Definitions

  • Production machines for envelopes, mailers and similar products made from paper and / or plastic webs work continuously over several hours during a work shift. At the end of the production machine, the products have to be counted packed in containers, in particular in cartons, and the filled containers either transported individually or stacked on pallets. This packaging is still carried out by hand on many production machines. Because of the continuous operation, two people are generally required as packers at the delivery point so that they can represent each other if necessary. While one of these two people is working at the packing table, the other person can only carry out auxiliary services.
  • a packaging machine for mechanically packing the envelopes or mailing bags. This is installed at the end of the relevant production machine immediately after the serrated lock washers of the production machine. With this automatic packaging machine, the packaged goods are delivered in the form of envelopes or mailing bags from the serrated lock washers via a guide plate to two storage belts which are arranged parallel to one another. The storage belts are guided around a pulley on two parallel shafts, one of which is driven. A stack support is arranged above the level of the storage belts and is movably guided in the longitudinal direction of the storage belts by means of a longitudinal guide. The individual pieces of the packaged goods are placed against the stacking support by the serrated lock washers of the production machine. This stack support is moved away from the serrated lock washers by a drive with the packaged goods.
  • a separating device In the area of the serrated lock washers there is a separating device, by means of which a stack of a certain number of individual pieces of the packaged goods can be separated from the subsequent packaged goods, a gap being simultaneously formed between the stack and the subsequent packaged goods.
  • This separating device has a separating fork, which rises in the area of the serrated lock washers from below the support plane of the storage belts into the gap between two individual pieces still in the slots of the serrated lock washer and thereby enables separation.
  • This separating fork is guided parallel to itself by means of a parallel crank mechanism and moved on a circular path, as a result of which it moves with the goods to be packaged over a short distance.
  • the separating fork is arranged in the area of the serrated lock washers so that it can engage in the space between two individual pieces of the goods to be packaged which are still kept separate from one another in the slots of the serrated lock washer, and in that, owing to their circular movement path, they have only a limited distance with the Individual pieces can migrate and thus only a relatively small number of individual pieces can be accommodated between it and the serrated lock washers, the stack separated by the separating fork must be brought out of the path of movement of the subsequent packaged goods as quickly as possible so that the stack support is again in front of the front of the subsequent packaged goods can be brought into their supporting position so that they can take over the support of the packaged goods before the separating fork is immersed too far.
  • a transfer device above the Storage belts is arranged. It detects the stack separated from the subsequent packaged goods and brings it to a transfer position, where the stack is pushed down into an open carton.
  • the transfer device has two transport forks which are arranged one behind the other to form a carriage in the direction of the conveying movement of the packaged goods.
  • One transport fork is rigidly arranged in the direction of movement of the packaged goods at the end of the carriage.
  • the second transport fork is connected to the carriage by means of a vertical lifting device. This is movably guided on a horizontal longitudinal guide of the carriage relative to the first transport fork and coupled to a drive.
  • the carriage of the transfer device is movably guided on the horizontal longitudinal guides from the transfer point to the transfer point. It is moved back and forth between the transfer position and the transfer position by means of a chain drive.
  • the stack is gripped by the transfer device in such a way that the stack support is laterally withdrawn from the path of movement of the stack after the rigid transport fork has been reached, as a result of which the stack lies against the rigid transport fork.
  • the stack support is moved back to its starting position near the serrated lock washers.
  • the movable transport fork is lowered into the gap between the stack and the packaged goods by means of the lifting device and is moved to a certain extent against the rigid transport fork by the horizontal drive.
  • the stack located between the two transport forks is compressed and clamped between the transport forks. In this state, the stack is conveyed from the transfer device to the filling station.
  • the stack support is again pushed transversely into the path of movement of the following stacked goods.
  • the stack held by the transport forks partly rests on floor plates that are shorter than the stack length. These floor plates can be folded down from the horizontal position into a vertically downward position by a pivot axis that is aligned horizontally and at the same time transversely to the movement path of the stack.
  • a box with an open flap is generally lifted from below into the filling station. Then the bottom plates are folded down into the box so that they can serve as guides for the stack.
  • the stack which is still held by the transport forks, is pressed downwards out of the transport forks into the carton by a vertically guided and driven rake.
  • the transfer device then moves the two transport forks back to the takeover position.
