Description

Device for connecting the end of a roll running off, into a processing machine, e.g. B. a printing machine, incoming cardboard tape with the beginning of a new cardboard roll for printing machines are different devices has become known to the end of a paper web running off a roll with the Beginning to join a new role. However, these connecting devices had to controlled by the operator of the machine; above all it was with different ones Devices necessary to reduce the operating speed of the printing machines. In order to carry out the actual connection process by machine, there is a device became known which one of the two paper or cardboard tapes retaining device as well as a carriage that can be moved transversely to the direction of the air flow and which is used to cut the straps Knives and the rolls of adhesive tape.

In addition, this known device has special lifting members to separate the cut cardboard parts. This is also the case with this known connecting device however, the operator of the machine must initiate the connection process, as this Note the incoming end of the running belt and the working speed must throttle. Only after this process can the mechanical connection with the help of the transversely movable carriage can be started. If rnan with this well-known establishment does not want to accept the complete shutdown of the printing press, it is necessary, appropriate lengths for the entire duration of the connection process to have paper web material ready.

Such devices are, however, for high-speed printing machines, as they are used, for example, for the production of punch cards, unsuitable.

The cardboard tape is removed from the roll with a Feeding speed of around 3.50 to 4.00 m / sec, making the timely A management of the connection process by the operator of the machine is almost impossible is, apart from the temporary reduction in working speed such "high-speed runners" require special technical measures.

The invention is a connecting device that during the running of the processing machine or printing machine the connection process of the an end of a running paper or. Cardboard web with the beginning of a new one Paper web performs completely automatically. A is also used for connection Carriages that can be moved transversely to the direction of travel of the belts and with which the belts can be separated Knives and using the rolls of tape for the butting ends as well a storage device. The automatic connection takes place according to the invention in that each cardboard tape in a known manner in front of the connecting device a storage space and moreover - seen in the running direction of the belts - two in a row and lever contacts attached at a distance from one another are assigned, of which each time the belt runs out, the lower drive roller pairs alternate with each other and upper drive roller pairs of the other web and the other contact a braking device for the running cardboard web as well as the trolley for cutting and connecting the Cardboard webs and for ejecting the remaining parts. The previously stationary reserve cardboard belt thus becomes a running cardboard strip for the processing machine or printing machine, so that in the side of the device from which the previously running cardboard tape has expired, a new reserve cardboard tape can be introduced without it the working speed of the processing machine needs to be reduced.

According to an advantageous embodiment of the subject matter of the invention are of the drive roller pairs in each case one drive rollers by means of a Motor drivable, while the other drive rollers with the help of solenoids one of the drive rollers can be pivoted. With switching on one or the other other upper pair of drive rollers to introduce those who remain calm Cardboard web in the connecting device is then a longitudinally displaceable between the webs Guide shuttle effective for separating the running from the stationary cardboard tape.

The object of the invention is based on an embodiment for a punch card printing machine explained.

The object of the invention is to end an expiring To connect the cardboard tape with the beginning of a new cardboard tape fully automatically, to make a connection between the two ends of the tape. The cardboard tape is alternating and successively from one of two adjacent ones, the connecting device assigned tape rolls and taken to a machine for the production of punched cards, in particular printing machines, supplied.

Either of the two supply rolls can take effect at the given time The current source of tape for the presses, while the other role is the source of reserve tape forms. If the cardboard tape runs out or is running out of the effectively running tape source. leaks or a crack of the same between the connecting device and the supply roll enters, the device automatically connects the end of the moving paperboard tape for the printing press with the stationary end of the tape of the reserve roll. Consequently there is a continuous supply of the cardboard tape, which alternates from the cardboard rolls while a certain working period of the machine is fed to the cardboard belt.

The running cardboard tape is used to carry out a connection process stopped for a short period of time, during which it was with the carton tape connected by the spare roll.

During this time interval, the printing machine receives the cardboard tape from a storage that is formed by a special roller device.

Immediately after the connection and the renewed movement of the cardboard tape through the connection station of the machine, the roller device accelerates the Speed of the cardboard tape running off the supply reel in order to reduce the during The amount of cardboard tape removed from the storage device during the connection process to catch up again.

The device receives the tape from the spare roll and moves it the same thing automatically in the connection section in which it is in the correct Position and for the connection with the running carton tape is already held. This applies to any cardboard tape coming from the spare roll, and it is only necessary hand the end of this tape a short distance into the insertion slot of a of the two tape storage devices. A stock of cardboard tape is stored in these stores kept ready for removal during the short time interval. This is necessary because the tape reel before the point in time in which the cardboard tape passes directly through the processing machine is withdrawn from the spool, is driven accelerated. That in the storage room Saved carton tape is also for use by the machine operator available to introduce it into the special caster mechanism of the connecting device and introducing into the processing machine, e.g. B. printing machine to be able to thread. The amount of cardboard tape stored is sufficient for this purpose without it being peeled off of tape from the supply reel is required. During the preliminary preparation, if there is still no cardboard tape from the two supply reels into the connecting device is inserted, the machine automatically conveys the inserted end of the cardboard tape from the slot through and over the connecting section out to a point where the end of the carton tape is taken from the machine operator can be taken and the mentioned introductory processes can be completed.

The processing machine, e.g. B. the printer came from a standstill accelerated to full speed without motor speed control be that the cardboard tape quickly and with little force on the amount of automatically cardboard tape present in the memory is withdrawn. In this case it will be repeated Cardboard tape introduced into the storage area; however, this is done on a smaller scale Extent compared to the amount of tape already delivered by the store, so that at the time at which the tape is completely removed from the store, the delivery reel is already accelerated to almost its normal rotational speed. Thereupon takes the processing machine takes the tape directly from the supply reel. The Swivel castor device as a bumper, while the processing machine the Supply spool accelerated to full speed.

After the processing machine has been switched off, a brake applies the running tape roll automatically to a standstill, and the tape tension will maintained by the caster mechanism. Immediately after the processing machine has come to a standstill, the brake for the tape reel is automatically released, to allow the caster assembly to return to its normal position, in which the normal amount of tape supply is stored.

The establishment of the connecting device should now be connected are described in detail with FIGS. 1 to 4 a, and these figures can be seen that two tape feeds to the one located in the upper middle part of the machine Connection section are provided. These tape guides are essentially the same, and the corresponding parts of the two guides are given the same reference number and only differ in the letters "A" and "B".

A cardboard tape PVß runs from a supply reel 50B from a shaft 51B fixed in the base 52 of the connector. A another cardboard tape PVA is pulled off an identical tape roll, not shown, in a similar way in a position to the right (in the sense of Fig. 1) of the device is supported. A brake disc axially displaceable on the spindle or shaft 51B 53B (Fig. 3a) cooperates with the front face of a stationary solenoid housing 54B together to decelerate the roll of tape during certain times, such as later will be explained. The spindle 51B also carries a brake ring 55 (Fig. 2), which cooperates with the brake shoes of a tension control device 56B, which is operated by a tension solenoid 57B is operated to maintain proper tension on the paperboard tape to hold when this is pulled from the tape roll, and thereby an excessive To prevent running off, for example by reducing the diameter of the tape reel could occur when the tape runs off. A tape tension sensing arm is provided for this purpose 59B (Fig. 4) is provided to measure the tension of the paperboard tape and a switch 60s to thereby control the energization of the voltage solenoid 57B.

