Description

technical area

The The invention relates to transport pallets, especially for transport heavy, voluminous and fragile objects, such as cabinets for Processing of electrical signals by means of integrated circuits, are suitable. The invention applies in particular to pallets for the transport of cabinets of data processing devices. The transport usually includes the operations handling, actual transport and storage.

State of technology

A ordinary Pallet consists of a pallet plate with two floors, the connected by plates, which the passage of the forks the lift trucks and pallet trucks.

There are other types of further improved pallets included in the patents EP 0692431 and EP 0778215 described in the name of the Applicant. The pallets described in these two patents each have a bottom and plates. A cabinet is placed on a respective pallet and can be moved by a pallet truck.

Out US Pat. No. 4,694,962 (Basis for the preambles of claims 1 and 9) and EP A 0 673 845 a multiple pallet is known, which by rigid Assembly of two simple pallets is made.

In general, the delivery of cabinets to a customer is preceded by several steps. A first series of steps is performed at the supplier:

• 1) First and foremost, the cabinets are wired together.
• 2) Then they are configured.
• 3) Afterwards, several technicians perform a series of tests on the cabinets to check that they are working properly.
• 4) After the series of tests, the cables are pulled out and each cabinet is installed on a respective pallet and by an individual pallet truck or pallet truck in a trailer.
• 5) Finally, every pallet is transported to the customer.

• 1) erstens darin, Schränke einzeln zu depalettieren.
• 2) Anschließend werden die Schränke erneut miteinander verkabelt
• 3) und erneut konfiguriert.
• 4) Schließlich führen mehrere Techniker erneut eine Reihe von Tests an den Schränken durch, um zu überprüfen, ob sie einwandfrei funktionieren.

A second series of steps is performed and persists at the customer

• 1) First, to depalletise cabinets individually.
• 2) The cabinets are then re-wired together
• 3) and reconfigured.
• 4) Finally, several technicians once again perform a series of tests on the cabinets to verify that they are working properly.

The size The problem is that the processes of Cabling, configuration and testing are redundant. The the totality of these processes dedicated time can demand a technician up to one working day. This has high time costs for the supplier and even more unacceptable money costs for the customer result.

Also required a cabinet very strict handling conditions. First, these cabinets are very expensive. They consist of miniaturized electric and electronic elements to adhere to the very strong integration the circuits in a semiconductor material and adapt to the electrical signals with very high frequency the shortest Ways to offer. These components and their assembly are therefore very fragile and do not bear strong shocks. In addition, a closet is very hard, on the order of magnitude of 250 kg for the middle systems up to more than 500 kg for the very large multiprocessor data processing systems. He is also very high in the order of 2.20 meters. The transport of the cabinets from the supplier to theirs Destination (the customer) therefore poses many problems. With Persons responsible for handling are generally not very concerned to the precautions, which usually for this kind of cabinet must be taken. Especially if one Pallet is placed directly on the ground, have errors on the Floor result, the focus of the pallet and the cabinet to change the assembly formed there is a risk of tilting the cabinet.

The invention

One The first object of the invention is that the operations of the Cabling, configuration and testing time so far as possible too reduce.

One second objective set by the invention is that Risks of tilting the cabinets while their transport as much as possible to reduce.

One Another goal is to have one and the other of the two preceding ones Goals with simple, low-bulk, easy-to-use and to meet little expensive means.

To the invention has a multiple pallet according to claim 1 as an object.

from that results in a method for transporting switching and / or electronic Cabinets after Claim 9.

The Example of a pallet, with reference to the attached drawings is described, leaves the features and advantages of the invention emerge.

In the drawings applies

1 is a perspective view of a multiple pallet according to the invention for the transport of cabinets;

2 is a plan view of the multiple pallet according to the invention;

3 is a perspective view of the upper parts of the cabinets;

4 Figure 11 is a side view of the multiple pallet illustrating two interconnected pallets;

5 is a detailed view of an in 1 represented plate;

and the 6 and 7 represent the way in which the multiple pallet can be relocated by lift trucks.

Around to simplify the description bear the same in the drawings Elements have the same reference numbers.

