Description

The present invention relates to a supply for thermoforming machine under various aspects of its structural design.

Thermoforming machines or blister machines, in particular in the pharmaceutical sector, are used to package products singly, for which purpose a thermoforming machine is withdrawn from a supply roll and fed to a heating station, in which the forming film is heated to deformation temperature, in order subsequently to be in a forming station in the forming film To be able to train bowls, which are provided for receiving the products kept ready as bulk material. In this case, the wells are formed in the mold film usually in a matrix or grid-like arrangement, which are subsequently filled in order to then cover the mold film with the filled wells by a sealing film and hermetically seal. For the sake of completeness, it is mentioned that a thermoforming machine following the sealing station usually has a punching station in which the filled blister packs be punched out with the cups. The performance of a thermoforming machine also depends crucially on the fact that the wells formed in the forming film can be filled sufficiently quickly, adapted to the performance of the other stations, to which feeders have been developed in order to allow the simultaneous filling of several wells simultaneously.

From the prior art, in particular for obvious prior uses of Aylward Enterprises, Inc., USA, it is known to fill the wells of the conveyor conveyed by the filling station by means of such feeders in a filling station in a thermoforming machine. The arrangement of the filling tubes associated with the cups must be precisely adapted to the arrangement of the wells in the band, so that the small parts can be placed precisely in the wells. Therefore, it is necessary to remove and clean the Füllröhrchenträger with the filling tube in a format change or filling of other products, including the filling tubes are separated from the Füllröhrchenträger to remove even the smallest residues, as required in particular when the Small parts are formed by pharmaceutical products in which no residues may remain on the filling tube and the Füllröhrchenträger.

For the simultaneous filling of several wells, a plurality of filling tubes are generally associated with a plurality of channels, which are combined in a filling shoe, of which in turn several filling shoes are combined to form a filling shoe unit, which forms part of the laying unit. This filling shoe unit can be lowered vertically to deposit the small parts and lifted again after the deposit so as to allow the film to be filled or filled to pass through without any problems. So that only one product from a filling tube in the associated channel are issued, Absperrfinger be used by the bottom product can be released by the forming in the filling tube stacks each. Decisive for the feeding performance of the feeder is the filling of the filling tube, which must always be guaranteed, and indeed for all filling tubes, which in turn requires that on the entire surface of the sorting plate, this can pass the products evenly to the filling tubes.

In conventional blister machine feeds, for the filling of the cups, a format unit comprises a sorter plate and a gate valve unit, the sorter plate being suspended elastically via buffers, and vibrating the sorter plate via vibrators disposed on the sorter plate. The conventional arrangement has the disadvantage that due to the elastic support, an exact arrangement of the sorting plate to the filling tube of Absperrschiebereinheit is difficult to achieve and the demands on the manufacturing tolerances are high.

In previously known feeds with sorting plates, these openings has, in which protrude the upper ends of the filling tube. The sorting plate is peripherally equipped so that products to be fed can be filled like in a flat bottomed dish with the sorter plate moved vertically up and down to change the position of the upper stuffing tube ends relative to the bottom of the sorting plate and that Sorting out the products to promote the stuffing tubes. This is supported by additional drives associated with the sorting plate, which move the products on the sorting plate in the form of microwaves, which also promotes the homogeneous distribution of the products on the sorting plate.

With such feeders, however, some disadvantages are associated with regard to the movement pattern of the sorting plates, since the vertical movement of the microplate sorting plate loosens the product carpet formed by the products on the sorting plate, but can not uniformly distribute the products over the surface. In particular, at the edges and in the corners of the sorter plate often missing products, so that the filling tubes located there can not be filled reliably, whereby a limitation of the power is given. This can be compensated only conditionally that the amount of products is increased on the sorting plate, as this is indeed in the disadvantaged areas a sufficient amount is available, in turn, but in the center of the sorting plate accumulations form, the products when entering in hinder the filling tubes.

With regard to the micro-generating motion imposed on the sorter plate, it should be noted that this is usually associated with resilient storage of the sorter plate on buffers, the micro-wakes being generated by vibrators which, in conjunction with the storage of the sorter plate, result in circular movement of the product carpet in which there is hardly any displacement of the products in the center and in the corners. Depending on the configuration of the format with filling tubes, individual natural frequencies and thus self-forms of the sorting plates result, which lead to dead zones in terms of vibration, in which the products hardly move. To excite the sorting plates usually pneumatic piston vibrators are used, which are characterized by compact design. The disadvantage, however, is that several such pneumatic piston vibrators are required, which are to be arranged at different positions. By storing the sorting plate on buffers and the design of the pneumatic piston vibrators is an exact Synchronization not possible and a reproducibility of the product distribution is not guaranteed.

When supplied with a base unit and a gate valve unit having slide guides and gate valves movable in the slide guides, it is advantageous if, for maintenance or cleaning, the gate valve unit is detachably connected to the base unit. In conventional feeders this is effected by attached to the base unit ram, wherein the gate valves are pressed by spring elements on the plunger. The feed takes place with the aid of a single-acting pneumatic cylinder, which works against the spring elements and thereby clamps them. The return stroke takes place exclusively by means of the spring elements. In the conventional feeders, the spring elements are mounted on both sides of the gate valve unit to ensure a smooth stroke.

When dismantling the conventional feeders for cleaning and / or maintenance purposes, the gate valve unit must be removed with the gate valves. To prevent them from being pushed unintentionally by the spring force from the lateral guides, a lock is required. If this lock is released, the gate valves can be removed, it should be noted that during disassembly thereby loosely arranged spring elements are not lost.

