shells for purposes that will be explained later.

Valves 197t 205 and 220 are connected in compressed air lines which are used to supply compressed air to the respective ends of cylinders 33, 27 and 104, with the arrows pointing towards the respective valves representing the compressed air supply line while those from the respective one Arrows leading away from the valve represent the derivation. Furthermore, the switches 180, 169 '211 195t, 217, and 225 are each provided in a solohen embodiment that not entwei- in the open position air from the line 151 through the switch can be similar surfaces, however, air can escape from the lines, which are old connected to the switches on the side opposite the side to which the line 151 is connected. When valve 184 applies a vacuum to the corresponding opening, the ball of valve 184 moves into a position to block opening 182. If no compressed air is available to pressurize the inlet openings of valve 209, both switches 211 and 314 blow air from opening 272 to atmosphere provided switches 211 and 214 are not closed.

In Fig. 13, a transverse profile 230 is shown, the opposite Ends are supported by track parts 19 at one point on the shaft 23. The end position switches 215, 217, 225t, 180 and 177 are in crosswise direction device spaced one inside the other on the profile, with their actuators sit in such a position that they can be switched by the squat parts 234 to 238, which are attached to a shaft 23 are secured in fixed angular positions, with the help of clamping screws, not shown. The shape of the squat parts is intended to that the valves are switched in the Veise described below.

The valve member 214 sits on the profile 230 in such a position that whose switching element is actuated by the guide rod 36 to the

- 16 T 0 9 8 Λ 6/1085

Close valve su when both the guide rod is retracted All of the cylinders 27 are open. An end position vacuum switch 169 sits on block 240, which in turn is used to move with the cylinder 104 is arranged on him. The block 240 carries the switch

υ 189 at such a point that its switching element is halted by the S 241 is actuated on the piston rod 105, while eich'die The piston rod is moved towards its extended position.

The limit switch 213 is located on the V-trough conveyor in one position in the transverse direction at a distance from a sack that is moved from the magazine to the shaft, like on a Saok that falls filled onto the conveyor but he is in such a position that its spring switch arm 213a closes the switch after the conveyor has moved the sack a short distance from where the sack was gets onto the conveyor by falling off the shaft.

For the purpose of describing the operation of the inventive Apparatus assumes that there is a stack of bags 134 in the magazine is located, which bear against the wall section 133a, and accordingly the switching element 139 holds the switch 137 in the closed position. Further it is assumed that the piston rods 26 and 34 are extended and that the piston rod 103 is retracted. As a result, lie attach the suction cups to the topmost sack in the stack 134. At this time The end position brackets 217 and 177 are in closed positions (as a result of the angular position of the shaft 23), and the end position brackets 214 is in its open position as a result of the fact that the guide rod is remote from the switch. Furthermore, the switch is 189 in its open position.

Once the switch 159 is moved to its closed position, goes Compressed air through the opening 222 of the valve 220, so that the valve member 221 is held in a position in which the working cylinder 104 remains in its retracted position (or returns to it). There the limit switches 217 and 137 are in a closed position, Compressed air reaches junction 186 and goes through the throttle

- 17 1 09846/1085

Secondary point 183 and then to the opening 196 of the valve 197 »so that the valve member 198 remains in a position (or moves into it) in which the cylinder 33 is extended. In addition, pressurized air is directed from junction 186 to port 165, whereby valve member 167 remains (or migrates into) its position in which pressurized air is directed to the control port of vacuum control valve I64. This causes a vacuum to travel from the vacuum source to junction 172 and thereby to the suction cups. Furthermore, the vacuum present at junction 172 becomes effective at throttle valve 174. Since the shells are in contact with the uppermost sack, insufficient air is sucked into the shells to prevent a rapid pressure reduction at junction "172. The increasing negative pressure builds up until it is below the setpoint value for the check valve 174, and when that point is reached, the check valve allows the vacuum to travel from junction 172 to limit switch 177 and then to junction 176. The pull of the vacuum at junction I76 is sufficiently greater than that of the pressurization from port 182 to junction I76 so that the valve member 198 is pulled by the vacuum in the direction of the opening 186, whereby compressed air acts on the opening 33a in order to retract the bag pick-up mechanism. After the movement of the bag pick-up mechanism into the retracted position, the guide rod switches the end position valve switch 214 to a closed position i

