Description

WAREHOUSE FOR LAMINARY PRODUCTS.

DESCRIPTION

The invention relates to a warehouse for laminar products, especially for laminar products in plate, particularly suitable to be used to arrange such laminar products in plate in a position of easy grip for manual or mechanical handling.

The warehouse of the invention can be used to store laminar sheet products of any kind such as plastic sheets, wooden panels, metal sheets and similar semi-finished sheet products.

Preferably, the warehouse of the invention is used in sheet glass processing companies where it is used to store the glass sheets which must be picked up and loaded, for example, onto cutting surfaces.

It is known that the warehouses for the storage of sheet laminar products, particularly for glass sheets, comprise a plurality of frames aligned one after the other, each of which is inclined to receive one or more sheets in support which are arranged facing and superimposed on each other.

The plane defined by each frame is inclined by an angle slightly higher than 90 ° with respect to the horizontal plane in order to ensure the slabs that are placed on it, facing one another, a safe and stable support guaranteed by their own weight. .

Generally, in a warehouse there are a head frame and a tail frame both fixed, between which a plurality of intermediate frames are included which are provided with trolleys arranged in support of a support structure generally arranged on the ground. Each intermediate carriage is mobile as it is connected to suitable motorization means which allow it to be moved along the support structure and therefore with respect to the other frames.

In particular, the distance between the head and tail frames is greater than the overall distance of the intermediate frames when they are arranged close to each other and this allows, by suitably moving one or more intermediate frames by means of the motorization means, to spacing any two of the frames adjacent to each other so as to open an access corridor to the sheet gripping means.

Therefore, when the user wants to extract one or more of the slabs stored in the warehouse, he moves the frames appropriately in order to access the frame or frames in which the slabs he is interested in are present or are present.

However, the warehouses of the known type described have some recognized drawbacks and limitations.

One of these drawbacks concerns the constructive aspect of the known warehouses and is constituted by the fact that they contain a plurality of motorization units which are used for hooking and unhooking the individual frames and for moving them.

It is understood that this entails a significant constructive complexity of the warehouses as well as an equally significant construction cost.

Patent documents US5505574 A, EP1593615 A1, EP0749916 A2, US2002 / 005332 A1 and DE4428897 A1 are known which describe different executions of warehouses for laminar products.

These warehouses feature expensive construction solutions which also require frequent maintenance and adjustment interventions. Another drawback concerns the operational aspect of the known warehouses and is constituted by the fact that their use is rather complex since when you want to open a corridor between two adjacent frames, it is first necessary to recompose all the frames by hooking them together. to the other, then intervene to release the frame in correspondence with which you intend to open the corridor and then act on the movement units to move the frames and open the corridor in the position of interest.

Patent document US6510950 B1 is also known which has the limitation of not allowing the hooking and movement of single frames, at the user's choice.

The present invention intends to overcome all the drawbacks and limitations complained of.

In particular, it is a first object to provide a warehouse for sheet laminar products which is simpler to construct than equivalent warehouses of a known type.

Another object is that the warehouse of the invention has a simpler operation with respect to known types of warehouses.

Last but not least, the purpose of the warehouse of the invention is provided with locking means suitable for guaranteeing the stability of the frames in all the operating positions in which they are arranged.

The listed aims are achieved by a warehouse for laminar products, particularly for laminar products in plate, the characteristics of which are described in the main claim to which reference is made for descriptive simplicity.

Further characteristics of the warehouse of the invention are described in the dependent claims.

The embodiment of the invention which is described below provides for a plurality of frames each associated with a displacement carriage and comprised between a head frame and a tail frame which are instead fixed with respect to a support structure on which the trolleys.

A single movement group comprising a sorting unit for the selective coupling of any one of the trolleys and motorization means, cooperating with the sorting unit, allows to move the hooked trolley to move the respective frame with respect to the frame adjacent to it .

Locking means are provided for removably fastening each carriage to the carriage adjacent to it when these are arranged one next to the other.

Advantageously, by limiting the number of motorization units and therefore also of the elements for moving the frames, the warehouse of the invention also has a more reliable operation than equivalent warehouses of known type.

In a further advantageous way, as will be better highlighted in the description, the warehouse of the invention is more easily manageable than equivalent known warehouses and allows shorter intervention times with the advantage of being able to carry out a greater number of movements at the same time.