Furthermore, the conventional feeders have the disadvantage that due to the many mechanical small parts that are used for releasably connecting the gate valve unit with the base unit and the Movement transfer from the base unit on the gate valve unit are required, the production of the known feeds is complex.

A format unit comprises the sorting plate, the gate valve unit with filling tubes and filling shoes, which can be selected according to the goods to be supplied and sorted. In a conventional feeder, the format unit is suspended via a suspension device on the base unit for securing against displacements, wherein the determination is conventionally carried out by hand via cross handles and a terminal block. This finding has the disadvantages that the cross handles are not easily accessible and in the determination of many items are necessary, which can be lost when changing the format unit. In addition, the cleaning of the base unit and the format unit is difficult due to the additional edges.

Conventional Absperrschiebereinheiten, have a filling tube corresponding number of Absperrfingern, each associated with the respective filling tube, and a base plate having a number of through holes, wherein the base plate has receptacles for Absperrfinger. In the conventional Absperrschiebereinheiten the recordings for the Absperrfinger be milled onto the surface of the base plate, since the recordings are not designed through the base plate throughout to secure the Absperrfinger.

This leads to the one hand in the production of these Absperrschiebereinheiten to the disadvantage that due to the very small geometric shapes and the large number of shots for the production of a long machine running time is required. On the other hand, this leads to the disadvantage in the handling of Absperrschiebereinheiten to the disadvantage that their cleaning is very complex because of the images, because the recordings on the top of the base plate are introduced. Due to their geometry, the corners of these recordings can only be cleaned insufficiently, so that residues can remain in the base plate.

Conventionally, an external control cabinet is used in a feeder due to the dust load and corresponding requirements. The feeder is arranged on a machine table of the blister machine, wherein the control cabinet is provided next to the blister machine.

This arrangement has the disadvantage that the electrical lines must be individually led into the cabinet because only there the motors and sensors are connected to the controller. The electrical lines are located on the filling line, where they can be contaminated with pore dust, whereby an increased cleaning effort is necessary. Furthermore, the external cabinet needs an extra space next to the blister machine and may possibly adjust access for better operability of the blister machine.

The invention is therefore based on the object to provide a feeder that overcomes the above-mentioned disadvantages of the known feeders.

According to a first aspect of the present invention, a desired arrangement of the sorting plate to the filling tube of Absperrschiebereinheit should be easier to achieve and the demands on the manufacturing tolerances can be lowered.

This aspect is included in a feed with a base unit and a sorting plate and a gate valve unit Format unit, achieved in that the base unit has a first Einhängevorrichtung for the sorting plate and a second Einhängevorrichtung for Absperrschiebereinheit, wherein on the base unit at least one adjusting device for a relative adjustment of the first suspension device to the second suspension device is arranged. As a result, manufacturing tolerances can be compensated by means of a simple relative mechanical adjustment of the suspension devices, and the sorting plate and the filling tubes can be matched very precisely to one another. In this way, it can be ensured that the shut-off slide unit with the filling tube is placed exactly centrically in the openings provided for it in the sorting plate, whereby the method steps of sorting are optimally designed. Another advantage is that the mounting of different format units at different feeds can be made the same, so that the maintenance and retrofitting with other format units are simplified.

According to one embodiment, the adjusting device is associated with the first suspension device. Alternatively and / or additionally, the adjusting device can be assigned to the second suspension device. The assignment of an adjustment to a suspension device allows a particularly simple adjustment and the additional assignment of a second adjustment to the second suspension device causes further improved adjustment for mutual coordination of the position of the filling tube to the position of the sorting plate.

The adjustment device preferably has an adjustment eccentric. This allows a particularly simple adjustment during assembly of the feeder when the suspension devices are adjusted to the base unit once during construction via an eccentric adjustment.

It has proven to be advantageous if the first suspension device is mounted via a first pin, which rests in a first guide groove in the adjustment, which is associated with the first suspension device, and / or that the second suspension device is mounted via a second pin which in a second guide groove in the adjusting rests, which is associated with the second suspension device. In particular, both the first and the second suspension device can each be mounted on two pins. This causes a secure storage of the suspension devices and thus secure storage of the sorter and the gate valve unit.

The advantages of the invention will become particularly clear when considered in the overall technical environment of the feeder, which will be described in more detail below.

The filling tube and the Füllröhrchenträger are formed joint-free at the joints, so there are no joints in which residues can accumulate and there is no need to completely separate the filling tube and the Füllröhrchenträger or even such a separation would be counterproductive. Since there are applications in which up to 180 filling tubes are associated with a filling tube carrier, a considerable workload is achieved, which leads to a time and cost advantage when the feed of the filling station of a thermoforming machine must be changed. It is particularly advantageous if the filling tube and the Füllröhrchenträger are integrally formed as a monolithic Füllrohrblock. In this embodiment, the joint-free connection over the entire life of the monolithic Füllrohrblockes is guaranteed, without the need for special fits or seals.

The preparation of such a feeder is facilitated if the filling tubes are arranged terminally on the Füllröhrchenträger, which in principle, however, also has the possibility that the Füllröhrchenträger is positioned at a distance from the free end of the filling tube, so there are appropriate options for the user to the Feeding to the needs of the environment, usually to adapt to the filling station of the thermoforming machine.

It should be emphasized that the joint-free connection of the filling tube with the Füllröhrchenträger is essential, which can be achieved in a particularly simple manner by a one-piece design; It is equally possible that the separately manufactured Füllröhrchenträger and Füllröhrchen are permanently connected by a joining technique, so for example, on a provided from a particular material Füllröhrchenträger injection molded from the same or another material made stuffing tubes are formed, so also the possibility exists that the Füllröhrchenträger and the filling tubes are made of different materials.

