Description

Packaging machine The invention relates to packaging machines of records of conventional thin disc shape (hereinafter referred to as records designated) or other similar objects.

The usual shape of a container that records are packed in, is a so-called "envelope", which essentially consists of a square envelope made of cardboard, usually without a flap (i.e. open along one edge). Recently, improved shell shapes have been developed in which at least one the closed edges has a rib, i. e. a narrow wall in the right Angle to and connected to the major surfaces of the envelope. Such ribs can only be provided along the edge that parallel to the open edge lies or along all three closed edges or (if a closure flap is provided) along all four edges and these ribs contribute to the Reinforcing sheath and they increase the protection of the one inserted into the sheath Record is given and ultimately they create a surface that supports it is suitable to be printed with a title or other identifying features which should be visible when the records are stored in cases, which are placed in the usual way side by side on a wall board for example. One Ribbed envelope generally consists of two leaves. Examples of such cases are disclosed in the German patent specification (P 17 97 005.7-51).

Until now, records were largely packaged in sleeves by inserting the records into the cases by hand. Object of the invention is to od a machine for more economical packaging of records.

To create objects.

According to the invention is a packaging machine for records or the like. Articles created, the first feeding means for feeding one at a time first row of casing sheets through a lead-in zone to a merger further comprises record feeding means for arranging records one by one in the infeed zone, the record feeding means being arranged so that they work synchronously with the first feeding means, so that every Record is placed in the lead-in zone at a time that one sheet the first row is in the lead-in zone, so that the record is on This leaf is picked up and riittel for the release of hull leaves of a second Row individually to the unit synchronized with the arrival of the Sheets of the first row, the combining device being designed in such a way that that each sheet of the second row is attached to the one arriving at the same time Sheet of the first row, so as to form a complete envelope that the one previously on includes the record arranged on the sheet of the first row.

The leaves of the two rows can be of such shape that they each form the front and back sides of complete envelopes, and they can are printed (before delivery to the machine according to the invention) with such Illustrations or other printing as desired.

For the sake of simplicity, the sheets of the first row are shown below as the back pages and the pages of the second row as "front pages" designated.

It is preferred that each back sheet be stationary in the lead-in zone is in place while the record is being ejected; for this purpose you can the first supply means comprise a conveyor which moves intermittently and is arranged to feed the back sheets to the lead-in zone, as well as another sponsor, preferably one continuously running conveyor that holds the back sheets (on each of which is a record is located) carries from the lead-in zone to the unification facility. Alternatively the first feed can have two continuously running conveyors, both of which have pusher for moving the back sheets, one of the Conveyor each sheet to the lead-in zone and the other the sheet (and a record) transported from the lead-in area to the unification facility, where the relative timing of the two sponsors is chosen so that, after each sheet is advanced from the one conveyor onto a stationary surface In the lead-in zone, the sheet can remain stationary on the surface for one short period of time before a pusher from the other conveyor attacks the sheet to demonstrate it further.

Preferably the back sheet is flapped along it all four edges and the machine has folding means around the flaps at three To fold the edges to form ribs, as well as surfaces on which the front sheet ih the unification device can be attached, further to the flap on the fold the fourth edge to form a rib and a flap z-u. the The machine expediently has a feed container for holding a supply of backing sheets, Removal means for removing the back pages individually from the storage container and an input conveyor, on which the release agents each sheet when it is removed from the storage container, the input conveyor the leaves are transported past ploughters that have flaps at the edges (hereinafter referred to as upper and lower margins, with the upper margin being the margin with the closing flap) is parallel to the direction of movement of the input conveyor wrinkles. Then the flaps on the remaining two edges (as Side margins) and it is preferable that after folding the position of the sheet should be separated relative to the top and bottom margins to its direction of movement, so that the top and bottom edges in the following lie at right angles to this direction of movement. It is preferable to make this change of alignment to perform by placing the input conveyor at right angles to one Conveyor of the first feed means is arranged so that upon transfer from the input conveyor on one conveyor each sheet changes its direction of movement while aligning of the sheet remains unchanged relative to the fixed parts of the machine, because this arrangement helps to make the machine compact in plan.

But when. an elongated machine in plan is acceptable is, the aforementioned one conveyor of the first supply means can be used as an input conveyor serve and in this case means are to be provided for rotating each back sheet at a right angle after folding the flaps at its top and bottom Margins.

In the preferred embodiment with an input conveyor, the at right angles to an intermittently rubbing conveyor of the first In order to extend the means, the folders for the side margins of each subsequent back sheet must be provided work while it is resting and therefore are floating butterflies provided adjacent to the intermittently moving conveyor of the first feeding means.

The dispensing means for the front sheets normally have another reservoir, essentially the one for the back sheets corresponds and also has peeling means for peeling off individual sheets This further storage containers can, if desired, be close to the combining device be arranged so that the stripping means deliver each sheet directly to the latter. However, it is preferable to close a container for the front sheets that for the back sheets with one or more conveyors so arranged are that it synchronizes the front sheets and back sheets Feed the unification device, do h. that when each face sheet is from the Storage container is withdrawn, a back sheet from the corresponding storage container is peeled off and that these two sheets unite at the same time reach. While this arrangement can add to the cost of the machines it has but work advantages insofar as the two storage containers are close together and easy loading of the storage bins from a single one Operator can be done and (which is more important).

It is then easier to ensure that individual front and back sheets, which are to be united properly fit together; the requirement that the sheets fit together properly, results from what is usually on the front and back Is printed on the back of a record sleeve - usually the front and on the back the title and catalog number of the record packed in the case and this data is accompanied by a picture on the front and on the Back with a description.

It is preferable to equip the machine with means that are automatic Check that the record and the case fit together correctly, i.e. the picture and / or descriptive imprint on each sheet belonging to the plate included in the The envelope is to be packed which is to be made from the two sheets. For this purpose, it is advisable to provide each sheet with a coded marking, which can be easily read by reading means which form part of the machine; such reading means can be, for example, photoelectric or electromagnetic means and the markings can be made on parts of the sheets that are obscured are when the leaves are united to form the envelope. Accordingly, the records can be marked, but it is preferable to put such markings on pallets, on which the records are brought to the machine.

Checking sheets and records can influence the Machine can be exploited in different ways; as long as the markings on the Sheets and records (or record pallets) belong together correctly, then no interference with machine work is required, but if one If it does not belong together, different consequences may be necessary, e.g. the machine can be stopped and a visual or sound alarm can be triggered will. The currently preferred arrangement is that an encoded identification the record to be packaged is fed to the test equipment Manual operation of a control or switch panel, and that the test equipment is then at the work of the machine signals from various reading means with one stored Compare the reproduction of the coded identification mentioned. When a signal from the reading means for either the first or the second series of sheets, which Reading means read the markings on such sheets when they are out of their storage container subtracted, an ad triggers based on the comparison that no match is present, then the test means emit a control signal that at least a deflection causes the sheet in question in a reject container. In practice it can It might be useful to divert both sheets of paper into the reject container, as there is something one-shallow is the synchronization in the feeding of two rows of sheets maintain.

Markings on the record pallets can be determined by reading means when the pallet is moved into the machine and when there is a mismatch when comparing a signal obtained from this reading with the stored one encoded identification is determined, then a control signal can be emitted become disconnection agents by way of the record palette to cause the disconnection means prevent the record pallet from being discharged reached in the machine; so the records on this pallet are not in the machine can be introduced for the purpose of unpacking. In any case it is desirable generate a visible or audible signal whenever there is a mismatch is detected so that an operator will be aware that it is necessary is to put a new supply of sheets or records in the machine, to re-initiate normal operation of the machine.

Obviously, it is desirable to ensure that each of a machine made according to the invention case contains a record. In essence, this can be achieved by arranging the record supply means so that a stack of records is held adjacent the lead-in zone and that a record is removed from this stack for delivery as soon as a sheet of the first row detected by a test device in the lead-in zone will. This stack of records adjacent to the lead-in zone serves as a one Type of buffer stock and the record feed means lead records to the stack with greater speed than that with which leaves in the zone of union -Arrival, and further means are provided for the number of records in the Detect stacks and stop feeding further schail plates if one Desired maximum number of records is contained in the stack. However it is better to also check that each finished case also contains a record and for this purpose the machine can have a weight checking device which Receives cases from the association facility.

The preferred arrangement of the record feed means that just allows an intermittent flow of records into the Machine without interrupting its operation. This is beneficial as it is desirable is to check the records before they are packed. Part of the records generally has surface defects or other defects and they can be checked and faulty plates can be rejected before they are put into the machine enter. Preferably, however, the machine has a test device and the Record feed means offer the records one after the other to this testing device and only add those records to the stack that have been found to be faultless and divert defective records into a record reject bin.

The record feed means can be designed differently. The records are preferably received in stacks on pallets, with the pallets e.g.

have a base essentially in the form of a circular disk, whose diameter is slightly larger than that of the records to be carried, whereby this base carries an upright vertical column in its center of a diameter that fits into the center holes of the records. A pile conveniently contains fifty or a hundred records and are usually metal ones Support disks arranged at regular intervals between adjacent records, E.g. five or ten plates apart. The record feeding means therefore expediently further means to determine the presence of such Supporting disks and separating them from the records. Also can such Detection means include an electronic detector that points to nearby Metal appeals.

It is common to put each record in a paper or plastic bag before it is inserted into the envelope and the machine can therefore means have to insert each record into such a bag before putting it on a sheet is delivered to the lead-in zone. Such means include expedient a bag feeder removes the individual bags from a storage container and moves each bag in turn to a location adjacent to the introduction zone, where each bag from a bag opening device is opened while a record is being inserted.

The opening means preferably consists of a pair of eccentric ones Rollers that are driven in phase so that if there is a leading edge of each bag enters between the rollers, the surfaces of the latter are close together, while, when the bag continues to run between the rollers, their surfaces change separate. The bag is arranged relative to the rollers that a side edge The leading edge of the bag is when the bag enters between the rollers and therefore the top open edge of the bag runs between the rollers at one end same through.

At this end, both rollers are with holes around their perimeter provided and a suction chamber, which is assigned to each role, allows suction to the Holes take effect as they pass between rollers, so when each roll revolves, the holes that are directed towards the other roll (and therefore are adjacent to the bag), are subjected to suction at all times and the front and the back of the bag are therefore against the roles of atmospheric Pressure held. When the rollers rotate like this and the distance between them towards the surface increases, so the front and back of the Bags increasingly moved away from each other. The record supply means give a Record between the rollers when they are in or near the Position in which their surfaces facing each other are furthest are separated from each other and the record moves parallel to the axes of roles when it is handed in.

First, the paths along which hull leaves are described are described and move records through the machine, indicating the work, which are carried out at different points, based on FIG. 1.