The aforementioned purposes and advantages will be better highlighted during the description of a preferred embodiment of the warehouse of the invention which is given as an indication but not of limitation with reference to the attached drawing tables in which:

The warehouse for laminar products object of the invention is represented in an axonometric view in fig. 1 and in the side views of figs. 2 and 3 where it is indicated as a whole with 1.

It can be observed that it comprises a plurality of frames indicated as a whole with 2 and aligned one after the other, which are arranged inclined to accommodate one or more laminar products L overlapping and facing one another in support.

It can be observed in particular that the frames 2 comprise a head frame 2t and a tail frame 2c both fixed, between which a plurality of intermediate frames 2i are included, arranged one after the other and associated with respective carriages 3.

It is also noted the presence of a support structure 4 on which the carriages 3 with associated intermediate frames 2i insist, which allows them to be moved in a direction substantially parallel to the plane a defined by the support structure 4 itself.

The head 2t and tail 2c frames are fixed to the support structure 4 but in a different embodiment they can also be independent from the support structure 4 and be, for example, fixed to the ground.

It is however evident that in a different embodiment all the frames 2 that make up the warehouse 1 can be provided with trolleys 3 and therefore all be movable on the support structure 4 on which they stand.

It is also observed that each of the frames 2 has an L-shaped profile in which the side of greater length 2a forms an angle γ of greater amplitude than a right angle with the substantially horizontal plane Î ± defined by the support structure 4.

In this way, as can be seen in fig. 2, the longer side 2a defines a plane β slightly inclined with respect to the vertical direction, supporting the laminar elements in the plate L which lean against it one against the other, spontaneously due to the weight of the plates.

It is also noted with particular reference to figures 6 to 14 the presence of a movement unit, indicated as a whole with 5, for moving the trolleys 3 along the support structure 4.

According to the invention, the handling unit 5 comprises a sorting unit 6 for selecting and hooking up any one of the trolleys 3 and motorization means 7 cooperating with the sorting unit 6, suitable for moving the hooked trolley to move the frame associated with it relative to the adjacent frame.

As far as the sorting unit 6 is concerned, it can be observed that it comprises a first motorization unit 8, equipped with an encoder not shown in the drawings and connected to a control unit, also not shown, which is mechanically connected by means of a mechanical joint, indicated as a whole with 9, to means for hooking the intermediate frames 2i, generally indicated with 10.

Said coupling means 10 comprise a tubular element 11 mechanically connected to the first motorization unit 8 by means of the mechanical joint 9, which is externally provided with a plurality of sleeves 12, each of which has a pair of projecting elements 13 to hook corresponding elements stop 14 present in the intermediate frames 2i.

The projecting elements 13, in particular, are spaced apart and aligned along the axial direction of the sleeve 12 while the abutment elements 14 consist of any element integral with each intermediate frame 2i, having a thickness less than the distance between the projecting elements 13 of each sleeve 12 in order to be included among these when the sorting unit 6, on command of the operator, chooses which of the trolleys 3 to move. In the case described, each abutment element 14 consists of a flat bar belonging to the respective intermediate frame 2i.

As regards the mechanical joint 9, it comprises a splined shaft 15 connected to the first motorization unit 8 and slidingly coupled into a splined seat 16 made in the tubular element 11.

As far as the motorization means 7 is concerned, they comprise a second motorization unit 17 which, as can be seen, is connected to a threaded shaft 18 coupled with a nut screw 19 made internally to the tubular element 11, on the opposite side where in the element tubular 11 the grooved seat 16 is made. Each motorization unit 8, 17, as can be seen, comprises an electric motor 8a, 17a equipped with a speed reducer 8b, 17b. However, it is clear that each motorization unit, instead of comprising an electric motor with reducer, can be replaced by a fluid motor, for example a hydraulic motor, possibly with a speed reducer.

As already said, the first motorization unit 8 is provided with an encoder to define the angular position of each sleeve 12 and there is also, although not shown in the drawings, an electric command and control unit electrically connected to both groups of motorization 8, 17.

Finally, with reference in particular to fig. 6 and fig.

14 that the pitch P of the sleeves 12 along the tubular element 11 is equal to the pitch p between the abutment elements 14, when the carriages 3 and the respective frames 2i are arranged one against the other.