It is envisaged that the sorting plate, to the exclusion of a possibility of movement in the vertical direction of vibratory movements for micro-waves, predetermined by a translational degree of freedom in the horizontal direction bidding first guide is offset by the drive in a horizontally directed vibration.

By this mode of operation is initially given a complete departure from the previously used from the prior art method, since a possibility of movement in the vertical direction of vibrational movements is excluded for the microwaves and in particular by the elastic storage of the sorting plate must be waived on buffers and can be. It is not intended and not possible to carry out microwaves in the vertical direction. Since a vibration movement of the sorting plates takes place only in a horizontal direction by the first guide, the product carpet located on the sorting plate moves uniformly over the entire width of the sorting plate under the influence of the products own inertia, so that areas with a reduced provision of products do not surrender

It should be noted that the horizontal vibration movements for the distribution of the products on the sorting plate, a slower relative vertical movement (hereinafter referred to as Sortierhubbewegung) may be superimposed between sorter and filling tube to sort the products in the filling tube. The accelerations of the sorting strokes are by design so low that they do not cause microwaves of the products. In the conventional method of three-dimensional vibration movements of the sorter and the new method of horizontal vibration movements of the sorter slower Sortierhubbewegungen can be superimposed, in a co-moving with the Sortierhubbewegung coordinate system, the microbes in the new method have no vertical component, but only a horizontal Kompente, whereas, in the conventional method, in the coordinate system co-moving with the sorting stroke, the microwells also have a vertical component.

It is also possible that the vibration is excited parallel or perpendicular to the film travel direction, since the advantages associated with the method according to the invention are realized not only in a single predetermined direction, since it is ensured that a uniform adjustment of the products over the entire width of the sorting plate takes place, so their entire surface is covered.

It is particularly favorable if the sorting plate is turned into a horizontal position by means of a second drive utilizing a second guide which has a translational degree of freedom in a guide not parallel to the first direction and which is constructed with the first guide according to the principle of a cross table Oscillation is added, since there is an improved way to dissolve accumulations of product carpet on the sorting plate and move the products on the sorting plate.

According to an alternative, there is the possibility that the sorting plate is excited on the first guide and / or the second guide with a symmetrical vibration, this symmetrical vibration essentially serves to dissolve accumulations and to achieve a uniform distribution of the products on the sorting plate. Alternatively, there is also the possibility that the sorting plate is excited on the first guide and / or the second guide with an asymmetrical oscillation, this asymmetrical oscillation leading to the product carpet moving on the sorting plate, so that with a suitable selection of the excitation it is possible is to move the product carpet in one direction or the other, or even reverse the direction of migration by inverting the asymmetric vibration.

Furthermore, there is the possibility that the amplitude and / or the frequency and / or the symmetry of the oscillation are varied so as to produce a kind of stirring effect, wherein a variation is particularly preferred in which the maximum amplitude of the oscillation is smaller than the gap between the filling tube and the associated breakthrough in the Sorting plate is, in which the Füllrohrende protrudes, wherein the sorting plate can be excited after a defined number of excursions with an amplitude which is greater than the maximum gap between Füllröhrchen and sorting plate so as to solve possibly blocked in the filling tube products. Of course, other variations are also conceivable.

According to a further aspect, the method comprises opposite oscillatory movements of a balance weight to the horizontal oscillatory movements of the sorting plate. Due to the opposite movement of the sorting plate and balance weight, the forces of this vibration system cancel outwards, so that no forces on the other components of the feeder such. B. the basic unit to be transmitted. Due to the reduction or avoidance of vibrations in the base unit, on the one hand, the service life of the electrical and mechanical components increases and, in particular, critical electrical components can be installed in the basic unit without additional effort. This mode of operation is made possible by arranging the sorting plate in a first guide without a gravity-directed movement possibility of micro-vibration vibration movements, which offers a degree of freedom for a horizontal translational adjustment. This feeder is characterized by its simple structure, in which with simple constructive measures, namely essentially the rigidly arranged in the vertical direction first guide the sorter, which can be imposed in the horizontal direction required movement, with depending on the choice of stimulation a loosening the product carpet or its migration on the sorting plate can be achieved.

In order to be able to effect the migration of the product carpet not only in a selected direction, a second guide is provided aligned parallel to the film running direction, which is perpendicular to the first Guided tour and is built with this in the manner of a cross table. By means of this structure of the feed, it is possible to treat the product carpet located on the sorting plate very variably and to move in one or the other direction, this movement being reproducible by the improved storage without the use of elastic buffers. It has proven to be advantageous if the first guide and / or the second guide is designed by guide rails and carriages or slide bearings or as a shaft with guide bushings in the form of ball bushings, as these alternatives can be implemented easily and inexpensively.

It is also favorable if the drive is formed by a first vibrator associated with the sorting plate, by means of which the vibrations for horizontal translational adjustment of the sorting plate on the first guide can be generated. Then it makes sense that for adjusting the sorting plates on the second guide, a second vibrator is provided, wherein the first vibrator and / or the second vibrator are formed by a drive, in particular a servomotor. Additionally or alternatively, there is also the possibility that the first vibrator and / or the second vibrator an eccentric is assigned to produce the desired vibration.

It has proven to be advantageous if a vertical guide for a Sortierhubbewegung in terms of sorting plate and filling tube is attached to the base unit to let sort through the slower relative movement between the sorting plate and filling tube products in the stuffing tubes.

