Description

20 25 30 35 .. .....-..-...............- .; ¿l 454 632 2 use of extremely high pressures, and it is impossible to fill long pipe plates (eg with 2 m length).

In addition, the high pressures used also favor the undesired squeezing of water from the suspension, so that changes in quality occur along the length of the pipe.

In the case of the known filling device, the foot frame strip must be pushed onto the pipe plate by hand after the injection process has been carried out. This is a very difficult to implement and correspondingly labor-intensive process, as the foot frame strip must receive the lead core for each individual pipe section in a suitable manner in the central area and also insert itself into the pipe sections with its corresponding approaches. In this system, the lead core projecting necessarily from each individual pipe section prevents automation of the process.

As a result, the subsequent washing, weighing and buffering must also be carried out separately, which is a total disadvantage of crusts. For prevention The open machine system must be flushed and service work performed, which is labor intensive, leads to loss of active pulp and causes waiting times.

The object of the invention is, in view of the state of the art described, to propose, while avoiding the described disadvantages, a fully automatically operating pipe plate filling machine by means of which even very long pipe plates are so fillable with pasty active mass and so ready-made that the pipe plates have one. reproducible quality uniformity. The object is achieved according to the invention in that in a magazine for unfilled pipe plates stacked therein a feeding device is arranged, by means of which a pipe plate is displaceable at a time on a pivot table arranged thereon, on which the fixed pipe plate is pivotable from its horizontal position to a vertical position located below the nozzles, that the nozzles are arranged to be raised and lowered, that in the direction of transport behind the turntable are arranged in turn first a device 10 for pressing foot frame strips, then a welding station for welding together of the baseboards with the casings of the pipe plates, then a draining station, a weighing and control station and finally a plate buffer.

The essence of the invention lies in starting from a storage magazine, in which unfilled pipe plates are stacked on top of each other, during the passage of six consecutive stations, filling each pipe plate with active mass, closing the pipe plates with a foot fitting strip, welding the foot fitting strip with the housings, providing an opportunity to drain the wet plate and then weigh it and insert into it a plate buffer. In each cycle, six plates are fed simultaneously to the successive stations in the tube plate filling machine.

After the end of the transport function, the measures described above take place simultaneously in the individual stations. Thanks to the fully automatic workflow, high productivity is achieved. By filling the individual pipe plates in a vertical state, a blow-free injection of pasty active mass is possible even on very long plates and the risk of incorrect dosing is reduced. The weight of each individual plate is checked fully automatically and the possibility is provided that the machine is automatically switched off in the event of incorrect dosing. Thanks to the fully automatic work process, the pipe plate filling machine according to the invention can be encapsulated, so that it can be constructed in an environmentally friendly manner in combination with a closed paste line.

Suitably there is a machine frame with three planes arranged one above the other at a mutual distance, the middle of which is the working plane, on which the individual construction stations are arranged, the auxiliary units being distributed on the other two planes. In this way, an extremely compact machine can be achieved and the transport between the individual stations is structurally simplified.

The tube plate magazine has facing the turntable an outlet slot arranged in the working plane, on both sides of which are arranged vertical guide strips in the form of wedge-shaped, axially movable square bars, which serve for a safe centering and control of the plate movement on the turntable. The plate ejection from the magazine takes place by means of a pneumatically operated, reciprocating sheath device.

The swivel table preferably consists of two superficially arranged table plates which are pivotally mounted in the machine frame and can be brought by means of a pneumatic cylinder from the horizontal position to a vertical position below the nozzles. The insides of the table tops are suitably coated with a silicone rubber mat profiled corresponding to the tube top, which serves to hold the boards securely and also to prevent water from escaping from the jacket pipes while carrying pasta particles. The avoidance of material loss and of liquid leakage further facilitates the achievement of the objective of filling longer pipes with pasty active mass without the addition of flow aids.

The movement of the table plates towards each other is advantageously effected by means of correspondingly mounted parallelogram levers, which are connected to a pneumatic cylinder. In addition, the upper table top can be provided with screw bolt rows on both sides for additional holding of the pipe plates, especially against displacements in the vertical condition. This is important therefore, because by attaching the submersible nozzles a vertical force is exerted on the retained pipe plates. The same force applies when the nozzles are pulled up at the end of the injection process.