  • the movable transport fork is raised beforehand so that it can be guided over the newly formed stack. As soon as the gap is created at the end of the next stack, the movable transport fork is lowered into this gap, after which the next work cycle follows.
  • the outer two fork tines of both transport forks must be set exactly to the new format width.
  • the position of the box must be set to the format width.
  • both the forward and backward movement of the stack support must be set accordingly.
  • the distance between the two transport forks and each other and relative to the degree of compaction must be set, the latter depending not only on the stack length but also on the paper thickness, the paper quality and the design of the envelopes or mailers.
  • the carton must also be adjusted to the changed stack length, provided the travel distance of the transport forks remains the same, in relation to the movable transport forks.
  • the floor plates in the filling station As far as the folding axis of the floor plates in the filling station is aligned parallel to the direction of movement of the stack, the floor plates have to be exchanged if the length of the stack is greater because they cannot be lengthened or shortened by themselves. The same applies to a change in the width of the format, provided that the swivel axes of the base plates are aligned transversely to the direction of movement of the stack. Either there must be several groups of floor plates for this, or you are narrowly restricted in changing the format.
  • a major disadvantage of this automatic packaging machine is that the stack is clamped in the filling station between the two transport forks as a free carrier, at the latest from the point in time at which the base plates were folded down.
  • those surface areas which, due to the greater number of paper layers lying one above the other, are most likely to absorb the compressive forces of the two transport forks in the stack, are distributed in very different ways over the end face of the stack.
  • the phenomena of the buckling bar occur with eccentric loading or, conversely, with central loading and eccentric cross-section.
  • the surface area of the stack which transmits the compressive force of the transport forks is located at the bottom, the upper surface areas being able to contribute nothing to the support of the inner bending moment due to the smaller number of paper layers.
  • Such a carrier which is only clamped at the two ends, breaks all too easily under its own weight in the middle. This means that the moment the bottom flaps are folded down into the box, the carrier made of the individual pieces bends downwards in the middle and suddenly breaks down after a little sag, before the side ones Edges of the stack could be pushed down by the rake.
  • Such a broken-through stack can at best still be arranged with laborious manual labor and squeezed into the carton with equally laborious manual labor.
  • the invention is based on the object of specifying a method with which a packaged item in the form of envelopes, mailing bags or the like can be automatically packaged in containers with a higher level of operational safety than in the known method.
  • the invention has for its object to provide suitable packaging machines for performing the method.
  • the goods to be packaged are first conveyed away from the production machine by means of the storage belts and the stack to be packaged is only separated from the subsequent goods to be packaged at some distance from the serrated disks of the production machine, this results between the separation point and the serrated lock washers have a relatively large storage space with a correspondingly large number of individual items of the packaging material.
  • This large length section of the relatively loosely conveyed to the separation point packaged has such a great compressibility that there is enough time behind the separation point to cross the sectioned stack to push the original direction of movement into the container and to return the devices involved back to their starting position for taking over the next stack, the separating point not having to travel with the packaged goods, as is the case with the known packaging machines.
  • the entire subsequent packaged goods can be stopped using their compressibility until the divided stack has been pushed into the container and the devices involved have returned to their starting position. Because the separated stack is slid horizontally into the container on a slideway, it does not have to be clamped and raised and transported freely. As a result, the inevitable inhomogeneities in the stack no longer have an adverse influence on the operating sequence of the packaging machine and thus indirectly on that of the production machine.
  • the separating point are separated from the subsequent packaging and they are moved from this point transversely to their original conveying movement and both the separating device and the slideway always occupy the same position, only the stack support in its normal direction of movement has to be changed if the format is changed or are moved less far from the separation point and the pushing is done more or less far.
  • the container can be aligned in all formats to the unchangeable level of the slideway and the separating device.
  • the same or at least similar conditions are present, only the formation of the gap for inserting the separating part takes place in that the separating part first moves into the gap in a first stage of its movement, which is caused by the partial pushing out of the Counter piece was formed on the other side.
  • the individual pieces of the packaging material adjoining the primary gap are temporarily stopped again until a sufficiently large secondary gap has formed between them and the preceding stack, into which the separating part can be completely inserted in order to completely separate the stack from the packaging material that follows.