The cardboard tapes l'J and IVB go through a neck-like passage introduced into the associated storage space of the connecting device. At the entrance In this passage a lower guide roller 61B is arranged, driven by a guide roller motor 62B is driven. The tape runs over this role and is against it during of the feeding operations pressed by a lower pressure roller 63B, which is of a Pressure solenoid 64B is operated. The lower sensing arm 59B is pulled through the cardboard tape WB moved clockwise (Fig. 4) into or beyond a middle position, in which it closes the contact of a lower switch 66B. The presence tension in the carton tape causes the lever arm 59B to move across the middle position, and the amount of that rotation is a function of height this tension. If a predetermined minimum of the voltage is exceeded, arm 59B actuates switch 6OBE The cardboard tape is fed through a wire guide 68B forced itself up along an inclined slide 67 of the storage space to move. The wire guide 68B is around peg 69B near the entrance to the Storage space rotatable and a cross bar 70B attached to it actuates a rotatable one Lever-65B. This latter enables a switch 71BJ to be opened as often as it can the storage space begins to fill with ribbon bows, like this is shown in FIG is. The cardboard tape moves up the inclined slide 67B under the arm of an upper tape lever, which when the cardboard tape passes through a keeps assigned contact open. The cardboard tape becomes an upper guide roller 73B (Fig. 4, 5) and against this by a rotatable angle lever 73B 2 seated roller 73B 1 pressed. The angle lever 73B 2 is with a handlebar 73a, which has a slot and pin connection with a pin 73 d rotatable lever 73 c and at the same time connected to this by a spring 73 b is. The lever has a slot and pin connection with one on a shaft 73 f seated actuating arm 73 e. An angle lever 73 attached to the shaft 73 J g (FIG. 4) is connected to the core of a solenoid 74 by a link 73 h. The upper guide roller 73B is rotatably seated on one of a coupling and a flexible cable 75B (Fig. 2) driven shaft, and the cable 75B is from the motor 62B driven via a reduction gear 76B. The clutch enables rotation the roller 73B drifts through the moving belt at its speed, but otherwise the roll the cardboard tape.

The lever arm 73 e controlled by the solenoid 74 is through a handlebar 73 i connected to a guide shuttle 90, which is during the tape insertion moved upward in the connecting part of the device to remove the moving belt to separate the other tape inserted into the connecting portion. The lower The end of the guide shuttle is secured by lateral pins and guide slots (not shown) forced to a reciprocating movement in the vertical direction, and its upper end moves in floating relationship between the upward protruding ends of the slideways 67A and 67B of the storage compartments. The top end the guide shuttle is designed like a sawtooth to resilient fingers (Fig. 5a) to form, alternating one side and the other from the plane of the guide boat An interlock switch 330 closes its contact when the guide shuttle 90 is pulled down to its lowest position. The switch 330 prevents how will be described later in connection with the circuit diagram, the movement of the Carriage for the connection, except when the guide shuttle is in its lowest Position.

The area for connecting the cardboard tapes is shown in FIG. 1 denoted by the reference numeral 77, and its structure and effect will be explained later described in detail. The running tape is through this area and across a tension control roller 78 is guided mechanically with a tension motor 79 connected is. The tension of the cardboard tape is achieved by the motor 79 (Fig. 2), which acts as a drag brake and by the overspeed of the running Belt is driven during normal operation. The engine 79 is an induction motor and withstands any attempt to drive it beyond the synchronous speed to drive. The drag force provided by the motor is proportional to the applied field strength and the extent of the overspeed, and thus can through the correct selection of the diameter of the tension roller 78 and the field excitation of the motor 79 provides the desired carton tape tension during normal conditions during the processing of the cardboard tape by the processing machine intended will. In the mechanical connection between the motor 79 and the tension roller 78 an overrunning clutch, not shown, is provided, which is aligned so that the belt drive the motor, but the motor cannot pull the belt. The cardboard tape is pressed against the tension roller 78 by a pressure roller 80.

A cardboard tape brake (Fig. 3b) contains one on the hub of the tension roller 78 split-pin and axially displaceable brake disc 78 a, which is the end face of a Solenoid 78 b attached to the machine frame is opposite. The engagement between the tension roller 78 and the pressure roller 80 is strong enough to hold the cardboard tape to hold against the full tension developed by the caster system when the band brake becomes effective. The task of this band brake is to keep the running Stop tape when the connector and its associated equipment are automatically stopped as soon as in the time at which a connection should occur, the other cardboard tape is missing.

The braking takes place sufficiently quickly, so that the end of the current Cardboard tape in the storage space is stopped and the normal joining process can be continued when the other cardboard tape then into the other column is introduced.

This causes the tape to be fed back through the connecting device and the associated equipment avoided.

The paperboard tape runs free from the tension roller 78 to a first one running roller 81 of the swivel roller unit 82. which is rotatable about an axis 83 (FIG. 1) is and under the action of provided in a cylinder 84 springs on a second arm 85 of the castor unit 82 attack, normally in the Fig. 1 is held in the basic position shown. The cylinder 84 forms at the same time a brake cylinder that prevents the castor unit 82 from moving too quickly in prevented their rest position. The fabric tape then runs over one on the machine frame rotatably mounted free-running roller 86 and further via a second free-running roller Guide roller 87 of the castor unit and finally via a guide roller 88 on the machine frame to the processing machine. One of the caster unit associated contact 82a reduces the field excitation of the voltage motor 79, whereby the cardboard tape at greater speed from the connecting device directly after the completion of a connection the carton tapes moved and the during the Time interval for the connection, the amount of tape removed in the swivel roller unit is replaced again.

For the purpose of explanation it is assumed that initially only one roll of cardboard tape in one side of the machine, e.g. in storage space B for the cardboard tape WB1, is inserted, while the storage space on the other side of the machine remains empty. After the end of the cardboard tape has been inserted into the associated guide neck of storage space B, the lower lever contact 66B is closed by the cardboard tape, and upon actuation of a push button 89B (FIG. 1), a motor 62B starts to rotate insert the cardboard tape into the storage space. Similarly, the solenoid 64B energized to pivot the pressure roller 63B and the paperboard tape against the lower one To push the drive roller 61B, which is now driven by the motor 62B and that Carton hand moved up along the inclined slide 67B of the storage compartment. The cardboard tape is by the at this point in time essentially parallel to the Slideway 67B forced guide wire 68B to move along the slideway 67B to move. The carton hand then moves under the lever contact 72B, the has no effect during tape insertion, and is then removed from the upper guide pulley 73B and the pressure roller 73B 1 assigned to it (FIG. 5). The pressure roller 73BX is pressed against the guide roller 73B by solenoid 74, and the excitation of solenoid 74 occurs simultaneously with energization of solenoid 64B.

As already explained, the upper guide roller 73B is driven by the motor 62B driven via flexible shaft 75B and gearbox 76B. The peripheral speed of the upper guide roller 73B is such that the movement of the carton tape is only one Fifteenth of the movement of the paperboard tape caused by the lower guide roller 63B is, so that a cardboard ribbon sheet is formed in the storage space B through which the wire guide 68B is rotated about its pivot 69B.

As a result of the excitation of the solenoid 74, the guide shuttle 90 is also activated at the same time (Fig. 5) moved up and into the work area to connect the cardboard tapes. The cardboard tape, which at this point in time by the upper guide rollers 73B and 73B1 is guided into this area, moves along the upstanding End of the slideway 73B of the storage space and between lower brake shoes 91 and 92 and through guides 93, 94 on the connecting carriage 95, which will be detailed later is described. Immediately above the guides 93 and 94 are deflection guides 96, 97 arranged under the assumption that the cardboard tape is first entering the machine is deployed, through associated solenoids 98 and 99 out of the way of the entering Cardboard tape are distracted. The cardboard tape consequently slides between the deflection guides 96 and 97, and an electrical time delay unit operates at this point the shutdown of the device. This causes the carton tape guide motor 62B stopped, the spool brake solenoid 54B energized for a short time interval and solenoids 98 and 99 for the deflection guides and solenoid 74 for the pinch roller currentless.

The pinch roller solenoid 64B remains for a short time interval energized longer to prevent the carton tape from overflowing while the reel is running 50B is braked to a standstill. The carton belt is stopped in such a way that that its leading edge protrudes just above the connecting portion of the device, so that it be grasped by the operator of the machine and pulled out of the storage space B. can. The carton tape is then manually moved over the castor unit 82 the exit guide roller 88 to the processing machine, e.g. B. the printing press, brought.

The automatic insertion of a cardboard tape into the other side the machine is the same as the process described with two exceptions. The new in the area 77 entering cardboard tape is by the guide shuttle 90 of the separated from the other side of the machine by the area running cardboard tape held and is also passed between the guides 94 and 93 of the carriage 95; but since deflection solenoids 98 and 99 are not energized at this point, will the incoming cardboard tape through the curved fingers of the guide boat 90 and through one of the deflection guides 96 or 97 into a free zone 100A or 100B deflected where the carton tape is associated with the arm 101A or 101B of a Lever contact 102A or 102B operated. The actuated lever contact interrupts the 62A or 62 induction motor circuit and the pinch roller solenoid excitation circuit 64, or 64B and closes the excitation circuit of the brake solenoid for the supply coil, from which the newly introduced cardboard tape is pulled off. The pressure roller solenoid 64A or 64B remains energized for about 1/4 second to loosen the cardboard tape during the time interval required to decelerate the supply reel to a standstill to prevent. The solenoid 74 is also de-energized at the same point in time, see above that the shuttle falls back from the connection area in its normal position. In this way, the newly fed cardboard tape is automatically in the area 77 introduced for connection to the running carton belt. where it is in one position for the connection with the one running through the connection area during this time Cardboard tape is held.