If at the beginning of the retraction of the suction cups one of the cups has not gripped the sack with suction, air flows through the scarf and the corresponding line 173 to branch 172, so that the negative pressure becomes smaller at the junction 172, which has the consequence that the check valve 174 is generally pressed into a closed position. By closing the check valve 174, the pressurization of compressed air through the casing point 185 at the opening 196 builds up in one hatred enough to cause valve member 198 to become adjacent opening 199 wanders. Accordingly, the cylinder 33 is at the Compressed air is applied to the opening 35b, so that the piston rod 34

- 18 109846/1085

is extended. So the suction cups are again in the lower one Position moved to lie against the sack so that air can flow through the suction cup. can be sucked. Then the suction cups are described in the Way back. If the bowls again do not take hold of the sack with suction, the working cycle of extending is repeated and Zurttckfahren the working cylinder 33, until τοη an operator the lifting movement of the shells is ended or until all the shells grip the sack in a sealing manner.

When the sack τοη has been properly grasped in all of the bowls, nothing happens during the first work cycle of the day until either the hand is depressed to a to assume the closed position, or until the switch 211 τοη hand is pressed. Formally, the switch 211 is pressed in by hand , and this leads to the opening 206 of the Yentil member 205 »it is pressurized with compressed air in order to move it away from the opening 206, so that the opening 27b is acted upon by compressed air, to retract the piston rod 26. As a result, the cylinder 33 and the shaft 23 about the axis of rotation of the shaft 23 in the direction of arrow 450 rotated. The first few degrees in the rotation of the Such 23 lead to a movement of the misalignment yaku switch 217 into an open position and shortly thereafter also to a movement of the End position Y-valve switch 177 in an open position.

After the Tom bag pick-up mechanism grabbed the bag at an angle has been moved sufficiently about the axis of the shaft 23 so that the sack comes to the area of the sacks in the sack magazine, the Sndlagensohalter 180 switched to a closed position to the Inlet 181 and thereby the opening 196 via the junction I76 To apply compressed air so that the valve member 198 reaches its position at the opening 199. As a result, the working cylinder 33 pressurized with compressed air to the Saokaufnahmemeohanismus to move to an extended position. The end position holder 180

1 09846/1085

is only switched to its closed position during the short step of the angular movement of the shaft in the direction of arrow 450, however, when the shaft is turned in the opposite direction, it is not switched to its closed position. The working cylinder 53 is in its roll extended position before the Timer shaft 23 has been rotated sufficiently far that the Working cylinder 55 has moved into a horizontal position.

Immediately upon reaching the horizontal position of the working cylinder 35, the end position vacuum switch 215 is brought into its closed position, among other things to apply compressed air λ to the opening 219 of the valve 220. As a result, the valve member 221 moves into a position in which the working cylinder 104 * is pressurized with compressed air in order to extend it. When the working cylinder 104 is extended, one side of the sack is moved between the Saokklenme 100 and the jaw 94a, while the opposite side moves between the Saokklemme 117 and the Saoke 115. The sack clamp 99b, when it moves in the direction of a position in contact with the jaw 94, causes the jaw 115 to move the other side into a more open position and then clamp it against the sack clamp 117.

Before the piston rod 105 of the working cylinder 104 is rolled out the switch 189 is switched to a closed position, and on At the end of the extension lift switch 189 opens. Switch 189 f is provided in such a version that it can only be used during the Extension stroke of the working cylinder 104 is switched to a closed position, but not during the Bückfahrhubs.

The closing time of the switch 189 is sufficient to close the junction 190 and then to pressurize the opening 166 with compressed air to the valve member 167 to an open position, causing vacuum control valve 164 to apply vacuum from vacuum source to junction 172 interrupts. As a result of this, the suction cups released their suction adhesion to the sack, which is then fully held by the shaft 90. aside from that

109846/1085

the pressurization of junction 170 causes the Valve member 206 is brought into position at opening 206, whereby the working cylinder 27 is acted upon by compressed air in order to cause the piston rod 26 to extend. Doing so is in the opening 27a switched on a throttle as a time delay acts so that a second sack is not moved to the chute until the sack located there filled, deposited on the conveyor 12 and through it has been moved out of the path of movement of the second sack. Further the pressurization of the branch 190 leads to a pressurized air pressurization of opening 199 of valve 197 to & as valve so to actuate, since the workers' cylinder 33 is acted upon with compressed air so that the piston rod 34 is in alignment with its retracted Location is moved.

The shaft is equipped with known so-holders (not shown), which operate the cattle pouring mechanism of the shaft to fill a filling to pour, provided that both sides of the bag are properly placed are clamped to the shaft.

