DESCRIPTION

Procedure and device for load transfer

The present invention relates to a method and a device for transferring loads.

It refers more particularly to a gravitational transfer device of the type comprising a tubular body that delimits a longitudinal passage that crosses it, this tubular body being at one of its extremities called a perforator, shaped in a tip to allow the perforation of a sack whose content You have to transfer.

The transfer of materials from continents of great capacity, such as large bags, is problematic, since the latter are extremely difficult to handle. However, there are numerous applications where it is necessary to quickly and easily empty this type of continent to transfer its content, either to smaller continents, or to specific locations.

A transfer device for the transfer of loads, in particular bulk materials, conditioned on continents of the bag type, is disclosed in document fR-2,895,728. This device comprises a tubular body that delimits a longitudinal passage through it, this tubular body being at one of its extremities, called a perforator, formed in a tip to allow a perforation of said sack.

A purpose of the present invention is therefore to propose a transfer device of the aforementioned type, whose simple and robust conception allows a quick and easy gravitational transfer of materials contained in sacks, in particular of large dimensions.

For this purpose, the object of the invention is a transfer device for the transfer of loads, in particular of bulk materials, conditioned on sack-like continents, said device comprising a tubular body that delimits a longitudinal passage through it, this being tubular body at one of its extremities, called a perforator, shaped in a tip to allow a perforation of said sack, this tubular body being equipped with at least one sealing member of the mobile mounted passage between a closed position and an open position of said passage and being provided, on its outer peripheral surface, in the area of the body that extends between the sealing member and the piercing tip, of legs, characterized in that the legs are mounted at least partially mobile between a position called inactive, close to said body, and a position called active, separated from said body, and because the area of said body that can being sealed by said sealing member is disposed separate from the open end of the body opposite the piercing end of said body to delimit, between the open end and the area that can be sealed, a connection zone of said device.

The perforating end of the device allows a perforation, from the outside, of said sack whose content must be transferred and, as a consequence, the at least partial introduction of said body inside the sack to a position in which the legs extend in active position inside the bag after being moved from an active position to an inactive position at the level of the body insertion opening in the bag, formed by the perforation of said bag. In active position, the legs prevent any untimely exit of the device out of the bag.

The presence of a tubular connection zone capable of allowing a connection, generally by fitting the device with a receiving bag or a so-called transfer conduit allows a safe and rapid transfer of the load from the bag perforated by the device to the receiving bag. This results in a considerable time gain for the user.

Thanks to the presence of a sealing organ, the transfer can be interrupted at any time, so that the risk of overflow of the receiving bag is controlled. Likewise, the emptying of the bag perforated by the device can be carried out according to a rhythm and a flow chosen by the operator.

Preferably, the legs are elastically deformable legs equipped with elastic request means one to a separate position of said body.

Generally, the elastic request means of a leg are made in one piece with the leg and are formed by the elasticity of said leg that tends to take this leg to a separate position from said body. Thus, the legs are foldable against the body to a position in application against said body during the partial introduction of the body inside the bag before being redeployed by separating said body, once inserted inside the bag. In this separate position, they are able to rest on the inner wall of the bag and to retain at least a part of the body inside said bag, so as to prevent any untimely exit of the device outside the bag.

Preferably, the legs are radial-type legs with a radial arrangement around said body and are inclined with their free end as far as possible from the piercing end of the body than its connecting end to the body.

Preferably, at least some of the legs are disposed at the same level on the outer peripheral surface of said body and at least some of the legs are associated with an opening that crosses the intended body, on the outer peripheral surface of the body, between the leg and body piercing tip.

The presence of these openings that pass through it allows almost the entire bag to be emptied.

Preferably, the tip of the piercing tip has a general conical shape, which facilitates perforation of the bag and partial penetration of the device into the bag.

Preferably, the sealing member is a pivotal sealing member mounted movable to pivot about an axis preferably parallel to the longitudinal axis of the passage delimited by said body.

Such a pivot assembly allows an adjustable flow shutter organ to be easily obtained.

Preferably, the tubular body is divided into at least two sections each provided, on one end, with an outer peripheral collar, said collars being positioned opposite each other in the coupled state of said sections delimiting between them a free space suitable for be occupied at least partially by said sealing organ. One of the collars also forms a limit stop for the introduction of the body inside the bag to be emptied.

Preferably, the collars are, in the coupled state of said sections, assembled together by threading, one of the thread bodies forming the axis around which the sealing member for pivoting is mounted. It results in a simplification of the construction.

Preferably, the body is equipped with a handle or handle to catch it disposed at the level of the area of said body that can be sealed by said sealing member. This handle or handle also forms a visual reference means of the open or closed position of the shutter.

Preferably, the device comprises a tie, such as a loop, a strap or cord, a collar that can be positioned around the connection zone to allow in particular the maintenance of a continent called receiver in the state fitted by its neck over the connection zone of the device.

Preferably, the limb of the body, opposite the piercing limb, is provided with an outer peripheral collar. This collarm forms a stop that prevents the sliding of the tie beyond the limb of said body. This collar also makes it possible to prevent an ascension of material along the connection area of the device during the transfer phase.

The object of the invention is still a method of transferring loads, in particular of bulk materials, conditioned on continents of the bag type with the aid of an aforementioned device, said method comprising, in a closed position of the sealing member, a perforation stage of said sack, preferably at the level of the bottom of the sack, with the aid of the piercing end of the device until the introduction of the piercing end and of at least some legs inside said sack, an opening stage of the sealing organ, and if necessary, at least before the opening stage of the sealing organ, a stage of fixing a continent called a receiver or a guide conduit at the level of the connection area of the device.