The operation for joining the two cardboard tapes will be automatically when the end of the moving tape is sensed by the lever contact 66A or 66B, i.e. when the cardboard tape runs out of the supply reel or at a break in the ligament. In the further description it is assumed that the cardboard tape has run through the B-side of the device and that the end of the band sensed by the lower Helel contact 66. This contact causes when it is opened in a manner to be described later, the monitoring of the expiring Tape for connecting the two cardboard tapes TVA in the carriage 95, TYB With this assumption, the cardboard tape in the A-side is the Device the stationary belt. The lower lever contact 66 also causes the start-up of the lower idler motor 62A and the energization of the associated pinch roller solenoid 64A. The lower guide roller 63A therefore transports more cardboard tape into the storage space A, and in doing so, the reel is driven through the unwinding tape at the required speed brought.

Wenii the end of the running cardboard tape TYB at the upper lever contact 72B (Fig. 4) passes, this contact is closed and a brake clutch energized, which initiates the drive of two brake cams 105 (Fig. 5). The cams 105 control the movement of two cam follower levers 108 and 109 that work with their rollers 106 or 107 rest on the front surfaces of the two nocl; s. The cam follower lever 108 is connected by a rod 110 to a second angle lever 111, which is below the tension of a spring 103 is and is rotatable about 112. The cam 105 and his Follower levers 108 allow the angle lever 111 to move under the action of the spring 103, around a brake shoe 113 and at the same time through two in engagement with one another stationary gears 114 have an opposing brake shoe 115 against the current one To press cardboard tape and bring it to a standstill. The cam follower lever 109 is similarly connected by a rod 116 to an angle lever 117, which moves when the cam rotates under the action of an associated spring 104 and a lower brake shoe 118 and over the meshing gears 119 the opposite brake shoe 120 against the running cardboard tape presses. the Cam 105 therefore cause the upper brake shoes 113 and 115 and the lower brake shoes 118 and 120 against the running and the stationary cardboard belt in the area of the two connection points. The cams 105 are designed so that the lower brake shoes 118 and 120 a few milliseconds earlier than the upper ones Brake shoes 113 and 115 applied and that the upper shoes by a few milliseconds be lifted off in front of the lower brake shoes.

As soon as the running carton tape is braked, the carriage 95 becomes for the connection of the two cardboard tapes across the two now stationary cardboard tapes emotional. The carriage 95 carries opposite paper cutting rolls with lifters, by means of which the ends of the cardboard tapes are cut to match and then be lifted to the previously introduced into the carriage, the belts with each other connecting adhesive tape by means of two pressure rollers following the cutting device to press against the cardboard bands.

With the movement of the connecting carriage 95 across the cardboard belts the connection of the two cardboard tapes is therefore completed, followed by the further Movement of the cams 105, the brake shoes 113 and 115 and then the brake shoes 118 and 120 are released and the connector moves out of the connection area begins to move out. The cutting rollers, the lifters and the pressure rollers of the Carriages 95 are moved apart at the end of the carriage's movement. The car 95 also carries free-running roles, which interact with one of four driven ejector rollers 123, 124, 125 and 126 are brought to the cut To grasp the ends of the cardboard tapes and slide tracks 127 and 128 into storage containers to transport. The carriage 95 then returns in the open state transversely to what is now running Cardboard tape WA back to its starting position, in which position its the connection serving elements in the normal closed state and in readiness be deferred for a next connection process.

FIGS. 6 and 7 show one carried out in the manner described Connection of the cardboard tapes in plan and elevation. The cardboard tapes WB and W4 butt with the cut edge S together, and the adhesive tape T uniformly overlaps the two colliding cardboard bands. The tape T is around one outer edge of the connected cardboard tapes around and pressed on both sides, and the two ends of the adhesive tape T extend to the opposite outer one Edge of the connected cardboard tapes W1 and W2.

When the running cardboard tape to initiate a joining process is stopped in the manner already described, the castor unit 82 (Fig. 1) moved clockwise to the processing machine during the for the connection of the running, but now stopped cardboard belt is required To be supplied with cardboard tape at intervals. As mentioned earlier, between the Tension motor 79 and tension roller 78 an overrunning clutch arranged so that the cardboard tape drive the tension motor, but this does not pull the tape can. When the connection is terminated and the - band brakes 113, 115 and 118, 120 are released, the caster unit 82 reverses under the action of the springs 84 returned to their normal walking position. During this Provision the amount of Rarton tape removed during the connection interval is repeated the caster unit is stored, and the tension motor 79 is accordingly driven by the carton belt at a speed that is greater than normal Speed is given by the normal needs of the processing machine is. The tension motor 79 therefore provides a greater braking effect until the caster unit 82 has finally returned to its normal position.

In the particular embodiment of the connecting device described the processing machine requires a cardboard tape feeder at the speed of about 4.5 m of tape per second, and the input guide rollers 61A or 61S guide the cardboard tape into theirs at a speed of around 3.5 m per second allocated memory space A or B, so that there is an actual loss of approximately 0.9 m of the stored tape length per second. In this case the saved Tape length in around 5 seconds after the connection process is completed taken from the memory, whereupon the cardboard tape is pulled directly from the supply reel and their speed increase from about 3.30 m per second to about 4.5 m per Second, it is balanced by the increased tension and the shock by the swell roller unit 82 is recorded.

The opening carriage 95 runs with several rollers 130 (Fig. 5, 8, 9, 10) on slide rails 131 and 132 of a stationary cast body 129, which is attached to a mounted across the upper part of the connecting device projecting plate 133 is.

A rack 134 arranged on one side of the carriage meshes with a gear 135 through which the carriage during a connection process is moved back and forth. Two rotatably mounted on the carriage by means of pins 140 and 141 Levers 138 and 139, respectively, carry opposing cutter rollers 136 and 137 and are normally held in a position by a spring 142 in which the cutting rollers 136 and 137 are separated from each other.

In the initial position of the car and in its readiness for The arms 138 and 139 are connected through the tapered end 143 of a locking rod 144 held in the closed state. The rod 144 is for their reciprocating movement in the longitudinal direction of the carriage in a socket 145 and is forced into its locking position by a spring 146 and in this position by one carried by the bushing 145 and in a groove 148 of the Locking rod engaging pin 147 held. The carriage 95 moves during the Connection to the right in the sense of FIGS. 8 and 9, and towards the end of its movement pushes the end of the locking rod 144 against a stop 149, whereby in the further Movement of the carriage moves the locking bar 144 to the left in the carriage and tapered it End 143 is advanced from the end of levers 138 and 139. The two levers 138 and 139 are moved to their open position by their spring 142, in which the cutter rollers 136 and 137 are separated from each other.

After the connection is terminated, the carriage moves to the left, and shortly before the end of this movement, a flange 150 pushes through which the locking rod 144 protrudes against one of the plate 133 attached stop 151 and against a stop 151a attached to the cast body 129. As the carriage continues to move in its normal position, the flange 150 effects the return via the spring 146 the locking rod 144 in the position in which its conical end 143 again mic the ends of levers 138 and 139 together to bring them closed Position to move.

The front ends of the levers 138 and 139 carry (by means of not shown Waves) the pressure rollers 154 and 155, which grasp the adhesive tape 186 and under Roll pressure on both sides of the cut cardboard tape to make the connection to manufacture. At the front ends of the levers 138 and 139 is an upper support bridge 156a or 157a and a lower support bridge 156 b (not visible in the drawings) or 157 b attached, which carry pivot pins 158 at their rear end, which on the upper and lower sides of the levers associated yokes 159 ", 160a and 159, respectively b, 160b. Upper lifting members 161 are attached to the upper yokes 159 a and 160 a a and 162a and on the lower yokes 159 b and 160 b similar lower lifting members 161 b or 162 b attached. The parts 159 b and 161 b are covered and are therefore not visible in the drawings. The front ends of the yokes 159a and 159b are provided with pins 163, which in openings by means of the pin 165 at the end of the lever 138 rotatably attached yoke 164 protrude. In a similar way the Pins 166 at the front ends of the yokes 160a and 160b in openings of a means of the pin 171 attached to the front end of the lever 139 yoke 170. The yokes 164 and 170 are arranged to be actuated by a vane 172 of a shaft 173 which is seated in a bush 174 at the upper end of a bearing 175. One at the shaft 173 fixed arm 176 is rotatable by means of a pin 177 with a Yoke 178 (Fig. 10) connected, the opposite ends of which are rotatable with the cores 179 and 180 are connected by solenoids 181 and 182, respectively. These solenoids pose with their optional excitation the lifting members 161 a to 162 b depending on it whether the stationary cardboard tape inserted in the connection area on the left or right side of the moving belt.