In this way each sleeve 12 is associated with a corresponding intermediate frame 2i.

Therefore, indicating each of the intermediate frames indicated as a whole with 2i with the progressive numbers 21, 22, 23, 24, each respective sleeve 12 will be indicated with the progressive numbers 121, 122, 123 and 124.

In a similar way, each corresponding carriage 3 will be indicated with the progressive numbers 31, 32, 33, 34 and the corresponding abutment elements 14 with the progressive numbers 141, 142, 143 and 144.

Operationally, the operation of the warehouse of the invention is described with reference to Figures 6 to 13 which represent precisely different views in different operating phases.

It is evident that the operation described below refers to the warehouse illustrated in the drawings which includes four intermediate mobile frames 2i and two fixed 2t, 2c, can also be referred to a warehouse composed of any number of frames, possibly also all movable on the support structure.

With reference to fig. 6 shows the warehouse 1 arranged in the configuration in which it has an access corridor C defined between the head frame 2t and the first intermediate frame 21 arranged close to all the other intermediate frames 22; 23; 24 and close to the tail frame 2c.

It can also be seen in the enlargement of fig. 7 that in this configuration the first intermediate frame 21 has the abutment element 141 included between the projecting elements 13 of the first sleeve 121.

As already said and as shown in the figures, the sleeves are each arranged angularly offset with respect to the adjacent sleeve and the value of this offset angle will vary as the number of intermediate frames making up the magazine varies. If it is intended to open a corridor C between the first and the second intermediate frame, 21 and 22 respectively, and to arrange the magazine 1 in the configuration observed in fig. 9 starting from the configuration shown in fig. 6, the second drive unit 17 is operated and the threaded shaft 18 rotates.

The displacement of the tubular element 11 towards the left is thus obtained as indicated by the arrow S in fig. 8 and since the projecting elements 13 of the first sleeve 121 contrast with the abutment element 141 of the first intermediate frame 21, this follows the displacement of the tubular element 11 and passes from the position of fig.

6 to the intermediate position shown in FIG. 8 and then to the final position shown in fig. 9, when the drive unit 17 stops.

It is thus possible to take the slabs L present in the second intermediate frame 22 by accessing along corridor C.

If at this point the operator intends to open a corridor C "between the third and fourth intermediate frame, respectively 23 and 24, so as to arrange the magazine 1 in the configuration observed in fig. 13, it is first necessary to intervene on the first drive unit 8 to rotate the tubular element 11 to release the first sleeve 121 from the first frame 21.

By means of the second motorization unit 17 the threaded shaft 18 is set in rotation again in the opposite direction to the previous one so as to move the tubular element 11 to the right in the direction indicated by the arrow D in fig. 10, until the third sleeve 123 is positioned in correspondence with the third intermediate frame 23.

At this point the second motorization unit 17 stops and the first motorization unit 8 is activated, causing the rotation of the tubular element 11 until the projecting elements 13 of the third sleeve 123 are arranged in contact with the abutment element 143 of the third intermediate frame 23, in the configuration shown in fig. 10 and better visible in the enlargement of fig. 11.

The correct positioning is defined by a precise angular displacement of the tubular element 11 imposed by the encoder present in the first motorization unit 8.

At this point, once the third intermediate frame 23 has been hooked up, the second motorization unit 17 is again operated to rotate the threaded shaft 18 again so that its displacement to the left in the direction indicated by the arrow S drags in the displacement by pushing, together with the third trolley 33, also the second trolley 32 and the first trolley 31.

At the end of the movement, the configuration shown in fig. 13 in which the first, second and third trolley, trolley 31, 32 and 33 respectively, are placed close to each other and to the head frame 2t.

Once this position has been reached in which corridor C "is defined, the second group of motorization 17 is stopped.

It is thus possible to access the fourth frame 24 to take the laminar elements that it supports.

It is evident that starting from this position and operating in the same way described, it will be possible to move any other trolley and therefore open any other corridor between any other pair of frames.

An executive variant of the warehouse of the invention is shown in particular in the overall drawings of fig. 15 and fig. 19 where it is indicated as a whole with 100.

It differs from the previously described embodiment in that it is provided with locking means, each indicated as a whole with 101, which serve to removably fasten each frame to the adjacent frame when they are arranged one next to the other, as can be seen in figs. . 15 and 19.