In 1 you have an example of two pallets 2 and 3 for the transport of two respective cabinets (not shown in the figure) shown. In our example, the two pallets 2 and 3 identical. These pallets 2 or 3 have a respective floor 4 and 5 on which is provided with support means formed of side panels under the floor along approximately the length of two of the opposite sides of each floor. In this case, the palette 2 with two side plates 6 and 7 provided and the pallet 3 is with two side plates 8th and 9 Mistake.

A Pallet can by a pallet truck, by the expert mostly pallet trucks or stacking conveyor is called, transported and relocated. Have these cars in particular the function of transporting pallets. These cars are with parallel forks, usually two, with a fixed one Distance and a specified depth according to defined standards provided. For this purpose, the plates have a distance and a height, which at the passage adapted to these forks are.

The size Problem, as in the introduction to Expressed, is that the operations of wiring, the configuration and the tests at the supplier and the customer are redundant.

The invention has as a subject a multiple pallet 1 arising from the assembly of two pallets 2 and 3 , which form a rigid assembly results.

These are the pallets 2 and 3 designed so that a connection with each other is possible. You can see that the two opposite sides of each floor 4 and 5 extending along a transverse axis beyond the plates to wing on one side 10 and 11 or on another side wings 12 and 13 to build.

Advantageously, the pallets are 2 and 3 so close to each other that the plates of each pallet are aligned along one and the same longitudinal axis AL.

The multiple pallet has mounting means, such as uprights or side rails, for sandwiching the assembly of the wings of each pallet therebetween. The mounting means thus have a length which is at least equal to the summed length of the wings on one of the sides of the multiple pallet. The wings become more precise 11 and 13 through two stands 14 and 15 sandwiched. The first, so-called upper stand 14 is on the wings 11 and 13 and the second, so-called lower stand under the wings 11 and 13 , The wings 10 and 12 are also sandwiched by two more stands (not shown) with a first stand on the wings 10 and 12 and a second stand under the wings 10 and 12 located. The to the wings 10 and 12 belonging stand are not shown for reasons of clarity of the drawings in this figure. One of the stands (the upper stand) leading to the wings 10 and 12 belong in, appears in 2 and bears the reference number 14b ,

The attachment of the stand to the wings can be performed by an anchoring bolt. These latter have the peculiarity that they are long, which is the assembly of the two stands 14 and 15 on the wings 11 and 13 or the other two stands (not shown) on the wings 10 and 12 allows. In the figure, for example, you can see that the ground 4 on the stands 14 and 15 through two anchoring bolts 16 and 17 is mounted. Likewise, one sees that the ground 5 on the stands 14 and 15 through two anchoring bolts 18 and 19 is mounted.

you understands therefore that, as soon as the stands are fixed, the interconnected pallets a rigid Form assembly. This rigid assembly forms the multiple pallet.

Preferably, the pallets have 2 and 3 Medium ( 20 . 21 ) respectively. ( 22 . 23 ) for holding the cabinets. Preferably, each retaining means occupies the entire length of the two opposite sides along the longitudinal axis AL. To ensure a good attachment of the stand, these holding means are of course outside the occupied by the wings surface. Just like the plates are the holding means 20 and 22 aligned along the same longitudinal axis AL. Likewise, the retaining means 21 and 23 aligned along one and the same longitudinal axis AL.

These holding means 20 - 23 In particular, they have the function of centering the cabinets in order to align the cabinets of the multiple pallet along the same longitudinal axis. The reasons for this alignment will be described in the following description.

Advantageously, each pallet includes rafters located at the end of each plate. In 1 you can see that the plate 6 with two rafters 26 and 27 is provided, which are located at their two ends. The plate 7 is with two rafters 28 and 29 provided, which are at their two ends. The plate 8th is with two rafters 30 and 31 provided, which are at their two ends. The plate 9 is with two rafters 32 and 33 provided, which are at their two ends. 5 more specifically illustrates the details of a plate and rafter and the function of raking.

We now take on the 2 and 3 Reference. 2 is a top view of the multiple pallet 1 , 3 represents an embodiment of the attachment of the cabinets to each other.