The core 179 attracted by the excitation of the solenoid 186 rotates hence arm 176, shaft 173, and wing 172 counterclockwise, and the wing 172 engages the upper end of the yoke 164 and rotates it about the Pin 165 also counterclockwise.

At the same time the flight 1172 rotates in cooperation with the lower one End of the yoke 170 this around the pin 171 in the same direction of rotation. The yokes 164 and 170 move the upper yokes 159 "and 160a in the through their pins 163 and 166 Clockwise around their pegs 158 (FIG. 9) to their associated lifting members 161a and 162 so that member 161a moves between the carton tapes (and the link 162a moves outside the carton belts when the connecting carriage moves 95 moved to the right (in the sense of FIG. 9) during the connection process. Vice versa steer the yokes 164 and 170 through their mechanical connection with the lower yokes 159b and 160b, the lower lifting members 161b and 162b so that the member 162b enters between the cardboard bands and the link 161b is outside the cardboard bands moves when the vague moves to initiate a connection the both belts moved together to the right. The lifting members 161a and 162a are hence "hand adjustment" for one, members 161b and 162b for the other Setting used. The lifting links are adjusted in the opposite direction Direction of deflection to that just described when solenoid 182 is energized.

With this adjustment of the lifting members, the upper member 161a steers and the lower link 162b (or 161b and 162a) the remaining ends of the two Cardboard tapes out of the connecting station after the two cardboard tapes cut by the cutter rollers 136 and 137, which were cut off as they moved of the carriage 95 for performing a connecting process in front of the lifting members move.

Each of the two levers 138 and 139 has an elongated recess 185 (Fig. 8), at the rear end of which the cutting rollers 136 and 137 and at the front end of which the pressure rollers 154 and 155 are arranged. An adhesive tape 186 of the corresponding length, protruding through the recess 185, is in one position brought from which it is to be connected by the pressure rollers 154 and 155 Cardboard tape is pressed on.

The lever 138 of the carriage (Fig. 10) is at its front end with provided a rotatable about a bolt 189 yoke 188, which at its opposite Ends of two pressure rollers 190a and 190b that are freely rotatable about pins 191a and 191b wearing; the other lever 139 carries a similarly rotatable about the pin 193 Yoke 192 with an upper and a lower pressure roller 194 "and 194 b. The pressure rollers 190a, 190b, 194a and 194b are used with the car in cooperation with one of the driven ejector rollers 123 to 126 brought to the cut remaining Eject the ends of the cardboard tapes.

The carriage for the connection keeps the contact in its basic position a switch 338 (Fig. 9) closed to the excitation in this position of the carriage of the solenoid 74 for the guide boat and after the start to prevent the carriage movement from energizing the solenoid.

For the further description of the operation of the car it is assumed that that the running cardboard tape in the A-side and the stationary reserve cardboard tape are in the B series of the device. Before initiating the connection process The trolley required for these two belts is located in the I; ig. 8 and 9, and the levers 138-13-139 are locked by the locking bar 144 held in its closed position.

When the end of the running cardboard tape is at the bottom, the contact 66A control lever slides past, this contact is closed to the start of the motor 62 and a certain length of tape 186 to hold it together the tapes into the recess by a device (described below) to introduce the levers 138 and 139 of the carriage. The the cut ends of the Cardboard bands lifting members 161a to 162b are activated by the excitation of the solenoid 181 set in the time in which the motor 62B the cardboard tape in the storage space B promoted.

The will be discontinued under the assumed conditions Lifting members such that the lifting members 161a and 162b into the space between the two cardboard tapes and the lifting members 161b and 162a to the outside the cardboard tapes are deflected. As soon as the running carton belt is in the already is braked to a standstill in the manner described, the car is driven by the Gear 135 and rack 134 are moved to the right (in the sense of FIGS. 8 and 9) and the cutter rollers 136 and 137 cut the two cardboard tapes in one common to the belt axes normal plane. The lifting members 61a following the cutting rollers and 162b lift off the cut parts of the tapes to allow the adhesive tape to be pressed on 186 on opposite sides of the cut ends of the cardboard tapes to enable the pressure rollers 154 and 1-55. After moving the car into his At the extreme right, the joining process is complete, the cardboard band brakes are automatically released, as is the reserve tape in the B-side of the machine is moved out of the connection area and becomes the moving belt. At the At the end of the carriage movement, the locking rod 144 pushes against the stop 149, to the unlock levers 138 and 139. These levers are now assigned by the spring 142 brought into its open position, in which the cutting roller 136, the lifting members 161a and 162b and the pressure roller 154, all carried by the lever 138, from the cutting roller 137, the lifting members 162 a and 162 b and from the pressure roller 155 are lifted, which are carried by the lever 139. The pressure rollers are on this 190a, 190b, 194a and 194b moved against the driven ejector rollers 123 to 126, to pick up the cut ends and eject them into the waste containers. The cardboard belt brakes are now released and the carriage remains in its right position until the ejection of the cut ends is completed, whereupon he crosses the connected and now running cardboard tape is returned without the running of the To disturb the tape, since the carriage levers 138 and 139 are lifted from each other. at upon completion of the return movement of the carriage, the flange 150 encounters the stops 151 and 151a, whereby the locking bar 144 is moved to the levers 138 and 139 back to its closed position and ready for the next connection process bring to.

The device for inserting the adhesive tape to hold it together the two ends of the tape is shown in FIGS. The tape 186 has a pressure-sensitive adhesive layer on one side and is commercially available in Rolls supplied. Such an adhesive roll 200 becomes freely rotatable on a shaft 201 placed on top of this by a chamber inserted into an annular groove in the shaft 202 secured. The tape 186 is pulled from the roll 200 and over a guide roll 203 a roller swivel unit 204 and a free-running roller 205 and a Deflection bolt 206 led to a knurled belt drive roller 207. The role 207 sits at one end of a shaft 208 rotatably mounted in the cast housing 209, and a spiral gear 210 attached to the other end of this shaft meshes with that on the Shaft 256 seated drive gear 211.

As mentioned earlier, the tape is applied right before the start the connection process is introduced into the carriage for the connection and thereby lowering or damage to the unsupported by and above the carriage prevents protruding end of the tape. That Drive gear 211 is driven in a manner to be described so that there is one complete revolution executes and thereby the shaft 208 and the knurled 13and drive roller 207 by one and a half Rotations, whereby a certain length of the adhesive tape (in the following Trap around 11 cm! is withdrawn from the tape reel 200. The caster unit 204 provides stable peeling conditions in time, while the roll 205 and the Deflection pin 206 guide the tape to the drive roller 207.

A gear 212 seated in the middle of the shaft 208 drives over a Intermediate gear 213 and a gear 214 a shaft 215 mounted in the frame 209. At the top At the end of the shaft 215 sits a wheel 216 with a V-shaped rim for folding the Adhesive tape.

A folding roller217 protrudes into the V-shaped circumferential groove of the wheel 216, which are rotatable by means of a pin 218 on an arm 219 carried by the frame 209 is attached. The folding roller 217 is adjusted so that a small distance between her and the bottom of the V-shaped circumferential groove of the wheel 216 is present. The wheel 216 is running at a slightly greater speed than the tape drive roller 207 rotated to add a slight tension in the running length of the tape produce. This low tension causes a better retention of the generated V-shaped cross-section of the adhesive tape. The tape 186 runs off the capstan 207 over a free-running pulley 220 and between the wheel 216 and the folding roller 217 to produce the V-shaped cross-section. The tape formed in this way runs then via a guide 221 attached to the frame 209 into a position in which it protrudes over the car. In the embodiment of the device according to the invention requires the introduction of a certain length of tape into the car around 120 milliseconds, and it takes place just before the carriage begins to move to initiate the connection process. One on the frame 209 of the feeder for the adhesive tape by means of the pin 223 rotatably attached V-shaped swivel arm 222 has two arms 224 and 225, the former in the path of movement of the attachment 226 protrudes on the lever 138 of the carriage, so that when the latter is moved, the pivot lever 222 (Fig. 12) counterclockwise against the action of the return spring 227 is rotated. The spring 227 is on a triangular shape carried by the frame 209 Plate 228 attached. A wire loop protrudes through the slot 229 of the arm 225 230, the lower end 231 of which is in its advanced position by the connecting carriage extending band 186 is adjacent and the opposite end by means of a Pin 232 is rotatably attached to the end 233 of the triangular plate 228.