As can be seen from Figure 1, there are two stacks 1 and 2 of casing sheets providedO In stack 1 are the sheets as they are fed to the machine, all screened, perforated, and printed with what on the back a finished envelope should appear and therefore the sheets are in this pile and which are fed from this stack, in the following as back sheets'? designated. For appropriate reasons, the sheets in the stack 2 and the out taken from this stack are referred to as "Vrderseitenblätters". leaves are synchronized from both stacks and fed individually along horizontal paths. The back sheets from stack 1 are fed down slightly and the front sheets from stack 2 are fed slightly upwards, so that the path along which the the latter move, located in a higher plane than the path along the back leaves of which move, the two paths also being laterally of each other are removed, as are stacks 1 and 2. While the back sheets are moving continuously move away from the stack 1, their edge parts are folded along the two edges that run parallel to the direction of movement of the leaves. To this Way is a back sheet that has just left stack 1, and that with the reference number 3 is provided, lie flat, while a sheet that is already has moved over a certain distance and is provided with the reference numeral 4, already having folded edge parts. Immediately after completing the desired folding process at the edge parts each of the successive sheets reaches a position 5, in which it does not move further away from stack 1 and almost immediately afterwards will cause the sheet to intermittently move at right angles to its previous one Movement direction begins to move. As this intermittent movement progresses, the edge parts of the sheet that are now the page margins are relative to the new one Direction of movement of the sheet partially folded so that after moving over a certain distance in the new direction and reaching position 6 every four edges of the sheet are at least partially folded.

At this position 6, which is one of the positions in which the back sheet stops for a moment in the course of its intermittent movement, becomes a Record placed in an inner bag on the back sheet. In the continuation its intermittent movement runs the back sheet against a stop a point 7. From the point 7, the back sheet is continuously in the same Moved towards a location 8, completing the folding of the side edge portions when the back sheet moves between positions 7 and 8.

Returning to viewing the face sheets that are from the stack 2 are fed, these sheets follow a path essentially that of the Back sheets correspond, but they are not subjected to folding processes. In this way, the front sheets run away from the stack 2 until they come to a position Reach 9, at which each face sheet momentarily stops and then again begins to move, but in a direction at right angles to the direction of his resulting movement. While each face sheet changes from the position 9 moved away, it runs horizontally in the same direction as the back leaves, which leave position 5 (but moving continuously, not intermittently like the back sheets in this area) and along a path that is vertical is aligned with the path of the back sheets leaving position 5, so that the front sheets pass over positions 5, 6 and 7. But when each Front sheet by a position 10 above the position 7 runs in the path of the back leaf r, it begins to move downward sloping, so that the leading edge of each obverse sheet is the leading edge of a corresponding one Back sheet meets while the latter comes to a position 8. The two Sheets then move further together as a complete envelope, with glue serves on the edge parts of the front sheet to the back sheet and the To attach face sheets together to form a complete envelope. The adhesive is applied to the side edge portions and the lower edge portion of the face sheet applied as it is sloping downwardly from position 10, i. very shortly before the front sheet meets the back sheet, while the latter moves through position 8.

The complete casings, which are formed in such a way, each contain a record and move on in the same direction to one Position 11 and then along an arch-shaped path, as indicated at 12 (where they run through a position where the weight of each case is checked) and then horizontally further to the buffer stack 13.

From the stack 13 are the complete records containing records HUllen individually challenged by positions 14, 15 and 16 one after the other; on these In the latter positions, an outer shell is attached and then the complete Cases led to a lower stack 17, from which they are removed in groups can, as indicated at 18, as required.

Returning to position 6i, it is reminded that here - a record was placed in an inner bag on each back sheet. The records so fed enter the machine in stacks on pallets, such as indicated by reference numeral 19 and these pallets become a position 20 guided, from here an operator (not shown) can as required every.

Move stack into an insertion position 21 and be in this position Record one at a time from the top of the stack and close it horizontally a buffer store 22 out. The lowest record in the supply 22 can become something move downwards and is then in an arc-shaped path through positions 23, 24, 25, 26 and 27. At position 23, the surfaces of the record are cleaned and the record is checked for evenness and concentricity and then the record is made subjected to further tests at positions 24 and 26, initially on one of them Surfaces and then on the other if the results of such tests are satisfactory are, the record is from position 27 horizontally in an inner bag 28 inserted and can then move down onto a buffer stack 29. This Stack is held adjacent to position 6 and the lowest record in each case this stack is delivered when e-in; tuckseitenblatt at the position 6 stops 0 The inner bags are moved horizontally from a feed position 30 to the position out, in which the bag 28 is shown, with the pouch underneath run the way of front sheets exiting position 9 and above the way of Rüskse} ten leaves that leave position 5.

Figure 2 shows the machine in which the above-described operations are carried out and the reference numerals used in FIG. 1 are used as far as possible also used in the description of FIG. Different parts of the machine according to Figure 2 are shown in detail in other figures and will be discussed later described.

The machine shown shows two supply containers 51, 52 which contain the stacks 1 and 2, respectively. In the containers 5i, 52 the leaves lie in planes which are slightly inclined with respect to the vertical (as can best be seen from FIG. 1) and each of the containers has a mechanism, not shown in detail in FIG. 2, for removing individual ones Sheets from the bottom or the back of the stack. In the case of the container 51, each sheet is removed by moving it back and forth so that it exits horizontally moving onto a horizontal conveyor belt 53. In the case of the container 52, each sheet is removed from the stack by moving it upward and is guided so that it moves horizontally moving, arrives at a horizontally extending conveyor belt 54, but at a higher level than that of the belt 53. The conveyor belts 53, 54 serve to move the back sheets and the front sheets to the positions 5 The straps 53, 54, however, end somewhat before the points 5 and 9, so that when the leaves reach these points, they have moved away from the straps.

The machine described here produces finished casings of the Att, which has a so-called rib along each of its four edges. With rib is meant a stiff narrow wall between the front and the back of the shell and essentially this is produced by first overfolding an edge part of the back sheet and attaching it with adhesive the same on the next part of the sheet on which it is pressed, and then-again taking place overfolding the edge part now of double thickness, around both the rib as well as a tab parallel to the main surface with which it is integral is trained.

As emerged from the preceding description of FIG in the present case the ribs are formed on the back sheet, while the front sheet is essentially square and the size of the finished shell. Ribs are formed, as just indicated, along three of the edges of the back sheet, while along the fourth edge a rib is formed and a closure flap, which in the finished case is not attached to the face sheet by means of adhesive is, but is only struck.

This rib and flap are of simple-thickness in order to be more bendable to be. The edge of the sheet and the envelope on which this closure pocket is located is in the following referred to as the upper edge and the opposite Edge becomes ale lower Edge denotes while the remaining Margins are referred to as page margins.

The back sheets are placed in the tray 51 with theirs upper margin 2rn. to the right when looking at Figure 2. Correspondingly, there are the top edge of each back sheet as it travels along conveyor belt 53, still on the right and its lower edge on the left and this are the edges parallel to the Direction of movement of the sheet at this stage, which is subjected to a folding process while the sheet is on this conveyed item. The first will fold effected by a set of plow folders 55a (which are only needed for the lower edge because the flap at the top is not twice as thick), while the second folding process to produce the rib shape is effected by mechanisms contained in the housings 55b. For proper formation along the rib the lower edge it is necessary to apply glue to the edge part, of the sheet ver To apply the folding, and an adhesive applicator 56 serves this purpose.

As mentioned in connection with Figure 1, the front sheets require no folding and no glue application at this stage and therefore how on The drawing shows that there are no folding devices or glue applicators assigned to the conveyor belt 54.

Both belts 53 and 54 run continuously, but when the back sheets to position 5, they will be at right angles to their previous one Moving direction moved away to position 6, ie. generally to the left when considering of Figure 2, by an intermittently moving conveyor. Appropriate this is designed as a pair of belts or chains, both below of a slot in a smooth plate along which the leaves slide can, with the chain or strap wearing pusher links passing through the slot protrude and attack the upper edges of the sheets to be conveyed, the top margins at the back of the sheet in relation to its new direction of travel lie0 This intermittently moving conveyor is not in Figure 2 visible but of a well-known type and is referred to as the second sponsor When each leaf reaches position 5, it runs under a downward direction Brush through gently pressing down on the sheet while it is in position 5 stands still for a short time.

When the sheet starts moving with the second conveyor, it stops this brush ensures that the blade stays in contact with the pusher links, which push it forward and when the top edge of the sheet (which is now in relation on -; the new direction of movement is located on the back of the sheet) under the Brush passes through, the latter causes the previously folded over upper edge part is unfolded again0 This Work process is not hindered by the pusher links that grip the leaf near its SeivenrGnder while the upper edge part, which is folded over and is now being unfolded again, does not move extends over the entire width of the sheet.

As each back sheet is advanced by the second conveyor, run its side edge parts (which now extend along -the soites that in Direction of movement are) past adhesive on application devices, of which one, 57, is visible and which is in relation to the side margins to the same Purposes serve as the adhesive on application device 56 in relation to the lower Edge, i.e. for applying the adhesive required to ensure that the edge portion, which is then folded over, by mechanisms in the housing 58a Forms a double strength to provide the required rigidity in the doll's finished product To yield envelope. The side edge parts were not further folded before the back side sheet the position 6 is reached and the folding is only completed at a later stage.

Preferably, the first folding operation is performed on the side edge portion, the was just mentioned, while the second conveyor stops. Therefore wise the rlechanismen in the housings 50a movable folding blades on the edge parts of a stationary leaf act.

At position 6, as already mentioned in connection with FIG. 1, each back sheet is temporarily stationary and at this point one is already Record enclosed in an inner bag and placed on the back sheet. At this point, the top and bottom edge portions of the sheet are already formed (but the upper edge part is unfolded again and the lower edge part becomes partial unfolded its infoloe of its own elasticity), while the margin parts have only been provided with glue and subjected to a first stage of folding i.e. to create a double thickness in preparation for forming the Rib on each side edge; This way, putting the record down is through hindered several of the edge parts.

After placing a record on each back sheet in the position 6 this sheet continues in the same direction as it did immediately before arrival at position 6, and the upper edge part is again folded over by a Pair of hook-like fingers that are moved upwards from below the path of the Sheet along an arcuate path to engage the top edge portion of the sheet and bring it back into the folded position. This prevents the vinyl record remains in position 6 by sliding off the back sheet when the latter is moved away from position 6 by the pusher members of the second Conveyor, and for further safety is a horizontally movable one Link (not shown) provided2 that the upper Edge part during of the initial part of the movement away from position 6.

From position 6 the sheet is moved to the position by the second conveyor 7 moves. Here, each back sheet, when it arrives, is replaced by another or Third sponsor attacked, whose work begins at this point. This third conveyor can be described as consisting of a series of pockets, each of which can accommodate a back sheet. The leading and trailing margins Each pocket is made up of pin-like links that are at right angles extend to the direction of movement of the blade and have overhanging flanges, which attack the top and bottom edge portions of the leaves and fold in properly Hold positions. The third conveyor moves continuously.

When the back sheets are advanced into the pockets of the third Conveyor run past the butterflies for the side edge parts of the sheets to shape the ribs, a set of such folders is contained in the case 58b in FIG. 2. It should be noted here that the folders in the housing 58b correspond to those in the housings 55b, since they have to do the same work on the side edge parts of the back sheet like the mechanism in the housings 55b on the upper and lower edge parts, the leaves in both cases being are in continuous motion past the sliding mechanisms.

During all the above-described operations on the back sheets are the face sheets being delivered by conveyor 54 to the position 9, above the back sheets on a further conveyor 59 run and when each back sheet leaves position 7, a corresponding Front sheet passing over it discharged from the conveyor 59 into a case u0, which includes a conveying mechanism to incline the face sheet downwardly so that it meets the back sheet in alignment.