In these 2 and 3 you have shown two cabinets A2 and A3, with the pallets 2 respectively. 3 are connected. It can be seen that the stands are fixed; The assembly thus formed thus forms a rigid assembly. Advantageously, the stands ( 14 . 15 ) have a length such that their ends beyond the pallets ( 2 . 3 ) to provide shock protection means.

In this figure you can see that the pallets 2 and 3 are close to each other. All the more, the two cabinets A2 and A3 are in close proximity to each other. It can also be seen in this figure that, as previously stated, the holding means ( 21 and 23 ) respectively. ( 20 and 22 ) are aligned along the longitudinal axis AL.

A first way to attach the cabinets together consists of using mounting brackets. It is remembered that a mounting bracket one piece in the form of a right angle or a T that is the montages to consolidate. In our example, these angles are with threaded holes for pickup a screw or a bolt provided.

In the example shown, the cabinets have four side surfaces whose two surfaces FO have electrical connections or other electrical components. The two cabinets are arranged so that their open sides FO face each other so that they can be wired together. In the example shown are the open sides with mounting brackets 23 and 24 Mistake. The method of attachment, once the cabinets are wired together, is to approximate the two pallets together along the longitudinal axis. The angles are arranged so that the threaded holes of the angle 23 with the threaded holes of the angle 24 to match. It is then sufficient to insert a screw or a bolt in the holes to consolidate the two machines.

The Number of angles can of course be arbitrary.

Another way to attach the cabinets may be threaded holes ( 41 - 43 ) to be used on the cabinet. The roof of a cabinet generally carries in its corners four respective holes to the screwed ring for lifting the cabinet by means of a bridge or a crane. Once the cabinet is mounted on the pallet, the eyebolts can be removed. Preferably, the holes form groups of holes and these groups are aligned along the longitudinal axis. The method then consists of using a board (made of wood) or of metal or a bar provided with holes at such a distance that, once placed on the cabinet, the holes of the board with the Match the nuts of the cabinet. The board can then be fixed by means of screws or bolts to connect the cabinets together.

In the example shown, the pallet is made of wood. It should be noted that a possible defect in the wood can prevent the cabinets from being properly fixed. The wood can namely, for example, be absorbed by drying, etc. These are the pallets advantageously by a certain length L, the in 2 is visible, spaced.

4 represents a side view of the multiple pallet 1 In this figure you can see the stands 14 and 15 holding the two pallets 2 and 3 sandwich between them. In order to ensure a transverse displacement of the multiple pallet, the pallets are provided with rafters whose height and distance are sufficient for the passage of forks of lift trucks along a transverse axis AT. In this manner, the forks of a lift truck can be inserted under the pallet either along the longitudinal axis for longitudinal displacement of the multiple pallet or along the transverse axis to ensure transverse displacement of the multiple pallet. This is very useful when loading the pallet into a truck.

You can see in this figure, the distance L, the two floors of the two pallets 2 and 3 separates.

• – Kompatibilität mit den Materialien,
• – für die Komprimierung,
• – für den Transport
• – für die Handhabung,
• – für die Umwelt gemäß der europäischen Richtlinie 94/62/CE.

5 provides a view of the 5 in 1 In this figure you can see the ground 4 the pallet 2 , The holding means 21 is attached to the ground. Under the floor you can see the plate 6 and the rafters 26 which lies under the plate. The plate has a part of foam 6b on. In the example shown, this foam has a parallelepiped shape and is a polyethylene foam. In our embodiment, this foam is at an upper part 6A and to a lower part 6B glued. According to another variant, the foam between the parts 6A and 6C be held by bolts. In the example shown, that of the two parts 6A . 6B and the assembly formed from the foam has a parallelepiped shape. In the embodiment, the parts are made 6A and 6C wooden. Preferably, a wood adhesive is used to foam the parts 6A and 6C to connect and stick it to it. Another adhesive may be used, provided that it has satisfactory technical properties for the following conditions:

• - compatibility with the materials,
• - for compression,
• - for the transport
• - for handling,
• - for the environment according to European Directive 94/62 / CE.

Preferably are the mounting means (lower stand) of the plates by one Distance D1 separated, the for the good function of the damping means is sufficient.