A knife 234 provided for cutting off the adhesive tape, the preferably has a serrated cutting edge, is attached to frame 209 and protrudes against the tape as indicated in Figs. Figures 13, 14, 15 and 15 a show the successive steps in the operation when pressing on of the adhesive tape on the cardboard tapes while connecting the two cardboard tapes. During the forward movement of the carriage from its rest position shown in FIG. 3 the pressure rollers 154 and 155 come into contact to initiate a connection with the adhesive tape 186 and press it against the edge of the cardboard tape. at the further movement of the carriage will the tape is pulled along and begins to turn around to bend the end 231 of the wire loop 230, as shown in FIG is. The wire loop remains in place until the band 186 is approximately 32 mm from the edge of the cardboard tape, at which point the approach 226 of the lever 138 on the carriage in contact with the end of the arm 224 of the pivot lever 222 arrives and this begins to rotate about the pivot pin 223. With this panning of the lever 222 causes its second arm 225 to rotate by means of its slot of wire loop 230 around its pivot 232, causing the tape to slack and temporarily becomes independent of the movement of the carriage. The tape can therefore after the impact on the edge of the cardboard strips to be connected between the pressure rollers 154 and 155 pulled and for a small distance on both sides of the paperboard tape be held in place without pulling the tape to the left, as shown in FIG Fig. 15 is shown. The further movement of the carriage brings the tape against the cutting knife 234, and there at this point the adhesive tape through the pressure rollers 154 and 155 is held on both sides of the braked cardboard tape, it becomes cut by knife 234 as a result of the tension created.

As the carriage continues to move, the extension 226 slides over the end of the arm 224 of the pivot lever 222 addition, and the spring 227 provides the Lever 222 and through its arm 225 the wire loop 230 in the rest position according to FIG 13 back. The pressure rollers 154 and 155 continue pressing the cut off Tape 186 over the area of the two trimmed cardboard tapes end the connection process. When twisting the wire loop 230 in its rest position puts the cut end of the adhesive tape 186 in the appropriate position Position back so that the next length of tape at the beginning of a following one Connection process can be advanced. As soon as the car with the now open When lever arms 138 and 139 return to their basic position, the projection 226 meets of the lever arm 138 against the rotatably fastened to the arm 224 of the pivot lever 222 be Lever part 224a and rotates it about its pivot pin 236, as shown in the partial view according to FIG. 15 a is shown. The extension 226 can therefore be attached to the lever unit 222 slide past, whereupon the lever part 224 by the spring 227 in its normal position is postponed.

To drive all moving parts of the device is a constant revolving motor 240 (Fig. 17, 18) is provided, which via the gears 241 and 242 a shaft 243 drives on which three pulleys 244, 245 and 246 and one Seated V-shaped pulley 247. The belts for the first three named pulleys have equally spaced transverse webs on their inner surface, which are in corresponding Slots in the pulley running surfaces engage and therefore a dragging of the belt on the pulley. The pulley 244 drives the Feed device for the adhesive tape 186, the pulley 245 drives a primary, pulley 246 is a secondary clutch, and pulley 247 drives the device for ejecting the cut pieces of the cardboard tapes. The various drives are under the control of optionally by solenoids actuated clutches in the specified order.

First of all, the drive shown in FIGS. 20 to 22 is used for the advancement of the belt. The pulley 244 is with the to driving pulley 249 coupled by a belt 248. If by the expiring At the end of the running cardboard tape, the lower lever contact 66A or 66B (Fig. 1 to 4) is closed, the clutch solenoid 250 is energized and a clutch 251 known execution effective to a shaft 252 for one complete revolution with the belt pulley 249 to connect. The inside of the clutch housing 251 b provided spiral spring 251 a has a stopping stop 251 c, which is used for disengagement the clutch of that in the de-energized state of the solenoid 250 in its basis returned anchor 251 d is detected. A rotatable locking arm 251 e falls into a Notch 251f of a washer mounted on shaft 252. After indenting the Coupling drives a sprocket 253 attached to shaft 252 via chain 254 a sprocket 255 seated at one end of the shaft 256. At the other end of the Shaft 256 sits the already mentioned gear 211 (Fig.11, 20) of the feed device for the adhesive tape, by means of which the measured length of this tape in the connecting carriage is advanced.

The task of the primary clutch drive is the brake shoes 113, 115, 118 and 120 (Fig. 5) to apply to the carton tapes in order to keep the running carton tape stopping immediately before connecting with the other, and furthermore, the work initiate the secondary clutch drive. The primary clutch drive is in the Figs. 23-26 are shown.

The belt pulley 245, which rotates continuously with the shaft 243, drives via a belt 258 is the idle pulley 259, and the belt 258 is Guided over freely running pulleys 261 and 262. The pulley 259 rotates the primary clutch shaft 263 by one full turn when it is energized Clutch magnet 265 by one of the upper lever contact 72A or 72B (Fig. 1, 4) the impulse triggered when the end of the moving cardboard tape passes and the The clutch engagement caused by this is mechanically connected to the shaft 263 will. The shaft 263 carries at its end the two cams 105 (Fig. 5), which the Control the application of the cardboard belt brakes.

A cam 266, which is also seated on the shaft 263, is actuated by its ridges 267 and 268 the control arm 269 of the secondary clutch drive.

The secondary clutch tridi is shown in FIGS. 27, 28 and 28 a. The control arm 269 is rotatably attached to a frame 271 by means of a pin 270, and its associated arm 272 acts under the influence of a spring 273 with a Coupling 274 together, which is also a spiral spring clutch.

The clutch spring comprises the hub of a pulley 275 which is driven by the pulley 246 on the main shaft 243 is driven via a belt 276. Therefore, when the control arm 269 is moved by the elevation 267 of the cam 266, his arm 272 unlocks the coil spring of clutch 274, creating a drive ratio is made between the pulley 275 and the shaft 278, at one of which End of a crank arm 277 is attached.

One also mounted on shaft 278 and provided with two teeth Locking disc cooperates with a spring-loaded locking lever 280 (Fig. 28 a) to stop shaft 278 when arm 272 disengages clutch 274.

The crank arm 277 is rotated 1800 before the control arm 272 again a tooth. the clutch 274 is detected, and is then rotated by a further 18QO, when the second elevation 268 of the cam 266 at its full revolution hits the control arm 269 actuated. The correct position of the crank arm 277 with reference to the increases 267 and 268 of the cam 266 is shown in Fig. 16, in which the crank arm is directed to the left, while the crank arm in FIG. 27 for better illustration the details have already been rotated a bit. The rocker arm 277 is through a handlebar 282 with a Schieher283 (Fig. 16, 29, 30) connected, which in a frame 284 straight is floating. The slide 283 is provided with a rack 285, which is in engagement with an intermediate gear 286, which in turn with a the shaft 288 attached gear 287 meshes. The shaft 288 also carries the gear 135, which, as already described, with the rack 134 (Fig. 8, 9, 10) of the connecting car is engaged. It can thus be seen that the carriage 283 and therefore also the carriage from the secondary clutch train under the control of cam 266 in opposite Directions are moved within their limits of movement.

The drive device for driving the ejection device of the cut-off portions of the cardboard tapes is shown in FIGS. 31 to 35.

The belt pulley 290 running freely on the shaft 291 is held by the belt pulley 247 continuously driven on the main shaft 243 by a belt 292. The wave 291 can be connected to the pulley 290 through a coil spring clutch 294 under the control of an electronic device 295 are connected, against whose armature 296 normally a nose 297 of the clutch housing is supported. A spring loaded and rotatable locking lever 299 cooperates with a toothed locking disk 298 fastened on the shaft 291.