In one aspect, the feeder has a double eccentric located on the first drive so that a first one of the two Cam roller moves the sorting plate and a balancing weight counterweight to the sorting plate is moved in opposite directions over a second cam roller. As a result, the vibrations of the sorter are not transferred to the other components of the feeder, as they are compensated by the balance weight by canceling the forces of the vibration system by the opposite movement of the sorter and balance weight. This allows longer life of the electrical and mechanical components of the feeder, because no vibrations are transmitted to these components. In addition, critical electrical and mechanical components can be installed without additional effort in the basic unit, creating a more compact design is possible. Due to the opposite movement of the sorting plate and the balance weight, the system remains at rest from the outside.

Furthermore, driving this vibration system with a servomotor enables product-specific vibratory motions to be introduced into the sorter plate. In particular, in difficult formats, the vibration curve, which is stored in the servo motor, can be almost infinitely modified, so that no mechanical intervention is necessary. An additional benefit is greater flexibility in entering different formats and quickly solving sorting problems due to the flexibility of the vibrations.

The basic unit and the Absperrschiebereinheit with magnets on magnetic receptacles and couplings for the magnets are designed such that the gate valve unit with the base unit on the magnets and the couplings is releasably connected, so that a motion transmission from the base unit on the gate valve with its gate valve plate on the Magnets and the couplings for the magnets is feasible. Due to the smaller number of components is thus a faster assembly and disassembly of the feeder possible. Another advantage is that the feeder allows easy insertion from the front, whereas in the conventional feeder threading from the top is required, which causes a larger footprint in the conventional apparatus. An additional advantage is that it avoids small mechanical components that can easily be lost during disassembly and assembly for maintenance and / or cleaning purposes. Further advantages are that lighter components can be used and that due to the simpler design of the gate valve unit and frame can be mounted separately on the base unit.

In a first embodiment, the magnets are arranged on the base unit and the couplings on the shut-off slide unit. This has the advantage that the shut-off slide units are cheaper to manufacture, which can be replaced in a basic unit to meet the different requirements for different types of tablets or the like. However, an inverted arrangement is also conceivable or a combination of the alternative arrangements.

It has proved to be advantageous if the shut-off slide unit has two shut-off slide plates arranged one above the other, wherein the magnets and the clutches are arranged offset in such a way that the shut-off slide plates are movable in opposite directions.

Preferably, the feeder comprises a format unit and the base unit has a suspension device, wherein the format unit comprises the sorting plate, the shut-off slide unit with filling tubes and filling shoes, and wherein the suspension device and the format unit are configured such that the format unit can be separated from the base unit without tools. Thereby A faster assembly and a faster format change are possible. Another advantage is that the number of mechanical components is reduced and that no small parts are necessary, which can easily be lost during the format change.

It has proven to be advantageous if the format unit has an adapted recess and the format unit can be clamped on the suspension device via a pneumatic cylinder. In this way, the format unit is secured against accidental slipping and basic unit is designed to be more cleaning friendly, since the front of the feeder receives a smooth surface.

According to a further aspect, it is provided that the basic unit for a releasable connection of the base unit with a gate valve unit and for a movement transmission from the base unit to the gate valve unit by means of magnetic coupling via magnets on magnetic recordings and couplings is designed.

The receptacles for the Absperrfinger are formed continuously through the base plate and the base plate is disposed between a lower plate with second through holes and an upper plate with at third through holes such that the Absperrfinger are secured in the receptacles of the base plate, both the second through holes also the third passage openings are associated with the first passage openings.

Thus, the recordings for the Absperrfinger can be made faster and cheaper, since the recordings do not need to be produced consuming with a milling device, but can be made for example with a laser cutting machine. Also, in Depending on the materials used also punching, casting, spraying or rapid prototyping method used. Furthermore, due to the arrangement of the lower retaining plate and the upper retaining plate, the locking fingers are secured in the receptacles, although the receptacles are formed continuously by the base plate. Another advantage is that the formation of the receptacles for the Absperrfinger can be performed simultaneously with the formation of the first through holes in the base plate.

In the case of the shut-off slide unit, a plurality of shut-off fingers is preferably assigned to the first through openings in the base plate. As a result, both a faster production and a simpler structure is achieved, which is particularly advantageous for cleaning operations.

Furthermore, in the case of the shut-off slide unit, the receptacles for the shut-off fingers may each have a constriction at the interface to the first through-openings. In this way, the safety of the Absperrfinger is improved during operation of Absperrschiebereinheit.

In the case of the shut-off slide unit, the first through openings are advantageously arranged congruently with the respective second through openings and the corresponding third through openings. About filling cone in the sorting plate and inlets of the filling tube faster delivery and sorting can be effected.

Furthermore, the Absperrfinger can be formed of a solid material, in particular steel, aluminum or plastics, which in particular the durability and the load capacity of the feed and Sorting device can be improved. Furthermore, the Absperrfinger may have a soft coating, in particular a silicone coating. This leads to the fact that sensitive materials are sorted more gently, and on the other hand, this causes a reduction in impurities. This is an important consideration especially for medicines or food.

According to a further embodiment of the gate valve unit these advantages are achieved in that the Absperrfinger are formed of a soft material, in particular silicone.

In a gate valve unit, an upper retainer plate is disposed on the base plate and at least one attachment means for attaching the upper retainer plate to the base plate is mounted. This has the advantage that the time required for disassembly significantly reduced and cleaning is simplified.

It has proven to be advantageous if the fastening means comprises a lock, wherein in the upper holding plate the lock actuator is assigned a release and Feststellaussparung that by a displacement of the base plate to the upper plate in the release and locking recess, the upper plate of the base plate is released or detected on the base plate. As a result, a fast and secure attachment or release of the upper plate is effected. Preferably, the attachment via a clamping device such. B. causes a Kunststoffklipser. In this way, the upper retaining plate is secured against slipping during operation.