  • the stack is separated from the subsequent packaging material without the presence of a physically detectable counting piece in that the separating part separates the visually imperceptible and only numerically present counting piece and the adjacent individual piece from one another with an eccentrically rotating tip, that one of these two individual pieces bounces off this tip elastically when it hits the rotating tip and thereby the tip has the opportunity to penetrate between these two individual pieces and as a result of the further rotation and further advancement
  • the entire width of the stack is separated from the subsequent packaged goods. This is followed by pushing over the separated stack in the same way as in the other methods, the compressibility of the packaged goods being used for the timing of these processes.
  • this method By designing this method according to claim 4, the individual pieces of the stack are shaken and, as a result of the abutment of their one side edge, aligned flush with the sliding part. As a result, the individual pieces in the container no longer have to be adjusted in order to be able to close the container and also to achieve a pleasing appearance of the stack in the container. If this method step is further developed according to claim 5, the alignment of the individual pieces in the stack is additionally facilitated due to the then lower mutual contact force of the individual pieces. An embodiment of the method according to claim 6 ensures that the stack is inserted into the interior of the container, thus practically eliminating the risk of bumping or rubbing against the container walls.
  • the drive of the storage belts takes place continuously and not in batches, and in that the drive also on the actual feeding speed of the individual pieces coordinated, with failures in the production machine also being taken into account, there is no compression or thinning in the packaged goods.
  • the fact that the stack support is guided on its own guide and it has its own drive means that in this area of the packaging machine changes to other formats are possible without difficulty, both with regard to the dimensions of the individual pieces and with regard to the type of fold and with regard to the material qualities.
  • the stack support has two or more strip-shaped support elements one above the other, which are aligned horizontally, an at least approximately vertical guidance of the packaging material is made possible in its entire height.
  • the separating device is arranged at a certain distance from the serrated lock washers of the production machine, there is a sufficiently large storage space with such a great compressibility of the packaging material therein that for separating the stack, for pushing it into the container and for that Returning all devices involved in their initial position, sufficient time remains.
  • the separating device has a separating sword with a wedge-shaped head and with an adjoining shaft, the total length of which is at least equal to the greatest possible width of the packaged goods, and in that the separating sword is guided on a guide transverse to the movement path of the packaged goods and is coupled to a drive , it can stack the stack to be packed on its whole Separate the width and the entire height of the following packaged goods.
  • the separating sword is arranged in its rest position so that the tip of his head at least partially protrudes into the movement path of the counting piece, and in that in this area the tip of the separating sword there is at least one sensor which is used when approaching and / or emits a control signal when the meter at the tip, and because a delay element is switched on in the control of the drive, it is possible to detect the arrival of the meter at the point of separation by delaying the activation of the drive of the knife at the meter and temporarily stopping the immediately following individual pieces while the remaining part of these individual pieces is being pushed through the subsequent packaged goods, and in this way to create a larger gap between the counting piece and the preceding individual pieces, into which the separating sword with its wedge-shaped head and on then continues his g the entire shaft can be pushed in until the stack is completely separated from the subsequent packaged goods.
  • the transfer device is designed as a shifting device which has a shifting rake, the tines of which extend above or below the horizontal support elements of the stacking support up to at least the separating sword, and in that the shifting rake is displaceably guided transversely to the movement path of the packaged goods by means of a longitudinal guide is and is coupled to a drive, the separated stack can be moved laterally at a constant height into the container without the stack being gripped and clamped by a gripping device and possibly also having to be transported freely.
  • This horizontal sliding displacement of the stack on a fixed slideway between the two Through guide elements the stack can be pushed into the container without any difficulties. For example, neither a different distribution of the number of layers of paper nor different properties of the material of the individual pieces can cause disruptions in the operating sequence. The stack cannot break through, as can occur in the known packaging machine.
  • the sensor at the top of the separating sword responds not to the installation of a counter piece pushed out of the packaged goods, but to the gap of the counter piece pushed out to the other side and emits a control signal, and that the retracting movement of the separating sword takes place in two stages, in which, at the first stage of its entry movement, it only moves into the primary formed by the pushed-out counting piece, thereby temporarily stopping the subsequent individual pieces, and only after the formation of a sufficiently large secondary gap between the counting piece and the subsequent pieces Single pieces into it and through the packaged goods.
  • the devices are also identical or largely similar to those of the automatic packaging machine according to claim 7.
  • the packaging machine according to claim 9 only the separating device is modified more, because there are no counting pieces which are pushed out or out by a certain distance to one side or the other and which are thereby visually detectable. With him the counting piece is merely a numerically recorded single piece, in which the separation process is carried out.