The shaft 291 carries at its other end a gear 301, which is mechanically coupled to shaft 291 by an overrunning spring clutch 302.

The clutch 302 is arranged so that the gear 301 of the Shaft 291 is rotated, and that the gear can continue to rotate when the shaft 291 stands still.

The gear 301 drives a shaft 307 via a gear 306, on whose the other end the ejector roller 125 is attached. The gear 306 drives over a Gear 308, shaft 309, at the other end of which the ejector roller 126 is seated. A Another gear 310 seated on the shaft 309 drives the gearwheel 311 via the gearwheel 311 Shaft 312, at the other end of which the ejector roller 124 is attached, and that too Gear wheel 313 seated on shaft 312 drives shaft 315 via a gear wheel 314 and the ejector roller 123 seated on this shaft.

In the following the operation of the device is related with the electrical circuit diagram (Fig. 36 to 41) described A three-phase transformer, of which only the secondary winding 320 is shown in FIG. 36, supplies after the closing of a manual switch 321 the required operating voltage, and the Motor 324 of the processing machine or the printing machine is controlled by a Relay 322 controlled contact connected to the transformer. One from the transformer fed rectifier (not shown) provides direct current of 150 and 120 VoIt for energizing the relays shown in FIGS. 37-41. In the following operations described are Examples assumed that take into account the two sides A or B of the connecting device. Each The operation described for the A or B side is for the opposite one Assuming the same. All you need is the controls assigned to side A, Contacts and relays through the control elements, contacts assigned to side B and relays are replaced.

Associated relays Cardboard tape side A j Cardboard tape side B 10 20 il 21 12 22 13 23 14 24 15 25 16 26 17 27 18 28 lPl t 1P2 Assuming that a roll of cardboard tape or reel is inserted into the A-side of the device at the beginning of the work, the lower lever contact 66A (FIG. 37) is closed and the relay is closed when the tape pulled off the reel is introduced into the entrance of the storage space 11 excited. The relay 11 prepares an excitation circuit via a relay 15 through its contact 11 AU U, which is closed when the push button assigned to the contact 89A is pressed. The relay 15 establishes itself through its contact 15 AU (Fig. 39) a holding circuit via the associated holding winding, through which circuit the relay 18 is excited at the same time. This circuit runs from the positive 120 volt conductor via the normally closed contact 2 C 2 of a delay relay 2 C, the now closed contact 15 AU> the normally closed contact 13BU and via the holding winding of the relay 15 and the excitation winding of the relay 18, the Line 337 and via contact 338 to earth. Contact 338 is controlled by the splice trolley and is closed when the trolley is in the correct position and ready to initiate a ligament splicing operation.

A parallel circuit branches off from this holding circuit via the normally closed relay contact 22 B U and the excitation winding of the relay 1 pl from. This circuit also causes capacitors C 19 and C 20 to pass the rectifier D 11 and the resistor R31 are charged and simultaneously via the now closed by relay 18 contact 18 AU a holding circuit via the holding winding of relay 18 established. The relay 15 also closes its contact 15 BL (Fig. 36), connecting the primary winding of a transformer 326 to transformer 320 and that connected to the primary side of transformer 326 Thermocouple 2 C causes contact 2 C 2 to open after approximately 2 seconds, whereupon the relay 1P1 the holding winding of the relay 15H and the excitation winding of the Relay 18 de-energized. Since, according to the assumption, the work process now running is used to introduce the cardboard tape, the deflection guides 96 and 97 (Fig. 5) controlling solenoids 98 and 99 when closing the Contact 15 BL through a circuit via the relay contact 1,4 and at the same time also the solenoid 74 for the guide shuttle, which also operates the upper guide rollers 73A 1 and 73B 1 excited.

When the relay contact 15 AL (Fig. 40) closes, a relay is activated 17 energized, which switches the associated contact 17 BL, whereby the capacitor C 25 through a circuit via resistor R36 and rectifier D 15 to positive 150 volt conductor is charged. At the same time, the relay sets up 17 assigned contact 17AU (Fig. 36) the excitation circuit of the voltage brake solenoid 57A via the clamping lever contact 60A.

The relay contacts 15BU and 17AL now close a circuit the insertion motor 624 (Fig. 36) and via which the adjustment of the lifting members controlling solenoid 181 and a circuit across the normally closed Contact 18 AL and solenoid 64A to adjust the input pressure roller. As soon the cardboard tape is passed through the exit of the storage space A, closes the upper lever contact 72A (Fig. 37) the excitation circuit for the relay R 12, the its contact 12 AL switches and thereby a circuit from contact 11 AU over the rest side of stop contact 102A, normally closed contact 24BU and established via relay R 14. As soon as contact 2 C 2 of the delay relay 20 is opened with a delay of approximately 2 seconds, the relay is activated 15 de-energized and interrupts the excitation of the Relay 17 or the solenoid 74 for the guide boat. The relay 17 switches therefore its contact 17 BL (Fig. 40) back in its basic position, so that the Solenoid 54A of the reel brake by the discharge of the capacitor C25 for the duration is excited about 1 second. The relay 18 will drop out at approximately t / 4 seconds delayed beyond the opening of contact 20 2 of the delay relay, because the charging of the capacitors C19 and C20 the holding winding 18H of the relay up to this point in time via the contact 18 AU keeps excited.

This leaves the pinch roller solenoid 64A over the shifted Contact 18 AL energized for a short period of time beyond the point in time in which the input motor 62A is de-energized by opening the contact 15 bs. Through this there is a slackening or a relaxation of the tension of the cardboard tape between the cardboard reel and the entrance to the store prevented. The cardboard tape is now inserted through the A-side of the device and can be accessed from the exit of the area withdrawn for the connection and introduced into the caster unit and from because the processing machine or the printing machine are fed.

This manual introduction of the cardboard tape into the swivel roller unit and into the processing machine is the tape supply stored in storage space A. exhausted with the result that contact 71A is assigned to that department Switch closed and the relay 10 (Fig. 37) is energized. The excitement of the Relay 10 is required to first energize the excitation coil of a relay 6 to be able to and then the rotor 324 of the processing machine by the excitation of the relay 2 controlling the motor switch 322 to start. This ensures a with regard to the amount of uniform storage of the cardboard tape in the storage space, since this storage always takes place from a state in which the cardboard tape flat or fas! flat on the inclined track 67A -or 678 des Storage space slides. The initially excited relay R 10 delays the start of the processing machine, while the now stationary cardboard reel in the A-side of the machine starts up and accelerates, a new supply of tape in the storage room A is filled up to an almost resistance-free tape removal by the processing machine to enable. If the amount of cardboard tape stored is sufficient, the Storage contact 71A is open and relay 10 is de-energized. Now is the connecting device in the state of starting their work, and at this point the relays are 10, 11, 12 and 14 energized. A cardboard tape sensing contact provided in the converting machine 328 (Fig. 41) is closed by the cardboard tape inserted into it.

The manually operated start-stop switch 329 (Fig. 41) of the Connection device must if it is in the start position at this point in time is to be switched to the stop position to a relay 5 through a circuit from the positive 120 volt conductor through the sensing contact 328, the one from the guide boat 90 in its lowest position closed contact 330 (Fig. 5), the rest side of contact 4AL and switch 329 to excite. The relay 5 is after his Excitation by the assigned contact 5 AU kept excited when the switch 329 is switched to its start position. In this position the switch is the circuit that excites relay 5 via the now closed contact 5 BL, the rest side of the contact 2 AL, the now switched contact 14 BL, the now closed contact 10AU, the rest side of contact 24BL and across the resistor R33 and the excitation winding of relay 6 continued. The excitation of the relay 6 establishes an excitation circuit across contacts 6AL, 14AL and the relay 17 (Fig. 40), which, when energized, switches the contact 17 BL to the capacitor Charge C25 via the rectifier D 15 and the resistor R 36. The charge of the capacitor C 25 is later used to excite the cardboard tape reel brake 54A, if the carton belt is to be stopped for any reason.