The initial movement of the working cylinder 27 to extend the piston rod 26 for rotating the shaft 23 by a few degrees in the opposite direction to arrow 450 results in switch 215 resiliently returning to an open position. It is also momentary through the initial movement of the shaft 23 in the direction opposite to the arrow 450, the end position valve switch 225 is switched into a closed position (the switch 225 is not switched to a closed position when the shaft 23 rotates in the direction of arrow 450), and this, in turn, operates valve 226 to pressurize lines 173 to remove dust and other foreign matter blow out the suction cup. The Sohalter 225 opens before the Time at which the working cylinder 27 reaches its fully extended position. Bfach open the switch 225 and before moving the piston rod 26 in its fully extended position becomes the end position valve switch 177 moved to a closed position. After the KoI

109846/1085

rod 26 has migrated to its fully extended position, the Limit switch 217 switched to a closed position. Closing switch 217 causes branches 166 and 216 are pressurized with compressed air, whereby the valve 220 is actuated is to pressurize the opening 104a of the cylinder 104 »with compressed air, and the vacuum control valve I64 is pressurized with compressed air, to open this valve, thereby applying vacuum to junction 172; junction I76 is also pressurized with compressed air. As a result of the pressurization of junction 176 (There is no significant pressure reduction at the check valve 174 because the bowls are at a distance from the sacks) moves' | the valve member 198 such that the opening 33t> * it pressurized air is applied so that the suction cups to rest on the second sack in the Stack on the magazine are moved,! After the work cycle continues in the previously described, except that the switch 211 need not be brought to its closed position. That exception is the Result of the fact that at the point in time at which the opening 222 of the Valve 220 is acted upon with compressed air, the working cylinder comes into a retracted position, whereby the bag from the shaft falls off. The filled sack falls onto the V-trough conveyor moved by the conveyor so that it strikes the arm 213a and thereby switches switch 213 to form a closed circuit through switches 217, 137 »213, 214 to branch 209, whereby the opening 206 is acted upon with compressed air. In this connection " a throttle point in cylinder 27 (opening 27a) is inserted, to delay the movement of the cylinder in its fully extended position so sufficiently that the bag receiving devices to Pick-up of a sack moved and withdrawn to close a switch 214 (guide rod 36), immediately before the switch 213 is closed. So the way it works is automatic.

After the last sack of the stack I34 has been removed from the magazine the so holder 137 moves to an open position to prevent the junction 212 from being pressurized with compressed air the magazine has advanced a stack of bags (stack 135) around the

- 22 109846/1085

Switch to close. Simultaneously with the opening of the holder 137 after the removal of the last sack leads to the feeling of the finger 138 the switch I36 turns on the motor 124 to the conveyor belts 126, 127 drive until the second stack of bags 1335 arrives the Vandpartie 133a is applied. The second stack of bags 135 switches When moving in contact with the wall 133 «, the switches 136 and 137 «u» Switching off the motor 124 or closing the switch 137.

The gate direction according to the invention continues with these controls automatically, as long as bags are inserted in the magazine in order to be moved to it in abutment against the wall 133a after the Switch 211 has been closed to begin lifting the first sack from the magazine at the beginning of the work day to start.

Ss should be noted that for the FaI "that the sacks in the magazine are not properly aligned or that the suction cups are not functioning properly to pick up a sack that Switch 195 is slid into position to form an air circuit of junction 155 and junction 194 zn close. Through this the valve 197 is switched to a position in which the working cylinder 33 is moved into a retracted position and in it is held (even if the connection I76 is pressurized with compressed air 1 i.e. as a result of the throttling point 185) «to the switch 195 is again moved to an open position.

Then the general mode of operation of the device according to the invention has now been described, a more detailed description of the operation of the pickup mechanism will now be given. For the purpose the description of the operation of the Saokaufnahmemeohanismus it is assumed that it is in the position shown in FIG. With the movement of the piston rod 34 in the direction of arrow 255, the suction cup 68 initially makes contact with the upper one

- 23 109846 / 108S

Sack 154a in stack 134. At the same time that the shell 68 is making the first contact, the various files of the Saok-receiving mechanism are in the Pig. 3 illustrated load layers. With the movement of the piston rod 34 and the block 35 in the direction of arrow 255, the Baag shell is prevented from moving further in the same direction, and this leads to the fact that the ir * 65 is rotated around the joint 66 in the direction opposite to the arrow 76 . The Bollen 53 thereafter dgelangen in contact with the bag 134a, and the Veiterbevegung of Slocks 35 in the calibration of the arrow 255 leads dasu that the suction cups are rotated 58 about the shaft 43 in the screening of the arrow 256, i namely against the gate voltage of the springs 50 · At the same time, the sole parts 58a come into contact with the sack. As a result of the resilience of the shells, the block 55 can move further in the direction of the arrow 255, which means that the separating rod is rotated around the shaft 45 in the direction of the arrow 257 in order to tension the torsion springs 81 below after contact with the bag, the influx of air into the bowls, and this leads to a retraction of the piston rod 34 via the controls described above. like that shown in FIG.