Once the marginal portions of the back sheet are properly folded the back sheet is ready to receive the front sheet. If any Front sheet inclined downwardly moving within housing 60 becomes adhesive applied to the lower surface of the face sheet over areas that his bottom and side margins are adjacent. This glue applicator is not shown in Figure 2, but corresponds to an offset printing device.

This feeding mechanism (not visible in Figure 2), which is the top sheet inclined downwardly advanced within the housing 60, can be configured differently be; preferably a pair of drive rollers are provided between which each Front sheet is gripped one by one and forcibly fed along of the desired inclined path to such an inevitable control the position of each face sheet. These rollers are with circumferential grooves provided and narrow and arranged so that they grip the sheet along lines, on which no glue has been applied. The position of each back sheet is of course precisely determined, since it is still in a pocket of the third sponsor is included. The feeding of the front pages is precisely timed, so that each face sheet meets a back sheet in precise registration.

After the two sheets have come together to form a complete To form the casing that is still running on the third conveyor, the finished casing, that the record contains in its pouch, apply sufficient pressure to a good bond between the adhesive-covered areas of the front sheet and create the bottom and side lobes of the back sheet. Becomes expedient Such pressure is exerted by a series of feather pillows that are a pair of straps press against the surface of the sheath that goes underneath, using the straps run at the same speed as the third conveyor and with the cushions preferably work surfaces have such a shape that a pressure is not over the whole area of each envelope is exerted, but only over the areas within whose adhesive is located.

A final conveyor (not visible in Figure 2) under the housing 60 takes the finished casing evuf when it runs off the third conveyor, and this one last conveyor works continuously at a higher speed than the one with which the third conveyor moves so that when each finished casing is sufficient ran onto the last conveyor to be driven by Shm, it accelerates and is moved away from the flange rod that is the trailing edge of the Forms pocket of the third conveyor in which the back sheet ran so that the trailing edge of the finished shell is free from this flange rod before the last-e begins to slope downward, causing possible damage to this trailing Edge of the envelope is prevented.

The finished records containing records are taken from the last conveyor Cases dispensed into a weighing test unit 61. This unit has a rotatable Assembly 62 which receives successive envelopes angularly from one another distant radial positions. Sede filled shell enters this arrangement horizontally one and the arrangement drifts, so that the shell then over an arched way is rotated around 1800 and at that point then usually by any Ejector is ejected to position 13. While each filled shell is in of assembly 62, it travels through a position in which it is vertical is held and this is the position that each envelope is placed on a weighing mechanism rests. When the weight of the filled envelope is approximately correct, then the envelope is delivered to position 13, but when in the vertical position the case is found to be too heavy or too light (and if so indicated will. that the case contains no or more than one record) then works the weighing mechanism so that it prevents the casing from the rotatable assembly 62 is dispensed when it is adjacent to the position 13., And the envelope is then back-cooked in assembly 62 until the envelope is directed downward and then it is released into a reject container in the lower part of the unit 61.

From position 13, the filled casings run into a wrapping device 63, which is not described here in detail because it does not belong to the invention, it is disclosed in the German patent table - (P 18 11 902.3-27)., Von of the device 63 are stacks of wrapped filled casings, such as the stack 18, received.

In the preceding reference was made to the storage of a record, which is enclosed in an inner bag, onto the back sheet and it will now described how the record, which is so enclosed, is in the position is brought, in which it is deposited on the sheet.

First, the inner bags are placed in the machine in position 30 introduced (shown in both Figure 1 and Figure 2) and run along one conveyor below conveyor 59 and above the second Conveyor to a position that is adjacent but is at a higher level is located as the position 62 in which the record in its bag on the back sheet When each bag reaches the left end of the conveyor that is delivering it so feeds, the open end of the bag 9 becomes that away from the viewer of FIG is directed, kept sufficiently open so that a record is in the bag can be inserted and the bag, which now contains a record, falls slightly downwards onto the buffer stack 29 (FIG. 1).

The records enter the machine on a conveyor 64, where the records expediently, as shown, in stacks on pallets and each pallet has a base plate 65 and a central column 66. The conveyor 64 releases the loaded record pallets onto a table 67 and from here an operator moves the stacks of records with their pallets as required in the insertion position 21 (FIG. 1). As shown in Figure 2 As can be seen, two stacks of records can be arranged at position 21, Side by Side In FIG. 2, a complete stack 68 is in the insertion position and a nearly exhausted stack 69 shown immediately behind. lily further As shown in Figure 2, the machine takes peeling plates from the nearly exhausted one Stack 69 on, with the 3 records removed from the top of the stack will and be guided in the direction of the viewer. At the position 21, each of the stacks 68, 69 is placed on a support platform which, during the Records are removed from the stack, increasingly being raised so that with decreasing height of the stack, the top record in the stack, from the records removed, is held in the same plane so that the one above it mechanism you can take away.

The records are pushed horizontally, with their outermost Marginal parts taken in channels, at two diametrically opposite points, to a test unit 70.

While feeding sound bars from stack 69 (or stack 68) The test unit 70 is made of metal support disks from the sequence of records, which were in the stacks on the pallets, removed. Expediently happens this by means of a magnetic or capacitive test device directly above the path of the records, the part of the channel section in which the record edges run whenever the testing device detects the presence of a metal washer indicates that they should be slightly removed from each other immediately adjacent to the test equipment, so that the metal disc can fall out. A container, not shown, can be placed below this point to accommodate such disks.

Because of the removal of the metal discs, there are gaps in the record sequence, approaching the unit 70 *. Therefore, the records of the unit become closer faster -delivered than is absolutely necessary in view of the speed, with which they are handled in this unit and at a position 22 (Fig 1) A small pile of records is collected with the records on top of the stack are fed and removed one at a time from its bottom. This small pile then acts as a buffer store.

At various positions in the machine described here it is advantageous to provide means for checking that the records and Sheets fit together properly. The sheets can be provided with coded markings be, preferably on parts of their inner surfaces, so that such markings occur of the finished shell are not visible. Correspondingly coded markings can to be attached to the records, but it is preferable to rely on markings to leave on the record pallets. These markings can be used in any case be such that it can be checked by photoelectric or electromagnetic testing equipment can be read and such test devices are preferably at e.g. located where leaves leave the storage bins 51, 52, and at the positions 20, 21, where loaded record pallets enter the machine. Electronic Circuits with which these test facilities are connected, then give warning signs when necessary. Need such circuits of course, storage facilities for the output signals of the test equipment To bridge time differences if you want to compare signals from two Test operations are obtained that cannot take place at the same time.

Various parts of the machine described will now be described in detail described. the drawings, on the basis of which the individual parts of the machine are explained sometimes show parts that are also shown in Figure 2, but with different ones Reference numerals, the easier it is to point out the figures, the special features best represent for their description.

First, the sheet feeding mechanism for Trays 1 and 2 is set (Figure 2), specifically with reference to Figures 3 to ZC.

As can be seen first from Figure 3, the feed mechanism has two Containers 701 and 702 arranged side by side on a base plate 703 are. A housing 704, the drive belts, is located between the containers 701, 702 for the mechanism in each container, remove the cardboard sheets from it can, as will be described in detail. the Feeding device, which is shown here is preferably used to simultaneously zuei-leaves feed, i.e. one sheet from each container 701, 702, to a machine for Manufacture of Record Sleeves, the sleeves are made from a front string reed and a back sheet which are combined together to form a finished case to build. The back sheets are arranged on edge in the container 701 and the Front pages upright in bin 702, with front pages individually are fed in upright orientation to a horizontal conveyor 705 and the back sheets individually, coordinated with the front sheets, into one Horizontal conveyor 706, which is lower than the conveyor: 705.

As can also be seen from FIGS. 3A, 3B and 3C, the containers are made of iron 701 and 702 each have two side walls 707, 708 and 707a, 708a, furthermore one each. Back wall 709, 709a, a lower wall 710, 710a and an upper wall 711, which are extends across both containers with the lower walls attached to base 703 are.

A stack 712 of backing sheets is stacked in bin 1 Pair of base plates 713 carried, only one of which is visible in Figure 3B, which are carried at their ends on rods 714 extending between the side walls 707, 708 extend and are attached to these at their ends. the pages of the stack 712 are controlled by side panels 715, only one of which is in Figure 3B is visible. A stack 716 of face sheets is supported in the Container 702, like the stack 712 in container 701, on base plates 717 and rods 71S carried between the side walls 707a, 708a thereof will.

The containers 701 and 702 and thus the base plates 713, 717 are mounted on a base 703 so that both stacks of sheets are supported in one plane which is slightly offset from the vertical, as shown in Figures 3B, 3C can be seen. The top of the stack 712 is supported by two blocks 719, which engage the leaves near their upper corners, as shown in Figure 3; to see. The surfaces of the blocks 719 that engage the blades are angled, as at 720 can be seen in Figure 3B. A small lug 721 is on the right end, when viewed of Figure 38, the plates 713 are provided to the bottom corner of the stack 712 support.

The top part of the stack 716 is supported by two freely rotatable ones Rollers 722 which engage the foremost sheet at locations shown in Figure 3A. Two protrusions 722a are also provided against which the top corners of the leading The sheet. The underside of the leading sheet in the stack 716 rests against two blocks 723 which at the right end when viewing Figure 3C of the plates 717 are attached. The fronts of the blocks 723, which the leaves attack are angled, as can be seen at 724 in Figure 3E.

A nipple 725 (Figures 3A and 38), with a single suction pad 725a, is used to attack the leading sheet near its lower edge, in the stack 71-2, and rollers 726 driven by it in a manner still to be described feed, which cooperate with resilient rollers 727, 728 to the Guide sheet to horizontal conveyor 706. The rollers 726 are on a shaft 729, which is carried between the side walls 707, 708. The roles 727, 728 are freely rotatable at one end of arms 730, 731 which are attached on axially aligned shafts 732, 733 (Figure 3A). The waves 732, 733 are rotatably mounted in a bracket 734 which is fastened to the lower wall 710 is. The rollers 727, 728 are pressed against the driven rollers 726 by means of springs, one of which is shown at 735, in Figure 39 ~. Another lever 736 that is on is attached to the shaft 733, carries an adjustable stop 736a (Figure 38), so that the gap between roller 728 and the cooperating driven one Roller 726 can be adjusted to any desired distance, e.g. to a distance which is slightly below the thickness of a single leaf. Also on one At the end of the shaft 733 is a lever 737, - the other end 738 a Microswitch 739 can operate if two sheets are released from the suction unit 725 at the same time which would then cause the rollers 727, 728 to separate from the Move rollers 726 away.

One of the arrangements described in the previous paragraph is provided in the container 2 and shown in Figures 3A and 3C. The device is largely the same, apart from the suction cup 725, which, as can be seen from Figure 3A, consists of a pair of suction pads 725a arranged side by side. It are the same designations used in Figures 3A and 3C for parts that use the are the same and serve the same purpose as those that are based on the figures 3A, 36 have been described. These parts are not described again, but it is it should be noted that in the case of the backing sheets in bin 702, the The apparatus is positioned so that the foremost sheet of the stack 716 is in an upward orientation, approx to the horizontal conveyor 705 wrd.