Since now the contact connected in parallel to contact 10AL (Fig. 36) 6BU and contact 17AL are closed, the induction motor 62A starts, and at the same time, the input pinch roller solenoid 64A becomes over the rest side of contact 18AL as well as the solenoidl81 for the adjustment of the lifting members are energized. The motor 62A accelerates the travel of the tape reel A in order to obtain a larger supply of the To store cardboard tape in storage space A. When filling this storage space begins, the memory contact 71A is opened under the action of the wire clip 68A and the excitation circuit of relay 10 (Fig. 37) is interrupted. The relay 10 thereby opens its contact 10 AU to the circuit via the excitation winding of the relay 6 to interrupt, and closes the contact 10 BU to an excitation circuit via the now closed contacts 14AU and 6AU and the holding winding of the relay 6 to build. The capacitor connected in parallel to the excitation winding of the relay 6 C27 prevents the relay from dropping out until its holding coil is energized.

The energization of the relay 17 also causes the brake solenoid to be energized 57A via contact 17AU, as often as switch contact 60A is closed.

Simultaneously with the holding winding of relay 6, relay 2 excited and established via its now switched contact 2'AL (Fig. 41) a holding circuit via the associated holding winding 2H. The one now too from relay 2 closed contact 22 (Fig. 36) completes the circuit the motor switch solenoid 322 so that the motor 324 of the processing machine, the Motor 240 of the connector and the tension motor 79 to the transformer 320 can be connected. The tension motor 79 is powered by an autotransformer 332 excited. The contact 82 ″ assigned to the swivel roller unit 82 causes a full field excitation of the motor 79 and thereby the desired maximum cardboard tape tension, when the castor unit is in the home position, and reduced the field excitation of the motor if the caster is in a for any reason a position corresponding to a higher voltage is moved.

The holding winding of the relay 6 remains excited as long as a Cardboard tape is located in the storage space, and it is after opening the relay contact 10BU de-energized if the relay 10 again when the storage contact 71A closes is excited. The excitation winding 6P of the relay 6 is closed when it closes again of contact 10 AU not energized because the excitation circuit is switched by the Contact 2AL of the relay 2 energized at this point in time is interrupted. If that Relay 6 is de-energized, its contact 6BU (Fig. 36) interrupts the circuits through lead-in motor 62A and through solenoids 181 and 64A.

However, the relay 17 remains energized after the relay 6 has dropped out, because the contact 2 BL of the energized relay 2 held in the excitation circuit of the Relay 17 (Fig. 40) located contact 6AL bridged.

The cardboard tape is now moved through the connection device, and relays 2, 5, 10, 11, 12, 14 and 17 remain energized. It is noted that At this point in time the relay 20 is also energized, since it is according to the selected Mode of operation no cardboard reel is located in the B-side of the machine and therefore the contact 71B of the storage space B is closed.

Assume now that the A-side of the device is equipped with a roll of cardboard tape is supplied and for continuous operation in the B-side of the device If a roll of cardboard tape is inserted, the lever contact 66B closes and becomes the relay 21 excited as soon as the beginning of the cardboard tape is inserted into the storage space B. The relay 21 closes its contact 21 AU, so that when you close the by hand from actuated pushbutton contacts 89B (FIG. 37) the excitation winding 25P a relay 25 is energized.

The relay 25 closes its contact 25AU and thereby sets a Circuit from normally closed contact 2 C 2 of the delay relay 2 C via the contact 23 BU and the holding winding 25H of the relay 25 and via the relay 28 connected in parallel. The closing of contact 25AU also causes the charging of the capacitors C19 and C20 via the diode D 10 and the resistor R30 (Fig. 39). However, relay 1P2 cannot be energized at this time, since the contact 12 AU in the excitation circuit is open, because the Cardboard tape in the A-side of the device, the upper lever contact 72A closed and relay 12 is energized.

The relay 25 also closes the contact 25AL when energized, so that the relay 27 (Fig. 40) is energized and its contact 27BL is switched over and thus the capacitor C26 is charged via the diode D 16 and the resistor R38.

At the same time, contact 27 AU establishes the excitation circuit via - the brake solenoid 57B and the cocking lever contact 60B. There is also the contact 25 BL (Fig. 36) is closed, the solenoid 74 for control of the guide boat 90 and the upper guide roller and the delay relay 2C energized, and the contacts 25BU and 27AL complete the circuits through the induction motor 62B and the solenoid 182 to adjust the lifting link he and the parallel circuit over the now by relay 28 toggled contact 28AL and the pressure roller ensoienoid 64B. the Holding winding of the relay 28 was via the contact 28AU by the discharge of the Maintain capacitors C19 and C20.

When the newly introduced cardboard tape is led out of the B storage space the upper lever contact 72B completes the energizing circuit of the relay 22. Since at this time the relay 1 P 2 is not energized and therefore the contact 1A (Fig. 36) is open, the deflection solenoids 98 and 99 remain de-energized, thanks to the Area for the connection running cardboard tape is deflected so that its end comes against the stop contact 102B. This switches this contact and the excitation circuit from contact 21 AU through toggled contact 22WI and 102B and relay 23 completed. The energizing relay 23 Open contact 23 bs (Fig. 39) interrupts the excitation circuit via the holding winding 25H of relay 25 and via excitation winding 28P of relay 28. It is noted that that also in the event of non-excitation of the relay 23 as a result of the not converted Stop contact 102Æ the relay windings 25 H and 28 P are de-energized because the contact 2 C2 with a delay of about 2 seconds after the excitation of the Delay relay 2 C opens.

When relay 25 drops out, the associated contact is interrupted 25AL the excitation of the relay 27 (Fig. 40), whose contact 27AL over the circuit the introduction motor 62B and through the solenoid 182 interrupts. As a result of the simultaneous Switching of the contact 27 BL becomes the spool brake solenoid 54B by the discharge current of capacitor C26 (Fig. 40) is excited. The holding winding 28H of the relay 28 remains about 1/4 second longer due to the charging of capacitors C 19 and C20 is maintained energized, and hence the pressure roller solenoid 64B also remains energized for a short time after the motor 62B was de-energized to slacken or looping the cardboard tape between the supply reel and the lead-in to prevent the B storage department. The delay relay 2 C and the solenoid 74 are de-energized when the relay contact 25BL is opened. It is noted that im B storage space usually stores a maximum supply of carton tape in time in which the end of the cardboard tape moves the stop contact 102s around the To energize relay 23 and thereby switch off relays 25 and 28. ' The cardboard tape is now inserted into the B-side of the connector and ready for the actual connection process. At this point the relays 2, 5, 10, 11, 12; 14, 17, 21, 22 and 23 excited.

The belt inserted in the A-side of the machine runs normally Way through the device, and as soon as the end of this tape at the lower lever contact 66A passes, this contact is opened and the relay 11 is de-energized. Since that Relay 11 opens its contact 11AU, relay 14 is also de-energized. Simultaneously the excitation circuit is from the positive through the now closed contact 11 BU 150 volt conductor itover the contact 23 AU, the switched contact 12 BL, the resistor R 24. the now closed contact 11 BU and via the excitation winding of the relay 26 closed. The relay 26 creates a holding circuit through its contact 26AU via its holding coil 26H.

The excitation of the relay 26 causes the initiation of a work cycle with the advance within the connecting device of the clutch magnet 250 (Fig. 38) by a circuit from the +150 volt conductor via the now closed Contact 26 BL, one of the resistor R23 bridged capacitor C 15 and one manually operated switch 335 (the one for a manually controlled feed movement is used). The duration of energization of the magnet 250 is determined by its impedance and the time constant of the capacitor C 15 is limited to one operating sequence. By the opening of the contact 14AL, the relay 17 is de-energized and its contact 17BL (Fig. 40) is returned to the normal position and the spool brake solenoid 54A excited by the discharge of the capacitor C 25. This will make the cardboard tape reel stopped in the A-side of the device. As a result of the now closed Contact 26AL and the still closed contact 2 BL, the relay 27 is energized, that through its contact 27AL (Fig. 36) the circuits from contact 20 AL via the Insertion motor 62B, via solenoid 182 for deflecting adjustment and performed through the solenoid 64B for adjusting the pressure roller. As soon as that End of the cardboard tape in the A-side of the device at the upper lever contact 72A passes], this opens and the relay 12 is de-energized.

The relay 12 puts its contact 12 BL (Fig. 38) in the basic position back, and since contacts 23 AU and 26 B U are closed at this point in time, the link clutch solenoid 265 and the eject clutch solenoid 295 are energized.