The invention will be better understood by reading the following description of embodiments, with reference to the accompanying drawings in which:

Fig. 1 represents a front view of a device according to the invention in use position, the sacks between which the load transfer is established transparently to allow a visualization of the parts of the device arranged inside the sacks;

This transfer device 1 therefore comprises a tubular body 2 that delimits a longitudinal passage 5 that crosses it. In the examples shown, this body 2 is made of metal. One of the extremities represented in 3 in the figures of said body is shaped in a tip with a general conical shape. This tip-shaped piercing tip 3 is here made with the help of inclined arms that converge from the peripheral edge of said body towards the free end of the tip.

The device even comprises a sealing member 4 of step 5. In the example shown, the sealing member 4 is a pivotal sealing member mounted movable to pivot about a substantially parallel axis, that is to say parallel with about ten degrees, to the longitudinal axis of step 5 delimited by said body for the movement of said sealing organ 4 between an open position and a closed position of said passage. This sealing member 4 comprises a vane 41 provided with a lateral perforation for the assembly to pivot said sealing member and a rod 42 of radial maneuvering to the vane.

The tubular body 2 is in itself divided into at least two sections each provided, on one end, with an outer peripheral collar 9, said collars 9 being positioned opposite each other in the coupled state of said sections delimiting each other a free space 10 between them suitable to be occupied at least partially by said sealing organ 4.

The collars 9 are, in the coupled state of said sections, assembled between them by threading, one of the thread bodies 11 forming the axis around which it is mounted mobile so that the sealing member 4 pivots.

In the open position of step 5, the vane 41 does not extend mostly outside the perfometer delimited by the tubular body 2. In the closed position of step 5, the vane 41 does not extend mostly to the interior of the perfometer delimited by the body 2 in a position represented in strokes in fig. 5. Thus, in the course of its passage from the closed position to the open position, said shutter organ progressively releases step 5 allowing the flow rate to be adjusted.

In the example shown, the body 2 is equipped with a capture handle 12 arranged at the level of the area

15 of the body 2 that can be sealed by said sealing organ 4. In the closed position, the handle 12 and the maneuvering rod of the sealing member extend diametrically opposite. It is thus easy for the operator to visually reference the closed position of the sealing organ. For a progressive opening of step 5, the maneuvering rod 42 is progressively approximated to the handle 12.

The sealing member could also have been made in the form of a pivoting sealing member about an axis perpendicular to the longitudinal axis of said passage, but this solution is less practical.

The transfer device 1 still comprises, on the outer peripheral surface of the body 2, in the area of the body 2 that extends between the sealing member 4 and the piercing tip 3, legs 6, in this case, here, four legs 6 mounted at least partially mobile between a position called inactive near said body 2 and a position called active separated from said body 2.

These legs 6 are elastically deformable legs, equipped with an elastic request means at a separate position from said body 2.

In the example shown, each leg forms one of the branches of a bent piece whose other branch forms the part of fixing the leg to the body. This fixing part is applied on the outer peripheral surface of the body, and held in a support position by threading, riveting or other form.

In the example shown, said legs 6 are arranged at the same level, on the outer peripheral surface of said body 2 and are each associated with an opening 8 that passes through the body 2 provided on the outer peripheral surface of the body 2 between the leg 6 and the piercing tip 3 of the body 2.

Each leg 6 is regularly displaced from another leg by 90 °. These legs come to be applied against the outer peripheral surface of the body during the introduction into the sack of said body, at the level of the opening in the bag 20 before being deployed once the insertion opening in the bag has been exceeded as illustrated fig. 1 where the legs are in an active position that prevents any untimely exit of the device through the perforation opening through which it has entered the bag.

The device even comprises a tubular connection zone 7 of the device disposed between the open end 14 of the body opposite the piercing end 3 of the body and the area 15 that can be sealed from said body.

This connection zone 7 is formed by the part of the body that extends between the open end 14 of the body and the zone 15 that can be sealed and allows a connection generally by fitting of a receiving bag 21 as illustrated in fig. 1 or a conduit for example.

For the maintenance of the receiver bag 21 at the level of this connection zone 7, the device 1 comprises a tie

16 such as a loop, a strap or a collarm that can be positioned, in the manner of a ligature, around the connection zone 7, and around the outer peripheral surface of the neck of the receiving bag fitted by its neck on

said connection zone 7.

To achieve this fixation, the tip 14 of the body 2, opposite the piercing tip 3, is provided with an outer peripheral collar 13, which prevents any slippage of the tie beyond the tip 14 of the tubular body 2.

5 The transfer of loads between the bag 20 and the receiver bag 21 can, with the aid of the device 1 described above, be carried out as follows: the device 1 is, with its sealing organ 4 in a closed position, positioned on the bottom of the bag 20 a empty, which in turn is held high with the help, for example, of a forklift. The device 1 is positioned on the ground in the erected state of the tubular body with its piercing tip 3 pointing in the direction of the bottom of the bag. The bag is lowered to the bottom of the bag by the piercing tip 3 that penetrates the bag as the latter is lowered.

The introduction of the device into the bag continues until the legs 6 of the body approach the body to enter the bag before separating from the body to retain the device inside the bag. On the opposite end 14 of the body, at the level of the connection zone 7, a receiver bag 21 is fixed or has been fixed and the bag 20 is positioned at a height that allows a gravitational circulation of the charges from the bag 20 towards the I take out 21 to 15 through step 5.

The sealing organ 4 can then be opened to allow this gravitational circulation.

When the receiving bag 21 is filled, the sealing organ 4 is brought to a closed position and a new receiving bag 21 can be positioned on the device 1 to proceed to a new transfer operation.

When the emptying of the bag 20 to be emptied is finished, the device 1 can be removed from the bag to be emptied and positioned 20 on a new bag to be emptied.