The nozzles themselves are arranged for uniform movement on a nozzle strip, which is connected to the piston pump via flexible hoses. The stroke and activation time of the cylinder belonging to the piston pump are adjustable, so that the most different plate sizes can be filled in a simple way. During the suction stroke of the piston pump, a rotary screen is active 10 15 '20 25 30 35 454 632 i. _ 5. for avoiding clogging, which strainer is arranged in the inlet to the pasta mixer. The movement of the nozzle is effected by means of a connected compressed air cylinder.

An equally advantageous novelty of the tube plate machine according to the invention lies in the arrangement, above the working plane in the machine frame, of a magazine for foot frame strips in a height-adjustable manner, with which magazine in the lower position is operatively connected to a pressing device. This pressing device suitably consists of a plate pivotally arranged behind the magazine and a compressed air cylinder connected to the automatic control, arranged below the working plane, which acts on the plate. The plate is equipped with a series of ejection pins, so that the lower foot frame strip in the magazine is fully automatic and can be easily pressed onto the tube plate filled with paste. In the next workstation, the foot frame strips are then welded together with the casings of the pipe plates, preferably by means of an ultrasonic welding device, which is arranged to be raised and lowered in the machine frame and for this purpose is connected to a compressed air cylinder.

When the necessary draining of the pipe plates filled in this way is successfully carried out in a vertical position, in a favorable embodiment of the pipe plate filling machine according to the invention a corresponding turning device is arranged. This consists of a pivotally arranged table plate, which holds the plate applied in a horizontal condition and after activation by means of a pneumatic cylinder guides it to a vertical position, in which the plate with its plate flaps is held in the machine frame. Preferably, there is an elongate hole in the table top, through which a plate displacement device reciprocating parallel to the working plane grips, which for this movement is associated with its own pneumatic cylinder. The plate displacement device displaces the plate brought to the vertical position from the pivot area. 454 UI 10 15 20 25 30 35 632 6 The transport to the weighing and control station takes place with the end of a gripping rail. There, the plate flaps are arranged on moldings, which are connected to a road by means of rods. This checks whether the is-weight is within set tolerances and causes the next automatic start.

The transport system ensures simultaneous transport of the pipe plates present in the individual stations to the next processing station, so that a continuous process in an automatic cycle is feasible. The transport system mainly consists of two separate, parallel to each other and lifting and lowering gripping rails arranged in the working plane of the machine frame, in the recesses of which the plate flaps engage for transport. The gripping rails are moved axially back and forth by means of a connected pneumatic cylinder.

The lifting and lowering ability is advantageously achieved by means of rotatably arranged rotatable round bars, which have pins, by means of which the rotational movement of the bars is transferable to the gripping rails via carrier blocks, so that a lifting movement occurs there. The carrier blocks, to which the gripping rails are attached, can be connected to the central round bars by means of flat iron. Connected to the flat iron are two mutually parallel sliding angles, via height-adjustable screws. The sliding angles participate in the lifting and axial movements of the gripping rails.

The beveled legs of the sliding angles provide the plate transport in the buffer station.

All fuels, such as pneumatic cylinders, are connected to an integrated control unit and their work is cyclically adapted to each other.

Further details, features and advantages of the pipe plate filling machine according to the invention appear from the following description with the accompanying drawing, in whose only figure the machine is shown in its entirety in perspective.

In total, the pipe plate filling machine shown consists of - .. L 10 15 20 25 30 35 454 6: 2 7 seven workstations, which 1 machine frame operates on the middle working plane and according to the device together with the auxiliary units are arranged below or above the central working plane of the machine frame. The first workstation is a storage magazine I, which is filled with about 30 unfilled, superimposed pipe plates. The pipe plates consist of a grid with lead cores and tubular casings of electrolyte-permeable material pushed over them.