To the forward movement of the stacks 712, 716 to the respective suction cups 725, a device is provided in each of the containers 701, 702, which consists of a pair of strips 741 between the base plates 713 in the Container 701 and between the base plates 717 are arranged in the container 702, only one of these strips 741 being visible in each of FIGS. 3B, 3C. the Strips 741 are mounted on supports 742 which are mounted on eccentrically mounted shafts 743 are worn, which are constantly rotated during the operation of the device, in the direction indicated by arrows; when the shafts 743 rotate, give they give the strip 741 a movement that is circular with one Radius, which corresponds to the eccentricity. In this way, the leaves are constantly up- and moved away and pushed forward toward the suckers 725.

The mechanisms for generating the movement of the suction cups 725 to the feed of the sheets from the stacks 712, 716 are separate from one another, however essentially correspond to one another in training and working methods. The main difference lies in the fact that each of these two mechanisms is reversed with respect to the other is arranged so that back sheets from the stack 712 in the downward direction are conveyed away and face sheets from stack 716 in an upward direction. In the following description, the mechanism for moving the nipple 725 described in detail in container 701 and, in order to avoid repetition, when different reference numbers are used for corresponding parts in container 702 are, these in brackets immediately after the reference numerals for the parts in the Container 701 attached.

The sucker 725 is carried by a block 744 (744a), which in turn is carried by a tube 745 (745a), the block having internal bores for the purpose of connecting the cushion 726a and tube 745 so that suction is applied can be attached to the cushions 725a via a tube 746 (746a) that connects the tube 745 (745a) connects via a rotary valve 747 (747a) mounted on a shaft 748 (748a) with a suction source (not shown). The pipe 745 (745a) is fixed in a frame 749 which is supported by two pairs of levers 750, 751 (750a, 751a), with one lever of each pair on each side of the frame 749 (749a) is arranged. Only one lever of each pair is visible in FIGS. 3B, 3C In Figure 3A, the levers 750 (750a) are not visible because they are immediately behind levers 751 (751a). Pivot connections 752 (752a) between the frame 749 (749a) and one end of each of the levers 750 (750a) are provided, the other ends of these levers are slotted at 753 (753a). A pin 754 is attached between and supported by two seitan plates 755 (755a), the side plates are mounted on the rear wall 709 (709a) and the pin extends through the Slots 753 (753a). The levers 750 (750a) also carry a roller 756 between them (756a) which rides on a cam 757 which is attached to the shaft 743 (748a), which is rotatably mounted on the string walls 707, 708 (707a, 708a).

A spring 758 (758a) is arranged to contact roller 756 (756a) to hold with the cam 757 (757a).

The levers 751 (751a) also have a swivel connection at one end 759 (759a) with the frame 749 (749a) and are supported by a spindle 760 (760a), which erotrectot between the side plates 755 (755a). The other end of the lever 751 (751a) carries a roller 761 (761a) which rides on a cam 762 (762a) which is attached to a shaft 763 (763a) which is rotatably mounted in the side walls 707, 708 (707a, 708a). A spring 764 (764a) is provided to to keep roller 752 in contact with cam 762 (762a).

The mechanism in the container 701 will now be described. The shaft 748 carries, attached to it, another cam 764 on which a roller 765 runs, the is mounted on one end of a toggle lever 766 which is attached to a pin 767 is rotatably mounted in a bracket 768, the other end of the lever 766 carries a spring 769 to hold the roller 765 in contact with the cam 764.

An arm 770 attached at one end to pivot pin 767 carries at its other end a roller 771 which engages the surface of the leading one Sheet in the stack 712 and the weight of that stack from the extension 721 to determine Times decreases, as will be described later.

To remove the leading back sheet from stack 712 the shafts 748, 763 are continuously driven, as will be described later, so that under the control of cams 757, 762 and 764, the following sequence of operations is carried out will.

The pulley 771 is swung to the left as viewed from Figure 39 to pivot pin 767 to make contact with the leading sheet of the stack 712 and the lower tail of the latter slightly away from the extension 721, so as to decrease the weight of the stack from it at the same time the sucker becomes 725 swung to the left, looking at Figure 38, around the spindle 760 to attack and by means of Induced draft to keep the leading sheet in Stack 712 with suction being delivered to pad 725a at the correct time under control of the rotary valve 747. The sucker 725 then begins to swing away from the stack and thus pulling the lower part of the leading sheet away from the next sheet, past approach 721. While this is happening, roller 771 remains in the same position and the sheet is therefore caused to flex around the roller 771, so as to do so to help ensure that only one sheet is picked up by the absorbent pad 725a will. This bending of the sheet around roller 771 causes those edges of the sheet which contact the angled surfaces 72D of blocks 719 are pulled out the angle between the stack and blocks 719.

The faces 720 are angled so that once the leaves of the angle mentioned above are free, a leaf is only held by the sucker 725 and is in contact with the roller 771. When the lower edge of the The sheet is moved past the extension 721, the roller 771 is moved to the right at Viewing Figure 3B, so that the lug 721 in turn takes the weight of the stack i12 records.

Also at this time, the sucker 725 is moved in the downward direction.

The sucker 725 continues to guide the sheet downward until it is gripped between the rollers 726, 727 and at this point the suction is switched off and the nipple is moved upward to the position shown in FIG is. A sheet will of the rollers 726, 727 along a curved Guide plate 772 conveyed in order to then be gripped between and conveyed on to be held by a pair of cooperating belts 773 that make the horizontal conveyor 706 to another mechanism that does not form part of the present invention is.

The leading sheet of stack 716 in bin 702 is removed therefrom on the same track as just described with regard to stack 712 in container 701, except that the sucker 725 has the leading sheet near its top edge grabs and the sheet feeds up to the rollers 726, 727 after the upper part of the sheet passes projections 722a which are the same The purpose is like the extension 721 in the container 701. AuE ind the rollers 722. in the container 702 not movable like the rollers 771 in the container 701 but they are the same as those Purpose, namely to bend the sheet around rollers 722 and this bending causes that those edges of the blade that engage the angular surfaces 724 of the blocks 723 be pulled out of the angle between the stack and the blocks 723o Die Rollers 726, 727 in bin 702 grip and advance the sheet up and down a further guide plate 774 to a conveyor 773, which is part of the horizontal conveyor 705 and is not part of the invention Between the ends of the guide plates 772, 774, which are removed from the rollers 726, 727, and the Horizontal conveyors 706, 705 are other pairs of rollers 775, 775a, 776, 776a provided, wherein the rollers 775, 776 are driven and the rollers 775a, 776a be pressed resiliently against them. Adjacent to each of the last-mentioned pairs of roles is a deflector 777, 777a and these are shown in solid lines from FIG Position (see Figures 33, 3C) in the one shown in dash-dotted lines Position moved by actuating solenoids 778 and 77bs. The solenoids will both energized when one of the microswitches 739 is closed, namely more than one sheet at a time.

fed between rollers 726, 728 into either container 701 or 702 will. When the deflectors 777, 777a in the dot-dash position according to Figure 3B, 3C, the leaves are fed into hoppers leading to bins 780, 780a (see Figure 3), which are used to collect rejected leaves, the rejected sheets from bin 701 through hopper 779 and the rejected sheets pass from bin 702 through hopper 779a.

If at any time it should be desirable, the supply to interrupt from leaves, this can be done simply by switching off the induced draft from the suction cups 725.

It is not necessary to stop the movement of the various parts, since no sheet can be fed from one of the stacks while the sucker cannot work.

As already stated, a front sheet and a back sheet should fed from the containers 701 and 702 with each other at a later stage connected to form a record case. It is therefore important that. the two sheets fed together from the containers fit together, because usually at least one title is printed on the front sheet and the back sheet contains certain descriptions relating to that on the Record Recorded Record. For this purpose, both sheets can be identical Codings can be provided in such a way that the codings of testers 781, 781a readable (e.g. photoelectric or electromagnetic devices can), which are arranged in the containers 701, 702. Such an examiner is in each of the containers 701, 702 shown at 781 and 781a, respectively, and the arrangement is such that if one of the inspectors finds an incorrect coding, both solenoids 778, 778a are actuated so that both sheets are rejected in the same way, as described above with respect to feeding two sheets at a time from a container.

The various shafts of the feeder are suitable Gears driven by a driven unit 782 (Figures 3B, -3C).

Next, details of the mechanism for dropping a Record (in its bag) on each back sheet of baech9Reben9 based on of Figures 4 to 4Fo In Figure 4 is a partially formed back sheet 320 delivered to the position shown and has come to rest there, namely along a horizontal path in the direction of arrow A, by means of two fingers 104 carried on chain conveyors 105 intermittently by a drive unit (not shown) are driven.

As described above, sheet 320 is vertically below one Stack of records BR arranged in a record feeder 321 are worn. The records go to the top of the stack one at a time BR fed by a mechanism (not shown) that turns the records into introduces a bag, this mechanism being located above the device 321 is.

The device 321 has a base plate 322 and three side walls 323, the base plate 322 having a window 324 through which the in the stack BR containa panels pass through when successive panels from the bottom of the stack can be removed in a manner to be described.

The stack is supported within device 321 by three mechanisms 325, 326, 327, which are supported by the base plate 322 and are arranged so that that one of them is adjacent to each of three sides of the window 324, such as can be seen from FIG. 4A. The bag that contains each record is open along one side so that the record can be inserted and attached the side of the Window 324 facing the open side of the bag is located, no mechanism is provided as such a bag easily during could affect the separation of the bottom plate from the rest of the stack, like will become clear later. When the device should only handle records (i.e. if the records weren't enclosed in bags), so could such mechanisms are equally spaced around the circumference of the record be. Since mechanisms 325, 326, and 327 are identical, only the mechanism 325 in detail.

The mechanism 325 consists of a lower support plate 328 with a single finger 329 on top and a top support plate 330 with two fingers 331 on it (figure @@@). The plates 328, 330 are each at one end of rods K. 332, 333, which are slidably supported in bearings 334, 335, the latter one above the other in a lug 336 that extends downward from the bottom the base plate 322 extends. The other ends of the rods 332, 333 are as hoods and are in engagement with the surface of cams 337 and 338, respectively are attached to a shaft 339 which is mounted in the base plate 322, wherein the rods 332, 333 are held in contact with the respective cams by Springs 340 (Fiour 4C), which between the. At set 336 and collar 341 are mounted, which are attached to the bars. To prevent the 332, 333 in the bearings 334, 335 rotate, pins 342 fixed in the bearings are provided, which extend in longitudinal slots (not shown) in the rods the Shaft 339 and corresponding shafts 343, 344 of the mechanisms 326, 327 extend all up through base 322 with their upper ends rotatably supported are in. corresponding housings 345, which are on the surface of the base plate 322 be worn. Another shaft 346 rotatably mounted at one end in one Housing 347, which is also carried on top of the base plate 322, extends downward through the base plate and carries it at its lower end a bevel gear 348 which is in mesh with a further bevel gear 349 with a drive shaft 350 is connected, which is driven one revolution at a time through a one-turn clutch 351, which will be described later, the driving force thereof Link is continuously driven, in the manner indicated by arrow B (Figure 4B) Direction through an input shaft 352, which in turn is driven by a drive unit 152; the shafts 350, 352 are axially aligned with one another, and the shafts 339, 343 are driven by shaft 346 through toothed belts 353 and 354, respectively. The shaft 344 is driven by the shaft 343 by means of a further toothed belt 355.