laughing when the bowls take hold of the sack, the distance is the Saugsohalen 68b opposite the suction cups 58 * i »is essentially fixed, i.e. apart from τοη the yield of the shells and τοη a slight relative movement made possible by the springs 56 will. During the beginning of the retraction of the trays, the spring 71 pushes the rod 70 around the hinge 67 in the direction of the arrow 260, whereby the arm 65 rotates about the joint 66 in the direction of the arrow 76 will. The torsion springs press the separating rod around the shaft 43 in the direction opposite to the arrow 257. They spring 50 presses the suction cups 58 around the shaft 45 in opposite directions to arrow 256. As a result, the sack moves a little

109846 / 1OdS

in the direction of the arrows 265 opposite the block 35 (Fig. θ), and the part of the gripped side of the bag wipe the suction cup 66 and the separating rod is held in one plane while the part between the separating rod and the suction cups 58 eo is moved, Dafi it extends at an angle to the first-mentioned rope the side of the bag, as shown in Fig. 6 for the ^number k * ⁿ of the e Büokfahrbewegung the piston rod is geaeigt 34th Since the opposite side is not gripped, the second named part of the side of the sack is pulled away from the second side of the sack, and it is in a position as shown in fig. 9 is shown after the sack has been removed from the magazine. As a result, the Saok is first opened in the area of the bag opening (Fig. 10). In this context, it should be noted that the suction cups, for example, take a 50 kg Saok about 50 mm away from the tape, which partly forms the opening of the sack. The sack pick-up mechanism moves the two parts of one side relative to the other, not gripped side, in order to partially open the opening of the sack sufficiently that the chute jaws can spread into it while the sack is swung towards the chute, as has been described, wherein the opening of the sack is partially opened while the piston rod 34 is moving backwards in the direction opposite to the arrow 255, while the piston rod is at the same time in an extended position.

It should be mentioned that with the beginning of the movement of the blook 35 the Saokaufnahmellage shown in Fig. 1 (opposite direction to arrow 255) the leaf spring is opposite the shaft 4? in respect rotates opposite to arrow 256, the leaf springs moving out of contact with the bearings 62 and thus the suction cups 58 can be printed resiliently in layers that are further spaced apart in the transverse direction. As a result, any wrinkles in the skin are seized Part of the side of the bag between the cups 58 removed. For example, the suction cups 58 can expand by approximately 6 mm move away from each other while the leaf springs opposite the load

like to move from the bag receiving position according to FIG. 5 to their end position, in which the rod 51 strikes the pin 49 (if no sack is held by the shells).

Simultaneously with the release of the vacuum, the trays and the separation bar return to their reference positions opposite block 35, the reference positions opposite block 35 being shown in FIGS. The spring 50 thus pivots the shells 58 in the opposite direction to the arrow 256 until the rod 49 strikes the arm 51) the spring 71 pivots the rods 65 around the joint 66 in the direction of the arrow 76 until the stop 74 strikes the block 35, and the suction cup 68 · i pivoted about the hinge 67 in Riohtung opposite to arrow 260 until the spring 71 extends in a straight line between the hinge 67 and the connection of the spring to the bracket 12; and the separating rod 85 is pivoted about the shaft 43 in the direction opposite to arrow 257 in order to release the tension in the Toreion springs.

Through the use of the separating rod and the storage of the suction cups, the opening of the sack is only opened by that a page 134aa of the SLeks is gripped without the use separate devices takes place, for example an Luftslaseinriohtung or suction cups to grab the other side. Furthermore, in the device according to the invention, the stokes are not at the end " stacked, but tilted at an angle, what their holding in alignment with the other supported, being as an angle of inclination 20 to 30 ° compared to the Vaagrechte are possible.

It should be mentioned that the upper Saugaohalea are those who dea Grasp the sack immediately in ithe of the mouth of the sack while the lower shell is the one that has the sack at a greater distance from the mouth of the sack as the upper shells are gripped. References to the "upper" and "lower" shells refer to see so not necessarily on the relative heights of the sohales.