In another Absperrschiebereinheit lie instead of the base plate, a corresponding lower base plate with lower through holes and a corresponding upper base plate with upper through holes, wherein the lower base plate and the upper base plate are arranged to each other such that in each case the lower passage opening and the corresponding upper passage opening are associated with a corresponding number of filling tubes.

Preferably, the gate valve unit comprises at least one guide member having a lower guide for guiding the lower base plate and an upper guide for guiding the upper base plate, wherein the at least one guide member and the lower base plate and the upper base plate between a lower cover plate and an upper cover plate are arranged , This allows the base plates in the gate valve unit to be moved precisely. Furthermore, the guide parts for accelerated assembly and disassembly and to simplify the cleaning in the upper cover plate and the lower cover plate plugged and thus easily determined. The lower and / or the upper cover plate may have a cover plate.

It has proven to be advantageous if the lower base plate for the lower guide and the upper base plate for the upper guide have different corresponding codings. Due to the differences in the coding of the guides and the corresponding differences in the coding of the upper and lower base plate, a permutation of the base plates can be prevented.

It is very particularly preferred if the lower base plate has a first height and the upper base plate has a second height, the first height being different from the second height, and the lower guide being a lower guide groove having a width matching the first height and the upper guide as an upper guide groove with a matching to the second height width are formed. Due to the asymmetry of the dimensions, a permutation of the lower and the upper base plate during installation is prevented in a simple mechanical manner.

In a gate valve unit, the guide part on the upper cover plate side facing a first lock and on the lower cover plate side facing a second lock in such a way that the first lock and the second lock are different, wherein on the upper cover plate on the guide part facing side, a first key to the first lock for connection to the guide member is formed and formed on the lower cover plate on the guide part facing side, a second key to the second lock for connection to the guide member. With an asymmetrical design of the guide part, a permutation during installation can be prevented automatically.

In an advantageous embodiment, the first lock is formed as an upper guide projection on the top of the guide member, the second lock is formed as a lower guide projection on the underside of the guide member, the first key on the underside of the upper cover plate as one to the upper guide projection formed matching upper guide recess and the second key is formed on the upper side of the lower cover plate as a matching with the lower guide projection lower guide recess. Additionally and / or alternatively, instead of a mechanical coding other codings, such. As a magnetic coding possible to distinguish the top and bottom of the guide member and adapt to the different counterparts on the lower and the upper cover plate accordingly.

In a gate valve unit, the upper base plate is arranged movable relative to the lower base plate, wherein an end position of the upper base plate is designed to be adjustable. As a result, tolerances in production, construction and operation can be better compensated.

Preferably, the gate valve unit comprises a pneumatic cylinder for moving the upper base plate and a stop for limiting the movement of the upper base plate, wherein the stopper is designed to be adjustable by a motor.

Conveniently, two of these Absperrschiebereinheiten are connected to each other such that their passage openings are congruent to each other, wherein the Absperrschiebereinheiten the Absperrfinger are arranged differently, so that the respective through holes associated Absperrfinger the Absperrschiebereinheiten are each offset from each other.

Alternatively, the Absperrfinger necessary for the Absperrschiebereinheit are integrally formed with the base plate.

Thus, the Absperrfinger can be made faster and cheaper with the base plate, since on the one hand no recordings for the Absperrfinger need to be made consuming with a milling device and on the other hand no Absperrfinger made in additional process steps and must be introduced. An additional advantage is that in the base plate the Absperrfinger can be formed during the formation of the through holes. Furthermore, the Absperrfinger hang piecewise or completely together, whereby the production of Absperrschiebereinheit is simplified. One Another advantage is that the conventional recordings for the fingers can be saved, whereby a cleaning of Absperrschiebereinheiten can be performed better and faster.

Preferably, in the gate valve plate, the passage openings in the base plate are associated with a plurality of Absperrfingern. As a result, both a faster production and a simpler structure is achieved, which is particularly advantageous for cleaning operations.

In a gate valve plate, an upper retainer plate is disposed on the base plate, and at least one attachment means for attaching the upper retainer plate to the base plate is mounted. This has the advantage that with a top plate a desired spacing of the base plate can be easily achieved.

In the alternative integral configuration of the base plate with the Absperrfingern can be provided according to the first embodiment of the base plate fasteners with fasteners, a corresponding arrangement of two base plates, guide parts, codings, different heights and so on, so that to avoid repetition of the description part of the first Design of the base plate is referenced.

In an integrated control cabinet for a feeder, it is arranged in a base unit of the feeder in a dust-tight sealed area. As a result, a space-saving design without compromising the reliability of the electrical components is achieved. Furthermore, this allows a faster cleaning of the filling line.

Preferably, the integrated control cabinet forms a wall, in particular a rear wall of the basic unit. This leads to the advantage of a further reduced space requirement and a particularly stable construction.

It has proved to be favorable when the integrated control cabinet is pivotally arranged in the base unit, so that the integrated control cabinet serves as a door of the base unit for releasing and closing a second access for mechanical maintenance in the base unit. As a result, mechanical maintenance work in the base unit can be performed more easily.

In an advantageous embodiment, the integrated control cabinet on a cabinet door with a first locking device and a second locking device for the door of the base unit, wherein the first and the second locking device are designed for different keys.

Particularly preferably, the door is formed as a rear door of the basic unit in the integrated control cabinet, whereby the operability is increased.