Preferably, the retaining means 21 from the upper stand 14b separated by a distance D2 sufficient to form a space for clamping a cap of a protective cover. This shell may be a box that protects the assembly of the cabinets.

In this 5 you can see that the plate 6 on the ground 4 is attached. Preferably, the attachment is by a bolt 34 of the type "stove setter" with a nut of the type to be driven. The head of the bolt is sunk in a countersink and a "Belleville" seal ring is placed underneath. The tightening is such that all the parts to be joined together are in contact (light touch).

The 6 and 7 represent the longitudinal or transverse displacement of the multiple pallet 6 the forks 35 and 36 a first or manual pallet truck and the forks 37 and 38 a second manual pallet truck. These two manual pallet trucks shift the multiple pallet lengthwise. When a manual pallet truck carries a load of 2 tons and the number of pallets forming the multiple pallet is arbitrary, it is generally possible to provide at least one further manual pallet truck, most preferably at the center of the multiple pallet. The forks 39 and 40 This latter manual pallet truck is directed along the transverse axis.

7 represents a transverse shift of the multiple pallet 1 dar. According to this variant, the forks 35 and 36 and the forks 37 and 38 arranged under the multiple pallet along the transverse axis.

Of course they are other possible Variants conceivable.

The Method for assembling the multiple pallet comprises several steps, in particular the following.

Step 1

A first step is to mount cabinets A2 and A3 on the respective pallets 2 and 3 ,

step 2

Then exists the procedure in placing the pallets close to each other, causing a technician the possibility there, the cabinets to wire together and configure them.

step 3

Of the Technician can then perform a series of tests on the wired cabinets to check the good function of this.

Preferably, the pallets and follow aligned the associated cabinets along the longitudinal axis.

Step 4

As soon as the tests are completed, with the pallets aligned the following process from the approach the cabinets, So that the Angles attached in advance to the upper parts of the cabinets coincide with each other.

For example, the pallet truck shifts the pallet 2 to the pallet 3 down to the angle 24 of the cabinet A2 coincides with the angle of the cabinet A3.

Step 5

Then exists the method of arranging the assembly of the pallets side by side, So that the Plates from each pallet along one and the same longitudinal axis to be aligned, and from using the stand to the group of wings sandwich each pallet.

Step 6

He exists afterwards from screwing the two angles. At this stage, the cabinets attached.

Step 7

Finally will the multiple pallet mounted and the thus formed rigid assembly is transported to the customer.

Step 8 and end

The Multiple pallet is delivered to the customer.

The cabinets are depalletized or not and can be used immediately by the customer become.

Of the Step 5 will be over two pallets executed. If the number of palettes is greater than 2, effective fastening of the cabinets can be carried out as follows:

It is assumed that 6 pallets are to be assembled. These pallets are aligned along a longitudinal axis and are numbered from 1 to 6. A first lift truck is located at one end of the chain formed by the pallets and a second lift truck is at the other end of the chain. The first moves pallet no. 1 to pallet no. 2 and at the same time the second car moves pallet no. 6 to pallet no. 5 , You can see the cabinets 1 and 2 and the cabinets 5 and 6 Fasten. After fixing, the first car moves the two pallets no. 1 and 2 to pallet no. 3 and at the same time the second car moves pallets no. 5 and 6 to pallet no. 4 , You can see the cabinet no. 3 at the cabinet no. 2 and the cupboard 4 at the cabinet no. 5 Fasten. A final step consists, for example, of moving the pallet no. 1 . 2 . 3 formed assembly and from the same to the assembly of the pallets no. 4 . 5 . 6 or vice versa, and from attaching the cabinet 3 at the Cabinet 4 ,

In general terms, therefore, the invention has as subject matter a multiple pallet 1 for transporting loads A2 and A3 through pallets 2 and 3 where a palette 2 or 3 a respective floor 4 or 5 which is provided with support means consisting of respective lateral plates ( 6 . 7 ) and ( 8th . 9 ) are formed under the bottom along approximately the length of two of its opposite sides, the plates ( 6 . 7 ) and ( 8th . 9 ) have a distance and a height adapted to the passage of forks of lift trucks, characterized in that they are mounting means 14 and 15 having, which can firmly connect the assembly of the pallets together to form a rigid assembly.