The one-turn clutch 351 is shown in Figure 4B and exists from a driving member 356 which is firmly connected to the input wool 352, and a driven member 357 fixedly connected to the drive shaft 350 is. The limbs 356, 357 are both disk-shaped, with the limb 357 is of considerably larger diameter than limb 356. On the face of the disk 357 next to the driving member 356 is a block 358 is provided and a pin 359 on which an arm 360 is pivotably mounted.

The arm 360 is provided with a tail 360a and also a protrusion 361 provided which engages a recess in member 356 in FIG Way. The arm 360 is urged clockwise about the pin 359 by a spring 362. Swivels at one end on a shaft journal 363 parallel to the shafts 350 and 352, a lever 364 is provided which forms a hook 365 at its other end. Another lever 366 is also pivotally mounted at one end on the shaft 363 and is provided with a spring-loaded pusher 367 at its other end.

A handlebar 368 is pivotally mounted on the lever 366 near one end. The end of the handlebar 368 closest to the pivot point carries a spring 369 that controls the lever 366 counterclockwise around the shaft. 363 pushes, the lever 364 together is moved with the lever 366 by means of a flat spring '370 attached to the lever 366 is attached. The other end of the link 368 is at one end of a short arm 371 attached, the other end connected. is connected to the output shaft of a rotary solenoid 372.

On the top surface of the base plate 322 is a light source 373 and a photocell 374, which are arranged so that the light beam between both is interrupted from the stack BR. The photocell 374 generates a signal at such an interruption and this signal is used to supply in the Bag located records to the stack BR interrupt and this feed resumes when the interruption of the light beam has ended. the The height of the stack BR is therefore stabilized and the weight that is on the fingers 329, 331 does not become so large that it interferes with the functioning of the fingers would. Another light source 375 and photocell 376 are arranged so that they notice the presence of partially formed back leaves that are the rest position (i.e. the position of the blade 320 in Figure 4) below the device 321 approach. The source 375 and photocell 376 are arranged to produce a signal from cell 376 caused when a leaf is between source 375 and of cell 376 passes, solenoid 372 is actuated. This causes the clutch 351 engages and drives shaft 350 one complete revolution and is then released again, which in turn causes each of the shafts 339, 343, 344 rotate a full turn and then stop, taking the lowest record of the stack BR from the mechanisms 325, 326, 327 in a manner to be described is dispensed and falls onto the sheet below.

In Figures 4 and 4A, the sheet 320 has been delivered to the position shown and before it reaches this position, a signal that generated by the photocell 376 when the sheet 320 is between it and the associated Light source 375 passes through, communicated to solenoid 372 via a Delay device (not shown) any A'rt ,, so that the delayed signal the solenoid actuated when sheet 320 comes to rest. The resulting operation of the Solenoids 372 causes the levers 364, 366 to move from the dash-dotted line to the Move the position shown in solid lines (Figure 4B). This enables the Lever 360 pivots clockwise around pin 359 under the action of spring 362, so that the projection 361 engages with the recess in the driving Link 35, which the latter rotate continuously so that in this way the driven member 557 and thereby the drive shaft 350 rotate.

After the various parts of the clutch 351 has reached the position have, which is shown in solid lines in Figure 4B and the rotation of the driven member 357 has begun, the solenoid 372 is de-energized again at Termination of the delayed signal from the photocell 376 and the spring 369 moves the lever 366 back to its original position (shown in dash-dotted lines), the lever 364 being moved by the flat spring 370 in the same direction as much as possible, i.e., until the hook 365 engages the rim of the link 357. At this time, the arm 360 moves with the driven link 357 and after the shaft 350 is rotated one revolution, the tail becomes 360a come into contact with the spring-loaded ram 367, which is now in is in the position shown in dash-dotted lines in FIG. 48 and will cause dcr Lever 360 counterclockwise swings about pin 359 so as to disengage protrusion 361 therefrom Recess in the drive member 356 and to stop the disc 357, since the block 358 prevents lever 360 from moving further about pin 359. At the same Time the hook falls 365th in a recess, as also in the dash-dotted line Lines shown in Figure 4B formed in disc 357 so as to prevent that the disc is spinning in the wrong direction.

As a result of the single revolution of the shaft 350, which is in the just described Manner is generated while the sheet 320 is still, the mechanisms 325 work, 326 and 327 so that a record falls onto the sheet in the following manner. When the shaft starts rotating, it is the bottom record in the stack BR has been separated from this and rests on fingers 329 with the stack supported is by fingers 331 (Figure 4). The rotation of the shaft 350 causes the Cam 337 and 338 are rotated by shafts 339, 343 and 344 and the fingers 329 are withdrawn (Figure 4C) from below the record, which is downwards falls onto sheet 320. Fingers 329 then advance again (Figure 4D) and fingers 331 are withdrawn 80 that stack BR falls down slightly onto fingers 329 that are now carrying it (FIG. 4E). The fingers 331 have now been moved forward, so that they separate the lower record from the rest of the stack (Figure 4F) and the stack is again carried on fingers 331 so that now a duty cycle of the mechanisms 325, 326 and 327 is complete and these themselves are back in their original state, ready for the next operation, which is executed when the arrival of another sheet from the photocell 376 is detected. This final operation of advancing fingers 331 for Carrying the stack is possible because the central part of a record (i.e. the part that does not have sound grooves) is thicker than the remaining part, so that actually already the edges of neighboring records in the stack BR from each other are separated. In Figures 4C to 4F this separation is shown excessively large, since it would not be recognizable if it were drawn to scale.

If the record has fallen on the sheet 320, the latter becomes the latter carried away from the position shown in Figure 4 by conveyors 105 in the direction of arrow A.

Reference is now made to FIGS. 5 to SD. In Figure 5 the sheet can be seen, here with the reference number 100, and it is in the direction of of arrow C by two fingers 104 carried by chain conveyors 105, pushed forward, the chain conveyors being driven by sprockets 106, dio are keyed onto a shaft 107, which is intermittently transmitted by a motor a gear box (not shown) is driven. The arrangement is such chosen5 that during each cycle of the intermittent drive the fingers 104 and thus the sheet 100 will stand still for half a cycle and up for half a cycle Move cycle 0 The shaft 107 is on rotatably mounted at their ends in bearings attached to side frames 108 that are supported on one another opposite ends of a number of transverse frames running along at intervals of the frame 108 are arranged.

Two of these cross frames are shown at 109.

The sheet 100 is supported along each of its side edges, i. of the edges extending in the direction of movement of the sheet by fixed ones Panels 110 carried between the side frames 108 on brackets 111, which latter are attached to some of the outer frames 109. As the sheet continues is pushed forward by the fingers 104, the leading edge 101 of the sheet overflows two rectangular windows 112, one in each of the fixed panels 110. Adjacent each window 112 and disposed on the underside of the panels 110 is a pair of consoles 113, which carry a short, rotatably mounted spindle 114 between them. Approximately in the middle of the length of the spindle 114, a plate 115 is attached, whose one part forms a flap 116, while the other part 117 forms a block 118 to its end. The block is brought into contact with a cam by a spring 119 120 pressed. The two cams 120 are attached to a shaft 121 which is rotatable is mounted in supports 122 attached to an outer frame 109 and is driven is driven by shaft 107 via sprockets 123 and a chain 124. The arrangement is chosen so that the flaps 116 are moved by the cam 120 such that they protrude through the windows 112 and so remove the leading edge 101 of the sheet from the Top side rl n n s A ~ of the plates 110 lift off, as in FIG. 5 shown.

The purpose of lifting the leading edge of the sheet is to prevent this from the leading carrier 125 of a pair of carriers 125, 126 meets, which together form a pocket, which receive the sheet 100, grab and can continuously promote.

The carriers 125 and 126 are at their ends on chain conveyors 127 mounted and extend at right angles to the direction of movement of the sheet between the stationary plates 110. The chain conveyors 127 are of a A pair of sprockets 128 supported on the shaft 107, namely freely rotatable, and driven by another pair of sprockets (not shown). The chain conveyors 105, when they are actually moving, driven at a speed that is twice the speed, with which the chain conveyors 127 are driven, i.e. the medium speed conveyor 105 is the same as that of conveyor 127. So in this way the leading edge 101 of the sheet will meet the supports 125 when the flaps 116 are not would be provided.

The fingers 104 push the sheet further, with the leading part of it slides over the top of the beam 125 until the front surfaces (the surfaces in Touching the sheet 100) the fingers reach a position vertically above of the center of shaft 107 is at what time the sponsors 105 and thus the fingers 104 are stopped, a brush 129 being provided (see Figure 5) to ensure that the sheet stops at this point as well.

The sheet 100 is now in the position shown in Figure 5h is. However, the chain conveyors 127 are still driven so that the carrier 125 now begins to catch up with the leading edge of the sheet. The carrier 125 becomes moves at a speed chosen so that. when he is leading Edge 101 of the sheet runs past, the latter falls off onto a ledge 130 (Fig 5E) onto the carrier with a rib 101a slightly removed from a surface 131 which forms a right angle with bar 130.

The carrier 126 (Figures 5C and 5D) consists of a rod 132 which extends between and is carried at their ends by the chain conveyors 127. The rod 132 'is spanked with end parts 133 which are bent upwards at right angles and each of which carries a rod 134. Halfway down the length of the rod 132 is cut a recess 136 through which one end 137 of a lever 137a extends, which is pivotally mounted at 138 on lugs 139 attached to the Underside of the rod 132 are supported.

The end 137 of the lever 137 protrudes into a slot 140 formed in a rod 141 is formed, which is slidably mounted on the rods 134. The other end 142 of the lever 137a carries a roller 143 which has a fixed cam ~ surface 144 can attack when the carrier 126 the. position shown in Figure 5A achieved, with the role gagen the Cam surface 144 by means of springs 145 is pressed on the rods 134 between the end portions 133 and the rod 141 are arranged. A plate 147 (see Figure 5D) is on the top of the rod 141 attached and has such dimensions that it extends over a surface 146 of the Rod 141 extends out and forms a lip 148, the purpose of which will be described later will.

The arrangement is such that the distance between the surface 131 of the support 125 and the surface 146 of the rod 141 equal to the length of the sheet i.e. the distance between the ribs 1Qla and 102a. However, if the wearer moved beyond the position of Figure 5A, the rod 141 is over a short Distance moved backward relative to the direction of movement of the carrier 126, namely by swinging the lever 137a about its pivot point 138 by the cam 144 will. As the carrier 126 moves further, the surface 146 of the rod 141 engages the blade 100 and, in conjunction with the lip 148, holds the rib 102a within it properly folded position. At the same time, the rod 141 starts the sheet 100 to move in the direction of arrow C (Figure 5).

At this moment the leading end 101 of the sheet is on the ledge 130 of the carrier 125, but as previously mentioned, slightly away from the surface 131. With further movement of the carrier 126, the rod 141 returns to its starting position under the action, of the springs 145 back, controlled by the cam 144, so that zU the time the roller 143 disengages from the cam 144, propelling the sheet forward is, from the rod 141 relative to the 'carrier 125, so that the sheet is compliant seized is between surface 131 of carrier 125 and surface 146 of carrier 126. Das'Blatt is shown grasped in Figure 5B in the manner described above.

