ch is fitted eith a timing pulse emitter 17. This tining pulse emitter is likewise in operative connection on the input side with the micro-computer-3. On the output side the micro- computer is connected through a control device integrated in it with the drive -motor 18, the ragnet 14 of the packing medium changer, warning devices 19 which can be made as acoustic or photo-optital devices, and a magnet 20 for actuating a product directing device 21.
-i 1 1 4 J r 1 1 1 Several monitor functions., which are to be explained with reference to Figure 2, can be carried out with the apparatuses. Let it be assumed that the necessary initial data are inserted as programme parts into the micro- computer. With the switching on of the machine the sensor 12 scans whether a packing medium web 4 has been inserted. This signal is fed.to the micro-computer 3. Only in the case of a positive response is-a switch pulse emitted by the evaluator element, b y means of which the motor 18 is switched on. At this moment there is as yet no material for packing in the wrapping station 11, which is ascertained by the packing product scanning device. The take-ofif roller 8 is still situated, for this reason, in the lifted position so that no packing medium is yet dray.m off. The distance sensor 15 arranged above the take-off roller 8 scans the positionof the take-off roller 8 and signals no need for packing medium. This signal is fed into the micro computer 3. Since no fault is indicated by this switch action, the mach. ine continues to run although the timing pulse emitter 17.delivers a timing pulse T to the microcomputer 7 and the pulse emitter delivers no pulse 1, since in this case all control functions are blocked by the long-term pulse D delivered by the packing product scanning device. When material for packing is detected by the packing material sca nning device, this result is fed to the micro- computer _i.and by means of switch elements the take-off roller 8 is lowered, whereby the packing medium web 4 1 is grasped and unrolled. from the packing medium reel 1. Since the distance of the distance sensor 15 from the takeoff roller 8 is now greater, this new condition is fed as measurement resul-It into the micro- computer 3, whereby the long-term pulse D is cancelled and the timing pulse T becomes effective. With the withdrawal of packing medium the packing medium reel I and the reel shaft and the pulse emitter 2 connected therewith are set in rotation, whereby pulses I are delivered to the micro-computer 3. The counting duration is determined by the start and stop pulse triggered by the timing pulse emitter 17 ar-anged on the working timing pulse shaft 16. If the pulses I counted by the pulse counter 2 lie within a predetermined from-to value the machine continues to run in normal working. Since the pulse number increases with decreasing diameter of the packing.medium reel 1, the counted pulse number is used for indicating the stock of packing medium. For this purpose the counter is connected t hrough suitable coupling members with a display device 19.
If the packing medium reel I is running out, a pulse number is emitted by the pulse emitter 2, as a result of the high rotation rate, which is pre-stated to the micro computer as upper limit value. If the id&al and actual pulse numbers are equal, then through the sensors 12; 13 the control part in the micro-computer 3 is activated and the maEnet 14 is actuated, whereby the take-off rollers of the packing medium changer device 7 grasp the packing medium vieb 4.1 and feed. it to the take-off rollers 8, 9. With the 1 1 1 9 1 1 10 7 - running out of the packing medium web 4 the sensors 12, 13 indicate that no more packing medium is present here. Thus the pro'gramme for display of the packing medium reserve is started. Since with the change of the packing medium webs two webs lie one above the other for a time, some sweets are wrapped twice. So that these do not pass into the further treatment process, the magnet 20 is activated by the control part of the micro-computer 3, whereby the product directing device 21 is actuated and the incorrect packages are sorted out. If tearing off of packing medium occurs, the packing medium reel and thusalso the pulse emitter remain still. No more pulses I are fed into the micro-computer.3. Since the distance sensor 15 however signals need for packing medium and the timing pulse emitter 1? substantiates that the machine is running, the drive motor 18 is switched off through the control part of the micro-computer 3 and thus the mach ine is halted. At the_same time the delivery directing device 21 is switched ofer so-that no unpacked articles can arrive on the conveyor belt 22.
After the elimination of thelfault and renewed starting of the machine, t-,-,e programme for monitoring is started anew. After a few cadences the delivery directing device 21 switches back into the normalposition. Thus any unpacked articles present in the wrapping station still are prevented frors arriving on the conveyor belt 22.