  • this separating device has an eccentrically rotating cone tip, which is moved against the goods to be packaged when the counting piece arrives at the separating point, it can happen that it either encounters a gap between the counting piece and one of the adjacent individual pieces or that it counts the counting piece or touches the one-off piece on one side or the other and compresses it slightly elastically. In the latter case, the continuous eccentric rotational movement and the further advancement of the cone tip and by moving the packaged goods transversely to the direction of approach of the cone tip will cause the individual piece to jump off the cone tip on which the cone tip first hit.
  • the tip of the cone is already between this single piece and the adjacent single piece, and as a result of the further advancement with a simultaneous eccentric rotary movement, it constantly increases the gap into which the entire separating lance then enters.
  • the other processes are the same as for the other two packaging machines.
  • the individual pieces of the packaging material brought up are deposited directly on the storage belts by the serrated lockers, the detached individual piece on the preceding single piece is not yet present and it can therefore not be prevented by this by frictional engagement on the storage belts.
  • the individual pieces of the packaged goods are aligned flush with each other from the start.
  • the stack support with its longitudinal guide and the separating device and the transfer device can be separated from the table frame with the storage belts and from a production machine to another production machine, which also has a table frame with storage belts of the same or similar type.
  • the packaging machine in particular when the stacking support is equipped with two sensors at different heights, it is possible to determine whether the goods to be packaged are so close to the stacking support that they rest equally against the stacking support both below and above or whether the foremost single piece has a certain distance from the top or bottom of the stacking support because, depending on the position of the surface areas with the largest number of paper layers, it is inclined with the upper edge first or vice versa with the lower edge first and the other edge around one a certain distance back.
  • the speed of movement of the stacking support can be adjusted such that the foremost single piece of the packaged goods is aligned perpendicularly and thus parallel to the other individual pieces of the packaged goods.
  • the packaged goods are conveyed largely uniformly.
  • the fact that the wheel resting on one of the storage belts and rotatably mounted ensures that when the storage belts move relative to the friction wheel, the friction wheel is rotated relative to its bearing axis.
  • the friction wheel is connected to a control disk in the form of a cam disk, which cooperates with a pushbutton switch that converts a rotary movement of the control disk into corresponding control signals, a further control option is achieved with which the stack support is evenly uniform, albeit at small intervals is moved on with the conveyed packaging goods.
  • the longitudinal grooves on the side of the separating sword facing the stack support ensure that the tines of the sliding rake can extend into these longitudinal grooves of the separating sword, so that the rear individual piece of the separated stack can also be removed from the tines of the sliding rake is detected, so that it cannot remain behind despite the friction on the separating sword, but is reliably moved together with the other individual pieces of the stack into the container.
  • An embodiment of the packaging machine according to claim 16 ensures that the separating sword is first introduced into and through the gap like a compact separating body with a small vertical dimension along the lower edge of the packaged goods, with the alignment of the individual pieces above the gap being practically insignificant has, that is that a slight inclination of the individual pieces can be accepted. Only after the separating sword has been completely retracted will the upper one Moving parts of the separating sword raised in its operating position, the possibly not exactly vertical individual pieces are aligned vertically on both sides of the gap, so that in particular the rear single piece of the stack has the required vertical alignment for a correct insertion into the container.
  • the guide elements of the stack support and the separating sword or the separating lance can have dimensions that are slightly larger than the greatest possible width of the stack.
  • the intermediate space is bridged almost to the bottom of the container by the further guide elements in the line of alignment of the guide elements of the stack support and the separating sword or the separating lance.
  • at least one group of the other guide elements is pivotally mounted about a common vertically aligned pivot axis and it is under the action of a spring member, through which they can be pivoted slightly to the interior of the container, the container can be easily accessed from the outside Slide on other guide elements.
  • the stack is shaken at the beginning of its sliding movement, whereby the frictional engagement between the individual pieces lying against one another is significantly reduced.
  • the shifting rake with its prongs which moves in the direction of the container, ensures a flush alignment of the edge of the individual pieces of the stack lying against it, including the counting piece which originally protrudes noticeably towards the other side.
  • the individual pieces of the stack have a pleasing flush alignment even in the container.
  • the shaft of the separating lance can be fastened directly to a slide or carriage, by means of which the separating lance is displaceably or displaceably guided on the longitudinal guide, avoiding a rotary bearing.