Next, the arrangement of the weighing test unit "61 (Figure 2) described in detail, specifically with reference to Figures 6 to 6C. As from Figure 6 complete covers (i.e. containing a record3) are supplied in the direction of arrow D (Figure 6) from pusher, one of which is shown at 126 and which are carried on chain conveyors 127 driven by sprockets 150 which are attached to a shaft 151, which via gears of a drive unit 152 is driven.

Just before the pusher 126 a position above the center of the shaft 151, a pair of further pushers 250 engage, only one of which is shown in FIG 6, and which are carried on chain conveyors 251, the trailing ones Edge of the envelope (viewed in the direction of movement) and accelerate the Shell in the direction of arrow D away from pusher 126. Chain conveyors 251 extend between two pairs of sprockets 252, 253, with the sprockets 252 at a shaft 254 are attached, which is also driven by gears from the drive unit 152 and the sprockets 253 are freely rotatable on a shaft 255. The shafts 151, 254 are driven by the unit 152 so that the linear speed the pusher 250 is greater than the linear speed of the pusher 126.

In Figure 6 is a complete case CS (containing a record) shown as it is supported by the pusher 250 via a horizontal support plate 256 to a reverse and weight check unit 257 is pushed. Unit 257 consists from a carrier wheel 258 which is rotatable and adjustable in twelve stations and consists of a back plate 259 of an annular shape and a plurality of attachments 260 attached to and protruding at right angles from one Surface of the back plate 259. The wheel 258 is arranged vertically with its axis of rotation parallel to the direction of movement of the chain conveyor 251 when looking at FIG 6A, but offset to one side in relation to the conveyors, so that the attachments 260 closest to the conveyors 251 to those arriving on the conveyors The covers protrude. Each of the twelve index stations on the back plate 259 is with two pairs of attachments 260 are provided, which are arranged in radial alignment, but are spaced apart and the essays of each pair are separated by one Distance, which is slightly larger than the thickness of a finished case, so that they are pockets 261, in which a case can be held loosely when the wheel 258 is clockwise (looking at Figure 6A) is incrementally rotated as will be described.

The sleeve CS is pushed into the pocket 261 by the pushers 250, facing the conveyors 251 until the pushers 250 in relation to their Movement directions are tilted back as a result of one provided on each pusher 250 Tail 250a extending from the end of a fixed rail 262.

The rim 258 is attached to a housing 263 which is attached on a large gear 264 which is freely rotatable on a shaft 265 which is rotatable is carried in another housing 266 attached to one end of a support plate 267 is attached. A shaft journal 268, which is also attached to the support plate 267 is, carries a rotatable collar 269, which in turn has a gear 270 at one end carries, which is in engagement with the large gear 264, and at the other end one Plate 271 (Figure 68) with six radial slots, this plate being the driven Forms part of a Naltesian index unit. Another shaft journal 272, rotatable stored in the support plate 267, is continuously driven via a belt and a transmission, shown schematically in broken lines, of the drive unit 152. An arm 273 is attached to one end of the shaft 272, which carries a roller 274 at its outer end and which carries the driving part of the Maltese index unit '. The arrangement is chosen so that with every revolution of the shaft journal 272, the wheel 258 is rotated by 30 ° during a third .der Rotation and over the two other thirds is stationary.

If the Stöassr 250 tilt back, basohrieben as before, and if the case is arranged in a pocket 261 the wheel 258 around rotated one step further and the following casing from conveyor 251 can be in the next pocket 261 can be inserted. When three step movements have been made, after a sleeve has entered one of the pockets, the pocket comes to rest, in such a way that the sheath CS is in a vertical position, as shown by the reference numeral 255a is indicated in Figure 6A. While the case was carried around by the wheel 258 will carry it on its inner edge, i.e. the edge that is the axis of rotation of the Wheel 258 is directed towards, two solid surfaces 275. Each of these surfaces 275 has one stage 276 (FIG. 6C), at such a point that when the Sheath reached the position 255a, it from the.

Stage 276 expires and falls onto a platform 277 that is part of a weighing device 278 forms. The latter consists of a frame 279 on a base plate 280 is mounted in the form of a hollow box that is supported is on a fixed plate 281, which in turn is attached to the other end (i.e., at the end remote from the support plate 267) of the housing 266. The frame ' 279 carries a pivot pin 282 on which a handle 283 is freely mounted. The lever 283 is counterclockwise (when viewing FIG. 6C) by means of one Spring 284 pressed against an adjustable stop 285. Also freely movable on pivot pin 282 is another lever 286, one end of which is the platform 277 carries; the platform 277 is arranged at right angles to the lever 286 and to one side of its center line, as that the weight of a garbage that is on the Platform 277 acts, a pivoting movement of the Mebele 286 around the pin 282 causes. The other end of the lever 286 carries a thin plate 28? Which perforates at 288 with the plate 287 arranged to swing about the pivot point 282 can be between a light source and a pair of totoeQectric cells that work together a test device 289 form. The lever 286 is turned counterclockwise the pivot point 282 is pressed by means of a spring 290 which is positioned between the levers 2B3, 286 is mounted.

The arrangement is such that when the shell CS is on the platform 277 in the manner described, lever 266 and plate 287 fall clockwise swing about pivot pin 282 and come to rest in a position that determines is determined by the weight of the envelope with its contents. The perforations 288 are in such Arrangement on the plate 287 provided that, according to the position of the lever 286 and the plate 287, when they have come to rest, the photoelectric Cells are illuminated and generate a signal that indicates one of three possible states Indicates the weight of the shell CS. These states are 1lightly, "correct weight", "heavy", and are indicated by one, two or no illuminated photoelectric Cell and correspond to the cases in which a light is none, one or more than contains a record.

The properties of the springs 284, 290 are chosen so that when the Case is of the correct weight, lever 286 to Calm comes when he is engaging the lever 283 without moving the latter significantly. If the sheath is light, the movement of lever 286 will be much less, than with a case of real weight, while when the case is heavy, itself the lever 286 will move significantly past the point at which the lever 283 is attacked, in spite of the requirement outside of the spring 290, the spring is also attacked 284 to clamp.

If the case CS only contains one record and a real one Weight "signal is generated by the tester 289 and after the wheel 258 is rotated three more steps, the shell CS is again in the horizontal (i.e. rotated 1800 from the position in which it entered a pocket 261 had been). While the wheel 258 is in this position, the envelope becomes CS ejected from the pocket 261 by a reciprocating pusher 291, in a direction transverse to the longitudinal axis of the attachments 260, and indicated by the Arrow E in Figure 6A to the leading end of the casing (viewed in the direction of the Arrow E) is taken between a driven belt conveyor 292 and a Pressure rollers 293 which work together to guide the casing CS to facilities which wrap the envelope in an outer envelope.

The pusher 291 is supported by a pair of rods 294 (from only one of which is visible in the drawings), each movable to and fro in a pair of blocks 295 are mounted (only one pair visible in the drawings) attached to the base plate 280. A Lever 296 is connected at one end to pusher 291 and at the other end to a further lever 297, which is at the right end (when observing FIG. 6) Shaft 265 is attached.

At the other end of the shaft 265, an arm 298 is attached which is in connection stands with a handlebar 299, which in turn is connected to an operating lever 300 near one end of it. The actuating lever 300 is pivotably mounted on the support plate 267 at 301. The end of the operating lever 300 that extends from the handlebar 299 is removed, carries a roller 302 which is engaged with a cam 303, which is attached to a further shaft journal 272, with a spring 304 acting as the roller keeps in touch with it. When the cam is rotated continuously, it moves the pusher 291 back and forth in such temporal coordination with the carrier wheel 258, that the pusher 291 is actuated while the carrier wheel 258 is stationary, A with a hooked lever 305 pivotally supported on the support plate 267 is connected to the output shaft of a rotary solenoid 307 via link 306. Another hooked lever 308 is attached to the actuation lever 300.

The arrangement is such that the solenoid 307 is energized upon reception a "correct weight" signal from tester 289 which causes the hooked lever 305-die Occupies the position in Figure 68 is shown in which case the roller 302 is in contact with the cam 303 remains.

The electrical circuit of the device is such that when the solenoid once aroused, it remains in this state until it is de-energized by either an 11light'9 or "hard" signal from the test device 289 caused by a case containing either no or more than one record.

When the solenoid 307 is de-energized, as described above, it is effective the roller 302 to the highest part of the cam 303, so that the further with hook provided lever 308 is in such a position that the hooked Lever 305 can be brought into engagement with the hook on lever 308 by a Spring 309. This prevents the roller 302 from the cam 303 during its next Rotation follows so that the envelope, either no or more than one record contains, is not ejected from the pocket 261 of the pusher 291. It has already been mentions that the wheel 258 is rotated three more steps from the weighing position into the position of the pusher 291 and the signal from the testing device 289 is generated, is stored in any way (expediently with a three-stage change register) during this period.

Cases that are not ejected by the pusher 291 are removed from the wheel 258 are carried forward by three more steps and during this time they are in the pockets 261 held by a guide 310 until they are back in a vertical position (i.e. around 1800 away from position 255a). When the wheel comes to rest in this position, the covers run off the end of the Guide 310 and drop vertically downward against a wall 311 on a conveyor 312, which forms a reject container from which envelopes can be collected when required can.

The mechanism for inserting the records into the pouch is shown in Figures 7 through 7E. As can be seen from these figures, in this Mechanism a paper bag 160 is fed, in the direction of arrow t (Figure 7B) by means of a finger 161 mounted on a chain conveyor 162 which carried by a sprocket 162a that is attached to and continuous is driven by a shaft 162b, to a record inserter 163 out. At the same time, a record 164 is fed in the direction of the arrow G (Figure 7B) to the device 163 by means of a pusher 165, which is on another Chain conveyor 166 is mounted, which is carried by a sprocket 166a, the is attached to and continuously driven by a shaft 166b. The waves 162b and 166b are both driven by gears (not shown) from an input shaft 208 (Figure 7) driven, which in turn is driven by a continuous Drive unit 209. The conveyors 162, 166 are arranged so that the bag and the record3 is transported to facility 163 in the same plane, but at right angles to one another, as can be seen from FIG.

The bag 160 is oriented so that its open edge is parallel to its direction of movement and to the record kn iat so that the latter can be inserted into the bag in a manner to be described below Device 163 consists of a box-like construction, open at the top and bottom, with a front wall 167, a rear wall 168 and two side walls 169, 170. The Side wall 169 is so gesteltet that it has the right end (when viewing Figure 7) a housing 171 can receive and carry along its top surface the bag 160 is fed by the finger 161 and the front wall 167 is shaped so that that they are the right end (when viewing Figure 7A) of a pair of side frames 172 can accommodate and carry on which guides 173 are mounted9 the record 164 support and guide 9 while the latter is pushed forward by the ram 165, The Guides 173 are arranged parallel to one another and so far apart from one another that that the record 164 is V-shaped at diametrically opposite points Grooves 174 (see Figure 7) is carried 9 along the mutually directed Surfaces of the guides 173 are provided.

The pusher 165 is provided with two upwardly extending projections 165a, which are also provided with V-shaped grooves, as shown in FIG. 7A ersehen0 The record is supported at four points around its circumference and this ensures that it cannot tip over9 while it is being moved. the Guides 173 extend in the direction of arrow G to a position which is at the same height as the front wall 167.