Each locking means 101, as can be seen particularly in figs. 16 to 18 and in fig. 20, comprises a pivoting latch 40 and a fixed bracket 50 which mutually cooperate to constrain each frame to the adjacent frame.

In particular with reference to fig. 16, each intermediate frame 2i is provided with one part of the tilting latch 40 and on the opposite side of the fixed bracket 50, while the head frame 2t is provided with only the tilting latch 40 and the tail frame 2c is provided only with the fixed bracket 50.

It can be observed in particular in fig. 18 that each swinging latch 40 is free to rotate around the pin 41 located at one of its ends and has a knife 42 on the opposite side of the pin 41 which is received in a seat 52 obtained in the fixed bracket 50.

It is also observed that each frame, in correspondence with the area where the tilting latch 40 is arranged, has a housing 60 which receives the fixed bracket 50 when two frames are arranged in contact with one another.

In particular, the insertion of the knife 42 of the tilting latch 40 into the seat 52 of the fixed bracket 50 takes place automatically in the step of approaching each frame to the adjacent frame, during the insertion of the fixed bracket 50 into the housing 60.

In fact, when the inclined plane 51 of the fixed bracket 50 contrasts against the knife 42, it progressively raises it up to the seat 52 where it releases it so that it, by spontaneous gravity fall, fits into the seat 52 making the coupling between the two frames.

On the other hand, when it is intended to separate any frame with respect to the adjacent frame in order to move it, it is necessary to intervene on the locking means 101 by releasing the pivoting latch 40 of a frame from the fixed bracket 50 of the adjacent frame.

For this purpose, the movement unit already described above which is represented in an axonometric view in fig. 21 where it is generally indicated with 70, in addition to the sleeves 12 it is also provided with a plurality of auxiliary sleeves indicated as a whole with 82, also fixed coaxially externally to the tubular element 11 and each provided with a projecting element 83.

Furthermore, the auxiliary sleeves 82 are spaced axially from each other with a pitch equal to the pitch of the sleeves 12 which corresponds to the pitch of the frames and of the tilting latches 40 consecutive to each other when the frames are coupled to each other.

Thus it can be observed that the first sleeve 121 is followed by the first auxiliary sleeve 821 which is arranged close to the second sleeve 122 which in turn is followed by the second auxiliary sleeve 822.

The latter, in turn, is placed close to the third sleeve 123 which is followed by the third auxiliary sleeve 823 which is placed close to the fourth sleeve 124 and is followed by the fourth auxiliary sleeve 824.

In the described configuration it can be seen that the projecting elements 13 of each sleeve 12 and the projecting element 83 of the auxiliary sleeve 82 which follows it, are aligned with each other according to a longitudinal axis Y 'parallel to the longitudinal axis Y defined of the tubular element 11 .

In this way, with the rotation of the tubular element 11, the rotation of the sleeves 12 is obtained which carry out the selection and coupling of the frame to be moved and at the same time also the rotation of the auxiliary sleeves 82 which, in combination with the sleeves 12, perform the € ™ opening of the locking means 101.

To better understand what has been described and what will be said below regarding the operation of the warehouse of the invention, it is appropriate to observe the enlargements of figures 16, 17 and 18 in which:

- fig. 16 represents the situation in which the two frames adjacent to each other are mutually released since the knife 42 of the tilting latch 40 of one of them is raised and therefore is not inserted in the seat 52 of the fixed bracket 50 of the other;

- fig. 17 represents the situation in which the frames are coupled together since the knife 42 of the tilting latch 40 of each is inserted in the corresponding seat 52 of the fixed bracket 50 of the other;

- fig. 18 represents the lifting of the tilting latch 40 due to the thrust action of the projecting elements 13 of a sleeve 12.

Operationally, the operation of the magazine 100 and particularly of the locking means 101 according to the embodiment variant described, are described with reference to Figures 22 to 27.

In particular in fig. 22 depicts the warehouse 100 in side view with the first intermediate frame 21 placed close to the head frame 2t which defines with the second intermediate frame 22 the corridor C for access to the laminar elements supported by the same second intermediate frame 22.