The excitation circuit of the clutch magnet 265 runs through a through the resistor R 25 bridged capacitor C 16, so that the work of the clutch by the time constant of capacitor C16 and the impedance of magnet 265 one revolution is limited. During this workflow, the running cardboard hand stopped by putting on the brake shoes, and then the carriage leads to Carrying out the connection a full working movement, meanwhile the four ejector rollers are also driven in the manner previously described After the cut pieces of cardboard tape have been ejected, contact is reversed 102B back to its home position, so that the relay 24 through the circuit from Contact 21 AU via the switched contact 22 AL, the rest side of the contact 102B and contact 14BU is energized. By changing the stop contact 102B the relay 23 is de-energized, and by the opening of its E-contact 23A U the relay 26 is also activated by the interruption of the holding circuit via the holding winding 26 H de-energized. The relay contact 24AL (Fig. 40) is shortly before to the Opening the contact 26 AL closed so that the relay 27 remains energized and consequently the capacitor C 26 via the switched contact 27 BL, the resistor R38 and the diode rectifier D 16 remains connected to the positive 150 volt line.

If now the cardboard tape for processing the B storage space is removed, the relay 20 is assigned to the storage space by closing the Contact 71B is energized and by t) opening of contact 20AL the circuit for the insertion motor 62B and the pinch roller solenoid 64B are interrupted.

As soon as the cardboard tape of the B-side of the device is the running tape is, the A-side of the device is empty and can be filled with a new cardboard roll will. At this point in the workflow, relays 2, 5, 10, 20, 21, 22, 24 and 27 excited.

The processing machine or printing machine and the connecting device can be stopped by moving the hand switch 329 to its stop position will. By moving the switch 329, the relay 2 is de-energized while the relay 5 remains energized. The relay 2 interrupts the AU through its contact 2 Energizing the motor switch relay 322 so that the motor 324 of the processing machine, the carton tape tension 79 and the motor 240 of the device for connecting the power source must be switched off.

If at this point the cardboard tape runs through the A-side of the device, the relay 17 is de-energized when the contact 2 BL is opened and via the in the reset contact 17BL, the reel brake solenoid 54A through energizes the discharge of the capacitor C25. The supply reel A is therefore braked. The contact 17AL interrupts the energization of the motor 62A of the pinch roller solenoid 64A and the solenoid 181 for adjusting the lifting links, if these are in should be aroused at this point. The drive of the processing machine can however, also interrupted by the opening of the carton tape sensing contact 328 (Fig. 41) be what can happen when the cardboard tape between the device for connection and the processing machine rips. The machine is stopped in the same way Same as when switching switch 329, but the relay is now also 5 de-energized.

Assume that the cardboard tape is over the 4-side of the device expires and in the B-side a cardboard tape for the connection with the expiring A-band is inserted, relays 5 remain when the machine is stopped normally, 10, 11, 12, 14, 21 and 22 energized. However, stopping the device comes through If the tape breaks so that contact 328 is opened, then these relays remain energized with the exception of relay 5.

Switch 329 is used to restart the affected units only its conversion to the start position required, since the relay 5 is energized stayed. By moving the switch 329 to the start position the relay 6 is energized via the relay contacts 5BL, 2AL, 14BL, 1OAU and 24BL. The contacts 6AL and 14AL (Fig. 40) close the excitation circuit via the relay 17, and by closing the contacts 17AL and 6 or the circuits are over the Induction motor 62A and solenoid 181 and circuit through contact 18AL for the pinch roller solenoid 64A completed. This puts cardboard tape into the A memory space is introduced and the memory contact is beginning to fill up 71A open and therefore the relay 10 is de-energized. The excitation winding 2P of the relay 2 and the holding winding 6H of the relay 6 are now through the circuit from the switch 329 excited via contacts 1OBU, 14AU and 6AU, and the holding winding 2H of the relay 2 is through the circuit from switch 329 through contact 5BL and the working side of contact 2AL kept energized. The rest of the process of resuming operations takes place in the same way as already described.

Was the machine-through the opening of contact 328 as a result of a Tearing of the cardboard tape stopped, with a soft process the relay 5 also de-energized has been, the first thing to do to restart is to switch switch 329 to its Stop position required to re-energize relay 5, whereupon the switch 329 is set in the start position and the processes already described are initiated will.

If there is a tear in the cardboard tape between the supply reel and the entrance to the storage compartment 61A or 61B and in the other side a cardboard tape is in readiness for a subsequent connection process, a normal workflow for the connection of the two cardboard tapes becomes effective, and the cardboard tape that was previously running through the device automatically becomes stationary Tape. However, if the cardboard tape is torn between the supply reel and the Entrance to the 4 or B storage room no cardboard tape in the other side of the device, then the running belt and the processing machine are automatically stopped. Is z. B. Assume that the cardboard tape running through the A-side of the device ruptures, the lower tape lever opens the contact 66A, and the relay 11 is de-energized. By opening the contact 11AU, the relay 14 is de-energized, which in turn the energization of the relay 17 is interrupted by the contact 14AL. The relay 17 sets doing its contact 17BL in the home position, causing the spool brake solenoid 54A is excited by the discharge of capacitor C25. At the same time that will Relay 4 by a circuit from the positive 120 volt conductor through contact 2 BL, the diode rectifier D 18, the resistor 1128 and via the contacts 21AL, 23AL, 13AL and 11AL energized. The relay 4 sets the contacts when it is energized 4AU, 4BL and 4BU (Fig. 36), thereby connecting the motor 240 of the device directly to the output lines of the secondary side of the transformer 320. Through the switching of the contact 4AL (Fig. 41) the relays 5 and 2 are de-energized and the magnet 78 b of the cardboard tape brake through the circuit via the contacts 5AL, 11AL, 13AL, etc. energized so that the carton tape is stopped. The capacitor C 17 (Fig. 39) in this circuit holds the relay 4 over the time of opening of contact 2BL is also energized, and after this point in time the brake magnet is 78 b kept excited via contacts 5AL and 4AL in order to stop the running tape.

After the connection device and the processing machine stopped in the manner just described, normal operation will be performed resumed after inserting a cardboard tape into the B-side of the machine. By inserting the cardboard tape into the B-side 009 rifj0 / 62 became relays 20, 21, 22 and 23 energized and this has energized winding 26P of relay 26 via contacts 23 AU, 12BL and 1BU and the excitation of the holding winding 26H of relay 26 via contacts 23AU and 26AU. By closing des, contact 26BL is the clutch solenoid 250 via capacitor C 15 and the manual switch 335 energized to the required length of the tape in the connecting carriage to introduce.

When the machine is stopped due to a belt break, the switch is 329 in its starting position.

By manually changing switch 329, relay 5 energized and the brake solenoid 78b de-energized through the opening of the contact 5 AL.

As a result, the swivel roller 82 can return to its basic position pulling the end of the cardboard tape through the side of the device and on the upper lever contact 72A so that it opens and the relay 12 becomes de-energized. When the relay 12 falls, the rest side of the contact closes I2BL, and it becomes the clutch solenoid 265 and the eject clutch solenoid 295 energized in the manner already described, followed by a normal connection process entry. The switch 329 is then set to the start position by hand, and a normal carton tape start-up process follows.

If a tear in the cardboard tape occurs between one of the storage spaces and of the processing machine, then the sensing contact 328 is opened when the The end of the carton tape reaches the processing machine.

This and the connecting device are then described in US Pat \\ trip paused automatically.

When the tear of the cardboard tape in front of the area for connecting the tapes has occurred, the end of the cardboard tape is simply back into the connecting device introduced and brought into the processing machine, and it can be a normal start-up process follow. Is the cardboard tape between one of the storage spaces and the connecting area torn, then a preliminary tape insertion process must follow.

It can happen that the two machines turned off.

The current side spool brake solenoid 54A or 54B then becomes via the rest side of contact 17BL or 27BL through the discharge of the capacitor C25 or C26 energized to slow the tape reel. After eliminating the power failure the units can be restarted in the normal manner already described will.

It should be noted that the relay contact 18 BL or 28 BL during the energization of the relay 18 or 28 and for about a quarter of a second longer the contact 330 controlled by the guide shuttle 90 bridged if during one normal insertion process of the closure set within the connection area will. After inserting the cardboard tape, the guide boat should be in its normal position Position outside the connection area must have returned before the actual Connection process begins. If this is not the case, then the precautions will be taken and the processing machine is automatically turned off because the shutter blocking contact 330 remained open and relays 2 and 5 were de-energized.