It has proven to be advantageous if a coolant circuit in the integrated control cabinet and a coolant connection, in particular in the cabinet door are arranged on the outside of the cabinet. In this way, the waste heat can be better dissipated and the reliability and the life of the electrical control can be increased. Due to the dust-tight completion of the integrated control cabinet relative to the base unit, which is loaded by pore dust, the electrical control can be additionally cooled by fans in the recirculation process to transport the waste heat to the coolant circuit.

Furthermore, in the basic unit a slide for synchronization and a drive, in particular an electric drive for the supply are arranged such that the drive for the supply is stationary. In addition, the drives for the storage and the Sortierhub be stationary. This has the advantage that the electrical lines are not cyclically loaded and thereby extends the service life. An additional advantage is that the motors do not need to be moved so that lower power consumption can be achieved during operation. In addition, the mechanical components can be made smaller due to the weight savings of the components to be moved.

In this technical environment, the advantages of the invention emerge particularly clearly, since each feature complex, even isolated considered, seeks and effects an improvement in the delivery.

In the FIGS. 1 to 6 1, a feeder 1 is shown in an overview, while the individual components of the feeder 1 are described in their interaction in the following figures.

The in the FIGS. 1 to 6 shown feed 1 serves to control bulk stored products in the wells of a continuously or cyclically moved film web to convict. This feeder 1 comprises a product receiving the bulk material as a reservoir 18 from which the products are transferred to a sorting plate 3, which sorts the products so that they take the pattern of the wells formed in the film web, wherein the sorting plate 3 in its bottom openings 13, into which protrude the upper ends of Füllröhrchen 10, in which the products are sorted. The Füllröllchen 10 are each associated with two Absperrfinger that serve to selectively release the lowest product from the filling tube 10 and into the channels 23 of a filling shoe 24 (FIGS. Fig. 6 ) to deliver the filling shoe unit 25 in the gate valve unit 4. The Absperrfinger are formed in an upper gate valve plate 19 of the gate valve unit 4 and a lower gate valve plate 20 of the gate valve unit 4 ( Fig. 5 ), which carry the Absperrfinger for all Füllröhrchen 10. The sorting plate 3 itself is mounted on a first guide 27, which permits movement in a horizontal translational direction, this movement being produced by means of a first drive 21, which can set the sorting plate 3 in vibration ( Fig. 12 ).

According to an embodiment not shown in the drawing, it is further possible to provide a second guide, which is constructed with the first guide in the manner of a cross table, so as a second possibility of movement in a horizontal direction which is not parallel to the first horizontal direction to enable.

With such a constructed feed 1, it is possible to give up the products from the bulk material from the reservoir 18 via the product promotion 22 on the sorting plate 3, of which the products are distributed and moved by the sorting plate 3 by means of vibrators having drives 21 in a vibration is added, whereby a loosening of the product carpet takes place with a symmetrical oscillation, while an asymmetric oscillation causes the product carpet to move in one direction as a result of the inertia of the individual products. Due to the predetermined guidance of the sorting plate 3, it is possible to reproduce and reverse the movement of the product carpet, so that a uniform product distribution over all upper ends of the filling tube 10 can be achieved by the appropriate excitation of vibrations of the sorting plate 3.

The Fig. 7 shows a perspective view of a base unit 2 and a sorting plate 3 and a gate valve unit 4 with Füllröhrchen 10 comprising format unit 12 in a disassembled state. At a feeder, products from one in the Fig. 7 Not shown hopper led to the sorting plate 3. There they become horizontal Distributed vibrations and sorted by up and down movements in the filling tube 10. In the filling tube 10, the tablets are aligned and then separated via the gate valve unit 4. A first suspension device 5 for the sorting plate 3 and a second suspension device 6 for the gate valve unit 4 are arranged on the base unit 2, wherein the sorting plate 3 is not rigidly or elastically connected to the gate valve unit 4, thus a relative adjustment of the gate valve unit 4 to the sorting plate 3 is possible.

The Fig. 8 shows a plan view of the arrangement of the filling tube 10 with respect to the sorting plate 3 with the openings 13, wherein the filling tubes 10 are arranged centrally in the openings provided for them 13 with the optimum distance 11 of the filling tube 10 to the sorting plate 3, whereby the sorting of the Tablets can be optimized.

The Fig. 9 shows an adjusting device 7 for relative adjustment of the sorting plate 3 to the gate valve unit 4. The adjusting device 7 is mounted on the inside of a wall 14 of the base unit 2, wherein in this embodiment, the first suspension device 5 is arranged in an overlapping region on the outside of the wall 14 , The entire first suspension device 5 for the sorting plate 3 can be moved thereby, so that the suspension of the sorting plate 3 can be made congruent with the suspension of the gate valve unit 4 via an Exzenterverstellung with a Verstellexzenter 8. The first suspension device 5 is mounted on first pins, which rest in first guide grooves 9 in the adjusting device 7. Although it is in the Fig. 9 is not shown, there is also the possibility that a corresponding adjustment is provided for the second suspension device 6.

In the Fig. 10 schematically shows a part of the feeder, which serves for the ordered simultaneous filling of small parts in the arranged on a surface transversely and parallel to the strip running direction cups of the tape, including a plurality of filling tubes 10 are provided, which are summarized by a Füllröhrchenträger 15. The connection points 16a of the filling tube 10 and the Füllröhrchenträgers 15 are formed without joints, namely with the embodiment shown in the drawing by integral formation of the filling tube 10 and the Füllröhrchenträgers 15 as a monolithic Füllröhrchenblock 16. It is in the Figures 10 and 11 have shown that the filling tubes 10 are arranged terminally on the filling tube carrier 15. In the FIGS. 4 and 5 It is shown that in each of the filling tubes 10 a total of two openings as a lower opening 17a and an upper opening 17b are formed, which make it possible to adjust Absperrfinger into the tube interior, so as to be able to selectively carry out a separation and storage of small parts.