  • the tapered head is rotatably mounted on the shaft or better still in the longitudinal through hole of the shaft, the drive shaft only has to transmit the very small torques for the rotary movement of the tapered head. It can therefore be made relatively thin, so that it takes up little space on or in the shaft.
  • the packaging machine according to claim 21 can also in the A lance of the sliding rake grips into the groove of the shaft so that the last individual piece of the stack is securely grasped when moving.
  • this automatic packaging machine enables the stack to be separated from the subsequent packaging goods even under unfavorable circumstances in the same flawless manner as is possible with the automatic packaging machine with the separating sword designed according to claim 16.
  • starting or starting up the packaging machine together with starting up the production machine is made easier because the start support of the packaging item is also supported and held in a vertical orientation when the beginning of the packaging item is the separation point has not yet reached the point at which it is taken over and supported by the stack support.
  • the temporary use of the start-up support is not only considered if the production machine has been converted to a new format for the packaged goods and thus restarted, but also if the production machine is restarted due to production disruptions in the production machine or in the event of routine operational interruptions and from the previous one Operating time is no longer sufficient individual pieces between the serrated lock washers and the stack support or if a larger number of individual pieces have been removed from the packaged goods, for whatever reason.

  • the support body 136 is arranged on two spacers 118, via which it is connected to the holding head of the separating device.
  • the shaft 134 can have any cross section, for example a square or rectangular cross section (FIG. 26). It is therefore designed as a hollow body and has a through hole 137 running centrally to its longitudinal axis. At the two ends of the shaft 134 two bearings 138 are arranged centrally to the through hole 137. A shaft 139 is mounted thereon, at the front end of which the conical head 135 is arranged. At the opposite end, the shaft 139 is coupled to a rotary drive attached to the support body 136, which is not shown in FIG. 25. At the end region adjacent to the cone head 135, the outside of the shaft 134 is aligned with the circular cylindrical end region of the cone head 135 in order to avoid end faces against which the packaged goods could touch.
  • the shaft 134 In the event that the horizontally measured outer dimension of the cross section of the shaft 134 is only slightly larger than the inner dimension of the through hole 137, it is expedient to provide the shaft 134 on the underside with a keel-like extension 141, which is indicated by dash-dotted lines in FIG. 26 .
  • this extension 141 In the area of this extension 141 there can be a longitudinal groove 142 on the side facing the sliding rake (FIG. 20), on which a tine of the sliding rake 132 can be aligned such that its free end extends into the upright projection of the groove 142.
  • the separating lance 113 can also be provided with an upper part 143, which can also have a longitudinal groove 144, to which a tine of the sliding rake 132 is aligned when the upper part is in the raised operating position.
  • the upper part 143 is connected to a lifting device, which the spacers 118 serve as a longitudinal guide.
  • the handling device 8 has two conveyor belts 145 and 146.
  • the conveyor belt 145 is used to feed the empty containers 9 to a transfer device 147.
  • the conveyor belt 146 is used to remove the filled containers 9 from the transfer device 147 (FIGS. 33 and 34) to a stacking station or to a further conveyor device.
  • the two conveyor belts 145 and 146 end shortly before the floor plan area of the last of the empty containers 9 being conveyed above the transfer device 147 (FIG. 27).
  • a stop plate 149 is arranged in the path of movement of the containers 9, which is oriented perpendicularly and which the container 148 later also during the lowering movement as Leadership serves.
  • the stop plate 149 is fixedly arranged in the conveying direction of the conveyor belt 145, so that the side wall of the containers 9 facing the production machine 2 is always set on the alignment line of the separating device 5.
  • the transfer device 147 includes a vertical conveyor 151, which has a pneumatic piston drive 152 with a piston rod 153, on the upper end of which a suction head 154 is arranged.
  • the conveying height of the vertical conveyor 151 corresponds to the height difference between the upper conveyor belt 145 and the lower conveyor belt 146.
  • the sag head 154 can be connected to a vacuum generator via the piston rod 153.
  • a sliding table 155 is arranged at the level of the conveyor belt 146. It can be moved horizontally on a longitudinal guide with two guide rods 156, the direction of movement of the sliding table 155 being aligned parallel to the line of alignment of the guide strips 91 and the support elements 51 (FIG. 15).
  • the table top 157 of the sliding table 155 has on the side facing away from the packaging machine a cutout 158 with a U-shaped plan figure, which is open towards the side facing away from the packaging machine.