The finger 161 conveys the bag 160 to the leading edge of the same is gripped between a driven roller 175 and another roller 175a, the resilient genen the roller 175 is pressed. The roller 175 is on a shaft 176 mounted, supported in bearings on the front and rear walls 167 and 167 respectively. 168 are mounted, the rollers 175 and 175a are close to the front wall 167 (see 7B) so that they grip the bag adjacent to its open edge. At the same time that rollers 175, 175a grip the open edge of the bag, the edge opposite this edge is gripped from above by suction and this induced draft rests against a suction chamber 178 along the underside of which continuous perforated belt 179 running between a pair of pulleys 180, 181 is worn. The pulley 180 is attached to the shaft 176 and the Roller 181 is mounted on a further shaft 182 which is between the rear wall 168 and a partition 183 (Figure 78).

Mounted on shaft journals 184, 185 are two suction wheels 186, 187, arranged vertically one above the other, with the wheel 186 arranged above the plane along which the bag 160 is fed and the wheel 187 below it level is arranged (see Figure 7) induced draft from a suction source, not shown Her is fed to the wheels 186, 187 through two chambers 188.

The wheels 186, 187 are eccentric on their respective shafts 184, 185 arranged symmetrically opposite one another, so that during each revolution of the wheels move their circumferential surfaces, initially during half a revolution away from each other and then towards each other during the second half turn. the Pulley 175, air-permeable belt 179, and wheels 186, 187 all become intermittent driven by gears from an input shaft 210 (Figure 7), which in turn intermittently is driven by a drive unit 211 o With further movement of the bag in the direction of arrow F (Figure 78) runs the leading edge of the same between the circumferences of the suction wheels 186 and 157 through9 each other at that moment almost touching it (as shown in Figure 7), causing suction to hit the two surfaces of the bag acts 9 around the top and bottom surfaces of the bag against the wheels 186 or 187, if the bag is moved further9 the capes move the boiden wheels and thereby the bags face away from each other until after one half a turn the wheels 186, 187 keep the opening of the bag open9 and sufficiently far to allow the insertion of the record 164.

The record 164 is conveyed by the pusher 165 into a position so that another pusher 189 with a V-shaped groove in its leading surface, which runs at a higher speed than the pusher 165, the record attacks and accelerates it away from the ram 165. The pusher 189 is worn of two chain conveyors 190 and the leading surface of the pusher 189 is arranged so that it engages the record between the projections 165a of the pusher 165 (Figure 7). The chain conveyors 190 are supported by two pairs of sprockets 191, 192 supported, the sprockets 191 being freely rotatably supported on a shaft 193 between consoles 194, and the sprockets 192 are attached to a driven one Shaft 195 carried between two fixed walls 194a that are between the walls 167, 168 extend. The shaft 195 is driven by gears (not shown) from the continuously driven input shaft 208. The pusher 189 is pivotably mounted on the chains 190 and is turned clockwise (at Viewing Figure 7A) pressed by a torsion spring mounted on its pivot joint is stored with the pusher in the correct orientation for engaging the record 164 is held by two rails 196, which extend up to a point directly extend behind the suction wheels 186, 187 (viewed in the direction of movement of the ram 189).

FIG. 7C shows how the plate 164 is pushed by the pusher 189 and also the bag 160, the. just got in touch with the Suction wheels 186, 187 is reached, the closed edge of the bag from the perforated Strap 179 is worn.

Figure 7D shows how the bag is opened as described above, and the record is pushed into the bag by the pusher 189. If the Record is completely inside the bag, i.e. when the edge the record is in contact with the sealed edge of the bag, which is the opposed to the open edge, the pusher also pushes the bag that is over the perforated belt 179 slips while it is still being carried by this. The pusher 189 pushes the record and with it the bag, until the now leading one Edge of the bag (viewed in the direction of its movement, which is now through the Direction indicated by arrow H) touches a rubber pad 197 which is on the Rear wall 168 is mounted, this position being shown in Figure 7E. if When the bag touches the cushion 197, the pusher 189 rolls off the rail 19G and pans clockwise away from the record, as in dash-dotted lines Lines shown in Figure 7E. At this moment the suction is also perforated The belt is switched off and the record in the bag falls downwards like shown by arrows 3 in Figure 7E. The record in its bag catches the eye the top surface of a pair of support rods 198, 199, each on pivot pins 200, 201 are attached, which are carried in brackets 202 on the inner surfaces the side walls 1699 170 are attached. the Rods 198, 199 are movable into the position shown in dash-dotted lines in Figure 7, this movement being controlled by a pneumatic cylinder 204, whose Piston is attached to one end of a lever 205, the other end to the pivot pin 201 of the rod 199 is attached. Another lever 206 is at one end with the The pivot pin 200 of the rod 198 is connected and the two levers 205, 206 are Connected via / handlebars 207 so that the rods 198, 199 are common to the cylinder 204 be moved.

When moved in the manner just described, it falls into a bag located record further in the direction of arrows z in Figure 7E to the Top of a stack of pouched vinyl records.

Finally, the details of the parts of the machine have to be added Describe through which the records run before they're put into bags as just described.

This is done first with the aid of FIGS. 8 to 8F, which are a part the machine through which the records pass first.

As can be seen first from Figure 8, there are two stacks of records 390,390a shown, each arranged below suction feed units 391, 391a taking consecutive records from the top of the stacks can. The stack 590 is shown after some records have already been removed from it the unit 391 has been removed and when the last record has been removed, will the Unit 391a actuates to begin recording the records from the top of the stack 390a.

While records are being removed from stack 390a, a another stack placed below the unit 391, which begins to operate after the stack 390a is exhausted, etc. Scarf removed from the stacks 390, 390a plates are carried by the associated conveyor units between a pair of horizontal Guides 392 placed, only one of which is visible in Figure 8 and along them the records are pushed in the direction of arrow K, by finger 393, carried on chain conveyors 394. Upon reaching the right end of the Guides 392 (when viewing Figure 8) drop the records on top of a small pile 395, which serves as buffer storage, and are individually removed from the Bottom of stack 395 removed by a mechanism not shown, which does not form part of the present invention, the stacks 390, 390a are placed on pallets 396, which are movable, over a flat horizontal table 397, into the positions shown. Each pallet has a vertical central column 398, which extends through the center holes of the records, as well as three Provide holes that are symmetrical around the center and within an area which corresponds to the label area of the record (i.e. the part in the center the record, where no visual grooves are provided).

When a pallet is arranged below one of the feed units 391, 391a the holes in it are aligned so that they line up with three more holes lie in a line provided in the table 397 so that three rods 399 (Figure 8) can protrude through the aligned holes to the stack of records raise, as will be described later, in a position adjacent to the associated Suction feed unit.

As the mechanisms for removing records from the stacks 390, 390a are identical, only the mechanism for removing Records from stack 390 described in detail.

As seen in Figures 8A, 8B, and 8C, the rods are 399 attached at their lower ends (Figure 88) to a triangular platform 400, at each corner of which a bearing 401 is attached. These bearings are slidable on Guide rods 402 extending vertically between the underside of the table 397 and a base 403 extend. The platform is raised and lowered between the rods 402 by means of a chain 404, which runs around sprockets 405, which on shaft stubs 406, the lower of which is driven by a reversible motor 407 via another chain 408. Attached to one of the guide rods 402, close a position close to the base 403, a microswitch 409, and in one place Another microswitch 410 is located near the table 397.

At work the machine is a pallet-396, which is a pile of records carries9 moved into the position shown in Figure 88, where theyfigegen a stop 411 is placed.

At this stage the platform 400 is stationary and at the bottom their path of movement so that the upper ends of the rods 399 are below the Table 397 are located. In this position, the holes in pallet 396 are aligned with the holes in the table 397. After the pallet is against the. Stop 411 placed a start button (not shown) is pressed in order to start the motor 407 to let that drives the chain 404 in such a direction that 'the platform begins to be picked up. This causes the rods 399 through the aligned Pass holes in table 397 and pallet 396 to engage with the pile of records that look out the pallet is carried and to lift it. This movement continues until a microswitch 412 is opened which causes that the motor 407 and thus the platform 400 stop. The switch 412 is operated by one end 413 of a lever freely mounted on pivot pin 414, which is worn in a manner to be described later.

The other end of the lever is designed as a finger 415 that on the top of the stack of records. When records from the top of the stack are removed, the height of the stack and fingers 415 decrease so oscillates counterclockwise on shaft 414 until the end 413 of the finger 415 closes the microswitch 412, the causes the engine 407 starts up again and drives the chain so that the platform is raised. The level of the top of the stack is kept at an almost constant height. As the stack moves up toward finger 415, it is guided sideways by two pairs of posts 416, 416a (Figure 8A) so that the sides of the stack be held approximately vertically.

The suction unit 391 is shown in detail in Figure 8C and consists from a housing 417 which carries three suction pads 418 which are equidistant are arranged around a flange 419 provided on the underside of the housing is. The cushions 418 are connected by tubes 424 carried in the housing 417 with a suction line 425, which in turn is connected to a suction source (not shown) connected is. Another tube 426, also carried in the housing 417, is with a compressed air source (not shown) connected.

A socket 420 is provided with a flange 421 on the underside of the flange 419 is attached and extends into a vertical bore 422, which is formed in the center of the housing 417. The socket 420 has a hole 427 which is aligned with the tube 426 and has a longitudinal slot 428 in its inner surface between the hole 427 and the top of the socket. Along the center of the bushing 420 is a pusher 423 movable downwards, which is attached to his the upper end is provided with a flange which engages the upper End of the bushing 420 and prevents the pusher 423 from falling out of the bushing 420.

Dr Stösser 423 has a circumferential recess 4299 which during the decrease The top record from the stack is aligned with the hole 427 in the socket 420. The pusher extends below the suction pad 418 and is on its lower end formed into a short cylindrical nose 430, with a diameter which is smaller than the diameter of the center hole in a record9 and a slot 431 is the recess 429 provided in its end face.

communicates with the slot 431 through a hole 432.

The unit 391 is mounted9 so that it can be moved vertically to the Top of the stack 390 back and forth as they successively record records from it0 For this purpose a rod 433 is provided (FIG. 8B) which extends vertically upward from the top of the housing 417, through a fixed bearing block 434 through which the rod 433 can slide0 The block 434 is worn between cross links 4359 which are attached at their ends Side frame 436 of the device0 The blocks 434 are arranged9 so that the unit 391 moves along a vertical path9 offset slightly to the left (when viewing Figure 8B) versus the vertical center line of the stack 390o The unit 391 is raised and lowered by means of a cam 4379 of the is attached to one Camshaft 438, which rotates as if by the arrow shown in Figure BE, and on which a roller 439 runs, which is from a Arm 440 is carried, which is pivotably mounted at one end on an Ilellenzapfen 441 and at the other end on top of rod 433. Roller 439 is held in contact with the cam 437 by means of a spring 442.

Before the top record of the stack can be removed, it must be moved to the left (when looking at Figure 8B) so that its center hole is vertically aligned with the nose 430 of the unit 391. To this end, will finger 415, previously described as a height checker for stack 390, moved by means of a cam 443, which is also attached to the camshaft 438 is and on which a roller 444 runs, which is carried by an arm of a toggle lever 445, the pivotally mounted at 446 is carried. The other arm of the lever 445 carries den and is freely connected to pivot pin 414. To allow sideways movement of the The two posts 416a (Fig 8A) designed on their surfaces engaging the stack near their upper ends so as shown at 447 in FIG. One end of the finger 415 that the Attacks the record is designed as shown in Figures 8D to 8F is. The surface 415a is of such a depth that it engages the Edge of only the top record, with face 415b being the top surface the top record attacks, and area 415c is like this formed9 that it attacks the edge of the uppermost record9 after the latter moved and the finger was withdrawn so that the finger did not move can move to move the next record9 to the top record This situation is shown in Figure BE, in the dash-dotted line Lines indicate a record9 that has not yet been lifted off.