Like in the Fig. 12 As shown, a vertical guide 26 may be arranged on a base unit 2 for sorting strokes with respect to the sorter plate 3 and the filling tubes 10. Due to the slower sorting strokes in the vertical direction, the products are sorted into the filling tubes 10, while they are distributed on the sorting plate 3 by the vibration movements in the horizontal direction.

In this case, it is also possible to vary the amplitude and / or the frequency and / or the symmetry of the oscillations, so that great flexibility is provided and that the sorting behavior influenced by the size of the products, their support surface and their masses can be taken into account accordingly.

In the Fig. 13 For a preferred embodiment, the drive of the sorting plate 3 is shown schematically. The servo motor 21 with a double eccentric 29 transmits to a first cam roller 30 and a second cam roller 31, the vibration movements, wherein the first cam roller 30 with the sorting plate 3 and the second cam roller 31 are connected to a balance weight 32. About a spring assembly, the sorting plate 3 and the balance weight 32 on the double eccentric 29, biased so that upon rotation of the double eccentric 29, the movements of the sorting plate 3 and the balance weight 32 are correspondingly in opposite directions. The opposition of the movements is in the Fig. 13 represented by the arrows in opposite directions. By the opposite movement of this vibration system, the forces cancel, so that a power transmission from the vibration system to the other components of the feeder 1 is prevented.

The Fig. 14 shows a schematic representation of the feed with a base unit 2 and a gate valve unit 4 in the disassembled state. The basic unit 2 is stationary and the gate valve unit 4 can be selected and changed product-specifically according to the requirements of the products to be supplied and sorted.

The Fig. 15 shows a second schematic representation of the feed to the base unit 2 and a format unit 12, which includes the sorter 3, the gate valve unit 4, the filling tube 10 and the filling shoe unit 25 with the Füllschuhen 24, wherein the format unit 12, the requirements of the supplied and sorted Small parts can be selected according to the product and changed. Furthermore, the base unit 2, the suspension devices 5 and 6, so that the format unit 12 is tool-free from the base unit 2 separable. The small parts to be supplied to the hopper on the Vibrating unit passed into the sorting plate 3. There they are sorted by up and down movements in the filling tube 10. In the filling tube 10, the tablets are aligned and then separated via the gate valve unit 4. About the filling shoes 24, the tablets are placed in the mold sheet under the feed.

In the Fig. 16 In one embodiment of the present invention, it is shown that the gate valve unit 4 has slide guides 33 and, for example, two gate valves 19 and 20 arranged one above the other. The Fig. 17 shows in an enlarged view for the embodiment of Fig. 16 in that a magnet 34, namely a permanent magnet, is mounted on a magnetic receptacle 35 on the base unit 2 and the coupling 36 for the magnet 34 is mounted on the lower gate valve plate 20 of the gate valve unit 4.

In order to be able to separate the tablets, in an advantageous embodiment, the gate valves 19 and 20 are moved back and forth in opposite directions, these movements being transmitted directly from the base unit 2 to the gate valves 19 and 20. The gate valves 19 and 20 are guided in the slide guides 33 and thus perform a linear movement.

When switching the feed to a new format of the tablets, the gate valve unit 4 has to be decoupled from the basic unit 2 or coupled to it. Like in the Fig. 17 is shown, the magnetic coupling and thus the connection between the base unit 2 and the gate valve unit 4 via the magnet 34 on the magnet holder 35 and the coupling 36 is effected. Due to the fixed magnetic coupling, the movements for the gate valves can thus be transmitted via the magnet.

In the Fig. 18 it is shown that the format unit 12 can be secured in operation against unwanted movements relative to the base unit 2 by the format unit 12 is stretched onto the suspension device 5 on the base unit 2 with a pneumatic cylinder 37. Like in the Fig. 19 is shown, a recess 38 is provided, in which the pneumatic cylinder 37 can engage.

Fig. 20 shows a first embodiment of the base plate 42 for the gate valve unit 4 of the feeding and sorting device 1 according to the present invention. The base plate 42 has first through holes 49 and receptacles 43 for first Absperrfinger 41. The receptacles 43 for the Absperrfinger 41 are formed continuously through the base plate 42.

The receptacles 43 for the Absperrfinger 41 can be cut out of the base plate 42, for example by means of a laser cutting machine together with the first through holes 49. It is advantageous if the receptacles 43 for the blocking fingers 41 have a narrowing at the interface with the first through-openings 49. Preferably, as in the Fig. 20 represented, in each case a number of receptacles 43 for the Absperrfinger 41 associated with the first passage openings 49.

Fig. 21 shows the first embodiment of the gate valve unit 4 according to the present invention in an exploded view and Fig. 22 shows the first embodiment of the gate valve unit 4 in the assembled state. The base plate 42 is arranged between a lower holding plate 44 with second through-openings 49a and an upper holding plate 45 with third through-openings 49b such that the blocking fingers 41 are secured in the receptacles 43 of the base plate 42 are, wherein both the second passage openings 49a and the third passage openings 49b associated with the first passage openings 49.

The Fig. 23 shows the base plate 42 with the Absperrfingern 41 according to an embodiment of the present invention with an upper plate 45 and a lower plate 44 in the locked state.

On the base plate 42, the upper holding plate 45 is preferably mounted with corresponding through holes in the locked state so that these through holes are substantially congruent with the through holes 49 of the base plate 42.