It has been seen in our illustrated example that the two opposite sides of each floor 4 . 5 along a transverse axis beyond the respective plates 6 . 7 and 8th . 9 extend to respective wings 10 . 11 and 12 . 13 to form that the pallets 2 . 3 so juxtaposed that the plates 6 . 8th and 7 . 9 from every pallet 2 . 3 aligned along one and the same longitudinal axis and that the mounting means 14 . 15 the assembly of the wings 11 and 13 from each pallet sandwiched between them.

The Description that precedes, the expert offers numerous variants at. Of course The pallet may have several plates and the bottom of one other material than wood.

It has also been seen in our embodiment that the plates skilfully with rafters 26 - 33 whose height and spacing are sufficient for the passage of fork lift forks along a transverse axis.

Advantageously, the plates have 6 - 9 a part made up of damping means 6b that make up shock absorbers.

It has also been seen that the mounting means 14 . 15 from the plates 6 - 9 one for the good function of the damping means 6b sufficient distance are separated.

Advantageously, the floors 4 . 5 with funds 20 - 23 to hold the load on the pallet.

In order to protect the cabinets against shocks, it has been seen in the example shown that the mounting means 14 . 15 have a length such that their ends beyond the pallets 2 . 3 extend.

It has also been seen that the roof of the loads A2, A3 is advantageously provided with at least one group of threaded holes. Thus, the cabinets can be interconnected by a perforated piece, these latter holes coinciding with the holes of the cabinet, and screws or bolts connecting the cabinets together. The loads can also be with fasteners 23 . 24 be provided to connect the loads together. In our illustrated example, it has been seen that these fasteners were, for example, mounting brackets.

• – Montieren mindestens eines Schranks A2, A3 auf einer jeweiligen Palette 2, 3,
• - elektrischem Verkabeln der Schränke A2, A3 miteinander,
• - Zusammenfügen der Paletten 4, 5 durch Montagemittel 14, 15,
• und es besteht aus dem Transportieren der so gebildeten Montage von Paletten.

The method for transporting the switching and / or electronic cabinets A2, A3 is also apparent from the description. It exists before the transport from the

• - Mount at least one cabinet A2, A3 on a respective pallet 2 . 3 .
• electrical wiring of cabinets A2, A3 together,
• - Assembling the pallets 4 . 5 by mounting means 14 . 15 .
• and it consists of transporting the assembly of pallets thus formed.

you has seen in our example before assembly, that the pallets separated by a sufficient distance to allow a technician the closets connects electrically.

• – dem Anordnen der Baugruppe der Paletten 2, 3 nebeneinander, so daß die Platten 6, 8 und 7, 9 der Paletten, die nebeneinander stehen, entlang ein und derselben Längsachse ausgerichtet sind,

• – und aus dem Transportieren der so gebildeten starren Baugruppe.

It has been seen that the assembly can consist of

• - arranging the assembly of the pallets 2 . 3 next to each other, so that the plates 6 . 8th and 7 . 9 the pallets, which are next to each other, are aligned along one and the same longitudinal axis,
• - using the mounting means 14 . 15 to sandwich the assembly of the wings of each pallet,
• - And from the transport of the rigid assembly thus formed.

It has also been seen that once the pallets 2 . 3 stand side by side, the transport method of attaching the cabinets A2, A3 can exist together.

It has also been seen in our example that the method consists of equipping the plates 6 . 7 and 8th . 9 with rafters 26 - 32 whose height and spacing are sufficient for the passage of fork lift forks along a transverse axis.

After all, in our example, it has been seen that it comes from equipping the plates 6 . 7 and 8th . 9 with damping agents 6b to dampen the shocks.

It it is clear that the Invention offers numerous advantages. The multiple pallet makes it possible do not reconnect, reconfigure and reconnect to the customer To repeat tests. The assembly of cabinets works from arrival to customer without intervention of technicians. The time gain is therefore considerable. The installation of the cabinets at Customers are simply limited to depalletizing or non-depalletizing the cabinets.

One greater The advantage is that it the multiple pallet allows any number of cabinets, the electrically connected, configured and wired are to transport.