The removal of a record from the top of the stack 390 is performed now described. When the parts are arranged as shown in Figure 8a is, the switch 412 is open and the motor 407 is stopped0 The finger 415 rests on the top record 0 The finger moves forward (to the left in Figure BB) and pushes the record forward> until it reaches the shaped part 447 the post 416a engages9 and in this position is the center hole of the Record vertically below the nose 391 430. The unit / is lowered and the nose 430 goes into the center hole of the uppermost record and rests on the the next lower record, the center hole of which is still in the vertical one Center line of the stack 390 is located (Figure 8D) o The finger 415 is then moved back, so that it releases the top record and lies on the next bottom 9 ready to move this to the left. As long as the housing 417 is still moving downwards, the pusher 423 will move up relatively to socket 420, to align recess 429 with hole 427 in sleeve 420; as well as with the further line 426 in the housing 417. As a result, the flange, which is provided at the top of the pusher 423, moved away from the top the socket 420 which connects the further tube 426 with the space between the top of the pusher 423 and the end of the hole 422 in the housing 417, via the hole 427 and the slot 428. The housing 417 continues to move downward until the pads 418 attack the label area of the record surface and then suction is applied to the pads 418 and compressed air through line 426. The compressed air enters Recess 429 through the hole 432 and further out through the slot 431 in the End of the nose 430, thus helping to move the top record from the next Lower pressurized air also flows out of hole 427 along the slot 428 into the socket 420 and into the space above the top of the pusher 423. The Compressed air acts on the top of the pusher 423 and on the closed end of the hole 422 in the housing 417. Since the pusher cannot move down when the nose 430 is in contact with the stack 390, the housing 417 and thus the cushions 418 pushed up and the top record lifted and off the stack separated as a result of the induced draft acting on the cushions. When the record disconnected is, the compressed air in the line 426 is turned off and the pusher 423 reverses back to the position shown in FIG. The unit 391 continues raised from cam 437 until the record is arranged to be gripped can through two gates 448, 448a (Figures 8A, 8B) at two diametrically opposite Places which are designed as movable parts of the guides 392 (FIG. 8E) The gates 448, 448a are attached to one end of levers 449 and 449a, respectively the lever 449 is freely supported on a shaft journal 441 and the lever 449a freely is carried on another shaft journal 450. The other ends of the lever 4499 449a are pivotally connected at 451. The lever 449 carries a roller 4529 which rides on a cam 453 attached to camshaft 438.

When the record raised on the cushions 418 reaches the position has9 shown in Figure 8E9 the gates 449, 448a are out of alignment moved with the guides 392 as shown in that drawing. The unit 391 is now stopped on its way up while the gates towards the record are moved 9 by means of a cam 453 until they grip the record and at this point the suction is turned off by the pads 418 and the unit 391 moves back up to the nose 430 out of engagement with the center hole to bring the record0 The record is then attacked by fingers 392, which push the record in the direction of arrow K (Figure 8) and they hit the Hand in the top of the small pile 395.

Enclosed in the record case are a number of metal support disks (not shown) 9 which have the same dimensions as a record 9 but not on the Stack 395 to be delivered. The metal disks are from the stack when they reach the top in the same way as a Record carried away, but when pushed along rails 392 from finger 393, its presence is indicated by a magnetic or capacitive one Test device 454 (Figure BA) found, which actuates a solenoid 455 to a another pair of gates 456 in guides 392 corresponding to gates 448, 448a, to cause it to be moved out of the guides 392 so that the metal plates fall into a collection box 456a (Figure 8).

The camshaft 438 is driven by a further shaft 457 via a single-turn clutch 458, which is activated when a solenoid 459 is actuated. The wave 457 is driven by a drive shaft 460 through a chain 461 that is continuous is driven by a drive unit 462 (Figure 8A). The clutch 458 is designed and works in exactly the same way as clutch 351- and that Solenoid 372 shown in Figures 4A, 4B.

When the last record is removed from stack 390, the Switch 410 from the platform'400 is closed and this causes the motor 407 starts up and moves the platform and thus the rods 399 downwards until the Platform to stop switch 409 closes to operate motor 407 /. The poles 399 are now withdrawn under table 397 and the empty one palette 396 can be replaced by a pallet with another stack of records.

The closing of the switch 410, just mentioned, is effected also that records are now further fed from stack 390a by the unit 391a, in the same way as just now with regard to the stack 390 and the unit 391 described.

When the last record in the stack 390a is received from the unit 391a is fed, records are fed again from the unit 391 and the Change occurs after a short time delay, leaving the last record can be pushed into position from stack 390a along rails 392, which does not interfere with the operation of the unit 391.

Records are individually removed from the stack 395 in order to be checked before proceeding (if they prove to be satisfactory when tested have proven), in order to then be introduced into bags in the manner described above. The mechanism by which the records are presented to the testing facilities will be described next with reference to Figures 9 to 9D. In This mechanism carries the records around along a path that essentially the shape of a something has an incomplete figure eight. To accomplish this, the mechanism has two rotatable heads 500, 501. Of the Head 500 has four record bearing members 502 and head 501 has four records supporting members 503. The heads 500, 501 are attached to shafts 504, 505, the are driven intermittently in 90 ° steps by means of a drive unit 506 (see Figure 9B). The members 502 on the head 500 are arranged to be support a record above each record-bearing member while the corresponding links 503 are arranged on the head 501 so that they are a Support the record below the record-bearing members. The purpose of this The difference is that it allows the top surface of vinyl records is checked while moving from the record-bearing members 502 of the head 500 are worn and the lower surface of the vinyl records while they are from the record carrying members 503 of the head 501 are carried.

On the head 500, each record-carrying member 502 has one upward disc 507 carried on a shaft 508 which is rotatably supported by and can be pushed in a bearing 509 and with a central projection 510 is provided, is in the central hole of a located thereon Record can intervene. The central projection has the shape of two hook-shaped ones Spreadable catch links 511, which can be introduced through the MAtisllach one Record and then spread it, as shown in Figure 9D, to make a securely holding the record on the record holding member in properly to allow centered position.

The record-carrying members 503 of the head 501 must have a Hold the record from above so that its lower surface can be checked and each link has three downwardly directed suction pads 512 arranged so as to that they are symmetrical around the center hole of a record carried by it lie.

When a record-carrying member 502 of the head 500 falls under the Position 22 (Figure 1) comes up, a record falls on it. As mentioned above, there is a small stack of records below position 22 and it is the lowest record of this stack that falls onto link 502, where the mechanism for placing the records is the same as that for the stack of located in bags.

Records is assigned, as already explained with reference to FIGS until 4F has been described. When the record is on link 502, the head rotates 500 by 900 counterclockwise (when looking at Figure 9) and another link 502 is thus placed in position, the next following one Record record.

During this 90 ° rotation of the head 500, a wheel 513 engages, the attached to the shaft 508, a stationary rail 514 on and rolls along it, causing shaft 508 and disk 507 to move Rotate on its own axis so that the record is on disk 507 upon completion the 90 ° movement rotates. When the head 500 is in this position the rotation is maintained by engagement between the wheel 513 and a constantly rotating drive wheel 515. While the next following record is picked up by the head 500, the first recorded disc is checked and if the next following record is correctly recorded on the corresponding one Link 502, then the head 500 leads a further 90 ° movement counterclockwise off and the first-mentioned record is moved to another position, on which it will be checked further and if so, then another record on one third link 502 is received, brings about a subsequent 90 ° rotation of the head 500 the first-mentioned record to a point where the limb 502 of the head 500, which carries the record, is located below a link 503 of the head 501 is located. At this stage, the first-mentioned record is turned upside down 501 transfer, whereby the limb 503 of the head 501 is lowered somewhat and thus absorbent pads 512 of the member 503 of the head 501 brings into contact with the record, whereupon Induced draft is applied to this pillow.

Dietes-Abasnken is mechanically effected by a cam 516, the a corresponding lifting of the link 503 allows before it leaves the position 25, the link 503 of carried by a tubular spindle, which is vertically displaceable and under the upward pressure of a spring 518 stands so that a cam gripper 519 at its upper end against a nockon 516 is held .. An additional increase is given relative to the suction pad the remaining part of limb 505 by placing each suction pad on a small piston 520 is movable in a cylinder 521 which forms part of the link 503, wherein Induced draft is applied to the cushion through the cylinder and a hollow piston rod via the suction line 522 from a continuously operating pump 523. If this Arrangement once suction: train is applied and a record attacks the pillow, a pressure drop in cylinder 521 raises piston 520 and thus the cushion relatively to the cylinder and the remainder of the limb 503. The pumps 523 of all limbs 503 become driven by a sun gear 524 which meshes with individual drive gears 525 of the various pumps.

When this transmission is achieved9 the head 501 rotates 900 clockwise. At the point9 to which the record is then brought9 checked its lower surface and when the head 501 makes another 90O rotation9 the record is brought to a position5 at which it can be subscribed by the induced draft supply to the cushions of the member 503 is switched off and the record then something falls down onto a conveyor device 526 (FIGS. 9, 9C), the channels 527 forms to grip the 'edges of the record outside whose Sound groove area and pusher 527a push the record to a point where the inner bags are located to hold the record, adjacent the position 6 (Figure 2), at which the records in their bags on the back roasters be filed.

Induced draft is applied to the pads of each link 703 in the correct position switched off by venting the associated pipe 522 with atmospheric pressure through valve 528 which at this time is aligned with a working ram 529 of a solenoid 530 (Figure 9C). The falling of the record onto the conveyor 526 is decreased by lowering member 503, with another cam 531 a cam gripper 519 is actuated for this purpose.

However, each record is only placed on the conveyor 526, if during the test processes on the same, while they are from the heads 500, 501 is worn, no mistake was made, the rejection of the record justifies. However, if such a fault is found, the induced draft is maintained (i.e., the pusher 529 is held up) on the cushions of the limbs 503 of the head 501 carrying each record when the latter is brought above conveyor 526 is,. and this suction is maintained until the head 501 another Has made a 900 turn clockwise. Only then is the induced draft switched off by another solenoid (not shown) to the solenoid 530 corresponds to y, and the record falls off the head 501 into one not shown Container for faulty records.

While each record is on its head 500, it becomes on two. Brought to places where it will be examined while when it is on the head 501 is located, it is only brought to a test site. Becomes expedient at the first test point on head 501, a test for evenness and concentricity of the record and here the record is also cleaned in preparation for testing their upper and lower surfaces, these tests being carried out while the record is spinning.

At the second test location on head 500, the top surface becomes the Record tested and a corresponding test of the lower surface of the record is executed while the latter is at the only test point on head 501, these tests being carried out while the record is stationary, however, an appropriate scan of their surface is provided by the testing facilities causes.

The invention is not limited to that shown and described Embodiment and can e.g. also be useful for the packaging of other items been designed.