An enlarged view of the fastening device in the locked state is in the Fig. 24 as well as in the released state in the Fig. 25 shown. In the locked state is a lock 47, which is arranged on the base plate 42 and having a neck portion and a head portion, in a narrowed portion of the release and locking recess 46 in the upper plate 45, so that the head portion of the fastener 47, the upper Retaining plate 45 on the base plate 42 secures. In the released state, however, the lock 47 is in a widened region of the release and locking recess 46 in the upper support plate 45, so that the upper support plate 45 can be removed from the base plate 42 via the head part. The Indian Fig. 25 Arrow shown indicates the direction in which the upper support plate 45 can be moved to backup on the base plate 42. The upper holding plate 45 from the Fig. 25 is moved parallel to the base plate 42 in the arrow direction for securing or moved in the opposite direction parallel to the release. In this way, the upper holding plate 45 without tools from the base plate 42nd be separated and removed. Similarly, the lower retaining plate 44 can be secured.

The Fig. 26 shows the gate valve unit 4 according to a further embodiment. The gate valve unit 4 according to this embodiment has, instead of the base plate 42, a corresponding lower base plate 42a with lower passage openings and a corresponding upper base plate 42b with upper passage openings. The lower base plate 42 a and the upper base plate 42 b are arranged in the operating state to each other such that in each case a lower passage opening and a corresponding upper passage opening of a corresponding number of filling tubes 10 are assigned. By storing in guide members 53, the base plates in the gate valve unit 4 can be moved precisely.

The Fig. 27 shows an enlarged view of the guide member 53 in the gate valve unit 4 according to another embodiment. In the Fig. 27 It can be seen that the guide parts 53 may have different codes both for connection to an upper cover plate 52 and connection to a lower cover plate 51 and for guiding the lower base plate 51 and the upper base plate 52. The lower base plate 5a has a first height H1 and the upper base plate 5b has a second height H2, wherein the first height H1 differs from the second height H2. The upper recess 55 on the upper cover plate 52 and the lower recess 54 on the lower cover plate 51 are configured differently. It can, for. B. the lower recess 54 extend over the entire height of the lower cover plate 51, while the upper recess 55 extends only over a partial height of the upper cover plate 52. In addition to the height and the width and the length of the recesses may be configured differently. For a suitable one Connection are on the top of the guide member 53 adapted to the upper recess 55 upper guide projection 57 and formed on the underside of the guide member 53 adapted to the lower recess 54 under guide projection 56. The asymmetry of the lower guide projection 56 and the upper guide projection 57 ensures proper installation of the guide members 53.

The Fig. 28 shows that the lower guide is formed as a lower guide groove 58a having a width B1 matching the first height H1, and the upper guide is formed as an upper guide groove 58b having a width B2 matching the second height H2. The asymmetry of the lower and upper guide grooves with the asymmetry of the lower and upper base plates 42a and 42b mechanically prevents interchanging of the base plates during installation.

The Fig. 29 shows the gate valve unit 4 according to another embodiment in cross-sectional view, in which the upper base plate 42b is arranged adjustable.

The end position of the upper base plate 42 b is adjustable in order to ensure optimum shut-off of the tablets in the filling tube 10. Preferably, the adjustment is infinitely adjustable. This can be done via a motor. The upper base plate 42b is moved by a pneumatic cylinder 59 having a continuous piston rod. Via a stop 60, the desired position can be adjusted, wherein the stop is adjustable via the motor, so that no intervention by hand are necessary.

The technical features of these embodiments of the present invention may be combined. Furthermore, it is possible; replace the base plate 42 with a number of sub-base plates, or replace the upper base plate 42b with a number of upper sub-base plates and the lower base plate 42a with a number of lower sub-base plates.

The Fig. 30 shows the base plate 42 for the Absperrschiebereinheit 4, which has a Füllröhrchen 10 corresponding number of Absperrfinghrchen 41, each associated with the respective filling tube 10, and through holes 49, wherein the Absperrfinger 41 are integrally formed with the base plate 42.

Fig. 32 shows the base unit 2 with the integrated control cabinet 62 in which a second access 65 for mechanical maintenance in the base unit 2 is opened. The integrated control cabinet 62 is pivotally mounted in the base unit 2 such that the integrated control cabinet 62 serves as a rear door 61 of the base unit 2 for releasing and closing a second access 65 for mechanical maintenance. For possible maintenance work on the mechanical components of the integrated control cabinet 62 can be pivoted together with the electrical components to open the second access 65, said second access 65 can be opened without touching the electrical components. Thus, it is possible to perform mechanical maintenance by a mechanic without the assistance of an electrician.

In the Fig. 33 For example, the integrated cabinet 62 is shown in an open condition where a pivoted cabinet door 63 releases a first access 64 for electrical maintenance. This cabinet door 63 corresponds to a conventional cabinet door that can be opened only with a special key to perform electrical maintenance. Accordingly, a first closing device for the switching cabinet 62 and a second closing device for the door 61 of the basic unit 2 are designed for different keys.

In the Fig. 31 It is shown that the integrated control cabinet 62 may have a coolant connection 66 on the cabinet door 63 for a coolant circuit. The coolant circuit is z. B. formed as a coolant plate in the cabinet door 63 to dissipate the waste heat from the integrated cabinet 62 in a simple manner.

In the Fig. 34 is a schematic representation of an arrangement of electric drives 68 and a carriage 69 for synchronization in the base unit 2 with the integrated control cabinet 62 shown. In the basic unit 2, the slide 69 for the synchronization and the electrical drives 68 for the supply are arranged such that the electric drives 68 are stationary. The outer housing of the base unit 2 with the housing walls 67 is stationary and the electric actuators 68 are arranged so that they perform only format adjustments with, the full movements such. As synchronization, sorting and lowering of the drives 68 are not carried out with.