With reference to the enlarged detail of fig. 23, that the first intermediate frame 21 is hooked to the head frame 2t because the knife 42 of the tilting latch 40 of the head frame 2t is received in the seat 52 of the corresponding fixed bracket 50 of the first intermediate frame 21.

It is also observed that in this configuration the fixed bracket 50 of the second intermediate frame 22 and the tilting latch 40 opposite it, belonging to the first intermediate frame 21, are not coupled to each other.

If starting from the configuration of fig. 22 just described, it is intended to move the first intermediate frame 21 to the right as indicated by the arrow D, it is necessary first of all to rotate the tubular element 11 of the handling unit 5, so that, as can be seen in fig. 24, one of the projecting elements 13 of the first sleeve 121 raises the rocking latch 40 of the head frame 2t in the direction of the arrow A.

The knife 42 exits from the seat 52 of the fixed bracket 50 of the first intermediate frame 21 and at the same time the projecting elements 13 of the first sleeve 21 comprise between them the abutment element 14 of the first intermediate frame 21.

In this position the first intermediate frame 21 is free with respect to the head frame 2t and hooked to the handling unit 5 and can therefore be moved to the right in the direction indicated by the arrow D by activating the motorization means 7 according to what has already been previously described.

At the end of the movement, the magazine is arranged in the configuration shown in fig. 25 with the first intermediate frame 21 hooked to the second intermediate frame 22 to define the corridor C.

It should be noted that during the rotation of the tubular element 11, also the first auxiliary sleeve 821 is rotated integrally with the first sleeve 121 and the projecting element 83 with which the auxiliary sleeve 821 is provided, as can be seen in fig. 24, contrasts with the tilting latch 40 of the first intermediate frame 21, lifting it into the position shown.

It is however evident that the knife 42 of the tilting latch 40 of the first intermediate frame 21 with is constrained in no fixed bracket 50 and therefore its lifting is completely irrelevant for the purposes of release.

The intervention of the auxiliary sleeves 82, on the other hand, is decisive if, with reference to Figure 25, it is desired to open a corridor, for example between the second intermediate frame 22 and the third intermediate frame 23.

In this case, the second sleeve 122 and the second intermediate sleeve 822 are arranged so that the second intermediate frame 22 is included between them as shown in fig. 25 and through the rotation of the tubular element 11, the engagement of the abutment element 14 of the second intermediate frame 22 is caused between the projecting elements 13 of the second sleeve 122 as can be seen in fig. 26.

At the same time, its pivoting latch 40 is also raised by the thrust action of the jutting element 83 of the second auxiliary sleeve 822 which causes the knife 42 to come out of the seat 52 of the fixed bracket 50 belonging to the third intermediate frame 23.

At this point the second frame 22 is free from coupling with the third intermediate frame 23 and can be moved to the left in the direction indicated by the arrow S to open the corridor C between the second and the third intermediate frame 22 and 23 respectively observe in fig. 27.

In this situation, the fixed bracket 50 of the first intermediate frame 21 is hooked to the corresponding tilting latch 40 of the head frame 2t.

The situation represented in fig. 27.

Obviously, proceeding in the manner described, it is possible to intervene on any frame and open the corresponding corridors in any point of the warehouse.

As already said, the warehouse can be equipped with any number of frames, it being understood that the sorting unit and particularly the tubular element that equips it, must be equipped with a number of sleeves equal to the number of trolleys to be handled.

The sleeves must be angularly offset from each other along the tubular element itself by an angle corresponding to the fraction of the round angle which is obtained by dividing 360 ° by the number of frames present.

On the basis of what has been said, it is therefore understood that the warehouse of the invention, in both the described embodiments, achieves all the prefixed purposes.

In particular, it can be understood that all the movement of the frames can be carried out by means of only two motorization units which both cooperate with the sorting unit.

Motorization means and selection unit are therefore of simple construction.

Furthermore, the limited number of components in relative motion makes the operation of the warehouse more reliable and also faster than equivalent warehouses of known type.

Finally, the presence of the locking means stably constrains the frame of the warehouse in the positions reached and the actuation of the locking means also takes place through the actuation of the same motorization units which cooperate with the sorting unit.

During the execution phase, modifications not described and not represented in the attached drawing tables may be made to the warehouse of the invention.

However, it is understood that if such variants and modifications fall within the scope of the following claims, they must all be considered protected by this patent.