The next workstation is the filling station II, where the filling of the annulus between the lead cores of the pipe plates and the casings with pasty active mass is carried out by an injection process. In the following strip pressing station III, the foot frame strips are pressed on and welded together with the pipe plates.

The sealing takes place in the adjoining welding station IV by means of an ultrasonic welding apparatus.

This is joined by a draining station V, a weighing and control station VI and a plate buffer station VII. In each cycle, seven plates are treated simultaneously, which are advanced from station to station. The transport system provided for this purpose is explained at the end of the description.

The machine frame consists of square profiles 56, which are welded together so that there are three support planes for the individual device parts, of which planes the middle plane forms the working plane. This is formed mainly by two square profiles 57, S8 arranged at a distance from each other in parallel.

These support on the right side of the figure a box-shaped plate magazine 21, in which stacked plates (not shown) are stacked on each other. The bottom tube plate is shown for the sake of clarity with a dashed line in the figure. In the direction of the pivot table arranged below it, the plate magazine 21 is provided with a slot 22, through which one tube plate can be projected at a time. The transport is responsible for the pneumatic cylinder 19 arranged below the working plane, to which a magazine tongue 20 arranged in the working plane 454 632 10 15 20 25 30 35 8 is attached, the front end of which is adapted to the grid shape and which projects the lower tube plate from the plate magazine 21 through the slot 22 and into a gap 25 present in the turntable, which is formed by table plates 23 and 24 arranged opposite each other.

Upstream of the gap there are wedge-shaped square rods 26 in the plate magazine 21, which rods center the plate pockets. When passing the suspension tabs 13 projecting over the dimension of the plate pockets, the square bars 26 are lifted and fall again after passing.

The turntable formed by the table tops 23 and 24 is designed so that it pours the inserted tube tops. For this purpose, the table plates 23 and 24 are connected to each other and connected to a pneumatic cylinder 60 by means of a parallelogram lever 59. This moves the table plates 23 and 24 towards each other, which plates are provided on the inside with profiled silicone rubber mats, which tightly enclose them therebetween arranged pipe plates. Thereafter, the turntable is pivoted by means of a pneumatic cylinder 27 to a vertical position, as shown by the arrow. The table is then under a dyslist 28.

The nozzle strip has a number of nozzles corresponding to the number of pockets, which are connected to a piston pump 30 by means of flexible hose lines 31. The nozzle strip 28 can be raised and lowered by means of a pneumatic cylinder (not shown in the drawing) arranged above. After lowering the nozzle strip 28 into the open pipe ends of the plate, the cylinder 29 belonging to the piston pump pumps by means of the piston pump 30 pasty, active mass through the flexible hose lines 31 and into the pipe plate pockets 32. The stroke of the cylinder 29 is by means of a hexagon nut 33 and a spacer tube 34 precisely adjustable and thereby adaptable to different plate sizes. After the expiration of a similarly adjustable time, the cylinder 29 returns. During this suction stroke, a rotary screen 35 runs, which is integrated in the supply line to the pasta mixer. From there, the rotating screen 35 with the desired viscosity is supplied to the rotating screen 35.

In this vertical filling position, an axial force is exerted on the clamped pipe plate by the indentation and extension of the nozzle. For holding and displacing, there are screws 36 in the table top 24, which screws are pushed behind the grid so that the plate cannot slide downwards. The screws 37 also present have tips which are pressed between the pipe cross-sections to prevent the plate from being pulled up by means of the outwardly moving nozzle strip.

After the nozzle has been moved upwards, the pneumatic cylinder 27 pulls the turntable back to the horizontal position, whereupon the tube plate exposed after the opening of the table tops 22 and 24 takes place to the next station. In this, a magazine 38 for stacked foot frame strips is mounted above the working plane in the machine frame in a height-adjustable manner. The construction of the magazine 38 is such that the foot mandrel strips contained therein are precisely guided laterally and arranged slidably under the influence of gravity. The lower strip rests on pin 39. After lowering the magazine 38 by means of a pneumatic cylinder 40, the lower strip in question lies exactly in front of the pocket end of the filled tube plate 41. On the magazine is pivotally suspended a plate 43, which is provided at the bottom with a series of ejection pins 44 and in which in a lowered position a pneumatic cylinder 42, not shown in the drawing, acts. As can be seen, the pins 44 are arranged slightly above the holding pins 39 and they are arranged to grip through the magazine. The pneumatic cylinders 42 and 40 return successively to their initial positions.