  • the plan area of the recess 158 is slightly larger than the relative range of movement of the vertical conveyor 151, which results from the fact that the sliding table 155 is moved relative to the vertical conveyor 151 into the take-over position for the container 148 shown in FIG. 28, in which the vertical conveyor 151 at least stands approximately in the geometric center of the sliding table 155.
  • the sliding table 155 has a suction cup 159 in the area facing the packaging machine, which is arranged on the line of symmetry of the sliding table 155, which is aligned with the recess 158.
  • a modified conversion device 147vorraum can also be used, the parts of which are distinguished below from the corresponding parts of the conversion device 147 by reference numerals with an apostrophe.
  • the parts of the transfer device 147 ⁇ are not shown separately. In the context of the following explanations, they are designed and arranged identically or at least similarly to the corresponding parts of the transfer device 147.
  • the vertical conveyor 151 ⁇ is not arranged in a fixed location, but is combined with the sliding table 155, which only has a circular recess for the vertical conveyor 151 ⁇ in its table top 157 ⁇ .
  • the second suction head 159 ⁇ is combined with the suction head 154 ⁇ of the vertical conveyor 151 ⁇ to form a double suction head which is arranged on the piston rod 153 ⁇ of the vertical conveyor 151 ⁇ .
  • the container 148 is no longer released from the vertical conveyor 151 ⁇ after being placed on the sliding table 155 ⁇ , but held by the double suction head 154 ⁇ / 159 ⁇ continuously during the subsequent operations until the sliding table 155 ⁇ has returned to its initial position and thus the container 148 has arrived at the transfer point to the lower conveyor belt 146.
  • the container can be pushed over to the conveyor belt 146 ⁇ by the shifting device 161ieb.
  • a displacement device 161 is arranged on the side facing away from the conveyor belt 146. It has a pneumatic piston drive 152, on the piston rod of which a sliding plate 163 is attached.
  • the displacement device is arranged at least approximately in the longitudinal center line of the conveyor belt 146 and is aligned thereto.
  • the displacement plate 163 is oriented transversely to it.
  • the displacement device 161 is at least approximately open aligned the lower region of the containers 9 resting on the sliding table 155.
  • the displacement path of the displacement device 161 extends at least up to the conveyor belt 146.
  • the piston rod 153 is raised up to the container 148, so that the suction head 154 lies against the bottom of the container 148.
  • the suction head 154 is connected to the vacuum generator via a valve actuated by the control circuit. Due to the resulting pressure difference between the top and the bottom of its bottom, the container 148 is pressed onto the suction head 154, to a certain extent sucked in by it.
  • the piston rod 153 is retracted downward, thereby lowering the container 148 onto the sliding table 155 (FIG. 30) in the take-over position.
  • the suction cup 159 on the sliding table 155 is now also connected by the control circuit via a valve to the vacuum generator, after which the suction head 154 on the piston rod 153 is switched off again shortly thereafter.
  • the container 148 is held on the sliding table 155.
  • the sliding table 155 with the container 148 is shifted towards the packaging machine into the filling position, which it has not quite reached in Fig. 16 and Fig. 17.
  • the stack 12 guided by guide strips 91 and the support strips 51 is pushed completely into the container 148 (FIG. 32) and then the container 148 together with the sliding table 155 is pushed back until the guide strips 91 and the support strips 51 are complete have emerged from the filled container 148.
  • the sliding table 155 is not by one longitudinal drive shown pushed back into the takeover position (Fig. 28 and Fig. 34).
  • the suction cup 159 is switched off and the filled container 148 is pushed down from the sliding table 155 by means of the displacement device 161 and pushed onto the conveyor belt 146 (FIGS. 33 and 34).
  • the container 148 can be provided for the take-over by the vertical conveyor 151 in that the conveyor belt 145 is switched on whenever the suction head 154 of the vertical conveyor 151 is in the raised take-over position, which is shown in FIG. 27. Then the suction head 154 also serves as a support for the container 148. However, it is better to provide a transfer device 165 which is shown only in FIG. 31 for the sake of clarity. It has a piston drive 166, which is arranged in the direction of the movement path of the containers 9 lying on the conveyor belt 145 beyond the stop plate 149 and whose piston rod 147 extends through a recess in the stop plate 149 to the conveyor belt 145. A suction head 168 is arranged at the end of the piston rod 167.