The tube plate thus sealed is then guided in the working plane forward, to the processing station IV, in which in the upper area of the machine frame a sink is attached? and raised an ultrasonic welding device 46. The movement is effected by means of a pneumatic cylinder 45, which lowers the ultrasonic welding device 46 for carrying out the welding, until it is in a position for welding the foot frame strip with the flat casings. The pneumatic cylinder then returns to its initial position.

In station V, the pipe plate is drained off. To this end, it is moved by means of a rotating device from its horizontal position to a vertical position. For this purpose, a table 50 is pivotally attached to the machine frame in the working plane, compare the arrow, the pivoting being effected by means of a pneumatic cylinder 49. An elongate heel 61 in the table 50 extends a plate displacer 47, which by means of a pneumatic cylinder 48 is movable in the axial direction. In station V, at the "start", the plate displacer 47 is moved to the right in the drawing by means of the pneumatic cylinder 48. their new stations. In this way, the plate 51 arranged thereon is moved from its horizontal position to a vertical position and the plate can drip on its way to its next station VI, which is the weighing and control station.

In station VI, the filled plate is weighed. For this purpose, moldings 15, on which the suspension flaps 4 lie, are connected to a path 53 via a rod 52.

The scale checks whether the actual weight is within the set limits 54 and only then starts the automatic subsequent start.

From the station VII, the buffered plates can then be removed.

The transport system is designed in such a way that for transporting plates of different lengths, only the fixed mounting of the fork head on the cylinder 19 in the station I has to be changed. This provides a great deal of flexibility, since for a conversion of, for example, to shorter plate types, only two bolts 44 need to be moved to the holes 62 which are assigned to each plate length.

When the automatic cycle is started, a pneumatic cylinder 1 pushes on the left end of the machine frame via a jumper 2, round bars 3 to the right, which bars are internally parallel to the profiles 57 and 58. The round bars are connected by means of carrier blocks 4 and S and flat iron 6 gripping rails 7, which are also arranged on the inside and parallel to the profiles 57 and 58 a short distance above the working plane of the machine frame.

During feed, a pneumatic cylinder 8 rotates the round bars so that by means of pins 9 attached to the round bars 3, the carrier blocks 5 and the gripping rails 7 attached thereto are lifted. described cycle was also lifted. When the pneumatic cylinder 1 has been fully advanced, the gripping rails 7 are lowered by means of the pneumatic cylinder 8 and claws 12 arranged on the rails grip via the flaps 13 the pipe plates lying in the individual stations. By means of the return cylinder 1, six plates are transported at the same time to each of the next stations. When the screws 10 are not fixedly connected to the plate iron 6, on returning the angles 11 by means of rods 16 and the mold plate 17 can be lifted above the plate hanging from the weighing station, while the plate iron 6 is held down. The transport of the pipe plate 14 hanging in the draining station V is not effected by means of a clone but by means of the end of the plate displacer 47. The further transport in the buffer station takes place by means of the sliding angles 11, which are held up by the rods 16 and the mold plates 17. 16 inserts the oblique angles ll the weighted plates into the plate buffer 18.

All movements are coordinated and are in a functional connection with each other via a control center. 454 632 12 When the non-automatic cylinder 19 has returned to its initial position, all the described functions 1 run out of the individual stations. After going through all the functions, the gripping rails 7 are lifted and the machine returns to the initial position. The automatic tube plate filling machine enables high productivity and at the same time great flexibility by switching to different plate types. The machine is service-friendly and provides an even quality 10 on the armor plates through the blow-free filling and a uniform filling weight. This is ensured by a 100% control in the automatic weighing and control station. It is also possible to further support the filling of the paste by patting, shaking, vibrating or ultrasonic exposure. Finally, the machine works with high profitability and productivity.
